Emerging evidence suggests disparities in COPD outcomes between rural and urban populations, but no prior review has synthesised these differences globally. Five databases (Medline, Embase, Emcare, CINAHL and Cochrane Central) were searched in May 2025. Eligible peer-reviewed studies directly compared rural and urban populations in at least one of four measures of COPD burden: prevalence, symptom burden, exacerbations or mortality. Study quality was assessed and narrative synthesis was conducted due to heterogeneity in outcome measures. Of 1339 screened studies, 32 met inclusion criteria, spanning 13 countries. COPD prevalence was higher rurally in 83% (15/18) of studies, with 11/15 demonstrating statistical significance. This pattern was consistent across geographical distributions. Total exacerbation rates were higher rurally in 60% (3/5) of studies, although hospitalisations varied significantly. 50% (6/12) of studies reported higher hospitalisation rates in urban areas and 5/12 studies reporting higher rates in rural areas. 86% (6/7) of studies demonstrated higher mortality rurally and symptom burden was higher amongst rural residents in 67% (4/6) of studies; however, the majority of these were conducted in the USA. This review highlights consistent rural-urban inequalities in COPD prevalence and outcomes, reflecting the impact of healthcare inequities, socioeconomic deprivation and environmental exposures on COPD burden in rural areas. Targeted interventions promoting equitable healthcare access, health education, transition to cleaner fuels and rural access to smoking cessation and pulmonary rehabilitation services are essential to mitigate these disparities and improve outcomes in rural populations.</p>","PeriodicalId":12166,"journal":{"name":"European Respiratory Review","volume":"35 180","pages":""},"PeriodicalIF":10.4,"publicationDate":"2026-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13126127/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147766725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental studies indicate that cumulative and dissipated energy, rather than isolated pressures or volumes, drive lung injury. Observational and registry data consistently link higher mechanical power with increased mortality in acute respiratory distress syndrome and mixed intensive care unit populations, with thresholds of ∼16-18 J·min<sup>-1</sup> associated with increased risk. Normalised indices (<i>e.g.</i> mechanical power per predicted body weight or per compliance) often outperform absolute mechanical power as predictors of outcome. Strategies to minimise mechanical power include individualised positive end-expiratory pressure titration, driving pressure limitation, and an optimised respiratory rate. Complementing traditional physiological analysis, this review highlights the emerging role of technological integration, specifically closed-loop ventilation and artificial intelligence-driven prediction models, as essential tools to bridge the gap between theoretical mechanical power concepts and bedside application.Mechanical power provides a unifying physiological framework that integrates volume, pressure, flow and frequency into a single descriptive measure of ventilatory load. While higher mechanical power is consistently associated with worse outcomes, current evidence does not support titrating ventilation to pre-defined numerical power thresholds, and prospective randomised trials are required to determine whether mechanical power-informed strategies improve patient-centred outcomes.

Its impact, however, extends far beyond the neonatal period and far beyond the lungs. Children, adolescents and adults born very preterm often follow diverse developmental trajectories that diverge from typical postnatal growth. These trajectories often display early airflow limitation, as well as features of increased cardiovascular vulnerability and altered multisystemic profiles. Although common respiratory labels such as asthma are often applied to these patients, evidence highlights distinct pathobiological mechanisms rooted in arrested alveolar and vascular growth, with a possible contribution from persistent airway inflammation and oxidative stress. Extrapulmonary involvement, including cardiovascular, neurodevelopmental, neurosensory, renal and metabolic domains, further shapes long-term outcomes and should be systematically integrated into long-term monitoring. Yet, despite improving survival and growing recognition of this multisystemic burden, current evidence remains insufficient to design a dedicated, holistic, multidisciplinary follow-up programme tailored to the diverse subgroups of preterm-born individuals. Increasing awareness among healthcare professionals of the long-term implications of prematurity is essential to ensure that these patients receive appropriate and coordinated attention. Emerging lines of research, spanning new preventive and therapeutic options, advanced imaging, mechanistic studies, and long-term cohort designs, hold promise in elucidating the biological determinants of disease.

Converging evidence shows that dysregulated innate and adaptive immunity orchestrates every stage of the fibrotic cascade. Roughly 20% of PF susceptibility loci map to immune regulatory genes, including Toll-interacting protein, interleukin (IL)-1 receptor antagonist, Toll-like receptor-3, complement receptor-1 and tumour necrosis factor-α (TNF-α), indicating that genetically primed host defence pathways predispose to maladaptive repair. Recurrent epithelial injury triggers a type 1 inflammatory response that gradually shifts toward type 2-skewed wound healing; the resulting cytokine milieu rich in transforming growth factor-β, IL-13, IL-6 and platelet-derived growth factor reprogrammes fibroblasts into collagen-secreting myofibroblasts. Spatial-omic profiling of PF lungs corroborates this model, revealing niches where profibrotic macrophages, T-helper cells and inflammatory fibroblasts colocalise within a stiff, collagen-rich matrix. Beyond their direct antimesenchymal actions, the current therapeutics pirfenidone and nintedanib also temper innate and adaptive immune signalling. Proof of concept for sharper immunomodulation now comes from recent phase III trials of nerandomilast, a highly selective phosphodiesterase-4B inhibitor that preserved forced vital capacity and downregulated TNF-α, IL-6 and IL-17 networks. These results demonstrate that immune pathway modulation can complement existing antifibrotics and invigorate efforts to align mechanism-based therapies with patient-specific immune endotypes, steered by genetics, cellular phenotypes and circulating biomarkers. This review synthesises current understanding of how immunity initiates, amplifies and perpetuates PF, linking genetic and mechanistic insights to emerging therapeutic opportunities. A deeper grasp of immune-epithelial-fibroblast crosstalk is essential for transforming disease-slowing care into genuinely disease-modifying intervention.</p>","PeriodicalId":12166,"journal":{"name":"European Respiratory Review","volume":"35 180","pages":""},"PeriodicalIF":10.4,"publicationDate":"2026-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13058739/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147638069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
