Abstract
AIM To investigate the clinical and radiological features to predict adhesion between vestibular schwannoma (VS) and brain tissue which is a critical risk factor for postoperative infarction and residual tumour. MATERIAL AND METHODS One hundred and seven consecutive VS surgeries were analysed. After excluding cases without contrast-enhanced (CE) computed tomography (CT), Koos grades 1 and 2, and cases with incomplete clinical data, 44 patients were finally included in the study. Enhancement of the tumour capsule on the brainstem side on CE-CT was defined as the CE-CT rim sign, which was analysed along with clinical characteristics, including tumour adhesion and postoperative complications. RESULTS Eight patients exhibited CE-CT rim signs; 17 had tumour adhesions. Four patients had postoperative infarction at the ipsilateral middle cerebellar peduncle; 18 exhibited postoperative infarction and/or residual tumour at the middle cerebellar peduncle. The CE-CT rim sign significantly correlated with tumour adhesion, postoperative infarction, and postoperative infarction and/or residual tumour in the cerebellar peduncle. Univariate regression analysis revealed that the CE-CT rim sign significantly correlated with tumour adhesion (odds ratio [OR] 6.81, 95% confidence interval [CI] 1.18-39.25, p=0.032) and postoperative infarction and/or residual tumour at the cerebellar peduncle (OR 6.00, 95% CI 1.04-34.31, p=0.044). CONCLUSION The CE-CT rim sign was identified in 18.2% of patients with VS and significantly correlated with tumour adhesion and postoperative complications, such as postoperative infarction and residual tumour. This study highlights the importance of the preoperative CE-CT rim sign in VS, which is predictive of tumour adhesion and postoperative complications.

Abstract
Although gastric endoscopic submucosal dissection (ESD) is widely used, the degree of difficulty varies greatly depending on the lesion. Since the multi-loop traction device (MLTD) has been suggested to shorten the procedure time in colorectal ESD, we examined the efficacy and safety of using the MLTD in gastric ESD. Thirty patients with gastric neoplasms were prospectively enrolled from February 2022 to December 2022, and the outcomes of ESD with the MLTD were evaluated. The primary outcomes were procedure time and dissection speed. The secondary outcomes were en bloc and R0 resection rates, MLTD attachment time, and complications of ESD with the MLTD. After excluding 1 patient, 29 patients (29 lesions) were treated by ESD with the MLTD. The median procedure time was 26 min (range, 9-210 min), and the median submucosal dissection speed was 39.9 mm2/min (12.4-102.7 mm2/min). The rate of en bloc resection was 100%, the median MLTD attachment time was 3 min (1-7 min), and none of the patients showed intraoperative or postoperative perforations. Thus, gastric ESD with the MLTD showed a favorable procedure time and dissection speed and an acceptable complication rate. Hence, the MLTD may be effective for gastric ESD.

Abstract
Objective The effect of sarcopenia on the prognosis of patients undergoing chemotherapy for unresectable pancreatic ductal adenocarcinoma remains largely unexplored. In this retrospective study, we investigated the relationship between sarcopenia and the prognosis of patients receiving first-line nanoparticle albumin-bound paclitaxel plus gemcitabine for unresectable pancreatic ductal adenocarcinoma. Methods We enrolled 251 patients with unresectable metastatic or locally advanced pancreatic ductal adenocarcinoma who had received chemotherapy between January 2015 and December 2020 at Kitasato University Hospital. Univariate and multivariate analyses were performed using the stratified Cox proportional hazards model to determine variables significantly associated with the progression-free and overall survival. Propensity score matching was performed to mitigate selection bias effects. Results In the propensity score-matched cohort, the progression-free and overall survival were not significantly different between the sarcopenia and non-sarcopenia groups (p=0.335, and 0.679 respectively). The skeletal muscle index decreased by 4.4% and 6.5% in the sarcopenia and non-sarcopenia groups, respectively, during the early treatment phase (p=0.084). There were no significant differences between groups with regard to major adverse events or drug toxicity occurrences. Both the progression-free and overall survival were significantly shorter in the skeletal muscle index loss group than in the non-skeletal muscle index loss group (p=0.026 and 0.045, respectively). Conclusion Skeletal muscle index loss during the initial treatment phase may be an early marker for the long-term prognosis of patients receiving nanoparticle albumin-bound paclitaxel plus gemcitabine as first-line treatment for unresectable pancreatic ductal adenocarcinoma.

