Abstract
PURPOSE/OBJECTIVE(S) Several studies have shown that liver function can be evaluated after hepatic stereotactic body radiation therapy (SBRT) using galactosyl human serum albumin (GSA) liver scintigraphy and Gd-EOB-DTPA-enhanced magnetic resonance imaging (MRI). However, there are no reports investigating the relationship (including Chile-Pugh classification) between imaging and blood tests. Therefore, we investigated the changes that occur in the liver between before and after SBRT by combining imaging (GSA, computed tomography (CT), and MRI) with blood tests that assess total liver function (albumin-bilirubin (ALBI) grade, ICG-R15). We decided to find a method that could assess liver reserve capacity locally and globally MATERIALS/METHODS: Of the 23 patients who underwent hepatic SBRT, 12 patients underwent GSA, MRI, and ICG-R15 testing before treatment, 1 month after treatment, and 3 months after treatment. All patients underwent imaging studies and blood tests at the beginning of treatment, 1 month after treatment, and 3 months after treatment ended. The evaluation items were as follows: 1) changes over time in Child-Pugh classification, ICG-R15, and ALBI values before and after SBRT; 2) changes over time in GSA count and ICG; and 3) selection of the optimal sequence for recognizing radiation hepatitis on MRI. RESULTS The ICG values were 14.4 before RT, 17.1 after 1 month, and 17.6 after 3 months. ICG worsened after 1 month of treatment, but was similar after 3 months. ALBI values were -2.61 before RT, -2.67 after 1 month, and -2.71 after 3 months. ALBl worsened slightly over time. CONCLUSION Regarding the ICG-R15, there was an average worsening of 2.8 after 1 month of treatment compared with before SBRT, but only of 0.5 between 1 month and 3 months after SBRT. Therefore, evaluation using ICG-R15 after SBRT after 1 month alone may be sufficient.

Abstract
Squamous cell carcinoma antigen (SCC-Ag) and cytokeratin 19 fragment (CYFRA) are used to screen and monitor oral cancer patients. However, recent studies have reported that tumour markers become elevated as renal function decreases, regardless of tumour progression. A retrospective study was performed of 423 oral cancer patients who underwent blood testing for these tumour markers and other blood analytes during a 10-year period. The values of SCC-Ag and CYFRA increased significantly with decreasing renal function (P < 0.01), and the values were abnormal at a median 2.6 ng/ml for SCC-Ag and 4.7 ng/ml for CYFRA in the group with estimated glomerular filtration rate (eGFR) values of< 30 ml/min/1.73 m2. The factors that were related to the variation in tumour markers were albumin and creatinine. The cut-off values of eGFR were 59.7 ml/min/1.73 m2 for SCC-Ag and 63.6 ml/min/1.73 m2 for CYFRA, and the cut-off age when the tumour markers might rise due to the effect of renal function were 72 years for SCC-Ag and 73 years for CYFRA. In conclusion, decreased renal function should be taken into account when evaluating tumour markers in oral cancer. In addition, tumour markers are likely to be overestimated in patients over the age of 72-73 years.

Abstract
We present the first search for the pair production of dark particles X via K_{L}^{0}→XX with X decaying into two photons using the data collected by the KOTO experiment. No signal was observed in the mass range of 40-110 MeV/c^{2} and 210-240 MeV/c^{2}. This sets upper limits on the branching fractions as B(K_{L}^{0}→XX)<(1-4)×10^{-7} and B(K_{L}^{0}→XX)<(1-2)×10^{-6} at the 90% confidence level for the two mass regions, respectively.

Abstract
BACKGROUND In older people, frailty has been recognized as an important prognostic factor. However, only a few studies have focused on multidimensional frailty as a predictor of mortality and readmission among inpatients with pneumonia. OBJECTIVE The present study aimed to assess the association between preadmission frailty and clinical outcomes after the hospitalization of older patients with pneumonia. DESIGN Single-center, retrospective case-control study. SETTING Acute phase hospital at Kobe, Japan. PARTICIPANTS The present study included 654 consecutive older inpatients with pneumonia. MEASUREMENTS Frailty status before admission was assessed using total Kihon Checklist (KCL) score, which has been used as a self-administered questionnaire to assess comprehensive frailty, including physical, social, and cognitive status. The primary outcome was a composited 6-month mortality and readmission after discharge. RESULTS In total, 330 patients were analyzed (median age: 79 years, male: 70.4%, median total KCL score: 10 points), of which 68 were readmitted and 10 died within 6 months. After multivariate analysis, total KCL score was associated with a composited 6-month mortality and readmission (adjusted hazard ratio, 1.07; 95% confidence interval, 1.02-1.12; p = 0.006). The cutoff value for total KCL score determined by receiver operating characteristic curve analysis was 15 points (area under the curve = 0.610). The group with a total KCL score ≥ 15 points had significantly higher readmission or mortality rates than the groups with a total KCL score < 15 points (p < 0.001). CONCLUSIONS Preadmission frailty status in older patients with pneumonia was an independent risk factor for readmission and survival after hospitalization.

