Abstract
Background: Inflammatory bowel diseases (IBDs) have seen an exponential increase in incidence, particularly among pediatric patients. Psychological stress is a significant risk factor influencing the disease course. This review assesses the interaction between stress and disease progression, focusing on articles that quantified inflammatory markers in IBD patients exposed to varying degrees of psychological stress. Methods: A systematic narrative literature review was conducted, focusing on the interaction between IBD and stress among adult and pediatric patients, as well as animal subjects. The research involved searching PubMed, Scopus, Medline, and Cochrane Library databases from 2000 to December 2023. Results: The interplay between the intestinal immunity response, the nervous system, and psychological disorders, known as the gut-brain axis, plays a major role in IBD pathophysiology. Various types of stressors alter gut mucosal integrity through different pathways, increasing gut mucosa permeability and promoting bacterial translocation. A denser microbial load in the gut wall emphasizes cytokine production, worsening the disease course. The risk of developing depression and anxiety is higher in IBD patients compared with the general population, and stress is a significant trigger for inducing acute flares of the disease. Conclusions: Further large studies should be conducted to assess the relationship between stressors, psychological disorders, and their impact on the course of IBD. Clinicians involved in the medical care of IBD patients should aim to implement stress reduction practices in addition to pharmacological therapies.

Abstract
Caring for patients with Crohn's disease (CD) is a serious challenge in modern medicine. The increasing incidence of CD among adolescents and the severe course of the disease create the need for new methods of diagnosis and therapy. Endogenous opioids are a group of low molecular weight chemical compounds with analgesic and anti-inflammatory properties. Endorphins, enkephalins, and dynorphins may have potentially beneficial effects on the course of CD. Previous research data on this topic are inconsistent. Some authors have reported an increase in the concentration of leukocytes during the course of inflammatory bowel disease (IBD) while others have described a downward trend, explained by DPP-IV enzyme activity. Even fewer data are available on plasma endo-opioid level. There is also a lack of comprehensive studies that have assessed the endo-opioid system in patients with IBD. Therefore, the objective of this study was to measure the serum concentrations of human β-endorphin, human proenkephalin (A), and human big dynorphin in CD patients in the acute phase of the disease, during hospital treatment, and in the remission state. All determinations were performed using ELISA kits. The results of our study showed that the concentrations of all the tested endo-opioids, especially β-endorphin and proenkephalin (A), were reduced in adolescents with CD compared to those in the healthy control group, during the acute phase of the disease, and in the remission state. Modulation of the endogenous opioid system and the use of selective nonnarcotic agonists of opioid receptors seems to be promising goals in the future treatment of CD.

Abstract
BACKGROUND Psychological stress is a possible factor in the disease course and poor psychosocial outcomes in inflammatory bowel disease (IBD). Understanding the exact relationship between stress and health has been hampered by methodological issues and how stress has been defined and measured. AIMS To explore the association between stress and disease outcomes, investigate the impact of stress on psychosocial outcomes, and evaluate the efficacy of interventions in reducing stress for people with IBD METHODS: We performed a systematic review, searching Medline, CINAHL, Embase and PsycInfo databases on 21 January 2021. We included prospective studies that recruited people with IBD who were aged 16 or over and that measured psychological stress or distress. Analyses included Critical Appraisal Skills Programme quality assessments of included studies and narrative analyses against each research question. RESULTS We reviewed 38 studies with 4757 people with IBD, and included 23 observational and 15 interventional studies using 36 different instruments to measure stress. Perceived stress was the most frequently studied concept and preceded IBD exacerbation. Only three studies examined the relationship between stress and psychosocial factors. Cognitive behavioural interventions may reduce stress and other interventions with disease-specific stress, but more studies are needed where groups have comparable baseline characteristics and potential harms are considered alongside benefits. CONCLUSION Psychological stress appears to precede IBD exacerbation, although what role it plays in psychosocial outcomes and how it is best managed is unclear. Further research needs to examine the differential effects of stress on disease subtypes and IBD in flare and remission.

Abstract
Resilience to stressful life events has received considerable attention in both clinical and preclinical studies. A number of neural substrates have been identified as putatively mediating resilience to stress. However, there remains considerable diversity in how resilience is defined and studied. This article aims to examine how resilience is defined and conceptualized in social psychology, public health, and related fields, to better inform the understanding of stress resilience in the neurobiological context, and to differentiate resilience from other patterns of response to stressful experiences. An understanding of resilience through the lens of clinical and applied sciences is likely to lead to the identification of more robust and reproducible neural substrates, though many challenges remain.

