Cirrhosis remains a major global cause of morbidity and mortality, with rapidly evolving etiologic drivers. This review summarizes the contemporary global epidemiology of cirrhosis, highlighting regional patterns and major transitions in underlying causes to inform prevention and policy. In 2021, cirrhosis and chronic liver disease accounted for ~1.4 million deaths worldwide. Although age-standardized mortality rates have declined in many regions, the absolute burden continues to rise due to population growth and aging. Reductions in hepatitis B and C–related cirrhosis, driven by vaccination, screening, and antiviral therapy, have been offset by a growing contribution from steatotic liver disease. High–sociodemographic index (SDI) regions exhibit lower mortality but increasing prevalence, reflecting improved survival and expanding metabolic risk, whereas low- and lower-middle–SDI regions continue to experience high mortality. Addressing the global burden of cirrhosis will require sustained public health investment focused on viral hepatitis elimination, alcohol-associated harm reduction, metabolic risk management, and equitable access to early detection and care.

ABSTRACT Background and Aim Determining the location of gastrointestinal (GI) bleeding is critical for guiding diagnostic and therapeutic strategies but often results in patients receiving pan‐endoscopy with upper endoscopy, colonoscopy, and small bowel capsule endoscopy, which can be unnecessary, costly, and waste limited healthcare resources. The blood urea nitrogen‐to‐creatinine ratio (BUN/Cr) may help discriminate between upper GI bleeding (UGIB) and lower GI bleeding (LGIB). This study aims to assess the diagnostic performance of the BUN/Cr in distinguishing UGIB from LGIB. Methods A literature search was conducted in MEDLINE, EMBASE, and Cochrane Library to identify diagnostic test accuracy studies published from inception through January 31, 2025, which evaluated BUN/Cr in patients with UGIB versus LGIB. A linear mixed‐effects model meta‐analysis was conducted using the “diagmeta” package. The pooled sensitivity, specificity, diagnostic odds ratio, and area under the summary receiver operating characteristic curve (AUC) were estimated, and optimal threshold was determined using the Youden index. Results Seventeen studies were included in this meta‐analysis. The pooled mean difference in BUN/Cr between UGIB and LGIB patients was 11.44 (95% confidence interval [95% CI] 8.35–14.52). At a threshold of > 30, pooled sensitivity was 38.8% (95% CI 28.1%–50.8%) and specificity was 89.3% (95% CI 81.0%–94.2%). At the optimal cut‐off of 22, sensitivity was 66.2% (95% CI 57.8%–73.7%), specificity was 71.0% (95% CI 58.5%–81.0%), and AUC was 0.740 (95% CI 0.683–0.794). Conclusion BUN/Cr demonstrates moderate diagnostic accuracy for distinguishing UGIB from LGIB, particularly at a threshold of ≥ 22. This readily accessible and inexpensive blood test may assist in early clinical triage and assessment of the location of GI bleeding, particularly in those patients where the clinical presentation is obscure.

Abstract Background Gastrointestinal (GI) cancer remains a major global health challenge. This study provides updated 2022 estimates of GI cancer incidence and mortality worldwide, along with projections of incident cases and deaths through 2050 to inform cancer control strategies. Methods In this population‐based study, data from the GLOBOCAN 2022 database were used to examine incidence and deaths associated with GI cancer. By using global demographic projections, this study estimated the projected number of incident cases and deaths until the year 2050. Results By 2050, the global burden of GI cancer is projected to reach 9.06 million incident cases (+85%) and 6.42 million deaths (+93%) from 2022. Increases in incidence are projected for both females (+87%) and males (+83%), as are increases in mortality for both females (+97%) and males (+91%). Whereas the Western Pacific region will have the highest absolute burden, with 3.88 million new cases and 2.79 million deaths, the greatest relative increase is expected in Africa, with incidence and deaths rising by 157% and 160%, respectively. As measured by the Human Development Index (HDI), the steepest increases are projected in low (+151% incidence; +152% deaths) and medium (+112% incidence; +114% deaths) HDI countries. Overall, all GI cancer types are projected to increase, led by pancreatic cancer in incidence (+95%) and colorectal cancer in deaths (+103%). Conclusions GI cancer incidence and deaths are expected to nearly double by 2050, with increases across sexes, cancer types, and regions, especially in lower HDI countries.

