Background: Lipid disorder is a modifiable risk factor for diseases related to plaque formation in arteries such as heart attack, stroke, and peripheral vascular diseases. Identifying related factors and diagnosis and treatment in time reduces the incidence of non-communicable diseases (NCDs). The aim of this study was to determine factors associated with lipids based on a national survey data. Methods: Data of 16757 individuals aged 25–64 years obtained from the Iranian STEPwise approach to NCD risk factor surveillance (STEPs) performed in 2016, through multistage random sampling, were analyzed. Because of clustered, hierarchical, and skewed form of the data, factors related to total holesterol (TC), triglycerides (TG), low-density lipoprotein-cholesterol) (LDL-C), high-density lipoprotein-cholesterol) (HDL-C), TG/HDL-C, TC/HDL-C, and LDL-C/HDL-C were determined applying multilevel quantile mixed model. Parameters of the model were estimated on the basis of random effect of the province as well as urban or rural area for 10^th, 25^th, 50^th, 75^th, and 90^th quantiles. Statistical analyses were performed by R software version 4.0.2. Results: Significant relationship was found between age, body mass index (BMI), waist circumference (WC), diabetes, hypertension, smoking, physical activity, education level, and marital status with TC, LDL-C, HDL-C, LDL-C, and LDL-C/HDL-C. With increasing BMI and WC, subjects had higher levels of serum lipids, especially in higher quantiles of lipid levels. Lipid levels were significantly increased among smokers and those with diabetes or hypertension. The random effects were also significant showing that there is a correlation between the level of lipids in provincial habitants as well as urban and rural areas. Conclusions: This study showed that the effect of each factor varies depending on the centiles of the lipids. Significant relationship was found between sociodemographic, behaviors, and anthropometric indices with lipid parameters.

Background: Diabetes has become an important health problem in the world. Natural agents, with antidiabetic property, are potential candidates for improving diabetes. Urtica Dioica Distillate (UDD) or Araghe Gazaneh is widely used for the treatment of diabetes as per traditional medicine. Despite the tremendous use of UDD as an antidiabetic compound in folk medicine, the antidiabetic effects of UDD has been neglected by medical scientists. In this study, we aimed to evaluate the effects of UDD on the glucose metabolism in diabetic rats. Methods: A total of 24 male rats were divided equally into four groups, two treatment and two control groups, each containing normal or Streptozotocin (STZ)–induced diabetic rats. During 4 weeks, control and treatment rats received water or UDD, respectively. Fasting blood sugar (FBS), HbA1c, serum creatinine, blood urea nitrogen, and specific activities of hepatic enzymes including glucokinase (GK), hexokinase (HK), glucose-6-phosphate dehydrogenase (G6PD), and muscle glucose transporter type 4 (GLUT4) and liver phosphoenolpyruvate carboxykinase (PEPCK) mRNA levels were measured. Results: FBS and HbA1c increased in diabetic groups. Treatment with UDD significantly lowered FBS and prevented weight loss. Decreased FBS level was associated with higher activity levels of GK and HK in UDD-treated diabetic rats. G6PD-specific activity decreased in diabetic control rats compared to nondiabetic ones, but UDD treatment improved it to the normal levels. A significant decrease in the expression level of GLUT4 was observed in diabetic control rats compared to nondiabetic ones, but UDD increased it to the normal levels. Conclusions: These findings suggest that UDD might exert therapeutic effects against diabetes by improving glucose metabolism and can be used as an alternative or complementary medicine for the treatment of diabetic patients.

Background: The authorities recently emphasized the importance of dietary control for COVID-19 patients in hospitals. However, there is limited detail about the obesity and death of COVID-19 patients who are hospitalized in the Asian and Western countries. The aim of this study was to find the role of obesity and mortality of the hospitalized COVID-19 patients. A systematic review of the studies on obesity and mortality of hospitalized COVID-19 patients in the Asian and western countries. Methods: Databases of ProQuest, PubMed, and EBSCO were used to find relevant articles published between January 2020 and March 2021. A total of 3,70,836 patients in 17 studies were included. Results: We found significant correlation between obesity and mortality in hospitalized COVID-19 patients (pooled odds ratio [POR] = 1.28, 95% CI: 1.23–1.33). In particular, this study demonstrated that the Asian countries had higher POR (1.44, 95% CI: 1.16–1.79) compared to the western countries (1.28, 95%CI: 1.23-1.33). The heterogeneity calculation showed heterogenous among studies included (I² > 50%). Conclusions: The mortality of COVID-19-hospitalized patients is related to obesity, which requires a multi-stakeholder mitigation approach to avoid and control obesity and its impacts.

Background: Patients with inflammatory bowel disease (IBD) suffer from a wide range of comorbidities such as migraine. In studies, the prevalence of migraine in cases with IBD was reported differently. The goal of this systematic review and meta-analysis was to estimate the pooled prevalence of migraine in IBD cases. Methods: Two researchers independently and systematically searched PubMed, Scopus, EMBASE, Web of Science, and google scholar. They also searched the gray literature including references of the included studies and conference abstracts which were published up to May 2021. Cross-sectional studies were included. Results: The literature search revealed 840 articles, and after deleting duplicates, 650 remained. For the meta-analysis, 10 studies were included. Totally, 62,554 patients were evaluated. The pooled prevalence of migraine in patients with IBD was 19% (95% CI: 15–22%). The pooled prevalence of migraine in ulcerative colitis (UC) was 10% (95% CI: 4–15%) (I² = 99.8%, P < 0.001). The pooled prevalence of migraine in the Crohn's disease (CD) group was 24% (95% CI: 17–30%) (I² = 98.8%, P < 0.001). The pooled odds of developing migraine in IBD cases was 1.51 (95% CI: 1–2.27) (I² = 90.8%, P < 0.001). Conclusions: The result of this systematic review and meta-analysis showed that the pooled prevalence of migraine in patients with IBD was 19% (95% CI: 15–22%).

Background: Both aging and diabetes are two well-established risk factors related to type 3 diabetes and memory deficits. Accordingly, diabetes multiplies the effects of aging on cognition impairments once these conditions occur simultaneously. Methods: In this present experimental study, 56 male Wistar rats with HFD/STZ-induced T2D were randomized into seven groups (n = eight animals per group): (1) sedentary old non-diabetic (C); (2) sedentary HFD/STZ-induced T2D (D); (3) sedentary HFD/STZ-induced T2D plus UA (UA) (DU); (4) endurance-trained HFD/STZ-induced T2D (DE); (5) resistance-trained HFD/STZ-induced T2D (DR); (6) endurance-trained HFD/STZ-induced T2D plus UA (DEU); and (7) resistance-trained STZ-diabetic plus UA (DRU) rats. Two-way ANOVA was applied to measure the training, supplementation, and interaction effect on serum and gene expression outcomes. Result: The study results established no significant interaction effect between the UA supplementation and the resistance/endurance training with regard to the levels of glucose (P = 0.534), insulin (P = 0.327), brain-derived neurotrophic factor (P = 0.191), and insulin-like growth factor-1 (P = 0.448). Conclusions: To develop novel practical nutritional strategies involving UA intake, further studies are thus needed to clarify how chronic consumption of UA with/without resistance/endurance training reverses cognition disorder process in old male Wistar rats with HFD/STZ-induced T2D.

Introduction: Food waste reflects inadequate food intake and is of economic and environmental importance. Therefore, understanding the underlying factors is a must to combat food waste. Methods: A qualitative study was conducted using semi-structured interviews with managers, nurses, nutritionists, food providers, kitchen staff, and inpatients at three hospitals in Tehran. Responses were recorded, coded, and analyzed thematically. Results: Forty-eight face-to-face interviews led to three core categories: 1. opinions/performance; 2. causes, related factors, and characteristics; and 3. rooting and suggestions. We found that the majority of the hospitalized patients did not consume their entire food. In spite of overall satisfaction with the quantity and quality of food, anorexia, personal taste, and poor quality of raw materials prohibited patients from eating. Also, rice was the most discarded food. Economic barriers were the most important hindrance to elevate the quality, and some strategies, like the supply of high-quality materials and recruiting skillful cooking team, were proposed to improve it. Conclusions: Our findings delineated a limited budget as the main barrier to improve the quality. Nevertheless, the low quality of hospital foods may actually impose a heavier economic burden due to food waste.

Background: The alteration of DNA cytosine methylation is one of the most common epigenetic changes that can play a significant role in human cancers. The enzymes involved in DNA methylation of promoter regions of the genes are DNA methyltransferases (DNMTs). The therapeutic activities and apoptotic effects of DNA methyltransferase inhibitors (DNMTIs) have been reported in various cancers. This study was assigned to assess the effect of zebularine on intrinsic and extrinsic pathways, DNAT 1, 3a, and 3b, p21, and p53, viability, and apoptosis in hepatocellular carcinoma (HCC) cell lines. Methods: Hepatocellular carcinoma cell lines (HCCLM3, MHCC97H, and MHCC97L) were purchased from the National Cell Bank of Iran, Pasteur Institute, treated with zebularine, and the MTT assay was performed. Then, flow cytometry assay and real-time RT-PCR analysis were performed with zebularine. Statistical comparisons between groups were made using GraphPad Prism software version 8.0. A significant difference was considered as P < 0.05. Results: Zebularine up-regulated DR4, DR5, FAS, FAS-L, TRAIL, Bax, Bak, Bim, p21WAF/CIP1 (p21), and p53 and down-regulated DNMTs (DNAT 1, 3a, and 3b), Bcl-2, Bcl-xL, and Mcl-1, significantly resulting in apoptosis induction in HCC cell lines. Maximal and minimal apoptosis was seen in HCCLM3 and MHCC97L cell lines, respectively. Conclusions: Our findings indicated that DNMTI zebularine can induce apoptosis and inhibit cell growth through both pathways (extrinsic and intrinsic) in HCC cell lines HCCLM3, MHCC97H, and MHCC97L.

Background: Cardiovascular diseases (CVDs) are recognized as one of the leading causes of death worldwide. Studies have shown the impact of genetic predisposition and dietary factors on developing these diseases. Dietary patterns and genetic factors such as polymorphisms related to the level of adiponectin may also interact with each other and produce variances in the effects of these factors on different individuals. The purpose of this study is to investigate the interactions between food intake patterns and polymorphisms on ADIPOQ and ARL15 genes in relation to cardiometabolic risk factors. Methods: This cross-sectional study is conducted on 380 adults (20 to 70 years old) living in Yazd, Iran. Individuals were selected from the participants in Yazd Health Study (YaHS) and its sub-study called Taghziyeh Mardom-e Yazd (TAMYZ) after reviewing the inclusion and exclusion criteria. YaHS is a population-based cohort study which has been conducted on 9962 adults living in Yazd since 2014. In the present study, rotated principle component analysis (PCA) with Varimax rotation is used to identify the major dietary patterns. The polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP) method is used in order to identify rs1501299 and rs6450176 variants (on ADIPOQ and ARL15 genes, respectively). General linear models (GLM) as well as regression models are used to investigate the interactions between the studied genotypes and the extracted dietary patterns. Conclusions: The results of this study can help to personalize dietary recommendations for the prevention of CVDs according to the genetic predisposition of individuals.

Background: Diclofenac (DIC) is an NSAID that can cause toxic effects in animals and humans and carvacrol (CAR) is a monoterpene compound that displays effective pharmacological and biological actions. The purpose of this work was to assess the influences of CAR on DIC-induced liver injury and oxidative stress in male rats. Methods: The male Wistar rats were segregated into four groups. Group 1, the control group; Group 2 received DIC-only (10 mg/kg BW, p.o); Group 3, received CAR-only (10 mg/kg BW, p.o), and group 4 received DIC plus CAR. The serum levels as well as the activity of several liver-associated markers, and oxidative and anti-oxidant compounds were tested. The expression of pro-inflammatory mediators was also studied using the qRT-PCR analysis. Results: Our results showed that DIC treatment was associated with the elevation in the serum levels of liver-related markers together with the increase in the serum and the hepatic levels of malondialdehyde (MDA) and protein carbonyl (PC). Moreover, DIC reduced the activity of the antioxidant system in the rats and increased lymphocyte infiltration into the hepatocytes. CAR; however, protected the hepatocytes from the toxic effects of DIC by enhancing the activity of antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx), and Glutathione (GSH). By diminishing the expression of tumor necrosis factor (TNF)-α, CAR was also capable of preventing the inflammatory effects of DIC on liver cells. Conclusions: The findings of this study indicated that the administration of CAR could alleviate the noxious effects of DIC on the antioxidant defense system and liver tissue.

Background: Equitable distribution of health care sector resources is one of the most important goals of health systems in all countries. The purpose of this study is to measure equity of geographical distribution of active specialist physicians in Iran's health system. Methods: The present study was a descriptive-cross-sectional. The statistical population included: all active specialist physicians working in the public, private, social insurance organization, military, charity, and the other health service providers in Iran in 2019. Studied demographic data were collected from Iran's national statistic center. Also, information of specialist physicians was obtained from several databases. Finally, duplicated records were removed, and the number of specialist physicians extracted. Data analysis was performed using Stata V.16 and ArcGIS 10.4 software. Results: The results showed that the number of specialist physicians per 100,000 population who worked in Iran's health system was 46.81. The provinces of Tehran had the highest and Sistan and Baluchestan had the lowest number of specialist physicians. Also, 52.63% of active specialist physicians provide health services in four provinces, whereas these provinces are 37.13% of the country's population. Total Gini coefficient of the distribution of active physicians in Iran in 2019 was 0.23. Conclusions: Distribution of specialist physician was different but somewhat equitable in the provinces. However, in some provinces, the ratio of specialist physicians to the population was still low. Therefore, when the number of specialist physicians increased, their distribution should be considered concurrently.

As the population of patients recovering from COVID-19 grows, post COVID-19 challenges are recognizing by ongoing evidences at once. Long COVID is defined as a syndrome with a range of persistent symptoms that remain long after (beyond 12 weeks) the acute SARS-CoV-2 infection. Studies have shown that long COVID can cause multi-organ damages with a wide spectrum of manifestations. Many systems, but not limited to, including respiratory, cardiovascular, nervous, gastrointestinal, and musculoskeletal systems, are involved in long COVID. Fatigue and dyspnea are the most common symptoms of long COVID. Long COVID-19 may be driven by tissue damage caused by virus-specific pathophysiologic changes or secondary to pathological long-lasting inflammatory response because of viral persistence, immune dysregulation, and autoimmune reactions. Some risk factors like sex and age, more than five early symptoms, and specific biomarkers have been revealed as a probable long COVID predicator discussed in this review. It seems that vaccination is the only way for prevention of long COVID and it can also help patients who had already long COVID. Managing long COVID survivors recommended being in a multidisciplinary approach, and a framework for identifying those at high risk for post-acute COVID-19 must be proposed. Possible therapeutic options and useful investigation tools for follow-up are suggested in this review. In sum, as evidence and researches are regularly updated, we provide the current understanding of the epidemiology, clinical manifestation, suspected pathophysiology, associated risk factors, and treatment options of long COVID in this review.

Background: Due to lack of contemporary data on the presentation, management, and mortality of acute coronary syndrome (ACS) admissions in Iran, in this prospective registry study, we aimed to evaluate the presentation, management, and mortality as the outcome of patients with ACS in Isfahan, Iran, 2001–2016 to address treatment and healthcare depletions. Methods: Data of 62,276 patients admitted with the diagnosis of ACS from 2001 to 2016 prospectively were obtained by Surveillance Unit of Isfahan Cardiovascular Research Center, Isfahan, Iran, in 13 hospitals of Isfahan province. We evaluated data on presentation, management, and in-hospital and 28-day mortality. Results: Nearly half of the patients ranged in age from 51 to 70 years (32050, 51.5%), which did not differ among ACS types (ST-segment myocardial infarction (STEMI): 53.9%; non-STEMI: 53.4%; unstable angina: 51.9%). In-hospital, anti-platelets use was high (84.9%). Thrombolytic were used in 48.1% of STEMI, 3.8% of non-STEMI, and 1.1% of unstable angina. Discharge medication rates were suboptimal. In-hospital and 28-day mortality were highest for STEMI (6.5 and 12.6%, respectively). Conclusions: These data represent the large ACS registry in Iran. Data revealed the various presentations of ACS and demonstrated opportunities for improving ACS management by focusing on increasing use of recommended drugs especially after discharge due to suboptimal medical treatment in these patients. The high mortality rate needs to be taken into consideration in ACS patients.

Background: One of the most effective strategies to improve the access of community members to health services is to regionalize health services. The purpose of this study is to examine and prioritize measures that could help to counteract obstacles and problems in implementing the regionalization of healthcare in Iran. Methods: The study relied on a mixed research method, including qualitative and quantitative phases. First, by conducting semi-structured interviews and analyzing them through qualitative content analysis, the obstacles and measures were identified. In the quantitative phase, the obstacles identified were weighted using the fuzzy best-worst method (FBWM), and the measures were then prioritized through the fuzzy TOPSIS (FTOPSIS) method. Results: The obstacles were categorized into four main dimensions: “infrastructural,” “political,” “human resources,” and “managerial.” Among the 15 obstacles identified, “absence of performance guarantees” was the most important obstacle, while “insufficient education” was the least important obstacle to the regionalization of healthcare services in Iran. Meanwhile, the following eight measures that could help to overcome the obstacles were extracted from the interviews: “conducting a needs assessment,” “providing clinical guidelines,” “employing specialized human resources,” “reinforcing the referral system,” and “preparing electronic health records,” “enhancing education and information dissimilation,” “building executive support,” and “providing cost-effective equipment and technology.” “Employing specialized human resources” was also the most effective measure to overcome the obstacles. Conclusions: Iranian healthcare policy-makers can use the empirical findings of this investigation to accelerate the implementation of Iran's regionalization plan to improve the access of community members to healthcare services.

Background: This study is to determine the effect of the family-centered intervention (FCIS) on the key indicators of diabetes management and Control control in patients with type-2 diabetes. Method: The present study is a quiz- experimental study with a randomized control group. Participants were 64 patients with type-2 diabetes visiting Ali Asghar Hospital of Isfahan in 2018. The eligible patients were assigned to either the intervention group or the control group (i.e., patient-center care) through block randomization. FCIS were implemented in 4 two-hour sessions as home visits while the patients and their caregivers were present. Data were collected twice-i.e. before the intervention and 12 weeks after it- and were analyzed, by running a t-test (α = 0.05), using SPSS-21. Results: The mean ± SD age of participants was 50.4 ± 8.5. There was no significant difference between the two groups in the mean weight, serum levels of FBS and A1C, physical activity, energy intake, and BMI before intervention. But, a significant improvement in the mean values of these variables in the intervention group after the intervention, compared with the control group was indicated (P < 0.05). Conclusions: This study suggests that FCIS are more effective than patient-center care in the management and control of type-2 diabetes. Therefore, it is recommended that the family be considered in educational interventions.

Introduction: The COVID-19 pandemic has created several challenges for countries all over the world. Different countries have taken different measures to fight this pandemic and reduce its challenges depending on their cultural, economic, and social structures. This study aims to understand and explain the Iranian health system's response to fighting the COVID-19 pandemic from the managers' and authorities' perspective. Method: This study is a basic applied research performed under a qualitative approach. In the survey, 30 experts including the managers of health centers and deputies and heads of the Ministry of Health and Medical Education and Medical Universities were selected by purposive snowball sampling and participated in semi-structured interviews from March to May 2020. The researchers explained the actions of the Iranian health system in fighting the COVID-19 pandemic in 2020 by content analysis. Results: As a result, 14 subthemes were found and classified into four major themes, including the informative and regulative actions (two subthemes), administrative and supportive actions (six subthemes), preventive and curative actions (three subthemes), and resource-related actions (three subthemes). Conclusions: Due to its strong health structures, such as urban and rural health networks, various general and specialized hospitals, experienced doctors, and committed health staff, Iran has taken practical actions in fighting the COVID-19 pandemic. However, the findings of this study and its relevant measures can help combat this pandemic in countries with similar social and cultural structures or counter future similar crises.

Each research roves around the P value. A value less than 0.05 is considered to be statistically significant. Very few researchers are aware of the history, real-world significance, statistical insight, and in-depth criticism about this monumental alphabet of research. This article will provide detailed insight into the most common molecule of research which will be rewarding for the young students and researchers in the primary world of research. It is not a simple value; it is the longest and broadest description of research squeezed to a number for the ground level worker to the principal investigator. The present review will provide a detailed and unique insight into the P value which would be rewarding for the primary care physicians toward translating research into their clinical practice.

