Abstract
The HIV-1 capsid is a shell that encapsulates viral RNA, and forms a conical structure by assembling oligomers of capsid (CA) proteins. Since the CA proteins are highly conserved among many strains of HIV-1, the inhibition of the CA function could be an appropriate goal for suppression of HIV-1 replication, but to date, no drug targeting CA has been developed. Hydrophobic interactions between two CA molecules through Trp184 and Met185 in the protein are known to be indispensable for conformational stabilization of the CA multimer. In our previous study, a small molecule designed by in silico screening as a dipeptide mimic of Trp184 and Met185 in the interaction site was synthesized and found to have significant anti-HIV-1 activity. In the present study, molecules with different scaffolds based on a dipeptide mimic of Trp184 and Met185 have been designed and synthesized. Their significant anti-HIV activity and their advantages compared to the previous compounds were examined. The present results should be useful in the design of novel CA-targeting anti-HIV agents.

Abstract
Potent and biostable inhibitors of the main protease (Mpro) of SARS-CoV-2 were designed and synthesized based on an active hit compound 5h (2). Our strategy was based not only on the introduction of fluorine atoms into the inhibitor molecule for an increase of binding affinity for the pocket of Mpro and cell membrane permeability but also on the replacement of the digestible amide bond by a surrogate structure to increase the biostability of the compounds. Compound 3 is highly potent and blocks SARS-CoV-2 infection in vitro without a viral breakthrough. The derivatives, which contain a thioamide surrogate in the P2-P1 amide bond of these compounds (2 and 3), showed remarkably preferable pharmacokinetics in mice compared with the corresponding parent compounds. These data show that compounds 3 and its biostable derivative 4 are potential drugs for treating COVID-19 and that replacement of the digestible amide bond by its thioamide surrogate structure is an effective method.

Abstract
Abstract
Background/Introduction
New onset of atrial fibrillation (AF) is associated with adverse short- and long-term outcomes after acute myocardial infarction (AMI), and its prediction is relevant for the risk stratification in patients with AMI. Although several risk scores were developed for AF in the general population, there is no established risk score for AF occurrence after AMI.
Purpose
To develop a risk score to predict occurrence of AF early after AMI.
Methods
We enrolled consecutive 751 patients with AMI who admitted to our hospital between April 2006 and September 2012 for the present study. New occurrence of AF was defined as AF detected during hospital stay in a patient showing normal regular sinus rhythm at admission. Parameters relevant to the occurrence of AF was selected from the clinical characteristics, physical status and blood test data at admission, and peak CK/CK-MB, by stepwise logistic regression analysis. We constructed a risk score model to predict the new occurrence of AF, using selected parameters and their logistic regression coefficients. C-statistics was determined by constructing a receiver operating characteristic curve to evaluate the accuracy of the risk score for prediction of AF occurrence.
Results
We excluded 48 patients (6.4%) who had AF at admission, and 208 patients without sufficient data at admission, and thus, the study group consisted of 459 patients (age; 65±13 years, male gender; 79.6%). New AF occurrence was observed in 72 patients (14.5%). The following 7 parameters was selected as parameters related with AF (as p<0.1); Inferior/posterior AMI, use of β blockers, use of diuretics, single vessel disease, absence of reperfusion therapy, systolic blood pressure (sBP) at admission, and smoking. One point was given to sBP>128mmHg, 2 points to absence of reperfusion, and one point to other parameters. Sum of these points was calculated as the AF risk score (Table 1). AF occurred in 27.1% of patients with ≥5 points whereas it was observed 5.2% of those with <5 points. C-statistics of the risk score was 0.75 (95% CI 0.68–0.83).
Conclusion
We developed a novel risk score to estimate the risk of AF occurrence early after AMI, which can be a useful tool for the risk stratification after AMI.

