Application variables included the strength of comparative statements in recommendation letters and the authors' academic ranks, membership status in the Alpha Omega Alpha Honor Medical Society, awards earned, volunteer activities, United States Medical Licensing Examination (USMLE) scores, advanced degrees, publications, and completion of a residency program ranked in the top 6 in the …

Importance Of Persistent Right-To-Left Shunt After Patent Foramen Ovale Closure In Cryptogenic Stroke Patients, Lu He, Gesheng Cheng, Yajuan Du, Yushun Zhang

The Texas Heart Institute Journal

Percutaneous closure of patent foramen ovale (PFO) is widely performed to prevent recurrent stroke or transient ischemic attack in patients with cryptogenic stroke. However, the influence of different degrees of right-to-left shunting (RLS) has rarely been reported.

We retrospectively evaluated the cases of 268 patients with cryptogenic stroke who underwent PFO closure at our hospital from April 2012 through April 2015. In accordance with RLS severity, we divided the patients into 2 groups: persistent RLS during normal breathing and the Valsalva maneuver (n=112) and RLS only during the Valsalva maneuver (n=156). Baseline characteristics, morphologic features, and procedural and follow-up data …

Platypnea-Orthodeoxia Syndrome Caused By An Intracardiac Shunt, Sanket P Borgaonkar, Wilson W Lam, Mehdi Razavi, Dhaval R Parekh

Faculty, Staff and Students Publications

Platypnea-orthodeoxia syndrome, a rare condition characterized by posture-related dyspnea, is usually caused by an intracardiac shunt, hepatopulmonary syndrome, or shunting resulting from severe pulmonary disease. We report the case of a 33-year-old woman who presented with increasing dyspnea and oxygen desaturation when she sat up or arose. Our diagnosis was platypnea-orthodeoxia syndrome. A lead of a previously implanted pacemaker exacerbated a severe tricuspid regurgitant jet that was directed toward the patient's intra-atrial septum. Percutaneous closure of a small secundum atrial septal defect eliminated right-to-left shunting and substantially improved the patient's functional status. In addition to this case, we discuss this …

Prospects For Rnai Therapy Of Covid-19, Hasan Uludağ, Kylie Parent, Hamidreza Montazeri Aliabadi, Azita Haddadi

Pharmacy Faculty Articles and Research

COVID-19 caused by the SARS-CoV-2 virus is a fast emerging disease with deadly consequences. The pulmonary system and lungs in particular are most prone to damage caused by the SARS-CoV-2 infection, which leaves a destructive footprint in the lung tissue, making it incapable of conducting its respiratory functions and resulting in severe acute respiratory disease and loss of life. There were no drug treatments or vaccines approved for SARS-CoV-2 at the onset of pandemic, necessitating an urgent need to develop effective therapeutics. To this end, the innate RNA interference (RNAi) mechanism can be employed to develop front line therapies against …

Characterizing Recurrence Following Hybrid Ablation In Patients With Persistent Atrial Fibrillation, David C. Kress, Lynn Erickson, Tadele W. Mengesha, David Krum, Jasbir Sra

Journal of Patient-Centered Research and Reviews

Purpose: It is It is widely accepted that atrial fibrillation (AF) accounts for half of arrhythmia recurrences following endocardial catheter ablation of AF. An epicardial-endocardial approach (hybrid) has emerged as an alternative to endocardial ablation alone for the treatment of AF, yet recurrence after a hybrid procedure has not been well characterized. This retrospective study is aimed at characterizing recurrence following hybrid ablation for patients with persistent AF.

Methods: Patients with persistent AF (N = 108) received both endocardial and epicardial ablation of the posterior left atrial wall using catheter ablation and a small midline surgical approach (hybrid). Presence of …

Do Adults Utilizing Intermittent Fasting Improve Lipids More Than Those Following A Restricted-Calorie Diet? A Clin-Iq, Mitchell A. Sanford, Tracy S. Sanford, K. F. Campbell, Dustin Davis, Tammy Tandberg, L. N. Eagle Road

Journal of Patient-Centered Research and Reviews

With approximately 95 million Americans diagnosed with high cholesterol, and many searching for a nonmedicinal treatment, intermittent fasting as a method to improve health has become increasingly popular in the lay public. We conducted a clinical inquiry to determine whether intermittent fasting is superior to a low-calorie diet in improving lipids, searching the Cochrane, EBSCOhost, Embase, MEDLINE, and Scopus databases using the terms intermittent fasting, lipids, and calorie-restricted diet. Studies that included surgical weight loss or medicine-assisted weight loss were excluded. We identified 6 published studies, 5 of which were randomized controlled trials. In reviewing the selected studies, …

