Background and Objectives: Acute ischemic cardioembolic stroke (CS) is a clinical condition with a high risk of death, and can lead to dependence, recurrence, and dementia. Materials and Methods: In this study, we evaluated gender differences and female-specific clinical data and early outcomes in 602 women diagnosed with CS from a total of 4600 consecutive acute stroke patients in a single-center hospital stroke registry over 24 years. A comparative analysis was performed in women and men in terms of demographics, cerebrovascular risk factors, clinical data, and early outcomes. Results: In a multivariate analysis, age, hypertension, valvular heart disease, obesity, and internal capsule location were independent variables associated with CS in women. The overall in-hospital mortality rate was similar, but the group of women had a greater presence of neurological deficits and a higher percentage of severe limitation at hospital discharge. After the multivariate analysis, age, altered consciousness, limb weakness, and neurological, respiratory, gastrointestinal, renal, cardiac and peripheral vascular complications were independent predictors related to early mortality in women. Conclusions: Women with CS showed a differential demographic and clinical profile and worse early outcomes than men. Advanced age, impaired consciousness, and medical complications were predictors of stroke severity in women with CS. [ABSTRACT FROM AUTHOR]

Background: Intracranial hemorrhage (ICH) carries a significant morbidity and mortality burden; however, there is scarce information in Latin American. Objective: To analyze the functional prognosis and mortality rates among participants in the Latin American Stroke Registry (LASE). Methods: Eighteen centers across Latin American compiled data on demographics, vascular risk factors, clinical stroke description, ancillary tests, and functional outcomes in hospital stay of patients included from January 2012 to January 2017. All these variables were analyzed based on functional outcome at hospital discharge. Results: We included 495 patients with ICH, representing 10.3% of all collected stroke subtypes in LASE. The median in-hospital stay was 9 days (interquartile range, 1-30); 285 (57.6%) were male (median age, 62 years) and 210 female (median age, 65 years). A poor functional outcome (modified Rankin scale, 3-6) was observed in 214 (43.2%) patients, with 62.5% of women (p < 0.009). Mortality was documented in 12.5% of ICH patients. The Kaplan-Meier survival curves presented difference in mortality, with higher frequency in patients > 80 years (HR 1.89,95%C1 1.07-3.35, p = 0.028), with GCS < 8 (HR 0.19, 95%CI 0.11-0.33, p = < 0.001), ventricular irruption (HR 1.88, 95%CI 1.09-3.24, p = 0.0282), and hematoma volume > 30 cc (HR 2.36, 95%C11.17 - 4.77, p = 0.016). Conclusions: Our study demonstrates a poor functional prognosis in 43.2% of ICH patients, with the risk factors for higher mortality being age over 80 years, higher GCS values, and ventricular irruption in the LASE. Our collaborative study contributes substantial insight into the factors influencing ICH occurrence, prognosis, and outcomes in Latin America. [ABSTRACT FROM AUTHOR]

Introduction: Understanding the influence of preexisting cognitive impairment on the poststroke outcome is a critical challenge in the context of current aging and growing population. This study aimed to assess long-term survival of patients with acute ischemic stroke (IS) according to their premorbid cognitive status and to identify contributing factors of death. Methods: Patients with IS were prospectively identified among residents of Dijon, France, using a population-based registry (2013–2017). The association between case fatality at 5 years and prestroke cognitive status was assessed by multivariable Cox models adjusted for other clinical characteristics and preexisting brain damage on the initial CT scan including leukoaraiosis, old vascular brain lesions, and cortical and central brain atrophy, as well as major arterial occlusion. Results: 1,049 patients were included (mean age ± SD: 76.3 ± 15.2 years old, 54% women). Case fatality rates at 5 years were 38.1% in patients without cognitive impairment, 65.9% in patients with prior mild cognitive impairment (MCI, n = 132, 12.6%), and 86.6% in patients with dementia (n = 164, 15.6%) (p < 0.001). MCI (HR = 1.39; 95% CI: 1.06–1.81, p = 0.016) and dementia (HR = 1.89; 95% CI: 1.45–2.46, p < 0.001) were both independently associated with higher case fatality after adjustment for clinical variables. The association remained significant after further adjustment for preexisting brain damage and major arterial occlusion (HR = 1.47; 95% CI: 1.10–1.98, p = 0.009, for MCI and HR = 1.90; 95% CI: 1.43–2.53, p < 0.001, for dementia) among patients with available data on the CT scan (n = 916). Factors associated with death were roughly similar across groups. Conclusion: This study highlighted a poor long-term survival of IS patients with preexisting cognitive impairment, independently of other contributing factors of death. It is critical to better understand the trajectory of IS patients with preexisting cognitive impairment and to identify prognostic markers to guide clinicians in their management strategies.

Objective: The aging world population and increased cardiovascular risk factors contribute to stroke and stroke related morbidity. In this study, we aimed to analyze predictors of increased morbidity of ischemic stroke patients in a single stroke unit. Materials and Methods: Stroke patients recorded in the Istanbul University Stroke Registry between 2014 and 2020 were included and decision tree analyses [chi-squared automatic interaction detection (CHAID) method] were conducted. Gender, diabetes, hypertension, previous stroke, ischemic heart disease, hyperlipidemia, diagnosis of pneumonia during hospitalization in the stroke unit, and atrial fibrillation were determined as possible indicators for poor clinical outcomes. Results: We included 881 patients with ischemic stroke in the study according to the inclusion and exclusion criteria. The mean age of patients was 66.5+-14.4 years and 59% of the patients were male. CHAID analysis revealed that the most important factor for predicting modified Rankin Scale (mRS) score >3 is pneumonia. In patients with mRS score >3 and without pneumonia; hypertension and hyperlipidemia were found to be risk factors for poor functional outcome. Conclusion: Preventative measures in stroke patients should not be limited to secondary prophylaxis of stroke. Avoiding infections in the acute phase plays an essential role in achieving favorable clinical outcomes.

