Abstract
PURPOSE Team management strategies for complex colorectal polyps are recommended by professional guidelines. Multi-disciplinary meetings are used across the UK with limited information regarding their impact. The aim of this multi-centre observational study was to assess procedures and outcomes of patients managed using these approaches. METHOD This was a retrospective, observational study of patients managed by six UK sites. Information was collected regarding procedures and outcomes including length of stay, adverse events, readmissions and cancers. RESULTS Two thousand one hundred ninety-two complex polyps in 2109 patients were analysed with increasing referrals annually. Most presented symptomatically and the mean polyp size was 32.1 mm. Primary interventions included endoscopic therapy (75.6%), conservative management (8.3%), colonic resection (8.1%), trans-anal surgery (6.8%) or combined procedures (1.1%). The number of primary colonic resections decreased over the study period without a reciprocal increase in secondary procedures or recurrence. Secondary procedures were required in 7.8%. The median length of stay for endoscopic procedures was 0 days with 77.5% completed as day cases. Median length of stay was 5 days for colonic resections. Overall adverse event and 30-day readmission rates were 9.0% and 3.3% respectively. Malignancy was identified in 8.8%. Benign polyp recurrence occurred in 13.1% with a median follow up of 30.4 months. Screening detected lesions were more likely to undergo bowel resection. Colonic resection was associated with longer stays, higher adverse events and more cancers on final histology. CONCLUSION Multi-disciplinary team management of complex polyps is safe and effective. Standardisation of organisation and quality monitoring is needed to continue positive effects on outcomes and services.

Abstract
ObjectiveThe aim of this survey was to understand the impact of the COVID-19 pandemic and recovery phase on workload, well-being and workforce attrition in UK gastroenterology and hepatology.Design/methodA cross-sectional survey of British Society of Gastroenterology physician and trainee members was conducted between August and October 2021. Multivariable binary logistic regression and qualitative analyses were performed.ResultsThe response rate was 28.8% (180/624 of opened email invites). 38.2% (n=21/55) of those who contracted COVID-19 felt pressured to return to work before they felt ready. 43.8% (71/162) had a regular increase in out-of-hours working. This disproportionately affected newly appointed consultants (OR 5.8), those working full-time (OR 11.6), those who developed COVID-19 (OR 4.1) and those planning early retirement (OR 4.0). 92% (150/164) believe the workforce is inadequate to manage the service backlog with new consultants expressing the highest levels of anxiety over this. 49.1% (80/163) felt isolated due to remote working and 65.9% (108/164) felt reduced face-to-face patient contact made their job less fulfilling. 34.0% (55/162) planned to work more flexibly and 54.3% (75/138) of consultants planned to retire early in the aftermath of the pandemic. Early retirement was independently associated with male gender (OR 2.5), feeling isolated from the department (OR 2.3) and increased anxiety over service backlog (OR 1.02).ConclusionThe pandemic has placed an additional burden on work-life balance, well-being and workforce retention within gastroenterology and hepatology. Increased aspirations for early retirement and flexible working need to be explicitly addressed in future workforce planning.

