Abstract
BACKGROUND Soft-tissue metastasis of carcinoma is rare. In the present study, we investigated the surgical indications and clinical features of patients with soft tissue metastases of carcinoma. METHODS In this retrospective cohort study, we enrolled 26 patients with soft tissue carcinoma metastasis referred to our department for treatment. Sex, age, location, size, depth, pain due to the tumor, primary origin, serum C-reactive protein (CRP) level, MRI examinations, diagnosis by a previous physician, carcinoma markers from blood, history of carcinoma, other metastases, performance status (PS), and surgical procedures were documented. Associations between variables and surgery were statistically analyzed. RESULTS The primary cancer origin was found to be the lung (n = 10), kidney (n = 7), esophagus (n = 2), stomach (n = 1), breast (n = 1), liver (n = 1), ureter (n = 1), anus (n = 1), and unknown (n = 2). The mean CRP level of all patients was 2.3 mg/dL. Seven tumors (26.9%) were originally suspected to be soft tissue metastases of carcinoma, while 19 tumors (73.1%) were considered soft tissue sarcomas or inflammatory lesions by the previous treating physician. Twenty patients (76.9%) had other metastases. The PS of the 12 patients (46.2%) was zero. Eleven patients (42.3%) underwent surgery for soft tissue metastases. Diagnosis of soft tissue metastasis by a previous physician and good PS (p < 0.05) were significantly associated with surgery. CONCLUSION Overall, the present results show that surgical indications for soft tissue metastasis of carcinoma include diagnosis by the referring physician or good PS of the patients.

Abstract
Aims Surgical site infection (SSI) after soft-tissue sarcoma (STS) resection is a serious complication. The purpose of this retrospective study was to investigate the risk factors for SSI after STS resection, and to develop a nomogram that allows patient-specific risk assessment. Methods A total of 547 patients with STS who underwent tumour resection between 2005 and 2021 were divided into a development cohort and a validation cohort. In the development cohort of 402 patients, the least absolute shrinkage and selection operator (LASSO) regression model was used to screen possible risk factors of SSI. To select risk factors and construct the prediction nomogram, multivariate logistic regression was used. The predictive power of the nomogram was evaluated by receiver operating curve (ROC) analysis in the validation cohort of 145 patients. Results LASSO regression analysis selected possible risk factors for SSI, including age, diabetes, operating time, skin graft or flap, resected tumour size, smoking, and radiation therapy. Multivariate analysis revealed that age, diabetes, smoking during the previous year, operating time, and radiation therapy were independent risk factors for SSI. A nomogram was developed based on the results of multivariate logistic regression analysis. In the development cohort, the incidence of SSI was 4.5% in the low-risk group (risk score < 6.89) and 26.6% in the high-risk group (risk score ≥ 6.89; p < 0.001). In the validation cohort, the incidence of SSI was 2.0% in the low-risk group and 15.9% in the high-risk group (p = 0.004). Conclusion Our nomogram will enable surgeons to assess the risk of SSI in patients with STS. In patients with high risk of SSI, frequent monitoring and aggressive interventions should be considered to prevent this.

Abstract
BACKGROUND The objective of this study is to examine the relation between the perceived discrimination suffered by older adults aged 60 and over during a healthcare encounter and its effects on the likelihood of falling 4 and 8 years later. METHODS To identify discrimination, we used the English Longitudinal Study of Ageing (ELSA) data collected in 2010-2011 (wave 5) that asked respondents about feeling discriminated against by doctors or at hospitals in the past year. Falls were assessed by the question: "Have you fallen down in the last two years?" in subsequent waves. We performed longitudinal analyses using the 2014-2015 (wave 7) and 2018-2019 (wave 9) follow-ups. Multivariable logistic regression was used to estimate the odds ratios of falling. RESULTS At baseline, 707 (15.1%) of all respondents experienced healthcare discrimination. Those suffering from discrimination in health care had 64% higher chances of falling 4 years later (odds ratio: 1.637, 95% confidence interval: 1.131-2.368) compared to those who did not, adjusting for age, sex, marital status, wealth, ethnicity, education levels, self-perceived health, depressive symptoms, and difficulties with basic and/or instrumental activities of daily living (ADL/IADL) and difficulties with walking. After 8 years, the effect was not statistically significant. Older age was the only significant detrimental factor at both 4 and 8 years. CONCLUSIONS Understanding discrimination in health care is important to enable safe and welcoming environments for the timely future use of services. These results remind us of the physical risk and the complex panorama of bio-psychosocial determinants involved in tackling discrimination over time.

Abstract
Objectives We aimed to describe patient characteristics, healthcare utilization, and in-hospital mortality among patients with COVID-19 in Japan across waves. Methods Using a large-scale hospital-based database, we identified patients hospitalized for COVID-19 in the first (January-June 2020), second (June-October 2020), third (October 2020-February 2021), fourth (March-June 2021), and fifth (June-December 2021) waves. We summarized patient characteristics, healthcare utilization, and in-hospital mortality during each wave and performed multivariable logistic regression analyses for in-hospital mortality. Results From the first to fifth waves, the number of patients (mean age ± standard deviation, years) was 2958 (61.2 ± 22.8), 7981 (55.6 ± 25.3), 18,788 (63.6 ± 22.9), 17,729 (60.6 ± 22.6), and 23,656 (51.2 ± 22.3), respectively. There were 190 (6.4%), 363 (4.5%), 1261 (6.7%), 1081 (6.1%), and 762 (3.2%) in-hospital deaths, respectively. The adjusted odds ratios for in-hospital deaths (95% confidence interval) were 0.78 (0.65-0.95), 0.94 (0.79-1.12), 0.99 (0.84-1.18), 0.77 (0.65-0.92), in the second to fifth waves, respectively, compared with the first wave. Conclusions In-hospital COVID-19 mortality improved from the first to the second wave; however, during the third and fourth waves, mortality was as serious as in the first wave. Although in-hospital mortality during the fifth wave improved, careful monitoring is needed for upcoming waves, considering changing patient and viral characteristics.

Abstract
Giant cell tumors of bone (GCTB) sometimes metastasize to distant organs. In this case report, we present pulmonary metastases of GCTB mimicking malignancies. A 49-year-old man underwent two surgical treatments for a GCTB of the right proximal radius. At the time of the second surgery, no lesions were observed on chest radiography. Three years after surgery, the patient presented with cough and dyspnea, and chest radiography and computed tomography (CT) revealed multiple lung nodules. Positron emission tomography/CT revealed a high accumulation of 18F-fluoro-2-deoxy-D-glucose (18F-FDG) in multiple lesions. Based on the rapid growth and accumulation of 18F-FDG, a metastatic malignant tumor was suspected. CT-guided needle biopsy was performed, and the histology showed proliferation of spindle cells and multinuclear giant cells without malignant changes. Denosumab was administered because multiple lung lesions were unresectable. One month after denosumab treatment, CT showed marked shrinkage of the lesions, and the symptoms significantly improved. Eighteen months after the initial treatment with denosumab, the patient had no symptoms or tumor growth. Although its long-term efficacy and safety remain unclear, denosumab may be a treatment option for patients with unresectable pulmonary GCTB.

Abstract
Tumor-bearing frozen autografts have been widely used for reconstruction of bone defects caused by tumor resection. However, some patients undergo removal of the grafted bone due to surgical site infection, tumor recurrence, or fractures of the grafted bone. In this retrospective cohort study, predictive factors for graft survival were investigated in 123 patients who underwent reconstructions using a tumor-bearing frozen autograft after bone tumor resection of the extremities. To determine the independent predictors of graft survival, the association between various parameters and graft survival was investigated. The graft survival rates were 83.2% at 5 years and 70.2% at 10 years. Among the 123 frozen autografts, 25 (20.3%) were removed because of complications. In univariate analyses, male sex, BMI of ≥23.6, tibia, and chemotherapy were significantly associated with poor graft survival, whereas the pedicle/hemicortical freezing procedure was significantly associated with better graft survival. Multivariate analysis using the Cox proportional hazards regression model revealed that BMI of ≥23.6 (HR, 3.4; p = 0.005), tibia (HR, 2.3; p = 0.047), and freezing procedure (HR, 0.3; p = 0.016) were independently associated with graft survival. Based on the results, pedicle or hemicortical freezing techniques are recommended in cases where these techniques can be applied.

