Published: February 2025

Background Long Covid symptoms are known to have an impact on function, however, their effect on employment and the associated demographic and clinical factors are not well understood. Objective Our objectives were (1) To compare changes in employment status between those with Long Covid and those who recovered from their Covid-19 infection; and (2) To identify demographic factors, clinical factors, and occupational skill level associated with decreased employment status in those with Long Covid. Methods We conducted an electronic survey (≥12 weeks post infection) with adult residents in Laval, Quebec, Canada who tested positive for Covid-19 between March 2020 and January 2022, regarding Long Covid symptoms and their functional impact. This analysis focuses on employment status: pre-covid, prior to infection, and current, and was recorded as full-time, part-time, or not working due to illness or for other reasons. Change in employment status was categorized as no decrease or decreased. Results Among 2764 respondents, 15.6% (95% CI: 13.3–17.9) with Long Covid (versus 5.4% (95% CI: 4.2–6.5) who recovered) experienced a decrease in employment (p < 0.001). Clinical factors associated with a decrease in employment include having been hospitalized for Covid-19, having ≥1 comorbid condition prior to infection, >12 months since infection, moderate to severe decline in physical and psychological health, and decline in global health. Demographic factors and occupational skill level were not associated with a change in employment. Conclusions Persons with Long Covid are more likely to experience a decrease in employment. Research is needed to determine whether rehabilitation for people with Long Covid could improve employment levels.

Background A high level of physical activity (PAL) is necessary for the safety performance of police officers. Objective To evaluate the PAL, quality of life (QoL), and cardiorespiratory fitness (CRF) of Civil Police Officers (PO) of Brazil, in association with gender and career time. Methods We evaluated 55 PO (50.9% male), with a median age of 40 and a BMI of 25.7 kg/m2. Descriptive analysis and associations with gender and career time (G1: longer/G2: shorter) were carried out. PAL was evaluated by the IPAQ-short version. QoL and CRF were estimated using the WHOQOL and Jackson questionnaires. The chi-square test was used for associations; the odds ratio was calculated with a 95% confidence interval (95%CI) to express the strength of the association. Results There was a proportion of 72.7% (95% CI:69.0–91.0%) of active PO, with a trend for a higher proportion among women and G2 ( p = 0.07/0.08), respectively. Only 36.4% of PO (95% CI:24.0–49.0) achieved the minimum CRF required for career entry, with G1 showing a lower proportion than G2 ( p < 0.01) and a lower chance of achieving the recommended CRF (OR: 0.03 / 95% CI:0.01–0.17). The median QoL was >70 points in three of the four evaluated domains, with G2 showing higher scores than G1 in the physical domain ( p = 0.02). Conclusion More than two-thirds of the PO assessed achieved the PA recommendations for health, but the majority had a CRF below the recommended. The median QoL was good in 3 of the four WHOQOL domains. Women and those with less carrier time had higher QoL, PAL, and CRF.

Published: February 2025

Background The conventional Work Triangle principle has long been a guiding concept in kitchen design, aiming to optimize workflow and minimize workload. However, with the advent of modern appliances and evolving lifestyles, the effectiveness of the Work Triangle in addressing the diverse activities and needs of contemporary kitchens is increasingly limited. Objective This study aims to verify the validity of the Work Triangle in modern kitchen design and propose a kitchen modeling algorithm that facilitates customization based on layout and the area size from a user-centered perspective. Methods The research was conducted in two parts. In the first part, the validity of the Work Triangle was verified through the analysis of 38 actual apartment kitchen floor plans in Korea. Then the second part, a kitchen layout optimization model was developed using 0–1 integer programming to minimize the distance between kitchen appliances, incorporating the placement of modern appliances not included in the traditional Work Triangle. Results The statistical analysis of kitchen floor plans data showed that the impact of Work Triangle compliance on movement efficiency was limited, suggesting the need for customized kitchen design that reflects user behavior patterns and the placement of modern appliances and storage spaces. The model was evaluated through simulation, demonstrating its effectiveness in optimizing kitchen appliances layout. Conclusions The study emphasizes the need to consider actual usage patterns and the limitations of the Work Triangle in modern kitchen design, proposing a user-centered optimization model that enables customization based on individual cooking scenarios and lifestyles.

