Abstract
Background:Pulmonary hypertension (PH) is prominent as a vascular involvement of systemic sclerosis (SSc), which remains a leading cause of death in spite of current best treatments. Recently, hemodynamic definition of PH was updated from mPAP≥25mmHg to mPAP>20mmHg and PVR≥3WU. Although new definition may improve the prognosis of PH associated with SSc by giving a chance to start management early, it may be insufficient as more than 2/3 of the pulmonary circulation is already impaired by the time of meeting the definition. Therefore, the ideal therapeutic intervention should be started at the subclinical stage of PH in SSc patients, but little is known about underlying pathological mechanisms at the stage. In this study, we investigate progression to exercise-induced PH (exPH)1), which is considered subclinical PH, in the prospective registry of high-risk population for developing PH associated with SSc.Objectives:To detect the gene expressions in peripheral blood involved in the progression of pulmonary vessel disease (PVD) at the subclinical stage of PH associated with SSc.Methods:Total of 180 patients who had not met PH criteria with Raynaud phenomenon, skin sclerosis or SSc-related autoantibody was registered. To detect the early PVD, exercise Doppler echocardiography (exDE) was carried out every 6 or 12 months for up to 6 years. The definition of exPH was maximum sPAP>40mmHg or increase in sPAP>20mmHg estimated by exDE during exercise. For gene expression analysis, total RNAs from whole peripheral blood cells were extracted by PAXgene system, and then multiplex sequencing was done. To identify candidate genes involved in the progression to exPH, random forest machine learning method was employed. Volcano plots, a scatter plots to visualize fold-changes and p-values of differentially expressed genes (DEGs) between exPH and others (exN), were also used for seeking the important genes for disease progression.Results:At the time of registration, 34.4% of patients met exPH criteria, and 15.6% of patients developed exPH during follow-up period (35.0±18.1 months). Expression of TNF gene was selected as the most useful genes to predict progression to exPH by random forest, and the accuracy of the model was about 87%. Volcano plots indicated that expressions of TMEM176A and TMEM176B were prominent (fold-change >2.4 and -log10 p-value >3.5) in exPH patients. The accuracy was improved to 90% if the expression of TNF and TMEMA/B were used for the prediction of progression to exPH. We found that statistically significant increase in the expression of TNF was eliminated at the time of fulfilling the exPH criteria, while increase in expressions of TMEM A/B were still kept.Conclusion:It was reported that TNFα drives pulmonary arterial hypertension by suppressing the BMP type-II receptor and altering NOTCH signalling2). Our findings suggest that TNFα plays important role only in the period of pre-exPH. On the other hand, increase in expressions of TMEM A/B were observed through the period of pre-exPH to post-exPH. It suggests that there are multiple phases before developing PH associated with SSc. It is very important to understand the phases for the precise treatment to arrest the progression of PVD.References:[1]R. Naeije et al., Am J resp and critical care med 187, 576-583 (2013). 2) LA.

