Workplace Reintegration Programs, Policies, and Procedures for Nurses Experiencing Operational Stress Injury: A Scoping Literature Review.

BACKGROUND: Nurses experience elevated rates of operational stress injuries (OSIs). This can necessitate taking leave from work and subsequently engaging in a workplace reintegration process. An unsuccessful process can have long term impacts on a nurse's career, affecting the individual, their family, and broader community, while contributing to nursing shortages. A knowledge gap regarding the workplace reintegration of nurses experiencing mental health challenges, impedes the development and implementation of initiatives that might increase the success of nurses reintegrating into the workplace. This scoping review explored the existing literature concerning workplace reintegration for nurses experiencing OSIs. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) reporting guidelines were utilized. Three key search terms across six databases were employed followed by a qualitative content analysis of the resulting literature. RESULTS: Eight documents were included. The literature exhibited high heterogeneity in objectives, content, and article types. The content analysis revealed five themes: (1) recognizing stigma, (2) elements of successful workplace reintegration, (3) considerations for military nurses, (4) considerations for nurses with substance use disorders, and (5) gaps in the existing literature. CONCLUSION: A paucity of programs, policies, procedures, and research exists regarding workplace reintegration for nurses facing mental health challenges. It is imperative to recognize that nurses may experience OSIs, necessitating mental health support, time off work, and operationally/culturally-specific assistance in returning to work. Innovative and evidence-based approaches to workplace reintegration are needed to enhance the retention of a skilled, experienced, compassionate, and healthy nursing workforce.

The effect of muscle ultrastructure on the force, displacement and work capacity of skeletal muscle.

Skeletal muscle powers animal movement through interactions between the contractile proteins, actin and myosin. Structural variation contributes greatly to the variation in mechanical performance observed across muscles. In vertebrates, gross structural variation occurs in the form of changes in the muscle cross-sectional area : fibre length ratio. This results in a trade-off between force and displacement capacity, leaving work capacity unaltered. Consequently, the maximum work per unit volume-the work density-is considered constant. Invertebrate muscle also varies in muscle ultrastructure, i.e. actin and myosin filament lengths. Increasing actin and myosin filament lengths increases force capacity, but the effect on muscle fibre displacement, and thus work, capacity is unclear. We use a sliding-filament muscle model to predict the effect of actin and myosin filament lengths on these mechanical parameters for both idealized sarcomeres with fixed actin : myosin length ratios, and for real sarcomeres with known filament lengths. Increasing actin and myosin filament lengths increases stress without reducing strain capacity. A muscle with longer actin and myosin filaments can generate larger force over the same displacement and has a higher work density, so seemingly bypassing an established trade-off. However, real sarcomeres deviate from the idealized length ratio suggesting unidentified constraints or selective pressures.

Determinants of burnout in Canadian health care workers during the COVID-19 pandemic.

Background: Health care workers (HCWs) are among the most vulnerable groups to experience burnout during the coronavirus (COVID-19) pandemic. Understanding the risk and protective factors of burnout is crucial in guiding the development of interventions; however, the understanding of burnout determinants in the Canadian HCW population remains limited.Objective: Identify risk and protective factors associated with burnout in Canadian HCWs during the COVID-19 pandemic and evaluate organizational factors as moderators in the relationship between COVID-19 contact and burnout.Methods: Data were drawn from an online longitudinal survey of Canadian HCWs collected between 26 June 2020 and 31 December 2020. Participants completed questions pertaining to their well-being, burnout, workplace support and concerns relating to the COVID-19 pandemic. Baseline data from 1029 HCWs were included in the analysis. Independent samples t-tests and multiple linear regression were used to evaluate factors associated with burnout scores.Results: HCWs in contact with COVID-19 patients showed significantly higher likelihood of probable burnout than HCWs not directly providing care to COVID-19 patients. Fewer years of work experience was associated with a higher likelihood of probable burnout, whereas stronger workplace support, organizational leadership, supervisory leadership, and a favourable ethical climate were associated with a decreased likelihood of probable burnout. Workplace support, organizational leadership, supervisory leadership, and ethical climate did not moderate the associations between contact with COVID-19 patients and burnout.Conclusions: Our findings suggest that HCWs who worked directly with COVID-19 patients, had fewer years of work experience, and perceived poor workplace support, organizational leadership, supervisory leadership and ethical climate were at higher risk of burnout. Ensuring reasonable work hours, adequate support from management, and fostering an ethical work environment are potential organizational-level strategies to maintain HCWs' well-being.

