Abstract
Coronary artery stenosis is often advanced by the time coronary computed tomography angiography (CCTA). Statins are the most important anti-lipidemic medication for improving the prognosis of coronary artery disease (CAD) patients. Although lipid-lowering therapy using statins appears to have been established as a method for preventing CAD, there remains the problem that CAD cannot be completely suppressed. In this study, we investigated whether pre-treatment with statin could significantly inhibit the onset of CAD when patients received CCTA for screening of CAD. The subjects were 1164 patients who underwent CCTA as screening for CAD. CAD was diagnosed when 50% or more coronary stenosis was present in the coronary arteries. Patient backgrounds were investigated by age, gender, body mass index, coronary risk factors [family history of cardiovascular diseases, smoking history, hypertension (HTN), diabetes mellitus (DM), dyslipidemia, chronic kidney disease (CKD) or metabolic sydrome] and medications. Patients were classified into two groups according to the presence or absence of statin pre-administration during CCTA [statin (-) group (n = 804) and (+) group (n = 360)]. Compared with the statin (-) group, the statin (+) group was significantly older and had higher rates of family history, HTN, and DM. The statin (+) group had a significantly higher % CAD than the statin (-) group. Serum levels of low-density lipoprotein cholesterol (LDL-C) were significantly lower in the statin (+) group than in the statin (-) group. There was no significant difference in either high-density lipoprotein cholesterol levels or triglyceride levels between the two groups. Age, male gender, HTN, DM and pre-treatment with statin were all associated with CAD (+) in all patients. In addition, factors that contributed to CAD (+) in the statin (-) group were age, male gender, and DM, and factors that contributed to CAD (+) in the statin (+) group were age, smoking, HTN and % maximum dose of statin. At the time of CCTA, the statin (+) group had a high rate of CAD and coronary artery stenosis progressed despite a reduction of LDL-C levels. To prevent the onset of CAD, in addition to strict control of other coronary risk factors (HTN etc.), further LDL cholesterol-lowering therapy may be necessary.

Abstract
BACKGROUND Locally recurrent rectal cancer (LRRC) involving the upper sacrum is typically incurable, and palliative treatment is the only option for most patients, resulting in a poor prognosis and reduced quality of life. Carbon ion radiotherapy (CIRT) has emerged as a promising modality for treating LRRC. This report presents a case of LRRC with sacral involvement that was managed via multidisciplinary therapy incorporating CIRT. CASE PRESENTATION A 55-year-old male was diagnosed with an anastomotic recurrence of rectal cancer 15 months after undergoing anterior resection. Computed tomography (CT) suggested that the lesion was at an anastomosis site and broadly adherent to the upper sacrum, and colonoscopy confirmed the diagnosis of LRRC. Histopathological examination of the biopsy specimens revealed adenocarcinoma cells and that lesion was genetically RAS-wild. Induction chemotherapy with mFOLFOX6 and panitumumab was used as the first treatment. The recurrent lesion shrank and no signs of distant metastasis were observed after 11 cycles, although the range of the lesions attached to the sacrum remained unchanged. Therefore, we provided CIRT for this inoperable lesion and prophylactically removed the radiation-exposed bowel including the recurrent lesion, because radiation-induced ulcers can cause bleeding and perforation. Despite the presence of considerable fibrosis in the irradiated region, the operation was successful and the postoperative course had no untoward incidents. He is still recurrence-free 24 months following surgery, despite the lack of adjuvant chemotherapy. This is the first report of CIRT followed by CIRT-irradiated bowel removal for an unresectable anastomosis recurrent lesion. CONCLUSIONS The clinical course of this case suggests that CIRT could be a potentially effective therapeutic option for LRRC involving the bowel, as long as the prophylactic removal of the irradiated bowel is performed at the optimal time. Further research involving larger sample sizes is warranted to validate the findings and conclusions of this case report.

Abstract
BACKGROUND Hyperuricemia (HU) and hypertension (HTN) contribute to atherosclerotic cardiovascular disease, and both are also involved in the onset and development of atrial fibrillation (AF). OBJECTIVE In the present study, we investigated the association between risk factors for atherosclerosis [including HU, HTN, blood pressure and serum uric acid (UA) levels] and paroxysmal atrial fibrillation (Paro-AF) or persistent atrial fibrillation (Pers-AF) in patients who underwent coronary computed tomography angiography (CCTA). METHODS We enrolled 263 patients from the Fukuoka University-CCTA-AF (FU-CCTA-AF Registry) who underwent CCTA prior to AF ablation therapy. AF was classified as either Paro-AF (≤ 7 days) or Pers-AF (> 7 days). HU was diagnosed by a serum UA level > 7.0 mg/dl, and coronary artery disease (CAD) was diagnosed when CCTA results showed ≥ 50% significant coronary artery stenosis. The number of significantly diseased coronary artery vessels (VD), the Gensini score and the coronary artery calcification score (CACS) were measured. Left atrial morphology was also evaluated. RESULTS Diastolic blood pressure and HbA1c in the Pers-AF group were significantly higher than those in the Paro-AF group. The Pers-AF group showed a significantly higher prevalence of HU and higher UA levels than the Paro-AF group. In a multivariate logistic regression analysis, HU was an independent associated factor to Pers-AF (odds ratio: 2.023, 95% confidence interval: 1.055-3.881, p = 0.034), while HTN was not. CONCLUSION In patients with AF, HU is associated with Pers-AF.

