Objective:The aim of this retrospective study was to investigate if elevated C reactive protein (CRP) was related to the stroke severity, and to analyze its different distribution in stroke subtypes.Methods:316 patients with acute ischemic stroke (AIS) were enrolled and had CRP determinations; they were dichotomized as<7 or ≥7mg/L according to the previous report. 128 patients with transient ischemic attack who also had CRP measurements were selected as controls. A possible level-risk relationship between elevated CRP and NIHSS, which considered relatively severe illness as a value≥8, was studied within the AIS group.Results:CRP was elevated in 21% of the AIS compared to 4% in the control group (p = 0.000). Within the AIS group, patients with CRP levels ≥7mg/L had a significantly increased risk of severe stroke (OR 3.33, 95% CI 1.84-6.00, p =0.00). In subtype stroke, the highest rate of elevated CRP and NIHSS were in those with cardioembolic stroke (CE) using TOAST classification, total anterior circulation infarction (TACI) of OCSP classification and large volume infarction (LVI) of Adams classification; the odds ratio(OR) between elevated CRP and NIHSS was 6.14 (95% CI 1.43-26.44) in CE, 1.714 (95% CI 1.30-2.26) in TACI, 2.32 (95% CI 1.08-4.99) in LVI, and the p value were all below 0.05.Conclusion:Elevated CRP level can reflect the severity of AIS, which was association with stroke subtype.

ABSTRACT. Various mechanisms contribute to dementia after first ischemic stroke as lesions on strategic areas of cognition and stroke premorbidity. Objectives: Assessing clinical and neuroimaging predictors of dementia after first ischemic stroke and its relation to stroke location, subtypes and severity. Methods: Eighty first ischemic stroke patients were included. Forty patients with dementia after first stroke and forty patients without dementia according to DSM-IV diagnostic criteria of vascular dementia. All patients were subjected to general and neurological assessment, National Institute Health Stroke Scale (NIHSS) for stroke severity, Montreal Cognitive Assessment (MoCA) scale for cognition assessment, MRI brain and Trial of Org 10172 in acute stroke treatment (TOAST) classification for stroke subtypes. Results: Left hemispheric ischemic stroke, strategic infarctions, diabetes mellitus and stroke of anterior circulation were found to be independent risk factors for dementia after first ischemic stroke (OR=3.09, 95%CI 1.67-10.3, OR=2.33, 95%CI 1.87-8.77, OR=1.88, 95%CI 1.44-4.55, OR=1.86, 95%CI 1.45-6.54, respectively). Hypertension, dyslipidemia, smoking, ischemic heart disease, high NIHSS score and large vessel infarction were significantly higher among post stroke dementia patients. However, on binary logistic regression, they did not reach to be independent risk factors. Conclusion: Stroke location (left stroke, strategic infarction, anterior circulation stroke) and diabetes mellitus could be predictors of dementia after first ischemic stroke, but stroke severity, stroke subtypes, hypertension, dyslipidemia, smoking and ischemic heart could not.

The aim of this study is to investigate the differences in hemostasiological parameters among patients with atherotrombotic and cardiemobolic subtypes of ischemic stroke and the relationship between the parameters and the severity of the disease in the first day. The study included 68 patients who were examined on the first day of the disease with a diagnosis of acute cerebrovascular disorders on ischemic type, among them 47 (69%) men and 21 (31%) women aged from 42 to 75 years (the average age was 61,85 ± 2,33 years old). We quantified the stroke severity by using the National Institutes of Health Stroke Scale, findings of magnetic resonance tomography and / or computer tomography of the brain; ultrasound scan of intra- and extracranial vessels of the brain was performed to verify the diagnosis. Patients were divided into 2 groups: Group 1 included atherotrombotic subtype of ischemic stroke (n = 51 individuals), group 2 included cardiembolic subtype of ischemic stroke (n = 17 individuals. The state of the hemostasis system was studied by the analysis of complete coagulograms. The patients with ischemic stroke were found to have a thrombin time reduction compared to the control group. The dynamics of this indicator in the coagulogram points out an increased risk of thrombosis in the patients of both groups with a significant predominance among the patients with an atherotrombotic stroke. In both groups of the patients with ischemic stroke, there was a decrease in intensity, time and rate of aggregation in 30 seconds compared to the control group, indicating the imbalance of platelet response to adenosine diphosphate-induced aggregation. When the rate and intensity of aggregation (the lowering of platelet aggregation function) for 30 seconds decreased, the aggregation time (the activation of platelet function) also reduced. The analysis of coagulogram indicators points out the possibility of developing the syndrome of disseminated intravascular coagulation among patients with ischemic stroke. In this case, the decrease in the platelet aggregation properties indicates the development of thrombocytopathy under a preserved platelet number among the patients with ischemic stroke. The degree of the severity of atherotrombotic ischemic stroke is associated with indicators of coagulation hemostasis and platelet aggregation characteristics. The severity of cardioembolic ischemic stroke is associated with processes of platelet aggregation processes.

