Angiography-based hemodynamic features predict recurrent ischemic events after angioplasty and stenting of intracranial vertebrobasilar atherosclerotic stenosis. Eur Radiol 2024; 34:2352-2363. [PMID: 37723287 PMCID: PMC10957605 DOI: 10.1007/s00330-023-10209-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 07/05/2023] [Accepted: 07/20/2023] [Indexed: 09/20/2023]
Abstract
OBJECTIVES To assess the predictive value of hemodynamic features for stroke relapse in patients with intracranial vertebrobasilar atherosclerotic stenosis treated with percutaneous transluminal angioplasty and stenting (PTAS) using quantitative digital subtraction angiography (q-DSA). METHODS In this retrospective longitudinal study, patients with intracranial vertebrobasilar atherosclerotic stenosis and who underwent PTAS treatment between January 2012 and May 2020 were enrolled. The q-DSA assessment was performed before and after PTAS. ROIs 1-4 were placed along the vertebral artery, proximal and distal basilar artery, and posterior cerebral artery; ROIs 5-8 were in 5 mm and 10 mm proximal and distal to the lesion, respectively. Relative time to peak (rTTP) was defined as the difference in TTP between ROIs. Cox regression analyses were performed to determine risk factors for recurrent stroke. RESULTS A total of 137 patients (mean age, 62 years ± 10 [standard deviation], 83.2% males) were included, and 26 (19.0%) patients had stroke relapse during follow-up (median time of 42.6 months [interquartile range, 19.7-60.7]). Preprocedural rTTP4-1 (adjusted hazard ratio (HR) = 2.270; 95% CI 1.371-3.758; p = 0.001) and preprocedural rTTP8-5 (adjusted HR = 0.240; 95% CI 0.088-0.658; p = 0.006) were independently associated with the recurrent stroke. These hemodynamic parameters provided an incremental prognostic value for stroke relapse (AUC, 0.817 [0.704-0.931]; the net reclassification index, 0.431 [0.057-0.625]; and the integrated discrimination index, 0.140 [0.035-0.292]). CONCLUSIONS In patients with intracranial vertebrobasilar atherosclerosis treated with PTAS, preprocedural prolonged TTP of the target vessel and shortened trans-stenotic TTP difference were associated with stroke relapse. Q-DSA-defined hemodynamic parameters provided incremental predictive value over conventional parameters for stroke recurrence. CLINICAL RELEVANCE STATEMENT Quantitative DSA analysis enables intuitive observation and semi-quantitative evaluation of peri-therapeutic cerebral blood flow. More importantly, quantitative DSA-defined hemodynamic parameters have the potential for risk stratification of patients with intracranial atherosclerotic stenosis. KEY POINTS Semi-quantitative angiography-based parameters can reflect pre- and postprocedural subtle changes in blood flow in patients with intracranial atherosclerotic stenosis. Although angioplasty procedures can significantly improve blood flow status, patients with more restricted baseline blood flow still show a higher risk of stroke recurrence. Angiography-based hemodynamic features possess prognostic value and can serve as clinical markers to assess stroke risk of patients with intracranial atherosclerotic stenosis.

Nutr Metab Cardiovasc Dis 2024; 34:112-120. [PMID: 37798237 DOI: 10.1016/j.numecd.2023.08.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 08/07/2023] [Accepted: 08/17/2023] [Indexed: 10/07/2023]
Abstract
BACKGROUND AND AIM Stroke incidence rates are rising among young adults. Liver fibrosis has recently been recognized as a risk factor for cardiovascular events and stroke in the general population. It remains unclear whether liver fibrosis influences the prognosis of stroke. We aimed to evaluate the association between liver fibrosis and stroke recurrence in young stroke patients. METHODS AND RESULTS Young adults with first-ever ischemic stroke were enrolled from a prospective stroke registry and were followed up for stroke recurrence. Liver fibrosis was evaluated by Fibrosis-4 (FIB-4) score and was stratified into three categories. Cox regression analysis was performed to assess the relationship between liver fibrosis and stroke recurrence. Over a median follow-up of 3.1 (1.7-4.6) years, 72 (11.6%) recurrent strokes occurred among 621 patients. According to the FIB-4 score, 73 (11.7%) patients had indeterminate fibrosis, while 11 (1.8%) had advanced fibrosis. Univariate Cox analysis revealed that patients with a high FIB-4 score were more likely to experience stroke recurrence than those with a low FIB-4 score (hazard ratio 3.748, 95% confidence interval 1.359-10.332, P = 0.011). After adjusting for potential confounders in the multivariate analysis, FIB-4 score remained an independent risk factor. CONCLUSIONS Young stroke patients with advanced liver fibrosis were at a greater risk of stroke recurrence. Evaluating liver fibrosis may provide valuable information for stroke risk stratification, and the FIB-4 score could serve as a useful tool.

Abstract
BACKGROUND Glycemic gap, as a novel index of acute glycemic excursion, is associated with poor prognosis of different diseases. This study aimed to explore the association of the glycemic gap with long-term stroke recurrence in patients with ischemic stroke. METHODS This study included patients with ischemic stroke from the Nanjing Stroke Registry Program. The glycemic gap was calculated by subtracting the estimated average blood glucose from the blood glucose at admission. Multivariable Cox proportional hazards regression analysis was performed to explore the association between the glycemic gap and the risk of stroke recurrence. The Bayesian hierarchical logistic regression model was used to estimate the effects of the glycemic gap on stroke recurrence stratified by diabetes mellitus and atrial fibrillation. RESULTS Among 2734 enrolled patients, 381 (13.9%) patients experienced stroke recurrence during a median follow-up of 3.02 years. In multivariate analysis, glycemic gap (high group vs. median group) was associated with significantly increased risk for stroke recurrence (adjusted hazard ratio, 1.488; 95% confidence interval, 1.140-1.942; p = .003) and had varying effects on stroke recurrence depending on atrial fibrillation. The restricted cubic spline curve showed a U-shaped relationship between the glycemic gap and stroke recurrence (p = .046 for nonlinearity). CONCLUSION Our study found that the glycemic gap was significantly associated with stroke recurrence in patients with ischemic stroke. The glycemic gap was consistently associated with stroke recurrence across subgroups and had varying effects depending on atrial fibrillation.

Does early surgical decompression matter? Clin Neurol Neurosurg 2023; 231:107829. [PMID: 37331206 DOI: 10.1016/j.clineuro.2023.107829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 06/03/2023] [Accepted: 06/05/2023] [Indexed: 06/20/2023]
Abstract
BACKGROUND Even though different subtypes of spontaneous ICH are frequently linked to a poor prognosis, their causes, pathological features, and prognoses vary. Atypical intracerebral hemorrhage is the subtype of spontaneous ICH that usually occurs due to an underlying localized vascular lesion. It is unrelated to systemic vascular risk factors, mostly affects children and young adults and is associated with a relatively good outcome. This fact should be considered when planning the evaluation and treatment. Investigating the cause of this subtype is fundamental to providing optimal management. However, if resources do not allow completing the investigations, the cause will be more difficult to discover. Treatment decisions will be made under stress to save the patient's life, especially with rapidly deteriorating patients. METHODS We described three cases of spontaneous ICH without systemic risk factors where the bleeding source could not be determined before surgery due to a lack of resources, preventing preoperative vascular investigation. Knowing that the atypical ICH has a distinct identity, regarding etiology and prognosis, encouraged the surgeons to resort to early surgical decompression as an alternative plan. We reviewed the literature searching for supporting evidence. RESULTS The results of treatment of the presented cases were satisfactory. The lack of reported similar cases was brought to light by a literature analysis that sought to provide backing for the proposed management strategy. In the end, we supplied two graphic organizers to help readers remember the different types and treatment of hemorrhagic stroke. CONCLUSION There isn't enough evidence to show that there are other ways to treat atypical intracerebral haemorrhage when resources are limited. The presented cases highlight the importance of decisionmaking in resource-constrained situations when patient outcomes can be improved.

Abstract
BACKGROUND The appropriate timing of resuming antithrombotic therapy after intracerebral hemorrhage (ICH) remains unclear. The aim of this study was to compare the risks of major bleeding between early and late antiplatelet resumption in ICH survivors. METHODS Between 2008 and 2017, ICH patients were available in the National Health Insurance Research Database. Patients with a medication possession ratio of antiplatelet treatment ≥50% before ICH and after antiplatelet resumption were screened. We excluded patients with atrial fibrillation, heart failure, under anticoagulant or hemodialysis treatment, and developed cerebrovascular events or died before antiplatelet resumption. Finally, 1584 eligible patients were divided into EARLY (≤30 days) and LATE groups (31-365 days after the index ICH) based on the timing of antiplatelet resumption. Patients were followed until the occurrence of a clinical outcome, end of 1-year follow-up, death, or until December 31, 2018. The primary outcome was recurrent ICH. The secondary outcomes included all-cause mortality, major hemorrhagic events, major occlusive vascular events, and ischemic stroke. Cox proportional hazard model after matching was used for comparison between the 2 groups. RESULTS Both the EARLY and LATE groups had a similar risk of 1-year recurrent ICH (EARLY versus LATE: 3.12% versus 3.27%; adjusted hazard ratio [AHR], 0.967 [95% CI, 0.522-1.791]) after matching. Both groups also had a similar risk of each secondary outcome at 1-year follow-up. Subgroup analyses disclosed early antiplatelet resumption in the patients without prior cerebrovascular disease were associated with lower risks of all-cause mortality (AHR, 0.199 [95% CI, 0.054-0.739]) and major hemorrhagic events (AHR, 0.090 [95% CI, 0.010-0.797]), while early antiplatelet resumption in the patients with chronic kidney disease were associated with a lower risk of ischemic stroke (AHR, 0.065 [95% CI, 0.012-0.364]). CONCLUSIONS Early resumption of antiplatelet was as safe as delayed antiplatelet resumption in ICH patients. Besides, those without prior cerebrovascular disease or with chronic kidney disease may benefit more from early antiplatelet resumption.

