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}

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}

Although health literacy influences health behaviors, studies comparing health literacy levels between shift and fixed-day workers and investigating whether differences in health behaviors between these 2 groups are mediated by health literacy are lacking.Methods: This cross-sectional study used a self-administered questionnaire in a large-scale manufacturing company. Overall, 2152 manual workers aged 18-64 years were enrolled in this study (961 and 1191 fixed-day and shift workers, respectively). Logistic regression structural equation models were used for analyzing the mediating role of health literacy in the relationship between shift work and health behaviors.Results: Shift and fixed-day workers did not show differences in age-adjusted health literacy. Compared with fixed-day workers, the odds ratios of shift workers for leisure time exercise, not currently smoking, having breakfast, brushing their teeth, and eating green and yellow vegetables were 0.85 (95% CI, 0.70-1.02), 0.68 (95% CI, 0.56-0.80), 0.63 (95% CI, 0.52-0.76), 0.79 (95% CI, 0.65-0.95), and 0.58 (95% CI, 0.48-0.70), respectively.

We defined insomnia based on the International Classification of Sleep Disorders, third edition, sleep apnea syndrome (SAS) with a simple 4-variable screening tool, and restless legs syndrome (RLS) with RLS/Willis-Ekbom disease diagnostic criteria. Investigated factors included sleep duration, driving characteristics, caffeine types (foods and beverage) and amounts, caffeine intake timing, State-Trait Anxiety Inventory (STAI), individual stress, and other covariates.Results: The prevalence of suspected SAS was 23.2% (n = 154), and that of RLS was 0.8% (n = 5). After excluding those, chronic insomnia symptoms were present in 36/505 drivers (7.1%). After adjusting for covariates, a logistic model demonstrated that drinking habits [odds ratio (OR), 6.21; 95% CI, 1.07-35.8], caffeine intake before sleep (OR, 2.65; 95% CI, 1.09-6.45), sleep duration on days off (OR, 1.44; 95% CI, 1.01-2.05), and STAI score (OR, 12.8; 95% CI, 2.53-64.2) were significantly associated with chronic insomnia symptoms. STAI was significantly positively correlated with individual stress, such as family worries (r = 0.22), relationships with non-partners (r = 0.28), and health (r = 0.23).Conclusions: Our study revealed that one-fourth of male truck drivers had sleep disorders that require further medical evaluation.

There have been reports on the effects of surface functional groups in evaluating the physicochemical properties of microplastics, but no reports have evaluated their chronic effects. We performed intratracheal instillation in rats to evaluate the acute and chronic effects on the lungs of microplastics with different surface functional groups.Methods: Unmodified, NH2-modified, and COOH-modified polystyrene particles with a particle size of 1 μm were intratracheally instilled into the lungs of rats. Rats were dissected at 3 days, 1 week, 1 month, 3 months, and 6 months after exposure to analyze inflammatory cells and lung injury factors in bronchoalveolar lavage fluid (BALF) and to observe histopathological findings in the lungs.Results: A significant increase in the number of inflammatory cells in BALF was observed up to 1 week after exposure to the NH2-based modified polystyrene compared with the negative control group. A significant increase was observed 3 days after exposure, and histopathological findings in the lungs also showed an influx of inflammatory cells into the alveolar space in the acute phase, but not in the chronic phase. In in vitro studies using RAW cell lines, NH2-based modified polystyrene also induced the highest oxidative stress compared with unmodified and COOH-based modified polystyrene.Conclusions: These results suggest that these polystyrenes do not have high pulmonary toxicity, although there are differences in toxicity due to differences in surface functional groups only in the acute phase.","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/PMC11894927/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143080399","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}

Outcomes of interest were associations between suicide death and occupational skill level, assessed as a 5-level variable, and educational attainment. Logistic regression models were used to estimate these associations before and after adjusting for educational attainment, age, and sex, in each racial/ethnic subpopulation.Results: We found a significant gradient in suicide death across occupational skill levels, with lower-skill occupations associated with higher suicide rates than higher-skill occupations. This gradient was more pronounced among non-Hispanic White (NHW) people and non-Hispanic Black (NHB) people than Hispanic people. However, upon controlling for educational attainment, this association was attenuated, indicating that the initial link was likely confounded by education.Conclusions: The results suggest that educational attainment is a more robust predictor of suicide risk than occupational skill level.

The 2-way interaction terms \"state functionary × occupational status (the International Socioeconomic Index of Occupational Status [ISEI], the Standard International Occupational Prestige Scale [SIOPS], and the Erikson and Goldthorpe class categories [EGP])\" were added to examine whether being a state functionary could moderate the relationship between occupational status and depression.Results: Occupational status was negatively correlated with depression (ISEI: coefficient = -0.03; 95% CI, -0.04 to -0.02; SIOPS: coefficient = -0.01; 95% CI, -0.02 to -0.002; EGP: coefficient = 0.12; 95% CI, 0.08 to 0.15).

The first 3 steps, including the movements of the arms, legs, trunk, and pelvis, were recorded using an RGB camera, and the gait features were identified. Using these gait features and fall histories, a stratified k-fold cross-validation method was used to ensure balanced training and test data, and the area under the curve (AUC) and 95% CI were calculated.Results: Of 77 gait features in the first 3 steps, we found 3 gait features in men with an AUC of 0.909 (95% CI, 0.879-0.939) for fall risk, indicating an \"excellent\" (0.9-1.0) classification, whereas we determined 5 gait features in women with an AUC of 0.670 (95% CI, 0.621-0.719), indicating a \"sufficient\" (0.6-0.7) classification.Conclusions: These findings suggest that fall risk prediction can be developed based on ML and the first 3 steps in men; however, the accuracy was only \"sufficient\" in women.
