Abstract
OBJECTIVES The high rate of delayed bleeding after colorectal endoscopic submucosal dissection (ESD) in patients undergoing anticoagulant therapy remains a problem. Whether prophylactic clip closure reduces the rate of delayed bleeding in these patients is unclear. This study aimed to evaluate the efficacy of prophylactic clip closure in patients receiving anticoagulants. METHODS This multicenter prospective interventional trial was conducted at nine referral centers in Japan. Patients regularly taking anticoagulants, including warfarin potassium or direct oral anticoagulants, and undergoing ESD for colorectal neoplasms were enrolled. The discontinuation of anticoagulants was minimized according to recent guidelines. After the ESD, post-ESD ulcers were prophylactically closed using endoclips. The primary end-point was the incidence of delayed bleeding. The sample size was 45 lesions, and prophylactic clip closure was considered effective when the upper limit of the 90% confidence interval (CI) for delayed bleeding did not exceed 20%. RESULTS Forty-five lesions were used, and three were excluded. Complete closure was achieved in 41/42 lesions (97.6%). The overall delayed bleeding rate was low, at 4.9% (2/41; 90% [CI] 0.8-14.5), which was significantly lower than that at the prespecified threshold of 20% (P = 0.007). The median closure procedure time was 17 min, and the median number of clips was nine. No massive delayed bleeding requiring transfusion, interventional radiology, or surgery was observed, and no thromboembolic events were observed. CONCLUSION Prophylactic clip closure may reduce the risk of delayed bleeding following colorectal ESD in patients receiving anticoagulants.

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
INTRODUCTION We aimed to evaluate the natural course of sporadic nonampullary duodenal adenomas (SNDAs) and determine the risk factors of progression. METHODS We retrospectively analyzed the follow-up outcomes of patients with biopsy-diagnosed SNDA between April 2010 and March 2016 at 13 institutions. All initial biopsy specimens were centrally evaluated. Only those diagnosed with adenomas were included. Mucinous phenotypes were classified into pure intestinal and non-pure intestinal phenotypes. Cumulative incidence rates of carcinoma and tumor enlargement were evaluated. Tumor enlargement was defined as a ≥25% or 5-mm increase in tumor size. RESULTS Overall, 121 lesions were analyzed. Within a median observation period of 32.7 months, 5 lesions were diagnosed as carcinomas; the cumulative 5-year incidence of carcinoma was 9.5%. Male sex ( P = 0.046), initial lesion size ≥10 mm ( P = 0.044), and non-pure intestinal phenotype ( P = 0.019) were significantly associated with progression to carcinoma. Tumor enlargement was observed in 22 lesions, with a cumulative 5-year incidence of 33.9%. Initial lesion size ≥10 mm ( P < 0.001), erythematous lesion ( P = 0.002), high-grade adenoma ( P = 0.002), Ki67 negative ( P = 0.007), and non-pure intestinal phenotype ( P = 0.001) were risk factors of tumor enlargement. In a multivariate analysis, an initial lesion size ≥10 mm ( P = 0.010) and non-pure intestinal phenotype ( P = 0.046) were independent and significant risk factors of tumor enlargement. DISCUSSION Lesion size ≥10 mm and non-pure intestinal phenotype on initial biopsy are risk factors of cancer progression and tumor enlargement in cases with SNDA. Thus, management effectiveness may be improved by focusing on lesion size and the mucinous phenotype.

Abstract
Background and Aim Recently, the use of various endoscopic procedures performed under X-ray fluoroscopy guidance has increased. With the popularization of such procedures, diagnostic reference levels (DRLs) have been widely accepted as the global standard for various procedures with ionizing radiation. The Radiation Exposure from Gastrointestinal Fluoroscopic Procedures (REX-GI) study aimed to prospectively collect actual radiation exposure (RE) data and establish DRLs in gastrointestinal endoscopy units. In this post hoc analysis of the REX-GI study, we established DRLs for each disease site by analyzing cases of gastrointestinal enteral metallic stent placement. Methods The REX-GI study was a multicenter, prospective observational study conducted to collect actual RE data during gastrointestinal enteral metallic stent placement. To establish DRL values for three disease sites, namely the esophagus, gastroduodenum, and colon, we examined fluoroscopy time (FT; min), number of X-ray images, air kerma at the patient entrance reference point (K a,r; mGy), and the air kerma-area product (P KA; Gy cm2) during enteral metallic stent placement. Results Five-hundred and twenty-three stenting procedures were performed. The DRL values of FT (min) and the number of X-ray images for the esophagus/gastroduodenum/colon were 9/16/18 min and 9/15/11 min, respectively. Furthermore, the DRL values of K a,r and P KA for each disease site were 43.3/120/124 mGy and 10.3/36.6/48.4 Gy cm2, respectively. Among the procedures, esophageal stents were significantly associated with the lowest values (P < 0.001). Conclusion The characteristics of RE vary according to disease site among gastrointestinal enteral metallic stent placements. Thus, it is desirable to set DRL values based on the disease site.

