Comparison of hemostatic ability between spray coagulation and forced coagulation modes in endoscopic submucosal dissection in patients with early gastric neoplasms: a study protocol for multicenter randomized controlled trial (Spray-G trial).

Background: Endoscopic submucosal dissection (ESD) is the standard treatment for early gastric neoplasms (EGN). Controlling intraoperative bleeding is crucial for ensuring safe and reliable procedures. ESD using the spray coagulation mode (SCM-ESD) has been developed to control bleeding more effectively than ESD using the conventional forced coagulation mode (FCM-ESD).

Safety and Efficacy of Sedation During Emergency Endoscopy for Upper Gastrointestinal Bleeding: A Propensity Score Matching Analysis.

Background And Aim: This study aimed to compare patients with and without sedation during emergency endoscopy for upper gastrointestinal bleeding (UGIB) and to clarify the safety and efficacy of sedation in emergency endoscopy.

Methods: We retrospectively collected 389 patients who underwent emergency endoscopy for UGIB at Ureshino Medical Center from 2016 to 2021. Patients were divided into two groups: sedation group during emergency endoscopy and nonsedation group.

Lifestyle- and comorbidity-related factors for the prescription of proton pump inhibitors after eradication in Japan.

Background And Aim: The aim of the present study was to examine the lifestyle- and comorbidity-related determinant factors of the prescription of proton pump inhibitors (PPIs) for patients in whom has been eradicated, and to evaluate the relationship between PPI prescription and the severity of endoscopic esophagitis.

Methods: This retrospective study included patients who underwent eradication from May 2012 to September 2016 at Saiseikai Karatsu Hospital. All patients received upper gastrointestinal endoscopy before eradication.

Effect of initial seeding density on cell behavior-driven epigenetic memory and preferential lineage differentiation of human iPSCs.

Understanding the cellular behavioral mechanisms underlying memory formation and maintenance in human induced pluripotent stem cell (hiPSC) culture provides key strategies for achieving stability and robustness of cell differentiation. Here, we show that changes in cell behavior-driven epigenetic memory of hiPSC cultures alter their pluripotent state and subsequent differentiation. Interestingly, pluripotency-associated genes were activated during the entire cell growth phases along with increased active modifications and decreased repressive modifications.

Aplastic Anemia in a Patient with Cronkhite-Canada Syndrome.

Cronkhite-Canada syndrome (CCS) is a rare polyposis disorder accompanied by alopecia and onychodystrophy. A 63-year-old man with a history of CCS and repeated embolism developed progressive thrombocytopenia and mild anemia. Laboratory testing, a bone marrow examination, and magnetic resonance imaging of the spine resulted in a diagnosis of concurrent aplastic anemia (AA).

Decline incidence in upper gastrointestinal bleeding in several recent years: data of the Japan claims database of 13 million accumulated patients.

This study was to examine the recent trends in upper gastrointestinal bleeding in Japan using a large-scale real-world database. The incidence of upper gastrointestinal bleeding was evaluated in the Japan Medical Data Center claims database of 13,019,713 patients aged 20 to 74 years with traceability for 3 months from 2009 to 2014. The incidence was compared with peptic ulcers and gastroesophageal reflux disease.

An Investigation of Nine Patients with Gastrointestinal Immune-Related Adverse Events Caused by Immune Checkpoint Inhibitors.

Introduction/aims: Immune checkpoint inhibitors (ICIs) sometimes cause immune-related adverse events (irAEs), of which there is little information in the literatures. The objective of this study was to characterize the clinical features of gastrointestinal irAEs (GI irAEs).

Materials And Methods: From a total of 250 patients who were administered anti-PD-1 antibodies (nivolumab and pembrolizumab), we retrospectively identified 9 patients with grade 2 or higher GI irAE based on medical records.

Risk Factors for Post-Endoscopic Retrograde Pancreatography Pancreatitis: A Retrospective Chart Review in a Regional Hospital in Japan.

Background: Endoscopic retrograde pancreatography (ERCP) is sometimes complicated by post-ERCP pancreatitis (PEP), which is a severe adverse effect.

Objective: The present study was performed to (i) evaluate the risk factors for PEP and (ii) compare the risk of PEP after ERCP performed in the off hours versus regular hours.

Methods: This retrospective study included 374 patients who underwent ERCP from January 2013 to December 2017.

A case-control study of the risk of upper gastrointestinal mucosal injuries in patients prescribed concurrent NSAIDs and antithrombotic drugs based on data from the Japanese national claims database of 13 million accumulated patients.

Background: We aimed to identify the adverse effects of nonsteroidal anti-inflammatory drugs (NSAIDs) and antithrombotics on the upper gastrointestinal (GI) mucosa in a clinical setting as a case-control study using a large-scale medical database in Japan.

Methods: We evaluated the risk of upper GI mucosal injuries in patients receiving NSAIDs and antithrombotics using the Japan Medical Data Center claims database with data for 13 million accumulated patients, from January 2009 to December 2014. Endoscopically evaluated upper GI mucosal injuries were peptic ulcers (n = 143,271), upper GI bleeding (n = 10,545), and gastroesophageal reflux disease (n = 154,755).
