OBJECTIVE Aging of the population may lead to epidemiological changes with respect to chronic subdural hematoma (CSDH). The objectives of this study were to elucidate the current epidemiology and changing trends of CSDH in Japan. The authors analyzed patient information based on reports using a Japanese administrative database associated with the diagnosis procedure combination (DPC) system. METHODS This study included patients with newly diagnosed CSDH who were treated in hospitals participating in the DPC system. The authors collected data from the administrative database on the following clinical and demographic characteristics: patient age, sex, and level of consciousness on admission; treatment procedure; and outcome at discharge. RESULTS A total of 63,358 patients with newly diagnosed CSDH and treated in 1750 DPC participation hospitals were included in this study. Analysis according to patient age showed that the most common age range for these patients was the 9th decade of life (in their 80s). More than half of patients 70 years old or older presented with some kind of disturbance of consciousness. Functional outcomes at discharge were good in 71.6% (modified Rankin Scale [mRS] score 0-2) of cases and poor in 28.4% (mRS score 3-6). The percentage of poor outcomes tended to be higher in elderly patients. Approximately 40% of patients 90 years old or older could not be discharged to home. The overall recurrence rate for CSDH was 13.1%. CONCLUSIONS This study shows a chronological change in the age distribution of CSDH among Japanese patients, which may be affecting the prognosis of this condition. In the aging population of contemporary Japan, patients in their 80s were affected more often than patients in other age categories, and approximately 30% of patients with CSDH required some help at discharge. CSDH thus may no longer have as good a prognosis as had been thought.

Cardiovascular Disease With Hormone Therapy and Ovarian Suppression in Premenopausal Breast Cancer Survivors.

JACC CardioOncol

December 2024

Division of Epidemiology and Community Health, School of Public Health, University of Minnesota, Minneapolis, Minnesota, USA.

Background: Hormone therapies, including aromatase inhibitors and tamoxifen, are used with ovarian suppression to improve outcomes in premenopausal patients with breast cancer. Cardiovascular impacts of these treatments among premenopausal women are unknown.

Objectives: The aim of this study was to test the hypothesis that the use of aromatase inhibitors in combination with ovarian suppression, relative to tamoxifen, is associated with greater incident cardiovascular disease (CVD) risk in premenopausal breast cancer survivors.

The increasing use of real-world evidence (RWE) and real-world data (RWD) to assess post-market medical devices (MDs) might satisfy the urgent need for data sharing and traceability. This study sought to (i) get an overview of current practice in post-market assessments of MDs reporting on RWE/RWD; (ii) draw policy recommendations for governments and health organisations and identify a research agenda for scholars.A systematic review was undertaken until February 2024 following the PRISMA guidelines.