Abstract
BackgroundCrohn’s disease (CD) and ulcerative colitis (UC) are grouped as inflammatory bowel disease (IBD), and both are frequently found as extra-musculoskeletal manifestations in spondyloarthritis (SpA). Several studies have described the connection between SpA and IBD in both directions. Still until today, no studies have investigated possible differences in the musculoskeletal manifestations between the two main entities of inflammatory bowel disease: CD and UC.ObjectivesTo evaluate the clinical characteristics associated with the presence of CD or UC in patients with spondyloarthritis from the international cross-sectional ASAS-perSpA study.MethodsWe analyzed 3152 patients from the ASAS per-SpA cohort who had a diagnosis of axial SpA or peripheral SpA according to the treating rheumatologist. Patients with IBD - confirmed by endoscopy - were identified and stratified by CD or UC. Patients in which their IBD disease was not specified, were excluded. Demographics, clinical characteristics, treatments and patient-reported outcomes were compared between both subgroups.ResultsAmong the 146 patients diagnosed with IBD from the 3152 patients included in the analysis, 87 (59.6%) presented with CD (75 patients with axial SpA and 12 with peripheral SpA) and 39 (26.7%) with UC (34 patients with axial SpA and 5 with peripheral SpA) - Figure 1. A total of 20 (13.7%) patients with IBD were excluded, due to an inconclusive diagnosis of IBD. Patients with CD and UC had similar age (44.9 vs 44.0 years old) and sex distribution, although a slightly higher frequency of males was observed in CD than UC (63.2% vs 51.3%). The diagnostic delay for SpA was 7.0 years for CD and 8.1 years for UC. We did not find differences between both groups related to any musculoskeletal manifestations such as chronic back pain, uveitis, arthritis, enthesitis or dactylitis (Table 1). The only parameter showing a significant difference between CD and UC was the Bath Ankylosing Spondylitis Functional Index (BASFI) with a mean score of 3.3 vs 2.2 respectively (p=0.02) (Table 1). CD patients showed a higher tendency to be HLA-B27 positive (51.9% in CD vs. 39.4% in UC), but this did not reach statistical significance. No differences were observed regarding treatment patterns between both groups.Table 1.Demographics and clinical characteristics related to spondyloarthritis of patients with concomitant Crohn’s disease or ulcerative colitis (n=146).Crohn’s Disease N=87Ulcerative Colitis N=39PAge, mean (SD)44.9 (13.5)44.0 (13.0)0.68Sex, n/N (%) male55/87 (63.2)20/39 (51.3)0.21Smoker ever, n/N (%)36/87 (41.4)19/39 (48.7)0.44Diagnostic delay of SpA (years), mean (SD)7.0 (6.9)8.8 (8.1)0.38Psoriasis ever, n/N (%)9/87 (10.3)6/39 (15.4)0.47Uveitis ever, n/N (%)17/87 (19.5)11/39 (28.2)0.28Synovitis ever, n/N (%)42/87 (48.3)18/39 (46.2)0.83Enthesitis ever, n/N (%)26/87 (29.9)14/39 (35.9)0.50Dactylitis ever, n/N (%)3/87 (3.4)1/39 (2.6)0.79Axial involvement ever (according to the rheumatologist), n/N (%)79/87 (90.8)37/39 (94.9)0.44Sacroiliitis on X-ray, n/N (%)64/87 (73.6)26/39 (66.7)0.19HLA-B27 positive, n/N (%)28/54 (51.9)13/33 (39.4)0.26CRP mg/L, mean (SD)11.1 (33.8)15.3 (30.1)0.13ASDAS-CRP, mean (SD)2.4 (1.0)2.4 (1.1)0.84BASFI, mean (SD) 0-103.3 (2.6)2.2 (2.1)0.02csDMARDs ever, n/N (%)71/87 (81.6)35/39 (89.7)0.25bDMARDs ever, n/N (%)72/87 (82.8)33/39 (84.6)0.80ASDAS, Ankylosing Spondylitis Disease Activity Score; BASFI, Bath Ankylosing Spondylitis Functional Index; bDMARD, biological disease-modifying antirheumatic drugs; CRP, c-reactive protein; csDMARD, conventional synthetic disease-modifying antirheumatic drugs; SD, standard deviation; SpA, spondyloarthritis.ConclusionIn our ancillary analysis of the ASAS-perSpA study in patients with SpA and concomitant CD or UC, no differences in the clinical presentation or demographic characteristics between the two subgroups were observed, except for the BASFI.Disclosure of InterestsNone declared

Abstract
BACKGROUND: The presence of depressive symptoms in patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD) is an important research topic; however, the prevalence of depressive symptoms and the factors that influence their development are unclear.OBJECTIVE: To analyse the association between CES-D (Center for Epidemiological Studies Depression Scale) scores and clinical parameters such as age, disease duration, pulmonary function, imaging findings, blood data, physical functions, sleep disturbances, respiratory symptoms and health-related quality of life (HRQOL).METHODS: We conducted a cross-sectional retrospective study of 114 patients with NTM-PD at a single centre from March 2016 to January 2021 to evaluate the relationship between CES-D scores and clinical parameters.RESULTS: Participants had a median age of 64 years; 32.5% of them had depressive symptoms. Disease duration, albumin, C-reactive protein, pulmonary function, dyspnoea, exercise capacity, respiratory symptoms, cough-related HRQOL and sleep disturbances were associated with depressive symptoms. Binomial logistic regression analyses indicated that the CES-D score was significantly associated with cough-related HRQOL and sleep disturbances.CONCLUSION: A high percentage of NTM-PD patients in this study experienced depressive symptoms, and these patients had abnormalities of various clinical parameters. Cough-related HRQOL and sleep disturbance had a strong influence on the development of depressive symptoms.

