Abstract
Adult-onset intussusception, particularly associated with colonoscopy, is extremely rare. A 78-year-old man, referred to our hospital for colonic endoscopic mucosal resection (EMR), experienced subsequent dull abdominal pain, as well as elevated peripheral blood leukocytosis and C-reactive protein levels. Abdominal computed tomography (CT) revealed a colocolonic intussusception at the hepatic flexure. Emergency colonoscopy revealed ball-like swollen mucosa distal to the EMR site of the ascending colon. The mucosa was intact without necrosis. The endoscopic approach was able to temporarily release the intussusception. A transanal drainage tube was inserted through the endoscope to prevent relapse. Both CT and colonoscopy showed release of the intussusception. Our case underscores the importance of considering colocolonic intussusception in post-colonoscopy abdominal pain, advocating for endoscopic management after excluding mucosal necrosis.

Abstract
Although the use of immune checkpoint inhibitors (ICIs)-targeted agents for unresectable hepatocellular carcinoma (HCC) is promising, individual response variability exists. Therefore, we developed an artificial intelligence (AI)-based model to predict treatment efficacy using pre-ICIs contrast-enhanced computed tomography (CT) imaging characteristics. We evaluated the efficacy of atezolizumab and bevacizumab in 43 patients at the Nagasaki University Hospital from 2020 to 2022 using the modified Response Evaluation Criteria in Solid Tumors. A total of 197 Progressive Disease (PD), 271 Partial Response (PR), and 342 Stable Disease (SD) contrast CT images of HCC were used for training. We used ResNet-18 as the Convolutional Neural Network (CNN) model and YOLOv5, YOLOv7, YOLOv8 as the You Only Look Once (YOLO) model with precision-recall curves and class activation maps (CAMs) for diagnostic performance evaluation and model interpretation, respectively. The 3D t-distributed Stochastic Neighbor Embedding was used for image feature analysis. The YOLOv7 model demonstrated Precision 53.7%, Recall 100%, F1 score 69.8%, mAP@0.5 99.5% for PD, providing accurate and clinically versatile predictions by identifying decisive points. The ResNet-18 model had Precision 100% and Recall 100% for PD. However, the CAMs sites did not align with the tumors, suggesting the CNN model is not predicting that a given CT slice is PD, PR, or SD, but that it accurately predicts Individual Patient's CT slices. Preparing substantial training data for tumor drug effect prediction models is challenging compared to general tumor diagnosis models; hence, large-scale validation using an efficient YOLO model is warranted.

Abstract
(1) Background: Delayed perforation after gastric endoscopic submucosal dissection (ESD) for early gastric cancer is a relatively uncommon and serious complication that sometimes requires emergency surgery. This study aimed to determine the clinicopathological features, risk factors, and appropriate management strategies for delayed perforation. (2) Methods: This study included 735 patients with 791 lesions who underwent ESD for early gastric cancer at a single institution between July 2009 and June 2019. We retrospectively compared the clinical features of patients with and without delayed perforations. (3) Results: The incidence of delayed perforations was 0.91%. The identified risk factors included a postoperative stomach condition and histopathological ulceration. A comparison between delayed and intraoperative perforations revealed a postoperative stomach condition as a characteristic risk factor for delayed perforation. Patients with delayed perforation who avoided emergency surgery tended to exhibit an earlier onset of symptoms such as abdominal pain and fever. No peritoneal seeding following delayed perforation was observed for any patient. (4) Conclusions: A postoperative stomach condition and histopathological ulceration were risk factors for delayed perforation. Delayed perforation is a significant complication that requires careful monitoring after gastric ESD for early gastric cancer, particularly in patients with postoperative gastric conditions.

Abstract
Endoscopic submucosal dissection (ESD) is the first treatment option for superficial squamous cell carcinoma of the esophagus (SSCE). Salvage endoscopic treatment for recurrent advanced esophageal cancer after chemoradiotherapy (CRT) has been reported. However, there are few reports on long-term prognosis after salvage endoscopic treatment in Japan. The present study investigated long-term treatment results after conventional ESD for SSCE and after salvage endoscopic treatment for locally recurrent lesions after CRT. Outcomes of esophageal ESD were retrospectively investigated at Nagasaki University Hospital and long-term prognosis after salvage endoscopic treatment for locally recurrence lesions after CRT was examined. The en-bloc curative resection rate was 89.5% (606/676) for conventional ESD. The 5-year cause-specific survival rate (CSS) was 98.5%. A total of 77 patients underwent salvage endoscopic treatment [ESD or photodynamic therapy (PDT)] for locally recurrent lesions after CRT. The 3-year CSS was 81.3 and 77.1% for salvage ESD and salvage PDT, respectively. SSCE management using ESD yielded high en-bloc curative resection and survival rates. Overall, establishing salvage endoscopic treatment made long-term control of the underlying disease possible, while also maintaining the quality of life for patients with recurrent advanced esophageal cancer deeper than patients with T1b who underwent CRT and patients with recurrence after additional CRT following ESD.

Abstract
OBJECTIVES To describe an endoscopic technique named 'underwater endoscopic mucosal resection (UEMR) with submucosal injection and marking (UEMR-SIM)' and to evaluate the therapeutic characteristics of superficial non-ampullary duodenal epithelial tumors (SNADETs) < 20 mm vis-a-vis classical EMR (CEMR) and UEMR techniques. MATERIALS AND METHODS This retrospective study included 103 consecutive SNADET patients (103 lesions) who underwent CEMR, UEMR, or UEMR-SIM. The UEMR-SIM procedure included (1) marking and submucosal injection, (2) filling of the duodenal lumen with 0.9% saline, (3) snaring of the lesion, and (4) electrosurgical removal. The procedural outcomes were compared between the UEMR-SIM and other-procedure groups. RESULTS The en bloc resection rate was significantly higher in the UEMR-SIM group (100%) than in the CEMR group (76.8%) (p = 0.015) but was not statistically different between the UEMR-SIM and UEMR groups (88.0%) (p = 0.236). The R0 resection rate was significantly higher in the UEMR-SIM group (90.9%) than in the UEMR group (48.0%) (p = 0.001) but was not statistically different between the UEMR-SIM and CEMR groups (76.8%) (p = 0.209). CONCLUSIONS Our study indicates that the proposed method, UEMR-SIM for SNADETs, is feasible to achieve a high R0 resection rate and a potentially low local recurrence rate.

