Insulin activation of phosphoinositide 3-kinase (PI3K) signaling regulates glucose homeostasis through the production of phosphatidylinositol 3,4,5-trisphosphate (PIP3). The dual-specificity phosphatase and tensin homolog deleted on chromosome 10 (PTEN) blocks PI3K signaling by dephosphorylating PIP3, and is inhibited through its interaction with phosphatidylinositol 3,4,5-trisphosphate-dependent Rac exchanger 2 (P-REX2). The mechanism of inhibition and its physiological significance are not known. Here, we report that P-REX2 interacts with PTEN via two interfaces. The pleckstrin homology (PH) domain of P-REX2 inhibits PTEN by interacting with the catalytic region of PTEN, and the inositol polyphosphate 4-phosphatase domain of P-REX2 provides high-affinity binding to the postsynaptic …

Effectiveness Of Community Health Workers (Chws) In Coordinating Diabetes Self Management Education (Dsme) For High-Need Appalachian Clients, Frances J. Feltner, Willie Bates

Center of Excellence in Rural Health Presentations

Objective

Examine effectiveness of CHWs in supporting a nurse-led DSME intervention among clients who are characterized by high rates of poverty and poor education.

Methods

Study Population/Research Design: New Kentucky Homeplace clients (3,217) ages 18-65+ from a 26-county study area who were processed prior to study starting date July 1, 2011. The 30.6% (983) of clients who had been told by a health professional they were diabetic, could speak English, and were willing to sign IRB consent were eligible to participate. Women who were diagnosed with diabetes during pregnancy were not eligible. Clients were able to enroll on a first-come …

An Investigation Of Perinatal Polychlorinated Biphenyl Exposure On Body Composition And Glucose Homeostasis, Cetewayo S. Rashid

Theses and Dissertations--Nutritional Sciences

Recent advancements have uncovered environmental contributions to obesity and diabetes etiology. In fact, perinatal malnutrition resulting in low birth weight (LBW) has been shown to correlate with later life obesity and impaired glucose tolerance in aged offspring. LBW can result from a myriad of developmental perturbations including macronutrient restriction, hypoxia, maternal stress and toxin exposure.

Polychlorinated biphenyls (PCBs) are ubiquitous environmental pollutants that bioaccumulate in the food chain resulting in dietary exposure in humans. Maternal and cord blood PCB levels are inversely associated with birth weight, and recent studies indicate that perinatal exposures to PCBs contribute to gender-specific obesity development …

Educational Materials And Brief Counseling Improve Diabetes Knowledge And Self-Efficacy, Tamara K. Wellman

DNP Projects

Purpose: The purpose of this study was to see if education and counseling of the Appalachian individual with diabetes and a family member/friend would improve knowledge of the disease and self-efficacy of the patient in regard to their diabetes care.

Setting: The setting was one of eight primary care offices of Our Lady of Bellefonte Hospital, Bon Secours, located in the Ashland, Kentucky.

Design: A pilot study of descriptive, comparative design was used.

Subjects: Data were collected from a convenience sample of patients with type 2 diabetes (n=15) that were established at the primary care office and their family members/friends …
