Abstract
BACKGROUND Chest radiography is a common and widely available examination. Although cardiovascular structures-such as cardiac shadows and vessels-are visible on chest radiographs, the ability of these radiographs to estimate cardiac function and valvular disease is poorly understood. Using datasets from multiple institutions, we aimed to develop and validate a deep-learning model to simultaneously detect valvular disease and cardiac functions from chest radiographs. METHODS In this model development and validation study, we trained, validated, and externally tested a deep learning-based model to classify left ventricular ejection fraction, tricuspid regurgitant velocity, mitral regurgitation, aortic stenosis, aortic regurgitation, mitral stenosis, tricuspid regurgitation, pulmonary regurgitation, and inferior vena cava dilation from chest radiographs. The chest radiographs and associated echocardiograms were collected from four institutions between April 1, 2013, and Dec 31, 2021: we used data from three sites (Osaka Metropolitan University Hospital, Osaka, Japan; Habikino Medical Center, Habikino, Japan; and Morimoto Hospital, Osaka, Japan) for training, validation, and internal testing, and data from one site (Kashiwara Municipal Hospital, Kashiwara, Japan) for external testing. We evaluated the area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and accuracy. FINDINGS We included 22 551 radiographs associated with 22 551 echocardiograms obtained from 16 946 patients. The external test dataset featured 3311 radiographs from 2617 patients with a mean age of 72 years [SD 15], of whom 49·8% were male and 50·2% were female. The AUCs, accuracy, sensitivity, and specificity for this dataset were 0·92 (95% CI 0·90-0·95), 86% (85-87), 82% (75-87), and 86% (85-88) for classifying the left ventricular ejection fraction at a 40% cutoff, 0·85 (0·83-0·87), 75% (73-76), 83% (80-87), and 73% (71-75) for classifying the tricuspid regurgitant velocity at a 2·8 m/s cutoff, 0·89 (0·86-0·92), 85% (84-86), 82% (76-87), and 85% (84-86) for classifying mitral regurgitation at the none-mild versus moderate-severe cutoff, 0·83 (0·78-0·88), 73% (71-74), 79% (69-87), and 72% (71-74) for classifying aortic stenosis, 0·83 (0·79-0·87), 68% (67-70), 88% (81-92), and 67% (66-69) for classifying aortic regurgitation, 0·86 (0·67-1·00), 90% (89-91), 83% (36-100), and 90% (89-91) for classifying mitral stenosis, 0·92 (0·89-0·94), 83% (82-85), 87% (83-91), and 83% (82-84) for classifying tricuspid regurgitation, 0·86 (0·82-0·90), 69% (68-71), 91% (84-95), and 68% (67-70) for classifying pulmonary regurgitation, and 0·85 (0·81-0·89), 86% (85-88), 73% (65-81), and 87% (86-88) for classifying inferior vena cava dilation. INTERPRETATION The deep learning-based model can accurately classify cardiac functions and valvular heart diseases using information from digital chest radiographs. This model can classify values typically obtained from echocardiography in a fraction of the time, with low system requirements and the potential to be continuously available in areas where echocardiography specialists are scarce or absent. FUNDING None.

Abstract
BACKGROUND Early diagnosis of rotator cuff tears is essential for appropriate and timely treatment. Although radiography is the most used technique in clinical practice, it is difficult to accurately rule out rotator cuff tears as an initial imaging diagnostic modality. Deep learning-based artificial intelligence has recently been applied in medicine, especially diagnostic imaging. This study aimed to develop a deep learning algorithm as a screening tool for rotator cuff tears based on radiography. METHODS We used 2803 shoulder radiographs of the true anteroposterior view to develop the deep learning algorithm. Radiographs were labeled 0 and 1 as intact or low-grade partial-thickness rotator cuff tears and high-grade partial or full-thickness rotator cuff tears, respectively. The diagnosis of rotator cuff tears was determined based on arthroscopic findings. The diagnostic performance of the deep learning algorithm was assessed by calculating the area under the curve (AUC), sensitivity, negative predictive value (NPV), and negative likelihood ratio (LR-) of test datasets with a cutoff value of expected high sensitivity determination based on validation datasets. Furthermore, the diagnostic performance for each rotator cuff tear size was evaluated. RESULTS The AUC, sensitivity, NPV, and LR- with expected high sensitivity determination were 0.82, 84/92 (91.3%), 102/110 (92.7%), and 0.16, respectively. The sensitivity, NPV, and LR- for full-thickness rotator cuff tears were 69/73 (94.5%), 102/106 (96.2%), and 0.10, respectively, while the diagnostic performance for partial-thickness rotator cuff tears was low at 15/19 (78.9%), NPV of 102/106 (96.2%) and LR- of 0.39. CONCLUSIONS Our algorithm had a high diagnostic performance for full-thickness rotator cuff tears. The deep learning algorithm based on shoulder radiography helps screen rotator cuff tears by setting an appropriate cutoff value. LEVEL OF EVIDENCE Level III: Diagnostic Study.

Abstract
We aimed to develop the deep learning (DL) predictive model for postoperative early recurrence (within 2 years) of hepatocellular carcinoma (HCC) based on contrast-enhanced computed tomography (CECT) imaging. This study included 543 patients who underwent initial hepatectomy for HCC and were randomly classified into training, validation, and test datasets at a ratio of 8:1:1. Several clinical variables and arterial CECT images were used to create predictive models for early recurrence. Artificial intelligence models were implemented using convolutional neural networks and multilayer perceptron as a classifier. Furthermore, the Youden index was used to discriminate between high- and low-risk groups. The importance values of each explanatory variable for early recurrence were calculated using permutation importance. The DL predictive model for postoperative early recurrence was developed with the area under the curve values of 0.71 (test datasets) and 0.73 (validation datasets). Postoperative early recurrence incidences in the high- and low-risk groups were 73% and 30%, respectively (p = 0.0057). Permutation importance demonstrated that among the explanatory variables, the variable with the highest importance value was CECT imaging analysis. We developed a DL model to predict postoperative early HCC recurrence. DL-based analysis is effective for determining the treatment strategies in patients with HCC.

Abstract
Accurate estimation of mortality and time to death at admission for COVID-19 patients is important and several deep learning models have been created for this task. However, there are currently no prognostic models which use end-to-end deep learning to predict time to event for admitted COVID-19 patients using chest radiographs and clinical data. We retrospectively implemented a new artificial intelligence model combining DeepSurv (a multiple-perceptron implementation of the Cox proportional hazards model) and a convolutional neural network (CNN) using 1356 COVID-19 inpatients. For comparison, we also prepared DeepSurv only with clinical data, DeepSurv only with images (CNNSurv), and Cox proportional hazards models. Clinical data and chest radiographs at admission were used to estimate patient outcome (death or discharge) and duration to the outcome. The Harrel's concordance index (c-index) of the DeepSurv with CNN model was 0.82 (0.75-0.88) and this was significantly higher than the DeepSurv only with clinical data model (c-index = 0.77 (0.69-0.84), p = 0.011), CNNSurv (c-index = 0.70 (0.63-0.79), p = 0.001), and the Cox proportional hazards model (c-index = 0.71 (0.63-0.79), p = 0.001). These results suggest that the time-to-event prognosis model became more accurate when chest radiographs and clinical data were used together.