Abstract
Background:Methotrexate (MTX) is the first-line therapy for rheumatoid arthritis (RA). The concentrations of MTX-polyglutamates (PG) in erythrocytes, an active form of MTX, are useful markers for the optimal usage of MTX in patients with RA. The concentrations of MTX-PG have been reported to be different between Japanese and Caucasians. However, the difference among Asian ethnicity remains unclear.Objectives:To examine MTX-PG concentrations in association with MTX dose during the first 24 weeks after the initiation of MTX for newly diagnosed RA patients in Japan, Korea and Taiwan.Methods:MIRACLE study is a multicenter, open-label, randomized, 48 weeks interventional study conducted in Japan, Korea and Taiwan to evaluate non-inferiority of low dose to high dose of MTX as an add-on therapy to adalimumab in 300 patients with RA who do not achieve remission after 24 weeks MTX monotherapy in stipulated dosage. In the first 24 weeks, MTX was started at 6 to 8 mg/week for newly diagnosed RA patients, and promptly escalated to the maximum tolerable dose in 12 weeks in principle. This interim data evaluation was intended to investigate the differences among countries in the relationship between MTX dose, safety and MTX-PG concentrations in erythrocytes during the first 24 weeks. The efficacy of the treatment is not included at this point.Results:A total of 166 patients (106 in Japan, 35 in Korea, 25 in Taiwan) were included in this interim data. The age at treatment initiation was 57.2 years old on average and female was 79.5%. The time course changes in total and individual MTX-PG levels differed in the three countries. At 24 weeks, whereas the mean total MTX-PG concentrations were comparable (112.9 nmol/L in Japan, 104.4 nmol/L in Korea, and 115.7 nmol/L in Taiwan) with a dose of MTX of 12.3 mg/week, 14.1 mg/week, and 12.2 mg/week, respectively, the individual MTX-PG concentrations were different. The MTX-PG1 and MTX-PG2 concentrations were lower in Korea than Japan and Taiwan whereas MTX-PG3, MTX-PG4 and MTX-PG5 concentrations were the highest in Korea.Conclusion:The distribution of short-chain and long-chain MTX-PG concentrations were various among Asian countries despite similar dose of MTX administration: NCT03505008.Disclosure of Interests:Hiroya Tamai: None declared, Yuko Kaneko Speakers bureau: AbbVie, Astellas, Ayumi, Bristol–Myers Squibb, Chugai, Eisai, Eli Lilly, Hisamitsu, Jansen, Kissei, Kirin, Pfizer, Sanofi, Takeda, Tanabe-Mitsubishi, and UCB., Grant/research support from: Sanofi, Hideto Kameda Speakers bureau: AbbVie, Pfizer, Consultant of: AbbVie, Grant/research support from: AbbVie, Eisai, Masataka Kuwana Speakers bureau: Astellas, Asahi Kasei Pharma, Boehringer- Ingelheim, Chugai, Eisai, Janssen, Mochida, Nippon Shinyaku, Ono Pharmaceuticals, Pfizer, Mitsubishi-Tanabe, Consultant of: Corbus, Grant/research support from: AbbVie, Asahi Kasei Pharma, Boehringer- Ingelheim, Chugai, Eisai, MBL, Nippon Shinyaku, Ono Pharmaceuticals, Mitsubishi-Tanabe, Yutaka Okano: None declared, Tomonori Ishii Speakers bureau: Chugai, Mitsubishi- Tanabe, Glaxo Smith Kline, Pfizer, Eli Lilly, Janssen, AbbVie, Eisai, Astellas, Kei Ikeda Speakers bureau: AbbVie, Eli Lilly, Novartis, Mitsubishi-Tanabe, Eisai, BMS, Grant/research support from: Mitsubishi-Tanabe, Hiroaki Taguchi: None declared, Shinji Sato: None declared, Toshiaki Miyamoto: None declared, Shintaro Hirata Speakers bureau: AbbVie, Asahi Kasei Pharma, Astellas, Ayumi, Bristol Myers Squibb, Chugai, Eisai, Eli Lilly, Janssen, Glaxo Smith Kline, Kissei, Pfizer, Sanofi, Mitsubishi- Tanabe, UCB, Paid instructor for: AbbVie, Mitsubishi- Tanabe, Consultant of: AbbVie, Eisai, Gilead, Grant/research support from: AbbVie, Chugai, Mitsubishi-Tanabe, UCB, Hidekata Yasuoka Speakers bureau: AbbVie, Asahi Kasei Pharma, Astellas, Daiichi- Sankyo, Eisai, Kissei, Takeda, Mitsubishi- Tanabe, Chugai, Novartis, Eli Lilly, Pfizer, Janssen, Sanofi, Teijin, Boehringer- Ingelheim, Bayer, Glaxo Smith Kline, Paid instructor for: AbbVie, Consultant of: AbbVie, Asahi Kasei, Grant/research support from: Mitsubishi-Tanabe, Takeda, Daiichi-Sankyo, Chugai, Bristol-Myers, MSD, Astellas, Toshihisa Kojima Speakers bureau: AbbVie, Pfizer, Eisai, Grant/research support from: AbbVie, Sung-Hwan Park: None declared, Kichul Shin: None declared, Han Joo Baek: None declared, Yun Jong Lee Grant/research support from: research fund, In Ah Choi Speakers bureau: Abbvie, Eizai, Grant/research support from: Abbvie, Eizai, Jinhyun Kim: None declared, Ping-Ning Hsu: None declared, Chang-Fu Kuo: None declared, Chun-Ming Huang Paid instructor for: AbbVie, Pfizer, Meng-Yu Weng Consultant of: AbbVie, Wan-Yu Sung: None declared, Wen-Chan Tsai: None declared, Tien-Tsai Cheng Paid instructor for: AbbVie, Grant/research support from: AbbVie, Takehiro Taninaga Shareholder of: Eisai Co., Ltd., Employee of: Eisai Co., Ltd., Masahiko Mori Shareholder of: Eisai Co., Ltd., Employee of: Eisai Co., Ltd., Hideaki Miyagishi Employee of: Eisai Co., Ltd., Yasunori Sato: None declared, Tsutomu Takeuchi Speakers bureau: Astellas, Abbvie, Daiichi Sankyo, Ayumi, Eisai, GlaxoSmithKline, Mitsubishi Tanabe, Chugai, Novartis, Eli Lilly, Pfizer, Bristol Myers Squibb, Janssen, UCB, TaishoToyama, Sanofi–Aventis, Nipponkayaku, Taiho, Gilead, Boehringer Ingelheim, Grant/research support from: Asahikasei, Astellas, Abbvie, Daiichi Sankyo, Ayumi, Eisai, Takeda, Mitsubishi Tanabe, Chugai, Eli Lilly, UCB, Sanofi–Aventis, Nipponkayaku, Boehringer Ingelheim

Abstract
The rare decay K_{L}→π^{0}νν[over ¯] was studied with the dataset taken at the J-PARC KOTO experiment in 2016, 2017, and 2018. With a single event sensitivity of (7.20±0.05_{stat}±0.66_{syst})×10^{-10}, three candidate events were observed in the signal region. After unveiling them, contaminations from K^{±} and scattered K_{L} decays were studied, and the total number of background events was estimated to be 1.22±0.26. We conclude that the number of observed events is statistically consistent with the background expectation. For this dataset, we set an upper limit of 4.9×10^{-9} on the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level.

Abstract
During behavioral states of immobility, sleep, and anesthesia, the hippocampus generates high-frequency oscillations called ripples. Ripples occur simultaneously with synchronous neuronal activity in the neocortex, known as slow waves, and contribute to memory consolidation. During these ripples, various neocortical regions exhibit modulations in spike rates and local field activity irrespective of whether they receive direct synaptic inputs from the hippocampus. However, little is known about the subthreshold dynamics of the membrane potentials of neocortical neurons during ripples. We patch-clamped layer 2/3 pyramidal cells in the posterior parietal cortex (PPC), a neocortical region that is involved in allocentric spatial representation of behavioral exploration and sequential series of relevant action potentials during ripples. We simultaneously monitored the membrane potentials of post hoc-identified PPC neurons and the local field potentials of the hippocampus in anesthetized mice. More than 50% of the recorded PPC neurons exhibited significant depolarizations and/or hyperpolarizations during ripples. Histological inspections of the recorded neurons revealed that the ripple-modulated PPC neurons were distributed in the PPC in a spatially non-biased fashion. These results suggest that hippocampal ripples are widely but selectively associated with the subthreshold dynamics of the membrane potentials of PPC neurons even though there is no monosynaptic connectivity between the hippocampus and the PPC.

Abstract
BACKGROUND Chronic subdural hematoma (CSDH) with cerebrospinal fluid hypovolemia syndrome (CHS) remains refractory to standard treatment with hematoma drainage by burr hole and irrigation and/or epidural blood patch. Previously, we reported the utility of middle meningeal artery (MMA) embolization for intractable CSDH. In this study, we present the usefulness of MMA embolization as a treatment for CSDHs with CHSs. CASES We present two cases of CSDHs with CHSs occurring in patients, 1 treated with burr hole craniotomy and irrigation, and the other treated with the epidural blood patch. Both patients exhibited similar-appearing bilateral relatively-thin hematomas, hyperplasia, and enhanced contrast effects in the dura mater, and extradural hygroma in the cervical portion on enhanced magnetic resonance imaging scans. Also, to reviewing prior literature and imaging findings, they had already undergone conventional treatment. We added MMA embolization treatment and they followed a good course. RESULTS Despite the known intractable outcomes of patients with CSDHs with CHSs, MMA embolization worked well in the current case series. CONCLUSION MMA embolization might be considered as a preferred therapeutic option for CSDHs with CHSs in order to buy time before the epidural blood patch starts working.

