The effect of theoretical and simulation training on medical errors of nurse students in karadeniz technical university, Turkey

Objective: To assess the efficacy of theoretical training related to medical errors and patient safety and practical simulation training on students' knowledge and skill levels. Methods: This experimental study was conducted from March 28 to May 18, 2016, at nursing department of a university and comprised of students attending the third grade of the nursing school. The subjects were divided into two equal experimental and control groups. The experimental group, among other things, received simulation training that involved a demonstration and subsequent one-to-one practice. Data was collected on a proforma that included demographic information, pretest and post-test scores, checklists for pre-assessments and final assessments related to nursing practices. Results: There were 62 nurses divided into two groups of 31(50%) each. The difference between post-test scores of the concerning theoretical training about medical errors and patient safety was statistically significant (p0.05), while there was a significant difference between their final assessments (p<0.05). Conclusion: Theoretical education increased students' levels of knowledge regarding medical errors and patient safety, and the the practical simulation training reduced malpractices by improving skills. © 2018, Pakistan Medical Association.

Chemical constituents and antimicrobial activity of the essential oil from vicia dadianorum extracted by hydro and microwave distillations

The aim of this research was to investigate the influence of extraction methods on yield and chemical composition of the essential oil of Vicia dadianorum Somm. & Lev. The volatiles of V. dadianorum have been isolated by hydro and microwave distillations (HD and MD). The compositions of the essential oils were characterized by GC-FID and GC-MS. A total of seventy-six and fifty-six compounds were identified, constituting over 90.9%, and 80.1% of oil composition of V. dadianorum, respectively. Sesquiterpene hydrocarbons were shown to be the main group of volatiles (HD: 26.2% and MD: 15.9%). The major terpene constituent of the essential oils of V. dadianorum was ?-elemene (HD, 13.7% and MD, 8.4%). Comparative study showed that the amount of total volatiles (90.9%) and the major constituent (26.2%) were found to be better in HD of V. dadianorum. The antimicrobial activity of the isolated essential oils of the plant was also investigated, and it showed moderate antimicrobial and antifungal activities against Staphylococcus aureus, Enterococcus faecalis, Bacillus cereus, Mycobacterium smegmatis and Candida albicans

Chemical composition and antimicrobial activity of the essential oils from the flower, leaf, and stem of Senecio pandurifolius

The essential oils from the fresh flower, leaf, and stem of Senecio pandurifolius (Asteraceae) were isolated by hydrodistillation in a Clevenger-type apparatus, and characterized by GC-FID and GC-MS. A total of forty-five, sixty, and forty-two compounds were identified, constituting over 90.1%, 88.0%, and 89.0% of oil composition of the flower, leaf, and stem of S. pandurifolius, respectively. The chemical profile reveals the dominance of sesquiterpene hydrocarbons (flower: 42.4%, leaf: 43.4%, stem: 52.3%). The main components of essential oils own to S. pandurifolius were ?-cuprenene (30.7%) in flower, ?-zingiberene (16.1%) in leaf and ?- curcumene (14.9%) in stem. Terpene related compounds were in minor amounts in all parts (flower: 1.4%, leaf: 1.5%, stem: 1.9%) of the S. pandurifolius. Also there was no monoterpene hydrocarbons and oxygenated monoterpenes in the essential oil of the stem. In addition, antimicrobial activities of the essential oils of S. pandurifolius were investigated. The oils showed activity against Gram positive bacteria, mycobacterium and fungi, but not Gram negative bacteria. A high antimycobacterial activity was observed with leaf essential oil, which deserves further investigation to determine its active components. © 2011 Reproduction is free for scientific studies

Antimicrobial activity and a comparative essential oil analysis of Centaurea pulcherrima Willd. var. pulcherrima extracted by hydrodistillation and microwave distillation

PubMed: 21902569The essential oils of Centaurea pulcherrima Willd. var. pulcherrima (Asteraceae) were isolated by hydrodistillation (HD) and a microwave distillation (MD), than characterised by GC-FID and GC-MS. A total of 58 and 57 compounds were identified, constituting over 93.7%, and 91.6% of volatile oil composition of C. pulcherrima var. pulcherrima, respectively. Sesquiterpene hydrocarbons were shown to be the main group of constituents (HD: 42.4% versus MD: 51.5%). The major component of the oils of C. pulcherrima var. pulcherrima was germacrene D (HD, 17.8% versus MD, 23.2%). The antimicrobial activity of the isolated essential oils of the plant was also investigated, and they showed good antibacterial activity against to tested Gram-positive bacteria, especially to M. smegmatis and a yeast-like fungus C. albicans. © 2011 Taylor & Francis.This work was supported by grants from Karadeniz Technical University Research Fund and State Planning Agency (DPT) of Turkey.

Composition and antimicrobial activity of the essential oils from flowers of Senecio othonnae, S. racemosus, and S. nemorensis

PubMed: 20521557The chemical composition of the essential oils of Senecio othonnae, S. racemosus, and S. nemorensis obtained by hydrodistillation of fresh flowers were analysed by GC-FID and GC-MS. A total of seventy-six compounds were identified, constituting over 83.1%, 97.7% and 86.8% of the total oil composition of the flowers of S. othonnae, S. racemosus, and S. nemorensis. The main components of the oils were caryophyllene oxide (18.6%), (E)-?-farnesene (21.6%), and ?-curcumene (42.8%), respectively. Sesquiterpene hydrocarbons were the main group of constituents of all three species, forming 34.6%, 73.2%, and 81.8% of the oils, respectively. The oils of S. othonnae, and S. nemorensis showed antimicrobial activity against Bacillus cereus, Staphylococcus aureus, Enterococcus faecalis, and Candida tropicalis, but that of S. racemosus was only active against Candida tropicalis

However, the major group in the leaf oil was found to be oxygenated monoterpenes (43.5%). Salicylaldehyde (20.7% and 79.5%) was the major component of the flower and stem oils of P. daurica, respectively. Linalool (31.4%) was the main compound of the leaf oil. The antimicrobial activity of the isolated essential oils of the plant was also investigated, and they showed moderate antibacterial activity against tested microorganisms. © 2011 Tübïtak
