		                        			 Background/Aims:
		                        			Chronic hepatitis B (CHB) is related to an increased risk of extrahepatic malignancy (EHM), and antiviral treatment is associated with an incidence of EHM comparable to controls. We compared the risks of EHM and intrahepatic malignancy (IHM) between entecavir (ETV) and tenofovir disoproxil fumarate (TDF) treatment. 
		                        		
		                        			Methods:
		                        			Using data from the National Health Insurance Service of Korea, this nationwide cohort study included treatment-naïve CHB patients who initiated ETV (n=24,287) or TDF (n=29,199) therapy between 2012 and 2014. The primary outcome was the development of any primary EHM. Secondary outcomes included overall IHM development. E-value was calculated to assess the robustness of results to unmeasured confounders. 
		                        		
		                        			Results:
		                        			The median follow-up duration was 5.9 years, and all baseline characteristics were well balanced after propensity score matching. EHM incidence rate differed significantly between within versus beyond 3 years in both groups (P<0.01, Davies test). During the first 3 years, EHM risk was comparable in the propensity score-matched cohort (5.88 versus 5.84/1,000 person-years; subdistribution hazard ratio [SHR]=1.01, 95% confidence interval [CI]=0.88–1.17, P=0.84). After year 3, however, TDF was associated with a significantly lower EHM incidence compared to ETV (4.92 versus 6.91/1,000 person-years; SHR=0.70, 95% CI=0.60–0.81, P<0.01; E-value for SHR=2.21). Regarding IHM, the superiority of TDF over ETV was maintained both within (17.58 versus 20.19/1,000 person-years; SHR=0.88, 95% CI=0.81–0.95, P<0.01) and after year 3 (11.45 versus 16.20/1,000 person-years; SHR=0.68, 95% CI=0.62–0.75, P<0.01; E-value for SHR=2.30). 
		                        		
		                        			Conclusions
		                        			TDF was associated with approximately 30% lower risks of both EHM and IHM than ETV in CHB patients after 3 years of antiviral therapy.

		                        			 Background:
		                        			/Aim: Atezolizumab plus bevacizumab and lenvatinib are currently available as first-line therapy for the treatment of unresectable hepatocellular carcinoma (HCC). However, comparative efficacy studies are still limited. This study aimed to investigate the effectiveness of these treatments in HCC patients with portal vein tumor thrombosis (PVTT). 
		                        		
		                        			Methods:
		                        			We retrospectively included patients who received either atezolizumab plus bevacizumab or lenvatinib as first-line systemic therapy for HCC with PVTT. Primary endpoint was overall survival (OS), and secondary endpoints included progressionfree survival (PFS) and disease control rate (DCR) determined by response evaluation criteria in solid tumors, version 1.1. 
		                        		
		                        			Results:
		                        			A total of 52 patients were included: 30 received atezolizumab plus bevacizumab and 22 received lenvatinib. The median follow-up duration was 6.4 months (interquartile range, 3.9-9.8). The median OS was 10.8 months (95% confidence interval [CI], 5.7 to not estimated) with atezolizumab plus bevacizumab and 5.8 months (95% CI, 4.8 to not estimated) with lenvatinib (P=0.26 by log-rank test). There was no statistically significant difference in OS (adjusted hazard ratio [aHR], 0.71; 95% CI, 0.34-1.49; P=0.37). The median PFS was similar (P=0.63 by log-rank test), with 4.1 months (95% CI, 3.3-7.7) for atezolizumab plus bevacizumab and 4.3 months (95% CI, 2.6-5.8) for lenvatinib (aHR, 0.93; 95% CI, 0.51-1.69; P=0.80). HRs were similar after inverse probability treatment weighting. The DCRs were 23.3% and 18.2% in patients receiving atezolizumab plus bevacizumab and lenvatinib, respectively (P=0.74). 
		                        		
		                        			Conclusion
		                        			The effectiveness of atezolizumab plus bevacizumab and lenvatinib was comparable for the treatment of HCC with PVTT.

		                        			 Background/Aims:
		                        			Chronic hepatitis B (CHB) is a risk factor for non-Hodgkin lymphoma (NHL). Our recent study suggested that antiviral treatment may reduce the incidence of NHL in CHB patients. This study compared the prognoses of hepatitis B virus (HBV)-associated diffuse large B-cell lymphoma (DLBCL) patients receiving antiviral treatment and HBV-unassociated DLBCL patients. 
		                        		
		                        			Methods:
		                        			This study comprised 928 DLBCL patients who were treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) at two referral centers in Korea. All patients with CHB received antiviral treatment. Time-to-progression (TTP) and overall survival (OS) were the primary and secondary endpoints, respectively. 
		                        		
