Abstract
OBJECTIVE Niacin is reported to decrease phosphorus concentration in maintenance hemodialysis (MHD) patients. Egg white is one of the main substitutable proteins in MHD patients due to its low phosphorus content. Therefore, we aimed to evaluate the effects of combined egg white and niacin supplementation on dialysis patients' serum phosphorus and nutritional biomarkers. DESIGN AND METHODS In this randomized controlled clinical trial, 98 patients on MHD were randomly allocated to four groups for 8 weeks: 24 g egg white (n = 25), 600 g niacin daily (n = 24), egg white combined with niacin (n = 24), and control (n = 24). Calcium, phosphorus, fibroblast growth factor-23, and other nutritional markers were assessed. RESULTS There was a significant difference among the groups only in phosphorus at the end of the trial, which was significantly lower in the niacin group (4.38 + 0.812 mg/dL) than in both the egg white (5.07 + 0.49 mg/dL) and egg white with niacin supplementation (5.41 + 0.662 mg/dL) groups. In this regard, albumin increased in egg white and egg white with niacin supplementation, while albumin did not change significantly in the niacin group. Urea reduction ratio and Kt/V rose only in the egg-white group, while aspartate aminotransferase increased only in the niacin and control groups. CONCLUSION Niacin decreases serum phosphorus concentration more than egg-white protein or a combined intervention. Egg white protein supplementation has beneficial effects on some nutritional statuses other than phosphorus control without the side effects of niacin.

Abstract
Rheumatoid arthritis (RA) is a systemic inflammatory autoimmune disorder with widespread synovitis. Isoflavones, the main active component of soy, have been reported to have potent anti-inflammatory effects; the previous RA animal models showed the promising effect of soy supplementation. We aimed to evaluate the effect of soy bread on inflammatory markers and lipid profiles in RA patients. The present study was designed as a randomized controlled trial. RA patients were randomly allocated to obtain soy bread (n = 22) or placebo bread (n = 22) for 8 weeks. Fasting serum levels of lipid profile, total antioxidant capacity (TAC), tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and DAS28 were checked. Findings showed that there were no significant differences between the two groups in physical activity and dietary intake at the beginning of the study and the end of the study. There were no significant differences between the two groups in measured lipid profile markers, including high-density lipoprotein, low-density lipoprotein, total cholesterol, triglyceride, and very low-density lipoprotein, at the end of the trial. In addition, TAC and CRP also were not significant at the end of the trial between the 2 groups (0.66 and 0.12, respectively). However, the serum levels of TNF-α reduced significantly in the soy bread group at the end of the intervention (p < 0.000) and compared with the control group (p < 0.019). Soy bread consumption only decreased circulating TNF-α serum concentration. Other outcome measures were not changed following supplementation. Future long-term, well-designed studies are needed to confirm these findings. Trial Registration Iranian Registry of Clinical Trials Identifier: IRCT20181021041396N1.

Abstract
This meta-analysis was conducted to examine the effects of watermelon supplementation on cardiovascular diseases (CVDs) risk factors in randomized controlled trials (RCTs). The comprehensive search was done in Cochrane Library databases, ISI Web of Science, PubMed, and Scopus up to March 2022. A random-effect model was used for computing weighted mean differences (WMD). Standard methods were applied to examine publication bias, sensitivity analysis, and heterogeneity. Of the 8962 identified studies, 9 RCTs were included in the final analysis. Watermelon consumption significantly decreased systolic blood pressure (SBP), total cholesterol (TC) and low-density lipoprotein (LDL). In addition, watermelon consumption led to a significant increase in fasting blood sugar (FBS). However, there was not any significant difference in other outcomes of interest including diastolic blood pressure (DBP), heart rate (HR), BMI, body fat, and serum levels of arginine, insulin, and CRP after watermelon supplementation. The current findings provide promising evidence of the antihypertensive effect of watermelon. However, due to the lack of evidence in human research, the result regarding the remaining outcomes needs to be used with caution. Furter RCTs with longer follow-ups and larger sample sizes should be done to confirm the current findings.

Abstract
Purpose Heat shock proteins (HSP-27) are reported to be involved in the pathophysiology of diabetes complications. The purpose of the current study is to assess the effects of eicosapentaenoic acid (EPA) supplementation on serum HSP-27, glycemic status and anthropometric indices in type 2 diabetes mellitus (T2DM) patients. Methods Thirty-six patients with T2DM were randomly allocated to obtain 2 g per day EPA (n = 18) or placebo (n = 18) for 8 weeks in a randomized, double-blind, placebo-controlled clinical trial. Fasting serum levels of HSP 27, fasting blood sugar, hemoglobin A1C, as well as anthropometric indices were measured. Results EPA supplementation reduces the serum level of HSP 27 in the EPA group compared with the placebo (P < 0.03). Although waist circumference (WC) decreased significantly in the EPA group at the end of the trial (P < 0.02), there was no significant difference in weight, WC, body mass index (BMI), and glycemic markers in both groups after intervention (P > 0.05). Conclusions We found that EPA supplementation reduces HSP 27 serum level in T2DM patients. However, future large-scale trials are needed.

Abstract
To evaluate the effects of pistachio consumption on the glucoregulatory status in individuals with a high risk of CVD, a systematic review and meta-analysis of randomised controlled trials (RCT) were conducted. Online databases including PubMed, Scopus, Web of Science and Cochrane Library were searched from inception until June 2019. Human trials that reported data for fasting blood sugar (FBS), fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) were included. Data were pooled using the random effect models and expressed as weighted mean difference (WMD) with 95 % CI. Eight RCTs were included in the analyses. Pistachio consumption, exchanged isocalorically for other foods, decreased FBS (WMD: -5·32 mg/dl, 95 % CI (-7·80, -2·64), P < 0·001) and insulin (WMD: -1·86 µIU/ml, 95 % CI (-3·13, -0·59), P < 0·01) concentrations in individuals with a high risk of CVD. However, no changes were observed in the levels of HOMA-IR between the groups (WMD: -0·66, 95 % CI (-1·89, 0·58), P = 0·30). Pistachio consumption may improve glucoregulatory status in individuals at risk for CVD, as evidenced by reduced FBS and insulin concentrations. However, due to the limited availability of studies with diabetic cases and relatively small sample sizes of available studies, well-designed trials with adequate sample sizes aimed at diabetic populations are recommended.

