    Terrorism using radiological dirty bombs or improvised nuclear devices is recognized as a major threat to both public health and national security. In the event of a radiological or nuclear disaster, rapid and accurate biodosimetry of thousands of potentially affected individuals will be essential for effective medical management to occur. Currently, health care providers lack an accurate, high-throughput biodosimetric assay which is suitable for the triage of large numbers of radiation injury victims. Here, we describe the development of a biodosimetric assay based on the analysis of irradiated mice, ex vivo-irradiated human peripheral blood (PB) and humans treated with total body irradiation (TBI). Interestingly, a gene expression profile developed via analysis of murine PB radiation response alone was inaccurate in predicting human radiation injury. In contrast, generation of a gene expression profile which incorporated data from ex vivo irradiated human PB and human TBI patients yielded an 18-gene radiation classifier which was highly accurate at predicting human radiation status and discriminating medically relevant radiation dose levels in human samples. Although the patient population was relatively small, the accuracy of this classifier in discriminating radiation dose levels in human TBI patients was not substantially confounded by gender, diagnosis or prior exposure to chemotherapy. We have further incorporated genes from this human radiation signature into a rapid and high-throughput chemical ligation-dependent probe amplification assay (CLPA) which was able to discriminate radiation dose levels in a pilot study of ex vivo irradiated human blood and samples from human TBI patients. Our results illustrate the potential for translation of a human genetic signature for the diagnosis of human radiation exposure and suggest the basis for further testing of CLPA as a candidate biodosimetric assay.

    Febrile Neutropenia: Improving Care Through an Oncology Acute Care Clinic
    (Clinical Journal of Oncology Nursing, 2023-02-01) Frith, Jennifer; Allen, Deborah Hutch; Minor, Kerry; Reynolds, Staci S
    BACKGROUND: Patients with cancer are at risk for oncologic emergencies, including febrile neutropenia (FN). Timely treatment of FN can prevent complications. Providing this care in the outpatient setting has been shown to be safe and effective. OBJECTIVES: This project implemented and evaluated a new process using an outpatient acute care clinic (ACC) to manage FN in patients with hematologic cancer. The aims were to reduce the time from fever identification to antibiotic administration, decrease emergency department (ED) visit rates, and evaluate patient satisfaction. METHODS: Using a pre-/postimplementation design, an interprofessional team was educated about a new process of caring for patients with hematologic cancer and FN at an outpatient ACC using a comprehensive algorithm. FINDINGS: 31 patients participated in the project (15 pre-and 16 postimplementation). Time to antibiotic administration decreased from 144.88 minutes to 63.69 minutes. Participant visits to the ED decreased by 2.33 times per month on average. Overall, patients were satisfied with the ACC. These findings support using a dedicated outpatient ACC for patients with FN receiving hematology care.
