Abstract
BACKGROUND Diabetic nephropathy (DN) is a common complication of type 2 diabetes. Okra (Abelmoschus esculentus L) is reported to have anti-diabetic effects. The present study aimed to investigate the effects of dried okra extract (DOE) supplementation on lipid profile, renal function indices, and expression of inflammatory genes, as well as serum level of soluble Receptor for Advanced glycation end products (sRAGE) in patients with DN. METHODS In this triple-blind randomized placebo-controlled clinical trial, 64 eligible patients with DN received either 125 mg of DOE or placebo daily along with DN-related nutritional recommendations for 10 weeks. Changes in kidney indices including proteinuria and estimated glomerular filtration rate (eGFR), lipid profile, serum SRAGE, as well as the expression of RAGE, ICAM-1, and IL-1 genes were measured over 10 weeks. RESULTS After adjustment for the potential confounders, between-group analyses showed no significant differences in terms of lipid profile, kidney function indices, sRAGE, and RAGE-related inflammatory genes expression after 10 weeks. CONCLUSION Daily 125 mg DOE along with nutritional recommendations on top of usual care did not lead to significant changes in renal function indices, lipid profile, and inflammatory genes expression in patients with DN.

Abstract
The present study was carried out to evaluate the effects of okra extract supplementation on kidney function, glycaemic control, inflammation and gene expression in patients with diabetic nephropathy (DN). A total of sixty-four DN patients based on the inclusion and exclusion criteria were recruited in this triple-blind placebo-controlled randomised clinical trial. Participants were randomly allocated to receive a 125-mg capsule of dried okra extract (DOE) (n 32) or placebo (n 32) for 10 weeks. At the baseline and endpoint of the trial, kidney function, glycaemic indices, inflammation and gene expression were evaluated. Statistical analysis showed that fasting blood glucose, HbA1c and insulin resistance significantly reduced in the DOE group although between-group analysis did not show any significant difference. Also, no significant difference was observed in urine protein, urine creatinine and high-sensitivity C-reactive protein between the two groups. Furthermore, gene expression of PPAR-α, PPAR-γ, transforming growth factor-beta and Nrf-2 did not affect the end of the trial in comparison with the baseline. According to the present study, DOE did not have impressive effects on kidney function, inflammation, glycaemic management and gene expression in patients with DN.

Abstract
Increasing evidence suggests that organic vanadium compounds are bioavailable and safe therapeutic agents with insulin-mimetic and insulin-enhancing features. The objective of the current study was to examine the effect of vanadium-enriched yeast (VEY) supplementation on the gene expression level of insulin receptor substrates and clinical manifestations of obese type 2 diabetic mellitus (T2DM) patients. In this randomized, double-blind, placebo-controlled clinical trial, 44 obese T2DM patients were randomly allocated into either VEY (0.9 mg/day vanadium pentoxide) or placebo group for 12 weeks. The mRNA expression level of protein tyrosine phosphatase 1B (PTP1B), phosphatase and tensin homolog (PTEN), mitogen-activated protein kinase (MAPK), ribosomal protein S6 kinase (S6K), and nuclear factor kappa-light-chain-enhancer of activated B cells (NFƘB) genes in the peripheral blood mononuclear cells, serum levels of metabolic parameters, anthropometric indices, as well as the quality of life, and dietary intake were collected at pre- and post-intervention phases. Analysis of covariance was performed to obtain the corresponding effect size. Results showed that VEY administration significantly decreased anthropometric indices and glycemic parameters and increased insulin sensitivity after adjusting for potential covariates (p < 0.05), in comparison to the placebo group. Additionally, VEY supplementation was significantly effective on MAPK, PTP1B, and NFƘB gene expression level, compared to the placebo group. No significant changes were noticed for dietary intake, quality of life, and lipid profile in the VEY group, compared to the placebo group. Overall, VEY supplementation can be considered as a promising safe adjunct therapy for improving anthropometric indices and glycemic parameters in T2DM patients.

Abstract
BACKGROUND Obesity is a multifaceted disease characterized by an abnormal accumulation of adipose tissue. Growing evidence has proposed microbiota-derived metabolites as a potential factor in the pathophysiology of obesity and related metabolic conditions over the last decade. As one of the essential metabolites, butyrate affects several host cellular mechanisms related to appetite sensations and weight control. However, the effects of butyrate on obesity in humans have yet to be studied. Thus, the present study was aimed to evaluate the effects of sodium butyrate (SB) supplementation on the expression levels of peroxisome proliferator activated-receptor (PPAR) gamma coactivator-1α (PGC-1α), PPARα and uncoupling protein 1 (UCP1) genes, serum level of glucagon-like peptide (GLP1), and metabolic parameters, as well as anthropometric indices in obese individuals on a weight loss diet. METHODS This triple-blind randomized controlled trial (RCT) will include 50 eligible obese subjects aged between 18 and 60 years. Participants will be randomly assigned into two groups: 8 weeks of SB (600 mg/day) + hypo-caloric diet or placebo (600 mg/day) + hypo-caloric diet. At weeks 0 and 8, distinct objectives will be pursued: (1) PGC-1α, PPARα, and UCP1 genes expression will be evaluated by real-time polymerase chain reaction; (2) biochemical parameters will be assayed using enzymatic methods; and (3) insulin and GLP1 serum level will be assessed by enzyme-linked immunosorbent assay kit. DISCUSSION New evidence from this trial may help fill the knowledge gap in this realm and facilitate multi-center clinical trials with a substantially larger sample size.

Abstract
Background: Diabetes is a risk factor for chronic kidney disease because it induces nephropathy. Okra is a rich source of antioxidants, vitamins, minerals, and fibers, of which favorable effects in diabetes have been reported in many animal studies. The present trial aimed to investigate the effect of dried okra extract (DOE) supplementation on anthropometric measures, body composition, appetite, and dietary intake in diabetic nephropathy (DN) patients. Methods: In this triple-blind placebo-controlled randomized clinical trial, 64 DN patients were randomly allocated to receive a 125-mg capsule of DOE (n=32) or placebo (n=32) for 10 weeks. At baseline and endpoint of the trial, anthropometric variables, body composition indices, dietary intake, and appetite scores were evaluated. Results: The results showed that energy (P=0.047, CI: -425.87, -3.25, ES: 0.539) and carbohydrate (P=0.038, CI: -85.64, -2.53, ES: 0.555) intake as well as desire to eat salty food (P=0.023) were reduced in DOE group at the endpoint, compared to the baseline values. However, anthropometric measures, body composition, and appetite score were not significantly different between the two study groups. Conclusion: In conclusion, the present clinical trial showed that DOE could significantly decrease energy intake and carbohydrate consumption in the DN patients. Further clinical trials are needed to determine the effects of this supplement.

