Abstract
BACKGROUND This study evaluated the non-inferiority of dexamethasone (DEX) on day 1, with sparing on days 2-4 in cisplatin-based chemotherapy. METHODS Patients with malignant solid tumors who were treated with cisplatin (≥50 mg/m²) were randomly assigned (1:1) to receive either DEX on days 1-4 (Arm D4) or DEX on day 1 (Arm D1) plus palonosetron, NK-1 RA, and olanzapine (5 mg). The primary endpoint was complete response (CR) during the delayed (24-120 h) phase. The non-inferiority margin was set at -15%. RESULTS A total of 281 patients were enrolled, 278 of whom were randomly assigned to Arm D4 (n = 139) or Arm D1 (n = 139). In 274 patients were included in the efficacy analysis, the rates of delayed CR in Arms D4 and D1 were 79.7% and 75.0%, respectively (risk difference -4.1%; 95% CI -14.1%-6.0%, P = 0.023). However, patients in Arm D1 had significantly lower total control rates during the delayed and overall phases, and more frequent nausea and appetite loss. There were no significant between-arm differences in the quality of life. CONCLUSION DEX-sparing is an alternative option for patients receiving cisplatin; however, this revised administration schedule should be applied on an individual basis after a comprehensive evaluation.

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

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

Abstract
Chemotherapy-induced nausea and vomiting (CINV) is one of the most serious adverse effects of cancer therapy. Cancer patients frequently use acid suppressants (AS) for palliation of gastrointestinal symptoms associated with malignancy and/or anticancer therapy. AS are suggested as an additional option for CINV management in several antiemetic guidelines, although their efficacy remains unknown. The aim of this study was to determine whether AS administration affects CINV incidence in cisplatin and gemcitabine treatment for biliary tract cancer. The primary endpoint was to evaluate whether AS administration was associated with the incidence of all-grade nausea in the first administration by logistic analysis. The secondary endpoints were to assess factors associated with anorexia. Prophylactic antiemetics were based on current guidelines. Nausea occurred in 34.2% of patients (grade 1, 31.7%; grade 2, 2.5%). Patients exhibiting vomiting and anorexia represented 4.2% and 39.1%, respectively, without grade 3/4 symptoms. Multivariate analysis suggested that the independent risk factors for nausea as female sex, and no- or less-alcohol drinking habit and regular narcotics administration were associated with anorexia. In contrast, AS administration was not associated with nausea and anorexia incidence (odds ratio, 95% confidence interval: 1.43, 0.64-3.23; P =0.38 for nausea, 1.62, 0.71-3.68; P =0.25 for anorexia). In conclusion, we found that AS administration is not associated with CINV incidence, and female sex is a risk factor for nausea, and non-alcohol drinking habits and regular narcotic use are factors associated with anorexia in cisplatin and gemcitabine treatment for biliary tract cancer. We should correctly administer AS depending on the patient's situation. Successful CINV management needs effective monitoring and administration of prophylactic antiemetics and counter-measure medicines for patients at risk.

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

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

Abstract
Background
Prophylactic use of implantable cardioverter-defibrillators (ICDs) to prevent sudden cardiac death (SCD) is widely spread all over the world in patients with hypertrophic cardiomyopathy (HCM). Apical HCM is a phenotype variant of HCM, with hypertrophy predominantly affecting apex, that was initially described 30 years ago. Apical HCM patients may have different clinical prognosis compared with other subsets of HCM. In previous studies, apical HCM patients seem to have a more benign prognosis than other types of HCM.

Objective
The aim of this study is to identify the difference between the prognosis of apical and the other HCM patients with an ICD.
Methods
We retrospectively analyzed the database of our ICD clinic. All subjects had been implanted with an ICD from October 2006 to August 2017. We classified HCM patients into LV outflow tract obstruction (LVOTO) and midventricular obstruction (MVO), apical HCM and other non-obstructive types. We divided all the patients into apical and other types of HCM, and examined their background, incidence of appropriate ICD therapies, hospitalization for heart failure, electrical storm and death.

