- Introduction: Scarce data exist on the etiology of recurrent ischemic strokes (ISs) among young adults. We analyzed the etiology of first-ever and recurrent events and the differences between them.Patients and methods: Patients aged 15-49 years with a first-ever IS in 1994-2007 were included in the Helsinki Young Stroke Registry. In this retrospective cohort study, data on recurrent ISs were identified from Care Register for Health Care until the end of 2017 and Causes of Death Register and from patient records until the end of 2020. All first-ever and recurrent ISs were classified using Atherosclerosis-Small vessel disease-Cardioembolism-Other Cause (A-S-C-O) and Trial of Org 10172 in Acute Stroke Treatment (TOAST) classifications.Results: A total of 970 patients were included (median age at index IS 46 years, interquartile range 43-48, 33% women), of which 155 (16.0%) patients had recurrent IS, with 8 (5.2%) fatal cases and 5 (3.2%) unverifiable cases. The median follow-up was 17.4 (IQR 13.9-21.7) years. Median time from the index event to the first recurrent event was 4.5 (interquartile range [IQR] 1.6-10.2) years. Recurrence was more often due to definite cardioembolism (10.7% vs 18.0%, p = 0.013), while the proportion of other definite A-S-C-O subgroups remained the same. With TOAST classification, the proportion of true cryptogenic ISs decreased (16.7% vs 6.7%, p = 0.003), while those with incomplete evaluation increased (9.3% vs 19.3%, p = 0.015). Other TOAST phenotypes remained the same.Conclusion: The proportion of definite cardioembolism increased at recurrence using the A-S-C-O classification and the number of cryptogenic ISs decreased using the TOAST classification, while cases with incomplete evaluation increased. Most etiologies remained the same.

- Introduction: Limited data exist on the outcome of pregnancies and deliveries in women with ischaemic stroke. We investigated the incidence of pregnancy- and delivery-related complications in women with ischaemic stroke before and after pregnancy compared with stroke-free matched controls. Patients and methods: Of our 1008 consecutive patients aged 15–49 years with first-ever ischaemic stroke, 1994– 2007, we included women with pregnancy data before or after stroke recorded in the Medical Birth Register (MBR) (n¼152), and for them searched stroke-free controls matched by age, parity, year of birth, residential area and multiplicity (n¼608). Data on hospital admissions and deaths (1987–2014) came from national health registries. Poisson regression mixed models allowed comparison of the incidence of complications. Results: A total of 124 stroke mothers had 207 singleton pregnancies before and 45 mothers 68 pregnancies after stroke. The incidence rate ratio (IRR) for the composite outcome of pregnancy and delivery complications adjusted for socioeconomic status and maternal smoking was 1.43 (95% confidence interval [CI] 1.00–2.03, p¼0.05) for pre-stroke mothers, and 1.09 (95% CI 0.66–1.78) for post-stroke mothers, compared with matched controls. Similarly, the adjusted IRR for post-stroke hospital admission during pregnancy was 1.85 (95% CI 1.03–3.31). The IRR for perinatal death of the child was 3.43 (95% CI 0.57–20.53) before and 8.88 (95% CI 0.81–97.95) after stroke. Discussion and conclusions: Compared with stroke-free mothers, we found a higher incidence of pregnancy- and delivery-related complications in mothers with ischaemic stroke. Larger studies are needed to verify our results.

