A raccoon dog (Nyctereutes procyonoides koreensis) was rescued with moderate Sarcoptes scabiei infestation and a pressure sore on the right metatarsal region. The animal exhibited non-weight-bearing lameness in the right hind limb. Radiographic examination revealed osteolytic changes in the right calcaneus. Musculoskeletal ultrasonography of the tarsal region revealed a markedly thickened and inhomogeneous gastrocnemius tendon (GTE), tendon sheath effusion, hyperechoic debris with acoustic shadowing, and an absence of tendon movement during dynamic evaluation—findings consistent with a chronic, severe tendon injury. Magnetic resonance imaging (MRI) confirmed a complete rupture of the right Achilles tendon complex, including the GTE and associated components at the calcaneal midportion. Given the chronic and irreversible nature of the lesion, a right pelvic limb amputation was performed. Postoperative recovery was uneventful. The raccoon dog adapted well to tripod locomotion during rehabilitation and was successfully released into the wild. This case underscores the importance of combining ultrasonography and MRI for accurate diagnosis and clinical decision-making in wildlife medicine and demonstrates that selected individuals with severe musculoskeletal injuries may be viable candidates for release following amputation and rehabilitation.

Canine adenovirus type 2 (CAV-2) is a common causative agent of respiratory disease in canines. There have been no reports of CAV-2 variants isolated from raccoon dogs. This study aims to investigate the biological and genetic characteristics of a novel Korean CAV-2 variant. Madin-Darby canine kidney cells were used to isolate the CAV-2 variant from 45 fecal swab samples. Diagnostic tools such as the cytopathic effect (CPE) assay, electron microscopy, polymerase chain reaction, and immunofluorescence and hemagglutination assays were used to confirm the presence of the CAV-2 isolate. A cross-virus neutralization assay was performed to verify the novelty of this CAV variant. Genetic analysis was performed using nucleotide sequences obtained through next-generation sequencing. The isolate was confirmed to be a CAV-2 variant based on the aforementioned methods and designated CAV2232. The number of bases in the fiber and E3 genes of CAV2232 were 1,626 and 414, respectively. Phylogenetic analysis of the fiber and E3 genes confirmed that CAV2232 was classified into a different clade from the known CAV-1 and CAV-2 strains. Mice inoculated with the CAV2232 vaccine developed high virus neutralization antibody titers of 1,024 (210) against CAV2232, while mice inoculated with CAV-1 and CAV-2 vaccines had low virus neutralization antibody titers of 12.9 (23.7) and 6.5 (22.7), respectively, against CAV2232. CAV2232 isolated from wild raccoon dog feces was classified as a novel CAV-2 variant. CAV2232 may therefore be used as an antigen for new vaccine development and serological investigations.

This case report documents the rescue, clinical presentation, treatment, and recovery of pneumothorax in a female Korean water deer (Hydropotes inermis argyropus) following a vehicular collision. Severe injuries, including a confirmed rib fracture, prompted an extensive treatment plan. Computed tomography imaging confirmed pneumothorax, particularly in the left lung, necessitating thoracocentesis to alleviate the accumulated air. Post-procedural monitoring demonstrated gradual recovery, with the water deer exhibiting restored appetite after the 2nd day of thoracocentesis. Successful recovery marked by natural pneumothorax resolution allowed for treatment cessation on the 13th day after injury.

Economic evaluations in the healthcare are used to assess economic efficiency of pharmaceuticals and medical interventions such as diagnoses and medical procedures. This study introduces the main concepts of economic evaluation across its key steps: planning, outcome and cost calculation, modeling, cost-effectiveness results, uncertainty analysis, and decision-making. When planning an economic evaluation, we determine the study population, intervention, comparators, perspectives, time horizon, discount rates, and type of economic evaluation. In healthcare economic evaluations, outcomes include changes in mortality, the survival rate, life years, and quality-adjusted life years, while costs include medical, non-medical, and productivity costs. Model-based economic evaluations, including decision tree and Markov models, are mainly used to calculate the total costs and total effects. In cost-effectiveness or costutility analyses, cost-effectiveness is evaluated using the incremental cost-effectiveness ratio, which is the additional cost per one additional unit of effectiveness gained by an intervention compared with a comparator. All outcomes have uncertainties owing to limited evidence, diverse methodologies, and unexplained variation. Thus, researchers should review these uncertainties and confirm their robustness. We hope to contribute to the establishment and dissemination of economic evaluation methodologies that reflect Korean clinical and research environment and ultimately improve the rationality of healthcare policies.

Asian Nursing Research 2021;15(3):174-180
Purpose:
This study aimed to identify the risk factors of carbapenem-resistant Enterobacteriaceae (CRE) acquisition to build a nomogram for CRE acquisition risk prediction and evaluate its performance.
Methods:
This unmatched case-control study included 352 adult patients (55 patients and 297 controls) admitted to the intensive care unit (ICU) of a 453-bed secondary referral hospital between January 1, 2018, and September 31, 2019, in Busan, South Korea. The nomogram was built with the identified risk factors using multiple logistic regression analysis. Its performance was analyzed using calibration-in-the-large, the slope of the calibration plot, concordance statistic (c-statistic), and the sensitivity and specificity of the training set, subsets, and a new test set.
Results:
The risk factors of CRE acquisition among ICU patients at a secondary referral hospital were Acute Physiology and Chronic Health Evaluation II score at the time of admission, use of a central venous catheter and a nasogastric tube, as well as use of cephalosporin antibiotics. At 20.0% of the predicted CRE acquisition risk in the training set, the calibration-in-the-large was 0, slope of the calibration plot was 1, c-statistic was .93, sensitivity was 85.5%, and specificity was 84.8%. The performance was relatively good in the subsets and new test set.
Conclusion
The nomogram can be used to monitor the CRE acquisition risk for ICU patients who have a similar case mix to patients in the study hospitals. Future studies need to involve more rigorous methodology and larger samples.
