Active clinical trials for "Insulin Resistance"

This study tests the effects of cannabinoid levels in blood on inflammation and insulin sensitivity both acutely and chronically in individuals across the weight spectrum. To that end, the study employs two observational designs: 1) A study of acute effects with intermittent cannabis users and 2) A study in which current cannabis users will select one of three cannabis strains for four weeks and are compared to a matched control group who do not use cannabis to study chronic effects. Blood levels of THC and CBD, inflammatory biomarkers, and insulin resistance will be measured in both studies.

The purpose of this study is to compare the effects of a low-fat, plant-based dietary intervention and a portion-controlled dietary intervention (compliant with current American Diabetes Association (ADA) guidelines) on changes in intramyocellular and hepatocellular lipid content in adults with type 2 diabetes. Changes in insulin sensitivity and glycemic control will also be assessed in this study. The study duration is 44 weeks.

In this project the investigators intend to study the therapeutic potential of a personalized fibre mixture in individuals at high risk of developing T2DM, and aim to address the following key objectives: To investigate whether a mixture of fermentable fibres, which differ in DP and side chains, will stimulate a broad range of SCFA-producing bacterial genera, resulting in enhanced chronic SCFA production throughout the whole colon with a large variation between individuals; To unravel whether providing personalized fibre mixtures, selected based on the individuals' initial microbiota and capacity for SCFA production is crucial to successfully improve host insulin sensitivity and metabolic health

The aim of the study is the effect of lifestyle modification and metformin on hypothyroidism with insulin resistance

The overarching aim of this observational study is to characterize muscle mitochondrial defects in individuals harboring pathogenic mitochondrial DNA (mtDNA) mutations associated with an insulin-resistant phenotype. In a case-control design, individuals with pathogenic mtDNA mutations will be compared to controls matched for sex, age, and physical activity level. Participants will attend a screening visit and two experimental trials including: An oral glucose tolerance test A hyperinsulinemic-euglycemic clamp combined with measurements of femoral artery blood flow and arteriovenous difference of glucose Muscle biopsy samples

The purpose of this study is to investigate whether intermittent fasting before surgery improves insulin resistance around the time of surgery, compared to carbohydrate drinks and standard fasting before surgery.

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.

Disordered sleep is a health issue with significant impacts on physical and psychological well-being that has increased in prevalence, but its impact on transgender adolescents has not been fully quantified. While there is found to be an impact of sex steroids on sleep, and sex-dependent differences in the impact of sleep duration and quality on insulin resistance (IR), there is limited available information regarding the impact of Gender Affirming Hormone Therapy (GAHT) for transgender individuals on sleep and IR. Our study aims to quantify the impacts of GAHT on sleep and IR in the pediatric transgender population as well as determine the degree of correlation of sleep to IR in this population.

The investigators aim to evaluate the effect of curcumin and virgin coconut oil extract supplementation on people with type 2 DM, including blood glucose, HbA1c levels, inflammation, body weight and insulin resistance evaluation

Background: - Innate immunity is the process by which white blood cells and other parts of the immune system sense and respond to potential infections by causing an inflammation. Researchers are interested in studying how the body responds to certain environmental factors, and whether the body s response can contribute to chronic illnesses or diseases such as asthma and certain types of cancers. Objectives: - To examine how specific genes and proteins in blood cells respond to environmental exposures. Eligibility: - Healthy volunteers between 18 and 45 years of age. Design: The study will involve one visit of 45 to 60 minutes. Participants will be screened with a brief physical examination and finger stick to determine if they are eligible to donate blood for the study, and will complete a questionnaire about any medications or other drugs (e.g., cigarettes) they may be taking. Participants will provide a blood sample for research purposes.