Abstract
PURPOSE/OBJECTIVE(S) Radical treatment options for bulky unresectable locally advanced hepatocellular carcinoma (HCC) are limited. The purpose of this study is to evaluate the safety and efficacy of carbon-ion radiotherapy (C-ion RT) for bulky (≥4cm) locally advanced HCC. MATERIALS/METHODS We performed a retrospective cohort study of patients with bulky (≥4cm) locally advanced HCC treated by C-ion RT between April 2000 and March 2020 in our institution. The eligibility criteria for this study were: (1) the treatment protocols of 45.0-48.0 Gy/2 fractions or 52.8-60.0 Gy/4 fractions, which proven the safety and efficacy in the past clinical trials; (2) Tumors within 3 intrahepatic lesions and with a maximum tumor diameter of 4 cm or greater; (3) N0M0 status; (4) an Eastern Cooperative Oncology Group performance status of 0 to 2; (5) controllable ascites; (6) Child-Pugh grade was A or B. Overall survival (OS), progression-free survival (PFS), and local control rate (LC) were calculated by the Kaplan-Meier method, and Cox regression analysis was used for multivariate analysis. Adverse events were evaluated by CTCAE ver. 5.0. JMP® 12 (SAS Institute Inc., Cary, NC, USA) was used for all analyses. We defined p < 0.05 as statistically significant. RESULTS A total of 187 patients met the criteria and were evaluated. The median patient age was 73 years (range, 37-90), and 139 of 187 patients were male. Child-Pugh grade was A in 163 patients and B in 24. Modified albumin-bilirubin (mALBI) grade was 1 in 96 patients, 2a in 50, and 2b in 41. The number of HCV-related HCC cases was in 80, HBV in 32 and non-B and non-C in 75. In 51 patients, identification of vascular invasion to the first-order branch of the portal vein and/or major hepatic vein was confirmed. The median maximum tumor diameter was 5.1 cm (4.0-13.5 cm). In 76 patients, C-ion RT were treated for recurrence. With a median follow-up period of 25.9 months (range, 1.1-215.1), 2-year overall survival, progression-free survival and local control rates were 68.3% (95% confidence interval [CI], 64.7-72.0%), 39.0% (95% CI, 35.2 - 42.8%) and 86.7% (95% CI, 84.7 - 89.7%), respectively. Late adverse events were observed in 3 patients (1.6%) with Grade 3 liver dysfunction and in 3 patients (1.6%) with Grade 3 skin disorders, but there were no cases of Grade 4 or higher. Multivariate analysis of prognostic factors for overall survival revealed that mALBI grade in 2b(HR:3.13, 1.97-4.78, p<0.0001), tumor status in recurrent treatment (HR:1.50, 1.02-2.21, p = 0.039), the number of tumors in 2 or more (HR:2.16, 1.01-2.17, p = 0.045), and maximum tumor diameter in larger than 6 cm (HR:2.34, 1.50-3.61, p = 0.0001) were the predominant prognostic factors, while age, presence of vascular invasion, AFP and DCP were not. CONCLUSION The safety and efficacy of C-ion RT for bulky (≥4cm) locally advanced HCC was demonstrated. These results suggested that C-ion RT may be a new treatment option for locally advanced bulky HCC with no curative treatment options.

Abstract
Abstract
Background and study aims Endoscopic ultrasound-guided biliary drainage (EUS-BD) is a widely used alternative to endoscopic retrograde cholangiopancreatography (ERCP) when ERCP is unsuccessful or there are contraindications such as duodenal stenosis or postsurgical intestinal reconstruction. Therefore, we retrospectively investigated the therapeutic outcomes of EUS-BD in a medium-sized hospital.
Patients and methods We included 31 consecutive patients who underwent EUS-BD at the Kitasato University Medical Center between April 2018 and October 2021. Patient characteristics, technical and clinical success rates, stent patency, adverse events (AEs), and procedure time were analyzed.
Results Of the 31 patients included in this study, one underwent endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) and 30 underwent endoscopic ultrasound-guided hepaticoenterostomy (EUS-HES). The technical success rates were 100 % for EUS-CDS and 96.8 % for EUS-HES because EUS-HES was unsuccessful in one patient who then underwent EUS-CDS as an alternative treatment. The clinical success rates were 100 % for EUS-CDS and 96.7% for EUS-HES. The median follow-up period was 84 days (range: 14–483 days). Zero and 5 (16.6 %) patients who underwent EUS-CDS and EUS, respectively had stent dysfunction. The median stent patency (stent dysfunction and death) for EUS-HES was 124 days. AEs were observed in only two patients (6.7 %) who underwent EUS-HES.
Conclusions EUS-BD is now more widely used than before, and advances in the devices used have enabled the procedure to be performed more safely. Our results suggest that this introduction in medium-sized hospitals can be conducted safely.

Abstract
Objective This retrospective, single-center study assessed the effects of interferon (IFN)-free treatment of hepatitis C virus (HCV) infection, which has been approved for seven years; calculated the incidence of hepatocellular carcinoma (HCC) after achieving a sustained virologic response (SVR); and elucidated problems with follow-up for surveillance of post-SVR HCC, particularly the impact of the coronavirus disease 2019 (COVID-19) pandemic. Methods We summarized the SVR achievement rate of 286 HCV-infected patients who received 301 IFN-free treatments and analyzed the cumulative incidence of initial HCC and the cumulative continuation rate of follow-up after SVR in the 253 patients who achieved SVR and did not have a history of HCC. Results Among 286 patients who received IFN-free treatments, 14 dropped out, and the 272 remaining patients achieved an SVR after receiving up to third-line treatment. Post-SVR HCC occurred in 18 (7.1%) of the 253 patients without a history of HCC, with a cumulative incidence at 3 and 5 years after SVR of 6.6% and 10.0%, respectively; the incidence of cirrhosis at those time points was 18.2% and 24.6%, respectively.Of the 253 patients analyzed, 58 (22.9%) discontinued follow-up after SVR. Patients who had no experience with IFN-based therapy tended to drop out after SVR. Notably, the number of dropouts per month has increased since the start of the pandemic. Conclusion Currently, IFN-free treatment is showing great efficacy. However, the incidence of HCC after SVR should continue to be monitored. In this study, the COVID-19 pandemic did not affect treatment outcomes, but it may affect surveillance for post-SVR HCC.