Arterial ischemic stroke (AIS) in childhood is reported to occur more frequently in boys, which may lead to the assumption that the prevalence of post-stroke deficits is sex related. The present study aimed to evaluate sex-related differences in functional outcomes (hemiparesis, seizures, aphasia, and motor disturbances other than hemiparesis) in pediatric patients with AIS. A total of 89 children (52 boys and 37 girls; mean age at stroke onset: 8.4 ± 5.6 years) were evaluated retrospectively based on data from medical records. The patients were divided into subgroups according to age (i.e., infants and toddlers, children, and adolescents), stroke subtype (i.e., lacunar anterior circulation infarct (LACI), total anterior circulation infarct (TACI), partial anterior circulation infarct (PACI), posterior circulation infarct (POCI)) and stroke location (i.e., anterior stroke, posterior stroke). Significant differences in the prevalence of stroke subtypes between girls and boys were observed (p = 0.034). POCI stroke were found to be more frequent in boys than in girls (OR = 8.57 95%CI 1.05–70.23, p = 0.023). Males predominated in the total group and in all analyzed age subgroups. The proportions of boys within the subgroups according to stroke subtype were extremely high for the POCI and TACI stroke subgroups. On the other hand, girls predominated in the LACI stroke subgroup. Frequency of central type facial nerve palsy and other symptoms of AIS were found to significantly differ between male subgroups according to stroke subtype (p = 0.050 and p < 0.001, respectively), as well as between children with anterior stroke and those with posterior stroke (p = 0.059 and p < 0.001, respectively). Post-stroke seizures appeared significantly more commonly in girls with TACI and POCI stroke than in girls with LACI and PACI stroke (p = 0.022). In turn, the prevalence of post-stroke hemiparesis differed between stroke subtypes in boys (p = 0.026). In conclusion, sex may have an impact in predisposing to a certain type of AIS in the patient. Post-stroke seizure may be related to stroke subtype in girls and hemiparesis in boys. However, further studies are needed to confirm the results.

A recent study of the ischemic stroke described the roles played by miRNAs in the downregulation of specific cell-cycle gene expression and it is thought to require the development of biomarkers for the prognostic of ischemic stroke. Here, we hypothesized that four miRNA polymorphisms (miR-10a, miR-27a, miR-34b/c, and miR-300) may affect stroke susceptibility and mortality. Blood samples were collected from 530 patients and 403 controls. Genetic polymorphisms were detected by polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis and real-time PCR. We found that the miR-300 rs12894467 TC genotype and the dominant model (AOR: 2.069, p-value: 0.017; AOR: 1.931, p-value: 0.027) were significantly associated with an increased risk for the ischemic stroke subtype. In Cox proportional hazard regression models, the miR-10a rs3809783 A>T and miR-34b/c rs4938723 T>C polymorphisms were associated with the mortality rates among ischemic stroke patients. We found that a miR-300 polymorphism was associated with increased ischemic stroke susceptibility among the Korean population. Additionally, polymorphisms in miR-10a and miR-34b/c were associated with the increased or decreased mortality of ischemic stroke patients. This study marks the first report of an association between ischemic stroke and miRNA polymorphisms (miR-10aA>T, miR-27aT>C, miR-34b/cT>C, and miR-300T>C) in the Korean population.

