Abstract
Abstract
Aims
The Academic Research Consortium for High Bleeding Risk (ARC-HBR) presents a bleeding risk assessment in antithrombotic therapy for patients post percutaneous coronary intervention (PCI). In Japanese patients, heart failure (HF), peripheral vascular disease, and frailty are established as bleeding risk factors in addition to ARC-HBR. However, it is unknown whether left ventricular function or severity of HF is associated with HBR. The aim of this study was to investigate the association between the severity of HF measured by BNP and future bleeding events after PCI.
Methods
Clinical Deep Data Accumulation System (CLIDAS), a multicenter database with 7 tertiary medical hospitals in JAPAN, was developed to collect data directly for patient characteristics, medications, laboratory test, physiological test, cardiac catheterization and PCI treatment in electronic medical records using Standardized Structured Medical Information eXchange Extended Storage (SS-MIX). This retrospective analysis using CLIDAS database included 7160 patients who underwent PCI during April 2014 and March 2020 in the participating hospitals and also who have completed 3-year follow-up were divided into two groups: No HF (n=6645) and HF (n=515). HF patients were furthermore divided based on high BNP (≥100 pg/ml) group (n=384) and low BNP (<100 pg/ml) group (n=131). Primary outcome was defined as bleeding events according to the moderate and severe bleeding in the GUSTO classification. In addition, secondary endpoint was major adverse cardiovascular events (MACE) defined as a composite of cardiac death, myocardial infraction and stroke.
Results
Multivariable Cox regression adjusted for age, sex, BMI, acute coronary syndrome, hypertension, diabetes, dyslipidemia, chronic kidney disease, hemodialysis, previous PCI, previous coronary artery bypass grafting, prior myocardial infraction, prior stroke, prior atrial fibrillation, prior PVD, left main trunk disease, multivessel disease, and anticoagulants use showed that HF with high BNP was significantly associated with bleeding events (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.10–2.50), MACE (HR, 2.16; 95% CI, 1.60–2.90), and all-cause death (HR, 1.74; 95% CI, 1.30–2.33), but not HF with low BNP.
Conclusions
The CLIDAS real-world database revealed that HF with high BNP was associated with future bleeding events, suggesting that bleeding risk might be altered depending on severity of HF.

Abstract
Abstract
Background
The use of β-blockers has the effect of improving the prognosis of patients with ischemic heart disease (IHD). One of the underlying mechanisms is a decrease in the cardiac load due to a reduction in the heart rate.
Purpose
To clarify the relationships among the pulse rate, the use of β-blockers, and the prognosis in patients with IHD in a multicenter study using a storage system.
Methods
The Clinical Deep Data Accumulation System (CLIDAS) collects (1) basic patient information, prescriptions, and laboratory data from electronic medical records from the Standardized Structured Medical Information eXchange (SS-MIX2) standard storage, and (2) the results of physiological tests, cardiac catheterization, and cardiac catheter intervention reports from the SS-MIX2 extended storage. 8540 cases who underwent cardiac catheterization from 6 university hospitals and the national cardiovascular center in Japan were registered (male: 77%, average age: 70.2 years). We evaluated these patients' pulse rate at admission and at the discharge of cardiac catheterization in 6,598 patients. We divided the pulse rates at discharge into quartiles (Q1: <60, Q2: 60–66, Q3: 67–75, Q4: ≥76 bpm), and we analyzed the relationship between the pulse rate and the prognosis by dividing the patients into the stable angina group (n=2,631) and the acute coronary syndrome (ACS) group (n=2,394). Regarding the use of β-blockers, we compared the pulse rates of the patients taking carvedilol (n=1,728) and those taking bisoprolol (n=2,761) at admission and discharge. Major adverse cardiovascular events (MACE) were defined as cardiovascular death, non-fatal myocardial infarction, unstable angina, heart failure, stroke, and other hospitalized cardiovascular events.
Results
A total of 600 MACEs occurred during an average observation period of 890 days. The incidence of cardiovascular events was significantly higher in the Q4 patients in the stable angina group (hazard ratio 1.79, 95% confidence interval 1.32–2.41, but there was no significant difference among the four pulse rate subgroups in the ACS group. The bisoprolol-treated patients had lower pulse rates at discharge (67.4±12.2 vs. 68.8±11.8 bpm, p<0.001) and a lower percentage of patients in the Q4 group (21.2 vs. 24.9%, p=0.005) compared to the carvedilol-treated patients. The pulse rate at admission was similar in the bisoprolol- and carvedilol-treated patients (74.3±19.3 vs. 73.2±29.5 bpm, p=0.328).
Conclusion
In a real-world database using a storage system, a pulse rate of ≤75 bpm was associated with a good prognosis in patients with ACS. Compared to carvedilol, bisoprolol was associated with a decreased pulse rate at discharge.

