Purpose: This study investigated whether the oral vasopressin V 2 receptor antagonist tolvaptan has beneficial effects on mortality in real-world congestive heart failure (CHF) patients with hypoperfusion (i.e. the wet-cold pattern), from the viewpoint of cardiorenal syndrome., Methods: Data on 5511 consecutive CHF patients were extracted from the Tokyo CCU Network data registry. Congestion and hypoperfusion were defined by Nohria-Stevenson clinical profiles at the time of hospitalization. Propensity scores for tolvaptan use were calculated for each patient and used to assemble two matched cohorts of patients receiving tolvaptan or not in the CHF with and without hypoperfusion groups., Results: Of the entire study cohort, 1073 patients (19%) had CHF with hypoperfusion (i.e. the wet-cold pattern). In-hospital mortality was significantly higher for CHF patients with than without hypoperfusion (log-rank, P < 0.001). The rate of tolvaptan use did not differ significantly between CHF patients with and without hypoperfusion (15% vs. 14%, respectively; P = 0.7848). In the propensity-matched CHF with hypoperfusion cohort, there was a significant association between the use of tolvaptan and a reduction in in-hospital mortality (log-rank, P = 0.0052). Conversely, in the matched CHF without hypoperfusion cohort, tolvaptan use was not associated with in-hospital mortality (log-rank, P = 0.4417)., Conclusion: There was a significant association between the use of tolvaptan and a reduction in in-hospital mortality in CHF patients with, but not without, hypoperfusion. These findings hint at possible individualized therapies for patients with CHF., (© 2024. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Introduction: In recent years, most molecular target drugs have been administered orally, as prescribed at ambulatory services in hospitals and at patients' homes. Telephone follow-up is increasingly being used in clinical practice for patients needing additional support post-discharge and for the prevention of hospital readmissions. The purpose of this study was to clarify the clinical benefits of telephone follow-up while administering oral anticancer drugs., Methods: This was a single-center, observational, retrospective study. We evaluated hepatocellular carcinoma patients who received sorafenib or lenvatinib between March 2010 and February 2018. The primary endpoint was the incidence of adverse events., Results: From the total of 130 patients, 83 patients received telephone follow-up and 47 did not. The incidence of hand-foot skin reactions significantly reduced in patients with telephone follow-up (odds ratio (OR) 3.69, 95% confidence interval (CI) 1.16-11.8, p  = 0.020). The median durations (ranges) of adherence to oral chemotherapy were 259 days (15-1730) for the telephone follow-up group and 121 days (14-1105) for the no-telephone follow-up group ( p  < 0.001). Moreover, the disease control rate was significantly higher in the telephone follow-up group (OR 2.52, 95% CI 1.15-5.53, p  = 0.020)., Conclusions: Remote interventions, such as telephone follow-up, are useful means of managing adverse events in patients receiving oral anticancer drugs and can lead to improved treatment results., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Hepatocellular carcinoma (HCC) hemorrhaging/rupture is a rare adverse effect of lenvatinib, and only limited pathological examinations have been reported. This report presents the case of a 69-year-old man who suffered from cardiac arrest and died 7 days after starting lenvatinib treatment for HCC, with an autopsy subsequently performed. Crack and coagulated blood were observed in the largest tumor. Pathologically, the hemorrhaging area was scattered in nearly all of the HCC lesions, regardless of tumor differentiation. This pathological feature is unusual in normal HCC. Thus, it is believed to have been the effect of lenvatinib.

Background and Aim: Metachronous gastric cancer (GC) frequently occurs in patients who have undergone endoscopic resection (ER) for GC. We evaluated the risk for development of metachronous GC following ER for GC based on genetic polymorphisms for alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2), as well as alcohol consumption and smoking habits., Methods: We studied 77 patients who underwent ER for GC (median follow-up of 84 months). Genotyping of ADH1B/ALDH2 was performed using saliva sampling. Histories of alcohol consumption and smoking before and after ER and Helicobacter pylori eradication were documented., Results: Multivariate analyses revealed that homozygous slow-metabolizing ADH1B (hazard ratio [HR] = 2.38, P  < 0.13), heavy smoking (HR = 2.36, P  < 0.09), and cigarette smoking after ER (HR = 2.47, P  < 0.10) were not independently associated with the risk of secondary GC development. We analyzed the cessation status of the 38 patients who were classified as heavy smokers before ER based on their smoking habits after the ER and divided them into a cessation group ( n  = 27, non-smokers after ER) and a non-cessation group ( n  = 11). Cumulative incidence curves of secondary GC in the cessation and non-cessation groups revealed 5-year incidence rates of 19.0% and 45.0%, respectively ( P  = 0.02)., Conclusion: Continued cigarette smoking, at a high level, may be an important risk factor for the development of metachronous GC. Advice for smoking cessation should be given., (© 2023 The Authors. JGH Open published by Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

No prospective study on the efficacy of tenofovir alafenamide (TAF), a novel tenofovir prodrug, in preventing hepatitis B virus (HBV) reactivation has yet been reported. This multicenter prospective study enrolled HBV-carriers who received TAF to prevent HBV reactivation before antitumor or immunosuppressive therapy, and patients with resolved HBV infection who experienced HBV-reactivation and received TAF to prevent HBV reactivation-related hepatitis. The efficacy of prophylactic TAF in preventing HBV reactivation and HBV reactivation-related hepatitis was evaluated at 6 and 12 months after initiating TAF. Overall, 110 patients were administered TAF to prevent HBV reactivation or HBV reactivation-related hepatitis. Three patients died owing to primary disease, whereas one patient was transferred to another hospital within 6 months after initiating TAF. Seven patients died due to primary disease, and five patients were transferred to another hospital within 12 months after initiating TAF. Therefore, 106 and 94 (77 patients with HBV infection, 17 with previous-HBV infection) patients were evaluated at 6 and 12 months after initiating TAF, respectively. No patient experienced HBV reactivation, HBV reactivation-related hepatitis, or treatment discontinuation due to HBV reactivation or adverse events of TAF after 6 and 12 months. TAF could effectively prevent HBV reactivation and HBV reactivation-related hepatitis., (© 2023 Wiley Periodicals LLC.)

