  • Establishment of reference values for plasma neurofilament light based on healthy individuals aged 5-90 years
  • 2022
  • Ingår i: Brain Communications. - : Oxford University Press (OUP). - 2632-1297. ; 4:4
  • Tidskriftsartikel (refereegranskat)abstract
    • The recent development of assays that accurately quantify neurofilament light, a neuronal cytoskeleton protein, in plasma has generated a vast literature supporting that it is a sensitive, dynamic, and robust biomarker of neuroaxonal damage. As a result, efforts are now made to introduce plasma neurofilament light into clinical routine practice, making it an easily accessible complement to its cerebrospinal fluid counterpart. An increasing literature supports the use of plasma neurofilament light in differentiating neurodegenerative diseases from their non-neurodegenerative mimics and suggests it is a valuable biomarker for the evaluation of the effect of putative disease-modifying treatments (e.g. in multiple sclerosis). More contexts of use will likely emerge over the coming years. However, to assist clinical interpretation of laboratory test values, it is crucial to establish normal reference intervals. In this study, we sought to derive reliable cut-offs by pooling quantified plasma neurofilament light in neurologically healthy participants (5-90 years) from eight cohorts. A strong relationship between age and plasma neurofilament light prompted us to define the following age-partitioned reference limits (upper 95(th) percentile in each age category): 5-17 years = 7 pg/mL; 18-50 years = 10 pg/mL; 51-60 years = 15 pg/mL; 61-70 years = 20 pg/mL; 70 + years = 35 pg/mL. The established reference limits across the lifespan will aid the introduction of plasma neurofilament light into clinical routine, and thereby contribute to diagnostics and disease-monitoring in neurological practice. Simren et al. report age-stratified cut-offs for plasma neurofilament light, based on a large material of healthy individuals across the ages 5-90 years. The findings will assist clinical implementation of plasma neurofilament light in clinical routine, by simplifying interpretation of concentrations across the lifespan as neurofilament light increases with age.

  • Global negative vegetation feedback to climate warming responses of leaf litter decomposition rates in cold biomes
  • 2007
  • Ingår i: Ecology Letters. - : Wiley. - 1461-023X .- 1461-0248. ; 10:7, s. 619-627
  • Tidskriftsartikel (refereegranskat)abstract
    • Whether climate change will turn cold biomes from large long-term carbon sinks into sources is hotly debated because of the great potential for ecosystem-mediated feedbacks to global climate. Critical are the direction, magnitude and generality of climate responses of plant litter decomposition. Here, we present the first quantitative analysis of the major climate-change-related drivers of litter decomposition rates in cold northern biomes worldwide.Leaf litters collected from the predominant species in 33 global change manipulation experiments in circum-arctic-alpine ecosystems were incubated simultaneously in two contrasting arctic life zones. We demonstrate that longer-term, large-scale changes to leaf litter decomposition will be driven primarily by both direct warming effects and concomitant shifts in plant growth form composition, with a much smaller role for changes in litter quality within species. Specifically, the ongoing warming-induced expansion of shrubs with recalcitrant leaf litter across cold biomes would constitute a negative feedback to global warming. Depending on the strength of other (previously reported) positive feedbacks of shrub expansion on soil carbon turnover, this may partly counteract direct warming enhancement of litter decomposition.

  • The role of self-reported stressors in recovery from Exhaustion Disorder: a longitudinal study
  • 2022
  • Ingår i: Bmc Psychiatry. - : Springer Science and Business Media LLC. - 1471-244X. ; 22
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Exhaustion disorder (ED) is a stress-induced disorder characterized by physical and mental symptoms of exhaustion that can be long-lasting. Although stress exposure is essential for the development of ED, little is known regarding the role of stressors in the maintenance of ED. The aim of the study was to investigate the role of work-related stressors, private-related stressors, and adverse childhood experiences in long-term recovery from ED. Methods A mixed methods design was used. The design was sequential, and data analysis was performed in two parts, where the first part consisted of qualitative analysis of patient records, and the second part consisted of statistical analysis of the data retrieved from the qualitative coding. Patient records from 150 patients with ED was analysed regarding work-related stressors, private-related stressors, and adverse childhood experiences. For each patient, two patient records were analysed, one from the time of diagnosis (baseline) and one from the follow-up clinical assessment, 7-12 years after diagnosis (follow-up). Out of the 150 patients, 51 individuals still fulfilled the diagnostic criteria for ED at follow-up (ED group) and 99 individuals no longer fulfilled the diagnostic criteria and were thus considered recovered (EDrec). Percentages in each group (ED and EDrec) reporting each stressor at baseline and follow-up were calculated as well as the differences in percentage points between the groups along with the 95% confidence intervals for the differences. Results At baseline, significantly more EDrec patients reported quantitative demands (73% EDrec, 53% ED) and managerial responsibilities (14% EDrec, 2% ED). Private-related stressors did not differ at baseline. At follow-up, significantly more ED patients reported managerial responsibilities (8 ED, 0% EDrec) and caregiver stress (child) (24% ED, 6% EDrec) and significantly more EDrec patients reported caregiver stress (parent) (6% EDrec, 0% ED). There were no differences regarding adverse childhood experiences. Conclusions The main conclusion is that neither adverse childhood experiences nor any of the stressors at baseline are associated with long-term ED. Ongoing stressors related to having responsibility for other people, such as managerial responsibilities or caring for a child with a chronic disease or psychiatric disorder, may be associated with long-term exhaustion.

  • Resilience Capability and Capacity in Unexpected Crises: Experiences and Lessons Learned in a Healthcare Organisation during the COVID-19 Pandemic
  • 2023
  • Ingår i: Journal of Nursing Management. - 0966-0429 .- 1365-2834.
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim. The current article aims to gain insight into (a) what characterises organisational resilience during an unexpected crisis such as COVID-19 and (b) how organisations respond to developments in their environments. Background. In times of societal crises, such as the COVID-19 pandemic, the resilience of the healthcare organisation is tested. Method. This research is based on a case study in a university hospital and a county hospital in Sweden using surveys with both structured and open answers. Results. The result shows ambiguity and “polarised” experiences, emphasising flexibility vs. structure, clear hierarchical information vs. spaces for peer learning through dialogue, and focus on acute care vs. determination to continue with core operations. Conclusion. The article concludes that the pandemic resulted in paradoxes, tensions, and new experiences in organisational processes and interactions. These create opportunities for learning not only during crises but also for improving nursing management in both acute and planned care. Three relations are important in building organisational resilience in crises: resilience capability, resilience capacity, and sustainable resilience practices. Implications for Nursing Management. Organisational resilience under extraordinary circumstances, such as a pandemic, as well as enhancing the previous literature on nursing management that offer a more individually oriented perspective.

  • Cognitive medicine - a new approach in health care science.
  • 2018
  • Ingår i: BMC psychiatry. - : Springer Science and Business Media LLC. - 1471-244X. ; 18:1
  • Tidskriftsartikel (refereegranskat)abstract
    • The challenges of today's society call for more knowledge about how to maintain all aspects of cognitive health, such as speed/attention, memory/learning, visuospatial ability, language, executive capacity and social cognition during the life course.Medical advances have improved treatments of numerous diseases, but the cognitive implications have not been sufficiently addressed. Disability induced by cognitive dysfunction is also a major issue in groups of patients not suffering from Alzheimer's disease or related disorders. Recent studies indicate that several negative lifestyle factors can contribute to the development of cognitive impairment, but intervention and prevention strategies have not been implemented. Disability due to cognitive failure among the workforce has become a major challenge. Globally, the changing aging pyramid results in increased prevalence of cognitive disorders, and the diversity of cultures influences the expression, manifestation and consequences of cognitive dysfunction.Major tasks in the field of cognitive medicine are basic neuroscience research to uncover diverse disease mechanisms, determinations of the prevalence of cognitive dysfunction, health-economical evaluations, and intervention studies. Raising awareness for cognitive medicine as a clinical topic would also highlight the importance of specialized health care units for an integrative approach to the treatment of cognitive dysfunctions.

  • A Survey of Psychiatric Healthcare Workers' Perception of Working Environment and Possibility to Recover Before and After the First Wave of COVID-19 in Sweden
  • 2021
  • Ingår i: Frontiers in Psychiatry. - : Frontiers Media SA. - 1664-0640. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: This study aimed to investigate the impact of the first wave of the COVID-19 pandemic on perceived working environment, including the possibility to recover, among psychiatric healthcare workers (PHCWs) in comparison with pre-pandemic measures. Method: A link to an anonymous, web-based COVID-19 related survey was sent via email to all PHCWs at a university hospital in Sweden (n = 1,618) in September 2020. The response rate was 38% (566 of 1,507 eligible participants). Working environment survey responses collected in 2019 were used as pre-pandemic comparators. Statistical analyses were performed to assess overall impact over time on work demands, support, motivation, and recovery, stratified by professional role, and considering variables such as access to personal protective equipment. Results: The percentage of individuals responding negatively to statements about working environment increased significantly for most items after the first wave. Similarly, the increase of five of the investigated factors indicated a more negative perception of recovery during the pandemic. Registered nurses reported a greater negative impact of the pandemic on perceived working conditions and ability to recover than other professional groups. PHCWs working with patients with COVID-19 (35%) who reported being worried about becoming infected (12%) or infecting others (17%), or lacking adequate personal protective equipment (22%) were more negatively impacted regarding work environment-related items than those who did not. Conclusions: PHCWs' working environment and possibility for recovery were impacted by the first wave of the COVID-19 pandemic, nurses being most affected. Although psychiatric services do not directly care for patients with severe COVID-19 infection, the results from this study suggests that mental health services should also prepare for future pandemics.

