Abstract
When excited, the magnetization in a magnet precesses around the field in an anticlockwise manner on a timescale governed by viscous magnetization damping, after which any information carried by the initial actuation seems to be lost. This damping appears to be a fundamental bottleneck for the use of magnets in information processing. However, here we demonstrate the recall of the magnetization-precession phase after times that exceed the damping timescale by two orders of magnitude using dedicated two-colour microwave pump-probe experiments for a Y3Fe5O12 microstructured film. Time-resolved magnetization state tomography confirms the persistent magnetic coherence by revealing a double-exponential decay of magnetization correlation. We attribute persistent magnetic coherence to a feedback effect, that is, coherent coupling of the uniform precession with long-lived excitations at the minima of the spin-wave dispersion relation. Our finding liberates magnetic systems from the strong damping in nanostructures that has limited their use in coherent information storage and processing.

Abstract
INTRODUCTION Pancreatic cysts are frequently observed in patients with von Hippel-Lindau disease (VHL), and they are considered clinically not important. This study aimed to evaluate the association between pancreatic cysts and diabetes mellitus (DM) in patients with VHL. METHODS Among patients who were on a patient list at the VHL Center at Kyoto University Hospital as of December 2022, those who had undergone an upper abdominal magnetic resonance imaging study after 2010 were retrospectively evaluated. The presence or absence of DM and high glycated hemoglobin (HbA1c) levels (>6.0%) were assessed. Patients were divided into two groups: those with DM or high HbA1c levels, and those without DM or high HbA1c levels. The area of the whole pancreas, including the pancreatic cysts and tumors, the area of the pancreatic cysts, and the percentage of pancreatic cysts, calculated by dividing the area of pancreatic cysts by the area of the whole pancreas, were measured on T2-weighted magnetic resonance images and compared between the two groups. RESULTS Thirty-six patients with VHL, comprising 22 men and 14 women, with a mean age of 36.4 years (range, 11-79 years), were identified. Seven patients had DM, and two additional patients had high HbA1c levels. The area of the pancreatic cysts (p = 0.0013) was significantly larger and the percentage of the pancreatic cysts (p = 0.0016) was significantly higher in patients with DM or high HbA1c levels (n = 9) than in patients without DM or high HbA1c levels (n = 27); however, the difference in the area of the whole pancreas was not significant (p = 0.068). CONCLUSION Our findings suggest that patients with VHL who have a large area covered by pancreatic cysts are more likely to have DM than those without.

Abstract
Although transarterial embolization is recognized as a treatment for type 2 endoleaks, it can occasionally be challenging. We report the case of an 86-year-old man who presented with an enlarging thoracoabdominal aortic aneurysm following thoracic endovascular aortic repair. Using a triaxial system with a 1.3-F microcatheter, transarterial embolization of a type 2 endoleak was successfully performed through a long and tortuous arterial route comprising the thoracodorsal and ninth intercostal arteries. The postoperative clinical course was uneventful, and computed tomography obtained six days later showed no endoleak in the thoracoabdominal aortic aneurysm. This case suggests the usefulness of a triaxial system with a 1.3-F microcatheter for transarterial embolization of type 2 endoleaks.

Abstract
INTRODUCTION The natural history of a large hepatic hemangioma is important in determining the treatment strategy. Although several studies have assessed the natural history of hepatic hemangiomas, no study has focused on hepatic hemangiomas measuring >10 cm. The aim of this study was to assess the natural history of hepatic hemangiomas measuring >10 cm by evaluating imaging findings and clinical course. METHODS Computed tomography (CT) and magnetic resonance imaging (MRI) reports at Kyoto University Hospital, Kyoto, Japan, between January 2001 and March 2023 were retrospectively searched to find adult patients with hepatic hemangiomas >10 cm. Patients who were followed up without treatment for over six months were included. The maximum diameter of the hepatic hemangioma was compared between the baseline and the final CT or MRI. The clinical course of the patients was evaluated. RESULTS Twenty-two patients (17 women, five men; median age, 51 years) were identified. The median diameter of hepatic hemangiomas in the baseline study was 114 mm. Two patients had abdominal distention at the time of the baseline imaging, whereas the others were asymptomatic. After follow-up without treatment (the median; 95.5 months), enlargement, no change, shrinkage of hepatic hemangioma was observed in six, 11, and five patients, respectively. The median growth rate of hepatic hemangiomas was 2.5 mm/year. Two patients underwent liver resection for hepatic hemangioma, while the others were followed up without treatment. In four patients, symptoms appeared or worsened. Two patients died: one patient died from prostate cancer progression; the cause of death for the other was not confirmed. CONCLUSION Hepatic hemangiomas show a slow growth rate during follow-up, and shrinkage is occasionally observed. Some patients experience new symptoms or aggravation of symptoms; however, deaths associated with hepatic hemangiomas are uncommon.

Abstract
Percutaneous biliary intervention is widely accepted as an effective and safe treatment for various types of bile duct diseases. We present the case of a 44-year-old woman who developed bile leakage after a living-donor liver transplantation for locally advanced cholangiocarcinoma. A percutaneous drainage tube was placed in the segment 8 bile duct via the blind end of the jejunum. However, the bile leakage was unchanged. Bile leakage from the right posterior hepatic duct was suspected. Using a dual lumen microcatheter, a percutaneous drainage tube was placed in the segment 7 bile duct via the blind end of the jejunum, which reduced the bile leakage. These results suggest that a dual lumen microcatheter is a valuable tool for navigating the biliary tree during difficult percutaneous biliary interventions.