Abstract
BACKGROUND Autonomic dysfunction is a factor in irritable bowel syndrome (IBS). However, there are no reports of autonomic nervous system (ANS) activity during natural defecation in patients with IBS. We aimed to clarify the relationship between ANS activity and life events, such as defecation and abdominal symptoms, using real-time recording. METHODS Six patients with IBS and 14 healthy controls were enrolled in this prospective multicenter study. ANS activity was recorded for 24 h using a T-shirt wearable device, and life events were recorded simultaneously in real time using a smartphone application software. Low frequency/high frequency (LF/HF) and HF calculated by power spectrum analysis were defined as activity indicators of the sympathetic and parasympathetic nerves, respectively. RESULTS The means of LF/HF and HF in the period with positive symptoms were comparable between the groups; however, the sum of LF/HF, sum of ΔLF/HF, and the maximum variation in ΔLF/HF were significantly higher in the IBS group. In the IBS group, the sum of ΔLF/HF and LF/HF increased significantly from 2 min before defecation, and the sum of LF/HF remained significantly higher until 9 min after defecation. The sum of ΔLF/HF at 2 min before defecation was significantly positively correlated with the intensity of abdominal pain and diarrhea and constipation scores. In contrast, it was significantly negatively correlated with defecation satisfaction and health-related quality of life. CONCLUSIONS In patients with IBS, sympathetic nerve activity was activated 2 min before defecation, which was correlated with abdominal symptoms and lower QOL.

Abstract
Abstract
Introduction
The International Atherosclerosis Society (IAS) has proposed “severe familial hypercholesterolemia” (FH) as a phenotype with the highest cardiovascular risk. LDL-C <2.5 mmol/l is a recommended therapeutic goal for the primary prevention settings of severe FH. However, given that ESC guidelines recommends LDL-C <1.8 mmol/l in FH patients, this stricter goal may be better to prevent the first atherosclerotic cardiovascular disease (ASCVD) in severe FH patients.
Purpose
To determine whether achieving LDL-C<1.8 mg/dl is more beneficial to reduce the first ASCVD events.
Methods
A total of 148 severe FH subjects without any history of ASCVD were analyzed. Severe FH was defined as untreated LDL-C >10.3 mmol/l, LDL-C >8.0 mmol/l+ 1 high-risk feature, LDL-C >4.9 mmol/l + 2 high-risk features according to IAS proposed statement. The occurrence of ASCVD (all-cause death, CAD, ischemic stroke and lower extremity artery disease (LEAD)) were compared in those with on-treatment LDL-C < and ≥1.8 mmol/L.
Results
10.1% (=15/148) of study subjects achieved on-treatment LDL-C <1.8 mmol/l. They were more likely to receive PCSK9 inhibitor (15.0 vs. 66.7%, p<0.01), whereas there was no significant difference in FH-related physical characteristics (tendon xanthomas: 72.2 vs. 93.3%, p=0.12) and causative genotypes (LDLR: 68.4 vs. 66.7%, p=1.00, PCSK9: 8.3 vs. 6.7%, p=1.00, LDLR/PCSK9: 3.8 vs. 6.7%, p=0.48), untreated LDL-C (7.3±1.7 vs. 7.9±1.8 mmol/l, p=0.22) and lipoprotein(a) (23 [11–42] vs. 25 [15–70] mg/dl, p=0.41) levels between two groups. During the observational period (median=7.0 years), severe FH achieving on-treatment LDL-C <1.8 mmol/l was associated with a lower likelihood of experiencing ASCVD events (Figure 1). Of note, any cardiovascular events did not occur in severe FH who achieved on-treatment LDL-C <1.8 mmol/l. In those with on-treatment LDL ≥1.8 mmol/L, CAD (76.5%=26/34) was more dominant component of ASCVD, followed by ischemic stroke (17.6%=6/34) and LEAD (5.9%=2/34).
Conclusions
A significantly lower frequency of ASCVD was observed in severe FH who achieved LDL-C <1.8 mmol/L in the primary prevention settings. Given that only 10.1% of severe FH patients achieved LDL-C <1.8 mmol/l, more actions are required to motivate physicians for further intensified management of LDL-C in severe FH patients in the primary prevention settings.

Abstract
Objectives The objective of this study was to develop and validate a state-of-the-art, deep learning (DL)-based model for detecting breast cancers on mammography. Methods Mammograms in a hospital development dataset, a hospital test dataset, and a clinic test dataset were retrospectively collected from January 2006 through December 2017 in Osaka City University Hospital and Medcity21 Clinic. The hospital development dataset and a publicly available digital database for screening mammography (DDSM) dataset were used to train and to validate the RetinaNet, one type of DL-based model, with five-fold cross-validation. The model’s sensitivity and mean false positive indications per image (mFPI) and partial area under the curve (AUC) with 1.0 mFPI for both test datasets were externally assessed with the test datasets. Results The hospital development dataset, hospital test dataset, clinic test dataset, and DDSM development dataset included a total of 3179 images (1448 malignant images), 491 images (225 malignant images), 2821 images (37 malignant images), and 1457 malignant images, respectively. The proposed model detected all cancers with a 0.45–0.47 mFPI and had partial AUCs of 0.93 in both test datasets. Conclusions The DL-based model developed for this study was able to detect all breast cancers with a very low mFPI. Our DL-based model achieved the highest performance to date, which might lead to improved diagnosis for breast cancer.

Abstract
Background There is a need for a large-scale screening test that can be used to detect dementia in older individuals at an early stage. Olfactory identification deficits have been shown to occur in the early stages of dementia, indicating their usefulness in screening tests. This study investigated the utility of an olfactory identification test as a screening test for mild cognitive dysfunction in community-dwelling older people. Methods The subjects were city-dwelling individuals aged over 65 years but under 85 years who had not been diagnosed with dementia or mild cognitive impairment. The Japanese version of the Mild Cognitive Impairment Screen was used to evaluate cognitive function. Based on the results, the subjects were divided into two groups: healthy group and cognitively impaired group. Olfactory identification abilities based on the Japanese version of the University of Pennsylvania Smell Identification Test were compared between the groups. Results There were 182 participants in total: 77 in the healthy group and 105 in the cognitively impaired group. The mean olfactory identification test score of the cognitively impaired group was significantly lower than that of the healthy group. The cognitive impairment test score was significantly correlated with the olfactory identification test score. Conclusions Cross-sectional olfactory identification deficits at baseline in community-dwelling older adults reflected cognitive dysfunction. Assessing olfactory identification ability might be useful as a screening test for mild cognitive dysfunction in community-dwelling older people.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is becoming widely popular as a less invasive treatment option for superficial esophageal squamous cell carcinoma. However, data on long-term survival after esophageal ESD in patients with severe comorbidities are limited. This study aimed to evaluate long-term survival after ESD in such patients. METHODS Altogether, 584 consecutive patients underwent esophageal ESD at our institution from May 2004 to September 2016. Based on the American Society of Anesthesiologists Physical Status (ASA-PS) classification system, patients were grouped according to severe (ASA-PS ≥ 3) or non-severe comorbidities (ASA-PS 1/2). The overall survival (OS), disease-specific survival (DSS), and risk factors for mortality were compared between the groups using a propensity score matching analysis. RESULTS In a matched cohort of 69 pairs, the 5-year OS rate was poorer in ASA-PS 3 patients than in ASA-PS 1/2 patients (63.9% vs. 92.5%, P < 0.01), while the 5-year DSS rate was similar between the groups (100% vs. 100%). The mortality rate was significantly higher in ASA-PS 3 patients than in ASA-PS 1/2 patients (hazard ratio 3.47; 95% confidence interval 1.79-6.74; P < 0.01). Death due to exacerbation of comorbidities was significantly more frequent in ASA-PS 3 patients than in ASA-PS 1/2 patients (42.4% vs. 8.3%, P < 0.04). CONCLUSION Because of the exacerbation of comorbidities, patients with severe comorbidities had poorer long-term outcomes after esophageal ESD than those with non-severe comorbidities. Further studies will be necessary to evaluate esophageal ESD in patients with severe comorbidities.