  • Worry perception and its association with work conditions among healthcare workers during the first wave of the COVID-19 pandemic: a web-based multimethod survey at a university hospital in Sweden.
  • 2024
  • Ingår i: BMJ open. - 2044-6055. ; 14:2
  • Tidskriftsartikel (refereegranskat)abstract
    • In this study, we explored healthcare workers' (HCWs) worry perception and its association with their work situation during the first wave of the COVID-19 pandemic.A web-based multimethods survey including multiple choice and open-ended questions was used.The study was conducted at a university hospital in Sweden.All HCWs who were working during the first wave of the COVID-19 pandemic in March-June 2020 were eligible. HCWs (n=6484, response rate=41%) from 69 departments fulfilled the study inclusion criteria and responded to the survey. Of them, we analysed data from the 3532 participants who replied to the open-ended questions (54% of the respondents).Worry perception and its association with work conditions among HCWs.29% (n=1822) and 35% (n=2235) of the responding HCWs experienced a daily or more than daily strong worry of being infected or infecting others with SARS-CoV-2. This finding could be further confirmed and explored with themes from the qualitative results: 'ambiguity of feeling safe and secure', 'being obliged to adapt to a new reality' and 'into the unknown'. The themes consisted of 6 main categories and 15 subcategories. The findings revealed that the two main drivers of worry perceived by HCWs were lack of personal protective equipment and fear of bringing the virus home to their families and friends.Worries of getting infected are common among HCWs during crises such as the COVID-19 pandemic. Several factors are raised that plausibly could minimise the negative effects of worry among HCWs. Thus, effective preventive work plans should be created, promoted and communicated in order to minimise the effects of such crises and support HCWs. By focusing on effective communication and preparedness, including access to relevant protective equipment and providing general support to HCWs, the work environment and patient care could be sustained during a crisis such as the COVID-19 pandemic.

  • Effectiveness of a person-centred eHealth intervention in reducing symptoms of burnout in patients with common mental disorders - secondary outcome analysis of a randomized controlled trial
  • 2023
  • Ingår i: Bmc Primary Care. ; 24:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background The number of people with common mental disorders (CMDs), especially stress-related disorders, has increased in several countries, including Sweden, during the past decade. Patients seeking care for long-term stress report severe symptoms. Although person-centred care (PCC) has shown several benefits, studies evaluating the effects of a PCC eHealth intervention on patients with CMDs are scarce.Objective The aim of this study was to compare levels of self-reported symptoms of burnout between a control group receiving treatment as usual (TAU) and an intervention group receiving TAU with the addition of a person-centred eHealth intervention, in patients on sick leave for CMDs.Methods This study reports analysis of a secondary outcome measure from a randomized controlled trial. Patients (n = 209) on sick leave for CMDs were recruited from nine primary health care centres and allocated to either a control group (n = 107) or an intervention group (n = 102). The intervention consisted of phone support and an interactive digital platform built on PCC principles. Self-reported symptoms of burnout were assessed using the Shirom-Melamed Burnout Questionnaire (SMBQ) at baseline and at 3 and 6 months.Results Our findings showed changes in SMBQ scores over time in both the control and the intervention group. There was no significant difference in SMBQ scores between the groups; however, a difference in change over time between the groups was observed. The SMBQ scores decreased significantly more in the intervention group than in the controls between 0 and 3 months and between 0 and 6 months. No differences in change between the two groups were seen between the 3- and 6-month follow-ups.Conclusion This person-centred eHealth intervention for patients on sick leave for CMDs showed a slight initial effect in reducing symptoms of burnout. Taking into account that both groups reported comparable SMBQ scores throughout the study period, the overall effect may be considered limited.

  • The effects of exercise training on hypothalamic-pituitary-adrenal axis reactivity and autonomic response to acute stress-a randomized controlled study
  • 2020
  • Ingår i: Trials. - : Springer Science and Business Media LLC. - 1745-6215. ; 21:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BackgroundExercise training is suggested to have a stress-buffering effect on physiological reactions to acute stress. The so-called cross-stressor adaptation hypothesis is one of many theories behind the plausible effects, proposing that the attenuated physiological reaction seen in trained individuals in response to acute exercise is also seen when the individual is exposed to acute psychosocial stress. However, few randomized controlled trials (RCT) are available in this field. Therefore, the aim of the present trial was to study the effects of a 6-month aerobic exercise intervention on the physiological response to acute laboratory stress.MethodsA two-armed RCT including untrained but healthy individuals aged 20-50years was conducted. Assessments included a peak oxygen uptake test and a psychosocial stress test (the Trier Social Stress Test). A total of 88 participants went through both baseline and follow-up measures (48 in the intervention group and 40 in the control group) with a similar proportion of women and men (20 women and 28 men in the intervention group and 18 women and 22 men in the control group). Outcome measures were adrenocorticotrophic hormone, cortisol, systolic and diastolic blood pressure, and heart rate responses to acute psychosocial stress.ResultsOxygen uptake and time-to-exhaustion increased significantly following the intervention, while a decrease was seen in the control group. The analyses showed attenuated responses to acute psychosocial stress for all variables in both groups at follow-up, with no differences between the groups. No correlation was seen between amount of exercise training and reactivity to the stress test. Despite the increased oxygen uptake in the intervention group, no differences were seen between the groups for any of the outcome variables at follow-up.ConclusionsIn this study, the cross-stressor adaptation hypothesis could not be confirmed. Both groups showed decreased reactions indicating a habituation to the stress test.Trial registrationClinicalTrials.gov NCT02051127. Registered on 31 January 2014-retrospectively registered.

  • The level of leisure time physical activity is associated with work ability-a cross sectional and prospective study of health care workers
  • 2013
  • Ingår i: Bmc Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 13:855
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: With increasing age, physical capacity decreases, while the need and time for recovery increases. At the same time, the demands of work usually do not change with age. In the near future, an aging and physically changing workforce risks reduced work ability. Therefore, the impact of different factors, such as physical activity, on work ability is of interest. Thus, the aim of this study was to evaluate the association between physical activity and work ability using both cross sectional and prospective analyses. Methods: This study was based on an extensive questionnaire survey. The number of participants included in the analysis at baseline in 2004 was 2.783, of whom 2.597 were also included in the follow-up in 2006. The primary outcome measure was the Work Ability Index (WAI), and the level of physical activity was measured using a single-item question. In the cross-sectional analysis we calculated the level of physical activity and the prevalence of poor or moderate work ability as reported by the participants. In the prospective analysis we calculated different levels of physical activity and the prevalence of positive changes in WAI-category from baseline to follow-up. In both the cross sectional and the prospective analyses the prevalence ratio was calculated using Generalized Linear Models. Results: The cross-sectional analysis showed that with an increased level of physical activity, the reporting of poor or moderate work ability decreased. In the prospective analysis, participants reporting a higher level of physical activity were more likely to have made an improvement in WAI from 2004 to 2006. Conclusions: The level of physical activity seems to be related to work ability. Assessment of physical activity may also be useful as a predictive tool, potentially making it possible to prevent poor work ability and improve future work ability. For employers, the main implications of this study are the importance of promoting and facilitating the employees' engagement in physical activity, and the importance of the employees' maintaining a physically active lifestyle.

  • Exercise training and physiological responses to acute stress: study protocol and methodological considerations of a randomised controlled trial
  • 2018
  • Ingår i: BMJ Open Sport & Exercise Medicine. - : BMJ. - 2055-7647. ; 4:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: This paper describes the protocol and methodological prerequisites for a randomised controlled exercise intervention. Selected baseline data from the study are also presented, demonstrating some methodological challenges related to exercise intervention trials. The aim of the trial was to study the effects of exercise training on physiological responses to acute psychosocial stress in untrained individuals. Methods: Individuals with a low level of physical activity were invited to participate in an exercise intervention lasting for 6 months. A total of 119 participants were included and went through a peak oxygen uptake test and a psychosocial stress test at baseline. Adrenocorticotropic hormone (ACTH) and cortisol were measured in connection to the stress test to identify the physiological response. Results: Almost 90% of the participants reported themselves as untrained, but results from the objectively measured oxygen uptake did not seem to correspond to the reported sedentary lifestyle. The primary outcome measures at baseline varied between individuals. The mean change from pre-test to peak value was 214% for ACTH and 94% for cortisol. Of these, 13 individuals did not respond in ACTH and/or and cortisol. Discussion: Supposedly untrained individuals seeking participation in an exercise intervention might not be as untrained as they report, a methodological consideration of importance when evaluating the effects of training. Another important consideration is related to the primary outcome measure, which should be measurable and possible to affect. Absence of reaction at baseline means that changes can only be detected as an increased reaction.

