Occupational Hearing Loss

Introduction. Agricultural workers belong to the cohort of increased risk of developing occupational hearing loss (OHL). When studying occupational sensorineural hearing loss (SHL), researchers usually limit themselves to stating its share in the structure of occupational diseases without a comprehensive analysis of the initiating occupational factors and the relationship between the development of the disease with the age of employees and occupational experience. Materials and methods. The study is based on data on working conditions and occupational diseases by type of economic activity “Agriculture, forestry, hunting, fishing and fish farming” in the Saratov region from 2000 to 2019. The assessment of the factors of working conditions was carried out using the methods of the current hygienic classification. Generally accepted indicators were used to characterize occupational diseases. Linear regression analysis and polynomial equations were used to describe trend models of the prevalence of occupational diseases. Calculations and data analysis was carried out based on Microsoft Excel and Statistica application software packages. Results. Occupational hearing loss occupied the fourth rank after dorsopathies, vibration disease and chronic brucellosis in the nosological structure of accumulated occupational diseases. The level of primary incidence of SHL was in the range of 0.11 - 0.71 per 10000 workers. All cases of OHL were detected in agricultural machine operators whose harmful working conditions were characterized by a synergy of industrial noise (classes 3.1-3.3) and general vibration (classes 2-3.2). For the most part, SHL was diagnosed in workers aged 50 to 60 years with a work experience of 8 to 42 years in the profession and acted as the second or third concomitant occupational disease associated with dorsopathy, vibration disease or bronchopulmonary diseases. Conclusion. The absence of a statistically significant decrease in the level of PPP among agricultural workers during the observation period indicates the insufficient effectiveness of preventive measures to minimise occupational noise exposure.

AbstractAgricultural workers who have concurrent exposure to pesticides and noise are at increased risk of hearing loss. We recruited 163 Thai conventional and 172 organic farmers to answer our questionnaires about personal demographics, agricultural activities, and pesticide and agricultural machinery use. This information was used to calculate the years of conventional (pesticide use) farming and the years of agricultural noise exposure, and to estimate semiquantitative metrics for pesticide exposure (cumulative intensity score-years) and cumulative noise exposure (dB(A)-years) for each conventional farmer. All participants underwent pure tone audiometric testing. The mean hearing threshold in the low-frequency band (0.5–2 kHz) and high-frequency band (3–6 kHz) were used for analysis. Years involved in conventional farming and years using agricultural machinery were associated with an increase in the average hearing threshold for the high-frequency band after controlling for age, ever exposed to industrial noise and cigarette smoking. The highest category of cumulative insecticide exposure (score-years), cumulative organophosphates exposure (score-years) and cumulative noise exposure (dB(A)-years) were also associated with an increased high-frequency band hearing threshold among conventional farmers. Results from the full cohort and the subcohort of conventional farmers support each other and the hypothesis that pesticide and noise have an additive effect on hearing, since no model interactions were significant.

Introduction. There are currently several works in the scientific literature devoted to studying the influence of working conditions on mobile agricultural machinery on the occupational morbidity of workers on the example of individual regions. Still, Russian Federation did not conduct such studies before. The study aims to analyze working conditions and current trends in the formation of occupational pathology when working on mobile agricultural machinery in the Russian Federation. Materials and methods. The paper uses the results of long-term sanitary-hygienic and ergonomic studies of working conditions when working on mobile agricultural machinery and data on the level of occupational morbidity (PZ) of farmworkers of the Russian Federation in 2011-2017. Results. Microclimatic discomfort, dustiness and gas contamination of the working area air, industrial noise, general and local vibration, physical overload, forming harmful operating conditions (classes 3.2-3.4), occupational risk categories from medium to very high characterize working on mobile agriculture machinery. From 2011 to 2017, researchers have identified 960 agricultural machine operators with 1052 occupational diseases in the Russian Federation, formed mainly under the influence of physical factors and physical overloads. In the nosological structure of occupational diseases (OD), the first place is occupied by vibration disease (VD), the second by radiculopathy (RP), and the third by sensorineural hearing loss. Researchers characterize the current trends in the nosological structure by a significant increase in the prevalence of radiculopathy against the background of a decrease in diagnosis cases of vibration disease. Conclusions. Working conditions when working on mobile agricultural machinery remain harmful and pose a high risk of developing occupational radiculopathy, vibration disease and sensorineural hearing loss. It should be taken into account when developing measures to prevent occupational pathology for agricultural machine operators.