Abstract
PURPOSE/OBJECTIVE(S) Palliative radiotherapy is an effective and commonly used treatment for pain relief in metastatic cancer patients. This study aimed to classify the patients to predict their response to palliative radiotherapy. MATERIALS/METHODS This study used the data from our single-center, prospective observational study (UMIN000044984), which included all patients undergoing palliative radiotherapy for the painful tumor, except for postoperative setting or brain metastases. The eligibility criteria were as follows: (1) numerical rating scale (NRS) was two or more before treatment, and (2) underwent palliative radiotherapy between August 2021 and September 2022. Questionnaires for pain site, NRS, and presence/dose of opioids were obtained before, on the last day of treatment, two weeks later, one month later, three months later, and every three months after that. Patients with severe performance status (PS) were contacted by telephone. Pain response was defined to reduce NRS 2 or more at the treated site without an analgesic increase. The primary outcome was the response rate within three months of the treatment. We used multivariable logistic regression to find the independent prognostic factors for the response based on the following covariates: age, sex, PS, body mass index, NRS, history of radiotherapy, treated site, radiographic features (lytic/sclerotic/mixed), metastatic complication, presence/dose of opioids, bone-modifying agents, radiation dose, type of primary tumor, radiosensitivity, number of metastases, and days from diagnosis to treatment. A classification model was created using significant factors, and response rates were calculated for each class. Statistical significance was defined as P<0.05. RESULTS Among 488 targets of 300 patients registered, 366 targets of 261 patients met the criteria. The median age was 65 years, 44% were female, and PS (0/1/2/3/4) was 6/63/18/9/4%. The major type of tumor was gastrointestinal (32%), lung (19%), and breast (12%). Bone metastases were 75% at treated sites. Opioids were used by 72%, BMA was 27%, and chemotherapy was 50%. Re-irradiation rate was 22%. With a median follow-up of 5.8 months, 113 patients were alive, 129 had died, and 20 were lost follow-up. The average NRS was reduced from 6.1 to 3.1 from pretreatment to 3 months later per evaluable 232 targets, resulting in a pain relief rate of 60%. Opioids use (P<0.001) and re-irradiation (P<0.001) were significant factors of poor response in multivariate analysis. In our classification model, 89 targets were classified as class 1 (no opioids & no irradiation history), 211 were class 2 (other than class 1 and 3), and 66 were class 3 (opioids & re-irradiation), were 75/61/36% (P<0.001) of response rate. The 6-month cumulative pain progression rate was 12/22/32% (P<0.001), respectively. CONCLUSION Palliative radiotherapy is highly effective for patients with painful tumors especially for those without previous irradiation history or use of opioids.

Abstract
BACKGROUND Angioedema is a disorder characterized by edema of the face, lips, tongue, and extremities due to increased vascular permeability. Angioedema of the tongue usually occurs bilaterally, and the incidence of unilateral angioedema of the tongue is rare. This study reports a rare case of unilateral angioedema of the tongue with no identifiable cause and repeated recurrence even after discontinuation of an angiotensin-converting enzyme inhibitor. CASE SUMMARY The patient was a 65-year-old woman with pre-existing hypertension and hyperlipidemia and had been receiving 20 mg/d of lisinopril. She was diagnosed with angioedema due to unilateral swelling of the tongue. No airway obstruction was observed, and the symptoms improved following the administration of 0.3 mg of epinephrine intramuscularly and 125 mg of methylprednisolone intravenously. Although lisinopril was discontinued, unilateral angioedema of the tongue continued to recur every 2-5 mo, with the symptoms improving following the administration of prednisolone and an antihistamine. Daily oral administration of 500 mg of tranexamic acid after dinner prevented the recurrence of angioedema. CONCLUSION Careful monitoring and identification of the underlying mechanism play a crucial role in the treatment of angioedema.

Abstract
Background Insulinomas are the most common functioning pancreatic neuroendocrine neoplasms, and these tumors induce hypoglycemia due to hyperinsulinemia. Hypoglycemia caused by insulinomas can cause seizures, coma or death due to the delayed diagnosis. The only curative treatment is surgical resection. To perform curative surgical resection of insulinomas, preoperative localization is crucial. However, localization of insulinomas is often challenging using conventional imaging methods such as computed tomography (CT) and magnetic resonance imaging. Although endoscopic ultrasound (EUS) fine-needle aspiration and selective arterial calcium stimulation test, which can reflect the endocrine character of the tumor, are performed in such cases, these modalities are invasive and require operator-dependent techniques. Additionally, somatostatin receptor (SSTR)-targeted imaging has a relatively low sensitivity for detecting insulinomas due to its low SSTR type 2 expression. Thus, there is an urgent need for developing a noninvasive diagnostic technique which is specific for detecting insulinomas. Consequently, glucagon-like peptide-1 receptor-targeted imaging has recently emerged and gained a wide interest. Recently, we have developed a novel 18F-labeled exendin-4-based probe conjugated with polyethylene glycol, [18F]FB(ePEG12)12-exendin-4 (18F-exendin-4), for positron emission tomography (PET) imaging. Here we report a case of insulinoma in which 18F-exendin-4 PET/CT noninvasively provided critical information for localization. Case description This is a case of a 58-year-old male with symptomatic hypoglycemia for 10 years; however, a preoperative diagnosis of insulinoma was not established due to the difficulty in differentiating it from an accessory spleen using conventional imaging. Moreover, the patient requested to avoid invasive diagnostic procedures including EUS. 18F-exendin-4 PET/CT revealed significant uptakes in the pancreatic tail whereas no apparent uptakes were observed in the spleen; thus, curative laparoscopic enucleation of the pancreatic tail was performed. The diagnosis of insulinoma was confirmed via histopathological examination. This is the first case report of insulinoma diagnosed using 18F-exendin-4 PET/CT. Conclusion In this case, PET information led to curative resection through enucleation of the pancreas. 18F-exendin-4 PET/CT may serve as a useful noninvasive clinical tool for insulinoma localization.

