Active clinical trials for "Insulin Resistance"

Insulin resistance is defined as a decrease in the ability of insulin to lower blood glucose levels. Various pathological conditions can cause an increase in insulin resistance, such as sepsis, administration of certain medications, various stressful situations, surgery or significant injuries, etc. Sepsis can cause extreme stress, which causes significant changes in metabolism, disruption of blood glucose regulation and increased insulin resistance. In sepsis there is an extreme activation of inflammatory mediators and of counter-regulatory hormones, such as cortisol, glucagon and catecholamines, which increase hepatic gluconeogenesis on the one hand, and increase the peripheral resistance to insulin on the other hand. Disorder in the regulation of blood glucose level causes increased mortality and morbidity among intensive care unit patients with sepsis, as well as an increase in the duration of hospitalization and its financial expenses. There are a number of parameters used in the intensive care unit to diagnose the development of sepsis within the unit, such as an increase or decrease in body temperature, an increase in CRP level, white blood cell count, pro-calcitonin level, etc It is possible that an increase in insulin resistance can also be used as a predictor of sepsis. It should be noted that almost all patients hospitalized in the intensive care unit are treated with a continuous infusion of insulin to balance their blood glucose level, including patients who are not diagnosed with diabetes prior to their hospitalization in the unit. This is in light of the increase in insulin resistance for the reasons listed above among patients in critical condition, and also due to the need to maintain blood glucose values in the range of 140-180 mg/dl, since high blood glucose values among patients hospitalized in the intensive care unit are associated with increased morbidity and mortality. We would therefore like to investigate whether an increase in insulin resistance, as expressed in an increase in the patient's insulin intake, can predict the development of sepsis secondary to bacteremia in the intensive care unit.

Breast cancer is the most common cancer type in European women. Patients treated for early non-metastatic breast cancer comprise a growing group of survivors due to early diagnosis and improved treatment. Many of these survivors experience adverse effects such as decreased bone mineral density, derangement of metabolic markers (fat, glucose, insulin) and increased blood pressure. Increasing risk of bone fracture and cardiometabolic disease (eg. diabetes mellitus type 2). The purpose of this study is to identify mechanisms behind cardiometabolic changes that may be connected to the (neo-)adjuvant treatment. On top of this we hope to indentify potential biological markers that can help prevent development of metabolic disease. We will be recruiting 120 post-menopausal women age 50-70 with early breast cancer and 1-2 times a year for 5 years examine bone mineral density, body composition, glucose and fat metabolism and nerve damage. A questionnaire will be used to collect information on diet, physical activity and quality of life. Derudover anvendes spørgeskemaer til at indsamle information vedrørende. This new knowledge will help clinicians start adequate preventive measures to help patients avoid cardiometabolic disease secondary to cancer treatment.

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 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

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

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.

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.

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.