Abstract
BACKGROUND A sclerosing epithelioid fibrosarcoma (SEF) is an uncommon tumor of the deep soft tissue. An SEF has been described as a low-grade tumor with high local recurrence and metastatic rates. Generally, in bone and soft tissue tumors, a resection of the biopsy route is recommended; however, there is limited evidence with respect to the dissemination of the tumor tissue during a needle biopsy. CASE PRESENTATION A mass in the right pelvic cavity, with no symptoms, was observed in a 45-year-old woman during a gynecological examination. Computed tomography (CT) revealed a multilocular mass with calcification in the pelvic cavity. The magnetic resonance imaging (MRI) showed an iso-signal intensity on T1 weighted images and hypo- and iso-signal intensity on T2 weighted images. The CT-guided core needle biopsy was performed using a dorsal approach, and the biopsy diagnosis was a low-grade spindle cell tumor. The tumor was excised using an anterior approach. The tumor tissue comprised spindle cells and epithelioid cells with irregular nuclei, and the immunohistological analysis was positive for vimentin and epithelial membrane antigen, which was consistent with a diagnosis of sclerosing epithelioid fibrosarcoma. Five years after the surgery, the MRI showed a tumor recurrence in the subcutaneous tissue of the right buttock, which was consistent with the needle biopsy tract. The patient underwent a tumor excision, and the resected tumor was similar to the primary tumor. CONCLUSIONS The recurrent tumor was excised with a surgical margin, and the tumor specimen had the histological features of a sclerosing epithelioid fibrosarcoma. It was difficult to investigate the association of the core needle biopsy with the tumor recurrence because the approach of the biopsy tract is usually same as that used in a tumor excision. However, the present case indicated the tumor may recur in the biopsy tract of a soft tissue sarcoma. Surgeons should be aware of the possibility of disseminating tumor tissues in a needle biopsy.

Abstract
In our previous study, osteosarcoma advanced locally, and metastasis was promoted through the secretion of large number of small extracellular vesicles, followed by suppressing osteoclastogenesis via the upregulation of microRNA (miR)-146a-5p. An additional 12 miRNAs in small extracellular vesicles were also detected ≥6× as frequently in high-grade malignancy with the capacity to metastasize as in those with a low metastatic potential. However, the utility of these 13 miRNAs for determining the prognosis or diagnosis of osteosarcoma has not been validated in the clinical setting. In the present study, the utility of these miRNAs as prognostic and diagnostic markers was therefore assessed. In total, 30 patients with osteosarcoma were retrospectively reviewed, and the survival rate was compared according to the serum miRNA levels in 27 patients treated with chemotherapy and surgery. In addition, to confirm diagnostic competency for osteosarcoma, the serum miRNA levels were compared with those in patients with other bone tumors (n=112) and healthy controls (n=275). The patients with osteosarcoma with high serum levels of several miRNAs (miR-146a-5p, miR-1260a, miR-487b-3p, miR-1260b and miR-4758-3p) exhibited an improved survival rate compared with those with low levels. In particular, patients with high serum levels of miR-1260a exhibited a significantly improved overall survival rate, metastasis-free survival rate and disease-free survival rate compared with those with low levels. Thus, serum miR-1260a may potentially be a prognostic marker for patients with osteosarcoma. Moreover, patients with osteosarcoma had higher serum miR-1261 levels than those with benign or intermediate-grade bone tumors and thus may be a potential therapeutic target, in addition to being useful for differentiating whether or not a bone tumor is high-grade. A larger investigation is required to clarify the actual utility of these miRNAs in the clinical setting.

Abstract
BACKGROUND/AIM Amputation is still a viable option for musculoskeletal tumors that are multi-compartmental, adjacent to neurovascular structures, and involving pathological fractures. Complications such as poor surgical margins, local recurrence and infection after limb salvage surgery are also indications for secondary amputation. An effective hemostatic technique is vital for preventing complications of massive blood loss and prolonged operative time. The use of LigaSure™ in the field of musculoskeletal oncology has not been well documented. PATIENTS AND METHODS This retrospective study included 27 patients with musculoskeletal tumor who underwent amputation using either LigaSure™ system (n=12) or traditional hemostatic technique (n=15) from 1999 to 2020. The purpose of this study was to evaluate the effect of LigaSure™ in terms of intra-operative blood loss, blood transfusion rates, and duration of surgery. RESULTS The use of LigaSure™ resulted in a significant decrease in intraoperative blood loss (p=0.027) and blood transfusion rates (p=0.020). There was no significant difference for the duration of surgery between the two groups (p=0.634). CONCLUSION The LigaSure™ system can potentially improve clinical outcomes in patients with musculoskeletal tumor undergoing amputation surgeries. The LigaSure™ system is a safe and effective hemostatic tool for musculoskeletal tumor amputation surgeries.

Abstract
BACKGROUND/AIM Kimura's disease is a rare chronic inflammatory disorder that commonly affects the head and neck regions, occurring predominantly in Asian men. Elevated eosinophil count and IgE levels in the peripheral blood examination are suggestive of this disease. In this study we report two cases of Kimura's disease, treated with wide excision. CASE REPORT The first case was a 58-year-old man presented with asymptomatic left neck mass. The second case was a 69-year-old man with swelling of the right upper arm, which was suggestive of soft tissue mass. Needle biopsy results were suggestive of Kimura's disease in both cases. Elevated WBCs at 8,380/μl (neutrophils: 45%, eosinophils: 33%) for the first case and 5,370/μl (neutrophils: 61.8%, eosinophils: 3.5%) for the second one, and serum IgE at 14.988 IU/ml for the first case and 1,315 IU/ml for the second one were observ. For definitive treatment and diagnosis, wide excisions were performed. Final histopathological results revealed Kimura's disease. Surgical margins were negative even though an ill-demarcated lesion for the first case and high infiltration to the muscle for second case were confirmed. CONCLUSION Wide excision was performed in both cases of Kimura's disease and no recurrence was observed until the final follow-up. Wide excision with negative surgical margin should be recommended for the treatment of Kimura's disease.

Abstract
Calcium phosphate cement (CPC) is often used to repair bone defects that occur after bone tumor and fracture treatment. To address bone defect cases with a high infection risk, developing CPCs with a longlasting wide-spectrum antibacterial effect is critical. Povidone-iodine has a wide antibacterial spectrum. Though there have been some reports of CPC containing antibiotics, no report of CPC with iodine has been described. In this study, the antibacterial effect and biological reaction of CPC impregnated with iodine was investigated. Iodine release from CPC and bone cement with various iodine contents (2.5, 5, and 20%) was evaluated, and 5 %-iodine CPC retained more iodine than the other CPCs after one week. Antibacterial activity against Staphylococcus aureus and Escherichia coli was also investigated, showing that 5 %-iodine had an antibacterial effect for up to eight weeks. Cytocompatibility was assessed, and 5 %-iodine CPC showed the same amount of fibroblast colony formation as control samples. CPCs with varying iodine contents (0, 5, and 20%) were then inserted into lateral femora of Japanese white rabbits for histological analysis. Osteoconductivity was evaluated using scanning electron microscopy, and hematoxylin-eosin staining. Consecutive bone formation was observed around all CPCs at eight weeks. These results indicate that CPC impregnated with iodine exhibits antimicrobial activity and cytocompatibility, and therefore, it may be effective for bone defect cases with high infection risk.

Abstract
BACKGROUNDS Immune checkpoint inhibitors (ICIs) can significantly prolong the survival of patients with advanced non-small-cell lung cancer (NSCLC); however, few studies on the therapeutic effects of ICIs on bone metastases were performed. METHODS This retrospective study aimed to investigate the therapeutic effects of ICIs and determine predictors of favorable ICI response and prognosis in 55 advanced NSCLC patients with bone metastases who initiated ICI treatment between 2016 and 2019, with a mean follow-up period of 23.2 months. Patients were classified into responders (complete or partial response) and non-responders (stable or progressive disease) according to the MD Anderson Cancer Center (MDA) criteria, and the predictors of therapeutic response were identified using multivariate logistic regression analysis. Furthermore, overall survival from the time of ICI administration to the final follow-up or death was evaluated, and prognostic predictors were identified using Cox proportional hazards regression analysis. RESULTS ICI response rate was 30.9% (complete in three cases, partial in 14). Median survival time was 9.3 months, with 1-year and 2-year survival rates of 40.6% and 19.3%, respectively. Responders survived significantly longer than non-responders (p = 0.03). Based on the receiver operating characteristic curve, the predictive cutoff value of the pretreatment neutrophil-to-lymphocyte ratio (NLR) was 2.1. Multivariate analysis identified female sex (p = 0.03), use of ICIs as first-line therapy (p < 0.01), and NLR <2.1 (p = 0.03) as significant predictors of therapeutic response, whereas concomitant use of a bone-modifying agent (p < 0.01), Katagiri score ≤6 points (p < 0.01), and NLR <2.1 (p = 0.02) were identified as significant predictors of good prognosis. CONCLUSIONS This study identified some novel predictors for favorable therapeutic response and prognosis in advanced NSCLC patients with bone metastases undergoing ICI treatment. Pretreatment NLR less than 2.1 can be considered the most important predictor.

