Acute GVHD, BK virus hemorrhagic cystitis and age are risk factors for transplant-associated thrombotic microangiopathy in adults.

Hematopoietic cell transplantation-associated thrombotic microangiopathy (TMA) is a complication associated with higher nonrelapse mortality (NRM) in patients who undergo allogeneic transplant (HCT). Current classification criteria are not generally agreed on or validated, and the presence of confounding factors after transplant contribute to underdiagnosis or delayed diagnosis of TMA. We studied risk factors, incidence, and biomarkers of TMA in 119 adult allogeneic HCT recipients. Twenty-seven patients developed a clinically actionable phenotype of TMA (CA-TMA) and the incidence of CA-TMA was 22% by day 180. Among the 27 patients who developed CA-TMA, 10 developed it before the onset of acute graft-versus-host disease (aGVHD), and 17 patients developed it after the onset of aGVHD. We report for the first time that age >50 years, BK hemorrhagic cystitis, and other viral infections (CMV, HHV-6, or adenovirus) are risk factors for adult CA-TMA. Even after adjustment for aGVHD, CA-TMA was independently associated with significantly higher NRM. These data illustrate relationships between CA-TMA and aGVHD, describe new risk factors for CA-TMA and emphasizes the need to develop validated set of criteria for timely diagnosis.

Burnout and Well-Being: Evaluating Perceptions in Bone Marrow Transplantation Nurses Using a Mindfulness Application.

BACKGROUND: Oncology nurses are at increased risk for developing burnout. Although various interventions have been researched, mindfulness has been proven to be beneficial in mitigating burnout while improving well-being. OBJECTIVES: The aim was to evaluate whether the use of a mindfulness mobile application (app), Headspace®, increases perceptions of well-being and decreases perceptions of burnout among inpatient bone marrow transplantation (BMT) staff nurses and nurse practitioners (NPs). METHODS: This evidence-based practice quality improvement initiative introduced the Headspace app to BMT nurses and evaluated its impact on burnout and well-being at baseline and every 30 days for 90 days. FINDINGS: There were significant improvements in burnout and well-being in staff nurses and NPs from baseline to each time point. Sleep hygiene meditations were the most widely used programs within the Headspace app for both nursing groups.
