Lifetime and Acute Stress Predict Functional Outcomes Following Stroke: Findings From the Longitudinal STRONG Study

Stroke, Ahead of Print. Background:Stroke is a sudden-onset, uncontrollable event; stroke-related stress may impede rehabilitation and recovery. Lifetime stress may sensitize patients to experiencing greater stroke-related stress and indirectly affect outcomes. We examine lifetime stress as predictor of poststroke acute stress and examine lifetime and acute stress as predictors of 3- and 12-month functional status. We also compare acute stress and baseline National Institutes of Health Stroke Scale as predictors of poststroke functional status.Methods:Between 2016 and 2020 the STRONG Study (Stroke, Stress, Rehabilitation, and Genetics) enrolled adults with new radiologically confirmed stroke 2 to 10 days poststroke onset at 28 acute care US hospitals. Participants were interviewed 3 times: acute admission (acute stress; Acute Stress Disorder Interview), 3 months (Fugl-Meyer Upper Extremity motor impairment [Fugl-Meyer Upper Arm Assessment; N=431], modified Rankin Scale [3 months; N=542], Stroke Impact Scale-Activities of Daily Living [3 months; N=511], Lifetime Stress Exposure Inventory), and 12 months (modified Rankin Scale, N=533; Stroke Impact Scale 3.0 Activities of Daily Living; N=485; Telephone Montreal Cognitive Assessment; N=484) poststroke. Structural equation models examined whether acute stress predicted 3- and 12-month functional outcomes, and mediated an association between lifetime stress and outcomes controlling for demographics and initial National Institutes of Health Stroke Scale. Standardized betas are reported.Results:Sample (N=763) was 19 to 95 years old (mean=63; SD=14.9); 448 (58.7%) were male. Acute stress scores ranged from 0 to 14 (mean, 3.52 [95% CI, 3.31–3.73]). Controlling for age, gender, baseline National Institutes of Health Stroke Scale, and race and ethnicity, higher lifetime stress predicted higher acute stress (β=0.18,P

Study protocol for virtual leisure investigating the effect of virtual reality-delivered stress reduction, entertainment and distraction on the use of coercion and need-based medication and patient satisfaction at a closed psychiatric intensive care unit – a mixed-methods pilot clinical trial

Introduction
The environment at a psychiatric inpatient ward can lead to emotional distress and behavioural deviations in vulnerable individuals potentially resulting in conflicts, increased use of need-based medication and coercive actions, along with low satisfaction with treatment. To accommodate these challenges, recreational and entertaining interventions are recommended. The tested interventions have, however, shown varying effects and demand a high degree of planning and staff involvement while being difficult to adapt to individual needs. Virtual reality (VR) may help overcome these challenges.

Methods and analysis
The study is a mixed-methods clinical trial with a target sample of 124 patients hospitalised at a closed psychiatric ward in the capital region of Denmark. Outcomes (eg, coercion, need-based medication and perceived stress) for a 12-month period where all patients are offered VR-based recreational experiences during their hospitalisation will be compared with outcomes for a 12-month period where VR is not offered. Feasibility and acceptability will be explored with qualitative interviews supplemented with non-participant observations and focus groups. The study began on 1 January 2023, and we expect to complete data collection by 31 December 2024.

Ethics and dissemination
The study is registered at Danish Data Protection Agency (j.no P-2022-466) and is approved by the Committee on Health Research Ethics of the capital region of Denmark (j.no 22013313). All patients will be required to provide informed consent. Results from this study will be disseminated via peer-reviewed journals and congress/consortium presentations.

The role of stress and health behaviour in linking weight discrimination and health: a secondary data analysis in England

Objective
To examine the role of stress and health-risk behaviours in relationships between weight discrimination and health and well-being.

Design
Secondary data analysis of an observational cohort study.

Setting
The English Longitudinal Study of Ageing.

Participants
Data were from 4341 adults (≥50 years) with overweight/obesity.

