Prognostic performance of liver stiffness measurements in primary sclerosing cholangitis: the prospective FICUS cohort

Aug 4, 2026

The authors aimed to validate the prognostic value of liver stiffness measurements (LSM) in predicting outcomes for patients with primary sclerosing cholangitis (PSC) in a large, prospective cohort study. They found that both baseline and dynamic LSM are strongly associated with transplant-free survival, indicating that LSM can serve as an effective risk stratification tool and potential surrogate endpoint in clinical trials for PSC.

AI-Assisted Risk Stratification in Stage II Colorectal Cancer: Multi-Institutional Validation of Semantically-Enhanced Deep Learning

Jul 28, 2026

The authors aimed to develop and validate an AI-based tool, SÉMIL, for automated assessment of invasiveness in stage II colorectal cancer to improve risk stratification for treatment decisions. Their findings indicate that SÉMIL outperforms traditional methods in predicting patient outcomes and effectively stratifies high-risk patients according to established guidelines, suggesting its potential utility in clinical practice for more accurate treatment planning.

Serotonergic signaling in gastric physiology and motility disorders

Jul 22, 2026

The authors investigate the role of serotonergic signaling in gastric physiology and its implications for motility disorders, aiming to clarify its therapeutic potential and identify evidence gaps. They highlight the importance of serotonin in regulating gastric function and discuss the evolving landscape of serotonergic therapies, particularly focusing on the efficacy of newer agents like 5-HT4 agonists. The review underscores the need for further research to evaluate the effectiveness of these treatments in managing gastric motility disorders.

A DR5/Ligase 3-mediated feedback loop perpetuates immunogenicity in mismatch repair deficient colorectal cancer

Jul 16, 2026

The authors investigate the mechanisms behind the immunogenicity of mismatch repair deficient (dMMR) colorectal cancer (CRC) and its implications for immune checkpoint inhibitor (ICI) therapy. They identify a feedback loop involving DR5 and Ligase 3 that enhances antitumor immune responses and apoptosis in dMMR tumors, suggesting that this mechanism could explain variability in ICI responses among patients. Their findings highlight the potential for targeting this feedback loop to improve ICI therapy across different MMR statuses in CRC.

Harmonized metagenomic signatures of the gut microbiome reveal robust species, functions, and strain links to inflammatory bowel disease

Jul 14, 2026

The authors aimed to investigate the gut microbiome's role in inflammatory bowel disease (IBD) by analyzing metagenomic data from 2,371 stool samples across multiple cohorts. They identified specific pro-inflammatory taxa and strain-level differences that distinguish Crohn's disease from ulcerative colitis, revealing significant shifts in microbial functions related to carbohydrate metabolism and virulence. The findings suggest that the microbial clades associated with IBD exhibit diverse functionalities influenced by species and strain variations, contributing to disease pathogenesis.

SOX9-driven SPEM cell lineage plasticity is a potential therapeutic target that mitigates risk of metaplastic progression to gastric cancer

Jul 14, 2026

The authors investigate the role of SOX9 in the plasticity of spasmolytic polypeptide-expressing metaplastic (SPEM) cells during gastric carcinogenesis, aiming to understand how SOX9 influences metaplasia development and progression to gastric cancer. Their findings reveal that loss of SOX9 in chief cells prevents metaplasia and disrupts the progression of carcinogenesis, highlighting SOX9 as a critical regulator of SPEM cell lineage evolution and a potential therapeutic target to mitigate gastric cancer risk.

Molecular Subtypes of Cholangiocarcinoma and their Translational Implications

Jul 13, 2026

The authors aim to elucidate the molecular subtypes of cholangiocarcinoma and their translational implications, highlighting the significant heterogeneity in their etiologies and histopathological characteristics. They explore the genetic and epigenetic factors contributing to this diversity, the actionable targets for treatment, and the potential impact of environmental and biological factors on tumor behavior. The review emphasizes the need for a better understanding of these molecular distinctions to improve therapeutic strategies and address existing knowledge gaps.

Long-term incidence of hepatocellular carcinoma after hepatitis B surface antigen seroclearance

Jul 13, 2026

The authors aimed to assess the long-term incidence of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB) who achieved hepatitis B surface antigen (HBsAg) seroclearance, compared to the general population. Their findings indicate that individuals who clear HBsAg, particularly younger men and women without cirrhosis, exhibit a very low risk of developing HCC, suggesting that routine surveillance may not be necessary for these groups.

Acupuncture versus sham non-acupoint acupuncture for irritable bowel syndrome: a systematic review and meta-analysis

Jul 7, 2026

This systematic review and meta-analysis aimed to evaluate the efficacy of acupuncture compared to sham non-acupoint acupuncture in treating irritable bowel syndrome (IBS). The results indicated that acupuncture significantly improved the response rate, symptom severity, and quality of life for IBS patients compared to the sham treatment. However, the authors noted significant heterogeneity and low certainty of evidence, suggesting the need for further high-quality trials to confirm these findings.

BIRC3 (Encoding Cellular Inhibitor of Apoptosis Protein 2) Variants Result in Dysregulated Receptor-Interacting Protein Kinase 1 Signaling Leading to Increased Epithelial Cell Death and Are Associated With Monogenic Crohn's Disease

Jun 23, 2026

The authors investigate the role of BIRC3 gene variants in monogenic Crohn's disease (CD) and their impact on receptor-interacting protein kinase 1 (RIPK1) signaling. They identify rare BIRC3 variants in patients with CD, demonstrating that these variants lead to dysregulated RIPK1 signaling and increased epithelial cell death, ultimately contributing to intestinal inflammation. The study highlights RIPK1 as a potential therapeutic target for treating BIRC3 deficiency-related CD.
