ATFS-1 counteracts mitochondrial DNA damage by promoting repair over transcriptionThe ability to balance conflicting functional demands is critical for ensuring organismal survival. The transcription and repair of the mitochondrial genome requires separate enzymatic activities that can sterically compete, suggesting a life-long trade-off between these two processes.

Airway macrophages display decreased expression of receptors mediating and regulating scavenging in early cystic fibrosis lung diseaseCystic fibrosis (CF) airway disease is characterized by chronic inflammation, featuring neutrophil influx to the lumen. Airway macrophages (AMs) can promote both inflammation and resolution, and are thus critical to maintaining and restoring homeostasis. CF AM functions, specifically scavenging activity and resolution of inflammation, have been shown to be impaired, yet underlying processes remain unknown.

Determination of Tr1 cell populations correlating with distinct activation states in acute IAV infectionType I regulatory (Tr1) cells are defined as FOXP3-IL-10-secreting clusters of differentiation (CD4+) T cells that contribute to immune suppression and typically express the markers LAG-3 and CD49b and other co-inhibitory receptors. These cells have not been studied in detail in the context of the resolution of acute infection in the lung.

Epidemiology of soil-transmitted helminths using quantitative PCR and risk factors for hookworm and Necator americanus infection in school children in Dak Lak province, VietnamSoil-transmitted helminth (STH) infection is driven by a complex interaction of demographic, socioeconomic and behavioural factors, including those related to water, sanitation and hygiene (WASH). Epidemiological studies that measure both infection and potential risk factors associated with infection help to understand the drivers of transmission in a population and therefore can provide information to optimise STH control programmes.

Development of a sustained release implant of benzathine penicillin G for secondary prophylaxis of rheumatic heart diseaseRegular intramuscular (i.m.) benzathine penicillin G (BPG) injections have been the cornerstone of rheumatic heart disease (RHD) secondary prophylaxis since the 1950s. Patient adherence to IM BPG is poor, largely due to pain, the need for regular injections every 3-4 weeks and health sector delivery challenges in resource-limited settings. There is an urgent need for new approaches for secondary prophylaxis, such as an implant which could provide sustained penicillin concentrations for more than 6 months.

The evidence that rheumatic heart disease control programs in Australia are making an impactRheumatic heart disease (RHD) comprises heart-valve damage caused by acute rheumatic fever (ARF). The Australian Government Rheumatic Fever Strategy funds RHD Control Programs to support detection and management of ARF and RHD. We assessed epidemiological changes during the years of RHD Control Program operation.

Prevalence of tracheobronchomalacia is higher than previously reported in children with cystic fibrosisTracheobronchomalacia (TBM) is estimated to be present in 1 in 2100 children. Previous reports suggest the prevalence is higher in children with cystic fibrosis (CF). This has clinical implications with potential to influence airway clearance and lung health.

Effects of a positive education programme on secondary school students’ mental health and wellbeing; challenges of the school contextPrevious research has demonstrated wellbeing benefits for positive education programmes (PEPs) facilitated by clinicians or experts or outside the school context. The current study explored the effects of a Year 10 PEP led by teachers trained in positive education and embedded within the Australian secondary school context.

Impact of vascular screening interventions on perceived threat, efficacy beliefs and behavioural intentions: a systematic narrative reviewHealth-related behaviours contribute to the global burden of cardiovascular disease (CVD). Cardiovascular imaging can be used to screen asymptomatic individuals for increased risk of CVD to enable earlier interventions to promote health-related behaviours to prevent or reduce CVD risk.
