Longitudinal surveillance of group A streptococcal pharyngitis and impetigo in remote Western Australian school children informs acute rheumatic fever prevention

The prevalence of impetigo and pharyngitis - which are both superficial group A streptococcus (GAS) infections that precede acute rheumatic fever - is poorly defined. Guidelines recommend the early diagnosis of both infections to prevent ARF; however, screening to enable the concurrent detection of these infections in high-risk populations has rarely been performed.

Follow-up and Outcomes of Infants Perinatally-exposed to HIV in a Low-prevalence Setting: The Multicenter Children's HIV Exposure Study 2

To investigate the follow-up and outcomes of HIV-exposed infants in a setting of low HIV prevalence. This was a multicenter, retrospective study of live-born infants of women known to be living with HIV, at 9 tertiary pediatric centers in Australia and New Zealand from 2009-2025. Antenatal, perinatal, and postnatal data, and outcomes at clinic visits to 18 months of age were collected, including co-morbidities, development, and HIV results.

Characterising commensal and pathogenic staphylococcal interactions with neonatal and adult blood

The abundant skin commensal, Staphylococcus epidermidis, is the leading cause of late-onset sepsis (LOS) in preterm infants but rarely causes infections in term infants and adults. Staphylococcal virulence mechanisms and the role of the preterm immune responses in driving these life-threatening infections remain poorly understood.

Population pharmacokinetics of penicillin G: insights into increased clearance at low concentrations to guide development of improved long-acting formulations for syphilis

Although benzylpenicillin (penicillin G) is listed by the World Health Organization as an Essential Medicine, dose optimization is a persistent challenge, especially for long-acting intramuscular formulations. Maintaining sustained antibiotic exposure at target concentrations is crucial for secondary chemoprophylaxis of rheumatic heart disease and treatment of syphilis.

Healthy skin for children and young people with skin of colour starts with clinician knowledge and recognition

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.

The Koolungar (Children) Moorditj (Strong) Healthy Skin Project Part I: Conducting First Nations Research in Pediatric Dermatology

Integrating First Nations knowledge systems and Western research methodologies recognizes the strength, experience, and insight of First Nations peoples in addressing health issues in their communities. In research, this includes projects being led by First Nations Elders and peoples, including First Nations researchers in the team, and collecting data in ways that reflect First Nations ways of knowing, being, and doing.

Patient-reported perceptions, experiences and preferences around intravenous and oral antibiotics for the treatment of Staphylococcus aureus bacteremia: a descriptive qualitative study

There is growing evidence to support partial oral antibiotic treatment of severe infections such as Staphylococcus aureus bacteremia, but clinical practice is slow to adopt this paradigm. We know little about how patients with severe infection experience and perceive intravenous and oral antibiotics in terms of quality of life and clinical effectiveness. We performed a qualitative study to elicit patients' views on treatment with intravenous and oral antibiotics, aiming to provide insights that could inform collaborative treatment decision-making.

Yarning with a remote Aboriginal community about the next steps for achieving healthy skin

Skin health is widely recognised as being important for overall good health and well-being, yet the burden of skin infections in remote Aboriginal communities remains high. This project aimed to explore if virtual support for skin health could be a strategy to reduce community barriers to skin health engagement.

“You can't heal yourself in that setting and you wouldn't expect other people in this country to”: Yarning about housing and environmental health in remote Aboriginal communities

Remote Aboriginal communities in Australia are located on traditional lands holding deep cultural significance and meaning for residents. However, systemic inequity rooted in colonisation has driven persistent housing and health disparities, with inadequate environmental health conditions within homes and communities a prominent example.
