This study examined the mediating effect of empowerment on the relationship between nursing professionalism and job satisfaction, with the goal of informing strategies to enhance job satisfaction among insurance review nurses. Methods: A total of 165 insurance review nurses with more than 1 year of work experience in 12 general hospitals (≥500 beds) participated in this study. Data were analyzed using descriptive statistics, t-tests, analysis of variance, Pearson correlation analysis, and multiple regression analysis. The mediating effect was tested using the PROCESS Macro (model 4) in SPSS version 26.0 with 10,000bootstrap samples. Results: The mean scores for nursing professionalism, empowerment, and job satisfaction were 100.37 (standard deviation [SD], 17.03), 86.24 (SD, 17.70), and 45.44 (SD, 9.17), respectively. Significant positive correlations were observed between nursing professionalism and job satisfaction (r=.64, p<.001), empowerment and job satisfaction (r=.77, p<.001), and nursing professionalism and empowerment. Empowerment was found to partially mediate the relationship between nursing professionalism and job satisfaction (95% CI, .20–.44). Conclusion: Enhancing empowerment and strengthening nursing professionalism are essential for improving job satisfaction among insurance review nurses. Institutional interventions that promote professional identity and provide structural empowerment may increase job satisfaction and support retention within this specialized nursing workforce.

Objective:
This study aimed to validate the reliability and validity of the Diagnostic Interview for the Internet Addiction Scale (DIA) among Korean children and adolescents in the clinical setting.
Methods:
We collected the clinical data from university hospitals in South Korea and 194 children and adolescents (aged 7–18 years) completed the questionnaire. The content validity was conducted on 10 items of the DIA and an internal consistency test was performed for the verification of reliability.
Results:
Participants on average, aged 13.17 years (standard deviation=2.46), and 75.3% (n=146) were boys. The DIA was highly correlated with the scores of the Korean scale for Internet addiction for adolescents, Young’s Internet Addiction Test, Internet addiction proneness scale for children and adolescents. The overall sampling suitability of the 10-item scale was tested using the Kaiser–Meyer–Olkin, resulting in a high value of 0.861. The DIA revealed a two-factor structure and the Cronbach’s alpha correlation coefficient for the total scale was 0.806. Confirmatory factor analysis showed an acceptable model fit (root-mean square error of approximation=0.058, comparative fit index=0.950, and Tucker-Lewis Index=0.919).
Conclusion
The DIA may suggest in-depth-scale examinations of the factors that influence Internet addiction. We may expect that DIA would be used efficiently for the diagnosing of Internet addiction and further studies for the assessment.

Background:
Primary cutaneous CD30+ lymphoproliferative disorders (pcCD30-LPDs) are a diseases with various clinical and prognostic characteristics.
Objective:
Increasing our knowledge of the clinical characteristics of pcCD30-LPDs and identifying potential prognostic variables in an Asian population.
Methods:
Clinicopathological features and survival data of pcCD30-LPD cases obtained from 22 hospitals in South Korea were examined.
Results:
A total of 413 cases of pcCD30-LPDs (lymphomatoid papulosis [LYP], n=237; primary cutaneous anaplastic large cell lymphoma [C-ALCL], n=176) were included. Ninety percent of LYP patients and roughly 50% of C-ALCL patients presented with multiple skin lesions. Both LYP and C-ALCL affected the lower limbs most frequently. Multiplicity and advanced T stage of LYP lesions were associated with a chronic course longer than 6 months. Clinical morphology with patch lesions and elevated serum lactate dehydrogenase were significantly associated with LPDs during follow-up in LYP patients. Extracutaneous involvement of C-ALCL occurred in 13.2% of patients. Lesions larger than 5 cm and increased serum lactate dehydrogenase were associated with a poor prognosis in C-ALCL. The survival of patients with C-ALCL was unaffected by the anatomical locations of skin lesions or other pathological factors.
Conclusion
The multiplicity or size of skin lesions was associated with a chronic course of LYP and survival among patients with C-ALCL.

Annals of Surgical Treatment and Research 2024;106(2):85-92
Purpose:
Anal wounds following hemorrhoidectomy can lead to severe pain and postoperative bleeding, impacting patient recovery and quality of life. Hyaluronic acid (HA) stimulates tissue regeneration and wound healing by accelerating cell migration and proliferation. This study aimed to investigate the differences in wound healing rate and completeness of recovery of perianal wounds topically treated with HA-soaked cotton in a murine model.
Methods:
Forty-eight 8-week-old Sprague-Dawley rats with perianal wounds created using a biopsy punch were divided into 2 groups: simple dressing with gauze (control) and topical HA-soaked cotton. A single application of HA-soaked cotton was administered after surgery. Wound healing rate and completeness of recovery were evaluated by measuring the healed area and conducting histological analyses.
Results:
The HA-cotton group exhibited a shorter complete wound healing duration compared to the control group (13.9 days vs. 16.4 days, P = 0.031). Differences in wound healing area between the 2 groups were greatest on postoperative day 2 (51.6% vs. 28.8%, P < 0.001). The HA-cotton group exhibited fewer cases of granulation tissue (2 vs. 5) or redness (0 vs.3) upon complete wound healing. Histologically, the HA-cotton group showed accelerated reepithelialization, rapid shift to lymphocyte-dominant inflammation, enhanced fibroblast proliferation, and increased collagen deposition compared to the control group.
Conclusion
Herein, topical application of HA-soaked cotton on perianal wounds in rats resulted in accelerated wound healing, particularly in the initial stages, and improved completeness of recovery, underscoring the potential of the topical application of HA-soaked cotton on hemorrhoidectomy wounds in human patients to improve wound healing.