Abstract
Abstract
Background
Japanese clinical guidelines recommend a stratification of the risks and LDL-cholesterol (LDL-C) treatment goals for patients with coronary artery disease after percutaneous coronary intervention (PCI), i.e. <100 mg/dL for normal risk patients and <70 mg/dL for high risk patients; however, less is known about the association between baseline LDL-C values and long-term prognosis.
Purpose
To investigate the association between LDL-C goals and baseline LDL-C levels in relation to major adverse cardiovascular events (MACE) among high-risk patients after PCI, using a real-world database.
Methods
We developed the Clinical Deep Data Accumulation System (CLIDAS) that acquires clinical data directly from hospital information system, and implemented the system in 6 university hospitals and the national cardiovascular center in Japan. The CLIDAS database accumulates data regarding patient background, laboratory data, prescriptions, electrocardiogram, echocardiogram, PCI report, and long-term prognosis. We retrospectively analyzed 8540 consecutive patients who underwent PCI during April 2014 and March 2020 in participating hospitals, and classified them into the normal risk group (n=3712, 43%) and the high risk group [n=4828, 57%, with any of acute coronary syndrome (ACS), familial hypercholesterolemia (FH), or diabetes with additional risk factor(s)], for which LDL-C goals are <100 mg/dL and <70 mg/dL, respectively, according to the Japanese Atherosclerosis Society guidelines or the diagnosis and prevention of atherosclerotic cardiovascular diseases. The primary outcome was the time to first occurrence of MACE, a composite of cardiovascular death, stroke, myocardial infarction, and coronary revascularization in associations with baseline LDL-C levels and patient background.
Results
Proportion of male (77% vs. 77%) and age (71±11 vs. 70±11) were similar between 2 groups. The prevalence of ACS at the index PCI (0% vs. 62%), FH (0% vs. 2%), hypertension (61% vs. 86%), diabetes (11% vs. 67%), dyslipidemia (73% vs. 84%), hemodialysis (4% vs. 9%), peripheral artery disease (5% vs. 9%), smoking (16% vs. 30%), and prescription of statins (79% vs. 86%) were significantly higher in the high risk group. Among patients in the high risk group, but not in the normal risk group, baseline LDL-C <70 mg/dL was paradoxically associated with higher risk of MACE (P<0.0001 by Log-rank test) (Figure). The Cox proportional hazard model confirmed that the high risk group (risk ratio 1.54, 95% CI [1.31–1.81]), baseline LDL-C <70mg/dL (risk ratio 1.44, 95% CI [1.18–1.75]), baseline age (risk ratio 1.36, 95% CI [1.28–1.45] per 10 year), and prescription of statins (risk ratio 0.80, 95% CI [0.66–0.96]) were significantly associated with the risk of MACE in this population.
Conclusion
The CLIDAS real-world database revealed that baseline low LDL-C paradoxically associated with an increased risk of MACE among guideline-defined high risk patients after PCI.

Abstract
Abstract
Background
Mitochondrial aldehyde dehydrogenase 2 (ALDH2) detoxifies toxic aldehydes including those generated during ischemia/reperfusion (I/R) injury in acute myocardial infarction. The deficient variant ALDH2 genotype (ALDH2*2) is prevalent among East Asians. We examined whether ALDH2*2 exacerbates I/R injury in Japanese patients with acute ST-segment elevation myocardial infarction (STEMI) utilizing Mendelian randomization.
Methods and results
The study subjects comprised 248 Japanese patients with STEMI (187 men and 61 women, mean age 67.1±11.5) who underwent successful primary percutaneous coronary intervention. Of these patients, 129 (52.0%) were the carriers of ALDH2*2 and 119 (48.0%) those of wild ALDH2*1/*1 on genotyping by direct application of the TaqMan polymerase chain system. There were no differences in clinical characteristics between the ALDH2*2 and ALDH2*1/*1 group except lower alcohol habit in the ALDH2*2 group. However, the peak plasma levels of creatine phosphokinase myocardial binding (CKMB), a marker of myocardial injury, were significantly higher (a median 234.0 vs 150.0 U/L, P<0.001 in the ALDH2*2 group. Furthermore, the peak CKMB levels were higher in ALDH2*2 group in men (a median 2 75.0 vs 144.9 U/L, P<0.001) but not in women (P=0.855) and there was a significant interaction between sex and ALDH2*2 on I/R injury (χ2=8.362, P=0.004).
Conclusions
The peak plasma levels of CKMB were higher in STEMI patients with ALDH2*2 than in those with ALDH2*1/*1 among men but not women. These findings identified deficient ALDH2 activity to be targeted for treatment of STEMI specifically in men with ALDH2*2.

