Filter by:The goal of this pilot clinical trial is to determine the effectiveness of Tirzepatide in patients with persistent obesity (BMI > 30) 12 months after bariatric surgery (Roux-en-Y Gastric Bypass). We also aim to determine the frequency of side effects with Tirzepatide in this patient population. Patients who take tirzepatide 12 months after bariatric surgery will be compared to patients who receive a placebo.
Opioid-free anesthesia is a new approach to anesthesia, described and used for many years. If it represents many advantages by reducing the side effects of morphine, its precise place in current practice and in terms of postoperative rehabilitation remains to be determined. Studies are not yet numerous enough to affirm a real benefit. Obese patients are potentially able to benefit from the reduction in the use of morphine during surgery, in terms of quality of postoperative analgesia, side effects (respiratory depression, ileus, somnolence) and early rehabilitation.
Bariatric surgery is the most effective treatment to achieve type 2 Diabetes Mellitus (DM) remission in patients with severe obesity. However, there is little evidence of the effectiveness and pathophysiological mechanisms involved in metabolic improvement after hypoabsortive tecniques such as duodenal switch (DS), single anastomosis duodenal switch (SADI-S) or minigastric bypass (MGB). We have designed a randomized study to compare type 2 diabetes remission after the 3 bariatric procedures in patients with severe obesity (BMI > 45kg/m2) and to study the implication of gastrointestinal hormones, bile acids and gut microbiota in metabolic improvement in each procedure.
Bariatric surgery improves health outcomes with a maximal weight loss on average occurring 1 year after surgery but with dramatic between-subjects variability in weight loss (ranging from 20 to 160% excess weight loss) for reasons that remain to be elucidated. The investigators hypothesize that targeting the 3 months pre-surgery period by a calibrated dietary intervention, with fiber enrichment and biotin, will improve gut microbiota richness and subsequently improve subjects' metabolic health that may optimize post bariatric surgery outcomes. The study is designed as a pilot, comparative, randomized, open-label trial with 4 arms: standard of care, biotin only, fibers only, biotin + fibers.
The goal of this clinical trial is to compare, in a population of severely obese patients, two different kinds of follow-up after discharge from in-hospital rehabilitation programme. The main questions addressed are: - primary outcome: comparing the dropout rate at month 11 of patients followed-up by a telemedicine methodology with that of a traditional outpatient visit follow-up. - secondary outcome: comparing the amount of weight loss at month 11 in patients followed-up by telemedicine with that registered in patients followed-up by traditional outpatient visits. Participants are given a set of instruments (scale, activity tracker, automatic blood pressure monitor, oxymeter, and glucometer) and asked to measure vital parameters following a predetermined schedule for one year. Subjects are asked to engage in regular physical activity and follow the nutritional guidelines received at the moment of discharge from hospital.
Adult obesity is due to an excess of body fat. This corresponds to all the fat in the body (or adipose tissue). It is opposed to the lean mass which corresponds to the weight of muscles, organs and viscera. It is defined from the body mass index (or BMI). BMI is calculated by dividing a person's weight by their height squared. According to these criteria, the prevalence of obesity has reached 17% of the entire adult population in mainland France (ESTENBAN 2015 study). The prevalence figures for obesity in the French overseas departments are higher than in mainland France. The latest epidemiological data available in Martinique and Guadeloupe (KANNARI 2015 study) show that approximately 60% of the adult population is overweight and 25% of the adult population is obese. Obesity is considered a chronic disease that increases the risk of cardiovascular and metabolic complications all the more when patients have a BMI ≥ 35 kg/m2, defining severe obesity. When BMI is equal to or exceeds 40 kg/m2, obesity is said to be "morbid" and the risk of cardiovascular complications increases by about 100% to 400% depending on the type of complications. The risk of mortality increases by 50 to 100% compared to the normal weight population. Obesity and inflammation Adipose tissue accumulates around the abdominal viscera after the fat storage capacity of the subcutaneous territories has been reached. The accumulation of visceral fat is accompanied by a low-grade inflammatory response that is responsible for the secretion of lipid derivatives and mediators toxic to the cardiovascular system and insulin sensitivity. The inflammatory response is characterized by the expression of numerous pro-inflammatory molecules synthesized by adipocytes and immunocompetent single-macrophage cells infiltrating the vascular stroma of adipose tissue. In addition, hyperglycemia and excess lipid intermediates cause the assembly of inflammasomes in the cytosol. Among them, the NLRP3 inflammasome involved in multiple human inflammatory pathologies. Inflammation opposes weight loss, hence the need to reduce the inflammatory response to facilitate weight loss in obese people. Pigeon pea, known for its anti-inflammatory properties, is a legume found in Creole gardens and traditionally eaten at Christmas. The OBESICA study aims at studying the interest of consuming pigeon pea associated with regular physical activity on the inflammatory state of the body and weight loss in obese patients.
