Logistic regression analyses were performed to assess the association between respiratory symptoms and illnesses with similar exposure groups, age, duration of work, and smoking among brick kiln workers.Results: A significant number of workers reported experiencing chronic cough (12.3%), chronic phlegm (10.8%), wheezing (9.2%), chronic bronchitis (10.8%), and asthma (3.6%). Interestingly, people with similar exposure groups, such as coal crushers, were almost four times more likely to have chronic coughs and asthma. Also, coal crushers had higher rates of chronic phlegm (odds ratio [OR] 2.89; 95% confidence interval [CI], 1.26-6.61), and chronic bronchitis (OR 2.41; 95% CI, 1.02-5.65). Firemen were also twice as likely to have wheezing and chronic bronchitis. Similarly, individuals transporting red bricks were more likely to report chronic phlegm (OR 2.78; 95% CI, 1.41-5.49). Green brick stacking/carrying was used as the reference group for similar exposure groups.Conclusion: A higher significance of respiratory issues is reported in coalmen, firemen, and red brick loaders. Technology transfer and natural gas substitution are necessary to protect workers.","PeriodicalId":520443,"journal":{"name":"Environmental and occupational health practice","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11841772/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143589595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calibration curves derived from shifts in nominal arrival-time spectra of chemical substances relative to those of water clusters enable quantitative analysis at high concentrations.Methods: This study investigated the adaptability of IMS to real-time monitoring of VOCs in the work environment, using toluene as a test case. Toluene concentrations were measured by IMS at one-minute intervals during a ten-minute simulated cleaning operation.Results: The arrival-time shift was lower at high concentrations because ion production saturates as the toluene concentration approaches the limit of ionizability, with a resulting decrease in slope of the calibration curve. The lower limit of quantification for toluene was assumed to be 13.3 ppm because no arrival-time shift was observed at lower concentrations. The time-averaged toluene concentration measured by IMS for 10 minutes of operation was 45.8 ppm, which is comparable to that measured by gas chromatography-mass spectrometry (GC-MS; 44.3 ppm) within ~3%.Conclusions: Our results indicate that the measurement of toluene concentrations is possible at one-minute intervals by IMS, making it possible to track rapid changes in workplace conditions. Therefore, IMS can measure exposure to VOCs in real-time with an accuracy similar to that of GC-MS.","PeriodicalId":520443,"journal":{"name":"Environmental and occupational health practice","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11841791/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143589484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We applied a stroke prediction model to employees of a Japanese non-iron metal company working at 10 worksites to present health status of the worksite.Methods: We applied a stroke prediction model of the Japan Public Health Center-based Prospective Study to 2,807 male employees without history of cardiovascular disease. We additionally applied models from the Japan Arteriosclerosis Longitudinal Study and from the Suita Study for validation. As the expected value for each employee at a worksite, we calculated the mean of employees' predicted 10-year stroke risk for each worksite. To adjust difference in age distribution, the stroke risk of each worksite was age-adjusted using the direct method. The expected values were presented as the representative value of a worksite with the 95% confidence interval calculated using the bootstrap method. Logistic regression analysis was conducted to explore the reason why a worksite exhibits a high risk. We examined if partial regression coefficients of the worst worksite were affected by modifiable risk factors.Results: Three models predicted similar stroke risks for 10 worksites. Difference in the predicted stroke risk was observed among the worksites even after age-adjustment. Diabetes mellitus was found to affect partial regression coefficient of the worst worksite in any of three prediction models.Conclusion: The stroke prediction model was observed to be a comprehensive tool for presenting a worksite's health status.","PeriodicalId":520443,"journal":{"name":"Environmental and occupational health practice","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11841792/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143589591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The recovery rate of the connected sampler was compared with that of XAD-7. Benzyl alcohol on the filter was extracted, and that in Slim-J resin was desorbed by methanol with an internal standard (N,N-dimethylformamide). Benzyl alcohol was quantified through gas chromatography using a flame ionization detector (GC/FID). Air sampling was conducted by attaching the connected sampler to the chest of a worker during bridge paint film removal.Results: Calibration curves showed linearity with correlation coefficients >0.999. The lower limit of quantification was 0.54 mg/m3 of the airborne concentration at 5-mL desorption with 120-L air sampling. The recovery rates of the connected sampler were 101-103%, whereas those of XAD-7 were 72-78%. The average extraction efficiency from the filters was 105.3%, whereas those from Slim-J were 94.5%. No breakthrough was recognized by aeration at 1 L/min for 120 min. Benzyl alcohol in the sampler was stable for up to 7 days. The sampled air by the connected sampler during bridge paint film removal indicated an isolated peak by GC/FID.Conclusions: The connected sampler is reliable and suitable for measuring levels of personal exposure to benzyl alcohol in vapor and mist phases.","PeriodicalId":520443,"journal":{"name":"Environmental and occupational health practice","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11841778/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143589534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detecting and eradicating Helicobacter pylori infections and implementing a follow-up strategy should be considered by occupational health practitioners. This study aimed to evaluate the cost-effectiveness of adding an H. pylori antibody (HPA) test to current gastric cancer screening using upper gastrointestinal series (UGI) at the workplace in Japan.Methods: The data of Japanese people aged ≥40 years were collected from PubMed and evaluated in two cohorts: UGI (X-ray examination)+HPA test and UGI only. A Markov model was used for the cost-effectiveness analysis of the UGI+HPA test and UGI-only cohorts. The main outcomes were cost, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). The impact of uncertainty was assessed using one-way sensitivity analyses (OWSA) and probabilistic sensitivity analyses (PSA).Results: A base-case analysis showed that the UGI+HPA test strategy was less costly (-US＄1,039 and -US＄1,496) and more effective (0.415 and 0.437 QALYs) than the UGI-only strategy in the 40- and 50-year-old groups, respectively. The UGI+HPA test strategy was assessed as a dominant strategy. In the OWSA, the tornado diagram showed negative expected costs and positive QALY gains within the established ranges for all parameters. In the PSA, more than 95% of the simulations demonstrated ICER <5 million yen (US＄51,674; US＄1=96.76 yen)/QALY.Conclusions: This modeling study suggests that gastric cancer screening using UGI+HPA test followed by eradication and annual opportunistic screening, compared with UGI only, resulted in lower costs and greater QALY gains for both 40- and 50-year-old groups at the workplace.","PeriodicalId":520443,"journal":{"name":"Environmental and occupational health practice","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11841776/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143589586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
