Objectives: We aimed to evaluate the performance of the optic disc-macula distance to disc-diameter ratio (DM/DD) in qualitative and quantitative assessment of optic disc size.

Methods: In 300 apparently normal eyes, we determined the correlation between DM/DD and the planimetric disc area (DA) and evaluated the performance of DM/DD in discriminating between small and large discs. The ability of DM/DD to predict the actual DA was validated in a separate cohort of 200 eyes.

Polymer-in-salt electrolytes were introduced three decades ago as an innovative solution to the challenge of low Li-ion conductivity in solvent-free solid polymer electrolytes. Despite significant progress, the approach still faces considerable challenges, ranging from a fundamental understanding to the development of suitable polymers and salts. A critical issue is maintaining both the stability and high conductivity of molten salts within a polymer matrix, which has constrained their further exploration.

Article Synopsis
  • The study investigates the outcomes of replantation surgery for amputated fingers in elderly patients (aged 65 and above) compared to younger patients, focusing on the feasibility of the procedure as more elderly individuals enter the workforce.* -
  • A cohort of 25 patients (12 elderly and 13 younger) who underwent successful finger replantation was analyzed over a follow-up period of more than one year, assessing key pinch strength, hand dexterity, and overall hand function.* -
  • Results indicated that while elderly patients performed worse on certain dexterity tests, their overall hand function post-surgery was similar to that of younger patients, suggesting that age alone should not deter finger replantation procedures in older adults.*

Background: Japan's stringent licensing policies for older drivers have not been questioned, possibly due to negative perceptions of older drivers potentially influenced by media coverage of their car crashes. We examined whether older drivers' fatal crashes are over-represented in the news articles.

Methods: To examine the news coverage of fatal crashes that occurred between January 2016 and December 2020, we extracted driver- and crash-related data from articles reporting fatal crashes in the two best-selling newspapers, Yomiuri and Asahi.