The Japanese National Plan for the Promotion of Measures Against Cerebrovascular and Cardiovascular Diseases was formulated on October 27, 2020. One purpose of this plan was to promote research on cerebrovascular and cardiovascular diseases. Therefore, it is necessary to clarify the actual status of stroke treatment in Japan and operate a national stroke database with high public interest completely and accurately. The Japan Stroke Data Bank (JSDB; https://strokedatabank.ncvc.go.jp/en/) was established by the Ministry of Health, Labor and Welfare Scientific Research in Shimane University (Shimane, Japan) in 1999 and was transferred to the National Cerebral and Cardiovascular Center (Osaka, Japan) as a part of the Cardiovascular Disease Registry in 2015. More than 200,000 of stroke cases have been registered using individual forms from more than 100 nationwide stroke centers over ~20 years. Since there are few large-scale stroke registries with nationwide coverage in Asia, including Japan, compared with those in Europe and North America, the role of the JSDB in the plan will be important in the future. To construct a high-quality stroke registry, we aimed to (1) collect detailed data through individual questionnaires for each participating stroke center, (2) link to external databases (e.g., insurance claims and public death registries), (3) improve the quality of treatment at participating hospitals through benchmarking, and (4) obtain stable funding through sustained support from government and academic societies. We also describe the history of the JSDB and changes in the trend of real-world stroke treatment in Japan based on the results of analysis of data in the JSDB. [ABSTRACT FROM AUTHOR]

Background: The ongoing aging population in high-income countries is responsible for a dramatic rise in the number of elderly stroke patients in whom many questions remain regarding the use of acute revascularization therapy. This review aimed to compare stroke patients from population-based studies to those included in RCTs in terms of age. Summary: Population-based incidence studies conducted in high income that complied with the defined quality criteria were reviewed (period 1985–2020). RCTs of acute ischemic stroke therapy including intravenous thrombolysis (IVT) with either alteplase or tenecteplase and mechanical thrombectomy (MT) were retrieved from systematic reviews performed in recent guidelines from the European Stroke Organisation. When available, information on either mean and/or median age was extracted from each selected article. As a result, 36 population-based registries were included, 34 of which recorded patients with first-ever stroke over 63 distinct time periods with a total of 38,188 patients. Twenty-nine RCTs enrolling 11,666 patients were identified including 13 RCTs related to IVT with alteplase, 11 RCTs about MT, and 5 RCTs on IVT with tenecteplase. A gap in age between stroke patients in the RCTs and those in population-based studies was observed. With few exceptions, mean age of patients in the RCTs was about 4 years younger than in population-based studies, while the median age was approximately 7 years younger. Thirty-five (83%) population-based incidence studies and 8 RCTs (32%) reported a mean age of patients >70 years old. Mean age ≥75 years was observed in 9 (21%) population-based studies and in only 1 (4%) RCT. All population-based studies and half of the RCTs reported a median age >70 years. Key Messages: The gap in age between patients enrolled in acute stroke therapy RCTs and those from population-based studies highlights an under-representation of elderly stroke patients in RCTs. With the current aging of the population, this trend is likely to increase in the coming years, and there is a need to promote the inclusion of older patients, particularly those with disabilities, in future trials to reflect the true population of stroke patients and to help clinicians have evidence-based data to guide their decision-making.

Purpose: Endovascular treatment (ET) in patients with large vessel occlusion stroke (LVOS) with unknown onset or an extended time window can be safe and effective if patients are selected by defined clinical and imaging criteria; however, it is unclear if these criteria should also be applied to patients with unknown onset and unknown time last known well. In this study, we aimed to assess whether absent information on the time patients were last known to be well impacts outcome in patients with unknown onset LVOS. Methods: We analyzed patients who were enrolled in the German Stroke Registry-Endovascular Treatment between 2015 and 2019. Patients with unknown onset and unknown time last known well (LKWu) were compared to patients with known onset (KO) and to patients with unknown onset but known time last known well (LKWk) regarding clinical and imaging baseline characteristics and outcome. Results: Out of 5909 patients, 561 presented with LKWu (9.5%), 1849 with LKWk (31.3%) and 3499 with KO (59.2%). At 90 days, functional independency was less frequent in LKWu (27.0%) compared to KO (42.6%) and LKWk patients (31.8%). These differences were not significant after adjusting for confounders. A main confounder was the initial Alberta stroke program early CT score. Conclusion: The LKWu patients had a similar outcome after ET as KO and LKWk patients after adjusting for confounders. Thus, ET should not be withheld if the time last known well is unknown. Instead, LKWu patients may be selected for ET using the same criteria as in LKWk patients. [ABSTRACT FROM AUTHOR]

Acute spontaneous intracerebral hemorrhage (ICH) is the most severe stroke subtype, with a high risk of death, dependence, and dementia. Knowledge about the clinical profile and early outcomes of ICH patients with lobar versus deep subcortical brain topography remains limited. In this study, we investigated the effects of ICH topography on demographics, cerebrovascular risk factors, clinical characteristics, and early outcomes in a sample of 298 consecutive acute ICH patients (165 with lobar and 133 with subcortical hemorrhagic stroke) available in a single-center-based stroke registry over 24 years. The multiple logistic regression analysis shows that variables independently associated with lobar ICH were early seizures (OR 6.81, CI 95% 1.27–5.15), chronic liver disease (OR 4.55, 95% CI 1.03–20.15), hemianopia (OR 2.55, 95% CI 1.26–5.15), headaches (OR 1.90, 95% CI 1.90, 95% IC 1.06–3.41), alcohol abuse (>80 gr/day) (OR 0–10, 95% CI 0.02–0,53), hypertension (OR 0,41, 95% CI 0.23–0–70), sensory deficit (OR 0.43, 95% CI 0.25–0.75), and limb weakness (OR: 0.47, 95% CI 0.24–0.93). The in-hospital mortality was 26.7% for lobar and 16.5% for subcortical ICH. The study confirmed that the clinical spectrum, prognosis, and early mortality of patients with ICH depend on the site of bleeding, with a more severe early prognosis in lobar intracerebral hemorrhage.

