Abstract
Active microrheology was conducted in living cells by applying an optical-trapping force to vigorously-fluctuating tracer beads with feedback-tracking technology. The complex shear modulus G(ω)=G'(ω)-iG″(ω) was measured in HeLa cells in an epithelial-like confluent monolayer. We found that G(ω)∝(-iω)1/2 over a wide range of frequencies (1 Hz <ω/2π <10 kHz). Actin disruption and cell-cycle progression from G1 to S and G2 phases only had a limited effect on G(ω) in living cells. On the other hand, G(ω) was found to be dependent on cell metabolism; ATP-depleted cells showed an increased elastic modulus G'(ω) at low frequencies, giving rise to a constant plateau such that G(ω)=G0+A(-iω)1/2 . Both the plateau and the additional frequency dependency ∝(-iω)1/2 of ATP-depleted cells are consistent with a rheological response typical of colloidal jamming. On the other hand, the plateau G0 disappeared in ordinary metabolically active cells, implying that living cells fluidize their internal states such that they approach the critical jamming point.

Abstract
BackgroundRheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that causes not only joint pain but also bone destruction resulting in impairment of quality of life. Tumor necrosis factor inhibitors have improved prognosis of patients with rheumatoid arthritis dramatically, especially in combination with methotrexate, however, the optimal dose of the concomitant methotrexate is unclear.ObjectivesTo evaluate the efficacy and safety of adalimumab in combination with reduced dose of methotrexate in patients with early RA with inadequate response to methotrexate.MethodsThe MIRACLE study was a multinational, randomized, open-label study in patients with RA with inadequate response to methotrexate conducted in Asia. It compared low dose and high dose methotrexate upon starting adalimumab. Methotrexate-naive patients with RA with a disease duration of less than two years started methotrexate at 6 to 8 mg/week and increased it to the maximum tolerable dose by week 12. Patients who have not achieved remission according to simplified disease activity index (SDAI) despite methotrexate ≥ 10 mg/week at week 24 were randomised to the maximum tolerable dose of methotrexate group (10 to 25 mg/week) or the reduced dose group (6 to 8 mg/week) and started to receive subcutaneous adalimumab 40 mg every other week. The primary endpoint was non-inferiority in the achievement of SDAI remission at week 48 in the reduced dose group compared with the maximum tolerable dose group with a non-inferiority margin of -15% based on two-sided 90% confidence interval. (NCT03505008)ResultsA total of 300 patients were enrolled in the study. Among them, 291 started methotrexate and were included in the analysis. The mean age was 57.7±15.2 years, female was 74.6%, and the mean disease duration from the diagnosis of RA was 21.1±56.2 days. Anti-CCP antibody was positive in 211 (73.0%) and the mean SDAI at study enrollment was 26.5±12.4. At week 24, with the mean dose of methotrexate of 12.6±2.9 mg/week, 108 patients (37.1%) achieved remission according to SDAI and continued MTX monotherapy. 