Abstract
Pulmonary varix is a rare and usually asymptomatic localized dilation of a pulmonary vein. This disease should be distinguished from other pulmonary and mediastinal diseases, particularly pulmonary arteriovenous malformations. Herein, we encountered a case of pulmonary varix clearly demonstrated by 3-dimensional reconstructed computed tomography (3D-CT) which proved useful in its diagnosis. The 3D-CT enabled easy understanding of the vascular connections and confirmation of the absence of an inflow pulmonary artery. We also performed angiography which showed findings consistent with those obtained by the 3D-CT, thus confirming the diagnosis of pulmonary varix. After the diagnosis, the patient was followed up for several years without any treatment and she remained asymptomatic. On follow-up CT, the lesion remained unchanged.

Abstract
Fat accumulation in the liver, pancreas, skeletal muscle, and visceral bed relates to type 2 diabetes (T2D). However, the distribution of fat among these compartments is heterogenous and whether specific distribution patterns indicate high T2D risk is unclear. We therefore investigated fat distribution patterns and their link to future T2D. From 2,168 individuals without diabetes who underwent computed tomography in Japan, this case-cohort study included 658 randomly selected individuals and 146 incident cases of T2D over 6 years of follow-up. Using data-driven analysis (k-means) based on fat content in the liver, pancreas, muscle, and visceral bed, we identified four fat distribution clusters: hepatic steatosis, pancreatic steatosis, trunk myosteatosis, and steatopenia. In comparisons with the steatopenia cluster, the adjusted hazard ratios for incident T2D were 4.02 (95% CI 2.27-7.12) for the hepatic steatosis cluster, 3.38 (1.65-6.91) for the pancreatic steatosis cluster, and 1.95 (1.07-3.54) for the trunk myosteatosis cluster. The clusters were replicated in 319 German individuals without diabetes who underwent MRI and metabolic phenotyping. The distribution of the glucose area under the curve across the four clusters found in Germany was similar to the distribution of T2D risk across the four clusters in Japan. Insulin sensitivity and insulin secretion differed across the four clusters. Thus, we identified patterns of fat distribution with different T2D risks presumably due to differences in insulin sensitivity and insulin secretion.

Abstract
INTRODUCTION With the advent of effective systemic therapy, transarterial chemoembolization (TACE) is established as a highly effective locoregional treatment modality for carefully selected patients with hepatocellular carcinoma (HCC). This randomized controlled trial was conducted to clarify whether selective TACE with drug-eluting beads (DEB-TACE) loaded with epirubicin or selective conventional TACE (cTACE) with epirubicin-ethiodized oil might be more effective for obtaining complete response(CR) in patients with HCC. METHODS Between March 2016 and May 2019, Child-Pugh class A or B patients with unresectable HCC who were scheduled to receive selective TACE were randomly assigned at a 1:1 ratio to the DEB-TACE arm or the cTACE arm. The primary endpoint was the CR rate at 3 months, as evaluated according to the modified Response Evaluation Criteria in Solid Tumors by an independent review committee, and the secondary endpoints were the CR rate at 1 month and incidences of adverse events. RESULTS A total of 200 patients (DEB-TACE, 99 patients; cTACE, 101 patients) were enrolled in the study. The CR rates at 3 months and 1 month were significantly higher in the cTACE arm (75.2%, 84.2%) as compared with the DEB-TACE arm (27.6%, 35.7%). However, the frequencies of adverse events of any grade, including pyrexia (DEB-TACE vs. cTACE, 19.4% vs. 45.5%, p = 0.0001), fatigue (5.1% vs. 15.8%, p = 0.0194), malaise (11.1% vs. 25.7%, p = 0.0103), appetite loss (12.1% vs. 28.7%, p = 0.0048), abdominal pain (12.1% vs. 23.8%, p = 0.0423), increased serum bilirubin (22.2% vs. 48.5%, p = 0.0002), hypoalbuminemia (43.4% vs. 60.3%, p = 0.0154), increased serum aspartate aminotransferase (35.7% vs. 81.2%, p < 0.0001), and increased serum alanine aminotransferase (35.7% vs. 77.2%, p < 0.0001), were also significantly higher in the cTACE arm than in the DEB-TACE arm. CONCLUSIONS Selective cTACE appeared to have higher CR rates for local tumor control as compared to selective DEB-TACE for HCC. However, the frequency of postembolization syndrome was also significantly higher in the cTACE group than in the DEB-TACE group. Thus, to achieve CR, cTACE may be selected over DEB-TACE in patients who can be expected to tolerate postembolization syndrome.