Canadian HCWs endorsed high levels of burnout during the COVID-19 pandemic.Having direct contact with COVID-19 patients and having fewer years of work experience were associated with a higher likelihood of probable burnout.Having stronger workplace support, greater perceived organizational and supervisory leadership, and a favourable ethical climate were associated with a lower likelihood of probable burnout.

Comprehensive Assessment of Cardiac Function in Breast Cancer Patients: Integrating Multiparametric Speckle Tracking Imaging and Conventional Echocardiography Parameters.

Purpose The purpose of this study is to comprehensively evaluate the role of different echocardiography parameters in breast cancer patients undergoing chemotherapy. While echocardiography examination with calculation of ejection fraction (EF), is pivotal for patient monitoring, its operator dependence and insensitivity to subtle changes in left ventricular (LV) contractility present challenges. Global longitudinal strain (GLS), derived from speckle tracking, is more sensitive and stable than EF. Our research aimed to delineate supplementary echocardiography measurements beneficial for the cardiological monitoring of breast cancer patients. Methods Patients were followed up with echocardiography at baseline, during, and after the chemotherapy. Conventional echocardiography and multiple speckle tracking imaging parameters including myocardial work index, atrial strain, twist, and automatic EF were investigated. Results A total of 25 patients were recruited. A subset (15/25) exhibited pronounced GLS reduction, associated with decreased EF and altered cardiac mechanics. Patients with unchanged GLS were often hypertensive and on specific medications, in particular angiotensin-converting enzyme inhibitors (ACE inhibitors)/angiotensin II receptor blockers (ARBs), potentially indicating protective effects. Despite stability in other parameters, GLS and EF sensitivity highlight their importance. A strong correlation between manual and automated EF measurement methods was also observed. Conclusion Despite the small sample size, across diverse echocardiography parameters, GLS and EF are primarily affected by chemotherapy. Hypertensive individuals exhibited lower susceptibility to chemotherapy-induced damage, likely attributed to the cardioprotective properties of ACE inhibitors and angiotensin II receptor blockers. A strong correlation between automatic and Simpson-based EF was found.

Impact of individual and work factors on the heat-related consequences among power plant workers in a hot region.

Prolonged exposure to hot environments increases the probability of heat load that may cause occupational heat strain to workers. This study investigates the impact of individual and work-related factors on the heat-related consequences among power plant workers in a hot region. This cross-sectional study was conducted in 2020. The collecting data tool was a validated self-reported 26 item questionnaire and completed in 534 individuals. We used logistic regression, Adjusted odds ratio (AOR) and maximum likelihood evaluations for data analysis. The findings indicated that age, work environment, physical work demands and drinking fluids during work hours are significant with heat exposure perception, heat-related symptoms, and work performance (P-value<0.05). Further, the male workers aged 40-49 are more prone to heat-related symptoms (AOR 1.34, 95% CI 1.18-2.13). The importance of addressing heat stress in occupational settings is necessary and informing strategies to help workers adapt to heat in hot workplaces.

"Exploring job demands and resources influencing mental health and work engagement among physical therapists: a cross-sectional survey of Norwegian physical therapists."

BACKGROUND: Physical therapists play a vital role in the Norwegian health care system, and their work environment may be a significant determinant for their wellbeing and job performance. OBJECTIVE: 1) Assess differences in work environment, mental health problems, and work engagement between physical therapists working in specialist versus municipal health care services. 2) Assess the relationships between work environment factors and work engagement and mental health problems. METHODS: In this cross-sectional study, 273 physical therapists responded to the Survey for Workplace Health Promotion (response rate = 35%). Independent-sample t-tests, Pearson correlations, and multiple regression analyses were performed. RESULTS: This study did not find any significant differences between physical therapists working in Norwegian hospitals and therapists working in the municipal health care services. Analyses showed that general demands (ß = 0.21), fragmented work tasks (0.18), predictability (-0.17) and social support (-0.34) were associated with mental health problems, while meaningful work (0.41), the opportunity to use one's strengths and potential (0.14), and social support (0.25) were associated with higher work engagement. CONCLUSION: This study highlights the role of poor job design and professional isolation as hindrances to work engagement among physical therapists, whereas work related meaningfulness and peer support promote their health and wellbeing.