Background: Vertigo is an uncommon symptom among acute stroke victims. Knowledge about the clinical profile, the brain location, and the early outcome in stroke patients with cerebrovascular diseases and vertigo remains limited. Objectives: In this study, the effects of vertigo on cerebral topography and early prognosis in cerebrovascular diseases were investigated. Methods: A comparative analysis in terms of demographics, risk factors, clinical characteristics, stroke subtypes, cerebral and vascular topography, and early outcome was performed between patients with presence or absence of vertigo on a sample of 3743 consecutive acute stroke patients available from a 24-year ongoing single-center hospital-based stroke registry. Results: Vertigo was present in 147 patients (3.9%). Multiple logistic regression analysis showed that variables independently associated with vertigo were: location in the cerebellum (OR 5.59, CI 95% 3.24–9.64), nausea or vomiting (OR 4.48, CI 95% 2.95–6.82), medulla (OR 2.87, CI 95% 1.31–6.30), pons (OR 2.39, CI 95% 1.26–4.51), basilar artery (OR 2.36, CI 95% 1.33–4.17), ataxia (OR 2.33, CI 95% 1.41–3.85), and headache (OR 2.31, CI 95% 1.53–3.49). Conclusion: The study confirmed that the presence of vertigo was not related with increased in-hospital mortality or poor prognosis at hospital discharge. Vertigo is mainly related to non-lacunar vertebrobasilar stroke with topographic localization in the cerebellum and/or brainstem. [ABSTRACT FROM AUTHOR]

Introduction: Ischemic stroke incidence appears to have decreased during the last decades, but most studies focus on the first-ever events and epidemiological data on recurrent stroke are scarce. The aim of our study was to investigate trends in incidence, risk factors, and medication in patients with first-ever and recurrent ischemic stroke between 2010 and 2019 in Sweden. Methods: We included patients (≥18 years old) with ischemic stroke registered in the hospital-based Swedish Stroke Register (Riksstroke) 2010–2019. The coverage of Riksstroke was consistently high (about 90%) during this period. Data were stratified by first-ever and recurrent ischemic stroke in three different time periods (2010–2012, 2013–2016, and 2017–2019) and shown as crude and age-specific incidence rates per 100,000 person-years. Statistics Sweden provided census data on the Swedish population in different age groups. Results: During the study period, 201,316 cases of ischemic stroke were registered in Riksstroke, including 153,865 (76.4%) cases of first-ever ischemic stroke and 46,248 (23.0%) cases of recurrent ischemic stroke (0.6% of cases unclassified). The crude incidence of first-ever ischemic stroke decreased by 17% from 216 (95% CI 214–218) to 179 (95% CI 177–181) between 2010–2012 and 2017–2019, whereas recurrent ischemic stroke decreased by 33% from 72 (95% CI 71–73) to 48 (95% CI 47–49). Between these time periods, diminishing ischemic stroke incidence was seen in all age groups with highest decline noted in those aged 75–84 years (928 [95% CI 914–943] to 698 [95% CI 686–709]; −25% in first-ever ischemic stroke and 361 [95% CI 351–370] to 219 [95% CI 213–226]; −39% in recurrent ischemic stroke) and ≥85 years (1,674 [95% CI 1,645–1,703] to 1,295 [95% CI 1,270–1,320]; −23% in first-ever ischemic stroke and 683 [95% CI 664–702] to 423 [95% CI 409–437]; −38% in recurrent ischemic stroke). Treatment with anticoagulants in patients with atrial fibrillation and lipid-lowering drugs increased considerably in patients with first-ever and recurrent ischemic stroke both at admission and discharge during the study period. Conclusion: Whereas both first-ever and recurrent ischemic stroke rates declined in Sweden between 2010 and 2019, the proportional decline was almost double for recurrent ischemic stroke than for first-ever ischemic stroke and most pronounced in the elderly. Increased use of secondary preventive drugs, in particular anticoagulants in atrial fibrillation, appears to have contributed, but further studies on precise causes for the decline in recurrent ischemic stroke are needed.

Background: Naoshuantong capsules (NC) are commonly used for the treatment of ischemic stroke. Experimental research and small-sample clinical trials have demonstrated that NC is effective in improving neurological recovery. Yet, there is a substantial lack of high-quality evidence on the precision treatment population of NC and long-term safety when making real-world clinical decisions. The acquisition of prospective longitudinal data in the real-world setting is essential to fully characterize the effectiveness and safety profile of NC for patients with ischemic stroke. Methods: The Vital real-world Experience regarding Naoshuantong capsules for Unselected ischemic Stroke (VENUS) registry is a prospective, multicenter, observational study aiming to register 5,000 patients. Eligible adult patients diagnosed with ischemic stroke and newly treated with NC within 30 days of symptom onset will be consecutively registered from 84 participating sites across the Chinese mainland. Baseline data will be recorded at the patient registry, and all patients will be regularly followed up at 2, 4, 8, and 12 weeks after the initial patient registry, and 180 days after ischemic stroke onset. The primary outcome is the distribution of scores on the modified Rankin Scale at 12 weeks after initial patient registry. Adverse events will be recorded during the study for NC safety assessment. Results: A total of 4,185 patients with ischemic stroke were enrolled, among which 37.06% patients were female. The average age of all patients was 65.22 years. The proportion of patients whose course of ischemic stroke was less than 14 days accounted for 93.45%. Conclusion: The VENUS registry is designed to comprehensively document medical data regarding NC treatment for ischemic stroke in real-world settings. The findings of this study will provide valuable insights into the clinical management of patients with ischemic stroke and the subsequent outcomes of the use of NC when included in the best clinical practice.

