Anaemia is an important complication of inflammatory bowel disease [IBD]. The aim of this study was to determine the prevalence of anaemia and the practice of anaemia screening during the first year following diagnosis, in a European prospective population-based inception cohort. Newly diagnosed IBD patients were included and followed prospectively for 1 year in 29 European and one Australian centre. Clinical data including demographics, medical therapy, surgery and blood samples were collected. Anaemia was defined according to the World Health Organization criteria. A total of 1871 patients (Crohn’s disease [CD]: 686, 88%; ulcerative colitis [UC]: 1,021, 87%; IBD unclassified [IBDU] 164. 81%) were included in the study. The prevalence of anaemia was higher in CD than in UC patients and, overall, 49% of CD and 39% of UC patients experienced at least one instance of anaemia during the first 12 months after diagnosis. UC patients with more extensive disease and those from Eastern European countries, and CD patients with penetrating disease or colonic disease location, had higher risks of anaemia. CD and UC patients in need of none or only mild anti-inflammatory treatment had a lower risk of anaemia. In a significant proportion of patients, anaemia was not assessed until several months after diagnosis, and in almost half of all cases of anaemia a thorough work-up was not performed. Overall, 42% of patients had at least one instance of anaemia during the first year following diagnosis. Most patients were assessed for anaemia regularly; however, a full anaemia work-up was frequently neglected in this community setting.

Background and aim Inflammatory bowel disease (IBD) has been associated with genetic and environmental factors, including urban living. IBD was rare in the Israeli Bedouin community 30 years ago. Over recent decades, a large proportion of this community has undergone a transition from a nomadic to a western lifestyle. Our aim was to carry out an updated evaluation of the clinical and epidemiological features of IBD in the Bedouin sector of southern Israel. Methods All Bedouin patients with a known diagnosis of Crohn’s disease (CD) or ulcerative colitis (UC) were included in the retrospective study. Results The cohort included 31 CD patients and 31 UC patients. The mean age of the patients at diagnosis was 29±10.9 and 35±17.5 years for CD and UC, respectively. The prevalence rate for CD was 15.5/100 000 and the incidence rate was 0.8–3.55/100 000. Fourteen of the CD patients (45%) had ileal disease and 64.5% had inflammatory disease behavior according to the Montreal classification. Eleven of the CD patients (35%) were treated with anti-TNF-α and 26% had undergone surgery. Over the previous decade, the prevalence of UC was 14/100 000 and the incidence was 0.5–2.39/100 000. Eighteen UC patients (58%) had left-sided colitis. Three (9.7%) had undergone total colectomy for severe disease. Conclusion We found an increased prevalence of IBD in the Bedouin population, associated with their change in lifestyle over previous decades. However, the prevalence is still markedly lower than that in other population groups. A high percentage of patients were treated with anti-TNF-α and/or surgery.

Summary: Background: Chronic abdominal pain and fatigue are characteristics of Crohn's disease (CD) and contribute to functional impairments.Aims: To examine whether CD‐tailored cognitive‐behavioural and mindfulness intervention (COBMINDEX) is effective in reducing abdominal pain and fatigue in patients with CD and whether changes in abdominal pain and fatigue mediate any beneficial effects of COBMINDEX on impairments in work productivity and daily activities.Methods: This is a secondary analysis of a parallel‐group multicentre randomised controlled trial. Patients with mild‐to‐moderate CD (n = 142) were randomised into either intervention group receiving COBMINDEX, or control group receiving treatment‐as‐usual for 3 months followed by COBMINDEX. Complete data were collected from 120 patients (34.0 ± 10.7 years, 62.5% female, intervention = 60, control = 60). Analysis of covariance assessed group differences in 3‐month follow‐up scores, controlling for baseline scores. Multiple parallel mediation analysis assessed the proposed mechanisms for the entire sample.Results: The intervention group demonstrated significantly lower levels of abdominal pain (F = 17.46, p < 0.001, η2p = 0.13), fatigue (F = 7.26, p = 0.008, η2p = 0.06) and impairments at work (F = 4.82, p = 0.032, η2p = 0.07) and daily activities (F = 6.26, p = 0.014, η2p = 0.05), compared with treatment‐as‐usual. Moreover, changes in abdominal pain and fatigue significantly mediated the beneficial effects of COBMINDEX on patients' work productivity (b = −9.90, SE = 2.86, 95% CI: −16.11 to −4.94) and daily activities (b = −9.65, SE = 1.91, 95% CI: −13.77 to 6.35), independent of changes in disease activity.Conclusions: COBMINDEX is effective at reducing abdominal pain and fatigue in patients with CD, which in turn leads to improvement in functioning. Clinicians should incorporate screening for severe abdominal pain and fatigue and consider offering cognitive‐behavioural and mindfulness training.ClinicalTrials.gov, Number: NCT05085925.

Background and Objective: Crohn’s Disease (CD) is a chronic inflammatory condition with significant physical and psychological impacts, often requiring comprehensive self-management. This study examines the effects of COBMINDEX (Cognitive–Behavioral and Mindfulness Intervention with Daily Exercise) on coping strategies and life satisfaction in CD patients, focusing on gender-specific responses. Study objectives were to assess the impact of COBMINDEX on adaptive and maladaptive coping strategies and life satisfaction in CD patients, and to examine gender differences in these outcomes. Materials and Methods: A pre-planned secondary analysis of a randomized controlled trial, conducted from 2018 to 2021, at two public tertiary hospitals in Israel. A total of 120 CD patients (45 men and 75 women) were randomly assigned to either theCOBMINDEX group or a wait-list control group. Participants were assessed at baseline and post-intervention for coping strategies, mindfulness, psychological symptoms, and life satisfaction using validated scales. Quantile regression explored the gender-specific predictors of life satisfaction. This study was registered at ClinicalTrials.gov (NCT05085925) and Israel Ministry of Health (MOH_2020- 02- 24_008721. asp). Results: Both genders showed significant improvements in mindfulness, emotion-focused coping, and active coping (p < 0.05). Women exhibited reduced dysfunctional coping and greater emotional support use. For men, emotion-focused coping and mindfulness positively predicted life satisfaction, while for women, reductions in psychological symptoms and dysfunctional coping were significant predictors (p < 0.01). Conclusions: COBMINDEX enhances coping strategies and life satisfaction in CD patients, with notable gender differences. These findings highlight the importance of gender-tailored psychological interventions to improve overall patient well-being.

The COVID-19 crisis poses challenges to healthcare systems and requires micro- and macro-organizational adaptations. This study examined the organizational atmosphere in Israeli hospitals by evaluating workers’ perceptions and concerns about the COVID-19 crisis and its management. At the end of the pandemic’s first wave in Israel, 547 healthcare workers responded to an online survey, which inquired about COVID-19 concerns at the individual and family level, perceptions at the national and organizational level, perceptions of the way the crisis was managed, self-assessment of coping with the crisis and burnout, and demographics. Findings showed that healthcare workers expressed deep concerns for family members and apprehension at a national level. Respondents noted that they were coping well with the crisis while expressing negative perceptions of how the crisis was managed. A regression model showed that the low self-assessment of medical staff of coping with the crisis, deep concerns at the organizational level, negative perceptions of crisis management, and providing care for COVID-19 patients were predictors of burnout. The findings emphasize the importance of developing a supportive organizational culture for hospital workers. Awareness of their concerns and perceptions is essential to improve organizational culture and healthcare systems’ ability to continue fighting the virus and confront future health crises.
