The reported frequency and types of adverse events following initial vaccination and revaccination with Bacille Calmette-Guérin (BCG) varies worldwide. Using active surveillance in a randomised controlled trial of BCG vaccination (the BRACE trial), we determined the incidence and risk factors for the development of BCG injection site abscess and regional lymphadenopathy.

Research

Ion channel activity underlying biological processes that drive high-grade gliomas (HGG) is largely unknown. We aimed to determine the networking of ion channel genes and validate their expression within HGG patient tumors, to identify ion channel-targeting drugs that would inhibit tumor-promoting processes.

Research

The coronavirus (COVID-19) pandemic has seen a global surge in anxiety, depression, post-traumatic stress disorder (PTSD), and stress. Aims: This study aimed to describe the perspectives of patients with COVID-19, their family, health professionals, and the general public on the impact of COVID-19 on mental health.

Research

Dissociation is often distressing, yet how affected adolescents manage dissociation in their daily lives is not well understood. This study aimed to describe the strategies adolescents use to manage dissociative symptoms from the perspective of adolescents themselves, their parents, and their clinicians.

Research

Due to global climate change–induced shifts in species distributions, estimating changes in community composition through the use of Species Distribution Models has become a key management tool. Being able to determine how species associations change along environmental gradients is likely to be pivotal in exploring the magnitude of future changes in species’ distributions.

Research

Septo-optic dysplasia (SOD) is a congenital disorder affecting 1 in 10,000 births, defined by the presence of at least two of a clinical triad, consisting of optic nerve hypoplasia, midline brain defects and pituitary hormone deficiency. Children with SOD may have vision impairment, hormonal deficiencies, developmental disorders, or epilepsy, but the clinical picture is highly variable. The complexity of SOD, its interplay with family factors, and the need for multiple specialty commitments can make the diagnosis period a challenging time for families.

Research

Child temperament and caregiver psychological distress have been independently associated with social-emotional difficulties among individuals with autism. However, the interrelationship among these risk factors has rarely been investigated.

Research

Small airway and lung parenchymal abnormalities frequently occur following preterm birth but are commonly missed by spirometry. Static lung volumes, diffusing capacity of the lung for carbon monoxide (D LCO) and oscillometry provide a more precise characterisation of these conditions. We hypothesised that differences in these measures exist between individuals born preterm and at term and we aimed to systematically review the literature to identify and quantify these differences in lung function.

Research

War and conflict severely disrupt public health systems, compromising infectious disease surveillance in many affected regions. Mpox, a re-emerging zoonotic disease, poses a growing global threat, especially in areas where traditional monitoring is inaccessible.The mpox virus has distinct clades with varying transmission and severity.

Research

There is no clear clinical guidance on the use of alcohol pharmacotherapies in pregnancy due to insufficient safety information. Contraception should therefore be considered for reproductive-aged females receiving alcohol pharmacotherapies not wishing to become pregnant. This study evaluated the concurrent use of alcohol pharmacotherapies with prescription contraception and other medications in Australian females of reproductive age compared to those not receiving an alcohol pharmacotherapy.

Research

Beaches are important settings for physical activity, with their quality (safety, amenities, aesthetics) influencing how well they support health. The quality of beaches may differ across neighbourhoods, with higher socioeconomic status neighbourhoods having disproportionately better access to beaches. This study examined the attributes of and activities taking place in beaches by neighbourhood socioeconomic status.

Research

Children in out-of-home care participate in less organised sport than children from other household structures, potentially reducing opportunities for improvements in social, developmental, and health outcomes. Despite this, little is known about barriers and facilitators of sport participation for children in care. We aimed to explore carers' perspectives on the influences on children in care's participation and experiences in organised sport.

Research

In 2022, the World Health Organization extended their guidelines for perennial malaria chemoprevention (PMC) from infants to children up to 24 months old. However, evidence for PMC's public health impact is primarily limited to children under 15 months. Further research is needed to assess the public health impact and cost-effectiveness of PMC, and the added benefit of further age-expansion. We integrated an individual-based model of malaria with pharmacological models of drug action to address these questions for PMC and a proposed age-expanded schedule (referred as PMC+, for children 03-36 months).

Research

Between January 2022 and December 2023, there were 1,827 bloodstream infection (BSI) isolates in 1,745 children and adolescents reported to the Australian Group on Antimicrobial Resistance (AGAR) surveillance outcome programs, with 40% of episodes in children aged < 12 months.