Background: Hematological inflammatory indices are currently suggested to assess systemic inflammation. This study aims to investigate a vitamin D supplementation effect on hematological indices of inflammation in rats. Method: Forty-eight middle-aged male rats were allocated into a normal diet (ND) group (10% fat) and a high-fat diet (HFD) group (60% fat). The animals were fed for 26 weeks. After this period, each group was randomly divided into three subgroups, each of 8 rats: Group (1): animals were fed the ND and HFD containing 1 IU/g vitamin D for 4 months, group (2): animals were fed the ND and HFD containing 6 IU/g vitamin D for 4 months and group (3): animals were euthanized to evaluate the HFD effect. Serum 25-hydroxyvitamin D level, white blood cell count (WBCs), platelet count, platelet crit (PCT), mean platelet volume (MPV), platelet distribution width (PDW), platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR) were measured. Results: The HFD, significantly increased body weight, PCT, PDW, PLR, NLR, and MLR and significantly reduced serum vitamin D levels compared to the ND (P < 0.05). There was a significant decrease in food intake, MPV, PDW, and NLR after vitamin D supplementation in the ND-fed group (P < 0.05). A significant reduction in platelet count, PCT, and MLR was observed after vitamin D supplementation in HFD-fed rats (P < 0.05). Conclusions: In our study, some hemogram-derived inflammatory indices were higher in the HFD-fed group, and vitamin D supplementation lowering effects on some hematological indices were seen in both ND and HFD groups.

Background: Research has examined the relationship between salivary lactate dehydrogenase (LDH) levels and head and neck squamous cell carcinoma (HNSCC) screening and prognosis. Due to biochemical changes in cancer cells and increased production of lactate products in the body. The present systematic review aims to evaluate the changes in salivary LDH levels in HNSCC patients. Methods: The present study is a systematic review and meta-analysis. The data were collected by searching PubMed, Science Direct, Scopus, Web of Science, and Google Scholar from 2000 to 2021. The heterogeneity of the articles was analyzed using I² and TAU². Results: After searching the databases, of 988 articles, 665 duplicated articles were excluded by adopting the inclusion and exclusion criteria. So, 25 articles were primarily selected to be reviewed and evaluated for quality. Finally, 19 articles were selected and analyzed according to the Newcastle–Ottawa checklist. A total of 642 HNSCC patients were reviewed. The meta-analysis showed salivary LDH levels in the HNSCC group were higher than the control group (mean difference = 0.675, standard error = 0.058) (P < 0.001). Conclusions: As the research results showed, a significant correlation was observed between salivary LDH levels and HNSCCs. So, LDH can be employed as a valuable and minimally invasive biomarker in head and neck cancer screening and prevention.

Background: Several animal studies have shown the protective effect of silymarin (the extract of Silybum marianum seeds) against anti-tuberculosis drug-induced hepatotoxicity (ATDH). However, the knowledge of ATDH of silymarin in humans is scarce. In this study, we aimed to clinically evaluate it. Methods: During this randomized controlled clinical trial, 36 new cases of tuberculosis (TB) were enrolled to receive either silymarin 150 mg twice daily for two weeks along with a standard anti-TB therapeutic regimen (experimental group; n = 16) or standard anti-TB therapeutic regimen alone (control group; n = 21). Liver function tests (serum AST, ALT, ALP, and total bilirubin) at the end of weeks 1 and 2 as well as the rate of ATDH during the study were determined and compared between the groups. Results: No significant differences between the experimental and control groups were observed at the end of the first week regarding liver function tests; However, at the end of the second week, the mean serum levels of AST (P = 0.03) and ALP (P = 0.04) were significantly lower in the experimental group. ALT (P = 0.016) and ALP (P = 0.027) levels in the experimental group significantly decreased during the study, while the changes in the control group were not significant. Two patients in the control group (9.5%) developed ATDH, while no one in the experimental group manifested this adverse effect. Conclusions: Our study suggests that silymarin use has the potential for the reduction of anti-TB drug-induced hepatotoxicity.

Background: Sodium arsenate (Na 3As0 4, Sodium As) is an important toxic substance that leads to nephrotoxicity. Due to having bioactive molecules, such as polyphenols and tyrosol, olive oil plays a significant role in scavenging free radicals. This study aimed to investigate the effects of olive oil and tyrosol on As-induced nephrotoxicity. Methods: In our study, 42 adult male BALB/c mice were randomly divided into six groups: control (normal saline), olive oil (0.4 ml/d, gavage), tyrosol (5 mg/kg/d), Sodium As (15 mg/kg), olive oil + Sodium As, and tyrosol + Sodium As (olive oil and tyrosol received one hour before Sodium As). Drugs were administreted once daily for 30 consecutive days. On the 31^st day of the study, oxidative stress parameters in kidney tissue, FRAP in plasma, renal function parameters in serum, and histopathological assays were performed. Results: Sodium As-induced renal damage as characterized by a significant increase of creatinine and BUN (P < 0.001) and histopathological changes. Also, Sodium As markedly altered oxidative stress biomarkers such as a significant increase in MDA (P < 0.001) and significantly decreased in FRAP and GSH (P < 0.01). Olive oil and tyrosol administration significantly improved the renal antioxidant defense system and decreased MDA concentration, markedly preserving the tissue structure and functional markers of kidney. However, these effects were more effective for tyrosol than olive oil. Conclusions: Our results suggest that olive oil and tyrosol can be used as a protective agent in preventing Sodium As-induced nephrotoxicity due to antioxidant property.

Background: Ulcerative colitis is one of the major phenotypic forms of inflammatory bowel diseases. The present study aimed to investigate the effect of force swimming exercise on clinical symptoms (disease activity index; DAI), colon histopathology, inflammation and fibrosis, and oxidant/antioxidant balance in dextran sulfate sodium (DSS)-induced colitis mice. Methods: Male C57BL6 mice were randomly divided into five groups (n = 6 each): control, exercise, colitis, colitis + sulfasalazine, and colitis + exercise. Exercise was performed by forced swimming six weeks before and during the experiment. Colitis was induced by 1.5% DSS in drinking water. The animals were evaluated for body weight changes and DAI (including changes of body weight, stool consistency, rectal bleeding, and prolapse) during the induction of colitis and treatment. At the end of experiment, colons and spleens were evaluated by H and E and Masson Trichrome stainings. Oxidant (Malon dialdehyde; MDA), and antioxidant markers [total thiol groups, superoxide dismutase (SOD), and catalase activity] were also measured in colon tissue. Results: Results indicated that exercise in colitis mice significantly improved DAI, colon length, spleen weight, and histological injury score and alleviated fibrotic changes in colon tissue that were comparable to sulfasalazine group. Exercise also restored the oxidant/antioxidant balance in colitis mice by reducing MDA and increasing antioxidative markers including total thiol groups, SOD, and catalase activity. Conclusions: Taken together, aerobic exercise could improve clinical symptoms and colonic inflammation through, at least, the balancing the oxidative stress markers. Thus, it can be considered in management of colitis patients as effective method.

Background: In the present study, we investigated the effect of two doses of atropine eye drops versus placebo on myopia progression in children and adolescents. Methods: In this double-blind, randomized clinical trial, 67 patients aged 6 to 18 years with myopia of -2 to -6 D were enrolled and randomized to receive a placebo eye drop, atropine 0.1%, or 0.01% ophthalmic solution (one drop per night for 6 months). All participants were followed-up with for one year after the beginning of the study (at zero, one, three, six, and 12 months) and their spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), and far and near visual acuity (VA) and the eye drops side effects were recorded. A comparison among the groups was performed using SPSS software, version 24.0. Results: Spherical equivalent, AL, and ACD decreased and far VA improved in atropine groups to a greater extent than the placebo group (P < .05) at the 6-month follow-up. The most common side effects of atropine 0.1% eye drop included photophobia and decreased near VA. At the end of the study (six months after the cessation of atropine), a rebound effect was observed; this effect was especially severe in the 0.1% atropine group. Conclusions: Atropine eye drops are effective for slowing down and preventing myopia progression. However, without long-term treatment, they will have a rebound effect. A lower dose (0.01%) is suggested for reducing the side effects and rebound effects.

The family physician program (FPP) is one of the most significant health care reforms in Iran; however, many studies showed that this program has not been able to achieve its intended objectives because of a variety of challenges. This program, despite the existing challenges, is going to be expanded across the country. To improve the likelihood of its success, identification of the structural and infrastructural challenges is necessary. This systematic review was conducted to assess the structural and infrastructural challenges of FPP in Iran. This systematic review of the literature was conducted in order to investigate the infrastructure and structure needs of the current program in Iran. All published articles related to the FPP in Iran were the subject of this study. The eligibility criteria included original articles, reviews, or case studies published in English or Persian during 2011–2021 related to the challenges in the referral system of FPP in Iran. Data were extracted based on Sample, Phenomenon of Interest, Design, Evaluation, Research type technique and were reported based on the structure of Preferred Reporting Items for Systematic Reviews and Meta-Analyses. International credible scholarly databases were searched. The search strategy was defined based on keywords and the search syntax. This study identified different challenges of the referral system in the areas associated with legal structure, administration, and social structure. The identified challenges in this program should be addressed in order to ensure that this program will lead to improved quality of care and equity in Iran health care system.

As per the goals of the family physician program, it is essential to pay attention to the effectiveness and performance of FPP. Although the implementation of the FPP program is an important development in the discussion of rural health insurance and the provision of health services and referral systems in the country, the evidence suggests that by identifying challenges and taking appropriate action, this plan can be improved. This study aimed to investigate the challenges of rural Family Physician Policy (FPP) in northern Iran. This study comprised a mixed method. The former intended to identify the challenges of rural FFP using the narrative review method. To achieve a comprehensive list of challenges, a narrative review and content analysis were performed and semi-structured interviews were held with key stakeholders of FPP in the north of Iran, including physicians, managers, and policymakers. Identified challenges were categorized into eight categories including the weakness of the health insurance system, low comprehensiveness of executive guidelines, inappropriate recruitment and maintenance of human resources, weakness of cultural context, low efficacy of health information management system, poor educational effectiveness, inappropriate motivational mechanisms, and weakness of the referral system. As per the quantitative findings, “weakness of the referral system” and “inappropriate recruitment and maintenance of human resources” had the lowest and highest weaknesses, respectively. To address existing challenges in the rural FPP, a comprehensive plan of action should be developed with an emphasis on human resource management, health information management system, comprehensive rural health insurance, and legislation.

Background: This study aimed at evaluating the accuracy of the pediatric appendicitis scoring method in differentiating nonspecific abdominal pain (NSAP) from appendicitis. Methods: This cross-sectional study was conducted on 391 children who were hospitalized in the emergency ward due to acute abdominal pain suspected of appendicitis . Pediatric Appendicitis Score (PAS), C-reactive protein (CRP), and appendicitis pathology results of patients undergoing surgery were recorded. Results: The results showed that the no significant difference was found among patients in the three experimental groups (appendicitis, specific abdominal pain except appendicitis, and NSAP) with respect to temperature (p = 0.212), but the other variables were significantly different. Findings showed that high CRP frequency, pain migration to right lower quadrant (RLQ), tenderness in right iliac fossa (RIF), anorexia, leukocytosis, high neutrophil, and mean tenderness in RLQ in the appendicitis group were higher than those in the other two groups (p = 0.001). The PAS questionnaire can also be used as a reliable questionnaire with appropriate sensitivity (0.929) and specificity (0.993), and this questionnaire along with detailed clinical examinations could reduce the rate of negative appendectomy to less than 1%. Conclusions: This study showed high accuracy of PAS in diagnosing children with appendicitis and differentiating appendicitis from cases of NSAP and specific abdominal pain other than appendicitis. The PAS system could also significantly reduce cases of negative appendicitis. Although high CRP had an excellent ability to diagnose appendicitis, its accuracy was lower than PAS.

Introduction: COVID-19 is a respiratory disease caused by infection with severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2). Thrombotic complications appear to be of particular importance in patients with COVID-19. This study aimed to investigate Changes in the level of Antiphospholipid antibodies (Anticardiolipin and Anti-β2-glycoprotein-I) and thromboembolic indices in COVID-19 patients during 3 weeks. Methods: This cross-sectional study was performed on adults with Covid-19 hospitalized at Al-Zahra Hospital in Isfahan. The case group includes the patients admitted to the internal ward or ICU who despite receiving prophylactic or anticoagulant doses suffer from thrombotic complications and the control group includes COVID-19 patients without thromboembolic events. The sample size of 120 people was considered. Anticardiolipin and anti-β2-glycoprotein-I antibodies, coagulation profiles including Fibrinogen, PTT, PT Troponin, ESR, CRP, and D-dimer were examined. After collection, the data were entered into spss24 software and analyzed. Results: The results showed that there was no statistically significant difference in the changes of anticardiolipin and anti-beta-2 glycoprotein in IgM and IgG as well as in the changes of ESR, CRP, PTT, PT, and fibrinogen in the two groups (P > 0.05). Conclusions: Our study showed that there was no statistically significant relationship between anti-phospholipid antibodies (anticardiolipin and anti-beta-2 glycoprotein) and thromboembolic events. Therefore anticardiolipin and anti-beta-2 glycoprotein is probably the puzzles causing thrombosis in COVID-19 patients, and other inflammatory responses should be examined among the cases.

Background: Bisphenol-S (BPS), as a new human public health concern, was introduced to the plastic industry by BPA-free labeled products following the restrictions of Bisphenol-A (BPA) as a safe alternative. However, recent research has revealed a controversial issue. In this regard, the present study aimed to review the relationship between BPS exposure and reproductive system dis/malfunction. Methods: PubMed and other databases were searched up to January 2021. The standard mean difference (SMD) with a 95% confidence interval (CI) was calculated for the main parameters using the random-effects model. Finally, 12 studies with 420 subjects were included in this research. Forest plot, meta-regression, and non-linear dose-response effect were calculated for each parameter by random-effects model. Results: Based on the results of in vitro assessment, a significant increase was found in the oxidative stress parameters, including superoxide dismutase (SMD: 0.63, 95% CI: 0.321, 0.939), thiobarbituric acid reactive substances (SMD: 0.760, 95% CI: 0.423, 1.096), and reactive oxygen species (SMD: 0.484, 95% CI: 0.132, 0.835). In addition, the hormonal assessment revealed a significant decrease in male testosterone concertation (SMD: -0.476, 95% CI: -0.881, -0.071). Moreover, in vivo examination revealed a significant decrease in hormonal parameters, such as female testosterone (SMD: -0.808, 95% CI: -1.149, -0.467), female estrogen (SMD: -2.608, 95% CI: -4.588, -0.628), female luteinizing hormone (SMD: -0.386, 95% CI: -0.682, -0.089), and female follicle-stimulating hormone (FSH) (SMD: -0.418, 95% CI: -0.716, -0.119). Besides, linear and non-linear correlations were detected in the main parameters. Conclusion: In conclusion, based on the current meta-analysis, BPS was suggested to be toxic for the reproductive system, similar to the other bisphenols. Moreover, a possible correlation was indicated between oxidative and hormonal status disruption induced by BPS in male and female reproductive systems dis/malfunction.

Background: Preeclampsia (PE) is a pregnancy-related syndrome with moderate mortality. Early diagnosis of the condition remains difficult, with the current diagnostic modalities being ineffective. The varying microRNAs (miRNAs) as a novel biomarker pose an alternative solution with their potential to be reviewed. Methods: This study follows the Preferred Reporting Item for Systematic Review and Meta-Analysis Extended for Scoping Review (PRISMA-ScR). PubMed/MEDLINE, CENTRAL/Cochrane, ProQuest, Science Direct, and Wiley Online Library were used for this review. We only include observational studies. A critical appraisal was assessed in this study using QUADAS-2. Results: We retrieved 30 observational studies fulfilling the set criteria. Data extracted were synthesized qualitatively based on miRNAs that are more prominent and their area-under-the-curve (AUC) values. In total, 109 distinct dysregulated miRNAs were identified in comparison to healthy controls, with 10 of them (mir-518b, mirR-155, mirR-155-5p, miR-122-5p, miR-517-5p, miR-520a-5p, miR-525-5p, miR-320a, miR-210, and miR-210-3p) being identified in two or more studies. A brief look at the results shows that 49 miRNAs are downregulated and 74 miRNAs are upregulated, though the fold change of the dysregulation in all studies is not available due to some studies opting for a visual representation of the differences using whisker plots, bar charts, and heat map diagrams to visualize the difference from the reference control. Conclusions: This study has analyzed the potential of varying miRNAs as potential diagnostic biomarkers and how they might be used in the future. Despite this, potent miRNAs identified should be more emphasized in future research to determine their applicability and connection with the pathogenesis.

Background: Eye health is essential for quality-of-life. The present study aimed to design an eye care behaviors assessment instrument for the student community and evaluate its psychometric properties. Methods: The present mixed-method cross-sectional study was conducted in two sections using Creswell and Plano Clark methods for instrument development. The study was conducted in Isfahan, Iran, in 2021. The first section (textual analysis and qualitative research) explained and developed the instrument's fundamental items. This section included in-depth, semistructured interviews with 21 students and eight experts. The second section measured the psychometric properties of the instrument. Twenty students assessed the instrument's qualitative and quantitative face validity in this section. The instrument's content validity ratio (CVR) and content validity index (CVI) were evaluated. In addition, exploratory factor analysis (performed by 251 students) was used to establish construct validity. Internal and test–retest reliability was determined using Cronbach's alpha and intraclass correlation coefficients (ICC), respectively. Results: During face and content validity assessment, a 37-item questionnaire was finalized. Exploratory factor analysis led to the identification of three factors, including “examinations and glasses-related behaviors,” “symptom-related behaviors,” and “screen-related behaviors.” The three extracted factors accounted for 37.9% of the variance. Cronbach's alpha was equal to 0.874 when evaluating internal consistency, and the ICC value for the total score of the questionnaire was 0.885 (0.810–0.941), indicating excellent test–retest reliability. Conclusions: These results demonstrate the questionnaire's validity and reliability. This instrument assesses the prevalence of university students' most significant eye health risk behaviors. Consequently, it helps prevent eye problems.

Background: As a public health emergency, coronavirus disease 2019 (Covid-19) is a threat to our future; therefore, appropriate health system responsiveness (HSR), as an important criterion, is of crucial importance. This study aimed to evaluate the different dimensions of responsiveness of healthcare centers, both public and private, providing COVID-19 services in Tehran. Methods: Following a cross-sectional design, this study was conducted in Tehran (the capital city of I.R. Iran) from May to November 2020. Data were collected using the World Health Organization (WHO) questionnaire on responsiveness. Two hundred questionnaires were filled out through face-to-face or phone call interviews in two public and private hospitals (100 in each) providing Covid-19 services. Participants were selected using the convenience sampling technique among all those who received Covid-19 services during the past six months in the city of Tehran. Results: The mean age of participants was 45.9 ± 15.9 and 51.5% were female. On an average, 52.6% of the respondents evaluated at least one dimension of responsiveness as appropriate and/or strongly appropriate. Communication obtained the highest score (58.2%), followed by confidentiality (56.5%), dignity (56%), and prompt attention (52%). Meanwhile, autonomy and choice were evaluated as poor (moderate, weak, and strongly weak) by 63.5 and 52.5% of respondents. There was no significant association between the type of healthcare center (i.e., public or private) and responsiveness (p-value = 0.896). However, there was a significant difference between gender (p-value = 0.036) and education level (p-value = 0.014) with responsiveness. According to the respondents, prompt attention and choice were the most and least important dimensions, respectively. Conclusions: Evaluation of HSR in the era of COVID-19 not only provides a tool for qualitative assessment of services but also plays an important role in providing feedback to policymakers to adopt effective policies.

