The Development of Posttraumatic Stress Disorder and Depression Symptoms in Iraqi Refugees: Associations with Acculturation and C-reactive Protein.

ABSTRACT: Refugees experience distress from premigration trauma, often exacerbated by postmigration difficulties. To develop effective interventions, risk factors for mental health symptoms need to be determined. Male Iraqi refugees (N = 53) to the United States provided background information and reported predisplacement trauma and psychological health within 1 month of their arrival. An inflammatory biomarker-C-reactive protein (CRP) was assessed approximately 1.5 years after arrival, and a contextual factor-acculturation-and psychological health were assessed 2 years after arrival. We tested whether acculturation and CRP were associated with posttraumatic stress disorder (PTSD) and depression symptoms at the 2-year follow-up, controlling for baseline symptoms, age, body mass index, and predisplacement trauma. Acculturation was inversely related to depression, and CRP was positively related to both PTSD and depression at the 2-year follow-up. Interventions targeting acculturation could help reduce the development of depression symptoms in refugees. The role of CRP in the development of PTSD and depression symptoms warrants further research.

Neighborhood air pollution and household environmental health as it relates to respiratory health and healthcare utilization among elderly persons with asthma.

Objective: The study investigated the associations between fine particulate matter (PM2.5; <2.5 µm in diameter), indoor environment, pulmonary function, and healthcare utilization in a vulnerable group of elderly persons with asthma. We hypothesized that environmental conditions were associated with adverse pulmonary health outcomes. Methods: The study involved elderly (n = 76; mean age 64.6 years; 48 women) vulnerable persons in Detroit, Michigan, USA, with physician-diagnosed asthma. Exposure variables included measured outdoor PM2.5, self-rated outdoor and household environmental pollutants. Outcome variables were self-rated and measured pulmonary function, and asthma-related healthcare utilization. Results: Mean ambient PM2.5 concentrations during the study was 14.14 ± (S.D. 6.36) µg/m3 during the summer and 14.20 (6.33) during the winter (p = 0.95). In multiple regression analyses, adjusting for age and gender, mean 6-month concentration of PM2.5 was related to shortness of breath (SHOB; standardized ß = 0.26, p = 0.02) and inversely with self-rated respiratory health (SRRH; ß = 0.28, p = 0.02). However, PM2.5 did not predict lung function (FEV1% predicted and FEV1/FVC). However, PM2.5 was related to use of asthma controller drugs (ß = 0.38, p = 0.001). Participants' air pollution ratings predicted total healthcare utilization (ß = 0.33, p = 0.01). Conclusions: In elderly persons with asthma, living near heavy industry and busy highways, objective and perceived environmental pollution relate to participants' respiratory health and healthcare utilization. Importantly, air pollution might increase use of asthma controller drugs containing corticosteroids with implication for elderly persons' risk to develop osteoporosis and cardiovascular disease.

Nurse-Reported Bullying and Documented Adverse Patient Events: An Exploratory Study in a US Hospital.

BACKGROUND: Negative nurse work environments have been associated with nurse bullying and poor nurse health. However, few studies have examined the influence of nurse bullying on actual patient outcomes. PURPOSE: The purpose of the study was to examine the association between nurse-reported bullying and documented nursing-sensitive patient outcomes. METHODS: Nurses (n = 432) in a large US hospital responded to a survey on workplace bullying. Unit-level data for 5 adverse patient events and nurse staffing were acquired from the National Database of Nursing Quality Indicators. Generalized linear models were used to examine the association between bullying and adverse patient events. A Bayesian regression analysis was used to confirm the findings. RESULTS: After controlling for nurse staffing and qualification, nurse-reported bullying was significantly associated with the incidence of central-line-associated bloodstream infections (P < .001). CONCLUSIONS: Interventions to address bullying, a malleable aspect of the nurse practice environment, may help to reduce adverse patient events.

Organizational determinants of bullying and work disengagement among hospital nurses.

