RESUMO
BACKGROUND: There is a well-known association between low socioeconomic status (SES), poor survival, and clinician-reported outcomes after stroke. We aimed to assess socioeconomic differences in Patient Reported Outcome Measures 3 months after stroke. METHODS: This nationwide cohort study included patients registered with acute stroke in the Swedish Stroke Register 2015-2017. Patient Reported Outcome Measures included activities of daily living (mobility, toileting, and dressing), and poststroke symptoms (low mood, fatigue, pain, and poor general health). Information on SES prestroke was retrieved from Statistics Sweden and defined by a composite measure based on education and income tertiles. Associations between SES and Patient Reported Outcome Measures were analyzed using logistic regression adjusting for confounders (sex and age) and additionally for potential mediators (stroke type, severity, cardiovascular disease risk factors, and living alone). Subgroup analyses were performed for stroke type, men and women, and younger and older patients. RESULTS: The study included 44â 511 patients. Of these, 31.1% required assistance with mobility, 18% with toileting, and 22.2% with dressing 3 months after stroke. For poststroke symptoms, 12.3% reported low mood, 39.1% fatigue, and 22.7% pain often/constantly, while 21.4% rated their general health as poor/very poor. Adjusted for confounders, the odds of needing assistance with activities of daily living were highest for patients with low income and primary school education, for example, for mobility, odds ratio was 2.06 (95% CI, 1.89-2.24) compared with patients with high income and university education. For poststroke symptoms, odds of poor outcome were highest for patients with low income and university education (eg, odds ratio, 1.79 [95% CI, 1.49-2.15] for low mood). Adjustments for potential mediators attenuated but did not remove associations. The associations were similar in ischemic and hemorrhagic strokes and more pronounced in men and patients <65 years old. CONCLUSIONS: There are substantial SES-related differences in Patient Reported Outcome Measures poststroke. The more severe outcome associated with low SES is more pronounced in men and in patients of working age.

OBJECTIVES: The primary objective of this study was to examine the impact of the COVID-19 pandemic on the quality of stroke care for patients with preexisting dementia, compared with patients who had only stroke. The secondary aim was to investigate how the quality of stroke care changed during the pandemic and post-pandemic periods compared with the pre-pandemic period in patients with preexisting dementia. DESIGN: A registry-based, nationwide cohort study in Sweden. SETTING AND PARTICIPANTS: We included patients with a first stroke between 2019 and 2022, both with and without dementia. The study periods were defined as follows: pre-pandemic (January 1, 2019, to February 29, 2020), COVID-19 pandemic (March 1, 2020, to February 24, 2022), and post-COVID-19 pandemic period (February 25, 2022, to September 19, 2022). The outcomes examined were the following quality indicators of stroke care, suggested by the national guideline of stroke care in Sweden: stroke admission site, performance of swallowing assessment, reperfusion treatment, assessment for rehabilitation, and early supported discharge. METHODS: The associations were studied through group comparisons and binary logistic regressions. RESULTS: Of the 21,795 patients with strokes, 1357 had documented preexisting dementia, and 20,438 had stroke without a dementia diagnosis. Throughout all study periods, a significantly lower proportion of patients with stroke with preexisting dementia, compared with stroke-only patients, received reperfusion treatment, assessments for rehabilitation, and early supported discharge from stroke units. In the subgroup of stroke patients with preexisting dementia, no significant associations were found regarding the quality indicators of stroke care before, during, and after the pandemic. CONCLUSIONS AND IMPLICATIONS: Disparities in quality of stroke care were observed between stroke patients with preexisting dementia and those with only stroke during the COVID-19 pandemic. However, there were no statistically significant differences in stroke care for patients with dementia across the pandemic.

