Abstract
Background: Considering limited data on the association between dietary inflammatory index (DII) and demyelinating autoimmune diseases, here, we studied this issue in the early diagnosed patients [e.g., preceding Multiple Sclerosis (MS) diagnosing level (Clinically Isolated Syndrome (CIS), and Radiologically Isolated Syndrome (RIS), MS, and Neuromyelitis Optica Spectrum Disorder (NMOSD)] using a case-control study among the Iranian population. Methods: A total of 291 subjects were selected as the cases (Patients with demyelinating autoimmune diseases including CIS, RIS, MS, and NMOSD, who were diagnosed less than six months before recruitment) and 297 others as controls. A 117-item semi-quantitative food frequency questionnaire (FFQ) was obtained from all of the participants and DII was calculated. Results: After controlling for potential confounders, adherence to a pro-inflammatory diet was associated with a higher risk of demyelinating autoimmune diseases (OR=2.05, 95% CI: 0.51, 3.58), EDSS (OR=2.02, 95% CI: 0.51, 3.53), active plaque (OR=1.90, 95% CI: 0.08, 3.71), higher lesion load (OR=2.11, 95% CI: 0.58, 3.64), LETM (OR=2.19, 95% CI: 0.27, 4.11), higher number of plaques (OR=2.11, 95% CI: 0.58, 3.64), and brain atrophy (OR=2.12, 95% CI: 0.57, 3.67). Conclusion: Our study suggests a possible link between the inflammatory potential of the diet and demyelinating autoimmune disease; however, further prospective cohort studies are needed to draw a causal link on this issue.

Abstract
BACKGROUND Recent studies suggest that serum vitamin D may be associated with semen parameters. In the present cross-sectional study, we attempted to investigate the association between serum vitamin D levels and semen parameters among Iranian sub-fertile men. RESULTS A total of 350 infertile men recruited for this cross-sectional study using a simple random sampling method with a mean age of 34.77 years old, body mass index of 26.67 kg/m2, serum vitamin D of 20.17 ng/ml, semen volume of 3.82 mL, sperm count of 44.48 (106/mL), sperm total motility of 38.10 %, and morphologically normal sperm of 7.0 %. After controlling for potential confounders, serum vitamin D was positively associated with semen volume (β = 0.63, 95 % CI: 0.06, 1.20), sperm count (β = 14.40, 95 % CI: 4.56, 24.25), sperm total motility (β = 18.12, 95 % CI: 12.37, 23.86), and sperm normal morphology (β = 1.95, 95 % CI: 1.07, 2.83). CONCLUSIONS The present findings suggest that higher serum vitamin D levels are positively associated with higher semen volume, sperm count, sperm total motility, and normal morphology rate. These findings, however, do not specify a cause-and-effect relationship, and there is a need for further research in this area to understand whether vitamin D supplementation can improve semen parameters.

Abstract
Background Limited and inconsistent data are available regarding the relationship between the dietary inflammatory potential (DIP) and risk of gestational diabetes mellitus (GDM). Objective The present prospective study aimed to evaluate the association between DIP score during the first trimester of pregnancy and risk of developing GDM among Iranian women. Methods In this prospective cohort study, 812 pregnant women aged 20–40 years, who were in their first trimester, were recruited and followed up until week 24–28 of gestation. Dietary intakes of study subjects were examined using an interviewer-administered validated 117-item semi-quantitative food frequency questionnaire (FFQ). DIP score was calculated from 29 available food parameters based on earlier literature. The results of a fasting plasma glucose concentration and a 50-g, 1-h oral glucose tolerance test, between the 24th and 28th week of gestation, were used to diagnose GDM. The risk of developing GDM across quartiles of DIP score was estimated using Cox regression in several models. Results At study baseline, mean (SD) age and BMI of study participants were 29.4 (±4.84) y and 25.14 (±4.08) kg/m2, respectively. No significant association was found between DIP score and risk of GDM in the crude model (RR: 1.01; 95% CIs: 0.71–1.45). When we adjusted for age the association did not alter (RR: 1.04; 95% CIs: 0.72–1.48). Even after further adjustment for maternal weight gain we failed to find a significant association between DIP score and risk of GDM (RR: 0.97; 95% CIs: 0.66–1.41). Conclusion We found no significant association between DIP and risk of developing GDM. Further longitudinal studies among other populations are needed to elucidate the association between DIP score and GDM.

