Abstract
INTRODUCTION The aim of the study was to examine whether disinfection of bacillus Calmette-Guerin-containing urine with etaprocohol® (ethanol 76.9-81.4 vol % and isopropanol as an additive) is safer than disinfection with sodium hypochlorite. METHOD In prospective research, safety and efficacy was analyzed in 5 patients in the etaprocohol® disinfection group and 5 patients in the sodium hypochlorite disinfection group. The primary endpoint was the temperature change after disinfection and the secondary endpoint was the unpleasantness of the odor caused by disinfection. Additionally, concentration of gas produced was also examined. Sensory tests were taken from staff who performed urine disinfection and the odor generated by disinfection was evaluated. As a safety protocol, post-BCG-treated urine is cultured to verify the negativity for mycobacteria. RESULTS Mycobacteria were disinfected in all cases. The temperature rise following disinfection was significantly higher in the sodium hypochlorite group. The sensory test outcomes were significantly worse in the group disinfected with sodium hypochlorite. The concentration of gas generated immediately after disinfection in both groups reached the maximum value and declined quickly. CONCLUSIONS Disinfection of bacillus Calmette-Guerin-containing urine with etaprocohol® was safer than disinfection with sodium hypochlorite, and an equivalent disinfection effect was achieved.

Abstract
The structure and decay of the most neutron-rich beryllium isotope, ^{16}Be, has been investigated following proton knockout from a high-energy ^{17}B beam. Two relatively narrow resonances were observed for the first time, with energies of 0.84(3) and 2.15(5) MeV above the two-neutron decay threshold and widths of 0.32(8) and 0.95(15) MeV, respectively. These were assigned to be the ground (J^{π}=0^{+}) and first excited (2^{+}) state, with E_{x}=1.31(6) MeV. The mass excess of ^{16}Be was thus deduced to be 56.93(13) MeV, some 0.5 MeV more bound than the only previous measurement. Both states were observed to decay by direct two-neutron emission. Calculations incorporating the evolution of the wave function during the decay as a genuine three-body process reproduced the principal characteristics of the neutron-neutron energy spectra for both levels, indicating that the ground state exhibits a strong spatially compact dineutron component, while the 2^{+} level presents a far more diffuse neutron-neutron distribution.

A retroreflector array, composed of a cluster of small retroreflectors, is experimentally studied for application to a Michelson-type interferometer system in the fusion plasma experiment. Such a new-type reflector has the potential to be a vital and effective tool at a spatially limited location, such as on the vacuum chamber wall of plasma experimental devices. To investigate the effect of retroreflector array on the reflected beam properties, a tabletop experiment is performed with the retroreflector array composed of 4 mm corner-cube retroreflectors and with a 320-GHz (λ ∼ 0.937 mm) submillimeter wave source. An imaging camera is utilized to measure the submillimeter wave beam profile and is scanned perpendicularly to the beam propagation direction if necessary. The experimental result exhibits a diffraction effect on the reflected beam, resulting in the emergence of discrete peaks on the reflected beam profile, as predicted in the past numerical study; however, the most reflected beam power converges on the one reflected into the incident direction, resulting from a property as a retroreflector. Furthermore, the dependence of the reflected beam on the incident beam angle is characterized while fixing the detector position, and the retroreflection beam intensity is found to vary due to the diffraction effect. Such an undesired variation of beam intensity induced by the diffraction can be suppressed with a focusing lens placed in front of the detector in the practical application to an interferometer.

Abstract
Subjecting a physical system to extreme conditions is one of the means often used to obtain a better understanding and deeper insight into its organization and structure. In the case of the atomic nucleus, one such approach is to investigate isotopes that have very different neutron-to-proton (N/Z) ratios than in stable nuclei. Light, neutron-rich isotopes exhibit the most asymmetric N/Z ratios and those lying beyond the limits of binding, which undergo spontaneous neutron emission and exist only as very short-lived resonances (about 10-21 s), provide the most stringent tests of modern nuclear-structure theories. Here we report on the first observation of 28O and 27O through their decay into 24O and four and three neutrons, respectively. The 28O nucleus is of particular interest as, with the Z = 8 and N = 20 magic numbers1,2, it is expected in the standard shell-model picture of nuclear structure to be one of a relatively small number of so-called 'doubly magic' nuclei. Both 27O and 28O were found to exist as narrow, low-lying resonances and their decay energies are compared here to the results of sophisticated theoretical modelling, including a large-scale shell-model calculation and a newly developed statistical approach. In both cases, the underlying nuclear interactions were derived from effective field theories of quantum chromodynamics. Finally, it is shown that the cross-section for the production of 28O from a 29F beam is consistent with it not exhibiting a closed N = 20 shell structure.

Abstract
INTRODUCTION Although breast milk is considered the optimal nutrition for infants, it is also the primary cause of postnatal cytomegalovirus (CMV) infection. Preterm infants with postnatal CMV infections are susceptible to a variety of life-threatening conditions. CASE SUMMARY Twin male infants were delivered via emergency caesarian section at 27 weeks' gestation secondary to maternal complete uterine rupture. The Apgar scores at 1 and 5 min were 1 and 1 for the older twin (Twin A) and 0 and 3 for the younger twin (Twin B). Their birth weights were 1203 g (+ 0.65SD) and 495 g (- 3.79SD) respectively. On day 41, laboratory blood test results for Twin B showed a moderate elevation in C-reactive protein (CRP), thrombocytopenia. CMV quantitative polymerase chain reaction (qPCR) tests in Twin B's urine and blood as well as in the mother's breast milk were positive, but stored, dried umbilical cord CMV qPCR tests were negative. Twin B was diagnosed with a postnatal CMV infection secondary to infected breast milk and ganciclovir was commenced on day 52. Treatment was switched to valganciclovir at 74 days of age, but a negative CMV-DNA level in the blood was not achieved. Postnatal CMV infection in this infant led to an exacerbation of pre-existing bronchopulmonary dysplasia (BPD) and he demised at 182 days of age. CONCLUSION Postnatal cytomegalovirus infections may lead to exacerbations of BPD. Early use of raw breast milk in preterm infants should be done with careful consideration of this potential complication.

Abstract
We report on the first proton-induced single proton- and neutron-removal reactions from the neutron-deficient ^{14}O nucleus with large Fermi-surface asymmetry S_{n}-S_{p}=18.6 MeV at ∼100 MeV/nucleon, a widely used energy regime for rare-isotope studies. The measured inclusive cross sections and parallel momentum distributions of the ^{13}N and ^{13}O residues are compared to the state-of-the-art reaction models, with nuclear structure inputs from many-body shell-model calculations. Our results provide the first quantitative contributions of multiple reaction mechanisms including the quasifree knockout, inelastic scattering, and nucleon transfer processes. It is shown that the inelastic scattering and nucleon transfer, usually neglected at such energy regime, contribute about 50% and 30% to the loosely bound proton and deeply bound neutron removal, respectively. These multiple reaction mechanisms should be considered in analyses of inclusive one-nucleon removal cross sections measured at intermediate energies for quantitative investigation of single-particle strengths and correlations in atomic nuclei.

Abstract
Periodontal disease is caused by dysbiosis of the dental biofilm and the host inflammatory response. Various pathogenic factors, such as proteases and lipopolysaccharides (LPSs) produced by bacteria, are involved in disease progression. Endotoxin tolerance is a function of myeloid cells, which sustain inflammation and promote tissue regeneration upon prolonged stimulation by endotoxins such as LPS. The role of endotoxin tolerance is gaining attention in various chronic inflammatory diseases, but its role in periodontal disease remains elusive. Oxidative stress, one of the major risk factors for periodontal disease, promotes disease progression through various mechanisms, of which only some are known. The effect of oxidative stress on endotoxin tolerance has not yet been studied, and we postulated that endotoxin tolerance regulation may be an additional mechanism through which oxidative stress influences periodontal disease. This study aimed to reveal the effect of oxidative stress on endotoxin tolerance and that of endotoxin tolerance on periodontitis progression. The effect of oxidative stress on endotoxin tolerance was analyzed in vitro using peritoneal macrophages of mice and hydrogen peroxide (H2O2). The results showed that oxidative stress inhibits endotoxin tolerance induced by Porphyromonas gingivalis LPS in macrophages, at least partially, by downregulating LPS-elicited negative regulators of Toll-like receptor (TLR) signaling. A novel oxidative stress mouse model was established using SMP30KO mice incapable of ascorbate biosynthesis. Using this model, we revealed that oxidative stress impairs endotoxin tolerance potential in macrophages in vivo. Furthermore, gingival expression of endotoxin tolerance-related genes and TLR signaling negative regulators was decreased, and symptoms of ligature-induced periodontitis were aggravated in the oxidative stress mouse model. Our findings suggest that oxidative stress may contribute to periodontitis progression through endotoxin tolerance inhibition.

