Background and Objectives: A hospital-based stroke registry is a useful tool for systematic analyses of the epidemiology, clinical characteristics, and natural course of stroke. Analyses of stroke registry data can provide information that can be used by health services to improve the quality of care for patients with this disease. Materials and Methods: Data were collected from the Riga East University Hospital (REUH) Stroke Registry in order to evaluate the etiology, risk factors, clinical manifestations, treatment, functional outcomes, and other relevant data for acute stroke during the period 2016–2020. Results: During a five-year period, 4915 patients (3039 females and 1876 males) with acute stroke were registered in the REUH Stroke Registry. The causative factors of stroke were cardioembolism (45.7%), atherosclerosis (29.9%), lacunar stroke (5.3%), stroke of undetermined etiology (1.2%), and stroke of other determined causes (1.2%). The most frequent localizations of intracerebral hemorrhage were subcortical (40.0%), lobar (18.9%), and brainstem (9.3%). The most prevalent risk factors for stroke were hypertension (88.8%), congestive heart failure (71.2%), dyslipidemia (46.7%), and atrial fibrillation (44.2%). In addition, 1018 (20.7%) patients were receiving antiplatelet drugs, 574 (11.7%) were taking statins, and 382 (7.7%) were taking anticoagulants. At discharge, 35.5% of the patients were completely independent (mRS (modified Rankin Scale) score: 0–2), while 49.5% required some form of assistance (mRS score: 3–5). The intrahospital mortality rate was 13.7%, although it was higher in the hemorrhage group (30.9%). Conclusions: Our stroke registry data are comparable to those of other major registries. Analysis of stroke registry data is important for improving stroke care and obtaining additional information for stroke studies.

Objectives: Stroke is a major cause of long-term disability and death worldwide. Several studies have shown that women in general have more severe symptoms at arrival to hospital and are less likely to return home and independent living. Our aim with the present study was to update previous results concerning sex differences in baseline characteristics, stroke management, and outcome in a population study from Sahlgrenska University Hospital, Gothenburg, Sweden. Methods: This study included patients with acute ischemic and hemorrhagic stroke in 2014 at Sahlgrenska University Hospital. All data were collected from The Swedish National Stroke Registry (Riksstroke). Results: The study population consisted of 1453 patients, with 46.7% females. Women were 5 years older than men. There was no sex difference in acute stroke severity. Frequency of revascularization was equal between men and women. The stroke mortality rate was the same between the sexes. At 3-months follow-up, women had a worse functional outcome and a higher frequency of depression and post-stroke fatigue. Conclusion: Our results show that there are no sex differences in management of acute stroke. However, the cause of worse functional outcome in women at 3-months follow-up, independent of other risk factors, is not clear and warrants further investigations.

Introduction: Guidelines recommend screening all stroke admissions for cognitive impairment. Delirium may be an important contributor to cognitive problems, but available data are limited by potential selection biases and imperfect delirium assessment. We aimed to describe robust estimates of delirium occurrence (incidence and prevalence) and risk factors in an acute stroke unit (ASU). Methods: We collected data from sequential admissions to our University Hospital ASU over a 20 week period (Feb-July 2016). The only exclusion was where the clinical team felt that any form of assessment was inappropriate. We aimed to perform cognitive assessments at 48 hours post stroke. Cognitive assessments were based on mini Montreal Cognitive Assessment (m-MoCA) and GP-Cog informant interview to assess for pre-stroke dementia. We assessed for delirium based on DSM-V criteria. We described univariable and multivariable associations with delirium occurrence. Results: Across the study period, 184 strokes were admitted; median age 71 years (IQR:61-79). Some form of cognitive assessment was available for 178 (97%). In total. 152 had evidence of cognitive impairment on m-MOCA, 55 (31%) met criteria for delirium and 25 (15%) had pre-stroke dementia. Significant univariable associations with delirium were:age and pre-existing cognitive decline. On logistic regression:age, history of drug or alcohol misuse and pre-stroke mRS were all independently associated with delirium. Discussion: In an unselected ASU population a substantial proportion will have cognitive impairment based on screening. Delirium is common and contributes to this cognitive problems seen in acute stroke. Independent associations with delirium occurrence were identified but were non-modifiable. Our results have implications for policy and practice. As post-stroke cognitive impairment is multifactorial, screening delirium and pre-existing cognitive issues should form part of the initial assessment.

