The study also found a weaker link between theory of mind and popularity for boys, highlighting potential gender differences in social interactions.
A meta-analysis published in The Lancet found that longer dual antiplatelet therapy (DAPT) after drug-eluting stent (DES) implantation was associated with increased mortality. Shorter DAPT, on the other hand, was linked to lower rates of all-cause and non-cardiac mortality, as well as reduced risk of major bleeding.
A review of evidence suggests a possible increase in mortality with no clear benefit when using the anti-clotting drug alteplase more than 3 hours after stroke. The current guidance is based on uncertain evidence, and researchers are urging for a re-evaluation of data to guide policy decisions.
