Development of chemoresistance is the main reason for failure of clinical management of multiple myeloma (MM), but the genetic and epigenetic aberrations that interact to confer such chemoresistance remains unknown. In the present study, we find that high steroid receptor coactivator-3 (SRC-3) expression is correlated with relapse/refractory and poor outcomes in MM patients treated with bortezomib (BTZ)-based regimens. Furthermore, in immortalized cell lines, high SRC-3 enhances resistance to proteasome inhibitor (PI)-induced apoptosis. Overexpressed histone methyltransferase NSD2 in patients bearing a t(4;14) translocation or in BTZ-resistant MM cells coordinates elevated SRC-3 by enhancing its liquid-liquid phase separation to supranormally modify histone …

Length Of Hospital Stay Following Temporary Pacing Post-Transcatheter Valve Replacement, Sean Mccarthy, Marvin Eng M.D.

Medical Student Research Symposium

Transcatheter valve replacement (TVR) provides a minimally invasive method of valve replacement. During TVR, conduction abnormalities can develop, but only some will require permanent pacing, and use of temporary pacing provides immediate support until a decision of temporary pacing is made. Henry Ford Health System has two methods of pacing lead placement: balloon tipped leads and screw-in leads. Currently, the impact of different types of temporary pacing leads on recovery time is still unknown. This project investigated the differences in the length of hospital and ICU stay between patients who received the balloon tipped and screw-in leads. Data was collected …

Cardiac Arrest Clinical Outcomes In Patients Presenting With Opioid Overdose, Andrew Toron, Morgan Hutchinson, Md, David Gaieski Feb 2021

Cardiac Arrest Clinical Outcomes In Patients Presenting With Opioid Overdose, Andrew Toron, Morgan Hutchinson, Md, David Gaieski

Phase 1

Introduction: Understanding opioids and their potential to cause cardiac arrests is integral in learning how to lower mortality rates in patients who overdose on them. Few studies have specifically examined the association of out-of-hospital cardiac arrests with opioid overdoses. We hypothesized that cardiac arrests caused by opioid overdoses will result in longer hospital stays and a higher mortality rate than other cardiac arrests.

Methods: This study is a secondary analysis of data from the Cardiac Arrest Registry to Enhance Survival. Data regarding 35 patients who presented to Jefferson and Methodist hospitals with out-of-hospital cardiac arrests due to opioid overdose …

Peripheral artery disease (PAD) is associated with impaired lower extremity function. We hypothesized that contrast-enhanced magnetic resonance imaging (CE-MRI) based arterial signal enhancement (SE) measures are associated with markers of PAD. A total of 66 participants were enrolled, 10 were excluded due to incomplete data, resulting in 56 participants for the final analyses (36 PAD, 20 matched controls). MR imaging was performed postreactive hyperemia using bilateral thigh blood-pressure cuffs. First pass-perfusion images were acquired at the mid-calf region with a high-resolution saturation recovery gradient echo pulse sequence, and arterial SE was measured for the lower extremity arteries. As expected, peak …

Accuracy Of Procalcitonin Levels For Diagnosis Of Culture-Positive Sepsis In Critically Ill Trauma Patients: A Retrospective Analysis, Aisha Bakhtiar, Syed Jawad Haider Kazmi, Muhammad Sohaib Asghar, Muhammad Nadeem Khurshaidi, Salman Mazhar, Noman A. Khan, Nisar Ahmed, Farah Yasmin, Rabail Yaseen, Maira Hassan

Section of Cardiothoracic Surgery

Background: Abdominal trauma and intra-abdominal sepsis are associated with significant morbidity and mortality. Microcirculation in the gut is disrupted in hemorrhagic and septic shock leading to tissue hypoxia, and the damaged gut acts as a reservoir rich in inflammatory mediators and provides a continual source of inflammation to the systemic circulation leading to sepsis. Sepsis is defined as the presence (probable or documented) of infection together with a systemic inflammatory response to infection. Blood culture is commonly considered to be the preferred approach for diagnosing sepsis, although it is time-consuming, that is, reports are normally available only after 12-48 hours. …