Abstract
Abstract
Background
Although carotid intima-media thickness (IMT) is an established marker of atherosclerosis and carries independent risk for cardiovascular disease, its possible association with subclinical cardiac dysfunction has not been extensively evaluated. Left ventricular global longitudinal strain (LVGLS) and peak left atrial longitudinal systolic strain (PALS) can detect subclinical left heart dysfunction.
Purpose
This study aimed to investigate the association between carotid IMT and subclinical left heart dysfunction in a large sample of the general population without overt cardiac disease.
Methods
We examined 1,161 participants who underwent extensive cardiovascular examination. Ultrasonography of common carotid artery was performed for the measurement of maximal carotid IMT. LVGLS and PALS were assessed by 2-dimensional speckle-tracking echocardiography.
Results
Mean age was 62±12 years, and 56% were male. The prevalence of abnormal LVGLS (>−18.6%) and PALS (<31.4%) was greatest in the upper quartile of carotid IMT (both p<0.001; Figure). In multivariable analyses, carotid IMT was associated with abnormal LVGLS (adjusted odds ratio = 1.33 per 1SD increase of IMT, p=0.003) as well as PALS (adjusted odds ratio = 1.33 per 1SD increase of IMT, p=0.005) independent of traditional cardiovascular risk factors, echocardiographic parameters including LV ejection fraction, LV mass index and diastolic dysfunction, and pertinent laboratory parameters. The independent association between carotid IMT and PALS persisted even after adjustment for LVGLS. When carotid IMT was examined as a categorical variable, the upper quartile of carotid IMT carried a significant risk of abnormal LVGLS and PALS in a fully-adjusted model including echocardiographic and laboratory parameters (adjusted odds ratio 2.27 and 3.03 vs. lower quartile, both p<0.01).
Conclusion
Participants with increased IMT had significantly impaired LV and LA function in an unselected community-based cohort. This association may be involved in the higher incidence of cardiovascular disease in individuals with increased carotid IMT.

Abstract
Abstract
Background
Increased arterial stiffness has been proposed as one of the key mechanisms of incident heart failure with preserved ejection fraction (HFpEF). However, the possible association between arterial stiffness and subclinical left ventricular (LV) dysfunction and possible sex-specific differences remain unclarified. LV strain is emerging as a highly sensitive tool to unmask early LV abnormalities.
Purpose
We investigated whether increased arterial stiffness is independently associated with subclinical LV dysfunction in a large community-based cohort without overt cardiovascular disease.
Methods
We examined 1,155 participants who underwent extensive cardiovascular examination. Speckle-tracking echocardiography was employed to assess LV global longitudinal strain (LVGLS) and circumferential strain (GCS), and arterial stiffness was assessed by cardio-ankle vascular index (CAVI).
Results
Mean age was 62±12 years, and 56% were male. CAVI as continuous variable was associated with abnormal LVGLS (>−18.6%), independent of cardiovascular risk factors and pertinent laboratory and echocardiographic parameters (adjusted odds ratio [OR] 1.23, p=0.034), whereas there was no relationship with LVGCS. In sex-stratified analysis, more pronounced association between quartiles of CAVI and abnormal LVGLS was observed in women than in men (unadjusted OR = 6.43 in women and 2.46 in men for upper quartile vs. lower quartile, both p<0.01; Figure). Multivariable analyses demonstrated that CAVI was significantly associated with abnormal LVGLS independent of cardiovascular risk factors in both sexes. However, after further adjustment for LV mass index and diastolic parameters, the independent association persisted in women (adjusted OR 1.49, p=0.041), but not in men (adjusted OR 1.15, p=0.209).
Conclusion
Increased arterial stiffness was independently associated with decreased LVGLS even in the absence of overt cardiovascular disease; a sex-specific pattern exists in the alteration of vascular-ventricular coupling, which might partially explain the greater susceptibility to HFpEF in women.

Abstract
Abstract
Background
American College of Cardiology (ACC) and American Heart Association (AHA) revised their guideline for hypertension in 2017, and the threshold of normal blood pressure (BP) was lowered, in the perspective of the prevention of optimal prevention of cardiovascular diseases. On the other hand European Society of Cardiology and European Society of Hypertension updated their guideline in 2018. However, the cut off value of blood pressure for hypertension was not changed (sBP ≥ 140 mmHg or dBP ≥ 90 mmHg). Therefore, the validity of the updated guideline of ACC/AHA still remains controversial, and there is so far no evidence regarding the BP category according to the ACC/AHA guidelines in general population.
Purpose
We aimed to clarify the association between the updated BP classification and carotid intima-media thickness (IMT), as a marker of subclinical atherosclerosis, in general population using a community-based cohort.
Methods
We analyzed 1,241 subjects undergoing medical check-ups at the University of Tokyo Hospital. Study subjects were categorized into 3 groups based on their BP levels: normal pressure (sBP < 130 mmHg and dBP < 80 mmHg); stage 1 hypertension (130 mmHg ≤ sBP < 140 mmHg or 80 mmHg ≤ dBP< 90 mmHg); and stage 2 hypertension (sBP ≥ 140 mmHg or dBP ≥ 90 mmHg, including subjects prescribed with antihypertensive agents). We defined carotid plaque as IMT ≥ 1.1 mm.

Out of 1,241 subjects, 556 patients (44.8%) were categorized in the normal BP group, whereas 236 subjects (19.0%) and 449 subjects (36.2%) were categorized in the stage 1 and stage 2 hypertension groups, respectively. Among subjects categorized in the stage 2 hypertension group, 348 subjects (77.5%) patients were taking antihypertensive medications. Percentage of male gender, and age increased with BP category. Classical CVD risk factors such as diabetes mellitus and hypercholesterolemia were common in subjects in the hypertension groups. IMT increased as the BP category progressed from normal BP to stage 2 hypertension. The prevalence of carotid plaque also increased with an increase in BP. Univariate regression analysis showed the linear association between the BP category and prevalence of carotid plaque. Multivariable logistic regression analysis demonstrated that BP category as well as age ≥60 years, male gender, body mass index ≥25 kg/m2, and diabetes mellitus were independently associated with carotid plaque formation. BP category was associated with the prevalence of carotid plaque formation in any subgroup divided by age (< 60 years old, and ≥60 years old) or gender.
Conclusions
Thickening of IMT developed in stage 1 hypertension, and further increased in stage 2 hypertension even in general population, indicating the importance of the therapeutic intervention according to the updated ACC/AHA guideline for hypertension.

