Sharps injuries among healthcare workers in Liberia and Ghana: a cross-sectional survey.

There are little data on sharps injuries among healthcare workers in West Africa despite the region's high rate of hepatitis B and human immunodeficiency virus. The purpose of this study is to investigate healthcare workers' history of sharps injuries in Liberia and Ghana. An electronic cross-sectional survey was conducted among healthcare workers in Liberia and Ghana from February to June 2022. A link to the survey was texted to participants through professional association membership lists, including nursing, midwifery, and physician assistant organizations in both Liberia and Ghana and a physician organization in Ghana only. Five hundred and nine participants reported an average of 1.8 injuries per year in Liberia and 1.1 in Ghana (P ≤ .01); 15.1% of healthcare workers reported three or more injuries in the past year. Liberia had a higher proportion of frequently injured workers (P = .01). Frequently injured workers were evenly distributed across worker types. Workers in this region are vulnerable to sharps injuries. A frequently injured subset of workers likely has distinctive risk factors and would benefit from further investigation and intervention.

[Quantitative analysis of the characteristics and influencing factors of hearing loss among workers exposed to noise in Tianjin].

Objective: To analyze the characteristics of high-frequency average hearing loss in both ears of noise exposed workers in Tianjin in 2020, and quantitatively analyze the influencing factors of high-frequency hearing loss in both ears of workers. Methods: In March 2023, Collect and organize basic information about noise-hazardous enterprises and personal information of workers exposed to noise. Data from the Tianjin Occupational Disease and Health Hazard Factors Information Monitoring System from January 2020 to December 2020, and analyze the impact of basic information of employees, enterprise size, regional distribution, industry category, and economic type on the high-frequency average hearing loss of workers during work. Apply logistic regression to quantitatively analyze the influencing factors of abnormal high-frequency average hearing threshold of noise exposed workers. Results: The size, economic type, industry category, and regional distribution of enterprises, as well as the gender, age, length of service of workers, have an impact on the abnormal high-frequency average hearing threshold of noise exposed workers (χ(2)=733.56、3 497、27、1352.84、1197.62、2570.59、22.30、506.60, P<0.001) . Quantitative analysis using a logistic regression model showed that in the basic information of workers, noise exposed workers were male (OR=2.500, P<0.001) and aged 30-39, 40-49, and 50-59 years (OR=1.33, P<0.001; OR=1.68, P<0.001; OR=1.52, P< 0.001) , with a length of service of 4 to<10 years and≥10 years (OR=1.08, P<0.001; OR=1.615, P<0.001) being the influencing factors for high-frequency hearing loss in both ears of noise exposed workers; In terms of enterprise characteristics, medium-sized, small and micro enterprises (OR=1.12, P<0.001; OR=1.75, P<0.001; OR=2.09, P<0.001) , enterprises located in the fourth district around the city (OR=1.268, P<0.001) , and enterprises with economic types of collective economy, other economy, private economy, Hong Kong, Macao and Taiwan investment, shareholding system, and other industry economies (OR are all >1, P<0.001) are all factors affecting high-frequency hearing loss in noise exposed personnel. Conclusion: Noise is a common occupational hazard factor in Tianjin's enterprises, especially for workers in micro enterprises who face a high risk of hearing abnormalities. Therefore, enterprises need to strengthen the management and intervention of noise operations to prevent the occurrence of hearing loss in workers.

[Occupational hazards of crystalline silicon solar cell manufacturing industry].

However, the production and manufacturing processes of these cells give rise to various occupational hazards at workplace, thus posing health risks to workers. This review provided an overview of production processes of crystalline silicon solar cells, the characteristics of occupational health hazards (productive dust; physical factors, productive toxicant) and proposed occupational protection suggestions.

[Hierarchical fuzzy comprehensive evaluation of prevention and control level of occupational hazards in coal mines].

