Lehmann H, Otte N, Kraus T, Esser A, Krabbe J. Evaluation and Comparison of Relaxation-Related Workplace Interventions Among Office Workers at an Insurance Institution: An Intervention Study. INQUIRY : A JOURNAL OF MEDICAL CARE ORGANIZATION, PROVISION AND FINANCING 2024; 61:469580241242793. [PMID: 38591360 PMCID: PMC11005502 DOI: 10.1177/00469580241242793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 03/08/2024] [Accepted: 03/11/2024] [Indexed: 04/10/2024]
Abstract
Relaxation-related workplace interventions can be counterstrategies for stress due to office work and should be evaluated for success after implementation. This study reports on the evaluation and comparison of 3 relaxation techniques introduced as an intervention for health promotion. A Germany-wide multicenter evaluation of a 3-month relaxation intervention (30 min, once a week) including autogenic training, progressive muscle relaxation (PMR) or Tai Chi was conducted at 14 locations as an intervention study. Anonymous questionnaires (n = 244) were used to collect self-reports of perceived stress after the courses. Status before the courses (pre) and after completion (post) were reported at the end of the intervention. All 3 relaxation techniques were able to improve the subjective perception of stress (SPS) score. Autogenic training was reported to improve all singular items with large effects, whereas only 2 items showed change for Tai Chi and none for PMR. Singular items were also influenced by the location of the courses. All 3 methods were able to improve stress-related outcomes in terms of stress perception and individual aspects of stress management. For this specific intervention autogenic training yielded the largest and wide-ranging effects. Tai Chi was also effective, but additional effect due to an associated increase in physical activity were not found. For a workplace intervention PMR could not be recommended based on this study. The literature on workplace interventions is surprisingly scarce, and future studies should focus on the selection of appropriate participants while avoiding potential bias.

Mar K, Rivers JK. The Mind Body Connection in Dermatologic Conditions: A Literature Review. J Cutan Med Surg 2023; 27:628-640. [PMID: 37898903 PMCID: PMC10714694 DOI: 10.1177/12034754231204295] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 04/14/2023] [Accepted: 09/04/2023] [Indexed: 10/31/2023]
Abstract
Psychodermatology pertains to the relationship between the skin and brain. This review aims to summarize the evidence of the mind body connection in four psychophysiological conditions: rosacea, atopic dermatitis (AD), acne vulgaris (AV), and psoriasis. A literature search was conducted using several English language databases. All four conditions share similar psychiatric co-morbidities, including but not limited to anxiety, depression, and suicidality. In rosacea, the upregulation of transient receptor potential vanilloid type 1, Toll like receptor 2, and Th17 cells releases downstream products that are simultaneously implicated in mood disorders. Stress exacerbates AV through the hypothalamic-pituitary-adrenal (HPA) system, which alters functioning of sebocytes and Cutibacterium acnes. In AD and psoriasis, the HPA axis influences Th1, Th2, Th22, and Th1, Th17 immune mediated responses, respectively. This leads to the secretion of pro-inflammatory cytokines which are also involved in the pathogenesis of anxiety and depression. Neurotransmitters implicated in mental illness, such as gamma-aminobutyric acid and serotonin, may also play a role in the development of AD and psoriasis. The management of cutaneous disease may mitigate psychological distress, and future research may show the corollary to also be true.