Abstract
BACKGROUND Anti-drug antibodies are associated with treatment failure to anti-TNF agents in patients with inflammatory bowel disease (IBD). AIM To assess whether immunogenicity to a patient's first anti-TNF agent would be associated with immunogenicity to the second, irrespective of drug sequence METHODS: We conducted a UK-wide, multicentre, retrospective cohort study to report rates of immunogenicity and treatment failure of second anti-TNF therapies in 1058 patients with IBD who underwent therapeutic drug monitoring for both infliximab and adalimumab. The primary outcome was immunogenicity to the second anti-TNF agent, defined at any timepoint as an anti-TNF antibody concentration ≥9 AU/ml for infliximab and ≥6 AU/ml for adalimumab. RESULTS In patients treated with infliximab and then adalimumab, those who developed antibodies to infliximab were more likely to develop antibodies to adalimumab, than patients who did not develop antibodies to infliximab (OR 1.99, 95%CI 1.27-3.20, p = 0.002). Similarly, in patients treated with adalimumab and then infliximab, immunogenicity to adalimumab was associated with subsequent immunogenicity to infliximab (OR 2.63, 95%CI 1.46-4.80, p < 0.001). For each 10-fold increase in anti-infliximab and anti-adalimumab antibody concentration, the odds of subsequently developing antibodies to adalimumab and infliximab increased by 1.73 (95% CI 1.38-2.17, p < 0.001) and 1.99 (95%CI 1.34-2.99, p < 0.001), respectively. Patients who developed immunogenicity with undetectable drug levels to infliximab were more likely to develop immunogenicity with undetectable drug levels to adalimumab (OR 2.37, 95% CI 1.39-4.19, p < 0.001). Commencing an immunomodulator at the time of switching to the second anti-TNF was associated with improved drug persistence in patients with immunogenic, but not pharmacodynamic failure. CONCLUSION Irrespective of drug sequence, immunogenicity to the first anti-TNF agent was associated with immunogenicity to the second, which was mitigated by the introduction of an immunomodulator in patients with immunogenic, but not pharmacodynamic treatment failure.

Abstract
Medical endoscopy trainees face numerous, often conflicting demands on their time. This can result in suboptimal endoscopy training and in difficulty achieving certification in basic endoscopy within the existing 5-year training programme. Endoscopic management of acute gastrointestinal bleeding and basic polypectomy are integral to basic service provision. Competence in these and other therapeutic procedures, including dealing with complications, is currently acquired opportunistically, or through experiential independent practice. This article proposes several potential solutions that may help with endotherapy training in the current UK training programmes. It also addresses issues relating to speciality training when reduced to 4 years in 2022. Advanced endotherapy training needs to be optimised by understanding how to select individuals with the appropriate skills and how to accelerate therapeutic training at the appropriate time. Training programmes will need to adapt and can learn from countries where the pathway is more developed and established. Future training will include a dedicated subspeciality training programme for advanced therapy with competitive entry. Advanced therapy training will be matched to service needs. Scoring systems for case complexity integrated with regional and supraregional networks, would allow referral of selected cases to the most appropriate specialised units.

Abstract
In the UK, gastroenterology has been a male predominant medical speciality. Data regarding gender within workforce, academia and leadership at a national level are lacking. Data regarding scholarly presentation at the following annual conferences were collected and analysed; British Society of Gastroenterology (BSG) 2013, 2014, and Digestive Diseases Federation (DDF) in 2015. Data from the 2013-2015 BSG annual workforce reports were examined. In 2015, female higher specialty trainees (STs) made up 39% (328/848) of the trainee workforce, versus 37% and 35% in 2014 and 2013. From 2013 to 2015, less than a fifth of all consultant gastroenterologists were women. Female consultant (18%), ST (39%), associate (86%) and student attendance (47%) at DDF 2015 did not change significantly from 2013 to 2014. Female speakers (trainees and consultants) were significantly lower at DDF 2015 compared with BSG 2014; 43/331 (13%) versus 56/212 (26.4%) (p=0.0001) and BSG 2013 63/231 (27%) (p=0.0001). The number of female chairs, delivery of the named lectures and prizes awarded to women did not differ across the 3-year period. Female leadership via representation at Council and Executive at BSG was 4/30 (13%) in 2015 and did not differ in 2013/2014, with no elected council members since 2008 and one female president in 1973. The proportion of female gastroenterology trainees and consultants is increasing, but remains lower than across all medical specialties and is reflected in attendance and scholarly contributions. Action within the BSG is underway to address female under-representation in leadership roles.

