Abstract
AIMS Carotid intima-media thickness (IMT) measurement is used to assess subclinical atherosclerosis. We aimed to examine the association between the maximum IMT by location and the occurrence of silent brain infarction (SBI). METHODS Overall, 280 Japanese individuals (92 females, 52.6±5 years old) underwent a medical check-up at our hospital in Tokyo in 2015. Carotid IMT was measured at each site on ultrasound images (common carotid artery [CCA], internal carotid artery, or bifurcation). The risk factors for arterial dysfunction were evaluated. SBI was assessed using magnetic resonance imaging (MRI). The cross-sectional relationship between carotid maximum IMT and SBI was evaluated. RESULTS Of the 280 individuals, 18 (6.4%) were diagnosed with SBI on MRI. The mean age of the SBI(-) and SBI(+) groups was 51.9±10.6 and 63.6±18.6 years, respectively. The correlation coefficients between the carotid maximum IMT at each location were very weak (correlation coefficient range: 0.180-0.253). The percentage of participants with SBI increased significantly with increasing maximum CCA and bIMT values. After adjusting for confounders, SBI was found to be significantly associated with the maximum bIMT (per 0.1-mm increase) (adjusted odds ratio [aOR], 1.10; 95% confidence interval [CI]: 1.03-1.17). When bIMT was categorized according to three groups (<1.0 mm, 1.0-<2.0 mm, and ≥ 2.0 mm), a significant SBI risk was also observed with an increase by each category of bIMT (aOR: 3.96, 95% CI: 1.63-9.52, P=0.002). CONCLUSION The maximum bIMT was found to be the main determinant of SBI. A significant SBI risk was associated with an increase in each category of the maximum bIMT. Therefore, the maximum bIMT might be a useful predictor of future stroke in Japanese stroke-free medical check-up participants.

Abstract
BACKGROUND Frailty in older individuals is an underappreciated condition that affects the incidence and/or prognosis of stroke. OBJECTIVES We evaluated the prevalence of pre-onset frailty in patients with acute first-onset and recurrent strokes and association between pre-onset frailty and functional disability at hospital discharge. METHODS This prospective cohort study included 210 acute stroke patients admitted to the Stroke Unit of Nippon Medical School Hospital during November 2021-June 2022. The mean participant age was 79.2 ± 7.4 years. Age, sex, pre-onset frailty, body mass index (BMI), stroke type, medical history, and National Institutes of Health Stroke Scale (NIHSS) score at admission were evaluated. Frailty was defined as a clinical frailty scale (CFS) score ≥ 5. Frailty prevalence was calculated for all patients, and scores of functional disabilities at discharge were evaluated using modified Rankin scale. RESULTS Overall frailty prevalence was 31% in all stroke patients, with 24% and 47% of first-onset and recurrent strokes, respectively. Pre-onset frailty, NIHSS score at admission, age, stroke type, previous stroke, sex, BMI, dyslipidemia, and atrial fibrillation were significantly associated with functional disability at discharge. Logistic regression analysis revealed that CFS score, NIHSS score at admission, and previous stroke were independent predictors of functional disability at discharge. CONCLUSIONS Approximately one-fourth of patients with first-onset stroke had pre-onset frailty; the rate doubled in recurrent stroke; these rates appear to be much larger than rate in healthy individuals. Pre-onset frailty, a negative independent factor affecting functional disability at discharge, is important for pre-onset frailty evaluation and rehabilitation intervention in acute stroke patients.

Abstract
AIMS Andexanet alfa, a specific antidote to factor Xa (FXa) inhibitors, has been approved for clinical use in several countries, including Japan, based on the results from the phase 3 trial ANNEXA-4. We aimed to assess the efficacy and safety of andexanet alfa treatment in FXa inhibitor-related acute major bleeding in patients enrolled for ANNEXA-4 in Japan. METHODS This prespecified analysis included patients enrolled at Japanese sites in the prospective, open-label, single-arm ANNEXA-4 trial. Eligible patients had major bleeding within 18 hours of oral FXa inhibitor administration. The coprimary efficacy endpoints were percent change in anti-FXa activity and proportion of patients achieving excellent or good hemostatic efficacy 12 hours post-treatment. RESULTS A total of 19 patients were enrolled, all of whom had intracranial hemorrhage; 16 patients were evaluable for efficacy. Median percent reduction in anti-FXa activity from baseline to nadir was 95.4% in patients taking apixaban, 96.1% in patients taking rivaroxaban, and 82.2% in patients taking edoxaban. Overall, 14/16 patients (88%) achieved excellent or good hemostasis (apixaban, 5/5; rivaroxaban, 6/7; edoxaban, 3/4). Within 30 days, treatment-related adverse events (AEs) and serious AEs occurred in 2 and 5 patients, respectively. One patient died during follow-up, and 2 patients experienced thrombotic events. CONCLUSION Treatment with andexanet alfa rapidly reduced anti-FXa activity with favorable hemostatic efficacy in Japanese patients with acute major bleeding. Serious AEs of thrombotic events during rapid reversal of anti-FXa activity arose as particular safety concerns in this population as with previous studies.

