Osteoporosis is the most common metabolic bone disease and goes largely undiagnosed throughout the world, due to the inaccessibility of DXA machines. Multivariate analyses of serum bone turnover markers were evaluated in 226 Orange County, California, residents with the intent to determine if serum osteocalcin and serum pyridinoline cross-links could be used to detect the onset of osteoporosis as effectively as a DXA scan. Descriptive analyses of the demographic and lab characteristics of the participants were performed through frequency, means and standard deviation estimations. We implemented logistic regression modeling to find the best classification algorithm for osteoporosis. All calculations and …

Direct Quantification Of Deubiquitinating Enzyme Activity In Single Intact Cells, Nora Safabakhsh

LSU Doctoral Dissertations

Challenges in drug efficacy occur during the treatment of most types of cancer due to the heterogeneity of the tumor microenvironment. This has led to the development of personalized medicine. Due to the clinical success of the proteasome inhibitors Bortezomib and Carfilzomib in treatment of multiple myeloma, interest has shifted towards molecularly-targeted chemotherapeutics for ubiquitin-proteasome system (UPS). Deubiquitinating enzymes (DUBs) are an essential part of this pathway which have been found to promote Bortezomib resistance in multiple myeloma patients. Unfortunately, there is a lack of specific, high throughput biochemical assays to characterize DUB activity in patient samples before and after …

The Impact Of The Nurse Practitioner In Pre-Admission Testing: A Comparative Review, Laurel A. Robinson

DNP Projects

Abstract

PURPOSE: The purpose of this study was to compare the efficiency of pre-admission testing (PAT) surgical clinic pre and post implementation of the APRN for patient assessment. Cancellation and delay occurrences for scheduled surgeries will be compared during two time periods on patients on the surgical schedule at Norton Women and Children’s Hospital (NWC).

METHODS: This study was a single-center, pre and post implementation retrospective comparative study of the impact of the NP led PAT unit at Norton Women and Children’s Hospital (NWC) in terms of delay and cancellation rates for day-of-surgery. The sample consisted of 411 patients for …
