BACKGROUND C-reactive protein concentration has continuous associations with risk of coronary artery disease, ischemic stroke and death from several cancers. In addition, several studies have shown that CRP could be used to predict first ever myocardial infarction and stroke in healthy subjects, as well as outcome in acute setting. High levels of another biomarker, D-dimer, have been found to b...

Degree assortativity is the tendency for nodes of high degree (resp. low degree) in a graph to be connected to high degree nodes (resp. to low degree ones). It is usually quantified by the Pearson correlation coefficient of the degree–degree correlation. Here we extend this concept to account for the effect of second neighbours to a given node in a graph. That is, we consider the two-walks degr...

BACKGROUND Musculoskeletal disorders (MSDs) are a serious problem among the nursing staff. Mental workload is the major cause of MSDs among nursing staff. The aim of this study was to investigate the mental workload dimensions and their association with MSDs among nurses of Alzahra Hospital, affiliated to Isfahan University of Medical Sciences. MATERIALS AND METHODS This descriptive cross-sec...

The main objectives of this article are the assessment of agreement between measure-based and report-based information on weight and height, besides the identification of the main characteristics related to 150 pregnant women who could report (versus could not report) their pre-gestational weight, weight at delivery, and height. According to the results, report-based information on previous wei...

We studied the between-therapist reliability and the validity of four instruments in measuring lumbar spine curvature and pelvic tilt. The four instruments and their measurements were 1) a tape measure to measure the change in lumbar curvature during trunk flexion; 2) a gravity goniometer to measure pelvic angle and lumbar curvature during stance, trunk flexion, and trunk extension; 3) a parall...

CONTEXT Recommendations for management of jaundice in newborns presume thatjaundice is a reliable clinical finding and that the pattern and intensity of jaundice reflects the degree of elevation of the serum bilirubin level. OBJECTIVES To determine whether experienced observers agree in describing the extent of jaundice and to evaluate the reliability of visual assessment as an indication for...

BACKGROUND We hypothesized that induction of general anesthesia using sevoflurane improves the accuracy of non-invasive hemoglobin (SpHb) measurement of Masimo Radical-7® Pulse CO-Oximetry by inducing peripheral vasodilation and increasing the perfusion index (PI). The aim of this study is to investigate the change in the SpHb and the PI measured by Rad7 during induction of general anesthesia u...

Methods of testing the equality of conditional correlation of bivariate data across a third variable of interest (covariate) have been studied [9, 10, 11, 12, 13, 14, 15, 16]. Most of these methods, such as the test based on Fisher z-transformation [15], the likelihood ratio tests, and the C(α) statistics [9], are limited to the case where a categorical covariate is considered. When the covaria...

PURPOSE To evaluate short-term repeatability, intereye correlation, and effect of ocular dominance on macular pigment optical density (MPOD) measurements obtained using the QuantifEye Heterochromatic Flicker Photometer. PATIENTS AND METHODS A total of 72 study participants were enrolled in this prospective, cross-sectional study. Participants underwent a comprehensive ocular evaluation, inclu...

The aim of this study was to screen for key biomarkers of osteosarcoma (OS) by tracking altered modules. Protein-protein interaction (PPI) networks of OS and normal groups were constructed and re-weighted using the Pearson correlation coefficient (PCC), respectively. The condition-specific modules were explored from OS and normal PPI networks using a clique-merging algorithm. Altered modules we...
