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.

Neurological Presentation of Giant Pituitary Tumour Apoplexy: Case Report and Literature Review of a Rare but Life-Threatening Condition.

Background: Giant pituitary adenomas are benign intracranial tumours with a diameter ≥4 cm. Even if hormonally non-functional, they may still cause local extension, leading to symptoms that include mostly gland dysfunction, mass effects, and, much less frequently, apoplexy due to haemorrhage or infarction. Neurological presentation of giant pituitary tumour apoplexy is even more rare and has not been systematically reviewed.

Ischemic stroke shortly after vaccination against SARS-CoV-2: A case-control study.

Background And Purpose: Vaccination against SARS-CoV-2 has been associated with rare occurrences of severe venous thromboses. Very little data exist about arterial ischemic strokes. We have assessed the features of ischemic strokes occurring shortly after vaccination against SARS-CoV-2 in the Cremona area, Italy.

SARS-CoV-2 infection and acute ischemic stroke in Lombardy, Italy.

Objective: To characterize patients with acute ischemic stroke related to SARS-CoV-2 infection and assess the classification performance of clinical and laboratory parameters in predicting in-hospital outcome of these patients.

Methods: In the setting of the STROKOVID study including patients with acute ischemic stroke consecutively admitted to the ten hub hospitals in Lombardy, Italy, between March 8 and April 30, 2020, we compared clinical features of patients with confirmed infection and non-infected patients by logistic regression models and survival analysis. Then, we trained and tested a random forest (RF) binary classifier for the prediction of in-hospital death among patients with COVID-19.

Impact of SARS-CoV-2 on reperfusion therapies for acute ischemic stroke in Lombardy, Italy: the STROKOVID network.

Whether and how SARS-CoV-2 outbreak affected in-hospital acute stroke care system is still matter of debate. In the setting of the STROKOVID network, a collaborative project between the ten centers designed as hubs for the treatment of acute stroke during SARS-CoV-2 outbreak in Lombardy, Italy, we retrospectively compared clinical features and process measures of patients with confirmed infection (COVID-19) and non-infected patients (non-COVID-19) who underwent reperfusion therapies for acute ischemic stroke. Between March 8 and April 30, 2020, 296 consecutive patients [median age, 74 years (interquartile range (IQR), 62-80.

Hypertensive Crisis in Acute Cerebrovascular Diseases Presenting at the Emergency Department: A Narrative Review.

Hypertensive crisis, defined as an increase in systolic blood pressure >179 mmHg or diastolic blood pressure >109 mmHg, typically causes end-organ damage; the brain is an elective and early target, among others. The strong relationship between arterial hypertension and cerebrovascular diseases is supported by extensive evidence, with hypertension being the main modifiable risk factor for both ischemic and hemorrhagic stroke, especially when it is uncontrolled or rapidly increasing. However, despite the large amount of data on the preventive strategies and therapeutic measures that can be adopted, the management of high BP in patients with acute cerebrovascular diseases presenting at the emergency department is still an area of debate.

TMS Correlates of Pyramidal Tract Signs and Clinical Motor Status in Patients with Cervical Spondylotic Myelopathy.

Background: While the association between motor-evoked potential (MEP) abnormalities and motor deficit is well established, few studies have reported the correlation between MEPs and signs of pyramidal tract dysfunction without motor weakness. We assessed MEPs in patients with pyramidal signs, including motor deficits, compared to patients with pyramidal signs but without weakness.

Methods: Forty-three patients with cervical spondylotic myelopathy (CSM) were dichotomized into 21 with pyramidal signs including motor deficit (Group 1) and 22 with pyramidal signs and normal strength (Group 2), and both groups were compared to 33 healthy controls (Group 0).

Cerebral Hemodynamic Changes to Transcranial Doppler in Asymptomatic Patients with Fabry's Disease.

Background: Patients with Fabry's disease (FD) may be asymptomatic or show a spectrum of clinical manifestations, including cerebrovascular disease, mainly affecting posterior circulation. Few and conflicting studies on cerebral blood flow (CBF) velocity by transcranial Doppler sonography (TCD) in asymptomatic FD (aFD) subjects have been published. Our study aims to assess TCD in aFD subjects to identify any preclinical CBF change.

Acetyl-L-Carnitine in Dementia and Other Cognitive Disorders: A Critical Update.

