Raynaud's phenomenon in the feet of Arctic open-pit miners

The literature on Raynaud's phenomenon (RP) in the feet is scarce, especially in the occupational setting. The primary aim of our study was to investigate the occurrence of RP in the feet of miners. As part of the MineHealth project, written surveys and clinical examinations were completed by 260 Arctic open-pit miners working in northern Sweden and Norway (participation rate 53.6%). Data on RP were collected using standardised colour charts and questionnaire items. Clinical examination included assessing the perception of vibration and pain in both feet. There were eight women and three men who reported RP in the feet. Four also had RP in their hands but none acknowledged any first-degree relatives with the condition. Nine reported exposure to foot-transmitted vibration and one to hand-arm vibration. Seven showed signs of neurosensory injury in the feet. To conclude, the occurrence of RP in the feet of miners was 4.4%. Most cases with RP in the feet did not report the condition in the hands and were exposed to vibration transmitted directly to the feet. There were no reports of a hereditary component. Most cases with RP in the feet also had clinical findings suggestive of peripheral neuropathy in the feet.

Effects of a combined aerobic and core stabilization exercise training program on functional capacity, pain, and health-related quality of life in hemodialysis and kidney transplant patients

BACKGROUND

Chronic kidney disease (CKD) poses a significant public health challenge globally while impacting patients' physical function and quality of life. Addressing the issues of physical inactivity and pain management is essential during treatment to improve health-related quality of life. The present study investigated the effect of an aerobic training program with core stabilization exercises for hemodialysis (HD) patients on a transplant waiting list and renal transplant (RTx) patients.

METHODS

A total of 45 patients with CKD were included in the 12-week study: 25 patients receiving HD (12 HD treatment group, 13 HD control group) and 20 patients with RTx (9 RTx treatment group, 11 RTx control group). Functional capacity was measured using the 6-min walk test, pain was measured using the visual analog scale, and health-related quality of life was measured using the Kidney Disease Quality of Life-Short Form 12 questionnaire. Nonparametric statistical tests were performed at a significance level of 0.05.

RESULTS

Both the HD and RTx treatment groups showed significantly reduced times for the 6-min walking test (p = 0.002 and p = 0.008, respectively), significantly reduced pain severity (p = 0.002 and p = 0.008, respectively), and significantly improved quality of life scores (p = 0.006 and p = 0.041, respectively) by the end of the study compared with control groups.

CONCLUSION

Based on the results, structured exercise programs could be effective therapies in CKD management. Therefore, health providers should promote their integration into routine care practices to enhance patient outcomes and well-being.

Cognitive-behavioral stress management relieves anxiety, depression, and post-traumatic stress disorder in parents of pediatric acute myeloid leukemia patients: a randomized, controlled study

OBJECTIVES

Cognitive-behavioral stress management (CBSM) is an effective psychological intervention to relieve psychological and symptomatic distress. This study aimed to investigate the effect of CBSM in anxiety, depression, and post-traumatic stress disorder (PTSD) in parents of pediatric acute myeloid leukemia (AML) patients.

METHODS

Totally, 56 pediatric AML patients and 100 parents were randomized into the CBSM group (28 patients and 49 parents) and the normal control (NC) group (28 patients and 51 parents) to receive corresponding interventions for 10 weeks. The questionnaire scores were assessed at month M0, M1, M3, and M6.

RESULTS

In parents of pediatric AML patients, self-rating anxiety scale score at M1 (p = 0.034), M3 (p = 0.010), and M6 (p = 0.003), as well as anxiety at M3 (p = 0.036) and M6 (p = 0.012) were decreased in the CBSM group versus the NC group. Self-rating depression scale score at M3 (p = 0.022) and M6 (p = 0.002), as well as depression at M6 (p = 0.019) were declined in the CBSM group versus the NC group. Symptom checklist-90 (a psychotic status questionnaire) score at M3 (p = 0.031) and M6 (p = 0.019) were declined in the CBSM group versus the NC group. Regarding PTSD, the impact of the events scale-revised score at M3 (p = 0.044) and M6 (p = 0.010) were decreased in the CBSM group versus the NC group. By subgroup analyses CBSM (versus NC) improved all outcomes in parents with anxiety at M0 and depression at M0 (all p < 0.050), but could not affect the outcomes in parents without anxiety or depression at M0 (all p > 0.050).

CONCLUSION

CBSM reduces anxiety, depression, and PTSD in parents of pediatric AML patients.

"It takes a lot of sisu to get through it"- managerial experiences of facing adversities during pandemic

PURPOSE

Sisu refers to extraordinary internal strength in the face of adversities. Although originally a Finnish concept, it can be a universally useful concept for studying managerial well-being and performance during difficult or even emergency periods. Previous research on sisu categorizes it into beneficial and harmful sisu and suggests that these two dimensions of sisu are useful when studying determination and resoluteness in crisis situations. This study applies the concept of sisu to examine managers' well-being in times of crisis.

METHODOLOGY

Interviews were conducted with 15 managers in the hotel, manufacturing and retail industries in Finland.

RESULTS

The beneficial effects of sisu seem to dissolve when it is used too often. The study also highlighted the paradoxical tension involved in the decision to stop or continue actions in a difficult situation and contributes to sisu research by discussing collective sisu.

CONCLUSION

The results of this study suggest that beneficial sisu helps to overcome adversity, while harmful sisu causes distortions in thinking that are detrimental to managers. Understanding one's own tendency towards beneficial or harmful sisu in difficult situations can help in managerial work. Collective sisu is an excellent resource for overcoming difficult situations in workplaces.

"I feel like it should be but I know it's really not": exploring physical fitness priorities at the correctional training program in Canadian federal corrections

The correctional training program (CTP), composed of three stages, includes a 14 week in-person component that Correctional Officer Recruits (CORs) must complete prior to their employment as a federal Correctional Officer (CO) for Correctional Service Canada (CSC). The CTP prepares recruits for a plethora of CO responsibilities, some dependent on physical fitness, such as responding to codes being called, physical altercations, or violent situations. Unlike other public safety positions (e.g. policing, border services, or coast guard) CSC does not require occupational fitness testing. In the current article, we use data from a multiyear longitudinal study of federal COs from across Canada to unpack how CORs manage physical fitness expectations at CTP; CSCs' expectations of COR physical fitness; and outline what types of physical fitness (e.g. weightlifting, cardiovascular, self-defence) are taught, thus valued most, during CTP. We situate the voices of CORs regarding physical fitness within the broader "body" literature and discuss policy recommendations tied to physical fitness, specifically COs' interest in reinstating pre-employment physical fitness screening.

Depicting occupational trauma concepts impacting nurse well-being during the COVID-19 pandemic

PURPOSE

The purpose of this concept delineation was to differentiate similar concepts impacting nurse well-being during the COVID-19 pandemic, including: compassion fatigue, burnout, moral injury, secondary traumatic stress, and second victim.

METHODS

A total of 63 articles were reviewed for concept delineation. Morse's (1995) approach to concept delineation was utilized to analyse the articles.

RESULTS

Concepts were described interchangeably but were found to present themselves in a sequence. A nurse may experience moral injury, leading to a second victim experience, synonymous with secondary traumatic stress, then compassion fatigue and/or burnout that can be acute or chronic in nature. An Occupational Trauma Conceptual Model was created to depict how these concepts interact based on concept delineation findings.

CONCLUSION

Nurses are experiencing long-lasting occupational trauma and future intervention research should centre on optimizing nurse well-being to ensure the sustainability of nursing profession.

Towards a knowledge-based decision support system to foster the return to work of wheelchair users

Accidents at work may force workers to face abrupt changes in their daily life: one of the most impactful accident cases consists of the worker remaining in a wheelchair. Return To Work (RTW) of wheelchair users in their working age is still challenging, encompassing the expertise of clinical and rehabilitation personnel and social workers to match the workers' residual capabilities with job requirements. This work describes a novel and prototypical knowledge-based Decision Support System (DSS) that matches workers' residual capabilities with job requirements, thus helping vocational therapists and clinical personnel in the RTW decision-making process for WUs. The DSS leverages expert knowledge in the form of ontologies to represent the International Classification of Functioning, Disability, and Health (ICF) and the Occupational Information Network (O*NET). These taxonomies enable both workers' health conditions and job requirements formalization, which are processed to assess the suitability of a job depending on a worker's condition. Consequently, the DSS suggests a list of jobs a wheelchair user can still perform, exploiting his/her residual abilities at their best. The manuscript describes the theoretical approach and technological foundations of such DSS, illustrating its development, its output metric, and application. The developed solution was tested with real wheelchair users' health conditions provided by the Italian National Institute for Insurance against Accidents at Work. The feasibility of an approach based on objective data was thus demonstrated, providing a novel point of view in the critical process of decision-making during RTW.

