Background: Rural areas in Korea are experiencing both super-aging and depopulation, creating critical gaps in health and social care. Using a citizen participatory approach, we sought to address the care gaps for older adults in rural areas. This study examined the changes in frailty and depressive symptoms observed during a citizen-led intervention. Methods: This study is a single- arm pre–post quasi-experimental design. A 12-week intervention was implemented using local citizens as care providers. Intervention components included identifying and planning individual care needs, providing health education, organizing tailored community activities, and conducting AI-assisted weekly check-up calls to monitor health status. Results: Changes appeared more pronounced among vulnerable subgroups. Older adults with frailty showed an observed decrease in depressive symptoms compared to those with prefrailty or robust status. Conversely, among those with depressive symptoms, frailty levels appeared to increase more slowly than those without depressive symptoms. These patterns are consistent with the previously reported bidirectional associations between frailty and depression and may reflect the tendency for changes in one domain to coincide with changes in the other, rather than indicating a causal influence. Conclusion This citizen-led care intervention showed more noticeable short-term changes among older adults with higher vulnerability, particularly those with frailty or depressive symptoms. These findings indicate potential roles for citizen participation in enhancing social support and supporting ongoing monitoring in rural depopulation areas. The results suggest that citizen participation is a potentially feasible and sustainable approach to care systems in aging, resource-limited communities.

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.

Purpose: This study aimed to develop reimbursement models for advanced practice nurses (APNs) in Korea by analyzing APN workload, estimating optimal patient-to-APN ratios, and calculating APN employment costs. Methods: A descriptive study was conducted with 116 APNs working from general wards and intensive care units (ICUs) at three tertiary hospitals. Data were collected from March to May 2025 using structured questionnaires and activity diaries. APN workload was classified into 15 task categories comprising 79 sub-activities and additionally unclassified miscellaneous activities. Time spent per patient was used to estimate optimal patient loads, and employment costs were calculated using salary and administrative expense data. Daily reimbursement per patient was derived by dividing operating costs by the optimal caseload. Results: Participants were predominantly female (99.1%), with a mean age of 38.9 years and an average of 15.9 years of clinical experience.APNs devoted the greatest share of their time to patient assessment and prescription-related activities. The optimal patient load was 10~15 per APN in general wards and 5~10 in ICUs. Based on these workload-derived ratios, the estimated reimbursement ranged from KRW 12,333 to 114,659 per patient per day in general wards and KRW 49,330 to 229,318 per patient per day in ICUs. Conclusion By linking workload, staffing needs, and employment costs, this study offers an empirical foundation for designing equitable APN reimbursement models.These findings support policy efforts to secure appropriate APN compensation, enhance workforce stability, and strengthen team-based care. Implementation through pilot reimbursement programs is recommended to evaluate their feasibility and economic impact.

The worldwide incidence of precocious puberty, which is associated with negative health outcomes, is increasing. Several studies have suggested that environmental factors contribute to the development of precocious puberty alongside genetic factors. Some epidemiological studies have provided limited evidence suggesting an association between exposure to air pollution and changes in pubertal development. This systematic review aimed to summarize existing evidence on the association between air pollution exposure and precocious puberty. Following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, we searched two databases (PubMed and Web of Science) until August 2023. The included studies assessed the association between air pollutant exposure and the risk of precocious puberty, early menarche, or pubertal development. Two authors independently performed study selection and data extraction. A meta-analysis and analysis of the risk of bias were infeasible due to the limited number of studies and the heterogeneity among them. The literature search resulted in 184 studies, from which we included six studies with sample sizes ranging from 437 to 4,074 participants. The studies reported heterogeneous outcomes. Four studies found that increased exposure to air pollution was related to earlier pubertal onset. One study was inconclusive, and another suggested that air pollutant exposure may delay the onset of thelarche. Most studies suggest that exposure to air pollutants accelerates pubertal development; however, the results from the available studies are inconsistent. More extensive and well-designed longitudinal studies are required for a comprehensive understanding of the association between air pollution and precocious puberty.

