January 2025

Juliet Keidan Institute of Pediatric Gastroenterology Hepatology and Nutrition, Shaare Zedek Medical Center, The Hebrew University of Jerusalem, Eisenberg R&D Authority, P.O. Box 3235, 9103102, Jerusalem, Israel.

Background: To advance personalized medicine in pediatric Crohn's disease (CD), we aimed to explore the utility of serological biomarkers in predicting response to anti-tumor necrosis factor (TNF).

Methods: Children with CD were enrolled at initiation of anti-TNF and followed prospectively at 4 and 12 months thereafter, as well as at last follow-up. At baseline, 10 serological markers of the "PROMETHEUS® IBD sgi Diagnostic test" were measured, including pANCA, ASCA IgG and IgA, anti-CBir1, anti-OmpC, anti-A4-Fla2, anti-Fla-X, SAA, ICAM-1 and VCAM-1.

Zebrafish () are a good model for cancer research including studies on chemotherapy treatments. We treated wild-type and deletion mutant zebrafish embryos at 24 h post-fertilization with 1 µM of the topoisomerase I inhibitor, camptothecin (CPT), for 4 h to catalogue gene expression changes induced by this DNA damage treatment and to understand if these changes are influenced by loss of miR-34a. The 4 sample groups of 3 independent biological samples consisting of 30 embryos each were analyzed by RNA-sequencing using the recently updated zebrafish transcriptome annotation based on GRCz11, which enabled a more complete and sensitive read mapping and gene assignment than standard annotations.

AI-PEDURO - Artificial intelligence in pediatric urology: Protocol for a living scoping review and online repository.

J Pediatr Urol

October 2024

Division of Urology, The Hospital for Sick Children, Toronto, ON, Canada; Division of Urology, Department of Surgery, University of Toronto, Toronto, ON, Canada. Electronic address:

Background: Artificial intelligence (AI) and machine learning (ML) methods are increasingly being applied in pediatric urology across a growing number of settings, with more extensive databases and wider interest for use in clinical practice. More than 30 ML models have been published in the pediatric urology literature, but many lack items required by contemporary reporting frameworks to be high quality. For example, most studies lack multi-institution validation, validation over time, and validation within the clinical environment, resulting in a large discrepancy between the number of models developed versus the number of models deployed in a clinical setting, a phenomenon known as the AI chasm.
