Review Comparative Study
Early assessments of dysphagia and aspiration risk in acute stroke patients.
Dysphagia is common after stroke and is a marker of poor prognosis. Early identification is important. This article reviews the merits and limitations of various assessment methods available to clinicians. ⋯ Although bedside tests remain an important early screening tool for dysphagia and aspiration risk, further refinements are needed to improve their accuracy.

Review Meta Analysis Comparative Study
Duplex ultrasound and magnetic resonance angiography compared with digital subtraction angiography in carotid artery stenosis: a systematic review.
The purpose of this work was to review and compare published data on the diagnostic value of duplex ultrasonography (DUS), MR angiography (MRA), and conventional digital subtraction angiography (DSA) for the diagnosis of carotid artery stenosis. ⋯ These results suggest that MRA has a better discriminatory power compared with DUS in diagnosing 70% to 99% stenosis and is a sensitive and specific test compared with DSA in the evaluation of carotid artery stenosis. For detecting occlusion, both DUS and MRA are very accurate.

Obtaining viable informed consent from stroke patients for participation in clinical trials of acute stroke therapies is often problematic because of patients' neurological deficits. Furthermore, obtaining permission from surrogates is often not possible or not legally permissible. ⋯ Acute stroke researchers should consider conducting clinical trials with an exception from the informed consent requirement permitted by this law.
