Abstract
AIM The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the allocation of medical resources, including cancer screening, diagnosis, and treatment. We aimed to investigate the effects of the pandemic on morbidity and mortality following hepatectomy for hepatocellular carcinoma (HCC). METHODS We identified patients who underwent hepatectomy for HCC between 2018 and 2021 from the Japanese National Clinical Database (NCD). The number of surgical cases, the use of intensive care units, and the incidence of morbidity were assessed. The standardized morbidity / mortality ratio (SMR) was used to evaluate the rates of morbidity (bile leakage and pneumonia) and mortality in each month, which compares the observed incidence to the expected incidence calculated by the NCD's risk calculator. RESULTS The study included a total of 10 647 cases. The number of patients undergoing hepatectomy for HCC gradually decreased. The proportion of patients aged 80 years or older increased and that of cases with T1 stage decreased. The proportion of patients who were admitted to the intensive care unit did not change between the pre- and postpandemic period. The mean actual incidence rates of bile leakage, pneumonia, 30-day mortality, and surgical mortality were 9.2%, 2.3%, 1.4%, and 2.1%, respectively. The SMR for the mortalities and morbidities in each month did not increase mostly throughout the COVID-19 pandemic. CONCLUSIONS The present study showed the decreasing number of resected cases for HCC, while the surgical safety for hepatectomy was enough to be maintained by managing medical resources in Japan.

Abstract
Aim Neoadjuvant chemoradiotherapy may improve survival in patients with advanced cholangiocarcinoma. This Phase I study aimed to determine the recommended dose of neoadjuvant chemoradiotherapy and decide whether to move to a Phase II study. Methods Patients diagnosed with resectable stage II-IVa cholangiocarcinoma were administered cisplatin (40 [level 0], 50 [level 1 as starting dose], or 60 [level 2] mg/m2), 80 mg/m2 of S-1, and 50.4 Gy of external beam radiation. The recommended dose was defined as a dose one-step lower than the maximum-tolerated dose, which was defined when dose-limiting toxicity was observed in three or more of the six patients. Results Twelve patients were eligible from November 2012 to May 2016. Ten patients had perihilar cholangiocarcinoma and two patients had distal cholangiocarcinoma. Dose-limiting toxicity was observed in one of the first six patients at level 1 and two of the next six patients at level 2; thus, the maximum-tolerated dose was not determined even at level 2 and the recommended dose was determined as level 2. Four patients had partial response, four patients had stable disease, and two patients had progression of disease because of liver metastases. Finally, nine patients underwent radical surgery and seven cases achieved R0 resection. However, five cases suffered biliary leakage and one suffered intrahospital death due to rupture of the hepatic artery. Conclusion We determined the recommended dose of neoadjuvant chemoradiotherapy for resectable cholangiocarcinoma. However, we terminated the trial due to a high incidence of morbidity and unexpected mortality.

Abstract
Aim Liver allografts from brain-dead donors, which were declined and were eventually not transplanted due to accompanying marginal factors, have never been surveyed in Japan. We surveyed the declined allografts and discussed the graft potential focusing on various marginal factors. Methods We collected data on brain-dead donors between 1999 and 2019 from the Japan Organ Transplant Network. We divided their liver allografts into declined (nontransplanted) and transplanted ones, and then characterized declined ones focusing on their timepoints of decline and accompanying marginal factors. For each marginal factor, we calculated the decline rate from the number of declined and transplanted allografts, and assessed the 1-year graft survival rate from transplanted allografts. Results A total of 571 liver allografts were divided into 84 (14.7%) declined and 487 (85.3%) transplanted ones. In the declined allografts, a majority was declined after laparotomy (n = 55, 65.5%), most of which had steatosis and/or fibrosis (n = 52). Out of the moderate steatotic (without F ≥ 2 fibrosis) allografts (n = 33), 21 were declined and 12 were transplanted, leading to a 63.6% decline rate. The latter 12 achieved a 92.9% 1-year graft survival rate after transplantation. Comparison of donor background showed no significant difference between the declined and transplanted allografts. Conclusion Pathological abnormalities of steatosis/fibrosis seem to be the most common donor factor leading to graft decline in Japan. Allografts with moderate steatosis were highly declined; however, transplanted ones achieved promising outcomes. This national survey highlights the potential utility of liver allografts with moderate steatosis.

Abstract
Abstract
Study question
This study was to investigate effect of SERa on the fertilization rate, embryonic development after ICSI, and clinical and perinatal outcomes after single blastocyst transfer.
Summary answer
SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.
What is known already
Based on findings that the risk of congenital abnormalities in the newborn is higher in ovum with SERa in the cytoplasm, the Istanbul consensus workshop at the 2011 meeting of the ESHRE recommended against fertilizing ovum with SERa due to these risks. However, there have been several reports of healthy infants born from embryos derived from SERa, suggesting that, while more long-term follow-up is necessary, healthy births are possible from such embryos. In 2017, the 2011 recommendations were reviewed in the Alpha/ESHRE consensus (Vienna), which said the approach should be determined on a case-by-case basis.
Study design, size, duration
We retrospectively investigated 23,007 oocytes which was retrieved between January 2016 and March 2020. Of these, 1,038 oocytes (4.5%) with visible SERa comprised SERa (+), while 21,969 oocytes (95.5%) without SERa comprised SERa (-).
Participants/materials, setting, methods
SERa were observed under the microscopy after denudation. The rate of fertilization, good-quality day-3 embryos, good-quality day-5 blastocysts, and day-5, 6 or 7 blastocysts were evaluated for both groups. We also compared the rate of clinical pregnancy, live birth, miscarriage, and birth defects in single blastocyst transfer between SERa (+) derived 114 blastocysts and SERa (-) derived 6,290 blastocysts from January 2016 and December 2018.
Main results and the role of chance
The results are shown. 2PN fertilization rate outcomes after ICSI (SERa(-) eggs vs. SERa(+)eggs),81.4%(17,873/21,969) vs.79.4% (823/1,038),and good-quality day3 rate was 61.1%(10,927/17,873)vs.60.9% (501/823) which was not significantly different. Good-quality day5 blastocyst rate was 46.5% (7,876/16,955) vs. 39.8%(304/763), and day 5 blastocyst success rate was 60.8% (10,317/16,955) vs.54.3% (414/763), which were both significantly lower with SERa(+). (P < 0.001) The day 6 blastocyst success rate was 69.9% (11,849/16,955) vs. 65.5% (500/763) (P = 0.01), and the day 7 blastocyst success rate was 70.9% (12,024/16,955) vs. 67.5% (515/763) (P = 0.04), which were all significantly lower with SERa(+).The clinical pregnancy rate was 39.4% (2,481/6,290) vs. 35.1% (40/114), the live birth rate was 27.7% (1,745/6,290) vs. 26.3% (30/114), and the miscarriage rate was 27.5% (683/2,481) vs. 20.0% (8/40) and the congenital abnormality rate was 1.6% (29/1,757) vs. 0% (0/30) for SERa(-) embryos and SERa(+) embryos, respectively, which were not significantly different. Blastocyst derived from oocytes with SERa has similar clinical and perinatal outcomes with those of oocytes without SERa. Significant differences were examined using the chi-squared test, with p < 0.05, indicating a significant difference.
Limitations, reasons for caution
Embryos derived SERa (+) were transferred when the patient did not want any more oocytes retrievals, no embryos derived SERa (-) were available, and only if the couple desired embryo transfer after the problems associated with SERa (+) embryos were fully explained.
Wider implications of the findings
To the best of our knowledge, this study is the largest number of live births investigating the outcome of SERa (+) derived embryos. SERa (+) derived embryo can be selected as embryos for transfer when no available SERa (-) derived embryos.

Abstract
The preceding propagation of turbulence pulses has been observed for the first time in heat avalanche events during the collapse of the electron internal transport barrier (e-ITB) in the Large Helical Device. The turbulence and heat pulses are generated near the foot of the e-ITB and propagate to the peripheral region within a much shorter time than the diffusion timescale. The propagation speed of the turbulence pulse is approximately 10 km/s, which is faster than that of the heat pulse propagating at a speed of 1.5 km/s. The heat pulse propagates at approximately the same speed as that in the theoretical prediction, whereas the turbulence pulse propagates one order of magnitude faster than that in the prediction, thereby providing important insights into the physics of non-local transport.

Abstract
Aim Using nationwide data collected over the past 20 years, we aimed to investigate deceased donor liver transplantation (DDLT) outcomes to develop a unique risk model that can be used to establish a standard for organ acceptance in Japan. Methods Data were collected for 449 recipients aged ≥18 years who underwent DDLT between 1999 and 2019. Least absolute shrinkage and selection operator (LASSO) regression analysis was utilized to develop an original risk score model for 1‐year graft loss (termed the Japan Risk Index [JRI]). We developed risk indices according to recipient, donor, and surgery components (termed JRI‐R, D, and S, respectively). The JRI was validated via a 5‐fold cross‐validation. We also compared DDLT outcomes and risk indices among Era1 (−2011), Era2 (−2015), and Era3 (−2019). Results The 1‐year graft survival rate was 89.5% and improved significantly, reaching 84.7%, 87.6%, and 93.9% in Era1, Era2, and Era3, respectively. The JRI was calculated as JRI‐R (re‐transplantation, Model for End‐Stage Liver Disease score, medical condition in intensive care unit) × JRI‐D (age, catecholamine index, maximum sodium, maximum total bilirubin) × JRI‐S (total ischemic time) × 0.84. The risk model achieved a mean C‐statistic value of 0.81 in the validation analysis. The risk index was significantly lower in Era3 than in Era2. Conclusion Changes in the risk index over time indicated that avoiding risks contributed to the improved outcomes in Era3. The JRI is unique to adult DDLT in Japan and may be useful as a reference for organ acceptance in the future.

Abstract
Background Gallbladder cancer (GBC) with liver metastasis is considered unresectable. However, there have been infrequent reports of long-term survival in patients with GBC and liver metastases. Therefore, we examined the characteristics of long-term survivors of gallbladder cancer with liver metastasis. Methods A retrospective multicenter study of 462 patients with GBC (mean age, 71 years; female, 51%) was performed. Although patients with pre-operatively diagnosed GBC and liver metastasis were generally excluded from resection, some cases identified during surgery were resected. Result In patients with resected stage III/IV GBC (n = 193), the period 2007–2013 (vs. 2000–2006, hazard ratio 0.63), pre-operative jaundice (hazard ratio 1.70), ≥ 2 liver metastases (vs. no liver metastasis, hazard ratio 2.11), and metastasis to the peritoneum (vs. no peritoneal metastasis, hazard ratio 2.08) were independent prognostic factors for overall survival, whereas one liver metastasis (vs. no liver metastasis) was not. When examining the 5-year overall survival and median survival times by liver metastasis in patients without peritoneal metastasis or pre-operative jaundice, those with one liver metastasis (63.5%, not reached) were comparable to those without liver metastasis (40.4%, 33.0 months), and was better than those with ≥ 2 liver metastases although there was no statistical difference (16.7%, 9.0 months). According to the univariate analysis of resected patients with GBC and liver metastases (n = 26), minor hepatectomy, less blood loss, less surgery time, papillary adenocarcinoma, and T2 were significantly associated with longer survival. Morbidity of Clavien–Dindo classification ≤ 2 and received adjuvant chemotherapy were marginally not significant. Long-term survivors (n = 5) had a high frequency of T2 tumors (4/5), had small liver metastases near the gallbladder during or after surgery, underwent minor hepatectomy without postoperative complications, and received postoperative adjuvant chemotherapy. Conclusions Although there is no surgical indication for GBC with liver metastasis diagnosed pre-operatively, minor hepatectomy and postoperative chemotherapy may be an option for selected patients with T2 GBC and liver metastasis identified during or after surgery who do not have other poor prognostic factors.

