Varying impact of lenvatinib or sorafenib therapy on skeletal muscle loss in patients with hepatocellular carcinoma. Oncology 2024:000536501. [PMID: 38286117 DOI: 10.1159/000536501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 01/23/2024] [Indexed: 01/31/2024]
Abstract
BACKGROUND Lenvatinib and sorafenib are key therapeutic agents for hepatocellular carcinoma. However, there are no useful biomarkers for selecting molecular-targeted agents (MTAs). Skeletal muscle volume is associated with the clinical outcomes in these patients. We investigated the effects of lenvatinib and sorafenib on the skeletal muscles of patients with HCC. METHODS We evaluated the impact of skeletal muscle changes over a 3-month period for each MTA (n = 117; lenvatinib/sorafenib, 45/72). The skeletal muscle mass index (SMI) was measured at the third lumbar vertebra. Furthermore, we evaluated the direct effect of each MTA on primary human skeletal muscle cells by estimating muscle protein synthesis using western blot analysis. RESULTS The median change in SMI was -0.7% (p = 0.959) and -5.9% (p <0.001) for the lenvatinib and sorafenib groups, respectively. Sorafenib had a greater effect on skeletal muscle loss than lenvatinib (p < 0.001). Additionally, SMI significantly decreased in the sorafenib group regardless of initial skeletal muscle volume (p < 0.001), whereas no significant differences were observed in the lenvatinib group. Sorafenib therapy (odds ratio [OR], 2.98; p = 0.023) and non-muscle depletion (OR, 3.31; p = 0.009) were associated with a decreased SMI. In vitro analysis showed that sorafenib negatively affected muscle synthesis compared to lenvatinib. CONCLUSIONS Sorafenib may have a more negative effect on skeletal muscle than lenvatinib.

Abstract
PURPOSE/OBJECTIVE(S) To investigate the incidence of severe radiation-induced lymphopenia (SRL) and the survival in patients with stage Ⅲ non-small cell lung cancer treated with concurrent chemoradiotherapy with passive scattering proton beam (PSPT) or photon-based radiotherapy (XRT) including 3D-CRT and IMRT. MATERIALS/METHODS We conducted a retrospective cohort study including 355 patients who received definitive concurrent chemoradiotherapy with PSPT (n = 38) or XRT (n = 317) at our institution between January 2010 and December 2020. SRL during concurrent chemoradiotherapy was defined as absolute lymphocyte counts (ALCs) of <500 cells/mm3. Propensity score matching (PSM) analysis was performed to adjust for the patient characteristics between the PSPT and XRT groups. Propensity scores were calculated using age, sex, PS (0-1 vs. 2), primary tumor location (upper/middle vs. lower lobe), pathology (Adeno vs. Others), PTV volume, ALCs at pretreatment, year of treatment (before vs. after July 2018, when durvalumab approved in Japan), and platinum-based chemotherapy regimen (CDDP based vs. CBDCA based). After PSM, the incidence of SRL and the overall survival (OS) were analyzed. RESULTS The GTV and PTV volumes were significantly lower in the PSPT group than in the XRT group (median, 57 vs. 103 mm3; p < 0.05, 322 vs. 399 mm3; p < 0.05, respectively). ALCs at pretreatment were significantly lower in the PSPT group than in the XRT group (median, 1531 vs. 1718 cells/mm3; p < 0.05). SRL was observed in 275 patients (87%) in the XRT group and 27 patients (71%) in the PSPT group (p < 0.05). After PSM, PSPT significantly reduced the incidence of SRL compared to XRT (68.6 % vs. 88.6 %, p < 0.05), and the patients without SRL may have better 3-year OS than those with SRL (71.1 % vs. 55.3 %; p = 0.062). CONCLUSION Compared with XRT, PSPT significantly reduced the incidence of SRL, and the patients without SRL had a good prognosis.

Abstract
PURPOSE/OBJECTIVE(S) A nationwide multicenter cohort study on particle therapy was launched by the Japanese Society for Radiation Oncology (JASTRO) in Japan. We analyzed the outcome of proton beam therapy (PBT) for liver oligometastasis in breast cancers. MATERIALS/METHODS Cases in which PBT was performed at all Japanese proton therapy facilities between May 2016 and February 2019 were enrolled. The patients were selected based on the following criteria: the primary cancer was controlled, liver recurrence without extrahepatic tumors, and no more than three liver lesions. The treatment indication and strategy were discussed at cancer boards in each institution. The dose and fraction of PBT were determined by referring to the unified treatment policy established by JASTRO. We used the following protocol: 64 gray (Gy) (relative biological effectiveness [RBE])/8 fraction (fr) for the hepatic periphery area away from the GI tract, and 72.6 GyE/22 fr for the adjacent hilar region type. Regarding safety, the HCC irradiation protocols of 66 GyE/10 fr, 72.6-76 GyE/20-22 fr, and 74-76 GyE/37-38 fr could be used. The local control (LC), overall survival (OS), and progression free survival (PFS) rates were calculated using the Kaplan-Meier method. Factors possibly related to OS, such as tumor size, number of liver tumors, intervention of chemotherapy, and/or hormone therapy, were investigated. The cut-off values were estimated using the receiver operating characteristic curve and area under the curve. Univariate analysis was performed using the log-rank test. RESULTS Fourteen females, with a median age of 57 (range, 44-73) years and twenty-two lesions were included. Nine patients had one lesion, two patients had two lesions, and three patients had three lesions. PBT was selected because nine patients had underlying disease and five patients had general conditions (age, etc.). The median lesion size, fraction size, and biological effective dose using the linear-quadratic model with α/β = 10 Gy ((BED)10) were 44 (20-130) mm, 6.6 (2-8) (relative biological effectiveness [RBE])/fraction (fr), and 109.6 (52.7-115.2) Gy, respectively. The median follow-up period of breast cancers was 22.8 (4-54) months. The 1-, 2-, and 3-year LC rates of liver metastasis from breast cancers were 100% for all. The 1-, 2-, and 3-year OS rates were 85.7%, 62.5%, and 62.5%, respectively. The 1-, 2-, and 3-year PFS rates were 50.0%, 33.3%, and 16.7%, respectively, and median PFS time was 16 months. Tumor size, the number of liver tumors, and the intervention of chemotherapy and/or hormone therapy at any time were not significantly related to the OS. Only one patient did not complete PBT due to current disease progression. The other patients completed PBT without interruption. One patient had grade 3 radiation-induced dermatitis. CONCLUSION Based on the low incidence of adverse events and the high LC rate, PBT appears to be a feasible option for liver oligometastasis in breast cancer patients.