Abstract
Objectives Japan has a high prevalence of low back pain among older adults requiring long-term care, which results in increasing expenses; therefore, prevention measures are necessary. This study aimed to examine the relationship between low back pain and physical activity and sitting time according to sex and age (65-74 years [young-old adults]; ≥75 years [old-old adults]) who had not received long-term care certification.Methods A self-administered survey was mailed to 7,080 adults >65 years of age residing in Tsuru City (Yamanashi Prefecture, Japan) from January to February 2018, and had not received long-term care certification. Demographic information, health status (body mass index and medical history), lifestyle (dietary habits, alcohol consumption, and smoking), presence of low back pain, physical activity, sitting time, and social participation were measured. Low back pain was evaluated by asking, "Did you experience pain in parts of the body other than the knees for the past month?" Those who answered, "experienced low back pain" were categorized as "with low back pain". The short form of the International Physical Activity Questionnaire was used to assess physical activity, which was categorized into three groups: <150, 150-299, and ≥300 min/week. Sitting time was divided into two groups: <480 and ≥480 min/day. Multiple logistic regression analysis was used to determine the association between low back pain and physical activity and sitting time, according to sex and age.Results Of the 7,080 individuals surveyed, 4,877 responded (2,217 male, 2,660 female), corresponding to a response rate of 68.9%. The number of older adults with low back pain was 1,542 (31.6%) including 673 (30.4%) males and 869 (32.7%) females. The rate of low back pain in young-old adults was 29.8% and 33.6% in old-old adults. There was no significant relationship between lower back pain and physical activity among the young-old adults. In the old-old adults, there was a significant relationship in the male ≥300 min group (odds ratio [OR] 0.66 [95%CI 0.48-0.89]), and in both female 150-299 (OR 0.69 [95%CI 0.48-0.99]) and ≥300 (OR 0.59 [95%CI 0.44-0.80]) min/week groups.Conclusion The complaint rate for low back pain was approximately 30%, regardless of sex or age. These results suggest that interventions to prevent low back pain are necessary. Moreover, physical activity, but not sitting time, was associated with low back pain in both males and females among the old-old adults.

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
The NAM, ATAF1/2, and CUC2 (NAC) domain transcription factor VND-INTERACTING2 (VNI2) negatively regulates xylem vessel formation by interacting with another NAC domain transcription factor, VASCULAR-RELATED NAC-DOMAIN7 (VND7), a master regulator of xylem vessel formation. Here, we screened interacting proteins with VNI2 using yeast two-hybrid assay and isolated two NAC domain transcription factors, Arabidopsis thaliana ACTIVATION FACTOR 2 (ATAF2) and NAC DOMAIN CONTAINING PROTEIN 102 (ANAC102). A transient gene expression assay showed that ATAF2 upregulates the expression of genes involved in leaf senescence, and VNI2 effectively inhibits the transcriptional activation activity of ATAF2. vni2 mutants accelerate leaf senescence, whereas ataf2 mutants delay leaf senescence. In addition, the accelerated leaf senescence phenotype of the vni2 mutant is recovered by simultaneous mutation of ATAF2. Our findings strongly suggest that VNI2 interacts with and inhibits ATAF2, resulting in negatively regulating leaf senescence.

