Investigating associations between birth order and autism diagnostic phenotypes

Birth order effects have been linked to variability in intelligence, educational attainment and sexual orientation. First- and later-born children have been linked to an increased likelihood of an Autism Spectrum Disorder (ASD) diagnosis, with a smaller body of evidence implicating decreases in cognitive functioning with increased birth order.

Content Validation of Clinician-Reported Items for a Severity Measure for CDKL5 Deficiency Disorder

CDKL5 deficiency disorder (CDD) results in early-onset seizures and severe developmental impairments. A CDD clinical severity assessment (CCSA) was previously developed with clinician and parent-report items to capture information on a range of domains.

Sleep-disordered breathing in Australian children with Prader-Willi syndrome following initiation of growth hormone therapy

In children with Prader-Willi syndrome (PWS), growth hormone (GH) improves height and body composition; however, may be associated with worsening sleep-disordered breathing (SDB). Some studies have reported less SDB after GH initiation, but follow-up with polysomnography is still advised in most clinical guidelines.

The longitudinal relationship between BOLD signal variability changes and white matter maturation during early childhood

Intra-individual transient temporal fluctuations in brain signal, as measured by fMRI blood oxygenation level dependent (BOLD) variability, is increasingly considered an important signal rather than measurement noise.

The Rett Syndrome Gross Motor Scale–Dutch Version (RSGMS-NL) Can Reliably Assess Gross Motor Skills in Dutch Individuals with Rett Syndrome

The Rett Syndrome Gross Motor Scale (RSGMS) is an observational measurement, assessing gross motor skills in individuals with Rett syndrome. A Dutch version is lacking. The current study aims to translate and cross-culturally adapt the original RSMGS to Dutch and assess its inter-rater and intra-rater reliability.

The International Collaboration for Autism Registry Epidemiology (iCARE): Multinational Registry-Based Investigations of Autism Risk Factors and Trends

iCARE provides a unique, unprecedented resource in autism research that will significantly enhance the ability to detect environmental and genetic...

Resourceful and creative methods are necessary to research rare disorders

Our investigation used the infrastructure of InterRett, established in 2002 with dual aims of encour- aging international collaboration and ascertaining the...

Dental admissions in children under two years - A total-population investigation

This paper describes dental and oral cavity admissions and associated factors in children under two years of age using total-population databases.

Neonatal outcomes after preterm birth by mothers' health insurance status at birth: a retrospective cohort study

Publicly insured women usually have a different demographic background to privately insured women, which is related to poor neonatal outcomes after birth.

Hospitalisation rates for children with intellectual disability or autism born in Western Australia 1983-1999: A population-based cohort study

ID and/or ASD were found to be associated with an increased risk of hospitalisation compared with the remainder of the population.
