Introduction: Antimicrobial resistance has worsened since the onset of COVID-19. Methods: This study involved patients admitted to the adult intensive care unit (ICU) of a tertiary hospital. Pre-and post-COVID-19 data were analyzed. The healthcare-related infections (HCRIs) reported between January 2018 and January 2020 and during the pandemic between February and July 2020 were compared. Results: Antimicrobial resistance increased during the pandemic, especially for Klebsiella pneumoniae isolates, with a rate increase from 5% to 50% for Polymyxin B. Conclusions: The susceptibilities of the main pathogens associated with HCRIs in the ICU changed and should be considered in managing severe COVID-19.

ABSTRACTDespite improvements in care and rehabilitation of burned patients, infections still remain the main complication and death cause. Catheter-related infections are among the four most common infections and are associated with skin damage and insertion site colonization. There are few studies evaluating this kind of infection worldwide in this special group of patients. Padre Albino Hospital Burn Care Unit (PAHBCU) is the only reference center in the Northwestern São Paulo for treatment of burned patients. This paper presents the results of a retrospective study aiming at describing the epidemiological and clinical features of catheter-related infections at PAHBCU.
OBJETIVO: Estudar os efeitos de múltiplas esterilizações em formaldeido em baixa temperatura, na estrutura molecular (físico-químico) e no desenvolvimento de microorganismos na tela de polipropileno, utilizada na correção cirúrgica das diferentes hérnias da parede abdominal. MÉTODO: Utilizou-se tela de polipropileno plana padrão (Ethicon), de 15cm x 15cm, a qual foi recortada em fragmentos iguais de 2cm x 1cm, após múltiplas esterilizações. Foram denominadas amostras A (controle), A1 (uma esterilização) e A3 (três esterilizações); e B (controle), B1 (uma esterilização), B2 (duas esterilizações), B3 (três esterilizações), B4 (quatro esterilizações) e B5 (cinco esterilizações). As amostras A foram submetidas à análise por Espectroscopia no Infravermelho (FTIR) e Microscopia Eletrônica por Varredura (MEV) e as amostras B foram semeadas em meios de "Brain Heart Infusion" (BHI), Ágar Sabouraud Dextrosado e Ágar Chocolate (hemácias de carneiro a 5%). RESULTADOS: A análise comparativa das amostras A, A1 e A3 revela suficientes evidências experimentais de que sejam idênticas, do ponto de vista da composição, mantendo, inclusive, os mesmos padrões de porosidade. Nas amostras B1, B2, B3, B4 e B5 não houve desenvolvimento de microorganismos nos fragmentos submetidos até cinco esterilizações. CONCLUSÕES: A tela de polipropileno não sofre alterações na sua estrutura molecular, podendo ser submetida até cinco esterilizações, sem que ocorra o desenvolvimento de microorganismos nas amostras.