Ethical challenges from a problem-solving intervention with workplace involvement: a qualitative study among employees with common mental disorders, first-line managers, and rehabilitation coordinators

PURPOSE

This study aims to explore ethical challenges potentially arising from a problem-solving intervention with workplace involvement (PSI-WPI) in primary health care (with first-line manager involvement) for employees on sickness absence due to common mental disorders.

METHODS

A qualitative design guided by the theoretical framework for systematic identification of ethical aspects of healthcare technologies. Semi-structured interviews were performed with coordinators (n = 6), employees (n = 13), and first-line managers (n = 8). Reflexive thematic analysis was used to analyse and interpret themes.

RESULTS

A main theme was identified "the workplace and healthcare hold different organizational value logics" and four sub-themes: "the PSI-WPI challenged the organizational goals and values of the workplace and healthcare", "the PSI-WPI challenged organizational values on fairness", "the PSI-WPI challenged the professional roles of first-line managers and rehabilitation coordinators" and "the PSI-WPI introduced a need for the employee to juggle the employee and patient roles".

CONCLUSION

Different organizational value logics, values, and goals can introduce ethical challenges. We advise clarifying stakeholders' roles and preparing employees and managers for the return to work process by providing sufficient information. The ethical challenges and suggested measures to minimize them, should be considered when planning return to work interventions that involve several stakeholders.

Virtual fit assessment of U.S. army body armor using NASA spacesuit techniques

Fit and accommodation are critical design goals for a body armor system to maximize Soldiers' protection, comfort, mobility, and performance. The aim of this study is to assess fit and accommodation of body armor plates for the US Army. A virtual fit assessment technique, developed, validated, and deployed by NASA for spacesuit design, was adopted for this work. Specifically, 3D manikins of the Soldier population were overlaid virtually with geometrically similar surrogates of the armor plates. Trained subject matter experts with the US Army and NASA manually assessed the fit of the armor plates to manikins using a computer visualization tool and selected the appropriate plate size and position. A prediction model was built from the assessment data to predict the plate size from an arbitrary body shape and the resultant patterns of body-to-plate contact were quantified. The outcome indicated a unique trend of the plate sizes covarying with anthropometry. More pronouncedly, when the overlap between the body tissue and armor plate was quantified, female Soldiers are likely to experience a 25 times larger body-to-plate contact volume and 6.5 times larger contact depth than males on average, due to sex-based anthropometric differences. Overall, the prediction model and contact patterns provided key metrics for virtual body armor fit assessments, of which the locations, patterns, and magnitudes can help to improve sizing and fit of body armor systems, as previously demonstrated for NASA spacesuit design.

Return to work in persons with persistent postconcussion symptoms: a survey study examining the perspectives of employees and managers

OBJECTIVE

To examine challenges in return to work (RTW) for persons with persistent postconcussion symptoms (PPCS) experienced by the affected employees and their managers.

METHODS

A survey of employees (S-E) and two surveys of managers (S-M1, S-M2) executed 4 months apart to capture the time perspective. Inclusion: Adults aged 18-66 with PPCS > 4 weeks, employed at the time of mTBI who returned to work within the previous year. Managers involved in their RTW process.

OUTCOME MEASURES

Work status, working hours, work functioning (Work Role Functioning Questionnaire, WRFQ), work productivity.

RESULTS

Ninety-two employees and 66 managers were recruited. Three-fourths of the employees had returned to work but only one-third worked under similar conditions. Weekly working hours decreased from 36,3 hours (SD = 10,5) before mTBI to 17,6 hours (SD = 9,7). Employees had difficulties with tasks 43% of time (WRFQ). They needed more breaks, struggled with multitasking and work speed. About 65.9% experienced affected work productivity. Managers reported lack of knowledge and difficulties assessing the number of working hours and suitable tasks.

CONCLUSIONS

Most employees returned to work but only a minority worked under similar conditions as before mTBI. Employees and managers struggled to estimate workload. The affected employees and their workplaces need a long-term RTW support.

Brick kiln pollution and its impact on health: A systematic review and meta-analysis

Brick kiln emissions adversely affect air pollution and the health of workers and individuals living near the kilns; however, evidence of their impacts remains limited. We conducted a systematic review of brick kiln pollution (emissions, source contributions and personal exposures) and its effects on health. We extracted articles from electronic databases and through manual citation searching. We estimated pooled, sample-size-weighted means and standard deviations for personal exposures by job type; computed mean emission factors and pollutant concentrations by brick kiln design; and meta-analyzed differences in means or proportions for health outcomes between brick kiln workers and controls or for participants living near or far away from kilns. We identified 104 studies; 74 were conducted in South Asia. The most evaluated pollutants were particulate matter (PM; n = 48), sulfur dioxide (SO2; n = 24) and carbon monoxide (CO; n = 22), and the most evaluated health outcomes were respiratory health (n = 34) and musculoskeletal disorders (n = 9). PM and CO emissions were higher among traditional than improved brick kilns. Mean respirable silica exposures were only measured in 4 (4%) studies and were as high as 620 μg/m3, exceeding the NIOSH recommended exposure limit by a factor of over 12. Brick kiln workers had consistently worse lung function, more respiratory symptoms, more musculoskeletal complaints, and more inflammation when compared to unexposed participants across studies; however, most studies had a small sample size and did not fully describe methods used for sampling or data collection. On average, brick kiln workers had worse health outcomes when compared to unexposed controls but study quality supporting the evidence was low. Few studies reported silica concentrations or personal exposures, but the few that did suggest that exposures are high. Further research is needed to better understand the relationship between brick kiln pollution and health among workers, and to evaluate exposure mitigation strategies.

A New Mouse Model for Usher Syndrome Crossing Kunming Mice with CBA/J Mice

BACKGROUND

Previously, we discovered a strain of Kunming mice, referred to as the KMush/ush strain, that exhibited notably abnormal electroretinogram (ERG) readings and elevated thresholds for auditory brainstem responses (ABRs), which resembled the characteristics of Usher Syndrome (USH). We successfully identified the pathogenic genes, Pde6b and Adgrv1, after KMush/ush crossbred with CBA/CaJ mice, referred to as CBA-1ush/ush, CBA-2ush/ush or CBA-2ush/ush. In this investigation, we crossbred KMush/ush and CBA/J mice to establish novel recombinant inbred lines and analysed their phenotypic and genotypic characteristics.

METHODS

ERG readings, ABR testing, fundus morphology, histological examination of the retina and inner ear, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis, western blotting, DNA sequence analysis and behavioural experiments were performed to assess the phenotypes and genotypes of the progeny lines.

RESULTS

No obvious waveforms in the ERG were detected in F1 hybrid mice while normal ABR results were recorded. The F2 hybrids, which were called J1ush/ush or J2ush/ush, exhibited segregated hearing-loss phenotypes. J1ush/ush mice had a retinitis pigmentosa (RP) phenotype with elevated ABR thresholds, whereas J2ush/ush mice exhibited only the RP phenotype. Interestingly, J1ush/ush mice showed significantly higher ABR thresholds than wild-type mice at 28 days post born (P28), and RT-qPCR and DNA-sequencing analysis showed that Adgrv1 gene expression was significantly altered in J1ush/ush mice, but histological analysis showed no significant structural changes in the organ of Corti or spiral ganglia. Further elevation of ABR-related hearing thresholds by P56 manifested only as a reduced density of spiral ganglion cells, which differed significantly from the previous pattern of cochlear alterations in CBA-2ush/ush mice.

CONCLUSIONS

We successfully introduced the hearing-loss phenotype of inbred mice with USH into CBA/J mice, which provides a good animal model for future studies on the important physiological roles of the Adgrv1 gene in inner-ear structure and for therapeutic studies targeting Adgrv1-mutated USH.

