Abstract
There have been no earlier reports of knee osteoarthritis with valgus knee deformity in which the patellar tendon infiltrates the tibial bone marrow instead of attaching to the tibial tubercle. This case report describes a total knee arthroplasty (TKA) performed for the treatment of a primary knee osteoarthritis resulting from a valgus knee joint position attributed to an abnormality of the patellar ligament attachment. During a TKA, the tendon tissue in the tibial medullary canal interfered with the reamer used to prepare for the stem extensions needed to improve the fixation of the component on the tibia, which had a cortical defect. The arthroplasty succeeded, and good clinical results have been maintained over the 3 years since the surgery. Surgeons should consider careful preoperative examinations by magnetic resonance imaging or CT when an abnormal bone defect is observed at the tibial tubercle on plain X-ray images.

Abstract
OBJECTIVE We performed a retrospective study to evaluate the risk factors for acquiring Pneumocystis pneumonia (PCP) by pharmacologically immunosuppressed HIV-negative patients. METHODS Patients who received corticosteroids, immunosuppressive agents, anticancer agents, and radiotherapy with or without trimethoprim-sulfamethoxazole (TMP-SMX) at Himeji Medical Center between 2010 and 2021 were evaluated. Drugs and doses of the treatments for each patient were divided by month into person-month units. Each person-month datum includes information on the administered drug (or radiotherapy), average doses, and whether the patient had PCP during the corresponding month. ROC curves with person-month data were generated for each treatment, and AUCs >0.7 were identified as possessing positive classification utility. The risks for PCP according to gender, age (grouped by median) and each treatment were examined by univariate analysis, followed by multivariate analysis to identify independent factors. RESULTS Of a total of 17,733 patients (214,676 person-months), 32 developed PCP. The cut-off values by ROC analysis were 13.7 mg/day for corticosteroid (prednisolone equivalent), 0.92 mg/day (6.45 mg/week) for methotrexate (MTX), and 34.3 mg/day for TMP-SMX. The cut-off values for other treatments could not be estimated. The above three drugs and male sex were significant variables in univariate analysis and were all confirmed as independent factors by multivariate analysis. CONCLUSION The results suggest that a monthly average dose of ≥13.7 mg/day of prednisolone, ≥0.92 mg/day of MTX and male sex are significant independent risk factors for PCP, and that prophylaxis with ≥34.3 mg/day of TMP-SMX is to be recommended.

Abstract
Quantitative structure-activity relationship (QSAR) models are powerful in silico tools for predicting the mutagenicity of unstable compounds, impurities and metabolites that are difficult to examine using the Ames test. Ideally, Ames/QSAR models for regulatory use should demonstrate high sensitivity, low false-negative rate and wide coverage of chemical space. To promote superior model development, the Division of Genetics and Mutagenesis, National Institute of Health Sciences, Japan (DGM/NIHS), conducted the Second Ames/QSAR International Challenge Project (2020-2022) as a successor to the First Project (2014-2017), with 21 teams from 11 countries participating. The DGM/NIHS provided a curated training dataset of approximately 12,000 chemicals and a trial dataset of approximately 1,600 chemicals, and each participating team predicted the Ames mutagenicity of each trial chemical using various Ames/QSAR models. The DGM/NIHS then provided the Ames test results for trial chemicals to assist in model improvement. Although overall model performance on the Second Project was not superior to that on the First, models from the eight teams participating in both projects achieved higher sensitivity than models from teams participating in only the Second Project. Thus, these evaluations have facilitated the development of QSAR models.

Abstract
BACKGROUND The Japanese guideline for therapeutic strategy in HCC does not recognize any benefit of preoperative chemotherapy for potentially resectable hepatocellular carcinoma (HCC), and only upfront resec tion is recommended even for an advanced HCC. Data on preoperative chemotherapy for advanced HCC is still limited. Poor prognostic factors of HCC after resection are tumor more than 5 cm in diameter, multiple lesions, and gross tumor thrombosis, which constitute UICC7 Stage IIIA and IIIB HCC. There are no prospective studies about preoperative chemotherapy in these patients. AIM To evaluate the benefit of preoperative chemotherapy for UICC7 Stage IIIA and IIIB potentially resectable HCC. DISCUSSION Our recent study demonstrated that the 5-year overall survival rate (OS) of patients diagnosed as UICC7 Stage IIIA and IIIB who had received upfront resection was only 16.5%. In contrast, the 5-year OS of UICC7 Stage IIIA and IIIB initially unresectable patients who had achieved conversion from unresectable to resect able status under successful hepatic infusion chemotherapy prior to resection was as high as 61.3%. Additionally, recent studies reported transarterial chemoembolization achieved outcomes comparable with those of resection. Therefore, we believe that patients with UICC7 Stage IIIA and IIIB should be considered borderline resectable. To evaluate this hypothesis we registered the present phase II clinical trial to assess the benefit of preoperative chemo therapy followed by hepatectomy in potentially resectable UICC7 Stage IIIA and IIIB HCC patients.

Abstract
INTRODUCTION Colorectal cancer (CRC) is one of the major life-threatening complications in patients with Crohn's disease (CD). Previous studies of CD-associated CRC (CD-CRC) have involved only small numbers of patients, and no large series have been reported from Asia. The aim of this study was to clarify the prognosis and clinicopathological features of CD-CRC compared with sporadic CRC. METHODS A large nationwide database was used to identify patients with CD-CRC (n = 233) and sporadic CRC (n = 129,783) over a 40-year period, from 1980 to 2020. Five-year overall survival (OS), recurrence-free survival (RFS), and clinicopathological characteristics were investigated. The prognosis of CD-CRC was further evaluated in groups divided by colon cancer and anorectal cancer (RC). Multivariable Cox regression analysis was used to adjust for confounding by unbalanced covariables. RESULTS Compared with sporadic cases, patients with CD-CRC were younger; more often had RC, multiple lesions, and mucinous adenocarcinoma; and had lower R0 resection rates. Five-year OS was worse for CD-CRC than for sporadic CRC (53.99% vs 71.17%, P < 0.001). Multivariable Cox regression analysis revealed that CD was associated with significantly poorer survival (hazard ratio 2.36, 95% confidence interval: 1.54-3.62, P < 0.0001). Evaluation by tumor location showed significantly worse 5-year OS and RFS of CD-RC compared with sporadic RC. Recurrence was identified in 39.57% of CD-RC cases and was mostly local. DISCUSSION Poor prognosis of CD-CRC is attributable primarily to RC and high local recurrence. Local control is indispensable to improving prognosis.

