A new intestinal model for analysis of drug absorption and interactions considering physiological translocation of contents.

Drug Metab Dispos 2021 May 7. Epub 2021 May 7.

Graduate School of Pharmaceutical Sciences, Chiba University, Japan

Precise prediction of drug absorption is key to the success of new drug development and efficacious pharmacotherapy. In this study, we developed a new absorption model, the advanced translocation model (ATOM), by extending our previous model, the translocation model. ATOM reproduces the translocation of a substance in the intestinal lumen using a partial differential equation with variable dispersion and convection terms to describe natural flow and micro-mixing within the intestine, under not only fasted but also fed conditions.

Pembrolizumab-caused polyradiculoneuropathy as an immune-related adverse event.

Neuropathology 2021 May 3. Epub 2021 May 3.

Department of Neurology, National Hospital Organization Kure Medical Center and Chugoku Cancer Center, Kure, Hiroshima, Japan.

Immune-related adverse events (irAEs) commonly involve the gastrointestinal tract, endocrine glands, skin, and liver, and rarely the nervous system. The pathomechanism of irAEs in the nervous system is unclear, and so characterizing these severe toxic effects is a priority, even if irAEs are uncommon in the nervous system. Our patient presented subacute muscle weakness and dysesthesia with colitis as irAEs caused by pembrolizumab, one of the anti-programmed death-1 (PD-1) antibodies. Read More

Onset of Skin, Gut, and Genitourinary Prodromal Parkinson's Disease: A Study of 1.5 Million Veterans.

Mov Disord 2021 May 3. Epub 2021 May 3.

Department of Neurology, Oregon Health and Science University, Portland, Oregon, USA.

Background: Prodromal Parkinson's disease of skin, genitourinary, and gastrointestinal systems offers a unique window for understanding early disease pathogenesis and developing disease modifying treatments. However, prior studies are limited by incomplete timing information, small sample size, and lack of adjustment for known confounders. Verifying prodromal timing and identifying new disorders in these accessible organs is critically important given their broad use. Read More

J Surg Case Rep 2021 Apr 22;2021(4):rjab093. Epub 2021 Apr 22.

College of Medicine, Alfaisal University, Riyadh, Saudi Arabia.

Amyloidosis is a disorder characterized by deposition of abnormally folded proteins in the extracellular space of various tissues and organs, possibly leading to their dysfunction. In the majority of cases, amyloidosis presents with systemic involvement including the gastrointestinal tract; however, localized gastroduodenal amyloidosis is rare. We report a case of gastroduodenal amyloidosis in a 36-year-old male with multiple comorbidities who presented with right upper quadrant abdominal pain. Read More

Gastroprotective Effects of Polyphenols against Various Gastro-Intestinal Disorders: A Mini-Review with Special Focus on Clinical Evidence.

Molecules 2021 Apr 6;26(7). Epub 2021 Apr 6.

School of Nutrition, Chung Shan Medical University, 110, Section. 1, Jianguo North Road, Taichung 40201, Taiwan.

Polyphenols are classified as an organic chemical with phenolic units that display an array of biological functions. However, polyphenols have very low bioavailability and stability, which make polyphenols a less bioactive compound. Many researchers have indicated that several factors might affect the efficiency and the metabolism (biotransformation) of various polyphenols, which include the gut microbiota, structure, and physical properties as well as its interactions with other dietary nutrients (macromolecules).

Endocannabinoids and the Gut-Brain Control of Food Intake and Obesity.

Nutrients 2021 Apr 7;13(4). Epub 2021 Apr 7.

Division of Biomedical Sciences, School of Medicine, University of California Riverside, Riverside, CA 92521, USA.

Gut-brain signaling controls food intake and energy homeostasis, and its activity is thought to be dysregulated in obesity. We will explore new studies that suggest the endocannabinoid (eCB) system in the upper gastrointestinal tract plays an important role in controlling gut-brain neurotransmission carried by the vagus nerve and the intake of palatable food and other reinforcers. A focus will be on studies that reveal both indirect and direct interactions between eCB signaling and vagal afferent neurons. Read More

Gastrointestinal stromal tumors (GISTs) are common mesenchymal tumors of the gastrointestinal tract (GIT), usually occur as a solitary neoplasm. Inflammatory florid polyp (IFP) is a solitary rare benign lesion of the gastrointestinal tract, mainly occur in the gastric antrum, whose atypical presentation can mimic GISTs or other malignant tumors, therefore the synchronous occurrence of GISTs and IFP is extremely rare. We had a case of a 58-year-old man that was presented with recurrent epigastric pain and recurrent melena. Read More
