Active clinical trials for "Digestive System Diseases"

Researchers want to learn more about the day-to-day use of Iberogast in people who have functional and motility-related gastrointestinal (stomach and bowel) diseases. Functional and motility-related stomach and bowel diseases are conditions in which the functionality of the gut, mainly the gut muscles or the gut/brain axis is disturbed. Functional and motility related stomach and bowel diseases cause symptoms like heartburn, cramps and u pain of the upper and middle part of the belly, also known as functional dyspepsia (FD), and irritable bowel syndrome (IBS). IBS affects predominantly the lower digestive system and causes symptoms like pain of the belly, cramps, bloating, diarrhea, and constipation. In this study, the researchers want to learn more about Iberogast, a plant-based treatment. Iberogast is available to treat stomach and bowel diseases such as FD and IBS. Earlier studies with Iberogast have shown how well it works and how it affects the body. But, little is known about the day-to-day use of Iberogast and how satisfied patients are who take it. So in this study, the researchers want to learn more about Iberogast including: how well it works in day-to-day use how it affects the body, also referred to as tolerability how it is used day-to-day how safe it is how satisfied patients are who take it To answer these questions, the researchers will collect information from pharmacies in Germany. Patients who get Iberogast from these pharmacies to help treat their gastrointestinal disease will complete a questionnaire before, during and after taking Iberogast. The researchers will use the results from the questionnaires to learn more about: the disease details of the patients who are taking Iberogast the patients' symptoms while taking Iberogast if the patients' symptoms change after taking Iberogast how satisfied patients are with Iberogast if the patients had adverse events An adverse event is any medical problem that a participant has during a study. This study will include patients in Germany who: have functional stomach and bowel symptoms or disorders like FD or IBS take Iberogast to treat symptoms of their stomach and bowel disease are able to complete the questionnaire There will be no required tests or visits with a study doctor in this study. No treatments will be given as part of this study. The researchers will review information collected from patients who have decided for their own or by recommendation of their doctors or pharmacist to take Iberogast. The researchers will collect the results from the patient questionnaires from November 2017 to March 2018.

This study involves a comprehensive nutritional assessment of hEDS participants who have functional gastrointestinal disorders and dietary intervention to broaden their food choices and nutritional intake.

Non-randomized monocentric open cohort study vs historical comparative group testing the efficacy of a multimodal prehabilitation program (based on physical activity, nutritional support and mental preparation) for unfit patients based on nutrition, physical activity and mental preparation in reducing postoperative complications in elective major surgery

Our study aims to develop a screening test for biliary atresia (BA) using dry blood spot to improve patient survival by early diagnosis. Newborn screening dry blood spot will be examined for the direct bilirubin (DB), γ-GT or matrix metalloproteinase-7 (MMP-7) levels. These findings will promote early diagnosis for BA and hence improve the survival.

The Evolution® Biliary Stent System Clinical Study is a clinical trial on a commercially available device to gather physician experience with the Cook Evolution® Biliary Stent System for the palliation of cancer in the biliary tree. Patients will be treated as per usual medical practices.

This is a prospective study designed to assess safety and potential influence of the MiroCam on cardiac pacemaker and implantable cardiac defibrillator.

The purpose of this study is to collect epidemiological data in children and adolescents with chronic hepatitis B(CHB), in particular data on the prevalence of HBeAg positive disease with associated ALT levels , active HBeAg negative disease and decompensated CHB in the pediatric population. Family history and history of HBV transmission is essential to assess the course of the disease and can be used to determine the best mode of treatment This information will be used to assist with the feasibility and design of studies for the Novartis clinical pediatric development program, as the current epidemiology of ediatric CHB is not accurately known in Western countries or the rest of the world making pediatric studies difficult to plan and conduct. This study forms part of the Novartis Pediatric Investigational Plan, a post marketing approval commitment to the EMEA Pediatric Committee.

DESCRIPTION: Minimal data exists on the prevalence of gastroesophageal reflux disease in minority populations. Specific objectives of this K24 research project are to: (1) Provide an estimate of the prevalence of gastroesophageal reflux disease in an urban, African American population; (2) Determine whether specific risk factors including diet, tobacco use, physical activity, and psychosocial stress are important in the targeted population. We will also measure height, weight, and waist/hip circumference to determine the impact of central obesity on reflux. PUBLIC HEALTH RELEVANCE: This research will help doctors to understand the frequency and risks for esophageal reflux disease (heartburn) in African Americans.

The insufflation of air in the viscera is indispensable during endoscopy. However, the distension of the bowel that follows is often the cause of abdominal discomfort. Carbon dioxide (CO2) has been widely used for insufflation in endoscopy. CO2 insufflation is demonstrated in the literature to cause lower abdominal discomfort as it is quickly reabsorbed by the body. Endoscopic ultrasonography (EUS) is a method in which you associate the endoscopic view and the ultrasound vision obtained from the inside of the viscera. The diagnostic accuracy of EUS is undermined by the visual artifacts caused by the presence of air between the probe and the organ to be studied. Although the use of CO2 is already widely applied by many endoscopists, there are no studies to date concerning the use of CO2 during EUS from the point of view of the abdominal discomfort related to the procedure and/or the quality of the images obtained. The main purpose of the study is to assess whether the insufflation of CO2 results in a reduction of discomfort of the patients undergoing EUS. The study design is observational because no randomization or other interventions are planned; participants will be assigned to either air or CO2 insufflation according to the endoscopic room equipment (one room is equipped with CO2 insufflation while another endoscopic room is equipped just with air insufflation) and the results of the two groups will be compared. Among the secondary goals the investigators want to evaluate whether insufflation of CO2 is associated with a reduction in the dose required for patients sedation. Finally, the investigators want to clarify whether the use of CO2 is able to produce less visual artifacts than air and thus improve the quality of EUS images.

Brain imaging has shown abnormal brain activations in response to visceral stimulation in patients with the Irritable Bowel Syndrome (IBS) and Functional Dyspepsia (FD). To investigate the possible role of the Nucleus of the Solitary Tract (NTS), the primary relay station in the brainstem for vagal afferents, its activation in IBS and functional dyspepsia patients will be evaluated. Prior to this, an exploratory study in healthy volunteers will be conducted. This will be the first high magnetic field fMRI study (7T) evaluating the possible role of NTS activation in visceral abdominal pain. Moreover, this will be the first pharmacological fMRI study using duodenal capsaicin infusion as a chemical stimulus, which is more physiological than mechano-stimulation in the upper gastrointestinal tract.
