Some studies have shown that secondary infections during the COVID-19 pandemic may have contributed to the high mortality. Our objective was to identify the frequency, types and etiology of bacterial infections in patients with COVID-19 admitted to an intensive care unit (ICU) and to evaluate the results of ICU stay, duration of mechanical ventilation (MV) and inhospital mortality. It was a single-center study with a retrospective cohort of patients admitted consecutively to the ICU for more than 48 h between March and May 2020. Comparisons of groups with and without ICU-acquired infection were performed. A total of 191 patients with laboratory-confirmed COVID-19 were included and 57 patients had 97 secondary infectious events. The most frequent agents were Acinetobacter baumannii (28.9%), Pseudomonas aeruginosa (22.7%) and Klebsiella pneumoniae (14.4%); multi-drug resistance was present in 96% of A. baumannii and in 57% of K. pneumoniae. The most prevalent infection was ventilator-associated pneumonia in 57.9% of patients with bacterial infections, or 17.3% of all COVID-19 patients admitted to the ICU, followed by tracheobronchitis (26.3%). Patients with secondary infections had a longer ICU stay (40.0 vs. 17 days; p < 0.001), as well as a longer duration of MV (24.0 vs 9.0 days; p= 0.003). There were 68 (35.6%) deaths overall, of which 27 (39.7%) patients had bacterial infections. Among the 123 survivors, 30 (24.4%) had a secondary infections (OR 2.041; 95% CI 1.080 -3.859). A high incidence of secondary infections, mainly caused by gram-negative bacteria has been observed. Secondary infections were associated with longer ICU stay, MV use and higher mortality.

Resumo Fundamentos A incidência de injúria miocárdica (IM) em pacientes com COVID-19 no Brasil é pouco conhecida e o impacto prognóstico da IM, mal elucidado. Objetivos Descrever a incidência de IM em pacientes com COVID-19 em unidade de terapia intensiva (UTI) e identificar variáveis associadas à sua ocorrência. O objetivo secundário foi avaliar a troponina I ultrassensível (US) como preditor de mortalidade intra-hospitalar. Métodos Estudo observacional, retrospectivo, entre março e abril de 2020, com casos confirmados de COVID-19 internados em UTI. Variáveis numéricas foram comparadas com teste t de Student ou U de Mann-Whitney, sendo o teste X2 empregado para as categóricas. Realizou-se análise multivariada com as variáveis associadas à IM e p<0,2 objetivando determinar preditores de IM. Curva ROC foi empregada para determinar o valor da troponina capaz de predizer maior mortalidade intra-hospitalar. Funções de sobrevida foram estimadas pelo método de Kaplan-Meier a partir do ponto de corte apontado pela curva ROC. Resultados Este estudo avaliou 61 pacientes (63,9% do sexo masculino, média de idade de 66,1±15,5 anos). A IM esteve presente em 36% dos casos. Hipertensão arterial sistêmica (HAS) [RC 1,198; IC95%: 2,246-37,665] e índice de massa corporal (IMC) [RC 1,143; IC95%: 1,013-1,289] foram preditores independentes de risco. Troponina I US >48,3 ng/ml, valor determinado pela curva ROC, prediz maior mortalidade intra-hospitalar [AUC 0,786; p<0,05]. A sobrevida no grupo com troponina I US >48,3 ng/ml foi inferior à do grupo com valores ≤48,3 ng/dl [20,3 x 43,5 dias, respectivamente; p<0,05]. Conclusão Observou-se alta incidência de IM na COVID-19 grave com impacto em maior mortalidade intra-hospitalar. HAS e IMC foram preditores independentes de risco de sua ocorrência.

Objectiveto translate the Hip Outcome Score clinical evaluation questionnaire into Portuguese and culturally adapt it for Brazil.Methodsthe Hip Outcome Score questionnaire was translated into Portuguese following the methodology consisting of the steps of translation, back-translation, pretesting and final translation.Resultsthe pretesting was applied to 30 patients with hip pain without arthrosis. In the domain relating to activities of daily living, there were no difficulties in comprehending the translated questionnaire. In presenting the final translation of the questionnaire, all the questions were understood by more than 85% of the individuals.Conclusionthe Hip Outcome Score questionnaire was translated and adapted to the Portuguese language and can be used in clinical evaluation on the hip. Additional studies are underway with the objective of evaluating the reproducibility and validity of the Brazilian translation.

CONTEXT AND OBJECTIVE: The Nonarthritic Hip Score (NAHS) is a clinical evaluation questionnaire that was developed in the English language to evaluate hip function in young and physically active patients.