Progressive liver fibrosis after anti-HCV treatment is a risk factor for HCC. Angiopoietin-2 (Ang2) is associated with non-regression of liver fibrosis after direct-acting antiviral (DAA). This study evaluated the predictive value of serum Ang2 levels for HCC occurrence or recurrence after DAA administration. In this retrospective study, 310 HCV-infected patients treated with DAAs in 2014-2020 were screened and evaluated for HCC occurrence or recurrence every three-six months. Multivariate Cox regression analysis revealed that age ≥ 75 years (HR: 2.92, 95% CI: 1.34-6.33; p = 0.007) and baseline Ang2 level ≥ 464 pg/mL (HR: 2.75, 95% CI: 1.18-6.37; p = 0.019) were significantly associated with HCC occurrence after DAA therapy. A high or low risk of HCC after DAA therapy could be distinguished by the combination of age and baseline Ang2 level. The cumulative incidences of de-novo HCC at two and four years were 0.8% and 3.8% in the low-risk group and 22.6% and 27.1% in the high-risk group, respectively. Baseline Ang2 level ≥ 402 pg/mL was significantly associated with HCC recurrence in patients who achieved sustained virological response with DAAs (HR: 3.68). In conclusion, serum Ang2 levels can predict HCC occurrence and recurrence after successful HCV eradication by DAAs.

Introduction: Atezolizumab plus bevacizumab treatment is highly effective in patients with unresectable hepatocellular carcinoma (HCC). However, progressive disease (PD) occurs in approximately 20% of HCC patients treated with atezolizumab plus bevacizumab, resulting in a poor prognosis. Thus, the prediction and early detection of HCC is crucial., Methods: Patients with unresectable HCC treated with atezolizumab plus bevacizumab and had baseline preserved serum ( n = 68) were screened and classified according to their PD, 6 weeks after treatment initiation (early PD; n = 13). Of these, 4 patients each with and without early PD were selected for cytokine array and genetic analyses. The identified factors were validated in the validated cohort ( n = 60) and evaluated in patients treated with lenvatinib., Results: No significant differences were observed in the genetic alterations in circulating tumor DNA. Cytokine array data revealed that baseline MIG (CXCL9), ENA-78, and RANTES differed substantially between patients with and without early PD. Subsequent analysis in the validation cohort revealed that baseline CXCL9 was significantly lower in patients with early PD than that in patients without early PD, and the best cut-off value of serum CXCL9 to predict early PD was 333 pg/mL (sensitivity: 0.600, specificity: 0.923, AUC = 0.75). In patients with lower serum CXCL9 (<333 pg/mL), 35.3% (12/34) experienced early PD with atezolizumab plus bevacizumab, while progression-free survival (PFS) was significantly shorter relative to that in patients without (median PFS, 126 days vs. 227 days; HR: 2.41, 95% CI: 1.22-4.80, p = 0.0084). While patients with objective response to lenvatinib had significantly lower CXCL9 levels compared with those of patients without., Conclusion: Baseline low serum CXCL9 (<333 pg/mL) levels may predict early PD in patients with unresectable HCC treated with atezolizumab plus bevacizumab., Competing Interests: Professor Naoya Sakamoto received lecture fees from Bristol Myers Squibb and Janssen Pharmaceutical K.K.; grants and endowments from MSD, Pharmaceutical K.

Objective: Herein, we report a case of a patient with recurrent breast cancer who was diagnosed antemortem with pulmonary tumor thrombotic microangiopathy (PTTM) using wedge aspiration cytology of the pulmonary artery after breast cancer surgery., Case Summary: The patient was a 50-year-old woman who underwent mastectomy and axillary lymph node dissection for stage IIIA (T3N2M0) triple-negative left breast cancer. Postoperative follow-up was performed with radiotherapy and anticancer chemotherapy. Seventeen months after the surgery, the patient was hospitalized for right heart failure and diagnosed with pulmonary arterial hypertension. The patient was diagnosed with PTTM following the detection of malignant cells in the pulmonary artery using wedge aspiration cytology. Anti-pulmonary hypertension therapy was administered; however, the patient did not respond and died 26 days after admission. Autopsy revealed multiple microscopic tumor emboli in the pulmonary artery. In portions of the pulmonary artery without embolization, fibro-cellular intimal hyperplasia and stenosis were observed. Tumor embolism was expressed for CK7+/CK20-, consistent with the primary breast cancer., Discussion: Since the primary pathophysiology of PTTM entails narrowing due to fibro-cellular intimal hyperplasia rather than multiple tumor thrombi, the efficacy of chemotherapy combined with vasodilators is discussed.

The IMbrave150 trial demonstrated the high efficacy and safety of atezolizumab and bevacizumab for unresectable hepatocellular carcinoma (HCC). In this multicenter study, the efficacy of this combination and its effect on liver functional reserve were evaluated in patients not meeting the eligibility criteria of IMbrave150. Of 115 patients with unresectable HCC treated with atezolizumab and bevacizumab between October 2020 and January 2022, 72 did not meet the eligibility criteria of IMbrave150, most frequently due to a history of systemic therapy (60/72), platelet counts < 75 × 109/L (7/72), Child-Pugh B (9/72), and 2+ proteinuria (8/72). Atezolizumab and bevacizumab therapy was equally effective for patients who did or did not meet the eligibility criteria (PFS, 6.5 vs. 6.9 months, p = 0.765), consistent with subgroup analyses of histories of systemic therapy, platelet counts, Child-Pugh, and proteinuria. Baseline ALBI scores were worse in patients who did not meet the criteria than in those who did and significantly worsened after treatment initiation in patients not meeting the criteria (baseline vs. 12 weeks; 2.35 ± 0.43 vs. −2.18 ± 0.54; p = 0.007). Accordingly, atezolizumab plus bevacizumab was effective for patients not meeting the eligibility criteria of IMbrave150, although careful monitoring for changes in liver functional reserve is needed.