Abstract
UNLABELLED The effect of romosozumab is affected by previous osteoporosis treatment. Here we showed that the duration of the previous treatment just before romosozumab affects the therapeutic effect of romosozumab. Using denosumab and oral bisphosphonates for more than 1 year attenuates the effect of romosozumab. INTRODUCTION As an anti-sclerostin antibody, romosozumab suppresses bone resorption and stimulates bone formation. We investigated whether the effectiveness of 12 months of romosozumab treatment depended on the duration of previous treatment with teriparatide, denosumab, or oral bisphosphonates. METHODS In total, 259 osteoporosis patients received subcutaneous injections of romosozumab (210 mg) every 4 weeks during 2019 and 2020. This study was designed as a pre-post comparison. The end points were the percent changes of bone mineral density (BMD) after 12 months of romosozumab treatment. The patients were divided into seven groups depending on the type and duration of previous treatment before starting romosozumab as follows: non-previous treatment group, change from teriparatide used for 1 year or less/more than 1 year, change from denosumab used for 1 year or less/more than 1 year, and change from oral bisphosphonates used for 1 year or less/more than 1 year. RESULTS The effects of previous treatment with teriparatide on the effectiveness of 12-month romosozumab did not clearly depend on the duration of treatment (p > 0.05). In contrast, the effects of previous treatments with denosumab or oral bisphosphonates on the effectiveness of 12-month romosozumab depended on the previous treatment duration, which was reflected by the differences in percent change of the spine BMD (both p < 0.05), however, there were no significant differences in the percent change of the total hip BMD (both p > 0.05). CONCLUSION The duration of the previous treatment affected the effectiveness of romosozumab. Using denosumab and oral bisphosphonate for more than 1 year attenuated the effect of romosozumab.

Abstract
So far, no studies investigated the association between pharmacist intervention and rehabilitation outcomes. The aim of study was to establish whether the pharmacist-led deprescribing intervention affects rehabilitation outcomes. This retrospective, observational, single-center, cohort study included consecutive geriatric patients (n = 448) with pharmacist-led intervention between 2017 and 2019. Participants were divided based on pharmacist-led deprescribing and non deprescribing interventions during hospitalization. Demographic data, laboratory data, the Functional Independence Measure were (FIM) analyzed between the groups. Multiple linear regression analysis was performed to analyze the relationship between pharmacist-led deprescribing and FIM total gain. The primary outcome was FIM total gain. The rate of pharmacist intervention during the study period was 92.4%. A multiple linear regression analysis of FMI-T gain, adjusting for confounding factors, revealed that the pharmacist-led deprescribing intervention was independently correlated with FMI-T gain. Particularly, the use of dyslipidemia drugs, antipsychotic drugs, hypnotics, and nonsteroidal anti-inflammatory drugs significantly decreased during hospitalization. The pharmacist-led deprescribing intervention was independently and significantly associated with FIM-T gain. The pharmacist-led deprescribing intervention improved functional recovery in a rehabilitation setting.

Abstract
Background Replaced right hepatic artery (rRHA) is a common vascular variation, and combined resection of this vessel is sometimes needed for the curative resection of pancreatic head malignancy. Safe surgical management has not been established, and there is a small number of reported cases. Here, we reported five cases, wherein preoperative embolization of rRHA was performed for combined resection. Case presentation All patients had pancreatic head malignancies that were in contact with rRHA. We performed a preoperative embolization of the rRHA before the scheduled pancreaticoduodenectomy for the combined resection. Arterial embolization was safely accomplished, and the communicating arcade from the left hepatic artery via the hilar plate was clearly revealed in all cases. Four patients underwent the operative procedure, except for one patient who had liver metastasis at laparotomy. No patient suffered from a severe abnormal liver function during the management; however, one patient had multiple liver infarctions during the postoperative course. Conclusions Preoperative embolization for the combined resection of rRHA in pancreaticoduodenectomy can be a management option for the precise evaluation of hemodynamics after sacrificing rRHA. In our cases, arterial flow to the right liver lobe was supplied by the left hepatic artery via the bypass route, including the communicating arcade of the hilar plate.

Abstract
Adrenocortical carcinoma (ACC) is a rare malignant tumor with a poor prognosis. Local recurrence or distant metastases occur in more than 50% of cases. Patients with metastases have limited treatment options, and <15% have a 5-year survival time. Herein, we describe a 44-year-old woman with ACC and who underwent retroperitoneal tumor resection. Multiple liver and lung metastases were found 1-year postresection. Mitotane therapy started as systemic treatment. Lung metastases were controlled but liver metastases were progressive. The liver metastases were treated by performing 2 resections and 6 bland transarterial embolization (bland TAE), and are presently controlled with only 2 liver metastases of <20 mm. The present case showed that bland TAE can achieve long-term prevention of the progression of liver metastases of ACC. The ultraselective bland TAE for selective embolization supported by the latest computed tomography analysis techniques during arteriography could minimize liver damage caused by embolization and allowed multiple treatments which prolonged survival. We conclude that bland TAE can be effective for controlling liver metastases of ACC.

