Faculty, Staff and Students Publications

OBJECTIVE: It is controversial whether adults who are obese but "metabolically healthy" have cardiovascular disease (CVD) risk comparable with that of normal-weight adults. High-sensitivity cardiac troponin T (hs-cTnT), a biomarker of myocardial damage, is useful in characterizing subclinical CVD. We categorized obesity phenotypes and studied their associations with subclinical and clinical CVD and CVD subtypes, including heart failure (HF).

RESEARCH DESIGN AND METHODS: We conducted cross-sectional and prospective analyses of 9,477 adults in the Atherosclerosis Risk in Communities (ARIC) study. We used the Adult Treatment Panel III criteria and BMI to define obesity phenotypes as follows: metabolically healthy normal weight, …

A magnetic resonance (MR) biologic marker (biomarker) is a measurable quantitative characteristic that is an indicator of normal biological and pathogenetic processes or a response to therapeutic intervention derived from the MR imaging process. There is significant potential for MR biomarkers to facilitate personalized approaches to cancer care through more precise disease targeting by quantifying normal versus pathologic tissue function as well as toxicity to both radiation and chemotherapy. Both of which have the potential to increase the therapeutic ratio and provide earlier, more accurate monitoring of treatment response. The ongoing integration of MR into routine clinical radiation therapy (RT) …

Image Segmentation For Neuroscience: Lymphatics, Nazia Tabassum, Jie Wang, Michael Ferguson, Jasmin Herz, Michael Dong, Antoine Louveau, Jonathan Kipnis, Scott Thomas Acton

Division of Internal Medicine Faculty Papers & Presentations

A recent discovery in neuroscience prompts the need for innovation in image analysis. Neuroscientists have discovered the existence of meningeal lymphatic vessels in the brain and have shown their importance in preventing cognitive decline in mouse models of Alzheimer s disease. With age, lymphatic vessels narrow and poorly drain cerebrospinal fluid, leading to plaque accumulation, a marker for Alzheimer s disease. The detection of vessel boundaries and width are performed by hand in current practice and thereby suffer from high error rates and potential observer bias. The existing vessel segmentation methods are dependent on user-defined initialization, which is time-consuming and …

A Retrospective Study Of Admission Nt-Probnp Levels As A Predictor Of Readmission Rate, Length Of Stay And Mortality, Kunjan Udani, Dveet Patel, Andrew Mangano

HCA Healthcare Journal of Medicine

Introduction

Serum levels of pro-B-type natriuretic peptide (BNP) and N-terminal (NT) proBNP are measured at admission to assess the likelihood of acutely decompensated heart failure (ADHF). Elevated NT-proBNP levels on initial presentation are a reliable marker of ADHF. However, the prognostic significance of NT-proBNP levels measured on admission remains unknown. With a better understanding of how admitting NT-proBNP levels impacts readmission rates, length of stay and mortality, future prospective studies with specific interventions can be developed to reduce all-cause readmissions, shorten length of stay and reduce mortality.

Methods

In this retrospective study, we evaluated heart failure with reduced ejection fraction …
