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.

Measuring cognitive and affective empathy across positive and negative emotions: psychometric properties and measurement invariance of the Perth Empathy Scale

Empathy, a complex and multidimensional construct essential for social functioning and mental health, has been extensively studied in both research and clinical settings. The Perth Empathy Scale (PES), a recently developed self-report measure, assesses cognitive and affective empathy across both positive and negative emotions and is based on the self-other model of empathy. This study aimed to evaluate the psychometric properties of the Persian version of the PES in large Iranian sample.

The National Paediatric Applied Research Translation Initiative (N-PARTI): using implementation science to improve primary care for Australian children with asthma, type 1 diabetes

General practice-based care for Australian children is facing low levels of clinical guideline adherence particularly in three key areas: asthma, type 1 diabetes and antibiotic use. We offer an implementation science-informed position paper, providing a broad overview of how we aim to address this issue.

Analysis of risk factors associated with suicidality in children and adolescents with fetal alcohol spectrum disorder in Western Australia

Individuals with fetal alcohol spectrum disorder (FASD) are at an elevated suicide risk compared with those in the general population. This public health issue warrants further research attention to help inform the development of prevention and intervention efforts. Our study is the first to characterize suicidality (i.e., suicidal ideation/suicide attempt) and explore associated risk factors in young individuals with FASD within the Australian context.

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.

Acceptability and Implementation Challenges of Benzathine Penicillin G Secondary Prophylaxis for Rheumatic Heart Disease in Ethiopia: A Qualitative Study

Monthly intramuscular injections of benzathine penicillin G (BPG) remain the cornerstone of secondary prophylaxis for acute rheumatic fever and rheumatic heart disease (RHD). The barriers to successful delivery of BPG may be patient- or service-delivery-dependent.

Examining the overlap in lymphatic filariasis prevalence and malaria insecticide-treated net access-use in endemic Africa

Eradication and elimination strategies for lymphatic filariasis (LF) primarily rely on multiple rounds of annual mass drug administration (MDA), but also may benefit from vector control interventions conducted by malaria vector control programs. We aim to examine the overlap in LF prevalence and malaria vector control to identify potential gaps in program coverage. 

Novel GABAAR antagonists target networked gene hubs at the leading-edge in high-grade gliomas

Ion channel activity underlying biological processes that drive high-grade gliomas (HGG) is largely unknown. We aimed to determine the networking of ion channel genes and validate their expression within HGG patient tumors, to identify ion channel-targeting drugs that would inhibit tumor-promoting processes.

Longitudinal observational research study: establishing the Australasian Congenital Cytomegalovirus Register (ACMVR)

Congenital cytomegalovirus (cCMV) is an important cause of long-term childhood disability. In Australia, the identification and treatment practices and the long-term clinical and neurodevelopmental outcomes of children with cCMV are unknown.
