Non-invasive ventilation (NIV) improves survival and quality of life in amyotrophic lateral sclerosis (ALS) patients. The timing of referral to a home ventilation service (HVS), which is in part based on respiratory function tests, has shown room for improvement. It is currently unknown which respiratory function test predicts an appropriate timing of the initiation of NIV. ⋯ SNIP showed the greatest decline prior to NIV indication and PCF significantly differentiated 'NIV-indication' from 'no NIV-indication yet' patients with ALS. Currently used cut-off values might be adjusted and other respiratory function tests such as SNIP and PCF may become part of routine care in patients with ALS in order to avoid non-timely initiation of (non-invasive) ventilation.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of direct switch to indacaterol/glycopyrronium in patients with moderate COPD: the CRYSTAL open-label randomised trial.
Dual bronchodilation combining a long-acting β2-agonist (LABA) and a long-acting muscarinic antagonist (LAMA) is the preferred choice of treatment recommended by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2017 guidelines for the management of patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). The once-daily (q.d.) fixed-dose combination (FDC) of LABA, indacaterol 110 μg and LAMA, glycopyrronium 50 μg (IND/GLY 110/50 μg q.d.) demonstrated superior improvements in lung function, dyspnoea and overall health status and better tolerability against LABA or LAMA monotherapies and combination of LABA and inhaled corticosteroid (ICS) in more than 11,000 patients with moderate-to-severe COPD in several randomised controlled clinical trials. ⋯ IND/GLY demonstrated superior improvements in lung function and dyspnoea after direct switch from previous treatments.

Observational Study
Health related quality of life in patients with idiopathic pulmonary fibrosis in clinical practice: insights-IPF registry.
The INSIGHTS-IPF registry provides one of the largest data sets of clinical data and self-reported patient related outcomes including health related quality of life (QoL) on patients with idiopathic pulmonary fibrosis (IPF). We aimed to describe associations of various QoL instruments between each other and with patient characteristics at baseline. ⋯ Overall, IPF patients under real-life conditions have lower QoL compared to those in clinical studies. There is a meaningful relationship between QoL and various patient characteristics.

Chronic obstructive pulmonary disease (COPD) is a heterogeneous disease characterized by multiple subtypes and variable disease progression. Blood biomarkers have been variably associated with subtype, severity, and disease progression. Just as combined clinical variables are more highly predictive of outcomes than individual clinical variables, we hypothesized that multiple biomarkers may be more informative than individual biomarkers to predict subtypes, disease severity, disease progression, and mortality. ⋯ This comprehensive analysis of two large cohorts revealed that combinations of biomarkers improve predictive value compared with clinical variables and individual biomarkers for relevant cross-sectional and longitudinal COPD outcomes.

Randomized Controlled Trial
Reduction in clinically important deterioration in chronic obstructive pulmonary disease with aclidinium/formoterol.
'Clinically important deterioration' (CID) is a composite endpoint measuring worsening of the key clinical features of chronic obstructive pulmonary disease (COPD), namely lung function, patient-reported outcomes, and exacerbations. ACLIFORM and AUGMENT were two 24-week, randomized, double-blind, phase III studies assessing twice-daily (BID) aclidinium bromide (AB) 400 μg/formoterol fumarate (FF) 12 μg. This pooled post-hoc analysis assessed the effects of AB/FF 400/12 μg on both first and sustained CID events versus placebo and monotherapies in patients with moderate to severe COPD. ⋯ AB/FF 400/12 μg BID may provide greater airway stability and fewer exacerbations or deteriorations in lung function, health status, or dyspnea compared with placebo or monotherapies.