Abstract
Background Left ventricular mass (LVM) is a critical marker of future cardiovascular risk. We determined the association between LVM measured by coronary computed tomography angiography (CCTA) and the presence of coronary artery disease (CAD) or peripheral artery disease (PAD) in patients who had undergone CCTA for screening of CAD. Methods We enrolled 1,307 consecutive patients (66 ± 12 years old, 49% males) who underwent CCTA for screening of CAD at the Fukuoka University Hospital (FU-CCTA registry), and either were clinically suspected of having CAD or had at least one cardiovascular risk factor. Patients with coronary stenosis of ≥ 50% by CCTA were diagnosed as CAD. Patients with an ankle brachial pressure index < 0.9 or who had already been diagnosed with PAD were considered to have PAD. Left ventricular mass index (LVMI), left ventricular ejection fraction (LVEF), end-diastolic volume (EDV) and end-systolic volume (ESV) were measured. The patients were divided into CAD (-) and CAD (+) or PAD (-) and PAD (+) groups. Results The prevalences of CAD and PAD in all patients were 50% and 4.8%, respectively. Age, %males, %hypertension (HTN), %dyslipidemia (DL), %diabetes mellitus (DM), %smoking and %chronic kidney disease in the CAD (+) group were significantly higher than those in the CAD (-) group. Age, %males, %HTN, %DM and %smoking in the PAD (+) group were significantly higher than those in the PAD (-) group. CAD was independently associated with LVMI (odds ratio (OR): 1.01, 95% confidence interval (CI): 1.01 - 1.02, P < 0.01) in addition to age, male, HTN, DL, DM, and smoking. PAD was also independently associated with LVMI (OR: 1.01, 95% CI: 1.0 - 1.02, P = 0.018) in addition to age, DM, and smoking. Conclusions LVMI determined by CCTA may be useful for predicting atherosclerotic cardiovascular diseases including both CAD and PAD, although there were considerable differences between %CAD and %PAD in all patients.

Abstract
The liver fibrosis score reflects the degree of hepatic scarring and has been reported to be associated with cardiovascular disease. Using a coronary artery computed tomography angiography registry at the Fukuoka University Hospital (FU-CCTA registry), we investigated the association between major adverse cardiovascular events (MACEs) and the liver fibrosis score (fibrosis-4 index (FIB-4I)) in 612 patients who underwent CCTA to screen for coronary artery disease and performed a prognosis survey for up to 5 years. The primary endpoint was MACEs (all-cause mortality, acute myocardial infarction, ischemic stroke, coronary revascularization). FIB-4I in all patients and in patients with hypertension (HTN) was significantly higher in the MACE group than in the non-MACE group. The event-free survival rate of MACEs targeting only patients with HTN was significantly lower in patients with a high risk of liver fibrosis (FIB-4I values of 2.67 or higher) than in those with a low or intermediate risk (less than 2.67). However, no significant difference was observed in all patients or in patients without HTN. Finally, FIB-4I and body mass index were independent factors associated with MACEs in patients with HTN. In conclusion, the liver fibrosis score may be an independent predictor of MACEs in hypertensive patients undergoing CCTA.

Abstract
Liver fibrosis scores, indicative of hepatic scarring, have recently been linked to coronary artery disease (CAD). We investigated the association between CAD and the fibrosis-4 index (FIB-4I) in patients who underwent coronary computed tomography angiography (CCTA). This study included 1244 patients who were clinically suspected of having CAD. The presence or absence of CAD was the primary endpoint. FIB-4I was higher in the CAD group than in the non-CAD group (1.95 ± 1.21 versus [vs.] 1.65 ± 1.22, p < 0.001). FIB-4I was also higher in the hypertension (HTN) group than in the non-HTN group (1.90 ± 1.32 vs. 1.60 ± 0.98, p < 0.001). In all patients, high FIB-4I (≥2.67) was a predictor of presence of CAD (odds ratio [OR]: 1.92, 95% confidence interval [CI]: 1.30-2.83, p = 0.001), and low FIB-4I (≤1.29) was proven to be a predictor of absence of CAD (OR: 0.65, 95% CI: 0.48-0.88, p = 0.006). In the HTN group, high and low FIB-4I levels, were found to be predictors for CAD (OR: 2.01, 95% CI: 1.26-3.21, p < 0.001 and OR: 0.65, 95% CI: 0.45-0.94, p < 0.022, respectively), in particular. FIB-4I may serve as a diagnostic indicator of the presence or absence of CAD in hypertensive patients undergoing CCTA.

Background From the Fukuoka University Coronary Computed Tomography Angiography (FU-CCTA) registry, we present major adverse cardiovascular events (MACEs) in hypertensive patients who have undergone CCTA, and the association between MACEs and the Gensini score of coronary arteries or the coronary artery calcification (CAC) score. Methods Of the patients who underwent CCTA for coronary artery disease (CAD) screening at Fukuoka University Hospital, 318 hypertensive patients who had at least one cardiovascular risk factor or suspected CAD were enrolled. The patients were divided into two groups: MACEs and non-MACEs groups. The severity of atherosclerosis of coronary arteries was assessed by the Gensini score. The CAC score was also defined by computed tomography (CT) images at the time of CCTA. A primary endpoint was MACEs (all-cause death, ischemic stroke, acute myocardial infarction, coronary revascularization). The patients were followed for up to 5 years. Results The patients were 68 ± 10 years, and 50% were males. The percentages of smoking, dyslipidemia, diabetes, and chronic kidney disease were 39%, 70%, 26% and 37%, respectively. The %males, %smoking, CAC score and Gensini score in the MACEs group were significantly higher than those in the non-MACEs group. On the other hand, the differences in age, dyslipidemia, diabetes, or chronic kidney disease between the groups were not seen. A multivariate analysis was performed regarding the presence or absence of MACE by logistic regression analysis of the CAC score or Gensini score in addition to conventional risk factors as independent variables. A Cox regression analysis revealed significant relationships for both the CAC score (P = 0.043) and the Gensini score (P = 0.008). Conclusions The CAC score and the Gensini score could predict MACEs in hypertensive patients who have undergone CCTA.

Abstract
Chronic vasculitis is considered to be associated with future cardiovascular events. Here, we present major cardiovascular events (MACEs) in patients who underwent coronary computed tomography angiography (CCTA) for screening for coronary artery disease (CAD), and the association between MACEs and the inflammation marker pentraxin (PTX)-3 or highly sensitive C-reactive protein (hsCRP). The patients who underwent CCTA for the purpose of screening for CAD at Fukuoka University Hospital (FU-CCTA registry), 456 patients with suspected CAD or at least one cardiovascular risk factor were followed for up to 5 years. The levels of PTX-3 and hsCRP in blood were measured at the time of CCTA, and the patients were divided into two groups according to the presence (MACEs group) or absence (non-MACEs group) of MACEs. There were no differences in PTX-3 or hsCRP between the MACEs (-) and MACEs ( +) groups in all patients. A multivariate analysis related to the presence or absence of MACEs by logistic regression analysis of inflammation factors (PTX-3 and hsCRP) in addition to conventional risk factors as independent variables was performed. PTX-3 was a predictor of MACEs in males, whereas smoking, but not PTX-3, was a predictor of MACEs in females. PTX-3 could be a predictor of MACEs in males, but not females.

