Antimicrobial Resistance in Enterobacterales, Acinetobacter spp. and Pseudomonas aeruginosa Isolates From Bloodstream Infections in Australian Children, 2013–2021Gram-negative bloodstream infections are associated with significant morbidity and mortality in children. Increasing antimicrobial resistance (AMR) is reported globally, yet efforts to track pediatric AMR at a national level over time are lacking.

Otitis media at 6-monthly assessments of Australian First Nations children between ages 12–36 months: Findings from two randomised controlled trials of combined pneumococcal conjugate vaccinesIn remote communities of northern Australia, First Nations children with hearing loss are disproportionately at risk of poor school readiness and performance compared to their peers with no hearing loss. The aim of this trial is to prevent early childhood persisting otitis media (OM), associated hearing loss and developmental delay.

Postinfectious Acute Cerebellar Syndromes in Children: A Nationally Ascertained Case Series From Australia 2013–2018Postinfectious acute cerebellar syndromes show a wide spectrum of acute severity and can occur with acute febrile illness or vaccine receipt. Varicella has historically been the most common cause, associated with up to 25% of cases in large cohorts. This study aimed to describe the spectrum of syndromes in a setting with high varicella vaccine coverage.

Molecular Methodologies for Improved Polymicrobial Sepsis DiagnosisPolymicrobial sepsis is associated with worse patient outcomes than monomicrobial sepsis. Routinely used culture-dependent microbiological diagnostic techniques have low sensitivity, often leading to missed identification of all causative organisms.

Meningococcal serotype W septic arthritis: Case series in childrenThe epidemiology of invasive meningococcal disease has changed over the last decade and there has been an increase in cases caused by serogroup W135, particularly in Indigenous children. Extra‐meningeal and atypical presentations are associated with serogroup W and may delay diagnosis and therefore appropriate treatment. Public and clinician awareness are essential in facilitating effective new vaccine schedule implementation.

Zika Virus Changes Methylation of Genes Involved in Immune Response and Neural Development in Brazilian Babies Born With Congenital MicrocephalyThe recent increase in babies born with brain and eye malformations in Brazil is associated with Zika virus (ZIKV) infection in utero. ZIKV alters host DNA methylation in vitro. Using genome-wide DNA methylation profiling we compared 18 babies born with congenital ZIKV microcephaly with 20 controls. We found ZIKV-associated alteration of host methylation patterns, notably at RABGAP1L which is important in brain development, at viral host immunity genes MX1 and ISG15, and in an epigenetic module containing the causal microcephaly gene MCPH1. Our data support the hypothesis that clinical signs of congenital ZIKV are associated with changes in DNA methylation.

Impact of covid-19 restrictions on western Australian children’s physical activity and screen timePhysical activity is essential for children’s healthy development, yet COVID-19 physical distancing restrictions such as school closures and staying at home, playground closures, and the cancelling of organised community sport have dramatically altered children’s opportunities to be physically active. This study describes changes in levels of physical activity and screen time from February 2020 (i.e., before COVID-19 restrictions were introduced in Western Australia) to May 2020 (i.e., when COVID-19 restrictions were in place). Parents of children aged 5 to 9 years from Western Australia were eligible to participate and recruited through convenience sampling.

Increasing vaccine acceptance using evidence-based approaches and policies: Insights from research on behavioural and social determinants presented at the 7th Annual Vaccine Acceptance MeetingIn 2019, the World Health Organization (WHO) flagged vaccine hesitancy as one of the top 10 threats to global health. The drivers of and barriers to under-vaccination include logistics (access to and awareness of affordable vaccines), as well as a complex mix of psychological, social, political, and cultural factors.

The politics of picking: Selective vaccinators and population-level policyPublic health systems face tensions between individuals and the collective. Parents who selectively vaccinate demonstrate this tension
