We assessed association between novel biomarkers of cardiovascular disease and conven tional factors in 40 years old subjects (208 men and 266 women) from the general population of Slovakia. FER HDL (cholesterol esterifi cation rate in HDL plasma), AIP - Atherogenic Index of Plasma [Log(TG/HDL-C)] as markers of lipoprotein particle size, and CILP2, FTO and MLXIPL polymorphisms, were examined in relation to biomarkers and conventional risk factors. Un ivariate analyses confirmed correlation between AIP, FERHDL and the most of measured parameters. Relations between AIP and CILP2, FTO and MLXIPL were not significant. However, CILP2 was significantly related to FERHDL in both genders. In multivariate analysis BMI was the strongest correlate of AIP levels. In multivariate model variability of FER HDL was best explained by AIP (R2 =0.55) in both genders with still significant effect of CILP2 SNP in men. In a model where AIP was omitted, TG leve ls explained 43 % of the FER HDL variability in men, while in women HDL-C was the major determinant (42 %). In conclusions, FERHDL and AIP related to the known markers of cardiovascular risk provide means to express their subtle interactions by one number. Our novel finding of association between CILP2 polymorphism and FERHDL supports its role in lipid metabolism., K. Rašlová ... [et al.]., and Obsahuje bibliografii a bibliografické odkazy

Práce se zabývá interferencí dobutaminu s metodami využívajícími princip Trinderovy reakce a podmínkami získání vzorku u pacientů v intenzivní péči. Dobutamin výrazně snižuje koncentrace některých analytů (kreatinin stanovený enzymově, kyselina močová, triacylglyceroly, cholesterol, lipáza). Interference se projeví pouze při hrubém porušení zásad pro odběr vzorků., The main goal of the study is to examine analytical interference caused by dobutamine influencing methods based on Trinder peroxidase reaction and possible preanalytical pitfalls in Intensive Care Units. Dobutamine interference has significant impact on some laboratory tests, causing falsely low values upon determination of: Creatinine - enzymatic method, Uric acid, Triglycerides, Cholesterol and Lipase. The phenomenon occurs predominantly as a result of violating specimen collection rules., Sečník P. Jr., Franeková J., Komínková M., Kotrbatý J., Hunal Z., Tlučhořová D., Jabor A., and Literatura 5
Many functions of the cardiovascular apparatus are affected by gender. The aim of our study was find out whether markers of cell death present in the donor myocardium differ in male and female hearts. The study involved 81 patients undergoing heart transplantation from September 2010 to January 2013. Patients were divided into two groups: male allograft (n=49), and female allograft (n=32). Two types of myocardial cell death were analyzed. High-sensitive cardiac troponin T as a necrosis marker and protein bcl-2, caspase 3 and TUNEL as apoptosis markers were measured. We observed a significantly higher level of high-sensitive cardiac troponin T after correcting for predicted ventricular mass in female donors before transplantation as well as in the female allograft group after transplantation throughout the monitored period (P=0.011). There were no differences in apoptosis markers (bcl-2, caspase 3, TUNEL) between male and female hearts before transplantation. Both genders showed a significant increase of TUNEL-positive myocytes one week after transplantation without differences between the groups. Moreover, there were no differences in caspase 3 and bcl-2
expression between the two groups. Our results demonstrated the presence of necrotic and apoptotic cell death in human heart allografts. High-sensitive cardiac troponin T adjusted for predicted ventricular mass as a marker of myocardial necrosis was higher in female donors, and this gender difference was even more pronounced after transplantation.