Abstract
BACKGROUND Improvements in the structure of endoscopy training programmes resulting in certification from the Joint Advisory Group in Gastrointestinal Endoscopy have been acknowledged to improve training experience and contribute to enhanced colonoscopy performance. OBJECTIVES The 2016 British Society of Gastroenterology trainees' survey of endoscopy training explored the delivery of endoscopy training - access to lists; level of supervision and trainee's progression through diagnostic, core therapy and subspecialty training. In addition, the barriers to endoscopy training progress and utility of training tools were examined. METHODS A web-based survey (Survey Monkey) was sent to all higher specialty gastroenterology trainees. RESULTS There were some improvements in relation to earlier surveys; 85% of trainees were satisfied with the level of supervision of their training. But there were ongoing problems; 12.5% of trainees had no access to a regular training list, and 53% of final year trainees had yet to achieve full certification in colonoscopy. 9% of final year trainees did not feel confident in endoscopic management of upper GI bleeds. CONCLUSIONS The survey findings provide a challenge to those agencies tasked with supporting endoscopy training in the UK. Acknowledging the findings of the survey, the paper provides a strategic response with reference to increased service pressures, reduced overall training time in specialty training programmes and the requirement to support general medical and surgical on-call commitments. It describes the steps required to improve training on the ground: delivering additional training tools and learning resources, and introducing certification standards for therapeutic modalities in parallel with goals for improving the quality of endoscopy in the UK.

Abstract
BACKGROUND AND AIMS Nephrotoxicity is a rare idiosyncratic reaction to 5-aminosalicylate (5-ASA) therapies. The aims of this study were to describe the clinical features of this complication and identify clinically useful genetic markers so that these drugs can be avoided or so that monitoring can be intensified in high-risk patients. METHODS Inflammatory bowel disease patients were recruited from 89 sites around the world. Inclusion criteria included normal renal function prior to commencing 5-ASA, ≥50% rise in creatinine any time after starting 5-ASA, and physician opinion implicating 5-ASA strong enough to justify drug withdrawal. An adjudication panel identified definite and probable cases from structured case report forms. A genome-wide association study was then undertaken with these cases and 4109 disease controls. RESULTS After adjudication, 151 cases of 5-ASA-induced nephrotoxicity were identified. Sixty-eight percent of cases were males, with nephrotoxicity occurring at a median age of 39.4 years (range 6-79 years). The median time for development of renal injury after commencing 5-ASA was 3.0 years (95% confidence interval [CI] 2.3-3.7). Only 30% of cases recovered completely after drug withdrawal, with 15 patients requiring permanent renal replacement therapy. A genome-wide association study identified a suggestive association in the HLA region (p = 1×10(-7)) with 5-ASA-induced nephrotoxicity. A sub-group analysis of patients who had a renal biopsy demonstrating interstitial nephritis (n = 55) significantly strengthened this association (p = 4×10(-9), odds ratio 3.1). CONCLUSIONS This is the largest and most detailed study of 5-ASA-induced nephrotoxicity to date. It highlights the morbidity associated with this condition and identifies for the first time a significant genetic predisposition to drug-induced renal injury.

Abstract
BACKGROUND Antibiotic-associated diarrhoea (AAD) is a frequent complication of systemic antibiotic therapy and Clostridium difficile-associated diarrhoea (CDAD) is its most serious form due to associated morbidity and mortality. AIM This trial aimed to investigate whether the probiotic VSL#3 prevents AAD and CDAD in average-risk hospital patients. METHODS Adult hospital inpatients exposed to systemic antibiotics were recruited to this multicentre, randomized, double-blind, placebo-controlled trial. One sachet of VSL#3 or placebo was given twice daily for the length of the antibiotics course and for seven days thereafter. Primary outcomes were AAD and CDAD. FINDINGS Patients randomized to active (N = 117) and placebo (N = 112) groups were well-matched for baseline demographic patient data. No cases of CDAD were detected. The rate of AAD was significantly lower in the active group on per protocol analysis (0% active vs 11.4% placebo; P = 0.006). On intention-to-treat analysis the difference in AAD incidence (4.3% active vs 8.9% placebo; P = 0.19) was not significant. CONCLUSIONS VSL#3 is associated with a significant reduction in the incidence of AAD in average-risk hospital inpatients exposed to systemic antibiotics. As the incidence of CDAD has fallen sharply, no cases of CDAD were found. Probiotic administration as prophylaxis for CDAD may not be indicated in average-risk hospital patients.

