Mental and physical health effects of meaningful work and rewarding family responsibilities.
Dich, N, Lund, R, Hansen, ÅM, Rod, NH
PloS one. 2019;(4):e0214916
Abstract
Positive feelings about work and family responsibilities benefit psychological well-being, but their physical health effects remain unexplored. The study assessed whether meaningful work and reward from taking care of family benefitted physical health to the same degree as mental health. Participants were 181 Danes aged 49-51. Participants reported on working conditions, providing care to family, depressive symptoms, and perceived stress. Physical health was operationalized as a physiological dysregulation (e.g., hypertension, high levels of blood sugar and cholesterol, high body mass index). A multidimensional index of physiological dysregulation was created using parameters of cardiovascular, metabolic, and immune function. As expected, meaningful work and sense of reward from taking care of family members were associated with better mental health. However, in women, the very same factors were positively associated with higher physiological dysregulation. We conclude that work and family factors promoting psychological well-being may have physical health trade-offs, particularly in women.

Abstract
This article examines how individual differences in adult attachment shape regulatory strategies and relationship behaviors, which in turn influence health-related responses, behaviors, and outcomes. We review links between attachment and physiological responses to stress (e.g., hypothalamic-pituitary-adrenal axis responses, cardiovascular responses, immune responses), health behavior (e.g., substance use, diet), and downstream health and disease outcomes. Recent evidence suggests that attachment insecurity (attachment anxiety and/or attachment avoidance) is associated with dysregulated physiological responses to stress, risky health behaviors, susceptibility to physical illness, and poorer disease outcomes. These associations depend, in part, on the relationship context, including the other partner's attachment style and behavior. We suggest that a dyadic approach considering both partners' attachment styles and behaviors will enhance interventions to promote health.

La Clinica terapeutica. 2017;(1):e42-e47
Abstract
Work-related stress may exert a negative impact on a variety of physical and psychological attributes relating to the health of employees and work organizations. Several studies conducted in Italy have shown that workers and employees who express less satisfaction show increased symptoms of obesity and cognitive disability. The latest evidence underlines the pathogenic relationship between stress and neurological disease through inflammatory neuro- immune activation. The aim of this review was to describe the relationship between workplace stress and adverse changes in lifestyle that develop into obesity, neuroinflammation and cognitive dysfunction. The molecular mechanisms involved and guidelines for the prevention of these trends are discussed briefly.

Abstract
BACKGROUND Chronic psychological stress is a risk factor for cardiovascular disease and mortality. Circulating hematopoietic progenitor cells (CPCs) maintain vascular homeostasis, correlate with preclinical atherosclerosis, and prospectively predict cardiovascular events. We hypothesize that (1) chronic caregiving stress is related to reduced CPC number, and (2) this may be explained in part by negative interactions within the family. METHODS We investigated levels of stress and CPCs in 68 healthy mothers - 31 of these had children with an autism spectrum disorder (M-ASD) and 37 had neurotypical children (M-NT). Participants provided fasting blood samples, and CD45+CD34+KDR+ and CD45+CD133+KDR+ CPCs were assayed by flow cytometry. We averaged the blom-transformed scores of both CPCs to create one index. Participants completed the perceived stress scale (PSS), the inventory for depressive symptoms (IDS), and reported on daily interactions with their children and partners, averaged over 7 nights. RESULTS M-ASD exhibited lower CPCs than M-NT (Cohen's d=0.83; p⩽0.01), controlling for age, BMI, and physical activity. Across the whole sample, positive interactions were related to higher CPCs, and negative interactions to lower CPCs (allp's<0.05). The adverse effects of group on CPCs were significantly mediated through negative interactions with the child (indirect β=-0.24, p⩽0.01). In the full model, greater age (β=-0.19, p=0.04), BMI (β=-0.18, p=0.04), and negative interactions with the child (β=-0.33, p<0.01) were independently associated with lower CPCs. M-ASD had a less healthy lipid profile (total cholesterol/HDL), which in turn, was associated with lower CPCs. CONCLUSIONS Chronic stress adversely impacts CPC number, an early-stage biomarker that predicts subclinical atherosclerosis and future CVD events, independent of traditional cardiovascular risk factors and inflammatory factors. Among maternal caregivers, child-related interpersonal stress appears to be a key psychological predictor of stress-related CVD risk.

