Background and objectives: Cancer is associated with an increased risk of acute ischemic stroke (AIS) and venous thromboembolism. The role of a cardiac right-to-left shunt (RLS) as a surrogate parameter for paradoxical embolism in cancer-related strokes is uncertain. We sought to investigate the relationship between the presence of an RLS and cancer in AIS patients.
Methods: We included consecutive AIS patients hospitalized at our tertiary stroke center between January 2015 and December 2020 with available RLS status as detected on transesophageal echocardiography (TEE). Active cancers were retrospectively identified and the association with RLS was assessed with multivariable logistic regression and inverse probability of treatment weighting to minimize the ascertainment bias of having a TEE obtained.
Results: Of the 2236 AIS patients included, 103 (4.6%) had active cancer, of whom 24 (23%) were diagnosed with RLS. An RLS was present in 774 out of the 2133 AIS patients without active cancer (36%). After adjustment and weighting, the absence of RLS was associated with active cancer (adjusted odds ratio (aOR) 2.29; 95% confidence interval (CI), 1.14-4.58). When analysis was restricted to patients younger than 60 years of age or those with a high-risk RLS (Risk of Paradoxical Embolism Score ⩾ 6), there was no association between RLS and cancer (aOR, 3.07; 95% CI, 0.79-11.88 and aOR, 0.56; 95% CI, 0.10-3.10, respectively).
Conclusion: RLS was diagnosed less frequently in AIS patients with cancer than in cancer-free patients, suggesting that arterial sources may play a larger role in cancer-related strokes than paradoxical venous embolization. Future studies are needed to validate these findings and evaluate potential therapeutic implications, such as the general indication, or lack thereof, for patent foramen ovale (PFO) closure in this patient population.

Background: Endovascular thrombectomy (EVT) and intravenous thrombolysis (IVT) have an unclear benefit in those with pre-stroke dementia or cognitive impairment, as these patients were often excluded from landmark stroke trials. We performed a systematic review and meta-analysis to assess the outcomes of IVT and EVT in these populations.
Aims: Our systematic review, conforming to the Meta-Analysis of Observational Studies in Epidemiology guidelines, investigated studies on acute ischemic stroke patients with pre-stroke dementia or cognitive impairment treated with IVT or EVT. Primary outcome was favorable 90-day outcome (mRS 0-2). Secondary outcomes included 90-day mortality, symptomatic intracranial hemorrhage (SICH), and radiographic intracranial hemorrhage (ICH).
Summary of review: Nine articles were identified, with five observational studies of IVT use in patients with (n = 1078) and without dementia (n = 2805) being selected for the meta-analysis. There were no significant differences in favorable outcome (adjusted OR: 0.61, 95% CI 0.24-1.59), mortality (unadjusted OR: 1.19, 95% CI 0.86-1.64), ICH (unadjusted OR: 1.32, 95% CI 0.79-2.19), and symptomatic ICH (unadjusted OR: 0.94, 95% CI 0.70-1.25) for patients undergoing IVT with pre-stroke dementia versus those without. One EVT study (n = 615 with dementia vs n = 9600 without) found no significant differences in outcomes apart from an increased odds of ICH for those with pre-existing dementia (adjusted OR: 1.57, 95% CI 1.03-2.40). A pooled analysis of three IVT studies showed no significant association of cognitive impairment (n = 93 vs n = 211 without) with all assessed outcomes, whereas a study of EVT found that pre-stroke cognitive impairment was associated with poor 90-day outcomes (mRS 3-6).
Conclusion: These results suggest no substantial safety issues in the use of IVT or EVT for patients with pre-existing dementia or cognitive impairment compared to those without. However, the efficacy of these therapies in this demographic remains uncertain. Further rigorous studies that include a more nuanced outcome measurement approach are warranted.

