Abstract
A 70-year-old man was admitted to our hospital for the treatment of a large granular-type laterally spreading tumor in the splenic flexure of the descending colon. The preoperative diagnosis was intramucosal colon carcinoma and endoscopic submucosal dissection was performed. During treatment, a small perforation occurred accidentally. After conservative treatment with endoscopic suturing, the patient was discharged without additional surgery. The pathological diagnosis was an intramucosal carcinoma. One year after treatment, no local recurrence was observed on endoscopy, and abdominal computed tomography showed no obvious metastasis. Two years later, fluorodeoxyglucose-positron emission tomography/computed tomography, laparoscopic findings, and histopathologic findings by experimental excision of omentum revealed several disseminated peritoneal metastases from previously treated colon carcinoma. To the best of our knowledge, this is the first report of peritoneal dissemination after a small perforation during endoscopic submucosal dissection and conservative therapy for early-stage colon carcinoma. This report suggests the possibility of tumor dissemination in patients with small perforations during endoscopic procedures. Endoscopists should be aware of these rare potential risks and perform later surveillance carefully.

Abstract
A persistent left superior vena cava (PLSVC) is a commonly observed anatomical anomaly that is frequently detected incidentally via computed tomography (CT) imaging. However, the occurrence of a PLSVC with a right superior vena cava (RSVC) defect, also known as "isolated PLSVC," is a much rarer anomaly. This peculiar malformation can lead to sinoatrial dysfunction, thus necessitating pacemaker implantation, which requires delicate manipulation due to various anatomical complexities. We herein present a case of a sick sinus syndrome with this rare anomaly, which required special consideration when performing pacemaker lead placement.

Abstract
An 83-year-old male underwent three transgastric punctures with endoscopic ultrasound-guided fine-needle aspiration for the examination of a pancreatic body tumor. After a diagnosis of resectable pancreatic cancer and undergoing distal pancreatectomy, the patient was administered postoperative adjuvant chemotherapy with oral S-1 for 6 months, and carcinoembryonic antigen and carbohydrate antigen 19-9 levels were bimonthly evaluated. Carbohydrate antigen 19-9 levels continually increased to 4638.1 U/mL at 45 months post-fine-needle aspiration. Endoscopic ultrasound-guided showed a 25 mm low-echoic, irregularly shaped, and heterogeneous tumor with clear margins protruding from the mucosa outside the gastric wall, and biopsy confirmed adenocarcinoma. Since the immunostaining findings of the specimen matched those of the previously resected specimen, needle tract seeding (NTS) due to puncture of the pancreatic cancer was identified as the cause. After a pylorus-preserving gastrectomy at 46 months post-fine-needle aspiration, postoperative chemotherapy initiation, comprising gemcitabine and nab-paclitaxel, was initiated; however, the patient died despite these interventions as he developed multiple peritoneal dissemination. Although rare, the incidence of NTS will increase in the future owing to the expected extended survival in post-pancreatic cancer resection cases. We suggest regular upper gastrointestinal endoscopy and endoscopic ultrasound-guided evaluations for patients who are at risk for NTS can facilitate early detection. Furthermore, it is extremely relevant to share experiences of encountered NTS cases in practice and extend knowledge of its varying endoscopic appearances.

Abstract
OBJECTIVES The incidence of colorectal neuroendocrine tumors (NETs) has increased with colorectal cancer screening programs and increased colonoscopies. The management of colorectal NETs has recently shifted from radical surgery to endoscopic resection. We aimed to evaluate the short-term outcomes of various methods of endoscopic resection for colorectal NETs. METHODS Among those registered in the C-NET STUDY, patients with colorectal NETs who underwent endoscopic treatment as the initial therapy were included. Short-term outcomes, such as the en bloc resection rate and R0 resection (en bloc resection with tumor-free margin) rate, were analyzed based on treatment modalities. RESULTS A total of 472 patients with 477 colorectal NETs received endoscopic treatment. Of these, 418 patients with 421 lesions who met the eligibility criteria were included in the analysis. The median age of the patients was 55 years, and 56.9% of them were men. The lower rectum was the most commonly affected site (88.6%), and lesions <10 mm accounted for 87% of the cases. Endoscopic submucosal resection with a ligation device (ESMR-L, 56.5%) was the most common method, followed by endoscopic submucosal dissection (ESD, 31.4%) and endoscopic mucosal resection using a cap (EMR-C, 8.5%). R0 resection rates <10 mm were 95.5%, 94.8%, and 94.3% for ESMR-L, ESD, and EMR-C, respectively. All 16 (3.8%) patients who developed treatment-related complications could be treated conservatively. Overall, 23 (5.5%) patients had incomplete resection without independent clinicopathological risk factors. CONCLUSION ESMR-L, ESD, and EMR-C were equally effective and safe for colorectal NETs with a diameter <10 mm.

Abstract
INTRODUCTION The efficacy of texture and color enhancement imaging (TXI) in the novel light-emitting diode endoscopic system for polyp detection has not been examined. We aimed to evaluate the noninferiority of the additional 30-second (Add-30-s) observation of the right-sided colon (cecum/ascending colon) with TXI compared with narrow band imaging (NBI) for detecting missed polyps. METHODS We enrolled 381 patients ≥40 years old who underwent colonoscopy from September 2021 to June 2022 in 3 institutions and randomly assigned them to either the TXI or NBI groups. The right-sided colon was first observed with white light imaging in both groups. Second, after reinsertion from hepatic flexure to the cecum, the right-sided colon was observed with Add-30-s observation of either TXI or NBI. The primary endpoint was to examine the noninferiority of TXI to NBI using the mean number of adenomas and sessile serrated lesions per patient. The secondary ones were to examine adenoma detection rate, adenoma and sessile serrated lesions detection rates, and polyp detection rates in both groups. RESULTS The TXI and NBI groups consisted of 177 and 181 patients, respectively, and the noninferiorities of the mean number of adenomas and sessile serrated lesions per patients in the second observation were significant (TXI 0.29 [51/177] vs NBI 0.30 [54/181], P < 0.01). The change in adenoma detection rate, adenoma and sessile serrated lesions detection rate, and polyp detection rate for the right-sided colon between the TXI and NBI groups were not different (10.2%/10.5% [ P = 0.81], 13.0%/12.7% [ P = 0.71], and 15.3%/13.8% [ P = 0.71]), respectively. DISCUSSION Regarding Add-30-s observation of the right-sided colon, TXI was noninferior to NBI.

