Background: Impaired executive function is common in older adults. This study examined the causal relationship between the use of information and communication technology (ICT) and executive function in older adults over time.Method: This study performed a secondary analysis of data from four waves (2016–2019) of the National Health and Aging Trends Study. A fixed-effect analysis was conducted to examine the effects of ICT on the executive function of older adults without dementia aged ≥65 years. This study analyzed data from 3,334 respondents. Results: We observed significant positive effects of ICT use on executive function over time (standardized β=0.043–0.045; 95% confidence interval, 0.001–0.043; p<0.05). Conclusion The current findings support the use of ICT as a protective approach to prevent decline in executive function in community-dwelling older adults.

Objective: To evaluate human papillomavirus (HPV) vaccine effectiveness in a cohort of Korean women infected with HPV. Methods: From 2010 to 2021, Korean women aged 20–60 years who diagnosed HPV-positive atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion were recruited from 6 hospitals. HPV vaccine effectiveness was estimated by observing the differences in pathological and clinical information and experimental results— prevalence, viral load (VL), physical state (PS), and HPV16/18 infection duration—between the vaccinated and unvaccinated groups. Results: HPV16/18 prevalence declined from 18.5% to 11.8% as vaccination rates increased from 14.3% to 60.7% in the 1,757 registered cohort women. DNA analysis from 96 samples collected from the participants, indicated that HPV vaccination reduced HPV16 VL by 6 times and increased E2/E6 ratio for both HPV16 and HPV18 by 1.4 and 5 times, respectively. The HPV16 infection rate—lasting more than 18 months from 31.0% to 21.6%—and the HPV18 infection rate—lasting more than 12 and less than 24 months from 35.5% to 21.1%—were reduced by vaccination. We found VL and the infection duration to be directly proportional.Moreover, HPV vaccination reduced not only the VL to 1/4 in both the persistence and clearance groups but also the persistence rate from 90% (27/30) to 70.6% (12/17) in HPV16. Conclusion HPV vaccination reduced the prevalence and duration of infection and kept the PS in an episomal form for both HPV16 and HPV18. The tendency of persistence VL to be higher than clearance in the unvaccinated group implies that the vaccine’s effect of reducing VL in HPV16 may lower the risk of progression to cervical cancer by shortening the infection duration.

Purpose: The Korean Society of Medical Education (KSME) was founded in 1983 and celebrated its 40th anniversary in 2023. This study examines the evolution of topics discussed at KSME conferences from 1971 through 2023, highlighting shifts in the focus of medical education. Methods: We analyzed 90 KSME conferences over 5 decades (1970s, 1980s, 1990s, 2000s, and 2010s), categorizing the topics into three eras based on emerging themes and continuity. Results: Consequently, 37 topics covered at the conference were categorized. Ten topics continuously appeared from the 1970s to the 2010s, including future directions of medical education, teaching methods, faculty development, and curriculum. The topics from the 1970s to the 1990s included 14 areas, such as medical education evaluation, non-undergraduate curriculum, community-related, and research. Thirteen new topics emerged after the 2000s, such as social accountability, student support, professionalism, and quality improvements. The most common topics under innovations in medical education, a case of curriculum innovation at universities that began after 2000, were clinical clerkship, curriculum development, and medical humanities. Conclusion KSME’s selection of conference topics has been strategically aligned with societal needs and the evolving landscape of medical education. Future topics should continue to address relevant societal and educational challenges.

Interprofessional education (IPE) fosters knowledge, skills, and attitudes related to interprofessional collaboration (IPC) for safe, quality patient care. In recent years, the importance of IPC has extended beyond the medical field to local community settings. However, IPE has only recently been introduced and has yet to become widespread. This study reviews the origin and development of IPE in Korean medical education by comparing it with established models in other countries that provide useful insights into future directions for IPE in Korea. Dedicated institutions led the IPE effort in other countries; however, IPE initiatives in Korea were mainly driven by individual professors’ and medical schools’ interest and commitment, without structural support systems. An important finding of this study is that the lack of awareness and organizational support within the medical education community resulted in the absence of a mandatory curriculum for IPE, as it was omitted from the accreditation standards. For more organized adoption and implementation of IPE in Korea, this study suggests the need to widely communicate the importance of IPE to the medical community and the public. It is also imperative to establish leadership capable of guiding IPE, share materials through trusted institutions with IPE experience, and include IPE in the accreditation standards. These steps are essential for actively implementing IPE and meeting societal healthcare needs in Korea.

