Abstract
Hepatocellular carcinoma (HCC) is a common malignancy with a poor prognosis, particularly in patients with advanced-stage disease, elderly individuals and/or in those with poor liver function. Immune checkpoint inhibitor-containing therapies, such as atezolizumab, an anti-programmed death ligand-1 monoclonal antibody, plus bevacizumab, an anti-vascular endothelial growth factor monoclonal antibody, may be effective and safe therapeutic options for elderly patients with advanced-stage HCC. The present study reports the case of a male patient his 80s who consumed alcohol with unresectable advanced-stage HCC who received combination therapy comprising atezolizumab plus bevacizumab for 6 months. The patient achieved a complete response despite the discontinuation of treatment due to nephrotoxicity. It is critical for patients with HCC and a Child-Pugh A grade to continue therapy for HCC, even if they are older. The development of more effective therapies is required for patients with advanced-stage HCC with a worse liver function than those with a Child-Pugh A grade. The case described in the present study demonstrates the need for obtaining further evidence regarding the efficacy and safety of the combination therapy including atezolizumab plus bevacizumab for elderly patients with advanced-stage HCC.

Abstract
PURPOSE Identification of drainage vessels is useful for differential diagnosis of hepatic tumors. Direct drainage to the hepatic vein has been reported to occur in focal nodular hyperplasia (FNH), but studies evaluating the drainage veins of FNH are limited. We aimed to investigate the detection rate of the FNH drainage vein and the factors related to visualization of the drainage vein on contrast-enhanced ultrasound (CEUS). METHODS Fifty consecutive patients with 50 FNH lesions were retrospectively evaluated in this study. We calculated and compared the detection rate of the FNH drainage vein on CEUS, contrast-enhanced magnetic resonance imaging (CEMRI), and contrast-enhanced computed tomography (CECT), and identified the factors correlated with visualization of the FNH drainage vein on CEUS by using multivariate logistic regression analyses. RESULTS Visualization of the drainage vein was confirmed in 31 of 50 lesions (62%) using CEUS, three of 44 lesions (6.8%) using CEMRI, and one of 18 lesions (5.6%) using CECT. The detection rate of the FNH drainage vein on CEUS was significantly higher than that on CEMRI and CECT (p < 0.001). Multivariate analysis identified lesion size (≥ 25 mm) and detection of the spoke-wheel pattern on Doppler US as independent factors for drainage vein detection in FNH. CONCLUSION Our study showed that rapid FNH drainage to the hepatic vein was observed at a relatively high rate on CEUS, suggesting that CEUS focusing on detection of drainage veins is important for diagnosing FNH.

Abstract
We have previously reported that chromatin licensing and DNA replication factor 1 (CDT1) is associated with the postoperative recurrence of hepatocellular carcinoma (HCC). Based on this fact, we verified whether CDT1 mRNA expression is also associated with HCC development from chronic hepatitis C (CHC) and liver cirrhosis (LC). There were 142 cases with CHC or LC who underwent liver biopsy. Detection of CDT1 mRNA in liver was performed by RT-qPCR using frozen liver biopsy tissues. We examined the association between the CDT1 mRNA expression and clinical conditions and long-term outcome. We then examined the association between serum cytokine/chemokine levels and CDT1 mRNA expression in 58 cases. The cumulative incidence rates of HCC development in cases with CDT1 mRNA in the low expression group showed significantly lower than those in the high expression group (p = 0.0391). A significant correlation was found between CDT1 mRNA expression and the extent of proliferation of atypical hepatocytes in hematoxylin and eosin-stained sections (p<0.0001). CDT1 mRNA expression has been associated with cytokines involved in tumorigenesis in experimental and human cancers. We found that cases with high CDT1 mRNA expression were at risk for developing HCC, even if they were CHC or LC.

Abstract
PURPOSE No studies of the relationship between grayscale sonographic findings and pancreatic fat content have been reported to date. This study aimed to investigate the correlation between echogenicity and fat content of resected specimens using quantitative analysis. METHODS Forty-two consecutive patients who underwent pancreatoduodenectomy or distal pancreatectomy for pancreatic tumors were enrolled in this study. Ultrasonographic images were compared with quantitative pathological analysis. Subjective evaluation of echogenicity was classified as hypoechoic, isoechoic, hyperechoic, and super hyperechoic. The total and intralobular fat areas were measured. RESULTS The mean, median, modal, minimum, and maximum ultrasound gray values correlated with the proportion of total fat area (r = 0.349; 0.357, 0.486, 0.466, and 0.347; p = 0.024, 0.020, 0.014, 0.019, and 0.089, respectively), but did not correlate with the proportion of intralobular fat area. Subjective classification was correlated with median gray value (p < 0.001), intralobular fat area (p = 0.118), and total fat area (p = 0.011). Cases were classified as hypoechoic (n = 3), isoechoic (n = 7), hyperechoic (n = 30), and super hyperechoic (n = 2). The subjective classification was correlated with the median gray value (p < 0.001) and total fat area (p = 0.005), and not correlated with the intralobular fat area (p = 0.118). Hyperechoic or super hyperechoic pancreatic parenchyma contains over 19.7% fat. Computed tomography values correlated with the proportion of intralobular fat area (r = - 0.479, p = 0.004) and total fat area (r = - 0.541, p < 0.001). CONCLUSION Echogenicity classified based on subjective evaluation and image analysis were correlated with the proportion of fat in the pancreas.

Abstract
Sex hormones, such as androgens and estrogens, are predominantly produced in the gonads (ovaries and testes) and adrenal cortex. Endocrine-disrupting chemicals (EDCs) are substances that mimic, block, or interfere with hormones in the endocrine systems of humans and organisms. EDCs mainly act via nuclear receptors and steroidogenesis-related enzymes. In the OECD conceptual framework for testing and assessment of EDCs, several well-known assays are used to identify the potential disruption of nuclear receptors both in vivo and in vitro, whereas the H295R steroidogenesis assay is the only assay that detects the disruption of steroidogenesis. Forskolin and prochloraz are often used as positive controls in the H295R steroidogenesis assay. Decamethylcyclopentasiloxane (D5) was suspected one of EDCs, but the effects of D5 on steroidogenesis remain unclear. To establish a short-term in vivo screening method that detects the disruption of steroidogenesis, rats in the present study were fed a diet containing forskolin, prochloraz, or D5 for 14 days. Forskolin increased plasma levels of 17β-estradiol (E2) and testosterone as well as the mRNA level of Cyp19 in both the adrenal glands and ovaries. Prochloraz induced the loss of cyclicity in the sexual cycle and decreased plasma levels of E2 and testosterone. D5 increased E2 levels and shortened the estrous cycle in a dose-dependent manner; however, potential endocrine disruption was not detected in the H295R steroidogenesis assay. These results demonstrate the importance of comprehensively assessing the endocrine-disrupting effects of chemicals on steroidogenesis in vivo.