Abstract
Background and Aim With the control of viral hepatitis, alcoholic hepatocellular carcinoma (HCC) is becoming increasingly important in Japan. In alcoholic cirrhosis, the impact of portal hypertension is significant. Thus, it may be difficult to predict prognosis accurately with the reported prognostic scores. Here we propose the platelet‐albumin‐bilirubin tumor nodes metastasis (TNM) score (PALBI‐T score) as a prognostic model for HCC in alcoholic liver disease, and investigate its usefulness. The PALBI‐T score is an integrated score based on the TNM stage and PALBI grade including platelets, reflecting portal hypertension. Methods This study included 163 patients with alcoholic HCC treated at our Center from 1997 to 2018. We compared the prognostic prediction abilities of the Japan Integrated Staging (JIS) score, ALBI‐T score, and PALBI‐T score. The PALBI‐T score was calculated similarly to the JIS and ALBI‐T scores. Areas under the receiver operating characteristic curve (AUC) were calculated for predicting overall survival (OS). Results In predicting the 1‐year survival, the JIS score had a larger AUC (AUC = 0.925) than the ALBI‐T score (AUC = 0.895) and PALBI‐T score (AUC = 0.891). On the other hand, there was no significant difference in predicting OS among the integrated scores. The PALBI‐T score (AUC = 0.740) had the largest AUC, and the JIS score (AUC = 0.729) and ALBI‐T score (AUC = 0.717) were not significantly different from the PALBI grade (AUC = 0.634). The PALBI grade reflected the degree of portal hypertension. Conclusion In patients with alcoholic HCC, the Japan Integrated Staging score is useful for predicting short‐term prognosis. The PALBI‐T score, which reflects portal hypertension, appears to be a more valid prognostic score for predicting long‐term prognosis.

Abstract
OBJECTIVES This study aimed to assess the frequencies of the anterior spinal arteries identified by CT during arteriography (CTA) and arteriography alone. METHODS This retrospective study included 137 vessels in 83 patients who performed both bronchial arteriography and CTA and categorized them into three groups based on the catheter tip locations: intercostobronchial trunk (ICBT), bronchial artery (BA), and intercostal artery (ICA). The frequencies of anterior spinal artery identified by CTA and arteriography alone were compared for each group. RESULTS ICBT, BA, and ICA groups were evaluated by CTA in 46, 79, and 12 vessels, respectively. By CTA evaluation, anterior spinal artery was identified in seven vessels (15.2%) in ICBT group, 0 in BA group and two (16.7%) in ICA group. The frequencies of anterior spinal artery were significantly higher (p < 0.05) in ICBT and ICA groups than in BA group. By arteriography evaluation alone, a faint anterior spinal artery was identified in two vessels (4.3%) in ICBT group, 0 in BA group, and 1 (8.3%) in ICA group. CONCLUSIONS Anterior spinal artery branched only from the ICBT or ICA and not from the BA in both arteriography and CTA assessments. There was high false-negative rate (71%) of the anterior spinal artery by ICBT arteriography alone assessment compared to CTA assessment. This result explains one of the reasons that spinal ischemia occurs in arteriography-negative spinal artery cases. ADVANCES IN KNOWLEDGE False-negative rate of anterior spinal artery was 71% (5/7) by intercostobronchial trunk arteriography alone assessment.

Abstract
BACKGROUND Retropharyngeal hematoma can cause suffocation if there is delay in securing the airway by intubation. However, there are also concerns about complications that can arise with intubation; it is still unknown which cases do not require intubation. CASE PRESENTATION An 88-year-old woman slipped and was found prone and was transported to the emergency room. She was alert without any stridor. Physical examination revealed a subcutaneous hematoma in the anterior cervical region. Computed tomography revealed a retropharyngeal hematoma. Angiography and computed tomography angiography showed extravasation from the right costocervical trunk. A radiologist performed trans-arterial embolization, and she had an uneventful course without intubation or developing any complication. She became ambulatory on postoperative day 5. CONCLUSION Angiography and computed tomography angiography help in early recognition of extravasation in retropharyngeal hematoma, and trans-arterial embolization can help to avoid intubation and its complications.

Abstract
BACKGROUND Only a few studies have longitudinally evaluated whether fatty pancreas increases the risk of type-2 diabetes (T2D), and their results were inconsistent. Fatty pancreas is closely linked to overweight and obesity, but previous studies did not exclude overweight or obese individuals. Therefore, in this cohort study, we investigated the association between fatty pancreas and T2D incidence in lean individuals. METHODS Between 2008 and 2013, 1478 nondiabetic lean individuals (i.e. body-mass index < 25 kg/m2) underwent health examinations including computed tomography (CT) and were followed for a median of 6.19 years. Fatty pancreas was evaluated by a histologically-validated method using pancreas attenuation (Hounsfield units [HU]) on CT at baseline; lower pancreas attenuation indicates more pancreatic fat. To detect incident T2D, we used fasting plasma glucose, HbA1c, and self-reports of prescribed anti-diabetes medications. Odds ratios (OR) for the association between pancreas attenuation and incident T2D were estimated using logistic regression models adjusted for likely confounders. RESULTS T2D occurred in 61 participants (4.13%) during the follow-up period. Lower pancreas attenuation (i.e. more pancreatic fat) at baseline was associated with incident T2D (unadjusted OR per 10 HU lower attenuation: 1.56 [95% CI 1.28-1.91], p < 0.001). The multivariable-adjusted analysis revealed a similar association (adjusted OR per 10 HU lower attenuation: 1.32 [95% CI 1.06-1.63], p = 0.012). CONCLUSIONS T2D was likely to develop in lean individuals with the fatty pancreas. Among people who are neither obese nor overweight, the fatty pancreas can be used to define a group at high risk for T2D.

