Objectives: Endoscopic submucosal dissection (ESD) is a widely used approach for the resection of superficial gastric neoplastic lesions. Endoscopic mucosal resection (EMR) is acceptable for lesions <10–15 mm in size. Herein, we compared the clinical outcomes of ESD with those of EMR after circumferential precutting (EMR-P) for gastric adenomas ≤15 mm. Methods: We retrospectively analyzed the data of 213 patients with 228 gastric adenomas ≤15 mm in size who were treated endoscopically at a single tertiary hospital in Korea between November 2018 and October 2022. We evaluated the complete endoscopic resection rate, recurrence rate, procedure-related complications, and procedure time according to the procedure used. Results: Among the 228 gastric adenomas, 49 were treated with EMR-P and 179 with ESD. The histological complete resection rate was higher in the ESD group than in the EMR-P group (87% vs. 57%, p<0.001). No significant between-group differences were observed in endoscopic en bloc resection rates (ESD vs. EMR-P, 96% vs. 90%; p=0.081). The procedure time was significantly shorter in the EMR-P group than in the ESD group (28.9±19.7 min vs. 8.8±5.9 min, p<0.001). The local recurrence rate in patients with histologically incomplete resection did not differ between the two groups (ESD vs. EMR-P, 8.7% vs. 9.5%; p=0.924). Conclusions: For gastric adenomas ≤15 mm, EMR-P may be the preferable treatment method considering the en bloc resection rate, procedure time, and local recurrence rate. However, considering the complete resection rate, ESD is recommended as the treatment of choice for high-grade adenomas and early gastric cancer lesions.
Blood Concentrations of Lead, Cadmium, and Mercury Are Associated With Alcohol-Related Liver Disease

Background: An association between environmental pollutants and alcohol-related liver disease (ALD) has not been determined until now. The objectives of this study were to examine the association of the pollutants with ALD, and whether the pollutants together increased the risk of ALD. Methods: Data were extracted from the Korea National Health and Nutrition Examination Survey (2010–2013 and 2016–2017; n = 11,993). Blood levels of lead, cadmium, and mercury were measured. ALD was defined by a combination of excessive alcohol consumption and ALD/non-alcoholic fatty liver disease index > 0. The aspartate aminotransferase-to-platelet ratio index and fibrosis (FIB)-4 score were used to evaluate ALD FIB. Results: The odds ratios (ORs) of ALD for the highest versus the lowest quartiles of exposure were for lead, 7.39 (95% confidence interval [CI], 5.51–9.91); cadmium, 1.68 (95% CI, 1.32–2.14); and mercury, 5.03 (95% CI, 3.88–6.53). Adjusting for age, gender, smoking, occupation, education, and personal income attenuated the associations but indicated significant positive trends (all Ptrend < 0.001). A positive additive interaction between cadmium and lead was observed. The relative excess OR due to the interaction was 0.96 (95% CI, 0.41–1.51); synergy index = 2.92 (95% CI, 0.97–8.80). Among 951 subjects with ALD, advanced FIB was associated with lead and cadmium (OR, 3.46, 95% CI, 1.84–6.53; OR, 8.50, 95% CI, 2.54–28.42, respectively), but not with mercury. The effect estimates for lead and cadmium remained significant even after adjustment for daily alcohol intake. Conclusion: Blood levels of lead, cadmium, and mercury were significantly associated not only with the risk of ALD but also with ALD FIB. Cadmium and lead have synergistic effects that increase the risk of ALD.
제1자 관점의 가상현실(Virtual Reality) 콘텐츠 채널 효과: 프레즌스와 공감 인식의 순차적 매개모형을 중심으로

Despite the possibility of the practical application of advertising and public relations using virtual reality technics, related academic research is still lacking. This study conducted an experimental research(n=74) that exposed the campaign VR video content(The Source), which was already made to solve the African drinking water problem, through a first-party perspective and VR Head-mounted Display (VR HMD). The results of this study shows that the condition of first-party perspective and VR HMD channel has a higher level of presence perception and empathy than third-party and 2D monitor exposure. Furthermore, the effects of from the VR HMD channel to the willingness to participate in donations were mediated by the presence perception and empathy in the sequential mediation model. These findings not only empirically validate the communication effectiveness of VR as a medium but also provide a sequential model of VR marketing communication effectiveness in practice.
