A Colon-Targeted Oral Nanosystem Disrupts the Inflammatory Loop in Enteric Glia to Alleviate Ulcerative Colitis.

The gut's inflammation is governed by the enteric nervous system, where enteric glial cells (EGCs) serve as essential intermediaries between the nervous and immune systems. During inflammation, elevated levels of S100 calcium-binding protein B (S100B) from hyperactive EGCs initiate a proinflammatory cascade by inducing the excessive production of reactive oxygen species (ROS) and proinflammatory molecules, including S100B itself, thus establishing a detrimental feedback loop. Herein, we develop a S100B inhibitor pentamidine (PTM)-loaded olsalazine-based nanoneedle, Zn(Olsa)/PTM, to break this vicious cycle and alleviate ulcerative colitis.

Multi-Teacher Temporal Regulation Network for Surgical Workflow Recognition.

Automatic recognition of surgical workflow plays a vital role in modern operating rooms. Given the complex nature and extended duration of surgical videos, accurate recognition of surgical workflow is highly challenging. Despite being widely studied, existing methods still face two major limitations: insufficient visual feature extraction and performance degradation caused by inconsistency between training and testing features.

The Application of Multifunctional Endoscope Transport Carts in Bedside Endoscopy in Intensive Care Unit Patients.

Background: This study aimed to investigate whether the application of multifunctional endoscope transport carts, in bedside endoscopy in intensive care unit (ICU) patients, can improve the cleaning quality of the endoscopes.

Methods: A total of 175 endoscopes, used for bedside endoscopy in ICU patients in a hospital in China during November 2023 to January 2024, were randomly classified into the control group (n=88) and the experimental group (n=87). Multifunctional transport carts were used to deliver the endoscopes in the experimental group and traditionally used transport trolleys were used in the control group.

A Bio-Adaptive Janus-Adhesive Dressing with Dynamic Lubrication Overlayer for Prevention of Postoperative Infection and Adhesion.

Wound postoperative infection and adhesion are prevalent clinical conditions resulting from surgical trauma. However, integrating intraoperative repair and postoperative management into a dressing suitable for wounds with unpredictable surface shapes and surroundings remains a formidable challenge. Here, we attempt to introduce a dynamic antifouling surface as wound protective covering and report an in situ formation of slippery-adhesive Janus gel (SAJG) by assembling hydrogel (N-hydrosuccinimide ester-activated powders) and elastomer (Silicon oil-infused polydimethylsiloxane).

Artificial intelligence-based automated surgical workflow recognition in esophageal endoscopic submucosal dissection: an international multicenter study (with video).

Background: Endoscopic submucosal dissection (ESD) is a crucial yet challenging multi-phase procedure for treating early gastrointestinal cancers. This study developed an artificial intelligence (AI)-based automated surgical workflow recognition model for esophageal ESD and proposed an innovative training program based on esophageal ESD videos with or without AI labels to evaluate its effectiveness for trainees.

Methods: We retrospectively analyzed complete ESD videos collected from seven hospitals worldwide between 2016 and 2024.

Endoscopic removal of an embedded chicken bone in the esophagus: A case report.

Background: Sharp foreign body ingestion can cause gastrointestinal tract mucosa injury and requires proper endoscopic removal. Typically, protective devices are used to reduce mucosal damage. This case presents an alternative approach for the endoscopic removal of a large, irregular, and sharp foreign body (chicken bone) when traditional protective devices are inadequate, thus contributing to the management of such ingestions.

Double Band Ligation-Assisted Endoscopic Submucosal Resection for Rectal Neuroendocrine Tumors: Comparison With Conventional Endoscopic Mucosal Resection With Ligation (With Video).

Introduction: Based on endoscopic mucosal resection with ligation (EMR-L), we developed double band ligation-assisted endoscopic submucosal resection (ESR) for complete resection of small submucosal rectal neuroendocrine tumors (NETs). Both procedures use a multiband device to perform resection, with the only difference being that ESR adds an additional band to obtain deeper resection margin. The aim of this retrospective study was to validate its feasibility, safety, and effectiveness compared with EMR-L.

Efficacy of spray flushing in the reprocessing of flexible endoscopes: A randomized controlled trial.

Background: Commonly used cleaning brushes in the reprocessing of flexible endoscopes often cause damage within the working channels.

Aim: To develop a spray flushing system to achieving effective cleaning of the working channels while minimizing damage.

Methods: This prospective study included 60 used endoscopes and 60 Teflon tubes randomly divided into a control group ( = 30) and an experimental group ( = 30).

Correlation between tumor budding and the long-term follow-up outcomes after endoscopic submucosal dissection for superficial esophageal squamous cell carcinoma.

Background: The effect of tumor budding (TB) on the prognosis of patients with esophageal squamous cell carcinoma (ESCC) after endoscopic submucosal dissection (ESD) remains unclear. We evaluated the long-term outcomes of patients with superficial ESCC after ESD and the risk factors of TB for the long-term prognosis.

Methods: We conducted a retrospective study in a Chinese hospital.

Challenges in early detection and endoscopic resection of esophageal cancer: There is a long way to go.

The publication by Qu provided a comprehensive discussion about the epidemiology, etiology, histopathology, early detection, and endoscopic treatment of esophageal carcinoma (EC) and summarized the progress in the advanced technologies for screening and endoscopic resection for EC. In this editorial, we will provide deeper insight into the challenges that hinder practical application of these advanced technologies along with the role of these technologies in upper endoscopy quality. More efforts need to be made to overcome the challenges and add the value of these technologies in upper endoscopy quality.

Refining the targeted population and achieving better for colorectal cancer screening.

This editorial comments on the article entitled "Stage at diagnosis of colorectal cancer through diagnostic route: Who should be screened?" by Agatsuma , who conducted a retrospective study aiming at clarifying the stage at colorectal cancer (CRC) diagnosis based on different diagnostic routes. We share our opinion about CRC screening programs. The current situation suggests the need for a more specific and targeted population for CRC screening.

A Double Network Composite Hydrogel with Self-Regulating Cu/Luteolin Release and Mechanical Modulation for Enhanced Wound Healing.

Designing adaptive and smart hydrogel wound dressings to meet specific needs across different stages of wound healing is crucial. Here, we present a composite hydrogel, GSC/PBE@Lut, that offers self-regulating release of cupric ions and luteolin and modulates mechanical properties to promote chronic wound healing. The double network hydrogel, GSC, is fabricated through photo-cross-linking of gelatin methacrylate, followed by Cu-alginate coordination cross-linking.

Effect of vinegar supplementation on patients with esophageal lesions lightly stained with Lugol's iodine solution: Prospective single-centre trial.

Background: Esophageal chromoendoscopy with iodine solution is important for detecting early esophageal cancer. The effect of routine treatment for lesions lightly stained with Lugol's iodine solution is limited, and the addition of natural substances to a regular diet is becoming increasingly common. Vinegar has antitumor effects as reported in previous studies.
