Objective:
To classify life stages for companion dogs and cats by identifying clusters in age-specific disease proportions derived from medical records, providing a data-driven foundation for health examination programs.
Methods:
We collected 505,667 medical records from 82 veterinary facilities in South Korea between 2020 and 2023. Diagnoses were standardized using GPT-4o and S-BioBERT. Following preprocessing, data from 27 facilities yielded 222,706 canine and 39,910 feline records for the final analysis. Principal component analysis and K-means clustering (K = 4) were applied to age-specific disease proportions to identify life stages.The 10 most highest-proportion diagnoses diseases were determined for each cluster.
Results:
Canine life stages were classified as ≤ 1 year, 2–5 years, 6–10 years, and 11–15+ years.Feline life stages were 1–2 years, 3–8 years, 9–12 years, and 13–15+ years. In dogs, developmental diseases were common in the youngest age group, while chronic diseases were more prevalent in older groups. In cats, oral and urinary diseases were high-ranking, conjunctivitis was most common in the early stage, and chronic diseases increased with age.
Conclusions
and Relevance: Age-specific diagnosis patterns support four practical life stages for dogs and cats in South Korea. These boundaries can inform evidence-based preventive examination schedules, animal health policy, and pet insurance product design.

BACKGROUND:
Data on drug-coated balloon (DCB) treatment in elderly patients are limited. This study was to evaluate the efficacy of DCB treatment in percutaneous coronary intervention (PCI) among elderly patients.
METHODS:
A retrospective analysis included 232 patients aged 75 years or older with coronary artery disease who underwent successful PCI using either DCB alone or in combination with drug-eluting stent (DES) based on pre-dilation results (DCB-based PCI). These patients were compared with 1818 elderly patients who underwent second-generation DES implantation (DES-only PCI). The endpoint was major adverse cardiovascular events (MACE) at 2-year follow-up.
RESULTS:
In the DCB-based PCI, 61.2% of patients received DCB-only treatment. Compared to DES-only PCI, the DCB-based PCI group had fewer stents (0.5 ± 0.7 and 1.7 ± 0.8, P < 0.001), shorter stent lengths (13.3 ± 20.9 mm and 37.4 ± 23.0 mm, P < 0.001), and lower usage of small stents with a diameter of 2.5 mm or less (15.6% and 28.7%, P = 0.010). The DCB-based PCI group exhibited lower rate of MACE (5.5% and 13.1%, P = 0.003), target vessel revascularization (1.1% and 5.6%, P = 0.017) and major bleeding (0.7% and 5.1%, P = 0.009) at 2-year follow-up. The reduced risk in 2-year MACE was consistently observed across various matching procedures, with the most significant reduction noted in target vessel revascularization and major bleeding.
CONCLUSION
The DCB-based PCI reduced stent burden, particularly in the usage of small diameter stents, and was associated with lower risks of MACE, target vessel revascularization, and major bleeding compared to DES-only PCI in elderly patients.

Purpose:
Intertrochanteric hip fractures are commonly seen in the elderly population. Osteosynthesis is technically demanding and has a high rate of failure, especially in osteoporotic bones. Furthermore, delayed ambulation after surgery can be a risk factor for systemic complications. Active prevention of prolonged bed-ridden can improve the quality of life postoperatively. For early ambulation, the authors chose hemiarthroplasty as the surgical method. The purpose of this study was to assess the efficacy of cemented bipolar hemiarthroplasty with a wiring technique for unstable intertrochanteric hip fractures in the elderly.
Materials and Methods:
A retrospective review was conducted on the records of 41 patients with unstable intertrochanteric hip fractures treated with cemented bipolar hemiarthroplasty between January 2019 and December 2022. The mean patient age was 82 years, and cemented bipolar hemiarthroplasty with a wiring technique was performed in all cases. Clinical and radiologic outcomes were analyzed. The rate of complications and modified Harris hip score (HHS) at one-year follow-up were reviewed.
Results:
Early ambulation was initiated at a mean of 7.8 days postoperatively. Eight patients had systemic complications but recovered prior to discharge. There were no complications of loosening, dislocation, or infection indicated at the minimum one-year postsurgical follow-up. The mean modified HHS was 75.8.
Conclusion
Cemented bipolar hemiarthroplasty with a wiring technique showed positive clinical results in the treatment of unstable intertrochanteric hip fractures in elderly patients with osteoporosis. Furthermore, early ambulation could prevent recumbency-related complications. As a result, this technique is considered a good surgical alternative for an aging population.