Abstract
Circulating microRNAs (miRNAs) have been used as biomarkers for various diseases and physiological conditions in humans and mice; studies in domestic animals, particularly cattle, are limited. The importance of early pregnancy diagnosis (especially within the 21-d cow estrous cycle) in the livestock industry is extremely high. This study compared the circulating miRNAs in bred non-pregnant and pregnant Japanese Black cows, explored miRNAs as biomarkers for early pregnancy diagnosis, and established a measurement system that included selecting an appropriate reference miRNA and determining the effect of hemolysis on miRNA quantification in plasma. miRNA was extracted from the plasma of Japanese Black cows on day 21 after artificial insemination and subjected to a customized bovine oligonucleotide microarray for expression analysis. Differentially expressed miRNAs and reference miRNA candidates were selected and validated using reverse transcription-quantitative PCR (RT-qPCR). An appropriate endogenous reference miRNA for normalization was selected using NormFinder software. To evaluate the effect of hemolysis on miRNA quantification, hemolyzed samples were prepared using plasma from four cows in the estrous cycle and subjected to RT-qPCR. A total of 124 miRNAs were detected in bovine plasma by microarray analysis in bred non-pregnant and pregnant cows. The levels of five circulating miRNAs were significantly higher in pregnant cows than in bred non-pregnant cows, and 24 miRNAs were detected only in the pregnant group. NormFinder analysis and RT-qPCR validation showed that miR-2455 was an appropriate reference miRNA in the plasma of bred non-pregnant and pregnant Japanese Black cows, and miR-19b, miR-25, miR-29a, and miR-148a were significantly higher in the pregnant group. These four circulating miRNAs did not change during the estrous cycle and were less affected by hemolysis. In the current study, we found four miRNAs, miR-19b, miR-25, miR-29a, and miR-148a, which were present at high levels in the plasma of pregnant Japanese Black cows. Since these miRNAs are less affected by hemolysis, they may potentially be used as biomarkers for early pregnancy diagnosis in cattle.

Abstract
BACKGROUND PET (positron emission tomography) and CSF (cerebrospinal fluid) provide the "ATN" (Amyloid, Tau, Neurodegeneration) classification and play an essential role in early and differential diagnosis of Alzheimer's disease (AD). OBJECTIVE Biomarkers were evaluated in a Japanese multicenter study on cognitively unimpaired subjects (CU) and early (E) and late (L) mild cognitive impairment (MCI) patients. MEASUREMENTS A total of 38 (26 CU, 7 EMCI, 5 LMCI) subjects with the age of 65-84 were enrolled. Amyloid-PET and FDG-PET as well as structural MRI were acquired on all of them, with an additional tau-PET with 18F-flortaucipir on 15 and CSF measurement of Aβ1-42, P-tau, and T-tau on 18 subjects. Positivity of amyloid and tau was determined based on the positive result of either PET or CSF. RESULTS The amyloid positivity was 13/38, with discordance between PET and CSF in 6/18. Cortical tau deposition quantified with PET was significantly correlated with CSF P-tau, in spite of discordance in the binary positivity between visual PET interpretation and CSF P-tau in 5/8 (PET-/CSF+). Tau was positive in 7/9 amyloid positive and 8/16 amyloid negative subjects who underwent tau measurement, respectively. Overall, a large number of subjects presented quantitative measures and/or visual read that are close to the borderline of binary positivity, which caused, at least partly, the discordance between PET and CSF in amyloid and/or tau. Nine subjects presented either tau or FDG-PET positive while amyloid was negative, suggesting the possibility of non-AD disorders. CONCLUSION Positivity rate of amyloid and tau, together with their relationship, was consistent with previous reports. Multicenter study on subjects with very mild or no cognitive impairment may need refining the positivity criteria and cutoff level as well as strict quality control of the measurements.

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
BACKGROUND: Previous studies have shown a reduction in health-related quality of life (HRQoL) in patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD). However, the causes of this decline and the factors that contribute to it are unknown. This study was conducted to analyse the association between the St George´s Respiratory Questionnaire (SGRQ) and clinical parameters, including age, disease duration, body composition, pulmonary function, chest X-ray findings, blood data and physical function.METHODS: We performed a single-centre, cross-sectional, retrospective study of 101 patients with NTM-PD from December 2016 to October 2019. The relationship between the SGRQ scores and clinical parameters was evaluated.RESULTS: The median patient age was 67.0 years. Pulmonary function, radiological score, albumin levels, C-reactive protein levels and incremental shuttle walk test distance (ISWD) were significantly correlated with the total and component scores on the SGRQ. Multiple regression analysis showed that the SGRQ score was significantly associated with radiological score, pulmonary function and ISWD.CONCLUSION: This study was the first to assess the effect of clinical parameters on the SGRQ in patients with NTM-PD. HRQoL as determined using the SGRQ was associated with the radiological score, pulmonary function and ISWD in patients with NTM-PD.

Abstract
Abstract
Background
Atrial fibrosis is hallmark of structural remodeling in atrial fibrillation (AF), but the inflammatory mechanism remains unclear. The purpose of the present study was to identify the specific inflammatory biomarkers to atrial fibrosis evaluated by atrial low voltage (LV) in AF patients for clarification of the mechanism.
Methods
Forty inflammatory biomarkers were quantified in 16 consecutive AF patients measured left atrial low voltage during catheter ablation.
Results
Median %LV area was 17%. In Pearson's correlation analysis, interleukin (IL)-17A and interferon (IFN)-γ was the most significant positive and negative correlation with %LV (R=0.35 and 0.43, P<0.001). Furthermore, there was a significant correlation between IL-17A/IFN-γ ratio and %LV (R=0.65, P=0.007). The area under the receiver operator characteristics curve of IL-17A/IFN-γ ratio for significant LV (%LV >10% as a reference standard) was 0.88. IL-17A/IFN-γ ratio was significantly higher in patients with significant LV than those without (1.41 versus 0.97, P=0.01), Furthermore, the sensitivity, specificity, and accuracy for detecting significant LV were 60%, 100%, and 75.0% at the cutoff value of 1.3. The event free survival from recurrent atrial tachyarrhythmias was not significantly different between patients with and without IL-17A/IFN-γ ratio >1.3 (83.3% versus 80.0% at 1-year, P=0.81).
Conclusions
Among inflammatory biomarkers, IL-17A/IFN-γ ratio was a significant predictor for the severity of left atrial low voltage n AF patients. Further study is needed to reveal the association between IL-17A and IFN-γ for development of fibrosis in AF.