Abstract
AIMS To examine the effect of deprescribing psychotropic medications on activities of daily living (ADLs) and swallowing function in patients undergoing convalescent rehabilitation following a stroke. METHODS In this retrospective cohort study, patients who underwent convalescent rehabilitation after a stroke were divided into two groups: deprescribing (number of psychotropic medications decreased during hospitalization) and non-deprescribing (number of psychotropic medications increased or remained unchanged). The primary outcome measure was ADLs assessed using the Functional Independence-Measured Motor Activity (FIM-motor) score at discharge. A multiple linear regression analysis was conducted to determine the independent association between deprescribing psychotropic medications and rehabilitation outcomes. RESULTS Of the 586 patients enrolled, 128 with a mean age of 74.1 ± 12.7 years were included in the final analysis after being prescribed psychotropic medications, with 36 of them (28.1%) in the deprescribing group. Multiple linear regression analysis revealed that deprescribing psychotropic medications was independently associated with FIM-motor function at discharge. CONCLUSIONS Deprescribing psychotropic medications is positively associated with improvements in ADLs among patients undergoing convalescent rehabilitation after a stroke.

Abstract
OBJECTIVES We aimed to clarify the incidence, clinical profile, outcome, and activities of daily living of patients with stroke using the Kitakyushu clinical pathway database and to investigate the characteristics of patients with stroke in the Kitakyushu medical area in Japan. MATERIALS AND METHODS The clinical data of patients with stroke registered in the Kitakyushu database between April 1, 2009 and December 31, 2021 were retrospectively examined. The National Institutes of Health Stroke Scale was used to classify stroke severity. A descriptive analysis of basic variables, including age, stroke type, length of hospital stay, and activities of daily living, according to stroke severity was conducted. RESULTS There were 7,487 acute care hospital patients and 5,441 rehabilitation hospital patients. Compared with patients in similar cities in Japan, patients in the Kitakyushu area tended to be older at the time of stroke onset with a higher proportion of cases of hemorrhagic stroke. Length of hospital stay in both acute and rehabilitation hospitals increased with stroke severity. The Functional Independence Measure gain was highest in patients with moderate disability. CONCLUSIONS Compared with patients in similar cities in Japan, in the Kitakyushu area, patients with stroke were older and the proportion of patients with hemorrhagic stroke was higher. Stroke rehabilitation therapy is effective for patients with moderately severe stroke.

Abstract
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.

Changes of cortico-cortical neural connections associated with motor functional recovery after stroke. J Stroke Cerebrovasc Dis 2022; 31:106689. [PMID: 35932539 DOI: 10.1016/j.jstrokecerebrovasdis.2022.106689] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 07/21/2022] [Accepted: 07/26/2022] [Indexed: 11/24/2022] Open
Abstract
OBJECTIVES During functional recovery after stroke, some neural connections in the brain are augmented and new neural networks are constructed to compensate for impaired neurological functions. Recently, it was reported that the extent of cortico-cortical neural connections can be estimated by correlation analysis based on electroencephalography (EEG). The purpose of this study was to investigate changes of correlation coefficients in the cerebral cortex with motor functional recovery after stroke. MATERIALS AND METHODS Twenty-two post-stroke hemiparetic patients admitted to our rehabilitation ward (mean age at admission: 71.4 ± 12.9 years old), were studied. For the evaluation of hemiparesis, Fugl-Meyer Assessment (FMA) was applied. All subjects underwent EEG with electrodes placed according to the international 10-20 system for correlation analysis, on admission to our ward and 4 weeks after admission. EEG data were analyzed with the program software FOCUS (NIHON KOHDEN, Japan), and squared correlation coefficients in some cortico-cortical areas of the cerebral cortex were calculated. RESULTS The correlation coefficients in some cortico-cortical areas of the lesional hemisphere, such as C3-F3 or C4-F4, C3-F7 or C4-F8, and F3-F7 or F4-F8, significantly increased with rehabilitation training. The change of the correlation coefficient in F3-F7 or F4-F8 and F7-T3 or F8-T4 in the lesional hemisphere was significantly correlated with the change of the upper-limb FMA. CONCLUSIONS The augmentation of cortico-cortical connections, represented by an increase of the correlation coefficient in the lesional hemisphere, may contribute to motor functional recovery, especially in hemiparetic upper limbs, after stroke.