Published: February 2025

Background Personal Protective Equipment (PPE) is crucial for minimizing workplace hazards, and its effectiveness relies on adapting to diverse anthropometric features. Objective To establish the first 3D anthropometry database of Chilean workers. Also, this study compares 18 dimensions with the North American CAESAR three-dimensional anthropometrical scan database. Methods The research utilized three-dimensional data collected from 348 Chilean individuals, ages ranging between 19 and 68 years old. Measurements were captured with a 3D face scanner (3dMD®) following ISO/TS 16976-2 and ISO 15535 guidelines to maintain rigorous standards. Results Noticeable sexual dimorphism: Chilean males exhibit larger facial dimensions than females, such as Nose breadth and Face length, which emphasize the need for gender-specific PPE designs. Furthermore, comparisons with the CAESAR dataset revealed significant disparities among Chilean and other populations, emphasizing the importance of ethnic tailoring PPE. The implications for respiratory PPE design are substantial; variations in dimensions like Face length and Face width highlight the need for adjustable or size-specific respirators. Conclusions The study underlines the importance of considering not only gender-specific differences but also ethnic variations in PPE design. The findings emphasize the critical role of anthropometric data in developing tailored respiratory protection devices, ensuring effective workplace safety across diverse populations. The study recommends further research to validate the findings in other populations and to advocate for inclusive design practices in occupational safety.

Background Individuals with arthritis often face significant challenges in their activities of daily living and work performance, resulting in substantial effects on both their personal and professional lives. Objective This study aims to determine whether workers with arthritis within the Canadian working-age population are more or less likely to miss work, sustain injuries, or experience activity limitations compared to those without arthritis. Methods The analysis utilized data from the Canadian Community Health Survey, focusing on employed individuals over 20 from two datasets: 2015–2016 (n = 107,705) and 2017–2018 (n = 112,947). Logistic regression examined occupational health factors, while bivariate analyses via chi-squared tests (p < 0.01) filtered variables and Tukey's HSD was used for post hoc analysis (p < 0.05). Multinomial models addressed complex responses, and Wald's test compared differences between males and females. Results Individuals with arthritis (n = 27,720) were more likely to miss work, experience difficulties in daily functioning and report injury compared to their non-arthritis counterparts. Women with arthritis were also more likely to face difficulties in daily functioning and report joblessness. Men with arthritis were more likely to report work absences but less likely to report injury compared to both women and non-arthritis men. Conclusion Despite individuals with arthritis being heavily impacted in terms of functionality, there is a disconnect between accommodations provided and usage. Further research on inclusive accommodations (e.g., ergonomic tools and equipment, flexible work arrangements) and self-management strategies that can account for the problems faced by individuals with arthritis need to be established.

Background School teachers often have knee osteoarthritis due to the nature of their work. Objective To compare the effects of post-isometric exercise and piroxicam on pain and functional impairment in school teachers having knee osteoarthritis. Method A pragmatic, community-based, double-blinded, randomized clinical trial (IRCT20230202057310N4) was conducted was conducted at Muhammad Physical Therapy Clinic and Rehabilitation Center, Multan, Pakistan from September 2025 to July after approval from the Institutional Ethical Committee (). A total of 70 pre-diagnosed osteoarthritis patients were randomly assigned to two groups after enrollment using the lottery method. Patients of Group A were treated with post-isometric exercises for 12 weeks (3 sessions per week and each session lasted for 45 min), while those in Group B were given piroxicam (given orally 20 mg twice a day for 12 weeks). At baseline and the 18th session, pain and daily activities were measured using the Pain Catastrophizing Scale (PCS), the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scale, and Numerical Pain Rating Scale (NPRS), biochemical (ESR, CRP, and WBCs) and radiological (X-rays) parameters were evaluated. The data was analyzed by using SPSS-23. The independent t-test compared differences between two unrelated groups while the paired t-test assessed differences within the same group. P-value <0.005 was considered significant. Results Out of 70 patients, 68 patients were assessed and there were 46 females and 21 males. The results showed a highly significant improvement in flexion (p = 0.001), WOMAC ADLs (p = 0.001), WOMAC stiffness (p = 0.004), PCS (p = 0.001) in group-A than group-B. Similarly, there was a highly significant improvement in NPRS (p = 0.001), WOMAC pain (p = 0.001), WBCs % (p = 0.002), ESR (p = 0.002) and CRP (p = 0.003) in group-B than group-A, underscoring the effectiveness of the post-isometric exercises. Conclusion These findings suggest that post-isometric exercises could be a more beneficial treatment option than piroxicam for knee osteoarthritis. The practical implications of this research are significant, as it demonstrates that post-isometric exercises not only enhance functional results but also reduce pain severity, offering a promising alternative to traditional medication.

