Avian influenza viruses (AIVs) pose a growing global health threat, particularly in low- and middle-income countries (LMICs), where limited surveillance capacity and under-resourced healthcare systems hinder timely detection and response. Migratory birds play a significant role in the transboundary spread of AIVs, yet data from key regions along migratory flyways remain sparse. To address these surveillance gaps, we conducted a study between December 2021 and February 2023 using fresh bird guano collected across 10 countries in the Global South.
Pseudomonas aeruginosa infections in the lungs affect millions of children and adults worldwide. To our knowledge, no clinically validated prognostic biomarkers for chronic pulmonary P. aeruginosa infections exist. Therefore, this study aims to identify potential prognostic markers for chronic P. aeruginosa biofilm lung infections.
Autistic adolescents are vulnerable to sleep difficulties, with up to 80 % experiencing sleep problems, most commonly insomnia. Little is known about how autistic adolescents are involved in their own sleep treatment, and their depth of knowledge about their sleep difficulties. The aims of this study were to investigate autistic adolescent and parent perspectives of experiencing and managing insomnia, and what factors influence the development of these perspectives on insomnia and treatment.
Cytokines of the TGF-β superfamily control essential cell fate decisions via receptor regulated SMAD (R-SMAD) transcription factors. Ligand-induced R-SMAD phosphorylation in the cytosol triggers their activation and nuclear accumulation. We determine how R-SMADs are inactivated by dephosphorylation in the cell nucleus to counteract signaling by TGF-β superfamily ligands.
Tick bites and tick-related diseases are on the rise. Diagnostic tests that identify well-characterised tick-borne pathogens (TBPs) possess limited capacity to address the causation of symptoms associated with poorly characterised tick-related illnesses, such as debilitating symptom complexes attributed to ticks (DSCATT) in Australia. Identification of local signals in tick-bitten skin that can be detected systemically in blood would have both clinical (diagnostic or prognostic) and research (mechanistic insight) utility, as a blood sample is more readily obtainable than tissue biopsies.
Preterm birth is associated with increased mortality and morbidity, particularly due to lung disease. Low- and middle-income countries (LMIC) have the highest rates of preterm birth. Infants born extremely preterm rarely survive, so the largest burden is amongst moderate-to-late preterm (MLP) infants. The long-term health impact on MLP children in LMIC is poorly understood. The aim of this study was to assess the effect of MLP birth on lung function trajectories from birth to 5 years in the Drakenstein Child Health Study.
Culturally safe healthcare approaches are important to improve outcomes of Indigenous people. Non-Indigenous clinicians are often ill-prepared to provide such healthcare. The NHMRC Centre for Research Excellence (CRE) especially for First Nations Children has been studying for several years how to improve clinical care for Indigenous children with respiratory disease in hospital, clinic, urban, rural and remote settings.
Respiratory oscillometry (or the forced oscillation technique) is a highly practical lung function test that can be applied in a wide range of clinical scenarios in children and adults, including the clinic, intensive care unit, patient home monitoring and emergency departments. Oscillometry measurements complement spirometry in detecting abnormal lung function, measuring effects of treatment such as inhaled corticosteroids or bronchodilators, and changes due to disease activity.
Active nasal surveillance culture (ANSC) is recognized to enable rapid detection of antibiotic-resistant bacteria in the intensive care unit (ICU), which can contribute to the prevention of Ventilator-associated pneumonia (VAP). This study aims to evaluate the usefulness of ANSC in assessing the development of VAP in ICU patients.
The twenty-first century has seen a fundamental shift in disease epidemiology with anthropogenic environmental change emerging as the likely dominant factor affecting the distribution and severity of current and future human disease. This is especially true of allergic diseases and asthma with their intimate relationship with the natural environment.
