Filter by:The purpose of this study is to see if advanced endoscopic imaging may be helpful to accurately distinguish pathological tissue from normal tissue and guide therapy of endoscopically identified pathology.
The purpose of this study is to find out if transplant of fecal matter (stool), also known as fecal microbiota transplantation (FMT), from a healthy person into the intestines of children and young adults with Autism Spectrum Disorder (ASD). For this study children between the ages of 5-17years will be recruited over 2 years. Children will be recruited who receive an ASD diagnosis using the gold-standard Autism Diagnosis Observation Schedule -2 (ADOS-2) using module 1, 2 or 3 (none, limited or no moderate expressive language). Children diagnosed with these modules of the ADOS-2 may be at greater risk for GI disorders and rigid-compulsive behaviors. Additional assessment of rigid-compulsive behaviors and social communication will be done using the Repetitive Behavioral Scales-Revised (RBS-R) and Social Responsiveness Scale-2 (SRS-2), respectively. KBIT (the Kaufman Brief Intelligence Test) is used at baseline to obtain patient IQ. Total evaluation time is approximately 90 minutes. Following baseline symptom evaluation, a medical exam will be performed to determine whether each child is expressing specific GI symptoms. In addition, parents will fill out the Questionnaire for Pediatric Gastrointestinal Symptoms- Rome III (QPGS-III). Once an ASD diagnosis is confirmed, FMT treatment will be initiated, which typically occurs within 4-6 weeks of the initial diagnosis. Half 50% of the children (n=5) will receive the equivalent of 50 g of stools from a healthy donor into the jejunum through upper endoscopy and the other 50% off children (n=5) will receive Saline solution as Placebo control through upper endoscopy. Subjects will have a total of 5 visits within 24 weeks including phone call follow up on Day 7 after FMT.
This is a clinical trial of Microbiota Transplant Therapy (MTT) for adults with autism spectrum disorders (ASD) who have gastrointestinal problems. Previous research has shown that individuals with ASD have a low diversity of gut bacteria, and low diversity is generally associated with poor gastrointestinal (GI) health. We previously found that MTT therapy for children with ASD and GI symptoms was helpful in reducing their GI symptoms, reducing their ASD symptoms, and increasing their diversity of gut bacteria. This clinical trial will investigate the hypothesis that MTT therapy will be helpful for adults with ASD who have GI symptoms.
Evaluation of A Partially Hydrolyzed Whey Protein Infant Formula in Improving Functional Gastrointestinal Disorders (FGIDs) Symptoms
The purpose of this study is to learn more about the eating behaviors of children with chronic food refusal. Specifically, investigator's aim to see how the integrated Eating Aversion Treatment (iEAT) may affect a child's food consumption. The manual is a structured multidisciplinary treatment, including a psychologist and dietitian with consultation from a speech-language pathologist. The treatment is designed to increase the volume of foods a child eats and decrease their reliance on a feeding tube or formula. The manual includes informational handouts, data collection forms, and instructions to guide the increase in feeding demands while reducing reliance on formula to meet a child's nutritional needs. Children with chronic food refusal will participate in this study at the Marcus Autism Center. All children who enroll will receive the iEAT treatment. This involves 10 bi-weekly sessions that last approximately one hour, over the course of 5 months and a 1 month follow-up visit. Therefore, the study will last a total of 6 months.
The goal of the Precision Diagnosis in Inflammatory Bowel Disease, Cellular Therapies, and Transplantation (PREDICT) trial is to apply a systems-biology approach to enable precision diagnostics for the key immunologic outcomes for patients with Inflammatory Bowel Disease, Cellular Therapeutics and Transplantation. This approach will deepen the understanding of the molecular mechanisms driving auto- and allo-immune diseases and serve as a critical platform upon which to design evidence-based treatment paradigms for these patients. This research study will examine the immunology of auto- and allo-immune gastrointestinal disturbances such as Inflammatory Bowel Disease (IBD), Graft-versus-Host Disease (GVHD), and Functional Gastrointestinal Disorder (FGID), as well as the immune manifestations after CAR-T and other cellular therapeutics. The Investigators seek to use blood and tissue samples in order to better understand the mechanisms driving these diseases and their therapies. The Investigators further hypothesize that longitudinal systems-based immunologic analysis will enable the patient-specific determination of the molecular evolution of IBD, GVHD and the response to cellular therapeutics, as well post-transplant defects in protective immunity, and determine which pathways, when perturbed, can cause clinical disease. The discovery of these pathways will lead to improved diagnostic, prognostic and treatment approaches, and to personalized therapeutic decision-making for these patients.
This study is looking at the effect of semaglutide on subjects with nonalcoholic fatty liver disease.This study is comparing the change in early stages of scar tissue in the liver and fat deposition in the liver in people taking semaglutide and placebo (a dummy medicine). Participants will either get semaglutide or placebo; which treatment participants get is decided by chance. Semaglutide is a medicine under clinical investigation. That means that the medicine has not yet been approved by the authorities. Participants will need to self-inject medicine once daily for 72 weeks. The medicine should be injected under the skin in the stomach, thigh or upper arm. There are about 3 weeks before participants start the study medicine and 7 weeks after you stop it. The study will last for about 82 weeks in total. Participants will have 12 clinic visits, 6 phone calls and 4 visits to an MRI centre. The study includes MRI scans of the stomach. The MRI scans will take place at a different location. Participants will be excluded from the study if the study doctor thinks that there are risks for participants health. Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.
The Transition Navigator Trial (TNT) is a pragmatic randomized controlled trial evaluating the effectiveness of usual care plus a patient navigator service versus usual care plus newsletters and other educational materials, to improve transition outcomes among adolescents aged 16-21 who have chronic health conditions requiring transfer to adult specialty care. The study will provide urgently needed data to guide health care providers and policy makers regarding the provision of coordinated transition care. These results have the potential to: 1. Change care delivery 2. Improve health outcomes 3. Improve the experiences of young adult transition to adult care
This is a generic sample collection study for collecting blood, stool, rectal swabs, nasal washes, nasopharyngeal aspirates, nasopharyngeal swabs, throat swabs, nasal swabs, and urine from human sources. Subjects will be recruited from BioFire Diagnostics employees and from the general community. Subjects may be asked about recent or ongoing illness at the time of specimen collection and these symptoms will be recorded and attached to the sample. No other identifying information will be collected and the samples will be kept anonymous.The samples may be used internally or by external sites, such as the clinical study sites, for evaluating and determining performance characteristics of in vitro diagnostic devices.
The PHAGE study is designed to determine if a commercial prebiotic product can change the composition of bacteria in the gut for improved intestinal health. A prebiotic is defined as an indigestible dietary component that selectively enhances specific bacterial species in the intestines to confer a health benefit. In this study, the prebiotic a unique combination of bacteriophages, or viruses that infect bacteria. These phages are generally regarded as safe for human consumption and work by infecting bad bacteria in the gut, which allows beneficial bacteria populations to increase. The product, PreforPro, has shown to be effective in culture-based and animal studies, but its efficacy has not been demonstrated in humans. The goal of this study is to see if PreforPro consumption improves gut bacteria profiles in individuals relative to a placebo control and is associated with reduced incidence and severity of gastrointestinal distress.