- The purpose of the European Stroke Organisation-Karolinska Stroke Update Conference is to provide updates on recent stroke therapy research and to give an opportunity for the participants to discuss how these results may be implemented into clinical routine. The meeting started 22 years ago as Karolinska Stroke Update, but since 2014 it is a joint conference with European Stroke Organisation. Importantly, it provides a platform for discussion on the European Stroke Organisation guidelines process and on recommendations to the European Stroke Organisation guidelines committee on specific topics. By this, it adds a direct influence from stroke professionals otherwise not involved in committees and work groups on the guideline procedure. The discussions at the conference may also inspire new guidelines when motivated. The topics raised at the meeting are selected by the scientific programme committee mainly based on recent important scientific publications. This year's European Stroke Organisation-Karolinska Stroke Update Meeting was held in Stockholm on 11-13 November 2018. There were 11 scientific sessions discussed in the meeting including two short sessions. Each session except the short sessions produced a consensus statement (Full version with background, issues, conclusions and references are published as web-material and at www.eso-karolinska.org and http://eso-stroke.org) and recommendations which were prepared by a writing committee consisting of session chair(s), scientific secretary and speakers. These statements were presented to the 250 participants of the meeting. In the open meeting, general participants commented on the consensus statement and recommendations and the final document were adjusted based on the discussion from the general participants Recommendations (grade of evidence) were graded according to the 1998 Karolinska Stroke Update meeting with regard to the strength of evidence. Grade A Evidence: Strong support from randomised controlled trials and statistical reviews (at least one randomised controlled trial plus one statistical review). Grade B Evidence: Support from randomised controlled trials and statistical reviews (one randomised controlled trial or one statistical review). Grade C Evidence: No reasonable support from randomised controlled trials, recommendations based on small randomised and/or non-randomised controlled trials evidence.

- The SITS-UTMOST (Safe Implementation of Thrombolysis in Upper Time window Monitoring Study) was a registry-based prospective study of intravenous alteplase used in the extended time window (3–4.5 h) in acute ischaemic stroke to evaluate the impact of the approval of the extended time window on routine clinical practice. Patients and methods Inclusion of at least 1000 patients treated within 3–4.5 h according to the licensed criteria and actively registered in the SITS-International Stroke Thrombolysis Registry was planned. Prospective data collection started 2 May 2012 and ended 2 November 2014. A historical cohort was identified for 2 years preceding May 2012. Clinical management and outcome were contrasted between patients treated within 3 h versus 3–4.5 h in the prospective cohort and between historical and prospective cohorts for the 3 h time window. Outcomes were functional independency (modified Rankin scale, mRS) 0–2, favourable outcome (mRS 0–1), and death at 3 months and symptomatic intracerebral haemorrhage (SICH) per SITS. Results 4157 patients from 81 centres in 12 EU countries were entered prospectively ( N = 1118 in the 3–4.5 h, N = 3039 in the 0–3 h time window) and 3454 retrospective patients in the 0–3 h time window who met the marketing approval conditions. In the prospective cohort, median arrival to treatment time was longer in the 3–4.5 h than 3 h window (79 vs. 55 min). Within the 3 h time window, treatment delays were shorter for prospective than historical patients (55 vs. 63). There was no significant difference between the 3–4.5 h versus 3 h prospective cohort with regard to percentage of reported SICH (1.6 vs. 1.7), death (11.6 vs. 11.1), functional independency (66 vs. 65) at 3 months or favourable outcome (51 vs. 50). Discussion Main weakness is the observational design of the study. Conclusion This study neither identified negative impact on treatment delay, nor on outcome, following extension of the approved time window to 4.5 h for use of alteplase in stroke.

- Background and aims: Stroke symptoms vary and could be hard to recognize. In addition, stroke severity has decreased according to the National Institutes of Health Stroke Scale (NISSH), with less pronounced symptoms expression. Knowledge on the patient’s description of stroke symptoms is therefore needed. The aim was to describe patient’s symptoms at stroke onset.Methods: A qualitative content analysis was used. Data were collected through individual interviews with 27 patients (16 men and 11 women, median age 70.4 years). All patients were hospitalized with a first-time stroke. The interviews were conducted within 4 weeks of symptoms onset and before hospital discharge.Results: All patients had symptoms that affected their daily life. Some patients described having multiple symptoms at the same time, others had symptoms that began insidiously and worsened over time. Symptoms such as overwhelming fatigue or nausea were described as Premonition of becoming ill, feeling unwell or that something was wrong. Motoric bodily changes were multifaceted as slurred speech or dizziness, balance difficulties and losing control of the body or motor dysfunction. But also, that the surroundings were distorted, and solid objects moved around. Symptoms of Dazed and affected senses included confusion and visual impairment or headache.Conclusions: Stroke is a complex disease with several different symptoms’ expressions and could be difficult to recognize, especially when symptoms are less typical or perceived as not serious. Increased awareness of stroke symptoms among caregivers and among members of the community is important and needed.