Abstract
Anginosus group streptococci (AGS) are opportunistic human pathogens of the oral cavity. The β-hemolytic subgroup of Streptococcus anginosus subsp. anginosus secretes streptolysin S (SLS) and exhibits not only hemolytic activity but also cytotoxicity toward cultured human cell lines. However, the detailed mechanism of action of SLS and the cellular responses of host cells have not yet been fully clarified. To determine the pathogenic potential of SLS-producing β-hemolytic S. anginosus subsp. anginosus, the SLS-dependent response induced in the human oral squamous cell carcinoma HSC-2 cells was investigated to determine the pathogenic potential of SLS-producing β-hemolytic S. anginosus subsp. anginosus. This study revealed that the Ca2+ influx and the expression of immediate early genes (IEGs) encoding transcription factors such as early growth responses (EGRs) and activator protein-1 (AP-1) were greatly increased in HSC-2 cells incubated with the culture supernatant of SLS-producing β-hemolytic S. anginosus subsp. anginosus. Moreover, this SLS-dependent increase in expression was significantly suppressed by Ca2+ chelation, except for jun. These results suggest that SLS caused Ca2+ influx into the cells following greatly enhanced expression of IEG-encoding transcription factors. The results of this study may help in understanding the pathogenicity of SLS-producing AGS.

Abstract
OBJECTIVE We aimed to examine the factors contributing to radiation exposure exceeding the DRL of the transnasal ileus tube placement in this post hoc analysis from the cohort of the REX-GI study. METHODS Patients with transnasal ileus tubes were enrolled in the rex-gi study from may 2019 to december 2020. We investigated the endoscope insertion time (min), procedure time (min), tube insertion length (cm), fluoroscopy time (FT: min), air kerma at the patient entrance reference point (Ka.r: mGy), and air kerma-area product (PKA: Gycm2). The third quartile value of the PKA value was calculated as the diagnostic reference level (DRL) value. We explored the factors associated with radiation exposure exceeding the DRL. RESULTS In the REX-GI study, 496 patients who underwent transnasal ileus tube placement were enrolled. The median age of the patients was 71 years. The median endoscopy insertion time, procedure time, and tube insertion length were 6 min, 20 min, and 170 cm, respectively. The third quartile/median FT, Ka.r, and PKA were 18/11.9 min, 99.2/54.4 mGy, and 46.9/28 Gycm2, respectively. The third quartile value of PKA (47 Gycm2) was set as the DRL value. There were differences in distribution by the hospital. Compared with procedures under the DRL, the FT (19 vs 10 min), procedure time (25 vs 18 min), and tube insertion length (185 vs 165 cm) were significantly longer for procedures above the DRL. CONCLUSION We report the DRL for transnasal ileus tube placement in Japan. A longer procedure time and tube insertion length may be associated with DRL exceedance. ADVANCES IN KNOWLEDGE Transnasal ileus tube placement under fluoroscopy guidance is a standard clinical procedure for bowel obstruction. However, the appropriate radiation dose level has not yet been established.We report the (DRL) for transnasal ileus tube placement in Japan. A longer procedure time and tube insertion length may be associated with DRL exceedance.

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
BACKGROUND AND AIM Cold snare polypectomy is commonly performed to remove small colorectal polyps. Accidental resection of carcinomas during this procedure has been reported. Herein, we aimed to clarify the clinicopathological features and clinical course of colorectal carcinomas resected by cold snare polypectomy. METHODS This multicenter retrospective cohort study was conducted at 10 Japanese healthcare centers. Of the colorectal lesions resected by cold snare polypectomy between April 2016 and March 2020, lesions pathologically diagnosed as carcinoma were reviewed. Centralized histology (based on the Vienna classification) and endoscopic reviews were performed. The study endpoints were endoscopic features and clinical outcomes of cold snare polypectomy-resected colorectal carcinomas (Vienna category ≥4.2). RESULTS We reviewed 74 of the 70 693 lesions resected by cold snare polypectomy. After a central pathological review, 68 lesions were diagnosed as carcinomas. The Japan Narrow-band imaging Expert Team (JNET) classification type 2B, lesion size ≥6 mm, and multinodular morphology were the significant endoscopic predictors of carcinoma resected by cold snare polypectomy. No adverse events related to the procedure occurred. Sixty-three lesions were diagnosed as carcinomas within the mucosal layer, and 34 were curative resections. Of the five carcinoma lesions with submucosal invasion, additional surgery revealed remnant cancer tissues in one lesion. No local or metastatic recurrence was observed during follow-up. CONCLUSIONS Although most of the carcinomas resected by cold snare polypectomy were within the mucosal layer, few lesions invading the submucosa were identified. Careful pre-procedural endoscopic evaluation, especially focusing on the JNET classification and multinodular morphology, is recommended.

Abstract
AIM This study examined the relationship between continuity of social participation and progression of frailty among community-dwelling older adults, by baseline frailty level. METHODS This study was part of a 3-year community-based cohort study among adults aged ≥65 years, living independently in a rural municipality in Japan. Mail surveys were carried out in 2016, 2018 and 2019. This study involved 2799 participants who responded to the question about social participation in every survey. Frailty was evaluated by Kihon Checklist total scores. Social participation was categorized into consistent non-participation, interrupted recent non-participation, interrupted recent participation and consistent participation. We assessed the relationship between social participation and change in frailty scores using general linear regression analysis, stratifying the participants into groups by their frailty level at baseline. RESULTS There was a smaller frailty score increase in the robust (β -0.61, 95% CI -0.99 to -0.22) and prefrail groups (β -0.73, 95% CI -1.18 to -0.27) for consistent participation than consistent non-participation. Interrupted recent participation showed significant suppression in the prefrail group (β -0.96, 95% CI -1.60 to -0.32). Social participation had no clear effect on progression in the frail group. CONCLUSIONS Consistent social participation might reduce the progression of frailty in robust and prefrail people. Inconsistent participation might also help to reduce progression in prefrail older adults. It is important for prefrail older adults to return to their social activities and continue to engage as long as possible, even if their participation was intermittent in the past.

Abstract
BACKGROUND Although the combination of conventional endoscopy (CE) and endoscopic ultrasonography (EUS) is useful for predicting the depth of early gastric cancer (EGC), the diagnostic value of EUS for submucosal (SM) invasive cancer has not been fully investigated. METHODS We conducted a multicenter prospective study from May 2017 to January 2021 to evaluate the validity of a diagnostic strategy combining CE and EUS and to clarify the additional value of EUS for EGC suspected of SM invasion. In each case, the diagnosis was first made using CE, followed by EUS, and finally confirmed using a combination algorithm. RESULTS A total of 180 patients with EGC were enrolled from 10 institutions, of which 175 were analyzed. The histopathological depths were M, SM1, SM2, and ≥ MP in 72, 16, 64, and 23 lesions, respectively. Treatment included 92 endoscopic submucosal dissection cases and 83 surgical cases. The overall diagnostic accuracy classified by M-SM1 or SM2-MP was 58.3% for CE, 75.7% for EUS, and 78.9% for the combination of CE and EUS; the latter two were significantly higher than that of CE alone (P < 0.001). The CE, EUS, and combination accuracy rates in 108 differentiated-type lesions were 51.9%, 77.4%, and 79.6%, respectively; the latter two were significantly higher than CE alone (P < 0.001). A significant additive effect of EUS was observed in CE-SM2 low-confidence lesions but not in CE-M-SM1 lesions or in CE-SM2 high-confidence lesions. Among the nine CE findings, irregular surface, submucosal tumor-like elevation, and non-extension signs were significant independent markers of pSM2-MP. Poorly delineated EUS lesions were misdiagnosed. CONCLUSIONS EUS provides additional value for differentiated-type and CE-SM2 low-confidence EGCs in diagnosing invasion depth.

Abstract
BACKGROUND AND AIM Sessile serrated lesions (SSLs) act as precursors to colorectal cancer, sometimes harbor carcinomas, and are sometimes incompletely resected. We aimed to evaluate local recurrence after endoscopic resection of SSL ≥10 mm. METHODS This prospective, single-arm, observational study was performed at eight Japanese tertiary institutions. Colorectal lesions ≥10 mm were resected endoscopically, and the pathological diagnosis was either an SSL or hyperplastic polyp (HP). Follow-up colonoscopy was performed 1 year later, and the local recurrence was evaluated by biopsy. RESULTS From October 2018 to September 2021, 104 cases with 123 lesions were registered. Among the pathologically diagnosed 105 SSLs and 18 HPs, 95 and 7 lesions were diagnosed as SSLs and HPs, respectively, by central pathological review. Among the 104 endoscopically diagnosed SSLs, 86 were diagnosed as SSLs, whereas among the 11 endoscopically diagnosed HPs, two were diagnosed as HPs by central pathological review (the rest were SSLs). Among the 95 patients with 113 lesions who underwent follow-up colonoscopy, resection scars were identified in 95 (84%) lesions. Three (3.1%; 95% confidence interval 0.6-8.7%) local recurrences were diagnosed pathologically among 98 pathologically diagnosed SSLs. Two (6%) local recurrences were diagnosed in patients with SSLs ≥20 mm. CONCLUSIONS The local recurrence rate after endoscopic resection of SSLs ≥10 mm was 3.1%. Careful follow-up is recommended after endoscopic resection of large SSLs. Endoscopically diagnosed HPs ≥10 mm were sometimes pathologically diagnosed as SSL and should be considered for resection.