Abstract
Turbulence spreading into the edge stochastic magnetic layer induced by magnetic fluctuation is observed at the sharp boundary region in the large helical device. The density fluctuation excited at the sharp boundary region with a large pressure gradient does not propagate into the boundary region due to the blocking of turbulence spreading by the large second derivative of the pressure gradient. Once the magnetic fluctuation appears at the boundary, the density fluctuation begins to penetrate the edge stochastic layer and the second derivative of the pressure gradient also decreases. The increase of density fluctuation in this layer results in the broadening and reduction of the peak divertor heat load. It is demonstrated that magnetic fluctuation plays a key role in controlling the turbulence spreading at the boundary of plasma which contributes to the reduction of divertor heat load.

Abstract
In high-frequency pulsed magnets, such as kickers in particle accelerators, it is essential to reduce eddy currents that could be induced in the magnet core during excitation not to distort and attenuate the magnetic field pulse. A novel iron lamination scheme with additional interlaminar insulation is proposed for the magnet core of such pulsed magnets. A laminated steel sheet core is formed by alternately stacking thin steel and insulation sheets. For application to matched kicker magnets for accelerators, test magnets with the new and conventional iron lamination were designed, assembled, and extensively evaluated. The pulsed magnetic field waveforms of two test magnets with the new lamination successfully matched to below 0.1% over the entire pulse duration, which was significantly better than those with the conventional lamination. Among the applications of the developed high-frequency pulsed magnets, beam injection kickers for the coming next generation light sources and future colliders, where suppression of the transient stored-beam oscillation during beam injection is crucial, are considered to be promising.

Abstract
Gamma‐synuclein (SNCG) promotes invasive behavior and is reportedly a prognostic factor in a range of cancers. However, its role in biliary tract carcinoma (BTC) remains unknown. Consequently, we investigated the clinicopathological significance and function of SNCG in BTC. Using resected BTC specimens from 147 patients with adenocarcinoma (extrahepatic cholangiocarcinoma [ECC, n = 96]; intrahepatic cholangiocarcinoma [ICC, n = 51]), we immunohistochemically evaluated SNCG expression and investigated its correlation with clinicopathological factors and outcomes. Furthermore, cell lines with high SNCG expression were selected from 16 BTC cell lines and these underwent cell proliferation and migration assays by siRNAs. In the results, SNCG expression was present in 22 of 96 (22.9%) ECC patients and in 10 of 51 (19.6%) ICC patients. SNCG expression was significantly correlated with poorly differentiated tumor in both ECC and ICC (p = 0.01 and 0.03, respectively) and with perineural invasion and lymph node metastases in ECC (p = 0.04 and 0.003, respectively). Multivariate analyses revealed that SNCG expression was an independent poor prognostic factor in both OS and RFS in both ECC and ICC. In vitro analyses showed high SNCG expression in three BTC cell lines (NCC‐BD1, NCC‐BD3, and NCC‐CC6‐1). Functional analysis revealed that SNCG silencing could suppress cell migration in NCC‐BD1 and NCC‐CC6‐1 and downregulate cell proliferation in NCC‐CC6‐1 significantly. In conclusion, SNCG may promote tumor cell activity and is potentially a novel prognostic marker in BTC.

Abstract
Barré-Lièou syndrome (BLS) is a manifestation of various autonomic and secondary symptoms including muscle stiffness, tinnitus, dizziness, and pain in various body parts. Although considered to be caused by hyperactivation of the autonomic nervous system due to trauma, there is currently no firmly established etiology or evidence on the treatment and clinical features of BLS. We retrospectively examined the clinical features of BLS and evaluated the efficacy of trazodone (TZD) for its treatment. We conducted a retrospective analysis of the data of 20 consecutive cases with suspected BLS who were treated in our hospital between 2016 and 2019. BLS symptoms were rated on a 10-point scale, and two groups were defined, that is, a mild-BLS group (BLS scores, 1-5) and a severe-BLS group (BLS scores, 6-10). Univariate analysis of patient factors was performed. The BLS score was 6.0 ± 1.7, and the maximum TZD dose was 80 ± 34 mg/day; nine patients (45%) were TZD free, and no TZD side effects were observed, while all patients had a good clinical outcome. There were significant differences between the mild-BLS and severe-BLS groups in the period from injury to diagnosis (p = 0.015), chest/back pain (p < 0.001), constipation (p = 0.001), and maximum TZD dose (p = 0.008). BLS involves posttraumatic autonomic symptoms accompanied by depression and insomnia. The sympathetic hypersensitivity theory could explain its etiology. TZD could effectively and safely treat BLS, and early diagnosis and treatment can contribute toward good clinical outcomes. Enhanced recognition and understanding of this disease are warranted.