  • Self-reported changes in work situation – a cross-sectional study of patients 7 years after treatment for stress-related exhaustion
  • 2021
  • Ingår i: BMC Public Health. - : Springer Science and Business Media LLC. - 1471-2458. ; 21:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Exhaustion disorder (ED) is a common cause of sick leave in Sweden, and patients often have long-lasting symptoms and reduced work capacity. The aim of this study was to explore whether patients with ED had made any changes in their work situation from the period of treatment and up to 7 years later. Methods: In this cross-sectional study, patients diagnosed with ED at a specialist outpatient clinic were followed up after 7 years (n = 217). They received questionnaires at baseline covering sex, age, marital status, level of education, and symptoms of burnout, depression, and anxiety measured with the Shirom-Melamed Burnout Questionnaire and the Hospital Anxiety and Depression Scale. After 7 years, they were sent a follow-up questionnaire asking about their work situation and work-related stressors both before they fell sick and at the 7-year follow-up. There were three questions on work situation (change of workplace, change of work tasks, and change of working hours), and 155 patients responded to all three. Results: After 7 years, the majority of the patients (63%; n = 98/155) reported that they had made some kind of change at work. Women were more likely than men to report decreased working hours (p = 0.001), and work-related stressors such as conflicts at work, reorganization, deficient leadership, and general discontent with the work situation were significantly more common at baseline in the group who had made changes at work. Patients who made no changes at work experienced more work-related stress due to quantitative demands in the 7-year follow-up. Conclusion: The majority of the patients with ED made some kind of change in their work situation, and gender differences were found for changes of work tasks and working hours. Work-related stressors might be decisive for making changes at work. © 2021, The Author(s).

  • Under pressure - The working situation of Swedish healthcare managers during the first wave of COVID-19
  • 2023
  • Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 13
  • Tidskriftsartikel (refereegranskat)abstract
    • IntroductionThe aim of this study is to provide insight into the psychosocial work situation of hospital managers during the first wave of the COVID-19 pandemic. MethodsMixed-effect modelling was used on survey data on job demands, job resources, job motivation, and work-life balance among over 500 managers working in 55 departments of a large Swedish university hospital in 2019 and 2020. Responses from 6011 employees were then used to stratify the analysis for COVID-19 exposure. Inductive content analysis was applied to open-ended questions on the managers' views on organisational prerequisites during the onset of the pandemic. ResultsThe proportion of managers reporting difficulties with role clarity, quantitative demands, decision-making authority, and emotional support, time for recovery at work, motivation deficits, or problems with work-life balance clearly increased during the first wave of the pandemic. The proportion of managers reporting negative responses was higher in departments with high COVID-19 exposure. The qualitative analysis shows that overall governance in terms of clear, fair, and well-communicated routines, resource allocation, and division of responsibilities constituted an important framework for managerial during the crisis. First-line managers also require a mandate to re-organize their roles and their teams to successfully adapt to the situation. Organisational and social support was also important resources. DiscussionThis is the first study investigating healthcare managers' work situation during the first wave of the COVID-19 pandemic in a Swedish context. As expected, it indicates an increasingly strained work situation during the crisis, but it also provides findings on organisational prerequisites that allow healthcare managers to cope with stressful situations. In line with previous research on organisational resilience, the study provides suggestions for how higher-level managers can act in order to provide front-line managers with the organisational prerequisites they need to adapt, learn and develop successfully during times of unpredictability, insecurity, and rapid change in order to offer the best possible support to health care workers.

    • To investigate whether intensified cooperation between general practitioner (GP), care manager and rehabilitation coordinator (RC) for patients sick-listed for stress-related mental disorder, combined with a person-centred dialogue meeting with employer, could reduce sick-leave days compared with usual care manager contact.Pragmatic cluster-randomised controlled trial, randomisation at primary care centre (PCC) level.PCCs in Region Västra Götaland, Sweden, with care manager organisation.Of 30 invited PCCs, 28 (93%) accepted the invitation and recruited 258 patients newly sick-listed due to stress-related mental disorder (n=142 intervention, n=116 control PCCs).Cooperation between GP, care manager and rehabilitation coordinator from start of illness notification plus a person-centred dialogue meeting between patient and employer within 3months. Regular contact with care manager was continued at the control PCCs.12-months net and gross number of sick-leave days. Secondary outcomes: Symptoms of stress, depression, anxiety; work ability and health related quality of life (EQ-5D) over 12months.There were no significant differences between intervention and control groups after 12months: days on sick-leave (12-months net sick-leave days, intervention, mean = 110.7days (95% confidence interval (CI) 82.6-138.8); control, mean = 99.1days (95% CI 73.9-124.3)), stress, depression, or anxiety symptoms, work ability or EQ-5D. There were no significant differences between intervention and control groups concerning proportion on sick-leave after 3, 6, 12months. At 3months 64.8% were on sick-leave in intervention group vs 54.3% in control group; 6months 38% vs 32.8%, and12 months 16.9% vs 15.5%.Increased cooperation at the PCC between GP, care manager and RC for stress-related mental disorder coupled with an early workplace contact in the form of a person-centred dialogue meeting does not reduce days of sick-leave or speed up rehabilitation.Trial registration: ClinicalTrials.gov Identifier: NCT03250026 https://clinicaltrials.gov/study/NCT03250026?tab=results#publicationsCO-WORK-CAREFirst Posted: August 15, 2017.

  • Evidence for an adrenergic innervation of the adrenal cortical blood vessels in rats.
  • 1993
  • Ingår i: Acta physiologica Scandinavica. - 0001-6772. ; 149:1, s. 23-30
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to investigate the blood flow in the adrenal cortex of the rat. Relative changes in the adrenal cortical blood flow were continuously measured by Laser Doppler flowmetry in 33 chloralose-anaesthetized artificially ventilated rats during electrical stimulation (1 ms, 5 V) of the left great splanchnic nerve (LGSN), which conveys both pre- and post-ganglionic nerve fibres to the adrenal gland. Laser Doppler flux (LDF) was decreased and regional resistance (RR) was increased by augmenting nerve stimulation at increasingly higher frequencies (2, 4, 8, 20 and 40 Hz). The decrease in LDF, when compared to pre-drug stimulations at 4 Hz was partially or totally inhibited by the adrenergic blocking agents trimethaphan (TRIM), guanethidine (GUA) and alpha 1-blockade with prazosin (PRAZ). Furthermore, both the decrease in LDF and the increase in RR were either completely or partially blocked by stimulation at 40 Hz after TRIM-treatment and GUA-treatment. It is concluded that the adrenal cortex in the rat is innervated by post-ganglionic adrenergic nerve fibres, which are involved in the regulation of blood flow in the adrenal cortex.

  • Effects of a Person-Centered eHealth Intervention for Patients on Sick Leave Due to Common Mental Disorders (PROMISE Study): Open Randomized Controlled Trial
  • 2022
  • Ingår i: Jmir Mental Health. - : JMIR Publications Inc.. - 2368-7959. ; 9:3
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Sick leave due to common mental disorders (CMDs) is a public health problem in several countries, including Sweden. Given that symptom relief does not necessarily correspond to return to work, health care interventions focusing on factors that have proven important to influence the return to work process, such as self-efficacy, are warranted. Self-efficacy is also a central concept in person-centered care. Objective: The aim of this study is to evaluate the effects of a person-centered eHealth intervention for patients on sick leave due to CMDs. Methods: A randomized controlled trial of 209 patients allocated to either a control group (107/209, 51.2%) or an intervention group (102/209, 48.8%) was conducted. The control group received usual care, whereas the intervention group received usual care with the addition of a person-centered eHealth intervention. The intervention was built on person-centered care principles and consisted of telephone support and a web-based platform. The primary outcome was a composite score of changes in general self-efficacy (GSE) and level of sick leave at the 6-month follow-up. An intention-to-treat analysis included all participants, and a per-protocol analysis consisted of those using both the telephone support and the web-based platform. Results: At the 3-month follow-up, in the intention-to-treat analysis, more patients in the intervention group improved on the composite score than those in the control group (20/102, 19.6%, vs 10/107, 9.3%; odds ratio [OR] 2.37, 95% CI 1.05-5.34; P=.04). At the 6-month follow-up, the difference was no longer significant between the groups (31/100, 31%, vs 25/107, 23.4%; OR 1.47, 95% CI 0.80-2.73; P=.22). In the per-protocol analysis, a significant difference was observed between the intervention and control groups at the 3-month follow-up (18/85, 21.2%, vs 10/107, 9.3%; OR 2.6, 95% CI 1.13-6.00; P=.02) but not at 6 months (30/84, 35.7%, vs 25/107, 23.4%; OR 1.8, 95% CI 0.97-3.43; P=.06). Changes in GSE drove the effects in the composite score, but the intervention did not affect the level of sick leave. Conclusions: A person-centered eHealth intervention for patients on sick leave due to CMDs improved GSE but did not affect the level of sick leave.