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
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
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
Radiation therapy is a representative therapeutic approach for cancer treatment, wherein the development of efficient radiation sensitizers with low side effects is critical. In this study, a novel stealth radiation sensitizer based on Au-embedded molecularly imprinted polymer nanogels (Au MIP-NGs) was developed for low-dose X-ray radiation therapy. Surface plasmon resonance measurements reveal the good affinity and selectivity of the obtained Au MIP-NGs toward the target dysopsonic protein, human serum albumin. The protein recognition capability of the nanogels led to the formation of the albumin-rich protein corona in the plasma. The Au MIP-NGs acquire stealth capability in vivo through protein corona regulation using the intrinsic dysopsonic proteins. The injection of Au MIP-NGs improved the efficiency of the radiation therapy in mouse models of pancreatic cancer. The growth of the pancreatic tumor was inhibited even at low X-ray doses (2 Gy). The novel strategy reported in this study for the synthesis of stealth nanomaterials based on nanomaterial-protein interaction control shows significant potential for application even in other approaches for cancer treatment, diagnostics, and theranostics. This strategy paves a way for the development of a wide range of effective nanomedicines for cancer 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
OBJECTIVES To clarify the association between moderate-to-vigorous physical activity (MVPA) and/or sedentary behaviour (SB) and the incidence of functional disability (FD) in older adults. DESIGN Prospective cohort study. SETTING Local municipality of Tsuru, Yamanashi, Japan. We conducted a baseline survey in January 2016. Follow-up was commenced on 1 February 2016 and completed on 31 October 2018. PARTICIPANTS All individuals (6661 people) aged >65 years who were independently living in the community were eligible. METHODS AND OUTCOME MEASURES MVPA (min/week) and SB (min/day) were measured using self-administered questionnaires in 5311 independently living older adults who participated in this study. The follow-up period was 33 months, and the incidence of FD was objectively determined by experts. The participants were divided into three groups based on MVPA distribution (non-MVPA, 0 min; short-MVPA, 1-299 min and long-MVPA, ≥300 min/week) and into two groups based on the median value of SB (short-SB,<190 min; and long-SB, ≥190 min/day). The participants were also classified into six categories based on different combinations of MVPA and SB. Cox proportional hazards model was used to calculate the HR and 95% CI for FD development with MVPA, SB and a combination of these behaviours. RESULTS Among the included participants, 2415 were male and 2896 were female. The mean ages (SD) of the male and female participants were 74.5 (6.8) and 74.9 (6.9) years, respectively. The total number of participants with chronic conditions was 3489 (65.7%). Using the non-MVPA group as the reference, the multivariable-adjusted HR (95% CI) was 0.68 (0.54 to 0.84) in the short-MVPA group and 0.53 (0.41 to 0.69) in the long-MVPA group. Regarding SB, the short-SB group had an HR of 0.86 (0.71 to 1.03) compared with the long-SB group. The combined behaviour showed the lowest HR in the long-MVPA and short-SB group 0.49 (0.34 to 0.72) and the long-MVPA and long-SB group 0.49 (0.34 to 0.68), respectively. CONCLUSIONS Long-MVPA had a robust association with FD development, whereas short-SB had a modest association. Moreover, a combination of these behaviours had a stronger association than individual behaviours. If the identified associations are assumed to be causal in nature, these findings suggest that encouraging older adults to engage in MVPA and reduce SB in their daily lives could be effective to prevent or delay FD development.