Abstract
Abstract
Background
Increased arterial stiffness is recognized as an independent risk factor for atrial fibrillation, although the pathophysiological mechanisms remain unclear. Cardio-ankle vascular index (CAVI) is emerging as an important tool to assess arterial stiffness noninvasively which is derived from the concept of stiffness β index and is less dependent on blood pressure at the time of measurement than pulse wave velocity.
Purpose
This study aimed to investigate the association of arterial stiffness with left atrial (LA) volume and phasic function in a community-based cohort.
Methods
We included 1,156 participants without overt cardiovascular disease who underwent extensive cardiovascular examination. Arterial stiffness was evaluated by CAVI. Speckle-tracking echocardiography was employed to evaluate LA phasic function including reservoir, conduit and pump strain as well as left ventricular global longitudinal strain (LVGLS).
Results
CAVI was negatively correlated with reservoir and conduit strain (r=−0.37 and −0.45, both p<0.001; Figure), whereas weakly, but positively correlated with LA volume index and pump strain (r=0.12 and 0.09, both p<0.01). In multivariable analysis, CAVI was significantly associated with reservoir and conduit strain independent of traditional cardiovascular risk factors, pertinent laboratory parameters and LV morphology and function including LVGLS (standardized β=−0.22 and −0.26, respectively, both p<0.001), whereas there was no independent association with LA volume index and pump strain. In the categorical analysis, the abnormal CAVI (≥9.0) carried the significant risk of impaired reservoir (<31.4%) and conduit (<12.4%) strain (adjusted odds ratio = 2.63 and 3.71 vs. normal CAVI, both p<0.01) in a fully-adjusted model including laboratory and echocardiographic parameters.
Figure 1
Conclusion
Arterial stiffness was independently associated with LA reservoir and conduit function, even in the absence of overt cardiovascular disease. This association may explain the higher incidence of atrial fibrillation in individuals with increased arterial stiffness.

Abstract
Abstract
Introduction
Obesity is a common and independent risk factor for all-cause mortality. More specifically, obesity is a major component of atherosclerosis in association with metabolic disorders including metabolic syndrome (MetS), resulting in various cardiovascular diseases (CVD). Alternatively, obese subjects without MetS are prevalent, also referred to as metabolically healthy obesity (MHO). However, most preceding studies regarding MHO have been limited by small cohorts. Therefore, the effect of MHO on atherosclerosis in the general population remains unclear.
Purpose
In this study, we sought to clarify the effect of MHO on carotid intima-media thickness (IMT) as a marker of early stage atherosclerosis using a community-based cohort in general population.
Methods
We examined subjects who underwent medical check-up at our University Hospital. We defined obesity as body mass index ≥25.0 kg/m2. Abdominal obesity, defined as waist circumstance at umbilical level ≥85 cm in men and ≥90 cm in women, was obligatory for the diagnosis of MetS. In addition to abdominal obesity, any two of the following three abnormalities should be observed for the diagnosis of MetS, [1] Dyslipidemia: triglyceride ≥150 mg/dL, HDL-C <40 mg/dL, or use of lipid lowering medication, [2] Hypertension: systolic blood pressure ≥130 mmHg, diastolic blood pressure ≥85 mmHg, or use of antihypertensive medication, and [3] Hyperglycemia: fasting plasma glucose ≥110 mg/dL or use of hypoglycemic medication. MHO was defined as obese subjects without MetS, whereas we defined metabolically unhealthy obesity (MUO) as obese subjects with MetS. We defined carotid plaque as IMT ≥1.1 mm.
Results
Among 1,241 subjects, 857 subjects (69%) were categorized in the normal body weight group, whereas 275 subjects (22%) were categorized as MHO, and 109 subjects (9%) were categorized as MUO. Compared to non-obese subjects, prevalence of classical cardiovascular risk factors including hypertension, diabetes mellitus, and dyslipidemia increased in subjects with MHO, and further increased in those with MUO. IMT was higher in obese subjects compared to those without obesity. Similarly, the prevalence of carotid plaque formation was also higher in obese subjects. Multivariable logistic regression analysis demonstrated that age ≥60 years, male sex, hypertension, diabetes mellitus, MHO subjects (Odds ratio [OR]; 1.6, p=0.005), and MUO subjects (OR 1.7, p=0.04) were independently associated with carotid plaque formation. There was no statistical difference in the risk of carotid plaque formation between subjects with MHO and MUO.
IMT and Carotid Plaque
Conclusions
IMT and the prevalence of carotid plaque are higher in both subjects with MHO and MUO compared to non-obese subjects in the general population. We need to take obesity regardless of the presence of MetS into consideration as high-risk subjects for subsequent CVD.

