The use of point-of-care ultrasound in Tshwane public and private sector emergency units.

Background: The use of point-of-care ultrasound (POCUS) is an essential skill in the practice of emergency medicine (EM), with benefit to patient care by improving diagnostic accuracy. Despite this, there exists little data evaluating the use of POCUS in South African emergency units (EUs.).

Neuromuscular disease genetics in under-represented populations: increasing data diversity.

Neuromuscular diseases (NMDs) affect ∼15 million people globally. In high income settings DNA-based diagnosis has transformed care pathways and led to gene-specific therapies. However, most affected families are in low-to-middle income countries (LMICs) with limited access to DNA-based diagnosis.

Risky Decision Making Under Stressful Conditions: Men and Women With Smaller Cortisol Elevations Make Riskier Social and Economic Decisions.

Men often make riskier decisions than women across a wide range of real-life behaviors. Whether this sex difference is accentuated, diminished, or stable under stressful conditions is, however, contested in the scientific literature. A critical blind spot lies amid this contestation: Most studies use standardized, laboratory-based, cognitive measures of decision making rather than complex real-life social simulation tasks to assess risk-related behavior.

Major interpersonal violence cases seen in a Pretoria academic hospital over a one-year period, with emphasis on community assault cases.

Introduction: Interpersonal violence cases make up a significant portion of the trauma cases seen in emergency centres in South Africa. Community assaults are extremely violent attacks on suspected perpetrators by members of the community aimed at inflicting serious injury. The aim of this study was to profile the major interpersonal violence cases at Kalafong Hospital with emphasis on the community assaults and how this group compares with non- community assaults regarding demographics, surgical intervention and mortality.

Elevated Cortisol Leaves Working Memory Unaffected in Both Men and Women.

Activation of the hypothalamic-pituitary-adrenal (HPA) axis (as might occur, for example, when the organism encounters a threat to allostatic balance) leads to the release of cortisol into the bloodstream and, ultimately, to altered neural functioning in particular brain regions (e.g., the prefrontal cortex (PFC)).
