Abstract BACKGROUND: Meningitis is listed as one of the diseases requiring compulsory notification in Brazil. It can affect all age groups and also has no seasonality. Cases can be recorded in all months of the year and in all states of Brazil. Despite its importance, the obligation of immediate notification may have been compromised by the coronavirus disease 2019 (COVID-19) pandemic. OBJECTIVE: To analyze the immediate impact of the COVID-19 pandemic on compulsory notifications of meningitis in Brazil and its states during the first wave of the pandemic. DESIGN AND SETTING: This was an ecological study involving all confirmed cases of meningitis in Brazil, in its regions and in its states. METHODS: Data for the months from 2015 to 2020 were obtained from the database of the Notifiable Diseases Information System (Sistema de Informação de Agravos de Notificação, SINAN), in the Department of Informatics of the National Health System (Departamento de Informática do Sistema Único de Saúde, DATASUS). The P-score was used to obtain the percentage change in the numbers of cases reported in 2020. RESULTS: A 45.7% reduction in notifications of meningitis in Brazil was observed. Regarding the regions and the states, with the exception of Roraima, all of them showed a negative P-score, with decreasing curves each month. CONCLUSION: The pandemic caused a negative impact on meningitis notifications in Brazil.

RESUMO Objetivo Avaliar as tendências temporais das hospitalizações por Embolia Pulmonar (EP) no Brasil, assim como suas regiões e estados no período entre 2008 e 2019. Métodos Foi realizado um estudo ecológico e de série temporal. Os dados foram obtidos do Sistema de Informação Hospitalar (SIH) do Ministério da Saúde (MS) do Brasil. O modelo de regressão de pontos de inflexão foi aplicado para análises de tendências temporais. As tendências foram classificadas como crescentes, decrescentes ou estacionárias de acordo com a inclinação da linha de regressão. O percentual de variação anual (APC) e Percentual de Variação Médio do Período (AAPC) foram calculados considerando Intervalo de Confiança de 95% (IC 95%) e significância de 5%. Além disso, foram elaborados mapas de distribuição espacial dos indicadores epidemiológicos relacionados à EP no Brasil. Resultados Houve uma tendência crescente na taxa de hospitalização de EP no Brasil, variando de 2,57 em 2008 a 4,44/100.000 em 2019 (AAPC=5,6%; p<0,001). Os custos totais e médios de hospitalização também mostraram uma tendência crescente no país (AAPC=9,2% e 3,0%, respectivamente). Ainda assim, houve uma diminuição na taxa de mortalidade hospitalar (de 21,21% para 17,11%; AAPC=-1,9%; p<0,001). Tendências similares foram observadas na maioria das regiões. O tempo médio de hospitalização no Brasil mostrou uma tendência estacionária. A taxa de hospitalização também aumentou em 18 estados (66,67%). Sete estados mostraram uma diminuição na taxa de mortalidade (25,93%), exceto Roraima, que mostrou uma tendência crescente. Conclusão As hospitalizações de EP representam um grave problema de saúde pública no Brasil, e os padrões temporais aqui observados demonstraram uma tendência crescente em todas as regiões e estados do país.

ABSTRACT Objective To assess the temporal trends of hospitalizations for pulmonary embolism (PE) in Brazil, its regions, and states between 2008 and 2019. Methods An ecological and time series study was conducted. Data were obtained from the Hospital Information System (SIH) of the Brazilian Ministry of Health. The inflection point regression model was applied for temporal trend analyses. Trends were classified as increasing, decreasing, or stationary according to the slope of the regression line. The Annual Percent Charge (APC) and the Average Annual Percent Change (AAPC) were calculated considering a confidence interval of 95% and p-value <0.05. Furthermore, spatial distribution maps of epidemiological indicators related to PE in Brazil were elaborated. Results There was an increasing trend in the hospitalization rate for PE in Brazil, ranging from 2.57 in 2008 to 4.44/100,000 in 2019 (AAPC=5.6%; p<0.001). Total and average hospitalizations costs also showed increasing trend in the country (AAPC=9.2% and 3.0%, respectively). Still, there was a decrease in the in-hospital mortality rate (from 21.21% to 17.11%; AAPC=-1.9%; p<0.001). Similar trends were observed in most regions. The average hospitalization time in Brazil showed a stationary trend. The hospitalization rate has also increased in 18 states (66.67%). Seven states showed a decrease in the mortality rate (25.93%), except for Roraima, which showed an increasing trend. Conclusion Hospitalizations for PE represent a serious public health problem in Brazil and the temporal patterns observed herein demonstrate an increasing trend in all regions and states of the country.