Abstract
Background: Oxidative stress has a significant role in the commencement and development of hyperglycemia. Vanadium, as a transitional metal with redox properties, enters the redox process, produces free radicals, and distracts the pro-antioxidant balance. The present animal systematic review aimed to assess the effect of vanadium supplementation on inflammation and oxidative stress biomarkers in diabetes-induced animals. Methods: A systematic search was conducted using the PubMed, Scopus, and web of science databases from 1990 to 2021, according to the inclusion and exclusion criteria. The search strategy was based on the guidelines for systematic review of animal experiments and Preferred Reporting Items for Systematic Reviews (PRISMA). Criteria for eligibility were animal-based studies, evaluating the therapeutic effects of vanadium on inflammatory and oxidative stress biomarkers in diabetes. The Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) tool was used for assessing the methodological quality of included studies. Results: In the present study, 341 articles were evaluated out of which 42 studies were eligible for inclusion. The majority of the studies confirmed the advantageous properties of vanadium on inflammatory and oxidative stress biomarkers. A minor risk of bias was reported, based on the SYRCLE's tool. Conclusion: According to the findings, well-designed clinical trials are warranted to assess the long-lasting effects of various vanadium compounds on inflammatory and oxidative stress biomarkers.

Abstract
BACKGROUND Diabetic dyslipidemia is caused by hyperglycemia and excessive mobilization of storage lipids, leading to increasing concentrations of triglycerides and total cholesterol. Due to the insulin-mimetic or insulin-enhancer features of vanadium, it has been recognized as a regulator of cell metabolism with hypoglycemic and hypolipidemic properties. The purpose of the current animal systematic review was to evaluate the effect of vanadium administration on diabetic dyslipidemia in diabetic animals. METHODS This is, to our knowledge, the first systematic review with the aim of investigating the relationship between vanadium and diabetic dyslipidemia among diabetes induced animals. Searches were performed in PubMed, Scopus, and web of science databases for animal studies examining the effect of vanadium on diabetic dyslipidemia in diabetic animals. RESULTS Of 124 full-text articles assessed, 48 animal studies were included in the present study with minor risk of bias. The majority of the studies confirmed the beneficial effects of different vanadium compounds in at least one of the parameters of lipid profile, especially regarding triglyceride and total cholesterol. CONCLUSION Current findings lend support to assess the long-term effects of different forms and doses of vanadium on lipid profile through well-designed clinical trials.

Abstract
Background: There is a well-documented cross-talk between the gut and brain. Evidence is accumulating to suggest beneficial effects of psychobiotics [prebiotics, probiotics or synbiotics] on psychological distress in disease states. However, their role in healthy status remains relatively unclear. Objectives: The present study was aimed to clarify if psychobiotics could influence behavioral responses and physiological stress in healthy rats. Methods: In the present experiment, 28 male Wistar rats were divided into four groups (healthy rats treated by Lactobacillus plantarum (L.plantarum), inulin and their combination (synbiotic) and control group). Then, psychobiotics were administered to the intervention groups for 8 weeks. Behavioral tests (Morris water maze, Elevated plus maze, and Forced swimming test) were performed at the endpoint. Then, serum and brain levels of superoxide dismutase, malondialdehyde, glutathione peroxidase, total antioxidant capacity, brain-derived neurotrophic factor (BDNF), and serotonin were measured. Results: Our finding indicated that unlike inulin, the administration of L.plantarum and synbiotic could ameliorate depression and anxiety-like behavior and cognitive performance (P<0.05). Serum and brain oxidative stress markers were significantly improved by synbiotic consumption. Intake of L.plantarum led to decreased oxidative stress in the hippocampus and amygdala (P<0.05). Moreover, a significant increase in hippocampal serotonin and BDNF concentration was observed after synbiotic and L.plantarum intake (P<0.05). In addition, there was a strong correlation of serum and brain markers with behavioral performance (P< 0.05). Conclusion: Our study suggests that psychobiotics therapy may have favorable effects on the amelioration of psychological disorders.

Abstract
Objectives According to the recent epidemiological studies, patients with diabetes mellitus (DM) may be at higher risk of hospitalization due to COVID-19. Regarding the important role of nutrition on the immunity, the present review article aimed to outline nutritional support of DM during the outbreak of COVID-19 with a mechanistic insight. Methods Searches were performed in PubMed/MEDLINE, ScienceDirect, Scopus, and Google Scholar databases from 2000 until December 2020 using the following keywords. All relevant clinical and experimental studies published in English were included. Results Evidences revealed that hyperglycemia is a significant predictor of some viral infections including COVID-19 which can exacerbate the complications of DM. According to the literature review, adequate intake of dietary protein, fiber, essential fatty acids and some micronutrients especially vitamins D, C, B12, folate, zinc and selenium has beneficial effects on the prevention and treatment of COVID-19 in diabetic patients through modulation of innate and adaptive immune responses or direct effects on virus enzymes or the rate of cell entrance. Conclusions It is well understood that malnutrition may increase susceptibility to viral infections and disease progression. Therefore, considering nutritional status of diabetic patients and reasonable supplementation of the above mentioned nutrients can ameliorate the symptoms of COVID-19 in DM. However, further well-designed clinical trials are needed to determine their therapeutic dose.

Abstract
Background: The novel coronavirus (COVID-19) is considered as the most life-threatening pandemic disease during the last decade. The individual nutritional status, though usually ignored in the management of COVID-19, plays a critical role in the immune function and pathogenesis of infection. Accordingly, the present review article aimed to report the effects of nutrients and nutraceuticals on respiratory viral infections including COVID-19, with a focus on their mechanisms of action. Methods: Studies were identified via systematic searches of the databases including PubMed/ MEDLINE, ScienceDirect, Scopus, and Google Scholar from 2000 until April 2020, using keywords. All relevant clinical and experimental studies published in English were included. Results: Protein-energy malnutrition (PEM) is common in severe respiratory infections and should be considered in the management of COVID-19 patients. On the other hand, obesity can be accompanied by decreasing the host immunity. Therefore, increasing physical activity at home and a slight caloric restriction with adequate intake of micronutrients and nutraceuticals are simple aids to boost host immunity and decrease the clinical manifestations of COVID-19. Conclusion: The most important nutrients which can be considered for COVID-19 management are vitamin D, vitamin C, vitamin A, folate, zinc, and probiotics. Their adequacy should be provided through dietary intake or appropriate supplementation. Moreover, adequate intake of some other dietary agents including vitamin E, magnesium, selenium, alpha linolenic acid and phytochemicals are required to maintain the host immunity.