Abstract
BACKGROUND Hyperuricemia (HU) and hypertension (HTN) contribute to atherosclerotic cardiovascular disease, and both are also involved in the onset and development of atrial fibrillation (AF). OBJECTIVE In the present study, we investigated the association between risk factors for atherosclerosis [including HU, HTN, blood pressure and serum uric acid (UA) levels] and paroxysmal atrial fibrillation (Paro-AF) or persistent atrial fibrillation (Pers-AF) in patients who underwent coronary computed tomography angiography (CCTA). METHODS We enrolled 263 patients from the Fukuoka University-CCTA-AF (FU-CCTA-AF Registry) who underwent CCTA prior to AF ablation therapy. AF was classified as either Paro-AF (≤ 7 days) or Pers-AF (> 7 days). HU was diagnosed by a serum UA level > 7.0 mg/dl, and coronary artery disease (CAD) was diagnosed when CCTA results showed ≥ 50% significant coronary artery stenosis. The number of significantly diseased coronary artery vessels (VD), the Gensini score and the coronary artery calcification score (CACS) were measured. Left atrial morphology was also evaluated. RESULTS Diastolic blood pressure and HbA1c in the Pers-AF group were significantly higher than those in the Paro-AF group. The Pers-AF group showed a significantly higher prevalence of HU and higher UA levels than the Paro-AF group. In a multivariate logistic regression analysis, HU was an independent associated factor to Pers-AF (odds ratio: 2.023, 95% confidence interval: 1.055-3.881, p = 0.034), while HTN was not. CONCLUSION In patients with AF, HU is associated with Pers-AF.

Abstract
Human rotavirus strains having the unconventional G3P[6] genotype have been sporadically detected in diarrheic patients in different parts of the world. However, the full genomes of only three human G3P[6] strains from Asian countries (China, Indonesia, and Vietnam) have been sequenced and characterized, and thus the exact origin and evolution of G3P[6] strains in Asia remain to be elucidated. Here, we sequenced and characterized the full genome of a G3P[6] strain (RVA/Human-wt/JPN/SO1199/2020/G3P[6]) found in a stool sample from a 3-month-old infant admitted with acute gastroenteritis in Japan. On full genomic analysis, strain SO1199 was revealed to have a unique Wa-like genogroup configuration: G3-P[6]-I5-R1-C1-M1-A8-N1-T1-E1-H1. VP6 genotype I5 and NSP1 genotype A8 are commonly found in porcine rotavirus strains. Furthermore, phylogenetic analysis demonstrated that all 11 genes of strain SO1199 were closely related to those of porcine and/or porcine-like human rotaviruses and thus appeared to be of porcine origin. Thus, strain SO1199 was shown to possess a porcine-like genomic backbone and thus is likely to be the result of interspecies transmission of a porcine rotavirus strain. Of note is that all 11 genes of strain SO1199 were phylogenetically located in clusters, distinct from those of the previously identified porcine-like human G3P[6] strains from around the world including Asia, suggesting the occurrence of independent porcine-to-human zoonotic transmission events. To our knowledge, this is the first report on full genome-based characterization of a human G3P[6] strain that has emerged in Japan. Our findings revealed the diversity of unconventional human G3P[6] strains in Asia, and provide important insights into the origin and evolution of G3P[6] strains.

Abstract
We previously reported that chromatin licensing and DNA replication factor 1 (CDT1) expression was associated with the extent of proliferation of atypical hepatocytes and the time to postoperative recurrence in cases of hepatocellular carcinoma (HCC). This study aimed to clarify the clinical significance or pathogenesis of CDT1 expression in both non-cancerous and cancerous liver in HCC cases, including previously published data. We investigated the association between the expression of CDT1 in non-cancerous or cancerous liver tissues and histologic findings or biochemical examination results in 62 cases. We also examined the dual localization between CDT1 and FbxW7, P57kip2, P53 and c-Myc by confocal laser scanning microscopy. CDT1 mRNA expression was significantly higher in cancerous liver than in non-cancerous liver (p<0.0001). Elevated CDT1 mRNA expression indicates a significantly degree of inflammatory cell infiltration within lobules, along with elevated serum transaminase levels, and hepatic spare decline. CDT1 mRNA was highly expressed in a group of poorly differentiated cancer cells. CDT1 co-localized with P57kip2, Fbwx7, P53 and c-Myc in the nucleus or cytoplasm of hepatocytes and cancer cells. We found that CDT1 mRNA expression could represent the degree of hepatic spare ability and the high carcinogenic state.

Abstract
We have reported that extent of proliferation of atypical hepatocytes (POAH) in non-cancerous liver in hepatocellular carcinoma and chromatin licensing and DNA replication factor 1 (CDT1) are associated with postoperative recurrence. Here, we investigated whether extent of POAH and expression of CDT1 in liver are also associated with chemically induced liver cancer in rats. Male Fisher strain rats were orally administered diethylnitrosamine (DEN) in their drinking water and sacrificed at 6, 8, 12, or 14 weeks after start of DEN administration. We serially monitored changes in extent of POAH, CDT1 expression by immunohistochemistry (IHC), and CDT1 mRNA expression in liver by real-time quantitative PCR. The extent of POAH in liver progressed in a time-dependent manner after start of DEN administration. CDT1 expression was higher at 8 weeks than at 6 weeks by IHC, suggesting that CDT1 expression may be a marker of POAH severity. CDT1 mRNA expression in liver was significantly higher at 12 weeks than at 6 weeks (p<0.0001). We found that extent of POAH and the expression of CDT1 are also important factors in the development of chemical carcinogen-induced hepatocarcinogenesis. Furthermore, the association with POAH and CDT1 expression in carcinogenic process is important regardless of the cause of hepatocarcinogenesis.

Abstract
OBJECTIVES To investigate the association between plasma N-terminal pro-atrial natriuretic peptide concentration and glomerular filtration rate in dogs. MATERIALS AND METHODS Dogs were classified into four categories by bodyweight. Dogs were divided into four groups (Groups 1 to 4) based on glomerular filtration rate estimates using plasma iohexol clearance per bodyweight category. Generalised linear models were built to explore the relationship between plasma N-terminal pro-atrial natriuretic peptide concentration and glomerular filtration rate and the effect of confounders on plasma N-terminal pro-atrial natriuretic peptide concentration. RESULTS Fifty-three dogs were included (Group 1, 25; Group 2, seven; Group 3, five; and Group 4, 16). The medians (interquartile range) N-terminal pro-atrial natriuretic peptide concentrations for Groups 1 to 4 were 7224 pg/mL (4766 to 10,254 mg/dL), 8958 pg/mL (4935 to 11,271 mg/dL), 9280 pg/mL (9195 to 10,384 mg/dL) and 12,683 pg/mL (9133 to 19,217 mg/dL), respectively. Group 4, estimated to have the highest reduction in glomerular filtration rate, had a higher plasma N-terminal pro-atrial natriuretic peptide concentration than Groups 1 to 3. Based on the final generalised linear model, influencing factors for plasma N-terminal pro-atrial natriuretic peptide concentration were plasma iohexol clearance (-0.136; 95% confidence interval, -0.227 to -0.046) and bodyweight (-0.058; 95% confidence interval, -0.098 to -0.018). CLINICAL SIGNIFICANCE N-terminal pro-atrial natriuretic peptide concentration is associated with the glomerular filtration rate.

