A Newly Developed Method-Based Xanthine Oxidoreductase Activities in Various Human Liver Diseases. Biomedicines 2023; 11:biomedicines11051445. [PMID: 37239117 DOI: 10.3390/biomedicines11051445] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 05/03/2023] [Accepted: 05/08/2023] [Indexed: 05/28/2023] Open
Abstract
Studies evaluating xanthine oxidoreductase (XOR) activities in comprehensive liver diseases are scarce, and different etiologies have previously been combined in groups for comparison. To accurately evaluate XOR activities in liver diseases, the plasma XOR activities in etiology-based comprehensive liver diseases were measured using a novel, sensitive, and accurate assay that is a combination of liquid chromatography and triple quadrupole mass spectrometry to detect [13C2, 15N2]uric acid using [13C2, 15N2]xanthine as a substrate. We also mainly evaluated the association between the plasma XOR activities and parameters of liver tests, purine metabolism-associated markers, oxidative stress markers, and an inflammation marker. In total, 329 patients and 32 controls were enrolled in our study. Plasma XOR activities were generally increased in liver diseases, especially in the active phase, such as in patients with hepatitis C virus RNA positivity, those with abnormal alanine transaminase (ALT) levels in autoimmune liver diseases, and uncured hepatocellular carcinoma patients. Plasma XOR activities were numerically highest in patients with acute hepatitis B. Plasma XOR activities were closely correlated with parameters of liver tests, especially serum ALT levels, regardless of etiology and plasma xanthine levels. Our results indicated that plasma XOR activity might reflect the active phase in various liver diseases.

Probing Gluon Spin-Momentum Correlations in Transversely Polarized Protons through Midrapidity Isolated Direct Photons in p^{↑}+p Collisions at sqrt[s]=200 GeV. PHYSICAL REVIEW LETTERS 2021; 127:162001. [PMID: 34723614 DOI: 10.1103/physrevlett.127.162001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 07/26/2021] [Accepted: 08/10/2021] [Indexed: 06/13/2023]
Abstract
Studying spin-momentum correlations in hadronic collisions offers a glimpse into a three-dimensional picture of proton structure. The transverse single-spin asymmetry for midrapidity isolated direct photons in p^{↑}+p collisions at sqrt[s]=200 GeV is measured with the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). Because direct photons in particular are produced from the hard scattering and do not interact via the strong force, this measurement is a clean probe of initial-state spin-momentum correlations inside the proton and is in particular sensitive to gluon interference effects within the proton. This is the first time direct photons have been used as a probe of spin-momentum correlations at RHIC. The uncertainties on the results are a 50-fold improvement with respect to those of the one prior measurement for the same observable, from the Fermilab E704 experiment. These results constrain gluon spin-momentum correlations in transversely polarized protons.

Lenvatinib for Hepatocellular Carcinoma Patients with Nonviral Infection Who Were Unlikely to Respond to Immunotherapy: A Retrospective, Comparative Study. Oncology 2021; 99:641-651. [PMID: 34515171 DOI: 10.1159/000517494] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 05/28/2021] [Indexed: 11/19/2022]
Abstract
AIM Atezolizumab plus bevacizumab (atezo + bev) shows a good overall survival (OS) in advanced hepatocellular carcinoma (HCC) patients. However, the OS of patients with nonviral infection is quite worse than that in those with viral infection. The present study investigated the efficacy and safety of lenvatinib in patients with nonviral infection, who were unlikely to obtain benefit from atezo + bev. METHODS We conducted a multicenter retrospective study that included 139 advanced HCC patients treated with lenvatinib between March 2018 and September 2020. RESULTS The median age was 72 years, and 116 patients (83.5%) were male. Based on the etiology of liver disease, 84 (60.4%) and 55 patients (39.6%) were assigned to the viral infection and nonviral infection groups, respectively. The significant extents in patient characteristics were not observed in both groups. The objective response rate per mRECIST and progression-free survival (PFS) did not differ significantly between the viral infection and nonviral infection groups (36.0 vs. 33.0%, p = 0.85; and 7.6 vs. 7.5 months, p = 0.94, respectively). The 1-year survival rates were 68.7% (95% confidence interval [CI] 57.7-79.7%) in the viral infection group and 59.5% (95% CI 45.2-73.8%) in the nonviral infection group. The viral infection group was not a significant factor associated with the PFS or OS in a multivariate analysis. CONCLUSIONS Lenvatinib shows no significant difference in response between patients with and without viral infection. Treatment strategies based on the etiology of liver disease may lead to good clinical outcome.

