Design, setting, participants and outcome measures A retrospective cohort study was performed, including 147 UC patients treated with infliximab at a tertiary inflammatory bowel disease (IBD) centre. Primary outcome was corticosteroid-free clinical remission (CFCR) at week 14 and week 52. Patients were grouped according to prednisolone tapering regimens: standard (≤5 mg/week), fast (>5 mg/week), direct discontinuation or no prednisolone. Patients intolerant to corticosteroids and patients stopping corticosteroids in preparation for surgery including colectomy during their initial admission were excluded. Results There was no overall association between prednisolone exposure or no exposure and CFCR at weeks 14 or 52 of infliximab. The proportion of patients with C reactive protein ≤5 mg/L was higher in the standard tapering at week 14 as compared with faster regimens or no prednisolone. In subgroup analyses, the standard tapering was associated with a higher rate of CFCR at week 14 compared with the fast-tapering regimen in patients receiving ≥40 mg prednisolone at initiation of infliximab (64.3% vs 26.3%, p=0.04) and among patients admitted with acute severe UC (66.6% vs 23.5%, p<0.05). Similar data were seen at week 52. Prednisolone did not affect infliximab trough levels but increased infection rates (10/77 vs 2/70, p=0.03), in particular C. difficile infection. Conclusion In UC patients with limited disease burden, prednisolone did not affect effectiveness of infliximab. However, patients with increased disease burden seem to benefit from corticosteroid combination therapy. Data are available upon reasonable request.

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology and the population, intervention, comparison and outcome scheme were used. We included human-controlled trials that evaluate the current treatment for HRS. Two authors independently screened articles for inclusion, extracted data and assessed the quality of included studies. Results This study investigated the studies conducted on the effects of different treatments on follow-up of HRS patients. We gathered 440 articles, so 31 articles remained in our study. Of which 24 articles were conducted on terlipressin versus placebo or other treatments (midodrine/octreotide, norepinephrine, etc) that showed the higher rate of HRS reversal was detected for terlipressin in 17 studies (10 of them were significant), 2 studies achieved an insignificant lower rate of the model for end-stage liver disease score for terlipressin, 15 studies showed a decreased mortality rate in the terlipressin group (4 of them were significant).

We present the potential role of out of programme clinical fellowships. Method An electronic online survey was sent to all current fellows to understand their experiences, training opportunities and motivations. Data were collected on fellows’ endoscopic experiences and publications using PubMed for all previous doctors who have completed the Sheffield Fellowship Programme. Results Since 2004, 39 doctors have completed the Sheffield Fellowship. Endoscopic experience: current fellows completed a median average of 350 (IQR 150–500) gastroscopies and 150 (IQR 106–251) colonoscopies per year. Fellows with special interests completed either 428 hepato-pancreato-biliary procedures or 70 endoscopic mucosal resections per year. Medline publications: Median average 9 publications(IQR 4–17). They have also received multiple national or international awards and 91% achieved a doctoral degree. The seven current fellows in the new Shape of Training era (57% male, 29% Caucasian, aged 31–40 years) report high levels of enjoyment due to their research projects, supervisory teams and social aspects. The most cited reasons for undertaking the fellowship were to develop a subspecialty interest, take time off the on-call rota and develop endoscopic skills. The most reported drawback was a reduced income. All current fellows feel that the fellowship has enhanced their clinical confidence and prepared them to become consultants. Conclusion Out of programme clinical fellowships offer the opportunity to develop the required training competencies, subspecialty expertise and research skills in a supportive environment.

In the current study, we aimed to evaluate the safety and tolerability of the potential antifibrotic agent OP-724—a CREB-binding protein/β-catenin inhibitor—in this patient subset. Design In this single-centre, open-label, non-randomised, phase I trial, we sequentially enrolled patients with cirrhosis following HIV/HCV coinfection classified as Child-Pugh (CP) class A or B. Five patients received an intravenous infusion of OP-724 at doses of 140 or 280 mg/m2 for 4 hours two times weekly over 12 weeks. The primary endpoint was the incidence of serious adverse events (SAEs). Secondary endpoints included the incidence of AEs and improved liver stiffness measure (LSM), as determined by vibration-controlled transient elastography. This study was registered at ClinicalTrials.gov ([NCT04688034][1]). Results Between 9 February 2021 and 5 July 2022, five patients (median age: 51 years) were enrolled. All five patients completed 12 cycles of treatment. SAEs were not observed. The most common AEs were fever (60%) and gastrointestinal symptoms (diarrhoea: 20%, enterocolitis: 20%). Improvements in LSM and serum albumin levels were also observed. Conclusion In this preliminary assessment, intravenous administration of 140 or 280 mg/m2/4 hours OP-724 over 12 weeks was well tolerated by patients with haemophilia combined with cirrhosis due to HIV/HCV coinfection. Hence, the antifibrotic effects of OP-724 warrant further assessment in patients with cirrhosis. Trial registration number [NCT04688034][1]. Data are available upon reasonable request.

