The increasing demand for fresh fruits and vegetables has been accompanied by a rise in foodborne illness outbreaks linked to fresh produce. Traditional antimicrobial washing treatments, such as chlorine and peroxyacetic acid, have limitations in efficacy and pose environmental and worker health concerns. This study evaluated the effectiveness of organic acids (citric, malic, and lactic acid) and power ultrasound, individually and in combination, for the reduction in Salmonella enterica and Listeria monocytogenes on four fresh produce types: romaine lettuce, cucumber, tomato, and strawberry. Produce samples were inoculated with bacterial cocktails at 8–9 log CFU/unit and treated with organic acids at 2 or 5% for 2 or 5 min, with or without power ultrasound (40 kHz). Results showed that pathogen reductions varied based on the produce matrix with smoother surfaces such as tomato, exhibiting greater reductions than rougher surfaces (e.g., romaine lettuce and strawberry). Lactic and malic acids were the most effective treatments, with 5% lactic acid achieving a reduction of >5 log CFU/unit for S. enterica and 4.53 ± 0.71 log CFU/unit for L. monocytogenes on tomatoes. The combination of organic acids and power ultrasound demonstrated synergistic effects, further enhancing pathogen reduction by <1.87 log CFU/unit. For example, S. enterica on cucumbers was reduced by an additional 1.87 log CFU/unit when treated with 2% malic acid and power ultrasound for 2 min compared to malic acid alone. Similarly, L. monocytogenes on strawberries was further reduced by 1.84 log CFU/unit when treated with 5% malic acid and power ultrasound for 2 min. These findings suggest that organic acids, particularly malic and lactic acids, combined with power ultrasound, may serve as an effective hurdle technology for enhancing the microbial safety of fresh produce. Future research can include validating these treatments in an industrial processing environment. Full article

Aged-care services are in crisis through a combination of rising demand and increasing costs. Quality of care is often reported to be insufficient. Medical science has increased lifespans but the overmedicalisation of aged care may affect the financial sustainability and quality of care. Person-centred care was developed as a solution and is generally interpreted as being concerned with consumer choice. This study presents a human rights-based approach to a code of conduct for aged-care consumers and workers to ensure autonomy and participation in aged-care communities, which are fundamental to person-centred care. A test–retest cohort study was used to investigate the impact of a training module about a human rights-based code of conduct on the perspectives of new aged-care workers (n = 11) on a case scenario involving conflicting care priorities. Qualitative content analysis was used to categorise and count the participants’ responses. The analysis found that prior to training the majority of participants were focused on a medical and risk reduction model of care. After the training participants had a more expansive understanding of care needs and recognised the importance of client empowerment to enable clients to participate in decisions affecting their care. The results support the implementation of a human rights-based approach to worker training and client care; such an approach is consistent with person-centred care. Full article

Falls are a major safety concern in physically demanding occupations such as roofing, where workers operate on inclined surfaces under unstable postures. While inertial measurement units (IMUs) are widely used in wearable fall detection systems, they often fail to capture early indicators of instability related to foot–ground interactions. This study evaluates the effectiveness of plantar pressure sensors, alone and combined with IMUs, for fall detection on sloped surfaces. We collected data in a controlled laboratory environment using a custom-built roof mockup with incline angles of 0°, 15°, and 30°. Participants performed roofing-relevant activities, including standing, walking, stooping, kneeling, and simulated fall events. Statistical features were extracted from synchronized IMU and plantar pressure data, and multiple machine learning models were trained and evaluated, including traditional classifiers and deep learning architectures, such as MLP and CNN. Our results show that integrating plantar pressure sensors significantly improves fall detection. A CNN using just three IMUs and two plantar pressure sensors achieved the highest F1 score of 0.88, outperforming the full 17-sensor IMU setup. These findings support the use of multimodal sensor fusion for developing efficient and accurate wearable systems for fall detection and physical health monitoring. Full article

