RESUMEN
BackgroundHealthcare personnel (HCP) are at high risk for respiratory infections through occupational exposure to respiratory viruses.AimWe used data from a prospective influenza vaccine effectiveness study in HCP to quantify the incidence of acute respiratory infections (ARI) and their associated presenteeism and absenteeism.MethodsAt the start and end of each season, HCP at two Israeli hospitals provided serum to screen for antibodies to influenza virus using the haemagglutination inhibition assay. During the season, active monitoring for the development of ARI symptoms was conducted twice a week by RT-PCR testing of nasal swabs for influenza and respiratory syncytial virus (RSV). Workplace presenteeism and absenteeism were documented. We calculated incidences of influenza- and RSV-associated ARI and applied sampling weights to make estimates representative of the source population.ResultsThe median age of 2,505 participating HCP was 41 years, and 70% were female. Incidence was 9.1 per 100 person-seasons (95%â¯CI:â¯5.8-14.2) for RT-PCR-confirmed influenza and 2.5 per 100 person-seasons (95%â¯CI:â¯0.9-7.1) for RSV illness. Each season, 18-23% of unvaccinated and influenza-negative HCP seroconverted. The incidence of seroconversion or RT-PCR-confirmed influenza was 27.5 per 100 person-seasons (95%â¯CI:â¯17.8-42.5). Work during illness occurred in 92% (95%â¯CI:â¯91-93) of ARI episodes, absence from work in 38% (95%â¯CI:â¯36-40).ConclusionInfluenza virus and RSV infections and associated presenteeism and absenteeism were common among HCP. Improving vaccination uptake among HCP, infection control, and encouraging sick HCP to stay home are important strategies to reduce ARI incidence and decrease the risk of in-hospital transmission.

AIMS OF THE STUDY: Limited knowledge exists regarding exposures to non-therapeutic chemicals by women planning to conceive, or during pregnancy or breastfeeding. The Swiss Teratogen Information Service (STIS) provides information to healthcare professionals about medications and other exposures during pregnancy or breastfeeding. This study aimed to describe the queries on non-therapeutic chemicals addressed to the STIS over the past two decades. METHODS: Using data from the STIS for the years 2000 to 2019, we conducted a descriptive analysis of all queries related to women's exposures to non-therapeutic chemicals during pregnancy planning, pregnancy or breastfeeding. RESULTS: Over two decades, the STIS database recorded 320 exposures to chemicals. Workplace settings accounted for over 60% of queries, followed by exposures at home (20%). In almost half (48%) of the queries, more than one chemical was mentioned, totalling 885 chemicals across these 320 queries. Commonly mentioned chemicals included isopropanol, acetone and lead. Solvents were the leading category of products (16%), followed by cleaning products (10%), paints (8%) and insecticides (5%). The follow-up data showed five diverse cases of congenital malformations, accounting for 4.0% (5 out of 125) of the sample, a figure in line with the background risk of malformations in the general population. CONCLUSIONS: This study emphasises the importance of conducting research that comprehensively captures the highly heterogeneous exposures to non-therapeutic chemicals during pregnancy and suggests that attention should be given not only to professional settings, but also to domestic contexts.

BACKGROUND: Against the backdrop of the debate on extending working life, it is important to identify vulnerable occupational groups by analysing inequalities in healthy life years. The aim of the study is to analyse partial life expectancy (age 30-65) [1] free of musculoskeletal diseases (MSD) and [2] free of cardiovascular diseases (CVD) in occupational groups with different levels of physical and psychosocial exposures. METHODS: The study is based on German health insurance claims data from 2015 to 2018. The study population comprises all employed insured persons aged 18 to 65 years (N = 1,528,523). Occupational exposures were assessed using a Job Exposure Matrix. Life years free of MSD / CVD and life years with MSD /CVD during working age were estimated using multistate life tables. RESULTS: We found inequalities in MSD-free and CVD-free life years, with less disease-free years among men and women having jobs with high levels of physical and psychosocial exposures. Men with low physical exposures had 2.4 more MSD-free and 0.7 more CVD-free years than men with high physical exposures. Women with low psychosocial exposures had 1.7 MSD-free and 1.0 CVD-free years more than women with high psychosocial exposures. CONCLUSIONS: Employees in occupations with high physical and psychosocial demands constitute vulnerable groups for reduced life expectancy free of MSD and CVD. Given the inequalities and high numbers of disease-affected life years during working age, the prevention potential of occupational health care and workplace health promotion should be used more extensively.

