Linked Color Imaging with Light-Emitting Diode Light Enhances the Visibility of Gastric Neoplasm: A Prospective, Multicenter, Comparative Trial.

Background: Early detection of gastric cancer can play a key role in improving prognosis. Recently, light-emitting diodes (LED) have been developed as novel endoscopic systems. However, the differences in the visibility of gastric neoplastic lesions between LED and laser endoscopy remains unclear.

Platelet activation through CD62P and the formation of platelet-monocyte complexes are associated with the exacerbation of mucosal inflammation in patients with ulcerative colitis.

Ulcerative colitis (UC) is a refractory, chronic inflammatory bowel disease of unknown etiology. Although platelets are activated in UC, their relevance in pathophysiology remains unclear. We analyzed the correlation of platelet activation and platelet-monocyte complexes (PMCs) with severity of mucosal inflammation using the Mayo endoscopic subscore (MES).

High neutrophil-to-lymphocyte ratio at eradication increases the risk of eradication failure and post-eradication gastric cancer.

Introduction: Vonoprazan has been known to have a high () eradication rate since its launch in 2015. Yet, the risk factors for eradication failure and development of post-eradication gastric cancer (GC) using VPZ regimen remain unclear.

Methods: This single-center cohort study included 934 consecutive patients who underwent eradication using VPZ between February 2015 and June 2017 and were followed up for five years by the end of 2022.

Poststreptococcal acute glomerulonephritis with 22F pneumococcal bacteremia.

Background: Pneumococcal vaccines have been available worldwide since the early 2000s; consequently, few reports exist of poststreptococcal acute glomerulonephritis (PSAGN) or complications of pneumococcal infection. We describe a patient with PSAGN and bacteremia with Streptococcus pneumoniae serotype 22F (not covered by the 13-valent pneumococcal vaccine (PCV 13)).

Case Diagnosis/treatment: A 5-year-old boy received the PCV13 vaccine and was admitted to our hospital with a fever and gross hematuria.

Development of an online neutron beam monitoring system for accelerator-based boron neutron capture therapy in a hospital.

Background: Boron neutron capture therapy (BNCT) is a next-generation radiotherapy, utilizing both an external neutron beam and a -containing pharmaceutical. A compact accelerator for a high intensity neutron source was installed to conduct BNCT in a hospital. The dose administered to a patient was evaluated by measuring the proton beam current.