Abstract
Background: Intracranial hemorrhage after revascularization for acute ischemic stroke is associated with poor outcomes. Few reports have examined the relationship between parenchymal hematoma after revascularization and clinical outcomes. This retrospective study aimed to investigate the risk factors and clinical outcomes of parenchymal hematoma after revascularization for acute ischemic stroke. Methods: Ninety-three patients underwent revascularization for anterior circulation acute ischemic stroke. Patient characteristics and clinical outcomes were compared between patients with and without post procedural parenchymal hematoma using the following parameters: age, sex, occlusion location, presence of atrial fibrillation, diffusion-weighted imaging-Alberta stroke program early computed tomography score (DWI-ASPECTS), National Institute of Health Stroke Scale (NIHSS) score, recombinant tissue plasminogen activator, thrombolysis in cerebral infarction > 2b, door-to-puncture time, onset-to-recanalization time, number of passes, and modified Rankin Scale scores. Results: Parenchymal hematomas were not significantly correlated with age, sex, occlusion location, atrial fibrillation, DWI-ASPECTS, NIHSS score, recombinant tissue plasminogen activator, thrombolysis in cerebral infarction > 2b, door-to-puncture time, onset-to-recanalization time, and number of passes, but were significantly correlated with poor clinical outcomes (P = 0.001) and absence of the anterior communicating artery evaluated using pre procedural time-of-flight magnetic resonance angiography (P = 0.03). Conclusion: Parenchymal hematoma was a predictor of poor outcomes. In particular, the absence of the anterior communicating artery on pre procedural time-of-flight magnetic resonance angiography is a potential risk factor for parenchymal hematoma after revascularization for anterior circulation acute ischemic stroke.

Abstract
BACKGROUND Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is a biopsy technique widely used to diagnose pancreatic tumors because of its high sensitivity and specificity. Although needle-tract seeding caused by EUS-FNA has been recently reported, dissemination of pancreatic cancer cells is generally considered to be a rare complication that does not affect patient prognosis. However, the frequency of dissemination and needle-tract seeding appears to have been underestimated. We present a case of peritoneal dissemination of pancreatic cancer due to preoperative EUS-FNA.
CASE SUMMARY An 81-year-old man was referred to the Department of Surgery of our hospital in Japan owing to the detection of a pancreatic mass on computed tomography during medical screening. Trans-gastric EUS-FNA revealed that the mass was an adenocarcinoma; hence laparoscopic distal pancreatectomy with lympha-denectomy was performed. No intraoperative peritoneal dissemination and liver metastasis were visually detected, and pelvic lavage cytology was negative for carcinoma cells. The postoperative surgical specimen was negative for carcinoma cells at the dissected margin and the cut end margin; however, pathological findings revealed adenocarcinoma cells on the peritoneal surface proximal to the needle puncture site, and the cells were suspected to be disseminated via EUS- FNA. Hence, the patient received adjuvant therapy with S-1 (tegafur, gimeracil, and oteracil potassium); however, computed tomography performed 5 mo after surgery revealed liver metastasis and cancerous peritonitis. The patient received palliative therapy and died 8 mo after the operation.
CONCLUSION The indications of EUS-FNA should be carefully considered to avoid iatrogenic dissemination, especially for cancers in the pancreatic body or tail.

Abstract
PURPOSE The aim of this study was to investigate the usefulness of laparoscopic surgery for patients with postoperative abdominal symptoms, including chronic recurrent small-bowel obstruction (SBO), and preoperative examinations of barium follow-through and computed tomography (CT) to predict the postoperative outcomes of laparoscopic surgery. METHODS Between 2016 and 2018, 49 patients with postoperative symptoms were treated by laparoscopic surgery at our institute. The data from two preoperative examinations were available for 42 patients. The patients were divided into 4 groups: CT-positive (CP, n = 18), barium follow-through-positive (BP, n = 1), both positive (AP [all positive] n = 13), and both negative (AN [all negative], n = 10). RESULTS Among the 49 patients, 41 received pure laparoscopic surgery, 7 received laparoscopic-assisted surgery with mini-laparotomy, and 1 required conversion. Intra- and postoperative complications occurred in two and seven patients, respectively. Improvement of abdominal symptoms was observed in 40 patients. In terms of the medium-term outcomes, the rate of improvement of symptoms was poorer in the AN group than in the other three groups, but not to a significant degree. CONCLUSION Laparoscopic surgery was safe and feasible for patients with chronic recurrent abdominal symptoms, including SBO. Furthermore, in patients with negative results on both preoperative examinations, laparoscopic surgery may yield only poor improvement of symptoms.

Abstract
PURPOSE In this retrospective study, we investigated the status and validity of endoscopic transsphenoidal surgery (eTSS) for pituitary incidentalomas (PIs) as well as the value of basing the indication for surgery on the PI guidelines. METHODS Patients who underwent eTSS at Fukuoka University Chikushi Hospital between 2012 and 2018 were divided into the PI group and the non-PI group in accordance with the PI guideline of the Endocrine Society and their clinicopathological characteristics and outcomes were compared and analyzed. RESULTS A total of 59 patients were enrolled, with 35 patients in the PI group and 24 patients in the non-PI group. The diagnoses in the PI group were of non-functioning pituitary adenoma (NFPA) (n = 12, 34%), gonadotropin-producing pituitary adenoma (n = 8, 23%), Rathke cleft cyst (n = 7, 20%), meningioma (n = 4, 11%), and growth hormone-producing pituitary adenoma (n = 3, 9%); those in the non-PI group were of NFPA (n = 6, 25%), gonadotropin-producing pituitary adenoma (n = 3, 13%), Rathke cleft cyst (n = 3, 13%), growth hormone-producing pituitary adenoma (n = 3, 13%), and prolactin producing pituitary adenoma (n = 3, 13%). Regarding the preoperative factors, 1 patient in the PI group with panhypopituitarism was diagnosed with pituitary apoplexy (pure infarction) of an NFPA. The rates of postoperative anterior pituitary hormonal deficiencies (14% vs 46%, P = .015), residual tumor size (2 ± 5 vs 6 ± 7 mm, P = .008), and reoperation (n = 0, 0% vs n = 5, 21%, P = .005) were significantly different between the PI and non-PI groups. CONCLUSIONS This study showed that, postoperatively, the incidence of anterior pituitary hormonal deficiencies was lower in the PI than in the non-PI group, although it was comparable between the 2 groups before the operation. The patients in the PI group also had smaller residual tumors and a lower risk of reoperation than those in non-PI group. PIs could have a better postoperative clinical outcome than non-PIs when the indication for eTSS is based on preoperative scrutiny according to the PI guidelines and eTSS is performed by an experienced pituitary surgeon. Hence, more aggressive scrutiny and treatment for PIs might be desirable.