Abstract
Epidemiological studies have suggested that there is an association between diet and mental health. The aim of the current study was to explore the association between dietary zinc intake and risk of depression, anxiety, and sleep quality distortion among female students of the Semnan University of Medical Sciences in a cross-sectional study. From January through October 2019, 142 female students were randomly selected from the Department of Nutrition and Food Science at the Semnan University of Medical Sciences by simple random sampling. Food frequency questionnaires (FFQs) were used to assess participants' dietary intake over the past 12 months. Depression, anxiety, and sleep quality were examined by the Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), and Pittsburgh Sleep Quality Index (PSQI), respectively. In the analysis, the crude model was adjusted for total energy intake (kcal), while the model was adjusted for energy intake (kcal), age, economic status, physical activity level, serum vitamin D level, and body mass index. Dietary zinc intake is significantly associated with depression (odds ratio (OR) (95% confidence interval (CI)): 2.34 (0.38-4.30)) and anxiety (OR (95% CI): 3.43 (2.36-4.50)), sleep disorders (OR (95% CI): 3.65 (2.16-5.13)), sleep duration (OR (95% CI): 2.62 (0.39-4.86)), and daytime dysfunction (OR (95% CI): 5.31 (2.84-7.78)) in the model, as well as sleep delay (OR (95% CI): 1.80 (1.05-2.55)) and mental quality of sleep (OR (95% CI): 1.63 (1.10-2.15)) in the crude analysis. This cross-sectional study supports the inverse association between dietary zinc intake and mood disorders, including depression and anxiety, and some indices of sleep disturbance in the Iranian female students. Further cohort or intervention studies are required to draw a firm link between dietary zinc intake and mental health.

Abstract
AIMS This study aimed to investigate the association between dietary GI and GL and risk of GDM in a group of pregnant women in Iran. METHODS A number of 812 pregnant women were recruited in their first trimester in a prospective study. A validated 117-item semi-quantitative food frequency questionnaire was used to assess usual dietary intakes of participants at study baseline. Dietary GI and GL were calculated based on earlier publications. GDM was diagnosed based on the results of a fasting plasma glucose concentration and a 50-g, 1-h oral glucose tolerance test at 24-28 weeks of gestation. Cox proportional hazards model was used to compute relative risks (RRs) and 95% confidence intervals (CI) for GDM. RESULTS Mean ± SD of age and BMI of study participants was 29.4 ± 4.84 y and 25.14 ± 4.08 kg/m2, respectively at study baseline. Mean ± SD of dietary GI was 58 ± 7 and that of dietary GL was 176 ± 42. Overall, 28.4% (n = 231) of study population developed GDM at weeks 24-28 of pregnancy. After adjustment for potential confounding variables, we found that women in the highest tertile of dietary GL were 43% more likely to develop GDM than those in the lowest tertile (95% CI: 1.01, 2.00; P-trend = 0.03). However, no significant association was seen between dietary GI (RR for the highest tertile compared to the lowest: 0.85; 95% CI: 0.61, 1.20; P-trend = 0.37), and risk of GDM. CONCLUSIONS We found that women with the highest dietary GL were at a greater risk of developing GDM during pregnancy. No significant association was seen between dietary GI and risk of GDM.

Abstract
In this study, we investigated the associations of maternal dietary iron intake during the first trimester of pregnancy and pregnancy outcomes and related complications in pregnant women of Isfahan, Iran. In this prospective study, 812 healthy first-trimester singleton pregnant women were selected randomly from 20 various health centers across Isfahan city during 2015–2016. The maternal dietary iron classified into 2 groups, including heme and non-heme iron. Factors including pre-eclampsia, gestational hypertension, gestational diabetes mellitus, intrauterine growth restriction (IUGR), and nausea and vomiting in pregnancy considered as the pregnancy-related complications. Infant's birth weight, birth height, and birth head circumference were also determined as the pregnancy-outcomes. There was a significant association between total iron consumption and infant head circumference (p = 0.01). Total maternal iron (the sum of heme and non-heme iron) was negatively associated with both infant's birth height (p = 0.006) and birth weight (p = 0.02). Non-heme iron consumption is positively associated with high-risk of IUGR (p = 0.004). Heme intake was associated with an increased risk of maternal fasting blood sugar (FBS) (p = 0.04). Higher heme, non-heme, and total iron intake were associated with lower risk of pre-eclampsia (heme: crude p = 0.05; non-heme iron: adjusted p = 0.02; total iron: adjusted p = 0.05). Maternal total iron intake was directly associated with infant head circumference, whereas, negatively associated with both birth weight and birth height. High non-heme iron intake may increase the risk of IUGR, and a high intake of heme iron may increase FBS.