Objective: To establish an evaluation model for occupational hazard prevention and control levels in coal mines, to explore the combination of Analytic Hierarchy Process (AHP) and fuzzy comprehensive evaluation, to evaluate the overall situation of occupational hazard prevention and control in coal mines. Methods: In November 2021, Collect information of occupational hazards and their prevention and control status in 30 coal mines. AHP model was first constructed for the elements of occupational hazard prevention and control in coal mines. Then, the AHP and fuzzy comprehensive evaluation method was applied to comprehensively evaluate and grade the occupational hazard prevention and control in coal mines, using the principles of maximum membership and weighted average. Results: The hierarchical fuzzy comprehensive evaluation results for typical coal mine were basically consistent with its occupational hazard prevention and control situation. The dust prevention and control situation was good, the noise prevention and control situation is average, the occupational health monitoring situation was good, the occupational health management situation was average, and the overall level of occupational hazard prevention and control was good. Conclusion: The hierarchical fuzzy comprehensive evaluation model for occupational hazard prevention and control levels, combined with the principles of maximum membership and weighted average, can objectively evaluate and reflect the overall situation of occupational hazard prevention and control in coal mines.

Association of occupational physical activity and disability pension in 756,159 Spanish workers: A prospective cohort study with 13 years follow-up.

Recent research from Nordic countries identified occupational physical activity (OPA) as a risk factor for disability pension, but further research accounting for exhaustive analyses in novel populations is warranted. Our objective was to assess the association between OPA and disability pension using administrative data. This prospective registry-based cohort study used data from the Spanish Continuous Working Life Sample (CWLS). Participants were followed up from baseline (January 1, 2006) to first event of disability pension, mortality, or end of follow-up (September 1, 2019). The assessment of OPA was based on registers of economic activity and their correspondence with a validated OPA index. To examine the association between OPA and disability pension, adjusted proportional hazard, and Fine-Gray models using mortality as competing risk were conducted. We retrieved data from 756,159 workers (57.7% men) with an average age of 38.5 years (SD 11.9). During 13.6 years from baseline to the end of follow-up (9,463,041 person-years), 18,191 men (4.2%) and 9631 (3.0%) women received a disability pension. In the fully adjusted model, participants exposed to higher levels of OPA showed higher risk for disability pension in an exposure-response fashion. Men and women exposed to very high OPA showed the highest HR for disability pension (2.31 [95% CI, 2.17 to 2.46] and 1.68 [95% CI, 1.56 to 1.81], respectively. These results warrant preventative measures to address early involuntary exit from the labour market in workers exposed to high physical work demands.

Examining injury trends in parcel delivery drivers in the United States: Challenges and opportunities.

INTRODUCTION: Growth of e-commerce has caused a vast increase in parcel delivery, which raises concern for safety of drivers and other road users as more deliveries take place. METHODS: This project analyzes injury/illness and fatality trends among workers with delivery-related NAICS codes using three major sources of occupational hazard data in the United States: the Survey of Occupational Illnesses and Injuries, the Census of Fatal Occupational Injuries, and the Industrial Tracking Application. Descriptive statistics were employed to illustrate trends over time as well as to highlight opportunities for improved data collection and dissemination. RESULTS: The number of injuries to drivers has risen sharply over the past decade. Some of this increase appears due to growth of this industry, but increasing overall rates suggest the industry is becoming more hazardous. While nonfatal injuries were typically caused by continuous workplace exposures (e.g., repetitive strain, contact with object/equipment), fatalities were almost exclusively caused by transportation incidents. Additionally, crucial aspects of these trends are difficult or impossible to analyze given the current data landscape. CONCLUSIONS: Observed trends reinforce earlier calls for additional scrutiny of working conditions that threaten drivers. Injuries caused by transportation incidents are likely more severe than others and highlight the danger the transportation system poses to drivers and others. Current data collection and dissemination processes offer room to improve in terms of understanding how to prevent future injuries.

Design and testing of a personalized noise monitoring system.

Agricultural workers are more prone to noise-induced hearing loss than are many other workers. Hearing protection device use among agricultural workers is low, but training can increase hearing protection device use. This work proposes a system designed to automatically inform agricultural workers when they were exposed to noises that exceed the National Institute for Occupational Safety and Health (NIOSH) recommended exposure level. The smartphone-based system worn on the arm uses a noise dosimeter to measure noise exposures throughout the day to within ±2 A-weighted decibels of a Class 2 sound level meter. The device collects location and audio data, which are transferred to a server and presented to the worker on a locally hosted website. The website details noise exposure and helps the worker identify where exposure occurred and what specific tasks exceed NIOSH's recommended exposure limit, putting them at higher risk of noise-induced hearing loss. With this understanding, the worker is expected to adopt behavior changes and better hearing protection use at critical places and times. This pilot study evaluates the accuracy of the noise dosimeter and GPS relative to gold-standard instruments. The system was tested on a farm with outputs compared with gold-standard instruments. A-weighted, 1-sec averaged sound pressure levels and position data were collected while users were performing a variety of tasks indoors and outdoors. The smartphone's external noise dosimeter read within ±2 A-weighted decibels of the Class 2 reference dosimeter 59% of the time. The positioning devices had an average error of sub-4 m. While not perfectly matching gold-standard instruments, the device is capable of identifying and collecting information relative to loud noise events that promote noise-induced hearing loss.

