High folic acid supplementation associated with higher rates of COVID-19 infections and mortality

A new study found that people taking high doses of folic acid were 1.5 times more likely to get COVID-19 and 2.6 times more likely to die from the virus compared to those not on folic acid supplements. Methotrexate, an antifolate drug, mitigated this negative impact when given with folic acid.

Old drugs hint at new ways to beat chronic pain

A newly identified link between chronic pain and lung cancer in mice suggests that old drugs such as clonidine, capsaicin, and fluphenazine may offer new treatments for chronic pain. The study found that blocking the BH4 pathway reduced pain sensitivity and decreased tumor growth in mouse models of KRAS-driven lung cancer.
