BackgroundMusculoskeletal symptoms are common among bovine practitioners, yet evidence on their prevalence and associated factors remains limited in developing countries.Objectiveto determine the prevalence of shoulder pain and associated factors in Brazilian veterinarians involved in the reproductive management of beef cattle, and to compare shoulder muscle strength and handgrip strength between the dominant and non-dominant sides.MethodsIn this cross-sectional study, 148 veterinarians were recruited during an annual conference. Sociodemographic, occupational and lifestyle factors were assessed. Pain intensity, disability (Shoulder Pain and Disability Index-SPADI, and Neck Disability Index-NDI), lifestyle (Fantastic Lifestyle Questionnaire), and muscle strength (shoulder abduction, lateral rotation and handgrip dynamometry) were evaluated. Predictors of shoulder pain were identified through a binary logistic regression analysis (n = 98), and variables were compared between the dominant and non-dominant sides (n = 50) using the Wilcoxon test.ResultsShoulder pain was reported by 69% of veterinarians. Neck pain increased the odds of shoulder pain, whereas work-related factors were not associated. Current smokers were less likely to report shoulder pain than non-smokers. Participants were mostly men (mean aged 35 years) with moderate pain intensity, low SPADI and NDI scores and good lifestyle habits. Shoulder muscle strength did not differ between sides; although dominant handgrip was greater than non-dominant.ConclusionShoulder pain is highly prevalent among Brazilian veterinarians working in the reproductive management of beef cattle. Neck pain appears to be a key associated factor for shoulder pain, but not work characteristics, highlighting the importance of early stages of rehabilitation management to prevent further musculoskeletal disorders.

BackgroundHealthcare worker burnout is a global public health crisis, yet evidence on its urban-rural disparities in resource-limited regions like China's inland provinces remains scarce.ObjectiveThis study assessed socio-demographic and occupational predictors of burnout among healthcare workers in Henan Province, China.MethodsA cross-sectional, descriptive, and correlational study was conducted from August-September 2024 among 5189 healthcare workers across urban and rural settings. Burnout was measured using the Maslach Burnout Inventory (MBI). Predictors included work setting, work pressure, promotion opportunities, childcare support, and resource levels.ResultsBurnout patterns showed stark urban-rural contrasts. Rural workers had less than half the risk of emotional exhaustion (EE) (OR = 0.38-0.40), likely due to more manageable workflows. In contrast, urban workers under high pressure faced nearly ten times the risk (OR = 9.57), driven by clinical and academic demands. Adequate promotion opportunities were linked to a 23% lower risk of burnout (OR = 0.77). Notably, strong childcare support (for ≥2 children) halved the risk of EE (OR = 0.46). Despite an overall low sense of personal accomplishment in the sample, rural workers reported significantly higher odds (OR = 2.55-2.88) of high PA.ConclusionsStructural job demands and cultural factors significantly influence burnout disparities. While derived from a study in Henan Province, these findings offer insights likely applicable to other resource-limited settings internationally. Interventions prioritizing workload redistribution, transparent career pathways, and family-friendly policies are essential to mitigate burnout and enhance workforce sustainability in resource-limited settings. Clinicians and policymakers should integrate Job Demands-Resources (JD-R) principles with cultural context to optimize institutional support systems across diverse healthcare environments.

BackgroundNursing practice demands a high level of manual dexterity and hand grip strength for tasks such as medication administration, patient handling, and operating medical equipment. Burnout and self-efficacy are common psychological factors among nursing students that may potentially influence the development or expression of these physical skills. However, the nature of this relationship is not well understood.ObjectiveTo investigate the relationship between levels of self-efficacy and burnout, with hand grip strength and hand dexterity, in nursing students at King Saud University.MethodsA cross-sectional study was conducted with 57 nursing students average age was 21.98 ± 1.70 years. Maslach Burnout Inventory-Student Survey and General Self-Efficacy Scale were used. Hand dexterity was evaluated using Purdue Pegboard Test and hand grip strength was assessed using a dynamometer. Correlation analysis was used to determine the associations between the variables.ResultsNo significant correlations between overall burnout or its emotional exhaustion and cynicism sub-scores, and hand function (p > .05). However, professional efficacy showed a significant positive correlation with Purdue Pegboard Assembly (r_s = .29, p = .03) and Purdue Pegboard Both Hands scores (r_s = .32, p = .01). General self-efficacy also correlated positively with Purdue Pegboard Assembly (r_s = .34, p = .009), but no other significant correlations were observed.ConclusionsThese results may have implications for student support and interventions aimed at enhancing self-efficacy, potentially optimizing the development of skills critical for future nursing practice.

