Options and realities for trans and gender diverse young people receiving care in Australia's mental health system: findings from Trans Pathways

Trans and gender diverse young people experience mental health difficulties self-harm and suicidality at markedly higher rates than the general population, yet they often feel isolated from mental health services. There is little qualitative research on the experiences of trans and gender diverse young people accessing mental health support in Australia.

Validation of a rapid, saliva-based, and ultra-sensitive SARS-CoV-2 screening system for pandemic-scale infection surveillance

Without any realistic prospect of comprehensive global vaccine coverage and lasting immunity, control of pandemics such as COVID-19 will require implementation of large-scale, rapid identification and isolation of infectious individuals to limit further transmission. Here, we describe an automated, high-throughput integrated screening platform, incorporating saliva-based loop-mediated isothermal amplification (LAMP) technology, that is designed for population-scale sensitive detection of infectious carriers of SARS-CoV-2 RNA.

The bone marrow microenvironment of pre-B acute lymphoblastic leukemia at single-cell resolution

The bone marrow microenvironment (BMM) plays a key role in leukemia progression, but its molecular complexity in pre-B cell acute lymphoblastic leukemia (B-ALL), the most common cancer in children, remains poorly understood. To gain further insight, we used single-cell RNA sequencing to characterize the kinetics of the murine BMM during B-ALL progression.

Complications associated with paediatric airway management during the COVID-19 pandemic: an international, multicentre, observational study

Respiratory adverse events in adults with COVID-19 undergoing general anaesthesia can be life-threatening. However, there remains a knowledge gap about respiratory adverse events in children with COVID-19. We created an international observational registry to collect airway management outcomes in children with COVID-19 who were having a general anaesthetic.

Socioethnic disparities in severe maternal morbidity in Western Australia: a statewide retrospective cohort study

To assess the scale of ethnic inequalities in severe maternal morbidity (SMM) rates and quantify the contribution of maternal characteristics to these disparities. This is a retrospective cohort study. A whole-of-population linked administrative data from 2002 to 2015 in Western Australia.

Research

Transfers of disadvantage across three generations using latent class associations within families

There is a large volume of research on the persistence of advantage and disadvantage across generations. Intergenerational studies typically address family resources as independent factors, which ignores how risks cluster together and accumulate over time.

Research

Beta-lactam-induced immediate hypersensitivity reactions: A genome-wide association study of a deeply phenotyped cohort

Background: β-lactam antibiotics are associated with a variety of immune-mediated or hypersensitivity reactions, including immediate (type I) reactions mediated by antigen-specific IgE. Objective: We sought to identify genetic predisposing factors for immediate reactions to β-lactam antibiotics.

SLC6A14 Impacts Cystic Fibrosis Lung Disease Severity via mTOR and Epithelial Repair Modulation

Cystic fibrosis (CF), due to pathogenic variants in CFTR gene, is associated with chronic infection/inflammation responsible for airway epithelium alteration and lung function decline. Modifier genes induce phenotype variability between people with CF (pwCF) carrying the same CFTR variants. Among these, the gene encoding for the amino acid transporter SLC6A14 has been associated with lung disease severity and age of primary airway infection by the bacteria Pseudomonas aeruginosa.

Research

Narrowband UVB phototherapy reduces TNF production by B-cell subsets stimulated via TLR7 from individuals with early multiple sclerosis

At the end of a 60-day course of narrowband UVB phototherapy, administered to individuals with early multiple sclerosis, there were changes in the relative proportions of circulating B-cell subsets. This study investigated phototherapy-associated changes to cytokine responses of B cells when exposed to a TLR7 ligand.

Quality of life in paediatric burn patients with non-severe burns

Burns are common worldwide, and the vast majority are non-severe burns of less than 20% of the total body surface area (TBSA). In Australia, paediatric burns account for a third of all burn admissions, thus understanding the quality-of-life outcomes after a non-severe burn in children is important.

Research

A collaborative approach towards prevention of otitis media in Aboriginal children

Otitis media is very common in Aboriginal children in Western Australia and chronic ear disease causes major problems in speech and language development and education. Up until recently, most programmes dealing with the problem of OM have focused on clinical interventions rather than prevention. The Enhanced Prevention Working Group was established as part of the WA Child Ear Health Strategy (2017–2021). The Group has worked collaboratively to develop a set of recommendations for prevention of OM in Aboriginal children.

Research

Anti-Müllerian hormone concentration is associated with central adiposity and reproductive hormones in expectant fathers

The role of the anti-Müllerian hormone (AMH) as an indicator of physical and reproductive health in men is unclear. We assessed the relationships between AMH and follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and metabolic parameters, in a cohort of expectant fathers.

Planning and clinical role of acute medical home care services for COVID-19: consensus position statement by the Hospital-in-the-Home Society Australasia

During a pandemic when hospitals are stretched and patients need isolation, the role of hospital-in-the-home (HITH) providing acute medical care at home has never been more relevant. We aimed to define and address the challenges to acute home care services posed by the COVID-19 pandemic.

Botrytis cinerea Loss and Restoration of Virulence during In Vitro Culture Follows Flux in Global DNA Methylation

Pathogenic fungi can lose virulence after protracted periods of culture, but little is known of the underlying mechanisms. Here, we present the first analysis of DNA methylation flux at a single-base resolution for the plant pathogen B. cinerea and identify differentially methylated genes/genomic regions associated with virulence erosion during in vitro culture.

Effectiveness of 13-valent pneumococcal conjugate vaccine against hypoxic pneumonia and hospitalisation in Eastern Highlands Province, Papua New Guinea: An observational cohort study

Pneumonia is a leading cause of childhood mortality with Streptococcus pneumoniae a major contributor. Pneumococcal conjugate vaccines (PCVs) have been introduced into immunisation programs in many low- to middle-income countries yet there is a paucity of data evaluating the effectiveness in these settings. We assess the effectiveness of 13-valent PCV against hypoxic pneumonia, hospitalisation and other clinical endpoints in children <5 years living in Eastern Highlands Province, Papua New Guinea).