Abstract
OBJECTIVES Accumulating evidence from cross-sectional studies suggests that the serum creatinine-to-cystatin C ratio (CCR) may be a useful biomarker for sarcopenia. This study aimed to assess the cross-sectional and longitudinal associations of CCR with sarcopenia and its parameters in community-dwelling older adults. DESIGN Cross-sectional and longitudinal study. SETTING AND PARTICIPANTS This 6-year prospective cohort study included the repeated measurement data from 1,253 Japanese residents (662 males and 591 females) aged ≥65 years who underwent medical checkups in Kusatsu and Hatoyama, Japan. A total of 4,421 observations were collected. MEASUREMENTS The CCR was grouped into quartiles by sex (Q1-Q4) using Q4 as the reference category. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 algorithm. Skeletal muscle mass index (SMI) measured using segmental multifrequency bioelectrical impedance analysis, handgrip strength (HGS), usual gait speed (UGS), and maximal gait speed (MGS) were measured repeatedly as sarcopenia parameters. The association of the CCR with changes in sarcopenia, SMI, HGS, UGS, and MGS during the 6-year period were analyzed using a generalized linear mixed-effects model. RESULTS The prevalence of sarcopenia at baseline was 13.1% (11.9% in males and 14.5% in females). In a cross-sectional analysis, the CCR quartile was inversely associated with sarcopenia and was positively associated with SMI, HGS, and MGS (P for trend < 0.001). In a longitudinal analysis during the 6 years, a significant increase in sarcopenia in Q2 (B = 1.1% point/year; P = 0.026 for group-by-time interaction) and significant declines in SMI (B = -0.01 kg/m2/year; P = 0.044 for group-by-time interaction) and MGS (B = -0.008 m/sec/year; P = 0.041 for group-by-time interaction) in Q1 were observed compared with Q4. However, the dose-response relationship was significant only for MGS (P = 0.033 for trend). No significant group-by-time interaction was observed for HGS. CCR was not significantly associated with UGS either cross-sectionally or longitudinally. CONCLUSIONS CCR is a useful biomarker regarding the status of sarcopenia. It may be used for sarcopenia screening even in older adults whose physical function is difficult to assess. However, further longitudinal studies are needed to determine whether CCR can be a predictor of future sarcopenia.

Abstract
PURPOSE OF THE REPORT Several methods are used to reconstruct bony defects after malignant tumor excision. Tumor-bearing frozen autograft reconstruction is a biological procedure in which tumor-bearing bone is reused after devitalization with liquid nitrogen to kill tumor cells. The viability of frozen autografts has not been fully evaluated over time. We therefore aimed to evaluate the viability of devitalized bone grafts, using 99m Tc-MDP scintigraphy. PATIENTS AND METHODS Seventy-four patients who underwent frozen autograft reconstruction after the excision of a malignant bone tumor were enrolled. Two hundred forty-two postoperative 99m Tc-MDP scans were reviewed. For a quantitative analysis, the region of interest on the frozen bone segment and a symmetric region of interest on the contralateral normal area were manually set. The radioactive tracer uptake ratio was calculated by dividing the count density of the frozen bone segment by that of the contralateral normal area in each image. An uptake ratio of 0.9 to 1.1 was defined as a normalization of tracer uptake. RESULTS Normalization of tracer uptake was achieved in 95% to 97% of the cases by 60 months postoperatively, and earlier in the middle zone and peripheral zone in the pedicle freezing group in comparison to the free freezing group (both P = 0.03). Fracture and nonunion was associated with a low uptake ratio, whereas infection was associated with a high uptake ratio before the occurrence of the event. CONCLUSIONS The calculation of the uptake ratio using 99m Tc-MDP scans was an objective and accurate evaluation method. The period to normalization of tracer uptake in the pedicle frozen bone was significantly earlier than that in the free frozen bone. The postoperative complications can be also predicted.

Abstract
Abstract
Background
Balloon pulmonary angioplasty (BPA) would be promising treatment option for non-operable chronic thromboembolic pulmonary hypertension (CTEPH). However, BPA for CTEPH with Chronic obstructive pulmonary disease (COPD) might exacerbate ventilation perfusion mismatch. The aim is to evaluate the efficacy and safety of BPA for CTEPH with moderate or severe COPD.
Method
Data from 149 CTEPH patients were collected retrospectively who underwent BPA from March 2011 to June 2021. Patients were divided according to the comorbidity of COPD: a COPD group (defined as forced expiratory volume in one second (FEV1.0) / forced vital capacity (FVC)<70% and FEV1.0<80% predicted [n=32]) or a non-COPD group [n=101]. Mild COPD patients (n=16) were excluded. Hemodynamics and respiratory parameters were compared.
Results
Hemodynamics improved similarly in both group (percent decrease of pulmonary vascular resistance; −61.1±12.3% in a COPD group, −65.8±11.1% in a non-COPD group, p=N.S). Patients in a COPD group showed improved respiratory function and oxygenation with FEV1.0% from 61.8±7.0% to 66.5±10.2% (p=0.02), and partial pressure of arterial oxygen from 60.9±10.6mmHg to 69.3±13.6mmHg (p<0.01). Higher vital capacity (r2=0.123, p=0.024), higher diffusing capacity for lung carbon monoxide (r2=0.308, p=0.028) at baseline were correlated with larger improvement of oxygenation after BPA in multivariate linear analyses. Lung injury per session was 1.6% in a COPD group.
Conclusion
The efficacy and safety of BPA for non-operable CTEPH with COPD were equivalent to those of patients without COPD. Oxygenation and FEV1.0% also improved in COPD patients. BPA might be considered even though patients comorbid COPD.

Abstract
Recently, the prognosis of metastatic renal cell carcinoma (mRCC) has improved owing to the development of immunotherapy using immune checkpoint inhibitors (ICIs). However, there have been few studies on the therapeutic effect of ICIs in bone metastases from renal cell carcinoma (RCC). We report a case in which pulmonary and humeral metastases from RCC were significantly ameliorated using ICIs, while surgery for a pathological fracture of the humerus significantly improved the patient’s quality of life (QoL). A 70-year-old man who underwent a left nephrectomy for RCC developed multiple pulmonary metastases and humeral metastasis with a pathological fracture one year after surgery, and combined treatment with nivolumab and ipilimumab was initiated. After four courses of ICI treatment, multiple pulmonary metastases had almost disappeared, and the tumor at the fracture site had shrunk remarkably. However, the shoulder joint function had decreased due to the fracture, worsening his QoL. Therefore, he underwent surgery and returned to normal daily life one month after. Postoperative histopathological examination of bone and soft tissue at the fracture site revealed no malignancy. To our knowledge, this is the first case report of complete remission of bone metastasis of RCC based on histopathological examination with ICI treatment.

Abstract
Objectives The national database for long-term care insurance (LTCI) of Japan (Kaigo DB) enables researchers to access comprehensive data from its LTCI registry, eligibility assessment records, claims for service usage, and information about service providers. However, studies regarding the death or mortality of beneficiaries cannot be conducted because Kaigo DB does not contain death records, and researchers are not allowed to link Kaigo DB to other databases, such as national death records. Therefore, we aimed to assess the validity of using an insurer's disqualification from an LTCI beneficiary as a proxy of death.Methods We used 510,751,798 monthly beneficiary records between April 2007 and March 2017 from the LTCI registry, while excluding data for ineligible persons for LTCI benefit or those younger than 65 years. We identified insurer cases disqualified from LTCI beneficiaries and linked them to national death records using deterministic linkage methods by dates of birth and death, sex, and residence. We considered the cases as positive if they were disqualified and their record was linked to a death. We used sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) as validity indices.Results We identified 5,986,991 (1.17%) disqualified and 5,295,961 death cases. Sensitivity, specificity, PPV, and NPV of disqualification for death were 100%, 99.86%, 88.46%, and 100%, respectively. After stratification, PPV of disqualification was between 85% and 88% before 2012, 91% after 2012, 91.9% in men, and 85.9% in women. PPV increased with age (65-69 years: 80.6%, 70-74 years: 86.7%, 75-79 years: 86.4%, 80-84 years: 86.7%, 85-89 years: 88.0%, 90-94 years: 90.6%, and 95+ years: 93.4%) and level of care needed (support level: 72.2%, care level (CL) 1: 79.7%, CL2: 85.9%, CL3: 89.3%, CL4: 92.3%, and CL5: 94.0%).Conclusions Disqualification from the LTCI registry is an inappropriate measure to estimate mortality accurately because it has a 10% false-positive rate. However, it appears sufficiently valid to use disqualification as a proxy outcome of death, although the main effect or confounding of a possible predictor of death could be slightly underestimated.

Abstract
To provide quantitative feedback on surgical progress to ophthalmologists practicing inner limiting membrane (ILM) peeling, we developed an artificial eye module comprising a quartz crystal resonator (QCR) force sensor and a strain body that serves as a uniform force transmitter beneath a retinal model. Although a sufficiently large initial force must be loaded onto the QCR force sensor assembly to achieve stable contact with the strain body, the highly sensitive and wide dynamic-range property of this sensor enables the eye module to detect the slight forceps contact force. A parallel-plate strain body is used to achieve a uniform force sensitivity over the 4-mm-diameter ILM peeling region. Combining these two components allowed for a measurable force range of 0.22 mN to 29.6 N with a sensitivity error within -11.3 to 4.2% over the ILM peeling area. Using this eye module, we measured the applied force during a simulation involving artificial ILM peeling by an untrained individual and compensated for the long-term drift of the obtained force data using a newly developed algorithm. The compensated force data clearly captured the characteristics of several types of motion sequences observed from video recordings of the eye bottom using an ophthalmological microscope. As a result, we succeeded in extracting feature values that can be potentially related to trainee skill level, such as the mean and standard deviation of the pushing and peeling forces, corresponding, in the case of an untrained operator, to 122.6 ± 95.2 and 20.4 ± 13.2 mN, respectively.