Abstract
Background Systemic immune inflammation has been investigated as a prognostic marker of different diseases. This study is designed to assess the association of systemic immune-inflammation index (SII) with long-term mortality of stroke-associated pneumonia (SAP) patients. Methods Patients aged ≥18 years with SAP were selected from the Nanjing Stroke Registry Program in China. We retrospectively evaluated systemic immune-inflammation response with SII and pneumonia severity with the pneumonia severity index and the confusion, uremia, elevated respiratory rate, hypotension, and aged 65 years or older score. To explore the correlation between SII and mortality in SAP patients, multivariable Cox regressions and competing risk regressions were conducted. Mediation analysis was also performed to assess the role of pneumonia severity. Results Among 611 patients in the SAP population, death occurred in 164 patients (26.8%) during the median follow-up of 3.0 (1.2-4.6) years. In multivariate analysis, higher SII scores could predict increased mortality in patients with SAP (adjusted hazard ratio 2.061; 95% confidence interval, 1.256-3.383; P = 0.004), and the association was mediated by pneumonia severity. Moreover, adding SII to traditional models improved their predictive ability for mortality. Conclusion Our study displayed that SII was characterized in SAP patients with different prognoses. Elevated SII scores increased the risk of mortality. Further research is required for the clinical practice of the index among SAP patients.

Abstract
Background Survival and prognostic factors following stroke occurrence differ between world regions. Studies investigating stroke features in the Middle-east region are scarce. We aimed to investigate 1-year survival and related prognostic factors of stroke patients in Central Iran. Materials and Methods It is an observational analytical study conducted on patients registered in the Persian Registry of Cardiovascular Disease-Stroke (PROVE-Stroke) database. Records of 1703 patients admitted during 2015-2016 with the primary diagnosis of stroke in all hospitals of Isfahan, Iran were reviewed. Information regarding sociodemographic characteristics, clinical presentations, medications, and comorbidities were recorded. The living status of patients after 1 year from stroke was considered as 1-year survival. Results Among 1345 patients with the final diagnosis of stroke, 970 (72.1%) were alive at the 1 year follow-up and the mean survival time based on Kaplan-Meier procedure was estimated 277.33 days. The hemorrhagic and ischemic types of stroke were reported in 201 (15.0%) and 1141 (84.8%) patients, respectively. Age (hazard ratio [HR] = 1.07, 95% confidence interval [CI] = 1.05-1.09), diabetes (HR = 1.49, 95% CI = 1.07-2.06), history of stroke or transient ischemic attack (HR = 1.81, 95% CI = 1.30-2.52), history of warfarin usage (HR = 1.73, 95% CI = 1.11-2.71), hospital complications of hemorrhage (HR = 3.89, 95% CI = 2.07-7.31), sepsis (HR = 1.78, 95% CI = 1.18-2.68), and hydrocephalus (HR = 3.43, 95% CI = 1.34-8.79), and modified Rankin Scale (mRS) ≥3 at the time of hospital dicharge (HR = 1.98, 95% CI = 1.27-3.07), were predictors of 1-year survival. Conclusion Predictors of 1-year survival can be categorized into unchangeable ones, such as age, diabetes, previous stroke, and mRS. The changeable factors, such as hospital complications of infection and hemorrhage, guide physicians to pay greater attention to reduce the risk of mortality following stroke.

Abstract
Objective Intracranial vertebral artery terminated in the posterior inferior cerebellar artery (PICA-VA) is the most popular variant of the posterior inferior cerebellar artery, while its prevalence and clinical significance remained unclear. In the present study, we aimed to investigate the prevalence and clinical significance of PICA-VA. Methods This was a multicenter hospital-based cross-sectional study. Patients were enrolled for cerebral MRI and MRA within 1 week of stroke onset. Clinical characteristics were recorded. PICA-VA is termed as a vertebral artery that does not communicate with the basilar artery but terminates in an ipsilateral PICA. We observed the prevalence of PICA-VA and identified a relationship between PICA-VA and vertebrobasilar stroke. Results From 1 August 2015 to 31 May 2017, a total of 2,528 patients were enrolled in the present study. Among them, 95 patients (3.76%, 95/2,528) had the variation of PICA-VA, 51 of which (53.7%) were located on the right side. The prevalence of vertebrobasilar stroke was considerably higher in patients with PICA-VA than those without (40.2%, 37/92 vs. 17.1%, 417/2,436, p < 0.01). PICA-VA was an independent risk for vertebrobasilar stroke after being adjusted for a history of intracranial hemorrhage, diabetes, body mass index, and triglyceride. Conclusion The present study showed that 3.76% of patients with acute stroke had PICA-VA, which independently increased the risk of acute vertebrobasilar stroke.

The MRI enhancement ratio and plaque steepness may be more accurate for predicting recurrent ischemic cerebrovascular events in patients with intracranial atherosclerosis. Eur Radiol 2022; 32:7004-7013. [PMID: 35771249 DOI: 10.1007/s00330-022-08893-2] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Revised: 03/22/2022] [Accepted: 04/18/2022] [Indexed: 12/28/2022]
Abstract
OBJECTIVES To assess the complementary value of high-resolution multi-contrast MRI (hrMRI) in identifying symptomatic patients with intracranial atherosclerosis (ICAS) who are likely to experience recurrent ischemic cerebrovascular events. METHODS In this retrospective cohort study, eighty patients with acute ischemic events attributed to ICAS who underwent hrMRI examination between January 2015 and January 2019 were included. Median follow-up for all patients was 30 months (range: 1 to 52 months) and recurrent ischemic cerebrovascular events were recorded. Cox regression analysis and time-dependent ROC were performed to quantify the association between the plaque characteristics and recurrent events. RESULTS During the follow-up, 14 patients experienced recurrent ischemic cerebrovascular events. Young males and those with diabetes and poor medication persistence were more likely to experience recurrent events. ICAS in patients with recurrence had significantly higher enhancement ratio and steepness which is defined as the ratio between the plaque height and length than those without (p < 0.001 and p = 0.015, respectively). After adjustment of clinical factors, enhancement ratio (HR, 13.13 [95% CI, 3.58-48.20], p < 0.001) and plaque steepness (HR, 110.27 [95% CI, 4.75-2560.91], p = 0.003) were independent imaging biomarkers associated with recurrent events. Time-dependent ROC indicated that integrated high enhancement ratio and steepness into clinical risk factors improved discrimination power with the ROC increased from 0.79 to 0.94 (p = 0.008). CONCLUSIONS The enhancement ratio and plaque steepness improved the accuracy over traditional clinical risk factors in predicting recurrent ischemic cerebrovascular events for patients with ICAS. KEY POINTS • High-resolution magnetic resonance imaging helps clinicians to evaluate high-risk Intracranial plaque. • The higher enhancement ratio and plaque steepness (= height/length) were the primary biomarkers associated with future ischemic cerebrovascular events. • High-resolution magnetic resonance imaging combined with clinical characteristics showed a higher accuracy for the prediction of recurrent events in patients with intracranial atherosclerosis.

Abstract
Background: Sex differences in stroke outcomes are crucial to secondary prevention but previous reports showed inconsistent results. We aimed to explore the sex differences in stroke outcomes in the Third China National Stroke Registry, a prospective multi-center registry study. Methods: Among the 15166 patients enrolled between 2015 and 2018, 9038 patients with acute ischemic stroke (AIS) were included. The primary outcomes were stroke recurrence, mortality, and unfavorable functional outcome (modified Rankin Scale [mRS] > 2) at 3, 6, and 12 months. Cox regression model was used for stroke recurrence and mortality and logistic regression was used for the unfavorable functional outcome, and adjusted as follows: (1) Model 1: without adjustment; (2) Model 2: adjusted for potential risk factors, National Institutes of Health Stroke Scale (NIHSS) at admission, pre-stroke mRS, tissue plasminogen activator (TPA) treatment, TOAST classification, and onset-to-door time; (3) Model 3: adjusted for covariates from model 2 in addition to blood pressure and blood serum covariates. Multiple imputation was used for missing values, and sensitivity analyses were conducted to describe sex differences by age groups. Results: One-third (2802/9038) of the patients were women. Women were significantly older than men (64.78±10.84 vs. 61.26±11.42, p<0.001). In the fully adjusted model, female patients were more likely to have unfavorable functional outcomes at 3 months (odds ratio [OR], 1.28 [1.09, 1.50]), especially among patients aged 65 years or older (OR, 1.39 [1.14, 1.70]), but no difference was discovered in patients aged < 65 years. There were no sex differences in stroke recurrence and mortality at 3, 6, or 12 months or unfavorable functional outcomes at 6 or 12 months after adjustment. Conclusions: Compared to men, women with AIS were less likely to have favorable outcomes at three months in China, especially among those over 65 years of age. Experts should aim to tailor secondary prevention strategies for high-risk patients.

