Open AIDS Journal 17 2023年Background: Most hemophiliacs living with HIV are co-infected with HCV. In their clinical practice, the long-term effects of anti-HIV and anti-HCV therapies have not been sufficiently investigated. Objective: This study aimed to evaluate changes in HIV RNA and HCV RNA levels and the prognosis in hemophiliacs living with HIV over 24 years in Japan. Methods: We used cohort study data of 578 hemophiliacs living with HIV. We analyzed trends in HIV RNA levels between the fiscal years 1997 and 2008 (first follow-up), and trends in HIV RNA and HCV RNA levels between the fiscal years 2009 and 2020 (second follow-up). Mortality rates by HIV RNA and HCV RNA levels were calculated from 11,207 observed person-years and 194 deaths. Results: The percentage of HIV RNA levels <400 copies/mL rose in the first period of follow-up, and the percentage of HCV RNA-negative rose in the second period of follow-up. The participants with HIV RNA levels <400 copies/mL had a significantly lower mortality rate than the others, with a ratio of 0.46 in the first period. HCV antibody-positive participants who were HCV RNA-negative had a significantly lower mortality rate than those who were HCV RNA-positive, with a ratio of 0.47 in the second period. Conclusion: After the introduction of combination anti-HIV therapy over 24 years in hemophiliacs living with HIV, HIV RNA levels decreased in the first half of this period, resulting in decreased mortality. Additionally, HCV RNA levels decreased in the second half of this study period, resulting in even further decreased mortality.

Diagnostics (Basel, Switzerland) 12(12) 2022年12月12日The predominant histological subtype of breast mucinous carcinoma in older women is type B (hypercellular type), and, in younger women, it is type A (hypocellular type). The characteristics of mucinous carcinomas of the same histological subtype may differ between older and younger women. This study aims to systematically clarify the pathological/immunohistochemical features of mucinous carcinomas. A total of 21 surgical cases of mucinous carcinoma (type A/B: 9/12 cases) in the older group (≥65 years) and 16 cases (type A/B: 14/2 cases) in the younger group (≤55 years) (n = 37) were included. Gross cystic disease fluid protein-15 (GCDFP-15) and eight other markers were used for immunostaining. The GCDFP-15-positive rate in the older group was high regardless of the histological subtype (type A, 77.8%; type B, 91.7%). The GCDFP-15 positivity in the older group was significantly higher than that in the younger group (p < 0.001 for Allred score). Among type A, GCDFP-15 positivity was significantly higher in the older group than in the younger group (p = 0.042 for the Allred score and p = 0.007 for the positivity rate). The present results suggest that GCDFP-15 expression characterizes mucinous carcinomas in older women.

移植 52(2-3) 113-133 2017年9月<p>A large number of 1,648 kidney transplants in Japan, including 1,471 from living donors, 61 from nonheart-beating donors, and 116 from heart-beating donors, were performed in 2016.<br/>The data obtained from the Japanese Renal Transplant Registry are shown and analyzed in this annual report. The characteristics of recipients and donors, such as relationships, original diseases, duration of dialysis therapy, blood transfusion, status of viral antigens and antibodies, pretransplant complications, causes of death of deceased donors, ischemic time, and histocompatibilities, are described. Moreover, immunosuppressants used initial and other treatments are analyzed.<br/>We also report the results of a follow-up survey for recipients and living donors.</p>