Abstract
Inflammation is considered a key mechanism leading to obesity. Dietary patterns and certain food items influence inflammation. Few studies have investigated the contribution of major dietary patterns to biological measures of inflammation. Therefore, the present study aimed to examine the associations of different dietary patterns with dietary inflammatory index (DII), systemic inflammation, and insulin resistance (IR) in the apparently healthy obese. In this cross-sectional study, 151 abdominally obese subjects were recruited from the Northwest of Iran. Dietary intake, demographic data, anthropometric indices, and physical activity (PA) was assessed. DII scores were calculated based on a validated 168-item food frequency questionnaire (FFQ). Three dietary patterns were identified, using principal component analysis. Basal blood samples were collected to determine biochemical parameters. Linear regression test with adjusted beta estimates was applied for data analysis. Three dietary patterns were extracted as Healthy, Western, and Traditional. Body mass index (BMI) (p < 0.01) and fat mass (p < 0.001) were directly associated with the Western dietary pattern. Conversely, serum lipopolysaccharide-binding protein (LBP) (b = - 0.1, p < 0.04) was negatively associated with Healthy dietary pattern, after controlling for confounders. The Traditional pattern was found to be inversely related to DII (b = - 0.3, p < 0.001). The association was also reveresed between Traditional pattern and IR (Odds Ratio: 0.3 (95% Confidence Interval 0.1-0.9)). The results suggested that the Western dietary pattern was related to higher BMI and fat mass. In addition, the Healthy pattern was associated with decreased levels of LBP. Adherence to the Traditional dietary pattern was inversely related to DII as well as IR.

Abstract
This case-control study aimed to assess the relationship between food insecurity, its related risk factors and NAFLD among 210 subjects. The demographic and socioeconomic characteristics, anthropometric indices, and food insecurity and depression status were assessed. The prevalence of food insecurity was 56.8% and 26.1% in cases and controls (p < .001), respectively. The chance of NAFLD in the food insecure, depressed, overweight, and obese subjects was 2.2 (95%CI: 1.12-3.43), 1.9 (95%CI: 1.02-3.62), 2.6 (95%CI: 1.81-3.92), and 2.9 (95%CI: 2.02-5.34) times higher than food secured, normal, and normal weight subjects, respectively. A higher waist circumference (men, OR = 2.9, p < .001; women, OR = 2.6, p < .001), a high waist-to-hip ratio (men, OR = 2.3, p < .001; women, OR = 2.7, p < .001), an increased waist-to-height ratio (OR = 2.9, p < .001), and a higher body fat percentage (men, OR = 3.0, p < .001; women, OR = 3.3, p < .001) were associated with an increased risk of NAFLD. The odds of NAFLD increased by increment in serum triglyceride (TG) levels (OR = 2.6, p < .001) and decreased by increase in serum high-density lipoprotein cholesterol (HDL-C) (OR = 0.34, p < .001). Compared to controls, patients with NAFLD were more likely to have higher TG/HDL-C ratio (OR = 3.3, p < .001). It seems food insecurity was an important risk factor for NAFLD. Additionally, some indicators of dyslipidemia significantly increased the risk of NAFLD.

Abstract
BACKGROUND This study aimed to investigate the association between dietary patterns and non-alcoholic fatty liver disease (NAFLD) among Iranian adults. METHODS This case-control study was conducted on 210 subjects. NAFLD diagnosis was made by ultrasound examination. Anthropometric measures, physical activity, fasting serum levels of glucose, alanine aminotransferase (ALT), aspartate aminotransferase, and lipid profile were assessed. A three-day food diary was used to assess dietary intakes of the subjects. Dietary patterns were determined using factor analysis. To determine the relationship between dietary patterns and NAFLD, multivariable-adjusted odds ratio (OR) obtained from the logistic regression analysis was used. RESULTS Two dietary patterns were extracted as follows: vegetables, legumes, fruits, and low-fat dairy products (VLFD) ; and sweet, hydrogenated fat, red and processed meat, and soft drink (SHMS) dietary patterns. By taking all possible confounders into account, the VLFD dietary pattern was found to be significantly related to lower odds of NAFLD, while the SHMS dietary pattern was independently related to higher odds of NAFLD (P < 0.05). Among major food groups, high consumption of processed meat, hydrogenated fats, sweets and desserts, and soft drinks was positively related to NAFLD (P < 0.05), whereas vegetable consumption exhibited a protective role against NAFLD (P = 0.01). CONCLUSION The VLFD dietary pattern was associated with reduced likelihood of having NAFLD, while the SHMS dietary pattern was associated with higher likelihood. Therefore, the VLFD dietary pattern might be useful in the nutritional strategies for NAFLD patients. Further studies with larger sample sizes and prospective design are warranted.

Abstract
Background: Non-alcoholic fatty liver disease (NAFLD) is the most frequent cause of chronic liver disease in the world. The current interventional trial aimed to evaluate the effects of supplementation with oleoylethanolamide (OEA) in combination with weight loss intervention on some atherogenic indices as well as hematological parameters in patients newly diagnosed with NAFLD. Methods: In this triple-blinded, randomized, placebo-controlled clinical trial, 76 obese patients with NAFLD confirmed by ultra-sonographic findings were randomly assigned to receive a weight reduction diet plus either 250 mg OEA (n=38) or placebo (n=38) for 12 weeks. Atherogenic factors including total cholesterol/high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C)/HDL-C, triglyceride (TG)/HDL-C, non-HDL-C/HDL-C ratios and non-HDL-C level, as well as hematological parameters were assessed before and after intervention. Results : After adjustment for potential confounding factors, between group analyses demonstrated a significantly lower LDL-C/HDL-C, TG/HDL-C, and non-HDL-C/HDL-C ratios in the OEA group compared to the placebo, post-intervention (95% confidence interval [CI]:0.06 to 0.85, P = 0.024; 95% CI: -2.06 to -0.05, P = 0.039; 95% CI: -1.05 to -0.02, P = 0.042,respectively). Additionally, OEA supplementation could significantly decrease the levels of red blood cell distribution width (RDW) compared to the placebo at the endpoint after considering potential confounding variables (95% CI: -0.56 to -0.003, P = 0.041). No significant differences were found between the two study groups in terms of other hematological parameters. Conclusion: The results of the current study indicated that OEA supplementation had beneficial effects on LDL-C/HDL-C, TG/HDL-C, and non-HDL-C/HDL-C ratios as well as RDW in obese patients with NAFLD.

Abstract
Nowadays, much attention has been paid to the link between gut microbiota and brain. The beneficial metabolic effects of probiotics and prebiotics in several diseases such as diabetes and obesity have been reported. However, studies bridging the association of gut microbiome with brain function in healthy states are rare. Therefore, it was hypothesized that the administration of Lactobacillus plantarum (L plantarum) and inulin may affect serum and hypothalamic metabolic parameters as well as oxidative markers in healthy male rats. Daily L plantarum (107 CFU/mL) and inulin (5% of daily food weight) or their combination (synbiotic) was given to healthy rats. Then, serum and hypothalamic levels of leptin, insulin, and oxidative markers were measured. Administration of synbiotic for 8 weeks led to significant changes in serum levels of high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, low-density lipoprotein/high-density lipoprotein ratio, triglyceride, and total cholesterol. The intake of synbiotic also resulted in a significantly reduced hypothalamic level of malondialdehyde and increased hypothalamic superoxide dismutase (SOD). Also, L plantarum could significantly increase hypothalamic SOD level. Furthermore, synbiotic administration insignificantly increased the hypothalamic and serum levels of insulin and leptin. These findings suggest that the synbiotic could significantly improve oxidative markers and lipid profile in healthy rats. Therefore, simultaneous intake of L plantarum and inulin appears to be more effective in the amelioration of metabolic and oxidative parameters.

