Although uncommon, invasive meningococcal disease (IMD) results in death in 5%-10% of cases in healthy children and adolescents. This study aimed to examine demographics, clinical presentation, treatment and outcomes of Australian children hospitalized with IMD during the introduction of the meningococcal vaccine program, overall and by serogroup/disease severity.
Rheumatic heart disease, a major cause of morbidity and mortality in low- and middle-income countries, results from acute rheumatic fever (ARF), for which no diagnostic test currently exists. The ARF Diagnosis Collaborative Network (ARC Network) was established to address this gap by recruiting a rigorously phenotyped, globally representative cohort of children and adolescents with ARF and controls to support biomarker discovery.
Group A Streptococcal (GAS) pharyngitis is an important precursor infection to severe complications including rheumatic fever and invasive GAS. Rapid molecular point of care testing (POCT) for GAS infection has advantages over traditional microbiological culture, especially in settings with limited or absent laboratory infrastructure and where GAS complications predominate.
Congenital cytomegalovirus (cCMV) is a common infection at birth with the potential to cause significant and permanent morbidity, most commonly hearing loss. Targeted cCMV testing programmes use hearing loss as an indicator of an infant being at high risk of the infection and thereby can 'target' or focus testing on those at greatest risk. Australian and International guidelines recommend that high-risk infants be offered cCMV testing, yet across Australia, a formal testing system does not exist.
Controlled human infection (CHI) models can provide insights into transmission of pathogens such as Streptococcus pyogenes (Strep A). As part of the Controlled Human Infection with Penicillin for Streptococcus pyogenes (CHIPS) trial, we explored the potential for transmission among participants deliberately infected with the Strep A emm75 strain.
Staphylococcus 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.
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 to privilege Aboriginal voices in knowledge construction and decision-making.
