Abstract
A newly found leaf arrangement to reduce self-shading was observed in a Japanese warm-temperate forest. For monoaxial trees that deploy leaves directly on a single stem, leaf arrangements involving progressive elongation of the petiole and progressive increase in deflection angle (the angle between stem and petiole) from the uppermost to the lowermost leaves act to reduce self-shading. However, the progressive reduction in petiole length and deflection angle from the uppermost to the lowermost leaves should also result in the reduction of self-shading. Nevertheless, the latter leaf arrangement has not been reported previously for any tree species. Four Araliaceae species, namely, Gamblea innovans, Chengiopanax sciadophylloides, Dendropanax trifidus and Fatsia japonica, which are typical monoaxial tree species in Japan, were studied. We examined the crown structure of saplings growing in the light-limited understorey in a Japanese warm-temperate forest. Two evergreen species, Dendropanax trifidus and F. japonica showed progressive petiole elongation and progressive increase in the deflection angle from the uppermost to the lowermost leaves. In contrast, saplings of deciduous species, G. innovans and C. sciadophylloides had a leaf arrangement involving progressive reduction in petiole length and deflection angle from the uppermost to the lowermost leaves. The leaf arrangement has diversified among members of the same family, but all four studied species develop a crown with little self-shading that is adapted for growth in the light-limited understorey. Although trees are likely to be under the same selective pressure to reduce self-shading, this study revealed that there is flexibility in its morphological realisation, which has been poorly appreciated previously.

Abstract
The paper provides a precise error estimate for an asymptotic expansion of a certain stochastic control problem related to relative entropy minimization. In particular, it is shown that the expansion error depends on the regularity of functionals on path space. An efficient numerical scheme based on a weak approximation with Monte Carlo simulation is employed to implement the asymptotic expansion in multidimensional settings. Throughout numerical experiments, it is confirmed that the approximation error of the proposed scheme is consistent with the theoretical rate of convergence.

Abstract
PURPOSE To develop an imaging prediction model for patients with embolic stroke of undetermined source (ESUS), we investigated the association of topographic diffusion-weighted imaging (DWI) patterns with potential embolic sources (PES) identified by transesophageal echocardiography. METHODS From a total of 992 consecutive patients with embolic stroke, 366 patients with the ESUS group were selected. ESUS was defined as no atrial fibrillation (Af) within 24h from admission and no PES after general examination. Clinical variables include age (> 80years, 70-80 years), sex, vascular risk factors and left atrial diameter > 4 cm. Age, sex and vascular risk factors adjusted odds ratio of each DWI for the different PESs were calculated. DWI was determined based on the arterial territories. Middle cerebral arteries were divided into 4 segments, i.e., M1-M4. Moreover, M2 segments were subdivided into superior and inferior branches. RESULTS The 366 patients consisted of 168 with paroxysmal Af (pAf), 77 with paradoxical embolism, 71 with aortic embolism and 50 with undetermined embolism after transesophageal echocardiography. The variables adjusted odds ratio (OR) of internal carotid artery (OR: 12.1, p = 0.037), M1 (4.2, p = 0.001), inferior M2 (7.5, p = 0.0041) and multiple cortical branches (12.6, p < 0.0001) were significantly higher in patients with pAf. Striatocapsular infarction (12.5, p < 0.0001) and posterior inferior cerebellar artery infarcts (3.6, p = 0.018) were significantly associated with paradoxical embolism. Clinical variables adjusted OR of multiple small scattered infarcts (8.3, p < 0.0001) were significantly higher in patients with aortic embolism. CONCLUSION The associations of DWI with different PES have their distinctive characteristics and DWI along with clinical variables may help predict PES in patients with ESUS.

Abstract
In the Malvaceae family, dynamic solar tracking by leaves is actuated by the deformation of the pulvinus, a thickened region at the leaf blade-petiole junction. While the internal structure is believed to play a crucial role in this process, experimental verification has been challenging due to technical limitations. To address this gap, we developed a semi-automated workflow, which integrates data analysis and image processing to simultaneously analyze the shape and internal structure of a Malvaceae pulvinus using X-ray microtomography. Firstly, we found that kenaf (Hibiscus cannabinus L.), a Malvaceae species with curved pulvini, exhibited solar-tracking leaf movement and selected it as a model system. We employed diffusible iodine-based contrast-enhanced computed tomography to visualize the internal structure of the kenaf pulvinus. Analysis of the pulvini's shape revealed variations in pulvinus morphology, yet plausible prediction of the centerline was accomplished using polar polynomial regression. Upon slicing the pulvini perpendicular to the centerline, we observed distinct gray value gradients along the proximo-distal and adaxial-abaxial axes, challenging threshold-based tissue segmentation. This workflow successfully generated three modified 3D images and derived quantitative parameters. Using these quantitative parameters, we conducted network analysis and found the linkage between the size-normalized cortex cross-sectional area and curvature. Polynomial least absolute shrinkage and selection operator (LASSO) regression revealed the relationship between the size-normalized cortex cross-sectional area and curvature commonly in all three tested samples. This workflow enables simultaneous analysis of the shape and internal structure, significantly improving the reproducibility of Malvaceae leaf pulvinus characterization.

Abstract
PURPOSE/OBJECTIVE(S) The effectiveness of stereotactic body radiation therapy (SBRT) for hepatocellular carcinoma (HCC) has been shown in many studies and its therapeutic effect is similar to radiofrequency ablation (RFA). However, many of these studies were done in combination with transcatheter chemoembolization (TACE), for recurrent HCC, or on a small scale. To better understand the specific outcomes of SBRT for HCC, we conducted a multicenter retrospective analysis of SBRT for previously untreated initial HCC at Japanese Society of Clinical Oncology (JCOG) member hospitals. MATERIALS/METHODS Patientswho underwent SBRT for HCC at JCOG member hospitals between July 2013 and December 2017 and met the following eligibility criteria were included: (1) initial HCC; (2) ≤ 3 nodules, ≤ 5 cm in diameter; (3) a Child-Pugh (CP) score of A or B; and (4) unsuitability for or refusal of standard treatment, such as surgery, transplantation, RFA and TACE. We evaluated the overall survival (OS), recurrence-free survival (RFS) which was defined as the first instance of intra-hepatic recurrence after SBRT, disease-specific survival (DSS) using Kaplan-Meier analysis. Using Grey's test, patients who died of other diseases were analyzed as competing risks to estimate the cumulative incidence of local recurrence (CLR). Adverse events directly related to SBRT also analyzed using Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). RESULTS Seventy-three patients with 79 lesions from 14 hospitals were analyzed. The median age was 77 years (range; 50-89 years), and the median tumor size was 23 mm (range; 6-50 mm). The median radiation dose was 40 Gy (range; 35-60 Gy) in five fractions (range; 4-8). The median follow-up period was 45 months (range; 0-103 months). There were three cases where follow-up was not possible due to unexpected events unrelated to SBRT, while the remaining 70 patients were successfully followed for at least six months. The 2 and 3year OS, RFS, DSS, and CLR rates were 84.3% (95% CI: 75.8-92.8%) and 69.9% (95% CI: 58.7-81%), 67.5% (95% CI: 56.0-79.0%) and 57.9% (95% CI: 45.2-70.5%), 95.1% (95% CI:89.7-100%)/87.6% (95% CI:78.8-96.3%), and 11.4% (95% CI: 5.3-20.0%) and 20.0% (95% CI: 11.2-30.5%), respectively. Four cases (5.5%) of adverse events of grade 3 or higher were reported: one case of grade 3 laboratory toxicities, one case of grade 3 liver failure, one case of grade 3 portal tumor thrombosis, and one case of grade 4 duodenal ulcer. No grade 5 toxicities were observed. CONCLUSION The results of our study demonstrate that SBRT for HCC is highly effective in achieving local control and is safe to administer. In addition, survival outcomes are favorable. SBRT is a promising treatment modality, especially for small HCCs for that is not suitable for standard treatment.

Abstract
Byttneriophyllum tiliifolium is a leaf fossil-species of the family Malvaceae that was distributed widely throughout Eurasia from the Miocene to the Pliocene. An affinity to some Malvadendrina subfamilies has been suggested for Byttneriophyllum-bearing plants, but remains to be clarified due to insufficient information on other organs. Here, we report an exceptional lower Miocene fossil locality in Japan where a monodominant forest of the wood fossil-species Wataria parvipora flourished. Notably, the forest floor was covered by a bed consisting almost exclusively of B. tiliifolium. We observed occurrence modes of B. tiliifolium in this bed that confirmed that these leaves were deposited parautochthonously. These observations imply a biological connection between B. tiliifolium and W. parvipora. The wood and leaf characters together might narrow the affinity of Byttneriophyllum-bearing plants down to Helicterioideae within the Malvadendrina, although it is also possible that Byttneriophyllum-bearing plants constitutes an extinct lineage which is characterized by a combination of morphological traits found in several extant lineages. Our results suggest that Byttneriophyllum-bearing plants started to inhabit swamps no later than the end of the early Miocene when the global temperature was getting warmer.

Abstract
Phyllostachys nigra var. henonis, a monocarpic bamboo with a 120-year flowering interval, is next predicted to flower in Japan in the 2020s. Because a huge area of the country is presently covered by stands of this species, post-flowering dieback of these stands and ensuing drastic changes in land cover may cause serious social and/or environmental problems. No study on the regeneration of this bamboo species was conducted during the last flowering event in the 1900s, and the regeneration process of this species is thus still unknown. In 2020, we encountered a localized flowering of P. nigra var. henonis in Japan and used this discovery as a rare opportunity to study the initial regeneration process of the species. Over 3 years, more than 80% of culms in the study site bloomed, but no seed was produced. In addition, no established seedlings were located. These facts strongly suggest that P. nigra var. henonis lacks the ability to produce seeds and cannot undergo sexual regeneration. Some bamboo culms were produced after flowering but died within 1 year of emergence. Small, weak culms (dwarf ramets) also appeared after flowering, but most died within 1 year as well. Three years after flowering, all culms had died, with no sign of regeneration detected. According to our 3 years of observation, this bamboo appears to be hard to regenerate-an idea completely contradicted by the fact that this species has long persisted in Japan. We thus considered other possible regeneration modes for P. nigra var. henonis.

Abstract
Samples of the carbonaceous asteroid Ryugu were brought to Earth by the Hayabusa2 spacecraft. We analyzed 17 Ryugu samples measuring 1 to 8 millimeters. Carbon dioxide-bearing water inclusions are present within a pyrrhotite crystal, indicating that Ryugu's parent asteroid formed in the outer Solar System. The samples contain low abundances of materials that formed at high temperatures, such as chondrules and calcium- and aluminum-rich inclusions. The samples are rich in phyllosilicates and carbonates, which formed through aqueous alteration reactions at low temperature, high pH, and water/rock ratios of <1 (by mass). Less altered fragments contain olivine, pyroxene, amorphous silicates, calcite, and phosphide. Numerical simulations, based on the mineralogical and physical properties of the samples, indicate that Ryugu's parent body formed ~2 million years after the beginning of Solar System formation.

Abstract
Late Silurian to early Devonian lycophytes had prostrate aerial axes, while subordinate organs or subterranean axes were formed around the dichotomies of the axes. The subterranean axes are hypothesized to have evolved into root-bearing axes (rhizophores) and roots in extant Selaginellaceae and Lycopodiaceae, respectively. Consistent with this hypothesis, rhizophores are formed on the dichotomies of shoots in Selaginellaceae. However, it has remained unclear whether roots are borne in the same position in Lycopodiaceae. In addition, roots form endogenously in the stem, but no data are available regarding the tissues in stem from which they arise. In this study, we tracked the root development in the clubmoss, Lycopodium clavatum, based on anatomical sections and 3D reconstructed images. The vascular tissue of the stem is encircled by ground meristem, which supplies cortical cells outwardly by periclinal divisions. A linear parenchymatous tissue is present on the ventral side of vascular cylinder, which we call “ventral tissue” in this study. We found that root primordia are formed endogenously on the ventral side of stem, possibly from the ventral tissue. In addition, roots always initiate at positions close to dichotomies of stem. The root-initiating position supports the suggestion that Lycopodium roots share a body plan with the subterranean organs of the hypothesized ancestry.

Abstract
Abstract
Background
Systemic inflammation resulting from comorbidities is postulated to play a central role in the pathophysiology of heart failure (HF) with preserved ejection fraction (HFpEF). Lymphopenia is a common manifestation of systemic inflammation and a prognostic factor in patients with HF. However, the association of lymphopenia with the comorbidity burden is unknown, and its prognostic value in patients with HFpEF admitted due to acute decompensated heart failure (ADHF) also remains elusive.
Purpose
We sought to clarify the relation of lymphopenia with the comorbidity burden, as well as its prognostic value and complementarity with the Get with the Guidelines-Heart Failure (GWTG-HF) risk score in ADHF patients with HFpEF.
Methods
Patients' data were extracted from the Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT-HFpEF), which is a prospective multicentre registry for patients with ADHF with a LVEF ≥50%. We analysed data of patients admitted between June 2016 and December 2020 who survived to discharge. The total lymphocyte count (per μL) and GWTG-HF risk score were obtained on admission, as previously reported. Comorbidity burden was defined as the number of comorbidities from the following: atrial fibrillation, hypertension, diabetes mellitus, coronary artery disease, chronic kidney disease, chronic obstructive pulmonary disease, anaemia, and obesity. The study endpoint was all-cause death.
Results
Over a median follow-up of 417 days, 181 of the 1013 included patients died. The proportion of patients with a total lymphocyte count in the lowest tertile was increasing with the increase in comorbidity burden (Figure 1). In the multivariate Cox analysis, a total lymphocyte count in the intermediate (hazard ratio [HR] 1.55, 95% confidence interval [CI] 1.00–2.41, p=0.0486) and lowest tertile (HR 2.23, 95% CI 1.47–3.38, p=0.0002) was independently associated with all-cause death. There was a significant difference in the all-cause death rate among the groups stratified by total lymphocyte count tertile (Figure 2). The total lymphocyte count had a higher C-statistic value (0.627) for the prediction of all-cause death than the GWTG-HF risk score, and the C-statistic value of the GWTG-HF risk score was improved when the total lymphocyte count was added (0.613 to 0.636, p=0.0260).
Conclusions
Lymphopenia was significantly associated with comorbidity burden. Furthermore, it was a useful marker of poor prognosis in hospitalised patients with acute HFpEF and was shown to be complementary to the contemporary HF prognostic score.

