Active clinical trials for "Digestive System Diseases"

This is a descriptive retrospective database analysis study in using database. All patients with a physician PPI prescription will be selected to estimate the PPI inappropriate use.

This cross-sectional survey study is to determine the prevalence of functional gastrointestinal (GI) disorders in the general population and to describe common triggers for food-related GI symptoms.

This is a single center, retrospective, propensity score-matched analyzed study. Patients who underwent gastroscopy and colonoscopy for physical examination in Qilu Hospital of Shandong University, China, from January 2017 to September 2018, were retrospectively reviewed to compare the incidence of gastrointestinal diseases diagnosed by endoscopy between physicians and general population.

Background: Persistent gastrointestinal symptoms have been described in patients who are considered in remission of their inflammatory bowel disease (IBD). These symptoms, attributed to Functional gastrointestinal disorders (FGID) in IBD, may have a significant impact of quality of life, and may be associated with fatigue, anxiety and depression. There is very little data regarding pediatric specificities of these FGID. Aims: The aim of the study is to evaluate the prevalence of FGID in pediatric patients with IBD in remission. Secondary aims are to investigate a possible association of FGID with fatigue, anxiety, depression and impacted quality of life in the patients, as well as anxiety and depression in the parents. Methods: This will be an observational, case-control study. All patients between 9 and 18 years old , with IBD in remission will be invited to participate. Questionnaires will be web-based and will evaluate: presence of FGID (Fr-qPGS), fatigue (FACIT-F), anxiety (SCARED-R), depression (CDI), quality of life (IMPACT-III). Parents will be invited to fill in web-based questionnaires on their symptoms of anxiety (STAI/Y-A and STAI/Y-B) and depression (BDI). Clinical parameters will be retrieved retrospectively from the chart. Level of remission will be confirmed by most recent blood tests and fecal calprotectin. Patients with FGID will be compared to patients without FGID in terms of clinical characteristics, disease phenotype and associated psychological comorbidities.

An International, multicenter, epidemiological observational study investigating the prevalence of Transthyretin-Related Familial Amyloidotic Polyneuropathy (TTR-FAP) in participants with small fiber polyneuropathy of no obvious etiology.

The primary objective is to determine the sensitivity and specificity of the Exact Colorectal Cancer (CRC) screening test for colorectal cancer, using colonoscopy as the reference method. Lesions will be confirmed as malignant by histopathologic examination. The secondary objective is to compare the performance of the Exact CRC screening test to a commercially available FIT assay, both with respect to cancer and advanced adenoma. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.

Under daily routine conditions and without any intervention by the sponsor regarding the selection of subjects, diagnostic procedures, therapeutic decisions (medicinal and non- medicinal therapy, dose, duration, etc.), routine assessments, the participating physicians (i.e. gastroenterologists) are asked to document relevant data in patients with gastrointestinal disorders.

Develop Registry tool

Incidence of cancer in 75+ years old is 16,500 new cases per year, more than fifty percent of people with cancerThey are very few therapeutic trials dedicated. Oncologists hesitate to treat them because they are either afraid of inducing toxicity or of breaking down quality of life. Consequently, we decided to launch a protocol with both oncologists and geriatricians which principal aim is to find out if geriatric assessment data can help to better predict for chemotherapy toxicity, loss of autonomy and survival. We plan to accrue 360 patients diagnosed for cancer, including digestive, pulmonary, prostate, lymphoma, bladder, ovary cancer for whom first-line chemotherapy is planned. Patients are initially classified according to usual methods of medical oncology practice into three groups: patients who can receive standard treatment, reduced standard treatment or treatment adapted to the frail condition. Around Aquitaine, , we organised seven teams composed of one geriatrician and one nurse. Two kind of teams were activated: one which cover ten treatment sites in Bordeaux area and six sedentary teams which worked half a day a week in designated hospitals . Geriatric evaluation included test of cognitive functions (MMS), nutritional status (MNA), co-morbidity (CIRS-G), mobility (Get up and Go), activities (ADL;IADL), quality of life (QLQ-C30), depression (GDS-15) and Lachs-Balducci screening. Patients have four geriatric evaluations : before treatment, day 1 cycle 2, day 1 cycle 4, day 1 cycle 7 and/or end of chemotherapy. Since September 2002, 177 patients have been included, 112 have finished: 47.3% have received four evaluations, 16.1% died before the end of protocol, 14.3% stopped because they were in progression and changed their treatment, 11.6% met administrative problem that didn't allow all evaluations, 7.1% declined after inclusion and 3.6% finished their treatment before. The following results have been obtained: before treatment, 73% of these patients were at risk of undernutrition (MNA< 23.5), about 1/3 had one or more inability or a risk of falls (38% IADL<6, 29% get up and go>20seconds, 27% ADL>1, 34% PS<1), 28% of them had altered cognitive functions (MMS<24), 29% were depressive (GDS-15>6), 25% thought they had poor quality of life (QLQ-C30<4). Protocol will be closed in September 2005.

The purpose of this study is to develop and validate a deep learning algorithm for the diagnosis of gastrointestinal diseases. Then, evaluate the accuracy this new artificial intelligence(AI) assisted recognition system in clinic practice.