BACKGROUND: Adolescents living in agricultural communities may be at risk for the adverse effects of pesticide exposure because they are involved in agriculture either as a career or to support their families. OBJECTIVE: The purpose of this study was to investigate the association of farm activities related to pesticide exposure on blood cholinesterase (ChE) levels among adolescents from farming families in the north of Thailand. MATERIAL AND METHODS: This cross-sectional study included 336 adolescents aged 12-19 years from farming families in Chiang Dao District, Chiang Mai Province. Data on pesticide exposure was collected using a questionnaire, and blood ChE activity was assessed using a ChE reactive paper test kit via fingerstick blood sampling. RESULTS: Overall, 51.2% of participants had abnormal blood ChE levels. Univariable logistic regression analysis revealed that pesticide-related activities on farms associated with abnormal ChE levels were mixing/spraying (OR=10.54; 95%CI=4.63-23.99), assisting or working in areas with pesticide application (OR=5.54; 95%CI=3.45-8.89), and harvesting (OR=3.70; 95%CI=2.35-5.82). In a multivariable model (Nagelkerke R2=0.374), mixing/spraying (OR=4.90; 95%CI=2.03-11.83) and assisting or working in areas with pesticide application (OR=2.61; 95%CI=1.49-4.57) were significantly associated with abnormal ChE levels, but harvesting (OR=1.48; 95%CI=0.84-2.61) was not significant after adjusting for sex, age in years, and entering or walking through a farm. CONCLUSIONS: The findings indicated that Thai adolescents living in farming families are at risk of pesticide exposure, particularly those involved in agricultural activities such as pesticide applicators. An intervention and measure to raise awareness and reduce the risk of pesticide exposure in adolescents is required.

Background: Some occupational and environmental exposures could increase the risk of chronic obstructive pulmonary disease (COPD) and hypertension in various work and living environments. However, the effect of exposure to multiple exogenous harmful substances on COPD and hypertension co-morbidities remains unclear. Methods: Participants were selected from eight hospitals in five provinces in China using a multistage cluster sampling procedure. Participants' demographic, exposure, and disease information were collected through questionnaires, spirometry, and blood pressure examinations. Demographic data were used as matching factors, and 1:1 matching between the exposed and non-exposed groups was performed by employing propensity score matching (PSM) to minimize the influence on the results. A one-way chi-squared analysis and multifactorial logistic regression were used to analyze the association between the exposure to exogenous harmful substances (metals and their compound dust, inorganic mineral dust, organic chemicals, and livestock by-products) and the co-morbidity of COPD and hypertension. Results: There were 6,610 eligible participants in the final analysis, of whom 2,045 (30.9%) were exposed to exogenous harmful substances. The prevalence of co-morbidities of COPD and hypertension (6.0%) in the exposure group was higher than their prevalence in the total population (4.6%). After PSM, exogenous harmful substance exposure was found to be a risk factor for the co-morbidity of COPD and hypertension [odds ratio (OR) = 1.347, 95% confidence interval (CI): 1.011-1.794], which was not statistically significant before PSM (OR = 1.094, 95% CI: 0.852-1.405). Meanwhile, the results of different outcomes showed that the association between hypertension and exogenous harmful substance exposure was not statistically significant (OR = 0.965, 95% CI: 0.846-1.101). Smoking (OR = 4.702, 95% CI: 3.321-6.656), history of a respiratory disease during childhood (OR = 2.830, 95% CI: 1.600-5.006), and history of respiratory symptoms (OR = 1.897, 95% CI: 1.331-2.704) were also identified as risk factors for the co-morbidity of COPD and hypertension. Conclusion: The distribution of exogenous harmful substance exposure varies in the population, and the prevalence of co-morbidities is generally higher in susceptible populations. Exposure to exogenous harmful substances was found to be a key risk factor after adjusting for demographic confounders.