Primary outcome measures
We tested associations between perceived weight discrimination at baseline (2010/2011) and self-rated health, limiting long-standing illness, depressive symptoms, quality of life and life satisfaction over 4-year follow-up (2010/2011; 2014/2015). Potential mediation by stress exposure (hair cortisol) and health-risk behaviours (smoking, physical inactivity, alcohol consumption) was assessed.

Results
Cross-sectionally, perceived weight discrimination was associated with higher odds of fair/poor self-rated health (OR=2.05 (95% CI 1.49 to 2.82)), limiting long-standing illness (OR=1.76 (95% CI 1.29 to 2.41)) and depressive symptoms (OR=2.01 (95% CI 1.41 to 2.85)) and lower quality of life (B=–5.82 (95% CI –7.01 to –4.62)) and life satisfaction (B=–2.36 (95% CI –3.25 to –1.47)). Prospectively, weight discrimination was associated with higher odds of fair/poor self-rated health (OR=1.63 (95% CI 1.10 to 2.40)) and depressive symptoms (OR=2.37 (95% CI 1.57 to 3.60)) adjusting for baseline status. Those who reported discrimination had higher hair cortisol concentrations (B=0.14 (95% CI 0.03 to 0.25)) and higher odds of physical inactivity (OR=1.90 (95% CI 1.18 to 3.05)). These variables did not significantly mediate associations between discrimination and health outcomes.

Conclusions
Weight discrimination is associated with poor health and well-being. While this discrimination is associated with stress exposure and physical inactivity, these variables explain little of the association between discrimination and poorer outcomes.

Patient preferences for stress urinary incontinence treatments: a discrete choice experiment

Objectives
To elicit and value patient preferences for the processes and outcomes of surgical management of stress urinary incontinence in women.

Design
A discrete choice experiment survey to elicit preferences for type of anaesthesia, postoperative recovery time, treatment success, adverse events, impact on daily activities and cost. An experimental design generated 40 choice tasks, and each respondent completed 1 block of 10 and 2 validity tests. Analysis was by multinomial logistical regression.

Setting
N=21 UK hospitals.

Participants
N=325 adult women who were a subsample of those randomised to the single-incision mini-slings clinical trial.

Outcomes
Patient preferences; valuation obtained using willingness to pay.

Results
N=227 of 325 (70%) returned a questionnaire, and 94% of those completed all choice tasks. Respondents preferred general anaesthesia, shorter recovery times, improved stress urinary incontinence symptoms and avoidance of adverse events. Women were willing to pay (mean (95% CI)) £76 (£33 to £119) per day of reduction in recovery time following surgery. They valued increases in Patient Global Impression of Improvement, ranging from £8173 (£5459 to £10 887) for ‘improved’ to £11 706 (£8267 to £15 144) for ‘very much improved’ symptoms, compared with no symptom improvement. This was offset by negative values attached to the avoidance of complications ranging between £–8022 (£–10 661 to £–5383) and £–10 632 (£–14 077 to £–7187) compared to no complications. Women valued treatments that reduced the need to avoid daily activities, with willingness to pay ranging from £–967 (£–2199 to £266) for rarely avoiding activities to £–5338 (£–7258 to £–3417) for frequently avoiding daily activities compared with no avoidance.

Conclusion
This discrete choice experiment demonstrates that patients place considerable value on improvement in stress urinary incontinence symptoms and avoidance of treatment complications. Trade-offs between symptom improvement and adverse event risk should be considered within shared decision-making. The willingness to pay values from this study can be used in future cost–benefit analyses.

Feasibility of biomarkers to measure stress, burnout and fatigue in emergency nurses: a cross-sectional study

Introduction
Retaining nurses in the workforce is an urgent concern in healthcare. Emergency nurses report high levels of stress and burnout, however, there is no gold standard of how to measure these responses. This study aims to measure stress, burnout, and fatigue in emergency nurses using biomarkers and psychometric instruments. Biomarkers will be used to better understand nurses’ levels of stress and burnout and to assess the feasibility of using biomarkers as a viable stress measurement tool in a real-world setting.