Abstract
Abstract
Background
Cigarette smoking is closely associated with the development of cardiovascular diseases (CVD), and the European Society of Cardiology/European Atherosclerosis Society (ESC/EAS) guidelines recommend smoking bans.On the other hand, the relationship between cigarette smoking and subclinical atherosclerosis has not been fully studied. Carotid intima-media thickness (cIMT) is commonly used as a subclinical atherosclerosis marker, and a carotid plaque feature is also known to be an important predictor of cardiovascular diseases.
Purpose
We sought to clarify the association between cigarette smoking and subclinical atherosclerosis by evaluating carotid plaque including cIMT and carotid plaque features in general population.
Methods and results
Among 1,209 participants with no prior coronary artery disease who received a medical check-up with cardiovascular examination at our institution, 450 participants (37.2%) were smokers (including both past and current smokers). We defined carotid plaque as cIMT ≥1.1 mm and high-risk plaque as carotid plaque with hypoechoic dominant and/or plaque ulceration. The value of cIMT and the rate of carotid plaque were not different between smokers and never smokers (Figure A & B). However, the rate of carotid high-risk plaque was significantly higher in participants with smokers than those with never smokers (29.7%, vs 23.5%, p=0.011) (Figure C). Even after adjustment with covariates including age, gender and traditional cardiovascular risk factors, cigarette smoking was independently associated with high-risk plaque formation (odds ratio 1.384, 95% CI 1.020–1.877; p=0.037). According to the subgroup analysis classified by age, cigarette smoking was associated with not only the development of high-risk plaque but also the increased value of cIMT in the subgroup over 60 years old, whereas only the rate of high-risk plaque was higher in smokers than never smokers in the subgroup under 60 years old.
Carotid plaque and smoking
Conclusion
The development of high-risk carotid artery plaque may precede thickening of cIMT in cigarette smokers, suggesting that the novel insight for the pathological mechanism underlying cardiovascular events and cigarette smoking.

Abstract
OBJECTIVE The impact of religious/spiritual activities on clinical outcomes in patients with serious mental illnesses remains controversial, which was addressed in this international cross-sectional study. METHOD Three-hundred sixty-nine subjects were recruited from Austria (n = 189) and Japan (n = 180), consisting of 112 outpatients with paranoid schizophrenia, 120 with bipolar I disorder (DSM-IV), and 137 healthy controls. Religiosity was assessed in terms of attendance and importance of religious/spiritual activities, while resilience was assessed using the 25-item Resilience Scale. General linear models were used to test whether higher religiosity will be associated with higher resilience, higher social functioning, and lower psychopathology. The association between levels of spiritual well-being and resilience was also examined. RESULTS Attendance of religious services (F[4,365] = 0.827, P = 0.509) and importance of religion/spirituality (F[3,365] = 1.513, P = 0.211) did not show significant associations with resilience. Regarding clinical measures, a modest association between higher importance of religion/spirituality and residual manic symptoms was observed in bipolar patients (F[3,118] = 3.120, P = 0.029). In contrast to the findings regarding religiosity, spiritual well-being showed a strong positive correlation with resilience (r = 0.584, P < 0.001). CONCLUSION The protective effect of religiosity in terms of resilience, social functioning, and psychopathology was not evident in our sample. Spiritual well-being appears more relevant to resilience than religiosity.

Abstract
Objective Gastric inhibitory polypeptide plays a role in glucose and lipid metabolism and is associated with obesity and insulin resistance. The objective of this study is to confirm the anti-obesity effects of the gastric inhibitory polypeptide receptor antagonist, SKL-14959, on diet-induced obesity mice. Method Diet-induced obesity mice at 20 weeks of age were administered with or without SKL-14959 for 96 d. Body weight and food intake were monitored throughout the experiment. Mice were sacrificed, and physiological and biochemical markers were measured, and then histochemical and gene expression analyses were also performed. In further studies, mice were orally gavaged with [14C]-oleic acid to investigate the excursion of digested lipids. Results SKL-14959 significantly suppressed weight gain without affecting food intake, decreased triacylglycerol contents in the liver and the muscle and the intensity stained with oil-red in the liver. It also improved plasma glutamic pyruvic transaminase and 3-hydroxybutyrate levels in addition to notably down-regulated relative gene expression of srebf1 and dgat1 in the liver despite not altering in the adipose tissue. Furthermore, SKL-14959 showed remarkable inhibition of lipid uptake in the adipose tissue after the oil challenge. Conclusion SKL-14959 inhibited lipids uptake and improved lipids metabolism, results in suppression of body-weight gain.