Background and aim: The revised Boston criteria v2.0 for cerebral amyloid angiopathy (CAA) add two radiological markers to the existing criteria: severe visible perivascular spaces in the centrum semiovale and white matter hyperintensities (WMHs) in a multispot pattern. This study aims to determine the sensitivity of the updated criteria in mutation carriers with Dutch-type hereditary CAA (D-CAA) in an early and later disease stage.
Methods: In this cross-sectional study, we included presymptomatic and symptomatic D-CAA mutation carriers from our prospective natural history study (AURORA) at the Leiden University Medical Center between 2018 and 2021. 3-Tesla scans were assessed for CAA-related magnetic resonance imaging (MRI) markers. We compared the sensitivity of the Boston criteria v2.0 to the previously used modified Boston criteria v1.5.
Results: We included 64 D-CAA mutation carriers (mean age 49 years, 55% women, 55% presymptomatic). At least one white matter (WM) feature was seen in 55/64 mutation carriers (86%: 74% presymptomatic, 100% symptomatic). Fifteen (23%) mutation carriers, all presymptomatic, showed only WM features and no hemorrhagic markers. The sensitivity for probable CAA was similar between the new and the previous criteria: 11/35 (31%) in presymptomatic mutation carriers and 29/29 (100%) in symptomatic mutation carriers. The sensitivity for possible CAA in presymptomatic mutation carriers increased from 0/35 (0%) to 15/35 (43%) with the new criteria.
Conclusion: The Boston criteria v2.0 increase the sensitivity for detecting possible CAA in presymptomatic D-CAA mutation carriers and, therefore, improve the detection of the early phase of CAA.

Background: Heat and heatwave have been associated with stroke morbidity, but it is still unclear whether immigrants from different geographic regions and patients with comorbidity are more vulnerable to heat and heatwave.
Methods: Time-stratified case-crossover design combined with generalized additive quasi-Poisson models were used to quantify the relative risks (RRs) of heat and heatwave on first-ever stroke morbidity during 0-7 lag days. Attributable fractions (AFs) were estimated to assess the first-ever stroke morbidity burden due to heat and heatwave. Stratified analyses for sex, age, disease subtypes, resident characteristics, and comorbidity type were performed to identify potential modification effects.
Results: Heat and heatwave were associated with first-ever stroke morbidity, with the AF of 2.535% (95% empirical confidence interval (eCI) = 0.748, 4.205) and 2.409% (95% confidence interval (CI) = 1.228, 3.400), respectively. Among northern and southern immigrants, the AF for heat was 2.806% (0.031, 5.069) and 2.798% (0.757, 4.428), respectively, and the AF for heatwave was 2.918% (0.561, 4.618) and 2.387% (1.174, 3.398), respectively, but the effects of both on natives were statistically insignificant. Among patients with hypertension, dyslipidemia, or diabetes, the AF for heat was 3.318% (1.225, 5.007), 4.237% (1.037, 6.770), and 4.860% (1.171, 7.827), respectively, and the AF for heatwave was 2.960% (1.701, 3.993), 2.771% (0.704, 4.308), and 2.652% (0.653, 4.185), respectively. However, the effects of both on patients without comorbidity were statistically insignificant.
Conclusion: Heat and heatwave are associated with an increased risk of first-ever stroke morbidity among immigrants and those with comorbid hypertension, dyslipidemia, or diabetes, with the effects primarily due to non-native individuals.

Background and aim: To investigate the prognostic implication of body mass index (BMI) on clinical outcomes after acute ischemic and hemorrhagic stroke.
Methods: The subjects of the study included adult patients with available baseline body weight and height data who had suffered an acute stroke and were registered in the Japan Stroke Data Bank-a hospital-based, multicenter stroke registration database-between January 2006 and December 2020. The outcome measures included unfavorable outcomes defined as a modified Rankin Scale (mRS) score of 5-6 and favorable outcomes (mRS 0-2) at discharge, and in-hospital mortality. Mixed effects logistic regression analysis was conducted to determine the relationship between BMI categories (underweight, normal weight, overweight, class I obesity, class II obesity; <18.5, 18.5-23.0, 23.0-25.0, 25-30, ⩾30 kg/m2) and the outcomes, after adjustment for covariates.