Published: February 2025

Background It is crucial to understand perceptions on exposure to air pollution for designing targeted interventions, raising awareness, and fostering measures to mitigate occupational health risk and improve the overall health outcomes. Objective This study aims at understanding the perception of the practitioners of various occupations vis-à-vis the general public on occupational exposure to air pollution (OEAP). Methods The four-step assessment we carried out involved recording perceptions via Google forms and in-person surveys, conducting statistical analyses (descriptive statistics, regression analyses and tests of significance), analyses using Odds Ratio (OR) and comparing the results with risk perception theories. Results 712 respondents across the country participated in the survey and 57% of them perceived that they work in a moderately healthy environment. Test of significance showed that gender and age do not significantly affect the perception. However, factors like education, income level, locality, and location of the job significantly influenced the perception. Linear regression analysis showed that ambient air quality is a significant predictor of workplace air quality perception. The OR indicated strong dependence of workers’ perception on the actual OEAP. Regarding the exposure associated with a profession, the perception of the practitioners of that profession and the public matched for those professions where the exposures were expected to be high but deviated significantly when the profession had relatively lower exposure to pollution. Conclusion The perception of risks compared to actual risks will serve as the foundation for developing awareness and sensitization programmes focused on occupational risk.

Published: February 2025

Background This paper focuses on patient-initiated workplace violence (referred to WPV hereafter) towards healthcare workers in long-term care (LTC) and mental health and substance use (MHSU) care settings. While an extensive body of evidence has thoroughly examined WPV, our understanding of what takes place immediately before or during a violent incident, known as ‘on-the-spot’ experiences is limited. Objective This study examined (a) ‘on-the-spot’ experiences, (b) contributing factors, and (c) warning signs of impending WPV using the experiences of healthcare worker victims and witnesses and healthcare attendees in LTC and MHSU. Methods The study was conducted in one LTC home and two MHSU units in British Columbia, Canada. In-depth semi-structured virtual interviews were conducted with 17 participants from June to September 2023. Workplace Health Indicator Tracking and Evaluation (WHITE) data included 38 WPV incidents occurring between January 2022 to March 2023. Data were analyzed using thematic analysis. Results Six participants (35%) identified as both victims and witnesses of WPV, four participants (24%) as only victims, and five participants (29%) as only witnesses. Contributing factors to WPV encompassed two main themes and their subthemes: (1) patient/resident factors (cognitive impairment and neurodevelopmental conditions); (2) healthcare factors (lack of continuity of care across healthcare, community and family, care provision, approaches and skills in interactions with patients/residents, access to safety tools and security personnel, and unmet needs and workload and human resource challenges). Conclusion WPV may be reduced through access to specialized care, adoption of team-based care and person-centered care approaches, addressing resource constraints, and offering context-specific training.

