Idiopathic pulmonary fibrosis (IPF) is a chronic progressive lung disease with high mortality, uncertain cause, and few treatment options. Studies have identified a significant genetic risk associated with the development of IPF; however, mechanisms by which genetic risk factors promote IPF remain unclear. We aimed to identify genetic variants associated with IPF susceptibility and provide mechanistic insight using gene and protein expression analyses. ⋯ UK Medical Research Council, National Heart, Lung, and Blood Institute of the US National Institutes of Health, Agencia Canaria de Investigación, Innovación y Sociedad de la Información, Spain, UK National Institute for Health Research, and the British Lung Foundation.

Review Meta Analysis
Vitamin D supplementation to prevent asthma exacerbations: a systematic review and meta-analysis of individual participant data.
A previous aggregate data meta-analysis of randomised controlled trials showed that vitamin D supplementation reduces the rate of asthma exacerbations requiring treatment with systemic corticosteroids. Whether this effect is restricted to patients with low baseline vitamin D status is unknown. ⋯ Health Technology Assessment Program, National Institute for Health Research (reference number 13/03/25).

CNS metastases-including brain and leptomeningeal metastases-from epidermal growth factor receptor (EGFR)-mutant non-small-cell lung cancer (NSCLC) are associated with poor prognosis. AZD3759 is a novel EGFR tyrosine kinase inhibitor with high capability to penetrate the blood-brain barrier. We aimed to assess the safety, tolerability, pharmacokinetics, and efficacy of AZD3759 in patients with EGFR-mutant NSCLC with brain and leptomeningeal metastases. ⋯ AstraZeneca.

Randomized Controlled Trial Multicenter Study
A novel formulation of inhaled sodium cromoglicate (PA101) in idiopathic pulmonary fibrosis and chronic cough: a randomised, double-blind, proof-of-concept, phase 2 trial.
Cough can be a debilitating symptom of idiopathic pulmonary fibrosis (IPF) and is difficult to treat. PA101 is a novel formulation of sodium cromoglicate delivered via a high-efficiency eFlow nebuliser that achieves significantly higher drug deposition in the lung compared with the existing formulations. We aimed to test the efficacy and safety of inhaled PA101 in patients with IPF and chronic cough and, to explore the antitussive mechanism of PA101, patients with chronic idiopathic cough (CIC) were also studied. ⋯ Patara Pharma.