Abstract
Abstract
Background
Heart failure (HF) with preserved ejection fraction (HFpEF) is a chronic and progressive disease, but limited therapeutic strategies are currently available. Although left ventricular diastolic dysfunction (DD) is a prominent mechanism of HFpEF, a certain number of patients with HFpEF have a normal diastolic function (ND) or indeterminate diastolic function (ID). With the progressive nature of HFpEF, diastolic function may change over time. However, the change of diastolic function, its predictor and prognosis in patients with clinically established HFpEF remains unknown.
Purpose
To investigate the clinical trajectory and outcomes of patients with HFpEF with ND or ID and to identify factors associated with progression from ND or ID at discharge to DD at 1-year follow-up.
Methods
Using data from a prospective multicenter observational study of patients with HFpEF, we extracted 289 patients with HFpEF with ND or ID at discharge who had echocardiographic data at 1-year follow-up for the re-evaluation of diastolic function. Diastolic function was assessed according to the 2016 American Society of Echocardiography recommendations. Patients were classified according to the absence or presence of progression from ND or ID to DD at 1 year. The primary endpoint was a composite of all-cause death and HF rehospitalization.
Results
Median age was 81 years, and 138 (47.8%) patients were female. At 1 year, 107 (37%) patients progressed to DD. During a median follow-up of 709 days, the composite endpoint occurred in 90 (31.1%) patients. Compared to patients without progression to DD, those with progression to DD had a significantly higher cumulative incidence rate of the composite endpoint (incidence rate: 11.7/100 person-year versus 23.3/100 person-year, P<0.001). Progression to DD (adjusted HR: 2.014, 95% CI: 1.239–3.273, P=0.005) was independently associated with the composite endpoint. Age (adjusted OR: 1.046, 95% CI: 1.008–1.087, P=0.018), body mass index (BMI) (adjusted OR: 1.107, 95% CI: 1.029–1.192, P=0.006), and serum albumin (adjusted OR: 0.459, 95% CI: 0.216–0.974, P=0.042) were independently associated with progression from ND or ID to DD at 1 year.
Conclusion
More than one-third of patients with HFpEF with ND or ID progressed to DD at 1 year and had poor clinical outcomes. Age, BMI, and serum albumin were independently associated with this progression.

Abstract
Abstract
Background
The effectiveness of angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin II receptor blockers (ARB) has not been demonstrated in patients with heart failure with preserved ejection fraction (HFpEF). We recently reported significant interaction between the use of ACE-I and/or ARB (ACE-I/ARB) and frailty on prognosis in patients with HFpEF.
Purpose
In the present study, we examined the association between ACE-I/ARB and prognosis in patients with HFpEF stratified by the presence or absence of frailty.
Methods
We examined the association between the use of ACE-I/ARB and prognosis according to the presence (Clinical Frailty Scale (CFS) ≥5) or absence (CFS ≤4) of frailty in patients with HFpEF in a post-hoc analysis of registry data. Primary endpoint was the composite of all-cause mortality and heart failure admission. Secondary endpoints were all-cause mortality and heart failure admission.
Results
Of 1059 patients, median age was 83 years and 45% were male. Kaplan-Meier analysis showed that the risk of composite endpoint (log-rank P=0.001) and all-cause death (log-rank P=0.005) in patients with ACE-I/ARB was lower in those with CFS ≥5, but similar between patients with and without ACE-I/ARB in patients with CFS ≤4 (composite endpoint: log-rank P=0.830; all-cause death: log-rank P=0.192). In a multivariable Cox proportional hazards model, use of ACE-I/ARB was significantly associated with lower risk of the composite endpoint (hazard ratio = 0.52, 95% CI: 0.33–0.83, P=0.005) and heart failure admission (hazard ratio = 0.45, 95% CI: 0.25–0.83, P=0.010) in patients with CFS ≥5, but not in patients with CFS ≤4 (composite endpoint: hazard ratio = 1.41, 95% CI: 0.99–2.02, P=0.059; heart failure admission: hazard ratio = 1.43, 95% CI: 0.94–2.18, P=0.091). The association between ACE-I or ARB and prognosis did not significantly differ by CFS (CFS ≤4: log-rank P=0.562; CFS ≥5: log-rank P=0.100, for with ACE-I vs. ARB, respectively). Adjusted HRs for CFS 1–4 were higher than 1.0, but were less than 1.0 at CFS 5.
Conclusions
In patients with HFpEF, use of ACE-I/ARB was associated with better prognosis in patients with frailty as assessed with the CFS, but not in those without frailty.

Abstract
Abstract
Background
Improvement of quality of life (QOL) is one of the most important therapeutic goals for patients with heart failure with preserved ejection fraction (HFpEF). It is, therefore, clinically relevant to comprehensively identify aggravating factors among cardiac factors, non-cardiac comorbidities, and social factors. The aim of this study was to elucidate determinant factors of impaired QOL and clarify the association between QOL and prognosis in patients with HFpEF.
Methods and results
Patient data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study. EuroQol 5 dimensions 5-level (EQ-5D-5L) data were obtained at discharge to evaluate patients' health-related QOL. A total of 864 patients were enrolled in this study. Multivariable logistic regression analysis revealed that only non-cardiac factors such as age, female sex, frailty, malnutrition and inflammation were significantly associated with low EQ-5D-5L score, whereas cardiac factors showed no significant association after multivariable adjustment. A total of 206 patients died over a mean follow-up period of 2.0±1.2 years. Kaplan–Meier survival curve analysis demonstrated a significant increase in risk of mortality stratified by tertiles of EQ-5D-5L score (p<0.0001). Cox multivariable analysis revealed that patients with low EQ-5D-5L score had a significantly greater risk of mortality than those with high EQ-5D-5L score (adjusted hazard ratio: 2.20 (1.40–3.45), p=0.001).
Conclusion
Among patients with HFpEF, non-cardiac factors such as age, female sex, frailty, malnutrition and inflammation are significantly associated with impaired QOL. The QOL score itself also offers useful prognostic information in patients with HFpEF.

Abstract
Abstract
Background
There are several reports showing that elevated heart rate (HR) is associated with poor outcomes in patients in sinus rhythm (SR) with heart failure with preserved ejection fraction (HFpEF), although the association is weak or none in HFpEF patients with atrial fibrillation (Af). However, in previous studies, cardiac and non-cardiac factors which may be associated with elevated HR, have not been fully adjusted for.
Purpose
The purpose of this study is to explore covariates of elevated HR and to investigate the relationship between heart rate and mortality in HFpEF patients in SR.
Methods and results
Of the 1161 patients, who registered prospective multicenter, observational study of patients with HFpEF (PURSUIT-HFpEF), 726 patients in SR were examined. We performed laboratory testing and echocardiography in the compensated stage (in stable condition after treatment of acute decompensated HF). Geriatric nutritional risk index (GNRI) was calculated as nutrition index. Resting heart rate (HR) was analyzed as categorical (tertiles, T1–3). We followed the patients for median of 598 days (interquartile range 329–1028 days) to observe the outcome all-cause mortality.
The Kaplan analysis revealed that there was a significant difference between heart rate and mortality (log-rank, p=0.001). Characteristics were compared between patients in T1 (HR ≤63) and T3 (HR ≥75). There were no differences in cardiac factors between patients in T1 and T3. C-reactive protein (CRP) was significantly higher in patients in T3 than those in T1 (p=0.0004,). GNRI was significantly lower in patients in T3 than those in T1 (p=0.001). After adjustment for covariates including N-terminal pro-B type natriuretic peptide and estimated glomerular filtration rate, CRP and GNRI significantly correlated with HR (continuous variable) by multiple regression analysis (beta-coefficient = 1.52, p=0.003 and beta-coefficient = −0.14, p=0.04, respectively). Taking T1 as the reference, multivariable Cox regression analysis revealed that T3 was independently associated with mortality (hazard ratio: 2.10, 95% confidence interval: 1.33–3.32, p=0.001).
Conclusion
Although elevated HR was associated with enhanced inflammation and malnutrition, it itself was an independent predictor of death in HFpEF patients in SR.

Abstract
Abstract
Background
Malnutrition and inflammation are associated with poor outcomes with heart failure (HF). It has been reported that advanced lung cancer inflammation index (ALI), calculated by body mass index × serum albumin level / neutrophil to lymphocyte ratio (NLR) can be useful for the risk stratification and predicting the post-discharge prognosis of the patients with acute decompensated heart failure (ADHF). However, there is no information available on the prognostic value of the serial ALI change in ADHF patients with preserved ejection fraction (HFpEF).
Methods and results
Patients' data were extracted from The Prospective mUlticenteR obServational stUdy of patIenTs with Heart Failure with Preserved Ejection Fraction (PURSUIT HFpEF) study, which is a prospective multicenter observational registry for ADHF-HFpEF in Osaka. Laboratory data and body weight measurements were performed at the discharge and 1 year after the discharge. We analyzed 527 patients after exclusion of patients on dialysis, in-hospital death, missing follow-up data, or missing data to calculate ALI. The study patients were categorized by the serial change from baseline to 1 year after the discharge (ΔALI) as follows: low tertile: ΔALI <−6.99 (n=176), middle tertile: −6.99 ≤ ALI <8.44 (n=176), and high tertile: 8.44 ≤ ΔALI (n=175). The endpoints of the present study were all-cause death (ACD) and cardiovascular death (CVD). During a mean follow-up period of 1.5±1.0 years, 94 patients had ACD and 40 patients had CVD. The Kaplan-Meier analysis revealed that the patients with middle and low ΔALI at 1 year after heart failure hospitalization had a significantly greater risk of reaching the ACD and CVD than those with high ΔALI (ACD: 22% vs 22% vs 10%, p=0.0011, CVD: 10% vs 9% vs 3%, p=0.014). On multivariate Cox analysis, ΔALI was significantly associated with ACD independently of age, gender, serum NT-proBNP level, and baseline ALI after adjustment for NYHA functional class, serum creatinine level, serum hemoglobin level, serum CRP level, serum sodium level and LVEF.
Conclusion
This study showed that patients with the increased ALI after the discharge had improved outcome in comparison to those without the increased ALI. The serial change of ALI, a systemic inflammation-nutrition index, might be useful for stratifying ADHF patients with HFpEF at risk for the total mortality and cardiovascular mortality.

Abstract
Data capturing multiple axes of tree size and shape, such as a tree's stem diameter, height and crown size, underpin a wide range of ecological research-from developing and testing theory on forest structure and dynamics, to estimating forest carbon stocks and their uncertainties, and integrating remote sensing imagery into forest monitoring programmes. However, these data can be surprisingly hard to come by, particularly for certain regions of the world and for specific taxonomic groups, posing a real barrier to progress in these fields. To overcome this challenge, we developed the Tallo database, a collection of 498,838 georeferenced and taxonomically standardized records of individual trees for which stem diameter, height and/or crown radius have been measured. These data were collected at 61,856 globally distributed sites, spanning all major forested and non-forested biomes. The majority of trees in the database are identified to species (88%), and collectively Tallo includes data for 5163 species distributed across 1453 genera and 187 plant families. The database is publicly archived under a CC-BY 4.0 licence and can be access from: https://doi.org/10.5281/zenodo.6637599. To demonstrate its value, here we present three case studies that highlight how the Tallo database can be used to address a range of theoretical and applied questions in ecology-from testing the predictions of metabolic scaling theory, to exploring the limits of tree allometric plasticity along environmental gradients and modelling global variation in maximum attainable tree height. In doing so, we provide a key resource for field ecologists, remote sensing researchers and the modelling community working together to better understand the role that trees play in regulating the terrestrial carbon cycle.

Abstract
BACKGROUND A 1% potassium peroxymonosulphate-based environmental disinfectant (PPED) produces sodium hypochlorite when combined with sodium chloride, which functions as a disinfectant. However, little is known about the impact of hospital cleaning with PPED on hospital-onset Clostridioides difficile infection (HO-CDI). AIM To reduce HO-CDI, we promote antimicrobial stewardship and hospital ward cleaning with PPED. This study was conducted to evaluate their impact. METHODS We began a promotion of post-prescription review with feedback for broad-spectrum antimicrobials and hospital ward cleaning with PPED. We reviewed the ratio of HO-CDI, PPED consumption, and days of therapy (DOT) of broad-spectrum antimicrobials between July 2014 and March 2018, dividing this time into the pre-promotion (July 2014 to June 2015) and post-promotion periods (July 2015 to March 2018). FINDINGS Using interrupted time series analysis, an immediate significant change in HO-CDI was observed after intervention (P = 0.03), although a downward trend was not observed over this period (P = 0.19). Trends in PPED consumption significantly changed over this period (P = 0.02). DOT of carbapenems decreased immediately after the intervention began (P < 0.01). A Poisson regression analysis showed that PPED consumption and DOT of carbapenems were independent factors affecting HO-CDI (P = 0.039 and 0.016, respectively). CONCLUSION We revealed that DOT of carbapenems and use of PPED were associated with the HO-CDI ratio and that both interventions reduced the rate of HO-CDI. This is the first report on the impact of hospital ward cleaning with PPED on the reduction of HO-CDI.

Abstract
Beta-blocker (BB) use is a mainstay for treatment of heart failure (HF) with reduced ejection fraction (HFrEF), whereas its efficacy for heart failure with preserved ejection fraction (HFpEF) remains controversial. Women outnumber men in HFpEF, whereas men outnumber women in HFrEF. Plasma B-type natriuretic peptide (BNP) is established as a biomarker for HF. We examined whether BB use is associated with plasma BNP levels differently in men and women with HFpEF. The study subjects comprised 721 patients with HFpEF (LVEF≥50%) (184 men, mean age 78.2±9.2 and 537 women, mean age 83.1±8.8), 179 on BB (66 men and 113 women) and 542 (118 men and 424 women) not, 583 in sinus rhythm (SR) and 138 in atrial fibrillation (AF). Multivariable logistic regression test was utilized. Plasma BNP levels were higher (P=0.0005), systolic blood pressure and LVEF lower (P=0.0003, and P=0.0059, respectively) on BBs than on no-BBs in women, whereas in men plasma BNP levels, systolic blood pressure, and LVEF were not altered significantly (P=0.0849, P=0.9129, and P=0.4718, respectively) on BBs compared to no-BBs in patients with SR. Multivariable logistic regression analysis revealed that BB use and women were a positive and a negative predictor for high BNP levels (P=0.003 and P=0.032, respectively) in SR but not in AF. BB use was associated with high plasma BNP levels and lower LVEF in women but not in men with HFpEF and SR, suggesting that the pathogenesis and of HFpEF may differ in men and women in SR.

Abstract
AIMS It has been reported that a staging system combining N-terminal pro-B-type natriuretic peptide and high-sensitivity troponin T (hs-cTnT) or estimated glomerular filtration rate (eGFR) is useful in patients with wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM). However, these studies were mainly conducted in Western countries, and their usefulness for the Japanese population is unclear. We examined and validated the staging system using hs-cTnT, eGFR, and B-type natriuretic peptide (BNP) in Japanese patients with ATTRwt-CM. METHODS AND RESULTS We retrospectively evaluated 176 patients with ATTRwt-CM. The cut-off values of hs-cTnT and eGFR were selected as 0.05 ng/mL and 45 mL/min/1.73 m2 , respectively, based on a previous report. The optimal cut-off value of BNP was 255.6 pg/mL to predict all-cause mortality (sensitivity, 75%; specificity, 58%; area under the curve, 0.69; 95% confidence interval [CI], 0.61-0.78; P < 0.001) based on a receiver operating characteristic curve. We defined the cut-off value of BNP as 250 pg/mL. Increased hs-cTnT (>0.05 ng/mL) and BNP (>250 pg/mL) and decreased eGFR (<45 mL/min/1.73 m2 ) were significant predictors of poor prognosis (P < 0.05). We calculated the score by adding 1 point if hs-cTnT and BNP levels increased or eGFR decreased by more than the cut-off value. The hazard ratio of all-cause death adjusted by age and sex, using score 0 as a reference, was 0.44 (95% CI 0.08-2.49, P = 0.44) for score 1, 3.69 (95% CI 1.21-11.21, P = 0.02) for score 2, and 5.40 (95% CI 1.57-18.54, P = 0.007) for score 3. We divided patients into a low score group (0-1 point) and high score group (2-3 points). Kaplan-Meier analyses revealed significant differences in all-cause death and rehospitalization for heart failure (log rank test; P < 0.001), and after adjusting for sex and age, the hazard ratio of all-cause death was 6.96 (95% Cl 2.88-16.83, P < 0.001) and that for rehospitalization for heart failure was 4.27 (95% Cl 2.26-8.07, P < 0.001) in the high-risk group, compared with those in the low-risk group. The median survival period was 32.0 months in the high-risk group. CONCLUSIONS This simple staging system, which combines hs-cTnT, BNP, and eGFR, was useful for predicting prognosis in Japanese patients with ATTRwt-CM. This system can objectively evaluate the disease progression of ATTRwt-CM and may be useful for patient selection for disease-modifying therapy.

Abstract
Diabetic nephropathy, included in diabetic kidney disease (DKD), is the primary disease leading to end-stage renal disease (ESRD) or dialysis treatment, accounting for more than 40% of all patients with ESRD or receiving dialysis. Developing new therapeutics to prevent the transition to ESRD or dialysis treatment requires an understanding of the pathophysiology of DKD and an appropriate animal model for drug efficacy studies. In this study, we investigated the pathophysiology of diabetic kidney disease with type 2 diabetes in uninephrectomized db/db mice. In addition, the nephrectomized db/db mice from 10 weeks to 42 weeks were used to assess the efficacy of long-term administration of the angiotensin-II–receptor antagonist losartan. The blood and urinary biochemical parameters and the blood pressure which is a main pharmacological endpoint of the losartan therapy, were periodically measured. And at the end, histopathological analysis was performed. Uninephrectomized db/db mice clearly developed obesity and hyperglycemia from young age. Furthermore, they showed renal pathophysiological changes, such as increased urinary albumin-creatinine ratio (UACR) (the peak value 3104±986 in 40-week-old mice), glomerular hypertrophy and increased fibrotic areas in the tubulointerstitial tubules. The blood pressure in the losartan group was significantly low compared to the normotensive Vehicle group. However, as expected, Losartan suppressed the increase in UACR (829±500) indicating the medication was sufficient, but the histopathological abnormalities including tubular interstitial fibrosis did not improve. These results suggest that the uninephrectomized db/db mice are useful as an animal model of the severe DKD indicated by the comparison of the efficacy of losartan in this model with the efficacy of losartan in clinical practice.

Abstract
The Hayabusa2 spacecraft investigated the C-type (carbonaceous) asteroid (162173) Ryugu. The mission performed two landing operations to collect samples of surface and subsurface material, the latter exposed by an artificial impact. We present images of the second touchdown site, finding that ejecta from the impact crater was present at the sample location. Surface pebbles at both landing sites show morphological variations ranging from rugged to smooth, similar to Ryugu's boulders, and shapes from quasi-spherical to flattened. The samples were returned to Earth on 6 December 2020. We describe the morphology of >5 grams of returned pebbles and sand. Their diverse color, shape, and structure are consistent with the observed materials of Ryugu; we conclude that they are a representative sample of the asteroid.

Abstract
In semiconductor device history, a trend is observed where narrowing and increasing the number of material layers improve device functionality, with diodes, transistors, thyristors, and superlattices following this trend. While superlattices promise unique functionality, they are not widely adopted due to a technology barrier, requiring advanced fabrication, such as molecular beam epitaxy and lattice-matched materials. Here, a method to design quantum devices using amorphous materials and physical vapor deposition is presented. It is shown that the multiplication gain M depends on the number of layers of the superlattice, N, as M = kN, with k as a factor indicating the efficiency of multiplication. This M is, however, a trade-off with transit time, which also depends on N. To demonstrate, photodetector devices are fabricated on Si, with the superlattice of Se and As2Se3, and characterized using current-voltage (I-V) and current-time (I-T) measurements. For superlattices with the total layer thicknesses of 200 nm and 2 μm, the results show that k200nm = 0.916 and k2μm = 0.384, respectively. The results confirm that the multiplication factor is related to the number of superlattice layers, showing the effectiveness of the design approach.

Abstract
The fossil record of terrestrialization documents notable shifts in the environmental and physiological tolerances of many animal and plant groups. However, for certain significant components of modern freshwater and terrestrial environments, the transition out of marine settings remains largely unconstrained. Ostracod crustaceans occupy an exceptional range of modern aquatic environments and are invaluable palaeoenvironmental indicators in the fossil record. However, pre-Carboniferous records of supposed non-marine and marginal marine ostracods are sparse, and the timing of their marine to non-marine transition has proven elusive. Here, we reassess the early environmental history of ostracods in light of new assemblages from the late Silurian of Vietnam. Two, low diversity but distinct ostracod assemblages are associated with estuarine deposits. This occurrence is consistent with previous incidental reports of ostracods occupying marginal and brackish settings through the late Silurian and Devonian. Therefore, ostracods were pioneering the occupation of marginal marine and estuarine settings 60 Myr before the Carboniferous and they were a component of the early phase of transition from marine to non-marine environments.