Abstract
PURPOSE/OBJECTIVE(S) Clinical practice is not always performed in accordance with guideline recommendations. Quality indicators (QIs) are valuable tools for evaluating the quality of healthcare systems. We sought to identify potential gaps between clinical practice and evidence using QIs previously developed using a modified Delphi method. MATERIALS/METHODS We used seven QIs (Table 1) to assess the quality of radiation therapy for bone (BoM) and brain metastases (BrM) at 29 centers; 13 (45%) were academic (12 university hospitals and 1 cancer center) and 16 (55%) were nonacademic hospitals. Compliance rate was calculated as the percentage of patients for whom recommended medical care was conducted. Random effects models were used to estimate pooled compliance rates. Mixed effects models with a Q test were used to compare compliance rates between academic and nonacademic centers. RESULTS The estimates of the compliance rates with 95% confidence intervals are presented in Table 1. For BoM-1, the compliance rate was higher in academic hospitals (100% [100-100%]) than in non-academic hospitals (96% [89-100%]) (P = 0.021). For BrM-3, the compliance rate was lower in academic hospitals (92% [81-99%]) than in nonacademic hospitals (100% [98-100%]) (P = 0.016). CONCLUSION A quality assessment based on these seven QIs is feasible. Overall, compliance rates were high; however, for BoM-3, the practice remains to be improved in some centers. Based on BoM-4 compliance rates, steroids are infrequently used concurrently with radiation therapy for malignant spinal cord compression. Extended fractionation for BoM was less frequently performed in academic than in nonacademic centers. The initiation of radiation therapy for brain metastases was more frequently delayed in academic than in nonacademic centers.

Methylated SEPT9 assay-based liquid biopsy as a biomarker in molecular targeted agent-treated hepatocellular carcinoma. Hepatol Int 2023; 17:1289-1299. [PMID: 37186217 DOI: 10.1007/s12072-023-10488-y] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 01/16/2023] [Indexed: 05/17/2023]
Abstract
BACKGROUND The development of molecular targeted agents (MTAs) has changed the treatment strategy for hepatocellular carcinoma (HCC). However, currently, there are no established predictive biomarkers for the treatment efficacy of MTAs. Previously, we developed a novel liquid biopsy test for HCC screening using sensitive methylated DNA testing of septin 9 gene (SEPT9). Here, we hypothesized that SEPT9 could be used as a biomarker for MTA treatment efficacy. METHODS We enrolled 157 patients receiving sorafenib or lenvatinib as a first-line therapy and allocated 85 and 72 patients to the training and validation cohorts, respectively. For the methylation assay, DNA was treated with methylation-sensitive restriction enzymes, followed by multiplex droplet digital PCR. Various clinical parameters were compared with clinical outcomes. RESULTS The multivariate analysis revealed Eastern Cooperative Oncology Group performance status (≥ 1; p = 0.048), alpha-fetoprotein (AFP) (≥ 400 ng/mL; p < 0.001), and methylated-septin-9 (m-SEPT9) (≥ 205 copies/mL; p = 0.018) as significant predictors of poor overall survival (OS) in the training cohort. m-SEPT9 was identified as a predictor of poor OS in the validation cohort. We developed a predictive score, called the MTA score, consisting of these three significant OS parameters (two points were added for AFP and one point for each of the other predictors). Patients with MTA scores ≥ 2 showed a significantly poor prognosis compared to those with MTA scores ≤ 1 in both the training and validation cohorts. CONCLUSIONS m-SEPT9 could be a potential predictive biomarker for survival in patients with HCC treated with MTAs.

Abstract
Despite the promising efficacy of atezolizumab plus bevacizumab (atezo/bev), some patients with unresectable hepatocellular carcinoma (HCC) experience disease progression. This retrospective study, which included 154 patients, aimed to evaluate predictors of treatment efficacy of atezo/bev for unresectable HCC. Factors associated with treatment response were examined, focusing on tumor markers. In the high-alpha-fetoprotein (AFP) group (baseline AFP ≥ 20 ng/mL), a decrease in AFP level > 30% was an independent predictor of objective response (odds ratio, 5.517; p = 0.0032). In the low-AFP group (baseline AFP < 20 ng/mL), baseline des-gamma-carboxy prothrombin (DCP) level < 40 mAU/mL was an independent predictor of objective response (odds ratio, 3.978; p = 0.0206). The independent predictors of early progressive disease were an increase in AFP level ≥ 30% at 3 weeks (odds ratio, 4.077; p = 0.0264) and the presence of extrahepatic spread (odds ratio, 3.682; p = 0.0337) in the high-AFP group and up-to-seven criteria, OUT (odds ratio, 15.756; p = 0.0257) in the low-AFP group. In atezo/bev therapy, focusing on early AFP changes, baseline DCP, and tumor burden of up-to-seven criteria are useful in predicting response to treatment.

Abstract
The purpose of this study is to investigate the effect of orthodontic anchor screws (OASs) inserted into the femur of growth-phase or mature rats using histological observation and bone structure analysis. The experimental animals are growth-phase (6-week-old) or mature (25-week-old) male Wistar rats. OAS was placed into the point one-third of the femoral length from the proximal end of the femur, and the response of the surrounding bone was observed and measured. The results showed at the OAS bone interface, in growth-phase rats, bone mineral density (BMD) was reduced and the running angle of collagen fiber bundles varied significantly. In mature rats, more osteoid was observed and biological apatite (BAp) crystals showed a different orientation. It was suggested that after the insertion of OASs, bone volume and quality are decreased, but after a sufficient healing period, a new bone micro/nano structure, different from the original structure, are reconstructed.

A combination of liver stiffness and international normalized ratio is an ideal prognostic predictor of portosystemic shunt occlusion in patients with portal hypertension. J Gastroenterol 2023; 58:246-256.

Abstract
BACKGROUND We previously reported liver stiffness (LS) as a prognostic predictor of portosystemic shunt (PSS) occlusion. This study aims to reinvestigate the predictive factors of the model for end-stage liver disease-sodium (MELD-Na) score amelioration following balloon-occluded retrograde transvenous obliteration (BRTO) and to evaluate the postoperative prognoses of patients with portal hypertension by using newly identified factors. METHODS Seventy-five patients who underwent BRTO between 2008 and 2021 were retrospectively enrolled. The MELD-Na scores were calculated preoperatively and one month postoperatively. We monitored long-term outcomes and analyzed postoperative survival. RESULTS At one month postoperatively, the MELD-Na score decreased in 46 (61.3%) patients. Univariate analyses revealed a significant association of the score amelioration with nine factors, including lower LS levels and a higher international normalized ratio (INR). A multivariate logistic regression analysis with receiver operating characteristic curve analyses identified preoperative LS levels and INR as significant independent predictors of the postoperative MELD-Na score amelioration, with optimal cutoffs of 28.1 kPa and 1.06, respectively. The combination of LS < 28.1 kPa and INR ≥ 1.06 showed a sensitivity and specificity of 84.8% and 75.9% for the prediction of the score amelioration, respectively. For the propensity score model, we matched 24 patients with similar age, sex, MELD-Na score, and concomitant hepatocellular carcinoma. Kaplan-Meier analysis determined significantly higher cumulative survival rates in patients with LS < 28.1 kPa and INR ≥ 1.06 than in other populations. CONCLUSIONS A combination of LS and INR can predict the MELD-Na score amelioration and prognosis improvement following PSS occlusion.