Abstract
OBJECTIVE To evaluate the effectiveness and safety of transcatheter arterial embolization (TAE) of the branches of the subclavian and axillary arteries for hemorrhage control. METHODS Between January 2015 and June 2022, 35 TAE procedures were performed for hemorrhage from the branches of the subclavian and axillary arteries in 34 patients (22 men, 12 women; 1 male underwent TAE twice; mean age = 76 years). Pre-TAE CT showed hematomas in the chest (n = 25) and abdominal walls (n = 3), shoulder (n = 2), and lower neck (n = 2). CT showed hemothorax in eight cases. Angiographic findings, embolization technique, and technical and clinical success of TAE were retrospectively assessed in all cases. RESULTS TAE was performed by transfemoral (n = 16), transradial (n = 12), and transbrachial (n = 7) approaches. Angiography revealed contrast media extravasation or pseudoaneurysms in 32 cases (91.4%). The most commonly embolized arteries were the internal thoracic (n = 12), lateral thoracic (n = 6), and thoracoacromial (n = 6) arteries. Technical and clinical success rates were 100 and 85.7%, respectively. A complication (skin necrosis after injection of the liquid embolic agent) developed in only one patient (2.9%) and was conservatively managed. CONCLUSION TAE is an effective and safe treatment for hemorrhage from the branches of the subclavian and axillary arteries. ADVANCES IN KNOWLEDGE Transfemoral approach has been used for TAE of the branches of the subclavian and axillary artery. Transradial and transbrachial approaches can also be considered.

Abstract
BACKGROUND Primary hepatic extranodal marginal zone B-cell mucosa-associated lymphoid tissue (MALT) lymphoma is very rare, so it is difficult to diagnose preoperatively. And there is no established treatment for hepatic MALT lymphoma. We report herein a case of primary hepatic MALT lymphoma treated by laparoscopic partial hepatectomy, and discuss the usefulness of laparoscopic hepatectomy for a rare liver tumor. CASE PRESENTATION This patient was a woman in her 60s, who was diagnosed preoperatively as having synchronous liver metastasis from sigmoid colon cancer; therefore, laparoscopic partial hepatectomy was performed. She had a good course after the operation and was discharged on postoperative day 12. However, she was diagnosed pathologically as having primary hepatic MALT lymphoma. A bone marrow biopsy was also performed, and then she was finally diagnosed as having limited-stage primary hepatic MALT lymphoma. She received no postoperative treatment and showed no recurrence for 4 years postoperatively. CONCLUSIONS We experienced the good result of the patient with limited-stage primary MALT lymphoma treated by laparoscopic partial hepatectomy. Liver tumors are sometimes misdiagnosed by imaging examinations alone. Laparoscopic hepatectomy has been widespread recently as a minimally invasive procedure, and it may be useful for both diagnosis and treatment.

Abstract
PURPOSE This study aimed to evaluate the technical and clinical success rates of transcatheter arterial embolization (TAE) for subcapsular hematoma of the liver. METHODS Between January 2010 and March 2022, 34 patients underwent TAE for subcapsular hematomas of the liver. The causes of subcapsular hematoma were liver tumor rupture (n = 12), trauma (n = 12), iatrogenic complications (n = 9), and spontaneous bleeding (n = 1). The technical and clinical success rates of TAE, blood test results after TAE and additional treatments were evaluated. The patients were divided into either with or without retrograde segmental or lobar portal venous flow on angiography. Technical and clinical success rates and blood test results after TAE were compared between the two groups. RESULTS Technical and clinical success rates were 94.1% and 73.5%, respectively. Six patients died within one month of TAE. A repeat TAE was performed in three patients. Surgical removal and hemostasis for subcapsular hematoma were done in four patients. One patient had liver failure. The retrograde portal venous flow was observed in 18 patients. The difference in technical and clinical success rates and blood test results after TAE between the two groups was statistically insignificant. CONCLUSION TAE is an effective and safe treatment for subcapsular hematomas of the liver. The success rates of TAE and liver damage due to TAE did not differ between patients with and without retrograde portal venous flow.

