Purpose: The aim of the study was to identify the risk factors for seizures in patients with ischemic stroke using clinical, functional, neuroimaging research methods. Materials and methods: The results of the complex survey of 468 patients suffering from ischemic stroke (256 patients experienced epileptic seizures and 203 experienced no epileptic seizures) are presented. The diagnostic procedures included clinical evaluation, magnetic resonance imaging, electroencephalography, extracranial and transcranial Doppler sonography. In addition the assessment of the rate of sodium lithium countertransport (the marker of genetically determined on transport mechanisms of cell membranes) in patients with c ischemic stroke with the development of epileptic seizures and no seizures was carried out. Results: The focal seizures are the most common (92,5%). Cortical ischemic brain lesions prevailed in patients with seizures (81,1%), whereas in the control group cortex was affected in 38,9% patients (χ2=89.2, <0,001). Stenosis of cerebral arteries was more common in patients with epilepsy (82.3%) compared to patients without seizures (74.4%, <0.05). Reduced cerebrovascular reactivity (CVR) in vertebro-basilar basin was more frequently detected in patients with seizures (85.9%, p<0.001) compared to controls (71.6%). CVR < 10% was registered in 33.8% patients with seizures versus 13.4% controls (p<0.001). Patients with epileptic seizures showed cerebral perfusion reduction mostly in vertebro-basilar basin (85.9%) rather than in carotid basin (61.2%, p<0.001). Patients experienced epileptic seizures had high rates of sodium-lithium antitransport (> 346 μmol/liter cells x hour) more often than patients without epileptic seizures (52,6% and 35,5%, respectively, <0,05). Patients experienced epileptic seizures with high rates of sodium-lithium antitransport had a higher seizure frequency than patients with low rates of sodium-lithium antitransport. Conclusion: Thus, cortical ischemic brain lesions, significant stenosis of cerebral arteries, predominant perfusion reserve reduction in the posterior cerebral circulation, as well as a high rate of sodium lithium countertransport may be considered as risk factors for post-stroke epilepsy.

Background: A considerable proportion of acute noncardiogenic ischemic stroke patients continue to experience recurrent ischemic events after standard therapy. Aim: We aimed to identify risk factors for recurrent ischemic event prediction at an early stage. Methods : 286 non-cardioembolic ischemic stroke patients with the onset of symptoms within 24 hours were enrolled. Vascular risk factors, routine laboratory data on admission, thromboelastography test seven days after clopidogrel therapy and any recurrent events within one year were assessed. Patients were divided into case group (patients with clinical adverse events, including ischemic stokes, transient ischemic attack, myocardial infarction and vascular related mortality) and control group (events-free patients). The risk of the recurrent ischemic events was determined by the receiver operating characteristic curve and multivariable logistic regression analysis. Results: Clinical adverse events were observed in 43 patients (case group). The mean levels of Mean Platelet Volume (MPV), Platelet/Lymphocyte Ratio (PLR), Lymphocyte Count (LY) and Fibrinogen (Fib) on admission were significantly higher in the case group as compared to the control group (P<0.001). Seven days after clopidogrel therapy, the ADP-induced platelet inhibition rate (ADP%) level was lower in the case group, while the Maximum Amplitude (MA) level was higher in the case group as compared to the control group (P<0.01). The Area Under the Curve (AUC) of receiver operating characteristic(ROC) curve of LY, PLR, , Fib, MA, ADP% and MPV were 0.602, 0.614, 0.629, 0.770, 0.800 and 0.808, respectively. The logistic regression analysis showed that MPV, ADP% and MA were indeed predictive factors. Conclusion: MPV, ADP% and MA were risk factors of recurrent ischemic events after acute noncardiogenic ischemic stroke. Urgent assessment and individual drug therapy should be offered to these patients as soon as possible.

Abstract Background Whether antiplatelet agents have a preventive effect on cognitive function after ischemic stroke remains unknown. This study examined the potential effect of cilostazol, an antiplatelet agent and cyclic adenosine monophosphate phosphodiesterase 3 inhibitor, on cognitive impairment after stroke in an Asian population. Methods A total of 45 patients using cilostazol (100 mg) twice per day were enrolled as the study group and 45 patients using aspirin (100 mg) or clopidogrel (75 mg) daily were enrolled as the control group. Mini-mental state examination and Cognitive Assessment Screening Instrument were administered at the start of the study and after 6 months. Multiple logistic regression analysis was used to estimate the association between the cognitive change and cilostazol use. Results Overall, 60-70% of the patients improved their cognition after 6 months follow up. No significant differences were observed in the cognitive change between the cilostazol and control groups. However, the cilostazol group appeared to perform better in the fluency, language and judgment subdomains. Conclusions In the current study, the clinical course of post stroke cognitive changes was described. Although cilostazol did not make a significant difference in cognitive change after ischemic stroke, it may improve fluency, language and judgment subdomains. These findings should be examined further in randomized clinical trials.

