Since its emergence in 1968, influenza A H3N2 has caused yearly epidemics in temperate regions. While infection confers immunity against antigenically similar strains, new antigenically distinct strains that evade existing immunity regularly emerge ('antigenic drift'). Immunity at the individual level is complex, depending on an individual's lifetime infection history.

Siblings of children with neurodevelopmental conditions have unique experiences and challenges related to their sibling role. Some develop mental health concerns as measured by self-reported surveys or parent report. Few data are available at the population level, owing to difficulties capturing wide-scale health data for siblings. Data linkage is a technique that can facilitate such research. 

Quantifying the extent to which previous infections and vaccinations confer protection against future infection or disease outcomes is critical to managing the transmission and consequences of infectious diseases. We present a general statistical model for predicting the strength of protection conferred by different immunising exposures (numbers, types, and strains of both vaccines and infections), against multiple outcomes of interest, whilst accounting for immune waning. 

Non-suicidal self-injury (NSSI) is particularly common among trans young people. NSSI is most commonly used as an emotion regulation strategy, which may explain the high prevalence of the behavior among trans young people, who often experience unique stressors. In the current study we test an application of the Pantheoretical Framework of Dehumanization, in which transphobic experiences, body surveillance, body dissatisfaction, and gender dysphoria are all theorized to predict NSSI.

Food retail and food service outlets can be part of a chain, or independently operated. Chain food outlets are likely to have the most influence over community food environments but have not been routinely identified in studies which map and monitor access to food, highlighting an important knowledge gap. This study aimed to identify the food retail and food service outlets present within metropolitan Perth, including presence of chain and independent food outlets; and examine differences across local governments. 

Down syndrome, the most common genetic disorder, is caused by the presence of all or part of a third copy of chromosome 21. We identified the top 10 patient and carer research priorities for children with Down syndrome.

Flexible bronchoscopy is the gold standard for difficult airway management. Clinicians are using videolaryngoscopy increasingly because it is perceived to be easier to use with high success rates. We conducted this study to compare the success rates of the two techniques when used after failed direct laryngoscopy in children with difficult tracheal intubations.

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.

Understanding patterns of bacterial carriage and otitis media (OM) microbiology is crucial for assessing vaccine impact and informing policy. The microbiology of OM can vary with geography, time, and interventions like pneumococcal conjugate vaccines (PCVs). We evaluated the microbiology of nasopharyngeal and middle ear effusions in children living in Western Australia, 11 years following the introduction of PCV13.

Body position and movement during sleep is assessed for both clinical and research purposes. A diverse array of both assessment tools and classification systems are used to capture and code sleep biomechanics data.