Background': India is ranked second in the world in terms of tobacco use and tops the list of eight high-burden countries that account for two-thirds of the new tuberculosis (TB) cases globally. As tobacco smoking among TB patients is associated with unsuccessful TB treatment outcomes, effective smoking cessation interventions for TB patients is essential to combat this double pandemic. Aim: The study determined the effectiveness of nicotine replacement therapy (NRT) on smoking reduction and cessation among pulmonary TB patients. Settings and Design: The study included 300 pulmonary TB patients undergoing antitubercular treatment in government health care centers of Dakshina Kannada district in southern India. Materials and Methods: The participants in this two-armed, single-blinded, placebo-controlled, block-randomized trial were divided equally (n = 150) for experimental arm (brief advice + NRT) and control arm (brief advice + placebo). The total duration of treatment and follow-up was 6 months. Unadjusted relative risk (URR) and adjusted relative risk (ARR) were calculated for treatment outcomes at 95% confidence interval (CI). Generalized linear regression analysis was performed upon variables with P value less than 0.2. Results: After 6 months of intervention including follow up, there was a significant reduction in self-reported smoking (ARR = 1.08, 95% CI 1.01–1.17, P = 0.03) in the experimental arm compared with the control arm. Biochemically verified smoking abstinence was not significantly different between the two arms (ARR = 1.01, 95% CI 0.72–1.38, P = 0.97). Conclusion: The study showed statistically significant effectiveness of NRT for self-reported smoking reduction.

Background: This study aimed to design and evaluate the cooling power of local cooling coats for the head, neck, ankles, and wrists. Methods: Local cooling coatings were designed using Iranians workers' existing 50^th anthropometric percentile data. After immersing the cooling coats in water for 5 minutes, they were placed in a chamber at 30°C, 35°C, and 40°C and 30% and 60% humidity and 0.2-0.4 m/s air velocity for 120 minutes. The amount of water evaporation was measured by weighing each coat before and after entering the chamber, and then the cooling power of each coat was calculated based on the amount of water evaporation. Results: The average cooling power of cooling coats with covering areas (two wrists 933.75 cm², two ankles 1467.37 cm² and head and neck 1270 cm²) that the total area of the cover is 3671.12 cm², i.e., about 20% of the body at 30% relative humidity in 30°C, 35°C and 40°C was 67, 77 and 89 watts, respectively. At the mentioned temperature and in 60% relative humidity, the cooling power was 34, 40, and 55 watts. As the relative humidity increased, the cooling power of the coats decreased. Conclusions: Local evaporative cooling coat on the head, neck, wrists, and ankles can reasonably repel excess heat entering the body. The best performance of these coats is in hot and dry environments. Probably, if used in conjunction with cooling vests in environments with high temperatures and heavy activity, it can act as a supplement to cooling vests and have a significant effect on improving functions.

Background: The aim of the study was to assess the prevalence and correlates of cardiovascular health (CVH) status among adults in Afghanistan. Methods: In a national cross-sectional household survey 3,447 adults completed CVH measurements in Afghanistan. Criteria for ideal CVH (ICVH) were physical activity, healthy diet, non-smoking, fasting blood glucose (<100 mg/dL), body mass index (<25 kg/m²), total cholesterol (<200 mg/dL), and blood pressure (<120/<80 mmHg). Results: More than one-third (34.3%) of participants had 5-7 ICVH, 45.7% 3-4 ICVH, and 20% had 0-2 ICVH. In adjusted logistic regression analysis, secondary or more education (AOR: 1.80, 95% CI: 1.22-2.66) was positively associated, and older age (45-69 years) (AOR: 0.33, 95% CI: 0.26-0.42), and urban residence (AOR: 0.67, 95% CI: 0.51-0.88) were inversely associated with 5-7 ICVH. Conclusions: The prevalence of ICVH was low in Afghan adults. Population measures may be used to improve CVH targeting identified associated factors.

As reports of the first national study reveal, Iranian salt intake reaches 9.52 g/day (two times more than recommended by World Health Organization). Meanwhile ignoring the consequences of high salt intake has led to an increased rate of cardiovascular diseases (CVD), stroke, stomach cancer, osteoporosis, obesity, etc., To tackle these threatening issues, a nationwide intervention campaign could be an effective solution based on global experiences. A review of previous work in Iran shows that despite numerous efforts conducted in the prevention of CVDs, they were not well reflected in worldwide sources. Furthermore, a comprehensive campaign was not implemented particularly concerning the salt reduction in Iran. As a result, we first reviewed the major successful initiatives conducted in reducing salt intake around the world and Iran. Then we introduced the components of a comprehensive social marketing campaign along with customized actions related to Iranian nutrition habits, their attitude, and behavior toward salt consumption. These employed components were SWOT analysis, identifying target group, determining communication goals and objectives based on models and theories, planning executive plan, designing communication messages and materials, media planning and promotional actions, and determining campaign budget plus monitoring and evaluation.

Background: Aging is identified as a risk factor for vitamin D deficiency (VDD) therefore this investigation was designed to determine the prevalence of VDD and its determinants in a sample of older adults. Methods: The data of this study were obtained from the baseline wave of the Longitudinal Aging Study (LAS). Demographic, past medical history, medication history, and smoking behavior were collected using an interview approach. The physical activity and nutritional status of the participants were assessed using a standard questionnaire. Anthropometric indices were measured according to a standard protocol then body mass index (BMI) was calculated. Serum vitamin D and calcium levels were measured by autoanalyzers. Univariate and multiple logistic regression models were applied to detect the associated factors with VDD. Results: Mean age of the participants was 71.82 (SD = 7.63) years. A total of 1319 people participated in our study, and 51.16% (n = 688) were female. A total of 8.42% (n = 111) of the participants had VDD and 17.06% of them (n = 225) had insufficient vitamin D levels. In the multivariable logistic regression model, the age group of 70–79 years in comparison with the age group of 60–69 years had a 43% less chance of VDD. Furthermore, being overweight (OR = 0.36, P = 0.01) and obese (OR = 0.35, P = 0.02), and taking vitamin D supplements (OR = 0.31, P = 0.04) were significantly associated with VDD. Conclusions: Our results showed that 25% of older adults had vitamin D deficiency or insufficiency. In addition, some modifiable lifestyle factors were associated with VDD. Given that, old age is considered a risk factor for VDD. Therefore, detection and improvement of VDD may be a preventive measure in at-risk subjects.

Background: Obstructive sleep apnea (OSA) is the most common sleep-realted respiratory disorder. It is frequently comorbid with cardiovascular, cerebrovascular, and metabolic diseases and is commonly observed in populations with these comorbidities. Investigators aimed to assess the effect of OSA on glycemic control in patients with diabetes. Methods: In this cross-sectional study, 266 adult patients with diabetes mellitus (DM) attending the outpatient endocrinology clinic at the Guilan University of Medical Sciences were enrolled. Patients completed a checklist that included demographic characteristics, factors, and laboratory results in addition to Berlin and STOP-BANG questionnaires to evaluate the risk of OSA. Data were analyzed by independent t-test, Mann–Whitney U test, and Chi-squared or Fisher's exact tests using the Statistical Package for the Social Sciences (SPSS) version 17. Results: A total of 266 patients with DM were enrolled in this study (34.6% males, mean age 47.00 ± 19.04 years). Based on the Berlin Questionnaire, 38.6% of all participants were at high risk of developing OSA. Based on the STOP-BANG Questionnaire (SBQ), 45.1% were at moderate and high risks. Additionally, this questionnaire showed a significant difference between low and moderate-to-severe groups regarding sex, age, body mass index (BMI), neck size, other chronic diseases, types of DM, use of insulin, Berlin Questionnaire, fasting blood sugar (FBS), and mean HbA1c. Conclusions: Based on the SBQ, our results indicated a significant relationship between OSA and glycemic control according to mean HbA1c and FBS. Therefore, by controlling the OSA, we may find a way to acheieve better glycemic control in diabetic patients.

Background: Repeated contact with patients with COVID-19 and working in quarantine conditions has made health workers vulnerable to psychological distress during the COVID-19 pandemic. The goal of the present systematic review and meta-analysis was to examine the prevalence of the various psychological distresses among health workers during the COVID-19 pandemic. Methods: PubMed, Scopus, Web of Science, EMBASE, and Cochrane databases were searched for access to papers examining psychological distress among healthcare workers during the COVID-19 pandemic. Risk of bias was assessed using the Newcastle–Ottawa Scale (NOS). Heterogeneity among the studies was examined using the Cochran's Q test; because heterogeneity was significant, the random effects model was used to examine the prevalence of psychological distress. Results: Overall, 12 studies with a total sample size of 5265 were eligible and included in the analysis. Prevalence rates of depression, anxiety, and PTSD were 20% (95% CI: 14–27), 23% (95% CI: 18–27), and 8% (95% CI: 6–9), respectively. The highest prevalence rates of depression and anxiety were related to the SDS and the GAD-7, respectively, and the lowest prevalence rates of the two aforementioned variables were related to the DASS-21. Conclusions: The high prevalence of psychological distress among healthcare workers during the COVID-19 epidemic can have negative effects on their health and the quality of services provided. Therefore, training coping strategies for psychological distress in this pandemic seems necessary.

Background: The dietary approaches to stop hypertension (DASH) encourages high fruit, vegetable, and lean protein consumption and low salt, red meat, and fat intake to prevent or treat hypertension. However, besides hypertension, adherence to this diet has been shown to decrease other cardiovascular risk factors. Methods: This study assessed the relationship between the DASH diet and cardiovascular risk factors in a cross-sectional study of 2,831 adults chosen by multistage cluster sampling from 27 counties of Khuzestan province, Iran. DASH scores were calculated using data obtained from a qualitative food frequency questionnaire. Regression models were used to evaluate the association of DASH scores and common cardiovascular risk factors. Results: Significant trends were observed across quintiles of DASH scores for systolic blood pressure, fasting blood sugar, triglyceride, total cholesterol, and its components (p < 0·05). After adjusting for potential confounders such as sex, age, ethnicity, residence, wealth score, physical activity, energy intake, and family history of heart disease, the multiple regression analysis for each cardiovascular risk factor revealed that being in the highest quintile of total DASH score (OR = 0.72, 95% CI 0.52–0.99) was negatively associated with hyperglycemia. Conclusions: This study showed a positive relationship between DASH diet adherence and lower serum levels of glucose, triglycerides, and cholesterol. Prospective studies are needed to confirm these findings.

Background: A further understanding of the mechanisms linking inflammation to T2D and related complications can help prevent or control this silent but dangerous disease. This study was conducted to determine the association between paraoxonase 1 (PON1) activity and interleukin-6 (IL-6) in type 2 diabetes (T2D). Furthermore, we have evaluated the role of age and gender in the relationship between the PON1 activity and IL-6. Methods: A total of 105 people with T2D were enrolled in this study. IL-6 levels were determined using ELISA. For the PON1 activity assay, the hydrolysis rate of the substrate phenylacetate was spectrophotometrically assayed in serum at 270 nm. The determined velocities were the initial velocities of substrate hydrolysis. Results: PON1 activity was negatively correlated with IL-6 in total data (r = −0.34, P = 0.001). In both groups with age ≥50 and <50 years, PON1 activity was negatively correlated with IL-6, but the correlation was significant in patients aged 50 years and above (r = −0.358, P = 0.005) compared with patients with age <50 years. In both women and men, PON1 activity was negatively correlated with IL-6, but the correlation was significant in women (r = −0.318, P = 0.006) in comparison with men. Conclusions: Inverse association between PON1 activity and IL-6 in T2D may represent the oxidative–inflammatory interaction in this disease. Our findings highlight that at older ages and in women, the associations between lower PON1 activity and higher IL-6 concentrations are more evident, and this should be considered in patients with T2D.

Background: Launched in September 2018, the ABPMJAY is the world's largest publicly funded health insurance (PFHI) program with population coverage of 500 million. A systematic review was conducted. Methods: A comprehensive literature search was conducted in four databases: PubMed, Web of Science, Scopus, and Google Scholar. The literature search was conducted with the search terms: “Ayushman Bharat OR ABPMJAY OR modicare AND RSBY.” The search was set to title and abstract. Gray literature and government websites were also searched for relevant documents. A total of 881 documents were identified (PubMed: 53, Web of Science: 46, Scopus: 97, Google Scholar: 681, government websites: two, and gray literature: two). Fifty-two duplicates were identified. After the elimination of the duplicates, 829 unique documents were identified. These 829 unique citations were then subjected to a review of title and abstract independently by 2 reviewers. Six-hundred and ninety-two articles were rejected after review of title and abstract. One-hundred and thirty-seven articles were screened for full text independently by two reviewers. Sixty-six articles were rejected after review of the full text. Disagreements were resolved by discussion. Seventy-one unique articles were included in the final review. To attain the objective of the study, which is to critically analyze and provide an overview of Ayushman Bharat, a narrative synthesis was performed. Results: Seven themes were identified from the review: (1) health and wellness centers (HWCs); (2) out-of-pocket health expenditure (OOPHE); (3) fraud; (4) upcoding and provision of unnecessary medical care; (5) moving focus away from primary care; (6) coverage; and (7) lop-sided access, exclusion at the periphery, and brain drain. There is very little impact evidence of the ABPMJAY available. Conclusions: The government could plan impact evaluation studies in every state that the ABPMJAY is functional in. Any high-quality feedback generated might enable the National Health Authority, the government body leading and coordinating the ABPMJAY, to take necessary steps operationally and advice the government on strategy. Another concern is that the ABPMJAY PFHI might negatively impact the ongoing process of continuous strengthening and development of the government health-care system at all levels—primary, secondary, and tertiary. Continual recalibration and course corrections on the basis of high-quality feedback might enable ABPMJAY reduce catastrophic OOPHE for 500 million Indians. This is more than 6% of humanity: the largest block of people served by a single PFHI in history.

Background: Childhood type 1 diabetes mellitus (T1DM) is an autoimmune disease which is increasing in incidence, but little is known about the events that trigger the autoimmune process. Most of the time, these processes begin in prenatal and natal periods; therefore, this study aimed to investigate the prenatal and neonatal risk factors of T1DM in childhood. Methods: This case-control study has been performed on children with T1DM who referred to the 17^th Shahrivar children's hospital. The control group consisted of healthy siblings of the case group. Data were gathered using a form that included maternal and neonatal characteristics. Data were reported by descriptive statistics in SPSS 19. To investigate the effect of quantitative and qualitative variables on the development of T1DM, logistic regression and Chi-square tests were used, respectively. Results: Birth weight, birth height, and maternal weight gain during pregnancy had a significant relationship with T1DM (odds ratio [OR] = 1.23, 2.57, and 1.14, respectively). In addition, there was a significant relationship between gestational hypertension (OR = 5.27), neonatal jaundice (OR = 3.42), cesarean section (OR = 2.06), and being non–first-born child (OR = 2.32) and T1DM. Also, premature rupture of membrane, maternal urinary tract infection, and nonexclusive breastfeeding had a significant association with T1DM (OR = 4.37, 3.94, and 2.30, respectively). There were no statistically significant differences between maternal age, sex, neonatal respiratory disease, prematurity, and neonatal infections and T1DM (P > 0.05). Conclusions: Prenatal and neonatal risk factors can have a significant role in the occurrence of TIDM. Therefore, considering these risk factors can have a preventive effect on T1DM.

Background: During the COVID-19 pandemic, stunting is estimated to increase 2.4 times higher (It seems that some information is missing here because the usage of the word 'higher' hints at a comparison with some other statistic. Or please consider making the following changes in the statement: “…stunting is estimated to be 2.4 times higher than the normal trend.” which can increase mortality, morbidity, and cause economic losses in the future. This study aims to identify the risk factors for stunting during the COVID-19 pandemic. Methods: An unmatched case-control study was conducted to compare the exposure of stunted (cases) and non-stunted (controls) children. There were 127 children aged 6-24 months, 43 cases, and 84 controls. Results: The probability of stunting was two times greater in children who experienced good changes in the consumption of tofu/tempeh (p: 0.047; AdjustedOR (aOR): 2.296; 95% CI 1.013-5.205) and fourtimes greater in children who have a mother that did not receive iron supplementation during pregnancy (p: 0.030; aOR: 4.344; 95% CI: 1.154-16.355). Conclusions: Based on the above results, increasing access to nutritious food, and the delivery of services and information related to maternal and child health services during the pandemic needs to be intensified by using innovative low-risk platforms.

Background: The risk of developing tobacco-related cancer and chronic heart and lung disease is greater if addiction starts in adolescence. Even experimental use of tobacco in adolescents significantly increases the risk of addiction in adulthood. This study intends to collect valuable data regarding sociodemographic characteristic of tobacco use, pattern of dependence among adolescent tobacco users, which will be essential for formulating recommendations, and their possible intervention aimed at reducing the problem of tobacco use. Methods: A community-based cross-sectional study was done where 400 subjects were enrolled. Nonprobability Snowball sampling technique was used to locate adolescents aged 12–18 years, who were practicing tobacco use. Face-to-face interviews were taken for data collection. Fragerstorm dependency test for tobacco was used to classify dependency of tobacco product into high and low dependency. Data was analyzed using Chi-square test and proportions using SPSS software version 21. Results: Majority of the subjects were in the age group of 16–18 years; mean age for initiation of tobacco was 15.6 years. Gutkha was the predominant form of tobacco product being used. Peer pressure 192 (48.0%) was the major reason for initiation of tobacco use. A significant association was found between dependency on tobacco and age, literacy, and socioeconomic status. Conclusions: Tobacco use starting from early age has many health implications. There is a need for stringent laws against the selling of tobacco to adolescents and targeted health awareness program against tobacco.

Background: Insomnia affects the daily activities of the sufferers and reduces attention and memory. Cognitive behavioral therapy is an expensive treatment and is not applicable to all patients, and long-term treatment with sleep medication can have side effects such as drug dependency. As an alternative form of non-pharmacological treatments, the effect of exercise therapy on improving the symptoms of insomnia is addressed in the current study. Methods: A total of 32 patients diagnosed with insomnia participated in the study, from which 16 received combined resistance-aerobic exercise therapy. The rest of the patients comprised the control group. The intervention group went through a 12-week intervention in the form of aerobic exercise for 3 days a week and resistance training for another 3 days a week. Patients' sleep quality was assessed by the Pittsburgh test before and after the intervention. Results: The results showed that combined aerobic-resistance exercise can improve sleep quality in patients with insomnia as well as increase subjective sleep quality and actual sleep duration, and decrease daytime dysfunction due to sleeping problems. Conclusions: This study shows that, along with other insomnia treatments, exercise can improve the sleep quality of patients.

COVID-19 pandemic, with its subsequent lockdown and mobility restriction is a public health emergency that has obliged substantial modifications in daily routines and lifestyle of people worldwide. The drastic measures of social isolation and home confinement has impacted to a great extent the physical and psychological health. The resultant abrupt in lifestyle-related behavior such as physical inactivity, unhealthy dietary habit, sleep disturbance, stress, tobacco use, and alcohol intake, is directly linked to the rising global burden of non-communicable disease. This review aims at gaining a rich and extensive understanding of the potential negative impact triggered by COVID-19 on lifestyle-related behaviors that will influence long-term physical and mental wellbeing. Electronic database search was conducted on PubMed, ScienceDirect, Google Scholar, and Scopus from January 1, 2020 to March 15, 2021. Data related to COVID-19 impact on lifestyle habits were extracted from these studies. Articles were included if meeting the inclusion criteria (i.e., assessed the impact of COVID-19 on physical inactivity and sedentary behavior, dietary habits, sleep, mental health, vitamin D, and substance use among adults. Further search was conducted to address these behavioral changes among athletes. While physical isolation is a necessary public health measure to protect the population, outcomes of this review indicate that in light of adverse lifestyle changes brought by the pandemic, noncommunicable disease remains a critical concern. Hence, adopting healthy lifestyle behavior is essentially important especially during the current time to boost immunity and reduce the risk of COVID-19 infection. Recognizing the pandemic collateral effects offers a forward-looking perspective to guide the government and health authorities in planning prevention and control programs that focus on resilient and sustainable behavioral change.

Background: Recently, several have evaluated the association between the components of the dietary inflammatory index (DII) score with the risk and severity of Coronavirus Disease 2019 (COVID-19). For the first time, we examined the association between DII^® with risk of coronavirus infection and symptom severity through a case-control study in Iran. Methods: The present case-control study was conducted on COVID-19 cases (n = 100) and healthy control (n = 100) volunteer, aged from 18 to 65 years. Dietary intake, DII, body mass index, COVID-19 infection, and the severity of its symptoms were assessed for each participant. A multivariable logistic regression analysis test was used to estimate the odds ratio and 95% confidence interval. Results: Our results demonstrated that COVID-19–infected patients were significantly older and had longer history of diabetes as compared to the healthy control group (P <.05). Furthermore, the participants with COVID-19 had a significantly greater intake of total fat (P =0.259), saturated fat (P =0.005), and dietary fiber (P = .004). In contrast, individuals in the healthy control group had a higher intake of carbohydrate (P = .005), sodium (P <.001), and iron (P <.001). However, there was no significant difference in DII score between COVID-19 and healthy controls (P =.259). In addition, we did not detect any specific association between DII score and risk of COVID-19 infection (odds ratio = 1.08, 95% confidence interval: 0.92 to 1.27; P =.294) and the severity of its symptoms (P >.05). Conclusions: There appears to be no specific association between DII score and risk of COVID-19 infection and the severity of its symptoms. More prospective cohort studies are necessary to confirm the veracity of our results.