BACKGROUND: A rapid shift has occurred from vitamin K antagonists toward direct oral anticoagulants, which have a lower risk of intracerebral hemorrhage (ICH). However, effects on clinical outcomes after ICH are understudied. We aimed to describe the prevalence of antithrombotic drugs and to study the prognosis among prestroke functionally independent Swedish patients with ICH. METHODS AND RESULTS: We identified all patients diagnosed with nontraumatic ICH in 2017 to 2021 from the Swedish Stroke Register (n=13 155) and assessed death and functional outcome at 3 months after ICH in prestroke functionally independent patients (n=10 014). Functional outcome was estimated among 3-month survivors on the basis of self-reported activities of daily living scores. Risks of outcomes were estimated using Poisson regression. In 13 155 patients, 14.5% used direct oral anticoagulant, 10.1% vitamin K antagonists, and 21.6% antiplatelets at ICH onset. Among 10 014 pre-stroke activities of daily living-independent patients, oral anticoagulants and antiplatelets were associated with increased mortality risk (adjusted risk ratio, 1.27 [95% CI, 1.13-1.43]; P<0.001; and adjusted risk ratio, 1.23 [95% CI, 1.13-1.34]; P<0.001 respectively). Mortality risk did not statistically differ between antiplatelets and oral anticoagulants nor between direct oral anticoagulant and vitamin K antagonists. Among 5126 patients with nonmissing functional outcome (69.1% of survivors), antiplatelets (adjusted risk ratio, 1.06 [95% CI, 0.99-1.13]; P=0.100) and oral anticoagulants (adjusted risk ratio, 1.01 [95% CI, 0.92-1.12]; P=0.768) were not statistically significantly associated with functional dependence. CONCLUSIONS: There was no statistically significant difference in mortality risk between direct oral anticoagulant and vitamin K antagonists in prestroke functionally independent patients (unadjusted for oral anticoagulant class indication). Furthermore, mortality risk in antiplatelet and oral anticoagulant users might differ less than previously suggested.

BACKGROUND: Due to the rapid growth of the world´s oldest population, the number of older persons with stroke is expected to rise. Knowledge of stroke etiology is essential to offer personalized and equal health care across age groups. The present systematic review aimed to investigate the prevalence of etiological subtypes of ischemic and hemorrhagic stroke in older compared to younger people. METHODS: MEDLINE, Embase, Cochrane, Epistemonikos, and Cinahl were systematically searched for studies regarding etiological classification in people ≥80 years compared to those <80 years with ischemic or hemorrhagic stroke. RESULTS: Out of 28 441 identified articles, eight met the inclusion criteria. In total, 8223 individuals were included in meta-analyses, of whom 2997 were 80 years or older. We demonstrated a higher prevalence of cardioembolic stroke in people ≥80 years OR 1.68 (95% CI, 1.12-2.53). Small vessel disease was significantly less common in older people OR .64 (95% CI, .50-.81). Regarding large vessel disease, no statistically significant difference between the two groups was shown OR 1.05 (95% CI, .77-1.43). CONCLUSION: In people ≥80 years, cardioembolic stroke is more common, and small vessel disease less common compared to people <80 years. Overall, the results have to be interpreted with caution due to few studies. Large studies using validated classification systems are needed.
RESUMO
Early identification of stroke symptoms is essential. The rate of stroke identification by call-takers at emergency medical communication centres (EMCCs) varies, and patients who are found in a lying down position are often not identified as having an ongoing stroke. OBJECTIVES: this study aimed to explore signs and symptoms of stroke in patients who had fallen or were found in a lying position. DESIGN: a retrospective exploratory qualitative study design was used. METHOD: a total of 29 emergency calls to EMCCs regarding patients discharged with a stroke diagnosis from a large teaching hospital in Stockholm, Sweden, in January-June 2011, were analysed using qualitative content analysis. RESULTS: during the emergency calls, the callers described a sudden change in the patient's health status including signs such as the patient's loss of bodily control, the patient's perception of a change in sensory perception, and the callers' inability to communicate with the patient. CONCLUSIONS: The callers' descriptions of stroke in a person found in a lying position are not always as described in assessment protocols describing the onset of a stroke. Instead, the symptom descriptions are much vaguer. Therefore, to increase identification of stroke during emergency calls, there is a need for an increased understanding of how callers describe stroke symptoms and communicate with the call-takers.
RESUMO
PURPOSE: To describe physical functioning after severe COVID-19-infection. MATERIALS AND METHOD: An explanatory sequential mixed method design was used. Thirty-nine participants performed tests and answered questionnaires measuring physical functioning six months after hospitalisation due to COVID-19. Thirty of these participants participated in semi-structured interviews with questions regarding how they perceived their physical functioning and recovery from COVID-19 at 12 months post-hospitalisation. RESULTS: At six months, physical functioning measured via chair stand test and hip-worn accelerometers was lower than normal reference values. There was a reduction in breathing muscle strength. Participants estimated their functional status during different activities as lower compared to those before COVID-19-infection, measured with a patient-specific functional scale. At one year after infection, there were descriptions of a rough recovery process and remaining symptoms. CONCLUSION: Patients recovering from severe COVID-19 seem to have reduced physical functioning and activity levels, and they perceive their recovery to be slow and difficult. They experienced a lack of clinical support and contradictory advice regarding rehabilitation. Coaching in returning to physical functioning after the infection needs to be better co-ordinated and there is a need for guidelines for health professionals to avoid patients receiving contradictory advice.
Coronavirus infection disease-19 (COVID-19) can have a great impact on a person's physical functioning.In the early course of the COVID-19 pandemic there were not any clear guidelines regarding rehabilitation for this group of patients.As some people with COVID-19 may have impairments in their physical functioning up to one year after leaving hospital there is a need to provide rehabilitation.

