Abstract
OBJECTIVES To compare the discriminative capabilities for the manifestation of sarcopenia or physical frailty between serum creatinine- and cystatin C-derived indices among community-dwelling older adults. DESIGN Cross-sectional study. SETTING Primary Care and Community. PARTICIPANTS We utilized a subset of data from the Frail Elderly in the Sasayama-Tamba Area (FESTA) study, which was initiated in 2015 to gather comprehensive information on various health-related parameters among community-dwelling older individuals (age ≥65 years). MEASUREMENTS Five serum creatinine-cystatin C based indices including the Sarcopenia Index, the serum creatinine/cystatin C ratio, the disparity between serum cystatin-C-based and creatinine-based estimated GFR, the total body muscle mass index (TBMM), and the prediction equation for skeletal muscle mass index (pSMI) were employed. Sarcopenia and physical frailty were identified based on the Asian Working Group for Sarcopenia criteria and the revised Japanese version of the Cardiovascular Health Study criteria, respectively. The receiver operating characteristic (ROC) and logistic regression analyses were performed to assess the discriminative abilities of these tools. RESULTS In the analysis of 954 participants, 52 (5.5%) were identified with sarcopenia and 35 (3.7%) with physical frailty. Regarding sarcopenia discrimination, TBMM and pSMI both exhibited area under the curve (AUC) values exceeding 0.8 for both men and women. Concerning the identification of physical frailty, AUC values ranged from 0.61 to 0.77 for males and 0.50 to 0.69 for females. In the multivariate logistic regression analyses, only TBMM and pSMI consistently displayed associations with sarcopenia, irrespective of sex (P<0.001, respectively). On the other hand, no consistent associations were observed between the indices and physical frailty. CONCLUSIONS This study provides a robust association of a serum creatinine- and cystatin C-derived indices, especially TBMM and pSMI, with sarcopenia among community-dwelling older adults. Conversely, the application of these indices for the screening of physical frailty has its constraints, necessitating further investigation.

Abstract
Traditionally, abstinence has been regarded as the only appropriate goal in the treatment of alcohol dependence in Japan. Recently, harm reduction by reducing alcohol consumption, which has been used as a treatment approach in Europe, has gained recognition in Japan. The 2018 guideline for the treatment of alcohol dependence in Japan recommends abstinence as the primary goal, but reduction of alcohol consumption is described as an appropriate treatment goal in some patients. Nalmefene is an opioid modulator that is used to reduce alcohol consumption in patients with alcohol dependence. Here, we report the clinical course of alcoholic liver cirrhosis in alcohol-dependent patients who were treated with nalmefene for three months. Their alcohol consumption was reduced, which led to an improvement in liver function. Nalmefene provides a clinical benefit, constitutes a potential pharmacological treatment paradigm in terms of the treatment goal and dosing regimen, and addresses an unmet medical need in patients with alcohol dependence who need to reduce their alcohol consumption.

Abstract
Abstract
Background
The age-adjusted prevalence rate of atrial fibrillation (AF) had kept increasing until 2-year after the Great East Japan Earthquake (reported in ESC2017). Whether the elevated prevalence was tentative or not has not been sufficiently elucidated yet.
Methods
Community dwellers aged 40 to 74 years living in Iwate Prefecture who underwent annual health checkups (2010 (n=17490), 2011 (n=174236), 2012 (n=183612), 2013 (n=188429), 2014 (n=188424), 2015 (n=193610), 2016 (n=194882), 2017 (n=195428) account for approximately 30% of total population) were enrolled. Participants were divided into two age categories (40–64, 65–74 years). Direct age-adjusted prevalence rate of AF in each year was estimated using the 2010 population as the reference.
Result
Data are shown in the figure.
Conclusion
Prevalence rates of AF increased only in elderly people for up to 3 years after the disaster. This indicated that accelerated development of AF in elderly people due to stressful life after the disaster would not end within a short term and lasted at least 3 years after the disaster.

Abstract
Abstract
Background
Atrial fibrillation (AF) is one of the important factors of cardiovascular morbidity and mortality and to find not only patients with persistent AF but also individuals with paroxysmal AF among apparently healthy people is a crucial strategy for decreasing number of patients with serious cardio-embolic stroke. However, screening ability using previously known risk factors for future development of AF has not been examined in individuals with paroxysmal AF.
Methods
A total of 59730 male individuals, aged 40 years or older who underwent multiple comprehensive physical check-ups including 12 lead electrocardiogram (ECG) from 2012 to 2015 were enrolled. Persistent AF was defined a case that consecutively manifested AF till the last checkup. Paroxysmal AF was defined as a case who transiently manifested AF in each of the checkup and subsequently manifested sinus rhythm at the last checkup. Non-AF was defined as a case that never manifested AF in any of checkup. Age-adjusted prevalence rates and their 95% confidence intervals of known-risk factors in the first survey were estimated by logistic regression analysis separately by the three groups (non-AF (n=58602), paroxysmal AF (n=392) and persistent AF (736)).
Results
Age-adjusted prevalence rates (95% confidence interval) of risks factors for AF are shown in the table. Already known risk factors were evidently manifested in persistent AF group, however, prevalence rates of these factors in paroxysmal AF group were not different from the rates in non-AF group.
Conclusion
The repeated measurements of ECG study indicated that individuals who would develop paroxysmal AF in the near future did not have typical risk factors for AF and a screening test using risk factors for AF have no chance to find a high-risk individual for paroxysmal AF.

