A controlled human infection model of Streptococcus pyogenes pharyngitis (CHIVAS-M75): an observational, dose-finding study

Streptococcus pyogenes is a leading cause of infection-related morbidity and mortality. A reinvigorated vaccine development effort calls for new clinically relevant human S pyogenes experimental infection models to support proof of concept evaluation of candidate vaccines. We describe the initial Controlled Human Infection for Vaccination Against S pyogenes (CHIVAS-M75) study, in which we aimed to identify a dose of emm75 S pyogenes that causes acute pharyngitis in at least 60% of volunteers when applied to the pharynx by swab.

The misnomer of ‘high functioning autism’: Intelligence is an imprecise predictor of functional abilities at diagnosis

We argue that 'high functioning autism' is an inaccurate clinical descriptor when based solely on intelligence quotient demarcations

Whole genome sequencing reveals extensive community-level transmission of group A Streptococcus in remote communities

There was evidence of extensive transmission of group A Streptococcus both within households and across the community

The inequitable burden of group A streptococcal diseases in Indigenous Australians

Given the ongoing mortality and morbidity from GAS infections, we must address more effectively the treatment and prevention of GAS impetigo and pharyngitis

Standardising and assessing digital images for use in clinical trials: A practical, reproducible method that blinds the assessor to treatment allocation

We describe the development and evaluation of a protocol for digital image collection by the non-professional photographer in a remote setting research trial

Prevalence of and risk factors for human rhinovirus infection in healthy aboriginal and non-aboriginal western australian children

Human rhinovirus (HRV) species C (HRV-C) have been associated with frequent and severe acute lower respiratory infections and asthma in hospitalized children.

Reduction in disparity for pneumonia hospitalisations between Australian indigenous and non-Indigenous children

In the 1990s pneumonia hospitalisation rates in Western Australia (WA) were 13 times higher in Indigenous children than in non-Indigenous children...

Challenges and insights in self-swab surveillance for asymptomatic Streptococcus pyogenes carriage

Asymptomatic carriage of Streptococcus pyogenes (Strep A) may contribute to transmission, yet its role remains poorly understood and evidence on optimal detection methods is limited. While self-collected throat swabs are used in infectious disease surveillance, their value for identifying asymptomatic Strep A carriage in adults is uncertain. This pilot prospective cohort study, conducted at a Perth medical research institute between August and October 2024, assessed feasibility and acceptability of self-collection, with sensitivity as a secondary objective. 

Trends in incident acute rheumatic fever or rheumatic heart disease in Indigenous youth in Western Australia: a retrospective cohort study

To determine age-specific and age-standardised incidence trends of acute rheumatic fever (ARF) or rheumatic heart disease (RHD) among Indigenous Western Australians aged less than 35 years of age.

Berrembi Jarragboo-Boorroo Wajawoorroo Men'Gawoom Gijam (Gija Healthy Skin Story): Two-Way Learning for Healthy Skin

Remote-living Aboriginal children in Australia contend with higher rates of skin infections than non-Indigenous children. This work was embedded within a stepped-wedge, cluster randomised controlled trial aiming to halve the rate of skin infections in remote Kimberley communities. It outlines and reflects upon the co-development of a health promotion resource in partnership with the East Kimberley community of Warmun, whilst understanding community perceptions of its impact.