Abstract
The one-neutron knockout from ^{52}Ca in inverse kinematics onto a proton target was performed at ∼230 MeV/nucleon combined with prompt γ spectroscopy. Exclusive quasifree scattering cross sections to bound states in ^{51}Ca and the momentum distributions corresponding to the removal of 1f_{7/2} and 2p_{3/2} neutrons were measured. The cross sections, interpreted within the distorted-wave impulse approximation reaction framework, are consistent with a shell closure at the neutron number N=32, found as strong as at N=28 and N=34 in Ca isotopes from the same observables. The analysis of the momentum distributions leads to a difference of the root-mean-square radii of the neutron 1f_{7/2} and 2p_{3/2} orbitals of 0.61(23) fm, in agreement with the modified-shell-model prediction of 0.7 fm suggesting that the large root-mean-square radius of the 2p_{3/2} orbital in neutron-rich Ca isotopes is responsible for the unexpected linear increase of the charge radius with the neutron number.

Abstract
BACKGROUND The ability to avoid obstacles efficiently and safely is important for older adults to prevent injuries from tripping and falling. It is important to find an optimal spatial margin between the body and an obstacle considering both safety and efficiency. One side of finding the optimal margin is to decrease the margin in terms of motor efficiency. In this study, we tested whether fingertip-contact intervention to obtain haptic feedback information to perceive the relationship between body and the environment could immediately improve spatial perception and collision avoidance behavior (an instantaneous effect). METHODS Twenty-seven older adults (12 males and 15 females) participated in the experiment. In the intervention of the fingertip-contact group, they lightly touched the edge of a door with both fingertips while walking. The test task before and after the intervention involved grasping a horizontal bar and passing through a narrow opening. As dependent variables, we measured the spatial margin and the collision rate. RESULTS The fingertip-contact group showed a significant decrease in the spatial margin after the intervention. On the other hand, there was no significant improvement in the collision rate after the intervention but rather a decrease only in the control group. CONCLUSION The results obtained in this study indicate that touching obstacles with the fingertips had an instantaneous effect, leading to efficient movement learning, although a possible side effect of an increased collision rated was also found. The proposed intervention might promote an efficiency-based strategy due to learning the spatial relationship between the body and the environment, and it may suppress the excessive avoidance of older adults.

Abstract
A new 320 GHz solid-state source interferometer is installed in the Heliotron J helical device to explore the physics of high-density plasmas (ne > 2-3 × 1019 m-3, typically) realized with advanced fueling techniques. This interferometry system is of the Michelson type and is based on the heterodyne principle, with two independent solid-state sources that can deliver an output power of up to 50 mW. A high time resolution measurement of <1 µs can be derived by tuning the frequency of one source in the frequency range of 312-324 GHz on the new system, which can realize the fluctuation measurement. We successfully measured the line-averaged electron density in high-density plasma experiments. The measured density agreed well with a microwave interferometer measurement using a different viewing chord, demonstrating that the new system can be used for routine diagnostics of electron density in Heliotron J.

Abstract
Background
Patients with hypertrophic cardiomyopathy (HCM) are at high risk of lethal arrhythmias, and implantable cardioverter defibrillators (ICD) are widely used for prevention of sudden cardiac death (SCD). Apical HCM is a phenotype variant of HCM, with hypertrophy predominantly affecting apex, that was initially described 30 years ago. Apical HCM patients may have different clinical prognosis compared with other subsets of HCM. In previous studies, apical HCM patients seem to have a more benign prognosis than other types of HCM. However, little is known about the long-term outcomes of apical HCM patients and there are many unclear points. Moreover, there are few reports about the clinical prognosis in apical HCM patients with an ICD.
Objective
The aim of this study is to identify the difference between the prognosis of apical and the other types of HCM patients with an ICD.
Methods
We retrospectively analyzed the database of our ICD clinic. All subjects underwent ICD implantation between October 2006 and September 2018. We classified HCM patients into LV outflow tract obstruction (LVOTO) and midventricular obstruction (MVO), apical HCM and other non-obstructive types. We divided all the patients into apical and other types of HCM, and examined their background, incidence of appropriate ICD therapies, hospitalization for heart failure, electrical storm and death.
Results
A total of consecutive 64 Japanese HCM patients with an ICD (follow-up period, 86±24 months; age, 65±14 years; male sex, 83%; left ventricular ejection fraction, 56±14%; LV max wall-thickness, 19±7mm; LV apical aneurysm, 9.4%; 5-year risk of SCD, 4.4±2.1) were enrolled in this study. We classified them into 14 apical HCM and 50 other types of HCM patients. The clinical characteristics and major clinical events of these patients are shown in the Table 1. During the follow-up periods, there were no significant differences in the incidence of electrical storm, hospitalization for heart failure and death between the 2 groups (p=0.11; p=0.60; p=0.39). Appropriate ICD therapies occurred in 6 of 14 (43%) patients with apical HCM and 5 of 50 (10%) patients with other types of HCM (p=0.010). The risk factors of patients with apical HCM patients are shown in Table 2.
Conclusions
Appropriate ICD therapy was more prevalent in patients with apical HCM, compared to patients with other types of HCM. Aggressive intervention such as catheter ablation for ventricular tachycardia and ventricular fibrillation may be considered in patients with apical HCM and higher score of 5-year risk of SCD. Further studies are needed to clarify the manifestations and long-term outcome of apical HCM patients.

Abstract
Abstract
Background
For decades, ICD is a well-established therapy for improving prognosis of structural heart disease with severe cardiac dysfunction, and ICD for primary prophylaxis against sudden cardiac death were routinely provided. However, long-term prognosis and clinical course are different in each individual patient with an ICD, and it is moreover unclear what kind of factors might have influences on their clinical outcomes.
Purpose
The aim of this study is to clarify long-term prognosis and predictors of future major adverse cardiac events (MACEs) in HFrEF patients with an ICD as primary prophylaxis in Japanese population.
Methods
We retrospectively analyzed our ICD database. Patients underwent primary prophylactic ICD implantation from 2006 to 2020 at our institute and met the criteria of ICD recommendation of the latest Japanese guideline. Its requirements are receiving optimal medication therapy, symptomatic heart failure (New York Heart Association classification II or greater), and severe cardiac dysfunction (left ventricular ejection fraction (LVEF) is 35% or less). Additionally, prior NSVT is considered Class I ICD recommendation. In the case of ischemic cardiomyopathy (ICM), ICD implantation was done at least 40 days after myocardial infarction and at least 90 days after revascularization. MACEs were defined as composite outcome of cardiovascular death, heart failure hospitalization, and appropriate ICD therapies.
Results
A total of 148 consecutive patients were enrolled (male, 120 (81%); age, 62.1±11.8 years; LVEF, 23.0±5.86%; left ventricular end-diastolic diameter (LVDd), 67.6±9.26mm; paroxysmal or persistent atrial fibrillation (AF), 38 (26%); NSVT, 113 (76%); use of class III antiarrhythmic drugs, 48 (32%); ICM, 49 (33%); cardiac resynchronization therapy (CRT), 63 (43%)). One hundred twenty patients (81%) were programmed with a shock-only zone over 200 beats per minute. The median follow-up duration was 58.5 months. Among those 148 patients, MACEs were occurred to 60 patients (41%). As a result of dividing all patients into two groups by the occurrence of MACE, LVEF and LVDd were worse in MACE(+) group, whereas, MACE(−) had greater number of co morbidities. The results of cox-regression analysis showed LVDd (HR: 1.07, 95% CI: 1.03–1.12, p<0.001), AF (HR: 2.88, 95% CI: 1.56–5.31, p<0.001) and ICM (HR: 1.78, 95% CI: 1.00–3.16, p=0.049) were the independent predictors of MACEs (Table). However, initial ICD programming was not related to the occurrence of MACE.
Conclusions
The incidence of MACEs in patients with an ICD and severe HFrEF was substantially high in this Japanese population. Etiology of ICM, left ventricle size, and AF were the potential risk factors for future MACEs.

Abstract
BACKGROUND There is growing evidence that neuroinflammation may contribute to schizophrenia neuropathology. Elevated pro-inflammatory cytokines are evident in the midbrain from schizophrenia subjects, findings that are driven by a subgroup of patients, characterised as a "high inflammation" biotype. Cytokines trigger the release of antibodies, of which immunoglobulin G (IgG) is the most common. The level and function of IgG is regulated by its transporter (FcGRT) and by pro-inflammatory IgG receptors (including FcGR3A) in balance with the anti-inflammatory IgG receptor FcGR2B. Testing whether abnormalities in IgG activity contribute to the neuroinflammatory abnormalities schizophrenia patients, particularly those with elevated cytokines, may help identify novel treatment targets. METHODS Post-mortem midbrain tissue from healthy controls and schizophrenia cases (n = 58 total) was used to determine the localisation and abundance of IgG and IgG transporters and receptors in the midbrain of healthy controls and schizophrenia patients. Protein levels of IgG and FcGRT were quantified using western blot, and gene transcript levels of FcGRT, FcGR3A and FcGR2B were assessed using qPCR. The distribution of IgG in the midbrain was assessed using immunohistochemistry and immunofluorescence. Results were compared between diagnostic (schizophrenia vs control) and inflammatory (high vs low inflammation) groups. RESULTS We found that IgG and FcGRT protein abundance (relative to β-actin) was unchanged in people with schizophrenia compared with controls irrespective of inflammatory subtype. In contrast, FcGRT and FcGR3A mRNA levels were elevated in the midbrain from "high inflammation" schizophrenia cases (FcGRT; p = 0.02, FcGR3A; p < 0.0001) in comparison to low-inflammation patients and healthy controls, while FcGR2B mRNA levels were unchanged. IgG immunoreactivity was evident in the midbrain, and approximately 24% of all individuals (control subjects and schizophrenia cases) showed diffusion of IgG from blood vessels into the brain. However, the intensity and distribution of IgG was comparable across schizophrenia cases and control subjects. CONCLUSION These findings suggest that an increase in the pro-inflammatory Fcγ receptor FcGR3A, rather than an overall increase in IgG levels, contribute to midbrain neuroinflammation in schizophrenia patients. However, more precise information about IgG-Fcγ receptor interactions is needed to determine their potential role in schizophrenia neuropathology.

