Genomic and Acoustic Biogeography of the Iconic Sulphur-crested Cockatoo Clarifies Species Limits and Patterns of Intraspecific Diversity.

Many highly recognizable species lack genetic data important for conservation due to neglect over their hyperabundance. This likely applies to the Sulfur-crested Cockatoo (Cacatua galerita), one of the world's most iconic parrots. The species is native to Australia, New Guinea, and some surrounding Melanesian islands of the latter.

Parental diagnosis of shunt malfunction in children.

IntroductionEvaluation of shunt for malfunction and blockage is a common neurosurgical clinical scenario in day-to-day paediatric neurosurgery practice. Parental concern for shunt malfunction is normally considered a reliable indication for undertaking further assessment of a child with a shunt. Accuracy of parental diagnosis of shunt malfunction likely is dependent on combination of parental knowledge and patient symptomatology and familiarity of symptoms in relation to previous shunt malfunction symptoms.

Pre-existing parental stress and youth internalizing symptoms predict parent-reported COVID-related stress in military families.

Understanding the extent to which youth and families experienced COVID-related stress requires accounting for prior levels of stress and other associated factors. This is especially important for military families, which experience unique stressors and may be reluctant to seek outside help. In this prospective study, we examined the role of pre-pandemic family factors in predicting parent and youth stress during the COVID-19 pandemic.

Seizures as presentation of shunt malfunction: tertiary paediatric neurosurgery experience.

Aim: Patients with a background of cerebrospinal fluid (CSF)-diverting shunts are frequently investigated for shunt malfunction when presenting with seizures. However, there is very limited evidence in the literature regarding the association of seizures and shunt malfunction. We sought to determine the incidence of shunt malfunction in our cohort of shunted paediatric patients presenting with seizures, and the utility of seizures as a marker of shunt malfunction.