Abstract
BackgroundIn immunoglobulin G4-related kidney disease (IgG4-RKD), persistent renal insufficiency may be observed despite the good initial response to glucocorticoids[1, 2]. However, its long-term prognosis in relation to renal function as well as malignancy and mortality has not been well clarified.ObjectivesTo clarify the long-term renal prognosis, complications of malignancy, mortality, and factors related to those outcomes in IgG4-RKD.MethodsWe retrospectively reviewed the medical records of patients with IgG4-RKD diagnosed by the expert members of the IgG4-RKD working group in the Japanese Society of Nephrology. We investigated clinical, radiological, and histopathological features at baseline and course of renal function, complications of malignancy, and mortality during the long-term observation periods (median 71 months) in 75 patients. Using collected data, we calculated the crude incidence rates (IR) of chronic kidney disease (CKD) status, malignancy, and death. Cox regression analyses were performed to assess CKD-related factors. Additionally, we calculated the standardized incidence ratio (SIR) of malignancy and standardized mortality ratio (SMR) using national Japan statistics.ResultsFifty-nine patients were male, and 16 were female (median age 70 years). At diagnosis, their median eGFR was 45.1 mL/min/1.73m2 (interquartile range [IQR] 28.6-69.9). Seventy-two patients (96%) were treated with prednisolone at a median initial dose of 30 (IQR 30-39) mg/day, leading to a reasonable initial improvement of renal function. The IR of CKD was 30.2/100 person-years, and 66.7% (50/75) of the patients showed CKD at the last visit. Age- and sex-adjusted Cox regression analyses indicated that lower eGFR (per 10 mL/min/1.73m2, hazard ratio [HR] 0.70, 95% confidence interval [CI] 0.61-0.80), pre-existing hypertension (HR 2.39, 95% CI 1.32-4.34), and wider areas with inflammation (>50% vs. <10%, HR 2.55, 95% CI 1.07-6.08) or fibrosis (>50% vs. <5%, HR 2.84, 95% CI 1.18-6.85) in the biopsied renal specimens at treatment initiation had a significant impact on the time to CKD. Eight patients (10.7%) died during follow-up due to malignancy, severe infection, cerebral hemorrhage, or myocardial infarction. The crude mortality rate was 1.76/100 person-years, and a SMR calculated according to national Japan statistics was 0.97 (95% CI 0.42-1.90). On the other hand, 15 patients were diagnosed as having malignancies during follow-up. The IR of malignancy was 3.71/100 person-years, and the SIR of malignancy was 1.80 (95% CI 1.03-2.93).ConclusionThis study suggests that pre-treated renal insufficiency and extensive renal inflammatory and fibrotic lesions are related to CKD under glucocorticoid therapy in IgG4-RKD. Similarly with the whole IgG4-related disease, IgG4-RKD may have an increased incidence of malignancy but a mortality rate equivalent to the age- and sex-matched Japanese population.References[1]Saeki T et al.

Abstract
Purpose The coagulation activation leads to thrombotic complications such as venous thromboembolism (VTE) in patients with coronavirus disease‐2019 (COVID‐19). Prophylactic anticoagulation therapy has been recommended for hospitalized COVID‐19 patients in clinical guidelines. This retrospective cohort study aimed to examine the association between pre‐admission anticoagulation treatment and three outcomes: in‐hospital death, VTE, and major bleeding among hospitalized COVID‐19 patients in Japan. Methods Using a large‐scale claims database built by the Medical Data Vision Co. in Japan, we identified patients hospitalized for COVID‐19 who had outpatient prescription data at least once within 3 months before being hospitalized. Exposure was set as pre‐admission anticoagulation treatment (direct oral anticoagulant or vitamin K antagonist), and outcomes were in‐hospital death, VTE, and major bleeding. We conducted multivariable logistic regression analyses, adjusting for a single summarized score (a propensity score of receiving pre‐admission anticoagulation) for VTE and major bleeding, due to the small number of outcomes. Results Among the 2612 analytic patients, 179 (6.9%) had pre‐admission anticoagulation. Crude incidence proportions were 13.4% versus 8.5% for in‐hospital death, 0.56% versus 0.58% for VTE, and 2.2% versus 1.1% for major bleeding among patients with and without pre‐admission anticoagulation, respectively. Adjusted odds ratios (95% confidence intervals) were 1.25 (0.75–2.08) for in‐hospital death, 0.21 (0.02–1.97) for VTE, and 2.63 (0.80–8.65) for major bleeding. Several sensitivity analyses did not change the results. Conclusions We found no evidence that pre‐admission anticoagulation treatment was associated with in‐hospital death. However, a larger sample size may be needed to conclude its effect on VTE and major bleeding.

Abstract
BACKGROUND/AIM Systemic inflammation responses have been associated with cancer development, progression and metastasis. Little is known about the risk of metastasis based on inflammatory-based scores in patients with osteosarcoma. PATIENTS AND METHODS A total of 65 osteosarcoma patients without metastasis at presentation were enrolled in this retrospective study. All had been diagnosed histologically, and their laboratory data at the first visit were collected from medical records. The inflammation-based scores, tumor size, location, staging, pathological fracture, treatment methods, follow-up periods, and metastasis-free duration were evaluated. RESULTS A multivariate Cox regression analysis revealed that a high platelet-lymphocyte ratio (PLR) >116 [hazard ratio (HR)=3.8, 95% confidence interval =1.5-9.3; p<0.01], and neutrophil count (NC) ≤4,030/μl (HR=4.5, 95%CI=1.7-12.3; p<0.01), were independent risk factors significantly associated with metastasis of osteosarcoma patients. CONCLUSION The combination of a high PLR >116 and NC ≤4,030/μl before treatment was a useful inflammatory-based prognostic indicator for metastasis in patients with osteosarcoma.

Abstract
IMPORTANCE The provision of in-home and community end-of-life care has emerged as an important policy issue for aging populations around the world. Despite most patients expressing the wish to die at home (as opposed to in the hospital), substantial geographic variation persists in the prevalence of in-home death at the end of life. OBJECTIVE To assess the association of municipal characteristics with variation in the place of death among care-dependent older people in Japan. DESIGN, SETTING, AND PARTICIPANTS In this cross-sectional study using multilevel logistic regression, analyses were performed using national claims data under Japan's long-term care insurance system. The study population included long-term care insurance beneficiaries 65 years and older who died in 2015, excluding those who died from external causes, such as unintentional injuries. Data analyses were conducted from January 1 to April 31, 2021. EXPOSURES Predisposing, enabling, and need factors at the individual and municipal levels according to a behavioral model. MAIN OUTCOMES AND MEASURES The outcome was whether individuals died at home or not. RESULTS This cross-sectional study analyzed 544 836 decedents (median [IQR] age, 87 [81-91] years; 300 142 [55.1%] female). The proportion of in-home deaths was 10.3%. In the multilevel null model, 7.2% of the variance in the place of death was associated with municipal-level characteristics. Municipal characteristics were associated with more of the variance than were prefectural characteristics (2.7%). The largest proportional change (7.3%) in variance at the municipality level was observed when enabling factors (ie, medical and long-term care resources) were added to the model. Municipalities with a high proportion of in-home death were more likely to have a higher supply of clinics, physicians, and care workers providing in-home services per population, as well as a lower number of hospital beds and long-term care facility workers per population. CONCLUSIONS AND RELEVANCE In this cross-sectional study, municipal characteristics explained a substantial proportion of the geographic variance in in-home death in Japan. These results suggest that municipal policy makers need to ensure an adequate supply of clinics, physicians, and care workers providing in-home services to meet the preferences of care-dependent older people who wish to spend their final days at home.

Abstract
Background Japan has promoted end-of-life care at home and in long-term care facilities, and the total proportion of in-hospital deaths has decreased recently. However, the difference in trends of in-hospital deaths by the cause of death remains unclear. We investigated the variation in trends of in-hospital deaths among older adults with long-term care from 2007 to 2017, by cause of death and place of care. Methods Using the national long-term care insurance registry, long-term care claims data, and national death records, we identified people aged 65 years or older who died between 2007 and 2017 and used long-term care services in the month before death. Using a joinpoint regression model, we evaluated time trends of the proportion of in-hospital deaths by cause of death (cancer, heart diseases, cerebrovascular diseases, pneumonia, and senility) and place of care (home, long-term care health facility, or long-term care welfare facility). Results Of the 3,261,839 participants, the mean age was 87.0 ± 8.0 years, and 59.2% were female. Overall, the proportion of in-hospital deaths decreased from 66.2% in 2007 to 55.3% in 2017. By cause of death, the proportion of in-hospital deaths remained the highest for pneumonia (81.6% in 2007 and 77.2% in 2017) and lowest for senility (25.5% in 2007 and 20.0% in 2017) in all types of places of care. The joinpoint regression analysis showed the steepest decline among those who died of senility, especially among long-term care health facility residents. Conclusions The findings of this nationwide study suggest that there was a decreasing trend of in-hospital deaths among older adults, although the speed of decline and absolute values varied widely depending on the cause of death and place of care.

Abstract
Abstract
Background
We aimed to investigate the nationwide epidemiology of food choking deaths in Japan.
Methods
Using Japan Vital Statistics death data (2006-2016), we identified food choking deaths based on the 10th revision of the International Statistical Classification of Diseases code W79 (Inhalation and ingestion of food causing obstruction of respiratory tract). The demographics of people with food choking deaths; temporal trend of food choking deaths by the year (overall and by age group) and the day of year; and prefecture variations, were reported.
Results
52,366 people experienced food choking deaths (median age, 82 years, 53% were men, and 57% occurred at home). The highest number of food choking deaths occurred in January 1, 2, and 3, in that order; and lowest in June. Despite a constant total number of cases at around 4000 yearly, the incidence proportion declined from 16.2 to 12.1 per 100,000 population from 2006 to 2016 among people aged 75-84 years. The proportion peaked at 53.5 (2008) and decreased to 43.6 (2016) among people aged ≥85 years. Prefecture variations occurred in the number of food choking deaths, highest in Niigata and lowest in Kyoto.
Conclusions
The results suggest targets (by age group, region, and day of the year) for the prevention of food choking deaths. Time trends and regional variations may be related to the consumption of Japanese rice cake (mochi), known as a major cause of food suffocation in Japan.
Key messages
The number of food choking deaths in Japan was highest on New Year’s Day.

Abstract
Age affects the clinical outcomes of cancer treatment, including those for bone sarcoma. Successful reconstruction using frozen autograft after excision of bone sarcoma has been reported; however, little is known about the clinical outcomes of frozen autograft reconstruction according to age. The purpose was to evaluate the clinical outcomes of the frozen autograft reconstruction focusing on skeletally mature adolescents and young adults (AYAs) that was 15 to 39 years of age. A total of 37 AYA patients with primary bone sarcoma on the appendicular skeleton were enrolled in this study. The mean follow-up period was 89 months. The graft survival (GS), overall survival (OS), recurrence-free survival (RFS), complications and the function were retrospectively evaluated using medical records. The 10-year GS, OS, and RFS rates were 76%, 84%, and 79%, respectively. Bone union was achieved with a rate of 94% within 1 year after surgery, and nonunion (n = 1) and fracture (n = 2) were infrequently observed. Graft removal was performed in 7 cases, and the most common reason for the removal was infection (n = 5). The Musculoskeletal Tumor Society score was excellent in 23 cases of the available 29 cases. Frozen autograft reconstruction for AYAs showed excellent clinical outcomes, although the long-term follow-up is required.

Abstract
BACKGROUND Synovial sarcoma is an aggressive but chemosensitive soft-tissue tumor. We retrospectively analyzed the efficacy of perioperative chemotherapy for synovial sarcoma with data from the nationwide database, Bone and Soft Tissue Tumor Registry in Japan. METHODS This study included 316 patients diagnosed with synovial sarcoma between 2006 and 2012. Oncologic outcomes were analyzed using a Cox-hazard regression model. Moreover, the effects of perioperative chemotherapy on outcomes were evaluated using a matched-pair analysis. The oncologic outcomes of patients who did or did not receive chemotherapy were compared (cx + and cx-). RESULTS Multivariate analysis revealed significant correlations of age (over 40, hazard ratio [HR] = 0.61, p = 0.043), margin status (marginal resection, HR = 0.18, p < 0.001 and intralesional resection, HR = 0.30, p = 0.013 versus wide resection) with overall survival; surgical margin type (marginal resection, HR = 0.14, p = 0.001 and intralesional resection, HR = 0.09, p = 0.035 versus wide resection) with local recurrence; and postoperative local recurrence (HR = 0.30, p = 0.027) and surgical margin (marginal resection, HR = 0.31, p = 0.023 versus wide resection) with distant relapse-free survival. Before propensity score matching, perioperative chemotherapy was mainly administered for young patients and patients with deeper tumor locations, larger tumors, more advanced-stage disease, and trunk location. The 3-year overall survival, local control, and distant relapse-free survival rates were 79.8%/89.3% (HR = 0.64, p = 0.114), 89.6%/93.0% (HR = 0.37, p = 0.171) and 71.4%/84.5% (HR = 0.60, p = 0.089) in the cx+/cx- groups, respectively. After propensity score matching, 152 patients were selected such that the patient demographics were nearly identical in both groups. The 3-year overall survival, local control, and distant relapse-free survival rates were 71.5%/86.0% (HR = 0.48, p = 0.055), 92.5%/93.3% (HR = 0.51, p = 0.436) and 68.4%/83.9% (HR = 0.47, p = 0.046) in the cx+/cx- groups, respectively. CONCLUSION This large-sample study indicated that the margin status and postoperative disease control were associated directly or indirectly with improved oncologic outcomes. However, the efficacy of perioperative chemotherapy for survival outcomes in synovial sarcoma patients was not proven in this Japanese database analysis.

Abstract
The abundance of courses available in a university often overwhelms students as they must select courses that are relevant to their academic interests and satisfy their requirements. A large number of existing studies in course recommendation systems focus on the accuracy of prediction to show students the most relevant courses with little consideration on interactivity and user perception. However, recent work has highlighted the importance of user-perceived aspects of recommendation systems, such as transparency, controllability, and user satisfaction. This paper introduces CourseQ, an interactive course recommendation system that allows students to explore courses by using a novel visual interface so as to improve transparency and user satisfaction of course recommendations. We describe the design concepts, interactions, and algorithm of the proposed system. A within-subject user study (N=32) was conducted to evaluate our system compared to a baseline interface without the proposed interactive visualization. The evaluation results show that our system improves many user-centric metrics including user acceptance and understanding of the recommendation results. Furthermore, our analysis of user interaction behaviors in the system indicates that CourseQ could help different users with their course-seeking tasks. Our results and discussions highlight the impact of visual and interactive features in course recommendation systems and inform the design of future recommendation systems for higher education.

Abstract
BACKGROUND/AIM The delayed initiation of treatment is not associated with good clinical outcomes in patients with malignancies. However, few previous studies have examined prognostic factors, including the delayed initiation of treatment, in malignant bone tumors. PATIENTS AND METHODS One hundred and one patients with malignant bone tumors were enrolled. Univariate and multivariate analyses were performed to identify factors predicting metastasis, including factors that delay the initiation of treatment. RESULTS The multivariate analysis revealed that high-grade bone malignancy (p<0.01), a >30-day delay in referral to a specialized hospital by a general practitioner (p=0.03), and large tumor size (>77 mm) (p=0.04), were independently associated with metastasis of malignant bone tumors. CONCLUSION When general practitioners notice a patient with a >77 mm bone tumor, early referral to a specialized hospital within one month might be essential for preventing metastasis.

Abstract
AIM The study assessed the association between boosting the workforce supply by types of long-term care services and in-home deaths among older people at the municipality level. METHODS A fixed-effect panel data analysis was conducted using administrative data for every 3 years from 2008 to 2014. The outcome was the proportion of home deaths, excluding those due to external factors, such as suicide or accident. The explanatory variables were the full-time equivalent numbers of care workers engaged in in-home services, day services, short-stay services, and long-term care facilities per 1000 population aged 65 years and older. Ordinary least squares estimation was conducted, with standard errors corrected for clustering at the prefecture level, adjusting the covariates. RESULTS Analysis included 1706 municipalities. One care worker increase providing day services per 1000 population aged 65 years and older was associated with a 0.09% increase in the proportion of deaths at home (95% CI: 0.008-0.17). Although statistically non-significant, the number of care workers providing in-home services was positively associated with the proportion of home deaths, whereas the number of those providing short-stay services and providing long-term care facilities and nursing home services were inversely associated with home deaths. CONCLUSIONS Given the increased number of care-dependent older people who opt to stay at home until death, and their informal caregivers who have the burden and stress of care, the findings suggest that policymakers should ensure that the number of care workers for day services is sufficient for supporting care recipients and informal caregivers.

Abstract
Background:Clinical characteristics of nonradiographic axial spondyloarthritis (nr-ax-SpA) are highly variable across patients, and may potentially vary across patient populations, particularly due to differing distributions of human leukocyte antigens (HLA) and other genetic factors. The majority of nr-ax-SpA studies have been conducted in Europe, the United States, and small studies are reported from Asia [1].Objectives:To delineate clinical characteristics of patients with nr-ax-SpA in Asian countries in comparison to other areas of the world.Methods:Utilizing the ASAS-COMOSPA data, an international cross-sectional observational study of SpA patients, we analyzed information on demographics, disease characteristics, comorbidities, and risk factors. Patients were classified by region: Asia (China, Japan, Singapore, South Korea, and Taiwan), and non-Asian countries (Europe, Americas, and Africa); patient characteristics, including diagnosis and treatment, were compared.Results:Among 3984 SpA patients included in the study, 1094 were from centers in Asian countries, and 2890 from other regions. 112/780 (14.4%) of axial SpA patients in Asian countries were nr-ax-SpA, substantially less than in other countries (486/1997, 24.3%). Nr-ax-SpA patients in Asian countries compared to nr-ax-SpA in other countries were more likely male (75.9 vs 47.1%), have onset (22.8 vs 27.8 years) and diagnosis (27.2 vs 34.5 years) at younger age, and experience less diagnostic delay (1.88 vs 2.92 years) (Table 1). Nr-ax-SpA patients in Asian countries have higher prevalence of positive HLA-B27 (90.6% vs 61.9%) and fewer peripheral signs such as arthritis, enthesitis, or dactylitis (53.6% vs 66.3%) but have similar rate of extra-articular manifestations (psoriasis, IBD, or uveitis) and co-morbidities. Disease activity, functional impairment, and inflammation on MRI were less in nr-ax-SpA patients in Asian countries. NSAIDs response was higher and use of methotrexate and b-DMARDs were lower among nr-ax-SpA in Asian countries.Conclusion:Among axial SpA patients, substantially lower frequency of nr-ax-SpA was observed in Asian countries compared to other regions of the world. Nr-ax-SpA patients in Asian countries were predominantly male, and had younger disease onset with higher HLA-B27 positivity rate and less peripheral signs, and better response to NSAIDs. These results offer an opportunity to improve both early diagnosis and treatment of nr-ax-SpA patients in Asian countries.Table 1.Characteristics of nonradiographic axial SpA in Asia versus non-Asian regionsVariablesAsianon-Asian regionsp valueN112486Age at disease diagnosis, yrs27.2 [21.1, 39.6]34.5 [27.7, 41.7]<0.001Diagnostic delay, yrs1.88 [0.27, 5.56]2.92 [0.59, 9.58]0.011Male (%)85 (75.9)229 (47.1)<0.001Sacroiliitis on MRI among tested (%)49 (67.1)341 (82.2)0.005HLA B27 positivity among measured (%)96 (90.6)273 (61.9)<0.001Inflammatory Back Pain (%)107 (95.5)478 (98.4)0.076Arthritis, enthesitis, or dactylitis (%)60 (53.6)322 (66.3)0.016Psoriasis (%)12 (10.7)82 (16.9)0.142Uveitis (%)20 (17.9)81 (16.7)0.870Inflammatory bowel disease (%)5 (4.5)27 (5.6)0.817Elevated CRP (%)37 (33.0)213 (43.8)0.048Physician global assessment (0-10)2.0 [1.0, 5.0]2.0 [1.0, 4.0]0.741Patient global assessment (0-10)3.0 [1.0, 6.0]4.0 [2.0, 6.0]0.012ASDAS-CRP1.40 [0.95, 2.08]1.97 [1.21, 2.78]<0.001BASFI0.8 [0.05, 2.65]2.9 [0.8, 5.6]<0.001Good response to NSAIDs (%)80 (71.4)272 (56.0)0.004Methotrexate use (%)18 (16.1)134 (27.6)0.016Biological DMARDs use (%)27 (24.1)191 (39.3)0.004References:[1]López-Medina C, Ramiro S, van der Heijde D, et al.

Abstract
OBJECTIVES Despite the significant utilization of long-term care (LTC) services at the end of life, evidence on the trajectory of LTC expenditure in later life is scarce. This study aims to identify distinct trajectories of LTC expenditure in the last 5 years of life and to examine whether these trajectories differ according to cause of death. DESIGN A nationwide retrospective longitudinal cohort study based on linked data of National LTC Claims and the Japan's National Vital Statistic. SETTING AND PARTICIPANTS Participants comprised decedents aged 70 years or older and who died in 2017. METHODS We assessed 5 years of monthly LTC expenditure among participants and applied group-based trajectory model to identify distinct trajectories of LTC expenditure. Subsequently multinominal logistic regression analysis was performed to investigate how these trajectories vary according to cause of death. RESULTS Among 1,124,335 decedents, 4 distinct trajectories of LTC expenditure were identified: persistently low (58.5%), late increase (9.8%), progressive increase then late decrease (8.8%), and persistently high (22.9%). Approximately 80.7% of total LTC expenditure was spent by the persistently high group. After adjustment for age and sex; deaths due to age-related physical debility and dementia were associated with persistently high LTC expenditure. CONCLUSIONS AND IMPLICATIONS Ongoing discussions of LTC policy and reducing LTC expenditure may be more effective when emphasizing persistently high spenders. In addition, budget allocation for LTC at the end of life should be combined with data for health conditions.

Abstract
INTRODUCTION The web version of Fracture Risk Assessment (FRAX) tool is widely used in many countries to predict the 10-year probability of major osteoporotic fracture (MF) and hip fracture (HF) rate. However, other FRAX tools, calculator older version (first generation), calculator new version (second generation), and application of mobile software had also been used in Japan. PURPOSE The aim of this study is to investigate the consistency of results obtained from the four predicting tools for MF and HF rate in both male and female groups. METHODS The data were extracted from 2016 medical examination report of Japanese Ministry of Health of Labor and Welfare. The MF and HF rates were calculated from 40 to 90 years old under different risk factors using four FRAX tools while the consistency of predicting value was evaluated. RESULTS The predicted MF or HF rates were extremely similar among calculator new version, mobile software, and website version in each risk factors. On other hand, for calculator older version, the predicted MF or HF rates are a little higher than other versions. The significant difference is only present in patients aged 75 and above, and this exceeds the FRAX threshold older than 75 years old by Japanese Society for Bone and Mineral Research. CONCLUSIONS The application of four FRAX tools generated consistent results in predicting the 10-year probability of major osteoporotic fracture and HF for clinical practice, which provides an effective evidence for clinical application.

Abstract
Background Synchronous multicentric osteosarcoma (SMOS) is a rare disease characterized by simultaneous multicentricity of intraosseous osteosarcoma without visceral involvement. SMOS, including a skull lesion, which occurs relatively rarely, and reconstruction using a frozen autograft after the excision of a lesion of SMOS has been infrequently reported previously. Case presentation We report an 18-year-old girl with SMOS, with lesions located in the left distal femur, right proximal humerus, and left occipital bone. Her major complaint was pain and swelling around the left knee joint. Asymptomatic lesions of the humerus and skull bone were detected on a systemic bone scan. No visceral organ metastasis was observed. A biopsy of the distal femoral lesion revealed osteosarcoma. Based on the histological findings, multiple bone lesions, and absence of visceral lesion, the clinical diagnosis of SMOS was made. After five courses of neoadjuvant chemotherapy with a regimen of doxorubicin and cisplatin, reconstruction using a tumor prosthesis following wide excision of the left distal femur was performed, and total necrosis was histologically observed in the retracted specimen. Following three cycles of adjuvant chemotherapy, tumor excision and reconstruction with a frozen autograft treated with liquid nitrogen was conducted for both lesions of the humerus and skull, rather than tumor prosthesis or synthetics, in order to retain a normal shoulder function, and to obtain a good cosmetic and functional outcome after treatment of the skull lesion. Further adjuvant chemotherapy could not be administered after the completion of the surgical treatment for all lesions because the adverse events due to chemotherapy were observed. At over 5 years after the diagnosis, she remains clinically disease-free. Conclusions An early correct diagnosis, the proper management of chemotherapy, and surgical treatment for all lesions are essential for achieving a good clinical outcome, even in SMOS including a skull lesion. By performing reconstruction using a frozen autograft for a proximal humeral lesion and a skull lesion after confirming the good histological efficacy of neoadjuvant chemotherapy for the primary lesion, the excellent function of the shoulder joint and a good cosmetic outcome at the site of the skull lesion was acquired without complications or recurrence.