Abstract
Over the years, there has been considerable variation in the bull conception rate (BCR) of Japanese Black cattle; moreover, several Japanese Black bulls with a low BCR of ≤10% have been identified. However, the alleles responsible for the low BCR are not determined yet. Therefore, in this study, we aimed to identify single-nucleotide polymorphisms (SNPs) for predicting low BCR. To this end, the genome of Japanese Black bulls was comprehensively examined by a genome-wide association study with whole-exome sequencing (WES), and the effect of the identified marker regions on BCR was determined. The WES analysis of six sub-fertile bulls with a BCR of ≤10% and 73 normal bulls with a BCR of ≥40% identified a homozygous genotype for low BCR in Bos taurus autosome 5 in the region between 116.2 and 117.9 Mb. The g.116408653G > A SNP in this region had the most significant effect on the BCR (P-value = 1.0 × 10-23), and the GG (55.4 ± 11.2%) and AG (54.4 ± 9.4%) genotypes in the SNP had a higher phenotype than the AA (9.5 ± 6.1%) genotype for the BCR. The mixed model analysis revealed that g.116408653G > A was related to approximately 43% of the total genetic variance. In conclusion, the AA genotype of g.116408653G > A is a useful index for identifying sub-fertile Japanese Black bulls. Some positive and negative effects of SNP on the BCR were presumed to identify the causative mutations, which can help evaluate bull fertility.

Abstract
Recently, a certain volume of biopsy specimens has been required for genetic testing of tumors using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). This study aimed to verify the superiority of our newly devised EBUS-TBNA biopsy technique, the "cross-fanning technique," which combines rotation and up-down maneuvers, by comparing its harvest volume with that of other maneuvers. Using a bronchoscope simulator, ultrasonic bronchoscope, and 21-gauge puncture needle, we compared the weight of silicone biopsy specimens obtained by the following 4 procedures: Conventional maneuver; Up-down maneuver; Rotation maneuver, and; Cross-fanning technique. Each procedure was repeated 24 times in total, rotating the sequences of the maneuvers, and the operator/assistant pair to align the conditions. The means ± standard deviations of the sample volumes for each puncture technique were as follows: 2.8 ± 1.2 mg; 3.1 ± 1.6 mg; 3.7 ± 1.2 mg, and; 3.9 ± 1.2 mg. There was a significant difference between the 4 groups (P = .024). The post hoc test showed a statistically significant difference between techniques A and D (P = .019). This study showed that the cross-fanning technique might contribute to the increased volume of tissue samples obtained by EBUS-TBNA biopsy.

Abstract
OBJECTIVES Research suggests that cardiometabolic disease risks are elevated among survivors of natural disasters, possibly mediated by changes in diet. Using the Brief Dietary History Questionnaire, we examined (1) dietary patterns among older survivors of the 2011 Great East Japan Earthquake and Tsunami, and (2) the contribution of posttraumatic stress symptoms (PTSS)/depressive symptoms, as well as relocation to temporary housing on dietary patterns and (3) gender differences in the associations. DESIGN, SETTING AND PARTICIPANTS Data came from a prospective cohort study of 1,375 survivors aged 65-89 years (44.6% male). MEASUREMENTS PTSS/depression onset was evaluated in 2013, 2.5 years after the disaster. Dietary data was collected with a self-administered brief-type diet history questionnaire in 2020. A principal component analysis identified three posterior dietary patterns. RESULTS Diet 1 consisted of high intake of vegetables, soy products, and fruits; Diet 2 consisted of carbohydrate-rich foods and snacks/sweets; Diet 3 consisted of high intake of alcoholic beverages, meat, and seafood. Least-squares linear regression revealed that individuals with PTSS/depression were less likely to exhibit Diet 1, while individuals with PTSS were more likely to exhibit Diet 2 and 3. Especially, males who had depression showed an unhealthy dietary pattern. Those who have lived in a trailer-style temporary housing reported less consumption of Diet 3. CONCLUSION Survivors of disaster with symptoms of mental illness tended to exhibit less healthy dietary patterns after 9 years. Diet varied by type of post-disaster mental illness, gender, and current social circumstances. We lacked pre-disaster BDHQ data, which is a limitation.

Abstract
A 73-year-old woman was referred to our hospital after a liver tumor was discovered during an abdominal ultrasonography. Thirty-one years ago, she underwent a total hysterectomy for uterine myoma and was diagnosed with a leiomyoma. Twenty years ago, she underwent a bilateral oophorectomy for an ovarian tumor and was diagnosed with a luteinized theca cell tumor accompanied by sclerosing peritonitis. A CT scan and MRI revealed a 65-mm tumor in the S6-7 of the liver. There was no sign of any lesions other than in the liver, and TACE was performed for suspected hepatocellular carcinoma. However, a favorable treatment outcome was unable to be obtained and a posthepatic segmental resection was performed. Histopathological morphology suggested a similarity to endometrial stromal cells and, considering the history of myoma of the uterus and ovarian tumor, immunohistological staining was carried out. The myoma of the uterus and the ovarian and liver tumors were all CD10(+), α⊖SMA(-), MIB-1 index 3%. The uterine myoma, which was initially operated on, was rediagnosed as a low-grade endometrial stromal sarcoma. After 11 years, ovarian metastasis was observed, and after 31 years liver metastasis occurred. Examples of resection of liver metastasis of endometrial stromal sarcoma are extremely rare and, we will include a review of the literature in this report.

