Prevalence of injury and utilization of personal protective equipment among building construction workers and associated factors in Bale and West Arsi Zones, southeast Ethiopia 2022.

The building construction industry is well known for being one of the most dangerous industries worldwide. Statistics show it is one of the most dangerous occupations in the world. The aim of this study is to assess the prevalence of injury, personal protective equipment usage among building construction workers, and associated factors in Southeast Ethiopia. Institutional-based cross-sectional study was done among 406 selected construction workers in Southeast Ethiopia. Study participants were selected randomly. Data were collected by using a structured questionnaire. Descriptive statistics was used to summarize study variables. Binary logistic regression was utilized to investigate factors associated with injury among study participants. Accordingly, adjusted odds ratio along its 95% confidence interval were calculated and a p value of <0.05 was used to declare statistical significance. Generalized linear models were utilized to investigate factors associated with the use of personal protective equipment. Accordingly, an adjusted odds ratio with a 95% confidence interval was determined and a p value of <0.05 was used as a level to declare a significant statistical association. In this research 406 building construction workers were interviewed and 393 participants gave complete responses, yielding a 96.8% response rate. Of all participants included in this study, 27 (6.8%) drink alcohol and 26 (6.6%) chew khats. Uses of personal protective equipment among study participants was 133 (33.3%, with a 95% confidence interval of 28.3% to 37.7%). Of 393 participants in this study, 213 (54.2%) of them sustained at least one building work-related injury in the last year. The commonest type of injury that occurred among this population was abrasion 43.3% followed by muscular pain (13%). Not having orientation about personal protective equipment, without safety training, didn't use personal protective equipment, and rural residence were factors significantly associated with injury among building construction workers. Residence, age, monthly income, service year, orientation about personal protective equipment, safety training, and start using personal protective equipment immediately after the job offers were significantly associated with the uses of personal protective equipment by participants of this study. In general, this study has identified a relatively high prevalence of injury and low use of personal protective equipment in the study subjects and associated factors.

The development of occupational safety and health science in the work environment can be seen with the development of advanced science and technology as well as the emergence of new innovations in the work environment and encouraging companies to improve the knowledge and skills of their human resources. The purpose of this study is to determine the Influence of Occupational Safety and Health Education (K3) on the Behavior of Using Personal Protective Equipment at the Special UPTD of Haji Medan Hospital. This research includes quasi-experimental research. This study uses a one group pretest and pottest design. The population in this study is emergency room nurses at the Special UPTD of Haji Medan Hospital which totals 50 nurses in June-August 2024. The sampling technique in this study is total sampling. The measuring tool in this study uses a univariate and bivariate distribution of non-parametric data with the Wilcoxon test. The results of the Wilcoxon statistical test of both knowledge and attitude obtained a P-value of 0.000. This means that at alpha 5% there is a significant difference in median score between before and after counseling. Meanwhile, in the aspect of action, there was an increase in the number of PPE users between before and after counseling. Because the results of Asymp.Sig of knowledge, attitudes and actions are less than 0.05, H0 is rejected so that there is an influence of occupational health and safety counseling (K3) on the behavior of using PPE. In conclusion, there is an influence of Occupational Safety and Health Counseling (K3) on the behavior of using personal protective equipment at the Special UPTD of Haji Medan Hospital. The suggestions are expected to increase the frequency of counseling and provide information on the importance of using personal protective equipment in the workplace, provide strict sanctions against nurses who do not use personal protective equipment at work, increase the frequency.

Solvolysis and oxidative liquefaction of the end-of-life composite wastes as an element of the circular economy assumptions