A total of consecutive 62 Japanese HCM patients with an ICD (follow-up period, 86±25 months; age, 67±14 years; male sex, 85%; left ventricular ejection fraction, 57±12%; LV max wall-thickness, 19±5mm; LV apical aneurysm, 9.7%; HCM Risk-SCD, 4.4±3.0) were enrolled in this study. We classified them into 14 apical HCM and 48 other types of HCM patients. The clinical characteristics and major events of these patients are shown in the Figure. During the follow-up periods, there were no significant differences in the incidence of hospitalization for heart failure, electrical storm and death between the 2 groups (p=0.40; p=0.22; p=0.23). Appropriate therapies occurred in 5 of 14 (36%) patients with apical HCM and 4 of 48 (8.3%) patients with other types of HCM (p=0.022).
Conclusions
Appropriate ICD therapy was more prevalent in patients with apical HCM, compared to patients with other types of HCM. However, the incidences of hospitalization for heart failure, electrical storm and death were not significantly different between two groups.

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

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

Abstract
BACKGROUND This randomized study was designed to evaluate the clinical effect of an elemental diet during chemotherapy in patients with esophageal cancer. METHODS The inclusion criteria were as follows: (1) esophageal squamous cell carcinoma, (2) stage IB-IV, (3) schedule to receive docetaxel, cisplatin, and 5-fluorouracil (DCF chemotherapy), (4) 20-80 years old, (5) performance status of 0-2, (6) oral intake ability, and (7) written informed consent. Patients were divided into two groups: the elemental supplementary group and the non-supplementary group. Patients received ELENTAL® (160 g/day) orally 9 weeks after the start of chemotherapy. Primary endpoint was the incidence of grade 2 or higher gastrointestinal toxicity according to the Common Terminology Criteria for Adverse Events, version 4.0. Secondary endpoints were the incidence of all adverse events and the evaluation of nutritional status. RESULTS Thirty-six patients in the elemental supplementary group and 35 patients in the non-supplementary group were included in the analysis. The incidence of grade 2 or higher gastrointestinal toxicity and all grade 3 or 4 adverse events did not differ significantly between the groups. In the elemental supplementary group, the body weight (p = 0.057), muscle mass (p = 0.056), and blood levels of transferrin (p = 0.009), total amino acids (p = 0.019), and essential amino acids (p = 0.006) tended to be maintained after chemotherapy. CONCLUSION Nutritional support provided by an amino acid-rich elemental diet was ineffective for reducing the incidence of adverse events caused by DCF chemotherapy in patients with esophageal cancer.

Abstract
BACKGROUND An exploratory study was designed to evaluate the efficacy of granulocyte colony stimulating factor support for chemotherapy consisting of docetaxel, cisplatin and 5-fluorouracil chemotherapy in patients with oesophageal cancer. METHODS The inclusion criteria were as follows: (1) oesophageal squamous cell carcinoma, (2) a schedule to receive three courses of induction chemotherapy (docetaxel 75 mg/m2 day 1, cisplatin 75 mg/m2 day 1, 5-fluorouracil 750 mg/m2 days 1-5, every 3 weeks), (3) stage IB-III, (4) 20-75 years old, (5) 0-1 performance status, (6) preserved organ functions and (7) written informed consent. The endpoints were to evaluate the efficacy of granulocyte colony stimulating factor support including secondary prophylactic usage for docetaxel, cisplatin and 5-fluorouracil chemotherapy. Patients who previously had 'febrile neutropenia', or 'Grade 3 or 4 infection accompanied by grade 3 or 4 neutropenia' prophylactically received granulocyte colony stimulating factor support from day 7. RESULTS A total of 91 patients were included in the analysis. Granulocyte colony stimulating factor support was given to 81.3%. The incidence of grade 4 neutropenia and febrile neutropenia were 81.3 and 32.9%, respectively. The dose of anticancer agents was reduced in 48.4%. There were no treatment-related deaths. The relative dose intensity of docetaxel, cisplatin and 5-fluorouracil were 92.7 ± 9.8%, 86.0 ± 15.6% and 91.8 ± 10.0%, respectively. In the secondary prophylactic granulocyte colony stimulating factor support group, the neutrophil count significantly increased between day 7 and day 13 as compared with the non-prophylactic granulocyte colony stimulating factor support group (P < 0.05 for each day). CONCLUSIONS Granulocyte colony stimulating factor support including secondary prophylactic usage may be feasible for maintaining the intensity of docetaxel, cisplatin and 5-fluorouracil chemotherapy in patients with oesophageal cancer.