Therapeutic efficacy of lenvatinib as third-line treatment after regorafenib for unresectable hepatocellular carcinoma progression. Hepatol Res 2021; 51:880-889. [PMID: 33837620 DOI: 10.1111/hepr.13644] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 01/25/2021] [Accepted: 04/01/2021] [Indexed: 02/05/2023]
Abstract
AIM Multiple molecular agents have been developed for treating unresectable hepatocellular carcinoma. This study aimed to elucidate the clinical efficacy of sequential treatment with lenvatinib after regorafenib failure. METHODS From June 2017 to October 2020, 63 patients with Child-Pugh A and treated with regorafenib followed by sorafenib were enrolled (median age 71 years, 52 men, Barcelona Clinic Liver Cancer B:C = 23:40). They were divided into two groups, those treated with lenvatinib after regorafenib treatment (R-L group, n = 47) and those who did not receive lenvatinib after regorafenib (non-R-L group, n = 16). Prognostic factors were retrospectively analyzed after adjustment with inverse probability weighting. RESULTS Serum albumin level at the start of regorafenib and reasons for discontinuation of regorafenib were significantly different between the R-L and non-R-L groups, whereas the albumin-bilirubin score, Child-Pugh class, and tumor burden were not. Progression-free survival was also not significantly different (median 4.1 vs. 3.8 months, p = 0.586). As for overall survival, the R-L group showed better prognosis after introducing regorafenib and after introducing sorafenib, following inverse probability weighting adjustment (MST 19.7 vs. 10.3 months, 33.8 vs. 15.3 months, p < 0.001 and p = 0.022, respectively). Modified albumin-bilirubin grade 2b (score >-2.27) at the start of regorafenib (HR 2.074, p = 0.041) and the presence of lenvatinib treatment after regorafenib failure (HR 0.355, p = 0.004) were found to be significant prognostic factors in Cox proportional hazards multivariate analysis, after inverse probability weighting adjustment. CONCLUSION These results show that lenvatinib is a good sequential treatment option after progression under regorafenib therapy in unresectable hepatocellular carcinoma patients with better hepatic reserve function.

Abstract
Objective Chronic hepatitis C virus (HCV) infection carries a residual risk of hepatocarcinogenesis even after viral elimination, so appropriate follow-up is necessary. The present study investigated the current hospital visits and hepatocarcinogenesis status of patients who received daclatasvir plus asunaprevir treatment (DCV+ASV) to determine whether or not appropriate follow-up was being performed. Methods We retrospectively analyzed hepatocarcinogenesis, the overall survival, and the length of hospital visits in 442 patients who applied for the medical expense subsidy system for viral hepatitis and received DCV+ASV treatment in Gunma Prefecture between October 2014 and December 2015. This also included 61 patients who had a history of hepatocellular carcinoma (HCC). Results Among 442 patients, 388 achieved a sustained viral response (SVR) by DCV+ASV therapy (87.8%), and 95.9% achieved an SVR if additional treatment was included. HCC was found in 75 cases (17.0%). A history of HCC, the FIB-4 index and the treatment effect SVR were determined to be factors affecting the incidence of HCC. Regarding the follow-up rate, 89.9% of patients continued to regularly visit the hospital after 5 years of treatment. However, patients ≤60 years old had significantly lower persistence rates than older patients. The persistence rate of hospital visits to the same institution was 67.7% over a 5-year period, which was significantly better in small and medium-sized institutions than in large, specialized institutions (71.7% vs. 63.9%, p=0.039). Conclusion Patients with direct-acting antiviral treatment generally received adequate follow-up, but younger patients had a slightly higher rate of follow-up interruption and were considered to need support.

Abstract
AIM The aim of this retrospective study was to investigate the efficacy and safety of ramucirumab treatment under real-world conditions and to clarify the role of albumin-bilirubin (ALBI) score in predicting outcomes. METHODS Between June 2019 and May 2020, a total of 16 patients with advanced hepatocellular carcinoma (HCC) treated with ramucirumab in Gunma Saiseikai Maebashi Hospital and its affiliated hospitals was included. RESULTS The median age was 71 (interquartile range [IQR] 65-74) years old, and 12 patients (75.0%) were male. The modified ALBI (mALBI) grade was 1, 2a, and 2b at baseline in 4 (25.0%), 3 (18.8%), and 9 patients (56.3%), respectively. The Barcelona Clinic Liver Cancer stage was intermediate and advanced stage in 1 (6.3%) and 15 patients (93.8%), respectively. The serum α-fetoprotein at baseline was 4,911 (IQR 2,091-17,377) ng/mL. The disease control rate in patients with mALBI grade1 + 2a was significantly higher than in those with mALBI grade 2b (100 vs. 28.6%, p = 0.028). The patients with mALBI grade 1 + 2a had a significantly better overall survival (OS) and longer progression-free survival (PFS) than those with mALBI grade 2b (median OS 6.7 vs. 3.0 months; p = 0.036, median PFS 7.5 vs. 1.4 months; p = 0.002). The number of cycles of ramucirumab treatment was significantly correlated with the ALBI score (r = -0.452, p = 0.030). The patients with mALBI grade 1 + 2a showed a low incidence of adverse events (AEs) and discontinuation due to AEs. CONCLUSIONS Advanced HCC patients with mALBI grade 1 + 2a may be a good indication for ramucirumab treatment.