PURPOSE: To perform a meta-analysis on how the admissions of stroke and transient ischemic attack (TIA) changed during the Corona Virus infection-19 (COVID-19) pandemic and evaluate if the effect was depending on stroke severity. METHODS: Observational cohort studies comparing the number of stroke and/or TIA admissions during a period of the pandemic compared to a period before the pandemic were identified in PubMed and Embase. After excluding studies with overlapping populations and studies without satisfactory case ascertainment, data was extracted and meta-analyzed. FINDINGS: A total of 59 studies were included. During the pandemic, there was a decrease in admissions of ischemic stroke (admission rate ratio (ARR) = 0.77, 95% confidence interval (CI): 0.72, 0.82), intracerebral hemorrhage (ARR = 0.79, 95% CI: 0.70, 0.90) and TIA (ARR = 0.66, 95% CI: 0.58, 0.75). Albeit admission rates of both mild (ARR = 0.61, 95% CI: 0.49, 0.77) and severe (ARR = 0.82, 95% CI = 0.71, 0.95) strokes decreased, milder strokes decreased more (proportion ratio (PR) = 0.76, 95% CI: 0.65, 0.89). DISCUSSION: Potential causes for the admission reduction could be strict prioritizations within the health care, patients' fear of acquiring COVID-19, or decreased access to health care due to lockdowns. CONCLUSION: During the COVID-19 pandemic, there was a reduction in admissions of stroke and TIA, possibly caused by reluctance to seek medical care.

Healthy living with physical activity, healthy eating habits, no smoking, and no alcohol overuse have an important role in primary and secondary stroke prevention. Further secondary prevention depends on type and cause of stroke or TIA. After intracerebral bleeding, ischemic stroke or TIA, preventive pharmacological therapies include antihypertensive drugs. After ischemic stroke or TIA, treatment with antithrombotics (oral anticoagulants or antiplatelets) and statins is recommended. In stroke due to unusual causes, the pharmacological preventive treatment described above may need modification. For symptomatic carotid stenosis, carotid surgery is recommended, preferably within the first 14 days after onset. A surgical preventive treatment is closure of patent foramen ovale in patients aged 18-60 years with ischemic stroke of unknown cause.

Rehabilitation is a key aspect of the treatment of stroke patients, both acute and in later phases. The patients' needs varies between individuals and over time. Several skills and methods and different professionals working together in teams, as well as coordination along the entire chain of care, are required in order to meet those different needs. Early supported discharge, ESD, is recommended for patients with mild to moderate stroke. Stroke is a chronic disease requiring lifelong structured follow-up focusing not only on medical treatment but also on lifestyle, mental and physical well-being and activity and participation.

Background Stroke incidence, care, and survival show continuous improvements in Sweden, including no or decreasing disparities between men and women. In this study, we aimed to estimate and compare the risk of stroke recurrence in men and women over time, accounting for the competing risk of death. Methods and Results We included adult patients with first-time stroke (ischemic or intracerebral hemorrhage) registered in Riksstroke (the Swedish Stroke Register), 2012 to 2020, and followed until December 2020. Stroke recurrences included new events registered in Riksstroke from 28 days after stroke. To account for the competing risk of death, we used the cumulative incidence function to estimate crude incidences, and multivariable Cox regression to estimate cause-specific hazard ratios (HRs) adjusting for differences in patients' risk factor profiles. The study included 72 148 (53.5%) men and 62 689 (46.5%) women. We observed 10 925 stroke recurrences and 81 811 deaths following the initial 28 days after the first stroke. The cumulative incidence of stroke recurrence was 3.7% (95% CI, 3.6-3.8) after 1 year, 7.0 (95% CI, 6.8-7.1) after 3 years, and 9.1% (95% CI, 8.9-9.3) after 5 years. The incidence decreased substantially during the study period (HR, 2019-2020 versus 2012, 0.824 [95% CI, 0.759-0.894]). Overall, men had a lower risk of stroke recurrence. After adjustments for differences in patient characteristics, men had a slightly higher risk of recurrence (of any type) after an ischemic stroke (HR, 1.090 [95% CI, 1.045-1.138]) and a lower risk after hemorrhagic stroke (HR, 0.880 [95% CI, 0.781-0.991]) compared with women. Conclusions The risk of stroke recurrence has decreased in both men and women. Women's higher age and other differences in risk factors partly explain their higher risk of stroke recurrence compared with men.

