Abstract
Background Clinical decision support systems (CDSSs) embedded in electronic medical records (EMRs), also called electronic health records, have the potential to improve the adoption of clinical guidelines. The University of Alberta Inflammatory Bowel Disease (IBD) Group developed a CDSS for patients with IBD who might be experiencing disease flare and deployed it within a clinical information system in 2 continuous time periods. Objective This study aims to evaluate the impact of the IBD CDSS on the adherence of health care providers (ie, physicians and nurses) to institutionally agreed clinical management protocols. Methods A 2-period interrupted time series (ITS) design, comparing adherence to a clinical flare management protocol during outpatient visits before and after the CDSS implementation, was used. Each interruption was initiated with user training and a memo with instructions for use. A group of 7 physicians, 1 nurse practitioner, and 4 nurses were invited to use the CDSS. In total, 31,726 flare encounters were extracted from the clinical information system database, and 9217 of them were manually screened for inclusion. Each data point in the ITS analysis corresponded to 1 month of individual patient encounters, with a total of 18 months of data (9 before and 9 after interruption) for each period. The study was designed in accordance with the Statement on Reporting of Evaluation Studies in Health Informatics (STARE-HI) guidelines for health informatics evaluations. Results Following manual screening, 623 flare encounters were confirmed and designated for ITS analysis. The CDSS was activated in 198 of 623 encounters, most commonly in cases where the primary visit reason was a suspected IBD flare. In Implementation Period 1, before-and-after analysis demonstrates an increase in documentation of clinical scores from 3.5% to 24.1% (P<.001), with a statistically significant level change in ITS analysis (P=.03). In Implementation Period 2, the before-and-after analysis showed further increases in the ordering of acute disease flare lab tests (47.6% to 65.8%; P<.001), including the biomarker fecal calprotectin (27.9% to 37.3%; P=.03) and stool culture testing (54.6% to 66.9%; P=.005); the latter is a test used to distinguish a flare from an infectious disease. There were no significant slope or level changes in ITS analyses in Implementation Period 2. The overall provider adoption rate was moderate at approximately 25%, with greater adoption by nurse providers (used in 30.5% of flare encounters) compared to physicians (used in 6.7% of flare encounters). Conclusions This is one of the first studies to investigate the implementation of a CDSS for IBD, designed with a leading EMR software (Epic Systems), providing initial evidence of an improvement over routine care. Several areas for future research were identified, notably the effect of CDSSs on outcomes and how to design a CDSS with greater utility for physicians. CDSSs for IBD should also be evaluated on a larger scale; this can be facilitated by regional and national centralized EMR systems.

Abstract
Background Despite recent emerging literature involving the utility of endoscopic balloon dilation (EBD) of strictures via balloon-assisted endoscopy (BAE), specifically regarding the management of Crohn's disease (CD), the optimal clinical approach with balloon systems has been largely neglected in academic literature. Objectives This study assesses the intra-procedural success and safety of EBD via BAE for small bowel CD strictures while detailing our clinical approach and technique. Secondarily, we compare the single-balloon endoscope (SBE) and double-balloon endoscope (DBE) systems for EBD-related outcomes. Design Retrospective consecutive patient cohort analysis. Methods We retrospectively assessed a consecutive small bowel CD patient cohort undergoing BAE at the University of Alberta Hospital endoscopy unit from 2013 to 2020. The primary endpoint discerned the safety and immediate success rate of EBD during endoscopy, and comparisons of the dilation parameters and efficacy of SBE versus DBE were assessed as secondary outcomes. Results During the study period, 87 patients (44 male) with a mean age of 56 ± 14.7 years underwent 179 endoscopic procedures (92 DBE and 87 SBE). Of 358 strictures encountered, 320 (89.4%) were successfully dilated and traversed. The mean maximum dilation diameter was 15.76 ± 2.10 mm. There were no perforations or major adverse events. Conclusion EBD via BAE is a safe procedure in small bowel CD with a high intraprocedural success rate. Overall, SBE had a higher success rate in traversing strictures before and after dilation using our technique. This analysis is limited by the retrospective nature of our study and must be balanced against the inherent benefits of the DBE system.

Abstract
Our traditional approach to diagnosis, prognosis, and treatment, can no longer process and transform the enormous volume of information into therapeutic success, innovative discovery, and health economic performance. Precision health, i.e., the right treatment, for the right person, at the right time in the right place, is enabled through a learning health system, in which medicine and multidisciplinary science, economic viability, diverse culture, and empowered patient's preferences are digitally integrated and conceptually aligned for continuous improvement and maintenance of health, wellbeing, and equity. Artificial intelligence (AI) has been successfully evaluated in risk stratification, accurate diagnosis, and treatment allocation, and to prevent health disparities. There is one caveat though: dependable AI models need to be trained on population-representative, large and deep data sets by multidisciplinary and multinational teams to avoid developer, statistical and social bias. Such applications and models can neither be created nor validated with data at the country, let alone institutional level and require a new dimension of collaboration, a cultural change with the establishment of trust in a precompetitive space. The Data for Health (#DFH23) conference in Berlin and the Follow-Up Workshop at Harvard University in Boston hosted a representative group of stakeholders in society, academia, industry, and government. With the momentum #DFH23 created, the European Health Data Space (EHDS) as a solid and safe foundation for consented collaborative health data use and the G7 Hiroshima AI process in place, we call on citizens and their governments to fully support digital transformation of medicine, research and innovation including AI.

Abstract
OBJECTIVES The tracking and documentation of procedures in gastrointestinal endoscopy including therapeutic interventions is an essential but challenging process. The University of Alberta has developed a smartphone app to help facilitate this task. This study evaluated the functionality, usefulness, and user satisfaction of this app. METHODS Four Gastroenterology (GI) residents and two therapeutic endoscopy fellows participated in the study. The trainees submitted all their data into the app from the procedures in which they participated hands-on for one year, data was collected and analyzed on the app and the website associated with it. RESULTS Trainees were able to register the procedures immediately after each procedure without difficulty, this data was available to be reviewed at anytime in the app and associated website. Furthermore, the data collected was able to be transformed into tables and graphs on the app website. The total number of procedures and therapeutic interventions performed were easily accessed in the app and website at anytime. The app facilitated the calculation of the cecal intubation rate in colonoscopy and the cannulation rate in ERCP for the therapeutic endoscopy trainee. Trainees reported excellent experience with the app capabilities. CONCLUSIONS A novel smartphone app was useful in collecting meaningful data submitted by gastrointestinal endoscopy trainees, furthermore, through an associated website, it was capable to create graphs and tables to show and facilitate the calculation of meaningful data such as key performance indicators.

Abstract
Background Ulcerative colitis (UC) is a chronic inflammatory disease of the colon which requires ongoing medical therapy. The therapeutic options for moderate-to-severe UC include biologics and small molecules, which are effective but come with a significant cost. As such, their exact positioning in the therapeutic algorithm remains unclear. Purpose The aim of our study was to assess and compare the cost-effectiveness of infliximab, adalimumab, vedolizumab, golimumab, ustekinumab and tofacitinib for the management of moderate-to-severe UC from the perspective of the Canadian public healthcare system. Method A Markov model was constructed to simulate the disease course of UC patients after initiating each available therapy. Drug costs were obtained from the Alberta Health Drug Benefit List and the remaining costs were determined from the CIHI Patient Cost Estimator. Transition probabilities were obtained from a review of the literature, and loss of response and complication rates were obtained from randomized controlled trials. Our main analysis used a time horizon of 5 years, and time horizons of 1- and 10-years were also assessed in our sensitivity analysis. Probabilistic sensitivity analysis was performed to characterize uncertainty related to all parameters. Result(s) Infliximab costs $26,611 per quality-adjusted life year (QALY) using a 5-year time horizon. Adalimumab costs $20,783 per QALY. Vedolizumab costs $40,553 per QALY. Golimumab costs $34,316 per QALY. Ustekinumab costs $26,366 per QALY. Lastly, tofacitinib costs $25,572 per QALY. At a willingness-to-pay threshold of $50,000 per QALY, sensitivity analysis revealed that infliximab, adalimumab, vedolizumab, golimumab, ustekinumab and tofacitinib had a 36%, 12%, 1%, 1%, 44% and 6% probability of being cost-effective, respectively. Conclusion(s) Our economic model concluded that adalimumab is the most cost-effective first-line therapy for UC patients who have failed conventional therapy.

