Introduction: Occupational risks are common among workers in various industries, including brewing companies. Employees in this sector are frequently exposed to high noise levels caused by machinery vibrations and operational activities. Prolonged exposure to such noise may result in significant hearing issues. This study aimed to assess the prevalence of hearing disorders among brewery workers and explore their association with various risk factors. Data was collected during routine health evaluations at an inter-company occupational health center. Materials and Methods: A cross-sectional descriptive study was conducted based on medical and audiometric records of brewery employees. A non-exhaustive sample of workers was selected. Clinical data were extracted from consultation forms, while audiometric information was gathered by analyzing workers' audiogram curves. Data entry was performed using Epi-Info version 7.2.2.6, and statistical analysis was conducted using IBM SPSS version 2.3. Results: The study involved 169 employees, mostly male (98.2%), with an average age of 51 years (±10.12) and an average length of service of 10 years (±6.88). Hearing loss greater than 20 dB in the worse ear was observed in 21.3% of participants. The minimum recorded hearing loss was 2.5 dB, the maximum 51.3 dB, and the mean loss was 20 dB. Audiometric analysis showed that: 30.2% of the audiograms were normal or near-normal; 34.9% had abnormal patterns suggesting noise exposure; 25.4% had abnormal curves not indicative of noise exposure; 9.5% had ambiguous patterns. No statistically significant associations were found between average hearing loss and most risk factors, except for age (Likelihood ratio = 15.014; df = 4; p = 0.005) and job seniority (Likelihood ratio = 9.164; df = 3; p = 0.027). Conclusion: The findings highlight a notable prevalence of hearing impairment among brewery workers, with age and seniority being significant associated factors. These results underscore the need for more targeted investigations and prompt implementation of preventive strategies to protect hearing health in this occupational setting.

The hematologic disorders induced by inhalation of the fume or the vapor and pollutant gases emanating from the foundry in the industrial and mining sectors are not ignored in the literature and were the subject of this research. Results of the 69 old hard-working subjects from 18 to 65 years which took part. An emanating group of the 23 operators founders exposed to the smoke of the metallurgical furnace and another 46 workers drawn from the personnel looking after nonexposed with metallurgical smoke. The samples of blood were taken and subjected to a complete hematologic analysis. After two group (1) case for two (2) witnesses; the results showed that the rates of haemoglobin (Hb) were significantly reduced at the subjects exposed to the smoke of the metallurgical foundry with an average rate of haemoglobin decreased and lower than the normal (12,5mg% ± 2,0). The founders thus developed 13 times more anaemia than the group controls (C) with a GOLD = 13,45; one p-been worth < to 0,00 is (p = 0,00) and one IC = [3,81; 47,60]. The study revealed that the numeration of red globule or érythrocytaire differs between the two groups, with an erythrocytic average = [4,45 ± 0,95]. This research also highlights that according to level of exposure, that there is a relation amount-effect meaning that the more significant the exposure is, the more anaemia is present with a p = 0,00, a GOLD = 13,46; IC = [4,20; 42,22]. The study observes that a proportion of 43% of the founders carry EAR not-adapted. These results indicate that the emanations of the metallurgical smoke of the foundry are toxic for the man and involve a reduction of the hematologic indices which, with a prolonged exposure could be harmful and fatal for the exposed workers.

Our investigation took place in the Hyper Psaro business enterprise as of november 2024 including a MASLACH-MBI Burnout Inventory Test Questionnaire comprising 22 questions with assertions: Never, A few times a year, once per month; A few times a month, once a week, A few times a week, every day; with a score of: 0; 1, 2, 3,4,5 and 6 which allowed us to have these results. This data collection took place between. The questionnaire was given to 18 workers selected at random; but 10 workers responded to this; whose data was encoded in Excel 2016 and analyzed in Epi.info 7. Our results concerned 10 workers including 3 women and 7 men from the company mentioned above who revealed professional burnout with a score of 42, and depersonalization with a score of 7, and in order to achieve professional achievement with a score of 42; including the graphics below. There is a high burnout score SEP 42, i.e. Burnout is high. Workers have moderate depersonalization because their score is SD 7, that is, the Burnout is moderate. Workers have a high completion score of SDP 42, that is, burnout is high. Based on its results, we concluded that workers in the commercial sector can easily develop burnout syndrome, due to the high stress in the workplace. And in our midst, the commercial sector is mostly run by expatriates who do not consider the psychological component of workers. An in-depth study could be considered in this sector to propose preventive measures.

