- Understanding Sabia virus infections (Brazilian mammarenavirus)(2022) NASTRI, Ana Catharina; DUARTE-NETO, Amaro Nunes; CASADIO, Luciana Vilas Boas; SOUZA, William Marciel de; CLARO, Ingra M.; MANULI, Erika R.; SELEGATTO, Gloria; SALOMA, Matias C.; FIALKOVITZ, Gabriel; TABORDA, Mariane; ALMEIDA, Bianca Leal de; MAGRI, Marcello C.; GUEDES, Ana Rubia; NETO, Laura Vieira Perdigao; SATAKI, Fatima Mitie; GUIMARAES, Thais; MENDES-CORREA, Maria Cassia; TOZETTO-MENDOZA, Tania R.; FUMAGALLI, Marcilio Jorge; HO, Yeh-Li; SILVA, Camila ALves Maia da; COLETTI, Thais M.; JESUS, Jacqueline Goes de; ROMANO, Camila M.; HILL, Sarah C.; PYBUS, Oliver; PINHO, Joao Renato Rebello; LEDESMA, Felipe Lourenco; CASAL, Yuri R.; KANAMURA, Cristina; ARAUJO, Leonardo Jose Tadeu de; FERREIRA, Camila Santos da Silva; GUERRA, Juliana Mariotti; FIGUEIREDO, Luiz Tadeu Moraes; DOLHNIKOFF, Marisa; FARIA, Nuno R.; SABINO, Ester C.; AVANCINI, Venacio; ALVES, Ferreira; LEVIN, Anna S.Background: Only two naturally occurring human Sabi ' a virus (SABV) infections have been reported, and those occurred over 20 years ago. Methods: We diagnosed two new cases of SABV infection using metagenomics in patients thought to have severe yellow fever and described new features of histopathological findings. Results: We characterized clinical manifestations, histopathology and analyzed possible nosocomial transmission. Patients presented with hepatitis, bleeding, neurological alterations and died. We traced twenty-nine hospital contacts and evaluated them clinically and by RT-PCR and neutralizing antibodies. Autopsies uncovered unique features on electron microscopy, such as hepatocyte ""pinewood knot"" lesions. Although previous reports with similar New-World arenavirus had nosocomial transmission, our data did not find any case in contact tracing. Conclusions: Although an apparent by rare, Brazilian mammarenavirus infection is an etiology for acute hemorrhagic fever syndrome. The two fatal cases had peculiar histopathological findings not previously described. The virological diagnosis was possible only by contemporary techniques such as metagenomic assays. We found no subsequent infections when we used serological and molecular tests to evaluate close contacts.
- Impact of COVID-19 on healthcare-associated infections: Antimicrobial consumption does not follow antimicrobial resistance(2023) FREIRE, Maristela Pinheiro; ASSIS, Denise Brandao de; TAVARES, Bruno de Melo; BRITO, Valquiria O. C.; MARINHO, Igor; LAPCHIK, Milton; GUEDES, Ana Rubia; MADALOSSO, Geraldine; OLIVEIRA, Maura Salaroli; LIMA, Antonio Carlos Pedroso de; LEVIN, Anna S.Background: This study aimed to analyze the Healthcare-Associated Infections (HAI) rates and antimicrobial consumption in Intensive Care Units (ICU) in Sao Paulo city during the COVID-19 pandemic and compare them with the pre-pandemic period. Methods: This cohort included all hospitals that reported HAI rates (Central-Line-Associated Bloodstream Infection CLABSI and Ventilator-Associated Pneumonia - VAP), the proportion of microorganisms that caused CLABSI, the proportion of resistant microorganisms, and antimicrobial consumption from January 2017 - December 2020. Hospitals were stratified by the number of beds, Central Venous Catheter (CVC) utilization rate, Mechanical-Ventilation (MV) utilization rate, and type of funding. Statistical analyses were based on time-series plots and regression models. Results: 220 ICUs were included. The authors observed an abrupt increase in CLABSI rates after the pandemic onset. High CLABSI rates during the pandemic were associated with hospital size, funding (public and non-profit private), and low CVC use (<= 50%). An increase in VAP rates was associated with public hospitals, and high MV use (> 35%). The susceptibility profile of microorganisms did not differ from that of the pre-pandemic period. polymyxin, glycopeptides, and antifungal use increased, especially in COVID-19 ICUs. Conclusions: HAI increased during COVID-19. The microorganisms' susceptibility profile did not change with the pandemic, but the authors observed a disproportionate increase in large-spectrum antimicrobial drug use.
- Clinical features of COVID-19 by SARS-CoV-2 Gamma variant: A prospective cohort study of vaccinated and unvaccinated healthcare workers(2022) LUNA-MUSCHI, Alessandra; BORGES, Igor C.; FARIA, Elizabeth de; BARBOZA, Antonio S.; MAIA, Fernando L.; LEME, Mariana D.; GUEDES, Ana Rubia; MENDES-CORREA, Maria Cassia; KALLAS, Esper G.; SEGURADO, Aluisio C.; DUARTE, Alberto J.

