BackgroundParenchymal hemorrhage (PH) is a troublesome complication after endovascular treatment (EVT).ObjectiveTo investigate the incidence, independent predictors, and clinical impact of PH after EVT in patients with acute ischemic stroke (AIS) due to anterior circulation large vessel occlusion (LVO).MethodsSubjects were selected from the ANGEL-ACT Registry. PH was diagnosed according to the European Collaborative Acute Stroke Study classification. Logistic regression analyses were performed to determine the independent predictors of PH, as well as the association between PH and 90-day functional outcome assessed by modified Rankin Scale (mRS) score.ResultsOf the 1227 enrolled patients, 147 (12.0%) were diagnosed with PH within 12–36 hours after EVT. On multivariable analysis, low admission Alberta Stroke Program Early CT score (ASPECTS)(adjusted OR (aOR)=1.13, 95% CI 1.02 to 1.26, p=0.020), serum glucose >7 mmol/L (aOR=1.82, 95% CI 1.16 to 2.84, p=0.009), and neutrophil-to-lymphocyte ratio (NLR; aOR=1.05, 95% CI 1.02 to 1.09, p=0.005) were associated with a high risk of PH, while underlying intracranial atherosclerotic stenosis (ICAS; aOR=0.42, 95% CI 0.22 to 0.81, p=0.009) and intracranial angioplasty/stenting (aOR=0.37, 95% CI 0.15 to 0.93, p=0.035) were associated with a low risk of PH. Furthermore, patients with PH were associated with a shift towards to worse functional outcome (mRS score 4 vs 3, adjusted common OR (acOR)=2.27, 95% CI 1.53 to 3.38, p<0.001).ConclusionsIn Chinese patients with AIS caused by anterior circulation LVO, the risk of PH was positively associated with low admission ASPECTS, serum glucose >7 mmol/L, and NLR, but negatively related to underlying ICAS and intracranial angioplasty/stenting.Trial registration numberNCT03370939.

Abstract Background: Elevated level of plasma D-dimer increases the risk of ischemic stroke, stroke severity and progression of stroke status, but the association between plasma D-dimer level and functional outcome is unclear. The aim of this study is to investigate whether Plasma D-dimer level is a determinant of short-term poor functional outcome in patients with acute ischemic stroke (AIS). Methods: This prospective study included 877 Chinese patients with AIS admitted to Renmin Hospital of Wuhan University within 72 hours of symptom onset. Patients were categorized per plasma D-dimer level: Quartile 1(0.24 mg /L), Quartile 2 (0.25–0.56 mg /L), Quartile 3 (0.57–1.78 mg /L), and Quartile 4 (1.78mg /L). Each patient’s medical record was reviewed, and demographic, clinical, laboratory and neuroimaging information was abstracted. Functional outcome at 90 days was assessed with the modified Rankin Scale (mRS). Results: Of 877 patients were included (mean age, 64 years; male, 68.5%), poor outcome was present in 302 (34.4%) patients. After adjustment for potential confounding variables, higher plasma D-dimer level on admission was associated with poor outcome (adjusted odds ratio [aOR] 2.257, 95% CI1.349-3.777 for Q4:Q1; P trend = 0.004). According to receiver operating characteristic (ROC) analysis, the best discriminating factor was a plasma D-dimer level 0.315 mg/L for pour outcome [area under the ROC curve (AUC) 0.657; sensitivity 83.8%; specificity 41.4%]. Conclusion: Elevated plasma D-dimer level on admission was significantly associated with increased poor outcome after admission for AIS, suggesting the potential role of plasma D-dimer as a predictive marker for short-term poor outcome in patients with AIS.

Background and purposePrevious studies have reported conflicting results as to whether women have poorer functional outcome than men after thrombolytic therapy. This study aims to investigate the relationship between sex differences and the prognosis of intravenous thrombolysis in Chinese patients with acute ischaemic stroke.MethodsThe patients enrolled in this study were from the Chinese Acute Ischemic Stroke Thrombolysis Monitoring and Registration study. The primary outcome was poor functional outcome, defined as a 3-month modified Rankin score of 3–6. The safe outcome was symptomatic intracranial haemorrhage (SICH) and mortality within 7 days and 90 days. Multiple Cox regression model was used to correct the potential covariates to evaluate the association between sex disparities and prognosis. Furthermore, the interaction of preonset Rankin scores, baseline National Institute of Health Stroke Scale (NIHSS) scores and Trial of Org 10172 in Acute Stroke Treatment (TOAST) types was statistically analysed.ResultsA total of 1440 patients were recruited, including 541 women and 899 men. The baseline information indicated that women were older at the time of onset (66.2±11.2 years vs 61.0±11.3 years, p<0.001), and more likely to have a history of atrial fibrillation (25.3% vs 11.2%, p<0.001), and had a higher NIHSS score on admission (12.3±6.8 vs 11.6±6.7, p=0.04). According to the prognosis analysis of unsatisfactory functional recovery, there was no significant difference between women and men (45.9% vs 37.1%; adjusted OR 1.01, 95% CI 0.75 to 1.37). As for the safe outcome, the proportion of SICH and mortality in women is relatively high but did not reach statistical significance. There was no significant interaction with sex, age, preonset Rankin score, NIHSS score, TOAST classification and the prognosis of intravenous thrombolysis.ConclusionsFor Chinese patients with ischaemic stroke, although women are older and more severe at the time of onset, the prognosis after intravenous thrombolysis is not significantly different from men.