Published: February 2025

Background Despite national recommendations and decades of literature highlighting the importance of faculty wellness, gaps at academic medical centers remain. Multilevel wellness initiatives are necessary to create change and optimally support academic faculty. Objective The purpose of this study is to examine faculty perceptions of factors contributing to lack of wellness and proposed solutions in the context of current resources at our academic medical center in the Mid-Atlantic region of the United States. Methods The Georgetown University Medical Center Faculty Development Committee created a Wellness Task Force in response to a charge by leadership. The 11-member Task Force included faculty members from different disciplines: psychiatry, neurology, family medicine, pediatrics, nursing and oncology. Data collection occurred September 2021 to January 2022. Interviews and focus groups elicited faculty input on 1) factors that contribute to and detract from wellness and 2) strategies to enhance wellness within our academic medical center. Results Faculty described individual and organizational factors contributing to lack of wellness: challenges with balance; lack of connection, autonomy, resources and feeling valued; communication; culture; attention to diversity, equity, and inclusion; leadership; and workload. Proposed solutions included a comprehensive, centralized and consistent plan; culture change; incentives; increased autonomy, feelings of value, and resources. Conclusions Wellness as a budgetary priority and strategic initiative remains a critical goal for academic medical centers. Faculty perceptions of factors contributing to lack of wellness and proposed solutions underscore and add to national recommendations.

Background: The distal tibiofibular syndesmosis (DTS) is crucial for maintaining ankle stability and distributing stress in the ankle joint. However, the in vivo kinematics of the DTS during high-impact activities remain unknown. This study aims to explore these kinematics and investigate the influence of additional trunk load using a high-speed dual fluoroscopy imaging system (DFIS). It was hypothesized that the maximum lateral translation of the DTS would not exceed the diagnostic threshold, and the range of motion (ROM) would increase with the addition of load. Methods: This study included 14 healthy participants. Magnetic resonance imaging (MRI) was used to create 3-dimensional models of the distal tibia and fibula. High-speed DFIS was employed to capture continuous fluoroscopic images of the DTS while participants performed single-leg landing jumps. A weighted vest was used to introduce additional load. DFIS data and 3D models were imported into virtual environment software to obtain kinematic data. A 1-way analysis of variance was conducted to compare 3-dimensional 6 degree-of-freedom kinematics and the joint’s ROM before and after adding trunk load. Results: The primary rotational movements of the DTS after ground contact were eversion and external rotation, whereas translational movements included lateral and downward translation. After adding additional load, the DTS showed a significantly greater maximum extension angle (2.70 ± 0.56 degrees vs 3.17 ± 0.59 degrees, P = .038) and flexion-extension ROM (2.74 ± 0.61 degrees vs 3.32 ± 0.83 degrees, P = .044) compared to preload conditions. The maximum internal rotation angle (0.25 ± 0.73 degrees vs 1.51 ± 0.86 degrees, P < .001) and internal-external rotation ROM (-2.09 ± 1.39 degrees vs 3.88 ± 1.10 degrees, P = .004) of the DTS were significantly greater after adding load. Conclusion: During single-leg landing, the primary movements of the DTS involve eversion and external rotation. With additional loading, the rotational angles of the DTS increase. Clinical Relevance: The distal tibiofibular syndesmosis increases its rotational motion angle to accommodate higher loads.

Published: February 2025

Objectives Multiple myeloma (MM) is a hematologic malignancy comprising approximately 10% of all blood cancers. Patients with MM are at risk for disseminated intravascular coagulation (DIC), a serious complication characterized by systemic coagulation activation, leading to microthrombi, organ dysfunction, and severe bleeding. This study aims to investigate the incidence of DIC among MM patients and identify risk factors associated with DIC development. We also sought to develop a predictive formula for assessing DIC risk. Methods A retrospective analysis was conducted on MM patients. Logistic regression analysis was used to identify factors significantly associated with DIC. The predictive power of the logistic regression model was evaluated using receiver operating characteristic (ROC) curve analysis. Results The incidence of DIC among hospitalized MM patients was 16.8%. Significant factors identified by logistic regression analysis included prothrombin time (PT), fibrin degradation products (FDP), and D-dimer levels. ROC curve analysis indicated that the predictive model had strong discriminatory power, with an area under the curve (AUC) of 0.927. A predictive formula for the probability of DIC occurrence was developed based on the logistic regression model. Conclusions The predictive formula developed in this study offers a tool for early identification of MM patients at high risk of DIC. While the model demonstrates strong predictive capability, further validation and refinement are required to improve its accuracy and clinical application.
