Exploring Sex Differences in Outcomes of Dual Antiplatelet Therapy for Patients With Noncardioembolic Mild-to-Moderate Ischemic Stroke or High-Risk Transient Ischemic Attack: A Propensity-Matched Analysis of the READAPT Study Cohort.

Background: Sex may impact clinical outcomes in patients with stroke treated with dual antiplatelet therapy (DAPT). We aimed to investigate the sex differences in the short-term outcomes of DAPT within a real-world population of patients with noncardioembolic mild-to-moderate ischemic stroke or high-risk transient ischemic attack.

Methods: We performed a propensity score-matched analysis from a prospective multicentric cohort study (READAPT [Real-Life Study on Short-Term Dual Antiplatelet Treatment in Patients With Ischemic Stroke or Transient Ischemic Attack]) by including patients with noncardioembolic mild-to-moderate stroke (National Institutes of Health Stroke Scale score of 0-10) or high-risk transient ischemic attack (age, blood pressure, clinical features, duration of transient ischemic attack, presence of diabetes [ABCD] ≥4) who initiated DAPT within 48 hours of symptom onset.

Transient brain ischemic symptoms and the presence of ischemic lesions at neuroimaging: Results from the READAPT study.

Background: According to the literature, about one third of patients with brain ischemic symptoms lasting <24 h, which are classified as Transient ischemic attacks (TIAs) according to the traditional "time-based" definition, show the presence of acute ischemic lesions at neuroimaging. Recent evidence has shown that the presence of acute ischemic lesions at neuroimaging may impact on the outcome of patients with transient ischemic symptoms treated with dual antiplatelet treatment (DAPT). This uncertainty is even more compelling in recent years as short-term DAPT has become the standard treatment for any non-cardioembolic TIA or minor ischemic stroke.

Combining Intravenous Thrombolysis and Dual Antiplatelet Treatment in Patients With Minor Ischemic Stroke: A Propensity Matched Analysis of the READAPT Study Cohort.

Background: The optimal treatment for acute minor ischemic stroke is still undefined. and options include dual antiplatelet treatment (DAPT), intravenous thrombolysis (IVT), or their combination. We aimed to investigate benefits and risks of combining IVT and DAPT versus DAPT alone in patients with MIS.

Divergence Between Clinical Trial Evidence and Actual Practice in Use of Dual Antiplatelet Therapy After Transient Ischemic Attack and Minor Stroke.

Background: Randomized controlled trials (RCTs) proved that short-term (21-90 days) dual antiplatelet therapy (DAPT) reduces the risk of early ischemic recurrences after a noncardioembolic minor stroke or high-risk transient ischemic attack (TIA) without substantially increasing the hemorrhagic risk. We aimed at understanding whether and how real-world use of DAPT differs from RCTs.

Methods: READAPT (Real-Life Study on Short-Term Dual Antiplatelet Treatment in Patients With Ischemic Stroke or TIA) is a prospective cohort study including >18-year-old patients treated with DAPT after a noncardioembolic minor ischemic stroke or high-risk TIA from 51 Italian centers.

Medulla oblongata volume as a promising predictor of survival in amyotrophic lateral sclerosis.

Background: Unconventional magnetic resonance imaging studies of the brainstem have recently acquired a growing interest in amyotrophic lateral sclerosis (ALS) pathology since they provide a unique opportunity to evaluate motor tract degeneration and bulbar lower motor neuron involvement. The aim of this study was to investigate the role of brainstem structures as accurate biomarkers of disease severity and predictors of survival.

Materials And Methods: A total of 60 ALS patients and 30 healthy controls subjects (CS) were recruited in this study.

Morphological analysis of the brain subcortical gray structures in restless legs syndrome.