		                        			Results:
		                        			Among the 928 patients in this study, 82 were hepatitis B surface antigen (HBsAg)-positive (the CHB group) and 846 were HBsAg-negative (the non-CHB group). The median follow-up time was 50.5 months (interquartile range [IQR]=25.6–69.7 months). Multivariable analyses showed longer TTP in the CHB group than the non-CHB group both before inverse probability of treatment weighting (IPTW; adjusted hazard ratio [aHR]=0.49, 95% confidence interval [CI]=0.29–0.82, p=0.007) and after IPTW (aHR=0.42, 95% CI=0.26–0.70, p<0.001). The CHB group also had a longer OS than the non-CHB group both before IPTW (HR=0.55, 95% CI=0.33–0.92, log-rank p=0.02) and after IPTW (HR=0.53, 95% CI=0.32–0.99, log-rank p=0.02). Although liver-related deaths did not occur in the non-CHB group, two deaths occurred in the CHB group due to hepatocellular carcinoma and acute liver failure, respectively. 
		                        		
		                        			Conclusions
		                        			Our findings indicate that HBV-associated DLBCL patients receiving antiviral treatment have significantly longer TTP and OS after R-CHOP treatment than HBV-unassociated DLBCL patients.

		                        			 Objective:
		                        			Dysphagia is a common clinical condition characterized by difficulty in swallowing. It is sub-classified into oropharyngeal dysphagia, which refers to problems in the mouth and pharynx, and esophageal dysphagia, which refers to problems in the esophageal body and esophagogastric junction. Dysphagia can have a significant negative impact one’s physical health and quality of life as its severity increases. Therefore, proper assessment and management of dysphagia are critical for improving swallowing function and preventing complications. Thus a guideline was developed to provide evidence-based recommendations for assessment and management in patients with dysphagia. 
		                        		
		                        			Methods:
		                        			Nineteen key questions on dysphagia were developed. These questions dealt with various aspects of problems related to dysphagia, including assessment, management, and complications. A literature search for relevant articles was conducted using Pubmed, Embase, the Cochrane Library, and one domestic database of KoreaMed, until April 2021. The level of evidence and recommendation grade were established according to the Grading of Recommendation Assessment, Development and Evaluation methodology. 
		                        		
		                        			Results:
		                        			Early screening and assessment of videofluoroscopic swallowing were recommended for assessing the presence of dysphagia. Therapeutic methods, such as tongue and pharyngeal muscle strengthening exercises and neuromuscular electrical stimulation with swallowing therapy, were effective in improving swallowing function and quality of life in patients with dysphagia. Nutritional intervention and an oral care program were also recommended. 
		                        		
		                        			Conclusion
		                        			This guideline presents recommendations for the assessment and management of patients with oropharyngeal dysphagia, including rehabilitative strategies.

		                        			PURPOSE: Lung cancers presenting as subsolid nodule commonly have peripheral location, making the cancer-pleura relationship noteworthy. We aimed to evaluate the effect of pleural attachment and/or indentation on visceral pleural invasion (VPI) and recurrence-free survival. MATERIALS AND METHODS: Patients who underwent curative resection of lung cancer as subsolid nodules from April 2007 to January 2016 were retrospectively evaluated. They were divided into four groups according to their relationship with the pleura. Clinical, radiographical, and pathological findings were analyzed. RESULTS: Among 404 patients with malignant subsolid nodule, 120 (29.7%) had neither pleural attachment nor indentation, 26 (6.4%) had attachment only, 117 (29.0%) had indentation only, and 141 (34.9%) had both. VPI was observed in nodules of 36 patients (8.9%), but absent in nonsolid nodules and in those without pleural attachment and/or indentation. Compared to subsolid nodules with concurrent pleural attachment and indentation, those with attachment only (odds ratio, 0.12; 95% confidence interval [CI], 0.02 to 0.98) and indentation only (odds ratio, 0.10; 95% CI, 0.03 to 0.31) revealed lower odds of VPI. On subgroup analysis, the size of the solid portion was associated with VPI among those with pleural attachment and indentation (p=0.021). Such high-risk features for VPI were associated with earlier lung cancer recurrence (adjusted hazard ratio, 3.31; 95% CI, 1.58 to 6.91). CONCLUSION: Concurrent pleural attachment and indentation are risk factors for VPI, and the odds increase with larger solid portion in subsolid nodules. Considering the risk of recurrence, early surgical resection could be encouraged in these patients.