Abstract
Removable prosthodontics are often associated with mechanical troubles in daily use, such as fracture or deformation. These troubles render prostheses unusable and reduce wearers' QOL. Various reinforcements are used to prevent such problems, but consensus on reinforcement has not been reached. This review aimed to summarise the effects of reinforcement and to propose favourable reinforcement based on material, design and position in the prostheses. Initially, 139 articles were selected by electronic and manual searches. After exclusion of 99 articles based on the exclusion criteria, 40 articles were finally included in the review. Electronic searches were performed for articles published from 2005 to 2015 in PubMed, EMBASE, MEDLINE and Cochrane Library, and manual searches were performed in 10 journals relevant to the topic of removable prosthodontics. For in vitro studies, certain dental alloys and fibres were mainly used. Their forms were different, including complicated forms in dental alloys and various forms in fibres. The materials were examined for mechanical properties like fracture strength, flexural strength and elastic modulus and compared with one another or without reinforcement. There were a few clinical studies and one longitudinal study. Cast metal reinforcement seemed to be most favourable in terms of fracture toughness and stiffness. The most favourable forms differed depending on the prostheses, but placement around thin and deformable areas was effective. However, randomised or longitudinal clinical reports and comparative clinical studies on the use of reinforcement were still lacking and such studies are necessary in the future.

Abstract
BACKGROUND Health-related quality of life (HRQOL) is significantly affected in individuals with schizophrenia or bipolar I disorder (BD-I). The current study investigated whether symptomatic remission and resilience might differently impact HRQOL in these patients. METHODS Fifty-two patients with schizophrenia and 60 patients suffering from BD-I from outpatient mental health services as well as 77 healthy control subjects from the general community were included into a cross-sectional study. HRQOL and resilience were assessed using the WHOQOL-BREF and the Resilience Scale. In patients, psychopathology was quantified by the Positive and Negative Syndrome Scale or the Montgomery Asberg Depression Rating Scale and the Young Mania Rating Scale, respectively. RESULTS Notably, both patient groups showed lower HRQOL and resilience compared to control subjects, non-remitted patients indicated lower HRQOL than remitted ones. The effect of remission on HRQOL was significantly larger in patients with BD-I than in those with schizophrenia but did not explain the difference in HRQOL between groups. Resilience predicted HRQOL in all three groups. When accounting for the effect of resilience among remitted patients, only the difference in HRQOL between schizophrenia patients and control subjects was significant. CONCLUSION These findings demonstrate the impact of symptomatic remission and resilience on HRQOL of both patients suffering from schizophrenia and BD-I and indicate that these factors are especially relevant for HRQOL of patients with BD-I.

Abstract
BACKGROUND AND PURPOSE In patients with metastatic brain tumors after gamma knife radiosurgery, the superiority of PET using 11C-methionine for differentiating radiation necrosis and recurrent tumors has been accepted. To evaluate the feasibility of MR permeability imaging, it was compared with PET using 11C-methionine, FDG-PET, and DWI for differentiating radiation necrosis from recurrent tumors. MATERIALS AND METHODS The study analyzed 18 lesions from 15 patients with metastatic brain tumors who underwent gamma knife radiosurgery. Ten lesions were identified as recurrent tumors by an operation. In MR permeability imaging, the transfer constant between intra- and extravascular extracellular spaces (/minute), extravascular extracellular space, the transfer constant from the extravascular extracellular space to plasma (/minute), the initial area under the signal intensity-time curve, contrast-enhancement ratio, bolus arrival time (seconds), maximum slope of increase (millimole/second), and fractional plasma volume were calculated. ADC was also acquired. On both PET using 11C-methionine and FDG-PET, the ratio of the maximum standard uptake value of the lesion divided by the maximum standard uptake value of the symmetric site in the contralateral cerebral hemisphere was measured (11C-methionine ratio and FDG ratio, respectively). The receiver operating characteristic curve was used for analysis. RESULTS The area under the receiver operating characteristic curve for differentiating radiation necrosis from recurrent tumors was the best for the 11C-methionine ratio (0.90) followed by the contrast-enhancement ratio (0.81), maximum slope of increase (millimole/second) (0.80), the initial area under the signal intensity-time curve (0.78), fractional plasma volume (0.76), bolus arrival time (seconds) (0.76), the transfer constant between intra- and extravascular extracellular spaces (/minute) (0.74), extravascular extracellular space (0.68), minimum ADC (0.60), the transfer constant from the extravascular extracellular space to plasma (/minute) (0.55), and the FDG-ratio (0.53). A significant difference in the 11C-methionine ratio (P < .01), contrast-enhancement ratio (P < .01), maximum slope of increase (millimole/second) (P < .05), and the initial area under the signal intensity-time curve (P < .05) was evident between radiation necrosis and recurrent tumor. CONCLUSIONS The present study suggests that PET using 11C-methionine may be superior to MR permeability imaging, ADC, and FDG-PET for differentiating radiation necrosis from recurrent tumors after gamma knife radiosurgery for metastatic brain tumors.