BACKGROUND: Endovascular thrombectomy (EVT) for ischemic stroke (IS) beyond 6 hours has been proven effective in randomized controlled trials. We present data on implementation and outcomes for EVT beyond 6 hours in Sweden. METHODS: We included all cases of anterior circulation IS caused by occlusion of the intracranial carotid artery, and the M1 or M2 segment of the middle cerebral artery, registered in two nationwide quality registers for stroke in 2015-2020. Three groups were defined from onset-to-groin-puncture (OTG) time: early window (<6 hours), late window (6-24 hours) known onset, late window last seen well (LSW). Favorable outcome (modified Rankin Scale (mRS) 0-2) and all-cause mortality at 90 days were the main outcomes, and symptomatic intracerebral hemorrhage (sICH) was the safety outcome. RESULTS: Late window EVT increased from 0.3% of all IS in 2015 to 1.8% in 2020, and from 17.4% of all anterior circulation EVTs in 2015 to 32.9% in 2020. Of 2199 patients, 76.9% (n=1690) were early window EVTs and 23.1% late window EVTs (n=509; 141 known onset, 368 LSW). Median age was 73 years, and 46.2% were female, with no differences between groups. Favorable outcome did not differ between groups (early window 42.4%, late window known onset 38.9%, late window LSW 37.3% (p=0.737)) and remained similar when adjusted for baseline differences. sICH rates did not differ (early window 4.0%, late window known onset 2.1%, late window LSW 4.9% (p=0.413)). CONCLUSION: Late window EVTs have increased substantially over time, and currently account for one third of anterior circulation treatments. Early and late window patients had similar outcomes.

BACKGROUND: Endovascular thrombectomy (EVT) is standard of care for anterior circulation acute ischemic stroke (AIS) caused by large vessel occlusion (LVO), but data on nationwide performance in routine healthcare are sparse. The study aims were to describe EVT patients with LVO AIS, analyze mortality and functional outcome, and compare results with randomized controlled trials (RCTs). METHODS: Data from the Riksstroke and the Swedish Endovascular Treatment of Acute Stroke Registry (RSEVAS) on pre-stroke independent patients, with LVO AIS in 2017-2019, defined as occlusion of the intracranial internal carotid artery, or the M1 or M2 segments of the middle cerebral artery, and groin puncture <6â h of onset, were compared to aggregated HERMES collaboration RCT data. We assessed 90-day survival and function, defined by the modified Rankin Scale. Specific analyzes were stratified by occlusion location. RESULTS: In all, 1011/2560 of RSEVAS patients matched RCT inclusion criteria. Compared with RCT data, patients were older (73 vs. 68), fewer received intravenous thrombolysis (63.1% vs. 83%), and M2 occlusions were more common (24.5% vs. 8%). 90-day survival in RSEVAS was 85.3%, 42.8% achieved good outcome and 5% had symptomatic intracerebral hemorrhage (sICH). Corresponding outcomes in RCT data were 84.7% survival, 46% good outcome, and 4.4% sICH. Functional outcome was most favorable following M2 occlusions. CONCLUSIONS: EVT patients from our large real-world national dataset differed from RCT patients in several baseline factors including distribution of vascular occlusion site. However, the overall outcome of EVT in our Swedish cohort appeared to well match the pivotal trial findings.

