Abstract
Concept of dietary patterns is new in the filed of nutritional epidemiology. However, it has not been focused to the extent that foods or nutrients have been considered. Although, identifying the association between nutrients and foods intake with chronic diseases is valuable yet, recent evidences have shown that the clinical trials that have used nutrients are not too successful to indicate the effects of that nutrient on the disease risk. On the other hand, the studies used dietary patterns have shown the significant effects on disease risk. Therefore, using dietary patterns analysis is an efficient method to identify diet-disease relations. However, it should be kept in the mind that dietary patterns are different across gender, ethnics, cultures and regions. It is, therefore, recommended that investigators in different countries need to assess their own community dietary patterns and emphasize on these patterns when trying to reduce chronic disease risk. The current study has been conducted to review the studies that have assessed the association of dietary patterns and chronic disease risk.

Abstract
Background: Limited data are available relating intake of fruits and vegetables to inflammatory markers and risk of metabolic syndrome. The aim of this study was to evaluate the relationship between fruits and vegetables intake and C-reactive protein (CRP) and the prevalence of the metabolic syndrome.
Methods: Fruits and vegetables intake were assessed using a validated semi-quantitative food frequency questionnaire in a cross-sectional study of 486 Tehranian female teachers aged 40-60 y. Anthropometric measurements were done and blood pressure was assessed according to standard methods. Fasting blood samples were taken for biochemical measurements. The metabolic syndrome was defined according to Adult Treatment Panel III guidelines.
Results: The reported mean daily intake of fruits and vegetables were 228±79 and 186±88 g/d respectively. Both fruits and vegetables intake were inversely associated with plasma CRP concentrations. After statistically controlling for age, BMI and waist circumference, mean plasma concentrations of CRP across increasing quintile categories of fruits were 1.94, 1.79, 1.65, 1.61 and 1.56 mg/L respectively (P for trend <0.01) and of vegetables were 2.03, 1.82, 1.58, 1.52 and 1.47 mg/L respectively (P for trend<0.01). These inverse associations remained significant after additional control for other potential confounding variables and dietary factors. After controlling for potential confounders individuals in the highest quintile of fruits intake had 34% (95% CI: 20%-46%) lower and those in the highest quintile of vegetables intake had 30% (95% CI: 16%-39%) lower chance of having the metabolic syndrome compared to those in the lowest quintiles.
Conclusion: In this study higher intake of fruits and vegetables were associated with lower risk of metabolic syndrome part of this association may be mediated through CRP. These findings support current dietary recommendations to increase the intake of fruits and vegetables as a primary preventive measure against cardiovascular disease.

Abstract
Background: Recently on the metabolic syndrome is considered as an inflammatory disease. So factors affecting inflammation are important in this condition.
Methods: This randomized cross-over clinical trial was undertaken on 42 postmenopausal women with metabolic syndrome. Participants were randomly assigned to consume a control diet (Dietary Approaches to Stop Hypertension= DASH), soy protein diet, or soy nut diet, each for eight weeks. Inflammatory markers were measured by ELISA.
Results: The difference from the control diet for E-selectin (an inflammatory markers which shows the endothelial function) was -11.4% (P<0.01) on the soy nut consumption and -4.7% (p=0.19) on the soy protein diets. Soy nut consumption reduced interleukin-18 compared to the control diet (difference from the control diet: -9.2%, p<0.01). For C-reactive protein the difference from the control diet was -8.9% (P<0.01) on the soy nut diet and -1.6% (P<0.01) on the soy protein diet.
Conclusion: Short-term soy nut consumption reduced some markers of inflammation and increased plasma nitric oxide levels in postmenopausal women with the metabolic syndrome.

Abstract
Background: Little evidence exists regarding the effects of soy consumption on the metabolic syndrome in humans. We aimed to determine the effects of soy consumption on components of the metabolic syndrome, plasma lipids, lipoproteins, insulin resistance and glycemic control in postmenopausal women with the metabolic syndrome.
Methods: This randomized cross-over clinical trial was undertaken on 42 postmenopausal women with the metabolic syndrome. Participants were randomly assigned to consume a control diet (Dietary Approaches to Stop Hypertension= DASH), soy protein diet, or soy nut diet, each for eight weeks. Red meat in the DASH diet was replaced by soy protein in the soy protein period and by soy nut in the soy nut period.
Results: Total cholesterol was significantly reduced compared to the control (P<0.01) and soy protein groups (P<0.01). The results were the same regarding the fasting insulin serum (P<0.01 compared with the control and soy protein group), HOMA-IR (P<0.01 compared with the control and soy protein group), Fasting blood sugar (P<0.01 compared with the control and soy protein group), and LDL cholesterol (P<0.01 compared with the control and P<0.05 compared with the soy protein group). Both soy nut and soy protein reduced Apo B100 compared to the control group (P<0.01).
Conclusion: Short-term soy nut consumption improved glycemic control and lipid profiles in postmenopausal women with the metabolic syndrome

