A new meta-analysis in HeartRhythm found that SGLT2 inhibitors reduced sudden cardiac death risk by about 18% across patients with type 2 diabetes, heart failure, or chronic kidney disease, with consistent effects and minimal trial variation. A Cochrane review of over 100,000 participants showed RSV vaccines are highly effective and safe: protein-based shots cut severe lower respiratory infections in older adults by ~75% and protected infants when given to pregnant mothers, halving RSV-related care and hospitalizations. Finally, WHO and EMA reaffirmed acetaminophen’s safety in pregnancy, rejecting suggested links to autism or neurodevelopmental harm, noting decades of safe use and the risks of untreated pain or fever.