Abstract
Abstract
Background/Introduction
The medical systems of hospitals often differs between on weekends and weekdays. These differences could lead different clinical outcomes for patients with acute medical conditions that require complex treatment strategies. However, the effect of the time of diagnosis on clinical outcomes in patients with acute venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), is still controversial.
Purpose
We sought to evaluate the clinical characteristics and outcomes of patients with VTE comparing on weekends and weekdays in a large observational database of VTE in Japan.
Methods
The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic VTE objectively confirmed by imaging examination or by autopsy among 29 centers in Japan between January 2010 and August 2014. In the current analysis, diagnosis on weekends was defined as diagnosis during the period from 00:00 hours on Saturday to 24:00 on Sunday. All other times were defined as weekdays. We divided the entire cohort into 2 groups; diagnosis on weekends and diagnosis on weekdays groups, and we compared the clinical characteristics, management strategies and 30-day outcomes between the 2 groups.
Results
The current study population consisted of 337 patients diagnosed on weekends and 2690 patients diagnosed on weekdays. The median days from onset to diagnosis were shorter in the patients diagnosed on weekends than in those diagnosed on weekdays (2 days vs. 4 days, P<0.001). The patients diagnosed on weekends presented with PE more frequently (72% vs. 55%, P<0.001), and they showed more severe condition for PE with a higher simplified pulmonary embolism severity index score. The vast majority of PE patients were diagnosed by contrast-enhanced computed tomography in both groups (97% vs. 97%, P=0.67). The patients diagnosed on weekends more often received initial parenteral anticoagulation therapy and thrombolysis than those diagnosed on weekdays. The cumulative 30-day incidence of all-cause death was not significantly different between the 2 groups among PE patients (diagnosis on weekends: 6.2% vs. diagnosis on weekdays: 6.5%, P=0.87), as well as among DVT patients (0.0% vs. 1.5%, P=0.24) (Figure). After adjusting the confounders, the risk of diagnosis on weekends relative to diagnosis on weekdays for all-cause death among PE patients was still insignificant (adjusted HR: 0.76; 95% CI: 0.42–1.28). The most frequent cause of deaths was fatal PE in both groups among PE patients. The risks for recurrent VTE and major bleeding at 30 days were not significantly different between the 2 groups among PE patients nor DVT patients.
Conclusions
The VTE patients diagnosed on weekends presented with PE more frequently, and they showed more severe condition for PE, although the risks for short-term mortality were not significantly different between patients diagnosed on weekends and weekdays.

Abstract
A quantum two-level system with periodically modulated energy splitting could provide a minimal universal quantum heat machine. We present the experimental realization and the theoretical description of such a two-level system as an impurity electron spin in a silicon tunnel field-effect transistor. In the incoherent regime, the system can behave analogously to either an Otto heat engine or a refrigerator. The coherent regime could be described as a superposition of those two regimes, producing specific interference fringes in the observed source-drain current.

Abstract
OBJECTIVE The aim of the study is to investigate the apoptotic mechanism in salivary glands in the rat experimental periodontitis model. DESIGN A rat periodontitis model was prepared by using a ligature around the second upper molar. In the salivary (parotid and submandibular) glands and blood samples, putative apoptotic factors and pathway molecules were investigated in vivo and in vitro. RESULTS Four weeks of ligation (chronic periodontitis) demonstrated significant apoptotic atrophy of the salivary gland, but one week of ligation (initial periodontitis) did not. In the blood plasma, tumor necrosis factor-α (TNF-α) was increased in the periodontitis model, but interleukin-1β and -6 were not. TNF-α receptor type 1, which has an intracellular apoptotic pathway, was expressed in the salivary glands of rats. Western blot analysis of cultured rat primary salivary gland cells demonstrated that TNF-α induced cleavage of poly (ADP-ribose) polymerase (PARP) and caspase-3 in a dose-dependent manner, indicating apoptosis induction. Additionally, we found increment of circulating lymphocytes in the model. Expression of mRNA and immunoreactive cells for the B lymphocyte marker CD19 were increased in the salivary gland in the model. Western blotting showed that coculture with extracted B cells from the periodontitis model increased cleaved PARP in salivary gland cells. CONCLUSIONS Chronic periodontitis status leads to an increase in circulating TNF-α and B lymphocyte infiltration, resulting in apoptotic atrophy of the salivary gland as a periodontitis-induced systemic response.

Abstract
The chiral crystal is characterized by a lack of mirror symmetry and inversion center, resulting in the inequivalent right- and left-handed structures. In the noncentrosymmetric crystal structure, the spin and momentum of electrons are expected to be locked in the reciprocal space with the help of the spin-orbit interaction. To reveal the spin textures of chiral crystals, we investigate the spin and electronic structure in a p-type semiconductor, elemental tellurium, with the simplest chiral structure by using spin- and angle-resolved photoemission spectroscopy. Our data demonstrate that the highest valence band crossing the Fermi level has a spin component parallel to the electron momentum around the Brillouin zone corners. Significantly, we have also confirmed that the spin polarization is reversed in the crystal with the opposite chirality. The results indicate that the spin textures of the right- and left-handed chiral crystals are hedgehoglike, leading to unconventional magnetoelectric effects and nonreciprocal phenomena.