Abstract
High-density lipoprotein (HDL) functionality has been reported to be associated with coronary artery disease (CAD). However, little is known about the impact of HDL functionality on coronary atherosclerosis. Thirty-eight type 2 diabetic patients with CAD who underwent percutaneous coronary intervention were examined. Coronary atheroma burden and plaque composition of the culprit lesions were assessed using conventional gray-scale and integrated backscatter intravascular ultrasound. HDL-mediated cholesterol efflux capacity (HDL-CEC) and HDL antioxidant capacity, estimated as HDL inflammatory index (HII), were examined. The associations between HDL functionality and coronary plaques were analyzed using multivariate data analysis, including principal components analysis and orthogonal partial least squares (OPLS) models. Percent atheroma volume was correlated with HDL-CEC (r = 0.34, p = 0.04) but not with HII (p = 0.65). The OPLS model demonstrated that the percentage lipid volume was significantly associated with HDL functionality [coefficient (95% confidence interval); HDL-CEC: -0.26 (-0.49, -0.04); HII: 0.34 (0.08, 2.60), respectively]. HII exhibited the highest variable importance in projection score, indicating the greatest contribution. HDL functionality was associated with coronary plaque composition, a key component of plaque vulnerability. Our findings highlight the potential importance of HDL functionality for coronary plaque stabilization.

Abstract
Background and Objectives: Muscle cramps are often observed in patients with liver diseases, especially advanced liver fibrosis. The exact prevalence of muscle cramps in outpatients with liver diseases in Japan is unknown. Patients and Methods: This study examined the prevalence of, and therapies for, muscle cramps in outpatients with liver diseases in Tokyo, Japan. A total of 238 outpatients with liver diseases were retrospectively examined. We investigated whether they had muscle cramps using a visual analog scale (VAS) (from 0, none, to 10, strongest), and also investigated their therapies. Results: Muscle cramps were observed in 34 outpatients with liver diseases (14.3%); their mean VAS score was 5.53. A multivariate analysis demonstrated that older age (equal to or older than 66 years) was the only significant factor as-sociated with muscle cramps. The prevalence of muscle cramps among patients with liver diseases seemed not to be higher. The problem was that only 11 (32.4%) of 34 outpatients received therapy for their muscle cramps. Conclusions: Only age is related to muscle cramps, which is rather weak, and it is possible that this common symptom may not be limited to liver disease patients.

Abstract
Varicella-zoster virus (VZV) infection in adults or immunocompromised patients has a more severe presentation compared to the mild disease in children. To the best of our knowledge, no reports have described the clinical course of VZV pneumonia focusing on time course of skin rash, chest computed tomography (CT) findings, and viral load. Furthermore, no reports have described the reactivation of human herpes virus 6 (HHV-6) in VZV pneumonia. Here, we report a case of severe VZV pneumonia that resulted in reactivation of HHV-6 in a patient with rheumatoid arthritis (RA). A 66-year-old female treated for RA was admitted to our hospital with papules. Her chest CT showed granular infiltrates, micronodules, and ground-glass opacities. The day after admission, because the typical skin rashes and chest CT findings were observed, she was diagnosed with VZV pneumonia and treated with acyclovir. Her skin rash then crusted over five days and entered the healing process, whereas it took approximately two weeks for her respiratory condition and chest CT findings to improve. In addition, VZV deoxyribonucleic acid (DNA) gradually decreased with treatment. On the 34th day of admission, VZV DNA was not found in the serum sample but remained in the sputum sample. Furthermore, although reactivation of HHV-6 was observed, viremia resolved without treatment. Clinicians should be able to recognize the differences in the improvement of skin rashes, respiratory status, and chest CT findings. In addition, treatment for HHV-6 reactivation should be carefully determined for each case.

Abstract
Post-synthesis modification of polymers streamlines the synthesis of functionalized polymers, but is often incomplete due to the negative polymer effects. Developing efficient polymer reactions in artificial systems thus represents a long-standing objective in the fields of polymer and material science. Here, we show unprecedented macrocycle-metal-complex-catalyzed systems for efficient polymer reaction that result in 100% transformation of the main chain functional groups presumably via a processive mode reaction. The complete polymer reactions were confirmed in not only intramolecular reaction (hydroamination) but also intermolecular reaction (hydrosilylation) by using Pd- and Pt-macrocycle-catalyzed systems. The most fascinating feature of the both reactions is that higher-molecular-weight polymers reach completion faster. Various studies suggested that the reactions occur in the catalyst cavity via the formation of a supramolecular complex between the macrocycle catalyst and polymer substrate like pseudorotaxane, which should be of characteristic of the efficient polymer reactions progressing in a processive mode.

Abstract
2,2-Bis(4-hydroxyphenyl)propane (bisphenol A; BPA) is an environmental endocrine-disrupting chemical. It mimics the effects of estrogen at multiple levels by activating estrogen receptors (ERs); however, BPA also affects the proliferation of human breast cancer cells independent of ERs. Although BPA inhibits progesterone (P4) signaling, the toxicological significance of its effects remain unknown. Tripartite motif-containing 22 (TRIM22) has been identified as a P4-responsive and apoptosis-related gene. Nevertheless, it has not yet been established whether exogenous chemicals change TRIM22 gene levels. Therefore, the present study investigated the effects of BPA on P4 signaling and TRIM22 and TP53 expression in human breast carcinoma MCF-7 cells. In MCF-7 cells incubated with various concentrations of P4, TRIM22 messenger RNA (mRNA) levels increased in a dose-dependent manner. P4 induced apoptosis and decreased viability in MCF-7 cells. The knockdown of TRIM22 abolished P4-induced decreases in cell viability and P4-induced apoptosis. P4 increased TP53 mRNA expression and p53 knockdown decrease the basal level of TRIM22 and P4 increased TRIM22 mRNA expression independent of p53 expression. BPA attenuated P4-induced increases in the ratio of cell apoptosis in a concentration-dependent manner, and the P4-induced decreases in cell viability was abolished in the presence of 100 nM and higher BPA concentrations. Furthermore, BPA inhibited P4-induced TRIM22 and TP53 expression. In conclusion, BPA inhibited P4-induced apoptosis in MCF-7 cells via the inhibition of P4 receptor transactivation. TRIM22 gene has potential as a biomarker for investigating the disruption of P4 signaling by chemicals.

Abstract
Background Unique cognitive impairments related to chronic obstructive pulmonary diseases (COPD) have been increasingly reported. Considering the dementia risk and medication management, older patients with COPD should be evaluated for cognitive impairment. This study aimed to examine whether specific cognitive impairments related to COPD could be detected by an assessment tool using a touchscreen personal computer (PC) in older patients with COPD. Methods This study included 28 older male patients with COPD and 30 healthy older male individuals. A touchscreen PC-based cognitive assessment application called CogEvo was used to assess and compare the cognitive function according to five domains: spatial cognition, orientation, working memory, executive function, and attention. Results Analysis of variance showed an interaction effect on the indices of cognitive function based on five domains between the two groups, indicating differences in the characteristics of cognitive function in such groups. Betweengroup comparisons as a subtest showed that attention, executive function, and working memory were significantly lower in the COPD group than in the healthy group. Conclusions CogEvo can detect specific cognitive impairments associated with COPD, suggesting that it can be potentially used as a screening tool for cognitive impairment in older patients with COPD.

