Filter by:The objectives of this study are to examine the effects of ethnicity, gender, and proton pump inhibitor (PPI, omeprazole), on the human gut microbiome. The investigators hypothesize that PPI therapy might perturb microbial communities and alter the gut microbiome. Young, healthy subjects of Chinese, Malay and Indian ancestry, were enrolled. They were required to provide a baseline stool sample (Day 1) and were then given a course of omeprazole at therapeutic dose (20 mg daily) for a duration of 7 days. Stool samples were collected again on Day 7 and Day 14 (one week after stopping omeprazole). The DNA samples were subjected to 16S ribosomal ribonucleic acid (rRNA) sequencing.
This pilot clinical trial studies how well a swallowable sponge cell sampling device and next generation sequencing work in detecting esophageal cancer in patients with low or high grade dysplasia, Barrett esophagus, or gastroesophageal reflux disease. Checking biomarkers in abnormal esophageal cells using a swallowable sponge cell sampling device and next generation sequencing may improve diagnosis and treatment of esophageal cancer.
Obesity is a strong risk factor for GERD. This study assessed the role of obesity among patients having erosive GERD and controls.
The purpose of this study is to determine the efficacy and safety of dexlansoprazole compared to placebo in relief of daytime and nighttime heartburn over 4 weeks in Chinese participants with symptomatic non-erosive Gastroesophageal Reflux Disease (GERD).
This study is designed to evaluate the efficacy and tolerability of ilaprazole relative to that of esomeprazole in healing erosive esophagitis and resolving accompanying symptoms of GERD.
Due to several promoting factors, gastro-esophageal reflux (GER) is very frequent in preterm infants. To limit the potentially harmful widespread of pharmacological treatment, a step-wise approach, which firstly undertakes conservative strategies, is currently considered the best choice to manage GER in the preterm population. Among the most common conservative strategies, postural measures seem to effectively reduce GER features in symptomatic preterm babies, whereas feed thickening is almost ineffective. Due to their prematurity, preterm infants <34 weeks gestation are often unable to coordinate sucking, swallowing and breathing, thus requiring a feeding tube to ensure adequate enteral intakes. Continuous feeding and boluses are the most common techniques of enteral tube feeding in Neonatal Intensive Care Units; at present, however, the effects of these techniques on GER features have not been clearly established. This observational, prospective and explorative study primarily aims to evaluate the effect of different techniques of enteral tube feeding on GER frequency and features in symptomatic preterm infants (gestational age ≤33 weeks) undergoing a diagnostic combined pH and multiple intraluminal impedance (pH-MII) for GER evaluation.
Using an active cohort of children in whom Airway and gastrointestinal endoscopy will be performed, investigators will conduct a chart review to obtain relevant clinical data and the investigators will use an aliquot of airway sample obtained during the clinically indicated bronchoscopy for microbiome analysis. A case-control study design will be used to study whether subjects with CC with GER have a distinct lung microbiome and increased inflammation as compared with subjects with CC without GER and to determine whether the microbiome and degree of inflammation is related to the type of GER (acidic versus nonacidic).
Using genetic information about the individual to pick the right drug for the right disease at the right dose defines personalized medicine. This pilot study seeks to institute pharmacogenomic testing, that is identifying genetic variation that influences patient response to drugs, into the Nemours Children's Health system. We propose to initiate the study by identifying genetic differences in cyp2c19, a gene that is responsible for a certain enzyme in the liver that metabolizes many drugs including a class of drugs called proton pump inhibitors (ppi; Prevacid, Nexium). PPIs are used to treat heartburn and other symptoms of gastroesophageal reflux disease (gerd) and are extensively used in pediatrics. Chronic use of PPIs can cause serious side effects including cold, pneumonia and stomach infections, which gets worse at higher doses. Children who poorly metabolize drugs because of genetic variation in cyp2c19 should get lower doses of PPIs than children who metabolize PPIs normally. Our pilot study will genotype children with gerd or other stomach acid mediated conditions for which a PPI is prescribed using a sample of spit to determine which dose of PPI they get based on the form of the cyp2c19 gene they have. We will study 120 children 2-17 yo diagnosed with gastroesophageal reflux disease (gerd) or other stomach acid mediated conditions for which a ppi is prescribed . Genetic results are available in < 60 minutes, and their doses are determined by their doctor based on genetic results. This study will allow us to gain valuable experience that will be used to expand our genetic program to other genes and drugs.
The aim of Patient-Centred Innovations for Persons With Multimorbidity (PACE in MM) study is to reorient the health care system from a single disease focus to a multimorbidity focus; centre on not only disease but also the patient in context; and realign the health care system from separate silos to coordinated collaborations in care. PACE in MM will propose multifaceted innovations in Chronic Disease Prevention and Management (CDPM) that will be grounded in current realities (i.e. Chronic Care Models including Self-Management Programs), that are linked to Primary Care (PC) reform efforts. The study will build on this firm foundation, will design and test promising innovations and will achieve transformation by creating structures to sustain relationships among researchers, decision-makers, practitioners, and patients. The Team will conduct inter-jurisdictional comparisons and is mainly a Quebec (QC) - Ontario (ON) collaboration with participation from 3 other provinces: British Columbia (BC); Manitoba (MB); and Nova Scotia (NS). The Team's objectives are: 1) to identify factors responsible for success or failure of current CDPM programs linked to the PC reform, by conducting a realist synthesis of their quantitative and qualitative evaluations; 2) to transform consenting CDPM programs identified in Objective 1, by aligning them to promising interventions on patient-centred care for multimorbidity patients, and to test these new innovations' in at least two jurisdictions and compare among jurisdictions; and 3) to foster the scaling-up of innovations informed by Objective 1 and tested/proven in Objective 2, and to conduct research on different approaches to scaling-up. This registration for Clinical Trials only pertains to Objective 2 of the study.
The study will be evaluating the efficacy and safety of a contrast drug in pediatric renal ultrasound.