Abstract
Background
Concomitant presence of pulmonary hypertension in heart failure (HF) is associated with increased adverse events and may be related to interventricular uncoupling and impaired cardiac efficiency. It has recently been shown that an increased mean pulmonary artery pressure to mean systemic arterial pressure ratio (MPS ratio), a marker of interventricular coupling and efficiency, is associated with worse clinical outcomes in patients with advanced HF. On the other hand, systemic inflammation plays a critical role in the outcomes of heart failure, and malnutrition is also associated with poor outcome in heart failure patients It has been recently reported that advanced lung cancer inflammation index (ALI), which is calculated as body mass index × serum albumin / neutrophil to lymphocyte ratio (NLR), is an independent prognostic marker in several types of cancer. However, there is no information available on the prognostic value of the combination of MPS ratio and ALI in patients with acute decompensated HF (ADHF).
Methods and results
We studied 219 patients admitted for ADHF, who underwent right heart catheterization at the admission and were discharged with survival. During a follow up period of 5.1±4.2 yrs, 57 had cardiovascular death (CVD). MPS ratio was significantly greater (0.401±0.107 vs 0.346±0.105, p=0.0009) and ALI was significantly smaller (34.2±18.7 vs 52.0±27.1, p<0.0001) in patients with than without CVD At multivariate Cox analysis, MPS ratio and ALIwere significantly associated with CVD, independently of eGFR and prior heart failure hospitalization, after the adjustment with left ventricular end-diastolic dimension and serum sodium level. The patients with both greater MPS ratio>0.350 (AUC 0.652 [0.569–0.735]) and smaller ALI <35.767 (AUC 0.714 [0.636–0.792]) had a significantly increased risk of CVD than those with either greater MPS or smaller ALI and none of them (67% vs 22% vs 11%, p<0.0001, respectively).
Conclusion
The combination of MPS ratio and ALI might be useful for stratifying ADHF patients at higher risk for CVD.

Abstract
Abstract
Background
Clinical heterogeneity exists in heart failure with preserved ejection fraction (HFpEF). Left ventricular (LV) structure in HFPEF is characterized by normal LV cavity size and LV hypertrophy (LVH). However some of HFPEF patients do not have LV hypertrophy, and these patients may have distinct characteristics,
Purpose
The purpose of this study is to clarify the clinical characteristics and the prognosis for HFPEF patients without LVH.
Methods
We studied 1097 patients, who were hospitalized for acute decompensated heart failure with LVEF ≥50%, and enrolled in the PURSUIT-HFpEF registry. Laboratory testing and echocardiography were examined in the compensated stage (in stable condition after treatment of acute decompensated HF). We divided these patients into 2 groups based on LV mass index (LVMI) in the compensated stage according to the American Society of Echocardiography/European Association of Cardiovascular Imaging recommendations; patients with LVH (48%) and those without LVH (52%).
Results
Patients without LVH had significantly lower levels of C-reactive protein and N-terminal pro brain natriuretic peptide (NT-proBNP) and higher levels of estimated glomerular filtration rate in the compensated stage than those with it (p<0.05 for all). Cox hazard regression analysis showed that absence of LVH was favorably associated with the primary composite endpoint of all-cause death, HF rehospitalization, and cerebrovascular events (hazard ratio 0.776, 95% confidence interval 0.620-to 0.970, p<0.05).
On the other hand, the frequency of atrial fibrillation (Af) in the decompensated stage was higher in patients without LVH than those with it (52.1% vs 39.3%, p<0.001). Multivariate logistic analysis showed that absence of LVH was independently associated with presence of Af in the decompensated stage (odds ratio=1.520, 95% confidence interval 1.130 to 2.050, P<0.01)
Conclusions
HFPEF patients without LVH have less organ damage and favorable prognosis. Af may play a role in the decompensation of HF in HFPEF patients without LVH.

Abstract
Aims
A significant male predominance has been reported in wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM). In other words, the female ATTRwt-CM may be overlooked and gender differences in ATTRwt-CM remain unclear. This study aims to examine gender differences in clinical characteristics and diagnostic approaches in ATTRwt-CM.
Methods and results
We retrospectively evaluated 171 consecutive ATTRwt-CM patients diagnosed at our university hospital between December 2002 and December 2020. Twenty-two patients (12%) were women. Women were significantly older at diagnosis (77.3 years vs. 83.3 years; P<0.001) and had a higher advanced New York Health Association functional class (2.23±0.70 vs. 2.57±0.81; P=0.04) than men. In echocardiography, mean interventricular septum diameter was less thick (15.8 mm vs. 14.5 mm; P=0.03) and ejection fraction was preserved (51.7% vs. 57.7%; P=0.08) in women. The mean heart-to-contralateral ratio obtained using 99mTc-labeled pyrophosphate (99mTc-PYP) was significantly lower in women than in men (1.89 vs. 1.64; P=0.001). There was no significant gender difference in high-sensitivity median cardiac troponin T levels at diagnosis (0.055 ng/mL vs. 0.069 ng/mL; P=0.30) or history of carpal tunnel syndrome (57% vs. 55%; P=0.93) and electrocardiograms findings. However, the median B-type natriuretic peptide level was significantly higher (254 pg/mL vs. 434 pg/mL; P=0.02) in women. Moderate to severe aortic stenosis was more frequently observed in women (5% vs. 50%; P<0.001). Histological (78% vs. 59%; P=0.07) and genetic confirmation (78% vs. 59%; P=0.003) of ATTRwt-CM were not performed in women.
Conclusion
Women with ATTRwt-CM were predominantly octogenarians, less hypertrophic, and had weaker cardiac uptake of the 99mTc-PYP tracer than men with ATTRwt-CM. These characteristics contribute to the underdiagnosis of ATTRwt-CM in women. The diagnosis of ATTRwt-CM in women is challenging. Therefore, we must be familiar with the clinical characteristics of women with ATTRwt-CM.

Abstract
Abstract
Background
Sarcopenia and malnutrition are associated with poor clinical outcome in patients with chronic heart failure. However, there is little information available on the prognostic significance of the combination of sarcopenia and malnutrition in patients with acute decompensated heart failure (ADHF), relating to reduced or preserved left ventricular ejection fraction (HFrEF or HFpEF).
Methods
We prospectively studied 543 consecutive ADHF patients who survived to discharge (HFrEF [LVEF <45%] n=245 and HFpEF [LVEF≥45%] n=298). At the discharge, sarcopenia and malnutrition was evaluated by free-fat mass index (FFMI) and geriatric nutrition risk index (GNRI), respectively. FFMI was calculated as follows: FFMI = (7.38 + 0.02908 × urinary creatinine [mg/day])/ (height in meter)2. Sarcopenia was defined as FFMI <17 kg/m2 in men and <15 kg/m2 in women. GNRI was calculated as follows: 14.89 × serum albumin (g/dl) + 41.7 × BMI/22, and malnutrition was defined as GNRI<92. The endpoint was all-cause death.
Results
During a follow-up period of 2.8±1.4 years, 161 patients had all-cause death. Multivariate Cox analysis showed that both FFMI and GNRI were independently associated with all-cause death in both HFrEF (p=0.0064 and p<0.0001, respectively) and HFpEF patients (p=0.0140 and p=0.0007, respectively) after adjustment for relevant baseline clinical and study characteristics. In HFrEF, patients with both sarcopenia and malnutrition had a significantly higher risk of the total mortality than those with either or none of them. On the other hand, in HFpEF, patients with both and either sarcopenia or malnutrition had a significantly higher risk of the total mortality than those with none of them, while there was no significant difference in the risk between both and either sarcopenia or malnutrition.
Conclusions
Sarcopenia or malnutrition at discharge was associated with all-cause death even in ADHF patients, irrespective of reduced or preserved LVEF. The combination of sarcopenia and malnutrition could provide prognostic information in ADHF 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.

