Although oxidative stress is the main pathophysiology of the development of diabetic neuropathy, oral administration of antioxidants has given disappointing results. Here, we hypothesized that local delivery of antioxidants would provide protective effects on Schwann cells due to the high concentration of local lesions. We prepared alpha-tocopherol (ATF)-loaded liposomes and tested their skin penetration after sonication. An in vitro study using IMS-32 cells was conducted to determine the level of reactive oxygen species (ROS) scavenging effects of ATF-liposomes. ATF reduced ROS in high-glucose-exposed IMS-32 cells in a dosedependent manner. ATF-liposomes also reduced the ROS level in vitro and ultrasound irradiation enhanced delivery to the dermis in porcine ear skin. This study showed that it is feasible to deliver ATF through the skin and can effectively reduce ROS. This model is worthy of development for clinical use.

The introduction of anti-amyloid therapies for Alzheimer’s disease (AD), such as lecanemab (Lequembi®), which was recently approved in Korea, necessitates careful monitoring for amyloid-related imaging abnormalities (ARIA) using brain MRI. To optimize ARIA monitoring in Korean clinical settings, the Korean Society of Neuroradiology (KSNR) and the Age and Neurodegeneration Imaging (ANDI) Study Group proposed MRI protocol recommendations on essential MR sequences, MRI acquisition parameters, timing and condition of MRI examinations, and essential details to provide a scientific basis for maximizing the safety and efficacy of AD treatment. A customized, standardized MRI protocol focusing on Korea’s healthcare environment can improve ARIA management and ensure patient safety through early detection of potential anti-amyloid therapy side effects, thereby enhancing treatment quality.

Objectives: The aim of this study is to identify the prevalence of parasuicide and deliberate suicide attempts in the general population of Korea, as well as their associations with sociodemographic risk factors and mental disorders. Methods: This study utilized data from the 2021 National Mental Health Survey of Korea. The survey was conducted between June and August 2021, involving 5,511 respondents aged 18 to 79 years living in communities. The Korean version of the Composite International Diagnostic Interview (K-CIDI) was used as the survey instrument. Logistic regression analysis was employed for statistical analysis. Results: The prevalence of parasuicide was 1.1%, and that of deliberate suicide attempts was 0.9%. The risk of parasuicide increased among younger age, while no significant associations with other sociodemographic factors were found.The risk of deliberate suicide attempts was associated with being divorced, separated or widowed and low income. Both parasuicide and deliberate suicide attempts were associated with depressive disorders, anxiety disorders, alcohol use disorders and nicotine use disorders. Conclusions The sociodemographic risk factors of parasuicide and deliberate suicide attempts are distinct. This study provides valuable insights into the mental disorder-related traits associated with parasuicide and deliberate suicide attempts, which could be useful in developing future suicide prevention programs.