Schricker IF, Nayman S, Reinhard I, Kuehner C. Trait and state effects of different modes of thinking on salivary cortisol in daily life in patients with recurrent major depression and healthy individuals. Psychoneuroendocrinology 2023; 155:106307. [PMID: 37290378 DOI: 10.1016/j.psyneuen.2023.106307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 05/23/2023] [Accepted: 05/23/2023] [Indexed: 06/10/2023]
Abstract
Habitual modes of thinking such as repetitive negative thinking (RNT), but also momentary cognitive processes such as mindwandering could be vulnerability factors for the course of Major Depressive Disorder (MDD). On the physiological level, cortisol represents an important biological stress marker of the hypothalamic-pituitary-adrenal (HPA) axis. Being a dynamic and non-invasive measure, salivary cortisol can be assessed in daily life via Ambulatory Assessment (AA). So far, consensus exists on a dysregulation of the HPA axis in MDD. However, findings are ambiguous and AA-studies examining both trait and state level effects of cognitive processes on cortisol release in daily life in patients with recurrent major depression (rMDD) and healthy controls (HCs) are lacking. A sample of 119 (nrMDD=57, nHCs=62) participants underwent a baseline session, including self-rated questionnaires (RNT, mindfulness) followed by a 5-day AA, where participants indicated the occurrence of mindwandering and levels of mentalshift problems ten times per day via smartphone, and collected saliva cortisol samples five times per day. Via multilevel models, we found habitual RNT, but not mindfulness, to predict higher cortisol levels, with the effects being stronger in rMDD patients. State mindwandering and mentalshift problems predicted increased cortisol 20 min later across groups. State cognitions did not mediate the effects of habitual RNT on cortisol release. Our results suggest independent mechanisms of action for trait and state cognitions on cortisol activity in daily life and indicate a greater physiological vulnerability toward trait RNT and the tendency to experience mentalshift problems in patients with recurrent major depression.

Reciprocal Prospective Effects of Momentary Cognitions and Affect in Daily Life and Mood Reactivity Toward Daily Events in Remitted Recurrent Depression. Behav Ther 2023; 54:274-289.

Abstract
Major depressive disorder is a recurrent condition. Potential risk factors for future episodes are maladaptive cognitions, such as rumination and unfavorable reactivity toward negative daily events. Positive thoughts and positive daily events, in contrast, could act as a buffer against mood deterioration. The aim of the present study is to (a) examine differences in daily affect and cognitions in remitted depressed patients with a history of recurrent episodes (rMDD) and healthy controls, (b) analyze reciprocal prospective effects of momentary cognitions and affect, and (c) investigate effects of daily events on affect and cognitions in both groups. A sample of N = 102 participants underwent an ecological momentary assessment (EMA) phase of 5 consecutive days, where rMDD patients (n = 51) and healthy controls (n = 51) indicated their momentary rumination, positive thoughts, affect, and the occurrence of daily events 10 times per day. Via multilevel lag models, we found higher rumination to predict a decrease of positive affect (PA) in the rMDD group, but no effect of rumination on subsequent negative affect (NA) in either group. Higher positive thoughts predicted an increase in PA and a decrease in NA, similarly strong in both groups. Regarding daily events, rMDD patients reported a stronger increase in NA and rumination following negative daily events compared to controls, whereas an observed subsequent decrease of PA and positive thoughts was not moderated by group. Following positive daily events, rMDD patients showed a stronger increase in PA and positive thoughts and a stronger decrease in NA and rumination than controls. For interventions targeting relapse prevention, our results indicate the implementation of strategies fostering the responsiveness to positive events and the up-regulation of positive affect.

Abstract
Recent extensive evidence suggests that ambient fine particulate matter (PM2.5, with an aerodynamic diameter ≤2.5 μm) may be neurotoxic to the brain and cause central nervous system damage, contributing to neurodevelopmental disorders, such as autism spectrum disorders, neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease, and mental disorders, such as schizophrenia, depression, and bipolar disorder. PM2.5 can enter the brain via various pathways, including the blood-brain barrier, olfactory system, and gut-brain axis, leading to adverse effects on the CNS. Studies in humans and animals have revealed that PM2.5-mediated mechanisms, including neuroinflammation, oxidative stress, systemic inflammation, and gut flora dysbiosis, play a crucial role in CNS damage. Additionally, PM2.5 exposure can induce epigenetic alterations, such as hypomethylation of DNA, which may contribute to the pathogenesis of some CNS damage. Through literature analysis, we suggest that promising therapeutic targets for alleviating PM2.5-induced neurological damage include inhibiting microglia overactivation, regulating gut microbiota with antibiotics, and targeting signaling pathways, such as PKA/CREB/BDNF and WNT/β-catenin. Additionally, several studies have observed an association between PM2.5 exposure and epigenetic changes in neuropsychiatric disorders. This review summarizes and discusses the association between PM2.5 exposure and CNS damage, including the possible mechanisms by which PM2.5 causes neurotoxicity.

