Objective: To explain process of developing basic veterinary clinical performance guidelines, based on frequently observable clinical manifestations, thereby supporting competencybased veterinary education in Korea. Methods: A structured review of learning outcomes established by Korean Association of Veterinary Medical Colleges (KAVMC) was conducted by a planning committee including veterinary educators, practitioners, and advisory members. Owner-oriented descriptions were used to frame each performance task, and each was mapped to corresponding learning outcomes. These tasks were aligned with learning outcomes recommended by the KAVMC to support the development of communication, clinical reasoning, and performance-related competencies among veterinary students, thereby enhancing day-one clinical readiness. Results: In total, 63 clinical manifestations for a guidebook format that can be used for clinical education were identified and categorized by organ systems that are described in language understandable to animal owners. Conclusions and Relevance: The basic veterinary clinical performance guidelines based on common clinical manifestations would serve as a vital component in veterinary education to reinforce core graduation competencies.

Heart failure (HF) is a major cause of mortality and morbidity in South Korea, imposing substantial physical, emotional, and financial burdens on patients and society. Despite the high burden of symptom and complex care needs of HF patients, palliative care and hospice services remain underutilized in South Korea due to cultural, institutional, and knowledge-related barriers. This position statement from the Korean Society of Heart Failure emphasizes the need for integrating palliative and hospice care into HF management to improve quality of life and support holistic care for patients and their families. By clarifying the role of palliative care in HF and proposing practical referral criteria, this position statement aims to bridge the gap between HF and palliative care services in South Korea, ultimately improving patient-centered outcomes and aligning treatment with the goals and values of HF patients.

Background: Postoperative fever is common. However, it can sometimes indicate severe complications such as sepsis or pneumonia. Intensive care unit (ICU) patients who have undergone abdominal surgery have a higher risk of postoperative fever due the physical severity of this type of surgery. Nevertheless, determining when more aggressive or invasive management of fever is necessary remains a challenge. Methods: We analyzed the Medical Information Mart for Intensive Care (MIMIC)-IV and MIMIC-IV-Note databases, which are open critical care big databases from a single institute in the United States. From this, we selected ICU patients who developed fever after intra-abdominal surgery and classified these patients into two groups using cluster analysis based on diverse variables from the MIMIC-IV databases. Following this cluster analysis, we assessed differences among the identified groups. Results: Of 2,858 ICU stays after intra-abdominal surgery, 331 postoperative fever cases were identified. These patients were clustered into two groups. Group A included older patients with a higher mortality rate, while group B consisted of younger patients with a lower mortality rate. Conclusions Postoperative ICU patients with a fever could be classified into two distinct groups, a high-risk group and low-risk group. The high-risk patient group was characterized by older age, higher Sequential Organ Failure Assessment (SOFA) score, and more unstable hemodynamic status, indicating the need for aggressive management. Clustering postoperative fever patients by clinical variables can support medical decision-making and targeted treatment to improve patient outcomes.

Purpose: We evaluated the short-term efficacy and safety of hyaluronic acid (HA) eye drops over a 1-month observational period in patients treated with different HA concentrations for dry eye disease. Methods: This prospective, non-interventional, multicenter observational study included patients aged ≥ 19 years who were diagnosed with dry eye at participating medical institutions and treated with HA eye drops (Xenobella SD; ChongKunDang Pharm., Seoul, Korea). In total, 886 eyes from 886 patients were analyzed. Efficacy was evaluated by changes in tear film break-up time (TBUT), ocular surface staining score, dry eye severity, ocular discomfort scale, and the Ocular Surface Disease Index (OSDI) from baseline to 1 month after treatment. Subgroup analyses were conducted to assess efficacy according to age, contact lens use, and HA concentration. Safety was evaluated using a questionnaire on adverse events. Results: After 1 month of treatment, all dry eye parameters―ocular surface staining score, TBUT, ocular discomfort scale, OSDI, and dry eye severity―improved significantly. Subgroup analyses revealed greater improvement in selected parameters, including TBUT, among patients <60 years, contact lens users, and those treated with higher concentrations of HA (0.18% or 0.3%), compared to patients aged ≥60 years, non–contact lens users, and those receiving the lower concentration of HA (0.1%). Only five mild adverse events were reported. Conclusions This 1-month observational study demonstrated that HA eye drops significantly improved both signs and symptoms of dry eye with minimal adverse events. Therapeutic benefits were more pronounced in younger patients, contact lens users, and those treated with higher HA concentrations (≥0.18%).

Background: Three-dimensional (3D) skin displacement vector analysis method provides a deeper understanding of dynamic muscle anatomy. Understanding the dynamic muscle anatomy in the glabellar area during frowning can facilitate safer and effective botulinum toxin injections for treating glabellar wrinkles. Objective: We aimed to investigate the skin displacement patterns of the glabellar area and adjacent skin during contraction of the glabellar muscles using 3D skin vector displacement analysis. Methods: Twenty-nine healthy individuals (26 female, 3 male; median age 40.5 years) participated in the study. Photographs of the face were taken at rest and during maximal contraction of the glabellar muscles. Each expression image was aligned to its respective static image to compute the differences in the skin position. Results: Two skin displacement patterns were identified during frowning: lateral pattern (89.66%), in which main skin vector displacement located on the eyebrow area and central pattern (10.34%), in which skin vector displacement mostly located between eyebrows. 62.07% showed asymmetric skin displacement. Analysis of the glabellar patterns showed that the 'U', '11', 'X', and 'π' patterns were observed in 38%, 38%, 14%, and 10% of cases, respectively, with corresponding skin vector displacement angles of 48°, 32°, 74°, and 24°. Additionally, 20.69% of subjects exhibited upward skin movement in the medial frontalis area during frowning. In 48% of subjects, the lateral and inferior portions of the orbicularis oculi muscle contracted, along with the upper medial portion. Conclusion This data will serve as an important guide for Botulinum Toxin treatment of glabella wrinkles in Korean patients.