Abstract
A 26-year-old Japanese woman was admitted with a 1-month history of diarrhea, a high fever for a few days, and exacerbation of dyspnea. She was treated with an antifibrotic drug and long-term oxygen therapy for Hermansky-Pudlak syndrome-related pulmonary fibrosis. New ground-glass attenuation appeared on chest computed tomography (CT), and a colon biopsy showed an inflammatory cell accumulation with a high titer of myeloperoxidase (MPO)-specific anti-neutrophil cytoplasmic antibodies (ANCA). Systemic inflammation related to MPO-ANCA titer elevation was suspected. Steroid pulse therapy and intravenous cyclophosphamide improved chest CT findings and diarrhea. Therefore, immunosuppressant treatment should be considered for systemic inflammation related to MPO-ANCA.

Abstract
BACKGROUND Fibrosis is the most important pathological feature in predicting development of Hepatocellular carcinoma (HCC). However, the incidence rate of HCC in patients with non-alcoholic fatty liver disease (NAFLD) is relatively low. We evaluated phenotypic histological features to differentiate HCC from non-HCC in patients with non-tumor lesions of cirrhotic livers. METHODS Seventeen patients with NAFLD who underwent liver transplantation were enrolled. FibroNest was used to quantify histological phenotypes of non-tumor fibrosis lesions. Quantification included collagen content and structure traits, fiber morphometric traits, and fibrosis architecture traits. Each trait was described by up to seven quantitative fibrosis traits (qFTs). Among the qFTs measured in each specimen, those that described most of the variability between consecutive groups were automatically detected and combined into a normalized Phenotypic Composite Fibrosis Score (Ph-CFS). We trained FibroNest to identify the principal traits that differentiate HCC from non-HCC. RESULTS HCC was found in 8 cases and non-HCC in 9 cases. The Ph-CFS significantly differentiated HCC from non-HCC (4.6 vs. 5.9, p < 0.05). Individual qFTs for morphometric features including collagen fiber length, width, perimeter, and area denoted significant differences between HCC and non-HCC. The Ph-CFS could be used to distinguish HCC (Ph-FCS < 5.0) from non-HCC (Ph-FCS ≥ 5.0) with 75% sensitivity and 100% specificity. CONCLUSION In patients who underwent liver transplantation, fibrotic histological phenotypes in non-tumor lesions appeared to be different between HCC and non-HCC. Phenotypic analysis of collagen in non-tumor lesions might be an effective and automated method to distinguish HCC from non-HCC on histopathology imaging.

Abstract
Sarcopenia comprises a low skeletal muscle index (SMI) and low muscle strength (MS) or low physical function. Many sarcopenia biomarkers have been reported. With Crohn’s disease (CD), a low SMI is predictive of intestinal complications. Therefore, many CD studies have reported that sarcopenia is defined by SMI alone. This study investigated the sarcopenia frequency by assessing the SMI and MS of Japanese patients with CD and biomarkers predicting a low SMI. We evaluated the SMI using a bioelectrical impedance analysis, handgrip strength, and C-reactive protein, albumin, interleukin-6, tumor necrosis factor-α, growth differentiation factor (GDF)-8, and GDF-15 levels as biomarker candidates for 78 CD patients at our hospital. Sarcopenia and a low SMI were observed in 7.7% and 42.3% of the patients, respectively. There was a significant difference in the GDF-15 levels of the low SMI group and normal group according to the multivariate analysis (P = 0.028; odds ratio [OR], 1.001; 95% confidence interval [CI] 1.000–1.002). When evaluated by sex, males exhibited a negative correlation between the GDF-15 level and SMI (Pearson’s r = − 0.414; P = 0.0031), and the multivariate analysis indicated a significant difference in the GDF-15 levels (P = 0.011; OR, 1.001; 95% CI 1.000–1.002).

Abstract
The differential cross sections of the Σ^{-}p→Λn reaction were measured accurately for the Σ^{-} momentum (p_{Σ}) ranging from 470 to 650 MeV/c at the J-PARC Hadron Experimental Facility. Precise angular information about the Σ^{-}p→Λn reaction was obtained for the first time by detecting approximately 100 reaction events at each angular step of Δcosθ=0.1. The obtained differential cross sections show a slightly forward-peaking structure in the measured momentum regions. The cross sections integrated for -0.7≤cosθ≤1.0 were obtained as 22.5±0.68 [statistical error(stat.)] ±0.65 [systematic error(syst.)] mb and 15.8±0.83(stat)±0.52(syst) mb for 470<p_{Σ}(MeV/c)<550 and 550<p_{Σ}(MeV/c)<650, respectively. These results show a drastic improvement compared with past measurements of the hyperon-proton scattering experiments. They will play essential roles in updating the theoretical models of the baryon-baryon interactions.

Abstract
A new hyperon-proton scattering experiment, dubbed J-PARC E40, was performed to measure differential cross sections of the Σ+p, Σ−p elastic scatterings and the Σ−p → Λn scattering by identifying a lot of Σ particles in the momentum ranging from 0.4 to 0.8 GeV/c produced by the π±p → K+Σ± reactions. We successfully measured the differential cross sections of these three channels with a drastically improved accuracy with a fine angular step. These new data will become important experimental constraints to improve the theories of the two-body baryon-baryon interactions. Following this success, we proposed a new experiment to measure the differential cross sections and spin observables by using a highly polarized Λ beam for providing quantitative information on the ΛN interaction. The results of three Σp channels and future prospects of the Λp scattering experiment are described.