Abstract
Abstract
Introduction
Recently “Dense breast” has attracted numerous attention because of diagnostic difficulty in mammography among those harboring dense breast, which is far more frequent in Asian than Caucasian women. Therefore, in this study, we retrospectively evaluated the risks of subsequent development of malignancy through comparing the detailed mammographic characteristics between Japanese subjects harboring dense and non dense breasts.
Methods
We retrospectively examined mammorgraphic findings taken from March 2013 to March 2016 at Nahanishi Clinic, Okinawa, Japan. We stratified its density according to the suggestion of the Japan Central Organization on Quality Assurance of Breast Cancer Screening, which was defined by the proportion of fat area as follows; extremely high dense:10-20%, heterogeneously dense:40-50%, scattered fatty:70-90%, fatty: almost all the breast fat. “Dense breast” includes extremely high and heterogeneous dense. We evaluated the detailed radiological findings of each phenotypes including the characteristics of the mass, calcification and focal asymmetric density(FAD) and architectural distortion. We also compared the rates of subsequent cancer development and sensitivity of detecting cancer between those harboring dense and non dense breasts.
Results
We reviewed the mammography findings of 7747 Japanese women including 857 with breast cancers. When adjusted for age, the rate of dense breast was significantly associated with age, 88.6% in women in their 20s(vs40s p<0.001 OR3.402), with incremental decrease, 80.4% in 30s(P<0.001 OR1.802), 69.5% in 40s, 55.9% in 50s(P<0.001 OR0.512), 32.3% in 60s(P<0.001 OR 0.108), 19.5% in 70s(P<0.001 OR 0.106) and 5.3% in over 80s(P<0.001 OR0.024). The rate of malignancies was 9.1% (385) in dense and 13.6% (472) in non dense breasts. We then compared the mammographic findings between dense and non dense breast. Abnormal calcifications were detected more frequent(7.6%vs5.3% P<0.001 OR1.478) but masses less so(16.4%vs23.7% P<0.001 OR 0.632) in dense breast, while no significant differences detected in FADs(4.9%vs4.6% P=0.35 OR1.074) and distortions(1.2%vs1.4% P=0.29 OR=0.859) between dense and non dense breast. The rate of carcinoma was less frequent in dense breast among those associated with mammographic calcification(19%vs27.3% P<0.01 OR0.626) but more frequently in dense breast among those with masses (13%vs19% P<0.001 OR0.628). The rate of carcinoma was not different between dense and non dense breast in those with FADs (21.6vs20.6% P=0.72 OR1.067) and distortions(71.7%vs74.7% P=0.64 OR0.857). In addition, among 37 breast cancer patients who did not harbor the mammographic findings above (26 dense and 11 non dense breasts), the average mass length was significantly larger in dense (13.6mm) than non-dense breast (9.9mm) (P=0.018 used Welch's t test), respectively.
Conclusion
Results of our present study did demonstrate that detection of malignancy in those with mammographic dense breast is more difficult. Therefore, in those harboring dense breast in mammography, addition of other modalities such as US could improve the detection of breast carcinoma.

Abstract
Abstract
Aromatase inhibitors (AIs) have been used in the adjuvant treatment of postmenopausal women with hormone receptor positive early breast cancer as a consequence of the significant benefit in DFS and OS when compared with tamoxifen. However the patients who receive AIs have an increased risk of arthralgia, at most 50% of patients did not take AIs and the 20% of the discontinued patients were within the first year of use. The HOPE study demonstrated that exercise was effective in improving AI-induced arthralgia. We conducted the AIAI (Arthralgia Improvement for the patients with Aromatase Inhibitors) study using wider eligibility criteria that the HOPE study to assess the impact on AI induced arthralgia in breast cancer patients.
Patients were randomly assigned, in a 3:1 ratio, to exercise intervention or usual care. Following randomization participants could choose from 3 types of exercise including group 1 (120-150 minutes per week of walking or running), group 2 (daily NIPPON HOSO KYOKAI: NHK broadcast exercise in Japan) and group 3 (going up the stairs- frequency, etc). The primary endpoint was the arthralgia change at 6 and 12 months, which was assessed using the BPI (Brief Pain Inventory). Secondary endpoints included the BPI according to the completion rate of exercise (70% and more or less than 70%), the BPI change of the patients with arthralgia (the patients who had arthralgia at the time they enrolled this study; BPI worst pain 3≤), the BPI of the each exercise group, the BPI according to the duration of AIs therapy (24 months and more or less than 24 months), the correlation between the BMI change and the BPI change, adherence of AIs and safety.
102 were randomly assigned to exercise intervention group (22 patients dropped out of this study) and 37 to usual care group (9 patients dropped out of this study).Trends for differentiations of pain interference at 12 months was detected between exercise intervention group and usual care group, but the differences did not reach statistical significance (p = .067). There was statistically better pain interference of the 70% and more exercise completion group than the usual care group at 12 months (-0.29±1.22 for exercise intervention group and 0.33±0.88 for usual care group, p= .002). The change of pain interference was statistically better for the exercise intervention group than the usual care group at 12 months (p= .017, -0.61±0.69 for exercise intervention group and 1.14±1.56 for usual care group). There was statistically significant difference of pain interference between group 1 exercise intervention group and the usual care group at 12 months (-0.14±0.68 for group 1 exercise intervention group and 0.33±0.88 for the usual care group, p= .009). Tendencies were detected in the AIs therapy less than 24 months group. Trends for the correlation between BPI and BMI were detected in worst pain at 6 month, pain severity at 6 month and pain interference at 12 month. There was a statistically significant difference of AIs adherence between the exercise intervention group (99%) and the usual care group (92%) (P=0.03).
Exercise may be effective in improving and preventing AI-induced arthralgia.