Abstract
Astrophysical reactions involving radioactive isotopes (RI) often play an important role in high-temperature stellar environments. The experimental studies on the reaction rates for those are still limited mainly due to the technical difficulties in producing high-quality RI beams. A direct measurement of those reactions would be still challenging in many cases, however, we can make a reliable evaluation of the reaction rates by an indirect method or by studying the resonance prorerties. Here we ntroduce recent examples of experimental studies on such RI-involving astrophysical reactions, performed at Center for Nuclear Study, the University of Tokyo, using the low-energy RI beam separator CRIB. One is for the neutron-induced destruction reactions of 7Be in the Big-Bang nucleosynthesis, and the other is the study on the 22Mg(α, p) reaction relevant in X-ray bursts, which was performed with the resonant scattering method from the inverse reaction channel.

Abstract
Background Surgical treatment for PV (portal vein) stenosis/occlusion can pose a fatal risk of massive bleeding from severe adhesions and collateral vessel formation. PV stents placement is a minimally invasive and effective procedure for PV stenosis/occlusion, but PV stents sometimes occlude. The relationship between post-stent PV hemodynamics and stent occlusion has not been thoroughly investigated. Certain precautions during PV stent placement may reduce the risk of stent occlusion. This study aimed to evaluate long-term outcomes of PV stent patency and investigate factors including PV hemodynamics associated with stent occlusion. Materials and methods Thirty-four consecutive patients with PV stenosis/occlusion who underwent PV stent placement in four institutions between December 2006 and February 2021 were retrospectively examined. The primary study endpoints were technical success, clinical success, and cumulative stent patency rate. The secondary endpoints were risk factors of stent occlusion. A univariable Cox proportional hazards model with sixteen variables was used to determine predictors of stent occlusion. Factors with p-value ≤ 0.1 in univariable analysis were included in the multivariable analysis. Alpha was set at 0.05. Results Technical and clinical success rates were 88.2% and 79.4%, respectively. Six patients (17.7%) experienced stent occlusion. The cumulative stent patency rate at six months, one year, and three years was 79.1%, 79.1%, and 65.9%, respectively. In the univariate analysis, the variables with p-value ≤ 0.1 were lesion length > 4 cm, hepatofugal collateral vein visualization after stent placement, and residual stenosis > 30% after stent placement. In the multivariate analysis, residual stenosis > 30% after stent placement was significantly associated with stent occlusion (hazard ratio, 10.80; 95% confidence interval, 1.08–108.44; p = 0.04). Conclusion PV stent placement was technically feasible and effective in improving portal hypertension. However, stent occlusion was not uncommon. Residual stenosis > 30% after stent placement was significantly associated with stent occlusion. We should pay attention to correctly assess the range of stenosis and release the stenosis as much as possible.

Abstract
Background Transcatheter arterial embolization (TAE) is widely accepted as a treatment for bleeding from the pancreaticodoudenal artery (PDA) in patients with celiac artery stenosis. However, the technical aspect of TAE has not received much attention. Purpose To report the technical details and success rate of TAE for bleeding from the PDA in patients with CA stenosis. Material and Methods Between 2015 and 2021, nine TAE procedures were performed in eight patients (five women, three men; one woman underwent TAE twice). The cause of CA stenosis was compression by the median arcuate ligament in eight cases and CA dissection in one case. The cause of bleeding was flow-related aneurysm rupture in six cases. Pre-TAE CT showed a pseudoaneurysm in all cases. The technical details of TAE were recorded, and the success rate was evaluated. Results The technical and clinical success rates were 100%. In six cases, both the CA and superior mesenteric artery (SMA) were cannulated using two parent catheters: a microcatheter advancing to the pseudoaneurysm from the CA (the CA approach) to achieve embolization and another catheter for angiography advancing from the SMA to map the vascular anatomy. In five cases, the CA approach was successfully performed after failed attempts of advancing a microcatheter from the SMA. Conclusion TAE is an effective treatment for bleeding from the PDA in patients with CA stenosis. Using two parent catheters, one for CA cannulation and microcatheter advancement and another for SMA cannulation and vascular mapping, may be a useful technique.

Abstract
Abstract
Background
Understandings of subtypes of atypical atrioventricular nodal reentrant tachycardia (AVNRT) using variants of slow pathway (SP) are still growing. Inferolateral (inf-lat-) left atrial (LA) SP is a rare variant extending into an inf-lat-LA along the mitral annulus (MA).
Purpose
To characterize an unknown subtype of atypical fast-slow (F/S-) AVNRT using an inf-lat-LA-SP as a retrograde limb (inf-lat-LA-F/S-AVNRT).
Methods
This Japanese multicenter retrospective study enrolled 4 patients of inf-lat-LA-F/S-AVNRT that was characterized by the earliest site of atrial activation during tachycardia (EAA) between 3 and 6 o'clock along the MA. The diagnosis was made by an exclusion of AV reentrant tachycardia (AVRT) and atrial tachycardia (AT) according to the standard criteria and was confirmed by successful elimination of tachycardia and the inf-lat-LA-SP.
Results
Surface ECG during tachycardia revealed long RP appearance except one who had short RP due to a short conduction time across the inf-lat-LA-SP. During tachycardia, far-field LA activation preceding near-field activation of coronary sinus (CS) musculature was visible in the CS recording in 2. Retrograde conduction via the inf-lat-LA-SP with a decremental delay was consistently reproducible with ventricular stimulation in 2, 1 of whom had double atrial response, while it was always masked by the presence of a retrograde conduction via the fast pathway in 1 and a retrograde block at the lower common pathway in 1. An injection of a small dose of ATP transiently interrupted a retrograde conduction over the inf-lat-LA-SP, suggesting its ATP-sensitivity. Exclusion of AVRT was made by no resetting of tachycardia with left ventricular extrastimulus in 2 and VA dissociation during overdrive pacing of tachycardia in remaining 2. Exclusion of AT was made by V-A-V response after ventricular entrainment in 1 and termination without atrial capture by ventricular pacing in 2. Ablation of the right-sided SP was unsuccessful to eliminate the tachycardia, but ablation at or near the EAA by transseptal approach was successful to cure the tachycardia, associated with an elimination of a retrograde conduction over the inf-lat-LA-SP following a development of an accelerated junction rhythm in all. Low-frequency potentials preceding local atrial activation, consistent with a retrograde activation via the inf-lat-LA-SP were detected along the MA medial to the EAA in 1.
Conclusions
Differential diagnosis of tachycardia with the EAA in the inf-lat-LA and especially long RP appearance should include inf-lat-LA-F/S-AVNRT. Presumed arrhythmogenic substrate of the inf-lat-LA-SP seemed to be consistent with the remnant of embryogenic AV ring tissue in the electropharmacological and locational characteristics. Successful elimination of this AVNRT can be obtained by ablation of the inf-lat-LA-SP, but not of the right-sided SP.

