Introduction: The incidence of gestational diabetes mellitus (GDM) in Australia has tripled in the last 20 years. Consequently, over 40ā€‰000 pregnancies are now diagnosed as 'higher risk' each year. This has increased antenatal surveillance and obstetric intervention, often in the form of delivery earlier than 39 weeks gestation.

The goal of this study was to compare the bioaccumulation of the PCB mixture Aroclor 1254 in zebrafish to cardiac and neurologic outcomes. The establishment of effect concentrations (ECs) for cardiac and neurotoxic effects of PCBs in early life stage fish is challenging due to a lack of measured PCB concentrations in test media (e.g.

Background: The impact of pre-infection vaccination on the risk of long COVID remains unclear in the pediatric population. We aim to assess the effectiveness of BNT162b2 on long COVID risks with various strains of the SARS-CoV-2 virus in children and adolescents, using comparative effectiveness methods. We further explore if such pre-infection vaccination can mitigate the risk of long COVID beyond its established protective benefits against SARS-CoV-2 infection using causal mediation analysis.

As a result of human activity, Earth's atmosphere and climate are changing at an unprecedented pace. Models based on short-term experiments predict major changes will occur in marine phytoplankton communities in the future ocean, but rarely consider how evolution or interactions with other microbes may influence these changes. Here we experimentally evolved several phytoplankton in co-culture with a heterotrophic bacterium, Alteromonas sp.

Background And Aims: Public perceptions of alcohol and its related harms and policies are shaped by multiple discourses and can influence behaviour and policy support. As part of a FrameWorks-informed project to test framing approaches to improve public understanding and support for evidence-based alcohol policies in the UK, this research aimed to (i) summarise relevant evidence; (ii) compare how public understanding of alcohol harms differs from those of academic and charity experts; and (iii) develop novel framing approaches.

Methods: (1) a literature review including systematic, scoping and targeted components to understand previous evidence on effective framing from behaviour change, UK alcohol policy and FrameWorks literatures; (2) comparison of public views of alcohol harms and policies from four focus groups (nā€‰=ā€‰20) with those of public health experts; (3) an iterative process involving workshops and stakeholder consultation to develop 12 novel framing approaches.