Abstract
4518 Background: Transarterial chemoembolization (TACE) with selective catheterization into the segmental or subsegmental hepatic arteries supplying HCC is often performed to achieve the complete local control of HCC in the patients with a limited number of small sized nodules. To clarify which of TACE with drug-eluting beads loaded with epirubicin (DEB-TACE) or conventional TACE with epirubicin-lipiodol (cTACE) can achieve the complete response (CR) more frequently, we performed a randomized controlled trial of DEB-TACE vs. cTACE. Methods: Between March 2016 and May 2019, unresectable HCC patients with Child-Pugh class A or B who were scheduled to receive selective TACE were randomly assigned 1:1 to the DEB-TACE group and the cTACE group. The primary endpoint was the CR rate at 3 months, and the secondary endpoints were the CR rate at 1 month and rate of adverse events (AEs). The response and AEs were assessed according to the modified RECIST by an independent review committee and the National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0., respectively. Results: A total of 200 patients (DEB-TACE, 99 patients; cTACE 101 patients) were enrolled from 22 Japanese institutions. The patient characteristics were well-balanced between the two groups. The median number of tumors was one in both groups and the median tumor size was 20.0 mm in the DEB-TACE group and 20.5 mm in the cTACE group. The table shows the CR rates and frequencies of AEs. The CR rates of cTACE at 3 and 1 months were significantly higher than those of DEB-TACE. The frequency of AEs (all grades), including pyrexia, malaise, increased serum total bilirubin (T-Bil) and increased serum alanine transaminase (ALT), was significantly higher in the cTACE group than in the DEB-TACE group. Conclusions: Selective cTACE appeared to have greater efficacy for local tumor control as compared to selective DEB-TACE, however, the frequencies of post-embolization syndromes were higher in the cTACE group than in the DEB-TACE group.

Abstract
Spinal cord ischemia is an important complication of bronchial artery embolization for hemoptysis. It has been reported even though a spinal artery was not visualized on arteriography. We could show a 67-year-old man with repeated hemoptysis. His hemoptysis gradually worsened and diagnosed with severe hemoptysis, and transarterial embolization was planned to stop the hemoptysis. An anterior spinal artery arising from intercostobronchial trunk confirmed by computed tomography during arteriography even though it was not visualized on arteriography. Great care should be taken with transarterial embolization via intercostobronchial trunk, potentially branching the spinal artery, even though it was not visualized on arteriography alone.

Abstract
AIM To evaluate the association between 11C-methionine positron-emission tomography (11C-methionine PET) findings, isocitrate dehydrogenase (IDH) gene mutation, and O6-methylguanine-DNA methyltransferase (MGMT) promoter methylation in patients with grade II and III gliomas. MATERIALS AND METHODS Data were collected from 40 patients with grade II and III gliomas who underwent both magnetic resonance imaging (MRI) and 11C-methionine PET as part of their pre-surgical examination. IDH mutation was examined via DNA sequencing, and MGMT promoter methylation via quantitative methylation-specific polymerase chain reaction (PCR). RESULTS A threshold of MGMT promoter methylation of 1% was significantly associated with tumour/normal tissue (T/N) ratio. The T/N ratio in samples with MGMT promoter methylation ≥1% was higher than that in samples with MGMT promoter methylation <1%, and the difference was statistically significant (p=0.011). Reliable prediction of MGMT promoter methylation (<1% versus ≥1%) was possible using the T/N ratio under the receiver operator characteristic (ROC) curve with a sensitivity and specificity of 75% each (cut-off value=1.6: p=0.0226, area under the ROC curve [AUC]=0.76172). Conversely, the T/N ratio had no association with IDH mutation (p=0.6). The ROC curve revealed no reliable prediction of IDH mutation using the T/N ratio (p=0.606, AUC=0.60577). CONCLUSION 11C-methionine PET parameters can predict MGMT promoter methylation but not IDH mutation status. 11C-methionine uptake may have limited potential to reflect DNA methylation processes in grade II and III gliomas.

Abstract
BACKGROUND Total pancreatectomy is required to completely clear tumours that are locally advanced or located in the centre of the pancreas. However, reports describing clinical outcomes after total pancreatectomy are rare. The aim of this retrospective observational study was to assess clinical outcomes following total pancreatectomy using a nationwide registry and to create a risk model for severe postoperative complications. METHODS Patients who underwent total pancreatectomy from 2013 to 2017, and who were recorded in the Japan Society of Gastroenterological Surgery and Japanese Society of Hepato-Biliary-Pancreatic Surgery database, were included. Severe complications at 30 days were defined as those with a Clavien-Dindo grade III needing reoperation, or grade IV-V. Occurrence of severe complications was modelled using data from patients treated from 2013 to 2016, and the accuracy of the model tested among patients from 2017 using c-statistics and a calibration plot. RESULTS A total of 2167 patients undergoing total pancreatectomy were included. Postoperative 30-day and in-hospital mortality rates were 1·0 per cent (22 of 2167 patients) and 2·7 per cent (58 of 167) respectively, and severe complications developed in 6·0 per cent (131 of 2167). Factors showing a strong positive association with outcome in this risk model were the ASA performance status grade and combined arterial resection. In the test cohort, the c-statistic of the model was 0·70 (95 per cent c.i. 0·59 to 0·81). CONCLUSION The risk model may be used to predict severe complications after total pancreatectomy.