Results: A total of 56,230 patients were assigned to one of the following groups: ischemic stroke (IS, n = 43,668), intracerebral hemorrhage (ICH, n = 9741), and subarachnoid hemorrhage (SAH, n = 2821). In the IS group, being underweight was associated with an increased likelihood of unfavorable outcomes (odds ratio, 1.47 (95% confidence interval (CI):1.31-1.65)) and in-hospital mortality (1.55 (1.31-1.83)) compared to outcomes in those with normal weight. Being overweight was associated with an increased likelihood of favorable outcomes (1.09 (1.01-1.18)). Similar associations were observed between underweight and these outcomes in specific IS subtypes (cardioembolic stroke, large artery stroke, and small-vessel occlusion). Patients with a BMI ⩾30.0 kg/m2 was associated with an increased likelihood of unfavorable outcomes (1.44 (1.01-2.17)) and in-hospital mortality (2.42 (1.26-4.65)) in large artery stroke. In patients with ICH, but not those with SAH, being underweight was associated with an increased likelihood of unfavorable outcomes (1.41 (1.01-1.99)).
Conclusions: BMI substantially impacts functional outcomes following IS and ICH. Lower BMI consistently affected post-stroke disability and mortality, while higher BMI values similarly affected these outcomes after large artery stroke.
背景和目的:研究体重指数(BMI)对急性缺血性和出血性脑卒中临床预后的影响:研究对象包括 2006 年 1 月至 2020 年 12 月期间在日本脑卒中数据库(Japan Stroke Data Bank)--一个基于医院的多中心脑卒中登记数据库--登记的急性脑卒中成年患者,这些患者均有体重和身高基线数据。结果测量包括出院时的不利结果(定义为改良Rankin量表(mRS)5-6分)、有利结果(mRS 0-2)和院内死亡率。在对协变量进行调整后,进行了混合效应逻辑回归分析,以确定体重指数类别(体重不足、正常体重、超重、I 级肥胖、II 级肥胖;2)与结果之间的关系:共有 56230 名患者被分配到以下组别:缺血性中风(IS,n = 43668)、脑内出血(ICH,n = 9741)和蛛网膜下腔出血(SAH,n = 2821)。在IS组中,与体重正常者的结果相比,体重过轻与不利结果(几率比1.47(95%置信区间(CI):1.31-1.65))和院内死亡率(1.55(1.31-1.83))的可能性增加有关。超重与有利结果的可能性增加有关(1.09 (1.01-1.18))。在特定的 IS 亚型(心栓塞性中风、大动脉中风和小血管闭塞)中,也观察到体重不足与这些结果之间存在类似的关联。在大动脉卒中中,BMI ⩾30.0 kg/m2 的患者出现不良预后(1.44 (1.01-2.17))和院内死亡率(2.42 (1.26-4.65))的可能性增加。在 ICH 患者中,体重过轻与不良预后的可能性增加(1.41 (1.01-1.99))相关,但与 SAH 患者无关:结论:体重指数对IS和ICH后的功能预后有很大影响。结论:体重指数对 IS 和 ICH 后的功能预后有很大影响。体重指数越低,中风后的残疾率和死亡率越高,而体重指数越高,大动脉中风后的这些预后也会受到类似影响。

Background: Stroke is a common complication of infective endocarditis (IE). Our aim was to describe the prevalence and prognostic impact of stroke in a national cohort of IE.
Methods: Consecutive inclusion at 46 Spanish hospitals between 2008 and 2021.