In patients with mRS score >3 and without pneumonia; hypertension and hyperlipidemia were found to be risk factors for poor functional outcome. Conclusion: Preventative measures in stroke patients should not be limited to secondary prophylaxis of stroke. Avoiding infections in the acute phase plays an essential role in achieving favorable clinical outcomes. [ABSTRACT FROM AUTHOR]

Objectives: In Japan, many hospitals have joined the diagnosis procedure combination/per-diem payment system (DPC/PDPS), which provides unified information about inpatients. DPC data are digitized, and the number of participating hospitals has increased recently. Herein, we evaluated the potential of a stroke registry constructed using these unified DPC data from all hospitals in the Iwate Prefecture, Japan. Methods: The proportion of cerebrovascular disease (CVD) cases registered by DPC-participating hospitals was calculated and compared with all registered cases in the Iwate Stroke Registry in 2008–2017. The cases were categorized based on sex, age-groups, stroke subtypes, and first-ever onset or recurrence onset. Based on the registered cases in the stroke registry, the accuracy of the CVD cases extracted by the disease name from DPC data of a typical core hospital and a typical noncore hospital was evaluated. Results: Of the 71 hospitals with 9,992 beds in the Iwate Prefecture in 2018, 50 hospitals with 8,316 beds participated in the DPC system. The proportion of registered cases from participating hospitals was 95.2% (44,779/47,018) for all stroke types (95.6% men and 94.9% women), 94.3% for cerebral infarction, 97.0% for intracerebral hemorrhage, and 98.7% for subarachnoid hemorrhage, whereas it was 95.7% for first-ever onset and 94.1% for recurrent onset. The proportion of registered cases decreased with increasing patient age. Attending doctors and researchers registered 486 and 41 CVD cases from the core and noncore hospitals, respectively, whereas 455 and 46 CVD cases were extracted from the DPC data of these hospitals, respectively. This yielded 86.6% sensitivity, 99.3% specificity, 92.5% positive predictive value, and 98.7% negative predictive value for the core hospital; these values were 92.7%, 98.6%, 82.6%, and 99.5%, respectively, for the noncore hospital. Discussion/Conclusions: The stroke registry constructed using DPC data from all hospitals of Iwate Prefecture appears to be adequately complete and accurate. [ABSTRACT FROM AUTHOR]

Background: The most recent time trends on intravenous thrombolysis (IVT) utilization for acute ischemic stroke was reported in 2011 using the Get with the Guidelines. Our objectives are to assess and validate the change in IVT utilization through 2014 in a national sample of Medicare beneficiaries and to examine the effect of patient, stroke center designation, and geography on IVT utilization. Methods: We built a comprehensive national stroke registry by combining patient-level, stroke center status, and geographical characteristics, using multiple data sources. Using multiple national administrative databases from 2007 to 2014, we generated a mixed-effect logistic regression model to characterize the independent associations of patient, hospital, and geographical characteristics with IVT in 2014. Results: Use of IVT increased consistently from 2.8% in 2007 to 7.7% in 2014, P < 0.001. Between group differences persisted, with lower odds of use in patients who were ≥86 years (aOR 0.74, 95% CI 0.65–0.83), Black (aOR 0.73, 95% CI 0.61–0.87), or treated at a rural hospital (aOR 0.88, 95% CI 0.77–1.00). Higher odds of use were observed in patients who arrived by ambulance (aOR 2.67, 95% CI 2.38–3.00), were treated at a hospital certified as a stroke center (aOR 1.96, 95% CI 1.68–2.29), or were treated at hospitals located in the most socioeconomically advantaged areas (aOR 1.27, 95% CI 1.05–1.54). Conclusions: Between 2007 and 2014, the frequency of IVT for patients with acute ischemic stroke increased substantially, though differences persisted in the form of less frequent treatment associated with certain characteristics. These findings can inform ongoing efforts to optimize the delivery of IVT to all AIS patients nationwide. [ABSTRACT FROM AUTHOR]

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has led to changes in stroke patients' healthcare use. This study evaluated changes in Korean stroke patients' health-seeking behaviors and stroke care services using data from the Korean Stroke Registry (KSR). Methods: We reviewed data from patients with acute stroke and transient ischemic attack (TIA) during 2019 (before COVID-19 period) and 2020 (COVID-19 period). Outcomes included patient characteristics, time from stroke onset to hospital arrival, and in-hospital stroke pathways. Subgroup analyses were performed for an epidemic region (Daegu city and Gyeongsangbuk-do region, the D-G region). Results: The study included 1,792 patients from the pre-COVID-19 period and 1,555 patients from the COVID-19 period who visited hospitals that contribute to the KSR. During the COVID-19 period, the D-G region had two-thirds the number of cases (vs. the pre-CO-VID-19 period) and a significant decrease in the proportion of patients with TIA (9.97%–2.91%). Unlike other regions, the median onset-to-door time increased significantly in the D-G region (361 min vs. 526.5 min, p = 0.016), and longer onset-to-door times were common for patients with mild symptoms and who were in their 60s or 70s. The number of patients who underwent intravenous thrombolysis also decreased during the COVID-19 period, although the treatment times were not significantly different between the 2 periods. Discussion/Conclusion: Korean stroke patients in a CO-VID-19 epidemic region exhibited distinct changes in health-seeking behaviors. Appropriate triage system and public education regarding the importance of early treatment are needed during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

The aim of the present study was to investigate whether selection bias occurred by comparing baseline characteristics from participants with non-participants in Nor-COAST.Patients and Methods: Nor-COAST is a prospective cohort multi-center study, recruiting participants from five Norwegian hospitals. Patients with the diagnosis of acute stroke were screened for inclusion. Baseline data from the participants recruited between May 2015 and March 2017 were compared to corresponding data from those not participating in Nor-COAST but registered in the Norwegian Stroke Registry. Regression analysis was used to assess whether age, stroke severity, sex and stroke subtype were independently associated with inclusion in the study.Results: Out of 2505 available patients, 815 (32.5%) were included in Nor-COAST. There were no differences between participants and non-participants with respect to age (mean (SD) age 73.5 (11.7) versus 74.2 (14.5) years) or sex (44.8% versus 46.9% women). A significantly larger proportion of the participants were independent prior to stroke (87% versus 78%), had mild strokes (69% versus 55%) and suffered from cerebral infarction (90% versus 84%). The regression analysis showed decreased odds ratio (OR) of being included for those with higher degree of pre-stroke dependency (OR 0.895, 95% CI 0.825 to 0.971, p=0.007) and a more severe stroke (OR 0.952, 95% CI 0.939 to 0.966, p< 0.001).Conclusion: The participants in Nor-COAST had a better pre-stroke health condition and milder strokes compared to non-participants. However, the participants should be regarded as representative of the majority of the stroke population which suffers from mild strokes. Nevertheless, baseline information for non-participants should be available also in future clinical studies to make it easier to identify which part of the stroke population the results can be generalized to.Keywords: neurocognitive disorder, dementia, cerebrovascular disease, stroke registry