Abstract
Obesity is associated with an increased risk of several major noncommunicable diseases, and is an important public health concern globally. Dietary fat content is a major contributor to the increase in global obesity rates. Changes in dietary habits, such as the quality of fatty acids in the diet, are proposed to prevent obesity and its metabolic complications. In recent years, a number of studies have found that oleic acid (OA), the most common MUFA in daily nutrition, has protective effects against human disease. Importantly, there is emerging evidence indicating the beneficial effects of OA in regulating body weight. Accordingly, the objective of this systematic review was to investigate the effects of diets enriched in monounsaturated OA on the management and prevention of obesity, emphasizing possible mechanisms of action of OA in energy homeostasis. Searches were performed in PubMed/MEDLINE, ScienceDirect, Scopus, ProQuest, and Google Scholar databases for clinical trials that examined the effects of diets rich in OA on obesity. Of 821 full-text articles assessed, 28 clinical trials were included in the present study. According to the studies examined in this review, diets enriched in OA can influence fat balance, body weight, and possibly energy expenditure. Importantly, abdominal fat and central obesity can be reduced following consumption of high-OA-containing meals. Mechanistically, OA-rich diets can be involved in the regulation of food intake, body mass, and energy expenditure by stimulating AMP-activated protein kinase signaling. Other proposed mechanisms include the prevention of the nucleotide-binding oligomerization domain-like receptor 3/caspase-1 inflammasome pathway, the induction of oleoylethanolamide synthesis, and possibly the downregulation of stearoyl-CoA desaturase 1 activity. In summary, current findings lend support to advice not restricting consumption of OA-rich meals so as to maintain a healthy body weight.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common noncommunicable diseases worldwide. The present study aimed to investigate the effects of oleoylethanolamide (OEA) supplementation combined with calorie restriction on inflammation, body composition, and hepatic fibrosis among obese patients with NAFLD. In this 12-week randomized clinical trial, 76 obese patients newly diagnosed with NAFLD were randomly allocated into either OEA or placebo group. The weight-loss diet was also designed for both groups. Pre- and postintervention messenger RNA expression levels of the transcription factor nuclear factor-κB (NF-κB), interleukin-6 (IL-6) and IL-10, body composition, and NAFLD fibrosis score were assessed. At the end of the study, the OEA group showed lower NF-κB and IL-6 expression levels compared to the placebo (p < .01). However, IL-10 expression level was approximately twofold higher in the OEA group compared to the placebo group (p = .008). A significant reduction was observed in the fat mass of the OEA group compared to the placebo (p = .044) postintervention. In addition, OEA supplementation led to a significant increase in fat-free mass in the OEA group compared to the placebo (p = .032). A remarkable increase was observed in resting metabolic rate (RMR) in the OEA group (p = .009); however, it was not found in the placebo group. There were no significant between-group differences in RMR postintervention. In addition, no significant within-and between-group differences were observed in the NAFLD fibrosis score at the end of the trial. Treatment with OEA along with weight-loss intervention could significantly improve inflammation and body composition in patients with NAFLD.

Abstract
BACKGROUND & AIMS Type 2 diabetes mellitus, as a metabolic disorder, can lead to diabetic cardiomyopathy, identified by cardiomyocyte apoptosis and myocardial fibrosis. Brain-derived neurotrophic factor (BDNF) and serotonin are two neurotransmitters that can control cardiomyocyte apoptosis and myocardial fibrosis through their cardiac receptors. In the present study, we investigated the impacts of L. plantarum and inulin supplementation on the inhibition of cardiac apoptosis and fibrosis by modulating intestinal, serum, and cardiac levels of serotonin and BDNF as well as their cardiac receptors. METHODS Diabetes was induced by a high-fat diet and streptozotocin in male Wistar rats. Rats were divided into six groups and were supplemented with L. plantarum, inulin or their combination for 8 weeks. Finally, the rats were killed and levels of intestinal, serum, and cardiac parameters were evaluated. RESULTS Concurrent administration of L. plantarum and inulin caused a significant rise in the expression of cardiac serotonin and BDNF receptors (P < 0.001) as well as a significant fall in cardiac interstitial and perivascular fibrosis (P < 0.001, both) and apoptosis (P = 0.01). Moreover, there was a strong correlation of cardiac 5-Hydroxytryptamine 2B (5-HT2B) and tropomyosin receptor kinase B (TrkB) receptors with interstitial/perivascular fibrosis and apoptosis (P < 0.001, both). CONCLUSIONS/INTERPRETATION Results revealed beneficial effects of L. plantarum, inulin or their combination on intestinal, serum, and cardiac serotonin and BDNF accompanied by higher expression of their cardiac receptors and lower levels of cardiac apoptotic and fibrotic markers. It seems that L. plantarum and inulin supplementation could be considered as a novel adjunct therapy to reduce cardiac complications of type 2 diabetes mellitus.

Abstract
The effects of oleoylethanolamide (OEA) on NAFLD are yet to be examined in human. The objective of the present study was to examine the effects of OEA supplementation along with weight loss intervention on the expression of PPAR-α, uncoupling proteins 1and 2 (UCP1 and UCP2) genes in the peripheral blood mononuclear cells (PBMCs), metabolic parameters, and anthropometric indices among obese patients with NAFLD. In this triple-blind placebo-controlled randomized clinical trial, 76 obese patients newly diagnosed with NAFLD were randomly allocated into either OEA or placebo group along with calorie-restricted diets for 12 weeks. At pre-and post-intervention phase, mRNA expression levels of PPAR-α, UCP1, and UCP2 genes in the PBMCs, serum levels of metabolic parameters as well as diet and appetite sensations were assessed. There was a significant increase in the expression levels of PPAR-α, UCP1, and UCP2 genes in the PBMCs, compared to the placebo at the endpoint. A significant decrease in the anthropometric indices, energy and carbohydrate intakes, glycemic parameters, except for hemoglobin A1c concentration was also observed in the OEA group, compared to the placebo group. OEA treatment significantly resulted in decreased serum levels of triglyceride (TG), alanine aminotransferase (ALT), aspartate aminotransferase (AST), ALT/AST, increased serum levels of high-density lipoprotein cholesterol (HDL-C), and improved appetite sensations. Importantly, a significant improvement in TG, ALT, AST, ALT/AST, HDL-C levels as well as appetite sensations by OEA were under the influence of body mass index (BMI). Although liver steatosis severity was significantly reduced in both groups, the between-group differences did not reach statistical significance (P = 0.061). In conclusion, the present study, for the first time, revealed that OEA supplementation significantly improved anthropometric and metabolic risk factors related to NAFLD.