Abstract
SUMMARY We performed a randomised controlled trial (RCT) to determine whether risedronate 35 mg once weekly prevents bone loss following an 8-week reducing course of prednisolone given for an exacerbation of inflammatory bowel disease (IBD). The greatest change in bone mineral density (BMD) was at Ward's triangle (WT), which fell by 2.2% in the placebo group, compared with a reduction of 0.8% in the risedronate group. INTRODUCTION Whether bisphosphonates can prevent bone loss associated with intermittent glucocorticoid (GC) therapy is unknown, reflecting the difficulty in performing RCTs in this context. METHOD To explore the feasibility of RCTs to examine this question, lumbar spine (LS; L2-4) and hip dual X-ray absorptiometry (DXA) scans were performed in 78 patients commencing a GC therapy course for a relapse of IBD. They were then randomised to receive placebo or risedronate 35 mg weekly for 8 weeks, after which the DXA scan was repeated. RESULTS For LS BMD, there was no change in the placebo group (0.1 +/- 0.4, p = 0.9), but there was an increase after risedronate (0.8 +/- 0.4, p = 0.04; mean% +/- SEM by paired Student's t test). There were small decreases in both groups at the total hip (-0.5 +/- 0.3, p = 0.04; -0.5 +/- 0.3, p < 0.05, placebo and risedronate, respectively). At WT, BMD fell after placebo (-2.2 +/- 0.5, p = 0.001) but not risedronate (-0.8 +/- 0.5, p = 0.09; p = 0.05 for between-group comparison). CONCLUSION RCTs can be used to examine whether bisphosphonates prevent bone loss associated with intermittent GC therapy, providing metabolically active sites such as WT are employed as the primary outcome.

Abstract
Hyperplastic Polyposis (HPPS) is a poorly characterized syndrome that increases colorectal cancer (CRC) risk. We aimed to provide a molecular classification of HPPS. We obtained 282 tumours from 32 putative HPPS patients with >or= 10 hyperplastic polyps (HPs); some patients also had adenomas and CRCs. We found no good evidence of microsatellite instability (MSI) in our samples. The epithelium of HPs was monoclonal. Somatic BRAF mutations occurred in two-thirds of our patients' HPs, and KRAS2 mutations in 10%; both mutations were more common in younger cases. The respective mutation frequencies in a set of 'sporadic' HPs were 18% and 10%. Importantly, the putative HPPS patients generally fell into two readily defined groups, one set whose polyps had BRAF mutations, and another set whose polyps had KRAS2 mutations. The most plausible explanation for this observation is that there exist different forms of inherited predisposition to HPPS, and that these determine whether polyps follow a BRAF or KRAS2 pathway. Most adenomas and CRCs from our putative HPPS patients had 'classical' morphology and few of these lesions had BRAF or KRAS2 mutations. These findings suggest that tumourigenesis in HPPS does not necessarily follow the 'serrated' pathway. Although current definitions of HPPS are sub-optimal, we suggest that diagnosis could benefit from molecular analysis. Specifically, testing BRAF and KRAS2 mutations, and perhaps MSI, in multiple polyps could help to distinguish HPPS from sporadic HPs. We propose a specific model which would have diagnosed five more of our cases as HPPS compared with the WHO clinical criteria.