Abstract
Abstract
Background
Increased heart rate (HR) and low systolic blood pressure (SBP) are associated with adverse clinical outcomes in patients admitted for acute decompensated heart failure (ADHF), and simple risk index (SRI) based on easily assessed clinical characteristics (age, HR, and SBP) provides prognostic information. On the other hand, plasma volume (PV) expansion plays an essential role in heart failure, and PV status is has been reported to be associated with adverse outcomes in ADHF patients. However, there is no information available on the value of the combination of SRI and PV status in patients admitted for ADHF.
Methods and results
We studied 301 patients admitted for ADHF. At the admission, SRI was calculated as (HR x [age/10]2)/SBP. PV status was calculated as the following: Actual PV = (1 − hematocrit) x [a + (b x body weight)] (a=1530 in males and a=864 in females, b=41 in males and b=47.9 in females), Ideal PV = c x body weight (c=39 in males and c=40 in females), and PV status = [(actual PV − ideal PV)/ideal PV] x 100(%). During a follow-up period of 4.3±3.2 yrs, 95 patients had all-cause death (ACD) and 68 patients had cardiovascular death (CVD). At multivariate Cox analysis, SRI and PV status were significantly associated with ACD and CVD, independently of the prior history of heart failure hospitalization and serum creatinine and sodium levels, after the adjustment with serum albumin level and anemia. Patients with both greater SRI (≥35.1 by ROC analysis; AUC 0.599 [0.524–0.674]) and greater PV status (≥8.1% by ROC analysis; AUC 0.625 [0.550–0.700]) had a significantly higher risk of ACD and CVD than those with either or none of them (ACD: 49% vs 27% vs 24%, p<0.0001, CVD: 39% vs 18% vs 15%, p<0.0001,respectively).
Conclusion
The combination of SRI and PV status might be useful for stratifying patients at risk for the total mortality and cardiovascular death in patients with ADHF.

Abstract
Abstract
Background
Patients with acute myocardial infarction (AMI) who require extracorporeal membrane oxygenation (ECMO) have worse outcomes than those who do not, and patients with AMI with out-of-hospital cardiac arrest (OHCA) also have worse outcomes than those without OHCA. However, there have been still unclear points regarding the prognostic factors of AMI patients who underwent ECMO with or without OHCA. The aim of this study was to investigate the prognostic factors of AMI patients who underwent ECMO with and without OHCA, respectively.
Methods/Results
Ninety-eight consecutive patients (age:67±11 years, male:83.7%) who underwent ECMO for AMI were enrolled from November 2008 to December 2020. The primary endpoint was in-hospital mortality within 30-day, and we investigated the risk factors associated with 30-day mortality in AMI patients underwent ECMO with or without OHCA, respectively. In the group with OHCA (n=47), 30-day death occurred in 22 patients (47%). BMI, lactate and serum creatinine levels after the introduction of ECMO were significantly greater in patients with than without 30-day death (27.0±5.2 vs 21.0±2.9 kg/m2, p<0.001, 12.1±4.3 vs 7.5±3.6 mmol/L, p<0.001, 1.68±1.24 vs 1.41±1.07 mg/dL, p=0.039, respectively). The multivariate regression analysis showed that lactate level was independently associated with the poor outcome (Odds ratio: 1.32, 95% CI: 1.11–1.57, p<0.001). ROC curve analysis showed that the cut-off values: 7.8mmol/L of lactate had moderate accuracy to predict 30-day mortality (sensitivity:76%, specificity:86%, AUC:0.81). In the group without OHCA (n=51), 30-day death occurred in 20 patients (39%). The frequency of ventricular tachycardia / fibrillation (VT/VF) at initiation of ECMO was significantly higher (61.3% vs 25.0%, p=0.021), the frequency of mechanical complication was significantly lower (6.5% vs 30.0%, p=0.045) in patients without 30-day death than with 30-day death. The multivariate regression analysis showed that VT/VF at initiation of ECMO was independently associated with good outcome (Odds ratio: 0.21, 95% CI: 0.06–0.73, p=0.01).
Conclusions
With OHCA, increased lactate was the risk factor that was significantly associated with poor outcome in AMI patients underwent ECMO. Without OHCA, AMI patients who underwent ECMO due to rhythm trouble such as VT/VF had a good outcome. ECMO patients with AMI may have different prognostic factors with or without OHCA.

Abstract
Abstract
Background
Functional mitral regurgitation (FMR) is not uncommon in atrial fibrillation (AF) patients. Left atrial (LA) substrate remodeling and corresponding mitral valve annulus dilation has been reported as the most possible cause of FMR. Percutaneous catheter ablation (CA) is an effective treatment for AF. Although significant FMR could be improved by sinus restoration, patients with mitral regurgitation were more likely to experience recurrent AF post ablation, especially those with significant mitral regurgitation. There is no information available on the efficacy of CA for persistent AF in patients with FMR.
Purpose
The purpose of this study is to investigate the predictors of FMR improvement by CA and to determine the efficacy of substrate and trigger CA for persistent AF in patients with FMR.
Methods
We prospectively studied 512 consecutive patients admitted for persistent AF ablation from the EARNEST-PVI (Prospective Multicenter Randomized Study of Effect of Extensive Ablation on Recurrence in Patients with Persistent Atrial Fibrillation Treated with Pulmonary Vein Isolation) trial.
On admission, enrolled patients were randomly assigned in a 1:1 ratio to pulmonary vein isolation (PVI) or PVI-plus additional ablation (linear ablation or/and CFAE ablation). Of the 512 patients, we studied 94 patients with preoperative echocardiography showing moderate or greater baseline FMR. FMR grades were classified into 5 grades (0/1/2/3/4). The FMR improvement group (FMRI(+)) was defined as a case in which the FMR was improved by two or more grades compared the preoperative echocardiography and the one year follow-up examination.
Results
Of the 94 patients, 42 were in the PVI group and 52 were in the PVI-plus additional ablation group. There were 30 cases in the FMRI(+) group and 64 cases in the FMRI(−) group. There were no significant baseline differences in age, sinus rhythm maintenance, plasma B-type natriuretic peptide (BNP) level, left ventricular diastolic dimension, or left atrium dimension between the FMRI(+) and FMRI(−) groups. AF duration was significantly shorter in the FMRI(+) group than FMRI(−) groups (5.8±9.4 months vs 12.4±15.4 months, p<0.0001). In addition, significantly more additional ablation cases were observed in the FMRI(+) group than in the FMRI(−) group (73.3% vs 46.8%, p=0.016). In multivariate analyses, only additional ablation was an independent predictor of FMRI (odds ratio 0.226 95% CI 0.081–0.626; p=0.004).
Conclusions
Catheter ablation is a valid option for the treatment of AF in patients with functional MR and additional substrate and trigger ablation were the only independent predictor of FMR improvement.

