Results RV function measured by CMR was negatively correlated with peak systolic strain of mid RV free wall (P=0.038, Pearson r=-0.357) and also negatively correlated to both mean of strain (P=0.028, Pearson r=-0.376) and SR (P=0.035, Spearman’s rho=-0.362) of basal , mid and apical segments of RV. Conclusions Overall, in the assessment of RV function , echocardiographic measurement of strain a...

OBJECTIVES To determine the ability of students' preadmission academic variables to predict osteopathic medical school performance and whether students' sex, undergraduate major, or undergra...
BACKGROUND AND OBJECTIVES The Faces Pain Scale-Revised (FPS-R) and Color Analog Scale (CAS) are self-report pain scales commonly used in children but insufficiently validated in the emergency department setting. Our objectives were to determine the psychometric properties (convergent validity, discriminative validity, responsivity, and reliability) of the FPS-R and CAS, and to determine whether...
BACKGROUND Careful observation of the longitudinal course of bipolar disorders is pivotal to finding optimal treatments and improving outcome. A useful tool is the daily prospective Life-Chart Method, developed by the National Institute of Mental Health. However, it remains unclear whether the patient version is as valid as the clinician version. METHODS We compared the patient-rated version ...
BACKGROUND Structural remodeling is associated with the fibroinflammatory process in the atrial extracellular matrix. In the present study we aimed to investigate whether serum levels of new circulating remodeling markers differ in patients with atrial fibrillation (AF) compared to patients with sinus rhythm. MATERIAL AND METHODS The study population included 52 patients diagnosed with non-va...