Abstract
Abstract
Purpose: Arthralgia sometimes occurs in the breast cancer patients treated with aromatase inhibitors (AIs). It is one of the most important reasons for poor AIs adherence.
Background; The HOPE study previously demonstrated that exercise was effective in improving AI-induced arthralgia in breast cancer patients. However, recruitment to this study was limited to severe cases (Criteria; physically inactive, >6 months AT treatment, >2 months arthralgia). To asses if these findings were more generalizable to all breast cancer contexts we conducted a randomized trial of exercise intervention using wider eligibility criteria that the hope study to assess the impact on AI induced arthralgia in breast cancer patients.
Methods: We examined Japanese breast cancer patients operated at Nahanishi Clinic, Okinawa, Japan. Following the informed consent the patients were randomly assigned to a 3:1 ratio to exercise intervention or usual care, . Eligibility criteria included receiving an AI for 0-4 years, no metastases, any arthralgia level and any exercise habits. Following randomization participants could choose from 3 types of exercise including strong (120-150 minutes per week of walking or running), intermediate (gentle calisthenics (daily NIPPON HOSO KYOKAI: NHK broadcast exercise)) and weak (going up the stairs- frequency). Arthralgia was assessed using the Brief Pain Inventory (BPI), in which the patients completed a baseline, 6month and 12 month BPI assessment. Primary endpoint was BPI change at 12 months.
Results: Among 227 women screened, we randomized 108 women, with 80 to exercise intervention (46 of strong, 19 of intermediate and 15 of weak) and 28 to usual care. Base line BPI were well balanced between exercise intervention and usual care. Overall exercise intervention reduced BPI scores relative to control. The BPI changes of worst pain, least pain, average pain and pain right now were 0.09, -0.25, -0.14 and 0 for exercise intervention group and 0.21, 0.46, 0.07 and 0.61 for usual care group, respectively. There was a statistically significant difference of AIs adherence between exercise intervention group (99%) and usual care group (92%) (P=0.03).
Conclusion: Exercise intervention tends to improve the AI-induced arthralgia and has a positive effect on AIs adherence.

Abstract
The effectiveness of hepatitis C treatment has improved with the development of interferon (IFN), and it has drastically improved with the development of peg-interferon-α (PEG-IFN) in combination with ribavirin (RBV) and, more recently, with the addition of a protease inhibitor. Simeprevir, which is a second-generation protease inhibitor, has shown clinically favorable safety and tolerability profiles. Simeprevir received its first global approval in Japan in September 2013 for the treatment of genotype 1 chronic hepatitis C in combination with PEG-IFN and RBV. One serious adverse event associated with IFN therapy is interstitial pneumonitis, which can be fatal. We experienced a patient with interstitial pneumonitis that was induced by simeprevir with PEG-IFN and RBV therapy for chronic hepatitis C in the early stages of therapy (8 wk after initiating therapy). This is the first case report of interstitial pneumonitis with simeprevir with PEG-IFN and RBV in the world. In addition, it is very interesting that the onset of interstitial pneumonitis was earlier than that in conventional PEG-IFN and RBV therapy. This finding suggests that simeprevir augments the adverse event. We present this case report in light of relevant literature on interstitial pneumonitis with conventional PEG-IFN and RBV therapy.

Abstract
The "complete cure" of onychomycosis requires long-term treatment with a systemic antifungal agent. Therefore, to properly assess the effects of an antifungal agent on onychomycosis requires a long follow-up. We have conducted a retrospective analysis of the patients treated with griseofulvin (GRF) from 1962 to 1992 and a clinical study to compare the long-term effect of GRF with that of a new oral antifungal agent, itraconazole (ITCZ), for patients who received treatment from 1992 to 1995. For the retrospective study, 281 patients who were microscopically diagnosed as having onychomycosis at the Department of Dermatology, Faculty of Medicine, University of Tokyo, and received GRF administration in 1962, 1972, 1982, and 1992, were evaluated for cure rate and dropout rate. The total cure rate was 29.2%, but the cure rate was 68.8% for the patients who continued their medication for more than one year. For the comparative study, 139 patients who received the treatment at the same institution between 1992 and 1995 were evaluated. The cure rate and the dropout rate for GRF were found to be 23.8% (23/97) and 52.6% (51/97) respectively. The cure rate and the dropout rate for ITCZ were found to be 50.0% (21/42) and 38.1% (15/42). When the two treatment protocols were compared for their long-term effects, we found that most of the patients treated with ITCZ were cured within 3 years, and about 30% of the patients treated with GRF remained uncured even after long-term administration of the agent. Furthermore, from a multiple regression analysis, the GRF/ITCZ administration required to cure onychomycosis was estimated to be 3.92 + 0.161 [Age (years)] + 0.635 [Number of infected toenails] months. The results of this study suggest that the biggest problem associated with the treatment of onychomycosis with an oral antifungal agent is compliance in long-term therapy. Notably, the final cure rate of ITCZ therapy went over 90%, suggesting that the low dose continuous therapy, the standard treatment protocol in Japan, was a key contributing factor for the higher cure rate for ITCZ.