Abstract
BACKGROUND The spread of COVID-19 has affected stroke rehabilitation. Given that inpatient visits are restricted in most institutions, alternative ways of providing information to family members are imperative. Informing families about patients' rehabilitation progress via the Internet may help involve families in the rehabilitation process, enhance patients' motivation to continue rehabilitation, and contribute overall to patients' improvement in activities of daily living (ADL). OBJECTIVE We aimed to investigate the feasibility of an Internet-based rehabilitation information sharing (IRIS) intervention for families of stroke patients at a rehabilitation hospital and to examine the effect of IRIS on patients' ADL improvement. METHODS In this case-control study, participants were inpatients at a rehabilitation hospital between March 2020 and April 2021. The intervention group (ICT group) included patients and families who requested IRIS, which consisted of a progress report on patients' rehabilitation using text, photos, and movies. Those who did not receive Internet-based information were included in the non-ICT group. The control group, matched with the ICT group based on a 1:1 propensity score, was selected from the non-ICT group. The covariates for calculating the propensity score were patients' age, sex, and motor and cognitive scores on the Functional Independence Measure (FIM) at admission. The main outcome was the degree of ADL improvement during hospitalization. Multiple regression analysis (forced entry method) was performed to confirm the impact of ICT use on ADL improvement. The independent variables were the presence of intervention, length of hospital stay, and the number of days from onset to hospitalization. RESULTS Sixteen groups of patients and families participated in the IRIS. The mean age of patients was 78.6±7.2 and 78.6±8.2 years in the ICT and control groups, respectively. The median total FIM difference was 28.5 (interquartile range 20.3-53.0) and 11.0 (2.8-30.0) in the ICT and control groups, respectively, and the ICT group showed significant improvement in ADL function (p=.02). In the multiple regression analysis of the ICT and control groups, the unstandardized regression coefficients and 95% confidence intervals were 11.97 (0.09 to 23.84) for ICT use. These results indicate that ICT use was independently and significantly associated with improvement in ADL. CONCLUSIONS This study examined the effect of IRIS on family members to improve ADL in hospitalized stroke patients. The results showed that IRIS promotes improvement of patients' ADL regardless of age, sex, and motor and cognitive functions at admission, and length of hospital stay.

Abstract
Background Remote ischemic conditioning (RIC) refers to the application of repeated short periods of ischemia intended to protect remote areas against tissue damage during and after prolonged ischemia. Aim We aim to evaluate the efficacy of RIC, determined by the modified Rankin Scale (mRS) score at 90 days after stroke onset. Design and methods This study is an investigator-initiated, multicenter, prospective, randomized, open-label, parallel-group clinical trial. The sample size is 400, comprising 200 patients who will receive RIC and 200 controls. The patients will be divided into three groups according to their National Institutes of Health Stroke Scale score at enrollment: 5–9, mild; 10–14, moderate; 15–20, severe. The RIC protocol will be comprised of four cycles, each consisting of 5 min of blood pressure cuff inflation (at 200 mmHg or 50 mmHg above the systolic blood pressure) followed by 5 min of reperfusion, with the cuff placed on the thigh on the unaffected side. The control group will only undergo blood pressure measurements before and after the intervention period. This trial is registered with the UMIN Clinical Trial Registry (https://www.umin.ac.jp/: UMIN000046225). Study outcome The primary outcome will be a good functional outcome as determined by the mRS score at 90 days after stroke onset, with a target mRS score of 0–1 in the mild group, 0–2 in the moderate group, and 0–3 in the severe group. Discussion This trial may help determine whether RIC should be recommended as a routine clinical strategy for patients with ischemic stroke.

