Abstract
INTRODUCTION Rural residency has been associated with lower reperfusion treatment rates for acute ischemic stroke in many countries. We aimed to explore urban-rural differences in IV thrombolysis rates in a small country with universal health care, and short transport times to stroke units. PATIENTS AND METHODS In this nationwide cohort study, adult ischemic stroke patients registered in the Danish Stroke Registry (DSR) between 2015 and 2020 were included. The exposure was defined by residence rurality. Data from the DSR, Statistics Denmark, and the Danish Health Data Authority, were linked on the individual level using the Civil Registration Number. Adjusted treatment rates were calculated by balancing baseline characteristics using inverse probability of treatment weights. RESULTS Among the included 56,175 patients, prehospital delays were shortest for patients residing in capital municipalities (median 4.7 h), and longest for large town residents (median 7.1 h). Large town residents were predominantly admitted directly to a comprehensive stroke center (98.5%), whereas 30.9% of capital residents were admitted to a hospital with no reperfusion therapy available (non-RT unit). Treatment rates were similar among all non-rural residents (18.5%-18.7%), but slightly lower among rural residents (17.2% [95% CI 16.5-17.8]). After adjusting for age, sex, immigrant status, and educational attainment, rural residents reached treatment rates comparable to capital and large town residents at 18.5% (95% CI 17.7-19.4). DISCUSSION AND CONCLUSION While treatment rates varied minimally by urban-rural residency, substantial differences in median prehospital delay and admission to non-RT units underscored marked urban-rural differences in potential obstacles to reperfusion therapies.

Abstract
OBJECTIVES To determine hospital-level factors associated with thrombectomy uptake. MATERIALS AND METHODS The Nationwide Emergency Department Sample was retrospectively queried to determine the total number of thrombectomies performed based on different hospital characteristics. Joint point analysis was used to determine which years were associated with significant increases in the number of high-volume thrombectomy centers (ostensibly defined as >50 thrombectomies/year), thrombectomy-capable centers (>15 thrombectomies/year), and total number of thrombectomies performed. Multivariable logistic regression was used to determine hospital factors associated with having an increased odds of performing thrombectomies, and of being classified as a high-volume thrombectomy or a thrombectomy-capable center. RESULTS Between 2007-2020 there was a stepwise increase in the number of thrombectomy-capable and high-volume thrombectomy centers in the United States. In 2020, there were a total of 15,705 thrombectomies performed, with 89 high-volume thrombectomy centers, and 359 thrombectomy-capable centers. The number of thrombectomy-capable centers significantly increased after 2011. After 2013 and 2016 there was a significant change in the growth rate of high-volume thrombectomy centers. There was also a significant increase in the total number of thrombectomies performed after 2016. Hospital characteristics that were associated with an increased likelihood of being classified as thrombectomy-capable or high-volume included trauma level 1 and 2 hospitals. CONCLUSIONS Between 2007 and 2020, there was a marked growth in thrombectomy utilization for acute ischemic stroke. This growth outpaced new diagnoses of ischemic stroke, and was driven largely by certain hospital types, with the greatest rises following seminal publications of positive randomized thrombectomy trials.

Abstract
Background and objective The rate of intravenous thrombolysis (IVT) in acute ischemic stroke (AIS) is still low due to several absolute and relative contraindications, including admission time delay, which remains the main reason for exclusion from thrombolysis. In this study, we aimed to identify reasons for non-thrombolysis at our stroke center. Methods This retrospective study included all patients with a final diagnosis of AIS as per our stroke prospective register from 2014 to 2019. Reasons for non-thrombolysis were analyzed for all AIS and for patients admitted within 4.5 hours from symptom onset. From 2014 to 2016, a non-contrast CT scan was the unique imaging modality used to decide on performing IVT. In 2017, CT angiography was added to the imaging protocol. Results Among 3,562 patients with AIS, 3,365 (94.4%) were excluded from thrombolysis; 2,871 (80.6%) were admitted out of the IVT time window, which represents the main reason for exclusion from thrombolysis. Thrombolysis alert (TA) was triggered for 691 (19.4%) patients, and 197 patients had IVT (which represents 28.5% of TA and 5.5% of all AIS). Minor stroke and rapidly improving symptoms of stroke were also reasons for non-thrombolysis, which explain the high-average initial National Institutes of Health Stoke Scale (NIHSS) score of more than 12 in the thrombolysis group. CT angiography allows for the analysis of the supra-aortic trunks, the circle of Willis, and the collateral status. Therefore, during the period when a CT angiography scan was used, there were more IVTs for minor strokes, rapidly improving strokes, and AIS patients admitted beyond the IVT time window. Conclusions This study highlights the common reasons for exclusion from thrombolysis. Efforts should be undertaken to avoid admission time delays. Also, based on our findings, minor stroke and improving stroke no longer represent absolute contraindications for IVT in AIS.