Abstract
In an emulsion-counter hybrid experiment performed at J-PARC, a Ξ^{-} absorption event was observed which decayed into twin single-Λ hypernuclei. Kinematic calculations enabled a unique identification of the reaction process as Ξ^{-}+^{14}N→_{Λ}^{10}Be+_{Λ}^{5}He. For the binding energy of the Ξ^{-} hyperon in the Ξ^{-}-^{14}N system a value of 1.27±0.21 MeV was deduced. The energy level of Ξ^{-} is likely a nuclear 1p state which indicates a weak ΞN-ΛΛ coupling.

Abstract
OBJECTIVES To determine the expression of hepatocyte growth factor (HGF) in RA biological fluids, the role of HGF in monocyte migration and the therapeutic effect of the c-Met inhibitor savolitinib in an arthritis model mice. METHODS HGF/c-Met expression in serum, SF and synovial tissues (STs) obtained from RA patients and controls, as well as RA fibroblast-like synoviocytes (FLSs), was evaluated by ELISA and immunostaining. To determine the function of HGF in RA SF, we preincubated RA SF with a neutralizing anti-HGF antibody and measured the chemotactic ability of a human acute monocytic leukaemia cell line (THP-1). Additionally, examinations were conducted of SKG mice treated with savolitinib for 4 weeks. RESULTS HGF levels in serum from RA patients were significantly higher than those in the controls and were decreased by drug treatment for 24 weeks. Additionally, the HGF level in SF from RA patients was higher than that in SF from OA patients. HGF and c-Met expression was also noted in RA STs. Stimulation of RA FLSs with TNF-α increased HGF/c-Met expression in a concentration-dependent manner, and c-Met signal inhibition suppressed production of fractalkine/CX3CL1 and macrophage inflammatory protein-1α/CCL3. When HGF was removed by immunoprecipitation, migration of THP-1 in RA SF was suppressed. In SKG mice, savolitinib significantly suppressed ankle bone destruction on µCT, with an associated reduction in the number of tartrate-resistant acid phosphatase-positive osteoclasts. CONCLUSION HGF produced by inflammation in synovium of RA patients activates monocyte migration to synovium and promotes bone destruction via a chemotactic effect and enhanced chemokine production.

Abstract
Abstract
Background/Introduction
The REAL-CAD study identified that aggressive lipid lowering with high-dose statin reduced cardiovascular events also in Japanese patients with coronary artery disease (CAD). However, data from the SPARCL trial found that the benefits of high-dose atorvastatin treatment were partially offset by an increase in haemorrhagic stroke (HS). Although meta-analysis showed statin does not increase HS in Western countries, the evidence about the relation between statin and HS in Asian countries is still conflicting. In addition, the CREDO-Kyoto score is one of the prediction scorings for bleeding after coronary revascularization and might be a useful tool for the prediction of HS in this cohort. Recognizing the risk of HS and predicting of HS in the Asian cohort is clinically important.
Purpose
This study examined the factors associated with HS using the REAL-CAD cohort. Furthermore, we evaluated the performance of the CREDO-Kyoto bleeding risk score to predict HS in this cohort. We also performed the corresponding analysis of ischaemic stroke for reference purposes.
Methods
We sub-analysed the REAL-CAD study, prospective, multicentre, randomized, open-label, blinded endpoint study, in which 13,054 Japanese patients with stable CAD were randomized to high-dose (4 mg/day) or low-dose (1 mg/day) pitavastatin. Associations for stroke were determined using competing risk models: the Fine and Gray subdistribution hazards model accounting for the competing risk of death in models of haemorrhagic and ischaemic stroke in REAL-CAD trial. Patients were categorized to low (score 0), moderate (score 1–2), and high (score>3) according to CREDO-Kyoto bleeding score for predicting of HS.
Results
The HS events in high-dose group tended to be higher than low-dose group (4mg vs. 1mg: 43 (0.7%) vs. 30 (0.5%)). The associated factors of HS on univariate analysis were non-prior myocardial (hazard ratio (HR): 0.62, 95% CI: 0.39–0.99) and non-prior cerebral (HR: 0.25, 95% CI: 0.09–0.70) infarction, atrial fibrillation (HR: 2.4, 95% CI: 1.2–4.7), prior HS (HR: 4.2, 95% CI: 1.5–11.8), anaemia (HR: 2.4, 95% CI: 1.4–4.1), and non-statins use before run-in period (HR: 0.52, 95% CI: 0.28–0.99). High-dose pitavastatin was not a correlate with HS. The multivariate analysis revealed anaemia might have a relation with HS (HR: 4.3, 95% CI: 0.90–20.6). The number of HS was the highest in the high CREDO-Kyoto bleeding score group (Figure 1, HR: 2.4, 95% CI: 1.3–4.6), whereas there was no significant difference in the number of HS between the moderate- and low-risk groups (HR: 1.4, 95% CI: 0.84–2.3).
Conclusions
High-dose pitavastatin was not associated with the incidence of HS in this large Japanese cohort with stable CAD. High CREDO-Kyoto bleeding score was associated with HS as compared with low or moderate scores, even each of the variables consisting of CREDO-Kyoto score was not associated with HS.