Abstract
INTRODUCTION Boron neutron capture therapy (BNCT) is form of tumor-cell selective particle irradiation. Although novel boron compounds have been developed, BPA (boronophenylalanine) and BSH (borocaptate sodium) are used in the clinical practice. The development of effective boron compounds is a major theme. We used Dodecaborate-containing BPA (AAL) which is combined the characteristics of both BPA and BSH. We have been conducting research on how the new compound for BNCT will affect rat brain tumor model. MATERIALS AND METHODS We evaluated the boron concentration of F98 glioma cells for BPA and AAL, and the biodistribution of these following BPA administrated intravenously (i.v.) or AAL administrated by convection-enhanced delivery (CED) in F98 glioma bearing rats. In BNCT study, the therapeutic effect was evaluated in terms of the survival time for all rats divided into six groups. RESULTS The uptake of boron showed almost the same value at all exposure times in high concentration. In biodistribution study, the AAL(CED) 6h after the termination group attained the highest boron concentrations of the tumor (59.9 ± 18.2 μg/g). In the BNCT study, the median survival time in the AAL(CED) group (31(29–35) days) was shorter than that in the BPA(i.v.) group(34(33–36) days). And the combination group of AAL(CED) and BPA(i.v.) gave the most significant prolongation of survival(38(36–40) days). DISCUSSION AAL(CED) and BPA(i.v.) combined group had a significant survival prolongation compared with the single-agent group. It is thought that AAL irradiated by thermal neutron had a cell-killing effect on cells in which BPA was not taken up. The combination uses of AAL (CED) provides additional BNCT effects. The mechanism by which AAL is incorporated has not been clarified, and further experiments including the influence on normal cells are in progress. CONCLUSION Dodecaborate-containing BPA (AAL) is a novel boron compound for BNCT that can be expected to prolong the survival time in combination with BPA.

Abstract
Abstract
Introduction
Left ventricular (LV) pressure-volume (P-V) loop area reflects stroke work (SW), but clinical use of this index is limited by the need of invasive pressure measurement. A noninvasive method to obtain LV pressure-strain loop was recently introduced to assess myocardial work (MW). The minimum LV diastolic pressure (mLVP) was reported to have a strong correlation with Tau and we reported that Tau was noninvasively evaluated by speckle tracking echocardiography (STE).
Purpose
We sought to evaluate the impact of preload change by leg lifts on LV SW noninvasively obtained by the novel method and to examine the utility to assess LV contractility by SW and end-diastolic (ED) volume relation (SW-VED).
Methods
Thirty six controls (age 71±10) and 30 patients with heart failure with reduced ejection fraction (EF) <50% (HF) (age 73±6) were enrolled. LV pressure in a cardiac cycle was estimated using systolic blood pressure (SBP), minimum diastolic pressure (mDP) and ED pressure (EDP) by utilizing the profile of an empiric, normalized reference curve. The mDP and EDP were estimated as (Tau − 33.7)/2.06 and as 12.3 − 10.1 x Log (left atrial active emptying function/minimum volume) as we reported. LVSW was obtained by P-V loop by the combination of these pressures and LV volume using 3-D STE.
Results
LVEF and longitudinal strain in HF before leg up by 3D-STE were lower compared to normal (LVEF; normal: 58±5 vs HF: 39±10*% and strain; −12±3 vs −8±3%*, *p<0.05 vs normal). LVEF was increased after leg up by 7±6% in normal and by 8±8% in HF associated with increased LVED volume (normal: 84±24 to 90±24 and HF: 124±36* to 136±42*ml). LV MW and SW in HF before leg up were lower compared to normal (MW: 1790±412 vs 1002±432*mmHg% and SW: 3946±1682 vs 3352±1026mmHgml). LV SW increased after leg up by 26±19% in normal and by 25±20% in HF. LV SW-VED in normal was greater than HF (241±151 vs 90±54*).
Conclusion
LV SW noninvasively obtained by P-V loop area was increased after leg up in both normal and HF but SW-VED in HF was smaller than normal, indicating reduced contractility in HF. This noninvasive method may be a new echocardiographic approach for quantification of LV SW and contractility.

Abstract
Abstract
Background
Left ventricular (LV) relaxation (eTau) and pulmonary capillary wedge pressure (ePCWP) were reported to be estimated by speckle tracking echocardiography (STE). LV camber stiffness (e-c stiffness) may be estimated with the use of 2 diastolic pressure-volume coordinates. The minimum diastolic pressure (mP) is reported to have a strong correlation with Tau.
Purpose
We sought to examine the impact of hypertension on LV diastolic function and LA properties and to elucidate the feature of hypertensive heart failure with preserved EF (HFpEF).
Methods
The e', E/e', Tau, PCWP, LVEDP, LV stiffness, LAV, LA emptying function (LAEF) and LA strain were examined in 53 controls (age 66±11), 136 hypertensive patients (HTN) with normal EF (69±11) and 39 HFpEF (77±14). ePCWP and estimated EDP (eEDP) was calculated as previously reported. Tau was calculated as isovolumic relaxation time/(ln 0.9 x systolic blood pressure − ln PCWP). Myocardial stiffness (e-m stiffness) was estimated as LVED stress/LV strain. LV c-stiffness was calculated as LV pressure change (from mP to EDP) obtained by catheterization divided by LV volume change. Estimated LV c-stiffness (e-c-stiffness) was noninvasively obtained using e-mP and e-EDP. The eTau, eEDP and e-mP by STE were validated by catheterization (n=126).
Results
The mP had a good correlation with Tau (r=0.70, p<0.01). The eTau, eEDP and e-mP by STE had a good correlation with those by catheterization (r=0.75, 0.63 and 0.70, p<0.01). Multivariate analysis revealed that ePCWP and LA strain were independent predictors of HFpEF.

