Active clinical trials for "Gastrointestinal Diseases"

Every year in France, 60,000 children are born prematurely (before 37 weeks of amenorrhea), and present an immaturity of their various systems, in particular the digestive system. This can result in feeding intolerance, which is expressed by abdominal distension, regurgitation or vomiting, irregular transit and abdominal discomfort. This feeding intolerance influences the length of hospitalization and can lead to necrotising enterocolitis, a major complication. In the Neonatal Intensive Care Units of Clermont-Ferrand hospital center, abdominal massages have been performed by physiotherapists for several years in order to improve the condition of the digestive system. However, the indication for abdominal massage is very dependent on the caregivers in charge of the newborn and the evaluation of the abdominal condition remains subjective with a great variability between examiners. Thus, some newborns will receive massage multiple times a day while others will not. Developmental care is essential for these premature infants, especially to avoid over-stimulation. It is important not to add care, such as massage, if it is not needed. It is therefore essential to properly assess the digestive status of premature babies in order to determine whether they have feeding intolerance and whether they require treatment with abdominal massage. To date, the investigators have not found measurable criteria or existing scales that can describe the digestive status of newborns. The main objective of the study is therefore to create and validate a clinical assessment scale for the abdominal status of preterm infants.

This study aims to investigate the knowledge, experience, and opinion on AI among gastroenterology (GI) patients, gastroenterologists, and GI-fellows, particularly concerning implementation and application of AI (in assisting clinicians) in healthcare. The secondary aims are to investigate (dis)advantages of AI use in healthcare and the availability of technical facilities and infrastructures within endoscopy to implement and apply AI in Dutch hospitals.

The aims of this research are to validate and develop of therapeutic strategies for patients with colorectal lesions in real time through pCLE(probe-based confocal laser endomicroscopy). Endomicroscopy is a technique for obtaining histology-like images from inside the human body in real-time. Total objections are 311 patients. Specific research topics are as below. Diagnosis and classification of colon polyps through pCLE Evaluation of the depth of invasion of colorectal cancer or lateral growth type tumor through the pCLE Differential diagnosis of colorectal submucosal tumor through the pCLE Differential diagnosis of ileocecal ulcers through the pCLE The study will be conducted to measure sensitivity, specificity, accuracy, amphoteric predict of pCLE diagnosis, and calculate the agreement of prediction compared to the pathological findings of lesions Check diagnostic agreement of technical phrases which are derived, the matching degree between observers, and will develope a new classification method based on this.

The purpose of this research study is to help us learn if children with Autism Spectrum Disorder (ASD) have gastrointestinal (stomach and intestine) problems more frequently than children without ASD do. The investigators hope to learn if children with ASD and gastrointestinal (GI) disorders have certain Problem Behaviors (PB), such as self-injury and aggression, more than children with ASD but no GI disorders do. The investigators want to learn if the Gastrointestinal Symptoms Questionnaire (GIQ) can help us tell which children with ASD also have gastrointestinal disorders. Hypothesis 1: Children with ASD exhibit high rates of symptomatic GI dysfunction that are not identified by current diagnostic evaluation. Hypothesis 2: Painful or discomfort-causing gastrointestinal dysfunctions contribute to an elevated incidence or severity of PB in an identifiable subpopulation of PB-expressing children. The investigators anticipate that the proposed study will raise the standard of medical care for children with ASD by improving current methods of identifying GI dysfunction and determining whether there is a significant relationship between GI dysfunction and PB in this population.

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 investigators' believe that it is important to medical practice to obtain information on how expandable metal stents work in a large group of patients who have metal stents placed in the gastrointestinal system. The purpose of this research study is to collect information on the stent placement in our facility and how the patients responded to the stent placement.

The current epidemiological study will be undertaken in GP's and specialized private doctors. In total, 85 general practitioners, orthopedics, rheumatologists and cardiologist will take part in the study. Data will be collected for 850 patients who visit their physician for medical conditions that require the use of acetylsalicylic acid and/or NSAIDS. The first 10 consecutive patients who visit their GP/orthopedic/rheumatologist/cardiologists and are currently receiving acetylsalicylic acid and/or NSAIDS will be included in the study.

The purpose of this study is to establish a reliable method for detection of rectal cancer patients with aggressive tumor at risk of metastatic disease and death by functional MRI.

The purpose of this study is to establish the working protocols for a general biorepository with the specific aim of procuring tissues and bodily fluids from the human gastrointestinal tract from a diverse range of clinical patients at the UC Davis Medical Center. The establishment of a GI-specific biorepository will support future translational endeavors within the UC Davis campus by providing laboratories with readily available GI tissue and bodily fluid samples to test newly developed hypotheses with relative ease.

Philips Healthcare has added a virtual path planner to the current commercially available XperGuide software platform and that has the potential to significantly reduce dose during image-guided needle interventions.
