RESUMO
BACKGROUND: Although lumen-apposing metal stents (LAMSs) have been increasingly used for walled-off necrosis (WON), their advantages over plastic stents in infected WON are unclear. We investigated the safety and efficacy of a novel electrocautery-enhanced LAMS for managing infected WON. METHODS: Patients who required endoscopic ultrasound-guided WON drainage were randomly assigned to LAMS or plastic stent groups. The primary outcome was total number of direct endoscopic necrosectomy (DEN) procedures required to achieve clinical success. Secondary outcomes included rates of technical success, clinical success, and adverse events. RESULTS: 46 patients were included in the LAMS (n = 23) and plastic stent (n = 23) groups. The median total number of DEN procedures did not differ significantly between the plastic stent group (4 procedures, interquartile range [IQR] 2.5-5.0) and LAMS group (9 procedures, IQR 8.0-9.0) (P = 0.07). The LAMS group demonstrated a significantly higher clinical success rate than the plastic stent group based on intention-to-treat analysis (100% vs. 73.9%, P =0.03) at 8 weeks but not at 4 weeks. Significant bleeding occurred in one patient in the plastic stent group and no patients in the LAMS group. CONCLUSIONS: We found no significant difference in the total number of DEN procedures between LAMSs and plastic stents for managing infected WON. The only statistically significant finding was a higher clinical success rate at 8 weeks for patients treated with LAMS. The use of LAMS did not result in any adverse events, such as bleeding or buried LAMS syndrome, within the study duration.
RESUMO
BACKGROUND: There have been no previous studies that directly compared outcomes between cap-fitted forward-viewing and side viewing endoscopes (SE). This study aimed to compare the technical success rate and occurrence of adverse events between the side viewing and cap-fitted forward-viewing endoscope (CE) groups among patients with Billroth II anatomy who underwent ERCP. METHODS: The medical records of patients with a previous history of subtotal gastrectomy using Billroth II reconstruction who underwent ERCP at Yeungnam University Hospital between January 2004 and December 2020 were reviewed retrospectively. The patients were divided into CE and SE group. Propensity score matching analysis was performed to minimize selection bias. RESULTS: Propensity score matching resulted in 55 matched pairs for further analysis. Patients' characteristics were comparable in the matched cohorts. Final success rate of selective bile duct cannulation was not significantly different between the SE and CE groups (98.2% vs. 94.5%, p = 0.308). The complete CBD stone removal rate in CBD stone and successful biliary drainage rate in malignant biliary obstruction were not significantly different between the two groups. The rate of total ERCP-related adverse events was higher in the CE group than in the SE group, but the difference was not statistically significant (10.9% vs. 7.3%, p = 0.507). Among adverse events, the rate of post-ERCP pancreatitis showed higher tendency in the CE group than in the SE group (10.9% vs. 5.5%, p = 0.297). CONCLUSION: In conclusion, CE seems to be equally effective as SE for ERCP in patients with Billroth II anatomy. However, attention should be paid to development of post ERCP complications, especially pancreatitis, when performed by CE.

Lower back pain is a major problem caused by intervertebral disc degeneration. A common surgical procedure is lumbar partial discectomy (excision of the herniated disc causing nerve root compression), which results in further disc degeneration, severe lower back pain, and disability after discectomy. Thus, the development of disc regenerative therapies for patients who require lumbar partial discectomy is crucial. Here, we investigated the effectiveness of an engineered cartilage gel utilizing human fetal cartilage-derived progenitor cells (hFCPCs) on intervertebral disc repair in a rat tail nucleotomy model. Eight-week-old female Sprague-Dawley rats were randomized into three groups to undergo intradiscal injection of (1) cartilage gel, (2) hFCPCs, or (3) decellularized extracellular matrix (ECM) (n = 10/each group). The treatment materials were injected immediately after nucleotomy of the coccygeal discs. The coccygeal discs were removed six weeks after implantation for radiologic and histological analysis. Implantation of the cartilage gel promoted degenerative disc repair compared to hFCPCs or hFCPC-derived ECM by increasing the cellularity and matrix integrity, promoting reconstruction of nucleus pulposus, restoring disc hydration, and downregulating inflammatory cytokines and pain. Our results demonstrate that cartilage gel has higher therapeutic potential than its cellular or ECM component alone, and support further translation to large animal models and human subjects.

Functionally enhanced mesenchymal stromal cells participate in the repair of intervertebral disc. This study aimed to assess the safety and tolerability of intradiscal administration of matrilin-3-primed adipose-derived stromal cell (ASC) spheroids with hyaluronic acid (HA) in patients with chronic discogenic low back pain (LBP). In this single-arm, open-label phase I clinical trial, eight patients with chronic discogenic LBP were observed over 6 months. Each patient underwent a one-time intradiscal injection of 1 mL of 6.0 × 106 cells/disc combined with HA under real-time fluoroscopic guidance. Safety and feasibility were gauged using Visual Analogue Scale (VAS) pain and Oswestry Disability Index (ODI) scores and magnetic resonance imaging. All participants remained in the trial, with no reported adverse events linked to the procedure or stem cells. A successful outcome-marked by a minimum 2-point improvement in the VAS pain score and a 10-point improvement in ODI score from the start were observed in six participants. Although the modified Pfirrmann grade remained consistent across all participants, radiological improvements were evident in four patients. Specifically, two patients exhibited reduced high-intensity zones while another two demonstrated decreased disc protrusion. In conclusion, the intradiscal application of matrilin-3-primed ASC spheroids with HA is a safe and feasible treatment option for chronic discogenic LBP.

The therapeutic potential of Mesenchymal stem cells (MSCs) for the treatment of Intervertebral disc (IVD) degeneration can be enhanced by amplifying specific cytokines and proteins. This study aimed to investigate the therapeutic potential of tetracycline-off system-engineered tonsil-derived mesenchymal stem cells (ToMSC-Tetoff-TGFß1-IGF1-BMP7) for treating intervertebral disc (IVD) degeneration. ToMSCs were isolated from a tonsillectomy patient and genetically modified with four distinct plasmids via CRISPR/Cas9-mediated knock-in gene editing. Transgene expression was confirmed through immunofluorescence, western blots, and an enzyme-linked immunosorbent assay for transforming growth factor beta 1 (TGFß1) protein secretion, and the effect of MSC-TetOff-TGFß1-IGF1-BMP7 on disc injury was assessed in a rat model. The ToMSC-Tetoff-TGFß1-IGF1-BMP7 treatment exhibited superior therapeutic effects compared to ToMSC-TGFß1, and ToMSC-SDF1α implantation groups, stimulating the regeneration of nucleus pulposus (NP) cells crucial for IVD. The treatment showed potential to restore the structural integrity of the extracellular matrix (ECM) by upregulating key molecules such as aggrecan and type II collagen. It also exhibited anti-inflammatory properties and reduced pain-inducing neuropeptides. ToMSC-Tetoff-TGFß1-IGF1-BMP7 holds promise as a novel treatment for IVD degeneration. It appears to promote NP cell regeneration, restore ECM structure, suppress inflammation, and reduce pain. However, more research and clinical trials are required to confirm its therapeutic potential.

Although the COVID-19 pandemic has triggered growing public interest in veganism, veganism's conceptualization remains ambiguous. Moreover, vegans' and nonvegans' different perspectives have rarely been addressed. Hence, this study involved the opinions of both vegans and nonvegans in the COVID-19 context to understand their attitudes, motivations, and opinions related to veganism. We analyzed online discourses in vegan and antivegan online communities using Word2Vec analysis and qualitative analysis. We identified lists of terms associated with three key veganism dimensions (i.e., lifestyle, animal rights, and food). Moreover, we compared actual online discussions among vegans to those among nonvegans regarding specific veganism attributes. This study preliminarily identifies specific attributes associated with veganism in online discourse among vegans. The issues addressed in this study can be tested in future research. Our findings can also be useful for people in various stages of veganism-such as active vegans, people who are interested in veganism, or even nonvegans who are uninterested in veganism-to comprehend the different perceptions prevailing in each group.
RESUMO
OBJECTIVE: To present an optimized examination model by analyzing the risk of disease and image quality according to the combination of the ion chamber of automatic exposure control (AEC) with digital radiography (DR). METHODS: The X-ray quality was analyzed by first calculating the percentage average error (PAE) of DR. After that, when using AEC, the combination of the ion chambers was the same as the left and centre and right, right and centre, left and centre, centre, right, and left, for a total of six. Accordingly, the entrance surface dose (ESD), risk of disease, and image quality were evaluated. ESD was obtained by attaching a semiconductor dosimeter to the L4 level of the lumbar spine, and then irradiating X-rays to dosimeter centre through average and standard deviation of radiation dose. The calculated ESD was input into the PCXMC 2.0 programme to evaluate disease risk caused by radiation. Meanwhile, image quality according to chamber combination was quantified as the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) through Image J. RESULTS: X-ray quality of DR used in the experiment was within the normal range of±10. ESD of six ion chamber combinations was 1.363mGy, 0.964mGy, 0.946mGy, 0.866mGy, 0.748mGy, 0.726mGy for lumbar anteroposterior (AP), and the lumbar lateral values were 1.126mGy, 0.209mGy, 0.830mGy, 0.662mGy, 0.111mGy, and 0.250mGy, respectively. Meanwhile, disease risk analyzed through PCXMC 2.0 was bone marrow, colon, liver, lung, stomach, urinary and other tissue cancer, and disease risk showed a tendency to increase in proportion to ESD. SNR and CNR recorded the lowest values when three chambers were combined and did not show proportionality with dose, while showed the highest values when two chambers were combined. CONCLUSION: In this study, combination of three ion chambers showed the highest disease risk and lowest image quality. Using one ion chamber showed the lowest disease risk, but lower image quality than two ion chambers. Therefore, if considering all above factors, combination of two ion chambers can optimally maintain the disease risk and image quality. Thus, it is considered an optimal X-ray examination parameter.

Background and Objectives: Acute peripancreatic fluid collection (APFC) is an acute local complication of acute pancreatitis (AP) according to the revised Atlanta classification. Sometimes APFC resolves completely, sometimes it changes into a pseudocyst or walled-off necrosis (WON), so called late complications. The aim of this study is to investigate the natural course of APFC detected on early computed tomography (CT) in moderately severe (MSAP) or severe AP (SAP). Materials and Methods: From October 2014 to September 2015, patients with MSAP or SAP were enrolled if there was APFC within 48 h of onset on imaging studies at six medical centers. The status of fluid collection was followed 4-8 weeks after onset. Initial laboratory findings, CT findings and clinical scoring systems were analyzed. Results: A total of 68 patients were enrolled and APFC was completely resolved in 32 (66.7%) patients in the MSAP group and 9 (34.6%) in the SAP group. Patients with a high bedside index for severity in acute pancreatitis (BISAP) score (≥3 points) were common in the SAP group. C-reactive protein (CRP) after 48 h from admission and BUN level were also high in the SAP group. In multivariate analysis, BISAP score (≥3 points), elevation of CRP after 48 h (≥150 mg/L) and nasojejunal feeding after 48 h were risk factors for the development of late complications. Conclusions: Spontaneous resolution of APFC was more common in MSAP group and APFC can be changed to pseudocyst or WON in patients with elevated BISAP score, CRP level after 48 h, and non-improved abdominal pain.

The importance of the risk to tourism and hospitality operations from pandemic-related crises has increased. Therefore, the current study offers a literature review targeting tourism and hospitality stakeholders' perceptions of past diseases and has three objectives: (1) Explore major topics from previous research on infectious diseases using topic modeling; (2) compare non-COVID-19 and COVID-19 crises; (3) investigate research topics in the tourism and hospitality industries. To meet our research objectives, we reviewed published pandemic-related articles in the tourism and hospitality literature since the year 2000. Based on the results, we first identified nine key topics related to infectious diseases (i.e., policy, human resources, branding, resilience, technology, global or community change, risk perception, disease impact, and lifestyle). Second, we suggest the application of different topic weights in non-COVID-19 and COVID-19 research. Third, we found that it is appropriate to apply different topic weights in tourism and hospitality research.
RESUMO
BACKGROUND: Previous studies on the relationship between gastrointestinal (GI) cancer and cholecystectomy remain inconclusive. We aimed to evaluate this relationship, albeit particularly between cholecystectomy and gastric cancer or colorectal cancer (CRC), and the risk factors of cancer among individuals who have undergone cholecystectomy in Korea. METHODS: In total, 4,222 patients who underwent laparoscopic or open cholecystectomy at our institution between January 2006 and December 2013 were included. Patients who underwent cholecystectomy for gallbladder cancer or were undergoing surgery for GI, hepatic, or pancreatobiliary cancers were excluded, as were those who developed stomach cancer or CRC within a year of their cholecystectomy. The included patients were followed until July 20, 2020. The standardized incidence ratio (SIR) was used to calculate the relative risk of GI cancer in cholecystectomy patients. RESULTS: The median patient age (n = 3,588) at the time of cholecystectomy was 54.0 (range, 19-95) years, and the male-to-female ratio was 1:1.04. The median follow-up period after cholecystectomy was 15.0 (range, 0-146) months. We found a 108% greater risk of CRC (SIR, 2.08; 95% confidence interval [CI], 1.28-3.17) and 154% increased risk of CRC in females (SIR, 2.54; 95% CI, 1.16-4.84). Based on multivariate analysis, an age of > 60 years was a significant risk factor for GI cancer in cholecystectomy patients. CONCLUSION: Cholecystectomy may increase risk of CRC, especially in females. Age was considered a risk factor of GI cancers in patients with history of cholecystectomy.

BACKGROUND AND AIM: Previous studies evaluating the safety of endoscopic retrograde cholangiopancreatography (ERCP) in patients with end-stage renal disease (ESRD) undergoing hemodialysis reported an increased risk of post-procedural bleeding. We investigated the safety and efficacy of ERCP for the treatment of choledocholithiasis in patients with ESRD undergoing long-term dialysis. METHODS: A total of 3466 patients who underwent ERCP due to choledocholithiasis between January 2000 and Feb 2018 were reviewed and analyzed retrospectively. Patients were divided into dialysis and non-dialysis group, and propensity score matching was used to minimize selection bias. RESULTS: Patients of dialysis group (n = 39) and non-dialysis group (n = 78) were compared after propensity score matching. Among 39 patients of dialysis group, hemodialysis was used in 28 (71.8%) patients for renal replacement therapy, while 11 (28.2%) patients received peritoneal dialysis. The median duration of dialysis was 8 years (range 1-24 years). Overall success rate of ERCP was not different between two groups. The overall prevalence of post-procedural complications in dialysis group and non-dialysis group was 28.2 and 15.4%, respectively (p = 0.100). Post-procedural bleeding occurred more frequently in dialysis group than non-dialysis group (23.1 vs 5.1%, p = 0.004). All procedure-related bleeding episodes were successfully controlled using endoscopic management. Prevalence of post-ERCP pancreatitis, infection, and perforation were not significantly different between two groups (p > 0.05). CONCLUSIONS: Overall success rate of complete ductal clearance was not different between dialysis and non-dialysis groups. The risk of post-procedural bleeding seems to be increased in patients with ESRD undergoing long-term dialysis.

INTRODUCTION: Acute biliary pancreatitis (ABP) is a severe complication of gallstone disease with considerable mortality, and its recurrence rate is reported as 50-90% for ABP patients who do not undergo cholecystectomy. However, the incidence of and risk factors for recurrent pancreatobiliary complications after the initial improvement of ABP are not well established in the literature. The aims of this study were to determine the risk factors for recurrent pancreatobiliary complications and to compare the outcomes between early (within 2 weeks after onset of pancreatitis) and delayed cholecystectomy in patients with ABP. METHODS: Patients diagnosed with ABP at Yeungnam University Hospital from January 2004 to July 2016 were retrospectively reviewed. The following risk factors for recurrent pancreatobiliary complications (acute pancreatitis, acute cholecystitis, and acute cholangitis) were analyzed: demographic characteristics, laboratory data, size and number of gallstones, severity of pancreatitis, endoscopic sphincterotomy, and timing of cholecystectomy. Patients were categorized into two groups: patients with recurrent pancreatobiliary complications (Group A) and patients without pancreatobiliary complications (Group B). RESULTS: Of the total 290 patients with ABP (age 66.8 ± 16.0 years, male 47.9%), 56 (19.3%) patients developed recurrent pancreatobiliary complications, of which 35 cases were acute pancreatitis, 11 cases were acute cholecystitis, and 10 cases were acute cholangitis. Endoscopic sphincterotomy and cholecystectomy were performed in 134 (46.2%) patients and 95 (32.8%) patients, respectively. Age, sex, BMI, diabetes, number of stone, severity of pancreatitis, and laboratory data were not significantly correlated with recurrent pancreatobiliary complications. The risk of recurrent pancreatobiliary complications was significantly increased in the delayed cholecystectomy group compared with the early cholecystectomy group (45.5 vs. 5.0%, p < 0.001). Based on the multivariate logistic regression analyses, two factors, size of gallstone less than or equal to 5 mm and delayed cholecystectomy, were found as risk factors associated with recurrent pancreatobiliary complications. CONCLUSION: The incidence of recurrent pancreatobiliary complications was 19.3% and was significantly increased in patients with size of gallstone less than or equal to 5 mm and in those who underwent delayed cholecystectomy.

BACKGROUND AND AIMS: Adherence to medication during the treatment of inflammatory bowel disease (IBD) is important in terms of maintaining remission. According to studies on adherence to medication in other chronic diseases, non-adherence is associated with negative attitudes to treatment. The aims of this study were to assess adherence rates and IBD patients' beliefs and attitudes regarding medication using a questionnaire based approach. METHODS: Two hundred and eighty seven patients from three tertiary hospitals were enrolled and completed a questionnaire that addressed adherence (Medication Adherence Report Scale, MARS), beliefs, and attitudes to medication (Beliefs about Medications Questionnaire, BMQ). RESULTS: Using a cutoff score of 16/20 for MARS, 64 (22.3%) patients did not adhere to medication. According to attitude analysis conducted using the BMQ, 41.8% of the 287 study subjects felt high necessity but low concern for the medication ("accepting") and 34.8% felt high necessity and concern ("ambivalent"). Multivariate analysis showed significantly lower adherence to medication among younger patients, patients with experience of adverse effects to medication, patients with demanding jobs, and for those with an "indifferent" or "skeptical" attitude regarding the benefits of medication. On the other hand, IBD patients with "accepting" attitude adhered to medication. CONCLUSION: Twenty-two percent of IBD patients were non-adherent to medical treatment, and belief of the need for medication was found to significantly enhance adherence. Interventions, such as education about the efficacy and safety of medications, should be considered to facilitate adherence to medical treatment among IBD patients.

INTRODUCTION: Endoscopic retrograde cholangiopancreatography (ERCP) is generally recommended for removal of CBD stones. There were no studies focusing on the role of symptoms related to CBD stone in performing endoscopic stone removal. The aim of our study was to compare outcomes and complications of ERCP between asymptomatic and symptomatic CBD stones. METHODS: The medical records of 568 patients with naïve papilla who underwent ERCP for treatment of CBD stone from Jan 2009 to Aug 2014 were reviewed and analyzed retrospectively. Patients were divided as asymptomatic group (n = 32) and symptomatic group (n = 536). RESULTS: Age and gender were not significantly different between the two groups (p > 0.005). Mean sizes of CBD and CBD stones were not significantly different between asymptomatic and symptomatic group (p > 0.05). No differences in performance of needle knife fistulotomy, endoscopic sphincterotomy, and endoscopic papillary balloon dilatation were observed between the two groups (p > 0.05). Unintentional injection into the pancreatic duct was not significantly different between the two groups (p > 0.05). The overall complete stone removal rate was 96.9 % in the asymptomatic group and 94.4 % in the symptomatic group (p = 0.295). Requirement of mechanical lithotripsy was not significantly different between asymptomatic and symptomatic group (18.8 vs 8.4 %, p = 0.057). Significantly higher incidence of post-ERCP pancreatitis was observed in the asymptomatic group than in the symptomatic group (12.5 vs 3.9 %, p = 0.045). CONCLUSION: The overall success rates of CBD stone removal were comparable between asymptomatic and symptomatic patients. However, risk of post-ERCP pancreatitis appears to be increased in patients with asymptomatic CBD stones.