Abstract
Abstract
Background/Introduction
Venous thromboembolism (VTE), including pulmonary embolism (PE) and deep vein thrombosis (DVT), has a long-term risk for recurrence, which can be prevented by anticoagulation therapy. The duration of anticoagulation therapy after VTE should be based on the balance between risks of recurrent VTE and bleeding. However, there is uncertainty about the impact of these events on subsequent mortality.
Purpose
We sought to evaluate the impact of recurrent VTE events and bleeding events on subsequent mortality in patients with VTE in a large retrospective observational database in Japan.
Methods
We evaluated the association of recurrent VTE and major bleeding with mortality among 3026 patients in the COMMAND VTE Registry. We estimated the risks of recurrent VTE events and major bleeding events for subsequent all-cause death with the multivariable Cox proportional hazard model. We incorporated the recurrent VTE events and major bleeding events during follow-up into the multivariable Cox model as time-updated covariates together with the clinically-relevant 16 risk-adjusting factors. We expressed the adjusted risks of each covariate as hazard ratios (HR) and their 95%confidence intervals (CI). Furthermore, to assess the risks of recurrent PE and recurrent DVT events for subsequent all-cause death respectively, we divided recurrent VTE events into recurrent PE (PE with or without DVT) and recurrent DVT (DVT only), and incorporated these events as well as major bleeding events into the multivariable Cox model as time-updated covariates.
Results
In the current study population, the mean age was 67 years, 61% were women, and mean body weight and body mass index were 57.9 kg and 23.2 kg/m2, respectively. During the median follow-up period of 1,218 days, 763 patients died, 225 patients developed recurrent VTE events, and 274 patients developed major bleeding events. The time-updated multivariable Cox proportional hazard model revealed that both the recurrent VTE events and the major bleeding events were strongly associated with subsequent mortality risk (recurrent VTE events: HR 3.24, 95% CI 2.57–4.08, P<0.001; major bleeding events: HR 3.53, 95% CI 2.88–4.31, P<0.001). Both the recurrent PE events and the recurrent DVT events were associated with subsequent mortality risk with the numerically greater magnitude of effect with the recurrent PE events than with the recurrent DVT events (recurrent PE events: HR 4.42, 95% CI 3.28–5.95, P<0.001; recurrent DVT events: HR 2.42, 95% CI 1.75–3.36, P<0.001).
Conclusions
In the real-world patients with VTE, both recurrent VTE events and major bleeding events were strongly associated with subsequent mortality risk with the comparable effect size. Recurrent PE and recurrent DVT events were also associated with increased risks for mortality, although the magnitude of the effect on mortality was numerically greater with the recurrent PE events than with the recurrent DVT events.

Abstract
Abstract
Background
We previously reported that pulmonary capillary wedge pressure (PCWP) was noninvasively evaluated by 2D speckle tracking echocardiography (STE). Recently, novel software was introduced to examine volume and function of left ventricular and left atrium (LA) by 3D-STE automatically.
Purpose
We sought to compare the PCWP estimated by conventional 2D-STE (2D-ePCWP) and by novel 3D-STE (3D-ePCWP), and validate those values by cardiac catheterization.
Methods
Echocardiography and catheterization were performed in 29 patients (age 72±2) (7 ischemic heart disease, 2 hypertensive heart disease, 5 dilated cardiomyopathy, 12 valvular heart disease and 3 primary pulmonary hypertension).The ePCWP (mmHg) is noninvasively obtained as 10.8 − 12.4 x Log (left atrial active emptying function/minimum volume) as we previously reported. Echocardiography was performed just before the catheterization and we analyzed the 2D and 3D data by novel off-line software. 3D data was automatically analyzed and the border settings were fixed at default (ES60, ED30) (Figure).
Results
2D-ePCWP and 3D-ePCWP had a good correlation with PCWP invasively obtained by catheterization (r=0.87 and 0.83, respectively, both p<0.001). There was an excellent correlation between 2D-ePCWP and 3D-ePCWP (r=0.94, p<0.001) and there was a good correlation between 2D-LA volume index and 3D- LA volume index (r=0.80, p<0.001). Bland-Altman analysis revealed a good agreement between 2D-ePCWP and 3D-ePCWP, and between 2D-ePCWP and 3D-ePCWP without fixed and proportional bias.
Conclusion
This study demonstrated that PCWP might be noninvasively assessed by not only 2D-STE but also 3D-STE with reasonable accuracy and 3D-STE might have utility and value in the routine clinical practice.

Abstract
Abstract
Background
Left ventricular (LV) diastolic function is mainly composed of LV relaxation and LV stiffness. We reported that pulmonary capillary wedge pressure (ePCWP) and LV relaxation assessed by Tau (eTau) are noninvasively evaluated by speckle tracking echocardiography (STE). The minimum LV diastolic pressure (mLVP) was reported to have a strong correlation with Tau. Therefore, LV chamber stiffness (c-stiffness) may be assessed with the use of two LV diastolic pressure-volume coordinates: the mLVP and volume and the end-diastolic pressure (EDP) and volume.
Purpose
We sought to noninvasively assess LV stiffness using STE and validate the value by cardiac catheterization.
Methods
Echocardiography and catheterization were performed in 124 patients (age 72±8) (70 angina pectoris, 20 prior myocardial infarction, 19 hypertensive heart disease, 11 congestive heart failure and 4 paroxysmal atrial fibrillation). The ePCWP (mmHg) is noninvasively obtained as 10.8 − 12.4 × Log (left atrial active emptying function/minimum volume) and the eTau (ms) is obtained as isovolumic relaxation time/(ln 0.9 × systolic blood pressure − ln ePCWP) as previously reported. The mLVP (e-mLVP) was estimate using Tau. The estimated EDP (e-EDP) was calculated as 12.3 − 10.1 × Log (left atrial active emptying function / minimum volume). LV c-stiffness (mmHg/ml) was calculated as LV pressure change (from mLVP to EDP) obtained by catheterization divided by LV volume change during diastole which equals to stroke volume by echocardiography. Estimated c-stiffness (e-c-stiffness) was noninvasively obtained using e-mLVP and e-EDP. Furthermore, LV myocardial stiffness (m-stiffness) was calculated by LVED stress / LV longitudinal strain by STE, where LV stress (kdynes/cm2) was calculated as 0.334 × pressure × dimension / [thickness (1 + thickness/dimension)]. The estimated m-stiffness (e-m-stiffness) was calculated using e-EDP.
Results
The eTau and e-EDP estimated by STE had a good correlation with Tau and EDP invasively obtained by catheterization (r=0.75 and 0.63, respectively, both p<0.001). There was a good correlation between Tau and mLVP (Tau = 2.06 mLVP + 33.7, r=0.70). The estimated LVED stress had good correlation with ED stress obtained by catheterization (r=0.77, p<0.001). The e-c-stiffness and e-m-stiffness had a good correlation with those obtained by catheterization (e-c-stiffness; 0.116±0.07 and c-stiffness; 0.115±0.06, r=0.603, e-m-stiffness; 0.81±0.41 and m-stiffness; 0.85±0.45, r=0.89, respectively). Bland-Altman analysis revealed a good agreement between e-c-stiffness and c-stiffness, and between e-m-stiffness and m-stiffness without fixed and proportional bias.
Conclusion
This study demonstrated that LV stiffness may be noninvasively assessed by STE with reasonable accuracy and may have utility and value in the routine clinical practice for the diagnosis and treatment in patients with diastolic dysfunction.