Abstract
AIM Primary hepatic angiosarcoma (PHA) is extremely rare, and its imaging findings are similar to those of other liver tumors including hepatocellular carcinoma (HCC). Here, we report a case of hepatitis C virus (HCV)-related HCC followed by PHA that showed remarkable clinical response to atezolizumab plus bevacizumab (Atezo/Bev) therapy. CASE PRESENTATION A 78-year-old man with recurrent HCC had a liver tumor with lymphadenopathy. Although considered as HCC recurrence, microscopic examination of the resected liver and lymph node showed PHA. Three months later, a solitary lung nodule was newly detected and subsequently resected. The pathological diagnosis was poorly differentiated HCC. Therefore, the patient was finally diagnosed with double cancer of PHA and HCC. Thereafter, he developed a new liver tumor with lymphadenopathy and received Atezo/Bev therapy. Liver tumor biopsy was carried out before the treatment. The pathological diagnosis was angiosarcoma. The patient showed a partial response after two courses of Atezo/Bev therapy. CONCLUSION To our best knowledge, this report is the first case to present HCV-related HCC followed by PHA and to show that Atezo/Bev therapy is beneficial for PHA.

Abstract
Recent advances in antiviral therapy have enabled control of the hepatitis virus; however, these do not completely eliminate the pathological condition of liver disease, and portal hypertension remains a clinical problem. We herein report a case of hepatitis B virus/hepatitis C virus (HBV/HCV)-induced decompensated liver cirrhosis for which total management consisting of interventional radiology and endoscopy, based on the evidence of our clinical studies, followed by antiviral therapy for co-infection with HBV and HCV was successful. This case clearly indicates the effective timing of total management, suggesting that it prolongs the vital prognosis in addition to improving the hepatic function.

Abstract
Social detachment due to coronavirus disease (COVID-19) has caused a decline in physical activity, leading to sarcopenia and frailty in older adults. This study aimed to compare muscle mass, strength, and function values in older women before and after the first wave of the COVID-19 pandemic (April-May 2020). Furthermore, changes in muscle measures across women who experienced different levels of impact on their social participation due to the COVID-19 pandemic were examined. Muscle mass (total, trunk, and appendicular muscle), grip strength, oral motor skills, social interactions (social network and participation), and social support were assessed in 46 Japanese community-dwelling older women (mean, 77.5 y; range 66-93 y) before and after the first wave of the COVID-19 pandemic. Trunk muscle mass significantly decreased after the first wave of the pandemic. When comparing changed values between the enhanced/maintained and reduced group during the pandemic, significant group difference was observed in trunk muscular mass, grip strength, and oral motor skills. Intriguingly, those who enhanced social participation had a positive change of grip strength values, showing that social participation might influence muscle function during the COVID-19 pandemic.

Abstract
AIM This study aimed to demonstrate the feasibility of identifying candidates of portopulmonary hypertension (PoPH) from general portal hypertension patients based on chest computed tomography (CT) results. METHODS One hundred and thirty patients with portal hypertension who had undergone interventional radiology therapies at our hospital between August 2011 and July 2021 were included, and preoperative clinical data were collected. Suspicious PoPH was defined as main pulmonary artery diameter (mPA-D) ≥ 29 mm or the ratio of mPA-D to ascending aorta diameter (mPA-D/aAo-D) ≥ 1.0, and probable PoPH as mPA-D ≥ 33 mm based on the chest CT. Prevalence of suspicious and probable PoPH was evaluated, and the differences in clinical characteristics of each population were compared. RESULTS Overall, 29 (22.3%) and 5 (3.8%) patients were categorized as suspicious and probable PoPH, respectively. Univariate analyses revealed that female sex, higher shortest diameter of inferior vena cava, presence of portosystemic shunts ≥ 5 mm, and lower blood urea nitrogen levels were significantly associated with suspicious PoPH (p < 0.05). Multivariate analyses identified all four factors as significantly independent determinants of suspicious PoPH (p < 0.05). In addition, among the population of suspicious PoPH, there were significant differences in seven parameters, including total bilirubin levels and spleen volume between patients with and without probable PoPH (p < 0.05). However, no significant independent indicators of probable PoPH were found. CONCLUSIONS CT-based measurements of mPA-D and mPA-D/aAo-D have the potential to screen patients with suspicious PoPH in clinical practice focused on portal hypertension.

Abstract
Abstract
Background and purpose
Arrhythmias such as atrial fibrillation (AF) is often associated with depression, with vague anxiety about symptom and the risk of serious complication such as stroke or heart failure. In the geriatric population, geriatric depression often occurs with an increase of physical illness and has substantial costly and quality of life implications for functionality and life satisfaction. However, few studies have investigated relationship between geriatric depression and Quality of Life (QoL), and arrhythmia symptoms (palpitation, dyspnea and chest discomfort).
Method
Between November 2019 and October 2020, elderly people (≥65 years) who participated in the AF awareness symposium were enrolled in this study. They were divided into 4 groups according to the presence or absence of chest symptom and AF, and were examined geriatric depression by Geriatric depression scale (GDS)-15 and Quality of Life (QoL) by the 12-item Short- Form Health Survey (SF-12) including physical and mental health status.
Results
Of the 1511 subjects, 1364 were analyzed after excluding 147 with missing values. Among them, 911 were in the non-AF group without symptom (Group A), 43 in the AF group without symptom (group B), 323 in the non-AF group with symptom (group C), and 87 in the AF group with symptom (group D).
Geriatric depression rates (defined as GDS-15 ≥10) were 2.7% in non-symptomatic group (2.7% in A [n=25] and 2.3% in B [n=1]) and 7.8% in symptomatic group (7.4% in C [n=24] and 9.2% in D [n=8]). (P<0.05) In multivariate regression analysis, an increased risk of geriatric depression was observed in groups C and D (group C: odds ratio [OR]=2.54, CI: 1.40, 4.61, P<0.01 and group D: OR=3.13 CI: 1.16, 7.57, P=0.02).
The mean values of physical and mental health status in SF-12 were 48.5 (±7.9) and 56.7 (±6.8) in A, 44.6 (±10.7) and 57.3 (±7.3) in B, 45.0 (±9.9) and 53.8 (±7.7) in C, and 43.4 (±10.8) and 54.8 (±8.6) in D, respectively. Physical health status in SF-12 was associated with group C (C vs A: estimate −2.95 [CI: −4.03, −1.87], p<0.01) and D (D vs A: estimate −2.93 [CI: −4.88, −0.97], p<0.01), other than heart failure, older age and female. Mental health status in SF-12 was associated with group C (C vs A: estimated −2.34 [CI: −3.72, −1.42], p<0.01), heart failure, hypertension, older age, female and group D (D vs A: estimate −1.63 [CI: −3.31, 0.05], p=0.06), but not statistically significant. Individuals with arrhythmia symptom (group C and D) had lower physical and mental health status than those without (group A and B) (P<0.05).
Conclusion
Older adults with arrhythmia symptoms were more likely to have geriatric depression and low QoL, especially those with symptomatic AF, with a geriatric depressive complication rate of 9.2%. Further studies are needed to investigate whether improving physical health status can improve QoL and geriatric depression.

Abstract
Abstract
Background
Atrial fibrillation (AF) is associated with increased risks of stroke and heart failure. AF risk prediction can facilitate the efficient deployment of diagnosis or interventions to prevent AF.
Purpose
We sought to assess the combination prediction value of Holter electrocardiogram (Holter ECG) and the CHARGE-AF score (Cohorts for Aging and Research in Genomic Epidemiology-AF) for the new-onset of AF in a single center study. We also investigated the association between clinical findings and the new-onset of cerebral cardiovascular events.
Methods
From January 2008 and May 2014, 1246 patients with aged≥20 undergoing Holter ECG for palpitations, dizziness, or syncope were recruited. Among them, 350 patients were enrolled in this study after exclusion of 1) AF history at the time of inspection or before, 2) post cardiac device implantation, 3) follow-up duration <1 year, and 4) no 12-lead ECG records within 6 months around Holter ECG.
Results
During the 5.9-year follow-up, 40 patients (11.4%) developed AF incidence. Multivariate cox regression analysis revealed that CHARGE-AF score (hazard ratio [HR]: 1.59, 95% confidence interval (95% CI): 1.13–2.26, P<0.01), BMI (HR: 0.91, 95% CI: 0.83–0.99, P=0.03), frequent supraventricular extrasystoles (SVEs) ≥1000 beats/day (HR: 4.87, 95% CI: 2.59–9.13, P<0.001) and first-degree AV block (HR: 3.52, 95% CI: 1.63–7.61, P<0.01) were significant independent predictors for newly AF. The area under the ROC curve (AUC) of the combination of the CHARGE-AF score and frequent SVEs (≥1000) was greater than the CHARGE-AF score alone (0.73, 95% CI: 0.64–0.82 vs 0.66, 95% CI: 0.56–0.75, respectively). On the ROC curve, the CHARGE-AF score of 12.9 was optimum cut-off value for newly AF. Patients with both the CHARGE-AF score≥12.9 and SVEs≥1000 developed AF at 129.0/1000 person-years, compared with those with the CHARGE-AF score<12.9 and SVEs≥1000 (48.9), the CHARGE-AF score≥12.9 and SVEs<1000 (40.0) and the CHARGE-AF score<12.9 and SVEs<1000 (7.4), respectively. In multivariate cox regression analysis, age, past history of congestive heart failure and myocardial infarction, and antihypertensive medication were significant predictors of cerebral cardiovascular events (n=43), all of which signifying the components of the CHARGE-AF score. The AUC of the combination of the CHARGE-AF score and frequent SVEs (≥1000) was not different from the CHARGE-AF score alone (0.73, 95% CI: 0.64–0.81 vs 0.73, 95% CI: 0.64–0.82, respectively).
Conclusion
CHARGE-AF score has higher predictive power of both the new incident AF and cerebral cardiovascular events. The combination of CHARGE-AF score and SVEs≥1000 beats/day in Holter ECG can demonstrate the additional effect of prediction ability for the new incident AF, but not for cerebral cardiovascular events.

Short-term Effects of Hepatic Arterial Buffer Responses Induced by Partial Splenic Embolization on the Hepatic Function of Patients with Cirrhosis According to the Child-Pugh Classification. Intern Med 2021; 60:1331-1342.

Abstract
Objective This study primarily aimed to investigate the short-term effects of partial splenic embolization (PSE) on the Child-Pugh score and identify predictive factors for changes in the score caused by PSE. The secondary aim was to analyze changes in various parameters at one month postoperatively using these identified factors. Methods Between September 2007 and December 2019, 118 patients with cirrhosis and hypersplenism underwent PSE at our hospital. Testing was conducted preoperatively and at one month after PSE. Results Overall, the Child-Pugh score was not significantly changed postoperatively. The Child-Pugh score before PSE was identified as the strongest independent predictor of ameliorated and deteriorated Child-Pugh scores after PSE. Higher pretreatment Child-Pugh scores were correlated with higher posttreatment amelioration rates of the score. A significant decrease in the portal vein diameter and a significant increase in the common hepatic artery diameter were evident at the same level postoperatively in 64 patients with Child-Pugh class A (group A) and in 54 patients with Child-Pugh class B or C (group B/C) preoperatively. According to Murray's Law, PSE resulted in decreased portal venous flow and increased hepatic arterial flow, suggesting a hepatic arterial buffer response (HABR) induced by the procedure. Despite equivalent splenic infarction rates and similar posttreatment changes in hepatic hemodynamics, PSE significantly increased the Child-Pugh score of group A; however, the procedure significantly decreased the score of group B/C. Conclusion Considering original portal venous-hepatic arterial hemodynamics, PSE is expected to produce HABR-mediated hepatic functional improvements in cirrhosis patients with Child-Pugh class B/C.

Abstract
Either the triggering of large earthquakes on a fault hosting aseismic slip or the triggering of slow slip events (SSE) by passing seismic waves involve seismological questions with important hazard implications. Just a few observations plausibly suggest that such interactions actually happen in nature. In this study we show that three recent devastating earthquakes in Mexico are likely related to SSEs, describing a cascade of events interacting with each other on a regional scale via quasi-static and/or dynamic perturbations across the states of Guerrero and Oaxaca. Such interaction seems to be conditioned by the transient memory of Earth materials subject to the "traumatic" stress produced by seismic waves of the great 2017 (Mw8.2) Tehuantepec earthquake, which strongly disturbed the SSE cycles over a 650 km long segment of the subduction plate interface. Our results imply that seismic hazard in large populated areas is a short-term evolving function of seismotectonic processes that are often observable.

Splenic non-infarction volume determines a clinically significant hepatic venous pressure gradient response to partial splenic embolization in patients with cirrhosis and hypersplenism. J Gastroenterol 2021; 56:382-394.