Abstract
Background Although surgery is the definitive curative treatment for biliary tract cancer (BTC), outcomes after surgery alone have not been satisfactory. Adjuvant therapy with S-1 may improve survival in patients with BTC. This study examined the safety and efficacy of 1 year adjuvant S-1 therapy for BTC in a multi-institutional trial. Methods The inclusion criteria were as follows: histologically proven BTC, Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1, R0 or R1 surgery performed, cancer classified as Stage IB to III. Within 10 weeks post-surgery, a 42-day cycle of treatment with S-1 (80 mg/m2/day orally twice daily on days 1–28 of each cycle) was initiated and continued up to 1 year post surgery. The primary endpoint was adjuvant therapy completion rate. The secondary endpoints were toxicities, disease-free survival (DFS), and overall survival (OS). Results Forty-six patients met the inclusion criteria of whom 19 had extrahepatic cholangiocarcinoma, 10 had gallbladder carcinoma, 9 had ampullary carcinoma, and 8 had intrahepatic cholangiocarcinoma. Overall, 25 patients completed adjuvant chemotherapy, with a 54.3% completion rate while the completion rate without recurrence during the 1 year administration was 62.5%. Seven patients (15%) experienced adverse events (grade 3/4). The median number of courses administered was 7.5. Thirteen patients needed dose reduction or temporary therapy withdrawal. OS and DFS rates at 1/2 years were 91.2/80.0% and 84.3/77.2%, respectively. Among patients who were administered more than 3 courses of S-1, only one patient discontinued because of adverse events. Conclusions One-year administration of adjuvant S-1 therapy for resected BTC was feasible and may be a promising treatment for those with resected BTC. Now, a randomized trial to determine the optimal duration of S-1 is ongoing. Trial registration UMIN-CTR, UMIN000009029.

Abstract
BACKGROUND Clinical and biological factors that predict liver volume recovery rate (LVRR) after liver resection of different resected volume (RV) have not been studied extensively. Moreover, it remains uncertain whether remnant liver volume influences the liver function recovery rate (LFRR). This study examined the predictive factors for LVRR after liver resections of different RV and investigated LFRR by focusing on LVRR improvements after hepatectomy. METHODS Patients who underwent hepatectomy between January 2013 and August 2015 were reviewed retrospectively. LVRR and LFRR were assessed at postoperative months (POMs) 3, 6, and 12. LVRR was evaluated on the basis of RV (0%-15%, 15%-30%, 30%-45%, and >45%). LFRR was evaluated using total bilirubin, prothrombin time, and platelet count. RESULTS LVRR was lower with more extensive liver resections. Significant independent predictors of LVRR were type IV collagen 7s domain levels and resection magnitude. Platelet count correlated positively with LVRR at all POMs. CONCLUSIONS Resected livers regenerated after surgery but did not reach preoperative volumes. Preserving the liver as much as possible during resection can result in greater LFRR after hepatectomy. Therefore, decisions regarding liver resection volume should be made very carefully, particularly in patients with higher type IV collagen 7s domain levels.

Abstract
BACKGROUND The periprocedural administration of dual antiplatelet therapy has been recommended in patients treated by carotid artery stenting. However, some patients with concurrent disease have been prescribed anticoagulants. We compared the post-operative incidence of hemorrhagic and thromboembolic events in two patient groups treated by different regimens of multi-antithrombotic agents. METHODS As our 31 patients had a history of nonvalvular atrial fibrillation, they had received anticoagulants; they were also treated with aspirin and clopidogrel before carotid artery stenting. The prior anticoagulant therapy was continued in 17 patients and they received vitamin K antagonist plus dual antiplatelet therapy after the procedure (group 1). Other 14 patients underwent direct oral anticoagulant plus aspirin or clopidogrel (group 2). Post-procedural hemorrhagic and thromboembolic events were compared between two groups. RESULTS Carotid artery stenting was angiographically successful in all patients. Complications were encountered in two group 1 patients. Post-operative image revealed a silent subarachnoid hemorrhage in one. The other presented with superior mesenteric artery occlusion 6 months after the procedure. No hemorrhagic or thromboembolic events occurred in group 2. CONCLUSION We concluded that the administration of a direct oral anticoagulant plus an antiplatelet agent reduced the risk for periprocedural hemorrhagic and embolic events in patients with concurrent nonvalvular atrial fibrillation who underwent carotid artery stenting.

Abstract
577 Background: Biliary tract carcinoma (BTC) is a highly malignant tumor, but the detailed pathological mechanism of its development and progression remain ill-defined. Gamma-synuclein (SNCG) promotes invasive behavior in pancreatic cancer and a range of other cancers, and SNCG expression is reportedly a prognostic factor. However, the role of SNCG in BTC remains unknown. Consequently, we investigated the clinicopathological significance and function of SNCG in BTC. Methods: Using surgically resected BTC specimens from 149 patients with adenocarcinoma [extrahepatic cholangiocarcinoma (ECC) (n =98); intrahepatic cholangiocarcinoma (ICC) (n =51)], we immunohistochemically evaluated SNCG positivity and checked for correlations with clinicopathological factors and outcomes. Furthermore, cell lines with high expressions of SNCG were selected from 17 BTC cell lines by using immunohistochemistry and qPCR. Cell proliferation and migration assays were then performed in the presence and absence of SNCG (silenced using). Results: SNCG expression was found in 32 of 149 (21.4%) BTC patients. SNCG expression was significantly correlated with poorly differentiated tumor ( P = 0.001) and lymph node metastases ( P = 0.001). SNCG positivity was also correlated with poorly differentiated tumor in both ECC and ICC ( P = 0.008 and P = 0.03, respectively), but was correlated with lymph node metastases only in ECC ( P = 0.003). Multivariate analyses identified SNCG expression as an independent prognostic factor of poor overall survival ( P = 0.008) and poor recurrence-free survival (RFS) ( P = 0.006). SNCG expression in both ECC and ICC was significantly associated with poor prognosis in univariate analysis, and multivariate analysis identified SNCG as an independent prognostic factor of poor RFS for ECC (P = 0.03). High SNCG expression was found in 3 BTC cell lines (NCC-BD1, NCC-BD3, and NCC-CC6-1). Functional analysis revealed that SNCG silencing by siRNA suppressed cell migration significantly in NCC-BD1 and NCC-CC6-1 and downregulated cell proliferation in NCC-CC6-1. Conclusions: Our results suggest that SNCG may promote tumor cell activity and is potentially a novel prognostic marker in BTC.