Abstract
Abstract
Background
Sleep apnea and left atrial dilatation are both risk factors for an arrhythmia recurrence after catheter ablation (CA) of atrial fibrillation (AF). Negative intrathoracic pressure fluctuations during an obstructive apnea episode may cause the left atrium to distend and stretch its wall. Whether sleep apnea is associated with left atrial dilatation in patients receiving CA of AF remains unknown.
Purpose
We sought to elucidate whether moderate or severe untreated sleep apnea was associated with left atrial dilatation in patients with AF before CA.
Methods
This study was conducted under a retrospective, single-center, observational design. The data were derived from screening tests for sleep apnea, which were routinely performed in patients scheduled to receive CA of AF in our institution. After excluding patients who were already diagnosed with sleep apnea, we enrolled 1265 consecutive patients (age 65±11 years, 27.8% females, and 46.2% of non-paroxysmal AF) who underwent both home sleep apnea testing and multidetector computed tomography (MDCT) before the CA of AF. The severity of the sleep apnea was evaluated by the apnea-hypopnea index (AHI) using a watch-type peripheral arterial tonometry. Left atrial dilatation was evaluated by the left atrial maximum volume (LA max V) using 256-slice MDCT.
Results
The age was 65±11 years, 27.8% were females, and 46.2% had non-paroxysmal AF. The mean AHI was 20.3±15.3 and LA max V 105±34 ml (R2=0.075, p<0.0001). LA dilatation was defined by larger than mean LA max V (LA max V≥105 ml). We examined an LA max V≥105 ml as a predictor. After an adjustment by an advanced age (≥65 years), non-paroxysmal AF, male sex, obesity, hypertension, and congestive heart failure, all of which were significant predictors of an LA max V≥105ml in the univariate analysis, moderate or severe sleep apnea (AHI≥15) was a significant predictor of an LA max V≥105 ml (odds ratio 1.63, 95% confidence interval 1.24–2.14, p=0.0005).
Conclusion
Among the patients scheduled to receive catheter ablation of AF, moderate or severe sleep apnea was independently associated with left atrial dilatation.

Abstract
Abstract
Background
Catheter ablation of atrial fibrillation (AFCA) is an effective treatment to develop left ventricular (LV) functional recovery. However, the degree of recovery differs between individuals due to the different extent of myocardial fibrosis and scarring.
Purpose
To examine whether pre-ablation LV wall thickness (WT) and its regional heterogeneity predict LV functional recovery after AFCA in patients with LV systolic dysfunction.
Methods
Of 3682 consecutive patients who underwent first-time AFCA between January 2012 and September 2020 in our institution, 174 (age, 63±10 years; male, 83%; ischemic cardiomyopathy, 14%) with a baseline LV ejection fraction (LVEF) of <40% were retrospectively evaluated. They were subjected to 256-slice MDCT scanning at baseline and 3 months after AFCA. Baseline WT was evaluated by 16-segment model. Mean and standard deviation (SD) of 16 regional WT were calculated in both end-systolic and end-diastolic phase.
Results
LVEF significantly improved from 30±7% to 57±17% (p<0.001) after AFCA. Increase in LVEF (delta-LVEF) was positively correlated with baseline end-diastolic WT (r=0.31, p<0.001) and negatively correlated with SD of end-systolic WT (r=−0.21, p=0.007). Independent of WT measurements, delta-LVEF was negatively correlated with LV end-diastolic volume (r=−0.42, p<0.001). We created a scoring system to predict the degree of wall motion recovery using the median value of the 3 variables; assigned 1 point each for end-diastolic WT >7.4mm, SD of end-systolic WT <1.61mm, and LV end-diastolic volume <125ml. The model successfully predicted improvement in LVEF after AFCA (0 point (N=13) vs. 1 point (N=72) vs. 2–3 point (N=89), 11±16% vs. 20±17% vs. 33±12%, p<0.001).
Conclusion
Myocardial WT and its regional heterogeneity as well as LV end-diastolic volume predicted functional recovery after AFCA in patients with reduced LVEF.

Abstract
Abstract
Background
Diagnosing heart failure with preserved ejection fraction (HFpEF) is still challenging, and the H2FPEF- and the HFA-PEFF score were proposed as simple and reliable diagnostic tools. We recently reported that the HFA-PEFF score was significantly associated with the composite endpoint of all-cause death and heart failure readmission in patients with acute decompensated HFpEF (Sotomi. Eur J Heart Fail, in press).
Purpose
To investigate the relation whether the HFA-PEFF or H2FPEF score can evaluate functional capacity in patients with HFpEF
Methods
We calculated H2FPEF score and the second step of HFA-PEFF score among the registered patients in the PURSUIT-HFpEF (Prospective, Multicenter, Observational Study of Patients with Heart Failure with Preserved Ejection Fraction) study, which is a multicenter registration of patients hospitalized for acute decompensated HFpEF. We performed 6 minute walk (6MW) test and measured NT-proBNP before discharge. We followed the study patients for median of 360 days (IQR 237–630 days) to observe the major adverse cardiovascular events (MACE; composite of death, heart failure hospitalization and stroke).
Results
We enrolled 757 patients (age 81±9 years, male gender 45%) hospitalized for acute decompensated HFpEF for the present study. The H2FPEF score was obtained in 588 (77.7%) patients and all patients had ≥2 points. The HFA-PEFF score was obtained in 615 (81.2%) patients, though global longitudinal strain was not available. We divided these patients into 3 groups based on the HFA-PEFF score (score 2 to 4, 5, and 6) or on the H2FPEF score (score 0 to 3, 4 to 5 and 6 to 8). There were a significant difference in NT-pro BNP between 3 groups based on HFA-PEFF score (p=0.01, Table 1), and patients with score 6 had significantly higher NT-proBNP than those with score 2 to 4 (p=0.02). A significant difference was observed in 6MW distance among these groups (p=0.04, Table), and those with score 6 had significantly shorter distance than those with score 2 to 4 (p=0.04). Cox proportional hazard model selected HFA-PEFF score as a significant predictor for MACE, and Kaplan-Meier survival analysis demonstrated that classification of HFA-PEFF score significantly stratified the patients' risk for MACE. On the other hand, there was no significant difference in 6MW distance among 3 groups based on H2FPEF score (p=0.53), and H2FPEF score was not an independent predictor for MCE by the Cox model analysis. Moreover, the lowest H2PEF score group had higher NT-proBNP than other 2 groups (p=0.02)
Conclusions
The HFA-PEFF score predicted functional capacity as well as prognosis in patients hospitalized for HFpEF, while the H2PEF score did not.

