Abstract
PURPOSE Survival rates of patients with high-risk neuroblastoma are unacceptable. A time-intensified treatment strategy with delayed local treatment to control systemic diseases has been developed in Japan. We conducted a nationwide, prospective, single-arm clinical trial with delayed local treatment. This study evaluated the safety and efficacy of delayed surgery to increase treatment intensity. PATIENTS AND METHODS Seventy-five patients with high-risk neuroblastoma were enrolled in this study between May 2011 and September 2015. Delayed local treatment consisted of five courses of induction chemotherapy (cisplatin, pirarubicin, vincristine, and cyclophosphamide) and myeloablative high-dose chemotherapy (melphalan, etoposide, and carboplatin), followed by local tumor extirpation with surgery and irradiation. The primary endpoint was progression-free survival (PFS). The secondary endpoints were overall survival (OS), response rate, adverse events, and surgical complications. RESULTS Seventy-five patients were enrolled, and 64 were evaluable (stage 3, n = 8; stage 4, n = 56). The estimated 3-year PFS and OS rates (95% confidence interval [CI]) were 44.4% [31.8%-56.3%] and 80.7% [68.5%-88.5%], resspectively. The response rate of INRC after completion of the treatment protocol was 66% (42/64; 95% CI: 53%-77%; 23 CR [complete response], 10 VGPR [very good partial response], and nine PR [partial response]). None of the patients died during the protocol treatment or within 30 days of completion. Grade 4 adverse effects, excluding hematological adverse effects, occurred in 48% of patients [31/64; 95% CI: 36%-61%]. Major Surgical complications were observed in 25% of patients [13/51; 95% CI: 14%-40%]. CONCLUSION This study indicates that delayed local treatment is feasible and shows promising efficacy, suggesting that this treatment should be considered further in a comparative study of high-risk neuroblastoma.

Abstract
Non-small-cell lung cancer (NSCLC) with comorbid interstitial pneumonia (IP) is a population with limited treatment options and a poor prognosis. Patients with comorbid IP are at high risk of developing fatal drug-induced pneumonitis, and data on the safety and efficacy of molecularly targeted therapies are lacking. KRAS mutations have been frequently detected in patients with NSCLC with comorbid IP. However, the low detection rate of common driver gene mutations, such as epidermal growth factor receptor and anaplastic lymphoma kinase, in patients with comorbid IP frequently results in inadequate screening for driver mutations, and KRAS mutations may be overlooked. Recently, sotorasib and adagrasib were approved as treatment options for advanced NSCLC with KRASG12C mutations. Although patients with comorbid IP were not excluded from clinical trials of these KRASG12C inhibitors, the incidence of drug-induced pneumonitis was low. Therefore, KRASG12C inhibitors may be a safe and effective treatment option for NSCLC with comorbid IP. This review article discusses the promise and prospects of molecular-targeted therapies, especially KRASG12C inhibitors, for NSCLC with comorbid IP, along with our own clinical experience.

Abstract
BACKGROUND It remains controversial whether a cancer history increases the risk of cardiovascular (CV) events among patients with myocardial infarction (MI) who undergo revascularization.Methods and Results: Patients who were confirmed as type 1 acute MI (AMI) by coronary angiography were retrospectively analyzed. Patients who died in hospital or those not undergoing revascularization were excluded. Patients with a cancer history were compared with those without it. A cancer history was examined in the in-hospital cancer registry. The primary outcome was a composite of cardiac death, recurrent type 1 MI, post-discharge coronary revascularization, heart failure hospitalization, and stroke. Among 551 AMI patients, 55 had a cancer history (cancer group) and 496 did not (non-cancer group). Cox proportional hazards model revealed that the risk of composite endpoint was significantly higher in the cancer group than in the non-cancer group (adjusted hazard ratio [HR]: 1.78; 95% confidence interval [CI]: 1.13-2.82). Among the cancer group, patients who were diagnosed as AMI within 6 months after the cancer diagnosis had a higher risk of the composite endpoint than those who were diagnosed as AMI 6 months or later after the cancer diagnosis (adjusted HR: 5.43; 95% CI: 1.55-19.07). CONCLUSIONS A cancer history increased the risk of CV events after discharge among AMI patients after revascularization.

Abstract
Allergies to dogs and cats can cause enormous damage to human health and the economy. Dog and cat allergens are mainly found in dog and cat dander and are present in small particles in the air and in carpets in homes with dogs and cats. Cleaning houses and washing pets are the main methods for reducing allergens in homes; however, it is difficult to eliminate them completely. Therefore, we aimed to investigate whether a TiO2 photocatalyst could degrade dog and cat allergens. Under wet conditions, exposure to the TiO2 photocatalyst for 24 h degraded Can f1, which is a major dog allergen extracted from dog dander, by 98.3%, and Fel d1, which is a major cat allergen extracted from cat dander, by 93.6-94.4%. Furthermore, under dry conditions, the TiO2 photocatalyst degraded Can f1 and Fel d1 by 92.8% and 59.2-68.4%, respectively. The TiO2 photocatalyst abolished the binding of dog and cat allergens to human IgE by 104.6% and 108.6%, respectively. The results indicated that the TiO2 photocatalyst degraded dog and cat allergens, causing a loss in their allergenicity. Our results suggest that TiO2 photocatalysis can be useful for removing indoor pet allergens and improving the partnership between humans and pets.

Abstract
BACKGROUND T-cell acute lymphoblastic leukaemia has distinct biological characteristics and a poorer prognosis than B-cell precursor acute lymphoblastic leukaemia. This trial aimed to reduce the rate of radiation and haematopoietic stem-cell transplantation (HSCT) while improving outcomes by adding nelarabine, intensified L-asparaginase, and protracted intrathecal therapy in the Berlin-Frankfurt-Münster (BFM)-type treatment. METHODS In this nationwide, multicenter, phase 2 trial, we enrolled patients with newly diagnosed T-cell acute lymphoblastic leukaemia (age <25 years at diagnosis) conducted by Japan Children's Cancer Group and Japan Adult Leukemia Study Group. Patients were stratified into standard-risk, high-risk, and very-high-risk groups according to prednisolone response, CNS status, and end-of-consolidation minimal residual disease. We used the Associazione Italiana di Ematologia Oncologia Pediatrica (AIEOP)-BFM-ALL 2000-backbone chemotherapy. Nelarabine (650 mg/m2 per day for 5 days) was given to high-risk and very high-risk patients. All patients received, until the measurement of end-of-consolidation minimal residual disease, an identical therapy schedule, which included the prednisolone pre-phase remission induction therapy with dexamethasone (10 mg/m2 per day, for 3 weeks [for patients <10 years] or for 2 weeks including a 7-day off interval [for patients ≥10 years]) instead of prednisolone, and consolidation therapy added with Escherichia coli-derived L-asparaginase. On the basis of the stratification, patients received different intensities of treatment; L-asparaginase-intensified standard BFM-type therapy for standard risk and nelarabine-added high risk BFM-type therapy for high risk. In the very high-risk group, patients were randomly assigned (1:1) to group A (BFM-based block therapy) and group B (another block therapy, including high-dose dexamethasone) stratified by hospital, age (≥18 years or <18 years), and end-of-induction bone marrow blast percentage of M1 (<5%) or M2 (≥5%, <25%)+M3 (≥25%). Cranial radiotherapy was limited to patients with overt CNS disease at diagnosis (CNS3; >5 white blood cells per μL with blasts) and patients with no evidence of CNS disease received protracted triple intrathecal therapy. Only very high-risk patients were scheduled to receive HSCT. The primary endpoint was 3-year event-free survival for the entire cohort and the proportion of patients with disappearance of minimal residual disease between randomly assigned groups A and B in the very high-risk group. Secondary endpoints were overall survival, remission induction rate, and occurrence of adverse events. 3 years after the completion of patient accrual, a primary efficacy analysis was performed in the full analysis set and the per-protocol set. This study is registered with the Japan Registry of Clinical Trials, jRCTs041180145. FINDINGS Between Dec 1, 2011, and Nov 30, 2017, of 349 eligible patients (median age 9 years [IQR 6-13]), 238 (68%) were male, and 28 (8%) patients had CNS3 status. 168 (48%) patients were stratified as standard risk, 103 (30%) as high risk, 39 (11%) as very high risk, and 39 (11%) as no risk (patients who had off protocol treatment before risk assessment. The composite complete remission (complete remission plus complete remission in suppression) rate after remission induction therapy was 89% (298 of 335 patients). HSCT was performed in 35 (10%) of 333 patients. With a median follow-up of 5·2 years (IQR 3·6-6·7), 3-year event-free survival was 86·4% (95% CI 82·3-89·7%) and 3-year overall survival was 91·3% (87·7-93·8%). The proportion of minimal residual disease disappearance was 0·86 (12 of 14 patients; 95% CI 0·57-0·98) in group A and 0·50 (6 of 12 patients, 0·21-0·79) in group B. Grade 3 peripheral motor neuropathy was seen in 11 (3%) of 349 patients and sensory neuropathy was seen in 6 (2%) patients. The most common grade 3 or worse adverse event was febrile neutropenia (294 [84%] of 349 patients). Treatment-related death occurred in three patients due to sepsis, gastric perforation, or intracranial haemorrhage during remission induction. INTERPRETATION The ALL-T11 protocol produced encouraging outcomes with acceptable toxicities despite limited cranial radiotherapy and HSCT use.