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
OBJECTIVES Data on the long-term outcomes of endoscopic submucosal dissection (ESD) performed in elderly patients with early colorectal cancer (CRC) are limited. We analyzed the prognosis of elderly CRC patients, not only from the viewpoint of treatment curability but also from the patients' baseline physical condition assessed by several indexes. METHODS A retrospective analysis of 729 patients aged ≥75 years who underwent ESD for Tis/T1 CRC in 16 institutions was conducted. The patients were classified into three groups based on curability: curative ESD (Group A, n = 582), non-curative ESD with additional surgery (Group B, n = 60), and non-curative ESD without additional surgery (Group C, n = 87). Overall survival (OS) was compared among the groups, and factors associated with reduced OS were investigated. RESULTS The median follow-up periods in Groups A, B, and C were 41, 49, and 46 months, respectively (P = 0.62), during which 92 patients died. Two patients (0.3%) in Group A, none (0%) in Group B, and three (3.4%) in Group C died of CRC. Three-year OS rates in Groups A, B, and C were 93.9%, 96.1%, and 90.1%, respectively, without a significant difference (P = 0.07). Multivariate analysis indicated low (<96.3) geriatric nutritional risk index (GNRI) as the sole independent predictor for reduced OS (hazard ratio 3.37; 95% confidence interval 2.18-5.22; P < 0.0001). CONCLUSIONS Low GNRI, but not the curability attained by ESD, was independently associated with reduced OS in patients with early CRC aged ≥75 years.

Abstract
BACKGROUND Diagnostic reference levels (DRLs) are required to optimize medical exposure. However, data on DRLs for interventional fluoroscopic procedures are lacking, especially in gastroenterology. This study aimed to prospectively collect currently used radiation doses and help establish national DRLs for fluoroscopy-guided gastrointestinal procedures in Japan. METHODS This multicentre, prospective, observational study collected actual radiation dose data from endoscopic retrograde cholangiopancreatography (ERCP), interventional endoscopic ultrasound (EUS), balloon-assisted enteroscopy (BAE), enteral metallic stent placement, and enteral tube placement from May 2019 to December 2020. The study outcomes were fluoroscopy time (FT: min), air kerma at the patient entrance reference point (Ka,r: mGy), air kerma area product (PKA: Gycm2), and radiation dose rate (RDR: mGy/min). Additionally, the basic settings of fluoroscopy equipment and the factors related to each procedure were investigated. This study was registered in the UMIN Clinical Trial Registry (UMIN 000036525). FINDINGS Overall, 12959 fluoroscopy-guided gastrointestinal procedures were included from 23 hospitals in Japan. For 11162 ERCPs, the median/third quartile values of Ka,r (mGy), PKA (Gycm2), and FT (min) were 69/145 mGy, 16/32 Gycm2, and 11/20 min, respectively. Similarly, these values were 106/219 mGy, 23/41 Gycm2 and 17/27 min for 374 interventional EUSs; 53/104 mGy, 16/32 Gycm2 and 10/15 min for 523 metallic stents; 56/104 mGy, 28/47 Gycm2, and 12/18 min for 599 tube placements; and 35/81 mGy, 16/43 Gycm2 and 7/15 min for 301 BAEs, respectively. For the overall radiation dose rate, the median/third quartile values of RDR were 5.9/9.4 (mGy/min). The RDR values at each institution varied widely. INTERPRETATION This study reports the current radiation doses of fluoroscopy-guided gastrointestinal procedures expressed as DRL quantities. This will serve as a valuable reference for national DRL values. FUNDING This work was supported by a clinical research grant from the Japanese Society of Gastroenterology.

Abstract
BACKGROUND For the early diagnosis of malignant biliary stricture due to biliary-pancreatic carcinoma, conventional biliary brush cytology with endoscopic retrograde cholangiopancreatography (ERCP; the conventional method) is not sensitive enough. METHODS Two hundred nine patients with biliary stricture who were admitted between September 2015 and June 2020 were enrolled in this study. Biliary brush cytology was performed on all patients. Samples were diagnosed independently by an expert pathologist and medical doctor with conventional cytology and photodynamic diagnosis (PDD) with 5-aminolevulinic acid. RESULTS The definitive diagnoses were 49 benign and 160 malignant diseases. The conventional method had a sensitivity of 77.5% (124/160) and specificity of 100% (49/49). The PDD method had a sensitivity of 77.5% (124/160) and specificity of 67.3% (33/49). The conventional method identified 36 malignant diseases as false negatives, while the PDD method enabled successful diagnoses of malignant diseases in 19 of these 36 patients. When PDD was combined with the conventional method, the sensitivity significantly increased to 89.4% (143/160, P=0.006), and for biliary tract diseases only, the sensitivity increased to 95.6% (88/92, P=0.001). CONCLUSIONS Malignant biliary stricture can be diagnosed effectively and safely with the in vitro PDD method. The sensitivity could be further increased by combining PDD with the conventional method.