Water buffalo (Bubalus bubalis) are a primary source of milk in Pakistan, where bovine mastitis is a significant health issue among cattle, leading to substantial economic losses. Staphylococcus aureus is a predominant pathogen associated with mastitis; however, a detailed molecular characterization of the strains in the country remains limited. We previously characterized mastitis strains from the Hazara division of Khyber Pakhtunkhwa, Pakistan. In this study, we investigated mastitis cases in the Peshawar division, including samples from both animals and human farm workers for comparison. Higher rates of mastitis (67.27% of animals) and sub-clinical mastitis (91.03% of positive animals) were identified in Peshawar than for those (34.55% and 75.31%, respectively) previously observed in Hazara. Methicillin-susceptible S. aureus (MSSA) belonging to clonal complex 9 (ST2454) were predominant. Methicillin-resistant S. aureus (MRSA) belonging to ST22 and ST8 were also detected in the Nowshera district. While no S. aureus colonization was observed among animal handlers, evidence of hand contamination suggests a potential route for pathogen spread. Low levels of antibiotic resistance were noted amongst isolates, but higher rates were seen in MRSA. This study presents only the second comprehensive molecular investigation of S. aureus isolated from buffalo mastitis in Pakistan and indicates a concerning rise in mastitis within the province.

Background: Type 2 diabetes (T2D) is a major global health concern influenced by sociodemographic and lifestyle factors. This study compared T2D risk scores between commerce and industry sectors and assessed the associations of age, sex, education, physical activity, diet, and smoking with elevated risk. Methods: This cross-sectional study included 56,856 men and 12,872 women employed in the commerce (n = 27,448) and industry (n = 42,280) sectors across Spain. Anthropometric, clinical, and biochemical data were collected. Four validated T2D risk scores (QDscore, Finrisk, Canrisk, and TRAQ-D) were calculated. Multinomial logistic regression models estimated adjusted odds ratios (ORs) for high-risk categories by sociodemographic and lifestyle characteristics. Results: Women in the industrial sector had significantly higher age, BMI, waist circumference, and lipid levels than those in commerce; differences among men were less marked. Across all participants, higher T2D risk scores were independently associated with physical inactivity (OR up to 12.49), poor Mediterranean diet adherence (OR up to 6.62), industrial employment (OR up to 1.98), and older age. Male sex was strongly associated with high Canrisk scores (OR = 6.31; 95% CI: 5.12–7.51). Conclusions: Employment in the industrial sector, combined with sedentary behavior and poor dietary habits, is independently associated with higher predicted T2D risk. Workplace prevention strategies should prioritize multicomponent interventions targeting modifiable risk factors, especially in high-risk subgroups such as older, less-educated, and inactive workers.

Background/Objectives: Healthcare workers (HCW) have increased the risk of occupational stress injuries and adverse mental health outcomes, which were exacerbated during the COVID-19 pandemic. Understanding HCW psychological distress patterns and help-seeking behaviors can inform responsive resource development that may mitigate negative outcomes in future crises. This paper provides insights on monthly trends in HCW distress and support utilization at a large Canadian hospital over a 14-month period. Methods: As part of a hospital-wide wellness initiative during COVID-19, the STEADY program emailed monthly confidential wellness assessments to hospital staff from April 2020 to May 2021. The assessments included screens for burnout, anxiety, depression and posttraumatic stress, types of support accessed, and demographic information. Repeated cross-sectional data were summarized as monthly proportions and examined alongside longitudinal COVID-19 data. Results: A total of 2498 wellness assessments were submitted (M = ~168 monthly, range: 17–945). Overall, 67% of assessments had at least one positive screen for distress. Average positive screens were 44% for anxiety, 29% for depression, 31% for posttraumatic stress, and 53% for burnout. Despite high distress, most respondents used informal supports (e.g., family/friends), highlighting limited formal support use. Conclusions: HCWs experienced sustained high levels of psychological distress during the COVID-19 pandemic, with burnout remaining a predominant and persistent concern. The limited use of formal support services may indicate barriers to accessing these types of supports. Our findings underscore the need for accessible and acceptable mental health supports for HCW during prolonged crises. Full article