Background: Although several studies have shown the involvement of specific structures of the central nervous system, the dopaminergic system, and iron metabolism in restless legs syndrome (RLS), the exact location and extent of its anatomical substrate is not yet known. The scope of this new study was to investigate the brain subcortical gray structures, by means of structural magnetic resonance imaging (MRI) studies, in RLS patients in order to assess the presence of any volume or shape abnormalities involving these structures.

Methods: Thirty-three normal controls (24 females and nine males) and 45 RLS patients (34 females and 11 males) were retrospectively recruited and underwent a 1.

Fabry-Stroke Italian Registry (FSIR): a nationwide, prospective, observational study about incidence and characteristics of Fabry-related stroke in young-adults. Presentation of the study protocol.

Background: TIA and stroke, both ischemic and hemorrhagic, may complicate Fabry disease at young-adult age and be the first manifestation that comes to the clinician's attention. No definite indications have yet been elaborated to guide neurologists in Fabry disease diagnostics. In current practice, it is usually sought in case of cryptogenic strokes (while Fabry-related strokes can also occur by classical pathogenic mechanisms) or through screening programs in young cerebrovascular populations.

Guillain-Barré syndrome after AstraZeneca COVID-19-vaccination: A causal or casual association?

We report a case of Guillain-Barré syndrome (GBS) following the first dose of Oxford/AstraZeneca COVID-19 vaccine with papilledema as atypical onset. As the COVID-19 vaccination campaign progresses worldwide, GBSs vaccine-related have been increasingly reported. After reviewing the available literature, considering the annual incidence of GBS, in this historical moment, the public health systems cannot afford an unjustified distrust in vaccines, caused by misinterpretation of epidemiological data.

Magnetic resonance metrics to evaluate the effect of therapy in amyotrophic lateral sclerosis: the experience with edaravone.

Background: Edaravone was approved as a new treatment for amyotrophic lateral sclerosis (ALS), although there are different opinions on its effectiveness. Magnetic resonance (MRI) measures appear promising as diagnostic and prognostic indicators of disease. However, published studies on MRI using to monitor treatment efficacy in ALS are lacking.

Lymphocyte Count and Body Mass Index as Biomarkers of Early Treatment Response in a Multiple Sclerosis Dimethyl Fumarate-Treated Cohort.

In relapsing Multiple Sclerosis (RMS) patients treated with disease modifying drugs (DMDs), few data are available regarding the biomarkers of treatment response. We aimed to assess the predictive value of lymphocyte count (LC) and Body Mass Index (BMI) for treatment response in a real life setting of dimethyl fumarate (DMF) treated patients. We included in our observational analysis 338 patients who were prescribed DMF in an Italian MS Center.

Convexal subarachnoid hemorrhage and acute ischemic stroke: a border zone matter?

Background: Convexal subarachnoid hemorrhage (c-SAH) is an infrequent condition with variable causes. c-SAH concomitant to acute ischemic stroke (AIS) is even less frequent, and the relationship between the two conditions remains unclear.

Methods: Between January 2016 and January 2018, we treated four patients who were referred to our stroke unit with ischemic stroke and concomitant nontraumatic c-SAH.

Longitudinal Study on Low-Dose Aspirin versus Placebo Administration in Silent Brain Infarcts: The Silence Study.

Background: We investigated low-dose aspirin (ASA) efficacy and safety in subjects with silent brain infarcts (SBIs) in preventing new cerebrovascular (CVD) events as well as cognitive impairment.

Methods: We included subjects aged ≥45 years, with at least one SBI and no previous CVD. Subjects were followed up to 4 years assessing CVD and SBI incidence as primary endpoint and as secondary endpoints: (a) cardiovascular and adverse events and (b) cognitive impairment.

Cortical thinning and clinical heterogeneity in amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) has heterogeneous clinical features that could be translated into specific patterns of brain atrophy. In the current study we have evaluated the relationship between different clinical expressions of classical ALS and measurements of brain cortical thickness. Cortical thickness analysis was conducted from 3D-MRI using FreeSurfer software in 29 ALS patients and 20 healthy controls.

