Evaluation of the Level of Psychological Distress in Construction Workers during the COVID-19 Pandemic in Southern Spain.

The COVID-19 pandemic posed a major challenge for construction companies, which were confronted with the need to prevent the enormous negative socio-psychological impact of the pandemic on their employees. The aim of this study was to evaluate the level of psychological distress among construction workers in an advanced phase of the COVID-19 pandemic in Andalusia, southern Spain. For this, a cross-sectional descriptive study was conducted using online questionnaires with data on sociodemographic variables and employment situation, COVID-19 pandemic-related data, and Goldberg's General Health Questionnaire (GHQ-12). A total of 860 questionnaires from all provinces of Andalusia, Spain, were collected between March and May 2022. Descriptive statistical analyses and non-parametric Mann-Whitney U and Chi-squared tests were performed, followed by logistic regression analysis. The incidence of psychological distress was higher among women, individuals under 43 years of age, those with a family income below EUR 1200, participants whose working conditions had been affected by the pandemic, those who had not received adequate means or specific training to protect themselves from infection, those who had experienced symptoms, those who had suffered side effects after vaccination, and those who had been hospitalised. The logistic regression analysis predicted the occurrence of psychological distress in this study by the effect of the pandemic on mental/emotional well-being, the working conditions affected during the pandemic, health-related variables, and the age of the worker. The correctly classified percentage was 75.1%. Assessing psychological distress in construction sectors may allow for the identification of vulnerable groups or even help to reduce the number of errors in daily practice and potential risks of occupational injury or illness.

Work engagement and sense of coherence as predictors of psychological distress during the first phase of the COVID-19 pandemic in Chile.

Objectives: The aim of this study was to analyse the relationship between sense of coherence, work engagement, and work environment variables as predictors of the level of psychological distress during the first phase of the COVID-19 pandemic in Chile. Methods: Cross-sectional descriptive study collected between April 22 and December 16, 2020, using non-probabilistic snowball sampling. The study variables and instruments were socio-demographic variables, work engagement (UWES-9 scale), sense of coherence (Antonovsky SOC-13 scale), and psychological distress (GHQ-12 scale). Multivariate analysis and binary logistic regression were performed including the scores of the three questionnaires and other variables such as effectiveness, safety, stress, health perception, and sex. Finally, the CHAID technique was applied to create a segmentation tree. Results: 72.7 % of participants had high levels of psychological distress, more predominantly among women, with work stress and low sense of coherence acting as the most influential mediators in generating psychological distress, and even more so when both were combined. Low work engagement and the availability of safe and effective means to prevent infection were predictors of psychological distress among workers. Conclusion: During the first phase of the COVID-19 pandemic, factors that contributed to psychological distress in the Chilean population were identified. These included a fair or poor perception of health, being a woman, work-related stress, availability of safety measures, low level of work engagement, and low level of sense of coherence. Identifying these factors may help prevent similar effects in future phases of the current pandemic or in future pandemics.

Psychological distress among unemployed migrants settling in southwestern Spain: A cross-sectional study.

Migrants living in the informal settlements of Southern Spain tend to have precarious employment and poor living conditions, making then vulnerable to mental health issues. This study aimed to assess psychological distress in a sample of unemployed migrants residing in informal settlements in the province of Huelva (southern Spain), during the fourth wave of the COVID-19 pandemic. A descriptive cross-sectional study was conducted during the months of April to June 2021, through a heteroadministered questionnaire, in informal settlements. The measurement instrument was the General Health Questionnaire (GHQ-12), used to analyze psychological distress, and other sociodemographic and health-related variables. Univariate and bivariate descriptive data analysis were performed, using the nonparametric statistics Mann-Whitney U test, Kruskal-Wallis H test, and Tau ß correlation. A categorical regression analysis was performed to study the relationship between psychological distress and the rest of the variables. The sample consisted of 317 subjects, 83.9% of whom were males, and the mean age was 33.4 years (SD = 10.7 years). The mean score obtained in the GHQ-12 questionnaire was 13.69 points (SD = 3.86). Significant differences were found between levels of psychological distress and substance abuse (H = 14.085; P = .049), people who wished to stay in Spain (t = 6987; P = .049), people who experienced isolation due to COVID-19 contact (t = 1379.5; P = .001), people who needed medical assistance due to COVID-19 (t = 7.990; P = .018), and those who reported having chronic illnesses (t = 2686.5, P = .02). The mean score of psychological distress indicates general high levels of psychological distress. Participants who had experienced isolation due to COVID-19 contact, who consumed substances, and who had chronic illnesses reported the highest levels of psychological distress.