Abstract
Stroke is a leading cause of death and disability. Some patients may present with atypical symptoms. One of the very rare presentations of stroke is initial neurogenic pain. Rare painful presentations include, amongst others, acute trigeminal neuralgia, atypical facial pain, hemi-sensory pain, and episodic pain. Based on the available literature, the pain at presentation may be episodic, transient, or persistent, and it may herald other debilitating stroke symptoms such as hemiparesis. Pain quality is often described as burning; less often as sharp. Patients often have accompanying focal symptoms and findings on neurological examination. However, in several of the reviewed cases, these were discrete or non-existent. In patients with pain located in the trunk and/or extremities, lesions may involve the thalamus, lateral medulla oblongata, insula, or parietal lobe. In patients with atypical facial or orbital pain (including the burning "salt and pepper" sensation), the stroke lesions are typically located in the pons. In this narrative review, we included studies/case series of patients who had pain at the time of onset, shortly before or within 24 h of stroke symptoms (on the day of admission). Cases with pain related to aortic or cervical vessel dissection, cerebral venous sinus thrombosis, subarachnoid hemorrhage, reversible cerebral vasoconstriction syndrome, and CNS vasculitis were excluded. With this review, we aim to summarize the current knowledge on stroke presenting with acute pain.

Abstract
Background and objectives: The time interval between stroke onset and hospital arrival is a major barrier for reperfusion therapies in acute ischemic stroke and usually accounts for most of the onset-to-treatment delay. The present study aimed to analyze the pre-hospital delays for patients with acute ischemic stroke admitted to a tertiary stroke center in Romania and to identify the factors associated with a late hospital arrival. Material and methods: The study population consisted of 770 patients hospitalized with the diagnosis of acute ischemic stroke in the University Emergency Hospital Bucharest during a 6-month period, between 1 January and 30 June 2018. Data regarding pre-hospital delays were prospectively collected and analyzed together with the demographic and clinical characteristics of the patients. Results: In total, 31.6% of patients arrived at the hospital within 4.5 h from stroke onset and 4.4% in time intervals between 4.5 and 6 h from the onset, and 28.7% of the patients reached the hospital more than 24 h after onset of symptoms. Transport to hospital by own means was the only factor positively associated with arrival to hospital > 4.5 h from stroke onset and more than doubled the odds of late arrival. Factors negatively associated with hospital arrival > 4.5 h after stroke onset were prior diagnosis of atrial fibrillation, initial National Institute of Health Stroke Scale (NIHSS) score ≥ 16 points, presence of hemianopsia, facial palsy and sensory disturbance. Factors increasing the odds of hospital arrival after 24 h from stroke onset were living alone and living in rural areas. Conclusions: Almost one in three ischemic stroke patients presenting to our center reaches hospital more than 24 h after onset of symptoms. These findings highlight the need for urgent measures to improve not only stroke awareness but also pre-hospital protocols in order to provide timely and appropriate care for our stroke patients.

