Pediatric acute ischemic strokes are themselves rare and with very few large vessel occlusion related acute ischemic strokes attributed to COVID-19 described in the literature as of date. COVID-19 pandemic has contributed to acute stroke care delays across the world and with pediatric endovascular therapy still in its infancy, it poses a great challenge in facilitating good outcomes in children presenting with acute ischemic strokes in the setting of COVID-19. We present a pediatric patient who underwent endovascular therapy for an internal carotid artery occlusion related acute ischemic stroke in the setting of active COVID-19 and had an excellent outcome thanks to a streamlined stroke pathway involving the vascular neurology, neuro-interventional, neurocritical care, and anesthesiology teams.
Circulating Endothelial Progenitor Cells (EPCs) predict cardiovascular outcomes in patients with coronary disease. However, the predictive value of EPCs after ischemic stroke is not well established. We aimed to study the prognostic role of EPCs in patients with acute ischemic stroke and carotid atherosclerosis, focusing on post-stroke functional outcome and stroke recurrences.

We studied consecutive adult patients with an acute (<7 days) anterior circulation ischemic stroke and carotid atherosclerosis. Cardioembolic strokes were excluded. We measured circulating EPCs by flow cytometry (CD34+/CD133+/KDR+) at inclusion (7±1 days after stroke) and at one year of follow-up. At three months and at one year we registered the modified Rankin Scale score, stroke recurrences and coronary syndromes during the follow-up.

We studied 80 patients with a mean age of 74.3±10.4 years. ACY241 We divided the population in tertiles according to the EPCs count. At three months we observed a favorable outcome in 25/36 (69.4%) patients in the lowest, 19/22 (86.4%) in the medium and 21/22 (95.5%) in the highest tercile (p=0.037). In the multivariable analysis a higher EPCs count was associated with favorable functional outcome after adjusting for age and baseline NIHSS score (OR=3.61, 95%CI 1.34-9.76; p=0.011). This association persisted at one year of follow-up. We did not find association between counts of EPCs and stroke recurrence.

In patients with acute ischemic stroke and carotid atherosclerosis, a higher count of EPCs was associated with favorable functional outcome in the mid and long-term follow-up. Counts of EPCs did not predict stroke recurrences.

Treating high-risk transient ischemic attack (TIA) with dual antiplatelet therapy (DAPT) reduces subsequent ischemic stroke risk yet current rates of clopidogrel-aspirin treatment are uncertain.

We conducted a retrospective cohort study of consecutive TIA patients who presented to any of the four emergency departments (ED) of a single urban health system from 1/1/2018-3/1/2020. Medical record review was used to describe the cohort and assess clopidogrel-aspirin treatment. Patient eligibility for clopidogrel-aspirin was determined using relevant criteria from the Platelet-Oriented Inhibition in New TIA and Minor Ischemic Stroke (POINT) Trial. Comparisons among eligible patients who received versus did not receive clopidogrel-aspirin were conducted using t-test, chi-squared, and Mann-Whitney as indicated.

We identified 248 TIA patients of whom 95 met eligibility criteria for clopidogrel-aspirin treatment. Among these 95 patients, mean age was 69.5 (SD 12), 68.4% were women, and median ABCD
score was 5 (nity ED, though under treatment was evident at all sites.Neuroscience and artificial intelligence (AI) share a long history of collaboration. Advances in neuroscience, alongside huge leaps in computer processing power over the last few decades, have given rise to a new generation of in silico neural networks inspired by the architecture of the brain. These AI systems are now capable of many of the advanced perceptual and cognitive abilities of biological systems, including object recognition and decision making. Moreover, AI is now increasingly being employed as a tool for neuroscience research and is transforming our understanding of brain functions. In particular, deep learning has been used to model how convolutional layers and recurrent connections in the brain's cerebral cortex control important functions, including visual processing, memory, and motor control. Excitingly, the use of neuroscience-inspired AI also holds great promise for understanding how changes in brain networks result in psychopathologies, and could even be utilized in treatment regimes. Here we discuss recent advancements in four areas in which the relationship between neuroscience and AI has led to major advancements in the field; (1) AI models of working memory, (2) AI visual processing, (3) AI analysis of big neuroscience datasets, and (4) computational psychiatry.
Our objectives were to assess in perinatal women the most effective methods used to meet social support needs during COVID-19, the impact of COVID-19 on self-reported social support levels, and how perceived change in social support related to distress, depression, and mental health.