Systemic relations among the variables involved in occupational accidents of the nursing team in a psychiatric hospital.

BACKGROUND: The occupational activities carried out in hospital environments pose occupational risks to professionals. In psychiatric hospitals, due to the characteristics of the patients treated, professionals are also subjected to other risks, such as physical aggression. OBJECTIVE: This research aimed to identify the systemic context, highlighting the cause-and-effect relationships that culminate in occupational accidents that occurred with the nursing staff in a psychiatric hospital in Brazil. METHODS: The current study is an applied research and was divided into three stages. First, the collection of data related to the case study was made and accidents were analyzed and occupational hazards were identified. In the second stage, from the collected information, occupational safety indicators were defined. Lastly, in the third stage, the qualitative aspect of System Dynamics was applied to perform the systemic analysis and to identify how the different variables were related. RESULTS: The results showed that physical aggression was the main cause of accidents. Regarding safety indicators, while both the level of use of Personal Protective Equipment (PPE) by professionals and the high level of PPE protection were positive aspects, the level of training of professionals to use PPE was a negative aspect. The Causal Link Diagram (CLD) showed that the perception of risk influenced the level of use of PPE and those organizational measures influenced the accident rate. CONCLUSION: In conclusion, the systemic analysis of the system dynamics can optimize the diagnostic process of occupational accidents in psychiatric hospitals, and especially help to identify the cause and effect among the variables involved.

Risk Perception amongst Petrol Pump Attendants and Analysis of Indiscriminate Siting of Petrol Stations in Enugu Metropolis.

Proliferation and unregulated siting of petrol stations expose petrol pump attendants to occupational hazards. This study assessed knowledge, risk perception, occupational hazards of petrol pump attendants and site-suitability of petrol stations in Enugu metropolis, Nigeria. This was a cross-sectional analytical study of 210 pump attendants from 105 petrol stations spread within the city and highways. A structured pretested, interviewer-administered questionnaire and a check-list were used to collect data. Analyses were done using descriptive and inferential statistics. Mean age of the respondents was 23.55 ± 5.43 with 65.7% being females, three-quarters (75%) had good knowledge, while 64.3% had poor risk perception of occupational hazards. The commonest hazards reported were fuel inhalation (81.0%) (always) and fuel splashes (81.4%) (sometimes). About half (46.7%) of the respondents used protective equipment. Most of petrol stations had functional fire extinguishers (99.0%) and sand buckets (98.1%) while 36.2% had muster points. Forty percent and 76.2% of petrol stations had inadequate residential and road setbacks respectively with private petrol stations and those on streets leading. Poor risk perception of hazards and indiscriminate siting of the petrol stations exposed petrol pump attendants to hazards. Adequate regulation and enforcement of petrol station operating guidelines with regular safety and health training is necessary.

In the production process, these factors are exceeded, and mass occupational disease hazard events occurred among workers. Exposure to wood dust, formaldehyde, terpene, etc., put workers at increased risk of cancer. This article provides a review of this issue in order to provide a scientific basis for the prevention and control of occupational disease hazards in plywood manufacturing.

[Analysis of dust and noise exposure levels in the mining industry from the national surveillance program in 2019].

