Background/Objectives: Nowadays, metabolic syndrome (MetS) is deemed as a major public health challenge in both developed and developing countries. Therefore, the aim of this study was to determine the association between Healthy Eating Index-2010 (HEI-2010) score and MetS and its features among Iranian female nurses. Subjects/Methods: This cross-sectional study was performed among 1036 Iranian women. A validated, self-administered, dish-based, semiquantitative food frequency questionnaire was used to assess the habitual intake of participants. HEI-2010 score was used to assess diet quality of participants. MetS was defined based on the guidelines of the National Cholesterol Education Program Adult Treatment Panel III (ATP III). Multivariate logistic regression adjusted for potential confounders was used to assess the relation between HEI-2010 and MetS. Results: After adjusting for potential confounders, participants in the highest quartile of HEI-2010 had the lowest risk of MetS compared with those in the first quartile (odds ratio: 0.72; 95% confidence interval: 0.50-0.96). Furthermore, the risk of MetS features including abdominal obesity, high blood pressure, high serum triacylglycerol and low serum high-density lipoprotein-cholesterol significantly decreased across HEI-2010 quartiles (P Conclusions: Higher HEI-2010 scores were inversely associated with lower risk of MetS and its components among Iranian women., Author(s): S Saraf-Bank [sup.1] [sup.2] , F Haghighatdoost [sup.1] [sup.2] , A Esmaillzadeh [sup.1] [sup.2] [sup.3] [sup.4] , B Larijani [sup.5] , L Azadbakht [sup.1] [sup.2] [sup.4] [sup.6] Author Affiliations: [...]

The potential link between dysbiosis, features of metabolic syndrome (MetS), inflammation, and sensation impairment has been recently recognized. However, in this context, there are few indications available regarding the effects of co-supplementation with Bacillus indicus , Bacillus coagulans , and fructooligosaccharide (FOS) prebiotics on patients with MetS. Therefore, this study aimed to investigate the effects of synbiotic supplementation on glycemic indices, inflammatory biomarkers, and appetite among adults with MetS. This study is a randomized, double-blind, placebo-controlled clinical trial conducted in the Endocrine and Metabolism Research Center outpatient clinic in Isfahan, Iran. Fifty-eight MetS patients were randomly assigned to receive either synbiotics ( n  = 29) or placebo ( n  = 29) supplementation twice per day for 8 weeks. Finally, 55 patients were recruited for analyses (28 in the intervention group and 27 in the placebo group). Random permuted blocks and a computer-generated random number table were used for treatment allocation. No adverse effects were reported during the study. There were no significant differences in glycemic indices and inflammatory markers within- and between groups (all p  > .05). However, a significant increase in the sensation of fullness was documented in the synbiotic group. In conclusion, the eight-week treatment did not improve glycemic control and inflammatory markers. Nevertheless, it demonstrated potential efficacy in enhancing participants' appetite sensations, warranting further evaluation in longer intervention periods during future clinical trials., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