Abstract
Abstract
Introduction
Much of the longevity advantage in Okinawa is thought to be related to a healthy lifestyle including traditional foods which is low in calories and dense in nutrition. However, dietary change since World War II has been largely deleterious, with younger Okinawan people developing a higher risk of obesity and other chronic disease risk factors than older Okinawan people. In addition, breast cancer incidence and mortality are gradually increasing in Okinawa. Therefore we examined the correlation between BMI and breast cancer in both premenopausal and postmenopausal women in Okinawa.
Methods
The cases were 3422 female breast cancer patients without any previous breast cancer history, and the control subjects were 5622 women, who initially visited Nahanishi Clinic Okinawa in Okinawa, Japan, between May 1996 and March 2013. The median ages were 53 years old (21-99) in the breast cancer group and 44 years old (18-90) in the control group. Based on the World Health Organization classification, 25≤BMI<30 is considered as overweight and 30≤BMI as obesity. We examined the association between BMI and breast cancer risk by odds ratio. In addition, we also stratified and examined the BMI according to menstruation and age by student t test.
Results
Table.1 summarized the results of the association between BMI and breast cancer risk.

Being overweight, or obese, increased the odds of breast cancer, as well as these put together, in the postmenopausal group (p<0.001, respectively). As for the premenopausal group, being overweight and also overweight grouped with obese increased the odds of breast cancer significantly (p = 0.002 and p<0.001, respectively) and a tendency was detected in the obese (p = 0.064). Table.2 summarized the results of BMI according to menstruation and age.

The BMI of the breast cancer group were statistically higher than that of the control group in those over 30 years old, and in the pre and post menopausal (p<0.001, respectively).
Conclusion
The results of this study suggested that weight gain and consequently being overweight or obese might increase the odds for breast cancer in both premenopausal and postmenopausal women ages over 30 years old in Okinawa.

Abstract
Abstract
Introduction
The two major susceptibility genes for breast cancer and ovarian cancer, BRCA1 andBRCA2 were discovered in 1994 and 1995, respectively. Various risk prediction algorithms and models have been developed to identify putative BRCA1/2 mutation carriers. Myriad Genetic Laboratories, Inc. released Mutation Prevalence Tables (http://www.myriad.com/lib/brac/brca-prevalence-tables.pdf#search = ‘Myriad+Genetic+Laboratories%2C+Inc.+Mutation+Prevalence+Table’) through its clinical testingservice. To the best of our knowledge, this is the first study to examine the correlation between this risk prediction model and clinicopathological characteristics of breast cancer patients.
Methods
The cases were 148 female breast cancer patients without any previous breast cancer history who initially visited Nahanishi Clinic Okinawa in Okinawa, Japan, between May 2012 and March 2013. The median ages were 55 years old (26-84). We examined the correlation between Myriad Genetic Laboratories, Inc. released Mutation Prevalence Tables and clinicopathological characteristics including age, ER, PgR, HER2, triple negative status, histological grade and Ki67. The presence of ER and PgR was determined by nuclear staining with positive cases defined as more than 1% staining according to ASCO CAP. With regard to HER2 evaluation, membranous staining was graded as 0-1+, 2+, and 3+. Samples scored as 2+ were subjected to FISH. Positivity was defined as a HER2:CEP17 signal ratio>2.2. Ki-67 labeling index was obtained by selecting the hot spots after evaluation at low power magnification and counting 1000 tumor cells in the hotspots.
Results
There was statistically negative correlation between the risk prediction rates and age (r = -0.480, r2 = 0.230, p<0.001). The risk prediction rates of ER negative and positive were 2.93±4.12% and 4.06±9.53% with statistically significant differences (p = 0.049).On the other hand, tendency was detected in PgR status (p = 0.058), and the risk prediction rates were 3.21±1.92% of PgR negative and 4.24±3.34% of PgR positive, respectively. The risk prediction rates of triple negative cases and non triple negative cased were 2.58±0.94% and 4.06±3.11% with statistically significant differences (p<0.001). There were not statistically significant differences in HER2 status, histological grade and Ki67, respectively.
Conclusion
Previous studies demonstrated that BRCA1/2 mutation was associated with triple negative and high grade malignant breast cancer. However, the results of this study suggested that Myriad Genetic Laboratories, Inc. released Mutation Prevalence Tables was not associated with triple negative and/or high risk breast cancer patients in Okinawa.