  • Tidskriftsartikel (refereegranskat)abstract
    • INTRODUCTION: The number of people dealing with common mental disorders (CMDs) is a major concern in many countries, including Sweden. Sickness absence resulting from CMDs is often long-lasting and advancing return to work is a complex process impacted by several factors, among which self-efficacy appears to be an important personal resource. Person-centred care (PCC) has previously shown positive effects on self-efficacy however this needs to be further investigated in relation to patients with CMDs and in an eHealth context. METHODS AND ANALYSIS: This study is an open randomised controlled trial comparing a control group receiving standard care with an intervention group receiving standard care plus PCC by telephone and a digital platform. The primary outcome measure is a composite score of changes in sick leave and self-efficacy. Participants will include 220 primary care patients on sick leave due to CMDs and data will mainly be collected through questionnaires at baseline and 3, 6, 12 and 24 months from the inclusion date. Inclusion is ongoing and expected to be completed during the fall of 2020. A process and health economic evaluation will also be conducted. ETHICS AND DISSEMINATION: This study was approved by the Regional Ethical Review Board in Gothenburg, Sweden. Results will be published in peer-reviewed scientific journals and presented at national and international scientific conferences. This project is part of a broader research programme conducted at the Gothenburg Centre for Person-Centred Care (GPCC), where extensive work is undertaken to disseminate knowledge on and implementation of PCC. TRIAL REGISTRATION NUMBER: NCT03404583.

  • Psychologists' involvement in and experiences of treating patients with stress-related exhaustion in primary care.
  • 2024
  • Ingår i: BMC Primary Care. - : Springer Nature. - 2731-4553. ; 25:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Primary health care is the setting for most patients with stress-related mental health problems. Good care processes are important for patients with stress-related mental health problems and the complex needs of these patients has become a challenge for primary care settings which is traditionally designed to manage acute episodes of one illness. The care process of these patients is thus interesting to investigate. The aim of this study was to explore psychologists´ involvement and experiences regarding the organisation of the care process and treatment of patients seeking care for stress-related exhaustion.METHOD: Fifteen psychologists (14 women and 1 man, age range 27-72 years)c from fifteen different primary health care centres in the western part of Sweden, located in both rural and urban areas were included. Qualitative content analysis of individual semi-structured interviews was conducted.RESULTS: The analysis resulted in eight subcategories within the two main categories studied illuminating psychologists' involvement and experiences regarding the organisation of the care process and challenges regarding treatment of patients seeking care for stress-related exhaustion.CONCLUSION: The care process of patients with stress-related exhaustion is perceived to be ineffective and not congruent with the needs of the patients. A lack of holistic overview of the care process, a lack of collaboration and poor utilization of the health care professionals' competence leads to an unstructured process forcing the patients to be the carriers and coordinators of their own care.

  • Self-reported cognitive impairment and daily life functioning 7-12 years after seeking care for stress-related exhaustion
  • 2021
  • Ingår i: Scandinavian Journal of Psychology. - : Wiley. - 0036-5564 .- 1467-9450. ; 62:4, s. 484-492
  • Tidskriftsartikel (refereegranskat)abstract
    • The overall aim of this study was to investigate self-reported cognitive difficulties, daily life activities, and health/sleep factors in former patients with exhaustion disorder (ED) who still fulfill the clinical criteria for exhaustion 7-12 years after seeking care. The Sahlgrenska Self-reported Cognitive Impairment Questionnaire (SASCI-Q) was used to measure cognitive difficulties, daily life activities, and health/sleep factors. Three groups were compared: previous patients still judged to be clinically exhausted seven years or more after seeking care (n = 51); previous patients considered clinically recovered (n = 98); and healthy controls (n = 50). Patients who still fulfilled the diagnostic criteria for ED reported widespread problems related to cognition, fatigue, and daily life functioning compared to the clinically recovered group. Furthermore, despite no longer fulfilling the clinical criteria, the recovered patients still reported more problems related to cognitive functioning and fatigue compared to healthy controls. Thus, this group appeared intermediary between the non-recovered group and healthy controls regarding self-reported cognitive functioning. To conclude, ED may have considerable negative long-term effects, and it is possible that some of these residual symptoms, particularly the cognitive problems and persistent fatigue, are permanent in some patients. Preventive measures should be the primary focus for all stakeholders, since the consequences of stress-related mental health problems seem to be extensive and long-lasting.

  • Ingår i: Frontiers in Psychology. - : Frontiers Media SA. - 1664-1078. ; 12
  • Tidskriftsartikel (refereegranskat)abstract
    • Aim: To achieve a deeper understanding of the patient's perception regarding individual aspects related to the development of exhaustion, hindering and supporting factors in the recovery process, and potential remaining consequences, 7-12 years after receiving an exhaustion disorder diagnosis.Participants and Methods: Twenty patients previously diagnosed with and treated for exhaustion disorder were interviewed 7-12 years after onset of the disease. The semi-structured interviews were transcribed verbatim and analyzed with inductive content analysis.Results: Three main themes with patterns of shared meaning resulted from the analysis: "it's about who I am," "becoming a more authentic me," and "the struggle never ends." The interviewees described rehabilitation from exhaustion disorder as the start of an important personal development toward a truer and more authentic self-image. They perceived this as an ongoing long-lasting process where learned behavior and thought patterns related to overcommitment and overcompliance needed to be re-evaluated. The results also convey long-term consequences such as cognitive difficulties and reduces energy, uncertainty about one's own health, and the need to prioritize among one's relationships.Conclusion: Patients with exhaustion disorder are still struggling with dysfunctional strategies and functional impairments such as cognitive problems which limit their lives, 10 years after receiving their exhaustion disorder diagnosis. While informants describe some positive consequences of ED, the results also emphasize the importance of acknowledging that the patients are embedded in systems of relationships, in working life as well as in family life. This needs to be considered, together with other aspects, when working toward prevention of stress-related mental health problems.

  • The single-item measure of stress after myocardial infarction and its association with fatigue
  • 2015
  • Ingår i: Open Journal of Nursing. - : Scientific Research Publishing, Inc.. - 2162-5336 .- 2162-5344. ; 5:4, s. 345-353
  • Tidskriftsartikel (refereegranskat)abstract
    • Surviving a myocardial infarction (MI) can be a stressful event entailing challenges in daily life during the recovery period. Experiencing fatigue symptoms post-MI has been described as bothersome and occurs in nearly half of patients four months and two years after MI. The aetiology of fatigue disorder is unclear, but research has shown that fatigue plays an important role in the relationship between stress and perceived poor health. Previous findings indicate that having access to an easily administered stress measurement is worthwhile both in the clinic and in research. The single-item measure of stress symptoms has not been validated in persons treated for MI. The aim was to validate the single-item measure of stress symptoms and to explore its association with fatigue in a sample of persons treated for MI. Methods: 142 respondents completed the questionnaires of the Multidimensional Fatigue Inventory-20, the single-item measure of stress symptoms and the Perceived Stress Scale-10 (PPS-10) two months post-MI. Correlation analysis and t-tests were used to validate the single-item stress measure and its association with post-MI fatigue. Results: The convergent validity of the single-item measure of stress symptoms was confirmed. In analyses of relations between stress and fatigue, it was found that the single-item stress measure was strongly associated with both the global fatigue score and all four fatigue dimension scores (general, physical and mental fatigue as well as reduced activity). Conclusion: The single-item measure of stress symptoms was found to be a valid measure of post-MI stress. Also, the measure was useful in assessing associations between stress and fatigue and could therefore indicate that post-MI fatigue experiences should be further explored in full using multidimensional fatigue assessment.

  • Ingår i: Sleep Medicine. - : Elsevier. - 1389-9457 .- 1878-5506. ; 69, s. 189-197
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To increase our understanding of patterns of change in physical activity and sleep complaints and to test whether intra-individual changes in physical activity are correlated with intra-individual changes in sleep complaints across four measurement time-points over six years, adopting both a between-person and within-person perspective.METHODS: Data from a longitudinal cohort study were used in this research. At baseline, 3187 participants took part in the study (86% women, Mage = 46.9 years). The response rate was 84% (n = 3136) after two years, 60% (n = 2232) after four years, and 40% (n = 1498) after six years. Physical activity was assessed with the [51] widely used 4-level physical activity scale (SGPALS), and sleep complaints with three items from the Karolinska Sleep Questionnaire (KSQ). Patterns and correlations of change between physical activity and sleep complaints were examined with latent growth curve modeling.RESULTS: Changes in physical activity were associated with changes in sleep complaints across the six years. More specifically, significant associations occurred between baseline levels, correlated (between-person) change, and coupled (within-person change). These associations indicate that higher physical activity levels are not only cross-sectionally linked with fewer sleep complaints, but that increases in physical activity over time (either in comparison to others or to oneself) are paralleled by decreases in sleep complaints.CONCLUSIONS: Given that changes in physical activity and sleep are correlated, our findings indicate that it is worthwhile to initiate more physically active lifestyles in physically inactive individuals; and to ensure that those who are already physically active maintain their physical activity levels over longer periods.

    • OBJECTIVE: To examine how cardiorespiratory fitness and self-perceived stress are associated with burnout and depression. To determine if any relationship between stress and burnout/depression is mitigated among participants with high fitness levels.METHODS: 197 participants (51% men, mean age=39.2 years) took part in the study. The Åstrand bicycle test was used to assess cardorespiratory fitness. Burnout was measured with the Shirom-Melamed Burnout Questionnaire (SMBQ), depressive symptoms with the Hospital Anxiety and Depression Scale (HAD-D). A gender-matched stratified sample was used to ensure that participants with varying stress levels were equally represented.RESULTS: Participants with moderate and high fitness reported fewer symptoms of burnout and depression than participants with low fitness. Individuals with high stress who also had moderate or high fitness levels reported lower scores on the SMBQ Tension subscale and the HAD-D than individuals with high stress, but low fitness levels.CONCLUSION: Better cardiovascular fitness seems to be associated with decreased symptoms of burnout and a better capacity to cope with stress.PRACTICAL IMPLICATIONS: Promoting and measuring cardiorespiratory fitness can motivate employees to adopt a more physically active lifestyle and thus strengthen their ability to cope with stress exposure and stress-related disorders.