Liver Function Changes in Patients with Hepatocellular Carcinoma Treated with Lenvatinib: Predictive Factors of Progression to Child-Pugh Class B, the Formation of Ascites and the Candidates for the Post-Progression Treatment. Cancers (Basel) 2020; 12:cancers12102906. [PMID: 33050527 PMCID: PMC7601832 DOI: 10.3390/cancers12102906] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Revised: 09/26/2020] [Accepted: 10/07/2020] [Indexed: 02/08/2023] Open
Abstract
The aim of this multicenter retrospective study was to assess the change in liver function in patients with hepatocellular carcinoma treated with lenvatinib. Among 139 consecutive patients receiving lenvatinib treatment between March 2018 and July 2019, 28 patients with Child-Pugh class B and one patient with inadequate patient information were excluded. Remaining 110 patients with Child-Pugh class A were analyzed. The median age of 110 patients was 73 years (IQR 66.7-80) and 88 patients (80.0%) were men. Child-Pugh score was 5 (CP5A) and 6 (CP6A) in 58 (52.7%) and 52 patients (47.3%), and ALBI grade was 1 and 2 in 38 (34.5%) and 72 patients (65.5%), respectively. The deterioration to Child-Pugh class B was found in 43 patients (39.1%) during the lenvatinib treatment. The favorable factors related to preserving liver function were significantly shown to be male, ALBI grade 1, CP5A and BCLC early or intermediate stage in the multivariate analysis. The formation of ascites was found in 32 patients (28.6%). The significant unfavorable factors associated with the formation of ascites were found to be low platelet count and CP6A. Among the 79 patients, there were 36 (45.6%) and 11 patients (13.9%) who fulfilled the criteria for candidate for the post-progression treatment and ramucirumab treatment, respectively. The predictive factors of the post-progression treatment were shown to be ALBI grade 1 and CP5A in multivariate analysis. In conclusion, male, ALBI grade 1, CP5A and BCLC early or intermediate stage were favorable factors related to sustaining liver function and the patients with ALBI grade 1 and CP5A were eligible for the post-progression treatment. Careful screening for ascites was needed in patients with low platelet count and CP6A.

Abstract
Background:Biologic disease modifying anti-rheumatic drugs (DMARDs) have demonstrated that proinflammatory cytokines such as interleukin (IL-) 6 and tumor necrosis factor (TNF) play important roles in the pathogenesis of rheumatoid arthritis (RA). Other cytokines, such as type I interferons (IFNs), are also implicated in its pathogenesis (ref 1). However, the complete picture of the cytokine network involved in RA remains to be elucidated.Objectives:By quantifying sets of cytokines in the serum of RA patients before and after treatment with various biologic DMARDs, we sought to determine the effects of drugs on (A) type I IFNs, (B) soluble IL-6 receptors, and (C) other cytokines.Methods:52 patients with RA were treated with various biologic DMARDs (tocilizumab (TOC): 16, abatacept (ABT): 15, and TNF inhibitors (TNFi): 21). Serum samples were obtained (1) before, (2) approximately 4 weeks after (3) and approximately 12 weeks after the initiation of treatment. A suspension bead-array system was used for analysis; Bio-Plex Human Cytokine 17-plex Assay kits and Express Custom Panels (Bio-Rad), including IFN-β, IFN-α2, soluble IL-6 receptor α (sIL6Rα) and gp130 were used.Results:(1) As expected, the disease activity score 28-joiny count (DAS28) using the erythrocyte sedimentation rate (ESR) significantly decreased in all three groups (TOC, ABT and TNFi) by 12 weeks.(2) IFN-α2 was barely detected in the serum samples. IFN-β seemed to increase slightly in the ABT group, but the increase was not statistically significant.(3) The levels of sIL6Rα did not change substantially. Those of gp130 decreased slightly but significantly in the TOC group by 12 weeks.(4) The levels of IL-6 decreased significantly in the ABT group by 12 weeks. Those in the TNFi group decreased significantly at 4 weeks but not 12 weeks (Fig. 1A).(5) The levels of IL-7 decreased significantly only in the TOC group (Fig. 1B).Conclusion:(1) The biologic DMARDs tested in this study did not significantly affect the serum levels of type I IFNs in this study.(2) The decrease in gp130 in the TOC group may imply that gp130 is induced by IL-6, although whether this level of decrease has physiological significance is open to question.(3) Serum IL-6 was significantly decreased in the TNFi group at 4 weeks but not 12 weeks. TNF has been reported to induce IL-6 (ref 2), but negative feedback loop(s) may be present. Such a feedback system might make the discontinuation of TNFi difficult, even if patients are in remission.(4) IL-7 may be a target of IL-6. A higher level of IL-7 has been reported to be present in the joints of RA patients compared with osteoarthrosis and it is a cytokine implicated in the differentiation of osteoclasts (ref 3). This may partly explain the effect of TOC on preventing bone erosion in RA.References:[1]Ann Rheum Dis. 2007; 66: 1008–14[2]Rheumatology 2007; 46: 920-6[3]Rheumatology 2008; 47: 753-9Acknowledgments:We thank all the members of the Division of Rheumatology and Clinical Immunology, Department of Medicine, Jichi Medical University.

Abstract
AIM The aim of this study was to investigate the predictive factors of objective response rate (ORR) and progression-free survival (PFS), and the correlation of albumin-bilirubin (ALBI) grade with decreased appetite and fatigue in hepatocellular carcinoma patients treated with lenvatinib. METHODS From March 2018 to December 2018, a total of 94 patients was included in this retrospective multicenter study. RESULTS The median age of all patients was 73 years (interquartile range 66-79.3 years), and approximately 78% patients were men. The ALBI grade was 1, 2, and 3 in 27 (28.7%), 64 (68.1%), and three patients (3.2%), respectively. The Barcelona Clinic Liver Cancer stage was early, intermediate, and advanced in one (1.1%), 22 (23.4%), and 71 patients (75.5%), respectively. Best radiological response was determined to complete response, partial response, stable disease, and progressive disease in 0 (0.0%), 24 (30.4%), 38 (48.1%), and 17 patients (21.5%), respectively, giving the ORR of 30.4%. The 3-, 6-, and 12-month PFS was calculated to be 78.7% (95% CI 70.3-87.1%), 46.7% (95% CI 36.1-57.3%), and 17.4% (95% CI 6.6-28.2%). Multivariate analysis showed that the Barcelona Clinic Liver Cancer intermediate stage was shown to be the only significant factor affecting the ORR (odds ratio 3.78, 95% CI 1.14-12.5, P = 0.030) and PFS (hazard ratio 0.49, 95% CI 0.26-0.94, P = 0.030). The incidence of all grades of decreased appetite and fatigue was significantly less in patients with ALBI grade 1 compared with ALBI grade 2 + 3. CONCLUSIONS The Barcelona Clinic Liver Cancer intermediate stage was the predictive factor affecting the ORR and PFS, and ALBI grade was a good predictive factor affecting the incidence of fatigue and decreased appetite.

