Purpose The aim of this study was to investigate the effectiveness of an educational intervention on home nursing care plans based on NANDA, Nursing Interventions Classification, and Nursing Outcomes Classification for registered nurses working at primary healthcare settings in Greece. Methods This is a quasi-experimental study without a control group. The sample consisted of 19 registered nurses. The study tool was a questionnaire administered pre- and post-educational intervention. Findings The intervention improved their skills on nursing diagnoses' nomination, proper formulation, and individualization of defining characteristics, but it did not improve them in desired outcomes formulation. Conclusions A significant effect of an educational intervention on nursing care plans was demonstrated. Implications for Nursing Practice Nurses' knowledge and attitudes are important for understanding and integrating documentation within the nursing process. [ABSTRACT FROM AUTHOR]

Burley tobaccos ( Nicotiana tabacum) display a nitrogen-use-deficiency phenotype that is associated with the accumulation of high levels of nitrate within the leaf, a trait correlated with production of a class of compounds referred to as tobacco-specific nitrosamines ( TSNAs). Two TSNA species, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone ( NNK) and N-nitrosonornicotine ( NNN), have been shown to be strong carcinogens in numerous animal studies. We investigated the potential of molecular genetic strategies to lower nitrate levels in burley tobaccos by overexpressing genes encoding key enzymes of the nitrogen-assimilation pathway. Of the various constructs tested, only the expression of a constitutively active nitrate reductase ( NR) dramatically decreased free nitrate levels in the leaves. Field-grown tobacco plants expressing this NR variant exhibited greatly reduced levels of TSNAs in both cured leaves and mainstream smoke of cigarettes made from these materials. Decreasing leaf nitrate levels via expression of a constitutively active NR enzyme represents an exceptionally promising means for reducing the production of NNN and NNK, two of the most well-documented animal carcinogens found in tobacco products.