Background: Globally and in Thailand, the incidence of colorectal cancer (CRC) is third-ranked behind lung and breast cancer, respectively. This hospital-based retrospective cohort study aimed to determine factors associated with mortality among patients with CRC. Methods: This study was performed by using the secondary data of the cancer registry among patients with CRC registered in Phatthalung Hospital. Two hundred twenty-eight patients with CRC were diagnosed and followed up from January 2014 to December 2018. Multiple logistic regression analysis was used to analyze factors associated with mortality among subjects with CRC. Results: The results revealed that the proportion of mortality among subjects with CRC was 50.44% (115 cases) at six months of following up. Subjects who had an increasing age every ten years (adjusted odds ratio [OR_adj] = 1.40, 95 percent confidence interval [95% CI]: 1.09–1.80) were diagnosed with CRC at stage 3 (2.64, 1.19–5.84) and at stage 4 (11.63, 2.69–50.15) more likely to die. Also, subjects who received a combination of chemotherapy and radiotherapy treatment (3.44, 1.20–9.85), combination treatment of surgery, and postoperative care (2.46, 1.22–4.94) were more likely to die. Subjects who had not had surgery treatment were more likely to die (35.00, 7.44–168.27). Conclusions: In conclusion, factors such as the age of patients, stage of CRC, and treatment were associated with mortality among patients with CRC. Hence, medical and health professionals should consider these factors according to the treatment and optimization in patients with CRC.

Background: Education of the patients with Coronavirus Disease 2019 (COVID-19) and their families is necessary to improve the quality of life. This study investigated the effect of person and family-centered training via telenursing on the quality of life in patients with COVID-19. Methods: This interventional study was performed on 88 patients with COVID-19 18--65 years and 44 family members referred to the Bank Melli Hospital, Tehran, Iran. The samples were randomly assigned into two groups person-centered and family centered. A cyberspace group including patients and their families was created. Four educational sessions planned (15--30-min-every day) and three sessions planned for completing the questionnaires via phone. The data were collected using demographic characteristics form and the 12-item Short-Form Health Survey version 2 before and 6 weeks after the intervention and were analyzed in SPSS 22 using Chi-square test, paired t-test, and independent t-test. Results: The mean scores of quality-of-life increased significantly in the person-centered group from 26.81 ± 5.15 to 34.4 ± 4.39 before and six weeks after intervention, respectively (p < 0.001). The means scores of quality-of-life increased significantly in the family-centered group from 28.11 ± 4.79 to 35.86 ± 3.85 before and 6 weeks after the intervention, respectively. (p < 0.001). Conclusions: The person and family centered methods increase the mean scores of quality-of-life of patients with COVID-19. The family centered method can be more effective to improve the quality of life of these patients.

Congenital hypothyroidism (CH) is one of the most treatable endocrine disorders in infants and children that can influence the function of many organs in the body. On-time diagnosis and treatment can prevent the adverse effects of thyroid hormone deficiency on the child's neurodevelopment. There are many challenges in screening, post-screening, diagnosis, and managing this disorder. Therefore, this article aimed to mention updated information on this issue. Although there are different approaches for the treatment of hypothyroidism, the authors decided to create a national approach based on the conditions of our country.

Background: Comprehensive assessment of health care quality is the first step in improving care and achieving health service goals. Therefore, this study aimed to conduct a systematic review and meta-analysis of health care quality in Iran based on the Comprehensive Quality Measurement in Health Care model. Methods: In this study, the databases of PubMed, Scopus, Web of Science, Iranian Scientific Information Database (SID), MagIran, and Google Scholar were searched using English and Iran keywords without time limit. STATA 16 software and a random effect model were used for conducting meta-analysis. Results: Of the 750 articles found, 20 were finally included; 13 of which were related to service quality, five to customer quality, and four to technical quality. Overall mean score of service quality was 7.79 [95% CI 7.43–8.15, df = 12, I² = 98.48, P value < 0.000] out of 10, and overall mean score of customer quality was 73.20 ± 4.56 [95% CI 65.18–81.22, df = 5, I² = 99.34, P value < 0.001] out of 100. Among the 12 dimensions of service quality, the confidentiality dimension (9.55 ± 0.12) had the highest mean score and the group support dimension (5.92 ± 0.901) had the lowest score. In general, from the viewpoint of service receivers, the technical quality is relatively favorable. Conclusions: According to the results of this study, the quality of health care in Iran is significantly far from ideal. Therefore, planning to improve providing health care is essential.

An epidemic of infectious diseases such as COVID-19 can affect mental health, which may be associated with suicidal behaviors. This study was conducted based on the systematic review and meta-analysis methods for evaluating the prevalence of suicide ideation during COVID-19. This study used Preferred Systematic Review Reporting System and Meta- Analysis guideline and valid keywords. The articles related to the prevalence of suicide ideation during COVID-19 pandemic were obtained by searching among different databases including Scopus, Web of science, PubMed, ISC, Google scholar, SID, and Magiran. All of the articles published from the beginning of January 2020 to the end of May 2021 were reviewed. Among 478 articles screened, 377 articles were related to the studied topic, among which 38 articles were selected after assessing the title and abstract of which for reviewing the full text and finally 18 studies were included in the meta-analysis. Based on the results, the prevalence of suicide ideation and attempt among all studies were equal to 13% (95% confidence interval = 0.11-0.15, I2 = 99.7%, P = 0.00) and 1% (95% confidence interval = 0.00-0.01, I2 = 95.5%, P = 0.00), respectively. Based on the results, the prevalence of suicide attempt and ideation is possible during the COVID-19 pandemic. Therefore, health officials should pay attention to mental health issues in addition to the protective measures for preventing or reducing the infection with COVID-19. The increase of psychological consequences is probably related to the effect of lifestyle changes which associates with the spread of the disease. In the current meta-analysis performed, the prevalence of suicidal ideation and suicidal attempt was examined during the COVID-19 pandemic period and compared to the previous period without COVID-19. The effect of COVID-19 on suicidal ideation and suicidal attempt has never been studied.

Background: Hearing loss is one of the most common congenital disorders. The Early Diagnosis and Intervention Process is designed for the early diagnosis and intervention of hearing loss in infants. The present study aimed to examine the results of Early Hearing Detection and Intervention (EHDI) in northeastern Iran from 2005 to 2019. Setting: Northeastern Iran. Methods: In most cases, the two-stage protocol (otoacoustic emissions [OAE] and automated auditory brainstem response [AABR]) has been used. Infant assessment methods included the use of OAE, ABR, auditory steady-state response, high-frequency tympanometry, and behavioral audiometry. Interventions included medical interventions, hearing rehabilitation, hearing aids, and cochlear implants. Results: 1,162,821 infants were screened. The screening coverage increased from less than 1% in 2005 to about 99% in 2018. The referral rate has been about 1%. 2.17 out of every 1000 infants are hearing impaired, and the most common cases are bilateral hearing loss and mild to moderate hearing loss. Conclusions: During 2005 to 2019 the coverage rate reached to more than 95% of live births. To improve the EHDI process in this population, better follow-up of diagnosed neonates and expansion of diagnostic and intervention services are needed.

Background: The household is considered as a private area that is untouched tobacco control policies in developing countries, especially in Indonesia, which has not ratified the Framework Convention on Tobacco Control (FCTC) treaty. Objectives: This study aims to identify smoking behavior and expenditure on cigarettes in the household, which are part of the initiation of a policy including a smoke-free home, so it assumes that the home is a public domain in Tegal Regency, Central Java Province, Indonesia. Methods: This research is an observational study with a quantitative descriptive design. A total of 225 subjects in the seven regions designated as smoke-free areas were all selected as samples in this study and were willing to be the subject of research. Results: The results found that 76.1% of smokers smoked with their nuclear family (wife/children/husband) present. Smoking behavior with the nuclear family inside the home (39.13%) and outside the home (36.96%) was more common than not smoking with the nuclear family. Expenditure for cigarettes per month was one-third of household revenue (IDR 607,521.74) based on the regency minimum wage (UMR) set by the local government. Conclusions: The study concludes that smokers who smoke with family still lack knowledge on smoking's impact on health and household economics. The smoke-free regulation that is initiated should include households as a parameter.

Background: The evolving COVID-19 outbreak requires a high level of population awareness and other measures to protect public health. Objectives: In this study, we aimed to identify knowledge, awareness, and fears of the Saudi population regarding COVID-19 during this pandemic. Methods: A cross-sectional survey study was conducted from April to May 2020 in different Saudi areas. Data were collected via online survey software (Google Forms), and the data collection tool was developed and validated by the study authors to fulfill the study objectives. Data were analyzed using SPSS version 21.0. Descriptive statistics and Chi-square tests were used for comparison between groups. The statistical significance was considered when the P value ≤0.05. Results: Study participants included 2982 people with 66.8% females. The average percentage of the awareness levels of the current study population was 68%. The vast majority (95.1%) did not know how the virus spread while 94.7% of the participants know the distance that a person should maintain from another person. Significantly higher percentages (70%) knew about and were aware of the prevention methods, including social distancing and hand hygiene, and 73.5% knew that elderly people with chronic diseases are the highest risk group to become infected. The highest significant fear of COVID-19 was from lack of treatment, which was reported by 77.5% of the participants with a P value of <0.05. Conclusions: Our study shows that the population has acceptable knowledge about COVID-19. Education and work-based awareness programs about COVID-19 are needed, especially for prevention and treatment aspects.

Background: Smoking is a public health problem that affects the adolescent population's health. This study aimed to investigate the relationship between extroversion (compared with introversion) and transition in cigarette and hookah smoking stages in high-school students to use the results in smoking prevention programs. Methods: A sample of 2312 students aged 15–16 years in Tabriz were included in the study. Demographic characteristics, cigarette, hookah smoking status, and Eysenck's extroversion questionnaires were completed by all students in the selected schools. Eight months later, cigarette and hookah smoking status were assessed again to determine transition in smoking stages. The marginal homogeneity (MH) test was used to compare the smoking status at the beginning and 8 months later. The generalized estimating equation (GEE) method with the ordinal link was applied to estimate the effect of extroversion on transition in smoking stages. Results: The mean (standard deviation) age of the students participating in the study was 15.5 (0.5) years. MH test results showed that, in general, transmission in the stages of both cigarette and hookah smoking in 8 months was significant in students (P-value < 0.0001). Extrovert personality had a significant positive effect on the transition from lower stages to higher cigarette and hookah smoking stages according to the GEE with ordinal link (P = 0.01). In cigarette and hookah smoking, extrovert persons transited to higher stages 1.64 and 1.55 times more than introvert persons. Conclusions: Being an extrovert person had a significant effect on the transitioning to higher stages of smoking cigarettes and hookah. In designing cognitive programs to prevent people from smoking or encourage them to quit smoking, considering this dimension of personality trait can be useful in the efficacy of the program.

Background: Disturbed biochemical factors have been observed in viral infections including SARS, Ebola virus, and now COVID-19. This study aimed to evaluate the association between Calcium axis' derangements and hospital duration, ICU admission, mechanical ventilation, and death in patients with COVID-19. Methods: 428 hospitalized patients with COVID-19 were included in this study. On the first day of admission, the patients were extensively evaluated for biochemical and hormonal factors and followed up until discharge/death. The association between hyperphosphatemia, hypoalbuminemia, and hypocalcemia and major outcomes, including hospital duration, ICU admission, mechanical ventilation, and death, was investigated by logistic regression analysis. Results: Hyperphosphatemia and hypoalbuminemia were present in 27 (6.3%) and 59 (13.8%) cases, respectively in the study population. The results of the present study reveal the relation of these factors with worse outcomes in COVID-19 patients; such as hospital duration, ICU admission, mechanical ventilation, and death. On the other hand, high frequency of hypocalcemia (59.1%, 253 subject) has no significant influence on the mentioned outcomes (All P values were greater than 0.05). Conclusions: Poor outcomes were associated with hyperphosphatemia and hypoalbuminemia. It seems that we should evaluate the patients for derangements of phosphate, albumin, and calcium and try to treat them for all COVID-19 patients.

Background: Kidney disorders are mainly diagnosed after a major decline in the renal function. Chronic kidney disease (CKD) is one of the most common disorders of the urinary system defined by gradual reduction of renal function. Considering the silent nature and late diagnosis of this problem, this study aims to investigate the prevalence of CKD and its association with Complete Blood Count (CBC) profile and liver function tests. Methods: Out of the total population enrolled in the Tabari cohort study, 5822 subjects without history of diabetes mellitus, hypertension, cardiac disease, renal failure, cancer, and pathologic obesity were selected. Glomerular filtration rate (GFR) was calculated using creatinine clearance as well as Modification of Diet in Renal Disease (MDRD) equation. CKD was defined as GFR decline less than 60 ml/min/1.73 m² regardless of its main cause. Results: Prevalence of CKD in total population as well as men and women was 20.2%, 16.8%, and 23.1%, respectively. Multivariate models showed the odds ratios for third and fourth quartiles of Mean corpuscular volume (MCV) and also for the fourth quartile of the lymphocyte count as of 0.78 (0.64, 0.95), 0.81 (0.67, 0.99), and 1.22 (1.01, 1.47), respectively. Corresponding odds ratios for the fourth, third, and second quartiles of Blood Urea Nitrogen (BUN) were 1.42 (1.14, 1.77), 1.76 (1.42, 2.19), and 2.79 (2.27, 3.43), respectively. Conclusions: This study showed a high prevalence of CKD among the normal residents (without major underlying diseases and excessive obesity) in the north of Iran, especially among women. In addition, low MCV, low lymphocyte, and high BUN were detected as predictors of this disorder.

Background: The present study aimed to investigate the effect of garlic supplementation on oxidative stress markers in patients with polycystic ovary syndrome (PCOS). Methods: Eighty patients with PCOS were randomized and instructed to consume either garlic supplementation (800 mg/day) or a placebo (starch) for 8 weeks. They were also asked to avoid intake of any other supplement during the study. Oxidative stress-related markers including total antioxidant capacity, catalase, glutathione, malondialdehyde concentrations, and anthropometric measures were assessed at baseline and end of the trial. Results: Garlic supplementation resulted in significant improvement in catalase concentration (1.82 ± 9.28 vs. –1.55 ± 8.66; P value: 0.03), glutathione levels (29.15 ± 57.53 vs. 2.42 ± 77.51; P value: 0.048) as well as weight (–0.64 ± 1.94 vs. 0.11 ± 0.82; P value: 0.04), body mass index (BMI; –0.25 ± 0.75 vs. 0.05 ± 0.61; P value: 0.04), and waist circumference (–0.21 ± 0.77 vs. 0.02 ± 0.65; P value: 0.01). However, we failed to detect any significant change in hip circumference, waist to hip circumference ratio, total antioxidant capacity, and malondialdehyde levels between the two groups. Conclusions: The present study indicates that garlic supplementation could be beneficial in improving oxidative stress and weight loss among PCOS women.

Background: Phototherapy is the most common form of treatment and prevention of neonatal nonconjugated hyperbilirubinemia. It seems that intravenous fluid therapy as a complementary method of phototherapy can accelerate the healing process in affected infants. This study aimed at investigating intravenous fluid therapy's effect in decreasing serum bilirubin in healthy term neonates with nonhemolytic hyperbilirubinemia under intensive phototherapy. Methods: As many as 160 healthy term infants with severe nonhemolytic hyperbilirubinemia and without exclusion criteria were enrolled. Infants were randomized to the two treatment groups (phototherapy alone and combination with intravenous fluid therapy). Serum bilirubin at admission time, 6, 12, 24, and 48 h later were measured. We evaluated decreasing serum bilirubin levels and duration of hospitalization in both groups. Results: In this study, the mean levels of serum bilirubin on admission time, 6, 12, 24, and 48 h after treatment gradually reduced in both groups; still, the decrease was not statistically significant between the two groups. Conclusions: Intravenous fluids therapy does not have a significant advantage in the process of phototherapy in healthy term neonates with severe nonhemolytic hyperbilirubinemia.

Background: Too much crying is a self-limiting problem and disappears within a few weeks. However, it can lead to maternal depression and parental stress. This study aimed to evaluate the effect of lavender oil inhalation on the duration of night crying within a week of intervention among infants with infantile colic. Methods: In this double-blind randomized clinical trial, the inclusion criteria for infants were being healthy, not taking any medications for colic, having an episode of crying two hours a day, and having a healthy mother. The intervention group received lavender oil inhalation and the control group received sweet almond oil inhalation for seven days. The data pertaining to the duration of crying were collected four times a day (morning, afternoon, evening, and night) via telephone contact. Mothers' mood scores were also assessed at the beginning of the study and on the seventh day of the intervention. Results: At first, the two groups were not different in terms of the duration of crying. After the intervention, however, a significant difference was observed in this regard on all seven days of the study (P < 0.001). Based on the results of the repeated measures analysis, the difference between the two groups was statistically significant (P < 0.001). Conclusions: The results showed that inhalation of lavender oil at low concentrations could reduce colic symptoms and improve maternal mood.

Background: According to World Health Organization (WHO), cardiovascular diseases (CVDs) are the leading cause of death globally. Although significant progress has been made in the diagnosis of CVDs, more investigation can be helpful. Therefore, this study aimed to predict the risk of myocardial infarction (MI) using data mining algorithms. Methods: The applied data were related to the admitted patients in Rajaei specialized cardiovascular hospital located in Tehran. At first, a literature review and interview with a cardiologist were conducted to understand MI. Then, data preparation (cleaning and normalizing the data) was performed. After all, different classification algorithms were applied in IBM SPSS Modeler (14.2) software on the prepared data; and, power of the applied algorithms and the importance of the risk factors in predicting the probability of getting involved with MI was calculated in the mentioned software. Results: This study was able to predict MI % 75.28 and 77.77% in terms of accuracy and sensitivity, respectively. The results also revealed that cigarette consumption, addiction, blood pressure, and cholesterol were the most important risk factors in predicting the probability of getting involved with MI, respectively. Conclusions: Predicting studies aim to support rather than replace clinical judgment. Our prediction models are not sufficiently accurate to supplant decision-making by physicians but have considerable tips about MI risk factors.

Background: Coronavirus disease 2019 (COVID-19) quickly spread to the world, causing a pandemic. While some studies have found no link between opioid use disorder (OUD) and COVID-19, the role of opioid on COVID-19 is challenging. The present study aimed to determine the relationship between OUD and COVID-19. Methods: This was a prospective cohort study. We used data from the third phase of the Shahroud Eye Cohort Study on 4394 participants which started in September 2019 and ended before the COVID-19 epidemic in Shahroud in February 2020. The participants were followed for about 13 months till March 26, 2021. COVID-19 was detected by RT-PCR on swap samples from the oropharynx and nasopharynx. The incidence of COVID-19 compared in OUD and non-OUD participants, and relative risk was calculated in log-binomial regression models. Results: Among the 4394 participants with a mean age of 61.1 years, 120 people had OUD. The incidence of COVID-19 in participants with OUD and non-OUD was 4.17% and 6.22%, respectively (P-value: 0356). The relative risk of OUD for COVID-19 was 0.60 (95% confidence intervals: 0.25–1.44; P value: 0.251). Conclusions: OUD was not associated with COVID-19. The claim that people with OUD are less likely to develop COVID-19 is not supported by these data.