Identifying factors associated with physical therapy use versus non-use among injured workers with back pain in Washington State.

BACKGROUND: There is little information about predictors of physical therapy (PT) use among injured workers with back pain. The primary objective of this study is to investigate the associations between PT use and baseline factors not routinely captured in workers' compensation (WC) data. METHODS: We conducted a secondary analysis using the Washington State Workers' Compensation Disability Risk Identification Study Cohort, which combines self-reported surveys with claims data from the Washington State Department of Labor and Industries State Fund. Workers with an accepted or provisional WC claim for back injury between June 2002 and April 2004 were eligible. Baseline factors for PT use were selected from six domains (socio-demographic, pain and function, psychosocial, clinical, health behaviors, and employment-related). The outcome was a binary measure for PT use within 1 year of injury. Bivariate and multivariable logistic regression models were conducted to evaluate the associations between PT use and baseline factors. RESULTS: Among the 1370 eligible study participants, we identified 673 (49%) who received at least one PT service. Baseline factors from five of the six domains (all but health behaviors) were associated with PT use, including gender, income, pain and function measures, injury severity rating, catastrophizing, recovery expectations, fear avoidance, mental health score, body mass index, first provider seen for injury, previous injury, and several work-related factors. CONCLUSION: We identify baseline factors that are associated with PT use, which may be useful in addressing disparities in access to care for injured workers with back pain in a WC system.

Effect of high-fat diet on isometric, concentric and eccentric contractile performance of skeletal muscle isolated from female CD-1 mice.

Despite evidence inferring muscle and contractile mode-specific effects of high-fat diet (HFD), no study has yet considered the impact of HFD directly on eccentric muscle function. The present work uniquely examined the effect of 20-week HFD on the isometric, concentric and eccentric muscle function of isolated mouse soleus (SOL) and extensor digitorum longus (EDL) muscles. CD-1 female mice were randomly split into a control (n = 16) or HFD (n = 17) group and for 20 weeks consumed standard lab chow or HFD. Following this period, SOL and EDL muscles were isolated and assessments of maximal isometric force and concentric work loop (WL) power were performed. Each muscle was then subjected to either multiple concentric or eccentric WL activations. Post-fatigue recovery, as an indicator of incurred damage, was measured via assessment of concentric WL power. In the EDL, absolute concentric power and concentric power normalised to muscle mass were reduced in the HFD group (P < 0.038). HFD resulted in faster concentric fatigue and reduced eccentric activity-induced muscle damage (P < 0.05). For the SOL, maximal isometric force was increased, and maximal eccentric power normalised to muscle mass and concentric fatigue were reduced in the HFD group (P < 0.05). HFD effects on eccentric muscle function are muscle-specific and have little relationship with changes in isometric or concentric function. HFD has the potential to negatively affect the intrinsic concentric and eccentric power-producing capacity of skeletal muscle, but a lack of a within-muscle uniform response indicates disparate mechanisms of action which require further investigation.

Altered coordination between sleep timing and cortisol profiles in night working female hospital employees.

BACKGROUND: Cortisol typically peaks in the morning after waking up and declines throughout the day, reaching its lowest levels during nighttime sleep. Shift work can cause misalignment between cortisol levels and sleep-wake timing. We analyzed this misalignment in female shift workers focusing on the timing and extent of these changes. METHODS: We conducted a cross-sectional study involving 68 shift workers (aged 37 ± 10 years) and 21 non-shift workers (aged 45 ± 10 years) from a hospital. Shift workers were monitored through two day shifts and three night shifts, whereas non-shift workers were monitored during two day shifts. Each participant collected six to eight saliva samples (depending on their shift type) and provided sleep timing information, which was recorded via polysomnography and sleep diaries. Generalized additive mixed models were used to estimate shift-specific differences in cortisol smooth curves. Summary measures calculated for the cortisol smooth curves included cortisol awakening response, peak-to-bed slope, and total output. RESULTS: Between shift workers and non-shift workers, we observed similar diurnal cortisol profiles with a steep negative diurnal slope during day shifts. In shift workers on night shifts, a flattened U-shaped cortisol profile after the post-awakening maximum was observed, with a peak-to-bed slope close to zero. When comparing night to day shifts in the group of shift workers, mean cortisol levels were lower between 42 and 56 minutes and 1.8-11.9 hours after waking up, and higher between 14.9 and 22 hours after waking up. CONCLUSION: Our findings indicate altered cortisol profiles in female hospital employees on night shifts. Specifically, cortisol levels were lower at night when higher levels would typically be necessary for work activities, and higher at bedtime after a night shift, when levels should normally be low.

