Gastro-Intestinal Disorder

Currently, ANSM recommendations govern FMT (Fecal Microbiota Transplantation) in clinical trials. The collection and validation of these stool donations as part of the trials is complex and not very efficient. It therefore seems essential to identify the limiting factors and the characteristics of Healthy Volunteer Donors to optimize the number of valid stool donations.

The study participant is being asked to take part in this clinical trial, a type of research study, because the participant has Gastrointestinal (GI) symptoms following a Hematopoietic Cell Transplant (HCT). Primary Objective * To determine the safety and feasibility of FMT for treating a GvHD of the gut following HCT. * To determine the safety and feasibility of FMT for treating HCT induced gut dysfunction. Secondary Objectives * To assess the potential efficacy of FMT for treating a GvHD of the gut following HCT. * To assess the potential efficacy of FMT for treating HCT induced gut dysfunction.

The goal of this observational study is to learn about the comparisons of inflammatory markers between IBD and non-IBD (control) participants. The main question it aims to answer is: Are there differences in inflammatory markers between IBD and non-IBD (control) participants.

Some reports cite over 80% of surgery residency graduates are seeking additional training to improve on their experiences to be ready for practice. The Fellowship Council created several fellowship tracts including HPB (Hepato-Pancreato-Biliary),Advanced GI (gastrointestinal) and Minimally Invasive surgery to address this issue, and bridge the gap in training between residency and real life practice in those that seek a practice in HPB or complex GI surgery, respectively. By the end of fellowship, the core goal is to make the graduating fellows ready for independent practice in HPB or complex GI surgery cases.

The aim of this anonymous survey is to identify who teaches GI procedures to general surgical residents during residency training and understand the need as well as desire for an Advanced Surgical GI fellowship amongst senior surgical residents. We also hope to identify the self-reported level of comfort of senior general surgery residents in completing both common and complex GI procedures.

The Gastroparesis Registry 4 (GpR4) is an observational study of patients with symptoms of gastroparesis (Gp) and functional dyspepsia (FD) with either delayed or normal gastric emptying. To better understand these disorders, this registry will capture demographic, clinical, physiological, questionnaire, and patient outcome data to characterize the patients and their clinical course. Participants will complete several questionnaires, complete a nutrient drink test and have a gastric emptying study.

The risk of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP) is influenced by patient and procedure-related factors. Strategies to decrease PEP(Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis) are of great importance.

Colonoscopy which is the standard examination for the exploration of the colon and rectum is performed very frequently. Colon preparation before the examination is an essential step and pescription of the colonic preparation is carried out by the gastroenterologist. However, despite a standardized explanation of the colon preparation, there is heterogeneity in understanding the colonic preparation, which in some cases compromises the quality of the colonoscopy examination. This clinical study aims to investigate whether an explanation of colonic preparation by tutorial films would increase the quality of colon preparation and would reach the recommendations of the Société française d'endoscopie digestive (SFED) in 2019.

Adult patients after elective major abdominal surgeries who are planned to be admitted to the Intensive Care Unit (ICU) can be included in the trial. Each patient will be fed via the gastrointestinal tract. Half of the patients will receive enteral nutrition (EN) with additional fluids, and the rest will receive undiluted EN. The primary aim of this study is to assess feeding intolerance in both patient groups.

The goal of this single-centre observational study conducted at the Royal Hospital for Children in Glasgow, Scotland, is to employ a multi-omics approach to investigate the "gut-lung axis" in health and disease. Part A is a cross-sectional study design investigating the postulated bidirectional link between the gut and lung microbiomes in children suffering from respiratory or gastrointestinal conditions. Children with no GI or respiratory issues attending for orthopaedic care will be used as a benchmark for a healthy gut-lung axis. The main questions we aim to answer are: * What does a healthy gut-lung axis look like? * Do children with respiratory issues show an altered gut microbiome? * Do children with GI issues show an altered lung microbiome? Part B is a longitudinal study design, that aims to assess the effects of biologics on the gut-lung axis by comparing the gut and lung microbiomes in children with asthma at two time-points who are indicated to start biologics therapy (Asthma treatment) or will not receive biologics therapy (asthma control). Participants will provide: * airway samples (to investigate the lung microbiome) * blood samples (to assess inflammatory and metabolic factors which may mediate communication between the two sites) whilst under general anaesthetic for a treatment related to their standard of care * stool samples (to assess gut microbiome) * dietary information (food diary and/or food frequency questionnaire) to assess relationships between diet and the gut-lung axis.