Abstract
BACKGROUND AND AIM Endoscopic bilateral self-expandable metallic stent (SEMS) placement for unresectable malignant hilar biliary obstruction (MHBO) is widely performed; however, re-intervention after recurrent biliary obstruction (RBO) is often challenging. We compared stent-in-stent (SIS) and side-by-side (SBS) SEMS placement for MHBO considering re-intervention for RBO. METHODS One hundred five consecutive patients with MHBO who underwent endoscopic bilateral SEMS placement in our hospital and its affiliated institutions were enrolled in this study; 75 patients underwent partial SIS deployment between December 2005 and December 2012; and 30 underwent SBS deployment between January 2013 and March 2019. Initial treatments and re-interventions in each group were retrospectively evaluated. RESULTS Technical success rate (92% vs 100%, P = 0.179), procedure duration (46 vs 35 min, P = 0.382), functional success rate (97.1% vs 100%, P = 1.00), complication rate (24.6% vs 20.0%, P = 0.797), time to RBO (260 vs 312 days; Gray test, P = 0.815), and rate of RBO (59.4% vs 70.0%, P = 0.371) were not significantly different between the SIS and SBS groups. However, bilateral re-stenting with plastic stents through SEMS was successful in 63.4% of patients in the SIS group compared with 100% of patients in the SBS group (P = 0.0013). Median time to RBO upon first re-stenting with a plastic stent was 75 days (range, 11-195 days). CONCLUSIONS Endoscopic re-stenting after RBO was significantly more successful in the SBS group than in the SIS group. SBS method is suitable for MHBO considering revisionary stent placement.

Abstract
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is associated with complications such as post-ERCP pancreatitis (PEP). Protease inhibitors, including nafamostat mesylate (NM), have been evaluated for prophylaxis against PEP. AIM We describe the first multicenter randomized controlled trial assessing the prophylactic efficacy of NM against PEP. METHODS In this multicenter prospective study, we aimed to enroll 800 patients aged ≥ 20 years with a planned ERCP between December 2012 and March 2019. The primary outcome was the incidence and severity of PEP in patients who did not receive NM (non-NM) versus those who did (NM; 20 mg). Secondary outcomes included the incidence of PEP by NM initiation (pre- and post-ERCP), risk factors for PEP, and NM-related adverse events. RESULTS Only 441 of the planned 800 patients were enrolled (non-NM: n = 149; NM: n = 292 [pre-ERCP NM: n = 144; post-ERCP NM: n = 148]). Patient characteristics were balanced at baseline with no significant differences between groups. PEP occurred in 40/441 (9%) patients (non-NM: n = 15 [10%]; NM: n = 25 [9%]), including 17 (12%) and eight (8%) in the pre-ERCP and post-ERCP NM groups, respectively. In the NM group, the incidence of PEP was lower in the low-risk group than in the high-risk group. Pancreatic injection and double-guidewire technique were independent risk factors for PEP. NM-related adverse events of hyperkalemia occurred in two (0.7%) patients. CONCLUSIONS We found no evidence for the prophylactic effect of NM against PEP, regardless of the timing of administration; however, further studies are needed.

Abstract
Background Anti-programmed cell death protein 1 (PD-1) antibody monotherapy (PD1) has led to favorable responses in advanced non-acral cutaneous melanoma among Caucasian populations; however, recent studies suggest that this therapy has limited efficacy in mucosal melanoma (MCM). Thus, advanced MCM patients are candidates for PD1 plus anti-cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) combination therapy (PD1 + CTLA4). Data on the efficacy of immunotherapy in MCM, however, are limited. We aimed to compare the efficacies of PD1 and PD1 + CTLA4 in Japanese advanced MCM patients. Patients and methods We retrospectively assessed advanced MCM patients treated with PD1 or PD1 + CTLA4 at 24 Japanese institutions. Patient baseline characteristics, clinical responses (RECIST), progression-free survival (PFS), and overall survival (OS) were estimated using Kaplan–Meier analysis, and toxicity was assessed to estimate the efficacy and safety of PD1 and PD1 + CTLA4. Results Altogether, 329 patients with advanced MCM were included in this study. PD1 and PD1 + CTLA4 were used in 263 and 66 patients, respectively. Baseline characteristics were similar between both treatment groups, except for age (median age 71 versus 65 years; P < 0.001). No significant differences were observed between the PD1 and PD1 + CTLA4 groups with respect to objective response rate (26% versus 29%; P = 0.26) or PFS and OS (median PFS 5.9 months versus 6.8 months; P = 0.55, median OS 20.4 months versus 20.1 months; P = 0.55). Cox multivariate survival analysis revealed that PD1 + CTLA4 did not prolong PFS and OS (PFS: hazard ratio 0.83, 95% confidence interval 0.58-1.19, P = 0.30; OS: HR 0.89, 95% confidence interval 0.57-1.38, P = 0.59). The rate of ≥grade 3 immune-related adverse events was higher in the PD1 + CTLA4 group than in the PD1 group (53% versus 17%; P < 0.001). Conclusions First-line PD1 + CTLA4 demonstrated comparable clinical efficacy to PD1 in Japanese MCM patients, but with a higher rate of immune-related adverse events. Anti-PD-1 plus anti-CTLA-4 antibody therapy (PD1 + CTLA4) is an option for patients with advanced mucosal melanoma (MCM). Data on the efficacy of PD1 + CTLA4 compared with PD-1 monotherapy (PD1) for MCM, however, are limited. We retrospectively analyzed data from 329 Japanese patients with advanced MCM treated with PD1 or PD1 + CTLA4. No significant differences in objective response rate, progression-free survival, or overall survival were observed. Immune-related adverse events resulting in treatment cessation were higher in the PD1 + CTLA4 group.

