Purpose: Developing a curriculum(DACUM) is a method of analyzing job focused competency, which is obtained from the data of an expert belonging to a certain career. In this study the DACUM method was used to analyze the jobs of operating room nurses. Method: Through the DACUM workshop which was arranged by two DACUM facillitators, a definition of the role of operating room nurses was developed and then duties and tasks of operating room nurses' were identified. For the workshop, a DACUM committee with 10 operating room nurses was organized. Finally, the duties and tasks which were identified were validated by 422 nurses for importance, difficulty, and frequency. Results: Thirteen duties and 105 tasks were identified on the DACUM chart, where importance, difficulty, and frequency of tasks were represented by alphabet letters A, B, and C as higher degree of importance. The determinant coefficient(DC) showed that the most important duty was assisting with operations(DC=6.61), and the least, managing operating materials(DC=4.22). For tasks, the most important ones were assisting in orthostatic surgery(DC=7.60), and assisting in thoracic surgery(DC=7.38), and the least important making gauze ball(DC=2.39), and saving of operation site((DC=3.27). Conclusion: The results suggest a need to develop an education program using the DACUM chart as a basis for the development and as a clinical career ladder and for curriculum of operating room nursing.

BACKGROUND: The annual incidence of venous thromboembolism (VTE) is increasing, and the treatment pattern of oral anticoagulants (OACs) has changed with introduction of new oral anticoagulants (NOACs). The aims of this study were to assess the annual incidence of VTE in a Korean population and the change of treatment pattern with availability of NOACs using a population-based database. METHODS: Using the Korean National Health Insurance Services database, we identified patients diagnosed with VTE between 2009 and 2016. The annual prevalence of VTE and clinical characteristics and treatment pattern were investigated. The annual incidence of VTE was calculated using direct and indirect methods using the estimated Korean population in 2009 as the reference. RESULTS: The annual incidence of VTE in Korean has increased yearly from 23.9 per 100,000 in 2009 to 42.2 in 2016. The overall rate of OAC prescription for VTE treatment increased from 55.9% to 68% in the same time period. The rate of initiation of NOAC treatment greatly increased, particularly from 2013 onwards, with a 20-fold increase from 2009 to 2016 (2.1% vs. 54.3%). CONCLUSIONS: The annual incidence of VTE in Korea increased by almost two-fold from 2009 to 2016. The rate of initiation of NOAC treatment has increased substantially since 2013, and these agents have surpassed VKAs as the anticoagulant of choice for VTE. This temporal pattern of OAC prescription is consistent with the current clinical guidelines, which indicate NOACs over the warfarin in patients with VTE.

<P>Abstract: Background: </P><P>The anaphylatoxin C5a is a potent inflammatory molecule generated during complement activation. Although some reports have implicated C5a in xenograft rejection, to date, the molecular compatibility between human C5a and porcine C5a receptor (C5aR) has been little studied. To examine the need for pC5aR-deficient pig in xenotransplantaion, we aimed to look at the degree of direct interaction between human C5a (recipient side) and porcine endothelial cells (PECs) and porcine polymorphonuclear neutrophils (PMNs) (donor side).</P><P>Methods: </P><P>Following the treatment of human C5a to isolated porcine PMNs, transmigration of PMNs was measured by Transwell system and superoxide generation by cytochrome <I>c</I> reduction assay. Next, the effects of human C5a on several intracellular signaling pathways were further checked; actin cytoskeletal change was observed under a confocal microscope after staining with Alexa Fluor-546-phalloidin, intracellular calcium mobilization was measured by spectrofluorophotometer. The degree of direct effect of human C5a on porcine PMNs was compared with that in human PMNs. Finally, microarray was performed to monitor the effect of human C5a on gene expression of PEC and the expression of several candidate proteins was checked by flow cytometry.</P><P>Results: </P><P>We found that human C5a was able to induce chemotaxis, superoxide generation, actin cytoskeletal change, and intracellular calcium mobilization in porcine PMNs. However, higher concentration of human C5a was required to stimulate porcine PMNs in comparison with activating human PMNs. The amino acid sequences of porcine C5aR with those of human C5aR showed a sequence homology of only 67%. To elucidate the effect of human C5a to PECs, microarray analysis following the treatment of PECs with human C5a was performed. These data showed that human C5a did not significantly affect gene transcription patterns in PECs. Additionally, treatment of PECs with human C5a also did not induce protein expression of several cell adhesion molecules, including vascular cell adhesion molecule-1, intercellular adhesion molecule-1, P-selectin, and E-selectin, or secretion of interleukin-8 from PECs.</P><P>Conclusions: </P><P>These results suggest that human C5a may play a minor role on PEC activation possibly due to molecular incompatibility across the species barrier.</P>

An elastase inhibitor, SMFEI02, was isolated from culture broth of Streptomyces lavendulae SMF11. The inhibitor was purified by ultrafiltration followed by XAD-7 column and Dowex-1 anion-exchange chromatographies, and preparative HPLC. The molecular formula was determined to be C_14H_16N_2O_2 (MW 244) by HRFAB-MS analysis. The inhibitor was identified to be a diketopiperazine cyclo(S-Phe-S-Pro) by the optical rotation value and NMR spectral data, and showed inhibitory activities for trypsin, chymotrypsin, cathepsin B, and papain as well as elastase with the K_i values ranging from 1.78mM to 2.86μM. The inhibition showed a competitive mode for elastase, chymotrypsin, and cathepsin B, whereas it showed a noncompetitive mode for trypsin and papain.

We investigated the antioxidant and cholinesterase inhibitory activities of the aqueous extract of rainbow trout Oncorhynchus mykiss. The antioxidant activity of O. mykiss aqueous extract was determined by in vitro peroxynitrite scavenging activity and reducing power assays. The aqueous extract of O. mykiss showed potent peroxynitrite radical scavenging activity ($IC_{50}=0.12{\pm}0.001\;mg/mL$) and reducing power (absorbance=$0.47{\pm}0.001$) at the concentration of 1 mg/mL. The in vitro cholinesterase inhibitory activity of O. mykiss aqueous extract was examined using spectrophotometric analyses of acetyl- and butyrylcholinesterase. The aqueous extract of O. mykiss showed acetylcholinesterase inhibitory activity ($IC_{50}=1.61{\pm}0.13\;mg/mL$), but did not exhibit inhibitory activity against butyrylcholinesterase. These results suggest that O. mykiss possesses antioxidant and acetylcholinesterase inhibitory activities and provide scientific evidence for the health benefits of O. mykiss aqueous extract.

Actinomycosis is a chronic suppurative and granulomatous disease. Actinomyces is a gram positive, anaerobic and non-acid fast bacterium. Many actinomycotic pelvic infection in women used intrauterine device(IUD) with long duration were reported, in contrast, others suggest that actinomycosis develop opportunistic infection irrespective of intrauterine device. One to ten percents of patients with acute pelvic inflammatory disease(PID) develop perihepatic inflammation and adhesion--the Fitz-Hugh-Curtis syndrome. Although in the past Neisseria gonorrhea was thought to be the only etiological agent, recent data indicate that chlamydia trachomatis produces the majority of cases. We have experienced the case of tubo-ovarian actinomycosis(case with IUD(Cu-T)) associated with Fitz-Hugh-Curtis syndrome in a 29years old woman, and reported that with a review of related literatures.
