Abstract: Health state utilities are global measurements of quality of life and have been used to evaluate health outcomes for the cost-utility analysis. This study aimed to estimate the health state utilities of patients with hepatitis B (HB), hepatitis C (HC), and hepatitis-related diseases in Japan. We distributed a self-administered questionnaire, including the EuroQol 5-Dimension 5-Level (EQ-5D-5L), to 9,952 outpatients with several clinical conditions caused by HB or HC virus infection (such as asymptomatic chronic hepatitis, chronic hepatitis, compensated cirrhosis, and decompensated cirrhosis) and estimated the condition-specific utilities of patients with HB or HC. In patients with more severe conditions (patients with acute hepatitis, fulminant hepatitis, and hepatocellular carcinoma and patients undergoing post-liver transplantation), the utilities of these severe conditions were estimated by three hepatitis experts using the EQ-5D-5L. The means of the utilities for acute hepatitis, fulminant hepatitis, asymptomatic chronic hepatitis, chronic hepatitis, compensated cirrhosis, compensated cirrhosis, hepatocellular carcinoma stage I/II, hepatocellular carcinoma stage III/IV, and post-liver transplantation were 0.529, − 0.111, 0.904, 0.868, 0.845, 0.722, 0,675, 0,428, and 0.651 and 0.876, 0.821, 0.737, 0.671, 0.675, 0.428, and 0.651 in HB and HC, respectively. To the best of our knowledge, this is the first study that comprehensively assessed the health state utilities of patients with HB, HC and hepatitis-related conditions from a nationwide survey in Japan using the EQ-5D-5L.

Abstract: This study aimed to determine the characteristics of people who refrained from having regular checkups due to the spread of the novel coronavirus 2019 (COVID-19) infection and the factors associated with this behavior. We conducted a nationwide internet survey of 4593 males and females aged 20–69 in Japan regarding their health checkups from April 2020 to March 2021, when COVID-19 was widespread. In iduals who received checkups during this time were “the receiving group” those who did not were “the refraining group”. Personal attributes, responses to a health questionnaire and other items were used to compare the groups. The analysis showed that males over 53 refrained from having health checkups compared to those younger. On the other hand, males with higher personal incomes who never skipped breakfast received health checkups. Females with children under 18 years were less likely than those without to receive health checkups. For males, the characteristic factors were economic and health awareness and literacy. Females were less aware of medical checkups. Moreover, they demonstrated an inability to maintain an everyday rhythm. No factors were common to males and females, indicating the need to consider separate strategies for encouraging males and females to obtain annual health checkups.

Abstract: Background: The loss of E-cadherin expression and the induction of N-cadherin are known as hallmarks of the epithelial-to-mesenchymal transition, an essential initial step in the process of metastasis in solid tumors. Although several studies have reported expressions of these cadherins in patients with multiple myeloma (MM), their clinical significance is unknown as MM cells are non-epithelial. Methods: In this study, we examined the expression of E- and N-cadherins by immunohistochemistry using bone marrow (BM) biopsy specimens from 31 newly diagnosed MM patients and in subsequent biopsy specimens from six of these. Results: Negative E-cadherin expression on BM myeloma cell membranes was significantly associated with the presence of soft-tissue masses arising from bone lesions and breaking through the cortical bone, referred to as extramedullary disease (EMD). Conclusions: Given the aggressive nature of EMD, our study suggests that screening for E-cadherin using BM immunohistochemistry is one measure that could predict the development of EMD in patients with MM.
