Escalated single Platelet Inhibition for one month plus Direct oral anticoagulation in patients with Atrial fibrillation and acUte coRonary syndrome undergoing percutaneoUS coronary intervention (EPIDAURUS): A randomized-controlled trial

The EPIDAURUS randomized-controlled trial was prematurely terminated due to safety concerns, revealing that adding potent P2Y12-inhibitors (prasugrel or ticagrelor) to direct oral anticoagulants in patients with atrial fibrillation and acute coronary syndrome significantly increased bleeding risks without providing a clear reduction in ischemic events compared to a clopidogrel-based regimen.

Equality of Poor Outcomes in Laryngotracheal Stenosis: A 20-Year South African Study

This 20-year South African study reveals that in a resource-constrained setting, universal health-system delays and socioeconomic factors did not create outcome disparities for laryngotracheal stenosis patients because system-wide constraints led to an "equality of poor outcomes," where clinical success was instead determined primarily by disease aetiology and comorbidities rather than diagnostic or treatment delays.
