Purpose: The use of intramedullary fixation of AO type 31-A1 fractures is rising, despite evidence of non-superiority when compared with extramedullary fixation. The aim of this study was to evaluate mobility and living status for extramedullary fixation (EMF) versus intramedullary fixation (IMF) in Dutch hospitals during the initial hospital stay and until three-months after trauma.

Methods: Data on patient characteristics, mobility, living status, complications, reoperation, and mortality were extracted from the Dutch Hip Fracture Audit Indicator Taskforce.

In contrast to adult mammalian hearts, the adult zebrafish heart efficiently replaces cardiomyocytes lost after injury. Here we reveal shared and species-specific injury response pathways and a correlation between Hmga1, an architectural non-histone protein, and regenerative capacity, as Hmga1 is required and sufficient to induce cardiomyocyte proliferation and required for heart regeneration. In addition, Hmga1 was shown to reactivate developmentally silenced genes, likely through modulation of H3K27me3 levels, poising them for a pro-regenerative gene program.

Background: The terrible triad injury involves an ulnohumeral dislocation, radial head fracture, and coronoid process fracture. According to traditional teaching, these injuries are strongly associated with anterolateral coronoid tip fractures and can be addressed via a lateral approach to the elbow. However, recent small clinical series suggest that some terrible triad injuries have larger coronoid fractures involving the anteromedial facet.

Objective: MRI of the hands is valuable for risk-stratification in patients with arthralgia at-risk for developing rheumatoid arthritis (RA). Contrast-enhanced MRI is considered standard for assessment of RA, but has practical disadvantages. It also shows inflammation-like features in the general population, especially at older age, which should be considered in image interpretation.

Robust advancements in clinical treatment of people living with HIV (PLHIV) have resulted in the current "treatment as prevention" strategy: the inability to transmit the virus when it is undetectable. Nevertheless, disclosure within marital relationships remains important to adhere optimally to treatment and further limit transmission in the era of treat-all. Disclosure, however, can have serious social repercussions, particularly for women.