The use of role-play in the learning of medical terminology for online and face-to-face courses

Student engagement while learning a new, unfamiliar vocabulary is challenging in health science courses. A group role-play activity was created to teach students medical terminology and learn why its correct usage is important. This activity brought engagement and relevance to a topic traditionally taught through lecture and rote memorization and led to the development of an undergraduate and a stand-alone introductory course to teach students medical terminology. The undergraduate course was designed to be a fully online medical terminology course for health science students and a face-to-face course for first-year dental students founded in active learning and group work. The course's centerpiece learning activity focused on using published case studies with role-play. In this group activity, students are challenged to interpret a published patient case study as one of the members of a healthcare team. This course models the group work inherent in modern health care to practice building community and practicing professional skills. This approach gives students the capacity to work asynchronously in a team-based approach using our learning management system's wiki tool and requires students to take responsibility for their learning and group dynamics. Students practice identification, writing, analyzing, and speaking medical terms while rotating through the roles. Students in both classes self-reported a 92% to 99% strong or somewhat agreement using a five-point Likert scale that the course pedagogy was valued and helpful in their learning of medical terminology. Overall, this method has proven to be an engaging way for students to learn medical terminology.NEW & NOTEWORTHY Role-play can engage students and encourage learning in identification, pronouncing, writing, and understanding medical terminology in multiple course formats.

School-Based Occupational Therapists' Roles Supporting Transitions Into and Throughout Kindergarten to Grade 12: A Scoping Review

IMPORTANCE

Large educational transitions occur when students enter and exit school or move between grades or divisions within the kindergarten to Grade 12 (K-12) school system. For students with disabilities, the quality of large educational transitions affects academic and postschool outcomes, which is germane to school-based occupational therapists.

OBJECTIVE

To explore the school-based occupational therapy literature to describe the roles of occupational therapists in supporting large educational transitions and to identify relevant terminology.

DATA SOURCES

We searched six databases (CINAHL, EMCare, Embase, ERIC, MEDLINE, and PsycINFO) for peer-reviewed publications in English with no date limitations.

STUDY SELECTION AND DATA COLLECTION

We included articles focused on children and youth with disabilities and school-based occupational therapy services supporting large transitions within K to 12 education. Using directed content analysis, we reported on publication characteristics, occupational therapy roles, and terminology.

FINDINGS

We included 46 publications spanning 37 yr that addressed transitions into school (n = 3), within K to 12 grades or divisions (n = 10), or to exit secondary education (n = 33). Occupational therapists assumed many roles in supporting large transitions, some much more frequently than others; 125 transition terms were used across included articles with few terms explicitly defined.

CONCLUSIONS AND RELEVANCE

School-based occupational therapists' involvement in educational transitions is extensive, with potential for expansion. Consistency in terminology would support future research and practice. Plain-Language Summary: A large educational transition occurs when students move between a school, grade, or division as part of their K to 12 education. For students with disabilities, the quality of a large educational transition affects their academic and postschool outcomes. This review provides an understanding of how school-based occupational therapists support educational transitions for youth with disabilities. The review found that occupational therapists took on many roles, with the potential for expanding their roles. The review also identified 125 transition terms that were used across the literature review and found that few terms were explicitly defined. Consistency in terminology would support future research and expanded occupational therapy practice in this area.

Stress, burnout and coping among nurses working on acute medical wards and in the community: A quantitative study

BACKGROUND

Psychological distress can cause burnout, which affects mental and physical well-being. It is important to identify factors associated with psychological distress and physical discomfort and how nurses deal with these problems.

AIM

The aim was to investigate distress, burnout and coping among community nurses (CN) and hospital nurses (HN).

APPROACH AND METHODS

In this cross-sectional study, 409 nurses completed three questionnaires: Perceived Stress Scale (PSS), Copenhagen Burnout Inventory (CBI) and Ways of Coping (WOC).

FINDINGS

Participants younger than 40 demonstrated significantly more distress and burnout than those older than 40 years. Participants who had moderate and high distress on the PSS were significantly more at risk for experiencing personal, work-related and patient-related burnout. A significant positive correlation was found between distress and behavioural escape-avoidance, cognitive escape-avoidance and distancing. Significant positive correlations were also seen between all the subscales of the CBI and behavioural escape-avoidance, cognitive escape-avoidance and distancing. Positive significant correlation was also obtained between staff resources and distress and personal-related and work-related burnout. Negative correlation was demonstrated between staff resources and patient-related burnout. Participants with longer work experience were less likely to report moderate or high distress, and those who scored higher on personal burnout and behavioural escape-avoidance were more likely to have moderate or high distress.

CONCLUSION

The results of this study call for increased attention to the younger generation in the nursing profession. The results also validate the need to investigate further the correlation between distress, burnout and coping and how these issues might influence each other among nurses working in the community and hospitals. Findings should be taken with precaution, they do not describe in detail what underlying factors contribute to distress and discomfort found in this study, they do, however, indicate certain coping strategies nurses use to deal with distress and burnout.

Prediction model of subacromial pain syndrome in assembly workers using shoulder range of motion and muscle strength based on support vector machine

Subacromial pain syndrome (SAPS) is the most common upper-extremity musculoskeletal problem among workers. In this study, a machine learning model was built to predict and classify the presence or absence of SAPS in assembly workers with shoulder joint range of motion (ROM) and muscle strength data using support vector machine (SVM). Permutation importance was used to determine important variables for predicting workers with or without SAPS. The accuracy of the support vector classifier (SVC) polynomial model for classifying workers with SAPS was 82.4%. The important variables in model construction were internal rotation and abduction of shoulder ROM and internal rotation of shoulder muscle strength. It is possible to accurately perform SAPS classification of workers with relatively easy-to-obtain shoulder ROM and muscle strength data using this model. In addition, preventing SAPS in workers is possible by adjusting the factors affecting model building using exercise or rehabilitation programs.Practitioner summary: This study aimed to create a machine learning model that can predict and classify SAPS using shoulder ROM and muscle strength and identify the variables that are of high importance in model construction. This model could be used to predict or classify workers' SAPS and manage or prevent SAPS.

Parents' work demands on next day's cortisol awakening response - the moderating role of family-to-work conflict

BACKGROUND

Constant availability, overtime and feeling overwhelmed by work can impact employees' wellbeing and their biological stress responses. Especially working parents often struggle to balance the demands of their work and family life and were found to be distracted from their work due to family responsibilities. The Family-to-Work Conflict (FWC) indicates the extent to which participating in work is made difficult by family demands. Recent studies have found associations between FWC and biological outcomes such as the Cortisol Awakening Response (CAR), a measure of an individual's Hypothalamic-Pituitary-Adrenal (HPA)-axis activity. This diary study investigates the effect of parental work demands on next day's cortisol response as well as the moderating role of FWC and the mediating role of fatigue.

METHODS

Over the course of five consecutive days (from Monday to Friday), 168 observations were made on a total of 42 parents. Participants had at least one child and worked a minimum of 20 hours per week. Salivary cortisol samples were obtained immediately, 15 and 30 minutes after awakening each day. Work demands, FWC and fatigue were assessed using standardized questionnaires. Within-person effects were examined using multilevel modeling and mediation analyses.

RESULTS

Our results indicate that there are no main effects of work demands on next day's cortisol response. The multilevel analysis revealed that FWC predicts lower wakening cortisol levels and confirmed FWC as an increasing moderator between work demands and next day's HPA-axis activity. Further, work overload was found to increase fatigue, which in turn leads to higher CAR on the following day. This indicates that fatigue mediates the relationship between work demands and CAR. Our findings add to a growing body of research demonstrating further predictors for HPA-axis activity and emphasise the importance of considering family related demands when investigating biological outcomes for working parents.

Autostereoscopic 3D viewing can change the dimensions of the crystalline lens in myopes

PURPOSE

Autostereoscopic displays have become increasingly common, but their impact on ocular dimensions remains unknown. We sought to identify changes in the crystalline lens dimensions induced by autostereoscopic three-dimensional (3D) viewing.

METHODS

Forty young adults (age: 22.6 ± 2.0 years, male/female: 15/25) were consecutively enrolled and randomly divided into two groups (3D and two-dimensional [2D] viewing groups) to watch a 30-min movie clip displayed in 3D or 2D mode on a tablet computer. The lens thickness (LT), diameter, curvature, decentration and tilt were measured with anterior segment optical coherence tomography under both non-accommodating (static) and accommodating conditions.