Abstract
Background: Although hypertriglyceridemic waist (HW) phenotype has received much attention over recent years for its association with other metabolic abnormalities, it remains unknown whether its effects are mediated through changes in plasma concentrations of inflammatory markers. We aimed to evaluate the association between hypertriglyceridemic waist (HW) phenotype and markers of systemic inflammation and endothelial dysfunction among women.
Methods: Anthropometric and biochemical measurements were assessed in a cross-sectional study of 507 Iranian women aged 40-60 years. HW phenotype was defined as serum triacylglycerol concentration ≥150 mg/dl and concurrent waist circumference ≥89.
Results: The prevalence of hypertriglyceridemic waist (HW) phenotype was 32.2% (95% CI: 28.7, 35.7) among women. Individuals with HW phenotype had higher anthropometric measures, were older and less physically active. After control for potential confounding variables, women in different categories of WC had significantly different levels of CRP (WC main effect: P=0.001), TNF-α (P=0.01), IL-6 (P=0.001), E-selectin (P=0.007), sICAM-1 (P=0.01) and sVCAM-1 (P=0.02, 2-factor ANOVA for all). When the models were further adjusted for BMI, the difference in sICAM-1 and sVCAM-1 ceased to be significant. Significant differences in CRP (TG main effect: P=0.01), TNF-α (P=0.008), SAA (P=0.03), IL-6 (P=0.01), E-selectin (P=0.02) and sICAM-1 (P=0.01, 2-factor ANOVA for all) were found between categories of TG concentration after control for confounders. Most of these differences remained significant even after additional adjustments for BMI, except for E-selectin. There was a significant interaction between WC and TG concentration with regard to CRP, IL-6, SAA, and E-selectin.
Conclusion: This study provides evidence showing a positive association between HW phenotype and markers of systemic inflammation and endothelial dysfunction.

Abstract
Background: The clustering of cardiovascular risk factors , known as the metabolic syndrome , greatly increases the risk of developing diabetes and cardiovascular disease .individuals with the metabolic syndrome are also at increased risk for premature death from cardiovascular disease or all–cause mortality . Although is a particular importance, its epidemiology in Iran has not been studied systematically. Aim of this review of published data was to describe epidemiology of metabolic syndrome in Iran.
Methods: We searched MEDLINE, sid, magiran, iranmedex, and irandoc databases through 2014, and examined the reference lists of pertinent articles, limited to studies in humans.
Results: Total 45 studies were eligible (25 English and 20 Farsi). The findings show the high prevalence of metabolic syndrome in both sexes according to three criteria. The prevalence of metabolic syndrome was more in women than men. We found that differences in screening programs and diagnostic criteria or various ethnic groups make it difficult to compare frequencies of metabolic syndrome among various populations. Nevertheless, factors that increase risk of metabolic syndrome were age, sex, body mass index, low HDL and high triglyceride.
Conclusion: High prevalence of metabolic syndrome and relevant risk factors suggest the identification of the risk factors should be attempted to prevent syndrome acquisition.

Abstract
Background: Several studies have evaluated the effects of coenzyme Q10 on glycemic control, but there are large discrepancies between studies.
Objective: This meta-analysis of randomized controlled trials aimed to summarize the effect of Co-Q10 on diabetes’ biomarkers.
Methods: This systematic review and meta-analysis was conducted on studies published from 1998 until December 2015. We searched Pub med, EMBASE, Science direct, ISI web of science and Google Scholar to find relevant studies. Totally, our search resulted in 16 articles reporting the effects of Co-Q10 on fasting blood glucose, fasting insulin and HbA1c. Mean ± standard deviations (SD) were used for calculating mean differences. 95% confidence interval was considered between intervention and control treatments.
Results: The present meta-analysis revealed that Co-Q10 decreased fasting blood glucose (-0.20mg/dl, 95%: -0.38,-0.02). However, Co-Q10 supplementation could not effectively reduce HbA1c (0.05%; 95%: -0.22, 0.12) and fasting insulin (0.12pmol/l; 95%: -0.21, 0.44).
Conclusion: Co-Q10supplementation didn’t result in reduction in HbA1c and fasting insulin. However, it had a significant lowering effect on fasting blood glucose. It should be noted that significant changes in fasting blood glucose reported in this study was due to the extended sample size and this is not clinically significant in the present study.

