Workers with at least 2 check-ups were included, excluding those with other renal dysfunctions. Proximal tubular dysfunction was defined as a B2M-U of 300 μg/g creatinine or higher in 2 or more consecutive check-ups. A multivariable Cox proportional-hazards regression model with time-dependent covariates was performed to analyze the relationship between Cd-B levels and the time to onset of proximal tubular dysfunction, adjusting for age, sex, and smoking history.Results: Of the 338 workers, 238 met the study eligibility criteria for the analyses. The geometric mean of Cd-B was 1.97 μg/L. The Cox proportional hazards analysis demonstrated that higher time-dependent Cd-B levels were significantly associated with an increased risk of proximal tubular dysfunction, with a hazard ratio of 1.17 (95% CI: 1.06-1.29).Conclusions: Higher Cd-B levels are associated with an increased risk of proximal tubular dysfunction in workers exposed to cadmium, indicating an increased risk of renal disease under the current industrial health management in Japan. Continuous monitoring and improved management of cadmium exposure are necessary to protect workers' health even in developed countries such as Japan.","PeriodicalId":16632,"journal":{"name":"Journal of Occupational Health","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11977533/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143557127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rat model experimental study also indicated that OT and acetoaceto-o-toluidine are potent bladder carcinogens. Multiple mechanisms of OT-related bladder cancer have been proposed: metabolic activation to reactive metabolites that bind DNA and proteins, mutagenicity, oxidative DNA damage, chromosomal damage, and cytotoxicity by OT. Recent comprehensive analyses of DNA adducts in rats identified a number of common oxidative DNA adducts, including 8-OHdG, in the rat urothelium and indicated that oxidative stress may play a crucial role in the development of urinary cancer caused by OT. The skin permeability of 6 aromatic amines (o-toluidine, aniline, p-toluidine, o-anisidine, 2,4-dimethylaniline, and o-chloroaniline) was examined with the use of a 3-dimensional (3D) reconstructed human skin model; ~70%-80% of the 6 aromatic amines had permeated through the 3D skin within 8 hours. Genotoxic potency testing in a human urothelial cell line using γ-H2AX, a marker of DNA damage, suggested that OT exhibited strong γ-H2AX generation.Conclusions: Prolonged dermal exposure to OT along with other genotoxic aromatic amines over many years may contribute to the development of bladder cancer.","PeriodicalId":16632,"journal":{"name":"Journal of Occupational Health","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11858003/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143389948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The intensity of PWHS was assessed using self-administered questionnaires. The participants were followed up from October 2021 to October 2022 to evaluate the incidence of absenteeism and presenteeism based on the level of PWHS.Results: The study findings revealed that higher PWHS significantly correlated with lower presenteeism, indicating better work productivity. Conversely, the relationship between PWHS and absenteeism was less clear, with no consistent trend observed across different levels of PWHS intensity.Conclusions: Enhanced PWHS was associated with reduced presenteeism among Japanese workers, underscoring the importance of workplace health support for improving employee productivity. This finding emphasizes the need for companies to focus on health promotion activities and recognize the potential of PWHS as a performance indicator in corporate health management.","PeriodicalId":16632,"journal":{"name":"Journal of Occupational Health","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12012702/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We present a previously unreported case of chronic paronychia with 2 separate digital pilonidal sinuses resulting from multiple embedded hair fragments in the eponychium of a dog groomer, who had been repeatedly treated with antibiotics with no success and ended up having surgical treatment. The objective of this study is to remind readers of this rare but possible occupational disease, particularly among employees working with hair, and to emphasize the importance of preventive measures to prevent its occurrence. Intraoperatively, a crescent of eponychial skin parallel to the proximal nail fold was excised, which incorporated the sinuses. Additionally, the nail plate was removed, and multiple hair fragments were retrieved from the nail folds. At the follow-up, the infection had resolved, and nail growth had resumed. Additional animal hair was found in the nail folds, as the patient continued to work without protective gloves. This case highlights the importance of considering embedded hair as a potential cause for chronic paronychia in individuals with occupations involving hair cutting and grooming. Chronic hand infection poses a risk of infection contaminating clients or patients; for example, a veterinarian should not operate with an infected hand. The costs of sickness absences are considerable for all the stakeholders. The use of protective gloves, hand hygiene, skin care, and thorough removal of loose hair fragments should be emphasized for workers in professions dealing with animal or human hair.","PeriodicalId":16632,"journal":{"name":"Journal of Occupational Health","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11827112/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142829126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