In pursuit of sustainable development, recycling composite waste is a crucial challenge as well as an opportunity to support the progress towards eco-friendly materials management and circular economy practices. The current study brings together two modern recycling techniques solvolysis and oxidative liquefaction to recycle five types of composite waste materials including wind turbine blades (WTBs), composite pipes, personal protective equipment (PPEs) used in the medical sector, photovoltaic (PV) panels and municipal solid waste (MSW). Following a well-structured experimental design for each type of waste the solvolysis was performed at a temperature range of 100–190 °C, process time within the range of 1–3 h, and catalyst (TBD) concentration within the range of 0.015–0.025 mol, end with ethylene glycol and 1-methyl-2-pyrrolidinone in a 1:1 M ratio, while depending on the material evaluated, the oxidative liquefaction process was conducted at temperatures between 250 and 350 °C for WTB and between 200 and 300 °C for PPE, MSW, and PV. Oxidant concentrations, reaction time and pressure (15–45%, 30–90 min, 20–40 bar for WTBs, 30–60%, 45 min, 30 bar for remaining waste types) were studied in addition to highly variant waste-to-liquid ratio from 5 to 25% for WTB, 3–7% for PPE and MSW, and 12.5–37.5 for PV. Prior to experimental investigation, surface morphologies and chemical studies of the waste material were performed by scanning electron microscope (SEM) and Fourier transform infrared FT-IR spectroscopy, while after experimentation total polymer degradation (TPD) was calculated and liquid products were analysed through gas chromatography with flame ionisation detection (GC-FID). Following the solvolysis, 50–60% TPD was obtained, allowing for the recovery of glass fibres (GF) with average lengths of 50–60 mm and a maximum length of 650 mm. This allowed for the recovery of GFs with average lengths of 50–60 mm and a maximum length of 650 mm. In the case of oxidative liquefaction, total polymer degradation of 72–100%, 52–100% and 55–100% was achieved, depending on the investigated waste, i.e. WTB, PPE and MSW, respectively. The yield of oxygenated chemical compounds depended upon the types and composition of waste, but acetic acid was the main acid while WTB, PPE, and MSW, the liquid samples contained phenol also. Involved chemistry and possible degradation pathways of complex composite wastes are discussed in detail to enhance the recycling process and material recovery.

Active-type piezoelectric smart textiles with antifouling performance for pathogenic control

Recently, an investigation into preventive measures for coronavirus disease 2019 (COVID-19) has garnered considerable attention. Consequently, strategies for the proactive prevention of viral pathogens have also attracted significant interest in the field of wearable devices and electronic textiles research, particularly due to their potential applications in personal protective equipment. In this study, we introduce smart textiles designed with optimized piezoelectric devices that exhibit antifouling performance against microorganisms and actively inactivate viruses. These active-type smart textiles, which incorporate advanced lead zirconate titanate (PZT) ceramics, a stretchable interconnector array, and polymeric fabric, demonstrate effective antifouling capabilities, detaching approximately 90% of Escherichia coli and 75% of SARS-CoV-2. Furthermore, they inactivate viruses, releasing ~26.8 ng of N protein from ruptured SARS-CoV-2, using ultrasonic waves within the wearable platform. Experimental results show that piezoelectric smart textiles significantly reduce the spread of COVID-19 by leveraging the electrical and acoustic properties of PZT ceramics.

Self-Powered Handwritten Letter Recognition Based on a Masked Triboelectric Nanogenerator for Intelligent Personal Protective Equipment.

As one of the most important ways of human-machine interfaces, the touchpad has excellent input convenience. Input devices for extreme environments require simpler structures and diverse inputs to ensure information inputs. This paper proposed a self-powered flexible input panel with single-channel output for the input recognition of all 26 letters, and a paper mask was implemented to cover the triboelectric nanogenerator (TENG) board and obtain more complicated electrical signal features. Based on the change of the triboelectric output of the mask, neural network models with different combinations of layers were designed and optimized, and the highest recognition rate of 88.7% for all letters and 100% recognition accuracy for some letters were achieved among the five testers. For letters with low recognition rates, a specific writing specification was further proposed to improve the accuracy of model recognition. These results facilitate the application of the proposed input panel as a flexible wearable device and personal protective equipment for extreme environments including chemical, biological, radiological, nuclear (CBRN) scenarios or aerospace.