Osteoporosis is a systemic skeletal disease manifesting as weak and fragile bones. Dietary patterns have been described as an affecting constituent of bone metabolism. There is no consensus on the advantages or harms of vegetarian diets on bone health. This study aimed to design a lacto-vegetarian dietary score (LVDS) to evaluate the similarity of an individual's dietary pattern to the lacto-vegetarian dietary pattern and assess its association with postmenopausal osteoporosis (PMO). We hypothesized that individuals with greater LVDS will have a lower risk for PMO. In this hospital-based, case-control study, 220 cases (definitively diagnosed with osteoporosis) and 220 age-matched controls were registered. Usual dietary intakes were evaluated by a validated 147-item semiquantitative food frequency questionnaire. To design the LVDS, the energy-adjusted intakes of 12 food groups were categorized into quintiles, and positive or reverse points were assigned. To determine the association between the LVDS and PMO, binary logistic regression was used. Those in the top tertile of the LVDS had a lower chance of PMO compared with those in the bottom tertile (odds ratio, 0.11; 95% confidence interval, 0.06-0.22). An inverse relation was obtained between vegetables, fruits, legumes, nuts, dairy, soy protein, and egg consumption and PMO. Higher consumption of vegetable and animal oils significantly increased the risk of PMO. A dietary pattern similar to the lacto-vegetarian dietary pattern and concentrated on greater consumption of legumes, nuts, dairy, fruits, vegetables, and soy protein can be suggested as a protective method against PMO. Further, longitudinal studies are required to confirm these findings., Competing Interests: Author Declarations None., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Global increase in the prevalence of age-related diseases, such as sarcopenia, highlights the need of recognizing agents that improve muscle health; however, the evidence synthesis on the impact of probiotic administration on sarcopenia is scarce. To summarize and evaluate findings regarding the effect of supplementation with probiotics on sarcopenia, this meta-analysis was conducted. Using databases, including PubMed, SCOPUS, ISI-Web of Science, and Cochrane Library, interventional studies were included if they investigate the effect of probiotic administration on at least one of the components of sarcopenia up to 6 October 2022. Risk of bias evaluation was conducted using the Cochrane quality assessment tool. The random-effects model which takes between-study variations into account was used to obtain the overall effect sizes. The STATA version 14.0 was used for statistical analyses. Overall, 17 studies were included. There was high certainty of evidence that probiotic supplementation has a beneficial effect on muscle mass (kg) (WMD: 0.55, 95% CI: 0.05, 1.05; I 2 : 0.0%, p  = .995), and muscle function (WMD: 0.13, 95% CI: 0.03, 0.23; I 2 : 65.6%, p  = .05). Moreover, administration of probiotics for more than 12 weeks significantly increased muscle strength (WMD: 1.16, 95% CI: 0.88, 1.44; I 2 : 0.0%, p  = .77). However, probiotic supplementation had no effect on anthropometric indices, including body mass index. Probiotic supplementation could improve muscle mass and muscle function in adults more than 55 years old. The beneficial effect of probiotics on muscle strength could appear after 12 weeks of supplementation., Competing Interests: The authors declare that they have no conflict of interest., (© 2023 The Authors.

Purpose: The aim of this comprehensive systematic review and meta-analysis was to evaluate the beneficial effects of melatonin supplementation on brain-derived neurotrophic factor (BDNF) concentration and clinical depressive disorder., Methods: A comprehensive electronic search was conducted of Medlin, Web of Science, Science Direct, and Google scholar, from database inception to January 20, 2021. Studies were eligible if they: (1) were a clinical trial; (2) enrolled adults; (3) assessed the effect of melatonin supplementation on serum concentration of BDNF or depression score. Overall effects, as weighted mean difference (WMD), were calculated for concentration of BDNF and depression score., Results: Melatonin supplementation yielded no significant effect on BDNF concentration (WMD: -5.61; 95% CI: -14.10, 2.88; I-square: 85.6%), but improved depression by decreasing the score (WMD: -0.76; 95% CI: -1.12, -0.4; I-square: 88.0%). Due to high heterogeneity between studies, subgroup analysis for gender, duration and dose in BDNF studies and duration, age, dose, continent and Questionnaire type in depression studies, was utilised. The subgroup analysis showed that melatonin supplementation had a significant decreasing effect on BDNF levels in doses ≤ 10 mg/day, with more than 4 weeks of duration, and in men., Conclusion: The present study revealed that melatonin supplementation has a decreasing effect on depression in all duration of studies and doses subgroup and in age more than 65 years in depression studies but heterogenicity of the included studies, did not allow a definitive conclusion. There is limited evidence for effects of melatonin on serum BDNF., Implications for Practice: Melatonin is a safe and effective supplement for depressive patients., Competing Interests: Conflicts of interest None., (Copyright © 2022 Elsevier B.V.