Abstract
INTRODUCTION Dexamethasone (DEX) is administered for multiple days to prevent chemotherapy-induced nausea and vomiting for patients receiving highly emetogenic chemotherapy (HEC); however, its notorious side effects have been widely reported. Although our multicentre randomised double-blind comparative study verified non-inferiority of sparing DEX after day 2 of chemotherapy when combined with neurokinin-1 receptor antagonist (NK1-RA) and palonosetron (Palo) for patients receiving HEC regimen, DEX sparing was not non-inferior in patients receiving cisplatin (CDDP)-based HEC regimens in subgroup analysis. Recently, the efficacy of the addition of olanzapine (OLZ) to standard triple antiemetic therapy on HEC has been demonstrated by several phase III trials. This study aims to confirm non-inferiority of DEX sparing when it is combined with NK-1RA, Palo and OLZ in patients receiving CDDP-based HEC regimens. METHODS AND ANALYSIS This is a randomised, double-blind, phase III trial. Patients who are scheduled to receive CDDP ≥50 mg/m2 as initial chemotherapy are eligible. Patients are randomly assigned to receive either DEX on days 1-4 or DEX on day 1 combined with NK1-RA, Palo and OLZ (5 mg). The primary endpoint is complete response (CR) rate, defined as no emesis and no rescue medications during the delayed phase (24-120 hours post-CDDP administration). The non-inferiority margin is set at -15.0%. We assume that CR rates would be 75% in both arms. Two hundred and sixty-two patients are required for at least 80% power to confirm non-inferiority at a one-sided significance level of 2.5%. After considering the possibility of attrition, we set our final required sample size of 280. ETHICS AND DISSEMINATION The institutional review board approved the study protocol at each of the participating centres. The trial result will be presented at international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER UMIN000032269.

Abstract
Background:Oral Janus kinase inhibitors (JAKi) have dramatically altered outcomes in patients with rheumatoid arthritis (RA). However, there remains some proportion of patients who respond to inadequately JAKi treatment (JAKi-IR) [1,2]. The characteristics in RA patients associated with JAKi-IR have not been fully demonstrated.Objectives:To clarify the characteristics of JAKi-IR in patients with RA by cluster analysis.Methods:This retrospective study comprised 120 RA patients who were treated with JAKi (Tofacitinib or Baricitinib) between July 2013 and September 2019 in five facilities. The disease status at the baseline, at 12 weeks after JAKi treatment and at the time point of withdrawing JAKi was assessed using the Disease Activity Score (DAS28) and the American College of Rheumatology (ACR) response criteria. JAKi-IR was defined as follows, primary non-response at 12 weeks after JAKi treatment: withdrawal of JAKi with ACR20 non-response or non-improvement in DAS28-CRP (ΔDAS28-CRP<1.2 from baseline), secondary non-response: withdrawal of JAKi without clinical remission after 12 weeks. Hierarchical cluster analysis was performed with the following variables: gender, age, disease duration, bone erosion, ACR functional classification (Class ≥3), comcomitant rheumatoid arthritis related interstitial lung disease (RA-ILD) or other autoimmune disease (AID), anti-citrullinated protein antibody (ACPA) positivity, rheumatoid factor (RF) at baseline, use/dose of methotrexate (MTX) and prednisolone (PSL), serum ESR/CRP, tender/swollen joint counts (TJC/SJC), visual analog scale by patients (VAS-Pt), and prior of biologic DMARDs.Results:The 120 enrolled patients were classified into 4 groups by cluster analysis(Figure1), The characteristics of each group are as follows, Group A(n=21): female + bone erosion + RF/ACPA positive + AID + MTX non-user, Group B(n=36): male + older age + RA-ILD + RF/ACPA positive + MTX non-user, Group C(n=35): RF/ACPA positive + absence of RA-ILD + MTX user, Group D (n=28): seronegative + MTX user + absence of RA-ILD + history of biologic DMARDs failure. The rate of JAKi-IR was A:9%, B:8%, C:20%, D:32%, and the significant difference between Group B and D was identified (p=0.02). In multiple comparison of 4 groups, no significant difference was identified (p=0.06) (Figure2).Conclusion:JAKi-IR would be more likely to be seronegative, MTX use, absence of RA-ILD and history of biologic DMARDs failure.