Abstract
Background Body of evidence is increasing about the importance of Vitamin D (VD) for normal development of the fetus and for maternal health. As limited data are available regarding the association between maternal VD level and pregnancy-related complications and neonatal anthropometric measures, the present study aimed to evaluate the neonatal anthropometric measures including weight, high, and head circumference and pregnancy-related complications such as preeclampsia, blood pressure, gestational diabetes mellitus, and nausea and vomiting in pregnancy with 25(OH)VD level. Methods The current prospective observational study was conducted among 812 Iranian pregnant women during the first trimester in Isfahan, Iran. Needed data were collected using validated questionnaires and biochemical examinations. Results Overall, this study demonstrated an inverse significant association between VD level and chance of having low-weight infant in the adjusted model (odds ratio [OR]: 0.03, 95% confidence interval [CI]: 0.004-0.26, P < 0.001) in the first VD assessment. The same results were obtained in the second VD assessment (OR: 0.08, 95% CI: 0.01-0.40, P < 0.01). However, such associations were not seen about other neonatal measures and pregnancy-related complications. Conclusions We found that low maternal VD level might be associated with risk of low-weight infant. Such findings could be considered to implement informative interventional programs to control newborn adverse outcomes. Further studies are required to confirm these findings.

Abstract
A number of studies have assessed the association between serum magnesium (Mg) and premenstrual syndrome (PMS) in different population, but the findings have been inconclusive. Herein, we systematically reviewed available observational studies to elucidate the overall relationship between Mg and PMS. PubMed, Cochrane's library, ScienceDirect, Scopus, Google Scholar, and ISI web of science databases were searched for all available literature until January 2019 for studies evaluating the association between Mg and PMS. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of observational studies. A total of 13 studies out of 196 met our inclusion criteria and were included in our systematic review and meta-analysis. There were no associations between serum magnesium and PMS (WMD - 0.04; 95% CI, - 0.14 to 0.06; P = 0.46) during follicular or serum/erythrocyte magnesium (WMD - 0.37; 95% CI, - 1.01 to 0.27; P = 0.25)/(WMD - 0.04; 95% CI, - 0.10 to 0.03; P = 0.26) and during luteal phase except for the sub-group of studies done outside of the US in which recent association became significant and means that serum Mg is lower in PMS subjects. According to what have been discussed, although our study did not show any significant association between serum/erythrocyte Mg and PMS except for serum Mg in luteal phase in the sub-group of studies done outside of the USA, heterogeneity between studies should be taken into accounts when interpreting these results. Additional well-designed clinical trials should be considered in future research to develop firm conclusions on the efficacy of magnesium on PMS.Registration number: CRD42018114473 .

Abstract
The aim of this study was to assess the effects of a nutrition education program on overweight/obese patients with non-alcoholic fatty liver disease (NAFLD). This single-blind, parallel randomized controlled trial was conducted on 82 NAFLD patients (mean age 48.89 ± 9.85 years) in Isfahan, Iran. Patients were randomly allocated to receive nutrition education program combined with usual care or usual care alone for 2 months. Metabolic markers, including lipid profile, fasting blood glucose (FBG) and dietary intakes were obtained for each patient at baseline and at the end of the study. Nutrition education intervention resulted in a significant decrease compared with usual care in serum levels of total cholesterol (TC) and triglyceride (TG) (p < 0.05). However, our intervention did not lead to a significant improvement in FBG, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), respectively (p > 0.05). Furthermore, energy and sugar intakes of patients were reduced significantly in response to our intervention (p < 0.05). Nutrition education intervention significantly reduced serum levels of TC and TG but did not affect other metabolic markers including FBG, LDL-C, and HDL-C. Also, it could reduce total energy and sugar intake. Thus, this study could be useful to use this educational program for NAFLD patients in order to influence their metabolic markers and dietary intakes.

