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.

Purpose: Non-operative management (NOM) has emerged as a promising organ-preserving strategy for patients with rectal cancer who achieve a clinical complete response (cCR) after neoadjuvant chemoradiotherapy (CRT). However, no standardized treatment protocol has been established for watch-and-wait strategies. Materials and Methods: This prospective study evaluated oncological outcomes of NOM combined with 4 months of adjuvant capecitabine. Patients with resectable rectal cancer (≤ 8 cm from the anal verge, cT2-4 or N+) underwent CRT (50-54 Gy in 25-27 fractions with capecitabine). Eight weeks post-CRT, a multidisciplinary team assessed cCR. Patients achieving cCR received six cycles of capecitabine (2 weeks on/1 week off) and were actively monitored. Results: Among 89 patients receiving CRT (2018-2023), 17 (19.1%) achieved cCR and were included. The median age was 65 years, and 64.7% were male. Eleven (64.7%) completed all six cycles of adjuvant therapy. After a median follow-up of 31.4 months, 11 patients (64.7%) remained disease-free. Local regrowth occurred in six patients (35.3%) with 2- and 4-year rates of 34.5% and 47.6%, respectively. Five underwent radical surgery, and one received transanal excision with systemic chemotherapy. At the time of assessment, 15 patients (88.2%) showed no evidence of disease, while two (11.8%) received palliative chemotherapy. All patients were alive. Conclusion NOM with adjuvant capecitabine showed promising oncological outcomes, offering an alternative to passive watch-and-wait approaches. Further refinement through multidisciplinary strategies is warranted.

Non-steroidal anti-inflammatory drugs(NSAIDs),commonly utilized analgesics,are extensively employed for managing pain associated with musculoskeletal disorders or injuries.Recent clinical studies have demonstrated a heightened risk of bone stress injuries(BSI)in soldiers and athletes,particularly during high-intensity training,due to NSAID usage.Furthermore,the impact of NSAIDs on fracture healing is well-documented;however,the precise mechanism by which their use during training contributes to an increased incidence of stress bone injuries remains unclear.This article aims to summarize potential mechanisms through an extensive review of domestic and international literature in order to standardize the utilization and clinical management of NSAIDs,optimize pain management strategies,and prevent stress bone injuries or fractures in specific populations such as soldiers and elite athletes.

Objective To investigate the influence of different disinfectants on the ultrasound-guided internal jugular vein puncture and adhesive application.Methods A total of 102 emergency patients with traumatic hemorrhage who underwent ultrasound-guided internal jugular vein puncture and catheterization were selected as the study subjects and randomly divided into the iodine group(51 cases)and the chlorhexidine-alcohol group(51 cases).Iodophor(0.5%effective iodine)and 2.0%chlorhexidine gluconate+70.0%ethanol were used for disinfection before puncture,respectively.The disinfection effect of the puncture site,puncture condition,ultrasound imaging,and adhesive force of the application of patients were statistically compared between the two groups.Results There was no significant difference in the bacterial count before disinfection,the bacterial count after disinfection or the qualified rate of disinfection at the puncture site of patients between the two groups(P>0.05).There were significant differences in the success rate of one-time puncture,the number of puncture and the time of puncture and catheterization between the two groups(P<0.05).There were significant differences in the rate of clear ultrasound images,adhesive force and rate of warping or shedding of the application between the two groups(P<0.05).Conclusion For emergency patients with traumatic hemorrhage,using iodophor(0.5%effective iodine)and 2.0%chlorhexidine gluconate+70.0%ethanol disinfection before ultrasound-guided internal jugular vein puncture can achieve good disinfection effects.Iodine disinfection can obtain clearer ultrasound images and a higher success rate of one-time puncture,but the adhesive force of the application is poor,making it prone to warping or shedding.

