OBJECTIVE: To identify the most accurate quantitative electroencephalographic (qEEG) predictor(s) of unfavorable post-ischemic stroke outcome, and its discriminative capacity compared to already known demographic, clinical and imaging prognostic markers. METHODS: Prospective cohort of 151 consecutive anterior circulation ischemic stroke patients followed for 12 months. EEG was recorded within 72 h and at discharge or 7 days post-stroke. QEEG (global band power, symmetry, affected/unaffected hemisphere and time changes) indices were calculated from mean Fast Fourier Transform and analyzed as predictors of unfavorable outcome (mRS ≥ 3), at discharge and 12 months poststroke, before and after adjustment for age, admission NIHSS and ASPECTS...

BACKGROUND: Whether echocardiography platform and analysis software impact left ventricular (LV) volumes, ejection fraction (EF), and stroke volume (SV) by transthoracic tridimensional echocardiography (3DE) has not yet been assessed. Hence, our aim was to compare 3DE LV end-diastolic and end-systolic volumes (EDV and ESV), LVEF, and SV obtained with echocardiography platform from 2 different manufacturers. METHODS: 3DE was performed in 84 patients (65% of screened consecutive patients), with equipment from 2 different manufacturers, with subsequent off-line postprocessing to obtain parameters of LV function and size (Philips QLAB 3DQ and General Electric EchoPAC 4D autoLVQ)...

BACKGROUND: Orbital infarction syndrome (OIS) is a rare entity defined as ischemia of all intraorbital and intra-occular structures including the optic nerve, extraocular muscles and orbital fat. This entity is rare due to rich anastomotic orbital vascularization from both the internal carotid artery and external carotid artery. We report a case of a patient who suffered ENT to the ophthalmic artery and external carotid artery which resulted in orbital infarction syndrome and describe techniques to avoid such complications...

BACKGROUND: Injection of a clot into the internal carotid artery is an experimental model of ischemic stroke that is considered to closely mimic embolic stroke in humans. In this model, the common carotid artery typically remains temporarily occluded to permit time for stabilization of the clot in the middle cerebral artery. However, the associated lengthening of the anesthesia duration could affect arterial blood pressure and stroke outcome. NEW METHOD: We refined the model by examining how increasing isoflurane anesthesia duration from 30 to 60 min after clot embolization affects mortality, infarct volume, edema, blood-brain barrier permeability, and the 8-h post-ischemic time course of blood pressure, which has not been reported previously in this model...

Ischemic stroke is a devastating and debilitating medical condition with limited therapeutic options. However, accumulating evidence indicates a central role of inflammation in all aspects of stroke including its initiation, the progression of injury, and recovery or wound healing. A central target of inflammation is disruption of the blood brain barrier or neurovascular unit. Here we discuss recent developments in identifying potential molecular targets and immunomodulatory approaches to preserve or protect barrier function and limit infarct damage and functional impairment...

BACKGROUND AND PURPOSE: Cerebrovascular responses to head-of-bed positioning in patients with acute ischemic stroke are heterogeneous, questioning applicability of general recommendations on head positioning. Cerebral autoregulation is impaired to various extents after acute stroke, while it is unknown whether this affects cerebral perfusion during posture change. We aimed to elucidate whether the cerebrovascular response to head position manipulation depends on autoregulatory performance in ischemic stroke patients...

Dual antiplatelet therapy with aspirin and clopidogrel are recommended as adjuncts to fibrinolytic-treated patients with ST-elevation myocardial infarction (STEMI). However, the role of switching to ticagrelor within 24 h of fibrinolytics compared with clopidogrel continuation in this setting is uncertain. Hence, we conducted a comprehensive search of electronic databases for all randomized clinical trials (RCTs) that evaluated the safety and efficacy of ticagrelor versus clopidogrel after fibrinolytic therapy in patients with STEMI...

Acute ischaemic stroke represents the most common cause of new sudden neurological deficit, but other diseases mimicking stroke happen in about one-third of the cases. Magnetic resonance imaging (MRI) is the best technique to identify those 'stroke mimics'. In this article, we propose a diagnostic approach of those stroke mimics on MRI according to an algorithm based on diffusion-weighted imaging (DWI), which can be abnormal or normal, followed by the results of other common additional MRI sequences, such as T2 with gradient recalled echo weighted imaging (T2-GRE) and fluid-attenuated inversion recovery (FLAIR)...