Abstract
Background Intracerebral hemorrhage (ICH) and acute ischemic stroke (AIS) have common vascular risk factors; however, ICH often occurs in adults aged < 70 years. Intracerebral hemorrhage and AIS in adults aged < 70 years should be preventable; however, it is unclear why different subtypes of ICH or AIS occur among adults aged < 70 years with vascular risk factors. This study aimed to identify independent variables for ICH or AIS onset in patients aged < 70 years. Methods We included patients aged 40–69 years who experienced ICH or AIS between August 2016 and July 2019. Patients aged < 40 years were excluded because other diseases, rather than vascular risk factors, are often associated with stroke etiology in this age group. Data on age, systolic blood pressure (SBP), serum lipids, and serum fatty acid levels were compared between patients with ICH and those with AIS. In addition, we conducted multivariable logistic regression analyses to identify independent factors among the variables, such as blood pressure or biomarkers, with significant differences between the two groups. Results Of the 1252 acute stroke patients screened, 74 patients with ICH and 149 patients with AIS met the inclusion criteria. After excluding variables with multicollinearity, SBP, glycated hemoglobin (HbA1c), and eicosapentaenoic acid (EPA) proportion (%) of total fatty acids were identified as independent factors affecting ICH and AIS. The SBP and EPA% threshold values for ICH compared to AIS were ≥ 158 mmHg and ≤ 2.3%, respectively. The HbA1c threshold value for AIS compared to ICH was ≥ 6.1%. Conclusions Systolic blood pressure, HbA1c, and EPA%, were independent factors between ICH and AIS. Patients aged 40–69 years with high SBP and low EPA% were at a higher risk of ICH than AIS, and those with a high HbA1c were at a higher risk of AIS than ICH.

Association of Timing for Starting Dual Antiplatelet Treatment With Cilostazol and Recurrent Stroke: A CSPS.com Trial Post Hoc Analysis. Neurology 2022; 98:e983-e992. [PMID: 35074890 PMCID: PMC8967394 DOI: 10.1212/wnl.0000000000200064] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 12/27/2021] [Indexed: 11/17/2022] Open
Abstract
Background and Objectives Long-term treatment with the combination of cilostazol with aspirin or clopidogrel showed a lower risk of stroke recurrence compared to aspirin or clopidogrel alone after high-risk noncardioembolic ischemic stroke in a randomized trial. We aimed to determine whether the effect of the dual medication compared to monotherapy on risk of recurrent ischemic stroke differs according to timing of starting medication after stroke onset. Methods In a subanalysis of the randomized controlled trial, patients between 8 and 180 days after stroke onset were randomly assigned to receive aspirin or clopidogrel alone or a combination of cilostazol with aspirin or clopidogrel. They were divided into 3 groups according to the timing of starting trial treatment: between 8 and 14 days after stroke onset (8–14 days group), between 15 and 28 days after stroke onset (15–28 days group), and between 29 and 180 days after stroke onset (29–180 days group). The primary efficacy outcome was the first recurrence of ischemic stroke. Safety outcomes included severe or life-threatening bleeding. Results Of 1,879 patients, 498 belonged to the 8–14 days group, 467 to the 15–28 days group, and 914 to the 29–180 days group. There was a significant treatment-by-subgroup interaction for the recurrence of ischemic stroke between trial treatment and trichotomized groups. The recurrence of ischemic stroke was less common with dual therapy than with monotherapy in the 15–28 days group (annualized rate 1.5% vs 4.9%, respectively; adjusted hazard ratio 0.34 [95% CI 0.12–0.95]) and the 29–180 days group (1.9% vs 4.4%, respectively; 0.27 [0.12–0.63]) and similarly common in the 8–14 days group (4.5% for both; 1.02 [0.51–2.04]). Severe or life-threatening bleeding occurred similarly between patients on dual therapy and those on monotherapy in any of the trichotomized groups (crude hazard ratio 0.22 [95% CI 0.03–1.88] in the 8–14 days group, 1.07 [0.15–7.60] in the 15–28 days group, and 0.76 [0.24–2.39] in the 29–180 days group). Discussion Long-term dual antiplatelet therapy using cilostazol starting 15–180 days after stroke onset, compared to therapy started 8–14 days after onset, was more effective for secondary stroke prevention than monotherapy without increasing hemorrhage risk. Trial Registration Information ClinicalTrials.gov NCT01995370; UMIN Clinical Trials Registry 000012180. Classification of Evidence This study provides Class II evidence that for patients with acute noncardioembolic stroke taking either aspirin or clopidogrel, the addition of cilostazol 15–180 days after stroke onset decreases the risk of recurrent ischemic stroke.

