We aimed to determine the frequency and predictors of exercise limitation after pulmonary embolism (PE) and to assess its association with health-related quality of life (HRQoL) and dyspnea. ⋯ Almost half of patients with PE have exercise limitation at 1 year that adversely influences HRQoL, dyspnea, and walking distance. CPET or 6MWD testing at 1 month may help to identify patients with a higher risk of exercise limitation at 1 year after PE. Based on our results, we believe that the deconditioning that occurs after acute PE could underlie this exercise limitation, but we cannot exclude the fact that this may have been present before PE.

Observational Study
The Power of Flash Mob Research - Conducting a nationwide observational clinical study on Capillary Refill Time in a single day.
Capillary refill time (CRT) is a clinical test used to evaluate the circulatory status of patients; various methods are available to assess CRT. Conventional clinical research often demands large numbers of patients, making it costly, labor-intensive, and time-consuming. We studied the interobserver agreement on CRT in a nationwide study by using a novel method of research called flash mob research (FMR). ⋯ Interobserver agreement on CRT is, at best, moderate. CRT measured at the distal phalanx yielded higher interobserver agreement compared with sternal CRT measurements. FMR proved a valuable instrument to investigate a relatively simple clinical question in an inexpensive, quick, and reliable manner.

Despite accumulating evidence about its adverse health effects, water-pipe tobacco smoking has become very popular among youth. The aim of this study was to compare smoke exposure and the kinetics of exhaled carbon monoxide (eCO) between water-pipe and cigarette smokers under different conditions. ⋯ Our results suggest that water-pipe smoking is associated with significantly higher toxicant exposure than cigarette smoking even in outdoor environments. Furthermore, even passive, indoor water-pipe smoke exposure may have significant health hazards compared with those of active cigarette smoking.

Non-Malignant Pleural Effusions (NMPE): a prospective study of 356 consecutive unselected patients.
Pleural effusion secondary to a nonmalignant cause can represent significant morbidity and mortality. Nonmalignant pleural effusion (NMPE) is common, with congestive heart failure representing the leading cause. Despite this, there are limited data on mortality risk and associated prognostic factors. ⋯ This is the largest prospectively collected series in patients with NMPE, demonstrating that cases secondary to organ dysfunction have extremely high 1-year mortality. In addition, the presence of bilateral and transudative effusions is an indicator of increased mortality. Clinicians should be aware of these poor prognostic features and guide management accordingly.

Interventional pulmonology (IP) is a rapidly evolving subspecialty of pulmonary medicine. In the last 10 years, formal IP fellowships have increased substantially in number from five to now > 30. ⋯ Recognizing the need for more uniform training across the various fellowship programs, a multisociety accreditation committee was formed with the intent to establish common accreditation standards for all IP fellowship programs in the United States. This article provides a summary of those standards and can serve as an accreditation template for training programs and their offices of graduate medical education as they move through the accreditation process.