Patient-journey of fibromyalgia patients: A scoping review.

BACKGROUND: Fibromyalgia (FM) is a chronic disease characterized by widespread pain. Although much is known about this disease, research has focused on diagnosis and treatment, leaving aside factors related to patient's experience and the relationship with healthcare system. OBJECTIVES: The aim was to analyze the available evidence on the experience of FM patients from the first symptoms to diagnosis, treatment, and follow-up. METHODS: A scoping review was carried out. Medline and the Cochrane Library were searched for original studies or reviews dealing with FM and focusing on "patient journey". Results were organized using a deductive classification of themes. RESULTS: Fifty-four articles were included in the qualitative synthesis. Five themes were identified: the patient journey, the challenge for the health systems, a complex doctor-patient relationship, the importance of the diagnosis, and the difficulty of standardizing the treatment. CONCLUSIONS: This scoping review confirms the negative impact of FM on the patient, their social environment, and health systems. It is necessary to minimize the difficulties encountered throughout the diagnosis and follow-up of patients with FM.

Opioids and fibromyalgia: frequency of use and factors associated with increased consumption in patients remitted to a tertiary care center.

BACKGROUND: Opioids are not recommended for fibromyalgia. OBJECTIVE: To investigate the frequency of opioid use in a large cohort of fibromyalgia patients and to identify factors associated with opioid consumption. METHODS: A retrospective, observational study of a large fibromyalgia cohort in a tertiary care center. We assessed fibromyalgia severity, functional capacity, anxiety, depression, drugs consumption and the patient's impression of change. We compared strong opioid consumers (SOC) and non-SOC. Inferential statistical and logistic regression analysis were used to identify factors associated with opioid consumption, and ANOVA for repeated measurements. RESULTS: We found a prevalence of 9.2% of SOC (100 patients) among 1087 patients in the cohort. During the last four years there was a significant increase on the incidence of SOC up to 12.8% (p = 0.004). There were no differences in demographic variables between SOC and non-SOC. Clinical variables were significantly more severe in SOC, and they consumed more non-opioid drugs (p < 0.0001). Opioid consumption was independently associated with other non-opioid drugs (Odds ratio 1.25, CI: 1.13-1.38), but not with the fibromyalgia severity. At three months, 62% of the patients had opioid withdrawal. There were no statistical differences in the fibromyalgia severity at the initial evaluation, or the patient's impression of change compared with those patients who continued opioids. Coping strategies were better in those patients who withdrew opioids (p = 0.044). CONCLUSIONS: We observed an increase in opioid prescriptions during the last four years. Opioid consumption was associated with concomitant use of non-opioid drugs, but it was not associated with fibromyalgia severity.

Can Virtual Reality be Used for the Prevention of Peer Sexual Harassment in Adolescence? First Evaluation of the Virtual-PRO Program.

Objective: The present study analyzed the Virtual-PRO program's efficacy in preventing peer sexual harassment by promoting the bystanders' active intervention and incorporating a virtual reality (VR) component. The impact of the program on sexist attitudes, moral disengagement, the intention to intervene as bystanders, and the involvement in sexual aggression and victimization was tested. Method: Virtual-PRO is a VR-enhanced sexual harassment curricular prevention program of six one-hour sessions. The evaluation comprised a pre-test, a post-test after the intervention, and a follow-up measure at three months. In the study, 579 Spanish adolescent students aged between 12 and 17 years (M = 14.76, SD = 0.88; 47.1% boys) were randomly grouped into experimental (n = 286) and control (n = 293) conditions. Results: The Virtual-PRO program effectively controlled participants' levels of sexism and reduced moral disengagement in the experimental group compared to the control group three months after the intervention. The program also showed positive results in changing bystander behavior, increasing the intention to intervene when the victim was not a friend. Finally, visual/verbal and online victimization decreased in the experimental group and increased in the control group. No differences were found for physical sexual victimization and sexual aggression. Conclusions: The first trial of the Virtual-PRO program is promising and highlights the use of VR as a sexual harassment prevention tool. Follow-up measures are essential to determine the impact of interventions accurately.