		                        			PURPOSE: This study aimed to identify the view of life and death among ICU nurses and to analyze the problems related to end-of-life care in the current ICUs. METHODS: A descriptive study design was used. The participants were 975 nurses working in the intensive care units of 16 general hospitals. Using a descriptive survey design, data were collected from August to December in 2016 and were analyzed using descriptive statistics, t-test, ANOVA, correlation analysis, and multiple regression analysis. RESULTS: As a result of a correlation analysis of the data, Death perception had a significant positive correlation with EOL of nursing attitudes(r=.100, p=.002), and negative correlation with EOL stress care(r=−.221, p= < .001). The regression model explained for individual characteristics in the model, age(β=.126, p < .001) and death perception(β=.182, p < .001), Satisfaction of the EOL care(β=.173, p < .001), Healing training needs on the EOL(β=−.144, p < .001) were the most influential factors for EOL stress. CONCLUSION: Results reveal that ICU nurses have a moderate level of EOL stress, and that individual, age, death perception, Satisfaction of the EOL care, Healing traning needs on the EOL relevant in ICU nurses' EOL stress. Programs or interventions to reduce EOL stress and to should be developed taking into account these multidimensional factors.

		                        			PURPOSE: This study examined the availability of the age shock index in an assessment of high risk patients with acute cholecystitis in an emergency department. METHODS: Consecutive data of patients who presented to the emergency department with acute cholecystitis during the period, January 2012 and March 2017, were reviewed retrospectively. Univariate and multivariate analyses were performed to determine the relationship between the severity of acute cholecystitis and the clinical factors. RESULTS: A total of 242 patients with acute cholecystitis were included in this study. From univariate analyses, age, Murphy's sign, symptom duration, heart rate, respiratory rate, age shock index, hypertension, diabetes, leukocytes, C-reactive protein and blood urea nitrogen were found to be related to the severity of acute cholecystitis. From multivariate analysis, the symptom duration (OR, 4.271; 95% CI, 2.672-6.827), respiratory rate (OR, 1.482; 95% CI, 1.189-1.847), age shock index (OR, 1.609; 95% CI, 1.060-2.442, 10-point interval), leukocytes (OR, 1.283; 95% CI, 1.156-1.424), and diabetes (OR, 4.590; 95% CI, 1.507-13.976) had a positive relationship with the severity of acute cholecystitis. CONCLUSION: The age shock index, which is calculated easily using the patient's age, heart rate, and systolic blood pressure, can be a predicting factor of severe acute cholecystitis in an emergency department.

		                        			PURPOSE: The purpose of this study is to investigate nurses' role conflict and intention to remain and to identify factors that may influence this intention. METHODS: Data were collected from 172 nurses in a 600-plus bed hospital on nurses' intention to remain, which included 47 items and nurses' role conflict, which included 82 items from a self-reported questionnaire. Data were analyzed by descriptive statistics and stepwise multiple regression using SPSS 22.0. RESULTS: The mean of the role conflict frequency was 2.71(±.39) and the mean severity was 2.86 (±.47). The most significant item among the items of intention to remain was “a nurse's job is to help people.” The intention to remain employed showed a significant difference in the duration of desired working period and subjective job satisfaction. The subjective job satisfaction of nurses was the most influential variable as a factor affecting the intention to remain, followed by frequency of role conflict in nursing practice. CONCLUSION: These results suggest that inadequate nursing environments in nursing practice require improvement and support the idea that nurses with positive attitudes of the nursing organization and theirs leaders reduce nurses' related fatigue.

		                        			Hemangioma of the heart, presenting as a primary cardiac tumor is extremely rare; it accounts for approximately 2% of all primary resected heart tumors. In our patient, the tumor was located in the orifice of the right lower pulmonary vein. Few cases of cardiac hemangiomas have been reported to arise from the left atrial (LA) wall. Left atrial hemangiomas, especially those attached to the LA wall, may be erroneously diagnosed as myxomas. Cardiac hemangioma is a rare disease; furthermore, a tumor arising from the LA wall and misconceived as a myxoma is extremely rare. We removed a mass misdiagnosed as a myxoma; it was pathologically confirmed to be a cardiac capillary hemangioma. Therefore, we report a rare case of a cardiac hemangioma misconceived as a myxoma; the tumor was removed successfully.

		                        			Endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric and esophageal cancer. Compared to endoscopic mucosal resection, ESD has the advantage of enabling en bloc removal of tumors regardless of their size. However, ESD can result in a large artificial ulcer, which may lead to a considerable deformity. Circumferential mucosal defects of more than three-fourths the esophageal circumference, long longitudinal mucosal defects (>30 mm), and lesions in the upper esophagus are significant risk factors for the development of post-ESD strictures of the esophagus. In the stomach, a circumferential mucosal defects more than three-fourths in extent and longitudinal mucosal defects >5 cm are risk factors of post-ESD stricture. If scheduled early, regular endoscopic balloon dilation is effective in controlling and preventing post-ESD stricture. Moreover, intralesional steroid injections or oral steroids can achieve remission of dysphagia or reduce the need for repeated endoscopic balloon dilation. However, further study is needed to improve the prevention of stricture formation.
