Venous thromboembolism contributes significantly to morbidity and mortality in cancer patients. Because cancer patients frequently have contraindications to anticoagulation, inferior vena cava filters are commonly placed. The use, safety, and retrieval of retrievable inferior vena cava filters in cancer patients have not been well studied. ⋯ In a modern cohort of patients undergoing retrievable inferior vena cava filter placement, active diagnosis of cancer is not associated with a significant increase in filter-related complications, but is associated with a reduced rate of filter retrieval.

Often, the controversial diagnosis of chronic Lyme disease is given to patients with prolonged, medically unexplained physical symptoms. Many such patients also are treated for chronic coinfections with Babesia, Anaplasma, or Bartonella in the absence of typical presentations, objective clinical findings, or laboratory confirmation of active infection. We have undertaken a systematic review of the literature to evaluate several aspects of this practice. ⋯ The medical literature does not support the diagnosis of chronic, atypical tick-borne coinfections in patients with chronic, nonspecific illnesses.

Dabigatran, rivaroxaban, and apixaban have been approved for use in patients with atrial fibrillation based upon randomized trials demonstrating their comparable or superior efficacy and safety relative to warfarin. Little is known about their adoption into clinical practice, whether utilization is consistent with the controlled trials on which their approval was based, and how their use has affected health spending for patients and insurers. ⋯ This study demonstrates rapid adoption of novel anticoagulants into clinical practice, particularly among patients with lower CHADS2 and HAS-BLED scores, and high health care cost consequences. These findings provide important directions for future comparative and cost-effectiveness research.

Clinical practice guidelines recommend 40-60 mg of prednisone equivalent for 10-14 days for patients with acute exacerbations of chronic obstructive pulmonary disease (COPD). However, the amount of corticosteroid prescribed varies widely in clinical practice. Using the electronic health record, we implemented an evidence-based order set to standardize treatment of patients hospitalized with acute exacerbations of COPD. ⋯ Evidence-based electronic ordersets improve compliance with clinical practice guidelines and reduce the total dose of corticosteroid administered in patients hospitalized with acute exacerbations of COPD.

Osteoporosis is the prevalent manifestation of bone involvement in patients with systemic mastocytosis. Mastocytosis-related osteoporosis is characterized by both absolute and relative prevalence of osteoclastic activity, consistent with the positive results reported in small series of patients with antiresorptive drugs, such as bisphosphonates. The aim of this study is to investigate the efficacy of zoledronic acid in patients with mastocytosis-related osteoporosis. ⋯ A single 5 mg zoledronic acid intravenous infusion in patients with osteoporosis secondary to indolent systemic mastocytosis is associated with significant increases in spine and hip bone mineral density and decreases of bone turnover markers over at least 1 year. Yearly zoledronic acid might represent a therapeutic option for indolent systemic mastocytosis-associated osteoporosis.