Abstract
An in vitro-produced bovine embryo has a low conception rate compared with that of an in vivo embryo. The present study was conducted to examine the effects of different treatments delivered to donors before ovum pickup (OPU) sessions to improve the conception rate of in vitro-produced bovine embryos. In total, 351 OPU sessions were performed on 138 Holstein and 213 Japanese Black cows from January to December 2017. Donors were divided into 4 groups based on their pretreatment before OPU: (1) single injection of 2.5 AU of FSH 40h before OPU; (2) CIDR insertion on Day 0, injection of 2mg of oestradiol benzoate on Day 1, 4 injections of FSH (each 2.5 AU) every 12h beginning from Day 5 to 7, followed by removal of CIDR and OPU on Day 9; (3) injection of 50μg of gonadotropin-releasing hormone 72h before OPU; or (4) no pretreatment. The collected cumulus-oocyte complexes were matured for 22h in 25mM of HEPES buffered TCM-199 supplemented with 5% newborn calf serum and 0.02 AU mL−1 FSH. After 6h of gamete co-culture (5.0×106 sperm mL−1), the presumptive zygotes were washed and the remaining cumulus cells were denuded by pipetting. The presumptive zygotes were then cultured in KSOMaa supplemented with 5% newborn calf serum for 9 days in a micro-well culture dish (Dai Nippon Printing, Tokyo, Japan). Blastocyst formation rates were analysed 9 days after insemination, and the formed blastocysts were transferred to oestrous synchronized recipients on the seventh or eighth day after oestrus. The data were analysed by Chi-squared test with Yates correction. The average numbers of collected oocytes were 57.7±17.4 (n=136), 25.3±12.8 (n=20), 28.8±12.5 (n=18) and 24.3±12.9 (n=177) in groups 1 to 4, respectively. Groups 1 and 2 showed significantly (P<0.01) high percentages of Grade-1 oocytes (52.1 and 49.6%, respectively) compared with groups 3 and 4 (37.3 and 39.9%, respectively). The proportion of blastocysts in groups 1 (38.6%) was significantly different compared with that in groups 2 (32.1%) and 4 (35.3%), but the difference was insignificant in the case of group 3 (36.4%). The conception rates in groups 1 (43.5%, n=868) and 2 (59.1%, n=44) were significantly (P<0.05) higher than those in groups 3 (35.1%, n=57) and 4 (34.9%, n=768). These results suggest that although the efficiency of embryo production did not differ largely between donors pretreated with 4 FSH injections and those without any pretreatment, the conception rate in donors pretreated with 4 FSH injections was significantly higher than that in donors without pretreatment. Moreover, donors pretreated with a single injection of FSH showed significantly high efficiency of embryo production and conception rate than donors without pretreatment.

Abstract
OBJECTIVE Curative synchronous double primary cancers of the head and neck and the esophagus (CSC-HE) are frequently detected, but a standard treatment remains to be established. We studied the clinical course to explore appropriate treatment strategies. METHODS We retrospectively studied consecutive 33 patients who had CSC-HE. The disease stage was classified into 4 groups: group A, early head and neck cancer (HNC) and early esophageal cancer (EC); group B, early HNC and advanced EC; group C, advanced HNC and early EC; and group D, advanced HNC and advanced EC. As induction chemotherapy, the patients received 3 courses of TPF therapy (docetaxel 75mg/m2 on day 1, cisplatin 75mg/m2 on day 1, and 5-fluorouracil 750mg/m2 on days 1-5) at 3-week intervals. The clinical courses and treatment outcomes were studied according to the disease stage of CSC-HE. RESULTS The disease stage of CSC-HE was group A in 1 patient (3%), group B in 9 patients (27.3%), group C in 3 patients (9.1%), and group D in 20 patients (60.6%). The median follow-up was 26months, and the 2-year overall survival rate was 67.4%. In groups A, B, and C, the 2-year overall survival rate was 83.3%. In group D, the 2-year overall survival rate was 62.6%. Ten of 20 patients in group D received induction chemotherapy with TPF, and 6 patients were alive and disease free at the time of this writing. CONCLUSION The treatment outcomes of patients with CSC-HE were relatively good. TPF induction chemotherapy might be an effective treatment for patients with advanced HNC and advanced EC.