COVID-19 vaccine hesitancy in Pakistan is a barrier to optimal vaccine uptake and has been situated within a context of hesitancy towards other vaccines. A mixed-methods study was conducted during the initial COVID-19 vaccine roll-out in 2021 in four union councils in Peshawar, consisting of a cross-sectional survey, eight focus group discussions (FGDs) with community members and eight in-depth interviews with healthcare workers (HCWs) to assess perceptions toward vaccines. Multivariable logistic regression was used to assess factors associated with COVID-19 vaccine hesitancy. Of 400 survey participants, 57.3% were vaccine acceptant and 42.8% vaccine hesitant. Just over half (56.8%) perceived COVID-19 vaccines to be safe. Most (88%) reported trust in HCWs to provide accurate vaccine information. FGDs revealed that women received less information about the vaccine compared to men and cultural restrictions were barriers even for those willing to be vaccinated. Correlates of vaccine acceptance included male sex (aOR 2.25; 95% CI 1.29–3.91), age 50 years or greater (aOR 1.74; 95% CI 1.19–6.31), social network support (e.g., vaccine acceptance among an individual’s social network) in receiving COVID-19 vaccines (aOR 2.38; 95% CI 1.45–3.89), community concern about COVID-19 spread (aOR 2.84; 95% CI 1.73–4.66), and trust in HCWs to provide vaccine information (aOR 3.47; 95% CI 1.62–7.42). Future vaccine promotion should prioritize engaging community leaders, sharing transparent information, combatting misinformation and rumors, and implementing household-based interventions especially targeting the importance of vaccination among women and young people to increase uptake.

Background: Metabolic syndrome (MS) is a major public health concern linked to an elevated risk of type 2 diabetes and cardiovascular disease. Simple, reliable screening tools are needed for early identification, especially in working populations. Objective: To compare the diagnostic accuracy of body mass index (BMI), waist-to-height ratio (WtHR), triglyceride–glucose index (TyG), and waist–triglyceride index (WTI) for detecting MS based on NCEP ATP III and IDF criteria in a large cohort of Spanish workers. Methods: This cross-sectional study analyzed data from 386,924 Spanish workers. MS was diagnosed using NCEP ATP III and IDF definitions. The four indexes were evaluated by sex using a receiver operating characteristic (ROC) curve analysis. Area under the curve (AUC), optimal cut-off points, and Youden’s index were calculated. Results: TyG and WTI had the highest AUC values in men (0.911 and 0.901, respectively) for NCEP ATP III-defined MS, while WtHR and WTI achieved the best performance in women (0.955 and 0.953, respectively). WtHR outperformed BMI in all subgroups. Optimal cut-off values were identified according to sex and the definition of MS: TyG (8.95 men, 8.51 women), WtHR (0.54 men, 0.51 women), and WTI (170.6 men, 96.5 women), supporting their practical implementation in occupational health programs. All indexes showed significant discriminatory capacity (p < 0.001). Conclusions: TyG, WtHR, and WTI are more effective than BMI in detecting MS among Spanish workers, with sex-specific patterns. Their ease of use and diagnostic strength support their adoption in occupational health programs for early cardiometabolic risk detection. Full article

(1) Background: Occupational exposure to asbestos remains a significant public health concern due to its association with pleural cancer and other cancers. This cohort study examines the incidence of asbestos-related diseases among railway carriage maintenance workers exposed to asbestos between 1960 and 1979 in Bologna, Italy. (2) Methods: A cohort of 2197 male workers was followed from 1960 onwards, with data collected on asbestos exposure, smoking habits, and mortality outcomes. The association of asbestos exposure and smoking with the risk of pleural cancer and lung cancer was assessed using Cox proportional hazards regression models. (3) Results: This study identified a substantial burden of asbestos-related pleural cancer, with an exponential increase in risk over time since the beginning of exposure. Our results suggest the lack of a multiplicative effect of asbestos exposure and smoking on lung cancer risk. The Cox models showed a significant association between smoking and lung cancer risk, with a hazard ratio of 3.26 (95% CI: 1.10–9.64, p = 0.03), less significant for asbestos exposure, with a hazard ratio of 1.42 (95% CI: 0.66–3.06). (4) Conclusions: This study provides valuable insights into the long-term health effects of occupational asbestos exposure and underscores the complex interaction between asbestos exposure and smoking in the development of lung cancer.

