Filter by:The objective of this study is to confirm the sensitivity of a stool DNA test for detection of colorectal cancer and pre-cancer. Another objective is to provide anonymous, clinically characterized specimens for a bio-repository for future colorectal cancer-related test development.
The objective of this study is to determine the safe use and tolerance of a peptide-based formula in children with gastrointestinal dysfunction and/or feeding intolerance.
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 IBS.
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.
The study aims to investigate how to give the diagnosis of Irritable Bowel Syndrome. The investigators compare two parallel groups of primary care patients, in the age of 18-50 years with gastrointestinal complaints where the GP suspects IBS. All included patients fulfil international diagnostic criteria (ROME III) and have no danger signals. Group 1: The diagnosis is based on the diagnostic criteria and few blod tests Group 2: The diagnosis is a diagnosis of exclusion after investigations with extended blod tests, examination for milk- and gluten intolerance, stoll for ova and parasites and scopy of the intestine. After receiving the diagnosis of Irritable bowel syndrome all patients are informed about the condition. The investigators follow the patients for 1 year. The investigators hypothesis is that the two investigation programmes (group 1 and 2)are equal with respect to the patients´ quality of life, symptoms and satisfaction and also with respect to finding of organic diseases.
The Cohort of Swedish Men began in 1997, when all men born between 1918 and 1952 and residing in two counties in central Sweden received a questionnaire including about 350 items concerning diet and other lifestyle factors. A second questionnaire was sent out in 2008-09.
The Swedish Mammography Cohort began in 1987-1990, when 66,651 women living in two counties in central Sweden completed a mailed questionnaire that included items about their diet, parity, age at first child's birth, history of breast cancer in family, weight, height, and education. Follow-up questionnaires have been sent out in 1997 and in 2008-09.
Study consists of 6 treatment cohorts of 12 subjects with chronic pain, opioid-induced bowel dysfunction, and opioid physical dependence. Total duration of treatment for each subject will be up to 28 days. Each subject will receive a single dose of study drug, administered orally in the morning of Day 15 under fasted conditions. Cohort 1: 0.1 mg of S-297995 or placebo. Cohort 2: 0.3 mg of S-297995 or placebo. Cohort 3: 1 mg of S-297995 or placebo. Cohort 4: 3 mg of S-297995 or placebo. Cohort 5: 0.03 mg of S-297995 or placebo. Cohort 6: 0.01 mg of S-297995 or placebo. The primary objective of the study is to evaluate the safety of single doses of oral S-297995 in subjects physically dependent on opioids
Doctors at MassGeneral Hospital for Children (MGHfC) are doing a research study to learn if a gluten free-dairy free (GFCF) diet is helpful in improving gastrointestinal symptoms associated with autism. Hypothesis: The gluten free/casein free diet (GFCF) will result in a higher proportion of subjects having reduction in gastrointestinal (GI) symptoms associated with autism spectrum disorders (ASD). Primary Study Objective: - To assess the effect of a GFCF diet on GI symptoms associated with ASD. Secondary Objectives: - To assess if improvements in GI symptoms result in improvements in autistic behavior when using a GFCF diet in the dietary management of GI symptoms associated with ASD - To determine the nutritional impact of a GFCF restrictive diet - To assess the role of food allergies in the manifestation of GI symptoms This is a 14-week study that requires between 5 & 9 office visits. All study related activities -including physical exams, blood samples and allergy testing - and an amino acid based supplement drink, are at no cost. Research study visits will take place at MGHfC in Boston, or at Newton Wellesley Hospital in Newton, or at Lurie Center/LADDERS in Lexington.
We are conducting a study to learn if probiotics, which are live bacteria found in food like yogurt and cheese, will improve symptoms of abdominal pain. Individuals participating in this study will take probiotic pills to see if this affects the expression of certain pain receptors in the intestines that relate to pain sensation. Biopsies will be taken from the colon before subjects take the probiotic pills. Subjects will then be given one of two different types of probiotic pills to take for 3-4 weeks. After taking the supplements, more biopsies will be collected to see if any changes have taken places. This study requires one screening visit and two clinic visits to UNC hospital. Subjects will also complete daily diary cards for 2 weeks during the study to record their symptoms and also collect 2 stool samples.