Predictors of seropositivity to SARS-CoV-2 among employees at a large urban medical center

BackgroundBefore SARS-CoV-2 vaccination availability, medical center employees were at high risk of COVID-19. However, risk factors for SARS-CoV-2 infection in medical center employees, both healthcare and non-healthcare workers, are poorly understood.MethodsFrom September-December 2020, free IgG antibody testing was offered to all employees at a large urban medical center. Participants were asked to complete a questionnaire on work and non-work related risk factors for COVID-19 infection.ResultsSARS-CoV-2 seropositivity was found in 4.7%. Seropositivity was associated with close contact with COVID-19 cases with or without the use of adequate personal protective equipment (PPE), (OR 3.1 [95% CI 1.4–6.9] and OR 4.7 [95% CI 2.0–11.0] respectively), never wearing a mask outside of work (OR 10.1 [95% CI 1.9–57]), and Native Hawaiian/Pacific Islander race (OR 6.3 95% CI (1.6–25)].ConclusionsAmong workers in a large urban medical center, SARS-CoV-2 seropositivity was associated with work-related COVID-19 close contacts and low mask use outside of work, suggesting that non-workplace close contacts are also relevant routes of COVID-19 spread among healthcare workers.

Measurement and health risks assessment of BTEX compounds exposure in beauty Lahijan City salons

The presence of BTEX (Benzene, Toluene, Ethylbenzene, and Xylene) compounds in beauty salons has raised concerns about potential health risks. This study aimed to measure the levels of BTEX compounds in the air of beauty salons in Lahijan, Iran and assess the associated health risks. Air samples were collected from 15 beauty salons, and the concentrations of BTEX compounds were measured according to 1501 NIOSH standard method. The results showed that the mean concentrations of benzene (20.62 µg/m3), toluene (18.3 µg/m3), ethylbenzene (38.36 µg/m3), and O and P-xylene (27.35, 23.6 µg/m3) were above the recommended levels. The indoor to outdoor ratios for benzene, toluene, ethylbenzene, O and P-xylene were 3.04, 2.36, 3.75, 4.89, and 6.54, respectively. Also, the toluene/benzene (T/B) ratio in indoor and outdoor was 20.9 and 2.68 respectively. Almost half of the technicians (49.12%) reported adverse health effects, including joint pain, itchy eyes and nose, and respiratory allergies. The IARC guideline suggests that there is a potential risk of cancer development for individuals in all salons with LCR values exceeding 10−6, but the HQ index values indicate no non-carcinogenic risk. The findings suggest that beauty salon workers and customers are at risk of developing health problems from exposure to BTEX compounds. Effective risk management strategies, such as proper ventilation, use of personal protective equipment, and substitution of harmful chemicals with safer alternatives, to minimize exposure and protect the health of salon workers and customers recommended.

Personal protection equipment: pockets, perceptions and equity – the untold truth of PPE: a reflexive thematic analysis

Personal protective equipment (PPE) is worn in a range of industrial environments by women and men alike. However, the majority of PPE is designed around male anthropometrics and the impacts of this on women are largely undocumented. Reflexive thematic analysis was used to develop themes from in-depth interviews with 30 women working in diverse roles in industrial environments, around their experiences of wearing PPE. Four themes developed: ‘There's nothing here for me’; ‘Collateral damage’; ‘Organisational culture and the burden of responsibility’; and ‘Personally protective women’. The findings significantly expand upon previous literature concerning: the reduced range of PPE available for women when compared with men; considerable fit and comfort issues; and physical, day-to-day and health-related consequences. This work evidences the increased PPE-related burden on women, and demonstrates fundamental links between women wearing ill-fitting or inappropriate PPE and their reduced sense of belonging, confidence and morale.

Factors Associated with Stress among Healthcare Personnel after COVID-19 in Northeast Thailand: A Cross-Sectional Study

Background The coronavirus disease (COVID-19) has affected people psychologically worldwide, particularly healthcare personnel. Even though the COVID-19 pandemic situation has eased, healthcare personnel must still perform their duties, which has resulted in psychological impacts, particularly stress. Objectives This study aimed to examine the risk factors associated with stress among healthcare personnel post-COVID-19 pandemic in northeast Thailand. Methods A cross-sectional analytic design was conducted from January to April 2023. One thousand and three hundred healthcare workers were selected from primary, secondary, and tertiary hospitals across 16 districts within Chaiyaphum province. The questionnaires were used to collect data, and the stress test 5 (ST-5) questionnaire was used to investigate stress among healthcare personnel. Results The overall stress rate for healthcare workers was 15.47%, including very severe (8.85%) and severe (6.62%). The factors associated with stress consisted of work position, environment of work, personal life such as education level and income, and responsibility for taking care of family members, in addition to experiencing quarantine from COVID-19 were more likely to have a high risk of stress problems among healthcare workers. Conclusion This result highlighted that the mental health of personnel should be in critical situations, and those found severely afflicted should undergo professional care. To prevent psychological issues, particularly stress, health organizations should be concerned with strong organizational management, which includes supporting bonuses and providing high-quality personal protective equipment (PPE) to healthcare staff.