Abstract
BACKGROUND Overweight and obesity have become a significant public health concern in both developing and developed countries. Due to the health implications of weight-reduction behaviors, it is important to explore the factors that predict their occurrence. Therefore, the present study was performed to examine factors affecting the behavioral intention of weight management as well as assess the predictive power of the Health Belief Model (HBM) for body mass index (BMI). METHODS This cross-sectional study was conducted among 336 female students recruited from dormitories of Tabriz University of Medical Sciences, using quota sampling technique. Data were collected by a structured questionnaire in seven parts (including perceived severity, perceived susceptibility, perceived benefit, perceived barrier, cue to action, self-efficacy in dieting and physical activity, and behavioral intention of weight management), based on the HBM. Structural equation modeling (SEM) was conducted to identify the relationship between HBM constructs and behavioral intention of weight management. Linear regression model was performed to test the ability of the HBM to predict students' BMIs. RESULTS Higher level of perceived threats (sum of perceived susceptibility and severity) (β = 0.41, P<0.001), perceived benefits (β = 0.19, P = 0.009), self-efficacy in exercise (β = 0.17, P = 0.001), and self-efficacy in dieting (β = 0.16, P = 0.025) scales was significantly related to greater behavioral intention of weight management. Moreover, perceived threat mediated the relationships between perceived cue to action, perceived benefits, self-efficacy in exercise, and weight management practices. The fit indices of the SEM model seemed acceptable. The final regression model explained approximately 40% of variance in BMI (P<0.001). Additionally, perceived severity, barrier, and self-efficacy in dietary life were the significant variables to predict students' BMIs. CONCLUSIONS These findings suggest that health education programs based on the HBM needs to be integrated in preventive health programs and health interventions strategies to ensure adherence and well-being of the participants.

Abstract
Along with an increase in overweight and obesity among all age groups, the development of efficacious and safe anti-obesity strategies for patients, as well as health systems, is critical. Oleoylethanolamide (OEA), a high-affinity endogenous ligand of nuclear receptor peroxisome proliferator-activated receptor alpha (PPAR-α), plays important physiological and metabolic actions. OEA is derived from oleic acid, a monounsaturated fatty acid, which has beneficial effects on body composition and regional fat distribution. The role of OEA in the modulation of food consumption and weight management makes it an attractive molecule requiring further exploration in obesogenic environments. This systematic review was conducted to assess the effects of OEA on the obesity management, with emphasizing on its physiological roles and possible mechanisms of action in energy homeostasis. We searched PubMed/Medline, Google Scholar, ScienceDirect, Scopus, ProQuest, and EMBASE up until September 2019. Out of 712 records screened, 30 articles met the study criteria. The evidence reviewed here indicates that OEA, an endocannabinoid-like compound, leads to satiation or meal termination through PPAR-α activation and fatty acid translocase (FAT)/CD36. Additionally, the lipid-amide OEA stimulates fatty acid uptake, lipolysis, and beta-oxidation, and also promotes food intake control. OEA also exerts satiety-inducing effects by activating the hedonic dopamine pathways and increasing homeostatic oxytocin and brain histamine. In conclusion, OEA may be a key component of the physiological system involved in the regulation of dietary fat consumption and energy homeostasis; therefore, it is suggested as a possible therapeutic agent for the management of obesity.

Abstract
Background The manipulation of gut microbiota as a target has been suggested to reduce the risks for a number of diseases such as type 2 diabetes mellitus (T2DM). Conversely, T2DM is associated with complications such as gut and brain disorders. Furthermore, the impact of probiotics and prebiotics to improve T2DM complications are reported. Thus, the present study seeks to investigate the therapeutic and neuropsychological effects of L. plantarum and inulin in diabetic rats. Methods Throughout the investigation, L. plantarum, inulin or their combination (synbiotic) was administered to diabetic rats. in the end, fecal samples were collected to evaluate the gut microbial composition. Then behavioral tests were conducted. Subsequently, the obtainment of the prefrontal cortex (PFC) and hippocampal samples. Results Our data demonstrated that administration of L. plantarum and inulin could improve gut dysbiosis and oxidative stress status. In addition, it could ameliorate serotonin and BDNF/TrkB signaling pathway. Notably, a strong correlation between the gut microbiota changes and cognition responses was observed. Interestingly, synbiotics intake exploited a rather powerful effect on oxidative stress markers. Conclusion The findings confirm that there is a beneficial therapeutic potential of supplements, especially symbiotic. Moreover, neuropsychological improvement associated with balanced gut microbiome.

Abstract
BACKGROUND It is well established that diminished reproductive health is one of the notable long-term outcomes of type 2 diabetes mellitus (T2DM), especially among males. Due to the global increasing rate of T2DM and infertility, we aimed to investigate the impact of Lactobacillus plantarum (L. plantarum), inulin, and their combinatory supplementation on fertility markers as well as testicular kisspeptin and androgen receptor (AR)'s expression in diabetic male rats. METHODS Thirty-five Male Wistar rats with Streptozotocin-induced T2DM were supplemented with L. plantarum, inulin, or their combination for 8 weeks. At the end-point, the animals were sacrificed and serum, testicular, and seminal parameters were studied. RESULTS Administration of L. plantarum and inulin in diabetic male rats improved sperm motility and viability (P < 0.001, both) as well as testicular tissue development via increasing leydig cell number, testicular spermatid count, and diameter of seminiferous tubules (P < 0.001, all). Testicular expression of Kisspeptin was elevated by inulin supplementation (P = 0.01). L. plantarum administration increased testicular AR expression (P = 0.01). The expression of Kisspeptin showed a remarkable correlation with fertility markers (P < 0.001). CONCLUSION Supplementation with either L. plantarum, inulin, or their combination can prevent infertility caused by T2DM in male rats via improving testicular kisspeptin and AR expression, leydig cell count, and effectively increasing epididymal sperm motility and viability.