Abstract
Current deep learning-based cerebral aneurysm detection demonstrates high sensitivity, but produces numerous false-positives (FPs), which hampers clinical application of automated detection systems for time-of-flight magnetic resonance angiography. To reduce FPs while maintaining high sensitivity, we developed a multidimensional convolutional neural network (MD-CNN) designed to unite planar and stereoscopic information about aneurysms. This retrospective study enrolled time-of-flight magnetic resonance angiography images of cerebral aneurysms from three institutions from June 2006 to April 2019. In the internal test, 80% of the entire data set was used for model training and 20% for the test, while for the external tests, data from different pairs of the three institutions were used for training and the remaining one for testing. Images containing aneurysms > 15 mm and images without aneurysms were excluded. Three deep learning models [planar information-only (2D-CNN), stereoscopic information-only (3D-CNN), and multidimensional information (MD-CNN)] were trained to classify whether the voxels contained aneurysms, and they were evaluated on each test. The performance of each model was assessed using free-response operating characteristic curves. In total, 732 aneurysms (5.9 ± 2.5 mm) of 559 cases (327, 120, and 112 from institutes A, B, and C; 469 and 263 for 1.5T and 3.0T MRI) were included in this study. In the internal test, the highest sensitivities were 80.4, 87.4, and 82.5%, and the FPs were 6.1, 7.1, and 5.0 FPs/case at a fixed sensitivity of 80% for the 2D-CNN, 3D-CNN, and MD-CNN, respectively. In the external test, the highest sensitivities were 82.1, 86.5, and 89.1%, and 5.9, 7.4, and 4.2 FPs/cases for them, respectively. MD-CNN was a new approach to maintain sensitivity and reduce the FPs simultaneously.

Abstract
Background:
Obesity is a critical cardiovascular risk factor that has been defined in terms of body mass index (BMI), abdominal circumference (AC), and fat area. In this study, we examined which markers of obesity are most closely associated with major adverse cardiovascular events (MACE). Methods and Results:
This prospective cohort study enrolled 529 consecutive patients who initially underwent coronary computed tomography angiography for screening of coronary atherosclerosis at Fukuoka University Hospital (FU-CCTA Registry) and either were clinically suspected of having coronary artery disease (CAD) or had at least 1 cardiovascular risk factor with a follow-up of up to 5 years. Measurements of subcutaneous fat area (SFA), visceral fat area (VFA), and AC were quantified using multidetector row computed tomography. The primary endpoint was MACE. SFA and the SFA to VFA ratio (SFA/VFA) were significantly lower in the MACE than non-MACE group. SFA, AC, BMI, and SFA/VFA were each independently associated with MACE. Receiver operating characteristic curve analysis revealed a greater area under the curve for SFA/VFA than for the other parameters. The cut-off level of SFA/VFA with the greatest sensitivity and specificity for the diagnosis of MACE was 1.45 (sensitivity 0.849, specificity 0.472). Conclusions:
Our results suggest that SFA/VFA may be a marker for evaluating the presence of MACE.

Abstract
The present study aimed to investigate the associations between high-density lipoprotein (HDL) functionality and major adverse cardiovascular events (MACE) in patients who have undergone coronary computed tomography angiography (CCTA). We performed a prospective cohort study and enrolled 151 patients who underwent CCTA and had a follow-up of up to 5 years. We measured cholesterol efflux capacity (CEC), caspase-3/7 activity and monocyte chemoattractant protein-1 (MCP-1) secretion as bioassays of HDL functionality. The patients were divided into MACE(−) (n = 138) and MACE(+) (n = 13) groups. While there was no significant difference in %CEC, caspase-3/7 activity or MCP-1 secretion between the MACE(−) and MACE(+) groups, total CEC and HDL cholesterol (HDL-C) in the MACE(+) group were significantly lower than those in the MACE(−) group. Total CEC was correlated with HDL-C. A receiver-operating characteristic curve analysis showed that there was no significant difference between the areas under the curves for total CEC and HDL-C. In conclusion, total CEC in addition to HDL-C, but not %CEC, was associated with the presence of MACE. On the other hand, HDL functionality with regard to anti-inflammatory and anti-apoptosis effects was not associated with MACE.

Abstract
It is unclear whether higher levels of serum high-density lipoprotein cholesterol (HDL-C) prevent major adverse cardiovascular events (MACE). We prospectively evaluated 501 patients who had undergone coronary computed tomography angiography at Fukuoka University Hospital and either were clinically suspected of having coronary artery disease (CAD) or had at least one cardiovascular risk factor with a follow-up of up to 5 years. The primary endpoint was MACE (cardiovascular death, ischemic stroke, acute myocardial infarction and coronary revascularization). The patients were divided into tertiles according to the HDL-C level: 47 mg/dl ≥ HDL-C level [n = 167, lower HDL-C level (L-HDL)], 58 mg/dl ≥ HDL-C level ≥ 48 mg/dl [n = 167, middle HDL-C level (M-HDL)] and HDL-C level ≥ 59 mg/dl [n = 167, higher HDL-C level (H-HDL)] groups. There were significant differences in %CAD among the L-HDL, M-HDL and H-HDL groups. Unexpectedly, there was no difference in %MACE between M-HDL and H-HDL, although %MACE in M-HDL was significantly lower than that in L-HDL (p < 0.05). By a multivariate logistic regression analysis, MACE in H-HDL-C was independently associated with diabetes mellitus (DM) (p = 0.03). A Kaplan-Meier curve according to the HDL subgroup indicated that M-HDL, not H-HDL, enjoyed the greatest freedom from MACE among the 3 groups (log-rank test p = 0.047). Finally, the results of a Cox regression model indicated that L-HDL and H-HDL had significantly higher risk of MACE than M-HDL. In conclusions, patients with middle HDL-C levels, not higher HDL-C levels, showed the greatest freedom from MACE. Patients with higher HDL-C levels need to be strictly managed for DM to prevent MACE.

