Clinical significance of cachexia index determined by bioelectrical impedance analysis in patients with gastrointestinal cancer.

Cancer cachexia is a complex disorder characterized by skeletal muscle loss, which may influence the prognosis of patients with cancer. The cachexia index (CXI) is a new index for cachexia. The present study aimed to assess whether the CXI determined by bioelectrical impedance analysis (BIA) is valuable for predicting survival in patients with gastrointestinal cancer.

Endoscopic hemostasis with a self-assembling peptide gel during endoscopic submucosal dissection and cold-snare polypectomy in the duodenum: Prospective exploratory study (with video).

Objectives: A novel self-assembling peptide gel (SAPG) was recently developed for hemostasis during endoscopic resection (ER) as an alternative for electrocoagulation and clip placement. Therefore, this exploratory study aimed to evaluate the hemostatic effect of SAPG on bleeding during ER of the duodenum.

Methods: Patients with superficial duodenal epithelial tumors who underwent endoscopic submucosal dissection (ESD) or cold-snare polypectomy (CSP) between June 2022 and October 2023 were enrolled in the study.

The relation in MreB and intrabacterial nanotransportation system for VacA in Helicobacter pylori.

Helicobacter pylori possesses an intrabacterial nanotransportation system (ibNoTS) for transporting VacA, CagA, and urease within the bacterial cytoplasm. This system is controlled by the extrabacterial environment. The transport routes of the system for VacA have not yet been studied in detail.
