Abstract
Abstract
Background
Venous thromboembolism (VTE) is the third frequent acute cardiovascular syndrome in the Europe and Japan. Since direct oral anticoagulants (DOACs) are widely used now, the morbidity and mortality of pulmonary embolism (PE) patients especially associated with cancer needs to be re-evaluated.
Purpose
We evaluated the clinical course of patients with PE mainly treated with DOACs.
Methods
This retrospective observational study was conducted in a single center. The data were collected from the medical record of consecutive patients who received inpatient treatment of PE. In this study, we have compared PE patients with cancer (cancer PE) to those without cancer (non-cancer PE) and evaluated the mortality, recurrent of VTE and major bleedings.
Results
In total, 140 patients were enrolled: 94 patients were cancer-related, and 46 patients were without cancer (Table). The type of the tumor in cancer PE patients were as follows: gastric 8 (9%), esophageal 5 (5%), pancreatic 12 (13%), lung 14 (15%), lymphoma 2 (2%), gynecologic 17 (18%), renal 2 (2%), bile duct 8 (9%), colon 12 (13%), and others 17 (18%).
Kaplan-Meier curve showed that the cumulative all-cause mortality was significantly higher in the cancer PE group (35/94 (37%) vs. 2/46 (4%), P<0.001 (log rank), HR 10.3 [95% CI:2.5–43.3]). The cumulative incidence of recurrent VTE was significantly higher in the cancer PE group (7/94 (7%) vs. 0/46, P=0.03 (log rank)). There was no significant difference in the cumulative incidence of major bleeding between the cancer PE group and the non-cancer PE group (8/94 (9%) vs. 5/46 (11%)).
Conclusions
The risk of recurrent VTE was still higher in cancer PE patients compared to non-cancer PE patients, although DOACs were used. Meanwhile the incidence of major bleeding was comparable in both groups, the risk of bleeding might be acceptable with using DOACs especially in cancer PE patients.

Abstract
Abstract
Background
Abdominal aortic aneurysm (AAA) is a life-threatening disease, while effective and preventive medical treatments remain unestablished.
Purpose
The aim of this study was to evaluate the effect of selective peroxi- some proliferator-activated receptor alpha (PPARα) modulator pemafibrate on AAA formation in mice.
Methods
AAA was induced by subcutaneous infusion of angiotensin II (AngII) in apolipoprotein E-deficient mice for 4 weeks. Treatment by pemafibrate or vehicle was started one week before AngII infusion. Oxidative stress was evaluated by dihydroethidium (DHE) staining.
Results
Prognosis after AngII infusion in pemafibrate-treated mice was significantly better than that in vehicle-treated mice (log-rang test, p=0.035) by reducing the occurrence of fatal AAA rupture. Meanwhile pemafibrate did not significantly reduce maximal diameter of the aorta. Histological findings demonstrated that the expression of collagen in adventitia in pemafibrate-treated mice was significantly greater than that in vehicle-treated mice (p<0.05). Oxidative stress in aorta of pemafibrate-treated mice was significantly reduced comparing to vehicle-treated mice, accompanying by the reduction of mRNA expression of matrix metalloproteinase 2, tumor necrosis factor-α, and interleukin-6 (all p<0.05). Catalase expression in abdominal aortic tissue was increased 1.5-fold in mice treated with pemafibrate than in mice treated with vehicle (p=0.032). In human vascular smooth muscle cells (hVSMC), pemafibrate attenuated AngII-induced oxidative stress (p<0.001), which was canceled by administrating small interfering RNA (siRNA) of PPARα (p<0.001). Furthermore, in hVSMC, pemafibrate increased catalase expression significantly (p<0.001), while this increase was significantly suppressed by knockdown of PPAR-α with siRNA. (p<0.001).
Conclusion
Pemafibrate reduced the rupture of AAA in this murine model, which is associated with anti-oxidative stress via catalase induction.