Abstract
BACKGROUND AND AIMS Corticosteroid-free remission is a primary treatment goal in IBD which may be achieved with greater use of anti-TNF therapy. We defined temporal trends of corticosteroid use, anti-TNF use, hospitalization and surgery in a prevalent IBD cohort within the province of Alberta, Canada. METHODS Health administrative data were used to identify medication dispensing, hospitalizations and surgery in individuals with IBD from 2010 to 2015. Temporal trends were calculated using log-binomial regression for medications and log-linear models for hospitalizations and surgery rates. Analyses were stratified based on geographic location. RESULTS Of 28890 individuals with IBD, 50.3% had Crohn's disease. One in six individuals (15.45%) were dispensed a corticosteroid. Corticosteroid use decreased in both metropolitan areas (AAPC -20.08%, 95% CI: -21.78 to -18.04) and non-metropolitan areas (AAPC -18.14%, 95% CI: -20.78 to -18.04) with a similar pattern for corticosteroid dependence. Corticosteroid dependence was more prevalent in UC vs. CD (P < 0.05), and in the pediatric IBD cohort (13.45) compared to the adult (8.89) and elderly (7.54) cohorts (per 100 prevalent population, P < 0.001). The proportion of individuals dispensed an anti-TNF increased over the study period (AAPC 12.58%, 95% CI: 11.56 to 13.61). Significantly more non-metropolitan versus metropolitan residing individuals were hospitalized for any reason, for an IBD-related, or IBD-specific indication (all P < 0.001) though the proportion requiring IBD surgery was similar between groups. CONCLUSIONS An increase in anti-TNF use corresponded to a decline in corticosteroid use and dependence in those with IBD. Inequities in IBD care still exist based on location and age.

Abstract
BACKGROUND Psychological stress negatively impacts inflammatory bowel disease (IBD) outcomes. Patients have prioritized access to online interventions; yet, the data on these have been limited by mixed in-person/online interventions, low adherence, and non-randomized controlled trial (RCT) design. OBJECTIVES We assessed the efficacy of and adherence to a 12-week online multicomponent stress reduction intervention in IBD. DESIGN This is a RCT. METHODS Adult participants on stable IBD medical therapy with elevated stress levels from four centers were randomized to intervention or control groups. Intervention participants received a 12-week online program including a weekly yoga, breathwork and meditation video (target 2-3 times/week), a weekly cognitive behavioral therapy/positive psychology informed video activity, and weekly 10-min check-ins by a study team member. Control participants received weekly motivational messages by email. All patients received standard of care IBD therapy. The primary outcome was Cohen's Perceived Stress Scale (PSS). Secondary outcomes evaluated mental health, resilience, health-related quality of life (HRQoL), symptom indices, acceptability, adherence, and inflammatory biomarkers. Analysis of covariance was used to determine between-group differences. RESULTS Of 150 screened patients, 101 were randomized to the intervention (n = 49) and control (n = 52) groups (mean age: 42.5 ± 14.1 years; M:F 1:3, 48% with ulcerative colitis and 52% with Crohn's disease). The between-group PSS improved by 22.4% (95% confidence interval, 10.5-34.3, p < 0.001). Significant improvements were seen in mental health, resilience, and HRQoL measures, with a median satisfaction score of 89/100 at the end of the 12 weeks. In the 44/49 patients who completed the intervention, 91% achieved program adherence targets. CONCLUSION This 12-week online intervention improved perceived stress, mental health, and HRQoL, but did not impact IBD symptom indices or inflammatory biomarkers. The program was readily adopted and adhered to by participants with high retention rates. After iterative refinement based on participant feedback, future studies will evaluate the impact of a longer/more intense intervention on disease course. REGISTRATION ClinicalTrials.gov Identifier NCT03831750. PLAIN LANGUAGE SUMMARY An online stress reduction intervention in inflammatory bowel disease patients improves stress, mental health, and quality of life People with inflammatory bowel disease (IBD) have high levels of stress, anxiety, and depression. Although IBD patients have expressed the need for online mental wellness interventions, the existing data to support these interventions in IBD are limited. In this trial, 101 IBD patients had the chance to participate in a 12-week online stress reduction intervention. In those patients randomly selected to participate in the online intervention, each week they received the following: a 20- to 30-min yoga, breathwork, and meditation video that they were asked to do 2-3 times a week, a 10- to 20-min mental wellness activity they were asked to do once during the week, and a 10-min telephone check-in with a study team member. Participants who were not selected to use the online intervention received a weekly motivational message by email. In all, 90 of the 101 participants (89%) completed the study with the mean age of participants being 43 years and the majority being females (75%). Ninety-one percent of participants who completed the intervention met the program target of doing the yoga, breathwork, and meditation video at least 2 times per week. Significant improvements were seen in perceived stress (by 22.4%), depression (by 29.5%), anxiety (by 23.7%), resilience (by 10.6%), and quality of life (by 8.9%). No changes were seen in IBD severity or in blood markers of inflammation. In conclusion, this study demonstrates evidence that a 12-week online stress reduction intervention had low dropout rates, high adherence and beneficial effects on stress, mental health, and quality of life measures. Continued feedback will be sought from study participants and our IBD patient partners to refine the intervention and assess the impact in future studies of patients with active IBD, as well as the impact of a longer/more intense intervention.

Abstract
BACKGROUND Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). Patients with inflammatory bowel disease are susceptible to Clostridium difficile infection (CDI). Here, we evaluate CDI in the tofacitinib UC clinical program. METHODS Events from 4 randomized, placebo-controlled studies (phase [P] 2 or P3 induction [NCT00787202; NCT01465763; NCT01458951], P3 maintenance [NCT01458574]) and an open-label, long-term extension (OLE) study (NCT01470612), were analyzed as 3 cohorts: Induction (P2/P3 induction), Maintenance (P3 maintenance), and Overall (patients receiving tofacitinib 5 or 10 mg twice daily [BID] in P2, P3, and OLE studies; including final data from the OLE study, as of August 24, 2020). Proportions and incidence rates (unique patients with events per 100 patient-years of exposure) of CDI were evaluated. RESULTS The overall cohort comprised 1157 patients who received ≥1 dose of tofacitinib 5 or 10 mg BID, with a total of 2814.4 patient-years of tofacitinib exposure and up to 7.8 years of treatment. A total of 82.6% of patients received predominantly tofacitinib 10 mg BID. In the induction, maintenance, and overall cohorts, 3 (2 tofacitinib treated, 1 placebo treated), 3 (all placebo treated), and 9 patients had CDI, respectively; the overall cohort incidence rate was 0.31 (95% confidence interval, 0.14-0.59). CDI were all mild-moderate in severity and resolved with treatment in 8 patients. Six of 9 patients continued tofacitinib treatment without interruption. Two patients had events reported as serious due to hospitalization. Two patients were receiving corticosteroids when the CDI occurred. CONCLUSION CDIs among patients with UC receiving tofacitinib were infrequent, cases were mild-moderate in severity, and most resolved with treatment.