Abstract
Hydrothermal carbonization (HTC) reacts with biomass in water at a high temperature and pressure to produce hydrochar with a higher heating value (HHV) and lower ash content than dry torrefaction. The high potassium content in biomass can promote thermochemical conversion; however, it lowers the melting temperature of the ash, causing slugging and fouling. Therefore, this study, investigated the effect of potassium on the HTC of sorghum bagasse by comparing the removal of potassium by washing with the addition of K2CO3. Consequently, the ash content was the highest in the potassium-added hydrochar and was 3.81% at a reaction time of 2 h. Elemental analysis showed that the lower the potassium content, the higher the carbon content, and the hydrochar with potassium removed by water washing at a reaction time of 3 h had the highest carbon content at 68.3%. Fourier transform infrared spectrometer showed dehydration and decarboxylation reactions due to HTC, but no significant differences were observed between the potassium concentrations. The mass yield decreased with increasing potassium content, and was 27.2% for the potassium-added hydrochar after 3 h. This trend was more pronounced with increasing reaction temperature. On the other hand, HHV was not affected by the potassium content. Therefore, the energy yield was similar to the weight yield. Thermal gravimetry and derivative thermal gravimetry (TG-DTG) analysis showed that higher potassium tended to accelerate the decomposition of lignin and decrease the oxidation temperature.

Abstract
BACKGROUND BCOR CCNB3 sarcoma is a rare mesenchymal tumor that was formerly included in the undifferentiated/unclassified sarcoma group and was recently reclassified as one of undifferentiated small round cell sarcomas with a genetically distinct subtype in the WHO 2020 classification. Because of its rarity, still not much is known, especially about its clinical features. CASE REPORT A 15-year-old boy presented with almost 1-year intermittent thigh pain. On the first visit, a pathologic fracture of the femur and a big mass expanding through the femoral cortex with lobular shape and homogenous appearance were recognized on radiography and magnetic resonance imaging. Plain radiography, which was taken 6 months before at a local clinic, showed an expansion and thickening of the right proximal femoral shaft. Biopsy specimen of the lesion revealed a proliferation of round to spindle tumor cells with diffuse and strong immunohistochemical nuclear positivity for BCOR and CCNB3. Under the diagnosis of BCOR::CCNB3 sarcoma of the femur, a chemotherapy based on a protocol of Ewing sarcoma, followed by a wide resection and total femoral replacement surgery, were conducted. The effect of chemotherapy was favorable, showing no microscopic residual tumor. Although postoperative chemotherapy was not completed because of a minor infection detected on the surgical site, the patient was doing well, without any recurrence, for 26 months. CONCLUSIONS BCOR CCNB3 sarcoma of the bone is a quite rare tumor with much lower incidence than Ewing sarcoma. Notable clinical characteristics of the current case were a 1-year-long symptomatic period and homogenous appearance on MRI.

Abstract
BACKGROUND Intra-articular administration of adipose tissue-derived stem cells (ADSC) is an alternative treatment option for knee osteoarthritis (OA) after conventional treatment fails; however, the clinical results related to the severity of OA grade and changes of cartilage volumes after the administration of ADSC is unknown. This study aimed to determine 1) clinical outcomes after the ADSC administration in knee OA with consideration of radiographic OA grades and 2) changes in cartilage volumes after ADSC administration. METHODS This observational study included 86 knees from 51 patients who underwent intra-articular administration of cultured ADSC; 47 patients (80 knees) completed follow-up for 6 months (follow-up rate: 93%). The Knee injury and Osteoarthritis Outcome Scores (KOOS) were reported at baseline and 1, 3, and 6 months after the administration. The efficacy rate in the Outcome Measures in Arthritis Clinical Trials-Osteoarthritis Research Society International (OMERACT-OARSI) was evaluated using the KOOS. Cartilage volume of the knee joint was measured using quantitative 3-dimensional magnetic resonance imaging (3D-MRI) software at baseline and 6 months in 52 knees in 31 patients (follow-up rate: 61%). RESULTS All items on the KOOS except "sports/recreation" improved significantly at 6 months with more significance in knees with a Kellgren-Lawrence (KL) grade 2 or 3 compared with KL grade 4 knees. The OMERACT-OARSI responder at 6 months was significantly greater in knees with KL grade 2 or 3 (64%) than in knees with KL grade 4 (42%, p = 0.045). Cartilage volume changes varied among patients and were not related to the changes in KOOS after ADSC administration. CONCLUSIONS Intra-articular administration of ADSC in knee OA improved KOOS at 6 months. The effects were more significant in knees with KL grade 2 or 3 than with KL grade 4. Changes in KOOS were not related to change in cartilage volumes after ADSC administration.