Design We assessed the risk of bias using the Cochrane tool, as indicators of poor methodology or subsequently poor reporting. We systematically selected, with dual independent judgements, all studies published on IBD with no time limits and assessed the methodological quality of included studies again using independent dual ratings. Results 563 full texts were included after selection and review. No abstract publications were free of any source of bias. Full-text publications still fared badly, as only 103 full-text papers exhibited a low risk of bias in all reporting domains when excluding blinding. RCTs published in journals with higher impact factor (IF) were associated with an overall reduced rate of being at high risk. However, only 6% of full RCT publications in journals with an IF greater than 10, published in the past 5 years, were free of bias. The trend over time is towards improved reporting in all areas. Trials published by larger author teams, in full-text form and by industry and public sponsorship were positively correlated with a lower risk of bias. Only allocation concealment showed a statistically significant improvement with time (p=0.037). Conclusion These findings are consistent with those of other specialties in the literature. While this unclear risk of bias may represent poor reporting of methods instead of poor methodological quality, it leaves readers and future secondary researchers with significant questions regarding such key issues.

Increased levels of potentially carcinogenic bile acids in faeces, theoretically, may increase the risk of colorectal cancer in particular, but the long-term disease course is unknown. We aimed to investigate the overall and site-specific cancer risk in bile acid diarrhoea. Design Adult patients with bile acid diarrhoea were identified using nationwide Danish registries from 2003 to 2020 by a diagnostic gold-standard 75-selenium tauroselcholic acid procedure followed within 6 months by sequestrant prescription. The risk of overall and site-specific cancers in cases with bile acid diarrhoea was compared with sex, age and comorbidity-adjusted matched controls. A competing risk model estimated cumulative incidence functions and cause-specific HRs. Results We identified 2260 patients with bile acid diarrhoea with a mean follow-up of 5.5 years (SD 4.2). The overall cancer risk was increased by an HR of 1.32 (95% CI 1.12 to 1.54). The risk of site-specific cancer was increased in 3 of 10 cancer groups: haematological, HR 2.41 (1.36 to 4.02); skin, HR 1.33 (1.01 to 1.71); and male genital cancers, HR 1.85 (1.11 to 2.92). No increased risk of colorectal cancer was detected in patients with bile acid diarrhoea, HR 0.73 (0.34 to 1.63). Conclusions Bile acid diarrhoea was associated with an increased overall risk of cancer, especially haematological cancers, but the risk of colorectal cancer was not increased. The lack of a diagnostic code for bile acid diarrhoea and potential residual confounding are limitations, and the findings should be replicated in other cohorts.

It is simple, concise, and treatment responsive, yet it has not been validated in the Persian language. This study aimed to translate the GERD-HRQL questionnaire into Persian and assess its validity and reliability. Design In this cross-sectional validation study, a team of gastroenterologists, general surgeons, and professional translators conducted the forward-backward translation. A gastroenterologist interviewed 10 patients with GORD to insure understandability of the questionnaire. Fifty-four patients with GORD and 60 patients with gastrointestinal complaints other than GORD were enrolled using convenience sampling method. To assess concurrent validity, patients with GORD completed the Persian GERD-HRQL and the WHO Quality of Life Brief Version (WHOQOL-BREF) questionnaires. To assess discriminant validity, GERD-HRQL scores were compared between GORD and non-GORD patients. After 2 weeks, the patients with GORD completed the GERD-HRQL questionnaire again to assess test–retest reliability. The internal consistency was measured using Cronbach’s alpha. Results The mean age of the GORD participants was 36.90±10.44, and the majority were women (78%). All GERD-HRQL domains and total scores exhibited significant negative correlations with WHOQOL-BREF domains (ranging from −0.28 to −0.97). The GERD-HRQL scores were significantly different in GORD and non-GORD patients (p<0.001). Test and retest scores did not show any significant differences (p=0.49). Cronbach’s alpha was 0.85. Conclusion The Persian GERD-HRQL questionnaire is valid and reliable and can effectively assess the GORD symptoms in Persian-speaking individuals. Data are available upon reasonable request.