A Rare Case Of Constrictive Pericarditis As Initial Manifestation Of Paediatric Anaplastic Large Cell Lymphoma Requiring Urgent Pericardiectomy, Sara Iqbal, Abdul Ahad Sohail, Narmeen Asif, Muhammad Rahil Khan, Sabeehuddin Siddique, Saulat Fatimi

Section of Cardiothoracic Surgery

Constrictive pericarditis (CP) is a rare end stage inflammatory disorder affecting both parietal and visceral pericardium leading to a right heart failure. Malignancy is the least common cause of CP. Anaplastic large cell lymphoma (ALCL) accounts for 10-15% of all Non-Hodgkin lymphomas in children. Very few case reports have reported ALCL that is involving the heart and only two have been published involving pericardium but all were managed medically. We present an interesting case of an 11 year old child who presented with an effusive CP that required urgent Pericardiectomy for managing right heart failure. His histopathology was positive for …

Office of the Provost

Background: While optimal cardiovascular risk factor (CRF) profile is associated with lower mortality, morbidity, and healthcare expenditures among individuals with atherosclerotic cardiovascular disease (ASCVD), less is known regarding its impact on financial hardship from medical bills. Therefore, we assessed whether an optimal CRF profile is associated with a lower burden of financial hardship from medical bills and a reduction in cost-related barriers to health.
Methods: We used a nationally representative sample of adults between 18 and 64 years from the National Health Interview Survey between 2013 and 2017. We assessed ASCVD status and the number of risk factors to categorize …

Thrombospondin-1 Plays An Essential Role In Yes-Associated Protein Nuclear Translocation During The Early Phase Of Trypanosoma Cruzi Infection In Heart Endothelial Cells, Ashutosh Arun, Kayla J. Rayford, Ayorinde Cooley, Girish Rachakonda, Fernando Villalta, Siddharth Pratap, Maria F. Lima, Nader Sheibani, Pius N. Nde

Publications and Research

The protozoan parasite Trypanosoma cruzi is the causative agent of Chagas disease. This neglected tropical disease causes severe morbidity and mortality in endemic regions. About 30% of T. cruzi infected individuals will present with cardiac complications. Invasive trypomastigotes released from infected cells can be carried in the vascular endothelial system to infect neighboring and distant cells. During the process of cellular infection, the parasite induces host cells, to increase the levels of host thrombospondin-1 (TSP-1), to facilitate the process of infection. TSP-1 plays important roles in the functioning of vascular cells, including vascular endothelial cells with important implications in cardiovascular …

A Counterpoint Paper: Comments On The Electrocardiographic Part Of The 2018 Fourth Universal Definition Of Myocardial Infarction Endorsed By The International Society Of Electrocardiology And The International Society For Holter And Noninvasive Electrocardiology, Yochai Birnbaum, Miguel Fiol, Kjell Nikus, Javier Garcia Niebla, Ljuba Bacharova, Sergio Dubner, Wojciech Zareba, Peter W Macfarlane, Antonio Luiz Ribeiro, Iwona Cygankiewicz, Antoni Bayes De Luna

Faculty, Staff and Students Publications

The Fourth Universal Definition of Myocardial Infarction (FUDMI) focuses on the distinction between nonischemic myocardial injury and myocardial infarction (MI), along with the role of cardiovascular magnetic resonance, in order to define the etiology of myocardial injury. As a consequence, there is less emphasis on updating the parts of the definition concerning the electrocardiographic (ECG) changes related to MI. Evidence of myocardial ischemia is a prerequisite for the diagnosis of MI, and the ECG is the main available tool for (a) detecting acute ischemia, (b) triage, and (c) risk stratification upon presentation. This review focuses on multiple aspects of ECG …

Primary cilia are shown to have membrane swelling, also known as ciliary bulbs. However, the role of these structures and their physiological relevance remains unknown. Here, it is reported that a ciliary bulb has extracellular vesicle (EV)‐like characteristics. The ciliary extracellular‐like vesicle (cELV) has a unique dynamic movement and can be released by mechanical fluid force. To better identify the cELV, differential multidimensional proteomic analyses are performed on the cELV. A database of 172 cELV proteins is generated, and all that examined are confirmed to be in the cELV. Repressing the expression of these proteins in vitro and in vivo …