Abstract
BACKGROUND AND STUDY AIMS Most trainees have little concept of the loops that occur during colonoscopy, and have difficulty in appreciating the combination of withdrawal and torquing manoeuvres that are essential to achieving complete colonoscopy. Real-time magnetic endoscope imaging (MEI) allows visualization of shaft looping, and so makes intuitive the manoeuvres necessary to straighten the colonoscope shaft. PATIENTS AND METHODS Consecutive routine colonoscopies were performed by a single trainee (with previous experience of 15 colonoscopies). Procedures were randomly assigned to be carried out either with the trainee viewing the MEI display, or without the MEI view, which was recorded throughout all examinations. RESULTS In total, 71 procedures were performed. To assess the trend for learning, procedures were analysed in blocks of 24 consecutive examinations (periods 1 to 3). In the first 24 procedures (period 1), the number of attempts at straightening the colonoscope and duration of looping were significantly less, and the intubation time was shorter, for examinations performed with the MEI view. In periods 2 to 3, there was a continued trend towards improved performance, but without a significant difference between procedures performed with or without MEI. CONCLUSIONS During training, real-time colonoscope imaging using MEI appears to enhance the endoscopist's appreciation of looping and improves the learning of the manoeuvres required to straighten the colonoscope shaft. A prospective, multicentre study assessing a larger number of trainees is needed to clarify these findings.

Abstract
The putative locus for hereditary mixed polyposis syndrome (HMPS) in a large family of Ashkenazi descent (SM96) was previously reported to map to chromosome sub-bands 6q16-q21. However, new clinical data, together with molecular data from additional family members, have shown 6q linkage to be incorrect. A high-density genomewide screen for the HMPS gene was therefore performed on SM96, using stringent criteria for assignment of affection status to minimize phenocopy rates. Significant evidence of linkage was found only on a region on chromosome 15q13-q14. Since this region encompassed CRAC1, a locus involved in inherited susceptibility to colorectal adenomas and carcinomas in another Ashkenazi family (SM1311), we determined whether HMPS and CRAC1 might be the same. We found that affected individuals from both families shared a haplotype between D15S1031 and D15S118; the haplotype was rare in the general Ashkenazi population. A third informative family, SM2952, showed linkage of disease to HMPS/CRAC1 and shared the putative ancestral haplotype, as did a further two families, SMU and RF. Although there are probably multiple causes of the multiple colorectal adenoma and cancer phenotype in Ashkenazim, an important one is the HMPS/CRAC1 locus on 15q13-q14.

Abstract
This article describes the work of the East Side Village Health Worker Partnership as a case study of an initiative that seeks to reduce the disproportionate health risks experienced by residents of Detroit's east side. The Partnership is a community-based participatory research and intervention collaboration among academia, public health practitioners, and the east side Detroit community. The Partnership is guided by a steering committee that is actively involved in all aspects of the research, intervention, and dissemination process, made up of representatives of five community-based organizations, residents of Detroit's east side, the local health department, a managed care provider, and an academic institution. The major goal of the East Side Village Health Worker Partnership is to address the social determinants of health on Detroit's east side, using a lay health advisor intervention approach. Data collected from 1996 to 2001 are used here to describe improvements in research methods, practice activities, and community relationships that emerged through this academic-practice-community linkage.

Abstract
The objective of this study was to evaluate a pocket Doppler device (Multi Dopplex II) for the waveform analysis of umbilical artery systolic/diastolic (S/D) ratios and resistance index (RI). A prospective, paired study was undertaken in a perinatal ultrasound unit in a tertiary referral hospital. Forty-three high-risk pregnant women beyond 16 weeks' gestation had fetal umbilical artery flow velocity waveforms recorded with both Multi Dopplex II and duplex Doppler devices and the waveform analyses were calculated. The Multi Dopplex II falsely indicated absent diastolic flow in two cases and failed to produce a flow velocity waveform in the presence of maternal obesity, polyhydramnios and some cases of anterior placenta (n = 8). As well as this, the limits of agreement overall for both S/D ratio and RI were wide (for S/D ratio, -1.6 to 2.2 and for RI, -0.20 to 0.20). Even though the levels of agreement were better for the third trimester (for S/D ratio, -0.8 to 1.1 and for RI, -0.10 to 0.20), we concluded that the limits of agreement were too wide for clinical use.