Abstract
AIM In patients with hepatitis C virus, treatment failure of daclatasvir plus asunaprevir combination therapy (DCV + ASV) seems to become intractable due to the induction of resistance-associated substitutions. This study aimed to investigate the outcomes of retreatment with direct-acting antivirals (DAAs) in patients with DCV + ASV therapy failure, as well as changes in drug resistance mutations. METHODS We retrospectively analyzed 44 patients re-treated with DAAs after DCV + ASV failure between December 2015 and April 2018. All patients were analyzed for amino acid substitutions, and additional treatment regimens were selected based on the results and current treatment guidelines. RESULTS The sustained virological response rate with second-line treatment was 81.8% (36/44), and relapse occurred in five of 16 patients who received sofosbuvir/ledipasvir and three of seven patients who received DCV/ASV/beclabuvir. Third- and fourth-line treatments were also tried in relapsed cases, and the overall sustained virological response rates were 90.9% (40/44) and 93.2% (41/44), respectively. A high rate of viral clearance was eventually observed. Before second-line treatment, the prevalence of mutations in the NS5A and NS3/4A regions was 100% (44/44) and 86.4% (38/44), respectively. There was no significant increase in the number of amino acid substitutions in patients for whom second-line treatment failed. CONCLUSIONS Amino acid substitutions were frequently observed in patients with DCV + ASV failure, but most patients achieved a sustained virological response after retreatment with DAAs. Although the spread of drug-resistant viruses due to unsuccessful DAA treatment was a matter of concern, most cases of DCV + ASV failure were overcome with additional treatment.

Abstract
We report on the nuclear dependence of transverse single-spin asymmetries (TSSAs) in the production of positively charged hadrons in polarized p^{↑}+p, p^{↑}+Al, and p^{↑}+Au collisions at sqrt[s_{NN}]=200 GeV. The measurements have been performed at forward rapidity (1.4<η<2.4) over the range of transverse momentum (1.8<p_{T}<7.0 GeV/c) and Feynman x (0.1<x_{F}<0.2). We observed positive asymmetries for positively charged hadrons in p^{↑}+p collisions, and significantly reduced asymmetries in p^{↑}+A collisions. These results reveal a nuclear dependence of TSSAs for charged-hadron production in a regime where perturbative techniques are applicable. These results provide new opportunities to use p^{↑}+A collisions as a tool to investigate the rich phenomena behind TSSAs in hadronic collisions and to use TSSAs as a new handle in studying small-system collisions.

Abstract
Objective The purpose of this multicenter retrospective study was to investigate the impact of the prognostic nutritional index (PNI) on the survival of Japanese patients with hepatocellular carcinoma (HCC) treated with sorafenib. Methods A total of 178 HCC patients from May 2009 to December 2015 at our affiliated hospitals was included in this study. The PNI was calculated as follows: 10×serum albumin (g/dL) +0.005×total lymphocyte count (per mm3). The patients were divided into two groups according to the cut-off value of the PNI and as calculated by a receiver operating characteristic curve analysis. Results The optimum cut-off value of the PNI was set at 46.8. We defined the 33 patients with a PNI≥46.8 as the PNI-high group and the 145 patients with a PNI<46.8 as the PNI-low group. The response rate was 20.0% in the PNI-high group and 8.1% in the PNI-low group, without any statistically significance (p=0.09). The duration of sorafenib therapy and the overall survival in the PNI-high group were significantly better than those in the PNI-low group. The PNI-high group was thus found to be a predictive factor associated with the duration of sorafenib therapy [hazard ratio (HR) 0.58; 95% confidence interval (CI) 0.39-0.87, p=0.008] and overall survival (HR 0.62; 95% CI 0.39-0.99, p=0.046) in a multivariate analysis. Conclusion The PNI is a simple and useful marker for predicting the survival of patients with HCC treated with sorafenib.

Abstract
Asymmetric nuclear collisions of p+Al, p+Au, d+Au, and ^{3}He+Au at sqrt[s_{NN}]=200 GeV provide an excellent laboratory for understanding particle production, as well as exploring interactions among these particles after their initial creation in the collision. We present measurements of charged hadron production dN_{ch}/dη in all such collision systems over a broad pseudorapidity range and as a function of collision multiplicity. A simple wounded quark model is remarkably successful at describing the full data set. We also measure the elliptic flow v_{2} over a similarly broad pseudorapidity range. These measurements provide key constraints on models of particle emission and their translation into flow.

Abstract
This study was performed to investigate the clinical characteristics of lupus enteritis in Japanese patients with systemic lupus erythematosus (SLE). A total of 481 patients with SLE admitted to our hospital between 2001 and 2015 were retrospectively reviewed. Diagnosis of lupus enteritis was based on the following three criteria: (1) abdominal symptoms, (2) diffuse long-segment bowel thickening and (3) a requirement for glucocorticoid therapy. Lupus enteritis was identified in 17 patients (3.5%) and there were two distinct types: small intestine-dominant and large intestine-dominant. Significant differences between the two types were noted with respect to the age, frequency of biopsy-proven lupus nephritis, frequency of rectal involvement, maximum bowel wall thickness, and requirement for steroid pulse therapy. Among patients with large intestine-dominant lupus enteritis, 60% had extra-intestinal symptoms (hydroureter, bladder wall thickening, and bile duct dilatation) that are known complications of intestinal pseudo-obstruction. Two patients with large intestine-dominant lupus enteritis developed intestinal pseudo-obstruction either before or after diagnosis of lupus enteritis. Five patients (29%) developed recurrence during a median observation period of 7.2 years (1.4-14.4 years). In conclusion, large intestine-dominant lupus enteritis resembles intestinal pseudo-obstruction and these two diseases may have a common pathogenesis.

Abstract
Abstract
[Background] Axilla surgery in node-positive breast cancer is dramatically changing from axillary lymph node dissection (ALND) to sentinel node biopsy (SNB). From the results of ACOSOG Z0011, IBCSG23-01 and AMAROS trials, adjuvant therapy and regional node irradiation could reduce regional lymph node recurrence for sentinel node-positive breast cancer patients. However, optimal indication of SNB alone remains uncertain. Trial design: To evaluate the outcome of sentinel node-positive breast cancer patients, the Japanese Society for Sentinel Node Navigation Surgery (SNNS) conducted a prospective cohort study in 2013 (UMIN000011782, Jpn J Clin Oncol, p.876-9, 2014). [Eligibility criteria] For eligible patients, SNB was performed or scheduled after 1 January 2012. Then 1 to 3 positive micrometastases or macrometastases in sentinel lymph nodes are confirmed by histological or molecular diagnosis. Primary chemotherapy before or after SNB is also acceptable for registration. [Specific aims] The primary endpoint is the 5-year recurrence rate of regional lymph node in patients treated with SNB alone. The secondary endpoint is the 5-year overall survival rate of this cohort. Patients treated with SNB followed by ALND are also registered simultaneously to compare the prognosis. The propensity score matching (PSM) is used to make the distributions of baseline risk factors comparable. [Statistical method] Based on an estimated recurrence rate of 5% at 5 years among patients treated with SNB alone, 240 patients are needed to give a 80% power to reject the null hypothesis that the recurrence rate is 10% with a one-sided type I error rate of 2.5%. If we consider that some patients will be lost to follow-up or become ineligible, a total of 250 patients will be needed to comprise the sample. [Present accrual] Eight hundred and eighty patients who underwent SNB alone or SNB followed by ALND were registered from 27 participating institutes between 2013 and 2016. Data cleaning is being performed. Patient's background and PSM will be reported.

Abstract
Abstract
Background: Pertuzumab provided overall and progression-free survival (PFS) benefits in HER2-positive metastatic breast cancer patients (pts) in the CLEOPATRA (Clinical evaluation of docetaxel, pertuzumab and trastuzumab) study. However, few studies have described the efficacy of other drugs in combination with pertuzumab plus trastuzumab. Here, we present a pre-specified analysis of eribulin in combination with pertuzumab plus trastuzumab as first- and second-line therapy for advanced or metastatic breast cancer (AMBC) in a multicenter, open-label phase II study (UMIN000012232, JBCRG-M03).
Methods: HER2-positive AMBC with no or single prior chemotherapy for AMBC were enrolled. All pts were administered trastuzumab and taxane as adjuvant or first-line chemotherapy. Treatment consisted of eribulin 1.4 mg/m2 on days 1 and 8 of a 21-day cycle and trastuzumab (8 mg/kg loading dose, then 6 mg/kg) plus pertuzumab (840 mg/body loading dose, then 420 mg/ body) once every 3 weeks, all administered intravenously. The primary endpoint was PFS, and secondary endpoints included overall response rate (ORR) and safety. PFS was determined using Kaplan–Meier analysis. Tumor response was assessed according to RECIST ver. 1.1.
Results: Fifty pts were enrolled from November 2013 to April 2016. Forty-nine pts were eligible for safety analysis and the full analysis set (FAS) included 46 pts. The median age was 56 years (23–70), and 8 (16%) and 41 (84%) pts were treated in first- and second-line settings, respectively. Eleven pts (23.9%) were de-novo Stage 4, and 35 pts (76.1%) had progressed in metastatic disease after completion of local therapy. Median PFS was 9.3 months (M) (95% confidence interval [CI]: 6.4–12.3). Table 1 shows the efficacy data for each treatment line and includes ORR, complete response rate (CR), partial response rate (PR), stable disease rate (SD), progressive disease rate (PD), not evaluable rate (NE) and PFS in the FAS. The median relative dose intensities of eribulin, trastuzumab, and pertuzumab were 93.3% (77.0%–100%), 100% (96.0%–100%), and 100% (89.7%–100%), respectively, in the FAS. The grade 3/4 adverse events (AE) were neutropenia in 5 pts (10.2%), including 2 pts (4.1%) with febrile neutropenia; hypertension in 3 pts (6.1%), and other AEs in only one patient. The average of the ejection fraction did not decrease significantly. Symptomatic left ventricular systolic dysfunction was not observed.
Conclusion: In pts with HER2-positive AMBC, first- and second-line therapy of eribulin in combination with pertuzumab plus trastuzumab demonstrated substantial antitumor activity with an acceptable safety profile. We are planning a phase III study comparing eribulin with taxanes in combination with pertuzumab plus trastuzumab for the treatment of HER2-positive AMBC.