Abstract
We herein report the first case of metastatic pancreatic leiomyosarcoma derived from the urinary bladder diagnosed by an endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) in a 65-year-old woman. The patient had undergone total cystectomy for bladder leiomyosarcoma. Four years thereafter, a nodule was observed in her left lung on chest computed tomography. Suspecting primary lung cancer, pulmonologists at our hospital recommended a thoracoscopic lung biopsy, which the patient refused. Five years post-cystectomy, fluorodeoxyglucose positron emission tomography revealed enlargement of the left lung nodule and a new mass in the pancreatic head. She was referred to our department for the pathological diagnosis of a pancreatic head mass by an EUS-FNB. The EUS-FNB yielded adequate pancreatic tissue for an immunohistochemical analysis. A diagnosis of metastatic pancreatic lesion originating from the urinary bladder was made. In atypical pancreatic tumors, the utilization of an EUS-FNB and immunohistochemical analysis can help establish an accurate diagnosis.

Abstract
BACKGROUND Information on whether a fine-needle biopsy (FNB) needle can improve histopathological specimen quality or the amount of core tissue collected in the diagnosis of subepithelial lesions (SELs) remains insufficient. In this study, we aimed to compare the procedure outcomes and adequacy of histopathological specimens of fine-needle aspiration (FNA) and FNB needles in endoscopic ultrasound-guided tissue acquisition (EUS-TA) using sample isolation processing by stereomicroscopy (SIPS) in patients with SELs. METHODS We performed a retrospective comparison of SEL cases registered in two previously conducted prospective studies. Of 61 cases, we identified 56 cases of SELs that involved the muscularis propria layer. Of these, 27 patients who underwent EUS-TA using a 22-gauge FNA needle between July 2016 and December 2017, and 29 patients who underwent the procedure using a 22-gauge FNB needle between March 2018 and January 2019 were included in the FNA and FNB group, respectively. RESULTS Patient background characteristics did not differ between the groups. The technical success rate was 100% in both groups. The median adequacy score was significantly higher in the FNB group than in the FNA group (P < .01). The histological diagnosis showed no significant difference in the accuracy rate between the groups. CONCLUSIONS In EUS-TA using the SIPS procedure to target SELs derived from the muscularis propria layer, FNB needles collect more core tissues and significantly improve histopathological specimen quality compared with FNA needles. When combined with SIPS, a high tissue diagnosis rate may be obtained regardless of the type of puncture needle used.

Abstract
Background and Objectives: Balloon enteroscopy-assisted ERCP (BE-ERCP) has become the first-line therapy for biliopancreatic anastomotic strictures. However, it is not always successful, and salvage methods have not been established. This study aimed to evaluate the outcomes of EUS-guided transanastomotic drainage using a forward-viewing (FV) echoendoscope. Patients and Methods: Of eight cases wherein BE-ERCP treatment failed due to severe or complete benign anastomotic stricture, seven cases underwent EUS-guided choledochojejunostomy, and EUS-guided pancreaticojejunostomy was applied in one case after intubating an FV echoendoscope into the anastomotic site. Results: The success rate of reaching the target site was 100% (8/8) for patients after modified Child resection. The median time to reach the anastomosis was 5 min (range: 3–17 min), and the technical success rate for drainage was 75% (6/8). The median total procedure time was 33.5 min (range: 22–45 min) for six successful cases. Cautery dilatation catheters were necessary to dilate the puncture site in all cases, and no early complications were observed. During the follow-up period (median: 13.3 months [range: 6.5–60.3]), recurrence of the stricture occurred in one case, and a stent-free status was achieved after 6–12 months of stent placement in five cases. Conclusions: EUS-guided transanastomotic drainage using an FV echoendoscope is a feasible and safe rescue technique for the management of benign severe biliopancreatic anastomotic strictures.

Abstract
Background/Aims Cholecystitis can occur after the placement of covered self-expandable metallic stents for distal malignant biliary obstructions. We aimed to identify risk factors for cholecystitis following covered self-expandable metallic stent placement.
Methods We investigated risk factors related to cholecystitis following covered self-expandable metallic stent placement in 118 patients with distal malignant biliary obstructions between January 1, 2015 and April 30, 2019. Endoscopic assessments and tumor invasion to the arteries feeding the gallbladder were determined by a pancreaticobiliary endoscopist and a radiologist, respectively.
Results The median patient age was 72 years (men, 61.0%). The flow of the contrast agent into the gallbladder and tumor involvement in the orifice of the cystic duct were observed in 35 (29.7%) and 35 (29.7%) patients, respectively. During the observation period (median, 179 days), cholecystitis occurred in 18 (15.3%) patients. Multivariate analysis revealed the flow of the contrast agent into the gallbladder (p=0.023) and tumor involvement in the orifice of the cystic duct (p=0.005) as significant independent risk factors associated with cholecystitis.
Conclusions The flow of the contrast agent into the gallbladder and tumor involvement in the orifice of the cystic duct are potential independent risk factors for cholecystitis following the placement of covered self-expandable metallic stents. A follow-up prospective study is warranted to validate their influence.

