Given the relationship between acute stress responses and health, finding strategies to deal with the unpleasant symptoms brought on by stress is essential. Massage therapy is a popular stress-reduction technique, but its effectiveness has yet to be shown. In that matter, this study investigates the effects of a 17-minute session of seated Amma massage on young healthy people. Subjective stress perception, anxiety and self-confidence were assessed before and after the massage using the Spielberger State Anxiety Scale (STAI-Y, Spielberger et al., 1983) and the Competitive State Anxiety Inventory (EEAC, Cury et al., 1999), together with cardiovascular parameters.

Indeed, poor working conditions and staff shortages have contributed to structural collapse and placed a heavy toll on healthcare workers’ (HCWs) well-being, with many suffering from stress, exhaustion, demoralization, and burnout. An additional factor driving qualified HCWs away is the repeated experience of moral distress, or the inability to act according to internally held moral values and perceived ethical obligations due to internal and external constraints. Despite general awareness of this crisis, we currently lack an organized understanding of how stress leads to poor health, wellbeing, and performance in healthcare workers. To address this critical issue, we first review the literature on moral distress, stress, and health in HCWs. Second, we summarize the biobehavioral pathways linking occupational and interpersonal stressors to health in this population, focusing on neuroendocrine, immune, genetic, and epigenetic processes. Third, we propose a novel Psychoneuroimmunological Model of Moral Distress and Health in HCWs based on this literature. Finally, we discuss evidence-based individual- and system-level interventions for preventing stress and promoting resilience at work. Throughout this review, we underscore that stress levels in HCWs are a major public health concern, and that a combination of system-level and individual-level interventions are necessary to address preventable health care harm and foster resilience in this population, including new health policies, mental health initiatives, and additional translational research.</p></div>","PeriodicalId":72656,"journal":{"name":"Comprehensive psychoneuroendocrinology","volume":"17 ","pages":"Article 100226"},"PeriodicalIF":0.0,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266649762400002X/pdfft?md5=795a99cf2b7843eaaa54083cbe498fbd&pid=1-s2.0-S266649762400002X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139699467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this exploratory study, we measured oxytocin (OT) and secretory immunoglobulin-A (s-IgA), the most abundant antibody in breast milk, and evaluated their associations with the same biomarkers in infant saliva and, consequently, with infant social engagement behavior. Fifty-five mother-infant dyads were home-visit and OT and s-IgA were assessed from breast milk and from infant saliva before and after a free-play interaction. Infant social behavior was coded offline using the Coding Interactive Behavior (CIB) and maternal anxiety self-reported. A path model revealed that mother's breast milk s-IgA impacted child social engagement via its links with child OT. In parallel, maternal breast milk OT was linked with infant social behavior through its association with the infant's immunity. This path was moderated by maternal anxiety; only in cases of high anxiety breast milk OT was positively connected to infant s-IgA. Our study, the first to measure OT and s-IgA in both breast milk and infant saliva in relation to observed social behavior, underscores the need for much further research on the dynamic interplay between breast milk composition, infant biomarkers, maternal mental health, and infant social outcomes. Results may suggest that biological systems in breast milk integrate to prepare infants to function in their social ecology through bio-behavioral feedback loops that signal the degree of stress in the environment.</p></div>","PeriodicalId":72656,"journal":{"name":"Comprehensive psychoneuroendocrinology","volume":"17 ","pages":"Article 100219"},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S266649762300053X/pdfft?md5=4fb158456df9468c46085f3cf4e072a0&pid=1-s2.0-S266649762300053X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139014272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forced migration involves a multitude of ongoing stressful and traumatic experiences, often resulting in lasting psychological symptoms for people resettling as refugees. Despite these risks, the underrepresentation of refugee populations in research—particularly in biological sciences—has impeded the allocation of effective resources and the development of novel interventions for these groups. This paper identifies and addresses key methodological challenges to successfully and appropriately conducting research with refugee and internally displaced communities, many of which have served as barriers to improving research representation for these populations. Methodological challenges discussed include language and literacy barriers; political fears; differing cultural dynamics between participants and researchers; and others. We provide practical recommendations for overcoming each challenge, often sourced from our experience conducting multi-year studies and interventions in refugee mental health. Several key strategies include the recruitment of researchers and research assistants from similar cultural and linguistic backgrounds as participants; providing detailed, ongoing communication about informed consent; avoiding assumptions regarding participants' understanding of concepts that may vary based on culture or experience (e.g., “voluntary” research; confidentiality); and adopting flexible data collection procedures compatible with participants’ needs and restrictions. Finally, we discuss the role of the researcher in regard to cultural competencies and partnering with the refugee community. Given the increasing global population of refugees, the strategies discussed in this paper are suggested in order to encourage future research in this underrepresented population and empower investigators to logistically carry out studies with refugees.</p></div>","PeriodicalId":72656,"journal":{"name":"Comprehensive psychoneuroendocrinology","volume":"16 ","pages":"Article 100217"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666497623000516/pdfft?md5=b2d8827b246878973e421e0829483d55&pid=1-s2.0-S2666497623000516-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135510207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