AIMS: To identify organizational determinants of bullying and resulting work disengagement among hospital nurses. DESIGN: A cross-sectional, web-based, anonymous questionnaire study. METHODS: The questionnaire was administered in 2017 to all Registered Nurses in a regional healthcare system in the United States (N = 1,780), with 331 complete responses. Logistic regression was used to identify factors associated with personally experiencing and witnessing bullying, respectively. Linear regression was conducted to identify organizational factors associated with disengagement due to bullying. RESULTS: Psychological safety, a measure of team trust and respect, was inversely associated with being personally bullied and witnessing bullying. Being personally bullied, but not witnessing bullying, was associated with disengagement due to bullying. Psychological safety and competence development, a measure of opportunities to develop skills and knowledge at work, were both inversely associated with disengagement due to bullying. CONCLUSION: Hospital units characterized by trust and respect among nurses are less likely to have a culture of bullying. Both psychological safety and competence development have a protective effect on nurse disengagement from the workplace due to bullying. Interventions to mitigate and prevent bullying and work disengagement among nurses should encompass efforts to enhance psychological safety and opportunities for competence development. IMPACT: Bullying is a pervasive hazard in the nursing profession that contributes to unhealthy workplaces. Nurse managers and staff nurses should work together to establish psychologically safe environments where nurses dare to discuss tough issues like bullying. This research contributes to understanding the characteristics of work environments in which nurses can thrive and work effectively.

Workplace Cognitive Failure among Nurses during the COVID-19 Pandemic.

Numerous studies provide evidence of the physical and emotional strain experienced by nurses during the COVID-19 pandemic. However, little is known regarding the impact of this occupational strain on nurses' cognitive function at work. The aim of this study was to identify factors associated with workplace cognitive failure in a sample of U.S. nurses during the COVID-19 pandemic. An online questionnaire was administered in May 2020 to Michigan nurses statewide via three nursing organizations (n = 695 respondents). Path analysis was conducted to test the parallel effects of frequency of contact with COVID patients and personal protective equipment (PPE) supply on workplace cognitive failure scores. Mediation effects of stress, sleep quality, secondary trauma, and work-related exhaustion were examined for each exposure. Results revealed significant indirect effects of all mediators except sleep quality of contact with COVID patients (cumulative indirect effect = 1.30, z = 6.33, p < 0.001) and PPE (cumulative indirect effect = -2.10, z = -5.22, p < 0.001) on cognitive failure. However, 58% of the PPE effect was direct. To reduce the risk of cognitive failure, healthcare organizations need to provide nurses with protective equipment and work environments that allow nurses to strengthen their resilience to extreme working conditions.

Perceptions of virtual primary care physicians: A focus group study of medical and data science graduate students.

BACKGROUND: Artificial and virtual technologies in healthcare have advanced rapidly, and healthcare systems have been adapting care accordingly. An intriguing new development is the virtual physician, which can diagnose and treat patients independently. METHODS AND FINDINGS: This qualitative study of advanced degree students aimed to assess their perceptions of using a virtual primary care physician as a patient. Four focus groups were held: first year medical students, fourth year medical students, first year engineering/data science graduate students, and fourth year engineering/data science graduate students. The focus groups were audiotaped, transcribed verbatim, and content analyses of the transcripts was performed using a data-driven inductive approach. Themes identified concerned advantages, disadvantages, and the future of virtual primary care physicians. Within those main categories, 13 themes emerged and 31 sub-themes. DISCUSSION: While participants appreciated that a virtual primary care physician would be convenient, efficient, and cost-effective, they also expressed concern about data privacy and the potential for misdiagnosis. To garner trust from its potential users, future virtual primary physicians should be programmed with a sufficient amount of trustworthy data and have a high level of transparency and accountability for patients.

Lifestyle and psychosocial factors associated with maintenance of normal body mass index in college students: a cross sectional study.

