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.

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.

Comparative Study
Association of the endogenous nitric oxide synthase inhibitor ADMA with carotid artery intimal media thickness in the Framingham Heart Study offspring cohort.
Higher plasma concentrations of the endogenous nitric oxides synthase inhibitor asymmetrical dimethylarginine (ADMA) are associated with increased risk of cardiovascular and cerebrovascular events and death, presumably by promoting endothelial dysfunction and subclinical atherosclerosis. We hypothesized that plasma ADMA concentrations are positively related to common carotid artery intimal-media thickness (CCA-IMT) and to internal carotid (ICA)/bulb IMT. ⋯ In our large community-based sample, we observed that higher plasma ADMA concentrations were associated with greater ICA/bulb IMT, but not with CCA-IMT. These data are consistent with the notion that ADMA promotes subclinical atherosclerosis in a site-specific manner, with a greater proatherogenic influence at known vulnerable sites in the arterial tree.

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.

Anosmia frequently occurs after aneurysmal subarachnoid hemorrhage not only after clipping, but also after endovascular coiling. Thus, at least in part, anosmia is caused by the hemorrhage itself and not only by surgical treatment. However, it is unknown whether anosmia is related to rupture of the aneurysm with sudden increase in intracranial pressure or to the presence of blood in the basal cisterns. Therefore, we studied the prevalence of anosmia in patients with nonaneurysmal perimesencephalic hemorrhage. ⋯ Anosmia occurs in one of every 16 patients with perimesencephalic hemorrhage, which is lower than previously reported rates after coiling in patients with subarachnoid hemorrhage but higher than rates after coiling for unruptured aneurysms. These data suggest that blood in the vicinity of the olfactory nerves plays a role in the development of anosmia.