  • Concerns regarding hair cortisol as a biomarker of chronic stress in exercise and sport science
  • 2012
  • Ingår i: Journal of Sports Science and Medicine. - 1303-2968. ; 11, s. 571-581
  • Forskningsöversikt (refereegranskat)abstract
    • Hair cortisol has the potential to fill the methodological void of long-term cortisol assessment while becoming a widely accepted measure in biopsychology. This review critically examines the applicability and relevance of hair cortisol measurement specifically within the field of exercise and sport science. Current measures of the HPA axis only cover a brief time period, whereas hair cortisol is a unique, non-invasive means to capture long-term cortisol secretion. Studies have shown that individuals who have elevated cortisol secretion (e.g. due to diseases associated with a disturbed activation of the HPA axis or exposure to stressful life events) reveal increased hair cortisol. By contrast, only weak correlations exist between hair cortisol and perceived stress, and the direction of the relationship between hair cortisol levels and mental disorders is unclear. Acute exercise, however, results in increased levels of cortisol that eventually is reflected in higher levels of cortisol in hair samples and studies have shown that exercise intensity is related to hair cortisol level. Thus, elevated hair cortisol levels found among regular exercisers are not necessarily pathological. Thus, one should practice caution when associating athletes’ elevated hair cortisol with poor mental health or disease. Hair cortisol analysis can contribute to a more complete understanding of how long-term cortisol elevation mediates stress-related effects on the health and performance of recreational exercisers and elite athletes. Nevertheless, it is crucial for exercise and sport scientists to consider whether their research questions can be adequately addressed, given that regular intense exercise results in substantially augmented hair cortisol levels.

  • Fitness Moderates the Relationship between Stress and Cardiovascular Risk Factors
  • 2016
  • Ingår i: Medicine and Science in Sports and Exercise. - : Ovid Technologies (Wolters Kluwer Health). - 0195-9131. ; 48:11, s. 2075-2081

    • Purpose This cross-sectional observational study examined the degree to which cardiorespiratory fitness (CRF) and self-perceived stress are associated with cardiometabolic risk factors and the overall risk score for cardiovascular diseases. The second aim was to determine whether participants' CRF levels moderate the relationships between stress and cardiometabolic risk. Methods A gender-matched stratified sample (N = 197, 51% men, M-age = 39.2 yr) was used to ensure that participants with varying stress levels were equally represented. CRF was assessed with the angstrom strand bicycle test, and perceived stress was assessed with a single-item question. Systolic blood pressure (SBP) and diastolic blood pressure (DBP), body mass index (BMI), total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol (LDL-C), triglycerides (TG), glycated hemoglobin, and total cardiometabolic risk score (sum of the z-standardized residuals of the previously mentioned indicators) were assessed as outcomes. Results Higher LDL-C, TG, and total metabolic risk were found in participants with high stress scores (P < 0.05). In addition, lower SBP, DBP, BMI, LDL-C, TG, and total metabolic risk were observed in participants with high CRF (P < 0.05). Two-way ANCOVA provided significant interaction effects for five of the nine outcome variables (P < 0.05, 3.6%-4.8% of explained variance). Participants with high stress who also had high CRF levels had lower SBP, DBP, LDL-C, TG, and total cardiometabolic risk than participants with high stress but low or moderate CRF levels. No significant main or interaction effects occurred for BMI, total cholesterol, high-density lipoprotein cholesterol, and glycated hemoglobin. Conclusion Better CRF is associated with more favorable levels of several cardiometabolic risk factors, specifically in participants experiencing high stress. Higher CRF may provide some protection against the health hazards of high chronic stress by attenuating the stress-related increase in cardiovascular risk factors.

    • Assessing long-term cortisol secretion presents difficulties when cortisol measurement is carried out by saliva, plasma and urine analyses. Hair cortisol has gained increased interest as an alternative biological marker. So far, one study has been published studying hair cortisol in endurance athletes, showing higher levels compared to controls. Using accelerometer data in the present study, we cross-sectionally explored the relationship between moderate physical activity (MPA) and vigorous physical activity (VPA) levels and hair cortisol concentrations after taking into account age, gender, and perceived stress. Hair specimens were collected from 46 university students (20 males, 26 females, M-age +/- SD = 21.2 +/- 1.87 years). Participants provided information about their socio-demographic background and levels of perceived stress. Accelerometer data were collected to assess physical activity. Cortisol concentrations were measured in the first 3-cm hair segment nearest to the scalp. MPA was not correlated with hair cortisol content (r = -0.08). A significant correlation was found between VPA and hair cortisol (r = 0.34, p < 0.05). A regression analysis revealed that participants with higher VPA had elevated hair cortisol concentrations even after taking into account age, gender and perceived stress (beta = 0.33, p < 0.05, Delta R-2 = 0.106). This is the first study showing that objectively assessed VPA is associated with increased hair cortisol levels in young adults. As VPA can be regarded as a physical stressor, it seems imperative that researchers consider participants' levels of VPA if they examine the relationship between stress exposure, hair cortisol and health.

  • Physical Activity in Employees with Differing Occupational Stress and Mental Health Profiles: A Latent Profile Analysis
  • 2014
  • Ingår i: Psychology of Sport And Exercise. - : Elsevier BV. - 1469-0292. ; 15:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: To examine whether employees with differing occupational stress and mental health profiles differ in their self-reported levels of physical activity. Design: Cross-sectional survey data. Method: The sample consisted of 2660 Swedish health care workers and social insurance officers (85% women, M = 46.3 years). Latent profile analysis was performed to identify classes. Between-class-differences in physical activity were tested via c2-tests and multinominal logistic regression analyses using sex, age, BMI, marital status, children at home, caregiving, and smoking as covariates. Results: Latent profile analysis resulted in a six-profile solution. Two pairs of classes had equal stress levels, one pair with high stress, one pair with moderate stress. Within each pair, one group showed some resilience (i.e. only moderate mental health problems despite high stress or good mental health despite moderate stress), whereas the other did not. The other two classes were characterized by either low stress and good mental health or moderate-tohigh stress and elevated mental health problems. Participants who were resilient to high or moderate stress were more active than participants of the corresponding non-resilient classes. Participants with low stress and good mental health reported the highest physical activity levels, participants with high stress and high mental health problems reported the lowest physical activity levels. Conclusions: The findings suggest that physical activity is associated with resilience to occupational stress, and that beyond primary prevention efforts to make work less stressful regular physical activity should be a target variable for health professionals working in the occupational setting.

    • Aims and objectives The purpose of this study was to examine, by using patient cohort data, the changes in exercise habits during a 12-month multimodal treatment period, in patients seeking specialist care for stress-related exhaustion. Background Randomised controlled trials have greatly contributed to the fact that both physicians and patients regard regular exercise participation as a highly valuable and effective treatment for mental health disorders. Nevertheless, little is known about the adherence to physical activity recommendations for patients with stress-related mental problems in a clinical setting. Knowledge about what can be achieved within the clinical context, and how current treatments can be improved, is crucial for clinicians, researchers, educators, managers and policy makers involved in nursing practice. Design Longitudinal analysis of patient cohort data. Methods The sample consisted of 169 patients (79% women; mean age = 42·7 years) who were referred to a stress clinic due to stress-related exhaustion. All patients received multimodal treatment with similar components. Two different approaches to promote exercise were used in the clinical work (general comprehensive instruction either with or without an 18-week coached exercise programme). The self-reported overall exercise level was assessed at baseline and at three, six and 12 months after the first visit. Group by time effects were examined with repeated measures analyses of variance. Results The frequency, duration and intensity of exercise increased substantially during the first three months of multimodal treatment. Although exercise levels tended to decrease thereafter, there was still a significant time effect at the 12-month follow-up showing that follow-up exercise levels were higher than at baseline. Conclusion Both general exercise instructions and coached exercise were effective in promoting exercise involvement. Relevance to clinical practice Exercise can be successfully promoted as a part of multimodal treatment in patients with stress-related exhaustion.