Prevalence of Obesity and its association with Diabetes Mellitus 2 (DM2) affect a significant percentage of the world's population with great socioeconomic impact, especially for developing countries. Several procedures and interventions are used in its treatment, and the most efficient and with a positive impact on the life of patients with severe obesity and DM2 is Bariatric Surgery. The objective of is analyze the activity of L cells according to the extension of the bilio-pancreatic loop in T2DM patients undergoing GDYR. This study 20 adults of both sexes, above 18 years,before and 6 moths after surgery baritric metabolic, randomized the bilio-pancreatic loop in a proportion of 1:1. Keywords: Roux-en-Y gastroplasty, Immunohistochemistry, L cell, GLP-1, type 2 diabetes.
Obesity has been considered as a risk factor for mortality and development of complications during infection with the influenza virus. Several case studies of severe and fatal infections have identified possible effects of obesity on disease progression; these effects include extensive viral replication in the deep lung, progression to viral pneumonia, and prolonged and increased viral shedding. These points may be linked to obesity which causes a chronic state of meta-inflammation with systemic implications for immunity: obese patients exhibit delayed and blunted innate and adaptive immune responses to influenza virus infection, and they experience poor recovery from the disease leading to an increased susceptibility to secondary bacterial infections and poor healing of the lung epithelium. Furthermore, in obese people, influenza virus may exploit the lack of antiviral pressure, generate a more virulent population and increase disease severity Due to the growing prevalence of obesity worldwide (500 million subjects in 2017), it is important to be able to offer vaccines that provide the highest protection for this at-risk population. The quadrivalent recombinant high-dose influenza vaccine has been shown to have greater immunogenicity and efficacy than standard influenza vaccine in non-obese adults older than 50 years. However, this vaccine has never been evaluated in obese subjects. Investigators thus planned this trial to assess whether the use of the new quadrivalent recombinant high-dose influenza vaccine (RIV4) will induce a better immunological answer than current quadrivalent standard vaccine (SD) in patients with severe obesity, with an acceptable safety profile, thus leading to a better protection against influenza in this population at high risk of influenza complications.
A high prevalence of psychological trauma on one hand and of psychiatric disorders, such as depression, anxiety, suicide attempts, addictions, and eating disorders on the other hand, has been reported in patients with severe obesity seeking bariatric surgery. Some studies reported an increased prevalence of these psychiatric disorders after bariatric surgery, potentially related to weight regain. In this context, psychological resilience is a concept that brings together internal and external factors of adaptation, and whose clinical use facilitates interdisciplinary collaborative work. This research focuses on the association between resilience and success or failure of bariatric surgery in patients followed in the Specialized Obesity Center (CSO) of the Nancy University Hospital. The hypothesis is that psychological resilience before surgery promotes successful surgical treatment. This retrospective study is based on existing data from patients with severe obesity who have undergone bariatric surgery at the Nancy CSO. The main objective is to study 1) the resilience of patients with severe obesity, candidates for bariatric surgery, at the first assessment (T0), at the end of lifestyle/behavioral modifications program (T1) and at 2 years after bariatric surgery (T2), 2) the relationship between internal and external factors explaining resilience and final weight outcomes. The investigators are expected that non-resilient patients have more psychological vulnerabilities (psychopathology, negative life events, etc.), and have lower weight loss than resilient patients.
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. Sleeve Gastrectomy (SG) has become the most performed intervention either worldwide or in France, where SG represents more than 60% of bariatric interventions and 114,817 patients operated between 2013 and 2016. Maximum Excess weight loss (%EWL) after SG is obtained at one-year post surgery. Then it has been largely reported in the literature that patients could present mild, moderate or important (notably in the super obese patients) weight regain associated with comorbidity relapse motivating redo surgery. Like in revisional surgery, operating super-obese patient (BMI ≥50 kg/m2) is a challenge. It has been shown that achieving significant weight loss was more difficult in patients with a BMI ≥ 50 compared to lower BMIs.