Abstract
Background Sodium-glucose co-transporter 2 inhibitor (SGLT2i) and dipeptidyl peptidase 4 inhibitor (DPP4i) are oral hypoglycemic agents. Although SGLT2i has been shown having the beneficial effects on heart failure in basic and clinical studies, the combined effects of SGLT2i and DPP4i have not been established well. We investigated the effects of SGLT2i and DPP4i against diabetes mice model of myocardial ischemia-reperfusion injury. Methods Streptozotocin-induced diabetic C57BL/6J mice were divided into control (vehicle), empagliflozin (30 mg/kg/day), linagliptin (3 mg/kg/day) and combination (30 mg/kg/day and 3 mg/kg/day, respectively) groups. After 7 days of drug administration, 30 min of myocardial ischemia was performed. We investigated body weight, heart weight, blood glucose, and cardiac functions by pressure-volume Millar catheter followed by 28 days of additional drug administration. Results Blood glucose levels, body weight, and heart weight were not significantly different between the groups. In Millar catheter analysis, left ventricular volume at the peak left ventricular ejection rate which is one of the cardiac systolic parameters in combination group was significantly preserved than that in control (P = 0.036). The cardiac index in the combination group tended to be preserved compared to that in the control (P = 0.06). The pathological fibrotic area in the left ventricle in the combination group also tended to be smaller (P = 0.08). Conclusions Combination therapy with linagliptin and empagliflozin preserved cardiac systolic function on the diabetes mice model of myocardial ischemia-reperfusion injury independent of blood glucose levels.

Abstract
Background Although the Japan Atherosclerosis Society Guidelines 2017 recommend lower levels of low-density lipoprotein cholesterol (LDL-C, < 70 mg/dL or ≤ 100 mg/dL) to prevent secondary cardiovascular events, we cannot conclude that a low level of LDL-C prevents primary cardiovascular events in patients with suspected coronary artery disease (CAD). Methods We registered 1,016 patients who were clinically suspected to have CAD and who underwent coronary computed tomography angiography (CCTA) for screening of coronary atherosclerosis. We excluded 350 patients who were receiving anti-lipidemic therapies and finally analyzed 666 patients. The patients were divided into three groups according to the LDL-C level: < 70 mg/dL (n = 25, Low LDL-C), 70 - 99 mg/dL (n = 141, Middle LDL-C), and ≥ 100 mg/dL (n = 500, High LDL-C). A ≥ 50% coronary stenosis was initially diagnosed as CAD, and the number of significantly stenosed coronary vessels (VD), Gensini score and coronary artery calcification (CAC) score were quantified. Results There were no significant differences in age, high-density lipoprotein cholesterol, rates of hypertension, hemoglobin A1c, blood sugar or systolic blood pressure among the Low, Middle and High LDL-C groups. On the other hand, there were significant differences in rates of males, smoking, dyslipidemia and diabetes, diastolic blood pressure and triglyceride among the groups. The prevalence of CAD values in the Low, Middle and High LDL-C groups were similar, at 52%, 47%, and 46%, respectively. In addition, there were no significant differences in the number of VD, Gensini score or CAC score among the Low LDL-C, Middle LDL-C and High LDL-C groups. Conclusions We showed that the level of LDL-C was not associated with the presence or severity of CAD, which indicates that we need to screen by CCTA to prevent primary coronary events even if patients without anti-lipidemic therapies show low levels of LDL-C.

Abstract
We analyzed whether smoking was associated with major adverse cardiovascular events (MACE) and the progression of coronary atherosclerosis as assessed by coronary computed tomography angiography (CCTA) as screening for coronary artery disease (CAD). We enrolled 443 patients who had all undergone CCTA and either were clinically suspected of having CAD or had at least one cardiovascular risk factor. We divided the patients into smoking (past and current smoker) and non-smoking groups and into males and females, and evaluated the presence of CAD, severity of coronary atherosclerosis and MACE (cardiovascular death, ischemic stroke, acute myocardial infarction and coronary revascularization) with a follow-up of up to 5 years. %CAD and the severity of coronary atherosclerosis in the smoking group were significantly higher than those in the non-smoking group. %MACE in males and smokers were significantly higher than those in females and non-smokers, respectively. Interestingly, Kaplan-Meier curves also showed that female non-smokers enjoyed significantly greater freedom from MACE than female smokers (p = 0.007), whereas there was no significant difference in freedom from MACE between male non-smokers and male smokers (p = 0.984). Although there were no significant predictors of MACE in all patients according to a multiple logistic regression analysis, smoking was useful for predicting MACE in females, but not males. In conclusion, smoking was significantly associated with MACE in females, but not males, who underwent CCTA as screening for CAD.

Abstract
Background Hypertensive left ventricular hypertrophy is associated with the risk of heart failure, coronary heart disease and cerebrovascular disease. Although sacubitril/valsartan (SAC/VAL), a first-in-class angiotensin receptor neprilysin inhibitor, reduces the risks of death and hospitalization for patients with heart failure, its mechanism of action is not fully understood. We hypothesized that SAC/VAL is superior to other conventional drugs in reducing cardiac hypertrophy. Methods Male C57BL/6J mice were implanted with an osmotic pump containing angiotensin II (Ang II). After 7 days of Ang II infusion, mice were also treated with either SAC/VAL, valsartan, enalapril or vehicle alone each day for 2 weeks. Blood pressure measurement was done weekly, and echocardiography was performed before and 3 weeks after infusion of Ang II. Histological analyses were done using extracted heart to investigate cardiac hypertrophy and fibrosis. Results Ang II markedly elevated blood pressures in all of the treatment groups, and there were no differences in the degree of blood pressure reduction among the SAC/VAL-, valsartan- and enalapril-treated groups. Echocardiography showed that SAC/VAL significantly suppressed the increase in left ventricular (LV) wall thickness and tended to decrease LV mass. In a histological analysis, SAC/VAL inhibited Ang II-induced cardiomyocyte hypertrophy, and individual cardiomyocytes in the SAC/VAL group were smaller than those in the valsartan and enalapril groups. Although previous studies using animal models of heart failure have indicated that SAC/VAL attenuates cardiac fibrosis, we found no supporting evidence in this setting. Conclusions SAC/VAL, valsartan and enalapril all attenuated cardiomyocyte hypertrophy in a mouse model of Ang II-induced cardiac hypertrophy. Of note, SAC/VAL most strongly suppressed hypertrophy in spite of similar blood pressure-lowering effects as valsartan and enalapril. The present study suggests that SAC/VAL may have a beneficial effect on the early stage of hypertensive heart disease.

