Pre-Post Intervention to Strengthen and Sustain the Paediatric ESCALATION System (The SPECS): Study ProtocolPromptly recognising changes in an acutely unwell child’s condition is fundamental to prevent tragic outcomes. Western Australian (WA) healthcare facilities used inconsistent and varied paediatric early warning systems. To improve care consistency, a standardised ESCALATION system, inclusive of family involvement and sepsis recognition, was developed.

Streptococcus pyogenes Surveillance Through Surface Swab Samples to Track the Emergence of Streptococcal Toxic Shock Syndrome in Rural JapanJapan recently experienced a record surge in streptococcal toxic shock syndrome. Our environmental surveillance study reveals that Streptococcus pyogenes persists seasonally, peaking in autumn and winter in rural Japan. The dominant emm1 M1UK sublineage and csrS mutations heighten virulence, highlighting the urgent need for targeted surveillance and interventions.

Complete genome sequence of Burkholderia cenocepacia bacteriophage Karil-mokiny-1Burkholderia cepacia complex causes life-threatening respiratory infections. Here, a bacteriophage with activity against B. cenocepacia was isolated from wastewater. It has a genome size of 70,144 bp and has the taxonomic classification Irusalimvirus. It has no genes associated with lysogeny, bacterial resistance, or virulence.

Thoracic Society of Australia and New Zealand position statement: The safe clinical use of sputum induction for bio-sampling of the lower airways in children and adultsSputum induction is widely used in clinical settings for collection of biological samples from the lower airways. However, in recent years sputum induction has been associated with serious adverse events and even death. This position statement was commissioned by the Thoracic Society of Australia and New Zealand to address major adverse events of two deaths associated with sputum induction that have occurred in Australia in 2021, and outlines best practice for the safe use of sputum induction.

Airway macrophages display decreased expression of receptors mediating and regulating scavenging in early cystic fibrosis lung diseaseCystic fibrosis (CF) airway disease is characterized by chronic inflammation, featuring neutrophil influx to the lumen. Airway macrophages (AMs) can promote both inflammation and resolution, and are thus critical to maintaining and restoring homeostasis. CF AM functions, specifically scavenging activity and resolution of inflammation, have been shown to be impaired, yet underlying processes remain unknown.

Investigating the Implications of CFTR Exon Skipping Using a Cftr Exon 9 Deleted Mouse ModelSeverity and disease progression in people with Cystic Fibrosis is typically dependent on their genotype. One potential therapeutic strategy for people with specific mutations is exon skipping with antisense oligonucleotides. CFTR exon 9 is an in-frame exon and hence the exclusion of this exon would excise only 31 amino acids but not alter the reading frame of the remaining mRNA.

Development and validation of a miniaturized bacteriophage host range screening assay against antibiotic resistant Pseudomonas aeruginosaAntimicrobial resistance is a current global health crisis, and the increasing emergence of multidrug resistant infections has led to the resurgent interest in bacteriophages as an alternative treatment.

The respiratory health effects of acute in vivo diesel and biodiesel exhaust in a mouse modelBiodiesel, a renewable diesel fuel that can be created from almost any natural fat or oil, is promoted as a greener and healthier alternative to commercial mineral diesel without the supporting experimental data to back these claims. The aim of this research was to assess the health effects of acute exposure to two types of biodiesel exhaust, or mineral diesel exhaust or air as a control in mice.

Genome Sequence of a Lytic Staphylococcus aureus Bacteriophage Isolated from Breast MilkWe identified a double-stranded DNA (dsDNA) bacteriophage appearing to belong to Herelleviridae, genus Kayvirus. The bacteriophage, Biyabeda-mokiny 1, was isolated from breast milk using a clinical isolate of Staphylococcus aureus.
