Thromboembolic and Bleeding Events in COVID-19 Patients receiving Extracorporeal Membrane Oxygenation.

Thorac Cardiovasc Surg 2021 Apr 16. Epub 2021 Apr 16.

Department of Thoracic and Cardiovascular Surgery, Uniklinik RWTH Aachen, Aachen, Germany.

Background:  Extracorporeal membrane oxygenation (ECMO) is a potential treatment option in critically ill COVID-19 patients suffering from acute respiratory distress syndrome (ARDS) if mechanical ventilation (MV) is insufficient; however, thromboembolic and bleeding events (TEBE) during ECMO treatment still need to be investigated.

Methods:  We conducted a retrospective, single-center study including COVID-19 patients treated with ECMO. Additionally, we performed a univariate analysis of 85 pre-ECMO variables to identify factors influencing incidences of thromboembolic events (TEE) and bleeding events (BE), respectively. Read More

Highly Conductive and Transparent Electrospun Indium Tin Oxide Nanofibers Calcined by Microwave Plasma.

Nanotechnology 2021 Apr 16. Epub 2021 Apr 16.

Physics, Sichuan University, No. 29 Wangjiang Rd, Wuhou District, Chengdu, Chengdu, Sichuan, 610064, CHINA.

In this work, indium tin oxide (ITO) nanofibers have been prepared by electrospinning of polymers and post-growth microwave plasma calcination (MPC). Interestingly, compared to traditional calcination in furnace, MPC can accelerate the degradation of high polar polymers and improve adhesion of ITO nanofibers to the sapphire substrate. Further characterizations reveal that the ITO nanofibers with diameters of 100-150 nm prepared by MPC at 600℃ can reach a low sheet resistance of 269 Ω/sq and a high transmittance of 90. Read More

Surface-Confinement Assisted Synthesis of Nitrogen-Rich Single Atom Fe-N/C Electrocatalyst with Dual Nitrogen Sources for Enhanced Oxygen Reduction Reaction.

Nanotechnology 2021 Apr 16. Epub 2021 Apr 16.

Chinese Academy of Sciences - Fujian Institute of Research on the Structure of Matter, Fuzhou, CHINA.

The utilization of earth abundant iron and nitrogen doped carbon as a precious-metal-free electrocatalyst for oxygen reduction reaction (ORR) significantly depends on the rational design and construction of desired Fe-Nx moieties on carbon substrates, which however remains an enormous challenge. Herein a typical nanoporous nitrogen-rich single atom Fe-N/C electrocatalyst on carbon nanotube (NR-CNT@FeN-PC) was successfully prepared by using CNT as carbon substrate, polyaniline (PANI) and dicyandiamine (DCD) as N-containing carbonaceous precursor and silica-confinement-assisted pyrolysis, which not only facilitate rich N-doping for the inhibition of the Fe agglomeration and the formation of single atom Fe-Nx sites in carbon matrix, but also generate abundant micropores for enlarging BET specific surface area (up to 1500 m2•g-1). Benefiting from the advanced composition, nanoporous structure and surface hydrophilicity to guarantee the sufficient accessible active sites for ORR, the NR-CNT@FeN-PC catalyst under optimized conditions delivers prominent ORR performance with a half-wave potential (0.

Multi-objective data-driven optimization for improving deep brain stimulation in Parkinson's disease.

J Neural Eng 2021 Apr 16. Epub 2021 Apr 16.

Neurology, Emory University School of Medicine, 12 Executive Park Drive North East, Atlanta, Georgia, 30329, UNITED STATES.

Objective: Deep brain stimulation (DBS) is an effective treatment for Parkinson's disease (PD) but its success depends on a time-consuming process of trial-and-error to identify the optimal stimulation settings for each individual patient. Data-driven optimization algorithms have been proposed to efficiently find the stimulation setting that maximizes a quantitative biomarker of symptom relief. However, these algorithms cannot efficiently take into account stimulation settings that may control symptoms but also cause side-effects. Read More