Introduction: This article summarizes the medical experience in establishing stroke units and systemic thrombolysis in Georgia, which, like many other post-Soviet countries, still faces problems in organizing stroke care even after 30 years of independence. Patients and Methods: We created an example of treating acute stroke with systemic thrombolysis and introduced stroke units in several hospitals in the country, including standardization of the diagnostic and treatment process, consistent evaluation, and monthly feedback to the stroke unit staff. Results: Systemic thrombolysis has become a clinical routine in some large hospitals and is meanwhile reimbursed by the state insurance. The data of consecutive 1,707 stroke patients in 4 major cities demonstrated significant time lost at the prehospital level, due to failure in identifying stroke symptoms, delay in notification, or transportation. The consequent quality reports resulted in a dramatic increase in adherence to the European and national guidelines. A mandatory dysphagia screening and subsequent treatment led to a decrease in pneumonia rates. Discussion: We discuss our experience and suggestions on how to overcome clinical, financial, and ethical problems in establishing a stroke services in a developing country. Conclusion: The Georgian example might be useful for doctors in other post-Soviet countries or other parts of the world. [ABSTRACT FROM AUTHOR]

Background: Given the complexity of stroke treatment and the current widespread use of traditional Chinese medicine (TCM) in the absence of robust, large, long-term effectiveness and safety studies, and the lack of nationwide epidemiology and clinical characteristics of patients with stroke receiving TCM treatment, the acquisition of data from longitudinal cohorts is essential. We intend to generate the major clinical characteristics of patients with stroke who receive TCM treatment and to investigate the effectiveness and safety of TCM in the Chinese population.Methods: The China Stroke Registry for Patients with Traditional Chinese Medicine (CASES-TCM) study is a prospective, multicenter, observational disease registry aiming to register 20,000 hospitalized patients. Eligible adult patients with clearly diagnosed acute ischemic stroke or intracerebral hemorrhage within 7 days of symptom onset will be consecutively registered from 126 participating sites across China. Baseline data will be recorded, and all patients will be regularly followed up at 3, 6, 12, and 24 months after stroke onset. Collected data will be entered into a web-based system with high-level data security. The primary outcomes include the distribution of scores on the modified Rankin Scale at the 3-months follow-up, and recurrent stroke events within the 12-months follow-up.Conclusion: To our knowledge, the CASES-TCM study is the first and largest nationwide registry to document comprehensive data on TCM treatment in patients with acute stroke. The findings of this study will be valuable to improve our knowledge about TCM treatment for patients with stroke and its subsequent outcomes in the actual clinical setting, consequently facilitating and standardizing the optimization of individualized interventions with TCM for stroke prevention and treatment in China.Study registration: This study was registered with Clinicaltrials.gov (URL: https://clinicaltrials.gov/, Unique identifier: NCT04921397).

Background and Purpose: The role of community health workers (CHWs) in stroke surveillance and in establishing the stroke care pathway has not been studied. The aim of the study was to evaluate the feasibility of using CHWs in the public health system to identify stroke patients for population-based stroke registration and to study the establishment of acute stroke care pathway in rural areas of Ludhiana, Punjab, Northwest India. Methods: Two rural blocks in Ludhiana district, comprising 164 villages and a population of 259,778, were selected. Phase-1 (feasibility study) was from August to November 2016 and phase-2 from December 2016 to November 2018. All first-ever stroke cases in adults (aged ≥18 years) were included. The accredited social health activists (ASHAs) were trained to identify stroke patients in the community, who were later evaluated by a neurologist. Stroke characteristics were recorded, and the outcome was assessed at 6 months using modified Rankin scale (0–2, good outcome). Findings: During phase-2, 359 first-ever stroke patients and 102 stroke mimics were identified. The age-standardized incidence rate was 218.5/100,000 and 197∙6/100,000 for each year. Half (52.4%) of the patients reached health-care facilities within 4.5 h, yet none of them received thrombolysis. Very few patients (1.9%) utilized free government 108 ambulance service to reach a health-care facility. Out of 359 stroke cases, the majority (306, 85.23%) were reported by ASHAs and 14.77% were reported by other sources. Brain imaging was available in 127 (35.4%) patients, and 100 (78.7%) had ischemic stroke. The most common risk factor was hypertension (320, 89%) and drug abuse (154, 42.9%). At 6 months, 168 (64%) patients had a good outcome. Conclusion: ASHAs were able to identify stroke patients in the villages. Despite high numbers of patients reaching health-care facilities within a window period, the hospitals were unable to provide acute stroke treatment like thrombolysis. The health-care system needs to be strengthened to improve stroke care. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Clinical trials have historically underrepresented patients with posterior circulation ischemic stroke (PCIS). This study aimed to comprehensively assess the clinical characteristics and outcomes of PCIS patients compared to those with anterior circulation ischemic stroke (ACIS). A retrospective analysis was conducted using data from the Japan Stroke Data Bank, encompassing 20 years across 130 stroke centers. The study focused on patients diagnosed with PCIS or ACIS. Among 37,069 patients reviewed, 7425 had PCIS, whereas 29,644 had ACIS. PCIS patients were younger and had a lower female representation than ACIS patients. Notably, PCIS patients had more favorable outcomes: 71% achieved a modified Rankin Scale of 0–2 or showed no deterioration at discharge (17 days at the median after admission), compared to 60% for ACIS patients (p < 0.001). Factors associated with an unfavorable outcome in the PCIS subgroup were older age, female sex (assigned at birth), history of hypertension, and higher National Institute of Health Stroke Scale (NIHSS) scores at admission. In both sexes, older age and higher NIHSS scores were negatively associated with favorable outcomes. PCIS patients demonstrated a more favorable prognosis than ACIS patients. Factors like older age, female sex, and higher NIHSS scores at admission were identified as independent predictors of unfavorable outcomes in PCIS patients. Older age and higher NIHSS scores at admission were common independent negative factors for a favorable outcome regardless of sex. • PCIS underrepresented in clinical trials historically. • Analyzed PCIS outcomes in a 20-year nation wide registry. • PCIS had better outcomes than ACIS. • Older age, female sex, and high NIHSS predict poor PCIS outcomes..

