Capsule Gastric Endoscopy for Gastric Disease Screening in Simulated Home Scenarios

The goal of this clinical trial is to evaluate the diagnostic accuracy of the AI-integrated Capsule Gastroscopy (ACG) system in simulated home-use conditions for detecting upper gastrointestinal (UGI) abnormalities. It will also compare the diagnostic accuracy and time efficiency of AI-assisted interpretation versus manual reading of ACG data. The main questions it aims to answer are: What is the diagnostic accuracy of the ACG system, using conventional esophagogastroduodenoscopy (EGD) as a standard of reference? Does AI-assisted ACG reading improve diagnostic accuracy or reduce reading time compared to manual ACG video reading? Researchers will compare ACG results to conventional EGD findings (standard of reference) to determine if ACG can serve as a reliable method for UGI disease detection in home scenarios. Participants will: Undergo an ACG examination in a simulated home environment. Complete an EGD procedure within 24 hours post-ACG ingestion.

Circulating Biomarker Signatures for the Detection of Gastric Preneoplasia and Cancer

The goal of this study is to characterize and validate a signature of circulating biomarkers in plasma, associated with the presence of gastric preneoplasia in patients with preexisting gastric lesion compared with a control group. For this purpose: * Patients with pre-existing gastric lesions will be invited to participate to this study. If they are willing to participate an additional blood sample (9 mL) will be collected at the time of the blood collection performed during their routine care * Healthy subjects will be invited to participate to constitute the control group. If they are willing to participate a blood sample (9 ml) will be drawn specifically for this study

Lactobacillus Reuteri Strain Combination in Children Treated With PPI

Probiotics might be of help in preventing dysbiosis and emergence of SIBO. Gastrus consisted of a mixture of two human strains of L. Reuteri DSM 17938 and ATCC PTA 6475; the first have extensive data supporting its use in gastric infections (18) however, it lacks the anti-inflammatory properties that have been provided by L. Reuteri DSM ATCC PTA 6475 that has excellent acid resistance and has strong anti-inflammatory properties (19); for these reasons, Gastrus is the best candidate for this indication.

The EpiGASTRIC/EDGAR Project: New Strategies for the Early Detection and Prevention of Gastric Cancer

This study is a multicenter, prospective cohort study, which are planned to enroll at least 600 patients who diagnosed the primary gastric cancer (GC); around 50 patients with premalignant gastric lesions (PGLs) and early gastric neoplasias (EGC) treated by endoscopy resection; and no less than 600 healthy normal cohort participants, for more than 18 months in the Spanish population. All participants who enrolled in this registry will be questioned by the life habits survey; and clinical data and biological samples of these participants were analyzed in order to look for new diagnostic tools. The aim of this study is to evaluate clinical, endoscopic and molecular approaches to identify individuals with high-risk of GC. Thus, it would be allow the adoption of preventive measures to reduce mortality through early detection and/or the reduction of its incidence.
