Two complete dog skeletons were recovered during archeological excavations from 1961 to 1970 at the Kamikuroiwa rock shelter, a site that yielded a series of cultural entities from the Late Pleistocene, Incipient Jomon, and Early Jomon periods. Since two dogs were buried close to human skeletons, it was thought that these dogs had been buried by Jomon people, and hence provided the oldest direct evidence of Canis domestication in Japan. However, the stratigraphic information and archeological contexts of these dog skeletons are incomplete due to the lack of detailed excavation reports and technical limitations of excavations at this site. Because the date of the dog burials has not been fully discussed in the context of modern chronology or recent discussions on Canis domestication, we directly measured radiocarbon ages and stable isotope analysis on two dog burials and one set of human remains from the Kamikuroiwa rock shelter. These data are important for reconstructing the relationship between humans and dogs in the Jomon period. Our results show that the human thought to have been buried with the dogs was assigned to the middle Initial Jomon period (8977–8725 calBP), whereas, on the other hand, dates for the dog burials are very close to each other and were assigned to the latest Initial Jomon or the initial Early Jomon periods (7414–7273 calBP). Although these results are not consistent with previous archeological interpretations for this site, they remain important because these two dog burials are among the oldest evidence of Canis domestication in East Asia.

A 5-year multicenter retrospective cohort study was conducted across six hospitals in Niigata, Japan. Patients (n = 179) with bacteremia due to extended-spectrum β-lactamase (ESBL)producing organisms were included in the study. The rates of appropriate carbapenem prescription were 61% (n = 41) in patients aged 65–84 years and 89% (n = 31) in those aged ≥ 85 years. Patients aged ≥ 85 years were significantly more likely to receive carbapenem than their younger counterparts. After propensity score matching, 65 patients were assigned to two groups based on age (65–84 years or ≥ 85 years). Multivariate regression analysis showed that other sites of infection had a positive association with 30-day mortality (odds ratio [OR], 27.50; 95% confidence interval [CI], 2.90–260.00) and biliary tract infection tended to have a positive association with 30-day mortality (OR, 8.90; 95% CI, 0.88– 89.90) compared with urinary tract infection. However, an age ≥ 85 years was not associated with 30-day mortality. Elderly patients aged ≥ 85 years were more likely to be treated with carbapenem; however, old age was not associated with 30-day mortality when bacteremia was caused by ESBLproducing organisms. These results may help clinicians justify withholding carbapenem in patients aged ≥ 85 years.
