Abstract
OBJECTIVE Clinical studies commonly use disease-specific measures to assess patients' health-related quality of life. However, economic evaluation often requires preference-based utility index scores to calculate cost per quality-adjusted life-year (QALY). When utility index scores are not directly available, mappings are useful. To our knowledge, no mapping exists for the Short Inflammatory Bowel Disease Questionnaire (SIBDQ). Our aim was to develop a mapping from SIBDQ to the EQ-5D-5L index score with German weights for inflammatory bowel disease (IBD) patients. METHODS We used 3856 observations of 1055 IBD patients who participated in a randomised controlled trial in Germany on the effect of introducing regular appointments with an IBD nurse specialist in addition to standard care with biologics. We considered five data availability scenarios. For each scenario, we estimated different regression and machine learning models: linear mixed-effects regression, mixed-effects Tobit regression, an adjusted limited dependent variable mixture model and a mixed-effects regression forest. We selected the final models with tenfold cross-validation based on a model subset and validated these with observations in a validation subset. RESULTS For the first four data availability scenarios, we selected mixed-effects Tobit regressions as final models. For the fifth scenario, mixed-effects regression forest performed best. Our findings suggest that the demographic variables age and gender do not improve the mapping, while including SIBDQ subscales, IBD disease type, BMI and smoking status leads to better predictions. CONCLUSION We developed an algorithm mapping SIBDQ values to EQ-5D-5L index scores for different sets of covariates in IBD patients. It is implemented in the following web application: https://www.bwl.uni-hamburg.de/hcm/forschung/mapping.html .

Abstract
Ulcerative colitis (UC) is an inflammatory bowel disease, and is characterized by the diffuse inflammation and ulceration in the colon and rectum mucosa, even extending to the caecum. Epigenetic modifications, including DNA methylations, histone modifications and non-coding RNAs, are implicated in the differentiation, maturation, and functional modulation of multiple immune and non-immune cell types, and are influenced and altered in various chronic inflammatory diseases, including UC. Here we review the relevant studies revealing the differential epigenetic features in UC, and summarize the current knowledge about the immunopathogenesis of UC through epigenetic regulation and inflammatory signaling networks, regarding DNA methylation, histone modification, miRNAs and lncRNAs. We also discuss the epigenetic-associated therapeutic strategies for the alleviation and treatment of UC, which will provide insights to intervene in the immunopathological process of UC in view of epigenetic regulation.

Abstract
INTRODUCTION This study describes the epidemiological, clinical, patient-reported and economic burden of inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), in Spain. METHODS A systematic review was performed of observational studies reporting the epidemiological, clinical, patient-reported and economic burden of IBD in the Spanish population, from 2011 to 2021. Original articles and conference abstracts published in English or Spanish were eligible. RESULTS A total of 45 publications were included in the review. The incidence of IBD in adults ranged from 9.6 to 44.3 per 100,000 inhabitants (4.6 to 18.5 for CD and 3.4 to 26.5 for UC). The incidence increased between 1.5- and twofold from 2000 to 2016 (regionally). Up to 6.0% (CD) and 3.0% (UC) IBD-associated mortality was reported. Disease onset predominantly occurs between 30 and 40 years (more delayed for UC than CD). Most frequently reported gastrointestinal manifestations are rectal bleeding in UC and weight loss in CD. Extraintestinal manifestations (EIM) have been described in up to 47.4% of patients with CD and 48.1% of patients with UC. Psychiatric comorbidities were frequently reported in both CD and UC (depression up to 20% and anxiety up to 11%). Reduced health-related quality of life (HRQoL) compared to the general population was reported. Significant symptomatology was associated with high levels of anxiety, depression, stress and lower HRQoL. Main healthcare resources reported were emergency department visits (24.0%), hospitalization (14.7%), surgery (up to 11%) and use of biologics (up to 60%), especially in CD. Direct and indirect annual costs per patient with UC were €1754.1 and €399.3, respectively. CONCLUSION Patients with CD and UC present a high disease burden which negatively impacts their HRQoL, leading to elevated use of resources.