Abstract
Abstract
Background
Atrioventricular valve (AVV) regurgitation enormously affected the survival outcome of the patients with congenital heart disease (CHD). However, the image quality by use of transthoracic echocardiography has not reached a level that is sufficient, and also, three-dimensional echocardiography, which is useful to clarify complex AVV anatomy, cannot be applied for the patients less than 15kg, to guide for the AVV repair in pediatric patients. We try to show surgeons more precise three-dimensional images about an AVV by using intraoperative pericardial three-dimensional echocardiography (IP3DE) and improve the surgical outcome.
Purpose
To determine the efficacy of IP3DE by assessing the surgical outcome of an AVV repair and re-intervention rate.
Method
Eighty-five patient with CHD who underwent atrioventricular repair with significant regurgitation (Grade 2–4+) before operation were divided into two groups imaged IP3DE or not, in our hospital from 1993 to 2020. We assessed the surgical outcome and re-intervention rate between two arms and re-evaluate AVV images before surgery compared to the IP3DE.
Result
IP3DE was performed in forty-six patients (IP3DE group) and thirty-nine patients were not (control group). Median age at AVV repair was 3.0/2.8 years, respectively. The AVV was tricuspid (n=25), mitral (n=41), or common (n=19). The IP3DE group had a significantly higher improvement in regurgitation of AVV (IP3DE: Grade 3.2±0.3 → 1.7±0.3 vs Control: Grade 2.8±0.3 → 1.8±0.3, p<0.05). Fifty-nine percent of the IP3DE group was successful outcome (Grade<1+ after repair). There was no significant difference in the rate of re-intervention after surgery between two groups. In multivariate analysis, using IP3DE contributed to successful outcome for AVV repair (OR: 4.66, 95% CI: 1.46–14.8, p<0.01). The different and/or additional anatomical AVV findings were obtained in sixty-one percent of patients by the IP3DE.
Conclusion
IP3DE contributes to successful outcome for AVV repair by obtaining further information on complicated AVV anatomy in congenital heart disease. IP3DE also enables both cardiovascular surgeons and cardiologists to share the accurate and detail “surgeon's view” in the operating room for planning of AVV repair.

Abstract
BACKGROUND/AIM P53-binding protein 1 (53BP1) is one of the DNA damage response (DDR) molecules. This study aimed to assess 53BP1 expression by immunofluorescence (IF) as a biomarker to differentiate between oral squamous epithelial lesions (OSELs). MATERIALS AND METHODS We analyzed 129 archival oral biopsy samples, including 18 benign squamous lesions (BSLs), 37 low-grade dysplasias (LGDs), 22 high-grade dysplasias (HGDs), and 52 oral squamous cell carcinomas (OSCCs). 53BP1 and Ki-67 expressions were examined by double IF to assess the type of 53BP1 expression. RESULTS We found that OSCC exhibited several 53BP1 nuclear foci, particularly high-DNA damage response (HDDR) and large focus (LF)-type, suggesting the presence of endogenous DNA double-strand breaks in the cancer genome, which could disrupt DDR and induce genomic injury. We also found a difference in 53BP1 expression between LGD and HGD, but not between BSL and LGD. Among the Ki-67-positive cells, HDDR- and LF-type expressions were higher in OSELs of higher grades. CONCLUSION 53BP1 expression can be a valuable biomarker for OSELs to help estimate the grade of oral epithelial dysplasia.

Abstract
Inflammatory bowel diseases (IBDs), including ulcerative colitis (UC) and Crohn’s disease (CD), are chronic intestinal diseases of unknown etiology that present with variable disease extents and outcomes. The use of biomarkers for the diagnosis and management of IBDs is considered beneficial. Palmitoleic acid (PO) is an adipose tissue-derived mono-unsaturated free fatty acid that potentially serves as a lipokine in metabolic and inflammatory diseases. The aim of this study was to investigate the significance of PO levels in the serum of patients with UC and CD. The study included patients with UC (n = 22), patients with CD (n = 35), and controls (n = 22). The levels of serum PO were analyzed using gas chromatography. The association of serum PO levels with the clinical features and disease outcomes in IBD was examined. Serum PO levels were significantly higher in patients with CD than in controls, whereas no difference in these levels was observed between patients with UC and controls. Serum PO levels were significantly associated with the CD activity index. Additionally, high serum PO levels were associated with an increased risk of surgical intervention requirement during follow-up. In a pilot study with a few patients, high PO levels were observed in the mesenteric tissue in the active disease site of patients with CD (n = 7) compared with those with colon cancer (n = 6). Elevated serum PO levels might serve as a marker for local inflammation and prognosis in patients with CD.

Abstract
Endoscopic submucosal dissection (ESD) has become the first-line treatment for early gastric neoplasms; however, a subset of patients treated by this method develop aspiration pneumonia. We conducted a comprehensive prospective analysis of the factors contributing to post-ESD aspiration pneumonia in early gastric neoplasms in this study, with special focus on whether pre-treatment oral care can prevent aspiration pneumonia. Sixty-one patients who underwent ESD for gastric neoplasms were randomly assigned to the oral care or control groups. ESD was performed under deep sedation. Of 60 patients whose data were available for analysis, 5 (8.3%) experienced pneumonia confirmed either by chest radiography or computed tomography. Although no difference in the rate of pneumonia was found between the control and oral care groups, the post-oral care bacteria count was significantly higher in the saliva of patients who developed pneumonia compared to those without pneumonia. In addition, the presence of vascular brain diseases and the dose of meperidine were also significantly associated with the occurrence of pneumonia. These results suggest that the number of oral bacteria as well as pre-existing vascular brain diseases and high-dose narcotics can affect the incidence of post-ESD pneumonia.

