ABSTRACT
ABSTRACT Background: COVID-19 has been associated with persistent symptoms and functional changes, especially in those surviving severe disease. Methods: We conducted a prospective multicenter study in patients with severe COVID-19 to determine respiratory sequelae. Patients were stratified into two groups: ward admission (WA) and intensive care unit (ICU) admission. In each follow-up visit, the patients where inquired about cough and dyspnea, and performed spirometry, lung volumes, carbon monoxide diffusion capacity (DLCO), 6-minute walk test (6MWT), and respiratory muscle strength (MIP and MEP). Results of pulmonary function tests at 45 days and 6 months after hospital admission were compared using paired analysis. Results: 211 patients were included, 112 in WA and 99 in ICU. Dyspnea persisted in 64.7% in the WA and 66.7% in the ICU group after 6 months. Lung function measures showed significant improvement between 45 days and 6 months, both in WA and ICU groups in VC, FVC, FEV1, total lung capacity, and 6MW distance measures. The improvement in the proportions of the altered functional parameters was significant in the ICU group for VC (44.2% 45 d; 20.8% 6 m; p = 0,014), FVC (47.6% 45 d; 28% 6 m; p = 0,003), FEV1 (45.1% 45 d; 28% 6 m; p = 0,044), DLCO (33.8% 45 d; 7.7% 6 m; p < 0,0001). Conclusion: Six months follow-up of patients with the severe forms of COVID-19 showed significant improvement in the lung function measures compared to 45 days post hospital discharge. The difference was more evident in those requiring ICU admission.
ABSTRACT
Objetivo: analisar os fatores sociodemográficos relacionados ao não uso do preservativo nas relações sexuais e a prevalência de infecções sexualmente transmissíveis (IST) em comunidades rurais de Ouro Preto, Minas Gerais, Brasil, entre 2014 e 2016. Métodos: foram coletados dados de entrevista individual e realizados testes rápidos; as associações foram testadas pelo modelo de regressão de Poisson, com intervalo de confiança de 95% (IC95%). Resultados: foram detectados 3,8 casos/10 mil habitantes de hepatite B e sífilis, e 1,3/10 mil hab. de hepatite C; não foram detectados casos de HIV; na análise multivariada, foram encontradas maiores prevalências de não uso de preservativos entre indivíduos casados/em união estável/viúvos (RP=1,20 - IC95% 1,06;1,36). Conclusão: o grupo com maior prevalência de não uso de preservativo é o de pessoas com relacionamento fixo; novos casos de sífilis e de hepatites virais foram detectados pelo teste rápido, aplicado no inquérito.

Resultados: se detectaron 3,8 casos/10 mil habitantes de hepatitis B y sífilis, y 1,3/10 mil habitantes de hepatitis C; no se detectaron casos de VIH; el análisis multivariado mostró mayor prevalencia de no uso del preservativo para personas casadas /en unión estable/viudos (RP=1,20 - IC95% 1,06;1,36). Conclusión: se detectaron nuevos casos de sífilis y hepatitis virales por las pruebas rápidas en esta investigación; el grupo de mayor riesgo de no usar preservativo fue de personas casadas/con relación fija.
Objective: to investigate socio-demographic factors associated with non-use of condoms, and to describe the prevalence of sexually transmitted infections (STI) in rural communities of Ouro Preto, Minas Gerais, Brazil, 2014 to 2016. Methods: data were gathered from individual interviews and rapid tests were performed; associations were tested using Poisson regression, with a 95% confidence interval (95%CI). Results: we detected 3.8 cases/10,000 inhabitants for hepatitis B and syphilis, and 1.3 cases/10,000 inhabitants for hepatitis C; no HIV cases were detected; in the multivariate analysis we found higher prevalence rates of condom non-use among the group of individuals who were married, had common law partners or were widowed (PR=1.20 - 95%CI 1.06;1.36). Conclusion: individuals in a stable relationship formed the group with the highest prevalence rate of condom non-use; new syphilis and viral hepatitis cases were detected using rapid tests during the survey.