Abstract
Abstract
Introduction
Acoustic radiation force impulse (ARFI) imaging is a newly developed ultrasound-based modality which could evaluate the wave propagation speed and tissue stiffness more precisely and objectively. ARFI does not require any external compression, and so even in deep tissues could, provide complementary information to conventional ultrasound (US), potentially improving the characterization of tissue and focal lesions. The generated waves can provide quantification of the shear wave velocity, termed Virtual Touch Tissue Quantification (VTTQ). VTTQ is an intrinsic and reproducible property of the tissue, and this tissue quantification could provide objective and reproducible data. This is the first study to evaluate the biological features of breast tissues using newly developed non-invasive diagnostic system VTTQ.
Methods
180 patients including 115 invasive ductal carcinoma (IDC), 30 ductal carcinoma in situ (DCIS), 4 mucinous carcinoma, 7 invasive lobular carcinoma (ILC), 8 fibroadenoma (FA), 12 fibrocystic change (FCC) and 4 intraductal papilloma were studied at Nahanishi Clinic Okinawa. We first compared results of VTTQ according to each histological subtype, and determined the optimal cutoff values for VTTQ to distinguish benign from malignant tissues using the receiver operating characteristic (ROC) method. In addition, we also examined the correlation between VTTQ velocities and Ki-67, estrogen receptor (ER), progesterone receptor (PgR) or human epidermal growth factor receptor 2 (HER2) in the cases of IDC using the linear regression analyses and Student's t test.
Results
There were statistically significant differences of VTTQ velocities between IDC and DCIS (P = 0.003), mucinous carcinoma (P = 0.009), FA (P<0.001), papilloma (P<0.001) or FCC (P<0.001). There were significant differences between DCIS and FA (P = 0.016), papilloma (P<0.001) or FCC (P<0.001). Significant differences were also detected between mucinous carcinoma and papilloma (P<0.001) or FCC (P = 0.003), between ILC and papilloma (P = 0.012) or FCC (P = 0.003) and between FA and papilloma (P = 0.030). VTTQ velocities were statistically higher in malignant cases than in benign cases (p<0.05, respectively) and the best cutoff value for the VTTQ velocity which could differentiate benign from malignant cases was 2.89 m/second. There were statistically significant correlations between VTTQ velocity and Ki-67 labeling index (r = 0.338, r2 = 0.114 and P<0.001), and significant inverse correlations between VTTQ and ER (r = -0.311, r2 = 0.097 and P<0.001) or PgR (r = -0.361, r2 = 0.131 and P<0.001) status of IDC. There was also a significant differences of the average velocities between HER2 positive (6.39±1.44 m/second) and negative (4.43±1.41 m/second) cases (P<0.001).
Conclusion
VTTQ was valuable for examination of breast cancer pathology in a non-invasive fashion. The results still could suggest the value of VTTQ examination in the clinical management of breast cancer patients. VTTQ has huge potential for examining axillary lymph node status instead of sentinel lymph node biopsy, and examining the responsiveness of neoadjuvant chemotherapy in midcourse evaluation without invasive biopsy.

Abstract
BACKGROUND AND AIM Serum des-γ-carboxy prothrombin (DCP) levels using a newly developed electrochemiluminescence immunoassay (ECLIA, novel DCP [NX-DCP]) were measured, and the utility of NX-DCP and DCP/NX-DCP ratio for the diagnosis of hepatocellular carcinoma (HCC) was investigated. Antigenic differences in DCP between HCC and non-HCC patients were elucidated. METHODS The subjects included 170 patients with HCC, 61 with benign liver disease, 12 with obstructive jaundice, and 10 warfarin users. NX-DCP was quantitated by sandwich ECLIA employing novel anti-DCP monoclonal antibodies, P11 and P16. Conventional DCP was quantitated by standard ECLIA. DCP extracted from serum by affinity-chromatography was analyzed by Western blotting. RESULTS Conventional serum DCP levels were high in patients with HCC and obstructive jaundice, and in warfarin users, consistent with previous reports. Serum NX-DCP levels were high only in warfarin users and obstructive jaundice patients (vitamin K-deficient patients) but not in HCC patients. The DCP/NX-DCP ratio was significantly higher in the HCC group than in the benign liver disease, obstructive jaundice, and warfarin groups (P < 0.001). Receiver operating characteristic analysis showed significant superiority of the DCP/NX-DCP ratio over conventional DCP as a marker for HCC diagnosis (P < 0.05). Western blot analysis showed that P11 and P16 reacted strongly with DCP from a warfarin user and an obstructive jaundice patient but very faintly with DCP from an HCC patient. Immunohistochemistry on HCC samples and autopsied normal liver tissues from warfarin users showed similar results. CONCLUSIONS The DCP/NX-DCP ratio is very useful for diagnosing HCC. DCP in HCC patients is distinct from that in vitamin K-deficient patients.

Abstract
Abstract
It is well known that estrogens play important roles in both the pathogenesis and development of invasive ductal carcinoma (IDC) of human breast. However, molecular features of estrogen actions have remained largely unclear in pure ductal carcinoma in situ (pDCIS), regarded as a precursor lesion of many IDCs. This is partly due to the fact that gene expression profiles of estrogen-responsive genes have not been examined in pDCIS. Therefore, we first examined the profiles of estrogen-induced genes in estrogen receptor (ER)-positive pDCIS and DCIS (DCIS-c) and IDC (IDC-c) components of IDC cases (n = 4, respectively) by microarray analysis. Estrogen-induced genes identified in this study were tentatively classified into three different groups in the hierarchical clustering analysis, and 33% of the genes were predominantly expressed in pDCIS rather than DCIS-c or IDC-c cases. Among these genes, the status of MYB (c-MYB), RBBP7 (RbAp46) and BIRC5 (survivin) expression in carcinoma cells was significantly higher in ER-positive pDCIS(n = 53) than that in ER-positive DCIS-c (n = 27) or IDC-c (n = 27) by subsequent immunohistochemical analysis of the corresponding genes (P < 0.0001, P = 0.03 and P = 0.0003, respectively). In particular, the status of c-MYB immunoreactivity was inversely (P = 0.006) correlated with Ki-67 in the pDCIS cases. These results suggest that expression profiles of estrogen-induced genes in pDCIS may be different from those in IDC, and c-MYB, RbAp46 and survivin may play particularly important roles among estrogen induced genes in ER-positive pDCIS.

Abstract
AIM We surveyed multiple centers to identify types and frequency of complications and mortality rate associated with radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC). METHODS We distributed a questionnaire developed by members of the Chugoku-Shikoku Society for the Local Ablation Therapy of Hepatocellular Carcinoma to 20 centers and analyzed types and frequency of complications and mortality rate. RESULTS In total, 16 346 nodules were treated in 13 283 patients between January 1999 and November 2010. Five patients (0.038%) died: two from intraperitoneal hemorrhage, and one each from hemothorax, severe acute pancreatitis and perforation of the colon. In 16 346 treated nodules, 579 complications (3.54%) were observed, including 78 hemorrhages (0.477%), 276 hepatic injuries (1.69%), 113 extrahepatic organ injuries (0.691%) and 27 tumor progressions (0.17%). The centers that treated a large number of nodules and performed RFA modifications, such as use of artificial ascites, artificial pleural effusion and bile duct cooling, had low complication rates. CONCLUSION This study confirmed that RFA is a low-risk treatment for HCC and that sufficient experience and technical skill can reduce complications.

Abstract
This study was performed to measure the activity size distribution of aerosol particles associated with short-lived radon decay products in indoor air at Nagoya University, Nagoya, Japan. The measurements were performed using a low pressure Andersen cascade impactor under variable meteorological conditions. The results showed that the greatest activity fraction was associated with aerosol particles in the accumulation size range (100-1000 nm) with a small fraction of nucleation mode (10-100 nm). Regarding the influence of the weather conditions, the decrease in the number of accumulation particles was observed clearly after rainfall without significant change in nucleation particles, which may be due to a washout process for the large particles.

Abstract
Abstract
Purpose: Triple negative breast carcinoma (TNBC) is currently being required to be classified pluralistically in order to provide the most appropriate therapy to the patients. We attempted to subclassify TNBC cases into subgroups based on clinical outcome or prognosis of the patients with TNBC using archival specimens. Materials and Methods: We analyzed 102 Japanese cases of invasive TNBC who underwent surgery between January 1998 and December 2007. The clinicopathological factors and clinical information of these patients were retrospectively retrieved from charts of the patients. Immunohistochemical staining was performed for estrogen receptor (ER), progesterone receptor (PgR), human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor 1 (EGFR1), CK5/6, Ki-67 and CD31 for microvessel density (MVD). Results: Median follow-up time of the patients was 68.5 months. Multivariable analysis demonstrated that the pathologic node status was the most significantly associated with relapse-free survival (RFS) and breast cancer-specific survival (BCSS) of the patients. Pathological tumor size, basal-like type, Ki-67 labeling index (LI) and MVD were also independently associated with RFS and BCSS. Based on these results, we devised the Risk Score system reflecting Hazard ratios (HRs) of these prognostic factors above.
Multivariate analysis and the Risk Score for TNBC patients.
With this system, TNBC patients in this study were classified into three subgroups; patients with score 0-3 are in low risk group, score 4-7 in intermediate risk group and score 8- in high risk group. These three groups had statistically significant differences for risk of relapse and breast cancer-specific death, respectively.
Conclusions: We propose the Risk Score system, which incorporated pathologic nodal status, size of the primary tumor, the presence or absence of basal-like features, Ki67 LI and MVD of the patients in order to predict postoperative clinical course of the Japanese patients with TNBC. Such a classification which can be performed in diagnostic pathology laboratory can be useful as a decision-making tool for triple negative patients.

