Burden and Outcome of Prevalent Ischemic Brain Disease in a National Acute Stroke Registry Clinical Sciences
Conclusions— In our national cohort of patients with acute ischemic stroke, nearly two thirds had a prior overt stroke or subclinical stroke. Risk of poor functional outcomes was increased for patients with prior stroke, both overt and subclinical.

Pulmonary Embolism in Ischemic Stroke: Clinical Presentation, Risk Factors, and Outcome Stroke
Conclusions In this large cohort study, PE occurred in nearly 1% of AIS patients. PE was more common in patients with severe stroke, history of cancer, previous DVT/PE or acute DVT and associated with lower short- and long-term survival, greater disability, and longer length of stay.

Clinical Utility of Electronic Alberta Stroke Program Early Computed Tomography Score Software in the ENCHANTED Trial Database Clinical Sciences
Background and Purpose—Clinical utility of electronic Alberta Stroke Program Early CT Score (e-ASPECTS), an automated system for quantifying signs of infarction, was evaluated in a large database of thrombolyzed patients with acute ischemic stroke.Methods—All baseline noncontrast computed tomographic scans of patients with anterior circulation acute ischemic stroke who participated in the alteplase dose arm of the randomized controlled trial ENCHANTED (Enhanced Control of Hypertension and Thrombolysis Stroke Study) were reviewed; poor quality and large (>6 mm) slice thickness were excluded. Included scans had e-ASPECTS...

Effect of Right Insular Involvement on Death and Functional Outcome After Acute Ischemic Stroke in the IST-3 Trial (Third International Stroke Trial) Clinical Sciences
Conclusions—We found an association between right insular involvement and higher odds of death and worse functional outcome. The difference between right- and left-sided insular lesions on outcomes seemed to be most evident for mild/moderate strokes.Clinical Trial Registration—URL: http://www.isrctn.com. Unique identifier: ISRCTN25765518.

Successful Reperfusion With Mechanical Thrombectomy Is Associated With Reduced Disability and Mortality in Patients With Pretreatment Diffusion-Weighted Imaging-Alberta Stroke Program Early Computed Tomography Score
Background and Purpose—In acute ischemic stroke patients, diffusion-weighted imaging (DWI)–Alberta Stroke Program Early Computed Tomography Score (ASPECTS) is correlated with infarct volume and is an independent factor of functional outcome. Patients with pretreatment DWI-ASPECTS ≤6 were excluded or under-represented in the recent randomized mechanical thrombectomy trials. Our aim was to assess the impact of reperfusion in pretreatment DWI-ASPECTS ≤6 patients treated with mechanical thrombectomy.Methods—We analyzed data collected between January 2012 and August 2015 in a bicentric prospective clinical registry of...

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 ...

Stroke Size Correlates with Functional Outcome on the Simplified Modified Rankin Scale Questionnaire
Background: Acute stroke size is one of the factors impacting functional outcome. To further validate the simplified modified Rankin Scale questionnaire (smRSq), we tested its correlation with stroke size.Methods: We screened 60 ischemic stroke patients with acute brain images available for stroke volume measurement who were enrolled in 2 smRSq reliability studies. Inclusion criteria were acute ischemic stroke visible on computed tomography (CT) or magnetic resonance imaging (MRI) and the smRSq scored at least 3 months after stroke. We excluded patients with disabilities from a previous stroke. One investigator who was bli...

Quality indicators in acute stroke care: a prospective observational survey in 13 Italian regions.
CONCLUSIONS: Our data confirm the need of quality monitoring in stroke care. Although SU patients showed a better adherence to quality indicators, overall compliance was unsatisfactory. PMID: 24293350 [PubMed - as supplied by publisher]

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’...

Value of Whole Brain Computed Tomography Perfusion for Predicting Outcome After TIA or Minor Ischemic Stroke
About 15% of patients with transient ischemic attack (TIA) or minor ischemic stroke have functional impairment after 3 months. We studied the role of whole brain computed tomography perfusion (WB-CTP) in the emergency diagnosis of TIA or minor stroke in predicting disability at 3 months.

Stroke: management and prevention
Cerebrovascular disease can be devastating for patients and their families, but much can be done to attenuate cerebral damage and reduce disability. Active intervention is in three phases: acute therapy, rehabilitation and secondary prevention. Thrombolysis within 4.5 hours of symptom onset substantially reduces morbidity from ischaemic stroke with no overall impact on mortality. Administration requires the use of clear protocols to rapidly triage, transport and investigate patients. Computed tomography remains an appropriate imaging technique in the early assessment of most stroke patients.

Stroke Dysbiosis Index (SDI) in Gut Microbiome Are Associated With Brain Injury and Prognosis of Stroke
Conclusions: We developed an index to measure gut microbiota dysbiosis in stroke patients; this index was significantly correlated with patients' outcome and was causally related to outcome in a mouse model of stroke. Our model facilitates the potential clinical application of gut microbiota data in stroke and adds quantitative evidence linking the gut microbiota to stroke. Introduction Ischemic stroke imposes a heavy burden on society, with 24.9 million cases worldwide (1). Although intravenous thrombolysis and endovascular treatment greatly improve some patients' prognosis, the prognosis for most 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...

Stroke treatment, outcomes improve at hospitals participating in UCLA-led initiative
Administering a clot-dissolving drug to stroke victims quickly — ideally within the first 60 minutes after they arrive at a hospital emergency room — is crucial to saving their lives, preserving their brain function and reducing disability. Given intravenously, tPA (tissue plasminogen activator) is currently the only Food and Drug Administration–approved therapy shown to improve outcomes for patients suffering acute ischemic stroke, which affects some 800,000 Americans annually. Now, a UCLA-led study demonstrates that hospitals participating in the "Target: Stroke" national quality-improvement program have markedly...
