Background Direct oral anticoagulants (DOACs) are recommended over vitamin K antagonists (VKAs) for stroke prevention in patients with non-valvular atrial fibrillation (NVAF). However, real-world prescribing patterns and dosing appropriateness in low- and middle-income countries remain poorly characterized. This study evaluated patterns of oral anticoagulant use and identified clinical determinants of suboptimal prescribing in a tertiary cardiovascular center in Vietnam.

Underexploited Vietnamese macroalgae could provide clean-label antioxidant and antimicrobial ingredients for food systems, yet selective and scalable extraction remains challenging. Here, probe ultrasonic-assisted extraction (UAE-H) using aqueous ethanol was benchmarked against soaking, Soxhlet and ultrasonic bath extraction for Porphyra vietnamensis. UAE-H delivered the highest phenolic recovery and antioxidant responses and was subsequently optimized using response surface methodology.