Recently, the efficacy was demonstrated of the Diamondback 360® Coronary Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc., St. Paul, MN, USA) for treating calcified coronary lesions in percutaneous coronary intervention (PCI). The safety and feasibility of OAS application through a 5-Fr guiding catheter (GC) which is less invasive and reduces access site complications were validated. This sequential, retrospective, observational study was conducted in a single center from September 2018 to May 2020. The primary endpoint was a successful PCI with the OAS. Secondary endpoints were major adverse complications related to PCI with the OAS, including coronary dissection, perforation, side branch loss, need for an unexpected cardiac assist device, access site complications, and major adverse cardiac and cerebrovascular events. 33 PCIs in 30 patients (mean age 72 ± 11 years; male, 83.3%) were surveyed. All PCIs were successfully completed with OAS application through a 5-Fr GC. Coronary perforation after the OAS procedure occurred in one case (3.0%). Severe coronary dissection occurred in three cases (9.1%), and procedural myocardial infarction in two cases (6.1%). Regarding PCIs performed with the 5-Fr GC, the OAS is a safe and feasible strategy for calcified plaque modification., (© 2021. Japanese Association of Cardiovascular Intervention and Therapeutics.)

The hydrostatic pressure dependent evolution of the electronic and magnetic structure of LaCo 5 and YCo 5 was investigated by means of x-ray emission spectroscopy, x-ray diffraction, and spin-polarized density functional theory (DFT) calculations. Using experimental lattice parameters the DFT correctly predicts the pressure of the magnetic transition in both compounds to be 26 GPa (La) and 22-23 GPa (Y). The transition was experimentally resolved in the changes of the electronic structure via the integrated absolute difference of the Co Kβ emission spectra. Comparison of theory and experiment confirm for the first time a common feature in both LaCo 5 and YCo 5 to be the source of the transition; the Fermi-level crossing of an up-spin polarized flat band driving the systems into a low spin configuration via a Lifshitz type transition of the Fermi surface. Another phase transition observed around 12 GPa in LaCo 5 was clarified to be caused by the change in the down-spin density of states at the Fermi level., (© 2022 IOP Publishing Ltd.)

Background: endoscopic retrograde cholangiopancreatography (ERCP) is a first-line procedure for biliary drainage in patients with acute cholangitis, and there are no studies focused on very urgent ERCP within several hours of hospital arrival. This study aimed to elucidate the use of very urgent ERCP for non-severe acute cholangitis., Methods: this retrospective observational study included patients with non-severe acute cholangitis who underwent ERCP between April 2011 and June 2020 in our institution. Patients were stratified into three groups based on time to ERCP after hospital arrival: very urgent (≤ 3 hours), urgent (3-24 hours) and elective (> 24 hours). The primary outcome was length of hospital stay (LOS)., Results: the study cohort included 291 patients, 168 males (57.7 %), with a median age of 76 (interquartile range, 70-83) years. In all, 47, 196 and 48 patients underwent very urgent, urgent and elective ERCP, respectively. Median LOS in the very urgent, urgent, and elective groups was 12, 14, and 15 days, respectively (Kaplan-Meier method). A shorter LOS was associated with earlier ERCP (log-rank trend test, p = 0.04). The rates of readmission within 30 days of discharge and of adverse events were not significantly different among the three groups. By multivariate analysis, very urgent ERCP was associated with a significantly earlier discharge than urgent and elective ERCP (HR, 0.71, p = 0.04 and HR, 0.47, p < 0.01, respectively). In addition, age ≥ 75 years, pancreatitis, albumin ≤ 2.8 g/dL and two or more ERCP procedures were associated with a significantly longer LOS (HRs < 1, p < 0.05)., Conclusions: very urgent ERCP for non-severe acute cholangitis was associated with early discharge.

Liver stiffness measurement (LSM) is a useful tool for assessing advanced liver fibrosis, an important risk factor for hepatocellular carcinoma (HCC) following hepatitis C (HCV) eradication. This study aimed to clarify the non-invasive factors associated with HCC following sustained virological response (SVR) and to identify the low-risk group. 567 patients without history of HCC who achieved SVR at 24 weeks (SVR24) after IFN-free treatment were retrospectively analyzed. The cumulative incidence of HCC and the risk factors were examined using pre-treatment and SVR24 data. The median observation period was 50.2 months. Thirty cases of HCC were observed, and the 4-year cumulative incidence of HCC was 5.9%. In multivariate analysis, significant pre-treatment factors were age ≥ 71 years (hazard ratio [HR]: 3.402) and LSM ≥ 9.2 kPa (HR: 6.328); SVR24 factors were age ≥ 71 years (HR: 2.689) and LSM ≥ 8.4 kPa (HR: 6.642). In cases with age < 71 years and LSM < 8.4 kPa at the time of SVR24, the 4-year cumulative incidence of HCC was as low as 1.1%. Both pre-treatment LSM (≥ 9.2 kPa) and SVR24 LSM (≥ 8.4 kPa) and age (≥ 71 years) are useful in predicting the risk of HCC after SVR with IFN-free treatment. Identification of low-risk individuals may improve the efficiency of follow-up., (© 2022. The Author(s).)

