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.

Background: With the aging population and advancements in medical care worldwide, the number of older patients with end-stage kidney disease continues to rise. This study aimed to identify factors associated with osteoporosis and osteopenia in older patients undergoing incident hemodialysis and assess their impact on mortality. Methods: We analyzed a large multicenter retrospective cohort of patients aged ≥70 years undergoing incident hemodialysis to identify factors associated with osteoporosis using logistic regression analysis and to assess the association of death with osteoporosis and osteopenia using Cox multivariable analysis. Results: Among 710 patients, 39.0% and 19.6% had osteoporosis and osteopenia, respectively. Osteoporosis was significantly associated with female sex, a history of fractures, and the absence of phosphate binder use. During a median follow-up of 36.8 months, 348 participants (58.8%) died. Mortality rates were the highest in the osteoporosis group (79.8%), followed by the osteopenia (77.2%) and normal bone mineral density (BMD) groups (35.2%). Cox regression analysis revealed that even after adjusting for covariates, the osteoporosis group was significantly associated with a higher mortality risk than the normal BMD group. Osteoporosis at the start of hemodialysis was significantly associated with higher mortality. Conclusion We should consider the importance of bone health in patients undergoing incident hemodialysis and pay attention to the use of phosphate binders and fracture prevention.

Background: Obesity is a well-known risk factor for chronic kidney disease and its progression. However, the impact of obesity on the renal function of the elderly population is uncertain. We investigated the association between obesity and renal outcomes in the elderly. Methods: We analyzed 130,504 participants from the Korean National Health Insurance Service-Senior cohort. Obesity was classified according to body mass index (BMI), sex-specific waist circumference (WC), and the presence of metabolic syndrome. The primary outcome was renal function decline, defined as a decline in the estimated glomerular filtration rate (eGFR) of at least 50% from baseline or new-onset end-stage renal disease. Results: During a follow-up period of 559,531.1 person-years (median, 4.3 years), 2,486 participants (19.0%; incidence rate of 4.44 per 1,000 person-years) showed renal function decline. A multivariate Cox proportional hazards model revealed that BMI/WC was not associated with renal function decline. However, the group with metabolic syndrome had a significantly increased risk of renal function decline compared to the group without metabolic syndrome (adjusted hazard ratio [HR], 1.24; 95% confidence interval [CI], 1.13–1.36). Compared with the non-metabolic syndrome group, the adjusted HRs (95% CI) for participants with one through five components were 0.96 (0.84–1.11), 1.10 (0.96–1.27), 1.24 (1.06–1.45), 1.37 (1.12–1.66), and 1.99 (1.42–2.79), respectively (p for trend < 0.001). Conclusion In elderly Korean adults, metabolic syndrome and the number of its components were associated with a higher risk of renal function decline, but BMI or WC was not significant.

Background: Arthroscopic repair of bucket-handle meniscal tears (BHMTs) is technically challenging owing to the complexity of the tear patterns. Compared to simpler meniscal tears, BHMTs are associated with a higher failure rate and often require subsequent meniscectomy. This study aimed to assess clinical outcomes, failure rates, and risk factors for failure following primary arthroscopic repair of BHMTs. Methods: Seventy-four patients (mean age, 27.2 ± 11.2 years) who underwent arthroscopic BHMT repair were included (mean follow-up period, 60.2 ± 36.0 months). Analyzed risk factors included age, sex, body mass index, chronicity, laterality, tear zone, and concomitant anterior cruciate ligament reconstruction. Clinical failure was defined as the presence of clinical symptoms consistent with a meniscus tear and the need for subsequent surgery. The Kaplan-Meier method and log-rank test were performed to compare groups classified by postoperative meniscal healing status on magnetic resonance imaging (MRI) at a mean follow-up period of 7.30 ± 1.80 months. Clinical outcomes were assessed using the Tegner activity score, Lysholm knee score, and Hospital for Special Surgery (HSS) knee score. Results: The clinical failure rate was 14.9% (11 / 74). Six patients underwent subtotal meniscectomy, and 5 patients underwent partial meniscectomy. Red-white zone involvement was a significant risk factor for clinical failure (odds ratio, 6.182; 95% CI, 1.093–34.950; p = 0.039). Survival analysis based on postoperative MRI findings revealed a significant difference among 3 groups (p = 0.008): the completely healed group showed a 100% survival rate (20 / 20); the partially healed group, 80% (32 / 40); and the unhealed group, 0% (0 / 5). Patients with lateral BHMTs had a significantly higher rate of complete healing than those with medial BHMTs (46.4% vs. 18.9%; p = 0.014). At the final follow-up, the non-failure group demonstrated significantly higher Tegner activity (5.1 ± 1.2 vs. 4.4 ± 0.5; p = 0.038), Lysholm knee (87.7 ± 6.2 vs. 83.2 ± 3.1; p = 0.029), and HSS knee (93.9 ± 4.7 vs. 89.6 ± 3.0; p = 0.007) scores than the failure group. Conclusions BHMTs involving the red-white zone or located in the medial meniscus—particularly those showing inferior early postoperative MRI healing—should be closely monitored after surgery.

