Stroke; a journal of cerebral circulation

Stroke patients often report that primary care physicians (PCPs) are their first medical contact after onset of symptoms. We studied PCP attitudes and current practice in early management of suspected stroke patients. ⋯ Stroke and transient ischemic attack were well recognized as medical emergencies by PCPs in our study. However, only two-thirds of PCP would immediately admit stroke suspected patients with clear symptoms to hospital as medical emergency.

An increased risk of hemorrhagic transformation is a major factor limiting the use of tissue plasminogen activator for stroke. Increased hemorrhagic transformation is also found in animals undergoing transient focal cerebral ischemia with hyperglycemia; this study examined whether hyperbaric oxygen (HBO) could reduce such hemorrhagic transformation in a rat model. ⋯ Early intraischemic HBO treatment reduces the blood-brain barrier disruption, hemorrhagic transformation, and mortality after focal cerebral ischemia suggesting that HBO could be used to reduce hemorrhagic conversion in patients with stroke.

Basilar artery occlusion (BAO) is a stroke subtype with poor prognosis, but recanalizing therapies have been reported to be effective. We investigated whether initial admission to telemedically linked general hospitals with subsequent stroke-center transfer is related to poorer outcome than direct admission to stroke centers. ⋯ BAO patients who were admitted primarily to community hospitals had a worse prognosis. Patients with typical symptoms should have direct access to stroke centers, or may need bridging therapies.

Weekend admissions are associated with higher in-hospital mortality. However, limited information is available concerning the "weekend effect" on stroke mortality. Our aim was to evaluate the impact of weekend admissions on stroke mortality in different settings. ⋯ Stroke patients admitted on weekends had a higher risk-adjusted mortality than did patients admitted on weekdays. Disparities in resources, expertise, and healthcare providers working during weekends may explain the observed differences in weekend mortality.

Acute basilar artery occlusion portends high risk of stroke and death. Thrombolysis or endovascular therapy has been limited to patients who present within hours of symptom onset. Without recanalization, acute basilar artery occlusion almost always results in death or severe disability. ⋯ Endovascular therapy can be feasible and safe for symptomatic basilar artery occlusion at chronic stage.
