Biomechanical dysregulation of SGK-1 dependent aortic pathologic markers in hypertension.

Introduction: In hypertension (HTN), biomechanical stress may drive matrix remodeling through dysfunctional VSMC activity. Prior evidence has indicated VSMC tension-induced signaling through the serum and glucocorticoid inducible kinase-1 (SGK-1) can impact cytokine abundance. Here, we hypothesize that SGK-1 impacts production of additional aortic pathologic markers (APMs) representing VSMC dysfunction in HTN.

Integrating Ultrasound-Derived Carotid Artery Stiffness in the Assessment of Cardiovascular Risk.

Historically, pulse wave velocity (PWV) has been used to measure vascular stiffness, but is limited in its utility when certain vascular disease states are present, such as aneurysm or iliac stenosis. PWV can therefore only provide reliable assessment of global vascular stiffness in limited vascular pathology. Speckle tracking is a method of post-hoc ultrasound image analysis that can measure vascular stiffness in a more comprehensive manner.

High-Expenditure Pharmaceutical Use Among Children in Medicaid.

Background And Objectives: Medication use may be a target for quality improvement, cost containment, and research. We aimed to identify medication classes associated with the highest expenditures among pediatric Medicaid enrollees and to characterize the demographic, clinical, and health service use of children prescribed these medications.

Methods: Retrospective, cross-sectional study of 3 271 081 Medicaid-enrolled children.

A nurse-led approach to developing and implementing a collaborative count policy.

During the 2007 meeting of the Child Health Corporation of America Operating Room Director's Forum, members identified two major discrepancies in surgical count policies among the member hospitals: variations for instrument counts in pediatrics and exceptions to radiographic verification when needle counts were incorrect. The group agreed to collaboratively develop a pediatric count policy based on directors' expertise and current literature to help improve count practices. The task force members reviewed the literature as well as count policies from 30 member hospitals to identify and combine best practices and to create a single, standardized count policy.

Perceived control and negative affect predict expected and experienced acute clinical pain: a structural modeling analysis.

Objectives: Risk factors for elevated levels of clinical and experimental pain have been shown to be independently predicted by the individual's perception of personal control, negative emotional states, and pain expectancy. In this study we examine the mutual simultaneous association of these factors in the experience of dental extraction pain.

Methods: Using structural equation modeling we examined the relationship between desired and predicted personal control, negative emotional state and the expectation of pain to predict worst treatment pain.