RESULTS

In the static condition, the LT decreased by 0.03 ± 0.03 mm (p < 0.001) and the anterior radius of curvature (ARC) increased by 0.49 ± 0.59 mm (p = 0.001) post-3D viewing. In contrast, following 2D viewing, the ARC decreased by 0.23 ± 0.25 mm (p = 0.001). Additionally, the increase in the steep ARC post-3D viewing was greater in high-myopic eyes than low to moderate myopic eyes (p = 0.04). When comparing the accommodative with the static (non-accommodative) condition, for 3D viewing the lens decentration decreased (-0.03 ± 0.05 mm, p = 0.02); while for 2D viewing, the posterior curvature radius (-0.14 ± 0.20 mm, p = 0.006) and diameter (-0.13 ± 0.20 mm, p = 0.01) decreased.

CONCLUSIONS

Viewing with the autostereoscopic 3D tablet could temporally decrease the thickness and curvature of the lens under non-accommodating conditions. However, its long-term effect requires further exploration.

Transport and mining machinery cabins' ergonomic evaluation as a path to its redesign

Transport and mining machinery cabins are still not well adapted to their users, while checklists for their evaluation are not common in the literature. This article proposes a new checklist for ergonomic evaluation and tests its universality empirically with a sample of 96 transport and mining machine operators. The objective of the article is two-fold. First, the article checks whether there are anthropometric dimension differences between different machines' operators. Second, statistical significance testing regarding items in the proposed checklist is performed to check its universality. Significant differences have not been found between anthropometric dimensions of transport and mining machine operators. Group comparisons prove that mining machines have better ergonomics characteristics of the chair, manual controls and vision field. The recommendation for crane designers is to examine mining machines solutions and analyze the possibility of adapting these solutions, due to anthropometric fit. Wide usage of the checklist is recommended.

Prevalence and Biopsychosocial Factors Associated With a Current Episode of Low Back Pain Among Adults With a Previous History of Low Back Pain: A Cross-sectional Study of Market Traders in an African Population

Low back pain (LBP) is the leading cause of years lived with disability globally, with Nigeria having one of the greatest burdens. A current episode of LBP is important in Nigeria, but the associated factors are unknown. This cross-sectional study investigated the prevalence, biomechanical, and psychosocial factors associated with a current episode of LBP among 700 adult market traders with previous LBP in an urban Nigerian population. Descriptive, bivariate, and multivariate analyses were conducted. The prevalence of a current episode of LBP was 76.4%. Factors associated with an increased risk of a current episode of LBP in a decreasing order of importance were exposure to biomechanical factors (aggregate [total] score) (odds ratio [OR] = 1.535; 95% confidence interval [CI] = 1.398-1.685); anxiety (OR = 1.182; 95% CI = 1.089-1.282); fear-avoidance beliefs (physical activity) (OR = 1.139; 95% CI = 1.029-1.261); fear-avoidance beliefs (work) (OR = 1.105; 95% CI = 1.047-1.165); while factors associated with a reduced risk of a current episode of LBP were ability to take breaks in the job in addition to scheduled breaks (OR = .430; 95% CI = .240-.773) and ability to control the order and pace of tasks (OR = .477; 95% CI = .236-.965). Occupational biomechanical and psychosocial factors were associated with a current episode of LBP in logistic regression models explaining 52.7% and 73.1% of the variation in a current episode of LBP. Occupational biomechanical factors, particularly handling large and bulky objects at arm's length and kneeling and squatting, produced the greatest risk of a current episode of LBP. PERSPECTIVE: Occupational biomechanical factors, occupational psychosocial factors, and personal psychosocial factors such as anxiety and fear-avoidance beliefs are associated with a current episode of LBP in Nigeria. Pragmatic public health and occupational health initiatives that modify exposure to these factors may be required in Nigeria.

An Intervention to Improve Mental and Physical Health of Undergraduate Nursing Students

BACKGROUND

Nursing students experience poorer mental and physical health relative to students in other health-related disciplines and young adults of similar age outside post-secondary school. Compromised mental and physical health has numerous negative impacts on nursing students and can result in burnout and development of chronic diseases.

PURPOSE

To determine whether an asynchronous online yoga intervention would improve mental and physical health of students.

METHODS

An asynchronous online 6-week yoga intervention was carried out between January and December 2021, using a pre/post design. Participants' symptoms of depression, anxiety, stress, and self-compassion were assessed using the Depression, Anxiety, and Stress Scale and Self-Compassion Scale and core endurance was assessed using the Mackenzie Core Endurance Test prior to commencement and at the conclusion of the program.

RESULTS

Of 114 participants, 68 completed the online program and pre and post measures showed that the mean depression, anxiety, stress, self-compassion and core endurance scores improved significantly (p<0.001) between baseline and study completion.

CONCLUSION

A six-week virtual yoga program significantly improved mental and physical health of undergraduate nursing students. Targeted modifications to the yoga program might enhance participant retention.

'Wait…, let me tell you, if I worked for a boss, I would be on sick leave': A Qualitative Study of Self-Employed Workers in Physically Demanding Jobs in the Netherlands

PURPOSE

The purpose of this study was to explore the perspectives of self-employed workers with a physically demanding job on work participation.

METHODS

We interviewed self-employed workers with a physically demanding job, using semi-structured interviews, which were audio recorded. The main topic addressed was the workers' health in relation with their work participation, work demands, and preventive measures. The interviews were transcribed verbatim and coded by three team members of the research team in several steps. We used the consolidated criteria for reporting qualitative research (COREQ) checklist to report our findings.

RESULTS

We interviewed 18 self-employed workers: 83% male, 49 years (SD 7), self-employed for 18 years (SD 9) and the majority (n = 14) worked in the construction sector. Thematic analysis revealed facilitators and barriers for work participation across three main themes: personal factors, work factors, and healthcare. Personal factors compassed sub-themes such as health and financial consequences. Work factors included sub-themes related to work demands and adaptations and healthcare encompassed sub-themes associated with work-related care and medication.

CONCLUSION

To our knowledge, this is the first qualitative study that investigated the perspectives of self-employed workers in physically demanding jobs regarding work participation. While most facilitators and barriers were consistent with those described in the literature for employees, certain factors, such as financial consequences of ceasing work, emerged important factors for work participation among self-employed workers.

The Functional Consequences of Long COVID Need to Be Addressed by Occupational Therapists

Long COVID-persistent health complications after recovery from coronavirus disease 2019 infection-is associated with activity limitations in nearly 48 million U.S. adults, affecting work, leisure, family, and community functioning. Occupational therapists are experts in customizing interventions to maximize performance of daily routines, and often treat individuals who experience similar functional impacts to those observed in long COVID. The large number of people experiencing new disability, as well as a lack of medical treatment options, make occupational therapy a crucial component of long-COVID research and multidisciplinary management. In this column, we discuss actionable steps occupational therapists can take to place them at the forefront of maximizing functional and quality-of-life outcomes for people with long COVID.

Ageism Healthcare: Implications for the Psychological Well-Being of Atlantic Canadian Healthcare Professionals

Ageism in healthcare is related to poor outcomes for older patients. The objective of this study was to evaluate the relationships between ageism and various aspects of the psychological well-being of healthcare professionals in Atlantic Canada. In 2023, an online survey of 294 healthcare professionals from various disciplines was conducted. This survey included items to measure expectations of aging, stress, burnout, emotional dissonance, and well-being. Results indicated that aging expectations were significantly related to burnout, perceived stress, well-being, and emotional dissonance. With the use of a path analysis, emotional dissonance partially mediated relationships between burnout and well-being with stress. However, aging expectations did not significantly predict emotional dissonance. Differences were found across professional groups on ageism. Conclusions support the need for increased awareness to the relationship between ageist attitudes and professionals' well-being, as well as the need for education and interventions to reduce false expectations about the aging process.

The contribution of a complex systems-based approach to progressive social resilience

The use of resilience in social practice has evolved from a theoretical framework at the intersection between individuals and their social ecology. Critics argue this theory still results in policies and practices that are too individualised, with the potential for negative social consequences. This paper further critiques contemporary understanding of resilience theory and its application. It juxtaposes complex systems theory with a social inequalities oriented resilience practice. This provides a paradoxical approach. It is acknowledged that state and public policy decisions and actions can be anti-resilient, undermining community and social resilience that already exists in the form of social relationships, self-organisation and co-production. Nevertheless, collective social resilience also illustrates the potential of local and service user organisations to contribute to an overall transformational change process.

