Triple Negative Breast Cancer In An Appalachian Region: Exponential Tumor Grade Increase With Age Of Diagnosis, Gina Sizemore, Toni Marie Rudisill

Journal of Appalachian Health

Introduction: Triple negative breast cancer is an aggressive breast cancer with decreased five-year survival, increased risk for recurrence, and higher risk for metastases. Unlike other breast cancers, it has no targeted treatment and has heterogeneous genetics which make classification and treatment difficult.

Purpose: The purpose of our research was to compare triple negative breast cancer to non-triple negative breast cancer to identify key epidemiologic factors that might lead to improved basic science directives for biomarkers, treatments, and classification.

Methods: The state cancer registry was used to provide the first West Virginia state-wide population evaluation of triple negative breast cancer.

Venoarterial Extracorporeal Membrane Oxygenation For Cardiogenic Shock: A Retrospective Analysis Based On The Etiology Of Shock, Andrew Burchett, Thomas Tribble, Richard Charnigo, Susan Smyth, Maya Guglin

The VAD Journal

Abstract:

Background: We performed a retrospective analysis to evaluate the efficacy of VA-ECMO support in cardiogenic shock based on various etiologies.

Methods: We retrospectively analyzed 99 patients supported with VA-ECMO from January 1, 2012 to January 1, 2015. Outcomes included survival to discontinuation of VA-ECMO support and survival to hospital discharge. The etiologies of cardiogenic shock included cardiac arrest (CPR), acute myocardial infarction (AMI), decompensated congestive heart failure (CHF), pulmonary embolism (PE), right ventricular failure (RVF) not secondary to an acute pulmonary embolism, and post-cardiotomy syndrome (PCS). The PCS group was used as a reference group; odds ratios were estimated …

Fulminant Necrotizing Eosinophilic Myocarditis: A Case Report And Comprehensive Literature Review, Bennet George, Matthew Hager, Virgilius Cornea, William O'Connor, Maya Guglin

The VAD Journal

Acute eosinophilic myocarditis is a relatively rare disorder with serious morbidity and mortality. Due to its infrequency, standardized management guidelines are wanting. We present a case of acute, necrotizing eosinophilic myocarditis requiring several levels of critical care. We reviewed similar cases reported in the literature to highlight common clinical features, describe natural disease course and associated complications, and review varying approaches to medical therapy.

Cardiomems™ In Lvad Patients: A Case Series, Maya Guglin, Bennet George, Sarah Branam, Amanda Hart

The VAD Journal

Patients with a left ventricular assist device (LVAD) commonly encounter issues with volume status post-implant. Volume overload can result from incomplete compensation of left ventricular failure or from right ventricular failure. The CardioMEMS™ intracardiac hemodynamic monitoring device is an area of growing interest regarding the management of chronic congestive heart failure, however, its utility has not been serially investigated in patients with an LVAD. We present a case series of patients with ventricular assist devices care for at our institution in which the CardioMEMS™ device aided in the management of volume status and pump performance.

Distributed Task Related Bold Signal During Auditory Sub-Second Timing, Yuriy Bronshteyn

Kaleidoscope

The brain's input/output functions depend heavily on temporal processing. We sought to identify regions of the brain active in task performance during temporal discrimination of a sub-second auditory interval. We presented ten subjects with 40 paired tones and asked them to judge whether these comparison intervals were longer or shorter than a 100 ms standard. We then localized correlations between the Blood Oxygenation Level Dependent signal and task performance across subjects using event-related functional magnetic resonance imaging. We saw no task-related frontal cortex activation and significant activation of traditional auditory areas. Auditory regions included the bilateral superior and middle temporal …

Role Of Cytoskeletal Dynamics In Platelet Arf6 Activation, Brett Taylor Begley

Kaleidoscope

Platelets undergo morphological changes upon activation, such as shape change and aggregation. These changes are known to be the result of actin remodeling, whereas the role of microtubule remodeling has been controversial. The objective of this study was to re-examine the role of actin and microtubule dynamics in platelet function. We used aggregometry to measure the effect of cytoskeletal inhibitors on platelet shape change, aggregation, and dense core release. Microtubule assembly was found to have no role in platelet function, because treatment with vinblastine or nocodazole had no effect on shape change, aggregation, or secretion. Microtubule disassembly was necessary for …

The Role Of Oxidative Stress In Alzheimer's Disease, Robin Petroze

Kaleidoscope

Over four million individuals in the United States currently suffer from Alzheimer's disease (AD), a devastating disorder of progressive dementia. Within the next several decades, AD is expected to affect over 22 million people globally. AD can only be definitively diagnosed by postmortem examination. Thus, investigation into the specific pathogenesis of neuronal degeneration and death in AD on a biochemical level is essential for both earlier diagnosis and potential treatment and prevention options. Overproduction of amyloid [3-peptide (A[3) in the brain leads to both free radical oxidative stress and toxicity to neurons in AD. My undergraduate biochemical studies with regard …
