Abstract
OBJECTIVE Megestrol acetate (MA) is used to manage anorexia and cachexia in patients with advanced cancer. This study investigated the prescription patterns of MA in patients with metastatic gastric cancer, as well as evaluated its impact on survival outcomes and the incidence of venous thromboembolism (VTE). METHODS A Health Insurance Review and Assessment (HIRA) service database was used to investigate differences in baseline characteristics, survival, and the incidence of VTE according to MA prescription patterns (i.e., prescription vs. no prescription) in patients diagnosed with metastatic gastric cancer from July 2014 to December 2015. RESULTS A total of 1938 patients were included in this study. In total, 65% of the patients were prescribed MA. Older age, treatment in tertiary hospitals, and palliative chemotherapy were statistically significant predictive factors for MA prescription. Continuous prescription of MA was observed in 37% of patients. There was no statistically significant difference in survival between the MA and non-MA prescription groups on multivariate analysis. Among the 1427 patients included in the analysis for VTE incidence, 4.3% and 2.9% were diagnosed with VTE during the follow-up period in the MA and non-MA prescription groups, respectively. However, there was no statistically significant difference in VTE diagnosis between the groups on multivariate analysis. CONCLUSION MA is commonly prescribed for metastatic gastric cancer, especially in elderly patients and those undergoing palliative chemotherapy, without significantly affecting survival or VTE risk.

Abstract
OBJECTIVE We examined age-varying associations between young adult simultaneous alcohol and marijuana/cannabis use (SAM) and heavy episodic drinking (HED) and positive and negative affect to inform harm reduction efforts. METHODS Young adults reporting past-year alcohol use (n = 556; ages 19-25) were recruited in a state where alcohol and nonmedical cannabis use was legal for those 21 +. Participants provided 24 repeated monthly assessments. Among those reporting past-month cannabis use on at least one survey, logistic time-varying effect models estimated (1) the age-varying prevalence of and associations between past-month SAM and HED and (2) age-varying unique associations of affect with SAM and HED. RESULTS There was a positive age-varying association between HED and SAM over time that was highest at age 19 (OR = 7.56), decreased until age 20.7 (OR = 3.39), increased until age 23.0 (OR = 4.85), and decreased until the association became non-significant by age 25. Negative affect was positively associated with SAM from ages 20.7 to 23.0, peaking at age 21.8 (OR = 1.36). Positive affect was positively associated with HED from ages 19.4 to 20.4 (peak OR = 1.25) and ages 22.5 to 24.5 (peak OR = 1.38). In contrast, positive affect was not uniquely associated with SAM nor negative affect with HED across ages 19-25. CONCLUSIONS While HED and SAM were positively associated throughout young adulthood and interventions could target them in tandem, their associations with affect suggest differential etiologic processes. Preventive intervention and harm reduction efforts should attend to psychological context in which these behaviors occur.

Abstract
RATIONALE Epiglottic retroversion is the abnormal movement of the epiglottis to the rima glottis, resulting in blockage of inspiratory airflow. Acute upper airway obstruction caused by epiglottic retroversion can lead to sudden respiratory failure. Epiglottic retroversion has occasionally been reported in horses and dogs; however it is extremely rare in humans. Herein, we report a case of epiglottic retroversion causing recurrent upper airway obstruction in human. PATIENT CONCERNS We present the case of a 74-year-old man who was diagnosed with epiglottic retroversion without evidence of epiglottis. The patient presented with recurrent episodes of abnormal breathing sounds and dyspnea. Inspiratory stridor was evident whenever the patient experienced dyspnea. DIAGNOSIS Epiglottic retroversion was diagnosed as the cause of upper airway obstruction using fiber-optic bronchoscopy. INTERVENTIONS The patient underwent tracheostomy to prevent acute respiratory failure because the recurrent episodes of stridor and dyspnea did not improve. OUTCOMES The episodic dyspnea and oxygen desaturation did not relapse after tracheostomy and he could be discharged home. LESSONS This case highlights the importance of considering epiglottic retroversion as a cause of acute upper airway obstruction.

Abstract
BACKGROUND Despite the significant impact of multi-drug-resistant bacteraemia, especially extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-E) and carbapenem-resistant Enterobacterales (CRE), the burden of disease has not been investigated thoroughly. AIM To evaluate the clinical outcomes and socio-economic burden of ESBL-E and CRE bacteraemia nationwide in the Republic of Korea. METHODS A search was undertaken for all cases of ESBL-E and CRE bacteraemia and matched controls in 10 hospitals in the Republic of Korea over 6 months. Patients with ESBL-E or CRE bacteraemia were classified as the R group, and matched controls with antibiotic-susceptible bacteraemia and without infection were classified as the S and N groups, respectively. Patients' clinical data were collected, and the economic burden was estimated based on medical expenses, loss of productivity and total costs. FINDINGS In total, 795 patients were identified, including 265 patients with ESBL-E or CRE bacteraemia and their matched controls. The mean total length of stay for patients with ESBL-E and CRE in the R group was 1.53 and 1.90 times that of patients in the S group, respectively. The 90-day mortality rates for ESBL-E in the R and S groups were 12.1% and 5.6%, respectively, and the corresponding figures for CRE were 28.6% and 12.0%. There were significant differences in the total costs between the R, S and N groups for both ESBL-E and CRE (ESBL-E: $11,151 vs $8712 vs $6063, P=0.004; CRE: $40,464 vs $8748 vs $7279, P=0.024). CONCLUSION The clinical and economic burden imposed by ESBL-E or CRE bacteraemia was extremely high. These findings suggest that efforts to control resistant bacteraemia are necessary to reduce this burden.

Abstract
BACKGROUND AND OBJECTIVE Cerebral vascular diseases are among the most burdensome diseases faced by society. However, investigating the pathophysiology of diseases as well as developing future treatments still relies heavily on expensive in-vivo and in-vitro studies. The generation of realistic, patient-specific models of the cerebrovascular system capable of simulating hemodynamics and perfusion promises the ability to simulate diseased states, therefore accelerating development cycles using in silico studies and opening opportunities for the individual assessment of diseased states, treatment planning, and the prediction of outcomes. By providing a patient-specific, anatomically detailed and validated model of the human cerebral vascular system, we aim to provide the basis for future in silico investigations of the cerebral physiology and pathology. METHODS In this retrospective study, a processing pipeline for patient-specific quantification of cerebral perfusion was developed and applied to healthy individuals and a stroke patient. Major arteries are segmented from 3T MR angiography data. A synthetic tree generation algorithm titled tissue-growth based optimization (GBO)1 is used to extend vascular trees beyond the imaging resolution. To investigate the anatomical accuracy of the generated trees, morphological parameters are compared against those of 7 T MRI, 9.4 T MRI, and dissection data. Using the generated vessel model, hemodynamics and perfusion are simulated by solving one-dimensional blood flow equations combined with Darcy flow equations. RESULTS Morphological data of three healthy individuals (mean age 47 years ± 15.9 [SD], 2 female) was analyzed. Bifurcation and physiological characteristics of the synthetically generated vessels are comparable to those of dissection data. The inability of MRI based segmentation to resolve small branches and the small volume investigated cause a mismatch in the comparison to MRI data. Cerebral perfusion was estimated for healthy individuals and a stroke patient. The simulated perfusion is compared against Arterial-Spin-Labeling MRI perfusion data. Good qualitative agreement is found between simulated and measured cerebral blood flow (CBF)2. Ischemic regions are predicted well, however ischemia severity is overestimated. CONCLUSIONS GBO successfully generates detailed cerebral vascular models with realistic morphological parameters. Simulations based on the resulting networks predict perfusion territories and ischemic regions successfully.