Effects of mindfulness-based stress reduction on psychological distress in health workers: A three-arm parallel randomized controlled trial. J Psychiatr Res 2022; 145:284-293. [PMID: 33199052 DOI: 10.1016/j.jpsychires.2020.11.011] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 11/02/2020] [Accepted: 11/04/2020] [Indexed: 12/30/2022]
Abstract
Mindfulness-based Stress Reduction (MBSR) has shown good efficacy for improving wellbeing in employees experiencing occupational stress. However, comparisons with other interventions, longer-term follow-up, and data from varying sociocultural contexts are lacking. This three-arm, parallel randomised controlled trial (RCT) examined the effects of MBSR on psychological distress in non-physician health workers in direct contact with patients. 105 participants were randomly allocated to either: (1) MBSR (N = 35), (2) Stress Management Course (SMC; N = 34) or (3) wait-list (N = 36). Participants and those assessing outcomes were blinded to group assignment. Participants completed questionnaires pre- and post-intervention and four months after the intervention. Psychological distress was measured using the General Health Questionnaire (GHQ-12) and Outcome Questionnaire (OQ-45). Secondary outcomes included perceived stress, job satisfaction, mindfulness skills and changes in salivary cortisol. 77 participants completed measures post-intervention and 52 at 4-month follow-up. MBSR showed a post-intervention effect in reducing GHQ-12 (ß = -0.80 [SE = 1.58] p < 0.01) and OQ-45 (ß = -0.72, [SE = 5.87] p < 0.05) psychological distress, compared to SMC and in reducing GHQ-12 (ß = -1.30 [SE = 1.38] p < 0.001) and OQ-45 (ß = -0.71, [SE = 5.58] p < 0.01) psychological distress compared to wait-list condition. In our secondary outcome, only MBSR was associated with a decrease in the cortisol awaking response by 23% (p < 0.05). At follow-up, only effects of MBSR on the psychological distress 'social role' subscale (ß = -0.76 [SE = 1.31] p < 0.05) remained significant, compared to SMC. In conclusion, MBSR appears useful in reducing short-term psychological distress in healthcare workers, but these effects were not maintained at follow-up. Trial registration: ISRCTN12039804.

Abstract
The COVID-19 pandemic continues to strongly affect people with health disadvantages, creating a heavy burden on medical systems and societies worldwide. Research is growing rapidly and recently revealed that stress-related factors such as socio-economic status, may also play a pivotal role. However, stress research investigating the underlying psychoneuroimmune interactions is missing. Here we address the question whether stress-associated neuroendocrine-immune mechanisms can possibly contribute to an increase in SARS-CoV-2 infections and influence the course of COVID-19 disease. Additionally, we discuss that not all forms of stress (e.g. acute versus chronic) are detrimental and that some types of stress could attenuate infection-risk and -progression. The overall aim of this review is to motivate future research efforts to clarify whether psychosocial interventions have the potential to optimize neuroendocrine-immune responses against respiratory viral infections during and beyond the COVID-19 pandemic. The current state of research on different types of stress is summarized in a comprehensive narrative review to promote a psychoneuroimmune understanding of how stress and its mediators cortisol, (nor)adrenaline, neuropeptides and neurotrophins can shape the immune defense against viral diseases. Based on this understanding, we describe how people with high psychosocial stress can be identified, which behaviors and psychosocial interventions may contribute to optimal stress management, and how psychoneuroimmune knowledge can be used to improve adequate care for COVID-19 and other patients with viral infections.