Prediction of outcome after stroke may help clinicians provide effective management and plan long-term care. We aimed to develop and validate a score for predicting good functional outcome available for hospitals after ischemic stroke using linked data. A total of 22,005 patients with acute ischemic stroke from the Clinical Research Center for Stroke Registry between July 2007 and December 2014 were included in the derivation group. We assessed functional outcomes using a modified Rankin scale (mRS) score at 3 months after ischemic stroke. We identified predictors related to good 3-month outcome (mRS score ≤ 2) and developed a score. External validations (geographic and temporal validations) of the developed model were performed. The prediction model performance was assessed using the area under the receiver operating characteristic curve (AUC) and the calibration test. Stroke severity, sex, stroke mechanism, age, pre-stroke mRS, and thrombolysis/thrombectomy treatment were identified as predictors for 3-month good functional outcomes in the S-SMART score (total 34 points). Patients with higher S-SMART scores had an increased likelihood of a good outcome. The AUC of the prediction score was 0.805 (0.798–0.811) in the derivation group and 0.812 (0.795–0.830) in the geographic validation group for good functional outcome. The AUC of the model was 0.812 (0.771–0.854) for the temporal validation group. Moreover, they had good calibration. The S-SMART score is a valid and useful tool to predict good functional outcome following ischemic stroke. This prediction model may assist in the estimation of outcomes to determine care plans after stroke. [ABSTRACT FROM AUTHOR]

Background Reports on sex differences in stroke outcome and risk factors are scarce in Latin America. Our objective was to analyze clinical and prognostic differences according to sex among participants in the LASE (Latin American Stroke Registry). Methods and Results Nineteen centers across Central and South America compiled data on demographics, vascular risk factors, clinical stroke description, ancillary tests, and functional outcomes at short‐term follow‐up of patients included from January 2012 to January 2017. For the present study, all these variables were analyzed according to sex at hospital discharge. We included 4788 patients with a median in‐hospital stay of 8 days (interquartile range, 5–8); 2677 were male (median age, 66 years) and 2111 female (median age, 60 years). Ischemic stroke occurred in 4293: 3686 as cerebral infarction (77%) and 607 as transient ischemic attack cases (12.7%); 495 patients (10.3%) corresponded to intracerebral hemorrhage. Poor functional outcome (modified Rankin scale, 3–6) was present in 1662 (34.7%) patients and 38.2% of women (P

Objective: The aim of this study was to assess long-term survival after stroke and to compare survival profiles of patients according to stroke subtypes, age, and sex, using relative survival (RS) method. Methods: All patients with a first-ever stroke were prospectively recorded in the population-based Dijon Stroke Registry from 1987 to 2016. RS is the survival that would be observed if stroke was the only cause of death. Ten-year RS was estimated using a flexible parametric model of the cumulative excess mortality rate, which was obtained by matching the observed all-cause mortality in the stroke cohort to the expected mortality in the general population. A separate model was fitted for each stroke subtypes, first fitted for each age and sex separately, and then adjusted for age and sex. Results: In total, 5,259 patients (mean age 74.9 ± 14.3 years, 53% women) were recorded including 4,469 ischemic strokes (IS), 655 intracerebral hemorrhages (ICH), and 135 undetermined strokes. In IS patients, unadjusted RS was 82% at 1 year and decreased to 62% at 10 years. Adjusted RS showed a lower survival in older age groups (p < 0.001), but no difference between men and women (p = 0.119). In ICH patients, unadjusted RS was 56 and 42% at 1 and 10 years, respectively, with a lower adjusted survival in older age groups (p < 0.001), but no sex differences (p = 0.184). Conclusion: This study showed that RS after stroke is lower in older than in younger patients but without significant sex differences, and survival profiles differ according to stroke subtypes. Since RS allows a better estimation of stroke-related death than observed survival does, especially in old patients, such a method is adapted to provide reliable information when considering long-term outcome.

Background: Lifestyle changes and evolving healthcare practices in Korea have influenced disease patterns and medical care. Since strokes have high disease burden in countries with aging populations, it is necessary to evaluate the associated recent disease characteristics and patient care patterns. The Korean Stroke Registry is a nationwide, multicenter, prospective, hospital-based stroke registry in Korea used to monitor these changes across the population. Aims: We aimed to evaluate the recent status of clinical characteristics and management of stroke cases in order to identify changes in the Korean population across time. Methods: This study used Korean Stroke Registry data from patients experiencing ischemic stroke or transient ischemic attack patients, between 2014 and 2018. We analyzed data on demographics, risk factors, stroke subtypes, and treatments that included thrombolysis. Results: A total of 39,291 patients (mean age 68.0 ± 13.0, 58.3% male) were analyzed. The proportions of hypertension, diabetes mellitus, dyslipidemia, atrial fibrillation, and prior stroke were 63.4%, 30.9%, 27.7%, 19.4%, and 17.1%, respectively. In the stroke subtype analysis, the frequency of large artery atherosclerosis was highest (32.6%), followed by cardioembolism (21.3%) and small vessel occlusion (19.9%). Acute reperfusion therapy was conducted in 15.3% of cases (11.7% using intravenous tPA and 7.3% using intra-arterial thrombectomy). Intra-arterial thrombectomy also demonstrated a steep increasing trend over time (RR 1.095 (1.060–1.131), p < 0.001). Conclusions: This study provided analysis of nationwide, hospital-based, quality-controlled data from the Korean Stroke Registry database regarding changes in the characteristics, risk factors, and treatments of strokes in Korea.

