The aim of the current study was to explore the effect of a 6-months motivational physical activity intervention (MPAI) on different psychosocial variables (e.g. motivation, health-related quality of life, self-esteem, etc.) and on the physical activity levels of bariatric surgery patients. Comparing with a control group (CG), we tested the differences obtained on these variables between before surgery and just after the MPAI (7-months after surgery). Additionally, we explored the (possible) prolonged effects of the intervention by doing re-tests 13, 25 and 37- months after surgery.
Along with the technological advances in medicine, videolaryngoscope is the most commonly preferred technique for intubation of expected difficult airway management such as morbidly obese patients. In this prospective controlled clinical study, the purpose is to compare C-MAC videolaryngoscope and McGrath videolaryngoscope in respect to duration of intubation, haemodynamic response, and complications related intubation of morbidly obese patients undergoing bariatric surgery.
This prospective, open-label, randomized-controlled trial is designed to evaluate the use of the Traxi panniculus retractor-- a commercially available Class I FDA-exempt device will improve surgical outcomes, cardiopulmonary function, and provider/patient satisfaction in morbidly obese women undergoing cesarean delivery.
This is an open-label, phase I pilot trial designed to evaluate the safety and feasibility of deep brain stimulation (DBS) for the treatment of refractory morbid obesity. Patients with diagnoses of morbid obesity will be recruited and enrolled. All patients will receive DBS targeting two brains areas involved in the pathophysiology of obesity and will be followed post-operatively for 12 months.
The purpose of this study is to examine the feasibility, acceptability, and preliminary efficacy for the inclusion of support figures and romantic partners throughout the bariatric surgery process, from pre-surgery to two months post-surgery. This will be done using a four-arm randomized controlled trial (RCT). Using simple randomization, female patients in romantic relationships will be randomized into partner attended (PA) groups and treatment as usual (PA-TU) groups; patients (female or male) not in romantic relationships will be randomized into support figure attended (SFA) and SFA-TU groups. The goals of this study are to provide preliminary evidence for including support figures/partners in patients' routine BS healthcare visits, including the subsequent impact on post-surgery patient and support figure/partner behavior change and weight loss, relationship outcomes, and exploration of barriers to support figure/partner involvement. Aim 1: To assess the feasibility and acceptability of support figure/partner involvement for BS patients. Feasibility will be assessed throughout the study by attendance at the four pre-surgery classes and the clinic visit assessment time points. Perceived fiscal and time involved in the study will be assessed. Acceptability will be assessed from patient and support figure/partner interviews regarding the barriers and benefits to attendance, and alternative mediums to engage support figures/partners. Aim 2: To evaluate the effect of support figure/partner attendance (SFA, PA arms) on patient weight loss, behavior change, and relationship outcomes from T1-T4. Estimates of effect size and variance in patient weight loss and behavior change will be collected from T1-T4 for comparison of the SFA/PA and SFA-TU/PA-TU arms.
Whether greater weight loss is as a result of a smaller reduction in energy expenditure with caloric restriction is not known. Resting energy expenditure and 24-hour energy expenditure vary substantially between individuals. In some cases, relatively reduced rates of 24h EE predict weight gain in some populations who have high prevalence of obesity. Obese individuals that lose weight experience a decrease in 24-h EE and resting energy expenditure that is lower than predicted based on changes in body composition. Most weight loss studies have found a large individual variation in the amount of weight change, and whether an individual's response to an intervention can be predicted is not clear. Measurements of 24-hour EE in response to fasting may help predict weight loss. The ECAL indirect calorimeter (ECAL) is a validated device purpose-built to provide the practitioner and patient with energy information that allows for more accurate, reliable method of establishing an obese individuals' metabolic profile. The aim of this study is to determine whether providing energy information from ECAL indirect calorimeter as an adjunct to the multicomponent weight management intervention in non-diabetic obese and severely obese individuals would help predict the response of weight loss.
Rapid metabolic improvements seen with sleeve gastrectomy are likely a result of changes in gastric origin. The gastric mucosa is an endocrine organ that regulates satiation pathways and is a complex regulator of food intake as well as lipid and glucose metabolism. This study aims to assess the efficacy and safety of endoscopic selective gastric mucosal devitalization (GMD) for the management of obesity and its related comorbidities.
Complications associated with excess weight (hypertension, coronary artery disease and diabetes) have become major causes of morbidity and mortality after liver transplantation (LT). To ensure excellent long-term outcomes with LT it is critically important to understand the best strategies to minimize obesity and its associated complications in our patients. Weight loss can be achieved through dieting and exercise, but most patients are unable to maintain the weight loss. In the general population, bariatric surgery is much more effective than medical treatment for permanent weight loss and prevention or reduction of obesity-associated complications. The purpose of this study is to determine the safety and effectiveness of performing sleeve gastrectomy (SG) procedure in the early post-LT period in obese patients. The patient population for this study will be anyone listed for liver transplantation at Toronto General Hospital (University Health Network, Toronto, ON, Canada) and meeting the current standard criteria for bariatric surgery (BMI>40, or BMI>35 with at least 1 obesity-related complication).This study will randomly assign eligible participants to one of two groups (1:1). Patients in group 1 will receive standard lifestyle/diet counselling while patients in group 2 will undergo SG-specific counselling prior to transplant and the SG procedure within 2 weeks of LT (if safe to do so). All participants will be followed for 12 months.
Obesity is a major public health problem worldwide. Bariatric surgery has proved to be the most effective treatment of morbid obesity in terms of weight reduction and remission of co-morbid conditions during long-term follow-up. Nowadays, France is ranked 3rd in terms of bariatric surgeries performed per year. Since the laparoscopic Roux-en-Y gastric bypass (RYGB) was described in 1977, this restrictive and malabsorptive procedure has become a gold standard for morbid obesity with an average Excess Weight Loss % (EWL%) of 72% at 2 years, and a strong metabolic effect, especially with regard to type 2 diabetes remission. Nevertheless, failures are observed (up to 20%), particularly in super obese patients, which are then difficult to manage. In this population, biliopancreatic diversion with duodenal switch (BPD-DS) is indicated due to its stronger weight loss and metabolic effect, but is still little performed worldwide because of its higher morbidity, surgical complexity and risk of malnutrition. A novel technique combining the physiological advantages of pylorus preservation and the technical benefits of single-loop reconstruction was introduced in 2007 by Sanchez-Pernaute, who described the single-anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) as an evolution of the BPD-DS. With a 2.5-meter common channel, SADI-S seems to offer good results for the treatment of both morbid obesity and its metabolic complications, with an EWL% of up to 95% at 2 years and potentially less nutritional consequences. To date, there is only one Spanish randomized trial comparing SADI-S to BPD-DS, whereas BPD-DS represents less than 1% of bariatric procedures in France and is only allowed in super obese patients. Thus only preliminary data of poor scientific value exists. Nevertheless, facing very encouraging short-term outcomes, there is a real need for a prospective trial comparing SADI-S to a standard bariatric procedure. The aim of the investigator's study is to assess weight loss efficiency and the morbi-mortality of the SADI-S in comparison to a standard (RYGB), in order to validate this procedure among bariatric techniques HYPOTHESIS SADI-S is superior to the standard RYGB for weight loss, increasing the EWL% by 10% (82% vs 72%, respectively) at 2 years.
The purpose of this study is to assess the safety profile of bariatric embolizations and confirm published reports of sustained post-procedural weight loss, and pathologically assess post-procedural metabolic effects.
