Circulating levels of adropin and overweight/obesity: a systematic review and meta-analysis of observational studies.

The association between circulating adropin levels and overweight/obesity is currently unclear. The aim of this study was thus to investigate and seek to determine the association between circulating adropin levels and overweight/obesity using the meta-analysis approach of observational studies. A comprehensive literature search was carried out through the PubMed, Web of Science, and SCOPUS databases to identify relevant observational studies that assessed the relationship between circulating adropin levels and overweight/obesity up to September 2020.

The effect of vitamin C supplementation on mood status in adults: a systematic review and meta-analysis of randomized controlled clinical trials.

Objective: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to clarify the effect of vitamin C supplementation on mood in both depressed and non-depressed populations.

Methods: A systematic search of PubMed, EMBASE, ISI web of science and Scopus databases was conducted, from inception to 1 March 2020. Random-effects meta-analyses were used to estimate the effect size (as Hedge's g) of vitamin C supplementation on depressive symptoms.

Effect of DASH diet on oxidative stress parameters: A systematic review and meta-analysis of randomized clinical trials.

Background And Aims: Oxidative stress (OS) is one of the main risk factors for several chronic diseases. The Dietary Approaches to Stop Hypertension (DASH) contain many antioxidants and may contribute to managing OS.

Objective: To perform a systematic review and meta-analysis to examine the impacts of the DASH diet on OS parameters.

Serum irisin levels in metabolically healthy versus metabolically unhealthy obesity: A case-control study.

Metabolically healthy obese (MHO) individuals appear to be protected or more resistant to the progression of obesity-related metabolic disorders. Hormonal regulation associated with adipose or muscular tissues such as irisin and leptin may facilitate the healthy metabolic profile of MHO cases. In this case-control study, the differences between serum level of irisin was investigated in metabolically unhealthy obese (MUO) and metabolically healthy obese (MHO) individuals.

Zinc in depression: From development to treatment: A comparative/ dose response meta-analysis of observational studies and randomized controlled trials.

Background: A previous meta-analysis suggested that zinc status may be linked to depression status. However, it remains unclear whether zinc status can predict the risk of depression development, or whether the monotherapy of zinc is superior to the combination of zinc supplementation and antidepressant medications in the treatment of depression. Therefore, this meta-analysis aimed to clarify the impact of zinc status and supplementation on depression development and status across all available evidence.

Effects of zinc, vitamin D, and their co-supplementation on mood, serum cortisol, and brain-derived neurotrophic factor in patients with obesity and mild to moderate depressive symptoms: A phase II, 12-wk, 2 × 2 factorial design, double-blind, randomized, placebo-controlled trial.

Objective: The aim of this study was to investigate the effects of zinc, vitamin D, and their co-supplementation versus placebo on changes in the Beck Depression Inventory II (BDI-II) score, serum cortisol level, and brain-derived neurotrophic factor (BDNF) in obese/overweight patients with depressive symptoms.

Method: This 2 × 2 factorial, double-blind, randomized, placebo-controlled trial with obese/overweight patients with depressive symptoms was conducted in the Endocrinology and Metabolism Research Center (EMRC), Vali-Asr, Emam Khomeini Hospital between July 2016 and February 2017. The intervention period was 12 wk.

Comparing serum concentration of spexin among patients with metabolic syndrome, healthy overweight/obese, and normal-weight individuals.

There are many factors related to etiology of metabolic syndrome (MetS) including obesity. Spexin, a peptide hormone released from adipose tissue, is the most down-regulated gene in obese, compared to non-obese adipose tissue. Hence, it potentially contributes to the progression and development of metabolic diseases.

Adiponectin: An Indicator for Metabolic Syndrome.

Background: Metabolic syndrome (MetS), a cluster of cardiometabolic risk factors, consider as a manifestation of obesity. However, a proportion of obese patients do not develop MetS. The aim of our study was to determine whether concentration of plasma adiponectin and leptin differ between metabolic unhealthy obese (MUO) patients and comparable age- and sex-matched control groups.

Depressive symptoms among metabolically healthy and unhealthy overweight/obese individuals: a comparative study.

Although a growing body of evidence suggests an association between obesity and depressive disorder, the association remains inconclusive. Metabolically healthy obese (MHO) phenotype, defined by favorable lipid profile, and normal insulin sensitivity, blood pressure, may be considered as a possible explanation for these inconsistencies. Accordingly, this study aimed to compare depression score among metabolic unhealthy obese (MUO) and age- and sex-matched healthy controls.

The Effects of Probiotics or Synbiotics Supplementation in Women with Polycystic Ovarian Syndrome: a Systematic Review and Meta-Analysis of Randomized Clinical Trials.

We searched bibliographic databases from inception through May 2018 to evaluate the effect of probiotics (or synbiotics) supplementation in women suffering from polycystic ovary syndrome (PCOS). Seven trials involving 236 women with PCOS and 235 controls were included in the meta-analysis. Comparing with the control group, probiotics (or synbiotics) may improve Quantitative insulin sensitivity check index (QUICKI) (standardized mean difference (SMD) 0.

Adropin- A Novel Biomarker of Heart Disease: A Systematic Review Article.

Background: Heart disease is one of the most common chronic disease and leading cause of morbidity and mortality worldwide. Adropin, a newly identified protein, is important for energy homeostasis and maintaining insulin sensitivity, and has been referred to as a novel regulator of endothelial cells. Endothelial dysfunction is a key early event in atherogenesis and onset of HD.

Metabolic Syndrome Patients Have Lower Levels of Adropin When Compared With Healthy Overweight/Obese and Lean Subjects.

Metabolic syndrome (MetS), a cluster of cardiometabolic risk factors, is a challenging public health issue. The aim of current study was to test the hypothesis that concentrations of plasma adropin and leptin differ between patients with MetS and comparable age- and sex-matched control groups. This case-control study involved 153 subjects (51 per group).

Diet quality in obese/overweight individuals with/without metabolic syndrome compared to normal weight controls.

Background: Metabolic syndrome (MetS) is a serious public health concern worldwide; however, the pathogenesis of this disease has not been yet cleared. This study aimed to compare diet quality in obese/overweight participants with/without metabolic syndrome with normal weight controls.

Methods: This was a comparative study on 147 Iranian adults under treatment at the Endocrinology Center of Tehran University of Medical Sciences.

Positive evidence for vitamin A role in prevention of type 1 diabetes.

Type 1 diabetes mellitus (T1DM) as one of the most well-known autoimmune disease, results from the destruction of β-cells in pancreas by autoimmune process. T1DM is fatal without insulin treatment. The expansion of alternative treatment to insulin is a dream to be fulfilled.
