Filter by:Exercise is a vital part of cardiopulmonary conditioning, this means improving general fitness. Undertaking surgery has been likened, physiologically, to running a marathon. It is essential that before any operation the patient undergoing the procedure is as optimised as possible. Bariatric surgery is no exception. Patients with a high weight often have other conditions most commonly related to the heart and lungs through the excess visceral fat content. This places this group of patients at particular risk of potentially, albeit rare, of having a major and possibly catastrophic cardiac event on the operating table during anaesthetic. Pre-operative conditioning is therefore vital in this group of patients who are often young and not other than their weight necessarily unwell. Exercise plays an important role in the run up to surgery however, many pre-operative exercise prescription programs in the past have failed, often related to the lack of compliance. However, this maybe due to the poor body image they have of themselves presenting in public to the gym or swimming pool. Current Virtual Reality Games propose that, through their use they encourage exercise and increase heart rate. Given the more personalised nature of this form of media over public engagement, this new media may offer an opportunity to explore whether there is any benefit in terms of pre-conditioning this group of patients prior to their surgery. This study aims, in its first instance, to evaluate whether the Virtual Reality promoted exercise games encourage and can sustain increased activity prior to surgery.
Overweight and obesity are worldwide health problems that can affect negatively quality of life. With increasing prevalence of obesity and the failure of compliance to lifestyle, bariatric surgeries have become the treatment of choice to help achieve long term sustainable weight loss. In some cases of bariatric surgery, weight loss stops and there are cases in which obesity manifests itself again; the mechanism underlying the re-appearance of obesity is not known. Recently, the gut microbiota, has been implicated in the etiology of obesity and metabolic syndrome due to its important role in digestion, metabolism and regulating gut peptides and hormones. In accordance with this, it has been shown in mice that obesity can be associated with dysbiosis (Imbalance in gut bacteria) and there has been successful reduction of weight in interventions when microbiota was manipulated. Hypothesis: 1. Emirati participants will have unique microbiota and gut peptides when compared to Lebanese participants. 2. The microbiota and gut peptides variability is significantly different between those with normal weight compared to obese participants undergoing bariatric surgery. 3. The bariatric procedure will have a significant effect on the variability of microbiota, gut peptides, blood chemistry, dietary intake and metabolism among the obese participants. Objectives of the study: 1. Determine the gut microbiota composition of Emirati healthy normal weight participants and compare to that of Lebanese via Illumina sequencing NGS (Next Generation Sequencing of the 16S rRNA gene) of the microbiota from the stool samples. 2. Determine the gut microbiota composition of Emirati obese participants and compare to that of Lebanese counterparts using NGS. 3. Determine the effect of bariatric procedure in UAE and Lebanon respectively on gut microbiota (using NGS), gut peptides in plasma, blood chemistry and metabolism using indirect calorimetry and food intake. Importance of this research: The microbiota and gut peptides variability is determined by body weight and ethnicity of the studied populations. It is hypothesized that bariatric surgery will have a significant effect on the variability of microbiota, gut peptides, blood chemistry, dietary intake and metabolism. This study will be a pioneering research in UAE and Lebanon to assist in finding population tailored therapeutic strategies that target the gut microbiota and treat obesity.
Compare the level of PA (physical activity) in groups with and without STIMUL device at 4 months
The aim of this study is to investigate the body awareness and the factors affecting the bariatric surgery.
This is a prospective cohort study which aims to explore the effect of bariatric surgery on cardiac and vascular structure and function in obesity. Enrolled patients will receive the following examinations before surgery and 3,6,12 month after the bariatric surgery: 24-h central and brachial ambulatory blood pressure monitoring, PWV, echocardiography, vascular endothelial function, hemodynamic including cardiac output and peripheral vascular resistance and so on. We compare these data before and after surgery in order to evaluate effectiveness of bariatric surgery in the cardiac and vascular structure and function.
The weight reduction obtained after a first bariatric surgery would improve the vascular (correction of endothelial dysfunction, improvement of arterial wall compliance and evolution of the atherothrombotic process) and microcirculatory function in obese patients with type-2 diabetes.
Obesity prevalence rapidly increased in the past decades in French population with multiple health consequences responsible for excess mortality. In the same period of time, the number of bariatric procedures have developed exponentially. Despite its great efficacy on weight loss but also on resolution of comorbidities, bariatric surgery is not without risks. Our hypothesis is that a better understanding of the physio-pathological consequences of obesity and bariatric surgery, notably on the gastrointestinal tract, may allow to improve the treatment of obesity and to find alternatives to bariatric surgery. The main objective of this cohort study is to systematize the collection and the conservation of biological samples (blood, stomach, liver, intestine, adipose tissue) obtained during bariatric surgery, in obese subjects undergoing surgery (including sleeve gastrectomy, Roux-en-Y gastric bypass, or revisional intervention for complication or weight regain) in the University Hospital group of Paris Nord Val de Seine (HYPNVS). The main projects that will build on this cohort will cover the physiopathology of obesity and its consequences, notably in the field of gastrointestinal tract including: modification of gastro-intestinal plasticity in severe obesity and after bariatric surgery and alterations of absorption of nutriments (lipids, proteins, carbohydrates) induced by obesity and bariatric surgery. The inclusion in this project of obese subjects before surgery, or lean or obese subjects after surgery will allow to distinguish the impact of weight loss and surgery on gastrointestinal remodeling. This cohort will also allow to characterize stomach and intestinal proteome in severe obesity and to precise the influence of tissue inflammation on metabolic disorders associated with obesity.
Prospective association study to analyse patients' outcome after bariatric surgery. Outcome comprises postoperative pain, analgesia, postoperative side-effects, long-lasting pain, patients' impairment in daily living.
The therapeutic problem of obesity is weight control, a major difficulty, involving a significant change in eating behavior. A number of studies show that there are many factors of resistance to weight loss whether they are physiological, genetic, environmental pressure related, or psychological and behavioral. For some patients, the surgical approach seems the best alternative. Indeed, bariatric surgery is an effective therapeutic weapon in patients with morbid obesity. However, it has been shown that approximately 25% of patients are failing at two years of this surgery (Reinhold's index). Some of the failed subjects may benefit from surgical revision. As for the others, no intervention is currently proposed to them. Studies have shown that the psychological profile of patients who are candidates for bariatric surgery is predominantly impulsive, very anxious with a tendency to depression. The stress level of these patients would be important, and they would have low self-esteem. This study hypothesize that, in these patients, the establishment of hypnotherapeutic management associated with the usual dietary monitoring could modify eating habits thus promoting weight loss and an improvement in self-esteem , stress and anxiety compared to dietary monitoring alone.
The purpose of the study is to test how dietary habit interventions affect patients weight loss outcomes after bariatric surgery.
