Background & aims Pregnancy can be a complex and risk filled event for women with inflammatory bowel disease (IBD). High-quality studies in this population are lacking, with limited data on medications approved to treat IBD during pregnancy. For patients, limited knowledge surrounding pregnancy impacts pregnancy rates, medication adherence, and outcomes. Limited provider knowledge leads to highly varied practices in care affected by local dogma, available resources, individual interpretation of the literature, and fear of harming the fetus. The variations in guidelines by different societies and countries reflect this and lead to confusion for physicians and patients alike. The Global Consensus Consortium is a group of 39 IBD and content experts and 7 patient advocates from 6 continents who convened to review and assess current data and come to an agreement on best practices based on these data. Methods The GRADE process was used when sufficient published data were available and the RAND process in those instances where expert opinion was needed to guide consistent practice. Recommendations were informed by the guiding principle that maternal health best supports infant health. Results The topics were divided into ten categories with 34 GRADE recommendations and 35 Consensus statements. Conclusions Overall, the goal of the group was to provide data-driven and practical guidance to improve the care of women with IBD around the globe based on the best available research.

Limited provider knowledge leads to highly varied practices in care affected by local dogma, available resources, individual interpretation of the literature, and fear of harming the fetus.

Results: The topics were divided into 10 categories with 34 GRADE recommendations and 35 Consensus statements.

INTRODUCTION: To update the global burden of inflammatory bowel disease (IBD) using data from the Global Burden of Disease 2021. METHODS: Data from Global Burden of Disease 2021 were analyzed to assess the IBD burden. RESULTS: In 2021, there were 375,140 new cases and 3.83 million total cases of IBD. Elderly onset IBD accounted for 11% of incidences. 167 countries increased IBD incidence rate, with rates rising in female patients (APC: +0.06%) and the elderly (APC: +0.14%) but stable in male patients and the overall population. DISCUSSION: Although the global burden of IBD has decreased overall, it has increased in female patients and the elderly.

Abstract During the 20th century, inflammatory bowel disease (IBD) was considered a disease of early-industrialized regions in North America, Europe, and Oceania. At the turn of the 21st century, incidence of IBD increased in newly-industrialized and emerging regions in Africa, Asia, and Latin America, while prevalence in early-industrialized regions started to grow steadily. Changes in incidence and prevalence denote evolution of IBD across four epidemiologic stages: Stage 1 (Emergence), characterized by low incidence and prevalence; stage 2 (Acceleration in Incidence), characterized by rapidly rising incidence and low prevalence; and stage 3 (Compounding Prevalence), characterized by decelerating, plateauing, or declining incidence and steadily rising prevalence. A fourth stage (Prevalence Equilibrium) has been proposed where the slope of prevalence plateaus due to shifting demographics of an aging IBD population, but it has not yet been evidenced. To date, these stages have been theoretical without specific incidence/prevalence indicators defining transition points. Using real-world data from 490 population-based studies comprising 80 global regions and spanning over a century (1920–2023), we show spatiotemporal transitions across stages 1–3 and model transition towards stage 4. Understanding the evolution of IBD across epidemiologic stages allows healthcare systems to better prepare for the future worldwide burden of IBD.

Screening for colorectal cancer (CRC) is effective in reducing CRC related mortality. Current screening methods include endoscopy based and biomarker based approaches. This guideline is a joint official statement of the Asian Pacific Association of Gastroenterology (APAGE) and the Asian Pacific Society of Digestive Endoscopy (APSDE), developed in response to the increasing use of, and accumulating supportive evidence for the role of, non-invasive biomarkers for the diagnosis of CRC and its precursor lesions. A systematic review of 678 publications and a two stage Delphi consensus process involving 16 clinicians in various disciplines was undertaken to develop 32 evidence based and expert opinion based recommendations for the use of faecal immunochemical tests, faecal based tumour biomarkers or microbial biomarkers, and blood based tumour biomarkers for the detection of CRC and adenoma. Comprehensive up-to-date guidance is provided on indications, patient selection and strengths and limitations of each screening tool. Future research to inform clinical applications are discussed alongside objective measurement of research priorities. This joint APAGE–APSDE practice guideline is intended to provide an up-to-date guide to assist clinicians worldwide in utilising non-invasive biomarkers for CRC screening; it has particular salience for clinicians in the Asia-Pacific region.

INTRODUCTION: Peptic ulcer disease (PUD) is a common cause of hospitalization worldwide. We assessed temporal trends in hospitalization for PUD in 36 Organisation for Economic Co-operation and Development (OECD) countries since the turn of the 21st century. METHODS: The OECD database contains data on PUD-related hospital discharges and mortality for 36 countries between 2000 and 2019. Hospitalization rates for PUD were expressed as annual rates per 100,000 persons. Joinpoint regression models were used to calculate the average annual percent change (AAPC) with 95% confidence intervals (CIs) for each country, which were pooled using meta-analyses. The incidence of PUD was forecasted to 2021 using autoregressive integrated moving average and Poisson regression models. RESULTS: The overall median hospitalization rate was 42.4 with an interquartile range of 29.7–60.6 per 100,000 person-years. On average, hospitalization rates (AAPC = −3.9%; 95% CI: −4.4, −3.3) and morality rates (AAPC = −4.7%; 95% CI: −5.6, −3.8) for PUD have decreased from 2000 to 2019 globally. The forecasted incidence of PUD hospitalizations in 2021 ranged from 3.5 per 100,000 in Mexico to 92.1 per 100,000 in Lithuania. Across 36 countries in the OECD, 329,000 people are estimated to be hospitalized for PUD in 2021. DISCUSSION: PUD remains an important cause of hospitalization worldwide. Reassuringly, hospitalizations and mortality for PUD have consistently been falling in OECD countries in North America, Latin America, Europe, Asia, and Oceania. Identifying underlying factors driving these trends is essential to sustaining this downward momentum.