134 patients (46.0%) were randomised and started adalimumab with 68 patients in the maximum tolerable dose group and 66 patients in the reduced dose group. At week 48, the remission achievement rates were 38.4 % and 44.8 %, respectively, with the adjusted risk difference of the reduced dose group to the maximum tolerable dose group of 6.4% (-7.0% to 19.8%, 90% CI), which met the criterion for noninferiority. No significant difference was found in health assessment questionnaire disability index ≤0.5 (59.1% vs 62.0%, respectively, p=0.72) and in radiological remission rates (Δmodified total Sharp score ≤0.5, 66.3% vs 62.0 %, respectively, p=0.59). Adverse drug reactions tended to be more frequent in the maximum tolerable dose group than in the reduced dose group (22.1% vs 9.1%, respectively, p=0.06).ConclusionThe MIRACLE randomised study demonstrated that, in patients with inadequate response to methotrexate, the efficacy of adalimumab with reduced dose of concomitant methotrexate was not inferior to that with maximum tolerable dose of methotrexate with better safety profile.Disclosure of InterestsHiroya Tamai Speakers bureau: Eisai, Grant/research support from: Eisai, Kei Ikeda Speakers bureau: AbbVie, Eisai, Eli Lilly, Novartis, Gilead, Asahi-Kasei, Grant/research support from: Mitsubishi-Tanabe, Toshiaki Miyamoto: None declared, Hiroaki Taguchi: None declared, Chang-Fu Kuo: None declared, Kichul Shin: None declared, Shintaro Hirata Speakers bureau: AbbVie, Asahi-Kasei, Astellas, Ayumi, Bristol Myers Squibb, Celgene, Chugai, Eisai, Eli Lilly, Gilead, Glaxo SmithKline, Janssen, Kyorin, Novartis, Pfizer, Sanofi, Tanabe-Mitsubishi, UCB, Paid instructor for: AbbVie, Mitsubishi-Tanabe, Consultant of: AbbVie, Astellas, Bristol Myers Squibb, Eisai, Gilead, Ily Lilly, Grant/research support from: AbbVie, Asahi-Kasei, Eisai, Otsuka, Sanofi, Shionogi, Chugai, Pfizer, Tanabe-Mitsubishi, Eli Lilly, UCB, yutaka okano: None declared, Shinji Sato Speakers bureau: AbbVie, Eisai, Grant/research support from: AbbVie, Eisai, 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, In Ah Choi Speakers bureau: Abbvie, Eisai, Sung-Hwan Park: None declared, Meng-Yu Weng Paid instructor for: Novartis, Eli Lilly, ChuGai, Abbvie, Consultant of: Abbvie, Masataka Kuwana Speakers bureau: Astellas, Asahi Kasei Pharma, Boehringer-Ingelheim, Chugai, Eisai, Janssen, Mochida, Nippon Shinyaku, Ono Pharmaceuticals, Pfizer, Mitsubishi-Tanabe, Consultant of: Boehringer-Ingelheim, Kissei, Mochida, Grant/research support from: AbbVie, Asahi Kasei Pharma, Boehringer-Ingelheim, Chugai, Eisai, MBL, Nippon Shinyaku, Ono Pharmaceuticals, Mitsubishi-Tanabe, Yun Jong Lee Grant/research support from: Yuhan, Tomonori Ishii Speakers bureau: Chugai, Mitsubishi-Tanabe, Glaxo Smith Kline, Pfizer, Eli Lilly, Janssen, AbbVie, Eisai, Astellas, Jinhyun Kim: None declared, Hideto Kameda Speakers bureau: AbbVie, Pfizer, Consultant of: AbbVie, Grant/research support from: AbbVie, Eisai, Toshihisa Kojima Speakers bureau: AbbVie, Pfizer, Eisai, Grant/research support from: AbbVie, Han Joo Baek: None declared, Ping-Ning Hsu: None declared, Chun-Ming Huang Paid instructor for: Abbvie, Pfizer, Tien-Tsai Cheng Paid instructor for: Abbvie, Grant/research support from: Abbvie, Wan-Yu Sung: None declared, 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 Shareholder of: Eisai.co.,Ltd., Employee of: Eisai.co.,Ltd., Yasunori Sato Speakers bureau: Eisai Co., Ltd.

