OBJECTIVE US is a promising tool in evaluating RA synovitis, but abnormal US findings have been reported in small subsets of normal joints in healthy subjects. This study aimed to systematically assess greyscale US (GSUS) and power Doppler US (PDUS) findings in 40 peripheral joints-the 28-joint DAS (DAS28) set, ankles and MTP joints-in healthy subjects. A composite score of abnormal US findings...

INTRODUCTION Hair shedding is a common consequence of the normal hair cycle that changes with internal and external factors. Female pattern hair loss (FPHL) is difficult to assess in terms of shedding severity as the conscious perception of hair shedding varies according to each individual, and most utilized methods are semi-invasive or very time consuming. In this study, we establish and valid...

Herein, we propose a Spearman rank correlation-based screening procedure for ultrahigh-dimensional data with censored response cases. The proposed method is model-free without specifying any regression forms of predictors or variables and robust under the unknown monotone transformations these variable predictors. sure-screening rank-consistency properties are established some mild regularity c...

BACKGROUND Fibroblast growth factor-23 (FGF-23), a novel marker of bone disease in chronic kidney disease (CKD) has been shown to correlate with vascular calcifications. We aimed to describe the effect of the calcium phosphate product (Ca*P) on FGF-23 concentrations in children and young adults without confounding cardiovascular disease. METHODS Pediatric and young adult patients with CKD sta...

BACKGROUND Rapid growth in global health activity among US medical specialty education programs has lead to heterogeneity in types of activities and global health training models. The breadth and scope of this activity is not well chronicled. METHODS Using a standardized search protocol, we examined the characteristics of US medical residency global health programs by number of programs, clin...

In this article we describe a new Hermite series based sequential estimator for the Spearman rank correlation coefficient and provide algorithms applicable in both stationary non-stationary settings. To treat setting, introduce novel, exponentially weighted correlation, which allows local nonparametric of bivariate data stream to be tracked. best our knowledge is first algorithm proposed estima...