Abstract
BACKGROUND Follow-up care for adolescent childhood cancer survivors (ACCS) after they return to school requires an understanding of their psychosocial issues. Therefore, this study developed the adolescent childhood cancer survivors' psychosocial issues scale (ACCSPIS) and evaluated its reliability and validity. METHODS In the development phase, pediatric oncology clinical professionals created the 24 item questionnaire of ACCS's psychosocial issues. In the feasibility phase, a survey was administered to 165 ACCS aged 12-18 years after discharge from hospital in Japan, and 57 completed questionnaires were analyzed. The survey items were psychosocial issues, attributes, K6 scale, and impact of event scale-revised (IES-R) scale. Factor analysis was conducted for psychosocial issues. Regarding reliability, Cronbach's α coefficients and item-total correlation coefficients were calculated. Regarding validity, Spearman's rank correlation coefficients between ACCSPIS and K6 and IES-R were calculated, and confirmatory factor analysis was conducted. RESULTS Four factors comprising 15 items were extracted: "appearance changes due to treatment effects," "anxiety about marriage and the future," "change in appearance due to treatment", and "psychological distress due to interpersonal relationships and information about the disease." The model fit was good, with a total ACCSPIS α coefficient of 0.901 and α coefficients for the subscales ranging from 0.651 to 0.914. The K6 and IES-R were significantly associated with the total ACCSPIS, and item-total correlations were satisfactory. CONCLUSIONS The reliability and validity of ACCSPIS were generally confirmed. This scale could be useful to measure psychosocial issues in ACCS aged 12-18 years after their return to school.

Abstract
Small-cell lung cancer (SCLC) is a highly malignant tumor, and no standard third-line therapy has been established. The present study retrospectively analyzed the efficacy and safety of platinum-based regimens in patients with third-line SCLC who received third-line chemotherapy. The association of regimen type with overall survival (OS) or time to treatment failure (TTF) was evaluated using the Cox hazard proportional method, including well-known covariates affecting the prognosis of SCLC. TTF and OS analyses were conducted using the Kaplan-Meier method. The data cutoff date was June 30, 2020. As a result, from January 2015 to August 2019, 111 patients were diagnosed with SCLC, and 37 received third-line chemotherapy. Subsequently, 15 patients received a platinum-doublet regimen, and 22 patients received a single-agent regimen. Only the type of regimen was significantly associated with TTF in univariate analysis (odds ratio, 0.44; 95% confidence interval, 0.20-0.95; P=0.03). There were no significant factors associated with OS. The median TTF of patients receiving a platinum-doublet regimen and those receiving a single-agent regimen were 3.9 and 2.3 months, respectively (P=0.03). The overall response rates of the platinum-doublet and single-agent regimens were 20.0 and 4.5%, respectively. Similarly, the disease control rates were 73.3 and 36.4% for platinum-doublet and single-agent regimens, respectively. There was a tendency for adverse events (AEs) with any grade to occur more often in platinum-based regimens compared with in single-agent regimens. Severe AEs of grade 3 or higher were observed more often in the platinum-based regimen, especially in myelosuppression. In conclusion, the present study demonstrated the feasibility and safety of platinum-doublet regimens in patients with SCLC in a third-line setting (Registration no. 2020-048. Date of registration, June 5, 2020).

Abstract
INTRODUCTION MEFV is the gene responsible for familial Mediterranean fever (FMF). It encodes pyrin, which controls inflammation; Besides, previous studies have reported that some germline MEFV variants were associated with tumour susceptibility. MATERIALS AND METHODS The loci of 12 germline MEFV variants were genotyped in 153 Japanese children with cancer, and the frequencies of these variants among the patient groups were compared with those in the general Japanese population. Additionally, the relationship between these variants and clinical data, including relapse and death, was investigated. RESULTS Minor allele frequencies did not differ between patients and the general population, or between sex, age at diagnosis, and diagnosis among patients. P369S/R408Q associated with significantly lower relapse-free survival in all patient analyses and in patients with solid tumours. Additionally, although the results were not significant, E148Q/L110P was likely to associate with worse relapse-free survival in patients with solid tumours. DISCUSSION/CONCLUSION Despite several limitations, this study provided the novel insight that the germline MEFV variants are associated with the clinical outcome of paediatric cancer.

Abstract
This study investigated the combustion kinetics and spontaneous ignition of sweet sorghum using thermogravimetric analysis and the Frank-Kamenetskii theory. The aim was to determine the proper operating conditions for a direct combustion reactor and predict the safe ambient temperature limits for given silo designs. Oxidative heating rates of 2, 5, and 10 °C/min were set up. Graphical observation shows that combustion was composed of two different stages representing the overlapping processes of pyrolysis and char oxidation, at 131-336 °C and 336-475 °C, respectively. Samples were found to ignite at 215 °C and were extinguished at 433 °C. Different heating rates shifted combustion characteristics to higher temperatures and increased reactivity for ignition and combustion indices up to 12 and 10 times higher. The Friedman method determined the apparent activation energies representing the combustion reaction by 132.91 kJ/mol. Regarding spontaneous ignition, the temperature safe limits were predicted to be 83-84 °C and 84-87 °C for cylindrical and box silos with diameter and height of 15 and 10 m, respectively. Calculations of silos were designed within the limits of certain dimension ratios.

Abstract
We describe a case of diabetic ketoacidosis (DKA) shortly after the SARS‐CoV‐2 (COVID‐19) vaccination in a 65‐year‐old woman with non–small‐cell lung cancer under a combination treatment of programmed cell death protein 1 (PD‐1) and cytotoxic T‐lymphocyte‐associated protein 4 (CTLA‐4) inhibitors. She had no history of diabetic mellitus. A few days after the second shot of COVID‐19 vaccination, she developed DKA. We speculate that the immune‐related adverse event and immunogenicity of vaccination synergistically induced DKA.

Abstract
Objective Although blood thrombogenicity seems to be one of the determinant factors for the development of acute myocardial infarction (MI), it has not been dealt with in-depth. This study aimed to investigate blood thrombogenicity and its change in acute MI patients. Methods and Results We designed a prospective, observational study that included 51 acute MI patients and 83 stable coronary artery disease (CAD) patients who underwent cardiac catheterization, comparing thrombogenicity of the whole blood between: (1) acute MI patients and stable CAD patients; and (2) acute and chronic phase in MI patients. Blood thrombogenicity was evaluated by the Total Thrombus-Formation Analysis System (T-TAS) using the area under the flow pressure curve (AUC 30 ) for the AR-chip. Acute MI patients had significantly higher AUC 30 than stable CAD patients (median [interquartile range], 1,771 [1,585-1,884] vs. 1,677 [1,527-1,756], p = 0.010). Multivariate regression analysis identified acute MI with initial TIMI flow grade 0/1 as an independent determinant of high AUC 30 ( β = 0.211, p = 0.013). In acute MI patients, AUC 30 decreased significantly from acute to chronic phase (1,859 [1,550-2,008] to 1,521 [1,328-1,745], p = 0.001). Conclusion Blood thrombogenicity was significantly higher in acute MI patients than in stable CAD patients. Acute MI with initial TIMI flow grade 0/1 was significantly associated with high blood thrombogenicity by multivariate analysis. In acute MI patients, blood thrombogenicity was temporarily higher in acute phase than in chronic phase.

Abstract
A 60-year-old man with out-of-hospital cardiac arrest was transported to our hospital by an emergency medical service. Ventricular fibrillation was finally terminated after the initiation of circulation support by percutaneous cardiopulmonary support device. Although acute myocardial infarction was suspected, emergency coronary angiography could not identify the culprit lesion of myocardial infarction while there were multiple intermediate stenotic lesions. Since re-elevation of troponin I was recorded on the 4th day after admission, coronary angiography was performed again, and diffuse severe stenosis in the right coronary artery and total occlusion in the left circumflex coronary artery that disappeared by the injection of isosorbide dinitrate was detected. Therefore, we reached the diagnosis of acute myocardial infarction due to coronary vasospasm. It is very rare that emergency coronary angiogram reveals coronary vasospasm at the culprit lesion of myocardial infarction. The guideline recommends calcium channel antagonist and long-acting nitrates for vasospastic angina; however, it would be really difficult to make correct diagnosis of coronary vasospasm among the patients with acute myocardial infarction or out-of-hospital cardiac arrest. Repeated measurements of troponin and coronary angiography identified the cause of acute myocardial infarction as coronary vasospasm in the present case. <Learning objective: Coronary vasospasm may be one of important causes of acute MI and of OHCA, although it is difficult to be diagnosed correctly. We should always take into consideration the possibility of coronary vasospasm as the cause of acute MI or OHCA. Repeated measurements of troponin and coronary angiography were useful for the diagnosis of coronary vasospasm in the present case.>.

