A reactive posture for addressing risk undermines biosecurity and contributes to public distrust in science. This problem is not new. A temporal offset between scientific advancement and oversight of associated risks was described more than a century ago. In 1922, the American sociologist, William Ogburn, coined the term, \"cultural lag.\" Cultural lag was premised on the interconnectedness of technology and society and referred to a period of maladjustment between the introduction of a new technology and societal responses to mitigate its downsides. We examine the consequences of cultural lag for risk governance in the life sciences by looking at three recently introduced technologies, CRISPR-Cas9 gene editing, the proposed creation of mirror life, and microbiome engineering. Our observations lead to three recommendations for addressing cultural lag. The first recommendation is structural, namely, consolidation of governmental oversight on emerging technologies; the second is goal-oriented, that is, a call for a holistic form of horizon scanning; and the third concerns process and calls for implementation of deliberative democratic principles and practices. By pursuing an anticipatory governance regime, with policymaking closely aligned to and coordinated with technology breakthroughs, we enhance research safety and security while promoting innovation, and as a secondary benefit, help to restore public trust in science.</p>","PeriodicalId":10452,"journal":{"name":"Cold Spring Harbor perspectives in medicine","volume":" ","pages":""},"PeriodicalIF":4.9,"publicationDate":"2026-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149135340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This narrative review synthesizes current evidence across epidemiology, definitions, clinical phenotypes, assessment, and management, with dedicated consideration of children and adolescents. PTLD is common: Studies report abnormal spirometry in ∼60% of TB survivors and persistent, activity-limiting dyspnea in a sizeable minority. Outcomes are generally worse in low- and middle-income settings. The 2019 international consensus definition-\"evidence of chronic respiratory abnormality attributable at least in part to prior TB\"-has catalyzed research and service development; a newer research definition proposes a structured, three-domain approach (symptoms, radiology, lung function) and introduces \"post-TB lung abnormality\" for single-domain findings. PTLD encompasses heterogeneous patterns, including fibrosis, cavitation with chronic pulmonary aspergillosis risk, bronchiectasis, airflow obstruction, tracheobronchial stenosis, pleural disease, vascular complications, and pulmonary hypertension. Assessment should integrate symptom review, exercise capacity, oximetry, spirometry (with Global Lung Initiative [GLI] reference standards), and context-appropriate imaging, alongside targeted microbiology and echocardiography where indicated. Evidence for disease-modifying therapy remains limited; however, pulmonary rehabilitation improves function and symptoms, and selected patients may benefit from inhaled bronchodilators or surgical interventions. A \"treatable traits\" framework-spanning pulmonary, extrapulmonary, and behavioral risk domains-offers a pragmatic, person-centered strategy while high-quality trials mature. In children, TB during critical periods of lung development confers lasting functional and growth impacts, underscoring the need for age-specific screening and follow-up.

Evidence suggests that asymptomatic TB could be contributing to transmission, although further research is needed. While defining symptom status remains imprecise, individuals with asymptomatic TB present distinct diagnostic and treatment challenges. Asymptomatic pulmonary TB typically involves more limited disease, lower bacillary burden, and difficulty producing sputum, reducing the sensitivity of current sputum-based tests. Novel diagnostic approaches, including alternative sampling and molecular tools, are under development. Treatment uptake and adherence are another concern, as individuals feel well and derive no immediate symptomatic benefit, increasing the risk of poor initiation and completion.