Abstract
BACKGROUND AND AIM We investigated whether oral-dental conditions may be associated with the prevalence of irritable bowel syndrome (IBS) in a cross-sectional study in Japan. METHODS Information on lifestyle and abdominal symptoms was collected, and oral-dental examinations were performed from 2013 to 2017. To investigate the association between oral-dental conditions and IBS, this study used logistic regression analyses adjusted for relevant confounding factors, such as age, sex, BMI, stress, and eating between meals. RESULTS The prevalence of IBS was 484 (13.4%) among 3626 participants. The mean maximum occlusal force in the IBS group was significantly lower than that in the non-IBS group (0.306 ± 0.192 kN vs. 0.329 ± 0.205 kN, P = 0.014). The maximum occlusal force of the constipation-type IBS was significantly lower than that of other types of IBS without constipation type (0.269 ± 0.164 kN vs. 0.317 ± 0.198 kN, P = 0.010). Compared with those who had high values of maximum occlusal force (≧0.265 kN), those with a low value of maximum occlusal force (<0.265 kN) had a significantly greater risk for IBS (OR, 1.426; 95% CI, 1.135-1.792; P = 0.002), by multivariate analyses, across different categories of oral-dental condition in women, not in men. Women who had lowest third occlusal force (<0.206 kN) had approximately 35% significantly greater odds of having IBS compared with those who had highest third occlusal force (≧0.386 kN). CONCLUSIONS Results suggest that a reduction in the maximum occlusal force increases the risk of IBS in Japanese women.

Abstract
Background Additional ablation strategies after pulmonary vein isolation (PVI) for patients with nonparoxysmal atrial fibrillation (non-PAF) lasting ≥2 years have not been fully effective. This is presumably because of insufficient identification of non-PAF maintenance mechanisms. In this study, we employed a novel online and real-time phase mapping system, ExTRa Mapping, to identify and modulate rotors as one of the non-PAF maintenance mechanisms in patients with non-PAF sustained after PVI. We investigated the relationship between outcomes of ExTRa Mapping-guided rotor ablation (ExTRa-ABL) and non-PAF duration prior to this procedure. Methods This study consisted of 73 non-PAF patients (63 ± 8 years, non-PAF duration 31 ± 37 months) who underwent the first ExTRa-ABL in patients with non-PAF sustained after completion of PVI. Results Freedom from non-PAF/atrial tachycardia (AT) recurrence at 12 months after ExTRa-ABL was achieved in 50 (69%) of patients. The non-PAF duration prior to ExTRa-ABL was significantly longer in patients with non-PAF/AT recurrence after ExTRa-ABL compared with those without (56 ± 50 vs. 19 ± 22 months, p = .001). In patients with non-PAF duration of ≤60 months prior to ExTRa-ABL, compared with >60 months, non-PAF/AT-free rate was significantly higher (68.9% vs. 23.1%, p < .001), during the follow-up of 36 ± 18 months. Conclusions A non-PAF duration of ≤60 months prior to ExTRa-ABL was associated with a better outcome. The effect of ExTRa-ABL was considered to be limited in patients with >60 months of non-PAF duration.

Abstract
Abstract
Background
Cardiac calmodulinopathy is a life-threatening arrhythmia syndrome which presents several phenotypes of inherited primary arrhythmia syndrome (IPAS), and caused by mutations in calmodulin-encoded genes (CALM1–3). We aimed clarify the frequency and their clinical characteristics of calmodulinopathy in our IPAS cohort.
Methods
By using next generation sequencing, we screened arrhythmia related genes including calmodulin-encoding genes in 322 unrelated symptomatic children (0–12 years) who were suspected as IPAS; they included 40 cases with lethal arrhythmic attacks (LAE) under 6-year-old. After gene screening, we investigated their physiological and clinical characteristics about mutation carriers.
Results
Among 322 children, we identified 6 mutations of calmodulin-encoded genes in 9 probands (2.8%); one CALM1 in 2 probands (N98S), and 5 CALM2 in 7 probands (E46K, D96V, D96G, N98S, E141K). Their clinical diagnoses were long QT syndrome (LQTS, n=4), catecholaminergic polymorphic ventricular tachycardia (CPVT, n=3) and both (n=2). Their age of diagnosis ranges at 0–9 with the median of 5 years. There were three major clinical phenotypes; 1) CALM2-D96V, and E141K: two infants with advanced atrio-ventricular block, significant QTc prolongation, severe heart failure from their fetal period – both of them deceased within 1.5-year-old. Their clinical phenotypes resembled classical Timothy syndrome caused by CACNA1C mutations. 2) CALM1-N98S (n=2), CALM2-N98S (n=2), and CALM2-D96G: four preschoolers with LAEs and one syncope: all of them were 3–5 years old. In addition, a T wave morphology of CALM2-D96G carrier was very similar to LQT1. 3) CALM2-E46K (n=2): two were first diagnosed with neurological and developmental disorders, and showed phenotype of CPVT: their cardiac phenotypes were milder compared with that of 1) or 2). Overall, these phenotypes seemed to be mutation specific (indicated in figure). Their cardiac features were severer, and the onset of LAEs was earlier compared with other genotypes of LQTS/CPVT. As the treatment, β-blocker was effective for control of LAEs.
Conclusion
Cardiac calmodulinopathy presented serious and potentially lethal phenotypes in fetus or infancy. To prevent cardiac death in them, we must correctly diagnose and start the treatment as earlier as possible.

