Predicting the incidence rate of acute exacerbation (AE) of idiopathic pulmonary fibrosis (IPF) and its prognosis in patients with non-small cell lung cancer (NSCLC) and IPF is difficult. The aim was to study the incidence of IPF-AE during the clinical course of the disease and its prognosis in patients with both NSCLC and IPF. ⋯ Our study suggested that mGAP index score and cancer stage may predict IPF-AE and its prognosis in patients with NSCLC and IPF.

Randomized Controlled Trial
Response to a combination of oxygen and a hypnotic as treatment for obstructive sleep apnoea is predicted by a patient's therapeutic CPAP requirement.
Upper airway collapsibility predicts the response to several non-continuous positive airway pressure (CPAP) interventions for obstructive sleep apnoea (OSA). Measures of upper airway collapsibility cannot be easily performed in a clinical context; however, a patient's therapeutic CPAP requirement may serve as a surrogate measure of collapsibility. The present work aimed to compare the predictive use of CPAP level with detailed physiological measures of collapsibility. ⋯ Therapeutic CPAP requirement, as a surrogate measure of pharyngeal collapsibility, predicts the response to non-anatomical therapy (oxygen and eszopiclone) for OSA.

Review Meta Analysis
Mucoactive agents for chronic, non-cystic fibrosis lung disease: A systematic review and meta-analysis.
Inhaled mucoactive agents are used in respiratory disease to improve mucus properties and enhance secretion clearance. The effect of mannitol, recombinant human deoxyribonuclease/dornase alfa (rhDNase) and hypertonic saline (HS) or normal saline (NS) are not well described in chronic lung conditions other than cystic fibrosis (CF). The aim of this review was to determine the benefit and safety of inhaled mucoactive agents outside of CF. ⋯ Mannitol improved mucociliary clearance in asthma and bronchiectasis, while the effects of N-acetylcysteine were unclear. In chronic lung diseases outside CF, there are small benefits of mannitol, NS and HS. Adverse effects of rhDNase suggest this should not be administered in non-CF bronchiectasis.

Asthma, chronic obstructive pulmonary disease (COPD) and obstructive sleep apnoea (OSA) are the most common respiratory disorders worldwide. Given demographic and environmental changes, prevalence for each is likely to increase. Although exact numbers are not known, based on chance alone, many people will be affected by both lower airways obstruction and concomitant upper airway obstruction during sleep. ⋯ Although much work needs to be done, given the above, Respirologists, Sleep Medicine and Primary Care providers must be vigilant for overlap syndromes. Accurate diagnosis of, for example, OSA as a cause of nocturnal symptoms in a patient with asthma is likely to limit further ineffective titration of medications for asthma. Moreover, prompt treatment of OSA in the overlap syndromes will not only offer symptomatic benefit of OSA, but also improve symptoms and healthcare resource utilization attributable to obstructive lung disease, and in COPD, it may reduce mortality.
