Non-Vitamin K Oral Anticoagulants (NOACs) and Their Reversal
AbstractPurpose of ReviewAn 80-year-old man presents with an acute right hemiparesis and National Institutes of Health Stroke Scale (NIHSS) of 25, 14  h after taking dabigatran. Activated partial thromboplastin time (aPTT) is 42.8 s. Arteriogram demonstrates left internal carotid artery thrombosis. What is the appropriate management of this patient with acute ischemic stroke while on a NOAC?Recent FindingsIdarucizumab is a reversal agent approved for dabigatran, and two more reversal agents, andexanet alfa and aripazine, are currently in development for NOACs.SummaryIn this article, we review currently available NOACs, t...

Effects of task-specific rehabilitation training on tau modification in rat with photothrombotic cortical ischemic damage
Publication date: September 2017 Source:Neurochemistry International, Volume 108 Author(s): Kyung-Lim Joa, Sohee Moon, Ji-Hye Kim, Dong Wun Shin, Kyoung-Hee Lee, Seon Jung, Myeong-Ok Kim, Chang-Hwan Kim, Han-Young Jung, Ju-Hee Kang Although stroke elicits progressive cognitive decline and is a leading cause of dementia, molecular interplay between stroke and Alzheimer's disease (AD) pathology has not been fully elucidated. Furthermore, studies on the effects of post-stroke rehabilitation on AD pathology are limited. We evaluated the acute effect of stroke on tau modification, and the molecular effects of task-specific tra...

Evaluation of functional outcome measured by modified Rankin scale in rtPA treated patients with acute ischemic stroke.
Authors: Georgievski-Brkic B, Savic M, Nikolic D, Nikcevic L, Vukicevic M, Kozic D Abstract Aim of our study was to assess functional outcome measured by modified Rankin scale (mRS) in patients that were treated with thrombolytic therapy-recombinant tissue plasminogen activator (rtPA) after acute ischemic stroke. The study included 100 participants that were treated after acute ischemic stroke. Analyzed parameters included: gender; age groups: age 54 and below (Groupup to-54), 55-64 (Group55-64), 65-74 (Group65-74), and 75 and above (Group75-up); cerebral blood flow (CBF) and cerebral blood volume (CBV). Considerin...

Evaluation of the role of susceptibility-weighted imaging in thrombolytic therapy for acute ischemic stroke
Publication date: Available online 20 February 2017 Source:Journal of Clinical Neuroscience Author(s): Guangjian Zhao, Ling Sun, Ziran Wang, Liquan Wang, Zhongrong Cheng, Hongyan Lei, Daiqun Yang, Yansen Cui, Shirui Zhang We inspected low-intensity venous signals and microbleeds in patients with acute ischemic stroke (AIS) using susceptibility-weighted imaging (SWI) before and after administration of within-thrombolytic-time-window thrombolytic therapies, and observed their prognosis and safety, in order to guide individualized thrombolytic therapies. Patients with AIS were divided into groups A or B according to the pres...

Pharmacologic cardioversion with intravenous amiodarone is likely safe in neurocritically Ill patients
Publication date: Available online 13 February 2017 Source:Journal of Clinical Neuroscience Author(s): Michael Su, David Seki, Asma M. Moheet Neurological injury is often associated with cardiac abnormalities, including electrophysiological issues. Cardioversion of acute atrial fibrillation (<48h’ duration) without anticoagulation carries about a 0.7% risk of thromboembolism. There is limited data on managing acute atrial fibrillation specifically in the neuroscience intensive care unit (NSICU) setting. We sought to determine the safety of using intravenous (IV) amiodarone for restoring sinus rhythm in patients w...

The establishment of a telestroke service using multimodal CT imaging decision assistance: “Turning on the fog lights”
Publication date: March 2017 Source:Journal of Clinical Neuroscience, Volume 37 Author(s): Jelle Demeestere, Claire Sewell, Jennifer Rudd, Timothy Ang, Louise Jordan, James Wills, Carlos Garcia-Esperon, Ferdinand Miteff, Venkatesh Krishnamurthy, Neil Spratt, Longting Lin, Andrew Bivard, Mark Parsons, Christopher Levi Telestroke services have been shown to increase stroke therapy access in rural areas. The implementation of advanced CT imaging for patient assessment may improve patient selection and detection of stroke mimics in conjunction with telestroke. We implemented a telestroke service supported by multimodal CT ima...