Abstract
BACKGROUND This is the first report from a multicenter prospective cohort study of colorectal neuroendocrine tumor (NET), the C-NET STUDY, conducted to assess the long-term outcomes of the enrolled patients. This report aimed to elucidate the clinicopathological features of the enrolled patients and lesions. METHODS Colorectal NET patients aged 20-74 years were consecutively enrolled and followed up at 50 institutions. The baseline characteristics and clinicopathological findings at enrollment and treatment were assessed. RESULTS A total of 495 patients with 500 colorectal NETs were included. The median patient age was 54 years, and 85.3% were asymptomatic. The most frequent lesion location was the lower rectum (88.0%); 99.4% of the lesions were clinically diagnosed to be devoid of metastatic findings, and 95.4% were treated with endoscopic resection. Lesions < 10 mm comprised 87.0% of the total, 96.6% had not invaded the muscularis propria, and 92.6% were classified as WHO NET grade 1. Positive lymphovascular involvement was found in 29.2% of the lesions. Its prevalence was high even in small NETs with immunohistochemical/special staining for pathological assessment (26.4% and 40.9% in lesions sized < 5 mm and 5-9 mm, respectively). Among 70 patients who underwent radical surgery primarily or secondarily, 18 showed positive lymph node metastasis. CONCLUSIONS The characteristics of real-world colorectal NET patients and lesions are elucidated. The high positivity of lymphovascular involvement in small NETs highlights the necessity of assessing the clinical significance of positive lymphovascular involvement based on long-term outcomes, which will be examined in later stages of the C-NET STUDY.

Abstract
BACKGROUND & AIMS SERENE UC (Study of a Novel Approach to Induction and Maintenance Dosing With Adalimumab in Patients With Moderate to Severe Ulcerative Colitis) evaluated the efficacy of higher adalimumab induction and maintenance dose regimens in patients with ulcerative colitis. METHODS This phase 3, double-blind, randomized trial included induction and maintenance studies, with a main study (ex-Japan) and Japan substudy. Eligible patients (18-75 years, full Mayo score 6-12, centrally read endoscopy subscore 2-3) were randomized 3:2 to higher induction regimen (adalimumab 160 mg at weeks 0, 1, 2, and 3) or standard induction regimen (160 mg at week 0 and 80 mg at week 2); all received 40 mg at weeks 4 and 6. At week 8, all patients were rerandomized 2:2:1 (main study) to 40 mg every week (ew), 40 mg every other week (eow), or exploratory therapeutic drug monitoring; or 1:1 (Japan substudy) to 40 mg ew or 40 mg eow maintenance regimens. RESULTS In the main study, 13.3% vs 10.9% of patients receiving the higher induction regimen vs standard induction regimen achieved clinical remission (full Mayo score ≤2 with no subscore >1) at week 8 (induction primary end point; P = .265); among week-8 responders, 39.5% vs 29.0% receiving 40 mg ew vs 40 mg eow achieved clinical remission at week 52 (maintenance primary end point; P = .069). In the integrated (main + Japan) population, 41.1% vs 30.1% of week-8 responders receiving 40 mg ew vs 40 mg eow achieved clinical remission at week 52 (nominal P = .045). Safety profiles were comparable between dosing regimens. CONCLUSION Although primary end points were not met, a >10% absolute difference in clinical remission was demonstrated with higher adalimumab maintenance dosing. Higher dosing regimens were generally well tolerated and consistent with the known safety profile of adalimumab in ulcerative colitis. CLINICALTRIALS gov, Number: NCT002209456.

Abstract
We herein report a 14-year-old boy with repetitive nocturnal syncope related to medication-refractory long QT syndrome (LQTS). Although the use of an implantable cardioverter-defibrillator (ICD) was inevitable to prevent sudden cardiac death, he refused immediate implantation in order to play in a baseball competition six weeks away. Given his genetic diagnosis of type 2 LQTS, which is associated with cardiac events unrelated to exercise, we prescribed a wearable cardioverter defibrillator (WCD) to be donned at night, without limiting his exercise participation. An ICD was implanted after the competition. We successfully performed the preplanned treatment while maximizing the patient's quality-of-life with a WCD and genotype-specific risk stratification.

Abstract
An advanced small bowel mucinous adenocarcinoma with Peutz-Jeghers syndrome was resected, and we started capecitabine plus oxaliplatin (CapeOX) as adjuvant therapy. However, local recurrence was noted, and the tumor increased even after CapeOX plus bevacizumab and fluorouracil plus leucovorin plus irinotecan plus panitumumab (FOLFIRI plus panitumumab). Pembrolizumab was administered after confirming high-frequency microsatellite instability, and the tumor shrank markedly and remained shrunk for 20 months.

Abstract
A 59-year-old man was treated for early gastric cancer with endoscopic submucosal dissection (ESD) 10 years prior to the study. Two months after the first ESD, he was diagnosed with recurrence on the ESD scar and treated via ESD again. The horizontal margin could not be evaluated because of cauterization, and the patient was carefully observed. He was admitted to our hospital complaining of low backache and diagnosed with disseminated carcinomatosis of the bone marrow associated with gastric cancer after examination. Although he started chemotherapy, he died after 6 months. In this study, we report a rare case of disseminated carcinomatosis of the bone marrow associated with gastric cancer, which developed 10 years after ESD.

Abstract
Managing irritable bowel syndrome (IBS) has attracted international attention because single-agent therapy rarely relieves bothersome symptoms for all patients. The Japanese Society of Gastroenterology (JSGE) published the first edition of evidence-based clinical practice guidelines for IBS in 2015. Much more evidence has accumulated since then, and new pharmacological agents and non-pharmacological methods have been developed. Here, we report the second edition of the JSGE-IBS guidelines comprising 41 questions including 12 background questions on epidemiology, pathophysiology, and diagnostic criteria, 26 clinical questions on diagnosis and treatment, and 3 questions on future research. For each question, statements with or without recommendations and/or evidence level are given and updated diagnostic and therapeutic algorithms are provided based on new evidence. Algorithms for diagnosis are requisite for patients with chronic abdominal pain or associated symptoms and/or abnormal bowel movement. Colonoscopy is indicated for patients with one or more alarm symptoms/signs, risk factors, and/or abnormal routine examination results. The diagnosis is based on the Rome IV criteria. Step 1 therapy consists of diet therapy, behavioral modification, and gut-targeted pharmacotherapy for 4 weeks. For non-responders, management proceeds to step 2 therapy, which includes a combination of different mechanistic gut-targeted agents and/or psychopharmacological agents and basic psychotherapy for 4 weeks. Step 3 therapy is for non-responders to step 2 and comprises a combination of gut-targeted pharmacotherapy, psychopharmacological treatments, and/or specific psychotherapy. These updated JSGE-IBS guidelines present best practice strategies for IBS patients in Japan and we believe these core strategies can be useful for IBS diagnosis and treatment globally.

