Low Levels of Caveolin-1 Predict Symptomatic Bleeding After Thrombolytic Therapy in Patients With Acute Ischemic Stroke Brief Report
Background and Purpose—Experimental models of cerebral ischemia demonstrate that the decrease in the caveolin-1 membrane protein results in an increase in endothelial permeability. Because this phenomenon is responsible for hemorrhagic transformation (HT) after cerebral ischemia, we aimed to determine whether caveolin-1 levels may predict bleeding after recombinant tissue-type plasminogen activator (r-tPA) administration in patients with acute stroke.Methods—We studied 133 patients with a first hemispheric stroke treated with r-tPA within 4.5 hours of symptom onset. HT was evaluated and classified on cranial computed t...

World Stroke Organization Global Stroke Services Guidelines and Action Plan
Every two seconds, someone across the globe suffers a symptomatic stroke. ‘Silent’ cerebrovascular disease insidiously contributes to worldwide disability by causing cognitive impairment in the elderly. The risk of cerebrovascular disease is disproportionately higher in low to middle income countries where there may be barriers to stroke care. The last two decades have seen a major transformation in the stroke field with the emergence of evidence‐based approaches to stroke prevention, acute stroke management, and stroke recovery. The current challenge lies in implementing these interventions, particularly in regions ...

The effect and associated factors of dispatcher recognition of stroke: A retrospective observational study.
CONCLUSIONS: The dispatchers should spend more time identifying stroke patients by following the dispatch protocol. Recognition of stroke by dispatchers was associated with improved stroke care. PMID: 29158105 [PubMed - as supplied by publisher]

Thrombolysis Despite Recent Stroke: A Case Series Brief Reports
Conclusions— In our center, we thrombolysed 6 patients despite recent stroke. Three patients had asymptomatic petechial hemorrhagic transformation within the area of subacute infarct, without apparent neurological worsening. Prospective studies are needed to explore the possible safety of tissue-type plasminogen activator in the context of previous subacute stroke in otherwise eligible patients.

Initial Body Temperature in Ischemic Stroke: Nonpotentiation of Tissue-Type Plasminogen Activator Benefit and Inverse Association With Severity Clinical Sciences
Conclusions— In patients with hyperacute stroke, higher presenting temperatures are associated with less severe neurological deficits and reduced final infarct volumes. Presenting temperature does not modify the benefit of tPA on 3-month favorable outcome.

Should minor stroke patients be thrombolyzed? A focused review and future directions
Stroke is a leading cause of morbidity and mortality worldwide. Up to 80% of ischemic stroke patients may initially present with minor symptoms. Minor stroke and transient ischemic attack patients are typically treated conservatively with antiplatelet agents and general vascular prevention strategies. Yet a high proportion develop recurrent stroke or progression of stroke and up to one in four of these patients are disabled or dead at follow‐up. Minor or rapidly improving symptoms are the top reasons for withholding thrombolytic therapy to time‐eligible stroke patients as they are believed to be ‘too good to treat’...

Predictive Factors for Early Clinical Improvement after Intra-arterial Thrombolytic Therapy in Acute Ischemic Stroke
This study aimed to identify clinical and radiological variables that are predictive of early improvement (EI) after IAT in acute ischemic stroke.Methods: This single-center retrospective cohort study included 141 consecutive patients who underwent IAT for terminal internal carotid and/or middle cerebral artery (MCA) occlusions. EI was defined as a National Institutes of Health Stroke Scale (NIHSS) score less than 3 or NIHSS score improvement of 8 points or more within 72 hours of IAT. The EI and non-EI groups were compared in terms of clinical and radiological findings before and after IAT.Results: Forty-nine patients sh...

Ischemic Stroke in Evolution: Predictive Value of Perfusion Computed Tomography
Background: Various perfusion computed tomography (PCT) parameters have been used to identify tissue at risk of infarction in the setting of acute stroke. The purpose of this study was to examine predictive value of the PCT parameters commonly used in clinical practice to define ischemic penumbra. The patient selection criterion aimed to exclude the effect of thrombolysis from the imaging data.Methods: Consecutive acute stroke patients were screened and a total of 18 patients who initially underwent PCT and CT angiogram (CTA) on presentation but did not qualify to receive thrombolytic therapy were selected. The PCT images ...

Time to ct scan imaging after symptom onset among ischeamic stroke patients presenting to a quaternary hospital in ghana
This study sought to determine the time of onset of symptoms to the time a CT imaging was done among patients presenting with acute stroke at the Korle-Bu Teaching Hospital.

Is Door-to-Needle Time Reduced for Emergency Medical Services Transported Stroke Patients Routed Directly to the Computed Tomography Scanner on Emergency Department Arrival?
A nationally recommended practice to accelerate thrombolytic therapy for acute ischemic stroke is to route emergency medical services (EMS)-transported stroke patients directly to the computed tomography (CT) scanner on arrival. We evaluated door-to-needle time with direct-to-CT routing versus emergency department (ED)-bed first routing.

Intravenous Thrombolysis in Posterior Circulation Stroke
Conclusions: Up to date, no data about PCIS and IVT are available from RTCs. Based on limited results from retrospective clinical studies and case series, IVT is safer for use in PCIS than in ACIS. Patients with brainstem ischemia, vertebral artery occlusion, and absence of basilar or posterior cerebral artery occlusion could be considered for treatment with IVT even in borderline cases. Time to IVT in PCIS seems to be a less crucial factor than in ACIS. IVT for PCIS may be beneficial even after 4.5 h from symptom onset.

Frequency of Hemorrhage on Follow Up Imaging in Stroke Patients Treated With rt-PA Depending on Clinical Course
Conclusions: Frequency of hemorrhagic transformation in Routine follow-up brain imaging and consecutive changes in therapeutic management were different depending on clinical course measured by NHISS score. Introduction Brain imaging 24–36 h after systemic thrombolysis for acute ischemic stroke is recommended in American Stroke Association and European Stroke Organization guidelines (1, 2). Brain imaging is performed to detect secondary bleeding or hemorrhagic transformation in order to adapt medical stroke prevention if necessary. Guideline recommendations are based on the results of the first study on rt-PA...

Influence of Sex on Stroke Prognosis: A Demographic, Clinical, and Molecular Analysis
Conclusion Our data suggest that women who suffer from IS present with a poorer functional outcome than men at 3-months, regardless of other preclinical and clinical factors during the acute phase. These relationships seem to be mediated by atrial dysfunction and inflammation. The inflammatory response is slightly higher in women; however, there are no sex differences in their functional behavior. There is a probable relationship between the molecular marker of atrial dysfunction NT-proBNP and worse functional outcome in women, and the connection seems to be more important in cardioembolic stroke patients. In patients wi...