Background and Objective: Inconsistent evidence showed that folate supplementation may be associated with reduced risk of cancer due to improved metabolic profiles and reduced markers of oxidative stress and inflammation. The aim of this investigation was to quantify the effects of folate supplementation on the recurrence and other metabolic factors of women with cervical intraepithelial neoplasia grade 2/3 (CIN2/3)., Methods: This randomized, double-blind, placebo-controlled clinical trial was performed among 60 overweight/obese women with CIN2/3. Definitive CIN2/3 confirmation was done via biopsy, pathological diagnosis, as well as colposcopy. Participants were randomly assigned to the intervention group to take 5 mg/day folate supplements or placebo group (n = 30 in each group) for 12 weeks., Results: The results of the current study showed a non-significant decrease in recurrence of CIN2/3 in the folate group in comparison with the placebo group (3.3% vs. 16.7%, P = 0.08). Compared with the placebo, folate supplementation significantly decreased plasma homocysteine (Hcy) levels (P < 0.001), serum insulin values (in the crude model) (P = 0.01), and homeostasis model assessment of insulin resistance (P = 0.01). Also, folate supplementation resulted in a significant improvement in the quantitative insulin sensitivity check index (P = 0.002) and total antioxidant capacity (P = 0.04) and a significant reduction in high-sensitivity C-reactive protein (P = 0.015) in comparison with the placebo group., Conclusions: In conclusion, folate supplementation for 12 weeks among overweight/obese women with CIN2/3 showed a non-significant decrease in its recurrence and had beneficial effects on insulin sensitivity, inflammation, and oxidative stress markers., (© 2021.

Previous studies of the effect of vtamin D on serum levels of fibroblast growth factor- 23 (FGF-23) have yeilded an inconsistent findings. This systematic review and meta-analysis of randomized controlled trials (RCTs) sought to investigate the effect of vitamin D supplementation on serum levels of FGF-23. PubMed, Scopus, ISI Web of Science, and the Cochrane Library were searched, from database inception to November 2020, for RCTs that evaluated the effects of native or active vitamin D supplementation on serum levels of FGF-23 in adults. Weighted mean difference (WMD) were calculated and random effects meta-analysis was used to estimate the overall effects. Twenty-seven trials were included in the meta-analysis. Supplementation with native vitamin D (23 studies, n = 2247 participants; weighted mean difference [WMD] = 0.5 pg/mL, 95 % CI: -0.52 to 1.51, P = 0.33; I 2 = 29.9 %), and active vitamin D (5 studies, n = 342 participants, WMD = 29.45 pg/mL, 95 % CI: -3.9 to 62.81, P = 0.08; I 2 = 99.3%) had no significant effects on serum FGF-23 concentration. In subgroup analyses, supplementation with ergocalciferol (3 studies, n = 205 participants; WMD = 18.27 pg/mL, 95 % CI: 5.36-31.17, P = 0.006), and daily dosing regimens (9 studies, n = 1374 participants; WMD = 0.41 pg/mL, 95 % CI: 0.22 to 0.59, P < 0.001) increased serum FGF-23 levels compared to control. Overall, our findings revealed no significan effect of vitamin D supplementation on serum FGF-23 concentration. However, further high quality, large-scale studies are needed to better elucidate this relationship., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

Increasing macular pigment optical density (MPOD) as a result of increased macular concentration of lutein and zeaxanthin may reduce the risk of age-related macular degeneration (AMD). The aim of the present study was to determine whether the consumption of eggs, a rich source of dietary lutein and zeaxanthin, influences MPOD and serum lutein. In this systematic review and meta-analysis we searched PubMed, Scopus, and ISI Web of Science up to July 2020, for relevant randomized clinical trials. Using a random-effects model, pooled weighted mean differences, and standard deviations (SDs) for each outcome were obtained. The quality of the eligible studies was assessed by the Cochrane Collaboration's tool. A meta-analysis of five trials (296 participants) revealed that egg consumption significantly increased MPOD (weighted mean differences (WMD): +0.037; 95% CI: 0.004, 0.069; P = 0.027) and serum lutein (WMD: +0.150 μmol L̂-1; 95% CI: 0.037, 0.263; P = 0.009). Subgroup analyses showed that egg consumption: (a) had a larger effect on MPOD in studies with a parallel design; and (b) increased serum lutein to a greater extent in a healthy population. We did not detect any heterogeneity between studies. Daily egg consumption has beneficial effects on MPOD and serum lutein is inversely associated with reduced AMD progression. Further clinical trials are required to confirm the results of this study. © 2021 Society of Chemical Industry., (© 2021 Society of Chemical Industry.)