Abstract
Abstract
Background
Previous studies suggest Cardiac rehabilitation (CR) improve exercise capacity and decline mortality in heart failure (HF) patients. However, some studies show there are HF patients who do not improve exercise capacity by CR and these patients have a higher risk of adverse events in long-term clinical outcome. We investigated whether absence of exercise capacity improvement after in-hospital short-term CR also has adverse effect in long-term clinical outcome.
Methods
In this retrospective study, 130 HF patients who underwent two weeks in-hospital CR after received standardized HF treatment between July 2014 and August 2020 were included. Improvement in exercise capacity was assessed by change in peak oxygen consumption (delta-Peak VO2) measured at 1st and 14th day of CR by cardiopulmonary test. The median delta-PeakVO2 was 1.3 ml·kg-1·min-1. Patients were classified as responder if they demonstrated delta-PeakVO2 ≥1.3 ml·kg-1·min-1 and as non-responder if they demonstrated delta-PeakVO2 <1.3ml·kg-1·min-1. MeanΩ follow-up was 1236 days. The primary outcome was all-cause death.
Result
63 patients (48.4%) were classified as non-responder. Non-responders were older (75.5±10.6 vs 70.8±11.0, P=0.01) and lower estimated glomerular filtration rate (eGFR) (49.7±19.4 vs 57.9±19.2) and lower albumin (3.5±0.5 vs 3.7±0.3 g/dL, P=0.04) than responders. Transtricuspid pressure gradient (TRPG) measured by transthoracic echocardiography was also higher in non-responders (28.5±10.9 vs 22.7±6.3). Predictor of non-responders were TRPG (OR = 1.1, 95% CI 1.02–1.26) and albumin (OR =0.04, 95% CI: 0.003–0.40). In multivariate analysis including delta-PeakVO2 <1.3 ml·kg-1·min-1 (non-responder), age >75, male gender, PeakVO2 at 1st day of CR, body mass index (BMI), left ventricular ejection fraction measured by transthoracic echocardiography, medication of β-blockers showed that delta-PeakVO2 <1.3 ml·kg-1·min-1 (HR =2.8, 95% CI 1.0–7.5), age>75 (HR11.2, 95% CI 2.1–60.1), BMI (HR =0.8, 95% CI 0.6–0.96) were associated with all-cause death.
Conclusion
The absence of exercise capacity improvement after in-hospital short-term CR was the risk of all-cause death. Especially, the HF patients with higher TRPG and lower albumin have a higher probability of becoming a non-responder.

Abstract
BACKGROUND AND AIM OF THE STUDY Coronary artery fistula (CAF) is a relatively rare cardiac anomaly. We investigated long-term outcomes following surgical repair of CAF in adults. METHODS We retrospectively investigated 13 consecutive patients undergoing surgical repair of CAF in our institution between 2008 and 2019 (67.3 ± 10.4 years old, 38% male). CAF types were coronary artery-pulmonary artery fistula (77%), coronary artery-coronary sinus fistula (15%), and both (8%). CAFs originated from the left coronary artery (38%), right coronary artery (8%), and bilateral coronary arteries (38%). Pulmonary and systemic flow (Qp/Qs) was measured in seven patients (54%), with a mean value of 1.52. Seven patients underwent surgery for CAFs alone, and others simultaneously underwent surgery for comorbid cardiac diseases. RESULTS All procedures were conducted under cardiopulmonary bypass. Surgical procedures were direct epicardial ligation of fistula (92%), direct closure of CAF through pulmonary artery incision (38%), direct closure of CAF through coronary sinus incision (8%), or patch closure of CAF through coronary artery incision (8%). Myocardial perfusion scintigraphy showed asymptomatic myocardial ischemia in the right coronary area after surgery in one patient. There were no deaths perioperatively or during follow-up (mean: 66.6 months). There were no coronary or other CAF-related events. CONCLUSIONS Several anatomical variations in CAF were observed which coexist with cardiac disease. Long-term outcomes following surgical repair were satisfactory, and the concurrent intervention of CAFs during surgery for comorbid cardiac disease is useful to prevent future complications related CAFs in adults.

Abstract
For hematopoietic stem cell transplantation to be successful, complications must be managed. Graft-versus-host disease is particularly important, but various other complications, treatment side effects, and relapse of primary disease may also occur. We report an autopsy case of juvenile myelomonocytic leukemia with a blastic crisis, in which activated and recovered autologous macrophage-related complications after cord blood transplantation caused the patient's death. Pathological analysis of autopsy specimens revealed diffuse infiltration of mature macrophages into the skin but scarce lymphocytes. These macrophages were found in the bone marrow interspersed with a small number of blasts that had previously occupied about 60% of the bone marrow before death. The direct cause of death was an opportunistic airway infection due to bone marrow and immune failures triggered by overactivation and proliferation of macrophages. Genetic analysis showed the activated macrophages were autologous. Together these findings indicate that the patient died from macrophage-mediated complications, but not from a blastic crisis or conventional graft-versus-host disease. When macrophage activation persists after hematopoietic stem cell transplantation, macrophage-mediated complications should be considered as a differential diagnosis. To manage this complication, pathology specimens should be examined to check for the presence of effector cells at an early stage.

Abstract
OBJECTIVE The relationship between the adolescent and young adult age groups and poor overall survival in soft tissue sarcoma and the risk factors for poor outcomes in adolescent and young adult patients with soft tissue sarcoma were analyzed. METHODS The medical records of 7759 Japanese patients diagnosed with soft tissue sarcoma from 2006-13 were accessed from the Bone and Soft Tissue Tumor registry. The epidemiological features of adolescent and young adult patients were compared with those of other age groups. The cancer survival rates were calculated using the Kaplan-Meier method. The prognostic factors for cancer survival were analyzed with the Cox proportional hazards models. The primary endpoint for prognosis was tumor-related death. RESULTS There were 210 children, 1467 adolescent and young adults, 2771 adults and 3311 elderly among the 7759 patients identified with soft tissue sarcoma. Compared with other age groups, the proportions of myxoid/round cell liposarcoma, synovial sarcoma, malignant peripheral nerve sheath tumor, primitive neuroectodermal tumor and rhabdomyosarcoma in adolescent and young adult patients were the highest, but none was significantly more prevalent in adolescent and young adult patients. On multivariate analysis, age was not a prognostic factor for poor cancer survival among adolescent and young adult patients with soft tissue sarcoma. The cancer survival rates of adolescent and young adult patients with malignant peripheral nerve sheath tumor were poorer than those of the other age groups; however, adolescent and young adult age was not a prognostic factor on multivariate analysis in malignant peripheral nerve sheath tumor patients. CONCLUSIONS Our study is the first to investigate soft tissue sarcoma in adolescent and young adult patients using the nationwide Bone and Soft Tissue Tumor registry. Adolescent and young adult age is not a prognostic factor for poor cancer survival among those with soft tissue sarcoma in Japan.