Resumo Fundamento: A pandemia da COVID-19 tem causado um impacto sobre a mortalidade por várias doenças em todo o mundo, especialmente por doenças cardiovasculares (DCVs). O Brasil é um país de dimensões continentais com diferenças significativas na estrutura de saúde entre seus estados. Objetivo: Analisar a mortalidade hospitalar por DCV no sistema público de saúde durante o primeiro ano da pandemia por COVID-19 (2020) no Brasil. Métodos: Este é um estudo ecológico analisando o número absoluto de mortes hospitalares e a taxa de mortalidade hospitalar no Brasil, suas macrorregiões, e unidades federativas. Os dados foram obtidos do Sistema de Informações Hospitalares (SIH) do Ministério da Saúde. O P-escore foi usado para analisar o excesso de mortalidade. O escore compara os eventos observados com os eventos esperados para um dado local e período. O escore-P foi corrigido por um modelo de regressão joinpoint, com um intervalo de confiança de 95% e nível de significância de 5%. Resultados: Houve 93.104 óbitos hospitalares por DCV no Brasil em 2020, o que representa 1495 menos óbitos (escore-P: -1,58) que o esperado. A região centro-oeste apresentou um escore-P positivo, com um aumento de 15,1% no número de mortes. Dez estados apresentaram um maior número de óbitos em 2020. Ainda, observou-se um excesso de 13,3% de mortalidade hospitalar no país como um todo, e um excesso de mortalidade hospitalar em todas as macrorregiões. Conclusões: Houve uma diminuição no número absoluto de óbitos hospitalares, bem como um aumento na taxa de mortalidade por DCV no Brasil em 2020, após o início da pandemia por COVID-19.

Abstract Background: The COVID-19 pandemic has had an impact on mortality from several diseases worldwide, especially cardiovascular diseases (CVD). Brazil is a continent-sized country with significant differences in the health care structure between its federative units. Objective: Analyze in-hospital mortality from CVDs in the Brazilian public health system during the first year of the COVID-19 pandemic (2020). Methods: This is an ecological study analyzing the absolute number of in-hospital deaths and the rate of in-hospital mortality in Brazil, its macro-regions, and federative units. Data were obtained from the Hospital Information System of the Brazilian Ministry of Health. To analyze excess mortality, the P-score was used. It compares the events observed with those expected for a given place and period. The P-score was corrected by the joinpoint regression model, with a 95% confidence interval and 5% significance level. Results: There were 93,104 in-hospital deaths due to CVD in Brazil in 2020, representing 1,495 fewer deaths (P score: −1.58) than expected. The central-west region had a positive P-score, with a 15.1% increase in the number of deaths. Ten federative units showed a greater number of deaths in 2020. There was also a 13.3% excess in-hospital mortality at the country level, and an excess in-hospital mortality in all macro-regions. Conclusions: There was a decrease in the absolute number of in-hospital deaths, as well as an increase in in-hospital mortality from CVD in Brazil, in 2020, after the COVID-19 pandemic onset.

Abstract Introduction: The present study intends to systematically review the literature on the use of extracorporeal membrane oxygenation (ECMO) in patients with coronavirus disease 2019 (COVID-19). Methods: The research was carried out according to the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). Studies were selected from PubMed/MEDLINE and LILACS databases between December 2019 and May 17 2020, using the descriptors "ECMO AND COVID-19", "Extracorporeal Membrane Oxygenation AND COVID-19", "ECLS AND COVID-19", and "Extracorporeal Life Support AND COVID-19". Exclusion criteria were government epidemiological bulletins, comments, literature reviews, and articles without full access to content. Results: Two hundred and thirty-three scientific productions were found, however only 18 did not met the exclusion criteria and could be included in this study, amouting to a total of 911 patients - 624 (68.5%) men, 261 (28.6%) women, and 26 (2.8%) without sex information. The mean age of the patients was 53.7 years. ECMO was necessary in 274 (30.1%) people (200 [73%] submitted to veno-venous ECMO, nine [3.3%] to veno-arterial ECMO, and seven [2.5%] moved between these two types or needed a more specific ECMO according to the disease prognosis). Five studies did not specify the type of ECMO used, amounting 57 (20.8%) patients. Five patients (1.8%) were discharged, 77 (28.1%) died, 125 (45.6%) remained hospitalized until publication time of their respective studies, and 67 patients (24.4%) had no outcome information. Conclusion: It is evident that more research, covering larger populations, must be carried out in order to clearly elucidate the role of ECMO in the treatment of COVID-19.