Abstract
BACKGROUND AND AIM Elimination of hepatitis B virus (HBV) is infrequently achieved with current therapies. Therefore, more effective anti-HBV therapy is needed. We previously reported that geranylgeranylacetone (GGA) showed anti-hepatitis C virus activity in human hepatoma cells. In this study, we examined the anti-HBV activity of GGA. METHODS We used HepG2.2.15.7 cells, PXB cells infected with HBV, Huh7 cells transfected with linear HBV, and PLC/PRF/5 cells as HBV-infected hepatocyte models. After GGA treatment, HBV-related antigen was measured by chemiluminescent immunoassay. HBV-related mRNA was examined by Northern blot. cccDNA and endoplasmic reticulum stress markers were measured by real-time polymerase chain reaction. The activities of HBV promoters and enhancer regions were examined using luciferase vectors. RESULTS After GGA treatment, hepatitis B surface antigen and hepatitis B e antigen secretion was decreased in all HBV-infected hepatocyte models. HBV-related mRNA was also decreased by GGA treatment, although cccDNA levels were not affected. Additionally, the activity of HBV S1 and S2 promoter region and Enhancer 1/Enhancer 2/core promoter region was reduced by GGA treatment. The mRNA expression of the main transcription factors, hepatocyte nuclear factor 3 and 4 and CCAAT/enhancer binding protein, was also decreased. Further, the expression levels of endoplasmic reticulum stress markers were increased by GGA treatment, which reflected the change in HBV-related antigen secretion. CONCLUSIONS Geranylgeranylacetone treatment reduces HBV-related protein levels by suppressing comprehensive downregulation of HBV promoter and enhancer activity, which might be caused by decreased hepatic transcription factor expression. GGA treatment may enhance anti-HBV effects in combination with other therapies.

Abstract
We have previously reported that the expression of p53-binding protein 1 (53BP1) in nuclear foci (NF), a marker reflecting DNA damage response (DDR), detected using immunofluorescence (IF) is useful to estimate the malignant potency of diverse cancers. In this prospective study, we clarified the impact of 53BP1 expression via IF as a biomarker to differentiate thyroid follicular tumors (FTs) with liquid-based cytology (LBC). A total of 183 consecutively obtained-LBC samples, which were preoperatively suspected as FTs, were analyzed. Before histological diagnosis, the type of 53BP1 immunoreactivity in LBC was classified as follows: low DDR type, one or two NF; high DDR type, three or more NF; large foci type, larger than 1.0 μm; abnormal type, intense nuclear staining. Among the 183 cases, 136 cases were postoperatively diagnosed as FTs, including adenomatous goiter (AG, n = 30), follicular adenoma (FA, n = 60), FT-uncertain malignant potency (FT-UMP, n = 18), and follicular carcinoma (FC, n = 28), and 47 cases were diagnosed as tumors other than FTs or technically inadequate materials. Total 136 FT cases were collated with the type of 53BP1 immunoreactivity in LBC. The mean incidence expressing abnormal 53BP1 expression was significantly higher in FC than FA (9.5% vs 2.6%, P-value < 0.001). When adopting 4.3% as a cut-off value to distinguish FC from FA, the sensitivity, specificity, positive predictive value, and negative predictive value were 89.3, 83.3, 71.4, and 94.3%, respectively. Therefore, IF analysis of 53BP1 expression can be employed as a novel technique to diagnose FTs and to distinguish between different types of FTs using LBC.

Abstract
In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ^{-} absorption event was observed which decayed into twin single-Λ hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as Ξ^{-}+^{14}N→_{Λ}^{10}Be+_{Λ}^{5}He. For the binding energy of the Ξ^{-} hyperon in the Ξ^{-}-^{14}N system a value of 1.27±0.21 MeV was deduced. The energy level of Ξ^{-} is likely a nuclear 1p state which indicates a weak ΞN-ΛΛ coupling.

Abstract
Purpose of review: To provide an update on latest advances in treatment of cholangiocarcinoma. Recent findings: Incidence of cholangiocarcinoma has been increasing over the past decade. A better understanding of the genetic landscape of cholangiocarcinoma and its risk factors resulted in earlier diagnosis and treatment option expansion to targeted therapy with FGFR inhibitors, and liver transplantation for early perihilar cholangiocarcinoma and early intrahepatic cholangiocarcinoma. IDH1/2 inhibition for intrahepatic cholangiocarcinoma is an emerging targeted therapy approach. Data supports benefits of adjuvant therapy for a subset of patients undergoing surgical resection. Approaches combining different treatment modalities such as chemotherapy, surgery, radiation therapy appear promising. Summary: Earlier diagnosis and genetic characterization provided additional treatment options for patients with previously incurable cholangiocarcinoma. A precision medicine approach with a focus on actionable genetic alterations and combination of treatment modalities are actively being explored and will further improve outcomes in our patients with cholangiocarcinoma.

Abstract
Gastroesophageal reflux disease (GERD) in systemic sclerosis (SSc) can significantly reduce a patient's quality of life. GERD in SSc is occasionally resistant to conventional anti-acid treatment. Vonoprazan is an H+/K+-ATPase blocker that is approved in Japan for treatment of GERD. The aim of the present study was to evaluate the efficacy of vonoprazan in SSc-related GERD. The frequency scale for symptoms of GERD (FSSG) scores were collected before and after vonoprazan treatment in 15 SSc patients with GERD. Additionally, endoscopic esophagogastroduodenoscopy was performed in select patients. Conventional proton pump inhibitors or histamine-2 receptor antagonists had been previously administered in 93% (14/15) of the patients. Although the baseline esophagogastroduodenoscopy examination did not show severe erosion in the majority of patients, the mean total FSSG score before vonoprazan treatment was notably high (25.2±10.7) compared to a normal score of <8. After vonoprazan treatment, the FSSG score decreased to 9.6±7.0. The mean improvement rate of the total FSSG, acid reflux and dysmotility scores were 60.8±21.2% (P=0.0004), 67.3±24.8% (P<0.0001) and 55.4±26.0% (P=0.0022), respectively. These results suggest that vonoprazan may be a potentially effective treatment for GERD in patients with SSc.

