Depression is defined as a cluster of specific symptoms with associated impairment affecting 7.4% of the adolescents globally. As part of the systematic review, around 1000 relevant articles published between January 1978 and December 2017 were identified by systematic online search from 6 electronic databases (PubMed, PsycInfo, Science Direct, MEDLINE, Scopus, and Google Scholar) and overall, 56 relevant studies were included in the current review as per the inclusion criteria. Findings highlight the potential importance of the relationship between healthy dietary patterns or quality and positive mental health throughout life span. Various nutrition and dietary compounds have been suggested to be involved in the onset maintenance and severity of depressive symptoms and disorders. Nutritional compounds might modulate depression associated biomarkers. In this context, several healthy foods such as olive oil, fish, nuts, legumes, dairy products, fruits, and vegetables have been inversely associated with the risk of depression and might also improve symptoms. In contrast western dietary patterns including the consumption of sweetened beverages, fried foods, processed meats, baked products have been shown to be associated with an increased risk of depression in longitudinal studies. Diet and nutrition offer key modifiable targets for the prevention of mental disorders. Evidence is steadily growing for the relation between nutrition deficiencies, diet quality and mental health and for the efficacy and use of nutritional supplements to address deficiencies or as augmentation therapies. We advocate recognition of diet and nutrition as crucial factors in prevention and management of mental disorders.

Lower extremity ulcers represent the most ominous, feared, and costly complications of diabetes mellitus. The aim of this review is to highlight the role of daily life physical activities (PAs) and continuous movement monitoring (CMM) in the prevention of foot ulcers. Peripheral neuropathy and peripheral vascular disease are the main causes of foot ulceration and contribute, in turn, to the development of additional risk factors such as foot deformities and/or joint and muscular alterations. Moreover, a deficit of balance, posture abnormalities, followed by gait alterations, increases the risk of ulceration. PA can play a key role in the management of patients with diabetes and in the prevention of ulcers; however, even if it has been reported that some of these risk factors significantly improve after a few weeks of exercise therapy (ET), the real preventive role of ET has not yet been demonstrated. These uncertain results can occur due to some limitations in the management of the same relationship between PA and diabetic foot prevention. Technological advances during the last years enable timely management of overall daily PA. The use of these modern technologies and devices allows CMM assessment and description of daily PA even in the long term. The data collected from these devices can be used to properly manage patients' PA and thus contribute to the prevention of foot ulcers.

Our aims to examine the factors influencing self-care for the prevention and control of preeclampsia in high-risk women. The current study is a review where the researcher browsed the available databases such as PubMed, Cochrane, Medline, Google Scholar, Medscape, and relevant research published between 1980 and 2016 were studied. To search for articles, relevant Medical Subject Heading keywords were first determined (Self-care, preeclampsia, prevention.) A total of 350 related articles were first selected, and the findings of 70 were used to compile the present article. The results of the study were classified under two general categories, including (1). Counseling and screening strategies and (2) self-care strategies for the prevention and control of preeclampsia in high-risk women. Screening women at risk for preeclampsia include measures such as measuring their blood pressure, checking for signs of depression, testing for thrombosis, taking a history of preeclampsia, providing preconception counseling about the appropriate age, time of pregnancy, and encouraging weight loss in obese women. This review showed a positive relationship between knowledge about self-care for preeclampsia and its control. The factors influencing preeclampsia self-care include making lifestyle changes, having a healthy diet, learning stress management, performing exercise and physical activities, taking antioxidants, dietary supplements, and calcium and adherence to aspirin and heparin regimens. There is a positive relationship between preconception counseling, screening women at risk for preeclampsia, self-care for the prevention, and control of preeclampsia. (1) Tweetable abstract self-care in high-risk women is strongly associated with prevention and control of preeclampsia.

Body image is the perception of individuals of their own body and it can be affected by many variables such as culture, social pressure, and media, but it is not limited to these factors. Body image disturbances are important because they lead to severe physical or psychological health problems. Development of body image dissatisfaction in Eastern communities has been increased in the past years. Despite many studies in Asian societies, In Iran, studies are scattered and limited. Our goal is a better understanding of this matter in Iran. A review of scientific literature about Body Image and Iran was conducted inPubMed, Web of Science, Science Direct, Scopus, and ProQuest, also in Persian scientific databases such as Scientific Information Database (SID) and Thematic Guide to Iranian Publications (MAGIRAN). This search has been conducted in January 2018. Out of 389 articles, 44 of them were selected. In these articles, study period, sample characteristics, type of study, contributing variables, type of statistical analysis, and the main result of each article were extracted. Despite using different methods for detection of body dissatisfaction, results showed that this problem has a high prevalence in Iranian population. Contributing factors were also similar to the world findings. Review of studies regarding body dissatisfaction in Iran, revealed a high prevalence of this problem. It seems there is a need for interventional programs to prevent the negative consequences of body dissatisfaction, especially in teenagers and young people. Future studies with scientific or longitudinal design, which lead to better results, are recommended.

New evidence suggests that low serum Vitamin D may cause nonalcoholic fatty liver disease (NAFLD). Hypovitaminosis D is associated with the severity and incidence of NAFLD. The objective of this study was to conduct a systematic review on randomized controlled trials (RCTs) assessing the effect of Vitamin D on serum metabolic profile among NAFLD patients. Databases including PubMed, Institute for Scientific Information Web of Science, Scopus, and Google Scholar were searched up to November 2016. RCTs which studied Vitamin D effect on metabolic profiles and liver function, and conducted among adults were included. Six articles were eligible to be considered in this systematic review. According to the result, Vitamin D supplementation might improve lipid profile and inflammatory mediators when compared with placebo. No article indicated significant effect of Vitamin D on liver enzymes except one article which revealed that Vitamin D together with calcium carbonate can reduce liver enzymes. Vitamin D supplementation may not improve anthropometric measures and glycemic index variables among patients with NAFLD. Vitamin D supplement might improve NAFLD symptoms, especially inflammatory mediators. More RCTs in different parts of world with different forms and doses of Vitamin D are necessary.

Metabolic syndrome (MetS), a series of symptoms, including abdominal obesity, impaired glucose tolerance and insulin metabolism, hypertension, and dyslipidemia, is considered as the risk of developing cardiovascular disease and diabetes that can predispose a pregnant women to serious health problem, women in the developed as well as the developing countries. This study was aimed to investigate the effects of appropriate interventions on pregnant women with indicators of MetS to further improve the outcome of pregnancy. This systematic review was performed to extract articles of randomized controlled trials (RCT) on pregnant women with indicators of ( MetS) and focusing on physical activity, dietary or lifestyle interventions on maternal health or perinatal outcomes, with searching in the Web of Science, PubMed, CDSR, Scopus, and Google Scholar were investigated. Two researchers independently evaluated the quality of the studies, being presented in all the articles and ranked the studies as high/low quality; the level of evidence was based on the number of high-quality studies and the coordination of the obtained results. Then, 17 articles, which met the inclusion criteria, were selected; among these, 7 articles studied the physical activity, 3 articles reviewed diets, 6 probed the lifestyle interventions, and 1 article was on counseling. In general, evidence suggested how the physical activity and proper diet impacts on proper weight gain during pregnancy, prevents maternal complications, and improves the outcome of pregnancy. According to the results of this systematic review, proper interventions during pregnancy can have a positive effect on maternal weight gain and the general health condition of pregnant women with indicators of MetS.