Low level of awareness and prevention of hepatitis B among Congolese healthcare workers: urgent need for policy implementation.

The Democratic Republic of Congo (DRC) is a country with many public health challenges, including those related to the prevention and management of viral hepatitis B. Healthcare workers, who are at the frontline of patient care, are particularly at risk of contracting and spreading this virus, especially given its high prevalence in the general population. This paper examines the level of awareness and preventive measures among Congolese healthcare workers. Overall, the data show that health workers are under-immunized and lack formal training in hepatitis B prevention and management. In addition to limited awareness, health facilities are insufficiently involved in the implementation of standardized infection control protocols, the provision of personal protective equipment and routine hepatitis B vaccination programmes. There also appears to be a lack of clear and effective national policies outlining the main axes of infection control targets by 2030. This calls for urgent policy implementation focusing on mandatory vaccination, training, resource availability, adherence to infection control practices and comprehensive post-exposure management.

Exploring barriers to and facilitators of infection prevention and control practices in the Pediatrics and Child Health Department of Tikur Anbessa Specialized Hospital, Ethiopia

BackgroundAdherence to infection prevention and control (IPC) standards and guidelines by healthcare workers is essential for reducing the spread of healthcare-associated infections (HAIs). However, IPC practices among healthcare workers in low- and middle-income countries (LMICs), including Ethiopia, are generally inadequate. This research aims to identify the barriers to and facilitators of IPC practices in the Pediatrics and Child Health Department of Tikur Anbessa Specialized Hospital (TASH) in Ethiopia.MethodsWe employed a rapid ethnographic assessment (REA) approach for this study, using focus group discussions (FGDs), in-depth interviews (IDIs), and observations to collect data. Participants were selected from the Pediatrics and Child Health Department of TASH, and data collection took place in March and April 2022. Two FGDs and eight IDIs were conducted in the participants’ workplace within the department. Unstructured guides were used to facilitate the FGDs and IDIs. Nvivo version 10 software was used for data organization and analysis. The data were coded deductively through thematic analysis to identify similar ideas and concepts, based on the Systems Engineering Initiative for Patient Safety (SEIPS) model.ResultA total of 23 healthcare workers participated, with 15 in FGDs and 8 in IDIs. The study identified several barriers to IPC practices, including nonadherence to IPC practice protocols, lack of pre-employment training, space constraints, insufficient maintenance and repair of equipment, limited management engagement and support, shortage of resources and budget, incidents of needle stick injuries and infections, high workloads for healthcare workers, shortages of personal protective equipment and water supply, and inadequate waste management. We also identified some facilitators, including the existence of an IPC team and committee, a health education schedule for patients and visitors, morning sessions for healthcare providers, and the presence of television screens in waiting areas. By addressing the identified barriers and leveraging the facilitators, department heads, IPC team leaders, and decision-makers can develop targeted strategies and interventions to improve infection control, reduce the spread of HAIs, and ultimately enhance the quality of healthcare services.ConclusionThis study explored several barriers that contribute to inappropriate and suboptimal IPC practices in the study area. These barriers create significant challenges for healthcare workers and hindering their ability to effectively implement IPC practices. The findings highlight the complex and multifaceted nature of the problems, which not only affect the current working environment but also compromise the overall quality of care. The hospital administrator should address these critical issues to improving IPC practices and ensuring a safer healthcare environment.