BACKGROUND: Re-bleeding after initial hemostasis in peptic ulcer bleeding can be life threatening. Identification of factors associated with re-bleeding is important. The aims of this study were to determine incidence of rebleeding in patients with high risk peptic ulcer bleeding and to evaluate factors associated with rebleeding. METHODS: Among patients diagnosed as upper gastrointestinal hemorrhage at seven hospitals in Daegu-Gyeongbuk, and one hospital in Gyeongnam, South Korea, from Feb 2011 to Dec 2013, 699 patients diagnosed as high risk peptic ulcer bleeding with Forrest classification above llb were included. The data were obtained in a prospective manner. RESULTS: Among 699 patients, re-bleeding occurred in 64 (9.2 %) patients. Second look endoscopy was significantly more performed in the non-rebleeding group than the rebleeding group (81.8 vs 62.5 %, p < 0.001). In multivariate analysis, use of non-steroidal anti-inflammatory agents, larger transfusion volume (≥5 units), and non-performance of second look endoscopy were found as risk factors for rebleeding in high risk peptic ulcer bleeding. CONCLUSION: In our study, rebleeding was observed in 9.2 % of patients with high risk peptic ulcer bleeding. Performance of second look endoscopy seems to lower the risk of rebleeding in high risk peptic ulcer bleeding patients and caution should be paid to patients receiving high volume transfusion and on medication with NSAIDs.

BACKGROUND: Although anterior cervical decompression and fusion with a stand-alone cage (ACDF-SAC) is accepted as a suitable procedure, the outcomes of the multi-level procedure remain controversial. The aim of this study is to compare the clinical and radiologic outcomes achieved with single versus two-level ACDF-SAC along with identification of the factors that contribute to loss in mean disc height (MDH) and change in cervical lordotic angle (CLA). METHODS: A total of 109 consecutive patients who underwent ACDF-SAC for degenerative spondylosis were reviewed. Patients were divided into two groups according to surgical level (group A, single; group B, two) and were followed for at least 1 year. Clinical outcomes were evaluated using the visual analog scale (VAS) and Robinson's criteria. The fusion and subsidence rates, MDH, CLA, anterior, and posterior vertebral body height of the fused segments (AVBH, PVBH) were measured retrospectively from plain radiographs. RESULTS: Clinical outcomes were similar in both groups, in terms of decreasing VAS score and a grade higher than "good" by Robinson's criteria. The fusion and subsidence rates for each group were found to be 92.2, 91.1, 14.1, and 20.0 %, respectively. The MDH (mm) increased by 1.44 ± 0.96 in group A, 1.57 ± 0.79 and 1.66 ± 0.69 for each surgical level in group B over the 12 postoperative months. The CLA (°) decreased by 1.70 ± 4.04 and 0.75 ± 6.12 over the 12 postoperative months from its presurgery value, the rate of kyphosis >5° was 26.6 and 22.2 % for each group. All compared values were not significantly different between the two groups. Correlation analysis revealed that the AVBH/PVBH ratio exhibited a positive correlation with CLA change in both groups (r = 0.368, 0.397; p = 0.018, 0.040). CONCLUSIONS: The overall outcomes achieved with two-level ACDF-SAC were similar to those achieved with single-level ones. In addition, the AVBH/PVBH ratio might be a predictable marker for a postoperative kyphosis.

The aims of this study were to review the clinicopathological characteristics of diminutive (≤ 5 mm) and small polyps (> 5 mm but < 10 mm) and to evaluate the risk factors of advanced adenoma for polyps of diameter < 10 mm in the colon. The medical records of 4,711 patients who underwent first colonoscopy at outpatient clinics or health promotion center were reviewed retrospectively. We analyzed the presence and risk factors of advanced adenoma, which was defined as a villous or tubulovillous polyp, high-grade dysplasia or intramucosal carcinoma histologically. Total 5,058 polyps were detected in the 4,711 patients, and 93.0% (4,704/5,058) polyps were < 10 mm in size. Among them, advanced adenoma was noted in 0.6% (28/4,704) with a villous component in 19, high-grade dysplasia in 3, and adenocarcinoma in 6. Advanced and non-advanced adenomas differed significantly in age group, gender, and polyp size. Multivariate analysis showed that an advanced age (> 65 years), a male gender, and a polyp size of > 5 mm were risk factors of advanced adenoma. The incidence of advanced adenoma in polyps of < 10 mm was 0.6%. Polyp size, male gender, and age of > 65 years are independent risk factors of advanced adenoma.