The study investigated the health care workers' knowledge, attitudes, and practice levels regarding occupational protection against antineoplastic drugs (ADs) via analysis of latent classes and their influencing factors. A convenience sampling method was used to select healthcare workers from 7 hospitals in southern China between April and August 2023. A questionnaire based on literature analysis, brainstorming, and Delphi method was used to investigate the knowledge, practice, and attitudes of healthcare workers exposed to ADs for appropriate occupational protection intervention, followed by latent class analysis. The factors influencing latent classes were identified via single-factor analysis and multiple logistic regression. A total of 322 healthcare workers from departments using ADs were surveyed. The knowledge score associated with occupational protection against ADs was 31.95â ±â 7.38. The attitude score was 21.08â ±â 2.729, while the practice score was 36.54â ±â 9.485. The overall score was 89.57â ±â 15.497. The healthcare workers were divided into 4 latent classes based on their knowledge, attitude, and practice associated with occupational protection measures against ADs. Healthcare workers in the 4 categories showed significance differences based on professional title, marital status, educational background, and frequency of exposure to ADs (Pâ <â .05). The knowledge, attitude, and practice levels of healthcare workers engaged in ADs at work can be divided into 4 latent classes. Despite their increased awareness of the hazards associated with ADs and their attitudes toward protection, the healthcare workers displayed poor knowledge and implementation of occupational protection measures.

Background: Most studies on viral infections among livestock handlers have focused on occupational exposure from inadvertent contact with infected animals. Consequently, little emphasis is given to the effect of their lifestyle on the acquisition of other blood-borne viruses. Objectives: To determine the prevalence and assess risk factors for HIV, HBV and HCV infections among livestock handlers in Ibadan, Nigeria. Methods: Blood samples were collected from 265 livestock handlers between October 2016 to April 2017 in Ibadan. The samples were tested for the presence of antibodies to HIV and HCV; and surface antigen to HBV using ELISA. Structured questionnaire was administered to collect information on risk factors associated with the transmission of these viruses. Data analysis was carried out using Chi-square test and logistic regression to determine the association between risk factors and predictors of infection (p < 0.05). Results: Of 265 participants, 11 (4.2%), 29 (10.9%) and 13 (4.9%) individuals tested positive for HIV, HBV and HCV infections respectively. Two (0.8%) of the participants were coinfected with HIV and HBV while 1(0.4%) was coinfected with both HBV and HCV. Individuals who travelled frequently in the course of Livestock trades had a higher rate of HIV infection. Conclusions: A high Infection with HIV, HBV and HCV is common among the study participants. There is a need for continued surveillance and awareness creation on preventive measures against these viruses.

Objective: To study the prevalence of occupational pneumoconiosis in Qinhuangdao from 1961 to 2020 and offer a foundation for developing occupational pneumoconiosis prevention and control methods. Methods: In December 2020, the data of occupational pneumoconiosis cases diagnosed by medical institutions with occupational disease diagnosis qualifications in Qinhuangdao City from 1961 to 2020 were collected Anova or kruskal-Walls tests and chi-square tests were used for inter-group comparisons of continuous and categorical variables, and LSD tests or Tamhane T2 tests were used for multiple comparisons. Results: Between 1961 and 2020, 384 cases of pneumoconiosis were documented in Qinhuangdao, of which 382 (99.5%) patients were men and 2 (0.5%) were women. The average dust service duration is 15 (9, 25) years, with a minimum duration of 0.5 years and a maximum duration of 49 years; Cases were primarily distributed in Qinglong Manchu Autonomous County (187 cases, 48.7%) and the Haigang district (160 cases, 41.7%) ; Type of pneumoconiosis was silicosis (340 cases, 88.5%), mainly 273 cases (71.1%) of stage I, 88 cases (22.9%) of stage II, and 23 cases (6.0% of stage III) ; Cases of Phase II and III and with short lengths of service are mainly concentrated in medium-sized, small, private limited liability companies and collective enterprises. Rrock work (166 cases, 43.2%), and loading kiln workers (42 cases, 10.9%) were the main types. Conclusion: Because the distribution of pneumoconiosis cases in Qinhuangdao city is concentrated and the length of service is decreasing, it is important to enhance the oversight of important area, businesses, industries, and job categories in line with the growth of the region's mineral resources.

