PURPOSE: The aim of this study was to identify the effects of organizational culture and organizational support on the innovative behavior of general hospital nurses. METHODS: The participants in this study were 356 nurses, working in hospitals in Seoul, Gyeonggi and Gangwon Provinces, and Daejeon City. Data were collected from June to August, 2012. A structured questionnaire was used for data collection and data was analyzed using the SPSS/WIN program. RESULTS: The organizational culture positively correlated with innovative behavior. The most significant predictors of innovative behavior were age, organizational support and hierarchy-oriented culture. CONCLUSION: These findings suggest that nurses' organizational culture and organizational support were linked to innovative behavior. Management-level workers in these hospitals should have the skills and strategies to develop nurses' innovative behavior and increases nurses' recognition of organizational support to achieve high performance through innovation.

BACKGROUND: This study aims to analyze the effects of insurance types on the medical service uses for heart failure inpatients using propensity score matching (PSM). METHODS: 2014 National inpatient sample based on health insurance claims data was used in the analysis. PSM was applied to control factors influencing the service uses except insurance types. Negative binomial regression was used after PSM to analyze factors that had influences on the service uses among inpatients. Subjects were divided by health insurance type, national health insurance (NHI) and medical aid (MA). Total charges and length of stay were used to represent the medical service uses. Covariance variables in PSM consist of sociodemographic characteristics (gender, age, Elixhauser comorbidity index) and hospital characteristics (hospital types, number of beds, location, number of doctors per 50 beds). These variables were also used as independent variables in negative binomial regression. RESULTS: After the PSM, length of stay showed statistically significant difference on medical uses between insurance types. Negative binomial regression provided that insurance types, Elixhauser comorbidity index, and number of doctors per 50 beds were significant on the length of stay. CONCLUSION: This study provided that the service uses, especially length of stay, were differed by insurance types. Health policy makers will be required to prepare interventions to narrow the gap of the service uses between NHI and MA.

In canine acute pancreatitis (AP), inappropriate release and activation of zymogen proteases within the pancreas results in the consumption of serum antiproteases. The aim of this study was to examine whether the serum concentrations of α₂-macroglobulin (A2MG), α₁-antitrypsin (A1AT), and C-reactive protein (CRP) differ between dogs with AP and healthy dogs. Twenty healthy dogs and 20 dogs with AP were included in this study. Concentrations of A2MG, A1AT, and CRP were measured in the sera of healthy dogs and dogs diagnosed with AP. Serum A2MG and A1AT concentrations were significantly lower in dogs with AP than in healthy dogs, whereas the serum CRP concentration was significantly higher. In addition, the concentrations of A2MG and A1AT were significantly higher in AP survivors than in AP non-survivors, while the CRP concentration was significantly lower. However, in both AP survivors and non-survivors, the CRP concentrations showed a negative correlation with A2MG concentrations but not with A1AT. These findings indicate that serum antiproteases and CRP concentrations might be associated with the mortality rate of AP in dogs.

BACKGROUND: Dendritic cell (DC)-based cancer immunotherapy is studied for several years. However, it is mainly derived from autologous PBMC or leukapheresis from patient, which has limitations about yield and ability of DC production according to individual status. In order to solve these problems, inquiries about allogeneic DCs are performed but there are no preclinical trial answers for effect or toxicity of allogeneic DC to use for clinical trial. In this study, we compared the anti-tumor effect of allogeneic and autologous DCs from mouse bone marrow stem cells in mouse metastatic melanoma model. METHODS: B16F10 melanoma cells (5 x 10(4)/mouse) were injected intravenously into the C57BL/6 mouse. Therapeutic DCs were differentiated from autologous (C57BL/6: CDC) or allogeneic (B6C3F1: BDC) bone marrow stem cells with GM-CSF, SCF and IL-4 for 13days and pulsed with B16F10 tumor cell lysate (Blys) for 18hrs. DC intra-peritoneal injections began on the 8th day after the tumor cell injection by twice with one week interval. RESULTS: Anti-tumor response was observed by DC treatment without any toxicity especially in allogeneic DC treated mice (tumor burden score: 2.667+/-0.184, 2.500+/-0.463, 2.000+/-0.286, 1.500+/-0.286, 1.667+/-0.297 for saline, CDC/unpulsed-DC: U-DC, CDC/Blys-DC, BDC/U-DC and BDC/Blys-DC, respectively). IFN-gamma secretion was significantly increased in allogeneic DC group stimulated with B16F10 cell lysate (2,643.3+/-5,89.7, 8,561.5+/-2,204.9. 6,901.2+/-141.1 pg/1 x 10(6) cells for saline, BDC/U-DC and BDC/Blys-DC, respectively) with increased NK cell activity. CONCLUSION: Conclusively, promising data was obtained that allogeneic DC can be used for DC-based cancer immunotherapy.