Parkinsonian syndromes.

The primary role of magnetic resonance imaging (MRI) in the evaluation of patients with parkinsonian syndromes is traditionally thought to be the differentiation between neurodegenerative and symptomatic parkinsonisms. Non conventional MRI techniques, however, could improve the clinical diagnosis by detecting ultrastructural damage even in brain regions not suspected to be involved. Moreover, functional MRI provides useful information upon the pathophysiology of Parkinson's disease.

Functional cortical changes of the sensorimotor network are associated with clinical recovery in multiple sclerosis.

Objective: To assess the early cortical changes following an acute motor relapse secondary to a pseudotumoral lesion in MS patients, the longitudinal cortical functional correlates of clinical recovery, and the evolution over time of cortical reorganization.

Methods: FMRI during the performance of a simple motor task were obtained from 12 MS patients (after a clinical attack involving the motor system secondary to a pseudotumoral lesion) and 15 matched controls. In six patients and five controls, a longitudinal fMRI study was also performed.

fMRI changes in relapsing-remitting multiple sclerosis patients complaining of fatigue after IFNbeta-1a injection.

If fatigue in multiple sclerosis (MS) is related to an abnormal activation of the sensorimotor brain network, the activity of such a network should vary with varying fatigue. We studied 22 patients treated with interferon beta 1a (IFNbeta-1a; Avonex, Biogen, Cambridge, MA) with no fatigue (10) and with reversible fatigue (12). fMRI examinations were performed: 1) the same day of IFNbeta-1a injection (no fatigue; entry), 2) the day after IFNbeta-1a injection (fatigue; time 1), and 3) 4 days after IFNbeta-1a injection (no fatigue; time 2).

An fMRI study of the motor system in patients with neuropsychiatric systemic lupus erythematosus.

Functional cortical changes have been demonstrated in patients with several neurological conditions, including stroke, tumors and MS. The correlation found between the extent of fMRI activations and the extent and severity of brain structural damage suggests an adaptive role of these functional changes. In this study, we assess, using fMRI, the brain pattern of movement-associated cortical activations in neuropsychiatric systemic lupus erythematosus (NPSLE) patients and investigate whether the extent of cortical reorganization is associated with the extent of brain pathology, measured on dual-echo and diffusion tensor (DT) MR images.

Glatiramer acetate in multiple sclerosis.

Glatiramer acetate (Copaxone) is a disease-modifying agent approved by several health authorities worldwide for the treatment of relapsing-remitting multiple sclerosis. Although its primary target is the inflammatory component of the disease, there are emerging pieces of evidence suggesting that glatiramer acetate might also have a neuroprotective effect. In this review, the results of glatiramer acetate clinical trials and other relevant studies as well as the place of glatiramer acetate among other approved disease-modifying treatments for relapsing-remitting multiple sclerosis are discussed critically.

A widespread pattern of cortical activations in patients at presentation with clinically isolated symptoms is associated with evolution to definite multiple sclerosis.

Background And Purpose: Movement-associated cortical changes have been detected at the earlier clinical stage multiple sclerosis. Our purpose was to assess whether different patterns of cortical recruitment are associated with the short-term evolution of definite multiple sclerosis (MS).

Methods: We followed for 1 year a group of patients with clinically isolated syndromes (CISs) suggestive of MS and compared the baseline movement-associated patterns of cortical activations between those patients with and those without evolution to definite MS.

Persistence of congenital mirror movements after hemiplegic stroke.

We describe a case of hereditary congenital mirror movements (MMs) in a 76-year-old man, who after an ischemic stroke, had persistence of MMs in the paretic hand during voluntary movements of the contralateral arm. By using functional MR imaging to investigate the performance of motor and sensory tasks with the affected and the unaffected hands, we found evidence for increased ipsilateral primary motor cortex activity and reduced transcallosal inhibition. Both these mechanisms are likely to be involved in the genesis of MMs.
