Diffusion-weighted imaging reveals distinct patterns of cytotoxic edema in patients with subdural hematomas.

J Neurotrauma 2021 Jun 9. Epub 2021 Jun 9.

University of Cincinnati, 2514, Neurology and Rehabilitation Medicine, Cincinnati, Ohio, United States;

Subdural hematomas (SDHs) are increasingly common and can cause ischemic brain injury. Prior work has suggested that this is driven largely by vascular compression from herniation, although this work was done prior to the era of magnetic resonance imaging (MRI). We thus sought to study SDH-related ischemic brain injury by looking at patterns of cytotoxic edema on diffusion-weighted MRI. Read More

Anticoagulation Protocol for Secondary Prevention of Acute Ischemic Stroke Associated with Nonvalvular Atrial Fibrillation.

J Stroke Cerebrovasc Dis 2021 Jun 6;30(8):105893. Epub 2021 Jun 6.

Department of Stroke Medicine and Neurosurgery, Nayoro General Hospital, Nayoro City, Japan.

Objectives: There is no clear evidence regarding when to initiate oral anticoagulants (OACs) for secondary prevention of recurrent stroke in patients with atrial fibrillation (AF). Therefore, this study aimed to evaluate the safety and efficacy of a novel OAC initiation protocol for secondary prevention of acute ischemic stroke associated with AF.

Materials And Methods: In this multicenter prospective study 597 consecutive Japanese patients with acute ischemic stroke associated with nonvalvular AF received post-stroke OACs according to a protocol based on severity (clinical (NIHSS) and radiological (ASPECTS + W)), rt-PA use, reperfusion, and hemorrhagic transformation (HT).

Percutaneous Left Atrial Appendage Occlusion: An Emerging Option in Patients with Atrial Fibrillation at High Risk of Bleeding.

Medicina (Kaunas) 2021 May 3;57(5). Epub 2021 May 3.

Department of Translational Medical Sciences, University of Campania Luigi Vanvitelli, 80131 Naples, Italy.

Atrial fibrillation (AF) is a common cardiac arrhythmia with an estimated prevalence of 1% in the general population. It is associated with an increased risk of ischemic stroke, silent cerebral ischemia, and cognitive impairment. Due to the blood flow stasis and morphology, thrombus formation occurs mainly in the left atrial appendage (LAA), particularly in the setting of nonvalvular AF (NVAF). Read More

[Concepts and preconceptions on the use of direct oral anticoagulants in Italy: a Delphi consensus panel of the Atherosclerosis Thrombosis, Vascular Biology Study Group (ATBV)].

G Ital Cardiol (Rome) 2021 Jun;22(6):457-465

Ospedale "Maggiore della Carità", Università del Piemonte Orientale, Novara.

In the last decade, direct oral anticoagulants (DOACs) have entered the clinical practice of different specialists for the prevention of cardioembolic stroke in patients with non-valvular atrial fibrillation (NVAF) and the prevention and treatment of venous thromboembolism (VTE). Owing to the persistent uncertainties about the use of DOACs in daily clinical scenarios not fully explored in the clinical trials, we conducted a national Delphi consensus regarding issues deemed interesting by the Italian Atherosclerosis, Thrombosis and Vascular Biology (ATBV) Study Group in relation to: (i) elderly and/or frail patients; (ii) chronic kidney disease; (iii) drug-drug interactions; (iv) lower doses and safety; (v) criteria for choosing individual drugs and compliance; (vi) VTE in the cancer patient. Eighty-four Italian clinicians (cardiologists, internists, geriatricians, neurologists and hematologists) expressed their level of agreement on each statement using a 5-point Likert scale (1: very much in disagreement, 2: disagreement, 3: partial agreement, 4: agreement, 5: very much in agreement).

Combined Omic Analyzes of Cerebral Thrombi: A New Molecular Approach to Identify Cardioembolic Stroke Origin.

Stroke 2021 May 21:STROKEAHA120032129. Epub 2021 May 21.

Laboratory Transporter in Imaging and Radiotherapy in Oncology (TIRO), Direction de la Recherche Fondamentale (DRF), Institut des sciences du vivant Fréderic Joliot, Commissariat à l'Energie Atomique et aux énergies alternatives (CEA), Université Côte d'Azur (UCA), Nice, France (L.S., J.-M.G., F.G., S.L., T.P.).

Background And Purpose: The diagnosis of cardioembolic stroke can be challenging for patient management in secondary stroke prevention, particularly in the case of covert paroxysmal atrial fibrillation. The molecular composition of a cerebral thrombus is related to its origin. Therefore, proteomic and metabolomic analyses of the retrieved thrombotic material should allow the identification of biomarkers or signatures to improve the etiological diagnosis of stroke.

Stroke in Young Military Men With Heterozygous for MTHFR Gene Mutation or Factor V Leiden Gene Mutation Associated With Patent Foramen Ovale: Report of Two Cases and Therapeutic Strategy.

Mil Med 2021 May 16. Epub 2021 May 16.

Division of Neurology, Hospital Naval Marcílio Dias, Rio de Janeiro, Rio de Janeiro 20725-090, Brazil.

We report two cases of Brazilian patients (a 22-year-old male and a 48-year-old male) with ischemic stroke, whose arterial vascular study and echocardiographic investigation did not reveal any steno-occlusive arterial disease or typical cardioembolic finding, such as atrial fibrillation or myocardial dysfunction. A transcranial Doppler ultrasound and a transesophageal echocardiogram showed a patent foramen ovale (PFO), and the laboratory screening for coagulation abnormalities showed heterozygosity for MTHFR C677T and A1298C in one of the patients and heterozygosity for factor V Leiden gene mutations in the other patient. The significance of the association of PFO with Methylenetetrahydrofolate (MTHFR) C677T and A1298C variants or factor V Leiden mutation is discussed as a possible cause of ischemic stroke through paradoxical embolism from a venous source.

BNP combined with echocardiographic parameters to predict the risk of cardioembolic stroke.

J Clin Neurosci 2021 Jun 16;88:213-218. Epub 2021 Apr 16.

Department of Neurology, The Affiliated Hospital of Qingdao University, Qingdao 266000, China. Electronic address:
