Purpose: We performed this study to determine how the emergency trauma team affects the treatment of patients with multiple severe trauma and to discuss the effect and the direction of the emergency trauma team's management. Methods: We performed a retrospective analysis of 518 patients who visited our emergency department with severe trauma from August 2006 to July 2008. We divided the severe trauma patients into 2 groups : patients before and after trauma team management (Group 1 and Group 2). Then, we compared demographic characteristics, mechanisms of injury, and treatment outcomes (lengths of stay in the ED, admission ratio, and in-hospital mortality) between the 2 groups. In the same way, patients with multiple severe trauma were divided into 2 groups, that are patients before and after trauma team management (Group 3 and Group 4) and analyzed. Results: There was no significant difference, except mean age, between groups 1 and 2. In group 4 patients, compared to group 3 patients, the lengths of stay in the ED were lower (p value < 0.001), and the admission ratio were higher (p value = 0.017), but there was no significant difference in the in-hospital mortality between the groups 3 and 4. Conclusion: When patients with multiple severe trauma visit the ED, the emergency trauma team' management can decrease the lengths of stay in the ED and increase the admission ratio, but does not produce a decrease in the in-hospital mortality rate. Further investigations of emergency trauma team management are needed to improve treatment outcomes for patients with multiple severe trauma.

Background: The number of heart transplantations (HTx) is increasing annually. Due to advances in medical and surgical support, the outcomes of HTx are also improving. Extracorporeal circulatory life support (ECLS) provides patients with decompensated heart failure a chance to undergo HTx. A medical approach involving collaboration among experienced experts in different fields should improve the outcomes and prognosis of ECLS-bridged HTx. Methods: From December 2003 to December 2018, 1,465 patients received ECLS at Samsung Medical Center. We excluded patients who had not undergone HTx or underwent repeated transplantations. Patients younger than 18 years were excluded. We also excluded patients who received an implantable durable left ventricular assist device before HTx. In total, 91 patients were included in this study. A multidisciplinary team approach began in March 2013 at our hospital. We divided the patients into 2 groups depending on whether they were treated before or after implementation of the team approach. Results: The 30-day mortality rate was significantly higher in the pre-ECLS team group than in the post-ECLS team group (n=5, 18.5% vs. n=2, 3.1%; p=0.023). The 1-year survival rate was better in the post-ECLS team group than in the pre-ECLS team group (n=57, 89.1% vs. n=19, 70.4%; p=0.023). Conclusion: We found that implementing a multidisciplinary team approach improved the outcomes of ECLS-bridged HTx. Team-based care should be adapted at HTx centers that perform high-risk HTx.

Purpose: To identify the effects of delivery-nursing simulation education using team-based learning on the delivery nursing knowledge, self-efficacy, and clinical competence of nursing students. Methods: The study used a nonequivalent, control group, quasi-experimental design. The team-based learning was applied to the experimental group, while the individual learning was applied to the control group. Data were collected from October 12 to December 7, 2016, and analyzed using the SPSS/WIN 22.0 program. Results: Comparison between the experimental and control group showed no significant difference in delivery-nursing knowledge (t=-0.33, p=.741) or self-efficacy (t=-0.65, p=.515). However, a significant difference (t=-2.09, p=.048) in the nursing-skills aspect of clinical competence was found between the experimental and control groups after the practical simulation education. Conclusion: Delivery-nursing simulation education using team-based learning was more effective in improving the nursing-skills aspect of nursing competence than was delivery-nursing simulation education based on individual learning.

Sibutramine is a serotonin-norepinephrine reuptake inhibitor indicated for the management of obesity in conjunction with a reduced calorie diet. The oral administration of sibutramine is followed by its dose-related side effects. In this study, sibutramine was formulated into drug in adhesive (DIA) patches in an attempt to overcome these problems. The effects of different formulation variables including pressure-sensitive adhesive (PSA), loading amount of drug, thickness of matrix and enhancer on the skin permeation of the drug were evaluated using excised hairless mouse skin. In the acrylic adhesive with carboxyl functional group, low release of sibutramine was observed due to the strong interaction between carboxyl group of adhesive and amine group of sibutramine. The acrylic adhesive without functional group provided good adhesion force and allowed high drug loading. Changing drug load as well as thickness of the matrix was found to alter permeation rate. $Crovol^{(R)}$ PK40 and $Crovol^{(R)}$ A40, were found to be effective enhancers for sibutramine. The optimized patch contained 20% sibutramine, and 5% $Crovol^{(R)}$ A40 as permeation enhancer, in $80\;{\mu}m$ thick Duro-$Tak^{(R)}$ 87-9301 matrix.

1, 1-dichloroethylene (DCE) is well known hepatotoxicant as a model acute hepatotoxicity and selectively injure the bile canalicular membrane of centrilobular hepatocytes. In this study, we investigated hepatic gene expression and histopathological changes in response to DCE treatment. DCE was administered once daily at 20 mg/kg up to 14 days via intraperitoneal injection. Five mice were used in each test group and were sacrificed at 1, 7, and 14 days. Serum biochemical and histopathological analysis were performed for evaluation of hepatotoxicity level. Direct bilirubin and total bilirubin activities were slightly elevated in treated group at 7 days. DCE treatment for 7 days resulted in centrilobular hepatocyte hypertrophy and hepatocyte vacuolation, and mild hepatocyte vacuolation and high hepatocyte basophilia were observed in 14 days treated group. One hundred twenty three up-regulated genes and 445 down-regulated genes with over 2-fold changes between treated and control group at each time point were used for pathway analysis. These data may contribute in understanding the molecular mechanism DCE-induced hepatotoxicity.

Objective: The aim of this study was to compare sling exercise group to McKenzie exercise group in patients with chronic neck pain. Design: Two group pretest-posttest design. Methods: Twenty subjects who have chronic neck pain were randomly divided into sling exercise group (n=10) and McKenzie exercise (n=10). Sling exercise group (n=10) received sling exercise for 30 minutes per day, twice a week over a 4 week period. And the other group were exercised McKenzie exercise (n=8) for 30 minutes per day, twice a week over a 4 week period. Neck disability index (NDI), Visual analog scale (VAS), algometer, digital manual muscle tester (MMT) and cervical muscle strength and cervical range of motion (ROM) are closely measured to identify the effect of sling exercise and McKenzie exercise. Results: For NDI, VAS, algometer on both trapezius, both rotation of cervical muscle strength, both lateral flexion of cervical muscle strength, cervical extension of ROM and both lateral flexion of ROM were significantly increased after intervention in sling exercise group (p<0.05), For VAS, algometer on both trapezius, left (Lt.) rotation of cervical muscle strength, Lt. lateral flexion of cervical muscle strength, cervical flexion and extension of ROM and Lt. lateral flexion of ROM were significantly increased after than before intervention in McKenzie exercise group (p<0.05). Conclusions: These study outcomes clearly support the notion that sling and McKenzie exercise improved pain, Muscle strength and ROM of patients with chronic neck pain. These results suggest that sling and McKenzie exercise program is suitable for chronic neck pain.
