Factors associated with hospitalizations and deaths of pregnant women from Paraná due to COVID-19: a cross-sectional study.

OBJECTIVE: To analyze the factors associated with hospitalization in the ward and intensive care unit (ICU), and with death from COVID-19 in pregnant women with confirmed cases. METHODS: Observational, cross-sectional study, carried out with data from pregnant women with a confirmed case of COVID-19 from the Influenza Epidemiological Surveillance Information System and the Paraná's state COVID-19 notification system. The association between the independent and dependent variables (hospitalization in the ward and ICU, and death) was investigated using the Poisson regression model with robust variance. RESULTS: 4,719 pregnant women comprised the study population. 9.6 and 5.1% were hospitalized in wards and ICU, respectively. 1.9% died. There was an association between advanced maternal age and hospitalization in wards (PR=1.36; 95%CI 1.10-1.62) and ICU (PR=2.25; 95%CI 1.78-2.71), and death (PR=3.22; 95%CI 2.30-4.15). An association was found between the third trimester and hospitalization in wards (PR=5.06; 95%CI 2.82-7.30) and ICU (PR=6.03; 95%CI 3.67-8.39) and death (PR=13.56; 95%CI 2.90-24.23). The second trimester was associated with ICU admission (PR=2.67; 95%CI 1.36-3.99). Pregnant women with cardiovascular disease had a higher frequency of hospitalization in wards (PR=2.24; 95%CI 1.43-3.05) and ICU (PR=2.66; 95%CI 1.46-3.87). Obesity was associated with ICU admission (PR=3.79; 95%CI 2.71-4.86) and death (PR=5.62; 95%CI 2.41-8.83). CONCLUSIONS: Advanced maternal age, the end of the gestational period and comorbidities were associated with severe COVID-19.

RESUMO Objetivo: Analisar os fatores associados à hospitalização em enfermaria e unidade de terapia intensiva (UTI), e ao óbito pela COVID-19 em gestantes com caso confirmado. Métodos: Pesquisa observacional, transversal, realizada com dados de gestantes com caso confirmado para COVID-19 provenientes do Sistema de Informação de Vigilância Epidemiológica da Gripe e do Sistema Estadual Notifica COVID-19, do Paraná. Investigou-se a associação entre variáveis independentes e dependentes (hospitalização em enfermaria e UTI, e óbito) pelo modelo de regressão de Poisson com variância robusta. Resultados: 4.719 gestantes compuseram a população do estudo; 9,6 e 5,1% foram hospitalizadas em enfermaria e UTI, respectivamente; 1,9% evoluíram para óbito. Houve associação entre a idade materna avançada e internação em enfermaria (RP=1,36; IC95% 1,10-1,62) e UTI (RP=2,25; IC95% 1,78-2,71), e óbito (RP=3,22; IC95% 2,30-4,15). Verificou-se associação entre o terceiro trimestre gestacional e hospitalização em enfermaria (RP=5,06; IC95% 2,82-7,30) e UTI (RP=6,03; IC95% 3,67-8,39) e óbito (RP=13,56; IC95% 2,90-24,23). O segundo trimestre associou-se à internação em UTI (RP=2,67; IC95% 1,36-3,99). Gestantes com cardiopatia apresentaram maior frequência de hospitalização em enfermaria (RP=2,24; IC95% 1,43-3,05) e UTI (RP=2,66; IC95% 1,46-3,87). A obesidade foi associada à admissão em UTI (RP=3,79; IC95% 2,71-4,86) e ao óbito (RP=5,62; IC95% 2,41-8,83). Conclusão: A idade materna avançada, o final do período gestacional e comorbidades foram fatores associados a quadros graves de COVID-19.

Temporal-spatial analysis of hospitalizations for bronchiolitis in Brazil: prediction of epidemic regions and periods for immunization against the Respiratory Syncytial Virus.

OBJECTIVE: Due to the high cost and short term of passive immunization against the respiratory syncytial virus, the main virus causing acute viral bronchiolitis, predicting epidemic regions and epidemic months is extremely important. The objective of this study is to identify both the month when the seasonal peak begins and Brazilian regions and states with the highest incidence of monthly hospitalizations due acute viral bronchiolitis. METHODS: Based on data obtained from DATASUS, monthly hospitalization rates due acute viral bronchiolitis were calculated for every 10,000 live births to children under 12 months of age in all Brazilian states and the Federal District between 2000 and 2019. Seasonal autoregressive integrated moving average models were estimated to forecast monthly hospitalization rates in 2020. RESULTS: A higher incidence of hospitalizations was found for male children, especially under six months of age. As for Brazilian regions, between 2000 and 2019, the South region registered the highest incidence of hospitalizations, followed by the Southeast, Midwest, North and Northeast regions, in this order. Considering the seasonal peak, the period between March and July 2020 comprised the highest expected hospitalization rates. CONCLUSIONS: Palivizumab is suggested to be started between February/March and June/July for most Brazilian states, with the exception of Rio Grande do Sul, which, in addition to presenting the highest rates of hospitalizations for acute viral bronchiolitis per 10,000 live births, has the longest seasonal peak between May and September.