Purpose:
This study aimed to explore customer perspectives of nursing services in tertiary hospitals.
Methods:
The data comprised mobile Voice Of Customer (VOC) data related to “nursing” or “nurses” generated from June 25, 2019, to December 31, 2022, in a tertiary hospital. A total of 44,727 VOC data points were collected, of which 4,040 were selected for the final analysis. Text network analysis and topic modeling were conducted using NetMiner 4.5.1.
Results:
Topic modeling identified five topics for positive aspects and four topics for areas requiring improvement.The positive aspects were: 1) sincere nursing care; 2) rapid response from professional medical staff; 3) teamwork for delivering customer-centric services; 4) provision and coordination of system-based healthcare services; and 5) customer-focused responsiveness. The areas requiring improvement were: 1) demand for skilled nursing care tailored to customer expectations; 2) demand for enhanced communication and reduced mechanical responses; 3) demand for appropriate handling of diverse situations; and 4) demand for overall improvements to the healthcare system, including reservation systems.
Conclusion
These results may be used to enhance customer and patient experiences in tertiary hospitals and are necessary for utilization from a hospital management perspective.

Background:
There is increasing evidence that probiotics are effective in treating allergic rhinitis (AR), while some controversies remain. This study was performed to evaluate the therapeutic effect and safety of a mixture of Bifidobacterium longum and Lactobacillus plantarum (NVP-1703) in children with AR.
Methods:
In a randomized, double-blind, placebo-controlled study, children aged 6 to 19 years with perennial AR were treated with NVP-1703 at a dose of 1 × 1010 CFU/day or placebo once a day for 4 weeks. Total nasal symptom score (TNSS), nasal symptom duration score (NSDS), quality of life (QoL), allergic inflammatory markers, and safety parameters were evaluated.
Results:
After 4 weeks of treatment, the TNSS in the NVP-1703 group significantly decreased compared to that in the placebo group (P = 0.011), both in the morning and the evening (P = 0.031 and P = 0.004, respectively). The NSDS also significantly decreased in the NVP-1703 group compared to that in the placebo group (P = 0.018). QoL scores, particularly those related to mouth breathing and itchy nose, showed a significant improvement in the NVP-1703 group compared to the placebo group. The ratios of interleukin (IL)-4/IL-22 and IL-5/IL-22 were significantly reduced in the NVP-1703 group after the treatment compared to the baseline values. No notable adverse events were reported in the NVP-1703 group.
Conclusion
Oral administration of a mixture of B. longum and L. plantarum (NVP-1703) improved both AR symptoms and QoL in children with perennial AR, accompanied by decreases in the ratios of T helper 2 cytokines to IL-22.

Cerebrospinal fluid (CSF) leakage is a rare complication that can occur due to dural defects during spinal surgery, hindering the improvement of the surgical site and increasing the possibility of infection. DuraSeal® is a dural sealing adhesive that prevents CSF leakage and is used as an adjunct to enable the watertight repair of dural defects when the dura is damaged during spinal surgery. In the present case, DuraSeal® was applied to repair a dural defect in the surgical area after thoracic spine surgery, and no neurological problems occurred immediately after surgery. However, a day later, the patient’s paraparesis worsened; therefore, reoperation was performed and the symptoms improved.