Abstract
The hepatitis C virus (HCV) causes acute and chronic hepatitis, cirrhosis, and hepatocellular carcinoma, as well as extrahepatic manifestations such as malignant lymphoma. Currently, direct-acting antiviral agents (DAAs) against HCV infection can lead to a sustained virological response (SVR) in almost all HCV-infected patients. In this review article, we discuss acute exacerbation and alanine aminotransferase (ALT) flare in patients with chronic HCV infection. Although acute liver failure caused by HCV infection is rare, careful attention should be paid to the cases with ALT elevation during the natural course of chronic HCV infection. HCV genotype 2 infection, the use of rituximab, and a higher dose of corticosteroid are factors associated with HCV acute exacerbation and ALT flare. Treatment regimens for cancer have been interrupted or changed due to ALT flare due to HCV infection in some patients undergoing chemotherapy for cancer. The pathogenesis of HCV acute exacerbation and ALT flare could involve cellular as well as humoral immune responses. In the DAA era, the earlier introduction of DAAs may prevent chronic HCV-infected patients with acute exacerbation and ALT flare from developing into a more severe form, although DAAs may not be effective for all of them.

Abstract
The development and exacerbation of autoimmune diseases following coronavirus disease 2019 (COVID-19) vaccination have been reported; however, there are few reports of autoimmune hemolytic anemia (AIHA). A 75-year-old woman was admitted to the emergency department 46 days after receiving her third dose of the mRNA-1273 COVID-19 vaccine because of fatigue and general weakness. Initial laboratory analyses revealed severe hemolytic anemia with positive direct and indirect Coombs test and elevation of serum indirect bilirubin and lactate dehydrogenase. The patient had no underlying disease after a close examination and was diagnosed with warm AIHA, which was thought to be associated with COVID-19 vaccination. The anemia improved daily after the administration of prednisolone. Clinicians should be aware of the possibility of AIHA being caused by COVID-19 vaccination, and monotherapy with prednisolone should be considered in cases of severe anemia.

Abstract
OBJECTIVE Heart rate variability (HRV) indicates cardiac autonomic nerve activity and is influenced by brain damage during the neonatal period. We aimed to determine whether a correlation exists between the HRV of extremely preterm neonates and neurodevelopmental test scores. STUDY DESIGN Electrocardiogram data of neonates were assessed and HRV patterns in extremely preterm neonates with severe intraventricular hemorrhage (IVH; n = 6) and those with no/mild IVH (n = 28) were compared. We analyzed the relationship between HRV and neurodevelopmental outcomes at 18 months (n = 21) and 3 years (n = 23) in extremely preterm neonates. RESULTS HRV was significantly associated with IVH severity in extremely preterm neonates (p < 0.05). Neonates with severe IVH exhibited increased HR and decreased mean R-to-R interval (NN) compared with neonates with no/mild IVH. HRV parameters significantly decreased in the severe IVH group, but not in the no/mild IVH group, suggesting that both sympathetic and parasympathetic activities decreased in neonates with severe IVH. Additionally, decreased HR and increased NN were significantly related to impaired neurodevelopmental outcomes in the no/mild IVH group at corrected ages of 18 months and 3 years, respectively (all p < 0.05). CONCLUSION HRV was significantly associated with IVH severity and neurodevelopmental outcome in extremely preterm neonates. HRV can distinguish extremely preterm neonates who subsequently had severe IVH from those who had no/low-grade IVH. HRV may identify extremely preterm neonates needing adjuvant neuroprotective interventions. These findings warrant further investigation in a larger population of extremely preterm neonates. KEY POINTS · HRV was associated with IVH severity.. · HRV can predict subsequent severe IVH in extremely preterm neonates.. · HRV are predictive of neurodevelopmental outcomes in extremely premature neonates with low-grade IVH..

Abstract
Purpose: Although treatment outcomes for childhood cancer have improved in recent years, some patients continue to experience physical symptoms and psychological stress several years after the end of treatment. This study aimed to examine the correlation between the quality-of-life (QOL) scores of childhood cancer survivors (CCSs) aged 18-39 and (1) their families and (2) the time since the end of treatment. Methods: Measuring the QOL of CCSs attending the long-term follow-up (LTFU) and those of their families. The Short-Form Health Survey (SF-36) was used for CCSs and the Caregiver Quality of Life Index-Cancer (CQOLC) for their families. Spearman's rank correlation analyses were used to examine the relationship between the CCSs' and their families' QOL and the time since the end of treatment. Results: Twenty-nine CCSs (mean age, 24.2 years; mean the time since the end of treatment, 13.9 years), each paired with one family member, were included. Time since the end of treatment was positively correlated with the CCSs' QOL on the physical component score (ρ = 0.42, p = 0.03) and negatively correlated with mental health (MH) (ρ = -0.50, p = 0.01), a subscale of the mental component score (MCS). Furthermore, the CCSs' QOL on the MCS was positively correlated with their families' QOL scores (ρ = 0.58, p < 0.01). Conclusion: Psychological stress may persist in CCSs long after treatment, even when physical symptoms improve. Therefore, it is necessary to establish a comprehensive support system for the LTFU of CCSs, including MH care and QOL monitoring for patients and their families.

Abstract
Simple Summary Hepatocellular carcinoma (HCC) is a common malignancy worldwide. The HCC generally develops in the liver of patients already suffering from chronic liver disease. There have been significant advances in both the curative and palliative treatment of HCC. Although liver resection is a curative treatment for HCC, its indication is often limited due to an impaired liver function reservoir. There is still a need to understand how to control liver regeneration after resection and find better cancer immunotherapy and anticancer drugs for advanced HCC. Suppressors of cytokine signaling (SOCS) negatively regulate cytokine signaling related to cell proliferation, differentiation, and immune response; therefore, SOCS are thought to play an important role in HCC development and liver regeneration. Abstract Cytokines are secreted soluble glycoproteins that regulate cellular growth, proliferation, and differentiation. Suppressors of cytokine signaling (SOCS) proteins negatively regulate cytokine signaling and form a classical negative feedback loop in the signaling pathways. There are eight members of the SOCS family. The SOCS proteins are all comprised of a loosely conserved N-terminal domain, a central Src homology 2 (SH2) domain, and a highly conserved SOCS box at the C-terminus. The role of SOCS proteins has been implicated in the regulation of cytokines and growth factors in liver diseases. The SOCS1 and SOCS3 proteins are involved in immune response and inhibit protective interferon signaling in viral hepatitis. A decreased expression of SOCS3 is associated with advanced stage and poor prognosis of patients with hepatocellular carcinoma (HCC). DNA methylations of SOCS1 and SOCS3 are found in HCC. Precise regulation of liver regeneration is influenced by stimulatory and inhibitory factors after partial hepatectomy (PH), in particular, SOCS2 and SOCS3 are induced at an early time point after PH. Evidence supporting the important role of SOCS signaling during liver regeneration also supports a role of SOCS signaling in HCC. Immuno-oncology drugs are now the first-line therapy for advanced HCC. The SOCS can be potential targets for HCC in terms of cell proliferation, cell differentiation, and immune response. In this literature review, we summarize recent findings of the SOCS family proteins related to HCC and liver diseases.

Abstract
We introduce the concept of a handlebody decomposition of a three-manifold, a generalization of a Heegaard splitting, or a trisection. We show that two handlebody decompositions of a closed orientable three-manifold are stably equivalent. As an application to materials science, we consider a mathematical model of polycontinuous patterns and discuss a topological study of microphase separation of a block copolymer melt.