Abstract
Background Although a recent study in a Japanese cohort indicated that extremely high-density lipoprotein cholesterol (HDL-C, ≥ 90 mg/dL) had an adverse effect on atherosclerotic cardiovascular disease mortality, we could not conclude that high levels of HDL-C were associated with the presence or severity of coronary artery disease (CAD). Methods We enrolled 1,016 patients who were clinically suspected to have CAD and who underwent coronary computed tomography angiography (CCTA). The number of significantly stenosed coronary vessels (vessel disease (VD), ≥ 50% coronary stenosis is diagnosed as CAD) and the Gensini score were quantified using CCTA, and the lipid profile was measured. The patients were divided into four groups according to the HDL-C level: < 40 mg/dL (n = 115, low), 40 - 59 mg/dL (n = 530, normal), 60 - 89 mg/dL (n = 335, high) and ≥ 90 mg/dL (n = 36, very-high). Results The percentage (%) of CAD in the low, normal, high and very-high groups was 69%, 55%, 42% and 25%, respectively (P for trend < 0.01). The Gensini score in the low, normal, high and very-high groups was 20 ± 25, 12 ± 16, 8 ± 12 and 4 ± 6, respectively (P for trend < 0.01). The very-high group showed the lowest triglyceride (TG) levels among the four groups. There were no significant differences in the level of low-density lipoprotein cholesterol or % use of statin among the four groups. Finally, the presence of CAD was independently associated with a low level of HDL-C, in addition to age, male, high systolic blood pressure and hemoglobin A1c, but not TG, by a multivariate logistic regression analysis. Conclusions High levels of HDL-C at the time of CCTA for screening were associated with a reduced presence and severity of CAD.

Abstract
Background The coronary artery calcification score (CACS) is a good marker of future cardiovascular risk. We determined the association between the CACS and the prognosis in patients who have undergone coronary computed tomography angiography (CCTA). Methods We performed a prospective cohort study and enrolled 502 consecutive patients who underwent CCTA for screening of coronary artery disease (CAD) at Fukuoka University Hospital (FU-CCTA Registry) and either were clinically suspected of having CAD or had at least one cardiovascular risk factor with a follow-up of up to 5 years. The patients were divided into CACS = 0 and CACS > 0 groups. Using CCTA, ≥ 50% coronary stenosis was diagnosed as CAD, and the number of significantly stenosed coronary vessels (VD), Gensini score and CACS were quantified. The primary endpoint was major adverse cardiovascular events (MACE: cardiovascular death, ischemic stroke, acute myocardial infarction and coronary revascularization). Results %CAD, the number of VD and the Gensini score in the CACS = 0 group were significantly lower than those in the CACS > 0 group. %MACE in the CACS = 0 group was also significantly lower than that in the CACS > 0 group. Kaplan-Meier curves indicated that the CACS = 0 group showed significantly greater freedom from MACE than the CACS > 0 group (P = 0.008). Finally, only CACS = 0 was independently associated with MACE (odd ratio: 0.41, 95% confidence interval: 0.17 - 0.97, P = 0.041). Conclusions A CACS of 0 in patients who underwent CCTA was associated with a good prognosis.

Abstract
A 65-year-old man was followed for his coronary conditions using 320-multi detector row computed tomography (MDCT) for 30 months. He had soft plaque in the right coronary artery (RCA) [mean density of plaque was 22 hounsfield units (HU)]. His initial serum low-density lipoprotein cholesterol (LDL-C) was 72 mg/dL. After 30 months, his serum LDL-C was 26 mg/dL under 5.0 mg/day rosuvastatin and evolocumab 140 mg/2 weeks. MDCT showed a regression of the plaque in the RCA and the plaque density was 114 HU (intermediate plaque). In conclusion, intensive lipid-lowering therapy with evolocumab induced the regression and stabilization of coronary vulnerable plaque.

Abstract
The associations between the presence and severity of coronary artery disease (CAD) and measurements of the psoas major muscle (PMM) as assessed by multidetector row coronary computed tomography angiography (MDCT) are not known.We enrolled 793 patients who were clinically suspected to have CAD or had at least one cardiac risk factor and had undergone MDCT. The number of significantly stenosed coronary vessels (VD) and measurements of the PMM index (PMMI) were determined using MDCT.PMMI in the CAD group was significantly lower than that in the non-CAD group in males, but not females. In addition, the levels of PMMI tended to increase as the number of VD decreased in males. When male patients were divided into 2 groups according to median value of age, that is, relatively younger (53.4 ± 9.2 years) and older (72.6 ± 5.7 years) groups, the presence of CAD was independently associated with PMMI in the younger group by a multiple logistic regression analysis. The cut-off level of PMMI that gave the greatest sensitivity and specificity for the diagnosis of CAD in younger males was 8.3 cm/m (sensitivity 0.441, specificity 0.752).In conclusion, PMMI may be an imaging marker for evaluating the presence and/or severity of CAD in males, and particularly in the non-elderly.

Abstract
Lymphaticovenular anastomosis (LVA) using supermicrosurgical techniques is effective for treating and preventing progression of lymphedema. We analyzed the influence of pregnancy on LVA in five patients from a total 2179 LVA cases. Previous studies offer conflicting reports on whether pregnancy worsens pre-existing lymphedema. This is the first report on the influence of pregnancy on lower limb lymphedema previously treated by multisite LVA (mLVA). Five patients with primary (n=4) and secondary (n=1) lower leg lymphedema were analyzed for this study. Patient age ranged from 18 to 31 (average 22.6) years old with 4 right and 1 left extremities involved. Duration of symptoms ranged from one to 19 (average 7.4) years and the periods of compression therapy were from 1 to 19 years (6.6 years). Four patients had single pregnancies and one patient was multiparous with 3 pregnancies. Final follow-up ranged from 5.8 to 18 years (average 8.9 years) after the primary mLVA. All patients had normal pregnancy, birth, and no serious complications after surgeries. Following pregnancy three patients had complete functional recovery (limb volume reduction and no compression requirement), one with functional improvement (limb volume reduction but required compression), and one with no change in symptoms (not worse and continued need for compression). There were no occurrences of infection following pregnancy. Based on this case series, it is suggested that pregnancy does not worsen the pre-existing lymphedema in patients who had previously undergone mLVA. Further studies with larger number of patients are needed to confirm these results.