Abstract
Dental treatment improves the experience of eating by healing illnesses in the oral cavity or through the installation of special devices. However, mastication can often prove difficult for short periods of time after dental treatment, potentially limiting the types of food that can be consumed. Therefore, we proposed a highly nutritious meal strategy for dental outpatients (hereafter, "easy-to-eat meals"). We previously reported patients' subjective assessment of these easy-to-eat meals as determined through a questionnaire survey. The purpose of the present study was to investigate how differences in age affected such assessments. The study participants comprised patients scheduled to undergo dental treatment. They were divided into 2 groups: one of patients aged above and one of those aged below 70 years. All were required to consume provided easy-to-eat meals at the dental hospital directly after treatment and then answer a questionnaire. The questionnaire included items on patient satisfaction with the meals, taste, portion size, convenience, reduction in discomfort, and whether they would consume them again. The format of the questionnaire was a visual analog scale (VAS), ranging from 0 (negative) to 10 (positive). Portion size was to be rated on a scale from 0 ("Not enough") to 10 ("Too much"), with 5 being "Just right". Correlations between the questionnaire items were investigated to determine how they influenced each other. The VAS average for "Reduction in discomfort" was 8.45±1.39 in the non-elderly group and 6.07±2.92 in the elderly group, and the difference was significant (p=0.02); the VAS average for "Taste" was 6.49±2.32 in the non-elderly group and 4.91±0.98 in the elderly group, and the difference was significant (p=0.04). The results of this study suggest that providing such meal plans as nutritional guidance after dental treatment can influence quality of life in elderly patients.

Abstract
BACKGROUND AND PURPOSE The aim was to clarify the features affecting cardiac sympathetic denervation in autopsy-confirmed dementia with Lewy bodies (DLB) patients. METHODS Fifty-four autopsy-confirmed DLB patients were enrolled. Tissue samples of the left ventricular anterior wall were immunostained with anti-tyrosine hydroxylase antibody to identify catecholaminergic nerve axons. Immunostained areas were quantified as residual cardiac sympathetic nerve (CSN) axons and the relationship between the degree of residual CSN axons and clinical and neuropathological features was examined. RESULTS Virtually all patients showed small amounts of residual CSN axons (0.87%, range 0.02%-9.98%), with 50 patients (92.6%) showing <2.0% of residual axons. The patients who showed psychological symptoms within the first year of the disease had significantly more residual CSN axons than the remaining patients did (1.50% vs. 0.40%, P < 0.01). Patients with a short disease duration and neocortical-type Lewy body pathology tended to have more preserved CSN axons, although this difference was not statistically significant. Fifty-three patients (98.1%) who had neurofibrillary tangles in the brain and strong concomitant Alzheimer's disease pathology also had statistically significantly more preserved CSN axons. The patient with the most preserved CSN axons showed different characteristics from the results, except for the first symptom. CONCLUSION Psychological symptoms within the first year of the disease, a short disease duration, neocortical-type Lewy body pathology and strong concomitant Alzheimer's disease pathology may be related to mild CSN degeneration in DLB patients. Thus, DLB patients with broad Lewy body pathology in the brain in the early stages may show mild CSN degeneration.

Abstract
To realize stable negative ion beams for 100 s required in the neutral beam injector of JT-60SA, a physical model to control cesium (Cs) distribution inside the negative ion source has been developed in order to maintain the stable negative ion production at the plasma grid (PG) surface with Cs. In this work, to quantitatively evaluate Cs coverage on the PG, a three-dimensional Cs transportation code was introduced to consider the spatial Cs distribution in the source. The spatial temperature distribution of the chamber wall was also introduced in this model. As a result, the reasonable variation of the Cs coverage for 100 s was obtained, compared to that in the initial model. Based on the modified model, the operational temperature of the chamber wall was proposed to be less than 60 °C to suppress the desorption of Cs in the chamber wall and to sustain the stable negative ion production. In addition, it was also suggested that a slightly higher wall temperature before the operation leads to a decrease in the amount of Cs stored at the chamber wall, resulting in suppression of Cs consumption in the ion source.

Abstract
Photonic-crystal surface-emitting lasers (PCSELs) use the two-dimensional (2D) resonance at the band-edge of a photonic crystal for lasing, and they feature various outstanding functionalities such as high-brightness lasing, arbitrary shaping of beam patterns and on-chip 2D beam steering. In this paper, to investigate the applicability of PCSELs for high-speed operation, we design PCSELs with enhanced in-plane optical feedback, which enable single-mode lasing inside a circular region the diameter of which is less than 10 µm. To realize a strong in-plane confinement of the lasing mode, we increase the one-dimensional coupling coefficients between counter-propagating waves through the careful design of the lattice points. We also introduce an in-plane heterostructure composed of two photonic crystals with different photonic bandgaps and utilize reflection at the boundary of the two photonic crystals in addition to the optical feedback at the band-edge of each photonic crystal. By using three-dimensional finite-difference time-domain method (3D-FDTD), we confirm that the proposed hetero-PCSELs can achieve single-mode lasing operation inside a 9-µm-diameter and possibly realize a 3-dB modulation bandwidth larger than 40 GHz.