Abstract
BACKGROUND Approximately 10% of the patients with soft tissue sarcoma show metastasis at initial diagnosis, and hence, poorer prognosis. However, the prognostic factors and whether definitive surgery for the primary lesion improves overall survival, especially when complete resection of metastasis is difficult, remain unclear. METHODS This retrospective analysis was based on the Bone and Soft Tissue Tumor Registry in Japan. Patients with soft tissue sarcoma having metastasis at diagnosis were enrolled, excluding those with Ewing's sarcoma, rhabdomyosarcoma and several other sarcomas with unique behavior and treatment strategies. Overall survival was estimated using the Kaplan-Meier method and compared among the common histologic subtypes. Multivariate analysis with the Cox regression model was used to identify the prognostic factors. RESULTS In total, 1184 patients were included, with a median follow-up duration of 10 months (range: 1-83). The median overall survival was 21 months (95% confidence interval: 18.2-23.8). The multivariate analyses indicated that tumor size, grade and histologic subtypes significantly correlated with overall survival. Moreover, surgery for the primary lesion, in addition to surgery for metastases and chemotherapy, showed significant association with better survival. CONCLUSIONS The prognostic factors in patients with metastatic soft tissue sarcoma at diagnosis are generally similar to those in patients with localized disease. The overall survival in patients differed significantly according to histologic subtype. Surgical resection of primary lesions, especially those with a wide margin, may be an independent prognostic factor. Further studies are needed identify which subgroup of patients would benefit the most from primary lesion surgery.

Abstract
BACKGROUND The optimal management of petroclival meningiomas (PCMs) continues to be debated along with several controversies that persist. METHODS A task force was created by the EANS skull base section along with its members and other renowned experts in the field to generate recommendations for the management of these tumors. To achieve this, the task force reviewed in detail the literature in this field and had formal discussions within the group. RESULTS The constituted task force dealt with the existing definitions and classifications, pre-operative radiological investigations, management of small and asymptomatic PCMs, radiosurgery, optimal surgical strategies, multimodal treatment, decision-making, and patient's counselling. CONCLUSION This article represents the consensually derived opinion of the task force with respect to the management of PCMs.

Abstract
OBJECTIVES To determine the incidence of bioprosthetic structural valve deterioration in dialysis patients undergoing aortic valve replacement compared to that in patients without dialysis. METHODS This single-centre retrospective observational study included 1159 patients who underwent aortic valve replacement using bioprosthetic valves for aortic stenosis and/or regurgitation at our institution between 2007 and 2017 [patients with dialysis (group D, n = 134, 12%) or without dialysis (group N, n = 1025, 88%)]. To adjust for potential differences between groups in terms of initial preoperative characteristics or selection bias, a propensity score analysis was conducted. The final sample that was used in the comparison included 258 patients, as follows: 129 patients with dialysis (group D) and 129 patients without dialysis (group N). The cumulative incidences of all-cause death, cardiac death and moderate or severe structural valve deterioration were estimated using the Kaplan-Meier method. RESULTS Operative mortality was significantly higher in group D than group N (9% vs 0%, P = 0.001). Kaplan-Meier analysis revealed that in group D, the incidence was significantly higher for all-cause death (P < 0.001, 50% vs 18% at 5 years), cardiac death (P = 0.001, 18% vs 5% at 5 years) and moderate or severe structural valve deterioration (P < 0.001, 29% vs 5% at 5 years) compared with group N. CONCLUSIONS The incidence of structural valve deterioration in dialysis patients undergoing aortic valve replacement was higher than that in patients without dialysis. Bioprosthetic valves should be carefully selected in dialysis patients undergoing aortic valve replacement.

Abstract
Children and adolescents and young adults (AYAs) with cancer are often treated with a multidisciplinary approach. This includes use of radiotherapy, which is important for local control, but may also cause adverse events in the long term, including second cancer. The risks for limited growth and development, endocrine dysfunction, reduced fertility and second cancer in children and AYAs are reduced by proton beam therapy (PBT), which has a dose distribution that decreases irradiation of normal organs while still targeting the tumor. To define the outcomes and characteristics of PBT in cancer treatment in pediatric and AYA patients, this document was developed by the Japanese Society for Radiation Oncology (JASTRO) and the Japanese Society of Pediatric Hematology/Oncology (JSPHO).

Abstract
BACKGROUND Approximately 10-20% of osteosarcoma patients present with metastasis on diagnosis. Completely resecting the lesion is associated with better prognosis. However, evidence regarding optimal surgical strategies for patients with unresectable metastasis is limited. METHODS This retrospective analysis was based on the Japanese Nationwide Bone and Soft Tissue Tumor registry. In total, 335 patients diagnosed with osteosarcoma with metastasis were included. Factors affecting overall survival were identified using multivariate analysis. Kaplan-Meier method was used to compare the overall survival by the status of surgical intervention. Two hundred and four patients who did not undergo surgery for metastasis were divided into two groups, depending on whether they underwent surgery for the primary lesion. The background differences between these two groups were adjusted with propensity score matching, with 43 patients per group. The overall survival was calculated using the Kaplan-Meier method and compared with a log-rank test. RESULTS Factors positively impacting overall survival were age <40, female sex, extremity origin, surgery for the primary lesions, surgery for metastasis and radiotherapy without surgery. For patients with unresectable metastasis, after propensity score matching, the survival rate was higher in the group that underwent primary lesion surgery than the group without surgery. Their median survival was 19 (95% confidence interval: 11.7-26.3) and 11 months (95% confidence interval: 4.5-17.5) (P = 0.02), respectively. CONCLUSIONS Surgical resection of the primary osteosarcoma lesion did not worsen prognosis, even in patients with unresectable metastasis. Further study is needed to identify which patient group will benefit from primary lesion resection.

Abstract
Biomass may ignite due to biological oxidation and chemical oxidation. If this phenomenon (spontaneous ignition) is controlled, it would be possible to produce biochar at a lower cost without the need for an external heat resource. We investigated if self-heating could be controlled by using sawdust and bark chips. When sawdust and bark chips were used under controlled conditions, the bark chips temperature increased to the torrefaction temperature. The ash content of bark chips was ~ 2%d.b. higher than that of sawdust; consequently, the inorganic substances contained in the bark chips might affect the self-heating. Self-heating was suppressed when inorganic substances were removed by washing with water. Therefore, the inorganic substances in the biomass might have affected self-heating. The inorganic element contents of the bark chips were measured by inductively coupled plasma optical emission spectrometry before and after washing. The potassium content of the bark chips was reduced remarkably by washing, and there was a possible influence of potassium on self-heating. Finally, the effect of moisture content on self-heating was investigated to obtain stable reactivity. Thus, at a moisture content of 40%w.b., a steady self-heating behavior may be realized.