Abstract
Abstract
Introduction
Mediastinal radiation can lead to long-term cardiac sequelae, including aortic valve disease. Surgical aortic valve replacement (SAVR) is associated with poor outcomes in this population. Transcatheter aortic valve replacement (TAVR) now provides an alternative treatment strategy that may improve outcomes.
Purpose
To compare 30-day outcomes after TAVR vs. isolated SAVR for radiation-associated severe symptomatic aortic stenosis using the Society of Thoracic Surgery (STS) National Adult Cardiac Surgery Database.
Methods
We evaluated 1,668 TAVR and 2,611 isolated SAVR patients enrolled in the STS national database from July 2011 through December 2018. A propensity score for TAVR vs. SAVR was derived using a non-parsimonious logistic regression model that included 29 pre-operative variables and was used to generate a 1:1 matched cohort (NTotal=1,560). 30-day outcomes in TAVR vs. SAVR patients were compared in the matched cohort using conditional logistic regression. We also tested for temporal trends in 30-day mortality separately for TAVR and SAVR in the matched cohort, adjusted for potential confounders, to see if outcomes varied across the study period.
Results
In the propensity-matched cohort, baseline demographics, comorbidities and preoperative characteristics were balanced between the TAVR and SAVR groups. The mean age was 73.3 years and 75% were females in each group. In the propensity-matched cohort, TAVR was associated with significantly reduced 30-day all-cause [OR=0.50 (0.30–0.84), p=0.01] and cardiovascular mortality as compared to SAVR [OR=0.33 (0.14–0.78), p=0.01]. Similarly, post-operative complications occurred less in the TAVR group except for stroke/transient ischemic attack (TIA) [OR=3.17 (1.27–7.93), p=0.01] and pacemaker implantation [OR=1.71 (1.21–2.44), p=0.003] which were significantly higher with TAVR (Figure 1A). While, 30-day mortality associated with both procedures improved over the course of the study, the trend was only statistically significant in the TAVR group following adjustment for potential confounders. TAVR was consistently associated with better survival than SAVR in the matched cohort across the study period (Figure 1B).
Conclusion
Our findings suggest that TAVR is a safe alternative to SAVR for radiation-associated severe symptomatic aortic stenosis and is associated with lower 30-day mortality and post-operative complications. The risk of stroke/TIA and pacemaker implantation is higher with TAVR and should be considered when choosing therapy. Additional prospective studies to validate our findings and evaluate long-term outcomes are needed to further guide clinical decision making in this population.

Abstract
Interleukin-1β (IL-1β) is an inflammatory cytokine produced by monocytes/macrophages and is closely associated with periodontal diseases. The NLRP3 inflammasome is involved in IL-1β activation through pro-IL-1β processing and pyroptotic cell death in bacterial infection. Recently, glyburide, a hypoglycemic sulfonylurea, has been reported to reduce IL-1β activation by suppressing activation of the NLRP3 inflammasome. Therefore, we evaluated the possibility of targeting the NLRP3 inflammasome pathway by glyburide to suppress periodontal pathogen-induced inflammation. THP-1 cells (a human monocyte cell line) were differentiated to macrophage-like cells by treatment with phorbol 12-myristate 13-acetate and stimulated by periodontopathic bacteria, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, or Fusobacterium nucleatum, in the presence of glyburide. IL-1β and caspase-1 expression in the cells and culture supernatants were analyzed by Western blotting and enzyme-linked immunosorbent assay, and cell death was analyzed by lactate dehydrogenase assay. Stimulation of THP-1 macrophage-like cells with every periodontopathic bacteria induced IL-1β secretion without cell death, which was suppressed by the NLRP3 inhibitor, MCC950, and caspase-1 inhibitor, z-YVAD-FMK. Glyburide treatment suppressed IL-1β expression in culture supernatants and enhanced intracellular IL-1β expression, suggesting that glyburide may have inhibited IL-1β secretion. Subsequently, a periodontitis rat model was generated by injecting periodontal bacteria into the gingiva, which was analyzed histologically. Oral administration of glyburide significantly suppressed the infiltration of inflammatory cells and the number of osteoclasts in the alveolar bone compared with the control. In addition to glyburide, glimepiride was shown to suppress the release of IL-1β from THP-1 macrophage-like cells, whereas other sulfonylureas (tolbutamide and gliclazide) or other hypoglycemic drugs belonging to the biguanide family, such as metformin, failed to suppress IL-1β release. Our results suggest that pharmacological targeting of the NLRP3 pathway may be a strategy for suppressing periodontal diseases.

Abstract
The objectives of this study were to evaluate survival in 141 patients with stage II-IV oral squamous cell carcinoma (OSCC) treated with preoperative intra-arterial chemotherapy with docetaxel, cisplatin, and peplomycin combined with intravenous chemotherapy using 5-fluorouracil (IADCPIVF) via the superficial temporal artery, and to clarify the prognostic factors. The study population included 59 patients with stage II OSCC, 34 with stage III, and 48 with stage IV. After IADCPIVF, 139 patients underwent surgery; minimally invasive surgeries (MIS) including excisional biopsy were performed on 96 patients with a remarkably good response to IADCPIVF. The primary tumour response rate was 99.3% (complete response rate 56.7%, good partial response rate 17.0%, fair partial response rate 25.5%). Additionally, there were no serious adverse events associated with IADCPIVF. The 5-year overall survival rate was 74.6% (stage II 83.6%, stage III 72.7%, stage IV 64.8%). In the multivariate analysis of survival, T classification and clinical tumour response were significant prognostic factors. Eight (8.3%) of the patients who received MIS had primary recurrence and six were salvaged. In conclusion, IADCPIVF is safe and efficacious for treating OSCC, and MIS could reduce the extent of primary tumour resection in the case of a remarkably good response.