Abstract
Abstract
Background
Systemic inflammation plays a critical role in the outcomes of heart failure. Malnutrition is also associated with poor outcome in heart failure patients. It has been recently reported that advanced lung cancer inflammation index (ALI), which is calculated as body mass index × serum albumin / neutrophil to lymphocyte ratio (NLR), is an independent prognostic marker in several types of cancer. However, there is no information available on the prognostic impact of ALI in patients admitted with acute decompensated heart failure (ADHF), especially in comparison with malnutrition.
Methods and results
We studied 263 ADHF patients discharged with survival. At the discharge, we measured ALI. Malnutrition was assessed by prognostic nutritional index (PNI) and controlling nutritional status score (CONUT). During a follow up period of 5.1±4.3 yrs, 67 patients had cardiovascular death (CVD). ALI was significantly smaller in patients with than without CVD (32.5±18.2 vs 52.2±30.2, p<0.0001). At multivariate Cox regression analysis, ALI was significantly associated with CVD, independently of prior heart failure hospitalization, systolic blood pressure and eGFR, although PNI and CONUT showed the association with CVD at unvariate analysis. By receiver-operator curve analysis, AUC of ALI was 0.733 (0.664–0.803), which was significantly greater than that of PNI (0.664 [0.590–0.739]) and CONUT (0.591 [0.509–0.672]). Patients with lowest tertile of ALI (<32.0) had a increased risk of mortality than middle tertile (NLR=32.0–53.6; HR 2.06 [1.15–3.71]) and highest tertile (ALI>53.6: HR 5.80 [2.60–12.94]) (48% vs 21% vs 9%, p<0.0001, respectively).
Conclusion
ALI, a systemic inflammation-nutrition index, is more useful prognostic marker than malnutrition in patients admitted with ADHF.

Abstract
Abstract
Background
Malnutrition is associated with increased mortality risk in patients with acute decompensated heart failure (ADHF). Cardiohepatic interactions have been a focus of attention among heart failure. It was reported that liver stiffness assessed by non-invasive fibrosis marker such as Fibrosis-4 (FIB4) index provide prognostic information in ADHF patients. However, there is no information available on the long-term prognostic value of the combination of malnutrition and FIB4 index in patients admitted for ADHF.
Methods and results
We studied 294 patients admitted for ADHF, who were discharged with survival. Nutritional status was evaluated by Geriatric Nutritional Risk Index (GNRI) calculated as follows: 14.89 × serum albumin (g/dl) + 41.7 × BMI/22, and malnutrition was defined as GNRI <92. FIB4 index was calculated by the formula: age (yrs) × AST[U/L] / (platelets [103/μL] × (ALT[U/L])1/2), and abnormal FIB4 index was defined as >2.67. During a mean follow-up period of 4.3±3.3 yrs, 94 patients had all-cause death. At multivariate Cox regression analysis, GNRI and FIB4 index were significantly associated with the total mortality, independently of prior heart failure hospitalization, systolic blood pressure, and serum creatinine level. Patients with malnutrition and abnormal FIB4 index had a significantly higher risk of the total mortality than those with either and none of them (49% vs 32% vs 20%, p<0.0001, respectively).
Conclusions
The combination of malnutrition and FIB4 index might be useful for stratifying ADHF patients at higher risk for the total mortality.

Abstract
Aims This study was performed to investigate whether left atrial (LA) strain by echocardiography provides prognostic information in patients with wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM). Methods and results Among 129 patients who were diagnosed with ATTRwt‐CM at Kumamoto University Hospital from December 2002 to December 2019, 113 patients who had enough information for two‐dimensional speckle tracking echocardiography were enrolled in this study. During a median follow‐up of 668 days, 28 cardiovascular deaths occurred. Compared with patients in the non‐event group, those in the cardiovascular death group were significantly older (81.5 ± 7.4 vs. 78.1 ± 6.1 years, P < 0.01), had a lower incidence of carpal tunnel syndrome (21% vs. 47%, P < 0.05), and had a higher high‐sensitivity cardiac troponin T [0.085 (0.063–0.105) vs. 0.049 (0.036–0.079) ng/mL, P < 0.01] and B‐type natriuretic peptide concentrations [419 (239–541) vs. 271 (155–462) pg/mL, P < 0.01] and lower estimated glomerular filtration rate (41.8 ± 15.4 vs. 53.4 ± 14.6 mL/min/1.73 m2, P < 0.01). Electrocardiography showed higher rate of a V1–V3 QS pattern (52% vs. 24%, P < 0.01) and complete left bundle branch block (27% vs. 6%, P < 0.01), and echocardiography showed a significantly lower peak LA strain rate during the contraction phase (0.16 ± 0.13 vs. 0.28 ± 0.27 S−1, P < 0.05), LA strain during the reservoir phase (LASr) (5.84 ± 2.41 vs. 8.22 ± 4.05%, P < 0.01), and peak LA strain rate during the reservoir phase (0.26 ± 0.09 vs. 0.33 ± 0.15 S−1, P < 0.05) in the cardiovascular death group than in non‐event group. By contrast, conventional echocardiographic findings were not significantly different between these two groups. After adjusting for conventional predictive factors of ATTRwt‐CM (age, high‐sensitivity cardiac troponin T and B‐type natriuretic peptide concentrations, and estimated glomerular filtration rate), multivariable Cox proportional hazard analyses showed that LASr was significantly and independently associated with cardiovascular death in patients with ATTRwt‐CM (odds ratio, 0.84; 95% confidence interval, 0.72–0.98; P < 0.05). After adjusting for age and echocardiographic findings associated with cardiovascular death (LA volume index and peak LA strain rate during the contraction phase), LASr was significantly and independently associated with cardiovascular death in patients with ATTRwt‐CM (odds ratio, 0.83; 95% confidence interval, 0.70–0.98; P < 0.05). Receiver operating characteristic curve analysis showed that the area under the curve of LASr for cardiovascular death was 0.686 and that the best cut‐off value of LASr was 6.69% (sensitivity, 62.4%; specificity, 64.3%). In the Kaplan–Meier analysis, patients with low LASr (<6.69%) had a significantly higher probability of total cardiovascular death (P < 0.05) and heart failure‐related hospitalization (P < 0.05). Conclusions Left atrial strain during the reservoir phase provides significant prognostic value in patients with ATTRwt‐CM even after adjusting for conventional predictive factors.

Abstract
Background Cardiac fibrosis plays a crucial role in the pathogenesis of dilated cardiomyopathy (DCM). HE4 (human epididymis protein 4) is a secretory protein expressed in activated fibroblasts that exacerbates tissue fibrosis. In the present study, we investigated the clinical utility of HE4 measurement in patients with DCM and its pathophysiological role in preclinical experiments in vivo and in vitro. Methods and Results We measured serum HE4 levels of 87 patients with DCM. Endomyocardial biopsy expressed severe fibrosis only in the high HE4 group (P<0.0001). Echocardiography showed that left ventricular end‐diastolic diameter tends to decrease over time (58±7.3 to 51±6.6 mm; P<0.0001) in the low HE4 group (<59.65 pmol/L [median value]). HE4 was significantly associated with risk reduction of mortality and cardiovascular hospitalization in multivariate Cox model. In vivo, HE4 was highly expressed in kidney and lung tissue of mouse, and scarcely expressed in heart. In genetically induced DCM mouse model, HE4 expression increased in kidney but not in heart and lung. In vitro, supernatant from HE4‐transfected human embryonic kidney 293T cells enhanced transdifferentiation of rat neonatal fibroblasts and increased expression of fibrosis‐related genes, and this was accompanied by the activation of extracellular signal‐regulated kinase signaling in cardiac fibroblasts. Treatment with an inhibitor of upstream signal of extracellular signal‐regulated kinase or a neutralizing HE4 antibody canceled the profibrotic properties of HE4. Conclusions HE4 functions as a secretory factor, activating cardiac fibroblasts, thereby inducing cardiac interstitial fibrosis. HE4 could be a promising biomarker for assessing ongoing fibrosis and a novel therapeutic target in DCM.