Abstract
Background
The peak oxygen uptake (VO2) evaluated by the cardiopulmonary exercise test (CPX) is an established marker of exercise capacity in patients with heart failure (HF). In particular, peak VO2 <14 ml/kg/min is used to be one of the criteria for heart transplantation. However, given exercise intolerance in patients with HF, it is difficult for refractory HF patients to reach sufficient exercise load. A recent report has highlighted significant impact of right ventricular (RV) function on mortality and urgent heart transplantation. Taken together, we hypothesized that the assessment of RV function was helpful to predict exercise capacity by using low-load exercise stress echocardiography (low-load ESE) in patients with HF.
Purpose
We evaluated whether RV dysfunction assessed by the low-load ESE determined a low peak VO2 <14 ml/kg/min in patients with HF.
Methods
We studied 67 consecutive hospitalized patients with HF (mean age, 65 years; 75% male; mean LV ejection fraction, 36%) who underwent ESE and CPX after stabilized HF condition, and the time interval of CPX and ESE tests was within 48 hours. CPX was performed using an upright cycle ergometer by a ramp protocol, while ESE was performed using ergometer in semi-supine position and the workload was generally increased by 25 watts every 3 minutes. The low-load ESE was defined as the 25 watts exercise. The increments of RV s' velocity at tricuspid annulus and RV strain in the free wall were considered as a preservation of RV contractile reserve. Among the study population, 26 patients were performed right heart catheterization and RV dP/dt/Pmax was estimated as an invasive marker of RV contractility.
Results
The achieved intensity of exercise was 50.4±21.0 watts, and all patients completed the low-load ESE. The invasive study showed that the change of RV s' velocity during the low-load ESE significantly correlated with RV dP/dt/Pmax (r=0.706, p<0.001). As shown in Figure, the non-invasive parameters of RV contractile reserve during the low-load ESE were significantly correlated with peak VO2 (RV s' velocity: r=0.787, p<0.001; RV strain: r=0.244, p=0.047). ROC analysis showed that the change of RV s' velocity during the low-load ESE correctly identified patients with peak VO2 <14 ml/kg/min (AUC=0.95, sensitivity 92.3%, specificity 85.2%). In terms of inter- and intra-observer variabilities, ICCs of the change of RV s' velocity were 0.86 and 0.96, and ICCs of the changes of RV strain were 0.63 and 0.70, respectively.
Conclusion
The change of RV s' velocity during the low-load ESE could determine exercise tolerance in patients with HF. The assessment of RV contractile reserve might be clinically useful to discriminate high risk HF patients.

Abstract
BACKGROUND Transanal (Ta) pelvic exenteration is a promising, minimally invasive method for treating locally advanced colorectal cancer. However, since it is technically difficult to perform, Ta pelvic exenteration is rarely reported in locally advanced T4 rectal cancer cases. The aim of this study was to evaluate the feasibility of transabdominal laparoscopy-assisted Ta pelvic exenteration. METHODS Six patients (4 males and 2 females) had laparoscopy-assisted Ta total or posterior pelvic exenteration for locally advanced or recurrent colorectal cancer cases at the Nagasaki University Hospital between September 2018 and August 2019. Clinical and pathological outcomes were measured and analyzed. RESULTS The median operation time and intraoperative blood loss were 481 (range 456-709) minutes and 352.5 (range 257-1660) ml, respectively. R0 resection was achieved in all cases, and no patient required open surgery. Two patients had grade 3 complications (Clavien-Dindo) or higher. There was no mortality, and no reoperation was required. CONCLUSIONS The results suggest that laparoscopic-assisted Ta pelvic exenteration is an acceptable procedure, may help overcome the current technical difficulties, and may improve outcomes in patients with locally advanced rectal cancer.

Abstract
While retrospective studies have compared the efficacy of anti–tumour necrosis factor (TNF) agents and tacrolimus (TAC) in ulcerative colitis (UC), information regarding first-time use of these agents is limited. The aim of our study was to investigate the short- and long-term efficacy of anti-TNF agents [adalimumab (ADA) and infliximab (IFX)] and TAC in anti-TNF agent- and TAC-naïve steroid-refractory UC patients. We evaluated 150 steroid-refractory UC patients receiving anti-TNF agents (IFX: n = 30, ADA: n = 41) or TAC (n = 79) at eight institutions in Japan. Clinical response rates at 8 weeks were 73.2% and 75.9% while remission rates were 30.1% and 25.3% in the anti-TNF and TAC groups, respectively. Logistic regression analysis showed the male sex and higher C-reactive protein to be independent factors for response to anti-TNF agents and TAC, respectively. Use of TAC was an independent factor for relapse. No differences in response to the treatment or relapse were observed between IFX and ADA. In conclusion, TAC and anti-TNF agents promoted similar short-term effects, but anti-TNF agents ensured better long-term outcomes at first-time treatment of steroid-refractory UC patients.

Abstract
Human T-cell leukemia virus type I (HTLV-1) infection and adult T-cell leukemia-lymphoma (ATL) have been shown to cause immunodeficiency. However, only a few cases have been reported on the development of Epstein-Barr virus positive-diffuse large B-cell lymphoma (EBV-DLBCL) in HTLV-1 carriers or in patients with ATL. Here we report a case of a female HTLV-1 carrier who developed cytomegalovirus (CMV) retinitis. During the CMV retinitis treatment, she developed a liver tumor. The diagnosis of composite ATL and EBV-DLBCL was made by tumor biopsy. The patient also suffered from pulmonary cryptococcosis and invasive pulmonary aspergillosis at the time of chemotherapy initiation. She had repeated CMV antigenemia and bacterial sepsis during the course of chemotherapy, and she died of bacterial sepsis. HTLV-1 carriers who are complicated with opportunistic infections should be carefully observed not only for ATL development but also for the development of EBV-DLBCL and associated infectious complications.