Abstract
Background Renal abscesses are relatively uncommon in children, and usually due to Gram-negative rods or Staphylococcus aureus, whereas abscesses caused by Salmonella are very rare. Case presentation We present the case of a previously healthy 10-year-old boy who had a renal abscess due to Salmonella bareilly. He responded well to treatment with antibiotics, and computed tomography (CT)-guided drainage of the abscess. His blood, urine and abscess aspirate cultures were sterile, but a broad-range 16S rDNA polymerase chain reaction (PCR) assay of the aspirate followed by analysis of four Salmonella genes (fliC, fliD, sopE2, and spaO) identified S. bareilly as the causative agent. Conclusion To the best of our knowledge, this is the first report of renal abscess caused by S. bareilly.

Abstract
BACKGROUND ONO-1301 is a novel long-lasting prostaglandin (PG) I2 mimetic with inhibitory activity on thromboxane (TX) A2 synthase. This drug can also induce endogenous prostaglandin (PG)I2 and PGE2 levels. Furthermore, ONO-1301 acts as a cytokine inducer and can initiate tissue repair in a variety of diseases, such as pulmonary hypertension, pulmonary fibrosis, cardiac infarction, and obstructive nephropathy. In this study, our aim was to evaluate the effect of ONO-1301 on liver inflammation and fibrosis in a mouse model of non-alcoholic steatohepatitis (NASH). METHODS The therapeutic effects of ONO-1301 against liver damage, fibrosis, and occurrence of liver tumors were evaluated using melanocortin 4 receptor-deficient (Mc4r-KO) NASH model mice. The effects of ONO-1301 against macrophages, hepatic stellate cells, and endothelial cells were also evaluated in vitro. RESULTS ONO-1301 ameliorated liver damage and fibrosis progression, was effective regardless of NASH status, and suppressed the occurrence of liver tumors in Mc4r-KO NASH model mice. In the in vitro study, ONO-1301 suppressed LPS-induced inflammatory responses in cultured macrophages, suppressed hepatic stellate cell (HSC) activation, upregulated vascular endothelial growth factor (VEGF) expression in HSCs, and upregulated hepatocyte growth factor (HGF) and VEGF expression in endothelial cells. CONCLUSIONS The results of our study highlight the potential of ONO-1301 to reverse the progression and prevent the occurrence of liver tumors in NASH using in vivo and in vitro models. ONO-1301 is a multidirectional drug that can play a key role in various pathways and can be further analyzed for use as a new drug candidate against NASH.

Abstract
BACKGROUND Few studies have assessed depression in healthcare workers (HCWs) in Japan owing to the coronavirus disease 2019 (COVID-19) pandemic, and no studies have proposed effective interventions to help support their mental health. AIMS To test the hypothesis that enhancing access to mental healthcare professionals helps to improve HCWs' mental health. METHODS This cross-sectional study assessed depressive symptoms in HCWs at three hospitals in Osaka prefecture between May and July, 2020. The survey obtained information on HCWs' mental state and related situations/perceptions. Multivariable logistic regression analysis was performed to identify factors associated with depressive symptoms. RESULTS Of the 3291 eligible HCWs, 1269 (39%) completed the survey. Of all HCWs, 87 (7%) were physicians, and 700 (55%) were nurses. A total of 181 (14%) HCWs had moderate-to-severe symptoms of depression. Being a frontline worker was not significantly associated with depressive symptoms (odds ratio: 0.86 [95% confidence intervals: 0.54-1.37], P = 0.50). The unwillingness to consult with anyone was significantly associated with more severe depressive symptoms (1.70 [1.10-2.63], P < 0.01). HCWs who had no opportunity to confide in family/friends (1.66 [1.10-2.52], P < 0.01) or colleagues/supervisors (3.19 [2.22-4.58], P < 0.001) were significantly more likely to have depressive symptoms. CONCLUSIONS Being a frontline HCW in a Japanese hospital treating patients with COVID-19 was not significantly associated with having depressive symptoms. The study highlights that encouraging daily communication with close persons (family, friends, colleagues and supervisors), rather than improving access to mental health professionals, might help to prevent depression in HCWs during the COVID-19 pandemic.

Abstract
Aspergillus fumigatus causes a range of human and animal diseases collectively known as aspergillosis. A. fumigatus possesses and expresses a range of genetic determinants of virulence, which facilitate colonisation and disease progression, including the secretion of mycotoxins. Gliotoxin (GT) is the best studied A. fumigatus mycotoxin with a wide range of known toxic effects that impair human immune cell function. GT is also highly toxic to A. fumigatus and this fungus has evolved self-protection mechanisms that include (i) the GT efflux pump GliA, (ii) the GT neutralising enzyme GliT, and (iii) the negative regulation of GT biosynthesis by the bis-thiomethyltransferase GtmA. The transcription factor (TF) RglT is the main regulator of GliT and this GT protection mechanism also occurs in the non-GT producing fungus A. nidulans. However, the A. nidulans genome does not encode GtmA and GliA. This work aimed at analysing the transcriptional response to exogenous GT in A. fumigatus and A. nidulans, two distantly related Aspergillus species, and to identify additional components required for GT protection. RNA-sequencing shows a highly different transcriptional response to exogenous GT with the RglT-dependent regulon also significantly differing between A. fumigatus and A. nidulans. However, we were able to observe homologs whose expression pattern was similar in both species (43 RglT-independent and 11 RglT-dependent). Based on this approach, we identified a novel RglT-dependent methyltranferase, MtrA, involved in GT protection. Taking into consideration the occurrence of RglT-independent modulated genes, we screened an A. fumigatus deletion library of 484 transcription factors (TFs) for sensitivity to GT and identified 15 TFs important for GT self-protection. Of these, the TF KojR, which is essential for kojic acid biosynthesis in Aspergillus oryzae, was also essential for virulence and GT biosynthesis in A. fumigatus, and for GT protection in A. fumigatus, A. nidulans, and A. oryzae. KojR regulates rglT, gliT, gliJ expression and sulfur metabolism in Aspergillus species. Together, this study identified conserved components required for GT protection in Aspergillus species. A. fumigatus secretes mycotoxins that are essential for its virulence and pathogenicity. Gliotoxin (GT) is a sulfur-containing mycotoxin, which is known to impair several aspects of the human immune response. GT is also toxic to different fungal species, which have evolved several GT protection strategies. To further decipher these responses, we used transcriptional profiling aiming to compare the response to GT in the GT producer A. fumigatus and the GT non-producer A. nidulans. This analysis allowed us to identify additional genes with a potential role in GT protection. We also identified 15 transcription factors (TFs) encoded in the A. fumigatus genome that are important for conferring resistance to exogenous gliotoxin. One of these TFs, KojR, which is essential for A. oryzae kojic acid production, is also important for virulence in A. fumigatus and GT protection in A. fumigatus, A. nidulans and A. oryzae. KojR regulates the expression of genes important for gliotoxin biosynthesis and protection, and sulfur metabolism. Together, this work identified conserved components required for gliotoxin protection in Aspergillus species.