For long-term treatment of hepatitis B virus (HBV) infection, switching from tenofovir-disoproxil-fumarate (TDF) to tenofovir-alafenamide (TAF) may prevent renal dysfunction and bone loss. However, the precise effects of this switch on the blood lipid profile remain to be clarified. This is an important issue as TDF is known to have effects on both low- and high-density lipids. Therefore, our retrospective multi-center study aimed to evaluate the effects of switching from TDF to TAF on the lipid profile of patients with HBV infection. Samples were obtained prior to the switch from TDF to TAF and at 6-12 months after TAF initiation. In some cases, additional samples obtained pre- and post-TDF administration were available for analysis. Serum cholesterol levels, including oxidized-low-density lipoprotein (LDL) and non-high-density lipoprotein-cholesterol (HDL-c), and the rate of dyslipidemia, according to the NCEP-ATP III lipid risk classification, were analyzed. The data from 69 patients were analyzed, including 33 patients with pre- and post-TDF-initiation serum samples. Total cholesterol (T-chol), HDL-c, LDL-c, non-HDL-c, and oxidized LDL levels increased significantly after switching to TAF. With regard to sequential changes pre- to post-TAF, TDF was associated with significantly lower serum T-chol, HDL-c, and oxidized LDL-c levels, with T-chol, HDL-c, LDL-c, and oxidized LDL-c levels increasing significantly after the switch. The switch from TDF to TAF was also associated with an increase in the rate of dyslipidemia, from 33% to 39%, with an increase in the rate of severe dyslipidemia of 1.4% and 5.8%, based on T-chol and LDL-c levels. Of note, no cases of severe dyslipidemia were detected pre-TAF treatment. As oxidized LDL-c and non-HDL-c are strongly associated with atherosclerosis development, careful monitoring of lipid is needed after switching from TDF to TAF in this clinical population., Competing Interests: Professor Naoya Sakamoto received lecture fees from Bristol Myers Squibb and Pharmaceutical K.K, grants and endowments from MSD K.K and Chugai Pharmaceutical Co., Ltd., and a research grant from Gilead Sciences, Inc.

Objectives: The transradial approach (TRA) is recommended in coronary catheterization due to the lower rate of bleeding complications compared with the transfemoral approach. However, a disadvantage of TRA is difficulty in puncturing under palpation of the radial pulse alone without arterial visibility. To overcome this limitation, a vessel visualization device using near-infrared rays, Art View (Forte Grow Medical Company), was used in the puncture of the radial artery (RA)., Methods: Patients who underwent coronary angiography via the right RA with Art View were retrospectively surveyed. According to the quality of RA visibility, the performance of the Art View was rated as follows: 5 = excellent; 4 = good; 3 = fair; 2 = not good; and 1 = poor. The primary endpoint was the procedural success of TRA using the Art View device. The secondary endpoints were procedural time (from injection of local anesthesia to successful crossing of the guidewire attached to the sheath), number of RA punctures, and change of puncture method or approach site., Results: The Art View device was used in 38 patients (mean age, 71 ± 11 years). Puncturing of the visualized RA was successful in 30 patients (79.0%). Among successful cases, the mean procedural time was 142 ± 87 seconds. The success rates of each visualization evaluation were 100%, 100%, 84.6%, 33.3%, and 0% from grades 5 to 1, respectively (P<.01). The mean procedural times were 92 ± 18 seconds, 102 ± 58 seconds, 180 ± 75 seconds, 306 ± 80 seconds, and not available from grades 5 to 1, respectively (P<.01)., Conclusion: The Art View RA visualization device is useful for RA puncture.

Aim: A clinical trial (IMbrave150) indicated the efficacy and safety of atezolizumab plus bevacizumab for patients with unresectable hepatocellular carcinoma (HCC). In this study, we evaluated this therapeutic combination in a real-world setting, with a focus on patients who did not meet the IMbrave150 eligibility criteria., Methods: In this multicenter study, patients with unresectable HCC treated with atezolizumab plus bevacizumab between October 2020 and May 2021 were screened. In patients who did not meet IMbrave150 eligibility criteria, treatment responses and safety at 6 and 12 weeks were evaluated., Results: Atezolizumab plus bevacizumab was initiated in 64 patients, including 46 patients (71.9%) who did not meet IMbrave150 eligibility criteria. Most of these patients had a history of systemic therapy (44/46). The objective response rate and disease control rate observed using Response Evaluation Criteria in Solid Tumors 1.1 were 5.2% and 82.8% at 6 weeks and 10.0% and 84.0% at 12 weeks, respectively; these rates were similar between patients who met and did not meet the IMbrave150 criteria. Ten patients experienced progressive disease (PD) at 6 weeks. Portal vein tumor thrombosis was significantly associated with PD (p = 0.039); none of the 15 patients with hepatitis B virus-related HCC experienced PD (p = 0.050). The most common adverse events of grade 3 or higher were aspartate aminotransferase elevation (n = 8, 13.8%) and the safety profile was similar between patients who met and did not meet the IMbrave150 criteria., Conclusion: Most patients treated with atezolizumab plus bevacizumab did not meet the IMbrave150 criteria; however, the combination therapy showed good safety and efficacy at the early treatment phase., (© 2021 Japan Society of Hepatology.)

Background and Aim: The mechanism underlying carcinogenesis and the genomic features of superficial non-ampullary duodenal epithelial tumors (SNADETs) have not been elucidated in detail. In this study, we examined the genomic features of incipient SNADETs, such as small lesions resected via endoscopic treatment, using next-generation sequencing (NGS)., Methods: Twenty consecutive patients who underwent endoscopic treatment for SNADETs of less than 20 mm between January and December 2017 were enrolled. Targeted genomic sequencing was performed through NGS using a panel of 160 cancer-related genes. Furthermore, the alteration/mutation frequencies in SNADETs were examined., Results: The maximum size of the SNADETs examined in this study was 12 mm in diameter. Five SNADETs were classified as low-grade dysplasia (LGD) tumors, while 14 SNADETs were classified as high-grade dysplasia tumors. Only one carcinoma in situ was detected. NGS data for 16 samples were obtained. APC alterations were detected in 81% of samples (13/16). KRAS, BRAF, and TP53 alterations were detected in 25% (4/16), 18.8% (3/16), and 6.3% (1/16) of cases, respectively., Conclusion: We detected APC alterations in most small SNADETs resected via endoscopic treatment, from LGD to carcinoma samples. Even in SNADETs classified as small LGD exhibited KRAS and BRAF alterations., (© 2021 The Authors.

