Stroke profile and care during the COVID-19 pandemic: What changed and what did not? A prospective cohort from Joinville, Brazil
This study aims to investigate the impact of COVID-19 pandemic on stroke profile and care in Joinville, Brazil.MethodsA prospective population-based cohort enrolled the first-ever cerebrovascular events in Joinville, Brazil, and a comparative analyzes was conducted between the first 12 months following COVID-19 restrictions (starting March 2020) and the 12 months just before. Patients with transient ischemic attack (TIA) or stroke had their profiles, incidences, subtypes, severity, access to reperfusion therapy, in-hospital stay, complementary investigation, and mortality compared.ResultsThe profiles of TIA/stroke patients...

A rare cause of monogenic cerebral small vessel disease and stroke: Cathepsin A-related arteriopathy with strokes and leukoencephalopathy (CARASAL)
ConclusionsCARASAL should be considered in patients with early onset or severe cerebral small vessel disease, particularly where there are prominent symptoms or signs related to brainstem involvement, such as hearing dysfunction, tinnitus or dysphagia or where there is significant thalamic and brainstem involvement on imaging.

Modeling functional network topology following stroke through graph theory: functional reorganization and motor recovery prediction
Braz J Med Biol Res. 2022 Aug 15;55:e12036. doi: 10.1590/1414-431X2022e12036. eCollection 2022.ABSTRACTThe study of functional reorganization following stroke has been steadily growing supported by advances in neuroimaging techniques, such as functional magnetic resonance imaging (fMRI). Concomitantly, graph theory has been increasingly employed in neuroscience to model the brain's functional connectivity (FC) and to investigate it in a variety of contexts. The aims of this study were: 1) to investigate the reorganization of network topology in the ipsilesional (IL) and contralesional (CL) hemispheres of stroke patients wi...

The use of e-ASPECTS in acute stroke care: validation of method performance compared to the performance of specialists
Conclusion: e-ASPECTS is a validated and reliable tool for determining early signs of ischemia in NCCT.RESUMO Introdu ção: A avaliação rápida da tomografia de crânio sem contraste (TCSC) em pacientes com AVC de circulação anterior economiza tempo e permite um tratamento rápido e otimizado. O e-ASPECTS é um software que calcula automaticamente os valores do ASPECTS e permite uma avaliação da imagem mais precisa e ágil. Objetivo: Determinar a habilidade do e-ASPECTS em diferenciar imagens com e sem lesão. Métodos: Cento e dezesseis pacientes admitidos em uma unidade de AVC de um hospital terciário brasileiro ...

Modulating Applied Task Performance via Transcranial Electrical Stimulation
Conclusion tES may prove valuable for modulating applied task performance, though research in this area warrants careful consideration of several individual-, context-, and task-related factors that may predict the robustness and directionality of tES effects. Whereas most applied research with tES has administered tDCS, tACS and tRNS have also shown potential to modulate cortical activity and behavior. Even in highly applied and dynamic tasks, such as navigation and driving, tES appears to carry some performance benefits. This is compelling because as tES is slowly incorporated into highly complex real-world environments...

Anxiety in Patients With Acute Ischemic Stroke: Risk Factors and Effects on Functional Status
Conclusion: Depressive symptoms are the major correlates of PSA while more severe PSA is associated with poorer ADL and health-related QOL. Acute lesions involving CHWM may correlate with PSA in ischemic stroke patients with mild-to-moderate neurologic deficits, supporting a lesion-location hypothesis in PSA.IntroductionAnxiety is prevalent after stroke and occurs in about one-quarter of stroke survivors (1, 2). Poststroke anxiety (PSA) may have a negative impact on quality of life (QOL) of stroke survivors, affecting their rehabilitation (3). Furthermore, one prospective study found that severe anxiety symptoms were assoc...

Cerebellar infarct following orchidopexy under spinal anesthesia
Publication date: Available online 6 August 2018Source: Brazilian Journal of Anesthesiology (English Edition)Author(s): Sunny Goel, Gaurav Garg, Manoj Kumar, Ruchir AeronAbstractThe report describes a case of peri-operative stroke that presented as diplopia and gait difficulty on 2nd post-operative day after routine orchidopexy under spinal anesthesia in an otherwise healthy young boy. Magnetic resonance imaging of the brain revealed acute infarct in bilateral cerebellar hemispheres, left half of medulla and left thalamus. A diagnosis of acute stroke (infarct) was made and patient was started on oral aspirin 75 mg.day...
