BACKGROUND & AIMS: Pouchitis is the most common complication after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC), however clinical and environmental risk factors for pouchitis remain poorly understood. We explored the relationship between specific clinical factors and the incidence of pouchitis. METHODS: We established a population-based cohort of all adult persons in Denmark undergoing proctocolectomy with IPAA for UC from 1996-2020. We used Cox Proportional Hazard modeling to assess the impact of antibiotic, non-steroidal anti-inflammatory drug (NSAID) exposure, and appendectomy on diagnosis of acute pouchitis in the first 2 years after IPAA surgery...

BACKGROUND AND AIMS: The majority of patients with Familial Adenomatous Polyposis (FAP) develop duodenal adenomas with a risk of progression to duodenal cancer. Endoscopic management of FAP duodenal adenomas has been proposed as a less invasive option than surgery, but available data are still limited. Our aims were to assess the feasibility and safety of endoscopic treatment in duodenal polyposis and to evaluate its long-term efficacy in terms of recurrence and malignant degeneration...

BACKGROUND & AIMS: The considerable disease burden of irritable bowel syndrome (IBS) has coincided with the increase of ultraprocessed food (UPF) consumption over the past few decades. However, epidemiologic evidence is lacking. We aimed to examine the long-term risk of IBS associated with UPF consumption in a large-scale prospective cohort. METHODS: Participants who completed 24-hour dietary recalls during 2009 to 2012 from the UK Biobank, and free of IBS, celiac disease, inflammatory bowel disease, and any cancer at baseline, were included (N = 178,711; 53...

BACKGROUND AND AIMS: Nonalcoholic fatty liver disease (NAFLD) now known as metabolic dysfunction associated steatotic liver disease (MASLD) is closely associated with type 2 diabetes (T2D). Our aim was to estimate the most recent global prevalence of NAFLD/MASLD, non-alcoholic steatohepatitis (NASH) now known as metabolic dysfunction associated steatohepatitis (MASH), advanced fibrosis, and mortality among patients with T2D. METHODS: We systematically searched PubMed and Ovid MEDLINE for terms including NAFLD, NASH, and T2D published 1990-2023 according to PRISMA...

BACKGROUND & AIMS: Brain-gut behavior therapies (BGBT) are increasingly recognized as effective therapeutic interventions for functional heartburn. However, recommendations regarding candidacy for treatment, initial treatment selection, and navigating treatment non-response have not been established for functional heartburn specifically. The aim of this study was to establish expert-based recommendations for behavioral treatment in patients with functional heartburn. METHODS: The validated RAND/University of California, Los Angeles Appropriateness Method (RAM) was applied to develop recommendations...

BACKGROUND AND AIMS: Endoscopic Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC) detection is invasive and expensive. Non-endoscopic BE/EAC detection tools are guideline-endorsed alternatives. We previously described a 5-methylated DNA marker (MDM) panel assayed on encapsulated sponge cell collection device (CCD) specimens. We aimed to train a new algorithm using a 3-MDM panel and test its performance in an independent cohort. METHODS: Algorithm training and test samples were from two prospective multicenter cohorts...

BACKGROUND AND AIMS: Vedolizumab and ustekinumab pharmacokinetics in pregnancy and the infant following in-utero exposure remain incompletely defined. We aim to define the antenatal stability of ustekinumab and vedolizumab levels and the time at which infant drug levels become undetectable. METHODS: This multicentre prospective observational cohort study recruited pregnant or preconception women with Inflammatory Bowel Disease receiving vedolizumab or ustekinumab...

BACKGROUND & AIMS: Upadacitinib, an oral Janus kinase inhibitor, achieved significantly higher rates of clinical remission and endoscopic response vs placebo during induction (U-EXCEL [NCT03345849]; U-EXCEED [NCT03345836]) and maintenance (U-ENDURE [NCT03345823]) treatment in patients with moderate-to-severe Crohn's disease (CD). Prior biologic failure is often associated with reduced responses to subsequent therapies. This post hoc analysis assessed upadacitinib efficacy by prior biologic failure status...

BACKGROUND & AIMS: Upadacitinib (UPA), an oral Janus kinase inhibitor, is approved to treat moderately to severely active Crohn's disease (CD). As symptomatic response is an important initial treatment goal for patients, we evaluated the rapidity of symptomatic improvement in patients with CD receiving UPA 45 mg once daily (UPA45) induction therapy. METHODS: This post hoc analysis included pooled data from 2 phase 3, multicenter, double-blind 12-week induction trials (U-EXCEL and U-EXCEED) and 1 maintenance trial (U-ENDURE)...

BACKGROUND AND AIMS: Several studies have investigated the association between diverticular disease (DD) and colorectal cancer. However, whether there is an association between DD and malignancies other than those in the colorectum remains uncertain. METHODS: For the 1978-2019 period, we conducted a nationwide, population-based cohort study using national Danish healthcare data. We followed DD patients for up to 20 years, beginning one year after the date of DD diagnosis until the first occurrence of incident cancer, emigration, death, 20 years of follow-up, or December 31st , 2019...