Methods and analysis
A two stage cross-sectional design to measure stress, burnout and fatigue in emergency nurses while they work is proposed. All registered and enrolled nurses working in the emergency department from four hospitals in Australia will be invited to participate. Validated psychometric tools will be used in stage 1 to measure depression, anxiety, acute stress, chronic stress, burnout and fatigue. Biomarkers comprising hair cortisol, saliva alpha amylase and heart rate variability will be collected as an objective measure of stress and burnout in stage 2 over one working shift per participant. Written consent will be sought for stage 2 where nurses will provide one hair sample, wear a heart rate sensor and be asked to collect their saliva at three different time points of one shift. Data analysis will measure the domains of acute stress, chronic stress and burnout and explore relationships and correlation between psychometric measures and biomarkers.

Ethics and dissemination
Ethics approval obtained from the Human Research Ethics Committee of the Hunter New England Local Health District (approval number: HREC/2020/ETH01684) and University of Newcastle HREC (H-2022-0169). Results will be reported in peer-reviewed publications using the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. Public dissemination will occur by presenting at conferences and to the participating local health district.

Stress and safety of maternal and newborn healthcare workers early in the COVID-19 pandemic: a repeat cross-sectional analysis from a global online survey from March 2020 to March 2021

Objectives
This study aims to characterise the physical and psychological well-being of maternal and newborn healthcare workers (MNHCWs) during the COVID-19 pandemic.

Design
Observational repeated cross-sectional study.

Setting
An online questionnaire was distributed to MNHCWs around the globe in three separate rounds from March 2020 to March 2021.

Participants
Total samples of N=1357 (round 1) and N=420 (round 3) primarily consisted of doctors, midwives and nurses in maternal and newborn specialties. Samples represented all WHO regions, with 33% (round 1) and 42% (round 3) from low- or middle-income countries (LMICs).

Primary and secondary outcome measures
Responses from rounds 1 (March–June 2020) and 3 (December 2020–March 2021) were analysed to measure self-reported levels of relative stress and workplace protection from COVID-19, while associated factors were determined through multivariable ordinal logistic regression.

Results
In round 1, 90% of MNHCWs reported increased stress levels and 45% reported insufficient personal protective equipment (PPE) access. Nurses and physicians were less likely to report increased stress than midwives at the pandemic onset. Factors associated with increased stress included being female, being from an LMIC and insufficient PPE. In round 3, 75% reported similar or increased stress while 10% reported insufficient PPE. In both rounds, over 50% of MNHCWs felt relatively or completely unprotected from COVID-19 in the workplace. Those from LMICs were more likely to report feeling unprotected, while receiving organisational information that valued safety was associated with better feelings of protection in the workplace.

Conclusions
Among our international sample of MNHCWs, we observed high rates of self-reported stress increase at the start of the pandemic with persistence or increase up to a year later. High rates of feeling unprotected persisted even as PPE became more available. These results may inform interventions needed to support and protect MNHCWs during this and future pandemics.

Protocol for the COVID-19 Wellbeing and Stress Study: a longitudinal study of parent distress, biological stress and child biopsychosocial development during the pandemic and beyond

Introduction
The COVID-19 pandemic has had a unique impact on the mental health and well-being of pregnant individuals and parents of young children. However, the impact of COVID-19-related stress during pregnancy on early child biopsychosocial development, remains unclear. The COVID-19 Wellbeing and Stress Study will: (1) investigate the impact of different forms of prenatal stress experienced during the pandemic (including objective hardship, perceived psychological distress and biological stress) on child stress biology, (2) examine the association between child stress biology and child developmental outcomes, (3) determine whether child stress biology acts as a mechanism linking prenatal stress to adverse child developmental outcomes and (4) assess whether gestational age at the onset of the COVID-19 pandemic or child sex, moderate these associations.

Methods and analyses
The COVID-19 Wellbeing and Stress Study is a prospective longitudinal study, consisting of six time points, spanning from pregnancy to 3 years postpartum. The study began in June 2020, consisting of 304 pregnant people from Ontario, Canada. This multimethod study is composed of questionnaires, biological samples, behavioural observations and developmental assessments

Ethics and dissemination
This study was approved by the Hamilton Integrated Research Ethics Board (#11034) and the Mount Saint Vincent University Research Ethics Board (#2020-187, #2021-075, #2022-008).