Abstract
BACKGROUND Impaired exercise capacity and muscle weakness are important characteristics of liver transplantation recipients. Perioperative rehabilitation has been introduced to promote early mobilization of patients and to prevent postoperative pulmonary complications. However, it is unknown how physical status recovers during the hospital stay after a liver transplant. The purpose of this study was to evaluate the changes in clinical indicators that represent the functional exercise capacity and muscle strength before and after living donor liver transplantation (LDLT). METHODS We retrospectively reviewed 21 consecutive patients who underwent LDLT with perioperative rehabilitation from April 2014 to December 2015. Twelve patients who were tested for 6-minute walk distance, hand-grip strength, and isometric knee extensor muscle strength before and 4 weeks after LDLT were enrolled. RESULTS At the preoperative baseline, the 6-minute walk distance significantly correlated with the Model for End-stage Liver Disease score and pulmonary functions (vital capacity, forced vital capacity, and forced expiratory volume in 1 second of predictive values). Comparisons between the preoperative and postoperative values revealed significant decreases in weight, Barthel Index, hand-grip strength, and isometric knee extensor muscle strength. Changes in hand-grip strength and isometric knee extensor muscle strength after LDLT correlated with the preoperative Model for End-stage Liver Disease score. CONCLUSIONS Physical functional status had not been fully recovered 4 weeks after LDLT. Further investigation regarding developing a strategy for prevention of muscle atrophy before LDLT and recovery of physical fitness after LDLT would be helpful.

Abstract
Abstract
[Purpose] The Groupe European de Curietherapie-European Society for Therapeutic Radiology and Oncology (GEC-ESTRO) has reported the equivalent outcomes of partial-breast irradiation (PBI) using multicatheter interstitial brachytherapy (MCB) to whole-breast irradiation (WBI) in breast-conserving therapy, showing that the incidence of local recurrence was 1.44% with MCB-PBI and 0.92% with WBI. Based on the trial, MCB-PBI could be considered as an alternative method to WBI for low-risk breast cancer patients. However, it would be difficult to translate it directly into Japanese community practice. After categorization of Japanese patients using the inclusion and exclusion criteria of this trial, our databases were re-evaluated to validate the data for Japanese patients, and the possibility to extend the candidate for MCB-PBI was also investigated.
[Methods] Patients undergoing BCT were retrospectively examined between November 2007 and December 2015. The technique involved an open-cavity implant with a dose of 32 Gy in eight fractions. WBI was performed with a total dose of 50 Gy in fractions of 2 Gy. The 4-year clinical outcomes of MCB-PBI were evaluated in the two distinct categories, and comparisons of outcomes between MCB-PBI and WBI were performed in patients with unfavorable features.
[Results] Of a total of 501 lesions undergoing BCT, 301 lesions were treated with MCB-PBI and 200 lesions with WBI. At a median follow-up time of 52 months, the 4-year rate of ipsilateral breast tumor recurrence (IBTR)-free, disease-free, and overall survival in patients with MCB-PBI and WBI were 98.9% vs. 98.0% (p = 0.56), 97.0% vs. 95.3% (p = 0.78), and 99.6% vs. 98.2% (p = 0.38), respectively. In the exclusion cohort treated with MCB-PBI, IBTR-free and disease-free survival were significantly poorer than in the inclusion cohort.However, no significant differences in the outcomes between the two radiotherapy techniques were demonstrated with respect to either IBTR-FS (95.0% vs. 97.2%, p = 0.24), DFS (95.0% vs. 95.8%, p = 0.31), or OS (100% vs. 99.0%, p = 0.80) in patients with exclusion criteria

ConclusionsTo our knowledge, this study includes the largest cohort of Asian patients undergoing MCB-PBI. Although the retrospective chart review with relatively short follow-up time and small number of patients does not allow reaching any definite conclusion, we could expect the same outcomes by MCB-PBI as those in the GEC-ESTRO trial with respect to the tumor control only for Japanese but for Asian patients with breast cancer. Moreover, no negative impact on the outcomes of MCB-PBI as compared to WBI was not found in patients with exclusion criteria.

Abstract
Disseminated histiocytic sarcoma (HS) was diagnosed on post-mortem examination of a 1.5-year-old African hedgehog (Atelerix albiventris) that was presented in poor physical condition and with diarrhoea. Leucocytosis and a hypoechoic abdominal mass were noted on haematological and ultrasonographical examinations. Gross pathological, histopathological, immunohistochemical and ultrastructural evaluation of the mass supported a diagnosis of disseminated HS. To our knowledge, this report represents the first documentation of disseminated HS in this species.

Abstract
OBJECTIVE Improving quality of life (QoL) is an important objective in the treatment of schizophrenia. The aim of the current study was to examine to what extent resilience, self-esteem, hopelessness, and psychopathology are correlated with QoL. METHOD We recruited 52 out-patients diagnosed with schizophrenia according to DSM-IV criteria and 77 healthy control subjects from the general community. In patients, psychopathology was quantified by the Positive and Negative Syndrome Scale. The following scales were used in both patients and control subjects: the Berliner Lebensqualitätsprofil, the Resilience Scale, the Rosenberg Self-Esteem Scale, and the Beck Hopelessness Scale to assess QoL, resilience, self-esteem, and hopelessness respectively. RESULTS Patients with schizophrenia presented with significantly less QoL, resilience, self-esteem, and hope compared to healthy control subjects. In patients, QoL correlated moderately with resilience, self-esteem, and hopelessness and weakly with symptoms. With respect to the latter, particularly depression and positive symptoms were negatively correlated with QoL. CONCLUSION Our results highlight the complex nature of QoL in patients suffering from schizophrenia. They underscore that significant efforts are necessary to enhance resilience and self-esteem and to diminish hopelessness as well as affective and positive symptoms in patients with schizophrenia.