Results: Out of 5667 IE cases, 1125 had acute stroke (19.8%): 818 ischemic strokes (811 cardioembolic strokes (193 with hemorrhagic transformation), 4 transient ischemic attacks, 3 lacunar infarctions), 127 intracranial hemorrhages, and 27 other neurological complications (cerebral abscesses, encephalitis, and meningitis). Compared to patients without stroke, those with stroke had a similar mean age (69 years) but were more frequently female (68.2% vs 63.7%, p = 0.04) and had a higher incidence of intracardiac complications (35% vs 30%, p = 0.01), surgical indication (69.9% vs 65.9%, p = 0.001), in-hospital mortality (40.9% vs 22.0%, p < 0.001), and 1-year mortality (46.2% vs 27.9%, p < 0.001). The following variables were independently associated with stroke: mitral location (odds ratio (OR) = 1.5, 95% confidence interval (CI) = 1.34-1.8, p < 0.001), vascular phenomenon (OR = 2.9, 95% CI = 2.4-3.6, p = 0.0001), acute renal failure (OR = 1.2, 95% CI = 1.0-1.4, p = 0.021), septic shock (OR = 1.3, 95% CI = 1.1-1.6, p = 0.007), sepsis (OR = 1.3, 95% CI = 1.1-1.6, p = 0.005), surgery indicated but not performed (OR = 1.4, 95% CI = 1.2-1.7, p < 0.001), community-acquired IE (OR = 1.2, 95% CI = 1-1.4, p = 0.017), and peripheral embolization (OR = 1.6, 95% CI = 1.4-1.9, p < 0.001). Stroke was an independent predictor of in-hospital (OR = 2.1, 95% CI = 1.78-2.51, p < 0.001) and 1-year mortality (hazard ratio = 1.9, 95% CI = 1.6-2.5).
Conclusion: One-fifth of patients with IE have concomitant stroke. Stroke is associated with mortality.

Objective: There is a paucity of studies investigating the outcomes among Asian stroke patients. Identifying subgroups of stroke patients at risk of poorer outcomes could identify patients who would benefit from targeted interventions. Therefore, the aim of this study was to identify which ischemic stroke patients at high risk of recurrent events and mortality.
Methods: This cohort study adhered to STrengthening the Reporting of OBservational studies in Epidemiology (STROBE) guidelines. We obtained data from the Singapore Stroke Registry (SSR) from 2005 to 2016 and cross referenced to the Death Registry and the Myocardial Infarction Registry. Outcome measures included recurrent stroke, acute myocardial infarction (AMI), and all-cause and stroke-related deaths. Multivariable Cox proportional hazards regression models were performed to determine risk factors for recurrent stroke, AMI, and all-cause and stroke-related deaths.
Results: A total of 64,915 patients (6705 young, and 58,210 older) were included in our analysis. Older stroke patients were found to have an increased risk of recurrent stroke (hazard ratio (HR) = 1.21, 95% confidence interval (CI) = 1.12-1.30), AMI (HR = 1.73, 95% CI = 1.54-1.95), all-cause death (HR = 2.49, 95% CI = 2.34-2.64), and stroke-related death (HR = 176, 95% CI = 1.61-1.92). Among young stroke patients, males were at increased risk for recurrent stroke (HR = 1.18, 95% CI = 1.01-1.39) and AMI (HR = 1.41, 95% CI = 1.08-1.83), but at reduced risk for all-cause (HR = 0.78, 95% CI = 0.69-0.89) and stroke-related deaths (HR = 0.79, 95% CI = 0.67-0.94). Ethnicity appeared to influence outcomes, with Malay patients at increased risk of recurrent stroke (HR = 1.37, 95% CI = 1.14-1.65), AMI (HR = 2.45, 95% CI = 1.87-3.22), and all-cause (HR = 1.43, 95% CI = 1.24-1.66) and stroke-related deaths (HR = 1.34, 95% CI = 1.09-1.64). Indian patients were also at increased risk of AMI (HR = 1.96, 95% CI = 1.41-2.72). Similar findings were seen among the older stroke patients.
