Analgesics which affect prostaglandin (PG) pathways are used by most pregnant women. As germ cells (GC) undergo developmental and epigenetic changes in fetal life and are PG targets, we investigated if exposure of pregnant rats to analgesics (indomethacin or acetaminophen) affected GC development and reproductive function in resulting offspring (F1) or in the F2 generation. Exposure to either analgesic reduced F1 fetal GC number in both sexes and altered the tempo of fetal GC development sex-dependently, with delayed meiotic entry in oogonia but accelerated GC differentiation in males. These effects persisted in adult F1 females as reduced ovarian and litter size, whereas F1 males recovered normal GC numbers and fertility by adulthood. F2 offspring deriving from an analgesic-exposed F1 parent also exhibited sex-specific changes. F2 males exhibited normal reproductive development whereas F2 females had smaller ovaries and reduced follicle numbers during puberty/adulthood; as similar changes were found for F2 offspring of analgesic-exposed F1 fathers or mothers, we interpret this as potentially indicating an analgesic-induced change to GC in F1. Assuming our results are translatable to humans, they raise concerns that analgesic use in pregnancy could potentially affect fertility of resulting daughters and grand-daughters.
The Coronavirus Disease 2019 (COVID-19) pandemic has resulted in widespread disruption to the healthcare industry. Alongside complex issues relating to ensuring sufficient healthcare capacity and resourcing, healthcare organisations and universities are now also facing heightened cyber-security threats in the midst of the pandemic. Since the outbreak began various healthcare providers and academic institutions across the world have been targeted in a variety of complex and coordinatized cyber-attacks. International and national regulatory bodies have stressed the urgent need for healthcare providers and universities to protect themselves against cyber-attacks during COVID-19, recognising that a growing number of cyber-criminals are seeking to capitalise on the vulnerabilities of the healthcare sector during this period. This includes a desire to steal intellectual property such as data relating to COVID-19 vaccine development, modelling and experimental therapeutics. It is therefore essential that healthcare providers and universities ensure they are informed, protected and prepared to respond to any cyber-threat. This article outlines key COVID-19 cyber-security principles for both healthcare organisations and academic institutions.
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.