Introduction. Due to the impact of adverse working conditions and climate, workers in coal-mining enterprises in the Arctic are at increased risk of occupational diseases (OD).The aim of the study was to study the working conditions, causes, structure and prevalence of occupational diseases in miners of coal mines in the Arctic.Materials and methods. Th e data of social and hygienic monitoring “Working conditions and occupational morbidity” of the population of Vorkuta and Chukotka Autonomous District in 2007–2017 are studied.Results. It was established that in 2007–2017 years, 2,296 ODs were diagnosed for the first time in 1851 coal mines, mainly in the drifters, clearing face miners, repairmen and machinists of mining excavating machines. Most often, the ODs occurred when exposed to the severity of labor, fibrogenic aerosols and hand-arm vibration. The development of professional pathology in 98% of cases was due to design flaws of machines and mechanisms, as well as imperfections of workplaces and technological processes. Diseases of the musculoskeletal system (36.2%), respiratory organs (28.9%) and nervous system (22.5%) prevailed in the structure of professional pathology of miners of coal mines. Among the three most common nosological forms of OD were radiculopathy (32.1%), chronic bronchitis (27.7%) and mono-polyneuropathy (15.4%). In 2017, coal miners in the Arctic had a professional morbidity rate of 2.82 times higher than the national rates for coal mining.Conclusions. To preserve the health of miners of coal mining enterprises, technical measures to improve working conditions and medical interventions aimed at increasing the body’s resistance to the effects of harmful production and climatic factors are necessary.

Occupational Hearing Loss

Exposure to industrial noise and the resulting effect of occupational hearing loss is a common problem in nearly all industries. This chapter describes industrial noise exposure, its assessment, and hearing disorders that result from overexposure to noise. Beginning with the properties of sound, noise-induced hearing loss and other effects of noise exposure are discussed. The impact of hearing disorders and the influence of other factors on hearing loss are described. Typically, noise-induced hearing loss develops slowly, and usually goes unnoticed until a significant impairment has occurred. Fortunately, occupational hearing loss is nearly always preventable. Therefore, this chapter gives particular attention to recommendations for measures to prevent occupational hearing loss such as engineering noise controls and hearing protection devices.

Abstract: Working conditions at metallurgical enterprises are characterized by the impact of a complex of harmful production factors that do not correspond to the normalized levels, which causes the risk of developing professional and professionally conditioned pathology. Trained workers who are exposed for a long time to industrial noise that exceeds the permissible values by 10 dB or more are considered as a risk group for the development of aural (sensorineural hearing loss, SHT) and extraaural (high blood pressure, HBP) pathology. Hearing loss is an important medical and social problem, as it turns into a cognitive dissonance and a violation of verbal communication for the employee. Working conditions at one of the modern metallurgical plants were evaluated according to the data of sanitary and hygienic characteristics of working conditions. The study of the prevalence of SHT and HBP was carried out based on the materials of a medical examination and a questionnaire survey of workers (n=73, male, aged 36-75 years (57.32±0.89), with work experience of 8-58 years (34.29±1.16)). To assess the joint influence of age and seniority, an original scoring system was used, which allowed us to distinguish 3 observation groups. The severity of SHT and HBP was also assessed in points. The study showed a significant increase in the prevalence and severity of hearing loss and HBP with an increase in the duration of exposure and the age of employees. The presence of a close relationship between the analyzed pathology and working conditions is illustrated by the value of the odds ratio in groups 1-3 (ORSHT = 3.75-4.71; ORHBP = 2.0-5.0). Thus, the studied professional group of trained qualified metallurgists needs to develop health-improving measures to preserve labor longevity.

Exposure Levels

Current legislation and threshold limits for occupational noise exposure may not sufficiently account for higher vulnerability of the foetus. We conducted a systematic literature review and identified 20 relevant studies of prenatal noise exposure levels and health. Maternal tissues attenuate industrial noise by about 30 dB. The foetus responds the earliest to noise exposure from the 19th week of gestational age. There is some evidence of an increased risk of hearing loss at prenatal noise levels≥85 dBA (8 hour average) and little evidence at lower levels. Increased risks for preterm birth, small-for-gestational-age and congenital malformations are seen as single study findings at levels≥90 dBA. There is little evidence for how noise exposure may increase the risk of extra-auditive effects in the foetus. Methodological shortcomings and the scarce number of studies limit the conclusions that can be drawn. Still, we recommend pregnant women avoid working at noise levels≥85 dBA.