Predictors of outcomes in patients with heart failure with preserved left-ventricular ejection fraction (HFpEF) remain unclear. The ratio of early diastolic transmitral flow velocity to early diastolic myocardial velocity (E/e') has been proposed, but the predictive accuracy remains unsatisfactory. We hypothesized that E/e' normalized by the stroke volume (SV), E/e'/SV, could be a good predictor of outcome in HFpEF patients by reflecting the terminal slope of the end-diastolic pressure-volume relation, i.e...

Risk of dementia is increased in patients with atrial fibrillation (AF). We aimed to study associations between relevant comorbidities and prevalent as well as incident dementia in AF patients. Study population included all adults (n = 12,283) ≥ 45 years diagnosed with AF at 75 primary care centers in Sweden 2001-2007. Logistic regression was used to calculate odds ratios (OR) with 95% confidence intervals (95% CI) for associations between comorbidities and prevalent dementia. In a subsample (n = 12,096), (excluding patients with dementia diagnosed before AF onset), Cox regression was used to estimate hazard ratios (HR) with 95% CIs for association between comorbidities, and incident dementia, after adjustment for age, socioeconomic factors and anticoagulant treatment...

This study aimed to examine the effectiveness of defibrinogen therapy on functional recovery and safety among 1332 consecutive ischemic stroke patients who had not received intravenous thrombolysis with recombinant tissue plasminogen activator. Stroke patients undergoing conservative and relatively individualized multiple-day dosing regimens of defibrinogen therapy between January 1, 2008 and May 30, 2016 were enrolled. Data were analyzed according to functional success (Barthel Index of 95 or 100, mRS of 0 or 1) and safety variables (intracranial hemorrhage, mortality and stroke recurrence)...

The prognostic relevance of strokes in different locations is debated. For example, insular strokes have been associated with increased mortality, but this association could reflect their greater severity. In two independent cohorts of patients with supratentorial ischemic stroke (n = 90 and 105), we studied the prognostic consequences of lesion size and location using voxel-based lesion-symptom mapping before and after volume control, which better accounts for total lesion volume. Strokes affecting the insula were larger than non-insular strokes (28 vs 2cc and 25 vs 3cc, p < 0...

BACKGROUND: Currently, acute ischemic stroke is still a leading cause of mortality and morbidity. Approximately 2 years ago, mechanical thrombectomy was proven beneficial as a revolutionary new therapy for stroke in the MR-CLEAN trial (A Multicenter Randomized Clinical Trial of Endovascular Treatment for Acute Ischemic Stroke in the Netherlands). However, the mechanisms by which the thrombectomy device, or stent-retriever, interacts with the thrombus are largely unknown. A better understanding could lead to improved efficacy of mechanical thrombectomy devices...

INTRODUCTION: Acute lymphoblastic leukaemia is the most common paediatric cancer. Survivors of childhood acute lymphoblastic leukaemia (SALL) are at risk of obesity and related cardiometabolic diseases including type 2 diabetes, hypertension, stroke and cardiovascular events. Therefore, it is important to address obesity in this population as this may help mitigate future cardiometabolic comorbidities. In this systematic review, we aim to assess current treatment strategies including lifestyle interventions, pharmacotherapy and bariatric surgery to manage overweight and obesity in SALL...

INTRODUCTION: Poststroke cognitive impairment is one of the most common complications in stroke survivors, and >65% of these patients suffer from cognitive impairment at 12 months following onset, which strongly affects the rehabilitation of their motor function and quality of life. Therefore, it is important to improve the cognitive ability of stroke survivors. As an important component of traditional Chinese Qigong exercises, characterised by the coordination of mind and body with a low exercise intensity, Baduanjin has the potential benefit of improving cognitive ability for patients who had a stroke with cognitive impairment...

Background -The Insulin Resistance Intervention after Stroke (IRIS) trial demonstrated that pioglitazone reduced risk for both cardiovascular events and diabetes in insulin resistant patients. However, concern remains that pioglitazone may increase risk for heart failure (HF) in susceptible individuals. Methods -In IRIS, patients with insulin resistance but without diabetes were randomized to pioglitazone or placebo (1:1) within 180 days of an ischemic stroke or TIA and followed for up to 5 years. To identify patients at higher HF risk with pioglitazone we performed a secondary analysis of IRIS participants without HF history at entry...