Introduction: TCD emboli monitoring (TCDe) is a non-invasive tool used to detect the presence of ongoing microembolic signals (MES) in the intracranial arterial vessels. The clinical utility of this test in the evaluation of acute stroke patients has been debated. Our goal was to evaluate clinical factors associated with MES in ischemic stroke patients who underwent TCDe to determine which patient population may benefit from TCDe. Methods: Retrospective cohort study of adult patients admitted to our tertiary care center for TIA or ischemic stroke from 2011 to 2012 who underwent TCDe. Monitoring was performed for 20 minutes using a standardized protocol. Inclusion criteria included insonatation of both middle cerebral arteries and completion of TCD bubble study (TCB). Repeat TCDe performed on the same patient were excluded from the analysis. Demographic, clinical and objective data were collected using our EMR system. Results: Of the 113 patients included in the final analysis, mean age was 57.9 years and 46.9% were female. MES occurred in 33.6% patients. Mean # of MES was 9.3 (SD 60.6). Patients with MES were significantly younger (51.8 years vs 61.0, p.006) and had fewer vascular risk factors: diabetes (10.5% vs 33.3%, p 0.006), hyperlipidemia (23.7% vs 49.3%, p 0.007), hypertension (47.4% vs 17.33%, p 0.067), atrial fibrillation (7.9% vs 17.33 %, p 0.16), congestive heart failure (5.3% vs 10.7%, p 0.32) and coronary artery disease (18.4 % vs 29.3%, p 0.2). Cryptogenic stroke and the presence of right to left shunt (RLS) was more frequent in patients with MES than those without. Mean WBC count and usCRP were both nonsignificantly higher in patients with MES. Conclusions: Clinical characteristics of patients with MES on TCDe differed from those without MES, which may have diagnostic and clinical implications. Patients with MES were younger and had fewer stroke risk factors. MES were seen more often in patients with RLS and in those with cryptogenic stroke, which raises the possibility of an association between these two factors. Interestingly, patients with MES also had higher usCRP and WBC values, suggesting a possible inflammatory component to the occurrence of MES. More research is needed with a larger sample size to better define the significance of the above findings.

Background: Interleukin-37 (IL-37) is a new member of IL-1 cytokine family with a defined role as a negative feedback inhibitor of pro-inflammatory responses. IL-37 has yet to be evaluated in non-immune neurological diseases like ischemic or hemorrhagic stroke. This study aimed to measure the urine and serum IL-37 levels in patients with acute ischemic stroke. Method: Twelve patients consented for the study. Two sets of serum and urine samples were obtained and analyzed; one upon admission to the hospital, and the second the next morning after overnight fasting. The trends in serum level of IL-37 in 5 stroke patients, while trends in urine level of 6 patients were available, measured by real-time polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA). Prior studies with healthy volunteers as control group have consistently showed IL-37 plasma level around or less than 65 pg/ml with maximum normal levels on ELISA approximated at 130 pg/ml. Results: IL-37 level in urine in stroke patients ranged from 297 - 4467. IL-37 levels were in the range of 300s to 1000s in patients with ischemic stroke compared with reported healthy controls in literature where the level was always less than 90. Three of these 10 patients presented within 3 hours of stroke onset with IL-37 serum levels being 2655 pg/ml, 3517 pg/ml and 5235 pg/ml. In all others, it ranged much less than that, with the trend of delayed presentation giving less IL-37 levels, both in urine and serum. There were no clear differences found in patients with or without tPA, diabetes, hyperlipidemia and high blood pressure in our small study. Conclusion: The study shows a rather stable elevation of IL-37 levels post-ischemic stroke, which if compared to available data from other studies, is 3-10 times elevated after acute ischemic stroke with an uptrend in the first few days. IL-37 plays some role in mediating post-stroke inflammation with significant rise in serum and urine IL-37 levels suggesting a key role of this novel cytokine in post-stroke pathology. This is the first ever reported study measuring and trending IL-37 levels in human plasma after an acute ischemic stroke.

