Objectives: Analyze MSDs among workers of the National Electricity Company of Senegal. Methodology: This was a cross-sectional, descriptive and analytical study, carried out from April 2 to May 15, 2022. The INRS TMS questionnaire version 2000 was used. The analysis was carried out with Excel 2016 and R version 4.1.1 software. During the bivariate analysis, the Chi2 test was used. The p was considered significant if it was less than 0.05. Results: The average age of the sample was 42.4 years ± 9.5. The sex ratio (M/F) was 3.16 in favor of men. The prevalence of MSDs was 91%. The average number of MSD locations per affected worker was 3.1. Low back pain (58.8%) and back pain (54.2%) were the most frequently reported MSDs. When working, the sitting position and prolonged standing position were adopted respectively by 57.7% and 39.4% of workers. Break time, work requiring work very quickly, work under deadline, risk of error in work in the event of lack of concentration and the latitude of being able to work at the desired speed had a significant link with occurrence of MSDs (p<0.05). Conclusion: MSDs constitute an occupational health problem within the National Electricity Company of Senegal. This study proves the need to strengthen, on the one hand, awareness, training of workers and on the other hand, the review of the organization and management of personnel.

Objectives: assess the level of knowledge, attitudes and practices of health personnel in the Sangalkam Health District on blood exposure accidents. Methodology: We conducted a cross-sectional, descriptive and analytical study, from April 1, 2023 to May 30, 2023. A standardised, anonymous questionnaire was drawn up and sent to healthcare staff. Results: A total of 60 carers took part in the study, 88.3% of whom were women. Midwives were more represented (31.7%). Hepatitis B vaccination coverage was 69.6%. 31.7% of respondents were aware of the viruses most feared in the event of a blood exposure accident (HIV, HBV and HCV). They claimed to know the principles of universal precaution in 91.5% of cases. The prevalence of blood exposure accidents was 61.7%, i.e. 27% reported. Washing with soapy water was carried out immediately after the BEA in 56.8% of cases. Needles were recapped by 28.3% of respondents. Where there was a risk of splashing of biological fluid, personal protective equipment (gown, mask, goggles) was worn by 23.3% of respondents. Overloading of safety containers was reported in 11.7% of cases. Respondents’ knowledge and attitudes were not significantly related to socio-professional characteristics (p>0.05). Conclusion: Compliance with standard precautions and the use of safety equipment could significantly reduce the risks associated with AES. In addition, awareness-raising and vaccination of healthcare workers against hepatitis B should be encouraged.

Introduction: Psychosocial risks at work are defined as risks to mental, physical and social health created by employment conditions, organizational and relational factors likely to interact with mental functioning, our study had as a general objective to assess the impact of psychosocial factors among workers in the Ministry of Justice in the Republic of Guinea. Method: This was a descriptive cross-sectional epidemiological study lasting 6 months from january 1 to June 30. The study covered all workers in the justice ministry. Results: The distribution of the psychological state of the participants by workstation reveals that the frequency of stress was very high among transplant staff (74.29%) lower (55%) among secretaries and (43.48) among penitentiaries, (34.85%) among administrators. The frequency was very low among socio-educational staff (16.67%) and contract workers (13.04%). Conclusion: Psychosocial risks are frequent in the workplace, particularly in our study population. A good management policy and prevention of RPS must be developed by the various actors involved: the occupational physician in charge of staff health, the governing bodies of the Ministry of Justice as well as the workers.

Introduction: Noise is any sound or set of sounds considered undesirable because they are disturbing or because they are likely to affect health. Continuous exposure to average noise levels of over 85dB may cause several psychophysiological disorders Our study aimed to study the level of noise exposure and the state of hearing protection of workers at Conakry Gbéssia International Airport. Material and methods: This were a descriptive cross-sectional study lasting 6 months from January 13, 2020 to June 13, 2020. It focused on SOGEAC employees at Conakry international airport. Results: our study involved 232 workers at Conakry airport, all exposed to noise. The study population was young with an average age of 34.84 +/- 19.84 and extremes of 18 and 57 years. The workers at Conakry airport who participated in our study were predominantly 72.73% men. The most common symptoms experienced during or after labor were wheezing / buzzing with 83.19%. All Conakry airport employees interviewed are equipped with personal protective equipment (PPE) on an annual basis, but only 36% regularly use such PPE. Conclusion: The absence or improper use of personal protective equipment appears to be the main factor in noise pollution among Sogeac workers However, better communication on the risks associated with noise pollution and the establishment of regular supervision of the correct wearing of PPE would improve the protection and safety of workers.

Objective: To assess the level of knowledge on the risks and prevention methods of pump attendants. Material and methods: This were a descriptive cross-sectional study lasting 06 months from 01 March to 30 August 2019 Our variables were clinical (occupational risk and means of prevention) and epidemiological (age - gender - marital status - level of education - length of service). Results: In our study, the average age of pump attendants was 32.06 years. The most represented age group was 28 to 37 years old. The means of prevention mentioned by the pump attendants were dominated by the correct wearing of clothing, i.e. 98% followed by the wearing of boots and masks respectively 95% and 47%. The most dominant risk factor was intoxication with 123 cases or a rate of 61.5% followed by fires with 116 cases or a rate of 58%. Conclusion: The pump attendants of gasoline service stations have insufficient knowledge of the risks and prevention methods related to hydrocarbons. This prevention essentially involves training, information, education and communication actions on the risks associated with hydrocarbons.

Introduction: Burnout is a common syndrome among medical students The objective of this study was to assess the prevalence of burnout among students in the 7th year of the Faculty of Technical and Health Sciences of the University of Conakry.