Abstract
BACKGROUND/AIM Studies have indicated that liver mobilization during hepatectomy could cause the dissemination of tumor cells. However, the data are still limited in terms of the relationship between circulating tumor cells (CTCs) and surgical procedures. PATIENTS AND METHODS Fifteen patients who underwent hepatectomy for primary hepatocellular carcinoma (HCC) were included in the study. Blood samples were collected from the portal vein, central vein, and peripheral artery at three time points, namely, before mobilization (BM) of the liver, during transection (DT) of parenchyma, and after resection (AR) of the tumor. To detect CTCs, a real-time PCR assay was performed using primers for the epithelial cell adhesion molecule, cytokeratin 18, and glypican 3. Patients were divided into anterior approach (AA) and non-AA (NA) groups. In the AA group, patients underwent an initial hilar vascular dissection followed by a liver hanging maneuver during transection. RESULTS Seven patients were allocated to the AA group, and eight to the NA group. In the NA group, CTC levels in the portal vein were significantly increased at DT and AR compared to BM. In cases with large HCC (>70 mm), CTC levels in central venous blood were significantly increased at DT and AR in the NA group. CONCLUSION The AA liver resection technique may minimize CTC dissemination, improving the prognosis of patients with HCC.

Abstract
PURPOSE The prognostic value of F-18 fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) taken immediately after completion of radiotherapy in lung cancer patients is not well known. The purpose of this study is to assess the prognostic value of PET/CT taken immediately after completion of radiotherapy in lung cancer patients. MATERIALS AND METHODS Patients with primary lung cancer planned to undergo concurrent chemoradiotherapy were enrolled. Patients underwent PET/CT scans at 3 time points: before radiotherapy, within 24hours of completing radiotherapy (im-PET/CT), and 2-9 months after radiotherapy (post-PET/CT). Maximum standardized uptake value (SUVmax) was obtained. A post-PET/CT-SUVmax cut-off of 2.5 was determined as radiotherapy success. RESULTS Nineteen patients were enrolled. im-PET/CT-SUVmax for patients in the high post-PET/CT-SUVmax group was significantly higher than that of the low group (P=0.004). Receiver operator curve analysis indicated that im-PET/CT-SUVmax of 4.35 was an optimal cut-off value to discriminate between the two groups. Multivariable analysis showed that a high im-PET/CT-SUVmax was significantly associated with a high post-PET/CT-SUVmax (P=0.003). CONCLUSION PET/CT-SUVmax taken immediately following radiotherapy was associated with that evaluated 2-9 months after radiotherapy.

Abstract
Anal canal cancer (ACC) has been reported to be an uncommon cancer in Japan, as in the USA, Europe, and Australia. This retrospective multi‐institutional study was conducted to clarify the characteristics of ACC in Japan. First, the histological ACC type cases treated between 1991 and 2015 were collected. A detailed analysis of the characteristics of anal canal squamous cell carcinoma (SCC) cases was then conducted. The results of the histological types revealed that of the 1781 ACC cases, 435 cases (24.4%) including seven cases of adenosquamous cell carcinomas were SCC and 1260 cases (70.7%) were adenocarcinoma. However, the most common histological type reported in the USA, Europe, and Australia is SCC. Most ACC cases are adenocarcinomas and there is a low incidence of SCC in Japan which is different from the above‐mentioned countries. Moreover, we reclassified T4 into the following two groups based on tumor size: T4a (tumor diameter of 5 cm or less) and T4b (tumor diameter of more than 5 cm). The results of the TNM classification of SCC revealed that the hazard ratio (HR) to T1 of T2, T3, T4a, and T4b was 2.45, 2.28, 2.89, and 4.97, respectively. As T4b cases had a worse prognosis than T4a cases, we propose that T4 for anal canal SCC in Japan be subclassified into T4a and T4b.

Abstract
This study retrospectively compared the perioperative bleeding, hemodynamics, and clinical outcomes of total knee arthroplasty (TKA) performed with and without a tourniquet between two age groups. We grouped 103 patients with knee osteoarthritis who underwent primary TKA based on age at surgery: <76 years and ≥76 years. Tourniquet was used for TKA until March 2010 and stopped thereafter; hence, the patients were further classified according to TKA performed with or without a tourniquet. The differences in the operation time; perioperative bleeding; estimated bleeding; and hemoglobin (Hb) and hematocrit (Ht) levels immediately, 1 day, and 7 days postoperatively were evaluated. The clinical outcomes for range of motion, and Knee Society Knee Scores preoperatively and at 4 weeks postoperatively were assessed. Operation time was longer in the ≥76-year-old non-tourniquet group. No difference was observed in estimated bleeding among the groups. Changes in the Hb and Ht levels at postoperative days 1 and 7 were negatively correlated with age but were not different for TKA performed with or without a tourniquet in the ≥76-year-old-patient group. There were no differences in clinical outcomes among the groups. TKA can be performed with or without a tourniquet in patients aged ≥ 76 years with careful assessment of postoperative anemia.

Abstract
Abstract
Background
Cardiac myosin–binding protein C (cMyC) is a cardiac-restricted protein that has more abundant, rapid release and clearance kinetics than cardiac troponin. The current ESC guideline suggests the cMyC may provide value as an alternative to cardiac troponin. The 99th percentile value is universally endorsed as the reference cut off to aid in the diagnosis of acute myocardial infarction (AMI), however, none of the report of healthy population of cMyC.
Purpose
The aim of this study was to evaluate the distribution of cMyC values in healthy subjects.
Methods
We used two cohorts in this retrospective study. 1) Healthy subjects; a total of 500 subjects (250 men and 250 women) who had annual health examinations in 2012 in the area of Kamigoto, a suburb of Nagasaki city in Southern Japan were enrolled. All participants showed none of abnormal findings including cell blood counts, chemical analysis, liver function tests, general urine tests, occult blood tests of stool, barium swallow, mammography for women, abdominal ultrasound sonography, and electrocardiogram. All blood samples were obtained in a fasting state in the morning. 2) Chest pain subjects; we collected samples from 250 subjects including 50 with non-ST elevation myocardial infarction visited admitted to a university hospital for measurement of high-sensitivity troponin T and coronary artery assessment by coronary angiography. We measured cMyC level in both cohorts by HISCL™-800 system (Sysmex corporation, Japan). The assay has a limit of detection of 0.5 ng/L and a lower limit of quantification of 1.3 ng/L.
Result
In healthy subjects, median age (IQR) was 44 (20, 82) in men and 50 (23, 91) in women. The 99th percentile of cMyC was 27.3 ng/L, which was around one-third lower than that in previous report (87 ng/L). In chest pain subjects, the concentrations of cMyC at presentation were significantly higher in those with versus without AMI (median, 66 ng/L versus 10 ng/L, P<0.001). Discriminatory power for AMI, as quantified by the area under the receiver-operating characteristic curve (AUC), was comparable for cMyC (AUC, 0.85 (95% CI 0.79–0.91) and hs-cTnT (AUC, 0.81 (95% CI 0.76–0.88)).
Conclusion
We defined the normal range of cMyC in healthy Japanese subjects. The level of cMyC at presentation provides discriminatory power comparable to hs-cTnT in the diagnosis of AMI. To determine the physiological value of a biomarker may be necessary to evaluate enough information about their health status.

