Background and Purpose: Non-convulsive status epilepticus (NCSE) is common in patients with disorders of consciousness and can cause secondary brain injury. Our study aimed to explore the determinants and prognostic significance of NCSE in stroke patients with impaired consciousness.Method: Consecutive ischemic stroke patients with impaired consciousness who were admitted to a neuro intensive care unit were enrolled for this study. Univariate and multivariable logistic regression were used to identify factors associated with NCSE and their correlation with prognosis.Results: Among the 80 patients studied, 20 (25%) died during hospitalization, and 51 (63.75%) had unfavorable outcomes at the 3-month follow-up. A total of 31 patients (38.75%) developed NCSE during 24-h electroencephalogram (EEG) monitoring. Logistic regression revealed that NCSE was significantly associated with an increased risk of death during hospital stay and adverse outcomes at the 3-month follow-up. Patients with stroke involving the cerebral cortex or those who had a severely depressed level of consciousness were more prone to epileptogenesis after stroke.Conclusion: Our results suggest that NCSE is a common complication of ischemic stroke, and is associated with both in-hospital mortality and dependency at the 3-month follow-up. Long-term video EEG monitoring of stroke patients is, therefore required, especially for those with severe consciousness disorders (stupor or coma) or cortical injury.

Background: Cerebral microbleeds (CMBs) were predictive of mortality in elderly and considered as a putative marker for risk of intracranial hemorrhage. Stroke patients with non valvular atrial fibrillation (NVAF) require anticoagulation, which increases the risk of hemorrhages. We investigated association of CMBs with the long term mortality in acute ischemic stroke patients with NVAF. Methods: During 6 years , consecutive ischemic stroke patients who had NVAF and who had undergone brain MRI with a gradient-recalled echo sequence were enrolled. Long-term mortality and causes of death were identified using data from Korean National Statistical Office. Survival analysis was performed whether the presence, number and location of CMBs were related with all causes, cardiovascular, and cerebrovascular mortality during follow-up. Results: Total 506 patients were enrolled during the study period and were followed up for median 2.5 years. CMBs were found in 30.8% of patients (156/506). Oral anticoagulation with warfarin was prescribed at discharge in 477 (82.7%) patients. During follow up, 177 (35%) patients died and cerebrovascular death was noted in 93 patients (81 ischemic stroke and 12 hemorrhagic stroke). After adjusting age, sex and significant variables in univariate analysis (p<0.1), multiple CMBs (≥5) were the independent predictor for all-cause, cardiovascular and ischemic stroke mortalities. The strictly lobar CMBs were associated with hemorrhagic stroke mortality in multivariate Cox regression analysis (HR 4.776, p=0.032) (Figure 1). Conclusions: Multiple CMBs were the independent predictor for the long term mortality in stroke patients with NVAF. Among them, patients with strictly lobar CMBs had a high risk of death due to hemorrhagic stroke. Our findings suggest that detection of CMBs in stroke patients with NVAF are of clinical relevance for predicting long term outcome and that particular concern is necessary in those with strictly lobar CMBs for their increased risk of death due to hemorrhagic stroke.

Objective: This investigation aimed at studying the prevalence of cerebral microbleeds (CMBs), including risk factors and the correlation of CMBs to ischemic stroke (IS) patient end results.Methods: Four hundred and fifty-nine acute IS cases were recruited between April 2014 and December 2016. Cerebral microbleeds were analyzed using susceptibility-weighted imaging (SWI) brain MRI scan. The enrolled patients with acute IS were followed up for 12–24 months, with a median follow-up time of 19 months. The follow-up endpoint events including recurrent ischemic stroke (RIS), intracranial hemorrhage (ICH), transient ischemic attack (TIA), mortality, and cardiovascular events. The associations between vascular risk factors and CMBs in IS patients were analyzed using univariate and multivariate logistic regression analysis. Cox regression model was employed for evaluating CMB impact on clinical outcome.Results: Among 459 enrolled patients, 187 (40.7%) had CMBs and 272 (59.2%) had no CMB. In comparison with patients with no CMBs, age was higher and hypertension was more frequent in patients with CMBs. Multivariate logistic regression analyses revealed age and hypertension were independently associated with the presence of CMBs. Among the patient cohort, 450 cases completed the follow-up. During the follow-up period, 22 (4.9%) of patients developed ICH, 12 (2.7%) developed TIA, 68 (15.1%) developed RIS, cardiovascular events occurred in 20 (4.44%), and 13 (2.89%) cases were mortalities. Compared with patients without CMBs, IS patients with CMBs have an increased prevalence of ICH (p &lt; 0.05). However, no statistically valid variations regarding other outcome incidences between both groups was identified (p &gt; 0.05). The incidence of ICH was elevated in tandem with elevations in number of CMBs. Following adjusting for age, multivariate Cox proportional-hazards regression analysis revealed that CMBs ≥10 were independent predictors of ICH in acute IS patients.Conclusion: Age and hypertension are independently associated with the presence of CMBs. Intracranial hemorrhage incidence rate was increased with the number of CMBs, and the number of CMBs ≥10 were independent predictors of ICH in acute stroke patients.