Objectives: The generation of key nephrovascular protein-bound uremic toxins, indoxyl sulfate and phenol, in hemodialysis (HD) patients is attributed to the dysbiotic gut microbiota. The aim of this study was to investigate the effects of synbiotic supplementation on serum levels of indoxyl sulfate, phenol, inflammation, and biochemical parameters in HD patients., Methods: Forty-two HD patients (synbiotic group: n = 21; placebo group: n = 21) were analyzed in this randomized, double-blind, placebo-controlled study. During a 2-mo intervention, the synbiotic group received two synbiotic capsules daily, between the main meals, whereas the placebo group received maltodextrin as the placebo. Blood pressure, uremic factors, and biochemical parameters were assessed before the start and after the end of the study., Results: After adjustment for potential confounders, there was no significant effect of synbiotic on serum levels of urea, creatinine, liver enzymes, high-sensitivity C-reactive protein, sodium, potassium, phosphorus, blood pressure, or albumin in the treatment group compared with the placebo group. A significant increase in indoxyl sulfate and parathyroid hormone levels were observed only in the treatment group. However, between-group analyses were not significant. Compared with baseline values, phenol levels were decreased in both groups (P≤001), with no significant between-group difference., Conclusions: Synbiotic supplementation might increase indoxyl sulfate and parathyroid hormone levels in HD patients., (Copyright © 2019 Elsevier Inc.

Background: Hyperlipidemia and hypertension are the most important causes of ischemic heart disease. There is evidence that flaxseed powder can improve lipid profile and blood pressure. In this study, we want to investigate the effects of flaxseed powder consumption on patients with hyperlipidemia and hypertension., Methods: This randomized double-blind placebo-controlled clinical trial was performed on 80 hyperlipidemic and hypertensive patients (men and women between 20 and 60 years old). In this study, participants were recruited from Imam Khomeini hospital clinics of Shiraz University of Medical Sciences in 2017 randomly allocated to flaxseed powder group and placebo group. The intervention group received 36 g of flaxseed sachet ( n = 40), and control group received 12 g placebo sachet ( n = 40) for 8 weeks. Serum lipid profiles, blood pressure, fasting blood sugar, and anthropometric indices were measured. Data were analyzed by using SPSS., Results: We found significant reduction ( P < 0.001) in anthropometric indices (waist circumference and waist-to-hip ratio) and lipid profiles (triglycerides [ P = 0.015], total cholesterol [ P = 0.018], and low-density lipoprotein [ P < 0.001]) within flaxseed group in comparison with placebo group., Conclusions: Based on beneficial effects of flaxseed on cardiovascular risk factors, it seems that flaxseed consumption can be considered as a useful therapeutic approach for reducing lipid profile and anthropometric indices., Competing Interests: There are no conflicts of interest., (Copyright: © 2019 International Journal of Preventive Medicine.)