Background
Quantification of left ventricular (LV) dyssynchrony is of great interest for resynchronization therapy (CRT). Recently, cardiac computed tomography (CCT) is feasible for evaluation of dyssynchrony. Our aim was to assess a novel simplified approach using CCT to quantify LV dyssynchrony.
Methods
We studied 346 consecutive patients with a wide range of QRS width and ejection fractions (EF). Electrocardiogram-gated contrast-enhanced 256-slice multidetector CT (Brilliance 256 iCT, Philips Medical Systems) was performed before CRT. After CCT scan, the LV endocardial boundaries from short-axis images reconstructed at 5% increments of cardiac cycle were automatically detected, and a time from R-wave to maximal wall motion was calculated for each of the 16 standardized segments for all slices using software "Myocardial Contraction Map" (Argus, Inc Ehime, Japan). The standard deviation of all segments modified by mean heart rate (%SD) was respectively calculated as the global parameter of dyssynchrony. LVEF was also measured using MDCT.
Results
%SD was feasible in all patients, respectably. %SD was significantly different between the different QRS duration groups; narrow QRS (<120ms): 9 ± 5%, relatively wide QRS (120-150 ms): 11 ± 6%, and significantly wide QRS (>150 ms): 14 ± 7% (p <0.001). Moreover, there was significantly difference in %SD between the different morphology groups; normal: 9 ± 7%, Non-left bundle branch block (Non-LBBB): 10 ± 6%, LBBB: 17 ± 7% (p <0.001).
Conclusion
This novel simplified approach by CCT can quantify dyssynchrony in different QRS duration and morphology groups. This method has promise for clinical applications to the evaluation of patients for CRT.

Abstract
Abstract
Background
Diagnosing heart failure with preserved ejection fraction (HFpEF) still remains challenging, and simple and reliable diagnostic tools have been required. Recently, novel and evidence-based diagnostic algorithms for HFpEF were proposed, such as H2FPEF score (Circulation. 2018) and HFA-PEFF score (Eur Heart J 2019), and their accuracy was validated in the outside patient group. However, there are regional and ethnic variations in patient characteristics of HFpEF, particularly between Western and Asian countries, and it is not elucidated whether these diagnostic scores are useful in Asian population.
Purpose
To investigate the validity of the HFA-PEFF- and H2FPEF score in Japanese patients with HFpEF.
Methods
We calculated H2FPEF score and the second step of HFA-PEFF score among the registered patients in the PURSUIT-HFpEF (Prospective, Multicenter, Observational Study of Patients with Heart Failure with Preserved Ejection Fraction) study, which is a multicenter registration of patients hospitalized for HFpEF. The obtained scores were compared with the scores of the HFpEF cohort in the previous validation studies. We followed the study patients for median of 360 days (IQR 237–630 days) to observe the major adverse cardiovascular events (MACE; composite of death, heart failure hospitalization and stroke).
Results
We enrolled 757 patients hospitalized for HFpEF between June 2016 and August 2019 for the present study. H2FPEF score was obtained in 588 (77.7%) patients among them. Compared with the HFpEF cohorts in the previously reported sub-analysis of TOPCAT trial, the PURSUIT-HFpEF cohort had lower mean value of HFpEF score (4.0±1.8 points vs. 6.0±2.0 points in Americans or 5.3±1.9 points in Russians). It had significantly higher proportion (40.3%, p<0.001) of patients in the low likelihood of HFpEF category (0–3 points) than the TOPCAT cohorts (8.0% in Americans and 19.6% in Russians).
HFA-PEFF score was obtained in 615 (81.2%) patients, though global longitudinal strain was not available. The mean value of HFA-PEFF score was 5.0±0.8, and all patients had ≥2 points. The proportion of patients in the high likelihood of HFpEF category (5–6 points) was 88.3%, which was significantly higher (p<0.001) than those of the HFpEF cohort from Europe and USA in the previous validation study (Eur J Heart Fail 2019). There was no correlation between H2FPEF score and HFA-PEFF score (R=0.06, p=0.14). Cox proportional hazard model selected HFA-PEFF score as a significant predictor for MACE during follow-up period, whereas H2PEF score was not selected. Kaplan-Meier survival analysis demonstrated that patients with 6 points of HFA-PEFF score had higher incidence rate of MACE than those with ≤5 points (p=0.002).
Conclusion
The HFA-PEFF score could be more useful for the diagnosis and risk stratification for HFpEF than the H2PEF score in the Japanese cohort.