Abstract
Abstract
Background/Introduction
Pulmonary embolism (PE) is caused by blockage of pulmonary arteries by thrombus. The sources of thrombus are thought to be mostly veins in lower extremities, whereas deep vein thrombosis (DVT) in upper extremities rarely occurs spontaneously. Recent studies reported that DVT in upper extremities might have significant complications, and DVT in upper extremities could be increasing. However, there is a paucity of data on patients with DVT in upper extremities, leading to uncertainty in optimal treatment strategies including anticoagulation therapy.
Purpose
We sought to evaluate the clinical characteristics, management strategies, and long-term outcomes of patients with DVT in upper extremities in a large observational database in Japan.
Methods
The COMMAND VTE Registry is a multicenter registry enrolling 3027 consecutive patients with acute symptomatic venous thromboembolism (VTE) objectively confirmed by imaging examination or by autopsy among 29 centers in Japan between January 2010 and August 2014. The current study population consisted of 2498 patients with DVT in upper or lower extremities, after excluding 381 patients with PE only, 144 patients who had thrombus in locations other than upper or lower extremities, and 4 patients with DVT in both upper and lower extremities. The study patients were divided into 2 groups: patients with DVT in upper extremities and patients with DVT in lower extremities. We compared the clinical characteristics, management strategies and long-term outcomes between the 2 groups.
Results
There were 74 patients (3.0%) with upper extremities DVT and 2498 patients (97%) with lower extremities DVT. Patients with upper extremities DVT more often had active cancer at diagnosis (58%) and central venous catheter use (22%). The proportion of concomitant PE at diagnosis was lower in patients with upper extremities DVT than in those with lower extremities DVT (14% and 51%, P<0.001). Discontinuation of anticoagulation therapy was more frequent in patients with upper extremities DVT (63.8% and 29.8% at 1-year, P<0.001). The cumulative 3-year incidence of recurrent VTE was not different between the 2 groups (9.8% and 7.4%, P=0.43) (Figure). After adjusting confounders, the risks of upper extremities DVT relative to lower extremities DVT for recurrent VTE remained insignificant (HR 0.94, 95% CI 0.36–2.01, P=0.89).
Kaplan-Meier event curves for recurrence
Conclusions
The prevalence of patients with DVT in upper extremities was 3.0% in the current large-scale real-world registry. Patients with DVT in upper extremities more often had active cancer at diagnosis and central venous catheter use as a transient risk factor for VTE, and less often had concomitant PE. Patients with DVT in upper extremities had similar long-term risk for recurrent VTE as those with DVT in lower extremities despite shorter duration of anticoagulation.

Abstract
Abstract
Objective
In patients with epilepsy, research is variable with regard to language difficulties. Previous research generally focuses on phonemic and semantic verbal fluency in pediatric populations post-surgery; however, few studies examine category switching accuracy. This study compared phonemic fluency, categorical fluency, switching accuracy, and the number of switches among pre-surgical and post-surgical groups.
Methods
Participants included 31 epilepsy patients (age 5-20 years old; M = 12.23 years pre-surgery; M = 14.72 years post-surgery; 20 males, 11 females) who underwent neuropsychological evaluations prior to and following open brain resection surgery (i.e., temporal lobectomy, temporal resection, frontal lobectomy). Verbal Fluency was assessed by the Delis-Kaplan Executive Functioning System (D-KEFS), measuring phonemic fluency, categorical fluency, switching accuracy, and the number of switches.
Results
Statistically significant differences were found between groups on the D-KEFS Verbal Fluency subtest using a one-way ANOVA. Specifically, switching accuracy decreased following surgery, F(1,25) = 6.470, p = 0.02 (M = 104.44 pre-surgery, M = 89.44 post-surgery). Further, a downward trend was noted regarding the number of switches between the two groups, F (1, 26) = 3.172, p = 0.09; however, no differences were found in phonemic, F(1,34) = 0.854, p = 0.63, and categorical, F(1,35) = 0.828, p = 0.37, fluency tasks.
Conclusions
Results from this study revealed a decrease in the participants ability to accurately switch between verbal categories following brain resection surgery. Similarly, a downward trend was noted for number of switches completed pre- and post- surgery. Consistent with previous research, phonemic and semantic verbal fluency tasks remain unchanged post-surgery. Implications of this study highlight the need to assess executive functioning after surgery as it has an impact on treatment outcome and school planning.