Abstract
BACKGROUND T2DM may cause increased levels of oxidative stress and cardiac apoptosis through elevated blood glucose. The present study investigated the effects of Lactobacillus plantarum (L. plantarum) as a probiotic strain and inulin as a prebiotic supplement on cardiac oxidative stress and apoptotic markers in type 2 diabetes mellitus (T2DM) rats. METHODS A high-fat diet and a low dose of streptozotocin were used to induce type 2 diabetes. The rats were divided into six groups which were supplemented with L. plantarum, inulin, or their combination for 8 weeks. RESULTS The results showed improved activity of cardiac antioxidant parameters including total antioxidant capacity (TAC), superoxide dismutase (SOD), and glutathione peroxidase (GPx) (P < 0.001, P < 0.01, and P < 0.01, respectively) and decreased level of cardiac malondialdehyde (MDA) concentration (P < 0.05). These changes were accompanied with increased protein expression of cardiac obesity receptor (Ob-R) (P = 0.05) and reduced apoptotic markers such as tumor necrosis factor-alpha (TNF-α), Fas ligand (FasL), and caspase proteins (P < 0.001, P = 0.003, and P < 0.01, respectively) in T2DM rats after concurrent L. plantarum and inulin supplementation. Moreover, a remarkable correlation of cardiac Ob-R and oxidative stress parameters with cardiac apoptotic markers was observed (P < 0.01). CONCLUSION The concurrent use of L. plantarum and inulin seems to be beneficial, as they can lead to decreased heart complications of T2DM via reducing cardiac apoptotic markers.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease. Recently, some novel compounds have been investigated for the prevention and treatment of NAFLD. Oleoylethanolamide (OEA), an endogenous PPAR-α agonist, has exhibited a plethora of pharmacological properties for the treatment of obesity and other obesity-associated metabolic complications. This systematic review was performed with a focus on the effects of OEA on the risk factors for NAFLD. PubMed, Scopus, Embase, ProQuest, and Google Scholar databases were searched up to December 2018 using relevant keywords. All articles written in English evaluating the effects of OEA on the risk factors for NAFLD were eligible for the review. The evidence reviewed in this article illustrates that OEA regulates multiple biological processes associated with NAFLD, including lipid metabolism, inflammation, oxidative stress, and energy homeostasis through different mechanisms. In summary, many beneficial effects of OEA have led to the understanding that OEA may be an effective therapeutic strategy for the management of NAFLD. Although a wide range of studies have demonstrated the most useful effects of OEA on NAFLD and the associated risk factors, further clinical trials, from both in vivo studies and in vitro experiments, are warranted to verify these outcomes.

Abstract
OBJECTIVE Low-grade inflammation is a characteristic of various conditions, including obesity. Diet is regarded as a strong modifier of inflammation. The potential links between inflammatory properties of diet and adipokines as well as insulin resistance (IR) warrant further investigation. Therefore, this study aimed to examine the associations of the dietary inflammatory index (DII) with serum chemerin, omentin, and lipopolysaccharide-binding protein (LBP) as well as IR among apparently healthy obese adults. DESIGN In this cross-sectional study, 171 abdominally obese subjects were recruited in the northwest of Iran. Demographic data, dietary intake, anthropometric indices, and physical activity (PA) were assessed. DII scores were calculated based on dietary intake, using a validated 168-item food frequency questionnaire (FFQ). Basal blood samples were collected to determine the biochemical parameters. A linear regression test with adjusted beta estimates was applied for data analysis. RESULT Compared to those with higher DII score, the group with lower DII score (anti-inflammatory diet) had higher protein (83.62 ± 36.42 g vs. 71.61 ± 25.94 g) and lower carbohydrate (325.00 ± 125.76 g vs. 378.19 ± 137.69 g) intake. Participants with higher DII score had lower consumption of polyunsaturated and monounsaturated fats as well as fiber and higher saturated fats (p < .001). Those with elevated DII score had higher levels of chemerin (p = .034) and LBP (p = .040), compared to those with lower DII. Omentin showed no significant differences between groups with different DII scores. Additionally, people with a more proinflammatory diet had higher FBS (p = .005); however, other markers of IR did not differ by DII scores. CONCLUSIONS The results suggest that increased inflammatory potential of diet, as indicated by higher DII score, is associated with elevated levels of chemerin and LBP. While DII was positively associated with FBS, no significant correlation was found for insulin and other indices of IR.

Abstract
BACKGROUND Older people are more likely to develop nutritional problems and timely diagnosis of malnutrition is crucial to prevent hazardous consequences following poor nutrition. AIMS To evaluate the efficacy of Geriatric Nutritional Risk Index (GNRI) to assess nutritional status among non-hospitalized elderly, compared to mini nutritional assessment (MNA) among Iranian seniors. METHODS One hundred and sixty-four subjects, aged ≥ 65 years old were recruited to our cross-sectional study from various districts of Tabriz (Tabriz, Iran). Anthropometric and biochemical measurements were performed, short- and long-form MNAs and GNRI were assessed in our study subjects. Sensitivity, specificity and predictive values of the three indices, agreement between them, and their correlation with anthropometric and biochemical parameters were evaluated. Receiver-operating characteristic (ROC) curve analysis was performed to determine the optimal cut-off point for GNRI in our study population. RESULTS GNRI had lower sensitivity (50, 57%), but optimal specificity (94, 93%) and lower negative predictive value (NPV; 68, 71%) compared to MNA-LF and MNA-SF, respectively. We found a moderate agreement between GNRI and MNA-SF (K = 0.52) and MNA-LF (K = 0.46) scores. Significant correlations were observed between re-categorized MNAs as well as GNRI scores, and age, weight, MAC, CC, WC, albumin, and pre-albumin. The cut-off point of 110.33 was obtained for GNRI, according to the ROC curve. CONCLUSIONS Although GNRI may not be an efficient tool for screening malnutrition due to its lower sensitivity, it is moderately correlated with MNAs and also more useful when limited funding needs to target the truly malnourished seniors.

Abstract
It is still unclear whether toll-like receptor (TLR) signaling and serum levels of inflammatory markers in metabolically unhealthy abdominally obese (MUAO) are due to their obesity and/or their metabolic state. We hypothesized that abdominal obesity is an important mediator of the association of metabolic state with TLR signaling and serum inflammatory markers. Therefore, in this case-control study, we compared the expression levels of TLR4 and Toll/interleukin-1 receptor domain containing adaptor protein-inducing interferon β (TRIF) and serum concentrations of interferon β and lipoprotein-binding protein (LBP) in metabolically healthy abdominally obese (MHAO) and MUAO individuals. Basal blood samples from 65 abdominally obese subjects with waist circumference (WC) of at least 95 cm were collected to determine serum metabolic parameters, IFNβ, and LBP. Those with 3 or more metabolic alterations were defined as MUAO (n = 34), and those having 2 or less were classified as MHAO (n = 31). Furthermore, messenger RNA (mRNA) was isolated from peripheral blood mononuclear cells. TLR4 and TRIF gene expression assay was performed using quantitative real-time polymerase chain reaction. There were significant differences in serum fasting blood sugar (P = .017), triglyceride (P < .001), cholesterol (P = .002), and low-density lipoprotein cholesterol (P = .034) between the MUAO and MHAO groups, whereas no significant difference was observed in the expression ratio of TLR4 and TRIF mRNA and serum levels of IFNβ and LBP. However, a significant correlation was noticed between mRNA expression levels of TLR4 and TRIF (r = 0.50, P < .001) and serum IFNβ and LBP (r = 0.70, P < .001). It is concluded that the expression levels of TLR4 and TRIF as well as serum IFNβ and LBP are more related to abdominal obesity than to metabolic health.