Abstract
Background While no adverse developmental outcomes were observed in preclinical animal studies, limited data exist regarding effects of ustekinumab on human pregnancies. Previously, no data have been reported for women treated with ustekinumab in inflammatory bowel disease (IBD) clinical trials and corresponding pregnancy outcomes. Here, we present pregnancy outcomes from IBD clinical trials, incorporating 5 years of treatment in Crohn's disease (CD) and 2 in ulcerative colitis (UC). Methods All patients in the clinical trials agreed to use adequate birth control and were discontinued from treatment upon pregnancy confirmation. Nonetheless, 39 pregnancies occurred with maternal ustekinumab exposure from 4 CD and 1 UC study. Maternal and neonatal outcomes and data are presented with summary statistics, where available. Results Of 1289 women who received ≥1 dose of ustekinumab, 39 maternal pregnancies with outcomes were reported (pregnancy cohort). Median maternal age was 28.0 years and median duration of ustekinumab treatment before pregnancy was 63.7 weeks with the last dose of ustekinumab administered prior to or during the first trimester (terminal half-life of ~3 weeks). Outcomes for the 39 pregnancies were: 26 live births (all normal newborns), 8 spontaneous abortions, and 5 elective abortions. No congenital anomalies were reported among normal newborns and no safety signals emerged with neonatal outcomes. Conclusions Based on this series of 39 pregnancies with outcomes from IBD clinical trials, mothers treated with ustekinumab (limited to up to the first trimester) did not demonstrate a risk of negative outcomes. More data are needed to characterize the safety profile of ustekinumab use during pregnancy.

Abstract
BACKGROUND Intestinal ultrasound is increasingly used for primary diagnosis, detection of complications and monitoring of patients with Crohn's disease and ulcerative colitis. Standardization of reporting is relevant to ensure quality of the methodology and to improve communication between different specialties. The current manuscript describes the features required for optimized reporting of intestinal ultrasound findings in inflammatory bowel disease (IBD). METHODS An expert consensus panel of gastroenterologists, radiologists, pathologists, paediatric gastroenterologists and surgeons conducted a systematic literature search. In a Delphi- process members of the Kompetenznetz Darmerkrankungen in collaboration with members of the German Society for Radiology (DRG) voted on relevant criteria for reporting of findings in intestinal ultrasound. Based on the voting results statements were agreed by expert consensus. RESULTS Clinically relevant aspects of intestinal ultrasound (IUS) findings have been defined to optimize reporting and to standardize terminology. Minimal requirements for standardized reporting are suggested. The statements focus on description of disease activity as well as on complications of IBD. Attributes of intestinal inflammation are described and illustrated by exemplary images. CONCLUSION The current manuscript provides practical recommendations on how to standardize documentation and reporting from intestinal ultrasound findings in patients with IBD.

Abstract
Endoscopic evaluation to reliably grade disease activity, detect complications including cancer and verification of mucosal healing are paramount in the care of patients with ulcerative colitis (UC); but this evaluation is hampered by substantial intra- and interobserver variability. Recently, artificial intelligence methodologies have been proposed to facilitate more objective, reproducible endoscopic assessment. In a first step, we compared how well several deep learning convolutional neural network architectures (CNNs) applied to a diverse subset of 8000 labeled endoscopic still images derived from HyperKvasir, the largest multi-class image and video dataset from the gastrointestinal tract available today. The HyperKvasir dataset includes 110,079 images and 374 videos and could (1) accurately distinguish UC from non-UC pathologies, and (2) inform the Mayo score of endoscopic disease severity. We grouped 851 UC images labeled with a Mayo score of 0-3, into an inactive/mild (236) and moderate/severe (604) dichotomy. Weights were initialized with ImageNet, and Grid Search was used to identify the best hyperparameters using fivefold cross-validation. The best accuracy (87.50%) and Area Under the Curve (AUC) (0.90) was achieved using the DenseNet121 architecture, compared to 72.02% and 0.50 by predicting the majority class ('no skill' model). Finally, we used Gradient-weighted Class Activation Maps (Grad-CAM) to improve visual interpretation of the model and take an explainable artificial intelligence approach (XAI).

Abstract
BACKGROUND Little is known about the consequences of intrauterine exposure to, and the post-natal clearance of, vedolizumab. AIMS To investigate the levels of vedolizumab in umbilical cord blood of newborns and rates of clearance after birth, as well as how these correlated with maternal drug levels, risk of infection and developmental milestones during the first year of life METHODS: Vedolizumab-treated pregnant women with inflammatory bowel disease were prospectively recruited from 12 hospitals in Denmark and Canada in 2016-2020. Demographics were collected from medical records. Infant developmental milestones were evaluated by the Ages and Stages Questionnaire (ASQ-3). Vedolizumab levels were measured at delivery and, in infants, every third month until clearance. Non-linear regression analysis was applied to estimate clearance. RESULTS In 50 vedolizumab-exposed pregnancies, we observed 43 (86%) live births, seven (14%) miscarriages, no congenital malformations and low risk of adverse pregnancy outcomes. Median infant:mother vedolizumab ratio at birth was 0.44 (95% confidence interval [CI], 0.32-0.56). The mean time to vedolizumab clearance in infants was 3.8 months (95% CI, 3.1-4.4). No infant had detectable levels of vedolizumab at 6 months of age. Developmental milestones at 12 months were normal or above average. Neither vedolizumab exposure in the third trimester (RR 0.54, 95% CI, 0.28-1.03) nor combination therapy with thiopurines (RR 1.29, 95% CI, 0.60-2.77) seemed to increase the risk of infections in the offspring. CONCLUSIONS Neonatal vedolizumab clearance following intrauterine exposure is rapid. Infant vedolizumab levels did not correlate with the risk of infections during the first year of life. Continuation of vedolizumab throughout pregnancy is safe.

Abstract
BACKGROUND AND AIMS While there is recent literature to support the discontinuation of 5-aminosalicylate (5-ASA) upon the initiation of biologics, continuing 5-ASA after treatment failure is relatively common. We aimed to assess the impact of concomitant 5-ASA therapy on clinical outcomes in ulcerative colitis (UC) patients escalated to infliximab. METHODS This is a retrospective chart review of patients with moderate-to-severe UC started on infliximab between January 2012 and December 2017 at the University of Alberta. The primary outcome was clinical remission (partial Mayo score < 2) at 6 and 12 months. Secondary outcomes included endoscopic (endoscopic Mayo < 2) and deep remission (combined clinical and endoscopic remission) as well as the need for rescue therapy, hospitalization or colectomy. Univariate and multivariate logistic regression models were used to estimate the odds ratios and 95% CI for the outcomes. RESULTS One hundred and twenty-one patients were followed over a period of 47 (SD = 34) months. Patients on 5-ASA had increased concomitant immunomodulator use (73.3% vs. 54.1%, p = 0.03). There was no difference in clinical remission at 6 (aOR 2.59, p = 0.07) or 12 months (aOR 0.43, p = 0.06). At 12 months, patients on concomitant 5-ASA were less likely to achieve endoscopic (aOR 0.08, p = 0.01) and deep remission (aOR 0.07, p = 0.02). Adverse outcomes such as need for rescue therapy, hospitalization, and colectomy did not differ between the groups. CONCLUSIONS Our data suggest that 5-ASA may be stopped in patients with moderate-to-severe UC who have been escalated to infliximab therapy as it has no additional benefit to control inflammation.

Abstract
The complete and reliable documentation of endoscopic findings make up the crucial foundation for the treatment of patients with inflammatory bowel diseases such as Crohn´s disease and ulcerative colitis. These findings are, on the one hand, a prerequisite for therapeutic decisions and, on the other hand, important as a tool for assessing the response to ongoing treatments. Endoscopic reports should, therefore, be recorded according to standardized criteria to ensure that the findings of different endoscopists can be adequately compared and that changes in the course of the disease can be traced back. In consideration of these necessities, fifteen members of the Imaging Working Group of the German Kompetenznetz Darmerkrankungen have created a position paper proposing a structure and specifications for the documentation of endoscopic exams. In addition to the formal report structure, the recommendations address a large number of attributes of acute and chronic inflammatory alterations as well as endoscopically detectable complications, which are explained in detail and illustrated using exemplary images. In addition, more frequently used endoscopic activity indices are presented and their use in everyday clinical practice is discussed.