BackgroundHand grip and torque strength are critical in occupational tasks, particularly in industries requiring manual tool handling. Ergonomic designs tailored to workers' anthropometric characteristics can help reduce Musculoskeletal Disorders (MSDs), a leading cause of workplace absenteeism. While several studies have examined anthropometric influences on grip strength, predictive models integrating machine learning remain limited.ObjectiveThis study aims to identify the most influential anthropometric variables in predicting hand grip and torque strength among economically active individuals, using machine learning models to enhance force estimation for ergonomic applications.MethodsA cross-sectional study was conducted with 382 participants (194 women, 188 men), aged 15-65 years. Three predictive models-Linear Regression (LR), Random Forest (RF), and AdaBoost (AB)-were evaluated based on Mean Absolute Error (MAE), Mean Squared Error (MSE), and Explained Variance Score (EVS). Feature importance was analyzed using Mean Decrease in Impurity (MDI) for RF and AB and coefficient magnitude for LR.ResultsLR was the best model in four cases, while RF and AB performed better in nonlinear relationships. In women, grip and torque strength depended on hand and wrist dimensions, whereas in men, variables such as palmar length and lateral reach played a more significant role.ConclusionsAnthropometric characteristics significantly influence manual strength, highlighting the need for sex-specific ergonomic adaptations. Machine learning models improve predictive accuracy, supporting the design of interventions to reduce MSD risks.

BackgroundDespite the wide usage of Globally Harmonized System (GHS) pictograms in Iranian work settings, there is limited evidence that workers comprehend these signs. Misinterpreting GHS signs can result in hazardous exposures, accidents, and reduced workplace safety.ObjectiveThis study vitally reviews available research to determine the level of comprehension of GHS symbols among Iranian workers.MethodsIn this systematic review, a comprehensive search was performed in international databases (Embase, Scopus, PubMed, and Web of Science) and Persian (SID, IranMedex, Magiran, and IranDoc). Relevant articles in these databases were extracted by searching keywords such as GHS pictograms, chemical labeling comprehension, and Iran from 2015 to 2025. To extract the required data, all parts of the studies were reviewed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020.ResultsOut of the 14 collected articles, 10 articles were selected as final articles, of which five, three, one, and one article dealt with laboratory staff and students, industrial workers, hospital service workers, and farmers, respectively. The signs "flammable substances" (Comprehension Ratio (CR) (%): 39.5-98.8) and "risk of explosion" (CR (%):13-100) had the highest and the signs "skin irritant" (CR (%): 1.6-82) and "gas under pressure" (CR (%): 3.5-88.8) had the lowest comprehension among the GHS signs. Training, safety culture, education level, and gender were among the factors affecting the perception of these pictograms.ConclusionThis systematic review reveals that although GHS pictograms are a critical tool in safety communication, their inadequate perception in Iranian workplaces remains a significant challenge. This review highlights the requirement to review the design (e.g., simplifying signs or adding text labels), training (e.g., local language programs customized to a particular setting), and implementation (e.g., periodic assessments and specific workplace adjustments) of these international signs, taking into account local and cultural characteristics.

BackgroundShift work is a major occupational health issue, disrupting circadian rhythms and increasing risks for physical, psychological, and social problems. Its impact on sexual function and sexual quality of life among female healthcare workers remains underexplored.ObjectiveThis study examined the impact of shift work on sexual function and sexual quality of life among female healthcare workers and highlighted its occupational health implications within a prevention, assessment, and rehabilitation framework.MethodsA descriptive cross-sectional study was conducted with 390 female healthcare workers in Turkey employed in rotating shifts. Data were collected using a Participant Information Form, the Female Sexual Function Index (FSFI), and the Sexual Quality of Life Questionnaire-Female (SQOL-F). Analyses included descriptive statistics, independent t-tests, one-way ANOVA and Multivariable linear regression.ResultsLonger professional experience, working in high-stress units (intensive care/emergency), ≥ 4 monthly night shifts, and >45 weekly working hours were significantly associated with poorer FSFI and SQOL-F scores (p < 0.05). Conversely, ≥ 32 h of rest after shifts was linked to higher scores. In multivariable analysis, FSFI and SQOL-F scores were lower among participants who reported that shift/on-call work affects sexual desire (p < 0.001).ConclusionsShift work negatively affects sexual function and sexual quality of life among female healthcare workers. These outcomes should be recognized as critical occupational health issues. Adequate rest periods, reduced night-shift frequency, and psychosocial support programs are essential preventive and rehabilitative strategies. Worker-centered institutional policies that balance service continuity with employee health may enhance both well-being and healthcare system sustainability.