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
Ultrafast electronic-phase change in solids by light, called photoinduced phase transition, is a central issue in the field of non-equilibrium quantum physics, which has been developed very recently. In most of those phenomena, charge or spin orders in an original phase are melted by photocarrier generations, while an ordered state is usually difficult to be created from a non-ordered state by a photoexcitation. Here, we demonstrate that a strong terahertz electric-field pulse changes a Mott insulator of an organic molecular compound in κ-(ET)2Cu[N(CN)2]Cl (ET = bis(ethylenedithio)tetrathiafulvalene), to a macroscopically polarized charge-order state; herein, electronic ferroelectricity is induced by the collective intermolecular charge transfers in each dimer. In contrast, in an isostructural compound, κ-(ET)2Cu2(CN)3, which shows the spin-liquid state at low temperatures, a similar polar charge order is not stabilized by the same terahertz pulse. From the comparative studies of terahertz-field-induced second-harmonic-generation and reflectivity changes in the two compounds, we suggest the possibility that a coupling of charge and spin degrees of freedom would play important roles in the stabilization of polar charge order.

This study aimed to clarify the features and long-term trends of SCD in working generation from 2005 through 2016 in Japan, using a prospective, nationwide, population based out-of-hospital cardiac arrest (OHCA) registry.
Methods
We performed data analysis of the nation-wide registry in Japan who experienced OHCA during the 12 years. Working generation was defined as 20 to 69 years and we analyzed only definitive cardiogenic OHCA as an approximation of SCD.
Results
The number of definitive cardiogenic OHCA of working generation during the period was 66,214 and 31% of the events in whole population was working generation. Definitive cardiogenic OHCA in working generation in terms of both number and percentage of the population had been decreased from 6522 (0.07‰) in 2005 to 4910 (0.06‰) in 2016, bystander cardiopulmonary resuscitation (CPR) and usage of automated external defibrillator (AED) ratio increased from 32.7% in 2005 to 49.6% in 2016, and 0.3% in 2005 to 14.7% in 2016 respectively, and the survival rate after one-month improved year by year, from 12.8% in 2005 to 34.0% in 2016 (picture below). Among non-medical bystanders, CPR was most often performed by colleagues in this generation, while AED use rate by colleague was smaller, and the time from witness to initial defibrillation was significantly longer than by passerby. Good prognosis was observed in terms of one-month survival ratio and neurological outcome for those undergoing CPR by colleague and passerby compared with other bystanders. For 12 years, although the degree varies, all non-medical bystander had same tendency; bystander CPR and usage of AED ratio increased, and the survival rate after one-month and neurological outcome improved year by year.
Conclusions
Not only the number but the incidence of cardiogenic OHCA in working generation has been decreased in Japan. The positive prognosis of this generation may be related to CPR by colleagues.

Abstract
Abstract
Introduction
Several report showed the association between ambient air pollution including particular matter under 2.5um (PM2.5) and increasing rate of hospitalization for heart failure. However, these report analyzed mainly cross-sectional, epidemiological data, thus the reports regarding association between vulnerability to PM2.5 and specific populations in acute heart failure (AHF) were scarce.
Purpose
1. To analyze the association between air pollution and rate of hospitalization for AHF
2. To analyze whether the vulnerability to air pollution differ between specific populations in AHF. Methods
A case-cross over analysis was conducted to 4980 consecutive patients registered for multicenter acute heart failure registry in 2017 in our city Japan. This registry enrolled patients transferred to cardiovascular care unit (80 institutions) via emergency medical services across our city area. Logistic regression analysis were conducted to estimate percentage changes in the rate of acute heart failure hospitalization associated with per 1μg/m3 PM2.5 concentration increase. We also conducted subgroup analysis for patients stratified by age, gender, comorbidities, left ventricular ejection fraction, and clinical scenario.
Results
An increase in 1 μg/m3 PM2.5 concentration corresponded to 2.9% (95% CI 1.2–4.6%) increase in AHF hospitalization. Patients with age younger than 75, without prior heart failure hospitalization, without history of hypertension, without anemia, and with reduced ejection fraction were more susceptible to increase in PM2.5 concentration (Figure).
Conclusions
Increase in PM2.5 concentration was associated with increased rate of AHF hospitalization. Effect of PM2.5 may differ across specific AHF subpopulations.

Abstract
Total of 261 samples of fish and environmental samples (i.e. wash water, swabs of hand/
gloves of workers, fish contact surfaces i.e. knives, cutting boards and working tables)
were collected from two Pangasius processing factories (PPF1 and PPF2). A total of
seventy-one (71) isolates of Escherichia coli were selected to study the prevalence of
antibiotics resistance using disk agar diffusion method. Overall, it was determined that
61% (22/36) of PPF1 isolates were resistant except to colistin while 68.57% (24/35) of
PPF2 isolates were resistant except kanamycin. High resistance was against ampicillin in
both PPF1 and PPF2 isolates (47.22% and 42.86%), followed by cefotaxime (33.33% and
40%) respectively. Varying resistance response to all other tested antibiotics such as
streptomycin, meropenem, tetracycline, sulfamethoxazole/trimethoprim and nalidixic acid
was also observed among the E. coli isolates from both factories. About 50% of the multidrug resistant (3-9 antibiotics) among PPF1 were observed whereas there were 45.83%
multi-drug resistant (3-7 antibiotics) among PPF2 isolates. The result from this study
reflected that there was a prevalence of multi-drug resistance of E. coli isolated during the
processing of Pangasius at the studied factories. Therefore, there is a need for an effective
risk management assessment models and management plans from stakeholders involved in
the Pangasius value chain (i.e. farmers, processors and government) to ensure the food
safety of production chain