Abstract
Abstract
Background
Triglyceride deposit cardiomyovasculopathy (TGCV) is a novel cardiovascular disorder, encoded as orphan disease in Europe in 2019, characterized by excessive accumulation of triglyceride in vascular smooth muscle cells, leading to coronary artery disease (CAD). However, there is no data about impact of TGCV on vascular failure after coronary stent implantation.
Purpose
To assess impact of TGCV on the outcome following coronary stent implantation in CAD patients with diabetes mellitus (DM) as Study 1, and chronic hemodialysis as Study 2.
Methods
This is multicenter retrospective estimation consisting of two studies.
Study 1) Among 526 consecutive patients suspected of having CAD who underwent coronary angiography (CAG) and iodine-123-β-methyliodophenyl-pentadecanoic acid (BMIPP) scintigraphy, a tracer for the diagnosis of TGCV, data from 81 patients with DM were analyzed.
The patients were divided into two groups; TGCV (n=7) or non-TGCV (n=74). All patients were implanted with a second-generation DES and underwent follow-up CAG. Binary restenosis (ISR), defined as angiographic luminal diameter >50% by quantitative coronary angiography, in-stent late loss were assessed in 15 stents of TGCV patients and 111 stents of non-TGCV patients.
Study 2) Similarly, among 88 chronic hemodialysis patients, ISR and in-stent late loss were assessed in 12 stents of 9 TGCV patients and 21 stents of 17 non-TGCV patients.
Results
Study 1) There were no significant differences in baseline characteristics between the two groups. In-stent late loss was greater in TGCV group than in non-TGCV group (0.91mm [0.27, 2.39] vs. 0.15mm [0.03, 0.35]; p<0.001), resulting in greater incidence of ISR in TGCV group than in non-TGCV group (46.7% vs. 9.0%; p<0.001). Multivariable logistic analysis revealed TGCV to be an independent predictor for vascular failure after DES implantation in patients with DM.
Study 2) Similarly, in-stent late loss and incidence of ISR were greater in TGCV group than in non-TGCV group (1.20±0.99mm vs. 0.50±0.70, p=0.02; 58.3% vs. 9.5%, p=0.002, respectively). TGCV was an independent predictor for vascular failure after DES implantation in chronic hemodialysis patients.
Conclusion
Apart from existing risk factors such as DM and hemodialysis, TGCV could contribute to a novel risk factor for vascular failure, even in the second-generation DES era.

Abstract
Abstract
Background
The degree of mechanical dyssynchrony has been suggested as a predictor for long-term survival after cardiac resynchronization therapy (CRT). There have been little reports of dyssynchrony assessment with the use of cardiac computed tomography (CCT).
Methods
We studied 35 heart failure (HF) patients (average age 67±10 years) referred for CRT with NYHA III-IV heart failure, left ventricular (LV) ejection fraction (EF) 20±10% (all ≤35%), and QRS duration 156±22 ms (all ≥120ms). Electrocardiogram-gated contrast-enhanced 256-slice multidetector CT was performed before CRT. Based on CCT, the LV endocardial boundaries from short-axis images reconstructed at 5% increments of cardiac cycle were automatically detected, and the time from R-wave to maximal wall motion was calculated for each of the 16 standardized segments for all slices using software “Myocardial Contraction Map”. The standard deviation modified by mean heart rate (%SD) was respectively calculated as the global parameter of dyssynchrony. LVEF was also measured using MDCT. The predefined primary end-point was the first HF hospitalization or death over 2 years.
Results
%SD was feasible in all patients, respectably. There were 16 events over 2 years; 11 HF hospitalizations and 5 deaths. Patients with %SD ≥22% (optimal cutoff for outcome by ROC curve analysis) had a better clinical outcome than patients with %SD <22% (p=0.01, Figure).
Conclusion
Patients who had %SD ≥22% assessed by MDCT had a particularly favorable event-free survival following CRT, and this appears to be an important prognostic marker.