INTRODUCTION: The aim of this study was to conduct a systematic literature review to find the association between pesticide exposure and the incidence of suicide in agricultural workers, focusing on analyzing the profile of agricultural workers, the countries with the highest number of publications and, especially, the link between occupational exposure to pesticides, the degradation of mental health and suicide among agricultural workers. METHODS: A systematic literature review was conducted following the PRISMA protocol using Scopus, Web of Science, and PubMed databases, where 33 articles were screened to compose the final portfolio. RESULTS: There is a strong link between pesticide exposure and suicide in agricultural workers. Smoking, alcohol consumption, exposure time, and marital status influence the decision to die by suicide. Brazil and the US lead the ranking in publications, demonstrating that it is not a problem only for developing countries. Organophosphates are the main pesticides used, and they degrade an enzyme crucial for the nervous system, which can result in mental disorders and consequent suicide in agricultural workers. CONCLUSION: There is a need for stricter norms for the commercialization and use of pesticides. There is also a need for providing training to agricultural workers on the application and storage of pesticides, and to communicate about the compounds and the consequences of pesticides to mental health.

INTRODUCTION: The main objective of the study was to estimate the burden of occupational tuberculosis infection in high-risk occupational workers and to identify risk factors associated with the prevalence of Mycobacterium tuberculosis complex (MTBC). METHODOLOGY: An analytical cross-sectional study was conducted among high-risk occupational workers including veterinarians, abattoir workers, animal handlers, livestock farmers, and microbiology laboratory workers. Sputum samples were collected from 100 participants and polymerase chain reaction (PCR) tests were done to diagnose tuberculosis (TB) infection. Data on potential risk factors was collected in a pre-designed questionnaire. The MTBC prevalence ratio was estimated. Logistic regression analysis was conducted to identify risk factors and the crude odds ratio (OR) was calculated. RESULTS: Among the 100 enrolled high risk occupational workers, the prevalence of MTBC was 46% (95% CI: 35.98-56.25). Living in a joint family (OR 3.85, 95% CI: 1.58-9.37), and use of unpasteurized milk (OR 3.42, 95% CI: 1.4-8.39), were significantly associated with MTBC infection. CONCLUSIONS: Tuberculosis is a significant health burden in high-risk occupational groups, especially animal handlers and laboratory workers, in Lahore, Pakistan. The study also emphasized the need for formal work-related training, and enhanced zoonotic TB awareness among occupational workers.

BACKGROUND: Healthcare workers are at risk of occupational exposure to blood and other body fluids after sustaining needlestick injury which constitutes a risk for transmission of blood-borne pathogens such as Hepatitis B virus, Hepatitis C virus or Human Immune-deficiency Virus. OBJECTIVES: To assess the prevalence, response, and associated factors of needlestick injury by medical sharps among healthcare workers in Orotta National Referral Hospital, Asmara, Eritrea. METHODS: Cross sectional study was conducted between September and December 2017 among healthcare workers. This was a census study whereby a total of 383 healthcare workers who had contact with sharp medical equipment were taken as study population. An aided self-administered questionnaire, checklist and key informant interviews were used as data collection tools. Analysis was done using Statistical Package for Social Sciences, version 22. Bivariate and binary logistic regression analyses were carried out and the level of significance was set at P < .05. RESULTS: The prevalence of needlestick injury 12 months preceding the study was 37.1% (134/361). Midwives had the highest occurrence (45%) among others while adult intensive care unit were found to have higher prevalence of needlestick injury (61.5%) as compared to the other sections. As an immediate response to needlestick injury, only 15.7% washed the injured part with soap and water. The factors associated with needlestick injury include age > 40 years (AOR = .314, p = .05), marital status (married (AOR = 0.595, p = .05)), additional duty that made healthcare workers rush during working hours (AOR = 2.134, p = .002) and back bone problem (AOR = 2.239, p = .002). CONCLUSION: The overall finding of the study indicated that there was a great risk of contracting blood-borne infections among the healthcare workers especially midwives. Therefore, there is need for adequate supply of safety engineered devices, Hepatitis B vaccine, better reporting, and surveillance of needlestick injury cases at the hospital. Moreover, further research on assessment of the knowledge, attitude, and practice of healthcare workers toward occupational safety and health, particularly needlestick injury, is necessary.