Objective: To understand the exposure level of dust and noise in the mining industry and provide data support for revising policy for the prevention and control of occupational diseases. Methods: In May 2022, Data was collected through the National Surveillance Program for Occupational Hazards in the Workplace. Descriptive analysis was conducted for dust and noise levels by industry type and enterprise size from 7, 679 enterprises in the mining industry among 29 provincial regions nationwide. Results: The enterprises in the mining industry included in the National Surveillance Program for Occupational Hazards in the Workplace are mainly small and micro, accounting for 47.97% (3684/7679) and 30.00% (230/7679) respectively. The industry is mainly compred of employers in the non-metallic ming and beneficiation industry, accounting for 50.25% (3859/7679). Among the enterprises with silica dust, coal dust, and noise hazards, the proportion of enterprises where total dust concentration and noise intensity exceed the standard is higher than 50%. 30% of the posts are with an exposure level of silica dust, coal dust, and noise that exceeds the standard. The exceedance rate and the median of the time-weighted average concentration of total coal dust among large and medium-sized enterprises are higher than those among small and micro-sized enterprises (P<0.05) . Conclusion: The dust and noise hazards in the mining industry are lower than in the past in China, but more than 25% of workers are still at a high risk of occupational pneumoconiosis and noise deafness. Therefore, intervention and surveillance strategies should be strengthened in the future.

[The facility design and operation effect of control vehicle emissions hazard in test section of automobile assembly workshop].

The hazard of vehicle emissions mainly come from the four wheel positioning, drum test and vehicle emissions test sections in automobile assembly workshop, which can lead to abnormal hemoglobin and hepatic insufficiency in workers. We researched on preventing toxic gases technologies for the vehicle emissions generated by these three sections, designed the ventilation facilities, and then detected and evaluated the operation effect, thereby improving the working environment, ensuring the occupational health of workers, and providing scientific basis for the control of vehicle emissions hazards.

Influence of occupational exposure on hyperuricemia in steelworkers: a nested case-control study.

BACKGROUND: Occupational exposure may be associated with an increased risk of developing hyperuricemia. This study sheds lights on the association between occupational exposure and hyperuricemia in steelworkers. METHOD: A nested case-control study was conducted within a cohort of workers in steel companies to explore the association between occupational exposure and hyperuricemia. The case group consisted of a total of 641 cases of hyperuricemia identified during the study period, while 641 non-hyperuricemia subjects with the same age and gender distribution were randomly selected from the cohort as the control group. RESULTS: The incidence rate of hyperuricemia among workers in the steel company was 17.30%, with an incidence density of 81.32/1,000 person-years. In comparison to the reference group, the risks of developing hyperuricemia for steelworkers undergoing ever shifts, current shifts, heat exposure, and dust exposure were 2.18 times, 1.81 times, 1.58 times and 1.34 times higher respectively. The odds ratios (ORs) and 95% confidence intervals (CIs) were 1.87(1.12-3.13) and 2.02(1.21-3.37) for the cumulative number of days of night work at 0-1,972.80 and ≥ 1,972.80 (days), respectively. Compared to the group with the cumulative heat exposure of 0 (°C/year), the ORs (95% CI) for the risk of developing hyperuricemia in the groups with the cumulative heat exposure of 0-567.83 and ≥ 567.83 (°C/year) were 1.50(1.02-2.22) and 1.64(1.11-2.43), respectively. The OR (95% CI) for the risk of developing hyperuricemia was 1.56(1.05-2.32) at the cumulative dust exposure of ≥ 30.02 (mg/m3/year) compared to that at the cumulative dust exposure of 0 (mg/m3/year). Furthermore, there was a multiplicative interaction between heat exposure and dust exposure in the development of hyperuricemia. CONCLUSION: Shift work, heat, and dust are independent risk factors for the development of hyperuricemia in steelworkers. Additionally, there is a multiplicative interaction between heat exposure and dust exposure in the development of hyperuricemia. Interventions for shift work, heat and dust may help to reduce the incidence rate of hyperuricemia and improve the health of steelworkers.

Risk of Radiation Exposure to Emergency Department Personnel From Portable Radiographs.