Abstract
Background: Whole-grain foods have been reported to affect serum levels of inflammatory cytokines. However, we are aware of no study examining the effect of whole-grain intake on inflammatory biomarkers among children
Objective: The present study aimed to determine the effect of whole grain intake on serum levels of inflammatory biomarkers in overweight or obese children.
Methods: In this randomized cross-over clinical trial, 44 overweight or obese (BMI>85th percentile for age and sex) girls aged 8-15 y participated. After a 2-wk run-in period, subjects were randomly assigned to either intervention or non-intervention groups. Subjects in the intervention group were given a list of whole grain foods and were asked to obtain 50% of their grain servings from whole grain foods each day for 6 weeks. Individuals in the non-intervention group were also given a list of whole-grain foods and were asked not to consume any of these foods during the intervention phase of the study. A 4-wk washout period was applied following which subjects were crossed over to the alternate arm for an additional 6 wk. Fasting blood samples were taken before and after each phase of study to quantify markers of systemic inflammation.
Results: Mean (±SD) age of study participants was 11.2±1.49 years. Mean weight and BMI of subjects was 51.2±10.2 kg and 23.5±2.5 kg/m2, respectively. No significant effect of whole-grain intake on weight and body mass index (BMI) was seen compared with the non-intervention group. We found a significant effect of whole grain intake on serum levels of hs-CRP (changes from baseline in intervention group: -0.55 vs. 0.20 mg/L in non-intervention group, P=0.03), soluble inter-cellular adhesion molecule-1 (-121 vs. 23 μg/L, P=0.02), serum amyloid A (-0.59 vs. 0.32 mg/L, P=0.02) and leptin (-11.5 vs. 36.8 ng/L, P=0.02) after 6 weeks. A trend toward the significant effect of whole grain intake on serum levels of sVCAM-1 (-166 vs. -32 μg/L, P=0.07) was also observed.
Conclusion: This study provides evidence supporting the beneficial effects of whole-grain foods on biomarkers of systemic inflammation in obese children.

Abstract
Background: The higher dietary acid load may affect blood pressure, blood sugar levels, and insulin levels. The purpose of this systematic review study is to examine the relation of dietary acid load with blood pressure and blood glucose.
Methods: We searched in PubMed, Google Scholar, Scopus and Medline up to July 2016, using the keywords "dietary acid load", "serum glucose", "insulin resistance" and "hypertension ". 12 studies (6 cross-sections, 5 cohorts and 1 intervention) were included in this systematic review.
Results: Out of eleven articles related to blood pressure, three studies showed a significant relationship between dietary acid load scale and hypertension. Three studies found only a significant association between dietary acid load and systolic blood pressure, while other studies did not show any significant correlation between dietary acid load and systolic or diastolic blood pressure. Moreover, in relation to blood glucose control, among eight studies, one study demonstrated a significant relationship between increasing dietary acid load and the incidence of diabetes. One study reported a significant relation of dietary acid load with fasting blood glucose and glycosylated hemoglobin concentration. In addition, two studies indicated a significant correlation between increased dietary acid load and insulin resistance, but other studies not revealed a meaningful relationship.
Conclusion: Since most studies suggest a significant association between increased dietary acid load and higher blood pressure, therefore it seems which dietary acid load can effect on blood pressure. The results of the investigation of the relationship between dietary acid load with glucose, insulin levels or diabetes have many contradictions. According to limited studies in this field, there is a need to further trial or prospective studies regarding the dietary acid load and the incidence of diabetes, insulin levels, and other blood glucose markers.

Abstract
Background: The effects of exercise on kidney tissue in withdrawal syndrome are unclear. In this study, the effect of 8 weeks of endurance training on the protein levels of cytochrome C, caspase 8 and caspase 3 in the kidney tissue of diabetic and diabetic rats with withdrawal syndrome was investigated.
Methods: 32 male Wistar rats were used in this experimental study. After the induction of diabetes, the rats were randomly divided into 4 groups of 8. Including: diabetes control (D), morphine diabetes (D.M), diabetes + endurance training (D.ET), morphine diabetes+endurance training (D.M.ET). Then, in addicted groups, the oral method was used for morphine dependence. The training groups performed 8 weeks of endurance training protocol. At the end of the study, all rats were anesthetized, dissected and their kidneys were separated and kept at -70 degrees for further investigations. Protein levels of the indicators of this study were measured by ELISA kits. Data were analyzed using one-way ANOVA and Tukey's post hoc test at a significance level of P≤0.05.
Results: The results of this study showed a significant decrease in caspase 3 protein levels in D.ET (P=0.000), D.M.ET (P=0.000) and cytochrome C levels in D.ET (P=0.000), D.M.ET (P=0.000) groups in Comparison with group D. Also, caspase 8 protein levels in D.M.ET group (P=0.015) compared to D group and D.M.ET group (P=0.038) compared to D.M group showed a significant decrease (P≥0.05).
Conclusion: Endurance training can probably have a positive and protective effect on the reduction of kidney tissue apoptosis in diabetic and diabetic withdrawal syndrome rats.
