Spatiotemporal patterns of influenza in Western AustraliaUnderstanding the geospatial distribution of influenza infection and the risk factors associated with infection clustering can inform targeted preventive interventions. We conducted a geospatial analysis to investigate the spatial patterns and identify drivers of medically attended influenza infection across all age groups in Western Australia.

Early Oral Antibiotic Switch in Staphylococcus aureus Bacteraemia: The Staphylococcus aureus Network Adaptive Platform (SNAP) Trial Early Oral Switch ProtocolStaphylococcus aureus bloodstream infection is traditionally treated with at least 2 weeks of intravenous antibiotics in adults, 3-7 days in children, and often longer for those with complicated disease. The current practice of treating S. aureus bacteremia with prolonged IV antibiotics (rather than oral antibiotics) is based on historical observational research and expert opinion. Prolonged IV antibiotic therapy has significant disadvantages for patients and healthcare systems, and there is growing interest in whether a switch to oral antibiotics following an initial period of IV therapy is a safe alternative for clinically stable patients.

Describing skin health and disease in urban-living Aboriginal children: co-design, development and feasibility testing of the Koolungar Moorditj Healthy Skin pilot projectIndigenous children in colonised nations experience high rates of health disparities linked to historical trauma resulting from displacement and dispossession, as well as ongoing systemic racism. Skin infections and their complications are one such health inequity, with the highest global burden described in remote-living Australian Aboriginal and/or Torres Strait Islander (hereafter respectfully referred to as Aboriginal) children. Yet despite increasing urbanisation, little is known about the skin infection burden for urban-living Aboriginal children.

Clinical and Molecular Epidemiology of an Emerging Panton-Valentine Leukocidin-Positive ST5 Methicillin-Resistant Staphylococcus aureus Clone in Northern AustraliaRecently, we identified a Staphylococcus aureus sequence type 5 (ST5) clone in northern Australia with discrepant trimethoprim-sulfamethoxazole (SXT) susceptibility results. We aimed to identify isolates of this clone using Vitek 2 SXT resistance as a proxy and to compare its epidemiology with those of other circulating S. aureus strains. We collated Vitek 2 susceptibility data for S. aureus isolates collected through our laboratory and conducted a prospective, case-control study comparing clinical, microbiological, epidemiological, and genomic data for subsets of isolates reported as SXT resistant (cases) and SXT susceptible (controls) by Vitek 2.

Optimising detection of thrombosis in paediatric Staphylococcus aureus bacteraemia: A prospective interventional sub-study protocolStaphylococcus aureus bacteraemia (SAB) is the most common cause of sepsis, contributing to paediatric intensive care unit admission in Australia and New Zealand. While deep venous thrombosis (DVT) has been reported in children with invasive S. aureus infections, the actual frequency and possible effects of thrombosis on disease severity and outcome in paediatric SAB remain unknown. Moreover, guidance regarding imaging for paediatric SAB management are poorly defined.

World Society for Pediatric Infectious Diseases calls for action to ensure fair prices for vaccinesThe eradication of smallpox is considered one of the greatest achievements of humankind, thanks to vaccination. The widespread availability of childhood vaccines has substantially reduced childhood morbidity and mortality. Devastating infections, such as polio, have almost disappeared due to vaccination. In 2021, it was estimated that vaccination against ten selected pathogens will have averted 69 million deaths between 2000 and 2030. Increases in vaccine coverage and introduction of additional vaccines should reduce lifetime mortality by 72% in the 2019 birth cohort. However, access to vaccines that prevent life-threatening and disabling infectious diseases remains unequal.

Host-dependent resistance of Group A Streptococcus to sulfamethoxazole mediated by a horizontally-acquired reduced folate transporterDescribed antimicrobial resistance mechanisms enable bacteria to avoid the direct effects of antibiotics and can be monitored by in vitro susceptibility testing and genetic methods. Here we describe a mechanism of sulfamethoxazole resistance that requires a host metabolite for activity.

Pediatric Staphylococcus aureus Bacteremia: Clinical Spectrum and Predictors of Poor OutcomeStaphylococcus aureus is a common cause of bacteremia, yet the epidemiology and predictors of poor outcome remain inadequately defined in childhood. ISAIAH (Invasive Staphylococcus aureus Infections and Hospitalizations in children) is a prospective, cross-sectional study of S. aureus bacteremia in children hospitalized in Australia and New Zealand over 24 months.

The burden of bacterial skin infection, scabies and atopic dermatitis among urban-living Indigenous children in high-income countries: a protocol for a systematic reviewBacterial skin infections and scabies disproportionately affect children in resource-poor countries as well as underprivileged children in high-income countries. Atopic dermatitis is a common childhood dermatosis that predisposes to bacterial skin infection.