Abstract
BACKGROUND Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is new onset acute pancreatitis after ERCP. This complication is sometimes fatal. As such, PEP should be diagnosed early so that therapeutic interventions can be carried out. Serum lipase (s-Lip) is useful for diagnosing acute pancreatitis. However, its usefulness for diagnosing PEP has not been sufficiently investigated.
AIM This study aimed to retrospectively examine the usefulness of s-Lip for the early diagnosis of PEP.
METHODS We retrospectively examined 4192 patients who underwent ERCP at our two hospitals over the last 5 years. The primary outcomes were a comparison of the areas under the receiver operating characteristic (ROC) curves (AUCs) of s-Lip and serum amylase (s-Amy), s-Lip and s-Amy cutoff values based on the presence or absence of PEP in the early stage after ERCP via ROC curves, and the diagnostic properties [sensitivities, specificities, positive predictive values (PPV), and negative predictive value (NPV)] of these cutoff values for PEP diagnosis.
RESULTS Based on the eligibility and exclusion criteria, 804 cases were registered. Over the entire course, PEP occurred in 78 patients (9.7%). It occurred in the early stage after ERCP in 40 patients (51.3%) and in the late stage after ERCP in 38 patients (48.7%). The AUCs were 0.908 for s-Lip [95% confidence interval (CI): 0.880-0.940, P < 0.001] and 0.880 for s-Amy (95%CI: 0.846-0.915, P < 0.001), indicating both are useful for early diagnosis. By comparing the AUCs, s-Lip was found to be significantly more useful for the early diagnosis of PEP than s-Amy (P = 0.023). The optimal cutoff values calculated from the ROC curves were 342 U/L for s-Lip (sensitivity, 0.859; specificity, 0.867; PPV, 0.405; NPV, 0.981) and 171 U/L for s-Amy (sensitivity, 0.859; specificity, 0.763; PPV, 0.277; NPV, 0.979).
CONCLUSION S-Lip was significantly more useful for the early diagnosis of PEP. Measuring s-Lip after ERCP could help diagnose PEP earlier; hence, therapeutic interventions can be provided earlier.

Abstract
BACKGROUND The efficacy and safety of nanoparticle albumin-bound paclitaxel (nab-PTX) plus gemcitabine (GEM) in elderly Japanese patients with pancreatic cancer remain unclear. Therefore, we prospectively investigated the tolerability and efficacy of nab-PTX + GEM in Japanese patients aged ≥ 75 years with non-curatively resectable pancreatic cancer. METHODS We treated eligible patients (n = 27) with nab-PTX + GEM until disease progression, appearance of adverse events, or withdrawal of consent. The primary endpoints included adverse events as well as dosing- and survival-related parameters. RESULTS The rates of 2-cycle completion were 48.1% for nab-PTX and 55.6% for GEM; the relative dose intensities for the 7th (median) treatment cycle were 65.1% and 74.1%, respectively, whereas the dose-reduction rates were 81.5% and 48.1%, respectively. Grade 3 or higher hemotoxicity was observed in 14 of 27 subjects (51.9%); moreover, 22% experienced grade ≥ 3 peripheral nerve disorder and 1 patient (3.7%) died owing to chemotherapy-related interstitial pneumonia. The disease control rate was 92.6% (25/27), while the median progression-free and overall survival times were 7 and 10.3 months, respectively. CONCLUSION The nab-PTX + GEM regimen is as efficacious in elderly patients who meet certain criteria as it is in previously reported non-elderly patients. The regimen is feasible with appropriate dose adjustments and attention to adverse events. TRIAL REGISTRATION Clinical trial registration number: UMIN000018907.

Abstract
The patient was a 69-year-old female with a chief complaint of yellow staining of her urine. A detailed physical examination and laboratory tests were carried out, and as a result, her condition was diagnosed as unresectable advanced extrahepatic cholangiocarcinoma with liver metastases. Chemotherapy using gemcitabine + cisplatin was initiated, and computed tomography after six cycles revealed that the liver metastases had disappeared, and that a partial response was achieved in the primary tumor. After tan cycles, a pylorus-preserving pancreaticoduodenectomy was performed as conversion surgery, and as a result, a pathological complete response was achieved in the primary tumor. After the primary lesion was resected, we were able to start an adjuvant chemotherapy immediately. Approximately 19 months have passed since the surgery, and the patient is currently alive and recurrence-free. If an improvement of the outcomes of chemotherapy in unresectable advanced biliary tract carcinomas is achieved in the future, there could be an increase in the number of treatment-responsive cases like the one reported in this study. Accumulating a large number of cases successfully treated by conversion surgery, and conducting a detailed analysis of the postoperative course, may help design adequate treatment strategies.