Reflexivity is a metacognitive process traditionally applied to tasks and actions. Although emotions are a significant component of work life, the application of reflexivity to the emotional domain has received limited attention. This study addresses this gap by critically reviewing empirical evidence on reflexivity and emotions, aiming to understand this relationship and its outcomes in the workplace. A systematic literature review on Scopus and PsycINFO identified 722 records resulting in a final sample of 15 studies that met the PICO inclusion criteria and were included. These studies were analyzed according to recursively developed criteria. The findings showed that reflexivity affects emotions by considering them as the application domain; emotions, in turn, can trigger reflexivity. The outcomes of this relationship concern organizational learning and the workers’ role and identity. This relationship was more frequently investigated in high-emotion professional contexts and with a focus on specific professional roles. Due to the limited number of studies, the findings cannot be generalized. However, this study helps to define the role of reflexivity as a metacognitive competence applicable to emotions. Developing reflexivity within professional and organizational settings may help professionals regulate their own and others’ emotions by learning to detect, make sense of, and question critical emotional episodes.

This paper focuses on the complex dynamics that concern assembly line balance in the context of mass customization within manufacturing. In fact, the increase in demand for customized products has heightened the complexities associated with achieving optimal efficiency, productivity, product quality, and customer satisfaction. The research proposes a multi-criteria analysis of statistical methods to determine the fluctuation of parameters affecting the state of balance of an assembly line. A 3D matrix model is suggested to analyze the parameters managing the assembly line. This representation is executed using the MATLAB R2024b tool, and a methodology for finding the variability of parameters affecting balance through statistical approaches is proposed. We observed that changes in parameters such as task times, worker efficiency, or material flow led to significant changes in the line’s overall balance. As a result, static balancing becomes inadequate to deal with the complexities introduced by these highly variable parameters. The novelty of this paper consists of the innovative integration of multi-criteria statistical analysis and 3D matrix modeling to detect parameter variability and optimize assembly line balancing. Conventional static approaches are often unable to capture the process-dynamic aspect of modern manufacturing. This work presents a systematic methodology capable of identifying, quantifying, and moderating the variability of key operating parameters. This methodology, carried out using MATLAB-based simulations, is based on principal component analysis (PCA) and correlation analysis to detect critical factors influencing balancing efficiency. By structuring assembly line parameters in a 3D matrix representation, this research gives a holistic, data-based method for improving decision-making in balancing procedures. The research goes beyond theoretical modeling by applying the approach to a real automotive assembly line, validating its effectiveness and demonstrating its practical applicability in industrial conditions.

Despite growing academic interest in platform work and the gig economy, most existing research focuses on Western Europe, often neglecting the unique institutional and socioeconomic contexts of Central and Eastern Europe. This study addresses that gap by exploring the working conditions of platform workers in Poland, with particular emphasis on both material and psychosocial dimensions from the workers’ own perspectives. Data were collected from a nationally representative sample of 450 platform workers engaged in both online and location-based tasks, using the computer-assisted web interviewing (CAWI) method. The findings show a high level of perceived autonomy, with 74% of respondents feeling that they are independent in their work. However, autonomy is often limited by external factors, in particular, the availability of work. Workers who treat platform work as a side job are significantly more likely to report a sense of autonomy. In terms of health and safety, only 27% expressed concerns about negative health impacts, and 24% reported poor working conditions. Those who received health and safety information from the platform were more likely to acknowledge potential risks. Interestingly, workers relying on platform work as their primary source of income were more likely to perceive their work as safe, compared to those treating it as supplementary employment.