RESUMO Objetivo: Em razão do alto custo e do curto prazo da imunização passiva contra o vírus sincicial respiratório, principal vírus causador de bronquiolite viral aguda, a previsão das regiões e meses epidêmicos é extremamente importante. Objetiva-se identificar o mês de início do pico sazonal e as regiões e Estados brasileiros de maior incidência de hospitalizações mensais por bronquiolite viral aguda. Métodos: Com dados obtidos no Departamento de Informática do Sistema Único de Saúde do Brasil, foram calculadas as taxas mensais de hospitalizações por bronquiolite viral aguda a cada 10 mil nascidos vivos de crianças com idade inferior a 12 meses, em todos os Estados brasileiros e no Distrito Federal, no período entre 2000 e 2019. Modelos sazonais autorregressivos integrados e de médias móveis foram estimados para a previsão das taxas mensais de hospitalizações em 2020. Resultados: Verificou-se maior incidência de hospitalizações em crianças do sexo masculino, principalmente naquelas com idade inferior a seis meses. Em relação às regiões brasileiras, entre 2000 e 2019, a Região Sul apresentou a maior incidência de hospitalizações, seguida pelas Regiões Sudeste, Centro-Oeste, Norte e Nordeste, respectivamente. Quanto ao pico sazonal, o período entre março e julho de 2020 compreende as maiores taxas de hospitalizações previstas. Conclusões: Sugere-se o início da administração do Palivizumab entre fevereiro/março e junho/julho para a maioria dos Estados brasileiros, com exceção do Rio Grande do Sul, que, além de apresentar as maiores taxas de hospitalizações por bronquiolite viral aguda a cada 10.000 nascidos vivos, possui o pico sazonal de maior duração entre maio e setembro.

Post-acute COVID and long-COVID among adults and older adults in the State of Paraná, Brazil: protocol for an ambispective cohort study.

INTRODUCTION: Since 2020, the world has been going through a viral pandemic with a high morbidity and mortality rate along with the potential to evolve from an acute infection to post-acute and long-COVID, which is still in the process of elucidation. Diagnostic and prognostic research is essential to understand the complexity of factors and contexts involving the illness's process. This protocol introduces a study strategy to analyse predictors, sequelae, and repercussions of COVID-19 in adults and older adults with different disease severities in the State of Paraná, Brazil. METHODS AND ANALYSIS: A mixed-methods sequential explanatory design. The quantitative data will be conducted by an ambispective cohort study, which will explore the manifestations of COVID-19 for 18 months, with nearly 3000 participants with confirmed diagnoses of COVID-19 (reverse transcription-PCR test) between March and December of 2020, retrieved from national disease reporting databases, over 18 years old, living in a Brazilian State (Paraná) and who survived the viral infection after being discharged from a health service. Data collection will be conducted through telephone interviews, at two different occasions: the first will be a recall 12 months after the acute phase as a retrospective follow-up, and the second will be another prospective interview, with data of the following 6 months. For the qualitative step, Grounded Theory will be used; participants will be selected from the cohort population. The first sample group will be composed of people who were discharged from the intensive care unit, and other sample groups will be composed according to theoretical saturation. The qualitative data will follow the temporal design and classification of the disease provided for in the cohort. ETHICS AND DISSEMINATION: Ethics approval was granted by the State University of Maringá, under opinion number: 4 165 272 and CAAE: 34787020.0.0000.0104 on 21 July 2020, and Hospital do Trabalhador (Worker's Hospital), which is accountable for the Health Department of the State of Paraná, under opinion number: 4 214 589 and CAAE: 34787020.0.3001.5225 on 15 August 2020. The participants will verbally consent to the research, their consent will be recorded, and the informed consent form will be sent by mail or email. Outcomes will be widely disseminated through peer-reviewed manuscripts, conference presentations, media and reports to related authorities.

Time series of hospitalizations of adolescents due to mental and behavioral disorders / Serie temporal de las internaciones de adolescentes por trastornos mentales y comportamentales / Série temporal das internações de adolescentes por transtornos mentais e comportamentais

ABSTRACT Objective: to analyze the trend of hospitalizations of adolescents due to mental and behavioral disorders in Paraná, from 1998 to 2015. Method: ecological study of time series. Data were analyzed by means of segmented linear regression modeling for time series, estimated for each of the four health macro-regions. Results: the East macro-region showed a greater trend to increase hospitalizations from January 1998 to November 2003 (β1=0.006, p<0.001). In other macro-regions, there were similar trends with a sudden increase in February 2010, but with a further gradual decrease until December 2015. In the quadrennium 2012-2015, 38.06% of the hospitalizations lasted 29 or more days, and in the Northwest macro-region, hospitalizations lasted for up to seven days. The main cause of hospitalization was the use of alcohol and other drugs. Conclusion: there is a need to strengthen health actions to prevent drug use and improvements in the care network.

Bronchiolitis Hospitalization in Southern Brazil from 2002 to 2012: A Count Time-series Approach.

INTRODUCTION: Because the antibody neutralizing respiratory syncytial virus (anti-RSV) has a short period of immunization and high cost, the identification of regions and months of highest occurrence of bronchiolitis is very important. METHODS: An Autoregressive Conditional Poisson model was constructed for count data and compared to the standard time-series Poisson regression model. RESULTS: The metropolitan area of Paraná presented the highest average occurrence from May to July. CONCLUSIONS: The constructed model presented a better fit and allowed prediction of when and where the bronchiolitis hospitalizations are distributed.