Abstract
Abstract
Background
Transcatheter aortic valve replacement (TAVR) has emerged as an important therapeutic option among intermediate- and high-risk patients with symptomatic severe aortic stenosis. Heart rhythm disorders frequently complicate TAVR, particularly atrial fibrillation (AF), which can affect >40% patients undergoing the procedure. There is wide variation in rates of new-onset AF (NOAF) following TAVR across the initial pivotal randomized trials and observational studies, but burden of AF in each patient is not well known. The aim of this study is to evaluate AF burden detected by continuous patch ECG monitor (WR-100; Fukuda-Denshi, Tokyo,Japan) in patients after TAVR.
Method
Among KPUM-TAVR cohort, 58 consecutive patients (mean age:85.5±5.5, 44 females) kept recording continuous patch ECG monitor for 14 days after the procedure of TAVR. We excluded 11 patients with ECG indicating AF before procedure (paroxysmal AF 5, persistent AF 6). Finally, 47 eligible patients were selected according to the study criteria. AF was defined as a presence of AF more than 30sec on ECG monitor. The incidence and burden of NOAF was assessed.
Results
We identified 9 of 47 patients (19.1%) who developed NOAF (94% of transfemoral access patients, 6% of non- transfemoral access patients). Patients developing NOAF and had higher Society of Thoracic Surgeons risk scores (5.9±3.8 vs 9.9±6.3 p=0.0187). AF was first observed from day1 to day13. Despite having a median CHA2DS2-VASc score of 5 (25th and 75th percentile: 5 to 6), only 33% of patients with NOAF were given oral anticoagulation during the follow-up.
Conclusion
By using continuous patch ECG monitor, NOAF can be identified in 19.1% of patients after TAVR, with wide variety of first onset of AF. Given the clinical significance of post-TAVR AF, additional studies are necessary to describe the optimal management strategy in this high-risk population.

Abstract
Abstract
Background/Introduction
Patients with cancer-associated venous thromboembolisms (VTEs) have a markedly higher risk of recurrence as well as bleeding, compared to those without, leading to difficulty in achieving a good risk-to-benefit balance with anticoagulation therapy. Thus, the assessment of the risk of recurrence in an individual patient is essential. The modified Ottawa score has been developed to predict the risk of recurrence in patients with cancer-associated VTEs during anticoagulation therapy, however, the validity of the score is still controversial.
Purpose
We aimed to evaluate the utility and limitations of the modified Ottawa score in the risk stratification of recurrent VTEs in patients with cancer-associated VTEs.
Methods
The COMMAND VTE Registry is a multicenter retrospective registry enrolling 3027 consecutive patients with acute symptomatic VTEs among 29 Japanese centers between January 2010 and August 2014. The present study population consisted of 614 cancer-associated VTE patients with anticoagulation therapy beyond 10 days after the diagnosis, who were divided into 3 groups; High-risk group with a modified Ottawa score ≥1, Intermediate-risk group with a score = 0, and Low-risk group with a score ≤−1. To evaluate the discriminating power of the modified Ottawa score for recurrence, we described the receiver operating characteristic curve with a C-statistic, and evaluated the positive likelihood ratio as the predictive performance of the score for recurrence in each subgroup.
Results
The high-risk group accounted for 202 patients (33%), intermediate-risk group for 269 (44%), and low-risk group for 143 (23%). During the first 6 months of anticoagulation therapy, recurrent VTEs occurred in 39 patients. The cumulative incidence of recurrent VTEs substantially increased in the higher risk categories by the modified Ottawa score (High-risk group: 13.6%, Intermediate-risk group: 5.9%, and Low-risk group: 3.0%, Log-rank P=0.02) (Figure 1). The discriminating power of the score was modest with a C-statistic of 0.63 (95% CI 0.55–0.71). The positive likelihood ratios as the predictive performance of the score were 1.71 in the high-risk group, 0.81 in the intermediate-risk group, and 0.42 in the low-risk group. Women and patients with prior VTEs had numerically higher cumulative 6-month incidences of recurrent VTEs compared with those without, while patients with lung cancer, breast cancer, and without metastasis had numerically lower cumulative 6-month incidences of recurrent VTEs. Depending on the presence or absence of each score component, the risks of recurrence seemed to differ in the low-, intermediate-, and high-risk groups.
Conclusions
The risks of recurrence in patients with cancer-associated VTEs substantially increased in the higher risk categories by using the modified Ottawa score, but the discriminating power of the score for recurrence was modest with a widely variable impact of each score component on recurrence.

Abstract
Abstract
Background
In many studies, struts coverage is defined as >0 mm of tissue overlying the stent struts by optical coherence tomography (OCT). However, this definition has never been validated using histology as the “gold standard”. The present study sought to assess the appropriate cut-off value of neointimal thickness of stent strut coverage by OCT using histology.
Methods
OCT imaging was performed on 39 human coronary arteries with stents from 25 patients at autopsy. A total of 165 cross-sectional images from 46 stents were co-registered with histology. The optimal cut-off value of strut coverage by OCT was determined. Strut coverage by histology was defined as endothelial cells with at least underlying two layers of smooth muscle cells. Considering the resolution of OCT is 10–20 μm, 3 different cut-off values (i.e. at ≥20, ≥40, and ≥60 μm) were assessed.
Results
A total of 2235 struts were evaluated by histology. Eventually, 1216 struts which were well-matched struts were analyzed in this study. By histology, uncovered struts were observed in 160 struts and covered struts were observed in 1056 struts. The broadly used definition of OCT-coverage which does not consider neointimal thickness yielded a poor specificity of 37.5% and high sensitivity 100%. Of 3 cut-off values, the cut-off value of >40 μm was more accurate as compared to >20 and >60 mm [sensitivity (99.3%), specificity (91.0%), positive predictive value (98.6%), and negative predictive value (95.6%)]
Conclusion
The most accurate cut-off value was ≥40 μm neointimal thickness by OCT in order to identify stent strut coverage validated by histology.