  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract Background Long-term sick leave due to mental health problems, especially among women, is a substantial problem in many countries, and a major reason for this is thought to be psychosocial stress. The recovery period of different patient groups with stress-related mental health problems can differ considerably. We have studied the course of mental health symptoms during 18 months of multimodal treatment in relation to sex and age in a group of patients with stress-related exhaustion. Methods The study group includes 232 patients (68% women) referred to a stress clinic and who fulfilled the criteria for Exhaustion Disorder (ED). The majority also fulfilled diagnostic criteria for depression and/or anxiety; this was similar among women and men. Symptoms were assessed at baseline, three, six, 12 and 18 months by the Shirom-Melamed Burnout Questionnaire (SMBQ) and the Hospital Anxiety and Depression scale (HAD). A total SMBQ mean score of ≥ 4 was used to indicate clinical burnout, which correlates well with the clinical diagnosis of ED. Results There were no statistically significant differences between women and men or between young and old patients in the self-reported symptoms at baseline. The proportion that had high burnout scores decreased over time, but one-third still had symptoms of clinical burnout after 18 months. Symptoms indicating probable depression or anxiety (present in 34% and 65% of the patients at baseline, respectively) declined more rapidly, in most cases within the first three months, and were present only in one out of 10 after 18 months. The course of illness was not related to sex or age. The duration of symptoms before seeking health care, but not the level of education or co-morbid depression, was a predictor of recovery from symptoms of burnout after 18 months. Conclusions The course of mental illness in patients seeking specialist care for stress-related exhaustion was not related to sex or age. The burden of mental symptoms is high and similar for men and women, and at the 18 month follow-up, one-third of the study group still showed symptoms of burnout. A long duration of symptoms before consultation was associated with a prolonged time of recovery, which underlines the importance of early detection of stress-related symptoms.

  • Long-term follow-up of residual symptoms in patients treated for stress-related exhaustion
  • 2020
  • Ingår i: BMC Psychology. - : Springer Science and Business Media LLC. - 2050-7283. ; 8:1
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: Many patients with stress-related exhaustion seem to struggle with long-term recovery. The primary aim of this study was to explore residual symptoms and perceived recovery in patients previously treated for stress-related exhaustion, 7 years after seeking care. METHODS: A total of 217 former patients (74% women) previously treated for exhaustion disorder were asked to participate in follow-ups 2, 3, 5, and 7years post treatment. Symptoms of depression, and anxiety were measured with questionnaires. Remaining symptoms of extreme fatigue, sleep disturbances, problems with concentration, problems with memory and reduced stress tolerance, were rated with single item questions. A subgroup of patients (n=163) participated in a clinical assessment to confirm residual stress-related exhaustion not caused by other diseases. RESULTS: Almost half of the patients previously treated for stress-related exhaustion perceive fatigue 7 years after initially seeking care, and as many as 73% reported decreased stress tolerance. The clinical assessment confirmed that a third of the patients were clinically judged as still suffering from stress-related exhaustion. Male and female patients showed similar patterns regarding residual symptoms. CONCLUSIONS: One third of patients with exhaustion disorder are clinically judged to have exhaustion, 7 years after seeking care. Further studies are needed to elucidate the reason for such a long-term recovery and ultimately to identify methods for prevention.

  • Prevalence and course of somatic symptoms in patients with stress-related exhaustion: does sex or age matter
  • 2014
  • Ingår i: BMC Psychiatry. - 1471-244X. ; 14:118
  • Tidskriftsartikel (refereegranskat)abstract
    • Abstract Background Both mental and somatic symptoms are commonly reported in patients with stress-related problems. We have explored the prevalence of somatic symptoms in patients seeking medical care for stress-related mental health problems and followed the course of illnes alongside with that the patients receive multimodal treatment. Method This study comprises data from 228 patients (69% women, mean age 43 years) who fulfilled the criteria for Exhaustion Disorder (ED). Somatic symptoms were assessed at baseline and after 3, 6, 12 and 18 months using the one-page questionnaire Primary Care Evaluation of Mental Disorders. Prevalence of different symptoms was compared between men and women and patients, over and below 40 years of age, and possible predictors of recovery were explored. Results Tiredness and low energy are the core symptom reported by the patients. Almost all (98%) reported at least one somatic symptom and 45% reported six symptoms or more, which was similar for men and women. Nausea, gas or indigestion are the most common symptoms (67%) followed by headaches (65%) and dizziness (57%). The number of symptoms reported was significantly related to the severity of mental health problems. The only difference between the sexes was that “chest pain” and “pain or problems during sexual intercourse” were more common among males. Patients over forty more often reported “pain in arms, legs or joints, knees, hips” and this was also the only symptom that did not significantly decline during treatment. Neither sex, age, symptom duration before seeking medical care, education or any other predictor tested was shown to predict recovery in patients reporting six symptoms or more. Conclusion A heavy burden of somatic symptoms was generally seen in most patients with stress-related exhaustion. Somatic symptoms are equally common in males and females and in younger and older patients. The somatic symptoms seem to be mostly stress-related since all symptoms, except musculoskeletal pain, reduce with individualised treatment designed for stress-related mental problems. This study brings to attention the complicated burden of both somatic and mental symptoms in patients with stress-related exhaustion, raising several clinical implications of interest to discuss.

    • OBJECTIVE: The aim of this study was to assess the construct and predictive validity of a new instrument for self-rating of stress-related Exhaustion Disorder (s-ED). METHODS: Public healthcare workers and social insurance officers, 85% females, were included (N = 2,683) in a longitudinal study. The s-ED instrument, based on clinical criteria for Exhaustion Disorder, was used at baseline to classify participants into three categories: non-s-ED, light/moderate s-ED and pronounced s-ED. Other assessments include burnout, anxiety, depression and work ability. Sick leave at follow-up after 2 years was defined as 14 days of ongoing sick leave (SA14) or a period of 60 days of sick leave during the last 12 months (SA60). Associations at baseline were expressed as prevalence ratios, and adjusted relative risks (RR) were calculated using Cox regression. RESULTS: At baseline, 16% reported s-ED. Scores of depression, anxiety and burnout and the rate of poor work ability increased with increasing severity of s-ED. Self-reported exhaustion at baseline increased the risk of reporting sickness absence at follow-up; pronounced s-ED RR 2.7; CI 1.8-4.0 for SA14 and RR 3.4; CI 2.3-5.2 for SA60. CONCLUSIONS: Self-rated ED corresponded well to established scales for mental health, indicating sufficient construct validity. Individuals reporting s-ED at baseline were more likely to report sickness absence at follow-up, confirming its predictive properties. The s-ED instrument may be a useful tool for occupational health services in identifying human service workers at risk of having or developing a potentially disabling stress-related mental illness.

    • The use of a four-level questionnaire to assess leisure time physical activity (PA) and its validation is reviewed in this paper. This questionnaire was first published in 1968 and has then been used by more than 600 000 subjects, especially in different population studies in the Nordic countries. A number of modifications to the questionnaire have been published. These are mostly minor changes, such as adding practical examples of activities to illustrate the levels of PA. Some authors have also added duration requirements that were not included for all levels of PA in the original version. The concurrent validity, with respect to aerobic capacity and movement analysis using objective measurements has been shown to be good, as has the predictive validity with respect to various risk factors for health conditions and for morbidity and mortality.

  • Is obsessive–compulsive personality disorder related to stress-related exhaustion?
  • 2021
  • Ingår i: Brain and Behavior. - : Wiley. - 2162-3279. ; 11:6
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Recovery from stress-related diagnoses can, in some cases, be long-lasting, and several different factors could be related to such a lengthy recovery. One plausible aspect is obsessive–compulsive personality disorder (OCPD), which has previously been seen to be related to stress-related mental health. Thus, the aim of this study was to investigate whether recovery from exhaustion disorder (ED) is associated with OCPD. Methods: This study includes data from 147 patients (78% women, mean age 52.4±9.8years) who have been treated for ED. Clinical assessment was performed 7–10years after first seeking care identifying patients with residual exhaustion. Symptoms of OCPD were concomitantly measured and several aspects of work- and private-related stress exposure. Results: The main result of this study is that patients with residual clinical ED report OCPD to a greater extent, compared with patients who no longer fulfill the clinical criteria for ED, 7–10years after seeking care. Patients with OCPD that have not recovered report “excessive devotion to work” to a higher degree than patients with OCPD that have recovered. Conclusion: The results indicate that factors related to OCPD may be of clinical importance for the patient's recovery from ED. However, prospective studies should be conducted and studies elucidating whether symptoms of exhaustion among patients with OCPD can be affected by therapeutic interventions. © 2021 The Authors.

    • Exhaustion disorder (ED) is a stress-related disorder that often implies a great burden on the individual patient as well as on society. Previous studies have shown that ED is associated with metabolic deviations, such as lowered fasting glucose. Several mechanisms have been discussed as a plausible explanation of the lack of energy described by these patients. Metabolic processes and reduced ability to mobilize energy have been suggested as important factors. This study investigated metabolomics in 20 patients diagnosed with ED and compared them with 21 healthy controls. Plasma metabolic profiles were examined in both fasting and nonfasting (postprandial) conditions. Blood plasma samples were analyzed for metabolite content using gas chromatography mass spectrometry. A total of 62 different metabolites were simultaneously detected in each of the samples. Multivariate models indicated systematic differences between patients with ED and healthy controls in both their fasting and nonfasting plasma metabolite levels. Lysine and octadecenoic acid were more abundant and glutamine, glycine, serine and gluconic acid were less abundant in the patients across both conditions. In the present study, we comprehensively and simultaneously screen for changes in a large number of metabolites. Our results show a difference in systemic metabolites between patients with exhaustion disorder and healthy controls both in the fasting and in the postprandial states. Here, we present new potential biomarkers mirroring exhaustion disorder metabolism.

