Prehospital Notification Using a Mobile Application Can Improve Regional Stroke Care System in a Metropolitan Area
CONCLUSION: The FASTroke app is an easy and useful tool for prenotification as a regional stroke care system in the metropolitan area, leading to reduced transport and acute ischemic stroke management time and more reperfusion treatment. The effect was more significant when the preregistration was performed jointly.PMID:34904406 | DOI:10.3346/jkms.2021.36.e327

Early identification of ischemic stroke in noncontrast computed tomography
Publication date: July 2019Source: Biomedical Signal Processing and Control, Volume 52Author(s): Guoqing Wu, Jixian Lin, Xi Chen, Zeju Li, Yuanyuan Wang, Jing Zhao, Jinhua YuAbstractEarly identification of stroke is critical for the treatment and subsequent recovery. Non-contrast computed tomography (ncCT) is a routinely employed imaging modality for stroke evaluation. However, the early identification of stroke in ncCT images is very difficult, since there are subtle differences between lesion and healthy tissue during the hyperacute phase. In this paper, an image patch classification-based method was developed to detect ...

The dynamics of soluble Fas/APO 1 apoptotic biochemical marker in acute ischemic stroke patients.
Conclusion: Study results confirmed the dynamic pattern of sFas/APO 1 in serum and cerebrospinal fluid of patients with acute ischemic stroke, suggesting the possible role of apoptosis in the pathogenesis of cerebral infarction. PMID: 24277959 [PubMed - as supplied by publisher]

Ipsilateral internal carotid artery web and acute ischemic stroke: A cohort study, systematic review and meta-analysis
In this study, we aim to determine the prevalence of ipsilateral carotid web in a cohort of ischemic stroke patients and to perform a systematic review and meta-analysis of similar cohorts. Patients& methodsWe performed a retrospective, observational, cohort study of acute ischemic stroke patients admitted to a comprehensive stroke center from June 2012 to September 2017. Carotid web was defined on computed tomography angiography (CTA) as a thin shelf of non-calcified tissue immediately distal to the carotid bifurcation. We described the prevalence of carotid artery webs in our cohort, then performed a systematic review an...

Clinical-CT mismatch defined NIHSS ≥ 8 and CT-ASPECTS ≥ 9 as a reliable marker of candidacy for intravenous thrombolytic therapy in acute ischemic stroke
by Hung-Ming Wu, I-Hui Lee, Chao-Bao Luo, Chih-Ping Chung, Yung-Yang Lin BackgroundClinical-diffusion mismatch between stroke severity and diffusion-weighted imaging lesion volume seems to identify stroke patients with penumbra. However, urgent magnetic resonance imaging is sometimes inaccessible or contraindicated. Thus, we hypothesized that using brain computed tomography (CT) to determine a baseline “clinical-CT mismatch” may also predict the responses to thrombolytic therapy. MethodsBrain CT lesions were measured using the Alberta Stroke Program Early CT Score (ASPECTS). A total of 104 patients were included: 79 pa...

Early computed tomography-based scores to predict decompressive hemicraniectomy after endovascular therapy in acute ischemic stroke
by Ilko L. Maier, Daniel Behme, Marlena Schnieder, Ioannis Tsogkas, Katharina Schregel, Mathias B ähr, Michael Knauth, Jan Liman, Marios-Nikos Psychogios BackgroundIdentification of patients requiring decompressive hemicraniectomy (DH) after endovascular therapy (EVT) is crucial as clinical signs are not reliable and early DH has been shown to improve clinical outcome. The aim of our study was to identify imaging-based scores to predict the risk for space occupying ischemic stroke and DH. MethodsProspectively derived data from patients with acute large artery occlusion within the anterior circulation and EVT was analyzed ...

Association between carotid artery perivascular fat density and cerebral small vessel disease
In conclusion, our study provides evidence suggesting that an increased pericarotid fat density is associated with the presence and degree of WMHs and lacunes. Our findings suggested that features that appear to extend beyond the vessel lumen of the ICA may be linked to CSVD.PMID:34289452 | DOI:10.18632/aging.203327

Efficacy of a four-tier infection response system in the emergency department during the coronavirus disease-2019 outbreak
This study presents an efficient method to prevent the degradation of the quality of diagnosis and treatment of other critical diseases during the pandemic. MethodsWe performed a retrospective observational study. The primary outcome was ED length of stay (ED LOS). The secondary outcomes were the door-to-balloon time in patients with suspected ST-segment elevation myocardial infarction and door-to-brain computed tomography time for patients with suspected stroke. The outcome measures were compared between patients who were treated in the red and orange zones designated as the changeable isolation unit and those who were tr...

Sensitivity of Hyperdense Basilar Artery Sign on Non-Enhanced Computed Tomography
Conclusion In patients with clinically suspected acute BAO the combination of visual assessment and additional attenuation measurement with a cut-off value of 46.5 HU is a reliable approach with high sensitivity in the detection of BAO on NECT.