Abstract
BACKGROUND AND PURPOSE This study aimed to explore the association between triglyceride-glucose (TyG) index and stroke recurrence in elderly patients with ischemic stroke in China. METHODS We enrolled ischemic stroke patients aged ≥ 65 years from the Nanjing Stroke Registry Program. The primary endpoint was defined as recurrent stroke within one year after the index stroke. We used multivariable Cox proportional hazards regression models to investigate the association between TyG index and stroke recurrence. We assessed the discriminative ability of TyG index with the receiver operative characteristic and the area under the curve. RESULTS A total of 955 patients (median age, 70.0 [67.0, 75.0]; male sex, 67.2%) from the Nanjing Stroke Registry Program were enrolled. During one year follow-up, 97 (10.2%) elderly patients experienced stroke recurrence. In multivariable analyses, the association between TyG index and stroke recurrence remained significant after adjusting for confounders (quartile 4 versus quartile 1; hazard ratio, 2.073, 95% confidence interval, 1.158-3.711; P = 0.014). The restricted cubic spline showed an increasing trend for TyG index and stroke recurrence (P for non-linearity = 0.072). The area under the curve to predict stroke recurrence with TyG index was 0.719 (95% confidence interval, 0.666-0.772). Besides, TyG index slightly improved the prediction for stroke recurrence. CONCLUSION Elevated TyG index was associated with stroke recurrence in elderly patients with ischemic stroke. Further studies are warranted to assess the role of TyG index in the development of stroke recurrence in the elderly.

Abstract
OBJECTIVES To compare hospital treatments for major stroke types in Chinese adults by stroke pathological types, sex, age, calendar year, hospital tier, region and other factors. DESIGN Cross-sectional analysis of medical records retrieved from 20 229 stroke cases in the China Kadoorie Biobank. SETTING Ten diverse areas (five urban, five rural) in China. PARTICIPANTS First-incident stroke cases who were recruited during an 11-year follow-up of 0.5M participants in the China Kadoorie Biobank. METHODS Electronic copies of medical records of stroke cases were retrieved for clinical adjudication by local neurologists. Stroke cases were classified as ischaemic stroke (IS) (including lacunar infarction (LACI) and non-LACI (non-LACI)), intracerebral haemorrhage (ICH), subarachnoid haemorrhage (SAH) and unspecified stroke types. RESULTS Among 20 299 first-ever stroke cases, 17 306 (85%) had IS, 7123 had non-LACI, 6690 had LACI, 3493 had silent LACI, 2623 (13%) had ICH and 370 (2%) had SAH. Among IS cases, antiplatelet treatment was used by 64% (65% non-LACI, 66% LACI, 56% silent LACI), lipid-lowering by 50% (52% non-LACI, 53% LACI, 43% silent LACI) and blood pressure-lowering by ~42% of all IS types, with positive trends in the use of these treatments by calendar year and hospital tier. Among ICH cases, 53% used blood pressure-lowering and 10% used lipid-lowering treatments, respectively. In contrast, traditional Chinese medicines (TCMs) were used by 59% of IS (50% non-LACI, 62% LACI, 74% silent LACI), 38% of ICH and 30% of SAH cases, with positive trends by calendar year and by hospital tier. CONCLUSIONS Among IS cases, use of antiplatelet and lipid-lowering medications increased in recent years, but use of TCM still exceeded use of blood pressure-lowering treatment. In contrast, blood pressure-lowering treatment was widely used for ICH, but only half of all ICH cases used blood pressure-lowering treatment.

J Inflamm Res 2021; 14:4605-4614. [PMID: 34548807 PMCID: PMC8449639 DOI: 10.2147/jir.s328383] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2021] [Accepted: 08/28/2021] [Indexed: 01/16/2023] Open
Abstract
Background and Purpose The impact of low-grade inflammation (LGI) on stroke recurrence has not been well studied yet. We aimed to evaluate the association between LGI and stroke recurrence in patients with ischemic stroke. Methods Patients with first-ever ischemic stroke diagnosed within 72 hours of symptoms onset were consecutively recruited from the Nanjing Stroke Registry Program. C-reactive protein (CRP) level, white blood cell (WBC) count, platelet (PLT) count, and neutrophil-to-lymphocyte ratio (NLR) were conceived as low-grade inflammation biomarkers and combined into a standardized LGI score. The association of LGI score with the risk of stroke recurrence was analyzed with multivariate Cox regression models. Analyses accounting for the competing risk of stroke recurrence and death were also performed. Results Of the 1214 patients studied (median age, 61 years; male, 71.6%), 177 (14.6%) patients experienced a recurrent stroke with a median follow-up of 23.0 (interquartile ranges, 14.5-34.0) months. Patients with stroke recurrence had a higher LGI score (median, 3 versus -2; P < 0.001) than those without recurrence. The univariate analysis indicated that patients with LGI scores in the fourth quartile were more likely to have a stroke recurrence (hazard ratios [HR], 4.312; 95% confidence interval [CI], 2.675-6.952; P < 0.001). After adjusting for potential confounders, the association remained significant in the multivariate Cox regression model (HR, 4.080; 95% CI, 2.420-6.879; P < 0.001). Competing risks model and sensitivity analysis further confirmed this conclusion. Conclusion This study showed that an elevated LGI score was associated with a higher risk of stroke recurrence, independent of other vascular risk factors.

Abstract
Objective: To determine the clinical significance of post-procedural abnormal liver function test (ALFT) on the functional outcomes at 90 days in acute ischemic stroke (AIS) treated with mechanical thrombectomy (MT). Methods: In this retrospective observational study, patients with AIS undergoing MT were enrolled from the Nanjing Stroke Registry Program and the multicenter Captor trial. A favorable outcome was defined as a modified Rankin Scale score 0–2 at 90 days. Predictive models were established by multivariable logistic regression. Improved predictive value of models was assessed by continuous net reclassification improvement (NRI) and integrated discrimination improvement (IDI). In addition, multivariable logistic regression and restricted cubic spline were used to analyze dose–response correlations between the severity of ALFT and prognosis. Results: Among 420 patients enrolled, 234 (55.7%) patients were diagnosed as post-procedural ALFT after MT. Patients with post-procedural ALFT had higher National Institute of Health Stroke Scale score on admission (median, 18 vs. 15, p < 0.001) and more pneumonia (65.4 vs. 38.2%, p < 0.001) than those without post-procedural ALFT. Post-procedural ALFT, rather than preprocedural ALFT, was independently associated with favorable outcome (adjusted odds ratio, 0.48; 95% CI 0.28–0.81; p = 0.006). The improvement of predictive model after adding post-procedural ALFT was significant [continuous NRI (value, 0.401; p < 0.001), IDI (value, 0.013; p < 0.001)]. However, the restricted cubic spline indicated no evidence of a dose–response relationship between the severity of post-procedural ALFT and prognosis. Conclusions: In AIS patients treated by MT, post-procedural ALFT was associated with more severe stroke and served as an independent predictor of worse prognosis at 90 days.

Abstract
OBJECTIVES Our study aimed to determine the relationship between serum periostin levels, and the neutrophil-lymphocyte ratio (NLR) with ischemic stroke subtypes, clinical stroke scales, and acute prognosis in patients with acute ischemic stroke. MATERIALS AND METHODS Forty-two ischemic stroke patients and 39 age- and sex-matched healthy volunteers were included in our study. Demographic characteristics including age and gender were recorded. Blood serum periostin and NLR values were evaluated in the first 24 hours after admission. Serum periostin levels were compared with healthy controls of similar age and sex. Lesion localization was determined by cranial CT or diffusion MRI of the patients. Stroke scales were recorded on days 1 and 7 of hospitalization in the study group. RESULTS The mean serum periostin levels were higher than in the control group, but no statistically significant difference was found. There was no correlation between serum periostin levels and prognosis of stroke. First admission NLRs were statistically higher than in the control group. The first admission NLRs were positively correlated with the first admission National Institute of Health Stroke Scale score and the day 7 modified Rankin score. CONCLUSION Our study is the first study to evaluate both NLR and serum periostin levels in all types of acute ischemic stroke. While our study did not show that first admission serum periostin levels can be used as a biomarker in ischemic stroke, it did indicate that the first admission NLR can be used for acute prognosis of ischemic stroke.

