The overall purpose of this project is to study the acute, short- (≤ 1 year) and long- (> 1 year) term effects on body composition and psychological health after a 10 to 14-weeks comprehensive lifestyle modification program for the treatment of severe obesity. The aims of the PhD project are to investigate whether an intensive lifestyle intervention leads to acute and short term (< 1 year) changes in: 1. The BMI/Weight 2. Body composition (waist circumference, fat mass, fat free mass, skeletal muscle mass and visceral fat area) 3. Psychosocial factors such as eating behavior, anxiety and depression symptoms and health-related quality of life
Randomized clinical trial of two preoperative diets before bariatric surgery (gastric bypass)comparing standard diet and Prodimed (VLCD) in 100 morbidly obese patients selected for a gastric bypass procedure
This is a randomized clinical trial assessing the outcome of two surgical strategies to treat severe obesity; laparoscopic gastric bypass and laparoscopic VBG. Main outcome is weight loss and weight loss maintenance but other factors as body composition, eating pattern, metabolic normalisation, energy expenditure will also be assessed.
Postoperative residual curarization in the post anaesthesia unit has been associated to complications involving respiratory function and impaired laryngeal and pharyngeal muscles' function. Speed of reversal of neuromuscular blockade after administration of sugammadex versus neostigmine has been studied, but up to date no data are available concerning continuous acceleromyography monitoring of adductor pollicis and corrugator supercilii in morbidly obese patients undergoing weight loss surgery. The investigators' aim in this prospective, double-blinded study was to compare train of four ( TOF ) values, the presence or absence of clinical criteria of postoperative residual curarization , the dose requirements and the side effects of sugammadex and neostigmine for the reversal of rocuronium induced neuromuscular blockade in patients undergoing laparoscopic or open surgery for morbid obesity.
This study is to determine if the Lap-band system is safe and effective for use in morbidly obese adolescents.
Laparoscopic Sleeve Gastrectomy has emerged over the last 20 years as a treatment of choice in the surgical management of patients with morbid obesity. However, this restrictive procedure is accompanied by outcomes such as gastric fistula (5%), postoperative hemorrhage (1%) and intra-abdominal loco regional collections (1%). At present, there is no sufficiently reliable technique to prevent these complications.
This study aimed to measure, compare apelin, resistin, visfatin levels in patients underwent to RYGBP, LAGB and their relation with obesity.
Purpose is to determine the effect of ephedrine and caffeine, on metabolic rate and weight loss after bariatric surgery. Approximately 40% of patients struggle with their weight loss rate, or metabolic rate, after bariatric surgery, and at least 30% previously had or develop a low metabolic rate after surgery. Metabolic rate is the speed at which calories are burned. The fewer the calories eaten and the more calories burned, the more rapidly weight is lost. It is possible that despite a very low calorie intake following bariatric surgery metabolic rate will decrease so much so that weight does not decrease even if intake is reduced to 1000 calories per day. Ephedrine is a medicine used commonly to treat asthma, difficulty breathing, and wheezing. However, 40 years ago it was reported in scientific studies that ephedrine increases weight loss in patients on low calorie diets by increase the amount of calories that are burned. Combining caffeine with ephedrine makes ephedrine work more efficiently (more weight loss over time). Many studies show the effect of ephedrine on weight loss that began in 1974 with patients on food diets. Ephedrine used in various strengths and with a number of different combinations has shown to be effective and safe, especially when directed by a physician. There is only one study where ephedrine has been used in patients after bariatric surgery. In that study, both the patient and medical staff knew they were taking ephedrine (i.e., they were not "blinded"). The patients who were not losing weight or had measured low metabolic rates were treated with ephedrine. The patients taking ephedrine lost more weight after surgery than those not taking ephedrine. While this is a significant finding, the study was not designed to be the best test of the effects of ephedrine. The best test is where neither the patients nor the medical staff know if the patient is taking the active drug (double blind). All patients enrolled into the Research Study will receive capsules that contain either ephedrine and caffeine (the active drug) or identical capsules with no active ingredient (called a "placebo"). Neither group of patients will know which set of capsules they receive. The expected duration of treatment in the Study is 7 months from the day of surgery. This is a single site study. All patients will have their gastric bypass performed through Oregon Weight Loss Surgery at Legacy Good Samaritan Hospital. The investigators expect to study 200 patients with 100 receiving the study drugs (ephedrine and caffeine in a capsule) and 100 receiving placebo (inactive ingredients in an identical capsule) over approximately 6 months.
This study will determine how morbid obesity affects the distribution and metabolism of the drug propofol. The investigators hypothesize that propofol will be distributed and metabolized differently in morbidly obese subjects as compared to normal weight subjects.
