Epstein-Barr Virus-Associated Smooth-Muscle Tumor of the Brain.

Epstein-Barr virus, a herpesvirus, has been associated with a variety of cancers, including Burkitt, Hodgkin, and non-Hodgkin lymphomas; posttransplant lymphoproliferative disorders; gastric carcinoma; and nasopharyngeal carcinoma, in both immunocompetent and immunocompromised individuals. Previous studies have established a connection between Epstein-Barr virus and the development of smooth-muscle tumors. Smooth-muscle tumors of the brain are very rare and are often misdiagnosed as meningiomas on imaging.

Identifying gaps in the management of atrial fibrillation with anticoagulation for stroke prevention (GIANTS): a quality improvement initiative.

Objectives: Direct oral anticoagulants (DOACs) are indicated for preventing ischemic stroke in 95% of patients with atrial fibrillation (AF). However, DOACs are largely underutilized or inappropriately dosed. This study aimed to explore the rates of appropriate DOAC use between repatriated and non-repatriated patients with AF who presented with an acute ischemic stroke not deemed candidates for revascularization therapies.