Abstract
BACKGROUND & AIMS Malnutrition is associated with poor prognosis of different diseases. This study aimed to investigate the association of malnutrition with long-term mortality of older adults with ischemic stroke in China. METHODS We selected patients aged ≥65 years with first-ever ischemic stroke from the Nanjing Stroke Registry Program. Malnutrition was defined according to the controlling nutritional status score (CONUT), the geriatric nutritional risk index (GNRI), and the prognostic nutritional index score (PNI), respectively. Multivariable Cox proportional hazards regressions and competing risk regressions were performed to explore the relationship between malnutrition and the risk of mortality in older adults with ischemic stroke. RESULTS Among 1065 enrolled patients, 60.5%, 46.7%, and 30.6% of patients were malnourished according to CONUT, GNRI, and PNI score. During a median follow-up of 4.74 (3.73-5.82) years, 205 (19.2%) patients died. In multivariate analysis, malnutrition (severe risk versus normal nutrition) was associated with significantly increased risk for mortality by the CONUT (adjusted hazard ratio [HR] 4.615, 95% confidence interval [CI] 1.373-15.514, P = 0.013), GNRI (adjusted HR 3.641, 95% CI 1.924-6.891, P < 0.001), and PNI score (adjusted HR 1.587, 95% CI, 1.096-2.297, P = 0.014). Furthermore, adding the malnutrition indexes to models modestly improved the predictive ability of mortality. CONCLUSIONS Our study indicated that malnutrition was highly prevalent in older Chinese adults with ischemic stroke and associated with increased mortality. Further research is required to evaluate the efficacy of nutritional management in these patients.

A Pre-Interventional Scale to Predict in situ Atherosclerotic Thrombosis in Acute Vertebrobasilar Artery Occlusion Patients. Front Neurol 2021; 12:648081. [PMID: 33897603 PMCID: PMC8058399 DOI: 10.3389/fneur.2021.648081] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Accepted: 02/25/2021] [Indexed: 11/13/2022] Open
Abstract
Background and Purpose: Determining the occlusion mechanism before endovascular treatment (EVT) is of great significance for acute large vessel occlusion patients. We aimed to develop and validate a simple pre-EVT scale with readily available variables for predicting in situ atherosclerotic thrombosis (ISAT) in acute vertebrobasilar artery occlusion (VBAO) patients. Materials and Methods: Consecutive patients were retrieved from Nanjing Stroke Registry Program between January 2014 and December 2019 as a derivation cohort. Anonymous data of consecutive patients between January 2014 and December 2019 were collected from another comprehensive stroke center as an external validation cohort. Demographics, medical histories, and clinical characteristics were collected. ISAT was defined according to the following criteria: (a) detection of moderate to severe (≥50%) stenosis or stenosis with significant distal flow impairment at the occluded segment when successful reperfusion was achieved; (b) transient visualization of eccentric plaque contour or a recurrent re-occlusion tendency when reperfusion was unsuccessful. Logistic regression was taken to develop a predictive scale. The performance of the scale was assessed by area under the receiver operating characteristic curve (AUC) and Hosmer–Lemeshow test. Results: ISAT was observed in 41 of 95 (43.2%) patients included in the derivation cohort. The ISAT predictive scale consisted of three pre-interventional predictors, including the history of hypertension, atrial fibrillation rhythm, and baseline serum glucose level ≥7.55 mmol/L. The model depicted acceptable calibration (Hosmer–Lemeshow test, P = 0.554) and good discrimination (AUC, 0.853; 95% confidence interval, 0.775–0.930). The optimal cutoff value of the ISAT scale was 1 point with 95.1% sensitivity, 64.8% specificity, and 77.9% accuracy. In the validation cohort, the discrimination ability was still promising with an AUC value of 0.800 (0.682–0.918). Conclusion: The three-item scale comprised of the history of hypertension, atrial fibrillation rhythm, and dichotomous serum glucose level had a promising predictive value for ISAT before EVT in acute VBAO patients.

Management characteristics and prognosis after stroke in China: findings from a large nationwide stroke registry. Stroke Vasc Neurol 2021; 6:1-9. [PMID: 32571805 PMCID: PMC8005905 DOI: 10.1136/svn-2020-000340] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Revised: 04/14/2020] [Accepted: 04/20/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND AND PURPOSE There is limited nationwide evidence about the standard management characteristics of stroke types and prognosis in China. This study aimed to assess clinical characteristics, in-hospital and after-discharge management characteristics and prognosis for stroke types in China. METHODS A nationwide registry recruited 14 244 imaging-confirmed first-ever incident strokes from 132 hospitals across 31 provinces of China during 2007-2008, recording presenting characteristics, diagnostic procedures and in-hospital treatment. After hospital discharge, patients were followed up for 6 months. Conventional statistical methods were used to examine the patterns of management and prognosis. RESULTS Overall, 68.7%, 26.9% and 4.4% were ischaemic stroke (IS), intracerebral haemorrhage (ICH), and subarachnoid haemorrhage (SAH), respectively. Only 20% were managed in a dedicated stroke unit. Among IS, 1.3% received thrombolysis within 3 hours after symptom onset, whereas the proportions of receiving in-hospital antiplatelet therapy, neuroprotective agents and traditional Chinese medicines (TCM) were 88.4%, 69.7% and 70.6%, respectively. For ICH, 63.3% and 36.3% received neuroprotective agents and TCM in hospital, respectively. At discharge, 70.7% and 38.0% of the patients with IS were given antiplatelet and statin therapies, respectively, decreasing to 64.8% and 23.9%, respectively, at 6 months. In-hospital mortality was 3.2%, 9.3% and 10.1% for IS, ICH and SAH, respectively, with a further 8.6%, 18.2% and 22.0%, respectively, died by 6 month. Meanwhile, in-hospital recurrence rate was 2.6%, 1.9% and 7.2% for IS, ICH and SAH, respectively, with a further 8.0%, 5.1% and 7.5%, respectively, recurred by 6 month. CONCLUSIONS In China, the mortality rate of stroke is lower than that reported from west populations, though most strokes are not managed in specialised stroke unit. There is widespread use of some unproven therapies but limited proven treatments, especially after discharge, leading to unnecessary recurrent risks.

BMC Neurol 2021; 21:92. [PMID: 33639875 PMCID: PMC7913397 DOI: 10.1186/s12883-021-02122-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Accepted: 02/23/2021] [Indexed: 11/17/2022] Open
Abstract
Background We aimed to assess the safety and efficacy of endovascular treatment (EVT) in patients with anterior circulation emergent large vessel occlusion (ELVO) beyond 6 h from symptom onset in a real-world cohort of patients in China. Methods We retrospectively examined 305 patients with anterior circulation ELVO treated with EVT. Patients were divided into two groups: treated with known onset within 6 h (n = 238) and beyond 6 h (n = 67). Multivariable logistic regression and ordinal shift analyses were used to evaluate the associations between onset-to-groin puncture time and safety and efficacy outcomes. Results Treatment beyond 6 h was not associated with symptomatic intracranial hemorrhage within 48 h (sICH; odds ratio [OR] 2.03, 95% confidence interval [CI] 0.48–8.57, p = 0.334), in-hospital mortality (OR 1.95, 95% CI 0.48–7.91, p = 0.348), successful recanalization (modified Thrombolysis in Cerebral Infarction score 2b or 3; OR 0.73, 95% CI 0.31–1.73, p = 0.470), favorable functional outcome (modified Rankin Scale score 0–2; OR 0.55, 95% CI 0.25–1.23, p = 0.145), and functional improvement (modified Rankin Scale shift by 1-point decrease; common OR 0.80, 95%CI 0.45–1.42, p = 0.450) at 3 months compared with treatment within 6 h. Futher interaction analysis showed that stroke etiology did not modify the associations between onset-to-groin puncture time and outcomes (p > 0.05). Conclusions In this real-world study, after careful assessment, EVT beyond 6 h from known stroke onset was safe, effective and had comparable short-term outcomes to EVT within 6 h.

Abstract
BACKGROUND Stroke contributes to a significant proportion of deaths and disability worldwide, with a high fatality rate within 30 days following a first ever stroke. We describe the outcomes within one year among patients who succumbed a first ever stroke and survived the first 30 days. METHODS Participants were patients who survived after 30 days from succumbing a first ever stroke admitted at the Muhimbili University of Health and Allied Sciences Academic Medical Center. Stroke survivors or their next of kin were contacted at one year after succumbing a first stroke to determine the outcomes. We assessed participants' vital status and level of disability using the modified Rankin scale. Assessment on utilization of stroke secondary preventive measures among survivors was done by an interviewer-based questionnaire that assessed the number of times participants attended follow up clinics, medication refill and adherence. Participants were examined for waist-hip ratio, body mass index and blood pressure. Cholesterol levels were assessed at one year post first stroke for survivors. Outcomes were summarized as proportions, survival at one year was estimated by using the Kaplan Meier analysis and Cox regression analysis was performed to determine for predictors of mortality. RESULTS We recruited 130 first stroke survivors. Mortality within one year was 53/130 (40.8%) and disability rate measured by Modified Rankin Scale with scores of 3-5 was 29/77 (37.7%) among survivors. Factors associated with mortality were residual disability HR = 8.60, {95% CI (1.16-63.96)}, severe stroke, HR = 2.67 {95% CI (1.44-4.95)} and residing in Dar-es-Salaam HR = 2.15 {95% (CI 1.06-4.36)}. Non-adherence rates to antihypertensives, antiplatelets and statins was 11/73 (15.1%), 9/23 (39.1%) and 18/22 (81.8%) respectively. Attendance rates of follow-up clinics among all survivors and physiotherapy among survivors with disability are 45/77 (58.4%) and 16/29 (55.2%) respectively. CONCLUSIONS The mortality and disability rates within a year following a first ever stroke among 30 days stroke survivors is high. Secondary stroke preventive measures should be enhanced to mitigate stroke adverse outcomes. Community outreach programs could be useful interventions in preventing the adverse outcomes of stroke.

