Multicenter Study Comparative StudyThe disparity in long-term survival after a first stroke in patients with and without diabetes persists: the Northern Sweden MONICA study.
Diabetes is an established risk factor for stroke. Compared to nondiabetic patients, diabetic patients also have an increased risk of new vascular events and death after stroke. We analyzed how differences in long-term survival between diabetic and nondiabetic stroke patients have changed over time, and if differences varied with respect to sex and age. ⋯ Long-term survival after a first stroke has improved in both diabetic and nondiabetic patients. Survival is markedly lower in diabetics, especially in women and younger patients, and the disparity persisted over 24 years. Decreasing the disparity in stroke survival is a challenge for stroke and diabetes care. New treatment methods in combination with intense secondary prevention in diabetic patients, especially in younger women, are needed.

Multicenter Study Comparative StudyPrediction of early stroke recurrence in transient ischemic attack patients from the PROMAPA study: a comparison of prognostic risk scores.
Several clinical scales have been developed for predicting stroke recurrence. These clinical scores could be extremely useful to guide triage decisions. Our goal was to compare the very early predictive accuracy of the most relevant clinical scores [age, blood pressure, clinical features and duration of symptoms (ABCD) score, ABCD and diabetes (ABCD2) score, ABCD and brain infarction on imaging score, ABCD2 and brain infarction on imaging score, ABCD and prior TIA within 1 week of the index event (ABCD3) score, California Risk Score, Essen Stroke Risk Score and Stroke Prognosis Instrument II] in consecutive transient ischemic attack (TIA) patients. ⋯ All published scores that do not take into account vascular imaging or prior TIA when identifying stroke risk after TIA failed to predict risk when applied by neurologists. Clinical scores were not able to replace extensive emergent diagnostic evaluations such as vascular imaging, and they should take into account unstable patients with recent prior transient episodes.

Multicenter StudyEffect of serum lipid levels on stroke outcome after rt-PA therapy: SAMURAI rt-PA registry.
The effects of lipid levels on clinical outcomes after ischemic stroke are controversial. Whether admission lipid levels and prior statin use are associated with early intracerebral hemorrhage (ICH) and long-term functional outcome after recombinant tissue plasminogen activator (rt-PA) therapy for stroke patients was investigated. ⋯ The admission HDL-C level was associated with favorable outcome 3 months after intravenous rt-PA therapy in stroke patients without cardioembolism.

Multicenter StudyThrombolysis at 3-4.5 hours after acute ischemic stroke onset--evidence from the Canadian Alteplase for Stroke Effectiveness Study (CASES) registry.
Extending the therapeutic window for thrombolysis is an important strategy in maximizing the proportion of patients treated. ECASS III examined a 3-4.5-hour window and showed a benefit to treated patients. We examined the experience in Canadian centres using intravenous tPA treatment in the 3-4.5-hour time window. ⋯ Our study suggests that patients with acute ischemic stroke may be successfully treated with intravenous tPA in the 3-4.5-hour treatment window, but cautions that later time window treatment may result in greater adverse events.

Multicenter Study Comparative StudyRisk of recurrent cerebrovascular events in patients with cryptogenic stroke or transient ischemic attack and patent foramen ovale: the FORI (Foramen Ovale Registro Italiano) study.
The optimal management of patients with cryptogenic ischemic stroke found to have a patent foramen ovale (PFO) at diagnostic workup remains unclear. The aims of this observational multicenter study were to evaluate: (1) the risk of recurrent cerebrovascular events in patients with cryptogenic minor ischemic stroke or transient ischemic attack (TIA) and PFO who either underwent percutaneous PFO closure or received only medical treatment, and (2) the risk factors associated with recurrent events. ⋯ The results of this observational, nonrandomized study suggest that PFO closure might be superior to medical therapy for the prevention of recurrent stroke. Periprocedural complications were the trade-off for this clinical benefit. Controlled randomized clinical trials comparing percutaneous closure with medical management are required.