Abstract
BACKGROUND AND AIMS Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis. We report integrated analyses of infections in the Phase [P]2 and P3 OCTAVE programmes. METHODS Three cohorts were analysed: Induction [P2/3 induction studies]; Maintenance [P3 maintenance study]; and Overall [all tofacitinib-treated patients in induction, maintenance, or ongoing, open-label, long-term extension studies; as of May 2019]. Proportions and incidence rates [IRs; unique patients with events/100 patient-years] of serious infections [SIs], herpes zoster [HZ] [non-serious and serious], and opportunistic infections [OIs] are reported [censored at time of event]. RESULTS In the Induction Cohort [N = 1220], no patients receiving placebo and eight [0.9%] receiving tofacitinib 10 mg twice daily [BID] developed SIs. Maintenance Cohort [N = 592] SI IRs (95% confidence interval [CI]) were 1.94 [0.23-7.00] for placebo and 1.35 [0.16-4.87] and 0.64 [0.02-3.54] for tofacitinib 5 and 10 mg BID, respectively; HZ IRs were 0.97 [0.02-5.42], 2.05 [0.42-6.00], and 6.64 [3.19-12.22], respectively. In the Overall Cohort [N = 1157; 82.9% predominantly received tofacitinib 10 mg BID], SI, HZ, and non-HZ OI IRs were 1.70 [1.24-2.27], 3.48 [2.79-4.30], and 0.15 [0.04-0.38], respectively. No SIs resulted in death. CONCLUSIONS During induction, SIs were more frequent with tofacitinib versus placebo. SIs were generally infrequent in the Maintenance and Overall Cohorts, with rates comparable between treatment groups. Maintenance Cohort HZ IR was numerically higher with tofacitinib 10 mg BID versus 5 mg BID. Overall Cohort HZ IRs remained stable over time. Non-HZ OIs and viral infections were rare.

Abstract
The SARS-CoV-2 pandemic has challenged healthcare systems worldwide. Uncertainty of transmission, limitations of physical healthcare system infrastructure and supplies as well as workforce shortages require dynamic adaption of resource deployment to manage rapidly evolving care demands, ideally based on real time data for the entire population. Moreover, shut down of traditional face-to-face care infrastructure requires rapid deployment of virtual health care options to avoid collapse of health organizations. The Alberta Electronic Health Record Information System is one of the largest population based comprehensive electronic medical record (EMR) installations. Alberta's long standing solid telehealth hardware-, training-, provider remuneration- and legislation infrastructure has enabled quick transition to virtual healthcare. Virtual health services including asynchronous secure clinical communications, real-time virtual care via messaging, telephony or video conferencing (telehealth) and ancillary functions like triage, scheduling, documentation and reporting, the previously established virtual hospital program with home monitoring, virtual health assessments, medication review, education and support for patients and families and coordination between family doctors, specialists and other health team members help to control viral transmission, protect healthcare personnel and save supplies. Moreover, rapid launch of online screening and triage tools to guide testing and isolation, online result sharing, infected patient and contact tracing including a smartphone exposure tracking application (ABTraceTogether), electronic best practice alerts and decision support tools, test and treatment order sets for standardized COVID-19 management, continuous access to population level real-time data to inform healthcare provider, public health and government decisions have become key factors in the management of a global crisis in Alberta.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2/COVID-19) pandemic is a worldwide emergency. An increasing number of diarrhea cases is reported. Here we investigate the epidemiology, clinical presentation, molecular mechanisms, management, and prevention of SARS-CoV-2 associated diarrhea. We searched on PubMed, EMBASE, and Web of Science up to March 2020 to identify studies documenting diarrhea and mechanism of intestinal inflammation in patients with confirmed diagnosis of SARS-CoV-2 infection. Clinical studies show an incidence rate of diarrhea ranging from 2% to 50% of cases. It may precede or trail respiratory symptoms. A pooled analysis revealed an overall percentage of diarrhea onset of 10.4%. SARS-CoV uses the angiotensin-converting enzyme 2 (ACE2) and the serine protease TMPRSS2 for S protein priming. ACE2 and TMPRSS2 are not only expressed in lung, but also in the small intestinal epithelia. ACE2 is expressed furthermore in the upper esophagus, liver, and colon. SARS-CoV-2 binding affinity to ACE2 is significantly higher (10-20 times) compared with SARS-CoV. Several reports indicate viral RNA shedding in stool detectable longer time period than in nasopharyngeal swabs. Current treatment is supportive, but several options appear promising and are the subject of investigation. Diarrhea is a frequent presenting symptom in patients infected with SARS-CoV-2. Increasing evidence indicates possible fecal oral transmission, indicating the need for a rapid and effective modification of the screening and diagnostic algorithms. The optimal methods to prevent, manage, and treat diarrhea in COVID-19 infected patients are subjects of intensive research.

Abstract
Computerized clinical decision support systems, or CDSS, represent a paradigm shift in healthcare today. CDSS are used to augment clinicians in their complex decision-making processes. Since their first use in the 1980s, CDSS have seen a rapid evolution. They are now commonly administered through electronic medical records and other computerized clinical workflows, which has been facilitated by increasing global adoption of electronic medical records with advanced capabilities. Despite these advances, there remain unknowns regarding the effect CDSS have on the providers who use them, patient outcomes, and costs. There have been numerous published examples in the past decade(s) of CDSS success stories, but notable setbacks have also shown us that CDSS are not without risks. In this paper, we provide a state-of-the-art overview on the use of clinical decision support systems in medicine, including the different types, current use cases with proven efficacy, common pitfalls, and potential harms. We conclude with evidence-based recommendations for minimizing risk in CDSS design, implementation, evaluation, and maintenance.

Abstract
BACKGROUND Women with inflammatory bowel diseases (IBD) often receive biologicals during pregnancy to maintain disease remission. Data on outcome of vedolizumab-exposed pregnancies (VDZE) are sparse. AIMS To assess pregnancy and child outcomes of VDZE pregnancies and to compare these results to anti-TNF exposed (TNFE) or both immunomodulatory and biologic unexposed (CON IBD) pregnancies. METHODS A retrospective multicentre case-control observational study was performed. RESULTS VDZE group included 79 pregnancies in 73 IBD women. The TNFE and CON IBD group included 186 pregnancies (162 live births) in 164 IBD women and 184 pregnancies (163 live births) in 155 IBD women, respectively. At conception, cases more often had active disease ([VDZE: 36% vs TNFE: 17%, P = .002] and [VDZE: 36% vs CON IBD: 24%, P = .063]). No significant difference in miscarriage rates were found between groups (VDZE and TNFE: 16% vs 13%, P = .567; VDZE and CON IBD: 16% vs 10%, P = .216). In live-born infants, median gestational age and birthweight were similar between groups. Median Apgar score at birth was numerically equal. Prematurity was similar in the VDZE group compared to the control groups, even when correcting for disease activity during pregnancy. The frequency of congenital anomalies was comparable between groups as were the percentages of breastfed babies. During the first year of life, no malignancies were reported and infants' infection risk did not significantly differ between groups. CONCLUSION No new safety signal was detected in VDZE pregnancies although larger, prospective studies are required for confirmation.

