Persistent excess mortality in post-pandemic Japan
More than six years after the emergence of COVID-19, Japan continues to experience persistently elevated excess mortality despite entering a post-pandemic phase. Excess mortality, defined as the difference between observed and expected deaths, reflects both direct and indirect effects of the pandemic, including healthcare disruption, delayed care, and broader social changes. In Japan, mortality decreased slightly in 2020 but increased markedly fr…
Age-specific patterns of all-cause mortality across Covid-19 booster dose groups in two Japanese municipalities
Background/purpose: COVID-19 mRNA vaccines have been reported to reduce severe COVID-19 outcomes in high-risk populations. In Japan, booster vaccinations up to the seventh dose are publicly funded; however, evidence regarding the safety and potential benefits of repeated booster doses in younger adults remains limited. This exploratory observational study aimed to describe age-specific patterns of all-cause mortality according to the number of CO…
Association between Physical Frailty Subdomains and Oral Frailty in Community-Dwelling Older Adults
This cross-sectional study aimed to demonstrate the association between physical frailty subdomains and oral frailty. This study involved community-dwelling older adults (aged ≥65 years). Physical frailty was assessed with the Japanese version of the Cardiovascular Health Study criteria. Oral frailty was defined as limitations in at least three of six domains. Logistic regression analysis was used to analyze the association between physical frail…
A comparative study on testicular microstructure and relative sperm production in gorillas, chimpanzees, and orangutans
We performed histological analyses for comparing testicular microstructure between the gorilla, chimpanzee, and orangutan. Testicular samples were obtained by autopsy or biopsy from 10 gorillas, 11 chimpanzees, and 7 orangutans from several zoos and institutes. The seminiferous epithelia were thick in the chimpanzee and orangutan but thin in the gorilla. Leydig cells in the interstitial tissue were abundant in the gorilla. The acrosomic system wa…
Testicular histological examination of spermatogenetic activity in captive gorillas ( Gorilla gorilla )
To clarify the reproductive state of male gorillas, we performed histological examinations on the testicles of 10 male gorillas ( Gorilla gorilla ). The testicular samples were obtained by autopsy, and ordinal histological preparations were made for light microscopy. The poor spermatogenesis of this species was characterized by the following findings: First, spermatogenesis was evident in only four samples. Meiosis progressed in two samples, but …