Abstract
BackgroundCytomegalovirus (CMV) infection is one of serious opportunistic infections for immunosuppressed patients, therefore, identifying patients at risk for CMV infection is of importance. However, no prospective study about CMV infection in systemic rheumatic disease has been reported.ObjectivesTo identify risk factors relevant with CMV infection in patients with systemic rheumatic disease during intensive remission induction therapy.MethodsConsecutive systemic rheumatic disease cases who started intensive immunosuppressive therapy from February 2017 until February 2019 were enrolled. Serum CMV-IgG was measured before the induction therapy, and subsequently, CMV pp65 antigen was monitored weekly. Patients were divided into 2 groups according to the presence or absence of CMV infection, and risk factors for CMV infection were analyzed.Results157 patients consisting of 136 CMV-IgG positive and 21 CMV-IgG negative patients were enrolled in the study. Mean age was 60.8 ± 17.4 y/o, and female was 70.7%. The underlying diseases were following; vasculitides 54, systemic lupus erythematosus 27, polymyositis/dermatomyositis 25, rheumatoid arthritis 14, IgG4-related disease 13, mixed connected tissue disease 6, Behçet disease 5, adult-onset Still’s disease 4, and others 9. The initial dose of glucocorticoid (GC) was 48.4 ± 11.5 mg/day (0.91 ± 0.16 mg/kg/day) as prednisolone (PSL) with additional methylprednisolone (mPSL) pulse therapy being conducted in 44 (28.0%). Concomitant immunosuppressive therapies were intravenous cyclophosphamide (IVCY) in 55, calcineurin inhibitor 27, mycophenolate mofetil 16, hydroxychloroquine 5, and methotrexate 4. Concomitant biological agents were rituximab 12, tocilizumab 6, infliximab 2, golimumab 1, and abatacept 1. CMV infection occurred in 52 patients (33.1%), and all of them were CMV-IgG positive before induction therapy (38.2% in the CMV-IgG positive patients). Univariable analysis revealed initial PSL dose >0.91 mg/kg/day (odds ratio [OR] 5.2, p<0.01), IVCY (OR 3.4, p<0.01), diabetes mellitus (OR 5.2, p<0.01), and a history of malignancy (OR 2.9, p=0.02) were independent risk factors for CMV infection. CMV antiviral drugs were administered in 22 patients (42.3%). At the first detection of CMV pp65 antigen, PSL dose ≥37.5 mg/day (OR 5294.8, p<0.01), CMV pp65 antigen-positive cells ≥2 cells/2 slides (OR 16.0, p = 0.04), and serum albumin levels <3.0 g/dL (OR 26.3, p=0.01) were associated with subsequent CMV antiviral drug administration.ConclusionCMV infection occurred only in CMV-IgG positive patients with systemic rheumatic diseases who were undergoing intensive remission induction therapy. CMV infection was related with treatment regimen and comorbidities, and the necessity of CMV antiviral treatment was predicted with prednisolone dose, the number of CMV pp65 antigen positive cells, and albumin levels at the first detection of CMV pp65 antigen.Disclosure of InterestsNone declared

Abstract
BackgroundGenome-wide association studies (GWASs) have identified 29 disease-associated single nucleotide polymorphisms (SNPs) for systemic sclerosis (SSc) in non-human leukocyte antigen (HLA) regions (1-7). While these GWASs have clarified genetic architectures of SSc, study subjects were mainly Caucasians limiting application of the findings to Asians.ObjectivesThe study was conducted to identify novel causal variants for SSc specific to Japanese subjects as well as those shared with European population. We also aimed to clarify mechanistic effects of the variants on pathogenesis of SSc.MethodsA total of 114,108 subjects comprising 1,499 cases and 112,609 controls were enrolled in the two-staged study leading to the ever-largest Asian GWAS for SSc. After applying a strict quality control both for genotype and samples, imputation was conducted using the reference panel of the phase 3v5 1,000 genome project data combined with a high-depth whole-genome sequence data of 3,256 Japanese subjects. We conducted logistic regression analyses and also combined the Japanese GWAS results with those of Europeans (6) by an inverse-variance fixed-effect model. Polygenicity and enrichment of functional annotations were evaluated by linkage disequilibrium score regression (LDSC), Haploreg and IMPACT programs. We also constructed polygenic risk score (PRS) to predict SSc development.ResultsWe identified three (FCRLA-FCGR, TNFAIP3, PLD4) and four (EOMES, ESR1, SLC12A5, TPI1P2) novel loci in Japanese GWAS and a trans-population meta-analysis, respectively. One of Japanese novel risk SNPs, rs6697139, located within FCGR gene clusters had a strong effect size (OR 2.05, P=4.9×10-11). We also found the complete LD variant, rs10917688, was positioned in cis-regulatory element and binding motif for an immunomodulatory transcription factor IRF8 in B cells, another genome-wide significant locus in our trans-ethnic meta-analysis and the previous European GWAS. Notably, the association of risk allele of rs10917688 was significant only in the presence of the risk allele of the IRF8. Intriguingly, rs10917688 was annotated as one enhancer-related histone marks, H3K4me1, in B cells, implying that FCGR gene(s) in B cells may play an important role in the pathogenesis of SSc. Furhtermore, significant heritability enrichment of active histone marks and a transcription factor C-Myc were found in B cells both in European and Japanese populations by LDSC and IMPACT, highlighting a possibility of a shared disease mechanism where abnormal B-cell activation may be one of the key drivers for the disease development. Finally, PRS using effects sizes of European GWAS moderately fit in the development of Japanese SSc (AUC 0.593), paving a path to personalized medicine for SSc.ConclusionOur study identified seven novel susceptibility loci in SSc. Downstream analyses highlighted a novel disease mechanism of SSc where an interactive role of FCGR gene(s) and IRF8 may accelerate the disease development and B cells may play a key role on the pathogenesis of SSc.References[1]F.

Abstract
BackgroundThe SARS-CoV-2 messenger RNA (mRNA) vaccines BNT162b2 (Pfizer-BioNTech) and mRNA-1273 (Moderna) have benefitted all countries amid the coronavirus disease 2019 (COVID-19) crisis. Whereas both of them have shown efficacy in preventing COVID-19 illness in healthy participants, there is paucity of data about immunogenicity and safety of mRNA COVID-19 vaccines in patients with autoimmune, inflammatory rheumatic disease. Recent observational studies evaluated mainly BNT162b2, suggesting that glucocorticoids, immunosuppressive agents impair SARS-CoV-2 vaccine responses. However, difference in immune reactions and safety between BNT162b2 and mRNA-1273 have not been clarified in patients with inflammatory rheumatic diseases.ObjectivesTo assess humoral and T cell immune responses and safety profiles after two doses of different mRNA vaccine against SARS-CoV-2; BNT162b2 and mRNA-1273.MethodsWe enrolled consecutive, previously uninfected patients with inflammatory rheumatic diseases receiving mRNA vaccine including BNT162b2 and mRNA-1273. Healthy participants receiving BNT162b2 were also recruited as control. Blood samples were obtained 3weeks, 2 months, 3 months, 4 months, and 6 months after second dose of vaccines. We measured titres of neutralizing antibodies against SARS-CoV-2 and calculated seroconversion rates to evaluate humoral responses. We also assessed T-cell immunity responses by using interferon releasing assay against SARS-CoV-2 in a part of the patients. Answers to questionnaires about adverse reactions were obtained from participants.ResultsA total of 974 patients with inflammatory rheumatic diseases and healthy 630 control participants were enrolled. Among them, 796 patients received BNT162b2, 178 patients received mRNA-1273, and all control participants received BNT162b2. Seroconversion rates and neutralizing antibody titres 3 weeks after vaccination were significantly higher in patients with mRNA-1273 and healthy participants with BNT162b2 compared with patients with BNT162b2; seroconversion rates, 97.2% vs 99.5% vs 83.3%, p<0.001; titers of neutralizing antibodies, 29.4±33.9 IU/mL vs 23.9±14.2 IU/mL vs 10.8±16.5 IU/mL, p<0.001, respectively. On another front, T cell reaction against SARS-CoV-2 was similar in both patients with mRNA-1273 and BNT162b2; interferon gamma levels for antigen 1, 1.2±2.1 IU/mL vs 0.8±2.5 IU/mL, p=0.23; and for antigen 2, 1.4±1.9 IU/mL vs 1.0±2.1 IU/mL, p=0.11, respectively. Regarding adverse reaction of each mRNA vaccine, the frequency of systemic adverse reactions including fever and general fatigue are also significantly higher in patients with mRNA-1273 and healthy controls than patients with BNT162b2; fever, 48.0% vs 44.9% vs 10.2%, p<0.001; general fatigue, 70.4% vs 61.8% vs 31.2%, p<0.001, respectively). In longitudinal measurement, neutralizing antibody titres in patients with BNT162b2 were decreased more rapidly than those in healthy controls; 3.3±3.2 IU/mL in patients with BNT162b2 at 4 months and 3.2±4.7 IU/mL in healthy controls with BNT162b2 at 6 months. We identified age, glucocorticoid dose (prednisolone > 7.5mg), use of immunosuppressants including methotrexate, mycophenolate, cyclophosphamide, and tacrolimus are associated with rapid attenuation of humoral responses in patients with BNT162b2.ConclusionOur results demonstrated a significant higher humoral immunogenicity and frequency of systemic adverse reaction of the SARS-CoV-2 mRNA-1273 (Moderna) compared with the BNT162b2 (Pfizer-BioNTech) in inflammatory rheumatic disease patients. Glucocorticoid and immunosuppressive agents impaired induction and sustention of neutralizing antibody, and earlier third booster vaccination may be required within 4 months, especially for those receiving BNT162b2.References[1]Steensels D, Pierlet N, Penders J et al.