Abstract
AIMS Patellofemoral problems are a common complication of total knee arthroplasty. A high compressive force across the patellofemoral joint may affect patient-reported outcome. However, the relationship between patient-reported outcome and the intraoperative patellofemoral contact force has not been investigated. The purpose of this study was to determine whether or not a high intraoperative patellofemoral compressive force affects patient-reported outcome. PATIENTS AND METHODS This prospective study included 42 patients (42 knees) with varus-type osteoarthritis who underwent a bi-cruciate stabilized total knee arthroplasty and in whom the planned alignment was confirmed on 3D CT. Of the 42 patients, 36 were women and six were men. Their mean age was 72.3 years (61 to 87) and their mean body mass index (BMI) was 24.4 kg/m 2 (18.2 to 34.3). After implantation of the femoral and tibial components, the compressive force across the patellofemoral joint was measured at 10°, 30°, 60°, 90°, 120°, and 140° of flexion using a load cell (Kyowa Electronic Instruments Co., Ltd., Tokyo, Japan) manufactured in the same shape as the patellar implant. Multiple regression analyses were conducted to investigate the relationship between intraoperative patellofemoral compressive force and patient-reported outcome two years after implantation. RESULTS No patient had anterior knee pain after total knee arthroplasty. The compressive force across the patellofemoral joint at 140°of flexion was negatively correlated with patient satisfaction (R 2 = 0.458; β = -0.706; p = 0. 041) and Forgotten Joint Score-12 (FJS-12; R 2 = .378; β = -0.636; p = 0. 036). The compressive force across the patellofemoral joint at 60° of flexion was negatively correlated with the patella score (R 2 = 0.417; β = -0.688; p = 0. 046). CONCLUSION Patient satisfaction, FJS-12, and patella score were affected by the patellofemoral compressive force at 60° and 140° of flexion. Reduction of the patellofemoral compressive forces at 60° and 140° of flexion angle during total knee arthroplasty may improve patient-reported outcome, but has no effect on anterior knee pain.

Abstract
AIM To assess M1/M2 macrophage phenotypes in a coronal pulp regeneration model in rats, under the hypothesis that there are dynamic M1/M2 phenotype changes during the different stages of the pulp regeneration. METHODOLOGY The maxillary first molars of Wistar rats were pulpotomized, and biodegradable hydrogel-made scaffolds carrying rat bone marrow mesenchymal stem cells were implanted in the pulp chamber. After 3, 7 and 14 days, samples were processed for (i) histological analysis and double immunoperoxidase staining for CD68 (a general macrophage marker) and one of either CCR7 (an M1 marker), CD163 (an M2 marker) or CD206 (an M2 marker); (ii) real-time PCR for AIF1 (an M1 marker), CD163, CD206, IL-10 and TNF-α mRNA expression; and (iii) Western blotting for the detection of CD68, CCR7 and CD206 proteins. RESULTS Histological analysis of the implanted region revealed sparse cellular distribution at 3 days, pulp-like tissue with a thin dentine bridge-like structure at 7 days, and dentine bridge-like mineralized tissue formation and resorption of most scaffolds at 14 days. CCR7+ macrophages had the highest density at 3 days, and then significantly decreased until 14 days (P < 0.05). In contrast, M2 marker (CD163 or CD206) expressing macrophages had the lowest density at 3 days and significantly increased until 14 days (P < 0.05). AIF1 and TNF-α mRNA levels, and CD68 and CCR7 protein levels were highest at 3 days. CD163 and CD206 mRNA levels, and CD206 protein levels increased with time and showed the highest at 14 days. IL-10 mRNA was highest at 3 days, decreased at 7 days and increased at 14 days. CONCLUSIONS Macrophages in the regenerating pulp tissue underwent a distinct transition from M1-dominant to M2-dominant, suggesting that the M1-to-M2 transition of macrophages plays an important role in creating a favourable microenvironment necessary for pulp tissue regeneration.

Abstract
Polymers, derived from bio-derived resources, have gained considerable momentum because of a lower dependence over conventional fossil-based resources without compromising the materials' thermo-mechanical properties. Unique characteristics of organic and inorganic materials can be incorporated by a combination of both to obtain hybrid materials. We have recently developed a series of transparent biopolyimides (BPI) from a biologically derived exotic amino acid, 4-aminocinnamic acid (4ACA) to yield 4-amino truxillic ester (4ATA ester) derivatives. In the present research, the polyimide-precursor was subjected to sol–gel polycondensation reactions with silicon-alkoxide followed by annealing under vacuo to yield a biopolyimide-silica hybrid. The biopolyimide structures (4ATA acid/ester) and their silica hybrids thermo-mechanical, electrical and optical performance were evaluated. It was found that the biopolyimide with 4ATA(ester) yields thermo-mechanically robust films with very high electrical stability as well as optical transparency, plausibly due to the uniform dispersion of the silica particles in the biopolyimide matrix. Biopolyamide structure and their silica hybrids performances were studied. Biopolyamide with inability to interact with silanol during sol–gel condensation for silica formation showed superior thermo-mechanical, optical and electrical properties.![]()

Abstract
BACKGROUND AND AIM Preoperative cholangitis after preoperative drainage has been reported to increase postoperative complications, particularly pancreatic fistula. We therefore examined the effects of cholangitis after preoperative endoscopic biliary drainage (EBD) on postoperative pancreatic fistula in patients with middle and lower malignant biliary strictures. METHODS The study group comprised 102 patients who underwent EBD among patients who underwent surgery. RESULTS Of the 102 patients, 33 (32%) had postoperative pancreatic fistulas, and 56 (55%) had preoperative cholangitis after preoperative drainage. Analysis of risk factors for preoperative cholangitis showed that a total bilirubin level of 2.9 mg/dL or higher (hazard ratio [HR], 2.95; 95% confidence interval [CI], 1.223-7.130; P = 0.016) and a surgical waiting time of 29 days or longer (HR, 4.23; 95% CI, 1.681-10.637; P = 0.02) were independent risk factors for cholangitis. Patients with preoperative cholangitis had a significantly higher incidence of pancreatic fistula than did patients without preoperative cholangitis (78.8 vs 21.2%; P = 0.001). Patients with biliary cancer had a significantly higher incidence of pancreatic fistula than did those with pancreatic cancer (72.7 vs 27.2%; P = 0.005). Multivariate analysis showed that preoperative cholangitis (HR, 4.8; 95% CI, 1.785-12.992; P = 0.001) and biliary cancer (HR, 3.5; 95% CI, 1.335-8.942; P = 0.006) were significant independent risk factors for postoperative pancreatic fistula. CONCLUSION Prevention of preoperative cholangitis, a risk factor for postoperative pancreatic fistula, is likely to decrease the incidence of postoperative pancreatic fistula.