Abstract
The broad role of stress in the brain-gut axis is widely acknowledged, with implications for multiple prevalent health conditions that are characterized by chronic gastrointestinal symptoms. These include the functional gastrointestinal disorders (FGID), such as irritable bowel syndrome and functional dyspepsia, as well as inflammatory bowel diseases (IBD) like ulcerative colitis and Crohn's disease. Although the afferent and efferent pathways linking the gut and the brain are modulated by stress, the fields of neurogastroenterology and psychoneuroendocrinology (PNE)/ psychoneuroimmunology (PNI) remain only loosely connected. We aim to contribute to bringing these fields closer together by drawing attention to a fascinating, evolving research area, targeting an audience with a strong interest in the role of stress in health and disease. To this end, this review introduces the concept of the brain-gut axis and its major pathways, and provides a brief introduction to epidemiological and clinical aspects of FGIDs and IBD. From an interdisciplinary PNE/PNI perspective, we then detail current knowledge regarding the role of chronic and acute stress in the pathophysiology of FGID and IBD. We provide an overview of evidence regarding non-pharmacological treatment approaches that target central or peripheral stress mechanisms, and conclude with future directions, particularly those arising from recent advances in the neurosciences and discoveries surrounding the gut microbiota.

Abstract
RATIONALE, AIMS, AND OBJECTIVES This study aims to examine the smallest detectable change (SDC) and test-retest reliability of the Center for Epidemiologic Studies Depression Scale (CES-D), General Self-Efficacy Scale (GSES), and 12-item General Health Questionnaire (GHQ-12). METHOD We tested 154 young adults at baseline and 2 weeks later. We calculated the intra-class correlation coefficients (ICCs) for test-retest reliability with a two-way random effects model for agreement. We then calculated the standard error of measurement (SEM) for agreement using the ICC formula. The SEM for agreement was used to calculate SDC values at the individual level (SDCind ) and group level (SDCgroup ). RESULTS The study participants included 137 young adults. The ICCs for all self-reported outcome measurement scales exceeded 0.70. The SEM of CES-D was 3.64, leading to an SDCind of 10.10 points and SDCgroup of 0.86 points. The SEM of GSES was 1.56, leading to an SDCind of 4.33 points and SDCgroup of 0.37 points. The SEM of GHQ-12 with bimodal scoring was 1.47, leading to an SDCind of 4.06 points and SDCgroup of 0.35 points. The SEM of GHQ-12 with Likert scoring was 2.44, leading to an SDCind of 6.76 points and SDCgroup of 0.58 points. CONCLUSION To confirm that the change was not a result of measurement error, a score of self-reported outcome measurement scales would need to change by an amount greater than these SDC values. This has important implications for clinicians and epidemiologists when assessing outcomes.

Abstract
AIM: To investigate the relationship between sense of coherence, psychological distress and health related quality of life in inflammatory bowel disease (IBD).
METHODS: This cross-sectional study enrolled a consecutive sample of 147 IBD (aged 45.1 ± 14.1 years; 57.1% female) patients recruited from a tertiary gastroenterology service. Sixty-four participants met diagnostic criteria for Crohn’s disease, while eighty-three patients had ulcerative colitis. Socio-demographic data (education, age, race, gender, gross monthly income and marital status), disease-related variables (illness activity, relapse rate in past 2 years, history of surgery and time since diagnosis), sense of coherence (Antonovsky’s SOC scale), psychological distress symptoms (Hospital Anxiety and Depression Scale) and health-related quality of life (HRQoL; WHOQOL-Bref) were assessed. Hierarchical multiple regression analyses were performed to identify factors that are independently associated with psychological distress and HRQoL in patients with IBD and to provide indications for possible moderating or mediating effects. In addition, formal moderation and mediation analyses (Sobel tests) were performed to confirm potential moderators/mediators of the relationship between SOC, psychological distress symptoms and HRQoL.
RESULTS: Lower SOC scores (std beta= -0.504; P < 0.001), female gender (std beta = 0.176; P = 0.021) and White race (std beta = 0.164; P = 0.033) were independently associated with higher levels of depressive symptoms, while lower levels of SOC (std beta = -0.438; P < 0.001) and higher relapse rate (std beta = 0.161; P = 0.033) were independently associated with more severe anxiety symptoms. A significant interaction between time since diagnosis and SOC was found with regard to the severity of depressive or anxiety symptoms, as the interaction term (time since diagnosis X SOC) had beta coefficients of -0.191 (P = 0.009) and -0.172 (P = 0.026), respectively. Lower levels of anxiety symptoms (std beta = -0.369; P < 0.001), higher levels of SOC (std beta = 0.231; P = 0.016) and non-White race (std beta = -0.229; P = 0.006), i.e., mixed-race, which represented the reference category, were independently associated with higher levels of overall HRQoL. Anxiety symptoms were the most potent independent correlate of most aspects of HRQoL. In addition, anxiety mediated the association between SOC and satisfaction with health, as well as its relationship with physical, mental, and social relations HRQoL. Depressive symptoms also mediated the association between SOC and mental HRQoL.
CONCLUSION: Our data indicated that SOC is an important construct, as it influences psychological distress and has significant albeit indirect effects on several HRQoL domains in IBD.