Psychological capital and perceived supervisor social support as mediating roles between role stress and work engagement among Chinese clinical nursing teachers: a cross-sectional study

Objective
This study aimed to investigate the work engagement of clinical nursing teachers and examine whether psychological capital and perceived supervisor social support mediates the association between role stress and work engagement among clinical nursing teachers.

Design
A cross-sectional study design was used.

Setting
This study was conducted in five tertiary hospitals affiliated with medical universities in Shandong Province, China.

Participants
A total of 412 clinical nursing teachers were recruited out of which 406 completed the questionnaires effectively.

Methods
Questionnaires were administered offline and the items consisted of social demographic characteristics, scale related to role stress, psychological capital, perceived supervisor social support and work engagement. T-tests, one-way analysis of variance and Pearson’s correlation analysis were conducted using SPSS, and mediation analysis was performed using structural equation modelling.

Results
The work engagement scores of clinical nursing teachers were high, with an average score of 4.76±0.69. Structural equation modelling showed a good fit of the data to the hypothesised model. Role stress did not directly affect work engagement (β=0.057, p >0.001). However, a strong indirect effect of role stress on work engagement (β=–0.373, p

Co-development of traumatic stress symptoms and externalising behaviour problems among foster children and the effect of complex trauma: a latent growth curve model

Objectives
Foster children are disproportionately exposed to complex trauma, which may lead to multifaceted impairments that manifest in comorbid emotional and behavioural problems. As little is known about the interactions between comorbid disorders over time, the present study aims to explore the co-development of traumatic stress (TS) symptoms and externalising behaviour problems (EBP), as well as the influence of complex trauma operationalised as cumulative child maltreatment (CM).

Setting
As part of a 3-year longitudinal study, children from six foster care facilities in Lower Austria were interviewed at three measurement points.

Participants
Of, in total, 263 participating children, the data of 124 children aged 10–18 years (M=13.5, 28% female) could be analysed.

Primary and secondary outcome measures
Latent growth curve models were used to examine the co-development of TS symptoms (International Trauma Questionnaire) and EBP (Child Behaviour Checklist) over time; gender, age and cumulative CM (Childhood Trauma Questionnaire) acted as time-invariant covariates.

Results
While average TS symptoms decreased over time, EBP remained stable. Findings revealed that the initial severity of EBP was both related to the initial severity of TS symptoms and predictive of their rate of change. Cumulative CM was a significant predictor of initial TS symptoms and EBP even after controlling for age and gender, but not for the rates of change.

Conclusions
Taken together, our results indicate that EBP and TS symptoms are not only cross-sectionally associated but interact with each other over time. Furthermore, an underlying complex trauma could at least partly determine the severity of the two symptom groups. In accordance with a trauma-informed care approach, our study highlights the importance of trauma-specific screening of high-risk children with complex or diffuse symptoms and argues for the benefits of treatments that focus on improving emotion regulation and social skills in addition to addressing trauma.

Exploring physical and biological manifestations of burnout and post-traumatic stress disorder symptoms in healthcare workers: a scoping review protocol

Introduction
The COVID-19 pandemic has strained the mental and physical well-being of healthcare workers (HCW). Increased work-related stress and limited resources have increased symptoms of anxiety, depression, insomnia and post-traumatic stress disorder (PTSD) in this population. Stress-related disorders have been strongly associated with long-term consequences, including cardiometabolic disorders, endocrine disorders and premature mortality. This scoping review aims to explore available literature on burnout, PTSD, and other mental health-associated symptoms in HCW to synthesise relationships with physiological and biological biomarkers that may be associated with increased risk of disease, creating an opportunity to summarise current biomarker knowledge and identify gaps in this literature.

