Filter by:SCENARIO is a trial to investigate the role of non-drug weight reduction in secondary prevention of stroke. It is a single-blinded, randomized, controlled multicentre trial with two arms. The therapy arm is participating in a comprehensive weight reducing program, whereas the control group takes part in a lecture on healthy nutrition. The primary study objective is to assess the efficacy of non-drug therapeutic weight reduction in the secondary prevention of stroke. Secondary objectives are functional outcome, cognitive status, post stroke depression, and health-related quality of life.
Bariatric surgery of morbid obesity was first located at Førde Central Hospital, but it is now an established treatment at several other hospitals in the health region (Voss Hospital (Helse Bergen), Haugesund Hospital (Helse Fonna) Stavanger University Hospital ((SUS) Helse Stavanger). Surgical methods vary between hospitals: Voss: sleeve gastrectomy, Haugesund: gastric bypass (Roux-en Y),SUS: gastric bypass (Roux-en Y); Førde: biliopancreatic diversion with duodenal switch (BPD / DS) and sleeve gastrectomy . The investigators have then in Helse-Vest a unique opportunity to examine the various clinical and metabolic effects from different surgical methods. This project is part of the regional strategic research initiative in the Helse Vest
Obese individuals that undergo major intervention such as a low-calorie formula diet program or bariatric surgery with the result of substantial weight loss (> 10%) are included and followed-up for at least 3 years. Weight changes and excess weight loss as well as measures of quality of life are monitored. In addition, biomaterials will be collected from these individuals every 6 months for measurement of parameters related to obesity-associated gastrointestinal (GI) impairments such as change in GI hormone levels, change in GI microbiota, or enhanced bacterial translocation. Moreover, micronutrient and metabolomics analysis will be performed. This project allows comparison of non-surgical and surgical intervention and enables to asses the anticipated relationship between obesity and the GI tract in humans in the future.
EFFECT OF HIGH CARBOHYDRATE AND HIGH PROTEIN BREAKFAST ON WEIGHT LOSS, GHRELIN, HUNGER AND CRAVING SCORES IN OBESE MEN AND WOMEN. D Jakubowicz, M Boaz, J Wainstein, O Froy Background: Obesity underlying endocrine, metabolic and eating behaviour features promotes weight gain, increase of hunger, and carbohydrate (Carb) craving. Restrictive diets either in calories or Carb produce withdrawal effect, that further exacerbate Carb craving resulting in rapid return of obesity. Meal timing and composition has shown to play a pivotal role in appetite regulation through several hormonal systems such as ghrelin. The investigators hypothesized that to be successful; a weight loss strategy must change the hormonal environment to increase satiety while reducing hunger and craving. Objectives: To assess weight loss, satiety, hunger, cravings and ghrelin response to two isocaloric diets. Additionally, these outcomes were measured in response to meal challenge. Methods: In this randomized, treatment controlled clinical trial, 146 obese, sedentary adults with impaired glucose tolerance will be assigned to Low carb diet (LCHbd) or an isocaloric diet with a high carb, high protein breakfast (HCPbd),1400 kcal for women and 1600 kcal for men. LCHbd breakfast will provide 300 kcal with carb: protein: fat of 13:40:48. HCPbd breakfast will provide 600 kcal with 50:20:30. From baseline until week 16 participants will take part in a supervised weight loss diet, followed until week 32 by a maintenance period. Anthropometric measures, OGTT for glucose and insulin, VAS-measured hunger and satiety and Food Craving Inventory Analysis will be performed at baseline, week 16 and week 32.
The global epidemic of obesity in childhood continues to evolve and threaten future health and life expectancy primarily due to the increased incidence of cardiovascular disease. Obesity is strongly related to high blood pressure (hypertension) and both conditions pose a risk for target organ damage, which can follow a subject from childhood into adult life. The AORTA study will investigate central hemodynamics and organ damage in 100 obese children and adolescents in order to gain insight to the complex interplay of hypertension, obesity and subclinical damage in order to intensify more precise prevention, thereby reducing the future development of cardiovascular disease.
This study is designed to determine whether obese, normal weight, and successful weight loss maintainers differ in their food choice decision-making and/or executive function, and whether participation in a behavioral weight loss program leads to neural and/or behavioral changes. The investigators will examine behavioral performance on several tasks involving decision-making and self-control in conjunction with brain imaging data acquired during a food-choice decision-making task. Participants enrolled in the behavioral weight loss program will also be assessed following the treatment.
This is an observational study on the efficacy of the secondary placement of the A.M.I Soft Gastric Band in weight regain or weight loss failure after lap. gastric bypass.
The objectives of the present study are: 1. to evaluate if overnight weight loss is dependent on sleep structure assessed by polysomnography; 2. to compare weight loss rate during sleep and awake rest; 3. to compare night weight loss profile of normal and obese volunteers.
This study will determine whether electrical stimulation of an area of the brain called the dorsolateral prefrontal cortex, which is important in determining the feeling of fullness after eating, affects how much food a person eats and weight loss over 4 weeks. It will also compare weight changes in people who attend weight loss counseling sessions and those who do not over this period of time. Obese, non-diabetic people between 18 and 60 years of age who are in good health and who live in the Phoenix, AZ, metropolitan area are eligible for this study. Candidates must have a body mass index of 35 kg/m(2) or more and weigh less than 350 pounds. Participants are admitted to the NIH inpatient unit in Phoenix for the first 9 days of the study for tests, which include meal tests to determine eating behaviors and caloric intake, blood and urine tests, glucose tolerance test, weight measurement, psychological assessments and DEXA scan to measure body fat. For 3 of the days, they will be asked to eat all of their food from automated vending machines. Some subjects receive transcranial direct current stimulation (TDCS). For this procedure, electrodes that conduct electricity are placed on the head and arm and the current is turned on for 40 minutes. Some tingling may be felt under the electrodes. Other subjects receive sham TDCS, with the current turned on only very briefly. After the evaluations, subjects are discharged home from the NIH unit and instructed to eat 25 percent fewer calories than they consumed while on a weight maintenance diet the first 3 days of their inpatient stay. They maintain the lower calorie diet at home for 4 weeks. During this period they come to the NIH unit 3 days a week to receive either real or sham TDCS.
Obesity in children and adolescents is associated with morphologic and functional changes of the vascular wall, suggesting a potential role of juvenile obesity for the development of atherosclerosis later in life. However, no evidence from intervention studies has been provided so far that weight loss in obese children can improve vascular function. Therefore we designed this study including a cohort of obese children before and after a structured weight reduction program in order to answer the question, whether such an intervention can improve vascular function and reverse destructive vascular changes.
