Cíl: Cílem práce bylo validizovat diagnostické prvky ošetřovatelské diagnózy Úzkost 00146 vybraným souborem porodních asistentek-expertek a zjistit, které diagnostické prvky porodní asistentky považují za hlavní, a které za vedlejší. Metody a soubor: Pro obsahovou validizaci byl využit Fehringův model validity diagnostického obsahu (Diagnostic Content Validity Model). Soubor tvořilo 34 porodních asistentek-expertek. Za expertky byly považovány porodní asistentky, které získaly minimálně 4 body podle modifi kovaných Fehringových kritérií. Porodní asistentky-expertky splňovaly kritérium bakalářského stupně vzdělání v oboru porodní asistence nebo s minimální délkou praxe na porodním sále 5 let. Pro posouzení významnosti diagnostických prvků byl použit měřící nástroj (záznamový arch) obsahující 79 položek – diagnostických prvků uvedených v klasifi kačním systému NANDA-International. Výsledky: Za hlavní určující znaky (vážené skóre vyšší než 0,75) považovaly porodní asistentky-expertky vnitřní nepokoj (vážené skóre 0,76), zvýšení tlaku krve (0,75), tachykardie (0,75), tachypnoe (0,75) a hlavní související faktor ohrožení v postavení role ve zdravotním stavu (0,76). Závěr: Z výsledků výzkumu vyplývá, že porodní asistentky-expertky považují (z celkového nabízeného počtu 79 diagnostických prvků) pro celkové posouzení stavu klientky-rodičky přicházející na porodní sál k porodu pouze 5 z nich za hlavní., Aim: The aim of the work was to validate diagnostic elements of the nursing diagnosis Anxiety 00146 by a selected sample of experts-midwives in the Czech Republic, and see which diagnostic elements they consider major and minor. Methods: The study followed Fehring Diagnostic Content Validity Model. A set of experts included 34 midwives from the Czech Republic who received at least 4 points according to the modified Fehring criteria. Experts had bachelor’s degree in midwifery or minimal fi ve years of clinical practice. For accessing the significance of diagnostic elements we built a measurement instrument containing 79 items – the diagnostic elements listed in the classification system of NANDA-International. Results: Out of the 79 defining characteristics considered by experts-midwives five characteristics were described as major (score ≥ 0,75): internal restlessness (0,76), increased blood pressure (0,75), tachycardia (0,75), tachypnea (0,75), threats to the status of role in health (0,76). Conclusion: The results of this study indicate that midwives consider only five defining characteristics as major for assesing anxiety of mothers coming to the delivery room for delivery., Štěpánka Bubeníková, Věra Vránová, and Literatura
Mediator is a multiprotein complex that connects regulation mediated by transcription factors with RNA polymerase II transcriptional machinery and integrates signals from the cell regulatory cascades with gene expression. One of the Mediator subunits, Mediator complex subunit 28 (MED28), has a dual nuclear and cytoplasmic localization and function. In the nucleus, MED28 functions as part of Mediator and in the cytoplasm, it interacts with cytoskeletal proteins and is part of the regulatory
cascades including that of Grb2. MED28 thus has the potential to bring cytoplasmic regulatory interactions towards the centre of gene expression regulation. In this study, we identified MDT-28, the nematode orthologue of MED28, as a likely target of lysine acetylation using bioinformatic prediction of post-translational modifications. Lysine acetylation was experimentally confirmed using anti-acetyl lysine antibody on immunoprecipitated GFP::MDT-28 ex-pressed in synchronized C. elegans. Valproic acid (VPA), a known inhibitor of lysine deacetylases, enhanced the lysine acetylation of GFP::MDT-28. At the subcellular level, VPA decreased the nuclear localization of GFP::MDT-28 detected by fluorescence-lifetime imaging microscopy (FLIM). This indicates that the nuclear pool of MDT-28 is regulated by a mechanism sensitive to VPA and provides an indirect support for a variable relative proportion of MED28 orthologues with other Mediator subunits. and Corresponding author: Markéta Kostrouchová
This study investigated the value of oxygen (O2) pulse curves obtained during cardiopulmonary exercise testing (CPET) for the diagnosis of coronary artery disease (CAD). Forty patients with known coronary anatomy (35.0 % normal, 27.0 % single-vessel and 38.0 % multivessel CAD) underwent CPET with radiotracer injection at peak exercise, followed by myocardial scintigraphy. O2 pulse curves were classified as: A-normal, B-probably normal (normal slope with low peak value); C-probably abnormal (flat, with low peak value); or D- definitely abnormal (descending slope). Sensitivity, specificity, positive and negative predictive values of the O2 pulse curve pattern (A or B vs. C or D) for the diagnosis of CAD were, respectively, 38.5 %, 81.3 %, 76.9 %, and 44.8 %. The concordance rate between the abnormal O2 pulse curve pattern and ischemia in myocardial scintigraphy was 38.1 %. Age and the extent of scintigraphic perfusion defect, but not the abnormal O2 pulse curve patterns (B or C or both combined) were independently associated with CAD. In conclusion, the O2 pulse curve pattern has low diagnostic performance for the diagnosis of obstructive CAD, and the abnormal curve pattern was not associated with myocardial ischemia defined by scintigraphy., A.
