Tools to detect human norovirus infectivity have been lacking. Using human intestinal enteroid cultures inoculated with GII.Pe-GII.4 Sydney-infected fecal samples, we determined that a real-time reverse transcription PCR cycle threshold cutoff of 30 may indicate infectious norovirus. This finding could be used to help guide infection control.

Mitrofanoff complications: time-to-event analysis of split versus intact appendix and meta-analysis.
World J Urol
January 2025
Division of Urology, Department of Surgery, The Hospital for Sick Children, Toronto, ON, Canada.
Objectives: To assess the complication rates associated with split versus intact appendix Mitrofanoff procedures using a single-center retrospective analysis and a systematic review with meta-analysis.
Subjects And Methods: The study comprised a retrospective cohort analysis at a single institution, analyzing patients who underwent a laparoscopic-assisted Mitrofanoff with or without splitting the appendix from 2005 to 2016. The focus was on complications related to both Mitrofanoff and ACE channels.
Unexpected finding of encapsulating peritoneal sclerosis: mind the cocoon.
BMJ Case Rep

Nephrology and Transplantation, Erasmus MC, Rotterdam, The Netherlands
Here, we present a fatal case of a man in his 40s with encapsulating peritoneal sclerosis (EPS). In retrospect, a spot diagnosis on the abdominal CT scan. The patient presented with progressive abdominal complaints of pain and vomiting over the last 2 months.

Alterations in tissue expression levels of both retinol-binding protein 2 (RBP2) and retinol-binding protein 4 (RBP4) have been associated with metabolic disease, specifically with obesity, glucose intolerance and hepatic steatosis. Our laboratories have shown that this involves novel pathways not previously considered as possible linkages between impaired retinoid metabolism and metabolic disease development. We have established both biochemically and structurally that RBP2 binds with very high affinity to very long-chain unsaturated 2-monoacylglycerols like the canonical endocannabinoid 2-arachidonoyl glycerol (2-AG) and other endocannabinoid-like substances.

Background: Non-absorbed dietary emulsifiers, including carboxymethylcellulose (CMC), directly disturb intestinal microbiota, thereby promoting chronic intestinal inflammation in mice. A randomised controlled-feeding study (Functional Research on Emulsifiers in Humans, FRESH) found that CMC also detrimentally impacts intestinal microbiota in some, but not all, healthy individuals.
Objectives: This study aimed to establish an approach for predicting an individual's sensitivity to dietary emulsifiers via their baseline microbiota.
Assessing the impact of TiO nanomaterials on intestinal cells: new evidence for epithelial translocation and potential pro-inflammatory effects.

Understanding the potential impact of nanomaterials (NMs) on human health requires further investigation into the organ-specific nano-bio interplay at the cellular and molecular levels. We showed increased chromosomal damage in intestinal cells exposed to some of in vitro digested Titanium dioxide (TiO) NMs. The present study aimed to explore possible mechanisms linked to the uptake, epithelial barrier integrity, cellular trafficking, as well as activation of pro-inflammatory pathways, after exposure to three TiO-NMs (NM-102, NM-103, and NM-105).