Abstract
Abstract
Background: Vasohibin-1 is a recently identified negative feedback regulator of angiogenesis induced by vascular endothelial growth factor (VEGF)-A. This is the first study to evaluate immunoreactivity and mRNA expression of Vasohibin-1 in human breast disorders. Material and Methods: We examined 251 breast specimens including invasive ductal carcinoma (IDC: 148), ductal carcinoma in situ (DCIS:62), fibroadenoma (FA:16), inflammatory lesion (6), fibrocystic change(9) and non-pathological breast tissue(7). We immunolocalized vasohibin-1 and compared its immunoreactivity to that of VEGF-A, VEGF receptor 2 (Flk-1), CD31 and Ki-67. The correlation of vasohibin-1 immunoreactibity with overall survival (OS), and disease free survival (DFS) of the breast carcinoma patients was also evaluated. In addition, we evaluated Ki-67 and CD31, and Ki-67 and vasohibin-1 double-immunostaining for further characterization of neovascularization. We also evaluated mRNA expression of Vasohibin-1 using a real-time quantitative RT-PCR with LightCycler system.
Results: Vasohibin-1 was detected in endothelial cells of human breast and its immunodensity was significantly higher in IDC and inflammatory lesion than the other types (P<0.001). As for DCIS, there was a significant positive correlation between vasohibin-1 expression level and nuclear grade or Van Nuys classification of carcinoma cells (P<0.001). In addition, a significant positive correlation was detected between vasohibin-1 and VEGF-A, Flk-1 or Ki-67 (P<0.001). There was also positive associations between vasohibin-1 and OS (P=0.004) and DFS (P<0.001). Results of double-immunostaining demonstrated the ratio of Ki-67-positive cells among vasohibin-1-positive endothelial cells (46.5%) was significantly higher than those among CD31-positive cells (23.5%). In addition, there was a significant positive correlation between Vasohibin-1 mRNA level and Ki-67 or high nuclear grade(P<0.001).
Discussion: This is the first study demonstrating the status of vasohibin-1 in human breast lesions, which indicates that vasohibin-1 is associated with neovascularization and may especially play important roles in the regulation of intratumoral angiogenesis in human breast cancer. Vasohibin-1 is supposed to be induced in the downstream of VEGF-A/Flk-1 signaling pathway and considered an appropriate biomarker for intratumoral neovascularization. In addition, these results clearly indicated that vasohibin-1 expression may become one of the prognostic markers for metastasis and prognosis, and also become one of the appropriate biomarker of the potential of subsequent stromal invasion of carcinoma cells.

Abstract
OBJECTIVES To assess whether smoking is a risk factor for developing rheumatoid arthritis (RA). DESIGN Meta-analysis. METHOD DATA SOURCES were observational studies that examined the association between smoking history and the risk of developing RA identified through Medline and EMBASE (from 1966 to December 2006), relevant books and a reference search. Two authors independently extracted the following: authors' names, publication year, sample size, participant characteristics, odds ratios (OR) or relative risks, adjustment factors, study design and area where the study was conducted. Data syntheses were based upon random effects model. Summarised syntheses effects were expressed by OR. RESULTS Sixteen studies were selected from among 433 articles. For men, summary OR for ever, current and past smokers were 1.89 (95% CI 1.56 to 2.28), 1.87 (1.49 to 2.34) and 1.76 (1.33 to 2.31), respectively. For rheumatoid factor-positive (RF+) RA, summary OR for ever, current and past smokers were 3.02 (2.35 to 3.88), 3.91 (2.78 to 5.50) and 2.46 (1.74 to 3.47), respectively. Summary OR for 20 or more pack-years of smoking was 2.31 (1.55 to 3.41). For women, summary OR for ever, current and past smokers were 1.27 (1.12 to 1.44), 1.31 (1.12 to 1.54) and 1.22 (1.06 to 1.40), respectively. For RF+ RA, summary OR for ever, current and past smokers were 1.34 (0.99 to 1.80), 1.29 (0.94 to 1.77) and 1.21 (0.83 to 1.77). Summary OR for 20 or more pack-years of smoking was 1.75 (1.52 to 2.02). CONCLUSION Smoking is a risk factor for RA, especially RF+ RA men and heavy smokers.

Abstract
In inflammatory and oxidative liver injury, virus proteins and reactive oxygen species are involved in the regulation of proinflammatory cytokine production by macrophages. This study investigated the effects of estradiol (E2) and progesterone on the unstimulated and oxidative stress-stimulated production of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, macrophage inflammatory protein (MIP)-2, and macrophage chemotactic protein (MCP)-1 by peritoneal macrophages isolated from male and female mice. E2 inhibited the cytokine production of TNF-alpha, IL-1beta, MIP-2, and MCP-1 by the unstimulated macrophages from males and females, which was then further stimulated by progesterone. The exposure to hydrogen peroxide in the macrophages from both sexes induced the production of cytokine. The hydrogen peroxide-stimulated cytokine production was suppressed by E2 and enhanced by progesterone. The sex hormone effects on the unstimulated and stimulated macrophages were blocked by their receptor antagonists and showed no significant difference between male and female subjects. These findings suggest that E2 may play a favorable role in the course of persistent liver injury, by inhibiting proinflammatory cytokine production, which, in addition, progesterone may counteract the favorable E2 effects through their receptors.

Abstract
Accidental whole-body overexposure of radiation occurs very rarely. Radiation exposure causes DNA breaks in the cells and shows various clinical features, which are time dependent, dose dependent and tissue dependent. Neutron rays are more destructive than gamma rays but their actual effect on humans have been under-reported. We observed the time-dependent and the dose-dependent dermatological changes in a patient who was severely irradiated by neutron and gamma rays, with the aim of clarifying the clinicopathological features of severely irradiated skin. The detection of DNA breaks in keratinocytes was performed by the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labelling technique. The degenerative changes of the skin and the re-epithelialization varied in a time dependent and dose dependent manner. DNA breaks were significantly higher in irradiated keratinocytes. Neutron rays caused depth-dependent degeneration of the skin. Evaluation of DNA breaks in the skin cells might be a clue to estimate local dosimetry.