Abstract
Leukocyte kinesis in the capillary vascular bed during hemodialysis (HD) was investigated to elucidate the mechanism of transient leukopenia. Leukocyte movement was observed microscopically during HD using the rabbit ear chamber (REC) technique, which permits visualization of the movement of blood corpuscles in capillaries. Blood was drawn from the femoral artery and returned into the auricular and/or carotid artery so that the blood passing through the hollow fiber artificial kidney (HFAK) flowed into capillaries in the REC. Leukocyte counts of blood samples taken from the afferent and efferent limbs of the HD circuit, the right jugular vein and the right atrium were determined consecutively during HD. The difference in the leukocyte count was observed between the afferent and efferent limbs for the first 15 minutes and thereafter between the efferent limb and the jugular vein. The “transpulmonary” difference in the leukocyte count was not noticed throughout HD. Between 15 and 90 minutes after the start of HD, scarcely any circulating leukocytes were found in capillaries in the REC and some leukocytes were attached to the endothelial surface. Thereafter circulating leukocytes were seen again and detachment of leukocytes from the endothelial surface was observed. No leukocyte aggregation or embolization of aggregating leukocytes was noticed. This evidence suggests that leukopenia may be attributed to the transient shift of leukocytes to the marginal pool of the vessel lumen and this process may not be specific for the pulmonary vasculature, but may occur in the first capillary bed into which the blood passing through the HFAK flows. The attachment of leukocytes to the surface membrane of the HFAK may contribute to the transient leukopenia especially during the initial period of the HD.

Abstract
The conventional superovulation treatment using follicle-stimulating hormone (FSH) comprises 2 intramuscular injections per day for 3 to 4 days. This conventional method requires frequent handling of donors—which may cause increasing stress in donors—and high labour costs. Therefore, to alleviate these issues, a treatment protocol using a single FSH injection under on-farm conditions is needed. The objective of this study was to evaluate the feasibility of the single subcutaneous FSH injection protocol (Sugawara et al. 2017 Reprod. Fertil. Dev. 29, 209), compared with with the traditional twice-daily intramuscular FSH injection protocol, in Japanese Black cows. Japanese Black cows (n = 13) were superovulated using 2 treatments in a crossover design. All cows received an intravaginal progesterone device (CIDR) at random stages of the oestrous cycle (Day 0), and 2 mg of oestradiol benzoate on Day 1 (24 h after CIDR insertion). On Day 6, for the group receiving a single subcutaneous FSH injection (single-FSH), 20 armor units (AU) of pFSH dissolved in 30 mL of saline was subcutaneously injected in the neck region and 0.5 mg of prostaglandin F2α was intramuscularly injected simultaneously. For the control group, FSH administration was initiated at Day 6. A total dose of 20 AU of FSH was administered in 3 days (with decreasing doses of 5, 3, and 2 AU, respectively, per injection) with 2 intramuscular injections per day; 0.5 mg of prostaglandin F2α was injected 48 h after the first FSH injection. For both groups, CIDR was removed 60 h after FSH injection and AI was done 42 to 48 h after CIDR removal. Embryo collections were performed 7 days after AI. Data were analysed using t-test for the mean numbers of collected ova/embryos and transferable embryos, and chi-squared test for the proportion of transferable embryos. There were no significant differences in the mean numbers (single-FSH v. control) of ova/embryos collected (17.1 ± 12.1 v. 17.8 ± 9.3), or transferable embryos (8.4 ± 9.3 v. 10.3 ± 8.7), and proportion of transferable embryos (45.0 ± 34.0 v. 56.6 ± 36.5). These results showed that although a slightly higher number and proportion of transferable embryos were obtained in the control group, a superovulation treatment protocol involving a single subcutaneous FSH injection can be effectively used for Japanese Black cows, under on-farm conditions.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) has become prevalent in esophageal squamous cell carcinoma (ESCC), but its long-term prognostic advantages remain unclear. The latest prognostic outcomes in clinical Stage (cStage) II/III ESCC with NAC were herein elucidated. PATIENTS AND METHODS NAC prior to curative treatment was done in 115 cStage II/III ESCC patients with either cisplatin (CDDP)/5-fluorouracil (5-FU; CF) (n = 41) or docetaxel/CDDP/5-FU (DCF) NAC (n = 74) between 2007 and 2013. RESULTS (1) Esophagectomy was finally performed in 35 of the 41 CF NAC cases and in 48 of the 74 DCF NAC cases. The preservation rate of the esophagus was higher in the DCF NAC than in the CF NAC (p = 0.018). (2) The overall survival was better in DCF NAC than in CF NAC (p = 0.071), and progression-free survivals were 58.3% with DCF and 30.5% with CF (p = 0.0060). DCF NAC was associated with fewer cases of progression than CF NAC (p = 0.0040), largely due to excellent control of the preoperative disease (p = 0.018) and postoperative lymph node recurrence (p = 0.014). CONCLUSION DCF NAC in cStage II/III ESCC could have a great potential to achieve a better prognosis due to suppression of specific progression events with a higher preservation rate of the esophagus.