Abstract
INTRODUCTION Metabolic syndrome and its components are major health concerns around the world. Among various factors, overweight/obesity, its consequent inflammation, and hypertension are of special importance. Plums are anti-oxidant-rich fruits which have long been investigated for their health benefits. In this systematic review and meta-analysis, we investigated the possible impact of plum supplementation on obesity, inflammation, and blood pressure. METHODS All of the major databases (PubMed, Scopus, Cochrane, and Web of Science, Google Scholar and EMBASE) were searched to obtain the articles eligible for the review. Relevant data was extracted for the final analysis. Weighted mean difference (WMD) was obtained using fixed and random effect models. The main outcomes included systolic and diastolic blood pressure, body weight, body mass index (BMI), body fat percentage, waist circumference (WC) and blood C-reactive protein (CRP) levels. The effect sizes were expressed as weighted mean difference (WMD) and 95% confidence intervals (CI). RESULTS Crude search provided 3121 articles, among which 11 were eligible to be included. After crude and subgroup analysis, we were unable to detect any significant impact of plum supplementation on body weight (weight mean difference (WMD) of 0.04 kg; 95% CI: -1.55, 1.63, p = 0.959), BMI (WMD 0.39 kg/m2; 95% CI: -0.11, 0.90, p = 0.125), body fat percentage (WMD = 0.59%; 95% CI: -0.41, 1.59, p = 0.249), waist circumference (WMD = 0.60 cm; 95% CI: -1.83, 3.04, p = 0.627), systolic blood pressure (WMD -1.24 mmHg; 95% CI: -3.08, 0.59, p = 0.185), diastolic blood pressure (WMD -4.32 mmHg (95% CI: -9.29, 0.65, p = 0.089), or inflammation indicated by C-reactive protein (CRP) levels (WMD = 0.23 mg/l; 95% CI: -0.27, 0.73, p = 0.371). CONCLUSION Our results show that plum supplementation has no positive effect on factors of metabolic syndrome. We recommend that further research in the form of clinical trials be conducted to make a clear conclusion as of the effectiveness of plum supplementation on parameters of metabolic syndrome.

Abstract
We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the effects of consuming pistachio nuts on lipid profiles (total cholesterol [TC], low-density lipoprotein cholesterol [LDL-C], high-density lipoprotein cholesterol [HDL-C], and triglyceride [TG]). Databases of PubMed, Scopus, ISI Web of Science, and Cochrane Library were searched from inception to June 2019 to identify RCTs documenting the effects of consuming pistachio nuts on blood lipid profiles in adults. Effect sizes were reported as weighted mean difference (WMD) and 95% confidence interval (CI) using the random-effects models (DerSimonian-Laird method). Twelve eligible RCTs were included. Consumption of pistachio nuts decreased TC (WMD: -7.48 mg/dL; 95% CI, -12.62 to -2.34), LDL-C (WMD: -3.82 mg/dL; 95% CI, -5.49 to -2.16) and TG (WMD: -11.19 mg/dL; 95% CI, -14.21 to -8.17) levels. However, HDL-cholesterol levels (WMD: 2.45 mg/dL; 95% CI, -2.44 to 7.33) did not change following pistachio consumption. Consuming pistachio nuts may improve lipid profiles (TC, LDL-C, TG) in adults and may be protective against cardiometabolic diseases. However, further studies with larger sample sizes are required to confirm these results.

Abstract
Number trials have evaluated the effect of almond intake on glycemic control in adults; however, the results remain equivocal. Therefore, the present meta-analysis aims to examine the effectiveness of almond intake on glycemic parameters. Online databases including PubMed, Scopus, ISI web of science, Embase, and Cochrane Library were searched up to August 2021 for trials that examined the effect of almond intake on glycemic control parameters including fasting blood sugar (FBS), insulin, HOMA-IR, and HbA1C. Treatment effects were expressed as mean difference (MD) and the standard deviation (SD) of outcomes. To estimate the overall effect of almond intake, we used the random-effects model. In total, 24 studies with 31 arms were included in our analysis. The meta-analysis revealed that almond intake did not significantly change the concentrations of FBS, HbA1c, insulin levels, and HOMA-IR. In conclusion, there is currently no convincing evidence that almonds have a clear beneficial effect on glycemic control. Future studies are needed before any confirmed conclusion could be drowned.

Abstract
The high prevalence rate in conjunction with the long latency period made prostate cancer (PCa) an attractive and reasonable candidate for preventive measures. So far, several dietary and nutritional interventions have been implemented and studied with the aim of preventing the development or delaying the progression of PCa. Calorie restriction accompanied by weight loss has been shown to be associated with decreased likelihood of aggressive PCa. Supplements have played a major role in nutritional interventions. While genistein and lycopene seemed promising as preventive agents, minerals such as zinc and selenium were shown to be devoid of protective effects. The role of vitamins has been widely studied, with special emphasis on vitamins with antioxidant properties. Data related to Vitamin A and Vitamin C were rather controversial and positive effects were of insignificant magnitude. Vitamin E was associated with a decreased risk of PCa in high-risk groups like smokers. However, when it comes to Vitamin D, the serum levels might affect the risk of PCa. While deficiency of this vitamin was associated with increased risk, high serum levels imposed the risk of aggressive disease. Despite the seemingly promising effects of dietary measures on PCa, no firm recommendation could be made due to the limitations of the studies and evidence. However, the majority of these advices could be followed by the patients with the intent of living a healthy lifestyle.

Abstract
This systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted to determine the effects of grapes and grape products on inflammation and oxidative stress among adults. PubMed, Scopus, ISI Web of Science, and Cochrane Library databases were searched up to July 2020 to identify RCTs investigating the effects of grape and grape products on inflammatory and oxidative stress markers. Weighted mean differences (WMD) were pooled using a random-effects model. Of the 8,962 identified studies, 24 RCTs (27 arms) were included in the statistical analysis. Grape products significantly reduced serum C-reactive protein (CRP) levels (WMD: -0.35 mg/L; 95% CI: -0.62, -0.09, p = .008), but they had no significant effect on serum tumor necrosis factor-alpha (TNF-α) (WMD = -1.08 pg/ml; 95% CI: -2.29, 0.11, p = .07), interleukin-6 (IL-6) (WMD = 0.13 pg/ml; 95% CI: -0.35, 0.60, p = .60), total antioxidant capacity (TAC) (WMD = 0.15; 95% CI: -0.35, 0.65, p = .54), or malondialdehyde (MDA) (WMD = 0.14; 95% CI: -0.64, 0.92, p = .72). The analysis indicated possible decreasing effects of grapes and grape products on CRP, but they might not be able to change IL-6, TNF-α, TAC, and MDA concentrations. Nonetheless, further studies are warranted before definitive conclusions may be reached.

