One of the most significant complications of preterm birth is bronchopulmonary dysplasia (BPD). The pathophysiology of BPD has changed in recent years as advances in neonatal care have led to increased survival of smaller, more preterm, infants who display alterations to alveolar and pulmonary microvascular development. It is becoming clear that infants with 'new' BPD experience lung disease that persists into later childhood, however, the oldest of these children are just now entering young adulthood and therefore the longer term pulmonary implications remain unknown. The role of lung function testing in the identification and subsequent management of patients with lung disease resulting from a neonatal classification of BPD is reviewed based on the underlying pathophysiology of the disease.

It remains difficult to differentiate between chronic obstructive pulmonary disease (COPD) and asthma in clinical practice, especially in a primary care setting. The purpose of this study was to develop a new scoring system for differentiating between COPD and asthma, and to evaluate its effectiveness. ⋯ The new scoring system that was developed in this study may be a useful tool for differentiating between COPD and asthma in primary care.

Treatment with pirfenidone may slow the decline in vital capacity and increase progression-free survival (PFS) in idiopathic pulmonary fibrosis (IPF). The effects of combination therapy with inhaled N-acetylcysteine (NAC) and pirfenidone are unclear. We assessed the effects of this combination therapy in patients with advanced IPF. ⋯ Combination treatment with inhaled NAC and oral pirfenidone reduced the rate of annual FVC decline and improved PFS in patients with advanced IPF.

A single nucleotide polymorphism (SNP) rs35705950 in the promoter of Mucin 5B (MUC5B) has been reported to be associated with idiopathic pulmonary fibrosis (IPF) mainly in Caucasian populations. This study was conducted to confirm the association between rs35705950 and IPF in a Japanese population. ⋯ The association between rs35705950 and IPF was also present in this Japanese cohort, but was not as strong as the German counterpart. To our knowledge, this is the first study to successfully validate the association between rs35705950 and IPF in a Japanese ethnicity.

Exacerbations of chronic obstructive pulmonary disease (COPD) are one of the commonest causes of emergency hospital admission and are associated with high rates of readmission. Rehabilitation in the peri- and early post-hospitalization setting may counteract the deleterious consequences of an acute hospital admission and target modifiable risk factors for readmission such as physical inactivity, reduced exercise capacity and impaired physical function. Pulmonary rehabilitation in the peri-hospitalization period can improve exercise capacity and health-related quality of life and can also reduce rates of readmission. ⋯ However, recent trials showing less positive results and observational data questioning acceptability may challenge prevailing enthusiasm. This review examines the role of pulmonary rehabilitation in the peri- and early post-hospitalization setting, considering the modifiable risk factors for readmission, the latest evidence regarding rehabilitation in the acute setting, issues around acceptability and uptake, and alternative strategies to help deliver rehabilitation to more patients. The acceptability and effectiveness of pulmonary rehabilitation offered that post-exacerbation could be improved by overcoming issues around the setting, timing and format of rehabilitation approaches, including their integration with self-management interventions.
