Urinary tract infections are prone to overdiagnosis, and reflex urine culture protocols offer a valuable opportunity for diagnostic stewardship in this arena. However, there is no recommended standard testing approach. Cancer patients often excluded from protocols, especially if severely immunosuppressed or neutropenic. The aim of study was evaluate the performance characteristics screening studies, including dipstick urinalysis nitrite leukocyte esterase microscopy white blood cell count,...

AZD7442 (tixagevimab-cilgavimab) is a combination of two human monoclonal antibodies for pre-exposure prophylaxis severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection among high-risk patients who do not mount reliable vaccine response. Foremost these are hematologic malignancy with limited clinical trial or realworld experience to assess the effectiveness this treatment since emergence Omicron and its subvariants. We performed retrospective study 892 received at Memorial...

Abstract Background: Universal masking within healthcare settings was adopted to combat the spread of coronavirus disease 2019 (COVID-19). In addition mitigating risk for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, it also had an added benefit preventing nosocomial transmission other respiratory viral diseases. Objective: This study examines impact intervention on infections (RVI) in vulnerable sub-populations people with cancer at a tertiary care hospital....

Abstract Background Sotrovimab is an anti-spike neutralization monoclonal antibody developed to reduce the risk of coronavirus disease 2019 (COVID-19) progression and advancement hospitalization in high-risk patients. Currently, there limited research describing association sotrovimab treatment patients with hematologic malignancy predictive factors hospitalization. Methods We performed observational study 156 consecutive cancer who received at Memorial Sloan Kettering Cancer Center New York...

Abstract Background: SARS-CoV-2 asymptomatic surveillance testing (AST) is a common strategy to minimize the risk of nosocomial infection in patients and healthcare personnel. In contrast admission screening, post-admission AST was less widely adopted. Objective: This study describes diagnostic yield serial SARS-COV-2 hospitalized at large cancer center with mostly double-occupancy rooms. Design: Retrospective cohort design. Post-admission tests were examined over 18 month period. Positive...

Abstract Background The American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE) recommends that hospital operating rooms (OR) are controlled for temperature humidity with established ranges but does allow exceedances surgeons surgical procedures. There is currently no clear consensus or thresholds out-of-range in relation to risk site infections (SSI). A study was performed at Memorial Sloan Kettering Cancer Center (MSKCC) further examine if deviations pose a...
