Characterising symptomatic substates in individuals on the psychosis continuum: a hidden Markov modelling approach

To improve early intervention and personalise treatment for individuals early on the psychosis continuum, a greater understanding of symptom dynamics is required. We address this by identifying and evaluating the movement between empirically derived attenuated psychotic symptomatic substates-clusters of symptoms that occur within individuals over time.

Longitudinal Study of Indigenous Children: Adolescent never smoking and associations with individual, social, and environmental factors

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. 

Parsing the heterogeneity of social motivation in autism

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.

Predicting Problem Gambling in Young Men: The Impact of Sports Gambling Frequency and Internalizing Symptoms

Young men aged 18-25 years are at disproportionately increased risk for gambling problems compared to their older or female counterparts. The unique mechanisms that precipitate these problems in this group remain unclear. Data from the largest longitudinal cohort study on Australian men's health (the Ten to Men Study) were used to identify the psychosocial, health-related, and gambling-related behavioral predictors of problem gambling severity in 265 young men aged 18-25 years. Hierarchical multiple ordinal logistic regression analyses found these predictors to explain a moderate proportion of variance in problem gambling severity. 

Mapping residual malaria transmission in Vietnam

Vietnam, as one of the countries in the Greater Mekong Subregion, has committed to eliminating all malaria by 2030. Declining case numbers highlight the country's progress, but challenges including imported cases and pockets of residual transmission remain. To successfully eliminate malaria and to prevent reintroduction of malaria transmission, geostatistical modelling of vulnerability (importation rate) and receptivity (quantified by the reproduction number) of malaria is critical.

ATAGI Targeted Review 2021: the national COVID-19 vaccination program

The overarching goal of the Australian coronavirus disease 2019 (COVID-19) vaccination program has been to protect all people in Australia from the harm caused by the novel coronavirus SARS-CoV-2. This review reflects on the role of the Australian Technical Advisory Group on Immunisation (ATAGI) in the national COVID-19 vaccination program, in terms of the initial programmatic and clinical recommendations in the evolving context of evidence relating to the disease and vaccines, epidemiology, and the program rollout.

Comparing home polysomnography with transcutaneous CO2 monitoring to laboratory polysomnography in children with neuromuscular disorders

Clinical utility of home polysomnography in children with neuromuscular disorders is limited by lack of evidence that sleep-disordered breathing can be reliably identified and inability to diagnose hypoventilation because carbon dioxide is not measured.

Exploring the Experiences of Australian Fathers Who Lead School ‘Dads Groups’

Past research suggests that fathers are underrepresented in traditional parenting and child health promotion programs compared to mothers. One promising method to deliver support is a peer-facilitated approach that enables fathers to connect with their peers. This model has been adopted by several community organisations in Australia. However, limited research evaluates the implementation and impact of these services.

Deciphering IGH rearrangement complexity and detection strategies in acute lymphoblastic leukaemia

Acute lymphoblastic leukaemia is a highly heterogeneous malignancy characterised by various genomic alterations that influence disease progression and therapeutic outcomes. Gene fusions involving the immunoglobulin heavy chain gene represent a complex and diverse category.

Quantifying the impact of contact tracing interview prioritisation strategies on disease transmission: A modelling study

Contact tracing is an important public health measure used to reduce transmission of infectious diseases. Contact tracers typically conduct telephone interviews with cases to identify contacts and direct them to quarantine, with the aim of preventing onward transmission. However, in situations where caseloads exceed the capacity of the public health system, timely interviews may not be feasible for all cases. Here we present a modelling framework for assessing the impact of different case interview prioritisation strategies on disease transmission.
