Purpose:
This study aimed to investigate the relationship between body composition and glaucoma by analyzing the associations between anthropometric and ocular parameters.
Methods:
A total of 494 eyes from 247 patients were reviewed from a general health examination database at a tertiary hospital. Anthropometric parameters were assessed using a multifrequency bioelectrical impedance device. Mean ocular perfusion pressure (MOPP) was calculated based on systolic and diastolic blood pressures and intraocular pressure (IOP). Retinal thickness and other ocular parameters were analyzed for their association with body composition.
Results:
A total of 221 eyes from 221 patients, including 104 with glaucoma, were enrolled in the final analysis. The prevalence of sarcopenia was significantly higher in patients with glaucomatous damage than in those without (p = 0.025). Higher IOP showed significant associations with lower MOPP (p < 0.001), higher body mass index (BMI; p = 0.001), and higher waist to hip ratio (p = 0.001). Retinal thickness was not significantly associated with body composition parameters, including BMI and appendicular lean mass adjusted with squared height. Higher MOPP was significantly correlated with lower IOP (p < 0.001), higher BMI (p < 0.001), higher waist to hip ratio (p < 0.001), and higher appendicular lean mass divided by squared height (p = 0.009).
Conclusions
Skeletal muscle mass and BMI were significantly associated with MOPP. Since low MOPP is a known risk factor for glaucoma, its association with skeletal muscle mass may indicate a relationship between systemic muscle health, ocular blood perfusion, and glaucomatous damage. Further large-scale studies are needed to validate these associations between skeletal muscle mass and glaucoma and explore their clinical implications.

The peer review process ensures the integrity of scientific research. This is particularly important in the medical field, where research findings directly impact patient care. However, the rapid growth of publications has strained reviewers, causing delays and potential declines in quality. Generative artificial intelligence, especially large language models (LLMs) such as ChatGPT, may assist researchers with efficient, high-quality reviews. This review explores the integration of LLMs into peer review, highlighting their strengths in linguistic tasks and challenges in assessing scientific validity, particularly in clinical medicine. Key points for integration include initial screening, reviewer matching, feedback support, and language review. However, implementing LLMs for these purposes will necessitate addressing biases, privacy concerns, and data confidentiality. We recommend using LLMs as complementary tools under clear guidelines to support, not replace, human expertise in maintaining rigorous peer review standards.

Korean Journal of Medicine 2024;99(6):315-321
Background:
s/Aims: The recent increase in medical school admissions has potentially altered the working conditions of hospitalists in South Korea. This study investigated how these changes have affected the work patterns and responsibilities of hospitalists, particularly in light of the ongoing exodus of medical trainees that began on February 22, 2024.
Methods:
We surveyed members of the Korean Society of Hospital Medicine and the Korean Society of Surgery Hospital Medicine Study Group working as hospitalists from April 2 to 30, 2024. The survey was conducted via email and excluded personally identifiable information. Respondents’ characteristics, work types, hours, patient loads, support staff availability, and changes in job scope post-policy were analyzed.
Results:
Sixty-three hospitalists responded, with an equitable gender distribution and a median age of 39 years. A significant shift in work patterns was noted, with full-day shifts increasing from 22.2% to 39.7%, and a corresponding decrease in weekday daytime shifts. Work hours also significantly increased from a median of 40 to 45 hours per week. Changes in patient distribution were observed, with fewer hospitalists managing mid-range patient numbers and more handling smaller or larger loads. Despite the increased demands in the latter case, more than 50% of hospitalists reported a lack of support staff and a significant portion did not receive overtime compensation.
Conclusions
The increase in medical school admissions and subsequent shifts in hospitalist workloads and hours indicate a strained healthcare system. Hospitalists are taking on more intensive and extended roles. The absence of adequate support staff and adjustments in compensation suggest that further systemic changes are necessary to sustain the efforts of hospitalists, thereby ensuring patient safety and care quality.