Abstract
Background
The clinical benefits of neurohormonal antagonist in patients with heart failure (HF) with mid-range and preserved ejection fraction (HFmrEF and HFpEF) were uncertain. This study aimed to evaluate the prognostic effect of starting angiotensin-converting enzyme inhibitors (ACE-I) / angiotensin II receptor blockers (ARB) and β-blocker during HF hospitalization in these patients.
Methods
We analyzed 858 consecutive patients with HFmrEF (EF:40–49%) or HFpEF (EF≥50%), who were hospitalized for acute decompensated HF, were discharged alive, and were not taking ACE-I/ARB or β-blockers at admission. The study population was classified into four groups according to the status of prescription of ACE-I/ARB and β-blocker at discharge: no neurohormonal antagonist (N=342, 39.9%), ACE-I/ARB only (N=128, 14.9%), β-blocker only (N=189, 22.0%), and both ACE-I/ARB and β-blocker (N=199, 23.2%) groups. The primary outcome measure was a composite of all-cause death or HF hospitalization.
Results
The cumulative 1-year incidence of the primary outcome measure was 41.2% in the no neurohormonal antagonist group, 34.0% in the ACE-I/ARB only group, 28.6% in the β-blocker only group, and 16.4% in the both ACE-I/ARB and β-blocker group (P<0.001). Compared with the no neurohormonal antagonist group, the both ACE-I/ARB and β-blocker group were associated with a significantly lower risk for a composite of all-cause death or HF hospitalization (HR: 0.59, 95% CI: 0.38–0.91, P=0.02).
Conclusions
In hospitalized patients with HFmrEF and HFpEF, starting both ACE-I/ARB and β-blocker was associated with a reduced risk of a composite of all-cause death or HF hospitalization compared with not starting ACE-I/ARB or β-blocker.

Abstract
Simple Summary Pancreatic cancer (PC) has a poor prognosis; however, diagnosing PC at an earlier stage could improve long-term patient outcomes. Endoscopic ultrasonography (EUS) plays an important role in PC detection, and the indirect findings (caliber change, retention cysts, and dilatation of the branch duct) that are detected by EUS are especially important for the early detection of PC. The aim of this retrospective study was to compare the diagnostic efficacy of radial- and convex-arrayed echoendoscope for the detection rate of indirect findings. As a result, the radial-arrayed echoendoscope was found to be an independent detection factor of indirect findings by multivariate analysis. The radial-arrayed echoendoscope is useful for the detection of indirect findings. Abstract Endoscopic ultrasonography (EUS) is useful for detecting early-stage pancreatic cancer. Because the detection of small lesions is difficult, it is important to detect indirect findings, namely caliber change, retention cysts, and dilatation of the branch duct, during the procedure. Although two types of EUS endoscopes are frequently used, there is no comparative study on their efficacy for detecting indirect findings. Therefore, we aimed to compare the diagnostic efficacy of these two types for indirect findings. We retrospectively analyzed 316 consecutive patients who had undergone EUS for pancreaticobiliary disease at a single center between January 2017 and December 2018. The main outcome was the detection rate of indirect findings and its comparison between the two echoendoscope types. This outcome was achieved using the inverse probability of treatment weighting (IPTW) analysis. The detection rate of indirect findings was higher for the radial-arrayed endoscope than for the convex-arrayed echoendoscope (9.2% vs. 2.3% (p = 0.02)). The univariate analysis also revealed that the radial-arrayed echoendoscope was significantly superior to the convex-arrayed echoendoscope in terms of the detection of indirect findings (odds ratio, 5.94; 95% confidence interval, 1.68–21.10; p = 0.01) after IPTW. After adjustment for magnetic resonance imaging (MRI) and computed tomography (CT), radial-arrayed echoendoscope remained an independent factor for indirect finding detection (odds ratio, 6.04; 95% confidence interval, 1.74–21.00; p = 0.01). Finally, five patients who had indirect EUS findings were diagnosed with pancreatic cancer. Our results indicate that the radial-arrayed echoendoscope is useful for the detection of indirect findings.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) induce small intestinal damage. It has been reported that rebamipide, a mucoprotective drug, exerts a protective effect against NSAID-induced small intestinal damage; however, the underlying mechanism remains unknown. In this study, we investigated the significance of the small intestinal microbiota in the protective effect of rebamipide against indomethacin-induced small intestinal damage in mice. A comprehensive analysis of the 16S rRNA gene sequencing revealed an alteration in the composition of the small intestinal microbiota at the species level, modulated by the administration of rebamipide and omeprazole. The transplantation of the small intestinal microbiota of the mice treated with rebamipide suppressed the indomethacin-induced small intestinal damage. Omeprazole, a proton pump inhibitor, exacerbated the indomethacin-induced small intestinal damage, which was accompanied by the alteration of the small intestinal microbiota. We found that the transplantation of the small intestinal microbiota of the rebamipide-treated mice ameliorated indomethacin-induced small intestinal damage and the omeprazole-induced exacerbation of the damage. These results suggest that rebamipide exerts a protective effect against NSAID-induced small intestinal damage via the modulation of the small intestinal microbiota, and that its ameliorating effect extends also to the exacerbation of NSAID-induced small intestinal damage by proton pump inhibitors.

Abstract
BACKGROUND Little is known about the efficacy of proton-pump inhibitor (PPI) therapy in the management of esophageal ulcers after endoscopic submucosal dissection (ESD). Therefore, the objective of this study was to investigate the efficacy of PPI in ulcer healing following ESD for superficial esophageal neoplasms, using a propensity score analytic approach. METHODS This retrospective cohort study was conducted at a single referral center. Between April 2005 and August 2015, 199 consecutive patients with superficial esophageal cancer and esophageal dysplasia underwent ESD. For patients with PPI administration, intravenous PPI therapy was commenced immediately after ESD, and oral PPI was administered daily from post-operative day 3, until ulcer healing was identified. We compared the remnant-ulcer rate at 4 weeks after esophageal ESD between the PPI administration and non-PPI groups, using propensity scores and the inverse probability of treatment weighting (IPTW) method. RESULTS After exclusions, a total of 88 patients were analyzed. The remnant-ulcer rate at 4 weeks after ESD was 25.5% (12/47) and 14.6% (6/41) in the PPI administration and non-PPI groups (p = 0.21). After adjusting for background factors using IPTW, the risk of a remnant ulcer in the PPI administration group was not decreased significantly compared with that in the non-PPI group [odds ratio (OR) = 2.42, 95% confidence interval (CI): 0.73-7.97, p = 0.15]. Furthermore, PPI therapy did not decrease significantly the remnant-ulcer rate on logistic regression analysis after adjusting for the propensity score (OR = 2.40, 95% CI: 0.69-8.32, p = 0.15). CONCLUSION PPI administration does not promote ulcer healing after ESD for superficial esophageal squamous cell carcinoma.

Abstract
BACKGROUND AND AIM Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) remains the most common and serious adverse event associated with ERCP. Risk factors for PEP have been described in various reports. However, risk factors have not been quantified to date. The aim of this study was to investigate the risk factors for PEP by quantification of pancreatic volume using pre-ERCP images. METHODS Overall, 800 patients were recruited from April 2012 to February 2015 for this study. There were 168 patients who satisfied the inclusion criteria. Measurement of pancreatic volume was achieved using the volume analyzer SYNAPSE VINCENT in all cases and was used to evaluate the risk factors for PEP. RESULTS According to the criteria established by the consensus guidelines (Cotton classification), 17 patients (10.1%) were classified as having mild disease, 4 (2.4%) as having moderate disease, and 5 (3.0%) as having severe disease. Multivariate model analysis showed that a large pancreatic volume was a significant risk factor for PEP (odds ratio [OR] 1.10, 95% confidence interval [CI] 1.06-1.13; P < 0.001). In addition, the association between the pancreatic volume and the severity of PEP was positively correlated (the effect of volume [per 1 mL]; OR 1.09, 95% CI 1.07-1.12; P < 0.001, the effect of volume [per 10 mL]; OR 2.27, 95% CI 1.72-3.00; P < 0.001). A larger pancreatic volume was significantly associated with a higher incidence of PEP. CONCLUSIONS A large pancreatic volume was identified as a risk factor for PEP. The results of this study suggest that pre-ERCP images might be useful for predicting PEP.