Abstract
PURPOSE The aim of this study is to reveal the vascular branching variation in SFC (splenic flexure cancer) patients using the preoperative three-dimensional computed tomography angiography with colonography (3D-CTAC). METHODS We retrospectively analyzed patients with SFC who underwent preoperative 3D-CTAC between January 2014 and December 2019. RESULTS Among 1256 colorectal cancer (CRC) patients, 96 (7.6%) manifested SFC. The arterial branching from the superior mesenteric artery (SMA) was classified into five patterns, as follows: (type 1A) the left branch of middle colic artery (LMCA) diverged from middle colic artery (MCA) (N = 47, 49.0%); (2A) the LMCA diverged from the MCA and the accessory middle colic artery (AMCA) (N = 26, 27.1%); (3A) the LMCA independently diverged from the SMA (N = 16, 16.7%); (4A) the LMCA independently diverged from the SMA and AMCA (N = 3, 3.1%); (5A) only the AMCA and the LMCA was absent (N = 4, 4.1%). Venous drainage was classified into four patterns, as follows: (type 1V) the SFV flows into the inferior mesenteric vein (IMV) then back to the splenic vein (N = 50, 52.1%); (2V) the SFV flows into the IMV then back to the superior mesenteric vein (SMV) (N = 19, 19.8%); (type 3V) the SFV independently flows into the splenic vein (N = 3, 3.1%); (type 4V) the SFV is absent (N = 24, 25.0%). CONCLUSION 3D-CTAC could reveal accurate preoperative tumor localization and vascular branching. These classifications should be helpful in performing accurate complete mesocolic excision and central vessel ligation for SFC.

Abstract
Sendai virus (SeV) vectors are being recognized as a superior tool for gene transfer. Here, we report the transfection efficacy of a novel, high-performance, replication-defective, and persistent Sendai virus (SeVdp) vector in cultured cells and in mice using a near-infrared fluorescent protein (iRFP)-mediated in vivo imaging system. The novel SeVdp vector established persistent infection, and strong expression of inserted genes was sustained indefinitely in vitro. Analysis of iRFP-expressing cells transplanted subcutaneously into NOG, nude, and ICR mice suggests that innate immunity was involved in the exclusion of the transplanted cells. We also evaluated the feasibility of this novel SeVdp vector for hemophilia A gene therapy. This system enabled insertion of full-length FVIII genes, and transduced cells secreted FVIII into the culture medium. Transient FVIII activity was detected in the plasma of mice after intraperitoneal transplantation of these FVIII-secreting cells. Further improvement in methods to evade immunity, such as simultaneous expression of immunomodulatory genes, would make this novel vector a very useful tool in regenerative medicine.

Abstract
Abstract
BACKGROUND
Medulloblastoma (MB) is the most common malignant brain tumor of childhood. MB easily disseminates through the spinal fluid. Surgery followed by radiotherapy, applied to the entire craniospinal axis (CSI), and adjuvant chemotherapy, represent the treatment of choice for patients aged ≥3 years. Since the bone marrow of the skull and vertebral column are the major hematopoietic organs, we investigated the myelosuppressive effect of irradiation treatment in patients with MB retrospectively.
METHODS
Medical records of newly diagnosed MB patients treated at our hospital from 2007–2019 were analyzed. Children <3 years old were excluded because they did not receive CSI to avoid potential neurotoxicity.
RESULTS
Medical records of 18 patients (11 males and 7 females, aged 6–26, median 11 years) were reviewed. Eight patients were stratified as high-risk disease and 10 patients with standard risk. All patients received CSI (dosage range 23.4–39.6 Gy based on disease risk) and posterior fossa boost. All patients developed lymphocytopenia (<0.5×109/L) during irradiation, and for 11 of 18 patients, lymphocytopenia (<0.2×109/L) was severe. Although 13 patients recovered from the lymphocytopenia before the initiation of chemotherapy, five patients underwent chemotherapy without recovery. Conversely, only six patients developed neutropenia (<1.0×109/L), and five of the six patients were <10 years old.
CONCLUSION
Although infectious episode associated with lymphocytopenia was not observed in this study, CSI treatment in children and adolescents may induce immunodeficient condition particularly in the lymphocytic system. Pediatric oncologists should pay attention to the impaired immunity of patients with MB who receive CSI.

Abstract
Background This study compared the clinical results for nonporous stems vs. trabecular metal (TM) stems used in reverse shoulder arthroplasty (RSA) for comminuted proximal humeral fractures (CPHFs) in elderly patients. Methods In this retrospective study, a total of 41 shoulders (39 women) of patients with CPHF aged >70 years who underwent RSA were investigated. The minimum follow-up period was 2 years. A total of 15 shoulders were treated with Grammont-style RSA using nonporous stems (the G-RSA group), and 26 shoulders were treated with RSA combining TM stems (the FR-RSA group). The American Shoulder and Elbow Surgeons (ASES) shoulder score, Constant score, shoulder joint range of motion (ROM), and radiographic findings were compared between the 2 groups. Results ASES scores and Constant scores were significantly higher in the FR-RSA group than in the G-RSA group. External rotation at the side in the FR-RSA group was significantly higher than that in the G-RSA group. In the FR-RSA and G-RSA groups, the union rates at the greater tuberosity (GT) were 88.5% and 46.7%, respectively, and scapular notching rates were 20% and 7.7%, respectively. Based on a subanalysis, the age was lower, body mass index was higher, and ASES scores, Constant scores, and external rotation ROM were higher in the GT union group than in the GT nonunion group. Conclusion GT bone union rates were high, and external rotation ROM of the shoulder joint were more improved for RSA using TM stems than those for RSA using nonporous stems in elderly patients with CPHF.

Abstract
A 45-year-old male developed Stanford type A acute aortic dissection combined with aortic root dilation and congenital bicuspid aortic valve (BAV). He had a Sieveres type 0 BAV, lateral subtype with right and left cusps. Valve-sparing root reimplantation was performed with decalcification of the cusps. Transthoracic echocardiography(TTE) at discharge revealed no aortic regurgitation, and peak velocity of BAV was 2.15 m/second, mean pressure gradient was 9.6 mmHg and aortic valve area was 2.15 cm2. TTE after 6 months revealed only slight elevation of the peak velocity to 2.78 m/second. To perform successful reimplantation in the case of BAV, anatomic orientation of the cusps should be approximately at 180° and the tissue of the cusps should either be normal or have only minor abnormalities. Valve-sparing root reimplantation for BAV needs a careful follow-up for progression of the aortic valve dysfunction.

Abstract
Immunophenotyping was performed in 1044 consecutive childhood acute lymphoblastic leukemia (ALL) patients enrolled in the Tokyo Children's Cancer Study Group L04-16 trial, revealing novel findings associated with genetic abnormalities. In addition to TCF3-PBX1 and MEF2D fusions, the CD10(+) subtype of KMT2A-MLLT3-positive ALL frequently exhibited the cytoplasmic-μ(+) pre-B ALL immunophenotype. Although ETV6-RUNX1 was significantly correlated with myeloid antigen expression, more than half of patients expressed neither CD33 nor CD13, while the CD27(+) /CD44(-) immunophenotype was maintained. Expression of CD117 and CD56 in B-cell precursor-ALL was limited to certain subtypes including ETV6-RUNX1 and KMT2A-MLLT3. Besides BCR-ABL1, CRLF2, hyperdiploidy, and hypodiploidy, CD66c was also expressed in Ph-like kinase fusion-, PAX5 fusion-, and DUX4 fusion-positive ALL, but not in MEF2D fusion-positive ALL, indicating constant selectivity of CD66c expression. In T-ALL, SIL-TAL1-positive patients were likely to exhibit a more mature immunophenotype. Expression of CD21 and CD10 was not rare in T-ALL, while lack of CD28 was an additional feature of early T-cell precursor-ALL. Considering the immunophenotype as a prognostic maker, MEF2D fusion-positive ALL with CD5 expression may be associated with a poorer prognosis in comparison with those lacking CD5 expression. In cases with characteristic marker expression, the presence of certain fusion transcripts could be predicted accurately.