Abstract
A 53-year-old man who had been diagnosed with moderate ulcerative colitis and treated with mesalazine and glucocorticoid steroid was admitted due to fever of unknown origin and diarrhea. Intravenous feeding and treatment with cephem antibiotics were started, but the febrile reaction did not improve at all. Physical examination and various tests showed no specific symptoms, including headache or meningeal irritation. However, the blood culture test showed a positive result of Gram-positive bacilli. Thus, a lumbar puncture was performed and the patient was finally diagnosed with Listeria monocytogenes bacteremia and meningitis. Administration of intravenous meropenem and ampicillin led to the improvement of symptoms without any neurological sequelae. In addition, several cases with opportunistic infection of L. monocytogenes have been reported in recent years in cases of inflammatory bowel disease (IBD) during immunosuppressive therapy. Consequently, L. monocytogenes infection should be considered as one of differential diagnosis when patients present with IBD patient and are treated by biological or immunosuppressive agents with a fever of unknown origin.

Abstract
Background Nonalcoholic fatty liver disease is characterized by excessive hepatic fat accumulation. Some individuals frequently present elevated gamma-glutamyl transferase (GGT) levels without fatty liver ultrasound images and other abnormal liver enzymes levels. However, whether these individuals are at an elevated risk for developing fatty liver is unclear. We compared fatty liver change rates and risk factors between individuals with frequently elevated GGT levels and those with normal levels. Methods We designed a retrospective cohort study on the basis of complete medical checkup records. One group of individuals had presented normal serum GGT levels during the observation period (Normal-GGT group, n = 2713). Another group had had abnormal elevated serum GGT levels frequently (Abnormal-GGT group, n = 264). We determined the fatty liver change incident rates before and after propensity score matching. We explored confounding factors affecting fatty changes in each group using univariate and multivariate Cox models. Results The change incidence rates were 5.80/1000 and 10.02/1000 person-years in the Normal-GGT and Abnormal-GGT groups, respectively. After propensity score matching, the incidence rates were 3.08/1000 and 10.18/1000 person-years in the Normal-GGT and Abnormal-GGT groups, respectively (p = 0.026). The factors associated with fatty liver changes in the Normal-GGT group included body mass index (BMI), hemoglobin, alanine aminotransferase (ALT), albumin, triglyceride (TG), fasting blood sugar, and high-density lipoprotein levels. Those in the Abnormal-GGT group were platelet counts and TG. In our multivariable analysis, BMI, ALT, albumin, and TG levels were independent predictors of fatty changes in the Normal-GGT group, and high TG level was the only independent predictor in the Abnormal-GGT group. Conclusions The incidence rate of fatty liver change in the Abnormal-GGT group was higher than that in the Normal-GGT group. Consecutive elevated GGT levels increase the risk for fatty liver, and high TG levels in those individuals further independently increase the risk.

Abstract
Abstract
Introduction
It is reported that for patients with non-paroxysmal (persistent or long-standing persistent) atrial fibrillation (Non-PAF), extended ablation to atrial walls in addition to pulmonary vein isolation (PVI) did not improve the long-term outcome. On the other hand, modulation of Non-PAF drivers (or perpetuators) has been proposed as one of the alternative effective ablation strategies for Non-PAF.
Purpose
To clarify whether the rotor ablation under online real-time high-density phase mapping system is effective for PVI-refractory Non-PAF ablation.
Methods
Under such circumstances, our academic group had recently developed the online real-time high-density phase mapping system (ExTRa Mapping™) by industrial alliance. The phase map moving images were based on 41 intra-atrial bipolar signals recorded by a 20-pole spiral-shaped catheter (2.5 cm in diameter) and on in silicorapid prediction of spatio-temporal atrial excitations (artificial intelligence system). Then we applied the ExTRa Mapping to clinical practice in order to directly visualize rotors in patients with Non-PAF, and investigated the middle- to long-term outcome of the ExTRa Mapping-guided rotor ablation (ExTRa-ABL).
Results
Thirty-eight patients (63±8 y/o, 30 males) with Non-PAF demonstrating refractoriness to PVI were enrolled in this study. Ablation for cavo-tricuspid isthmus and/or superior vena cava isolation was additionally performed at physicians' discretion. After these procedures, the ExTRa-ABL was performed in order to modify Non-PAF substrates, causing rotor control. The modification of the rotors was evaluated by re-mapping with the use of the ExTRa Mapping at the end of each ablation session. Patients were followed at 1, 3, 6 months and every year after the procedure. All of them were followed for 21±8 months. During the follow-up period, Non-PAF was recurred in only 8 of 38 (21%). Furthermore, we found if PVI-refractory Non-PAF duration was shorter than 6 years, the non-recurrence rate remained ≥80% (see Figure), which was markedly better outcome comparing with previous reports with regard to Non-PAF ablation.
Figure 1
Conclusion
Comparing with conventional Non-PAF ablation strategies, our novel approach with the use of the online real-time high-density phase mapping system might improve medium- to long-term outcome of PVI-refractory Non-PAF treatment.

Abstract
BACKGROUND/AIMS This study investigated the effect of Helicobacter pylori eradication therapy on latent digestive symptoms in chronic atrophic gastritis. METHODS We enrolled 650 health checkup patients who underwent eradication therapy for chronic gastritis and completed a self-report questionnaire before and after the treatment between January 2014 and December 2016 at the Japanese Red Cross Society Kyoto Daiichi Hospital. RESULTS H. pylori eradication therapy for chronic atrophic gastritis improved latent digestive symptoms, including both the acid reflux and dyspepsia components in the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) scores. The effect was sustained until 1 year after the treatment. Higher FSSG scores (≥8 points) before H. pylori eradication therapy and age <70 years were significantly associated with the improvement of digestive symptoms after H. pylori eradication therapy. CONCLUSION H. pylori eradication therapy may improve patients' quality of life through the resolution of latent abdominal symptoms.

Abstract
OBJECTIVE The major causes of unpleasant human body odour are aldehydes produced by axillary-resident bacteria. There are many methods of body odour prevention; however, they all carry risks of destroying indigenous dermal bacteria that are necessary for the maintenance of the normal physical function of the skin. Furthermore, some methods cannot directly reduce the concentrations of substances that cause body odour. Therefore, a novel method of reducing body odour more safely and effectively is required. We focused on acetic acid bacterial enzymes, which can convert aldehydes into carboxylic acids, and investigated their effect on aldehydes and body odour. METHODS Subjects with strong body odour were recruited using screening questionnaires. Acetic acid bacterial extract including enzymes was applied to subjects' skin, and their effects were evaluated by trained panellists and by quantitative aldehyde analysis using thermal detector gas chromatography/mass spectrometry. RESULTS Acetic acid bacterial extract including enzymes decreased the ratio of dilution to threshold and the concentration of body odour-producing aldehydes dropped by up to 98.7%. CONCLUSION These results indicate that simply applying acetic acid bacterial enzymes on the skin can reduce the concentration of aldehydes that cause unpleasant body odour by directly converting them into carboxylic acids. Therefore, acetic acid bacterial enzymes can potentially be developed into new products that do not destroy indigenous bacteria and yet can effectively reduce unpleasant body odour.

Abstract
Background Effects of nonparoxysmal atrial fibrillation (non-PAF) ablation targeting complex fractionated atrial electrogram (CFAE) areas and/or low voltage areas (LVAs) are still controversial. Methods and Results A recently developed online real-time phase mapping system (ExTRa Mapping) was used to conduct LVA mapping and simultaneous ExTRa and CFAE mapping in 28 non-PAF patients after pulmonary vein isolation (PVI). Nonpassively activated areas, in the form of meandering rotors and/or multiple wavelets assumed to contain non-PAF drivers, partly overlapped with CFAE/LVAs but not always coincided with them. Conclusion Real-time rotor imaging, rather than conventional indirect indicators only, might be very useful for detecting non-PAF drivers.

Abstract
We report a rare case of bile duct stone formation around an ingested fish bone as a nidus after pancreatoduodenectomy. A 78-year-old woman was admitted to our department for fever and epigastric pain. Abdominal computed tomography revealed an elongated bile duct stone containing a linearly shaped foreign body of bone density. Enteroscopic lithotomy was performed using single balloon enteroscopy to safely remove the stone and foreign body from the bile duct. The foreign body was determined to be a fish bone by pathological examination and component analysis.

Abstract
A 40-year-old man admitted to our hospital with diarrhea underwent abdominal computed tomography (CT) which showed multiple masses in the liver and pancreatic tail. Although there were no abnormal accumulations with fluorodeoxyglucose ((18)F) positron emission tomography (FDG-PET), (68)Ga-DOTATOC-PET/CT detected obvious abnormal accumulations for the both lobes of liver and pancreatic tail tumors. The serum gastrin was markedly high, and liver tumor biopsy demonstrated the presence of malignant cells with round nuclei that were positive for gastrin and somatostatin receptor. The patient was diagnosed with pancreatic tail gastrinoma with multiple liver metastases and treated with octreotide, everolimus, and a proton pump inhibitor which functionally controlled tumor growth. This case demonstrates (68)Ga-DOTATOC-PET/CT as a useful modality for the localization, qualitative diagnosis, and treatment of gastrinoma.

Abstract
Here, we report our experience with a case of severe biliary bleeding due to a hepatic arterial pseudoaneurysm that had developed 1 year after endoscopic biliary plastic stent insertion. The patient, a 78-year-old woman, presented with hematemesis and obstructive jaundice. Ruptured hepatic arterial pseudoaneurysm was diagnosed, which was suspected to have been caused by long-term placement of an endoscopic retrograde biliary drainage (ERBD) stent. This episode of biliary bleeding was successfully treated by transarterial embolization (TAE). Pseudoaneurysm leading to hemobilia is a rare but potentially fatal complication in patients with long-term placement of ERBD. TAE is a minimally invasive procedure that offers effective treatment for biliary bleeding.

Abstract
Background and Aims Patients with ulcerative colitis (UC) are at risk for developing colorectal cancer (CRC), despite the development of new therapeutic agents. Stratification of the individual UC-patient's risk would be helpful to validate the risk factors for CRC. The aim of this study was to evaluate the risk factors for the development of CRC in a large cohort of patients with UC. Methods Data were obtained from 12 hospitals in the Kyoto-Shiga region during 2003–2013. We performed a retrospective cohort study of 2137 patients with UC. Results In total, 60 lesions of CRC were detected in 43 (2.0%) of 2137 patients. 30 of the 43 patients were male. The median age was 53 years. The median duration of disease was 13 years, and 67.4% of these patients had a disease duration >10 years. Of the 43 patients, 34 (79.1%) had extensive colitis. Primary sclerosing cholangitis was detected in 2 patients (4.7%). The median corticosteroids (CS) dose was 6.4 g, and 4 patients were treated with a total of more than 10 g of CS. 18 of these patients underwent more than 1 year CS treatment. Of all 60 CRC lesions, 43 (71.7%) were located in the distal colon and 35 (58.3%) were of the superficial type. Moreover, the stage of CRC was stage 0 or I in 55.8% of the 43 patients with CRC. Multivariate analysis suggested that extensive colitis could be a risk factor for the development of advanced CRC in patients with UC. Conclusions Our findings indicated that male, extensive colitis, long-term duration of UC and family history of CRC, but not concomitant primary sclerosing cholangitis, are important factors for predicting CRC in Japanese patients with UC. Moreover, long-standing extensive colitis might contribute to the progression of CRC. Further studies are required to establish CRC surveillance in Japanese patients with UC.

Abstract
AIM To investigate usefulness of triple therapy with vonoprazan, a potassium ion-competitive acid blocker and antibiotics, for Helicobacter pylori (H. pylori) eradication.
METHODS The H. pylori eradication rate was examined in 2507 patients (2055 undergoing primary eradication and 452 undergoing secondary eradication, excluding patients with subtotal gastrectomy) at the Japanese Red Cross Kyoto Daiichi Hospital from March 2013 to September 2015. For patients treated from March 2013 to February 2015, a proton pump inhibitor (PPI) was used to reduce acid secretion, while vonoprazan was used after March 2015. The success rates of the 2 regimens (PPI + amoxicillin + clarithromycin/metronidazole, or vonoprazan + amoxicillin + clarithromycin/metronidazole) were compared.
RESULTS The success rate of primary H. pylori eradication was significantly higher in the vonoprazan group. When stratified by the underlying disease, a significant increase of the H. pylori eradication rate was observed in patients with chronic gastritis. A significantly lower H. pylori eradication rate was observed in younger patients compared to older patients in the PPI group, but there was no difference according to age in the vonoprazan group. On the other hand, the success rate of secondary eradication was similar at approximately 90% in both groups.
CONCLUSION Vonoprazan is very useful for primary eradication of H. pylori, and may become a first-line acid secretion inhibitor instead of PPIs.

Abstract
SGEF and Ephexin4 are members of the Ephexin subfamily of RhoGEFs that specifically activate the small GTPase RhoG. It is reported that Ephexin1 and Ephexin5, two well-characterized Ephexin subfamily RhoGEFs, are tyrosine-phosphorylated by Src, and that their phosphorylation affect their activities and functions. In this study, we show that SGEF, but not Ephexin4, is tyrosine-phosphorylated by Src. Tyrosine phosphorylation of SGEF suppresses its interaction with RhoG, the elevation of RhoG activity, and SGEF-mediated promotion of cell migration. We identified tyrosine 530 (Y530), which is located within the Dbl homology domain, as a major phosphorylation site of SGEF by Src, and Y530F mutation blocked the inhibitory effect of Src on SGEF. Taken together, these results suggest that the activity of SGEF is negatively regulated by tyrosine phosphorylation of the DH domain.

Abstract
The case of a 34-year-old man with relapsing Ph+ acute lymphoblastic leukemia (ALL), which occurred five months after allogeneic bone marrow transplantation, is described. He was originally treated with aggressive chemotherapy, which put him in hematological remission, and he subsequently received donor leukocyte infusion (DLI) form the original donor. To assess the efficacy of this adoptive immunotherapy, we monitored minor-BCR/ABL (m-BCR/ABL) mRNA levels using the recently established real-time quantitative RT-PCR (RQ-PCR) assay. The results were compared with those obtained using conventional qualitative RT-PCR assays run in parallel. RQ-PCR, but not RT-PCR-based, minimum residual disease (MRD) detection showed a good correlation with the rapid changes documented during the post-DLI clinical course. Currently, six months after DLI, the patient continues to be in remission, which is consistent with the undetectable levels of m-BCR/ABL mRNA in the leukemic clone using RQ-PCR found in this study. Thus, monitoring of m-bcr/abl transcripts using RQ-PCR provides more useful information on a clinical assessment of MRD.

Abstract
A 17-year-old boy developed prominent mediastinal and subcutaneous emphysema while receiving treatment with 5-aminosalicylic acid (5-ASA) and oral corticosteroids for severe ulcerative colitis. We ruled out infection and initiated oral administration of tacrolimus, after which both the underlying disease and mediastinal and subcutaneous emphysema improved. However, he continued to experience repeated bouts of ulcerative colitis, so we ultimately opted for surgical intervention. Although mediastinal and subcutaneous emphysema is rare, it is one of the known extra-intestinal complications and can be particularly concerning. In this patient, mediastinal and subcutaneous emphysema might have been caused by the vulnerability of pulmonary alveolar walls to steroid medication and the increase of pulmonary alveolar pressure with abdominal pain and breath holding. Here, we report a case of inflammatory bowel disease with mediastinal and subcutaneous emphysema, along with a review of the literature.

Abstract
BACKGROUND Patients with ulcerative colitis (UC) have elevated/activated myeloid lineage leucocytes and may respond favorably to adsorptive granulocyte/monocyte apheresis (GMA). However, there are patients who respond well to GMA, and patients who do not benefit. Therefore, predictive factors of GMA efficacy need to be defined. METHODS In a prospective multicenter setting, 200 UC patients at 32 institutes received one GMA session per week over 10 weeks. Patients who achieved remission were followed for 12 months. The Clinical Activity Index (CAI) ≤3 meant remission, and response meant CAI decreased by ≥3. Quality of life was evaluated by the Inflammatory Bowel Disease Questionnaire (IBDQ). RESULTS After final GMA, remission, response and no response rates were 67.0%, 15.0% and 18%, respectively. The remission group had a significant decrease in myeloid leucocytes and platelets. Corticosteroid dose decreased (P < 0.001); 49 of 97 patients on corticosteroids became steroid-free. Baseline CAI was lower in the remission group versus non-remission (P < 0.01), whereas IBDQ was higher in the remission group versus non-remission (P < 0.05). After 12 months, 52 of 134 patients had maintained remission. Disease duration was longer in the relapsed group versus maintained remission group (P = 0.041). Male gender, first UC episode and corticosteroid responder were significant factors for maintaining remission, whereas corticosteroid dependent UC was associating with relapse. DISCUSSION Selective myeloid leucocyte depletion was effective for remission induction and improving patients' quality of life. Baseline demographics such as disease activity level, duration and corticosteroid dependency appear to predict response to GMA. Additionally, patients with a first UC episode who were drug naive responded well to GMA and achieved a favorable long-term disease course by avoiding pharmacologics from an early stage of their inflammatory bowel disease. These findings should help to end unnecessary use of medical resources by targeting GMA to patients who may respond well.

Abstract
Floral scents are among the key signals used by pollinators to navigate to specific flowers. Thus, evolutionary changes in scents should have strong impacts on plant diversification, although scent-mediated plant speciation through pollinator shifts has rarely been demonstrated, despite being likely. To examine whether and how scent-mediated plant speciation may have occurred, we investigated the Asimitellaria plant lineage using multidisciplinary approaches including pollinator observations, chemical analyses of the floral scents, electroantennographic analyses and behavioural bioassays with the pollinators. We also performed phylogenetically independent contrast analyses of the pollinator/floral scent associations. First, we confirmed that the pairs of the sympatric, cross-fertile Asimitellaria species in three study sites consistently attract different pollinators, namely long-tongued and short-tongued fungus gnats. We also found that a stereoisomeric set of floral volatiles, the lilac aldehydes, could be responsible for the pollinator specificity. This is because the compounds consistently elicited responses in the antennae of the long-tongued fungus gnats and had contrasting effects on the two pollinators, that is triggering the nectaring behaviour of long-tongued fungus gnats while repelling short-tongued fungus gnats in a laboratory experiment. Moreover, we discovered that volatile composition repeatedly switched in Asimitellaria between species adapted to long-tongued and short-tongued fungus gnats. Collectively, our results support the idea that recurrent scent-mediated speciation has taken place in the Asimitellaria–fungus gnat system.

Abstract
BACKGROUND AND OBJECTIVES This study compares the frequency of adverse transfusion reactions (ATRs) after first transfusions with the frequency of ATRs for subsequent (non-first) transfusions. MATERIALS AND METHODS Five hospitals agreed to systematically collect and share 2 years of data. This was a retrospective observational analysis of data including the number of transfusion episodes and ATRs for red blood cells (RBCs), fresh frozen plasma (FFP) and platelet concentrates (PCs) given to first-time transfusion recipients and to those previously transfused. RESULTS First transfusion ATRs to RBCs, FFP and PCs were 1.08%, 2.84% and 3.34%, respectively. These are higher than ATR incidences to RBCs (0.69%), FFP (1.91%) and PCs (2.75%) on subsequent transfusions. Specifically, first transfusion incidences of febrile non-haemolytic transfusion reactions (FNHTRs) to RBCs (0.43%) and allergic reactions to FFP (2.51%) were higher than on subsequent transfusions (RBCs: 0.23%, FFP: 1.65%). CONCLUSION There are risks of ATRs on the first transfusion as well as transfusions of patients with transfusion history.

Abstract
AIM This is a multicenter phase II study to assess the efficacy and toxicity of FOLFIRI treatment agents in full and the influence of UGT1A1*28 polymorphism in Japanese patients with advanced/metastatic colorectal cancer (mCRC). PATIENTS AND METHODS Fifty patients with mCRC participated in this study. Treatment consisted of FOLFIRI (irinotecan; 150 mg/m(2)) as second-line chemotherapy; 34 patients consented to the evaluation of UGT1A1 genotype. RESULTS The overall response rate was 12% for all 50 evaluable patients; 31 patients (62.0%) had stable disease, and only in 12 (24.0%) did disease progress. The median progression-free survival was 5.8 months. The tolerance treatment was acceptable, with only 15 out of 50 patients (30%) experiencing grade 3/4 neutropenia, and grade 4 thrombocytopenia was observed in only one case. Grade 3 non-hematological adverse reactions included stomatitis in three, diarrhea in one, and a clinically insignificant increase in serum alkaline phosphatases in one patient, respectively. There was no definite relation between the UGT1A1*28 polymorphism and toxicity. CONCLUSION Standard FOLFIRI regimen can be administered to Japanese patients. The results showed good tolerability and efficacy for second-line FOLFIRI, provided that evaluation of UGT1A1 polymorphism is properly implemented before the start of the chemotherapy.

Abstract
UNLABELLED Retrospective studies have suggested that UDP-glucuronosyltransferase (UGT)1A1, UGT1A7, and UGT1A9 predict severe toxicity and efficacy of irinotecan-containing regimens. We prospectively evaluated the impact of UGT1A genotypes and haplotypes on severe toxicity and efficacy in patients treated with fluorouracil, leucovorin, and irinotecan combination chemotherapy (FOLFIRI) for metastatic colorectal cancer (mCRC) from the two prospective multicenter phase II studies in Japan. The FLIGHT1 study was a first-line FOLFIRI trial, and FLIGHT2 was a FOLFOX-refractory, second-line FOLFIRI trial. A total of 73 patients agreed to additional analysis, and were genotyped for UGT1A polymorphisms, UGT1A1*28 (TA6>TA7), UGT1A1*6 (211G>A), UGT1A1*27 (686C>A), UGT1A1*60 (-3279T>G), UGT1A1*93 (-3156G>A), UGT1A7 (-57T>G), UGT1A7*3 (387T>G, 622T>C), and UGT1A9*22 (T9>T10). Of 73 patients, 34 developed G3/4 severe hematological toxicities. The toxicities were significantly more frequent in patients with UGT1A1*6 (211A), UGT1A7 (387G), and UGT1A9*22 reference alleles (T9). Haplotype I, which consists of all favorable alleles, was associated with a significant reduction in hematologic toxicity (P = 0.031). In contrast, haplotype II, which contains four high-risk alleles, showed significantly higher hematologic toxicity than the other haplotypes (P = 0.010). Six out of seven patients who were homozygous for UGT1A1*28 or *6 experienced severe hematological toxicity despite the fact that their response rate was not impaired (42.9%). We concluded that UGT1A polymorphisms, especially UGT1A1*6, are important for the prediction of severe toxicity of FOLFIRI in northeast Asian populations. In this regard, haplotype analyses should substantially impact the prediction of severe hematological toxicities of FOLFIRI. ( CLINICAL TRIAL REGISTRATION UMIN000002388 and UMIN000002476).

Abstract
Objective In Japan, there had been no prospective clinical studies conducted in terms of modified FOLFOX6 + bevacizumab therapy. We performed a post-marketing Phase II multicenter clinical study to examine the efficacy and safety of this regimen as first-line therapy for Japanese patients with advanced/recurrent colorectal cancer. Methods Bevacizumab (5 mg/kg) was administered intravenously, and then oxaliplatin (85 mg/m2) and levofolinate calcium (200 mg/m2) were infused intravenously over 2 h. Subsequently, a bolus dose of 5-fluorouracil (400 mg/m2) was injected, followed by infusion of 5-fluorouracil (2400 mg/m2) for 46 h. This regimen was repeated every 2 weeks until 24 cycles unless there was disease progression, unacceptable toxicity or patient refusal. The primary end point was the response rate. Results Among the 70 patients enrolled, two patients withdrew the study before treatment, and 68 patients were eligible for analysis of efficacy and safety. The response rate was 51.5% (95% confidence interval: 39.0–63.8%). The median progression-free survival and median overall survival time were 12.6 months (95% confidence interval: 10.4–14.5 months) and 28.5 months [95% confidence interval: 23.1 months–(not applicable)], respectively. There were no treatment-related deaths observed. The most common Grade 3 and 4 adverse events included neutropenia in 35.3% of the patients, peripheral neuropathy in 16.2% and hypertension in 16.2%. All adverse events were manageable and tolerable. The exploratory analysis of polymorphisms of three genes, ERCC1, XPD and GSTP1, did not show any trends in terms of correlation with the efficacy or safety of modified FOLFOX6 + bevacizumab therapy. Conclusions Modified FOLFOX6 + bevacizumab therapy was manageable and tolerable in Japanese patients, achieving a high response rate.