Background. Stroke is a leading cause of death and disability worldwide. According to the Iranian Ministry of Medical Health and Education, out of 100,000 stroke incidents in the country, 25,000 lead to death. Thus, identifying risk factors of stroke can help healthcare providers to establish prevention strategies. This study was conducted to investigate the prevalence of stroke risk factors and their distribution based on stroke subtypes in Sayad Shirazi Hospital, Gorgan, Northeastern Iran. Material and Methods. A retrospective hospital-based study was conducted at Sayad Shirazi Hospital in Gorgan, the only referral university hospital for stroke patients in Gorgan city. All medical records with a diagnosis of stroke were identified based on the International Classification of Diseases, Revision 10, from August 23, 2015, to August 22, 2016. A valid and reliable data gathering form was used to capture data about demographics, diagnostics, lifestyle, risk factors, and medical history. Results. Out of 375 cases, two-thirds were marked with ischemic stroke with mean ages (standard deviation) of 66.4 (14.2) for men and 64.6 (14.2) for women. The relationship between stroke subtypes and age groups (P=0.008) and hospital outcome (P=0.0001) was significant. Multiple regression analysis showed that hypertension (Exp. (B) =1.755, P=0.037), diabetes mellitus (Exp. (B) =0.532, P=0.021), and dyslipidemia (Exp. (B) =2.325, P=0.004) significantly increased the risk of ischemic stroke. Conclusion. Overall, hypertension, diabetes mellitus, and dyslipidemia were the major risk factors of stroke in Gorgan. Establishment of stroke registry (population- or hospital-based) for the province is recommended.

Women are known to have particular heterogeneity in stroke etiology related to childbearing and hormonal factors. Although there are continued acute stroke treatment advances focusing on clot dissolution or extraction, effective secondary prevention of stroke, however, is dependent on an accurate etiological determination of the stroke. Otherwise, more strokes are likely to follow. Analysis of young women’s stroke etiology in a large stroke registry incorporating contemporary neurovascular and parenchymal imaging and cardiac imaging. Young people (18-49 years old) with stroke were consecutively accrued over a 4 year period and an investigative protocol prospectively applied that incorporated multimodality magnetic resonance imaging, angiography, cardiac echo and stroke relevant blood investigations. All patients were classified according to an expanded Trial of Org 10172 in Acute Stroke Treatment − TOAST − classification and neurological deficit by the National Institute of Health stroke admission scores. In 511 registry derived, young stroke patients (mean age 39.8 years, 95% confidence interval: 39.1; 40.7 years), gender (women n=269, 53%) the etiological categories (women; men) included: i) small vessel disease (30/55;25/55), ii) cardioembolic (16/42;26/42), iii) large vessel cervical and intracranial disease (24/43;19/43), the <em>other category</em> (132/226; 91/226), which included, iv) substance abuse (15/41; 26/41, 4.6), v) prothrombotic states (22/37;15/37), vi) dissection (11/30;19/30), vii) cerebral venous thrombosis (15/19; 4/19, 12.4), viii) vasculitis (8/12; 4/12), ix) migraine related (10/11, 1/11) and x) miscellaneous vasculopathy (38/52;14/52). The latter entities comprised of aortic arch atheroma, vessel redundancy syndrome, vertebrobasilar hypoplasia, arterial fenestrations and dolichoectasia. Some conditions occurred solely in women, such as eclampsia (5), Call Fleming syndrome (4), fibromuscular dysplasia (3) and Moya Moya syndrome (2). Categories aside from bland infarction included: ii) intracerebral hemorrhage (43/106; 63/106) and xiii) stroke of undetermined etiology (6/10; 4/10). Admission mean National Institute of Health Stroke Scale scores differed significantly between women and men (4.7; 6.0 t=1.8, P=0.03). Young women’s stroke is significantly different from men in 7/12 stroke etiological categories in addition to 4 unique subtypes that require specific management.

