Review Meta Analysis
Risk factors for acute exacerbation of idiopathic pulmonary fibrosis: A systematic review and meta-analysis.
Idiopathic pulmonary fibrosis (IPF) is a chronic and progressive fibrotic disease limited to the lungs. The course of disease varies widely, with some patients experiencing acute respiratory deterioration, a condition called acute exacerbations of IPF (AE-IPF). The risk factors contributing to AE-IPF are unclear. This systematic review and meta-analysis investigated the risk factors for AE-IPF. ⋯ Poor pulmonary function, mechanical procedures, higher serum KL-6 and secondary pulmonary hypertension were associated with increased risks of AE-IPF.

Randomized Controlled Trial Multicenter Study
Association of migraine with asthma risk: A retrospective population-based cohort study.
Both migraine and asthma are common health problems in the general population. However, the association between these two disorders is yet to be fully explored. ⋯ Adult patients with migraine are at a higher future risk of asthma development.

Review Case Reports
Organizing pneumonia related to electronic cigarette use: A case report and review of literature.
Electronic cigarettes (e cigarettes) are battery operated devices that produce aerosol by heating a solution typically made up of nicotine, propylene glycol, glycerin and flavouring agents. The use of e cigarettes has risen dramatically in recent years especially among adolescents and young adults. These devices have been marketed as safer alternatives to tobacco smoking by their manufactures despite lack of adequate safety data. ⋯ As the current data on health effects of e cigarettes is limited, case reports can serve important piece of information in this regard. The use of e cigarettes has increased exponentially in recent years and continue to rise; therefore, physicians should be aware of adverse effects and toxicity related to its use.

Randomized Controlled Trial
One minute sit-to-stand test is an alternative to 6MWT to measure functional exercise performance in COPD patients.
Chronic obstructive pulmonary disease (COPD) is frequently associated with a reduced functional exercise performance. Even if this parameter is routinely evaluated using 6-minute walking test (6MWT), new field tests are regularly investigated as alternative tests. The aim of this study was to compare functional exercise performance evaluation by sit-to-stand test (STST) and 6MWT and to evaluate reliability and repeatability of the STST in COPD patients. ⋯ The one minute sit-to-stand test is a valuable alternative to 6MWT to estimate functional exercise performance in COPD patients. The cardiorespiratory demand is different between both tests although the variation of dypsnea is similar. No learning effect was observed for STST.

Comparative Study
Bench evaluation of commercially available and newly developed interfaces for mouthpiece ventilation.
Mouthpiece ventilation represents a valuable treatment for patients needing daytime non-invasive ventilation. This modality is however underused, in part because of limitations in the available equipment. ⋯ They found measurable differences in the ventilation's performances comparing the interfaces for mouthpiece ventilation, which seem to have a minor clinical relevance in the most settings, but should be systematically checked. They validated in-vitro the newly developed mouthpiece with respect to the ventilation performances; a clinical study is needed to investigate the potential advantages we expect from the new mouthpiece.
