Lung cancer screening (LCS) reduces lung cancer-related mortality; however, uptake remains low compared with other cancer screening programmes. In this observational study, we report the impact of timed appointments and reminders on participation in our regional LCS programme.Initial uptake of timed appointments was 53.0% (n=17 274/32 593), higher than previously reported in the UK, while initial uptake of open invitations was 29.8% (n=10 246/34 371). Among initial non-responders, 17.5% (n=4263/24 400) completed triage following a reminder. The increased participation following reminders only partially offset the significant difference in initial uptake between the two appointment types.Timed appointments and reminders are strongly advocated to increase participation in national LCS programmes.

Environmentally persistent free radicals (EPFRs) are combustion products present in substantial numbers on atmospheric particulate matter with half-lives of days to years. The mechanisms linking EPFR exposure and respiratory diseases are unclear, but likely involve oxidative stress. We investigated the mechanisms by which EPFR exposure impact on well-differentiated primary human nasal epithelial cells from subjects sensitive or resistant to oxidant stressors, cultured at an air-liquid interface. We found that EPFR exposure induced mitochondrial reactive oxygen species (mtROS) production; increased mitochondrial DNA copy number; down-regulated mucus production gene, Mucin-5AC (MUC5AC); up-regulated detoxifying gene, cytochrome P450 1A1 (CYP1A1), nuclear factor erythroid 2-related factor 2 (NRF2)-regulated antioxidant pathways including Sirtuin 1 (SIRT1)-Forkhead box O3 (FOXO3), mitophagy, PTEN-induced kinase 1 (PINK1), apoptosis, cyclin-dependent kinase inhibitor p21 (p21), and inflammation, C-C motif chemokine ligand 5 (CCL5). These results indicate that the well-differentiated respiratory epithelium can respond and activate redox reactions when exposed to sublethal concentrations of EPFRs. Increased susceptibility to EPFR exposure is conferred by failure to upregulate the mucin gene, MUC5AC, expression. Pre-treatment with astaxanthin prevented most of the negative impacts caused by EPFRs. Our results demonstrate that EPFRs can induce oxidative stress and cause damage to respiratory epithelium. A dietary antioxidant, astaxanthin, protected cells from EPFR-induced oxidant stress.

Background: Oscillometry may provide the feasible and sensitive tool for objective remote monitoring of paediatric asthma. Methods: Observational study of school-aged healthy, well-controlled and poorly-controlled asthma performing daily home-based oscillometry for 3-4 months, alongside objective measures of asthma control (Asthma Control Questionnaire weekly and Asthma Control Test monthly), medication use and exacerbations. Day-to-day variability calculated as coefficient of variation (CV) for resistance at 5 Hz (R5), reactance at 5 Hz (X5) and area under reactance curve (AX). Our objective was to examine feasibility, whether day-to-day variability was increased in asthma and correlations with asthma control and exacerbation burden. Clinical exacerbation patterns were examined using principal component analysis and k-means clustering of oscillometry, symptoms, breathing parameters and adherence. Results: Feasibility was 74.9±16.0% in health (n=13, 93.7±16.2 days) and 80.6±12.9% in asthma (n=42, 101.6±24.9 days; 17 well-controlled and 27 poorly-controlled asthma). Increased day-to-day variability in all oscillometry indices occurred in asthma versus health (all p≤0.002), with CV R5 the best discriminator (area under receiver operating characteristics curve 0.88, p<0.001). CV R5 increased during exacerbation and correlated with all asthma control measures and exacerbation burden. Correlations remained when examining non-exacerbation oscillometry data. Two exacerbation patterns were found based on oscillometry data in the pre-exacerbation period, characterised by severity of impairment of R5, X5, AX and CV R5 (n=12, more severe). Findings were similar using post-exacerbation period oscillometry data (n=8, more severe). Symptoms did not differ across exacerbation patterns. Conclusions: Home-based oscillometry monitoring was highly feasible over extended periods in school-aged asthmatics. Day-to-day oscillometry variability was increased in asthma compared with health, reflected asthma control and exacerbation burden and identified differing exacerbation patterns.

Improved maternal asthma management in pregnancy may reduce recurrent bronchiolitis and wheeze outcomes in infancy. We assessed whether infant bronchiolitis and wheeze outcomes are influenced by inflammation-guided management intervention, inhaled corticosteroid (ICS) use or exacerbations in pregnancy. A randomised controlled trial (RCT) secondary analysis and observational cohort analysis using the same study population was carried out. Pregnant women (12-23 weeks' gestation) from six centres in Australia were recruited and randomised to inflammation-guided asthma management or usual care between 2013 and 2023. ICS use and asthma exacerbations were reported during pregnancy and postnatally. When infants were 6 (n=691) and 12 (n=606) months of age, respiratory information was collected from parents and medical records. Associations for the RCT and observational analyses were assessed with logistic regression. Guided asthma management in pregnancy was not associated with bronchiolitis or wheeze-related outcomes, for example for recurrent bronchiolitis at 12 months, the intervention OR was 1.04 (95% CI 0.62-1.73). In the observational analyses, ICS use in pregnancy was not associated with respiratory outcomes; however, asthma exacerbations in pregnancy were associated with at least one bronchiolitis episode (adjusted odds ratio (adjOR) 2.20, 95% CI 1.28-3.76) or croup episode (adjOR 4.34, 95% CI 1.89-9.96) at 6 months, and wheeze (adjOR 1.80, 95% CI 1.14-2.84) and increasing wheeze episodes at 12 months (adjOR 1.81, 95% CI 1.17-2.79). Although there was no evidence that guided asthma management or ICS use in pregnancy reduces infant bronchiolitis or wheeze, maternal asthma exacerbations are an important risk factor for these outcomes. Further research is needed to reduce exacerbations in pregnancy.
