Purpose: This study examined the impact of professional Quality of life (QoL) on turnover intention among general hospital nurses using linear and nonlinear analytical techniques. Methods: Data were collected from 159 general hospital nurses and analyzed using SPSS, t-test, ANOVA, Pearson's correlation coefficients, multiple linear regression, and nonlinear machine learning models (Bootstrap Forest and Boosted Tree). Results: Significant correlations were observed between turnover intention and both compassion satisfaction (r=-.26, p<.001) and burnout (r=.27, p=.001). Compassion satisfaction, burnout, and compassion fatigue were identified as the key variables influencing turnover intention. The explanatory power of multiple linear regression analysis was 6.9%, whereas the nonlinear machine learning models demonstrated an explanatory power of 50.5% for Bootstrap Forest and 45.1% for Boosted Tree. Conclusion Continuous investment in human resource management, within nursing organizations, is essential to promote the long-term retention of general hospital nurses. This investment should focus on enhancing compassion satisfaction and reducing burnout and compassion fatigue by fostering a sense of vocation and positive job satisfaction.

Objective: : Korea’s healthcare system and policy promotes early, actively stroke treatment to improve prognosis. This study represents stroke epidemiology and outcomes in Korea. Methods: : This study investigated data from the Acute Stroke Assessment Registry. The registry collects data from over 220 hospitals nationwide, focusing on quality stroke service management. Data analysis included patient demographics, stroke severity assessment, and discharge prognosis measurement using standardized scales. Results: : Eighty-six thousand five hundred sixty-eight acute stroke patients were collected with demographic and clinical characteristics during 18 months from 2016, 2018, and between 2020 to 2021, focusing on acute subarachnoid hemorrhage (SAH), acute intracerebral hemorrhage (ICH), and acute ischemic stroke. Of these 86568 patients, 8.3% was SAH, 16.3% ICH, and 74.9% ischemic stroke. Trends showed decreasing SAH and increasing ICH cases over the years. 68.3% stroke patients had the clear onset time. 49.6% stroke patients arrived within 4.5 hours of symptom onset, with more patients treated at general hospitals. Good functional outcomes at discharge was obtained with 58.3% of acute stroke patients, 55.9% of SAH patients, 34.6% of ICH patients, and 63.8% of ischemic stroke patients. Conclusion : The results showed that ischemic stroke was the most common subtype, followed by ICH and SAH. Prognosis differed among subtypes, with favorable outcomes more common in ischemic stroke and SAH compared to ICH.

To ensure high-quality bioresources and standardize biobanks, there is an urgent need to develop and disseminate educational training programs in accordance with ISO 20387, which was developed in 2018. The standardization of biobank education programs is also required to train biobank experts. The subdivision of categories and levels of education is necessary for jobs such as operations manager (bank president), quality manager, practitioner, and administrator. Essential training includes programs tailored for beginner, intermediate, and advanced practitioners, along with customized training for operations managers. We reviewed and studied ways to develop an appropriate range of education and training opportunities for standard biobanking education and the training of experts based on KS J ISO 20387. We propose more systematic and professional biobanking training programs in accordance with ISO 20387, in addition to the certification programs of the National Biobank and the Korean Laboratory Accreditation System. We suggest various training programs appropriate to a student’s affiliation or work, such as university biobanking specialized education, short-term job training at unit biobanks, biobank research institute symposiums by the Korean Society of Pathologists, and education programs for biobankers and researchers. Through these various education programs, we expect that Korean biobanks will satisfy global standards, meet the needs of users and researchers, and contribute to the advancement of science.

Background and Objectives: Outcomes of deferring percutaneous coronary intervention (PCI) without invasive physiologic assessment for intermediate coronary lesions is uncertain.We sought to compare long-term outcomes between medical treatment and PCI of intermediate lesions without invasive physiologic assessment. Methods: A total of 899 patients with intermediate coronary lesions between 50% and 70% diameter-stenosis were randomized to the conservative group (n=449) or the aggressive group (n=450). For intermediate lesions, PCI was performed in the aggressive group, but was deferred in the conservative group. The primary endpoint was major adverse cardiac events (MACE, a composite of all-cause death, myocardial infarction [MI], or ischemia-driven any revascularization) at 3 years. Results: The number of treated lesions per patient was 0.8±0.9 in the conservative group and 1.7±0.9 in the aggressive group (p=0.001). At 3 years, the conservative group had a significantly higher incidence of MACE than the aggressive group (13.8% vs. 9.3%; hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.00–2.21; p=0.049), mainly driven by revascularization of target intermediate lesion (6.5% vs. 1.1%; HR, 5.69; 95% CI, 2.20–14.73;p<0.001). Between 1 and 3 years after the index procedure, compared to the aggressive group, the conservative group had significantly higher incidence of cardiac death or MI (3.2% vs.0.7%; HR, 4.34; 95% CI, 1.24–15.22; p=0.022) and ischemia-driven any revascularization. Conclusions For intermediate lesions, medical therapy alone, guided only by angiography, was associated with a higher risk of MACE at 3 years compared with performing PCI, mainly due to increased revascularization.

Background: Syphilis, an infectious and chronic disease primarily transmitted through sexual contact, is caused by the spirochete bacterium Treponema pallidum. Although the introduction of penicillin has significantly reduced its incidence, syphilis continues to have a substantial impact on public health. Objective: The purpose of this study was to investigate trends in syphilis and to analyze its epidemiologic, clinical, and serologic characteristics. Methods: We retrospectively reviewed the medical records of 330 patients who tested positive for the Venereal Disease Research Laboratory (VDRL) test, including 192 patients who received a diagnosis of syphilis and who visited the Dermatology Department of Gachon University Gil Medical Center between 2000 and 2023. Statistical analyses were performed to evaluate trends in syphilis incidence and related variable factors, such as sex, age, and serological results. Results: The average age of the 192 syphilis patients was 34.18±15.81 years, with a male-to-female ratio of 1:1.2. The most prevalent age group was 20∼29 years, comprising 71 patients (37.0%). Over time, the incidence of syphilis demonstrated a decreasing trend (p＜0.001). A total of 105 patients (54.7%) were diagnosed with symptomatic syphilis, with a male-to-female ratio of 1.5:1. The proportion of symptomatic syphilis patients tended to decrease with increasing age (p＜0.05). Maculopapular syphilis was the most frequently observed presentation in secondary syphilis (36.2%). The proportion of symptomatic syphilis patients significantly increased with higher VDRL titers (p＜0.001). Conclusion The incidence of syphilis has shown a consistent decline over the past two decades. However, the relatively higher prevalence among younger age groups indicates the need for continued public health efforts.

Regorafenib is an oral multikinase inhibitor used to treat advanced solid tumors, including hepatocellular carcinoma (HCC), gastrointestinal stromal tumors, and colorectal cancer. Adverse dermatological reactions are common after regorafenib treatment. The most frequent cutaneous adverse reaction is hand-foot skin reaction (HFSR). Compared to HFSR, reports on adverse reactions on the scrotum associated with regorafenib are limited. Only a few cases of adverse reactions on the scrotum associated with HFSR have been reported. We present the case of a 55-year-old male patient with a 1-year history of scrotal dermatitis and HFSR, who had been undergoing treatment for HCC.One year after administration of oral regorafenib (160 mg/d), multiple vesicles, pustules, desquamation, and hyperkeratosis developed on both hands and feet, accompanied by scaly erythematous plaques around the scrotum.The lesions improved after two weeks of treatment with topical and systemic steroids. Herein, we report a rare case of scrotal dermatitis associated with regorafenib-induced HFSR.