Abstract
BACKGROUND Bloodstream infection (BSI) is a life-threatening complication after living donor liver transplantation (LDLT). We aimed to explore the incidence and predisposing factors of BSI at our institution. METHODS We conducted a retrospective cohort analysis on all consecutive adults with BSI within 6 months after LDLT performed between 2005 and 2016. For antimicrobial prophylaxis, ampicillin/sulbactam, cefotaxime, and micafungin were administered. From 2011, methicillin-resistant Staphylococcus aureus (MRSA) carriers were decolonized using mupirocin ointment and chlorhexidine gluconate soap. Risk factors for BSI were identified by uni- and multivariate logistic regression. RESULTS Of a total of 106 LDLTs, 42 recipients (40%) suffered BSI. The BSI group demonstrated significantly higher in-hospital mortality rates compared with the non-BSI group (24% vs. 7%, P = .01). We identified MRSA carrier (odds ratio [OR], 19.1; P < .001), ABO incompatibility (OR, 2.9; P = .03), and estimated glomerular filtration rate <30 mL/min/1.73m2 (OR, 15.8; P = .02) as independent risk factors for BSI. Decolonization treatment for MRSA carriers did not reduce the incidence of all-cause BSI but reduced the frequency of BSI caused by MRSA. CONCLUSION To our knowledge, for the first time, MRSA carriers were revealed to be highly vulnerable to BSI after LDLT.

Abstract
BACKGROUND Survival benefit of liver resection for noncolorectal liver metastases (NCRLM) remains to be defined. METHODS This multicenter, retrospective cohort analysis included consecutive patients with NCRLM whose primary tumor and all metastases were treated with curative intent between 2000 and 2013. The primary endpoint was 5-year overall survival. Clinicopathological factors that affected prognoses were identified using multivariate Cox regression analyses and were included in a predictive model. RESULTS Data for 205 patients were analyzed. The three most common primary tumor sites were stomach (39%), pancreas (13%), and urinary tract (10%), with adenocarcinomas the main pathology (52%). R0 resection was achieved in 85%, and the overall survival at 5 years was 41%. In the multivariate analysis, synchronous liver metastases, R1/2 resection, and adenocarcinomas and other carcinomas (with gastrointestinal stromal tumors, neuroendocrine tumors G1/G2, and sarcomas set as the reference group) were independent negative indicators of overall survival. A predictive model effectively stratified the NCRLM patients into low-, intermediate-, and high-risk groups with overall 5-year survival rates of 63%, 38%, and 21%, respectively (P < 0.001). CONCLUSIONS Patients who underwent curative resection for metachronous disease and favorable tumor pathology are expected to have better survival in the NCRLM cohort.

Abstract
The resistive interchange mode destabilized by the resonant interaction with the trapped energetic ions is fully suppressed when the injected power of electron cyclotron heating exceeds a certain threshold. It is shown for the first time that the complete stabilization of the energetic-particle-driven mode without relaxing the energetic particle (EP) pressure gradient is possible by reducing the radial width of the eigenmodes δ_{w}, especially when δ_{w} narrows to a small enough value relative to the finite orbit width of EP.

Abstract
457 Background: The prognosis of intrahepatic cholangiocarcinoma (ICC) with lymph node metastases is dismal. Recent studies have highlighted the importance of lymph node retrieval from disease staging and therapeutic standpoints. To define the role of lymph node dissection for ICC, this study aimed to evaluate the patterns of lymph node metastases and their prognostic implication. Methods: A retrospective cohort analysis was conducted for 56 consecutive patients who underwent R0/R1 resection for ICC between 1990 and 2015. In principle, lymph nodes in the hepatic hilum and around the pancreas head were systematically removed. For left-sided tumors, lymph nodes in the lesser curvature of the stomach and the root of left gastric artery were also dissected. Clinicopathologic predictors of 3-year survival were identified by Cox multivariate analyses. Lymph node mapping was performed and positive nodes were classified into 3 compartments based on metastatic rates and prognoses. Results: Median tumor size, 4.5 (1.5–16.0) cm; Mass-forming and its dominant type, 42 (75%); R0 resection, 47 (84%). Nineteen (34%) patients had lymph node metastases. After excluding 4 in-hospital deaths, the overall and recurrence-free survival rates at 3 years were 66% and 33%, respectively (median follow-up, 36 months). Cox multivariate analysis revealed lymph node metastases [hazard ratio (HR) 6.3, 95% confidence interval (CI) 1.9-21.7, P = 0.003] and R1 resection (HR 7.8, 95% CI 1.6-38.3, P = 0.01) as independent negative predictors of overall survival. Patients with ≥ 4 positive nodes ( n = 7) had significantly decreased survival compared with those with 1–3 positive nodes ( n = 10, P= 0.005). Metastatic lymph nodes were classified into compartments I (metastatic rates ≥ 10% and longest survival ≥ 3 years), II (5%–10% and 1-year survival ≥ 50%), and III ( < 5% and 1-year survival < 50%). Lymph nodes in the suprapyloric area, celiac trunk, and paraaorta belonged to compartment III and appeared less important to be dissected. Conclusions: Systematic lymph node dissection for ICC based on tumor location provides accurate staging and may prolong survival in patients with limited number of positive nodes. Compartment classification is useful to determine the extent of dissection.