One-time survey administered from April to August 2020 SETTING Online PARTICIPANTS Pregnant and postpartum women with infants less than 6 months of age MEASUREMENT AND FINDINGS Participants indicated the methods they used to meet social support needs during COVID-19. They self-rated their social support level pre- and during pandemic and their distress, depressive symptoms, and mental health changes on a Likert scale. Out of 1142 participants, the most effective methods for obtaining social support during the pandemic were virtual means (e.g. video call) and interaction with friends. There was a significant difference in distribution of self-reported levels of social support before and during the pandemic, with more respondents reporting a decrease in support. Decreases in social support were associated with higher distress levels, higher levels of depressive symptoms, and poorer mental health.

Perinatal women reported decreased social support during the COVID-19 pandemic which was associated with poorer mental health. Using virtual means of social support and support provided by friends had the largest positive effect on perceived social support levels.

Interventions using virtual support means from friends may be helpful to improve social support and mental health in this population.

The aim was to develop and establish the psychometric properties of the Pandemic-Related Pregnancy Stress Scale (PREPS) in European Spanish speaking pregnant women in Spain.

A cross section design using a non-random sample of 206 women completed the questionnaire during the first COVID-19 pandemic lockdown from April to June 2020 in Spain. Psychological, sociodemographic and obstetric factors and the new PREPS were collected.

Bartlett's test of sphericity (χ
(105)=580.36, p < .001), and KMO=.79 confirmed appropriateness for factor analysis of the PREPS. Confirmatory factor analyses based on the factor structure of the original USA English version of this instrument confirmed three factors - Preparedness Stress (7 items), Perinatal Infection Stress (5 items), and Positive Appraisal (3 items). The 15-item version of the PREPS demonstrates internal consistency and reliability are adequate (α > .77), and for F1 - Preparedness (α > .65), for F2 - Infection (α > 0.60) and for F3 - Positive appraisal (α > .55). The three factors exhibited good inter-item correlations, (F1 - Preparedness .21; F2 - Infection .23, and F3 - Positive Appraisal .29). Convergent validity was examined through the Pearson's correlation coefficients of the PREPS with the Perceived Stress Scale (PSS) and the Prenatal Distress Questionnaire (PDQ). Correlation between PREPS total and PSS was high, and moderate with PDQ (p < .05).

The psychometric properties of the Spanish version of the PREPS make it a valuable psychological measure to assess pandemic-related stress among pregnant women.

The Vicon motion capture system is a popular tool for biomechanics, gait analysis, and robotics. The ASCII files produced are large and complex, making them difficult to read and analyze.

This paper presents two packages, the Vicon Toolkit Package and the Gait Analysis Toolkit Package. They use an open-source framework for ingesting, parsing, and analyzing Vicon mocap data and performing gait analysis. The package that handles the Vicon analysis is separated from the Gait Analysis package to allow for abstraction and expansion, and is not specific only to the Vicon system.

Our Vicon Toolkit provides tools to work directly with the marker data and other Vicon Nexus system outputs. The Gait Toolkit provides tools for performing gait analysis, EMG filtering, and learning trajectories. The packages are built upon a core library, GaitCore, that provides unified objects to perform operations and store data.

This paper will show how to use the packages' tools and the expected outputs. All the tools are open-source and written in Python3.x for ease of use and access to other powerful libraries.

This review aimed to bring together the different types of scientific articles on vitamin d-fortified bread. The databases used for the research were PUBMED, WEB of SCIENCE and SCOPUS; all original indexed studies written in English, published between January 2000 and March 2021, were considered. Three important points were identified i) theoretical models of fortification; ii) stability, bioaccessibility, and bioavailability studies of vitamin d-fortified breads; and iii) clinical effects of vitamin d-fortified breads. This review showed that vitamin d-fortified bread is a promising vehicle for fortification strategy effects, leading to increased serum concentrations of 25(OH)D and decreased parathyroid hormone. However, further studies are needed to elucidate the effects and effectiveness of this fortification strategy in the prevention/treatment of vitamin D deficiency.