Background: Obese adolescents are at higher risk of development of cardiovascular risk factors and obesity in later life. Dietary intake of antioxidants, particularly curcumin, as an active ingredient of turmeric extract, may have noticeable effects on obesity and its important complications such as cardiovascular risk factors. Therefore, the aim of this study was to assess the effects of curcumin supplementation on cardiovascular risk factors among overweight and obese female adolescents., Design and Setting: Randomized placebo-controlled clinical trial; Pediatric Cardiovascular Research Center, Isfahan, Iran., Methods: 60 adolescent girls (aged 13-18 years) were randomly assigned to receive either placebo or intervention. The adolescents were asked to consume one 500 mg tablet per day, containing either standardized 95% turmeric extract or placebo, and to undergo a weight maintenance or a mild weight loss diet for 10 weeks. Anthropometric and biochemical indices were assessed at the baseline and the end of the intervention., Results: Curcumin supplementation had beneficial effects on body mass index (P = 0.019), waist circumference (P = 0.008), hip circumference (P = 0.030), high-density lipoprotein levels (P = 0.042) and triglyceride/high-density lipoprotein ratio (P = 0.021). However, in univariate analysis of covariance, no significant differences were found between the intervention and placebo groups after 10 weeks of supplementation (P > 0.05)., Conclusions: Prescription of curcumin supplementation along with use of a slight weight loss diet might have beneficial effects on some cardiovascular risk factors among overweight and obese female adolescents. Larger clinical trials with higher curcumin doses and longer duration are needed to confirm the results from the current study., Clinical Trial Registration: IRCT20171107037302N1.

Introduction: It is well known that there is a strong linkage between obesity, systemic low-grade inflammation, and oxidative stress in the pediatric population. Possible strategies that might control obesity and its relevant problems in this crucial group are of utmost importance. Therefore, the aim of this study was to evaluate the effects of curcumin supplements on inflammation, oxidative stress, and chemerin levels in adolescent girls., Methods: Totally, 60 overweight and obese adolescent girls were randomly assigned to either placebo or intervention group in a randomized placebo-controlled parallel trial design. Adolescents consumed one 500-mg curcumin or placebo per day along with a slight weight loss diet for 10 weeks. High-sensitive C-reactive protein (hs-CRP), interleukin 6 (IL-6), total antioxidant capacity (TAC), malondialdehyde (MDA), chemerin levels, and anthropometric measurements were assessed at the beginning and end of the trial., Results: Curcumin supplementation had a significant effect on IL-6 levels and oxidative stress markers including TAC and MDA in crude model. After controlling the effects of confounders, curcumin supplementation had a substantial effect on inflammation (hs-CRP and IL-6) and oxidative stress (TAC) marker of adolescents., Discussion: Ten weeks of curcumin supplementation had beneficial effects on inflammation and oxidative stress markers among postpubescent overweight and obese girl adolescents., (© 2019 John Wiley & Sons, Ltd.)

Background: The aim is to investigate the association between diet quality and daily price of foods consumed among Iranian diabetic patients., Methods: This cross-sectional study was conducted among 200 patients with type 2 diabetes mellitus (T2DM) aged 30-70 years. General information, socioeconomic status, anthropometric and biochemical characteristics, and food prices were collected by pretested questionnaires. Dietary intakes were assessed using a semi-quantitative reliable and valid food frequency questionnaire. Modified nutritionist IV and SPSS software were used for analyses., Results: The results of the present study indicated a direct relationship between total daily price of diet and nutrient adequacy ratio of Vitamin D, Vitamin B1, selenium, zinc, magnesium, potassium, and mean adequacy ratio of 11 micronutrients (Vitamin C, Vitamin E, Vitamin D, Vitamin B1, Vitamin B6, Vitamin B12, selenium, zinc, calcium, magnesium, and potassium) ( P < 0.05). Furthermore, the total daily price of diet had a positive association with dietary intakes of protein, Vitamin D, Vitamin B1, selenium, zinc, magnesium and potassium among type 2 diabetic patients ( P < 0.05). However, no significant relationship was observed between the total daily price of diet and anthropometric indices, biochemical characteristics, and socioeconomic status of participants in the present study ( P > 0.05)., Conclusions: This study showed that dietary quality and dietary intakes of energy, protein, and micronutrients were directly associated with the total daily price of foods among Iranian patients with type 2 diabetes., Competing Interests: There are no conflicts of interest.

