Technical performance of a lateral flow immunoassay for detection of anti-SARS-CoV-2 IgG in the outpatient follow-up of non-severe cases and at different times after vaccination: comparison with enzyme and chemiluminescent immunoassays.

This study assessed the technical performance of a rapid lateral flow immunochromatographic assay (LFIA) for the detection of anti-SARS-CoV-2 IgG and compared LFIA results with chemiluminescent immunoassay (CLIA) results and an in-house enzyme immunoassay (EIA). To this end, a total of 216 whole blood or serum samples from three groups were analyzed: the first group was composed of 68 true negative cases corresponding to blood bank donors, healthy young volunteers, and eight pediatric patients diagnosed with other coronavirus infections. The serum samples from these participants were obtained and stored in a pre-COVID-19 period, thus they were not expected to have COVID-19.

Fast, cheap and feasible: Implementation of pediatric telemedicine in a public hospital during the Covid-19 pandemic.

Objective: In Brazil, telemedicine was allowed as an exception during the coronavirus disease (COVID-19) pandemic. Despite its recognized value and availability, telemedicine is not universally used, suggesting that some barriers prevent its adoption and acceptance within the community. This study aims to describe the implementation of a low-cost telemedicine service in a pediatric hospital in Brazil.

Severe clinical spectrum with high mortality in pediatric patients with COVID-19 and multisystem inflammatory syndrome.

Objectives: To assess the outcomes of pediatric patients with laboratory-confirmed coronavirus disease (COVID-19) with or without multisystem inflammatory syndrome in children (MIS-C).

Methods: This cross-sectional study included 471 samples collected from 371 patients (age<18 years) suspected of having severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The study group comprised 66/371 (18%) laboratory-confirmed pediatric COVID-19 patients: 61 (92.

Higher burnout scores in paediatric residents are associated with increased brain activity during attentional functional magnetic resonance imaging task.

Aim: Burnout syndrome is common in healthcare workers. We evaluated its prevalence in paediatric residents and investigated its influence on cerebral function correlations, using functional magnetic resonance imaging (MRI), when they carried out an attentional paradigm.

Methods: This cross-sectional descriptive study involved 28 residents from the Department of Paediatrics at the University of São Paulo.