Objective To analyze the clinical value of plasma insulin-like factor 6(INSL6)in predicting the risk of acute aortic syndromes(AAS)and adverse outcomes.Methods A retrospective case-control trial was conducted on 194 AAS patients admitted to Department of Cardiovascular Diseases of Second Affiliated Hospital of Army Medical University between April 2021 and June 2023.Another 194 sex-,age-and BMI-matched individuals without aortic diseases were recruited from the health examination center between December 2021 and January 2024.Their plasma INSL6 level was measured with ELISA,and the general clinical data and results of some laboratory tests were collected and compared between the 2 groups.Spearman correlation analysis was used to assess the relationship between plasma INSL6 and other variables,receiver operating characteristic(ROC)curve was plotted to evaluate the diagnostic efficacy of INSL6 for AAS occurrence,multivariate conditional logistic regression model was utilized to analyze the association between plasma INSL6 and AAS onset,and Kaplan-Meier survival curve and multivariate Cox proportional hazards regression model was applied to analyze the relationship between acute-phase plasma INSL6 level and adverse prognosis in AAS patients.Results The plasma INSL6 level was significantly higher in AAS patients at acute phase than the control individuals[704.40(481.32～1 152.62)vs 141.24(107.60～163.72)pg/mL,P<0.001],but no statistical difference was observed in the level among the patients with different AAS subtypes(aortic dissection,intramural hematoma,and penetrating aortic ulcer).Spearman correlation analysis showed that the plasma INSL6 level was positively correlated with platelet count(r=0.325,P<0.001)and hemoglobin concentration(r=0.186,P=0.009),and negatively with IL-6(r=-0.182,P=0.011),INF-γ(r=-0.283,P<0.001),and D-dimer levels(r=-0.195,P=0.006).Multivariate conditional logistic regression analysis revealed that plasma INSL6 level was independently associated with the occurrence of AAS(OR=28.634,95%CI:7.267～112.820,P<0.001).ROC curve analysis further confirmed that the optimal cutoff value of plasma INSL6 in predicting AAS was 259.425 pg/mL,with a sensitivity of 95.9%and a specificity of 98.5%at this threshold.Kaplan-Meier curve analysis demonstrated that AAS patients with low INSL6 level had significantly lower cumulative survival rates(P=0.020)and event-free survival rates(P=0.004)than those with high INSL6 level(P<0.05).Multivariate COX regression analysis revealed that,after adjusting for sex,age,systolic blood pressure,ST classification,and surgical treatment,acute-phase INSL6 level was independently associated with all-cause mortality(HR:0.999,95%CI:0.999～1.000,P=0.023),AAS-related mortality(HR:0.999,95%CI:0.998～1.000,P=0.012),and composite endpoint events(HR:0.999,95%CI:0.999～1.000,P=0.026)in AAS patients during follow-up.Conclusion Plasma INSL6 level is closely associated with the occurrence and adverse prognosis of AAS,and the indicator is expected to be an effective biomarker for diagnosing AAS and predicting its prognosis.

Background and Objectives: Hypertrophic cardiomyopathy (HCM) increases the risk of sudden cardiac death. Despite international guidelines for sudden death prevention and implantable cardiac defibrillator (ICD) use, clinical practices vary. This study assessed the practices and opinions of Korean cardiologists on HCM management, focusing on ICD use and reimbursement policies. Methods: A structured electronic survey was distributed to members of the Korean Society of Cardiology, covering HCM management, ICD preferences, and reimbursement policies. Results: A total of 119 cardiologists participated, with most being arrhythmia specialists (56.3%) and university professors (81.5%). Cardiac magnetic resonance imaging and genetic testing were underutilized (30.3% and 11.8%, respectively). Beta-blocker-refractory premature ventricular complexes were primarily managed with continued medical therapy (77.3%). ICD preferences varied by physician specialty and patient age, with subcutaneous ICDs preferred in younger patients and dual-chamber ICDs in older patients. Nearly half of respondents believed ICD reimbursement criteria required revision. Conclusions Significant variability in HCM management exists among Korean cardiologists, influenced by restrictive reimbursement criteria rather than clinical guidelines. Updated reimbursement policies and improved access to advanced diagnostics are needed to align with international standards and optimize patient care.

Objective: Internet gaming disorder (IGD) is a growing problem, particularly among adolescents. Although cocaine- and amphetamine- regulated transcript (CART) has been explored as a potential biomarker for addictive disorders, its relationship with IGD remains poorly understood. This study investigated the differences in serum CART levels between adolescents with IGD and healthy controls (HCs) in order to find potential biomarkers as a therapeutic target in IGD. Additionally, we investigated correlations of serum CART levels with personality traits within the IGD group. Methods: A total of 114 adolescents participated in this study (43 in the IGD group and 71 in the HC group). Blood samples (10 mL) were collected and serum CART concentrations were determined using an enzyme-linked immunosorbent assay. Participants also completed the Junior Temperament and Character Inventory. Results: Serum CART levels in the IGD group were significantly lower than those in the HC group (p<0.05). IGD participants had higher novelty-seeking and harm-avoidance traits, accompanied by reduced persistence, self-directedness, and cooperativeness. Notably, a significant correlation emerged between serum CART levels and cooperativeness within the IGD group. Lower cooperativeness trait scores could indicate reduced social interaction. Conclusion The present findings suggest serum CART levels might serve as a neurobiological marker for cooperativeness function in adolescents with IGD.