We examine electronic and crystal structures of iron-based superconductors Ln FeAsO 1- x H x ( Ln = La, Sm) under pressure by means of x-ray absorption spectroscopy (XAS), x-ray emission spectroscopy (XES), and x-ray diffraction. In LaFeAsO the pre-edge peak on high-resolution XAS at the Fe- K absorption edge gains in intensity on the application of pressure up to 5.7 GPa and it saturates in the higher pressure region. We found integrated-absolute difference values on XES for Ln = La, corresponding to a spin state, decline on the application of pressure, and then it is minimized when the T c approaches the maximum at around 5 GPa. In contrast, such the optimum value was not detected for Ln = Sm. We reveal that the superconductivity is closely related to the lower spin state for Ln = La unlike Sm case. We observed that As height from the Fe basal plane and As-Fe-As angle on the FeAs 4 tetrahedron for Ln = La deviate from the optimum values of the regular tetrahedron in superconducting (SC) phase, which has been widely accepted structural guide to SC thus far. In contrast, the structural parameters were held near the optimum values up to ∼15 GPa for Ln = Sm., (© 2021 IOP Publishing Ltd.)

A carrier doping by a hydrogen substitution in LaFeAsO 1- x H x is known to cause two superconducting (SC) domes with the magnetic order at both end sides of the doping. In contrast, SmFeAsO 1- x H x has a similar phase diagram but shows single SC dome. Here, we investigated the electronic and crystal structures for iron oxynitride Ln FeAsO 1- x H x ( Ln = La, Sm) with the range of x = 0-0.5 by using x-ray absorption spectroscopy, x-ray emission spectroscopy, and x-ray diffraction. For both compounds, we observed that the pre-edge peaks of x-ray absorption spectra near the Fe- K edge were reduced in intensity on doping. The character arises from the weaker As-Fe hybridization with the longer As-Fe distance in the higher doped region. We can reproduce the spectra near the Fe- K edge according to the Anderson impurity model with realistic valence structures using the local-density approximation (LDA) plus dynamical mean-field theory (DMFT). For Ln = Sm, the integrated-absolute difference (IAD) analysis from x-ray Fe- Kβ emission spectra increases significantly. This is attributed to the enhancement of magnetic moment of Fe 3 d electrons stemming from the localized picture in the higher doped region. A theoretical simulation implementing the self-consistent vertex-correction method reveals that the single dome superconducting phase for Ln = Sm arises from a better nesting condition in comparison with Ln = La., (© 2021 IOP Publishing Ltd.)

Background: Entecavir and tenofovir-disoproxil-fumarate are first-line nucleos(t)ide analogs (NA) for treatment of hepatitis B virus (HBV) infections; however, their long-term administration can impact extrahepatic organs. Herein, we sought to examine the effect of NA on lipid metabolism while also characterizing the associated mechanism., Methods: A retrospective study was performed on HBV patients administered entecavir or tenofovir-disoproxil-fumarate. Patient clinical information, as well as their preserved serum samples obtained at baseline and 6-12 months after treatment initiation, were analyzed. A 1:1 propensity score matching was applied to the assignment of tenofovir-disoproxil-fumarate or entecavir treatment. Changes in serum cholesterol, including oxidized-LDL, were analyzed. Subsequently, in vitro analysis elucidated the mechanism associated with the effect of NAs on lipid metabolism., Results: Administration of tenofovir-disoproxil-fumarate, not entecavir, to chronic HBV patients, decreased serum cholesterol levels, including non-HDL and oxidized-LDL, which are strongly associated with arteriosclerosis. In vitro analysis revealed that tenofovir-disoproxil-fumarate reduced supernatant cholesterol, and upregulated the scavenger receptor, CD36, in hepatocytes. Meanwhile, silencing of hepatic CD36 increased supernatant cholesterol and negated the cholesterol-reducing effect of tenofovir-disoproxil-fumarate in HepG2-cells. Reporter, microarray, and RT-PCR analyses further revealed that tenofovir-disoproxil-fumarate treatment activates PPAR-α-mediated signaling, and upregulates PPAR-α target genes, including CPT1 and CD36. Alternatively, silencing of PPAR-α reversed the effects of tenofovir-disoproxil-fumarate on CD36., Conclusions: Tenofovir-disoproxil-fumarate modulates lipid metabolism by upregulating hepatic CD36 via PPAR-α activation. Since dyslipidemia could be associated with arteriosclerosis and hepatocarcinogenesis, these discoveries provide novel insights into anti-HBV therapies, as well as the associated extrahepatic effects of NA.

There is no established hemostasis method or protocol for the transdistal radial approach. Therefore, this study aimed to determine whether "the PreludeSYNC DISTAL" radial compression device (PSD; Merit Medical Systems, Inc., South Jordan, UT) can effectively prevent distal radial artery (dRA) occlusion following catheterization procedures. This retrospective study analyzed patients who underwent hemostasis using the PSD from January 1, 2019, to March 31, 2019. The primary endpoint was occlusion or excessive stenosis of the radial artery (RA) 1 month after catheterization. Pulsatile blood flow and vessel diameters of the dRA and forearm RA (fRA) were measured using vascular ultrasound before and 1 month after catheterization to determine arterial damage. Secondary endpoints were achievement of hemostasis, bleeding, hematoma, aneurysm, neurological abnormality, and functional disturbance of the fingers or hand. Fifty patients (mean age, 70.9 ± 10.7 years; male, 72.0%) were enrolled in this study. Complete hemostasis was achieved in all cases. Total hemostasis time was 161 ± 45 min. No procedure-associated complications were noted. Pulsations of the dRA and fRA were maintained at 1 month. No functional disturbance or neurological abnormality was observed. Vessel diameters of the dRA and fRA were not significantly different before and 1 month after catheterization. No dissection, pseudoaneurysm, or occlusion/stenosis was observed on ultrasound. Distal radial access with a unique device and protocol effectively achieved hemostasis and prevented injury and occlusion of the dRA and fRA.