Abstract
INTRODUCTION Both infliximab (IFX) and tacrolimus (Tac) are effective for inducing clinical remission in patients with ulcerative colitis (UC). However, no randomized study has addressed the relative efficacies of IFX and Tac for patients with moderate to severe UC. This study aimed to conduct a retrospective study on the relative efficacy of IFX and Tac in patients with moderate to severe UC, using an inverse probability of treatment weighting (IPTW) technique to adjust background factors statistically. METHODS Between July 2009 and March 2016, data obtained from 122 patients with moderate to severe UC who were treated with either IFX (n = 58) or Tac (n = 64) were analyzed retrospectively. We compared the short-term therapeutic efficacy between the IFX group and Tac group using IPTW technique. RESULTS The clinical remission rate at 14 weeks after treatment was 37.9% (22/58) in the IFX group and 50% (32/64) in the Tac group, respectively. The efficacy of IFX and Tac for clinical remission rate was not different according to univariate (Odds ratio [OR] 1.64, 95% confidence interval [CI] 0.80-3.37 P = 0.18) and multivariate analyses (OR 2.19, 95% CI 0.85-5.61, P = 0.10). After the background and confounders factors were adjusted by using IPTW based on propensity score, the efficacy of IFX and Tac for clinical remission rate was not differed statistically (OR, 1.483; 95% CI, 0.581-3.785; P = 0.409) Conclusion. IFX and Tac have equivalent short-term efficacies for induction in patients with moderate to severe UC.

Abstract
OBJECTIVES The American and Japanese Societies for Gastrointestinal Endoscopy Guidelines recommend heparin-bridging therapy for patients whose oral anticoagulants are interrupted for endoscopic procedures. However, little is known about the potential association between heparin-bridging therapy and post-polypectomy bleeding (PPB). The aim was to investigate the incidence of PPB associated with heparin-bridging therapy administered to patients whose anticoagulants were interrupted. MATERIALS AND METHODS This was a retrospective observational study using inverse propensity analysis. Between 2013 and 2015, 1004 patients with 2863 lesions were included. The primary outcomes were the rates of PPB and thromboembolism associated with heparin-bridging therapy. The risk factors associated with PPB were identified using multivariate logistic regression analysis involving probability of treatment weighting (IPTW). RESULTS The patients were categorized into a heparin-bridging therapy group (78 patients with 255 lesions) or a control group (926 patients with 2608 lesions). The PPB rate in the heparin-bridging therapy group (10.2%, 8/78) was significantly higher than in the control group (1.1%, 11/926) (p <.01). Thromboembolism occurred in one patient in the control group. The multivariate analysis revealed that heparin-bridging therapy was an independent risk factor associated with PPB (odds ratio [OR], 8.21; 95% confidence interval [95% CI], 2.32-29.10; p <.01). IPTW showed heparin-bridging therapy increased PPB (OR, 7.68; 95% CI, 1.83-32.28; p <.01). CONCLUSIONS Heparin-bridging therapy administered to patients whose oral anticoagulants were interrupted was associated with an increased PPB risk.

Abstract
BACKGROUND AND AIMS It is believed that preoperative biopsy sampling for superficial-type colorectal tumors should be avoided because submucosal fibrosis caused by biopsy sampling makes EMR impossible. However, few studies have reported the influence of biopsy sampling on colorectal endoscopic submucosal dissection (ESD). This study aimed to examine the effect of biopsy sampling on submucosal fibrosis and treatment outcomes of ESD for laterally spreading tumors (LSTs). METHODS Between April 2005 and September 2015, 441 consecutive patients underwent colorectal ESD in Osaka City University Hospital. Using propensity score matching and inverse probability of treatment weighting (IPTW), we retrospectively evaluated risk factors for severe submucosal fibrosis and treatment outcomes for patients with LSTs, with or without preoperative biopsy sampling. RESULTS A total of 428 LSTs resected using ESD were enrolled. After matching, there were 136 matched pairs of lesions that did or did not undergo biopsy sampling. Preoperative biopsy sampling increased severe fibrosis compared with that in the non-biopsy sampling group (20.6% vs 11.0%; P = .03) and was significantly associated with severe fibrosis after matching (odds ratio [OR], 2.09; 95% confidence interval [CI], 1.07-4.10; P = .03). After adjustment with IPTW, biopsy sampling also increased the risk of severe fibrosis (OR, 2.33; 95% CI, 1.17-4.63; P = .02). However, no significant differences were observed between the 2 groups in treatment outcomes. CONCLUSIONS Preoperative biopsy sampling for colorectal LSTs might cause severe submucosal fibrosis but has no adverse influence on clinical outcomes of ESD.

Abstract
Gliadin, a component of wheat gluten known to be an important factor in the etiology of celiac disease, is related to several other diseases through its enhancing effect on intestinal paracellular permeability. We investigated the significance of gliadin in non-steroidal anti-inflammatory drug (NSAID)-induced small-intestinal damage in mice. 7-week-old C57BL/6 male mice were divided into the following groups: standard diet group, in which mice were fed with wheat-containing standard rodent diet (CE-2); gluten-free diet group, in which mice were fed with gluten-free diet (AIN-76A); and gliadin-administered group, in which mice fed with gluten-free diet were administered with gliadin (~250 mg/kg BW). Each group was subdivided into negative, healthy control group and NSAID-treated group. To some mice fed with gluten-free diet and administered with gliadin, epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was administered for clarification of the significance of EGFR in NSAID-induced small intestinal damage and intestinal permeability. In mice fed with a gluten-free diet, indomethacin or diclofenac induced very mild mucosal damage in the small intestine compared with that in mice fed with a wheat-containing standard diet. Gliadin exacerbated the NSAID-induced small-intestinal damage in mice fed with a gluten-free diet. With the administration of indomethacin, MPO activity, a marker of neutrophil infiltration into the mucosa and mRNA expression level of tumor necrosis factor α and interleukin-1β in the small intestine were higher in the gliadin-administered mice. Gliadin increased the intestinal paracellular permeability without indomethacin administration (4.3-fold) and further increased the permeability after indomethacin administration (2.1-fold). Gliadin induced phosphorylation of epidermal growth factor receptor (EGFR) in small-intestinal tissues, and erlotinib (an EGFR tyrosine kinase inhibitor) attenuated the indomethacin-induced intestinal damage and permeability exacerbated by gliadin, accompanied by inhibition of EGFR phosphorylation. These results suggest that gliadin plays an important role in the induction and exacerbation of NSAID-induced small-intestinal damage, and that increase in intestinal permeability via the EGFR signalling pathway is involved in its mechanism.

Abstract
BACKGROUND Adenocarcinoma of the esophagogastric junction (EGJ) is uncommon in Eastern countries, including Japan, but it is believed that the incidence of EGJ adenocarcinoma will increase in Asia in the future due to the decreasing incidence of Helicobacter pylori infection. Endoscopic submucosal dissection (ESD) is a minimally invasive and curative treatment that allows precise pathological assessment. SUMMARY Magnifying endoscopy with narrow-band imaging may be useful for differential diagnoses and for delineating the cancer margin of EGJ adenocarcinoma, but subsquamous carcinoma extension, which is the invasion of EGJ adenocarcinoma beneath the normal esophageal squamous epithelium, makes it difficult to detect cancer margins of the oral side in ESD for EGJ adenocarcinoma. Since subsquamous carcinoma extension was reported to be less than 1 cm in most cases, the oral safety margin that is placed 1 cm from the squamocolumnar junction is useful for negative cancerous horizontal margin. A multicenter retrospective study of esophageal adenocarcinoma including EGJ adenocarcinoma showed that mucosal and submucosal cancer within 500 μm from the muscularis mucosa without lymphovascular involvement, a poorly differentiated component, and lesion size over 3 cm were not associated with metastasis. Several retrospective studies about ESD for EGJ adenocarcinoma have suggested feasible short-term and long-term outcomes using curative criteria based on gastric cancer guidelines. Key Messages: ESD would be a good first-line treatment for superficial EGJ adenocarcinoma, including Barrett's adenocarcinoma. Additional information about the incidence of metastasis would help confirm the indication of ESD for EGJ adenocarcinoma.

Abstract
BACKGROUND Obscure gastrointestinal bleeding (OGIB) is a common but embarrassing problem for gastroenterologists. Most bleeding lesions associated with OGIB are present in the small intestine and sometimes cannot be identified due to the difficulty associated with physical accessibility. Capsule endoscopy (CE) and double-balloon enteroscopy (DBE) have enabled in the process of diagnosing and have evolved to become approaches to treating OGIB. SUMMARY CE is a minimally invasive procedure and has a high diagnostic yield in patients with OGIB. DBE offers additional advantage of biopsy collection for pathological diagnosis and therapeutic intervention, but it should be noted that it sometimes causes severe adverse events such as acute pancreatitis, intestinal bleeding, and intestinal perforation. CE should be performed early in the workup course of OGIB. Positive CE findings enhance the diagnostic yield of subsequent DBE, and the effective therapeutic intervention improves the clinical outcomes of OGIB patients. On the contrary, there are no clear guidelines for further investigation of patients with negative CE findings at the present. Although patients in stable general condition may only require follow-up, repeated CE is useful to detect positive findings in patients with evidence of sustained bleeding and progressing anemia. We have revealed that repeated CE has higher positive finding rate than DBE in OGIB patients with negative CE findings in a preliminary study. Key Messages: CE and DBE have complementary roles in the management of OGIB, and the precise timing and proper sequence may be important for the approach to treating OGIB.

Abstract
Background Incomplete polyp resection during colorectal endoscopic mucosal resection (EMR) might contribute to the development of interval cancer. Objective This retrospective study aimed to determine the incidence of incomplete polyp resection during EMR of colorectal polyps located across a fold compared with that of colorectal polyps located between folds. Methods In total, 262 patients with 262 lesions that were ≥10 mm in diameter and treated with conventional EMR were enrolled. The main outcome was the incidence of incomplete polyp resections. Propensity score matching and inverse probability of treatment weighting (IPTW) were performed to reduce the effects of selection bias. Results Fifty-seven lesions (21.8%) were incompletely resected. After propensity score matching, the lesions located across a fold were at higher risk of incomplete resection than those between folds (26/68, 38.2% vs 7/68, 10.3%; odds ratio (OR): 3.71; 95% confidence interval (CI): 1.61-8.56; p < 0.01). These findings persisted after adjusting for the differences at baseline using the IPTW method (OR: 3.63; 95% CI: 1.72-7.63; p = 0.001). Conclusions There is an increased risk of an incomplete polyp resection for a colorectal polyp that is located across a fold compared with that for a polyp that is located between folds.

Abstract
Background Although capsule endoscopy (CE) is a noninvasive diagnostic tool for patients with obscure gastrointestinal bleeding (OGIB), bleeding lesions are often not detected. No strategies have been established to determine whether CE or double-balloon enteroscopy (DBE) should be performed after negative CE. Methods Among 652 patients who underwent CE for OGIB, a total of 359 patients had negative findings. Of these, 41 and 48 patients underwent repeat CE and DBE for small bowel reexamination, respectively. We compared the rate of positive findings between the two groups. The findings were considered positive if mucosal break, vascular lesion, tumor, or active bleeding was observed. Results The rate of positive findings in the repeat CE group was significantly higher than that in the DBE group (73.2% vs. 39.6%; p = 0.001). Logistic regression analysis showed that the repeat CE group was significantly associated with positive findings (odds ratio (OR), 4.2; 95% confidence interval (CI), 1.7-10.2; p = 0.002). Inverse probability of treatment-weighted analysis revealed that repeat CE was significantly associated with positive findings (OR, 4.4; 95% CI, 1.6-12.2; p = 0.004). Conclusions Reexamination via CE appears to have more diagnostic value than DBE for OGIB patients with negative CE findings.

Abstract
BACKGROUND Little is known about the prevalence and pathogenicity of human herpes viruses except for cytomegalovirus (CMV) in patients with inflammatory bowel disease (IBD). The aim of this study was to determine the prevalence of human herpes viruses on colonic mucosa in patients with IBD and assess the long-term outcomes in these patients. METHODS We examined the colonic mucosal specimens from 66 patients with ulcerative colitis (UC), 54 patients with Crohn's disease (CD), and 29 healthy patients to identify the 6 most common types of human herpes virus, using multiplex polymerase chain reaction (PCR) technique. RESULTS Herpes simplex virus (HSV)-1/2 and varicella-zoster virus (VZV) were not detected in any of the groups. There was a higher prevalence of Epstein-Barr virus (EBV) (21.2%) and CMV (15.1%) in patients with UC than in patients with CD (EBV 9.3%, CMV 0%) and patents in the healthy control group (EBV 0%, CMV 3.4%). The prevalence of human herpes virus (HHV)-6A/B and HHV-7 was not statistically different among the groups. Five UC patients with inflammation had coexisting CMV and EBV or HHV-6. The combined infection of CMV with EBV or HHV-6 was a significant and independent prognostic factor for subsequent colectomy in patients with UC. CONCLUSIONS The increased prevalence of CMV coexisting with EBV/HHV-6 infection was associated with the clinical course in patients with UC. 10.1093/ibd/izy005_video1izy005_Video_15786489376001.

Abstract
BACKGROUND AND AIM Esophageal endoscopic submucosal dissection (ESD) to resect widespread lesions has increased the incidence of strictures, and some patients develop strictures despite receiving prophylactic locoregional triamcinolone injections. The present study evaluated the predictive factors for esophageal stricture formation in patients given prophylactic triamcinolone injections after ESD. METHODS This was a retrospective observational study. Of 552 consecutive patients who underwent ESD, those who received prophylactic triamcinolone injections immediately after ESD were enrolled. Primary outcome was predictive factors for esophageal stricture formation in patients given prophylactic triamcinolone injections. RESULTS We evaluated 101 en bloc resections involving 144 lesions in 96 patients. Strictures occurred following 17 (16.8%) resections. Wider circumferential mucosal defect (odds ratio [OR] 2.42, 95% confidence interval [CI]: 1.01-5.80; P = 0.048) was an independent predictive factor for stricture development. Cut-off value associated with stricture formation was five-sixths of the circumferential mucosal defect. Propensity analysis determined that frequency of esophageal strictures increased in patients with circumferential mucosal defects of more than five-sixths compared with those less than five-sixths (OR = 5.70, 95% CI: 1.61-20.18; P = 0.007). CONCLUSION Resections involving circumferential mucosal defects of more than five-sixths increased the likelihood of stricture formation in patients given prophylactic locoregional triamcinolone injections after esophageal ESD.

Abstract
BACKGROUND AND AIM Secondary loss of response to adalimumab (ADA-LOR) commonly occurs in patients with Crohn's disease (CD) treated with adalimumab (ADA). We evaluated the efficacy of concomitant elemental diet (ED) therapy to reduce ADA-LOR in adult CD patients. METHODS Patients were divided into either an ED (≥900 kcal/day) or a non-ED group (<900 kcal/day). Cumulative non-ADA-LOR rates were compared between groups. The effects of ED intake to reduce ADA-LOR were also assessed in antitumor necrosis factor-alpha (TNF-α)-naïve and infliximab (IFX)-intolerant or refractory CD patients. Serum ADA and TNF-α levels were measured. RESULTS We enrolled 117 CD patients into the ED (n = 25) or non-ED (n = 92) groups. Although the cumulative non-ADA-LOR rate was higher in the ED group than in the non-ED group, ED intake was not an independent reducing factor for ADA-LOR (adjusted hazard ratio = 0.725; 95% confidence interval: 0.448-1.180; P = 0.196) in all patients. ED intake was significantly more effective in reducing ADA-LOR in IFX-intolerant or refractory patients than in anti-TNF-α-naïve patients in a dose-related manner (P for interaction <0.20). Serum ADA levels did not differ between the groups. Serum TNF-α levels were significantly lower in the ED group than in the non-ED group at week 28 (P = 0.044) and week 52 (P = 0.043). CONCLUSIONS Concomitant ED therapy reduced ADA-LOR in IFX-intolerant or refractory patients in a dose-related manner. Reductions in the TNF-α levels by concomitant ED intake may contribute to reduce ADA-LOR in CD patients.

