Increased body mass index is a risk factor for acute promyelocytic leukemia.

Introduction: Obesity has become increasingly prevalent worldwide and is a risk factor for many malignancies. We studied the correlation between body mass index (BMI) and the incidence of acute promyelocytic leukemia (APL), non-APL acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and control hospitalized patients without leukemia in the same community. Methods: Multi-center, retrospective analysis of 71,196 patients: APL (n=200), AML (n=437), ALL (n=103), non-leukemia hospitalized (n=70,456) admitted to University of Maryland and Johns Hopkins Cancer Centers, and University of Maryland Medical Center. Results: Patients with APL had a significantly higher unadjusted mean and median BMI (32.5 kg/m2 and 30.3 kg/m2) than those with AML (28.3 kg/m2 and 27.1 kg/m2), ALL (29.3 kg/m2 and 27.7 kg/m2), and others (29.3 kg/m2 and 27.7 kg/m2) (p<0.001). Log-transformed BMI multivariable models demonstrated that APL patients had a significantly higher adjusted mean BMI by 3.7 kg/m2 (p<0.001) or approximately 10% (p<0.01) compared to the other groups, when controlled for sex, race, and age. Conclusions: This study confirms that when controlled for sex, age, and race there is an independent association of higher BMI among patients with APL compared to patients with ALL, AML, and hospitalized individuals without leukemia in the same community.

National Early Warning Score Is Modestly Predictive of Care Escalation after Emergency Department-to-Floor Admission.

BACKGROUND: Decompensation on the medical floor is associated with increased in-hospital mortality. OBJECTIVE: Our aim was to determine the accuracy of the National Early Warning Score (NEWS) in predicting early, unplanned escalation of care in patients admitted to the hospital from the emergency department (ED) compared to the Shock Index (SI) and the quick Sepsis-Related Organ Failure Assessment (qSOFA) score. METHODS: We conducted a retrospective cohort study of patients admitted directly from the ED to monitored or unmonitored beds (November 9, 2015 to April 30, 2018) in 3 hospitals. Interhospital transfers were excluded. Patient data, vital status, and bed assignment were extracted from the electronic medical record. Scores were calculated using the last set of vital signs prior to leaving the ED. Primary endpoint was in-hospital death or placement in an intermediate or intensive care unit within 24 h of admission from the ED. Scores were compared using the area under the receiver operating curve (AUROC). RESULTS: Of 46,018 ED admissions during the study window, 39,491 (85.8%) had complete data, of which 3.7% underwent escalation in level of care within 24 h of admission. NEWS outperformed (AUROC 0.69; 95% confidence interval [CI] 0.68-0.69) qSOFA (AUROC 0.63; 95% CI 0.62-0.63; p < 0.001) and SI (AUROC 0.60; 95% CI 0.60-0.61; p < 0.001) at predicting unplanned escalations or death at 24 h. CONCLUSIONS: This multicenter study found NEWS was superior to the qSOFA score and SI in predicting early, unplanned escalation of care for ED patients admitted to a general medical-surgical floor.

Life-threatening hemoptysis following mitral valvuloplasty for rheumatic mitral stenosis.

BACKGROUND: Massive hemoptysis is a rare complication of rheumatic mitral valve stenosis. Its recurrence following successful initial treatment of the stenosis has not, to our knowledge, been described. CASE REPORT: We describe a 58-year-old African American woman with a history of balloon valvuloplasty for the treatment of severe rheumatic mitral valve stenosis who presented to our institution with massive life-threatening hemoptysis due to recurrent mitral valve stenosis. Repeat balloon valvuloplasty was complicated postoperatively by severe mitral regurgitation and the patient expired from refractory cardiopulmonary collapse not amenable to further intervention. CONCLUSION: Life-threatening hemoptysis is a medical emergency requiring rapid source identification and treatment of the underlying etiology. A high degree of suspicion should be maintained for recurrence of mitral valve stenosis in patients presenting with life-threatening hemoptysis and risk factors of rheumatic heart disease, regardless of previous surgical management or unilateral chest x-ray signs.