BACKGROUND: There are concerns that emergency health care workers are exposed to ionizing radiation as the result of frequent portable radiographs obtained in the emergency department (ED) during active patient care. OBJECTIVE: Our aim was to investigate whether ED staff are exposed to significant radiation due to scatter from portable radiography at a busy trauma center and whether exposure was related to factors such as location or distance. METHODS: This was a prospective cohort study performed during 3 consecutive months in the ED at a large, academic trauma center. Volunteer attendings, nurses, and resident physicians were asked to wear dosimeter badges during their shifts throughout the study period. Twelve stationary dosimeters were placed in selected locations in the ED, particularly in the resuscitation rooms, where most of the portable radiographs were obtained. RESULTS: During the 3-month study period, 1464 portable radiographs were obtained in the resuscitation rooms in the ED, mostly chest and pelvic radiographs. Analysis from stationary dosimeters placed in the ED showed a median of 0.18 mSv (95% CI 0.16-0.22 mSv) for the main resuscitation room and 0 mSv for other critical care patient rooms. Analysis of dosimeters worn by staff showed no measurable radiation exposure (0.00 mSv). CONCLUSIONS: The level of radiation exposure to ED staff found in this study was well below the recommended allowable occupational exposure of 50 mSv/y. Radiation exposure is not a significant occupational hazard in a busy ED level I trauma center. Existing precautions should adequately protect staff from occupational exposure, and use of further protective gear, or the need for individual monitoring using dosimeters, appears unwarranted.

Occupational Hazards to the Joint Replacement Surgeon: How Can Technology Help Prevent Injury?

Occupational hazards pose varying threats to the joint replacement surgeon. Musculoskeletal pain due to the repetitive nature of performing joint arthroplasty is felt daily by most surgeons. The purpose of this paper is to offer a basic introduction and demonstrate the many ways technology utilized during total joint arthroplasty can help mitigate common occupational hazards for the arthroplasty surgeon. This paper guides readers through the evolution and drivers behind technology in joint arthroplasty, describes several technologies currently available, and discusses how certain aspects of this technology may work to improve surgeon and patient outcomes. We review how advanced technologies in arthroplasty may reduce physical and mental demand, improve reproducibility, and decrease complications. The decision to utilize advanced technology in joint arthroplasty is ultimately made on an individual level after careful consideration of available literature.

Occupational hazards, sleep quality and musculoskeletal problems of pregnant workers.

The aim of this study was to identify the relationship between musculoskeletal problems and sleep quality and exposure to occupational hazards in working pregnant women. The study included a total of 142 pregnant women working in various industries. The risk of experiencing musculoskeletal system problems was found to increase with impaired sleep quality (OR interval min =1.132 max =1.303). As the amount of work-related physical damage increased, musculoskeletal complaints increased (OR interval min = 1.228 max = 1.527). Environmental hazards and psychosocial hazards seemed to increase the risk of having musculoskeletal problems (OR interval min = 1.209 max = 1.465, and OR interval min = 1.326 max = 1.547, respectively). Physical, psychosocial and workplace environmental hazards seemed to increase the risk of musculoskeletal complaints in pregnancy. It was also seen that as sleep quality decreased, so musculoskeletal complaints increased.Impact StatementWhat is already known about this subject? Occupational hazards and poor sleep quality can be associated with adverse health outcomes. Pregnant women working in different industries in Turkey may also face work-related hazards. They may also experience pregnancy-related sleep problems. In this context, there is a need to identify occupational hazards and problems related to sleep and to provide protective strategies.What do the results of this study add? The most frequent physical hazard was determined to be a simultaneous bending and rolling movement, the most frequent work environment hazard was noise exposure and the most frequent psychosocial hazard was the lack of a reward system. Physical, work environment and psychosocial hazards were observed to increase the risk of musculoskeletal problems. Moreover, the risk of having musculoskeletal problems increased as sleep quality deteriorated.What are the implications of these findings for clinical practice and/or further research? Training should be planned for working women, including the idea of conception and work-related hazards and protective strategies. It may be possible to provide arrangements related to the workplace by including employers in this training.

Prevalence of Needle Stick and Sharps Injury and Hepatitis B Vaccination among Healthcare Workers in a South-East Nigerian Tertiary Hospital.

