PURPOSE: This study investigated attitudes toward general elders and elders with dementia among nursing students before beginning the clinical practicum. In addition, students' characteristics differentiating the attitudes were examined. METHODS: Attitudes were measured with questionnaires developed for Asian culture at the beginning week of the first semester of the junior year in two baccalaureate programs. Responses from 120 out of 121 students were analyzed using Pearson correlation coefficient, paired t-test, ANOVA, and Scheffe test. RESULTS: Students held negative attitudes toward both types of elders except for generosity dimension toward general elders showing a neutral attitude. Elders with dementia were evaluated more negatively than general elders in all the dimensions of vitality, generosity and flexibility. Vitality and generosity toward general elders were different according to intimacy and the degree of communication with elders. Generosity toward general elders was also different according to students' religious beliefs. Students with interest in elders/issues showed more negative attitudes of vitality and flexibility toward elders with dementia. CONCLUSIONS: Students in general had negative attitudes toward elders and more negative attitudes toward elders with dementia. We need to put more efforts into the entire nursing curriculum in order to improve attitudes toward elders with particular concern over attitudes toward elders with dementia.

PURPOSE: This study investigated changes in attitudes toward elders in general and elders with dementia after students finished a gerontological nursing practicum. METHODS: Questionnaires developed for Asian cultures were administered pre practicum, immediately post practicum, and at 8-months follow up to 31 senior students in a baccalaureate nursing program. The 1-week practicum occurred at two adult day care centers: a center for elders with dementia and a center for elders with stroke. Repeated measures ANOVA and Bonferroni correction procedures were used to analyze data. RESULTS: Students' evaluation of elder vitality and flexibility increased significantly at post practicum, however this increase was not sustained at follow up. Score of generosity of elders, the only positively evaluated dimension for elders in general, improved partly at post practicum. Students evaluated flexibility and generosity of elders with dementia more negatively than general elders. All of the decreased attitudes at follow up were not significantly different from those at pre practicum. CONCLUSIONS: Students had more negative attitudes toward elders with dementia. Attitudes of students in direct contact with elders with dementia were improved through the practicum regarding generosity and flexibility. However the sustainability of the immediate effect was not observed at follow up.

Myasthenia gravis (MG) is an antibody-mediated autoimmune disease characterized by exertional weakness. There is no biomarker to reflect disease activity and guide treatment decision. Here, we reported a pilot blood transcriptome study using RNA sequencing (RNA-seq) that identified differences of 5 samples in active status and 5 in remission from 8 different patients and 2 patients provided samples for both active and remission phase. We found a total of 28 differentially expressed genes (DEGs) possibly related to disease activity (23 up-regulated and 5 down-regulated). The DEGs were enriched for the cell motion and cell migration processes in which included were ICAM1, CCL3, S100P and GAB2. The apoptosis and cell death pathway was also significantly enriched, which includes NFKBIA, ZC3H12A, TNFAIP3, and PPP1R15A. Our result suggests that transcript abundance profiles of the genes involved in cell trafficking and apoptosis may be a molecular signature of the disease activity in MG patients.

Guillain-Barre syndrome is an acute inflammatory demyelinating polyradiculopathy characterized by progressive motor weakness, areflexia, and ascending paralysis. Guillain-Barre syndrome is extremely rare in pregnant patients, and there are no established guidelines for delivery or safest anesthetic methods. We report a Cesarean delivery in the case of a 32-year old woman who was diagnosed with Guillain-Barre syndrome 18 weeks into gestation. Tracheostomy was performed due to progressive respiratory muscle weakness and respiratory failure, and ventilator support was required in the intensive care unit. The respiratory difficulty was exacerbated by the growth of the fetus, necessitating emergency Cesarean delivery. The delivery was successfully performed under general anesthesia, and the patient recovered without neurological sequelae.

PURPOSE: This study was designed to assess the types of nursing organizational culture, and degree of self-leadership and burnout as perceived by perioperative nurses, and to identify correlations between these variables. METHODS: Participants were 155 nurses from 3 tertiary hospitals in Seoul and data were analyzed using descriptive statistics, ANOVA, Scheffé, and Pearson correlation coefficient. RESULTS: In the types of nursing organizational culture, the mean score for hierarchy-oriented culture was 3.57, and for self-leadership, 3.61 and for burnout, 2.87. In the relationship between the types of nursing organizational culture, self-leadership and burnout, relation-oriented culture (r=.24, p<.01), innovation-oriented culture (r=.23, p<.01) and task-oriented culture (r=.22, p<.01) had a slight positive correlation with self-leadership in that order. The innovation-oriented culture (r=-.29, p<.01) and relation-oriented culture (r=-.42, p<.01) among the types of nursing organizational culture showed a negative correlation with burnout while the hierarchy-oriented culture (r=.28, p<.01) showed a positive correlation with burnout. Self-leadership showed a negative correlation with burnout (r=-.42, p<.01). CONCLUSION: The results show that nurses in operating rooms have a high awareness of hierarchy-oriented culture that affects burnout in a negative way while having a low awareness of relation-oriented culture that has a positive influence on burnout.

Retrobulbar block is commonly performed under monitored anesthesia prior to cataract surgery. Known complications associated with retrobulbar block include cranial nerve palsies, seizures, and cardiorespiratory arrest. We report a case of severe shivering following a retrobulbar block. Two minutes after the block was administered, the patient experienced severe shivering, which subsided after injection of pethidine 25 mg. The likely etiology of the shivering was inadvertent dural puncture of the optic nerve sheath and local anesthetic spread into the cerebrospinal fluid space. Shivering may be a warning sign of brain stem anesthesia, and in such a scenario the clinician should direct special attention to possible life-threatening complications.

Recently, social cognition is becoming a hot issue in field of schizophrenia research. There are increasing demands for more clear definition of terms and knowledge about neurobiology of social cognition in schizophrenia. One of the reasons why it receives so much attention would be its role of predicting the functional outcomes of schizophrenia patients. The purpose of this article is to review and summarize the concepts and neural correlates of social cognition in schizophrenia. Functional brain imaging studies as well as behavioral studies were reviewed.

Eight Beagle dogs were anesthetized and were imaged using a single channel helical CT scanner. The contrast medium used in this study was iohexol (300 mg I/ml) and doses were 0.5 ml/kg for a cine scan, 3 ml/kg for an enhanced scan. The flow rate for contrast material administration was 2 ml/sec for all scans. This study was divided into three steps, with unenhanced, cine and enhanced scans. The enhanced scan was subdivided into the arterial phase and the venous phase. All of the enhanced scans were reconstructed in 1 mm intervals and the scans were interpreted by the use of reformatted images, a cross sectional histogram, maximum intensity projection and shaded surface display. For the cine scans, optimal times were a 9-sec delay time post IV injection in the arterial phase, and an 18-sec delay time post IV injection in the venous phase. A nine-sec delay time was acceptable for the imaging of the canine hepatic arteries by CT angiography. After completion of arterial phase scanning, venous structures of the liver were well visualized as seen on the venous phase.

Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) mapping are functional magnetic resonance imaging techniques for detecting water diffusion. DWI and the ADC map were performed for intracranial lesions in two dogs. In necrotizing leukoencephalitis, cavitated lesions contained a hypointense center with a hyperintense periphery on DWI, and hyperintense signals on the ADC maps. In metastatic sarcoma, masses including a necrotic region were hypointense with DWI, and hyperintense on the ADC map with hyperintense perilesional edema on DWI and ADC map. Since DWI and ADC data reflect the altered water diffusion, they can provide additional information at the molecular level.