Abstract
Background Cutaneous pilomatrical carcinosarcoma (CS) is a very rare biphasic tumor composed of admixed epithelial and mesenchymal malignant cells, with limited information on its pathogenesis. We report a case of pilomatrical CS of the scalp with comparative immunohistochemical and molecular analysis together with a review of the literature. Case presentation A 74-year-old woman presented with a rapidly growing long-standing tumor of the scalp. The tumor was surgically resected. Histologically, the tumor was 25 mm in diameter, and was composed of carcinoma showing a clear pilomatrical differentiation and sarcoma with pleomorphic spindle cells and giant cells. Both epithelial and mesenchymal components shared focal cytoplasmic and/or nuclear accumulation of β-catenin based on immunohistochemical analysis, although a mutation of exon 3 of the CTNNB1 gene was not detected. Fluorescence in situ hybridization analysis revealed gains of chromosomes 9p21, 3, and 7 in both the epithelial and sarcomatous components. Conclusions The current case demonstrated characteristic findings of pilomatricoma and further evidence of partial clonality between the carcinomatous and sarcomatous component, suggesting the possibility of malignant transformation of pilomatricoma. Rapid growth of a pilomatrical tumor should warrant the development of a malignant tumor, including CS.

Abstract
Background
Abnormal atrioventricular conduction and functional right ventricular (fRV) dysfunction are common in patients with Ebstein anomaly (EA). However, the relation of fRV dyssynchrony to fRV function in EA has not been studied.
Purpose
We hypothesized that fRV electromechanical dyssynchrony is associated with fRV remodeling, dysfunction and exercise intolerance in EA patients.
Methods
Non-operated EA patients and age-matched controls prospectively underwent echocardiography, cardiovascular magnetic resonance imaging (CMR) and cardiopulmonary exercise testing to quantify RV remodeling, dysfunction and exercise capacity, respectively. The relation of these to fRV dyssynchrony was investigated. RV mechanical dyssynchrony was defined by early septal activation (right-sided septal flash), RV lateral wall prestretch/late contraction, postsystolic shortening, and the maximal intra-RV delay (difference in time to peak of lateral basal RV and apical septal segments) using 2-dimensional strain echocardiography.
Results
Thirty-five EA patients (age 31.6 ± 17.3 years, 19 female) and 35 age-matched controls were studied. QRS duration and intra-fRV mechanical delay were significantly longer in EA compared with controls. 19/35(54%) of EA patients had early activation of septal segments with simultaneous stretching and consequent late activation and post-systolic shortening of RV lateral segments. QRS duration correlated with fRV end-diastolic (fRVEDVI, r = 0.46, P <0.01) and end-systolic indexed volumes (fRVESVIr = 0.57, P <0.001). Intra-fRV delay correlated with RV global longitudinal strain (GLS, r=-0.45,P <0.05) and RV fractional area change (r=-0.56, P <0.01). Intra-fRV delay was also associated with fRVEDVI (r = 0.43, P <0.05), fRVESVI (r = 0.63, P <0.001), fRVEF (r=-0.46,P <0.05) and predicted peak VO2 (r=-0.39, P < 0.05). EA patients with versus without a septal flash had lower fRVEF (45 ± 11 vs. 54 ± 8%, p < 0.05) and predicted peak VO2 (0.71 ± 0.19 vs. 0.92 ± 0.33, p < 0.05).
Conclusions
In EA, fRV electromechanical dyssynchrony is associated with fRV remodeling, dysfunction and impaired exercise capacity and may constitute a therapeutic target.

Abstract
BACKGROUND AND AIM pancreatic juice cytology (PJC) is an important predictor of malignant intraductal papillary mucinous neoplasm (IPMN). This study aimed to determine the role of PJC for the prediction of malignant IPMN (intraductal papillary mucinous cancer [IPMC]). METHODS medical records of IPMN patients who underwent surgery between 2012 and 2016 at the Nagasaki University Hospital were reviewed. Patients who underwent preoperative PJC were classified as high risk stigmata (HRS), worrisome features (WF) and no-criteria, based on imaging criteria. PJC class III or higher was considered as positive and only invasive IPMN was defined as IPMC. PJC was validated in each group with regard to sensitivity, specificity, accuracy with the corresponding 95% confidence intervals (95% CI) and area under receiver operating curve (AUROC) analysis. A p-value of < 0.05 was considered as statistically significant. RESULTS preoperative pancreatic juice was obtained in 33/52 IPMN patients; only patients with adequate aspirate for cytology (n = 29) were included. In the HRS group (n = 9), 4/6 non-IPMC had a negative PJC and 3/3 IPMC had a positive PJC. In the WF group (n = 17), 9/11 non-IPMC had a negative PJC and 3/6 IPMC had a positive PJC. Adding PJC to imaging results improved the AUROCs of HRS and WF from 0.63 and 0.62 to 0.83 and 0.66, respectively. PJC was negative in all no-criteria cases (n = 3; one IPMC and two non-IPMC). In all 29 patients, PJC sensitivity was 60% (95% CI: 26%-88%), specificity was 79% (95% CI: 54%-94%), accuracy was 72% (95% CI: 63%-89%) and the AUROC was 0.69 (p = 0.03). CONCLUSION PJC is a statistically significant IPMC predictor that can improve the validity of imaging for IPMC prediction.