Abstract
Objectives Thrombolytic treatment in acute ischemic stroke (AIS) reduces stroke‐related disability. Nearly 40% of all patients with AIS (<4.5 h) receive thrombolysis, but there is a large variation in the use between hospitals. Little is known about reasons and predictors for not giving thrombolytic treatment. Therefore, we aimed to investigate reasons for non‐thrombolysis in patients admitted within 4.5 h. Methods All patients with AIS (<4.5 h) admitted to Akershus University Hospital, Norway, between January 2015 and December 2017 were examined. Patient characteristics and reasons for not giving thrombolysis were registered. Descriptive statistics and logistic regression analyses were performed. Results Of 535 patients admitted with AIS (<4.5 h), 250 (47%) did not receive thrombolysis and of these only 26% had an absolute contraindication to treatment. Among the 74% with relative contraindications, the most common reasons given were mild and improving symptoms. Previous stroke (OR 3.32, 95%CI 1.99–5.52), arriving between 3 h and 4.5 h after onset (OR 7.76, 95%CI 3.73–16.11) or having mild symptoms (OR 2.33, 95%CI 1.56–3.49) were all significant predictors of not receiving thrombolytic treatment in the multivariable logistic regression model. Conclusion A large proportion of patients with AIS do not receive thrombolysis. This study highlights up‐to‐date findings that arriving late in the time window, mild symptoms, and previous stroke are strong predictors of non‐treatment. It is uncertain whether there is an underuse of thrombolysis in AIS. Increasing the utility of thrombolysis in the 4.5 h time window must be weighed against possible harms.

Abstract
National Institutes of Health Stroke Scale (NIHSS) is the most validated clinical scale for stroke recognition, severity grading, and symptom monitoring in acute care and hospital settings. Numerous modified prehospital stroke scales exist, but these scales contain less clinical information and lack compatibility with in-hospital stroke scales. In this real-life study, we aimed to investigate if NIHSS conducted by paramedics in the field is a feasible and accurate prehospital diagnostic tool.

Abstract
BACKGROUND The increasing stroke burden, inequity in the distribution of local neurologists, and the recent signing of the Universal Health Care Law in the Philippines provide compelling reasons for policy-makers to devise strategies to establish networks between primary care and stroke-ready hospitals. In this review, we explored the current literature and evidence that emphasized the roles of primary care providers (PCPs) and specialists, care transition, and telemedicine/teleneurology in various stages of stroke management. REVIEW SUMMARY Clear delegation of stroke care responsibilities among PCPs and specialists is needed. Due to the limited number of specialists/neurologists, PCPs may contribute to addressing the insufficiency of community knowledge of acute stroke symptoms/risk factors, coordination with specialists and stroke-ready hospitals during acute stroke, and continuity of care during the poststroke stage. At present, the Philippines has only 49 stroke-ready hospitals; thus, an efficient and functional referral system for the care transition between the PCPs and specialists must be organized in our country. To provide remote access to expert stroke care for underserved areas and to increase thrombolysis utilization, the establishment of an effective telestroke system is indispensable. The empowerment of PCPs in teleneurology may assist in strengthening communication and networking with specialists with the ultimate goal of improving patient outcomes. CONCLUSIONS In the era of Universal Health Care in the Philippines, the roles of PCP and specialists must be delineated. Increased access to stroke care through the establishment of networks among PCPs and stroke-ready hospitals (ie, via effective transition of care/teleneurology) must be prioritized especially in resource-constrained settings.

Abstract
BACKGROUND Stroke awareness is known to influence treatment seeking and risk reduction behavior, but there is limited data from Sri Lanka and South Asia. AIM To describe stroke awareness in incident stroke patients and to compare with patients without stroke and/or ischemic heart disease (IHD) in a Sri Lankan tertiary-care center. METHODS We studied awareness of stroke in all incident stroke patients admitted to a tertiary-care center in Sri Lanka and compared with a group of age- and sex-matched patients without stroke and/or IHD, over 2 years. Knowledge on stroke mechanisms, risk factors, symptoms, prognosis, treatment, and prevention were evaluated using a 40-item interviewer-administered questionnaire and converted to a composite score of 100%. Total awareness was categorized as Very poor (<24%), Poor (25%-49%), Good (50%-74%), and Very good (>74%). RESULTS One hundred and sixty four incident stroke patients (mean age 62.0 ± 11.5 years; 64.6% males) and 164 patients without stroke and/or IHD were studied. Mean stroke awareness was 47.79% ± 14.6 in stroke patients, and 47.73% ± 14.9 in the nonstroke and/or IHD patients (P = .95). Of the associations studied, better stroke awareness (>50%) was associated only with higher education levels (OR 1.90, 95%CI 1.33-2.72, P < .001) in stroke patients. CONCLUSIONS Stroke awareness is not satisfactory in incident stroke patients and is no better than in patients without stroke and/or IHD. Better stroke awareness was associated with higher education levels.

