What are the novel findings of this work? Preterm delivery occurred in a higher proportion of women with SARS-CoV-2 infection in the PAN-COVID and AAP-SONPM registries compared to contemporaneous and historical national data from uninfected women in the UK and USA. The majority of preterm deliveries occurred between 32 + 0 and 36 + 6 weeks' gestation. SARS-CoV-2 infection in pregnancy did not appear to be associated with a clinically significant effect on fetal growth, adverse neonatal outcome or the rate of stillbirth. Although maternal death was uncommon, the rate was higher than expected based on UK and USA population data, which is likely explained by underascertainment of women affected by milder or asymptomatic infection in pregnancy in the PAN-COVID study, although not in the AAP-SONPM study. What are the clinical implications of this work? Pregnant women should be counseled that SARS-CoV-2 infection increases the risk of preterm delivery but not stillbirth, early neonatal death or a small baby. Healthcare providers should recommend SARS-CoV-2 vaccination in pregnant women and women planning pregnancy, alongside enhanced social distancing.
Manufacturing has been the key factor limiting rollout of vaccination during the COVID-19 pandemic, requiring rapid development and large-scale implementation of novel manufacturing technologies. ChAdOx1 nCoV-19 (AZD1222, Vaxzevria) is an efficacious vaccine against SARS-CoV-2, based upon an adenovirus vector. We describe the development of a process for the production of this vaccine and others based upon the same platform, including novel features to facilitate very large-scale production. We discuss the process economics and the "distributed manufacturing"
RHD remains a significant cause of premature mortality for Aboriginal people in the Kimberley, with mortality rates unmatched in the general Australian population since the first half of the 20th century. Efforts to reduce progression of this disease through RHD Register and Control Programs are crucial alongside action to address underlying socioeconomic and environmental inequities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