Occupational health and safety among farmers: a comprehensive study in Central Anatolia, Turkey

BackgroundThe agricultural sector is vital for food production, economic stability, and environmental sustainability. However, it also poses significant occupational health and safety challenges due to factors such as heavy machinery usage, exposure to chemicals, and challenging environmental conditions.MethodThis cross-sectional study involved 366 farmers affiliated with the Yozgat Chamber of Agriculture in Turkey. Data on demographic characteristics, occupational factors, and work accidents were collected with interview technique between May and August 2023. While descriptive data were expressed as categories with numbers and percentages, chi-square analysis was used to compare the obtained answers with the status of having or not having a work accident. Binary logistic regression analysis was used to estimate the effect of independent variables on the probability of having a work accident.ResultsThe study revealed that 33.0% of farmers experienced work accidents in the last year. Most accidents occurred during work shifts (28.8%) and in the fall season (34.8%). Factors contributing to accidents included lack of personal protective equipment (51.5%) and transportation-related issues (36.4%). Logistic regression analysis indicated that working more than 8 h daily, working 5 days or more per week, and using bus/minibus transportation significantly increased the likelihood of experiencing work accidents.ConclusionFindings underscore the importance of implementing effective occupational health and safety measures, including proper training, provision of personal protective equipment, and improving transportation safety. Addressing these issues can enhance the well-being of agricultural workers and contribute to a safer working environment in the sector.

AGRICULTURAL WORKERS AND BURDEN OF MORBIDITY: A COMMUNITY-BASED CROSSSECTIONAL STUDY IN A RURAL BLOCK OF WEST BENGAL

Objective: Agriculture is one of the most hazardous occupations in developing and industrialized countries. Most agricultural workers in developing countries have poor housing conditions and an inadequate diet and are exposed to both general and occupational diseases. The study was undertaken to find out the prevalence of occupational morbidity and its associated risk factors among agricultural workers in a rural Block of West Bengal. Methods: The study was conducted among agriculture workers of Habra Block-I of the state of West Bengal. Multistage random sampling method was followed to select a total of 302 individuals who were distributed among the four villages according to the Probability Proportional to Size (PPS) method. Results: The majority of workers (58.6%) were suffering from nutritional pallor/anemia and dental carries/dental stains were 45.4%. Among other morbidities, 42% of workers were suffering from respiratory morbidity, 26.8% of workers were suffering from cardiovascular diseases, and 26.5% were suffering from hypertension. Duration of work (more than 8 h/day) was significantly associated with morbidity also other covariates such as age, sex, type of family, smoking status, and alcohol consumption had significant effects on morbidity among agriculture workers in both bivariate and multivariable linear regression. Conclusion: This research revealed not only the high prevalence of morbidities among the study population but also the occurrence of a large population with modifiable risk factors such as alcohol consumption, smoking, high load and long duration of work, poor personal hygiene, and non-use of personal protection equipment; the latter, if taken care, will reduce the morbidities of the agriculture workers.

Advancing Patient Safety: The Future of Artificial Intelligence in Mitigating Healthcare-Associated Infections: A Systematic Review.

Healthcare-associated infections are infections that patients acquire during hospitalization or while receiving healthcare in other facilities. They represent the most frequent negative outcome in healthcare, can be entirely prevented, and pose a burden in terms of financial and human costs. With the development of new AI and ML algorithms, hospitals could develop new and automated surveillance and prevention models for HAIs, leading to improved patient safety. The aim of this review is to systematically retrieve, collect, and summarize all available information on the application and impact of AI in HAI surveillance and/or prevention. We conducted a systematic review of the literature using PubMed and Scopus to find articles related to the implementation of artificial intelligence in the surveillance and/or prevention of HAIs. We identified a total of 218 articles, of which only 35 were included in the review. Most studies were conducted in the US (n = 10, 28.6%) and China (n = 5; 14.3%) and were published between 2021 and 2023 (26 articles, 74.3%) with an increasing trend over time. Most focused on the development of ML algorithms for the identification/prevention of surgical site infections (n = 18; 51%), followed by HAIs in general (n = 9; 26%), hospital-acquired urinary tract infections (n = 5; 9%), and healthcare-associated pneumonia (n = 3; 9%). Only one study focused on the proper use of personal protective equipment (PPE) and included healthcare workers as the study population. Overall, the trend indicates that several AI/ML models can effectively assist clinicians in everyday decisions, by identifying HAIs early or preventing them through personalized risk factors with good performance. However, only a few studies have reported an actual implementation of these models, which proved highly successful. In one case, manual workload was reduced by nearly 85%, while another study observed a decrease in the local hospital's HAI incidence from 1.31% to 0.58%. AI has significant potential to improve the prevention, diagnosis, and management of healthcare-associated infections, offering benefits such as increased accuracy, reduced workloads, and cost savings. Although some AI applications have already been tested and validated, adoption in healthcare is hindered by barriers such as high implementation costs, technological limitations, and resistance from healthcare workers. Overcoming these challenges could allow AI to be more widely and cost-effectively integrated, ultimately improving patient care and infection management.