Abstract
This systematic review and meta-analysis of randomized controlled trials (RCTs) was conducted to summarize the effect of almond intake on anthropometric indices in adult subjects. We searched PubMed, Scopus, ISI Web of Science, Cochrane Library, and Google Scholar databases until January 2020 to identify relevant RCTs. Data were reported as weighted mean differences (WMDs) and standard deviations (SDs) to show the magnitude of effects of almond on body weight (BW), body mass index (BMI), waist circumference (WC), fat mass (FM), and fat-free mass (FFM). Out of 2983 reports, 28 RCTs (37 arms) were eligible for including in our meta-analysis. The pooled results, obtained using a random-effects model, showed that almond intake significantly decreased BW (WMD: -0.38 kg, 95% CI: -0.65, -0.10, p = 0.007, I2 = 30.5%) and FM (WMD: -0.58 kg, 95% CI: -0.87, -0.28, p < 0.001, I2 = 4.9%). However, we found no significant effect of almond administration on BMI (WMD: -0.30 kg m-2, 95% CI: -0.67, 0.06, p = 0.101, I2 = 62.6%), WC (WMD: -0.60 cm, 95% CI: -1.28, 0.06, p = 0.078, I2 = 0.0%), and FFM (WMD: 0.23 kg, 95% CI: -0.04, 0.50, p = 0.097, I2 = 49.5%). Overall, the current meta-analysis demonstrated that resveratrol almond intake significantly reduced weight and FM, but did not affect BMI, WC, and FFM. Further studies are still required to confirm our results.

Abstract
The aim of this study was to perform a systematic review and meta-analysis of randomized clinical trials (RCTs) to examine the effect of grapes/grape products supplementation on glycemic indices in adults. Our systematic search to find relevant RCTs was performed up to February 2020 using PubMed, Scopus, ISI Web of Science, Cochrane Library, and Google Scholar. Based on the heterogeneity between included studies, a random effects or a fixed model was applied in the meta-analysis, and results were expressed as weighted mean differences (WMD) with 95% confidence intervals (CI). Twenty-nine clinical trials (1,297 participants) fulfilled the eligibility criteria of the present meta-analysis. Overall, the grapes/grape products supplementation significantly reduced homeostatic model assessment of insulin resistance (HOMA-IR) (WMD: -0.54, 95% CI: -0.91, -0.17, p = . 004) but did not affect fasting insulin levels (WMD: -0.90 μIU/ml, 95% CI: -1.04, 2.84, p = .362) and hemoglobin A1C (Hb1Ac) percentage (WMD: 0.00%, 95% CI: -0.10, 0.11, p = . 916) in the main analyses. In addition, changes to fasting blood glucose (FBG) levels were in favor of the control group (WMD: 1.19 mg/dl, 95% CI: 0.05, 2.34, p = .041). We found that giving grapes/grape products to adults might have beneficial effects on the HOMA-IR. Further, large-scale RCTs with longer duration are required to confirm these results.

Abstract
A number of clinical trials have examined the effect of almond intake on lipid profile in recent years; however, the results remain equivocal. Therefore, the present study aims to summarize and quantitatively examine the available evidence on the effectiveness of almond intake on lipid parameters by employing a systematic review and meta-analytic approach. Online databases including PubMed, Scopus, Embase, and Cochrane Library were searched up to September 2020 for randomized controlled trials that examined the effect of almond intake on lipid profile in adults. Treatment effects were expressed as weighted mean difference (WMD) and the corresponding standard error (SE) in the concentrations of serum lipids. To estimate the overall effect of almond intake, we employed the random-effect model. In total, 27 studies with 36 effect sizes were included in our analysis (1154 cases and 904 control subjects). The meta-analysis revealed that almond intake significantly changed the concentrations of triglycerides (WMD = -6.68 mg dL-1; 95% CI: -11.62, -1.75, p = 0.008), total cholesterol (WMD = -4.92 mg dL-1; 95% CI: -7.81, -2.03, p = 0.001), and low-density lipoproteins (WMD = -5.65 mg dL-1; 95% CI: -8.75, -2.55, p < 0.001); however it did not have a significant effect on high-density lipoprotein (WMD = -0.21 mg dL-1; 95% CI: -1.26, 0.84, p = 0.697) levels. Meta-regression analysis indicated a linear relationship between the dose of almond and change in TG (P = 0.021). This meta-analysis concludes that almond intake can significantly reduce lipid parameters. To draw straightforward conclusions regarding generalized recommendations for almond intake for improving lipid profile, there is a need for more well-controlled trials exclusively targeting patients with dyslipidaemia.

Abstract
In this study, we aimed to systematically review the literature to evaluate the effects of magnesium (Mg) supplementation on blood pressure (BP) and obesity measure among patients with type 2 diabetes mellitus (T2DM). Major electronic databases of Web of Science, the Cochrane library, PubMed, and Scopus were searched completely from the inception until 15 October 2019 to identify randomized clinical trials (RCTs) pertaining to the topic of interest. All outcomes were pooled using a random-effects model and expressed as weighted mean differences (WMD) with 95% confidential intervals (CI). Heterogeneity, sensitivity analysis, and publication bias were also assessed using standard methods. The pooled analysis of five RCTs showed that Mg supplementation did not affect body weight (WMD: - 0.01 kg, 95% CI: - 0.36 to 0.33), BMI (WMD: - 0.07, 95% CI: - 0.18 to 0.04), and waist circumference (WMD: 0.12, 95% CI: - 1.24 to 1.48) in T2DM patients compared to the control groups of the patients who received placebo. However, pooling seven RCTs together showed significant reduction of systolic blood pressure (WMD: - 5.78 mmHg, 95% CI: - 11.37 to - 0.19) and diastolic blood pressure (WMD: - 2.50 mmHg, 95% CI: - 4.58 to - 0.41) in T2DM patients. Furthermore, subgroup analysis by dose of intervention, intervention duration, and type of intervention suggested that Mg supplementation for > 12 weeks, in doses higher than 300 mg/day or inorganic forms, could significantly decrease both systolic and diastolic BP in T2DM patients. Based on the findings, Mg supplementation has beneficial effects on BP in type 2 diabetes patients independent of body weight status. However, further investigations are needed to provide more reliable evidences.