Background/Aims: There are limited studies on the management of hepatic hemangiomas (HHs). We investigated the proportion and predictors of surgical resection and analyzed HH growth rates in addition to associated factors. Methods: A retrospective case-control study of patients treated in 2 centers was conducted. Thirty-six patients who underwent surgical resection were assigned to the case group. Patients who did not undergo surgical treatment were randomly sigselected at a 1:10 ratio and assigned to the control group (n = 360). Baseline characteristics, clinical course and surgical outcomes were analyzed. Results: The proportion of surgically treated HH patients was 0.3% (36 per 11,049). The longest diameter at diagnosis (mean ± standard deviation) was 7.7 ± 5.2 cm in the case group and 2.4 ± 1.8 cm in the control group (p < 0.001). In the multivariate analysis, the presence of more than 2 HHs (odds ratio [OR] 7.64, 95% confidence interval [CI] 1.40–41.72) and a growth rate of more than 4.8%/year (OR 30.73, 95% CI 4.86–194.51) were independently associated with surgical treatment. Symptom development during follow-up was related to HH size > 10 cm (OR 10.50, 95% CI 1.06–103.77, p = 0.04). The subgroup analysis showed substantial growth in 41.3% with an overall mean annual growth rate of 0.14 cm. Conclusions Approximately one in 300 patients with an HH underwent surgical treatment. Multiple HHs and a growth rate of more than 4.8%/year were indications for surgical treatment. Nearly half of the HHs showed growing pattern in our study.

Medical history education enables the medical students to understand the humanistic aspects of medicine and also help to promote the professionalism of doctors. It makes them understand the disappearing or emerging diseases by recognizing the historical changes and trends to respond appropriately. Therefore, it is helpful to study and understand modern medicine.As of March 2023, 22 (55.0%) out of 40 medical schools in Republic of Korea have medical history course as an independent subject and two schools have integrated courses with medical ethics. Compared to 53.1% in 1995 and 56.2% in 2010, similar percentage of medical schools maintained the subject independently. However, the average credits of 18 schools in 2023(2.0) are higher than those of 1995(1.4) and 2010(1.2).The number of full-time professor who specialized in the history of medicine was 2 in 1995, 6 in 2010, and 11 in 2023. Generally, a full-time professor majoring medical history tend to have other duties besides the education and research of medical history, depending on the role of the department to which he or she belongs since they are assigned to the humanities education other than medical history education.Currently, the curriculums that have been recommended by Korea Association of Medical Colleges(KAMC), Korean Institute of Medical Education and Evaluation(KIMEE), and The Korean Society of Medical Education(KSMED), emphasize medical humanities but do not necessarily include the medical history. As a result, medical history courses have increased slightly, but the other humanities classes have increased significantly since 2000.The knowledge of medical history will help students become a doctor, and a doctor with professionalism adapting to the rapidly changing medical environment. Students will also be able to establish the ideas they must pursue in the present era when they come into contact with numerous historical situations. And if they share a sense of history, they will inspire a sense of unity as a profession and will be more active in solving social problems such as health equity.It is hoped that The Korean Society for the History of Medicine will step forward to set the purpose and goal of the medical history education, and organize the contents of the education. Classes should be prepared so that students are interested in them, and education should be focused on how the contents of education will be able to be used in medicine. To this end, it is necessary to establish the basic learning outcomes of history of medicine, and prepare learning materials based on these learning outcomes. It is also necessary to increase the competencies of educators for the history of medicine, such as performing workshops.With the dedication of the pioneers who devoted their energy to the education of medical history, it is expected that medical history will find out what to do in medical education to foster better doctors and provide better education.