Clinical applicability of signal heterogeneity and tumor border assessment on T2-weighted MR images to distinguish astrocytic from oligodendroglial origin of gliomas

BACKGROUND AND PURPOSE

Radiological features on magnetic resonance imaging (MRI) were attributed to oligodendroglioma, although the diagnostic accuracy in a real-world clinical setting remains partially elusive. This study investigated the accuracy and robustness of tumor heterogeneity and tumor border delineation on T2-weighted MRI to distinguish oligodendroglioma from astrocytoma.

MATERIALS AND METHODS

Eight readers from three different specialties (radiology, neurology, neurosurgery) with varying levels of experience blindly rated 79 T2-weighted MR images of patients with either oligodendroglioma or astrocytoma. After the first reading session, all readers were re-invited for a second reading session within three weeks. Diagnostic accuracy, including area under the receiver operator characteristics curve (AUC), and intra-observer variability and inter-observer variability were used as outcome measures.

RESULTS

Pooled sensitivity and specificity to distinguish oligodendroglioma from astrocytoma for the use of tumor heterogeneity were 59.9 % respectively 74.5 %, and 85.7 % respectively 40.1 % for tumor border. A second reading session did not result in a significant change in sensitivity or specificity for tumor heterogeneity (P = 0.752 and P = 0.733, respectively) or tumor border (P = 0.309 and P = 0.271, respectively). An AUC of 0.825 was achieved with regard to predicting oligodendroglial origin of gliomas. Intra-observer agreement ranged from moderate to very good for tumor heterogeneity (kappa-value 0.43-0.87) and tumor border (0.40-0.84). A moderate inter-oberserver agreement was achieved for tumor heterogeneity and tumor border (kappa-value of 0.50 and 0.45, respectively).

CONCLUSION

This study demonstrates that tumor heterogeneity and tumor borders on T2-weighted MRI could be used with moderate Finter-observer agreement to non-invasively distinguish oligodendroglioma from astrocytoma.

Menopause and the workplace: consensus recommendations from The Menopause Society

ABSTRACT

Menopause is a natural life transition experienced by half the world's population. Women aged 50 years and older are the fastest growing demographic group in many countries, making essential contributions to the workforce. Although menopause is a universal and natural life transition, the symptom experience is highly variable among women. Some women may experience few or no symptoms, whereas others may be bothered by moderate to severe symptoms for a decade or longer, which can adversely affect quality of life, relationships, job satisfaction, and career advancement. Indeed, menopause symptoms, including vasomotor and genitourinary symptoms, as well as sleep and mood disturbances are associated with multiple adverse work outcomes. Studies to date have demonstrated that these adverse work outcomes related to menopause symptoms include a compromised ability to work, reduced work productivity, absenteeism, and even loss of employment or an early exit from the workforce. Further, the relationship between menopause symptoms and work may be bidirectional, with certain aspects of the work environment being linked with a greater menopause symptom burden, such as insufficient restroom facilities, unpredictable or long work hours, the inability to take breaks, and confined or crowded workspaces. Thus, workplace solutions may need to be tailored based on women's individual needs, the work environment, and the type of work.The Menopause Society, in conjunction with an expert panel of medical and legal experts and women's health advocates, has developed a set of consensus recommendations that challenges employers to create a menopause-supportive workplace for their employees. These recommendations include, among other things, suggestions for employers to review policies and healthcare plans and benefits and to consider flexibility and accommodations that may be needed for some women with menopause symptoms. Guidance for women with menopause symptoms that affect them at work in terms of understanding their resources and empowering them to be self-advocates are also provided, as well as recommendations for what occupational health professionals should know and do for women with bothersome menopause symptoms in the workplace.

How clinical resource nurses can support new nurses and address safety concerns

ABSTRACT

Inexperienced nursing staff can jeopardize patient safety and contribute to burnout. This quality improvement project evaluated a clinical resource nurse (CRN) role designed to address disparities in nurses' skills and experience. Survey results suggested that the CRN role effectively supported novice nurses.

Exploring Canadian Career Firefighters' Understanding of the Return-to-Work Process After Musculoskeletal Injuries

PURPOSE

Firefighters perform dangerous and physically demanding work, increasing their risk of musculoskeletal injuries that can lead to work absences. Return-to-work procedures can help firefighters return-to-work sooner and safely. The purpose of this study was to explore what firefighters understand about return-to-work procedures in their workplaces, and what firefighters believe the facilitators and barriers to return-to-work are.

METHODS

Thirty-eight Canadian career firefighters were recruited for semi-structured interviews. Qualitative descriptive methods were used to analyze the transcripts. Two researchers performed the inductive coding and thematic analysis.

RESULTS

Five themes were identified: 1. Variation in the return-to-work process knowledge among firefighters based on their experiences; 2. Accessible medical resources and treatments to support injury recovery; 3. Light duties must be meaningful and suitable; 4. Pressures to return-to-work too soon may lead to negative consequences; and 5. Heavy physical demands of firefighting may become a barrier for return-to-work. 'Factors affecting RTW depended on personal experiences and context' was the overarching theme identified, as many reported facilitators for return-to-work were also reported as barriers in different contexts. There was a variation in the experiences and understanding of return-to-work.

CONCLUSION

There is a lack of knowledge of the return-to-work processes. Firefighters require access to clear return-to-work policies and procedures and treatments that are targeted to firefighting duties to support recovery from injuries and regain physical abilities after an injury. Firefighters must be able to perform all essential duties before returning to firefighting work, as returning to work too soon can lead to further injury.

Menstrual Cycle and Situational Match Variables: Effects on Well-Being in Professional Female Soccer Players

Purpose: We examined whether the situational match factors (location, result, and opposition quality), as well as playing position and menstrual cycle phase, influenced self-reported well-being in female soccer players. Methods: Twenty-two professional players (25 ± 5 years) from a squad in the Women's Super League in England self-reported their menstrual cycle phase via an online survey, and their soreness, sleep, stress, mood, and fatigue on a 1 (positive) to 5 (negative) scale on the morning of match day (MD) and for the next 3 days (referred to as MD + 1, MD + 2, MD + 3, respectively). Data was collected for 26 matches across the 2021-2022 season. Session rate of perceived exertion (sRPE) and total distance covered (measured with GPS) were measured on match and training days. Results: Menstrual cycle phase and the situational match factors had no influence on distance covered during matches and sRPE (p > .05). Sleep was worse on MD + 1 (p < .001; g = 1.59) and MD + 2 (p = .005; g = 0.98) after away matches. Stress and mood were > 28% worse after playing top vs. mid and bottom table opposition at MD + 1, and significantly worse when losing compared to winning and drawing (p > .05). Playing position and menstrual cycle phase has no influence on self-reported well-being (p > .05). Conclusion: Sleep quality was worse after away matches and losing matches negatively affects stress and mood for 2 days post-match, but menstrual cycle phase does not influence post-match well-being.

Association of Medical School Gap Year Research and Degree Programs With Otolaryngology Interview and Match Outcomes

OBJECTIVE

To investigate whether a gap year for either research or a master's degree is associated with interview offers or match outcomes among otolaryngology applicants.

METHODS

Using the Texas Seeking Transparency in Application to Residency (Texas STAR) database, we conducted a cross-sectional analysis of otolaryngology applicants from 2018 to 2022. Applicants were stratified based on the presence and type of gap year during medical school. Applicant characteristics, signaling, research productivity, and application costs were analyzed, with primary outcomes including number of interview offers and match status.

RESULTS

Among 564 otolaryngology applicant respondents to the Texas STAR survey, 160 (28%) reported a gap year, including 64 (40%) applicants participating in a research year, 65 (41%) completing a Master of Public Health or Science (MPH and MSc), and 31 (19%) completing a Master of Business Administration, Education, or other degree (MBA and MEd). Gap-year applicants who completed a research year or MPH/MSc degree received more interview offers (P < .01) than MBA, MEd applicants, or those without a gap year. Applicants with a research year had the most publications, oral presentations, abstracts, posters, and research experiences (all P < .01). When controlling for USMLE scores, clerkship honors, and applications submitted, applicants completing a research year or an MPH/MSc-degree received increased interview offers (P < .01). No significant differences were seen in expenditures or match rates.