Abstract
BACKGROUND & AIMS Colonoscopy requires bowel cleansing for gut mucosa visualization; high-quality cleansing facilitates lesion detection. NER1006 is a 1L polyethylene glycol (PEG) bowel preparation. This post hoc analysis of two randomized trials investigated cleansing efficacy assessed, as in clinical practice, by site endoscopists. METHODS Patients received NER1006, 2L PEG + ascorbate (2LPEG), or oral sulfate solution (OSS) as a 2-day evening/morning regimen (N2D) or NER1006 morning-only dosing (N1D). Treatment-blinded site endoscopists assessed cleansing using the Harefield Cleansing Scale (HCS). Analyses were conducted in a modified full analysis set, including (mFAS; n = 1378) or excluding (mFAS2; n = 1319) imputed failures, and in patients with 100% treatment adherence (mFAS100; n = 1047). Overall cleansing success (HCS grade A/B), overall high-quality cleansing (HCS grade A), and high-quality segments (HCS 3-4) per treatment population were analyzed. RESULTS Overall cleansing success was higher with N2D than 2LPEG (92.7-97.5% vs. 87.9-93.0%), and more patients had overall high-quality cleansing with N2D and N1D than 2LPEG (68.0-72.1% and 64.0-68.4% vs. 50.7-56.0%). Without imputed failures, N2D delivered more overall high-quality cleansing than OSS (74.5-77.3% vs. 67.8-69.8%). More high-quality segments were demonstrated with N2D and N1D versus 2 LPEG (82.5-87.1% and 79.4-84.4% vs. 70.4-76.3%) and with N2D versus OSS (82.7-89.5% vs. 78.1-84.4%). CONCLUSION When assessed by site endoscopists, NER1006 delivers greater high-quality cleansing than 2LPEG or OSS.

Abstract
Inflammatory bowel disease (IBD), namely, Crohn's disease and ulcerative colitis, remains a grievous and recalcitrant problem incurring significant human and health care costs, even in consideration of the growing incidence. Initial goals of care aimed to achieve the induction and maintenance of clinical remission. The advent of novel treat-to-target approaches using patient stratification, early introduction of immunosuppressants and rapid escalation to biologics or early use of combination therapy has refocused the goals of care toward the achievement of mucosal healing. This is in an attempt to preserve intestinal function, decrease hospitalization and surgery rates and improve the quality of life of affected patients. Cellular therapeutics for the treatment of IBD offers an unprecedented opportunity to change the current paradigm from single-targeted to systems-targeted therapy, trying to dampen the whole inflammatory cascade instead of a only molecule. Therefore, as we move forward, the importance of designing informative and possibly adaptive trial designs, standardizing methodologies, harmonizing goals of therapy and evaluating methods cannot be underemphasized. In this article, we review the current literature on the application of mesenchymal stromal cells for the treatment of IBD in an effort to establish a consensus on designing efficient and consistent clinical trials for the intravenous use of this cellular therapy in IBD.

Abstract
BACKGROUND AND AIMS This study examined differences in personality, psychological distress, and stress coping in inflammatory bowel disease (IBD) depending on type of disease and disease activity. We compared patients suffering from Crohn's disease (CD) and ulcerative colitis (UC) with controls. While the literature is replete with distinctive features of the pathogenesis of IBD, the specific differences in psychological impairments are not well studied. METHODS In this German national multicenter study, participants were recruited from 32 centers. Two hundred ninety-seven questionnaires were included, delivering vast information on disease status and psychological well-being based on validated instruments with a total of 285 variables. RESULTS CD patients were more affected by psychological impairments than patients suffering from UC or controls. Importantly, patients with active CD scored higher in neuroticism (p < 0.01), psychological distress (p < 0.001) and maladaptive stress coping (escape, p = 0.03; rumination, p < 0.03), but less need for social support (p = 0.001) than controls. In contrast, patients suffering from active UC showed psychological distress (p < 0.04) and maladaptive coping (avoidance, p < 0.03; escape, p = 0.01). Patients in remission seemed to be less affected. In particular, patients with UC in remission were not inflicted by psychological impairments. The group of CD patients in remission however, showed insecurity (p < 0.01) and paranoid ideation (p = 0.04). CONCLUSIONS We identified specific aspects of psychological impairment in IBD depending on disease and disease activity. Our results underscore the need for psychological support and treatment particularly in active CD.

Abstract
Biological therapies are an effective treatment for a range of immune-mediated inflammatory diseases (IMIDs), including rheumatoid arthritis, psoriasis, and inflammatory bowel diseases. However, due to their high costs, considerable differences in their utilization exist across the world, even among the various European countries, with many countries restricting access despite professional society guideline recommendations. Adoption of biologics by healthcare providers has been particularly poor in many Central and Eastern European countries. Differences in utilization have also been observed across medical specialties, healthcare providers, and at a regional and national level. The objective of this paper is to provide an overview of the different market access policies for biologics in Europe and to investigate reasons for such differences. One of the potential solutions for providing broader access to IMID patients, where cost is the major barrier, is to encourage the use of biosimilars in place of their reference products. Biosimilars are generally less expensive alternatives to already licensed biological therapies and are approved on the basis that they are similar to the reference product in terms of quality, safety, and efficacy. Budget impact models predict considerable cost savings following the introduction of biosimilars in the next few years. These savings could be used to increase access to biologics and other innovative therapies.

Abstract
BACKGROUND Polyethylene glycol (PEG) bowel preparations are widely used for precolonoscopy bowel cleansing. This phase 3 trial assessed the efficacy, safety, and tolerability of the novel 1 L PEG-based NER1006 vs. sodium picosulfate plus magnesium citrate (SP + MC) in day-before dosing. METHODS Patients requiring colonoscopy were randomized (1 : 1) to receive NER1006 or SP + MC. Cleansing was assessed on the Harefield Cleansing Scale (HCS) and Boston Bowel Preparation Scale (BBPS) using central readers. Two primary end points were assessed: overall colon cleansing success and high-quality cleansing of the right colon. Intention-to-treat (modified full analysis set [mFAS]) and per protocol (PP) analyses were performed. RESULTS Of 515 patients, efficacy was analyzed in 501 (NER1006, n = 250; SP + MC, n = 251) and 379 patients (NER1006, n = 172; SP + MC, n = 207) in the mFAS and PP analyses, respectively. Non-inferiority of NER1006 vs. SP + MC was established in the mFAS for both overall cleansing (62.0 % vs. 53.8 %; P = 0.04) and high-quality cleansing in the right colon (4.4 % vs. 1.2 %; P = 0.03). Superiority of NER1006 was demonstrated using HCS in the PP set for overall cleansing success (68.0 % vs. 57.5 %; P = 0.02) and right colon high-quality cleansing (5.2 % vs. 1.0 %; P = 0.02) and using BBPS in the mFAS for overall cleansing success (58.4 % vs. 45.8 %; P = 0.003) and right colon high-quality cleansing (4.0 % vs. 0.8 %; P = 0.02). Mean segmental scores for 4/5 segments were higher with NER1006 (P ≤ 0.04). Both treatments were well tolerated, with more mild adverse events for NER1006 (17.0 % vs. 10.0 %; P = 0.03). CONCLUSIONS Colon cleansing with NER1006 vs. SP + MC was non-inferior (mFAS) and superior (PP), with acceptable safety.European Clinical Trials Database (EudraCT)2014-002186-30TRIAL REGISTRATION: Multicenter, randomized, parallel group, phase 3 study 2014-002186-30 at https://eudract.ema.europa.eu/.