Abstract
In hepatectomy, the Pringle maneuver is commonly used, but its association with iatrogenic injury is not yet well understood. This report presents a case of dissecting aneurysm of the proper hepatic artery (PHA) possibly associated with the Pringle maneuver during laparoscopic hepatectomy, that was successfully treated by transcatheter arterial embolization (TAE). The patient was a woman in her 70s, and repeat hepatectomy for liver metastasis of rectal neuroendocrine neoplasm was planned. She underwent hand-assisted laparoscopic hepatectomy with the Pringle maneuver. On postoperative day (POD) 7, enhanced computed tomography showed a dissecting aneurysm of the PHA. TAE of the PHA to prevent hemorrhage was performed on POD 9 with no complications. Even after TAE, intrahepatic arterial flow was provided by the peribiliary arteries. This case suggests the possibility that the Pringle maneuver can cause a dissecting aneurysm of the hepatic artery.

Abstract
AIM Simple hepatic cysts are typically benign; however, when they are large and symptomatic, therapeutic intervention is required. We previously reported our initial experience with ultrasound (US)-guided polidocanol foam sclerotherapy in three patients with symptomatic giant hepatic cysts. In the present study, we examined the efficacy and safety of polidocanol foam sclerotherapy in a larger number of patients with long-term follow-up. METHODS Between May 2016 and April 2021, 15 patients with symptomatic giant hepatic cysts were referred to our hospital. All patients were prospectively included in the study and underwent US-guided polidocanol foam sclerotherapy. RESULTS The mean maximum diameter and estimated cyst volume were 128.4 mm (77-223 mm) and 922.3 ml (123.2-2797 ml), respectively. Polidocanol foam was successfully administered through an 8.5-Fr pigtail catheter in all patients. The percentages of cyst diameter/volume after 1-3 months, 3-6 months, 6 months-1 year, 1-2 years, and 2-4 years of sclerotherapy were 66.8%/36.5%, 48.1%/14.8%, 34.1%/6.9%, 28.2%/3.7%, and 26.2%/3.1%, respectively. During the follow-up period, there were no cases of symptom recurrence or need for additional treatment due to cyst re-growth. Six patients (40%) had fever, one had nausea, and one had right-sided chest pain, but none of these adverse events required prolonged hospitalization or readmission. CONCLUSIONS US-guided polidocanol foam sclerotherapy may be an effective and safe method for the treatment of symptomatic giant hepatic cysts.

Abstract
Patients experiencing severe side effects when taking high-risk drugs may have a significantly reduced health-related quality of life (QOL); therefore, it is important to identify changes in the health-related QOL in these patients. This study aimed to determine the health-related QOL in community pharmacy outpatients taking high-risk drugs. This prospective observational study was conducted in 29 community pharmacies with 71 pharmacists in 12 regions and cities in Japan from October to December 2020 and 760 patients were enrolled. Using descriptive questionnaires of EuroQOL-5-dimensions-5-levels (EQ-5D-5L), community pharmacists obtained health-related QOL data from outpatients taking high-risk drugs. The mean health-related QOL of all outpatients was 0.869. The health-related QOL decreased with increasing age. The outpatient health-related QOL was 0.700, 0.763, 0.785, and 0.817 when taking antiepileptic, antidepressant, digitalis, and antiarrhythmic drugs, respectively, which was lower than the average health-related QOL of all outpatients. Mobility and pain/ discomfort accounted for a large proportion of the decline in the health-related QOL with increasing age. There were no significant differences in personal care with increasing age; however, the number of outpatients with mobility, normal activity, and pain challenges decreased with age. In contrast, outpatients aged <65 years with anxiety/depression showed a lower than overall average health-related QOL. To the best of our knowledge, this is the first study in Japan to report an investigation by community pharmacists regarding health-related QOL assessment in outpatients taking high-risk drugs.