- Introduction: Atrial fibrillation is an independent risk factor of thromboembolism. Women with atrial fibrillation are at a higher overall risk for stroke compared to men with atrial fibrillation. The aim of this study was to evaluate for sex differences in patients with acute stroke and atrial fibrillation, regarding risk factors, treatments received and outcomes. Methods: Data were analyzed from the ‘‘Recurrence and Cerebral Bleeding in Patients with Acute Ischemic Stroke and Atrial Fibrillation’’ (RAF-study), a prospective, multicenter, international study including only patients with acute stroke and atrial fibrillation. Patients were followed up for 90 days. Disability was measured by the modified Rankin Scale (0–2 favorable outcome, 3–6 unfavorable outcome). Results: Of the 1029 patients enrolled, 561 were women (54.5%) (p<0.001) and younger (p<0.001) compared to men. In patients with known atrial fibrillation, women were less likely to receive oral anticoagulants before index stroke (p¼0.026) and were less likely to receive anticoagulants after stroke (71.3% versus 78.4%, p¼0.01). There was no observed sex difference regarding the time of starting anticoagulant therapy between the two groups (6.411.7 days for men versus 6.512.4 days for women, p¼0.902). Men presented with more severe strokes at onset (mean NIHSS 9.26.9 versus 8.17.5, p<0.001). Within 90 days, 46 (8.2%) recurrent ischemic events (stroke/TIA/systemic embolism) and 19 (3.4%) symptomatic cerebral bleedings were found in women compared to 30 (6.4%) and 18 (3.8%) in men (p¼0.28 and p¼0.74). At 90 days, 57.7% of women were disabled or deceased, compared to 41.1% of the men (p<0.001). Multivariate analysis did not confirm this significance. Conclusions: Women with atrial fibrillation were less likely to receive oral anticoagulants prior to and after stroke compared to men with atrial fibrillation, and when stroke occurred, regardless of the fact that in our study women were younger and with less severe stroke, outcomes did not differ between the sexes.

End of life after stroke : a nationwide study of 42,502 deaths occurring within a year after stroke
- 2018
-

Tidskriftsartikel (refereegranskat)abstract
- Introduction: In the scientific literature, there is very limited empirical information on end-of-life issues after stroke in the scientific literature. The present nationwide study describes the circumstances surrounding deaths that occur within a year after a stroke. Patients and methods: Datasets from three nationwide Swedish registers (on stroke, palliative care and cause of death) were linked. Basic information was available for 42,502 unselected cases of death that occurred within a year after a stroke and more detailed information was available for 16,408 deaths. Odds ratios for characteristics of end-of-life care were calculated by logistic regression. Results: In the late phase after stroke (three months to one year), 46% of patients died in a nursing home, whereas 37% of patients died in a hospital after readmission and 10% of patients died at home. Eleven per cent of deaths were reported as being unexpected. A next of kin was present at 49% of deaths. The frequency of unattended deaths (neither next of kin nor staff were present at the time of death) ranged from 5% at home with specialised home care to 25% in hospitals. Discussion: This is, by far, the largest study published on end-of-life issues after stroke. Major differences between countries in healthcare, community services, family structure and culture may limit direct transfer of the present results to other settings. Conclusion: There is considerable discordance between presumed good death' late after stroke (dying at home surrounded by family members) and the actual circumstances at the end of life.

- Long-term risk-factor control and secondary prevention are not well characterized in patients with a first transient ischemic attack (TIA). With baseline levels as reference, we compared primary-care data on blood pressure (BP), low-density lipoprotein cholesterol (LDL-C), smoking, and use of antihypertensives, statins and antiplatelet treatment/oral anticoagulation (APT/OAC) during 5years after a first TIA.Patients in QregPV, a Swedish primary-care register for the Region of Västra Götaland, with a first TIA discharge diagnosis from wards proficient in stroke care 2010 to 2012 were identified and followed up to 5years. BP, LDL-C, smoking, use of antihypertensives, statins, APT/OAC, and achievement of target levels were calculated. We used logistic mixed-effect models to analyze the effect of follow-up over time on risk-factor control and secondary prevention treatment.We identified 942 patients without prior cerebrovascular disease who had a first TIA. Compared to baseline, the first year of follow-up was associated with improvements in concomitant attainment of BP <140/90mmHg, LDL-C<2.6mmol/L and non-smoking, which rose from 20% to 33% (OR 2.08, 95% CI 1.38-3.13), but then stagnated in years 2-5. In the first year of follow-up, 47% of patients had complete secondary prevention treatment (antihypertensives, APT/OAC and statin), but continued follow-up was associated with a yearly decrease in secondary prevention treatment (OR 0.94, 95% CI 0.94-0.98).Risk-factor control was inadequate, leaving considerable potential for improved secondary prevention treatment after a first TIA in Swedish patients followed up to 5years.