Abstract
Osteosarcoma is the most common primary malignant bone tumor, and its standard treatment is a combination of surgery and chemotherapy. A poor response to chemotherapy causes unfavorable oncological outcomes. We investigated the correlation between osteoclast differentiation in biopsy specimens and the efficacy of neoadjuvant chemotherapy in resected specimens. Forty-nine patients who underwent neoadjuvant chemotherapy and subsequent surgical treatment at our institution between 1999 and 2018 were enrolled. Using medical records, we investigated the age, sex, tumor size, location, subtype, staging, chemotherapy agents (doxorubicin, cisplatin, ifosfamide, and methotrexate), number of neoadjuvant chemotherapy courses, number of osteoclasts in biopsy specimens, and efficacy of neoadjuvant chemotherapy according to the Rosen and Huvos classification (Grade I-IV) in resected specimens. Univariate and multivariate analyses were performed to identify factors predictive of a good response in resected specimens after neoadjuvant chemotherapy. A good response (Grade III/IV) was detected in 25, while a poor response (Grade I/II) was detected in 24. According to the multivariate analysis, ≥ 46 years old (odds ratio [OR], 0.05; 95% confidence interval [CI], 0.01–0.45; p < 0.01) and ≥ 5 mature osteoclasts in a biopsy specimen (OR, 36.9; 95% CI, 6.03–225; p < 0.01) were significantly associated with the neoadjuvant chemotherapy efficacy. The accuracy for predicting a good response to chemotherapy based on ≥ 5 osteoclasts in a biopsy specimen in patients < 46 years old was 85%. The number of mature osteoclasts in biopsy specimens is a simple factor for predicting the efficacy of chemotherapy before treatment, although further studies will be required to determine the underlying mechanism.

Abstract
OBJECTIVE To examine the association between the severity of oral frailty (OF), which is one of the comprehensive oral functions evaluated, and dietary variety in community-dwelling older persons. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS A total of 769 community-dwelling older persons aged 65 and over. INTERVENTIONS We examined basic demographic information, functional status, cognitive status, depressive symptoms, medical history, and oral functions of the participants. MEASUREMENTS OF was defined by 1-2 and 3 or more of 6 items of oral function evaluation in the pre-oral frailty and oral frailty groups, respectively. Dietary variety was assessed using the dietary variety score (DVS). The participants were categorized into 3 groups for evaluation: those with a low score (0-2), medium score (3-5), and high score (≥6). Ordinal logistic regression analysis was performed to examine the association between OF and DVS. RESULTS The rate of OF in the participants was 21.6%, and its severity was significantly associated with DVS after adjusting for potential confounders (Pre-OF; adjusted odds ratio [OR] = 1.687, 95% confidence interval [CI] = 1.219-2.335, OF; adjusted OR = 2.857, 95% CI = 1.489-5.484). CONCLUSION The severity of OF was significantly associated with DVS in community-dwelling older persons. This suggests that DVS may be useful in understanding the effects of OF on the nutritional status. Further longitudinal studies are needed to elucidate the association between OF and DVS.

Abstract
Background: There is limited evidence regarding associations between fruit and vegetable consumption and incident frailty risk among older people. Objectives: The objective of this study was to conduct a systematic review and meta-analysis regarding the association between fruit and vegetable consumption and incident frailty risk among older adults. Methods: A systematic search of the literature was conducted according to the PRISMA guidelines using PubMed in January 2021 for studies that prospectively examined risk of incident frailty in relation to fruit and vegetable consumption in older adults aged 60 and older. Methodological quality and heterogeneity were assessed. Odds ratios (OR) were pooled using random-effects or fixed-effects meta-analysis, depending on the presence of heterogeneity. Results: Among three studies included in this review, data of four cohorts were provided by two studies and used in meta-analysis. The highest fruit and vegetable consumption was significantly associated with lower risk of incident frailty compared with the lowest consumption (pooled OR=0.38, 95%CI=0.24-0.59, p=<0.001). Conclusions: This study provided the pooled evidence that high fruit and vegetable consumption may be beneficial for preventing the development of frailty in older adults. Increasing fruit and vegetable consumption can be a relevant strategy to prevent frailty.

Abstract
BACKGROUND/AIM The delayed initiation of treatment is associated with poor clinical outcomes in patients with malignancies. However, few previous studies have investigated prognostic factors, including the delayed initiation of treatment, in soft-tissue sarcoma. PATIENTS AND METHODS One hundred and fifty-three patients with soft-tissue sarcoma were enrolled. Univariate and multivariate analyses were performed to identify factors predicting metastasis, including factors that delay the initiation of treatment. RESULTS The multivariate analysis revealed that high histological grade (p<0.01), tumor located in the trunk (p=0.04), >5-month delay from symptom initiation to consultation of general practitioner (p=0.02), and >29-day delay in referral to a specialized hospital by general practitioners (p=0.03) were independently associated with metastasis of soft tissue sarcoma. CONCLUSION Early consultation of a general practitioner and early referral to a specialized hospital might be essential for preventing metastasis of soft-tissue sarcoma.

Abstract
BACKGROUND Atypical fractures may occur due to the combined effect of severely suppressed bone turnover (SSBT) caused by long-term bisphosphonate treatment and chronic repetitive bone microdamage. Atypical fracture of the ulna due to SSBT is a rare entity; there is no standardized treatment strategy for this condition. We successfully treated a patient with atypical fracture of the ulna. Herein, we present this patient, review the relevant literature, and discuss the treatment strategy. CASE PRESENTATION An 84-year-old woman presented with atypical fracture of the left ulnar shaft due to SSBT. She had a history of bisphosphonate therapy (ibandronate and alendronate) since more than 10 years; her bone turnover was severely suppressed. We performed open reduction and internal fixation (ORIF) using dual plate with some additional treatments. These included drilling and decortication, use of autogenous bone graft, low-intensity pulsed ultrasound (LIPUS) treatment, and administration of teriparatide. Finally, bone union was observed at 11 months after surgery. CONCLUSIONS Based on the literature review and our experience with this case, ORIF alone may not be adequate to achieve bone union; drilling, decortication, and use of cancellus bone graft is important to achieve favorable outcomes. Administration of teriparatide and LIPUS may facilitate early bone union, although further studies are required to provide more definitive evidence. Furthermore, ORIF using dual plate may help avoid implant failure owing to the long time required for bone union.

Abstract
Background Pulmonary hypertrophic osteoarthropathy (PHO) is a rare paraneoplastic syndrome that mainly occurs in patients with lung cancer. Most symptoms occur symmetrically, and unilateral symptoms without clubbing are infrequent. This report presents the case of a rare atypical symptom that was highly suspected of being PHO. Case presentation A 77-year-old woman with swelling and severe pain in the left femur for 2 months was referred to our hospital. Radiography revealed a remarkably osteogenic thickening and sclerotic lesion in her distal femur. Preliminary diagnoses of malignant bone tumor and hematological tumor were made based on laboratory test results, radiological examination, and clinical manifestation. A needle biopsy was performed, which ruled out the diagnosis of malignant bone tumors. A low-grade bone tumor was still suspected. After that, en bloc resection was performed, followed by replacement of the femur with a mega-prosthesis. Pathological analysis revealed no malignant tumor cells, and immunohistochemical staining for CDK4 and MDM2 yielded negative results. Meanwhile, pulmonary large cell carcinoma was identified on biopsy. Based on published studies, a diagnosis of atypical PHO was made according to clinical and imaging manifestations. Conclusions This is an infrequent case of PHO with unilateral symptoms in the left femur. When clinical manifestations and radiological findings are inconsistent with the pathological results, the possibility of benign lesions with malignant clinical manifestations or imaging features should be carefully considered.

Abstract
BACKGROUND/AIM We have previously developed a novel bone-targeting platinum compound, 3Pt, and showed that it has strong inhibitory activity against osteosarcoma cells and orthotopic cell-line xenograft mouse models. In the present report, we compared the efficacy of 3Pt to cisplatinum (CDDP) in a CDDP-resistant relapsed osteosarcoma patient-derived orthotopic xenograft (PDOX) mouse model. PATIENTS AND METHODS The tumor of a patient with osteosarcoma of the distal femur was treated with CDDP-based chemotherapy followed by surgery. The surgical specimen was used to establish a PDOX model. An osteosarcoma cell line was also established from the original patient tumor. Osteosarcoma cell viability was assessed with the WST-8 assay and the IC50 values were calculated. The PDOX models were randomized into three groups: untreated control, CDDP-treated group, and 3Pt-treated group. Tumor size and body weight were measured twice a week. RESULTS 3Pt had a strong concentration-dependent cytocidal effect in vitro. The IC50 value of 3Pt was significantly lower than that of CDDP. On day 14 of the treatment, 3Pt caused a significantly greater tumor growth inhibition compared to the untreated control and CDDP-treated mice. CONCLUSION 3Pt is a promising clinical candidate for the treatment of recalcitrant osteosarcoma.

