Multicenter StudyDysphagia in Patients with Acute Ischemic Stroke: Early Dysphagia Screening May Reduce Stroke-Related Pneumonia and Improve Stroke Outcomes.
Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. ⋯ Dysphagia exposes stroke patients to a higher risk of pneumonia, disability, and death, whereas an EDS seems to be associated with reduced risk of stroke-related pneumonia and disability.

Comparative StudyMulti-Contrast High-Resolution Magnetic Resonance Findings of Spontaneous and Unruptured Intracranial Vertebral Artery Dissection: Qualitative and Quantitative Analysis According to Stages.
Although high-resolution magnetic resonance imaging (HR-MRI) has been used as a strong imaging method for diagnosing intracranial vertebral artery dissection (IVAD), the diagnosis is sometimes challenging because a dissection has geometric changes in the natural course. The radiologic features may change or disappear over time, which makes the diagnosis confusing. Our study was to present radiological findings according to the stages in spontaneous and unruptured, IVAD on 3T HR-MRI and to guide the age estimation of IVAD with the distinguishing findings according to the stages. ⋯ The 3T HR-MRI reveals the vessel wall characteristics and provides distinguishing findings between earlier stages and the chronic stage in spontaneous and unruptured IVAD. Characterization of these radiological findings according to stages may assist with the age estimation of the dissection and may help to understand IVAD as a whole.

Observational StudyAdverse Events Following International Normalized Ratio Reversal in Intracerebral Hemorrhage.
Prothrombin complex concentrates (PCCs) are frequently used to reverse the effect of vitamin K antagonists (VKAs) in patients with non-traumatic intracerebral hemorrhage (ICH). However, information on the rate of thromboembolic events (TEs) and allergic events after PCC therapy in VKA-ICH patients is limited. ⋯ Overall, INR reversal with PCC appears safe. Though no clear relationship between higher PCC dosing and TEs was observed, PCC doses between >2,000 and 3,000 IU and higher morbidity at ICH onset were associated with TEs. Hence, individual titration of PCC to avoid exposure to unnecessarily high doses using point-of-care devices should be prospectively explored.

Randomized Controlled Trial Multicenter StudyEarly Blood Pressure Reduction in Acute Ischemic Stroke with Various Severities: A Subgroup Analysis of the CATIS Trial.
Clinical trials have generally showed a neutral effect of blood pressure (BP) reduction on clinical outcomes among acute ischemic stroke patients. We conducted a prespecified subgroup analysis to assess whether disease severity modifies the effect of early antihypertensive treatment on death and disability among patients with acute ischemic stroke. ⋯ Early BP reduction with antihypertensive medications did not reduce or increase the risk of death, major disabilities, recurrent instances of stroke, and vascular events in acute ischemic stroke patients with a variety of disease severities.

The Mechanism of Procedural Stroke Following Carotid Endarterectomy within the Asymptomatic Carotid Surgery Trial 1.
Understanding the pathophysiological mechanism of procedural stroke during carotid intervention may help reduce the risk of stroke in those undergoing surgery. We therefore studied the features of procedural strokes within the first Asymptomatic Carotid Surgery Trial-1 (ACST-1) to identify the underlying pathophysiological mechanism. ⋯ In ACST-1, the risk of procedural stroke was low. Most strokes (60%) occurred on the day of the procedure and were caused by thrombosis or thrombotic occlusion of the ipsilateral carotid artery. These findings emphasize the importance of immediate assessment of the treated carotid artery when a stroke occurs after CEA.
