Filter by:Researchers are looking at the effects of a cannabidiol medication on stomach function in people with gastroparesis (a paralyzed stomach) and people with dyspepsia (an upset stomach caused by improper functioning of the stomach's muscles or nerves).
This study evaluates the effect of auricular neurostimulation on mitochondrial bioenergetics and inflammation through vagal nerve modulation via non-invasive percutaneous electrical nerve field stimulator in children with functional gastrointestinal disorders.
The purpose of this study is to evaluate the efficacy of a hypnotherapy treatment program for functional dyspepsia that can be self-administered using on-line audio recordings. This is a non-randomized study. All patients will receive 7 sessions of hypnotherapy treatment administered over a 12-week period. The primary objective of the study is to determine the feasibility and acceptability of the self-administered hypnotherapy program. The secondary objective is to evaluate the effect of the treatment on participant reported symptom severity, quality of life, anxiety and depression.
Background and aims: A low-fat diet has been traditionally recommended after cholecystectomy although evidence is lacking. The main aim of the study is to assess either if digestive symptoms improve following the operation and if the restriction of fat in diet does influence these symptoms. Methods: Symptoms have to be prospectively assessed by the GIQLI score (Gastrointestinal Quality of Life Index) at baseline, and one month after cholecystectomy. A low fat diet or equilibrated diet is randomly assigned to patientes distributed in two groups (N=80) candidates to gallbladder removal. Patients have to follow the prescribed diet and complet a questionnaire of symptoms (GIQLI Symptomantic score).
This is an exploratory neurophysiological study that will determine the impact of non-invasive brain stimulation on autonomic regulation, with a focus on gastrointestinal function. These studies should provide a basis for future brain-based neurotherapeutic strategies in patients with functional GI disorders.
The purpose of this prospective cohort study is to compare upper GI symptoms and endoscopy findings in Canada with Japan and Iran, and correlate this with the upper GI microbiome. The investigators plan to recruit 500 new patients referred for upper GI endoscopy in Canada (McMaster University) and 500 in Japan (Tohoku University Hospital) and 500 from Iran (Tehran University of Medical Sciences). Written consent will be obtained from all participants. Patients will complete three symptom questionnaires and a demographic one before endoscopy. Then saliva collection device will be applied for collecting saliva and microbiota from the oral cavity. Esophagogastroduodenoscopy (EGD) will be performed thereafter and brushing of the esophagus, stomach, and the duodenum will be done using a sterile sheathed brush (one for each site) to sample collect gut microbiota and gastric biopsies will be done for assessing H.pylori status. In addition, a group of these patients will undergo measurement of nitrate reductase activity (NRA) in their oral cavity. This will be done on twenty erosive gastro-esophageal reflux disease (GERD) patients, twenty non-erosive GERD patients, and twenty patients without any endoscopic or clinical GERD. This latter part of the study will be done at the Canadian and Iranian sites only. Bacterial community profiling of the 16S rRNA gene will be carried out using paired end reads of the V3 region. Triplicate amplifications will be pooled for 150 or 250 nt paired-end Illumina sequencing in the McMaster Genome Center. For specific substudies analysis of the mycome will also be carried out.
Researchers are trying to understand why people with indigestion and diabetes mellitus have gastrointestinal symptoms and in particular to understand whether symptoms are related to increased sensitivity to nutrients in the small intestine. As part of this investigation, a medication called ondansetron will also be studied to determine its effects on gastrointestinal function and associated symptoms.
This study aims at evaluating efficacy Clostridum Butyricum Capsule and Bacillus Coagulans Tablets in H. pylori eradication. It is hypothesized that Clostridum Butyricum Capsule , Bacillus Coagulans Tablets monotherapy or Clostridum Butyricum Capsule plus Bacillus Coagulans may have some positive effect on H. pylori eradication.
Functional dyspepsia (FD) is a common chronic gastrointestinal (GI) disorder. Rikkunshito, a traditional Japanese Kampo medicine, has shown efficacy in improving FD symptoms in controlled trials in Japan. Its putative benefit for European patients has never been investigated. Further, its exact mechanism of action is incompletely elucidated. This study aimed to examine the effect of rikkunshito on gastric motility and GI symptom perception in FD in a randomized, placebo-controlled, cross-over study. Intragastric pressure (IGP) was assessed using high-resolution manometry as an indirect measurement of gastric accommodation and gastric motility.
Refractory Functional Dyspepsia (FD) means a state that no symptom was improved in spite of appropriate treatment for the FD. It may be challenging to discriminate the symptoms of FD from the symptoms of bile dyspepsia resulting from the biliary system. As the bile dyspepsia may induce epigastralgia as with functional dyspepsia and both imaging medical tests and blood tests show normal findings, it is difficult to discriminate it from the FD with only these tests. Thus this study intends to perform a therapeutic use clinical study for efficacy and safety on symptom improvement by administrating CNU capsule to the patients with RFD.