Abstract
Combined treatment strategies based on magnetic nanoparticles (MNPs) with near infrared ray (NIR) biophotonic possess tremendous potential for non-invasive therapeutic approach. Nonetheless, investigations in this direction have been limited to peripheral body region and little is known about the potential biomedical application of this approach for brain. Here we report that transient NIR exposure is dissipation-free and has no adverse effect on the viability and plasticity of major brain cells in the presence or absence superparamagnetic nanoparticles. The 808 nm NIR laser module with thermocouple was employed for functional studies upon NIR exposure to brain cells. Magnetic nanoparticles were characterized using transmission electron microscopy (TEM), X-ray diffraction (XRD), dynamic laser scattering (DLS), and vibrating sample magnetometer (VSM). Brain cells viability and plasticity were analyzed using electric cell-substrate impedance sensing system, cytotoxicity evaluation, and confocal microscopy. When efficacious non-invasive photobiomodulation and neuro-therapeutical targeting and monitoring to brain remain a formidable task, the discovery of this dissipation-free, transient NIR photonic approach for brain cells possesses remarkable potential to add new dimension.

Abstract
SETTING Lusaka, Zambia. OBJECTIVE To assess the actual treatment outcomes of 'transfer out' (TO) cases at a diagnostic centre in Lusaka, in the third and fourth quarters of 2012, and to see the impact of this cross-check in treatment success rates (TSR) in 2013 and early 2014. DESIGN AND METHOD In this retrospective cohort study, treatment outcomes for new bacteriologically positive tuberculosis (TB) cases referred from the diagnostic centre were reviewed and compared with those at the receiving treatment units. RESULTS Of 49 (58%) cases referred to three treatment units, the treatment outcomes of nine had to be updated at the diagnostic centre, which reduced the proportion of TO cases from 17.6% to 11.8% and increased the TSR to 70.6% from 64.7%. CONCLUSION The review and cross-checking of the TB registers at the diagnostic and treatment units led to a significant reduction in non-assessed cases, suggesting that the TB registers in the diagnostic and treatment units should be cross-checked regularly. There is also need for a complementary intervention to reduce the proportion of TOs associated with high loss to follow-up and non-evaluated TO rates.

Abstract
Aims This retrospective cohort study compared the results of vascularised and non-vascularised anterior sliding tibial grafts for the treatment of osteoarthritis (OA)of the ankle secondary to osteonecrosis of the talus. Patients and Methods We reviewed the clinical and radiological outcomes of 27 patients who underwent arthrodesis with either vascularised or non-vascularised (conventional) grafts, comparing the outcomes (clinical scores, proportion with successful union and time to union) between the two groups. The clinical outcome was assessed using the Mazur and American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scores. The mean follow-up was 35 months (24 to 68). Results The mean outcome scores increased significantly in both groups. In the vascularised graft group, the mean Mazur score improved from 36.9 to 74.6 and the mean AOFAS scale improved from 49.6 to 80.1. In the conventional arthrodesis group, the mean Mazur score improved from 35.5 to 65 and the mean AOFAS scale from 49.2 to 67.6. Complete fusion was achieved in 13 patients (76%) in the vascularised group, but only four (40%) in the conventional group. The clinical outcomes and proportion achieving union were significantly better in the vascularised group compared with the conventional arthrodesis group, although time to union was similar in the two groups. Take home message: Vascularised sliding tibial grafts may be used to achieve arthrodesis in patients with OA of the ankle secondary to osteonecrosis of the talus.

Abstract
A new method of vascularised tibial grafting has been developed for the treatment of avascular necrosis (AVN) of the talus and secondary osteoarthritis (OA) of the ankle. We used 40 cadavers to identify the vascular anatomy of the distal tibia in order to establish how to elevate a vascularised tibial graft safely. Between 2008 and 2012, eight patients (three male, five female, mean age 50 years; 26 to 68) with isolated AVN of the talus and 12 patients (four male, eight female, mean age 58 years; 23 to 76) with secondary OA underwent vascularised bone grafting from the distal tibia either to revascularise the talus or for arthrodesis. The radiological and clinical outcomes were evaluated at a mean follow-up of 31 months (24 to 62). The peri-malleolar arterial arch was confirmed in the cadaveric study. A vascularised bone graft could be elevated safely using the peri-malleolar pedicle. The clinical outcomes for the group with AVN of the talus assessed with the mean Mazur ankle grading scores, improved significantly from 39 points (21 to 48) pre-operatively to 81 points (73 to 90) at the final follow-up (p = 0.01). In all eight revascularisations, bone healing was obtained without progression to talar collapse, and union was established in 11 of 12 vascularised arthrodeses at a mean follow-up of 34 months (24 to 58). MRI showed revascularisation of the talus in all patients. We conclude that a vascularised tibial graft can be used both for revascularisation of the talus and for the arthrodesis of the ankle in patients with OA secondary to AVN of the talus.

Abstract
A fast two-dimensional soft X-ray camera using silicon photo diode array is being developed in order to investigate high frequency MHD instability with high mode number. The advantage of the adopted diode is a large sensor area of 10 mm × 10 mm and small diode capacitance which enable us to measure signals with the short response time. The characteristic of the prototype is summarized as follows: Channel number is 6 × 8 = 48, detection range 1∼10 keV, the spatial resolution 128 mm at the plasma location, and frequency range DC∼100 kHz. Synthetic image of the prototype in the Large Helical Device is estimated by using perturbation model of MHD mode.