CONCLUSIONS

Research and MPH/MSc gap years were associated with increased residency interview offers but not increased match success. Further longitudinal studies are needed to assess how yearlong experiences affect long-term career outcomes.

Driver drowsiness is associated with altered facial thermal patterns: Machine learning insights from a thermal imaging approach

Driver drowsiness is a significant factor in road accidents. Thermal imaging has emerged as an effective tool for detecting drowsiness by enabling the analysis of facial thermal patterns. However, it is not clear which facial areas are most affected and correlate most strongly with drowsiness. This study examines the variations and importance of various facial areas and proposes an approach for detecting driver drowsiness. Twenty participants underwent tests in a driving simulator, and temperature changes in various facial regions were measured. The random forest method was employed to evaluate the importance of each facial region. The results revealed that temperature changes in the nasal area exhibited the highest value, while the eyes had the most correlated changes with drowsiness. Furthermore, drowsiness was classified with an accuracy of 88 % utilizing thermal variations in the facial region identified as the most important regions by the random forest feature importance model. These findings provide a comprehensive overview of facial thermal imaging for detecting driver drowsiness and introduce eye temperature as a novel and effective measure for investigating cognitive activities.

Prevalence of burnout among physiotherapists: a systematic review and meta-analysis

BACKGROUND

Work-related burnout is a significant concern amongst healthcare professionals, including physiotherapists. It can negatively impact on both staff well-being and the quality of care delivered to patients.

OBJECTIVES

To estimate the prevalence of burnout among physiotherapists.

DATA SOURCES

PubMed, CINAHL, Web of Science, Embase, Scopus and PsycINFO, from inception to February 1st, 2022.

STUDY SELECTION OR ELIGIBILITY CRITERIA

Studies reporting burnout prevalence among physiotherapists.

DATA EXTRACTION AND DATA SYNTHESIS

Prevalence of burnout. Sub-analyses were performed grouping studies based on countries where surveys were conducted, classified as developed or developing countries. The risk of bias was assessed using a modified version of the Newcastle-Ottawa Scale.

RESULTS

32 studies were included in the systematic review and 31 in the meta-analysis, enrolling a total of 5984 physiotherapists from 17 countries. Pooled prevalence (95% confidence interval) of burnout was 8% (4-15). Prevalence figures for Maslach Burnout Inventory dimensions were: (i) emotional exhaustion, 27% (21-34) (ii) depersonalization, 23% (15-32) (iii) low personal accomplishment, 25% (15-40). Both overall and single components prevalence was higher, although not significantly, in studies from developing than in developed countries.

LIMITATIONS

Tools used to assess burnout and cut-off scores chosen to identify the burnout prevalence differed across studies.

CONCLUSION AND IMPLICATIONS OF KEY FINDINGS

Prevalence of burnout reported by physiotherapists appears high worldwide, in particular in developing countries, and compares with that reported by nurses and physicians. Substantial heterogeneity in the prevalence of burnout, in its definition and assessment methods across studies, and limited quality of most studies precludes drawing definitive conclusions.

Identification of key factors influencing unsafe behavior of decoration workers

This study explores the factors influencing unsafe behaviors among decorators. The study begins with a literature review on unsafe behaviors among construction workers, compiling a checklist of factors specific to decorators. Utilizing exploratory factor analysis (EFA), a measurement scale for these factors is developed. Subsequently, stepwise regression analysis (SRA) is conducted to validate relationships and identify crucial factors. Results categorize influencing factors into three dimensions: personal, organizational and environmental. Non-compliance with safety procedures and protocols is found to correlate directly with increased unsafe behavior at an individual level. Additionally, internal safety regulations within companies are identified as having a direct negative impact on unsafe behaviors at the organizational level. This study enhances our understanding of unsafe behaviors among decorators and offers recommendations for mitigation.

Evaluating the effectiveness of strategies for mitigating fatigue among construction workers in Abuja, Nigeria: a quantitative analysis

Fatigue is one of the menaces that contribute to the rising number of construction-related accidents and fatalities in projects. Therefore, the purpose of this study is to identify several strategies that can be adopted to mitigate fatigue in construction projects. This was achieved through a quantitative study. A questionnaire was the main instrument for data collection in the quantitative study. The study revealed that frustration/depression or work pressure is one of the significant causes of fatigue in construction projects. Fatigue risk management education and bonding among workers are some of the underlying strategies that can be used to mitigate the identified causes. Depending on the nature of the fatigue causative elements, the study further established that some mitigation strategies are more effective than others. Therefore, further studies should be conducted by prospective researchers on a range of attributes that may influence the success of fatigue mitigation strategies in construction projects.

Suicide and suicidality in Australian Defence Force veterans: A systematic scoping review

OBJECTIVE

Increased suicidality and suicide deaths among veterans of the Australian Defence Force have gained recent prominence. A systematic scoping review was conducted to identify, summarise and synthesise the existing literature relating to Australian veteran suicide and suicidality, with the objective of identifying future research priorities.

METHODS

We conducted a PRISMA-compliant systematic search on PubMed/MEDLINE, Embase and CINAHL databases for all manuscripts reporting primary data on suicide and suicidality in Australian veterans. The search was supplemented by grey literature and a search of reference lists. Manuscripts of any study type, published in the English language since the Vietnam era, were eligible for inclusion.

RESULTS

A total of 26 articles and reports, utilising a variety of mostly quantitative approaches, were included in the review. Findings, especially in larger and more recent studies, indicate increased suicidality in the veteran population. Suicide deaths appeared to increase with transition out of the military. Mental illness was identified as an important risk factor for suicide and suicidality. Current service was identified as a protective factor against suicide. There was mixed evidence regarding the impact of operational deployment on suicide and suicidality.

CONCLUSIONS

Gaps were identified in relation to the relative contributions to risk from transition, the various psychosocial correlates (for example, relationships, finances, employment), pre-service factors and the extent to which these are causal or mediating in nature. A better understanding of health service utilisation would also aid in targeting preventive efforts. Future research in these areas is warranted.

Comparison of multi-task ergonomic assessment methods for risk of upper extremity and low back musculoskeletal disorders

Work-related musculoskeletal disorder of upper extremity multi-task assessment methods (Revised Strain Index [RSI], Distal Upper Extremity Tool [DUET]) and manual handling multi-task assessment methods (Revised NIOSH Lifting Equation [RNLE], Lifting Fatigue Failure Tool [LiFFT]) were compared. RSI and DUET showed a strong correlation (rs = 0.933, p < 0.001) where increasing risk factor exposure resulted in increasing outputs for both methods. RSI and DUET demonstrated fair agreement (κ = 0.299) in how the two methods classified outputs into risk categories (high, moderate or low) when assessing the same tasks. The RNLE and LiFFT showed a strong correlation (rs = 0.903, p = 0.001) where increasing risk factor exposure resulted in increasing outputs, and moderate agreement (κ = 0.574) in classifying the outputs into risk categories (high, moderate or low) when assessing the same tasks. The multi-task assessment methods provide consistent output magnitude rankings in terms of increasing exposure, however some differences exist between how different methods classify the outputs into risk categories.

The impact of a specialist-led digital health application on menopause symptoms in the workplace: A single-arm, longitudinal evaluation

OBJECTIVES

The aim of the study was to evaluate the change in menopause symptoms and work impairment among a cohort of UK working women who utilised an employer-provided digital menopause health application offering education and personalised support.

STUDY DESIGN

We adopted a retrospective, single-arm, longitudinal approach by analysing data from 11,870 users of the Peppy Health menopause application. Users reported their menopause symptoms and work impairment on day 0 and after 90 and 180 days of application use.

MAIN OUTCOME MEASURES

Menopause symptoms were measured by the Menopause Rating Scale, while work impairment was measured by a single question.

RESULTS

A significant decrease in the severity of menopause symptoms was observed in users across menopause stages, except for premenopausal users who saw lower severity and no change over time. Improvement in menopause symptoms was positively associated with the degree of application engagement. Work impairment also significantly reduced over time for menopausal users, and a significant association was observed between a reduction in menopause symptoms and a decline in work impairment.

CONCLUSIONS

Our findings show that engaging with a digital menopause application is associated with an improvement in menopause symptoms, which lends initial support for the use of personalised digital solutions to help working women through the menopause transition.

