The treatment strategy for ulcerative colitis [UC] is mainly based on the severity, distribution [proctitis, left-sided, extensive]¹ and pattern of disease. The latter includes relapse frequency, disease course, response to previous medications, side effects of medication, and extra-intestinal manifestations. Age at onset, and disease duration are also important factors. It is important to distinguish patients with severe UC necessitating hospital admission from those with mild or moderately active disease who can be managed as outpatients. The best validated and most widely used index for identifying severe UC remains that of Truelove and Witts.² Patients with bloody stool frequency ≥ 6/day and a tachycardia [> 90 min⁻¹], or temperature > 37.8°C, or anaemia [haemoglobin < 10.5 g/dl], or an elevated erythrocyte sedimentation rate [ESR] [> 30 mm/h] have severe UC. Only one additional criterion in addition to the bloody stool frequency ≥ 6/day is needed to define a severe attack.^3,4 In practice, a C-reactive protein [CRP] of 30 mg/l can be substituted for the ESR.

Objective Histological remission is being increasingly acknowledged as a therapeutic endpoint in patients with UC. The work hereafter described aimed to evaluate the concordance between three histological classification systems—Geboes Score (GS), Nancy Index (NI) and RobartsHistopathologyIndex (RHI), as well as to evaluate their association with the endoscopic outcomes and the faecal calprotectin (FC) levels. Design Biopsy samples from 377 patients with UC were blindly evaluated using GS, NI and RHI. The results were compared with the patients’ Mayo Endoscopic Score and FC levels. Result GS, NI and RHI have a good concordance concerning the distinction between patients in histological remission or activity. RHI was particularly close to NI, with 100% of all patients classified as being in remission with NI being identified as such with RHI and 100% of all patients classified as having activity with RHI being identified as such with NI. These scores could also predict the Mayo Endoscopic Score and the FC levels, with their sensitivity and specificity levels depending on the chosen cut-offs. Moreover, higher FC levels were statistically associated with the presence of neutrophils in the epithelium, as well as with ulceration or erosion of the intestinal mucosa. Conclusions GS, NI and RHI histopathological scoring systems are comparable in what concerns patients’ stratification into histological remission/activity. Additionally, FC levels are increased when neutrophils are present in the epithelium and the intestinal mucosa has erosions or ulcers. The presence of neutrophils in the epithelium is, indeed, the main marker of histological activity.

Background: A simplified magnetic resonance enterography (MRe) index (sMARIA) for Crohn’s disease (CD) was recently developed and validated.Objective: Our aims were (a) to assess sMARIA’s accuracy in a sample other than the validation cohort; (b) to evaluate its correlation with a simpler endoscopy index (SES‐CD) and fecal calprotectin (FC); and (c) to assess the need of an expert radiologist to reliably use sMARIA.Methods: Patients with CD who underwent MRe, ileocolonoscopy and FC within 2–4 weeks had their MRe retrospectively reviewed by two blinded raters. Disease activity was evaluated through sMARIA, SES‐CD and FC. sMARIA’s accuracy, indices correlation, and interrater reliability were assessed.Results: In total, 84 patients were included, comprising 420 intestinal segments evaluations. sMARIA ≥1 accurately identified segments with active disease (90% sensitivity, 98% specificity; area under the curve 0.94, 95% confidence interval (CI) 0.91–0.97; p < 0.01). sMARIA correlated with endoscopy, both for ileal and colonic segments (R = 0.94 and R = 0.82; p < 0.01). Per patient, there was a strong correlation between sMARIA, endoscopy (R = 0.95; p < 0.01) and FC (R = 0.91; p < 0.01). Interrater agreement was excellent (intraclass correlation coefficient 0.95; 95% CI 0.94–0.96; p < 0.01).Conclusion: sMARIA accurately measured CD activity using SES‐CD as standard of reference, and exhibited high correlation with a simple endoscopic index and a biomarker. The interrater reliability between a radiology resident and an expert was excellent.

Objective: Endoscopy is healthcare’s third largest generator of medical waste in hospitals. This prospective study aimed to measure a single unit’s waste carbon footprint and perform a pioneer intervention towards a more sustainable endoscopy practice. The relation of regulated medical waste (RMW; material fully contaminated with blood or body fluids or containing infectious agents) versus landfill waste (non-recyclable material not fully contaminated) may play a critical role. Design: In a four-stage prospective study, following a 4-week observational audit with daily weighing of both waste types (stage 1), stage 2 consisted of a 1-week intervention with team education of waste handling. Recycling bins were placed in endoscopy rooms, landfill and RMW bins were relocated. During stages 3 (1 month after intervention) and 4 (4 months after intervention), daily endoscopic waste was weighed. Equivalence of 1 kg of landfill waste to 1 kg carbon dioxide equivalent (CO _2e ) and 1 kg of RMW to 3kgCO _2e was assumed. Paired samples t-tests for comparisons. Results: From stage 1 to stage 3, mean total waste and RMW were reduced by 12.9% (p=0.155) and 41.4% (p=0.010), respectively, whereas landfill (p=0.059) and recycling waste increased (paper: p=0.001; plastic: p=0.007). While mean endoscopy load was similar (46.2 vs 44.5, p=0.275), a total decrease of CO _2e by 31.6% (138.8kgCO _2e ) was found (mean kgCO _2e 109.7 vs 74.9, p=0.018). The annual reduction was calculated at 1665.6kgCO _2e . All these effects were sustained 4 months after the intervention (stage 4) without objections by responsible endoscopy personnel. Conclusion: In this interventional study, applying sustainability measures to a real-world scenario, RMW reduction and daily recycling were achieved and sustained over time, without compromising endoscopy productivity.

The impact of inflammatory bowel disease (IBD) on sexual health is a leading concern among patients. Most studies focus on sexual dysfunction rather than patient-perceived sexual quality of life (SQoL). We aimed to assess SQoL in IBD patients compared with healthy controls. This is a multicenter, cross-sectional study of IBD patients (n = 575 with Crohn’s disease and n = 294 with ulcerative colitis), compared with healthy controls (n = 398), that used an anonymous self-administered questionnaire. This multimodal questionnaire included sociodemographic data and 4 validated instruments: Short IBD Questionnaire, Social Desirability Scale, Sexual QoL Questionnaire–Male/Female, Nine-item Patient Health Questionnaire. Inflammatory bowel disease patients reported lower SQoL (men: 77.29 vs 83.83; P < 0.001; women: 70.40 vs 81.63; P < 0.001) compared with controls. Among IBD patients, SQoL was positively correlated with health-related quality of life (HRQoL) and negatively correlated with depression symptoms. Perianal disease was associated with lower HRQoL and higher incidence of depression, but only impacted SQoL in men. In linear regression analysis for men, SQoL was associated with age, marital status, and depression (β, –2.101; 95% confidence interval [CI], –2.505 to –1.696; P < 0.001). In women, SQoL was associated with depression (β, –1.973; 95% CI, –2.313 to –1.632; P < 0.001) only. Patients with IBD had impaired SQoL compared with healthy controls. Age, widow status, and depression were independent predictors of SQoL in men with IBD, whereas in women depression was the only independent predictor. Emotional and self-esteem issues were the main concerns reported by IBD patients regarding sexual health.
