This study aims to develop a standardized informed consent system for whole-genome sequencing (WGS)-based newborn screening (NBS) in Korea through a policy design approach grounded in the domestic legal and policy context. We conducted an integrated literature review of international norms, domestic legal frameworks, guidelines, and major overseas WGS-based NBS programs using a common analytical framework. To develop a consent model feasible in the Korean context, we also analyzed stakeholder evidence from parent interviews and a clinician survey focused on consentrelated issues. The findings indicate that the current Korean legal and institutional framework does not adequately address long-term storage, reanalysis, recontact, and the transfer of decision-making authority as the child matures. Based on these findings, we propose a Korean informed consent model consisting of a staged consent pathway spanning antenatal, postnatal, and adulthood-related decision points; tiered consent options for the return of results; and safeguards against disadvantage or discrimination related to participation, non-participation, or withdrawal. The study further suggests that implementation will require broader legal and procedural clarification across the relevant regulatory framework, along with the continued development of education and counseling strategies.

Myopia, particularly high myopia, is a significant risk factor for several ocular pathologies including cataract, glaucoma, and retinal detachment. Excessive axial elongation associated with high myopia can induce biomechanical stretching, increasing the risk of serious complications like posterior staphyloma and myopic maculopathy. Global meta-analyses estimate that approximately 10 million people were visually impaired due to myopic maculopathy in 2015, with 3 million being blind. Recent nationwide surveys in South Korea revealed a prevalence of 65.4% for myopia and 6.9% for high myopia in children and adolescents, highlighting the urgent need for effective management. Delaying the onset and slowing the progression of myopia during childhood and adolescence is crucial for reducing the potential lifetime risk of these complications. This consensus statement, prepared by the Korean Myopia Society for the Korean Association for Pediatric Ophthalmology and Strabismus (KAPOS), reviews the current evidence for myopia control interventions and provides management strategies applicable to the South Korean clinical setting. Key interventions covered include lifestyle modifications (outdoor time, near work adjustment), optical methods (myopia-control spectacle lenses, dual-focus soft contact lenses, orthokeratology), and pharmacologic treatment (low-concentration atropine), as well as combination therapies. The statement also addresses patient selection, treatment outcome evaluation using spherical equivalent and axial length changes, and the crucial aspects related to treatment cessation and the rebound effect.

Background/Aims: Helicobacter pylori is a pathogen that causes chronic gastritis and peptic ulcer diseases and is a carcinogen responsible for the development of malignancies, including gastric cancer. In the current era of high antimicrobial resistance, rifabutin-based triple therapy is recommended as a salvage therapy. Bismuth has not only a strong bacteriostatic effect but also a synergic effect when combined with antibiotics. Our study aimed to compare and evaluate the eradication rates between rifabutin-based triple therapy and rifabutin with bismuth-containing quadruple therapy as salvage treatments. Methods: In this single-center study, patients who received rifabutin-based triple therapy and rifabutin with bismuth-containing quadruple therapy after failure of conventional therapy, including first- and second-line treatment, between January 2016 and July 2024, were retrospectively investigated. A total of 53 patients who received rifabutin-based triple therapy and 50 who received bismuth-containing quadruple therapy were included. Results: In the rifabutin-based triple therapy group, eradication was achieved in 32 out of 53 patients (60.4%; 95% confidence interval [CI], 46.8% to 74.0%). In the bismuth-containing quadruple therapy group, eradication was achieved in 40 out of 50 patients (80.0%; 95% CI, 68.5% to 91.5%), demonstrating significant therapeutic benefit (p=0.030). Adverse events, including nausea, epigastric discomfort, and lethargy, were significantly more frequent in the bismuth-containing quadruple therapy group (p=0.007), but they were mild and tolerable enough not to affect compliance (p=0.329). Conclusions Rifabutin with bismuth-containing quadruple regimen as a salvage treatment achieved significantly superior eradication efficacy over the rifabutin-based triple regimen. Further multicenter prospective studies are needed to provide additional supporting evidence.

OBJECTIVES

The COVID-19 pandemic has exacerbated burnout among medical students, impacting their academic performance and well-being. Resilience, a protective factor against burnout, remains understudied in the context of blended learning for medical students. This study aimed to examine the correlation between resilience and burnout dimensions (emotional exhaustion, cynicism, and academic efficacy) among first- to third-year medical students at a private medical institution during the 20222023 academic year.

A correlational design was employed, utilizing the Connor-Davidson Resilience Scale-10 (CDRISC-10) and the Maslach Burnout Inventory-General Survey for Students (MBI-GS (S)). Sixty participants were randomly selected from the first-year to third year medical students .

High levels of emotional exhaustion (63.33%) and cynicism (56.67%) were observed, while 55% of students exhibited low resilience. Significant correlations included a negative low correlation between cynicism and resilience in first-year students (r = -0.480; p = 0.018), a negative moderate correlation between emotional exhaustion and resilience in second-year students (r = -0.571; p = 0.026), and a positive moderate correlation between academic efficacy and resilience in second-year students (r = 0.566; p = 0.028). Overall, a positive low correlation was found between academic efficacy and resilience (r = 0.375; p = 0.003).

Resilience mitigates burnout, particularly emotional exhaustion and cynicism. Targeted interventions to enhance resilience may improve academic efficacy and well-being in medical students under blended learning.

Background/Aims: Cardiovascular disease is the leading cause of death worldwide. This study aimed to investigate the recent nationwide trends in major dietary risk factors for dyslipidemia and atherosclerosis. Methods: We estimated age-standardized mean intakes of fresh fruits, fresh vegetables, whole grains, dietary fiber, and sugar-sweetened beverages (SSBs); and mean percentage of energy intake from protein, total fat, saturated fat, and polyunsaturated fat using nationally representative samples from the Korean National Health Examination and Nutrition Survey 2013–2022. To assess overall diet quality, we calculated mean Korean Healthy Eating Index (KHEI) (range 0–100, higher scores indicating greater diet quality). Results: In 2013–2022, there were overall decreasing trends in age-standardized mean KHEI score and intakes of fresh fruits and vegetables, whole grains, and dietary fiber; and overall increasing trends in mean intakes of SSBs, protein, and dietary fat among both male and female. The KHEI score increased in older adults aged ≥ 60 years, whereas it decreased among younger adults. Throughout the study period, younger adults tended to have lower intakes of fresh fruits, fresh vegetables, and whole grains; higher intakes of SSBs, protein, and dietary fat; and lower KHEI score. The mean KHEI score was lower in male (vs. female) and lower (vs. higher) income groups. Conclusions Our data suggest that, from 2013 to 2022, there was a trend toward an unhealthy diet in Korean adults. Our findings also suggest dietary inequalities among age, sex, and income groups, suggesting the need for more intense interventions targeting the vulnerable populations.
