Streptococcus pyogenes, or group A Streptococcus (GAS), infections contribute to a high burden of disease in Aboriginal Australians, causing skin infections and immune sequelae such as rheumatic heart disease. Controlling skin infections in these populations has proven difficult, with transmission dynamics being poorly understood. We aimed to identify the relative contributions of impetigo and asymptomatic throat carriage to GAS transmission.
The impact of mitral regurgitation from pediatric rheumatic heart disease and its effect on left ventricular remodeling and function following surgical intervention is uncertain. The objective is to explore the impact of mitral valve surgeries on myocardial mechanics, remodeling and function and identify pre-operative predictors of post-operative dysfunction which may contribute to the optimal timing of intervention.

The spectrum of diseases caused by Streptococcus pyogenes (Strep A) ranges from superficial to serious life-threatening invasive infections. We conducted a scoping review of published articles between 1980 and 2021 to synthesize evidence of state transitions across the Strep A disease spectrum. We identified 175 articles reporting 262 distinct observations of Strep A disease state transitions.
Although entirely preventable, rheumatic heart disease, a disease of poverty and social disadvantage resulting in high morbidity and mortality, remains an ever-present burden in low-income and middle-income countries and rural, remote, marginalised and disenfranchised populations within high-income countries.
Secondary prevention of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) involves continuous antimicrobial prophylaxis among affected individuals and is recognised as a cornerstone of public health programmes that address these conditions. However, several important scientific issues around the secondary prevention paradigm remain unresolved.

Acute rheumatic fever (ARF), a serious inflammatory condition, often leads to rheumatic heart disease. Between 2011 and 2016, Aotearoa New Zealand implemented a rheumatic fever prevention programme to reduce high rates of ARF through improved community access to timely diagnosis and early treatment of group A streptococcal pharyngitis, which has been shown to prevent subsequent ARF.
To determine the ability to accurately diagnose acute rheumatic fever given the resources available at three levels of the Ugandan healthcare system.
To determine population-based rates of non-fatal complications of rheumatic heart disease (RHD).