Targeting subclinical ventricular dysfunction in atrial fibrillation: What can myocardial work add?

Atrial fibrillation (AF) could impact on left ventricular function leading to a sublinical myocardial dysfunction, as identified by myocardial work parameters in a population-based cohort of AF patients compared with healthy individuals; factors associated with these parameters are also shown. SBP: systolic blood pressure; LAVI: left atrial volume index.

Indium Tin Oxide Induced Internal Positive Feedback and Indium Ion Transport in Perovskite Solar Cells.

Stability is the most pressing challenge hindering the commercialization of perovskite solar cells (PSCs), and previous efforts focused more on enhancing the resistance of PSCs to external stimulus. Here, we found that the indium tin oxide (ITO) will deteriorate the photovoltaic performance of PSCs through positive feedback cycles. Specifically, the perovskite degradation products will cross the electron transport layer  to chemically etch the electrode ITO to generate In3+, which will migrate upwards into the perovskite film. Then, the reaction that corrodes ITO consumes the decomposition products of perovskite and shifts the balance of the perovskite decomposition reaction, further promoting the degradation and thus falling into a positive feedback cycle. Moreover, the In3+ in the perovskite film was found to accumulate at the upper surface, which would lead to n-type doping of perovskite film to form the energy barrier for interface carrier extraction. Subsequently, the chelating molecule ethylenediaminetetraacetic acid disodium salt (EDTA-2Na) was introduced onto ITO to firmly chelate the In3+ and prevent it from migrating upward, thus breaking this internal positive feedback cycle and significantly enhancing the efficiency and stability of PSCs. This work provides new perspectives for understanding the mechanism of photovoltaic performance loss and ionic transport in PSCs.

A comparative analysis of sleep quality and time management skills between shift and non-shift police officers.

PURPOSE: The sleep quality of police officers working in shifts is negatively affected due to long working hours and sleeping less during the day. In our study, we aimed to examine the differences in sleep quality and time management skills in police officers working with shift and non-shift system. METHODS: 106 police officers, 46 of whom worked in the shift system, 60 of whom worked in the non-shift system, and whose mean age was 27.6 ± 0.9 [min 20, max 40] were included in the study. Sleep quality was assessed with the Pittsburgh Sleep Quality Index[PSQI] and time management skills with the Time Management Questionnaire[TMQ]. RESULTS: While the TMQ total score was 80.91 ± 12.61 for police officers working in shifts, it was 72.41 ± 12.62 for police officers working non-shift. The PSQI total score was 5 in both groups. There was a difference between the TMQ time planning, TMQ time attitudes sub-dimensions, and TMQ total scores of police officers working in the shift system and those working in the non-shift system[p < 0.05]. While poor sleep quality was observed between both groups, there was no difference in sleep quality[p > 0.05]. CONCLUSION: There was no difference in sleep quality between police officers working in shifts and non-shifts. However, the time management skills of police officers working in shifts were better than those of police officers working in non-shifts. We believe that training programs to improve sleep health and time management skills in police officers are needed for both the sleep quality and well-being of police officers and public safety.

Organizational support enhances nurses' work-family enrichment: a person-context interactionist perspective.

Introduction: Attaining a favorable work-life balance is a complex and ongoing challenge in the nursing profession. According to a person-context interactionist perspective and the two-factor theory, this study investigated the underlying mechanism by which organizational support impacts work-family enrichment via protective factors (i.e., decent work) and depleting factors (i.e., burnout) among Chinese nurses. Methods: A descriptive cross-sectional research design was utilized in this study, employing an online questionnaire as the primary method for data collection. The study included 355 nurses who completed a self-reported questionnaire designed to measure variables such as organizational support, decent work, burnout, work-family enrichment, and demographic information. The collected data were analyzed using a chain mediation model in PROCESS macro (Model 6). Results: The findings of the analysis revealed that nurses reporting higher levels of organizational support also exhibited a greater sense of work-family enrichment. Moreover, the study identified indirect effects of organizational support on work-family enrichment, mediated by decent work and burnout. Discussion: These findings suggest that targeted interventions aimed at promoting organizational support can contribute to the overall well-being and work-life balance of nurses.

