PURPOSE: The purpose of this study was to examine the effects of infection control education for families of patients infected with vancomycin resistant enterococcus (VRE). METHOD: Forty family members of VRE patients were chosen from a university hospital and assigned to the experimental or control group. The experimental group was provided infection control education that consisted of one-on-one instruction using an information booklet, hand-washing video, and demonstration of hand washing practice. Dependent variables were self-reported knowledge and performance of VRE infection control measures, and the number of hand washings when entering and leaving patients' rooms. RESULTS: Knowledge and performance scores were significantly higher for the experimental group compared to the control group. The experimental group washed their hands significantly more often when entering and leaving patients' rooms than the control group. CONCLUSION: Infection control education for family members of VRE patients was effective in improving knowledge and performance of infection control measures as well as improving the practice of hand washing. Further investigation is needed on the effects of infection control education for families on the actual VRE colonization and/or infection rate.

Collagenous fibroma (desmoplastic fibroblastoma) is a rare benign fibrous soft tissue tumor. This lesion commonly presents with painless, non-tender, mobile and slowly growing mass in subcutaneous tissue or skeletal muscle at various anatomic location. On magnetic resonance image (MRI), the mass shows area of low signal intensity on both T1- and T2-weighted pulse sequences. This low signal intensity presents areas of low cellularity in a background of abundant collagen. We describe the unique case of collagenous fibroma in the shoulder joint presenting with 4-years history of long-standing pain, which is unusual clinical manifestation of this benign soft tissue tumor without previous trauma history.

Background: Data on the association between coronavirus disease 2019 (COVID-19) and thyroid have been reported, including overt thyrotoxicosis and suppression of thyroid function. We aimed to evaluate the thyroid hormone profile and its association with the prognosis of COVID-19 in Korean patients. Methods: The clinical data of 119 patients with COVID-19, admitted in the Myongji Hospital, Goyang, South Korea, were retrospectively evaluated. The thyroid hormone profiles were analyzed and compared based on disease severity (non-severe disease vs. severe to critical disease). Clinical outcomes were analyzed according to the tertiles of thyroid hormones. Results: Of the 119 patients, 76 (63.9%) were euthyroid, and none presented with overt thyroid dysfunction. Non-thyroidal illness syndrome was the most common manifestation (18.5%), followed by subclinical thyrotoxicosis (14.3%) among patients with thyroid dysfunction. Thyroid stimulating hormone (TSH) and triiodothyronine (T3) levels were significantly lower in patients with severe to critical disease than in those with non-severe disease (P<0.05). Patients in the lowest T3 tertile (<0.77 ng/mL) had higher rates of mechanical ventilation, intensive care unit admission, and death than those in the middle and highest (>1.00 ng/mL) T3 tertiles (P<0.05). COVID-19 patients in the lowest T3 tertile were independently associated with mortality (hazard ratio, 5.27; 95% confidence interval, 1.09 to 25.32; P=0.038) compared with those in the highest T3 tertile. Conclusion Thyroid dysfunction is common in COVID-19 patients. Changes in serum TSH and T3 levels may be important markers of disease severity in COVID-19. Decreased T3 levels may have a prognostic significance in COVID-19 related outcome.

Somnambulism or sleepwalking is a disorder classified as non-rapid eye movement sleep parasomnia and is common in adolescents. Sleep fragmentation occurs frequently in somnambulism, and waking up and wandering are the main symptoms of the disorder. Our patient was a 14-year-old male with a 3-year history of sleepwalking at night when he visited our sleep clinic. A polysomnography was performed for the evaluation of parasomnia. Our patient was diagnosed as having parasomnia overlap syndrome with moderate obstructive sleep apnea (OSA). Continuous positive airway pressure (CPAP) therapy was prescribed for the OSA. After 12 weeks of CPAP, not only did the patient’s OSA symptoms resolve but somnambulism disappeared. Previous reports of overlap syndrome with OSA and somnambulism also supported the use of CPAP treatment for patients with both OSA and somnambulism.

Purpose: This study aims to explore the factors influencing nursing professionalism among nursing students, focusing on the image of nurses, satisfaction with their major, and career metacognition. Methods: We conducted a descriptive survey with 185 nursing students from D city and K region on June 10–30, 2024. Data were analyzed using IBM SPSS ver. 27.0 (IBM Corp.), employing descriptive statistics, t tests, one-way ANOVA, Scheffé tests, Pearson’s correlation coefficients, and regression analysis. Multiple linear regression analysis was used to identify factors affecting nursing professionalism among nursing students. Results: The regression analysis revealed that the image of nurses (β=.69, p<.001) and monitoring aspect of career metacognition (β=.13, p=.025) were significant predictors of nursing professionalism, accounting for 64.5% of the variance. Conclusion The findings indicate that the image of nurses and monitoring component of career metacognition are critical in shaping nursing professionalism among nursing students. Therefore, nursing education programs should aim to improve the image of nurses and promote self-reflective career practices as strategies to foster professionalism among nursing students.

PURPOSE: Vascular smooth muscle cell (VSMC) proliferation and extracellular matrix protein accumulation play important roles in chronic allograft vasculopathy. Mycophenolic acid (MPA) or rapamycin (RPM) was reported to inhibit VSMC proliferation in vitro and in vivo. However, effects of MPA or RPM on collagen synthesis of VSMCs, and the combined effects of MPA and RPM treatment on VSMC proliferation are not yet reported. METHODS: VSMCs isolated from the aorta of Sprague-Dawley rats were cultured with EMEM supplemented with 10% fetal bovine serum and insulin/ transferrin. Growth arrested and synchronized cells were pretreated with test drugs (alone or combination of various concentrations of MPA and RPM) 1 hour before the addition of 10 ng/ml PDGF. Cell proliferation was assessed by [H3]- thymidine incorporation, and collagen synthesis by [H3]- proline incorporation. RESULTS: PDGF increased cell proliferation and collagen synthesis by 3.4- and 2.1-fold, respectively, compared to control. MPA at above 100 nM or RPM at above 1 nM effectively inhibited PDGF-induced cell proliferation and collagen synthesis. The IC50 of MPA or RPM against PDGF-stimulated cell proliferation was between 100 nM and 1 micrometer or between 1 nM and 10 nM, respectively. The combination of MPA and RPM showed additive effects on PDGF-induced VSMC proliferation in a multiple regression analysis (R2=0.508, P<0.05). CONCLUSION: The present study demonstrated that MPA or RPM significantly inhibited PDGF-induced VSMC proliferation. These independent phenomena were well maintained as suggested by additive effects after combination treatment. PDGF-induced collagen synthesis was also effectively suppressed by the treatment of MPA or RPM.