Abstract
AIMS To study the mechanism of the antibacterial action of tea polyphenols such as catechins and theaflavins against Bacillus coagulans, and the interaction of epigallocatechin gallate (EGCg) or theaflavin 3,3'-di-O-gallate (TFDG) with the surface of B. coagulans cells was investigated. METHODS AND RESULTS The antibacterial activities of EGCg and TFDG against B. coagulans cells were measured by counting of the viable cells after the mixing with each polyphenol. Bactericidal effect of TFDG was shown at the concentration of greater than or equal to 62·5 mg l-1 ; however, at the same concentration, EGCg did not. According to the results of two dimensional (2D)-electrophoresis analysis, TFDG seemed to interact with cytoplasmic membrane proteins. The activity of the glucose transporters of the cells decreased 40% following the treatment with TFDG of 62·5 mg l-1 ; however, this decrease was only slight in case of EGCg. This result was in accordance with the strength of their bactericidal activities. CONCLUSION Our results suggest that the direct interaction between membrane proteins and TFDG is an important factor in the antibacterial activity of polymerized catechins, affecting their functions and leading to cell death. SIGNIFICANCE AND IMPACT OF THE STUDY Tea polyphenols can effectively use the prevention of product spoilage in the food and beverage industry.

Abstract
Experimental evidence exists that the Ξ-nucleus interaction is attractive. We search for NNΞ and NNNΞ bound systems on the basis of the AV8 NN potential combined with either a phenomenological Nijmegen ΞN potential or a first principles HAL QCD ΞN potential. The binding energies of the three-body and four-body systems (below the d+Ξ and ^{3}H/^{3}He+Ξ thresholds, respectively) are calculated by a high precision variational approach, the Gaussian expansion method. Although the two ΞN potentials have significantly different isospin (T) and spin (S) dependence, the NNNΞ system with quantum numbers (T=0, J^{π}=1^{+}) appears to be bound (one deep for Nijmegen and one shallow for HAL QCD) below the ^{3}H/^{3}He+Ξ threshold. Experimental implications for such a state are discussed.

Abstract
The concept of topology has been widely applied in condensed matter physics, leading to the identification of peculiar electronic states on three-dimensional (3D) surfaces or 2D lines separating topologically distinctive regions. In the systems explored so far, the topological boundaries are built-in walls; thus, their motional degrees of freedom, which potentially bring about new paradigms, have been experimentally inaccessible. Here, working with a quasi-1D organic material with a charge-transfer instability, we show that mobile neutral-ionic (dielectric-ferroelectric) domain boundaries with topological charges carry strongly 1D-confined and anomalously large electrical conduction with an energy gap much smaller than the one-particle excitation gap. This consequence is further supported by nuclear magnetic resonance detection of spin solitons, which are required for steady current of topological charges. The present observation of topological charge transport may open a new channel for broad charge transport-related phenomena such as thermoelectric effects.

Abstract
Abstract
Background
The prognosis of cancer patients has been improved partly because of the progress in cancer therapy, which increases the cancer survivors in the society. It may raise a concern regarding the development of heart failure (HF), because the anticancer agents have some serious side effects on cardiovascular system, especially in the aging society including Japan. However, the epidemiological data for the risk of HF in the cancer survivors is limited due to the lack of comprehensive dataset in the aging society. In this regard, the electronic health record (EHR), a big data, from the National Health Insurance in Japan provides a unique opportunity to obtain the suitable dataset.
Purpose
The purpose of this study was to clarify the prevalence and the risk factors of HF in cancer survivors, focusing on the impact of their age, using EHR in Japan.
Methods
We examined the EHR of 17.8 million patients, covering 14% of the total Japanese population. The EHR includes the diagnoses as coded with International Classification of Diseases, 10th revision (ICD-10), and the information for therapeutics. We extracted 159,380 patients who received anticancer agents between April 2008 to January 2017. HF patients were identified accordingto ICD-10 codes and the record for the use of therapeutic drugs for HF at least once after the HF diagnosis following the treatment with anticancer agents. We excluded the patients if they had other conditions indistinguishable from HF or if they had past history of HF before receiving anticancer agents.
Results
The mean follow-up period was 1.75 years and mean age (standard deviation) was 68.9 (11.6) years. The population over 75 years old were 37%, while males were 59.5%. There were prostate cancer (28.1%), lung cancer (13.4%), and colon cancer (12.6%)in males, and breast cancer (42.8%), colon cancer (11.5%), and lung cancer (8.6%)in females. Among them, 5,529 patients were diagnosed with HF, corresponding to the prevalence of 3.8%. The mean time form the initiation of chemotherapy to the HF onset was 1.03 year. In the Cox's proportional hazard model after the adjustments for comorbidity, HF was more prevalent in males with hazard ratio (HR) 1.07 and 95% C.I. 1.01–1.13 (p<0.05) and in those with obesity (HR 1.18, 95% C.I. 1.09–1.26, p<0.01).We divided the subjects into three age groups (younger; <65 years, intermediate; 65–74 years, older; ≥75 years). HF was more prevalent in older group than younger group (HR 1.72, 95% C.I. 1.60–1.85, p<0.01). Among the anticancer agents, doxorubicin showed HR 2.09 (95% C.I. 1.89–2.3, p<0.01), and trastuzumab showed HR 1.47 (95% C.I 1.25–1.73, p<0.01).
Conclusion
We showed that the average prevalence of HF after anticancer agentwas 3.8%. The independent risk factors for HF were older age, male, obesity, and the use of doxorubicin or trastuzumab. This study also demonstrated the usefulness of EHR in Japan, to investigate the cardiovascular risk associated with the anticancer agents.

