The CDKL5 Clinical Severity Assessment is a comprehensive, content-validated measurement tool capturing the diverse challenges of cyclin-dependent kinase-like 5 deficiency disorder, a genetically caused developmental epileptic encephalopathy. The CCSA is divided into clinician-reported and caregiver-reported assessments. The aim of this study was to evaluate the factor structure of these measures through confirmatory factor analysis and evaluate their validity and reliability.
Youth with prenatal alcohol exposure (PAE) are under-recognised in the justice system, warranting improved identification. This study aimed to compare neuropsychological profiles of adolescents, with and without PAE and identify neuropsychological tasks predictive of PAE-group membership. It was hypothesised that participants with PAE would score significantly lower on neuropsychological tests.
To assess potential benefits and direct healthcare cost savings with expansion of an existing childhood influenza immunisation program, we developed a dynamic transmission model for the state of Western Australia, evaluating increasing coverage in children < 5 years and routinely immunising school-aged children.
This population-based study investigated the association of BMI and other predictors with gestational diabetes mellitus among Australian Aboriginal and non-Aboriginal mothers. We conducted a state-wide retrospective cohort study that included all singleton births in Western Australia between 2012 and 2015 using population health datasets linked by the Western Australian Data Linkage Branch.
More than 1 in 5 children experience neglect, exposing them to several adverse consequences. Children with intellectual disability experience additional neglect related challenges. Public perceptions significantly influence the identification, intervention, and prevention of child neglect.
CDKL5 deficiency disorder (CDD) results in early-onset epilepsy and lifelong cognitive and motor impairments. With no validated measure for communication in CDD, this study evaluated the psychometric properties of the Communication and Symbolic Behavior Scales-Developmental Profile Infant Toddler Checklist.
Children in Papua New Guinea (PNG) are at high risk of pneumococcal infections. We investigated pneumococcal carriage rates, serotype distribution, and antimicrobial susceptibility in PNG children after vaccination with 10-valent or 13-valent pneumococcal conjugate vaccines (PCV10; PCV13).
Siblings of individuals with neurodevelopmental conditions (NDCs) have greater incidence of neuropsychiatric diagnoses and neurocognitive difficulties compared to siblings of persons without NDCs. Despite suicidality being labelled a global health crisis (WHO, 2014) and NDC siblings experiencing risk factors implicated in suicidality, no previous studies examined suicidality amongst adolescent and young adult siblings of persons with NDCs. Our study aimed to bridge this gap.
