Whether the use of rapid on-site cytologic evaluation (ROSE) increases the diagnostic yield of transbronchial needle aspiration (TBNA) remains unclear. This article is a systematic review of studies describing the utility of ROSE in subjects undergoing TBNA. ⋯ The use of ROSE neither improved the diagnostic yield nor reduced the procedure time during TBNA. However, the use of ROSE was associated with fewer number of needle passes during EBUS-TBNA and overall lower requirement for additional bronchoscopy procedures during TBNA to make a final diagnosis.

Screening for Lung Cancer: CHEST Guideline and Expert Panel Report.
Low-dose chest CT screening for lung cancer has become a standard of care in the United States in the past few years, in large part due to the results of the National Lung Screening Trial. The benefit and harms of low-dose chest CT screening differ in both frequency and magnitude. The translation of a favorable balance of benefit and harms into practice can be difficult. Here, we update the evidence base for the benefit, harms, and implementation of low radiation dose chest CT screening. We use the updated evidence base to provide recommendations where the evidence allows, and statements based on experience and expert consensus where it does not. ⋯ Evidence suggests that low-dose CT screening for lung cancer results in a favorable but tenuous balance of benefit and harms. The selection of screen-eligible patients, the quality of imaging and image interpretation, the management of screen-detected findings, and the effectiveness of smoking cessation interventions can affect this balance. Additional research is needed to optimize the approach to low-dose CT screening.

Emerging literature suggests that sleep-disordered breathing (SDB) worsens over the course of pregnancy and is associated with adverse maternal and fetal outcomes. Earlier studies, using mainly snoring as a surrogate marker for SDB, have shown an increase in the prevalence of SDB during pregnancy compared with that in the pregravid state. More recently, prospective observational studies in which the investigators ascertained SDB by using complete polysomnography have shown a prevalence ranging from approximately 17% to 45% in the third trimester. ⋯ Some studies also have identified a relationship between maternal SDB and the delivery of infants who are small for gestational age. Aside from a few small interventional studies of CPAP in pregnant patients with gestational hypertension, little currently is known about whether treatment of SDB during pregnancy improves clinical outcomes for the mother and/or baby. Additional current knowledge gaps include elucidating underlying mechanisms of maternal SDB, determining optimal treatment strategies, and understanding the trajectory of SDB after delivery.

A clinical database is a repository of patient medical and sociodemographic information focused on one or more specific health condition or exposure. Although clinical databases may be used for research purposes, their primary goal is to collect and track patient data for quality improvement, quality assurance, and/or actual clinical management. ⋯ We consider approaches to deciding the base unit of data collection, creating consensus around variable definitions, and structuring routine clinical care to complement database aims. We conclude with an overview of regulatory and security considerations for clinical databases.