Abstract
Objective While a rushed operation can omit essential procedures, prolonged operative time results in higher morbidity. Nevertheless, the optimal operative time range remains uncertain. This study aimed to estimate the ideal operative time range and evaluate its applicability in laparoscopic cancer surgery. Methods A prospectively collected multicenter database of 397 patients who underwent laparoscopic distal gastrectomy were retrospectively reviewed. The ideal operative time range was statistically calculated by separately analyzing the operative time of uneventful surgeries. Finally, intraoperative and postoperative outcomes were compared among the shorter, ideal, and longer operative time groups. Results The statistically calculated ideal operative time was 135.4-165.4 min. The longer operative time (LOT) group had a lower rate of uneventful, perfect surgery than the ideal or shorter operative time (IOT/SOT) group (2.8% vs. 8.8% and 2.2% vs. 13.4%, all P<0.05). Longer operative time increased bleeding, postoperative morbidities, and delayed diet and discharge (all P<0.05). Particularly, an uneventful, perfect surgery could not be achieved when the operative time exceeded 240 min. Regardless of ideal time range, SOT group achieved the highest percentage of uneventful surgery (13.4%), which was possible by surgeon's ability to retrieve a higher number of lymph nodes and perform ≥150 gastrectomies annually. Conclusions Operative time longer than the ideal time range (especially ≥240 min) should be avoided. If the essential operative procedure were faithfully conducted without compromising oncological safety, an operative time shorter than the ideal range leaded to a better prognosis. Efforts to minimize operative time should be attempted with sufficient surgical experience.

Abstract
Purpose To identify weight loss prediction models by validating previous models using weight loss success criteria. Materials and Methods Patients with morbid obesity from 4 hospitals were retrospectively analyzed between Jan 2019 and 2022. Preoperative demographics, postoperative data, and 1-year follow-up weight loss outcomes were compared between 2 groups who underwent laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). Additionally, the predictive factors for the success of excess weight loss (EWL) (>50%) and total weight loss (TWL) (>25%) were analyzed. Results Of the 162 patients, 137 were enrolled during the study period, 75 underwent LSG, and 62 underwent LRYGB. The >50% EWL and >25% TWL 1 year after surgery were 61.3% and 43.1%, respectively. Diabetes mellitus medication use was reduced in 94.8% of patients with type 2 diabetes mellitus. Male sex and body mass index (BMI) were independent risk factors for successful weight loss (SWL) or >50% EWL (odds ratio [OR] for BMI 0.830, 95% confidence interval [CI] 0.764-0.902), whereas achieving >25% TWL was not affected by sex or BMI (OR for BMI 1.010, 95% CI 0.957-1.065). External validation of the prediction models showed an acceptable range of accuracy (adjusted R2 66.5-71.3%). Conclusion LSG and LRYGB are feasible and effective bariatric procedures for SWL in Korean patients with morbid obesity. The TWL model was a more appropriate criterion than EWL, and weight loss prediction models may help assess the 1-year outcomes of bariatric surgery.

Abstract
Purpose Comorbidities of a principal diagnosis have varying impacts on disease and require different management depending on the onset timing. This study investigated the usefulness of present-on-admission (POA), specifically focusing on decubitus ulcers, delirium, and hypokalemia, as an indicator of healthcare quality. Patients and Methods We analyzed patient discharge data for 14 years from 2006 to 2019 using Korean National Hospital Discharge In-Depth Injury Survey (KNHDIS). Results Out of 3,231,731 discharged patients, 19,871 had secondary diagnosis codes for decubitus ulcers (n=10,390, 52.3%), delirium (n=6103, 30.7%), or hypokalemia (n=3378, 17.0%). Analysis of patients with secondary diagnoses of decubitus ulcers, delirium, or hypokalemia revealed notable differences in demographics, including gender distribution, mean age, admission route, insurance type, surgical intervention rates, mortality rates, and length of stay (LOS). Among patients with one of the top 20 principal diagnoses, those with secondary diagnoses of decubitus ulcers, delirium, or hypokalemia exhibited higher odds of surgery, increased mortality risks, and longer LOS compared to those without these secondary diagnoses. Conclusion All three of these diseases commonly occur postoperatively or during treatment and thus should be designated as potentially preventable complications that require special attention, and should also be considered as quality-of-care indicators.

Abstract
Abdominal aortic aneurysm can exhibit transitional flow characteristics in laminar flow regimes. To report transitional flow characteristics, we examined the convergence of phase-averaged solutions by executing blood flow simulations of a patient-specific abdominal aortic aneurysmal model for 257 cardiac cycles with periodic, pulsatile boundary conditions. The phase-averaged solutions were computed by averaging the solutions over various numbers of cardiac cycles and compared against the ones averaged over 124 cycles. The phase-averaged solutions reported small differences when they were averaged over a large number of cardiac cycles. The instantaneous solutions, however, failed to exhibit fluctuations reported in the phase-averaged solutions. To study transitional blood flows in the aneurysmal region, we need to report phase-averaged solutions as they exhibit nonperiodic, disturbed flow characteristics. Additionally, when reporting phase-averaged solutions, it is preferred to compute an average over a large number of cardiac cycles to be able to represent flow structures of the converged phase-averaged solutions.

Abstract
To overcome the limitations of laparoscopic surgery, robotic systems have been commonly used in the era of minimally invasive surgery despite their high cost. However, the articulation of instruments can be achieved without a robotic system at lower cost using articulating laparoscopic instruments (ALIs). Between May 2021 and May 2022, perioperative outcomes following laparoscopic gastrectomy using ALIs versus robotic gastrectomy were compared. A total of 88 patients underwent laparoscopic gastrectomy using ALIs, while 96 underwent robotic gastrectomy. Baseline characteristics were similar between the groups except for a higher proportion of patients with a medical history in the ALI group (p = 0.013). Clinicopathologic and perioperative outcomes were not significantly different between the groups. However, the operation time was significantly shorter in the ALI group (p = 0.026). No deaths occurred in either group. In conclusion, laparoscopic gastrectomy using ALIs was associated with comparable perioperative surgical outcomes and a shorter operation time compared to robotic gastrectomy in this prospective cohort study.

Abstract
BACKGROUND Currently, the reported parameters that predict the resolution of symptoms after surgery are largely subjective and unreliable. Considering that fundoplication rebuilds the structural integrity of the lower esophageal sphincter (LES), the authors focused on searching for objective and quantitative predictors for the resolution of symptoms based on the anatomical issues and whether an antireflux barrier can be well established or not. MATERIALS AND METHODS The authors reviewed the prospectively collected data of 266 patients with gastroesophageal reflux disease (GERD) who had undergone laparoscopic Nissen fundoplication (LNF). All patients were diagnosed with GERD using preoperative esophagogastroduodenoscopy, 24-h ambulatory esophageal pH monitoring, and high-resolution esophageal manometry. The patients received GERD symptom surveys using the validated Korean Antireflux Surgery Group questionnaire twice: preoperatively and 3 months after the surgery. RESULTS After excluding patients with insufficient follow-up data, 152 patients were included in the analysis. Multivariate logistic regression analyses revealed that a longer length of the LES and lower BMI determined better resolution of typical symptoms after LNF (all P <0.05). Regarding atypical symptoms, higher resting pressure of LES and DeMeester score greater than or equal to 14.7 were associated with better resolution after the surgery (all P <0.05). After LNF, typical symptoms improved in 34 out of 37 patients (91.9%) with a length of LES >greater than .05 cm, BMI less than 23.67 kg/m 2 , and atypical symptoms were resolved in 16 out of 19 patients (84.2%) with resting pressure of LES greater than or equal to 19.65 mm Hg, DeMeester score greater than or equal to 14.7. CONCLUSION These results show that the preoperative length and resting pressure of LES is important in the objective prediction of symptom improvement after LNF.

Abstract
Cyberbullying among children is increasing every year, leading to serious public health problems. Victims suffer serious aftereffects such as depression and suicidal ideation; therefore, early and appropriate psychological intervention and the role of schools are emphasized. This study investigated the effects of school sandplay group therapy (SSGT) on children affected by cyberbullying. This study was designed as a parallel-group non-randomized controlled trial. The study subjects were 139 elementary school students (mean age 11.35 years; standard deviation, 0.479; age range 12-13 years) residing in Cheonan City, Korea, who were assigned to the intervention and comparison groups. The intervention group received 10 sessions of therapy on a weekly basis, for 40 minutes per session. No therapy was administered in the control group. The effectiveness of the intervention was assessed using the Children Depression Inventory, Suicidal Ideation Questionnaire-Junior, and Rosenberg Self-Esteem Scale. The assessment for the comparison group was performed concurrently with that of the intervention group. Data were analyzed using multivariate analysis of variance. In this study, the SSGT group showed a significant decrease in depression and suicidal ideation compared to the control group after sandplay group therapy (SGT), and a significant increase in self-esteem. It was confirmed that SSGT can mitigate the negative consequences of cyberbullying and strengthen protective factors. This suggests that the SSGT can be successfully used for crisis counseling.

Abstract
BACKGROUND Crohn's disease (CD) is associated with altered body composition, affecting clinical outcomes. We evaluated the impact of biologics on body composition in CD patients. METHODS This multicenter longitudinal study across four Korean university hospitals conducted from January 2009 to August 2021 retrospectively reviewed data of CD patients with abdominal computed tomography (CT) before and after the biologic treatment. Skeletal muscle area (SMA), visceral fat area (VFA), and subcutaneous fat area (SFA) of the third lumbar vertebra (L3) on CT were measured. Myopenia was defined as L3 skeletal muscle index (SMI) of < 49 and < 31 cm2/m2 for men and women, respectively. RESULTS Among 112 participants, 79 (70.5%) had myopenia. In the myopenia group, all body composition parameters were significantly increased after the biologic treatment: SMI (37.68 vs. 39.40 cm2/m2; P < 0.001), VFA (26.12 vs. 54.61 cm2; P < 0.001), SFA (44.29 vs. 82.42 cm2; P < 0.001), while no significant differences were observed in the non-myopenia group. In multivariate analysis, penetrating CD (hazard ratio, 5.40; P = 0.020) was the independent prognostic factor for surgery. Operation-free survival rate tended to decrease in the myopenia group (Log-rank test, P = 0.090). CONCLUSIONS Biological agents can increase all body composition parameters in CD patients with myopenia. These patients are more likely to experience surgery.

Abstract
Purpose Near-infrared fluorescence imaging has been recently applied in the field of hepatobiliary surgery. Our objective was to apply blue-light fluorescence cholangiography during laparoscopic surgery. Therefore, we designed a preclinical study to evaluate the feasibility of using blue-light fluorescence for cholangiography in a porcine model. Methods Five millimeters of sodium fluorescein (SF) solution was administered into the gallbladder of 20 male 3-way crossbred (Landrace × Yorkshire × Duroc) pigs in laparoscopic approach. The biliary tree was observed under blue light (a peak wavelength of 450 nm) emitted from a commercialized light-emitting diode (LED) light source (XLS1 extreme, Chammed). Results In 18 of 20 porcine models, immediately after SF solution was administered into the gallbladder, it was possible to visualize the biliary tree under blue light emitted from the LED light source. Conclusion This study provided a preclinical basis for using blue-light fluorescence cholangiography using SF in laparoscopic surgery. The clinical feasibility of blue-light fluorescence imaging techniques for laparoscopic cholecystectomy remained to be demonstrated.

Abstract
BACKGROUND Isolating patients infected or colonized with vancomycin-resistant enterococci (VRE) in a private room or cohort room to prevent hospital transmission is controversial. AIM To evaluate the effect of a relaxed isolation policy for VRE-infected or colonized patients on healthcare-associated (HA) VRE bacteraemia in an acute care hospital with a predominantly shared-room setting. METHODS The incidence of HA VRE bacteraemia was compared during a private isolation era (October 2014-September 2017), a cohort isolation era (October 2017-June 2020), and a no isolation era (July 2020-June 2022). Using Poisson regression modelling, an interrupted time-series analysis was conducted to analyse level changes and trends in incidences of HA VRE bacteraemia for each era. FINDINGS The proportion of VRE-infected or -colonized patients staying in shared rooms increased from 18.3% in the private isolation era to 82.6% in the no isolation era (P < 0.001). There was no significant difference in the incidences of HA VRE bacteraemia between the private isolation era and the cohort isolation era (relative risk: 1.01; 95% confidence interval: 0.52-1.98; P = 0.977) or between the cohort isolation era and the no isolation era (0.99; 0.77-1.26; P = 0.903). In addition, there was no significant slope increase in the incidence of HA VRE bacteraemia between any of the eras. CONCLUSION In a hospital with predominantly shared rooms, the relaxation of isolation policy did not result in increased HA VRE bacteraemia, when other infection control measures were maintained.

Abstract
Situs inversus totalis (SIT) is a rare anatomical condition, where all the viscera appear in its reverse position. Although minimally invasive surgery has evolved to achieve totally laparoscopic gastrectomy for gastric cancer patients with SIT, it is difficult to perform lymphadenectomy in such a transposed anatomical condition. Recently, we performed a single-port laparoscopic total gastrectomy (SPTG) for gastric cancer in a patient with SIT. No postoperative complications or dietary problems were observed. Based on this experience, we are to design a safe strategy to perform D2 lymphadenectomy during SPTG in patients with SIT.

Abstract
BACKGROUND Optimal length of biliopancreatic (BP) and Roux limb in Roux-en-Y gastric bypass (RYGB) for improved glycemic control are not known. PURPOSE To investigate how the lengths of the BP and Roux limbs in RYGB differentially affect postoperative glycemic outcomes in patients with type 2 diabetes. DATA SOURCES We conducted a systematic literature search using the PubMed, Embase, and the Cochrane Library databases. STUDY SELECTION We included studies that reported glycemic outcomes after RYGB and lengths of the BP and Roux limbs. DATA EXTRACTION A total of 28 articles were included for data extraction. Glycemic outcomes after RYGB were assessed on the basis of two definitions: remission and improvement. DATA SYNTHESIS We categorized the included studies into four groups according to the BP and Roux limb lengths. The type 2 diabetes remission/improvement rates were as follows: long BP-long Roux group 0.80 (95% CI 0.70-0.90)/0.81 (0.73-0.89), long BP-short Roux group 0.76 (0.66-0.87)/0.82 (0.75-0.89), short BP-long Roux group 0.57 (0.36-0.78)/0.64 (0.53-0.75), and short BP-short Roux group 0.62 (0.43-0.80)/0.53 (0.45-0.61). Meta-regression analysis also showed that a longer BP limb resulted in higher postoperative type 2 diabetes remission and improvement rates, whereas a longer Roux limb did not. There was no significant difference or heterogeneity in baseline characteristics, including diabetes-related variables, among the four groups. LIMITATIONS Not all included studies were randomized controlled trials. CONCLUSIONS Longer BP limb length led to higher rates of type 2 diabetes remission and improvement by 1 year after RYGB in comparisons with the longer Roux limb length.

Abstract
Langerhans cell histiocytosis (LCH) is reported less frequently in adults than in children. The most common site of involvement in adults is the bone, accounting for 30-50% of cases. The gastrointestinal tract is very rare, accounting for approximately 2%. We present a case of Langerhans cell histiocytosis that simultaneously invaded multiple organs, including the stomach and colon, in an adult. A 37-year-old woman with no underlying disease complained of chest discomfort and a palpable right submandibular mass. A right Level II neck mass and mediastinal LN enlargement were confirmed on the pharynx and chest CT scan. Multiple subepithelial masses with central ulceration and erosion were observed in the corpus and fundus on the esophagogastroduodenoscopy and in the right colon on the colonoscopy. The histopathology findings were the same in each tissue biopsied from the stomach, colon, and right neck lymph nodes. Langerhans cells with classical reniform nuclei and prominent eosinophils invaded the normal glands, and S100 and CD1a were positive in the immunohistochemical stain. Gastrointestinal involvement of LCH in adults is rare, asymptomatic,and can involve multiple digestive organs simultaneously, so upper endoscopy and colonoscopy should be considered for a diagnosis.

Abstract
Background Bismuth quadruple (BQ) therapy is known to have poor patient compliance and a complex dosing method, and no appropriate third‐line regimen exists if second‐line BQ therapy fails. In Korea, some alternative regimens have shown unsatisfactory eradication rates. Therefore, we investigated the success rates of the second‐line moxifloxacin–rifabutin triple (MRT) regimen and compared it with BQ regimen in subgroup analysis of peptic ulcer patients. Materials and Methods This study was a retrospective study of 71 patients who underwent a second‐line MRT for Helicobacter pylori after failing to clarithromycin triple regimen. To compare the eradication rate in gastric ulcer patients, 51 patients in the MRT group and 132 patients in BQ group were included. After age and sex propensity matching, 45 patients were included in each group (the alpha value and power were set at 0.05% and 77%, respectively). Results The eradication rate in the MRT group was 69.0% (49/71) in the intention‐to‐treat (ITT) analysis and 77.8% (49/63) in the per‐protocol (PP) analysis. These were significantly lower than the eradication rate in the BQ group (82.5%, p = 0.019 in the ITT analysis; 89.3%, p = 0.022 in the PP analysis). In subgroup analysis of peptic ulcer patients, the success rate of BQ group was significantly higher than that of MRT group in both ITT and PP populations (81.8% (108/132) vs. 60.8% (31/51) in the ITT populations, p = 0.004; and 90.0% (108/120) vs. 72.1% (31/43) in the PP populations, p = 0.010). Among the 14 patients with MRT therapy failure, 10 were eradicated with BQ as the third‐line regimen. The eradication rate of the third‐line BQ after the second‐line MRT failure was 90.0% (9/10). Conclusion Second‐line MRT therapy was not as effective as BQ therapy, so it should be considered for limited use only when BQ is not available.

Abstract
The desire to enhance the efficiency of organic light-emitting devices (OLEDs) has driven to the investigation of advanced materials with fascinating properties. In this work, the efficiency of top-emission OLEDs (TEOLEDs) is enhanced by introducing ampicillin microstructures (Amp-MSs) with dual phases (α-/β-phase) that induce photoluminescence (PL) and electroluminescence (EL). Moreover, Amp-MSs can adjust the charge balance by Fermi level (EF ) alignment, thereby decreasing the leakage current. The decrease in the wave-guided modes can enhance the light outcoupling through optical scattering. The resulting TEOLED demonstrates a record-high external quantum efficiency (EQE) (maximum: 68.7% and average: 63.4% at spectroradiometer; maximum: 44.8% and average: 42.6% at integrating sphere) with a wider color gamut (118%) owing to the redshift of the spectrum by J-aggregation. Deconvolution of the EL intensities is performed to clarify the contribution of Amp-MSs to the device EQE enhancement (optical scattering by Amp-MSs: 17.0%, PL by radiative energy transfer: 9.1%, and EL by J-aggregated excitons: 4.6%). The proposed TEOLED outperforms the existing frameworks in terms of device efficiency.

Abstract
Background: Bariatric or metabolic surgery is a safe and effective intervention for patients with obesity at higherrisk. In 2019, after the reimbursement in Korea, the number of metabolic surgery cases has rapidly increased. We aimed to introduce the current metabolic surgery concepts.Current Concepts: Patients with a body mass index (BMI) of ≥35 kg/m2 without coexisting medical problems and those with a BMI of ≥30 kg/m2 and ≥1 severe obesity-related complication remediable by weight loss could be considered as the candidates for metabolic surgery. The standardized and effective procedures are adjustable gastric banding, sleeve gastrectomy, Roux-en-Y gastric bypass, and biliopancreatic diversion with duodenal switch. The decision on bariatric procedures should be based on the characteristics of patients considering the effectiveness and anticipated complications.Discussion and Conclusion: Metabolic surgery was shown to induce greater weight loss, better control of comorbidities, such as type 2 diabetes, hypertension, and dyslipidemia, and more significant decrease in death compared to that of the nonsurgical approach. Postoperatively, a comprehensive approach consisting of psychosocial, behavioral, nutritional, and pharmacological aspects should be performed to amplify and maintain the effectiveness of metabolic surgery.

