Filter by:Policystic ovary syndrome is the most common endocrinopthy during reproductive period. One of the factors implicated in the pathogenesis is insulin resistance. Asprosin, which is secreted from white adipose tissue is a new candidate for insulin resistance. Myoinositol is known to reduce insulin resistance in PCOS patients. The effect of myoinsitol on serum asprosin levels is unknown yet. This study aimed to evaluate the effect of myoinositol on serum asprosin levels in PCOS patients.
The study aims to investigate the relationship between fasting insulin and Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) across various demographic factors, including age, sex, race/ethnicity, BMI, and polycystic ovary syndrome (PCOS) diagnosis. By analyzing these variables, the study seeks to identify potential variations in insulin levels, which could provide valuable insights into the impact of different factors on metabolic health and the development of insulin-related conditions.
The findings will serve as a reference for clinical professionals to promote exercise among the general population and will provide evidence of whether different exercise amounts are recommended for individuals with different BMIs for improving HRV.
In this pilot study investigators will test the hypothesis that administration of oral probiotics modulates microbiome/metabolome, lowers leptin and insulin resistance and improves clinical parameters of asthma in obese insulin resistant asthmatics. Preliminary studies with oral probiotic administration in obese asthmatics showed increased abundance of probiotics-derived Bifidobacterium species and Bifidobacterium-derived metabolite in the airways of asthmatics. Additionally, neutrophils and IL-17 producing Th17 cells were significantly reduced following probiotics administration. Based on these preliminary studies, the investigators propose to test the following aims: Specific Aim 1: Determine if probiotic administration modulates airway microbiome/metabolome in obese insulin resistant asthmatics Specific Aim 2: Determine if modulation of leptin levels and insulin sensitivity by probiotics administration correlates with airway metabolome alterations and weight loss in obese insulin resistant asthmatics Specific Aim 3: Determine if microbiome/metabolome changes in probiotics group correlates with changes in asthma biomarkers and improved clinical outcomes compared to placebo in obese insulin resistant asthmatics.
The overall goal is to examine the efficacy of a circadian intervention in people with overweight and obesity and habitual short sleep duration (HSSD). Participants will undergo a randomized controlled trial, with circadian intervention and control (healthy lifestyle) groups. The circadian intervention is designed to reduce nighttime light exposure and after-dinner snack food intake. Alternatively, the control group will receive basic health information (e.g., physical activity, goal setting, and nutrition when eating out).
The goals of this research study are to: 1) understand why some people with obesity are protected from developing conditions such as type 2 diabetes and cardiovascular disease while others are more likely to develop obesity-related conditions; 2) assess the effect of small extracellular vesicles (sEVs also called exosomes), obtained from human participants, on metabolic function in cultured cells and in mice.
In adults with obesity seeking treatment, weight loss would ideally be composed almost exclusively of fat mass. However, loss of muscle mass and bone are unintentional consequences of weight loss, which has detrimental effects on health by lessening improvements in glucose and insulin levels, contributing to weight regain by reducing basal metabolic rate, and increasing the risk of falls, and fractures. Data in animals and humans suggest that bimagrumab, an investigational new drug for obesity that inhibits the activin type II receptor (ActRII) inhibitor, may build muscle and bone while resulting in a loss of fat mass. Semaglutide, which is FDA-approved for the treatment of obesity, results in loss of fat mass, but its effects on muscle and bone are less clear. The investigators hypothesize that in a randomized, placebo-controlled trial of 65 adults with obesity randomized to IV bimagrumab, identical IV placebo plus semaglutide, or identical IV placebo alone, bimagrumab will result in improvements in muscle, fat, and bone compared to semaglutide or placebo when given in addition to a lifestyle intervention for weight loss over 52 weeks.
Regular exercise participation is known to reduce cardiometabolic disease risk but the impact that exercise training has on adipose tissue (AT) metabolism is poorly understood, particularly in humans. It is well established that exercise training improves whole-body glucose levels and increases insulin sensitivity, and this can occur within one or two weeks. These effects are usually due to adaptations in skeletal muscle, the tissue responsible for the majority of glucose disposal. However, many studies have now determined that exercise training also results in adaptations in AT that improve whole-body metabolic health by improving glucose uptake into the AT. Skeletal muscle is thought to account for approximately 75-85% of glucose uptake , and this process is impaired in .individuals who are insulin-resistant state. It is postulated that the increased level of adiposity that accompanies severe obesity would result in higher dependency on AT for glucose uptake as the AT would be a bigger "sink". Thus the role of AT in inducing whole body insulin resistance is still unclear, particularly in individuals with obesity. This study will examine the changes in AT glucose uptake before and after 4 weeks of exercise training in obese individuals and establish if there are sex differences.
The goal of this pilot open pre-post clinical trial is to test effects of a wholegrain product in patients with newly diagnosed gestational diabetes. The main question it aims to answer is: Does the wholegrain product improve glucose tolerance and insulin sensitivity during a 75 g oral glucose tolerance test (OGTT). Participants will consume product on two consecutive evenings shortly after the first OGTT and will then perform a second OGTT. Researchers will compare the results of the first and second OGTT to see if glucose tolerance improved after consumption of the test product.
The goal of this clinical trial is to learn about the alterations insulin resistance and metabolic flexibility following a transition to an obesogenic lifestyle in fit young men. The main questions it aims to answer are: 1. Does the addition of excess carbohydrates when transitioning to a sedentary lifestyle promote insulin resistance in fit young men? 2. Does the addition of excess carbohydrates when transitioning to a sedentary lifestyle lower the body's ability to break down fats and carbohydrates in fit young men?
