The Korean Society of Gastrointestinal Endoscopy (KSGE) developed a gastrointestinal (GI) endoscopy board in 1995 and related regulations. Although the KSGE has acquired many specialists since then, the education and training aims and guidelines were insufficient. During GI fellowship training, obtaining sufficient exposure to some types of endoscopic procedures is difficult. Fellows should acquire endoscopic skills through supervised endoscopic procedures during GI fellowship training. Thus, the KSGE requires training guidelines for fellowships that allow fellows to perform independent endoscopic procedures without supervision...

Edwardsiellosis is a major fish disease that causes a significant economic damage in the aquaculture industry. Here, we assessed vaccine efficacy after feeding oral vaccines to olive flounder (Paralichthys olivaceus), either L. lactis BFE920 expressing Edwardsiella tarda outer membrane protein A (OmpA), flagellar hook protein D (FlgD), or a fusion antigen of the two. Feed vaccination was done twice with a one-week interval. Fish were fed regular feed adsorbed with the vaccines. Feed vaccination was given over the course of one week to maximize the interaction between the feed vaccines and the fish intestine...

The volume of hip arthroplasty is stiffly increasing because of excellent clinical outcomes, however it has not been shown to decrease the incidence of transfusions due to bleeding related to this surgery. This is an important consideration since there are concerns about the side effects and social costs of transfusions. First, anemia should be assessed at least 30 days before elective hip arthroplasty, and if the subject is diagnosed as having anemia, an additional examination of the cause of the anemia should be carried and steps taken to address the anemia...

Background. Three nomogram models for early stage uterine cervical cancer have been developed (KROG 13-03 for overall survival [OS], SNUH/AMC for disease-free survival [DFS], and KROG 12-08 for distant metastases-free survival [DMFS]) after radical hysterectomy (RH) and pelvic lymph node dissection (PLND). This study aimed to validate these models using our cohort with adjuvant radiotherapy. Methods. According to the eligibility criteria of nomogram studies, patients were enrolled in Group A (N = 109) for the two KROG models (RH with PLND and whole pelvic irradiation) and Group B (N = 101) for the SNUH/AMC model (RH with PLND and squamous histology)...

The optimal decision regarding whether to repair or replace the tricuspid valve (TV) remains controversial in patients with very severe functional tricuspid regurgitation (TR). We sought to compare clinical outcomes of TV repair versus replacement for very severe TR associated with severe TV tethering. We included 96 consecutive patients (20 men, 58 ± 11 years of age) who had both severe tethering of TV and very severe functional TR and consequently underwent TV surgery during left-sided valve surgery. TV repair was performed on 79 patients (repair group), whereas 17 patients underwent TV replacement (replacement group)...