Methods and analysis
This scoping review uses the Arksey and O’Malley six-step scoping review methodology framework. The research team will select appropriate primary sources using a search strategy developed in collaboration with a health sciences librarian. Three reviewers will initially screen the title and abstracts obtained from the literature searches, and two reviewers will conduct independent reviews of full-text studies for inclusion. The research team will be reviewing literature focusing on which burnout and/or PTSD-associated physiological and biological biomarkers have been studied, the methodologies used to study them and the correlations between the biomarkers and HCW experiencing burnout/PTSD. Data extraction forms will be completed by two reviewers for included studies and will guide literature synthesis and analysis to determine common themes.

Ethics and dissemination
This review does not require ethical approval. We expect results from this scoping review to identify gaps in the literature and encourage future research regarding improving biological and physiological biomarker research in HCW. Preliminary results and general themes will be communicated back to stakeholders. Results will be disseminated through peer-reviewed publications, policy briefs and conferences as well as presented to stakeholders to an effort to invest in HCW mental and physical health.

Mind-body exercise interventions for prevention of post-traumatic stress disorder in trauma-exposed populations: a systematic review and meta-analysis

Objective
Mind-body exercise (MBE) interventions, such as yoga, are increasingly recognised as an adjunct treatment for trauma-related mental disorders but less is known about their efficacy as a preventative intervention. We aimed to systematically review if, and what type of, MBE interventions are effective at preventing the development of post-traumatic stress disorder (PTSD) or acute stress disorder (ASD) in trauma-exposed populations.

Design
Systematic review and meta-analysis.

Methods
A systematic search of MEDLINE, PsycINFO, EMBASE and CENTRAL databases was conducted to identify controlled trials of MBE interventions aimed at preventing the development of PTSD or ASD in high-risk populations. Risk of bias was assessed using the revised Cochrane risk-of-bias and ROBINS-I tools. Pooled effect sizes using Hedges’ g and 95% CIs were calculated using random effects modelling for the main meta-analysis and planned subgroup and sensitivity analyses.

Results
Six studies (N analysed=399) were included in the final meta-analysis. Overall, there was a small effect for MBE interventions in preventing the development of PTSD (g=–0.25, 95% CI –0.56 to 0.06) among those with previous or ongoing exposure to trauma. Although a prespecified subgroup analyses comparing the different types of MBE intervention were conducted, meaningful conclusions could not be drawn due to the small number of studies. None of the included studies assessed ASD symptoms.

Conclusion
Limited evidence was found for MBE interventions in reducing PTSD symptomology in the short term. Findings must be interpreted with caution due to the small number of studies and possible publication bias.

Emotional freedom technique versus written exposure therapy versus waiting list for post-traumatic stress disorder: protocol for a randomised clinical MRI study

Introduction
The emotional freedom technique (EFT) is an acupuncture-based psychotherapy that combines tapping on acupoints with cognitive reframing. EFT has been previously shown to have potential for treating post-traumatic stress disorder (PTSD). However, further clinical evidence and underlying mechanisms of EFT are yet to be fully explored. This proposed clinical trial aims to examine the effect of EFT on patients with PTSD compared with the waitlist (WL) and active controls.

Methods and analysis
This study was designed as a randomised, assessor-blinded, three-arm clinical MRI study. A total of 120 eligible patients with PTSD will be recruited and randomised into EFT, written exposure therapy (WET) or WL groups. EFT and WET will be applied once a week for 5 weeks. For patients in the WL group, EFT will be performed after 12 weeks. PTSD symptoms, depression, anxiety, somatic symptoms and quality of life will be evaluated. Assessments will be conducted at baseline (week 0), post-treatment (week 6) and follow-up (week 12). Structural and functional brain images and recording videos of facial expressions to emotional stimuli will be obtained before and after treatment. Sixty participants without lifetime traumatic experiences will be enrolled as healthy controls. The primary objective of the study is to compare the change from baseline in the Clinician-Administered PTSD Scale after treatment (week 6) between EFT and WL groups and between EFT and WET groups.

Ethics and dissemination
Ethical approval was obtained from the Institutional Review Board of the Kyung Hee University Korean Medicine Hospital. The research findings will be shared at national and international conferences and will be published in peer-reviewed journals.
