Vitamin D and SunlightIn a sunny country such as Australia, it’s important to identify how to achieve the right amount of sun exposure for good health. We need to be able to harness the benefits of vitamin D and sunlight while remaining protected from the proven dangers of too much UV radiation.

Clostridioides (Clostridium) difficile in children and adolescents in the community in CambodiaClostridioides (Clostridium) difficile transmission between community and healthcare settings has been increasingly reported. We aimed to identify the prevalence and molecular epidemiology of C. difficile colonising adolescents and non-hospitalised children in Cambodia.

Longitudinal Profiling of the Human Milk Microbiome from Birth to 12 Months Reveals Overall Stability and Selective Taxa-Level VariationHuman milk bacteria contribute to gut microbiome establishment in breastfed infants. Although breastfeeding is recommended throughout infancy, temporal variation in the milk microbiome-particularly beyond solid food introduction-remains understudied. We analyzed 539 milk samples from 83 mother-infant dyads between 1 week and 12 months postpartum using full-length 16S rRNA gene sequencing.

Cardiac monitoring safety assessment framework for early phase group a streptococcal vaccine trialsThis paper presents a comprehensive cardiac safety framework for early clinical development of Streptococcus pyogenes (Group A Streptococcus) vaccines, endorsed by the Strep A Vaccine Global Consortium and the Australian Strep A Vaccine Initiative. Given historical concerns about vaccine-associated acute rheumatic fever, we have established standardized echocardiography protocols integrated with clinical assessment for monitoring cardiac safety in early-phase vaccine trials.

Acellular Pertussis Vaccine Given in the Week After Birth Does Not Impair Antibody Responses to Later Childhood DosesA birth acellular pertussis vaccine may be a valuable alternative for immunity against infant pertussis when a pregnancy pertussis vaccine has not been administered. We assessed whether a birth dose may impair immunoglobulin G (IgG) responses to childhood pertussis boosters.

Suppression of TGF-β/SMAD signaling by an inner nuclear membrane phosphatase complexCytokines 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.

The overlapping global distribution of dengue, chikungunya, Zika and yellow feverArboviruses transmitted mainly by Aedes (Stegomyia) aegypti and Ae. albopictus, including dengue, chikungunya, and Zika viruses, and yellow fever virus in urban settings, pose an escalating global threat. Existing risk maps, often hampered by surveillance biases, may underestimate or misrepresent the true distribution of these diseases and do not incorporate epidemiological similarities despite shared vector species.

What influences the implementation of health checks in the prevention and early detection of chronic diseases among Aboriginal and Torres Strait Islander people in Australian health careThis review aims to systematically identify contextual and mechanistic factors that contribute to the success or failure of implementing effective HCs in the prevention and early detection of chronic diseases among Aboriginal and Torres Strait Islander people in Australian primary health care (PHC).

What helps cardiac patients exercise after treatment, and when? Understanding physical activity and exercise participation following exercise-based cardiac rehabilitationDespite evidence suggesting regular exercise (i.e. structured, repetitive and purposeful physical activity) attenuates cardiac patients’ decline in health, our understanding of factors affecting long-term exercise participation among this patient cohort is limited. This problem is pertinent, given that less than half of cardiac patients adhere to exercise following discharge from formal exercise-based rehabilitation programmes. In this study, we explored factors influencing exercise participation after an outpatient cardiac rehabilitation programme.

E-cigarette use among gender and sexuality diverse (LGBTQA+) adolescents in Australia: The case for LGBTQA+ affirmative harm reductionThis study aimed to provide a first-ever comprehensive epidemiology of vaping behaviours among Australian gender and sexuality diverse (LGBTQA+) youth.
