Primary blast traumatic brain injury (bTBI) accounts for a significant proportion of wartime trauma. Previous studies have demonstrated direct brain injury by blast waves, but the effect of the location of the blast epicenter on the skull with regard to brain injury remains poorly characterized. In order to investigate the role of the blast epicenter location, we modified a previously established rodent model of cranium-only bTBI to evaluate two specific blast foci: a rostrally focused blast centered on bregma (B-bTBI), which excluded the foramen magnum region, and a caudally focused blast centered on the occipital crest, which included the foramen magnum region (FM-bTBI). At all blast overpressures studied (668-1880 kPa), rats subjected to FM-bTBI demonstrated strikingly higher mortality, increased durations of both apnea and hypoxia, and increased severity of convexity subdural hematomas, than rats subjected to B-bTBI. Together, these data suggest a unique role for the foramen magnum region in mortality and brain injury following blast exposure, and emphasize the importance of the choice of blast focus location in experimental models of bTBI.

Development and external validation of a machine learning model for brain injury in pediatric patients on extracorporeal membrane oxygenation.
Crit Care
January 2025
Department of Pediatric, West China Second University Hospital, Sichuan University, Chengdu, China.
Background: Patients supported by extracorporeal membrane oxygenation (ECMO) are at a high risk of brain injury, contributing to significant morbidity and mortality. This study aimed to employ machine learning (ML) techniques to predict brain injury in pediatric patients ECMO and identify key variables for future research.
Methods: Data from pediatric patients undergoing ECMO were collected from the Chinese Society of Extracorporeal Life Support (CSECLS) registry database and local hospitals.

Traumatic brain injury (TBI) is one of the most traumatizing and poses serious health risks to people's bodies due to its unique pathophysiological characteristics. The investigations on the pathological mechanism and valid interventions of TBI have attracted widespread attention worldwide. With bio-mimic mechanic cues, the dynamic hydrogels with dynamic stiffness changes or reversible crosslinking have been suggested to construct the in vitro disease models or novel therapeutic agents for TBI.

Department of Brain and Spinal Cord Injury, Neuroscience Centre, Copenhagen University Hospital - Rigshospitalet, Copenhagen, Denmark.
Background: The harm-benefit balance for early out-of-bed mobilisation of patients with severe acquired brain injury (ABI) in neurointensive care units (neuro-ICUs) is unclear, and there are no clinical guidelines. This study aimed to survey the current clinical practice and perceptions among clinicians involved in first out-of-bed mobilisation in Scandinavian neuro-ICUs.
Methods: This was a cross-sectional, anonymous, web-based survey; the reporting follows the recommended CROSS checklist.