Abstract
BackgroundRapid glucocorticoid (GC) tapering is recommended for lupus nephritis (LN) by 2019 EULAR/ERA-EDTA recommendations [1]. However, slower conventional GC tapering regimen is still common in the real world setting, and it is controversial whether a rapid GC tapering regimen is as effective as the conventional regimen.ObjectivesWe aimed to compare the renal outcomes between rapid and slower GC tapering regimens in patients with LN.MethodsWe retrospectively surveyed the medical records of 27 patients with proliferative LN (class Ⅲ or Ⅳ) at Kobe City Medical Center General Hospital. These patients were divided into two groups (rapid GC tapering group and conventional GC tapering group) according to GC dosage at month 6. Logistic regression analyses were performed to examine the association of GC tapering regimens with achievement of primary efficacy renal response (PERR) and complete renal response (CRR) which were defined by Furie et al. [2] at month 24.ResultsTwenty-seven patients (19 women and 8 men) with class Ⅲ or Ⅳ LN were included. The mean age was 43 years. The mean eGFR and urine protein-to-creatinine ratio at baseline were 66.7 mL/min/1.73m2 and 3.125 g/gCr, respectively. Concomitant class Ⅴ LN was present in 26.0%. The rapid GC tapering group (PSL≦10 mg/day at month 6) and the conventional GC tapering group (PSL>10 mg/day at month 6) were 11 and 16 patients, respectively. Baseline characteristics were balanced between the two groups except for use of cyclophosphamide or mycophenolate mofetil. Mean urine protein-to-creatinine ratio at month 24 were 0.46 g/gCr in the rapid GC tapering regimen group and 1.08 g/gCr in the conventional GC tapering regimen group (p=0.790). Achievements of PERR and CRR at month 24 were 54.0% and 43.8% in the rapid GC tapering group and 54.5% and 25.0% in the conventional GC tapering group, respectively. After adjustment of cyclophosphamide or mycophenolate mofetil usage and urine protein-to-creatinine ratio at baseline, adjusted odds ratio was 1.52 (95% confidence interval [0.126 to 18.29], p=0.743) and 2.99 (95% confidence interval [0.34 to 28.52], p=0.341), respectively.ConclusionOur results suggest rapid GC tapering regimen is as effective as conventional slower tapering regimen for patients with proliferative LN.References[1]Fanouriakis A, Kostopoulou M, Cheema K, et al. 2019 Update of the Joint European League Against Rheumatism and European Renal Association-European Dialysis and Transplant Association (EULAR/ERA-EDTA) recommendations for the management of lupus nephritis.

Abstract
The prognosis of patients with osteosarcoma recurring at extrapulmonary/extraosseous sites, especially those with unresectable tumors, is generally dismal due to high resistance to chemotherapy. The present study describes a pediatric patient with osteosarcoma recurring to the liver and stomach. Complete remission was achieved by long-term systemic chemotherapy with temozolomide+etoposide, local irradiation of the stomach, and radical surgical removal of multiple liver metastases following percutaneous transhepatic portal embolization. Second-line multimodal therapy, consisting of salvage chemotherapy and curative local treatment of metastases, may enhance disease-free survival of patients with osteosarcoma experiencing relapse to uncommon sites.

Abstract
Kasai portoenterostomy (KP) is a standard treatment for patients with biliary atresia (BA). After KP, patients with BA occasionally develop biliary complications, such as recurrent cholangitis, biliary stricture, and cystic dilatation of the intrahepatic bile duct. Percutaneous transhepatic biliary drainage is one of the treatment options for these biliary complications. However, limited information is available on percutaneous transhepatic biliary drainage performed after KP in adult BA patients with native livers. Herein, we describe 8 cases of percutaneous transhepatic biliary interventions performed after KP in 7 adult BA patients with native livers. Cholangiography showed multiple cystic dilatation of the intrahepatic bile ducts. Advancing a guidewire and catheter was difficult due to the multiple dilatations and strictures of the bile duct. Successful biliary drainage tube placement and clinical improvement was achieved in 5 and 3 cases, respectively. Because of its technical difficulty and limited clinical effectiveness, it is not recommended that it be performed easily.

Abstract
An 11-year-old boy with a history of hepatoblastoma treated with chemotherapy, radiation therapy, and liver transplantation presented with bleeding from Roux-en-Y limb varices. The transhepatic approach for portal intervention posed a risk of liver graft injury. An omental vein that was dilated as a collateral vein due to portal hypertension was found and compressible under ultrasound. The omental vein was percutaneously punctured, and the varices were embolized through a jejunal vein. No complication occurred. Direct percutaneous access to the portal venous system is a useful technique for portal embolization.

Abstract
Type I X-ray bursts (XRBs) are the most frequently observed thermonuclear explosions in nature. The 22Mg(α,p)25Al reaction plays a critical role in XRB models. However, experimental information is insufficient to deduce a precise 22Mg(α,p)25Al reaction rate for the respective XRB temperature range. A new measurement of 25Al+p resonant scattring was performed up to the astrophysically interested energy region of 22Mg(α,p)25Al. Several resonances were observed in the excitation functions, and their level properties have been determined based on an R-matrix analysis. In particular, proton widths and spin-parities of four natural-parity resonances above the α threshold of 26Si, which can contribute the reaction rate of 22Mg(α,p)25Al, were first experimentally determined.

Abstract
Experimental studies on astrophysical reactions involving radioactive isotopes (RI) often accompany technical challenges. Studies on such nuclear reactions have been conducted at the low-energy RI beam separator CRIB, operated by Center for Nuclear Study, the University of Tokyo. We discuss two cases of astrophysical reaction studies at CRIB; one is for the 7Be+n reactions which may affect the primordial 7Li abundance in the Big-Bang nucleosynthesis, and the other is for the 22Mg(α, p) reaction relevantin X-raybursts.