Abstract
BACKGROUND Interruption of sedation due to a poor response to modified neuroleptanalgesia (m-NLA) with midazolam often occurs during endoscopic submucosal dissection (ESD) for esophageal squamous cell carcinoma (ESCC) because most patients have a history of heavy alcohol intake. Recently, propofol has been used feasibly and safely during endoscopic procedures. The aim of this study was to clarify the efficacy and safety of propofol compared with that of midazolam during ESD for ESCC. METHODS This was a single-blind, randomized controlled trial in a single center. Patients with ESCC scheduled for ESD were included in the study. Patients were randomly assigned to one of two groups: the propofol group and the midazolam group. The main outcome was the incidence of discontinuation of the procedure due to a poor response to sedation. Secondary outcomes included risk factors for a poor response to sedation. RESULTS Between April 2014 and October 2015, 132 patients (n = 66 per group) who underwent ESD for ESCC were enrolled in this study. The incidence of discontinuation due to a poor response to sedation in the propofol and midazolam groups was 0% (0/66) and 37.9% (25/66), respectively (p < 0.01). Multivariate analyses revealed that use of midazolam [Odds ratio (OR), 7.61; 95% confidence interval (CI), 2.64-21.92; p < 0.01] and age (OR, 0.93; 95% CI, 0.86-0.98; p < 0.01) were risk factors for a poor response to sedation. CONCLUSIONS Our study indicates that, compared with midazolam, propofol is a more efficient sedative for m-NLA during ESD for ESCC.

Abstract
Gastric metastasis from ovarian cancer has rarely been reported. We herein report the case of a 64-year-old woman with gastric metastasis from ovarian cancer that was diagnosed as surgical stage IA. Diagnostic and staging laparotomy showed mucinous carcinoma of the right ovary. At one month after surgery, bone metastasis was detected via scintigraphy. On esophagogastroduodenoscopy, a 10-mm elevated lesion with ulceration on the top was seen in the stomach. The immunohistochemical analysis of biopsy specimens showed that these metastases arose from ovarian cancer. We recommend that physicians remain aware of the possibility of gastric metastasis in patients with ovarian cancer.

Abstract
BACKGROUND & AIMS Advanced techniques have been developed to overcome difficult cannulation cases in endoscopic retrograde cholangiopancreatography (ERCP). Pancreatic duct guidewire placement method (PGW) is performed in difficult cannulation cases; it is possible that it places patients at risk of post-ERCP pancreatitis (PEP). The mechanism of PEP is still unclear, but pancreatic duct pressure and injury of pancreatic duct are known causes of PEP. Therefore, we hypothesized a relationship between pancreatic duct diameter and PEP and predicted that PGW would increase the risk of PEP in patients with non-dilated pancreatic ducts. This study aimed to investigate whether PGW increased the risk of PEP in patients with pancreatic duct diameter ≤ 3 mm. METHODS We analyzed 332 patients with pancreatic duct ≤ 3 mm who performed first time ERCP session. The primary endpoint was the rate of adverse event of PEP. We evaluated the risk of PEP in patients who had undergone PGW compared to those who had not, using the inverse probability of treatment weighting (IPTW) analysis. RESULTS PGW was found to be an independent risk factor for PEP by univariate analysis (odds ratio [OR], 2.45; 95% confidence interval [CI], 1.12-5.38; p = 0.03) after IPTW in patients with pancreatic duct diameter ≤ 3 mm. Adjusted for all covariates, PGW remained an independent risk factor for PEP (OR, 3.12; 95% CI, 1.33-7.33; p = 0.01). CONCLUSION Our results indicate that PGW in patients with pancreatic duct diameter ≤ 3 mm increases the risk of PEP.

Abstract
BACKGROUND AND AIMS Novel noninvasive biomarkers with high diagnostic accuracy are required to assess mucosal healing, which is associated with sustained clinical remission, in inflammatory bowel disease. This study aimed to explore sepsis markers as potential biomarkers for mucosal healing. METHODS Patients with ulcerative colitis [UC] or Crohn's disease [CD], who underwent blood tests for C-reactive protein [CRP], serum procalcitonin [PCT], soluble interleukin-2 receptor [sIL-2R], and plasma soluble CD14 subtype [sCD14-ST] within 2 weeks of endoscopy, were retrospectively recruited; and we assessed the relationship between marker levels and clinical features. Complete mucosal healing [cMH] was defined as a Mayo endoscopic subscore [MES] of 0 for UC and a simple endoscopic score for Crohn's disease [SES-CD] of 0 for CD. RESULTS In all, 68 UC patients and 33 CD patients were included in this study. In patients with UC, the sIL-2R level was significantly higher in patients without cMH than in those with cMH. The sIL-2R level had the highest diagnostic value for identifying cMH in UC. In patients with CD, CRP and sCD14-ST levels were significantly higher in patients without cMH than in those with cMH, and both CRP and sCD14-ST had good diagnostic values for identifying cMH. The sCD14-ST level had a high diagnostic value for identifying cMH even among CD patients with complete clinical remission, defined as a Harvey-Bradshaw index of 0. CONCLUSIONS The sIL-2R and sCD14-ST levels in patients with UC and CD, respectively, can be useful surrogate markers for identifying mucosal healing in inflammatory bowel disease.

Abstract
Background and aims Brushing cytology is useful for diagnosing biliary strictures. With regard to biliary stricture brushing at the distal common bile duct in the surrounding of the papilla, the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis is unknown. Our study aimed to evaluate the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis by using this procedure. Methods A total of 150 endoscopic retrograde cholangiopancreatography-naïve patients undergoing endoscopic retrograde cholangiopancreatography including biliary stricture brushing were retrospectively analyzed. Patients were divided into two groups: the surrounding of the papilla group (n = 25) and the other group (n = 125). The primary outcome was the post-endoscopic retrograde cholangiopancreatography pancreatitis incidence. We analyzed the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis by using inverse probability of treatment weighting based on propensity scores to adjust for selection bias. Results The overall incidence of post-endoscopic retrograde cholangiopancreatography pancreatitis was 11.3%, and post-endoscopic retrograde cholangiopancreatography pancreatitis of the surrounding of the papilla group occurred significantly more frequently than in the other group (32.0% vs 7.2%, p < 0.01). Multivariate analysis showed that this procedure was a risk factor for post-endoscopic retrograde cholangiopancreatography pancreatitis (odds ratio, 10.6; 95% confidence interval, 2.82-40.2; p < 0.01). In the propensity-weighted model, this procedure was an independent risk factor for post-endoscopic retrograde cholangiopancreatography pancreatitis (odds ratio, 8.42; 95% confidence interval, 2.12-32.4; p < 0.01) by multivariate analysis. Conclusions Biliary stricture brushing at the distal common bile duct in the surrounding of the papilla may increase the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis compared with brushing other portions.