Stroke represents the second common cause of death in adults. Objective It was to evaluate the incidence and causes of mortality after 30 days in a group of patients with an atherothrombotic ischemic stroke who were followed-up for a period of up to two years. Methods We analyzed retrospectively the medical records of patients with ischemic stroke, who did not undergo thrombolysis, of the Santa Marcelina Hospital. We applied a research protocol to obtain information about risk factors and the etiology of death. Results They were followed 337: mean age was 66.6 years (SD 9.05) and 43.9% were females. The mortality rate was 11.9% with most deaths (37.5%) occurring due to infectious causes. The age was correlated with the risk of death, which was five times higher in patients older than 80. Conclusion The most important cause of death after 30 days was infectious disease, and advanced age was predictor of mortality among patients with an atherothrombotic stroke etiology.

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.

Background: Dysphagia is associated with poor outcome in stroke patients. Studies investigating the association of dysphagia and early dysphagia screening (EDS) with outcomes in patients with acute ischemic stroke (AIS) are rare. The aims of our study are to investigate the association of dysphagia and EDS within 24 h with stroke-related pneumonia and outcomes. Methods: Over a 4.5-year period (starting November 2007), all consecutive AIS patients from 15 hospitals in Schleswig-Holstein, Germany, were prospectively evaluated. The primary outcomes were stroke-related pneumonia during hospitalization, mortality, and disability measured on the modified Rankin Scale ≥2-5, in which 2 indicates an independence/slight disability to 5 severe disability. Results: Of 12,276 patients (mean age 73 ± 13; 49% women), 9,164 patients (74%) underwent dysphagia screening; of these patients, 55, 39, 4.7, and 1.5% of patients had been screened for dysphagia within 3, 3 to <24, 24 to ≤72, and >72 h following admission. Patients who underwent dysphagia screening were likely to be older, more affected on the National Institutes of Health Stroke Scale score, and to have higher rates of neurological symptoms and risk factors than patients who were not screened. A total of 3,083 patients (25.1%; 95% CI 24.4-25.8) had dysphagia. The frequency of dysphagia was higher in patients who had undergone dysphagia screening than in those who had not (30 vs. 11.1%; p < 0.001). During hospitalization (mean 9 days), 1,271 patients (10.2%; 95% CI 9.7-10.8) suffered from stroke-related pneumonia. Patients with dysphagia had a higher rate of pneumonia than those without dysphagia (29.7 vs. 3.7%; p < 0.001). Logistic regression revealed that dysphagia was associated with increased risk of stroke-related pneumonia (OR 3.4; 95% CI 2.8-4.2; p < 0.001), case fatality during hospitalization (OR 2.8; 95% CI 2.1-3.7; p < 0.001) and disability at discharge (OR 2.0; 95% CI 1.6-2.3; p < 0.001). EDS within 24 h of admission appeared to be associated with decreased risk of stroke-related pneumonia (OR 0.68; 95% CI 0.52-0.89; p = 0.006) and disability at discharge (OR 0.60; 95% CI 0.46-0.77; p < 0.001). Furthermore, dysphagia was independently correlated with an increase in mortality (OR 3.2; 95% CI 2.4-4.2; p < 0.001) and disability (OR 2.3; 95% CI 1.8-3.0; p < 0.001) at 3 months after stroke. The rate of 3-month disability was lower in patients who had received EDS (52 vs. 40.7%; p = 0.003), albeit an association in the logistic regression was not found (OR 0.78; 95% CI 0.51-1.2; p = 0.2). Conclusions: Dysphagia exposes stroke patients to a higher risk of pneumonia, disability, and death, whereas an EDS seems to be associated with reduced risk of stroke-related pneumonia and disability.