Abstract
Abstract
Background
Catheter ablation of atrial fibrillation (AF) is effective, but certain patients experience AF recurrences. Obstructive sleep apnea (OSA) is a risk factor for AF recurrence. Watch peripheral arterial tonometry (WP) has a good correlation with polysomnography (PSG) in terms of the apnea-hypopnea index (AHI) and is easier to perform than PSG. Patients in AF have a high prevalence of OSA. Whether all patients with AF should be evaluated for OSA before catheter ablation is still controversial.
Purpose
To elucidate the prevalence and predictors of OSA using WP as a home sleep apnea test in AF patients before catheter ablation.
Methods
This study was conducted under a retrospective, single-center, observational design. Patients who received AF ablation without a prior diagnosis of sleep apnea and assessment of their AHI using WP were included in this analysis. The patients were mounted with a WP device by themselves at their own home. Twenty-two patients who were already diagnosed with OSA were excluded.
Results
Seven hundred seventy-four (65±11 years, 567 males, 440 paroxysmal AF) out of 776 patients were successfully mounted with WP devices on their own and underwent an OSA assessment. Their mean body mass index (BMI) was 24.1±3.5 kg/m2. The mean AHI was 20.1±15.6. Only 88 (11.4%) patients had a normal AHI (AHI<5). Mild OSA (5≤AHI<15), moderate OSA (15≤AHI<30), and severe OSA (AHI≥30) were observed in 274 (35.4%), 252 (32.6%), and 160 (20.7%) patients, respectively. A BMI≥25 (odds ratio [OR]; 2.42, 95% confidence interval [CI]; 1.74–3.37, p<0.001), male sex (1.70, 1.19–2.44, p=0.0037), non-paroxysmal AF (1.90, 1.35–2.66, p=0.0002), hypertension (1.70, 1.24–2.33, p=0.009), and left atrial volume index ≥30 (OR=1.51, CI 1.06–2.16, p=0.022) were significant predictors of moderate or severe OSA by a multivariate analysis, while an Epworth sleepiness scale ≥11 was not a predictor of moderate or severe OSA (OR=0.99, CI 0.66–1.49, p=0.95). However, 44.2% of non-obese patients (BMI <25) had moderate-severe OSA.
Conclusion Almost
All patients successfully underwent WP to diagnose OSA. AF patients had a high prevalence of OSA, and screening OSA would be important in AF patients receiving ablation even if patients do not have sleepiness or are obese. We cannot deny OSA in AF patients before catheter ablation without performing screening tests for OSA.

Abstract
Abstract
Introduction
Frailty and aging are two common conditions both associated with increased vulnerability to stressful events with high risk of adverse outcomes.
Purpose
To evaluate the association between frailty and aging and their impacts on clinical outcome in patients with heart failure with preserved ejection fraction (HFpEF).
Methods
Analysis was performed from a prospective multicenter observational registry for HFpEF (PURSUIT-HFpEF Registry) conducted in the Osaka region of Japan. A total of 757 patients hospitalized for acute heart failure (diagnosed by using Framingham criteria) met the inclusion criteria: a left ventricular ejection fraction ≥50% and brain natriuretic peptide ≥100pg/ml. We included 483 patients (age, 80±9 years; men, 45%; atrial fibrillation, 35%) whose follow-up data after survival discharge were available. Patients' frailty and aging were evaluated using the clinical frailty scale (CFS) and age quartiles (Q1: <76 years (n=122), Q2: 76–82 years (n=111), Q3: 82–87 years (n=127), Q4: >87 years (n=123)), respectively. The primary clinical endpoint was defined as the composite of death, re-hospitalization for heart failure, and cerebrovascular accident.
Results
The median (interquartile range) CFS rating was 3 (2–5), and there was a little correlation between CFS rating and age (r2=0.16, p<0.001). The prevalence of frailty, defined as a CFS rating >4 (n=132), was positively correlated with age quartiles (Q1: 9.0%, Q2: 21.4%, Q3: 29.9%, Q4: 48.0%, p<0.001). During the median follow-up period 396 days (interquartile range, 344–698) after discharge, the clinical endpoint was observed in 172 patients. The incidence was higher in patients with frailty than those without it (49.6% vs. 30.4%, log-rank p<0.001). It was also correlated with age quartiles (Q1: 23.0%, Q2: 34.2%, Q3: 36.2%, Q4: 48.8%, log-rank p=0.001). Multivariate Cox regression analysis revealed that frailty (hazard ratio, 1.52; 95% confidence interval, 1.09–2.10; p=0.013) and age (hazard ratio per quartile increase, 1.24; 95% confidence interval, 1.07–1.43; p=0.004) were both associated with the clinical endpoint. Subgroup analysis in 352 patients without frailty also revealed the significant impact of age on the endpoint (1.26; 1.06–1.51; p=0.008). However, in 131 patients with frailty, there was no significant impact of age on the endpoint (1.16; 0.90–1.51; p=0.25).
Conclusions
Frailty was common and was associated with aging in HFpEF patients. Although they were both associated with unfavorable events, aging was no longer a significant predictor of adverse outcomes under the frailty conditions.