Non-Fermi-liquid (NFL), a significant deviation from Fermi-liquid theory, usually emerges near an order-disorder phase transition at absolute zero. Recently, a diverging susceptibility toward zero temperature was observed in a quasicrystal (QC). Since an electronic long-range ordering is normally absent in QCs, this anomalous behaviour should be a new type of NFL. Here we study high-resolution partial-fluorescence-yield x-ray absorption spectroscopy on Yb-based intermediate-valence icosahedral QCs and cubic approximant crystals (ACs), some of which are new materials, to unveil the mechanism of the NFL. We find that for both forms of QCs and ACs, there is a critical lattice parameter where Yb-valence and magnetism concomitantly exhibit singularities, suggesting a critical-valence-fluctuation-induced NFL. The present result provides an intriguing structure-property relationship of matter; size of a Tsai-type cluster (that is a common local structure to both forms) tunes the NFL whereas translational symmetry (that is present in ACs but absent in QCs) determines the nature of the NFL against the external/chemical pressure.

Calcified lesions still remain a technical challenge even in the treatment of infrainguinal artery disease. The aim of this retrospective, multicenter observational study was to investigate interventional outcomes of a high-speed rotational atherectomy device (Rotablator™) and to compare clinical outcomes in patients who underwent Rotablator and those who did not even after failed balloon angioplasty because of underlying calcified lesions. This study enrolled patients who underwent Rotablator (Rota group) and those who did not (Non-rota group) between January 2010 and 2014 December at 12 hospitals. A total of 67 limbs and 68 lesions in 65 patients were included (Rota group; 54 limbs and 55 lesions in 52 patients, Non-rota group; 13 limbs and 13 lesions in 13 patients). In the Rota group, a technical success rate was 94.5% with a complication rate of 1.8%, and all lesions underwent subsequent postdilatation following the adjunctive use of Rotablator, and approximately half of above-the-knee lesions underwent stent implantation. The Rota group had a significantly lower clinically driven reintervention rate at 12 months than the Non-rota group (26.5% vs. 58.3%, respectively, p = 0.046). In addition, Rota group showed a trend toward a higher amputation-free survival compared to the Non-rota group at 1 month (Rota; 98.0% vs. Non-rota; 84.6%, respectively, p = 0.10). Rotablator was used as an adjunctive device with a high technical success and a low complication rates, and Patients who underwent Rotablator yielded a significantly lower clinically driven reintervention rate at 12 months compared to those who did not even after failed balloon angioplasty.

Background: Many patients with emergent heart failure (HF) readmission have a delay between symptom onset and hospitalization. The present study aimed to characterize the interval between symptom onset and hospitalization in patients being readmitted for HF and to compare the clinical phenotypes of patients with delay before emergent readmission with those who presented to the hospital earlier., Methods: Data for a total of 2073 consecutive patients was collected from the Tokyo CCU Network database; the patients were divided into delayed (those who sought medical help > 2 days after symptom onset; n = 271) and early groups (remaining patients; n = 1802), and their clinical characteristics and mode of presentation were compared., Results: Age, sex, and laboratory findings including brain natriuretic peptide and serum creatinine levels were not significantly different between the two groups. Patients in the delayed group had greater chronic fluid retention and symptoms not associated with respiratory failure, whereas those in the early group were more likely to have acute respiratory distress, faster heart and respiration rates, and higher systolic blood pressure., Conclusions: More than one in ten patients with HF readmission delay seeking treatment > 2 days after symptom onset. Patients who delayed seeking treatment showed the phenotype of chronic fluid retention, whereas those who presented to the hospital earlier had the phenotype of acute respiratory failure., Competing Interests: Competing interestsDr. Kohsaka received an unrestricted research grant for the Department of Cardiology, Keio University School of Medicine, from Bayer Pharmaceutical Co., Ltd, and Daiichi Sankyo, Co., Ltd.

Aim: This study aimed to determine the efficacy and safety of lenvatinib for patients with unresectable hepatocellular carcinoma (HCC) who did not meet REFLECT eligibility criteria (phase 3 clinical trial)., Methods: In this multicenter retrospective study, patients with unresectable HCC treated with lenvatinib between 2018 and 2019 and had adequate clinical data were included. Objective response rate, progression-free-survival (PFS) and safety were evaluated according to meeting or not meeting the REFLECT eligibility criteria and according to the criteria of the REFLECT trial., Results: Of the 105 patients included, 61% (64 of 105) did not meet the REFLECT eligibility criteria. Safety and median PFS of lenvatinib were similar between the patients who did and those who did not meet the criteria. Among the patients who did not meet the criteria, 28, 27, 14, six, seven and five had a history of tyrosine kinase inhibitor (TKI) treatment, Child-Pugh score B, HCC in ≥50% of the liver, reduced platelet count, bile duct invasion and main portal vein invasion, respectively. The efficacy and safety of lenvatinib for patients with or without Child-Pugh-score B or HCC in ≥50% of the liver were similar. Although treatment outcome was not significantly different, patients with TKI treatment history tended to have longer median PFS, whereas those with main portal vein invasion tended to have shorter median PFS., Conclusion: Lenvatinib was effective for patients who did not meet the REFLECT inclusion criteria. However, the treatment outcome may vary according to several factors, such as a history of TKI treatment and tumor invasion., (© 2020 The Japan Society of Hepatology.)

