Femoral venous access for catheter introduction represents the cornerstone of electrophysiology (EP) procedures. Limited data are available regarding postprocedure VTE. The aim of this systematic review is to determine the incidence of DVT and pulmonary embolism (PE) associated with femoral vein catheterization during EP procedures. ⋯ A lower incidence of symptomatic DVT and PE was observed after AF ablations as opposed to non-AF ablations, likely due to the use of routine periprocedural anticoagulation. Asymptomatic DVTs appear to be common, although their significance is unclear. Future studies are required to weigh the risk of hematoma against the risk of VTE associated with the use of prophylactic anticoagulation after non-AF ablation procedures.

Randomized Controlled Trial Comparative Study
Rapid vs Maintenance Vitamin D Supplementation in Deficient Asthmatic Children to Prevent Exacerbations.
Whether vitamin D reduces clinically important exacerbations of childhood asthma remains uncertain. We compared rapid to maintenance vitamin D repletion analyzed by baseline vitamin D level. ⋯ Rapid compared to maintenance vitamin D supplementation for children with the lowest levels resulted in short- but not long-term reduction in asthma exacerbations.

There is no published systematic review on the etiologies of chronic cough or the relationship between OSA and chronic cough in children aged ≤ 14 years. We thus undertook a systematic review based on key questions (KQs) using the Population, Intervention, Comparison, Outcome format. The KQs follow: Among children with chronic (> 4 weeks) cough (KQ 1) are the common etiologies different from those in adults? (KQ 2) Are the common etiologies age or setting dependent, or both? (KQ 3) Is OSA a cause of chronic cough in children? ⋯ There is moderate-quality evidence that common etiologies of chronic cough in children are different from those in adults and are dependent on age and setting. As there are few data relating OSA and chronic cough in children, the panel suggested that these children should be managed in accordance with pediatric sleep guidelines.

Rapid eye movement (REM) sleep behavior disorder (RBD) is characterized by abnormal behaviors emerging during REM sleep that may cause injury or sleep disruption. The diagnosis requires polysomnography (PSG) demonstrating a loss of normal skeletal muscle atonia during REM sleep. RBD results from dysfunction of the brain stem circuits responsible for maintaining normal REM sleep atonia and suppressing behaviors during REM sleep. ⋯ RBD has been linked with narcolepsy and has been associated with a variety of other disorders. The management of RBD focuses on preventive/safety measures, counseling, monitoring for the development of a neurodegenerative disorder, and pharmacotherapy, which is typically effective but not well understood. The purpose of this article is to review and update our current understanding of the clinical features, epidemiology, demographics, pathophysiology, evaluation, diagnosis, differential diagnosis, causes, associations, and the clinical management of RBD.

The introduction of new technologies offers the promise to advance medicine. This occurs alongside improved efforts to control costs of health care by hospital administrators, the Centers for Medicare & Medicaid Services' (CMS) pivot to value programs, and commercial payers' efforts to reduce reimbursement. These trends present a challenge for the pulmonologist, among others, who must navigate increasingly complex and highly scrutinized evaluation processes used to secure new technology (NT). ⋯ It is imperative that all parties involved in the decision process work collaboratively to deploy value added and clinically impactful technologies. Although a physician group might invest in such NT, the capital required often leads such decisions to a larger organization such as a hospital, health-care system, or privately owned entity. This article aims to provide a framework for pulmonary clinicians to better understand the processes that purchasers use to evaluate NT, the pressures that influence their consideration, and what resources may be leveraged toward success.
