NAADF: Globally Illuminated Voxel Worlds Accelerated with Nested Axis‐Aligned Distance Fields

Computer Graphics Forum, EarlyView.
Abstract Achieving realistic rendering of 3D scenes in real time using path tracing is challenging due to the high sample count required, with ray tracing as the bottleneck. Focusing on voxels as a geometry representation offers significant opportunities for optimizations, especially for tracing the rays, but also for computing the samples.

Bowel Obstruction/Ileus Associated With the Use of Glucagon‐Like Peptide‐1 Receptor Agonists: A Nationwide Database Study

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims The association between glucagon‐like peptide‐1 receptor agonist (GLP‐1RA) use and the development of bowel obstruction/ileus remains unclear, and evidence for specific bowel obstruction/ileus subtypes remains limited. We examined the association between GLP‐1RA use and the incidence of bowel obstruction/ileus subtypes across different ...

Discontinuation of Glucagon‐Like Peptide‐1 Receptor Agonists After Bowel Obstruction or Ileus: A Nationwide, Real‐World, Database Study

Journal of Evidence-Based Medicine, EarlyView.
ABSTRACT Objective Although concerns have been raised that glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) may increase the risk of bowel obstruction or ileus, evidence remains inconclusive. In this context of uncertainty, we examined the frequency and determinants of GLP‐1RA discontinuation after hospitalization for bowel obstruction/ileus ...

Intra‐Abdominal Hemorrhage Following Endoscopic Retrograde Cholangiopancreatography in a Patient with a Cascade Stomach: A Case Report

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Intra‐abdominal hemorrhage is an extremely rare complication of endoscopic retrograde cholangiopancreatography (ERCP). We report a case of intra‐abdominal bleeding that occurred after ERCP for choledocholithiasis with cholangitis in a patient with a cascade stomach.

Clinical Outcomes After Failed Endoscopic Detorsion for Sigmoid Volvulus: A Single‐Center Retrospective Cohort Study

DEN Open, Volume 7, Issue 1, April 2027.
ABSTRACT Objectives Endoscopic detorsion is the first‐line treatment for sigmoid volvulus (SV); however, detorsion is not always successful. We evaluated clinical outcomes after failed endoscopic detorsion and assessed recurrence in patients who achieved clinical success after decompression.