Abstract
Vaccine confidence reflects social, individual, and political factors indicating confidence in vaccines and associated health systems. In Japan, the government ceased proactive recommendation of the human papillomavirus (HPV) vaccine in June 2013, only several months after the recommendation had begun. Seven years later, as of October 2020, the suspension persists and vaccine coverage has precipitously declined, resulting in many young women being continually exposed to the risk of preventable HPV-related diseases. Accordingly, understanding stakeholder opinions on HPV vaccination issues is critical for informing strategies to improve HPV vaccine confidence and acceptance. In October 2019, we performed a nationwide, web-based survey of 1646 mothers of HPV-vaccination–eligible girls, 562 female adolescents aged 15–19 years, and 919 healthcare professionals (HCPs) in Japan. This survey captured key elements of vaccine confidence (i.e., importance, effectiveness, and safety of the HPV vaccine), awareness, and the willingness to receive (in HPV-vaccination–eligible girls) or recommend (in HCPs) the HPV vaccine, and the factors responsible for these decisions. HPV vaccine confidence was generally higher among HCPs than among mothers or female adolescents. Nearly half of all stakeholders were neutral regarding their willingness to receive/recommend the HPV vaccine. The seriousness of cervical cancer and the HPV vaccine’s effectiveness or safety were important deciding factors for receiving/recommending the HPV vaccine. Besides these factors, sufficient information and free vaccination were crucial. Our results suggest several factors that could help shape public policy and communication strategies to improve HPV vaccine confidence and acceptance in Japan.

Abstract
BACKGROUND The prognostic nutritional index (PNI) is used to assess immune and nutritional status, and is a prognostic factor for several malignant tumors. However, little evidence exists regarding the predictive impact of prognostic nutritional index (PNI) after local ablation therapy for hepatocellular carcinoma (HCC). The aim of this study was to evaluate the value of PNI to predict recurrence and survival after operative microwave ablation in patients with early-stage HCC. METHODS This retrospective study included 341 patients who underwent operative microwave ablation for HCC in Barcelona Clinic Liver Cancer (BCLC) stage 0-A at our institute between 2007 and 2015. We analyzed overall survival (OS) and recurrence-free survival (RFS), and evaluated factors related to prognosis in multivariate Cox regression analyses. RESULTS The OS rates at 1, 3, 5, and 10 years after microwave ablation were 100%, 92.7%, 85.1%, and 57.5% in patients with high-PNI levels, and 96.5%, 78.2%, 59.7%, and 20.7% in patients with low-PNI levels, respectively (P < 0.001). The RFS rates at 1, 3, 5, and 10 years after microwave ablation were 96.3%, 75.2%, 55.4%, and 30.4% in patients with high-PNI levels, and 94.4%, 48.8%, 36.4%, and 13.1% in patients with low-PNI levels, respectively (P < 0.001). In multivariate analyses, preoperative PNI level was an independent prognostic factor for both OS and RFS. CONCLUSION Our results revealed the preoperative PNI level was a simple and novel predictive marker of survival and recurrence after microwave ablation in patients with early-stage HCC.

Abstract
Electron correlation in a quantum many-body state appears as peculiar scattering behaviour at its boundary, symbolic of which is Andreev reflection at a metal-superconductor interface. Despite being fundamental in nature, dictated by the charge conservation law, however, the process has had no analogues outside the realm of superconductivity so far. Here, we report the observation of an Andreev-like process originating from a topological quantum many-body effect instead of superconductivity. A narrow junction between fractional and integer quantum Hall states shows a two-terminal conductance exceeding that of the constituent fractional state. This remarkable behaviour, while theoretically predicted more than two decades ago but not detected to date, can be interpreted as Andreev reflection of fractionally charged quasiparticles. The observed fractional quantum Hall Andreev reflection provides a fundamental picture that captures microscopic charge dynamics at the boundaries of topological quantum many-body states. Andreev reflection is normally known to occur at a metal-superconductor interface. Here, Hashisaka et al. observe an Andreev-like process in a narrow junction between fractional and integer quantum Hall states originating from a topological quantum many-body effect instead of superconductivity.

Abstract
The geriatric nutritional risk index (GNRI) is widely used for nutritional assessment in older inpatients and is associated with postoperative complications and cancer prognosis. We investigated the use of GNRI to predict long-term outcomes in hepatocellular carcinoma of all etiologies after hepatectomy. Overall, 346 patients were examined after propensity score matching. We dichotomized the GNRI score into high GNRI (> 98: N = 173) and low GNRI (≤ 98: N = 173) and evaluated recurrence-free survival (RFS) and overall survival (OS) between both groups. Clinicopathological characteristics between the low- and high-GNRI groups were similar after propensity score matching except for the components of the GNRI score (body mass index and serum albumin level), Child–Pugh score (comprising serum albumin level), and preoperative alpha-fetoprotein level (p < 0.0001, p < 0.0001, p = 0.0030, and p = 0.0007, respectively). High GNRI was associated with significantly better RFS and OS (p = 0.0003 and p = 0.0211, respectively; log-rank test). Multivariate analysis revealed that GNRI is an independent prognostic factor of RFS and OS (low vs. high; hazard ratio [HR], 1.8284; 95% confidence interval [CI] 1.3598–2.4586; p < 0.0001, and HR, 1.5452; 95% CI 1.0345–2.3079; p = 0.0335, respectively). GNRI is an objective, inexpensive, and easily calculated assessment tool for nutritional status and can predict prognosis of hepatocellular carcinoma after hepatectomy.

