Filter by:This research program aims to comprehensively investigate the clinical, physiological, metabolic, and molecular effects of reducing sedentary behavior in post-bariatric patients. To this aim, we will conduct a crossover trial and a randomized controlled trial. The crossover trial aims to unravel potential mechanisms underlying the metabolic, physiological and molecular effects of breaking up sedentary time with light-intensity physical activity versus carrying out the minimum amount of daily exercise at once and then remaining sedentary versus simply remaining sedentary throughout all sessions, in a well-controlled laboratorial condition. The 4-month parallel-group randomized controlled trials aim to investigate the feasibility and efficacy of a newly developed personalized intervention focused on replacing sedentary time with light- (or very light-) intensity physical activity in these patients. A multitude of gold-standard techniques will be applied to evaluate the effects of the intervention on several outcomes, including sedentary time (primary outcome), physical activity levels, clinical parameters specific to each condition, cardiometabolic risk factors, immune function, and health-related quality of life.
Background: Patients awaiting bariatric surgery, apart from suffering higher BMI, show a large number of comorbidities and a low physical fitness. These factors are associated with a longer surgery time, a longer hospital stay and a greater number of operative complications. To reduce these disadvantages, a nutritional intervention is performed to reduce total weight and the comorbidities associated with obesity prior to surgery. However, the prescription of an exercise program, which can be an effective tool to improve these factors, is not usually part of the usual care of these patients. Objective: To know the effects of a semi-supervised exercise program on body composition, cardiovascular risk factors and operative complications in bariatric patients. Methods: Approximately 3 months before surgery, 60 patients awaiting bariatric surgery will be recruited. Patients will be randomized into two groups: a) an experimental group (n = 30); b) a control group (n = 30). The experimental group will perform a semi-supervised exercise program, while the control group will only perform the corresponding evaluations. Both groups will be assessed for body composition, cardiovascular risk factors, physical condition, quality of life and physical activity levels at the beginning and at the end of the intervention. In addition, surgery time, hospital length of stay and operative complications will be evaluated in both groups.
The primary objective is to measure the impact of this treatment for patients with obesity of class I, or class II without co-morbidity, assessed by excess weight loss (EWL)>25%. The secondary objectives are to measure total body weight loss >5%, BMI reduction, tolerance, complications related to this technique in this indication. This study is a prospective, pilot, bi-center safety and efficacy study. 30 patients will be enrolled between APHM, Marseille et CHU L'Archet Nice
This study aims to evaluate the use of deep neuromuscular blockade and low-pressure pneumoperitoneum in bariatric surgery. The investigators propose to conduct a double-blind randomized controlled trial (RCT) comparing deep neuromuscular blockade versus standard blockade, and its impact on operative conditions during bariatric surgery. This trial will be conducted at one of the highest volume bariatric centers in Canada. This study also aims to examine the effects of deep neuromuscular blockade on patient-relevant outcomes, including postoperative pain and narcotic use. The investigators anticipate this study will facilitate the continual improvement of care provided to a growing number of bariatric patients.
Obesity has become a significant health problem in Canada. When conservative efforts to lose weight fail, bariatric surgical procedures are often considered. Today, the most common bariatric procedures in North America are Laparoscopic Roux-en-Y gastric bypass (LRYGB) and Laparoscopic Sleeve Gastrectomy (LSG). For many reasons, an initial bariatric procedure may require surgical revision. Some reasons include weight regain, failed weight loss or other acute and chronic complications not related to weight loss. In these cases, it may be indicated that a procedure be reversed inor converted to another type of bariatric procedure. Regardless of the planned intervention, revisional surgery is always more difficult than the initial procedure mainly due to surgical scarring and altered anatomy. Though revisional bariatric surgery has been shown to be safe, our hope is to improve the safety profile by utilizing robotic surgery. Robotic surgery can facilitate more complex procedures by providing superior imaging and freedom of movement during the procedure. The aim of our study is to evaluate prospectively the outcomes of robotic compared to laparoscopic revisional bariatric surgery in terms of perioperative outcomes such as complication rates, operative time and readmissions as well as weight loss/comorbidity resolution (diabetes, hypertension, sleep apnea) where applicable.
Prospective multicenter observational clinical study on a dietary regimen in obese patients scheduled for bariatric surgery.
Nowadays obesity is emerging as a very common health problem. It has been shown in various studies that obesity may be an important risk factor for the onset and progression of knee osteoarthritis (OA). The aim of this study is to determine the effects of bariatric surgery on knee pain, loss of function, quality of life and central sensitization.
To investigate the effects of different fat metabolites on gut hormone secretion in gastric bypass operated subjects and BMI-matched controls.
While bariatric surgery is established as a safe and effective alternative with well-defined risks for severely obese adults, little has been published on its use in children. There are many unresolved questions concerning the long-term metabolic and psychological consequences of bariatric surgery in adolescents, and the difference with the adult population. The appropriate timing for bariatric surgery in young people, and the predictors of success and safety still need to be determined. The aim of this long-term prospective study is therefore to establish the safety and efficacy profile of surgical procedures and to clarify whether reductions in morbidity and mortality outweigh the risks of serious surgical complications and lifelong nutritional deficiencies.