  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Exhaustion Disorder (ED) is a stress-induced disorder, characterized by extreme fatigue, cognitive impairments, and intolerance to stress. These symptoms can be long-lasting, suggesting that the long-term stress may have initiated pathophysiological processes in the brains of patients with ED. The aims of the study were I) to investigate if plasma levels of neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and phos-phorylated tau (p-tau181) differ between patients with ED and healthy controls, and II) to investigate if these differences persist over time.Method: Plasma NfL, GFAP and p-tau181 were quantified in 150 patients with ED at the time of diagnosis (baseline), 149 patients at long-term follow-up (7-12 years later, median follow-up time 9 years and 5 months), and 100 healthy controls.Results: Plasma levels of NfL and GFAP were significantly higher in the ED group at baseline compared with controls (mean difference of NfL 0.167, 95 % CI 0.055-0.279; mean difference of GFAP 0.132, 95 % CI 0.008-0.257), while p-tau181 did not differ between the groups. Plasma levels of NfL were significantly lower in the ED group at follow-up than in the same group at baseline (mean difference-0.115, 95 % CI - 0.186- (-0.045)), while plasma levels of GFAP did not differ between the groups, and plasma levels of p-tau181 were significantly higher in the ED group at follow-up than in the same group at baseline (mean difference 0.083, 95 % CI 0.016-0.151). At follow-up, there were no significant differences between the ED group and the control group for any of the proteins.Conclusion: Plasma levels of NfL and GFAP were increased in patients with ED during the first months of the disease, indicative of axonal and glial pathophysiological processes, but had normalized at long-term follow-up.

    • Physical exercise is considered to be beneficial for cardiovascular health. Nevertheless, the underlying specific molecular mechanisms still remain unexplored. In this study, we aimed to investigate the effects of voluntary exercise on vascular mechanical properties and gene regulation patterns in spontaneously hypertensive rats. By using ultrasound biomicroscopy in an ex vivo perfusion chamber, we studied the distensibility of the thoracic aorta. Furthermore, exercise-induced gene regulation was studied in aortae, using microarray analysis and validated with real-time PCR. We found that distensibility was significantly improved in aortas from exercising compared with control rats (P < 0.0001). Exercising rats demonstrated a striking pattern of coordinated downregulation of genes belonging to the heat shock protein family. In conclusion, voluntary exercise leads to improved vessel wall distensibility and reduced gene expression of heat shock protein 60 and 70, which may indicate decreased oxidative stress in the aortic vascular wall.

  • Voluntary physical exercise and coronary flow velocity reserve: a transthoracic colour Doppler echocardiography study in spontaneously hypertensive rats
  • 2005

    • In the present study, we have developed and demonstrated a coronary artery imaging protocol in rats using transthoracic high-frequency CDE (colour Doppler echocardiography) to investigate the potential direct effects of exercise on CFVR (coronary flow velocity reserve). SHR (spontaneously hypertensive rats) performed voluntary exercise for 6 weeks. Rats were then submitted to ultrasonographic examination and CFVR measurements. The LAD (left anterior descending coronary artery) was visualized using transthoracic CDE in a modified parasternal long-axis view. Doppler measurement was made in mid-LAD during baseline and adenosine-induced hyperaemic condition. Gene and protein expression in cardiac tissue were studied using real-time PCR and immunohistochemistry. Adenosine infusion significantly (P<0.001, as determined by ANOVA) decreased HR, without affecting blood pressure in anaesthetized SHR. A significantly greater adenosine dose-dependent response was seen in exercised rats compared with controls (P=0.02, as determined by ANOVA). The baseline flow velocity in mid-LAD was 0.33+/-0.06 and 0.41+/-0.14 m/s in the exercised and control animals respectively (P value was not significant). The maximum adenosine-induced response was reached at a dose of 140 microg.kg-1 of body weight.min-1, and CFVR averaged at 2.6+/-0.53 and 1.5+/-0.24 in exercised and control animals respectively (P<0.01). Gene expression of CuZnSOD was up-regulated by 21% in exercised animals compared with controls (1.1+/-0.16 compared with 0.89+/-0.09; P<0.01), whereas eNOS expression was unchanged. In conclusion, CFVR in rats can be non-invasively assessed using CDE with high feasibility. Physical exercise is associated with improved CFVR and antioxidative capacity in SHR.

    • Forced training has been shown to have beneficial vascular effects in various animal exercise models. In the present study, we explored possible physiological and molecular effects of voluntary physical exercise on various vascular beds. SHR (spontaneously hypertensive rats) performed voluntary exercise for 5 weeks in a computerized wheel cage facility. Ex vivo myograph studies revealed an increased sensitivity of the ACh (acetylcholine)-mediated vasodilation in resistance arteries of the exercised animals (ED50=15.0+/-3.5 nmol/l) compared with the controls (ED50=37.0+/-8.8 nmol/l; P=0.05). The exercise/control difference was abolished after scavenging reactive oxygen radicals. In conduit arteries, ACh induced a similar vasodilatory response in both groups. The in vivo aortic wall stiffness, assessed by means of Doppler tissue echography, was significantly lower in the exercising animals than in controls. This was demonstrated by significantly increased peak systolic aortic wall velocity (P=0.03) and the velocity time integral (P=0.01) in exercising animals compared with controls. The relative gene expression of eNOS (endothelial nitric oxide synthase) was similar in both groups of animals, whereas Cu/ZnSOD (copper/zinc superoxide dismutase) gene expression was significantly increased (+111%; P=0.0007) in the exercising animal compared with controls. In conclusion, voluntary physical exercise differentially improves vascular function in various vascular beds. Increased vascular compliance and antioxidative capacity may contribute to the atheroprotective effects associated with physical exercise in conduit vessels.

  • A pre/post analysis of the impact of the COVID-19 pandemic on the psychosocial work environment and recovery among healthcare workers in a large university hospital in Sweden

  • Ingår i: Journal of Public Health Research. - : SAGE Publications. - 2279-9028 .- 2279-9036. ; 10:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The impact of the COVID-19 pandemic on workload, mental health, and well-being of healthcare workers, and particularly those on the front-line, has received considerable attention. Design and methods: We surveyed hospital employees about their working environment during the pandemic and identified departments which were negatively affected in comparison to the pre-pandemic situation, as well as factors contributing to this. Setting and participants We surveyed all hospital employees at Sahlgrenska University Hospital, Sweden in September 2020 and compared results across departments and to the results of a large employee survey from October 2019. Results: The overall impact of the pandemic on perceived working conditions and possibility for recovery differed among departments. During the pandemic, healthcare workers working with COVID-19 patients reported poorer working environments than other employees. Factors significantly related to perception of work environment and recovery during the pandemic included worries of being infected, departmental transfer, and having insufficient access to personal protective equipment. Men reported better working conditions than women in all, but one item and higher age was related to better perceived working environment. Conclusions: Our results indicate that the pandemic differentially affects hospital departments and underscores the multifactorial nature of this topic. Contributing factors to poor perceived working environment could be addressed at times of high workload, such as during the pandemic, including providing appropriate support to managers, ensuring possibility for recovery during working hours, and acknowledging worries about infection. Young healthcare workers and staff who are relocated due to the pandemic warrant special attention.

    • OBJECTIVE: This study analyzes longitudinal associations between self-reported leisure-time physical activity (PA) and perceived stress, burnout and symptoms of depression and anxiety. METHOD: Cohort data collected in 2004 and 2006 from health care and social insurance workers in western Sweden (2694 women; 420 men) were analyzed. Cox regression was conducted to examine associations between baseline levels of PA and mental health (MH) problems 2 years later. RESULTS: Cross-sectional analysis show that individuals reporting either light physical activity (LPA) or moderate-to-vigorous physical activity (MVPA) were less likely to report high levels of perceived stress, burnout and symptoms of depression and anxiety, as compared to individuals reporting a sedentary lifestyle. The risks of symptoms of depression, burnout, and high stress levels at follow-up were significantly lower for those reporting LPA or MVPA at baseline. For symptoms of anxiety, an activity level corresponding to MVPA was required. CONCLUSION: Participation in PA appeared to lower the risk of developing MH problems two years later. This relationship involved LPA and MVPA regarding feelings of depression, burnout and perceived stress, and exclusively MVPA regarding feelings of anxiety. The implications of these findings are important, as preventive strategies for psychosocial stress and mental health problems are needed.

    • The influence of acute mental stress and the effect of electrically induced skeletal muscle contractions on natural cytotoxicity in vivo was investigated in spontaneously hypertensive rats Natural cytotoxicity in vivo was measured as the clearance of injected 51Cr-labelled YAC-1 lymphoma cells from the lungs, which are specifically lysed by natural killer cells. The mental stress consisted of an air jet directed towards the animals in their cage for 25 min. During the mental stress there was a significant increase in natural cytotoxicity. Thus, retained radioactivity in the lungs was decreased to 74 +/- 6% of the control levels which was set to 100% (P < 0.01). This augmentation of YAC-1-cell clearance could be blocked with the beta-adrenergic receptor antagonist Timolol. Two hours after termination of the air stress, in vivo cytotoxicity had returned to control levels. In contrast, acute physical stress, consisting of electrically induced muscle contractions for 60 min, had no significant effects on in vivo cytotoxicity, either during the stimulation or 1, 2 or 24 h after the stimulation. Further, significantly increased plasma levels of adrenaline were seen after the air jet stress, but not after muscle stimulation. There were no significant changes in plasma noradrenaline levels either after air stress or muscle stimulation. These results indicate that changes in in vivo cytotoxicity after mild mental stress are dependent on increased plasma catecholamine levels while acute physical stress without changes in catecholamine levels, does not influence in vivo cytotoxicity.