Abstract
Context: Stroke is a condition that may affect the functionality of a person to a significant degree; however, there is very little data available that speaks about the objective state of a patient from a revalidated scale after the post-stroke event. Aims: To fill the knowledge gap and generate first-hand evidence about the post-stroke events in the community. To study post-stroke well-being of patients discharged from health facility and assess them longitudinally by Relevant Physical Examination, National Institute of Health stroke scale, and Modified Rankin Scale. Methods and Materials: Forty patients who suffered from first episode of stroke were followed in their home longitudinally by Relevant Physical Examination, National Institute of Health (NIH) stroke scale and Modified Rankin Scale. Patients under study were first visited after 2 months of discharge from the hospital set up after which two more follow-up visits were conducted at 2 months interval each. Results: There was an improvement in muscle power, sensation in the upper and lower limb, gait, and posture as well as language and vision in the patients in three subsequent visits. There was no significant difference in the fine movements of the patients. There was a gradual improvement in NIH score and there was a dominant presence of moderate-severe disability among the patients. Conclusions: Quantitative scales largely showed on a primary basis that on the physical dimension of the disease, the effects of Stroke were affecting the functioning of the body at optimum capacity and harmony.

Abstract
Background: The dilation of intracranial large arteries caliber, may transfer more hemodynamic burden to the downstream brain capillaries, which, in the long run, results in cerebral small vessel disease (CSVD). This study aimed to investigate the relationship between intracranial artery calibers and small vessel disease. Methods: Patients with first-ever ischemic stroke of lacunar infarction subtype were enrolled via Nanjing Stroke Registry Program. An intracranial arterial Z-score, named the brain arterial remodeling (BAR) score, was calculated by averaging the calibers of the seven main intracranial arteries. Among the enrolled patients, those with a BAR score < −1 SD were deemed to have small intracranial artery calibers; those with a BAR score >1 SD were deemed to have large intracranial artery calibers and those with a between BAR score were deemed to have normal intracranial artery calibers. Imaging markers of CSVD, including lacuna, white matter hyperintensity (WMH), enlarged perivascular spaces (EPVS) and cerebral microbleeds (CMBs) were rated and then summed to obtain a total CSVD score. Results: A total of 312 patients were involved in this study, patients with BAR score >1 SD were older (P = 0.039), and more prone to having a history of myocardial infarction (P = 0.033). The Spearman's rank correlation coefficient between the BAR score and total CSVD score is 0.320 (P < 0.001). Binary logistic regression found that BAR score >1 SD was correlated with lacuna (OR = 1.987; 95% CI, 1.037–3.807; P = 0.039); severe WMH (OR = 1.994; 95% CI, 1.003–3.964; P = 0.049); severe EPVS (OR = 2.544; 95% CI, 1.299–4.983; P = 0.006) and CSVD (OR = 2.997; 95% CI 1.182–7.599; P = 0.021). Ordinal logistic regression analysis found that age (OR = 1.028; 95% CI, 1.007–1.049; P = 0.009), hypertension (OR = 3.514; 95% CI, 2.114–5.769; P < 0.001) and BAR score >1 SD (OR = 2.418; 95% CI, 1.350–4.330; P = 0.003) were correlated with the total CSVD score. Conclusions: Patients with large intracranial arterial calibers may have heavier CSVD burden. The mechanisms of this association warrant further study.

Abstract
Background and Purpose:
Data on long-term survival and recurrence after stroke are lacking. We investigated time trends in ischemic stroke case-fatality and recurrence rates over 20-years stratified by etiological subtype according to the Trial of ORG 10172 in Acute Stroke Treatment classification within a population-based stroke register in Germany.
Methods:
Data was collected within the Erlangen Stroke Project, a prospective, population-based stroke register covering a source population of 105 164 inhabitants (2010). Case fatality and recurrence rates for 3 months, 1 year, and 5 years were estimated with Kaplan-Meier estimates. Sex-specific time trends for case-fatality and recurrence rates were estimated with Cox regression. We adjusted for age, sex, and year of event and stratified for etiological subtypes. A sensitivity analysis with competing risk analysis for time trends in recurrence were performed.
Results:
Between 1996 and 2015, 3346 patients with first ischemic stroke were included; age-standardized incidence per 100 000 was 75.8 in women and 131.6 in men (2015). Overall, 5-year survival probabilities were 50.4% (95% CI, 47.9–53.1) in women and 59.2% (95% CI, 56.4–62.0) in men; 5-year survival was highest in patients with first stroke due to small-artery occlusion (women, 71.8% [95% CI, 67.1–76.9]; men, 75.9% [95% CI, 71.3–80.9]) and lowest in cardioembolic stroke (women, 35.7% [95% CI, 31.0–41.1]; men, 47.8% [95% CI, 42.2–54.3]). Five-year recurrence rates were 20.1% (95% CI, 17.5–22.6) in women and 20.1% (95% CI, 17.5–22.7) in men; 5-year recurrence rate was lowest in women in stroke due to small artery occlusion 16.0% (95% CI, 11.7–20.1) and in men in large-artery atherosclerosis 16.6% (95% CI, 8.7–23.9); highest risk of recurrence was observed in undefined strokes (women, 22.3% [95% CI, 17.8–26.6]; men, 21.4% [95% CI, 16.7–25.9]). Cox regression revealed improvements in case-fatality rates over time with differences in stroke causes. No time trends in recurrence rates were observed.
Conclusions:
Long-term survival and recurrence varied substantially by first stroke cause. Survival probabilities improved over the past 2 decades; no major trends in stroke recurrence rates were observed.

Abstract
Background Smoking is a well‐established risk factor of stroke and smoking cessation has been recommended for stroke prevention; however, the impact of smoking status on stroke recurrence has not been well studied to date. Methods and Results Patients with first‐ever stroke were enrolled and followed in the NSRP (Nanjing Stroke Registry Program). Smoking status was assessed at baseline and reassessed at the first follow‐up. The primary end point was defined as fatal or nonfatal recurrent stroke after 3 months of the index stroke. The association between smoking and the risk of stroke recurrence was analyzed with multivariate Cox regression model. At baseline, among 3069 patients included, 1331 (43.4%) were nonsmokers, 263 (8.6%) were former smokers, and 1475 (48.0%) were current smokers. At the first follow‐up, 908 (61.6%) patients quit smoking. After a mean follow‐up of 2.4±1.2 years, 293 (9.5%) patients had stroke recurrence. With nonsmokers as the reference, the adjusted hazard ratios for stroke recurrence were 1.16 (95% CI, 0.75–1.79) in former smokers, 1.31 (95% CI, 0.99–1.75) in quitters, and 1.93 (95% CI, 1.43–2.61) in persistent smokers. Among persistent smokers, hazard ratios for stroke recurrence ranged from 1.68 (95% CI, 1.14–2.48) in those who smoked 1 to 20 cigarettes daily to 2.72 (95% CI, 1.36–5.43) in those who smoked more than 40 cigarettes daily (P for trend <0.001). Conclusions After an initial stroke, persistent smoking increases the risk of stroke recurrence. There exists a dose–response relationship between smoking quantity and the risk of stroke recurrence.

Abstract
SNP rs2043211 in CARD8 was found to have significant association with ischemic stroke. This study aimed to explore the possible association between rs2043211 and large-artery atherosclerosis stroke in Chinese and explain the possible mechanism. In total, 716 large-artery atherosclerosis stroke patients and 1088 controls were included in the study. Co-dominant, dominant, and recessive genetic models were constructed to evaluate the relationship between rs2043211 and large-artery atherosclerosis stroke risk by odds ratios with 95% confidence intervals. Stratified and interaction analyses were also done. We selected another 111 large-artery atherosclerosis stroke patients and measured the CARD8 levels in their plasma samples by enzyme-linked immunosorbent assay. Participants who carry T/T genotype have a higher risk of large-artery atherosclerosis stroke compared with those carry A/T or A/A genotypes (odds ratio = 1.35, 95% confidence intervals 1.03-1.77, P = 0.029). The higher risk for the T/T genotype is still notable in female, people with hypertension, and people without diabetes. In the interaction analysis, compared to the non-hypertensive participants with the wild homozygote type A/A, the hypertensive participants with the A/T+T/T homozygote had 3.27-fold increased risk (odds ratio = 3.27, 95% confidence intervals 2.33-4.60). The A/A group had lower CARD8 levels in plasma than the A/T and T/T group (P < 0.001). Further bioinformatics prediction indicated that the rs2043211 could significantly influence the mRNA secondary structure and protein expression of CARD8 (eQTL P = 9.8 × 10-198). The rs2043211 is probably a novel biomarker for large-artery atherosclerosis stroke in Chinese.