Abstract
Three cases of para-articular osteochondroma, a rare benign disease, are presented. Symptoms at presentation included chronic knee pain and limited knee movement. Simple marginal resection using an open approach was performed. Post-surgery, the pain disappeared and the range of motion of the knee was restored.
Introduction Para-articular osteochondromas are not very common. We performed simple marginal excision for three cases. Presentation of case We encountered three cases of para-articular osteochondroma of the infrapatellar fat pad. All patients were men, with an average age of 43 years. The symptoms were very similar to those of anterior knee pain, which were increasing swelling and reduction of the range of motion. After simple marginal excision was performed, the symptoms improved and no recurrences or malignant transformation occurred during the mean postoperative period of 51 months. Discussion Forty-seven cases of para-articular osteochondroma have been reported, and excision is the standard treatment. Local recurrence has been reported in only one case, and malignant transformation has never been reported. However, in some reports there was no specification of the excision method, which was simply referred to as “excision.” Thus, we used a simple marginal excision for all three of our cases. Conclusion We report three cases of para-articular osteochondroma of the infrapatellar fat pad that were effectively treated using simple marginal excision.

Abstract
Abstract
The involvement of cholesterol crystals (CCs) in plaque progression and destabilization of atherosclerotic plaques has been recently recognized. However, little is known about CCs and myocardial salvage in the Acute myocardial infarction (AMI) patients. This study aimed to evaluate the association between the existence of CCs at the site of culprit coronary artery and myocardial salvage index (MSI).To investigate, we applied the diagnostic resources of Optical Coherence Tomography (OCT).
Methods
This study included 53 AMI patients (90% with STEMI) who underwent primary PCI within 24h of onset. 53 STEMI patients underwent magnetic resonance imaging (CMR) of 5th days and 3 months after PCI. Infarct size was measured on delayed-enhancement imaging, and area at risk was quantified on T2-weighted imaging. MSI was calculated as [area at risk − infarct size] × 100/area at risk. 3 months CMR with contrast-enhanced imaging of late gadolinium enhancement-LGE. Patients were divided 2 groups according to the existence of CCs at the site of culprit coronary artery.
Results
CCs occurs in 26 of 53 (49%). Acute 5th days risk area (13.5±4.1 vs 12.6±4.9, P=0.48) and 3months infarct size (5.3±3.5 vs 7.0±3.2, P=0.066) were not significant between CCs and no CCs group. But salvage index were significantly lower in patients with CCs group (47.7±17.5% vs 60.1±20.2%, P=0.021)
Conclusion
Salvage index in patients that CCs were found by the OCT analysis, remain low after AMI. This study demonstrates the potential correlation between the myocardial salvage and vulnerable morphological features of culprit lesion to the presence of CCs with AMI patients.

Abstract
t(17;19)(q21‐q22;p13), responsible for TCF3‐HLF fusion, is a rare translocation in childhood B‐cell precursor acute lymphoblastic leukemia(BCP‐ALL). t(1;19)(q23;p13), producing TCF3‐PBX1 fusion, is a common translocation in childhood BCP‐ALL. Prognosis of t(17;19)‐ALL is extremely poor, while that of t(1;19)‐ALL has recently improved dramatically in intensified chemotherapy. In this study, TCF3‐HLF mRNA was detectable at a high level during induction therapy in a newly diagnosed t(17;19)‐ALL case, while TCF3‐PBX1 mRNA was undetectable at the end of induction therapy in most newly diagnosed t(1;19)‐ALL cases. Using 4 t(17;19)‐ALL and 16 t(1;19)‐ALL cell lines, drug response profiling was analyzed. t(17;19)‐ALL cell lines were found to be significantly more resistant to vincristine (VCR), daunorubicin (DNR), and prednisolone (Pred) than t(1;19)‐ALL cell lines. Sensitivities to three (Pred, VCR, and l‐asparaginase [l‐Asp]), four (Pred, VCR, l‐Asp, and DNR) and five (Pred, VCR, l‐Asp, DNR, and cyclophosphamide) agents, widely used in induction therapy, were significantly poorer for t(17;19)‐ALL cell lines than for t(1;19)‐ALL cell lines. Consistent with poor responses to VCR and DNR, gene and protein expression levels of P‐glycoprotein (P‐gp) were higher in t(17;19)‐ALL cell lines than in t(1;19)‐ALL cell lines. Inhibitors for P‐gp sensitized P‐gp‐positive t(17;19)‐ALL cell lines to VCR and DNR. Knockout of P‐gp by CRISPRCas9 overcame resistance to VCR and DNR in the P‐gp‐positive t(17;19)‐ALL cell line. A combination of cyclosporine A with DNR prolonged survival of NSG mice inoculated with P‐gp‐positive t(17;19)‐ALL cell line. These findings indicate involvement of P‐gp in resistance to VCR and DNR in Pgp positive t(17;19)‐ALL cell lines. In all four t(17;19)‐ALL cell lines, RAS pathway mutation was detected. Furthermore, among 16 t(1;19)‐ALL cell lines, multiagent resistance was usually observed in the cell lines with RAS pathway mutation in comparison to those without it, suggesting at least a partial involvement of RAS pathway mutation in multiagent resistance of t(17;19)‐ALL.

Abstract
Although the presence of chronic total occlusion (CTO) has been associated with long-term mortality in the patients with ST-segment elevation myocardial infarction, the influence of having CTO on in-hospital mortality in sudden cardiac arrest (SCA)-acute coronary syndrome (ACS) patients has not been reported. Therefore, we examined the association between the presence of CTO and in-hospital mortality in those patients. Consecutive 106 SCA-ACS patients who received coronary angiography were retrospectively included. The factors associated with in-hospital mortality were analyzed. Among 106 patients, 40 (38%) patients died during hospitalization. Multivariate analysis revealed presence of CTO dependent on infarct-related artery (IRA-dependent-CTO) (hazard ratio [HR] = 2.88, p = 0.004), diabetes mellitus (HR = 2.04, p = 0.044), percutaneous cardiopulmonary support use (HR = 2.22, p = 0.045), successful recanalization (HR = 0.31, p = 0.004), and peak creatine kinase muscle-brain fraction (HR = 1.11, p < 0.001) were significantly associated with mortality. In conclusion, presence of IRA-dependent-CTO was significantly associated with in-hospital mortality in SCA-ACS patients.

Abstract
CHARGE syndrome is a rare congenital malformation syndrome which may share symptoms with DiGeorge syndrome. Complete DiGeorge syndrome (cDGS) is a severe form of DiGeorge syndrome, characterized by a CD3+ T-cell count of <50/mm3 due to athymia, and is fatal without immunologic intervention. We performed peripheral blood lymphocyte transfusion (PBLT) from an HLA-identical sibling without pretransplant conditioning in a CHARGE/cDGS patient with a novel CHD7 splice site mutation. Cyclosporine and short-term methotrexate were used for graft versus host disease (GVHD) prophylaxis, and neither acute nor chronic GVHD was observed. After PBLT, T-cell proliferative response to phytohemagglutinin and concanavalin A recovered, and intractable diarrhea improved. EBV infection, evidenced by a gradual increase in the viral genome copy number to a maximum of 2861 copies/μgDNA on day 42 after PBLT, resolved spontaneously. HLA A2402 restricted, EBV-specific CTLs were detected from peripheral blood on day 148, and EBV seroconversion was observed on day 181. Thus, EBV-specific immunity was successfully established by PBLT. Our results indicate that PBLT is a simple and effective therapy to reconstitute immune systems in CHARGE/DiGeorge syndrome.