Abstract
BACKGROUND AND PURPOSE We investigated the effectiveness of intravenous thrombolysis (IVT) in acute ischaemic stroke (AIS) patients with large vessel or distal occlusions and mild neurological deficits, defined as National Institutes of Health Stroke Scale scores < 6 points. METHODS The primary efficacy outcome was 3-month functional independence (FI) [modified Rankin Scale (mRS) scores 0-2] that was compared between patients with and without IVT treatment. Other efficacy outcomes of interest included 3-month favorable functional outcome (mRS scores 0-1) and mRS score distribution at discharge and at 3 months. The safety outcomes comprised all-cause 3-month mortality, symptomatic intracranial hemorrhage (ICH), asymptomatic ICH and severe systemic bleeding. RESULTS We evaluated 336 AIS patients with large vessel or distal occlusions and mild stroke severity (mean age 63 ± 15 years, 45% women). Patients treated with IVT (n = 162) had higher FI (85.6% vs. 74.8%, P = 0.027) with lower mRS scores at hospital discharge (P = 0.034) compared with the remaining patients. No differences were detected in any of the safety outcomes including symptomatic ICH, asymptomatic ICH, severe systemic bleeding and 3-month mortality. IVT was associated with higher likelihood of 3-month FI [odds ratio (OR), 2.19; 95% confidence intervals (CI), 1.09-4.42], 3-month favorable functional outcome (OR, 1.99; 95% CI, 1.10-3.57), functional improvement at discharge [common OR (per 1-point decrease in mRS score), 2.94; 95% CI, 1.67-5.26)] and at 3 months (common OR, 1.72; 95% CI, 1.06-2.86) on multivariable logistic regression models adjusting for potential confounders, including mechanical thrombectomy. CONCLUSIONS Intravenous thrombolysis is independently associated with higher odds of improved discharge and 3-month functional outcomes in AIS patients with large vessel or distal occlusions and mild stroke severity. IVT appears not to increase the risk of systemic or symptomatic intracranial bleeding.

Utilization of Intravenous Tissue Plasminogen Activator and Reasons for Nonuse in Acute Ischemic Stroke in Saudi Arabia. J Stroke Cerebrovasc Dis 2020; 29:104761. [PMID: 32173225 DOI: 10.1016/j.jstrokecerebrovasdis.2020.104761] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 01/11/2020] [Accepted: 02/14/2020] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Recombinant tissue plasminogen activator (rt-PA, alteplase) within 4.5 hours of symptom onset decreases the rate of disability after acute ischemic stroke (AIS). Due to various reasons, alteplase remains underutilized in certain regions (∼3% in low- and middle-income countries). AIMS We aimed to estimate the alteplase utilization rate and identify the reasons for nonuse in Saudi Arabia. METHODS We retrospectively reviewed all patients admitted with suspected stroke in the past 24 hours to the stroke unit at King Abdulaziz Medical City, Riyadh, Saudi Arabia from February 2016 to July 2018. We estimated the alteplase utilization rate among patients with AIS who could be treated within 4.5 hours of symptoms onset (≤225 minutes, allowing 45 minutes for door to needle time). We examined potential predictors of alteplase use using multivariable logistic regression analyses. Study was approved by local IRB. RESULTS Of 1366 patients with suspected stroke, 819 (60%) had AIS. The alteplase utilization rates were 8.6% and 29% for all AIS and AIS arrived within the therapeutic window, respectively. The most common reason for no alteplase treatment was late arrival. Only 244 (29.8%) of AIS patients arrived within the time window for treatment. Among patients with sudden neurological deficit who arrived within the therapeutic time window, the most common reasons were mild neurological deficit (National Institutes of Health Stroke Scale score <5, 29.9%), stroke mimics (16.6%), and hemorrhagic stroke (8.1%). CONCLUSIONS Our study showed a comparable alteplase utilization rate with most international estimates. The low utilization rate was mainly attributed to late patient arrival. Urgent interventions are needed to improve public awareness of stroke recognition and prehospital stroke care.