Abstract
Collateral density variations are a major determinant of stroke outcome. Here, we explored the association of missense variants in hypoxia-induced VEGFA/VEGFR2 signaling and stroke outcome. We recruited 683 large artery atherosclerotic (LAA) stroke patients as the training set from Nanjing Stroke Registry Program between August 2013 and January 2016. To validate the findings from the training set, we recruited an additional 333 LAA stroke patients between February 2016 and January 2017 as the validation set. Genotyping of target SNPs (rs11549465 [HIF-1α], rs11549467 [HIF-1α], rs1870377 [VEGFR2], and rs2305948 [VEGFR2]) was conducted using a SNPscan method. Unfavorable outcome was defined as a modified Rankin Scale (mRS) score > 2 at three months after index event. In the training set, the AA genotype of rs1870377 led to a decreased risk of unfavorable outcomes in the recessive model (AA vs. TA + TT, OR 0.60, 95% CI 0.38-0.95, P = 0.031). This was confirmed in the validation set (OR 0.43, 95% CI 0.21-0.86, P = 0.017) and the combined set (OR 0.54, 95% CI 0.36-0.79, P = 0.002). We also found that A allele was a protective factor for stroke outcome in both validation set and combined set (OR 0.70, 95% CI 0.49-0.99, P = 0.044 and OR 0.77, 95% CI 0.63-0.94, P = 0.012, respectively). In silico analysis indicated that the rs1870377 variant led to structural alterations in VEGFR2 that may influence its activity. Our findings demonstrate that the rs1870377 in the hypoxia-induced VEGFA/VEGFR2 axis predicts the 3-month outcome of patients with LAA stroke.

Abstract
Background and Purpose—
This study aimed to develop and validate a nomogram for predicting the risk of stroke recurrence among young adults after ischemic stroke.
Methods—
Patients aged between 18 and 49 years with first-ever ischemic stroke were selected from the Nanjing Stroke Registry Program. A stepwise Cox proportional hazards regression model was employed to develop the best-fit nomogram. The discrimination and calibration in the training and validation cohorts were used to evaluate the nomogram. All patients were classified into low-, intermediate-, and high-risk groups based on the risk scores generated from the nomogram.
Results—
A total of 604 patients were enrolled in this study. Hypertension (hazard ratio [HR], 2.038 [95% CI, 1.504–3.942];
P
=0.034), diabetes mellitus (HR, 3.224 [95% CI, 1.848–5.624];
P
<0.001), smoking status (current smokers versus nonsmokers; HR, 2.491 [95% CI, 1.304–4.759];
P
=0.006), and stroke cause (small-vessel occlusion versus large-artery atherosclerosis; HR, 0.325 [95% CI, 0.109–0.976];
P
=0.045) were associated with recurrent stroke. Educational years (>12 versus 0–6; HR, 0.070 [95% CI, 0.015–0.319];
P
=0.001) were inversely correlated with recurrent stroke. The nomogram was composed of these factors, and successfully stratified patients into low-, intermediate-, and high-risk groups (
P
<0.001).
Conclusions—
The nomogram composed of hypertension, diabetes mellitus, smoking status, stroke cause, and education years may predict the risk of stroke recurrence among young adults after ischemic stroke.

TNFRSF11B polymorphisms predict poor outcome after large artery atherosclerosis stroke. Gene 2020; 743:144617. [PMID: 32222535 DOI: 10.1016/j.gene.2020.144617] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2019] [Revised: 02/19/2020] [Accepted: 03/23/2020] [Indexed: 01/01/2023]
Abstract
Osteoprotegerin is involved in the progression of atherosclerosis. This study aimed to determine whether TNFRSF11B polymorphisms are associated with prognosis of large artery atherosclerosis (LAA) stroke. Three TNFRSF11B polymorphisms (rs2073617, rs2073618 and rs3134069) were genotyped in 1010 patients with LAA stroke. Short-term outcome was evaluated using the modified Rankin Scale score at 3-month after stroke onset. Long-term outcome was assessed using the stroke recurrence. We found that rs2073617G was associated with an increased risk of poor outcome of LAA stroke (additive model: odds ratio (OR) = 1.35, 95% confidence interval (CI) = 1.06-1.73). This association was also observed in rs3134069C (additive model: OR = 1.53, 95% CI = 1.10-2.12). Furthermore, when we combined these two polymorphisms according to the numbers of risk alleles (rs2073617G and rs3134069C), we found that the patients with 3-4 risk alleles were statistically significantly associated with an increased risk of poor outcome of LAA stroke (OR = 1.90, 95% CI = 1.10-3.28) compared with 0-2 risk alleles, and this increased risk was more evident among those with hypertension (OR = 2.02, 95% CI = 1.04-3.91), those without diabetes (OR = 2.02, 95% CI = 1.02-4.01) and those with smoking (OR = 2.43, 95% CI = 1.09-5.42). In silico analysis showed that rs2073617 and rs3134069 are located in various histone modification marked regions, DNase I hypersensitive sites and can change the binding of regulatory motifs. Moreover, rs2073617 is also located in the binding site of transcription factors. Our findings suggested that TNFRSF11B polymorphisms may be associated with an increased risk of short-term poor outcome of LAA stroke.

Abstract
Background and Purpose- China bears a heavy burden of stroke because of its large population of elderly people and the propensity for stroke. Previous studies have examined the association between air pollution and stroke mortality or hospital admission. However, the global evidence for adverse effects of air pollution on survival after stroke is scarce. Methods- We used the first national hospital-based prospective registry cohort of stroke in China, which included 12 291 ischemic stroke patients who visited hospitals during 2007 to 2008. All patients were followed for 1-year poststroke. Deaths during the follow-up period were recorded. Participants' 3-year prestroke exposures to ambient PM1, PM2.5, PM10 (particulate matter with aerodynamic diameters ≤1, ≤2.5, and ≤10 μm, respectively) and NO2 (nitrogen dioxide) were estimated by machine learning algorithms with satellite remote sensing, land use information, and meteorological data. Cox proportional hazards models were used to examine the association between air pollution and survival after ischemic stroke. Results- In total, 1649 deaths were identified during the 1-year follow-up period. After controlling for potential confounders, significant associations were observed between exposure to PM1 and PM2.5 and incident fatal ischemic stroke. The corresponding hazard ratios and 95% CIs associated with 10 µg/m3 increase in PM1 and PM2.5 were 1.05 (1.02-1.09) and 1.03 (1.00-1.06), respectively. No significant association was observed for PM10 or NO2 (hazard ratios and 95% CIs, 1.01 [1.00-1.03] and 1.03 [0.99-1.06], respectively). Higher hazard ratios (and 95% CIs) were observed for male, elderly and obese individuals. Conclusions- Prestroke exposure to PM1 and PM2.5 was associated with increased incident fatal ischemic stroke in the year following an ischemic stroke in China. Improved air quality may be beneficial for people to recover from stroke.

Abstract
BACKGROUND The topographic location of acute pontine infarction is associated with clinical syndromes and prognosis. Previous studies focused on isolated pontine infarction, but the topographic location of unisolated pontine infarction has remained unclear. METHODS This was a prospective, multicenter, longitudinal registry study. Patients with acute pontine infarction confirmed by magnetic resonance imaging (MRI) were enrolled. Based on the territory of the pontine artery, the topographic location was divided into anteromedial, anterolateral, tegmental, bilateral and unilateral multiple infarctions. RESULTS From May 1, 2003, to Oct 31, 2017, 1003 patients were enrolled, and 330 had unisolated pontine infarction. For isolated pontine infarction, 44.9, 19.8, 16.0, 13.1 and 6.2% of patients had anteromedial, anterolateral, tegmental, bilateral and unilateral multiple pontine infarctions, respectively. For unisolated pontine infarction, 30.3, 19.7, 24.5, 15.2 and 10.3% of patients had anteromedial, anterolateral, tegmental, bilateral and unilateral multiple pontine infarctions, respectively. CONCLUSION In this large series study, our data revealed fewer anteromedial infarctions and more tegmental and unilateral multiple infarctions in patients with unisolated pontine infarction than in patients with isolated pontine infarction.

[PMID: 31315603 PMCID: PMC6636033 DOI: 10.1186/s12883-019-1400-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2019] [Accepted: 07/11/2019] [Indexed: 02/05/2023] Open
Abstract
Background Patients with vertebrobasilar dolichoectasia usually have persistent hemodynamic abnormalities, and therefore, may bear an increased risk of stroke. This study aimed to identify risk factors for stroke recurrence in patients with vertebrobasilar dolichoectasia. Methods Patients with acute ischemic stroke were screened and evaluated for eligibility. Enrolled patients were followed via scheduled clinical visits or telephone interviews. Ischemic stroke recurrence was proposed with clinical symptoms and confirmed with cranial Magnetic Resonance Imaging or Computerized Tomography scans. Baseline characteristics and vascular geometry were compared between patients with and without stroke recurrence. Significant parameters were introduced into COX proportional hazard model to detect possible predictors of stroke recurrence. Results A total of 115 stroke patients with vertebrobasilar dolichoectasia were enrolled, of which 22 (19.1%) had recurrence during 22 ± 6 months follow-up. Basilar artery diameter ≥ 5.3 mm (HR = 4.744; 95% CI, 1.718–13.097; P = 0.003), diffuse intracranial dolichoectasia (HR = 3.603; 95% CI, 1.367–9.496; P = 0.010) and ischemic heart disease history (HR = 4.095; 95% CI, 1.221–13.740; P = 0.022) had increased risk of recurrence. Conclusions Stroke patients with vertebrobasilar dolichoectasia may have a high risk of recurrence. Larger basilar artery diameter or diffuse intracranial dolichoectasia may increase the risk of recurrence.

