Accumulating evidence indicates that antibiotic exposure may lead to impaired vaccine responses, however the mechanisms underlying this association remain poorly understood. Here we prospectively followed 191 healthy, vaginally born, term infants from birth to 15 months, using a systems vaccinology approach to assess the effects of antibiotic exposure on immune responses to vaccination.
This study investigated whether exposure to high pregestational BMI (≥ 25 kg/m2) is associated with alterations in white matter microstructure in early childhood, explored sex-specific effects, and examined associations with cognitive performance.
Limited available data indicate that dementia prevalence rates among Aboriginal and Torres Strait Islander (hereafter Aboriginal) peoples are 3–5 times higher than the overall Australian population. Effective, pragmatic and scalable interventions are urgently required to address this disproportionate burden of dementia in Aboriginal populations.
International guidelines recommend multidisciplinary intervention programs for addressing childhood obesity. In Western Australia, community-based healthy lifestyle programs for children and young people are insufficient for demand, especially for those over-represented in obesity statistics relating to prevalence. This protocol outlines the implementation and evaluation of an adapted, evidenced, community-based program in Perth, Western Australia.
Sex hormones, such as oestrogen and testosterone, display significant immune modulatory properties. This is highly relevant for transgender (trans) people who undergo gender-affirming hormone (GAH) treatment. However, only a limited number of studies have evaluated the immunological impact of GAH treatments, and almost none have assessed the impact in trans young people.
This 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.
Human cutaneous leishmaniasis, a neglected tropical disease caused by Leishmania braziliensis, presents treatment challenges due to varying therapeutic responses. Current therapies often encounter limited efficacy and treatment failure, demanding a deeper understanding of immunopathogenesis and predictive markers.
Tools that can be used to collect behavioural data during pandemics are needed to inform policy and practice. The objective of this project was to develop the Your COVID-19 Risk tool in response to the global spread of COVID-19, aiming to promote health behaviour change. We developed an online resource based on key behavioural evidence-based risk factors related to contracting and spreading COVID-19. This tool allows for assessing risk and provides instant support to protect individuals from infection.
The interaction of genetic and environmental contributions to immunological traits and their association with atopic disease remain unclear. Flow cytometry and in vitro cytokine responses were used to characterize immune profiles from 93 school-aged twin pairs. Using an established twin pair analytical strategy, the genetic and environmental influences on immunological traits were evaluated, along with their association with atopy. Our findings suggest strong genetic influence on several traits, particularly B cell abundance. In contrast, cytokine responses from in vitro stimulations appeared mainly shaped by environmental exposures.
During exacerbations, when symptom and treatment burden are increased, individuals with cystic fibrosis (CF) are likely to prefer airway clearance techniques (ACTs) that require minimal effort. Therefore, in adults with CF who were hospitalised with an exacerbation, we sought to compare the effect of the MetaNeb with usual ACTs on respiratory function and expectorated sputum.