Abstract
Abstract
Objective
Epilepsy is associated with cognitive difficulties including language and memory problems. Studies examining cognitive function in children with new onset seizures have found that they have difficulties when compared to healthy controls, but less is known about how these difficulties compare to cognitive function in children who have had seizures for longer periods. Our study compared semantic memory and verbal fluency skills in a group of pediatric patients with new onset seizures (< 12 months) to a group of presurgical epilepsy patents who had seizures for more than 12 months.
Method
Participants included 12 new onset seizure patients (age 8–15 years old; M = 12.13 years, SD = 2.4; 58.3% male), and 14 presurgical epilepsy patients (age 8-18 years old; M = 13.26 years, SD = 3.3; 64.3% male) who underwent neuropsychological evaluations as part of their standard of care. All patients were recruited from a regional children’s hospital. Outcome variables included performance on the Boston Naming Test (BNT) and Delis-Kaplan Executive Function System Verbal Fluency test, Letter (LF) and Category (CF) Fluencies.
Results
Overall intellectual ability did not differ significantly between groups. No significant differences were found between the two groups on the BNT [F (17,2) = 1.012, p = .607], LF [F (8,16) = 1.375, p = .279], or CF [F (7,17) = .544, p = .790].
Conclusions
Findings indicating no significant differences on cognitive tasks between the two groups are consistent with previous research indicating that individuals with new onset seizures often exhibit cognitive difficulties at the time their seizures begin.

Abstract
Abstract
Objective
This pilot study examines the effects of yoga therapy on anxiety, depression symptoms, inattention, and seizure frequency in children diagnosed with Epilepsy.
Data Selection
The sample consisted of 5 participants (4 male, 1 female), ages 7-12 years old, with diagnoses of generalized epilepsy, absence epilepsy, and complex partial epilepsy. Participants all had average cognitive abilities (IQ SS = 100.7; VCI SS = 106.3; PRI SS = 108.3), a diagnosis of Attention Deficit Hyperactivity Disorder (ADHD), and clinically significant levels of anxiety and depression. Participants participated in 30-45-minute-long yoga sessions over a 6-week period with 2-3 home sessions each week. Differences in hyperactivity, anxiety, depression, and inattention were measured via parent rating Likert scales (0-poor, 10-best) at 1 month, 3 months, and 6 months. Participants also completed weekly self-report measures to assess anxiety and depression (Revised Children’s Manifest Anxiety, Second Edition (RCMAS-2) and Children’s Depression Inventory, Second Edition (CDI-2)).
Data Synthesis
No significant reliable change differences were found between sessions; however, a downward trend was visible in reduction of anxiety (RCMAS-2; first session M = 16.4, last session M = 9.4) and depression symptoms (CDI-2; first session M = 52.8, last session M = 49.2). Further, parents reported a decrease in anxiety (first session M = 4.8, last session M = 6.4). No seizures were reported during the study.
Conclusions
There is no previous research using pediatric populations and yoga therapy effects on reducing seizure frequency, anxiety, depression, and attention problems. This pilot study showed promising results in reducing anxiety, and depression symptoms. Limitations of study include small sample size and attrition, which are both important to consider when conducting another study.

Abstract
Abstract
Objective
Intractable epilepsy is often associated with cognitive difficulties in the language domain. Few studies examining verbal domains of cognitive functioning indicate a small increase of verbal skills post-surgery. The current study compared Verbal IQ and Performance IQ domains in pediatric populations before and after open resection surgery.
Method
Participants included 31 epilepsy patients (age 5-20 years old; M = 12.23 years pre-surgery; M = 14.72 years post-surgery; 20 males, 11 females) who underwent neuropsychological evaluations prior to and following an open brain resection surgery (i.e., temporal lobectomy, temporal resection, frontal lobectomy). Cognitive ability was assessed by Weschler Abbreviated Scale of Intelligence (WASI) in order to analyze differences between pre-surgical and post-surgical cognitive function, specifically verbal comprehension and perceptual reasoning ability.
Results
No statistically significant differences were found, using a One-way ANOVA, between the two groups; however, a downward trend was noted for the Verbal IQ (VIQ) domain, F(1, 25) = 2.624, p = 0.118, including the verbal subtests vocabulary, F(1, 23) = 2.203, p = 0.151, and similarities, F(1, 24) = 1.678, p = 0.207. No differences or trends were noted within the Performance IQ (PIQ) domain, block design, or matrix reasoning.
Conclusions
Findings indicated that participants verbal ability decreased after epilepsy surgery when compared to prior evaluations. This is not consistent with previous research, which stated an increase in verbal abilities following surgical resection. Variable time between surgery and re-evaluation might account for discrepancies. Further, no differences in nonverbal reasoning abilities were noted. Results indicated a need for further research in open brain resection surgeries and the outcome of verbal processing.

Abstract
We developed a laser system for the spectroscopy of the clock transition in ytterbium (Yb) atoms at 578 nm based on an interference-filter stabilized external-cavity diode laser (IFDL) emitting at 1156 nm. Owing to the improved frequency-to-current response of the laser-diode chip and the less sensitivity of the IFDL to mechanical perturbations, we succeeded in stabilizing the frequency to a high-finesse ultra-low-expansion glass cavity with a simple current feedback system. Using this laser system, we performed high-resolution clock spectroscopy of Yb and found that the linewidth of the stabilized laser was less than 320 Hz.

Abstract
We study quantum interference effects of a qubit whose energy levels are continuously modulated. The qubit is formed by an impurity electron spin in a silicon tunneling field-effect transistor, and it is read out by spin blockade in a double-dot configuration. The qubit energy levels are modulated via its gate-voltage-dependent g factors, with either rectangular, sinusoidal, or ramp radio frequency waves. The energy-modulated qubit is probed by the electron spin resonance. Our results demonstrate the potential of spin qubit interferometry implemented in a silicon device and operated at a relatively high temperature.