Objetivo: El presente estudio analiza la eficacia del programa Virtual-PRO en la prevención del acoso sexual entre iguales promoviendo la intervención activa de los espectadores mediante el uso de la realidad virtual (RV). Se comprobó el impacto del programa en las actitudes sexistas, la desconexión moral, la intención de intervenir como espectadores y la implicación en agresión y victimización sexual. Método: Virtual-PRO es un programa curricular compuesto por seis unidades que incorpora la RV para mejorar la prevención del acoso sexual. La evaluación incluyó una medida pre-test, un post-test después de la intervención y una medida de seguimiento a los tres meses. En el estudio participaron 579 estudiantes españoles de entre 12 y 17 años (M = 14.76, DT = 0.88, 47.1% chicos), agrupados aleatoriamente en grupo experimental (n = 286) y control (n = 293). Resultados: El programa Virtual-PRO controló eficazmente los niveles de sexismo y redujo la desconexión moral en el grupo experimental en comparación con el grupo de control tres meses después de la intervención. También mostró resultados positivos en el cambio del comportamiento de los espectadores, mejorando la intención de intervenir cuando la víctima no era amigo o amiga. Por último, la victimización visual/verbal y online disminuyó en el grupo experimental y aumentó en el grupo control. No se encontraron diferencias en victimización sexual física y agresión sexual. Conclusiones: El primer ensayo del programa Virtual-PRO es prometedor y pone de relieve el uso de la RV como herramienta eficaz para la prevención del acoso sexual. Las medidas de seguimiento son esenciales para determinar con precisión el efecto de las intervenciones.

Factors Influencing Occupational Stress Perceived by Emergency Nurses During Prehospital Care: A Systematic Review.

Objective: To assess personal and work-related factors influencing the stress levels of nurses during prehospital care. Specifically, to identify associations between the level of perceived stress, the degree of professional experience, and the level of knowledge. Secondly, to examine the relationship between stress levels and violence in the work environment. And third, to investigate the main protective factors against work-related stress during prehospital care. Methods: Systematic review in PubMed, WOS, Enfispo, Cochrane, and LILACS databases following the PRISMA methodology (last search 08/Aug/2023). Following the PECO framework, studies on occupational stress factors in ambulance emergency nurses were investigated. Studies in English or Spanish, from 2013 to 2023, and only research articles were admitted, thus excluding reviews, dissertations, and grey literature. Possible bias and level evidence were assessed using critical appraisal tools and GRADE. This protocol was registered in PROSPERO with code CRD42023446080. Results: Fourteen articles were selected, and n=855 prehospital nurses were identified. One study was a clinical trial, and the others were observational and qualitative. The level of evidence was very low (n=7), low (n=6), and moderate (n=1); any study was excluded due to methodological bias. Five categories of stressors were extracted: the management of the health service (ie, workload organisation, and resources), patient care (mainly paediatric care), interpersonal stressors (relationship with peers), environmental factors (exposure to injuries), and personal factors (training, experience, and coping strategies). Violence at work is frequent for prehospital nurses, implying both verbal and physical aggressions. Support from peers was associated with positive results against stress. Conclusion: Managing workload and improving resources in the work environment are essential to reduce fatigue and allow emotional processes to be addressed. Providing workers with coping skills also imposes on them the responsibility to cope with stress. Collective awareness is the main element in reducing the incidence of stress.

Risk perception of healthcare workers in the first wave of the COVID-19 pandemic in Brazil.

Objectives: To validate the items of the Emotional Impact Questionnaire coronavirus disease-2019 (COVID-19) related to risk perception, estimating its degree, among healthcare workers in the first wave of COVID-19 pandemic, identifying possible associated factors.Methods: cross-sectional study in 1872 healthcare workers of Brazil. The population was characterized by sociodemographic and occupational information, knowledge about COVID-19, quality of information received, risk perception and preventive measures about the disease, and sense of coherence. Results: Being divorced, having a chronic disease, spending more than 1 h per day getting informed about COVID-19, and always or almost always wearing a mask regardless of symptoms, as well as self-perception of health were associated with high-risk perception. An inverse association was found between risk perception, sense of coherence and not knowing if one has had occasional contact with confirmed COVID-19 cases. Conclusion: Risk perception is influenced by emotions, experiences, and knowledge. Sense of coherence and resilience have a role in reducing risk perception. Understanding risk perception is crucial for developing effective strategies to mitigate the impact of the COVID-19 pandemic and other similar scenarios.