Abstract
BACKGROUND This study aimed to investigate changes in the hepatic venous pressure gradient (HVPG) by partial splenic embolization (PSE) and to identify the determinants of a clinically meaningful postoperative HVPG reduction. METHODS Sixty-eight patients with cirrhosis and hypersplenism who underwent PSE at our department between September 2007 and June 2020 were included. The HVPG was evaluated pre- and immediately post-PSE. The patients were divided into three groups according to their preprocedural HVPG: low-HVPG (< 10 mmHg, n = 22), intermediate-HVPG (10 mmHg ≤ HVPG < 16 mmHg, n = 33), and high-HVPG (≥ 16 mmHg, n = 13). RESULTS Overall, PSE significantly reduced HVPG from 12.2 ± 4.0 to 9.4 ± 3.6 mmHg (p < 0.01) with a relative decrease of 22.2 ± 20.4%. In addition, HVPG reductions were 19.4 ± 28.7%, 24.0 ± 15.9%, and 22.5 ± 13.3% in the low-, intermediate-, and high-HVPG groups, respectively, indicating no significant difference in HVPG reduction between the groups. An HVPG decrease of ≥ 20% from the baseline, defined in this study as a clinically significant HVPG response to PSE, was achieved in 55.9% of all patients. Multivariate logistic regression and receiver operating characteristic curve analyses identified splenic non-infarction volume as an independent determinant of a 20% decrease in HVPG (p < 0.05), with a cut-off of 139.2 cm3 (sensitivity, 76.3%; specificity, 60.0%; p < 0.05). CONCLUSIONS The splenic non-infarction volume, namely the residual functional spleen volume, independently determines a clinically significant HVPG response to PSE in patients with cirrhosis and hypersplenism.

Abstract
Abstract
Introduction
Patients with heart failure are reported to have activated platelets leading to thrombotic events. Consequently, immature giant platelets are produced, and platelet distribution width (PDW) and mean platelet volume (MPV) increase. These platelet indices are easily, reasonably, and safely available by routine blood test and recently have been proposed as potential markers of cardiac events. However, little is known about the usefulness of platelet indices in patients with congenital heart disease (CHD).
Purpose
To test whether the hypothesis that PDW and MPV correlate to the severity of heart failure and have prognostic value in both future heart failure-related admission and thrombosis formation in patients with CHD.
Methods
We performed a retrospective, single-centre study that included 400 patients with CHD (median age, 34 years [range: 12–76]; 49% males; 35% single ventricular morphology), who were admitted in our institute between April 2014 and June 2017. We reviewed patients' medical records to assess their clinical information including medical history, blood sample data, and echocardiologic parameters. At first, we assessed the correlation between platelet indices and patients' clinical parameters. Next, we compared platelet indices before and after treatment for heart failure. Finally, using logistic regression and Kaplan-Meier analyses, we assessed prognostic factors of future heart failure-related admission and thrombosis formation.
Results
In multivariate analysis, a significant correlation was found between PDW and logBNP (brain natriuretic peptide) (p<0.001), haemoglobin (p=0.01), D-dimer (p=0.019), Fontan operation (p<0.001) and male sex (p<0.001); as well as between MPV and logBNP (p<0.001), D-dimer (p<0.001) and Fontan operation (p=0.002). Throughout treatment of heart failure, significant reduction was found both in PDW (average value before treatment = 14.2, after treatment = 13.2, p=0.002) and MPV (before = 11.2, after = 10.8, p=0.004). In multivariate logistic regression analysis, predictors of future heart failure-related admissions were PDW (hazard ratio [HR]: 1.365; 95% confidence interval [CI]: 1.005–1.768), MPV (HR: 1.472; 95% CI: 1.055–2.052), age (HR: 1.063; 95% CI: 1.010–1.119), and SpO2 under 85% (HR: 5.089; 95% CI: 1.350–19.18). Using the same analysis, predictors of thrombotic formation were PDW (HR: 1.998; 95% CI: 1.461–2.630), MPV (HR: 1.792; 95% CI: 1.155–2.781), logBNP (HR: 1.196, 95% CI: 1.085–1.320), D-dimer (HR: 1.024; 95% CI: 1.007–1.042) and male sex (HR: 3.071; 95% CI: 1.079–8.737). In addition, during median follow-up of 28 months, the Kaplan-Meier analysis showed an improvement in both heart failure and thrombosis-free survival in the low PDW, as well as the low MPV group.
Conclusion
Platelet volume indices correlate to severity of heart failure and have prognostic value for both cardiac and thrombotic events in patients with congenital heart disease.

Abstract
This study describes a case of hepatitis C virus-related decompensated cirrhosis with portal-systemic liver failure and refractory encephalopathy. It was successfully managed with a combination of interventional radiology and pharmacotherapy, to improve hepatic function, including hyperammonemia and to control portal-splenic venous hemodynamics with hepatic venous pressure gradient (HVPG) monitoring. A man in his late 50s presented with a Child-Pugh score of 13, Model for End-Stage Liver Disease-sodium (MELD-Na) score of 19 and blood ammonia level of 185 μg/dL. He underwent balloon-occluded retrograde transvenous obliteration (BRTO) followed by partial splenic embolization (PSE) and non-selective beta-blocker (NSBB) administration. BRTO induced drastic changes in the portal-splenic venous hemodynamics, resulting in dramatically improved hepatic function and reduced hyperammonemia. However, the procedure resulted in increased HVPG from 13.6 mmHg at baseline to 23.5 mmHg at 1-month post-BRTO, accompanied by ascites retention and development of portal hypertensive gastropathy. Thereafter, PSE was performed, followed by NSBB administration, to control the elevated portal venous pressure following BRTO. Postoperatively, the patient's ascites and portal hypertensive gastrophy improved after splenic artery embolization, which eventually disappeared after the additional administration of NSBBs 1 month later. The HVPG finally decreased to 16.9 mmHg; the Child-Pugh score, MELD-Na score and blood ammonia level improved to 7, 11 and 22 μg/dL, respectively, after all therapies. BRTO significantly improved the symptoms of portal-systemic liver failure with refractory encephalopathy. PSE and NSBB administration could contribute to additional amelioration of hepatic function and successful management of complications induced by portal hemodynamic changes following BRTO.