Abstract
End-of-life discussions are essential for patients with advanced cancer, but there is little evidence about whether these discussions affect general ward patients and family outcomes. We investigated the status of end-of-life discussions and associated factors and their effects on patients' quality of death and their families' mental health. Participants in this retrospective cross-sectional observational study were 119 bereaved family members. Data were collected through a survey that included questions on the timing of end-of-life discussions, quality of palliative care, quality of patient death, and depression and grief felt by the families. Approximately 64% of the bereaved family members participated in end-of-life discussions between the patient and the attending physician, and 55% of these discussions took place within a month before death. End-of-life discussions were associated with the patients' prognostic perception as "incurable, though there is hope for a cure" and "patients' experience with end-of-life discussions with family before cancer." There was a small decrease in depression and grief for families of patients who had end-of-life discussions. Those who did not have end-of-life discussions reported lower quality of end-of-life care.

Abstract
Kojic acid (KA) is a representative secondary metabolite of Aspergillus oryzae, but the underlying molecular mechanisms that regulate KA production are unknown. This study tried to find a genetic factor of KA production in A. oryzae, with a special focus on liquid cultures. We screened a gene predicted to encode HirA, a subunit of the histone chaperon, the HIR complex. A gene disruption strain of hirA showed decreased KA production in liquid culture, whereas it showed increased KA production in plate culture. We confirmed that a decrease/increase of KA production observed by hirA disruption was caused by altered expression of kojA and kojR. These observations suggested the regulatory role of histone chaperon in secondary metabolism in filamentous fungi. So far as we know, this report is the first showing that disruption of a gene resulted in the opposite effect on KA production in liquid and plate cultures in A. oryzae.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) occasionally presents with simultaneous or metachronous primary malignancies of other organs. Despite the limited scope of cytocidal anticancer drugs or molecular targeted agents, immune checkpoint inhibitors (ICIs) can still be used for various malignancies. Here, we present cases of double cancers including HCC treated with ICIs. CASE REPORT Case 1: A 70-year-old man with lung cancer and 80-mm HCC underwent nivolumab therapy. The sizes of both cancers remained constant for nine months. Case 2: A 58-year-old man with pharyngeal cancer and HCC. Nivolumab was administered, but was withdrawn after one session because of progressive disease. Case 3: A 71-year-old man with a 5 cm HCC invading the inferior vena cava, and early esophageal cancer. HCC showed a significant volume reduction and esophageal cancer demonstrated slight improvement by atezolizumab and bevacizumab therapy. CONCLUSION A combination therapy including ICI is a promising treatment option for HCC with concurrent malignancies.

Abstract
A 74-year-old man was diagnosed with hepatocellular carcinoma. The tumor in the liver showed a complete response after transcatheter arterial chemoembolization, but lung, bone, and lymph node metastases were observed, so treatment with atezolizumab plus bevacizumab was initiated. After administration, the scans showed tumor growth, but after continuous administration of atezolizumab plus bevacizumab, the tumors finally reduced in size and showed a partial response. The transient growth of the tumors was considered to be pseudoprogression. Herein, we report a case of pseudoprogression in hepatocellular carcinoma treated with atezolizumab plus bevacizumab.

Abstract
A 57-year-old woman with a sudden-onset seizure was hospitalized. Brain magnetic resonance imaging findings led to a suspicion of leptomeningeal carcinomatosis (LMC) without a brain parenchymal tumor, and abdominal computed tomography showed a tumor in the pancreatic tail. Endoscopic ultrasonography-guided fine needle aspiration of the pancreatic mass revealed adenocarcinoma. Therefore, LMC from pancreatic ductal adenocarcinoma was strongly suspected. She received three courses of nab-paclitaxel plus gemcitabine and whole-brain radiation. Shortly thereafter, she developed a severe consciousness impediment and died. A pathological autopsy showed adenocarcinoma in a wide area of the leptomeninges.

Abstract
A cold-water extract of olive leaves (Olea europaea L.) is useful as a texture-improving agent for food protein gels. In this work, the compound contributing to the improvement of gel properties was investigated by using the egg white gel (EWG) as a model for food protein gels. Adding 1.0% (w/v) cold-water extract (OLEx) greatly improved the elasticity (2.1 times), viscosity (4.5 times), and breaking stress (1.4 times) of the EWG. Chemical analyses of the protein revealed that the enhancement of physical properties by OLEx was attributed to protein cross-linking activity of polyphenols. LC/MS and NMR analyses indicated that a major protein cross-linker is the dialdehydic form of demethoxycarbonylelenolic acid linked to hydroxytyrosol (3,4-DHPEA-EDA), which is an aglycone derived from oleuropein, a major polyphenol of olive leaves. These results suggest that 3,4-DHPEA-EDA generated by cold-water extraction from the leaf improves the physical properties, that is, texture, of protein gels.

Abstract
Objective: The accuracy of rapid on-site evaluation (ROSE) during endobronchial ultrasonography with guide sheath (EBUS-GS) was reported to be approximately 90% for diagnosing small peripheral pulmonary lesions (PPLs). When ROSE during EBUS-GS for diagnosing small peripheral lung cancer is carried out and does not include malignant cells in a position whereby the probe was located within or adjacent to the lesion, the best technique for overcoming the lower diagnostic yield remains unknown. This study aimed to evaluate factors affecting positive results of ROSE during EBUS-GS in such a probe position. Moreover, when the results of ROSE were consistently negative, we evaluated the effectiveness of conventional transbronchial biopsy (TBB) in addition to EBUS-GS alone. Methods: We performed a retrospective analysis of consecutive patients who underwent EBUS-GS combined with ROSE for diagnosing small peripheral lung cancer (≤30 mm). We classified the results of ROSE into two groups based on the presence of malignant cells: the ROSE positive group (included malignant cells) and the ROSE negative group (did not include malignant cells). The significant predictors of positive ROSE results during EBUS-GS were analyzed using multivariate logistic regression analyses. Results: We identified 67 lesions (43 lesions in the ROSE positive group and 24 lesions in the ROSE negative group, respectively). Multivariate logistic analysis revealed that the significant factor affecting positive ROSE results was lesion size (>15 mm) (OR = 9.901). The diagnostic yield of additional conventional TBB to EBUS-GS was significantly higher than that of EBUS-GS alone (75.0% vs 33.3%, P = .041). Conclusion: The positive results of ROSE during EBUS-GS were significantly influenced by lesion size (>15 mm). When the results of ROSE during EBUS-GS were consistently negative in a position whereby the probe was located within or adjacent to the lesion, additional conventional TBB was effective to improve the diagnostic yield compared with EBUS-GS alone.

Abstract
The liver has a high regenerative ability and can induce spontaneous regression of fibrosis when early liver damage occurs; however, these abilities are lost when chronic liver damage results in decompensated cirrhosis. Cell therapies, such as mesenchymal stem cell (MSC) and macrophage therapies, have attracted attention as potential strategies for mitigating liver fibrosis. Here, we evaluated the therapeutic effects of HMGB1 peptide synthesized from box A of high mobility group box 1 protein. Liver damage and fibrosis were evaluated using a carbon tetrachloride (CCl4)-induced cirrhosis mouse model. The effects of HMGB1 peptide against immune cells were evaluated by single-cell RNA-seq using liver tissues, and those against monocytes/macrophages were further evaluated by in vitro analyses. Administration of HMGB1 peptide did not elicit a rapid response within 36 h, but attenuated liver damage after 1 week and suppressed fibrosis after 2 weeks. Fibrosis regression developed over time, despite continuous liver damage, suggesting that administration of this peptide could induce fibrolysis. In vitro analyses could not confirm a direct effect of HMGB1 peptide against monocyte/macrophages. However, macrophages were the most affected immune cells in the liver, and the number of scar-associated macrophages (Trem2+Cd9+ cells) with anti-inflammatory markers increased in the liver following HMGB1 treatment, suggesting that indirect effects of monocytes/macrophages were important for therapeutic efficacy. Overall, we established a new concept for cell-free therapy using HMGB1 peptide for cirrhosis through the induction of anti-inflammatory macrophages.

