Probiotics Supplementation and Intestinal Microbiome in Neonates With Gastrointestinal Surgery

ProbioticsInfant4 more

Congenital defects of the gastrointestinal tract commonly require surgical intervention in the neonatal period. Intestinal surgery during this critical period of microbiome acquisition results in aberrant colonization of the gastrointestinal tract by several pathways. Surgical stress is known to cause disruption of the gut barrier and increase intestinal permeability and bacterial translocation. This process triggers exaggerated immune responses that lead to inflammation and sometimes infectious complications. Post-operative use of antibiotics has been shown to potentiate the growth of pathogenic bacterial species Adults with abdominal surgery who received post-op probiotics reported a significant reduction in surgical site infection, urinary tract infection, and combined infection. Currently, probiotics used only in the non-surgical population of infants. The main objective of this study is to determine the impact of probiotics administration on the intestinal microbiome in neonates undergoing intestinal surgery.

Pilot Study for Evaluation of Cryobiopsy and Correlation With Standard Forceps Biopsy

Gastrointestinal Disease

Environmental enteric dysfunction (EED) is a poorly understood condition characterized by intestinal inflammation and loss of barrier function that is prevalent in regions of the world with inadequate sanitation and hygiene. EED is a major driver of malnourishment, poor neurological development, stunting, oral vaccine failure, and infection, affecting 25% of all children globally and causing over a million deaths each year. Progress towards understanding EED and developing effective interventions has been hampered by an inability to evaluate the intestinal mucosa of populations in impoverished regions of the world where this condition is endemic. In order to prevent the deleterious and permanent sequelae of the disease, there is a need for effective diagnosis and intervention to be implemented in EED patients before the age of 2. Currently, the only means for directly evaluating the intestine is endoscopy with mucosal biopsy. Unfortunately, endoscopy is untenable for the study of EED because of limited resources and the high cost. As a result, there is a clear, unmet need for a less invasive tool that can be used in low-and-middle-income-countries (LMICs) to evaluate the intestine in population with EED. This work is supported by a grant from The Bill and Melinda Gates Foundation (BMGF). The overall goal is to provide a minimally invasive means of obtaining detailed infantile intestinal tissue information that is needed for the development of effective EED interventions. Obtaining biopsies will play a critical role in gathering the detailed intestinal tissue information. The purpose of this study is to explore the feasibility of utilizing a cryobiopsy probe to obtain biopsies in adults.

Nutraceuticals and Functional Foods

Systemic DiseaseSkin Diseases11 more

Supplements and functional foods are now readily available and usable by the general population. Many supplemnets are commonly used in poly-treated patients where interactions or adverse events may develop, therefore we evaluate in the rela life the use of nutraceuticals, their clinical effects and the development of adverse drug reactions

Sarcopenia and Physiology Assessments in Cancer Patients

Upper Gastrointestinal DisordersLower Gastrointestinal Disorders1 more

Primary Aim: To establish a reliable relationship between oxygen uptake (VO2) at estimated lactate threshold (AT) and CT-derived body composition measurments (e.g. muscle radiation attenuation), and to relate these to post-operative outcomes (i.e. post-operative complications or 1-year survival) in cohort of upper (UGI) and lower (LGI) gastrointestinal and hepatobiliary (HPB) cancer patients undergoing surgery +/- cancer therapies. Rationale:Objectively measured reduction of muscle radiation attenuation (i.e. Computed Tomography (CT) measured indices of muscle wasting) coupled with reduced physical fitness (measured objectively using Cardiopulmonary Exercise Testing (CPET)) will result in worse post-operative surgical outcome and reduced survival. Trial Design: Observational Sample size: See statistical analyses section for individual cohort power calculations Inclusion Criteria: Male or female patients, aged over 18 years old with UGI, LGI or HPB cancer undergoing surgery +/- cancer therapies; WHO performance status 0-2. Exclusion Criteria: Patients will be excluded if they have surgery for benign disease, a diagnosis of inflammatory bowel disease, patients physically unable to perform a CPET on a cycle ergometer, patients having no surgery performed or interim emergency surgery, patients lacking complete in-hospital morbidity and survival data. Primary Trial Endpoints: UGI patients - 2 year overall survival, LGI and HPB patients - post-operative complications (Calvien-Dindo and Composite Endpoint in pancreaticoduodenectomy)

Intestinal Inflammation in CF Patients

Cystic Fibrosis in ChildrenCystic Fibrosis Gastrointestinal Disease1 more

Cystic Fibrosis (CF) is a disease that affects salt and water transport in multiple organs. Many CF patients suffer from abdominal pain and this could be due to intestinal inflammation. However, so far we do not know how many of the CF patients actually do have intestinal inflammation when looking at intestinal specimens. There is a proven connection between chronic inflammation and developing colorectal cancer and over the years more CF patients are developing colorectal cancer. Thus, it becomes increasingly important to look for the presence of intestinal inflammation in CF patients since early treatment may improve their symptoms and reduce the risk for colorectal cancer.

Sucrase-isomaltase Deficiency as a Cause of Irritable Bowel Syndrome

Irritable Bowel SyndromeSucrose Intolerance Due to Sucrase-Isomaltase Deficiency3 more

Irritable bowel syndrome (IBS) is a functional disorder causing troublesome symptoms and reduced quality of life. It affects 10-20% of the population, hence creates large costs for society. About 30-40% of all IBS patients do not benefit from current treatment options. Sucrase-isomaltase (SI) deficiency is an unexplored condition, that may explain symptoms in IBS patients who experience no effect from today's treatments. Currently, a duodenal biopsy is the gold standard for the diagnosis of SI deficiency, however the condition is not well investigated. A 13C-labelled breath test holds promise as a non-invasive alternative, but it has not previously been validated. This project will address the knowledge gap related to a possible association between SI deficiency and IBS by addressing two research questions that have never been answered before. We aim to: Validate the 13C-labelled breath test as a diagnostic tool by assessing the strength of the association between the breath test and SI activity measured in duodenal biopsies Use the 13C-labelled breath test in a randomized dietary crossover trial comparing a starch and sucrose reduced diet (SSRD) with the standard low-FODMAP diet in IBS patients, to evaluate whether SI activity is associated with dietary changes according to symptom severity and gut microbiota composition