Abstract
Question Did the initial neurological severity and functional outcomes of patients with stroke change throughout a 20-year period? Findings In this hospital-based, multicenter, prospective registry involving 183 080 patients with acute stroke, initial neurological severity showed a decrease over time in all stroke types. Functional outcome at hospital discharge improved in patients with ischemic stroke but no longer showed improvement after adjustment by reperfusion therapy and others; it did not clearly improve in patients with hemorrhagic stroke. Meaning Twenty-year changes in functional outcomes after ischemic and hemorrhagic strokes showed different trends presumably partly owing to differences in the development of acute therapeutic strategies. Importance Whether recent changes in demographic characteristics and therapeutic technologies have altered stroke outcomes remains unknown. Objective To determine secular changes in initial neurological severity and short-term functional outcomes of patients with acute stroke by sex using a large population. Design, Setting, and Participants This nationwide, hospital-based, multicenter, prospective registry cohort study used the Japan Stroke Data Bank and included patients who developed acute stroke from January 2000 through December 2019. Patients with stroke, including ischemic and hemorrhagic strokes, who registered within 7 days after symptom onset were studied. Modified Rankin Scale scores were assessed at hospital discharge for all patients. Exposure Time. Main Outcomes and Measures Initial severity was assessed by the National Institutes of Health Stroke Scale for ischemic stroke and intracerebral hemorrhage and by the World Federation of Neurological Surgeons grading for subarachnoid hemorrhage. Outcomes were judged as favorable if the modified Rankin Scale score was 0 to 2 and unfavorable if 5 to 6. Results Of 183 080 patients, 135 266 (53 800 women [39.8%]; median [IQR] age, 74 [66-82] years) developed ischemic stroke, 36 014 (15 365 women [42.7%]; median [IQR] age, 70 [59-79] years) developed intracerebral hemorrhage, and 11 800 (7924 women [67.2%]; median [IQR] age, 64 [53-75] years) developed subarachnoid hemorrhage. In all 3 stroke types, median ages at onset increased, and the National Institutes of Health Stroke Scale and World Federation of Neurological Surgeons scores decreased throughout the 20-year period on multivariable analysis. In ischemic stroke, the proportion of favorable outcomes showed an increase over time after age adjustment (odds ratio [OR], 1.020; 95% CI, 1.015-1.024 for women vs OR, 1.015; 95% CI, 1.011-1.018 for men) but then stagnated, or even decreased in men, on multivariate adjustment including reperfusion therapy (OR, 0.997; 95% CI, 0.991-1.003 for women vs OR, 0.990; 95% CI, 0.985-0.994 for men). Unfavorable outcomes and in-hospital deaths decreased in both sexes. In intracerebral hemorrhage, favorable outcomes decreased in both sexes, and unfavorable outcomes and deaths decreased only in women. In subarachnoid hemorrhage, the proportion of favorable outcomes was unchanged, and that of unfavorable outcomes and deaths decreased in both sexes. Conclusions and Relevance In this study, functional outcomes improved in patients with ischemic stroke during the past 20 years in both sexes presumably partly owing to the development of acute reperfusion therapy. The outcomes of patients with hemorrhagic stroke did not clearly improve in the same period.

Abstract
Cilostazol is a PDE3 (phosphodiesterase III) inhibitor with a long track record of safety that is Food and Drug Administration and European Medicines Agency approved for the treatment of claudication in patients with peripheral arterial disease. In addition, cilostazol has been approved for secondary stroke prevention in several Asian countries based on trials that have demonstrated a reduction in stroke recurrence among patients with noncardioembolic stroke. The onset of benefit appears after 60 to 90 days of treatment, which is consistent with cilostazol's pleiotropic effects on platelet aggregation, vascular remodeling, blood flow, and plasma lipids. Cilostazol appears safe and does not increase the risk of major bleeding when given alone or in combination with aspirin or clopidogrel. Adverse effects such as headache, gastrointestinal symptoms, and palpitations, however, contributed to a 6% increase in drug discontinuation among patients randomized to cilostazol in a large secondary stroke prevention trial (CSPS.com [Cilostazol Stroke Prevention Study for Antiplatelet Combination]). Due to limitations of prior trials, such as open-label design, premature trial termination, large loss to follow-up, lack of functional or cognitive outcome data, and exclusive enrollment in Asia, the existing trials have not led to a change in clinical practice or guidelines in Western countries. These limitations could be addressed by a double-blind placebo-controlled randomized trial conducted in a broader population. If positive, it would increase the evidence in support of long-term treatment with cilostazol for secondary prevention in the millions of patients worldwide who have experienced a noncardioembolic ischemic stroke.

