Sustainable Carbon Derived from Sulfur-Free Lignins for Functional Electrical and Electrochemical Devices.

Technical lignins, kraft, soda, lignoboost, and hydrolysis lignins were used for the production of carbon particles at different carbonization temperatures, 1000 °C and 1400 °C. The results showed that the lignin source and carbonization temperature significantly influenced the carbon quality and microstructure of the carbon particles. Soda lignin carbonized up to 1400 °C showed higher degree of graphitization and exhibited the highest electrical conductivity of 335 S·m, which makes it suitable for applications, such as electromagnetic interference shielding and conductive composite based structural energy storage devices.

Temporal Trend of Transient Ischemic Attack Management over a 10-Year Period: Data from the Rhône County, France.

Background: Timely recognition and management of transient ischemic attack (TIA) offer the greatest opportunity to prevent subsequent stroke. But variability of TIA management quality exists across hospitals. Under the impetus of national plans, measures were adopted to improve TIA management, including a structured local pathway.

Coronavirus Disease 2019 and Out-of-Hospital Cardiac Arrest: No Survivors.

Objectives: To describe and compare survival among patients with out-of-hospital cardiac arrest as a function of their status for coronavirus disease 2019.

Design: We performed an observational study of out-of-hospital cardiac arrest patients between March 2020 and December 2020. Coronavirus disease 2019 status (confirmed, suspected, or negative) was defined according to the World Health Organization's criteria.

Hetero-Porous, High-Surface Area Green Carbon Aerogels for the Next-Generation Energy Storage Applications.

Various carbon materials have been developed for energy storage applications to address the increasing energy demand in the world. However, the environmentally friendly, renewable, and nontoxic bio-based carbon resources have not been extensively investigated towards high-performance energy storage materials. Here, we report an anisotropic, hetero-porous, high-surface area carbon aerogel prepared from renewable resources achieving an excellent electrical double-layer capacitance.

Impact of a theory-informed and user-centered stroke information campaign on the public's behaviors, attitudes, and knowledge when facing acute stroke: a controlled before-and-after study.

Background: Public awareness of stroke symptoms is a key factor to ensure access to reperfusion strategies in due time. We designed and launched a regional theory-informed and user-centered information campaign and assessed its impact on emergency medical services (EMS) calls for stroke suspicion, time-to-call, and public attitudes and awareness concerning stroke.

Methods: A controlled before-and-after study was conducted during 3 sequential time-periods in 2 separate counties.

Effect of the COVID-19 pandemic on acute stroke reperfusion therapy: data from the Lyon Stroke Center Network.

Background: The coronavirus disease 2019 (COVID-19) pandemic would have particularly affected acute stroke care. However, its impact is clearly inherent to the local stroke network conditions. We aimed to assess the impact of COVID-19 pandemic on acute stroke care in the Lyon comprehensive stroke center during this period.

Choice of Initial Brain Imaging in Patients with Suspected Acute Stroke: STROKE69, a Population-Based Study.

Background: In patients with suspected stroke, brain imaging is recommended in the acute phase for appropriate management and treatment. Both computed tomography (CT) and magnetic resonance imaging (MRI) are considered reasonable choices for initial brain imaging. When both techniques are available, choosing one or the other might be associated with specific factors related either to patients, stroke symptoms, and severity or management organization.
