The emergence of a new class of agents (B-cell-depleting therapies) has opened a new era in the therapeutic approach to systemic lupus erythematosus, with belimumab being the first drug licensed for use in systemic lupus erythematosus in more than 50 years. Four agents deserve specific mention: rituximab, ocrelizumab, epratuzumab, and belimumab. ⋯ B-cell-depleting agents should not be used in patients with mild disease and should be tailored according to individual patient characteristics, including ethnicity, organ involvement, and the immunological profile. Forthcoming studies of B-cell-directed strategies, particularly data from investigations of off-label rituximab use and postmarketing studies of belimumab, will provide new insights into the utility of these treatments in the routine management of patients with systemic lupus erythematosus.

Boarding admitted patients in the emergency department due to high hospital occupancy is a worldwide problem. However, whether or not emergency department-boarded patients managed by emergency department providers subjects them to increased serious complications needs further clarification. ⋯ High hospital occupancy was associated with an increased incidence of serious complications within 24 hours for patients admitted but still boarded in the emergency department and managed by emergency department providers.

Patients with sleep apnea have been reported to be associated with increased prevalence of deep vein thrombosis (DVT) in some papers, which were criticized for either a small sample size or lack of a prospective control. Our study strived to explore the relationship of sleep apnea and the subsequent development of DVT using a nationwide, population-based database. ⋯ Sleep apnea may be an independent risk factor for DVT.

Variation in emergency department head computed tomography (CT) use in patients with atraumatic headaches between hospitals is being measured nationwide. However, the magnitude of interphysician variation within a hospital is currently unknown. We hypothesized that there was significant variation in the rates of physician head CT use, both overall and for patients diagnosed with atraumatic headaches. ⋯ Emergency physicians vary significantly in their use of head CT both overall and in patients with atraumatic headaches. Further studies are needed to identify strategies to reduce interphysician variation in head CT use.

Point-of-care devices for measurement of the international normalized ratio (INR) are commonly used to monitor therapy and maintain therapeutic levels of anticoagulation in patients treated with vitamin K antagonists. Dabigatran, a new oral, reversible direct thrombin inhibitor approved for stroke prevention in patients with atrial fibrillation does not require routine coagulation monitoring. However, case reports have identified falsely elevated point-of-care INR levels in patients treated with dabigatran using one of these devices (Hemochron). This in vitro study was designed to verify this issue. ⋯ INR levels in patients taking dabigatran are substantially higher using a Hemochron Jr. point-of-care device compared with laboratory values. We discourage the use of these devices specifically, as well as the use of the INR in general, for measuring the anticoagulant effect of dabigatran.