Conclusion: This study found that older stroke patients are at risk of poorer outcomes. Within the young stroke population specifically, males were predisposed to recurrent stroke and AMI but were protected against all-cause and stroke-related deaths. Males were also at reduced risk of all-cause and stroke-related deaths in the older stroke population. In addition, Malay and Indian patients experience poorer outcomes after first stroke. Further optimization of risk factors targeting these high-priority populations are needed to achieve high-quality care.

Rationale: Early neurological deterioration (END) within 72 h of stroke onset is associated with poor prognosis. Optimizing hydration might reduce the risk of END.
Aims: This study aimed to determine in acute ischemic stroke patients if enhanced hydration versus standard hydration reduced the incidence of major (primary) and minor (secondary) END, as well as whether it increased the incidence of early neurological improvement (secondary), at 72 h after admission.
Sample size estimate: A total of 244 participants per arm.
Methods and design: A prospective, double-blinded, multicenter, parallel-group, randomized controlled trial conducted at four hospitals from April 2014 to July 2020, with data analyzed in August 2020. The sample size estimated was 488 participants (244 per arm). Ischemic stroke patients with measurable neurological deficits of onset within 12 h of emergency department presentation and blood urea nitrogen/creatinine (BUN/Cr) ratio ⩾ 15 at point of admission were enrolled and randomized to 0.9% sodium chloride infusions of varying rates-enhanced hydration (20 mL/kg body weight, one-third given via bolus and remainder over 8 h) versus standard hydration (60 mL/h for 8 h), followed by maintenance infusion of 40-80 mL/h for the subsequent 64 h. The primary outcome measure was the incidence of major END at 72 h after admission, defined as an increase in National Institutes of Health Stroke Scale of ⩾ 4 points from baseline.
Results: Overall, 487 participants were randomized (median age 67 years; 287 females). At 72 h, 7 (2.9%) in the enhanced hydration arm and 5 (2.0%) in the standard hydration developed major END (p = 0.54). The incidence of minor END and early neurological improvement did not differ between treatment arms.
Conclusion and relevance: Enhanced hydration did not reduce END or improve short-term outcomes in acute ischemic stroke.

Background: Impactful, evidence-based solutions in surveillance, prevention, acute care, and rehabilitation for stroke survivors are required to address the high global burden of stroke. Patient and public involvement (PPI), where patients, their families, and the public are actively involved as research partners, enhances the relevance, credibility, and impact of stroke-related research.
Aims: This scoping review, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) Scoping Review guidelines, aims to identify and summarize how PPI is currently implemented and reported in empirical stroke research using a participatory approach.
Summary of review: A comprehensive search strategy was developed and implemented across Medline, CINAHL, EMBASE, PsynchINFO, and Cochrane electronic databases, supplemented by gray literature searches. Empirical stroke research articles in the English language, published from 2014 up to 2023, and documenting PPI activity were included. Of the 18,143 original articles identified, 2824 full-text manuscripts matching from this time window were screened. Only 2% (n = 72) of these directly reported embedded PPI activity in empirical research. The majority were qualitative in design (60%) and conducted in high-income countries (96%). Only one included study originated from a developing country, where the burden of stroke is highest. Most studies (94%) provided some information about the activities carried out with their PPI partners, mainly centered on the study design (57%) and management (64%), with only 4% of studies integrating PPI across all research cycle phases from funding application to dissemination. When studies were examined for compliance with the Guidance for Reporting Involvement of Patients and the Public (GRIPP) short-form checklist, only 11% of included studies were 100% compliant. Twenty-one studies (29%) reported barriers and facilitators to including PPI in stroke research. Organization, authentic partnership, and experienced PPI representatives were common facilitators and identified barriers reflected concerns around adequate funding, time required, and diversity in perspectives. A positive reporting bias for PPI impact was observed, summarized as keeping the patient perspective central to the research process, improved care of study participants, validation of study findings, and improved communication/lay-summaries of complex research concepts.