Abstract
Diamond Blackfan Anemia (DBA) is a congenital bone marrow failure syndrome associated with ribosomal gene mutations that lead to ribosomal insufficiency. DBA is characterized by anemia, congenital anomalies, and cancer predisposition. Treatment for DBA is associated with significant morbidity. Here, we report the identification of Nemo-like kinase (NLK) as a potential target for DBA therapy. To identify new DBA targets, we screen for small molecules that increase erythroid expansion in mouse models of DBA. This screen identified a compound that inhibits NLK. Chemical and genetic inhibition of NLK increases erythroid expansion in mouse and human progenitors, including bone marrow cells from DBA patients. In DBA models and patient samples, aberrant NLK activation is initiated at the Megakaryocyte/Erythroid Progenitor (MEP) stage of differentiation and is not observed in non-erythroid hematopoietic lineages or healthy erythroblasts. We propose that NLK mediates aberrant erythropoiesis in DBA and is a potential target for therapy. Diamond Blackfan Anemia (DBA) is a congenital bone marrow failure syndrome that is associated with anemia. Here, the authors examine the role of Nemo-like kinase (NLK) in erythroid cells in the pathogenesis of DBA and as a potential target for therapy.

Abstract
Background:A polymorphism onFTO(OMIM 610966) was reported as a causal variant for obesity, plays a critical rule not only in amount of adipose tissue but also in function of mitochondrial thermogenesis1.Objectives:To examine the association of the genotype on a single nucleotide polymorphism onFTOwith bone health.Methods:FTO rs1421085 polymorphism was genotyped in 1,601 community-dwelling Japanese participants. This cross-sectional study was nested in Nagasaki Islands Study, which is a prospective cohort in Goto City, in islands of Japan. Participants were recruited at medical check-ups for community dwelling population.Bone mass of the calcaneus was evaluated with stiffness index calculated using a quantitative ultrasound measurement. Low bone mass was defined as a stiffness index less than 80 % of the young adult mean.Sera and peripheral blood mononuclear cells were obtained. The SNP of rs1421085 was genotyped using hydrolysis probe. The chi-squared test was used to determine whether the variants were in equilibrium in that population. Trend for the median of BMI among genotypes was assessed using the Jonckheere-Terpstra test. Potential associations between FTO polymorphism and overweight and between the polymorphism and low bone mass were evaluated using logistic regression. All analyses were carried out using SPSS 23.Results:Genotype and allele frequencies for the polymorphism were in Hardy-Weinberg equilibrium (minor allele frequency 0.16, p = 0.40) in 1,601 community-dwelling persons (mean age was 68.5 years in men and 68.1 years in women).There were significant associations between the minor allele and higher median of BMI on dose dependent manner in men (p = 0.04 for trend in men and p = 0.10 for trend in women, respectively), and between the minor allele and overweight (>25 in BMI, OR 1.52, 95%CI 1.07 2.14, p=0.02 in men, OR 1.48, 95%CI 1.16 1.95, p=0.01 in women).Logistic regression analysis showed a significant protective association in men with carriers of minor allele against low bone mass after an adjustment for age and BMI (OR 0.63, 95%CI 0.44 0.90, p=0.01 in men, not significant in women).Conclusion:Our study indicated significant associations of the polymorphism onFTOwith BMI and bone mass among community dwelling men. The polymorphism may play a rule in a part of bone health with higher BMI and other beneficial functions.References:[1]N Engl J Med. 2015; 373: 895-907Disclosure of Interests:None declared

Abstract
Investigating slow earthquake activity in subduction zones provides insight into the slip behavior of megathrusts, which can provide important clues about the rupture extent of future great earthquakes. Using the S-net ocean-bottom seismograph network along the Japan Trench, we mapped a detailed distribution of tectonic tremors, which coincided with very-low-frequency earthquakes and a slow slip event. Compiling these and other related observations, including repeating earthquakes and earthquake swarms, we found that the slow earthquake distribution is complementary to the Tohoku-Oki earthquake rupture. We used our observations to divide the megathrust in the Japan Trench into three along-strike segments characterized by different slip behaviors. We found that the rupture of the Tohoku-Oki earthquake, which nucleated in the central segment, was terminated by the two adjacent segments.

Abstract
Background and Objectives Computational clinical trial (CCT) in the field of laser medicine promotes clinical application of novel laser devices, because this trial carried out based on numerical modeling of laser-tissue interactions and simulation of a series of treatment process. To confirm the feasibility of the computational clinical trial of skin treatment with a novel picosecond laser, this paper presents an evaluation method of the safety. Study Design/Materials and Methods In this method, the light propagation and thermal diffusion process after ultrashort light pulse irradiation to a numerical skin model is calculated and the safety based on the photothermal damage is evaluated by computational modeling and simulation. As an example, the safety of a novel picosecond laser device was examined by comparing with several laser devices approved for clinical use. Results The ratio of the maximum thermal damage induced by picosecond laser irradiation was 1.2 × 10-2 % at the epidermis, while that caused by approved laser irradiation was 99 % at the capillary vessels. The numerical simulation demonstrated that less thermal damage was observed compared with the approved devices. The results show the safety simulated by photothermal damage calculation was consistent with the reported clinical trials. Conclusions This computational clinical trial shows the feasibility of applying computational clinical trials for the safety evaluation of novel medical laser devices.

Abstract
Background We assessed the non-inferiority of accelerated fractionation (AF) (2.4 Gy/fraction) compared with standard fractionation (SF) (2 Gy/fraction) regarding progression-free survival (PFS) in patients with T1-2N0M0 glottic cancer (GC). Patients and methods In this multi-institutional, randomized, phase III trial, patients were enrolled from 32 Japanese institutions. Key inclusion criteria were GC T1-2N0M0, age 20-80, Eastern Cooperative Oncology Group performance status of 0-1, and adequate organ function. Patients were randomly assigned to receive either SF of 66-70 Gy (33-35 fractions), or AF of 60-64.8 Gy (25-27 fractions). The primary end point was the proportion of 3-year PFS. The planned sample size was 360 with a non-inferiority margin of 5%. Results Between 2007 and 2013, 370 patients were randomized (184/186 to SF/AF). Three-year PFS was 79.9% (95% confidence interval [CI] 73.4-85.4) for SF and 81.7% (95% CI 75.4-87.0) for AF (difference 1.8%, 91% CI-5.1% to 8.8%; one-sided P = 0.047 > 0.045). The cumulative incidences of local failure at 3 years for SF/AF were 15.9%/10.3%. No significant difference was observed in 3-year overall survival (OS) between SF and AF. Grade 3 or 4 acute and late toxicities developed in 22 (12.4%)/21 (11.5%) and 2 (1.1%)/1 (0.5%) in the SF/AF arms. Conclusion Although the non-inferiority of AF was not confirmed statistically, the similar efficacy and toxicity of AF compared with SF, as well as the practical convenience of its fewer treatment sessions, suggest the potential of AF as a treatment option for early GC.

