Childhood leukaemia in Down's syndrome primed by blood-cell biasAn in-depth investigation of gene regulation and cell populations at sites of fetal blood-cell production provides clues as to why children with Down’s syndrome are predisposed to developing leukaemia.

Development and temporal validation of a clinical prediction model of transition to psychosis in individuals at ultra-high risk in the UHR 1000+ cohortThe concept of ultra-high risk for psychosis (UHR) has been at the forefront of psychiatric research for several decades, with the ultimate goal of preventing the onset of psychotic disorder in high-risk individuals. Orygen (Melbourne, Australia) has led a range of observational and intervention studies in this clinical population.

Mapping the global prevalence, incidence, and mortality of Plasmodium falciparum and Plasmodium vivax malaria, 2000-22: a spatial and temporal modelling studyMalaria remains a leading cause of illness and death globally, with countries in sub-Saharan Africa bearing a disproportionate burden. Global high-resolution maps of malaria prevalence, incidence, and mortality are crucial for tracking spatially heterogeneous progress against the disease and to inform strategic malaria control efforts. We present the latest such maps, the first since 2019, which cover the years 2000–22. The maps are accompanied by administrative-level summaries and include estimated COVID-19 pandemic-related impacts on malaria burden.

Association of preoperative nocturnal hypoxaemia nadir and fentanyl ventilatory sensitivity in children with obstructive sleep apnoea undergoing general anaesthesiaObstructive sleep apnoea (OSA) has been thought to increase the risk of respiratory depression from opioids. The primary aim of this study was to assess whether preoperative hypoxaemia by sleep study pulse oximetry imparts greater opioid sensitivity.

Quantifying undetected tuberculosis in Ethiopia using a novel geospatial modelling approachTuberculosis (TB) is the leading infectious cause of death globally, with approximately three million cases remaining undetected, thereby contributing to community transmission. Understanding the spatial distribution of undetected TB in high-burden settings is critical for designing and implementing geographically targeted interventions for early detection and control.

Quicker team launch times for urgent priority neonatal retrievals: A Quality Improvement Initiative studyNeonatal retrieval networks have adopted time-centric quality metrics as Key Performance Indicators (KPI) for setting and comparing benchmarking standards. Quicker launch time (departure from base), an essential KPI, enables neonatal retrieval teams to rapidly provide higher-level care to sick infants. The Newborn Emergency Transport Services of Western Australia (NETS WA) facilitates neonatal transfers across largest global retrieval area necessitating quicker team launch times for urgent retrievals. NETS WA conducted a quality improvement (QI) study to quicken team launch times for urgent retrievals.

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.

Concentration of food allergens in breastmilk and association with maternal factors– A systematic reviewCommon food allergens have been detected in breast milk with wide inter-individual variations in concentrations. As maternal factors, such as age, smoking, and body mass index have been associated with breast milk composition, we aimed to identify maternal characteristics associated with the concentration of food allergens in breast milk.

Benchmarking Imputed Low Coverage Genomes in a Human Population Genetics ContextOngoing advances in population genomic methodologies have recently enabled the study of millions of loci across hundreds of genomes at a relatively low cost, by leveraging a combination of low-coverage shotgun sequencing and innovative genotype imputation methods. This approach has the potential to provide abundant genotype information at low costs comparable to another widely used cost-effective genotyping approach-that is, SNP panels-while avoiding potential issues related to loci being ascertained in distantly related populations.

A modular approach to forecasting COVID-19 hospital bed occupancyMonitoring the number of COVID-19 patients in hospital beds was a critical component of Australia's real-time surveillance strategy for the disease. From 2021 to 2023, we produced short-term forecasts of bed occupancy to support public health decision-making.
