A 40-year-old man with a medical history of hepatitis B presented with abdominal distention and leg swelling. A computed tomography scan of the abdomen revealed cirrhosis and a large mass extending from the liver into the inferior vena cava and extending into the right atrium. A transthoracic echocardiogram revealed a large right atrial mass extending from the inferior vena cava with possible attachment to the interatrial septum.

Background: With advances in acute stroke care and an ageing population, the number of survivors of stroke is increasing. It is important that healthcare providers ensure patients have adequate information after a stroke-related hospitalisation.
Objective: Drowning is a leading cause of injury-related death in the pediatric and adolescent population. This epidemiologic study describes the trends in emergency department (ED) visits for pediatric drowning injury in North Carolina and the impact of the coronavirus disease 2019 (COVID-19) pandemic on incidence rate.
Methods: Data were obtained using the North Carolina Disease Event Tracking and Epidemiologic Collection Tool, a public health surveillance system, to identify ED visits for drowning injury from 2016 to 2022.
Background: Firearm violence is a significant public health issue. However, it is unclear if there is an association between the Social Vulnerability Index (SVI) and the intent of both fatal and nonfatal firearm injuries, and if these associations are modified by community race and ethnic composition. This study examines the association between community-level social vulnerability and firearm injury incidence in North Carolina (NC) using 2021-2022 emergency medical services (EMS) data.

- Bacteria use a structure called a flagellar filament, made of many subunits, to swim, but it's unclear how they control its length.
- Deleting certain genes in polar flagellated bacteria resulted in longer flagellar filaments, suggesting that the FlaG protein helps regulate filament length by interfering with another protein, FliS, in the secretion system.
- Both flagellar filaments and injectisome systems appear to have evolved similar protein mechanisms to control the secretion of crucial components, highlighting a convergence in bacterial adaptation strategies.
