Randomized Controlled Trial Multicenter Study
TESPI (Thrombolysis in Elderly Stroke Patients in Italy): a randomized controlled trial of alteplase (rt-PA) versus standard treatment in acute ischaemic stroke in patients aged more than 80 years where thrombolysis is initiated within three hours after stroke onset.
Intravenous (i.v.) thrombolysis with recombinant tissue-Plasminogen Activator (rt-PA) (alteplase) within three hours from symptom onset is the only approved treatment of pharmacological revascularization in acute ischaemic stroke. However, the current license limits the use of rt-PA to patients aged ≤80 years due to the lack of evidence of safety and efficacy of this treatment in the elderly from randomized clinical trials. This article describes the design of the Thrombolysis in Elderly Stroke Patients in Italy (TESPI) trial planned to fill the lack of controlled data on i.v. thrombolysis in this age category of stroke patients. ⋯ The primary efficacy end-point is the disability at day 90, dichotomized as a favourable outcome (modified Rankin Scale 0-2) or unfavourable outcome (modified Rankin Scale 3-6). The main primary safety end-point is symptomatic intracerebral haemorrhage defined as any hemorrhage at the 22-36 h post-treatment scan combined with neurological deterioration leading to an increase of one or more points at the National Institutes of Health Stroke Scale. The TESPI trial, with the protocol number FARM65KNKY, is registered in the European Union Drug Regulating Authorities Clinical Trials database with the number 2007-006177-88 and in the Stroke Trials Registry of the Washington University Internet Stroke Center.

Multicenter Study
Thrombolytic therapy for acute ischemic stroke after recent transient ischemic attack.
Safety and efficacy of intravenous thrombolysis in stroke patients with recent transient ischemic attack are hotly debated. Patients suffering transient ischemic attack may present with diffusion-weighted imaging lesions, and although normal computed tomography would not preclude thrombolysis, the concern is that they may be at higher risk for hemorrhage post-thrombolysis treatment. Prior ipsilateral transient ischemic attack might provide protection due to ischemic preconditioning. We assessed post-thrombolysis outcomes in stroke patients who had prior transient ischemic attack. ⋯ Transient ischemic attack preceding ischemic stroke does not appear to have a major influence on outcomes following thrombolysis. Patients with prior ipsilateral transient ischemic attack appear not to be at higher risk of bleeding complications.

Randomized Controlled Trial Multicenter Study
Cooling in intracerebral hemorrhage (CINCH) trial: protocol of a randomized German-Austrian clinical trial.
Intracerebral hemorrhage accounts for up to 15% of all strokes and is frequently associated with poor functional outcome and high mortality. So far, there is no clear evidence for a specific therapy, apart from general stroke unit or neurointensive care and management of secondary complications. Promising experimental and pilot clinical data support the use of therapeutic hypothermia after intracerebral hemorrhage. ⋯ The results of Cooling in IntraCerebral Hemorrhage trial are believed to directly influence future therapy of large intracerebral hemorrhage.

Randomized Controlled Trial Multicenter Study
A multicentre, randomized, double-blinded, placebo-controlled Phase III study to investigate EXtending the time for Thrombolysis in Emergency Neurological Deficits (EXTEND).
Thrombolytic therapy with tissue plasminogen activator is effective for acute ischaemic stroke within 4·5 h of onset. Patients who wake up with stroke are generally ineligible for stroke thrombolysis. We hypothesized that ischaemic stroke patients with significant penumbral mismatch on either magnetic resonance imaging or computer tomography at three- (or 4·5 depending on local guidelines) to nine-hours from stroke onset, or patients with wake-up stroke within nine-hours from midpoint of sleep duration, would have improved clinical outcomes when given tissue plasminogen activator compared to placebo. ⋯ The primary outcome measure will be modified Rankin Scale 0-1 at day 90. Clinical secondary outcomes include categorical shift in modified Rankin Scale at 90 days, reduction in the National Institutes of Health Stroke Score by 8 or more points or reaching 0-1 at day 90, recurrent stroke, or death. Imaging secondary outcomes will include symptomatic intracranial haemorrhage, reperfusion and or recanalization at 24 h and infarct growth at day 90.

Randomized Controlled Trial Multicenter Study
A cluster randomized controlled trial of a structured training programme for caregivers of inpatients after stroke (TRACS).
The majority of stroke patients are discharged home dependent on informal caregivers, usually family members, to provide assistance with activities of daily living, including bathing, dressing, and toileting. Many caregivers feel unprepared for this role, and this may have a detrimental effect on both the patient and caregiver. ⋯ The primary outcomes are extended activities of daily living for the patient and caregiver burden measured at six-months after recruitment. Secondary outcomes include mood and cost-effectiveness, with final follow-up at 12 months.