Abstract
Abstract
Background
Despite recommendations from clinical practice guidelines, there is scant evidence confirming the effects of vasodilators on clinical outcomes in patients with acute heart failure (AHF).
Purpose
We sought to investigate the effects of intravenous vasodilators on clinical outcomes and to identify the potential patient populations that would benefit from its use.
Methods
Data of 26 212 consecutive patients urgently hospitalized for AHF between 2009 and 2015 were extracted from a multicenter data registration system (Tokyo Cardiovascular Care Unit Network Database, including 72 institutions within the Tokyo metropolitan area in Japan). Patients who did not present with typical AHF episodes, including those without pulmonary congestion on physical and/or chest X-ray and serum B-type natriuretic peptide level <500 pg/ml, as well as those who had hypotension and/or hypoperfusion (systolic blood pressure [SBP] <100 mmHg) as dominant presentation, were excluded. Propensity scores were calculated with multiple imputation and 1:1 matching performed between patients with and without vasodilators. The primary endpoint was in-hospital mortality and the secondary endpoints were length of intensive/cardiovascular care unit (ICU/CCU) stay and hospital stay.
Results
Overall, 8 863 patients were included in the present analysis; they were predominantly male (57%) with a median age of 79 (interquartile range: 70–86) years. Compared with the group without vasodilator use, the vasodilator group had higher SBPs and heart rates and higher frequency of assisted ventilation use, but lower frequency of intravenous diuretics use. After propensity score matching, there were no significant differences in in-hospital mortality rates (7.8% vs. 8.9% in patients without vasodilators, p=0.16) or in length of ICU/CCU stay (5.8 days vs. 5.4 days, p=0.44) and hospital stay (22.7 days vs. 23.8 days, p=0.22) between the groups. However, in subgroup analyses, favorable impacts of vasodilator use on in-hospital mortality were observed among patients who had higher SBPs and among those who had no atrial fibrillation upon admission (Figure). In addition, vasodilators were likely to be more effective in AHF patients with SBP increasing; while levels below 140 mmHg of SBP appeared to be associated with an increased risk for mortality among patients treated with vasodilators compared with those without vasodilators.

In patients with AHF, vasodilator use was not universally associated with improved in-hospital outcomes; however, its effect was dependent of individual clinical presentation. Detailed phenotyping might aid tailoring of treatment strategies for patients with AHF.