Stroke biomarkers in clinical practice: A critical appraisal
Publication date: Available online 11 January 2017 Source:Neurochemistry International Author(s): Geelyn J.L. Ng, Amy M.L. Quek, Christine Cheung, Thiruma V. Arumugam, Raymond C.S. Seet Biomarkers provide critical mechanistic insights to key biologic processes that occur during cerebral ischemia which, when carefully applied, can improve clinical decision-making in acute stroke management. The translation of a blood-based biomarker in ischemic stroke to clinical practice is challenging, in part, due to the complexity of ischemic stroke pathogenesis and the presence of a blood-brain barrier that restricts the release of br...

Acute bithalamic infarct manifesting as sleep-like coma: A diagnostic challenge
Publication date: December 2016 Source:Journal of Clinical Neuroscience, Volume 34 Author(s): Asaf Honig, Ruth Eliahou, Roni Eichel, Ari Aharon Shemesh, Tamir Ben-Hur, Eitan Auriel Bilateral thalamic infarction (BTI) typically presents as a sleep-like coma (SLC) without localizing signs, posing a diagnostic challenge that may lead the treating physician to search for toxic or metabolic causes and delay treatment. We review our experience with BTI of different etiologies, and emphasize the critical role of timely imaging, diagnosis, and management in a series of 12 patients with a presentation of SLC and acute BTI who were...

Oxidative stress and glutamate excitotoxicity contribute to apoptosis in cerebral venous sinus thrombosis
Publication date: November 2016 Source:Neurochemistry International, Volume 100 Author(s): Hari Shanker Tiwari, Usha Kant Misra, Jayantee Kalita, Akanksha Mishra, Shubha Shukla Cerebral venous sinus thrombosis (CVST) is an important cause of stroke in young especially in the developing countries. There is paucity of studies on the mechanism of cell damage in CVST. Aim of this study is to explore the role of glutamate excitotoxicity, oxidative stress; and apoptosis in an experimental model of CVST. Cerebral venous sinus thrombosis was induced by putting a strip of filter paper soaked in 40% ferric chloride on superior sagi...

Expanding the concept of neuroprotection for acute ischemic stroke: the pivotal roles of reperfusion and the collateral circulation
Publication date: Available online 13 September 2016 Source:Progress in Neurobiology Author(s): Myron D. Ginsberg This review surveys the efforts taken to achieve clinically efficacious protection of the ischemic brain and underscores the necessity of expanding our purview to include the essential role of cerebral perfusion and the collateral circulation. We consider the development of quantitative strategies to measure cerebral perfusion at the regional and local levels and the application of these methods to elucidate flow-related thresholds of ischemic viability and to characterize the ischemic penumbra. We stress that...

Publication date: Available online 16 July 2016 Source:Journal of Clinical Neuroscience Author(s): Omar Choudhri, Matthew Schoen, Aditya Mantha, Abdullah Feroze, Rohaid Ali, Michael T. Lawton, Huy M. Do The full utility of diagnostic cerebral angiography, an invasive cerebrovascular imaging technique, is currently debated. Our goal was to determine trends in diagnostic cerebral angiography utilization and associated complications from 1999 through 2009. The National Inpatient Sample (NIS) was used to identify patients who received primary cerebral angiography from 1999–2009 in the United States. We observed tren...

Neurological complications of acute multifocal placoid pigment epitheliopathy
The objective of this patient series is to describe the neurological complications of AMPPE. We retrospectively identified patients with neurological complications of AMPPE seen at Auckland Hospital between 2008 and 2013 and summarised cases in the literature between 1976 and 2013. We identified five patients with neurological complications of AMPPE at Auckland Hospital and 47 reported patients. These patients demonstrated a spectrum of neurological involvement including isolated headache, stroke or transient ischaemic attack, seizures, venous sinus thrombosis, optic neuritis, sensorineural hearing loss and peripheral vest...