Background
Right ventricular fractional area change (RVFAC) as right ventricular function is recently referred as an independent predictor of sudden cardiac death (SCD). The purpose of this study was to evaluate the association of RVFAC and appropriate ICD therapy in order to determine the cut-off value of RVFAC.
Methods
Consecutive patients who underwent initial ICD implantation for any diseases except for non-dilated phase hypertrophic cardiomyopathy and channelopathy were retrospectively enrolled from 2012 to 2018. Primary endpoint was an initial appropriate ICD therapy. Transthoracic echocardiographic parameters before ICD implantation were evaluated by one physician and one echocardiologist to be validated. Right ventricular dimensions and function were also measured to be analyzed.
Results
In total, 172 patients (60.3±13.6 years, 131 males) including 63 ischemic cardiomyopathy were enrolled. Ninety patients received an ICD as a secondary prophylaxis. Mean LVEF and RVFAC were 38.3±14.3% and 35.8±8.82%, respectively. There was little correlation between RVFAC and LVEF (correlation coefficient =0.274). Regarding appropriate ICD therapy events, the best cut-off value of RVFAC was 34.8%. The odds ratio of low RVFAC was 2.731 (95%CI: 1.456-5.121, P=0.00174). Secondary prophylactic cohort with low RVFAC showed highest incidence of appropriate ICD therapy as shown in the figure. In multivariate analysis, only low RVFAC is an independent predictor of appropriate ICD therapy (HR: 3.53, 95%CI:1.78- 6.99, P=0.0003).
Conclusion
Low RVFAC seemed independently associated with increased appropriate ICD therapy.

Background
Non-sustained ventricular tachycardia (NSVT) is frequent phenomenon in severe heart failure with reduced ejection fraction (HFrEF) patients, and causes any negative impacts on such patients. In the Japanese Circulation Society (JCS) and Japanese Heart Rhythm Society (JHRS) guidelines, NSVT is regarded as a major component of indication for implantable cardioverter defibrillator (ICD) implantation. However, the long-term prognostic significance of NSVT in severe HFrEF is incompletely resolved.
Purpose
The aim of this study is to investigate the relation between prior NSVT episodes and major adverse cardiac events (MACEs) in HFrEF patients with an ICD as primary prophylaxis.
Methods
We retrospectively analyzed our ICD database. Patients underwent primary prophylactic ICD implantation from 2007 to 2018 following ICD recommendation of JCS and JHRS guidelines. Patients met the criteria of receiving optimal medication therapy, symptomatic heart failure (New York Heart Association classification II or greater), and severe cardiac dysfunction (left ventricular ejection fraction (LVEF) is 35% or less). In the case of ischemic cardiomyopathy (ICM), implantation of ICD was done at least 40 days after myocardial infarction and at least 90 days after revascularization. Incidence of NSVT episodes were identified through daily electrocardiogram (ECG), Holter ECG or monitor ECG in the hospital. MACEs were defined as composite outcome of cardiovascular death, heart failure hospitalization, and appropriate ICD therapies.
Results
A total of 148 consecutive patients were enrolled (male, 120 (81%); age, 62.1±11.8 years; LVEF, 23.0±5.86%; left ventricular end-diastolic diameter (LVDd), 67.6±9.26mm; paroxysmal or persistent atrial fibrillation (AF), 38 (26%); NSVT, 113 (76%); use of class III antiarrhythmic drugs, 48 (32%); ICM, 49 (33%); cardiac resynchronization therapy (CRT), 63 (43%)). The median follow-up duration was 58.5 months. As a result of comparison of the Kaplan-Meier curve between NSVT group (n=113) and non-NSVT group (n=35), cardiovascular death, heart failure hospitalization, and appropriate ICD therapy were not statistically different (Figures). Of those, MACEs were occurred to 60 patients (41%). The results of cox-regression analysis showed LVDd (HR: 1.07, 95% CI: 1.03-1.12, p<0.001), AF (HR: 2.88, 95% CI: 1.56-5.31, p<0.001) and ICM (HR: 1.78, 95% CI: 1.00-3.16, p=0.049) were the independent predictors of MACEs, however NSVT was not (Table).
Conclusions
In this Japanese population, the long-term prognosis of severe HFrEF patients is considered to be comparable regardless of prior NSVT episodes. However, the incidence of MACEs in patients with severe HFrEF after ICD implantation was substantially high. ICM, left ventricle size, and atrial fibrillation were the potential risk factors for MACEs as the previous reports showed.

Abstract
Mucin in saliva plays a critical role in the hydration and lubrication of the oral mucosa by retaining water molecules, and its impaired function may be associated with hyposalivation-independent xerostomia. Age-dependent effects on salivary gland function and rheological properties of secreted saliva are not fully understood as aging is a complex and multifactorial process. We aimed to evaluate age-related changes in the rheological properties of saliva and elucidate the underlying mechanism. We performed ex vivo submandibular gland (SMG) and sublingual gland (SLG) perfusion experiments to collect saliva from isolated glands of young (12 wk old) and aged (27 mo old) female C57BL/6J mice and investigate the rheological properties by determining the spinnbarkeit (viscoelasticity). While fluid secretion was comparable in SMG and SLG of both mice, spinnbarkeit showed a significant decrease in SLG saliva of aged mice than that of young mice. There were no significant differences in GalNAc concentration between young and aged SLG saliva. Liquid chromatography/tandem mass spectrometry analysis of SLG saliva revealed that (Hex)1 (HexNAc)1 (NeuAc)1 at m/z 793.31 was the most abundant O-glycan structure in SLG saliva commonly detected in both mice. Lectin staining of salivary gland tissue showed that SLG stained strongly with Maackia amurensis lectin II (MAL II) while Sambucus nigra agglutinin (SNA) stained little, if any, SLG. The messenger RNA expression of St3gal1 that encodes an α-2,3 sialic acid sialyltransferase SIAT4-A showed a decrease in SLG of aged mice, confirmed by a Western blot analysis. Lectin blot analysis in SLG saliva revealed that the relative signal intensity detected by MAL II was significantly lower in aged SLG. Our results suggest that spinnbarkeit decreases in SLG of aging mice due to downregulation of sialic acid linked to α-2,3 sialic acid sialyltransferase expression.

Background
The visually-guided laser balloon (VGLB) is a compliant, variable-diameter balloon that delivers laser energy around the pulmonary vein (PV) ostium under real-time endoscopic visualization. However, limited data exist in Japan thus far. Therefore, we determined the safety, efficacy, and learning curve of the VGLB for PV isolation.
Methods
A total of 52 consecutive patients with paroxysmal atrial fibrillation were prospectively enrolled and divided into 3 groups (T1 = 15 patients, T2 = 15 patients, T3 = 22 patients). All patients underwent PV isolation by 2 operators using the VGLB. The operators were experienced in radiofrequency and cryothermal procedures, but not in laser ablations.
Results
Tables show the acute clinical results. Reversible phrenic nerve palsy occurred in 3.8%, with a trend towards a lower complication rate with increasing experience.
Conclusions
The VGLB was safe and effective for PV isolation, even for operators without any previous experience. Procedure time decreased after a learning curve of 30 cases. Abstract Figure. Procedural data and isolation rates

Abstract
Abstract
Background
Prophylactic use of implantable cardioverter-defibrillators (ICDs) to prevent sudden cardiac death (SCD) is widely spread all over the world in patients with hypertrophic cardiomyopathy (HCM). Apical HCM is a phenotype variant of HCM, with hypertrophy predominantly affecting apex, that was initially described 30 years ago. Apical HCM patients may have different clinical prognosis compared with other subsets of HCM. In previous studies, apical HCM patients seem to have a more benign prognosis than other types of HCM. However, little is known about the long-term outcomes of apical HCM and there are many unclear points. Moreover, there are few reports about the clinical prognosis in apical HCM patients with an ICD.
Objective
The aim of this study is to identify the difference between the prognosis of apical and the other HCM patients with an ICD.
Methods
We retrospectively analyzed the database of our ICD clinic. All subjects had been implanted with an ICD from October 2006 to August 2017. We classified HCM patients into LV outflow tract obstruction (LVOTO) and midventricular obstruction (MVO), apical HCM and other non-obstructive types. We divided all the patients into apical and other types of HCM, and examined their background, incidence of appropriate ICD therapies, hospitalization for heart failure, electrical storm and death.
Results
A total of consecutive 62 Japanese HCM patients with an ICD (follow-up period, 86±25 months; age, 67±14 years; male sex, 85%; left ventricular ejection fraction, 57±12%; LV max wall-thickness, 19±5mm; LV apical aneurysm, 9.7%; HCM Risk-SCD, 4.4±3.0) were enrolled in this study. We classified them into 14 apical HCM and 48 other types of HCM patients. The clinical characteristics and major events of these patients are shown in the Figure. During the follow-up periods, there were no significant differences in the incidence of hospitalization for heart failure, electrical storm and death between the 2 groups (p=0.40; p=0.22; p=0.23). Appropriate therapies occurred in 5 of 14 (36%) patients with apical HCM and 4 of 48 (8.3%) patients with other types of HCM (p=0.022).
Conclusions
Appropriate ICD therapy was more prevalent in patients with apical HCM, compared to patients with other types of HCM. However, the incidences of hospitalization for heart failure, electrical storm and death were not significantly different between two groups.

Abstract
Abstract
Background
Atrial fibrillation (AF) is the most common arrhythmia. AF-related stroke tends to be more severe, and the mortality rate is higher compared with stroke without AF. Recent cardiac implantable electronic devices (CIEDs) have led to an improvement in the early detection of AF episodes. Previous studies showed that AF episodes detected by CIEDs are associated with ischemic stroke. However, little is known about the relationship between new-onset AF and ischemic stroke events in Japanese patients with CIEDs who have no prior AF and take no anticoagulant therapy. ESC guidelines for the management of AF recommend the use of CHA2DS2-VASc score as class I to predict the risk of ischemic stroke in patients with AF. However, the validity of the CHA2DS2-VASc and HAS-BLED scores to predict ischemic stroke and major bleeding events in patients without AF remains unclear.
Objective
The purpose of this study was to identify the incidence of ischemic stroke and major bleeding events in CIEDs patients without AF and assess the validity of CHA2DS2-VASc and HAS-BLED scores in this population.
Methods
We retrospectively analyzed the database of our CIEDs clinic. Every 6 months, CIEDs were checked using remote monitoring system. We examined the characteristics and incidence of ischemic stroke and bleeding events. In addition, we investigated the relationship between CHA2DS2-VASc and HAS-BLED scores and the incidence of these events.
Results
We enrolled 620 consecutive patients who were followed up at our CIED clinic. We excluded patients who had a history of AF or had received anticoagulant therapies, 348 patients (follow-up period, 65±58 months; age, 70±16 years; male sex; 64%; defibrillator, 55%) were included in this study. The mean CHA2DS2-VASc and HAS-BLED scores were 2.8±1.5 points and 1.7±1.6 points, respectively. During the follow-up, 23 (6.6%) and 12 (3.4%) of 348 patients had ischemic stroke and major bleeding events, respectively. The incidence of ischemic stroke and major bleeding events stratified by the CHA2DS2-VASc and HAS-BLED scores were shown in Figure 1.
Conclusion
The risk stratification for ischemic stroke and major bleeding using the CHA2DS2-VASc and HAS-BLED scores is valid in patients without AF.

Abstract
Abstract
Background
Despite the established treatment for life-threatening arrhythmias, the implantable cardioverter-defibrillator (ICD) therapy has emerged as a major determinant of psychological distress. Previous studies have showed several approaches to assess the ICD-specific psychological distress, however, the risk factors affecting psychological functioning are relatively variable across studies, and are not well studied in Japanese population. Therefore, we prospectively investigate the risk factors affecting the psychological functioning and assess the impact of ICD therapy in Japanese patients with ICD.
Methods
We prospectively enrolled consecutive 136 patients in the present study. At the time of ICD implantation and 1 year later, all patients completed the Florida Shock Anxiety Scale (FSAS), which is a tool designed to provide a quantitative measure of ICD shock-related anxiety. In addition, patients were also examined by psychiatrists using two assessment scales, Montgomery-Åsberg Depression Rating Scale (MADRS) and Hospital Anxiety and Depression Scale (HADS).
Results
The FSAS score was significantly correlated with the MADRS and HADS scores (Figure). During 1-year follow-up, 11 patients (8.1%) received ICD therapy. Younger age was significantly associated with the FSAS and MADRS scores at registration, but ICD therapy was the only independent factor associated with the increased risk of the FSAS score at 1 year later (p-value = 0.012).
Conclusions
ICD therapy has a strong impact on psychological distress in time course of ICD implantation. To reduce unnecessary shock therapy and optimal intervention by healthcare professionals may lead to the improvement of ICD-related psychological functioning.

Abstract
Abstract
Background
Patients with vasospastic angina (VSA) who are resuscitated from sudden cardiac arrest (SCA) are at high risk of recurrent cardiovascular events. However, there are no recommendations for implantable cardioverter-defibrillator (ICD) therapy in the VSA and SCA patient guidelines.
Purpose
This study investigated the prognostic impact of ICD therapy on patients with VSA and SCA.
Methods
The present multi-center registry included 280 patients who were resuscitated from SCA and received ICD implantation as secondary prophylaxis. The patients were divided into two groups according to the presence of VSA. The primary endpoint was a composite of all-cause death and appropriate ICD therapy, including appropriate anti-tachycardia pacing and shock for recurrent ventricular arrhythmias.
Results
Of 280 patients, 51 (18%) had VSA. Among those without VSA, ischemic cardiomyopathy was the leading cause of SCA (38%), followed by non-ischemic cardiomyopathies and Brugada syndrome (Table 1). During the median follow-up period of 3.8 years, 23 (8%) patients died, and 72 (26%) underwent appropriate ICD therapy. The incidence of the primary endpoint was not significantly different between patients with and without VSA (24% vs 33%, p=0.19). Further, the incidence of the primary endpoint was not significantly different among the etiologies (Figure 1)
Conclusions
In a cohort of patients who underwent ICD implantation as secondary prophylaxis, long-term clinical outcomes were comparable between those with VSA and those with other cardiac diseases after SCA. The results suggest that ICD therapy may be considered in patients with VSA and those with other etiologies after resuscitation from SCA.

Abstract
Direct proton-knockout reactions of ^{55}Sc at ∼220 MeV/nucleon were studied at the RIKEN Radioactive Isotope Beam Factory. Populated states of ^{54}Ca were investigated through γ-ray and invariant-mass spectroscopy. Level energies were calculated from the nuclear shell model employing a phenomenological internucleon interaction. Theoretical cross sections to states were calculated from distorted-wave impulse approximation estimates multiplied by the shell model spectroscopic factors, which describe the wave function overlap of the ^{55}Sc ground state with states in ^{54}Ca. Despite the calculations showing a significant amplitude of excited neutron configurations in the ground-state of ^{55}Sc, valence proton removals populated predominantly the ground state of ^{54}Ca. This counterintuitive result is attributed to pairing effects leading to a dominance of the ground-state spectroscopic factor. Owing to the ubiquity of the pairing interaction, this argument should be generally applicable to direct knockout reactions from odd-even to even-even nuclei.

Aim
The purpose of this study was to evaluate the association of RV function and appropriate therapy of ICD.Methods: This study was a single-center retrospective cohort study. Consecutive patients who underwent ICD implantation for any diseases were enrolled except for non-dilated phase hypertrophic cardiomyopathy and channelopathy. Transthoracic echocardiographic parameters including left ventricular ejection fraction (LVEF), RV basal diameter, RV end-diastolic area, and right ventricular fractional area change (RVFAC) were evaluated. RV systolic dysfunction was defined as RVFAC <35%. Cox regression analysis was used to analyze the effects of those parameters on appropriate ICD therapy after the implantation.
Results
In total, 151 patients (60.9 ± 13.6 years, 117 males) consisting of 67 old myocardial infarction, 34 dilated cardiomyopathy, 19 cardiac sarcoidosis, and 31 others were enrolled. Eighty patients received an ICD as a secondary prophylaxis. Mean LVEF and RVFAC were 37.8 ± 13.9% and 33.2 ± 10.8%, respectively. RV systolic dysfunction was present in 86 (57.0%) patients, which was significantly associated with ICD therapy (odds ratio 2.313; 95% confidence interval 1.067-5.014; P = 0.034) according to a univariate analysis. There was no correlation between RVFAC and LVEF (correlation coefficient =0.064). Regarding the subjects LVEF > 35%, RV systolic dysfunction was an independent predictor of ICD therapy in a multivariate analysis.
Conclusion
RV systolic dysfunction was independently associated with increased ICD therapy despite of relatively preserved LVEF.