Abstract
BACKGROUND Little is known about the survival outcomes of and predictive factors for survival in hemodialysis patients undergoing surgery for gastric cancer. METHODS We performed a multicenter retrospective study from 9 institutions to investigate the survival outcomes of 75 hemodialysis patients with gastric cancer. Patient characteristics included demographic data, hemodialysis- and gastric cancer-related variables. Multivariate Cox hazards models were applied to determine independent predictors of poor overall survival and non-gastric cancer related death. RESULTS Stage I disease was predominant (58.7%) in our series. The overall morbidity and the 30-day mortality rates were 25.3% and 1.3%, respectively. The 5-year overall survival rates of patients with pStages I, II, III, and IV disease were 59.2%, 42.9%, 32.3%, and 0%, respectively. Eleven (14.7%) patients died of gastric cancer, whereas many more (40.0%) died owing to causes other than gastric cancer. Non-gastric cancer-related death was especially prevalent in patients with pStages I (95.2%) and II (75.0%) disease. Multivariable analysis revealed advanced age, long duration of hemodialysis (> 5 years), total gastrectomy, and pStage IV disease to be independently associated with poor overall survival. Notably, advanced age, long duration of hemodialysis, and the presence of cardiovascular disease were all independent predictors of non-gastric cancer-related death. Patients with all 3 factors had very poor survival outcomes (3-year overall survival; 14.3%). CONCLUSION The survival outcomes of hemodialysis patients with gastric cancer, especially those with early-stage gastric cancer, were clearly poor, largely owing to the increased risk of non-gastric cancer-related death. Preoperative comorbidities and hemodialytic features were useful for predicting long-term outcomes of this vulnerable population.

Calf mortality is a major problem affecting cattle production. To identify genetic variants associated with calf mortality in Japanese Black cattle, we evaluated calf mortality as a categorical trait using a threshold model and conducted a GWAS. We identified two SNPs between 32 549 297 and 32 606 924 bp on bovine chromosome 9 that were significantly associated with calf mortality from 61 to 180 days after birth. The SNP showing the highest association was localized at a region 624 bp downstream of exon 4 of the anti-silencing function 1A histone chaperone gene (ASF1A) that promotes DNA damage repair, and the null mice, which exhibit pre- and postnatal lethality. This association was also detected using the breeding value of 334 sires. The frequency of the risk allele in Japanese Black cattle from locations across Japan was 0.013; although the frequency of ASF1A risk allele was low, it is widespread in the Japanese Black cattle population. Thus, it may be necessary to routinely monitor the cattle population for the presence of this allele.

Abstract
Background Pancreatic trauma is a rare condition with a wide presentation, ranging from hematoma or laceration without main pancreatic duct involvement, to massive destruction of the pancreatic head. The optimal diagnosis of pancreatic trauma and its management approaches are still under debate. The East Association of Surgery for Trauma (EAST) guidelines recommend operative management for high-grade pancreatic trauma; however, several reports have reported successful outcomes with nonoperative management (NOM) for grade III/IV pancreatic injuries. Herein, we report a case of grade IV pancreatic injury that was nonoperatively managed through endoscopic and percutaneous drainage. Case presentation A 47-year-old Japanese man was stabbed in the back with a knife; upon blood examination, both serum amylase and lipase levels were within normal limits. Contrast-enhanced computed tomography (CT) showed extravasation of the contrast medium around the pancreatic head and a hematoma behind the pancreas. Abdominal arterial angiography revealed a pseudo aneurysm in the inferior pancreatoduodenal artery, as well as extravasation of the contrast medium in that artery; coil embolization was thus performed. On day 12, CT revealed a wedge-shaped, low-density area in the pancreatic head, as well as consecutive pseudocysts behind the pancreas; thereafter, percutaneous drainage was performed via the stab wound. On day 22, contrast radiography through the percutaneous drain revealed the proximal and distal parts of the main pancreatic duct. The injury was thus diagnosed as a grade IV pancreatic injury based on the American Association for the Surgery of Trauma guidelines. On day 26, an endoscopic nasopancreatic drainage tube was inserted across the disruption; on day 38, contrast-enhanced CT showed a marked reduction in the fluid collection. Finally, on day 61, the patient was discharged. Conclusions Although the EAST guidelines recommend operative treatment for high-grade pancreatic trauma, NOM with appropriate drainage by endoscopic and/or percutaneous approaches may be a promising treatment for grade III or IV trauma.

Abstract
59 Background: As previously reported (Sunami E, et al. Clin Colorectal Cancer. 2020), the ACTS-CC 02 trial demonstrated that S-1 and oxaliplatin (SOX) was not superior to UFT/leucovorin (LV) in terms of disease-free survival (DFS) as adjuvant chemotherapy for high-risk stage III colon cancer (any T, N2, or positive nodes around the origin of the feeding arteries). We now report the final overall survival (OS) after a median follow-up of more than 6 years. Methods: A total of 966 patients with high-risk stage III colon cancer were randomly assigned to receive either UFT/LV (300–600 mg/day of UFT according to body surface area [BSA] and 75 mg/day of LV on days 1-28, every 35 days, 5 courses) or SOX (100 mg/m2 of oxaliplatin on day 1 and 80–120 mg/day of S-1 according to BSA on days 1-14, every 21 days, 8 courses). The primary endpoint was DFS. Patients’ data were updated in February 2020. Results: The subjects of this final efficacy analysis were 955 patients (478 in the UFT/LV group and 477 in the SOX group). Totally, Stage IIIA/IIIB/IIIC were 1.3%/50.2%/48.6% and T1/2/3/4 were 1.5%/4.0%/61.8%/32.7%. With median follow-up time of 74.3 months, the 5-year OS rate was 78.3% in the UFT/LV group and 79.1% in the SOX group (HR: 0.97; 95% CI: 0.76-1.24; p = 0.8175). The 5-year DFS rate was 55.2% in the UFT/LV group and 58.1% in the SOX group (HR: 0.92; 95% CI: 0.76-1.11; p = 0.3973). In an exploratory analysis, the 5-year OS rate in patients with T4 disease was 65.2% and 70.8% in the UFT/LV group and SOX group, respectively (HR: 0.81; 95% CI: 0.56-1.17), and the 5-year DFS rate was 45.4% and 50.5% (HR: 0.87; 95% CI: 0.65-1.19), respectively. Notably, in patients with T4N2b disease, the 5-year OS rate was 51.0% and 64.1% in the UFT/LV group and SOX group, (HR: 0.72; 95% CI: 0.40-1.31) and the 5-year DFS rate was 31.1% and 37.2% (HR: 0.87; 95% CI: 0.50-1.31), respectively. Conclusions: In Japanese patients with high-risk stage III colon cancer, the 5-year OS rate was similar in the UFT/LV group and SOX group. However, the oxaliplatin-based regimen was suggested to be more effective for DFS and OS in patients with advanced disease, such as T4N2b. Clinical trial information: JapicCTI-101073.