- Increased Risk for Carbapenem-Resistant Enterobacteriaceae Colonization in Intensive Care Units after Hospitalization in Emergency Department(2020) SALOMAO, Matias Chiarastelli; FREIRE, Maristela Pinheiro; BOSZCZOWSKI, Icaro; RAYMUNDO, Sueli F.; GUEDES, Ana Rubia; LEVIN, Anna S.Carbapenem-resistant Enterobacteriaceae (CRE) colonization is common in hospital patients admitted to intensive care units (ICU) from the emergency department. We evaluated the effect of previous hospitalization in the emergency department on CRE colonization at ICU admission. Our case-control study included 103 cases and 201 controls; cases were patients colonized by CRE at admission to ICU and controls were patients admitted to ICU and not colonized. Risk factors were emergency department stay, use of carbapenem. Simplified Acute Physiology Score, upper digestive endoscopy, and transfer from another hospital. We found that ED stay before ICU admission was associated with CRE colonization at admission to the ICU. Our findings indicate that addressing infection control problems in EDs will help to control carbapenem resistance in ICUs.
- Statewide evaluation of infection control measures for preventing coronavirus disease 2019 in hemodia-lysis facilities(2021) GUEDES, Ana Rubia; TAVARES, Bruno de Melo; ASSIS, Denise Brandao de; FREIRE, Maristela Pinheiro; MADALOSSO, Geraldine; LEVIN, Anna S.; PERDIGAO NETO, Lauro Vieira; OLIVEIRA, Maura Salaroli deOBJECTIVE: This study aimed to evaluate the occurrence of coronavirus disease 2019 (COVID-19) in hemodialysis facilities and the occurrence of and risk factors for clustering of COVID-19 cases. METHODS: We conducted a cross-sectional online survey between March and July 2020, in all dialysis facilities in Sao Paulo state, using Google Forms. The online questionnaire contained questions addressing specific components of infection prevention and control practices and the number of cases during the COVID-19 pandemic. RESULTS: A total of 1,093 (5%) COVID-19 cases were reported among 20,984 patients; approximately 56% of the facilities had X1 cluster. Most facilities implemented various measures (such as allocation of dedicated COVID-19 areas/shifts, symptom screening, environmental disinfection, and maintenance of adequate ventilation) to prevent the transmission of severe acute respiratory syndrome coronavirus 2. Clustering of COVID-19 cases was suspected in only 7% of dialysis facilities. The only variable associated with this event was the performance of aerosol-generating procedures (odds ratio: 4.74; 95% confidence interval: 1.75-12.86). CONCLUSION: Attention should be paid to avoiding the performance of aerosol-generating procedures in dialysis facilities and monitoring the clustering of cases.
- Decontamination and re-use of surgical masks and respirators during the COVID-19 pandemic(2021) CORTES, Marina Farrel; ESPINOZA, Evelyn Patricia Sanchez; NOGUERA, Saidy Liceth Vasconez; SILVA, Aline Alves; MEDEIROS, Marion Elke Sielfeld Araya de; BOAS, Lucy Santos Villas; FERREIRA, Noely Evangelista; TOZETTO-MENDOZA, Tania Regina; MORAIS, Fernando Goncalves; QUEIROZ, Rayana Santiago de; PROENCA, Adriana Coracini Tonacio de; GUIMARAES, Thais; GUEDES, Ana Rubia; LETAIF, Leila Suemi Harima; MONTAL, Amanda Cardoso; MENDES-CORREA, Maria Cassia; JOHN, Vanderley M.; LEVIN, Anna S.; COSTA, Silvia FigueiredoObjectives: The coronavirus disease 2019 pandemic increased global demand for personal protective equipment (PPE) and resulted in shortages. The study evaluated the re-use of surgical masks and respirators by analysing their performance and safety before and after reprocessing using the following methods: oven, thermal drying, autoclave, and hydrogen peroxide plasma vapour. Methods: In total, 45 surgical masks and 69 respirators were decontaminated. Visual integrity, air permeability, burst resistance, pressure differential and particulate filtration efficiency of new and decontaminated surgical masks and respirators were evaluated. In addition, 14 used respirators were analysed after work shifts before and after decontamination using reverse transcription polymerase chain reaction (RT-PCR) and viral culturing. Finally, reprocessed respirators were evaluated by users in terms of functionality and comfort. Results: Oven decontamination (75 degrees C for 45 min) was found to be the simplest decontamination method. Physical and filtration assays indicated that all reprocessing methods were safe after one cycle. Oven decontamination maintained the characteristics of surgical masks and respirators for at least five reprocessing cycles. Viral RNA was detected by RT-PCR in two of the 14 used respirators. Four respirators submitted to viral culture were PCR-negative and culture-negative. Reprocessed respirators used in work shifts were evaluated positively by users, even after three decontamination cycles. Conclusion: Oven decontamination is a safe method for reprocessing surgical masks and respirators for at least five cycles, and is feasible in the hospital setting.