Abstract
Abstract
Introduction
Novel urinary biomarkers such as urinary neutrophil gelatinase-associated lipocalin (u-NGAL),urinary kidney injury molecule-1 (u-KIM-1), and urinary liver-type fatty acid-binding protein (uL-FABP) are proposed to be reliable markers for acute heart failure (AHF). Acute pulmonary edema (APE) is one of the vascular phenotypes of AHF, such as `vascular failure”, often with high blood pressure at admission. We aimed to investigate the differences in the clinical impact and prognostic utility of urinary biomarkers in AHF patients with and without APE.
Methods and results
This prospective observational study included 203 AHF patients (mean age: 77 years, 52% male). uL-FABP, u-NGAL, and u-KIM-1 were measured at admission and before discharge, with correction for urinary creatinine. APE was defined as acute-onset dyspnea and radiographic alveolar edema requiring non-invasive positive pressure ventilation. The primary outcome was a composite of all-cause death and AHF rehospitalization for 1 year. The median uL-FABP levels at admission were higher in APE (n=42) than in non-APE patients (n=161; 10.8 [4.5–23.7] vs. 20.7 [5.9–63.5] μg/gCr, p=0.017), whereas u-KIM-1, u-NGAL, and serum creatinine did not significantly differ between AHF patients with and without APE. The primary outcome did not differ between patients with and without APE. However, among patients with APE, Kaplan–Meier analysis showed that higher uL-FABP (≥median: 20.7 μg/gCr) was associated with adverse events (log-rank: p=0.019). After adjusting for age, sex, serum creatinine, and brain natriuretic peptide, multivariable Cox hazard analysis showed that higher uL-FABP is an independent predictor of adverse events (HR: 4.0 [1.2–18.2], p=0.023).
Conclusion
Unlike u-NGAL and u-KIM-1, uL-FABP was higher in APE patients than in non-APE patients. Further, among patients with APE, higher uL-FABP was predictive for poor prognosis.

Abstract
Patients receiving cancer chemotherapy may experience a number of potentially severe adverse drug reactions. It is crucial for all members of the health care team to monitor the effect of medicines on the patient to ensure the safety and efficacy of the chemotherapy. The present study prepared medication instruction sheets (MISs) on hematological malignancy and conducted a questionnaire survey to verify their usefulness among physicians, dentists, and nurses. MISs were prepared for 103 chemotherapy and 44 pretreatment regimens for hematopoietic stem cell transplantation in the Department of Hematology at Kyushu University Hospital. Eight questions were prepared to investigate whether MISs could help physicians, dentists, and nurses manage cancer chemotherapy more safely, effectively, and efficiently, as well as in the sharing of information. A total of 35 medical staff working in inpatient wards, including 8 physicians, 3 dentists, and 24 nurses, participated in the questionnaire survey. All of the staff responded to the questionnaire survey, which showed that the MISs were favorably accepted by the participants. There was no negative opinion on the management of chemotherapy using the MISs. The MIS was a useful tool for sharing information on cancer chemotherapy between patients and medical staff and for enabling efficient management, thereby improving the safety and efficacy of treatment.

Abstract
Coupling of charge and spin degrees of freedom is a critical feature of correlated electron oxides, as represented by the spin-related mechanism of a Cooper pair under high-T c superconductivity. A doublon-holon pair generated on an antiferromagnetic spin background is also predicted to attract each other via the spin-spin interaction J, similar to a Cooper pair, while its evidence is difficult to obtain experimentally. Here, we investigate such an excitonic effect by electroreflectance spectroscopy using terahertz electric field pulses in undoped cuprates: Nd2CuO4, Sr2CuO2Cl2, and La2CuO4. Analyses of the spectral changes of reflectivity under electric fields reveal that the splitting of odd-parity and even-parity excitons, a measure of doublon-holon binding energy, increases with J. This trend is reproduced by t-J-type model calculations, providing strong evidence of the spin-related doublon-holon pairing. Agreement with the calculations supports the s-wave symmetry of the doublon-holon pair in contrast to the d-wave Cooper pair in doped cuprates.

Abstract
UNLABELLED In this case-control study, we concluded that women with distal radial fractures who were surgically treated showed lower grip strength and dynamic body balancing than those of controls. These results suggest that measurements of grip strength and dynamic body balance may be useful screening tools to assess future fracture risk. INTRODUCTION Patients with distal radial fractures (DRFs) are at risk of future fragility fractures. However, their physical characteristics and tendencies for falls remain unclear. We aimed to compare the physical characteristics of women with and without distal radial fractures. METHODS We included 128 women with a DRF as their first fragility fracture (fracture group) who underwent surgical treatment. Concurrently, 128 age- and sex-matched participants without a history of fragility fractures were selected as controls (control group). The participants underwent assessments of grip strength and the body balancing ability test. Measurements were taken twice in the fracture group, at 2 weeks and 6 months postoperatively, and once in the control group. The body balancing ability test included the Functional Reach Test, Timed Up and Go test (TUG), 2-Step test (2ST), and Timed Uni-pedal Stance test. The participants also completed questionnaires about their health. RESULTS There were no significant differences (p > 0.05) in patient characteristics between the groups. The fracture group showed lower grip strength across all age groups. In the DRF group, prolonged TUG time was observed at 2 weeks postoperatively in all age groups and at 6 months in participants aged 55-74 years; the 2ST score was significantly lower in participants aged between 65 and 74 years. CONCLUSIONS Women with DRF demonstrated lower grip strength and dynamic body balancing ability. Lower grip strength and dynamic body balancing ability were identified as significant risk factors in women with DRF, suggesting that these may be useful screening tools to assess fracture risk.

