Active clinical trials for "Digestive System Diseases"

A feasibility study for monitoring and recording gastrointestinal (GI) myoelectric activity in subjects with suspected or diagnosed irritable bowel syndrome (IBS) and reports of GI pain and asymptomatic subjects without IBS and GI pain.

The purpose of this study is to determine the correlation between gastric residence time of the SmartPill Capsule and the time required for partial emptying of a standard radiolabeled meal as measured by gastric emptying scintigraphy for subjects 65 years of age and older.

This research is designed to study the reliability of the results of an AcuGraph in college students and faculty members with reported digestive symptoms

Systemic sclerosis (SSc) is characterized by autoimmunity and vasculopathy resulting in fibrosis of the skin and internal organs including the Gastrointestinal (GI) tract. Key unmet clinical needs are the availability of non-invasive biomarkers for early diagnosis of SSc-GI, further characterization of different stages of SSc-GI and SSc-GI treatment response. The investigators propose combining MRI FDG-PET with MRI T1-MOLLI mapping, which has been applied to cardiac imaging to quantify histologically correlated cardiac fibrosis. T1-MOLLI enables detection and quantification of diffuse fibrosis without the need for contrast. Aim 1: FDG-PET-MRI imaging (primary biomarker) and stool markers (secondary biomarker) will be compared between patients with VEDOSS/early SSc and those with late SSc not on immunosuppressive treatment. Aim 2: Evaluation of change in biomarker levels from pre-treatment baseline to 6 months (primary end-point) and 12-months (secondary end-point) following MMF treatment, in early SSc patients Using precision medicine approach in diagnosis and treatment evaluation, the investigators anticipate that this study will contribute significantly to advance management strategies for, and improve outcomes of SSc-GI disease.

The UK population is ageing. Whilst many people remain active and in good health as they get older, getting older is associated with the onset of many common medical conditions, as well as memory and mobility problems. There is a natural decline in heart and lung fitness with age, although this may be slowed by regular exercise and physical activity. The majority of digestive system problems that require operations (such as bowel cancer) are more common in older people. These operations can reduce an older person's ability to look after themselves and their quality of life. In some cases there is a trade-off between major surgery and a smaller operation or procedure with a lower chance of cure, but a faster rate of recovery and fewer problems immediately after the procedure. (Examples of smaller operations include bringing the bowel out onto the abdominal wall; creating a 'stoma'. Examples of procedures include inserting a tube inside the bowel or oesophagus to open up a blockage; insertion of a 'stent'). Some patients may be advised or may choose not to undergo any form of treatment. Deciding whether a person is fit enough to undergo a major operation is difficult and depends on patient factors (e.g. heart and lung fitness, other medical conditions, patient choice) and technical factors (location and spread of disease, availability of other options for treatment). In the outpatient setting there are a number of tests that can be used to try to work out what the risks of a major operation will be for a particular person. These can then guide different approaches to try to lessen these risks. Examples include exercise programmes, dietary supplements and anxiety management programmes in the period before the operation. In the emergency setting there is often not sufficient time before their operation but there are still a number of ways of improving the chances of a good recovery, such as meeting with a physiotherapist and early planning for discharge needs. This study aims to explore: Whether patients who have poor outcomes after surgery can be identified at the start of their surgical journey Whether there are specific patient characteristics that are associated with whether individual patients undergo major surgery or not. What patients feel about different support measures that may be put in place to try to improve outcomes

The purpose of this prospective registry is to assess long term data on efficacy, safety and clinical outcome of endoscopic placement of suture(s) and approximation of soft tissue within the Gastrointestinal tract for various GI tract disorders. The registry will evaluate technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this research study.

This is a retrospective and prospective multicenter registry to collect long-term data (1 year) on patients who have or will undergo Endoscopic resection such as EMR, ESD, EFTR, STER, etc. within the gastrointestinal tract for endoscopic treatment of early gastrointestinal neoplasms involving the resection of the superficial layers, mucosa and submucosa, of the tract wall. Subjects will be consented for medical chart review. The purpose of this retrospective and prospective registry is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Resection within the gastrointestinal tract (1 year). The registry will evaluate efficacy, technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this registry study.

The aim of the study is to elucidate the relationship between postnatal antibiotic administration on development of gut microbiota and possible protective influence of simultaneously administration of probiotic during antibiotic therapy on development of gut microbiota, functional gastrointestinal disorders of infancy, weight gain and body composition.

Observational study about the incidence of relative adrenal insufficiency in patients with cirrhosis and acute variceal bleeding; in patients with acute peptic gastrointestinal bleeding and without liver disease; and in patients with severe acute pancreatitis. This is a study using pharmaceutical specialties in the approved conditions of use.
