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 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.

‘Feeling like you can't do anything because you don't know where to start’—Parents' Perspectives of Barriers and Facilitators to Accessing Early Detection for Children at Risk of CPEarly detection of cerebral palsy (CP) risk is possible from 12 weeks corrected gestational age (CGA) using standardised assessments; however, up to half of children at risk are not referred early, missing out on early intervention. We investigated the barriers and facilitators to accessing early intervention from the perspective of parents of children who did not receive services by 6 months CGA.

A cross-sectional audit of the Australian community food environment highlights the prominent role of chain food outletsFood retail and food service outlets can be part of a chain, or independently operated. Chain food outlets are likely to have the most influence over community food environments but have not been routinely identified in studies which map and monitor access to food, highlighting an important knowledge gap. This study aimed to identify the food retail and food service outlets present within metropolitan Perth, including presence of chain and independent food outlets; and examine differences across local governments.

It’s time for change: inequities and determinants of health-related quality of life among gender and sexually diverse young people in AustraliaThis study was guided by three research aims: firstly, to examine the longitudinal trends of health-related quality of life (HR-QoL) among gender and sexuality diverse (LGBTQA2S+) young people through adolescence (ages 14-19); secondly, to assess longitudinal associations between poor mental health and HR-QoL among LGBTQA2S+ young people through adolescence; and thirdly, to examine differences in HR-QoL among LGBTQA2S+ young people during early adolescence (ages 14 and 15) depending on select school-, peer-, and parent-level factors.

Chronic suppurative otitis mediaChronic suppurative otitis media (CSOM) is a leading global cause of potentially preventable hearing loss in children and adults, associated with socioeconomic deprivation. There is an absence of consensus on the definition of CSOM, which complicates efforts for prevention, treatment, and monitoring.

Shoulder dystocia in babies born to Aboriginal mothers with diabetes: a population-based cohort study, 1998–2015Australian Aboriginal and Torres Strait Islander women with diabetes in pregnancy (DIP) are more likely to have glycaemic levels above the target range, and their babies are thus at higher risk of excessive fetal growth. Shoulder dystocia, defined by failure of spontaneous birth of fetal shoulder after birth of the head requiring obstetric maneuvers, is an obstetric emergency that is strongly associated with DIP and fetal size.

Intervention effect of targeted workplace closures may be approximated by single-layered networks in an individual-based model of COVID-19 controlIndividual-based models of infectious disease dynamics commonly use network structures to represent human interactions. Network structures can vary in complexity, from single-layered with homogeneous mixing to multi-layered with clustering and layer-specific contact weights. Here we assessed policy-relevant consequences of network choice by simulating different network structures within an established individual-based model of SARS-CoV-2 dynamics.