Conclusions: PPI is underutilized and inconsistently reported in current empirical stroke research. PPI must become more widely adopted, notably in low- and middle-income countries. Consensus-driven standards for inclusion of PPI by funding organizations and publishers are required to support its widespread adoption.
背景:要解决中风给全球带来的沉重负担,需要在监测、预防、急性期治疗和康复方面为中 风幸存者提供有影响力的循证解决方案。患者和公众参与(Patient and Public Involvement,PPI),即患者、患者家属和公众作为研究伙伴积极参与,可提高中风相关研究的相关性、可信度和影响力。目的:本范围界定综述遵循 PRISMA 范围界定综述指南,旨在确定和总结目前在实证中风研究中如何使用参与式方法实施和报告 PPI:制定并实施了全面的检索策略,涵盖 Medline、CINAHL、EMBASE、PsynchINFO 和 Cochrane 电子数据库,并辅以灰色文献检索。纳入了从 2014 年到 2023 年发表的、记录 PPI 活动的英文脑卒中实证研究论文。在确定的 18,143 篇原始论文中,筛选了 2,824 篇与该时间窗口匹配的全文手稿。其中只有 2%(n=72)直接报告了实证研究中的嵌入式 PPI 活动。大多数研究采用定性设计(60%),在高收入国家进行(96%)。只有一项纳入的研究来自中风负担最重的发展中国家。大多数研究(94%)提供了一些有关与其 PPI 合作伙伴开展活动的信息,主要集中在研究设计(57%)和管理(64%)方面,只有 4% 的研究将 PPI 纳入了从资金申请到传播的所有研究周期阶段。在检查研究是否符合《患者和公众参与报告指南》(GRIPP2)简表清单时,只有 11% 的纳入研究 100%符合要求。21项研究(29%)报告了将患者和公众参与纳入卒中研究的障碍和促进因素。组织、真实的合作关系和经验丰富的 PPI 代表是常见的促进因素,已确定的障碍反映了对充足资金、所需时间和观点多样性的担忧。研究发现,PPI 的影响存在积极的报告偏差,概括为将患者视角置于研究过程的中心位置、改善对研究参与者的护理、验证研究结果以及改善复杂研究概念的沟通/非专业总结:结论:在目前的卒中实证研究中,PPI 未得到充分利用,报告也不一致。必须更广泛地采用 PPI,尤其是在中低收入国家。为支持 PPI 的广泛采用,资助机构和出版商需要制定以共识为导向的 PPI 纳入标准。

Empirical stroke research articles in the English language, published from 2014 up to 2023, and documenting PPI activity were included. Of the 18,143 original articles identified, 2824 full-text manuscripts matching from this time window were screened. Only 2% (n = 72) of these directly reported embedded PPI activity in empirical research. The majority were qualitative in design (60%) and conducted in high-income countries (96%). Only one included study originated from a developing country, where the burden of stroke is highest. Most studies (94%) provided some information about the activities carried out with their PPI partners, mainly centered on the study design (57%) and management (64%), with only 4% of studies integrating PPI across all research cycle phases from funding application to dissemination. When studies were examined for compliance with the Guidance for Reporting Involvement of Patients and the Public (GRIPP) short-form checklist, only 11% of included studies were 100% compliant. Twenty-one studies (29%) reported barriers and facilitators to including PPI in stroke research. Organization, authentic partnership, and experienced PPI representatives were common facilitators and identified barriers reflected concerns around adequate funding, time required, and diversity in perspectives. A positive reporting bias for PPI impact was observed, summarized as keeping the patient perspective central to the research process, improved care of study participants, validation of study findings, and improved communication/lay-summaries of complex research concepts.</p><p><strong>Conclusions: </strong>PPI is underutilized and inconsistently reported in current empirical stroke research.