Abstract
Background and Aim. Sense of coherence (SOC) is a health-promoting concept reflecting a person's view of life and response to stressful situations and may be of importance in coping with chronic illness. The aim of this study was to explore associations between SOC and sociodemographic, disease-related, and personal characteristics in a sample of patients with inflammatory bowel disease (IBD). Methods. Measures included sociodemographic and disease-related data, the Sense of Coherence Scale, General Self-Efficacy Scale (GSE), and Fatigue Severity Scale (FSS-5). Results. In total, 428 IBD patients had evaluable questionnaires (response rate 93%). The overall mean SOC total score was 66.25 (SD 11.47) and with no statistically significant difference between patients with ulcerative colitis (UC) and patients with Crohn's disease (CD). In the multivariate analyses, higher GSE scores were significantly associated with higher SOC scores and higher FSS-5 scores were significantly associated with lower SOC scores in both UC and CD. Conclusion. GSE and FSS-5 contributed more to the variance in SOC than sociodemographic and disease-related variables. Longitudinal studies are warranted to investigate the value of SOC as a predictor of disability, medication adherence, coping behavior, and health-related quality of life.

Abstract
AIM Sense of Coherence (SOC) is hypothesized to have direct physiological consequences on endocrine and immunological processes. In this study, we compare parental SOC scores from pregnancy in groups of infants and parents representing different lifestyles (anthroposophic, partly anthroposophic and nonanthroposophic). We also analyse whether these could predict cortisol levels of the parents and their infants at 6-24 months postpartum. METHODS Parental SOC-13 was collected during the third trimester of pregnancy from a birth cohort of families with different lifestyles. Salivary samples were collected from the whole family when the child was 6 months (n = 210), 12 (n = 178) and 24 months of age (n = 149), and cortisol levels were analysed with radioimmunoassay technique. RESULTS Sense of Coherence scores did not differ between the three lifestyle groups, and there were no correlations between SOC scores and salivary cortisol concentrations in separate analyses of mothers, fathers and children at any sampling age or at any sampling time during the day (morning, afternoon, bedtime). CONCLUSION Sense of Coherence scores did not vary in parents with different lifestyles and were not associated with salivary cortisol levels in parents or in children.

Abstract
The role of psychological distress and personality as predisposing factors for the development of inflammatory bowel disease (IBD) remains controversial. Attempts to investigate the role of psychological factors in IBD exhibited rather conflicting results. Among the studies concerning the effects of stress or depression on the course of IBD, the majority suggest that stress worsened IBD, the rest giving either negative or inconclusive results. However, application of strategies, including avoidance of coping and training patients in problem solving or emotion-oriented, could influence the course of IBD. Large controlled clinical trials are needed in order to clarify the impact of psychological interventions on the quality of life and the course of disease.

Abstract
BACKGROUND Research examining the role of stress in gastrointestinal (GI) symptoms such as chronic abdominal pain (CAP) is controversial. The purpose of this study was to examine the expression of genes involved in metabolic stress and toxicity in men and women with high and low levels of perceived stress with and without CAP. METHODS Data and samples were collected and the expression of genes involved in metabolic stress and toxicity was analyzed in 26 individuals who had consented to participate in a natural history protocol. Subjects completed the 10-item Perceived Stress scale (PSS). Fasting participants' peripheral whole blood was collected for proteomic and genomic studies. Polymerase chain reaction (PCR) array was used to analyze the expression of 84 key genes involved in human stress and toxicity plus 5 housekeeping genes. Plasma interleukin-1 alpha (IL-1α) protein was quantified via enzyme-linked immunosorbent assay (ELISA). RESULTS Interleukin-1 alpha gene (IL1A) was upregulated in females with high stress versus females with low stress by 2.58-fold (95% CI [0.88, 4.28]). IL1A was upregulated in participants with high stress and CAP versus those with low stress and CAP by 3.47-fold (95% CI [1.14, 5.80]). CONCLUSIONS An upregulation of the gene coding the pro-inflammatory cytokine IL-1α suggests that the mechanism behind stress-related changes in GI symptoms is pro-inflammatory in nature. The results of this study contribute to the knowledge of the mechanism behind stress-related CAP symptoms and gender differences associated with these disorders.
