Maternal diet modulates the infant microbiome and intestinal Flt3L necessary for dendritic cell development and immunity to respiratory infectionPoor maternal diet during pregnancy is a risk factor for severe lower respiratory infections in the offspring, but the underlying mechanisms remain elusive. Here, we demonstrate that in mice a maternal low-fiber diet led to enhanced LRI severity in infants because of delayed plasmacytoid dendritic cell recruitment and perturbation of regulatory T cell expansion in the lungs.

Copy number variation in tRNA isodecoder genes impairs mammalian development and balanced translationThe number of tRNA isodecoders has increased dramatically in mammals, but the specific molecular and physiological reasons for this expansion remain elusive. To address this fundamental question we used CRISPR editing to knockout the seven-membered phenylalanine tRNA gene family in mice, both individually and combinatorially.

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.

Introducing the ORIGINS project: a community-based interventional birth cohortNon-communicable diseases (NCDs) pose the greatest threat to human health globally. The dramatic rise in early onset NCDs - such as childhood obesity, the allergy epidemic and an increasing burden of mental ill health in children and youth - reflect the profound early impact of modern environments on developing systems.

RSV prophylaxis use in high-risk infants in Western Australia, 2002-2013: a record linkage cohort studyThe monoclonal antibody, palivizumab is licensed for use in high-risk infants to prevent severe illness caused by respiratory syncytial virus (RSV). The level of its use and compliance with current jurisdictional guidelines which were amended in 2010, is unknown.

Estimation of the force of infection and infectious period of skin sores in remote Australian communities using interval-censored dataPrevalence of impetigo (skin sores) remains high in remote Australian Aboriginal communities, Fiji, and other areas of socio-economic disadvantage. Skin sore infections, driven primarily in these settings by Group A Streptococcus (GAS) contribute substantially to the disease burden in these areas. Despite this, estimates for the force of infection, infectious period and basic reproductive ratio-all necessary for the construction of dynamic transmission models-have not been obtained.

The plural of anecdote is not data, please mind the gapThe COVID-19 pandemic introduced challenges to everyone in society but particularly so to every aspect of medical practice. It is bewildering how quickly the profession has had to respond to rapidly changing clinical landscape. Our well-established methods involve collecting and analyzing data to generate an evidence base which is then disseminated and implemented into routine clinical practice.

Human erythroleukemia genetics and transcriptomes identify master transcription factors as functional disease driversAcute erythroleukemia (AEL or acute myeloid leukemia [AML]-M6) is a rare but aggressive hematologic malignancy. Previous studies showed that AEL leukemic cells often carry complex karyotypes and mutations in known AML-associated oncogenes.

‘Can you sleep tonight knowing that child is going to be safe?’: Australian community organisation risk work in child protection practiceRisk averse practice has dominated the child protection field for decades, with high-profile child deaths, ever-tightening surveillance, and regulation of families. In this context, the practice of social work as ‘risk work’ including the use of risk assessment tools has been subject to substantial scholarly investigation. Less attention has been paid to the community organisations that play a central role in supporting child protection-involved parents. Based on interviews with Australian community workers, we examine their negotiation of the parent support/parent risk dichotomy.