Abstract
PURPOSE Reports on the future liver remnant (FLR) hypertrophy rate in patients undergoing portal vein embolization (PVE) before left trisectionectomy are sparse. This study aimed to assess the FLR hypertrophy rate in patients undergoing PVE before left trisectionectomy. METHODS Between January 2010 and June 2021, 30 patients (22 men and eight women; mean age, 65.7 years) underwent PVE, mainly using gelatin sponge, before left trisectionectomy. The preoperative diagnosis was cholangiocarcinoma in 28 patients and colorectal liver metastases in two patients. The FLR hypertrophy rate, increase in the FLR volume (FLRV) ratio (the ratio of the FLRV to the total liver volume), and complications were evaluated. The patients were further divided into two groups: one group of patients with left portal vein stenosis or occlusion before PVE (n = 12) and another without left portal vein stenosis or occlusion before PVE (n = 18). The FLR hypertrophy rate and increase in the FLRV ratio were compared between the two groups. RESULTS The FLR hypertrophy rate and increase in the FLRV ratio were 31.3% and 6.9%, respectively. One major complication, cholangitis, developed; however, its association with PVE was unclear. The difference in the FLR hypertrophy rate and the increase in the FLRV ratio between the two groups of patients was statistically insignificant. CONCLUSION PVE before left trisectionectomy is effective in achieving FLR hypertrophy. PVE before left trisectionectomy was equally effective in patients with left portal vein stenosis or occlusion as compared to those without. The complication rates were acceptable.

Abstract
We describe a case of Trousseau's syndrome in a patient with lung carcinoma. A 69-year-old man presented with pleural effusion. Further evaluation revealed EGFR mutation-positive non-small cell carcinoma in the upper lobe with extensive lymph node, bone, and brain metastases. Administration of osimertinib, an EGFR tyrosine kinase inhibitor, resulted in partial tumor response, but caused osimertinib-induced pneumonitis 10 weeks later. Prednisolone restrained lung injury progression and was gradually tapered. However, he presented with impaired consciousness and right hemiplegia. Magnetic resonance imaging revealed a left middle cerebral artery M1 segment occlusion. D-dimer level was elevated to 19.5 μg/mL. In the absence of atherosclerotic or cardiogenic thrombi, these findings led to the diagnosis of Trousseau syndrome. Endovascular therapy, but not tissue plasminogen activator, improved his condition with no recurrences. These treatment strategies are crucial to restore function in patients with potentially disabling cerebral infarction due to Trousseau syndrome. Systemic anticoagulation for Trousseau syndrome generally has a poor prognosis. There is no established treatment for cancer-associated cerebral infarction. We performed endovascular therapy for cerebral infraction due to Trousseau syndrome. Endovascular therapy was effective for recanalization of the occluded artery. An NIHSS score of 0 was achieved with no recurrence.

Abstract
We report the first (in)elastic scattering measurement of ^{25}Al+p with the capability to select and measure in a broad energy range the proton resonances in ^{26}Si contributing to the ^{22}Mg(α,p) reaction at type I x-ray burst energies. We measured spin-parities of four resonances above the α threshold of ^{26}Si that are found to strongly impact the ^{22}Mg(α,p) rate. The new rate advances a state-of-the-art model to remarkably reproduce light curves of the GS 1826-24 clocked burster with mean deviation <9% and permits us to discover a strong correlation between the He abundance in the accreting envelope of the photospheric radius expansion burster and the dominance of ^{22}Mg(α,p) branch.

Abstract
In pediatric arteriography, vascular complications are more common than in adults; thus, the use of the smallest catheter to accomplish the objective of the procedure is recommended. We describe two pediatric cases in which abdominal arterial embolization and arteriography were performed with steerable microcatheters without conventional diagnostic catheters. Additionally, we used an introducer with an outer diameter of 4-F in a Mini Access Kit (Merit Medical, South Jordan, UT) as a vascular sheath to reduce sheath size. We believe that this technique may be feasible and safe for abdominal arterial interventions in children.

Abstract
Objective: The efficacy of docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy in treating esophageal cancer has been reported. However, febrile neutropenia (FN) is a potentially serious adverse event of DCF therapy with an incidence of 10 to 40%. Pegfilgrastim, a granulocyte colony-stimulating factor (G-CSF), has been shown to have a primary prophylactic role in FN. However, it has been suggested that excessive use of expensive G-CSF should be avoided. Therefore, we performed a cost-utility analysis of primary prophylaxis with pegfilgrastim. Design: Cost-effectiveness analysis using decision tree modelling. Methods: We used a decision tree analysis model based on the report of primary prophylaxis with pegfilgrastim. Based on a previous study, the FN incidence rate was set at 40.0% (95% confidence interval (CI): 11.9-68.1) for the pegfilgrastim group and 43.5% (95%CI: 21.6-65.4) for the no pegfilgrastim group. The FN treatment cost was US$726.63, and the duration of FN was 3.65±1.20 days. The utility value of patients who received DCF therapy was 0.643, and the change in utility value at FN onset was -0.15. Expected cost, quality-adjusted life year (QALY), and incremental cost-effectiveness ratio (ICER) were calculated, and cost-utility analysis was performed. Results: The ICER of pegfilgrastim was 184,976.75 USD/QALY. As a result of sensitivity analysis, the utility of FN had the greatest impact on the cost-effectiveness analysis, followed by the drug cost of pegfilgrastim. Conclusion: Primary prophylaxis of FN with pegfilgrastim might not be cost-effectiveness. In determining whether to administer pegfilgrastim it is necessary to consider patient factors, not just the incidence of FN.