Abstract
Long pulse acceleration of hydrogen negative ion beams with the power density over 70 MW/m2 and the pulse length over 100 s has been demonstrated for the first time by using a multi-aperture 3-stage accelerator. Such long pulse acceleration was achieved by integrating the design of beam optics and voltage holding capability to meet the requirements of JT-60SA. By using the newly designed accelerator for JT-60SA, voltage holding at 500 kV with beam acceleration was stably sustained even after 5 g of cesium was seeded, and heat load on each acceleration grid was reduced below the allowable level for long pulse, less than 5% of total acceleration power. As a result, 500 keV, 154 A/m2 for 118 s beam acceleration was achieved, which satisfies the requirement of the negative ion source for JT-60SA. This pulse length of such high-power density beams is longest in the world. In addition, the result contributes to the long pulse acceleration of multi-stage electrostatic accelerators, such as 1 MeV negative ion accelerator for ITER.

Abstract
In innate immunity, multiple autophagic processes eliminate intracellular pathogens, but it remains unclear whether noncanonical autophagy and xenophagy are coordinated, and whether they occur concomitantly or sequentially. Here, we show that Streptococcus pneumoniae, a causative of invasive pneumococcal disease, can trigger FIP200-, PI3P-, and ROS-independent pneumococcus-containing LC3-associated phagosome (LAPosome)-like vacuoles (PcLVs) in an early stage of infection, and that PcLVs are indispensable for subsequent formation of bactericidal pneumococcus-containing autophagic vacuoles (PcAVs). Specifically, we identified LC3- and NDP52-delocalized PcLV, which are intermediates between PcLV and PcAV. Atg14L, Beclin1, and FIP200 were responsible for delocalizing LC3 and NDP52 from PcLVs. Thus, multiple noncanonical and canonical autophagic processes are deployed sequentially against intracellular S. pneumoniae. The Atg16L1 WD domain, p62, NDP52, and poly-Ub contributed to PcLV formation. These findings reveal a previously unidentified hierarchical autophagy mechanism during bactericidal xenophagy against intracellular bacterial pathogens, and should improve our ability to control life-threating pneumococcal diseases. Ogawa, Takada et al. show that Streptococcus pneumoniae triggers the formation of pneumococcus-containing LC3-associated phagosome-like vacuoles in an early stage of infection. This study suggests a hierarchical autophagy mechanism activated by intracellular bacterial pathogens.

Abstract
Patients often experience temporary difficulty in masticating during the period immediately following dental treatment. The purpose of this study was to investigate subjectively assessed satisfaction with a specially designed diet for such patients by means of a questionnaire. These "easy-to-eat meals" were planned and provided by this hospital in Japan, and comprised a combination of commercially available and nutritionally rich soft foods, jellied foods, drinks, and other items. The patients were required to commence consuming them immediately following dental treatment. The questionnaire contained 6 categories -Satisfaction, Taste, Meal completion, Convenience, Reduction in discomfort, and Likelihood of reuse - to be evaluated on a 10-cm visual analog scale (VAS). The overall response was positive in all 41 completed questionnaires, with an overall score of 6 or higher for every category. Orthodontics achieved the highest VAS score in every category, followed by oral implantology, prosthodontics, and conservative Original Article doi:10.2209/tdcpublication.2018-0055 dentistry. A correlation was observed between Satisfaction and each of the 5 remaining questionnaire categories (Taste: |r|=0.70, p≤0.00; Meal completion: |r|=0.60, p≤0.00; Convenience: |r|=0.56, p≤0.00; Reduction in discomfort: |r|=0.48, p=0.00; and Likelihood of reuse: |r|=0.79, p≤0.00). An acceptable level of convenience was obtained with these meals, as they were reported to be useful during the period immediately following treatment, when eating out or preparing meals was physically and/or psychologically difficult.

Abstract
OBJECTIVE Vertical jump height and oral function affect the general muscle condition. This study aimed to evaluate the association between vertical jump height and oral function among healthy older individuals. BASIC RESEARCH DESIGN Cross-sectional analytic study. PARTICIPANTS 231 independent older people (mean age, 74.4 ± 5.6 years) who participated in the Kyoto Elders Physical Fitness Measurement Research Project. Individuals with partial or complete edentulousness who did not use a prosthetic device or complained of oral/maxillofacial pain were excluded from the study. INTERVENTIONS Grip strength was measured using a Smedley Hand Dynamometer. To measure masticatory performance, the participants were instructed to chew a gummy jelly on their habitual chewing side (left or right) for 20 s. Occlusal force, contact area, and pressure were also assessed. MAIN OUTCOME MEASURES The outcome variable was vertical jump height. The predictor variables were physical status (age, body mass index, and grip strength), oral status (number of present teeth and denture use), and oral function (masticatory performance, occlusal force, occlusal contact area, occlusal pressure, and tongue pressure). These relationships were evaluated with univariate analysis, and then multiple regression analysis was performed with age as the covariate for each male and female participant. RESULTS Vertical jump height was significantly associated with grip strength in both men and women. Moreover, in women, it was associated with masticatory performance, occlusal force, and occlusal contact area. CONCLUSIONS Vertical jump height was closely associated with oral function among healthy older women.