Phylogenomic, structural, and cell biological analyses reveal that Stenotrophomonas maltophilia replicates in acidified Rab7A-positive vacuoles of Acanthamoeba castellanii.

Acanthamoeba species are clinically relevant free-living amoebae (FLA) ubiquitously found in soil and water bodies. Metabolically active trophozoites graze on diverse microbes via phagocytosis. However, functional studies on Rab GTPases (Rabs), which are critical for controlling vesicle trafficking and maturation, are scarce for this FLA. This knowledge gap can be partly explained by the limited genetic tools available for Acanthamoeba cell biology. Here, we developed plasmids to generate fusions of A. castellanii strain Neff proteins to the N- or C-termini of mEGFP and mCherry2. Phylogenomic and structural analyses of the 11 Neff Rab7 paralogs found in the RefSeq assembly revealed that eight of them had non-canonical sequences. After correcting the gene annotation for the Rab7A ortholog, we generated a line stably expressing an mEGFP-Rab7A fusion, demonstrating its correct localization to acidified macropinocytic and phagocytic vacuoles using fluorescence microscopy live cell imaging (LCI). Direct labeling of live Stenotrophomonas maltophilia ESTM1D_MKCAZ16_6a (Sm18) cells with pHrodo Red, a pH-sensitive dye, demonstrated that they reside within acidified, Rab7A-positive vacuoles. We constructed new mini-Tn7 delivery plasmids and tagged Sm18 with constitutively expressed mScarlet-I. Co-culture experiments of Neff trophozoites with Sm18::mTn7TC1_Pc_mScarlet-I, coupled with LCI and microplate reader assays, demonstrated that Sm18 underwent multiple replication rounds before reaching the extracellular medium via non-lytic exocytosis. We conclude that S. maltophilia belongs to the class of bacteria that can use amoeba as an intracellular replication niche within a Stenotrophomonas-containing vacuole that interacts extensively with the endocytic pathway.IMPORTANCEDiverse Acanthamoeba lineages (genotypes) are of increasing clinical concern, mainly causing amoebic keratitis and granulomatous amebic encephalitis among other infections. S. maltophilia ranks among the top 10 most prevalent multidrug-resistant opportunistic nosocomial pathogens and is a recurrent member of the microbiome hosted by Acanthamoeba and other free-living amoebae. However, little is known about the molecular strategies deployed by Stenotrophomonas for an intracellular lifestyle in amoebae and other professional phagocytes such as macrophages, which allow the bacterium to evade the immune system and the action of antibiotics. Our plasmids and easy-to-use microtiter plate co-culture assays should facilitate investigations into the cellular microbiology of Acanthamoeba interactions with Stenotrophomonas and other opportunistic pathogens, which may ultimately lead to the discovery of new molecular targets and antimicrobial therapies to combat difficult-to-treat infections caused by these ubiquitous microbes.

Psychological distress in healthcare workers during COVID-19 pandemic: A systematic review.

OBJECTIVES: Healthcare workers serving during the COVID-19 pandemic may have been exposed to high work overload, which may have had an impact on their physical, mental, and social health. The aim of this study was to assess the risk factors associated with psychological distress among healthcare workers serving during the COVID-19 pandemic from January 2020 to December 2022. METHODS: A systematic review was conducted based on the 2020 PRISMA statement. Articles were searched in the Pubmed, Scopus, Web of Science, CINAHL, and PsycINFO databases. RESULTS: A total of 59 articles were included in this systematic review. It was observed that the prevalence of psychological distress during the COVID-19 pandemic was high. Female sex, being a nurse, being young, living alone/being single, and having a chronic disease or psychiatric disorder history are the main risk factors at the personal level. Other occupational and pandemic-related factors such as having many years of work experience, the presence of COVID-19 symptoms and contact history, not enough sleep, having lower family support and limited social relationships, fear of infecting friends and family, having a reduced perception of protection by personal protective equipment, working on the frontline, and having longer service duration were found to be factors influencing the development of psychological distress during the COVID-19 pandemic. CONCLUSIONS: There are personal, interpersonal, and organizational risk factors that can lead to the occurrence of psychological distress among healthcare staff working during the COVID-19 pandemic.