Abstract
BACKGROUND Soy products contain several compounds with anti-inflammatory properties like genistein and daidzein which reported to act through different pathways. Present study conducted considering the inconsistent results and lack of any comprehensive review regarding randomized controlled trials which assess the effect of soy products on inflammatory markers. METHODS Following electronic databases were searched up to March 2020: PubMed, Scopus, ISI web of science, and Cochrane Library All randomized trials which assessed the effect of soy product supplementation on c-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were included for last analysis. Treatment effects were expressed as mean difference (MD) and the standard deviation (SD) of outcomes. To estimate the overall effect the random-effects model was employed. RESULTS Finally, 51 randomized trial were included for present study. Last analysis showed that soy product supplementation lead to significant reduction in CRP (MD -0.27 mg/L; 95% CI: -0.51, -0.02, p = 0.028) but it did not affect IL-6 (MD 0.0 pg/ml; 95% CI: -0.06, 0.06, p = 0.970) and TNF-α (MD = -0.04 pg/ml; 95% CI: -0.11, 0.03, p = 0.252). Subgroup analysis showed that soy supplementation had a significant impact on decreasing IL-6 and TNF-α levels when studies had a long-term intervention (≥12 weeks) and used low dose isoflavone (<100 mg/day). CONCLUSION In conclusion, present systematic review and meta-analysis found a significant reduction in CRP levels after soy supplementation whiles IL-6 and TNF-α did not affect.

Abstract
Decreased sperm motility is one of the main causes of male infertility. The aim of this study was to evaluate the effects of probiotic supplementation on semen quality, seminal oxidative stress biomarkers, inflammatory factors and reproductive hormones. In this randomised, double-blind controlled clinical trial, 52 men with idiopathic oligoasthenoteratozoospermia attending a urology clinic, were randomly assigned to either an intervention or placebo (n = 26) group. This investigation was registered by the identification code of IRCT20141025019669N7 in the clinical trials registry of Iran. The Intervention group took 500 mg of Probiotics daily and the placebo group took a daily placebo for 10 weeks. Semen parameters, total antioxidant capacity, malondialdehyde, inflammatory factors and reproductive hormones were measured at baseline and at the end of the study. After the intervention, ejaculate volume, number, concentration and the percentage of motile sperm, total antioxidant capacity of plasma significantly increased and the concentration of plasma malondialdehyde and inflammatory markers significantly decreased in the intervention group. Probiotic supplementation in infertile men lead to a significant increase in sperm concentration and motility and a significant reduction in oxidative stress and inflammatory markers. Therefore, oral intake of probiotics has the potential to be one of the ways to deal with oxidative damage of sperm.

Abstract
The relationship between thyroid hormones metabolism and trace element levels has biological plausibility; however, previous reports that compared trace element levels in patients with hypothyroidism and healthy individuals yielded conflicting results. Therefore, the aim of this meta-analysis was to investigate the association between selected trace elements (i.e., selenium (Se), zinc (Zn), iron (Fe), manganese (Mn), copper (Cu), lead (Pb)), and magnesium (Mg) concentrations in patients with hypothyroidism and healthy controls. Electronic databases, including PubMed, Scopus, Embase, and Science Direct, were searched systematically until September 2019. Thirty-two observational studies were included in the final analyses. Hedges' g tests were used to estimate effect sizes, as trace element concentrations were reported using different measurement units across the studies. Selenium (Hedges' g = - 0.52; 95% CI = [- 1.05, - 0.002]; P = 0.049) and Zn (Hedges' g = - 0.86; 95% CI = [- 1.66, - 0.06]; P = 0.035) concentrations were significantly lower, whereas Pb concentrations were significantly higher (Hedges' g = 0.34; 95% CI = [0.10, 0.59]; P = 0.006) in patients with hypothyroidism compared with healthy controls. There were no differences in the concentrations of Fe, Cu, Mn, and Mg between the groups. Patients with hypothyroidism exhibited lower Se and Zn and increased Pb concentrations compared with healthy controls. High-quality studies with larger sample sizes are required to explicate the link between trace element status and hypothyroidism.

Abstract
AIM This study was designed to make a systematic review and meta-analysis on randomized controlled trials (RCTs) assessing the effect of cinnamon on blood pressure (BP). METHODS A systematic computerized literature search of PubMed, Scopus, Web of Science, Cochrane Library and Google Scholar databases was conducted up to August 2019. All RCTs using cinnamon supplements in adults were included in this systematic review and meta-analysis. RESULTS Out of 927 records, 8 trials that enrolled 582 participants were included. The pooled effect size showed that SBP did not change following cinnamon supplementation. (WMD: -0.61mmHg; 95% CI: -1.36, 0.14, P= 0.111). Also cinnamon supplementation in long-duration (≥ 8weeks) had a significant effect on SBP (WMD: -1.25 mmHg; 95% CI: -2.22, -0.28, P= 0.012). Pooled analysis showed that cinnamon had a significant effect on DBP (WMD: -0.93mmHg, 95% CI: -1.55 to -0.32, P= 0.003). In addition, results from both duration subsets and high dose (>1500 mg/day) of cinnamon supplementation were significant. CONCLUSION Our findings revealed that cinnamon supplementation has favorable effects on DBP although results of SBP were not the same. Nonetheless, further studies are required.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fenugreek is a traditional herbal medicine that has been used for centuries to treat hyperglycemia, muscle spasms, gastritis, constipation, edema, and other metabolic disorders. Recently, lipid-lowering effects of fenugreek have been identified. AIM OF THE STUDY The aim of this systematic review and meta-analysis was to determine and clarify the impact of fenugreek supplementation on anthropometric indices and serum lipid levels. MATERIALS AND METHODS We searched PubMed, Scopus, ISI Web of Science, Cochrane Library, and Google Scholar from inception to June 2019 using relevant keywords. All randomized controlled trials (RCTs) investigating the effects of fenugreek on anthropometric indices and plasma lipids in adults were included. A random-effects model was used for quantitative data synthesis. A sensitivity analysis was conducted using the leave-one-out method. RESULTS A meta-analysis of 12 RCTs (14 arms) with 560 participants suggested a significant decrease in plasma concentrations of total cholesterol (WMD = -9.371 mg/dL; 95% CI: -15.419, -3.323, p = 0.002), triglycerides (WMD = -13.776 mg/dL; 95% CI: -26.636, -0.916, p = 0.036), and low density lipoprotein cholesterol (WMD = -6.590 mg/Dl; 95% CI: -13.042, -0.137, p = 0.045), as well as an increase in plasma high density lipoprotein cholesterol (WMD = 3.501 mg/dL; 95% CI: 1.309, 5.692, p = 0.002), while body weight (WMD = 0.223 kg; 95% CI: -0.509, 0.955, p = 0.551) and body mass index (WMD = 0.091 kg/m2; 95% CI: -0.244, 0.426, p = 0.596) were not altered. CONCLUSION Fenugreek supplementation improved lipid parameters in adults. However, to confirm these results, more studies, particularly among hyperlipidemic patients, are needed.

