In acute stroke patients treated with intravenous tissue plasminogen activator (t-PA), early recanalization of occluded arteries can improve the clinical outcome. The magnetic susceptibility effect of deoxygenated hemoglobin in red thrombi can present as hypointense signals on T2*-weighted gradient echo imaging. We investigated whether the gradient echo imaging M1 susceptibility vessel sign (M1 SVS) can predict no early recanalization after t-PA infusion. ⋯ The M1 SVS on T2* appears to be a strong predictor for no early recanalization after t-PA therapy.

Randomized Controlled Trial Comparative Study
The erythropoietin neuroprotective effect: assessment in CABG surgery (TENPEAKS): a randomized, double-blind, placebo controlled, proof-of-concept clinical trial.
Neurocognitive dysfunction complicates coronary artery bypass surgery. Erythropoietin may be neuroprotective. We sought to determine whether human recombinant erythropoietin would reduce the incidence of neurocognitive dysfunction after surgery. ⋯ This study demonstrates feasibility and safety for the use of human recombinant erythropoietin as a neuroprotectant in coronary artery bypass graft surgery. A trend in the reduction of neurocognitive dysfunction at 2 months was associated with erythropoietin use. A multicenter randomized controlled trial is warranted.

Little is known about the contribution of obesity to the higher mortality risk among stroke survivors. We assessed the independent association between body mass index (BMI) and mortality among stroke survivors. ⋯ Higher BMI after stroke is associated with a greater risk of all-cause and cardiovascular death among younger individuals. Younger stroke survivors may especially benefit from more vigorous efforts to monitor and treat obesity.

Comparative Study
Open-angle glaucoma and the risk of stroke development: a 5-year population-based follow-up study.
Although open-angle glaucoma (OAG) is associated with some of the risk factors of stroke development, there is still no published study addressing whether OAG increases the risk of stroke development. We investigated the risk of stroke development after a diagnosis of OAG. ⋯ Patients with OAG demonstrated a significantly increased risk of stroke development during the 5-year follow-up period.
