The impact of acute wildfire smoke inhalation on development of chronic disease is unknown. Previously, we have reported lung function decrements in a cohort of adolescent rhesus macaque monkeys that were exposed as infants to the Northern California wildfires (Black, et. al. 2017). For this current study, we hypothesized that pulmonary changes due to early life wildfire smoke exposure would persist into adulthood and lead to transmission of maternal phenotype into offspring. Methods: Adult female rhesus monkeys were born and reared in an outdoor environment within three months prior to the Trinity and Humboldt County summer wildfires in 2008, which produced significant episodes of PM2.5 exposures within one mile of the primate colony. High resolution computerized tomography (CT) imaging of the thoracic cavity was conducted on adult animals only. CT scans were analyzed using Functional Respiratory Imaging to quantify structural changes and functional deficits. A second cohort born in the spring of 2009 served as a control group; biospecimen collection and imaging were conducted in subsequent years to normalize age. Results: CT scans from wildfire smoke-exposed adult monkeys showed significant reductions in lung volume, inspiratory capacity, and ventilation perfusion relative to controls. A significant increase in specific airway radius and blood vessel density was also detected in wildfire smoke-exposed adult monkeys. Conclusions: Our findings demonstrate that early life ambient wildfire smoke exposure results in pulmonary responses that persist into adulthood.

Aim: To explore relationships between FENO and symptoms, asthma, and lung function in wood, foundry, and laboratory animal workers. Method: Workers underwent validated questionnaire, FENO, and spirometry measured to ATS/ERS standards. Associations were examined between FENO >40ppb and work-related respiratory symptoms (WRRS); and between current asthma symptoms (CAS) and either FENO >40ppb, or CAS and FEV1 below the lower limit of normal (LLN). Degree of overlap between workers with FENO >40ppb, FEV1 Results: In total 655 workers took part. Mean age was 39 (SD 12.5) years, 86% were male and 25% current smokers. Overall 40% of workers reported CAS and 20% had elevated FENO. FENO >40ppb was associated with asthma (OR for FENO >40 ppb 2.12, 95% CI 1.19 – 3.78). Nine per cent of workers had both CAS and high FENO: the risk of WRRS was elevated in this group (OR 3.75, 2.01 – 7.00). No increased risk of WRRS was seen in workers with CAS and obstructive spirometry. Among workers with CAS, little overlap existed between those with high FENO and those with low FEV1. Over half those with CAS and high FENO had no previous asthma diagnosis. Conclusion: CAS were common among workers exposed to a range of known occupational allergens. Measurement of FENO in the workplace can be used to help identify symptomatic workers with eosinophilic airway inflammation. A significant proportion of these workers have never been diagnosed with asthma, suggesting there may be a role for FENO in health surveillance for OA.","PeriodicalId":14308,"journal":{"name":"International Journal of Occupational and Environmental Health","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84532073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