Abstract
The bioactivity of anodized near-β TiNbSn alloy with low Young's modulus prepared in sulfuric acid electrolytes was examined to explore the osseointegration mechanism with a focus on the role of anodic oxide. Hydroxyapatite (HA) precipitated on the surface of anodic oxide following immersion in Hank's solution, and precipitation accelerated with increase in the sulfuric acid concentration of the electrolyte. HA is formed on the surface of as-anodized oxide without subsequent annealing or hot water (HW) treatment. This outcome differs from that of a previous study using anodized TiNbSn alloy prepared in acetic acid electrolytes requiring for subsequent HW treatment. It was found that the oxide anodized in sulfuric acid electrolyte contains a large amount of internal pores and is highly crystallized thick TiO2, whereas the same prepared in the acetic acid electrolyte is low crystalline thin TiO2 containing a small amount of pores. The present anodized TiNbSn alloy is preferred for maintaining the low Young's modulus of the alloy and eliminating the subsequent treatment to increase the Young's modulus. A model to rationalize the bioactivity of the present anodic oxide is proposed based on the series of studies. It is concluded that the sulfuric acid electrolyte is favorable for both HA formation and low Young's modulus, and the bioactivity is attributed to the anodic TiO2 that facilitates incorporation of bone ingredients.

Abstract
BACKGROUND AND AIM Previous cross-sectional studies showed that pancreatic fat was associated with metabolic syndrome. However, no longitudinal study has evaluated whether people with high pancreatic fat are likely to develop future metabolic syndrome. This study investigated the association between baseline pancreatic fat and metabolic syndrome incidence. METHODS In 2008-2009, 320 participants without metabolic syndrome underwent health checks, which included unenhanced computed tomography, and were followed up annually for 4-5 years. Baseline pancreatic fat amounts were evaluated using a histologically validated method that measured differences between pancreas and spleen attenuations on computed tomography. The participants were divided into low (reference), intermediate, and high pancreatic fat groups based on pancreas and spleen attenuation tertiles. Metabolic syndrome incidence was evaluated annually over a median follow-up period of 4.99 (interquartile range, 4.88-5.05) years, in accordance with the 2009 harmonized criteria. Risk ratios (RRs) for the association between baseline pancreatic fat amounts and metabolic syndrome incidence were estimated using Poisson regression models adjusted for age, sex, body mass index, liver fat, pre-metabolic syndrome, cigarette use, alcohol use, and physical activity. RESULTS Metabolic syndrome incidence was 30.6% (98/320). Pancreatic fat was associated with an increased incidence of metabolic syndrome, based on a univariate analysis (RRs [95% confidence interval], 3.14 [1.74-5.67] and 3.96 [2.23-7.03] in the intermediate and high pancreatic fat groups, respectively). The association remained statistically significant in the multivariate analysis (RR [95% confidence interval], 2.04 [1.14-3.64] and 2.30 [1.28-4.14] for the same groups, respectively). CONCLUSIONS Pancreatic fat predicts the future risk of metabolic syndrome.

Abstract
PURPOSE To evaluate safety and efficacy of combining sorafenib with transarterial chemoembolization in patients with advanced stage hepatocellular carcinomas (HCCs). MATERIALS AND METHODS Systemic chemotherapy-naïve patients with a Child-Pugh class A liver profile and advanced stage HCCs were enrolled. Sorafenib therapy (daily dose 800 mg) was initiated within 4 weeks after initial conventional transarterial chemoembolization with an allowance of subsequent on-demand conventional chemoembolization. The primary endpoint was rate of protocol treatment completion, which was defined as sorafenib administration for at least 2 months. Secondary endpoints included objective response rate, disease control rate, overall survival, progression-free survival, and incidence of adverse events. Thirty-one patients (24 men, 7 women; median age, 75 years; vascular invasion, n = 19; extrahepatic metastases, n = 18; both, n = 6) who met the inclusion criteria were enrolled. RESULTS Protocol treatment was completed in 28 patients (90.3%, 28/31) with median protocol treatment duration of 7.0 months (range, 0.5-30 months) and median of 2 (range, 1-4) transarterial chemoembolization sessions. Objective response rate was 77.4% with median overall and progression-free survival of 17.3 months (95% confidence interval, 11.9-22.6 months) and 5.4 months (95% confidence interval, 4.6-6.2 months), respectively. The most common grade 3 or 4 adverse events were self-limiting elevation of aspartate aminotransferase (54.8%, 17/31) and alanine aminotransferase (45.2%, 14/31). CONCLUSIONS This combination therapy is feasible and promising in patients with advanced stage HCCs.