- Research has suggested that delivery is associated with an increased risk of stroke in women; however, there is a lack of contemporary estimates on the incidence of stroke in and after pregnancy compared with the baseline risk in women of childbearing age in Sweden. Patients and methods All women aged 15–49 years with live births/stillbirths in 1992–2011 were identified from the Swedish Medical Birth Registry linked with the National Patient Registry. First stroke during the study period was identified. Incidence rates per 100,000 person-years and adjusted incidence rate ratios (IRRs) were calculated for antepartum, peripartum and early and late postpartum periods, compared with all other available follow-up time (time before pregnancy and after postpartum) using Poisson regression adjusted for maternal age, education attainment and calendar time. Results Of 1,124,541 women, 3094 had a first incident stroke (331 occurred during pregnancy or first 12 weeks postpartum), about half having ischaemic stroke. The incidence was 15.0 per 100,000 person-years (95% confidence interval 14.5–15.6) in non-pregnant time. The incidence was lower antepartum (7.3/100,000 person-years, 6.0–8.9; adjusted IRR = 0.7, 0.5–0.8) but higher peripartum (314.4/100,000 person-years, 247.5–399.5; adjusted IRR = 27.3, 21.4–34.9) and early postpartum (64.0/100,000 person-years, 54.1–75.7; adjusted IRR = 5.5, 4.6–6.6). The increased risk in peripartum was more evident for intracerebral haemorrhage than other types of stroke. Conclusion Overall risk of stroke was low in women of childbearing age, but stroke risk peaks in the peripartum and early postpartum periods. Future work should address factors that contribute to this increased risk in order to develop approaches to attenuate risk.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Few studies have reported the characteristics of patients with in-hospital stroke (IHS) including the reason for hospitalization and invasive procedures before the stroke. We aimed to extend current knowledge.PATIENTS AND METHODS: All adult patients with IHS in Sweden during 2010-2019 registered in the Swedish Stroke Register (Riksstroke) were included. The cohort was cross-linked to the National Patient Register and data extracted on background diagnoses, main discharge diagnoses, and procedure codes for the hospitalization when IHS occurred and any hospital-based healthcare contacts within 30 days before IHS.RESULTS: 231,402 stroke cases were identified of which 12,551 (5.4%) were in-hospital and had corresponding entries in the National Patient Register. Of the IHS patients, 11,420 (91.0%) had ischemic stroke and 1131 (9.0%) hemorrhagic stroke; 5860 (46.7%) of the IHS patients had at least one invasive procedure prior to ictus. 1696 (13.5%) had a cardiovascular procedure and 560 (4.5%) a neurosurgical procedure. 1319 (10.5%) patients only had minimally invasive procedures such as blood product transfusion, hemodialysis, or central line insertion. Common discharge diagnosis in patients with no invasive procedures were cardiovascular disorders, injuries, and respiratory disorders.DISCUSSION AND CONCLUSION: One in every 17 strokes in Sweden occur in a hospital. In this unselected large cohort the previously reported major causes for in-hospital stroke, cardiovascular and neurosurgical procedures, preceded IHS in only 18.0% of cases suggesting that other etiologies are more common than previously reported. Future studies should aim at determining absolute risks of stroke after surgical procedures and ways of risk reduction.