Abstract
Background
The proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9-I), evolocumab, reduced the risk of cardiovascular event in patients with peripheral artery disease in FOURIER trial. However, the effects of evolocumab on favorable limb outcomes in patients with critical limb ischemia (CLI) is still unclear.
Purpose
The aim of this study was to evaluate the impacts of evolocumab on favorable limb outcomes and lipid profile in patients with CLI.
Methods
This was a single center, prospective observational study. A total of 39 patients with CLI were enrolled between November 2016 to May 2019. The subjects were divided into 2 groups based on evolocumab administration: evolocumab-treated group: E group (mean 69.4±11.7 years, n=14) and evolocumab non-treated group: Non-E group (mean 74.0±8.8 years, n=25). Baseline characteristics were assessed at admission. Lipid profile was evaluated at admission, 1, 3, 6, 12 and 18 months. The primary outcome was defined 18-month amputation-free survival (AFS). The secondary outcomes were defined 18-month overall survival (OS) and wound-free limb salvage. Mean follow-up period was 18±11 months.
Results
The patients in E group had greater reduction in levels of LDL cholesterol and non-HDL cholesterol than those in Non-E group over time. The reduction in MDA-LDL level was maintained at 1, 3, 6, 12 months, respectively. The 18-month AFS rate in the E-group was significantly higher than those in the Non-E group (log-rank p=0.02). The patients receiving evolocumab had a lower hazard regarding AFS (hazard ratio, 0.12; 95% confidence interval, 0.02–0.94; P=0.043) and a higher proportion of wound-free limb salvage at 12 months (E group [92%] vs Non-E group [57%], P=0.034) and 18 months (92% vs 52%, P=0.03). Otherwise, evolocumab administration was not associated with 18-month OS (log-rank p=0.053).
Conclusions
Evolocumab administration may be associated with the favorable outcome of 18-month AFS in the patients with CLI. Additionally, long-term administration of evolocumab over 12 months may improve wound-free limb salvage.

Abstract
Abstract
Introduction
Extracellular signal-regulated kinase (ERK) modulates differentiation and maturation of adipocyte and the hypertrophy and differentiation of adipocytes affected the vascular diseases in obese. Changes in characters of adipocytes could develope the oxidative stress and inflammations. Moreover, changes in perivascular adipose tissue (PVAT) could modulate vascular tonus in obesity. However, the role of adipose ERK2 in endothelial function and characters of PVAT in obese in vivo had not been clarified, yet.
Purpose
This study aims to elucidate the role of the adipose ERK2 in endothelial-dependent relaxation (EDR) in mice model of obesity. The role of PVAT in EDR was also assessed.
Methods and results
We created adipose-specific ERK2 knock out mice (AE2KO) by crossing fatty acid binding protein 4 Cre and ERK2 flox mice and fed them with normal diet (ND) or high fat/ high sucrose diet (HFHSD) for 24 weeks. AE2KO fed with HFHSD gained more weight and revealed the heterogeneity in sizes of adipocyte in subcutaneous fat (SF). Furthermore, the mRNA levels of lipoprotein lipase, hormone-sensitive lipase, and peroxisome proliferator-activated receptor γ, which was the master genes of adipocyte differentiation, were markedly down-regulated in SF. PVAT in AE2KO with HFHSD was markedly enlarged and the mRNA expression of inflammatory adipocytokines, such as IL-1β and leptin were up-regulated. Next, we assessed EDR by acetylcholine (ACh) -induced relaxation in aortic rings with or without PVAT. EDR without PVAT was modestly decreased in AE2KO with HFHSD compared with wild type mice (WT) with HFHSD. Aortic rings with PVAT increased EDR in WT with ND. PVAT modestly decreased EDR in WT with HFHSD and mostly eliminated EDR in AE2KO with HFHSD. To assess the contraction factors released from PVAT, the solutions incubated with PVAT (SIP) were transferred to the normal aortic rings. SIP from WT with HFHSD mildly increased vascular tone and SIP from AE2KO with HFHSD further increased it. Tempol, which was superoxide scavenger, restored endothelial dysfunction with PVAT and suppressed the contraction with SIP from AE2KO with HFHSD. Fluorescence intensity of dihydroethidium stain of aorta and PVAT, which indicated that aortic and adipose superoxide production were elevated in AE2KO with HFHSD, which were mostly eliminated with tempol.
Conclusions
Adipose ERK2 selectively modulated differentiation in SF, suppressed the aortic oxidative stress and protected from endothelial dysfunction in obese. Moreover, adipose ERK2 suppressed the hypertrophy, inflammation, and oxidative stress of PVAT in obese. The oxidative stress with the inflammation in PVAT released vasoconstriction factors, which contributed to endothelial dysfunction in obese mice.

Abstract
Abstract
Background/Introduction
Patients with cancer-associated venous thromboembolisms (VTEs) are at a high risk for recurrent VTEs and are recommended to receive prolonged anticoagulation therapy if they are at a low risk for bleeding. However, there are no established risk factors for bleeding during prolonged anticoagulation therapy.
Purpose
We aimed to identify the risk factors for major bleeding during prolonged anticoagulation therapy in cancer-associated VTE patients.
Methods
The COMMAND VTE Registry is a multicenter retrospective registry enrolling 3027 consecutive patients with acute symptomatic VTEs among 29 Japanese centers between January 2010 and August 2014. After excluding those without active cancer (N=2332), patients with major bleeding (N=15), death (N=17), and lost to follow-up (N=10) within 10 days after the diagnosis, and those without anticoagulation therapy beyond 10 days after the diagnosis (N=61), the present study population consisted of 592 cancer-associated VTE patients with anticoagulation therapy beyond 10 days after the diagnosis. The outcome measurement was International Society of Thrombosis and Hemostasis (ISTH) major bleeding during anticoagulation therapy beyond 10 days, which occurred before the first discontinuation of the anticoagulation therapy. We constructed a multivariable Cox proportional hazard model to estimate the hazard ratio (HR) and 95% confidence intervals (CIs) of the potential risk factors for major bleeding. As a sensitivity analysis, we used Fine and Gray's method to estimate the HR and 95% CI, taking into account the competing risk of all-cause death.
Results
During a median follow-up period of 199 days, major bleeding occurred in 72 patients (31 patients within 3 months; 41 beyond 3 months). The cumulative incidence of major bleeding was 5.8% at 3-months, 13.8% at 1-year, 17.5% at 2-year, and 28.1% at 5-years. The most frequent major bleeding site was gastrointestinal (47%), followed by intracranial (17%) and genitourinary (11%). Major bleeding tended to occur from the sites of the cancer, however, the sites of the cancer and sites of major bleeding were not necessarily concordant. The multivariable Cox regression model demonstrated that terminal cancer (adjusted HR, 4.17; 95% CI, 2.22–7.85, P<0.001), chronic kidney disease (adjusted HR, 1.89; 95% CI 1.06–3.37, P=0.031), and gastrointestinal cancer (adjusted HR, 1.78; 95% CI, 1.04–3.04, P=0.037) were independently associated with an increased risk of major bleeding. After taking into account the competing risk of all-cause death, the multivariable Cox regression model demonstrated almost consistent results with the main analysis.
Conclusions
Major bleeding events were common during prolonged anticoagulation therapy in real-world cancer-associated VTE patients. Terminal cancer, chronic kidney disease, and gastrointestinal cancer were the independent risk factors for major bleeding.