Backgrounds & Aims: Recently, an increasing interest has been addressed to the acid-base imbalance in the pathogenesis of diabetes while we are not aware of any study among patients affected by gestational diabetes mellitus (GDM). Therefore, the purpose of present study was to reveal the potential relation between dietary acid load (DAL) and glycemic indices, lipid profiles and GDM odds ratio among Iranian pregnant women with GDM., Methods: This case-control study (hospital-based setting) was performed in singleton fetus pregnant women; healthy (n = 263) and GDM (n = 200), aged 22-44 years, and between weeks 5-28 of pregnancy. Three-day 24-h dietary records were applied to determine usual intakes of women. The tertiles of protein to potassium ratio (Pr/K) and potential renal acid load (PRAL) were calculated and used for statistical analyses., Results: Across tertiles of both DAL scores, fasting blood sugar, HbA1C, total cholesterol and LDL-C increased significantly. Diastolic blood pressure of participants significantly increased only across the tertiles of Pr/K ratio. Participants in the highest tertile of Pr/K and PRAL had more than 7 (OR = 7.60; 95% CI: 3.43-16.84) and 9 times (OR = 9.27; 95% CI: 4.00-21.46) increased odds of gestational diabetes mellitus, respectively., Conclusion: Women with higher scores of DAL were more likely to have gestational diabetes mellitus during pregnancy., (Copyright © 2017.

Introduction: Cardiovascular disease (CVD) is one of the most important causes of mortality. Healthy diets can decrease CVDs and other chronic diseases especially in patients with type 2 diabetes. In this study, we investigate association between adherence to the modified Nordic diet and cardiovascular risk factors among patients with type 2 diabetes. Methods: This cross-sectional study was conducted among 339 type 2 diabetic patients. Anthropometric indices, blood pressure, and biochemical tests were evaluated. A validated and reliable semi-quantitative food frequency questionnaire (FFQ) was used to assess dietary intake. Nordic diet scores were calculated based on median intakes of six food groups. Results: Body mass index (BMI) was higher among participants who were in the lowest tertile of adherence to the Nordic diet ( P =0.006). There was a significant association between socioeconomic status (SES) and adherence to the Nordic diet ( P <0.0001). Participants who were in the top category of adherence to the diet had significantly lower levels of aspartate aminotransferase (AST) ( P <0.0001). There was a significant inverse association between adherence to the Nordic diet and low density lipoprotein (LDL) levels (odds ratio [OR]=0.29 95% CI: 0.09, 0.91, P =0.025), high systolic blood pressure (SBP) levels (OR=0.35 95% CI=0.17-0.74, P =0.015), and risk of obesity (OR=0.25 95% CI: 0.10, 0.63, P =0.03). Conclusion: Results suggest that adherence to the Nordic diet is associated with reductions in the prevalence of obesity, LDL levels and blood pressure among type 2 diabetic patients. However, additional studies are needed to confirm these findings.