Abstract
Abstract
Background: Obesity and insulin resistance are associated with inferior levels of chemosensitivity and overall prognosis for breast cancer (BC) treatment. Recent studies suggest that the quality and quantity of visceral adipose tissue (VAT) play a significant role in adipocyte function, and are related to insulin resistance. We therefore tested the hypothesis that high amount and low quality of VAT worsen treatment outcomes via insulin resistance mechanisms.
Patients and Methods: We examined two independent studies: a cross-sectional study (cohort 1) and a retrospective study (cohort 2). Cohort 1 included 106 women with early-stage BC who were undergoing surgery. Patients with normal weight (17.5< body mass index [BMI, kg/m2] ≤25, n = 53) and overweight/obese patients (BMI >25, n = 53) were selected by a pair-matching method. Insulin resistance was evaluated by HOMA-R: fasting insulin (microU/L) × fasting glucose (nmol/L)/22.5. And insulin-like growth factor (IGF) family including IGF-1 and IGF-binding protein 3 (IGFBP3) were measured before beginning treatment. The amounts of visceral fat (aVAT) was measured by 3-dimensional volumetric software using the stocked computed tomography (CT) imaging data. The quality of VAT was assessed based on the mode value of CT Hounsfield Unit of VAT (VAT-HU) at navel level of CT axial view. The association between the former variables and the quality and quantity of VAT was analyzed. Cohort 2 included 271 patients who received chemotherapy in the neo-adjuvant (NAC) or adjuvant setting. Imaging analysis was performed in the same way, and the association between those values and survival outcome after chemotherapy was analyzed by retrospective chart review.
Results: In cohort 1, aVAT was significantly correlated with serum insulin and HOMA-R levels (Pearson's R 0.44 and 0.42, respectively; P<0.05). On comparing the two groups divided by BMI, the levels of IGF-1 and IGFBP3 were not significantly different between the normal weight and the overweight/obese groups (P = 0.31 and 0.77, respectively). However, the overweight/obese group demonstrated significantly higher HOMA-R (P<0.05). In cohort 2, aVAT was significantly correlated with BMI (P<0.05). In a multivariate analysis, pathological complete responses were not associated with aVAT (P = 0.60). After a median follow-up of 112 months, tertile stratification revealed that the third tertile of aVAT had a significantly shorter distant disease free survival (DDFS) in the NAC setting (p<0.05). When adjusted by covariates in the Cox proportional regression model, aVAT and VAT-HU demonstrated significant contribution to a worsened DDFS ([p<0.05, hazard ratio {HR} 1.39; 95% confidence interval {CI} 1.11 to 1.75] and [p<0.05, HR 1.20, 95% CI 1.01 to 1.43], respectively).
Conclusions: Our study found that high amounts and low quality of VAT worsen treatment outcomes. Furthermore, we found that insulin resistance was related to those two factors. Although further validation is needed, our present work suggests the importance of evaluating the quality and quantity of visceral fat for estimating insulin resistance and treatment outcomes after chemotherapy for patients with early-stage BC.

Abstract
Recently, multiparticle-correlation measurements of relativistic p/d/^{3}He+Au, p+Pb, and even p+p collisions show surprising collective signatures. Here, we present beam-energy-scan measurements of two-, four-, and six-particle angular correlations in d+Au collisions at sqrt[s_{NN}]=200, 62.4, 39, and 19.6 GeV. We also present measurements of two- and four-particle angular correlations in p+Au collisions at sqrt[s_{NN}]=200 GeV. We find the four-particle cumulant to be real valued for d+Au collisions at all four energies. We also find that the four-particle cumulant in p+Au has the opposite sign as that in d+Au. Further, we find that the six-particle cumulant agrees with the four-particle cumulant in d+Au collisions at 200 GeV, indicating that nonflow effects are subdominant. These observations provide strong evidence that the correlations originate from the initial geometric configuration, which is then translated into the momentum distribution for all particles, commonly referred to as collectivity.

Abstract
AIM Combination therapy with sofosbuvir and ribavirin (SOF/RBV) has been recently available for chronic hepatitis C patients with genotype 2 (CHG2) in Japan. The domestic phase III clinical trial showed a high antiviral effect with a relatively safe adverse event (AE) profile. Our aim was to report an important AE detected during treatment. METHODS A prospective multi-institutional study of 12-week combination therapy with SOF/RBV for CHG2 was carried out to evaluate efficacy and safety. RESULTS The eligible subjects included 142 patients. Out of 50 assessable patients, 16% of the patients were diagnosed with hyperuricemia. The proportions of subjects with grade 1, grade 3, and grade 4 hyperuricemia were 12, 2, and 2%, respectively. Serum uric acid (UA) levels at week 1 of the therapy (W1) were numerically the highest during therapy in patients with hyperuricemia, and the ratio of W1/baseline serum UA levels was significantly higher than that of post-treatment week 4 or 8/baseline serum UA levels in assessable patients. Serum UA levels at W1 were significantly correlated with body mass index. The difference between serum UA levels at W1 and baseline serum UA levels was significantly correlated with the difference between serum creatinine levels at W1 and baseline serum creatinine levels. CONCLUSIONS Elevated serum UA level was a notable AE associated with SOF/RBV therapy for CHG2. However, because of the small number of subjects, the exact frequency of AEs should be re-evaluated with larger cohorts. We need to remember that elevated serum UA level might develop during the therapy, especially at W1.