Personality traits and emotional patterns in irritable bowel syndrome.
Muscatello, MR, Bruno, A, Mento, C, Pandolfo, G, Zoccali, RA
World journal of gastroenterology. 2016;(28):6402-15
Abstract
The review focuses on those personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness), constructs (alexithymia and distressed - Type D personality) and emotional patterns (negative and positive) that are of particular concern in health psychology, with the aim to highlight their potential role on the pathogenesis, onset, symptom clusters, clinical course, and outcome of irritable bowel syndrome (IBS). Personality traits and emotional patterns play key roles in affecting autonomic, immune, inflammatory, and endocrine functions, thus contributing not only to IBS clinical expression and symptomatic burden, but also to disease physiopathology. In this sense, psychological treatments should address those personality traits and emotional features that are constitutive of, and integral to IBS. The biopsychosocial model of illness applied to IBS acknowledges the interaction between biological, psychological, environmental, and social factors in relation to pain and functional disability. A holistic approach to IBS should take into account the heterogeneous nature of the disorder, and differentiate treatments for different types of IBS, also considering the marked individual differences in prevalent personality traits and emotional patterns. Beyond medications, and lifestyle/dietary interventions, psychological and educational treatments may provide the optimal chance of addressing clinical symptoms, comorbid conditions, and quality of life in IBS patients.

Abstract
Stress-related immune alterations can be consequential for health; they can enhance susceptibility to infectious agents and influence the severity of infectious disease, diminish the strength of immune responses to vaccines, reactivate latent viruses, and slow wound healing. Furthermore, stressful events and negative emotions promote systemic proinflammatory cytokine production while reducing beneficial local production of proinflammatory cytokines at the wound site that are important for wound healing. Dietary omega-3 and omega-6 polyunsaturated fatty acids (PUFAs) also influence systemic inflammation; high proportions of omega-6 to omega-3 boost inflammation, while omega-3 has anti-inflammatory properties. Additionally, the limited evidence thus far suggests that omega-3 PUFA may enhance local inflammatory responses at wound sites. Moreover, an individual's dietary proportion of omega-3 to omega-6 may influence the magnitude of inflammatory responses to stressful events. Thus, wound healing and surgery provide exemplars of how stress and depression can interact with the diet to influence important clinical outcomes.

Abstract
An extensive body of experimental and clinical evidence documents the negative impact of chronic psychological stress and depression on the immune system and health. Chronic stress and depression can result in general dysregulation of the immune system, of both cellular and humoral pathways, which may contribute to pathogenic infection and concomitant periodontal tissue destruction. In general, the evidence is consistent with the hypothesis that stress can modify the host defense and progression of periodontal infections in patients susceptible to periodontitis. However, substantial evidence also indicates that these conditions can mediate risk for disease, including periodontitis, through changes in health-related behaviors, such as oral hygiene, smoking and diet. The unequivocal interpretation of studies has also been hampered, in part, by issues related to conceptualization of stress and depression, as well as commonly associated comorbidities, such as diabetes, that can modify the onset and progression of periodontal disease. In addition, stress and depression appear to fall into a spectrum, ranging from mild to severe, involving a complex interaction of genetic background, coping strategies and environment. Differences in the conceptualization of stress and depression are probably important in assessing associations with other biologic and clinical measures. Future studies are necessary to clarify the complex interactions of chronic stress and depression in periodontal diseases.