Abstract
BACKGROUND Capsule endoscopy (CE) is a useful tool for patients with obscure gastrointestinal bleeding (OGIB), but positive finding rate differs among trials, which may be attributable to the difference in patients' background. OBJECTIVES To evaluate the predictive factors associated with positive findings on CE. METHODS Consecutive patients with OGIB who underwent CE between March 2004 and May 2015 at a single university hospital were enrolled. Patients' clinical factors and CE data were reviewed retrospectively, and we evaluated the relationship between clinical factors and positive findings by univariate and multivariate logistic regression analyses. RESULTS Five hundred and seventy-eight patients were included in the analysis. Positive CE findings were obtained in 284 patients (49.1%). In multivariate analysis, low hemoglobin level (odds ratio (OR), 1.142 per 1 g/dL decrease; p < .001), Charlson comorbidity index (CCI) score (OR, 1.170 per 1 point increase; p = .002), and non-steroidal anti-inflammatory drug (NSAID) use (OR, 1.640; p = .044) were associated with an increased prevalence of positive findings. As for components of CCI, malignant tumor (OR, 1.839; p = .017) was associated with the positive findings. CONCLUSIONS OGIB patient with a low-hemoglobin level, complex and severe comorbidities, and NSAID use should receive CE.

Abstract
Objective Balloon-assisted endoscopy enables access to and treatment of strictures in the small intestine using endoscopic balloon dilation (EBD); however, the long-term outcomes of EBD have not been sufficiently evaluated. This study evaluated the long-term outcomes of EBD in Crohn's disease to identify the risk factors associated with the need for subsequent surgical intervention. Methods We retrospectively analyzed patients with Crohn's disease who had undergone EBD with double-balloon endoscopy (DBE) for small intestinal strictures at a single center between 2006 and 2015. The long-term outcomes were assessed based on the cumulative surgery-free rate following initial EBD. Results Seventy-two EBD with DBE sessions and 112 procedures were performed for 37 patients during this period. Eighteen patients (48.6%) required surgery during follow-up. Significant factors associated with the need for surgery in a multivariate analysis were multiple strictures (adjusted hazard ratio, 14.94; 95% confidence interval, 1.91-117.12; p=0.010). One patient (6.7%) required surgery among 15 who had single strictures compared to 17 (77.3%) among 22 patients with multiple strictures. Conclusion In a multivariate analysis, the presence of multiple strictures was a significant risk factor associated with the need for surgery; therefore, a single stricture might be a good indication for EBD using DBE for small intestinal strictures in Crohn's disease patients.

Abstract
BACKGROUND/AIMS Modified neuroleptanalgesia (m-NLA) with midazolam is often used for sedation and analgesia during endoscopic submucosal dissection (ESD) for gastrointestinal neoplasia. However, interruption due to poor response to midazolam is often experienced during ESD for esophageal squamous cell carcinoma (ESCC) because most patients with ESCC have a history of heavy alcohol intake. We examined the incidence and risk factors for poor response to m-NLA with midazolam and pethidine hydrochloride. METHODS This retrospective cross-sectional study was conducted at a single institution. Between April 2007 and July 2013, 151 patients with superficial ESCC who underwent ESD under sedation using m-NLA with midazolam and pethidine hydrochloride were enrolled. Poor response to sedation was defined as the use of a second drug when Ramsay Sedation Score 1-2. RESULTS Poor response to sedation occurred in 66.2% patients. Most cases of poor response were controlled by using additional flunitrazepam. Multivariate logistic regression analysis showed that cumulative alcohol intake and major specimen size were independent risk factors for poor response to sedation (OR 3.63, 95% CI 1.20-10.99, and OR 3.23, 95% CI 1.26-8.25). CONCLUSION Our study indicated that cumulative alcohol intake and major specimen size were associated with poor response to m-NLA with midazolam and pethidine hydrochloride.

Abstract
BACKGROUND Recently, diagnosis of obscure gastrointestinal bleeding (OGIB) has improved greatly due to introduction of capsule endoscopy (CE) and double balloon enteroscopy (DBE). However, the efficacy of CE over DBE in patients with previous OGIB remains unclear. This study aimed to compare, in terms of diagnostic yield, the efficacy of DBE with that of CE in patients with previous OGIB. PATIENTS AND METHODS We enrolled 223 consecutive patients with previous OGIB who were treated between May 2007 and March 2012. We retrospectively evaluated the respective diagnostic yields of CE and DBE in patients with previous OGIB using propensity score-matching analysis. We compared the diagnostic yield of CE with that of DBE. RESULTS The diagnostic yields were 41.9% in DBE group and 11.6% in CE group, respectively (p < .01). On logistic regression analysis, DBE was significantly superior to CE after matching (Odds ratio [OR], 4.25; 95% confidence interval [CI], 1.43-12.6; p < .01), even after adjustment for propensity score (OR, 5.65; 95% CI, 1.56?20.5; p < .01). CONCLUSIONS Our results indicate that DBE might be more useful and perhaps safer than CE in achieving a positive diagnosis in patients with previous OGIB.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) damage the small intestine by causing multiple erosions and ulcers. However, to date, no established therapies and prophylactic agents are available to treat such damages. We reviewed the role of intestinal microbiota in NSAID-induced intestinal damage and identified potential therapeutic candidates. SUMMARY The composition of the intestinal microbiota is an important factor in the pathophysiology of NSAID-induced small intestinal damage. Once mucosal barrier function is disrupted due to NSAID-induced prostaglandin deficiency and mitochondrial malfunction, lipopolysaccharide from luminal gram-negative bacteria and high mobility group box 1 from the injured epithelial cells activate toll-like receptor 4-signaling pathway and nucleotide-binding oligomerization domain-like receptor family, pyrin domain-containing 3 inflammasome; this leads to the release of proinflammatory cytokines such as tumor necrosis factor-α and interleukin-1β. Proton pump inhibitors (PPIs) are often used for the prevention of NSAID-induced injuries to the upper gastrointestinal tract. However, several studies indicate that PPIs may induce dysbiosis, which may exacerbate the NSAID-induced small intestinal damage. Our recent research suggests that probiotics and rebamipide could be used to prevent NSAID-induced small intestinal damage by regulating the intestinal microbiota. Key Messages: Intestinal microbiota plays a key role in NSAID-induced small intestinal damage, and modulating the composition of the intestinal microbiota could be a new therapeutic strategy for treating this damage.

Abstract
Objectives Neutrophil-to-lymphocyte ratio (NLR) has been used to determine the outcome in malignancies and coronary heart disease. Some reports considered the value of NLR as a predictor of response to infliximab in patients with Crohn’s disease or rheumatoid arthritis; however, no similar studies have been reported for ulcerative colitis (UC). This study aimed to evaluate the clinical significance of the baseline NLR in patients with UC treated by infliximab. Materials and Methods Patients with moderate-to-severe active UC who received the first infliximab infusion in our hospital between 2010 and 2015, who showed clinical response during the induction period, were retrospectively evaluated for long-term outcomes and risk factors for loss of response (LOR) during infliximab maintenance therapy. Baseline inflammatory markers including NLR were measured within one week before the initiation of infliximab. Results Fifty-nine patients with moderate-to-severe active UC started treatment with infliximab and 37 patients (62.7%) experienced clinical response after induction therapy. Fourteen of 37 patients on maintenance therapy lost the response during follow-up. Baseline NLR of patients with LOR was significantly higher than in patients with sustained response. The NLR cut-off value of 4.488 was predictive of LOR, using receiver operating characteristic analysis (sensitivity: 78.6%, specificity: 78.3%). A univariate analysis revealed a significant relationship between relapse-free survival and the NLR (P = 0.018). Multivariate analysis indicated the NLR as an independent prognostic factor for LOR (hazard ratio = 3.86, 95% confidence interval: 1.20–12.4, P = 0.023). Conclusions Baseline NLR is a useful prognostic marker in patients with moderate-to-severe active UC treated with infliximab, and may contribute to appropriate use of infliximab.