The Relationship Between Work-Related Stress and Depression: A Scoping Review.

Objectives: Work-related stress is highly prevalent. Recent systematic reviews concluded on a significant association between common work-related stress measures and depression. Our scoping review aims to explore whether work-related psychosocial stress is generally associated with depression or depressiveness, the extent and methodology of the primary research undertaken on this topic and to elucidate inconsistencies or gaps in knowledge. Methods: We searched for literature in Pubmed, PsycInfo and Web of Science including full reports in seven languages published between 1999 and 2022 and applied the PRISMA statement for scoping reviews criteria. Results: Of 463 primarily identified articles, 125 were retained after abstract and full-text screening. The majority report significant associations between work-related stress and depression. Cross-sectional studies are most prevalent. Sufficient evidence exists only for job strain and effort-reward imbalance. Most studies are from Asia, North America and Europe. The health sector is the most studied. Several research gaps such as the lack of interventional studies were identified. Conclusion: The consistency of most studies on the significant association between work-related stress and depression is remarkable. More studies are needed to improve evidence and to close research gaps.

Factors predicting the adhesion and prolonged lost days of work in patients with extensor tendon adhesion of the hand.

Objective: Extensor tendon adhesion receive less attention recently. This study aims to analyze influencing factors of adhesion and prolonged lost days of work in patients with extensor tendon adhesion of the hand. Method: We performed a retrospective study in patients with extensor tendon injuries who underwent primary surgical repair and early rehabilitation. We observed the differences between non-tendon adhesion and adhesion patients after surgical repair, and used the receiver operating characteristic curve to distinguish them. Then we explored the influencing factors of adhesion. In addition, we studied the lost days of work and the influencing factors. Results: A total of 305 patients were included. 24.6% patients appeared tendon adhesion and the mean lost days of work was 12 weeks. MHISS scores, VAS scores, occupation and blood triglyceride level were the influencing factors of adhesion. The adhesion patients have increased MHISS scores (p < 0.001), VAS scores (p < 0.001), blood triglyceride levels (p < 0.001) and lost days of work (p < 0.001) than non-tendon adhesion. The optimal cut-off value of blood triglyceride level to distinguish non-tendon adhesion from adhesion was 1.625 mml/L, and MHISS scores was 20.5. Smoking, MHISS scores, blood triglyceride levels were the influencing factors of lost days of work in adhesion patients. There was positive correlation between lost days of work and triglyceride level (r = 0.307, p = 0.007), and MHISS scores (r = 0.276, p = 0.016). Conclusion: To minimize the occurrence of adhesion, doctors should pay attention to patients with higher MHISS and VAS scores, blood triglyceride levels, especial for the blue-collar and unemployed one. High triglyceride level may be a new influencing factor.

Doctoral graduates' attitudes toward scholarly work and Institutional Review Board and Quality Improvement Committee education and submission processes: A pilot study.

BACKGROUND: Educators are challenged to find better ways to prepare doctoral nursing students to conduct scholarly work involving human subjects. PURPOSE: To better understand doctoral nursing students' attitudes toward programmatic scholarly work and Institutional Review Board (IRB)/Quality Improvement Committee (QIC) education and submission processes. METHODS: Recent Doctor of Nursing Practice (DNP) and Philosophy of Nursing (PhD) graduates were recruited using convenience sampling techniques to participate in this cross-sectional, descriptive, mixed-methods pilot study. Data were collected using two researcher-developed instruments. DISCUSSION: Nineteen doctoral nursing students participated in this study. Students most often used a quantitative approach with health care providers to complete their scholarly work requirements. Both PhD and DNP participants were overall satisfied with the IRB/QIC content in the curricula and the submission process. Four themes were identified: (a) Efficiency, (b) Collaboration, (c) Faculty Mentorship, and (d) Areas for Improvement. CONCLUSION: Findings from this pilot study may be used to enhance IRB/QIC processes through revision of administrative processes and student education.