Abstract
PURPOSE A prospective multicenter phase I/II trial was performed to evaluate the clinical safety and efficacy of radiofrequency ablation (RFA) for metastatic bone tumors. MATERIALS AND METHODS Thirty-three patients (27 men, 6 women, mean age 61 years) with metastatic bone tumors were enrolled. In phase I, nine patients were enrolled, and the safety of RFA was evaluated. In phase II, 23 patients were included, and an intent-to-treat analysis was performed. The primary endpoint was to evaluate the treatment's safety. The secondary endpoint was to evaluate the efficacy of pain relief at 1 week after RFA. RESULTS RFA was performed in 32 of 33 enrolled patients. No serious complications were observed during the phase I, so phase II was performed. Four patients exhibited adverse events, including one case each of Grade 3 pain and, Grade 2 hypotension, and one patient developed Grade 1 burns at the grounding pad and puncture site. One patient died of liver failure on day 7 after RFA due to the progression of the primary lesion. The efficacy was excellent (no increase in analgesic dosage, post-RFA VAS score of 0-2 or decreased by not less than 5 compared to before RFA) in 20 patients (60.6%), good (no increase in analgesic dosage, post-RFA VAS score decreased by not less than 2 but by < 5 compared to before RFA) in 3 (9.1%), and poor in 10 patients (30.3%). Thus, the response rate was 69.7%. CONCLUSION RFA is a safe and effective method for treating painful metastatic bone tumors.

Abstract
INTRODUCTION Medial meniscus posterior root tear (MMPRT) leads to abnormal biomechanics of the knee by inducing the medial meniscus extrusion (MME). However, a time-dependent increase of the MME is not fully elucidated in patients suffering from the acute MMPRT. The aim of this study was to investigate the relationships among disease duration of the MMPRT and severity of the MME. We hypothesized that MME measurement correlates with disease duration after a sudden onset of the minor traumatic MMPRT during the short-term follow-up period. MATERIALS AND METHODS Forty-six patients who had an accurate episode of the posteromedial painful popping were investigated. All the patients were diagnosed having a symptomatic MMPRT with magnetic resonance imaging (MRI) examinations. Absolute MME was measured using MRI scans within 12 months after painful popping events. A correlation coefficient between duration from injury to MRI examination and absolute MME was evaluated. RESULTS Mean absolute MME was 4.5±1.6mm (range, 1.1-8.8mm) on MRI measurements. A good correlation was observed between MME measurement and duration from injury to MRI examination (R2=0.612). The best-fit equation for predicting each value was: MME=0.014×disease duration+3.288mm. DISCUSSION This study demonstrated that absolute MME increases progressively within the short duration after the onset of symptomatic MMPRT. Our results suggest that preoperative MME assessment may be important in determining disease duration and treatment strategy of the MMPRT. LEVEL OF EVIDENCE Retrospective cohort study level IV.

Abstract
Abstract
We fabricated polymer blends of recycled-PC (PC) and recycled-PET (PET) using high-shear processing technology. We also assessed its structure, morphology, and physical properties. Results of DSC measurements show that Tg of PC and Tc of PET shifted to higher temperatures by kneading under high-shear conditions. Results show further that the Tm of PET shifted to a lower temperature. Moreover, compatibilization progressed. TEM observations show that the PET domain was not confirmed completely under the kneading condition of 1 000 min−1/10 s or more. Compatibilization progressed. Tensile test results show that the PET ratio of 30 wt% (1 000 min−1/10 s) has higher breaking strain than neat PC does. Chemical resistance test results obtained by good solvent of PC demonstrated that blending of PET makes PC elution difficult.

Abstract
e15648 Background: Sorafenib has been acknowledged as a standard treatment for advanced stage hepatocellular carcinoma (HCC). This study was conducted to evaluate the safety and efficacy of combination therapy of sorafenib and on-demand transarterial chemoembolization (TACE) for advanced stage HCC. Methods: Inclusion criteria were advanced stage HCC (Barcelona Clinic Liver Cancer stage C), a systemic chemotherapy native status, an Eastern Cooperative Oncology Group performance status 0–1, and a Child-Pugh grade-A. Sorafenib therapy (800 mg daily) was started 4–28 days after TACE. On-demand TACE was allowed. The primary endpoint was the completion rate of protocol treatment, which was defined as sorafenib administration at least for 2 months from initial TACE. Secondary endpoints were objective response rate (ORR), disease control rate (DCR) based on modified Response Evaluation Criteria in Solid Tumors, overall survival (OS), progression-free survival (PFS), and the incidence of adverse events. Results: From July 2013 to September 2015, a total of 32 patients were registered from 9 institutions, but one patient was excluded because his tumor turned out to be combined hepatocellular carcinoma and cholangiocarcinoma. The protocol treatment was completed in 28 of 31 enrolled patients (90.3%, 28/31). The median treatment duration was 7.0 months (range 0.5–30) with the median number of TACE was 1 (range 1–4) and the median sorafenib dosage of 400 mg daily (range 154-800). The ORR and DCR were 77% and 90%, respectively. Median OS and PFS were 17.3 months [95% confidence interval (CI), 11.9–22.6] and 5.4 months (95% CI, 4.6–6.2), respectively. The most common grade-3 or -4 adverse events were increased aspartate aminotransferase (55%, 17/31), increased alanine aminotransferase (45% 14/31), and hypertension (23%, 7/31). Conclusions: Combination therapy of sorafenib and on-demand TACE was well tolerated and safe. Furthermore, this combination treatment may provide a survival benefit to patients with advanced stage HCC. Clinical trial information: UMIN000014213.

