Filter by: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 investigators are studying the pathophysiologic links between obesity, insulin resistance (IR), adipose tissue infection, and post-acute sequelae of COVID-19 (PASC). This study looks at whether adipose (fat) tissue contributes to PASC by driving chronic inflammation or by serving as a reservoir for SARS-CoV-2 persistence. The results will not only determine whether obesity and IR are risk factors for PASC, but will also define fundamental biology that sets the stage for the investigation of novel or existing therapies that target the causal pathways identified.
The aim of this study is to determine the prevalence of Insulin Resistance (IR) among overweight and obese adolescents using HOMA-IR scores and identify lifestyle risk factors in the IR and Non-IR group.
In this project the investigators will test if it is possible to measure changes in intestinal gas production after supplementation of a complex fiber mixture over a 36 hour period in both lean normoglycemic individuals and individuals with insulin resistance and/or prediabetes with overweight when compared with a placebo Changes in intestinal gas production will also be related to energy expenditure, substrate metabolism, microbial composition and related metabolites in feces, blood and urine.
Background: Obesity and related illnesses cause at least 2.8 million deaths each year worldwide. Few treatments exist for obesity that are safe and widely available. A study drug (mirabegron [MG]) combined with a supplement (alpha-lipoic acid [ALA]) may help. Objective: To learn how MG and ALA can help the body process food. Eligibility: People aged 18 to 65 years with a body mass index between 30 and 40 kg/m2. Design: Participants will be screened. They will have a physical exam. They will have blood and urine tests and a test of their heart function. They will speak with a dietician. The study has two phases. Each phase begins with a 2-day stay in the clinic; then the participant will take the study drugs at home for about 4 weeks, followed by another 2-day stay in the clinic. They will also have outpatient visits about 2 weeks after each clinic stay. During the clinic stays, participants will undergo many tests: They will have a plastic tube (catheter) inserted into a vein in each arm. These will be used to draw blood and to infuse glucose (sugar) and insulin. They will have imaging scans. They will have a clear hard plastic shield placed over their head to measure oxygen and carbon dioxide as they breathe. Participants will take the study drugs at home. Both MG and ALA are taken by mouth with water. During one phase, participants will take MG plus a placebo. A placebo looks like the study drug but doesn t contain medicine. They will log their diet, exercise, and sleep....
The study aims to investigate the effects of oral inositols on insulin-resistance and metabolic variables (triglycerides, total cholesterol, HDL cholesterol) in children aged 8-12 years with obesity and insulin-resistance.
We designed a study to determine if ovarian volume (OV) and/or follicle number (FN) are independently associated with abnormal metabolic findings in women diagnosed with PCOS. We hypothesized that ovarian morphology but not follicle number would be associated with a significantly higher odds of hyperinsulinemia among women with PCOS.
Although, a number of drugs are promising treatment strategies for insulin resistance, a critical question arises to which drug benefits patients with type 2 diabetes more from reduced insulin resistance and consequent glycemic control. In this study, we aim to evaluate the effect of metformin, dapagliflozin and the fixed-dose combination of metformin and pioglitazone (500mg metformin plus 15mg pioglitazone) on insulin sensitivity and glycemic control in overweight patients with newly diagnosed type 2 diabetes.
Preoperative carbohydrates (CHO) supplement has been shown to alleviate postoperative insulin resistance (IR) in nondiabetic patients undergoing a variety of surgeries. However, it remains controversial whether preoperative CHO could yield similar effects in diabetic patients. Thus, the investigators design a randomized controlled trial investigating the impact of preoperative CHO on postoperative IR and clinical outcomes in diabetic patients undergoing cardiac surgery. The results of the study may give some clinical implications and further improve perioperative care for diabetic patients.