Several studies explored the effects of acetyl-L-carnitine (ALC) in dementia, suggesting a role in slowing down cognitive decline. Nevertheless, in 2003 a systematic review concluded there was insufficient evidence to recommend a clinical use, although a meta-analysis in the same year showed a significant advantage for ALC for clinical scales and psychometric tests. Since then, other studies have been published; however, a critical review is still lacking.

Update on the Neurobiology of Vascular Cognitive Impairment: From Lab to Clinic.

In the last years, there has been a significant growth in the literature exploring the pathophysiology of vascular cognitive impairment (VCI). As an "umbrella term" encompassing any degree of vascular-related cognitive decline, VCI is deemed to be the most common cognitive disorder in the elderly, with a significant impact on social and healthcare expenses. Interestingly, some of the molecular, biochemical, and electrophysiological abnormalities detected in VCI seem to correlate with disease process and progression, eventually promoting an adaptive plasticity in some patients and a maladaptive, dysfunctional response in others.

Migrainous Infarction And Cerebral Vasospasm: Case Report And Literature Review.

Migrainous infarction (MI) is a rare complication of migraines that accounts for 0.5-1.5% of all ischemic strokes.

Age, Height, and Sex on Motor Evoked Potentials: Translational Data From a Large Italian Cohort in a Clinical Environment.

Introduction: Motor evoked potentials (MEPs) to transcranial magnetic stimulation (TMS) are known to be susceptible to several sources of variability. However, conflicting evidences on individual characteristics in relatively small sample sizes have been reported. We investigated the effect of age, height, and sex on MEPs of the motor cortex and spinal roots in a large cohort.

Transcranial Doppler ultrasound in vascular cognitive impairment-no dementia.

Background: Although cerebral white matter lesions (WMLs) are considered as a risk factor for vascular dementia, data on their impact on cerebral hemodynamics are scarce. We test and compare transcranial Doppler (TCD) features in WML patients with or without associated cognitive impairment.

Methods: A sample of non-demented elderly patients with WMLs was consecutively recruited.

18F-Florbetaben PET/CT to Assess Alzheimer's Disease: A new Analysis Method for Regional Amyloid Quantification.

Background And Purpose: While AD can be definitively confirmed by postmortem histopathologic examination, in vivo imaging may improve the clinician's ability to identify AD at the earliest stage. The aim of the study was to test the performance of amyloid PET using new processing imaging algorithm for more precise diagnosis of AD.

Methods: Amyloid PET results using a new processing imaging algorithm (MRI-Less and AAL Atlas) were correlated with clinical, cognitive status, CSF analysis, and other imaging.

Impaired Cerebral Haemodynamics in Vascular Depression: Insights From Transcranial Doppler Ultrasonography.

Late-life depression is a well-known risk factor for future dementia. Increasing evidences also show a link between cerebral hypoperfusion and neurodegeneration, although data on Transcranial Doppler ultrasonography (TCD)-derived measures in patients with "Vascular Depression" (VD) are lacking. The aim of this study was to assess and correlate TCD parameters with cognitive function and severity of subcortical ischemic vascular disease in a sample of VD patients.

Cholinergic circuitry functioning in patients with vascular cognitive impairment--no dementia.

Background: An impairment of central cholinergic activity, as evaluated non-invasively by the short-latency afferent inhibition (SAI) of motor responses evoked by transcranial magnetic stimulation (TMS), was observed in patients with Alzheimer's disease (AD) and amnestic Mild Cognitive Impairment. Conversely, the involvement of central cholinergic neurotransmission in vascular dementia (VaD) is still under debate and data on Vascular Cognitive Impairment--No Dementia (VCI-ND) at risk for future VaD are lacking.

Objective: To test for the first time SAI in patients with VCI-ND.

Effect of a Gluten-Free Diet on Cortical Excitability in Adults with Celiac Disease.

Introduction: An imbalance between excitatory and inhibitory synaptic excitability was observed in de novo patients with celiac disease (CD) in a previous study with Transcranial Magnetic Stimulation (TMS), suggesting a subclinical involvement of GABAergic and glutamatergic neurotransmission in asymptomatic patients. The aim of this investigation was to monitor the eventual changes in the same cohort of patients, evaluated after a period of gluten-free diet.

Methods: Patients were re-evaluated after a median period of 16 months during which an adequate gluten-free diet was maintained.