Abstract
INTRODUCTION Intravenous thrombolysis is not suitable for patients undergoing oral anticoagulants therapy, with INR > 1.7 or PT > 15 s. We described a case of intravenous thrombolysis in a patient with INR 1.9. PATIENT CONCERNS A 66-year-old female patient was diagnosed with acute appendicitis complicated with atrial fibrillation. Seven days after admission, the patient suffered mixed aphasia with right limb asthenia. The NIHSS score was 11 points. and early infarction and hemorrhagic manifestations were not found in the emergency head CT. Thirty minutes after the onset of symptoms, NIHSS of patient increased from 11 to 14, but the INR was 1.92. DIAGNOSIS Acute ischemic stroke. INTERVENTIONS The IT therapy was recommended and all the therapy related risks were explained to the patient's parents. Briefly, the patient was given rTPA 38.5 mg. In addition to intravenous thrombolysis, VitK1 40 mg was simultaneously administered. OUTCOME The patient's symptoms of drowsiness were improved. After 24 hours, all symptoms were stabilized with NIHSS of 2 points, there was a slight language obstruction, and no hemorrhagic transformation in head CT. Three months later, the review showed MRS score of 0, and the patient could take care of herself in daily life. CONCLUSION The clinical guidelines are still the main reference for guiding clinical practice, and the main thrombolytic standards and contraindications for treatment still need to be conformed. On this basis, for individualized patients, clinicians must accurately judge the cause of acute stroke, to make optimal choice, reduce disability and mortality, and improve quality of life of patients.

Abstract
OBJECTIVE. The objective of this study was to assess the accuracy and reliability of IV thrombolysis recommendations made after interpretation of head CT images of patients with symptoms of acute stroke displayed on smartphone or laptop reading systems compared with those made after interpretation of images displayed on a medical workstation monitor. MATERIALS AND METHODS. This retrospective study was institutional review board-approved, and the requirement for informed consent was waived. We used a factorial design including 2256 interpretations (188 patients, four neuroradiologists, and three reading systems). To evaluate the reliability, we calculated the intraobserver and interobserver agreements using the intraclass correlation coefficient (ICC) and the following interpretation variables: hemorrhagic lesions, intraaxial neoplasm, stroke dating (acute, subacute, and chronic), hyperdense arteries, and infarct size assessment. Accuracy equivalence tests were performed for the IV thrombolysis recommendation; for this variable, sensitivity, specificity, and ROC curves were evaluated. RESULTS. Good or very good interobserver and intraobserver agreements were obtained after interpretation of each variable. The IV thrombolysis recommendation showed very good interobserver agreements (ICC ≥ 0.85) and very good intraobserver agreements (ICC ≥ 0.81). For the IV thrombolysis recommendation, the AUC values (0.83-0.84) and sensitivities (0.94-0.95) were equivalent among all the reading systems at a 5% equivalent threshold. CONCLUSION. Our study found that mobile devices are reliable and accurate to help stroke teams to decide whether to administer IV thrombolysis in patients with acute stroke.

Abstract
BACKGROUND In acute ischemic stroke patients, telestroke technology provides sustainable approaches to improve the use of thrombolysis therapy. How this is achieved as it relates to inclusion or exclusion of clinical risk factors for thrombolysis is not fully understood. We investigated this in a population of hypertensive stroke patients. METHODS Structured data from a regional stroke registry that contained telestroke and non telestroke patients with a primary diagnosis of acute ischemic stroke with history of hypertension were collected between January 2014 and June 2016. Clinical risk factors associated with inclusion or exclusion for recombinant tissue plasminogen activator (rtPA) in the telestroke and non telestroke were identified using multiple regression analysis. Associations between variables and rtPA in the regression models were determined using variance inflation factors while the fitness of each model was determined using the ROC curve to predict the power of each logistic regression model. RESULTS The non telestroke admitted more patients (62% vs 38%), when compared with the telestroke. Although the telestroke admitted fewer patients, it excluded 11% and administered thrombolysis therapy to 89% of stroke patients with hypertension. In the non telestroke group, adjusted odd ratios showed significant associations of NIH stroke scale score (OR = 1.059, 95% CI, 1.025-1.093, P < 0.001) and coronary artery disease (OR = 2.003, 95% CI, 1.16-3.457, P = 0.013) with inclusion, while increasing age (OR = 0.979, 95% CI, 0.961-0.996, P = 0.017), higher INR (OR = 0.146, 95% CI, 0.032-0.665, P = 0.013), history of previous stroke (OR = 0.39, 95% CI, 0.223-0.68, P = 0.001), and renal insufficiency (OR = 0.153, 95% CI, 0.046-0.508, P = 0.002) were associated with rtPA exclusion. In the telestroke, only direct admission to the telestroke was associated with rtPA administration, (OR = 4.083, 95% CI, 1.322-12.611, P = 0.014). CONCLUSION The direct admission of hypertensive stroke patients to the telestroke network was the only factor associated with inclusion for thrombolysis therapy even after adjustment for baseline variables. The telestroke technology provides less restrictive criteria for clinical risk factors associated with the inclusion of hypertensive stroke patients for thrombolysis.