Abstract
Coronavirus disease 2019 (COVID-19) is the disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2; SC2), which has caused a worldwide pandemic with striking morbidity and mortality. Evaluation of SC2 strains demonstrated impressive genetic variability, and many of these viral variants are now defined as variants of concern (VOC) that cause enhanced transmissibility, decreased susceptibility to antibody neutralization or therapeutics, and/or the ability to induce severe disease. Currently, the delta (δ) and omicron (ο) variants are particularly problematic based on their impressive and unprecedented transmissibility and ability to cause breakthrough infections. The delta variant also accumulates at high concentrations in host tissues and has caused waves of lethal disease. Because studies from our laboratory have demonstrated that chitinase 3-like-1 (CHI3L1) stimulates ACE2 and Spike (S) priming proteases that mediate SC2 infection, studies were undertaken to determine if interventions that target CHI3L1 are effective inhibitors of SC2 viral variant infection. Here, we demonstrate that CHI3L1 augments epithelial cell infection by pseudoviruses that express the alpha, beta, gamma, delta, or omicron S proteins and that the CHI3L1 inhibitors anti-CHI3L1 and kasugamycin inhibit epithelial cell infection by these VOC pseudovirus moieties. Thus, CHI3L1 is a universal, VOC-independent therapeutic target in COVID-19.

Abstract
BACKGROUND The most common site of paragonimiasis is in the lungs. The migratory route passes through the duodenal wall, peritoneum, and diaphragm to the lungs; thus, the thoracic cavity and central nervous system, as well as the liver, intestine, and abdominal cavity may be involved. Here, we present a case of intraperitoneal paragonimiasis without other organ involvement, mimicking tuberculous peritonitis.
CASE SUMMARY A 57-year-old man presented with recurrent abdominal pain for 4 wk. Physical examination revealed tenderness in the right lower quadrant. Laboratory findings showed complete blood counts within the normal range without eosinophilia. Multiple reactive lymph nodes and diffuse peritoneal infiltration were noted on abdominal computed tomography (CT). There were no abnormalities on chest CT or colonoscopy. Intraoperative findings of diagnostic laparoscopy for the differential diagnosis of tuberculous peritonitis and peritoneal carcinomatosis included multiple small whitish nodules and an abscess in the peritoneum. Pathological reports confirmed the presence of numerous eggs of Paragonimus westermani (P. westermani). A postoperative serum enzyme-linked immunosorbent assay revealed P. westermani positivity. Persistent and repetitive history-taking led him to retrospectively recall the consumption of freshwater crab. After 3 d of treatment with praziquantel (1800 mg; 25 mg/kg), he recovered from all symptoms.
CONCLUSION In patients who require diagnostic laparoscopy for the differential diagnosis of tuberculous peritonitis and peritoneal carcinomatosis, repetitive history-taking and preoperative serologic antibody tests against Paragonimus may be helpful in diagnosing intraperitoneal paragonimiasis without other organ involvement.

Abstract
Although Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most prevalent bariatric surgical procedures, high-level evidence is scarce regarding the assessment of postoperative nutritional risk in RYGB versus SG. Therefore, we performed a systematic review and meta-analysis to compare the risk of anemia and related micronutrient deficiencies after RYGB and SG. We analyzed 10 randomized controlled trials that compared RYGB and SG with reported incidence of postoperative anemia and/or anemia-related micronutrient deficiencies (iron, vitamin B12 , or folate). There were no significant differences in the risk of postoperative anemia (moderate level of evidence), iron deficiency (high level of evidence), or folate deficiency (moderate level of evidence). Patients undergoing RYGB had a higher risk of postoperative vitamin B12 deficiency than those undergoing SG (relative risk, 1.86; 95% confidence interval, 1.15-3.02; p = 0.012; high level of evidence). Our findings imply that patients undergoing RYGB require more stringent vitamin B12 supplementation and surveillance than those undergoing SG. Additionally, our results may aid patients with high concern for anemia and related micronutrient deficiencies in making informed decisions regarding surgical methods based on nutritional risk.

Abstract
BACKGROUND Obesity can hinder laparoscopic procedures and impede oncological safety during laparoscopic cancer surgery. Deep neuromuscular block (NMB) reportedly improves laparoscopic surgical conditions, but its oncological benefits are unclear. We aimed to evaluate whether deep NMB improves the oncologic quality of laparoscopic cancer surgery in obese patients. STUDY DESIGN We conducted a double-blinded, parallel-group, randomized, phase 3 trial at 9 institutions in Korea. Clinical stage I and II gastric cancer patients with a BMI at or above 25 kg m -2 were eligible and randomized 1:1 ratio to the deep or moderate NMB groups, with continuous infusion of rocuronium (0.5-1.0 and 0.1-0.5 mg kg -1 h -1, respectively). The primary endpoint was the number of retrieved lymph nodes (LNs). The secondary endpoints included the surgeon's surgical rating score (SRS) and interrupted events. RESULTS Between August 2017 and July 2020, 196 patients were enrolled. Fifteen patients were excluded, and 181 patients were finally included in the study. There was no significant difference in the number of retrieved LNs between the deep (N = 88) and moderate NMB groups (N = 93; 44.6 ± 17.5 vs 41.5 ± 16.9, p = 0.239). However, deep NMB enabled retrieving more LNs in patients with a BMI at or above 28 kg/m2 than moderate NMB (49.2 ± 18.6 vs 39.2 ± 13.3, p = 0.026). Interrupted events during surgery were lower in the deep NMB group than in the moderate NMB group (21.6% vs 36.6%; p = 0.034). The SRS was not influenced by NMB depth. CONCLUSION Deep NMB provides potential oncologic benefits by retrieving more LNs in patients with BMI at or above 28 kg/m2 during laparoscopic gastrectomy.

Abstract
COVID 19 is the disease caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2; SC2) which has caused a world-wide pandemic with striking morbidity and mortality. Evaluation of SC2 strains demonstrated impressive genetic variability and many of these viral variants are now defined as variants of concern (VOC) that cause enhanced transmissibility, decreased susceptibility to antibody neutralization or therapeutics and or the ability to induce severe disease. Currently, the delta (δ) and omicron (o) variants are particularly problematic based on their impressive and unprecedented transmissibility and ability to cause break through infections. The delta variant also accumulates at high concentrations in host tissues and has caused waves of lethal disease. Because studies from our laboratory have demonstrated that chitinase 3-like-1 (CHI3L1) stimulates ACE2 and Spike (S) priming proteases that mediate SC2 infection, studies were undertaken to determine if interventions that target CHI3L1 are effective inhibitors of SC2 viral variant infection. Here we demonstrate that CHI3L1 augments epithelial cell infection by pseudoviruses that express the alpha, beta, gamma, delta or omicron S proteins and that the CHI3L1 inhibitors anti-CHI3L1 and kasugamycin inhibit epithelial cell infection by these VOC pseudovirus moieties. Thus, CHI3L1 is a universal, VOC-independent therapeutic target in COVID 19.