Abstract This study aimed to explore the association of several single nucleotide polymorphisms (SNPs) within the AKT2 gene and noise-induced hearing loss (NIHL) susceptibility and explore the potential mechanism underlying NIHL. Three SNPs (rs2304186, rs41275750 and rs76524493) were genotyped in a Chinese population which consists of 690 NIHL patients and 650 normal hearing controls. Bioinformatic analysis was conducted to predict the potential miRNA-binding site of SNPs. Cell transfection and dual-luciferase reporter assay were performed to investigate the potential molecular mechanism of SNPs involved in NIHL. The results revealed rs2304186 GT genotype (OR = 1.41; 95% CI = 1.09–1.83) and TT genotype (OR = 1.51; 95% CI = 1.08–2.10) imparted increased risk of NIHL, and the increased risk could also be found in a dominant model (OR = 1.44; 95% CI = 1.12–1.84). The stratification analysis showed that rs2304186 GT/TT conferred a higher risk for NIHL, especially in subgroups of male, age (35–45 and > 45 years), noise exposure time (> 16 years), and noise exposure level (≤ 85 and ≥ 92 dB), compared with GG genotype. In addition, the haplotype TCCTACT (rs2304186-rs41275750-rs76524493) was associated with NIHL risk (OR = 1.19; 95% CI = 1.02–1.40). Rs2304186 G allele combined with hsa-miR-625-5p mimics could significantly decrease the luciferase activity compared with T allele, indicating rs2304186 altered the binding affinity of hsa-miR-625-5p to SNP rs2304186 mutation region, thus directly targeting AKT2. In conclusion, our study provides evidence for the first time that SNP rs2304186 of AKT2 3′UTR affects NIHL susceptibility by affecting the binding affinity of has-miR-625-5p in an allele-specific manner and it may act as a potential biomarker of NIHL susceptibility.

AIM: To investigate the impact of tinnitus on professional musicians in the UK. BACKGROUND: Tinnitus is the experience of sound when an external source is absent, primarily associated with the ageing process, hearing loss, and noise exposure. Amongst populations exposed to industrial noise, noise exposure and noise-induced hearing loss (NIHL) have been found to be the factors most associated with tinnitus. The risk of NIHL amongst professional musicians is greater than that amongst the general population, meaning they may be at increased risk of tinnitus. METHODS: Seventy-four professional musicians completed an online survey involving closed and open-ended questions, and completed the Tinnitus fuctional Index (TFI) questionnaire. Descriptive statistics and thematic analysis of open-ended qualitative responses were used to analyse the data. RESULTS: Three themes were generated from the analysis of the responses to the open-ended questions. These themes were: (1) the impact of tinnitus on the lives of professional musicians, (2) professional musician experience of tinnitus services, support, and hearing health and safety, and (3) the support professional musicians want. The mean global TFI score for professional musicians was 39.05, interpreted as tinnitus being a moderate problem. Comparisons with general population data revealed lower TFI scores for the TFI subscales of ‘sense of control’ and ‘intrusiveness’ for professional musicians and higher for auditory difficulties associated with tinnitus amongst professional musicians. CONCLUSION: Tinnitus can negatively impact on professional musicians’ lives. There is a need for bespoke self-help groups, awareness raising, and education to prevent tinnitus and promote hearing health among musicians.

Special Assessment

Currently in healthcare of the Russian Federation created a system of measures to combat the harmful effects of industrial noise on workers. However, the level of specific and nonspecific morbidity rates the effect of industrial noise is not reduced, and the incidence of occupational diseases tends to increase. This is due to several reasons, including a large number of sources of noise, not enough high quality of medical examinations, lack of and low effectiveness of means of individual protection from noise and others. Noise is one of the leading places among the harmful physical factors in the Armed forces of the Russian Federation. Features noise resulting from the operation of military equipment and armament is its high intensity, intermittent nature, the presence in the spectrum of low and infrasonic frequencies. Noise exposure leads to the development of diseases, primarily of the organ of hearing, increase in total morbidity and the reduction of military-professional health. In the normative documents of the military medical service the noise is not identified as a harmful factor leading to the development of occupational diseases that were not fully developed the issues of professional selection and medical examination of noise pathology. System noise control should be comprehensive and include organizational and technical measures, special assessment of working conditions, monitoring of noise sources, the presence and correct application of means of protection against noise professional selection, clinical monitoring, medical examination, treatment and preventive measures. Existing in the Armed forces of the Russian Federation the system of measures for the fight against harmful impact of noise on military personnel requires revision in accordance with the existing state legislative framework.
