COVID-19 is a new multi-organ disease causing considerable worldwide morbidity and mortality. While many recognized pathophysiological mechanisms are involved, their exact causal relationships remain opaque. Better understanding is needed for predicting their progression, targeting therapeutic approaches, and improving patient outcomes. While many mathematical causal models describe COVID-19 epidemiology, none have described its pathophysiology.
Respiratory syncytial virus (RSV) seasonality is dependent on the local climate. We assessed the stability of RSV seasonality prior to the SARS-CoV-2 pandemic in Western Australia (WA), a state spanning temperate and tropical regions.
Invasive pulmonary aspergillosis remains a major cause of morbidity and mortality for immunocompromised children, particularly for patients with acute leukaemia and those undergoing haematopoietic stem cell transplantation. Timely diagnosis, using a combination of computed tomography (CT) imaging and microbiological testing, is key to improve prognosis, yet there are inherent challenges in this process. For CT imaging, changes in children are generally less specific than those reported in adults and recent data are limited.
Pneumonia remains a leading cause of hospitalization and death among young children worldwide, and the diagnostic challenge of differentiating bacterial from non-bacterial pneumonia is the main driver of antibiotic use for treating pneumonia in children. Causal Bayesian networks (BNs) serve as powerful tools for this problem as they provide clear maps of probabilistic relationships between variables and produce results in an explainable way by incorporating both domain expert knowledge and numerical data.
The need for coronavirus 2019 (COVID-19) vaccination in different age groups and populations is a subject of great uncertainty and an ongoing global debate. Critical knowledge gaps regarding COVID-19 vaccination include the duration of protection offered by different priming and booster vaccination regimens in different populations, including homologous or heterologous schedules.
Respiratory syncytial virus (RSV) is a significant cause of respiratory infections in young children. Since 2021, RSV has been a notifiable disease in Australia. However, current surveillance systems focus on hospitalised RSV, with limited surveillance at a community level through primary care clinics. This approach only captures RSV requiring hospitalisation. Less severe illnesses, while not captured, may have significant social and economic impacts including the associated cost of care and absenteeism. The aim of this study is to establish an understanding of the broader burden of RSV in young children in a community setting.
The Healthy Living Practices (HLPs) outline nine essential guidelines for maintaining health in remote Aboriginal communities, yet high costs and poor availability make them financially out of reach for many families. We assessed the cost and availability of essential goods required to support the HLPs in eight remote Kimberley community stores, recording prices during three visits in 2022 as part of the SToP (See, Treat, Prevent) Skin Sores and Scabies Trial, and retrospectively comparing these (inflation-adjusted) with Perth and Broome prices in 2024.
Vancomycin is used to treat serious gram-positive infections in children; however, effective dosing information for those aged 3 months to 18 years is limited. We aimed to determine an optimized dosing strategy for this age group.
Vancomycin is first-line treatment for methicillin-resistant Staphylococcus aureus infections. However, despite guideline recommendations, there is no evidence that targeting vancomycin trough concentrations of ≥15 mg/L in children confers clinical benefit and is associated with vancomycin-associated nephrotoxicity.
To determine the incidence, serotype distribution and clinical outcomes of invasive pneumococcal disease in children with acute lymphoblastic leukaemia following widespread use of pneumococcal conjugate vaccines.
