Use of rivaroxaban in patients with stroke.

Rivaroxaban, an inhibitor of Factor Xa, is a direct oral anti-coagulant that has been found to be non-inferior to warfarin in preventing cerebral ischemia in patients with non-valvular atrial fibrillation and in the subgroup of patients with a history of the previous stroke or transient ischemic attack. Vascular neurologists in daily clinical practice may encounter patients taking rivaroxaban or patients who may benefit from its use. In this paper, we review the current clinical indications, contraindications, and clinical management guidelines for rivaroxaban while providing a special focus on neurological aspects and expert opinions on rivaroxaban therapy management in various situations that a neurologist may encounter when treating patients with an ischemic stroke (including those requiring intravenous or intra-arterial reperfusion therapy) and patients with an intracerebral hemorrhage.

Recommendations for the use of new oral anticoagulants (NOACs) after TIA or stroke caused by atrial fibrillation (AF), after a consensus conference among Italian neurologists (the Venice group).

Vascular neurologists of Veneto and Friuli Venezia Giulia, north-east regions of Italy, have sought an agreement on the two following questions: (A) what prophylactic treatment should we recommend to patients with a stroke ascribed to atrial fibrillation (AF), who were not previously on antithrombotic treatment, to prevent further strokes? (B) What should we do in the event of an ischemic or hemorrhagic stroke associated with AF in patients who were already on antithrombotic treatment? There was a unanimous consensus for preferring the new oral anticoagulants (NOACs) in patients not taking any antithrombotics and in cases treated with antithrombotic drugs (coumadin and/or antiplatelets), due to a lower incidence of intracranial bleeding complications and a noninferiority for recurrent stroke or TIA. Even after intracranial bleeding complications, when it is useful or necessary to continue anticoagulant treatment, the group of experts preferred the NOACs, suggesting, however, to be very cautious in cases with widespread leukoaraiosis or microbleeds, practice frequent monitoring of creatinine clearance (CrCl) and avoid using NOACs when CrCl is <30 mL/min.

The social and economic burden of stroke survivors in Italy: a prospective, incidence-based, multi-centre cost of illness study.

Background: The aim of this study was to estimate the one-year societal costs due to a stroke event in Italy and to investigate variables associated with costs in different phases following hospital admission.

Methods: The patients were enrolled in 44 hospitals across the country and data on socio-demographic, clinical variables and resource consumption were prospectively surveyed for 411 stroke survivors at admission, discharge and 3, 6 and 12 months post the event. We adopted a micro-costing procedure to identify cost generating components and the attribution of appropriate unit costs for three cost categories: direct healthcare, direct non-healthcare (including informal care costs) and productivity losses.

Variability of the clinical phenotype in an Italian family with dementia associated with an intronic deletion in the GRN gene.

Mutations in the progranulin gene (GRN) were recently identified as an important cause of familial frontotemporal dementia (FTD). More than 60 pathogenic mutations have been reported up to now and prominent phenotypic variability within and among affected kindreds has been described. We have studied an Italian family with clinical evidence of dementia, and here we report detailed clinical records, imaging, sequential neurological examinations, cognitive assessments, and genetic analysis of three affected members of the same generation.

Acute stroke admission and diagnostic procedures according to the hour and day of onset: the SIRIO collaborative data.

Background: Variations in stroke onset are related to stroke type and severity. We evaluated the impact of hourly and daily stroke onset variations on the pattern of patient hospital referral and on the time interval from stroke onset to hospital admission and brain neuroimaging investigations.

Methods: This multicenter observational study recorded all incident acute strokes within a 4-month period.

Depression after first-ever ischemic stroke: the prognostic role of neuroanatomic subtypes in clinical practice.

Background: The relationship between poststroke depression (PSD) and Oxford Community Stroke Project (OCSP) subtypes is uncertain.

Methods: 713 first-ever ischemic stroke patients recruited in a multicenter investigation to evaluate prevalence, onset time and severity of PSD. Stroke subtypes were considered as independent predictors of PSD occurrence by logistic regression.

The neurologist in the emergency department. An Italian nationwide epidemiological survey.

A nationwide survey has been undertaken to evaluate the resources and the activities of Italian hospital neurology units (NU) in the emergency setting. NU are widely disseminated throughout the entire country and 220 (84%) are located in hospitals with an emergency room (ER). Complete data about hospital setting, structural and functional characteristics of each NU and clinical activities were obtained from 159 (72.

Intravenous thrombolysis with rt-PA in acute ischemic stroke patients aged older than 80 years in Italy.

Background: Intravenous (i.v.) thrombolysis with rt-PA within 3 h from symptom onset is the only approved treatment of pharmacological revascularization in acute ischemic stroke.

The Italian multicenter observational study on post-stroke depression (DESTRO).

Despite growing information, questions still surround various aspects of post-stroke depression (PSD). The Italian multicenter observational study Destro was designed to help clarify in a large sample the frequency and clinical impact of PSD. A total of 53 centers consecutively admitted 1064 patients with ischemic or hemorrhagic stroke, assessing them periodically in the first 9 months after the event.

Plasma cytokine levels in migraineurs and controls.

Background: The vasoactive peptide, calcitonin gene-related peptide (CGRP), is released from primary afferent neurons in the trigemino-vascular circulation during migraine headache. CGRP at physiological concentrations and possibly via stimulation of its selective receptors on T-cells, triggers the secretion of cytokines. Cytokines play an important role in several physiological and pathological settings such as immunology, inflammation, and pain.

Measuring accuracy of discharge diagnoses for a region-wide surveillance of hospitalized strokes.

Background And Purpose: Measuring the impact of stroke through population-based stroke registers is complex and costly. The aim of the present study is to assess the validity of hospital discharge diagnoses (all ages) and to estimate the total number of hospitalized stroke events in the Veneto region (Northeastern Italy, 4,500,000 inhabitants).

Methods: All discharges covering a 1-year period (1999) from Veneto hospitals with International Classification of Diseases, 9th Revision codes 342, 430 to 434, and 436 to 438 were identified.

Endogenous task shift processes in relapsing-remitting multiple sclerosis.

This paper reports a study that was aimed to evaluate executive functions in relapsing-remitting multiple sclerosis patients. The groups tested comprised 22 relapsing-remitting multiple sclerosis patients, and 22 non-brain damaged controls. When one is engaged in two speeded tasks, not simultaneously but with some form of alternation, it is slower to respond to an item of task A if it was preceded by an item of task B, than when it was preceded by an item of task A.