Abstract
BACKGROUND Tumor thrombus in the superior mesenteric vein secondary to colon cancer is rare. We report a case of tumor thrombus in the superior mesenteric vein and liver metastasis due to advanced colon cancer that was treated with chemotherapy and complete surgical resection. CASE PRESENTATION A 72-year-old man after transverse colectomy with lymph node dissection for advanced colon cancer was diagnosed with tumor thrombus in the superior mesenteric vein and liver metastasis. He underwent adjuvant chemotherapy and had complete surgical tumor resection involving tumor thrombectomy and hepatectomy. There has been no recurrence at 36 months after surgery. CONCLUSION Herein, we report a rare case of tumor thrombus in the superior mesenteric vein related to advanced colon cancer. The combination of chemotherapy and complete surgical tumor resection may provide long-term survival.

Abstract
BACKGROUND Intersphincteric resection (ISR) has been increasingly used as the ultimate sphincter-preserving procedure in extremely low rectal cancer. The most critical complication of this technique is anastomotic leakage. The incidence rate of anastomotic leakage after ISR has been reported to range from 5.1% to 20%.
AIM To investigate risk factors for anastomotic leakage after ISR based on clinicopathological variables and pelvimetry.
METHODS This study was conducted at Department of Colorectal Surgery, Japanese Red Cross Medical Center, Tokyo, Japan, with a total of 117 patients. We enrolled 117 patients with extremely low rectal cancer who underwent laparotomic and laparoscopic ISRs at our hospital. We conducted retrospective univariate and multivariate regression analyses on 33 items to elucidate the risk factors for anastomotic leakage after ISR. Pelvic dimensions were measured using three-dimensional reconstruction of computed tomography images. The optimal cutoff value of the pelvic inlet plane area that predicts anastomotic leakage was determined using a receiver operating characteristic (ROC) curve.
RESULTS We observed anastomotic leakage in 10 (8.5%) of the 117 patients. In the multivariate analysis, we identified high body mass index (odds ratio 1.674; 95% confidence interval: 1.087-2.58; P = 0.019) and smaller pelvic inlet plane area (odds ratio 0.998; 95% confidence interval: 0.997-0.999; P = 0.012) as statistically significant risk factors for anastomotic leakage. According to the receiver operating characteristic curves, the optimal cutoff value of the pelvic inlet plane area was 10074 mm2. Narrow pelvic inlet plane area (≤ 10074 mm2) predicted anastomotic leakage with a sensitivity of 90%, a specificity of 85.9%, and an accuracy of 86.3%.
CONCLUSION Narrow pelvic inlet and obesity were independent risk factors for anastomotic leakage after ISR. Anastomotic leakage after ISR may be predicted from a narrow pelvic inlet plane area (≤ 10074 mm2).

Abstract
Resistance to third-generation cephalosporins and carbapenems in Gram-negative bacteria is chiefly mediated by beta-lactamases including extended-spectrum beta-lactamase (ESBL), AmpC, and carbapenemase enzymes. Routine phenotypic detection methods do not provide timely results, and there is a lack of comprehensive molecular panels covering all important markers. An ESBL/carbapenemase high-resolution melt analysis (HRM) assay (SHV, TEM, CTX-M ESBL families, and NDM, IMP, KPC, VIM and OXA-48-like carbapenemases) and an AmpC HRM assay (16S rDNA control, FOX, MOX, ACC, EBC, CIT, and DHA) were designed and evaluated on 111 Gram-negative isolates with mixed resistance patterns. The sensitivity for carbapenemase, ESBL, and AmpC genes was 96.7% (95% confidence interval [CI]: 82.8-99.9%), 93.6% (95% CI: 85.7-97.9%), and 93.8% (95% CI: 82.8-98.7%), respectively, with a specificity of 100% (95% CI: 95.6-100%), 93.9% (95% CI: 79.8-99.3%), and 93.7% (95% CI: 84.5-98.2%). The HRM assays enable the simultaneous detection of the 14 most important ESBL, carbapenemase, and AmpC genes and could be used as a molecular surveillance tool or to hasten detection of antimicrobial resistance for treatment management.

Abstract
Experiments using a THz pump and an X-ray probe at an X-ray free-electron laser (XFEL) facility like the Linac Coherent Light Source II (LCLS II) require frequency-tunable (3 to 20 THz), narrow bandwidth (∼10%), carrier-envelope-phase-stable THz pulses that produce high fields (>1 MV cm-1) at the repetition rate of the X-rays and are well synchronized with them. In this paper, a two-bunch scheme to generate THz radiation at LCLS II is studied: the first bunch produces THz radiation in an electromagnet wiggler immediately following the LCLS II undulator that produces X-rays from the second bunch. The initial time delay between the two bunches is optimized to compensate for the path difference in THz transport. The two-bunch beam dynamics, the THz wiggler and radiation are described, as well as the transport system bringing the THz pulses from the wiggler to the experimental hall.

Abstract
Background Gastroenteric neuroendocrine carcinomas (NECs) account for 6.2% of gastroenteric neuroendocrine tumors (NETs), and only 1% or less of gastroenteric NETs occur in the ampulla of Vater (AoV). Clinical features of NEC of the AoV remain obscure. Case presentation A 65-year-old man visited a general practitioner because of jaundice, and an abdominal contrast-enhanced computed tomography scan revealed a tumor of 11 mm in diameter, which was enhanced in the arterial phase at the duodenal papilla, with dilation of the upstream bile duct. Gastrointestinal scope revealed an unexposed tumor of the AoV. Based on a biopsy of the site, a moderately differentiated tubular adenocarcinoma was suspected, and pancreatoduodenectomy was performed. Histopathological examination revealed dysplasia and highly proliferative small tumor cells, with solid and nodular formation at the AoV. Histological analysis showed a high mitotic count, and immunohistochemical staining revealed a Ki-67 index of 40–50% and cells positive for synaptophysin, chromogranin A, and p53. Small cell-type NEC was finally diagnosed. Four months post pancreatoduodenectomy, multiple liver metastases developed, and systemic chemotherapy was administered. Salvage liver resection for liver metastases was performed 14 months after the pancreatoduodenectomy. Unfortunately, multiple liver metastases developed 2 months after liver resection, and the patient died 18 months after the pancreatoduodenectomy. Conclusions Neuroendocrine carcinoma originating from the bile duct is very rare; therefore, in this article, we provide a review of the literature and a case report.