Effectiveness of donning and doffing personal protective equipment education using video debriefing among Korean undergraduate nursing students

BackgroundThe use of appropriate personal protective equipment (PPE) in healthcare settings is a very important factor of infection control activities to prevent transmission of infection. In this study, we aimed to develop a non-face-to-face method that can reduce transmission of infection and an educational method that allows self-learning and self-training, and verify the effectiveness of a donning and doffing PPE education using video debriefing on third-year nursing students in clinical train.MethodsThe researcher assigned groups through random sampling using a random number table from the list of research subjects who agreed to participate. Therefore, 35 subjects in the experimental group with an education on donning and doffing PPE using video debriefing and 34 subjects in the control group with video-based training (VBT) were participated in April 2023 at a university in Incheon, South Korea. The evaluation phase involved verifying effects of the education on observer evaluation donningand doffing PPE performance and self-evaluation donningand doffing PPE performance. Satisfaction with the education also assessed immediately after intervention by the experimental group.ResultsThe experimental group had significantly higher scores for observer evaluationdonning (t = 7.84, p < .001) and observer evaluation doffing (t = 6.52, p < .001) PPE performances than the control group. However, there was no significant difference in self-evaluation donning (t = 0.98, p < .330) or doffing PPE performance (t = 0.17, p < .869) between the two groups. In the experimental group that applied video debriefing, learning satisfaction was 4.33 ± 0.82 points out of 5 points.ConclusionsThe education on donning and doffing PPE applying video debriefing was effective. If the education developed in this study is used as a self-learning method to improve the infection control capacity necessary to respond to a disaster crisis caused by infectious diseases, it is considered to be useful for preventing the transmission of infectious diseases in the future.

The Incidence of Clinical Injuries among Undergraduate Dental Students: A Prevention Protocol

Dental students are frequently exposed to percutaneous injuries (PCIs) due to the nature of their clinical work, which involves sharp instruments and close patient contact. The COVID-19 pandemic further emphasized the need for stringent biosafety measures and the use of personal protective equipment (PPE). Despite these precautions, injuries remain prevalent, highlighting the need for comprehensive education and training in biosafety and infection control. This study investigates the incidence and causes of injuries among undergraduate dental students during clinical sessions. This study was conducted at the Department of Dentistry, National and Kapodistrian University of Athens, focusing on injuries reported from 2021 to 2024. Data were collected through self-reported clinical records. The primary variables assessed included the type of injury, the instrument involved, the clinical procedure performed, and the immediate actions taken post-injury. Serological testing was conducted on students and patients to assess the risk of the transmission of bloodborne pathogens. The findings reveal a high prevalence of injuries, with needles being the most common cause (51.4%), followed by other tools such as dental probes (25.7%) and burs (8.6%). The most frequent injury type is piercing (74.2%), primarily affecting the fingers (88.6%). Periodontal treatments, restorative procedures, and endodontic treatments are the main activities leading to injuries, with 17.1% of injuries being caused by each. No statistically significant results are recorded. Despite regular medical records for most patients treated by injured students, serological testing shows significant positivity rates for HCV and HBV. Notably, most injured students demonstrate their commitment to safety by adhering to recommended post-exposure protocols, including wound cleaning, disinfecting, and serological testing. Furthermore, the impact of COVID-19 heightened the importance of personal protective equipment (PPE) and reinforced occupational health standards. Our study highlights the critical need for enhanced biosafety awareness and training among undergraduate dental students to reduce injury risks.