Background/Objectives: Coercive measures remain a common practice in mental health, despite ethical concerns, potential risks, and uncertain efficacy. Mental healthcare workers’ (MHCWs) attitudes toward coercion can influence their use. However, research in Italy is limited. This study aimed to investigate Italian MHCWs’ attitudes toward coercion and their associations with sociodemographic and professional characteristics. Methods: A cross-sectional study was conducted on 356 MHCWs from a mental health department in Southern Italy. Participants completed the Staff Attitude to Coercion Scale (SACS), which assesses negative, pragmatic, and positive attitudes toward coercion. Descriptive statistics (i.e., frequencies, percentages, means) and bivariate analyses (i.e., one-way ANOVA) were used to explore the associations between variables. Results: The majority of participants were male (56.7%), nurses (50.3%), and worked in acute psychiatric settings (52%), with a mean age of 51.08 years (±10.59) and 13.74 years (±12.14) of experience in mental health. Attitudes differed significantly according to age, sex, professional role, and work setting. More negative attitudes were found among staff in residential settings and non-caring roles (p < 0.001). Pragmatic attitudes were lower among older staff (p = 0.012) and among those in residential settings and non-caring roles (p < 0.001). Positive attitudes were higher among males (p = 0.001), nursing staff (p < 0.001), and staff in acute settings (p = 0.049). Conclusions: Italian MHCWs reported different attitudes toward coercion, which was influenced by personal and professional factors. These findings highlight the need for targeted interventions and policy strategies to promote attitudinal change, particularly in settings where positive attitudes are prevalent. Full article

Background: Breakthrough infections (BTIs) continue to occur among healthcare workers (HCWs) despite full COVID-19 vaccination, raising concerns about ongoing vulnerability in this high-risk group. In addition to initial BTIs, breakthrough reinfections (BTRs) have emerged as a challenge, with some HCWs experiencing multiple episodes of infection after vaccination. This study investigated the factors influencing breakthrough infection and reinfection rates among HCWs between January 2021 and December 2022 in Davao City, Philippines. Methods: This retrospective cohort study was conducted using secondary data from the Davao City Epidemiological Surveillance Unit, approved by the Department of Health. This study included 1011 fully vaccinated HCWs from various congressional districts. Results: BTI was observed in all HCWs included in the study. However, BTRs varied across occupational groups: medical technologists showed the highest reinfection rate (22.37%), followed by physicians (13.48%), and nurses/nurse aides (10.14%). Booster vaccination significantly reduced BTRs (5.83% vs. 11.18%, p = 0.0267). Occupation and institutional type were significant factors, with higher rates reported by physicians and in public hospitals (p = 0.0002 and p = 0.0041, respectively). The vaccine manufacturer, sex, age, and booster type showed no significant differences. Conclusion: These findings highlight the importance of targeted interventions for high-risk HCWs and emphasize the effectiveness of the booster vaccination. Full article

Workplace violence (WPV) is a prevailing global concern among healthcare providers (HCPs). Pharmacists may be more vulnerable to WPV than other HCPs due to being the most trusted, approachable, and accessible healthcare workers. However, in Saudi Arabia, there is little research on violence in the workplace among pharmacists working in different sectors. This is a cross-sectional survey study. An online survey was adopted from previous studies and distributed to a convenience sample of pharmacists by email and social media using a link to a web-based survey platform in QuestionPro. SPSS 28 was used for analysis. Logistic regression was employed to assess the association between WPV exposure and the participants’ characteristics. Three hundred and nineteen pharmacists participated in the study. A total of 156 (48.9%) reported exposure to workplace violence. Most participants had experienced verbal abuse (39.7%). Most offenders were male (84.6%), and aged 21–45 years (66.7%). Common causes included lack of a penalty (13.3%), and absence of reporting systems (11.4%). Seventy-eight percent of participants reported that the violence affected them negatively, leading to hopelessness (19.7%), and decreased work performance and productivity (15.1%). Logistic regression indicated that working as a staff (OR: 3.165; 95% CI 1.118–8.96, p = 0.030), working evening or night shift (OR: 2.4456; 95% CI 1.340–4.503, p = 0.004), and lacking procedure for reporting the violence (OR: 0.412; 95% CI 0.236–0.717, p = 0.002) were more likely to be victim of workplace violence than their counterparts. In Saudi Arabia, the risk of WPV events occurrence among pharmacists is high. The findings can guide the creation of appropriate policies, actions, and safety procedures to prevent and address WPV against pharmacists. Full article