Introduction: Revascularization is a robust therapy for acute ischemic stroke, but animal studies suggest that reperfusion edema may attenuate its beneficial effects. In stroke patients, early reperfusion consistently reduces infarct volume and improves long-term functional outcome, but there is little clinical data available regarding reperfusion edema. We sought to elucidate the relationship between reperfusion and brain edema in a patient cohort of moderate to severe stroke. Methods: Seventy-one patients enrolled in the Echoplanar Imaging Thrombolysis Evaluation Trial (EPITHET) with serial brain magnetic resonance imaging and perfusion-weighted imaging (PWI) were analyzed. Reperfusion percentage was calculated based on the difference in PWI lesion volume at baseline and follow-up (day 3-5). Midline shift (MLS) was measured on the day 3-5 fluid attenuated inversion recovery (FLAIR) sequence. Swelling volume and infarct growth volume were assessed using region-of-interest analysis on the baseline and follow-up DWI scans based on our prior methods. Results: Greater percentage of reperfusion was associated with less MLS (Spearman ρ = -0.46; P <0.0001) and reduced swelling volume (Spearman ρ = -0.56; P <0.0001). In multivariate analysis, reperfusion was an independent predictor of less MLS ( P <0.006) and decreased swelling volume ( P <0.0054), after adjusting for age, baseline NIHSS, admission blood glucose, baseline DWI volume, and IV tPA treatment. Conclusions: Reperfusion is associated with reduced brain edema as measured by MLS and swelling volume. While our data do not exclude the possibility of reperfusion edema in certain circumstances, in stroke patients, reperfusion following acute stroke is predominantly linked to less brain swelling.

Introduction: The effects of blood pressure (BP) reduction on clinical outcomes among acute stroke patient remain uncertain. Hypothesis: We tested the effects of immediate BP reduction on death and major disability at 14 days or hospital discharge and 3-month follow-up in acute ischemic stroke patients with and without a previous history of hypertension or use of antihypertensive medications. Methods: The China Antihypertensive Trial in Acute Ischemic Stroke (CATIS) randomly assigned patients with ischemic stroke within 48 hours of onset and elevated systolic BP (SBP) to receive antihypertensive treatment (N=2,038) or to discontinue all antihypertensive medications (N=2,033) during hospitalization. Randomization was stratified by participating hospitals and use of antihypertensive medications. Study outcomes were assessed at 14 days or hospital discharge and 3-month post-treatment follow-up. The primary outcome was death and major disability (modified Rankin Scale score≥3), and secondary outcomes included recurrent stroke and vascular events. Results: Mean SBP was reduced 12.7% in the treatment group and 7.2% in the control group within 24 hours after randomization (P<0.001). Mean SBP was 137.3 mmHg in the treatment group and 146.5 in the control group at day 7 after randomization (P<0.001). At 14 days or hospital discharge, the primary and secondary outcomes were not significantly different between the treatment and control groups by subgroups. At the 3-month follow-up, recurrent stroke was significantly reduced in the antihypertensive treatment group among patients with a history of hypertension (odds ratio 0.43, 95% CI 0.24-0.75, P=0.003) and among patients with a history of use of antihypertensive medications (odds ratio 0.41, 95% CI 0.20-0.84, P=0.01). All-cause mortality (odds ratio 2.84, 95% CI 1.11-7.27, P=0.03) was increased among patients without a history of hypertension. Conclusion: Immediate BP reduction lowers recurrent stroke among acute ischemic stroke patients with a previous history of hypertension or use of antihypertensive medications at 3 months. On the other hand, BP reduction increases all-cause mortality among patients without a history of hypertension.

<p><strong>Introduction</strong>: The prevalence of stroke in Indonesia increased from 8.3 per 1000 population in 2007 to 12.1 per 1000 population in 2013, based on Riset Kesehatan Dasar (RISKESDAS) 2013. Diabetes mellitus (DM) is an independent risk factor and can be modified. Hyperglycemia that occurs in the acute phase of stroke is associated with an increase in mortality and poor clinical outcome after stroke. Moreover, stroke patients are at risk of developing hypoalbuminemia due to poor intake and the presence of a chronic inflammatory process.<br /><strong>Methods:</strong> A 66-year-old female patient with third recurrent ischemic stroke, history of uncontrolled DM, conciousness based on GCS is E3M5Vaphasia, Nasogastric tube (NGT) was inserted and there was a right facial nerve paralysis and bilateral hemiparesis . Nutritional status of patient is obese-1. During follow up period, the patient's blood glucose level ranged from 194 g/dl-345 g/dl. Nutrition therapy is given with a target of 1350 kcal (32 kcal/kg). Its composition consists of 15% protein, 25% fat and 60% carbohydrate (preferred complex carbohydrates), in the form of DM-specific formula containing inulin and monounsaturated fatty acid (MUFA). This nutritional therapy was administrated six times per day via enteral pathway, followed by the administration of micronutrients of vitamins C, B and folic acid.<br /><strong>Result:</strong> During follow up period, the patient tolerated well with the diet. After the 14 days hospitalization, there was improvement of blood glucose level (&lt;200 g/dL). Albumin level increases from 2.5 g/dL to 2.9 g/dl by the nutritional therapy containing protein more than 1.2 g/kg/day.<br /><strong>Conclusion:</strong> Administering a diet with the recommended composition and formula helps control hyperglycemia and improve hypoalbuminemia in patients that can improve the patient's clinical condition.</p>
