Biomarker signatures for progressive idiopathic pulmonary fibrosisIdiopathic Pulmonary Fibrosis (IPF) is a progressive lung disease in which circulatory biomarkers has the potential for guiding management in clinical practice. We assessed the prognostic role of serum biomarkers in three independent IPF cohorts, the Australian IPF Registry (AIPFR), Trent Lung Fibrosis (TLF) and Prospective Observation of Fibrosis in the Lung Clinical Endpoints (PROFILE).

Interparental Conflict Across the Early Parenting Period: Evidence From Fathers Participating in an Australian Population-Based StudyCurrent evidence about the prevalence of interparental conflict (IPC) during early parenthood is primarily based on mothers’ reports. Drawing upon Australian longitudinal data from 4136 fathers, the aims of the study were to report on the extent to which fathers report IPC across six biennial time intervals when their children were aged 6–12 months to 10–11 years, identify trajectories of IPC over time and identify postnatal factors (at the initial time point) associated with high risk trajectories of IPC.

WALLABY Pre-Pilot Survey: The effects of angular momentum and environment on the H i gas and star formation properties of galaxies in the Eridanus supergroupWe use high-resolution ASKAP observations of galaxies in the Eridanus supergroup to study their H i, angular momentum, and star formation properties, as part of the WALLABY pre-pilot survey efforts.

Methods for modelling excess mortality across England during the COVID-19 pandemicExcess mortality is an important measure of the scale of the coronavirus-2019 pandemic. It includes both deaths caused directly by the pandemic, and deaths caused by the unintended consequences of containment such as delays to accessing care or postponements of healthcare provision in the population.

Neonatal sepsis definitions from randomised clinical trialsNeonatal sepsis is a leading cause of infant mortality worldwide with non-specific and varied presentation. We aimed to catalogue the current definitions of neonatal sepsis in published randomised controlled trials.

Small-molecule screen reveals synergy of cell cycle checkpoint kinase inhibitors with DNA-damaging chemotherapies in medulloblastomaMedulloblastoma (MB) consists of four core molecular subgroups with distinct clinical features and prognoses. Treatment consists of surgery, followed by radiotherapy and cytotoxic chemotherapy. Despite this intensive approach, outcome remains dismal for patients with certain subtypes of MB, namely, MYC-amplified Group 3 and TP53-mutated SHH. Using high-throughput assays, six human MB cell lines were screened against a library of 3208 unique compounds. We identified 45 effective compounds from the screen and found that cell cycle checkpoint kinase (CHK1/2) inhibition synergistically enhanced the cytotoxic activity of clinically used chemotherapeutics cyclophosphamide, cisplatin, and gemcitabine.

A study protocol for a randomised controlled trial to evaluate the effectiveness of a dog-facilitated physical activity minimal intervention on young children's physical activity, health and development: the PLAYCE PAWS trialPet ownership brings many health benefits to individuals. In children developmental benefits can extend to improved self-esteem, better social competence and decreased loneliness. The majority of households with children own a dog, however only a small proportion of children gain the benefits of dog ownership through dog walking and play. There are few intervention studies investigating the impact of dog-facilitated physical activity in children. The PLAYCE PAWS study aims to test a minimal-contact intervention through the use of mobile health ("mhealth") strategies, i.e. text (SMS) messages, to parents to encourage their children to walk and play with their dog more, and evaluate the impact on children's overall physical activity and development.

Exploring genotype-phenotype relationships in the CDKL5 deficiency disorder using an international datasetCharacterized by early-onset seizures, global developmental delay and severe motor deficits, CDKL5 deficiency disorder is caused by pathogenic variants in the cyclin-dependent kinase-like 5 gene. Previous efforts to investigate genotype-phenotype relationships have been limited due to small numbers of recurrent mutations and small cohort sizes. Using data from the International CDKL5 Disorder Database we examined genotype-phenotype relationships for 13 recurrent CDKL5 variants and the previously analyzed historic variant groupings. We have applied the CDKL5 Developmental Score (CDS) and an adapted version of the CDKL5 Clinical Severity Assessment (CCSA), to grade the severity of phenotype and developmental outcomes for 285 individuals with CDKL5 variants.

Investigating Mitochondrial Transcriptomes and RNA Processing Using Circular RNA SequencingTranscriptomic technologies have revolutionized the study of gene expression and RNA biology. Different RNA sequencing methods enable the analyses of diverse species of transcripts, including their abundance, processing, stability, and other specific features. Mitochondrial transcriptomics has benefited from these technologies that have revealed the surprising complexity of its RNAs. Here we describe a method based upon cyclization of mitochondrial RNAs and next generation sequencing to analyze the steady-state levels and sizes of mitochondrial RNAs, their degradation products, as well as their processing intermediates by capturing both 5' and 3' ends of transcripts.

The association between migrant status and transition in an ultra-high risk for psychosis populationMigrant status is one of the most replicated and robust risk factors for developing a psychotic disorder. This study aimed to determine whether migrant status in people identified as Ultra-High Risk for Psychosis (UHR) was associated with risk of transitioning to a full-threshold psychotic disorder. Hazard ratios for the risk of transition were calculated from five large UHR cohorts (n = 2166) and were used to conduct a meta-analysis using the generic inverse-variance method using a random-effects model.