The current pandemic coronavirus disease-19 (COVID-19) is still a global medical and economic emergency with over 244 million confirmed infections and over 4.95 million deaths by October 2021, in less than 2 years. Severe acute respiratory syndrome (SARS), the Middle East respiratory syndrome coronavirus (MERS), and COVID-19 are three recent coronavirus pandemics with major medical and economic implications. Currently, there is no effective treatment for these infections. One major pathological hallmark of these infections is the so-called 'cytokine storm,' which depicts an unregulated production of inflammatory cytokines inducing detrimental inflammation leading to organ injury and multiple organ failure including severe pulmonary, cardiovascular, and kidney failure in COVID-19. Several studies have suggested the potential of curcumin to inhibit the replication of some viruses similar to coronaviruses. Multiple experimental and clinical studies also reported the anti-inflammatory potential of curcumin in multiple infectious and inflammatory disorders. Thus, we hypothesized that curcumin may provide antiviral and anti-inflammatory effects for treating COVID-19. Although these studies suggest that curcumin could serve as an adjuvant treatment for COVID-19, its molecular mechanisms are still debated, especially its potential to modulate the toll-like receptors/TIR-domain-containing adapter-inducing interferon-β/nuclear factor kappa-light-chain-enhancer of activated B cells (TLR/TRIF/NF-κB) pathway. The preliminary results showed that curcumin modulates the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) pathway, a common pathway controlling cytokine production in multiple infectious and inflammatory disorders. Here, we hypothesize and discuss whether curcumin treatment may provide antiviral and anti-inflammatory clinical advantages for treating COVID-19 by modulating the TLR/TRIF/NF-κB pathway. We also review the current data on curcumin and discuss potential experimental and clinical studies that require defining its potential clinical implications in COVID-19.

Bakground: Ulcerative colitis (UC) is an inflammatory bowel disease that can be treated with many medications but they have various side effects and low cure rate. So, the need for finding novel drugs with better healing characters and less toxicity would be mandatory. Achillea millefolium (A. millefolium, Yarrow) has been traditionally used to treat bleeding, ulcers, wounds, liver, and bile disorders, and recently it has been shown to have anti-ulcer, analgesic, anti-inflammatory, antioxidant, and appetizing effects that make it as a good candidate for UC. Methods: UC was induced with intra-rectal instillation of acetic acid. A. millefolium hydroalcoholic extract (AMHE, 200, 400, and 600 mg/kg/day) and essential oil (AMEO, 62.5, 125, and 250 μl/kg/day) were given to six groups of male Wistar rats for 5 days. Dexamethasone (1 mg/kg/day, intra-peritoneal) and mesalazine (100 mg/kg/day, orally) were used as reference drugs. Colon tissue specimens were separated for assessing macroscopic, pathologic, and biochemical markers. Results: For AMHE, 77.2 mg/g equivalent to gallic acid was obtained for total phenols. Main assessed markers, including ulcer index, total colitis index, colon weight/length ratio, rats' weight gain, and malondialdehyde levels were significantly improved in AMHE (400 and 600 mg/kg/day) and AMEO (125 and 250 μl/kg/day) groups compared to controls. Myeloperoxidase activity was only attenuated in AMHE groups significantly. Conclusions: Both AMHE and AMEO were effective in healing experimental colitis. It seems antioxidant, anti-inflammatory, and anti-ulcer activities of Yarrow are responsible for these beneficial effects. Further studies are warranted to elucidate the exact mechanisms involved.

Background: Secondhand tobacco smoke exposure is one of the morbidity causes but it is ignored occasionally. Various studies have shown that hookah and cigarette smoke contain significant volume of heavy metals. This study was designed aiming biological monitoring of the level of heavy metals in the urine samples of workers in smoking cafés and its association with their lung function and respiratory symptoms in Tehran City. Methods: The list of cafés in Tehran was provided, and they were divided into water pipe cafés (WPC), cigarette smoking cafés (CSC), and non-smoking cafés (NSC); and then, 10 cafés were randomly selected from each group. Sampling was performed after explaining the study and obtaining the consent of the manager and staff. A check list of demographic data and smoking history was completed and analyzed. Results: A total of 96 individuals were studied; there were 32 subjects in each group. All subjects were male. Six days a week, they worked about 10 h a day in café. The concentration of heavy metals in the groups of hookah and cigarettes was significantly higher and respiratory indices in these groups were significantly lower than non-smoking group. Conclusions: Exposure to secondhand smoke increases the urinary level of heavy metals and reduces the respiratory capacity of people and this can be highly pathogenic in the future. Comprehensive informing on human rights should be provided in this regard and smoking bans in public places must be properly enforced.

Background: Perfectionism is a key construct for understanding psychopathology. In societies with varying cultures, studying the psychometric properties of tools can help with their external validity. This research aimed at standardization and validation of the Eating Disorder Inventory-Perfectionism (EDI-P) scale in Iran. Methods: The Persian version of EDI-P was formed through forward translation, reconciliation, and back translation. A total of 302 students were selected using convenience sampling method and' they completed a set of questionnaires, including the EDI-P, Weight Efficacy Lifestyle Questionnaire-Short Form (WEL-SF), Eating Attitude Test-16 (EAT-16), Self-esteem scale (SES), Difficulties in Emotion Regulation Scale-16 (DERS-16), and Self-compassion scale (SCS) Short Form. The construct validity of the EDI-P was assessed using confirmatory factor analysis and divergent and convergent validity. Internal consistency and test-retest reliability (2 weeks' interval) were applied to evaluate reliability. LISREL (version 8.8) and SSPS (version 22) software were used for data analysis purpose. Results: EDI-P scales and subscales were found to be a valid and reliable measure, with good internal consistency and good test-retest reliability in the nonclinical sample. Cronbach's alpha coefficient for the whole scale, socially prescribed, and self-oriented were found to be 0.74, 0.68, and 0.67, respectively. Test-retest reliability for the whole scale, socially prescribed, and self-oriented were found to be 0.88, 0.80, and 0.87, respectively. Convergent validity and divergent validity were good (Normed Fit Index [NFI] = 0.94, Incremental Fit Index = 0.95, root mean square error of approximation = 0.08, goodness of fit index = 0.97, Non-normed Fit Index [NNFI] = 0.91, and comparative fit index = 0.95). The results of this study provide support for the two-factor model of EDI-P. Conclusion: The EDI-P showed good validity and reliability and could be useful in assessing perfectionism in Iranian population. The EDI-P shows notable promise as a measure for use in eating research and clinical settings.

Background: Few studies have shown that smokers are more likely than non-smokers to have coronavirus disease 2019 (COVID-19), whereas some reports indicate that smokers are under-represented among those requiring hospital treatment for this illness. This study was designed and implemented for investigating the severity and outcome of COVID-19 based on smoking. Materials and Methods: This was a cross-sectional study implemented in Tehran and Ahvaz with all COVID-19 hospitalization patients from February to June 2021. Four categories selected for severity and worst outcomes. They are admission in the intensive care unit (ICU), lung involvement more than 50%, using more than three medications, and death. A check list of demographic data and smoking history was completed and analyzed. Results: A total of 11,112 patients were male (61.1%), and the mean age was 47.9 ± 11.3. A total of 1508 smokers (8.3%) were seen with any type of tobacco consumption. The frequency of ICU admission in the smokers is significantly higher than that in non-smokers (23.9% vs. 18.8%). A total of 668 (44.3%) smokers had more than 50% ground glass opacity in lungs, whereas 5340 non-smokers (32.1%) had so. Use of more than three medications in the smokers was significantly higher (70.6% vs. 52%). A comparison between patients based on smoking indicates that the death rate was significantly higher in smokers (31.6% vs. 25.6%). Conclusions: Although smoking rates in COVID-19 patients are lower than those in the general population, the consequences and mortality are higher in smokers.

This is a comprehensive review based on the published papers in the field of COVID-19 vaccines and vaccination. Many efforts have been made to develop vaccines to combat this pandemic. Since December 2020, more than 200 vaccines have been tested in various research stages and in clinical trials on humans, of which eight vaccines reached phase four clinical trials in humans and approved by FDA and EUA. After the Pfizer–BioNTech vaccine that had the highest efficacy (95%), the efficacy of the other vaccines are as follows: Moderna 94.5%, Sputnik V 91%, Novavax 89.7%, Sinopharm 79.3%, Oxford/AstraZenaca 70.4%, Johnson and Johnson 66.9%, and Sinovac 50.7%. At present, protein-based vaccines, with 35% of all available COVID-19 vaccines, are the most common technique in the vaccine production, and then there are vaccines of non-replicating viral vector (13.3%), mRNA1 (12.1%), DNA (10.2%), replicating viral vector (9.8%), and inactivated vaccines (8.2%). The most frequently recognized adverse effects within 7 days of each vaccine dose involved fever, fatigue, headache, chill, and myalgia. The mRNA-based vaccines were associated with a higher occurrence of local side effects (78.3 vs. 70.4%; Sig. = 0.064), whereas the viral vector-based vaccine was associated with a higher prevalence of systemic side effects (87.2 vs. 61%; Sig. < 0.001). Based on the evidence and articles in the field of vaccination, AstraZeneca-Oxford and Sinopharm vaccines reported the highest and lowest side effects, respectively. Because of being emerging, pathogenicity, and high infectivity of COVID-19, vaccination against the disease to prevent its incident rate and decrease the prevalence rate is recommended immediately. Being informed of various aspects of the existing vaccines such as efficacy, effectiveness, safety, etc.can accelerate to make effective and useful choices and consequently have a vaccinated community against the epidemic.

Background: Congenital anomalies are among the causes of disability and death in infants. This study aimed to determine the incidence of major congenital anomalies (MCA) recorded at birth and also their relationship with some related factors in neonates born. Methods: In this cross-sectional study, all infants born from March 2016 to March 2017 in the hospitals of Chaharmahal and Bakhtiari Province were evaluated for MCA at birth. Information recorded in the medical file including parent and infant characteristics is extracted from the maternal and newborn electronic files. Data were analyzed using Generalized Linear Model with function of Poisson. Results: Of the 19666 newborns studied, 63 (3.2 per 1000) had MCAs at birth. Variables such as number of pregnancies, parity, gestational age, neonatal birth weight, height, and head circumference were found to be significantly associated with MCA based on the crude model (P value < 0.05). Using adjusted model 1, the incidence of MCA was found to be significantly related to mother's place of residency and her parity. Finally, in adjusted model 2, the incidence of MCA was found to be related to gestational age, neonatal birth weight, and head circumference. Conclusions: In some MCA, early diagnosis and treatment can prevent disability. Consequently, the emphasis on public education to consider appropriate gestational age, proper nutrition before and during pregnancy, and prenatal care is necessary to inhibit MCA.

Background: The objective of this research is to consider the incidence of brain cancers in Iran during the years 2004–2008 to improve reporting, distribution of the disease. Methods: In this cross-section study, the study population was all brain cancer cases diagnosed in Iran between 2004 and 2008. Age-standardized rate (ASR) per 100,000 persons and crude rate were calculated using direct standardization. Data were analyzed using Statistical Package for the Social Sciences (SPSS version 16) and Microsoft Office Excel 2010. Results: During the period 2004–2008, the ASR and crude rate of brain cancers among males were 2.37, 2.46, 2.77, 2.84, 4.16 and 2.13, 2.11, 2.40, 2.49, 3.61, respectively, and among females the ASR and crude rates were (1.64, 1.67, 2.04, 2.17, 3.09) and (1.45, 1.45, 1.76, 1.84, 2.62), respectively. Conclusions: According to the study results, a significant increase in the incidence of brain cancer was observed over a 4-year period in Iran. Hence, screening and early detection programs for this type of cancer are highly recommended.

Background: There has recently been a high increase in the prevalence of adolescent pregnancies, especially in developing countries, because they are considered vulnerable populations. The objective of this study was to determine the risk factors for low emotional intelligence and for depression in pregnant Peruvian Andean adolescents seen in a public health centre. Methods: The study was a correlational analysis of 280 pregnant Peruvian Andean adolescents using logistic regression analysis. Emotional intelligence and depression were considered dependent variables, while independent variables were age, marital status, and education. The instruments used were Beck's Depression Inventory and the BarOn Emotional Quotient Inventory: Youth version. The threshold of significance was P < 0.05. Results: Age, marital status, and level of education were not risk factors for lower emotional intelligence, because they had respective ORs of 0.8 (95% CI: 0.5-1.4), 1.6 (95% CI: 0.8-3.4), and 0.7 (95% CI: 0.0-1.1). Nor were they risk factors for depression, showing ORs of 0.8 (95% CI: 0.4-1.5), 0.6 (95% CI: 0.2-1.3), and 0.6 (95% CI: 0.3-1.1), respectively. Conclusions: Thus, the risk factors studied do not significantly influence emotional intelligence or depression in pregnant Peruvian Andean adolescents.

Background: Breast cancer is the most common cancer in the world, which accounts for 21.4% of all kinds of cancers for women in Iran. However, the treatment of breast cancer is costly and given that the budget devoted to the healthcare sector is limited, the present study aimed to investigate the cost-effectiveness of breast cancer screening for women, who referred to breast clinic located in Shahid Motahari clinic affiliated to Shiraz University of Medical Sciences, Shiraz city, Iran in 2017-2018. Methods: This study is a cross-sectional study analyzing the cost-effectiveness of breast cancer screening versus no screening. The study was conducted on 3500 women, who referred to the breast clinic in Motahari clinic, at 2017–2018 in Shiraz, Iran. The patients were identified and direct costs, which were correlated to cancer breast screening, were calculated based on the patients' records with public tariff per person. Tree age pro 2011 used to analyze cost effectiveness. Results: Based on the results obtained, the expected cost of screening and no screening were 7556 $ppp and 7840 $ppp, respectively. Given their difference in effectiveness (16%), screening was dominant (less costly and more effective) compared to no screening. Tornado diagram showed that the results had the maximum sensitivity to the increase in screening cost. Conclusions: In general, according to the results obtained from the current study, the screening was more cost effective compared with no screening.

Background: Although previous studies have described a positive correlation between physical activity and 25-hydroxyvitamin D levels (25(OH)D), the relationship between participation in school sports and 25(OH)D levels among children has not been well characterized. Methods: The present study analyzed data from participants aged 5 to 15 years in the National Health and Nutrition Examination Survey cycle 2013-2014. General linear models adjusted for potential confounders were assembled to examine 25(OH)D levels according to participation in school sports. Results: Of 1,670 children in the study sample, 17.9% were defined as having 25(OH)D inadequacy (< 50 nmol/L). Overall, 38% of children reported participation in school sports. In general, 25(OH)D levels were increased among children examined between May 1^st and Oct 31^st non-Hispanic whites, normal weight, higher income, and daily vitamin D intake ≥ 400 IU/d. After adjusting for potential confounders, 25(OH)D levels were 3.7 nmol/L higher among children who played in any school sports than those who did not. In general, higher 25(OH)D levels were seen among children examined during summer and fall seasons than those during winter and spring seasons, regardless the type of sport activities. Moreover, children who played mixed sports during summer and fall seasons had significantly higher 25(OH)D levels than their physically inactive counterparts. Conclusions: 25(OH)D concentrations were significantly higher in children playing school sports than those who did not. Thus, children's participation in school sports, particularly during summer and fall seasons should be considered as an effective public health intervention to reach optimal 25(OH)D levels.

Background: Type 2 Diabetes Mellitus (T2DM) is the prominent public health issue. Pharmacotherapy and diet modification should be integrated into T2DM management. Aims: To investigate the effects of vegetables consumption before carbohydrates on blood glucose and GLP-1 levels in T2DM patients. Methods: A non-randomized quasi experimental study was conducted to recruit T2DM patients who attended at the Gatot Soebroto Central Army Hospital, Jakarta, Indonesia from April to May 2016. The Lemeshow's formula was used to determine sample size. A total of 12 non-diabetic and 24 diabetic patients were participated in our study. Glucose levels were measured using a routine hexokinase method while serum GLP-1 levels were determined using the ELISA. The student t-test was used to compare two groups with parametric data. The significant difference was at P < 0.05. Results: Our data showed that T2DM patients who consumed vegetables before carbohydrates, had relatively stable glucose levels at 0, 60 and 120 mins (164.25 ± 86.89 vs 183.5 ± 55.96 vs 167.83 ± 65.53, P = 0.163) and stay lowered within the normal range compared to T2DM patients who consumed vegetables after carbohydrates (165.08 ± 67.89 vs 241.92 ± 68.03 vs 204.92 ± 81.76, P = 0.022). Additionally, GLP-1 levels remained stable after 60 and 120 min at day 1 (P = 0.816) and day 3 (P = 0.955). Conclusions: Vegetables consumption before carbohydrate is a promising and simple method of diabetes diet for maintaining blood glucose and GLP-1 levels and preventing from vascular complication.

Backround: Noise is one of the most important occupational and environmental health hazards. Exposure to loud noise can cause irrevocable hearing damage and loss of hearing. The aim of this study was to determine the efficiency of two samples of earmuff and earplug in low frequency noise reduction in comparison to subjective method. Methods: All the procedures of the work were done using the simulated human ear canal and the required microphone in the eardrum. At the octave frequencies, that is 31.5 and 63.5, 125, 250, 500, 1000, 2000, 4000, and 8000 Hz, and intensities of 85-90 dB, one stage was done by using the individual's subjective response relative to the received sound before and after using the ear protector. Results: The sound levels before and after the protection were significantly different in both the model and humans (P < 0.05). However, at 315 Hz frequency, the rate of attenuation is increased by 4 dB after placing the earplug and 14 dB after placing the earmuff, showing a reduction of 18 dB. Conclusions: This study verifies the increasing protection by simultaneous application of earplugs and earmuffs. Because of the laboratory evaluation of ear protectors, it is possible not to justify the proficiency of ear protectors in a subjective method.

Background: This meta-analysis was performed to investigate the effect of serum lipids on the risk of breast cancer incidence. Methods: PubMed, Web of Science, Scopus, and EMBASE were searched systematically from January 1998 to April 2019. Inclusion criteria were English observational studies (cohort or case-control) and the concentration of at least one of the lipid profile components (total cholesterol/triglycerides/low-density lipoprotein cholesterol/high-density lipoprotein cholesterol) measured before a diagnosis of breast cancer (BC). The studies were included in which the relative risk (RR) had been reported with 95% confidence intervals (CIs). A random-effects model was used. Results: A total of 25 studies were found, including 2,882,789 participants in cohort studies with 45,481 cases with BC, and 1983 BC cases and 2963 case-control studies. Combined RR of cohort studies for the highest versus lowest for the BC was LDL-C: 0.95 (95% CI: 0.89–1.01), triglycerides (TG): 0.95 (95% CI: 0.91–0.99; P = 0.02), total cholesterol (TC): 0.98 (95% CI: 0.91–1.05), and HDL-C: 0.86 (95% CI: 0.63–1.18). Combined RR of case-control studies for the highest versus lowest was LDL-C: 1.08 (95% CI: 0.78–1.48), TG: 1.73 (95% CI: 0.94–3.18), TC: 1.02 (95% CI: 0.80–1.29), and HDL-C: 0.79 (95% CI: 0.65–0.97). Conclusions: Based on the results, it can be concluded that only TG but not TC and/or LDL-C had a significant inverse association with the risk of BC incidence. HDL-C showed a significant protective effect against breast cancer in postmenopausal women and case-control studies.

Background: The first need of any society is to have a healthy life that can be achieved through preventive education. Despite providing training in the prevention of risk factors for noncommunicable diseases in the country's educational programs, we are witnessing an increase in the incidence of these diseases. We aimed to summarize the views of experts in the field of health and education on improving the effectiveness of these trainings. Methods: This study was conducted with a qualitative approach and conventional content analysis method. Participants were 12 experts in the field of health and 19 employees in education who were selected by purposive and available sampling method with maximum diversity. The data collection method was semistructured interview with note-taking. Results: A total of 32 subcategories and 9 main categories were extracted: “Macro health policies,” “Strategic health system,” “The role of education system in health promotion,” “Schools and Lifestyle modification,” “Informal learning,” “Preventive strategies in promoting health,” “ Lifestyle, multifactorial phenomena,” “The impact of stress on health,” and “Factors affecting preventive education.” Conclusions: Providing preventive education to students is one of the ways to prevent noncommunicable diseases. If these trainings have the necessary attractiveness and support by the authorities (and especially the health system), then it will not only raise students' awareness, but also change their attitude and improve their performance.

Background: The role of anti-phospholipid antibodies (aPLs) in the prognosis of COVID-19 patients is controversial. In order to prove the role of this factor, the necessary measures such as early initiation of anticoagulants should be started even in the early stages of the disease and in outpatients or the use of other drugs in addition to anticoagulants. We decided to investigate the role of these antibodies in ICU admission outcomes in critically ill COVID-19 patients. Methods: The case-control study was carried out in Isfahan, Iran, from March to September 2021. One hundred nine patients in the case group were selected, including patients admitted to the ICU with a COVID-19 diagnosis. The 140 patients in the control group were selected from hospitalized and outpatients with COVID-19 with PCR + and pulmonary involvement, similar to the case group without the need for ICU hospitalization. The anti B2GP1 (IgM, IgG) and anti-cardiolipin (IgM, IgG)) were compared in two groups. Results: The frequency percentage of patients in the abnormal group of anti-phospholipid antibodies was about 10% in total. No statistically significant difference in these aPLs in continued measures was observed between the two groups of patients admitted to the ICU and those outside the ICU. Also, in the logistics regression analysis, no significant association was observed. Conclusions: Therefore, the cause of coagulation in patients admitted to the ICU is not related to these aPLs. This means that aPLs could not be a good predictor of patient admission to the ICU.

Background: Some circulating microRNAs, such as miR15b, are predictors of diseases associated with adulthood obesity. This study aimed to evaluate the effect of two selected school-based and high-intensity interval training (HIT) on miR15b expression and lipid profile of obese adolescents. Methods: Thirty-eight adolescent males (12 ± 1 years) with obesity (body mass: 74.7 ± 13.2 kg, body mass index (BMI): 26.0 ± 2.3 kg/m², and body fat (BF): 27.2 ± 3.6%) were randomly assigned to the following based on the age-related body mass index: (i) HIT (n = 13), (ii) school-based exercises (SBE, n = 13), and (iii) control (n = 12) groups. Mir15b was extracted using the RT-PCR system, and lipid profile was studied using the enzymatic colorimetric method before and after 12 weeks. Three training sessions were held each week during the course. Results: Following the exercise interventions, in both training groups, miR15b (HIT: –63.8 vs. SBE: –56. 7%; P = 0.001), cholesterol (HIT: –8.8 vs. SBE: –9.2%; P = 0.025), and low-density lipoproteins levels (SBE: –13.1 vs. –20.8%; P = 0.48) decreased; however, the peak oxygen uptake of subjects increased (HIT: 4.0 vs. SBE: 4.0%; P = 0.003). However, there were no significant differences in triglyceride (HIT: –16.9 vs. SBE: –8.3%; P = 0.134), and high-density lipoprotein (HIT: 3.1 vs. SBE: 4.8%; P = 0.479) levels between both intervention and control groups (P > 0.05). Conclusions: The results showed that both types of exercises had almost similar effects on reducing miR15b expression and improving the lipid profile. Hence, based on the difficult nature of HIT for children with obesity, further use of school-based exercises is suggested.

Background: Malnutrition is a major public health issue worldwide. It has significant consequences, including weakened immune systems, which may lead to increased incidences of infectious disease and higher mortality, particularly in children. A systematic review and meta-analysis were conducted to estimate the overall prevalence of malnutrition (wasting, underweight, and stunting) among children of 6–14 years of age in Iran. Methods: Data were collected in 2018 based on searches of the PubMed, Science Direct, Scopus, Google Scholar, Science Information Database (SID), Magiran, Irandoc, and Iranmedex databases using the following keywords: childhood, childhood malnutrition, children, nutrition, malnutrition, wasting, underweight, stunting, child, student, boy, girl, cause, prevalence, and Iran, in order to identify studies eligible for inclusion in the review. Comprehensive Meta-Analysis, version 2 (CMA: 2) was used to estimate the overall prevalence of malnutrition. Results: Nine out of 328 articles were included in our analyses. The overall of wasting among children of 6–14 years of age in Iran based on the random-effects model (according to nine studies and 18,296 participants) was 12.5% (95% Confidence Interval, 7.1-21.2). The overall prevalence of underweight based on the random-effects model (according to 10 studies and 19,185 participants) was 19% (95% CI, 8.1-38.6). Also, the overall prevalence of stunting based on the random-effects model (according to 10 studies and 19,185 participants) was 20% (95% CI, 9.4-37.8). Conclusions: The results of this study show that the prevalence of malnutrition among 6–14-year-old children in Iran is similar to the global average. We need solutions that can be used for both prevention and reduction of malnutrition, especially in areas with middle or low socioeconomic status. It is necessary to identify factors associated with malnutrition in various geographic regions in order to implement appropriate programs based on factors with the highest impact in each region.

Background: One billion worldwide population is living in slum areas that mostly accompanied with high rates of poverty, illiteracy, unemployment, unhealthy situation, and inappropriate health-care services. The prediction of enormous growth of slums by 2030 led to a raise to address the “plight of slums” in Sustainable Development Goals (SDGs). Methods: To address evidence-based health-related priorities, we conducted a systematic review to summarizing evidences on health situations of slums population in Iran. Six electronic databases were systematically searched for published studies without any restriction on age, sex, and language to assess health situations of slums in Iran reported by following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. All identified articles were screened, quality assessed, and data extracted by two authors independently. Results: The finding of this systematic review in addition to overall view categorized in five categories: health system, reproductive health, infectious diseases, noncommunicable diseases and their risk factors, social issues besides overall situation of Slums. Conclusions: Community-based participatory interventions with socioeconomic approach on modifiable risk factors; active response of health system; establishment new health care centers in slum areas; augmenting the quality of care; active case finding; and elevating health knowledge, attitude, and practice is crucial to achieve SDG's in Slum area.

Background: Obesity is a chronic medical illness with a higher risk of physical and mental cascade. People who seek obesity treatment were reported to have some psychiatric disorders affecting their disease and selection of management. Aims of the Study: This study aims to estimate the prevalence of depressive and anxiety disorders in obese patients seeking obesity management and explore the relationship between common psychiatric disorders (depression and anxiety disorders) and selection of the type of obesity management (surgical or non-surgical). Methods: Patients were recruited from Alazhar Universityhospitals,Egypt, and the total number completing the study was 1115 patients. All subjects underwent psychiatric interview through Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID-5 for DSM-5) for diagnosis of psychiatric disorders and completed two questionnaires, Hamilton Rating Scale for Depression (HRSD) and Hamilton Rating Scale for Anxiety (HRSA). Results: The prevalences of depressive and anxiety disorders were 29.23% and 25.56%, respectively, in all subjects. The most prevalent diagnoses were dysthymic disorder (20.7%), general anxiety disorder (16.95%), major depressive disorder (13.04%), and social phobia (12.4%). Our sample was divided into two groups (surgical and non-surgical). Dysthymia was more common in the surgical group (21.4% versus 19.8% P = 0.560), whereas major depressive disorder was more common in the non-surgical group (7.4% versus 5.4 P = 0.593); also, the non-surgical group was more likely to have “anxiety disorders” (29.23% versus 22.4%, P = 0.840), but severity of anxiety was higher in the surgical group according to HRSA score with a highly significant difference. Conclusions: A high prevalence of depression and anxiety disorders was found among patients who sought obesity treatment. Severity of anxiety was higher in the surgical group according to HRSA score with a highly significant difference, which may affect selection of treatment, so psychiatric evaluation and management are needed before and after obesity management to improve the outcome.

Background: Colorectal cancer (CRC) is the third most common cancer among adults in Iran. The aim of colorectal cancer screening is to reduce the cancer burden in the population by diagnosing the disease in its early stages. Methods: We adapted this guideline for the moderate CRC risk population for Isfahan to determine how to screen them and when to start and end the CRC screening. This guideline was developed by clinical appraisal and review of the evidence, available clinical guidelines, and in consultation with members of the Isfahan Chamber of Iranian association of gastroenterology and hepatology. Results: In screening people with average risk for CRC who use personal resources and personally pay all the costs, colonoscopy is recommended as the first choice to be done every 10 years. In case of negative colonoscopy, we recommend FIT test to prevention of interval cancer every 5 years. In screening of people with average risk of CRC, FIT is suggested to be done every 2 years as a first-choice method test for those who use public resources and do not pay for this service personally. In screening individuals with average risk for CRC, g-FOBT is not recommended as the first method of choice. Repeating positive guaiac test is not recommended and if positive, colonoscopy is suggested.

Introduction: Considering the key role of physicians in providing genetic counseling services and the lack of studies in this field in Iran, it seems necessary to design a valid and reliable instrument for measuring the awareness, attitude, and performance of general and specialist physicians in genetic counseling. Materials and methods: In this descriptive study, the design and psychometrics of the questionnaire were performed in 4 steps: first, defining the concept of awareness, attitude, and performance of general and specialist physicians in relation to genetic counseling by reviewing texts and articles; second, designing questionnaire items; third, determining the face and content validity by 10 university experts; and forth, determining reliability using Cronbach's alpha coefficient method. Results: The primary version of the questionnaire was designed taking into account 60 items during the first and second stages. In the third step, one item was removed and in the final version of the questionnaire 59 items and the content validity index (CVI) and content validity ratio (CVR) were reported to be 0.98 and 0.92, respectively. Reliability with Cronbach's alpha coefficient was determined 0.82. Conclusion: The final questionnaire with 59 items had appropriate psychometric properties. This questionnaire has the ability to be used by health care providers in health care systems to measure the awareness, attitude, and performance of physicians about genetic counseling. The need for further studies is suggested to measure the other types of validity, such as the structural validity of the questionnaire.

Background: These days, silver nanoparticles (Ag NPs) have been given considerable attention and applied in medical technology due to their great antimicrobial and antioxidant features. In the present study, we aimed to synthesize Ag NPs through the reduction of silver nitrate in the presence of Vitex agnus castus L fruit extract. Methods: After collecting fruits, their extract was prepared and added to Ag NO₃ to produce Ag NPs. The effect of different parameters like AgNO3 concentration (0.5, 1, 3, and 5 mM), sunlight exposure, and sunlight irradiation time (10, 20, 30, and 40 min) was investigated in the synthesis of Ag NPs. The features of Ag NPs were characterized using UV-visible spectroscopy, scanning electron microscope (SEM), X-ray diffraction (XRD) analysis, and dynamic light scattering analysis. Moreover, antimicrobial function of Ag NPs was evaluated using Escherichia coli and Bacillus cereus bacteria species and minimal inhibitory concentration (MIC) of Ag NPs against these two pathogens was measured. Results: The results showed that the synthesized nanoparticles had a spherical shape and the range size of 30-60 nm. For the first time, the antimicrobial activity of synthesized Ag NPs of Vitex agnus castus L fruit extract was shown. Conclusions: It can be stated that the biosynthesis of Ag NPs using fruit extract of this plant is an environmentally friendly, economic and harmless method without any use of poisonous substances and no side effects. These Ag NPs can be considered as suitable antibacterial agents and replacements for antibiotics.

Background: Choosing the right temperature probe location is important, especially in VLBW infants. We aimed to determine five points of the skin surface and compare them with the axillary temperature of potentially suitable locations as well as the best location for skin probe placement. Methods: In a cross-sectional study, 400 neonates with gestational age above 26 weeks were enrolled. The axillary temperature was measured using a mercury thermometer at 0 and 30 min. Then, the body temperature was measured using a surface probe on the five skin areas, including the thoracic area, epigastric region, RUQ area, hypogastric area, and left flanking area. Data recorded were compared with the axillary temperature at 0 and 30 min. Results: Mean neonatal axillary temperatures at 0 and 30 min were 36.60 and 36.61, respectively. The mean temperature was recorded using skin probes at 0 and 30 min in the thoracic region (36.34 and 36.35) in the epigastric region (36.45 and 36.47), in the RUQ region (36.50 and 36.52), in the Flank region (36.26 and 36.20), and in the hypogastric region (36.24 and 36.26). The lowest mean difference recorded by surface probes with the temperature measured by the thermometer in the axillary region was related to the surface probe RUQ (mean difference: 0.1 and 0.09), which was not statistically significant. Conclusions: RUQ area probe has the lowest difference with the temperature calculated using the thermometer in the axillary region and is the best place to put the skin probe for prevention of hypo/hyperthermia.

Background: Infectious diseases are one of the most important problems that affect the whole world. The World Health Organization (WHO), an active health organization, has identified coronavirus disease 19 (COVID-19) as a public health emergency and advises governments not to waste time on effective measures and interventions to attack and suppress the virus. In Iran, so far, the total number of screening tests has exceeded 21 million tests and more than 5 million doses of vaccine have been injected. However, we are still far from controlling the epidemic wave. Given the current situation, it is necessary to identify the challenges of managing the new coronavirus epidemic (COVID-19) in the country's medical universities. Methods: This qualitative study was conducted from January 2020 to January 2021 to explore the views of a group of service providers and staff managers of medical universities who were selected via purposeful sampling (n = 47). Data were collected through semi-structured interviews and analyzed using Graneheim and Lundman's conventional content analysis methods. The trial version of MAXQDA 16 software was used to manage the coding process. Results: Upon analysis of data by service providers and staff managers of medical universities, five main themes including governance and leadership, service delivery, human resources, medicine and technology, and financing and 15 sub-themes including management and leadership, culture and society, process, infrastructure, manpower, training and skills, mental pressure, work pressure, nutrition, safety, employee motivation, medical equipment, medicine, payment, and funds were found. Conclusions: Identification of the most important challenges of service providers and staff managers can play an important role in improving the management of the new coronavirus epidemic (COVID-19). It seems that in order to solve some of these challenges, coordination is needed outside the field of health, and considering the formation of the National Corona Headquarters at the national level, it is possible to use this infrastructure to provide the necessary policies and strategies.

Background: In the name of extensive vaccine uptake, understanding the public's attitude, perception, and intent toward COVID-19 vaccination is a significant challenge for public health officials. Methods: A cross-sectional survey via an online questionnaire rooted in the Health Belief Model and Integrated Behavioral Model was conducted to evaluate COVID-19 vaccination intent and its associated factors. Factor analysis and multivariate logistic regression were operated to be satisfactory. Results: Among the 4,933 respondents, 24.7% were health care workers, and 64.2% intended to accept COVID-19 vaccination. The adjusted odds (aOR) of COVID-19 vaccination intent was higher for individuals with greater exposure to social norms supportive of COVID-19 vaccination (aOR = 3.07, 95% Confidence Interval (CI) = 2.71, 3.47) and higher perceived benefits of COVID-19 vaccination (aOR = 2.9, 95% CI = 2.49, 3.38). The adjusted odds of vaccination intent were lower for individuals with greater COVID-19 vaccine safety concerns (aOR = 0.28, 95%CI = 0.25, 0.31). Lower vaccination intent was also associated with increasing age ((aOR = 0.99, 95% CI = 0.98, 0.999), female sex (aOR = 0.76, 95% CI = 0.65, 0.88), and working in the health care field (aOR = 0.75, 95% CI = 0.63, 0.9). Conclusions: The odds of COVID-19 vaccination intent were higher three or more times among those with a greater belief in vaccine effectiveness, lower concerns about vaccine safety, and greater exposure to cues to vaccinate, including from doctors. This last finding is concerning as vaccine acceptance was surprisingly lower among health care workers compared to others. The remarkable results of factor analysis and reliability of the questionnaire may encourage local health authorities to apply it to their regional population.

Background: To assess the psychological consequences of changes during the coronavirus 2019 (COVID-19) pandemic in the Iranian population. Methods: We performed an anonymous online survey in the first 3 weeks of March 2020. Individuals older than 14 who could read Persian, and lived in Iran, were eligible for the study. The participants had to rate their stress levels and depressive symptoms (using a nine-item Patient Health Questionnaire PHQ-9) during the last 2 weeks and before the pandemic retrospectively. The changes in the psychological measurements and their association with the sociodemographic factors and burdens due to confinement were assessed. Results: Overall, among the 3,210 subjects who participated in our study, both the stress levels and average depression scores increased. However, about 23% of the subjects reported a decrease in their stress levels. The burden of childcare, restrictions in private life, and thoughts about the future were positively correlated with the changes in the stress levels and depression scores (,r,> 0.15). However, feeling relieved in the pandemic condition, and enjoying more family time were associated with less change in the stress and depression scores. Being religious (odds ratio [OR] [CI]: 1.5 [1.3-1-8]) and older age (OR [CI]: 2.9 [1.8–4.6] for >55 years old) were identified as the resilience factors, whereas being a student (OR [CI]: 2.1 [1.6;2.7]), seeking a job (OR [CI]: 2.6 [1.8;3.9]), and history of a psychiatric disorder (OR [CI]: 3.2 [2.6;4]) were identified as the risk factors for depression. Conclusions: The stress levels and depressive symptoms have increased during the COVID-19 pandemic and this increase is related to different social and personal burdens due to the confinement conditions.

Background: Waterpipe smoking is associated with maternal and fetal complications, and valid data contribute to evidence-based planning. This study was conducted to determine the prevalence and factors related with waterpipe smoking among pregnant women of Zahedan city in 2020. Methods: This cross-sectional study was conducted in 2020, and 400 pregnant women in the third trimester of pregnancy who lived in Zahedan participated in it by single stage randomized cluster sampling. A questionnaire was used to measure awareness of waterpipe complications, and another one investigated the status of waterpipe smoking to collect data. For data analysis, descriptive statistics and multiple logistic regression were used through SPSS 21. Results: The findings indicated that the prevalence of waterpipe smoking was 18.8%. In the waterpipe smoking group, 46.6% smoked every day, 89.3% had tried to reduce the smoking, and 64.8% reported fetal death as their main motivation to reduce smoking. Only 5.6% of subjects stated receiving training as the reason for reduction of their waterpipe smoking. The women's level of education, economic status, ethnicity, and awareness of the risks of waterpipe smoking were the predictors for waterpipe smoking (P < 0.05, P = 0.03, P = 0.006, and P < 0.001, respectively). Conclusions: The results of this study show the high prevalence of waterpipe smoking in pregnant women of Zahedan. Further investigation and training in this regard are essential for pregnancy as well as pre-pregnancy care. Special attention should be paid to groups with better economic status and level of education, Baluch women, and those with low level of awareness.

Background: The overuse and abuse of the Internet incur the risk of Internet addiction. Besides, as adolescents spend many hours on the Internet, their general health is at stake. Methods: The present study was a descriptive cross-sectional study. The study sample included 1000 female and male high school students in Bushehr City in 2018. The students took part in this study by completing Kimberly Young's Internet Addiction Test (IAT) and Goldenberg's Mental Health Questionnaire. The frequency, mean, and standard deviation measures were also used to explain the results, and data analysis was performed using the Chi-squared tests technique, which was also used to analyze the data and to examine the relationship among mental health and Internet addiction and logistical regression. Results: According to the results of the prevalence of Internet addiction it was found that 1.1% (10 individuals) were Internet-addicted and 33.1% (299 individuals) were at the risk of Internet addiction. The findings of this study indicated that four different areas of mental health including physical condition, anxiety, depression, and social functioning have a direct relationship with Internet addiction (P < 0.05). Conclusions: In the present study, a large percentage of the students were prone to Internet addiction. Hence, it is necessary to plan and perform preventive, controlling, and interventional measures for high school students.

Coronavirus disease-19 (COVID-19) caused by SARS-CoV-2 is a novel viral infectious disease, which broke out in the end of winter season 2019 in China and soon became a pandemic. Characteristically there was severe local and systemic immune-inflammatory response to the virus, damaging the respiratory system and other organ systems. The morbidity and mortality caused by the disease are producing tremendous impact on health. The understanding about pathogenesis and manifestations of the disease was obscure. To date, no classic treatment or preventive measure was available for COVID-19 other than symptomatic and supportive care or few drugs under trial. A possibility exists that maintaining vitamin A adequate levels can protect the affected respiratory mucosa, increase antimicrobial activity, produce better antibody response, and have antiinflammatory effects, thereby promoting repair and healing as well. It has been discussed in the review that by various mechanisms, immune regulation through vitamin A supplementation is beneficial to boost immunity in the current outbreak situation when the population is susceptible to the disease. There is a high possibility that vitamin A supplementation to cases as well as population at risk of COVID-19 has a key role in prevention and control. Hence, it is believed that along with other therapeutic and preventive measures, maintaining vitamin A sufficiency during and prior to the development of active disease may act as an adjuvant in population at risk and cases to prevent and control COVID-19.