Abstract
Type 2 diabetes mellitus (T2DM) can lead to major complications such as psychiatric disorders which include depressive and anxiety-like behaviors. The association of the gut-brain axis in the development of such disorders, especially in T2DM, has been elucidated; however, gut dysbiosis is also reported in patients with T2DM. Hence, the regulation of the gut-brain axis, in particular, the gut-amygdala, as a vital region for the regulation of behavior is essential. Thirty-five male Wistar rats were divided into six groups. To induce T2DM, treatment groups received high-fat diet and 35 mg/kg streptozotocin. Then, supplements of Lactobacillus plantarum, inulin or their combination were administered to each group for 8 weeks. Finally, the rats were sacrificed for measurement of blood and tissue parameters after behavioral testing. The findings demonstrated the favorable effects of the psychobiotics (L. plantarum, inulin or their combination) on oxidative markers of the blood and amygdala (superoxide dismutase, glutathione peroxidase, malondialdehyde and total antioxidant capacity), as well as on concentrations of amygdala serotonin and brain-derived neurotrophic factor, in the diabetic rats. In addition, beneficial effects were observed on the elevated plus maze and forced swimming tests with no change in locomotor activity of the rats. There was a strong correlation between the blood and amygdala oxidative markers, insulin and fasting blood sugar with depressive and anxiety-like behaviors. Our results identified L. plantarum ATCC 8014 and inulin or their combination as novel psychobiotics that could improve the systemic and nervous antioxidant status and improve amygdala performance and beneficial psychotropic effects.

Abstract
Background: To identify the association of total diet and individual meals with gastroesophageal reflux disease (GERD). Methods: This age- and sex-matched case-control study was carried out among 217 subjects (106 cases and 111 controls). Data were collected using a demographic questionnaire and a GERD checklist and a 3-day food record. Results: Cases consumed more fat (median: 26.3 [3.2-71.5] g vs. 21.8 [4.3-58.1] g; P=0.04)and more energy percent form carbohydrates (median: 72.5 [0-100] vs. 69.0 [0-100]; P=0.02)at lunch, and less energy (median: 129.5 kcal [0-617.6] vs. 170.5 kcal [0-615.7]; P=0.01) and protein (2.4 [0-19.4] g vs. 3.1 [0-21.8] g; P=0.01) at evening snack, compared to controls.The volume of food was significantly different between the two group only at lunch (median:516 [161-1292] g vs. 468 [198-1060] g; P=0.02). The percentage of energy from total dietary protein showed a significant association with GERD after adjusting for confounders (odds ratio[OR]=0.89; 95% CI: 0.81-0.98). Regarding the individual meals, amount of fat consumed at lunch (OR=1.02; 95% CI: 1.00-1.05), and amount of protein intake at evening snack (OR=0.92;95% CI: 0.85-1.00) were significantly associated with GERD. Meanwhile, caloric density and meal frequency did not differ significantly between the two groups. Conclusion: Amount of fat consumed at lunch is positively associated with GERD, whereas the percentage of energy from total protein and amount of protein intake at evening snack are more likely to be inversely associated with GERD.

Abstract
BACKGROUND & AIMS Only a limited number of studies have compared nursing home and community residing elderly in terms of health-related issues. The present study aimed to compare nutritional status and its associated factors between nursing home residents and community-dwelling seniors. METHODS In this case-control, age- and gender-matched study in Tabriz (East Azarbaijan, Iran), elderly subjects aged 65 years and older were recruited from nursing homes (n = 76) and community (n = 88). Anthropometric, blood pressure and dietary intake measurements, as well as biochemical assays were performed. Nutritional status (Mini Nutritional Assessment: MNA), cognitive function (Mini Mental State Examination: MMSE) and physical performance (Barthel Index) were assessed and compared between the two settings. RESULTS Nursing home residents had significantly lower body mass index (BMI), limbs, waist and hip circumferences, and diastolic blood pressure. Caloric and protein intake of the groups were similar, while nursing home residents received lower amounts of many micronutrients and saturated fats and higher polyunsaturated fats. MNA, MMSE and Barthel index scores were significantly different between the groups, all of them in favor of the free living elderly (p < 0.001, p < 0.001 and p = 0.014, respectively). Laboratory tests revealed significantly lower levels of hemoglobin, folate, fasting blood sugar, insulin, albumin, prealbumin, creatinine and uric acid in the nursing home group; however, mean cell volume (MCV) and HDL-cholesterol were higher in this group. CONCLUSION Elderly people living in nursing homes have lower BMI, suffer from many nutritional deficiencies and are predisposed to malnutrition, impaired cognition and deteriorating physical performance, compared to community dwelling seniors.

Abstract
OBJECTIVES This study aimed to compare serum free fatty acids (FFAs) and lipopolysaccharide-binding protein (LBP) between metabolically healthy abdominally obese (MHAO) and metabolically unhealthy abdominally obese (MUAO) individuals. We also examined the association between serum FFAs and LBP in the participants. METHODS In this age-matched and gender-matched case-control study, 164 abdominally obese subjects were recruited from June to November 2015 in the northwest of Iran. Demographic data, dietary intake, body composition, anthropometric indices and physical activity (PA) were assessed. Basal blood samples were collected to determine serum metabolic parameters, FFAs and LBP. Abdominal obesity was defined as having waist circumference ≥95 cm. Those with three or more metabolic alterations were defined as MUAO and those having two or less were classified as MHAO. Data were analysed using SPSS V.17.0. RESULTS There were no significant differences in dietary intake, anthropometric indices, body composition and PA between the two groups. The odds of MUAO significantly increased by increments in serum fasting blood sugar (OR 3.79, 95% CI 2.25 to 6.40), triglycerides (OR 1.10, 95% CI 1.05 to 1.15), systolic blood pressure (OR 1.02, 95% CI 1.00 to 1.04) and diastolic blood pressure (OR 1.03, 95% CI 1.01 to 1.06) and decreased by increase in serum high-density lipoprotein cholesterol (OR 0.32, 95% CI 0.20 to 0.52). The levels of LBP and FFAs showed no significant differences between the two groups. However, significant correlations were found between LBP and FFAs in pooled population (r=0.712; p<0.001) as well as in cases (r=0.717; p<0.001) and controls (r=0.704; p<0.001). Neither FFAs nor LBP were significantly correlated with dietary intake or metabolic parameters (p>0.05). CONCLUSION The results indicated that serum LBP and FFAs are highly correlated both in MHAO and MUAO states. In addition, the levels of LBP and FFAs seem to be more related to abdominal obesity than to the presence or absence of metabolic health.