Abstract
OBJECTIVE To examine the efficacy of the endoscope as an adjunct to the operating microscope in defining the surgical anatomy of the cerebellopontine angle (CPA). METHODS The surgical anatomy of the CPA was examined in cadaveric CPAs through a retrosigmoid approach. The upper, middle, and lower neurovascular complexes and the individual segments of the cerebellar arteries in the CPA were examined with the surgical microscope and 0° and 45° rigid endoscopes. RESULTS The microscope provided satisfactory views of the posterior surface of the neural and vascular structures in the central part of the CPA cistern. The endoscope provided superior views of the nerves' junction with the brainstem, their dural exit, and their vascular relationships. The endoscope also provided superior views of the individual segments of the cerebellar arteries. CONCLUSION The combination of endoscopic and microsurgical techniques aids in achieving optimal exposure in CPA surgery.

Abstract
ABSTRACTRecent advances in understanding the ALE (atomic layer epitaxy) growth of ZnSe, ZnS and ZnTe are reviewed. The Ideal ALE growth is obtained in the substrate temperature range of 250–350°C for ZnSe. In the ALE growth of ZnSe and ZnTe, a unique self-limiting mechanism is observed, in which the deposition rate saturates at 0.5 monolayer per cycle. Furthermore, applications of ALE of II–VI compounds to the growth of strained layer superlattices are also reviewed.

Abstract
Currently, the characteristics of aneurysms arising in the distal middle cerebral artery (dMCA) are not well understood. Here, we report the case of a 56-year-old woman with a ruptured saccular aneurysm in the M2 segment of the middle cerebral artery (MCA). The patient presented with a disturbance of consciousness, and computed tomography revealed a subarachnoid hemorrhage that angiography disclosed as a result of a saccular-type aneurysmal dilatation in the M2 segment of the left MCA. We excluded infection, inflammation, trauma, and neoplasia as causes of the aneurysm. Pathologic examination confirmed a ruptured saccular aneurysm of the dMCA that was unrelated to a branching zone. The aneurysmal wall was composed primarily of alphaSMA-positive and calponin/desmin-negative spindle cells and lacked internal elastic lamina, which was completely disrupted at the neck of the aneurysm. There was a strong positive immunoreactivity for matrix metalloproteinases (MMPs) 1, 2, and 9 in the spindle cells of the aneurysmal wall. In contrast, tests for MMP-8 were negative. The parent artery showed thickening of both the intima and media, with preservation of the internal elastic lamina. Atherosclerosis was not detected in either the parent artery or aneurysm. These findings suggest that an overexpression of MMPs may contribute to the development of saccular aneurysms in regions of the arterial trunk unrelated to branching zones.

Abstract
UNLABELLED We performed an intravenous glucose tolerance test (IVGTT) after the administration of triphenyltin chloride (TPTCl-Ad) in hamsters in order to confirm the presence of glucose intolerance and to clarify the pathogenesis of TPTCl-induced glucose intolerance. On the 1st, 2nd, 3rd, 4th and 7th days after TPTCl-Ad or the administration of sesame oil alone as a control, glucose was injected at a dose of 0.05 g glucose/100 g B.W., and then PG, IRI and TG were measured on 0, 1, 2, 3, 5 and 10 min after IVGTT. The TPT concentration in the pancreas was measured by gaschromatography and the morphological findings with a transmission electron microscope were compared between the TPTCl-Ad and the control hamsters. FPG on the 1st and the 2nd days after TPTCl-Ad were significantly higher than those in control, but those on the 4th and the 7th day recovered up to the control level. In contrast, basal IRI levels showed reciprocal results compared to the FPG levels. delta IRI/ delta PG on the 1st day after TPTCl-Ad was significantly reduced compared to the control. Fasting TG on the 1st day after TPTCl-Ad was much higher than the control. TPT-concentration on the 1st day after TPTCl-Ad showed peak values and its concentration gradually decreased. Electron microscopic findings in the pancreas after TPTCl-Ad indicated neither destruction nor lymphocyte infiltration of the pancreas. CONCLUSIONS The present data suggest that the administration of TPTCl in hamsters induces a functional transient damage on islet cells but not a morphological disorder, which shows an essentially different nature from the change in the pancreas induced by viral infection or by a large amount of streptozotocin.

Abstract
We report a case of ruptured tectal arteriovenous malformation (AVM) that was demonstrated angiographically only after removal of an unruptured occipital AVM. A 57-year-old man presented with sudden onset of diplopia and tinnitus. Computed tomography revealed a small hemorrhage in the right tectum mesencephali with intraventricular hemorrhage. Magnetic resonance imaging and angiography disclosed AVM in the right occipital lobe which was separate from the hemorrhagic lesion. Angiography demonstrated that the right occipital AVM was fed by the parieto-occipital artery and drained into the superior sagittal sinus and vein of Galen. However, no abnormal vascular lesion was detected near the tectum mesencephali. As venous hypertension was considered the reason for hemorrhage, the occipital AVM was completely resected. Postoperative angiography demonstrated disappearance of the occipital AVM, but it also disclosed a small tectal AVM fed by branches from the superior cerebellar artery, which had not been detected on preoperative angiography. This was considered the true cause of hemorrhage, and gamma knife surgery was accordingly performed. Even if an AVM is demonstrated, if the lesion does not correspond to the hemorrhage we recommend serial angiographical evaluation so that a small AVM is not missed.

Abstract
Aspirin exerts anti-thrombotic action by acetylating and inactivating cyclooxygenase-1, preventing the production of thromboxane A2 in platelets. Through this inhibition of platelet function, aspirin is considered as a preventative of ischemic diseases such as coronary and cerebral infarction. However, many studies have revealed that aspirin has other beneficial actions in addition to its anti-platelet activity. For example, aspirin may confer some benefit against colorectal cancer. Here, we discuss the involvement of inflammation in atherosclerosis and how aspirin exerts its beneficial actions in atherosclerotic diseases and cancer.