Abstract
Background:The coronavirus disease 2019 (COVID-19), caused by a novel corona virus named SARS-CoV-2, has emerged as a global pandemic. Severe inflammatory process is one of main pathogenesis of COVID-19 and this involves cytokine storm along with overactivation of macrophage. On another front, cytokine storm with macrophage activation is frequently observed in various connective tissue diseases including dermatomyositis with positive antimelanoma differentiation-associated protein 5 (anti-MDA5) autoantibodies and adult Still’s disease. Macrophage activation during inflammatory states is partially characterized by an increased serum ferritin levels and hyperferritinaemia and characteristics shared by the three diseases are a topic of interest to rheumatologists, however, no study has evaluated anti-MDA5-positive dermatomyositis and adult Still’s disease in comparison to COVID-19.Objectives:The aim of this study was to highlight the homology and heterogeneity of COVID-19, anti-MDA5 dermatomyositis, and adult Still’s disease by comparing clinical pictures of each disease in order to discuss their respective pathogeneses.Methods:We reviewed consecutive, newly diagnosed, untreated patients with COVID-19, anti-MDA5 dermatomyositis, or adult Still’s disease. We compared their clinical, laboratory, and radiological characteristics, including the prevalence of macrophage activation syndrome and lung involvement in each disease.Results:The numbers of patients with COVID-19, anti-MDA5 dermatomyositis, and adult-onset Still’s disease with hyperferritinaemia (serum ferritin ≥ 500ng/dL) who were included for main analysis were 22, 14, and 59, respectively. COVID-19 and adult Still’s disease both featured hyperinflammatory status, such as high fever and elevated serum C-reactive protein, whereas COVID-19 and anti-MDA5 dermatomyositis both presented with severe interstitial lung disease and hypoxaemia. While two-thirds of the patients in each group met the criteria for macrophage-activated syndrome that is used in systemic juvenile idiopathic arthritis, the HScore, an indicator of haemophagocytic lymphohistiocytosis, was low in anti-MDA5 dermatomyositis and COVID-19 even in severe or critical cases. The findings of chest computed tomography were similar between COVID-19 and anti-MDA5 dermatomyositis (Figure 1).Conclusion:COVID-19 shared clinical features with rheumatic diseases characterised by hyperferritinaemia, including anti-MDA5 dermatomyositis and adult Still’s disease. These findings should be investigated further in order to shed light on the pathogenesis of not only COVID-19 but also the aforementioned rheumatic diseases.References:[1]Mehta P, McAuley DF, Brown M, et al.

Abstract
Many neutron star properties, such as the proton fraction, reflect the symmetry energy contributions to the equation of state that dominate when neutron and proton densities differ strongly. To constrain these contributions at suprasaturation densities, we measure the spectra of charged pions produced by colliding rare isotope tin (Sn) beams with isotopically enriched Sn targets. Using ratios of the charged pion spectra measured at high transverse momenta, we deduce the slope of the symmetry energy to be 42<L<117 MeV. This value is slightly lower but consistent with the L values deduced from a recent measurement of the neutron skin thickness of ^{208}Pb.

Abstract
Humanized non-obese diabetic/severe combined immunodeficiency/interleukin-2 receptor-γ-null (NOD/SCID/IL2rγnull ) [humanized (huNSG)] mice engrafted with human hematopoietic cells have been used for investigations of the human immune system. However, the epigenetic features of the human regulatory T (Treg ) cells of huNSG mice have not been studied. The objective of this study was to clarify the characteristics of human Treg cells in huNSG mice, especially in terms of the epigenetic aspects. We compared the populations, inhibitory molecule expression and suppressive capacity of human Treg cells in spleens harvested from the huNSG mice 120 days after the engraftment of human umbilical cord blood CD34+ cells with human peripheral blood mononuclear cells (PBMCs). Histone modifications and enhancer of zeste homolog 2 (Ezh2), an H3K27 methyltransferase, of human Treg cells were quantified in huNSG mice and human PBMCs. The effect of Ezh2 inhibitor on human Treg cells exposed to interleukin (IL)-6 was also compared between them. Human Treg cells in the spleens of huNSG mice showed an increased proportion among CD4+ T cells, higher expressions of forkhead box protein 3 (FoxP3), cytotoxic T lymphocyte antigen 4 (CTLA-4) and glucocorticoid-induced tumor necrosis factor-related protein (GITR), a higher production of IL-10 and enhanced suppressive capacity when compared with those in human PBMCs. H3K27me3 and Ezh2 were specifically up-regulated in human Treg cells of huNSG mice in comparison with those of human PBMCs. The decrease in Treg cells induced by IL-6 exposure was attenuated in huNSG mice when compared with human PBMCs, while the difference between them was cancelled by addition of Ezh2 inhibitor. In conclusion, huNSG mice exhibit functionally augmented human Treg cells owing to enzymatic up-regulation of H3K27me3.

Abstract
The citrullinated inter-alpha-trypsin inhibitor heavy chain 4 (cit-ITIH4) was identified as its blood level was associated with the arthritis score in peptide glucose-6-phosphate-isomerase-induced arthritis (pGIA) mice and the disease activity in patients with rheumatoid arthritis (RA). This study aimed to clarify its citrullination pathway and function as related to neutrophils. In pGIA-afflicted joints, ITIH4 and cit-ITIH4 levels were examined by immunohistochemistry (IHC), immunoprecipitation (IP) and Western blotting (WB), while peptidylarginine deiminase (PAD) expression was measured by reverse transcription-quantitative polymerase chain reaction (RT-qPCR), IHC and immunofluorescent methods. The pGIA mice received anti-lymphocyte antigen 6 complex locus G6D (Ly6G) antibodies to deplete neutrophils and the expression of cit-ITIH4 was investigated by WB. The amounts of ITIH4 and cit-ITIH4 in synovial fluid (SF) from RA and osteoarthritis (OA) patients were examined by I.P. and W.B. Recombinant ITIH4 and cit-ITIH4 were incubated with sera from healthy volunteers before its chemotactic ability and C5a level were evaluated using Boyden's chamber assay and enzyme-linked immunosorbent assay (ELISA). During peak arthritic phase, ITIH4 and cit-ITIH4 were increased in joints while PAD4 was over-expressed, especially in the infiltrating neutrophils of pGIA mice. Levels of cit-ITIH4 in plasma and joints significantly decreased upon neutrophil depletion. ITIH4 was specifically citrullinated in SF from RA patients compared with OA patients. Native ITIH4 inhibited neutrophilic migration and decreased C5a levels, while cit-ITIH4 increased its migration and C5a levels significantly. Cit-ITIH4 is generated mainly in inflamed joints by neutrophils via PAD4. Citrullination of ITIH4 may change its function to up-regulate neutrophilic migration by activating the complement cascade, exacerbating arthritis.

Abstract
A kinematically complete quasifree (p,pn) experiment in inverse kinematics was performed to study the structure of the Borromean nucleus ^{17}B, which had long been considered to have a neutron halo. By analyzing the momentum distributions and exclusive cross sections, we obtained the spectroscopic factors for 1s_{1/2} and 0d_{5/2} orbitals, and a surprisingly small percentage of 9(2)% was determined for 1s_{1/2}. Our finding of such a small 1s_{1/2} component and the halo features reported in prior experiments can be explained by the deformed relativistic Hartree-Bogoliubov theory in continuum, revealing a definite but not dominant neutron halo in ^{17}B. The present work gives the smallest s- or p-orbital component among known nuclei exhibiting halo features and implies that the dominant occupation of s or p orbitals is not a prerequisite for the occurrence of a neutron halo.

Abstract
The formation of a dineutron in the ^{11}Li nucleus is found to be localized to the surface region. The experiment measured the intrinsic momentum of the struck neutron in ^{11}Li via the (p,pn) knockout reaction at 246 MeV/nucleon. The correlation angle between the two neutrons is, for the first time, measured as a function of the intrinsic neutron momentum. A comparison with reaction calculations reveals the localization of the dineutron at r∼3.6 fm. The results also support the density dependence of dineutron formation as deduced from Hartree-Fock-Bogoliubov calculations for nuclear matter.