Asthma is a significant public health concern. This study identified the provinces with the highest morbidity and mortality rates due to asthma among the working-age population (15-69 years) in the Republic of Ecuador. The secondary objective was to explain the possible differences attributable to occupational exposure. This nationwide ecological study was conducted in 24 provinces between 2016 and 2019. Government databases were used as sources of information. Age-standardized rates were calculated for codes J45 and J46. The hospitalization morbidity rate for asthma decreased from 6.51 to 5.76 cases per 100,000 working-age population, and the mortality rate has consistently been low and stable from 0.14 to 0.15 deaths per 100,000 working-age population. Geographic differences between the provinces were evident. The risk of hospitalization and death due to asthma was higher in the Pacific coast (Manabí with 7.26 and 0.38, Esmeraldas with 6.24 and 0.43, Los Ríos with 4.16 and 0.40, El Oro with 7.98 and 0.21, Guayas with 4.42 and 0.17 and the Andean region (Azuay with 6.33 and 0.45, Cotopaxi (5.84 and 0.48)). The high rates observed in provinces with greater agricultural and industrial development could be national heterogeneity's main determinants and act as occupational risk factors. The contribution of occupational hazards in each province should be examined in depth through ad hoc studies. The findings presented here provide valuable information that should prompt further detailed studies, which will assist in designing public policies aimed at promoting and safeguarding the respiratory health of the population, particularly that of workers. We believe that this study will inspire the creation of regional networks for the research and surveillance of occupational health.

BACKGROUND: Occupation is an important risk factor for lung cancer. This knowledge is mainly based on studies conducted on men, with the results being generalized to women. AIMS: We aimed to identify the relationship between different occupations and lung cancer in women. METHODS: Pooling study in which data were pooled from six case-control studies conducted at 13 Spanish hospitals and 1 hospital in Portugal. Each woman's longest held job was coded as per the ISCO-08. Results were adjusted for age, smoking, and exposure to residential radon. RESULTS: The study population comprised 1262 women: 618 cases and 644 controls. The reference group were white-collar workers. The adjusted multivariate analysis showed a higher risk of developing lung cancer among teaching professionals (odds ratio [OR]: 4.36; 95% confidence interval [CI] 1.73-11.02), cooks (OR: 3.59; 95% CI 1.52-8.48), domestic cleaners and helpers (OR: 2.98; 95% CI 1.54-5.78), homemakers (OR: 2.30; 95% CI 1.26-4.21) and crop farmers, livestock farmers and gardeners (OR: 2.06, 95% CI: 1.11-3.81). For adenocarcinoma, the highest risk was observed in teaching professionals, and for small-cell carcinoma, the highest risk was observed in cooks. Higher risks were observed for small-cell carcinoma compared to other histological types. CONCLUSIONS: Some occupations may be associated with an increased risk of lung cancer in women and this risk could vary by histologic subtype; however, further research is needed to confirm these associations. In any case, protection measures must be implemented in the workplace aimed at reducing the risk of lung cancer among women workers, and more studies exclusively focused on women are warranted.

Occupational exposure to toxic elements can adversely affect health. The current study evaluated blood concentrations of potentially toxic elements (PTE) including As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, Sb, Sn, and Zn in formal and informal workers. Additionally, the study investigated the associations between blood PTE concentrations and reported health outcomes in the study population. The exposed group included women engaged in informal jewelry welding within their homes in Limeira, São Paulo state, Brazil (n = 36) and men who worked at a steel company in Volta Redonda, Rio de Janeiro state, Brazil (n = 22). The control group comprised residents of the same neighborhoods as the workers but without occupational exposure to chemicals (n = 28 in Limeira; n = 27 in Volta Redonda). Triple Quadrupole Inductively Coupled Plasma Mass Spectrometry (TQ ICP-MS) was used to determine PTE concentrations in blood samples. Glycemia, insulin, and lipid profile tests were performed. All participants completed questionnaires on household risk and reported morbidity. The blood concentrations of Cd, As, and Pb, as well as glycemia, were higher in informal workers than in control subjects. No significant differences were observed between formal workers and control subjects. A robust Poisson regression model, adjusted for variables suggested by a Directed Acyclic Graph, disclosed associations of blood lead and arsenic concentrations with the prevalence of neurological manifestations in Limeira. Blood lead levels > 2.6 µg dL-1 were associated with 2.3 times the prevalence of self-reported neurological manifestations (95 % CI: 1.17-4.58; p = 0.02) than lower blood lead concentrations. Furthermore, a positive association between blood cadmium concentrations and glycemia was observed. Informal occupational exposure to these elements may indicate an increased risk of developing diseases. Monitoring exposure and implementing interventions to reduce PTE exposure in the work environment represent significant steps toward prevention.