BACKGROUND: Daily, HCWs are exposed to needle stick and sharps injury (NSSI) and associated risk of life-threatening infections. AIM: A cross-sectional study was conducted to determine the prevalence of NSSI and HBV vaccination among 341 HCWs at NAUTH, Nnewi. METHODS: Data was collected using a self-administered. questionnaire and interview of key staff. RESULTS: The mean age of participants was 33.4±11.9 years while male: female ratio was 1:1.7. Prevalence of NSSI in the preceding 12 months was 25.5% with doctors (43.0% [34/79]), laboratory scientists (27.5%[14/51]) and nurses (21.8%[17/78]) leading (p=0.014). Noncompliance with standard precaution (SP) and non-display of relevant SP SOPs in prominent places were significantly associated with NSSI (p=0.001). Among those exposed to NSSI, only 33.7% (28/83) consulted a doctor, while 16.9%(14/83) took post-exposure prophylaxis. Two-third (68.8% [190/276]) of respondents correctly cited HBV/HCV as vaccine-preventable blood-borne healthcare-associated infection (HAI) while half (50.9% [161/316]) had received HBV vaccination. Profession (p=0.018), display of SOPs in prominent places (p=0.015), ability to cite HBV/HCV as vaccine-preventable blood-borne HAI (p=0.001), and compliance with SP (p<0.001) were significantly associated with HBV vaccination. Unit heads' responses implied lack of written policy on HBV vaccination, adequate training on NSSI prevention, and HBV vaccination support. CONCLUSION: Among HCWs, NSSI is high but under-reported while HBV vaccination rate is unimpressive. Profession, display of relevant SOPs, and compliance with SP positively affected both NSSI occurrence and HBV vaccination while knowledge about vaccine-preventable blood-borne HAI also influence HBV vaccination status. Written policies on HBV vaccination and NSSI prevention/ management, their communication and enforcement among HCWs, adequate training/retraining, display of SOPs in prominent places, and free HBV vaccination are recommended.

CONTEXTE: Les travailleurs de la santé sont quotidiennement exposés aux blessures par piqûre d'aiguille et par objets tranchants (NSSI) et au risque associé. blessures par aiguilles et objets tranchants (NSSI) et au risque associé d'infections potentiellement mortelles. OBJECTIF: Une étude transversale a été menée pour déterminer la prévalence des blessures par aiguilles et objets tranchants et de la vaccination contre le VHB parmi 341 travailleurs de la santé à NAUTH, Nnewi. MÉTHODES: Les données ont été recueillies à l'aide d'un questionnaire autoadministré et d'un entretien avec un informateur clé. RÉSULTATS: L'âge moyen des participants était de 33,4±11,9 ans et le rapport hommes/femmes était de 1:1. le rapport hommes/femmes était de 1:1,7. La prévalence de l'INSS au cours des 12 mois précédents était de 25,5 %. mois précédents était de 25,5 %, avec des médecins (43,0 % [34/79]), des scientifiques de laboratoire (27,5 % [14/51]) et des professionnels de la santé. (27,5% [14/51]) et les infirmières (21,8% [17/78]) en tête (p=0,014). Le non-complaisance avec la précaution standard (SP) et le non-affichage des PONs pertinentes de la SP dans des endroits bien en vue étaient significativement associés à la NSSI (p=0.001). Parmi les personnes exposées aux MSSN, seuls 33,7 % (28/83) ont consulté un médecin, tandis que 16,9 % (28/83) ont consulté un médecin, tandis que 16,9% (14/83) ont pris une prophylaxie post-exposition. Deux tiers (68,8% [190/276]) des personnes interrogées ont correctement cité le VHB/VHC comme une infection transmissible par le sang et prévenue par un vaccin, tandis que la moitié (50,9% [161/316]) avait été vaccinée contre le VHB. La profession (p=0,018), l'affichage des SOPs dans des dans des endroits bien en vue (p=0,015), la capacité à citer le VHB/ VHC comme une IHA hématogène évitable par la vaccination (p=0,001) et la conformité à la PS (p<0,001) étaient significativement associés à la vaccination contre le VHB. Les réponses des chefs d'unité impliquaient l'absence de politique écrite sur la vaccination contre le VHB, de formation adéquate sur la prévention des INSS et de soutien à la vaccination contre le VHB. CONCLUSION: Parmi les travailleurs de la santé, l'INSS est élevée mais sous-déclarée tandis que le taux de vaccination contre le VHB n'est pas impressionnant. La profession, l'affichage de procédures opératoires normalisées (PON) pertinentes et la conformité à la PS ont eu un effet positif sur l'occurrence des INSS et la vaccination contre le VHB, tandis que les connaissances sur les infections hématogènes évitables par la vaccination influencent également le statut de la vaccination contre le VHB. Les politiques écrites sur la vaccination contre le VHB et la prévention et la gestion des INSS, leur communication et leur application parmi les établissements de soins de santé, une formation et un recyclage adéquats, l'affichage des procédures opérationnelles standard dans des endroits bien en vue, et la vaccination gratuite contre le VHB sont recommandées. MOTS CLÉS: Prévention, risques professionnels, personnel hospitalier, infections transmissibles par le sang, Nnewi.

