PURPOSE: To investigate the change of the Beta adrenergic system in the rat visual cortex and superior colliculus after visual deprivation during a critical period of postnatal development. METHODS: The changes of beta 1 and beta 2 adrenergic receptor mRNA were investigated by using northern blot analysis in the rat visual cortex and superior colliculus. The right eyelid of visually deprived rat was sutured at the 10th postnatal days. After visual deprivation for 4 weeks, the rat were sacrificed and the visual cortex and superior colliculus tissues were removed for analysis. RESULTS: Beta 1 and beta 2 adrenergic receptor mRNA expression was decreased in the contralateral visual cortex to the deprived eye. In the superior colliculus, beta 2 adrenergic receptor mRNA expression increased in both sides, but a much greater increase was shown in the ipsilateral superior colliculus than the contralateral side. CONCLUSIONS: These results suggests that visual deprivation during a critical period of postnatal development influences the beta adrenergic system in the rat visual cortex and superior colliculus.

PURPOSE: The purpose of this study was to examine the effects of a cognitive behavioral stress management program on diabetic self-care and glycemic control with type 2 diabetic patients. METHODS: Thirty three diabetic patients who were older than 40 were recruited from a public health center and conveniently assigned into both experimental(n=16) and control groups(n=17). Participants in the experimental group had attended the weekly cognitive behavioral program for 8 weeks. Data were collected from June 2005 to August 2006 and analyzed by independent t-test using the SPSS WIN program. RESULTS: After an 8 week intervention, participants in the experimental group reported on increasement of diabetic self-care behaviors and an increasement of blood glucose levels, which were significantly different from those in the control group. CONCLUSION: On the basis of those findings, we concluded that the cognitive behavioral stress management program has positive effects on diabetic self-care and glycemic control for the patients with DM. Further research is needed to identify the long-term effects of the cognitive behavioral program.

Purpose: Cardio-cerebrovascular diseases constitute the most common and fatal disease among menopausal women. However, the risk of cardio-cerebrovascular diseases in menopausal women compared to men has been underestimated, with insufficient related studies. Therefore, we examined the incidence and risk factors of cardio-cerebrovascular diseases among Korean menopausal women. Methods: A retrospective observational study design with secondary analysis was conducted using data from the Korean Genome and Epidemiology Study survey. We used the study’s data of 1,197 menopausal women, aged 40–64 years, who did not have cardio-cerebrovascular diseases at baseline and their related data from the biennial follow-ups over 14 years. Cardio-cerebrovascular diseases were defined as hypertension, coronary artery disease, or stroke. The incidence of cardio-cerebrovascular diseases was calculated per person-years, and multivariate Cox proportional hazards models were used to determine the predictors of cardio-cerebrovascular diseases during the follow-up period. Results: Of the 1,197 cases, 264 were early or surgical menopausal women. The overall incidence of cardio-cerebrovascular diseases was 18.75 per 1,000 person-years. Early or surgical menopause (HR = 4.32, p < .001), along with family history of cardiovascular disease (HR = 1.87, p = .024), elevated blood pressure (HR = 1.79, p < .001), abdominal obesity (HR = 1.37, p = .046), or duration of menopause at the same age (HR = 1.01, p = .001), were strong predictors of cardio-cerebrovascular diseases. Conclusion Based on the results of this study, it is necessary to identify and closely monitor women with early or surgical menopause for cardiovascular and cerebrovascular diseases prevention. Also, prevention of cardio-cerebrovascular diseases through blood pressure and abdominal obesity management is vital for menopausal women.

This study aimed to derive insights into professional self-concept, teamwork, and job satisfaction among emergency department (ED) nurses and to prepare basic data for improving job satisfaction among ED nurses. Methods: The study was conducted between October 2023 and April 2024 at two certified tertiary hospitals and one general hospital in Gyeonggi-do, Korea, among 124 ED nurses. Data were analyzed using SPSS version 26.0, and the analysis included descriptive statistics, the t-test, Pearson correlation, and multiple regression. Results: The factors affecting job satisfaction in ED nurses were professional self-concept (β = .66, p < .001), teamwork (β = .17, p = .003), and ED work satisfaction (β = .17, p = .003), and the overall explanatory power of the model was 67.7%. Conclusion: This study makes a significant contribution by demonstrating that professional self-concept and teamwork can increase job satisfaction in ED nurses. Therefore, as a strategy to increase job satisfaction through improving ED nurses’ professional self-concept and teamwork, effort should be made to apply team simulation programs that provide education and self-improvement opportunities for frequent diseases and situations encountered in the ED, and to communicate effectively about patient treatment strategies.

