Digestive peristalsis generates many artifacts that limit the abdominal and pelvic MRI interpretation. Apart from the hypoglycemia treatment in patients with diabetes, glucagon analog is also indicated for the digestive peristalsis reduction to reduce MRI artifacts. However, its use in PET/MRI is not described, given the risk of interaction with the metabolism of FDG. To assess the importance of this interaction on the FDG PET images, we report FDG PET/MRI images obtained with and without glucagon analog injection.

Background: Refluxate volume and pH drop following gastroesophageal reflux are mostly cleared by peristalsis. We evaluated the roles of primary volume clearing peristaltic wave (VCPW), secondary VCPW, post-reflux swallow-induced peristaltic wave (PSPW), and late primary peristaltic wave (LPPW) in refluxate clearance.
Methods: We retrospectively analyzed pH-impedance studies performed off therapy in 40 patients with typical esophageal symptoms.

Interstitial cells of Cajal in the plane of the myenteric plexus (ICC-MY) serve as electrical pacemakers in the stomach and small intestine. A similar population of cells is found in the colon, but these cells do not appear to generate regular slow wave potentials, as characteristic in more proximal gut regions. Ca handling mechanisms in ICC-MY of the mouse proximal colon were studied using confocal imaging of muscles from animals expressing GCaMP6f exclusively in ICC.

alpha toxin (CPA) is an important enterotoxemic pathogen linked to gastrointestinal disorders and previously associated with pulmonary disease in other mammals. A young female neotropical otter presented with lethargy, anorexia and steatorrhea, which developed within 24 hours. Veterinary care was provided under anesthesia, during which dehydration, intestinal hypermotility and pulmonary crackling sounds were identified.

Bowel sounds, a reflection of the gastrointestinal tract's peristalsis, are essential for diagnosing and monitoring gastrointestinal conditions. However, the absence of an effective, non-invasive method for assessing digestion through auscultation has resulted in a reliance on time-consuming and laborious manual analysis by clinicians. This study introduces an innovative deep learning-based method designed to automate and enhance the recognition of bowel sounds.

Background: Esophagogastric junction outflow obstruction (EGJOO) is a manometric diagnosis based on Chicago Classification version 4.0 (CC4.0) that requires confirmatory testing for clinical relevancy.
