Acute rheumatic fever (ARF) is an autoimmune disorder resulting from Group A Streptococcus (GAS) pharyngitis or impetigo in children and adolescents, which may evolve to rheumatic heart disease (RHD) with persistent cardiac valve damage. RHD causes substantial mortality and morbidity globally, predominantly among socioeconomically disadvantaged populations, with an interplay of social determinants of health and genetic factors determining overall risk. ARF diagnosis is based on a constellation of clinical and laboratory features as defined by the 2015 Jones Criteria, although advances in molecular point-of-care testing and the ongoing search for ARF biomarkers offer the potential to revolutionise diagnostics.

Despite millennia of strong and continuous culture, inadequate housing has profound consequences on the health and wellbeing of Aboriginal and Torres Strait Islander people in Australia. For example, the excessive and inequitable burden of childhood skin infections, rheumatic fever, gastrointestinal disease and ear infections can all be linked to failures in housing policy, funding and maintenance. Aboriginal and Torres Strait Islander communities and peak bodies continue to call for greater community control and investment in housing.

Skin conditions most frequently encountered in paediatric practice include infections, infestations, atopic dermatitis, and acne. Skin of colour refers to skin with increased melanin and darker pigmentation, and reflects global racial and ethnic diversity. Managing skin conditions in skin of colour requires health equity nuance, which is rarely explicitly taught.

Introduction: Reflexivity is crucial for researchers and health professionals working within Aboriginal health. Reflexivity provides a tool for non-Aboriginal researchers to contribute to the broader intention of reframing historical academic positivist paradigms into Indigenous research methodologies (IRM) to privilege Aboriginal voices in knowledge construction and decision-making. This practice requires researchers to transition from safe and familiar research environments into unfamiliar and uncomfortable spaces.

Platform trials have become widely adopted across multiple disease areas over recent years, however, guidelines for operationalising these trials have not kept pace. We outline a series of documents that summarise the statistical components, and implicit processes, of the Staphylococcus aureus Network Adaptive Platform (SNAP) trial to provide an informal template for other researchers and reviewers of platform trials. We briefly summarise the content and role of the core protocol, statistical appendix, domain-specific appendices, simulation report, statistical implementation guides, data safety and monitoring committee (DSMC) reports, and domain-specific statistical analysis plans and final reports, and a transparent governance structure that ensures separate blinded and unblinded statistical teams.

Recent interest in the diverse ecosystem of bacteria, fungi, parasites, and viruses that make up the skin microbiome has led to several studies investigating the microbiome in healthy skin and in a variety of dermatological conditions. An imbalance of the normal skin flora can cause some skin diseases, and current culture techniques are often unable to detect a microorganism to further our understanding of the clinical-microbiological correlates of disease and dysbiosis. Atopic dermatitis and rosacea are presentations that GPs often manage that may have an infective or microbiological component and can be challenging to treat.

Background: Children spend almost one-third of their waking hours at school. Streptococcus pyogenes (Strep A) is a common childhood bacterial infection that can progress to causing serious disease. We aimed to detect Strep A in classrooms by using environmental settle plates and swabbing of high-touch surfaces in two remote schools in the Kimberley, Western Australia.

Background: Healthy skin is important for maintaining overall physical and cultural health and wellbeing. However, remote-living Australian Aboriginal children contend with disproportionally high rates of (Strep A) infected impetigo. The SToP Trial was a large stepped-wedge cluster randomised trial of See, Treat, and Prevent (SToP) skin health activities implemented between 2019 and 2022 in the Kimberley region of Western Australia, during which a decrease in impetigo was observed.

Purpose: Despite the volume of accumulating knowledge from prospective Aboriginal cohort studies, longitudinal data describing developmental trajectories in health and well-being is limited. The linkage of child and carer cohorts from a historical cross-sectional survey with longitudinal health-service and social-service administrative data has created a unique and powerful data resource that underpins the Western Australian Aboriginal Child Health Survey (WAACHS) linked data study. This study aims to provide evidence-based information to Aboriginal communities across Western Australia, governments and non-government agencies on the heterogeneous life trajectories of Aboriginal children and families.

Article Synopsis
  • - Group A Streptococcus (Strep A) skin infections, like impetigo, can lead to serious conditions such as acute rheumatic fever (ARF) and rheumatic heart disease (RHD), particularly in Indigenous communities where these rates are significantly higher.
  • - Strep A can spread through three key ways: direct skin contact, surface contamination, and airborne transmission, highlighting the importance of addressing these pathways.
  • - The study suggests various household-level initiatives to reduce Strep A transmission, such as improving washing facilities, enhancing yard space for better social distancing, and increasing home ventilation, with an interactive tool developed to evaluate these initiatives' costs and effectiveness.

Article Synopsis
  • - The study aimed to understand the transmission of Streptococcus A (Strep A) in a controlled environment through the Controlled Human Infection with Penicillin for (CHIPS) trial, where participants were intentionally infected with the emm75 strain.
  • - Researchers used three methods to investigate transmission: agar settle plates for droplet or airborne spread, measuring how far droplets travel during conversation, and swabbing high-contact surfaces for the presence of Strep A.
  • - Out of 60 participants in the CHIPS trial, only one instance of droplet transmission was detected, with no evidence of airborne spread or contamination on surfaces, suggesting minimal transmission in this controlled setting but highlighting the need for further research in real-world conditions.