Abstract
Background In the literature, there are still controversies regarding the effect of phytosterol(PS) supplementation on fasting blood sugar (FBS), insulin levels and glycosylated hemoglobin (HbA1c) in humans. We aimed to assess the impact of PS supplementation on FBS, HbA1c and insulin levels by conducting a systematic review and meta-analysis of the available randomized controlled trials (RCTs). Methods A comprehensive search was conducted to identify all RCTs published up to May 2019 in the following databases: PubMed-MEDLINE, Web of Science, Cochrane Library and Scopus. The mean difference with 95% confidence intervals (CIs) was pooled using a random-effects model (DerSimonian-Laird method). Results Twenty-six arms from 20 RCTs were included in the present meta-analysis. Our findings show that PS supplementation decreases insulin levels (mean difference [MD]: -6.426 μU/ml, 95% CI: -7.187, -5.665, P- value = 0.000). However, PS supplementation did not have significant effects on FBS and HbA1c levels. Following PS supplementation, significant changes in FBS (mean difference [MD]: -1.942 mg/dl, 95% CI: -3.637, -0.246, P- value = 0.025) and HbA1c (mean difference [MD]: -0.059%, 95% CI: -0.114, -0.004, P- value = 0.035) based on PS dosage (mg/d) were recorded. Conclusions In patients with a baseline BMI <25 kg/m2, PS consumption significantly increased FBS levels. Patients who consumed 1-2 g/day of PS had a lower FBS and lower HbA1c levels.

Abstract
OBJECTIVE The present systematic review and meta-analysis aimed determine the efficacy of almond intake on blood pressure (BP). METHODS PubMed, Scopus, ISI Web of Science, Cochrane library and Google Scholar were comprehensively searched to infinity until December 2019. Randomized clinical trials (RCTs) reporting effects of almond intake on aortic and brachial BP were included. Weighted mean differences (WMDs) were pooled using a random-effects model. Standard methods were used for assessment of heterogeneity, sensitivity analysis, and publication bias. RESULTS A total of 16 RCTs (1128 participants) were included in the meta-analysis. Pooled analysis suggested that almond intake can reduced diastolic BP (DBP) (WMD = -1.30 mmHg; 95 % CI: -2.31,-0.30, p = 0.01, I2 = 0.0 %). However, there was not any impact of almond intake on systolic BP (SBP) (WMD = -0.83 mmHg; 95 % CI: -2.55, 0.89, p = 0.34, I2 = 58.9 %). Subgroup analysis revealed a significant reduction in SBP levels in subjects with lower SBP and lower dose of almonds. CONCLUSION We found that almonds might have a considerable favorite effect in BP and especially in DBP, and it could be encouraged as part of a healthy diet; however due to the high calorie content, the intake should be part of healthy diet.

Abstract
Different adipokines secreted from adipose tissue, exert a range of physiological effects. The aim of present systematic review and meta-analysis was to critically investigate the consequence of bariatric surgery on circulating adipokines, that is, adiponectin, leptin, visfatin, resistin, plasminogen activator inhibitor, and chemerin. After systematically checking the following electronic databases: ISI web of Science, Scopus and PubMed without limitation in time and language up to February 2019, a pool based on a random effect model was established. Eighty-five eligible studies were entered for quantitative analysis. Our meta-analysis revealed that circulating adiponectin increased significantly after bariatric surgery [Standardized mean difference (SMD)=1.401, 95% CI: 1.101, 1.701, p<0.001]; whilst leptin (SMD=-2.178, 95% CI: -2.433, -1.923, p<0.001), PAI-1 (-14.928 ng/ml 95% CI: -21.794, -8.063, p<0.001), and chemerin (-50.238 ng/ml 95% CI: -85.708, -14.768, p<0.001) decreased. However, serum visfatin (2.05 ng/ml, 95% CI: -5.07, 9.17, p=0.573) and resistin (-2.080 ng/ml, 95% CI: -5.352, 1.192, p=0.21) were unchanged. In conclusion, bariatric surgery is associated with a reduction in specific adipokines including leptin, chemerin, and PAI-1, whereas adiponectin is raised, adaptations that could be indicative of improved fat mass and function.

Abstract
Background:
Adiponectin, a well-known adipokine plays a number of regulatory actions
in human body metabolism. Decreased levels of adiponectin have been reported in type 2 diabetes
mellitus, cardiovascular diseases, metabolic syndrome and hypertension. Coenzyme Q10 (Co Q10)
is a fat-soluble antioxidant substance which has been reported to be effective in several metabolic
disturbances such as insulin resistance and inflammation.
Objective:
Present systematic review and meta-analysis were performed to assess the effects of
CoQ10 supplementation on adiponectin serum level.
Methods:
A comprehensive search was performed in electronic databases including EMBASE,
Google scholar, and PubMed up to January 2018. A meta-analysis of eligible studies was performed
using random effects model to estimate pooled effect size of CoQ10 supplementation on adiponectin.
Results:
A total of 209 subjects were recruited from 5 eligible studies. Meta-analysis did not suggest
any significant effect of CoQ10 supplementation on adiponectin serum level (0.240 mg/dl,
95%CI: -0.216, 0.696, P= 0.303), without significant heterogeneity between included studies (I2=
40.9%, p= 0.149).
Conclusion:
Although present meta-analysis did not indicate any significant effects of CoQ10 supplementation
on serum adiponectin levels but future long-term dose-response trials are needed before
any firm conclusion.