Abstract
OBJECTIVE This study aimed to assess the efficacy and tolerability of leukocytapheresis (LCAP) and to investigate predictive factors for mucosal healing and a sustained clinical response in steroid-free and steroid-refractory patients with ulcerative colitis (UC). MATERIAL AND METHODS Thirty-one steroid-free or steroid-refractory patients with active UC were enrolled. Five or ten consecutive sessions of LCAP were performed in each patient. The efficacy and tolerability was then evaluated at weeks 3 and 6. Endoscopic examination was performed at week 6 to evaluate the mucosal healing, and the sustained cumulative response rate was evaluated at 12 months. RESULTS At week 6, the mean Mayo clinical activity score had decreased significantly from 8.0 to 4.6 in the steroid-free patients and from 8.3 to 3.9 in the steroid-refractory patients. Rachmilewitz's endoscopic index had also decreased significantly from 9.1 to 6.1 in the steroid-free patients and from 10.0 to 5.7 in the steroid-refractory patients. Forty-seven percent of the steroid-free patients and 33% of the steroid-refractory patients achieved mucosal healing. The peripheral platelet counts had decreased significantly at weeks 3 and 6 in the mucosal healing group, compared with the non-mucosal healing group. The patients with a more than 15% platelet reduction had a significantly higher cumulative response rate, compared with the patients without a platelet reduction (p = 0.015). CONCLUSIONS LCAP is beneficial for the induction of mucosal healing in steroid-free and steroid-refractory patients with UC. The degree of platelet reduction during LCAP might be a predictive marker for mucosal healing and a sustained clinical response.

Abstract
Poorly differentiated neuroendocrine cell carcinomas of the gallbladder are rare and patients with such tumors have a poor prognosis. We describe a 64-year-old male with a large cell neuroendocrine carcinoma of the gallbladder and multiple lymph node metastases. Diagnostic excisional biopsy of the left axillary lymph nodes revealed atypical cells with predominantly large-sized round-to-oval nuclei, proliferating in a solid and focal nesting pattern. The tumor cells were positive for synaptophysin and chromogranin A, and strongly positive for Ki-67, leading to a diagnosis of poorly differentiated neuroendocrine cell carcinoma of the gallbladder, of large cell type. Using (18)F-fluorodeoxy glucose-positron emission tomography/computed tomography to determine the origin of these tumors, we observed the accumulation of (18)F-fluorodeoxy glucose in multiple large lymph nodes, a small part of the liver and the fundus of the gallbladder. Computed tomography-guided aspiration of the gallbladder showed the same pleomorphic tumor cells as the lymph nodes. The patient was diagnosed with a large cell neuroendocrine carcinoma of the gallbladder, only ∼25 mm in diameter. Combination chemotherapy with cisplatin and docetaxel, the regimen used for non-small cell lung carcinomas, and probably large cell lung carcinomas, resulted in the disappearance of the lymph node metastases and a marked improvement in the performance status for ∼22 months. The poor prognosis of patients with these aggressive tumors may be improved by the use of minimally invasive diagnostic procedures and combined systemic chemotherapy as soon as possible.

Abstract
Staphylococcal food poisoning is a gastrointestinal illness. It is caused by eating foods contaminated with enterotoxins produced by Staphylococcus aureus. The enterotoxins are fast acting, sometimes causing illness within one to six hours. Patients typically experience nausea, vomiting, stomach cramps, and diarrhea. Diagnosis of staphylococcal food poisoning is generally based only on the symptoms of patients. The treatments for these patients are rest and plenty of fluids. Antibiotics are not useful in treating this illness. On the other hand, methicillin resistant Staphylococcus aureus (MRSA) enteritis and colitis caused by microbial substitution with administration of antibiotics is aggressive and sick with severe diarrhea. The treatment of those patients are as follows; antibiotics now in use are stopped and oral administration of vancomycin is started as soon as possible.

Abstract
In this article, a series of fluorinated polyimides rubbed at different pressures was prepared, and the plasma protein adsorption on the rubbed polyimide films was evaluated using a micro-bicinchoninic acid protein assay. Interestingly, the amount of plasma protein adsorbed on the polyimide surface strongly depended on the rubbing pressure. The amounts of BSA and Fbg adsorbed on the rubbed polyimide film significantly decreased with an increase in the rubbing pressure. In contrast, the amounts of IgG adsorbed on the rubbed film dramatically increased with an increase in the rubbing pressure. In particular, it is interesting to note that a specific adsorption surface for IgG is formed by the rubbing process. We proposed that the nano-ordered hydrophilic and hydrophobic patternings formed on the top and bottom surfaces on the rubbed fluorinated polyimide film might have a significant influence on the plasma protein adsorption.

Abstract
During ambulatory monitoring, it is sometimes required to record an electroencephalogram (EEG) and an electrocardiogram (ECG) simultaneously. It would be ideal if both EEG and ECG could be obtained with one measurement. Here, we introduce an algorithm that combines the wavelet shrinkage and variable cosine window operation to separate the EEG and ECG components from an EEG signal recorded with a noncephalic reference (NCR). Evaluation using simulated data and actual measured data showed that accurate frequency analysis of EEG and an R-R detection-based heart rate analysis were feasible with our proposed algorithm, which improved the signal-averaging based algorithm so that ECG components containing ectopic beats can be applied.

Abstract
BACKGROUND Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder comprising abdominal pain, abdominal discomfort, and disordered defecation. The prevalence of IBS is 10-15% in the general population. This study investigated the prevalence of IBS and the relationship between IBS and stress, lifestyle, and dietary habits among nursing and medical school students. METHODS A blank self-administrated questionnaire was used to survey 2,639 students studying nursing or medicine. This questionnaire asked about IBS symptoms, lifestyle, dietary intake, life events, anxiety, and depression. The questionnaires were collected from 2,365 students (89.6%) and the responses of 1,768 students (74.8%) were analyzed. RESULTS The prevalence of IBS was 35.5% as a whole, 25.2% in males and 41.5% in females. Significantly higher stress scores (anxiety and depression) and life events were found in the IBS group than in the non-IBS group. Sleep disorders and the time spent sitting were also higher in males with IBS. In the IBS group, females ate less fish, fruit, milk, and green-yellow vegetables, and more processed food products than the non-IBS group (p = 0.001, p = 0.002, p = 0.032, p = 0.037, p < 0.001). The rates of missed meals and irregular mealtimes were significantly higher in females in the IBS group (p = 0.001, p = 0.013). CONCLUSIONS The prevalence of IBS was higher among nursing and medical students, and further interventional studies are needed to improve IBS symptoms.