Abstract
Abstract
Introduction
Structural remodeling is an important aspect of pathophysiology of heart failure (HF). The compensatory mechanism against diastolic dysfunction would be more obvious on the left atrium rather than left ventricle in HF with preserved ejection fraction (HFpEF).
Purpose
To investigate the impact of left atrial (LA) and left ventricular (LV) remodeling on clinical outcomes in HFpEF patients.
Methods
Analysis was performed from a prospective multicenter observational registry for HFpEF (PURSUIT-HFpEF Registry) conducted in the Osaka region of Japan. A total of 757 patients hospitalized for acute HF (diagnosed by using Framingham criteria) met the inclusion criteria: a LV ejection fraction ≥50% and brain natriuretic peptide ≥100pg/ml. We included 381 patients (age, 82±9 years; men, 45%; atrial fibrillation (AF), 34%) whose follow-up data after survival discharge were available and whose LA volume index (LAVI) and left ventricular end-diastolic volume index (LVEDVI) at discharge were measured by the biplane Simpson's method using echocardiography. The primary endpoint was defined as the composite of death, re-hospitalization for HF, and cerebrovascular accident.
Results
The LAVI and LVEDVI at discharge was 54±25 ml/m2 and 55±21 ml/m2, respectively (r2=0.014, p=0.021). When patients were classified into the LAVI tertiles groups (T1: <40ml/m2 (n=124), T2: 41–59ml/m2 (n=127), T3: >60ml/m2 (n=130)), there was a positive correlation between the prevalence of diastolic dysfunction and the LAVI tertiles (T1, 21.0%; T2, 48.8%; T3, 51.5%; p<0.001). On the other hand, significant association was not observed between the prevalence of diastolic dysfunction and the LVEDVI tertile groups (p=0.42). During the median follow-up period of 396 days (IQR, 345–698), the composite endpoint was observed in 131 patients and there was a positive correlation between the endpoint and the LAVI tertiles (T1, 24.2%; T2, 38.6%; T3, 40.3%; p=0.011). On the other hand, no correlation was found between the endpoint and the LVEDVI tertiles (p=0.13). After adjustment for age, gender, and presence of diastolic dysfunction, Cox regression analysis revealed that not LVEDVI but LAVI at discharge was a significant predictor of the composite endpoint in the entire cohort (hazard ratio per 10 ml/m2 increase; 1.09; 95% confidence interval, 1.02–1.16; p=0.009) and in the sinus rhythm subgroup (1.10; 1.01–1.20; p=0.034). However, not LAVI but LVEDVI was a significant predictor for the adverse outcomes in the AF subgroup (1.23; 1.04–1.46; p=0.016).
Conclusions
Increased LAVI at discharge, which was associated with diastolic dysfunction, related to unfavorable prognosis in patients with HFpEF. However, LAVI was no more a predictor for the adverse outcomes but LVEDVI was in the AF subgroup. The clinical significance of atrial and ventricular remodeling may differ between sinus rhythm and AF rhythm in HFpEF population.

Abstract
Abstract
Background
Although dobutamine stress echocardiography (DSE) at the early stage of acute myocardial infarction (AMI) is useful for the prediction of functional and clinical prognosis, the interpretation requires expertise. In this study, we sought to investigate if global longitudinal strain (GLS) during DSE after AMI can predict left ventricular remodeling (LVR).
Methods
Consecutive 30 patients with anterior wall AMI (18 male, age = 58 ± 13 years) were performed DSE 3 days after AMI. GLS was calculated as an averaged value of peak longitudinal strain in the apical 4- and 2-chamber views at baseline echocardiography, low-dose DSE (10 μg/kg/min) using available software (QLAB, Philips Medical Systems). Left ventricular remodeling (LVR) was defined as an echocardiographically determined increase in both EDVI and ESVI of 20% or more from baseline to the 6 month follow-up echocardiography.
Results
12 patients (40%) evolved with LVR. The change in GLS during low-dose DSE was significantly different between the remodeling and non-remodeling group (8 ± 5% v.s. 27 ± 20%, p < 0.05). Interestingly, it predicted LVR with sensitivity of 88%, specificity of 92% at the cut-off value of 12% (Area under the curve = 0.94, p < 0.0001).
Conclusion
The change in GLS during low-dose DSE can be used as a predictor for the LVR after AMI. This observation has promise for clinical applications.