Abstract
AIM: To investigate the effects of estradiol (E2) and progesterone on the unstimulated and oxidative stress-stimulated production of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-8, and macrophage chemotactic protein (MCP)-1 by peripheral blood mononuclear cells (PBMCs) from patients with chronic hepatitis C and healthy controls.
METHODS: The PBMCs were separated from age-matched 72 males and 71 females with and without chronic hepatitis C, who were divided into two groups based on a mean menopausal age of 50 years. Oxidative stress was induced by hydrogen peroxide in the cells incubated in serum-free media. Cytokines in the culture supernatant were measured by an enzyme-linked immunosorbent assay.
RESULTS: The highest levels of the spontaneous production of TNF-α, IL-1β, IL-8, and MCP-1 by the unstimulated PBMCs were in the older male patients with chronic hepatitis C and the lowest levels were in the pre-menopausal female healthy controls. E2 inhibited the cytokine production by the unstimulated PBMCs from the older male and post-menopausal female patients, which was further stimulated by progesterone. The exposure to hydrogen peroxide in the PBMCs from the younger male and pre-menopausal female healthy subjects induced the production of cytokines. The change rates of the hydrogen peroxide-stimulated cytokine production were suppressed by E2 and enhanced by progesterone.
CONCLUSION: These findings suggest that E2 may play a favorable role in the course of persistent liver injury by preventing the accumulation of monocytes-macrophages and by inhibiting proinflammatory cytokine production, whereas progesterone may counteract the favorable E2 effects.

Abstract
The C242T polymorphism of p22phox, a component of NAD(P)H oxidase, may have an impact on cardiovascular diseases; however, the association between this polymorphism and brain infarction is not fully understood. Here, we investigate the relationship between the C242T polymorphism and brain infarction in Japan. We recruited 1055 patients with brain infarction and 1055 control subjects. A chi-squared test revealed that the T-allele frequency was lower in patients with cardioembolic infarction (5.6%) than in control subjects (11.0%, P < 0.001); however, allele frequencies in patients with lacunar and atherothrombotic infarction (11.2%) were not significantly different from those in control subjects (11.0%). A multivariate-adjusted conditional logistic regression analysis also revealed no association between CT + TT genotype, and lacunar and atherothrombotic infarction (odds ratio = 0.97, 95% confidence interval: 0.72-1.32). To investigate the functional effects of the C242T polymorphism, we examined superoxide production in COS-7 cells cotransfected with Nox4 and p22phox of each genotype. The superoxide-producing activity in those cells expressing p22phox with the T allele was not significantly different from that in cells expressing p22phox with the C allele. The present results suggest that the p22phox C242T polymorphism may have a protective effect against cardioembolic infarction, but is not related to lacunar and atherothrombotic infarction in Japan.

Abstract
BACKGROUND Autoimmune bullous diseases are characterized by autoantibodies against specific adhesion molecules of the skin and/or mucous membrane. While these autoantibodies are known to play a primary role in the disease manifestation, it remains unknown how disease-specific autoreactive B cells and autoantibodies are induced. Recent studies have indicated the importance of the CD40 and CD40 ligand (CD40L) receptor-ligand pair in the immunopathogenesis of autoimmune diseases. CD40L circulates in soluble form, and some reports suggest that serum soluble CD40L (sCD40L) levels are increased in various autoimmune diseases. OBJECTIVES To determine serum sCD40L levels in patients with pemphigus vulgaris (PV) and bullous pemphigoid (BP), and to determine their correlation with clinical findings and laboratory findings. PATIENTS AND METHODS Sera from 10 PV patients, 35 BP patients and 12 normal controls were subjected to ELISA assays to measure serum levels of sCD40L, anti-desmoglein-3 antibody and anti-BP180 antibody. RESULTS AND CONCLUSIONS Circulating sCD40L levels were significantly elevated in BP patients, but not in PV patients. Serum sCD40L levels increased in the early stage of disease onset and recurrence in BP patients. In conclusion, circulating sCD40L levels may be a useful marker for early activation of autoimmune diathesis and, furthermore, an effective therapeutic target in patients with BP.

Abstract
BACKGROUND Although chemokines play an important role in various inflammatory diseases, there have been few studies about the role of chemokines in alopecia areata (AA). OBJECTIVES To determine serum levels of chemokines in patients with AA and their clinical correlations. METHODS Serum samples from 85 patients with AA, 20 patients with atopic dermatitis, 20 patients with psoriasis vulgaris and 28 normal controls were examined by the cytometric bead array assay assessing monokine induced by interferon (IFN)-gamma (MIG), RANTES, interleukin-8 (IL-8), IFN-inducible protein-10, monocyte chemoattractant protein-1, macrophage inflammatory protein (MIP)-1alpha, MIP-1beta and eotaxin levels. Secreted chemokine levels from peripheral blood mononuclear cells (PBMC) of patients with AA were also investigated. RESULTS Serum MIG, RANTES, IL-8 and eotaxin levels were selectively increased in patients with AA compared with normal controls. Levels of MIG, RANTES and IL-8 secreted from PBMC of patients with AA were also increased. Furthermore, elevated serum MIG and RANTES levels significantly correlated with the disease activity. RANTES levels were nonsignificantly associated with a predisposition to atopy. CONCLUSIONS These results suggest that MIG and RANTES play an important role in the development of AA and are useful as markers of disease activity and as therapeutic targets.