Regulation of lipolysis by 14-3-3 proteins on human adipocyte lipid droplets.

Adipocyte lipid droplets (LDs) play a crucial role in systemic lipid metabolism by storing and releasing lipids to meet the organism's energy needs. Hormonal signals such as catecholamines and insulin act on adipocyte LDs, and impaired responsiveness to these signals can lead to uncontrolled lipolysis, lipotoxicity, and metabolic disease. To investigate the mechanisms that control LD function in human adipocytes, we applied proximity labeling mediated by enhanced ascorbate peroxidase (APEX2) to identify the interactome of PLIN1 in adipocytes differentiated from human mesenchymal progenitor cells. We identified 70 proteins that interact specifically with PLIN1, including PNPLA2 and LIPE, which are the primary effectors of regulated triglyceride hydrolysis, and 4 members of the 14-3-3 protein family (YWHAB, YWHAE, YWHAZ, and YWHAG), which are known to regulate diverse signaling pathways. Functional studies showed that YWHAB is required for maximum cyclic adenosine monophosphate (cAMP)-stimulated lipolysis, as its CRISPR-Cas9-mediated knockout mitigates lipolysis through a mechanism independent of insulin signaling. These findings reveal a new regulatory mechanism operating in human adipocytes that can impact lipolysis and potentially systemic metabolism.

Clinical and Endoscopic Differences Between Patients With Barrett's Esophagus With and Without Dysplasia/Adenocarcinoma.

INTRODUCTION: Barrett's esophagus (BE) is the main precursor of esophageal adenocarcinoma (EAC). This study aimed to identify the risk factors associated with BE progression to dysplasia or EAC in a Latin population. METHODS: The study is a retrospective analysis of a single-center cohort of patients with BE, evaluated from 2002 to 2012. RESULTS: We identified 420 patients with BE; 281 (66.9%) of them were men with a mean age of 57.2 ± 15.3 years. Among all BE patients evaluated, 81 (19.3%) had progression to some degree of dysplasia/EAC. The mean follow-up was 5.6 years. Multivariate analysis showed that age (OR = 1.03), cigarette smoking (OR = 3.05), long-segment BE (OR = 4.81), and a visible lesion on BE (OR = 6.94) were associated with progression to dysplasia/EAC. CONCLUSION: In Latin patients with BE, age, cigarette smoking, long-segment BE, and the presence of lesions were associated with the presence of dysplasia/EAC.

Assessment of Levels of Anxiety and Fear of Covid-19 in a Population of Pregnant Women in Spain.

Objective: The aim of the study was to assess the levels of fear and anxiety in the particularly vulnerable population group of women during pregnancy. Methods: Cross-sectional study between March 2022 and July 2022 involving 978 pregnant women aged 16 to 50 years. It was carried out based on the scale for the assessment of fear and anxiety in pregnant women (AMICO_Pregnant) and the collection of sociodemographic data. Normality analysis was performed prior to univariate and bivariate statistical analysis. Results: The sample was composed of a total of 978 pregnant women. The mean of the AMICO_Pregnant scale was intermediate (5.04 points; SD=2.36). The bivariate analysis showed a statistically significant relationship between the AMICO_Pregnant scale and the following variables: vaccination schedule status, contact with the disease, weeks of gestation, altered delivery or birth plan. Conclusion: Women with pregnancies closer to term, with no contact with the disease, without a complete vaccination schedule, or who had undergone changes in their delivery or birth plans, showed higher levels of fear and anxiety.

Adaptation and psychometric study of the scale for the measurement of fear and anxiety of COVID-19 disease in pregnant women (AMICO_Pregnant).