Abstract
Abstract
Background
Triglyceride deposit cardiomyovasculopathy (TGCV) is a novel clinical concept found among Japanese cardiac transplant recipients in 2008 that the abnormal intracellular triglyceride (TG) metabolism results in the ectopic accumulation of TG in vascular smooth muscle cells and cardiomyocytes, leading to diffuse narrowing coronary artery disease (CAD) and heart failure. TGCV is estimated to affect almost forty to fifty-thousand people in Japan, but there is no real-world date about the prevalence or latency.
Purpose
To evaluate TGCV latency in population with CAD, especially requiring urgent coronary angiography as Study 1, and chronic hemodialysis as Study 2.
Methods
This is multicenter retrospective estimation consisting of two studies.
Study 1) From 2012 to 2017, consecutive 400 patients of unstable angina or acute myocardial infarction who underwent urgent coronary angiography (CAG) and following iodine-123-β-methyliodophenyl-pentadecanoic acid (BMIPP) scintigraphy, a tracer for the diagnosis of TGCV, were enrolled.
Study 2) From 2011 to 2017, 88 chronic hemodialysis patients who underwent planed CAG and BMIPP scintigraphy for detection of ischemic heart disease were enrolled.
TGCV was diagnosed based on the latest diagnostic criteria for TGCV. The criteria include two major items (2 points each: BMIPP scintigraphy Wash-Out Rare <10%, Diffuse narrowing coronary arteries) and two minor items (1 point each: Jordans' anomaly in peripheral blood smear, Diabetes). Four points or more and three points indicated definite and probable TGCV, respectively. Only Items other than Jordans' anomaly were available for the diagnosis of TGCV because of retrospective nature. We evaluated the latent rate of definite and probable TGCV.
Results
Study 1) Figure (left) demonstrates the result of Study 1. Definitive TGCV patients were 14 patients, accounting for 3.5% of total 400 patients, and probable TGCV patients were 39 patients, accounting for 9.8% of all. Total 53 definitive and probable TGCV patients accounted for 13.3% of all. Annual average latency were 3.6±1.7% as definitive, 10.0±5.5% as probable and 13.6±6.6% as definitive and probable TGCV, respectively.
Study 2) Figure (right) demonstrates the result of Study 2. Definitive TGCV patients were 17 patients, accounting for 19.3% of total 88 hemodialysis patients, and probable TGCV patients were 22 patients, accounting for 25.0% of all. Total 39 definitive and probable TGCV patients accounted for 44.3% of all. Annual average latency of definitive TGCV was 19.3±13.4%. Of the 17 definitive TGCV patients, 9 patients were hemodialysis patients with diabetes.
Figure 1
Conclusions
TGCV might be latent with a probability of 3.6±1.7% per year in patients with unstable angina or acute myocardial infarction, and with a probability of 19.3±13.4% per year in chronic hemodialysis patients suspected of ischemic heart disease.

Abstract
The application of extracellular matrix (ECM) sheets without a scaffold is not extensively reported in bone regenerative medicine. The aim of the present study was to demonstrate that an osteogenic ECM sheet (OECMS) can retain ECM integrity and growth factors to enhance bone formation in a rat non-union model. OECMS was produced from osteogenic cell sheets (OCS). Collagen and growth factor [bone morphogenetic protein 2 (BMP-2), vascular endothelial growth factors (VFGFs), basic fibroblast growth factor (bFGF) and transforming growth factor β1 (TGF-β1)] concentrations in the OECMS were quantified by enzyme-linked immunosorbent assay (ELISA). Next, hydroxyapatite (HA) constructs combined with OECMSs were implanted subcutaneously into the rats' backs to evaluate their osteoinductive capacity by histological evaluation. In addition, OECMSs were implanted in a rat femoral non-union model. 18 male Fischer 344 inbred rats were divided into OECMS and control groups. Fracture healing was evaluated by radiological and histological analyses at 2, 5 and 8 weeks and biological analysis at 8 weeks. Collagen I and growth factors were retained in the OECMSs. Osteoid formation was identified in the HA combined with OECMS at 4 weeks. Enhanced bone regeneration at the non-union of the OECMS group was confirmed at 5 and 8 weeks. Biomechanical testing revealed a significantly higher maximum bending load in the OECMS group as compared to the control group at 8 weeks. The results demonstrated that OECMS retained BMP-2 and TGF-β1 and high osteoinductive and osteoconductive capacity. As such, OECMS represents a potential new scaffold-free material for bone tissue engineering.

