Efficacy and safety of thrombectomy for acute ischaemic stroke in patients with pre-stroke mRS scores of 2-3: Real-world evaluation from an open-label, prospective, multicentre, observational study
CONCLUSION: Intravenous t-PA and especially thrombectomy were safe and effective for the population with pre-stroke disabilities, particularly for patients with low NIHSS scores.PMID:37461387 | DOI:10.1177/15910199231185637

Thalamic diaschisis following perinatal stroke is associated with clinical disability
ConclusionBilateral thalamic volume changes occur after perinatal stroke. Ipsilesional volume loss is not associated with clinical motor function. Contralesional volume is inversely correlated with clinical motor function, suggesting the thalamus is involved in the known developmental plasticity that occurs in the contralesional hemisphere after early unilateral injury.

Mechanical thrombectomy is efficacious in patients with pre ‐stroke moderate disability
ConclusionPatients with pre-stroke moderate disability may benefit from MT if they are appropriately selected. This may result in fewer patients requiring nursing home placement and less financial burden on the public health system, indicating significant savings are possible.

Mobile Stoke Unit : Changes in the concept of stroke care over time.
CONCLUSIONS: The MSU allows swifter treatment and a diagnosis-based triage decision at the scene of the emergency. It is now important to continue evaluating the clinical and socioeconomic benefit of these, at first glance expensive, preclinical tools and also continue analyzing special regional aspects as well as the pros and cons of the concepts. The recently established Prehospital Stroke Treatment Organization (PRESTO) represents a promising approach. PMID: 31143974 [PubMed - as supplied by publisher]

Rapid Assessment of Acute Ischemic Stroke by Computed Tomography Using Deep Convolutional Neural Networks
This study proposes an automatic identification scheme for acute ischemic stroke using deep convolutional neural networks (DCNNs) based on non-contrast computed tomographic (NCCT) images. Our image database for the classification model was composed of 1254 grayscale NCCT images from 96 patients (573 images) with acute ischemic stroke and 121 normal controls (681 images). According to the consensus of critical stroke findings by two neuroradiologists, a gold standard was established and used to train the proposed DCNN using machine-generated image features. Including the earliest DCNN, AlexNet, the popular Inception-v3, and...

Interventional Stroke Therapy
Interventional treatment of acute ischemic stroke is currently a “very hot topic,” because acute stroke is a leading cause of disability and one of the most common causes of death worldwide. Ischemic stroke represents 80% to 85% of all strokes. Acute occlusion of cerebral arteries is the most frequent cause of ischemic stroke. Stroke mortality varies between 10% and 17% during the first month, and only about 30% of ischemic stroke patients are independent after 3 mo. Early re-canalization of the occluded brain artery is associated with a significantly higher chance of independence after 90 d and with a significant redu...

Imaging Recommendations for Acute Stroke and Transient Ischemic Attack Patients: A Joint Statement by the American Society of Neuroradiology, the American College of Radiology, and the Society of NeuroInterventional Surgery WHITE PAPER
SUMMARY: Stroke is a leading cause of death and disability worldwide. Imaging plays a critical role in evaluating patients suspected of acute stroke and transient ischemic attack, especially before initiating treatment. Over the past few decades, major advances have occurred in stroke imaging and treatment, including Food and Drug Administration approval of recanalization therapies for the treatment of acute ischemic stroke. A wide variety of imaging techniques has become available to assess vascular lesions and brain tissue status in acute stroke patients. However, the practical challenge for physicians is to understand t...

Mimics of Acute Stroke: Tips and Tricks for Solving the Diagnostic Dilemma
Stroke affects approximately 800,000 people in the United States each year and is the fourth major leading cause of adult mortality.1 Rapid diagnostic evaluation and prompt treatment are important to prevent death and disability from a stroke. The literature suggests that up to 30% of patients who present with acute onset of neurologic symptoms were found to have a stroke misdiagnosis. In addition, the safety of thrombolytic therapy for stroke mimics has not been fully studied. Although patients with acute stroke can benefit substantially from thrombolytic therapy, misdiagnosis of acute stroke can carry serious implication...

Diffusion tensor imaging as a prognostic biomarker for motor recovery and rehabilitation after stroke
ConclusionRecovery of motor function probably involves remodeling of the CST proper and/or a greater reliance on alternative motor tracts through spontaneous and treatment-induced plasticity. DTI-metrics represent promising clinical biomarkers to predict motor recovery and to monitor and predict the response to neurorehabilitative interventions.

Economic and Societal Aspects of Stroke Management
Stroke is a major health burden worldwide with attendant mortality, morbidity, and cost. In 2010, there were approximately 16.9 million strokes and an estimated 33 million stroke survivors worldwide. Also, in the United States, stroke is the third leading cause of death, with ischemic stroke resulting in 8% 30-day mortality (20% for hemorrhagic stroke). The staggering economic cost of the disease is driven largely by disability and long term care. Efforts in stroke healthcare delivery are focusing on performance, efficiency and value to better serve the consumer.

Efficacy of recanalization therapy for ischemic stroke: multicenter hospital network experience
DiscussionThe inter-company agreement between Federico II University and several peripheral hospitals allows an absolute and relative increase in endovascular mechanical thrombectomy and intravenous thrombolysis procedures, with a relative prevalence of mechanical thrombectomy. A regional implementation of the stroke multi-disciplinary care system is hardly needed to ensure the optimum treatment for the largest number of patients, improving patient ’s outcome.

Patterns of Visual Task-based Functional MRI Activation in Chronic Posterior Cerebral Artery Stroke Patients
ConclusionIn chronic PCA stroke patients with residual visual impairments, the brain attempts to recruit more neighboring and distant functional areas for executing the impaired visual skill. This intense recruitment pattern in poorly recovering patients appears to be a  sign of failed compensation. Consequently, fMRI has the potential for clinically relevant prognostic assessment in patients surviving PCA stroke; however, as this study included no longitudinal data, this potential should be further investigated in longitudinal imaging studies, with a larger coho rt, and multiple time points.

Mechanical recanalization in acute stroke : Torture or choice.
[Mechanical recanalization in acute stroke : Torture or choice.] Radiologe. 2013 Feb 24; Authors: Berlis A Abstract CLINICAL/METHODICAL ISSUE: Stroke is the third most common cause of death in the developed world and the leading cause of disability worldwide. The present demographic development will lead to increased numbers of stroke patients in the future. STANDARD RADIOLOGICAL METHODS: Patient selection takes place by using various computer tomographic (CT) or magnetic resonance (MR) imaging modalities. For endovascular stroke treatment a modern biplane angiography suite is re...

Assessment of ischemic penumbra in patients with hyperacute stroke using amide proton transfer (APT) chemical exchange saturation transfer (CEST) MRI
Chemical exchange saturation transfer (CEST)‐derived, pH‐weighted, amide proton transfer (APT) MRI has shown promise in animal studies for the prediction of infarction risk in ischemic tissue. Here, APT MRI was translated to patients with acute stroke (1–24 h post‐symptom onset), and assessments of APT contrast, perfusion, diffusion, disability and final infarct volume (23–92 days post‐stroke) are reported. Healthy volunteers (n = 5) and patients (n = 10) with acute onset of symptoms (0–4 h, n = 7; uncertain onset <24 h, n = 3) were scanned with diffusion‐ and perfusion‐weighted...
