Use of COVID-19 Convalescent Plasma for Treatment of Symptomatic SARS-CoV-2 Infection at a Children's Hospital: A Contribution to a Still Inadequate Body of Evidence.

Data on COVID-19 convalescent plasma (CCP) safety and efficacy in children and young adults are limited. This single-center prospective, open-label trial evaluates CCP safety, neutralizing antibody kinetics, and outcomes in children and young adults with moderate/severe COVID-19 (April 2020-March 2021). A total of 46 subjects received CCP; 43 were included in the safety analysis (SAS); 7.

Safety and Antibody Kinetics of COVID-19 Convalescent Plasma for the Treatment of Moderate to Severe Cases of SARS-CoV-2 Infection in Pediatric Patients.

Background: Therapies against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and its life-threatening respiratory infection coronavirus disease 2019 (COVID-19) have been evaluated, including COVID-19 convalescent plasma (CCP). Multiple large reports of CCP treatment in adults exist. Pediatric data on CCP safety and efficacy are limited.

Tissue factor inflammatory response regulated by promoter genotype and p38 MAPK in neonatal vs. adult microvascular endothelial cells.

Objective And Design: Variable tissue factor (TF) expression by human microvascular endothelial cells (HMVEC) may be regulated by two promoter haplotypes, distinguished by an 18-basepair deletion (D) or insertion (I) at -1,208. We sought to determine the relationship between these haplotypes and interleukin-1α (IL-1α)-induced TF expression in neonatal versus adult HMVEC.

Results: IL-1-stimulated TF mRNA, protein, and activity were significantly higher in neonatal compared to adult D/D donors.

Diet order entry by registered dietitians results in a reduction in error rates and time delays compared with other health professionals.

In January 2009, registered dietitians (RDs) at St Michael's Hospital (Toronto, Ontario, Canada) were granted approval for nonmedication order entry of physician-approved nutrition-related orders for the patients to whom RDs provided care. The aim of this project was to document any changes in the numbers and types of diet order errors and time delays that were associated with this policy change. A retrospective chart audit was conducted to document the error rate in 672 nutrition-related orders placed before, and in 633 orders placed after, implementation of RD diet order entry on high-risk inpatient units.

Experimental Investigation on Spontaneously Active Hippocampal Cultures Recorded by Means of High-Density MEAs: Analysis of the Spatial Resolution Effects.

Based on experiments performed with high-resolution Active Pixel Sensor microelectrode arrays (APS-MEAs) coupled with spontaneously active hippocampal cultures, this work investigates the spatial resolution effects of the neuroelectronic interface on the analysis of the recorded electrophysiological signals. The adopted methodology consists, first, in recording the spontaneous activity at the highest spatial resolution (interelectrode separation of 21 mum) from the whole array of 4096 microelectrodes. Then, the full resolution dataset is spatially downsampled in order to evaluate the effects on raster plot representation, array-wide spike rate (AWSR), mean firing rate (MFR) and mean bursting rate (MBR).