Cardiovascular disease is an important risk factor for mortality among kidney transplant recipients. In this study, we aimed to investigate the association between cardiovascular risk score at kidney transplantation and long-term outcomes of patients. Methods: In this prospective, observational cohort study, we enrolled kidney transplant recipients who participated in the Korean Organ Transplantation Registry and underwent transplantation between April 2014 and December 2019. The cardiovascular risk status of kidney transplant recipients was assessed using the Framingham risk score. All-cause mortality, major adverse cardiovascular events, allograft failure, estimated glomerular filtration rates (eGFRs), and composite outcomes were evaluated after kidney transplantation. Results: Of the 4,682 kidney transplant recipients, 96 died during 30.7 ± 19.1 months of follow-up. The Kaplan-Meier survival analysis results showed that high Framingham risk scores were associated with all-cause mortality, major adverse cardiovascular events, and composite outcomes. According to the multivariable Cox analysis, high Framingham risk scores were associated with an increased risk of mortality (hazard ratio [HR], 3.20; 95% confidence interval [CI], 1.30–7.91), major adverse cardiovascular events (HR, 8.43; 95% CI, 2.41–29.52), and composite outcomes (HR, 2.05; 95% CI, 1.19–3.46). The eGFRs after transplantation were significantly higher among patients in the low Framingham risk score group (p < 0.001). However, Framingham risk scores were not associated with graft loss or rapid decline in eGFRs. Conclusion: The Framingham risk score is a useful indicator of cardiovascular events, mortality, and kidney function after kidney transplantation.

As the prevalence of myopia has recently increased, there is growing interest in interventions to slow myopia progression. The choroid, the rearmost and largest part of the uveal layer, is a tissue rich in blood vessels located between the retina and the sclera. Recent advancements in diagnostic equipment have enabled direct imaging of the choroid, leading to increased research on its role in both normal and pathological conditions. Regarding myopia, it has been reported that; 1) the choroidal thickness decreases as the degree of myopia and axial length increase, 2) in the case of moderate to high concentrations of atropine or orthokeratology lenses, which are known to slow myopic progression, choroidal thickening is accompanied from the early stages of application, and 3) the mechanism by which choroidal thickening slows myopia progression is also being actively investigated. As a result, the choroid is being recognized as a therapeutic target for developing new interventions to slow myopia progression. Additionally, the increase in choroidal thickness has been reported as a predictive factor for the subsequent myopia progression, suggesting its potential role as a biomarker for assessing the likelihood of future myopia progression.

The Asian Society of Cardiovascular Imaging-Practical Tutorial (ASCI-PT) is an instructional initiative of the ASCI School designed to enhance educational standards. In 2021, the ASCI-PT was convened with the goal of formulating a consensus statement on the assessment of coronary stenosis and coronary plaque using coronary CT angiography (CCTA). Nineteen experts from four countries conducted thorough reviews of current guidelines and deliberated on eight key issues to refine the process and improve the clarity of reporting CCTA findings. The experts engaged in both online and on-site sessions to establish a unified agreement. This document presents a summary of the ASCI-PT 2021 deliberations and offers a comprehensive consensus statement on the evaluation of coronary stenosis and coronary plaque in CCTA.

Purpose: To investigate the effect of the postoperative spherical equivalent (SE) and astigmatism on the uncorrected near/distance visual acuity (UNVA/UDVA) in monofocal intraocular lens (IOL)-implanted pseudophakic eyes. Methods: Of the eyes that underwent successful cataract surgery and monofocal IOL implantation from January 2020 to September 2021 by a single surgeon, eyes with postoperative astigmatism ≤ 1.5 diopters (D) and -0.75 D ≤ SE < +0.25 D were included. Eyes implanted with a toric IOL or with a best corrected visual acuity under 20/25 were excluded. This was a cross-sectional study, and the correlation of SE/astigmatism and UNVA/UDVA at 1 month postoperatively was analyzed retrospectively. The eyes were divided into mini-myopia (-0.75 D ≤ SE < -0.25 D) and emmetropia (-0.25 D ≤ SE < 0.25 D) groups according to the SE. Results: This study included 118 eyes (86 patients). The UNVA was significantly better in the mini-myopia group than in the emmetropia group (p = 0.009), without a significant difference in UDVA (p = 0.412). Dividing the range into 0.5 D units according to the degree of astigmatism, no significant difference was observed in UNVA/UDVA between the mini-myopia and emmetropia groups in eyes with astigmatism ≤ 1.0 D. However, the mini-myopia group had a significantly better UNVA (p = 0.03), without a significant difference in UDVA (p = 0.879) in eyes with astigmatism > 1.0 D or ≤ 1.5 D. Conclusions In non-toric monofocal IOL-implanted pseudophakic eyes with postoperative residual astigmatism of ≤ 1.5 D, especially in eyes with astigmatism > 1.0 D and ≤ 1.5 D, the mini-myopia group had a significantly better UNVA compared to the emmetropia group, without a significant difference in UDVA.