Abstract
Aims The bleeding risk of current antithrombotic strategies in clinical settings, including recently developed agents, needs to be clarified. Methods and Design In an investigator-initiated, prospective, multicentre, observational study, patients with cerebrovascular or cardiovascular diseases who were taking oral antiplatelet or anticoagulant agents were enrolled. Compulsory multimodal magnetic resonance images were acquired at baseline to assess cerebral small vessel disease. Six-month follow-up will be performed for two years. The primary outcome is major bleeding as defined by the International Society on Thrombosis and Hemostasis. Results Between October 2016 and March 2019, 5306 patients (71.7 ± 11.2 years old, 1762 women) were enrolled. Previous intracranial haemorrhage was documented in 181 patients (3.4%), cerebrovascular disease (including asymptomatic) requiring antithrombotic therapy in 5006 patients (94.3%), and atrial fibrillation in 1061 patients (20.0%). At entry, 3726 patients (70.2%) were taking antiplatelet agents alone, including 551 (10.4%) using dual antiplatelet agents, 1317 (24.8%) taking anticoagulants alone, and the remaining 263 (5.0%) taking both. The leading antiplatelet agent was clopidogrel (2014 patients), and the leading combination of dual antiplatelet medication was clopidogrel plus aspirin (362). Use of direct oral anticoagulants (1029 patients, 19.4%) exceeded warfarin use (554, 10.4%). The number of pivotal bleeding events exceeded 200 in April 2020. Conclusions This study is expected to provide the incidence of bleeding complications of recent oral antithrombotics in clinical practice and identify their associations with underlying small vessel disease and other biomarkers. Novel risk stratification models for bleeding risk will be able to be created based on the study results.

Abstract
Background Stroke is one of the leading causes of death worldwide. Cilostazol, an antiplatelet and phosphodiesterase 3 inhibitor, has not been clearly established for ischaemic stroke use. We aim to determine the efficacy and safety of cilostazol for secondary stroke prevention. Methods MEDLINE, EMBASE, Cochrane Library, Web of Science and ClinicalTrials.gov were searched from inception to 25 September 2020, for randomised trials comparing the efficacy and safety of cilostazol monotherapy or dual therapy with another antiplatelet regimen or placebo, in patients with ischaemic stroke. Version 2 of the Cochrane risk-of-bias tool for randomised trials (RoB 2) was used to assess study quality. This meta-analysis was reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results Eighteen randomised trials comprising 11 429 participants were included in this meta-analysis. Most trials possessed low risk of bias and were of low heterogeneity. Cilostazol significantly reduced the rate of ischaemic stroke recurrence (risk ratio, RR=0.69, 95% CI 0.58 to 0.81), any stroke recurrence (RR=0.64, 95% CI 0.54 to 0.74) and major adverse cardiovascular events (RR=0.67, 95% CI 0.56 to 0.81). Cilostazol did not significantly decrease mortality (RR=0.90, 95% CI 0.64 to 1.25) or increase the rate of good functional outcome (Modified Rankin Scale score of 0–1; RR=1.07, 95% CI 0.95 to 1.19). Cilostazol demonstrated favourable safety profile, significantly reducing the risk of intracranial haemorrhage (RR=0.46, 95% CI 0.31 to 0.68) and major haemorrhagic events (RR=0.49, 95% CI 0.34 to 0.70). Conclusions Cilostazol demonstrated superior efficacy and safety profiles compared with traditional antiplatelet regimens such as aspirin and clopidogrel for secondary stroke prevention but does not appear to affect functional outcomes. Future randomised trials can be conducted outside East Asia, or compare cilostazol with a wider range of antiplatelet agents.