Abstract
AIMS A number of studies have examined the association between the serum levels of omentin and diabetes, but the findings have been inconclusive. Herein, we systematically reviewed available observational studies to elucidate the overall relationship between omentin and diabetes, including type 1 diabetes mellitus (T1DM), type 2 diabetes mellitus (T2DM), and impaired glucose tolerance (IGT) among adolescent and adult population. METHODS PubMed, Cochrane's Library, Science Direct, Scopus, Google Scholar, and ISI Web of Science databases were searched for all available literature until January 2019 for studies assessing the association between omentin and diabetes. The Newcastle-Ottawa Quality Assessment Scale was used to assess the quality of each study. RESULTS A total of 28 articles met the inclusion criteria and were included in our systematic review and meta-analysis. There was a significant association between serum omentin and diabetes (WMD-1.68; 95% CI, -2.17 to -1.19; P<0.001). The result of our sub-group analysis based on participants' health status revealed that omentin was significantly lower in T2DM and IGT subjects but not in T1DM ones compared to healthy controls. CONCLUSION We found that serum omentin level is significantly lower in T2DM and IGT patients but not in T1DM ones. These data could be used by clinicians for early diagnosis and management of diabetes. Furthermore, we need more clinical trials to investigate new agents which could influence omentin levels.

Abstract
Several investigations have been reported the beneficial effects of synbiotic in participants with obesity, but these findings have been inconsistent. Therefore, we systematically reviewed available randomized clinical trials (RCTs) to elucidate the overall effects of synbiotic supplementation on anthropometric indices among participants with overweight or obesity. Five electronic databases including PubMed, Scopus, ISI Web of science, Cochrane Library and Google Scholar were searched up to October 2018. All RCTs using synbiotic supplements to treat obesity included in this systematic review and meta-analysis. Weighted mean difference (WMD) was pooled using a random-effects model. The present meta-analysis of 23 randomized trials indicated that supplementation with synbiotic can decrease body weight (WMD: -0.80 kg; 95% CI: -1.56 to -0.03, p = 0.04) and WC (WMD: -2.07 cm; 95% CI: -3.11 to -1.03, p < 0.001). In contrast, synbiotic did not have favorite effects on BMI (WMD: -0.12 kg/m2; 95% CI: -0.40 to 0.16, p = 0.39) and body fat (WMD: 0.02%; 95% CI: -1.27 to 1.87, p = 0.74) compared with the placebo group. Meta-regression analyses revealed that the dosage of probiotic did not have any effect on anthropometric measures. Based on our findings, modulation of gut microbiota composition through synbiotic supplementation might have modest effects on body weight and waist circumference. In this field, however, our knowledge is progressing.

Abstract
BACKGROUND Most pregnancy-related complications are associated with increased risks of adverse outcomes for mother and her infant. Although, relations between diet and pregnancy's complications indicate that there may be some benefits of nutritional factors to prevent such disorders, there are rare studies regarding the associations of dietary patterns and mentioned complications. So, the aim of the present study was to determine the relationship between dietary patterns and risk of pregnancy-related complications. METHODS The current prospective observational study was based on the data collected from 812 pregnant women. Dietary data was collected using a validated semi-quantitative food frequency questionnaire. RESULTS Three major dietary patterns identified according to the results from the factor loading matrix were: (i) 'western dietary pattern'; (ii) 'traditional dietary pattern'; (iii) 'healthy dietary pattern'. Overall, this study demonstrated a marginal significant inverse association between high adherence to healthy dietary pattern and chance of having pre-eclampsia. Also, a high chance of pre-eclampsia was observed among women with the most adherence to western dietary pattern. CONCLUSION We found that dietary patterns might be associated with the risk of pregnancy-related complications. Further studies are required to confirm these findings.