Abstract
A 37-year-old woman developed deep venous thrombosis (DVT) of the left lower extremity at 8 weeks of gestation during her second pregnancy. There was no personal or family history of thrombosis. She received intravenous heparin, but heparin resistance was noted. The plasma antithrombin activity decreased to 45% in the acute phase, and it remained low postpartum. Her mother also had low plasma antithrombin activity (46%), and genetic testing revealed a heterozygous SERPINC1 mutation. Even without a family history of thrombosis, we should suspect hereditary antithrombin deficiency in patients with initial DVT and perform thorough investigation.

Abstract
Background The combination of ezetimibe with statin therapy reduced cardiovascular events compared to statin monotherapy in IMPROVEIT study, and ezetimibe monotherapy attenuated atherosclerosis in basic study. We previously showed ezetimibe monotherapy was especially effective for metabolic syndrome (MetS) patients. We investigated the effects of ezetimibe monotherapy for high-density lipoprotein cholesterol (HDL-chol) function and platelet-activating factor acetylhydrolase (PAF-AH) activity. Methods Forty-two patients who initially received ezetimibe (10 mg/day) without statin treatment for 16 weeks from January 2009 to August 2011 were enrolled. Patients were divided into MetS and non-MetS groups, and serum levels of lipids, PAF-AH, and HDL-chol efflux capacity (HDL-CEC) at baseline and after 16 weeks of treatment were investigated. Serum PAF-AH, HDL-associated PAF-AH (HDL-PAF-AH), and LDL-associated PAF-AH (LDL-PAF-AH) were measured. Results In all patients, age, the percentages of males, and body mass index were 61.0 ± 8.8 years, 59.5% and 26.3 ± 3.4 kg/m2, respectively. Total cholesterol and low-density lipoprotein cholesterol (LDL-chol) were significantly decreased by ezetimibe monotherapy. Serum PAF-AH and LDL-PAF-AH were significantly decreased by ezetimibe monotherapy, whereas HDL-PAF-AH and HDL-CEC were not. There was no difference in the results of PAF-AH and HDL-CEC between MetS and non-MetS groups. Conclusions Ezetimibe monotherapy might prevent coronary heart disease (CHD) regardless of the presence of MetS, because PAF-AH was independent risk factor for CHD.

Abstract
Regulatory T cells (Tregs) and tumour-associated macrophages (TAMs) contribute to the tumour microenvironment by inhibiting anti-tumour immune responses. This study was performed to investigate the roles of Tregs and TAMs in oral squamous cell carcinoma (OSCC) and oral epithelial precursor lesions (OEPL). The expression of Treg markers CD25 and FoxP3 and TAM markers CD163 and CD204 was investigated in 82 OSCC and 45 OEPL specimens, and their associations with clinicopathological parameters were analyzed. Correlations were found among CD25, FoxP3, CD163, and CD204 levels (P < 0.001), and these targets were up-regulated in OSCC compared to OEPL (P < 0.001). In OSCC, infiltration of Tregs and/or M2 TAMs was associated with sex and clinicopathological features, such as tumour size, nodal metastasis, tissue differentiation, stromal reaction, invasive behaviour, and invasive depth. In OEPL, CD25, FoxP3, CD163, and CD204 immunoreactivities were significantly associated with sex, postoperative recurrence, and cancerization to OSCC. This study is novel in showing that the infiltration of Tregs and M2 TAMs is significantly associated with the progression of premalignant lesions to OSCC. This suggests that these cells represent prognostic biomarkers for premalignant lesion progression and that immunotherapeutic approaches to control Treg/M2 TAM numbers could protect against progression to malignancy.

Abstract
Continuous cell monitoring is very important for the maintenance and control of cell multiplication and differentiation. This paper presents a compact microplate reader that is able to continuously measure a 24-well microplate (6 × 4 wells) using the optical absorption measurement method. The 24-channel plate reader consisted of a spatial filter, light emitting diode light source, and color sensors and was similarly sized with the cell culture microwell plates. A spatial filter was previously fabricated by our group using silicone optical technology (SOT). This SOT-based spatial filter has an excellent noise reduction effect. Light reflection at the optical path interface can be absorbed and only forward light can be transmitted; accordingly, a larger S/N ratio than that of conventional optical systems is expected. The fabricated 24-channel plate reader permits real-time cell monitoring during cultivation on the clean bench and in cell culture conditions by incorporating the SOT spatial filter. Using the device, it was possible to continuously evaluate the concentration and pH of reagents in the 24 wells in real time. Moreover, cell activity and protein production were detectable using the device. These results suggest that the newly fabricated device is a promising tool for the evaluation of cell behaviors for cell management.

Abstract
Lymphaticovenular anastomosis (LVA) using supermicrosurgical techniques is effective for treating and preventing progression of lymphedema. We analyzed the influence of pregnancy on LVA in five patients from a total 2179 LVA cases. Previous studies offer conflicting reports on whether pregnancy worsens pre-existing lymphedema. This is the first report on the influence of pregnancy on lower limb lymphedema previously treated by multisite LVA (mLVA). Five patients with primary (n=4) and secondary (n=1) lower leg lymphedema were analyzed for this study. Patient age ranged from 18 to 31 (average 22.6) years old with 4 right and 1 left extremities involved. Duration of symptoms ranged from one to 19 (average 7.4) years and the periods of compression therapy were from 1 to 19 years (6.6 years). Four patients had single pregnancies and one patient was multiparous with 3 pregnancies. Final follow-up ranged from 5.8 to 18 years (average 8.9 years) after the primary mLVA. All patients had normal pregnancy, birth, and no serious complications after surgeries. Following pregnancy three patients had complete functional recovery (limb volume reduction and no compression requirement), one with functional improvement (limb volume reduction but required compression), and one with no change in symptoms (not worse and continued need for compression). There were no occurrences of infection following pregnancy. Based on this case series, it is suggested that pregnancy does not worsen the pre-existing lymphedema in patients who had previously undergone mLVA. Further studies with larger number of patients are needed to confirm these results.