Abstract
Superovulation treatment using FSH requires injection twice a day, for 3 to 4 days. This conventional method requires frequent handling of donors and higher labour costs. Therefore, simplification of the superovulation treatment protocol is needed to reduce animal handling and labour costs. The objective of this study was to investigate the effect of a single subcutaneous FSH injection and the timing of prostaglandin F2α (PGF; cloprostenol) administration on the superovulatory response in Japanese Black cows (Hiraizumi et al. 2015 Theriogenology 83, 466–473) and to determine whether the superovulation treatment protocol can be used in on-farm conditions. A total of 270 Japanese Black cows were used in this study. Twenty Armour units of pFSH dissolved in 30 mL of saline was injected subcutaneously in the neck region. In Experiment 1, 32 cows received an intravaginal progesterone device (CIDR) at random stages of the oestrous cycle (Day 0), and 2 mg of oestradiol benzoate on Day 1 (24 h after CIDR insertion). On Day 6, FSH was injected subcutaneously, and 16 cows were simultaneously injected with 0.5 mg of PGF (0-h PGF, Group A); the other 16 cows were injected with 0.5 mg of PGF at 48 h (on Day 8) after FSH injection (48-h PGF, Group B). The CIDR was removed at 60 h after FSH injection and AI was done 42 to 48 h after CIDR removal. Embryo collections were performed 7 days after AI. In Experiment 2, 238 cows were used in farm conditions. The cows were superstimulated using the same protocol as that used for Group A. Data were analysed by ANOVA for the mean numbers of collected ova/embryos and transferrable embryos and chi-square test for the proportion of transferrable embryos. In Experiment 1, there were no differences in the mean numbers of ova/embryos collected (16.9 ± 12.3 v. 16.1 ± 17.1) or transferrable embryos (11.1 ± 9.5 v. 7.2 ± 6.2). However, the proportion of transferrable embryos for Group A was significantly higher than that of Group B (65.9 v. 44.7%; P < 0.01). In Experiment 2, the mean numbers of ova/embryos collected and transferrable embryos were 15.7 ± 13.3 and 6.8 ± 7.8, respectively. These results showed that a superovulation treatment protocol involving a single subcutaneous injection of FSH with simultaneous PGF injection can be effectively used for Japanese Black cows under on-farm conditions.

Abstract
BACKGROUND Evaluation of the contractile state of the left ventricle during exercise is important in drawing up a protocol of cardiac rehabilitation. It has been demonstrated that color Doppler- and echo tracking-derived carotid arterial wave intensity is a sensitive index of global left ventricular (LV) contractility. OBJECTIVES We assessed the feasibility of measuring carotid arterial wave intensity and determining force-frequency (contractility-heart rate) relationships (FFR's) during exercise totally noninvasively. METHODS We measured carotid arterial wave intensity with a combined color Doppler and echo tracking system in 15 healthy young male volunteers (age 20.8 ± 1.3 years) at rest and during exercise. FFR's were constructed by plotting the maximum value of wave intensity (WD1) against heart rate (HR). RESULTS WD1 increased linearly with an increase in HR. The goodness-of-fit of the regression line of WD1 on HR in each subject was very high (r2 0.67 ~ 0.91, p < 0.0001 respectively). The slope of the WD1-HR relation ranged from 0.31 to 1.52 [m/s(3)(beat/min)]. CONCLUSIONS A global LV FFR can be generated in healthy young volunteers with an entirely noninvasive combination of exercise and wave intensity. These data should show the potential usefulness of FFR in the context of cardiac rehabilitation.

