Active clinical trials for "Gastrointestinal Diseases"

The primary objective of this clinical trial is to test the tolerance and practicality of the new device Module AOX. The secondary objective is to determine the changes in oxidative, antioxidative status, plasma free amino acids, and various immune parameters in critically ill patients receiving the enteral nutrition with and without using Module AOX.

There is evidence for the use of a diet low in short chain fermentable carbohydrates (low FODMAP diet) in the management of functional gut symptoms, such as abdominal pain and bloating. However, the provision of advice on the low FODMAP diet can be challenging due to limited resources and the need for a dietitian with expertise in the low FODMAP diet. The aim of this study is to assess the feasibility in terms of recruitment and retention in planning a future trial. The purpose of the future trial will be to investigate the clinical and cost effectiveness, as well as the acceptability of different education methods of the low FODMAP diet for the treatment of IBS. To date, there are no studies on the implementation of the low FOMDAP diet using a mobile app or leaflets in the education of the low FODMAP diet. Therefore, a feasibility study design was chosen in order to obtain key data on recruitment and retention rates at each study group.

This is a quality improvement health services study in the Division of Gastroenterology at Beth Israel Deaconess Medical Center (BIDMC).

Patients with fat malabsorption due to Crohn's disease, ulcerative colitis, or other causes including cystic fibrosis, among others, or who have undergone gastric bypass have increased incidence of vitamin D deficiency relative to the general population. Given that vitamin D is fat soluble and absorbed in the proximal small intestine, it has been documented that vitamin D deficiency in people with a fat malabsorption syndrome is due to decreased absorption of vitamin D. The amount of vitamin D produced from winter sunlight (in Boston, MA) and dietary sources will negligibly raise blood vitamin D levels in these patients, and oral vitamin D supplementation may have limited efficacy due to malabsorption. A variety of UV light sources have been developed and sold as in-home tanning devices and to produce vitamin D in reptiles. The efficacy of correcting vitamin D deficiency by the skin exposure to an artificial source of UVB radiation in patients with fat malabsorption syndromes (Crohn's disease, ulcerative colitis, or cystic fibrosis) or after gastric bypass surgery has not been studied. The investigators have conducted a pilot study in healthy adults that demonstrated that exposure to the lamp raised the blood level of 25-hydroxyvitamin D with no side effects. The main purpose of this study is to evaluate the effect of the FDA approved artificial source of ultraviolet (UVB) radiation (Sperti® lamp) in improving vitamin D status in patients with fat malabsorption syndromes and patients who have undergone roux-en-Y gastric bypass surgery.

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: Change care delivery Improve health outcomes Improve the experiences of young adult transition to adult care

This is a Phase 1, multicenter, nonrandomized, open-label, parallel-group study in participants with mild or moderate hepatic impairment, and in participants with normal hepatic function. Degrees of hepatic impairment will be determined during screening by the participant's score according to Pugh's Modification of Child's Classification of Severity of Liver Disease. Participants will be enrolled in Groups 1 through 3 as follows: Group 1 (mild hepatic impairment): A total of approximately 8 participants with a Child-Pugh score of 5 to 6. Group 2 (moderate hepatic impairment): A total of approximately 8 participants with a Child-Pugh score of 7 to 9. Group 3 (normal hepatic function): Approximately 8 to 16 participants will be matched to Participants in Groups 1 and 2. Normal hepatic function participants are allowed to match multiple hepatic impairment participants. Participants will be matched by sex, age (± 10 years), weight (± 20%), and smoking status.

Unsedated or slightly sedated colonoscopy has fast recovery time, less cost and lower or no incidence of drug-related side effects. May be slightly painful or discomforting for the patient. Based on numerous recent reports, the investigators designed this randomized controlled trial hypothesizing that the use of warm water irrigation versus air insufflation during the insertion phase of colonoscopy might increase the global tolerability of the examination and the proportion of patients undergoing complete colonoscopy without sedation or with a low dose of sedatives.

It is hoped that different forms of the same medicine, called PVP001, PVP002, and PVP003, will help people with celiac disease. Both healthy adults and adults with celiac disease will take part in this study. There are many main aims of the study. To check if participants have side effects from different forms of the study medicine. These forms are called PVP001 (liquid in a cup), PVP002 capsule, and PVP003 tablet. To check how well PVP003 breaks down gluten. To check how much PVP003 participants can take without getting side effects from it. The study is in 4 parts. At the start of each part of the study, the study doctor will check to determine who can take part at the first study visit. Different groups of participants will be in different parts of the study. In all parts of the study, some participants will take 1 of the 3 forms of study medicine. Others will take a placebo. In this study, a placebo will look like the form of study medicine but will not have any medicine in it. This means that a placebo can either look like PVP001 liquid in a cup, the PVP002 tablet, or the PVP003 tablet. In Part 1, different small groups of participants will take lower to higher doses of PVP001 or PVP002 or a placebo. This is to work out the best dose of study medicine to take in other parts of the study. After treatment, participants will regularly visit the clinic to check that they have no problems with their treatment, including any side effects from their treatment. In Part 2, different small groups will take different doses of PVP001 or PVP002 or a placebo, either with or without a meal that has different amounts of gluten in it. This is to check if PVP001 or PVP002 has broken down gluten in the body. Participants will visit the clinic after treatment to check how much gluten has been broken down in the body. In Part 3, different small groups will take different doses of PVP003 or a placebo, either with or without a meal that has gluten in it. This is to check if PVP003 has broken down gluten in the body. Participants will visit the clinic after treatment to check if more gluten has broken down in the body. In Part 4, different small groups will take PVP003 or placebo 3 times a day for 5 days. After treatment, participants will visit the clinic to check that they have no problems with their treatment, including any side effects from their treatment.

The investigators hypothesized that with the administration of the nutritional supplement Ocoxin-Viusid® is expected to improve the quality of life and enhance tolerance to chemotherapy in at least 70% of patients diagnosed with advanced pancreatic adenocarcinoma, treated at the "Hermanos Ameijeiras" Surgical Clinical Hospital. Phase II clinical trial, open, multicenter, nonrandomized.

Researchers are trying to learn more about how individuals break down and process specific medications based on their genes. Pharmacogenomics (PGx) is a new, specialized field within individualized medicine. PGx is the study of how genes may affect the body's response to, and interaction with, some prescription medications. Genes carry information that determines things such as eye color and blood type. Genes can also influence how individuals process and respond to medications. Depending on genetic make-up, some medications may work faster or slower or produce fewer side effects.