Abstract
While urine-based liquid biopsy has expanded to the analyses of extracellular nucleic acids, the potential of transfer RNA (tRNA) encapsulated within extracellular vesicles has not been explored as a new class of urine biomarkers for kidney injury. Using rat kidney and mouse tubular cell injury models, we tested if extracellular vesicle-loaded tRNA and their m1A (N1-methyladenosine) modification reflect oxidative stress of kidney injury and determined the mechanism of tRNA packaging into extracellular vesicles. We determined a set of extracellular vesicle-loaded, isoaccepting tRNAs differentially released after ischemia-reperfusion injury and oxidative stress. Next, we found that m1A modification of extracellular vesicle tRNAs, despite an increase of the methylated tRNAs in intracellular vesicles, showed little or no change under oxidative stress. Mechanistically, oxidative stress decreases tRNA loading into intracellular vesicles while the tRNA-loaded vesicles are accumulated due to decreased release of the vesicles from the cell surface. Furthermore, Maf1-mediated transcriptional repression of the tRNAs decreases the cargo availability for extracellular vesicle release in response to oxidative stress. Taken together, our data support that release of extracellular vesicle tRNAs reflects oxidative stress of kidney tubules which might be useful to detect ischemic kidney injury and could lead to rebalance protein translation under oxidative stress.

Abstract
BACKGROUND Remdesivir is an anti-viral drug that inhibits RNA polymerase. In 2020, remdesivir was recognized as the most promising therapeutic agents against coronavirus disease 2019 (COVID-19). However, the effects of remdesivir on cancers have hardly been studied. PURPOSE Here, we reported that the anti-carcinogenic effect of remdesivir on SKOV3 cells, one of human ovarian cancer cell lines. RESEARCH DESIGN We anlalyzed the anti-carcarcinogenic effect of remdesivir in SKOV3 cells by performing in vitro cell assay and western blotting. RESULTS WST-1 showed that remdesivir decreased cell viability in SKOV3 cells. Experiments conducted by Muse Cell Analyzer showed that remdesivir-induced apoptosis in SKOV3 cells. We found that the expression level of FOXO3, Bax, and Bim increased, whereas Bcl-2, caspase-3, and caspase-7 decreased by remdesivir in SKOV3 cells. Furthermore, we observed that intracellular reactive oxygen species (ROS) level increased after treatment of remdesivir in SKOV3 cells. Interestingly, cytotoxicity of remdesivir decreased after treatment of N-Acetylcysteine. CONCLUSION Taken together, our results demonstrated that remdesivir has an anti-carcinogenic effect on SKOV3 cells vis up-regulation of reactive oxygen species, which suggests that remdesivir could be a promising reagent for treatment of ovarian cancer.

Abstract
The micronutrient status and optimal monitoring schedule after bariatric surgery have not been sufficiently assessed. This systematic review and meta-analysis investigated the longitudinal changes in micronutrient status after bariatric surgery. PubMed, EMBASE, and Cochrane Library were searched for articles that measured preoperative and postoperative serum micronutrient levels in patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Among guideline-adherent studies, the longitudinal changes in micronutrient status were investigated using weighted mean difference (WMD) using a random-effects model. Among the 82 included studies, the guideline adherence rates for micronutrient supplementation after bariatric surgery did not exceed 20%. In patients supplemented per guidelines, vitamin A significantly decreased after RYGB by -7.54 (95% confidence interval [CI], -10.16 to -4.92) μg/dl at 12-23 months, vitamin E decreased after RYGB by -2.35 (95% CI, -3.65 to -1.05) μg/dl at ≥24 months, and ferritin by -54.93 (95% CI, -77.19 to -32.67] μg/L at ≥24 months after SG, compared with baseline, with moderate level of evidence. Significant decreases in micronutrient levels at certain follow-up intervals in studies with supplementation per guidelines need to be considered to establish a post-bariatric micronutrient monitoring schedule for timely detection and management of micronutrient deficiencies.

Abstract
Indole-3-carbinol (I3C) is a phytochemical that exhibits growth-inhibitory activity against various cancer cells. However, there are limited studies on the effects of I3C on colon cancer cells. In this study, the growth-inhibitory activity of I3C against the human colorectal carcinoma cell line (LoVo) was examined. The results of the 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide, colony formation, and cell counting assays revealed that I3C suppressed the proliferation of LoVo cells. Microscopy and wound-healing analyses revealed that I3C affected the morphology and inhibited the migration of LoVo cells, respectively. I3C induced apoptosis and DNA fragmentation as evidenced by the results of fluorescein isothiocyanate-conjugated annexin V staining and terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick-end labeling assay, respectively. Additionally, I3C arrested the cell cycle at the G0/G1 phase and enhanced the reactive oxygen species levels. Western blotting analysis revealed that treatment with I3C resulted in the activation of apoptotic proteins, such as poly(ADP-ribose) polymerase, caspase-3, caspase-7, caspase-9, Bax, Bim, and p53 in LoVo cells. These results indicate that I3C induces apoptosis in LoVo cells by upregulating p53, leading to the activation of Bax and caspases. Taken together, I3C exerts cytotoxic effects on LoVo cells by activating apoptosis.

Abstract
Stretchable organic light-emitting diodes are ubiquitous in the rapidly developing wearable display technology. However, low efficiency and poor mechanical stability inhibit their commercial applications owing to the restrictions generated by strain. Here, we demonstrate the exceptional performance of a transparent (molybdenum-trioxide/gold/molybdenum-trioxide) electrode for buckled, twistable, and geometrically stretchable organic light-emitting diodes under 2-dimensional random area strain with invariant color coordinates. The devices are fabricated on a thin optical-adhesive/elastomer with a small mechanical bending strain and water-proofed by optical-adhesive encapsulation in a sandwiched structure. The heat dissipation mechanism of the thin optical-adhesive substrate, thin elastomer-based devices or silicon dioxide nanoparticles reduces triplet-triplet annihilation, providing consistent performance at high exciton density, compared with thick elastomer and a glass substrate. The performance is enhanced by the nanoparticles in the optical-adhesive for light out-coupling and improved heat dissipation. A high current efficiency of ~82.4 cd/A and an external quantum efficiency of ~22.3% are achieved with minimum efficiency roll-off.

Abstract
6,8-Diprenylorobol is a natural compound mainly found in Glycyrrhiza uralensis fisch and Maclura tricuspidata, which has been used traditionally as food and medicine in Asia. So far, the antiproliferative effect of 6,8-diprenylorobol has not been studied yet in colon cancer. In this study, we aimed to evaluate the antiproliferative effects of 6,8-diprenylorobol in LoVo and HCT15, two kinds of human colon cancer cells. 6,8-Diprenylorobol inhibited the proliferation of LoVo and HCT15 cells in a dose- and time-dependent manner. A 40 μM of 6,8-diprenylorobol for 72 h reduced both of cell viability under 50%. After treatment of 6,8-diprenylorobol (40 and 60 μM) for 72 h, late apoptotic cell portion in LoVo and HCT15 cells were 24, 70% and 13, 90%, respectively, which was confirmed by checking DNA fragmentation in both cells. Mechanistically, 6,8-diprenylorobol activated p53 and its phosphorylated form (Ser15, Ser20, and Ser46) expression but suppressed Akt and mitogen-activated protein kinases (MAPKs) phosphorylation in LoVo and HCT15 cells. Interestingly, 6,8-diprenylorobol induced the generation of intracellular reactive oxygen species (ROS), which was attenuated with N-acetyl cysteine (NAC) treatment. Compared to the control, 60 μM of 6,8-diprenylorobol caused to increase ROS level to 210% in LoVo and HCT15, which was reduced into 161% and 124%, respectively with NAC. Furthermore, cell viability and apoptotic cell portion by 6,8-diprenylorobol was recovered by incubation with NAC. Taken together, these results indicate that 6,8-diprenylorobol has the potential antiproliferative effect against LoVo and HCT15 colon cancer cells through activation of p53 and generation of ROS.