Abstract
Background:Anthracyclines are widely used chemotherapeutic agents in several cancers. Since its use, survival improved significantly among cancer patients and has been reported to be up to 80%. However, anthracyclines possess several cardiac, renal and hematological toxicities which limit their use in practice. Cardiotoxicity is still the most important and dose-limiting side effect of anthracycline treatment. Here we aimed to investigate the frequency of anthracyclineinduced cardiomyopathy in pediatric malignancies in Khuzestan Province, Iran.Methods:A total of 112 patients were enrolled in the present study. Patients were allocated to the case or control group based on receiving anthracycline. Echocardiographic examinations were performed by a cardiologist. Electrocardiograms were also recorded.Results:We showed that cancer patients who underwent anthracycline treatment showed cardiomyopathy as defined by lower LVEF (Left Ventricular Ejection Fraction) among patients (p = 0.041). Abnormal LVEF was reported with a frequency of about 9.5% in patients (p = 0.026). However, LVFS (Left Ventricular Fraction Shortening), QRS voltage and QT interval did not differ significantly between treatment and control groups. Our data analysis revealed that this difference is mainly related to high cumulative dose since high cumulative dose of anthracycline (>300 mg/m2) leads to lower LVEF and LVFS and higher QRS voltage in comparison with lower cumulative dose (<300 mg/m2) and control group; but there was no significant difference between low dose and control group. Different age groups and type of malignancy including hematological and solid tumors did not show any significant differences for echocardiographic and electrocardiograms parameters.Conclusion:In our study, lower LVEF among patients who received anthracyclines were mainly related to a high cumulative dose of anthracyclines, which emphasizes the effect of cumulative dose for cardiotoxic effects. Larger studies are needed to investigate possible other risk factors for cardiotoxicity.

Abstract
Several reports have indicated a positive effect of phytosterols on blood pressure (BP), nevertheless these findings have been controversial. Therefore, a systematic review and meta-analysis of randomized controlled trials (RCTs) was aimed to investigate the effects of phytosterol supplementation on BP. An online search was carried out in PubMed, Scopus, ISI Web of Science, Cochrane library and Google Scholar up to May 2019. Weighted Mean difference (WMD) with 95% confidence intervals (CIs) were calculated using a fixed-effects model. The present meta-analysis of 19 RCTs showed that supplementation with phytosterols can decrease both systolic BP (WMD: -1.55 mmHg, 95% CI: -2.67 to -0.42, p = 0.007) and diastolic BP (WMD: -0.84 mmHg, 95% CI: -1.60 to -0.08, p = 0.03). Dose-response analysis revealed that phytosterol intake change SBP significantly based on treatment dose in nonlinear fashion. Subgroup analysis based on duration showed a significant effect of phytosterol on SBP and DBP in subsets of <12 weeks. In addition, a significant effect of phytosterol was observed in dosage of ≥2000 mg for SBP and <2000 mg for DBP. Based on current findings supplementation with phytosterol may be a beneficial adjuvant therapy in hypertensive patients as well as a complementary preventive option in prehypertensive and normotensive individuals. However, this issue is still open and requires further investigation in future studies.

Abstract
PURPOSE Present systematic literature review and dose-response meta-analysis were carried out to evaluate the association between sleep duration and sarcopenia risk. METHODS Related studies were found by searching ISI Web of science databases, Scopus, and PubMed, up to May, 2019. Data were available from four studies. A total odds ratio of 17551 participants in these studies was pooled for the current study. RESULTS Pooled outcomes from random effects model demonstrated that lowest category of sleep duration (under 6 h) versus reference category (6-8 h) was significantly related with increased risk of sarcopenia (OR: 1.71 95% CI, 1.11, 2.64). Pooled OR also indicated that highest category (more than 8 h) of sleep duration versus reference category (6-8 h) was significantly associated with increased risk of sarcopenia (OR: 1.52 95% CI, 1.23, 1.88). Moreover, subgroup analysis by sex showed that women were affected by both short and long sleep while men were only affected by long sleep duration. The nonlinear dose-response meta-analysis revealed a U-shaped association between sleep duration and the risk of sarcopenia, with a nadir at 8 h per day. The linear dose-response meta-analysis illustrated that the risk of sarcopenia did not change significantly nor for a 0.5-h increment neither for 1-h increment in sleep duration per day. CONCLUSION The outcomes from this meta-analysis indicate that the public should be made aware of the negative consequences of long and short sleep for sarcopenia especially among women. Further studies should now be undertaken to establish possible links between risk of sarcopenia and sleep duration.

Abstract
Cardiovascular disease is a highly prevalent issue worldwide and one of its main manifestations, dyslipidemia, needs more attention. Recent studies have suggested that cardamom has favorable effects beyond lipid lowering, but the result are contradictory. Our objective was to conduct a systematic review and meta-analysis on randomized controlled trials (RCTs) that assessed the effect of cardamom on lipids. The search included PubMed, Scopus, ISI Web of Science, Google Scholar, and the Cochrane library (up to March, 2019) to identify RCTs investigating the effects of cardamom supplementation on serum lipid parameters. Weighted mean differences (WMDs) were pooled using a random-effect model. Meta-analysis of data from five eligible RCTs showed that cardamom supplementation did not significantly change the concentrations of total cholesterol (WMD: -6.11 mg/dl, 95% CI [-13.06, 0.83], I2 = 0.0%), low-density lipoprotein cholesterol (WMD: -4.31 mg/dl, 95% CI [-9.75, 1.13], I2 = 0.0%), or high-density lipoprotein cholesterol (WMD: 1.75 mg/dl, 95% CI [-1.95 to 5.46], I2 = 71.4%). However, a significant reduction was observed in serum triglyceride (TG; WMD: -20.55 mg/dl, 95% CI [-32.48, -8.63], I2 = 0.0%) levels after cardamom supplementation. Cardamom might be able to change TG, but for confirming the results, more studies exclusively on dyslipidemia patients and considering the intake of lipid lowering agents as exclusion criteria are necessary.

