Objective: To understand the diagnosis of suspected occupational diseases reported in Guangzhou from 2014 to 2019, so as to provide theoretical basis and technical support for the supervision of suspected occupational disease reports. Methods: By cluster sampling, the suspected occupational disease report card, occupational disease report card and pneumoconiosis report card reported by Guangzhou from January 1, 2014 to December 31, 2019 in the occupational disease and occupational health information monitoring system were collected for matching analysis to understand the diagnosis of suspected occupational disease patients. Results: From 2014 to 2019, a total of 1426 suspected occupational cases in 7 categories and 32 species were reported in Guangzhou. The average number of reported cases per year was about 240. The main diseases of suspected occupational diseases were suspected occupational noise deafness (68.44%, 976/1426) , suspected occupational chronic benzene poisoning (16.48%, 235/1426) , suspected occupational other pneumoconiosis (4.84%, 69/1426) , suspected occupational silicosis (3.23%, 46/1426) and suspected occupational welder pneumoconiosis (1.82%, 26/1426) . The diagnostic rate required to enter the occupational disease diagnostic program is 36.61% (522/1426) , and the diagnostic rate is 59.20% (309/522) . In 2019, the diagnosis rate of suspected occupational diseases was the lowest (23.92%, 61/255) , Huadu District was the lowest (8.33%, 9/108) , suspected occupational pneumoconiosis was the lowest (28.03%, 44/157) , the diagnosis rate of suspected occupational diseases reported by the Centers for Disease control and prevention was the lowest (17.43%, 19/109) , and the diagnosis rate of suspected occupational diseases reported by outpatient treatment was the lowest (22.22%, 2/9) . The suspected occupational diseases reported by institutions outside Guangzhou did not enter the occupational disease diagnosis procedure. Suspected occupational skin diseases, suspected occupational diseases caused by physical factors and suspected occupational tumors were diagnosed, and the diagnosis rate of occupational disease prevention and control institutions was the highest (94.87%, 37/39) . Conclusion: The main types of suspected occupational diseases reported during these six years are noise deafness, chronic benzene poisoning and pneumoconiosis. The overall diagnosis rate and diagnosis rate of suspected occupational diseases are not high. It is suggested to improve the network direct reporting system of suspected occupational diseases and strengthen the follow-up management and supervision of suspected occupational diseases.

Objective: Demonstrate the results obtained after the training of the workers of a textile company on the risks associated with noise. Methodology: Population intervention study, reported in the first half of 2019, in a sample of 288 workers. Results: In view of the strategies defined, we obtained a 70% increase in the number of workers who proved knowledge about the risks of noise and a 60% increase in the number of workers who started using PPE correctly. Conclusion: Training in the work context is fundamental in the prevention of occupational disease

Ergonomic parameters of the pathologist’s workplace as important factors in the prevention of occupational musculoskeletal diseases

More than 80% of pathologists suffer from various manifestations of disorders of the musculoskeletal system. The daily duties of pathologists include several hours of work at a microscope and a computer. Microscopes are often not optimized for ergonomics and do not allow the doctor to take the correct sitting position, most often working with a microscope requires leaning forward. To study the ergonomic properties of the workplace of a pathologist and develop specific practical recommendations for long-term work at a microscope. The study included microscopes with an adjustable and non-adjustable angle of inclination of the tube and height-adjustable chairs. We identify following ergonomic parameters: pathologist height; angle of inclination of the back of the chair; angle of inclination of the microscope tube; angle of inclination of the neck; chair height. The study included 21 participants. Statistical processing and analysis were made using single-factor and multifactorial correlation analysis. A strong positive linear correlation was identified (r=0.80; p<0.05) between the height of test person and angle of inclination of the microscope tube. A strong positive linear correlation was established (r=0.91; p<0.05) between the test person height and the angle of inclination of the neck for microscopes with non-adjustable 31°-angle of inclination of the tube. For microscopes with non-adjustable 45°-angle of inclination of the tube a strong polynomial correlation of the second degree (r=0.85; p<0.05) was found. A moderate negative linear correlation was found between the height of the pathologist and his tilt angle neck with both adjustable and non-adjustable tube angle of the microscope. In this study for the first-time exact correlation dependencies between key ergonomic parameters of pathologist's workplace were evaluated. This study showed that only microscopes with an adjustable angle of inclination of the tube allow to achieve an optimal body position.

HBM4EU Occupational Biomonitoring Study on e-Waste-Study Protocol.

