Clinical characteristics and risk factors for death among hospitalised children and adolescents with COVID-19 in Brazil: an analysis of a nationwide database.

BACKGROUND: COVID-19 is usually less severe and has lower case fatality in children than in adults. We aimed to characterise the clinical features of children and adolescents hospitalised with laboratory-confirmed SARS-CoV-2 infection and to evaluate the risk factors for COVID-19-related death in this population. METHODS: We did an analysis of all patients younger than 20 years who had quantitative RT-PCR-confirmed COVID-19 and were registered in the Influenza Epidemiological Surveillance Information System (SIVEP-Gripe, a nationwide surveillance database of patients admitted to hospital with severe acute respiratory disease in Brazil), between Feb 16, 2020, and Jan 9, 2021. The primary outcome was time to recovery (discharge) or in-hospital death, evaluated by competing risks analysis using the cumulative incidence function. FINDINGS: Of the 82 055 patients younger than 20 years reported to SIVEP-Gripe during the study period, 11 613 (14·2%) had available data showing laboratory-confirmed SARS-CoV-2 infection and were included in the sample. Among these patients, 886 (7·6%) died in hospital (at a median 6 days [IQR 3-15] after hospital admission), 10 041 (86·5%) patients were discharged from the hospital, 369 (3·2%) were in hospital at the time of analysis, and 317 (2·7%) were missing information on outcome. The estimated probability of death was 4·8% during the first 10 days after hospital admission, 6·7% during the first 20 days, and 8·1% at the end of follow-up. Probability of discharge was 54·1% during the first 10 days, 78·4% during the first 20 days, and 92·0% at the end of follow-up. Our competing risks multivariate survival analysis showed that risk of death was increased in infants younger than 2 years (hazard ratio 2·36 [95% CI 1·94-2·88]) or adolescents aged 12-19 years (2·23 [1·84-2·71]) relative to children aged 2-11 years; those of Indigenous ethnicity (3·36 [2·15-5·24]) relative to those of White ethnicity; those living in the Northeast region (2·06 [1·68-2·52]) or North region (1·55 [1·22-1·98]) relative to those in the Southeast region; and those with one (2·96 [2·52-3·47]), two (4·96 [3·80-6·48]), or three or more (7·28 [4·56-11·6]) pre-existing medical conditions relative to those with none. INTERPRETATION: Death from COVID-19 was associated with age, Indigenous ethnicity, poor geopolitical region, and pre-existing medical conditions. Disparities in health care, poverty, and comorbidities can contribute to magnifying the burden of COVID-19 in more vulnerable and socioeconomically disadvantaged children and adolescents in Brazil.

Science funding crisis in Brazil and COVID-19: deleterious impact on scientific output.

The Brazilian scientific community and health care workers are working hard to provide support for the political health measures to deal with this unprecedented crisis of the COVID-19 pandemic. Paradoxically, while the society is looking forward for an immediate response of the scientific community, Brazilian scientists are facing a dramatic reduction in financial support for research and graduate programs.

Profile and scientific production of CNPq researchers in Nephrology and Urology.

OBJECTIVE: This study aimed at evaluating the profile and scientific production of researchers in Nephrology and Urology, receiving grants in the area of Clinical Medicine from the Brazilian National Research Council. METHODS: The standardized online curriculum vitae (Curriculum Lattes) of 39 researchers in Medicine receiving grants in the 2006-2008 triennium were included in the analysis. The variables analyzed were: gender, affiliation, time from completion of the PhD program, scientific production, and supervision of undergraduate students, and master's and PhD programs. RESULTS: Males (74.4%) and category 2 grants (56.4%) predominated. The following three Brazilian states are responsible for 90% of the researchers: São Paulo (28; 71.8%); Rio Grande do Sul (4; 10.3%); and Minas Gerais (3; 7.7%). Four institutions are responsible for 70% of the researchers: UNIFESP (14; 36%); USP (8; 20.5%); UFMG (3, 7.7%); and UNICAMP (3; 7.7%). Considering the academic career, the assessed researchers published 3,195 articles in medical journals, with a median of 75 articles per researcher (QI = 52-100). The researchers received a total of 25,923 citations at the database Web of Science®, with a median of 452 citations per researcher (QI = 161-927). The average number of citations per article was 13.8 citations (SD = 11.6). CONCLUSIONS: The Southeastern region of Brazil concentrates researchers in Nephrology and Urology. Our study has shown an increase in the scientific production of most researchers in the last five years. By knowing the profile of researchers in Nephrology and Urology, more effective strategies to encourage the scientific production and the demand for resources to finance research projects can be defined.

Perfil e produção científica dos pesquisadores do CNPq nas áreas de nefrologia e urologia / Profile and scientific production of CNPq researchers in nephrology and urology

OBJETIVO: O objetivo deste estudo foi avaliar o perfil e a produção científica de pesquisadores de Nefrologia e Urologia, cadastrados como bolsistas de produtividade no Conselho Nacional de Desenvolvimento Científico e Tecnológico. MÉTODOS: Os currículos Lattes de 39 pesquisadores com bolsas ativas no triênio 2006 a 2008 foram incluídos na análise. As variáveis de interesse foram: sexo, instituição, tempo de doutoramento, artigos publicados, e orientação de alunos de graduação, mestres e doutores. RESULTADOS: Houve uma predominância do gênero masculino (74,4 por cento) e de bolsistas na categoria 2 (56,4 por cento). Três estados da federação são responsáveis por 90 por cento dos pesquisadores: SP (28; 71,8 por cento), RS (4; 10,3 por cento) e MG (3; 7,7 por cento). Quatro instituições são responsáveis por 70 por cento dos pesquisadores: UNIFESP (14; 36 por cento), USP (8; 20,5 por cento), UFMG (3, 7,7 por cento) e UNICAMP (3; 7,7 por cento). No total da carreira acadêmica, os pesquisadores em Nefrourologia publicaram 3.195 artigos em periódicos, sendo a mediana de 75 artigos por pesquisador (IQ = 52 - 100). Os pesquisadores receberam um total de 25.923 citações na base de dados Web of Science®, sendo a mediana por pesquisador de 452 citações (IQ = 161 - 927). A média de citações por artigo foi de 13,8 citações (DP = 11,6). CONCLUSÕES: Há uma concentração dos pesquisadores na região Sudeste. Neste estudo, pode ser observado um aumento da produção científica entre a maioria dos pesquisadores nos últimos cinco anos. Através do conhecimento do perfil dos pesquisadores das áreas de Nefrologia e Urologia podem ser definidas, de maneira mais eficaz, estratégias para incentivar a produção científica e a demanda de recursos para o financiamento de projetos de pesquisa.