Abstract
Cancer is one of the leading causes of morbidity and mortality worldwide, which increases health-care costs. It has been reported that some dietary components such as aged garlic, one of the garlic preparations with no strong odor and harsh irritating taste, exhibits anticancer effects. This review summarizes the potential beneficial effects of aged garlic on cancer incidences as well as prevention and improvement of factors related to malignancy. Electronic databases, including MEDLINE, Web of Science, the Cochrane Library, and Google Scholar were searched. All study designs which were focused on cancer incidence, or indices related to malignancy as outcomes in human, animal, and human cells studies, and aged garlic and its ingredients as exposures were reviewed in accordance to the items for systematic reviews (PRISMA) guidelines. Initially, 304 articles were identified. Then, 25 articles which met the inclusion criteria were selected. Based on the evaluation, overall quality score of human studies was well. Although there were inconsistent evidence from human studies, results of the animal and laboratory results were mostly consistent. The overall findings may suggest that intakes of aged garlic are inversely associated with cancer. In this regard, the studies have shortcomings. Therefore, more precise investigations will be necessary to decide whether aged garlic consumption is recommendable as a part of cancer prevention or control programs. However, due to anticancer properties of aged garlic, its consumption along with healthy diet may have beneficial effects on cancer.

Abstract
A number of studies have examined the association between dietary patterns and semen quality, but the findings have been inconclusive. Herein, we conducted a systematic review and meta-analysis of observational studies to assess the association between dietary patterns and semen quality. PubMed, Cochrane library, Science direct, Scopus, Google Scholar, and ISI web of science databases were searched up to August 2016 for observational studies assessing the association between common dietary patterns and sperm quality markers. Data were pooled by the generic inverse variance method with random effects and expressed as mean differences with 95% confidence intervals (CIs). Heterogeneity was assessed (Cochrane Q-statistic) and quantified (I2 -statistic). The Newcastle-Ottawa Scale assessed study quality. Six eligible studies, involving 8207 participants, were included in our systematic review and meta-analysis. The pooled mean difference of sperm concentration for the healthy dietary pattern versus unhealthy dietary pattern intake was mean difference: 0.66; 95% CI, 0.305-1.016; p < 0.001. In comparison with those who had the highest adherence to healthy dietary pattern, individuals in the lowest adherence had significantly lower level of sperm concentration. However, no significant association was seen between eating patterns and other semen quality. Healthy dietary pattern seems to be associated with elevated sperm concentration level. Further longitudinal studies are needed to clarify this relationship.

Abstract
BACKGROUND Visfatin is a new adipocytokine which is largely secreted by visceral adipose tissue and its effects in the development of diabetes and inflammatory reactions are similar to insulin. It acts synergistically with insulin in increasing glucose cellular uptake, stimulating glucose transfer to the muscle and adipose tissue, as well as in preventing hepatic glucose production. Its insulin-like effects are mediated through direct connection and activation of insulin receptors without any change or competition with the insulin. METHODS This case-control study was conducted among 64 women consisting of 32 diabetic patients, and 32 age-matched healthy controls. The case group consisted of 32 post-menopausal diabetic women, aged 45-65 years. Those patients were eligible who had a history of at least five years of type II diabetes, without any complications of diabetes, and who were treated only by oral glucose-lowering medications. Those individuals with C-reactive protein (CRP) test of 3+ and above were excluded from the study. Results were compared with age- and sex- matched controls. RESULTS Average visfatin level was significantly higher in diabetic patients than in controls (4.3 ± 1.06ng/dl vs. 3.15 ± 0.74ng/dl, respectively< 0.001). The mean values of anthropometric indexes and lipid profile were not significantly different between diabetic patients and controls CONCLUSION This study documented an inverse relationship between circulating level of visfatin and fasting blood glucose. This finding may suggest the role of increased visfatin level and increase in synthesis and secretion of the cytokines from adipocytes. These findings may be useful for primary and secondary preventive issues in diabetic and pre-diabetic individuals.