Abstract
BACKGROUND The societal burden of inflammatory bowel diseases (IBD) is not well documented, and further studies are needed to quantify the costs of the disease state. Thus, the aim was to estimate the societal burden and identify its predictors. METHODS A cross-sectional questionnaire-based study complemented by objective data from patient medical records was performed for patients with Crohn's disease (CD) and ulcerative colitis (UC). RESULTS We analyzed data from 161 patients (CD: 102, UC: 59). The overall work impairment reached 15.4%, 11.2% vs. 28.8% without/with self-reported symptoms (p = 0.006). Daily activity impairment was 19.3%, 14.1% vs. 35.6% (p < 0.001). The disability pension rate was 28%, 23% vs. 44% (p = 0.012). The total productivity loss due to absenteeism, presenteeism, and disability amounted to 7,673 €/patient/year, 6,018 vs. 12,354 €/patient/year (p = 0.000). Out-of-pocket costs amounted to 562 €/patient/year, 472 vs. 844 €/patient/year (p = 0.001). Self-reported symptoms were the strongest predictor of costs (p < 0.001). CONCLUSION We found a high societal burden for IBD and a significant association between patient-reported disease symptoms and work disability, daily activity impairment, disability pensions, and out-of-pocket costs. Physician-reported disease activity is not a reliable predictor of costs except for out-of-pocket expenses.

Abstract
Aim. Ulcerative colitis (UC) is a refractory gastrointestinal disease. The study aimed to expound the mechanism of Polygonum bistorta (PB) in treating UC by network pharmacology, molecular docking, and experiment verification. Methods. The compositions and targets of PB and UC-associated targets were obtained by searching the websites and the literature. The potential mechanism of PB in the treatment of UC was predicted by protein-protein interaction network construction, Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis. Molecule docking was performed by AutoDock. In vitro experiments explored the mechanism of quercetin (Que), the main active composition of PB, in treating UC. Results. Six compositions, 139 PB targets, and 934 UC-associated targets were obtained. 93 overlapping targets between PB and UC were identified, and 18 of them were the core targets. 467 biological processes, 10 cell components, and 30 molecular functions were obtained by GO analysis. 102 pathways were enriched through KEGG analysis. Among them, the IL-17 signaling pathway had high importance. The core targets FOS, JUN, IL-1β, CCL2, CXCL8, and MMP9 could dock with Que successfully. Act1, TRAF6, FOS, and JUN were identified by KEGG as the key proteins of the IL-17 signaling pathway. The expressions of the abovementioned proteins were increased in Caco-2 cells stimulated by Dextran sulfate sodium and decreased after being treated by Que. Conclusion. PB might treat UC by downregulating the IL-17 signaling pathway. It is worth doing further research on PB treating UC in vivo.

Abstract
BACKGROUND National studies report a high variability of indirect costs of inflammatory bowel disease (IBD). In this study, selected aspects of the societal burden of IBDs were compared between 12 European countries. METHODS A questionnaire-based study among adult patients with IBD was performed. Data on patient characteristics, productivity loss, and informal care were collected. The costs of productivity loss were assessed from the social perspective. The cost of absenteeism and presenteeism was valuated using the gross domestic product per worker. Informal care was measured by time inputs of relatives and friends to assist patients. Productivity loss among informal caregivers outside their paid work was valuated with the average wage. The results were adjusted for confounders and multiplicity. RESULTS Responses from 3687 patients (67% employed) were analyzed. Regular activity (outside paid work) impairment did not differ between countries, but a significant difference in informal care and productivity loss was observed. There were no differences in indirect costs between the types of IBD across the countries. The mean annual cost of absenteeism, presenteeism, and informal care varied from €1253 (Bulgaria) to €7915 (Spain), from €2149 (Bulgaria) to €14 524 (Belgium), and from €1729 (Poland) to €12 063 (Italy), respectively. Compared with patients with active disease, those with IBD in remission showed a lower indirect cost by 54% (presenteeism, P < .001) or 75% (absenteeism, informal care, P < .001). CONCLUSIONS The study showed a high relevance of the indirect cost of IBD in the context of economic evaluation, as well as a between-country variability of work-related impairment or informal care.