Abstract
BACKGROUND It remains to be clarified whether combined hepatectomy and microwave ablation for multifocal hepatocellular carcinoma (HCC) is feasible. This aim of this study was to examine the perioperative and oncological outcomes after combined hepatectomy and microwave ablation for multifocal HCC. METHODS This retrospective study included 81 patients who underwent combined hepatectomy and microwave ablation for multifocal HCC in our institute between June 1998 and December 2017. We analyzed overall survival (OS) and recurrence-free survival (RFS), and evaluated factors related to prognosis. RESULTS Median follow-up time was 45.6 months for the entire cohort. OS rates were 1-year: 96%, 3-year: 72%, and 5-year: 54%; RFS rates were 1-year: 77%, 3-year: 37%, and 5-year: 22%. The major complication rate (Clavien-Dindo classification IIIa or above) after surgery was 10%, with one patient of in-hospital mortality. Multivariate analysis revealed that des-γ-carboxy prothrombin level >200 mAU/mL and >5 tumors were independent risk factors for OS, and des-γ-carboxy prothrombin level >200 mAU/mL, > 5 tumors, and maximum tumor size >5 cm were independent risk factors for RFS. CONCLUSIONS Our results indicate that combined hepatectomy and microwave ablation is safe and feasible for selected patients with multifocal HCC.

Abstract
A 73-year-old male was initially treated with sorafenib for advanced stage HCC. However, the disease progressed 2 months after starting sorafenib. Progressive disease (PD) was confirmed by radiological examination, which revealed mediastinal and abdominal lymph node metastasis, pulmonary metastasis, and intrahepatic recurrence. The patient was enrolled in the REACH-2 (NCT02435433) trial and randomized to receive ramucirumab (8 mg/kg div. every 2 weeks). The patient had a Child–Pugh score of 6A and his AFP level was found to be 1,256.8 ng/mL at initiation. Radiological examination revealed PD, 5 months after starting ramucirumab. Ramucirumab treatment was continued after the confirmation of radiological PD, not but clinical progression, as allowed by the study protocol. His AFP level increased after continuous ramucirumab treatment, however, it suddenly decreased from 7,653 ng/mL to within normal limits 10 months after initiation of ramucirumab treatment. Radiological evaluation revealed a significant decrease in the size of the tumors, which constituted a partial response (PR). We reported a rare case of advanced HCC with PR to a continuous ramucirumab treatment after radiological PD.

Abstract
Background Carcinoma of the ampulla of Vater with distant metastases is regarded as unresectable. Systemic chemotherapy is basically the treatment of choice for such tumors. Case presentation A 68-year-old woman was referred to our hospital and diagnosed with carcinoma of the ampulla of Vater with lymph node and multiple liver metastases. She underwent systemic chemotherapy with a combination of gemcitabine and cisplatin. After 19 months of treatment, the primary tumor and liver metastases were difficult to detect on follow-up images. Shrinkage of the enlarged lymph nodes was also confirmed. Surgical resection was performed with curative intent after a multidisciplinary meeting. Pathological examination of the resected specimen showed no residual tumors. Systemic chemotherapy achieved a pathological complete response. The postoperative course was uneventful, and the patient remained free of recurrent disease at 10 months of follow-up. Conclusion This case shows the possibility of conversion surgery after systemic chemotherapy for carcinoma of the ampulla of Vater.

Abstract
BACKGROUND Little evidence exists regarding long-term survival after microwave ablation for hepatocellular carcinoma (HCC). The aim of this study is to determine actual 10-year survival and clarify the clinicopathological features of patients surviving ≥ 10 years after surgical microwave ablation. PATIENTS AND METHODS This retrospective study identified 459 patients who underwent surgical microwave ablation for HCC with curative intent between 2001 and 2008. We compared 100 patients who survived ≥ 10 years with 321 patients who died within 10 years. RESULTS Median overall survival and recurrence-free survival rates were 5.5 and 2.4 years, respectively. The actual 10-year overall survival rate was 23.8%, and the actual 10-year recurrence-free survival rate was 8.1%. Multivariate analysis showed that age > 70 years [odds ratio 1.87, P = 0.029], hepatitis C virus positivity (OR 2.30, P = 0.004), Child-Pugh class B (OR 3.28, P = 0.003), and platelet count < 10 × 104 /µL (OR 1.93, P = 0.033) were independent risk factors for actual 10-year survival. During 10-year follow-up, 66% of the ≥ 10-year survivors developed recurrence, and 91% of these patients underwent further curative treatment, including hepatic resection or local ablation, for HCC recurrence. CONCLUSION Ten-year survival after surgical microwave ablation for HCC can be expected in approximately 24% of patients, even though nearly 2/3 of our 10-year survival patients experienced recurrence. Close postoperative follow-up and further curative treatment for recurrence are important for improving long-term survival.

Abstract
The near-Earth carbonaceous asteroid 162173 Ryugu is thought to have been produced from a parent body that contained water ice and organic molecules. The Hayabusa2 spacecraft has obtained global multicolor images of Ryugu. Geomorphological features present include a circum-equatorial ridge, east-west dichotomy, high boulder abundances across the entire surface, and impact craters. Age estimates from the craters indicate a resurfacing age of [Formula: see text] years for the top 1-meter layer. Ryugu is among the darkest known bodies in the Solar System. The high abundance and spectral properties of boulders are consistent with moderately dehydrated materials, analogous to thermally metamorphosed meteorites found on Earth. The general uniformity in color across Ryugu's surface supports partial dehydration due to internal heating of the asteroid's parent body.

