Filter by:This double-blinded proof-of-concept study is proposed to explore the effects of fecal microbiota transfer (FMT) in human subjects. Here we perform FMTs into obese recipients using stool from lean unoperated donors and from previously obese patients after successfull treatment with bariatric Roux-en-Y Gastric Bypass (RYGB) surgery. Obese patients treated with their own material (autologous FMT) serve as controls. After FMT treatment the functional impact of post-surgery microbiome changes on host energy consumption and regulation of blood glucose levels will be analysed. Additionally the variations on the microbiota and metabolite composition will be profiled using extensive sequencing analyses. The major aim of the study is to explore the scientific rationale for targeted gut microbiota modulation in management of obesity and related metabolic diseases.We estimate the transfer of microbiota from RYGB donors is superior to the transfer of lean microbiota at inducing reduced adiposity and improving high blood glucose levels in obese recipients. Each is better than a sham procedure (autologous FMT), which itself can also induce considerable short-term effects.
The goal of this clinical trial is to perform a detailed description of the feno- and genotype of people living with type 2 diabetes and severe obesity who are linked to care at Steno Diabetes Center Greenland. The main questions it aims to answer are: - Are monogenetic diabetes variants associated with the same risk of developing late diabetic complications as other types of diabetes? - Can genotyping and thereby personalized medicine be implemented in Greenland, and can personalized medicine lead to improved treatment? - What is the prevalence of sleep apnea among high-risk individuals in Greenland? - Is it possible to develop and implement a simple algorithm for the identification of sleep apnea in Greenland that can ensure treatment of severe sleep apnea? Participants will: - Answer WHO-5 and FOSQ-10 questionnaires regarding quality of life and functional outcomes of sleepiness - Perform VAGUS examinations for Cardiovasculare Autonomic Neuropathy - Clinical examination of height, weight, circumference of hip, waist and neck, Friedman tonsil and tongue score, nasal air flow, nasal septal deviation - Blood samples for full genome sequencing
The aim of this observational study is to explore and describe changes in cardiometabolic health, physical activity, physical capacity, and wellbeing during interdisciplinary Semaglutide-based weight loss treatment in patients with severe obesity and multimorbidity. This study is explorative and therefore does not include hypothesis testing.
In the stomach, the ghrelin-containing cells are more abundant in the fundus than in the pylorus originally termed X/A-like cells. These X/A-like cells account for approximately 20 % of the endocrine cell population in adult oxyntic glands. Ghrelin enhances the secretion of growth hormone, the stimulation of appetite and food intake, the modulation of gastric acid secretion & motility and the endocrine and exocrine pancreatic secretions.
Obesity is a complex chronic disease, in which both genetic and environmental factors are involved, that shows a great heterogeneity in the response to different weight loss programs. Identifying patients as responder or no responder to the different obesity treatment options is a concept of great interest, both due to the high prevalence of obesity and its high consumption of resources. More than 500,000 surgeries are performed every year around the world, of which approximately 30% will present unsatisfactory results. The general objective is to carry out a multi-omics approach for the discovery and validation of markers of weight response to bariatric surgery (BS) in a large sample of people with severe obesity (n=6,966 men and women who underwent sleeve gastrectomy or gastric bypass, including an additional external validation set). Thus, the investigators want to know the integrated contribution of several genomic markers (Genome Wide Association study, GWAs), new clinical and analytical variables (human exposome concept) and gender perspective to the prediction of response to the intervention at 12 month and its long-term longitudinal maintenance (3 years). The investigators intend, therefore, to provide new evidence to advance towards precision medicine. The investigators will focus our attention also on identifying those patients who, after being classified at the weight loss nadir as responders experienced weight regain.
Two types of face masks : cuffed and uncuffed were evaluated for artificial ventilation in obese patients. After induction to anesthesia patients were ventilated with both types of masks using anesthesia machine with the same settings: Tital Volume of 500 ml, respiratory rate of 12/min. The inspired and expired volume was measured using anesthesia machine volumeter, The difference between inspired and expired volume was counted. The comparison between two types of masks was performed taking into consideration several parameters: type of obesity, gender, age.
Laparoscopic bariatric surgery are becoming the most used procedure to treat the obesity. To facilitate safe initial access to the abdominal cavity, we insert an optical viewing trocar at the left hypocondrium. The aim of this study is to systematically evaluate all published data existing in the literature to analyze the safety of optical trocars in patients undergoing bariatric surgery and to compare these data with our experiences.
Severe obesity is associated with considerable reduction of wellbeing and life expectancy. People living with severe obesity tend to die 8 to 10 years earlier. Preoperative management of patients living with severe obesity can be challenging and proper weight-loss may help obtain better outcomes and less morbidity. The effectiveness of GLP-1 analogue Liraglutide in preoperative weight-loss was evaluated in the study.
This study plans to learn if the EvoEndo Endoscopy system can be used to evaluate, provide and follow up care for upper gastrointestinal tract diseases in the bariatric population. The smallest current scope available for such a technique is an adult transnasal endoscope with a larger diameter, a pulmonary bronchoscope or Ear Nose and Throat (ENT) laryngoscope. This study is evaluating a newly Food and Drug Administration (FDA) cleared ultra-slim, single-use, endoscope specifically designed for transnasal endoscopy to evaluate its use in adult upper tract gastrointestinal diseases. If such a technique is successful it could improve the safety, cost, and access of endoscopic care for patients in need of an endoscopic evaluation for a bariatric medical condition.
The objectives of this study are to assess the initial safety and device functionality of the SFM Anastomosis System including delivery systems when used to create a duodenal-ileal (D-I) anastomosis with patients with prior sleeve gastrectomy who experience inadequate weight loss (i.e., SNAP-PS procedure). Additionally, the study is designed to evaluate the potential of the SFM Anastomosis System to create a Jejuno-jejunostomy in Roux-en-Y gastric bypass procedures.