Abstract
The inflammasomes induce maturation of pro-interleukin-1β (IL-1β) and pro-IL-18. We investigated roles of the NLRP3 inflammasome in the pathogenesis of ulcerative colitis (UC). After induction of oxazolone-induced colitis, a mouse UC model, colonic tissues were assayed for inflammatory mediators. Histological studies were performed on inflamed colonic tissue from mice and UC patients. Histological severity of murine colitis peaked on day 1, accompanied by an increase in the expression of Th2 cytokines including IL-4 and IL-13. Oxazolone treatment stimulated maturation of pro-caspase-1 and pro-IL-1β, while it reduced IL-18 expression. Either exogenous IL-1β or IL-18 ameliorated the colitis with or without reduction in Th2 cytokine expression, respectively. Induction of colitis decreased MUC2 expression, which was reversed by administration of IL-18, but not IL-1β. Compared to wild-type mice, NLRP3−/− mice exhibited higher sensitivity to oxazolone treatment with enhancement of Th2 cytokine expression and reduction of mature IL-1β and IL-18 production; this phenotype was rescued by exogenous IL-1β or IL-18. Immunofluorescent studies revealed positive correlation of NLRP3 expression with disease severity in UC patients, and localization of the inflammasome-associated molecules in macrophages. The NLRP3 inflammasome-derived IL-1β and IL-18 may play a protective role against UC through different mechanisms.

Abstract
BACKGROUND Recent studies suggest that chronic inflammation-associated cancer is relevant to microbiome. Esophageal adenocarcinoma arises from an inflammatory condition called Barrett's esophagus, which is caused by gastroesophageal reflux. We hypothesized that esophageal microbiome plays a role in carcinogenesis of esophageal adenocarcinoma. AIM We investigated whether alteration of microbiome using antibiotics affects the development of esophageal adenocarcinoma in a rat model. METHODS Seven-week-old male Wistar rats which had undergone esophagojejunostomy were divided into control (n = 21) and antibiotic groups (n = 22) at 21 weeks after surgery. Control animals were given drinking water, while the other group was given penicillin G and streptomycin in drinking water until rats were killed at 40 weeks after operation. Incidence rates of Barrett's esophagus and adenocarcinoma in each group were evaluated by histological analysis. DNA was extracted from a portion of the distal esophagus, and the microbiome was investigated using terminal restriction fragment length polymorphism (T-RFLP) analysis. RESULTS All rats in both groups developed Barrett's esophagus. Incidence of esophageal adenocarcinoma was similar between both groups with a trend to reduced incidence in the antibiotics group (89 % in the control group, 71 % in the antibiotics group, P = 0.365). T-RFLP analysis showed that esophageal microbiome was different between two groups such as the proportion of Lactobacillales was lower in the antibiotics group and Clostridium cluster XIVa and XVIII was higher in the antibiotics group. CONCLUSIONS Alteration of microbiome does not affect the incidence of esophageal adenocarcinoma. Microbiome may not contribute to the development of esophageal adenocarcinoma.

Abstract
Background Several studies have reported a significant association between sleep disturbance and inflammatory bowel disease (IBD). The aim of the present study is to compare the clinical characteristics and the health-related quality of life (HR-QOL) of Japanese IBD patients with or without sleep disturbances, and to investigate the risk factors for disease flare in these patients. Methods IBD patients were asked to complete a self-administered questionnaire including the Pittsburg sleep quality index and the 8-item short-form health survey. The information about disease flare within 1 year from enrollment in the study was analyzed with a multiple logistic regression model to identify risk factors for IBD flare-ups. Results The prevalence of sleep disturbances was 44.1 % (60 out of 136 IBD patients). Use of sleep medications was significantly higher in IBD patients with sleep disturbances whereas use of immuno modulators was significantly higher in IBD patients without sleep disturbances. The scores from all HR-QOL domains were significantly lower in patients with sleep disturbances than in patients without sleep disturbances. Fifty-one patients (37.5 %) had disease flare within 1 year from enrollment in the study and sleep disturbances were identified as a significant risk factor for disease flare (OR 3.09, 95 % CI 1.47–6.43). Conclusions Our results indicate that sleep disturbances are common in Japanese IBD patients and are associated with poorer HR-QOL. Since the presence of sleep disturbances is a significant risk factor for IBD flare-ups, we encourage physicians to perform a careful examination of sleep disturbances in IBD patients.

Abstract
INTRODUCTION Ileal duplications are encountered infrequently in adults, because symptoms including abdominal pain, intussusception, hemorrhage, and perforation usually present in early childhood. In this report, we present an adult case of ileal duplication that was revealed by double-balloon endoscopy (DBE). CASE DESCRIPTION A 73-year-old Japanese man presented with anemia and melena. Anal DBE detected the narrow opening of an extra lumen in the ileum about 100 cm proximal to the ileocecal valve. Enteroclysis via DBE showed a 5-cm-long ileal diverticulum-like structure at the mesenteric side of the ileum. No ectopic gastric mucosa was detected by technetium-99m pertechnetate scintigraphy. The final diagnosis was ileal duplication. DISCUSSION AND EVALUATION This is the first report of tubular ileal duplication diagnosed by using DBE. The small intestinal duplication opening was not detected by using VCE and plane CT in this case, but was found by using DBE. CONCLUSIONS The present case demonstrates that DBE was useful in the diagnosis of an adult small intestinal duplication that was not visualized by other modalities.

Abstract
The inflammasome is a large, multiprotein complex that consists of a nucleotide-binding oligomerization domain-like receptor (NLR), an apoptosis-associated speck-like protein containing a caspase recruitment domain, and pro-caspase-1. Activation of the inflammasome results in cleavage of pro-caspase-1 into cleaved caspase-1, which promotes the processing of pro-interleukin (IL)-1β into mature IL-1β. We investigated the effects of colchicine on non-steroidal anti-inflammatory drug (NSAID)-induced small intestinal injury and activation of the NLR family pyrin domain-containing 3 (NLRP3) inflammasome. Colchicine treatment inhibited indomethacin-induced small intestinal injury by 86% (1 mg/kg) and 94% (3 mg/kg) as indicated by the lesion index 24 h after indomethacin administration. Colchicine inhibited the protein expression of cleaved caspase-1 and mature IL-1β, without affecting the mRNA expression of NLRP3 and IL-1β. Although treatment with recombinant IL-1β (0.1 μg/kg) did not change the severity of small intestinal damage, the preventive effects of colchicine were abolished by supplementation with the same dose of recombinant IL-1β. Indomethacin-induced small intestinal damage was reduced by 77%, as determined by the lesion index in NLRP3−/− mice, and colchicine treatment failed to inhibit small intestinal damage in NLRP3−/− mice. These results demonstrate that colchicine prevents NSAID-induced small intestinal injury by inhibiting activation of the NLRP3 inflammasome.

Abstract
BACKGROUND AND STUDY AIM The incidence of stricture formation caused by endoscopic submucosal dissection (ESD) for widespread lesions is high, and stricture formation can reduce quality of life. We evaluated the prophylactic efficacy of hybrid therapy using a locoregional steroid injection and polyglycolic acid (PGA) sheets with fibrin glue to prevent stricture formation after esophageal ESD in high risk patients in whom we predicted stricture formation would be difficult to prevent with a single prophylactic steroid injection. METHODS Ten patients who underwent esophageal ESD were enrolled (entire-circumference: n = 6; sub-circumference, more than 5/6 of the circumference: n = 4). A single locoregional steroid injection and PGA sheets with fibrin glue were used after ESD. We evaluated the incidence of stricture formation, the number of endoscopic balloon dilation (EBD) procedures needed to treat the stricture formation, and adverse events of the therapy. RESULTS Esophageal stricture formation occurred in 50.0 % of patients (5/10) (median EBD sessions 0.5, range 0 - 16). Subanalysis showed that stricture formation occurred in 37.5 % of patients (3/8) excluded the lesions located near a previous scar from ESD or surgical anastomosis site (median EBD sessions 0, range 0 - 4). CONCLUSION Hybrid therapy using a locoregional steroid injection and PGA sheets with fibrin glue may have the potential to prevent esophageal stricture formation after esophageal ESD in high risk patients.
