Multicenter StudyIs cognitive functioning 1 year poststroke related to quality of life domain?
Previous studies on the association between poststroke cognitive impairment and quality of life (QoL) have shown divergent results. In this study, we investigated the relationships between cognitive functioning and various QoL domains at 1 year poststroke. This was a cross-sectional study, examining 92 patients at 1 year poststroke. ⋯ Controlling for demographic factors and motor impairments resulted in negligible percentages of variance additionally explained by cognitive functioning. The percentages of explained variance were somewhat lower in the analyses with the separate cognitive domains and not significant for depression. Poor cognitive functioning was associated with reduced functional independence, social participation, depressive mood, and life satisfaction 1 year post; however, motor impairment was a stronger determinant of long-term QoL than cognitive functioning.

Randomized Controlled Trial Multicenter StudyNeurosurgical outcomes after intracerebral hemorrhage: results of the Factor Seven for Acute Hemorrhagic Stroke Trial (FAST).
The value of neurosurgical interventions after spontaneous intracerebral hemorrhage (SICH) is uncertain. We evaluated clinical outcomes in patients diagnosed with SICH within 3 hours of symptom onset who underwent hematoma evacuation or external ventricular drainage (EVD) of the hematoma in the Factor Seven for Acute Hemorrhagic Stroke Trial (FAST). FAST was a randomized, multicenter, double-blind, placebo-controlled trial conducted between May 2005 and February 2007 at 122 sites in 22 countries. ⋯ ICH volume was substantially decreased in patients who underwent hematoma evacuation between 24 and 72 hours after hospital admission, and this was associated with better clinical outcome. In conclusion, a small number of patients who underwent neurosurgery in FAST exhibited no overall clinical benefit from neurosurgical intervention, although outcomes varied by type of surgery, time of surgery, and hematoma location. Our findings support the need for further research into the value of neurosurgery in patients with SICH.

Case ReportsVenous cerebral infarction in a patient with peripheral hemodialysis shunt and occlusion of the left brachiocephalic vein.
Intracranial venous congestion is a rare condition in hemodialysis patients with central venous occlusion. We report a patient with cerebral venous infarction resulting from high reflex flow into the cranium induced by an arteriovenous hemodialysis shunt in the arm and occlusion of the brachiocephalic vein. This case illustrates that abnormal extracranial venous circulation should be considered when cerebral venous congestion is assumed to produce neurologic symptoms in patients with an arteriovenous shunt.