Abstract
BACKGROUND: We hypothesized that the 5-oxo-1,2,4-oxadiazole moiety of azilsartan (AZL), which represents a small difference in the molecular structures of AZL and candesartan (CAN) [angiotensin II type 1 receptor (AT1R) blockers], may be responsible for the molecular effects of AZL. METHODS: We examined the binding affinities of AZL and CAN to AT1R, along with their ability to block receptor activity. A competition binding study, inositol phosphate (IP) production assay and extracellular signal-regulated kinase (ERK) assay were performed using wild-type (WT) and mutants AT1R-transfected cells. RESULTS: The binding affinities of CAN and AZL were reduced by > 5-fold for Y35F, W84F, R167K, K199Q and I288A compared with WT. In addition, AZL showed a > 5-fold reduction in its binding affinity to V108A. CAN and AZL exhibited > 20-fold and > 100-fold reductions in binding affinity to R167K, respectively. The loss of binding affinity of AZL to R167K was greater than that of CAN. CAN-7H exhibited a > 10-fold reduction in binding affinity to R167K compared with CAN. On the other hand, the binding affinity of AZL-7H to R167K was comparable to that of AZL. While 10-6M CAN and CAN-7H partly blocked Ang II-induced IP production in R167K, 10-6M AZL and AZL-7H did not. In addition, 10-6M CAN, but not 10-6M AZL, partly blocked Ang II-induced ERK activation in R167K. CONCLUSIONS: The interaction between 5-oxo-1,2,4-oxadiazole in AZL and Arg167 in the AT1R appears to be more important than the interaction between the tetrazole ring in CAN and Arg167.

Abstract
Background We evaluated the safety of a bolus injection of landiolol hydrochloride, an ultrashort-acting β1-selective antagonist, as a premedication prior to multidetector-row computed tomography coronary angiography (CTA). Methods The subjects consisted of 176 patients (M/F = 64:112, 67 ± 11 years) who had heart rate (HR) at rest ≥ 70 beats/min (bpm) and underwent CTA. Systolic/diastolic blood pressure (SBP/DBP) and HR were measured before and after the administration of landiolol. Results SBP/DBP and HR upon entry to the CT room were 136 ± 17/80 ± 11 mm Hg and 83 ± 10 bpm, respectively. HR was significantly reduced at the time of CTA scan (62 ± 7 bpm). Next, we divided the patients into three groups according to HR upon entry to the CT room: 70 - 79 bpm (n = 76), 80 - 89 bpm (n = 60) and ≥ 90 bpm (n = 40). HR at the time of CTA scan was significantly lower than that upon entry to the CT room in all three groups: 70 - 79 bpm (74 ± 3 bpm upon entry to the CT room to 61 ± 6 bpm at the time of CAT scan), 80 - 89 bpm (84 ± 3 to 63 ± 7 bpm) and ≥ 90 bpm (98 ± 6 to 65 ± 7 bpm). Although SBP/DBP was significantly decreased after the CTA scan (123 ± 18/72 ± 12 mm Hg), landiolol had no severe adverse events throughout CTA. Conclusion In conclusion, a bolus injection of landiolol reduced HR by about 20 bpm without any severe adverse effects. Thus, a bolus injection of landiolol hydrochloride may be a suitable pretreatment for controlling HR in CTA.

Abstract
BACKGROUND The pathophysiology of lymphoedema is poorly understood. Current treatment options include compression therapy, resection, liposuction and lymphatic microsurgery, but determining the optimal treatment approach for each patient remains challenging. OBJECTIVES We characterized skin and adipose tissue alterations in the setting of secondary lymphoedema. METHODS Morphological and histopathological evaluations were conducted for 70 specimens collected from 26 female patients with lower-extremity secondary lymphoedema following surgical intervention for gynaecological cancers. Indocyanine green lymphography was performed for each patient to assess lymphoedema severity. RESULTS Macroscopic and ultrasound findings revealed that lymphoedema adipose tissue had larger lobules of adipose tissue, with these lobules surrounded by thick collagen fibres and interstitial lymphatic fluid. In lymphoedema specimens, adipocytes displayed hypertrophic changes and more collagen fibre deposits when examined using electron microscopy, whole-mount staining and immunohistochemistry. The number of capillary lymphatic channels was also found to be increased in the dermis of lymphoedema limbs. Crown-like structures (dead adipocytes surrounded by M1 macrophages) were less frequently seen in lymphoedema samples. Flow cytometry revealed that, among the cellular components of adipose tissue, adipose-derived stem/stromal cells and M2 macrophages were decreased in number in lymphoedema adipose tissue compared with normal controls. CONCLUSIONS These findings suggest that long-term lymphatic volume overload can induce chronic tissue inflammation, progressive fibrosis, impaired homeostasis, altered remodelling of adipose tissue, impaired regenerative capacity and immunological dysfunction. Further elucidation of the pathophysiological mechanisms underlying lymphoedema will lead to more reliable therapeutic strategies.

Abstract
BACKGROUND No scoring system has ever been used to estimate the prognosis of individual tuberculosis (TB) patients. OBJECTIVE To develop and validate a tuberculosis prognostic score. METHODS This retrospective cohort study conducted in Japan comprised the development (n = 179; mean age 65.9 ± 18.8 years) and validation (n = 244; mean age 64.3 ± 20.1 years) of a tuberculosis prognostic score among patients with newly diagnosed smear-positive non-multidrug-resistant pulmonary tuberculosis without human immunodeficiency virus infection. The score (raw score) was defined by modifying a logistic regression formula using known risk factors as independent variables and in-patient death as a dependent variable. RESULTS The raw score was calculated as follows: age (years) + (oxygen requirement, 10 points) - 20 × albumin (g/dl) + (activity of daily living: independent, 0 point; semi-dependent, 5 points; totally dependent, 10 points). The raw scores were grouped into risk groups 1 (raw score < -30) to 5 (raw score ≥ 60) using 30-point intervals. Every increase in risk group was equivalent to a 7.3-fold increase in the odds ratio for in-hospital death (P < 0.001). The area under the receiver operating characteristics curve by risk group for in-patient death was 0.875 (P < 0.001). CONCLUSIONS In this study we were able to develop and validate a tuberculosis prognostic score.

