Comprehensive infection control measures prevent hospital-acquired severe acute respiratory syndrome coronavirus 2 infection: A single-center prospective cohort study and seroprevalence survey

This study aimed to assess the risk of SARS-CoV-2 infection among healthcare workers (HCWs) and the effectiveness of infection control measures. Methods This study had a cross-sectional component and a prospective cohort component. The cross-sectional component comprised an anti-SARS-CoV-2 antibody survey among HCWs at a medical center in Saitama City, Japan. In the prospective cohort component, HCWs at the same medical center were tested for anti-SARS-CoV-2 antibodies monthly over a 3-month period (May to July 2020) to assess the effectiveness of infection prevention measures, including personal protective equipment use. All participants in the cohort study also participated in the antibody survey. The primary outcome was anti-SARS...

Native mitral valve infective endocarditis caused by Staphylococcus warneri: A case-based review

We presented a 72-year-old woman with native mitral valve S. warneri IE associated with spondylitis and cerebellar infarction. Physicians should be wary of IE and disseminated lesions when blood cultures reveal S. warneri, especially in elderlies with valvular heart disease.

517. Association of the predictive risk scores of CALL points and COVID-GRAM with IL-6, duration of oxygen therapy, D-dimer among patients with COVID-19

Critically ill patients with COVID-19 can develop acute respiratory distress syndrome (ARDS) and thrombosis. Angiotensin-converting enzyme 2 is a functional receptor for severe acute respiratory syndrome coronavirus 2 to gain entry in cells. This receptor is widely expressed in some hematopoietic cells, including monocytes and macrophages. Infection of these cells results in secretion of interleukin (IL)-6 and other inflammatory cytokines. IL-6 and other inflammatory cytokines can cause ARDS and thrombosis. Elevated IL-6 levels are expected to cause more severe cytokine release syndrome. In this study we investigated the association of the predictive risk scores with the IL-6 level, duration of oxygen therapy (DOT), and D-dimer level. Methods We enrolled 20 consecutive patients diagnosed with COVID-19 from April 3, 2020, to April 30, 2020, and determined the predictive risk scores of CALL point...