Physical work environment in an activity-based flex office: a longitudinal case study.

OBJECTIVE: This study aimed to investigate and explore Occupational Health and Safety (OHS) management, office ergonomics, and musculoskeletal symptoms in a group of office workers relocating from cell offices to activity-based flex offices (AFOs). METHODS: The analysis was based on qualitative interview data with 77 employees and longitudinal questionnaire data from 152 employees. RESULTS: Results indicate that there was a need to clarify roles and processes related to the management of OHS. Self-rated sit comfort, working posture, and availability of daylight deteriorated and symptoms in neck and shoulders increased after the relocation and seemed to be influenced by many factors, such as difficulties adjusting the workstations, the availability of suitable workplaces, and age, sex, and individual needs. CONCLUSION: Research on the long-term effects of physical work environments and management of (OHS) issues after implementing activity-based flex offices is sparse. This study demonstrates the importance of planning and organising OHS issue management when implementing an AFO, and to carefully implement office ergonomics among office workers.

Diagnostic errors in rheumatology and medico-legal consequences.

Medical errors and adverse effects of treatment are inherent to medical practice. Like any other medical specialty, rheumatology is not exempt. Although the problem is imprecisely quantified, according to some authors it affects up to 10% of hospitalised patients. Describing and qualifying misdiagnoses in rheumatology will help us to understand and reduce these. Further, misdiagnosis generates unjustified costs and medico-legal consequences with errors in initial diagnosis the basis for medico-legal disputes involving assessment of work incapacity.

Energy-Level Interpretation of Carbazole Derivatives in Self-Assembling Monolayer.

Energy-level alignment is a crucial factor in the performance of thin-film devices, such as organic light-emitting diodes and photovoltaics. One way to adjust these energy levels is through chemical modification of the molecules involved. However, this approach may lead to unintended changes in the optical and/or electrical properties of the compound. An alternative method for energy-level adjustment at the interface is the use of self-assembling monolayers (SAMs). Initially, SAMs with passive spacers were employed, creating a surface dipole moment that altered the work function (WF) of the electrode. However, recent advancements have led to the synthesis of SAM molecules with active spacers. This development necessitates considering not only the modification of the electrode's WF but also the ionization energy (IE) of the molecule itself. To measure both the IE of SAM molecules and their impact on the electrode's WF, a relatively simple method is photo-electric emission spectroscopy. Solar cell performance parameters have a higher correlation coefficient with the ionization energy of SAM molecules with carbazole derivatives as spacers (up to 0.97) than the work function of the modified electrode (up to 0.88). Consequently, SAMs consisting of molecules with active spacers can be viewed as hole transport layers rather than interface layers.

Characteristics of Multiprofessional and Client-Oriented Approach in Occupational Health Services: A Cross-Sectional Survey Among Occupational Health Professionals.

Background: Multiprofessional and client-oriented approaches are considered key factors for successful occupational health services, and for impressive occupational health cooperation between a client organisation and occupational health service provider. The purpose of this study was to find out the views of occupational health physicians, occupational health nurses, occupational physiotherapists, and occupational health psychologists about multiprofessional and client-oriented working methods. These working methods describe the guidelines for good occupational health practice in Finland, also serving the framework of the present study. Material and Methods: The survey was conducted in May and June 2022. The data consisted of answers to open-ended questions of a larger questionnaire. The data was analysed with the method of theory-related thematic analysis. Seven occupational health service providers committed to the study. Altogether 121 professionals responded to the question surveying the multiprofessional approach, and 119 professionals responded to the question of client-oriented approach. Results: The results showed that both the multiprofessional and client-oriented approaches are closely related to each other, and the views of these approaches are in line with the good occupational health practice. Multiprofessional approach was most commonly described with the theme of sharing expertise. Respectively, the theme of smooth cooperation most commonly described the client-oriented approach. At its best, the answers showed that a multiprofessional working strategy takes into account the expertise of different professionals so that the client can be offered high-quality, accurate content and timely occupational health services. Conclusion: The results provide up-to-date information on working strategies of occupational health services in Finland. The results can be used in further development of multiprofessional and client-oriented work in occupational health services.