Abstract
Abstract
Background
Presepsin, a subtype of soluble CD14, is an inflammatory marker, which largely reflects monocytic activation. Presepsin appears to be an accurate diagnostic marker of sepsis, but its clinical significance remains unclear in cardiovascular disease.
Purpose
This prospective study aimed to investigate the predictive value of plasma presepsin levels on admission to medical (non-surgical) cardiac intensive care units (MCICUs) for short-term mortality.
Methods
We examined 1560 patients hospitalized in MCICUs and measured the baseline plasma presepsin levels at admission.
Results
Acute coronary syndrome was present in 46% of the patients, and acute decompensated heart failure in 36%. Before MCICUs admission, emergent coronary angiography or percutaneous coronary intervention was performed in 36%, mechanical ventilation was required for respiratory insufficiency in 2.1%, and intraaortic balloon pumps were needed for hemodynamic instability in 8.9%. During 6 months after admission, there were 113 (7.2%) deaths. Patients who died were older (median: 77 vs. 71 years, P<0.0001); had higher levels of presepsin (263 vs. 119 pg/mL, P<0.0001), B-type natriuretic peptide (BNP: 696 vs. 186 pg/mL, P<0.0001), high-sensitivity troponin T (hsTnT: 81 vs. 47 pg/mL, P=0.004), and high-sensitivity C-reactive protein (13.8 vs. 2.2 mg/L, P<0.0001); and had lower levels of estimated glomerular filtration rate (50 vs. 65 mL/min/1.73m2, P<0.0001) and left ventricular ejection fraction (43% vs. 51%, P<0.0001) than those of the survivors. In the multivariate Cox regression analysis, higher levels of presepsin (P=0.0002), BNP (P=0.04), and hsTnT (P=0.009) were all independent predictors of 6-month deaths. Quartiles of presepsin levels were associated with higher mortality rates within 6 months after admission (Table). Adding presepsin levels to a baseline model that included established risk factors, BNP, and hsTnT further enhanced reclassification (P=0.004) and discrimination (P=0.003) beyond that of the baseline model.
Mortality rates according to presepsin Presepsin quartile 1st 2nd 3rd 4th P value ≤80 pg/mL 81–124 pg/mL 125–232 pg/mL >232 pg/mL 1-month mortality 0.8% 2.0% 3.3% 8.0% <0.0001 6-month mortality 0.8% 3.8% 8.2% 16.3% <0.0001
Conclusions
Presepsin levels at admission could improve the prediction of short-term mortality in patients hospitalized at MCICUs.

A novel therapeutic strategy for esophageal varices using endoscopic treatment combined with splenic artery embolization according to the Child-Pugh classification. PLoS One 2019; 14:e0223153.

Abstract
Variceal hemorrhage may cause high rebleeding and mortality rates. Preventing the first episode of variceal bleeding is mandatory in patients with high-risk esophageal varices (EV). This study aimed to identify factors that predict the recurrence of EV after endoscopic treatment (ET), and to develop a reasonable therapeutic strategy for EV in cirrhosis. From January 2012 to December 2014, 45 patients with cirrhosis and high-risk EV underwent ET, including sclerotherapy and/or ligation. Statistical analyses identified factors associated with the recurrence of EV after ET, and the Kaplan-Meier method determined the cumulative variceal recurrence rates. The 1-, 2-, and 3-year cumulative posttreatment recurrence rates for EV were 13.3%, 29.5%, and 32.2%, respectively. No significant differences were evident between the patients with and without variceal recurrences at 1-year posttreatment. The multivariate regression analyses identified a history of partial splenic embolization (PSE) and the pretreatment Child-Pugh classification as independent predictors of variceal recurrences at 2 years (p < 0.05) and 3 years (p < 0.05) posttreatment. While EV did not recur after ET and splenic artery embolization in cases with Child-Pugh class A, the overall posttreatment variceal recurrence rates were 0% and 66.7% when PSE was performed before and after ET, respectively, in those with Child-Pugh class B or C. Splenic artery embolization significantly reduced the hepatic venous pressure gradient and markedly lowered the Child-Pugh score in 15 patients. Adjunctive PSE and pretreatment Child-Pugh class A could be independently associated with reduced cumulative recurrence rates of EV post-ET. From the perspectives of portal hemodynamics and hepatic function, splenic artery embolization before or after ET could prevent posttreatment variceal recurrence in patients with Child-Pugh class A, and PSE before ET could achieve the long-term eradication of EV following ET in those with Child-Pugh class B or C.

Large Enhancement of Thermoelectric Efficiency Due to a Pressure-Induced Lifshitz Transition in SnSe. PHYSICAL REVIEW LETTERS 2019; 122:226601.

Abstract
The Lifshitz transition, a change in Fermi surface topology, is likely to greatly influence exotic correlated phenomena in solids, such as high-temperature superconductivity and complex magnetism. However, since the observation of Fermi surfaces is generally difficult in the strongly correlated systems, a direct link between the Lifshitz transition and quantum phenomena has been elusive so far. Here, we report a marked impact of the pressure-induced Lifshitz transition on thermoelectric performance for SnSe, a promising thermoelectric material without a strong electron correlation. By applying pressure up to 1.6 GPa, we have observed a large enhancement of the thermoelectric power factor by more than 100% over a wide temperature range (10-300 K). Furthermore, the high carrier mobility enables the detection of quantum oscillations of resistivity, revealing the emergence of new Fermi pockets at ∼0.86 GPa. The observed thermoelectric properties linked to the multivalley band structure are quantitatively reproduced by first-principles calculations, providing novel insight into designing the SnSe-related materials for potential valleytronic as well as thermoelectric applications.

Abstract
A flexuous virus was detected in a Cnidium officinale plant in Japan showing mosaic symptoms. The virus was assigned to the genus Potexvirus based on analysis of its complete nucleotide sequence. The genomic RNA of the virus was 5,964 nucleotides in length, excluding the 3'-terminal poly(A) tail. It contained five open reading frames (ORFs), consistent with other members of Potexvirus. The ORF sequences differ from those of previously reported potexviruses. Phylogenetic analysis indicated that the polymerase of the virus is closely related to that of strawberry mild yellow edge virus; and the CP, to those of both yam virus X and vanilla virus X. We propose that this virus be designated as "cnidium virus X" (CnVX).