Background: Although SSRI use for ischemic stroke related motor recovery has been studied with mixed results, the effects of the pre-existing psychotropic medication use (PPMU), such as antidepressants, on a long-term ischemic stroke outcome is unknown. Objective: We sought to determine the prevalence of PPMU, and the clinical outcome in a cohort of patients presenting with acute ischemic strokes. Methods: We retrospectively analyzed 323 consecutive patients who presented with an acute ischemic stroke that were included in an institutional stroke registry between January 2015 and December 2017. Baseline characteristics, functional outcome measured by mRS, cardiovascular complications and death within 90 days and 365 days were recorded. The control was defined as a group of ischemic stroke patients that were not on psychotropic medications pre- and/or post-ischemic stroke. Results: The prevalence of PPMU in the studied cohort was 21.4% (69/323). The prevalence of female gender in PPMU was higher compared to the control and post stroke-psychotropic medication use groups (P<0.001), and the patients with PPMU had similar vascular risk factors compared to the control (NS), except for an increased presence of hyperlipidemia (68.1% vs. 57.5%, p<0.05). Among the patients with an available 90-day follow-up (n=175) and 365-day follow-up (n=246), there was no statistically significant difference in outcome events of MI, stroke, death, and dementia. The mRS was higher on PPMU and poststroke-psychotropic medication use groups compared to the control group within the 365-day follow-up (P=0.013). Conclusion: The prevalence of PPMU is common in ischemic stroke, and it is not associated with worsened post-stroke complications within 1 year.

IntroductionVarious neurological complications may occur as a consequence of arterial ischemic stroke (AIS) and have an impact on daily activity of the patients, costs of their medical care and rehabilitation. The aim of this study was to analyze risk factors, stroke symptoms and post-stroke consequences in Polish pediatric patients depending on stroke subtype.Material and methodsWe retrospectively reviewed 77 children under the age of 18 years following their first AIS. Patients were white, Polish Caucasians, recruited in the Department of Pediatric Neurology at the Medical University of Silesia in Katowice (Poland). Statistical analysis was performed using Statistica 12.0.ResultsGender differed significantly between stroke subgroups (p = 0.030). The presence of focal cerebral arteriopathy (FCA) and chronic diseases was associated with type of AIS (p = 0.003 and p = 0.050, respectively). An outcome without neurological deterioration (normal outcome) was observed in 43% of children with lacunar anterior circulation infarct (LACI). Hemiparesis was present in almost all children with total anterior circulation infarct (TACI), in two thirds of children with partial anterior circulation infarct (PACI) and in almost 50% of children with LACI or posterior circulation infarct (POCI). In every child with hemiplegia the stroke symptom evolved into hemiparesis at follow-up. Additionally, patients with a normal outcome were older at the time of AIS than those with at least one neurological consequence (OR = 0.894, p = 0.034).ConclusionsThe presence and number of neurological outcomes depend on stroke subtypes. A relation between the presence of post-stroke deficits and age at onset was observed. The odds of deficit after ischemic stroke decreases by an average of 10.6% if the child is 1 year older at the time of AIS.

Post Stroke Depression

Background: There are several factors that contribute to Post Stroke Depression (PSD). Since a single intervention is proven ineffective to deal with PSD, an intervention which includes biological, psychological, social, and spiritual aspects (“SELF-HELP Packages”), therefore, needs to be established.Purpose: The purpose of the study was to investigate the effect of “SELF HELP Packages” intervention on PSD among ischemic stroke survivors after three months from onset and its effect after confounding variables were controlled.Methods: This study was a pre and post quasi-experiment with a control group involving 34 ischemic stroke survivors each group. The inclusion criteria were survivors after three months from ischemic stroke, no aphasia, having a good hearing, and having Mini Mental Status Examination (MMSE) score of ≥ 22. GRID-HAMD 17, Multidimensional Scale of Perceived Social Support (MSPSS), and Barthel-Index were used to measure PSD, social support, and functional status respectively. “SELF-HELP Packages” intervention was delivered in three sessions, namely information delivery, discussion and activity. Statistical analyses were conducted using McNemar test, Chi-square and logistic regression.Results: The result showed that “SELF-HELP Packages” considerably decreased PSD in the intervention group (p=0.004). There were also significant differences in PSD after the intervention between two groups (p=0.008). Logistic regression showed that ‘SELF-HELP Package” had no effect on PSD when other confounding variables were controlled (p=0.075, OR=0.288, 95% CI 0.073 – 1.135).Conclusion: SELF-HELP Packages” should be applied in providing the nursing intervention among stroke ischemic survivors in clinical setting. A longer period of time for the intervention is also recommended for the next study in order to obtain a more robust result.

According to epidemiological data, stroke’s incidence is clearly growing, especially in young people under 45. Ischemic stroke is the most common type (80%). Many risk factors have been identified, including hypertension, tobacco, dyslipidemia, diabetes, alcohol, and oestroprogestogenic contraceptive pill. The main mechanisms are atheroma of large arterial trunks, occlusion of small cerebral arteries unrelated to atherosclerosis, and cardio-embolic causes. The aim of our study is to present a clinical case of ischemic stroke in young subjects caused by heart disease at high embolic risk.