Background: The absence of high quality, large-scale data that indicates definitive mortality benefits does not allow for firm conclusions on the role of intravenous vasodilators in acute heart failure. We aimed to investigate the associations between intravenous vasodilators and clinical outcomes in acute heart failure patients, with a specific focus on patient profiles and type of vasodilators., Methods: Data of 26,212 consecutive patients urgently hospitalised for a primary diagnosis of acute heart failure between 2009 and 2015 were extracted from a government-funded multicentre data registration system. Propensity scores were calculated with multiple imputations and 1:1 matching performed between patients with and without vasodilator use. The primary endpoint was inhospital mortality., Results: On direct comparison of the vasodilator and non-vasodilator groups after propensity score matching, there were no significant differences in the inhospital mortality rates (7.5% vs. 8.8%, respectively; P =0.098) or length of intensive/cardiovascular care unit stay and hospital stay between the two groups. However, there was a substantial difference in baseline systolic blood pressure by vasodilator type; favourable impacts of vasodilator use on inhospital mortality were observed among patients who had higher systolic blood pressures and those who had no atrial fibrillation on admission. Furthermore, when compared to nitrates, the use of carperitide (natriuretic peptide agent) was significantly associated with worse outcomes, especially in patients with intermediate systolic blood pressures., Conclusions: In acute heart failure patients, vasodilator use was not universally associated with improved inhospital outcomes; rather, its effect depended on individual clinical presentation: patients with higher systolic blood pressure and no atrial fibrillation seemed to benefit maximally from vasodilators., Trial Registration: UMIN-CTR identifier, UMIN000013128.

Objective: To elucidate the long-term outcomes of permanent endoscopic biliary stenting (EBS) and risk factors for recurrent biliary obstruction (RBO) in high-risk or elderly patients with common bile duct (CBD) stones., Methods: The electronic database of Hakodate Municipal Hospital was searched to identify elderly or high-risk patients with CBD stones who had undergone permanent EBS using a plastic stent without stone removal and were followed up between April 2011 and May 2019, with no further intervention until symptoms occurred., Results: We analyzed a total of 47 patients, of whom 19 (40.4%) were men, with a median age of 86 years (interquartile range 80-90 years). RBO and death without biliary disease occurred in 14 (29.8%) and 19 (40.4%) patients, respectively. The cumulative RBO rates at 20, 40, and 60 months were 22.1%, 31.8%, and 35.5%, respectively. The median time to RBO was 13.0 and 38.0 months in the group with CBD stone  ≥15 mm and 11-14 mm in diameter, respectively. The cumulative RBO incidence rate in the group with CBD stone ≤10 mm in diameter did not reach 50%. The cumulative RBO incidence rates were significantly different among the three groups based on the CBD stone diameter (competing risk analysis, P < 0.01). Multivariate analysis showed that an increase in CBD stone diameter predicted the increased risk of RBO (hazard ratio 1.26, P = 0.01)., Conclusions: Permanent EBS is a feasible option for high-risk patients with small CBD stones., (© 2020 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.)

Background and Aim: Hepatitis E virus (HEV) is mainly transmitted orally, either waterborne or zoonotic foodborne. Intestinal viruses such as rotavirus are known to induce type III interferon (IFN) in the gastrointestinal (GI) tract where type III IFN dominantly functions in comparison with type I IFN. Therefore, the aim of this study is to investigate the significance of type III IFN (IFN-λ3) in acute hepatitis E., Methods: IFN-λ3 and HEV RNA levels in the sera of patients with acute HEV infection and in the supernatant of HEV-inoculated cells were measured, using an in-house high-sensitivity method and reverse transcription-polymerase chain reaction, respectively., Results: High serum IFN-λ3 levels were found in the early phase of acute HEV infection, which normalized after resolution. Interestingly, serum IFN-λ3 levels correlated well with serum HEV RNA titers in the same sera, both of which showed the peak before the robust increase of transaminases. In vitro experiments demonstrated that HEV replicated well in the cells with little IFN-λ3 induction (Caco-2, A549) and recombinant IFN-λ3 inhibited HEV replication in a dose-dependent manner. In contrast, in HT-29 cells, a colon cancer cell line, HEV poorly replicated and induced IFN-λ3 in a titer-dependent manner., Conclusions: These clinical and experimental observations suggest that HEV induced IFN-λ3 as a host innate immune response, which may play a protective role against HEV., (Copyright © 2019 Elsevier Ltd.

Aim: Entecavir (ETV), tenofovir disoproxil fumarate (TDF), and tenofovir alafenamide (TAF) are first-line nucleos(t)ide analogues for hepatitis B virus (HBV)-infected patients. However, consecutive TDF treatment causes renal dysfunction, and the safety and efficacy of TAF have not been established in severe renal dysfunction patients, including hemodialysis patients. The efficacy and safety of ETV in these populations has not been clarified. The study aimed to clarify this., Methods: In this retrospective multicenter study, between 2006 and 2018, a total of 567 HBV-infected patients treated with ETV monotherapy were screened. Patients were included if >20 years old, treated with ETV monotherapy for >1 year, and had proper clinical information. The efficacy of ETV and changes in renal function were evaluated according to renal function., Results: A total of 273 patients were included: 9.2% (25/273), 1.8% (5/273), and 3.7% (10/273) had chronic kidney disease (CKD) stage G3, CKD stage G4/5, and were on hemodialysis, respectively. Overall, 84.2%, 94.0%, and 96.2% of patients experienced serum HBV-DNA disappearance at 1, 2, and 3 years, respectively, after treatment initiation. In patients with CKD stage G3-5, estimated glomerular filtration rate tended to restore with time, which was in contrast to patients without renal dysfunction. The rate of disappearance in serum HBV-DNA, alanine transaminase normalization, and virological breakthrough was similar between patients with or without renal dysfunction. ETV showed high efficacy for all 10 hemodialysis patients without virological breakthrough., Conclusions: Entecavir for HBV-infected patients with severe renal dysfunction, including hemodialysis patients, is highly effective and does not affect renal function., (© 2019 The Japan Society of Hepatology.)

