PURPOSE: The purpose of this study was to identify the predictors of clinical competence in new graduate nurses. METHODS: The subjects of this study were 238 nurses at 13 general hospitals who have had less than 12 months of nursing experience. The data were collected by structured questionnaire from August 5 to August 31 of 2009 and analyzed by the SPSS Win 12.0 program. RESULTS: The total mean score for clinical competence was 181.05+/-15.17, critical thinking disposition was 94.65+/-8.12, and practice environment was 41.00+/-5.55. There were significant differences of clinical competence according to the GPA (t=-3.58, p<.001), the number of beds in the hospital (t=-3.22, p=.001), instruction by preceptor (t=-2.32, p=.021), and previous experience of clinical practice in the hospital (t=-2.21, p=.028). Additionally, critical thinking disposition and practice environment were positively correlated to clinical competence (r=.50, p<.001; r=.20, p=.002). In multivariate approach, predictors included in this study explained 43% of variance in clinical competence. Significant predictors of clinical competence were critical thinking disposition (beta=.50, p<.001), practice environment (beta=.14, p=.012), and working duration (beta=.13, p=.018). CONCLUSIONS: Based on these findings, it is needed that providing supportive practice environment and developing curriculum for enhancing the critical thinking disposition to improve the clinical competence in new graduate nurses.

BACKGROUND: Critical care physician staffing is a crucial element of the intensive care unit (ICU) organization, and is associated with better outcomes in ICUs. Adult ICUs in Korea have been suffering from inadequate full-time intensivists and nurses because of insufficient reimbursement rates (<50% of the original critical care cost) from the National Health Insurance System. Recently, full-time intensivists have been introduced as a prerequisite for adult ICUs of tertiary hospitals in Korea. The purpose of this study was to examine the perception of intensivist staffing among critical care program directors regarding the barriers and solutions when implementing an intensivist model of critical care in Korea. METHODS: An email survey of critical care program directors in designated teaching hospitals for critical care subspecialty training by the Korean Society of Critical Care Medicine was performed. The survey domains included vision, culture, resources, barriers, and potential solutions to implementing intensivist physician staffing (IPS). RESULTS: Forty-two critical care program directors were surveyed. A total of 28 directors (66.7%) responded to email queries. Of these, 27 directors (96.4%) agreed that IPS would improve the quality of care in the ICU, although half of them reported a negative perception of relevant clinical colleagues for the role of full-time intensivists and poor resources for IPS in their hospitals. Increased financial burden due to hiring full-time intensivists and concerns regarding exclusion from the management of their critically ill patients in the ICU, together with loss of income for primary attending physicians were stated by the respondents to be major barriers to implementing IPS. Financial incentives for the required cost from the health insurance system and enhancement of medical law relevant to critical care were regarded as solutions to these issues. CONCLUSIONS: Critical care program directors believe that intensivist-led critical care can improve the outcome of ICUs. They indicated the financial burden due to IPS and underestimation of a full-time intensivist's role to be major barriers. The program directors agreed that a partnership between hospital leaders and the Ministry of Health and Welfare was needed to overcome these barriers.

The research of p53 is being conducted to find the mechanisms of tumorigenesis and to treat various cancers. Homeodomain-interacting protein kinase2 (HIPK2) is an important factor to regulate p53 and to increase the stability of p53. Activation of HIPK2 leads to the selective phosphorylation of p53, resulting in growth arrest and the enhancement of apoptosis. In this study, the canine HIPK2 cDNA fragments were obtained, and their overlapping regions were aligned to give a total sequence of 3489 bp. The canine HIPK2 cDNA (GenBank accession number; AY800385) shares 93% and 90% sequence identity with those of human and mouse HIPK2, respectively. The canine HIPK2 cDNA contains an open reading frame encoding 1163 amino acid residues and the predicted amino acid sequence has 98% and 96% identity with those of human and mouse, respectively. The deduced amino acid sequence of canine HIPK2 has also all domains' sites compared with human and mouse HIPK2. Therefore, these structural similarities suggested that the canine HIPK2 shares the basic biological functions that HIPK2 exhibit in other species.

OBJECTIVE: We retrospectively evaluated the effectiveness of the esophageal balloon dilatation (EBD) in children with a corrosive esophageal stricture. MATERIALS AND METHODS: The study subjects included 14 patients (M:F = 8:6, age range: 17-85 months) who underwent an EBD due to a corrosive esophageal stricture. The causative agents for the condition were glacial acetic acid (n = 9) and lye (n = 5). RESULTS: A total of 52 EBD sessions were performed in 14 patients (range 1-8 sessions). During the mean 15-month follow-up period (range 1-79 months), 12 patients (86%) underwent additional EBD due to recurrent esophageal stricture. Dysphagia improved after each EBD session and oral feeding was possible between EBD sessions. Long-term success (defined as dysphagia relief for at least 12 months after the last EBD) was achieved in two patients (14%). Temporary success of EBD (defined as dysphagia relief for at least one month after the EBD session) was achieved in 17 out of 52 sessions (33%). A submucosal tear of the esophagus was observed in two (4%) sessions of EBD. CONCLUSION: Only a limited number of children with corrosive esophageal strictures were considered cured by EBD. However, the outcome of repeated EBD was sufficient to allow the children to eat per os prior to surgical management.

