Longitudinal analysis highlights structural changes in grey- and white-matter within military personnel exposed to blast.

Objective: The purpose of this study was to determine whether gray matter volume and diffusion-based metrics in associated white matter changed in breachers who had neuroimaging performed at two timepoints. A secondary purpose was to compare these changes in a group who had a one-year interval between their imaging timepoints to a group that had a two-year interval between imaging.

Methods: Between timepoints, clusters with significantly different gray matter volume were used as seeds for reconstruction of associated structural networks using diffusion metrics.

Limbic system synaptic dysfunctions associated with prion disease onset.

Misfolding of normal prion protein (PrP) to pathological isoforms (prions) causes prion diseases (PrDs) with clinical manifestations including cognitive decline and mood-related behavioral changes. Cognition and mood are linked to the neurophysiology of the limbic system. Little is known about how the disease affects the synaptic activity in brain parts associated with this system.

The "Climate and Sustainability" working group of the German Society for Rehabilitation Sciences was founded in March 2023. The members represent research, practice, and service providers in rehabilitation. The aim is to make rehabilitation in Germany sustainable and to focus on climate protection and the health consequences of climate change.

Estimating the CTDI with helical acquisitions: Results from a national generalizability study.

Background: While many clinical computed tomography (CT) protocols use helical scanning, the traditional method for measuring the volume CT Dose Index (CTDI) requires modifying the helical protocol to perform a single axial rotation. This modification can present challenges and mismatched settings across various scanner models.

Purpose: This study investigates the generalizability of a helical methodology for estimating CTDI across a diverse range of participants, CT scanner models, and protocol parameters.

From LAL-D to MASLD: Insights into the role of LAL and Kupffer cells in liver inflammation and lipid metabolism.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a prevalent liver pathology worldwide, closely associated with obesity and metabolic disorders. Increasing evidence suggests that macrophages play a crucial role in the development of MASLD. Several human studies have shown an inverse correlation between circulating lysosomal acid lipase (LAL) activity and MASLD.
