Anticoagulation Protocol for Secondary Prevention of Acute Ischemic Stroke Associated with Nonvalvular Atrial Fibrillation.

Objectives: There is no clear evidence regarding when to initiate oral anticoagulants (OACs) for secondary prevention of recurrent stroke in patients with atrial fibrillation (AF). Therefore, this study aimed to evaluate the safety and efficacy of a novel OAC initiation protocol for secondary prevention of acute ischemic stroke associated with AF.

Materials And Methods: In this multicenter prospective study 597 consecutive Japanese patients with acute ischemic stroke associated with nonvalvular AF received post-stroke OACs according to a protocol based on severity (clinical (NIHSS) and radiological (ASPECTS + W)), rt-PA use, reperfusion, and hemorrhagic transformation (HT).

Preoperative Predictive Factors of Short-Term Outcome in Idiopathic Normal Pressure Hydrocephalus.

Background: Surgical treatment of idiopathic normal pressure hydrocephalus (iNPH) by ventriculoperitoneal (VP) or lumboperitoneal (LP) shunting can achieve long-term recovery of activities of daily living; however, in a subset of patients, maintenance of independence lasted for <6 months. This study examined positive preoperative predictive factors of short-term outcome for shunted iNPH patients.

Methods: Over a 9-year period, consecutive patients from multiple centers diagnosed with probable iNPH underwent either VP or LP shunt surgery.