Abstract
BACKGROUND AND AIMS A recent genome-wide association study (GWAS) reported an association between a single nucleotide polymorphism (SNP) rs11196288 and risk of early-onset large artery atherosclerotic (LAA) stroke in European population. The interaction between genetic and environmental factors such as age has also received increasing attention. We performed this study to investigate the association between the rs11196288A > G polymorphism and LAA stroke risk in the Chinese Han population and test whether age interacts rs11196288 to influence LAA stroke risk. METHODS Genotyping of rs11196288 was performed in 1066 LAA stroke patients and 1167 healthy controls. Multivariate logistic regression analyses were applied to assess the effect of the rs11196288A > G polymorphism on susceptibility and short-term outcome of LAA stroke. Nomograms were performed to estimate probability of risk for an individual patient. RESULTS A significant decrement of LAA stroke risk was found in co-dominant (AG vs. AA, OR = 0.76, 95% CI = 0.64-0.91, P = 0.003; GG vs. AA, OR = 0.65, 95% CI = 0.50-0.85, P = 0.002), dominant (AG/GG vs. AA, OR = 0.74, 95% CI = 0.62-0.87, P < 0.001) and recessive models (GG vs. AA/AG, OR = 0.76, 95% CI = 0.59-0.97, P = 0.028) of rs11196288. However, the interaction between age and genotypes of rs11196288 was not statistically significant, and no significant association was observed between the rs11196288A > G polymorphism and short-term outcome of LAA stroke (P > 0.05). CONCLUSIONS In the southeastern Chinese population, the rs11196288A > G polymorphism is associated with decreased risk of LAA stroke.

Abstract
Recently, a genome-wide association study (GWAS) detected two histone deacetylase 9 (HDAC9) polymorphisms (rs2074633 and rs28688791) which may be associated with risk of large artery atherosclerotic (LAA) stroke. This study aimed to investigate whether these two polymorphisms were associated with susceptibility, severity, and short-term outcome of LAA stroke in a southern Chinese Han population. rs2074633 and rs28688791 were genotyped using SNPscan technology in 1011 LAA stroke patients and 1121 healthy controls. Stroke severity on admission and short-term outcome were, respectively, assessed by the National Institute of Health Stroke Scale (NIHSS) score on admission and modified Rankin Scale score at 3 months after stroke onset. rs2074633 (P = 0.039) and rs28688791 (P = 0.025) were associated with risk of LAA stroke. In subgroup analysis according to sex and age, this increased risk was only found in males (P = 0.029 for rs2074633; P = 0.013 for rs28688791) and adults aged < 60 years (P = 0.009 for rs2074633; P = 0.003 for rs28688791). Moreover, we detected significant interactions between these two polymorphisms and age (Pinteraction = 0.027 for rs2074633; Pinteraction = 0.044 for rs28688791). The CC genotype of rs28688791 (P = 0.037) was also associated with moderate and severe stroke (NIHSS ≥ 6). Additionally, the CC genotype of rs2074633 and rs28688791 (rs2074633, P = 0.019; rs28688791, P = 0.023) showed significant association with unfavorable short-term outcome of LAA stroke. Our results indicated that HDAC9 polymorphisms may be used as biomarkers for susceptibility, severity, and short-term outcome of LAA stroke.

Abstract
BACKGROUND A recent genome-wide association study has identified that rs4376531 variant conferred risk of atherothrombotic stroke (AS) in a Japanese population. This study was to explore the association in Han Chinese population. METHODS A total of 1036 cases and 643 healthy controls were enrolled. We genotyped rs4376531 variant with SNPscan. Multivariate logistic regression analysis was used to determine the association of genetic variation with risk of AS. Interaction analysis was examined by SNPStats web tool. RESULTS After adjusting for gender, age, body mass index (BMI), hypertension, diabetes and smoking, compared with CC genotype, we observed that GC and GG/GC genotypes were associated with a significantly decreased risk of AS (OR = 0.76, 95% CI = 0.58-0.99 and OR = 0.76, 95% CI = 0.58-0.98, respectively). The decreased risk was more obvious among subgroups with high BMI (OR = 0.63, 95% CI = 0.45-0.88), no hypertension (OR = 0.66, 95% CI = 0.46-0.94), diabetes (OR = 0.33, 95% CI = 0.17-0.64), and smoking (OR = 0.65, 95% CI = 0.44-0.95) in the dominant model (GG/GC vs CC). Interaction analysis also revealed that compared with non-diabetic patients with CC genotype, diabetic patients with CC genotype had a 4.48-fold (OR = 4.48; 95% CI = 2.98-6.72) increased risk of AS. CONCLUSION Our data suggested that GC and GG/GC of rs4376531 contributed to a decreased risk of AS while CC genotype, interacting with diabetes, increased the stroke risk in Han Chinese population.

Abstract
Aim: Limited data regarding stroke subtypes exist from South Asian countries. The aim of the study was to determine the pattern of ischemic stroke subtypes and their associated risk factors, in a 10-year long hospital-based registry in the South Indian city of Hyderabad. Materials and Methods: The Hyderabad stroke registry systematically collected clinical, radiological, and laboratory data of fully investigated consecutive stroke patients and studied pattern of ischemic stroke subtypes and their risk factor association. Results: The cohort comprised of 2642 patients: 2072 (78.4%) were ischemic and 570 (21.6%) were hemorrhagic strokes. In the ischemic stroke cohort, the mean age was 54.1 years and 1622 (78.3%) were men. The most common ischemic stroke subtype was large artery atherosclerosis (LAA) comprising 37.6% (n = 779), followed by small vessel occlusion comprising 19.9% (n = 413) and cardioembolism 11% (n = 228). Stroke of other determined etiologies constituted 4.2% (n = 86) and stroke of undetermined etiology was observed in 27.3%. Among patients with LAA, 610 (78.3%) patients had intracranial and 169 (21.7%) had extracranial disease as the underlying mechanism. Risk factor profile demonstrated that hyperlipidemia was significantly associated with LAA and ischemic heart disease with cardioembolic strokes. Conclusions: The study reveals a distinct pattern of ischemic stroke subtypes in the Indian context that has overlapping features of registries from West and East Asian countries. Both large artery and small vessel diseases are substantially represented with a predominance of intracranial atherosclerosis. The study results have significant implications for developing preventive and management strategies for stroke care and research in India.

Abstract
Background To compare the long-term clinical outcomes of different antihypertensive drugs in stable patients after acute hemorrhagic stroke (HS). Methods From January 2001 to December 2013, patients with first-ever primary HS were identified in the National Health Insurance Research Database, Taiwan. Patients with traumatic intracerebral hemorrhage and secondary HS were excluded. Those with first-ever HS were recruited and classified into three groups: (1) angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB); (2) calcium channel blocker (CCB); and (3) other antihypertensive drugs (comparison) groups. Propensity score matching was used to balance the distribution of baseline characteristics, stroke severity, and medications between any two of the three groups. A validation study was performed using the databank of the Stroke Registry in Chang-Gung Healthcare System to reduce the bias. Primary outcomes were recurrent HS, ischemic stroke, any stroke, and all-cause mortality. Results Compared to the comparison group, the ACEI/ARB group [35.4% versus 39.3%; hazard ratio (HR), 0.84; 95% confidence interval (CI), 0.74-0.95] and CCB group (33.0% versus 41.9%; HR, 0.72; 95% CI, 0.64-0.81) had a lower risk of all-cause mortality during long-term follow up. The CCB group had a similar risk of all-cause mortality to the ACEI/ARB group. Risks of recurrent HS, ischemic stroke, or any stroke were not different between the study groups. Conclusions Antihypertensive drug class could be important to long-term outcomes in HS patients in addition to the target control of blood pressure. Both ACEIs/ARBs and CCBs are associated with lower risks of all-cause mortality. Our results may be applied to inform future research on hypertensive control in HS patients.

Abstract
BACKGROUND AND PURPOSE Genome-wide association studies discovered a novel correlation between chromosome 12q24 and ischemic stroke in European populations. This study aimed to determine whether two genetic variants (rs10744777 and rs886205) on chromosome 12q24 can modify the risk of ischemic stroke in Chinese population. METHODS We recruited 1195 patients with ischemic stroke and 642 healthy Chinese individuals. The rs10744777 and rs886205 polymorphisms in aldehyde dehydrogenase2 (ALDH2) was genotyped and compared using multivariate logistic regression. RESULTS The genotype of rs10744777 (CT/TT) was associated with risk of ischemic stroke in males (OR = 1.99, 95% CI = 1.15-3.42, P = 0.013). In contrast, no significant correlation was found in females. Haplotype analysis indicated that haplotype "TA" was associated with increased ischemic stroke risk (OR = 1.85, 95% CI = 1.10-3.12, P = 0.042). Further subtype analysis demonstrated that the rs10744777 (CT/TT) genotype was strongly associated with large artery atherosclerosis subtype in males (OR = 2.27, 95% CI = 1.30-3.95, P = 0.004). After three months follow-up, we found a poorer functional outcome of ischemic stroke associated with the rs886205 GA genotype (OR = 1.76, 95% CI 1.03-3.00, P = 0.057) in males. CONCLUSIONS Genetic polymorphisms in ALDH2 modified ischemic stroke risk and outcome in Chinese males, but not in females.