Abstract
To assess compliance with the Japanese antiemetic guidelines for chemotherapy-induced nausea and vomiting (CINV), the frequencies of CINV occurrence and use of antiemetic rescue medications were examined in patients with hematological malignancy. A total of 40 patients with hematologic malignancy were eligible in this study. This study was performed in the Department of Hematology, Kyushu University Hospital, as a subgroup analysis from a nationwide, multicenter prospective cohort study conducted by the CINV Study Group of Japan. In the patients with hematological malignancy, the guideline compliance rate was 45 %. Five patients (22.7 %) experienced vomiting during the observation period after receiving non-guideline-consistent antiemetic prophylaxis, whereas no patient experienced vomiting after receiving guideline-consistent antiemetic prophylaxis. The study was not sufficiently powered to reach a statistical significance in its frequency of occurrence between the compliance and non-compliance groups. In the entire study period, 8 out of 40 patients required rescue medication, but there was no association between the status of compliance and the antiemetic guidelines. A total of 22 (55.0 %) patients achieved complete response, which was defined as no vomiting and no use of antiemetic rescue medication, during the study period. The rate of compliance with the prophylactic antiemetic treatment guidelines seemed to be low in patients with hematological malignancy, although the status of the guideline compliance did not always influence the antiemetic effects.

Abstract
Abstract
[Introduction] Surgery for breast cancer (BC) became less invasion, from radical mastectomy to modified or breast conserving surgery (BCS). Axillary lymph node (ALN) management for cN0 also became less, from ALN dissection (ALND) to sentinel lymph node (SLN) biopsy. In some cases, management without ALND is allowed even if ALN macro-metastasis exist.
[Background] ALND for SLN metastasis positive case is useful for local control, staging and decision making for post-operative treatment. Since the ACOSOG Z0011 trial (Z11) result was reported, however, the necessity of ALND, even if SLN metastasis, became less. In the NCCN guideline (NCCN), strongly influenced by Z11, for cN0 BC with SLN metastasis, operations without ALND are allowed in cases of T1 or T2, the number of metastatic ALN 1 or 2, BCS with whole breast radiation and no-neoadjuvant therapy. This does not mean ALND was abolished but the position of ALND changed, from the perspective that over invasive procedure must be prohibited with appropriate pre-operative and intra-operative diagnosis. If there are some discordance between clinical and pathological diagnosis of tumor size or ALN metastasis, however, the criteria for axillary operation by NCCN will not be recommended. We have major two types of invasive carcinoma, ductal (IDC) and lobular (ILC). Z11 or NCCN did not describe about these two phenotypes. We compared these at the point of suitable axillary management.
[Subjects] Out of 1320 invasive BC (IDC; 1212, ILC; 108) cases in our hospital from January 2008 to January 2018, 1210 cases (IDC; 1113, ILC; 97) with T1/T2 and cN0 were reviewed in two points, the judgment of the competence for BCS was appropriate or not, and cN0 reflected the condition for the omission of ALND (ALN metastasis within 2) or not.
[Results] The difference of diameter between cT and pT; dT (=pT-cT) were measured significantly larger in ILC (0.68±1.97cm) than IDC (0.01±1.08cm)(p<0.01, t-test) with the wide scattering. We can make proper evaluation for the cT of IDC, but underestimate for ILC. The conversion rate from cN0 to pN1 was significantly higher in ILC (33/97; 34.0%) than IDC (238/1113; 21.4%)(p<0.01, χ2 test). In addition, the cases with 3 or more ALN metastasis, this means ALND is necessary, was observed with significantly higher frequent in ILC (13/97; 13.4%) than IDC (74/1113; 7.1%)(p=0.02, χ2 test). Clinical evaluation for ALN in ILC was difficult and inaccurate.
[Discussion] Commonly, ILC makes diffuse spread into the breast tissue. This feature will make it difficult to evaluate the clinical appropriate tumor size. Because of not only underestimation but wide scattering, the diagnosis for safety BCS may not be guaranteed in ILC. For ALN, cN0 did not reflect adequately the condition of omission for ALND in ILC compared with IDC. ILC patients with SLN metastasis have to be performed ALND at higher risk. These facts will mean that ILC does not fit to ALN management according to NCCN. Few guidelines separate ILC from IDC for the axillary management. The validation of clinical trials for ALND should be done in histological subtype as well as intrinsic again. Clinically, we must observe carefully in cases of ILC without ALND according to Z11.