Background: Excess intake of added sugars contributes to obesity, type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), and premature mortality. Sugar-sweetened beverages (SSBs), the main source of added sugars, are consistently linked to adverse outcomes. Artificially sweetened beverages (ASBs) have been suggested as short-term substitutes, but evidence regarding benefits and harms remains inconclusive, and guidance is lacking. Methods: This consensus statement draws on a structured evidence review combining two approaches: an updated meta-analysis of randomized controlled trials (RCTs) assessing short- to intermediate-term effects of replacing SSBs with ASBs on weight and metabolic outcomes; and an umbrella review of systematic reviews of cohort studies evaluating long-term associations of SSBs and ASBs with major outcomes, including mortality, CVD, and T2DM. Results: In 14 RCTs (3–76 weeks), replacing SSBs with ASBs produced modest reductions in body weight (–0.73 kg) and body fat (–0.72%), with inconsistent effects on glycemic and cardiometabolic markers. Evidence from 20 systematic reviews of cohorts (up to 34 years follow-up) showed that higher intake of both SSBs and ASBs was associated with increased risks of T2DM, CVD, and mortality, with relative risks for ASBs similar to those for SSBs. Conclusion ASBs may serve as a short-term substitution for individuals with high SSB intake, particularly those at elevated metabolic risk. However, regular or long-term use is not recommended due to uncertain safety and potential reinforcement of sweet preference. Public health strategies should emphasize reducing both SSBs and ASBs, prioritizing water and unsweetened beverages as the ultimate goal.

Janus kinase (JAK) inhibitors are an important treatment option for ulcerative colitis, providing rapid onset of action, oral administration, and efficacy even after biologic failure. The 3 approved agents—tofacitinib, filgotinib, and upadacitinib—differ in JAK isoform selectivity, leading to clinically meaningful differences in efficacy and safety. Evidence from network meta-analyses, clinical trials, and real-world studies consistently shows that upadacitinib provides the highest efficacy for induction and maintenance of remission, whereas filgotinib demonstrates the most favorable safety profile. The strong efficacy of upadacitinib and tofacitinib is particularly relevant in patients with severe disease, including acute severe ulcerative colitis, and upadacitinib maintains high efficacy regardless of prior advanced therapy exposure. JAK inhibitors also benefit extraintestinal manifestations. Although risks such as herpes zoster, serious infection, thromboembolism, and major cardiovascular events differ among agents, long-term data suggest generally acceptable safety when used appropriately. Intraclass JAK-to-JAK cycling is feasible, with about half of patients achieving steroid-free clinical remission in retrospective cohorts. Based on mechanistic, clinical, and real-world evidence, filgotinib may be a first-line option for patients with lower disease activity or when safety is a priority, whereas upadacitinib or tofacitinib may be preferred in higher disease activity. Strategically selecting agents may improve durability and outcomes.

Objective: Patients with panic disorder (PD) are approximately four times more likely than the general population to exhibit suicidal ideation (SI) and suicide attempts. Although prolonged duration of untreated illness (DUI) is a known risk factor for adverse outcomes in mood disorders, its impact on suicidality among patients with PD has not been well established. This study investigated whether prolonged DUI is associated with heightened SI among patients with PD, considering sociodemographic and clinical factors. Methods: A total of 804 patients with PD were recruited. DUI was defined as the time between symptom onset and the initiation of psychiatric treatment. Clinical assessments included the Scale for Suicide Ideation (SSI), Beck Depression Inventory-II (BDI-II), and Panic Disorder Severity Scale. Sociodemographic and clinical predictors of SI were examined using independent t-tests, Pearson’s correlations, and multiple regression analysis. Results: In patients with PD, the mean DUI was 41.56 months. Longer DUI was positively correlated with higher SSI total scores, along with greater depression severity. Gender women, unmarried status, and elevated BDI-II scores were significantly predicted higher SSI total scores. In the multiple regression model, prolonged DUI remained an independent predictor of SSI (B=0.116, p=0.012) after adjusting for other variables. Conclusion These findings indicate that delayed treatment contributes to increased suicidality in PD, beyond demographic and depressive risk factors. Therefore, early detection and timely intervention using treatment strategies that enhance awareness, improve the accessibility of psychiatric services, and provide social support may reduce DUI and mitigate suicide risk among patients with PD.

