Background: The need for support focused on frailty and quality of life (QoL) in older adults is increasing. The Kihon Checklist (KCL) is a comprehensive and easy-to-use tool to assess frailty in older adults. Previous studies have shown associations between frailty and QoL; however, few studies have investigated the association between frailty using the KCL and QoL. In this study, the quantitative relationship between the KCL and QoL in community-dwelling older adults was investigated. Methods: This cross-sectional study included from participants in the 2017–2019 baseline survey of a cohort study of community-dwelling older adults in Sapporo, Japan. The World Health Organization-Five Well-Being Index (WHO-5) was used to assess QoL. The KCL was used to assess frailty, and the relationship between frailty and QoL was examined using binomial logistic regression analysis and restricted cubic spline models. Results: Four-hundred participants were included in the analysis. Of the participants, 22.5% had a lower QoL and they were more likely to have frailty than healthy participants (p<0.001). The KCL scores were significantly associated with a lower QoL (p<0.001). Furthermore, the association between the KCL score and QoL was linear, and subscales of activities of daily living, and depressive mood were significantly associated with a lower QoL. Conclusion The KCL, a comprehensive frailty questionnaire, was associated with a lower QoL in older adults. To maintain QoL in community-dwelling older adults, it is necessary to provide them with appropriate support from the stage before they are identified as frail by the KCL.

Background: Residual tricuspid regurgitation has recently been recognized as an adverse prognostic factor, for which reliable regurgitation control is required. Tricuspid valve repair with ring annuloplasty is the most common procedure for tricuspid regurgitation. However, if the rings are severely enlarged or the valves are strongly tethered by enlarged right ventricles, it is difficult to control the regurgitation by annuloplasty procedure only. The complex valvuloplasty procedures as required for mitral valve surgery are sometimes needed for these severe cases. Although tricuspid valve replacement (TVR) is sometimes chosen for simple and reliable regurgitation control in such cases, the procedure is uncommon and the long-term outcomes have yet to be clearly identified. In this study, the results of 17 TVR cases at our clinic are reviewed. Patients and Methods: Seventeen patients underwent TVR between February 2008 and May 2022. The operative outcomes and the echocardiographic changes of the implanted prosthetic valves were then retrospectively studied. Results: All the patients had implanted Carpentier-Edwards pericardial valves. Hospital mortality occurred in two cases. Among the survivors, three patients underwent re-operations for prosthetic valve dysfunction. One patient underwent tricuspid valvuloplasty using the Inoue balloon catheter, while the other two underwent re-tricuspid valve replacement using prosthetic tissue valves. The explanted valves showed severe adhesion between the leaflets and around the tissue, such as the patient's own remaining tricuspid valves or the right ventricular organs. The timings of the re-operations were 6 to 8 years after the first TVR. Prosthetic valve function was studied by color Doppler echocardiography. Follow-up data were available only for twelve patients. Prosthetic valve regurgitation steadily worsened approximately three years after the operation, and the mean transprosthetic gradient gradually increased about 1.5 times in four years after implantation. These results suggest that the Carpentier-Edwards pericardial valve in the tricuspid position may begin to deteriorate in 3 to 4 years. Conclusion: The surgical outcomes of TVR with the Carpentier-Edwards pericardial valves are not satisfactory.

A 78-year-old man presented with back pain 20 years after aortic root replacement using a homograft and was admitted with a diagnosis of pyogenic spondylitis. The patient had a history of prosthetic valve infective endocarditis (PVE) 9 months after aortic valve replacement (AVR) at 57 years of age at another hospital, and had undergone aortic root replacement using a homograft. Streptococcus anginosus was detected in blood culture, and antibiotic therapy was commenced according to the treatment of PVE. During the course of the treatment, the diagnosis of PVE was confirmed due to worsening aortic regurgitation (AR) and a finding of suspected vegetation attachment to the right coronary cusp. Since there were no embolic symptoms or heart failure, antibiotic therapy was preceded by surgery on the 33rd day. Intraoperatively, the homograft showed a highly calcified sinus of Valsalva and each valve leaflet was very fragile. The aortic valve had a vegetation adherent to the tip of the right coronary leaflet, but the infection was localized and did not extend to the annulus. Although aortic root replacement had been considered, the patient was elderly and had impaired activities of daily living, so AVR was performed in order to reduce the invasiveness of the procedure. The annulus was so hard that the needle could not be passed through. It was possible to thread the annulus by inserting the needle through the autologous tissue below the suture line on the proximal side of the homograft at the previous surgery. A bovine pericardial patch was used to close the aortotomy line of sclerotic homograft. There was no recurrence of infection, and the patient was transferred to the hospital for rehabilitation on postoperative day 37. The optimal surgical technique should be considered according to the degree of calcification and the patient's background in each case, as grafts are often highly calcified in cases of reoperation after homograft replacement.

Objective: In this study, we collected data over 8 years (2012–2019) from the Japan Society of Obstetrics and Gynecology (JSOG) tumor registry to determine the status of endometrial cancer in Japan, and analyzed detailed clinicopathological factors. Methods: The JSOG maintains a tumor registry that gathers information on endometrial cancer treated at the JSOG-registered institutions. Data from the patients whose endometrial cancer treatment was initiated from 2012 to 2019 were analyzed retrospectively. Results: A total of 82,969 patients with endometrial cancer underwent treatment from 2012 to 2019. Chemotherapy alone or in combination with hormonal therapy is more common among endometrial cancer patients under 40 years compared with those over 40 years. The number of patients with endometrial cancer, treated with laparoscopic or robot-assisted surgery was observed to have increased yearly. Small cell carcinomas and undifferentiated carcinomas were more likely to be diagnosed at an advanced stage. Lymphadenectomy was most commonly performed for stage IIIC2 disease, whereas positive peritoneal washing cytology was most common for stage IVB and serous carcinoma. Conclusion Multi-year summary reports provided detailed clinicopathological information regarding endometrial cancer that could not be obtained in a single year. These reports were useful in understanding treatment strategies and trends over time based on age, histology, and stage.

Objective: To evaluate the long-term efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer. Methods: This was the follow-up analysis of a phase 2, multicenter, open-label, single-arm study in Japanese women with homologous recombination-deficient, platinum-sensitive, relapsed, high-grade serous epithelial ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of chemotherapy and were poly(ADP-ribose) polymerase inhibitor naïve. Participants received niraparib (starting dose, 300 mg) once daily in continuous 28-day cycles until objective disease progression, unacceptable toxicity, or consent withdrawal. The primary endpoint was confirmed objective response rate (ORR), as assessed using Response Evaluation Criteria in Solid Tumors version 1.1. Safety evaluations included treatment-emergent adverse events (TEAEs). Results: 20 patients were enrolled in the study and included in both efficacy and safety analyses. Median total study duration was 759.5 days. Median dose intensity was 201.3 mg/ day. Confirmed ORR was 60.0% (90% confidence interval [CI]=39.4–78.3); 2 patients had complete response and 10 patients had partial response. Median duration of response was 9.9 months (95% CI=3.9–26.9) and the disease control rate was 90.0% (95% CI=68.3–98.8).The most common TEAEs were anemia (n=15), nausea (n=12), and decreased platelet count (n=11). TEAEs leading to study drug dose reduction, interruption, or discontinuation were reported in 16 (80.0%), 15 (75.0%), and 2 patients (10.0%), respectively. Conclusion The long-term efficacy and safety profile of niraparib was consistent with previous findings in the equivalent population in non-Japanese patients. No new safety signals were identified.