Workers involved in the processing of electronic waste (e-waste) are potentially exposed to toxic chemicals. If exposure occurs, this may result in uptake and potential adverse health effects. Thus, exposure surveillance is an important requirement for health risk management and prevention of occupational disease. Human biomonitoring by measurement of specific biomarkers in body fluids is considered as an effective method of exposure surveillance. The aim of this study is to investigate the internal exposure of workers processing e-waste using a human biomonitoring approach, which will stimulate improved work practices and contribute to raising awareness of potential hazards. This exploratory study in occupational exposures in e-waste processing is part of the European Human Biomonitoring Initiative (HBM4EU). Here we present a study protocol using a cross sectional survey design to study worker’s exposures and compare these to the exposure of subjects preferably employed in the same company but with no known exposure to industrial recycling of e-waste. The present study protocol will be applied in six to eight European countries to ensure standardised data collection. The target population size is 300 exposed and 150 controls. Biomarkers of exposure for the following chemicals will be used: chromium, cadmium and lead in blood and urine; brominated flame retardants and polychlorobiphenyls in blood; mercury, organophosphate flame retardants and phthalates in urine, and chromium, cadmium, lead and mercury in hair. In addition, the following effect biomarkers will be studied: micronuclei, epigenetic, oxidative stress, inflammatory markers and telomere length in blood and metabolomics in urine. Occupational hygiene sampling methods (airborne and settled dust, silicon wristbands and handwipes) and contextual information will be collected to facilitate the interpretation of the biomarker results and discuss exposure mitigating interventions to further reduce exposures if needed. This study protocol can be adapted to future European-wide occupational studies.

On occupational diseases in medical workers in the Republic of Bashkortostan

Introduction. The work of medical workers belongs to the most complex, responsible types of human activity. It is associated with the impact of a complex of adverse factors: chemical, biological, physical, the severity and intensity of labour. Due to the high occupational risk, the problem of the formation and preservation of the health of medical workers is urgent. The aim of the work is to determine the dynamic characteristics of occupational morbidity and its structure among medical workers of the Republic of Bashkortostan for 2013-2020. Materials and methods. The occupational morbidity rate among medical workers during 2013-2020 was studied with the materials of the professional centre of the Republic: a notification on the establishment of a final diagnosis of chronic occupational disease and a consolidated annual report on the activities of central occupational pathology. Statistical processing of the results was carried out using the «Statistika 8» application software package. Results. The average annual incidence of occupational morbidity is 0.92±0.12 cases per 10 thousand health workers. They occupied an average of 7.0% of all occupational diseases established over the years in the Republic. The incidence rate tends to decrease. Among occupational patients of health workers, 73.9% are nurses, 15.3% are healthcare staff, 10.8% are doctors. Allergic diseases dominate the nosological structure of occupational diseases. They make up 63.3% of the total pathology, half of which is in bronchial asthma. Discussion. In medical workers, infection occurs through direct contact with a sick patient or biological material. Allergic responses occur to the presence of drugs and disinfectants. Occupational disease tuberculosis was diagnosed at the age of 43.3±6.4 years and experience of 16.6 years; hepatitis at the age of 38.2 years and experience 15.0 years; bronchial asthma - at the age of 49.4 years and an experience of 26.4 years; allergic reactions - at the age of 47.6±6.3 years and the experience of 25.8±3.7 years. Conclusion. There were identified features in incidence and its structure among doctors and paramedical workers. The basis of the concept of prevention of occupational diseases among health workers should be a system of primary prevention measures to reduce the impact of adverse factors of the working environment and the labour process, maintaining occupational and general health.

Discussion on the evaluation of occupational disease diagnostic criteria

Occupational disease diagnosis standards are an important basis for occupational disease diagnosis, occupational health surveillance, occupational health supervision, occupational disease treatment, occupational disease disability assessment, and handling of occupational disease diagnosis disputes in conjunction with the "Occupational Disease Prevention and Control Law of the People's Republic of China". With the successive promulgation of the "Standardization Law of the People's Republic of China" and the "Administrative Measures on Health Standards", the establishment of a mandatory standard implementation evaluation mechanism has gradually been paid attention to. However, there is still a lack of systematic research on the evaluation of diagnostic criteria for occupational diseases. Therefore, this article combines the current status of the diagnostic standards for occupational diseases in China, and proposes reasonable suggestions on how to carry out the evaluation of the implementation of this type of standard in terms of evaluation methods and content.