OBJECTIVES: The purpose of this study was to identify lifestyle and psychosocial factors associated with maintenance of normal body mass index (BMI, 18.5-24.9 kg/m2). Undergraduate students (n = 2781; 7.1% response rate) at a Big Ten university responded to a survey in 2018. BMI was calculated from the reported weight and height at the time of the survey and upon entering the university. Logistic regression analyses examined lifestyle and psychosocial health factors associated with maintenance of normal BMI by academic year. RESULTS: Current BMI was within normal range for 68.8% of freshmen and 60.6% of seniors. Never consuming fast food was a significant predictor for maintaining normal BMI in sophomores (OR 3.78; 95% CI 1.61, 8.88; p < 0.01) and juniors (OR 7.82; 95% CI 2.14, 28.65; p < 0.01). In seniors, better psychosocial health (OR 1.40; 95% CI 1.12, 1.76; p < 0.01) was the only significant predictor for maintaining one's normal freshman BMI category. Among those within the normal BMI range upon entering the university, psychosocial health (OR 1.31; 95% CI 1.10, 1.55; p < 0.01) was the only predictor of retaining one's absolute BMI within ± 3% as a senior. Prospective studies are needed to better understand the interaction between environment, behavior, and psychological health involved in retaining normal weight.

Personal Protective Equipment and Mental Health Symptoms Among Nurses During the COVID-19 Pandemic.

OBJECTIVE: To determine the association between access to adequate personal protective equipment (PPE) and mental health outcomes among a sample of U.S. nurses. METHODS: An online questionnaire was administered in May 2020 to Michigan nurses via three statewide nursing organizations (n = 695 respondents). Multivariable logistic regression analysis was used to identify factors associated with mental health symptoms. RESULTS: Nurses lacking access to adequate PPE (24.9%, n = 163) were more likely to report symptoms of depression (OR 1.96, 95% CI 1.31, 2.94; P = 0.001), anxiety (OR 1.64, 95% CI 1.12, 2.40; P = 0.01) and post-traumatic stress disorder (OR 1.83, 95% CI 1.22, 2.74; P = 0.003). CONCLUSIONS: Healthcare organizations should be aware of the magnitude of mental health problems among nurses and vigilant in providing them with adequate PPE as the pandemic continues.

Enhancing healthcare efficiency to achieve the Quadruple Aim: an exploratory study.

OBJECTIVE: Healthcare is battling a conflict between the Quadruple Aims-reducing costs; improving population health, patient experience, and team well-being-and productivity. This quasi-experimental pilot study tested a 2 week intervention aimed to address the Quadruple Aims while improving productivity. Participants were 25 employees and their patients in a primary care clinic. One provider and their team implemented an efficiency-focused intervention that modified work roles and processes focused on utilizing all team members' skills as allowable by applicable licensure restrictions. The five remaining providers and their teams comprised the reference group, who continued patient care as usual. Study outcomes were measured via provider/staff and patient surveys and administrative data. RESULTS: In total, 46 team surveys and 156 patient surveys were collected. Clinic output data were retrieved for 467 visits. Compared to the reference team, the intervention team performed better in all Quadruple Aims and productivity measures. The intervention group offered 48% more patient slots than the average reference team. These preliminary results support the feasibility of introducing substantial process changes that show promising improvement in both the Quadruple Aims and productivity. A larger-scale study over a longer time period is needed to confirm findings and examine feasibility and cost-effectiveness.

Dysfunctional neuroplasticity in newly arrived Middle Eastern refugees in the U.S.: Association with environmental exposures and mental health symptoms.