Abstract
Inhalation burn injury (IBI) is a risk factor for mortality in burn patients. However, it is difficult to diagnose IBI using traditional physical examination alone, especially in prehospital settings. Therefore, facial burn patients are usually treated for suspected IBI. In the present study, we investigated whether fire site information could predict IBI as an alternative to traditional physical examination. This retrospective single-centre analysis involved 27 facial burn patients with suspected IBI who were admitted between 2014 and 2016. The patients were divided into two groups (IBI and non-IBI) according to bronchoscopy findings. Fire site information was compared between the two groups. The IBI (n = 13) and non-IBI (n = 14) groups were compared. Domestic fire was more frequent in the IBI group (69% vs. 29%, P = 0.035). The IBI group included one patient with carboxyhemoglobin ≥10% on admission. Prehospitalization fire site information, particularly domestic fires, might predict IBI in facial burn patients..

Abstract
AIM The purpose of this study is to compare the diagnostic yield of endoscopic ultrasound (EUS)-guided fine-needle aspiration (EUS-FNA) and EUS-guided fine-needle biopsy (EUS-FNB) for gastric subepithelial tumors (SET). METHODS Patients diagnosed SET derived from fourth layer of the stomach were prospectively enrolled and randomly assigned to undergo both EUS-FNA using standard needle and EUS-FNB using a core biopsy needle alternatively to the same lesion a total of four times per session. The specimen was carefully examined for the presence of a macroscopic visible core, appearing as threadlike yellowish or bloody pieces of tissue and blinded histocytologic analyses were conducted. For spindle cell lesions by hematoxylin and eosin staining (H&E) on histologic evaluation, immunohistochemical staining was performed in all cases to confirm the pathological diagnosis. RESULTS A total of 23 patients were enrolled and underwent paired EUS-FNA and -FNB sampling. The diagnostic rate due to immunohistochemical staining was 73.9% and 91.3%, respectively (P = .120). The rate of obtaining specimens with a macroscopic yellowish core and only a bloody core among the tissue specimens were respectively 43.5% and 52.2% for EUS-FNA and 69.6% and 30.4% for EUS-FNB. The diagnostic rate for a yellowish core (84.6%) and a bloody core (84.2%, P = .971) did not differ significantly. CONCLUSION Both techniques were equivalently safe and successful in terms of a high diagnostic yield for gastric SET. And the tissue that can be immunohistochemically stained is present even in the specimens that appear to be a macroscopically bloody core.

Abstract
BACKGROUND AND OBJECTIVE Dental calculus is a mineralized deposit attached to the tooth surface. We have shown that cellular uptake of dental calculus triggers nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome activation, leading to the processing of the interleukin-1β precursor into its mature form in mouse and human phagocytes. The activation of the NLRP3 inflammasome also induced a lytic form of programmed cell death, pyroptosis, in these cells. However, the effects of dental calculus on other cell types in periodontal tissue have not been investigated. The aim of this study was to determine whether dental calculus can induce cell death in oral epithelial cells. MATERIAL AND METHODS HSC-2 human oral squamous carcinoma cells, HOMK107 human primary oral epithelial cells and immortalized mouse macrophages were exposed to dental calculus or 1 of its components, hydroxyapatite crystals. For inhibition assays, the cells were exposed to dental calculus in the presence or absence of cytochalasin D (endocytosis inhibitor), z-YVAD-fmk (caspase-1 inhibitor) or glyburide (NLRP3 inflammasome inhibitor). Cytotoxicity was determined by measuring lactate dehydrogenase (LDH) release and staining with propidium iodide. Tumor necrosis factor-α production was quantified by enzyme-linked immunosorbent assay. Oral epithelial barrier function was examined by permeability assay. RESULTS Dental calculus induced cell death in HSC-2 cells, as judged by LDH release and propidium iodide staining. Dental calculus also induced LDH release from HOMK107 cells. Following heat treatment, dental calculus lost its capacity to induce tumor necrosis factor-α in mouse macrophages, but could induce LDH release in HSC-2 cells, indicating a major role of inorganic components in cell death. Hydroxyapatite crystals also induced cell death in both HSC-2 and HOMK107 cells, as judged by LDH release, indicating the capacity of crystal particles to induce cell death. Cell death induced by dental calculus was significantly inhibited by cytochalasin D, z-YVAD-fmk and glyburide, indicating NLRP3 inflammasome involvement. In permeability assays, dental calculus attenuated the barrier function of HSC-2 cell monolayers. CONCLUSION Dental calculus induces pyroptotic cell death in human oral epithelial cells and the crystalline structure plays a major role in this process. Oral epithelial cell death induced by dental calculus might be important for the etiology of periodontitis.