Introduction: The Stockholm Stroke Triage System (SSTS) is a prehospital triage system for detection of patients eligible for endovascular thrombectomy (EVT). Assessment of hemiparesis combined with ambulance-hospital teleconsultation is used to route patients directly to the thrombectomy centre. Some patients are not identified and require secondary transport for EVT (undertriage) while others taken to the thrombectomy centre do not undergo EVT (overtriage). The aims of this study were to characterize mistriaged patients, model for and evaluate alternative triage algorithms. Patients and methods: Patients with suspected stroke transported by priority 1 ground ambulance between October 2017 and October 2018 (n = 2905) were included. Three triage algorithms were modelled using prehospital data. Decision curve analysis was performed to calculate net benefit (correctly routing patients for EVT without increasing mistriage) of alternative models vs SSTS. Results: Undertriage for EVT occurred in n = 35/2582 (1.4%) and overtriage in n = 239/323 (74.0%). Compared to correct thrombectomy triages, undertriaged patients were younger and had lower median NIHSS (10 vs 18), despite 62.9% with an M1 occlusion. In overtriaged patients, 77.0% had a stroke diagnosis (29.7% haemorrhagic). Hemiparesis and FAST items face and speech were included in all models. Decision curve analysis showed highest net benefit for SSTS for EVT, but lower for large artery occlusion (LAO) stroke. Discussion: Undertriaged patients had lower NIHSS, likely due to better compensated proximal occlusions. SSTS was superior to other models for identifying EVT candidates, but lacked information allowing comparison to other prehospital scales. Conclusion: Using prehospital data, alternative models did not outperform the SSTS in finding EVT candidates.
RESUMO
BACKGROUND: Stroke incidence is decreasing in most developing countries. However, worrisome trends of an increase in the younger population have been described. AIM: To investigate sex differences and longitudinal changes in ischemic stroke regarding incidence, cardiovascular risk factors, and outcome, in the young. METHODS: This is an observational study based on the data from the Swedish national stroke registry, Riksstroke. Patients, 18-54 years of age, having ischemic stroke between 2005 and 2018 were included, resulting in a study population of 16,210 patients. RESULTS: The incidence was higher in men than in women (30.6 vs. 19.1 per 100,000, P < 0.001). After an initial increase, the incidence stabilized and then decreased, resulting in a similar level in 2018 as in 2005. Atrial fibrillation, diabetes, and usage of anti-hypertensives at stroke onset were more common among men and did not change over time. Smoking was common and slightly more so in women, but with a reduced prevalence in both men and women during the study period. Dependency in Activities of Daily Living (ADL) and case fatality showed no clear trends or sex differences. CONCLUSIONS: The results show that there are sex differences in ischemic stroke in the younger age group regarding incidence and vascular risk factors, particularly smoking. Temporal trends in stroke incidence are difficult to interpret as fluctuations are substantial, largely due to stroke being quite uncommon in the younger population.
RESUMO
This review describes the evolution of endovascular treatment for acute ischemic stroke, current state of the art, and the challenges for the next decade. The rapid development of endovascular thrombectomy (EVT), from the first attempts into standard of care on a global scale, is one of the major achievements in modern medicine. It was possible thanks to the establishment of a scientific framework for patient selection, assessment of stroke severity and outcome, technical development by dedicated physicians and the MedTech industry, including noninvasive imaging for patient selection, and radiological outcome evaluation. A series of randomized controlled trials on EVT in addition to intravenous thrombolytics, with overwhelmingly positive results for anterior circulation stroke within 6 h of onset regardless of patient characteristics with a number needed to treat of less than 3 for any positive shift in outcome, paved the way for a rapid introduction of EVT into clinical practice. Within the "extended" time window of 6-24 h, the effect has been even greater for patients with salvageable brain tissue according to perfusion imaging with a number needed to treat below 2. Even so, EVT is only available for a small portion of stroke patients, and successfully recanalized EVT patients do not always achieve excellent functional outcome. The major challenges in the years to come include rapid prehospital detection of stroke symptoms, adequate clinical and radiological diagnosis of severe ischemic stroke cases, enabling effective recanalization by EVT in dedicated angiosuites, followed by personalized post-EVT stroke care.