Abstract
BACKGROUND Abnormal DNA damage response (DDR) leads to genomic instability and carcinogenesis. P53-binding protein 1 (53 BP1), a DDR molecule, is known to accumulate at the sites of DNA double-strand breaks. The aim of this study was to analyze the expression pattern of 53 BP1-nuclear foci (NF) in esophageal neoplasms in order to visualize the state of DDR in esophageal carcinogenesis and to clarify its significance in the molecular pathology of the disease. METHODS A total of 61 lesions from 22 surgically resected samples of esophageal cancer, including histologically normal squamous epithelium, low-grade intraepithelial neoplasia (LG-IN), high-grade intraepithelial neoplasia (HG-IN), carcinoma in situ (CIS), and invasive squamous cell carcinoma (SCC), were included in the study. 53 BP1 and Ki-67 expression were analyzed by double-labeled immunofluorescence. RESULTS The number of discrete 53 BP1-NF increased as the tumor progressed from normal epithelium through LG-IN, HG-IN, CIS, and SCC. 53 BP1-NF larger than 1 μm in diameter (large foci), indicating intensive DDR, also showed a stepwise increase during the progression of carcinogenesis. Of note, large foci of 53 BP1 were found in significantly higher numbers in HG-IN than in LG-IN. Furthermore, localization of 53 BP1-NF in Ki-67-positive cells, indicating the abnormal timing of DDR, also increased with malignancy progression. CONCLUSIONS 53 BP1-NF accumulation increases during cancer progression from LG-IN to HG-IN to CIS to SCC. Detection of 53 BP1-NF by immunofluorescence, especially large foci, is a feasible method of estimating DNA instability and the malignant potential of esophageal intraepithelial neoplasia.

Abstract
A γ-glutamyl hydroxymethyl rhodamine green probe (gGlu-HMRG) reacts with γ-glutamyltranspeptidase (GGT) and immediately produces fluorescence, is clinically applied for real-time cancers' visualization. Since Helicobacter pylori produces GGT, this study aimed to investigate whether gGlu-HMRG can be used to detect H. pylori infections. A wild-type H. pylori strain and the ggt gene-disrupted mutant were cultured and treated with gGlu-HMRG. This fluorescent probe assay was used to quantify GGT activity of H. pylori ex vivo using gastric biopsy specimens. The H. pylori diagnostic capabilities of the assay were determined from altered fluorescence intensity (FI) values at 5 min (FIV-5) and 15 minutes (FIV-15). Distinct fluorescence was identified in wild H. pylori strain, using gGlu-HMRG, whereas no fluorescence was observed in ggt gene-disrupted mutant strain. On ex vivo imaging of gGlu-HMRG, fluorescence intensity increased markedly with time in H. pylori-positive specimens; however, the H. pylori-negative specimens displayed a slight increase in FI. FIV-5 and FIV-15 differed significantly between H. pylori-positive and -negative specimens. FIV-15 differed significantly between H. pylori-positive and -eradicated group. This assay sensitivity and specificity were 75.0% and 83.3% in the antrum and 82.6% and 89.5% in the stomach body. GGT-activatable fluorescence probe is applicable for rapid diagnosis of H. pylori.

Abstract
Nonalcoholic fatty liver disease is a major liver disease that leads to cirrhosis and/or hepatocellular carcinoma in a subset of patients. The mechanism underlying disease progression is largely unknown. p53-binding protein 1 (53BP1) is a DNA damage response protein that rapidly localizes at the site of DNA double-strand breaks. In this study, we investigated nuclear 53BP1-positive foci formation as an indicator of DNA double-strand breaks in human nonalcoholic fatty liver disease liver tissues by immunofluorescence microscopy. A total of 52 liver tissue samples, including 43 nonalcoholic fatty liver disease samples and 9 controls, were studied. Our results show that the number of abnormal 53BP1-positive foci in hepatocytes (defined as three or more discrete nuclear foci and/or large foci greater than 1 μM) was significantly increased in nonalcoholic fatty liver disease patients compared to that in controls, both in nonalcoholic fatty liver (p < 0.01) and nonalcoholic steatohepatitis patients (p < 0.01). The number of large foci was significantly increased in the nonalcoholic steatohepatitis cases compared to that in the nonalcoholic fatty liver cases (p < 0.05) and correlated with increased stage of fibrosis. The number of large-foci-expressing hepatocytes was positively correlated with increased age (p < 0.01) and negatively correlated with serum platelet count (p < 0.05). In addition, we performed an in vitro assay using rat hepatocytes treated with the saturated free fatty acid palmitate. Treatment appeared to augment the number of abnormal foci, indicating an induction of double-strand breaks in the hepatocytes through free fatty acid treatment in a caspase-dependent manner. This study demonstrates that 53BP1-positive nuclear foci formation is associated with disease progression in nonalcoholic fatty liver disease patients. Analysis of 53BP1 expression might be a feasible technique to estimate genomic instability in nonalcoholic fatty liver disease.

Abstract
Initial esophagogastroduodenoscopy (EGD) shows segmental contractions right above the gastro‐esophageal junction, which may be related to the symptoms. A clip was applied during a previously performed manometry. There was no evidence of stricture. High‐resolution manometry before peroral endoscopic myotomy shows a hypercontractile esophagus expressed as distal contractile integral > 8000 mmHg cm s two times out of 10.