Abstract
During 2015, the Relativistic Heavy Ion Collider (RHIC) provided collisions of transversely polarized protons with Au and Al nuclei for the first time, enabling the exploration of transverse-single-spin asymmetries with heavy nuclei. Large single-spin asymmetries in very forward neutron production have been previously observed in transversely polarized p+p collisions at RHIC, and the existing theoretical framework that was successful in describing the single-spin asymmetry in p+p collisions predicts only a moderate atomic-mass-number (A) dependence. In contrast, the asymmetries observed at RHIC in p+A collisions showed a surprisingly strong A dependence in inclusive forward neutron production. The observed asymmetry in p+Al collisions is much smaller, while the asymmetry in p+Au collisions is a factor of 3 larger in absolute value and of opposite sign. The interplay of different neutron production mechanisms is discussed as a possible explanation of the observed A dependence.

Abstract
Enzymatic hydrolysates were prepared from commercially available kamaboko type samples using three gastrointestinal proteases and protein proteases. The yields of these hydrolysates were about 10–31% and these protein contents ranged from 62 to 533 g/mg per sample powder on their wet weight basis. The hydrolysates showed higher antioxidative activities and scavenging activities against active oxygen species such as hydroxyl radical and superoxide anion radical. Moreover, these hydrolysates exhibited high angiotensin I-converting enzyme inhibitory activites that were similar or higher than those from various fermented foods such as fish sauce, sake, soy sauce, vinegar, miso and natto. The antioxidative and antihypertensive activities of commercially available kamaboko type samples were not related to the colour of the samples. The results indicated that enzymatic hydrolysates from commercially available kamaboko type samples, whose health benefits are scientifically supported, have the potential to be an increasingly important component of a healthy lifestyle and to be beneficial to the public and the food industry.

[PMID: 27653863 DOI: 10.1016/j.jns.2016.08.002] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2016] [Revised: 07/17/2016] [Accepted: 08/01/2016] [Indexed: 11/30/2022]
Abstract
Guillain-Barré syndrome (GBS) is the commonest cause of flaccid paralysis worldwide. Miller Fisher syndrome (MFS) is a variant of GBS characterized by ophthalmoplegia and ataxia. Together GBS and MFS form a continuum of discrete and overlapping subtypes, the frequency of which remains unknown. We retrospectively analysed the clinical features (antecedent symptoms, pattern of neurological weakness or ataxia, presence of hypersomnolence) of 103 patients at a single hospital in Japan. Patients were then classified according to new diagnostic criteria (Wakerley et al., 2014). Laboratory data (neurophysiology and anti-ganglioside antibody profiles) were also analysed. According to the new diagnostic criteria, the 103 patients could be classified as follows: classic GBS 73 (71%), pharyngeal-cervical-brachial weakness 2 (2%), acute pharyngeal weakness 0 (0%), paraparetic GBS 1 (1%), bifacial weakness with paraesthesias 1 (1%), polyneuritis cranialis 0 (0%), classic MFS 18 (17%), acute ophthalmoparesis 1 (1%), acute ptosis 0 (0%), acute mydriasis 0 (0%), acute ataxic neuropathy 1 (1%), Bickerstaff brainstem encephalitis 3 (3%), acute ataxic hypersomnolence 0 (0%), GBS and MFS overlap 1 (1%), GBS and Bickerstaff brainstem encephalitis overlap 1 (1%), MFS and pharyngeal-cervical-brachial weakness overlap 1 (1%). Application of the new clinical diagnostic criteria allowed accurate retrospective diagnosis and classification of GBS and MFS subtypes.

Transvenous Embolizations of Venous Compartments of Dural Arteriovenous Fistulas within Venous Sinus Walls. Interv Neuroradiol 2016; 3 Suppl 2:97-100. [DOI: 10.1177/15910199970030s219] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/1997] [Accepted: 09/18/1997] [Indexed: 11/15/2022] Open
Abstract
Transvenous embolization of venous compartments within the venous sinus wall was the method initially attempted for closing dural arteriovenous fistulas in 15 patients (22 sinuses). The venous channel, separate from the sinus lumen and located in the venous sinus wall, could be embolized in 6 lesions (3 patients), including 3 superior sagittal sinus fistulas, 2 transverse sinus fistulas, and 1 straight sinus fistula. This technique resulted in closure of the fistulas and preservation of sinus patency as well as immediate improvement of clinical symptoms. The embolizable venous compartment of the fistula within the venous sinus wall could be detected by preoperative angiography, magnetic resonance imaging, and intraoperative venography. This unique drainage of dural arteriovenous fistulas may develop concurrently with more obvious portions of the fistula. Transvenous embolization of these venous compartments can close the fistulas and normalize impaired sinus function.