Background: Renal dysfunction (RD) may be associated with poor outcome in ischemic stroke patients treated with mechanical thrombectomy (MT), but data concerning this important and emerging comorbidity do not exist so far. Here, we investigated the influence of RD on postprocedural intracerebral hemorrhage (ICH), clinical outcome, and mortality in a large prospectively collected cohort of acute ischemic stroke patients treated with MT. Methods: Consecutive patients with anterior-circulation stroke treated with MT between October 2010 and January 2016 were included. RD was defined as glomerular filtration rate (GFR) <60 mL/min/1.73 m2. In a prospective database, clinical characteristics were recorded and brain images were analyzed for the presence of ICH after treatment in all patients. Clinical outcome was assessed by the modified Rankin Scale (mRS) after 3 months. To evaluate associations between clinical factors and outcomes uni- and multivariate regression analyses were conducted. Results: In total, 505 patients fulfilled all inclusion criteria (female: 49.7%, mean age: 71.0 years). RD at admission was present in 20.2%. RD patients were older and had cardiovascular risk factors more often. Multivariate regression analysis after adjustment for age, stroke severity, diabetes, hypertension, GFR, previous stroke, MT alone, or additional thrombolysis and recanalization results revealed that lower GFR was not independently associated with poor outcome (mRS 3-6; OR 1.13, 95% CI 0.99-1.28; p = 0.072) or ICH. However, lower GFR at admission was associated with a higher risk of mortality (OR 1.15, 95% CI 1.01-1.31; p = 0.038). Compared to admission, GFR values were higher at discharge (mean: 77.9 vs. 80.8 mL/min/1.73 m2; p = 0.046). Conclusions: We did not find evidence for an association of lower GFR with an increased risk of poor outcome and ICH, but lower GFR was a determinant of 90-day mortality after endovascular stroke treatment. Our findings encourage also performing MT in this relevant subgroup of acute ischemic stroke patients.

Objectives: Identifying underlying stroke etiology plays critical role in acute management and secondary prevention strategies. Despite advanced diagnostics, up to 35% of ischemic strokes (IS) remain undetermined. We sought to evaluate the association between IS subtypes and plasma levels of biomarkers as representative of distinct etiologies underlying stroke subtypes. Methods: We prospectively measured plasma high sensitivity-C reactive protein (hs-CRP), matrix metalloproteinase (MMP)-2 and MMP-9, F2-isoprostane (F2-isoP), Oxygen Radical Absorbance Capacity assay (ORAC), homocysteine and urinary 8-hydroxydeoxyguanosine (8OHdG), in patients presenting within 9 hours from acute ischemic stroke (AIS) onset. Stroke subtype was assigned by a stroke neurologist according to the Causative Classification of Stroke System (CCSS) criteria. Results: There were 489 AIS subjects enrolled in this study [mean (SD) age 70.1 (15.1) y; 43.4% female; median (IQR) NIHSS 6 (3-13); 40.7% received IV tPA]. Among these AIS, 51% were of cardioembolic (CE), 17% of atherothrombotic, 7% of lacunar, 5% of other, and 20% of undetermined subtype. Patients with CE stroke were older and more likely to be female, non-smokers, have atrial fibrillation and congestive heart failure, but not carotid stenosis (all p<0.05). CE stroke subtype was also associated with greater stroke severity, and baseline levels of MMP-2 (p= 0.001) and ORAC (p= 0.008), as compared to other CCSS subtypes. In multivariate logistic regression analysis including all univariate predictors with p<0.05 as well as treatment with IV t-PA, baseline MMP-2 (OR 2.8, 95% CI 1.3-5.8; p= 0.006) and ORAC (OR 2.6, 95% CI 1.3-5.1; p= 0.007) was independently associated with CE stroke subtype. Conversely, the “other” stroke subtype was associated with lower levels of MMP-2 (OR 0.1, 95% CI 0.02-0.3; p= 0.001), and homocysteine levels were independently correlated with undetermined subtype (OR 2.2, 95% CI 1.2-4.1; p= 0.008). Conclusions: In AIS patients, hyperacute plasma biomarkers are associated with specific stroke subtypes, reflective of the underlying pathophysiology. If validated in future studies, plasma biomarkers may play valuable role in early diagnosis and guide management of specific AIS subtypes.