Abstract
Background Intramedullary osteosclerosis (IMOS) is a rare condition without specific radiological findings except for the osteosclerotic lesion and is not associated with family history and infection, trauma, or systemic illness. Although the diagnosis of IMOS is confirmed after excluding other osteosclerotic lesions, IMOS is not well known because of its rarity and no specific feature. Therefore, these situations might result in delayed diagnosis. Hence, this case report aimed to investigate three cases of IMOS and discuss imaging findings and clinical outcomes. Case presentation All three cases were examined between 2015 and 2019. The location of osteosclerotic lesions were femoral diaphyses in the 60-year-old man (Case 1) and 41-year-old woman (Case 2) and tibial diaphysis in the 44-year-old woman (Case 3). All cases complained of severe pain and showed massive diaphyseal osteosclerotic lesions in plain radiograms and computed tomography (CT) scans. Cases 2 and 3 were examined using the triphasic bone scan, and a fusiform-shaped intense area of the tracer uptake on delayed bone image was detected in both cases without (Case 2) or slightly increased vascularity (Case 3) on the blood pool image, which was reported as a specific finding of IMOS. Open biopsy was performed in all cases, and histologic section showed trabecular bone sclerosis with hypocellular fibrous tissues, finally diagnosed as IMOS. The pain was sharply improved after biopsy and kept at the latest follow-up periods (34, 33, and 6 months in Cases 1, 2, and 3, respectively). Conclusions Massive sclerotic lesions with severe pain in the diaphyseal region of long bones should be considered as IMOS to avoid the delayed diagnosis, although other sclerotic bony lesions should be carefully excluded. Triphasic bone scan with a fusiform-shaped intense area of tracer uptake on delayed bone image and without or slightly increased vascularity on the blood pool image will help confirm IMOS. The role of open biopsy was to confirm the diagnosis of IMOS and to give the severe pain relief immediately in the three cases, although more cases and long-term follow-up are necessary.

Abstract
Abstract
Background
It has been reported that balloon pulmonary angioplasty (BPA) could dramatically improve hemodynamics in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, some patients have shown poor response in oxygenation and lung function even after BPA. The aim of our study was to evaluate the efficacy of BPA using clinical indicators and to investigate lung function and residual hypoxemia.
Method
Consecutive 103 patients who underwent BPA from September 2011 to August 2018 were enrolled. We evaluated hemodynamics with right heart catheterization, respiratory function test, arterial blood gas examination, and exercise capacity with 6 minute-walk-distance (6MWD).
Result
At the median 12-month follow-up after the final BPA session, following examination findings were significantly improved. Mean pulmonary artery pressure (39.0±8.2mmHg, 23.2±8.4mmHg, p<0.001), Pulmonary vascular resistance (782±378 dynes / sec / cm-5, 331±187 dynes / sec / cm-5, p<0.001), 6 MWD (310±94 m, 363±119 m, p<0.001), PaO2 (63.1±15.8 mmHg, 68.5±13.6 mmHg, p=0.044),%VC (88.5±17.1, 91±16.3, p=0.036). However, the following examination findings did not improve after BPA. Oxygen desaturation during 6MWD test (−11.9±6.3, 12±7.9, p=0.65), %DLCO (64.2 17.1, 61.3 16.8, p=0.147).
Conclusion
BPA could dramatically improve hemodynamics and exercise tolerance. However, arterial oxygenation was not normalized after BPA. Moreover, oxygen desaturation in exercise, and %DLCO were almost unchanged. These observations might suggest the remaining arteriopathy in capillary level of pulmonary artery, but further research is needed.

Abstract
Background
This study evaluated whether caffeine abstention is required before fractional flow reserve (FFR) measurement by intravenous adenosine triphosphate (ATP) administration in Japanese patients.
Methods and results
This study was a subanalysis of a previously published study and a total of 208 intermediate lesions that underwent FFR measurements were enrolled for this analysis. Hyperemia was induced by continuous intravenous ATP infusion at 150μg/kg/min (IVATP150) and 210μg/kg/min (IVATP210), and by intracoronary administration of nicorandil 2mg (ICNIC2mg) as a reference standard. The degree of change in the FFR value both after IVATP150 and after IVATP210, as compared with the FFR value after ICNIC2mg was similar between the caffeine and non-caffeine groups (−0.04±0.05 vs. −0.04±0.07, and 0.00±0.02 vs. 0.01±0.02, respectively). In patients who consumed caffeine before the FFR measurement, the degree of FFR change was independent of the time interval (<12 hours, 12–24 hours, and 24–48 hours) between caffeine intake and catheterization both after IVATP150 and ICNIC2mg and after IVATP210 and ICNIC2mg.
Conclusion
When compared with the FFR value after ICNIC2mg, the degree of change in the FFR value both after IVATP150 and after IVATP210 remained similar regardless of caffeine intake. Strict caffeine abstention before intravenous ATP-induced FFR measurement may not be required in clinical practice.

Abstract
Abstract
Background
It has been previously reported that poor subpleural perfusion (PSP) in dual-energy computed tomography (DE-CT) might suggest the microvasculopathy in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, it remains unclear whether pathological findings of microvasculopathy in CTEPH and pulmonary arterial hypertension (PAH) are equivalent. The aim is to evaluate the microvasculopathy in CTEPH and PAH by using clinical parameters and DE-CT.
Methods
We retrospectively reviewed PSP (defined as subpleural spaces either not or minimally perfused in all segments) of consecutive treatment-naïve 89 CTEPH patients and 20 PAH patients who underwent DECT from Feb. 2015 to Dec. 2019.
We also evaluated hemodynamic parameters and DE-CT parameters including quantitative evaluation of pulmonary blood volume (PBV) which was calculated as the average of entire lung iodine density.
Results
PSP was observed in 49.4% of patients in CTEPH group versus 5.0% in PAH group (p<0.01).
There were no significant differences in hemodynamics and lung PBV between CTEPH group and PAH group (mean pulmonary arterial pressure; 36.4±10.4mmHg vs 38.3±8.5mmHg p=0.464, pulmonary vascular resistance; 700±388dyne*sec/cm5 vs 805±440 dyne*sec/cm5 p=0.288, lung PBV; 24.9±6.4 Hounsfield Unit vs 22.0±6.6 Hounsfield Unit p=0.06, respectively), however diffusing capacity for carbon monoxide (%DLCO/VA) was significantly lower (69.5±16.8% vs 45.7±23.7% p<0.01) in PAH group.
Conclusion
PSP in DE-CT, which was observed more frequently in patients with CTEPH, might suggest the different mechanism of microvasculopathy from PAH in patients with CTEPH. Microvasculopathy in CTEPH would be diffuse very distal thrombosis. DE-CT is effective modality to detect microvasculopathy of diffuse distal thrombosis in patients with CTEPH.

Abstract
Abstract
Background
Metabolic syndrome is a cluster of conditions including obesity, insulin resistance, hypertension, and abnormal cholesterol, which increases the cardiovascular risk. Metabolic syndrome or obesity has been reported to provide systemic inflammation and oxidative stress. Increased epicardial fat volume is a manifestation of obesity or metabolic syndrome. Those systemic and local conditions related to obesity or metabolic syndrome have been linking to the risk of atrial fibrillation (AF). The underlying mechanisms of obesity linking epicardial fat to AF progression have not been fully examined.
Purpose
To investigate the impact of obesity linked to epicardial fat on electrophysiologic and anatomical AF substrates.
Methods
Twenty dogs aged 3 years were divided into four groups (n=5 per each): normal diet for over 20 weeks (control group [median body weight: 12.0 kg]), rapid atrial pacing (RAP) for last 4–15 (median 8) weeks during a normal diet for the same period (RAP group [10.5 kg]), high-fat diet (HFD) maintained for over 20 weeks without RAP (MetS group [16.0 kg]), and RAP for last 4–12 (median 6) weeks during HFD maintained for 24 weeks (MetS-RAP group [17.0 kg]), respectively. Activation/voltage maps of the atria during sinus rhythm were created with Ensite NavX mapping system. The effective refractory period (ERP) at 5 left atrial (LA) and pulmonary vein (PV) sites (LA appendage [LAA], LA body, right and left superior PVs, and inferior PV), and AF inducibility by burst LAA pacing were determined. At study completion, hearts were excised for histopathological and gene expression analyses.
Results
The LA pressure was more significantly increased in MetS than the MetS-RAP, RAP, and control groups (22.5 [17–28.8] mmHg vs. 14.0 [10.5–16.3] mmHg, 10.5 [7.4–17.2] mmHg and 10.7 [9.6–13.5] mmHg, respectively, P<0.05). The LA/PV ERP at a basic cycle length of 400 ms was shorter in the MetS-RAP and RAP than MetS and control groups (118±39 ms and 122±44 ms vs. 136±18 ms and 155±39 ms, respectively, P<0.05). Short duration AF was more induced in the MetS and MetS-RAP than RAP and control groups (3 [0–5.5] sec and 2 [0.5–3.5] sec vs. 0 [0–4.5] sec and 0 [0–0] sec, P<0.05). Histological examinations showed the fatty infiltration extending from epicardial fat increased more in the Mets and Mets-RAP than RAP and control groups (Figure). The Fibronectin 1 and collagen I/III mRNA levels increased more in the MetS-RAP and AF than MetS and control groups.
Conclusions
AF vulnerability was associated with increased LA pressures and fibrofatty infiltration from epicardial fat in the MetS group, and with fibrofatty infiltration from epicardial fat with subtle fibrosis in the MetS-RAP group. This suggested that fibrofatty infiltration and epicardial fat plays an important role in AF pathogenesis in obese patients.