ABSTRACT Aiming to contribute to studies that use detailed clinical and genomic information of biobanks, we present the initial results of the first Latin American Stroke Biobank. Methods: Blood samples were collected from patients included in the Joinville Stroke Registry and four Brazilian cities. Demographic socio-economic data, cardiovascular risk factors, Causative Classification System for Ischemic Stroke, Trial of Org 10172 in Acute Stroke Treatment and National Institutes of Health scores, functional stroke status (modified Rankin) and brain images were recorded. Additionally, controls from both geographic regions were recruited. High-molecular-weight genomic DNA was obtained from all participants. Results: A total of 2,688 patients and 3,282 controls were included. Among the patients, 76% had ischemic stroke, 12% transient ischemic attacks, 9% hemorrhagic stroke and 3% subarachnoid hemorrhage. Patients with undetermined ischemic stroke were most common according the Trial of Org 10172 in Acute Stroke Treatment (40%) and Causative Classification System for Ischemic Stroke (47%) criteria. A quarter of the patients were under 55 years of age at the first-ever episode. Conclusions: We established the Joinville Stroke Biobank and discuss its potential for contributing to the understanding of the risk factors leading to stroke.

Background & Objectives: COVID-19 may influence the health seeking behavior of acute ischemic stroke patients. This study aimed to determine the characteristics of the patients who visited the emergency room in a centre designated for stroke care in Taiwan. Methods: This was a retrospective database-based study comparing the severity of ischemic stroke, intracerebral hemorrhage (ICH), and risk factors of patients seen between 2019 and 2020 in the National Taiwan University Hospital Yunlin Branch. Patients with or without thrombolysis therapy were analysed. Results: The median NIHSS of ischemic stroke patients were lower in 2019 than in 2020 (p = 0.015). The difference was seen in non-thrombolysis patients (2019: 3[1-6] vs. 4 [2-7.5], p = 0.012) but not in thrombolysis patients. The frequency of minor stroke was higher in 2019 (45.1%) than in 2020 (37.9%, p = 0.038). The discharge mRS was lower overall (p = 0.004) and in non-thrombolysis patients (0.003), but not in thrombolysis patients in 2019. As for the ICH patients, the severity of ICH score (p = 0.021) and discharge mRS (p = 0.001) were also lower in 2019. The frequencies of risk factors of stroke were higher in 2019 than in 2020, including smoking (24% vs. 18.2%, p = 0.046), alcohol (11.9% vs. 7.5%, p = 0.039), hypertension (72.9% vs. 66.2%, p = 0.039), history of stroke (16.5% vs. 11.6%, p = 0.047), and atrial fibrillation (11.9% vs. 7.5%, p = 0.039). Conclusions: This study in Taiwan revealed a decline in the willingness to seek emergency services under the influence of COVID-19 among patients with lower stroke severity, especially those with more risk factors.

Background: Despite proven efficacy of intravenous tissue plasminogen activator (tPA) and endovascular thrombectomy (EVT) in acute ischemic stroke, there has been slow administration of these therapies in the real world practice. We examined the ongoing quality improvement in acute stroke care at our comprehensive stroke center. Methods: Consecutive patients with acute ischemic stroke from 2013 to 2018 were studied. Patients were managed using Code Stroke algorithm per concurrent AHA guidelines and a simple quality improvement protocol implemented in 2015. Demographics and clinical data were collected from Get-With-The-Guideline-Stroke registry and electronic medical records. Patients were divided into 3 groups per admission and implementation date of quality improvement initiatives. Quality measures, including rates of intravenous tPA and EVT, door-to-needle (DTN) time, and door-to-puncture (DTP) time, were analyzed with general mean linear regression models and Jonckheere-Terpstra test. Results: Of the 1,369 eligible patients presenting within 24 hours of symptom onset or wakeup stroke, the rate of intravenous tPA was 20%, 30% and 22%, respectively, in 2013-2014, 2015-2016, and 2017-2018. In contrast, EVT rate was 9%, 14% and 15%, respectively. Based on Jonckheere-Terpstra test, there was significant ongoing improvement in the median DTN time (57, 45, 39 minutes; p < 0.001) and DTP time (172, 130, 114 minutes; p =0.009) during the 3 time periods, with DTN time ≤ 60 and ≤45 minutes in 80% and 63% patients, respectively, in 2017-2018. Conclusions: Getting with the guidelines and simple quality improvement initiatives are associated with satisfactory rates of acute stroke therapy and ongoing improvement in door to treatment times.