Abstract
The Hyp mouse is a murine homologue of human X-linked hypophosphatemia that displays hypo-mineralization in bone and dentin. In this study, we tested the hypothesis that the defect in Hyp mice leads to alterations in the expression of dentin matrix proteins that may be associated with the hypo-mineralization changes in the tissues. Quantitative RT-PCR analyses showed that expression of the osteocalcin gene in Hyp mice tooth germ samples was significantly higher than in wild-type mice, whereas the gene expressions of osteonectin, osteopontn, dentin matrix protein 1, and type I collagen in both types of mice were similar. Further, cultured Hyp mice tooth germ samples exhibited a higher expression of the osteocalcin gene than did those from wild-type mice, which was in accord with the results of our in vivo analysis. These findings suggest that osteocalcin mRNA is highly expressed in Hyp mice odontoblasts and may be associated with dentin hypo-mineralization.

Abstract
Objectives To assess the structure and extracellular matrix molecule expression of osteogenic cell sheets created via culture in medium with both dexamethasone (Dex) and ascorbic acid phosphate (AscP) compared either Dex or AscP alone. Methods Osteogenic cell sheets were prepared by culturing rat bone marrow stromal cells in a minimal essential medium (MEM), MEM with AscP, MEM with Dex, and MEM with Dex and AscP (Dex/AscP). The cell number and messenger (m)RNA expression were assessed in vitro, and the appearance of the cell sheets was observed after mechanical retrieval using a scraper. β-tricalcium phosphate (β-TCP) was then wrapped with the cell sheets from the four different groups and subcutaneously implanted into rats. Results After mechanical retrieval, the osteogenic cell sheets from the MEM, MEM with AscP, and MEM with Dex groups appeared to be fragmented or incomplete structures. The cell sheets cultured with Dex/AscP remained intact after mechanical retrieval, without any identifiable tears. Culture with Dex/AscP increased the mRNA and protein expression of extracellular matrix proteins and cell number compared with those of the other three groups. More bridging bone formation was observed after transplantation of the β-TCP scaffold wrapped with cell sheets cultured with Dex/AscP, than in the other groups. Conclusions These results suggest that culture with Dex/AscP improves the mechanical integrity of the osteogenic cell sheets, allowing retrieval of the confluent cells in a single cell sheet structure. This method may be beneficial when applied in cases of difficult tissue reconstruction, such as nonunion, bone defects, and osteonecrosis. Cite this article: M. Akahane, T. Shimizu, T. Kira, T.

Abstract
Background. Metachronous solitary metastasis of renal cell carcinoma (RCC) to the contralateral adrenal gland is very rare. We assessed the clinocopathological findings of such patients who received adrenalectomy. Methods. We retrospectively reviewed the records of all 495 patients who underwent nephrectomy for RCC; excluding those in stage IV, between 1980 and 1993. Of these patients, 5 who showed metachronous solitary metastasis to the contralateral adrenal gland, and also received adrenalectomy were the subjects of this study. Results. The adrenal metastasis was found between 14 and 132 months (median, 81 months) after nephrectomy. After the solitary adrenalectomy, patient survival ranged from 450 to 2160 days (median, 660 days); 2 patients were alive with no evidence of disease at 660 and 1830 days, respectively, and 3 patients died of this disease, at 450, 480, and 2160 days, respectively, after adrenalectomy. The overall survival rate was 100% at 5 years, 80% at 6 years, 60% at 7 years, and 40% thereafter. The 2 patients with no evidence of disease did not receive steroid supplementation, because they had not received ipsilateral adrenalectomy. No significant difference was observed between survivors and non-survivors in terms of clinicopathological factors such as affected side, location of the tumor, tumor size of primary/metastatic lesion, and stage or grade of primary/metastatic lesion. From the viewpoint of outcome, patients with early recurrence tended to show an unfavorable prognosis compared with prognosis in those with late recurrence. Conclusion. The prediction of outcome in patients with RCC who undergo, adrenalectomy for metachronous solitary metastasis to the contralateral adrenal gland is difficult. Although the factors that affect prognosis are uncertain, long-term observation for unusual metachronous metastasis to the contralateral adrenal gland is mandatory in patients with RCC.