Abstract
Eosinophilic gastroenteritis is a fairly uncommon condition. It has been suggested that allergic reactions may have played a role in the development of this illness. The case of a 66-year-old woman who had a total hysterectomy due to a right ovarian tumor is described here. At this operation, a sodium hyaluronate carboxymethylcellulose bioresorbable membrane (Seprafilm®) was used. She was admitted to our hospital 47 days after the operation with abdominal pain. Laboratory data indicated elevated WBC (29450/μl) and eosinophilia (69.2%), and CT scan showed thickening of intestinal wall and ascites around there. Ascites cytology showed a significant increase of eosinophils (94.0%). She began taking oral steroids after being diagnosed with eosinophilic gastroenteritis, and her symptoms improved quickly. Despite the fact that Seprafilm® was thought to be a reliable and safe tool, it was suggested that a foreign body reaction to Seprafilm® could lead to eosinophilic gastroenteritis.

Abstract
Orally administered ketoconazole may rarely induce liver injury and adrenal insufficiency. A metabolite formed by arylacetamide deacetylase (AADAC)-mediated hydrolysis has been observed in cellulo studies, and it is relevant to ketoconazole-induced cytotoxicity. This study tried to examine the significance of AADAC in ketoconazole-induced toxicity in vivo using Aadac knockout mice. Oral administration of 150 mg/kg ketoconazole resulted in the area under the plasma concentration-time curve values of ketoconazole and N-deacetylketoconazole, a hydrolyzed metabolite of ketoconazole, in Aadac knockout mice being significantly higher and lower than those in wild-type mice, respectively. With the administration of ketoconazole (300 mg/kg/day) for 7 days, Aadac knockout mice showed higher mortality (100%) than wild-type mice (42.9%), and they also showed significantly higher plasma alanine transaminase and lower corticosterone levels, thus representing liver injury and steroidogenesis inhibition, respectively. It was suggested that a higher plasma ketoconazole concentration likely accounts for the inhibition of the synthesis of corticosterone, which has anti-inflammatory effects, in the adrenal gland in Aadac KO mice. In Aadac knockout mice, hepatic mRNA levels of immune- and inflammation-related factors were increased by the administration of 300 mg/kg ketoconazole, and the increase was restored by the replenishment of corticosterone (40 mg/kg, s.c.) along with recoveries of plasma alanine transaminase levels. In conclusion, Aadac defects exacerbate ketoconazole-induced liver injury by inhibiting glucocorticoid synthesis and enhancing the inflammatory response. This in vivo study revealed that the hydrolysis of ketoconazole by AADAC can mitigate ketoconazole-induced toxicities.

Abstract
We have reported that the plasma zinc concentration gradually decreases with the progression of fibrosis and is related to hepatocellular carcinoma (HCC) development. The aim of this study was to examine the impact of the zinc concentration on HCC development (study 1) and the relationship between zinc intake and HCC development (study 2) in patients with hepatitis C virus (HCV) eradicated by direct‐acting antivirals (DAAs). A total of 599 sustained virological response (SVR) patients treated with DAAs without a history of HCC were retrospectively analyzed in this study. Eighty patients received supplemental zinc (Zn treatment group), and 519 patients did not receive zinc (no Zn treatment group). In study 1, the cumulative incidence rate of HCC was compared between the Zn treatment group and the no Zn treatment group. In study 2, the risk factors for HCC development were examined in the no Zn treatment group. In study 1, in the Zn treatment group, HCC did not develop during follow‐up, and the cumulative risk of HCC was significantly lower in the Zn treatment group than in the no Zn treatment group (P = 0.048). In study 2, the 1‐year and 3‐year cumulative incidence rates of HCC were 1.8% and 5.6%, respectively. The risk factors for HCC identified by multivariate analysis were male sex, cirrhosis, low platelet count before treatment, and low serum zinc concentration 12 weeks after the end of DAA therapy. Conclusion: The Zn concentration is related to HCC development in patients with HCV eradicated by DAA therapy. Oral zinc supplementation is recommended as a means of suppressing HCC development in patients who have achieved SVR.

Abstract
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.