Abstract
A multiple-hydrogen-bond approach was applied to shorten Pt-X-Pt distances in Cl- and Br-bridged Pt chain complexes. [Pt(dabdOH)2Cl]Cl2 (5) and [Pt(dabdOH)2Br]Br2 (6) (dabdOH = (2 S,3 S)-2,3-diaminobutane-1,4-diol) contain hydroxy groups, which form additional hydrogen bonds with counteranions. 5 has the shortest Pt-Cl-Pt distance (5.0747(8) Å) of all Cl-bridged Pt chain complexes reported to date. Furthermore, the smallest optical gap (1.45 eV for 5 and 1.19 eV for 6) in any Cl- or Br-bridged Pt chain complex was achieved. 6 has the highest electrical conductivity (1.9 × 10-5 S cm-1 at room temperature) of all Br-bridged Pt chain complexes. This study shows that the introduction of additional hydrogen bonds between the ligands and halides is effective to enhance the electronic properties of halogen-bridged metal complexes.

Abstract
Topological defects have been explored in different fields ranging from condensed matter physics and particle physics to cosmology. In condensed matter, strong coupling between charge, spin, and lattice degrees of freedom brings about emergent excitations with topological characteristics at low energies. One-dimensional (1D) systems with degenerate dimerization patterns are typical stages for the generation of topological defects, dubbed "solitons"; for instance, charged solitons are responsible for high electrical conductivity in doped trans-polyacetylene. Here, we provide evidence based on a nuclear magnetic resonance (NMR) study for mobile spin solitons deconfined from a strongly charge-lattice-coupled spin-singlet ferroelectric order in a quasi-1D organic charge-transfer complex. The NMR spectral shift and relaxation rate associated with static and dynamic spin susceptibilities indicate that the ferroelectric order is violated by dilute solitonic spin excitations, which were further demonstrated to move diffusively by the frequency dependence of the relaxation rate. The traveling solitons revealed here may promise the emergence of anomalous electrical and thermal transport.

Abstract
A charge excitation in a two-dimensional Mott insulator is strongly coupled with the surrounding spins, which is observed as magnetic-polaron formations of doped carriers and a magnon sideband in the Mott-gap transition spectrum. However, the dynamics related to the spin sector are difficult to measure. Here, we show that pump-probe reflection spectroscopy with seven-femtosecond laser pulses can detect the optically induced spin dynamics in Nd2CuO4, a typical cuprate Mott insulator. The bleaching signal at the Mott-gap transition is enhanced at ~18 fs. This time constant is attributable to the spin-relaxation time during magnetic-polaron formation, which is characterized by the exchange interaction. More importantly, ultrafast coherent oscillations appear in the time evolution of the reflectivity changes, and their frequencies (1400-2700 cm-1) are equal to the probe energy measured from the Mott-gap transition peak. These oscillations can be interpreted as the interference between charge excitations with two magnons originating from charge-spin coupling.

Abstract
SummaryThe ability of platelets to synthesize thromboxane B2 (TxB2) from arachidonic acid (AA) or prostaglandin H2 (PGH2) was studied in 26 control subjects, 40 patients with essential hypertension, 20 patients with cerebrovascular disease (CVD) not taking aspirin and 11 patients with CVD taking aspirin. The activity of platelets to form TxB2 from AA or PGH2 was measured using 1 — 14C arachidonic acid or 1—14C PGH2 as a substrate. There was no significant difference in TxB2 generation from AA or PGH2 among the platelets collected from the control subjects, hypertensive patients and CVD patients not taking aspirin.In CVD patients taking aspirin, marked suppression was observed in TxB2 synthesis from AA, but no suppression in TxB2 synthesis from PGH2. At least 750 mg aspirin per day were required for nearly complete suppression of TxB2 generation from AA.