Abstract
BACKGROUND Active inflammatory bowel disease increases the risk of adverse pregnancy outcomes. Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). As a small molecule, tofacitinib is likely to cross the placental barrier; however, information on the effects of tofacitinib on pregnancy outcomes is limited. We report pregnancy and newborn outcomes among patients in UC clinical studies with prenatal (maternal/paternal) exposure to tofacitinib. METHODS Pregnancies with maternal/paternal exposure to tofacitinib were identified and outcomes reported in 5 tofacitinib UC interventional studies (up to March 2017). Outcomes from tofacitinib rheumatoid arthritis (RA), psoriasis, and psoriatic arthritis interventional studies, and RA noninterventional postapproval safety studies, spontaneous adverse event reporting, and registry data are also reported. RESULTS Of 1157 patients enrolled in the UC interventional studies, 301 were women of childbearing age. Eleven cases of maternal exposure and 14 cases of paternal exposure to tofacitinib (doses of 5 mg or 10 mg twice daily) before/at the time of conception or during pregnancy were identified. Outcomes included 15 healthy newborns, no fetal deaths, no neonatal deaths, no congenital malformations, 2 spontaneous abortions, and 2 medical terminations. Outcomes across other tofacitinib studies and postmarketing cases were consistent, with a healthy newborn being the most common outcome and no fetal deaths. CONCLUSIONS Based on the limited data available, pregnancy and newborn outcomes among patients with prenatal (maternal/paternal) exposure to tofacitinib in UC studies appear similar to those reported for other tofacitinib clinical study populations and the general population.

Abstract
BACKGROUND Vedolizumab (VDZ) is effective for treatment of ulcerative colitis (UC) and Crohn's disease (CD). In GEMINI trials, anti-tumor necrosis factor (anti-TNF)-naïve patients had a superior response compared with anti-TNF-exposed patients. In real-world experience (RWE), the number of included anti-TNF-naïve patients was low. We aimed to evaluate the effectiveness and safety of VDZ in anti-TNF-naïve patients in an RWE setting. METHODS This retrospective multicenter European pooled cohort study included consecutive active anti-TNF-naïve IBD patients treated with VDZ. The primary end point was clinical response at week 14. Patients with follow-up beyond week 14 and those discontinuing VDZ at any time were included for maintenance outcomes analysis. RESULTS Since January 2015, 184 anti-TNF-naïve patients from 23 centers initiated VDZ treatment (Crohn's disease [CD], 50; ulcerative colitis [UC], 134). In CD, 42/50 (82%) patients responded by week 14 and 32 (64%) were in clinical remission; 26/50 (52%) achieved corticosteroid-free remission (CSFR). At last follow-up (44 weeks; interquartile range [IQR], 30-52 weeks), 27/35 (77.1%) patients with available data responded to treatment; 24/35 (68.6%) were in clinical remission, 21/35 (60%) were in CSFR. For UC, 116/134 (79.1%) responded to treatment by week 14, including 53 (39.5%) in clinical remission; 49/134 (36.6%) achieved CSFR. At last follow-up (42.5 weeks; IQR, 30-52 weeks), 79/103 (76.7%) patients responded to treatment, 69/103 (67.0%) were in remission, and 61/103 (59.2%) were in CSFR. Adverse effects were reported in 20 (11%) of the patients, leading to treatment discontinuation in 6 (3.3%). CONCLUSIONS VDZ is similarly effective in ant-TNF-naïve CD and UC patients. The efficacy is higher than reported in anti-TNF-experienced patients and is comparable to that of anti-TNF biologics in this population.

Abstract
Introduction: Zymogen granule glycoprotein 2 (GP2) was demonstrated as first autoimmune mucosal target in primary sclerosing cholangitis (PSC) associated with disease severity. Autoantibodies to four GP2 isoforms (aGP21-4) were found in patients with inflammatory bowel diseases but reactivity against specific GP2 epitopes has not been investigated in PSC yet. Hence, the prevalence of aGP21-4 and their association with the PSC phenotype for risk prediction were examined. Methods: GP2 isoforms were stably expressed as glycosylphosphatidyl - inositol-anchored molecules in the membrane of HEp-2 cells and used as autoantigenic targets in indirect immunofluorescence assay (IFA). aGP21-4 IgA and IgG were detected by IFA in 212 PSC patients of four European university hospitals and 145 controls comprising 95 patients with cystic fibrosis and 50 healthy subjects. Results: Combined aGP21 and aGP24 IgA testing with a sensitivity of 66.0% and a specificity of 97.9% resulted in the best diagnostic performance (Youden index: 0.64) regarding all aGP2 and combinations thereof. aGP24 IgA positivity is significantly associated with the presence of cirrhosis in PSC (p = 0.0056). Logistic regression revealed the occurrence of aGP21 IgA (odds ratio [OR] 1.38, 95% confidence interval [CI]: 1.03-1.86) and aGP24 IgA (OR 1.52, 95%CI: 1.07-2.15) along with male gender (OR 0.51, 95%CI: 0.27-0.97) and older age (OR 1.03 95%CI: 1.01-1.05) as significant risks for the concomitant presence of cirrhosis in PSC. Conclusions: Combined aGP21 and aGP24 IgA analysis is preferred to single aGP2 isoform analysis for sensitive PSC autoantibody testing. Positivity for aGP21 and aGP24 IgA is associated with cirrhosis in PSC and could be used for risk stratification.

Abstract
OBJECTIVES To establish clinical consensus on important and relevant quality-of-care (QoC) attributes in ulcerative colitis (UC) treatment that may improve treatment outcomes and guide best practices. METHODS Thirty-eight QoC attributes were identified in a literature review. Sixteen European-based experts were selected based on their contributions to UC guidelines, publications, and patient care. A 3-round, modified Delphi panel was conducted including an interview round, and 2 web-based rounds to reach consensus and finalize a QoC attribute list. RESULTS The draft QoC attribute list derived from a literature review and Round 1, expert interviews, comprised 63 attributes. In Rounds 2 and 3, the QoC attributes frequently rated as critically important were diagnosis (n = 15, 93.8%), treatment adherence (n = 15, 93.8%), and access to care/treatment (Round 2: n = 14, 87.5%; Round 3: n = 15, 93.8%). The final QoC attribute list consisted of 61 attributes across 20 domains, with the most attributes reported in the "treatment goals" domain (n = 9). CONCLUSION QoC is a complex and evolving concept that can improve outcomes while maximizing healthcare resources. Limited time and resources hamper clinicians' ability to openly and empathetically communicate with patients; novel technology may help to offer solutions.

Abstract
OBJECTIVES Current options for patients with steroid-dependent, chronic-active ulcerative colitis (UC) with insufficient response/intolerance to immunosuppressants (ISs) and/or biologics are limited. The aim of this study was to assess the long-term outcome of granulocyte/monocyte adsorptive (GMA) apheresis (Adacolumn®) in this population. MATERIALS AND METHODS Ninety five adults with steroid-dependent active UC and insufficient response/intolerance to IS and/or TNF inhibitors received 5-8 aphereses in a single induction series of ≤10 weeks. Endpoints included rates of remission (clinical activity index [CAI] ≤ 4) at weeks 24 and 48. RESULTS Of 94 patients (ITT population), remission and response rates were 34.0% and 44.7% at week 24, and 33.0% and 39.4% at week 48. Among 30 patients with prior failure of IS and biologics, 33.3% and 20.0% were in remission at weeks 24 and 48. At both weeks, 19.2% of patients achieved steroid-free remission. Sustained remission or response occurred in 27.7% of patients at 48 weeks. The cumulative colectomy rate at week 96 was 23.4%. Safety was consistent with previous findings. CONCLUSIONS This study confirms findings of the 12-week interim analysis and demonstrates that GMA apheresis provides a safe and beneficial long-term outcome for patients with chronic active UC resistant/intolerant to IS and/or TNF inhibitors.

