Psychological distress in three Australian communities living with environmental per- and polyfluoroalkyl substances contaminationEnvironmental chemical contamination is a recognised risk factor for psychological distress, but has been seldom studied in the context of per- and polyfluoroalkyl substances (PFAS) contamination. We examined psychological distress in a cross-sectional study of three Australian communities exposed to PFAS from the historical use of aqueous film-forming foam in firefighting activities, and three comparison communities without environmental contamination.

National brain tumour registry: a new era of research collaboration with ChinaCancer continues to be a leading cause of death globally. However, there remains a significant disparity in the reported incidence of cancer in developed countries, estimated to be 295.3 cases per 100,000 people, compared with only 115.7 in developing countries. Some of the reasons for this variation include lack of robust data collection with limited reporting systems, and insufficient data availability in the registries of these developing nations.

Maternal Pertussis Vaccination, Infant Immunization, and Risk of PertussisFollowing the introduction of jurisdictional maternal pertussis vaccination programs in Australia, we estimated maternal vaccine effectiveness (VE) and whether maternal pertussis vaccination modified the effectiveness of the first 3 primary doses of pertussis-containing vaccines.

How Well Does the EQ-5D-Y-5L Describe Children With Intellectual Disability?: “There's a Lot More to My Child Than That She Can't Wash or Dress Herself.”The EQ-5D-5L is a generic health utility instrument for measuring health-related quality of life (HRQoL), with self-report and proxy report versions for children (EQ-5D-Y-5L). Children with intellectual disability (ID) are a heterogeneous population whose impairments and comorbidities place them at risk of poor HRQoL. This study aimed to describe the content validity and suitability for children with ID of a proxy report version of the EQ-5D-Y-5L as seen by their caregivers.

More than dirt: Sedimentary ancient DNA and Indigenous AustraliaThe rise of sedimentary ancient DNA (sedaDNA) studies has opened new possibilities for studying past environments. This groundbreaking area of genomics uses sediments to identify organisms, even in cases where macroscopic remains no longer exist. Managing this substrate in Indigenous Australian contexts, however, requires special considerations. Sediments and soils are often considered as waste by-products during archaeological and paleontological excavations and are not typically regulated by the same ethics guidelines utilised in mainstream 'western' research paradigms.

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.

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.

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.

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.
