Vaginal birth may be safer for pregnant women with kidney and liver transplants

A new study found that pregnant women with kidney or liver transplants can safely undergo trial of labor without increased risk to themselves or their babies. In fact, vaginal births resulted in improved outcomes for the baby without compromising maternal health. Conversely, cesarean births were associated with higher risks of complica...

Income inequality can harm children’s achievement in maths – but not reading, 27-year study suggests

A 27-year study suggests that income inequality is linked to lower maths scores among US children, with even richer students experiencing negative effects. The study found that states with higher income gaps saw poorer maths results, while reading grades were not associated with income inequality. Policymakers may need to consider redu...

Study: Those under 40 are more likely than older adults to recover COVID-related smell and taste loss

A VCU study found that 4 out of every 5 COVID-19 survivors regain their sense of smell and taste within six months, with younger adults more likely to recover. Those with nasal congestion are more likely to recover their sense of smell, while those with head injuries or shortness of breath have a lower likelihood.

A protein causes significantly higher risk of severe cancer progression for men

A research team at TUM has discovered that the protein TIMP1 is associated with a significantly higher risk of liver metastasis and death in male patients, particularly those with pancreatic, colon, and melanoma cancers. This finding may lead to improved diagnosis and targeted therapy options for men.