Abstract
PURPOSE Diagnosis of liver fibrosis is important for establishing treatment and assessing the risk of carcinogenesis. Ultrasound imaging is an excellent diagnostic method as a screening test in terms of non-invasiveness and simplicity. The purpose of this study was to automatically diagnose liver fibrosis using ultrasound images to reduce the burden on physicians. METHODS We proposed and implemented a system for extracting regions of liver parenchyma utilizing U-Net. Using regions of interest, the stage of fibrosis was classified as F0, F1, F2, F3, or F4 utilizing CORALNet, an ordinal regression model based on ResNet18. The effectiveness of the proposed system was verified. RESULTS The system implemented using U-Net had a maximum mean Dice coefficient of 0.929. The results of classification of liver fibrosis utilizing CORALNet had a mean absolute error (MAE) of 1.22 and root mean square error (RMSE) of 1.60. The per-case results had a MAE of 1.55 and RMSE of 1.34. CONCLUSION U-Net extracted regions of liver parenchyma from the images with high accuracy, and CORALNet showed effectiveness using ordinal information to classify fibrosis in the images. As a future task, we will study a model that is less dependent on teaching data.

Abstract
The number of patients with non-alcoholic steatohepatitis (NASH) and inflammatory bowel disease (IBD) is increasing. This study elucidates the effect of both NASH and IBD on hepatocellular carcinoma (HCC) using a mouse model combining NASH and IBD. The melanocortin 4 receptor-deficient (Mc4r-KO) mice were divided into four groups with or without a high-fat diet (HFD) and with or without dextran sulfate sodium (DSS) to induce colitis, and the differences in liver damage and occurrence of HCC were analyzed. In the HFD + DSS group, the body weight, liver weight/body weight ratio, and serum levels of albumin and alanine aminotransferase were significantly lower than those in the HFD group. We further found that steatosis was significantly lower and lobular inflammation was significantly higher in the HFD + DSS group than those in the HFD group, and that individual steatosis and lobular inflammation state in the HFD + DSS mice varied. We detected HCC only in the HFD + DSS group, and mice with severe steatosis and mild colitis were found to be at high risk of HCC. Presently, the prediction of HCC is very difficult. In some cases, severe colitis reverses the fat accumulation due to appetite loss. Our findings clearly showed that severe steatohepatitis and mild colitis are simultaneously essential for the occurrence of HCC in patients with NASH and IBD.

Abstract
Background Liver cirrhosis is an end-stage multiple liver disease. Mesenchymal stem cells (MSCs) are an attractive cell source for reducing liver damage and regressing fibrosis; additional therapies accompanying MSCs can potentially enhance their therapeutic effects. Kampo medicines exhibit anti-inflammatory and anti-oxidative effects. Here, we investigated the therapeutic effect of MSCs combined with the Kampo medicine Juzentaihoto (JTT) as a combination therapy in a carbon tetrachloride (CCl4)-induced cirrhosis mouse model. Methods C57BL/6 mice were administered JTT (orally) and/or MSCs (one time, intravenously). The levels of liver proteins were measured in the sera. Sirius Red staining and hydroxyproline quantitation of hepatic tissues and immune cells were conducted, and their associated properties were evaluated. Liver metabolomics of liver tissues was performed. Results JTT monotherapy attenuated liver damage and increased serum albumin level, but it did not effectively induce fibrolysis. JTT rapidly reduced liver damage, in a dose-dependent manner, after a single-dose CCl4 administration. Furthermore, JTT-MSC combination therapy attenuated liver damage, improved liver function, and regressed liver fibrosis. The combination increased the CD4+/CD8+ ratio. JTT had stronger effects on NK and regulatory T cell induction, whereas MSCs more strongly induced anti-inflammatory macrophages. The combination therapy further induced anti-inflammatory macrophages. JTT normalized lipid mediators, and tricarboxylic acid cycle- and urea cycle-related mediators effectively. Conclusions The addition of JTT enhanced the therapeutic effects of MSCs; this combination could be a potential treatment option for cirrhosis. Juzentaihoto (JTT) enhanced the therapeutic effects of mesenchymal stem cells (MSCs). JTT induced NK and regulatory T cells, whereas MSCs induced anti-inflammatory macrophages. JTT normalized lipid mediators, the tricarboxylic acid cycle, and urea cycle-related mediators. This combination could be a potential treatment option against cirrhosis therapy.

Abstract
BACKGROUND An implantable cardioverter defibrillator (ICD) is the most reliable therapeutic device for preventing sudden cardiac death in patients with sustained ventricular tachycardia (VT). Regarding its effectiveness, targeted VT is defined based on the tachyarrhythmia cycle length. However, variations in RR interval variability of VTs may occur. Few studies have reported on VT characteristics and effects of ICD therapy according to the RR interval variability. We aimed to identify the clinical characteristics of VTs and ICD therapy effects according to the RR interval variability. METHODS We analyzed 821 VT episodes in 69 patients with ICDs or cardiac resynchronization therapy defibrillators. VTs were classified as irregular when the difference between two successive beats was >20 ms in at least one of 10 RR intervals; otherwise, they were classified as regular. We evaluated successful termination using anti-tachycardia pacing (ATP)/shock therapy, spontaneous termination, and acceleration between regular and irregular VTs. The RR interval variability reproducibility rates were evaluated. RESULTS Regular VT was significantly more successfully terminated than irregular VT by ATP. No significant difference was found in shock therapy or VT acceleration between the regular and irregular VTs. Spontaneous termination occurred significantly more often in irregular than in regular VT cases. The reproducibility rates of RR interval variability in each episode and in all episodes were 89% and 73%, respectively. CONCLUSIONS ATP therapy showed greater effectiveness for regular than for irregular VT. Spontaneous termination was more common in irregular than in regular VT. RR interval variability of VTs seems to be reproducible.

Abstract
PURPOSE Fibrosis is a predictor of mortality in patients with non-alcoholic fatty liver disease (NAFLD). In our institution, abdominal ultrasonography has been performed based on a unified method consisting of 25 images. We investigated ultrasonographic grayscale findings related to fibrosis in patients with NAFLD. METHODS This retrospective study comprised 41 cases of pathologically proven fatty liver between January 2015 and September 2020. A total of 26 ultrasonographic findings were subjectively evaluated. These findings, transient elastography (TE) with M probe, and FIB-4 index were compared with fibrosis stage. RESULTS The frequency of roughness of the dorsal side of the surface (p < 0.001), heterogenicity of the parenchyma (p = 0.003), narrowing of the hepatic vein (p = 0.004), and splenomegaly (p < 0.001) were strongly correlated with the fibrosis stage. Logistic regression analysis for stage ≥ 3 showed narrowing of the hepatic vein (odds ratio [OR] 5.860, p = 0.031) and splenomegaly (OR 6.290, p = 0.028). Logistic regression analysis for stage 4 showed roughness of the ventral side of the surface (OR 42.0, p = 0.019). The AUROC for stage 3 and stage 4 with the number of positive ultrasonographic findings was 0.856, and 0.940, respectively. The AUROC for F3 and F4 with TE was 0.831 and 0.861, respectively. The AUROC for stage 3 and stage 4 with FIB-4 index was 0.815 and 0.806, respectively. CONCLUSIONS Narrowing of the hepatic vein, roughness of the dorsal side of the surface, heterogenicity of the parenchyma, and splenomegaly and their combination could predict fibrosis in patients with NAFLD.