Abstract
Chymase stored in mast cells activates matrix metalloproteinase (MMP)-9, which may relate to the progression of sinusoidal obstruction syndrome (SOS). We investigated the preventive effect of a chymase inhibitor, TY-51469, on monocrotaline-induced SOS in hamsters. Hamsters were orally administrated with a single dose of monocrotaline (120 mg/kg) to induce SOS. Treatment with TY-51469 (1 mg/kg per day) or placebo had started 3 days before the monocrotaline administration. Two days after the monocrotaline administration, significant increases in aspartate aminotransferase, alanine aminotransferase and total bilirubin and a significant reduction of albumin were observed in plasma, but their changes were significantly attenuated by treatment with TY-51469. The numerous hepatic necrosis areas were observed in the placebo-treated group, but the ratio of necrotic area to total area in liver had been significantly reduced by treatment with TY-51469. Both chymase activity and MMP-9 level in liver were significantly augmented in the placebo-treated group. Furthermore, tumor necrosis factor (TNF)-α level in liver was also augmented in the placebo-treated group. However, the chymase activity and levels of MMP-9 and TNF-α were significantly attenuated in the TY-51469-treated group. Until 14 days after monocrotaline administration, survival rates in the placebo- and TY-51469-treated groups were 25% and 70%, respectively, and a significant difference was observed. In conclusion, chymase inhibition by TY-51469 may prevent the accelerating of severity in monocrotaline-induced SOS in hamsters.

Abstract
High expression ratios of CD44 variant 6 (CD44 V6) in patients with metastatic pulmonary tumor were found in those with primary lesions of cancer of the colon, uterus, larynx, liver and osteosarcoma. It was clarified that patients showing expression of CD44 variant 6 likely revealed pulmonary metastasis at earlier time following operations of primary cancer (p<0.05). CD44 V6, an adhesion molecule, was a factor to participate in pulmonary metastases from various organ cancers. No significant correlation was observed in survival between patients with CD44 V6 positive versus negative tumors, except laryngeal tumor after resection of primary or metastatic lung tumor. CD44 V6 related to its invasive and further metastatic functions in metastatic lung tumor. We suggest that cancer cells expressing the CD44 molecule especially V6 may adhere to vascular endothelium and hyaluronic acid in the lung. And cancer cells without this molecule liberated from the primary focuses hardly adhere to the pulmonary tissues supposedly resulting in delayed metastases and proliferations in the pulmonary tissues.

Abstract
Tumor cell (TC) metastasis is initiated by selective adhesion of TCs to target structures such as basement membrane and endotheliaI cells (ECs), followed by transvascular migration of TCs. Variants of murine B16 melanoma having different metastatic potentials (in the order BL6 greater than or equal to F10>F1>WA4) have been characterized by the same decreasing order of cell surface G(M3) expression level, relative adhesiveness to nonactivated ECs, and relative degree of G(M3)-dependent adhesion to Gg3Cer- or LacCer-coated plates. Degree of integrin-dependent cell adhesion and adhesion to IL-1-activated ECs was similar for BL6, F10, and F1. These results suggest that metastatic potential of these B16 variants is closely dependent on relative adhesion to nonactivated ECs, which is based on G(M3)-Gg3Cer or G(M3)-LacCer interaction. This possibility has been supported by further studies showing that blocking of G(M3)-dependent melanoma adhesion by mu M-order concentrations of G(M3) or Gg3Cer in liposomes, or by sialidase treatment of melanoma cells, strongly inhibited BL6 metastasis to lung. Paragloboside or sialylparagloboside did not affect G(M3)-dependent BL6 cell adhesion and did not inhibit metastasis. Spontaneous metastasis from subcutaneously-grown tumors was significantly reduced if G(M3)- or Gg3Cer-liposomes were intravenously injected during tumor growth. Thus, blocking of TC adhesion to nonactivated ECs based on carbohydrate-carbohydrate interaction may provide effective anti-adhesion therapy against tumor progression, in analogy to the antimetastatic effect produced by blocking of integrin-dependent cell adhesion.

Abstract
Objectives The main histological change in rheumatoid arthritis (RA) is the villous proliferation of synovial lining cells, an important source of cytokines and chemokines, which are associated with inflammation. The aim of this study was to evaluate gene expression in the microdissected synovial lining cells of RA patients, using those of osteoarthritis (OA) patients as the control. Methods Samples were obtained during total joint replacement from 11 RA and five OA patients. Total RNA from the synovial lining cells was derived from selected specimens by laser microdissection (LMD) for subsequent cDNA microarray analysis. In addition, the expression of significant genes was confirmed immunohistochemically. Results The 14 519 genes detected by cDNA microarray were used to compare gene expression levels in synovial lining cells from RA with those from OA patients. Cluster analysis indicated that RA cells, including low- and high-expression subgroups, and OA cells were stored in two main clusters. The molecular activity of RA was statistically consistent with its clinical and histological activity. Expression levels of signal transducer and activator of transcription 1 (STAT1), interferon regulatory factor 1 (IRF1), and the chemokines CXCL9, CXCL10, and CCL5 were statistically significantly higher in the synovium of RA than in that of OA. Immunohistochemically, the lining synovium of RA, but not that of OA, clearly expressed STAT1, IRF1, and chemokines, as was seen in microarray analysis combined with LMD. Conclusions Our findings indicate an important role for lining synovial cells in the inflammatory and proliferative processes of RA. Further understanding of the local signalling in structural components is important in rheumatology.

Abstract
The T2K experiment observes indications of ν(μ) → ν(e) appearance in data accumulated with 1.43×10(20) protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with |Δm(23)(2)| = 2.4×10(-3) eV(2), sin(2)2θ(23) = 1 and sin(2)2θ(13) = 0, the expected number of such events is 1.5±0.3(syst). Under this hypothesis, the probability to observe six or more candidate events is 7×10(-3), equivalent to 2.5σ significance. At 90% C.L., the data are consistent with 0.03(0.04) < sin(2)2θ(13) < 0.28(0.34) for δ(CP) = 0 and a normal (inverted) hierarchy.

Abstract
AbstractStructure changes in the ferroelectric phase transitions of vinylidene fluoride-trifluoroethylene (VDF-TrFE) copolymers were investigated on the basis of a set of experimental data of WAXS, SAXS, IR and Raman measurements. An intimate relation has been clarified between the structural changes in the crystal lattice and the morphological changes. These structural changes were found to originate ultimately from the remarkable change in the molecular conformation between trans and gauche forms. In order to extract the essentially important factors governing this trans-gauche conformational change in the phase transition, the molecular dynamics calculation was carried out, giving relatively good reproduction of the observed structural changes.