Abstract
OBJECTIVE To clarify the genetic mechanisms underlying intervertebral disc degeneration (IDD), we examined the associations between single-nucleotide polymorphisms (SNPs) and indicated as coefficient of interaction term (IDD) in a general population in Japan. METHODS This was a cross-sectional study. In 1,605 participants, C2-3 to L5/S1 in the total spine magnetic resonance imaging (MRI) were evaluated using the Pfirrmann's scoring system. Disc scores of 4 and 5 were defined as IDD. Eight SNPs in eight genes associated with IDD were examined at each disc level, considering the non-genetic risk factors of age, sex, and body mass index (BMI). RESULTS The highest odds ratio was found for rs9406328 in the THBS2 gene at disc level T12-L1 (OR 1.27, 95%CI 1.05 to 1.53), and this association was strengthened after adjustment for age using logistic regression (OR 1.37, 95%CI 1.12 to 1.67). Among participants aged <50 years and 50-59, the average IDD score in those with 2 risk alleles of rs9406328 was markedly higher than in those with 0 or 1 risk allele, and the difference is much wider than the elderly participants. It indicates the genetic effect of rs9406328 is stronger in the younger age groups. Finally, multiple linear regression analyses of the association between rs9406328 and IDD, adjusted for age, sex, and BMI at each disc level, showed a statistical interaction between age and the number of risk alleles at C7-T1, T3-4 and T4-T5 as well as T12-L1. CONCLUSION CONCLUSION: The association between rs9406328 in THBS2 and IDD was replicated. The contributions of genetic and environmental factors to IDD differed by disc level.

The crystallization behaviors of safflower and olive oils were investigated according to changes in volume and transmitted light intensity during isothermal storage at low temperature. The changes between the oils were significantly different even though their fatty acid compositions were similar, with oleic acid accounting for more than 75% (w/w) of the total oil. It was expected that minor components with high melting points would affect the crystallization behaviors of these oils. The crystallization processes of the oils were then analyzed using a kinetic model in which the oil crystallizes through two different processes. It is suggested that although the crystallization behaviors were apparently different, the crystallization mechanisms of these oils are essentially the same.

Abstract
The aim of this study was to compare the safety of tooth extraction in patients receiving direct oral anticoagulants (DOACs) or warfarin without cessation of their antithrombotic treatment. This prospective observational study included 367 patients undergoing tooth extraction (119 receiving DOACs and 248 receiving warfarin). All extractions in DOAC patients were performed 6-7h after taking DOACs in consideration of the half-life in blood under continued antithrombotic treatment. To examine the potential postoperative bleeding risk related to the time of extraction and the drug concentration of blood, activated partial thromboplastin time (APTT) in dabigatran and prothrombin time (PT) in rivaroxaban were measured three times after administration. A total of 390 tooth extractions were performed: 128 in the DOAC patients and 262 in warfarin patients. Postoperative bleeding occurred in four extractions (3.1%) in the DOAC group and in 23 (8.8%) in the warfarin group. There was no statistically significant difference between the two groups (odds ratio: 2.362, 95% confidence interval (CI) 0.819-6.815, p=0.112). APTT and PT prolongation in almost all cases decreased with time after taking the medicine. Our findings suggest that interruption of DOAC therapy is not necessary for tooth extraction if the procedure is performed at least 6h after the last dose.

Abstract
High precision measurements of the ground state hyperfine structure (HFS) of muonium is a stringent tool for testing bound-state quantum electrodynamics (QED) theory, determining fundamental constants of the muon magnetic moment and mass, and searches for new physics. Muonium is the most suitable system to test QED because both theoretical and experimental values can be precisely determined. Previous measurements were performed decades ago at LAMPF with uncertainties mostly dominated by statistical errors. At the J-PARC Muon Science Facility (MUSE), the MuSEUM collaboration is planning complementary measurements of muonium HFS both at zero and high magnetic field. The new high-intensity muon beam that will soon be available at H-Line will provide an opportunity to improve the precision of these measurements by one order of magnitude. An overview of the different aspects of these new muonium HFS measurements, the current status of the preparation for high-field measurements, and the latest results at zero field are presented.