It remains unclear how ambient air pollution may affect the prevalence of obstructive ventilatory dysfunction (OVD) among workers. We aim to assess the association of a comprehensive set of ambient air pollutants with OVD prevalence in workers and to explore the potential interactive effects of the occupational factors. This is a population-based cross-sectional study among 305,022 participants from the Guangdong Province, China. Mixed-effects models were used to obtain differences in the OVD risk associated with a 10 µg/m3 increase in ambient air pollution. We found that for each 10 µg/m3 increase in PM2.5, PM10, PM coarse, O3, and NO2 concentrations, the odds ratio (OR) for OVD in workers is 1.324 (95 % confidence interval (CI), 1.282-1.367), 1.292 (95 % CI, 1.268-1.315),1.666 (95 % CI, 1.614-1.719), 1.153 (95 % CI, 1.142-1.165), and 1.023 (95 % CI, 1.012-1.033). We observed that young participants (18-38 years old), women, participants with longer years of service (>48 months), participants working in large enterprises, professional skills workers, and production and manufacturing workers have higher estimated effects. In addition, we also found that workers exposed to high temperatures have higher estimated effects under air pollutants exposure, while workers exposed to noise have higher estimated effects under PM2.5, PM10, NO2, and O3 exposure. Workers exposed to dust have a lower risk of developing OVD under exposure to ambient air pollutants compared to those not exposed. Our results indicate that ambient air pollution increases the risk of OVD in workers. Moreover, air pollutants exhibit a greater estimated effect among workers exposed to high temperatures or noise.

INTRODUCTION: Exposure to hazardous substances in the workplace can result in injuries and fatalities. This study aimed to investigate the characteristics and trend of occupational exposures reported to the Dutch Poisons Information Centre and to investigate whether the COVID-19 pandemic had an impact on the trend. METHODS: A retrospective analysis of all acute occupational exposures reported to the Dutch Poisons Information Centre between 1 January 2016 and 31 December 2022 was performed. Data on patient and exposure characteristics, symptoms and treatment recommendations were analyzed. RESULTS: Between 2016 and 2022, the Dutch Poisons Information Centre received 5,508 calls regarding acute occupational exposures. The annual number of calls on acute occupational exposures almost doubled over the years studied (from 475 in 2016 to 936 in 2022). During and after the COVID-19 pandemic (March 2020-December 2022), the number of calls stabilized, but the upward trend was not significantly affected. There were an estimated 0.20 calls per 1,000 human exposure calls per month (95 per cent confidence interval: -0.14; 0.53). Victims were often exposed through multiple routes, with inhalation being the most common route (44 per cent), followed by ocular (32 per cent) and dermal contact (30 per cent). Acids (1,138 exposures) and alkalis (912 exposures) were often involved. The Dutch Poisons Information Centre had information on 6,334 patients, although the total number of exposed patients was not known as some victims did not seek medical assistance, or were treated by healthcare professionals who did not consult our Centre. At the time of contact, 13 per cent (n = 795) of the patients reported no symptoms, 76 per cent (n = 4,805) reported mild to moderate symptoms and 3 per cent (n = 183) reported potentially severe symptoms. Information on symptoms was missing for 9 per cent (n = 551) of the patients. Hospital observation and treatment were recommended for 5 per cent (n = 325) of the patients. DISCUSSION: This study highlights the necessity for poisoning prevention strategies to reduce the number of work-related incidents involving hazardous substances. CONCLUSION: The continuing increase in the number of workplace incidents involving hazardous substances is of concern. A comprehensive and multidisciplinary approach should be taken to gain a full understanding of occupational exposure to hazardous substances and to identify risk factors.