Abstract
INTRODUCTION Injuries to the medial meniscus (MM) posterior root lead to accelerated cartilage degeneration of the knee. An anatomic placement of the MM posterior root attachment is considered to be critical in transtibial pullout repair of the medial meniscus posterior root tear (MMPRT). However, tibial tunnel creation at the anatomic attachment of the MM posterior root is technically difficult using a conventional aiming device. The aim of this study was to compare two aiming guides. We hypothesized that a newly-developed guide, specifically designed, creates the tibial tunnel at an adequate position rather than a conventional device. MATERIALS AND METHODS Twenty-six patients underwent transtibial pullout repairs. Tibial tunnel creation was performed using the Multi-use guide (8 cases) or the PRT guide that had a narrow twisting/curving shape (18 cases). Three-dimensional computed tomography images of the tibial surface were evaluated using the Tsukada's measurement method postoperatively. Expected anatomic center of the MM posterior root attachment and tibial tunnel center were evaluated using the percentage-based posterolateral location on the tibial surface. Percentage distance between anatomic center and tunnel center was calculated. RESULTS Anatomic center of the MM posterior root footprint located at a position of 78.5% posterior and 39.4% lateral. Both tunnels were anteromedial but tibial tunnel center located at a more favorable position in the PRT group: percentage distance was significantly smaller in the PRT guide group (8.7%) than in the Multi-use guide group (13.1%). DISCUSSION The PRT guide may have great advantage to achieve a more anatomic location of the tibial tunnel in MMPRT pullout repair. LEVEL OF EVIDENCE III.

Abstract
Individual dose estimates calculated by Dosimetry System 2002 (DS02) for the Life Span Study (LSS) of atomic bomb survivors are based on input data that specify location and shielding at the time of the bombing (ATB). A multi-year effort to improve information on survivors' locations ATB has recently been completed, along with comprehensive improvements in their terrain shielding input data and several improvements to computational algorithms used in combination with DS02 at RERF. Improvements began with a thorough review and prioritization of original questionnaire data on location and shielding that were taken from survivors or their proxies in the period 1949-1963. Related source documents varied in level of detail, from relatively simple lists to carefully-constructed technical drawings of structural and other shielding and surrounding neighborhoods. Systematic errors were reduced in this work by restoring the original precision of map coordinates that had been truncated due to limitations in early data processing equipment and by correcting distortions in the old (WWII-era) maps originally used to specify survivors' positions, among other improvements. Distortion errors were corrected by aligning the old maps and neighborhood drawings to orthophotographic mosaics of the cities that were newly constructed from pre-bombing aerial photographs. Random errors that were reduced included simple transcription errors and mistakes in identifying survivors' locations on the old maps. Terrain shielding input data that had been originally estimated for limited groups of survivors using older methods and data sources were completely re-estimated for all survivors using new digital terrain elevation data. Improvements to algorithms included a fix to an error in the DS02 code for coupling house and terrain shielding, a correction for elevation at the survivor's location in calculating angles to the horizon used for terrain shielding input, an improved method for truncating high dose estimates to 4 Gy to reduce the effect of dose error, and improved methods for calculating averaged shielding transmission factors that are used to calculate doses for survivors without detailed shielding input data. Input data changes are summarized and described here in some detail, along with the resulting changes in dose estimates and a simple description of changes in risk estimates for solid cancer mortality. This and future RERF publications will refer to the new dose estimates described herein as "DS02R1 doses."

Abstract
A medial meniscus posterior root tear (MMPRT) may increase the tibiofemoral contact pressure by decreasing the tibiofemoral contact area. Meniscal dysfunction induced by posterior root injury may lead to the development of osteoarthritic knees. Repair of a MMPRT can restore medial meniscus (MM) function and prevent knee osteoarthritis progression. Several surgical procedures have been reported for treating a MMPRT. However, these procedures are associated with several technical difficulties. Here, we describe a technique to stabilize a torn MM posterior root using the FasT-Fix® all-inside meniscal suture device and a new aiming device. The uncut free-end of the FasT-Fix® suture can be used as a thread for transtibial pullout repair. Our procedure might help overcome the technical difficulties in arthroscopic treatment of a MMPRT.

Abstract
OBJECTIVE Previous cross-sectional studies have shown that attenuation in the pancreas seen on unenhanced computed tomography (CT) scans was inversely correlated with histologic pancreatic fat, and that fatty pancreas was associated with type 2 diabetes mellitus (T2DM). However, no longitudinal study has evaluated whether fatty pancreas increases the incidence of T2DM. We conducted a cohort study to investigate the association between fatty pancreas and the incidence of T2DM. RESEARCH DESIGN AND METHODS A total of 813 participants without diabetes underwent health checks by unenhanced CT scanning in 2008 and 2009, and were observed for a median follow-up period of 5.06 (interquartile range 3.01-5.92) years. Attenuation in three regions of the pancreas seen on an unenhanced CT scan was measured, and the mean pancreatic attenuation was calculated to evaluate fatty pancreas at baseline; the more severe the fatty pancreas, the lower the mean pancreatic attenuation. The incident T2DM hazard ratios (HRs) for the association between fatty pancreas and T2DM incidence were estimated by Cox proportional hazards models adjusted for age, sex, BMI, liver attenuation seen on unenhanced CT scan, and alcohol intake of ≥20 g/day. RESULTS T2DM occurred in 62 participants (7.6%) during the follow-up period. The higher pancreas attenuation (i.e., less pancreatic fat) at baseline was associated with decreased T2DM incidence in a univariate analysis (crude HR 0.97 [95% CI 0.96-0.99]); and fatty pancreas (lower pancreas attenuation) was positively associated with increased T2DM incidence. However, the association was substantially explained by the confounders (multivariate HR 1.00 [95% CI 0.98-1.02]). CONCLUSIONS Fatty pancreas was not independently associated with future T2DM.