- Introduction Approaches to economic evaluations of stroke therapies are varied and inconsistently described. An objective of the European Stroke Organisation (ESO) Health Economics Working Group is to standardise and improve the economic evaluations of interventions for stroke. Methods The ESO Health Economics Working Group and additional experts were contacted to develop a protocol and a guidance document for data collection for economic evaluations of stroke therapies. A modified Delphi approach, including a survey and consensus processes, was used to agree on content. We also asked the participants about resources that could be shared to improve economic evaluations of interventions for stroke. Results Of 28 experts invited, 16 (57%) completed the initial survey, with representation from universities, government, and industry. More than half of the survey respondents endorsed 13 specific items to include in a standard resource use questionnaire. Preferred functional/quality of life outcome measures to use for economic evaluations were the modified Rankin Scale (14 respondents, 88%) and the EQ-5D instrument (11 respondents, 69%). Of the 12 respondents who had access to data used in economic evaluations, 10 (83%) indicated a willingness to share data. A protocol template and a guidance document for data collection were developed and are presented in this article. Conclusion The protocol template and guidance document for data collection will support a more standardised and transparent approach for economic evaluations of stroke care.

- Thrombolysis usage in ischaemic stroke varies across sites. Divergent advice from professional guidelines and product labels may contribute. Patients and methods We analysed SITS-International registry patients enrolled January 2010 through June 2016. We grouped sites into organisational tertiles by number of patients arriving ≤2.5 h and treated ≤3 h, percentage arriving ≤2.5 h and treated ≤3 h, and numbers treated ≤3 h. We assigned scores of 1–3 (lower/middle/upper) per variable and 2 for onsite thrombectomy. We classified sites as lower efficiency (summed scores 3–5), medium efficiency (6–8) or higher efficiency (9–11). Sites were also grouped by adherence with European product label and ESO guideline: ‘label adherent’ (>95% on-label), ‘guideline adherent’ (≥5% off-label, ≥95% on-guideline) or ‘guideline non-adherent’ (>5% off-guideline). We cross-tabulated site-efficiency and adherence. We estimated the potential benefit of universally selecting by ESO guidance, using onset-to-treatment time-specific numbers needed to treat for day 90 mRS 0–1. Results A total of 56,689 patients at 597 sites were included: 163 sites were higher efficiency, 204 medium efficiency and 230 lower efficiency. Fifty-six sites were ‘label adherent’, 204 ‘guideline adherent’ and 337 ‘guideline non-adherent’. There were strong associations between site-efficiency and adherence (P < 0.001). Almost all ‘label adherent’ sites (55, 98%) were lower efficiency. If all patients were treated by ESO guidelines, an additional 17,031 would receive alteplase, which translates into 1922 more patients with favourable three-month outcomes. Discussion Adherence with product labels is highest in lower efficiency sites. Closer alignment with professional guidelines would increase patients treated and favourable outcomes. Conclusion Product labels should be revised to allow treatment of patients ≤4.5 h from onset and aged ≥80 years.

- Background and Aims: Anxiety is associated with decreased quality of life and depression, but gets less attention than other psychological consequences after stroke. The aim was to estimate prevalence of anxiety in the first year after stroke. Method: Searches in EMBASE, MEDLINE, PsycINFO, Cochrane Library, Amed and CINAHL were conducted in May 2015 and April 2017. Included were studies of populations with a hemorrhagic or ischemic stroke or transient ischemic attack, anxiety categorized on a rating scale during the first year after stroke. Two reviewers independently screened and included studies and assessed quality using a checklist. Studies using the Hospital Anxiety and Depression Scale – Anxiety (n 31) were included in a meta- analysis using the random effects model. Heterogeneity was assessed using the Q-test and I2 was used to estimate heterogeneity. Results: Of 4453 titles screened, 37 studies were included comprising 13756 participants with mean ages from 52 to 79 years, assessed within 2 weeks to 1 year after stroke. Most studies were of medium quality. The pooled prevalence of anxiety within the first year was 29.3% [(95% CI 24.8 – 33.8), (I2¼97%, p<0.00001)] which is higher than previously shown. Frequency 0-2 weeks post stroke was 34.8% (95% CI 24.9 – 44.6%), 2 weeks -3 months 23.2 (95% CI 16.3–30.1%) and 3 -12 months 35.6% (95% CI 17.7–54.3. Conclusion: One third of the stroke population may have an anxiety disorder and the prevalence seems to increase, why routine screening may be worth considering in order to provide appropriate interventions.