Abstract
BACKGROUND Stroke is one of the leading causes of disability and mortality in Japan. The aim of the present analysis was to determine the non-acute survival rate after first-ever stroke using data from a large-scale population-based stroke registry in Japan. Methods and Results: Shiga Stroke Registry is an ongoing population-based registry of stroke, which covers approximately 1.4 million residents of Shiga Prefecture in central Japan. A total of 2,176 first-ever stroke patients, who were registered in 2011, were followed up until December 2013. The 2-year cumulative survival rates were estimated using Kaplan-Meier method according to index stroke subtype. Cox proportional hazards models were used to assess predictors of all-cause death. During a 2-year follow-up period, 663 patients (30.5%) died. The 2-year cumulative survival rate after first-ever stroke was 69.5%. There was heterogeneity in 2-year cumulative survival according to stroke subtype: lacunar infarction, 87.2%; large artery infarction, 76.1%; cardioembolic infarction, 55.4%; intracerebral hemorrhage, 65.9%; and subarachnoid hemorrhage, 56.7%. Older age, male sex, medical history, higher Japan coma scale score on admission, and stroke subtype were associated with risk of all-cause death in ≤2 years. CONCLUSIONS In the present population-based stroke registry with a real-world setting in Japan, 2-year cumulative mortality after first-ever stroke is still high (>30%), particularly for cardioembolic infarction, subarachnoid hemorrhage and intracerebral hemorrhage.

Abstract
The inflammatory response plays a vital role in the development of in-stent restenosis (ISR) after carotid angioplasty and stenting (CAS). The neutrophil to lymphocyte ratio (NLR) has been suggested as a sensitive inflammatory marker. We explored the association between NLR and ISR in CAS patients. A total of 427 patients who underwent CAS were enrolled. Neutrophil to lymphocyte ratio was measured before the procedure. Clinical examination and radiographic evaluation were performed at 6 months and annually after the procedure. In-stent restenosis was defined as ≥50% stenosis in the treated lesion. Cox regression was used to identify predictors of ISR after CAS. Of the 459 arteries (in 427 patients) with CAS, 72 (15.7%) were identified with ISR during a mean follow-up of 14.6 (19.1) months (range, 0.7-120.7 months). Increased NLR (≥2.13) was significantly related to ISR in patients with asymptomatic stenosis ( P = .001). However, significance was not observed in symptomatic stenosis. On multivariate analysis, baseline NLR ≥ 2.13 (hazard ratio [HR], 2.74; 95% confidence interval [CI], 1.46-5.14), smoking (HR, 1.99; 95% CI, 1.11-3.58), residual stenosis (HR, 1.12; 95% CI, 1.09-1.15), and baseline glucose level (HR, 1.01; 95% CI, 1.01-1.02) were associated with ISR. Elevated NLR may be a predictor of ISR after CAS for asymptomatic stenosis.

Abstract
Objective To compare outcomes following intracranial stent retriever-based intracranial thrombectomy (SRT) with emergency extracranial internal carotid artery (EICA) stenting or angioplasty alone in patients presenting with acute stroke due to tandem occlusions of the ICA. Methods Consecutive patients with acute anterior tandem occlusion who received an endovascular intervention within 6h of symptom onset between January 2013 and June 2016 were included in this prospective study. Demographic, radiological, procedural and clinical outcome data were compared between the stenting and the angioplasty alone groups. Results Of the 37 patients eligible for the study, 18 had angioplasty alone and 19 underwent stent placement. Successful recanalization rate was statistically significantly higher in the stenting group than in angioplasty alone group (74% vs. 39%) and although not statistically significant, more patients in the stenting group than in the angioplasty alone group had favourable outcomes (63% vs. 50%). There was no significant difference between groups in rates of symptomatic intracranial haemorrhage (SICH), cerebral herniation or mortality. Conclusion This study in a small sample size suggests that among patients with acute anterior tandem occlusion, SRT with EICA stenting tended to achieve higher recanalization and improved clinical outcomes at three months compared with SRT and angioplasty alone with a similar rate of SICH and mortality.

Abstract
Elevated C-reactive protein (CRP) levels increase the risk of poor functional disability in patients with ischemic stroke (IS). This study aimed to investigate the association between CRP gene polymorphisms and 3-month functional disability of large artery atherosclerotic (LAA) stroke in Han Chinese. Patients with first-ever LAA IS were prospectively enrolled in Nanjing Stroke Registry Program between August 2013 and October 2015. Five single-nucleotide polymorphisms (SNPs) (rs876537, rs2794520, rs3093059, rs7553007 and rs11265260) in CRP gene related to CRP levels in Asian by genome-wide association study were genotyped. The functional outcome at 3 months after the index stroke was assessed by the modified Rankin scale. Associations between genotypes and functional outcome of LAA IS were analyzed with logistic regression model. A total of 690 eligible patients (507 males) were evaluated. SNPs rs11265260 (multivariate-adjusted, p = 0.022), rs2794520 (multivariate-adjusted, p = 0.036) and rs3093059 (multivariate-adjusted, p = 0.027) were significantly associated with elevated CRP in acute IS. Two SNPs, rs3093059 (dominant model: adjusted OR 2.49; 95% CI 1.55-4.00; recessive model: adjusted OR 3.67; 95% CI 1.22-11.03) and rs11265260 (dominant model: adjusted OR 2.51; 95% CI 1.56-4.02; recessive model: adjusted OR 4.70; 95% CI 1.63-13.56) independently predicted 3-month poor outcome of first-ever LAA IS, after adjusting for covariates. In addition, haplotype analysis indicated that haplotype GCTGC (adjusted OR 1.76; 95% CI 1.05-2.95; p = 0.031) increased the poor outcome risk. SNPs rs3093059 and rs11265260 in CRP gene may influence the 3-month functional outcome of first-ever LAA IS in Han Chinese.

Abstract
The aim of this study was to determine the distribution of risk factors according to age, gender, subtypes and recurrence of stroke in eastern Croatia. The study included 250 acute stroke patients admitted to University Department of Neurology, Osijek University Hospital Centre in 2011. Patients were grouped according to age, gender, subtypes and recurrence of stroke. The study showed significant differences in the distribution of cigarette smoking, diabetes, cardiomyopathy and hyperuricemia according to patient age. According to gender, male patients had a significantly higher prevalence of smoking and alcohol abuse, whereas in female patients the prevalence of arterial hypertension, atrial fibrillation and hyperuricemia was significantly higher. Regarding stroke subtypes, significant differences were noticed in the prevalence of arterial hypertension, atrial fibrillation, cardiomyopathy and cerebral blood vessel stenosis. Atrial fibrillation was significantly more common in first-ever than in recurrent stroke. Study results identified the groups of patients requiring special attention regarding particular risk factors in eastern Croatia and emphasized the need of developing regional strategies of screening, prevention and holistic care for stroke patients.

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

Abstract
BACKGROUND AND AIMS We aimed to introduce a parameter of anterior borderzone angle (ABZA) to quantitatively evaluate the ACA-MCA leptomeningeal collaterals for middle cerebral artery stenosis (MCAS). METHODS Two hundred seventy-five patients with 50-100% MCAS and 100 controls were included. The 95% reference range of ABZA was obtained from the controls. ABZAtrans was defined as "ABZA/the 95% upper limit." Relationships between ABZA and MCAS, -ABZAtrans and the TICI grade, the American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology (ASITN/SIR) collateral grade were analyzed. An ABZA grade model for the ACA leptomeningeal collaterals was tentatively developed. RESULTS The 95% reference range of ABZA was 0.0º-23.0º. ABZA was significantly associated with MCAS by a function of the fourth power (R2 = 0.723, p < 0.001), and could predict hemodynamic MCAS (≥70%) with an AUC of 0.928 (95% CI 0.903-0.953). ABZAtrans was negatively correlated with the TICI grade (rho = -0.752, p < 0.001) and positively with the ASITN/SIR grade (rho = 0.921, p < 0.001). The ABZA grade was created by rounding -ABZAtrans to a nearest integer, and was closely associated with the ASITN/SIR grade (rho = 0.894, p < 0.001). CONCLUSIONS ABZA can be used as a hemodynamic parameter to quantitatively evaluate ACA leptomeningeal collaterals.

Abstract
Causes of death in both ischemic stroke (IS) and hemorrhagic stroke (HS) subtypes are not comprehensively studied. Between 2008 and 2011, we enrolled 11 215 first-ever stroke patients from the Stroke Registry of Chang-Gung Healthcare System and linked these data to the national death registry. The main causes of death in each stroke subtype were assessed. Patients with HS had higher overall mortality than IS (32.0% vs 18.1%, P < .001). In IS subtypes, large-artery atherosclerosis plus cardioembolism had the worst mortality (40.7%, P < .001). Stroke was the leading cause of death in both IS and HS within the first year. Stroke remained the major cause of death in HS, but cancer was the leading cause of death in IS after the first year. After excluding the patients with previous cancer history, cancer was still an important cause of death in IS and HS, particularly in the IS subtypes of small vessel occlusion, stroke of undetermined etiology, and transient ischemic attack.
