Lung cancer screening in advanced chronic obstructive pulmonary disease: helpful or harmful?
Commonly in medicine we encounter situations where a potential intervention may not be in the patient’s best interests due to the balance of benefits and harms. In screening, there is the additional goal of the intervention being beneficial to the screened population as a whole.1 With the recent endorsement from the UK National Screening Committee for lung cancer screening (LCS) with low-dose CT (LDCT) in the UK,2 and with LCS efforts stepping up worldwide, it is imperative we understand how best to offer screening to the ‘correct’ individuals. The benefits of LCS have been well demonstrated in the litera...

Respiratory effects of air pollution: time to stop this deadly trajectory
The Global Burden of Disease Study has estimated that over 500 million subjects, around 7% of the global population, are affected by chronic respiratory diseases, with substantial individual and societal costs concerning morbidity, disability and mortality.1 Identifying and mitigating potentially modifiable risk factors are crucial in preventing the associated public health burden. Extensive literature has provided compelling evidence that air pollution, especially fine particulate matter (PM)2.5 (diameter <2.5 µm), is a leading risk factor for the incidence and mortality of acute and chronic respiratory diseases,...

The rise of the novel antihyperglycaemic agents: are patients with chronic obstructive pulmonary disease the next to benefit? The role of novel antihyperglycaemic drugs in cardiology and diabetes is well recognised, and laboratory studies have suggested possible mechanisms by which these drugs could reduce chronic obstructive pulmonary disease (COPD) exacerbations in patients with type 2 diabetes mellitus. A population-based cohort study by Pradhan et al (BMJ 2022;379:e071380) used primary care and hospital databases to compare 3 novel antihyperglycaemic drugs (glucagon-like peptide 1 (GLP-1) receptor agonists, n=1252; dip...

Invasive pulmonary infection caused by Trichoderma longibrachiatum
A 38-year-old woman presented with a 1-month history of progressive cough and phlegm. She was an office worker. She denied the presence of comorbidities including diabetes, renal disease, malignancy and acquired immune deficiency syndrome. She underwent chest CT scan (figure 1A) 2 weeks before admission, having been taking moxifloxacin treatment for 12 days without improvement in symptoms. A repeat CT scan at admission showed significant progression of the lung lesions compared with previous imaging (figure 1B). Sputum culture was negative. Laboratory investigations revealed NK cells, CD4+, CD8+ lymphocytes and the CD4+/CD...

Tracheal stenosis after endobronchial ultrasound-guided transbronchial needle aspiration
A 78-year-old man was referred to our hospital to study a pulmonary nodule in the left lower lobe, suspicious for malignancy. An endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was carried out for the study, during the procedure samples were taken from lymph node stations 4R (lower paratracheal right), 7 (subcarinal) and 11 L (interlobar left) using a 22-gauge needle. The histological results ruled out lymph node involvement. There were no immediate complications, however, the patient developed a dry cough 72 hours after the procedure. After assessment by the multidisciplinary lung tumour commi...

COPD in Africa: risk factors, hospitalisation, readmission and associated outcomes--a systematic review and meta-analysis
Conclusion This study not only highlights specific risk factors for COPD risk in Africa but also demonstrates the paucity and absence of research in several countries in a continent with substantial COPD-related mortality. Our findings contribute towards the development of evidence-based clinical guidelines for COPD in Africa. PROSPERO registration number CRD42020210581. (Source: Thorax)

Effects of enhanced recovery after surgery plus pulmonary rehabilitation on complications after video-assisted lung cancer surgery: a multicentre randomised controlled trial
Conclusions Adding pulmonary rehabilitation to enhanced recovery after surgery appears to be effective in reducing the incidence of PPCs, but not LOS. Standard integration of pulmonary rehabilitation into thoracic enhanced recovery after surgery is a promising approach to PPC prophylaxis. Trial registration number ChiCTR1900024646. (Source: Thorax)

Cluster analysis of transcriptomic datasets to identify endotypes of idiopathic pulmonary fibrosis
Background Considerable clinical heterogeneity in idiopathic pulmonary fibrosis (IPF) suggests the existence of multiple disease endotypes. Identifying these endotypes would improve our understanding of the pathogenesis of IPF and could allow for a biomarker-driven personalised medicine approach. We aimed to identify clinically distinct groups of patients with IPF that could represent distinct disease endotypes. Methods We co-normalised, pooled and clustered three publicly available blood transcriptomic datasets (total 220 IPF cases). We compared clinical traits across clusters and used gene enrichment analysis to identif...

Diagnosis and treatment outcomes from prebronchodilator spirometry performed alongside lung cancer screening in a Lung Health Check programme
Conclusions Delivering spirometry alongside lung cancer screening may facilitate earlier diagnosis of COPD. However, this study highlights the importance of confirming AO by postbronchodilator spirometry prior to diagnosing and treating patients with COPD and illustrates some downstream challenges in acting on spirometry collected during an LHC.