- Introduction: It is well established that managing patients with acute stroke in dedicated stroke units is associated with improved functioning and survival. The objectives of this study are to investigate whether patients with acute stroke are less likely to be directly admitted to a stroke unit from the Emergency Department when hospital beds are scarce and to measure variation across hospitals in terms of this outcome.Patients and methods: This register study comprised data on patients with acute stroke admitted to 14 out of 72 Swedish hospitals in 2011-2014. Data from the Swedish stroke register were linked to administrative daily data on hospital bed occupancy (measured at 6 a.m.). Logistic regression analysis was used to analyse the association between bed occupancy and direct stroke unit admission.Results: A total of 13,955 hospital admissions were included; 79.6% were directly admitted to a stroke unit from the Emergency Department. Each percentage increase in hospital bed occupancy was associated with a 1.5% decrease in odds of direct admission to a stroke unit (odds ratio = 0.985, 95% confidence interval = 0.978-0.992). The best-performing hospital exhibited an odds ratio of 3.8 (95% confidence interval = 2.6-5.5) for direct admission to a stroke unit versus the reference hospital.Discussion and conclusion: We found an association between hospital crowding and reduced quality of care in acute stroke, portrayed by a lower likelihood of patients being directly admitted to a stroke unit from the Emergency Department. The magnitude of the effect varied considerably across hospitals.

- Background and Aims: Results from prior studies of risk factors for intracerebral hemorrhage (ICH) are inconsistent. Few studies have investigated risk factors measured before the event and separately for different locations of ICH. We investigated risk factors for incident ICH in the population-based Malmö Diet and Cancer cohort. Method: Baseline information, assessed by a questionnaire and in a physical examination, was gathered from 28,416 subjects without a history of ICH. ICH cases (n=333) were identified using local and national patient registers during follow-up (mean follow-up time 18.4 years), validated by review of hospital records, and classified as lobar or non-lobar. Potential risk factors were studied using Cox regression. Results: The following factors were significantly (p

- The association between cholesterol levels and cerebral edema (CED) or hemorrhagic transformation (HT) as an expressions of blood-brain barrier (BBB) dysfunction after ischemic stroke is not well established. The aim of this study is to determine the association of total cholesterol (TC) levels with the incidence of HT and CED after reperfusion therapies. Methods: We analyzed SITS Thrombolysis and Thrombectomy Registry data from January 2011 to December 2017. We identified patients with data on TC levels at baseline. TC values were categorized in three groups (reference group ⩾200 mg/dl). The two primary outcomes were any parenchymal hemorrhage (PH) and moderate to severe CED on follow up imaging. Secondary outcomes included death and functional independence (mRS 0–2) at 3 months. Multivariable logistic regression analysis adjusted for baseline factors including statin pretreatment was used to assess the association between TC levels and outcomes. Results: Of 35,314 patients with available information on TC levels at baseline, 3372 (9.5%) presented with TC levels ⩽130 mg/dl, 8203 (23.2%) with TC 130–200 mg/dl and 23,739 (67.3%) with TC ⩾ 200 mg/dl. In the adjusted analyses, TC level as continuous variable was inversely associated with moderate to severe CED (OR 0.99, 95% CI 0.99–1.00, p = 0.025) and as categorical variable lower TC levels were associated with a higher risk of moderate to severe CED (aOR 1.24, 95% CI 1.10–1.40, p = 0.003). TC levels were not associated with any PH, functional independence, and mortality at 3 months. Conclusions: Our findings indicate an independent association between low levels of TC and higher odds of moderate/severe CED. Further studies are needed to confirm these findings.

- Introduction: Recent trials report positive results for preventing vascular events with dual antiplatelet therapy (DAPT) in patients with high-risk TIA or minor ischemic stroke. We aimed to investigate this population regarding influence of age on vascular risk factors, hospital stay and mortality.Patients and methods: Data on patients aged 40-100 years with TIA or ischemic stroke in the Swedish Stroke Register during 2012-13 were linked with national registers. To identify patients with high-risk TIA (ABCD(2) >= 6) or minor ischemic stroke (NIHSS <= 5) eligible for DAPT, we excluded patients with atrial fibrillation, anticoagulant use, prior major bleeding, or unknown stroke severity.Findings: We identified 10,053 potential DAPT-candidates (mean age 72.6 years, 45.2% female, 16.4% with TIA). With advancing age, most vascular risk factors increased. Antiplatelet treatment increased from 31.9% before the event to 95.5% after discharge. Within 1 year following index event, the proportion of patients with >= 1 re-admission increased with age (29.2% in 40-64 year-olds; 47.2% in 85-100 year-olds). All-cause death per 100 person-years was 6.9 (95% CI 6.4-7.4) within 1 year, and highest in the first 30 days (15.2; 95% CI 12.8-18.2). For each year of increased age, the risk of death increased with 3.5% (p = 0.128) in patients 40-64 years and with 11.8% (p < 0.001) in those >= 85 years.Conclusions: While in theory representing a subset of patients with mild injury, our observational study highlights substantial use of health-care resources and high mortality rates among patients with high-risk TIA or minor ischemic stroke assumed eligible for DAPT.