PURPOSE: To investigate the peripapillary choroidal thickness (PCT) of polypoidal choroidal vasculopathy (PCV) and exudative age-related macular degeneration (AMD) and to evaluate their responses to anti-vascular endothelial growth factor (VEGF). METHODS: Thirty eyes with PCV and 25 eyes with exudative AMD who were treatment naïve were included in this study. PCT and subfoveal choroidal thickness were evaluated both before and after intravitreal anti-VEGF. RESULTS: The initial mean PCT of PCV (153.78 ± 56.23 µm) was thicker than that of exudative AMD (88.77 ± 23.11 µm, p < 0.001). Temporal, superior, nasal, and inferior PCTs of PCV were all thicker than those observedin exudative AMD (all p < 0.05). After anti-VEGF, the mean PCT of PCV was significantly reduced (134.17 ± 41.66 µm, p < 0.001), but the same was not true not in exudative AMD (86.87 ± 22.54 µm, p = 0.392). PCTshowed a similar tendency in all quadrants. CONCLUSIONS: PCV exhibits a thick choroid in the peripapillary region. PCT decreases after anti-VEGF in PCV but not in exudative AMD. In exudative AMD, subfoveal choroidal thickness decreased, but that in the peripapillary region did not.

A 52-year-old woman with a history of general weakness, fatigue, weight loss, elevated serum levels of liver transaminase enzyme for three months underwent an F-18 FDG PET/CT scan to evaluate a cause of the hepatosplenomegaly found on abdominal ultrasonography. Initial PET/CT revealed markedly enlarged liver and spleen with intense FDG uptake. Otherwise, there were no areas of abnormal FDG uptake in whole body image. Histological evaluation by a hepatic needle biopsy demonstrated diffuse large B cell type lymphoma and final diagnosis for this patient was hepatosplenic B-cell lymphoma. She received five cycles of CHOP chemotherapy, and second PET/CT scan was followed after then. Follow-up PET-CT revealed normal sized liver with disappearance of abnormal FDG uptake. Hepatosplenic B-cell lymphoma is relatively rare and mostly presents as single or multiple nodules.1,2 Diffuse type hepatosplenic lymphoma is extremely rare and poorly recognized entity.3 The diagnosis is very difficult and complicated by the presence of misleading symptoms.4 In this rare hepatosplenic B-cell lymphoma case, F-18 FDG PET/CT scan provided a initial diagnostic clue of hepatosplenic lymphoma and an accurate chemotherapy response.

STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the prevalence and associated factors of the concurrent lower thoracic lesions in patients who have a lumbar spine disease, using the extended lumbar MRI. SUMMARY OF LITERATURE REVIEW: There are no studies regarding the concurrent thoracic lesions with lumbar disease. MATERIALS AND METHODS: All the patients, who had visited the out-patient department (OPD) of orthopaedic surgery in our hospital and underwent lumbar spine MRI, were studied during 1 year. Totally, 750 patients were included. The extended lumbar spine MRI contained additional extended T2-weighted sagittal images that cover the lower thoracic vertebrae with 35 centimeters long. We analyzed the highest observable level, characteristics of detected thoracic lesions. Those lesions were classified according to the severity of compression of the spinal cord and investigation for associated factors of patients. Also, the times for additional tests were measured. RESULTS: Additional tests were able to observe up to the 7th thoracic vertebrae. In 257 cases (34.3%), the lower thoracic lesions were detected and increased with aging (p<0.001). A total of 48 patients (6%) had the lesion compressing the spinal cord and 28 patients needed further evaluation for the lower thoracic lesion. Further, 2 cases were treated surgically for lower thoracic lesions. Scanning extra time for additional test were 3 minutes. CONCLUSIONS: The prevalence of lower thoracic lesions accompanied with the lumbar disease was 34% in this study. Therefore, additional extended lumbar spine MRI is needed to check possible concurrent lesions in the lower thoracic spine.
