Social motivation is posited as a key factor in the expression of the autism phenotype. However, lack of precision in both conceptualization and measurement has impeded a thorough understanding of its diverse presentation and associated outcomes. This study addresses this gap by identifying subgroups of autism characterized by deficits in distinct facets of social motivation, relative to normative benchmarks.
Malaria remains a leading cause of illness and death globally, with countries in sub-Saharan Africa bearing a disproportionate burden. Global high-resolution maps of malaria prevalence, incidence, and mortality are crucial for tracking spatially heterogeneous progress against the disease and to inform strategic malaria control efforts. We present the latest such maps, the first since 2019, which cover the years 2000–22. The maps are accompanied by administrative-level summaries and include estimated COVID-19 pandemic-related impacts on malaria burden.
The in-vivo plasma concentration of penicillin needed to prevent Streptococcus pyogenes pharyngitis, recurrent acute rheumatic fever, and progressive rheumatic heart disease is not known. We used a human challenge model to assess the minimum penicillin concentration required to prevent streptococcal pharyngitis.
Appropriate support for the health of children with an intellectual disability by parents and healthcare professionals is pivotal, given the high risk of chronic conditions. However, there is limited research that has collected important insights from parents on their learnings for supporting their child's evolving healthcare needs.
Sleep problems occur in up to 20%-45% of adolescents. This systematic review and meta-analysis examined the effectiveness of digital sleep interventions, based on cognitive behavioural therapy for insomnia, for adolescents with insomnia symptoms. The objective was to synthesise and quantify, through meta-analyses, changes in sleep following completion of a digital sleep-based intervention.
Psychological prevention programmes delivered in schools may reduce symptoms of depression. However, high-quality, large-scale trials are lacking.
Natural outdoor environments such as green and blue spaces have increasingly been seen as key health and wellbeing determinants for adults. However, it is unclear if these effects are seen in young children. We examined the associations between access to natural green and blue space and young children's socioemotional development.
To examine researchers' reports of adherence to ethical principles in their most recent research project, including factors associated with higher self-reported adherence, and perceptions of how research conduct could be improved.
Fuelled by the tobacco industry, commercial tobacco use is a major cause of preventable morbidity and mortality among Aboriginal and Torres Strait Islander peoples. Preventing adolescent smoking initiation is critical to reducing uptake. Understanding individual, social, and environmental factors that are protective against smoking can inform prevention strategies.
To examine self-reported practices for obtaining ethics approval and reflections on ethics application processes among researchers who have conducted Aboriginal and Torres Strait Islander health and medical research.