Interrater Reliability and Precision of a Novel Hand Strength Assessment and Treatment Device: The GripAble

IMPORTANCE

Occupational therapy practitioners need modern tools for the assessment of maximal grip strength in clinical and remote settings.

OBJECTIVE

To establish the (1) interrater reliability and (2) precision of the GripAble among three raters with different expertise in occupational therapy when testing healthy participants, and to (3) evaluate the relative reliabilities of different approaches to estimating grip strength (i.e., one trial, mean of two trials, and the mean of three trials).

DESIGN

Measurement study.

SETTING

Minnesota Translational Musculoskeletal and Occupational Performance Research Lab, University of Minnesota, Minneapolis.

PARTICIPANTS

Thirty volunteers, age ≥18 yr, without any hand problems.

OUTCOMES AND MEASURES

Using GripAble, three occupational therapy raters with varied experience measured the maximal grip strength of the dominant and nondominant hands of all participants. Using the mean of three trials when testing grip strength with GripAble adds precision.

RESULTS

GripAble has excellent interrater reliability (i.e., intraclass correlation coefficient > .75) and acceptable precision (minimal detectable change < 15%) among healthy adults.

CONCLUSIONS AND RELEVANCE

GripAble allows occupational therapy practitioners with different experiences to assess grip strength in healthy hands quickly, precisely, and with excellent reliability. Additional research is needed on its psychometrics in clinical populations and capacities in remote monitoring and exergaming. Plain-Language Summary: The results of this study show that grip strength, an important biomarker and commonly assessed construct in occupational therapy, can be evaluated reliably, precisely, and rapidly with GripAble. The use of GripAble by occupational therapy practitioners in clinical settings may help to build an infrastructure for remote measurements and exergaming interventions in the future.

Pilot study of an online brief mindfulness-based intervention to improve the well-being of managers and reduce their stress at work

Objectives. The COVID-19 pandemic, remote work and new technologies have heightened workplace pressures. Effective response and essential organizational changes require business leaders to be more adaptable, with managers' presence playing a pivotal role in successful implementation. The study assesses a brief mindfulness-based emotional regulation for managers (MBERM) intervention, to reduce workplace stress and enhance managerial well-being. Methods. An 8-week non-randomized controlled trial was conducted with a waiting list control group and an intervention group. Pre-post differences were measured by Student's t test or Wilcoxon test, and effect size calculated using the Hedge's g formula. The sample included 23 managers (17 men and six women) with average age 50 years. The study assessed anxiety and depressive symptoms, psychological flexibility, perceived self-efficacy, general work-related well-being, perceived stress and mindfulness. Results. Statistically significant changes were observed in the intervention group in depression, anxiety, work-related acceptance and action, general self-efficacy, exhaustion, alienation, stress and non-reactivity. The control group showed no statistically significant changes in any of the variables. Conclusion. The MBERM intervention could improve the emotional and work-related well-being of managers and reduce stress levels and burnout. Further study of this intervention is needed to promote adherence and ensure a long-term improvement.

Preventive health measures in small and medium-sized enterprises: A scoping review on implementation strategies

OBJECTIVE

To describe implementation strategies for preventive health measures in SMEs and the effectiveness of the strategies on implementation outcomes.

METHODS

A literature search was performed in multiple electronic databases. Studies published between 2000 and 2021 that evaluated the implementation of preventive health measures in SMEs were included. Classification of implementation strategies was based on two complementary classification systems.

RESULTS

Nineteen studies, of which 5 RCTs were included. Eighteen distinct implementation strategies were reported. All studies applied a combination of implementation strategies, and nearly all reported a positive effect on one or more implementation outcomes: sustainability, acceptability, feasibility, penetration, fidelity, adoption, and appropriateness.

CONCLUSIONS

Overall, a positive effect of combined implementation strategies on the implementation outcome(s) was found. The 'distribution of educational materials' and 'provide ongoing consultation' combined show positive effects on sustainability.

Optimizing ergonomics during open, laparoscopic, and robotic-assisted surgery: A review of surgical ergonomics literature and development of educational illustrations

BACKGROUND

The surgical profession is plagued with a high prevalence of work-related musculoskeletal disorders. While numerous interventions have been tested over the years, surgical ergonomics education is still uncommon.

METHODS

The available literature on surgical ergonomics was reviewed, and with input from surgeons, recommendations from the review were used to create pictorial reminders for open, laparoscopic, and robot-assisted surgical modalities. These simple pictorial ergonomic recommendations were then assessed for practicality by residents and surgeons.

RESULTS

A review of the current literature on surgical ergonomics covered evidence-based ergonomic recommendations on equipment during open and laparoscopic surgery, as well as proper adjustment of the surgical robot for robot-assisted surgeries. Ergonomic operative postures for the three modalities were examined, illustrated, and assessed.

CONCLUSIONS

The resulting illustrations of ergonomic guidelines across surgical modalities may be employed in developing ergonomic education materials and improving the identification and mitigation of ergonomic risks in the operating room.

Traditional versus dynamic sitting: Lumbar spine kinematics and pain during computer work and activity guided tasks

Dynamic sitting may mitigate low back pain during prolonged seated work. The current study compared pelvis and lumbar spine kinematics, pain, and work productivity, in traditional and dynamic sitting. Sixteen participants completed three 20-min blocks of computer work and activity guided tasks in a traditional office chair or backless and multiaxial rotating seat pan while kinematics were measured from accelerometers on the low back. Pain ratings were recorded on a visual analogue scale every 10 min. Similar pelvis and lumbar kinematics emerged when performing computer work in traditional and dynamic sitting. Pelvis and lumbar sagittal and frontal plane shifts and fidgets were largest for dynamic sitting in the activity guided tasks. Buttocks pain was higher in dynamic sitting, but low back pain and work productivity were unaffected. Dynamic sitting increased spine movement during activity guided tasks, without negatively impacting lumbar kinematics, low back pain, or productivity during seated computer work.

Ageism and (Successful) Digital Engagement: A Proposed Theoretical Model

Recently, scholars have highlighted the detrimental consequences of technology-based ageism. Digital technology (DT) is commonly discoursed as an opportunity to promote Successful Aging. Nevertheless, the theoretical implications of ageism, DT, and Successful Aging are underexplored. This paper presents a new theoretical model of Digital Engagement and Ageism (D-EngAge), which elaborates on the potential impacts of ageism on digital engagement and participation in later life and explains how ageism may pose a threat to realizing the potential of DT to promote Successful Aging. The D-EngAge model was developed based on a synthesis of findings from 12 recent studies we conducted on the intersection of ageism and DT. Findings were synthesized through Iversen's clasification of four dimensions of ageism, demonstrating how ageism as a multifaceted construct has a reciprocal relationship with digital engagement on the micro- (individual), meso- (social interaction), and macro-levels (discourses and societal practices). Consequently, digital engagement on these levels may exacerbate or reduce technology-based ageism. This forum paper identifies ageism as a barrier to utilizing DT, critically discusses power imbalances, and deconstructs Successful Aging discourses regarding digital engagement. Theoretical implications and recommendations for future interventions and policy measures to mitigate ageism and promote digital engagement and participation in later life are presented.

Experiences of Working with Lower Limb Osteoarthritis: A Qualitative Study

PURPOSE

Pain and disability associated with lower limb osteoarthritis (OA) may contribute to difficulties at work. This study aimed to understand the perspectives of workers with lower limb OA on difficulties, concerns, and coping strategies used at work.

METHODS

Twenty-two individuals with lower limb OA who were working in paid employment participated in semi-structured interviews. Data were qualitatively analyzed using an inductive thematic approach. Codes were identified and refined through review of interview transcripts and discussion with the research team.

RESULTS

Six themes were identified in relation to experiences working with lower limb OA. Themes were as follows: weight-bearing physical demands are challenging; lower limb OA can affect work performance; emotional consequences of pain; concerns about work in the future; positive experiences of supportive colleagues and managers; and minimal effects on sedentary work. Three themes were identified relating to strategies to manage at work: adjustments at work help manage pain and avoid exacerbations; regular strategies to manage pain; and healthcare professionals are consulted, but usually not specifically for work.