Canadian journal of gastroenterology = Journal canadien de gastroenterologie. 2013;(3):e18-24
Abstract
Inflammatory bowel diseases (IBD), which consists of Crohn disease and ulcerative colitis, are chronic inflammatory conditions of the gastrointestinal tract. In genetically susceptible individuals, the interaction between environmental factors and normal intestinal commensal flora is believed to lead to an inappropriate immune response that results in chronic inflammation. The incidence of IBD have increased in the past century in developed and developing countries. The purpose of the present review is to summarize the current knowledge of the association between environmental risk factors and IBD. A number of environmental risk factors were investigated including smoking, hygiene, microorganisms, oral contraceptives, antibiotics, diet, breastfeeding, geographical factors, pollution and stress. Inconsistent findings among the studies highlight the complex pathogenesis of IBD. Additional studies are necessary to identify and elucidate the role of environmental factors in IBD etiology.

Abstract
BACKGROUND Acute psychological stress induced by academic exams is associated with dysregulated gastrointestinal and immune function. OBJECTIVE We examined whether supplementation with galactooligosaccharides reduced gastrointestinal dysfunction and the percentage of days with cold or flu in academically stressed undergraduate students. DESIGN In a randomized, double-blind study, subjects (n = 427) received 0, 2.5, or 5.0 g galactooligosaccharides for 8 wk around the time of fall final exams. Levels of stress and cold or flu symptom intensity (SI; 0 = not experiencing to 3 = severe) were recorded daily. The SI from 9 cold or flu symptoms was summed with 1 d of cold or flu defined as a sum >6. The Gastrointestinal Symptom Response Scale was completed weekly. RESULTS Stress was positively related to diarrhea, indigestion, and reflux syndromes and with abdominal pain, average daily cold or flu SI score, and the percentage of days with cold or flu. Gastrointestinal symptom scores for diarrhea (P = 0.0298), constipation (P = 0.0342), abdominal pain (P = 0.0058), and indigestion (P = 0.0003) syndromes were lower after galactooligosaccharide supplementation. The cold or flu SI score was affected by galactooligosaccharides and stress (P < 0.0001); 2.5 g was associated with a lower SI score across all levels of stress, but 5.0 g was protective only at lower levels of stress. The percentage of days with cold or flu was associated with galactooligosaccharides within different body mass index categories (P = 0.0002), wherein a 40% reduction in the percentage of days with cold or flu was observed in normal-weight individuals with 5.0 g galactooligosaccharides. This effect was not observed in overweight or obese individuals. CONCLUSIONS Acute psychological stress was directly related to symptoms of gastrointestinal dysfunction and cold or flu. Galactooligosaccharide supplementation reduced these symptoms and the number of days with cold or flu. This trial was registered at clinicaltrials.gov as NCT01137760.

Abstract
Our group has shown in a randomized clinical trial that psychological intervention to reduce stress in patients with stages II and III breast cancer led to enhanced immune function, fewer recurrences and improved overall survival. We hypothesized that patients with high levels of stress would have alterations in myeloid-derived suppressor cells (MDSC) compared to patients with lower stress. PBMC from 16 patients with high stress (n = 8) or with low stress (n = 8) after surgery as measured by the Impact of Event Scale (IES) questionnaire were evaluated for the presence of MDSC. Patients with higher IES scores had significantly elevated salivary cortisol levels (P = 0.013; 13 μg/dl vs. 9.74 μg/dl). Levels of IL-1Rα were also significantly elevated in the higher IES group (45.09 pg/ml vs. 97.16 pg/ml; P = 0.010). IP 10, G-CSF, and IL-6 were all higher in the high stress group although not to a significant degree. Flow cytometric analysis for CD33+/HLA-DR-neg/CD15+/CD11b+ MDSC revealed increased MDSC in patients with lower IES scores (P = 0.009). CD11b+/CD15+ cells constituted 9.4% of the CD33+/HLA DR-neg cell population in patients with high IES, vs. 27.3% in patients with low IES scores. Additional analyzes of the number of stressful events that affected the patients in addition to their cancer diagnosis revealed that this type of stress measure correlated with elevated levels of MDSC (P = 0.064). These data indicate the existence of a complex relationship between stress and immune function in breast cancer patients.