Due to the therapeutic potential of gene therapy for neuronal injury, many studies of neurotrophic factors, vectors, and animal models have been performed. The presumed dog beta-nerve growth factor (pdbeta-NGF) was generated and cloned and its expression was confirmed in CHO cells. The recombinant pdbeta-NGF protein reacted with a human beta-NGF antibody and showed bioactivity in PC12 cells. The pdbeta-NGF was shown to have similar bioactivity to the dog beta-NGF. The recombinant pdbeta-NGF plasmid was administrated into the intrathecal space in the gene therapy group. Twenty-four hours after the vector inoculation, the gene therapy group and the positive control group were intoxicated with excess pyridoxine for seven days. Each morning throughout the test period, the dogs' body weight was taken and postural reaction assessments were made. Electrophysiological recordings were performed twice, once before the experiment and once after the test period. After the experimental period, histological analysis was performed. Dogs in the gene therapy group had no weight change and were normal in postural reaction assessments. Electrophysiological recordings were also normal for the gene therapy group. Histological analysis showed that neither the axons nor the myelin of the dorsal funiculus of L(4) were severely damaged in the gene therapy group. In addition, the dorsal root ganglia of L(4) and the peripheral nerves (sciatic nerve) did not experience severe degenerative changes in the gene therapy group. This study is the first to show the protective effect of NGF gene therapy in a dog model.

Spontaneous rupture of renal artery aneurysm is a rare, but life threatening complication with high mortality. The etiology of non-traumatic renal artery aneurysm is fibromuscular dysplasia, atherosclerosis, vasculitis, and pregnancy. We here report a case of spontaneous rupture of renal artery aneurysm in a patient with untreated hypertension. A 39-year-old non-pregnant woman complained of sudden onset of right flank and lower quadrant abdominal pain. Ultrasonography showed large fluid collection in right lower abdomen. Emergency laparotomy demonstrated huge retroperitoneal hematoma due to spontaneous rupture of right renal artery aneurysm. Microscopic examination of the aneurysmal wall revealed intimal hyperplasia without atherosclerotic change.

BACKGROUND: It is often difficult to make a diagnosis of cardiac ischemia in patients attending emergency department (ED) with symptoms of acute coronary syndromes (ACS) because existing cardiac markers are not sensitive for reversible myocardial ischemia. Ischemia modified albumin (IMA) has recently been shown to be an early and sensitive marker of myocardial ischemia. We investigated the usefulness of ischemia modified albumin (IMA) as an early triage marker for ACS and tried to establish a newly standardized albumin-adjusted IMA index which has been expected to be more sensitive and accurate than conventional IMA value. METHODS: We enrolled 209 consecutive patients (men 95, women 114) who presented to the ED with symptoms suggestive of ACS from June to July, 2005. All patients were classified to ACS group (n=42) and others (n=167) based on diagnosis of cardiologists. The ideal cutoff value of IMA was calculated by the receiver operating characteristic (ROC) curve analysis and diagnostic utilities of combination tests (myoglobin, CK-MB, troponin T and EKG) were compared with those of IMA. The albumin-adjusted IMA index was calculated and applicated from the results of correlation assay between serum albumin concentration and IMA value. RESULTS: Mean IMA level (U/mL) of ACS group was significantly higher than that of non-ACS group (P<0.05) and sensitivity and specificity was 92.9% and 35.9% at a cutoff value of 85.1 U/mL, respectably. In combination with conventional cardiac markers, the sensitivity increased to 96.3%. IMA value had a negative lnear relationship with serum albumin concentration (YIMA= -23.1Xalbumin+200, R=0.99) and albumin-adjusted IMA index was calculated as [IMA index = serum albumin conc. (g/dL) x 23 + IMA (U/mL) -100]. The sensitivity and specificity was 97.6% and 34.1% at a cutoff value of 83.3 IMA index, respectively. CONCLUSIONS: IMA is a useful sensitive marker for the identification of ACS in patients with normal cardiac markers and EKG finding and follow-up combination testing may be required to rule out other diseases. The calculated albumin-adjusted IMA index is recommended to make a diagnosis of ACS more sensitively.