Abstract
Abstract
[Introduction] Non-malignant proliferative lesions in the breast have been implicated in the development of invasive breast cancer. Previous studies showed that adjacent atypical proliferative lesions and breast cancers shared common genetic alterations, suggesting that these evolved from the same ancestral cell. However, the clonal structure of atypical proliferative lesions and their clonal dynamics during progression to cancer are poorly understood. In this study, we compared genetic profiles (with and without pathogenic germline mutations) of normal mammary ducts, non-malignant proliferative lesions, and cancer tissues from the same patients to illustrate the clonal evolution of cancer from a non-malignant epithelial cell.
[Methods] Multiple samples were collected from different proliferative lesions within the cancer-borne breast, including invasive cancers, using micro-dissection from formalin-fixed, paraffin-embedded surgical specimens. Somatic mutations and copy number alterations (CNAs) were then evaluated by whole exome sequencing.
[Results] We analyzed a total of 34 samples from 5 premenopausal females carrying estrogen receptor-positive cancers, where the samples were obtained from normal ducts (N = 6), non-atypical (N = 1) and atypical (N = 8) proliferative lesions, and non-invasive (N = 16) and invasive (N = 3) cancers. The number of somatic mutations per sample ranged from 1 to 276 and increased with disease progression, regardless of the germline mutation status. Two cases with bilateral cancers had a pathogenic germline mutation of either BRCA2 or TP53, where no somatic mutations or CNAs were shared by individual proliferative lesions, suggesting multifocal independent cancerous evolutions. By contrast, in the remaining three unilateral cases, no pathogenic germline mutations were detected, but all proliferative lesions, which were separated by a distance of 7-25 mm, shared one or more driver alterations, such as an AKT1 mutation (UID: KU01), concurrent 1q gain and 16q loss (der(1;16)) (UID: KU02), and a GATA3 mutation and der(1;16) (UID: KU03), while harboring private mutations and/or CNAs of their own. The phylogenetic analysis based on the number of shared mutations predicted an early origin of these founder mutations, which frequently predated decades before the onset of cancer.
[Conclusions] Our results suggest that early breast cancer development is shaped by the evolution of multiple precancerous clones. These clones are originated from a common ancestor that acquired a founder mutation long before the onset of cancer, followed by branching evolution of multiple clones that acquired additional driver mutations of their own, from which an invasive cancer ultimately develops. In hereditary cases, this process is thought to be substantially promoted multi-focally from within the entire breasts by a germline mutation shared by all mammary cells, frequently resulting in bilateral and/or multifocal breast cancers. Our findings provide unique insight into the early development of breast cancer.

Abstract
Background We previously reported regenerative therapies for decompensated cirrhosis based on peripheral venous drip infusion using non-cultured whole bone marrow (BM) cells, or the less invasive cultured BM-derived mesenchymal stem cells (BMSCs). Here, we assessed the efficacy and safety of hepatic arterial infusion using cultured autologous BMSCs, comparing it with peripheral infusion, using our established canine liver fibrosis model. Methods Canine BM cells were harvested and cultured, and the resultant BMSCs were returned to carbon tetrachloride (CCl4)-induced liver cirrhosis model canines via either a peripheral vein (Vein group) or hepatic artery (Artery group). A variety of assays were performed before and 4, 8, and 12 weeks after BMSC infusion, and liver fibrosis and indocyanine green (ICG) half-life (t1/2) were compared to those in a control group that received CCl4 but not BMSCs. The safety of this approach was evaluated by contrast-enhanced computed tomography (CT) and serial blood examinations after infusion. Results Four weeks after infusing BMSCs, a significant improvement was observed in the Vein group (n = 8) compared to outcome in the Control group (n = 10), along with a decrease in ICG t1/2. In the Artery group (n = 4), ICG t1/2 was significantly shorter than that in the Vein group at 8 weeks (Δt1/2: −3.8 ± 1.7 min vs. +0.4 ± 2.4 min; p < 0.01) and 12 weeks (Δt1/2: −4.2 ± 1.7 min vs. +0.4 ± 2.7 min; p < 0.01) after BMSC administration. Post-infusion contrast-enhanced CT showed no liver infarction, and blood tests showed no elevations in either serum lactate dehydrogenase concentrations or hypercoagulability. Conclusions We confirmed the efficacy and safety of the hepatic arterial infusion of cultured autologous BMSCs using a canine model, thereby providing non-clinical proof-of-concept.

Abstract
BACKGROUND AND AIM This study aimed to identify predictors of model for end-stage liver disease sodium score reductions and improvements in vital prognoses following portosystemic shunt occlusion in portal hypertension patients. METHODS Seventy cirrhotic patients with major portosystemic shunts and a mean model for end-stage liver disease sodium score of 10.5 underwent balloon-occluded retrograde transvenous obliteration between February 2008 and March 2017. We calculated the scores before and 1 month after shunt occlusion. The long-term outcomes were monitored, and vital prognoses were analyzed. RESULTS The model for end-stage liver disease sodium score did not change significantly 1 month post-balloon-occluded retrograde transvenous obliteration, and the score decreased postoperatively in 31 (44.3%) patients. Univariate analyses showed that decline in the score after portosystemic shunt occlusion was strongly associated with hepatic encephalopathy as a procedural indication, lower liver volumes, and lower liver stiffness levels measured by transient elastography before treatment (P < 0.05). Multivariate logistic regression analysis identified preoperative liver stiffness level as an independent predictor of model for end-stage liver disease sodium score amelioration following balloon-occluded retrograde transvenous obliteration (P < 0.05), and receiver operating characteristic curve analysis determined a liver stiffness cutoff value of 21.6 kPa, with a sensitivity of 76.0% and specificity of 69.6%. The Kaplan-Meier method determined that overall survival rates after treatment in patients with liver stiffness < 21.6 kPa were significantly higher than in patients with liver stiffness ≥ 21.6 kPa (P < 0.05). CONCLUSIONS Liver stiffness measured by transient elastography may predict improvements in model for end-stage liver disease sodium scores and in survival rates after portosystemic shunt occlusion in portal hypertension patients.

Abstract
AIM To compare the clinical characteristics of patients with hepatic encephalopathy (HE) and those with gastric varices (GV) before and after balloon-occluded retrograde transvenous obliteration (BRTO). METHODS Eighty cirrhotic patients who underwent BRTO, including 42 men and 38 women, and whose mean age was 68 years, comprised the HE (n = 18) and GV (n = 62) groups. The patients' data before and 1 month after BRTO were analyzed. RESULTS Before BRTO, the groups did not differ in their portal flow volume (PFV) or hepatic venous pressure gradient (HVPG). The portal vein (PV) was narrower and the splenic vein (SpV) was wider in the HE group than in the GV group. The SpV flow was hepatofugal in 75.0% of HE patients and hepatopetal in 92.6% of GV patients. The Child-Pugh (CP) score of the HE group was significantly higher than that of the GV group pre-BRTO. After BRTO, the PFV and HVPG increases in the HE group equaled those in the GV group, and the PV dilation was similar in both groups. Conversely, the SpV was significantly contracted for HE patients, but significantly dilated for GV patients. Postoperatively, the SpV flow was hepatopetal in all patients. Compared to that in the GV group, the CP score decreased markedly in the HE group, and no significant increases in complications occurred post-BRTO for HE patients. CONCLUSIONS The HE patients showed distinct portal-splenic hemodynamics before and after BRTO. Balloon-occluded retrograde transvenous obliteration markedly improved hepatic function in the HE group compared with the GV group.