Abstract
Purpose As the number of gastric cancer survivors is increasing and their quality of life after surgery is being emphasized, single-port surgery is emerging as an alternative to conventional gastrectomy. A novel multi-degree-of-freedom (DOF) articulating device, the ArtiSential® device (LivsMed, Seongnam, Korea), was designed to allow more intuitive and meticulous control for surgeons facing ergonomic difficulties with conventional tools. In this study, we evaluated the feasibility of this new device during single-port laparoscopic distal gastrectomy (SP-LDG) for early gastric cancer (EGC) patients. Materials and Methods Consecutive patients diagnosed with EGC who underwent SP-LDG with ArtiSential® (LivsMed) graspers between April 2018 and August 2020 were enrolled in the study. The clinical outcomes were compared with those of a control group, in which prebent graspers (Olympus Medical Systems Corp) were used for the same procedures. Results Seventeen patients were enrolled in the ArtiSential® group. There was no significant difference in operative time (205.4±6.0 vs. 218.1±9.9 minutes, P= 0.270) or the quality of surgery, in terms of the number of retrieved lymph nodes (49.5±3.5 vs. 45.9±4.0, P=0.473), length of hospital stay (15.4±2.0 vs. 12.4±1.3 days, P=0.588), and postoperative complications (40.0% vs. 41.2%, P=0.595), between the ArtiSential® group and the control group. Conclusions The new multi-DOF articulating grasper is feasible and can be used as an alternative for prebent graspers during SP-LDG.

Abstract
A recently discovered human glycoprotein, chitinase 3-like 1 (Chi3L1), may play a role in inflammation, tissue remodeling, and visceral fat accumulation. We hypothesize that Chi3L1 gene expression is important in the development of hepatic insulin resistance characterized by the generation of pAKT, pGSK, and pERK in wild type and Chi3L1 knockout (KO) murine liver following insulin stimulation. The Chi3L1 gene and protein expression was evaluated by Real Time PCR and ELISA; lipid accumulation in hepatocytes was also assessed. To alter Chi3L1 function, three different anti-Chi3L1 monoclonal antibodies (mAbs) were administered in vivo and effects on the insulin signaling cascade and hepatic lipid deposition were determined. Transmission of the hepatic insulin signal was substantially improved following KO of the CHi3L1 gene and there was reduced lipid deposition produced by a HFD. The HFD-fed mice exhibited increased Chi3L1 expression in the liver and there was impaired insulin signal transduction. All three anti-Chi3L1 mAbs partially restored hepatic insulin sensitivity which was associated with reduced lipid accumulation in hepatocytes as well. A KO of the Chi3L1 gene reduced lipid accumulation and improved insulin signaling. Therefore, Chi3L1 gene upregulation may be an important factor in the generation of NAFLD/NASH phenotype.

Abstract
BACKGROUND Few studies have presented evidence pertaining to the adequate minimum number of adjuvant chemotherapy (AC) cycles required to achieve an oncologic benefit for gastric cancer. METHODS From January 2012 to December 2013, data from patients who underwent curative radical gastrectomy and consequently received AC for pathologic stage 2 or 3 gastric cancer at 27 institutions in South Korea were analyzed. RESULTS The study enrolled 925 patients, 661 patients (71.5%) who completed 8 cycles of AC and 264 patients (28.5%) who did not. Compared with the mean disease-free survival (DFS) of the patients who completed 8 AC cycles (69.3 months), the mean DFS of patients who completed 6 AC cycles (72.4 months; p = 0.531) and those who completed 7 AC cycles (63.7 months; p = 0.184) did not differ significantly. However, the mean DFS of the patients who completed 5 AC cycles (48.2 months; p = 0.016) and those who completed 1-4 AC cycles (62.9 months; p = 0.036) was significantly lower than the DFS of those who completed 8 AC cycles. In the multivariate Cox proportional hazards analysis, the mean DFS was significantly affected by advanced stage, large tumor size, positive vascular invasion, and number of completed AC cycles (1-5 cycles: hazard ratio 1.45; 95% confidence interval 1.01-2.08; p = 0.041). CONCLUSION The current multicenter observational cohort study showed that the mean DFS for 6 or 7 AC cycles was similar to that for 8 AC cycles as an adjuvant treatment for gastric cancer.

Abstract
Background: No consensus exists regarding the superiority of either of the two types of gastrointestinal anastomosis, which are isoperistaltic and antiperistaltic. This study aimed to compare the clinical outcomes between isoperistaltic and antiperistaltic anastomoses after total laparoscopic distal gastrectomy (TLDG) in patients with gastric cancer. Methods: We retrospectively reviewed the medical records of patients with gastric cancer who underwent TLDG with Billroth II anastomosis between January 2014 and December 2018. The patients were divided into two groups according to the peristaltic direction of gastrointestinal anastomosis after TLDG. One group underwent isoperistaltic anastomosis (Iso group), and the other underwent antiperistaltic anastomosis (Anti group). Clinical outcomes were compared between the groups. Results: Of the 148 patients who underwent TLDG with Billroth II anastomosis, 124 were included in the Iso group and 24 were included in the Anti group. The Anti and Iso groups showed no significant difference with regard to the incidence of internal hernia (0.0 vs. 6.5%, respectively; p = 0.355). The incidence of bile reflux was more frequent in the Iso group than in the Anti group (p = 0.010), but food stasis was more common in the Anti group than in the Iso group (p = 0.006). Conclusion: In gastric cancer patients who underwent TLDG in which postoperative adhesion was minimized, antiperistaltic anastomosis may have created a physiologic barrier in gastrointestinal continuity. However, a large-scale study is necessary to validate the relationship between the digestive stream and the peristaltic direction.

Abstract
Tomentosin, a sesquiterpene lactone, is known to possess various biological activities. However, its anticarcinogenic activity against human hepatocellular carcinoma (HCC) cells has not been investigated in detail. Thus, this study aimed to elucidate the cytotoxic mechanism of tomentosin in human HCC cell lines HepG2 and Huh7. WST-1, cell counting, and colony formation assay results showed that treatment with tomentosin decreased the viability and suppressed the proliferation rate of HepG2 and Huh7 cells in a dose- and time-dependent manner. Cell cycle analysis revealed increased population of cells at the SubG1 and G2/M stage, and decreased population of cells at the G0/1 stage in HepG2 and Huh7 cells treated with tomentosin. Annexin V/propidium iodide double staining and TUNEL assay results showed increased apoptotic cell population and DNA fragmentation in HepG2 and Huh7 cells treated with tomentosin. Western blotting analysis results showed that tomentosin treatment significantly increased the expression level of Bax, Bim (short form), cleaved PARP1, FOXO3, p53, pSer15p53, pSer20p53, pSer46p53, p21, and p27, but decreased the expression of Bcl2, caspase3, caspase7, caspase9, cyclin-dependent kinase 2 (CDK2), CDK4, CDK6, cyclinB1, cyclinD1, cyclinD2, cyclinD3, and cyclinE in a dose-dependent manner. Taken together, this study revealed that tomentosin, which acted through cell cycle arrest and apoptosis, may be a useful therapeutic option against HCC.

