Genotype and sleep independently predict mental health in Rett syndrome: An observational studyRett syndrome is a genetically caused neurodevelopmental disorder associated with severe impairments and complex comorbidities. This study examined predictors of anxiety and depression in Rett syndrome, including genotype.

The Effect of Mineral Trioxide Aggregate Obturation Levels on the Outcome of Endodontic Retreatment: An Observational StudyNo clinical studies have examined the effect of mineral trioxide aggregate (MTA) obturation levels on the outcome of endodontic retreatment. This retrospective study examined treatment outcomes in three cohorts that compared overfilling, flush filling, and underfilling after orthograde retreatment using MTA.

Cerebral palsy: EpidemiologyCerebral palsy (CP) is a lifelong physical disability, resulting from maldevelopment or damage to the developing brain. All children with CP have a disorder of movement and posture, but this is often accompanied by disorders of intellect, sensation, behaviour and epilepsy. Long-standing CP registers and surveillance systems estimate the prevalence of CP as approximately 2 per 1000 live births; however variations are seen over time and in different regions of the world.

Early mortality among aboriginal and non-Aboriginal women who had a preterm birth in Western Australia: A population-based cohort studyHaving a preterm (<37 weeks' gestation) birth may increase a woman's risk of early mortality. Aboriginal and Torres Strait Islander women have higher preterm birth and mortality rates compared with other Australian women.

Factors influencing the attainment of major motor milestones in CDKL5 deficiency disorderThis study investigated the influence of factors at birth and in infancy on the likelihood of achieving major motor milestones in CDKL5 Deficiency Disorder (CDD). Data on 350 individuals with a pathogenic CDKL5 variant was sourced from the International CDKL5 Disorder Database.

Functioning, participation, and quality of life in children with intellectual disability: an observational studyTo investigate associations between functioning, community participation, and quality of life (QoL) and identify whether participation mediates the effects of functioning on QoL.

Development of an International Database for a Rare Genetic Disorder: The MECP2 Duplication Database (MDBase)The natural history of MECP2 duplication syndrome (MDS), a rare X-linked neurodevelopmental disorder with an estimated birth prevalence of 1/150,000 live births, is poorly understood due to a lack of clinical data collected for research. Such information is critical to the understanding of disease progression, therapeutic endpoints and outcome measures for clinical trials, as well as the development of therapies and orphan products.

Epidemiology of Rare Craniofacial Anomalies: Retrospective Western Australian Population Data Linkage StudyWe aimed to describe birth prevalence of rare craniofacial anomalies and associations with antenatal and perinatal factors. All live and stillbirths in Western Australia between 1980 and 2010 were identified from the Western Australian Birth Registrations and the Midwives Notification System (also provides information on antenatal and perinatal factors).

The contributions of fetal growth restriction and gestational age to developmental outcomes at 12 months of age: A cohort studyDevelopmental assessment of infants with fetal growth restriction was mostly comparable to those born without fetal growth restriction at 12 months