Abstract
We present a search for the direct production of a light pseudoscalar a decaying into two photons with the Belle II detector at the SuperKEKB collider. We search for the process e^{+}e^{-}→γa, a→γγ in the mass range 0.2<m_{a}<9.7 GeV/c^{2} using data corresponding to an integrated luminosity of (445±3) pb^{-1}. Light pseudoscalars interacting predominantly with standard model gauge bosons (so-called axionlike particles or ALPs) are frequently postulated in extensions of the standard model. We find no evidence for ALPs and set 95% confidence level upper limits on the coupling strength g_{aγγ} of ALPs to photons at the level of 10^{-3} GeV^{-1}. The limits are the most restrictive to date for 0.2<m_{a}<1 GeV/c^{2}.

Abstract
In this study, we propose a method for estimating lower extremity strength from daily gait movement. Gait movement is affected by sex and gait environment. Therefore, we examined correlation coefficient between lower extremity strength and gait movement based on sex and environment and created models for estimating lower extremity strength. As a result, when only male or female data were used for model constructing, the correlation coefficient between estimates and actual measurements of lower extremity strength were approximately 0.7 and the precision had a mean absolute error of approximately 0.1 N/kg. The accuracy of the estimates was higher than that when sex was considered.

Abstract
OBJECTIVE Sesamin is a major lignan constituent of sesame and possesses various health-promoting effects. Previous studies have demonstrated that sesamin extends the lifespan of Drosophila and Caenorhabditis elegans and corrects oxidative damage-related tissue dysfunction in mammals. To understand its anti-aging effects, we aimed to determine whether sesamin restores tissue function hampered by oxidative damage and suppresses several aging-related phenotypes using Drosophila senescence-accelerated models. MATERIALS AND METHODS We elucidated the anti-aging effects of sesamin on several aging-related phenotypes in the muscle, brain and midgut using the senescence-accelerated models (Sod1n1 mutant and Sod1-depleted flies) by immunostaining experiments. We determined the expression levels of several anti-oxidative and DNA repair genes using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). We also identified the metabolite of sesamin in Drosophila by LC-MS/MS. RESULTS We confirmed that sesamin (0.35 and 2 mg/ml) extended the lifespan of the fly models. As observed in mammals, it can be absorbed and metabolized by Drosophila adults. The sesamin feeding suppressed the age-dependent impairment of locomotor activity and inhibited the accumulation of reactive oxygen species (ROS) in their bodies. Sesamin delayed the age-dependent accumulation of damaged proteins in the muscle, partially suppressed the loss of dopaminergic neurons in adult brains displaying ROS accumulation, and suppressed the accumulation of DNA damage and hyperproliferation of intestinal stem cells. Four antioxidative genes and two DNA repair genes were simultaneously upregulated in sesamin-fed adults. CONCLUSIONS: These observations represent the first direct evidence of the anti-aging effects of sesamin at the individual level. We propose that sesamin exerts anti-aging effects in the muscles, brain and midgut by inducing antioxidative and DNA repair genes, resulting in extended lifespan in flies.

Abstract
Background:Skin rashes as a side effect of Tocilizumab therapy (TCZ- Tx) has not been paid much attention, because the incidence was only 1~2% in the drug information sheets. However, we experienced several RA cases with development of various skin rashes associated with neutrophil activation after TCZ-Tx. On the other hand, it is well known that the neutrophil counts in peripheral blood decreases after TCZ-Tx, whereas it does not affect the rate of serious infections. The detailed mechanism is still unclear.Objectives:To detect the characteristics of the changes in gene expressions of peripheral blood associated with TCZ-Tx and the development of skin rashes as its side effect.Methods:Total of 14 RA patients with TCZ-Tx were included. Among them, 4 patients developed TCZ-related rashes (group S) and 10 patients did not show any side effects (group C). Peripheral whole blood at just before (pre) and 3 months after (post) TCZ-Tx from each patient were subjected to the analysis. Total RNAs were extracted with PAXgene miRNA kit and analyzed with next-generation sequencing. First, group C was investigated for the normal response to TCZ-Tx. Differentially expressed genes (DEGs) were selected by paired comparison (post vs. pre). And then, enrichment analysis using gene ontology (GO) terms were performed. Second, to explore the characteristics of group S, all expressed genes in 14 cases at just before TCZ-Tx were subjected to a hierarchical clustering analysis. The DEGs (group S vs. C and post vs. pre) were also investigated with weighted gene co-expression network analysis (WGCNA) and GO analysis. Meanwhile, the total eigengene expressions of the important modules identified by WGCNA in each cases were also calculated.Results:Surprisingly, 8 out of the top 10 enriched GO terms in the up-regulated genes were relevant to leukocyte activation such as ‘neutrophil migration” by the analysis of DEGs (post vs. pre) in group C. The cluster analysis of ‘pre’ genes confirmed that the patterns of gene expression between group S and C was different. WGCNA analysis of DEGs (group S vs. C) revealed that genes related to acute inflammation such as ‘leukocyte mediated immunity’ were activated in group S. Interestingly, it was not correlated with disease activity score (DAS) of RA. By the analysis of DEGs (post vs. pre) of upregulated genes, we found that the total eigengene expressions of the module enriched with genes related to ‘cell adhesion’ or ‘leukocyte migration’ were significantly increased in all cases of group S.Conclusion:This is the first evidence that the genes associated with neutrophil migration is significantly activated after TCZ-Tx. It is noteworthy that the gene activation was observed in cases without any side effects. The decreased neutrophil counts in peripheral blood have been known after initiation of TCZ-Tx, which did not affect the rate of serious infections. Recently, It was reported that TCZ affects neutrophil trafficking to the bone marrow1). Our findings will provide a rationale for its cause. On the other hand, we experienced several RA cases with development of various skin rashes associated with neutrophil activation after TCZ-Tx. However, majority of patients do not develop the side effect, even though genes related to ‘neutrophil migration’ are activated. In group S, our findings indicate that the genes related to ‘leukocyte mediated immunity’ was already activated at the initiation of treatment without correlating to DAS of RA, furthermore, the gene upregulation related to ‘leukocyte migration’ was more prominent after TCZ-Tx. Although it is difficult to predict the patients developing skin rashes before TCZ-Tx, we do not recommend to use TCZ for the patients with neutrophilic dermatosis which is often associated with RA.References: :[1]Lok LSCet al.,Eur J Clin Invest. 47(10):736-745 (2017).Disclosure of Interests: :Moe Sakamoto: None declared, Akemi Senoh: None declared, Yoshiharu Sato: None declared, Hiroshi Iijima: None declared, Mari Yamaguchi: None declared, Toshie Higuchi: None declared, Yoshinobu Koyama Grant/research support from: Eli-Lilly and Mochida., Speakers bureau: BMS, Ayumi, Chugai, Ono, Mitsubishi Tanabe, Abbvie and Eisai.

