Active clinical trials for "Digestive System Diseases"

Recurrent Abdominal Pain (RAP) in children is common and causes significant functional impairment and poor quality of life. Lifestyle factors such as diet, anxiety, and stress are important triggers of abdominal pains, but there is lack of high quality research evidence on optimal treatment modalities in children. This study aims to evaluate the effect of food elimination on abdominal pain frequency and severity in a cohort of children with abdominal pain associated Functional Gastrointestinal Diseases (FGID). The primary outcome will be a comparison of abdominal pain frequency and severity between standard therapy and targeted food elimination, based on IgG antibody results to a multiple food antigen panel. The investigators anticipate that 'targeted dietary elimination' as a treatment strategy will resolve abdominal pain and improve quality of life in children.

This study aims to test the effects of a Preoperative Relaxation intervention and an Intensified Surgery Patient Education on pre- and postoperative wellbeing and health in Patients Undergoing colorectal surgery.

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 purpose of this interventional study is to test and compare the effectiveness of two elimination diets-the 1-food elimination diet (1FED, milk only) and the 4-food elimination diet (4FED, milk, egg, wheat, and soy) for eosinophilic esophagitis (EoE). The study will also test the effectiveness of swallowed glucocorticoid therapy in some of the study participants for whom diet therapy was not effective.

The study was quasi-experimental including patients in two intervention and control groups. Three measurements were done: pretest, post-test, and a two-months follow-up. The study population included patients with irritable bowel syndrome(diagnosed by specialists and based on the criteria of Rome III), who referred to a general Hospital. Fifty two irritable bowel syndrome patients were selected and assigned to two experiment (26 cases) and control (26 cases) groups. The criteria below were considered in selection of patients. Inclusion criteria: 1) Patients should not have participated in other psychological interventions concurrently; 2) Participants had not reported diagnosis of non-functional gastrointestinal illnesses. 3) Women patients had not been in pregnancy; 4) Participants had not met diagnosis of schizophrenia and bipolar disorders. Exclusion criteria: Three or more absences in the group sessions Co-variate variables: 1) demo-graphical variables (age, birth order, and education); 2) clinical variables (global psychological status, mind-body attribution, and duration of disease).

The main objective is to assess the effect of an 8-week daily supplementation with IbSium® (probiotic yeast Saccharomyces cerevisiae CNCM I-3856) on the improvement gastro-intestinal disorders associated to the type C IBS (constipation predominant).

This trial aims to determine whether Hou Gu Mi Xi is an effective treatment for improving symptoms and indicators in patients with spleen qi deficiency and mild gastrointestinal disorder.

This randomized controlled trial aims to evaluate the treatment effects of an internet-delivered CBT-program for adolescents with irritable bowel syndrome.

The purpose of this study is to compare the effects of 5g of Daikenchuto (TU-100) three times per day (Daikenchuto [TU-100] is a botanical agent that modulates gastrointestinal nerves), and placebo on rectal sensation (sensation ratings of urgency to defecate and sensation threshold for pain) in response to rectal balloon distension by barostat in patients with IBS.

The Canadian College of Naturopathic Medicine is conducting a research study on Irritable Bowel Syndrome (IBS), a common condition in North America. It is a long term, recurring gastrointestinal disorder that is estimated to affect 30% of the general population. IBS is characterized by abdominal pain and cramps, and bowel dysfunction such as diarrhea and bloating. The medicines that are currently used to help people with IBS are not as effective as we would like them to be. These medicines are usually only prescribed to reduce the pain of IBS and not actually treat the disorder itself. Recently, scientists have found that probiotics (beneficial bacteria that live inside humans) may help reduce the painful symptoms and diarrhea that are part of IBS. This research is being conducted to determine whether this particular combination of three probiotic bacteria (named Lactobacillus gasseri, Bifidobacterium bifidum and Bifidobacterium longum) will reduce the symptoms of severe IBS.