Current status of a helicopter transportation system on remote islands for patients undergoing mechanical thrombectomy. PLoS One 2021; 16:e0245082. [PMID: 33465116 PMCID: PMC7815141 DOI: 10.1371/journal.pone.0245082] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 12/21/2020] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Mechanical thrombectomy (MT) is standard treatment for acute ischemic stroke (AIS) with large-vessel occlusion within 6 h of symptom onset to treatment initiation (OTP). Recent trials have extended the therapeutic time window for MT to within 24 h. However, MT treatment remains low in remote areas. Nagasaki Prefecture, Japan has many inhabited islands with no neurointerventionalists. Our hospital on the mainland is a regional hub for eight island hospitals. We evaluated clinical outcomes of MT for patients with AIS on these islands versus on the mainland. METHODS During 2014-2019, we reviewed consecutive patients with AIS who received MT at our hospital. Patients comprised the Islands group and Mainland group. Patient characteristics and clinical outcomes were compared between groups. RESULTS We included 91 patients (Islands group: 15 patients, Mainland group: 76 patients). Seven patients (46.7%) in the Islands group versus 43 (56.6%) in the Mainland group achieved favorable outcomes. Successful recanalization was obtained in 11 patients (73.3%) on the islands and 67 (88.2%) on the mainland. The median OTP time in the Islands was 365 min. In both the Islands and Mainland groups, the OTP time and successful recanalization were associated with functional outcome. The modified Rankin Scale (mRS) score at 90 days ≤2 was obtained in two patients and mRS = 3 in four patients among eight patients with OTP time >6 h. CONCLUSIONS Few patients with AIS on remote islands have received MT. Although patients who underwent MT on the islands had longer OTP, the clinical outcomes were acceptable. OTP time on remote islands must be shortened, as this is related to functional outcome. In some cases with successful recanalization, a favorable outcome can still be obtained even after 6 h. Even if OTP exceeds 6 h, it is desirable to appropriately select patients and actively perform MT.

Abstract
BACKGROUND AND PURPOSE We determined to identify patients with unknown onset stroke who could have favorable 90-day outcomes after low-dose thrombolysis from the THAWS (Thrombolysis for Acute Wake-Up and Unclear-Onset Strokes With Alteplase at 0.6 mg/kg) database. METHODS This was a subanalysis of an investigator-initiated, multicenter, randomized, open-label, blinded-end point trial. Patients with stroke with a time last-known-well >4.5 hours who showed a mismatch between diffusion-weighted imaging (DWI) and fluid-attenuated inversion recovery were randomly assigned (1:1) to receive alteplase at 0.6 mg/kg intravenously or standard medical treatment. The patients were dichotomized by ischemic core size or National Institutes of Health Stroke Scale score, and the effects of assigned treatments were compared in each group. The efficacy outcome was favorable outcome at 90 days, defined as a modified Rankin Scale score of 0 to 1. RESULTS The median DWI-Alberta Stroke Program Early CT Score (ASPECTS) was 9, and the median ischemic core volume was 2.5 mL. Both favorable outcome (47.1% versus 48.3%) and any intracranial hemorrhage (26% versus 14%) at 22 to 36 hours were comparable between the 68 thrombolyzed patients and the 58 control patients. There was a significant treatment-by-cohort interaction for favorable outcome between dichotomized patients by ASPECTS on DWI (P=0.026) and core volume (P=0.035). Favorable outcome was more common in the alteplase group than in the control group in patients with DWI-ASPECTS 5 to 8 (RR, 4.75 [95% CI, 1.33-30.2]), although not in patients with DWI-ASPECTS 9 to 10. Favorable outcome tended to be more common in the alteplase group than in the control group in patients with core volume >6.4 mL (RR, 6.15 [95% CI, 0.87-43.64]), although not in patients with volume ≤6.4 mL. The frequency of any intracranial hemorrhage did not differ significantly between the 2 treatment groups in any dichotomized patients. CONCLUSIONS Patients developing unknown onset stroke with DWI-ASPECTS 5 to 8 showed favorable outcomes more commonly after low-dose thrombolysis than after standard treatment.