Background: Stroke population-based studies in the same setting comparing time trends of rates are a gold standard method to determine the primary prevention status of stroke. Twelve years ago, we measured the stroke incidence and mortality in Matão city, Southeast of Brazil. Objective: This second Matão stroke registry study aimed to determine the time trends in the incidence, mortality, case fatality, and functional status of patients with stroke. Methods: This was a prospective, population-based study known as the Matão Preventing Stroke (MAPS). We determined all incident stroke events that occurred between August 1, 2015, and July 31, 2016. Between the periods of November 1, 2003, to October 31, 2004, and August 1, 2015, to July 31, 2016, the rates were age adjusted to the Brazilian and world population. Functional status was measured by Barthel scale 1 year after the index event. Results: We registered 81 cases of incident stroke. Demographic and cardiovascular risk factors were similar in both periods. The mean age increased by 9%, from 65.2 (95% CI 62.6–67.8) to 71.0 (95% CI 68.1–73.8) years. Between 2003–2004 and 2015–2016, the age-adjusted incidence decreased by 39% (incidence rate ratio [IRR] 0.61; 95% CI 0.46–0.79) and mortality by 50% (IRR 0.50; 95% CI 0.31–0.94). The 1-year case fatality was 26%; approximately 56% of the patients were functionally independent, while 7% had a recurrent stroke. Compared with the results of our first registry study, these outcomes did not differ significantly. Conclusion: Our findings agree with those of previous studies, showing a decline in the incidence and mortality of stroke in Brazil. Improvements in local public health care might explain these declines. [ABSTRACT FROM AUTHOR]

Abstract Background Many studies have determined that dehydration is an independent predictor of outcome after ischemic stroke (IS); however, none have determined if the use of thrombolytic therapy modifies the negative impact of poor hydration. To inform the stroke registry established at our institution, we conducted a retrospective study to determine if dehydration remains a negative prognostic factor after IS patients treated with tissue plasminogen activator (tPA). Methods Between 2007 and 2012, we recruited 382 subjects; 346 had data available and were divided into 2 groups on the basis of their blood urea nitrogen/creatinine (BUN/Cr) ratio. Dehydrated subjects had a BUN/Cr ratio ≥ 15; hydrated subjects had a BUN/Cr

Clinical outcomes of unknown onset stroke (UOS) are influenced by the enlargement of the therapeutic time window for reperfusion therapy. This study aimed to investigate and describe the characteristics and clinical outcomes of patients with UOS. Patients with acute ischemic stroke (AIS) who were admitted within 24 h of their last known well time, from January 2017 to December 2020, were included. Data were obtained from a long-lasting nationwide hospital-based multicenter prospective registry: the Japan Stroke Data Bank. The co-primary outcomes were the National Institutes of Stroke Scale (NIHSS) scores on admission and unfavorable outcomes at discharge, corresponding to modified Rankin Scale (mRS) scores of 3–6. Overall, 26,976 patients with AIS were investigated. Patients with UOS (N = 5783, 78 ± 12 years of age) were older than patients with known onset stroke (KOS) (N = 21,193, 75 ± 13 years of age). Age, female sex, higher premorbid mRS scores, atrial fibrillation, and congestive heart failure were associated with UOS in multivariate analysis. UOS was associated with higher NIHSS scores (median = 8 [interquartile range [IQR]: 3–19] vs. 4 [1–10], adjusted incidence rate ratio = 1.37 [95% CI: 1.35–1.38]) and unfavorable outcomes (52.1 vs. 33.6%, adjusted odds ratio = 1.27 [1.14–1.40]). Intergroup differences in unfavorable outcomes were attenuated among females (1.12 [0.95–1.32] vs. males 1.38 [1.21–1.56], P = 0.040) and in the subgroup that received reperfusion therapy (1.10 [0.92–1.33] vs. those who did not receive therapy 1.23 [1.08–1.39], P = 0.012). UOS was associated with unfavorable outcomes but to a lesser degree among females and patients receiving reperfusion therapy. [Display omitted] • Unknown onset stroke (UOS) accounted for 21.4% of acute ischemic stroke cases. • UOS was independently associated with unfavorable outcomes. • This association was attenuated in females and reperfusion therapy receivers.

Background and purposeStroke has been scarcely studied in Latin America (LA). The Mexican Institute of Neurology Stroke Registry was established in 1990 as a prospective computer-based database to register data obtained from patients admitted with stroke. Using this data, we attempted to define the profile of risk factors and outcomes.MethodsThe demographic data, stroke description, ancillary tests, vascular risk factors, and modified Rankin scale (mRs) were registered. Ischemic stroke subtyping was based on the Trial of Org 10,172 of the Acute Stroke Treatment classification. We followed-up patients using multiple overlapping methods. Primary outcomes included mRs, recurrence, and death at 30 days and at the end of follow-up.ResultsWe included 4,481 patients with a median follow-up of 27 months, (17,281 person-years follow-up). The mean age was 52.8 ± 18 years. There were 2,229 males (50%) included in the study. CI was present in 64.9%, intracerebral hemorrhage (ICH) in 25.6%, and cerebral venous thrombosis (CVT) in 6.3%. Hypertension was the major risk factor (46.5%). The most common cause of CI was atherosclerosis (27%). ICH was mainly hypertensive (58%), and 60% of CVT were puerperal. Overall, the mortality rate was 24.5%. The recurrence rate was 16.9%. Poor outcome (mRs ≥ 3) was found in 56.2% of patients. The best outcomes were observed in CVT patients (74.5% mRs ≤ 2), whereas 72.1% ICH patients had mRs ≥3.ConclusionThis is one of the largest hospital-based registries in LA and shows significant differences with other previously published registries, including a younger age, relatively less hypertension, and larger proportion of CVT. Poor functional outcome was common. This study adds to the understanding of geographic differences in stroke characteristics and outcomes.