Background: As treatment of acute ischemic stroke (AIS) with IV tPA has become standard of care, smaller hospitals with limited resources have struggled to conform to consensus guidelines. To fill this practice gap, stroke systems of care were developed to support smaller, often rural, hospitals in providing standard stroke care to the patients they serve. Methods: As a result of legislative support from the Coverdell-Murphy Act, the Georgia Coverdell Acute Stroke Registry (GCASR) in collaboration with the Georgia Office of EMS (GA OEMS), the Georgia Hospital Association (GHA), and other state partners, developed a method for designating hospitals as Remote Treatment Stroke Centers (RTSC). The primary focus of performance improvement was treatment with IV tPA in eligible patients. Data collection and process change were used to improve the following quality indicators: percentage of eligible AIS patients treated with IV tPA and number of stroke alert notifications. Hospitals were required to partner with an accredited stroke center and use telemedicine to support the decision for administering IV tPA. GA OEMS was charged with reviewing and surveying individual hospitals applying for RTSC status. The GCASR served as the central repository to facilitate data sharing and benchmarking across hospitals. An inter-hospital transfer tool was created for EMS providers, adopted by GA OEMS, and disseminated throughout the state to guide management of patients receiving IV tPA who required transfer from a RTSC to an accredited stroke center. Results: Starting in 2014, pertinent information was distributed and assistance provided to the 24 RTSC eligible GCASR hospitals. At present, 4 hospitals have achieved designation; 1 hospital is pending survey; and several are considering application. In 2012-13 the now 4 RTSC hospitals gave IV tPA to 8 patients. In 2014-15 as these hospitals sought and achieved designation, this number rose to 24. During this same period, stroke alerts increased from 76 to 308. Conclusion: A state-based public health stroke initiative is effective in facilitating the designation of RTSC and thereby improving the delivery of acute stroke care in underserved areas.

Background: COVID-19 pandemic has forced important changes in health care worldwide. Stroke care networks have been affected, especially acute admissions and ancillary tests availability. We assessed the impact of the pandemic and the lockdowns imposed in stroke admissions in Latin America. Methods: A multinational study (7 countries, 18 centers) of patients admitted since the pandemic outbreak (January - June 2020). These cases were compared with the same period in 2019. We also assessed patterns during the strictest lockdown period (March-June 2020). Number of cases, stroke etiology and severity, acute care and functional outcomes were compared per periods, months, centers and countries. Results: There were 1863 stroke cases in 2019 and 1781 cases in 2020 (p=0.02). We found a significant increase in strokes of undetermined etiology due to incomplete studies in 2020 [16.8% vs 27.6%, p<0.001]). Most countries reported decreases in all-type stroke admissions, except México and Brasil (16% and 36% increases in admissions, respectively). There were no significant differences among months. All-type mortality increased (6.2% vs. 12.6%, p<0.001), and poor functional outcome (mRs 3-6) increased from 32.2% to 38.8% (p=0.007) in 2020. During the period of strict lockdown (March-June 2020), ischemic stroke admissions during the first 24 hours of onset (68.3% vs. 64.4%, p=0.1) and in-hospital stroke code activation (35.1% vs. 27.6%, p=0.005) diminished compared to 2019 period. No differences in total reperfusion treatment rates were observed, with similar door-to-needle and door-to-groin times in both periods. Conclusions: All-type stroke admissions diminished only slightly during the first months of the COVID-19 pandemic. However, in this region, we found substantial deficiencies in stroke work-up, poor short-term outcome and increased mortality.