The expression of miR-125b-5p is increased in the serum of patients with chronic hepatitis B infection and inhibits the detection of hepatitis B virus surface antigen. J Viral Hepat 2016; 23:330-9. [PMID: 26924666 DOI: 10.1111/jvh.12522] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2015] [Accepted: 01/14/2016] [Indexed: 01/20/2023]
Abstract
MicroRNAs were first discovered as small endogenous RNA molecules and some viruses have been reported to interact with host miRNAs. By investigating miRNA expression in serum derived from HBV-infected patients, we have clarified the relationship between miRNA expression and chronic HBV infection. Additionally, we demonstrate the use of miRNAs as both novel biomarkers and new therapies against HBV. We included the sera of 20 patients with chronic HBV infection, sera of 20 patients with HCV infection and sera of 10 healthy controls in this study. The miRNA libraries were sequenced using a 32-mer single end sequence. The validation study of circulating miRNA in serum was conducted by qRT-PCR. The HBV genomic regions of genotype B and genotype C that were speculated to be targeted by miRNA were constructed using complementary oligonucleotides in the vectors. Reporter assays were performed 48 h after transfection. The expression levels of 21 miRNAs were found to be differentially expressed in the three groups. 10 miRNAs (hsa-miR-100-5p, miR-125b-5p, miR-193b-3p, miR-194-3p, miR-30a-3p, miR-30c-2-3p, miR-3591-5p, miR-4709-3p, miR-574-3p and miR-99a-5p) were found to be upregulated in CH-B by deep sequence analysis. The computer analysis showed that two regions of HBsAg are potential targets of miR-125b-5p and miR-30c-2-3p and that these miRNAs may downregulate the expression of HBV-S. The HBV genotype C segment speculated to be targeted by hsa-miR-125b-5p significantly decreased the expression of the reporter. This study indicated that expression of miR-125b-5p was related to the etiology of chronic hepatitis B infection and regulated the expression of HBsAg.

Donor site selection and clinical outcomes of nipple-areola skin-sparing mastectomy with immediate autologous free flap reconstruction: A single-institution experience. Eur J Surg Oncol 2015; 42:369-75. [PMID: 26792708 DOI: 10.1016/j.ejso.2015.12.002] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2015] [Revised: 11/14/2015] [Accepted: 12/01/2015] [Indexed: 11/28/2022] Open
Abstract
BACKGROUND The objective of this study was to examine the clinical outcomes of immediate breast reconstruction using perforator flaps from different donor sites, and to characterize the trends among these flaps. METHODS We retrospectively reviewed 136 consecutive patients who underwent immediate breast reconstruction using free flaps after skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM). The whole breast was pathologically analyzed in 5-mm sections. Breast reconstruction was performed using the deep inferior epigastric perforator (DIEP) flap, gluteal artery perforator (GAP) flap, and posterior medial thigh perforator (PMTP) flap. Patient characteristics were compared among donor sites. RESULTS NSM was converted to SSM because of intraoperative subareolar tumor positivity in 7 of 107 patients. Eleven patients had positive margins in permanent sections. All but one patient had a positive horizontal margin in the peripheral direction. The 5-year recurrence-free survival rate was 91.9%. The locoregional recurrence rate was 5.1% with a mean follow-up observation period of 75 months. DEIP, GAP, and PMTP flaps were used in 64 (47.1%), 38 (27.9%), and 34 (25.0%) patients, retrospectively. DIEP flaps were used in older patients and those with a higher body mass index. GAP flaps were used in younger patients. DIEP and GAP flaps were used for larger breasts, and PMTP flaps for smaller breasts. CONCLUSION NSM or SSM with immediate perforator flap breast reconstruction is an oncologically acceptable surgical option. We believe that age, desire to have children, body mass index, and excised breast volume are valuable factors for selecting the optimal donor site.

Clinicopathological and prognostic significance of interleukin-8 expression and its relationship to KRAS mutation in lung adenocarcinoma. Br J Cancer 2014; 110:2047-53.

Abstract
Background: On the basis of our recent findings of oncogenic KRAS-induced interleukin-8 (IL-8) overexpression in non-small cell lung cancer, we assessed the clinicopathological and prognostic significances of IL-8 expression and its relationship to KRAS mutations in lung adenocarcinomas. Methods: IL-8 expression was examined by quantitative RT–PCR using 136 of surgical specimens from lung adenocarcinoma patients. The association between IL-8 expression, clinicopathological features, KRAS or EGFR mutation status and survival was analysed. Results: IL-8 was highly expressed in tumours from elderly patients or smokers and in tumours with pleural involvement or vascular invasion. In a non-smokers' subgroup, IL-8 level positively correlated with age. IL-8 was highly expressed in tumours with KRAS mutations compared with those with EGFR mutations or wild-type EGFR/KRAS. Lung adenocarcinoma patients with high IL-8 showed significantly shorter disease-free survival (DFS) and overall survival (OS) than those with low IL8. DFS and OS were significantly shorter in the patients with mutant KRAS/high IL-8 than in those with wild-type KRAS/low IL-8. Cox regression analyses demonstrated that elevated IL-8 expression correlated with unfavourable prognosis. Conclusions: Our findings suggest that IL-8 expression is associated with certain clinicopathological features including age and is a potent prognostic marker in lung adenocarcinoma, especially in oncogenic KRAS-driven adenocarcinoma.