Incense Burning Indoor Pollution: Impact on the prevalence of prediabetes and Type-2 Diabetes Mellitus.

Objectives: Incense burning is a well-known practice in Asian and Middle Eastern cultures for ceremonial and religious purposes. The excessive use of incense burning has become a critical environmental health concern. The incense sellers are more exposed to incense allied air pollution. This study examines the association between prediabetes and type 2 diabetes mellitus (T2DM) in incense sellers. Methods: This cross-sectional prevalence study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia" during the period July 2019 to January 2020. After medical history and examinations had been performed, a total of 265 non-smoking volunteers male incense sellers were selected. American Diabetes Association (ADA) criteria were followed, people with "HbA1c less than 5.7% were considered normal; HbA1c 5.7%-6.4% were pre-diabetics, and HbA1c > 6.4% were considered people with diabetes". In shops, the incense sellers were exposed to incense-related pollution for 8 hours daily, seven days a week. The mean age for the participants was 25±5.5 years, and body mass index was 19±2.8 (kg/m)2. Results: In incense sellers, the pre-diabetic was 125 (47.2%), and diabetes was 75 (28.3%). However, 65 (24.5 %) incense sellers were without prediabetes and diabetes. There was an increase in HbA1c levels with increasing working exposure to incense shops. Conclusions: The prevalence of pre-diabetic and type-2 diabetes was increased in incense sellers. The prevalence of pre-diabetic and type-2 diabetes was further increased with the increasing working duration of incense sellers. The study findings call for safe practice and avoiding indoor burning incense. It is suggested that well-ventilated areas with proper masks for the workers may reduce the incense-related pollution effects.

The COVID-19 era: How therapists can diminish burnout symptoms through self-care.

COVID-19 is a frightening, stress-inducing, and unchartered territory for all. It is suggested that stress, loneliness, and the emotional toll of the pandemic will result in increased numbers of those who will seek psychological intervention, need support, and guidance on how to cope with a time period that none of us were prepared for. Psychologists, in general, are trained in and know how to help others. They are less effective in taking care of themselves, so that they can be their best in helping others. The article, which aims to heighten clinicians' awareness of the need for self-care, especially now in the post-pandemic era, describes the demanding nature of psychotherapy and the initial resistance by therapists to engage in self-care, and outlines the consequences of neglecting to care for themselves. We covered the demanding nature of psychotherapy and its grinding trajectory, the loneliness and isolation felt by clinicians in private practice, the professional hazards faced by those caring for others, and the creative and insightful ways that mental health practitioners can care for themselves for the good of their clients, their families, and obviously, themselves.

[Analysis of volatile organic components of organic solvents used in Bao'an District of Shenzhen].

Objective: To understand the volatile organic components in the organic solvents used by enterprises in Baoan District, Shenzhen. Methods: From January to December 2020, a total of 541 organic solvent samples used by 86 companies were collected for volatile organic component analysis, and the main volatile components and high-risk occupational hazards in organic solvents used in different industries were analyzed. Results: A total of 201 volatile organic components were detected in 541 organic solvents. The top 5 components detected include xylene (29.76%, 116/541), toluene (21.81%, 118/541), methanol (20.70%, 112/541), n-hexane (14.79%, 80/541) and ethylbenzene (14.23%, 77/541). The detection rates of benzene, trichloroethylene, n-hexane, and 1, 2-dichloroethane, which were high-risk occupational hazards, were 2.40% (13/541), 3.70% (20/541), 14.79% (80/541), and 1.66% (9/541), respectively. The volatile components in organic solvents used in different industries was different. Benzene is more frequently detected in organic solvents used in the printing industry, trichloroethylene was more frequently detected in organic solvents used in the electronics industry, and n-hexane was more commonly found in organic solvents used in the electronics industry, printing and other industries, and 1, 2-dichloroethane has been more frequently detected in organic solvents used in the machinery industry. Conclusion: There are many types of organic solvents used by enterprises in Bao'an District, with complex components and differences in different industries.
