START: Towards a diagnostic test for rheumatic feverIn this study we will use new methods to comprehensively test immune responses in blood samples from people with ARF (diagnosed using the Jones Criteria) and healthy volunteers at Royal Darwin and from Auckland Hospital, New Zealand, to find any unique signature that reliably identifies ARF.

Research opportunities for the primordial prevention of rheumatic fever and rheumatic heart disease - streptococcal vaccine development: a national heart, lung and blood institute workshop reportStreptococcus pyogenes, also known as group A streptococcus (StrepA), is a bacterium that causes a range of human diseases, including pharyngitis, impetigo, invasive infections, and post-infection immune sequelae such as rheumatic fever and rheumatic heart disease. StrepA infections cause some of the highest burden of disease and death in mostly young populations in low-resource settings. Despite decades of effort, there is still no licensed StrepA vaccine, which if developed, could be a cost-effective way to reduce the incidence of disease.

Subcutaneous infusion of high-dose benzathine penicillin G is safe, tolerable, and suitable for less-frequent dosing for rheumatic heart disease secondary prophylaxis: a phase 1 open-label population pharmacokinetic studySince 1955, the recommended strategy for rheumatic heart disease secondary prophylaxis has been benzathine penicillin G injections administered intramuscularly every 4 weeks. Due to dosing frequency, pain, and programmatic challenges, adherence is suboptimal. It has previously been demonstrated that BPG delivered subcutaneously at a standard dose is safe and tolerable and has favorable pharmacokinetics, setting the scene for improved regimens with less frequent administration.
Research
A pilot study to develop assessment tools for Group A Streptococcus surveillance studiesGroup A Streptococcus (GAS) causes pharyngitis (sore throat) and impetigo (skin sores) GAS pharyngitis triggers rheumatic fever (RF) with epidemiological evidence supporting that GAS impetigo may also trigger RF in Australian Aboriginal children. Understanding the concurrent burden of these superficial GAS infections is critical to RF prevention. This pilot study aimed to trial tools for concurrent surveillance of sore throats and skins sore for contemporary studies of RF pathogenesis including development of a sore throat checklist for Aboriginal families and pharynx photography.

Strengthening health systems to support children with neurodevelopmental disabilities in Fiji—A commentaryLeadership and collaboration has resulted in increased capacity in the Fijian health system to support children with neurodevelopmental disabilities
Research
Subcutaneous administration of benzathine benzylpenicillin G has favourable pharmacokinetic characteristics for the prevention of rheumatic heart disease compared with intramuscular injectionBenzathine penicillin G has been used as monthly deep intramuscular (IM) injections since the 1950s for secondary prevention of acute rheumatic fever and rheumatic heart disease (RHD). Injection frequency and pain are major programmatic barriers for adherence, prompting calls for development of better long-acting penicillin preparations to prevent RHD.