Abstract
Background Liver is a common location of colorectal metastasis, but intrabiliary growth of liver metastasis is not well recognized. Furthermore, intrabiliary metastasis that discovered over 10 years after excision has rarely been described. Case presentation An 80-year-old man was admitted due to the presence of a liver mass in segment 5 (S5) concomitant with elevated carcinoembryonic antigen (CEA), and carbohydrate antigen (CA) 19–9. He underwent right hemicolectomy for colon cancer 12 years prior. Enhanced computed tomography (CT) showed dilated bile ducts with periductal enhancement in S5; hence, cholangiocarcinoma was suspected. Upon anterior segmentectomy, we observed that the cut surface of the specimen exhibited a yellowish-white tumor within the bile ducts. Histologically, the tumor formed within the papillary process, extended along the lumen, and replaced the normal bile duct epithelium. Immunohistochemical studies showed that the liver tumor and primary colon cancer were negative for cytokeratin (CK) 7 and positive for CK20 and Caudal-type homeobox transcription factor 2 (CDX-2). In addition, both tumors showed a same KRAS mutation. We diagnosed the liver tumor as liver metastasis recurrence from colon cancer. Conclusion Intrabiliary growth type of metastasis (IGM) is difficult to distinguish from cholangiocarcinoma, and sometimes develops long after surgery; thus, careful examination of a patient’s history is needed in such cases.

Abstract
The T2K experiment measures muon neutrino disappearance and electron neutrino appearance in accelerator-produced neutrino and antineutrino beams. With an exposure of 14.7(7.6)×10^{20} protons on target in the neutrino (antineutrino) mode, 89 ν_{e} candidates and seven anti-ν_{e} candidates are observed, while 67.5 and 9.0 are expected for δ_{CP}=0 and normal mass ordering. The obtained 2σ confidence interval for the CP-violating phase, δ_{CP}, does not include the CP-conserving cases (δ_{CP}=0, π). The best-fit values of other parameters are sin^{2}θ_{23}=0.526_{-0.036}^{+0.032} and Δm_{32}^{2}=2.463_{-0.070}^{+0.071}×10^{-3} eV^{2}/c^{4}.

Abstract
When a medical provider(medical personnel)becomes a medical receiver(patient), does the consciousness about chemotherapy change ? If yes, what is the main reason ? In this study, we conducted a questionnaire on the consciousness of doctors and pharmacologists engaged in chemotherapy for gastric and/or colorectal cancer. The number of questionnaires collected was 83 and 92 for gastric and colorectal cancer, respectively. In adjuvant chemotherapy, 5%and 4%do not want to receive any chemotherapy for gastric and colorectal cancer if they are patients. The main reasons are binding hours, side effects, and no wish for life extension. About 11%and 9%change their consciousness regarding chemotherapy according to whether they are care providers or receivers. The main reasons are medical perspective and their sense of duty. In chemotherapy for advanced cancer, 6% and 5% of gastric and colorectal cancer patients, do not want to receive any chemotherapy. The main reasons are low expectations for being cured, binding hours, and no wish for life extension. Further, 21%and 14%wish to have limited chemotherapy. As regards consciousness on chemotherapy, 26% and 18% reported changes according to whether they are providers or receivers. The main reasons are medical perspective and their sense of duty. As for the purpose of chemotherapy for advanced gastric and colorectal cancer, 96% and 43% answered prolonging life and relief, respectively. The proportion of persons who answered complete cure is statistically higher in colorectal(32%)than in gastric cancer(18%). The most common answer for an adverse event they want to avoid if they are patients is peripheral neuropathy. These results clearly demonstrate that a considerable proportion of medical personnel hold a negative attitude against or are reluctant to receiving chemotherapy, especially for advanced gastric and colorectal cancer. It is of great importance to make use of these results in clinical practice.

Abstract
Background The health utility score in patients with stroke relates to physical, psychological, and various other factors. However, the relationship between the health utility score in patients with stroke and objective physical activity has not been clarified. Objective To clarify the relation between the health utility score and objective physical activity in community-dwelling ambulatory patients with stroke. Design A cross-sectional study. Method Patients who received outpatient consultation from a stroke certified nurse after discharge were recruited. We assessed health-related quality of life with the EuroQoL 5-Dimension 3-Level questionnaire and calculated the health utility score. We measured the daily number of steps taken as the index of objective physical activity using an accelerometer. Results Twenty-two patients (72.7% men, 69.5 years old) were included. The health utility score was 0.78 ± 0.14. The physical activity value as indicated by the number of steps taken was 6276.3 ± 4640.7 steps. The health utility score showed a significant positive correlation with the number of steps taken (r = 0.466, p = 0.029). Conclusions The present study showed that the health utility score correlated significantly with objective physical activity in community-dwelling ambulatory patients with stroke. The more the patients with stroke walked, the higher their health utility score was. Further studies should assess other domains of health-related quality of life to comprehensively verify this relationship.

Abstract
SummaryTo demonstrate whether the intravascular precipitation of fibrinogen is responsible for the toxicity of heparinoid, the relation between the toxicity of heparinoid in vivo and the precipitation of fibrinogen in vitro was investigated, using dextran sulfate of various molecular weights and various heparinoids.1. There are close relationships between the molecular weight of dextran sulfate, its toxicity, and the quantity of fibrinogen precipitated.2. The close relationship between the toxicity and the precipitation of fibrinogen found for dextran sulfate holds good for other heparinoids regardless of their molecular structures.3. Histological findings suggest strongly that the pathological changes produced with dextran sulfate are caused primarily by the intravascular precipitates with occlusion of the capillaries.From these facts, it is concluded that the precipitates of fibrinogen with heparinoid may be the cause or at least the major cause of the toxicity of heparinoid.4. The most suitable molecular weight of dextran sulfate for clinical use was found to be 5,300 ~ 6,700, from the maximum value of the product (LD50 · Anticoagulant activity). This product (LD50 · Anticoagulant activity) can be employed generally to assess the comparative merits of various heparinoids.5. Clinical use of the dextran sulfate prepared on this basis gave satisfactory results. No severe reaction was observed. However, two delayed reactions, alopecia and thrombocytopenia, were observed. These two reactions seem to come from the cause other than intravascular precipitation.
