84. According to the principal factor analysis of the tetrachoric correlation matrix, the three factors with the highest Eigenvalues were associated with (i) Relatively easy clinical observations, (ii) the signs which require a longer observation time and detailed anamnesis, and (iii) the signs, which require detailed examination and observation. The factors explained cumulatively 65.98% of the total variance. CONCLUSION The findings obtained in this study showed that the adapted questionnaire addressed in the scope of this study is a valid measure for Turkish society.

In this study, we aimed to investigate FFR predictors after propensity score matching (PSM) analysis in patients with intermediate coronary lesions. METHODS Patients who underwent coronary angiography between January 2014 and March 2015 due to suspicion of coronary artery disease were included in this study. Patients were divided into two groups according to the FFR status and predictors of FFR before and after PSM analysis were investigated. RESULTS A total of 290 patients (a total of 310 lesions) were included in this study (61±12 years, 75.5% male). In univariate analysis, after PSM analysis, Diameter stenosis (DS) and proximal LAD lesion (PLL) were associated with lower FFR values. CONCLUSION This study indicated that the majority of traditional FFR predictors did not reach the limit of significance after PSM analysis and we suggest that DS and PLL are one step ahead of predicting lesion severity compared to other traditional risk factors.

METHODS Three groups of adult male Wistar rats under anesthesia were implanted with bilateral cortical recording electrodes for the GBL group (GBL) and/or bipolar stimulation electrodes into the right basolateral amygdala for the Kindling group (KI) alone and Kindling plus GBL group (GBL+KI). Rats in the KI and GBL+KI groups were stimulated twice daily at the afterdischarge threshold until they reached Racine's stage 5 seizure state. The animals in the GBL + group had an i.p injection of GBL 20 minutes before each electrical stimulation, and the effects of GBL-induced seizures on the development of kindling were investigated. The animals in the GBL group were injected GBL twice daily i.p. for 15 days without receiving any electrical stimulation. RESULTS The KI animals reached stage 5 seizure stage at 12th stimulations, whereas the GBL+KI rats reached at 27th stimulations. The mean numbers of stimulations needed for the development of the first stage 3, 4, or 5 generalized seizures were significantly higher in the GBL+KI group than the KI group. CONCLUSION The resistance to amygdala kindling in the GBL model can be modulated by the absence seizure mechanism alone, without the intervention of an abnormal genetic background.

METHODS Sixty patients were included in this study. Echocardiography and 24-hours Holter monitoring were performed after measurement of serum NT-pro BNP concentration. The patients were classified into two groups concerning the occurrence of PAF on Holter recordings. Biochemical and echocardiographic parameters of patients with and without PAF were compared. SCH-442416 RESULTS PAF was detected in 28 (46%) patients. Patients with PAF demonstrated higher NT-pro BNP levels, mitral and aortic regurgitation velocities, E/A, E/E', pulmonary capillary wedge pressure, pulmonary artery systolic pressure, left atrial volume and volume indices. NT-pro BNP was established as the predictor of PAF (OR=1.23, 95% CI 1.08-1.42; p=0.001). ROC analysis showed an NT-pro BNP value of 2188 pg/mL as cut-off value with 68% sensitivity and 84% specificity [Area under the ROC curve (AUC)=0.826, CI 95% 0.724-0.927; p less then 0.001]. CONCLUSION The triggering factors for AF are increased intracardiac pressures, left atrial dilatation and increased wall tension. As an indicator of increased wall tension, elevated levels of NT-pro BNP predict the development of PAF.

In this study, we aimed to compare the oblique approach with the classical short-axis technique for facilitating the procedure and reduction of mechanical complications. METHODS This research was planned as a prospective study. Eighty-four open-heart surgery patients requiring a central venous catheter were randomly allocated into two groups Oblique approach group (n=42) and short-axis group (n=42). Time to cannulate, the number of necessary puncture attempts, and frequency of carotid artery puncture, hematoma, puncture site bleeding, pneumothorax, and hemothorax in each group were recorded. Visualization of the vein and the needle using ultrasound were also evaluated by a subjective scale. RESULTS The patient's characteristics were comparable between the two groups. The mean time of catheterization was 52.00±70.18 seconds in the oblique approach group and 40.76±49.30 seconds in short-axis group. The mean number of needle puncture attempts was 1.21±0.61 in oblique approach and 1.12±0.50 in short-axis group. The results did not differ significantly. There was an improved visualization of the needle in the oblique approach group, but this was not proved as statistically significant. CONCLUSION The results of our study suggest that the lateral oblique approach is a safe and effective technique, which can be a strong alternative to the classical short-axis technique for ultrasound-guided catheterization of the internal jugular vein.