BACKGROUND: Tumor cell lysate has been considered as a preferential antigen source for the therapeutic dendritic cell pulsing. Our experiences with in vivo study with animal tumor model indicate the tumor cell lysate dependent differential effect of DC therapy. Our previous data show that MC38 lysate pulsed-DC induced stronger ag-specific immunity than CT26 lysate pulsed-DC in vitro. In this study we tried to reveal the mechanism for differential induction of ag-specific immunity of different colon cancer cell lysate pulsed-DCs. METHODS: MC38 and CT26 cell lines were prepared as lysate by freezing-thawing procedure. Tumor cell antigenicity was confirmed by detecting the surface expression of MHC I/II & B7.1/2 molecules. IL-10, IL-12 and TGF-beta in the tumor cell lysate were detected by ELISA and the presence of heat shock proteins were analysed by western blotting. RESULTS: The secretion of IL-10, a immune-inhibitory cytokine was about 470% higher in CT26 lysate than in MC38. Hsp 70 was detected only in the MC38 lysate but not in the CT26. On the other hand, Hsp 60 and 90 expression were not different in two colon cancer cell lysates. CONCLUSION: In two different colon caner cell lysate, immune inhibitory IL-10 (higher in CT26) and Hsp70 (MC38 superiority) were differentially expressed. These data indicate that higher ag- specific immunity induction by MC38 lysate pulsed-DC may due to the expression of hsp70 and lower secretion of IL-10, a immune-inhibitory cytokine than CT26 lysate. The significance of other cytokine and the surface marker expression will be discussed.

Kallmann's syndrome is a rare condition, and this is defined as hypogonadotropic hypogonadism and anosmia or hyposmia. The syndrome may be associated with cleft lip, cleft palate, color blindness, skeletal abnormalities, renal agenesis, sensory neural hearing loss, obesity, etc. About 10 cases of Kallmann's syndrome have been reported in Korea, but there are no reports on cases of Kallmann's syndrome with atrophy of the frontal lobe, severe mental retardation and unilateral renal agenesis. We experienced a case of 17-year-old boy with abnormalities of the olfactory system, as was noted on magnetic resonance imaging (MRI). He had an atrophy of the frontal lobe, mental retardation, a micropenis and unilateral renal agenesis. Hormonal assay documented low levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), testosterone and thyroid-stimulating hormone (TSH). So, we report here on an unusual case of Kallmann's syndrome along with briefly reviewing the relevant medical literature.

Although chronic myelogenous leukemia (CML) may be involved in any part of the body, infiltration of the body fluid has rarely reported in the literature. Here we report on a 35 year-old male patient who was diagnosed chronic myelogenous leukemia ten years previously and he received allogenic hematopoietic stem cell transplantation. He then presented with left knee pain eight years after the initial diagnosis. MRI revealed a soft tissue mass at the distal femur. Cytology of the joint fluid revealed myeloblasts, promyelocytes, eosinophilic myelocytes, band neutrophils, megakaryocytes and orthochromatic erythroblasts, which was all consistent with leukemic infiltration of the knee joint fluid. The immunohistochemistry was positive for CD34, CD117 and myeloperoxidase (MPO). Despite that the patient underwent radiation therapy, MRI revealed growth of the mass, and ten months later, the lymphoid blast phase of CML was confirmed after biopsy. The patient received an above knee amputation. Five months later, multiple masses were revealed on PET-CT at the left iliopsoas muscle, abdominal wall and bones. Bilateral pleural effusion occurred shortly after this. Cytologic evaluation of the pleural fluid also revealed blast-like cells, and histologic evaluation of the abdominal mass confirmed the lymphoid blast phase of CML with positivity for CD3, UCHL-1, CD34 and CD117, but negativity for MPO.

OBJECTIVES: The aim of this study was to determine whether children with Tourette disorder (TD) have functional impairment and executive dysfunction in comparison to children with attention-deficit hyperactivity disorder (ADHD) and non-affected controls. METHODS: From January 2006 to December 2013, 45 children and adolescents with TD and 50 children and adolescents with ADHD diagnosed at the Soonchunhyang University Bucheon Hospital and 50 non-affected controls were enrolled in this study. Functional impairment of the subjects was assessed using the Child and Adolescents Functioning Impairment Scale (CAFIS), parent and teacher versions. In addition, neuropsychological tests including Stroop color-word Test, Finger windows Test (FWT), and Digit span were administered. Outcomes were compared across the TD, ADHD, and non-affected controls. RESULTS: No difference in CAFIS-parent and CAFIS-teacher results was observed between children with TD and non-affected controls, whereas, children with ADHD showed more impairments relative to non-affected controls in the CAFIS-parent. According to the Stroop color-word Test, FWT, and Digit span, executive function in children with TD did not differ from non-affected controls. Children with ADHD had poorer performance in measures of the Stroop color-word Test compared to children with TD. CONCLUSION: Children and adolescents with TD but not ADHD were not significantly different from non-affected controls on most measures of functional impairment and executive function. These findings suggest that an education program and intervention for children with TD would be important to reducing the stigma of TD.