  • Chronic intracerebroventricular administration of beta-endorphin augments natural killer cell cytotoxicity in rats.

  • Tidskriftsartikel (refereegranskat)abstract
    • We have studied the effect of chronic intracerebroventricular (i.c.v.) infusion of different opioid peptides on natural killer (NK) cell mediated cytotoxicity in vivo in the spontaneously hypertensive rat (SHR). The in vivo NK cell activity was measured as the clearance of 51Cr-labelled YAC-l lymphoma cells from the lung tissues. Further, the phenotype of lymphocytes in spleen and peripheral blood was analysed by flow cytometry (FACS). All opioid drugs were administered i.c.v. for 6 days with osmotic minipumps releasing 1.0 microliter/h. beta-Endorphin (10 or 20 micrograms/rat per day) significantly increased NK cell cytotoxicity in vivo. The opioid receptor antagonist naloxone (10 mg/kg, i.p.) given immediately before the injection of YAC-lymphoma cells, completely abolished the effects of i.c.v. administered beta-endorphin. Corresponding doses of beta-endorphin administered subcutaneously (s.c.) with minipumps for 6 days did not significantly affect NK cell cytotoxicity. Neither Leu- or Met-enkephalin (20 micrograms/rat per day) nor dynorphin (20 micrograms/rat per day) administered i.c.v. had any significant effects on NK cell activity. In beta-endorphin treated SHR, the percentage of cells with NK cell phenotype (OX52+/CD5-) in peripheral blood was not significantly different from that of controls, while the percentage of cells with T cell phenotype (CD5+/OX52-) was significantly decreased. The percentage of splenic NK cells (OX52+/CD5-) and T cells (CD5+/OX52-) was also unchanged by beta-endorphin treatment i.c.v. These results suggest that of the opioid peptides administered i.c.v., only beta-endorphin augments in vivo NK cell mediated cytotoxicity. We thus conclude that these effects most probably are centrally and opioid receptor mediated effects, since beta-endorphin in the same dose administered peripherally does not influence in vivo NK cell cytotoxicity.

  • Cognitive impairment in patients with stress-related exhaustion

    • Patients who seek medical care for stress-related mental health problems frequently report cognitive impairments as the most pronounced symptom. The purpose of the present study was to compare cognitive function in patients with stress-related exhaustion with that in healthy controls, using a comprehensive battery of cognitive tests. We also explored whether neuropsychological findings were related to severity of illness measured using the Shirom–Melamed burnout questionnaire and hospital anxiety and depression scale. Thirty-three patients (15 males) and 37 healthy controls (11 males), mean age 46 years [standard deviation (SD) 3.9] and 47 years (SD 4.3), respectively, were included in the final analysis. Five cognitive domains were assessed: (1) speed, attention and working memory, (2) learning and episodic memory, (3) executive functions, (4) visuospatial functions and (5) language. The most pronounced difference between patients and controls was seen on executive function, when tested with a multidimensional test, including aspects of speed, control and working memory. The patients also performed poorer on Digit span, measuring attention span and working memory as well as on learning and episodic memory, when measured as delayed recall and the difference between immediate and delayed recall. Delayed recall was the only test that was significantly related to severity of burnout symptoms among the patients. This could reflect poor cognitive sustainability in the patients with the highest burnout scores, as this particular test was the last one performed during the test session. This study clearly shows that cognitive impairment should be considered when evaluating and treating patients who seek medical care for stress-related exhaustion.

  • Duration and mechanisms of the increased natural cytotoxicity seen after chronic voluntary exercise in rats.

  • Tidskriftsartikel (refereegranskat)abstract
    • We have recently shown that in vivo natural cytotoxicity is enhanced after chronic exercise in spontaneously hypertensive rats (SHRs). In the present report, we have studied the duration of this augmentation and some possible mechanisms involved. Exercise consisted of voluntary running for 4-5 weeks, with the running distance ranging from 2.7-15.6 km day(-1) during the last week of running. In vivo cytotoxicity was measured as clearance of injected 51Cr-labelled YAC-1 lymphoma cells from the lungs. The in vivo natural cytotoxicity was increased in running SHRs, and also in SHRs that had their running wheel locked for 24 and 48 h prior to the experiment, and was still present after 96 h. The enhancement of in vivo cytotoxicity after 5 weeks of exercise was abolished after an acute injection of the beta-adrenergic receptor antagonist timolol (0.5 mg kg(-1) i.v.), indicating that catecholamines are involved in this augmentation. Interestingly, 24 h after the last exercise bout, the increased natural cytotoxicity could be blocked by timolol. The opioid receptor antagonist naloxone given subcutaneously for 7 days by osmotic pumps (6 mg kg(-1) h(-1)) could not reverse the increased in vivo cytotoxicity seen in the running SHRs, suggesting that opioid receptor mechanisms are not involved, or at least not the naloxone-sensitive mu-receptor. Natural immunity was not influenced by the histamine H2 receptor antagonist ranitidine, either in controls or in runners, indicating that the natural killer cell-regulatory effect of histamine is not present in SHRs and does not seem to be involved in the exercise-induced changes in natural immune function. We conclude that the augmentation of in vivo natural cytotoxicity after voluntary chronic exercise in rats is long-lasting and that the augmentation is partly mediated by beta-adrenergic receptors.

    • Burnout has several different definitions, and attempts have been made to discriminate between burnout as a psychological construct and burnout as a clinical entity. A large body of research has focused on elucidating the biological link between stress exposure and burnout and/or finding a clinically usable biomarker for burnout. The objective of this narrative review is to summarize the main end ocrine and immune findings in relation to burnout. The literature has primarily focused on dysregulation of the hypothalamus-pituitary-adrenal (HPA) axis. However, albeit the large body of studies, it cannot be concluded that clear effects are seen on HPA axis function in people with burnout. The HPA axis and anabolic acute reactivity to stress might be affected in clinical burnout. Plausible, effects of chronic stress might rather be seen when measuring responses to acute stress rather than resting state hormonal levels. Studies on other hormones, including thyroid hormones, prolactin and growth hormone in burnout subjects are inconclusive. It is important to note that this field is faced with many methodological challenges, one being the diurnal and pulsatile nature of many of the hormones of interest, including cortisol, which is not always considered. Another challenge is the heterogeneity regarding definitions and measurements of stress and burnout. Existing studies on burnout and immune function are heterogeneous regarding the results and no firm conclusion can be made if clinically relevant immune changes are present in burnout subjects. An overall conclusion is that existing research cannot confirm any homogenous reliable endocrinological or immunological changes related to burnout.

    • Chronic voluntary exercise in wheels for 5 weeks in spontaneously hypertensive rats (SHR) augments in vivo natural killer (NK) cell cytotoxicity. Endogenous beta-endorphin is increased in cerebrospinal fluid after voluntary exercise in rats and we have recently shown that beta-endorphin administered i.c.v. augments NK cell mediated cytotoxicity in vivo in a similar way as chronic voluntary exercise. We have now further investigated the involvement of central opioid systems in the exercise-induced augmentation in natural immunity. Exercise consisted of voluntary running in wheels for 5 weeks. In vivo cytotoxicity was measured as clearance of injected 51Cr-labeled YAC-1 lymphoma cells from the lungs. The clearance of YAC-1 cells in vivo was significantly increased in runners as compared to sedentary controls. Selective delta, kappa, or mu-opioid receptor antagonists were administered i.c.v. with osmotic minipumps during the last 6 days of the 5 weeks of running. The delta-receptor antagonist naltrindole (40-50 microg/day) significantly but not completely inhibited the enhanced NK-cell cytotoxicity seen after 5 weeks of exercise. Neither the kappa-receptor antagonist nor-BNI or the mu-receptor antagonist beta-FNA influenced the augmentation in NK cell cytotoxicity. Nor-BNI per se significantly augments in vivo cytotoxicity, indicating some inhibiting effect on natural immunity that could be mediated through the kappa-opioid receptor. Our data suggest the involvement of central delta-opioid receptors in the enhancement of natural cytotoxicity seen after chronic voluntary exercise.

  • Forskningsöversikt (refereegranskat)abstract
    • Natural immunity, including that of the natural killer (NK) cells, is strongly influenced by physical exercise, but the physiological significance of the reported changes in NK cells after exercise training is as yet unclear. The exercise effect is likely mediated by interactions between the central nervous and endocrine systems. Chronic activation of endogenous opioid systems augments natural cytotoxicity. We have investigated the possible involvement of opioids in the exercise-induced enhancement of NK cell function. The pathways by which the central nervous system may communicate with the periphery include neuroendocrine outflow via the hypothalamic-pituitary-adrenal axis and the autonomic nervous system (ANS) through direct nerve fiber connections with cells or the organs of the immune system. This review will discuss the role of various neuroendocrine factors such as growth hormone, catecholamines and glucocorticoids and the role of the ANS, in particular the sympathetic division, in modulating NK cell function in response to exercise.