Abstract
BACKGROUND Hypertension is a condition normally detected in people with type II diabetes.It eventually leads to cardiovascular diseases in the patient. Visfatin is an adipocytokine which issecreted from adipose tissue and can affect the inflammatory reaction and also serum lipidlevels. Additionally, omega-3 inhibits the accumulation of fat and formation of insulinresistance. The current study tried to investigate the effects of omega-3 on blood pressurecompared to placebo and the relationship between serum visfatin levels and blood pressure. METHODS A total number of 71 women with type II diabetes were randomly assigned to2 groups to receive either omega-3 capsules or placebo capsules. In the first step, aquestionnaire consisting age, height, weight, waist and hip circumferences, and systolic anddiastolic blood pressure was filled out for each subject. Blood samples were then collected forlaboratory tests. The next step was to conduct 8 weeks of intervention. All variables, except age,were measured again after the intervention. Hip circumference was considered as the maximumcircumference of the buttocks. Waist circumference was measured by placing a tape horizontallyacross the abdomen at the end of a normal exhalation. Laboratory tests included the assessmentof visfatin, glucose, and glycated hemoglobin (HbA1c) concentrations. Lipid profile, i.e. lowdensity lipoprotein (LDL), high density lipoprotein (HDL), triglyceride (TG), and cholesterol,was also assessed. Using SPSS18, data obtained from the study was analyzed by a variety ofappropriate statistical tests. RESULTS There was a significant change in mean differences of systolic and diastolic bloodpressure. Blood pressure showed a significant reduction in the omega-3 group compared to theplacebo group. However, no significant changes were observed in systolic and diastolic bloodpressure before and after the intervention (P > 0.05). CONCLUSION Based on the results of this study, a daily consumption of omega-3 is suggestedfor patients with type II diabetes.

Abstract
BACKGROUND Diabetes mellitus is a heterogeneous metabolic disorder characterized by hyperglycemia. Studies showed paraoxonase activity, and vitamin C and A levels are decreased in diabetes. The effect of omega-3 fatty acids on serum paraoxonase activity and vitamins A, E, C in patients with type 2 diabetes is not fully understood. This study aimed to determine the effect of omega-3 fatty acids on paraoxonase activity, vitamins C, A and E levels in type 2 diabetic patients. METHODS In a double-blind, placebo controlled trial, 80 type 2 diabetic patients were randomly enrolled into the study. Study subjects received daily 2714 mg of omega-3 fatty acids or placebo for 8 weeks. Ten milliliter fasting blood was collected before and after treatments. Serum paraoxonase activity and vitamin C levels were measured by spectrophotometry. Vitamin A and vitamin E were measured using high performance liquid chromatography. Nutrient intake was estimated using 24-hours dietary recall questionnaire (for 2 days) before and after treatments. Dietary data were analyzed using FPII. To compare the means of variables between the two groups, independent t-test was employed. Differences between variables before and after interventions were calculated using paired t-test. RESULTS Serum levels of paraoxonase activity were significantly increased after omega-3 intake (126.47 IU/ml vs. 180.13 IU/ml). However, omega-3 intake caused no significant change in serum vitamin A, C, and E. CONCLUSIONS Supplementation of omega-3 fatty acids was found to increase paraoxonase activity in diabetic patients.

Abstract
BACKGROUND Visfatin is an adipocytokine which is secreted from adipose tissue and can affect on the diabetes inflammatory reaction and also serum lipids level. On the other hand, Omega-3 can also prevent formation of insulin resistance. In the present study, the effect of Omega-3 on the serum visfatin concentration was evaluated. METHODS 71 women with type II diabetes were randomly assigned to the group that took Omega-3 capsules or control group with placebo capsules. In the first step, study subjects filled a questionnaire collecting their age, height, weight, waist circumference, and hip circumference. Also their blood samples were taken for blood tests. In the second step, the intervention was done for 8 weeks and in the third step the aforementioned were collected again. In the blood samples visfatin and lipid profiles (low density lipoprotein [LDL], high density lipoprotein [HDL], triglyceride [TG], and cholesterol), glucose and HbA1c were measured. RESULTS There was no significant difference in serum visfatin level between Omega-3 and placebo groups before the intervention (p = 0.14), while after the intervention, the mean serum visfatin level in the Omega-3 group was significantly higher (p < 0.001). In addition, the mean difference between the serum visfatin level before and after the intervention in both groups was significant (p < 0.001). CONCLUSIONS This study showed an increase in visfatin level following consuming Omega-3 fats but according to controversial issues on insulin-like function of visfatin, the effects of Omega-3 on diabetes should be studied more in further studies.