Abstract
Background In recent years, a great attention has been focused on Spirulina platensis as a source of potential valuable nutrients for prevention and treatment of chronic diseases. The objectives of the current study were to determine the effects of Spirulina platensis on anthropometric parameters, serum lipids, appetite and serum Vascular Endothelial Growth Factor (VEGF) in obese individuals. Methods In the current study sixty four obese individuals aged 20–50 years were enrolled and randomly allocated into two groups of intervention and placebo. Intervention group (n = 29) received each 500 mg of the Spirulina platensis a twice-daily dosage while the control group (n = 27) received two pills daily starch for 12 weeks. Anthropometric parameters and serum VEGF and lipid profile were measured in fasting blood samples at the beginning and end of the study period. Dietary intakes were assessed by a 24-h recall method and appetite was measured using standard visual analogue scale (VAS). Results Body weight and body mass index (BMI) were decreased in intervention and placebo treated groups although the mean reduction in Spirulina platensis-treated group was significantly higher (P < 0.05). Serum total cholesterol (TC) significantly reduced in intervention group (P < 0.05). Also, treatment with Spirulina platensis significantly reduced appetite (P = 0.008). Mean serum VEGF, low density lipoprotein-cholesterol, and triglycerides did not change significantly after intervention. Serum high density lipoprotein-cholesterol concentrations (HDL-c) significantly increased in both groups while no difference in mean difference of this change has been observed. Conclusion Spirulina supplementation at a dose of 1 g/d for 12 weeks is effective in modulating body weight and appetite and partly modifies serum lipids. This can further confirm the efficacy of this herbal supplement in control and prevention of obesity and obesity- related disorders.

Abstract
This cross-sectional study was aimed to better clarify the associations of insulin resistance (IR) with endocrinometabolic parameters in polycystic ovary syndrome (PCOS). Anthropometric measurements, endocrine and metabolic profiles, and the presence of IR and metabolic syndrome (MetS) were assessed in 63 overweight or obese PCOS patients subdivided into insulin-resistant (IR) and insulin-sensitive (IS) groups. Fasting insulin concentration and HOMA-IR were higher (p<0.001), and quantitative insulin check index (QUICKI), glucose-to-insulin ratio (p<0.001), and high-density lipoprotein cholesterol (HDL-C) (p=0.012) were lower in IR group. MetS (p=0.034) and obesity (p=0.038) were more prevalent in IR group. For all PCOS patients, significant correlations of total cholesterol (TC) with dehydroepiandrosterone sulphate (DHEAS) (r=-0.27, p=0.031), HDL-C with QUICKI (r=0.26, p=0.036) were found. Partial correlations also showed significant associations between TG and BS2h (r=0.30, p=0.026) as well as TC and LH/FSH ratio (r=0.30, p=0.032). When the patients were divided into IR and IS groups, significant correlations of low-density lipoprotein cholesterol (LDL-C) with luteinizing hormone (LH) (r=0.50, p=0.017) as well as TC (r=0.42, p=0.043) and LDL-C (r=0.50, p=0.016) with LH/FSH ratio were observed in IR group. However, partial correlation suggested significant associations of HDL-C with testosterone (r=-0.35, p=0.049) as well as serum LDL-C (r=0.38, p=0.033), HDL-C (r=-0.32, p=0.047), and TC (r=0.34, p=0.056) with progesterone level only in the IS group. The findings of this study indicated that lipid abnormalities may occur in PCOS, irrespective of IR.

Abstract
AIM We aimed to evaluate the effects of raw red onion consumption on metabolic features in overweight and obese women with polycystic ovary syndrome. MATERIAL AND METHODS In this randomized controlled clinical trial, the patients (n=54) were randomly allocated to the intervention group as 'high-onion' (raw red onions: 2 × 40-50 g/day if overweight and 2 × 50-60 g/day if obese) or to the control group as 'low-onion' (raw red onions: 2 × 10-15 g/day) along with limited liliaceous vegetables for 8 weeks. Body mass index, dietary record, and metabolic parameters (fasting blood sugar, triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and lipoprotein (a)) were evaluated in the follicular phase of the menstrual cycle at baseline and after 8 weeks. Hormonal variables (progesterone, prolactin, and 17-OH progesterone) were also measured at baseline. RESULTS Onion significantly decreased the levels of total cholesterol within each group; however, these changes were stronger in the high-onion group (weighted mean differences [WMD]: -5.60 [95% confidence interval [CI]: -9.16, -2.03]; P=0.003) than in the low-onion group (WMD: -6.42 [95%CI: -11.97, -0.87]; P=0.025). Similarly, low-density lipoprotein cholesterol decreased significantly (WMD: -5.13 [95%CI: -9.46, -0.81); P=0.022) in the high-onion group, and (WMD: -2.90 [95%CI -5.57, -0.21]; P=0.035) in the low-onion group after treatment. The levels of fasting blood sugar, triglycerides, high-density lipoprotein cholesterol and lipoprotein (a) did not differ significantly after 8-week onion treatment. Adjustment for confounders did not make any significant changes in any of the parameters in post-treatment levels. CONCLUSION Raw red onion consumption appears to be effective as a cholesterol-lowering food agent in women with polycystic ovary syndrome. However, further investigation is warranted.

Abstract
BACKGROUND The present study was aimed to investigate lipid profile in relation to anthropometric indices and insulin resistance in overweight or obese women with polycystic ovary syndrome (PCOS). METHODS In this cross-sectional study, lipid profile and anthropometric indices including body mass index (BMI), waist and hip circumference, waist to hip ratio (WHR), and waist to height ratio (WHtR) were evaluated in 63 overweight or obese PCOS patients subdivided into insulin-resistant (IR) and non insulin-resistant (NIR) groups. IR was defined as homeostasis model of insulin resistance (HOMA-IR) ≥3.8. RESULTS Fasting insulin concentration and HOMA-IR were higher (P<0.001) and high-density lipoprotein cholesterol (P=0.012) was lower in IR group. All of the anthropometric measures other than WHR and BMI showed significant correlations with several lipid parameters. Amongst, WHtR showed the strongest correlation with total cholesterol (TC) (r=0.37; P=0.004) and low density lipoprotein cholesterol (LDL-C) (r=0.33; P=0.011) in the whole PCOS patients. CONCLUSION Anthropometric characteristics (especially BMI and hip circum-ference) are more important parameters correlated to lipid profile than IR in overweight or obesePCOS patients, confirming the importance of early treat-ment of obesity to prevent dyslipidemia in the future.

Abstract
The present study was aimed to identify the association of overweight and obesity with gastroesophageal reflux disease (GERD). This age- and sex-matched case-control study was carried out in a sample of subjects referred to the specialized clinic of Tabriz University of Medical Sciences from November 2006 to March 2007. Data were collected using a demographic questionnaire and a checklist to determine reflux symptoms. Weight and height were measured and Body Mass Index (BMI) was calculated. Logistic regression was used to examine the association between overweight, obesity and reflux symptoms. The study population included 106 cases (with reflux symptoms) and 111 controls with a mean age of 35.2 +/- 12.9 years. The mean BMI was 2.4 units greater in cases than controls (p = 0.0001). In unadjusted model, overweight (OR = 3.41, CI: 1.8-6.44) and obesity (OR = 2.84, CI: 1.38-5.82) were significantly associated with GERD. Results of multivariate logistic regression revealed significant association between overweight and GERD after adjusting for confounders (OR = 2.87, CI: 1.49-5.53). Given the increasing prevalence of patients with both overweight/obesity and GERD, Serious dietary intervention studies for weight loss as a therapeutic strategy should be carried out in GERD patients complicated with obesity.