Background: and Purpose The description of pain is the most-important indicator leading to the adequate treatment of patients with neuropathic pain (NeP). The purpose of this study was to identify and characterize the unique features of Korean verbal descriptions in patients with peripheral NeP. Methods: This study included 400 patients (167 males and 233 females) and their 1,387 paindescription responses. Patients with peripheral NeP freely described their symptoms in Korean. Collected verbal descriptions were grouped according to terminologies with similar meanings. Participants completed validated patient-reported outcome scales including the neuropathic pain symptom inventory (NPSI) and painDETECT questionnaire (PD-Q). The frequencies of each verbal pain descriptor were compared between the NPSI and PD-Q scores. Results: ‘Jeorim’ (tingling) was the most common among 17 types of organized verbal pain descriptors, and the ‘Sirim’ (cold) symptom had a significantly higher rate of use in the 2 highseverity groups when participants were classified by their total scores on the NPSI and PD-Q. Conclusions Korean verbal NeP descriptors were significantly diverse. The Jeorim (tingling) and Sirim (cold) descriptors can be utilized in evaluations of Korean patients with NeP.

Objectives: Ewha Womans University launched an on-campus Coronavirus disease-19 (COVID-19) response system called Ewha Safety Campus (ESC) Project in collaboration with the Seegene Inc. RTPCR diagnostic tests for COVID-19 were proactively provided to the participants. This study examines the effectiveness of the on-campus testing strategy in controlling the reproduction number (Rt ) and identifying student groups vulnerable to infection. Methods: The ESC project was launched on March 2, 2022, with a pilot period from Feb 22 to March 1, 2022—the peak of the Omicron variant wave. We collected daily data on the RT-PCR test results of the students of Ewha Womans University from Mar 2 to Apr 30, 2022. We daily calculated Rt and compared it with that of the general population of Korea (women, people aged 20–29 years, and Seoul residents). We also examined the students vulnerable to the infection based on the group-specific Rt and positivity rate. Results: A lower Rt was observed about 2 weeks after the implementation of the ESC Project than that of the general population. The lower Rt persisted during the entire study period. Dormitory residents had a higher Rt . The positivity rate was higher in students who did not comply with quarantine guidelines and did not receive the second dose of the vaccine. Conclusion The study provides scientific evidence for the effectiveness of the on-campus testing strategy and different infection vulnerabilities of students, depending on dormitory residence, compliance with the quarantine guidelines, and vaccination.

We report a case of a 75-year-old woman who was diagnosed with dermatomyositis presenting with isolated dysphagia. There were no obvious cranial nerve deficits with normal motor grade in all the limbs in neurological examinations, but a suspicious rash was observed in the anterior chest. The serum creatine kinase was 306 IU/L, and active myopathic changes in bilateral limb muscles were observed in the electromyography test. Muscle biopsy from vastus lateralis showed perivascular infiltration of mononuclear inflammatory cells, which was compatible with dermatomyositis. She had responded to oral prednisolone and azathioprine.

In response to the changes in the Coronavirus disease 2019 (COVID-19) epidemic situation, Ewha Womans University established Ewha Safe Campus (ESC), an on-campus infection outbreak management system, to allow students and faculty members to safely resume face-to face classes in 2022. The COVID-19 testing station, Ewha Safe Station, is the core element of ESC. Symptomatic students and faculty members perform a combo swab self-PCR test or receive a nasopharyngeal swab PCR test from experts to prevent the spread of COVID-19 through early detection and management. ESC is significant in that it detects infection risks and proactively implements preemptive measures in a university. The COVID-19 health response system model at the university level was applied for the first time in South Korea, reaching a milestone in the history of university health in South Korea. In particular, it is highly valuable that the test was free of charge, as it enabled all of the examinees to have easy access to the test through joint cooperation with the Seegene Medical Foundation. This is a successful example of cooperation between schools and private institutions for public health improvement. In the future, the direct and indirect effects of the establishment and implementation of ESC need to be evaluated and confirmed, and areas requiring improvements need to be identified in preparation for another infectious disease outbreak in the future.
