Filter by:Prospective study with inclusion of bariatric surgery candidates with diagnosed Obstructive Sleep Apnea and requiring treatment with Continuous Positive Air Pressure, aiming to evaluate at 2-6-12 months after bariatric surgery whether the relationship between biometric changes (reduction in neck circumference, height, waist/hip ratio, and fat and lean mass) and the resolution of OSA is better than the relationship between these biometric changes and BMI reduction.
We will study obese hypertensive subjects in a randomized, crossover study to determine if two weeks sympathetic blockade improves endogenous glucose production. Subjects will be studied on 3 different occasions after two weeks of receiving either placebo, amlodipine (vasodilator arm) or moxonidine (study arm). The order of the studies will be determined using computer-generated randomization. Patients will be blinded as to which treatment they are receiving on each day. An investigator blinded to the treatment assignment will perform the analysis of the data.
Medical nutritional weight loss was effective in reducing body weight and waist circumference and improving a range of cardiovascular disease risk factors in obese patients, with an average effective weight loss of 11.1 kg (about 13%) over 4 months in obese adults. However, it was found through the follow-up visit that these subjects had lost only 5.8kg from baseline and regained about half of their weight (5.1 kg, 48%) after 21 months of weight-loss intervention. In this study, intestinal flora analysis was proposed to identify the causes of individual repeated weight loss failure, structure changes of weight cycling and the advantage species of flora, and explore different intestinal microbiota（microbial genomics） in ending weight loss, obesity-related genetic characteristics (SNPs loci and RNA seq), metabolite（metabolomics）and potential interaction between appetite-related hormones and weight cycling triggers. This study aimed to provide new insights for implementing personalized weight loss programs to improve the success rate of weight loss. The obese patients who failed to lose weight repeatedly were recruited from Peking Union Medical College Hospital. Research Contents:(1) Comparison of anthropometric, biochemical, energy consumption, and intestinal microbiota related indicators between groups; (2) Genotyping to screen out differential SNPs loci;(3) Analysis of the interaction between genes and environmental factors in different metabolic types of obesity. (4) A group of healthy volunteers with normal weight as the healthy control group.
The investigators are examining the extent gut permeability explains observed inflammation in normal-weight and metabolically healthy obesity (and potentially cardiovascular disease risk).
The aim of this study is to determine the effects of technology-based motivation education prepared according to the health belief model on obesity-related beliefs and attitudes, nutrition-exercise behaviors, self-efficacy and weight management in obese university students.
This study is a multicenter, randomized, double-blind, placebo-controlled, parallel phase II study to evaluate efficacy, safety, pharmacokinetics characteristics and immunogenicity of two dose levels of TG103 injection, a GLP-1 receptor agonist, in the management of overweight or obesity, to support dose selection for further development.
Obesity-related glomerulopathy (ORG) is a silent comorbidity associated with obesity whose incidence is increasing in parallel to the obesity epidemic. ORG is associated with serious health consequences including chronic kidney disease, end-stage renal disease, and increased mortality. Unfortunately, ORG has an absence of targeted therapy (except for the use of drugs blocking the renin-angiotensin system), and therefore the prognosis of this disease may be seriously compromised. Some previous studies have shown that weight loss could be effective to decrease albuminuria and reduce the declining in kidney function in subject with obesity. In line with this, in this study the investigators will evaluate the efficacy of two different dietary strategies for ORG, given the current lack of therapies for this condition. Thus, the investigators will conduct an open-label randomized controlled trial comparing a hypocaloric Mediterranean diet with a very-low calorie diet (VLCD), evaluating the efficacy on albuminuria reduction and changes in renal function. Also, the investigators will assess changes on body composition, blood pressure, markers of renal damage and inflammation, gut microbiota, and on renal ultrasound elastography.
To evaluate the effect of high intensity children's games compared with those of medium intensity on cardiac autonomic regulation, obesity biomarkers and body composition in Boys and Girls from 6 to 9 years old with Obesity or Overweight
The study looks at the comparative effects of food products made with pea, lentil, and oat flour of various particle sizes on postprandial glycemic response, appetite and food intake, and amino acid release in healthy adults.
Protocol Number: 22DK0002 Title: Effects of Ultra-processed versus Unprocessed Diets on Energy Metabolism Background: Many diets worldwide include both processed and unprocessed foods. Researchers want to study the effects these foods have on a person s health. Objective: To study how different diets affect a person s health and metabolism. Eligibility: Adults aged 18 60 without diabetes who have stable weight and can exercise. Design: Participants will be screened with: Medical history Physical exam Heart tests Resting energy expenditure (to determine calorie needs) Blood and urine tests 20-minute stationary bicycle session Food, diet, and mental health questionnaires Participants will stay at NIH for 4 weeks. They will receive 3 meals a day and may eat as little or as much as they want. The diet will change each week. Their weight will be recorded daily. They will ride a stationary bicycle daily. Each week, they will do the following: Spend 1 day in a special room that assesses their metabolism Have 24-hour urine collections Give skin and fecal samples Repeat some screening tests Have scans to measure body fat Complete computerized behavior tasks Wear an activity monitor to track physical activity Wear a glucose monitor. A sensor will be inserted under the skin with a small needle. It will be replaced weekly. Take taste tests. They will swish water and flavored liquids around in their mouth and pick which ones had a non-neutral taste. They will also compare liquids for which ones taste better. Participation will last for 4 weeks. Sponsoring Institution: National Institute of Diabetes and Digestive and Kidney Diseases ...
