AI Article Synopsis
- This study investigates how advanced glycation end-products (AGEs) in skin tissue relate to bone strength in healthy adult Japanese men.
- The findings reveal that higher levels of AGEs in skin correlate with a lower osteo-sono assessment index, suggesting weaker bones.
- This research highlights a potential link between AGE accumulation and bone health, emphasizing the need for further exploration in this demographic.
Article Abstract
Unlabelled: This study aims to determine the relationship between advanced glycation end-product (AGE) accumulation in skin tissue and bone strength, assessed by quantitative ultrasound, among healthy adult Japanese men. The results of the study suggest that men with higher AGE accumulation in skin tissue have a lower osteo-sono assessment index.
Introduction: AGE accumulate in bone collagen with age and diabetes and decrease the mechanical properties of bone. Although increased AGE levels are associated with fractures among diabetic patients and elderly women, it is unclear whether a relationship between increased AGE levels and bone strength is present in apparently healthy adult males. The aim of this study was to determine the relationship between AGE accumulation in tissue and the mechanical properties of bone among adult Japanese men, using quantitative ultrasound as a surrogate measure of the latter.
Methods: Skin autofluorescence (AF), which is a noninvasive method for measuring tissue AGEs, and osteo-sono assessment index (OSI), which is determined by quantitative ultrasound, were measured in 193 adult Japanese men (median age 43 years; interquartile range 37.0-55.0 years).
Results: Adjusted for age, BMI, calcium intake, physical activity, smoking status, and education level, log-transformed skin AF had a negative association with log-transformed OSI (β = -0.218, P < 0.01). Adjusted geometric means (95% CI) for OSI across the tertiles of skin AF were 2.81 (2.75-2.87) for the lowest tertile, 2.81 (2.74-2.87) for the middle tertile, and 2.66 (2.61-2.73) for the highest tertile; thus, OSI for the highest skin AF appeared to be 5.0% lower than that for the lowest and middle skin AF tertiles (P < 0.01).
Conclusion: Among apparently healthy adult Japanese men, those with higher skin AF had a lower OSI, indicating a relationship between AGE accumulation and bone strength. A long-term prospective study is required to clarify the causality.

Judges versus artificial intelligence in juror decision-making in criminal trials: Evidence from two pre-registered experiments.
PLoS One
January 2025
Center for International Education and Exchange, Osaka University, Suita, Osaka, Japan.
Background: Artificial intelligence (AI) is anticipated to play a significant role in criminal trials involving citizen jurors. Prior studies have suggested that AI is not widely preferred in ethical decision-making contexts, but little research has compared jurors' reliance on judgments by human judges versus AI in such settings.
Objectives: This study examined whether jurors are more likely to defer to judgments by human judges or AI, especially in cases involving mitigating circumstances in which human-like reasoning may be valued.
Assessing Caregiver Burden, Tasks, and Heart Rate Using Wearable Sensors: A Longitudinal Study of Informal Caregivers of Persons With Dementia and Older Adults.

Graduate School of Medicine, Mie University, Tsu, JPN.
Purpose In recent years, research on caregivers has highlighted the importance of integrating advanced technologies, such as wearable devices. Furthermore, when investigating the characteristics of persons with dementia (PWD), comparative analyses should be conducted based on the presence or absence of the condition. We aimed to elucidate the relationship between caregivers' subjective burdens, tasks, and heart rate (HR) using wearable sensors to objectively assess the health status of caregivers of PWD and older adults requiring long-term care.

Background: Japanese encephalitis (JE) is a zoonotic parasitic disease caused by the Japanese encephalitis virus (JEV), and may cause fever, nausea, headache, or meningitis. It is currently unclear whether the epidemiological characteristics of the JEV have been affected by the extreme climatic conditions that have been observed in recent years.
Objective: This study aimed to examine the epidemiological characteristics, trends, and potential risk factors of JE in Taiwan from 2008 to 2020.

Background: Many tools have been developed to predict the risk of diabetes in a population without diabetes; however, these tools have shortcomings that include the omission of race, inclusion of variables that are not readily available to patients, and low sensitivity or specificity.
Objective: We aimed to develop and validate an easy, systematic index for predicting diabetes risk in the Asian population.
Methods: We collected the data from the NAGALA (NAfld [nonalcoholic fatty liver disease] in the Gifu Area, Longitudinal Analysis) database.

Background: Myanmar is one of the countries in Southeast Asia where serious dengue outbreaks occur and Yangon is among the regions with the highest number of cases in the country. Many infections including dengue are common in Yangon during the rainy season, and co-infections may also occur. Adults are more likely than children to experience co-infections of dengue and other diseases.