Abstract
BACKGROUND Maintenance of mucosal healing is recommended during the treatment of ulcerative colitis (UC). However, symptoms of UC often do not reflect mucosal disease activity. Fecal markers such as calprotectin, lactoferrin, and hemoglobin have been reported to correlate well with the Mayo endoscopic subscore (MES) and are being considered alternative monitoring tools in endoscopy. Ulcerative Colitis Endoscopic Index of Severity (UCEIS) is a new and more detailed endoscopic scoring system compared to MES. Furthermore, magnifying endoscopic stratification (ME) based on alterations in the mucosal surface pit patterns is noted in UC. However, the association between fecal markers and UCIES and magnifying endoscopy is relatively unexplored. SUMMARY This study investigated the association between the aforementioned fecal markers and MES, UCEIS, and ME in patients with UC in clinical remission. This prospective study included 60 patients with UC in clinical remission who underwent colonoscopy at the Nagasaki University Hospital between June 2015 and November 2016. A significant correlation was observed between MES and all fecal markers. Notably, the fecal markers correlated well with UCEIS (calprotectin Spearman's correlation coefficient [r] = 0.54, p < 0.0001; lactoferrin r = 0.56, p < 0.0001; and hemoglobin r = 0.43, p < 0.001). Furthermore, ME findings correlated significantly with calprotectin (r = 0.50, p = 0.0002) and lactoferrin (r = 0.46, p = 0.0006) levels and slightly with hemoglobin (r = 0.28, p = 0.043) levels. Moreover, each cutoff level of fecal calprotectin, lactoferrin, or hemoglobin had a high sensitivity and specificity for the detection of MES = 0, UCEIS = 0, ME = A, for predicting mucosa healing. Key Messages: Fecal markers correlated not only with MES but also with UCEIS and ME and should be useful for monitoring patients with UC in clinical remission.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is an emerging liver disease worldwide. In subset of patients, NAFLD progresses to its advanced form, nonalcoholic steatohepatitis (NASH), which is accompanied with inflammation and fibrosis. Saturated free fatty acid-induced hepatocyte apoptosis is a feature of NASH. Death signaling in NASH does not always result in apoptosis, but can alternatively lead to the survival of cells presenting signs of pro-inflammatory and pro-fibrotic signals. With the current lack of established treatments for NASH, it is important to understand the molecular mechanisms responsible for disease development and progression. This review focuses on the latest findings in hepatocyte death signaling and discusses possible targets for intervention, including caspases, death receptor and c-Jun N-terminal kinase 1 signaling, oxidative stress, and endoplasmic reticulum stress, as well as epigenomic factors.

Abstract
We report on the first observation of γ rays emitted from an sd-shell hypernucleus, _{Λ}^{19}F. The energy spacing between the ground state doublet, 1/2^{+} and 3/2^{+} states, of _{Λ}^{19}F is determined to be 315.5±0.4(stat)_{-0.5}^{+0.6}(syst) keV by measuring the γ-ray energy of the M1(3/2^{+}→1/2^{+}) transition. In addition, three γ-ray peaks are observed and assigned as E2(5/2^{+}→1/2^{+}), E1(1/2^{-}→1/2^{+}), and E1(1/2^{-}→3/2^{+}) transitions. The excitation energies of the 5/2^{+} and 1/2^{-} states are determined to be 895.2±0.3(stat)±0.5(syst) and 1265.6±1.2(stat)_{-0.5}^{+0.7}(syst) keV, respectively. It is found that the ground state doublet spacing is well described by theoretical models based on existing s- and p-shell hypernuclear data.

Abstract
BACKGROUND There have been great concerns about pediatric thyroid cancers after the accident at the Fukushima Daiichi Nuclear Power Plant in 2011. CASE PRESENTATION We report a case of a 7-year-old Japanese girl with sporadic papillary thyroid carcinoma (PTC) harboring an ETV6/NTRK3 rearrangement. The patient presented with tumors in both lobes and underwent thyroidectomy followed by radioactive iodine (RAI) ablation. Histopathology showed a classic type of PTC with cervical lymph node metastasis. CONCLUSIONS Genetic evaluation showed ETV6/NTRK3 fusion but no BRAF mutations or RET/PTC rearrangements. RET/PTC rearrangement and BRAF mutations often contribute to the pathogenesis of PTC; however, rearrangements of NTRK genes are relatively rare in pediatric PTC. Although NTRK rearrangement has been shown to often present unique pathological types and infiltrative architectures in the western population, such findings were not observed in this patient. Thus, the present case of classic PTC with ETV6/NTRK3 rearrangement highlights the disparate collection of clinic-pathological features compared to the trend in the western population. We therefore emphasize the need to further accumulate clinical as well as genetic data in pediatric PTCs.

Abstract
Background Geranylgeranylacetone (GGA), an anti-ulcer drug widely used in Japan, has attracted interest because of its various therapeutic effects. Therefore, we investigated the effects of GGA on human hepatic stellate cells (HSCs) in vitro and in a mouse model of liver fibrosis. Methods LX2, an immortalized human HSC line, was cultured and treated with GGA at concentrations up to 0.5 mM. After GGA treatment, changes in cellular morphology, apoptosis, and fibrosis-related gene expression were assessed. Male C57BL/6 J mouse model of carbon tetrachloride (CCl4)-induced liver fibrosis was treated with GGA. Liver fibrosis was evaluated using Sirius red staining and immunohistochemistry for α-smooth muscle actin (SMA). Results GGA decreased the density of LX2 and primary human hepatic stellate cells but not that of HepG2 cells (a human hepatoma cell line), which was employed as control. In addition, GGA decreased the expression of fibrogenic genes and increased that of C/EBP homologous protein (CHOP). It also induced endoplasmic reticulum (ER) stress and increased apoptosis. CHOP knockdown, however, failed to suppress the GGA-induced decrease in LX2 cell density, suggesting the involvement of additional molecules in ER stress–associated apoptosis. Expression of death receptor 5, mitogen-activated protein kinase, heat shock protein 70, and Akt, all of which affect the activity of stellate cells, was unchanged in relation to LX2 cell fibrogenic activity. In the mouse model of liver fibrosis, GGA decreased the extent of Sirius red staining and SMA expression. Conclusions GGA attenuated fibrogenic activity and induced apoptosis in cultured human HSCs, and suppressed liver fibrosis in mice, suggesting its potential as an agent for treating liver fibrosis.