Background: Evidence suggests that dietary pattern is related to incidence and grades of nonalcoholic fatty liver disease (NAFLD). The aim of this study was to investigate the relationship between major dietary patterns and hepatic histologic features of newly diagnosed patients with NAFLD. Methods: This cross-sectional study included 260 newly diagnosed NAFLD patients. Hepatic fibrosis and steatosis were diagnosed using Fibroscan. Dietary information was obtained using a validated 168-item semiquantitative food frequency questionnaire. The association between dietary patterns and odds ratio of the grade of fibrosis and steatosis was examined by multinomial logistic regression. Results: The mean ± SD age participant was 46.53 ± 11.71 years. Fifty-seven percent of the participants were women. Two major dietary patterns were recognized: “Western dietary pattern” and “Mediterranean dietary pattern.” After adjustment for various confounders, adherence to the two extracted dietary patterns was not associated with odds of fibrosis and steatosis (P > 0.05). However, P was not significant. Patients in the second quartile of the Mediterranean dietary pattern had a higher risk for being in the F1 grade compared to those in the reference group in the crude and adjusted model. Conclusions: The major dietary patterns of NAFLD patients living in Gilan were not related to the severity of their disease. More precise study design such as cohort or interventional studies is suggested to reveal the strength of this study findings.

Background: Oxidative stress (OS) is caused by an imbalance between prooxidant substance production and antioxidant defense. OS is involved in physiologic interactions in the body and the pathogenesis of various disorders. This study aimed to evaluate serum prooxidant-antioxidant balance (PAB) as a selective prooxidant, antioxidant defense, and acute phase reactant protein in patients with subclinical and clinical hypothyroidism. Methods: This case-control study was conducted in three groups including clinical hypothyroidism (32 patients), subclinical hypothyroidism, (42 cases), and healthy controls (32 individuals). This study was performed in the Endocrine Clinic of Arash Training and Research Hospital, Tehran, 2017. In the study groups, thyroid hormones including T4 and Thyroid Stimulating Hormone (TSH), fasting blood glucose (FBG), lipid profile, PAB, and hs-CRP as inflammatory markers were measured and compared between the groups. Results: Among 106 participants, 95.3% were females, the gender balance was similar across groups and mean age was 30.79 ± 7.65 years. FBG and lipid profile except for cholesterol level were not significantly different between the three study groups. However, cholesterol level in the clinical hypothyroid group was significantly higher than the other two groups. PAB was higher in subclinical hypothyroidism compared to healthy controls after adjustment for age and TSH levels (P value: 0.04) but there was no significant difference in the clinical hypothyroid group in comparison with healthy controls. In addition, there was no significant difference in high-sensitivity C-reactive protein (hs-CRP) between the three study groups. Conclusions: This study suggests that that subclinical hypothyroidism increases PAB in comparison to healthy control which could indicate OS response in patients with subclinical hypothyroidism, respectively.

Background: Efforts to increase the coverage of exclusive breastfeeding require extraordinary innovation supported by many parties, such as community leaders, including Housewives Peer Group activist living as a neighborhood of lactating mothers. The aim of this study was to analyze the effect of a short course on the knowledge and practice of Housewives Peer Group activists as assistance to lactating mothers in providing exclusive breastfeeding. Methods: The method of the research was pre and post-test of quasi-experimental. The population was Housewives Peer Group activists in the working area of Tlogosari Wetan Community Health Center, Semarang City. Samples were chosen using purposive random sampling to 37 Housewives Peer Group activists. The intervention given was a short course which should be attended by the group, and the post-test was assessed 1 month after conducting the pre-test. Results: The results of the Wilcoxson Match Paired test showed differences in knowledge (P < 0.05) and practice (P < 0.05) of the Housewives Peer Group activists before and after attending a short course regarding exclusive breastfeeding and lactation management. At the end of the study, the knowledge and practice of the Housewives Peer Group activists increased by 4.21 points and 3.73 points, respectively. Conclusions: Short course on exclusive breastfeeding and lactation management significantly influences the increased knowledge and practice of Housewives Peer Group activists that further improve the quality of transferred information, monitor public health, especially to increase the coverage of exclusive breastfeeding and lactation management for breastfeeding mothers.

Background: Self-care is an essential component of diabetes mellitus (DM) treatment and often depends heavily on family support. In skip generation families, children's grandparents are their primary caretakers, many of whom have chronic diseases such as DM. The objective of this study was to determine the proportion of DM patients receiving treatment at a primary care unit in Khon Kaen Province in the skip generation families and the effects of this family structure on clinical indicators of treatment outcomes. Methods: This was a prospective descriptive study in DM patients who visited a primary care unit in Khon Kaen Province from July to October 2019. Patients were asked to fill out a questionnaire interviewed, and demographic and clinical data were analyzed. Results: This study included 202 participants. We found that 11.4% of patients were in skip generation families, 91.3% of whom were elderly. We found no statistically significant association between family structure and either self-care practices or clinical indicators of treatment outcomes. Conclusions: Neither clinical indicators of treatment outcomes nor self-care practices differed between DM patients in skip generation families and those with other family structures. However, additional studies should be conducted to examine other possible factors, such as the age of the grandchildren of whom patients are the primary caretakers.

Background: There are randomized controlled trials (RCTs) about the zinc supplementation effect on circulating levels of brain-derived neurotrophic factor (BDNF). However, the findings of these studies are inconsistent. The purpose of this systematic review and meta-analysis was to determine the zinc supplementation effect on BDNF and zinc levels in published RCTs. Methods: We searched PubMed/Medline, Cochrane, Scopus, ISI Web of Science, EMBASE, “Clinicaltrials.gov”, “Cochrane Register of Controlled Trials”, “IRCT” and also key journals up to 2019. RCTs with two intervention (zinc) and control (placebo) groups that evaluated zinc supplementation efficacy on BDNF levels were included. Study heterogeneity was assessed, and then, meta-analysis was performed using the fixed-effects model. Results: Four studies were included in the present secondary analysis. Compared with placebo, zinc supplementation significantly enhanced circulating levels of BDNF [(SMD): 0.31, 95% confidence interval (CI): (0.22, 0.61)] and zinc [(SMD): 0.88, 95% CI: (0.54, 1.22)] with no considerable heterogeneity among the studies [(Q = 3.46; P = 0.32; I2% = 13.4); (Q = 2.01; P = 0, 37; I2% = 0.5), respectively]. Conclusions: Our results propose that zinc supplementation can increase the circulating levels of BDNF and zinc. This study was registered at PROSPERO as CRD42020149513.

Background: Among the common mental disorders in societies, depression is one of the most common mental disorders that affects all groups and classes of society. Students are among the groups with the highest rates of depression. Therefore, the need for a short and effective tool for screening and early detection of depression is felt. The aim of this research is to determine validity, reliability and the best cut-off point of the patient health questionnaires-9 (PHQ-9) and patient health questionnaires-2 (PHQ-2) in university students. Methods: This cross-sectional study was conducted on 246 students of Kermanshah University of medical science in Kermanshah province of Iran. They completed the PHQ-2, PHQ-9, and the Beck Depression Inventory-II (BDI-II). A structured interview was used to diagnose depression. To analyze the data, Cronbach's alpha for internal consistency, the intra-class correlation (ICC) for test–retest reliability, confirmatory factor analysis for construct validity, Pearson Correlation for Convergent validity, and receiver-operating characteristic (ROC) curve for Criterion validity was used. Results: The mean age of the participants was 20.43 ± 2.29. Cronbach's alpha coefficient for PHQ-9 and PHQ-2 was 0.82 and 0.80, respectively. The test–retest reliability based on intra-class correlation (ICC) for PHQ-9 and PHQ-2 after two weeks was 0.81 and 0.73, respectively (P < 0.001). The correlation coefficient between the PHQ-9 and PHQ-2 with the BDI-II was 0.74 and 0.64, respectively (P < 0.001). Confirmatory factor analysis showed that two-factor model and one factor model had good model fit. The best cut-off point score for the PHQ-9 was 10 with a sensitivity of 0.90 and specificity of 0.93, and the best cut-off point score for the PHQ-2 was 3 with the sensitivity of 0.71 and specificity of 0.92. Conclusions: The PHQ-9 and PHQ-2 are suitable tools to screen depression in the university students in Iran.

Background: Breast cancer is the most common cancer in women. Delay in the diagnosis of breast cancer is a major challenge that can lead to disease progression. Identifying the predictors of breast cancer screening behavior is necessary to promote early detection of breast cancer. This study aims to investigate the predictors of breast cancer screening behavior in women aged 20–69 referred to public health centers. Methods: This cross-sectional study was conducted on 17255 women aged 20–69 years old in Isfahan Province referred to Public Health Centers by the multi-stage random sampling method. data were collected based on the paper forms of women's care aged 20–69 at public health centers, Isfahan, Iran, in 2012. Using STATA 14, logistic regression was employed to explore predictors of breast cancer screening behavior at a 5% significance level. Results: The mean age of women was 36.75 ± 10.46. About 6006 (34.8%) of women had a history of breast self-examination, and among women aged over 40 years, 17.7% reported ever having a mammogram. The most important factors influencing breast self-examination were age 40–49 (OR = 1.18; 95% CI: 1.06-1.33), history of hormone consumption (OR = 1.23; 95% CI: 1.15-1.33), family history of breast cancer in first-degree relatives (OR = 14.22; 95% CI: 9.83-20.57. The most important factors influencing mammography were hormone consumption (OR = 1.26; 95% CI: 1.05-1.51), and family history of breast cancer in first-degree relatives (OR = 32.55; 95% CI: 20.08-52.70). Conclusions: Our findings indicated that the performance of breast self-examination and mammography was low. The frequency of BC screening behavior was higher among women with BC risk factors The results revealed the need for health authorities to pay attention to education in BC detection methods.

Background: According to the importance of physical activity in the child's physical and mental development and cognitive health, developing a valid, reliable, and comprehensive assessment tool for children's physical activity is mandated. The purpose of this study is the translation, cross-cultural adaptation, and validation of the Persian version of the Thailand Physical Activity Children Survey questionnaire to measure the level of physical activity in children aged between 6–9 years in Iran. Methods: This study consisted of three stages, first, the questionnaire translation into Persian language and modification of the sections according to the Iranian culture, then the evaluation of the questionnaire via a pilot study, and finally, assessing the reliability and validity of the tool. Participants of the pilot study were 250 healthy children, aged 6 to 9 years, meeting eligibility criteria, recruited through a stratified cluster sampling method from schools across Tehran. Results: The Persian version of the questionnaire demonstrated an acceptable content validity (Content Validity Index between 0.88-1). The test-retest reliability reported the Intra-Class Correlation coefficient in the acceptable range in all sections (between 0.71-1). Cronbach's alpha was reported 0.993, which indicated excellent internal consistency. Conclusions: According to the acceptable validity and reliability of the Persian version of the Thailand Physical Activity Children Survey for children aged 6–9 years, it is recommended in research and surveillance studies to determine the level of physical activity of children of that age group in Iran.

Background: The 2019 coronavirus disease (COVID-19) is a mysterious and highly infectious disease that was declared a pandemic by the World Health Organization. The virus poses a great threat to global health and the economy. Currently, in the absence of effective treatment or vaccine, leveraging advanced digital technologies is of great importance. In this respect, the Internet of Things (IoT) is useful for smart monitoring and tracing of COVID-19. Therefore, in this study, we have reviewed the literature available on the IoT-enabled solutions to tackle the current COVID-19 outbreak. Methods: This systematic literature review was conducted using an electronic search of articles in the PubMed, Google Scholar, ProQuest, Scopus, Science Direct, and Web of Science databases to formulate a complete view of the IoT-enabled solutions to monitoring and tracing of COVID-19 according to the FITT (Fit between Individual, Task, and Technology) model. Results: In the literature review, 28 articles were identified as eligible for analysis. This review provides an overview of technological adoption of IoT in COVID-19 to identify significant users, either primary or secondary, required technologies including technical platform, exchange, processing, storage and added-value technologies, and system tasks or applications at “on-body,” “in-clinic/hospital,” and even “in-community” levels. Conclusions: The use of IoT along with advanced intelligence and computing technologies for ubiquitous monitoring and tracking of patients in quarantine has made it a critical aspect in fighting the spread of the current COVID-19 and even future pandemics.

Background: The world experienced the greatest pandemic of the 21^st century with the emergence of a new and readily transmissible the coronavirus disease. Understanding knowledge, attitudes, and practices (KAP) of the public towards the pandemic is an essential part of developing effective preventive strategies. Aim: The objective of this study was to investigate the knowledge, attitudes, and practices (KAP) concerning the coronavirus (COVID-19) among population in Istanbul. Methods: This is a cross-sectional and multi-stage, stratified random sampling based on multi-center population of Istanbul. A total of 5,414 persons were contacted and 4361 participants (80.5%) gave consent. The data were analyzed using descriptive and multiple regression analyses. Results: There were significant differences between low education and high educational level with respect to age groups, gender, occupation, income, residence, number of rooms and family members (P < 0.001). Responses concerning knowledge of COVID-19 indicated that subjects with high education level were significantly higher regarding knowledge of the signs and symptoms of COVID-19 and methods of detecting COVID-19 respectively. Majority of the participants consider COVID-19 risk is higher than AIDS or Cancer (75.8% of low education vs. 67.2% of high education level (P < 0.001). Multivariate stepwise regression analysis revealed that monthly income status (P < 0.001), appropriate method of detecting COVID-19 (P < 0.001), occupational status (P < 0.001), medical mask prevent against COVID-19 (P < 0.001), eating or contacting wild animals (P < 0.001), isolation and treatment of people reduce risk (P < 0.001), isolation 14 days (P < 0.001), avoid going to crowded places such as train-metro, bus, restaurants and shopping (P = 0.003), COVID-19 spreads via-respiratory droplets (P = 0.004), afraid of travel (P = 0.026) were significantly associated with COVID-19 knowledge. Conclusions: The current study results revealed that the educational level and occupation especially sedentary are correlated positively with knowledge, attitude and practices. This finding is not surprising since higher education levels and professional status are associated with good KAP in most epidemic diseases including COVID-19. Nevertheless, the recent experience with COVID-19 has provided lessons on strategy and policy making.

Background: Various recent studies have reported that exclusive right nostril breathing (RNB) and left nostril breathing (LNB) has an immediate and sustained effect under various medical conditions. In the present study, we evaluated the effect of short-term left nostril breathing on various sleep parameters in medical students. Methods: We hypothesized that the increase in vagal tone because of LNB can help in improving the quality of sleep. The baseline sleep quality was documented before the start of study in the case and the control group using the 'Pittsburgh Sleep Quality Index' (PSQI) questionnaire. A PSQI global score of more than 5 indicates poor sleep quality. The case group practiced LNB in a graduated manner for a period of 4 weeks. Thereafter, sleep quality was documented for both the groups using the PSQI questionnaire. Results: Practicing LNB significantly lowered all the seven component scores (p < 0.05) and the global PSQI score in the case group (p-value < 0.0001), suggesting that this practice effectively improved the sleep quality in the individuals of this group. Conclusions: Overall, this study suggested that exclusive LNB practice could serve as an important lifestyle modification that can be incorporated in the routine of medical students for improving their sleep quality.

The 2019 Coronavirus Virus Disease (COVID-19) represents a global public health challenge in the twenty-first century. As of June 2020, the virus had spread across 216 countries across the globe. This paper aims to analyze and identify those existing comorbidities among COVID-19 patients that represent potential risk factors for COVID-19 complications, severe illness, and death. Multiple database resources were searched. The resources include the University of Saskatchewan library USearch, Google Scholar, PubMed, Medline, and the Google search engine. Thirty-seven articles, which included 15 different types of chronic diseases, were selected. Among the reviewed diseases and conditions, cancer, diabetes, lymphopenia, hypertension, kidney disease, smoking, chronic obstructive pulmonary disease (COPD), and organ transplant were found to represent potential risk factors for COVID-19 complications, severe illness, and death. Other conditions that require further research as to whether they predispose subjects to severe illness and death include coronary artery disease, cerebrovascular disease, valvular heart disease, gastrointestinal diseases, HIV/AIDS, asthma, and liver disease. In conclusion, this article explains the association between diseases mentioned above and the severity of COVID-19 and clearly shows the population at risk. This paper will help government bodies and decision-makers prioritize resources for these populations to reduce mortality rates and overall quality of life.

Background: Data for COVID-19 incidence and the source of infection among health care workers (HCWs) in Indian population are limited. The main objective of the study was to assess the incidence of COVID-19 infection and identify the source of infection among the HCWs in a tertiary teaching hospital. Methods: A prospective cohort study was conducted among the 2134 HCWs recruited by purposive sampling from a tertiary teaching hospital from May to August 2020 (4-month period—123 days). Over the 4-month period, all the HCWs who had symptoms or those were close contacts of COVID positive patients were traced and tested using validated COVID diagnostic test (reverse transcription–polymerase chain reaction [RT–PCR] test). A semi-structured questionnaire was used to interview each positive HCW to identify the source of exposure of the infection. Results: Incidence proportion was 9.3% among HCWs and was two times higher among males compared to females. Hazard ratio was found to be higher among males and HCWs working in the non-COVID areas. Test positivity rate was found to highest (around 57.8%) among those aged less than 30 years. The most common source of infection was infected HCW colleagues (40.9%) followed by exposure to patients in non-COVID areas (27.3%). Only 5.1% of total infection was found in HCWs who had worked in COVID zones. Conclusions: People working in non-COVID areas, those using shared workplace, dining halls, and staff hostels, must follow strict COVID protocols by using appropriate Personal Protective Equipment (PPE) and following social distancing measures.

Background: Fecal calprotectin (FC) is suggested as a novel biomarker for the diagnosis of gastrointestinal (GI) diseases; however, few studies have investigated its diagnostic value for Helicobacter pylori (H. pylori). Therefore, the current study evaluated the level of FC and its diagnostic value in patients with H. Pylori and its related conditions including gastritis and duodenitis. Methods: In this case-control study, 120 children with upper GI symptoms, who were indicated to undergo upper GI endoscopic examination, were consecutively included. Patients were categorized into different groups based on their endoscopic findings including H. pylori, gastritis, duodenitis or normal. Results: Patients with gastritis (P = 0.014) and those with duodenitis (P < 001) had significantly higher FC. The level of FC was higher in patients with H. pylori but this difference was marginally significant (P = 0.054). The level of FC had poor ability to diagnose the presence of H. pylori (P = 0.054) and gastritis (area under the curve, AUC = 0.639, P = 0.014). However, it had acceptable power to diagnose patients with or duodenitis (AUC = 0.718, P < 0.001). The sensitivity and specificity of FC for diagnosis of gastritis were 64 and 65 percent (cut-off = 45.2 μg/g), and for duodenitis were 77 and 61 percent (cut-off = 46.2 μg/g), respectively. Conclusions: FC can be considered as an objective and diagnostic tool for duodenitis. However, due to the low sensitivity and specificity, it is suggested to consider it as an objective supplementary test beside other established diagnostic modalities.

Background: Dietary quality indices are practical as an instrument to investigate the extent of adhering to a special diet to prevent cardiovascular disease (CVD) in type 2 diabetes mellitus (T2DM). Considering the lack of any systematic review with regards to this issue, our aim was to examine observational studies to test the relationship between dietary quality indices and CVD risk factors in T2DM. Methods: Systematic search was performed in Web of knowledge, PubMed, Cochrane, Science direct, Google Scholar and Scopus databases from January 1990 to July 2020. The studies exploring the relationship between dietary quality indices (diet quality score (DQS), dietary diversity score (DDS), healthy diet indicator (HDI), healthy eating index (HEI), diet quality index (DQI), Mediterranean diet score (MDS)) and lipid profile, anthropometric indices, glucose profile as well as blood pressure were eligible to be included in this review. Overall, mean changes, odd ratio (RR), correlation coefficients, and beta coefficient of outcomes were extracted, with the quality assessment of studies performed applying The Newcastle-Ottawa scale. Results: From among 1627 papers, 10 articles were included: Eight cross-sectional and two prospective (cohort) studies. The association between HEI as well as MDS and CVD risk factors was more evident in the included studies. Fasting blood sugar, hemoglobin A1c, body mass index, and waist circumference revealed the greatest inverse significant relationship with dietary quality indices in adults with T2DM. Conclusion: Overall, the findings of this study suggest that the level of CVD risk factors in T2DM decreases significantly with increase in the score of dietary quality indices. Further studies in future are required to confirm these findings.