Abstract
Background:After accumulation of evidences, it is recognized that inhibition of IL-6 signaling is one of the most established strategies for rheumatoid arthritis (RA) treatment. Tocilizumab (TCZ), an anti-IL6 receptor monoclonal antibody, is the pioneer which blocks IL-6 signaling by preventing IL-6 from binding to both membrane-bound and soluble receptors. Tofacitinib (TOF) inhibits Janus kinase (JAK) 1, JAK3 and, to a lesser extent, JAK2. Recently, Baricitinib (BAR), JAK 1 and JAK2 selective kinase inhibitor, were also approved to treat RA. These JAK inhibitors are known to inhibit cytokine signaling including interleukin (IL)-6. It is very important for clinicians to know whether these treatments affect common biological processes or disparate, because it will provide a rationale for switching each other if one of these treatments resulted in lack of efficacy.Objectives:To compare the gene-expression modification profiles among TOF, BAR and TCZ treatments.Methods:Total of 38 RA cases were analyzed, including TOF (n=15: 6-20mg/d), BAR (n=10: 2-4mg/d) and TCZ (n=13: 8mg/kg/4w or 163mg/2w) treatment groups. Peripheral blood was drawn at just before (pre) and 3 months after (post) these treatments. Total RNAs were then extracted with using PAXgene miRNA kit. After constructing single-stranded, strand-specific libraries, multiplex sequencing was done. After quantifying the expressions of transcripts, differentially expressed genes (DEGs) were selected by paired comparison (post vs. pre), setting thresholds at 2-fold change up/down and less than P=0.05 in paired T-test. And then, hierarchical clustering analysis and enrichment analysis using gene ontology (GO) terms were performed.Results:From the comparison of post- vs. pre-treatment of TOF, BAR and TCZ, the 120 (up-regulated=25/down-regulated=95), 62 (up=20/down=42) and 193 (up=54/ down=139) genes were selected as DEGs respectively. It seems to be discrete depending on the treatment, because overlapped genes were only 1.0% in up-regulated and 5.7% in down-regulated genes. The hierarchical clustering with expression profiles of these DEGs showed major 4 clusters. 92.3% of TCZ and 70% of BAR cases were segregated into 1stand 3rdclusters respectively, while those of TOF cases fell into 2ndand 4thclusters. Disparate GO terms were enriched in each DEGs group. For example, genes relevant to viral defense including ‘response to type I interferon (IFN)’ were suppressed in TOF group. Meanwhile, down regulation of genes involved in phosphorylation process including ‘IL-7 signaling’ seemed to be significant in BAR group. It is noteworthy that terms related to wound healing such as ‘platelet activation’ were enriched in the down-regulated genes of TCZ group.Conclusion:It is speculated that the downstream biological cascade for TOF, BAR and TCZ treatment might be shared, as IL-6 signaling is mediated by JAK1/JAK2/TYK2 activation. However, the influence of these treatments over the transcriptome in the peripheral blood seems to be disparate. Enrichment analysis using GO terms also indicated that different biological processes were involved in the effect of each treatment. Our findings will support a rationale for switching each other if one of these treatments resulted in lack of efficacy. An increased risk of herpes zoster by a treatment with JAK inhibitors has been well recognized. It makes sense because IFN signaling is also mediated by JAK/STAT pathway. On the other hand, we have experienced a case with exacerbation of skin ulcer during TCZ treatment despite the activity of RA was absolutely under control. It is accounted for by the suppression of genes involved in wound healing after TCZ treatment.Disclosure of Interests: :Yoshinobu Koyama Grant/research support from: Eli-Lilly and Mochida., Speakers bureau: BMS, Ayumi, Chugai, Ono, Mitsubishi Tanabe, Abbvie and Eisai., Yoshiharu Sato: None declared, Moe Sakamoto: None declared, Hiroshi Iijima: None declared, Toshie Higuchi: None declared

Abstract
The i-STAT1 clinical analyzer has become an increasingly popular tool in clinical production animal medicine as it can provide pen-side results in a cost effective and timely manner when compared to standard benchtop serum biochemistry blood gas and chemistry analyses. This study compares the results of the portable Abbott i-STAT1 analyzer and the Abaxis VetScan VS2 for glucose (Glu, mg/dL), ionized Ca (mmol/L), Na (mmol/L), and K (mmol/L) values. Three genetically distinct commercial varieties (CV) of Hy-Line white-egg laying hens are used in this study (Hy-Line W-36, Hy-Line W-80, and Hy-Line W-80+). Thirty blood samples (n = 10 per CV) were obtained in the production house from the brachial vein and concurrently analyzed by the i-STAT1 portable device. Serum from 22 of these same samples was analyzed via VetScan VS2, a benchtop serum clinical biochemistry analyzer, using VetScan Avian/Reptilian Profile Plus reagent rotors. A paired T-test was used to test for statistical differences in means between the 2 instruments for each of the parameters. Parameters with significant mean differences were then subject to correlation and regression analysis to further evaluate relationships between the results from the 2 methods. Significant differences between means were found for Glu, Na, and K levels. Ca levels were found to be not directly comparable by the 2 analysis instruments. This comparison elucidates the importance of clinical analyzer validations when applying different strategies of diagnostic medicine in poultry.