BackgroundProfessional practice and care process of nurses are affected by many factors such as nurses' lifelong learning tendencies, career barriers, and job satisfaction.ObjectiveThis study aimed to evaluate the relationship between nurses' effective lifelong learning tendencies, career barriers, and job satisfaction.MethodsThis study was conducted with 1665 nurses working at a university and a city hospital in Ankara. The study data were collected using the "Personal Data Form", "Effective Lifelong Learning Scale", "Career Barriers in Nursing Scale", and "Minnesota Job Satisfaction Scale".ResultsWe found that nurses had high mean scores of effective lifelong learning and moderate mean scores of career barriers and job satisfaction. Effective Lifelong Learning Scale and Career Barriers in Nursing Scale total scores were not significantly correlated; Effective Lifelong Learning Scale correlated positively with Minnesota Job Satisfaction Scale; Career Barriers in Nursing Scale correlated negatively with Minnesota Job Satisfaction Scale.ConclusionSupporting the advancement of nurses and the nursing profession, which will strengthen the future and sustainability of health institutions, will also increase the quality of nursing care and improve patient outcomes. For this reason, we think that increasing nurses' lifelong learning skills and removing career barriers will have a positive effect on not only their job satisfaction but also patient outcomes.

BackgroundCAD (Computer Aided Design) designers spend long hours in front of visual displays, using specialized automotive design software. In addition to musculoskeletal disorders that may result from prolonged static activities, these individuals are also exposed to high mental workloads.ObjectiveThis study aims to assess the effect of office strain levels on the mental workload and musculoskeletal disorders of the design department.MethodsThis descriptive-analytical study included 48 cases, consisting of the occupation of CAD designing from the computer design department, and 48 control participants, comprised of non-computer users. It assessed musculoskeletal disorders using the CMDQ (Cornell Musculoskeletal Discomfort Questionnaire), ergonomic risk with the ROSA (Rapid Office Strain Assessment), and mental workload with the NASA-TLX (NASA Task Load Index). Data were analyzed using SPSS version 22.ResultsIn the case group, 37.5% were categorized as high risk for strain, compared to 31.25% in the control group. 27.08% of participants experienced an unacceptable level of mental workload according to NASA-TLX criteria, while only 17.71% were within the acceptable level. Significant relationships were found between office strain, musculoskeletal disorders, and mental workload, with a direct correlation between ROSA, NASA-TLX, and CMDQ scores (<0.011).ConclusionsThe most significant factors influencing office strain and mental workload among the occupation of CAD designing include ergonomic conditions in the workplace, duration of computer use, temporal demand, and the nature of job tasks. Factors such as health status, physical characteristics, and work experience are crucial in determining the intensity of mental workload and office strain.

BackgroundHealthcare providers experience a significant rate of nonfatal occupational injuries associated with their occupational duties and characteristics.ObjectiveThis study aimed to gauge occupational and physical therapists' exposure to physical risk factors and pain levels related to patient handling in outpatient rehabilitation settings.MethodsFor this observational, descriptive, and cross-sectional study design, the Workplace Ergonomics Risk Assessment (WERA) tool was used to collect real-time data, and a self-administered numeric pain intensity scale was utilized to rate pain levels.ResultsThe study included ninety-eight participants. The WERA overall final score showed that participants were exposed to moderate physical risk factors associated with Work-Related Musculoskeletal Disorders (WMSDs). Postures and repetitions of the anatomical areas were positively correlated with the use of force, vibration tools, contact stress tools, and task duration. Pain ratings showed that most of the participants experienced moderate to severe physical pain immediately after therapy sessions. A Kruskal-Wallis H test revealed a statistically significant difference in the exposure to physical risk factors in outpatient rehabilitation settings.ConclusionParticipants were exposed to moderate levels of physical risk factors and moderate to severe pain that may lead to WMSDs. Participants working in pediatric settings experienced the most significant exposure to physical risk factors. Results from this observational study were consistent with those from self-reported studies involving WMSDs from different geographical regions worldwide.