Objectives: Heart failure with preserved ejection fraction (HFpEF) is now recognized as a geriatric syndrome with multifactorial pathophysiology and clinical heterogeneity rather than a solely left ventricular diastolic dysfunction. Because the pathophysiology of HFpEF is suggested to differ by age, this study compared the clinical characteristics and prognostic factors between HFpEF patients aged 65 to 84 years and those aged 85 years or older., Design: Retrospective cohort study., Setting: The Tokyo CCU Network including 73 hospitals in Tokyo, Japan., Participants: Individuals aged 65 years or older with HFpEF (N = 4305)., Measurements: Very old patients were defined as those aged 85 years or older. Potential risk factors for in-hospital mortality were selected by univariate analyses, and those with a P value <.10 were used in multivariate Cox regression analysis with forward selection (likelihood ratio) to identify significant factors., Results: Prevalence of hypertension was significantly higher in very old patients, whereas prevalence of coronary artery disease, diabetes mellitus, hyperlipidemia, and smoking was significantly higher in patients aged 65 to 84 years. In very old patients, low systolic blood pressure (hazard ratio [HR] = .988), high serum creatinine level (HR = 1.34), and coexisting chronic obstructive pulmonary disease (COPD; HR = 2.01) were identified as independent risk factors for in-hospital mortality. In contrast, low systolic blood pressure (HR = .987) and low body mass index (HR = .935) were identified as independent risk factors in patients aged 65 to 84 years., Conclusion: Significant differences were observed in the clinical characteristics and prognostic factors for in-hospital mortality between HFpEF patients aged 65 to 84 and those 85 years and older. Of note, coexisting COPD was associated with significantly lower survival rate only in patients aged 85 years and older, suggesting the prognostic impact of concomitant pulmonary disease in HFpEF may increase with age. These results have implications for future research and management of older HFpEF patients. J Am Geriatr Soc 00:1-6, 2019.

Background: Until recently, interferon-free anti-hepatitis C virus (HCV) therapy for genotype 2 (GT2) HCV-infected hemodialysis patients was an unfulfilled medical need. Recent clinical trials of glecaprevir and pibrentasvir (G/P) for hemodialysis patients showed high efficacy and safety; however, the number of GT2 HCV-infected patients, especially Asian patients, was limited and most of them were treated with a 12-week regimen. In this prospective multicenter study, we aimed to investigate the efficacy and safety of G/P in Japanese hemodialysis patients with GT2 HCV infection., Methods: Twenty-seven Japanese hemodialysis patients with GT2 HCV infection who were started on with 8- or 12-week G/P regimen between November 2017 and June 2018 were included and followed up for around 12 weeks after treatment completion., Results: Among the 27 included patients, 13 non-liver cirrhosis (LC) and direct-acting antivirals (DAAs)-naïve patients were treated with 8 weeks of G/P and 14 patients with LC (n = 13) or history of failure of DAAs (n = 1) were treated with a 12-week regimen. The overall sustained virological response at 12 weeks after treatment completion (SVR 12) was 96.3% (26/27). All patients with 8 weeks of treatment achieved SVR12. Two patients discontinued the therapy at 2 and 11 weeks after treatment initiation. The patient who discontinued at 2 weeks due to pruritus alone failed to respond to G/P. No patients experienced lethal adverse events during the therapy, and the most common adverse event was pruritus., Conclusions: An 8- or 12-week G/P regimen is highly effective and safe in GT2 HCV-infected hemodialysis patients.

Background and Aim: Lenvatinib has been recently approved as a first-line systematic therapy for patients with advanced hepatocellular carcinoma (HCC) based on the results of the phase 3 clinical trial REFLECT. This trial excluded patients with a history of systemic chemotherapy, bile duct invasion, and Child-Pugh grade B. We aimed to investigate the efficacy and safety of lenvatinib for these patients and in the real-world setting., Methods: Among patients who were administered lenvatinib for advanced HCC between April and October 2018 in Hokkaido University Hospital and related hospitals, we evaluated those who were followed for more than 2 months and whose treatment response was evaluated via dynamic computed tomography at baseline and 2 months after treatment initiation. Meanwhile, patients were excluded if they had decompensated liver cirrhosis, were followed up less than 2 months, or were not evaluated at 2 months. Patients were also stratified according to compliance with the REFLECT inclusion criteria for further analysis., Results: A total of 41 patients were included; more than 50% did not meet the REFLECT inclusion criteria. In total, 5 (12.2%), 20 (48.8%), 12 (29.3%), and 4 (9.3%) showed complete response, partial response, stable disease, and progressive disease, respectively. The objective response rate was 61.2%. The objective response rate and disease control rate were similar between patients who did and did not meet the REFLECT inclusion criteria. Moreover, the safety profile was also similar between the two patient groups., Conclusion: Lenvatinib showed high early response rate and tolerability in patients with advanced HCC. Favorable outcomes were similarly observed in patients who did not meet the REFLECT inclusion criteria., (© 2019 The Authors.

Objective: No agents have been proven to improve survival in heart failure with preserved ejection fraction (HFpEF), but the phenotypic diversity of HFpEF suggests it may be possible to identify specific HFpEF phenotypes that will benefit from certain treatments. This study compared the risk factors for and prognostic impacts of treatments on in-hospital mortality between HFpEF patients with (+) and without (-) high blood pressure (HBP)., Methods: Data on 2238 consecutive HFpEF patients were extracted from Tokyo CCU Network data registry and analysed. HFpEF was defined as an ejection fraction greater than or equal to 50%; HBP was defined as elevated systolic blood pressure (>140 mmHg) at admission. Potential risk factors for in-hospital mortality were selected by univariate analyses and those with P < 0.10 were used in multivariate Cox regression analysis with forward selection (likelihood ratio) to identify significant factors., Results: In-hospital mortality was significantly lower for HFpEF + HBP than HFpEF - HBP patients (log-rank, P < 0.001). Independent risk factors for in-hospital mortality in HFpEF + HBP patients were older age (hazard ratio 1.069) and in-hospital treatment without beta-blockers (hazard ratio 7.946), whereas older age (hazard ratio 1.035), higher C-reactive protein (hazard ratio 1.047), higher B-type natriuretic peptide (hazard ratio 1.000) and in-hospital treatment without diuretics (hazard ratio 4.201) were identified as independent risk factors in HFpEF - HBP patients., Conclusion: There were significant differences in prognostic factors, including beta-blocker and diuretic treatments, for in-hospital mortality between HFpEF patients with and without HBP. These findings suggest possible individualized therapies for patients with HFpEF.