Accidents at work as a result of deplorable conditions of safety and health at work in particular, the lack of wearing protective equipment are responsible for great suffering, significant losses for employees and their families, employers and social security funds. In addition to the knowledge of the factors explaining occupational risks and the requirements for wearing protective equipment, the world of work will enable the world of work to achieve decent work. The general objective is to improve the prevalence of injuries and their location among injured workers in the formal sector of Haut-Katanga in order to promote the health and well-being of the population of the Democratic Republic of Congo in general and that of Haut-Katanga in particular. Methods: This is a multicenter historical cohort study including all workers in the formal sector in the province of Haut-Katanga victims of accidents at work registered at the National Social Security Fund and in a mining company in the city of Lubumbashi in the province of Haut-Katanga. Results: During this first phase (2010 to 2017), 510 occupational accident files were recorded. The highest accident rate was recorded in 2012. Males account for 93.10%. The bride and groom were the most injured, accounting for nearly 91.72%. The seniority bracket ranging from 1 to 10 years was the most rugged bracket with 63.12%. The primary sector is the most rugged sector with 70.8% of which miners represent 51.5%. Workers with a primary education level are the most injured with 83%. The multivariate analysis shows that workers in the primary sector are the most injured as well as those with a seniority of less than 7 years. Subjects who had head injuries had a better cure rate. During the second phase, the study conducted in a mining company showed that out of a total of 338 workers, 14 cases of occupational accidents were recorded. 95.1% of the victims had a primary education. During this study, wounds account for a significant proportion (37.08%). Among the various injuries recorded (20.12%), those of the chest are the basis of deaths. Involvement of the limbs (lower left limb 22.09%, lower right limb 19.53%, right upper limb with 16.77%, left upper limb with 11.64%), head with 18.15% and trunk with 11.24%. As for the nature of the lesions, wounds account for a significant proportion (37.08%).

Introduction: Occupational risks resulting from deplorable safety and health conditions at work are responsible for major consequences recorded in the families of the injured, for employees as well as for social security funds. Knowledge of the psychosocial factors that may give rise to occupational risks will enable the world of work to develop a coherent occupational safety and health program and to give concrete expression to the concept of decent work.The objective of this research is to study the impact of psychosocial factors in the occurrence of occupational risks in a mining company in the formal sector in the province of Haut-Katanga.Methodology: Our exploratory descriptive study was in a mining company in Haut-Katanga Province in the Democratic Republic of Congo.-The reference population is made up of the workers of this same mining company in Haut-Katanga. These workers were divided into three sectors: mining, mineral processing and administration (support sector).-A stratified random sampling of 338 workers was carried out. The Karasek questionnaire was used for data collection.Results: Our study conducted in a mining company showed that out of a total of 338 workers.During this study, karasek’s questionnaire administered to the 338 workers showed that 258 workers were classified and 80 were not. The addition of addictive behaviors such as alcohol and tobacco consumption showed « low social support » in 83% of those classified, 84.6% had a seniority of at least 5 years and 83.1% were assigned to mining operations.A « low decision-making latitude » was perceived by 91.8% of the classified. Of this group, 89.9% had a seniority of at least 5 years and 97.3% worked in the mining operations sector. A strong psychological demand is reported by 84.8% of classified workers. Of this group, 84% had a seniority of at least 5 years and 86.8% were assigned to the mining operations sectors. The perception of low decision-making latitude was influenced by professional status and industry. Classified workers reported low latitude 2.5 times more than their unclassified counterparts.Conclusion: Psychosocial factors are a reality in our professional environment and therefore responsible for occupational risks.The control and evaluation of psychosocial factors make it possible to prevent the occurrence of occupational risks likely to cause bodily injury and socio-economic harm at different levels.

Introduction: The teaching profession in general is among the professions that impose many mental, physical, psychological and social constraints. Therefore, his environment is supposed to offer him a serene environment in order to allow him to control his health and avoid situations likely to lead to certain circumstances of many dysfunctions whose consequences deteriorate the working conditions of teachers and moreover his health. Nowadays, education is a major asset of essential societal development and as a result, the teaching profession is considered to be a job at high risk of stress, psychological risks following direct and constant contact with learners or even potentially a source of disrespectful behavior and verbal aggression, physiques etc. able to develop strong feelings of inferiority and personal failure if teachers are continually confronted with these types of stress and conflict situations that challenge their professional status, feeling attacked in their work and professional identity, and also a source of burnout. It is counted among the jobs with a significant level of social interactions such as health and social services. Objective: To determine the generating and moderating factors of occupational stress in teachers as well as the profile of blood pressure in this population. Methodology: This was a nested case-control study, conducted in the city-province of Kinshasa from October 2018 to June 2019, in six schools in the primary and secondary sectors. Two hundred and one (201) teachers participated in the study, with the M/F ratio being 2: 1. We administered the Karasek-Siegrist Occupational Stress and Effort/Reward Questionnaire as a first step. Then, after initial measurement of blood pressure by ourselves, we subjected the participants to a self-measurement of their blood pressure, after training according to the recommendations of the French Society of High Blood Pressure. We analyzed by Chi-carré de Kruss-Wallis on the IBPM-SPSS version 20 software, the results by comparing stressed teachers (cases) and controls (relaxed, active and passive subjects).Results: We found 40% of the stressed subjects that we compared to the control groups consisting of 12% of relaxed subjects, 25% of active subjects and 23% of passive subjects. Out of a total of 201 teachers, 20% had an increase in the initial BP ≥ 140/90 mmHg according to the reference values of the classification of the WHO and the European Society of Hypertension.