Abstract
PURPOSE Hemodynamic change after total paracentesis was investigated because it might lead to various complications. Although cell-free and concentrated ascites reinfusion therapy (CART) is safer and more effective than total paracentesis in theory, hemodynamic change after CART has been never reported. And previous studies did not mention hemodynamics of the venous system. METHODS We investigated the hemodynamic change, including that of the venous system, before and after CART using color Doppler ultrasonography and fast Fourier transform analysis. Twenty-eight patients with tensive cirrhotic ascites underwent ultrasonography the day before and after total volume CART. The diameter and velocity of the main, right, and left portal vein; inferior vena cava (IVC); and right renal vein were measured using ultrasonography. RESULTS A total of 11.8 ± 4.4 L of ascites (range 3.6-20.9 L) was filtered and concentrated to 0.85 ± 0.40 L (range 0.36-1.50 L). The diameter of the IVC increased from median 13.5 ± 5.4 mm (range 4-25 mm) to 18.5 ± 4.1 mm (range 7-29 mm) (p = 0.007). The diameter of the right segmental renal vein significantly increased after KM-CART [from 5.0 ± 1.0 (4-8) mm to 7.0 ± 2.0 (3-10) mm] (p = 0.011). Hemodynamic change of the portal venous system was not significant. The time to the next CART in patients with an IVC diameter ≥ 20 mm and < 20 mm was 86 days and 20.5 days (p = 0.035), respectively. CONCLUSION Tensive ascites results in venous congestion in patients with cirrhotic ascites. CART improved venous flow, but it did not change the hemodynamics of the portal venous system.

Abstract
Koji molds, such as Aspergillus oryzae and Aspergillus sojae, are used in the food industry in East Asia and have been explored for the large-scale production of extracellular hydrolases. We previously found that the deletion of a gene encoding a putative GT2 glycosyltransferase increased production of extracellular hydrolases in A. sojae. The gene was named rseA (regulator of the secretory enzyme A). We predicted that intracellular signaling pathways were involved in the increased production of hydrolases in the ΔrseA mutant of A. sojae. However, little has been reported on molecular biological knowledge about A. sojae. Hence, Aspergillus nidulans, a typical model organism used in molecular biology, was employed for the functional characterization of rseA in this study. Deletion of the rseA ortholog in A. nidulans induced increased extracellular production of hydrolases under the solid-state cultivation condition, similar to that in A. sojae. The involvement of the cell wall integrity pathway and the high osmolarity glycerol pathway in ΔrseA was further investigated. The results indicated that the HOG pathway played an important role in the increased extracellular production of hydrolases caused by the deletion of the rseA gene. rseA ortholog in A. nidulans was identical to cpsA, which was reported to function as a regulator of mycotoxin production, morphogenesis, and cell wall biosynthesis. However, this is the first study reporting that rseA/cpsA regulates extracellular hydrolase production in A. nidulans.

Abstract
OBJECTIVES Quantitative image analysis is one of the methods to overcome the lack of objectivity of ultrasound (US). The aim of this study was to clarify the correlation between the features from a US image analysis and the histologic grade and microvascular invasion (MVI) of hepatocellular carcinoma (HCC) and differentiation of HCC smaller than 2 cm from borderline lesions. METHODS We retrospectively analyzed grayscale US images with histopathologic evidence of HCC or a precancerous lesion using ImageJ version 1.47 software (National Institutes of Health, Bethesda, MD). RESULTS A total of 148 nodules were included (borderline lesion, n = 31; early HCC [eHCC], n = 3; well-differentiated HCC [wHCC], n = 16; moderately differentiated HCC [mHCC], n = 79; and poorly differentiated HCC [pHCC], n = 19). A multivariate analysis selected lower minimum gray values (odds ratio [OR], 0.431; P = .003) and a higher standard deviation (OR, 1.880; P = .019) as predictors of HCC smaller than 2 cm. Median (range) minimum gray values of borderline lesions, eHCC, wHCC, mHCC, and pHCC were 29 (0-103), 7 (0-47), 6 (0-60), 10 (0-53), and 2 (0-38), respectively, and gradually decreased from borderline lesions to pHCC (P < 0.001). The multivariate analysis showed a higher aspect ratio (OR, 2.170; P = .001) and lower minimum gray value (OR, 0.475; P = .043) as predictors of MVI. An anechoic area diagnosed by a subjective evaluation was correlated with the minimum gray value (P < .0001). The proportion of the anechoic area gradually increased from eHCC to pHCC (P = .031). CONCLUSIONS In a US image analysis, HCC smaller than 2 cm had features of greater heterogeneity and a lower minimum gray value than borderline lesions. Moderately differentiated HCC was smoother than borderline lesions, and the anechoic area correlated with histologic grading. Microvascular invasion was correlated with a slender shape and a lower minimum gray value.

Abstract
Young adult survivors of childhood cancer may have a perception gap with their families. Patients aged 18-39 years after treatment of cancer and their families (28 pairs) completed a survey that contained questions on health-related quality of life using the 36-item short form survey. There was a significant difference in the role-social component score (mean difference -2.23; p = 0.04) with family reporting higher scores than patients. Families may overestimate the social function of cancer survivors, emphasizing the importance of the long-term follow-up by taking into account the risk of a gap (IRB approval No.: R2257-1).

Abstract
AIM To clarify the utility of contrast-enhanced ultrasonography (CEUS) for interim evaluation of response to chemotherapy in lymphoma treatment. MATERIALS AND METHODS CEUS was performed both before (day 0) and after the treatment (7 and/or 14 days), and a time-intensity curve was obtained. The patients were divided into two groups (complete remission [CR] group and non-CR group) according to the results of conventional response evaluation, and peak enhancement (PE), time to peak enhancement, perfusion index (PI), the total area under the curve during wash-in (AUC-in), and the total AUC were compared between the groups. RESULTS Among 27 patients with various types of lymphoma, the median change ratio of PE and PI at day 7 evaluation were significantly different between the CR group and the non-CR group (0.81 versus 1.39, p=0.017 for PE and 0.92 versus 2.09, p=0.010 for PI). The change ratio of PE < 1.09 (specificity: 86%; sensitivity, 88%) and PI < 1.65 (specificity: 86%; sensitivity: 94%) distinguished CR from non-CR. Patients who achieved a PE change ratio <1.09 or a PI change ratio <1.65 had significantly better estimated progression-free survival (p<0.001). CONCLUSION The present study demonstrated that changes in tumour perfusion parameters evaluated with CEUS at 1 week after the treatment initiation were significantly different between lymphoma patients in CR group and non-CR group. Alterations in perfusion parameters evaluated via CEUS could impact the prognosis of lymphoma patients.