Background and Purpose: Calcification of the intracranial carotid artery is recognized as a risk factor for stroke in the general population. The significance of vascular calcifications in its relationship stroke mechanisms is incompletely understood. We hypothesized that vascular calcium quantification using CT angiography (CTA) can differ by stroke mechanism among ischemic stroke patients. Methods: From a prospective single-hospital stroke registry from 2018, we identified ischemic stroke patients who underwent CTA. Automatic artery and calcification segmentation method measured calcification volumes in the intracranial, extracranial, and aortic arteries using deep-learning U-net model and region-grow algorithms. Stroke subtypes were diagnosed based on the TOAST classification: large artery atherosclerosis (LAA), small vessel occlusion (SVO), cardioembolism (CE), others/undetermined. We evaluated the relationship between CTA calcification volume and stroke subtypes on one-way ANOVA and Tukey’s post-hoc test. Results: Of the 558 consecutive acute ischemic stroke patients, we enrolled 388 patients (212 males; mean age 66.6 years) in the study. Others/undetermined (34.8%) was the most frequent stroke subtype, followed by CE (29.4%), LAA (25.5%), and SVO (10.3%). The overall prevalence of atherosclerotic calcification was 95.9% in stroke patients. LAA had significantly higher calcification volume with 809 mm 3 compared to SVO (390 mm 3 , P=0.040), others/undetermined (300 mm 3 , P=0.001), but not CE (860 mm 3 , P=0.958). In age < 65 years subset, LAA showed higher calcification volume with 567 mm 3 than SVO (176 mm 3 , P=0.014), CE (213 mm 3 , P=0.021) and others/undetermined (180 mm 3 , P<0.001). There were no significant differences in calcification volume among stroke subtypes in age ≥65 years. Conclusion: Atherosclerotic calcium burden with a quantitative analysis of CTA images may be useful to differentiate stroke mechanism in younger patients.

Abstract Background Stroke represents the second leading cause of death in the world after myocardial infarction. Intravenous (IV) thrombolysis with recombinant tissue plasminogen activator (alteplase, rt-PA) is the only pharmacological therapy that was approved for treatment within 4.5 h of acute ischemic stroke (AIS) onset. We aimed to predict the 3-month outcome of AIS patients who received alteplase regarding mortality, spontaneous intra-cerebral hemorrhage (sICH), and functional outcome in comparison with non-thrombolyzed patients and to evaluate the predictors of the outcome after 3 months. Methods All the clinical, National Institute of Health Stroke Scale (NIHSS) scores, radiological, and laboratory data of 40 AIS patients and received rt-PA during the period from 2016 to 2018 were collected and analyzed retrospectively. For comparison, 40 patients, as a control group, were selected to match the alteplase group as regards the baseline data and received regular treatment, rather than rt-PA within the first 24 h, that were obtained. The outcome of the thrombolyzed patients after 3 months was evaluated in comparison with controls by using a modified ranking scale. Results After a 90-day follow-up period, the death rate was slightly higher among the rt-PA group (7.5%) in comparison with the control group (5%). sICH occurred in 7.5% of the patients in the alteplase group and in 5% of the non-thrombolyzed patients; however, this difference was not significant. More patients had a favorable outcome (mRS = 0–2) in the rt-PA group than in the control group (65% vs 60%, OR 1.38, 95% CI 0.50–3.6, P = 0.51). NIHSS score on admission, body mass index (BMI) (≥ 30), and previous transient ischemic attacks (TIA)/previous ischemic stroke were significant predictors of outcome after IV thrombolysis. Age, sex, hypertension (HTN), diabetes mellitus (DM), dyslipidemia, smoking, atrial fibrillation (AF), stroke subtype, size of infarction, and hyperdense middle cerebral artery had a non-significant effect. Conclusion After 3 months of follow-up, rt-PA had a non-significant more increase of favorable outcome with increased risk of sICH and death than controls. Baseline NIHSS, BMI, and history of TIA or previous ischemic stroke were significant predictors of outcome after thrombolysis.

