Filter by:The primary objective of this study is to obtain de-identified, clinically characterized, stool and plasma specimens for use in assessing new markers for the detection of neoplasms of the digestive tract.
It is recommended as the first line treatment regimen to eradicate Helicobacter pylori (HP), 7 or 14 days treatment of proton pump inhibitor (PPI) based triple therapy consisting of one PPI and two antibiotics, clarithromycin and amoxicillin. In the case of treatment failure, 7 or 14 days of quadruple therapy (PPI＋metronidazole＋tetracycline＋bismuth) is recommended. This study aims to investigate which duration would be better for eradication of HP. The study design is a randomized controlled trial. The patients were randomly assigned to 7 days or 14 days treatment groups. Primary endpoint was the eradication rate of PPI based triple therapy. Secondary endpoints were to compare the rate of drug compliance and side effects in both groups.
The purpose of this study is to establish the working protocols for a general biorepository with the specific aim of procuring tissues and bodily fluids from the human gastrointestinal tract from a diverse range of clinical patients at the UC Davis Medical Center. The establishment of a GI-specific biorepository will support future translational endeavors within the UC Davis campus by providing laboratories with readily available GI tissue and bodily fluid samples to test newly developed hypotheses with relative ease.
This pilot-study aims to evaluate the effect size and feasibility of internet-delivered cognitive behavior therapy (ICBT) for children (age 8-12 years) with pain-predominant functional gastrointestinal disorders (e.g. irritable bowel syndrome, functional abdominal pain and functional dyspepsia according to the Rome III criteria). The main component investigated in this study is exposure for gastrointestinal symptoms and for feared stimuli and situations. Children will participate along with one of their parents in the treatment. The parents will also receive specific modules with information on how to support their child in the treatment.
The investigators aimed to assess whether postoperative gum chewing improve intestinal functions.
This is an open-label, randomized, single dose, two-sequence, two-period crossover study, separated by 7 days washout interval from the first study drug administration. In this study, the bioavailability of Rabeprazole from Idiazole 20 milligram (mg) delayed release (DR) tablets and PARIET 20 mg DR tablets after a single oral dose administration of each to healthy adults under fasting conditions, will be investigated by determining the 90% confidence limits for the log-transformed ratio (Test product / Reference product) for the bioequivalence parameters. The influence of sequence, product and period effect will be tested by analysis of variance (ANOVA). In this study a total of 60 subjects plus 1-4 additional subjects will be enrolled and split into two groups (Group A and B) of 30 each. For each subject, a total of 33 blood draws will be done and the volume of blood will not exceed 300 milliliters (mL) for the study. PARIET is a registered trademark of EISAI Co. Limited.
Ulcerative colitis (UC) is a chronic relapsing inflammatory bowel disease (IBD). At the time of diagnosis it is not possible to predict the course of the disease, which can range from a few flares in a lifetime to uncontrollable disease leading to hospitalization, surgery and stoma. There is a continuous need to improve treatment as well as diagnostic and prognostic tools. This study evaluates the clinical efficacy, tolerability and feasibility of remote ischemic conditioning (RIC) in patients with moderate active ulcerative colitis (UC). The investigators hypothesize that RIC beyond the well known effect on reperfusion tissue damage has a clinically relevant anti-inflammatory effect in UC. RIC constitute a repeated brief and non-harmful suppression of blood circulation in a limb. The mechanism of action of RIC is likely to involve suppressed inflammation and cell death. Our study is a randomized clinical controlled study including 38 patients. Patients will receive RIC or sham for 10 consecutive days. The effect of RIC on active UC is evaluated by changes patient's symptoms, endoscopy findings, and various markers in the blood, faeces and the intestinal wall.
The clinical manifestation of autism spectrum disorder (ASD) is complex, with medical and mental health disruptions that occur with the three core behavioral criteria used for diagnosis (social behavior, communication, restricted interests/repetitive behavior). Co-occurring medical conditions, such as gastrointestinal dysfunction (GID), often are overlooked when designing research strategies to understand the mechanisms underlying the expression of ASD. This study was initially a collaboration between Children's Hospital Los Angeles (CHLA) and the Children's Hospital at Vanderbilt University. The current research project proposes to recruit subject at CHLA and the Center for Autism and Developmental Disorders (CAND), a Children's Hospital of Orange County and University of California Irvine (UCI) Health collaborative program. In Aim 1, the investigators will characterize GID in pediatric populations with ASD. Over a 12 month period, subjects will receive standard of care for their GID, typically functional constipation. The study population will be characterized with a standardized instrument for diagnosing functional GI disorders in children, the Questionnaire on Pediatric Gastrointestinal Symptoms, and with the clinical acumen of an experienced pediatric gastroenterologist. Nutritional information also will be collected to determine whether there are patterns of GIDs that correlate with dietary and nutritional status. The in-depth characterization and treatment of GIDs in children with ASD will provide a unique way of determining if ASD symptom and GID symptom improvement are related to each other. In Aim 2, the investigators will do in-depth assessment of each subjects functional status for social communication, emotional regulation, cognitive function, speech-language, sensory integration, and a biomarker of oxidative stress. The latter will be measured in urine samples over the course of one year. There are no direct interventions for autism symptoms in this study. Rather, subjects will receive standard of care for the GID diagnosis and secondary effects on ASD symptoms will be evaluated. Our power calculation shows that the investigators will be adequately powered with the proposed study design and recruitment targets. As part of the study, the investigators have developed a collaboration with investigators in the University of Southern California (USC) School of Engineering, in which the investigators will work with them to develop computational tools to assist in the characterization of videotaped Autism Diagnostic Observation Schedule (ADOS-2) assessments.
After institutional review approval, pregnant women that are scheduled for elective cesarean delivery will be approached for participation in the study. The study informed consent will be obtained. The study's time frame inclusive will be from 2013 till 2016. Patients will be randomized to regular diet within 6 hrs postoperative (Early group) versus remaining nothing per os (NPO, i.e nothing per mouth) for 12hrs, and the diet then advanced as tolerated after 12hrs (Routine Group) as standard postoperative protocol in the investigators' institution. Primary outcome will be time to pass flatus. Secondary outcomes will include hospital length of stay, postoperative nausea, vomiting and patient satisfaction. Randomization will be performed using a computer generated random list of numbers assigning patients to the 2 groups of the study. This list of random number assignments will be kept secure in an opaque envelope until the end of the study. Patients in the Early group will be started on regular diet within 6 hrs of surgery, whereas the routine group patients will be kept strict NPO 12hrs, and clear liquid diet will be started after 12hrs. Diet will be advanced as tolerated, i.e. if clears were tolerated or flatus or bowel movement occurred, patients will be started on solid foods. If diet not tolerated, a full liquid diet will be given instead. Consequently if patient tolerated full liquid diet, a regular diet will be then initiated. Patients will be discharged home only if they tolerate solid food with absence of emesis, have flatus or bowel movement. Time Zero is defined as time of skin incision.
This study is aimed at investigating the efficacy of placebo for symptom relief in children with abdominal pain related functional gastrointestinal disorders.
