Filter by:The purpose of this study is to examine whether a standardized video education tool will improve knowledge regarding obesity and bariatric surgery and increase bariatric surgery referrals for obese women with endometrial cancer.
The purpose of this study is to Conduct a proof of concept study to assess feasibility, acceptability, and effectiveness of an Metabolic and bariatric surgery (MBS) -supported healthy lifestyle behavioral intervention among adolescent patients, their families, and their clinical team.
This is a prospective, single-center, observational study to explore effects of bariatric surgery on different compositions of trunk fat and mechanisms.
This study randomizes patients to two commonly used peri-procedural antibiotics after gastric bypass with the pre and post-operative collection of stool samples, to identify significant differences in relative abundances of gut microbiota phyla, genera and species between the two antibiotic groups used. Gastric bypass may beneficially affect hypertension by altering the post-operative microbiome and specific antibiotics can further enhance the resolution rate by improving microbial diversity and richness.
This study aims to learn more about how oxalate, a compound found in many foods, may affect a person's chances of forming kidney stones. Active participation in this study will last for around one week. For the first two days, subjects will be asked to eat a special diet at home. From Days 3-5, they will eat special meals delivered to their home from a research clinic at the University of Chicago. They will also collect 24-hour urine samples at home on Days 4 and 5. On Day 6, they will come in to the research clinic at the University of Chicago in Hyde Park, where they will spend most of the day. They will receive a special liquid that contains oxalate, and we will have them eat a specially prepared breakfast that is low in oxalate and citrate.
The purpose of this study is to evaluate the safety and feasibility of the Levita Robotic Platform (LRP) used with the Levita Magnetic Surgical System (MSS)
Visceral pain (VP) following laparoscopic sleeve gastrectomy remains a substantial problem. VP is associated with autonomic symptoms, especially nausea and vomiting, and is unresponsive to traditional pain management algorithms aimed at alleviating somatic (incisional) pain. The present study was performed to evaluate the safety and effectiveness of laparoscopic paragastric autonomic neural blockade (PG-ANB) in managing the symptoms associated with VP following sleeve gastrectomy.
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.
Background: Laparoscopic sleeve gastrectomy (LSG) is one of the commonest bariatric procedures. However, it is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). The investigators' preliminary study suggests that the incidence of postoperative GERD and EE appears to be correlated with the preoperative presence of a lax gastroesophageal flap valve and hiatal hernia. Hypothesis/ Aim: To investigate the impact of a concomitant hiatal hernia repair with LSG on the incidence of postoperative EE. Significance: For patients with pre-existing EE, most surgeons will recommend a laparoscopic Roux-en-Y gastric bypass (LRYGB) as their primary bariatric procedure. However, compared to LSG, LRYGB is a technically more demanding procedure with increased morbidity and long term nutritional deficiencies. For asymptomatic patients at risk of postoperative EE due to presence of a hiatal hernia, there is still no consensus on the most appropriate bariatric surgical option. A LSG with a concomitant hiatal hernia repair, if shown to reduce EE postoperatively, may help to expand the pool of patients suitable for LSG in the future. Methods: A two center, double-blinded, randomized controlled trial of all patients, undergoing LSG with a preoperative diagnosis of a Hill's grade III gastroesophageal junction, will be randomized to having a concomitant hiatal hernia repair (experimental arm) versus just LSG alone (control arm). Primary outcome measures include 1-year postoperative EE on endoscopy. Secondary outcome measures include postoperative morbidity, blood loss, quality of life and GERD symptoms at 1-year postoperatively.
Emerging evidence suggests that dietary and metabolic interventions could potentially target prevention and supportive therapies as well as treatments that may slow the clinical deterioration of neurodegenerative disorders. Though certain dietary patterns can impair specific cognitive domains, e.g., declines in reasoning and global cognition, there is still no consensus on the optimal diet to maintain brain health. Studies have also shown an association between the gut microbiome and neurocognition, as the microbiota can affect neuronal function through neurotransmitters and neuroactive microbial metabolites. Furthermore, studies indicate that diet may strongly influence the gut microbiota. However, the mechanisms for these complex relationships are still poorly understood. Bariatric procedures [i.e., weight loss surgeries] create a unique environment, in which a fast change in gut microbiota composition and dietary patterns occurs through surgery-induced intestinal and metabolic modifications, leading to changes in gut-brain communication. Interestingly, improvements in neurocognitive domains including memory and executive function have been reported post-bariatric surgery. However, there is large variability in these outcomes, indicating that the benefits are not universal. The goal of the current study is to explore the associations between dietary patterns and gut microbiota with cognition and brain structure, using bariatric surgery as an efficient naturalistic experimental design. This project will also explore potential mediators of diet-microbiome alterations as they relate to improvements in brain function and structure. A total of 120 adult patients (> 30y yrs.) scheduled to undergo a first bariatric surgery along with 60 age-, sex-, and BMI-matched waitlist control group will be recruited from the bariatric surgery clinic at the CIUSSS du Nord-de-l'Île-de-Montréal. These individuals will undergo assessments 3 months before surgery, as well as 6- and 12-months post-surgery, or an equivalent time for those on the waitlist. This study will also include 60 age-and sex-matched individuals who are not eligible for bariatric surgery as an additional healthy Canadian comparison group (only one assessment time point). Assessments taken during the data collection period will include: self-report information [e.g., sociodemographic and background information, health and diet behaviours]; information from medical records [e.g., medications usage, peri- and post-surgical complications, etc.]; physiological measures [i.e., blood, urine and fecal samples collection]; cognitive assessment [i.e., neuropsychological tests battery]; and brain imaging [i.e., structural MRI]. Collectively, this study is designed to provide critical information about potential individually targeted diet-based preventative strategies to reduce the development and progression of neurodegenerative disorders. Moreover, this project will explore potential mediators of diet-microbiome alterations as they relate to improvements in brain function and structure, and as such, it will provide essential information on key mechanisms, stimulating further research and the creation of parallel non-dietary therapeutic options.
