The Anticoagulation Dilemma: Concurrent Traumatic Brain Hemorrhage and Cerebral Venous Thrombosis in a Blast Injury Patient

Clinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Blast injuries produce complex multi‐system trauma through primary barotrauma, secondary penetrating projectiles, tertiary displacement forces, and quaternary mechanisms. Among the most challenging complications is the concurrent presentation of traumatic intracranial hemorrhage and cerebral venous sinus thrombosis (CVST), which creates a ...

Foreign body ingestions in children and adolescents: A position paper of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) endoscopy special interest group

Journal of Pediatric Gastroenterology and Nutrition, Volume 83, Issue 3, Page 539-554, September 2026.
Abstract Foreign body (FB) ingestion is a relatively frequent occurrence in the pediatric population with multiple potential sequelae. Appropriate intervention may range from urgent endoscopic retrieval to watchful waiting, with multiple variables influencing the decision.

A Look at Eight Outbursts of Comet 7P/Pons–Winnecke

The Planetary Science Journal
Cometary outbursts may be used as a means to infer the physical processes occurring on cometary nuclei. To that end, we studied eight outbursts of comet 7P/Pons–Winnecke identified between 2021 June 3 and August 31. The data analyzed consisted of optical