Abstract
While it is generally believed that fetuses are at high risk of developing cancers, including leukemia, after low doses of radiation, it has been reported that atomic bomb survivors exposed in utero did not show a dose response for translocations in blood T lymphocytes when they were examined at approximately 40 years of age. Subsequent mouse studies confirmed that animals irradiated during the fetal stage did not show evidence of radiation effects in lymphocytes and bone marrow cells when they were examined after reaching adulthood. However, in a study of rat mammary epithelial cells, radiation effects were clearly observed after fetal irradiation. These results indicate that the fate of chromosome aberrations induced in a fetus could vary among different tissues. Here we report on translocation frequencies in mouse thyroid cells, which were irradiated at different stages of fetal development. Cytogenetic examination was conducted using fluorescence n situ hybridization (FISH) painting of chromosomes 1 and 3. Adult mice, 2 Gy X-ray irradiated at 15.5-day-old fetuses (E15.5), showed a higher translocation frequency (30/1,155 or 25.3 × 10-3) than nonirradiated adult controls (0/1,007 or 0.1 × 10-3), and was near that experienced by irradiated mothers and non-pregnant adult females (43/1,244 or 33.7 × 10-3). These results are consistent with those seen in rat mammary cells. However, when fetuses were irradiated at an earlier stage of development (E6.5) before thyroid organogenesis, the resulting observed translocation frequency was much lower (3/502 or 5.8 × 10-3) than that in E15.5 mice. These results suggest that after fetal irradiation, tissue stem cells record radiation effects primarily when the exposure occurs in cells that have been integrated into tissue. Embryonic stem cells that have been damaged prior to integration into the niche may undergo negative selection due to apoptosis, mitotic death or stem cell-niche cell interactions. The implications of these results in interpreting cancer risks after fetal irradiation are also discussed.

Recent studies revealed that a substantial proportion of patients with high-risk B-cell precursor acute lymphoblastic leukemia (BCP-ALL) harbor fusions involving tyrosine kinase and cytokine receptors, such as ABL1, PDGFRB, JAK2 and CRLF2, which are targeted by tyrosine kinase inhibitors (TKIs). In the present study, transcriptome analysis or multiplex reverse transcriptase–PCR analysis of 373 BCP-ALL patients without recurrent genetic abnormalities identified 29 patients with kinase fusions. Clinically, male predominance (male/female: 22/7), older age at onset (mean age at onset: 8.8 years) and a high white blood cell count at diagnosis (mean: 94 200/μl) reflected the predominance of National Cancer Institute high-risk (NCI-HR) patients (NCI-standard risk/HR: 8/21). Genetic analysis identified three patients with ABL1 rearrangements, eight with PDGFRB rearrangements, two with JAK2 rearrangements, three with IgH-EPOR and one with NCOR1-LYN. Of the 14 patients with CRLF2 rearrangements, two harbored IgH-EPOR and PDGFRB rearrangements. IKZF1 deletion was present in 16 of the 22 patients. The 5-year event-free and overall survival rates were 48.6±9.7% and 73.5±8.6%, respectively. The outcome was not satisfactory without sophisticated minimal residual disease-based stratification. Furthermore, the efficacy of TKIs combined with conventional chemotherapy without allogeneic hematopoietic stem cell transplantation in this cohort should be determined.

Abstract
Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter 'D-shuttle' for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the terrestrial background radiation level of other regions/countries.

Abstract
Chlorella variabilis strain NC64A is an intracellular photobiont of the ciliate Paramecium bursaria. NC64A was isolated from P. bursaria nearly 50 years ago and was thereafter cultivated outside the host. This study was undertaken to detect changes in its infectivity to P. bursaria and its auxotrophy for growth outside the host induced during long-term cultivation. NC64A can grow in Modified Bold's Basal Medium but not in C medium, whereas another symbiotic Chlorella variabilis strain, 1N, that was recently isolated from the host grew in C medium but not in Modified Bold's Basal Medium. With regards infectivity, NC64A in the logarithmic phase of growth showed low infectivity to alga-removed P. bursaria cells, whereas those in the early stationary phase showed high infectivity of about 30%. Those in the decay phase of growth showed no infectivity. Results show that NC64A has infectivity, but the infection rate depends on their culture age in the growth curve. Furthermore, NC64A that had been re-infected to P. bursaria for more than one year and isolated from the host showed a nearly 100% infection rate, which indicates that NC64A can recover its infectivity by re-infection to P. bursaria. Summary: This study was undertaken to detect changes in infectivity induced during long-term cultivation of Chlorella variabilis to alga-free Paramecium bursaria, and its auxotrophy for growth outside the host.