Abstract
BACKGROUND AND AIM l-carnitine has an important role in fatty acid metabolism and could therefore act as an adjuvant agent in the improvement of dyslipidemia. The purpose of present systematic review and meta-analysis was to critically assess the efficacy of l-carnitine supplementation on lipid profiles. METHODS AND RESULTS We performed a systematic search of all available randomized controlled trials (RCTs) in the following databases: Scopus, PubMed, ISI Web of Science, The Cochrane Library. Mean difference (MD) of any effect was calculated using a random-effects model. In total, there were 55 eligible RCTs included with 58 arms, and meta-analysis revealed that l-carnitine supplementation significantly reduced total cholesterol (TC) (56 arms-MD: -8.53 mg/dl, 95% CI: -13.46, -3.6, I2: 93%), low-density lipoprotein-cholesterol (LDL-C) (47 arms-MD: -5.48 mg/dl, 95% CI: -8.49, -2.47, I2: 94.5) and triglyceride (TG) (56 arms-MD: -9.44 mg/dl, 95% CI: -16.02, -2.87, I2: 91.8). It also increased high density lipoprotein-cholesterol (HDL-C) (51 arms-MD:1.64 mg/dl, 95% CI:0.54, 2.75, I2: 92.2). l-carnitine supplementation reduced TC in non-linear fashion based on dosage (r = 21.11). Meta-regression analysis indicated a linear relationship between dose of l-carnitine and absolute change in TC (p = 0.029) and LDL-C (p = 0.013). Subgroup analyses showed that l-carnitine supplementation did not change TC, LDL-C and TG in patients under hemodialysis treatment. Intravenous l-carnitine and lower doses (>2 g/day) had no effect on TC, LDL-C and triglycerides. CONCLUSION l-carnitine supplementation at doses above 2 g/d has favorable effects on patients' lipid profiles, but is modulated on participant health and route of administration.

Abstract
BACKGROUND AND AIM Although some earlier studies have indicated the effect of phytosterol (PS) supplementation on serum lipoprotein(a) (Lp(a)) and free fatty acid (FFA) concentration, findings are still conflicting. We aimed to assess the impact of PS supplementation on serum Lp(a) and FFA concentration through a systematic review and meta-analysis of available RCTs. METHODS AND RESULTS We performed a systematic search of all available RCTs conducted up to 21 February 2019 in the following databases: PubMed, Scopus, and Cochrane. The choice of fixed- or random-effect model for analysis was determined according to the I2 statistic. Effect sizes were expressed as weighted mean difference (WMD) and 95% confidence interval (CI). Pooling of 12 effect sizes from seven articles revealed a significant reduction of Lp(a) levels following PS supplementation (MD: -0.025 mg/dl, 95% CI: -0.045, -0.004, p = 0.017) without significant heterogeneity among the studies (I2 = 0.0%, p = 0.599). Also, PS supplementation significantly lowered FFA (MD: -0.138 mg/dl, 95% CI: -0.195, -0.081, p = 0.000) without significant heterogeneity among the studies (I2 = 0.0%, p = 0.911). The results for meta-regression and sensitivity analysis were not significant. CONCLUSION The meta-analysis suggests that oral PS supplementation could cause a significant reduction in serum Lp(a) and FFA.

Abstract
Introduction: Risk of diabetes mellitus type 2 (T2DM) is variable between individuals due to different metabolic phenotypes. In present network meta-analysis, we aimed to evaluate the risk of T2DM related with current definitions of metabolic health in different body mass index (BMI) categories.
Methods: Relevant articles were collected by systematically searching PubMed and Scopus databases up to 20 March 2018 and for analyses we used a random-effects model. Nineteen prospective cohort studies were included in the analyses and metabolically healthy normal weight (MHNW) was considered as the reference group in direct comparison for calculating indirect comparisons in difference type of BMI categories.
Results: Total of 199403 participants and 10388 cases from 19 cohort studies, were included in our network meta-analysis. Metabolically unhealthy obesity (MUHO) group poses highest risk for T2DM development with 10 times higher risk when is compared with MHNW (10.46 95% CI; 8.30, 13.18) and after that Metabolically unhealthy overweight (MUOW) individuals were at highest risk of T2DM with 7 times higher risk comparing with MHNW (7.25, 95% CI; 5.49, 9.57). Metabolically healthy overweight and obese (MHOW/MHO) individuals have (1.77, 95% CI; 1.33, 2.35) and (3.00, 95% CI; 2.33, 3.85) risk ratio for T2DM development in comparison with MHNW respectively.
Conclusion: In conclusion we found that being classified as overweight and obese increased the risk of T2DM in comparison with normal weight. In addition, metabolically unhealthy (MUH) individuals are at higher risk of T2DM in all categories of BMI compared with metabolically healthy individuals.

Abstract
BACKGROUND AND AIM Hypertension is a chronic condition that can lead to several health problems, such as cardiovascular diseases, myocardial infarction, stroke, retinopathy and renal failure. In the present study, a systematic review and meta-analysis was undertaken with the main aim of estimating the quantitative effect of curcumin/turmeric supplementation on blood pressure (BP). METHODS A systematic search was undertaken in Medline, Embase, Scopus, ISI Web of Science, Google Scholar and Cochrane library up to May 2019 to identify randomized clinical trials assessing the effect of curcumin/turmeric on systolic BP (SBP) and diastolic BP (DBP). A random-effects model was used to analyze the impact of combined trials. Cochrane Risk of Bias Tool was applied to assess potential risks of bias. RESULTS A total of 11 studies comprising 734 participants were eligible and included in the meta-analysis to estimate pooled effect size. Results of the meta-analysis did not indicate any significant effect of curcumin/turmeric on SBP (-0.69 mmHg; 95% CI: -2.01, 0.64; I2 = 18%) and DBP (0.28 mmHg; 95% CI: -1.12, 1.68; I2 = 53%). However, subgroup analysis revealed a significant reduction only in SBP levels (-1.24 mmHg; 95% CI: -2.26, -0.22; I2 = 0%) but not DBP (0.29 mmHg; 95% CI: -0.65, 1.22; I2 = 1%) in studies with ≥12-week supplementation. No favorable effect of curcumin administration on SBP or DBP levels was found after stratification according to either participant's condition or type of intervention (turmeric, crude curcumin and high-absorption curcumin). CONCLUSION The present meta-analysis suggests that consuming curcumin/turmeric may improve SBP when administered in long durations. However, more studies are needed to confirm these results.

