Background: Venous thromboembolism is an entity that encompasses both deep vein thrombosis and pulmonary thromboembolism. Although protocols for the diagnosis of these diseases are well defined, there is evidence of inappropriate use of diagnostic resources.

Objectives: To define the epidemiological profiles of patients admitted to the emergency department with suspected deep vein thrombosis, to determine rates of inappropriate ordering of D-dimer assays and color venous Doppler echocardiography of the lower limbs, and to identify whether these requests followed the recommendations contained in the 2015 Brazilian Society of Angiology and Vascular Surgery guidelines.

We studied whether children with severe developmental disabilities (SDDs) who have a comorbid behavioral disorder also have higher rates of special healthcare needs (SHCNs). We used a matched-comparison control group design to establish whether SHCNs were higher in children with SDDs with behavioral disorders versus children with SDDs without behavioral disorders. Thirty-six children were matched for age (mean 12 y 6 mo; range 5 y 2 mo-18 y 8 mo), sex (24 males, 12 females), ethnicity (22 non-white), mental retardation level (22 moderate, eight severe, six profound), and Diagnostic and Statistical Manual of Mental Disorders, 4th edition axis I diagnosis (18 autism spectrum disorder, 10 specified syndrome, eight mental retardation not otherwise specified).

Background: In light of widespread undertreatment for glucocorticoid-induced osteoporosis (GIOP), we designed a group randomized controlled trial to increase bone mineral density (BMD) testing and osteoporosis medication prescribing among patients receiving long-term glucocorticoid therapy.

Methods: Using administrative databases of a large US health plan, we identified physicians who prescribed long-term glucocorticoid therapy to at least 3 patients. One hundred fifty-three participating physicians were randomized to receive a 3-module Web-based GIOP intervention or control course.

In the central nervous system of Drosophila, the induction of the glial cell fate is dependent on the transcription factor glial cells missing (gcm). Though a considerable number of other genes have been shown to be expressed in all or in subsets of glial cells, the course of glial cell differentiation and subtype specification is only poorly understood. This prompted us to design a whole genome microarray approach comparing gcm gain-of-function and, for the first time, gcm loss-of-function genetics to wildtype in time course experiments along embryogenesis.

Purpose: Following its licensure, tuberculosis (TB) was reported as a potential adverse effect of infliximab. Subsequently, the product circular was changed to recommend tuberculin skin testing before patients received infliximab, which was reinforced by several risk communication efforts. The aim of this study was to evaluate patterns and predictors of documented tuberculin skin testing in patients before and after manufacturer, federal, and academic risk communications.

Objective: To evaluate patient and physician factors associated with prevention of glucocorticoid-induced osteoporosis and to describe temporal trends in screening and prevention of glucocorticoid-induced osteoporosis.

Methods: Using databases from a national managed care organization, enrollees who had been prescribed glucocorticoids (taken for at least 60 days) during an 18-month period were identified. Administrative data from January 2001 through June 2003 and linked survey data from October 2003 were examined for measurement of bone mass, prescription of antiresorptive medication, and use of over-the-counter calcium and/or vitamin D treatment.

Endothelial cell layers from umbilical cords were grown on methylated silica surfaces. Fluorescence microscopy showed this layer to be confluent and to consist of living cells. Initial ellipsometry measurements were performed to illustrate both the stability of the model surface in ellipsometry measurements and the Ca(2+)-dependent binding of lipoproteins at the cell-based substrate.
