Active clinical trials for "Obesity, Morbid"

The investigators seek to analyze the samples provided by patients with obesity-associated fatty liver disease at the multi-omics level and to integrate the results with clinical information, genotypic variants, and factors influencing inter-organ crosstalk. The main aim is to improve the interpretation of fatty liver disease associated with obesity and diabetes by developing predictive models built with algorithms from artificial intelligence. The challenge is to decipher the flow of information by exploring contributing factors, proximate causes of regulatory defects, and maladaptive responses that may promote therapeutic approaches.

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.

Changes to gastric pH, gastric emptying time, gastrointestinal transit-time or the pre-systemic metabolizing effect of enzymes secreted in the mucosa may all alter the pharmacokinetics of medicines. These factors are potentially influenced by bariatric surgery. Little is so far known about how gastric bypass and sleeve gastrectomy impacts the biological availability of medication. In this study the pharmacokinetic effects of bariatric surgery on paracetamol are investigated.

Obesity bariatric surgery patients usually lose more than 50% of their former obesity within a relatively short time (~ 2 years). There is still a lack of knowledge about underlying psychological and biological mechanisms of decline in body weight. The intention of this project is to investigate whether bariatric surgery is associated with patients' cognitive ability, lifestyle and/or gene expression and metabolomics.

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.
