COVID‐19 has a broad spectrum of clinical manifestations associated with the host immune response heterogeneity. Despite the advances in COVID‐19 research, it is still crucial to seek a panel of molecular markers that enable accurate stratification of COVID‐19 patients. Here, we performed a study that combined analysis of blood transcriptome, demographic data, clinical aspects and laboratory findings from 66 participants classified into different degrees of COVID‐19 severity and healthy subjects. We identified a perturbation in blood‐leukocyte transcriptional profile associated with COVID‐19 aggravation, which was mainly related to processes that disfavoured lymphocyte activation and favoured neutrophil activation. This transcriptional profile stratified patients according to COVID‐19 severity. Hence, it enabled identification of a turning point in transcriptional dynamics that distinguished disease outcomes and non‐hospitalized from hospitalized moderate patients. Central genes of this unique neutrophil signature were S100A9, ANXA3, CEACAM6, VNN1, OLFM4, IL1R2, TCN1 and CD177. Our study indicates the molecular changes that are linked with the differing clinical aspects presented by humans when suffering from COVID‐19, which involve neutrophil activation.

Neste trabalho, objetivou-se identificar podcasts aplicados à educação ou que pudessem ser utilizados com esta finalidade, que tivessem a pandemia da COVID-19 como temática central ou que englobassem o assunto em seus conteúdos, com vistas a sugerir o uso desta ferramenta como metodologia complementar no processo de ensino-aprendizagem. Foram identificados e avaliados 36 podcasts conforme a taxonomia proposta. Destes, 19 compuseram a amostra final. Observou-se que os conteúdos abrangiam diversos níveis de ensino, o que demonstra potencial aplicação frente aos novos desafios educacionais. Não obstante, os podcasts atravessam diferentes áreas do conhecimento permitindo uma interdisciplinaridade mais efetiva. Entende-se assim que os podcasts podem ser utilizados em diferentes momentos e com diferentes metodologias de ensino. Além disso, a ferramenta possibilita a inclusão de diferentes peculiaridades no processo de ensino-aprendizagem e torna o processo pedagógico plural.