Abstract
Background:Residual synovitis can be detected by sensitive modalities such as ultrasonography in patients with rheumatoid arthritis in clinical remission. On the other hand, a previous study has shown that ultrasound-guided treatment provides modest benefit compared to a conventional strategy aiming clinical remission in early patients. It is still unclear how discordant clinical remission is from imaging remission by ultrasonography in patients treated with biologic agentsObjectives:To clarify the discordance between clinical remission and imaging remission in patients with rheumatoid arthritis treated with biologic agents.Methods:Patients with rheumatoid arthritis who were treated with biologic agents and in clinical remission defined as disease activity score for 28 joints (DAS28)<2.6 were enrolled. All patients were performed comprehensive ultrasound examination of 44 joints as well as physical examinations. Ultrasound images of gray scale (GS) and power doppler (PD) were evaluated with a semi-quantitative score of 0-3. Imaging remission with ultrasound was defined as no PD signal detected in any joints. Clinical information was collected from their medical charts.Results:A total of 41 patients were enrolled with 22 patients treated with tumor necrosis factor (TNF)-α inhibitors and 19 with interleukin (IL)-6 inhibitors. The mean age, female ratio, the mean disease duration, and the mean duration of clinical remission were 60 years old, 87%, 5.1 years and 11.5 years. The imaging remission by ultrasonography was observed only in 51.2 %. When patients were divided according to biologic agents, baseline characteristics including median age, disease duration and clinically remission duration were comparable between both groups, while the rates of seropositivity and the stage of radiological progression was higher in IL-6 group (seropositivity, p=0.04; radiological progression, p=0.02). The mean DAS28 was 1.93 in the TNFα group and 1.02 in the IL-6 group. The discordance of clinical remission and imaging remission was observed in 28.6% of the TNFα group and 71.4% of the IL-6 group (p=0.03). The residual synovitis scores of GS and PD in 44 joints were significantly lower in the TNFα than the IL-6 group (GS, 1.1±1.8 vs 4.7 ± 4.6, p<0.01; PD, 0.6 ± 1.3 vs 3.3 ± 3.5, p<0.01, respectively). A receiver operating characteristic curve demonstrated an optimal score of DAS28 that discriminated imaging remission as 1.89 in the TNFα group and 1.25 in the IL-6 group.Conclusion:Our results showed that there was substantial discordance between clinical remission and imaging remission, especially in the patients treated with IL-6 inhibitors. In patients treated with biologic agents, clinical remission should be assessed more stringently than the usual 2.6, and ulltrasound-guided management may be useful.References:[1]Smolen JS, et al.

Abstract
Background:Sjögren’s syndrome (SS) is an autoimmune disease which is characterized by lymphocytic infiltration including CD4+IL-17 producing helper T (Th17) cells to the lacrimal and salivary glands. We previously detected anti-M3 muscarinic acetylcholine receptor (M3R) antibodies (1) and M3R reactive CD4+IFNγ producing helper T (Th1) cells (2) in SS patients. Moreover, we clarified that M3R reactive Th1 and Th17 cells had pathogenic roles in the development of auto-immune sialadenitis in SS mouse model (3).Objectives:The purpose of this study was to identify circulating M3R reactive Th17 cells among primary SS (pSS) patients, and to determine functional properties of those cells.Methods:1)Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood of 10 pSS patients, age gender matched 10 healthy controls (HC), and 5 IgG4-related disease (IgG4-RD) patients. According to their HLA-DRB1 typing, top 10 ranked 20 mer peptides from the full length of M3R, which were highly predicted to bind to each HLA molecules according to the immune epitope database website, were selected for each subjects. PBMCs were stimulated with these selected M3R peptides mixed for 40 hours, and M3R peptide reactive IL-17 secreting cells were detected by IL-17 enzyme-linked immunospot assay (ELISpot).2)PBMCs from 5 pSS patients who were positive for M3R specific IL-17 secreting cells, were stimulated with selected 12-20 mer M3R peptides separately, to identify the dominant M3R peptides responsible for IL-17 secretion by ELISpot.3)To identify whether detected IL-17 secreting cells were Th17 cells or not, isolated CD4+T cells from 3 pSS patients who were positive for M3R specific IL-17 secreting cells, were co-cultured with auto-monocyte derived dendritic cells (DCs), and stimulated with the dominant IL-17 secreting M3R peptides detected in method 2.4)Anti-M3R antibodies were examined using ELISA method.5)Clinical features were compared between M3R specific Th17 cells positive and negative pSS patients.Results:1)5 of 10 (50%) pSS patients, while none of 10 (0%) HC, and 5 (0%) IgG4-RD patients, showed significantly increased IL-17 positive spots against selected M3R peptides mixed stimulation compared with non-stimulation in ELISpot (Figure 1). M3R specific IL-17 secreting cells were detected significantly more frequently in pSS (5/10, 50%) than in HC (0/10, 0%) (p=0.03).2)All 5 pSS patients, who were positive for M3R specific IL-17 secreting cells, showed significantly increased IL-17 positive spots against M3R AA76-95 peptides.3)Co-culturing CD4+ T cells with DCs, stimulated with identified dominant M3R peptides in method 2, showed significantly increased spots, clarifying that IL-17 secreting cells were peripheral M3R reactive Th17 cells.4)Titers of anti-M3R antibodies were significantly higher among M3R reactive Th17 cells positive pSS patients than negative pSS patients.5)5 pSS patients positive for M3R reactive Th17 cells had significantly higher disease activity score (ESSDAI: 8.0±4.3) than 5 negative pSS patients (2.8±1.7) (P=0.01).Conclusion:We detected circulating M3R reactive Th17 cells in pSS patients using ELISpot, whose T cell epitopes were shown to be included in M3R AA76-95. Moreover, M3R reactive Th17 cells might correlate with higher disease activity and production of anti-M3R antibodies in pSS patients.References:[1]Tsuboi H, et al.

Abstract
The heaviest bound isotope of boron ^{19}B has been investigated using exclusive measurements of its Coulomb dissociation, into ^{17}B and two neutrons, in collisions with Pb at 220 MeV/nucleon. Enhanced electric dipole (E1) strength is observed just above the two-neutron decay threshold with an integrated E1 strength of B(E1)=1.64±0.06(stat)±0.12(sys) e^{2} fm^{2} for relative energies below 6 MeV. This feature, known as a soft E1 excitation, provides the first firm evidence that ^{19}B has a prominent two-neutron halo. Three-body calculations that reproduce the energy spectrum indicate that the valence neutrons have a significant s-wave configuration and exhibit a dineutronlike correlation.

Abstract
Detailed spectroscopy of the neutron-unbound nucleus ^{28}F has been performed for the first time following proton/neutron removal from ^{29}Ne/^{29}F beams at energies around 230 MeV/nucleon. The invariant-mass spectra were reconstructed for both the ^{27}F^{(*)}+n and ^{26}F^{(*)}+2n coincidences and revealed a series of well-defined resonances. A near-threshold state was observed in both reactions and is identified as the ^{28}F ground state, with S_{n}(^{28}F)=-199(6) keV, while analysis of the 2n decay channel allowed a considerably improved S_{n}(^{27}F)=1620(60) keV to be deduced. Comparison with shell-model predictions and eikonal-model reaction calculations have allowed spin-parity assignments to be proposed for some of the lower-lying levels of ^{28}F. Importantly, in the case of the ground state, the reconstructed ^{27}F+n momentum distribution following neutron removal from ^{29}F indicates that it arises mainly from the 1p_{3/2} neutron intruder configuration. This demonstrates that the island of inversion around N=20 includes ^{28}F, and most probably ^{29}F, and suggests that ^{28}O is not doubly magic.

Abstract
Spectroscopic factors of neutron-hole and proton-hole states in ^{131}Sn and ^{131}In, respectively, were measured using one-nucleon removal reactions from doubly magic ^{132}Sn at relativistic energies. For ^{131}In, a 2910(50)-keV γ ray was observed for the first time and tentatively assigned to a decay from a 5/2^{-} state at 3275(50) keV to the known 1/2^{-} level at 365 keV. The spectroscopic factors determined for this new excited state and three other single-hole states provide first evidence for a strong fragmentation of single-hole strength in ^{131}Sn and ^{131}In. The experimental results are compared to theoretical calculations based on the relativistic particle-vibration coupling model and to experimental information for single-hole states in the stable doubly magic nucleus ^{208}Pb.

Abstract
Background and purpose The purpose was to identify statistically factors that correlate with the presence of a colony‐stimulating factor 1 receptor (CSF1R) mutation and to reevaluate the accuracy of the current diagnostic criteria for CSF1R‐related leukoencephalopathy. Methods CSF1R testing was conducted on 145 consecutive leukoencephalopathy cases who were clinically suspected of having adult‐onset leukoencephalopathy with axonal spheroids and pigmented glia. From these, 135 cases whose detailed clinical information was available were enrolled. Forward logistic stepwise regression was performed to generate a probability model to predict a positive CSF1R mutation result. The current diagnostic criteria were also applied to our cohort and their sensitivity and specificity were calculated. Results Twenty‐eight CSF1R‐mutation‐positive cases and 107 CSF1R‐mutation‐negative cases were identified. Our probability model suggested that factors raising the probability of a CSF1R‐mutation‐positive result were younger onset, parkinsonism, thinning of the corpus callosum and diffusion‐restricted lesions. It also showed that involuntary movements and brainstem or cerebellar atrophy were negative predictors of a CSF1R‐mutation‐positive result. In our cohort, the sensitivity and specificity for ‘probable’ or ‘possible’ CSF1R‐related leukoencephalopathy were 81% and 14%, respectively. Conclusions Clinical and brain imaging features predictive of the presence of a CSF1R mutation are proposed. Consideration of these factors will help prioritize patients for CSF1R testing.