Importance: There is little evidence to guide the choice of antiseizure medication (ASM) for patients with poststroke epilepsy. Theoretical concerns about detrimental effects of ASMs on survival exist. Enzyme-inducing drugs could interfere with secondary stroke prevention. The US Food and Drug Administration recently issued a safety announcement about the potential proarrhythmic properties of lamotrigine. Objective: To investigate whether mortality varies with specific ASMs among patients with poststroke epilepsy. Design, Setting, and Participants: A cohort study was conducted using individual-level data from linked registers on all adults in Sweden with acute stroke from July 1, 2005, to December 31, 2010, and subsequent onset of epilepsy before December 31, 2014. A total of 2577 patients receiving continuous ASM monotherapy were eligible for the study. Data were analyzed between May 27, 2019, and April 8, 2021. Exposures: The dispensed ASM (Anatomical Therapeutic Chemical code N03A) determined exposure status, and the first dispensation date marked the start of treatment. Main Outcomes and Measures: The primary outcome, all-cause death, was analyzed using Cox proportional hazards regression with carbamazepine as the reference. Cardiovascular death (International Statistical Classification of Diseases and Related Health Problems, Tenth Revision codes I0-I99 as the underlying cause) was assessed using Fine-Gray competing risk regression models. Results: A total of 2577 patients (1400 men [54%]; median age, 78 years [IQR, 69-85 years]) were included. The adjusted hazard ratio of all-cause death compared with carbamazepine was 0.72 (95% CI, 0.60-0.86) for lamotrigine, 0.96 (95% CI, 0.80-1.15) for levetiracetam, 1.40 (95% CI, 1.23-1.59) for valproic acid, 1.16 (95% CI, 0.88-1.51) for phenytoin, and 1.16 (95% CI, 0.81-1.66) for oxcarbazepine. The adjusted hazard ratio of cardiovascular death compared with carbamazepine was 0.76 (95% CI, 0.61-0.95) for lamotrigine, 0.77 (95% CI, 0.60-0.99) for levetiracetam, 1.40 (95% CI, 1.19-1.64) for valproic acid, 1.02 (95% CI, 0.71-1.47) for phenytoin, and 0.71 (95% CI, 0.42-1.18) for oxcarbazepine. Conclusions and Relevance: This cohort study's findings suggest differences in survival between patients treated with different ASMs for poststroke epilepsy. Patients receiving lamotrigine monotherapy had significantly lower mortality compared with those receiving carbamazepine. The opposite applied to patients prescribed valproic acid, who had a higher risk of cardiovascular and all-cause death. Levetiracetam was associated with a reduced risk of cardiovascular death compared with carbamazepine, but there was no significant difference in overall mortality.

BACKGROUND AND PURPOSE: The Stockholm Stroke Triage System (SSTS) is a prehospital algorithm for detection of endovascular thrombectomy (EVT)-eligible patients, combining symptom severity assessment and ambulance-to-hospital teleconsultation, leading to a decision on primary stroke center bypass. In the Stockholm Region (6 primary stroke centers, 1 EVT center), SSTS implementation in October 2017 reduced onset-to-EVT time by 69 minutes. We compared clinical outcomes before and after implementation of SSTS in an observational study. METHODS: We prospectively recruited patients transported by Code Stroke ambulance within the Stockholm region under the SSTS, treated with EVT during October 2017 to October 2019, and compared to EVT patients from 2 previous years. OUTCOMES: shift in modified Rankin Scale (mRS) scores, mRS score 0 to 1, mRS score 0 to 2, and death (all 3 months), National Institutes of Health Stroke Scale (NIHSS) score change 24-hour post-EVT, recanalization (Thrombolysis in Cerebral Infarction 2b-3), and symptomatic intracranial hemorrhage. mRS outcomes were adjusted for age and baseline NIHSS. RESULTS: Patients with EVT in the SSTS group (n=244) were older and had higher baseline NIHSS versus historical controls (n=187): median age 74 (interquartile range, 63-81) versus 71 (61-78); NIHSS score 17 (11.5-21) versus 15 (10-20). During SSTS, median onset-to-puncture time was 136 versus 205 minutes (P<0.001). Adjusted common odds ratio for lower mRS in SSTS patients was 1.7 (95% CI, 1.2-2.3) versus controls. During SSTS, 83/240 (34.6%) versus 44/186 (23.7%) reached 3-month mRS score 0 to 1 (P=0.014), adjusted common odds ratio 2.3 (95% CI, 1.4-3.6). Median NIHSS change 24-hour post-EVT was 6 versus 4 (P=0.005). Differences in Thrombolysis in Cerebral Infarction, symptomatic intracranial hemorrhage, and death were nonsignificant. CONCLUSIONS: With an onset to arterial puncture time reduction by 69 minutes, outcomes in thrombectomy-treated patients improved significantly after region-wide large artery occlusion triage system implementation. These results warrant replication studies in other geographic and organizational circumstances.

