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.

Side-Selective Solid-Phase Metallaphotoredox -Arylation of Peptides.

Postsynthetic diversification of peptides through selective modification of endogenous amino acid side chains has enabled significant advances in peptide drug discovery while expanding the biological and medical chemistry space. However, current tools have been focused on the modification of reactive polar and ionizable side chains, whereas the decoration of aromatic systems (e.g.

A dinuclear copper(II) complex with photoswitchable catechol oxidation activity.

In this study, we report the first example of a photoswitchable copper complex with catechol oxidase activity. The distance between the two copper centres is optimal for catalytic catechol oxidation in the -configuration. Thus, the activity of the catalyst is increased compared to its -configuration.

Excited State Anions in Organic Transformations.

Utilizing light is a smart way to fuel chemical transformations as it allows the energy to be selectively focused on certain molecules. Many reactions involving electronically excited species proceed via open-shell intermediates, which offer novel and unique routes to expand the hitherto used synthetic toolbox in organic chemistry. The direct conversion of non-prefunctionalized, less activated compounds is a highly desirable goal to pave the way towards more sustainable and atom-economic chemical processes.

Light-Triggered Catalytic Asymmetric Allylic Benzylation with Photogenerated -Nucleophiles.

Herein is reported the asymmetric allylic benzylation of Morita-Baylis-Hillman (MBH) carbonates with 2-methylbenzophenone (MBP) derivatives as nonstabilized photogenerated -nucleophiles. The dual activation of both reaction partners, chiral Lewis-base activation of the electrophile and light activation of the nucleophile, enables the stereoselective installation of benzyl groups at the allylic position to forge tertiary and quaternary carbon centers.

Thrombolysis in elderly stroke patients in Italy (TESPI) trial and updated meta-analysis of randomized controlled trials.

Background: Since its approval, the use of alteplase had been limited to patients aged ≤80 years.

Aims: TESPI trial had been designed to evaluate whether alteplase treatment within 3 h in patients with acute ischemic stroke aged >80 years resulted in favorable benefit/risk ratio compared with standard care. The meta-analysis of randomized controlled trials was updated to put findings in the context of all available evidence.

Lack of Temporal Impairment in Patients With Mild Cognitive Impairment.

In the present study, we investigate possible temporal impairment in patients with mild cognitive impairment (MCI) and the amount of temporal distortions caused by the presentation of emotional facial expressions (anger, shame, and neutral) in MCI patients and controls. Twelve older adults with MCI and 14 healthy older adults were enrolled in the present study. All participants underwent a complete neuropsychological evaluation.

Ratio Aβ1-42:p-Tau: a Possible Diagnostic Tool in Differentiating Dementias.

Background: Patients with Alzheimer's disease (AD) present a typical biochemical profile of biomarkers: low concentration of β amyloid 1-42 (Aβ1-42), high concentration of total Tau (t-Tau) and phosphorylated Tau at threonine 181 (p-Tau). Several neurodegenerative diseases may overlap with AD, both in regards to clinical symptoms and neuropathology. Many data suggest that Alzheimer's disease (AD) pathophysiology can be identified using biomarkers.

Herpes simplex virus encephalitis temporally associated with dimethyl fumarate-induced lymphopenia in a multiple sclerosis patient.

Background: Dimethyl fumarate (DMF) is approved as first line therapy for relapsing-remitting multiple sclerosis (RRMS). In some (3%) patients, DMF induces a marked lymphopenia. Herpes simplex encephalitis (HSE) may occur in lymphopenic subjects under treatment with immune-suppressive drugs.

Diagnostics of autoimmune encephalitis associated with antibodies against neuronal surface antigens.

This document presents the guidelines for testing antibodies against neuronal surface antigens that have been developed following a consensus process built on questionnaire-based surveys, internet contacts, and discussions at workshops of the sponsoring Italian Association of Neuroimmunology (AINI) congresses. Essential clinical information on autoimmune encephalitis associated with antibodies against neuronal surface antigens, indications and limits of testing for such antibodies, instructions for result interpretation, and an agreed laboratory protocol (Appendix A) are reported for the communicative community of neurologists and clinical pathologists.

Analysis of combined CSF biomarkers in AD diagnosis.

Background: The new proposed diagnostic criteria for early diagnosis of Alzheimer's Disease (AD) underline the value of cerebrospinal fluid (CSF) biomarkers. The first aim of the study was to determine the diagnostic accuracy of CSF biomarker Abeta1-42, T-tau, and P-tau in differentiating AD patients in our cohort by means of "pure" biomarkers and in form of a combined analysis of these biomarkers. The second aim of the study was to determine the diagnostic accuracy of these markers for predicting incipient AD in patients with mild cognitive impairment (MCI).

Systolic blood pressure contributes to intracerebral haemorrhage after thrombolysis for ischemic stroke.

The frequency and risk factors for intracerebral haemorrhage (ICH) after ischemic stroke are well-known. ICH frequency is increased by the use of antithrombotic or thrombolytic drugs. Several experimental studies have demonstrated a relationship between ICH and hypertension after fibrinolysis, but the optimal blood pressure levels in patients treated with recombinant tissue plasminogen activator (rTPA) are as yet unknown.