Purpose: To evaluate the efficacy and safety of latanoprostene bunod 0.024% (LBN) in Korean patients with glaucoma or ocular hypertension in a real-world clinical setting. Methods: This retrospective study included patients who initiated LBN treatment between March 1, 2022, and December 31, 2024. Patients were categorized into monotherapy, switched therapy, and concomitant therapy groups. Changes in intraocular pressure (IOP) were assessed at baseline, month 1, and month 6 according to treatment group and diagnosis. The type and frequency of adverse events were also analyzed. Results: Among the 138 patients initially identified, 129 were included in the analysis. The mean IOP for all patients was 17.4 ± 4.9 mmHg at baseline, 16.0 ± 4.6 mmHg at month 1, and 14.6 ± 3.7 mmHg at month 6. The mean IOP reduction was -1.4 ± 2.8 mmHg at month 1 (p < 0.001) and -2.2 ± 3.3 mmHg at month 6 (p < 0.001). Subgroup analyses by treatment type (monotherapy, switched, and concomitant) and diagnosis revealed significant IOP reductions at both time points across all groups. Adverse events occurred in 22 patients (17.1%), with eye pain being the most frequent. No serious adverse events were observed, including systemic side effects, severe visual impairment, or significant ocular complications. Conclusions LBN significantly reduced IOP in Korean patients with glaucoma and ocular hypertension, irrespective of prior IOP-lowering medication use and was well tolerated with a favorable safety profile. These findings support the use of LBN as an effective treatment option for Korean patients with glaucoma or ocular hypertension in diverse clinical settings.

Background: Rosacea is a chronic inflammatory skin disorder characterized by erythema, papules, ocular symptoms, and heightened sensitivity. Patients with neurogenic symptoms such as burning or stinging remain particularly difficult to manage. Current guidelines often underrepresent energy-based devices (EBDs), pigmentary sequelae, psychosocial burden, and ocular comorbidities. Objective: To examine Korean dermatologists’ expert perspectives on rosacea management, focusing on skin sensitivity, neurogenic symptoms, pigmentary changes, psychosocial impact, ocular involvement, and EBD use. Methods: A web-based, 29-item survey was administered to 25 board-certified Korean dermatologists (May–June 2025). Quantitative and qualitative responses were analyzed. Results: Erythematotelangiectatic and papulopustular phenotypes with sensitivity skin predominated. EBDs (pulsed dye laser, intense pulsed light) were frequently used but limited by cost and sensitivity issues. Neurogenic symptoms were recognized but rarely treated with neuromodulators. Post-inflammatory hyperpigmentation was infrequent, yet monitoring was inconsistent.Psychosocial and ocular aspects were acknowledged but seldomly systematically addressed.Respondents expressed interest in emerging adjunctive treatments such as cold plasma, skin boosters, and holistic care approaches. Conclusion Korean dermatologists adopt individualized strategies for rosacea, yet practice gaps remain regarding neurogenic symptoms, pigmentary complications, and psychosocial and ocular comorbidities. Findings support the need for updated multidisciplinary, phenotype-driven guidelines aligned with real-world practice.

Osteoid osteoma accounts for approximately 10% of all benign bone tumors, but only approximately 4% of cases occur in the foot and ankle area. Periarticular osteoid osteoma frequently manifests with nonspecific clinical symptoms that mimic other conditions, potentially leading clinicians down a diagnostic side path and resulting in delayed or missed diagnoses compared to extra-articular osteoid osteoma. Although plain radiographs may show nonspecific findings, magnetic resonance imaging can detect bone marrow edema and surrounding soft tissue changes. Computed tomography is the most accurate modality for diagnosis. This paper reports the case of a 26-year-old female diagnosed with periarticular osteoid osteoma of the calcaneus and was treated with arthroscopic localized curettage at the author’s institution.