Objective: The aim of this research was to adapt and explore the psychometric properties of a specific scale to assess the levels of fear and anxiety of COVID-19 disease in pregnant women. Methods: An adaptation phase, by a panel of experts, and a psychometric descriptive cross-sectional study were carried out on the final version of the 16-item, self-administered AMICO_Pregnant scale. Univariate and bivariate analyses were carried out, followed by exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The consistency of the scale was assessed using the Omega coefficient and Cronbach's Alpha. Results: With a sample of 1,013 pregnant women living in Spain and over 18 years of age, the mean age was 33 years. The scale showed a bifactor structure (anxiety and fear) that was confirmed with good fit parameters. Reliability was assessed in terms of internal consistency by calculating Cronbach's Alpha coefficient (0.95) and McDonald's Omega coefficient (0.94) as indicators of robustness of the scale's reliability. Conclusion: The AMICO_Pregnant scale of 16 items with scores ranging from 1 to 10 is a valid and reliable tool to assess levels of anxiety and fear of COVID_19 in Spanish pregnant women. Pregnant women have shown moderate levels of anxiety and fear regarding the COVID_19 disease in the final phase of the pandemic.

A distinct class of hematopoietic stem cells develop from the human yellow bone marrow.

Aging and metabolic diseases are accompanied by systemic inflammation, but the mechanisms that induce this state are not known. We developed a human bone-marrow organoid system to explore mechanisms underlying metabolic-disease associated systemic inflammation. We find that a distinct type of hematopoietic stem cell (HSC) develops in the adipose-rich, yellow bone marrow, which is known to gradually replace the hematopoietic red marrow as we age and during metabolic disease. Unlike HSCs derived from the red bone marrow, HSCs derived from the yellow bone marrow have higher proliferation rates, increase myeloid differentiation, skew towards pro-inflammatory M1 macrophage differentiation, and express a distinct transcriptomic profile associated with responsiveness to wounding. Yellow marrow-derived HSCs express higher levels of the leptin receptor, which we find to be further increased in patients with type 2 diabetes. Our work demonstrates that the human long bone yellow marrow is a niche for a distinct class of HSCs which could underlie hematopoietic dysfunction during aging and metabolic disease processes suggesting a shared inflammaging mechanism.

Toward sustainability and resilience in Chilean cities: Lessons and recommendations for air, water, and soil issues.

Achieving sustainability and resilience depends on the conciliation of environmental, social, and economic issues integrated into a long-term perspective to ensure communities flourish. Many nations are transitioning toward both objectives, while at the same time addressing structural concerns that have not allowed them to look after the environment in the past. Chile is one of these nations dealing with such challenges within a particular administrative context, an increasing environmental awareness, and a set of unique and complex geophysical boundaries that impose a plethora of hazards for cities, ecosystems, and human health. This paper presents recent accomplishments and gaps, mostly from an environmental perspective, on issues related to air pollution, the urban water cycle, and soil contamination, in the path being followed by Chile toward urban sustainability and resilience. The focus is on the bonds between cities and their geophysical context, as well as the relationships between environmental issues, the built environment, and public health. The description and diagnosis are illustrated using two cities as case studies, Temuco and Copiapó, whose socioeconomic, geographical, and environmental attributes differ considerably. Particulate matter pollution produced by the residential sector, drinking water availability, wastewater treatment, stormwater management, and soil contamination from the mining industry are discussed for these cities. Overall, the case studies highlight how tackling these issues requires coordinated actions in multiple areas, including regulatory, information, and financial incentive measures. Finally, the policy analysis discusses frameworks and opportunities for Chilean cities, which may be of interest when conceiving transitional paths toward sustainability and resilience for other cities elsewhere.

Stress, fear, and anxiety among construction workers: a systematic review.

Objectives: The aim of this review was to assess the possible risk factors arising from working conditions, that could have an impact on the stress, fear, and anxiety of construction workers. Methods: A systematic review was conducted following the PRISMA format in the Pubmed, Cochrane, Web of Science, Scopus, and PsycInfo electronic databases on February 3, 2023, using the following key words: anxiety, stress, fear, and construction workers. Methodological quality was assessed using the critical appraisal tools of the Joanna Briggs Institute. Results: A total of 35 studies were included. The results showed a number of conditioning factors for stress, anxiety, and fear among construction workers such as age, inappropriate safety equipment, safety culture, high workload and long working hours, physical pain, low social support from direct supervisor or co-workers, lack of organizational justice and lack of reward, financial situation, maladaptive coping strategies, and characteristics of the pandemic. Conclusions: There are a number of risk factors related to working conditions, organizations, and individuals that can affect the levels of stress, anxiety, and fear among construction workers, such as age, work hardship, safety culture and, especially, the long hours that construction professionals work. This may lead to an increase in the number of occupational accidents and higher associated fatality rates.
