RESUMO
BACKGROUND: In the present systematic review and meta-analysis, the association of maternal exposure to the endocrine disrupting chemicals (EDCs) with cardio-metabolic risk factors in children during childhood for the first time. METHOD: The PubMed, Scopus, EMBASE, and Web of Science databases were systematically searched, up to Feb 2023. In total 30 cohort studies had our inclusion criteria. A random-effects model was used for the variables that had considerable heterogeneity between studies. The Newcastle-Ottawa Scale (NOS) tool was used to classify the quality score of studies. All statistical analyses were conducted using Stata 14 and P-value < 0.05 considered as a significant level. RESULTS: In the meta-analysis, maternal exposure to the EDCs was weakly associated with higher SBP (Fisher_Z: 0.06, CI: 0.04, 0.08), BMI (Fisher_Z: 0.07, CI: 0.06, 0.08), and WC (Fisher_Z: 0.06, CI: 0.03, 0.08) z-scores in children. A significant linear association was found between maternal exposure to the bisphenol-A and pesticides with BMI and WC z-score in children (p < 0.001). Subgroup analysis showed significant linear association of BPA and pesticides, in the urine samples of mothers at the first trimester of pregnancy, with BMI and WC z-score in children from 2-8 years (p < 0.05). CONCLUSION: Prenatal exposure to the EDCs in the uterine period could increase the risk of obesity in children. Maternal exposure to bisphenol-A and pesticides showed the strongest association with the obesity, especially visceral form, in the next generation.
RESUMO
Background: Diabetes mellitus (DM) is a category of metabolic conditions affecting about 5% of people worldwide. High mortality associated with DM is mostly due to its severe clinical complications, including diabetic nephropathy, retinopathy, neuropathy, and cardiomyopathy. Resveratrol (RSV) is a natural, biologically active polyphenol known to have various health-promoting effects in animal models and humans. Objective: In this review, we have reviewed the preventive and therapeutic role of RSV on diabetes complications with emphasis on its molecular mechanisms of action. Methods: To prepare this review, all the basic and clinical available literatures regarding this topic were gathered through electronic databases, including PubMed, Web of Science, Scopus, and Google Scholar. Therefore, we summarized previous studies that have evaluated the effects of RSV on diabetic complications and their mechanisms. Only English language studies published up to January 2023 were included in this review. Results: RSV improves glucose homeostasis, decreases insulin resistance, induces autophagy, regulates lipid metabolism, protects pancreatic ß-cells, ameliorates metabolic disorders, and increases the GLUT4 expression. These effects induced by RSV are strongly associated with ability of this polyphenol agent to elevation expression/activity of AMP-activated protein kinase and Sirtuin 1 in various organs of diabetic subjects, which leads to prevention and therapy of diabetic complications. In addition, antioxidant and anti-inflammatory properties of RSV were reported to be involved in its action in diabetic complications, such as retinopathy and nephropathy. Conclusion: RSV is a promising compound for improving diabetic complications. However, the exact antidiabetic mechanisms of RSV need to be further investigated.
RESUMO
Background: Sodium glucose co-transporter2 (SGLT2) inhibitors have exhibited cardioprotective properties in diabetes patients. The aim of this study was to investigate the effect of Empagliflozin on changes in echocardiographic parameters. Methods: This was a post hoc analysis of the EMPA-CARD trial which was a multicenter, triple-blind randomized controlled trial. Type 2 diabetes mellitus patients with concomitant history of coronary artery disease were randomized on a 1:1 ratio into two groups receiving either 10 mg/day Empagliflozin or placebo. Patients with a history of heart failure (NYHA class 3-4) and ejection fraction (EF) < 40% were excluded. Trans-thoracic echocardiography was performed at baseline and at 26 weeks of intervention. Results: A total of 69 (Empagliflozin = 39 and placebo = 30) patients underwent echocardiography. Significant changes were observed for left ventricular ejection fraction [standard error (SE) = 0.76; beta (95% correlation interval (CrI)] = -5.558 (-7.25; -4.18) and left ventricular end-systolic volume (SE = 1.38; beta (95% CrI) = 3.915 (1.2; 0.66). Other echocardiographic parameters relating to right ventricular or atrial function did not change significantly. Conclusion: Empagliflozin can have cardioprotective benefits in subjects without HF. Further studies are required to determine the effect of Empagliflozin in non-HF patients. Trial registration: The original EMPA-CARD study has been registered in Iranian Registry of Clinical Trials. www.IRCT.ir, Identifier: IRCT20190412043247N2. Registration Date: 6/13/2020. Registration timing: prospective.
RESUMO
Introduction and objectives: Aging is an irreversible process associated with decreased biological functions that can lead to the reduction of reproductive organs capacities in males and females. Paternal age is a significant predictor of offspring health and development. So, the aim of this study was to evaluate the effects of vitamin C on histopathological and biochemical testicular changes following aging process with a focus on stereological methods. Material and methods: For this study, 48 adult male NMRI mice were divided into two control and experimental groups. Mice in experimental group were supplemented with vitamin C (150mg/kg) including 24-h interval by oral gavage for 33 weeks. Same regime was performed for animals in control group except that vitamin C was replaced by water. Then, right testes were extracted for stereological and left testes were used for molecular analyses on weeks 8, 12, and 33. (AU)
Introducción y objetivos: El envejecimiento es un proceso irreversible asociado a una disminución de las funciones biológicas que puede conducir a la reducción de la capacidad de los órganos reproductivos en hombres y mujeres. La edad paterna es un predictor significativo de la salud y el desarrollo de la descendencia. Por lo tanto, el objetivo de este estudio fue evaluar los efectos de la vitamina C sobre los cambios testiculares histopatológicos y bioquímicos posteriores al proceso de envejecimiento con un enfoque en los métodos estereológicos.Material y métodos: Para este estudio, 48 ratones NMRI machos adultos se dividieron en dos grupos de control y experimentales. Los ratones del grupo experimental se suplementaron con vitamina C (150mg/kg), incluido un intervalo de 24 horas mediante sonda oral durante 33 semanas. Se realizó el mismo régimen para los animales del grupo de control, excepto que se reemplazó la vitamina C por agua. Luego, se extrajeron los testículos derechos para estereología y los testículos izquierdos se utilizaron para análisis moleculares en las semanas 8, 12 y 33. (AU)
