Pregnant women with COVID-19 face higher risk of pre-eclampsia, study shows

A review of scientific literature found pregnant women infected by SARS-CoV-2 have a higher risk of developing pre-eclampsia due to reduced ACE2 availability. ACE2 plays a crucial role in placental development, blood pressure control, and fetal development, making its impairment more susceptible to serious complications.

Exposure to tobacco smoke in early life is associated with accelerated biological ageing

A new study finds that early-life exposure to tobacco smoke is associated with accelerated biological ageing in children. The analysis of over 1,000 children in six European countries revealed that maternal tobacco smoke during pregnancy and indoor exposure to black carbon are linked to an acceleration in epigenetic ageing.
