Intramuscular (IM) injection of benzathine benzylpenicillin G (BPG) forms the cornerstone of acute rheumatic fever (ARF) and rheumatic heart disease (RHD) secondary prophylaxis. BPG is available as either a low-cost powdered formulation or a costlier pre-filled suspension. Most of the global RHD burden lies in low- and middle-income countries, which rely on the powdered formulation.
Convalscent plasma (CP) was identified as a potential therapy for COVID-19 available early in the pandemic.
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.
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.
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.
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.
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.
Staphylococcus 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.
The 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.