Abstract
Objective To compare the impact of intensive blood pressure (BP) lowering right after intracerebral hemorrhage (ICH) on clinical and hematoma outcomes among patients from different geographic locations, we performed a prespecified subanalysis of a randomized, multinational, 2-group, open-label trial to determine the efficacy of rapidly lowering BP in hyperacute ICH (Antihypertensive Treatment of Acute Cerebral Hemorrhage [ATACH]-2), involving 537 patients from East Asia and 463 recruited outside of Asia. Methods Eligible patients were randomly assigned to a systolic BP target of 110 to 139 mm Hg (intensive treatment) or 140 to 179 mm Hg (standard treatment). Predefined outcomes were poor functional outcome (modified Rankin Scale score 4–6 at 90 days), death within 90 days, hematoma expansion at 24 hours, and cardiorenal adverse events within 7 days. Results Poor functional outcomes (32.0% vs 45.9%), death (1.9% vs 13.3%), and cardiorenal adverse events (3.9% vs 11.2%) occurred significantly less frequently in patients from Asia than those outside of Asia. The treatment-by-cohort interaction was not significant for any outcomes. Only patients from Asia showed a lower incidence of hematoma expansion with intensive treatment (adjusted relative risk [RR] 0.56, 95% confidence interval [CI] 0.38–0.83). Both Asian (RR 3.53, 95% CI 1.28–9.64) and non-Asian (RR 1.71, 95% CI 1.00–2.93) cohorts showed a higher incidence of cardiorenal adverse events with intensive treatment. Conclusions Poor functional outcomes and death 90 days after ICH were less common in patients from East Asia than those outside of Asia. Hematoma expansion, a potential predictor for poor clinical outcome, was attenuated by intensive BP lowering only in the Asian cohort. ClinicalTrials.gov Identifier NCT01176565. Classification of Evidence This study provides Class II evidence that, for patients from East Asia with ICH, intensive blood pressure lowering significantly reduces the risk of hematoma expansion.

The dawning of the digital era in the management of hypertension. Hypertens Res 2020; 43:1135-1140. [PMID: 32655134 DOI: 10.1038/s41440-020-0506-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2020] [Revised: 05/31/2020] [Accepted: 06/03/2020] [Indexed: 12/12/2022]
Abstract
Awareness, treatment, and control of hypertension are of the utmost importance in conquering stroke and cardiovascular disease. To reduce the global burden of hypertension, the Japanese Society of Hypertension (JSH) established the "JSH Future Plan" based on an increasing need to transform the strategy for combating hypertension. In addition to energizing conventional approaches in basic, translational, and clinical research, the application of rapidly evolving digital health technologies and artificial intelligence to hypertension healthcare and research (digital hypertension) holds promise for providing further insights into the pathophysiology and therapeutic targets and implementing predictive, personalized, and preemptive approaches in clinical practice. With great potential to revolutionize the landscape of hypertension, digital hypertension has some technical, legal, ethical, social, and financial issues to overcome. Given the multidisciplinary framework, digital hypertension requires comprehensive and strategic collaboration among industry, academia, and government to move forward toward the goal of "Future Medicine".

Abstract
BACKGROUND Stroke is one of the major causes of maternal death. This study aimed to analyze the maternal and fetal outcomes of stroke occurred during pregnancy and puerperium. METHODS We conducted a retrospective analysis of patients admitted to our perinatology center between 1982 and 2012 with a diagnosis of acute cerebral stroke during pregnancy or within 6 weeks postpartum. RESULTS Thirty-four patients were registered and all the patients had never been diagnosed as stroke nor detected cerebrovascular abnormalities before the current pregnancies. They were divided into 8 ischemic strokes (ISs) and 26 intracranial hemorrhage group. In the hemorrhage group, there was a spontaneous abortion and two patients chose artificial abortions to avoid rehemorrhage, and there were another three intrauterine fetal deaths (IUFDs) in the acute stage of maternal stroke. More patients in hemorrhage group delivered in preterm than in IS group for the treatment of stroke, 10/23 (43%) versus 0/8 (0%), p < .05. More patients in hemorrhage group had low Glasgow Coma Scale (GCS) (3-8) than in IS group at the onset of the stroke, 12/26 (46%) versus 0/8 (0%), p < .05. There were three maternal deaths and 6/23 (26%) were neurologically dependent in hemorrhage group in the chronic stage, whereas 87% were independent in IS group, p < .05. CONCLUSIONS Hemorrhagic stroke was more common etiology of stroke related to pregnancy than IS in this study. Intensive and multidisciplinary care was needed especially in hemorrhagic stroke related to pregnancy as in the hemorrhagic stroke the fetal survival rate was lower, and maternal conscious levels at the onset of the stroke and neurological outcomes in the chronic stage were worse than IS.
