Introduction: The pediatric direct oral anticoagulation (DOAC) trials provide an opportunity to evaluate and characterize challenges in their design and execution to inform future antithrombotic trials.

Objective: To perform a systematic review of pediatric DOAC trials for the treatment of venous thromboembolism to critically appraise their methodology and understand the feasibility and challenges.

Methods: Systematic search of MEDLINE, EMBASE, the Cochrane Library and ClinicalTrials.

Machine Learning-Assisted Biomass-Derived Carbon Dots as Fluorescent Sensor Array for Discrimination of Warfarin and Its Metabolites.

Langmuir

January 2025

School of Pharmacy, Key Laboratory of Innovative Drug Development and Evaluation, Hebei Medical University, Shijiazhuang, Hebei 050017, China.

Warfarin (WAR), an effective oral anticoagulant, is of utmost importance in treating many diseases. Despite its significance, rapid and precise discrimination of WAR remains a formidable challenge, especially facing its structural analogs of metabolites. Here, three kinds of herb-derived N-doped carbon dots (NCDs) were greenly synthesized via a fast and simple microwave-assisted method.

Objective: Atrial fibrillation (AF) is a common arrhythmia associated with a five-fold increased risk of stroke. Family physicians (FPs) serve as the primary contact point for patients seeking healthcare. While many surveys have assessed FPs' knowledge on AF across various countries, no such study has been conducted in Türkiye.

: Direct oral anticoagulants (DOACs) are frequently used to prevent embolism in atrial fibrillation. Gastrointestinal bleeding is frequent, but its drug-specific characteristics remain unclear. This study examined the frequency and characteristics of gastrointestinal bleeding in patients with nonvalvular atrial fibrillation for different DOACs.

Article Synopsis
  • Clinical atrial fibrillation (AF) significantly raises the risk of stroke and systemic embolism, but treatment with oral anticoagulants can lower this risk while increasing the chance of major bleeding.
  • Device-detected atrial fibrillation (DDAF) also poses a stroke risk, though lower than clinical AF, with studies showing that direct oral anticoagulation can reduce stroke risk for DDAF patients but similarly heightens bleeding risk.
  • The challenge persists in determining how to effectively manage the balance between reducing thromboembolic risk and the increased risk of bleeding for DDAF patients, as well as identifying those who would benefit most from anticoagulant therapy.