Background: Tobacco use is an established preventable risk factor for many noncommunicable diseases and is considered as an important indicator for monitoring progress towards Universal Health Coverage (UHC) and Sustainable Development Goals (SDGs). This study aimed to determine the situation of tobacco use among Iranian adults using 2016 household survey. Methods: This is a secondary analysis of the data from 2016 nationally representative STEPwise approach to Surveillance (STEPs) survey with a sample size of 31,050. The data on tobacco consumption was gathered using questions incorporated in the survey questionnaire. Results: The prevalence of current tobacco use in Iran was 25.2 % (24.4-25.9) in men versus 4% (3.7-4.3) in women. The prevalence was higher in rural areas and among second wealth group. The prevalence of current daily cigarette smoking was 20.1% (19.4-20.7) in men versus 0.9% (0.8-1.1) in women). Average number of cigarettes per day among current cigarette smokers was 14.5% (14.1-14.9), mean age at start smoking among daily cigarette smokers was 21.6% (21.1-22), and 95.2% (94.4-96) of daily current daily cigarette smokers attempted for cessation during past 12 months. Prevalences of exposure to secondhand cigarette smoke among nonsmokers at homes and workplaces were 23.21% (22.65-23.76) and 18.04% (17.2-18.87), respectively. Conclusions: There was a large difference between the prevalence of tobacco use between men and women (25.2% vs. 4%). Higher prevalences of tobacco use in rural areas and among lower wealth quintiles require more equity-based approaches in tobacco combatting actions.

Background: Patient safety as a goal can be achieved by reporting medical errors (ME); however, most errors are never reported. The aim of this study is to explore the causes of ME, and the obstacles in reporting them amongst nurses. Methods: We conducted semi-structural interviews, with 12 nursing managers in the biggest teaching hospital in southern Iran (2015-2016). The interview guide concentrated on the causes of ME and barriers in reporting them. All face-to-face interviews were recorded and transcribed verbatim and analysed using thematic analysis. Results: In this study 4 main themes were extracted for the causes of ME: personal/social characteristics, nonprofessional practice, hospital related factors/organization contextual factors, and poor management. Also, 5 main themes (such as; personal characteristics, fear from reporting, nonprofessional practices, cultural and social factors, and error surveillance system features) were obtained with regards to barriers in reporting. Conclusions: ME can be reduced by improving professional practice and better human resource management. Also, reporting errors can be increased by focusing on cultural and social factors.

Background: Patients with multiple sclerosis (MS) are considered at higher risk of COVID-19 infection due to treatment with immune modulators and immune-suppressive agents. The exact risk factors are not clear. So, we aimed to conduct a study to determine the predictors of catching COVID-19 infection during the pandemic stage in patients with multiple sclerosis (MS). Methods: We conducted a multicenter screening study and developed an online questionnaire to collect patients' self-reported demographic features along with MS-related and COVID-19–related information. The online questionnaire link was released by the Iran Multiple Sclerosis Society (IMSS) social media channel, accessible for 4160 MS patients totally and also was sent by WhatsApp for nonmember cases. Results: Totally, 1448 MS patients participated in our study. Twenty-five (1.7%) patients were diagnosed with COVID-19, from which 4 were hospitalized, 4 were treated with medical therapy, and 17 patients had home-quarantine. The patients with COVID-19 diagnosis were more frequently treated with rituximab (28% vs 24%, P = 0.001) than others, and cardiovascular comorbidity was more frequent in this group (8% vs 1.6%, P = 0.01). Regression analysis showed that cardiovascular disease was a significant positive predictor of COVID-19 infection (OR = 5.2, 95% CI: 1.1–23.7). Conclusions: Patients with MS who have cardiovascular disease should be more monitored for COVID-19 infection as they are at higher risk of infection.

Background: Prevention of the incidences of mental disorders, psychological problems, or their rapid diagnosis is an important issue that has led to the creation of a mental health literacy concept and the development of standard tools for evaluating them. This study is the first step in the designing and psychometrics of the Mental Health Literacy Questionnaire (MHLQ) in Iran. The purpose of this study was to design the psychometric properties of the MHLQ in soldiers. Methods: This study is a methodological study that was designed in three phases: 1) Designing the instrument, 2) Assessing the items, and 3) Psychometric assessment. This study was conducted during 2017-2018, and the soldiers were selected by using a convenience sampling method from different garrisons of Tehran, Iran. To evaluate the content validity of the questionnaire 10 experts, to evaluate the face validity 9 soldiers, and for the pilot study 103 soldiers formed the sample size. Finally, construct validity was assessed among 251 soldiers. Results: In the first phase, 78 items were collected and designed. Then, based on the experts' opinions and preliminary studies, the items were reduced to 52 in the “Assessing the items phase” and then to 42 items in the psychometric phase. In the third phase, 31 items remained in the final version. The CVR and CVI scores of the 52 items were 0.91 and 0.94, respectively. Exploratory factor analysis revealed a 4-factor structure with 31 items of special value that were higher than five that accounted for 55.04 of the total scale variance. The fit indices values indicated that the model is fit for the data. In the total scale, the test–retest reliability and Cronbach's alpha were 0.81 and 0.76, respectively. Conclusion: The MHLQ of soldiers has appropriate psychometric properties and can be considered as a suitable tool for evaluation and screening as well as a basis for educational and research interventions.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the pathogen responsible for an acute respiratory disease designated COIVD-19, which has spread throughout the world. Despite all the struggles with this virus, still, the majority of societies are affected by COVID-19, which raises many questions such as are these ways of management enough, which is crucial in order to contain the virus spread, and which is not effective. In this systemic review, we tried to summarize the data on different ways of managing COVID-19 outbreaks. Through understanding the efficacy and downsides of different approaches to manage COVID-19, public health officials, governing bodies, and health care administrators may be better equipped with the tools necessary to best manage COVID-19 and pandemics. Methods: This systematic review was carried out by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Articles were selected using several databases PubMed, ScienceDirect, and Google Scholar, all peer-reviewed and published articles from December 1, 2019 to April 23, 2020 that met the inclusion criteria were selected. Results: The majority of the included articles were mathematical modeling, cohort studies (n = 9), cross-sectional (n = 6), and one case series. Most articles originated from China and then Singapore. The measures that have been practiced in these articles consisted of close contact tracing and case isolation, quarantine, strict surveillance, lockdown, and travel surveillance. Conclusions: The most effective approach is at least the combination of case detection and isolation, and contact tracing or containment measures. In the literature, travel controls seem to be ineffective, personal hygiene should be tough and emphasized.

Background: Essential hypertension is one of the fastest rising noncommunicable diseases among adolescents and poses a major public health issue globally. This study aimed to estimate the prevalence of prehypertension and hypertension among school-going adolescents in Chennai and also to delineate the role of nutritional and environmental determinants in the development of hypertension. Methods: This cross-sectional study was conducted among school-going adolescents aged 14 to 18 years in northern Chennai. Four schools (two private, two public) out of 21 were selected randomly using probability proportionate to sampling size and 401 students were recruited after consent. Data were collected using an adapted modified World Health Organization (WHO) Global School-based student Health Survey (GSHS) questionnaire; anthropometry and blood pressure measurements were done by trained healthcare professionals using standard procedures. Prehypertension was defined when systolic or diastolic pressure >90^th percentile and <95^th percentile; hypertension when systolic or diastolic pressure >95^th percentile. Data were analyzed using SPSS, descriptive statistics like frequencies, mean, and percentages were used and inferential statistics like Chi-square test and logistic regression were used to elicit predictors of essential hypertension. Results: Out of 401 participants, 185 (46.1%) were males and 216 (53.9%) were females. Overall prevalence of prehypertension and hypertension was 14.2% and 5.5%, respectively. Gender (P = 0.039), overweight/obese (P = 0.000), junk food intake for >3 days/week (P = 0.000), physical inactivity for <3 days/week (P = 0.000), and parent's history (P = 0.005) were significant determinants in the development of prehypertension and hypertension. Conclusions: Nutritional and environmental determinants play a critical role in influencing blood pressure status among adolescents, this requires lifestyle and behavioral modification.

Background: The value framework governing the health system can guide the policymaking. This study presents a set of values governing the health policies for adopting policies that are in harmony with the ideology of Iran. Methods: This study was conducted in two phases. In the first phase, using the qualitative approach, Shams et al. framework was adopted to identify values. Identification of health-related national documents (nine documents) was performed purposefully. In the next phase, semi-structured interviews on individual experts in the health system were carried out. The key question was “What values and principles govern the health policy system?” Participants included 15 individuals. Both phases were analyzed based on qualitative content analysis. Results: In this study, a taxonomy of values governing policymaking is presented. Results show that equity in different dimensions, comprehensive health and a healthy human being, pioneering in health in the region, and accountability are the most important terminal vaqlues. Individual responsibility, government responsibility for health, endogenous and extrinsic economics, fair access, transparency, efficiency, quality and integrity in the supply, development and fair allocation of public health resources, and professional commitment are the most important instrumental values in Iran. Participants believed that, despite the many higher-order documents available, the health system policymaking was not based on a predetermined value. Conclusions: It is not enough to provide a set of values in upstream documents for implementation. It is necessary to specify the relative weight of the reference values in policymaking and their relation to each other in order to apply them in policymaking.

Two highly overriding problems that the society is facing today are stress and obesity. This narrative review article explains the vicious cycle of how stress leads to obesity and vice versa. Stress and obesity are interconnected to each other through different lines of cognition, behavior, and physiology. Stress can interfere with cognitive processes like self-regulation. Stress can also influence behavior by indulging in overeating of foods that are high in calories, fat, and sugar. Stress also invigorates the generation of biochemical hormones and peptides, for example, leptin, ghrelin, and neuropeptide Y. This article also extracts the contribution of weight stigma and social stress in producing obesity in an obesogenic process. Recent Studies describe that psychological distress and elevated cortisol secretion promote abdominal fat, a feature of the metabolic syndrome, improvements in mindfulness, chronic stress, and cortisol awakening response (CAR) were associated with reductions in abdominal fat. Mindfulness intervention for stress suggests that mindfulness training improves eating patterns and the CAR, which may reduce abdominal fat over time. Obesity has a multifaceted etiology. In this review, several factors of stress are identified that affect the development of obesity. This review also provides valuable insight into the relationship between obesity and stress.

Background: Patients with multiple sclerosis (MS) suffer from a wide range of psychological and physical problems. Employment status is a crucial issue for patients with MS as unemployment while it is not completely evaluated in patients with MS. Objectives: To assess psychometrical properties of the Persian version of the Multiple Sclerosis Work Difficulties Questionnaire (MSWDQ). Methods: One hundred and sixty patients were enrolled. They were asked to fill valid and reliable Persian version of the Fatigue Severity Scale (FSS), social support scale, and Short Form Health Survey (SF-36) and translated version of the MSWDQ questionnaire. Twenty cases filed the questionnaire two weeks later to assess reliability. The intra-class correlation coefficient (ICC), Cronbach's alpha, correlation coefficients were used. Results: Mean age and mean duration of the disease were 36.8 ± 9.1, and 7.5 ± 5.1, respectively. The Cronbach alpha for psychological/cognitive barriers subscale was 0.87, for Physical barriers was 0.83 and for external barriers was 0.86. The Cronbach α for the whole questionnaire was 0.89. There was a significant positive correlation between FSS and MSWDQ score, and a significant correlation with SF-36 and social support. The ICCs of all questions were acceptable. Conclusions: Persian version of MSWDQ questionnaire is a valid and reliable instrument for evaluating work-related problems in patients with MS.

Purpose: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder. The purpose of this study was to determine the relationship between the dietary inflammatory index (DII) and the serum oxidative stress markers in patients with NAFLD. Methods: In this case-control study, 121 patients with NAFLD and 119 healthy subjects were frequency-matched on gender. DII scores were calculated by using a 168-item food frequency questionnaire (FFQ). Blood samples were collected to measure serum oxidative markers. Linear regression and odds ratio (OR) were also used in this study. Results: The mean ± standard deviation of age for case and control group was 38.04 ± 6.7 and 35.6 ± 10.2, respectively. The gender ratio (female to male) for the case and control group was 1:1.42 and 1:1.38, respectively. The mean of the DII in the patient group was significantly higher than the healthy group, (P-values < 0.01). There was a significant negative relationship between TAC and DII (B = -2.63 (95%CI: -4.59, -0.68) and there was also a positive relationship between Malondialdehyde (MDA) and DII (B = 0.15 (95%CI: 0.02, 0.28) in the healthy group, but they were not significant in the case group. After multivariate adjustment, subjects in the most pro-inflammatory DII group had 73 times higher odds of NAFLD compared to subjects in tertile 1 (OR = 72.9; 95%CI (14.3-371.9)). Conclusions: Our findings suggest a direct association between the pro inflammatory properties of diet in patient and healthy group, but no relationship between TAC, MDA, and DII in the case group.

Background: Considering the importance of non-communicable diseases (NCDs) in Iran, the aim of this study is to identify the trend in the salt (NaCl) levels of various types of traditional bread (sangak, barbari, taftoon, and lavash breads) in Tehran in 2016 and 2018 and its implication for public health. Methods: A total of 777 samples of various traditional breads were randomly collected from various districts located in Tehran in 2018. The salt content (expressed as g/100 g dry weight) in these breads were determined according to Volhard method. Results from this study were compared with those reported in 2016. Results: The present study indicated that the mean salt content in traditional breads in 2018 was significantly higher than that reported in 2016. Salt content in traditional breads collected in 2018 ranged from 0.03 to 6.52/100 g dry weight, with mean value of 1.43 g/100 g dry weight. When comparing with the permitted limit set by Institute of Standards and Industrial Research of Iran (ISIRI), there was an increase in the percentage of samples complying with the permitted limit; 50.8% (2016) vs 54.1% (2018). Conclusions: The daily salt intake increased from 1.56 g per person in 2016 to 2.31 g per person in 2018. Considering the high bread per capita consumption in Iran, it seems that half of the daily recommended salt intake could be reached exclusively through breads. Hence, the main strategies for salt intake reduction from bread could be achieved through evaluation of salt reduction programs and development of technological factors in bread baking.

Background: To estimate the pooled odds of oral contraceptive pills consumption (OCPs) use as well as pregnancy history and multiple sclerosis (MS) risk. Methods: We systematically searched PubMed, Embase, Scopus, Web of Science, Google scholar, and gray literature including references of the references as well as conference papers. The search strategy in PubMed was ((Oral contraceptive pills) OR OCP) AND (Multiple Sclerosis OR Sclerosis, Multiple) OR Sclerosis, Disseminated) OR Disseminated Sclerosis) OR MS (Multiple Sclerosis)) OR Multiple Sclerosis, Acute Fulminating) AND (gravidity) OR (pregnancy). Results: Four studies were included. The pooled odds of developing MS in women with pregnancy history compared with nulligravid women was 0.64 (95%CI = 0.53 − 0.78) (I² = 0, P = 0.5), which means that pregnancy reduces the risk of MS by 36%. The pooled odds of OCP consumption and risk of MS were 1.09 (95% CI = 0.67 − 1.76). By comparing the pooled odds of OCP consumption and risk of MS according to the country of the origin, we found that the pooled odds in Iranian studies was 1.03 (95% CI = 0.31 − 3.45) and the pooled OR in studies that were conducted in the United States was 1.13 (95% CI = 0.65 − 1.98), which showed that the country of the origin was not the cause of heterogeneity. Conclusions: The results of this systematic review show that pregnancy history is a protective factor for MS development, whereas OCP use has no significant effect.

Background: Psychological conditions aggravate during outbreaks. Here, we have discussed the existing COVID-19 depression, anxiety, and stress and the resulting stigma and its different aspects in Iranian health care workers and their 1^st-degree relatives. Methods: In this cross-sectional study, information of our study groups (237 participants including health care workers and their nuclear family members) was collected via two online stigma and depression, anxiety, and stress scale (DASS) questionnaires. Results: The DASS questionnaire's mean depression, anxiety, and stress scores were 13.59 ± 5.76, 11.07 ± 4.38, and 15.05 ± 5.86, respectively, in our study population. Marriage status was effective on depression and stress scores. Married participants were having less depression (P = 0.008) but more stressful (P = 0.029) than single ones. Education was found to be effective on anxiety and stress scores. Those with an associate, master, Ph.D., and higher college degrees were significantly less anxious and stressed than those with a diploma or bachelor's degrees (P = 0.032 and 0.016, respectively, for anxiety and stress). Participants with a history of psychiatric conditions showed significantly higher depression, anxiety, and stress rates than those without a past psychiatric condition (P = 0.001). Healthcare workers and their nuclear family members suffer from severe stigma (mean stigma scores were 33.57 and 33.17, respectively). Conclusions: Healthcare workers and their nuclear family members in Iran suffer from severe COVID-19 related stigma. We also showed that depression, anxiety, and stress are common among Iranian Healthcare workers and their nuclear family members during this pandemic. This study showed that people with preexisting psychiatric conditions need extra mental care during the pandemic.

Background: Nonalcoholic fatty liver is the most common chronic liver disease. Regarding the side effects of synthetic medicines and the variety of natural products in Iran climate, the present study aimed to investigate the effect of medicinal plants and natural products on liver enzymes in patients with non-alcoholic fatty liver disease in Iran using meta-analysis. Methods: To extract the intended studies, internal and external databases, including SID, Magiran, IranDoc, PubMed, Scopus, Web of Science, Embase, Cochrane, and Clinical Trial Registration System of Clinical trial.gov, the ISRCTN system, as well as Clinical Trial Registration System affiliated to the World Health Organization were searched. The obtained data were analyzed in STATA.14 software. A P value less than 0.05 was considered statistically significant. Results: A total of 44 rstudies were reviewed with a sample size of 1298 participant; they were published in the period from 2009 to 2018, silymarin had the highest effect on the reduction of AST (SMD = -2.68), cinnamon excreted the most profound effect on ALT (SMD = -2.69). In addition, cinnamon had the highest effect on gamma-glutamyl transferase (GGT) (SMD:-3.17), and curcumin had the highest effect on alkaline phosphatase (ALP) (SMD = -1.88). In the lipid profile, the effect of medicinal herbs and natural products on lowering total cholesterol and LDL was statistically significant. In the glycemic profile, the effect of medicinal plants and natural products on the reduction of fasting blood sugar, insulin, and hemoglobin A1c levels was statistically significant. Conclusions: As evidenced by the obtained results, the highest effect of using natural products was observed in the reduction of GGT, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels, respectively; nonetheless, the effect of natural products on ALP reduction was not statistically significant.

In December 2019, an unusual form of pneumonia of unknown origin was identified in Wuhan and soon expanded into an intercontinental pandemic that affected nations all over the world. The unusual pneumonia was subsequently named COVID-19. The management of COVID-19 disease has been highly dependent on the early identification of patients who are positive for SARS-CoV-2 infection. For detecting the SARS-CoV-2 virus in upper or lower respiratory tracts, the Centers for Disease Control and Prevention (CDC) recommend strategic sampling approaches. Most countries collect nasopharyngeal swabs and oropharyngeal swabs for rapid viral testing by experienced healthcare workers. Due to the increase in single-day cases, the high cost of RT-PCR, and the requirement for greater coverage in order to detect COVID-19 infections, the screening method has been changed to the Rapid Antigen Test during this phase of the pandemic in India. Considering the limited sensitivity of the fast antigen test compared to the sputum test, and the benefit of having additional resources available from an already established TB network, policymakers should consider implementing COVID-19 with sputum testing. For India, which has 1.3 billion people and limited resources, contemplating a community level sample collection of COVID-19 samples will be an effective decision if scientific data is used for this purpose will be an effective choice for the country with more than 1.3 billion population and limited resources.

Background: Diabetes as a chronic disease requires a change in the paradigm of treatment and health care system based on acute illnesses to chronic conditions. Chronic Care Model has been designed to address this need. This study aimed to explore the lived experiences of the diabetes team and diabetic patients regarding the health care system after redesigning delivery system and supporting self-management based on the Chronic Care Model in Iran. Methods: Research was conducted with a qualitative descriptive approach in one of the Isfahan city clinics in 2018. The participants were diabetes team (composed of diabetes physician, nurse, assistant nurse and dean of the clinic) and 17 type- 2 diabetic patients who were selected through purposive sampling. Data collection was performed through semi-structured interviews and then were analyzed using content analysis with an inductive approach. Results: The findings of this study were composed of the following two main categories: (1) educational function change, including the sub-categories of evidence-based nurse education and patients' demand to ongoing participation in the training classes; and (2) treatment and care method upgrade, including the sub-categories of nurse's role change in a team approach, continuity in cares and upgrading patients' self-care behaviors. Conclusions: Delivery system redesign and diabetes self-management support based on Chronic Care Model changed organizational structure and performance of the diabetes care system. It also reformed the structure of treatment providers from a vertical and hierarchical form to a team arrangement. Nurse's educational function became evidence-based and patients' self-care behaviors upgraded.