Abstract
In ovarian cancer patients, chemotherapy can be an independent risk factor for the development of thromboembolic complications, such as venous thromboembolism (VTE). The factors and their values that lead to the development of VTE are remaining unknown in patients undergoing chemotherapy with paclitaxel and carboplatin. This study investigated serial rheological parameters (D-dimer, red blood cell count, hematocrit, and plasma viscosity) for VTE that developed following chemotherapy for ovarian cancer. Forty-eight ovarian cancer patients undergoing chemotherapy were enrolled in this study. A significant difference in the mean values of plasma viscosity and hematocrit was observed between the VTE group (n = 5) and the non-VTE group (n = 43) (P < 0.10). Univariate and multiple regression analyses by stepwise selection identified plasma viscosity as the independent variable associated with VTE development. The VTE incidence was the same as in previous reports. The results support the contention that plasma viscosity could be an index for development of VTE in ovarian cancer after chemotherapy.

Abstract
Theories beyond the standard model often predict the existence of an additional neutral boson, the Z^{'}. Using data collected by the Belle II experiment during 2018 at the SuperKEKB collider, we perform the first searches for the invisible decay of a Z^{'} in the process e^{+}e^{-}→μ^{+}μ^{-}Z^{'} and of a lepton-flavor-violating Z^{'} in e^{+}e^{-}→e^{±}μ^{∓}Z^{'}. We do not find any excess of events and set 90% credibility level upper limits on the cross sections of these processes. We translate the former, in the framework of an L_{μ}-L_{τ} theory, into upper limits on the Z^{'} coupling constant at the level of 5×10^{-2}-1 for M_{Z^{'}}≤6 GeV/c^{2}.

Abstract
Tooth formation can be affected by various factors, such as oral disease, drug administration, and systemic illness, as well as internal conditions including dentin formation. Dyslipidemia is an important lifestyle disease, though the relationship of aberrant lipid metabolism with tooth formation has not been clarified. This study was performed to examine the effects of dyslipidemia on tooth formation and tooth development. Dyslipidemia was induced in mice by giving a high-fat diet (HFD) for 12 weeks. Additionally, LDL receptor-deficient (Ldlr−/−) strain mice were used to analyze the effects of dyslipidemia and lipid metabolism in greater detail. In the HFD-fed mice, incisor elongation was decreased and pulp was significantly narrowed, while histological findings revealed disappearance of predentin. In Ldlr−/− mice fed regular chow, incisor elongation showed a decreasing trend and pulp a narrowing trend, while predentin changes were unclear. Serum lipid levels were increased in the HFD-fed wild-type (WT) mice, while Ldlr−/− mice given the HFD showed the greatest increase. These results show important effects of lipid metabolism, especially via the LDL receptor, on tooth homeostasis maintenance. In addition, they suggest a different mechanism for WT and Ldlr−/− mice, though the LDL receptor pathway may not be the only factor involved.

Abstract
We present resistivity and thermal-conductivity measurements of superconducting FeSe in intense magnetic fields up to 35 T applied parallel to the ab plane. At low temperatures, the upper critical field μ_{0}H_{c2}^{ab} shows an anomalous upturn, while thermal conductivity exhibits a discontinuous jump at μ_{0}H^{*}≈24 T well below μ_{0}H_{c2}^{ab}, indicating a first-order phase transition in the superconducting state. This demonstrates the emergence of a distinct field-induced superconducting phase. Moreover, the broad resistive transition at high temperatures abruptly becomes sharp upon entering the high-field phase, indicating a dramatic change of the magnetic-flux properties. We attribute the high-field phase to the Fulde-Ferrel-Larkin-Ovchinnikov (FFLO) state, where the formation of planar nodes gives rise to a segmentation of the flux-line lattice. We point out that strongly orbital-dependent pairing as well as spin-orbit interactions, the multiband nature, and the extremely small Fermi energy are important for the formation of the FFLO state in FeSe.

Abstract
BACKGROUND Cryopreservation of zona pellucida (ZP)-free embryos provides more options for somatic cell nuclear transfer, particularly during handmade cloning. OBJECTIVE This study investigated whether the removal of the ZP affects the development of porcine zygotes after vitrification and warming. MATERIALS AND METHODS We determined the appropriate volume of the corresponding medium for the individual culture of ZP-intact and -free embryos and evaluated the protection effect of ZP during cryopreservation on the resulting development of the vitrified-warmed zygotes. RESULTS The volume of culture medium influenced the development of ZP-intact zygotes, and a volume of 15 µL was most suitable for their development. However, the volume of culture medium did not modify the development of ZP-free zygotes. The removal of the ZP before vitrification did not adversely affect embryonic development or quality of the resulting blastocysts. CONCLUSION Our results suggest that the removal of the ZP does not cause detrimental effects to the development of vitrified-warmed zygotes.

Abstract
Aerosols interact with radiation and clouds. Substantial progress made over the past 40 years in observing, understanding, and modeling these processes helped quantify the imbalance in the Earth's radiation budget caused by anthropogenic aerosols, called aerosol radiative forcing, but uncertainties remain large. This review provides a new range of aerosol radiative forcing over the industrial era based on multiple, traceable, and arguable lines of evidence, including modeling approaches, theoretical considerations, and observations. Improved understanding of aerosol absorption and the causes of trends in surface radiative fluxes constrain the forcing from aerosol-radiation interactions. A robust theoretical foundation and convincing evidence constrain the forcing caused by aerosol-driven increases in liquid cloud droplet number concentration. However, the influence of anthropogenic aerosols on cloud liquid water content and cloud fraction is less clear, and the influence on mixed-phase and ice clouds remains poorly constrained. Observed changes in surface temperature and radiative fluxes provide additional constraints. These multiple lines of evidence lead to a 68% confidence interval for the total aerosol effective radiative forcing of -1.6 to -0.6 W m-2, or -2.0 to -0.4 W m-2 with a 90% likelihood. Those intervals are of similar width to the last Intergovernmental Panel on Climate Change assessment but shifted toward more negative values. The uncertainty will narrow in the future by continuing to critically combine multiple lines of evidence, especially those addressing industrial-era changes in aerosol sources and aerosol effects on liquid cloud amount and on ice clouds.