CONCLUSIONS

Workers with lower limb OA experience physical and emotional difficulties at work that can impact work performance. Workers are concerned about longevity and job security and use a range of strategies to manage symptoms and remain at work. Employers, employees, and healthcare professionals may need to work together to create workplace accommodations to help workers with lower limb OA confidently remain in work.

Preventing Surgeon Work-Related Musculoskeletal Disorders: A Pilot Study of the Comprehensive Operating Room Ergonomics (CORE) Program

IMPORTANCE

Work-related musculoskeletal disorders (WMSDs) among surgeons are markedly increasing. Several proposed interventions to reduce WMSDs among surgeons have been studied, but few follow an occupational therapy-oriented approach addressing biomechanical, psychophysical, and psychosocial risk factors.

OBJECTIVE

To design, implement, and assess the potential of the Comprehensive Operating Room Ergonomics (CORE) program for surgeons, a holistic evidence-based ergonomics and wellness intervention grounded in occupational therapy principles.

DESIGN

Mixed-methods pilot study with the quantitative strand embedded in the qualitative strand.

SETTING

University-affiliated hospital.

PARTICIPANTS

Six laparoscopic surgeons.

OUTCOMES AND MEASURES

CORE program outcomes were assessed using qualitative and quantitative data to indicate changes in posture, physical discomfort, sense of wellness, and operating room (OR) ergonomic performance. The Rapid Upper Limb Assessment (RULA) was used to quantify surgeons' WMSD risk level before and after intervention.

RESULTS

There were 12 baseline observations (two for each participant), and two or three post-CORE implementation observations. A statistically significant difference, F(1, 6) = 8.57, p = .03, was found between pre- and post-occupational therapy intervention RULA scores. Thematic analysis of surgeon feedback, which was overwhelmingly positive, identified five themes: postural alignment, areas of commonly reported physical pain or discomfort, setup of the OR environment, surgical ergonomics training, and ergonomics in everyday life.

CONCLUSIONS AND RELEVANCE

The CORE program effectively decreased ergonomic risk factors to optimize surgeons' occupational performance in the OR. This study demonstrates a potential solution to how occupational therapists can holistically support surgeons and health care providers who are at risk for WMSDs. Plain-Language Summary: By 2025, a surgeon shortage is expected, partly because of the increase in surgeons' work-related musculoskeletal disorders, which affect their health and job continuity. This pilot study shows that the Comprehensive Operating Room Ergonomics program effectively addresses these problems. The study also serves as a framework for occupational therapy professionals to work with health care providers on ergonomics, benefiting population health. Results suggest that this approach could enhance surgeons' work conditions, supporting the American Occupational Therapy Association's Vision 2025 to improve health and quality of life.

Effects of computer use on upper limb musculoskeletal disorders and function in academicians

Objectives. This study aimed to investigate the effects of academician's demographic characteristics and computer usage habits on upper limb musculoskeletal disorders (MSDs) and function. Methods. A cross-sectional observational study was conducted with 100 academicians. Data were collected using questionnaires, which included the patient-rated wrist evaluation questionnaire - Turkish version (PRWE-T), the Cornell musculoskeletal discomfort questionnaire - Turkish version (CMDQ-T), the upper extremity functional index - Turkish version (UEFI-T), demographic characteristics and average daily computer usage time. Results. A low-level significant correlation was found between the age of the individuals and the CMDQ-T forearm (p = 0.044; r = 0.202) and CMDQ-T wrist (p = 0.001; r = 0.337) scores. Women had higher CMDQ-T neck scores and lower UEFI-T scores than men (p < 0.05). Academicians who used computers for 6 h a day or more had higher PRWE-T and CMDQ-T neck, shoulder, upper arm and forearm scores, and had a lower UEFI-T score (p < 0.05). Conclusion. Neck, shoulder, upper arm and forearm symptoms were higher and upper extremity function was impaired in academicians who used computers for 6 h a day or more. Besides, gender and age were associated with upper limb MSDs and function, but occupation duration did not affect those outcomes in academicians.

Save Your Back: Comparison of the Compressive Force on the Lower Back Based on Differences in the Training Techniques

INTRODUCTION

Musculoskeletal injury prevention for nurses is aimed at removing the need to manually position patients. In the ED, this is not always possible or practical. The purpose of this study is to compare the calculated estimated compressive force on the lumbar spine between recommended lifting techniques and the SHAPE lifting method during the horizontal transfer of a patient.

METHODS

Twenty-one student nurses completed the horizontal transfer of a simulated patient while motion was collected using inertial measurement units. Motion data were analyzed to calculate an estimated compressive force on the lumbar spine while completing the movement based on current recommended lifting methods and while using the SHAPE lifting method.

RESULTS

A significant reduction in estimated peak and average compressive force at the lumbar spine was found during both the push and the pull portions (P < .001) of the horizontal transfer.

DISCUSSION

While the optimal way to limit musculoskeletal injury among nurses is to eliminate the need for manual handling of a patient, this is not always possible in the ED. It is critical that when emergency nurses must reposition a patient, they perform the movement in the most biomechanically sound method while using a friction reduction. These findings, coupled with the previous biomechanical risk factor reduction related to the SHAPE lifting intervention, gives promise to a safer lifting strategy for emergency nurses moving forward.

Muscular endurance and its association with neck pain, disability, neck awareness, and kinesiophobia in patients with chronic neck pain

BACKGROUND

Recent studies revealed the connection between the endurance of neck muscles and pain, neck awareness, and fear of movement in patients with chronic neck pain in literature.

OBJECTIVES

To investigate the association between cervical, scapular, trunk, and upper extremity muscles' endurance and neck pain, disability, neck awareness, and kinesiophobia in patients with chronic neck pain.

DESIGN

Cross-sectional, observational study.

METHODS

Thirty-six patients with chronic neck pain (aged 18-65 years) were included in the study. Endurance tests were performed for 9 muscles/muscle groups in the cervical and scapular region, upper limb, and trunk. Pain severity, neck disability, neck awareness, and fear of movement were measured by Visual Analog Scale (VAS), Neck Disability Index (NDI), Fremantle Neck Awareness Questionnaire (FreNAQ), and Tampa Scale of Kinesiophobia (TSK), respectively.

RESULTS

Negative, weak-to-moderate relations were found between VAS (at rest and during activity) and the endurance of muscles evaluated in the cervical and scapular regions, upper extremity, and trunk as well as between NDI and endurance of the same muscles, similar to the relations between FreNAQ scores and the endurance of the cervical flexor, anterior trunk flexor, and upper extremity muscles (p < 0.05). No relation was found between the endurance of the muscles and TSK (p > 0.05).

CONCLUSIONS

Since the decrease in upper extremity, scapular region, and trunk muscles' endurance may contribute to neck pain and disability, and decrease neck awareness in patients with chronic neck pain; the evaluation of muscular endurance of upper body and trunk should also be considered.

Molecular Point-of-Care Testing in the Emergency Department for Group A Streptococcus Pharyngitis : A Randomized Trial

OBJECTIVES

To compare clinical and health systems outcomes of rapid molecular testing versus throat culture recovery for the management of group A Streptococcus (GAS) pharyngitis in a pediatric emergency department (PED).

METHODS

We conducted a single-center randomized trial of children (3-17 years) presenting to a PED with suspected GAS pharyngitis. A single dual-headed throat swab was collected, and participants were randomized to 1 of 2 parallel treatment groups with 1:1 allocation: point-of-care (POC) nucleic acid amplification testing or standard throat culture. The primary outcomes were time to throat pain +/- fever resolution. Secondary outcomes included absenteeism, length of stay, return visits to care, and antibiotic prescriptions and utilization.

RESULTS

A total of 227 children were randomly assigned to culture (n = 115) or POC (n = 112) testing. Antibiotics were initiated earlier in the POC group by approximately 1 day (95% confidence interval, -0.40 to -1.58). No associated difference in time to throat pain or fever resolution was observed between groups. There was a decrease in the proportion of prescribed antibiotics in the POC group (0.35) compared with the culture group (0.79; P < 0.001). Otherwise, no significant differences in secondary outcomes were observed.

CONCLUSIONS

Establishing a POC nucleic acid amplification testing program for GAS in a PED facilitates earlier treatment and fewer antibiotic prescriptions. Although this did not translate to improved clinical and health systems outcomes in our study, it may serve as an important tool amid evolving pediatric febrile illnesses and growing antimicrobial resistance patterns.
