Digital twins in IBD-bridging data, biology and trial innovation

Apr 29, 2026

The authors investigate how digital twins, which are data-driven virtual replicas of individual patients, can revolutionize clinical trials in inflammatory bowel disease (IBD) by addressing challenges such as complexity, costs, and recruitment. They discuss the potential of digital twins to enhance trial design through adaptive randomization and synthetic control arms, while also highlighting the need for rigorous validation, ethical considerations, and data governance to ensure successful integration into IBD research.

JOSD1 drives hepatocellular carcinoma malignancy by modulating the ubiquitination-lactylation switch on PGAM1

Apr 28, 2026

The authors investigate the role of the deubiquitinase JOSD1 in the metabolic reprogramming of hepatocellular carcinoma (HCC) and its impact on tumor progression and immune response. They find that JOSD1 enhances glycolysis by modulating the ubiquitination-lactylation switch on PGAM1, leading to immune suppression and poor prognosis. Targeting JOSD1 may offer a promising therapeutic approach to improve treatment outcomes in HCC.

Metagenomic identification of gut microbiome signatures for accurate diagnosis and prognostic prediction of Epstein-Barr virus-associated nasopharyngeal carcinoma

Apr 28, 2026

The authors aimed to investigate the relationship between gut microbiome alterations and Epstein-Barr virus (EBV)-associated nasopharyngeal carcinoma (NPC) to enhance diagnostic and prognostic capabilities. Their findings revealed significant dysbiosis in the gut microbiome of NPC patients, with specific microbial species correlating with EBV DNA levels and patient mortality. The study demonstrates that microbiome-based diagnostic tools, especially when combined with EBV markers, show strong potential for improving NPC diagnosis and understanding its association with an immune-suppressive tumor microenvironment.

Next-generation AI for visually occult pancreatic cancer detection in a low-prevalence setting with longitudinal stability and multi-institutional generalisability

Apr 28, 2026

The authors aimed to develop and validate the Radiomics-based Early Detection MODel (REDMOD), an AI framework designed to detect visually occult pancreatic ductal adenocarcinoma (PDA) using standard CT imaging. In a multi-institutional study, REDMOD demonstrated significantly higher sensitivity for early PDA detection compared to radiologists, achieving an area under the curve (AUC) of 0.82 and maintaining strong longitudinal stability and generalizability across diverse datasets. These findings suggest that REDMOD could facilitate earlier diagnosis and intervention in high-risk populations, potentially improving survival outcomes.

The UK experience with hepatitis B immunoglobulin use following liver transplantation: wide variation in practice despite evidence supporting cost-effective HBIG-free prophylaxis

Apr 27, 2026

This study investigates the current practices and outcomes of hepatitis B immunoglobulin (HBIG) use for prophylaxis against hepatitis B virus recurrence following liver transplantation in the UK. The authors found significant variability in HBIG protocols among transplant centers, with most patients receiving HBIG regardless of their recurrence risk, yet the findings suggest that HBIG maintenance-free strategies could be both feasible and cost-effective, as they do not significantly impact patient outcomes. The study calls for further prospective research to validate these results and promote broader adoption of HBIG-free approaches.

Differential intrahepatic integrated HBV DNA patterns between HBeAg-positive and HBeAg-negative chronic hepatitis B

Apr 24, 2026

The authors aimed to investigate the differences in intrahepatic covalently closed circular DNA (cccDNA) and integrated hepatitis B virus (HBV) DNA (iDNA) patterns between HBeAg-positive and HBeAg-negative chronic hepatitis B (CHB) patients. They found that HBeAg-positive patients had higher levels of cccDNA and associated biomarkers, while HBeAg-negative patients exhibited a greater proportion of iDNA, particularly clustered at specific integration sites, suggesting that iDNA may be the primary source of hepatitis B surface antigen (HBsAg) in this group. This study highlights the distinct virological characteristics and potential implications for disease progression in HBeAg-positive versus HBeAg-negative CHB.

Gastric microbiota-mediated immune remodelling in gastric cancer

Apr 22, 2026

The authors review the role of gastric microbiota in shaping the tumor microenvironment (TME) and its implications for gastric cancer (GC) progression and treatment. They explore how specific bacteria influence immune cell populations and the potential of microbiota-targeting strategies to enhance the efficacy of immunotherapy, particularly immune checkpoint blockade. The paper aims to elucidate the interactions between the gastric microbiota and immune responses in GC to inform future precision medicine approaches.

Norepinephrine promotes tumour cell aggressiveness and NK cell ferroptosis via ADRB2 in intrahepatic cholangiocarcinoma with perineural invasion

Apr 20, 2026

The authors investigate the role of sympathetic signaling, specifically norepinephrine (NE) and its interaction with ADRB2, in promoting tumor aggressiveness and inducing ferroptosis in natural killer (NK) cells within intrahepatic cholangiocarcinoma (iCCA) characterized by perineural invasion (PNI). They reveal that NE enhances tumor progression through the upregulation of MDK and decreases NK cell infiltration, suggesting that targeting β-adrenergic signaling could be a potential therapeutic strategy for managing PNI+ iCCA.

Circulating extracellular vesicle long RNA profiling combined with machine learning unveils novel diagnostic signature and molecular features in chronic pancreatitis

Apr 16, 2026

The authors aimed to develop a non-invasive diagnostic model for chronic pancreatitis (CP) using long RNA profiles from circulating extracellular vesicles (ExLRs) and to characterize the molecular features of CP. They successfully constructed the ExLRCPdscore model, which demonstrated high accuracy in detecting CP, including early-stage cases and those without significant symptoms or imaging findings. This study highlights the potential of ExLRs as both diagnostic tools and for understanding the pathophysiology of CP.

Targeting PKM2-dependent glycolysis reprogrammes monocytes into Cadm1⁺ macrophages to promote mucosal repair and attenuate colitis progression

Apr 15, 2026

The authors aimed to determine whether modulating macrophage metabolism, specifically targeting PKM2-dependent glycolysis, could promote mucosal healing in ulcerative colitis (UC) without increasing the risk of tumorigenesis. Their findings indicate that PKM2 depletion in macrophages enhances intestinal barrier function and promotes the differentiation of reparative Cadm1⁺ macrophages, ultimately leading to improved mucosal repair and reduced colitis progression in mouse models. Importantly, this approach was associated with a decrease in tumorigenesis, suggesting a potential therapeutic strategy for UC.
