Canadian Pediatric Oncology Nurses' Perspectives on Implementation of the Children's Oncology Group KidsCare Customized App.

Canada represents half of the Children's Oncology Group (COG) sites that have opted to customize content for families within the COG KidsCare app. It was unclear how many sites proceeded with developing and inputting customized content and how well the app and customized content were implemented into practice. This raised concerns that Canadian families were unaware of this new digital resource and did not have equitable access to customized content.

"A Most Equitable Drug": How the Clinical Studies of Convalescent Plasma as a Treatment for SARS-CoV-2 Might Usefully Inform Post-Pandemic Public Sector Approaches to Drug Development.

Interventional clinical studies of convalescent plasma to treat COVID-19 were predominantly funded and led by public sector actors, including blood services operators. We aimed to analyze the processes of clinical studies of convalescent plasma to understand alternatives to pharmaceutical industry biopharmaceutical research and development, particularly where public sector actors play a dominant role. We conducted a qualitative, critical case study of purposively sampled prominent and impactful clinical studies of convalescent plasma during 2020-2021.

A critical contribution in a time of crisis: Examining motivations and deterrents to COVID-19 convalescent plasma donation and future donation intentions among prospective Canadian donors.

Objectives: To understand motivations and deterrents to donate COVID-19 convalescent plasma for a clinical trial and determine whether they predict intention to donate source plasma.

Background: During the COVID-19 pandemic, Canadian Blood Services was involved in three nationally coordinated convalescent plasma clinical trials, requiring the recruitment of several thousand prospective convalescent plasma donors. Understanding the motivations and deterrents of donors in the unique context of a clinical trial and ongoing pandemic can inform recruitment for source plasma donation beyond a clinical trial.

Genome-based taxonomic framework for the class Negativicutes: division of the class Negativicutes into the orders Selenomonadales emend., Acidaminococcales ord. nov. and Veillonellales ord. nov.

The class Negativicutes is currently divided into one order and two families on the basis of 16S rRNA gene sequence phylogenies. We report here comprehensive comparative genomic analyses of the sequenced members of the class Negativicutes to demarcate its different evolutionary groups in molecular terms, independently of phylogenetic trees. Our comparative genomic analyses have identified 14 conserved signature indels (CSIs) and 48 conserved signature proteins (CSPs) that either are specific for the entire class or differentiate four main groups within the class.

Comparative proteome analysis of Acidaminococcus intestini supports a relationship between outer membrane biogenesis in Negativicutes and Proteobacteria.

The presence of bona fide outer membranes in members of the class Negativicutes is anomalous as phylogenetic analyses place this class within the phylum Firmicutes. To explore the relationships of a representative member of Negativicutes, we have performed a whole proteome BLAST analysis of Acidaminococcus intestini, which indicates that a substantial proportion (7 %) of the A. intestini proteome is closely related to sequences from members of the phylum Proteobacteria.