Abstract
BACKGROUND & AIMS Therapies for perianal fistulas in patients with Crohn's disease are often ineffective in producing long-term healing. We performed a randomized placebo-controlled trial to determine the long-term efficacy and safety of a single local administration of allogeneic expanded adipose-derived stem cells (Cx601) in patients with Crohn's disease and perianal fistulas. METHODS We performed a double-blind study at 49 hospitals in Europe and Israel, comprising 212 patients with Crohn's disease and treatment-refractory, draining, complex perianal fistulas. Patients were randomly assigned (1:1) to groups given a single local injection of 120 million Cx601 cells or placebo (control), in addition to the standard of care. Efficacy endpoints evaluated in the modified intention-to-treat population (randomly assigned, treated, and with 1 or more post-baseline efficacy assessment) at week 52 included combined remission (closure of all treated external openings draining at baseline with absence of collections >2 cm, confirmed by magnetic resonance imaging) and clinical remission (absence of draining fistulas). RESULTS The study's primary endpoint, at week 24, was previously reported (combined remission in 51.5% of patients given Cx601 vs 35.6% of controls, for a difference of 15.8 percentage points; 97.5% confidence interval [CI] 0.5-31.2; P = .021). At week 52, a significantly greater proportion of patients given Cx601 achieved combined remission (56.3%) vs controls (38.6%) (a difference of 17.7 percentage points; 95% CI 4.2-31.2; P = .010), and clinical remission (59.2% vs 41.6% of controls, for a difference of 17.6 percentage points; 95% CI 4.1-31.1; P = .013). Safety was maintained throughout week 52; adverse events occurred in 76.7% of patients in the Cx601 group and 72.5% of patients in the control group. CONCLUSION In a phase 3 trial of patients with Crohn's disease and treatment-refractory complex perianal fistulas, we found Cx601 to be safe and effective in closing external openings, compared with placebo, after 1 year.

Abstract
Background Iron-deficiency anemia and iron deficiency are common comorbidities associated with inflammatory bowel disease (IBD) resulting in impaired quality of life and high health care costs. Intravenous iron has shown clinical benefit compared to oral iron therapy. Aim This study aimed to compare health care outcomes and costs after oral vs intravenous iron treatment for IBD patients with iron deficiency or iron deficiency anemia (ID/A) in Germany. Methods IBD patients with ID/A were identified by ICD-10-GM codes and newly commenced iron treatment via ATC codes in 2013 within the InGef (formerly Health Risk Institute) research claims database. Propensity score matching was performed to balance both treatment groups. Non-observable covariates were adjusted by applying the difference-in-differences (DID) approach. Results In 2013, 589 IBD patients with ID/A began oral and 442 intravenous iron treatment. After matching, 380 patients in each treatment group were analyzed. The intravenous group had fewer all-cause hospitalizations (37% vs 48%) and ID/A-related hospitalizations (5% vs 14%) than the oral iron group. The 1-year preobservation period comparison revealed significant health care cost differences between both groups. After adjusting for cost differences by DID method, total health care cost savings in the intravenous iron group were calculated to be €367. While higher expenditure for medication (€1,876) was observed in the intravenous iron group, the inpatient setting achieved most cost savings (€1,887). Conclusion IBD patients receiving intravenous iron were less frequently hospitalized and incurred lower total health care costs compared to patients receiving oral iron. Higher expenditures for pharmaceuticals were compensated by cost savings in other domains.

Abstract
BACKGROUND AND AIMS Progressive multifocal leukoencephalopathy [PML], a brain infection associated with anti-integrin drugs that inhibit lymphocyte translocation from bloodstream to tissue, can be fatal. Decreased central nervous system [CNS] immune surveillance leading to this infection has been reported in patients with multiple sclerosis or Crohn's disease treated with anti-integrin antibody natalizumab. PF-00547659 is an investigational human monoclonal antibody for inflammatory bowel disease, targeted against α4β7-mucosal addressin cell-adhesion molecule-1 [the integrin ligand selectively expressed in the gut]. We hypothesised that this selective agent would not affect central nervous system immune surveillance. METHODS Cerebrospinal fluid from five healthy volunteers, and from 10 patients with Crohn's disease previously treated with immunosuppressants, was evaluated to assess the feasibility of the study. Subsequently, 39 patients with active Crohn's disease and previous immunosuppression were evaluated over 12 weeks of PF-00547659-induction therapy. We measured total lymphocytes, T cell subsets in cerebrospinal fluid, and circulating β7+ memory cells. Disease activity was assessed using the Harvey-Bradshaw Index. RESULTS Patients treated with PF-00547659 had no reduction of cerebrospinal fluid lymphocytes, T-lymphocyte subsets, or CD4:CD8 ratio, whereas circulating β7+ memory cells increased significantly. A total of 28/35 [80%] patients had a clinical response and 27/34 [79%] had disease remission. Treatment-related adverse events, none serious, were reported in 23/49 [47%] patients. CONCLUSIONS In patients with active Crohn's disease, natalizumab therapy increases the risk for PML, and the increased risk is thought to be associated with iatrogenic leukopenia within the CNS. PML under PF-00547659 may be a lesser concern, as this agent did not reduce lymphocytes or T cell subsets in the cerebrospinal fluid.

Abstract
AIM The aim of this study was to investigate the influence of immunosuppression following orthotopic liver transplantation (OLT) on course of inflammatory bowel disease (IBD) including disease activity and complications. METHODS Out of 1168 patients undergoing liver transplantation between 1988 and 2000 at our center, we identified those with IBD (n = 67). In a comparative cohort study, IBD patients after OLT were compared to controls without OLT. All drugs including immunosuppressive and anti-inflammatory medication and complications during follow-up were recorded in 6-month intervals. Also, surgical interventions before and after OLT as well as endoscopic interventions with macroscopic and microscopic findings were collected and analyzed. Additionally, development of malignant neoplasias was recorded. RESULTS Of the 67 individuals with IBD and OLT, 41 were available for analyses and compared with 42 controls. The mean follow-up was 7.4 (range: 3 - 15) years. Short-term therapy with calcineurin inhibitors or mycophenolate mofetil led to short-term remission, yet sustained remission could only be achieved in patients receiving mycophenolate mofetil. At 14.5 years, clinical remission was reached by significantly more patients in the transplant group (54 %) than in the control group (33 %, p = 0.0295). Patients in the control group required nearly 2 times as many surgical interventions related to IBD than patients in the transplant group. Neoplasias were more common in the OLT (n = 8) compared with 4 solid organ cancers in the control group, respectively. CONCLUSIONS Our data demonstrate an overall positive impact of immunosuppression following OLT on the course of IBD, especially with mycophenolate mofetil, but an increased rate of malignancies.

Abstract
Background Traditional teaching concepts in medical education do not take full advantage of current information technology. We aimed to objectively determine the impact of Tablet PC enhanced training on learning experience and MKSAP® (medical knowledge self-assessment program) exam performance. Methods In this single center, prospective, controlled study final year medical students and medical residents doing an inpatient service rotation were alternatingly assigned to either the active test (Tablet PC with custom multimedia education software package) or traditional education (control) group, respectively. All completed an extensive questionnaire to collect their socio-demographic data, evaluate educational status, computer affinity and skills, problem solving, eLearning knowledge and self-rated medical knowledge. Both groups were MKSAP® tested at the beginning and the end of their rotation. The MKSAP® score at the final exam was the primary endpoint. Results Data of 55 (tablet n = 24, controls n = 31) male 36.4%, median age 28 years, 65.5% students, were evaluable. The mean MKSAP® score improved in the tablet PC (score Δ + 8 SD: 11), but not the control group (score Δ- 7, SD: 11), respectively. After adjustment for baseline score and confounders the Tablet PC group showed on average 11% better MKSAP® test results compared to the control group (p<0.001). The most commonly used resources for medical problem solving were journal articles looked up on PubMed or Google®, and books. Conclusions Our study provides evidence, that tablet computer based integrated training and clinical practice enhances medical education and exam performance. Larger, multicenter trials are required to independently validate our data.