- 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.

- Background: Embolic strokes of undetermined source comprise up to 20% of ischemic strokes. The stroke recurrence rate is substantial with aspirin, widely used for secondary prevention. The New Approach riVaroxaban Inhibition of Factor Xa in a Global trial versus ASA to prevenT Embolism in Embolic Stroke of Undetermined Source international trial will compare the efficacy and safety of rivaroxaban, an oral factor Xa inhibitor, versus aspirin for secondary prevention in patients with recent embolic strokes of undetermined source. Main hypothesis: In patients with recent embolic strokes of undetermined source, rivaroxaban 15 mg once daily will reduce the risk of recurrent stroke (both ischemic and hemorrhagic) and systemic embolism (primary efficacy outcome) compared with aspirin 100 mg once daily. Design: Double-blind, randomized trial in patients with embolic strokes of undetermined source, defined as nonlacunar cryptogenic ischemic stroke, enrolled between seven days and six months from the qualifying stroke. The planned sample size of 7000 participants will be recruited from approximately 480 sites in 31 countries between 2014 and 2017 and followed for a mean of about two years until at least 450 primary efficacy outcome events have occurred. The primary safety outcome is major bleeding. Two substudies assess (1) the relative effect of treatments on MRI-determined covert brain infarcts and (2) the biological underpinnings of embolic strokes of undetermined source using genomic and biomarker approaches. Summary: The New Approach riVaroxaban Inhibition of Factor Xa in a Global trial versus ASA to prevenT Embolism in Embolic Stroke of Undetermined Source trial is evaluating the benefits and risks of rivaroxaban for secondary stroke prevention in embolic strokes of undetermined source patients. Main results are anticipated in 2018.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The aim of this study was to assess sensitivity, specificity and interrater reliability of phase-contrast MRI (PC-MRI) for diagnosing carotid near-occlusion. Patients and methods: Prospective cross-sectional study conducted between 2018 and 2021. We included participants with suspected 50%–100% carotid stenosis on at least one side, all were examined with CT angiography (CTA) and PC-MRI and both ICAs were analyzed. Degree of stenosis on CTA was the reference test. PC-MRI-based blood flow rates in extracranial ICA and intracranial cerebral arteries were assessed. ICA-cerebral blood flow (CBF) ratio was defined as ICA divided by sum of both ICAs and Basilar artery. Results: We included 136 participants. The ICAs were 102 < 50% stenosis, 88 conventional ⩾50% stenosis (31 with ⩾70%), 49 near-occlusion, 12 occlusions, 20 unclear cause of small distal ICA on CTA and one excluded. For separation of near-occlusion and conventional stenoses, ICA flow rate and ICA-CBF ratio had the highest area under the curve (AUC; 0.98–0.99) for near-occlusion. ICA-CBF ratio ⩽0.225 was 90% (45/49) sensitive and 99% (188/190) specific for near-occlusion. Inter-rater reliability for this threshold was excellent (kappa 0.98). Specificity was 94% (29/31) for cases with ⩾70% stenosis. PC-MRI had modest performance for separating <50% and conventional ⩾50% stenosis (highest AUC 0.74), and eight (16%) of near-occlusions were not distinguishable from occlusion (no visible flow). Conclusion: ICA-CBF ratio ⩽0.225 on PC-MRI is an accurate and reliable method to separate conventional ⩾50% stenosis and near-occlusion that is feasible for routine use. PC-MRI should be considered further as a potential standard method for near-occlusion detection, to be used side-by-side with established modalities as PC-MRI cannot separate other degrees of stenosis.