ABSTRACTBackgroundMetabolic dysfunction‐associated steatotic liver disease (MASLD) affects over one third of the global population and is closely linked to gastrointestinal, oncological, and cardiovascular diseases. As the most common cause of steatotic liver disease (SLD), MASLD is often referred to as “fatty liver” in general health information searches. With the Internet becoming a primary source of healthcare information, this study aimed to evaluate global and regional public interest in steatotic liver disease using Google Trends data from January 2004 to December 2024.MethodsA comprehensive analysis was performed using Google Trends with the search term “fatty liver disease.” Interest levels were quantified using Google Trends indices, and temporal patterns were evaluated using average annual percent change (AAPC). Regional variations were assessed to identify geographic hotspots of public interest.ResultsGlobal interest in MASLD demonstrated significant growth (AAPC: 6.77%, 95% Confidence interval [CI]: 5.33–8.23), with a 264% increase from 2004 to 2024. Peak interest was observed in August 2024 (index: 100) compared to the lowest point in June 2007. Iran showed the highest country‐specific search volume (index: 100), while within the United States, West Virginia demonstrated the greatest relative interest (index: 100). Key topics associated with MASLD included “liver,” “symptoms,” “disease,” and “therapy.”ConclusionsSubstantial growth in global public interest in MASLD, with distinct temporal and geographical patterns, provides insights to develop targeted awareness campaigns and educational interventions, particularly in regions with low search volumes. Future research should examine the relationship between online search patterns and clinical outcomes in MASLD.

INTRODUCTION: DeepSeek was evaluated in gastroenterology board examination performance against legacy ChatGPT offline models, which previously showed failing performance. METHODS: The performances of the DeepSeek base R1 model and search-augmented R1 model were assessed using American College of Gastroenterology self-assessments (455 questions). RESULTS: DeepSeek exceeded the passing threshold. Search-augmented DeepSeek scored 81.5% across all questions, and the R1 base model scored 77.1%. Both search-augmented and offline DeepSeek models surpassed offline ChatGPT-3 (65.1%) and ChatGPT-4 (62.4%) ( P < 0.001). DISCUSSION: DeepSeek exhibited passing performance on the gastroenterology board examination but had gaps in niche topics and image exclusion limit utility. It may supplement education if validated by specialists.

Backgrounds and Aims: HBV-related liver disease ranks as the seventh leading cause of mortality. Despite advances in prevention and treatment, global disparities in the burden of primary liver cancer (PLC) persist. We evaluate global trends in the prevalence, incidence, and death of HBV-related liver disease. Approach and Results: Data from the Global Burden of Disease Study 2021 evaluated acute HBV infection, HBV-related cirrhosis, and HBV-related liver cancer prevalence, incidence, and death. In 2021, there were 7.30 million cases of acute HBV, 283.64 million cases of HBV-related cirrhosis, and 288,110 cases of HBV-related PLC. HBV-related PLC accounted for 39% of the global incidence of PLC; Western Pacific had the highest rates for HBV-related PLC, with an incidence of 5.24 and a death rate of 4.38 per 100,000 population. Between 2000 and 2021, age-standardized incidence, prevalence, and death rates from HBV-related liver disease decreased; however, the incidence of HBV-related PLC rose in 65 countries from 2000 to 2021. In parallel, age-standardized prevalent rates from HBV-related PLC increased in Europe (annual percent change: 0.77%, 95% CI: 0.72%–0.81%) and the Americas (annual percent change: 1.05%, 95% CI: 1.00%–1.10%). Conclusions: From 2000 to 2021, decreases in HBV-related liver disease incidence and prevalence were observed; however, more than one-third of countries showed an increase in the incidence of HBV-related PLC. These findings highlight the need for strengthened HBV treatment efforts to reduce the risk of liver cancer.

INTRODUCTION: This study investigates seasonal variations in eosinophilic esophagitis (EoE)-related emergency department visits among adults. METHODS: We analyzed the National Emergency Department Sample (2016–2021), identifying adult patients with EoE using ICD-10 codes. Generalized additive models assessed seasonal patterns. RESULTS: Among 18,791 EoE-related emergency department visits, a significant seasonal variation was observed, peaking in summer and nadiring in winter. This pattern was consistent across all US regions. CONCLUSION: Seasonal dietary habits and social behaviors likely contribute to EoE exacerbations. Healthcare providers should emphasize management strategies during high-risk periods, particularly summer months and weekends.