Abstract
OBJECTIVES The objective of this study was to compare the sensitivity of detection of lung nodules on low-dose screening CT images between radiologists and technologists. METHODS 11 radiologists and 10 technologists read the low-dose screening CT images of 78 subjects. On images with a slice thickness of 5 mm, there were 60 lung nodules that were ≥5 mm in diameter: 26 nodules with pure ground-glass opacity (GGO), 7 nodules with mixed ground-glass opacity (GGO with a solid component) and 27 solid nodules. On images with a slice thickness of 2 mm, 69 lung nodules were ≥5 mm in diameter: 35 pure GGOs, 7 mixed GGOs and 27 solid nodules. The 21 observers read screening CT images of 5-mm slice thickness at first; then, 6 months later, they read screening CT images of 2-mm slice thickness from the 78 subjects. RESULTS The differences in the mean sensitivities of detection of the pure GGOs, mixed GGOs and solid nodules between radiologists and technologists were not statistically significant, except for the case of solid nodules; the p-values of the differences for pure GGOs, mixed GGOs and solid nodules on the CT images with 5-mm slice thickness were 0.095, 0.461 and 0.005, respectively, and the corresponding p-values on CT images of 2-mm slice thickness were 0.971, 0.722 and 0.0037, respectively. CONCLUSION Well-trained technologists may contribute to the detection of pure and mixed GGOs ≥5 mm in diameter on low-dose screening CT images.

Abstract
AIMS The objective of this study was to examine transcriptional changes in Escherichia coli when the bacterium was growing in the lettuce rhizoshpere. METHODS AND RESULTS A combination of microarray analyses, colonization assays and confocal microscopy was used to gain a more complete understanding of bacterial genes involved in the colonization and growth of E. coli K12 in the lettuce root rhizosphere using a novel hydroponic assay system. After 3 days of interaction with lettuce roots, E. coli genes involved in protein synthesis, stress responses and attachment were up-regulated. Mutants in curli production (crl, csgA) and flagella synthesis (fliN) had a reduced capacity to attach to roots as determined by bacterial counts and by confocal laser scanning microscopy. CONCLUSIONS This study indicates that E. coli K12 has the capability to colonize lettuce roots by using attachment genes and can readily adapt to the rhizosphere of lettuce plants. SIGNIFICANCE AND IMPACT OF THE STUDY Results of this study show curli production and biofilm modulation genes are important for rhizosphere colonization and may provide useful targets to disrupt this process. Further studies using pathogenic strains will provide additional information about lettuce-E. coli interactions.

Abstract
Abstract
The mechanism of the intestinal transport of enoxacin, an orally active fluoroquinolone antibiotic, has been investigated using brush-border membrane vesicles isolated from rat small intestine. The initial rate and time-course of enoxacin uptake were considerably dependent upon the medium pH (pH 5·5 > pH 7·5) and upon the percent ionization of the carboxyl group (pKa 6·2, anionic charge), namely, the degree of uptake of cationic form was higher than that of the zwitterionic form. There was evidence of transport into the intravesicular space as shown by the effect of extravesicular medium osmolarity on enoxacin uptake at steady state (30 min). This transport across the brush-border membrane was stimulated by the valinomycin-induced K+-diffusion potential (interior negative) and an outward H+-diffusion potential. Furthermore, changing the pH of the medium from 5·5 to 7·5 significantly decreased the effect of valinomycin-induced K+-diffusion potential on the enoxacin uptake. These results suggest that the uptake behaviour of the cationic form of enoxacin plays an important role in the intestinal absorption process of enoxacin.

Abstract
Abstract
The uptake of orally active cephalosporins, ceftibuten and cephradine, by intestinal brush-border membrane vesicles isolated from man, rat and rabbit was studied. In the presence of an inward H+ gradient, ceftibuten but not cephradine was taken up into intestinal brush-border membrane vesicles of man and rat against the concentration gradient (overshoot phenomenon). In rabbit jejunal brush-border membrane vesicles, the uptake of both cephalosporins in the presence of an inward H+ gradient exhibited the overshoot phenomenon. In human and rat vesicles, the initial uptake of ceftibuten was strongly inhibited by compound V, an analogue of ceftibuten, but the uptake of cephradine was not affected by any of the cephalosporins tested, whereas in the rabbit brush-border membrane vesicles, initial uptake of both ceftibuten and cephradine were markedly inhibited by all cephalosporins and dipeptides used. These results suggest that the transport characteristics of human and rat intestinal brush-border membrane for cephalosporins are comparable, and that rabbit is an inadequate animal for investigating the transport characteristics of β-lactam antibiotics.