Abstract
Purpose To compare long-term disease-free survival (DFS) between patients receiving tegafur/gimeracil/oteracil (S-1) or capecitabine plus oxaliplatin (CAPOX) adjuvant chemotherapy (AC) for gastric cancer (GC). Materials and Methods This retrospective multicenter observational study enrolled 983 patients who underwent curative gastrectomy with consecutive AC with S-1 or CAPOX for stage II or III GC at 27 hospitals in Korea between February 2012 and December 2013. We conducted propensity score matching to reduce selection bias. Long-term oncologic outcomes, including DFS rate over 5 years (over-5yr DFS), were analyzed postoperatively. Results The median and longest follow-up period were 59.0 and 87.6 months, respectively. DFS rate did not differ between patients who received S-1 and CAPOX for pathologic stage II (P=0.677) and stage III (P=0.899) GC. Moreover, hazard ratio (HR) for recurrence did not differ significantly between S-1 and CAPOX (reference) in stage II (HR, 1.846; 95% confidence interval [CI], 0.693–4.919; P=0.220) and stage III (HR, 0.942; 95% CI, 0.664–1.337; P=0.738) GC. After adjustment for significance in multivariate analysis, pT (4 vs. 1) (HR, 11.667; 95% CI, 1.595–85.351; P=0.016), pN stage (0 vs. 3) (HR, 2.788; 95% CI, 1.502–5.174; P=0.001), and completion of planned chemotherapy (HR, 2.213; 95% CI, 1.618–3.028; P<0.001) were determined as independent prognostic factors for DFS. Conclusions S-1 and CAPOX AC regimens did not show significant difference in over-5yr DFS after curative gastrectomy in patients with stage II or III GC. The pT, pN stage, and completion of planned chemotherapy were prognostic factors for GC recurrence.

Abstract
Background: Only few surgeons have tried to perform laparoscopic combined resection for T4b gastric cancer. The purpose of this study was to investigate the feasibility of laparoscopic combined resection through a comparison of the clinical outcomes between cT4a and cT4b cases. Methods: We reviewed the medical charts of patients who underwent laparoscopic gastrectomy for clinically T4 gastric cancer from May 2014 and July 2018. During this period, 62 patients with serosa-positive gastric cancer underwent laparoscopic curative surgery. The patients were divided into the following groups: patients who underwent gastrectomy and combined resection for the invaded organs (combined resection group) and those who did not undergo combined organ surgery (gastrectomy only group). Clinical outcomes were compared between the gastrectomy only and combined resection groups. Results: Of 62 patients included in this study, 43 and 19 patients were included in the gastrectomy only and combined resection groups, respectively. The operation time was significantly longer in the combined resection group (364.6 ± 102.5 vs. 247.7 ± 66.1 min; p < 0.001). The incidence of grade ≥ III complications was comparable between the groups (26.3% vs. 11.6%; p = 0.147). The time from the first operation to the initiation of adjuvant chemotherapy showed no statistically significant difference between the groups (48.1 ± 45.4 days vs. 31.6 ± 9.2; p = 0.134). Conclusions: Focusing on the high quality of image and new devices of laparoscopic surgery, it is necessary to re-evaluate the oncologic outcomes of combined resection for T4b gastric cancer.

Abstract
Few surgeons have adopted pancreaticoduodenectomy (PD) for the treatment of advanced gastric cancer (AGC) invading the pancreas or duodenum because it remains controversial whether its prognostic benefits outweigh the high morbidity rates in such advanced cases. However, recent technical advances have revived diverse surgical procedures in minimally invasive approaches. Inspired by this trend, laparoscopic PD procedures have been performed for AGC in our institute since 2014. We recently performed a laparoscopic Whipple's operation in a case of cT4b gastric cancer with invasion of the pancreatic head and duodenum.

Abstract
Studies on morbid obesity have shown remarkable improvement of diabetes in patients who have undergone bariatric operations. It was subsequently shown that these operations induce diabetes remission independent of the resultant weight loss; as a result, surgeons began to investigate whether operations for gastric cancer (GC) could have the same beneficial effect on diabetes as bariatric operations. It was then shown in multiple reports that followed that certain operations for GC were able to improve or even cure type 2 diabetes mellitus (T2DM) in GC patients. This finding gave rise to the concept of “oncometabolic surgery”, in which a patient diagnosed with both GC and T2DM undergo a single operation with the purpose of treating both diseases. With the increasing incidence of T2DM, oncometabolic surgery has the potential to improve the quality of life and even extend survival of many GC patients. However, because the GC patient population and the bariatric patient population are wildly different and because different GC operations have different properties, the effect of oncometabolic surgery must be carefully assessed and engineered in order to maximize benefit and avoid harm. This manuscript aims to summarize the findings made so far in the field of oncometabolic surgery and to provide an outlook regarding the possibility of oncometabolic surgery being incorporated into standard clinical practice.

Abstract
Background: Acellular dermal matrix is a biologic material derived from the skin of human cadaveric donors. It has been used successfully in the past to reduce complications in breast surgery and hernia repair. This investigation was aimed at assessing the feasibility of using acellular dermal matrix to support the anastomosis after gastrectomy with the aim of reducing anastomotic site leakage complications. Methods: Patients were randomly assigned to standard anastomotic reconstruction (control arm) or anastomotic reconstruction with acellular dermal matrix reinforcement (intervention arm). Surgical outcomes related to anastomotic complications were collected. Because actual anastomotic leaks found on imaging studies are infrequent and thus require a very high number of patient recruitment to detect statistically significant difference between the two groups, in this pilot investigation other clinical and laboratory measures that have been shown to correlate to or predict anastomotic leaks were also collected. Each surgical outcome was compared. Results: A total of 94 patients (intervention arm: 50, control arm: 44), were included in the analysis. Two patients in the control arm (4.55%) and one patient in the intervention arm (2.00%) experienced anastomotic leakage (p = 0.598), a difference without statistical significance. However, average postoperative C-reactive protein (CRP) levels and NUn scores, both of which have been shown to reflect likelihood of progressing to anastomotic leakage, were significantly lower for the intervention arm. The control arm showed an average CRP level of 128.77 mg/dL (SD: 97.08) while the intervention arm showed 77.38 mg/dL (SD: 49.08, p = 0.049). Conclusions: Leakage rate reduction with acellular dermal matrix reinforcement of anastomotic site was not detected in this investigation. However, postoperative inflammation levels and numerical predictors of anastomotic leakage development were significantly lower with acellular dermal matrix reinforcement of surgical anastomosis. This finding is worthy of further investigation, as reduction of inflammation with anastomotic site reinforcement is a novel finding, and more in-depth research may lead to discoveries on the physiologic role of the surgical anastomosis in post-gastrectomy patients. In addition, lower CRP and NUn scores for the intervention arm suggest potential for larger studies to detect reduction in clinical leak rates after acellular dermal matrix reinforcement.