The relation of Zika virus (ZIKV) with microcephaly is well established. However, knowledge is lacking on later developmental outcomes in children with evidence of maternal ZIKV infection during pregnancy born without microcephaly. The objective of this analysis is to investigate the impact of prenatal exposure to ZIKV on neuropsychomotor development in children without microcephaly. We evaluated 274 children including 235 ZIKV exposed and 39 controls using the Bayley-III Scales of Infant and Toddler Development (BSIDIII) and neurological examination. We observed a difference in cognition with a borderline p-value (p = 0.052): 9.4% of exposed children and none of the unexposed control group had mild to moderate delays. The prevalence of delays in the language and motor domains did not differ significantly between ZIKV-exposed and unexposed children (language: 12.3% versus 12.8%; motor: 4.7% versus 2.6%). Notably, neurological examination results were predictive of neurodevelopmental delays in the BSIDIII assessments for exposed children: 46.7% of children with abnormalities on clinical neurological examination presented with delay in contrast to 17.8% among exposed children without apparent neurological abnormalities (p = 0.001). Overall, our findings suggest that relative to their unexposed peers, ZIKV-exposed children without microcephaly are not at considerably increased risk of neurodevelopmental impairment in the first 42 months of life, although a small group of children demonstrated higher frequencies of cognitive delay. It is important to highlight that in the group of exposed children, an abnormal neuroclinical examination may be a predictor of developmental delay. The article contributes to practical guidance and advances our knowledge about congenital Zika.

Abstract Introduction Global longitudinal strain (GLS) via speckle tracking echocardiography (STE) has emerged as a quantitative technique to estimate myocardial function and has been shown to have clinical utility in a variety of settings. The use of this technique in patients with a stroke is limited. Purpose Comparative analysis of myocardial deformation indicators in patients with a stroke, depending on the severity and subtype. Results 230 patients with an acute cerebrovascular accident (132 men and 98 women) were included in our study, with the mean age of 64,9±10,8. Transient ischemic attack (TIA) was diagnosed in 39 (17%), acute ischemic stroke (AIS) in 191 (83%) patients. The type of an ischemic stroke in each patient was classified as one of the following traditional stroke subtypes: large-artery atherosclerosis (LAA) was diagnosed in 85 (44,5%), cardioembolic infarcts were diagnosed in 58 (30,4%), lacunar infarcts were diagnosed in 32 (16,8%) and in 16 (8,4%) the stroke was of another determined or undetermined etiology. There was no significant difference in left ventricular (LV) ejection fraction (EF) between the subgroups of TIA and AIS - 63.0% [60.0; 65.0] and 62.0% [58.0; 65.0], respectively. The LV GLS was within normal limits and amounted to 19.9±2.6 in the TIA group where as in the group of patients with stroke there was a significant (p&lt;0.01) decrease in GLS below standard values - 17.1±3.8. The LV EF showed no significant difference between the groups of stroke subtypes. However, a decrease in GLS was found in the series from cardioembolic infarct &gt; lacunar infarct &gt; LAA - 17.5±3.7 &gt; 16.5±6.5 &gt; 16.2±3.2 (p=0,7). A decrease in GLS was significantly more often observed in male patients. A decrease in the level of GLS in patients with a stroke is associated with duration of type 2 diabetes, stroke severity by the National Institutes of Health Stroke Scale (NIHSS) score, ECG voltage criteria for LVH, increase in heart rate, LV mass/BSA, relative wall thickness (RWT) according to echocardiography. Significant differences in GLS from the size of the stroke focus according to CT scanning/ magnetic resonance imaging were not detected. Conclusion GLS via STE in patients with a stroke correlates with the severity of a stroke, the severity of LV remodeling, risk factors for cardiovascular events and requires a further study to assess the long-term prognosis Funding Acknowledgement Type of funding source: None