Abstract
Heart and cerebrovascular diseases such as arteriosclerosis and myocardial ischemia dysfunction are currently among the main causes of death in developed countries. Recently, wave intensity (WI), which is an index used to obtain the force of cardiac contraction, has been investigated as a method for early-stage diagnosis of the above-mentioned diseases. Nevertheless, experimental tests have proven that the manual measurements of WI by means of commercial ultrasonic diagnostic systems require too much time and can be affected by the operator's skills. For this purpose, the introduction of robotic-assisted technology has advantages in terms of repetitiveness and accuracy of the measurement procedure. Therefore, at Waseda University, the development of a carotid blood flow measurement system has been proposed to support doctors while using ultrasound diagnostic equipment to measure the WI. This robotic system is composed of a serial robot with a wrist having a six-degree-of-freedom (6-DOF) parallel mechanism. The main focus is to obtain a suitable workspace performance of the 6-DOF parallel mechanism wrist. In this paper, a workspace analysis is carried out on a wrist prototype built for the Waseda-Tokyo Women's Medical Aloka Blood Flow Measurement System No.1 Refined (WTA-1R). Then, mechanical design enhancements are proposed and validated to provide a suitable workspace performance both as reachable workspace and dexterity, and a refined prototype WTA-1RII has been built.

Abstract
Three experiments were conducted to develop methods to control the amount of water loss and to evaluate the metabolic effects of water condition in the White Leghorn breeder eggs during incubation. One hundred twenty, 54, and 90 Julia strain White Leghorn breeder eggs were incubated at 37.8 degrees C, 60% RH in experiments 1, 2, and 3. In experiment 1, eggs were drilled with various bore diameters of 0, 0.5, 1, 2, 3, 4, and 5 mm on the blunt end of the eggshell. In experiment 2, 4 x 4 mm(2) windows were cut into the eggs or the eggs were drilled with 5 holes of bore diameter 2 mm on the blunt end of eggshell. In experiment 3, eggs were drilled with 1, 3, 5, and 7 holes of diameter 2 mm on the blunt end of eggshell. Eggs were treated on d 3 of each experiment and the amount of water loss was recorded on d 19 of incubation. Embryo growth was evaluated in experiments 2 and 3. In addition, the livers of embryos were collected in the 0-, 1-, 3-, and 5-hole treatment groups after weighing eggs to determine 3-hydroxy acyl coenzyme A dehydrogenase activity. In experiment 1, although higher water loss was observed in all windowed eggs than in control, there were no differences in amount of water loss among all bore diameters. Accordingly, that was not successful to control amount of water loss. In experiment 2, higher water loss was observed in drilled eggs at the same levels in windowed eggs as in control. Drilling holes was a more useful treatment to control amount of water loss on incubated eggs than windowing. In experiment 3, amount of water loss increased linearly with increasing number of holes on the blunt end of eggshell. Hepatic 3-hydroxy acyl coenzyme A dehydrogenase activity increased with increasing the number of drilled holes.

Abstract
A new quantum control scheme for general multilevel systems using intense laser fields is proposed. In the present scheme, the target subspace consisting of several quantum levels is effectively isolated by applying intense cw lasers with specific conditions. The formulation is carried out using the Green function with the help of projection operator method. Dynamics of the isolated target subspace is governed by an effective Hamiltonian. The developed scheme is applied to the quantum control of dissipative four- and five-level systems. It is clarified that the present method makes it possible not only to manipulate the coherent population dynamics but also to suppress the dissipative dynamics.

Abstract
Many clinical studies demonstrate that complete revascularization with total arterial grafts leads to the best late surgical results. Though off-pump coronary artery bypass grafting (CABG) is superior to on-pump CABG (ONCABG) in morbidity and mortality, some coronary surgeons feel it difficult to revascularise multi-vessel disease completely without cardiopulmonary bypass (CPB). Acute conversion from off-pump to on-pump results in increased major complications and high mortality. For the patients with high risk for CPB, coronary revascularization should be performed without CPB even if completeness is failed. It seems to be reasonable to adopt ONCABG for low risk patients who need many anastomoses in the posterior wall of the heart.
