Morbid obesity among Crohn's disease patients is on the rise and is associated with a higher rate of surgical complications after ileocolic resection.

Aim: Crohn's disease (CD) is regarded as a wasting disease, yet there is a growing population of CD patients with a body mass index (BMI) of 35 and above. The rate of postoperative complications is relatively high in CD patients but might be even higher in CD with morbid obesity (MO).

Methods: This was a retrospective study using a prospectively maintained database of all patients undergoing Ileocolic resection for CD between 2014 and 2021 in two referral centres, comparing postoperative complication rates according to BMI.

Utility of Abdominal Radiographs After Posterior Spinal Fusion for Neuromuscular Scoliosis.

Postoperative ileus, the temporary cessation of gastrointestinal motility leading to accumulation of fluid and gas in the bowel, is a common complication following posterior spine fusion (PSF) in patients with neuromuscular scoliosis (NMS). Abdominal radiographs (KUBs) are often ordered to differentiate between ileus and mechanical obstruction but expose patients to radiation, add cost, and may lead to unnecessary work up. The aim of this study was to determine how often KUBs led to a change in treatment after PSF in patients with NMS.

Thiamine Deficiency Is Common and Underrecognized in Emergency Department Oncology Patients.

Indoleamine 2, 3-dioxygenase 1 inhibition mediates the therapeutic effects in Parkinson's disease mice by modulating inflammation and neurogenesis in a gut microbiota dependent manner.

Abnormal tryptophan metabolism is closely linked with neurological disorders. Research has shown that indoleamine 2,3-dioxygenase 1 (IDO-1), the first rate-limiting enzyme in tryptophan degradation, is upregulated in Parkinson's disease (PD). However, the precise role of IDO-1 in PD pathogenesis remains elusive.

Development of novel GI-centric prostaglandin E receptor type 4 (EP4) agonist prodrugs as treatment for ulcerative colitis and other intestinal inflammatory diseases.

Prostaglandin E receptor type 4 (EP4) agonists have been shown to be effective in treating experimental ulcerative colitis (UC) in animals and in human clinical trials, but their development has been impeded by unacceptable systemic side effects. In this study, a series of methylene phosphate prodrugs of a highly potent and selective prostaglandin EP4 receptor agonist were designed to target and remain localized in the gastrointestinal (GI) tract after either oral or rectal instillation. The prodrugs were designed to be converted to liberate active EP4 agonist by intestinal alkaline phosphate (IAP), a ubiquitous enzyme found at the luminal of the intestinal wall thus exposing the colon epithelial barrier while reducing systemic exposure to the active agonist.