Abstract
BACKGROUND Diabetes mellitus and metabolic disorders are a major burden on the healthcare system. Irisin is a novel myokine reported to have beneficial effects on glucose and lipid metabolism. Vitamin D deficiency has been implicated in the development of diabetes and hold a critical role in diabetes-related complications. In the present study, we examined the efficacy of vitamin D supplementation on serum irisin levels, skeletal muscle irisin levels, and the expression of the irisin precursor, FNDC5 (fibronectin-type III domain-containing 5) in type I diabetes mellitus rats. METHODS Thirty-six adult male Sprague-Dawley rats (150 - 250 g) were randomly divided into four groups: group I: healthy control rats with no treatment (n=8), group II: healthy control rats receiving sesame oil as a placebo (n=8), group III: diabetic rats receiving sesame oil as placebo (n=10), group IV: diabetic rats treated with 4300 IU/kg/week vitamin D (n=10). Diabetes was induced by intraperitoneal (IP) injection of streptozotocin. At the end of the vitamin D intervention blood and triceps muscle samples were collected. RNA was extracted from muscle and real-time PCR was performed to examine FNDC5 gene expression. RESULTS Our study showed that the administration of vitamin D (4300 IU/kg/week) in a streptozotocin-diabetic rat model resulted in increased serum vitamin D levels, FNDC5 gene expression and muscle irisin levels. However, the levels of serum irisin were not significantly changed by the administration of vitamin D. CONCLUSION In conclusion, we show that vitamin D supplementation enhances serum vitamin D levels, FDNC5 gene expression and muscle irisin levels in the streptozotocin-diabetic rat model. Our study highlights the potential therapeutic effect of vitamin D supplementation for diabetes mellitus.

Abstract
OBJECTIVE Our objective was to perform a systematic review and meta-analysis on randomized controlled trials (RCTs) assessing the effect of curcumin on serum adiponectin concentration. METHODS We searched PubMed/Medline, Scopus, ISI Web of Science, Cochrane Library, and Google scholar databases up to April 2019. RCTs conducted among human adults studied the effects of curcumin on serum adiponectin concentrations as an outcome variable was included. The weighted mean differences (WMD) and standard deviations (SD) of change in serum adiponectin levels were calculated. The random effects model was used for deriving a summary of mean estimates with their corresponding SDs. RESULTS Out of 313 records, 6 trials that enrolled 652 subjects were included. The pooled results showed that curcumin supplementation significantly increased adiponectin concentrations in comparison with placebo (WMD: 0.82 Hedges' g; 95% confidence interval (CI): 0.33 to 1.30, P˂0.001). Greater effects on adiponectin were observed in trials lasting ≤10 weeks (WMD: 1.05 Hedges' g; 95% CI: 0.64 to 1.45, P˂0.001). CONCLUSION Curcumin significantly improves adiponectin concentrations. However, due to some limitations in this study, further studies are needed to reach a definitive conclusion about the effect of curcumin on the levels of adiponectin.

Abstract
Pemphigus vulgaris (PV) is a severe, bullous, autoimmune disease of the skin and mucous membranes. Corticosteroids are usually the main core treatment for controlling PV, which could lead to several side effects such as insulin resistance, osteoporosis, and cardiovascular disorders. The aim of this study is to evaluate the protective effects of l-carnitine (LC) supplementation in PV patients under corticosteroid treatment. In this randomized, double-blind, placebo-controlled clinical trial, 48 patients with PV were divided randomly into two groups to receive 2 g LC (n = 24) or a placebo (n = 24) for 8 weeks, respectively. Serum levels of osteopontin (OPN), bone morphogenic protein 4 (BMP4), cystatin C, systolic and diastolic blood pressure, 25 hydroxyvitamin D3, and LC were evaluated at the beginning and at the end of the study. LC supplementation demonstrated a significant increase in serum carnitine (p < .001). In addition, at the end of the trial, LC supplementation significantly decreased serum BMP4 (p = .003), OPN (p = .03), and cystatin C (p = .001) levels. There was no significant effect on blood pressure in comparison with the placebo. During study, no harmful side effects were reported by patients. These findings indicate that LC supplementation significantly leads to favorable changes in OPN, BMP4, and cystatin C in PV patients under corticosteroid therapy. However, further investigations are required to confirm these results.

Abstract
BACKGROUND AND AIMS Policosanol contains a mixture of concentrated primary aliphatic alcohols extracted from sugar cane wax and is recognized as a cholesterol-lowering drug but previous studies reported that it could be helpful for reducing blood pressure as well. We aimed to systematically review all randomized control trials (RCTs) evaluating the efficacy of policosanol supplementation for lowering high blood pressure. METHODS AND RESULTS The following databases were searched up to March 2019: PubMed, Scopus, ISI Web of Science and the Cochrane library. Eligible RCTs were included if they investigate the effects of policosanol supplementation on systolic (SBP) and diastolic (DBP) blood pressure. Pooled effect size was measured using random effect model (DerSimmonon method). A total of nineteen studies with twenty-four arms were considered. Pooled effect size showed that SBP (WMD: -3.423 mmHg, 95% CI: -5.315, -1.531; p < 0.001) and DBP (WMD: -1.468 mmHg 95% CI: -2.632, -0.304, p = 0.013). decrease significantly after policosanol supplementation with significant heterogeneity among included studies (I2 = 78.5% and 78.9% for SBP and DBP respectively). All subgroups showed a significant effect of policosanol supplementation except patients with mixed dyslipidemia for SBP and DBP and overweight subjects for DBP. CONCLUSION Policosanol could lower SBP and DBP significantly; future long term studies are required to confirm these findings in the general population.
