Active clinical trials for "Glucose Intolerance"

Obesity and its metabolic complications are leading causes of global morbidity and mortality. Evidence is mounting that inappropriate timing of food intake contributes to obesity. Specifically, late eating is associated with greater weight gain and metabolic syndrome. However, the mechanism by which late eating harms metabolism is not fully understood but may be related to mis-timing of food intake in relation to the body's endogenous circadian rhythm. Conversely, harmonization of eating timing with endogenous circadian rhythm may optimize metabolic health. In this study the investigators will use gold-standard methods of characterizing circadian rhythm in humans to examine the metabolic impacts food timing relative to endogenous circadian rhythm.

The purpose of this study is to determine whether modifying the timing of nutrition support from overnight to daytime enhances sleep quality, preserves circadian rhythms, and improves overall inflammation and cardiometabolic profiles in postoperative patients in the cardiac surgical ICU on enteral nutrition.

This study is designed to test whether non-persistent environmental chemicals (PECs) are elevated in people with glucose dysregulation. The primary aim is to measure whether this toxicant burden can be reduced using a dietary and lifestyle modification intervention. The secondary aim is to observe any changes in glucose response pre and post-intervention.

This project is designed to test for the first time whether glucose metabolism is differentially impaired by sleep restriction with and without additional exposure to artificial light at night (ALAN).

The aim of the study is to demonstrate that a daily supplementation of AP029 Mix: I) has a positive effect on reducing side effects of metformin, while enhancing the therapeutic effect of metformin; II) normalizes prediabetes biomarkers in order to prevent further progression into diabetes.

The goal of this study is to uncover sleep and circadian mechanisms contributing to adverse metabolic health. The protocol is a 21 day (7 outpatient days, 14 inpatient days) mechanistic randomized-crossover study designed to identify the impact of chronic sleep restriction and circadian timing, independently and in combination on energy metabolism and identify the independent and combined effects on glucose tolerance.

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: Does the addition of excess carbohydrates when transitioning to a sedentary lifestyle promote insulin resistance in fit young men? 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?

This study is designed to explore the effect of mango consumption on glycemic indices, cardiovascular health, and body composition in overweight and obese individuals with prediabetes.

The study aims to investigate the genetic basis of the response to short-term (3 months) orally administered semaglutide treatment, in terms of improving metabolic parameters, including the hormonal response to a standardized meal, and changes in body composition and liver steatosis. In the study, parameters such as fasting and 2-hour glucose during OGTT, HbA1c, body fat mass, body weight, total cholesterol, HDL and LDL, triglycerides, HOMA-IR, Matsuda Index and liver steatosis will be assessed. All the patients will undergo genome-wide genotyping. Moreover, in a subset of participants, muscle and fat biopsies will be performed, before and after the treatment, and liver, muscle and pancreas fat content will be assessed using MRI.

This study will investigate how maternal emotional state following a controlled stress exposure in pregnancy influences blood glucose and insulin levels after eating a standardized meal, and whether the effects of emotional state on blood glucose and insulin is different after eating a healthy meal (low GI) compared to a less healthy meal (high GI).
