Pulmonary bacteriophage and cystic fibrosis airway mucus: friends or foes?For those born with cystic fibrosis (CF), hyper-concentrated mucus with a dysfunctional structure significantly impacts CF airways, providing a perfect environment for bacterial colonization and subsequent chronic infection. Early treatment with antibiotics limits the prevalence of bacterial pathogens but permanently alters the CF airway microenvironment, resulting in antibiotic resistance and other long-term consequences.

Multi-ancestry genome-wide association analyses improve resolution of genes and pathways influencing lung function and chronic obstructive pulmonary disease riskLung-function impairment underlies chronic obstructive pulmonary disease (COPD) and predicts mortality. In the largest multi-ancestry genome-wide association meta-analysis of lung function to date, comprising 580,869 participants, we identified 1,020 independent association signals implicating 559 genes supported by ≥2 criteria from a systematic variant-to-gene mapping framework. These genes were enriched in 29 pathways. Individual variants showed heterogeneity across ancestries, age and smoking groups, and collectively as a genetic risk score showed strong association with COPD across ancestry groups.

Gene filtering strategies for machine learning guided biomarker discovery using neonatal sepsis RNA-seq dataMachine learning (ML) algorithms are powerful tools that are increasingly being used for sepsis biomarker discovery in RNA-Seq data. RNA-Seq datasets contain multiple sources and types of noise (operator, technical and non-systematic) that may bias ML classification. Normalisation and independent gene filtering approaches described in RNA-Seq workflows account for some of this variability and are typically only targeted at differential expression analysis rather than ML applications.

Western Australia remote aeromedical substance use disorders outcomesSubstance use disorders (SUDs) cause significant harm to regional Australians, who are more likely to misuse alcohol and other drugs (AODs) and encounter difficulty in accessing treatment services. The primary aims of this study were to describe the demographics of patients aeromedically retrieved from regional locations and compare hospital outcomes with a metropolitan-based cohort.

Phase 3 Trial of Epicutaneous Immunotherapy in Toddlers with Peanut AllergyNo approved treatment for peanut allergy exists for children younger than 4 years of age, and the efficacy and safety of epicutaneous immunotherapy with a peanut patch in toddlers with peanut allergy are unknown.

Invasive Infections Caused by Lancefield Groups C/G and A Streptococcus, Western Australia, Australia, 2000–2018Epidemiologic data on invasive group C/G Streptococcus (iGCGS) infections are sparse internationally. Linked population-level hospital, pathology, and death data were used to describe the disease burden in Western Australia, Australia, during 2000-2018 compared with that of invasive group A Streptococcus (GAS, Streptococcus pyogenes) infections.

Awake and Alert: Examining the Portrayal of Energy Drinks on TikTokEnergy drinks (EDs) are not recommended for minors' consumption due to a myriad of health risks, but marketing initiatives persist. This study explored the promotion of EDs on TikTok, a platform frequented by children and adolescents.

Anoctamins and Calcium Signalling: An Obstacle to EGFR Targeted Therapy in Glioblastoma?Glioblastoma is the most common form of high-grade glioma in adults and has a poor survival rate with very limited treatment options. There have been no significant advancements in glioblastoma treatment in over 30 years. Epidermal growth factor receptor is upregulated in most glioblastoma tumours and, therefore, has been a drug target in recent targeted therapy clinical trials.

COVID-19 vaccine knowledge, attitudes, and experiences of health care workers in Perth, Western Australia: A qualitative studyHealth care workers (HCWs) faced an increased risk of Coronavirus Disease 2019 (COVID-19). Australia’s COVID-19 vaccine rollout commenced in February 2021 to priority groups, including HCWs. Given their increased risk, as well as influence on patients’ vaccine uptake, it was important that HCWs had a positive COVID-19 vaccination experience, as well as trusting the vaccine safety and efficacy data.

Discovery of 42 genome-wide significant loci associated with dyslexiaReading and writing are crucial life skills but roughly one in ten children are affected by dyslexia, which can persist into adulthood. Family studies of dyslexia suggest heritability up to 70%, yet few convincing genetic markers have been found.