Background: Retinol-binding protein 4 (RBP4) is known to regulate lipid and glucose metabolism and insulin resistance. The influences of RBP4 on metabolic syndrome (MS) are still unclear. The purpose of this study is to evaluate the association between serum levels of RBP4 and MS components in first-degree relations of type 2 diabetic patients., Materials and Methods: This cross-sectional study was performed within the framework of the diabetes prevention project in Isfahan. This study has been conducted during 2012-2013. Seventy-eight subjects participate, with an average age of 43.20 ± 5.29 years. Weight, height, waist and hip circumferences, blood pressure (BP) of participants, fasting plasma glucose, hemoglobin A1c, total cholesterol, high-density lipoprotein cholesterol, triglyceride (TG), and serum RBP4 were measured from fasting blood sample taken from each participant after an overnight fast (12-14 h)., Results: Systolic and diastolic BP were significantly higher in people in top median of RBP4 (11.8 ± 1.5 vs. 11.0 ± 1.2, P = 0.01 and 7.8 ± 1.0 vs. 7.3 ± 0.9, P = 0.03). Moreover, TG in people with high levels of RBP4 was higher compared with those with low levels of RBP4 (177.7 ± 97.6 vs. 138.7 ± 56.9, P = 0.02). People with low levels of RBP4 had significant greater hip circumferences (107.9 ± 7.5 vs. 104.3 ± 8.0, P = 0.04). There was no correlation between RBP4 and MS in crude model (odds ratio [OR]: 1.00, 0.95-1.05, P = 0.97). This null correlation remained after adjustment for body mass index, age, and physical activity (OR: 0.93, 0.91-1.07, P = 0.31)., Conclusion: Although RBP4 levels were positively association with some risk factors of MS including hip circumference, TG, and systolic and diastolic BP, it does not seem to be a valuable marker for identification of the MS in the first relative degree of diabetic patients., Competing Interests: There are no conflicts of interest.

Aims: First-degree relatives of patients with diabetes are at high risk for chronic diseases, including type 2 diabetes and obesity. Our purpose was to determine the effects of consuming 4 servings of legumes per week on lipid profiles, glycemic indices, and blood pressure of participants with family history of diabetes over 6 weeks of intervention., Methods: A total of 26 first-degree relatives of patients with diabetes (14 women and 12 men) participated in this randomized crossover clinical trial study. Participants were randomly assigned to a legume-enriched diet or habitual diet for 6 weeks. Paired t test and repeated measures analysis of variance were used to compare data for the 2 experimental diets., Results: The mean ± SE of legumes intake during the legume phase was 111.12 ± 10.53 g/day that was significantly higher (p < 0.001) than the amounts of legumes during habitual diet (50.73 ± 7.10 g/d). Percentage changes for cardiovascular disease risk factors did not change significantly following 6 weeks of legume consumption., Conclusions: Consumption of 4 servings of legumes per week had no significant effect on anthropometric measurements, glycemic indices, and lipid profiles of participants with family history of diabetes, though it could reduce systolic and diastolic blood pressure at a marginally significant level.

Objectives: Because of conflicting results of presented studies, the aim of this systematic review and meta-analysis of randomized clinical trials (RCTs) was to examine the effect of non-soy legume intake on inflammatory markers and C-reactive protein (CRP)., Methods: We searched Pubmed, ISI Web of Knowledge, SCOPUS, and Google Scholar for relevant studies up to July 2013, using medical subject headings [MeSH] and other related keywords. Nine RCTs were systematically reviewed to examine the effect of non-soy legume consumption on inflammatory markers. Eight studies involving 464 participants were included in the meta-analysis., Results: The results of the meta-analysis showed that non-soy legume consumption had a trend toward a significant effect on decreasing CRP and high-sensitivity (hs)-CRP concentrations (mean difference (MD) = -0.21; 95% confidence interval [CI], -0.44 to 0.02; P = 0.068). There was no overall effect of non-soy legume consumption on CRP or hs-CRP levels in either the parallel or crossover study designs. Our subgroup analysis of CRP type and study design, showed that non-soy legume intake had a significant effect on CRP levels in parallel studies (MD = -1.01; 95% CI, -1.78 to -0.23; P = 0.011) and a significant effect on hs-CRP levels (MD = -0.53; 95% CI, -0.95 to -0.11; P = 0.014) and in the crossover sub group (MD = -0.68; 95% CI, -1.28 to -0.08; P = 0.026)., Conclusions: This review of RCTs showed that non-soy legume consumption may contribute to reductions in CRP and hs-CRP concentrations. However, further controlled clinical trials are needed to investigate the effect of non-soy legume intake on other inflammatory markers., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Objective: First-degree relatives of patients with diabetes are at more risk for endothelial dysfunction and inflammation. The aim of the present study was to determine the effects of a non-soy legume-enriched diet on inflammatory biomarkers and serum adiponectin levels among first-degree relatives of these patients., Methods: Twenty-six participants (14 women and 12 men) with a family history of diabetes were recruited to this randomized, crossover study. Participants were randomly assigned to a legume-enriched or a habitual diet for 6 wk that was separated by a 2-wk washout. The inflammatory markers-high-sensitivity C-reactive protein (hs-CRP), interleukin-6, tumor necrosis factor-α, and serum levels of adiponectin-were measured at the beginning and the end of each intervention period according to the standard protocol., Results: Energy intake of participants was not statistically different between the two diets (1821.5 ± 100.11 versus 1788.2 ± 92.68 kcal/d, respectively). After consumption of a legume diet, percent change of hs-CRP reduced significantly compared with consumption of a habitual diet (-4.86% ± 1.86% versus 3.55% ± 1.97%, P = 0.002) and among the women in the study (-12.96% ± 1.96% versus 3.24% ± 2.65%, P = 0.004). The percent change of other inflammatory markers and serum concentrations of adiponectin were not significantly different between the two diet groups., Conclusion: The results of this study showed that a legume-enriched diet significantly reduced the hs-CRP concentrations in first-degree relatives of patients with diabetes after 6 wk of intervention compared with a habitual diet., (Copyright © 2015 Elsevier Inc.