Characteristics of stroke cases, acute stroke care, and outcomes after stroke differ according to geographical and cultural background. To provide epidemiological and clinical data on stroke care in South Korea, we analyzed a prospective multicenter clinical stroke registry, the Clinical Research Center for Stroke-Fifth Division (CRCS-5). Patients were 58% male with a mean age of 67.2±12.9 years and median National Institutes of Health Stroke Scale score of 3 [1-8] points. Over the 6 years of operation, temporal trends were documented including increasing utilization of recanalization treatment with shorter onset-to-arrival delay and decremental length of stay. Acute recanalization treatment was performed in 12.7% of cases with endovascular treatment utilized in 36%, but the proportion of endovascular recanalization varied across centers. Door-to-IV alteplase delay had a median of 45 [33-68] min. The rate of symptomatic hemorrhagic transformation (HT) was 7%, and that of any HT was 27% among recanalization-treated cases. Early neurological deterioration occurred in 15% of cases and were associated with longer length of stay and poorer 3-month outcomes. The proportion of mRS scores of 0-1 was 42% on discharge, 50% at 3 months, and 55% at 1 year after the index stroke. Recurrent stroke up to 1 year occurred in 4.5% of patients; the rate was higher among older individuals and those with neurologically severe deficits. The above findings will be compared with other Asian and US registry data in this article.

The Stroke Advisory Council and its partners created the NC Stroke System of Care, an online repository of strategies and resources, in efforts to prevent rising rates of stroke in our state and to steer our work. A stroke registry was developed to gain a more comprehensive view of stroke in the state and identify gaps in care and health inequities., Competing Interests: Acknowledgments: The author is the executive director of the Justus-Warren Heart Disease and Stroke Prevention Task Force, and reports no further con­flicts of interest., (Copyright ©2024 by the North Carolina Institute of Medicine and The Duke Endowment.

Background: Limited data on stroke exist for Costa Rica. Therefore, we created a stroke registry out of patients with stroke seen in the Acute Stroke Unit of the Hospital Calderon Guardia.Methods: We analyzed 1319 patients enrolled over a 7-year period, which incorporated demographic, clinical, laboratory, and neuroimaging data.Results: The mean age of patients with stroke was 68.0 ± 15.5 years. Seven hundred twenty-five were men and the age range was 13-104 years. The most prevalent risk factors were hypertension (78.8%), dyslipidemia (36.3%), and diabetes (31.9%). Fifteen percent had atrial fibrillation and 24.7% had a previous stroke or transient ischemic attack. Prevalence of hypertension and atrial fibrillation increased with age; however, younger patients were more associated with thrombophilia. We documented 962 (72.9%) ischemic and 270 (20.5%) hemorrhagic strokes. Of the ischemic strokes, 174 (18.1%) were considered secondary to large-artery atherothrombosis, 175 (18.2%) were due to cardiac embolism, 19 (2.0%) were due to lacunar infarcts, and 25 (2.6%) were due to other determined causes. Five hundred sixty-nine (59.1%) remained undetermined. Atherothrombotic strokes were mostly associated with dyslipidemia, diabetes, metabolic syndrome, and obesity, whereas lacunar infarcts were associated with hypertension, smoking, sedentary lifestyle, and previous stroke or transient ischemic attack. Of our patients, 69.9% scored between 0 and 9 in the initial National Institutes of Health Stroke Scale (NIHSS).Conclusions: We found differences in sociodemographic features, risk factors, and stroke severity among stroke subtypes. Risk factor prevalence was similar to other registries involving Hispanic populations. [ABSTRACT FROM AUTHOR]

BackgroundPulse pressure (PP) is related to cardiac function, arterial stiffness, fluid status, and vascular events. This study aimed to explore the prognostic role of PP upon admission in patients with acute ischemic stroke (AIS) based on a nation‐wide stroke registry. Methods and ResultsWe evaluated the association between PP upon admission and outcomes 3 months after a stroke in patients who had an AIS registered in the Taiwan Stroke Registry, including 56 academic and community hospitals between 2006 and 2013. Three months after the stroke, unfavorable outcomes were defined using a modified Rankin scale of 3 to 6. Of 33 530 patients (female, 40.6%; mean age, 68.8±13.3 years) who had an AIS, PP upon admission had a reverse J‐curve association with an unfavorable outcome. After adjusting for clinical variables, including AIS subtypes, initial National Institutes of Health Stroke Scale, and systolic and diastolic blood pressure upon admission, a PP of

BackgroundNationwide data on the clinical profile and outcomes of ischemic stroke in younger adults are still scarce. Our aim was to analyze clinical characteristics and outcomes of young patients with first-ever ischemic stroke compared to older patients.MethodsThe National Acute Stroke ISraeli registry is a nationwide prospective hospital-based study performed triennially. Younger adults, aged 50 years and younger, were compared with patients, aged 51–84 years regarding risk factors, clinical presentation, stroke severity, stroke etiology, and outcomes. A logistic model for stroke outcome was fitted for each age group.Results336 first-ever ischemic strokes were identified among patients aged 50 years and younger and 3,243 among patients 51–84 years. Younger adults had lower rates of traditional vascular risk factors, but 82.7% had at least one of these risk factors. Younger adults were more likely to be male (62.8%), current smokers (47.3%), and to have a family history of stroke (7.4%). They tended to have less common stroke presentation such as sensory disturbances or headache and were more likely to arrive at the hospital independently by car. The majority of young adults (70%) had a favorable outcome (modified Ranking Scale; mRS ≤ 1) at discharge, but 11.7% had poor outcome (mRS > 3) and 18.2% had an in-hospital complication.

Conclusion: Our findings, in this nationwide registry, demonstrate the relatively high rate of smoking and family history of stroke, and the lower rate of hospital arrival by ambulance among young adults. This calls for increasing awareness to the possibility of stroke among young adults and for better prevention, especially smoking cessation. [ABSTRACT FROM AUTHOR]