Abstract
In the past decade the gut microbiome has received scientific attention like few other topics. It has become increasingly apparent that the commensal microbiota plays an important role in maintaining the health of the host. Changes of the microbiota composition or function coincide with different disorders such as infectious (i. e. Clostridium difficile infection) or inflammatory bowel diseases like Crohn's disease or ulcerative colitis. Although the significance of this observation has not yet been fully elucidated and understood, several of attempts aimed at modulating the microbiota composition have been made. This article gives an update on current advances and clinical implications of the gut microbiome in infectious and inflammatory bowel diseases.

Abstract
BACKGROUND Vedolizumab, a monoclonal antibody targeting the α4β7-integrin, is effective in inducing and maintaining clinical remission in Crohn's disease and ulcerative colitis according to randomised clinical trials. AIM To determine the long-term effectiveness of vedolizumab in a real-world clinical setting. METHODS This observational registry assessed the clinical outcome in patients treated with vedolizumab for clinically active Crohn's disease (n = 67) or ulcerative colitis (n = 60). Primary endpoint was clinical remission (HBI ≤ 4/pMayo ≤ 1) at week 54. Secondary endpoints included clinical response rates (HBI/pMayo score drop ≥3) and steroid-free clinical remission at weeks 30 and 54. RESULTS Vedolizumab was stopped in 69/127 (56%) patients after a median time of 18 weeks (range 2-49) predominantly owing to lack or loss of response. Using nonresponder imputation analysis, clinical remission and steroid-free remission rates were 21% and 15% in Crohn's disease and 25% and 22% in ulcerative colitis, respectively. Lack of clinical remission was associated with prior treatment with anti-TNF or with steroids for more than 3 months in the last 6 months in ulcerative colitis. At week 14, the absence of remission in Crohn's disease or nonresponse in ulcerative colitis indicated a low likelihood of clinical remission at week 54 [2/31 (7%) in Crohn's disease, 4/41 (10%) in ulcerative colitis]. Accordingly, declining C-reactive protein in inflammatory bowel disease and/or lower faecal calprotectin in ulcerative colitis at week 14 predicted remission at week 54. CONCLUSION Among patients who started vedolizumab for active inflammatory bowel disease, clinical remission rates are 21-25% after 54 weeks.

Abstract
BACKGROUND Complex perianal fistulas in Crohn's disease are challenging to treat. Allogeneic, expanded, adipose-derived stem cells (Cx601) are a promising new therapeutic approach. We aimed to assess the safety and efficacy of Cx601 for treatment-refractory complex perianal fistulas in patients with Crohn's disease. METHODS We did this randomised, double-blind, parallel-group, placebo-controlled study at 49 hospitals in seven European countries and Israel from July 6, 2012, to July 27, 2015. Adult patients (≥18 years) with Crohn's disease and treatment-refractory, draining complex perianal fistulas were randomly assigned (1:1) using a pre-established randomisation list to a single intralesional injection of 120 million Cx601 cells or 24 mL saline solution (placebo), with stratification according to concomitant baseline treatment. Treatment was administered by an unmasked surgeon, with a masked gastroenterologist and radiologist assessing the therapeutic effect. The primary endpoint was combined remission at week 24 (ie, clinical assessment of closure of all treated external openings that were draining at baseline, and absence of collections >2 cm of the treated perianal fistulas confirmed by masked central MRI). Efficacy was assessed in the intention-to-treat (ITT) and modified ITT populations; safety was assessed in the safety population. This study is registered with ClinicalTrials.gov, number NCT01541579. FINDINGS 212 patients were randomly assigned: 107 to Cx601 and 105 to placebo. A significantly greater proportion of patients treated with Cx601 versus placebo achieved combined remission in the ITT (53 of 107 [50%] vs 36 of 105 [34%]; difference 15·2%, 97·5% CI 0·2-30·3; p=0·024) and modified ITT populations (53 of 103 [51%] vs 36 of 101 [36%]; 15·8%, 0·5-31·2; p=0·021). 18 (17%) of 103 patients in the Cx601 group versus 30 (29%) of 103 in the placebo group experienced treatment-related adverse events, the most common of which were anal abscess (six in the Cx601 group vs nine in the placebo group) and proctalgia (five vs nine). INTERPRETATION Cx601 is an effective and safe treatment for complex perianal fistulas in patients with Crohn's disease who did not respond to conventional or biological treatments, or both.

Abstract
BACKGROUND AND AIMS Patients with active, steroid-dependent ulcerative colitis with insufficient response or intolerance to immunosuppressants and/or biologic therapies have limited treatment options. Adacolumn, a granulocyte/monocyte adsorptive apheresis device, has shown clinical benefit in these patients. This study aimed to provide additional clinical data regarding the safety and efficacy of Adacolumn in this patient subgroup. METHODS This single-arm, open-label, multicentre trial [ART] was conducted at 18 centres across the UK, France, and Germany. Eligible patients were 18-75 years old with moderate-to-severe, steroid-dependent active ulcerative colitis with insufficient response or intolerance to immunosuppressants and/or biologics. Patients received ≥ 5 weekly apheresis sessions with Adacolumn. The primary endpoint was clinical remission rate [clinical activity index ≤ 4] at Week 12. RESULTS In all, 86 patients were enrolled. At Week 12, 33/84 [39.3%] of patients in the intention-to-treat population achieved clinical remission, with 47/84 [56.0%] achieving a clinical response [clinical activity index reduction of ≥ 3]. Clinical remission was achieved in 30.0% of patients with previous immunosuppressant and biologic failure; steroid-free clinical remission and response were observed in 22.6% and 35.7% of these patients, respectively. Quality of life [Short Health Scale] significantly improved at Week 12 [p < 0.0001]. The majority of adverse events were of mild/moderate intensity. CONCLUSIONS At Week 12, Adacolumn provided significant clinical benefit in a large cohort of steroid-dependent ulcerative colitis patients with previous failure to immunosuppressant and/or biologic treatment, with a favourable safety profile. These results are consistent with previous studies and support Adacolumn use in this difficult-to-treat patient subgroup.

Abstract
BACKGROUND Vedolizumab (VDZ) is a humanised monoclonal IgG1 antibody targeting α4 β7 integrin. AIM To investigate the real-world efficacy of vedolizumab for the treatment of Crohn's disease (CD) and ulcerative colitis (UC). METHODS A consecutive cohort of 212 adult IBD patients with active disease (HBI >7/partial Mayo >4) newly receiving VDZ was prospectively recruited from 7 academic and 17 community centres. The primary endpoint was clinical remission (CRM) (CD HBI ≤4, UC pMayo ≤1) in week 14. Secondary endpoints included steroid-free remission (SFCRM), clinical response (CRS) (HBI/pMayo score drop ≥3), vedolizumab impact on CRP, calprotectin and haemoglobin. RESULTS Data of 97 CD (71.1% female, HBI 11) and 115 UC (42.6% female, pMayo 6) patients were analysed. Only 5.2% CD and 24.3% UC were anti-TNFα naïve. Most had extensive mucosal involvement (Montreal L3 69.1%/E3 53.9%). At week 14, 23.7% vs. 23.5% of CD vs. UC patients achieved CRM, 19.6% vs. 19.1% SFCRM and 60.8% vs. 57.4% CRS, respectively (all based on NRI). Week 14 CRM in CD was significantly associated with no history of extraintestinal manifestations (P = 0.019), no prior adalimumab use (P = 0.011), no hospitalisation in the past 12 months (P = 0.015) and low HBI score (P = 0.02) and in UC with active or previous smoking (P = 0.044/0.028) and no anti-TNFα (P = 0.023) use. Low HBI (P = 0.019) and no hospitalisation in the past 12 months (P = 0.01) predict CD CRM. The three most common AE were joint pain, acne and nasopharyngitis. CONCLUSION Vedolizumab is effective in routine use.