Abstract
Abstract
Background: Although the rate of breast-conserving surgery (BCS) increased, the receipt of adjuvant radiotherapy after BCS decreased especially for young patients. The long-term daily visit to radiation facilities must be the most relevant barriers to receiving radiation therapy. The use of partial-breast irradiation (PBI) is considered an alternative option. However, there are limited data to be seen how safe PBI is as an option of adjuvant radiation therapy in young patients compared with whole-breast irradiation (WBI). In this report, we reviewed our single-institution experience with PBI compared with WBI in young breast cancer patients.
Methods: We evaluated 443 consecutive patients with T≤3-cm N0–1 breast cancer who underwent breast-conserving therapy (BCT) between November 2007 and May 2015. 268 patients received PBI using interstitial multicatheter brachytherapy. The interstitial brachytherapy was performed in an accelerated fashion with a dose of 32 Gy in eight fractions over 5-6 days. 185 patients received WBI with a dose of 50 Gy in fractions of 2 Gy. Patients with risk factors such as positive margins and young age received a subsequent 10 Gy boost to the tumor bed, and the regional nodal irradiation was added in patients with ≥ 4 positive nodes. Patients who underwent neoadjuvant chemotherapy were excluded from the analysis. Our primary objective was to assess outcome rates of ipsilateral breast tumor recurrence (IBTR), disease-free survival (DFS), and overall survival (OS), and compare the patterns of treatment failures between the cohorts.
Results: Patients aged <50 years with a minimum follow-up period of 6 months were selected for the analysis. Of those patients who could be completely followed, there were 95 women receiving PBI and 81 women receiving WBI. In PBI cohort, 4 patients also received WBI because of adverse histological features with positive nodes or positive margins by final pathology. Median follow-up was 4.0 years for PBI patients and 3.9 years for WBI patients. Median age was 43.9 years old for PBI and 42.1 years old for WBI cohort. Mean tumor size was equivalent for the cohorts (12 mm). Positive lymph nodes were seen more frequently in WBI cohort (9.5% and 29.6%, p < 0.05). There was no significant difference in the 3-year probability of disease-free survival (97.4% and 98.1% for PBI and WBI, respectively; p = 0.95). No breast cancer related death was observed. With our follow-up period, there were 5 IBTR (2.8%). Of these IBTRs, 4 were true recurrences (2 were in PBI and 2 were in WBI). There was 1 elsewhere recurrence in PBI cohort. The actual rate of IBTR was 3.2% and 2.5% in PBI and WBI, respectively (p = 0.64).
Conclusions: We observed equivalent IBTR rates between PBI and WBI cohorts in young breast cancer patients. If there are no differences in survival between the two radiotherapy regimens, PBI may be a better option than WBI after BCS in such a population. To our knowledge, this is the first report describing that the efficacy of PBI after BCS is comparable with WBI in young breast cancer patients in Asia. However, our data are limited by our short median follow-up with small number of patients. The application of PBI should still be carefully considered until mature Phase III trial data are available.

Abstract
AIMS For women with congenital heart defects (CHD), pregnancy may pose a health risk. Sexually active women with CHD without the desire for own children or for whom pregnancy would imply considerable health risks require adequate counselling regarding appropriate contraception. This study gathers data on the contraceptive behaviour of women with CHD from three different cultural regions. METHODS AND RESULTS 634 women with CHD from Germany, Hungary and Japan were surveyed regarding contraception and contraceptive methods (CM) used. The patients were divided into groups according to different criteria such as pregnancy associated cardiovascular risk or "safety" of the contraceptive methods used. 59% of the study participants had already gained experience with CM. The average age at the first time of use was 18.4 years; the German patients were significantly younger at the first time of using a CM than those from Hungary and Japan. Overall the condom was the method used the most (38%), followed by oral contraceptives (30%) and coitus interruptus (11%). The range of CM used in Japan was much smaller than that in Germany or Hungary. Unsafe contraceptives were currently, or had previously been used, by 29% of the surveyed patients (Germany: 25%, Hungary: 37%, Japan: 32%). CONCLUSION Most women with CHD use CM. There are differences between the participating countries. Adequate contraceptive counselling of women with CHD requires considering the individual characteristics of each patient, including potential contraindications. For choosing an appropriate CM, both the methods' "safety", as well as the maternal cardiovascular risk, are important.

Abstract
The polarizer is one of the critical components in a high-power millimeter-wave transmission line. It requires full and highly efficient coverage of any polarization states, high-power tolerance, and low-loss feature. Polarizers with rounded shape at the edge of the periodic groove surface are designed and fabricated by the machining process for a mega-watt long-pulse millimeter-wave transmission line of the electron cyclotron resonance heating system in the large helical device. The groove shape of λ/8- and λ/4-type polarizers for an 82.7 GHz transmission line is optimally designed in an integral method developed in the vector theories of diffraction gratings so that the efficiency to realize any polarization state can be maximized. The dependence of the polarization states on the combination of the two polarizer rotation angles (Φλ/8, Φλ/4) is examined experimentally in a low-power test with the newly developed polarization monitor. The results show that the measured polarization characteristics are in good agreement with the calculated ones.