BACKGROUND: Psychological war trauma among displaced refugees is an established risk factor for mental health disorders, especially post-traumatic stress disorder (PTSD). Persons with trauma-induced disorders have heightened neuroplastic restructuring of limbic brain circuits (e.g., amygdala and hippocampus), which are critical factors in the pathophysiology of PTSD. Civilians in war are exposed to both psychological trauma and environmental hazards, such as metals. Little is known about the possible mental health impact from such environmental exposures, alone or in combination with trauma. It is of special interest to determine whether war exposures contribute to dysfunctional neuroplasticity; that is, an adverse outcome from sustained stress contributing to mental health disorders. The current study examined Middle Eastern refugees in the United States to determine the relationships among pre-displacement trauma and environmental exposures, brain derived neurotrophic growth factor (BDNF) and nerve growth factor (NGF)-two neurotrophins reported to mediate neuroplasticity responses to stress-related exposures-and mental health. METHODS: Middle Eastern refugees (n = 64; 33 men, 31 women) from Syria (n = 40) or Iraq (n = 24) were assessed 1 month after arrival to Michigan, US. Participants were interviewed in Arabic using a semi-structured survey to assess pre-displacement trauma and environmental exposure, PTSD, depression, anxiety, and self-rated mental health. Whole blood was collected, and concentrations of six heavy metals as well as BDNF and NGF levels were determined. Because these two neurotrophins have similar functions in neuroplasticity, we combined them to create a neuroplasticity index. Linear regression tested whether psychosocial trauma, environmental exposures and biomarkers were associated with mental health symptoms. FINDINGS: The neuroplasticity index was associated with PTSD (standardized beta, ß = 0.25, p < 0.05), depression (0.26, < 0.05) and anxiety (0.32, < 0.01) after controlling for pre-displacement trauma exposures. In addition, pre-displacement environmental exposure was associated with PTSD (0.28, < 0.05) and anxiety (0.32, < 0.05). Syrian refugees and female gender were associated with higher scores on depression (0.25, < 0.05; 0.30, < 0.05) and anxiety scales (0.35, < 0.01; 0.27, < 0.05), and worse on self-rated mental health (0.32, < 0.05; 0.34, < 0.05). In bivariate analysis, the neuroplasticity index was related to blood lead levels (r = 0.40; p < 0.01). CONCLUSIONS: The current study confirms the adverse effects of war trauma on mental health. Higher levels of biomarkers of neuroplasticity correlated with worse mental health and higher blood lead levels. Higher neurotrophin levels in refugees might indicate dysfunctional neuroplasticity with increased consolidation of adverse war memories in the limbic system. Such a process may contribute to psychiatric symptoms. Further research is needed to clarify the pathobiological mechanisms linking war trauma and environmental exposures to adverse mental health.

Nurse Work Environment and Stress Biomarkers: Possible Implications for Patient Outcomes.

OBJECTIVE: To examine associations between nurse work environment, serum biomarkers, and patient outcomes in a large hospital. METHODS: A work environment questionnaire was administered in 2017 to the total sample of nurses in a Midwestern hospital. A subsample of nurses (n = 83) provided blood samples. Correlation analyses examined associations between work environment ratings, biomarkers (dehydroepiandrosterone-sulphate [DHEA-S] and interleukin-6 [IL-6]), and unit-level patient outcomes. RESULTS: Work stress was negatively correlated with DHEA-S (r = -0.23) and positively correlated with IL-6 (r = 0.31; P < 0.05). Psychological safety (r = 0.22) and competence development (r = 0.25) were both positively correlated with DHEA-S (P < 0.05). DHEA-S was negatively correlated with central line-associated bloodstream infections (rho = -0.61; P < 0.05). CONCLUSIONS: Work environment-associated physiological mechanisms might adversely impact patient safety, in addition to nurse health.

The association between attendings' feedback and residents' reporting of near-misses.

OBJECTIVE: Accreditation Council for Graduate Medical Education's Clinical Learning Environment Review report suggests that residents in clinical learning environments underreport their near-misses, an indicator of patient safety. Furthermore, when the residents report these events, they receive little feedback from their attendings. Although, various studies emphasize the importance of feedback given to the residents, the association between feedback and patient safety has not been explored. This study was conducted in 28 emergency medicine residents in a level 1 trauma center. A recent study in the same cohort found that residents' stress biomarker levels and patient acuity were positively related to their near-misses reports. The current study hypothesizes that residents that receive constructive feedback on their performance from their attendings would report more near-misses. RESULTS: Linear regression was used to determine whether ratings of attendings' feedback predicted residents' reports of near-misses. Feedback was positively related to residents' near-misses reports even after controlling for patient acuity and stress biomarker levels. This may be due to the residents becoming more aware of what a near miss is or it may also be that constructive feedback encourages them to report more near-misses as they may view this as a learning opportunity.

Preliminary development of a questionnaire measuring patient views of participation in clinical trials.