Abstract
OBJECTIVES An operations leader (OL) takes an important role in occupational health management for radiation decontamination workers in Japan, and candidates for the position must participate in a training session to acquire the necessary knowledge as required by law. However, it has not been clarified whether the candidates for the OL position actually possess accurate knowledge regarding occupational health management for such work after the training session. We, therefore, aimed at examining the current occupational health management knowledge among the candidates and investigating factors related to the knowledge, with hypothesis that possession of accurate knowledge is associated with prior experience of having worked in radiation decontamination. DESIGN A cross-sectional study. SETTING The training sessions held by Fukushima Prefecture Labor Standard Associations in Fukushima, Japan, in 2017. PARTICIPANTS Eighty male candidates participated in the training sessions. OUTCOME The number/proportion of correct answers to the questions regarding occupational health management, such as those on working environment management, control of operations and health management. RESULTS The proportion of those who possessed accurate knowledge regarding working environment management, control of operations and health management was 68.8%, 55.0% and 51.2%, respectively. Experience of radiation decontamination work was associated with the possession of inaccurate knowledge regarding working environment management (OR 0.140 (95% CI 0.042 to 0.464)), and the uncertainty of future radiation decontamination work schedules in difficult-to-return zones was associated with the possession of accurate knowledge regarding health management (OR 4.344 (95% CI 1.509 to 12.50)). CONCLUSIONS Previous experience in radiation decontamination work may hinder the ability to acquire accurate information regarding working environment management among candidates for an OL position. To promote adequate occupational health management for radiation decontamination workers, it is required to establish an effective instructional method for the OL candidate training sessions with consideration of previous relevant experience.

Abstract
Background Schwannomas are well-encapsulated, benign neoplasms, and enucleation is a standard operation procedure. The incidence of neurological complications after surgical treatment for schwannomas of the extremities varies, and there is no consensus concerning predictive factors for complications. The aim of this study was to elucidate predictive factors for complications after surgical treatment of schwannomas that develop in the major nerves of the extremities. Methods A total of 139 patients with 141 schwannomas arising in major nerves were retrospectively analyzed. Data regarding preoperative clinical features, the postoperative neurological complications, and clinical course of complications, with a median follow-up period of 2 months (range, 0.5–96), were obtained. Predictive factors for complications were statistically analyzed. Results Postoperative complications occurred in 49 lesions (34.8%), including 42 with sensory disturbance and 8 with motor weakness. In univariate analysis, older age, tumors originating from the upper extremity, and major motor nerve involvement were associated with a higher complication rate (p = 0.03, p = 0.003, and p = 0.001, respectively). In multivariate analysis, major motor nerve involvement was an independent predictive factor for postoperative complications (p = 0.03). Almost all complications gradually improved, but 6 out of 8 patients with motor weakness did not show full recovery at the final follow-up. Conclusions Schwannomas originating from major motor nerves can lead to a higher risk for postoperative complications.

Abstract
Electrochemical hydrogenation of a carboxylic acid using water as a hydrogen source is an environmentally friendly synthetic process for upgrading bio-based chemicals. We systematically studied electrochemical hydrogenation of non-aromatic carboxylic acid derivatives on anatase TiO2 by a combination of experimental analyses and density functional theory calculations, which for the first time shed light on mechanistic insights for the electrochemical hydrogenation of carboxylic acids. Development of a substrate permeable TiO2 cathode enabled construction of a flow-type electrolyser, i.e., a so-called polymer electrode alcohol synthesis cell (PEAEC) for the continuous synthesis of an alcoholic compound from a carboxylic acid. We demonstrated the highly efficient and selective conversion of oxalic acid to produce glycolic acid, which can be regarded as direct electric power storage into an easily treatable alcoholic compound.

Abstract
BACKGROUND Whether arthrodesis is necessary to correct equinovarus associated with myelodysplasia in children, possibly preventing its recurrence, is controversial. At our hospital, patients >4 years of age with equinovarus associated with myelodysplasia are treated with posteromedial release combined with arthrodesis of the talocalcaneal and calcaneocuboid joints. This retrospective study aimed to reinvestigate the postoperative outcomes of this surgery. METHODS The outcomes were evaluated by clinically assessing patients' records according to de Carvalho Neto and Machida, focusing on related complications, union rate after arthrodesis in talocalcaneal and calcaneocuboid joints, evidence of osteoarthritis in the talocrural joint, and the angle of the ankle joint on plain radiographs at the final follow-up >1 year postoperatively. RESULTS We evaluated 12 feet from nine patients. The mean age at the time of surgery was 5 years, and the mean follow-up was 78 months. The clinical assessment according to de Carvalho Neto et al. was "good" in 10 cases and "fair" in 2 cases. The Machida et al. assessment was "excellent" in 5 cases, "good" in 2 cases, and "fair" in 5 cases. One fracture occurred in a single proximal tibia (8%). Union rate after arthrodesis was 83% in the talocalcaneal joint and 42% in the calcaneocuboid joint. There was no evidence of osteoarthritis in the talocrural joint. Postoperative tibiocalcaneal (TiCa) and tibiotalor (TiTa) angles, measured in maximum dorsiflexion, were significantly smaller than the preoperative angles (p = 0.01 for both). Postoperative TiCa and TiTa angles measured in maximum plantar flexion minus the TiCa and TiTa angles measured in maximum dorsiflexion were not significantly less than the preoperative angles (p = 0.23 and 0.62, respectively). CONCLUSION Our surgical outcomes were generally good. However, we must monitor the patients for recurrence because of the relatively low 42% union rate of the calcaneocuboid joint.

Abstract
Fusion genes involving MEF2D have recently been identified in precursor B-cell acute lymphoblastic leukemia, mutually exclusive of the common risk stratifying genetic abnormalities, although their true incidence and associated clinical characteristics remain unknown. We identified 16 cases of acute lymphoblastic leukemia and 1 of lymphoma harboring MEF2D fusions, including MEF2D-BCL9 (n=10), MEF2D-HNRNPUL1 (n=6), and one novel MEF2D-HNRNPH1 fusion. The incidence of MEF2D fusions overall was 2.4% among consecutive precursor B-cell acute lymphoblastic leukemia patients enrolled onto a single clinical trial. They frequently showed a cytoplasmic μ chain-positive pre-B immunophenotype, and often expressed an aberrant CD5 antigen. Besides up- and down-regulation of HDAC9 and MEF2C, elevated GATA3 expression was also a characteristic feature of MEF2D fusion-positive patients. Mutations of PHF6, recurrent in T-cell acute lymphoblastic leukemia, also showed an unexpectedly high frequency (50%) in these patients. MEF2D fusion-positive patients were older (median age 9 years) with elevated WBC counts (median: 27,300/ml) at presentation and, as a result, were mostly classified as NCI high risk. Although they responded well to steroid treatment, MEF2D fusion-positive patients showed a significantly worse outcome, with 53.3% relapse and subsequent death. Stem cell transplantation was ineffective as salvage therapy. Interestingly, relapse was frequently associated with the presence of CDKN2A/CDKN2B gene deletions. Our observations indicate that MEF2D fusions comprise a distinct subgroup of precursor B-cell acute lymphoblastic leukemia with a characteristic immunophenotype and gene expression signature, associated with distinct clinical features.