Abstract Background The precise timings of evoked potentials in evaluating the functional outcome of stroke have remained indistinct. Few studies in the Indian context have studied the outcome of early prognosis of stroke utilizing evoked potentials. Objective The aim of this study was to determine somatosensory evoked potentials (SSEPs) and brain stem auditory evoked potentials (BAEPs), their timing and abnormalities in acute ischemic stroke involving the middle cerebral artery (MCA) territory and to correlate SSEP and BAEP with the functional outcome (National Institutes of Health Stroke Scale (NIHSS), modified Rankin scale (mRS) and Barthel’s index) at 3 months. Methods MCA territory involved acute ischemic stroke patients (n = 30) presenting consecutively to the hospital within 3 days of symptoms onset were included. Details about clinical symptoms, neurological examination, treatment, NIHSS score, mRS scores were collected at the time of admission. All patients underwent imaging of the brain and were subjected to SSEP and BAEP on two occasions, first at 1 to 3 days and second at 4 to 7 days from the onset of stroke. At 3 months of follow-up, NIHSS, mRS, and Barthel’s index were recorded. Results P37 and N20 amplitude had a strong negative correlation (at 1–3 and 4–7 days) with NIHSS at admission, NIHSS at 3 months, mRS at admission, and mRS at 3 months and a significant positive correlation with Barthel’s index (p < 0.0001). BAEP wave V had a negative correlation (at 1–3 and 4–7 days) with NIHSS at admission, NIHSS at 3 months, mRS at admission, and mRS at 3 months and a positive correlation with Barthel’s index (p < 0.0001). Conclusion SSEP abnormalities recorded on days 4 to 7 from onset of stroke are more significant than those recorded within 1 to 3 days of onset of stroke; hence, the timing of 4 to 7 days after stroke onset can be considered as better for predicting functional outcome.

Abstract Background It has been shown that eosinophils are decreased and monocytes are elevated in patients with acute ischemic stroke (AIS), but the impact of eosinophil-to-monocyte ratio (EMR) on clinical outcomes among AIS patients remains unclear. We aimed to determine the relationship between EMR on admission and 3-month poor functional outcome in AIS patients. Methods A total of 521 consecutive patients admitted to our hospital within 24 h after onset of AIS were prospectively enrolled and categorized in terms of quartiles of EMR on admission between August 2016 and September 2018. The endpoint was the poor outcome defined as modified Rankin Scale score of 3 to 6 at month 3 after admission. Results As EMR decreased, the risk of poor outcome increased (p < 0.001). Logistic regression analysis revealed that EMR was independently associated with poor outcome after adjusting potential confounders (odds ratio, 0.09; 95% CI 0.03–0.34; p = 0.0003), which is consistent with the result of EMR (quartile) as a categorical variable (odds ratio, 0.23; 95% CI 0.10–0.52; ptrend < 0.0001). A non-linear relationship was detected between EMR and poor outcome, whose point was 0.28. Subgroup analyses further confirmed these associations. The addition of EMR to conventional risk factors improved the predictive power for poor outcome (net reclassification improvement: 2.61%, p = 0.382; integrated discrimination improvement: 2.41%, p < 0.001). Conclusions EMR on admission was independently correlated with poor outcome in AIS patients, suggesting that EMR may be a potential prognostic biomarker for AIS.

Introduction: Pre-stroke dementia is significantly associated with poor stroke outcome. Cholinesterase inhibitors (ChEIs) might reduce the risk of stroke in patients with dementia. However, the association between pre-stroke ChEI treatment and stroke outcome remains unresolved. Therefore, we aimed to determine this association in patients with acute ischemic stroke and pre-stroke dementia. Methods: We enrolled 805 patients with pre-stroke dementia among 13,167 with ischemic stroke within 7 days of onset who were registered in the Fukuoka Stroke Registry between June 2007 and May 2019 and were independent in basic activities of daily living (ADLs) before admission. Primary and secondary study outcomes were poor functional outcome (modified Rankin Scale [mRS] score: 3–6) at 3 months after stroke onset and neurological deterioration (≥2-point increase in the NIH Stroke Scale [NIHSS] during hospitalization), respectively. Logistic regression analysis was used to evaluate associations between pre-stroke ChEI treatment and study outcomes. To improve covariate imbalance, we further conducted a propensity score (PS)-matched cohort study. Results: Among the participants, 212 (26.3%) had pre-stroke ChEI treatment. Treatment was negatively associated with poor functional outcome (odds ratio: 0.68 [95% confidence interval: 0.46–0.99]) and neurological deterioration (0.52 [0.31–0.88]) after adjusting for potential confounding factors. In the PS-matched cohort study, the same trends were observed between pre-stroke ChEI treatment and poor functional outcome (0.61 [0.40–0.92]) and between the treatment and neurological deterioration (0.47 [0.25–0.86]). Conclusions: Our findings suggest that pre-stroke ChEI treatment is associated with reduced risks for poor functional outcome and neurological deterioration after acute ischemic stroke in patients with pre-stroke dementia who are independent in basic ADLs before the onset of stroke.