OBJECTIVE: This study aimed at investigating the relationship between occupational exposure to external ionising radiation and central nervous system (CNS) tumours mortality in healthcare workers working in France. DESIGN AND SETTING: The Occupational Radiation-Induced Cancer in Medical staff (ORICAMs) nested case-control study was conducted based on the dosimetric records of the national register of occupational dosimetry (Système d'information de la surveillance de l'exposition aux rayonnements ionisants). PARTICIPANTS AND METHODS: 33 CNS tumour deaths occurred between 2002 and 2012 among the ORICAMs cohort composed of 164 015 healthcare workers. Each case was matched to five controls alive at the time of the corresponding case's death, based on sex, year of birth, date of enrolment in the cohort and duration of follow-up. All participants were badge monitored for external radiation exposure, expressed in Hp(10). Conditional logistic regression was used to analyse the dose-response relationship between radiation dose and CNS mortality. RESULTS: Cases were exposed to a mean cumulative career radiation dose of 5.8±13.7 (max: 54.3) millisievert (mSv) compared with 4.1±15.2 (142.2) mSv for controls. No statistically significant association was found between CNS tumour mortality and cumulative whole-body career dose (OR=1.00, 95% CI 0.98 to 1.03), duration of exposure (OR=1.03; 95% CI 0.95 to 1.12) or age at first exposure (OR=0.98; 95% CI 0.91 to 1.06). CONCLUSION: We found no evidence of an association between external radiation exposure and CNS tumour risk in healthcare workers. Limitations of the study include low statistical power and short duration of follow-up.

INTRODUCTION: The workplace's health hazard remains a significant concern to workers in the mining industry, where miners are continually exposed to various kinds of exposure sources. METHOD: First, the determinants of miners' health were systematically extracted from 259 publications, comprising chemical, physical, ergonomic, and psychosocial stressors, vulnerability factors, and common health outcomes. Then, 16 meta-analyses were performed to ascertain the epidemiological evidence for associations between four stressors and three health outcomes. The seven top contributing factors affecting miners' health were identified through 166 available prospective studies. Finally, based on the classic and domestic measurement scales, a cross-sectional survey of 559 Chinese miners was conducted to determine the core psychosocial predictors. In addition to the traditional mechanisms, complex interactive networks among the antecedents and consequences and the reversed effects of consequences were also obtained, where 379 strong association rules were yielded via the Apriori algorithm. RESULTS: The results showed that occupational dust, NO2, heavy metals, heat, vibration, awkward posture, and job stress are significant risk factors associated with individuals' health conditions. Psychological capital, coping style, job demand, social support, organizational support, justice, and culture are core psychosocial predictors of miners. CONCLUSIONS: This study presents a case for identifying the most significant occupational risk factors related to individuals' health, which could be extended and applied to other industries, as working populations around the world are suffering from various chemical, physical, ergonomic, and psychosocial stressors. PRACTICAL APPLICATIONS: Identifying the significant occupational risk factors affecting workers' health conditions is essential for comprehensive occupational health risk assessment and management. Therefore, this study could be important for health management in mines and other industries.

Epidemiological findings have determined the linkage of fine particulate matter (PM2.5) and the morbidity of hypertension. However, the mode of action and specific contribution of PM2.5 component in the blood pressure elevation remain unclear. Platelets are critical for vascular homeostasis and thrombosis, which may be involved in the increase of blood pressure. Among 240 high-PM2.5 exposed, 318 low-PM2.5 exposed workers in a coking plant and 210 workers in the oxygen plant and cold-rolling mill enrolled in present study, both internal and external exposure characteristics were obtained, and we performed linear regression, adaptive elastic net regression, quantile g-computation and mediation analyses to analyze the relationship between urine metabolites of polycyclic aromatic hydrocarbons (PAHs) and metals fractions with platelets indices and blood pressure indicators. We found that PM2.5 exposure leads to increased systolic blood pressure (SBP) and pulse pressure (PP). Specifically, for every 10 µg/m3 increase in PM2.5, there was a 0.09 mmHg rise in PP. Additionally, one IQR increase in urinary 1-hydroxypyrene (1.06 µmol/mol creatinine) was associated with a 3.43 % elevation in PP. Similarly, an IQR increment of urine cobalt (2.31 µmol/mol creatinine) was associated with a separate 1.77 % and 4.71 % elevation of SBP and PP. Notably, platelet-to-lymphocyte ratio (PLR) played a mediating role in the elevation of SBP and PP induced by cobalt. Our multi-pollutants results showed that PAHs and cobalt were deleterious contributors to the elevated blood pressure. These findings deepen our understanding of the cardiovascular effects associated with PM2.5 constituents, highlighting the importance of increased vigilance in monitoring and controlling the harmful components in PM2.5.
