Clinical Trial
Transesophageal bronchoscopic ultrasound-guided fine needle aspiration for diagnosis of sarcoidosis.
Several studies have reported that specimens from mediastinal lesions located adjacent to the esophagus can be sampled using an ultrasound bronchoscope instead of an ultrasound endoscope. ⋯ Transesophageal bronchoscopic ultrasound-guided fine needle aspiration is feasible, safe and accurate for the diagnosis of stage I/II sarcoidosis.

Comparative Study Clinical Trial
Agreement between spirometers: a challenge in the follow-up of patients and populations?
Long-term cohort studies and lung function laboratories are confronted with the need for replacement of spirometers. Lack of agreement between spirometers might affect the longitudinal comparison of data, notably when replacing conventional by portable spirometers. ⋯ This study suggests fair agreement between the handheld and the conventional spirometer. Differences slightly exceeding limits for FEV1 in 2 EO devices might be considered mostly irrelevant for clinical practice. However, the systematically lower FVC and FEV1 observed with EO may be significant for epidemiological studies, thus justifying inspection before replacing devices.

Water pipe is a traditional method of tobacco use, which is epidemically spreading throughout Europe. There are scarce data about the use of water pipe and its relation to other addictive behaviors among young adults in Western countries. ⋯ Water pipe smoking is common among young adults and strongly associated with cigarette smoking and cannabis consumption.

Comparative Study
Predictors of 1-year mortality at hospital admission for acute exacerbations of chronic obstructive pulmonary disease.
Acute exacerbations of chronic obstructive pulmonary disease (AE-COPD) are related to high mortality, especially in hospitalized patients. Predictors for severe outcomes are still not sufficiently defined. ⋯ Age, male sex, prior hospitalization for AE-COPD in the last 2 years, prior recorded congestive heart failure, hypercapnia and elevated levels of urea at hospital admission are independent predictors of mortality within the first year after admission.

The impact of pulmonary hypertension (PH) on survival has been demonstrated in severe cases with idiopathic pulmonary fibrosis (IPF) who were referred for transplantation. However, whether PH is a predictor of survival remains unclear in milder cases. ⋯ Higher MPAP and lower %FVC at the initial evaluation were significant independent prognostic factors of IPF. The current results suggested the importance of the initial evaluation of PH for patients with IPF.