Background: Leptin, a peptide contained 146 amino-acids, is mostly secreted from adipose tissue and it has a critical role on regulation of body weight, body fat mass, appetite, and food intakes. We tried to review the previous evidence regarding the effects of dietary intakes, including consumption of carbohydrates, fats and protein on concentrations of leptin concentration., Methods: We searched in PubMed search engine to January 2013 by using the following key words: dietary intake, diet, dietary fat, high-fat diet, dietary carbohydrate, high carbohydrate diet, dietary protein, high protein diet in combination with leptin, adipokine. Then, we recruited 35 articles to review in the present study., Results: It seems that beside the amount of fats, type of fatty acids have the key roles on circulating leptin concentration. Energy intake also significantly associated with the hormone. Studies regarding the association between carbohydrate intake and concentration of lepton have been reached to contradictory results. It seems that protein intake can increase the lepton activity., Conclusion: Findings from several studies suggest that a diet display an important role on change the concentration of lepton.

Objective: Both high and low birth weights (HBW and LBW) are risk factors for adulthood diseases. The aim of this study was to investigate the association of birth weight with cardiovascular disease (CVD) risk factors and mental problems among Iranian school-aged children., Methods: This national multicenter study of school-aged children entitled CASPIAN III was conducted among 5528 students in ranging from ages 10 to 18 y. Biochemical indices and anthropometric measurements were collected. Mental health was assessed by questionnaire. To investigate the association between birth weight categories and CVD risk factors and mental problems, multivariate logistic regression was used., Results: HBW adolescents were at higher risk for elevated diastolic blood pressure (DBP) (Ptrend < 0.05), low levels of high-density lipoprotein cholesterol (HDL-C) (Ptrend < 0.05), and lower risk for general obesity (Ptrend < 0.05) compared with the LBW category. HBW had no significant association with mental problems (Ptrend > 0.05) compared with LBW adolescents. The results of regression analysis, which considered normal birth weight as the reference group, showed that LBW students had lower risk for overweight and obesity (P < 0.01), as well as higher DBP (P < 0.05) but they were at higher risk for lower levels of HDL-C (P < 0.01). Furthermore, birth-weight categories had a U-shaped relationship with mental problems and sleep disorders (P < 0.05). Risk for confusion was higher among the LBW group (P < 0.05)., Conclusion: Findings from this population-based study revealed a positive relation between birth weight categories and CVD risk factors. Compared with students born with normal weight, those born with HBW and LBW were at higher risk for mental problems, sleep disorders, and confusion., (Copyright © 2014 Elsevier Inc.