Medical Student Research Symposium

The cardiovascular health of those infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) plays a major role in rates of hospitalization, mortality risk, and rates of mechanical ventilation. In patients with COVID-19, acute myocardial injury and history of cardiovascular disease are both independently established risk factors for poor patient prognosis. In addition to myocardial injury, numerous acute cardiovascular manifestations of COVID-19 disease have been identified. Previous work on this topic typically focused either upon a general description of the acute cardiovascular manifestations and sequalae of COVID-19, or upon broad-based clinical outcomes associated with COVID-19 in patients with history of …

Traumatic brain injury-induced coagulopathy (TBI-IC) causes life-threatening secondary intracranial bleeding. Its pathogenesis differs mechanistically from that of coagulopathy arising from extracranial injuries and hemorrhagic shock, but it remains poorly understood. We report results of a study designed to test the hypothesis that von Willebrand factor (VWF) released during acute TBI is intrinsically hyperadhesive because its platelet-binding A1-domain is exposed and contributes to TBI-induced vascular leakage and consumptive coagulopathy. This hyperadhesive VWF can be selectively blocked by a VWF A2-domain protein to prevent TBI-IC and to improve neurological function with a minimal risk of bleeding. We demonstrated that A2 given through …

Algorithm For Cavo-Tricuspid Isthmus Flutter On Surface Ecgs: The Actions Study., Daniel Frisch, Eitan Frankel, Deanna Gill, Jad Al Danaf

Division of Cardiology Faculty Papers

OBJECTIVE: Cavo-tricuspid isthmus atrial flutter (CTI-AFL) is an important arrhythmia to recognise because there is a highly effective and relatively low-risk ablation strategy. However, clinical experience has demonstrated that providers often have difficulty distinguishing AFL from atrial fibrillation.

METHODS: We developed a novel ECG-based three-step algorithm to identify CTI-AFL based on established CTI flutter characteristics and verified on consecutive ablation cases of typical flutter, atypical flutter and atrial fibrillation. The algorithm assesses V1/inferior lead F-wave concordance, consistency of P-wave morphology and the presence of isoelectric intervals in the inferior leads. In this observation study, the algorithm was validated on a …

Gill Heart & Vascular Institute Faculty Publications

Stem cell-based cardiac therapies have been extensively studied in recent years. However, the efficacy of cell delivery, engraftment, and differentiation post-transplant remain continuous challenges and represent opportunities to further refine our current strategies. Despite limited long-term cardiac retention, stem cell treatment leads to sustained cardiac benefit following myocardial infarction (MI). This review summarizes the current knowledge on stem cell based cardiac immunomodulation by highlighting the cellular and molecular mechanisms of different immune responses to mesenchymal stem cells (MSCs) and their secretory factors. This review also addresses the clinical evidence in the field.

Gill Heart & Vascular Institute Faculty Publications

Group B Streptococcus (GBS) remains the most common Gram‐positive bacterium causing neonatal meningitis and GBS meningitis continues to be an important cause of mortality and morbidity. In this study, we showed that GBS penetration into the brain occurred initially in the meningeal and cortex capillaries, and exploits a defined host cell signaling network comprised of S1P2, EGFR, and CysLT1. GBS exploitation of such network in penetration of the blood–brain barrier was demonstrated by targeting S1P2, EGFR, and CysLT1 using pharmacological inhibition, gene knockout and knockdown cells, and gene knockout animals, as well as interrogation of the …


Decreased Inr On Lvad Support: To Bridge Or Not To Bridge?, Maya Guglin Jan 2021

Decreased Inr On Lvad Support: To Bridge Or Not To Bridge?, Maya Guglin

The VAD Journal

In volume 6, issue 2 of The VAD Journal, we published a paper by Rainess et al. who reported their experience with managing subtherapeutic INRs, mostly in patients with HeartMate II (Thoratec, Pleasanton, CA). Although, the cohort did include some HeartMate 3-supported patients. In their program (Wake Forest University), pharmacists manage anticoagulation according to the institutional protocol, which allows bridging with low molecular weight heparin when INR decreases to less than 1.8. The study is unique because the patients did NOT require interruption of anticoagulation for any purpose. In all instances, the INR decreased because of dietary variations, recent …