BACKGROUND AND AIM: To describe the utilization of the first antiepileptic drug (AED) in men and women with previous stroke in a nationwide population. METHODS: Prescription data, patient's age, and sex were collected from the Swedish Drug Register and cross-linked to diagnosis data from the National Patient Register and data from Statistics Sweden. Patients with a first dispensation of an AED after stroke between 1 January 2007 and 31 December 2014 were included. RESULTS: A total of 10 958 patients with stroke were initiated on AED treatment (51% women, mean age 75 years). Gabapentin (n = 3073, 28%), pregabalin (n = 2476, 22%), carbamazepine (n = 2330, 21%), levetiracetam (n = 1158, 10%), and valproic acid (n = 833, 7%) were the most dispensed AEDs. After stratification by the presence of a neuropathic pain diagnosis, gabapentin, and pregabalin were the most used AEDs. In contrast, after stratification for epilepsy/convulsions diagnosis, carbamazepine and levetiracetam were the most initiated AEDs. CONCLUSION: This study suggests that AED is mainly used for neuropathic/poststroke pain and the study shows gabapentin and pregabalin to be the most used AEDs. For epilepsy, carbamazepine and levetiracetam were the most used AEDs in patients with previous stroke.
RESUMO
Background and Purpose: Previous studies of stroke management and outcome in Sweden have revealed differences between men and women. We aimed to analyze if differences in stroke incidence, care, and outcome have altered over time. Methods: All stroke events registered in the Swedish Stroke Register 2005 to 2018 were included. Background variables and treatment were collected during the acute hospital stay. Survival data were obtained from the national cause of death register by individual linkage. We used unadjusted proportions and estimated age-adjusted marginal means, using a generalized linear model, to present outcome. Results: We identified 335 183 stroke events and a decreasing incidence in men and women 2005 to 2018. Men were on average younger than women (73.3 versus 78.1 years) at stroke onset. The age-adjusted proportion of reperfusion therapy 2005 to 2018 increased more rapidly in women than in men (2.3%15.1% in men versus 1.4%16.9% in women), but in 2018, women still had a lower probability of receiving thrombolysis within 30 minutes. Among patients with atrial fibrillation, oral anticoagulants at discharge increased more rapidly in women (31.2%78.6% in men versus 26.7%81.9% in women). Statins remained higher in men (36.9%83.7% in men versus 32.3%81.2% in women). Men had better functional outcome and survival after stroke. After adjustment for women's higher age, more severe strokes, and background characteristics, the absolute difference in functional outcome was <1% and survival did not differ. Conclusions: Stroke incidence, care, and outcome show continuous improvements in Sweden, and previously reported differences between men and women become less evident. More severe strokes and older age in women at stroke onset are explanations to persisting differences.

BACKGROUND: Stroke and dementia are interrelated diseases and risk for both increases with age. Even though stroke incidence and age-standardized death rates have decreased due to prevention of stroke risk factors, increased utilization of reperfusion therapies, and other changes in healthcare, the absolute numbers are increasing due to population growth and aging. OBJECTIVE: To analyze predictors of death after stroke in patients with dementia and investigate possible time and treatment trends. METHODS: A national longitudinal cohort study 2007-2017 using Swedish national registries. We compared 12,629 ischemic stroke events in patients with dementia with matched 57,954 stroke events in non-dementia controls in different aspects of patient care and mortality. Relationship between dementia status and dementia type (Alzheimer's disease and mixed dementia, vascular dementia, other dementias) and death was analyzed using Cox regressions. RESULTS: Differences in receiving intravenous thrombolysis between patients with and without dementia disappeared after the year 2015 (administered to 11.1% dementia versus 12.3% non-dementia patients, pâ=â0.117). One year after stroke, nearly 50% dementia and 30% non-dementia patients had died. After adjustment for demographics, mobility, nursing home placement, and comorbidity index, dementia was an independent predictor of death compared with non-dementia patients (HR 1.26 [1.23-1.29]). CONCLUSION: Dementia before ischemic stroke is an independent predictor of death. Over time, early and delayed mortality in patients with dementia remained increased, regardless of dementia type. Patients with≤80 years with prior Alzheimer's disease or mixed dementia had higher mortality rates after stroke compared to patients with prior vascular dementia.