Occupational Risk Perception and occupational and work-related diseases prevention

Abstract Background It is estimated 6500 daily deaths by occupational diseases with a high social and economic impact. Several studies show that the perception of occupational risks acts as a precursor to preventive attitudes and behaviors of workers. Nevertheless, attention paid to the perception of occupational risks is scarce and even controversial. This study focuses on a model used by behavioral safety programs associating it with the psychometric paradigm, to understand the worker's risk perception of a Portuguese Health Education and Research Institution (Portugal). Methods This cross-sectional study covered a total of 84 workers. Of these,73% had a very differentiated academic background (doctorate, and post-doctorate degrees). Workers can carry out their activities in more than one work area.60% work in Research, 49% in the Education, 42% in Laboratories and 47,6% in the General and Administrative Services. Risk perception (cognitive and emotional) was assessed using an online questionnaire that also included sociodemographic and occupational information and perception of exposure to occupational hazards. Results 95% of participants reported exposure to at least one occupational risk factor, but only 22% perceived the risk (probability of accidents and illnesses associated with the work performed). There was a positive correlation between the perception of exposure to occupational hazards and risk perception (p &amp;lt; 0,001) and that, the greater the perceived risk, the lower the tolerance to it (p &amp;lt; 0,001).While teaching, research and laboratory work is associated with low perception and high-risk tolerance, individual variables such as gender, age, educational qualifications, and professional category did not influence the perception of risk. Conclusions Understanding how risk is perceived by workers is determinant for the effective occupational risk management. Key messages Occupational risk perception is necessary to prevention of occupational and work-related diseases. Occupational risk perception is determinant for the complementarity of the on-site diagnosis of real work situations and relevant for dynamization of Occupational Health services.

Objective: To grasp the occupational health monitoring of radiation workers in medical institutions across the country, and to discover weak links in the prevention and treatment of occupational radiation diseases. Methods: In 2020 January, according to the monitoring data of the "National Radiation Health Information Platform" (Occupational Radiation Disease and Occupational Health Monitoring Subsystem and Occupational Radiation Disease Reporting Subsystem) , the national occupational health monitoring data from January 1 to December 31, 2019, including the number of radiation workers in medical institutions, occupational health examinations, personal dose monitoring and occupational radiation disease diagnosis, were descriptive analyzed. Results: There were a total of 394436 radiation workers in medical institutions across the country. The number of radiation workers in various provinces was quite different, with a median of 10206, which was positively correlated with the number of permanent residents in each province (r=0.947) . There were 376 personal dose monitoring institutions nationwide, and the personal dose monitoring rate of radiation workers in medical institutions was 96.61% (381045/394436) . There were 419 occupational health inspection institutions for radiation workers across the country, and 269 (64.20%) used software to print physical examination forms. A total of 334455 radiation workers in medical institutions had been subjected to occupational health examinations. The rate of occupational health examinations for radiation workers in medical institutions was 84.79% (334455/394436) . The abnormal rate of chromosomal aberrations in peripheral blood lymphocytes of radiation workers in medical institutions was 0.33% (776/233571) , the detection rate of posterior posterior subcapsular turbidity was 0.63% (2093/334455) , and the abnormality rate of thyroid color ultrasound was 28.49% (14946/52464) . In 2019, a total of 16 cases of occupational radiation diseases were reported. Conclusion: The personal dose monitoring rate and occupational health examination rate of medical radiation workers nationwide are relatively high, but the quality of lymphocyte chromosome aberration analysis, eye lens examination and thyroid color photograph examination needs to be further improved.

Assessment of the influence of pesticides based on glyphosate on the health of agricultural producers

Introduction. The results of a hygienic risk assessment of the use of pesticides based on glyphosate in agricultural production are presented. The study of the pathogenetic mechanisms of action on the body of widely used glyphosate-containing herbicides and the search for markers of health conditions that change under the influence of these drugs are of increasing interest for the early diagnosis of pathological processes and the prevention of occupational and occupational diseases. The aim of this study was to assess the health effects of glyphosate-based pesticides on the health of operators in an agricultural environment. Materials and methods. The clinical material for the study was the plasma and erythrocytes of the peripheral blood of operators in contact with glyphosate-containing pesticides. As a control group, 20 clinically healthy individuals of the same age group, who had no contact with the studied pesticides, were selected. There were assessed leading indices of general clinical and biochemical blood tests and markers of endogenous intoxication and oxidative stress. Results. There were established acceptable risk of exposure to pesticides on workers, subject to compliance with technological regulations and safety requirements. Minor deviations of indicators of general and biochemical blood tests were revealed. A statistically significant increase in the total level of carbonyl derivatives compared to control was obtained among operators who had more substantial contact with glyphosate-containing pesticides. Conclusion. Working conditions when using preparations in the form of aqueous solutions containing glyphosate, using ground-based spraying of steam fields with a consumption rate of 8 l / ha, subject to compliance with regulations and safety measures, comply with hygienic requirements. The established statistically significant changes in the blood parameters of the operators in comparison with the control group indicate the presence of a risk to the health for workers in contact with glyphosate-containing pesticides and indicates the need for additional biochemical studies during periodic medical examinations of agricultural workers for the early detection of deviations in the health state caused by exposure to pesticides, including those containing glyphosate.