Abstract
Exclusive cross sections and momentum distributions have been measured for quasifree one-neutron knockout reactions from a ^{54}Ca beam striking on a liquid hydrogen target at ∼200 MeV/u. A significantly larger cross section to the p_{3/2} state compared to the f_{5/2} state observed in the excitation of ^{53}Ca provides direct evidence for the nature of the N=34 shell closure. This finding corroborates the arising of a new shell closure in neutron-rich calcium isotopes. The distorted-wave impulse approximation reaction formalism with shell model calculations using the effective GXPF1Bs interaction and ab initio calculations concur our experimental findings. Obtained transverse and parallel momentum distributions demonstrate the sensitivity of quasifree one-neutron knockout in inverse kinematics on a thick liquid hydrogen target with the reaction vertex reconstructed to final state spin-parity assignments.

Abstract
Abstract
Background
Atrial fibrillation (AF) is the most common type of arrhythmia. AF-related stroke tends to be more severe, and the mortality rate is higher compared with stroke without AF. The definition of AF in patients with implanted cardioverter-defibrillators (ICDs) is not clear and the appropriate treatment guideline for patients with AF episode has not established yet. Recent ICDs have led to an improvement in the early detection of AF episodes, especially in patients who are asymptomatic. Previous studies showed that atrial high-rate episodes (AHREs) detected by cardiac implantable electronic devices are associated with embolic stroke events. However, little is known about the incidence of AF and stroke events in Japanese heart failure patients with an ICD.
Objective
The purpose of this study was to identify the incidence of embolic stroke events in heart failure patients with and without AF events detected by ICDs and examine the risk factors of embolic stroke events.
Methods
We retrospectively analyzed the database of our hospital. Every 6 months, AF events were checked by ICDs. AF30 was defined as AF episodes lasting for ≥30 seconds detected by ICDs. We examined the characteristics and incidence of embolic stroke events and investigated the relationship between AF30 and the incidence of embolic stroke events.
Results
We enrolled 215 consecutive patients who had no prior AF and took no anticoagulant in this study (follow-up period, 58±35 months; age, 62±15 years; male sex, 75%). The mean CHADS2 score and CHA2DS2-VASc score were 2.4±0.8 points and 3.8±1.2 points, respectively. The mean HAS-BLED score was 2.1±1.0 points. During the follow-up, 14 of 215 patients (6.5%) had embolic stroke events. Nine patients (5.8%/year) and 5 patients (0.65%/year) had embolic stroke events with and without AF30, respectively. The comparison of characteristics among patients with and without embolic stroke events was shown in Table. In multivariate logistic regression analysis, independent predictors for embolic stroke events were new-onset episode of AF30 (odd ratio [OR] 21, 95% confidence interval [CI] 4.8–120, P<0.0001) and an enlarged left atrium ≥40mm (OR 14, 95% CI 2.2–304, P=0.0029).
Conclusions
Embolic stroke events were common in Japanese heart failure patients with an ICD. AF30 and enlarged left atrium were the risk factors of embolic stroke events in this population. Therefore, when physicians detect new-onset AF in patients with an ICD, they should consider a comprehensive assessment of the risk and benefit of prescribing an anticoagulant.

Abstract
Background
Atrial fibrillation (AF) is the most common type of arrhythmia. AF-related stroke tends to be more severe, and the mortality rate is higher compared with stroke without AF. The definition of AF in patients with cardiac implantable electronic devices (CIEDs) is not clear and the appropriate treatment guideline for patients with AF episode has not established yet. Recent CIEDs have led to an improvement in the early detection of AF episodes, especially in patients who are asymptomatic. Previous studies showed that atrial high-rate episodes (AHREs) detected by CIEDs are associated with embolic stroke events. However, little is known about the incidence of AF and stroke events in Japanese patients with CIEDs who have no prior AF and take no anticoagulant.
Objective
The purpose of this study was to identify the incidence of embolic stroke events in patients with and without AF events detected by CIEDs and examine the risk factors of embolic stroke events.
Methods
We retrospectively analyzed the database of our hospital. Every 6 months, AF events were checked by CIEDs. AF30 was defined as AF episodes lasting for ≥30 seconds detected by CIEDs. We examined the characteristics and incidence of embolic stroke events and investigated the relationship between AF30 and the incidence of embolic stroke events.
Results
We enrolled 348 consecutive patients who had no prior AF and took no anticoagulant in this study (follow-up period, 65±58 months; age, 70±16 years; male sex; 64%; defibrillator, 55%). The mean CHADS2 score and CHA2DS2-VASc score were 1.8±1.1 points and 2.8±1.5 points, respectively. The mean HAS-BLED score was 1.7±1.2 points. During the follow-up, 23 of 348 patients (6.6%) had embolic stroke events. Thirteen patients (4.1%/year) and 10 patients (0.63%/year) had embolic stroke events with and without AF30, respectively. The comparison of characteristics among patients with and without embolic stroke events was shown in Table. In multivariate logistic regression analysis, independent predictors for embolic stroke events were new-onset episode of AF30 (odd ratio [OR] 5.3, 95% confidence interval [CI] 2.2–13, P=0.0003) and an enlarged left atrium ≥40mm (OR 3.1, 95% CI 1.2–7.9, P=0.016).
Conclusions
Embolic stroke events were common in Japanese patients with CIEDs. AF30 and enlarged left atrium were risk factors of embolic stroke events in this population. Therefore, when physicians detect new-onset AF in patients with CIEDs, they should consider a comprehensive assessment of the risk and benefit of prescribing an anticoagulant.

Abstract
Abstract
Background
Leadless pacemaker (Micra, Medtronic, US) is a effective treatment for bradycardia and eliminates any malfunctions related to intravenous leads. However, some cases exhibit pericardial effusion, presumably associated to device implantation to right ventricular free-wall.
Objectives
The present study was carried out to find ECG features during ventricular pacing by Micra, which enabled to distinguish free-wall implantation from septal implantation without imaging modalities.
Methods
Consecutive 21 patients who received implantation of Micra in our facility were enrolled. Location of device in the right ventricle was evaluated using echocardiography or computed tomography in order to determine whether the device was implanted on the septum or the freewall. The difference of 12-lead ECG during ventricular pacing from Micra were analyzed between the septum group and the free wall group.
Results
According to the imaging investigation, body of Micra was clearly identifiable in 17 patients. The locations of device were classified into septum in 11 patients, free-wall in 4 patients, and indeterminate but apex in 2 patients. Further analysis regarding ECG was performed exclusively between the septum group and the free-wall group. In lead V1, peak deflection index (PDI) was significantly larger in free-wall group than septum group (0.64±0.06 vs. 0.45±0.10, P=0.005), whereas there was no difference of QRS duration, transitional zone and QRS pattern.
PDI of V1 and Location of LPM
Conclusion
PDI of V1 could be useful to predict implantation of Micra to free-wall and may potentially stratify the risk of postprocedural pericardial effusion.

Abstract
Abstract
Background
Sustained ventricular arrhythmias (VAs) and death are feared events post myocardial infarction (post-MI). Patients with heart failure post-MI have higher risk of VAs, compared to those without heart failure. Although the risk of sudden cardiac arrest and death post-MI isn't small, previous clinical trials have failed to demonstrate the benefit of early use of implantable cardioverter defibrillators. Moreover, little is known about the relationship between the acute phase and the late phase VAs in patients with heart failure post-MI.
Purpose
The aim of this study was to determine the predictors of the late phase VAs in patients with heart failure post MI.
Methods
We retrospectively analyzed our database of MI patients from January 2012 to September 2016.
Results
A total of consecutive 460 post-MI patients were included in this study (age, 67±12 year-old; male, 336 (73%); STEMI, 281 (61%)). All the patients underwent primary percutaneous coronary intervention. Of those, 90 patients (20%) had depressed left ventricular ejection fraction (LVEF) ≤35%. After a mean follow up period of 30±16 months, 45 patients (50%) had VAs after MI. Among them, 35 patients (78%) had VAs within 48 hours after MI onset, 8 patients (18%) within 7 days 48 hours later, and 21 patients (47%) more than 7 days. Cox-regression analysis showed that VAs within 7 days 48 hours later after MI onset was significantly related to sustained VAs more than 7 days after MI onset (Hazard Ratio, 4.97; 95% Confidence Interval, 1.31–18.9; p=0.019).
Conclusions
VAs in the sub-acute phase after MI predicted sustained VAs in the late phase in this population. Prompt initiation of aggressive antiarrhythmic therapies, including catheter ablation, after MI should be considered to reduce the mortality.

Abstract
The first γ-ray spectroscopy of ^{52}Ar, with the neutron number N=34, was measured using the ^{53}K(p,2p) one-proton removal reaction at ∼210 MeV/u at the RIBF facility. The 2_{1}^{+} excitation energy is found at 1656(18) keV, the highest among the Ar isotopes with N>20. This result is the first experimental signature of the persistence of the N=34 subshell closure beyond ^{54}Ca, i.e., below the magic proton number Z=20. Shell-model calculations with phenomenological and chiral-effective-field-theory interactions both reproduce the measured 2_{1}^{+} systematics of neutron-rich Ar isotopes, and support a N=34 subshell closure in ^{52}Ar.