Abstract
A 79-year-old woman with a history of advanced gastric cancer and portal vein tumor thrombus, treated with surgery and chemoradiotherapy, presented with hematemesis due to esophageal variceal bleeding around the esophagojejunal anastomosis. Endoscopic treatment was unsuccessful. Due to portal vein occlusion, percutaneous transhepatic access was difficult. Thus, the middle colic vein, which was dilated due to portal vein occlusion, was percutaneously punctured, and antegrade embolization of a jejunal vein feeding the varices was performed using a microcatheter through a 4-F dilator placed as a sheath. After embolization, the sheath was removed, and ultrasound-guided compression of the puncture site was performed. No bleeding complication occurred. Therefore, direct percutaneous access to a mesenteric vein is a viable alternative to transhepatic access.

Abstract
Polymer-infiltrated ceramic network (PICN) composites are mechanically compatible with human enamel, and are therefore promising dental restorative materials. Fabrication technology for PICN composites used in tooth restorative material has been established through computer-aided design/computer-aided manufacturing (CAD/CAM) milling, however, to date, has not been successfully developed using 3-dimensional (3D) printing. This study aimed to develop a 3D-printable PICN composite as a restorative material. The PICN composite was fabricated using a specific method based on 3D printing. A 3D-printable precursor slurry containing a high concentration of silica nanoparticles was produced and 3D-printed using stereolithography (SLA). The 3D-printed object was sintered to obtain a nano-porous object, and subsequently infiltrated and polymerized with resin monomer. Three different fabrication condition combinations were used to produce the 3D-printed PICN composites, which were characterized based on microstructure, mechanical properties, inorganic content, physicochemical properties, and overall shrinkage. The 3D-printed PICN composites were also compared to 2 commercially available CAD/CAM composite blocks, namely a PICN composite and a dispersed-filler composite. The 3D-printed PICN composites exhibited a nano-sized dual-network structure comprising a silica skeleton with infiltrated resin. The 3D-printed PICN composite exhibited a similar Vickers hardness to enamel, and a similar elastic modulus to dentin. The 3D-printed PICN composite exhibited comparable flexural strength (>100 MPa) to the CAD/CAM block, and acceptable water sorption and solubility for practical use. Further, the 3D-printed model-crown underwent isotropic shrinkage during sintering without fatal deformation. Overall, the potential of this 3D-printable PICN composite as a restorative material with similar mechanical properties to human teeth was successfully demonstrated.

Abstract
We diagnosed rib fractures by palpation, computed tomography, and thoracic necropsy. For 163 symptomatic calves delivered from Holstein-Friesian dams on farms in Japan, 11.0% (18) showed rib fractures by palpation. Four of five calves that were scanned or necropsied presented with pneumonia despite not having tracheal stenosis. Rib fractures decreased sale prices at a livestock market and longevity.
Cranial rib fractures during dystocia and the ensuing callus formations in calves often cause tracheal stenosis. Rib fractures may affect the lung since ribs tend to fracture above the costochondral junction during delivery. Considering that calving assistance rates for dystocia are high, calves with fractured ribs may develop respiratory disease which results in economic loss. The objective of this study was to elucidate the contribution of rib fractures to economic loss through respiratory disease in calves. Of 163 sick calves delivered from Holstein-Friesian dams included in this study, a total of 18 rib fractured calves was found, giving an incidence of rib fracture in sick calves of 11.0%. There were significant differences in incidence by the rib involved, indicating the 2nd to 7th ribs tend to break. Many of the rib fractured calves showed dyspnea and pyrexia. In this study, four of five scanned or necropsied calves had pneumonia lesions despite the fact that these four calves did not have tracheal stenosis. Rib fractured calves sold at below market value with a median difference from average sale price of minus 64,861 yen. Survival analysis indicated an overall association between rib fracture and time to death. In this study, we demonstrated that rib fractures happened most frequently in the 2nd to 7th ribs, and these cases tended to cause pneumonia, which decreased sale prices and longevity. Farmers should work to reduce risks and rates of dystocia so as to lessen economic loss and poor welfare in calves due to rib fractures.

Abstract
The aim of this study was to develop a head-chest phantom that could mimic the physique of a Japanese 0.5-year-old child and to investigate the current status of exposure dose in infant head computed tomography examinations in Japan. The phantom was produced by machine processing, and radiophotoluminescence glass dosemeters were installed in the phantom for dose measurement. Organ doses were measured for seven different head scan protocols routinely used in three hospitals. In this study, the average dose of the brain and lens within the scan region was equivalent to that measured using infant phantoms in previous studies. In contrast, the doses of both salivary glands and thyroid glands adjacent to the scan region were 1.4-1.8 times higher than those in previous studies. Expansion of the scan area accompanied by a transition of the scan mode from non-helical to helical may have resulted in the differences in organ doses.