Abstract
BACKGROUND AND AIMS Monitoring the quality of acute ischemic stroke (AIS) management is increasingly important since patient outcome could be improved with better access to evidence-based treatments. In this scenario, the aim of our study was to identify thrombolysis rate, reasons for undertreatment, and factors associated with better outcome. METHODS From January to December 2016, individuals diagnosed with AIS at the Policlinic San Martino Hospital in Genoa, Italy, were prospectively included. Severity of stroke, site of occlusion, rate and time related in-hospital management of systemic thrombolysis, and mechanical thrombectomy were recorded. Safety and clinical outcomes were compared between different subgroups. RESULTS Of 459 AIS patients (57.3% females, mean age 78.1), 111 received i.v. thrombolysis (24.4%) and 50 received mechanical thrombectomy (10.9%). Apart from arrival behind the therapeutic window, which was the first limitation to thrombolysis, the main reason of undertreatment was minor stroke or stroke in rapid improvement. Baseline NIHSS ≥ 8 was associated with unfavorable clinical outcome (mRS > 2) (OR 20.1; 95% CI, 1.1-387.4, p = 0.047). Age older than 80 years (OR 5.0; 95% CI, 1.4-64.1, p = 0.01), baseline NIHSS ≥ 7 (OR 20.1; 95% CI, 1.1-387.4, p = 0.047), and symptomatic intracranial hemorrhage (OR 22.9; 95% CI, 2.0-254.2, p = 0.01) proved independently associated with mortality. CONCLUSIONS i.v. thrombolysis and mechanical thrombectomy rate was higher than that of previous reports. Minor stroke or stroke in rapid improvement was a major reason for exclusion from thrombolysis of eligible patients. Higher NIHSS proved an independent predictor of unfavorable clinical outcome and death. Strategies to avoid in-hospital delays need to be enforced.

Abstract
OBJECTIVES Acute stroke management has changed dramatically over the recent years, where a timely assessment is driven by the expanding treatment options of acute ischaemic stroke. This increases the risk in treating non-stroke patients (stroke mimics) with a possibly hazardous intravenous thrombolysis treatment (IVT). SETTING Patients of the thrombolysis registry of Södersjukhuset AB, a secondary health centre in Stockholm, were retrospectively studied to determine complications and outcome after IVT in strokes and stroke mimics. PARTICIPANTS Consecutively, 674 recruited patients from 1 January 2008 to 1 December 2013 were analysed regarding demographics and outcome at 3 months after onset of symptoms. RESULTS Ischaemic stroke was confirmed in 625 patients (93%), and 48 patients (7%) were stroke mimics. Patients with strokes were older than stroke mimics 72 (IQR: 64-81) vs 54 years (IQR 40-67), p<0.0001. Antihypertensive and antithrombotic treatment were more common in patients with stroke (p<0.0001 and p=0.006, respectively). National Institute of Health Stroke Scale did not differ at time of presentation. Excellent outcome defined as modified Rankin Scale score 0-1, at 3 months, was less common in stroke than in stroke mimics (50% vs 87.5%, p<0.0001). No stroke mimic had a symptomatic intracerebral haemorrhage. Age of less than 40 years may be a predictor for a patient to be a stroke mimic (OR: 8.7, 95% CI: 3.2 to 24.0, p<0.0001). CONCLUSIONS Stroke mimics receiving IVT had a more favourable outcome compared with patients with stroke, and showed no haemorrhagic complications. Age below 40 years may be a predictor for stroke mimics.