OBJECTIVE: This study aimed to develop a questionnaire for measuring patient perceptions of participating in clinical trials. Development was based on earlier research on patient views of involvement in medical care and a literature review. Patients were recruited from an ongoing clinical trial focused on cardiovascular illness and from an outpatient psychiatry department. Factor analysis was conducted on a pilot version of the questionnaire in 2016 and on a revised version in 2017. RESULTS: A total of 53 patients were recruited for the pilot study and 55 were recruited for the main study, substantially below the goal of 100 participants. Factor analysis revealed six factors measuring aspects of patients' perceptions of participating in clinical trials, including motivation, risks and benefits, the nature of the trial itself, and practical considerations, such as cost and convenience. Inter-scale correlations ranged between 0.06 and 0.64, indicating acceptable scale independence. Reliability scores (Cronbach's alphas) ranged from 0.62 to 0.85. Factor analysis results were somewhat unstable, with shared variance for several items across scales. This is likely due to the small sample sizes. In larger, more diverse patient samples, this questionnaire can be useful for measuring and incorporating patients' views into the design and execution of clinical trials.

Organizational Determinants of Workplace Violence Against Hospital Workers.

OBJECTIVE: To identify organizational factors contributing to workplace violence in hospitals. METHODS: A questionnaire survey was conducted in 2013 among employees in a Midwestern hospital system (n = 446 respondents). Questions concerned employees' experiences of violence at work in the previous year and perceptions of the organizational safety climate. Logistic regressions examined staff interaction and safety climate factors associated with verbal and physical violence, respectively. RESULTS: Interpersonal conflict was a risk factor for verbal violence (OR 1.49, 95% CI 1.04 to 2.12, P < 0.05) and low work efficiency was a risk factor for physical violence (OR .98, 0.97 to 0.99). A poor violence prevention climate was a risk factor for verbal (OR 0.48, 0.36 to 0.65, P < .001) and physical (OR 0.60, 0.45 to 0.82, P < .05) violence. CONCLUSIONS: Interventions should aim at improving coworker relationships, work efficiency, and management promotion of the hospital violence prevention climate.

Exposure to intermittent hypoxia and sustained hypercapnia reduces therapeutic CPAP in participants with obstructive sleep apnea.

Our purpose was to determine whether exposure to mild intermittent hypoxia leads to a reduction in the therapeutic continuous positive airway pressure required to eliminate breathing events. Ten male participants were treated with twelve 2-min episodes of hypoxia ([Formula: see text] ≈50 mmHg) separated by 2-min intervals of normoxia in the presence of [Formula: see text] that was sustained 3 mmHg above baseline. During recovery from the last episode, the positive airway pressure was reduced in a stepwise fashion until flow limitation was evident. The participants also completed a sham protocol under normocapnic conditions, which mimicked the time frame of the intermittent hypoxia protocol. After exposure to intermittent hypoxia, the therapeutic pressure was significantly reduced (i.e., 5 cmH2O) without evidence of flow limitation (103.4 ± 6.3% of baseline, P = 0.5) or increases in upper airway resistance (95.6 ± 15.0% of baseline, P = 0.6). In contrast, a similar decrease in pressure was accompanied by flow limitation (77.0 ± 1.8% of baseline, P = 0.001) and an increase in upper airway resistance (167.2 ± 17.5% of baseline, P = 0.01) after the sham protocol. Consistent with the initiation of long-term facilitation of upper airway muscle activity, exposure to intermittent hypoxia reduced the therapeutic pressure required to eliminate apneic events that could improve treatment compliance. This possibility, coupled with the potentially beneficial effects of intermittent hypoxia on comorbidities linked to sleep apnea, suggests that mild intermittent hypoxia may have a multipronged therapeutic effect on sleep apnea.NEW & NOTEWORTHY Our new finding is that exposure to mild intermittent hypoxia reduced the therapeutic pressure required to treat sleep apnea. These findings are consistent with previous results, which have shown that long-term facilitation of upper muscle activity can be initiated following exposure to intermittent hypoxia in humans.
