Risk of Early Bleeding with Dual Antiplatelet Therapy in Acute Stroke and Transient Ischemic Attack Regardless of NIHSS Admission.

Background: Dual antiplatelet therapy (DAT) is a therapeutic option for patients with minor ischemic stroke (IS) or transient ischemic attack (TIA). No study has evaluated the incidence of early bleeding in patients with moderate to major ischemic stroke. The current study aimed to analyze both the frequency of early bleeding and hospital morbidity related to DAT for either acute IS or TIA regardless of admission National Institute of Health Stroke Scale (NIHSS) score.

Neurological complications of heart failure.

Heart failure (HF) is a major global cause of death with increasing absolute worldwide numbers of HF patients. HF results from the interaction between cardiovascular aging with specific risk factors, comorbidities, and disease modifiers. The failing heart and neuronal injury have a bidirectional interaction requiring specific management strategies.

Evaluation of cerebral autoregulation performance in patients with arterial hypertension on drug treatment.

Cerebral autoregulation (AR) keeps cerebral blood flow constant despite fluctuations in systemic arterial pressure. The final common AR pathway is made up of vasomotor adjustments of cerebrovascular resistance mediated by arterioles. Structural and functional changes in the arteriolar wall arise with age and systemic arterial hypertension.

Improving economic evaluations in stroke: A report from the ESO Health Economics Working Group.

Introduction: Approaches to economic evaluations of stroke therapies are varied and inconsistently described. An objective of the European Stroke Organisation (ESO) Health Economics Working Group is to standardise and improve the economic evaluations of interventions for stroke.

Methods: The ESO Health Economics Working Group and additional experts were contacted to develop a protocol and a guidance document for data collection for economic evaluations of stroke therapies.

Latin American Consensus Statement for the Use of Contrast-Enhanced Transcranial Ultrasound as a Diagnostic Test for Detection of Right-to-Left Shunt.

Background: The role of patent foramen ovale is a field of debate and current publications have increasing controversies about the patients' management in young undetermined stroke. Work up with echocardiography and transcranial Doppler (TCD) can aid the decision with better anatomical and functional characterization of right-to-left shunt (RLS). Medical and interventional strategy may benefit from this information.

Stroke Care and Application of Thrombolysis in Ibero-America: Report From the SITS-SIECV Ibero-American Stroke Register.

Background And Purpose: Standardized registries may provide valuable data to further improve stroke care. Our aim was to obtain updated information about characteristics of stroke patients and management of stroke across the Ibero-American countries, using a common in-hospital registry (Safe Implementation of Treatments in Stroke–Sociedad Iberoamericana de Enfermedades Cerebrovasculares) as a basis for further quality improvement.

Methods: Data for this study were entered into the Safe Implementation of Treatments in Stroke registry from September 2009 to December 2013 by 58 centers in 14 countries.

Impact of Low Ankle-Brachial Index on the Risk of Recurrent Vascular Events.

Background and Purpose- Low ankle-brachial index (ABI) identifies a stroke subgroup with high risk of recurrent stroke, cardiovascular events, and death. However, limited data exist on the relationship between low ABI and stroke in low and middle-income countries. Therefore, we evaluated the prevalence of ABI ≤0.

Impact of hypertension severity on arterial stiffness, cerebral vasoreactivity, and cognitive performance.

Unlabelled: Aging, hypertension (HTN), and other cardiovascular risk factors contribute to structural and functional changes of the arterial wall.

Objective: To evaluate whether arterial stiffness (AS) is related to cerebral blood flow changes and its association with cognitive function in patients with hypertension.

Methods: 211 patients (69 normotensive and 142 hypertensive) were included.

Charles Miller Fisher: the 65th anniversary of the publication of his groundbreaking study "Transient Monocular Blindness Associated with Hemiplegia".

Charles Miller Fisher is considered the father of modern vascular neurology and one of the giants of neurology in the 20th century. This historical review emphasizes Prof. Fisher's magnificent contribution to vascular neurology and celebrates the 65th anniversary of the publication of his groundbreaking study, "Transient Monocular Blindness Associated with Hemiplegia.

Higher arterial stiffness is associated with lower cognitive performance in patients with hypertension.

Cognitive impairment and elevated arterial stiffness have been described in patients with arterial hypertension, but their association has not been well studied. We evaluated the correlation of arterial stiffness and different cognitive domains in patients with hypertension compared with those with normotension. We evaluated 211 patients (69 with normotension and 142 with hypertension).

Stroke Prevention in Atrial Fibrillation: Focus on Latin America.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, with an estimated prevalence of 1-2% in North America and Europe. The increased prevalence of AF in Latin America is associated with an ageing general population, along with poor control of key risk factors, including hypertension. As a result, stroke prevalence and associated mortality have increased dramatically in the region.

Brazilian guidelines for endovascular treatment of patients with acute ischemic stroke.

These guidelines are the result of a joint effort from writing groups of the Brazilian Stroke Society, the Scientific Department of Cerebrovascular Diseases of the Brazilian Academy of Neurology, the Brazilian Stroke Network and the Brazilian Society of Diagnostic and Therapeutic Neuroradiology. Members from these groups participated in web-based discussion forums with predefined themes, followed by videoconference meetings in which controversies and position statements were discussed, leading to a consensus. This guidelines focuses on the implications of the recent clinical trials on endovascular therapy for acute ischemic stroke due to proximal arterial occlusions, and the final text aims to guide health care providers, health care managers and public health authorities in managing patients with this condition in Brazil.

Hypertension Severity Is Associated With Impaired Cognitive Performance.

Background: Most evidence of target-organ damage in hypertension (HTN) is related to the kidneys and heart. Cerebrovascular and cognitive impairment are less well studied. Therefore, this study analyzed changes in cognitive function in patients with different stages of hypertension compared to nonhypertensive controls.

Evaluation of body temperature in individuals with stroke.

Background: A stroke can cause alterations in thermal sensitivity.

Objective: to verify the conditions of body temperature in hemiplegic patients after stroke as compared to healthy individuals, as well as establish relations between thermal sensitivity and gender, age, Body Mass Index (BMI), plegic side, time after stroke, reports of thermal alterations and the motricity of patients with stroke sequelae.

Methods: This cross-sectional study included 100 patients (55.

Overcoming global challenges in stroke prophylaxis in atrial fibrillation: The role of non-vitamin K antagonist oral anticoagulants.

Atrial fibrillation is the world's most common sustained cardiac arrhythmia and is associated with a significantly increased risk of stroke. The global burden of atrial fibrillation is rising, commensurate with the ageing population. Well-controlled vitamin K antagonist-based anticoagulation has been shown to reduce the risk of stroke secondary to atrial fibrillation by two-thirds.

Posterior Circulation Evaluation in Patients with Sickle Cell Anemia.

Background: The role of transcranial Doppler (TCD) ultrasonography in identifying children with sickle cell anemia (SCA) at risk for stroke is well known; however, the major studies that evaluated TCD velocities in children with SCA did not report posterior circulation evaluation data. The objective of our study was to describe the pattern of blood flow velocities in the posterior circulation of patients with SCA and to examine their relationship with findings on magnetic resonance imaging (MRI)/magnetic resonance angiography (MRA).

Methods: All adult patients with SCA followed in the outpatient clinic of our hospital were evaluated with TCD and MRI/MRA.
