Spontaneous Iliac Arteriovenous Fistula, High-Output Heart Failure, And Cardiac Arrest, J. Maxwell Piraneo, Russell Mordecai, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

High-output heart failure is a potentially life-threatening condition that can lead to cardiac arrest. The most common causes of this condition are obesity, liver disease, arteriovenous shunts, lung disease, and myeloproliferative disorders, however the exact prevalence remains uncertain [1]. Here we describe an unusual case of cardiac arrest as a consequence of high-output heart failure, secondary to rupture of an iliac artery aneurysm into the common iliac vein, with arteriovenous (AV) fistula formation.

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (R_CAP) and length (L_CAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …

Thrompella: Acute Impella Thrombosis During Ecpella Support, Faris Araj, Hurst M. Hall, Amy E. Hackmann

The VAD Journal

We present a case of acute Impella thrombosis during Ecpella support in a 48-year-old man listed for a heart transplant. After two weeks of Ecpella support, echocardiography revealed a 2.6 x 1.1 cm mobile thrombus attached to the Impella inlet (Video). The Impella and attached thrombus were pulled across the aortic valve into the descending aorta and removed without systemic thromboembolism. Due to the ongoing need for left ventricular venting, a new Impella CP was placed.

Attitudes Toward Personal Health Data Sharing Among People Living With Sickle Cell Disorder, Exemplar For Study Of Rare Disease Populations, Rebecca Baines, Sebastian Stevens, Zainab Garba-Sani, Arunangsu Chatterjee, Daniela Austin, Simon Leigh

Journal of Patient-Centered Research and Reviews

Purpose: Rare conditions are often poorly understood, creating barriers in determining the value treatments can provide. This study explored barriers and facilitators to personal health data sharing among those with one particular group of rare hematologic disorders, ie, sickle cell disorder (SCD) and its variants.

Methods: A single online focus group among those > 18 years of age and living with SCD was conducted. Participants (N = 25) were recruited through a United Kingdom-based SCD charity. Discussions were transcribed verbatim, with data therein analyzed using inductive thematic analysis.

Results: Five primary motivators for sharing health data were identified: improving awareness; knowing …

Quality Assurance In Extracorporeal Membrane Oxygenation Patients, Ruzica Mrkonjic

The VAD Journal

The selection of patients for extracorporeal membrane oxygenation (ECMO) support is a critical component of any perfusion program. Teams must evaluate when to start the support, how long to support the patient, and when is the ideal time to wean. The timing of ECMO support is debated. While some programs emphasize prompt timing, others suggest the conservative approach is better (>7 hours). Delaying ECMO support could increase complications; thus, more evidence has been attained for prompt support. Importantly, complications are common with ECMO support. Despite advances in ECMO support over the last ten years, bleeding remains a high risk. …

The Effects Of Demographics And Risk Factors On The Morphological Characteristics Of Human Femoropopliteal Arteries, Sayed Ahmadreza Razian, Majid Jadidi, Alexey Kamenskiy

UNO Student Research and Creative Activity Fair

Background: Disease of the lower extremity arteries (Peripheral Arterial Disease, PAD) is associated with high morbidity and mortality. During disease development, the arteries adapt by changing their diameter, wall thickness, and residual deformations, but the effects of demographics and risk factors on this process are not clear.

Methods: Superficial femoral arteries from 736 subjects (505 male, 231 female, 12 to 99 years old, average age 51±17.8 years) and the associated demographic and risk factor variables were used to construct machine learning (ML) regression models that predicted morphological characteristics (diameter, wall thickness, and longitudinal opening angle resulting from the …

Delayed Thoracodorsal Artery Perforator Free Flap For Calcaneal Degloving Injury Reconstruction, Mallorie L. Huff, Ahmed M. Mansour, Mamtha S. Raj, Robert J. Allen, Sean J. Wallace

School of Medicine Faculty Publications

The thoracodorsal artery perforator (TDAP) flap has a long vascular pedicle that is ideal for lower extremity reconstruction, but it generally relies on the presence of a dominant septocutaneous perforator vessel. Surgical delay optimizes flap survival by creating relative ischemia to augment perforator vessels. In this report, we describe the use of a delayed free TDAP flap in the setting of an absent dominant perforator vessel for the reconstruction of a calcaneal degloving injury. A 22-year-old actively smoking patient with a body mass index of 33.5 presented with a nonhealing left heel wound with overlying necrotic changes after traumatic degloving …

Recurrent Spontaneous Coronary Artery Dissection: A Case Of Triple Trouble, Sumit Khurana, Jessica Kaushal, Dhruv Markan, John C. Wang, Antony Kaliyadan, Christopher Haas, Amrit Devkota

Journal of Community Hospital Internal Medicine Perspectives

SCAD (Spontaneous Coronary Artery Dissection) is a rare disorder which rarely recurs. It is increasingly diagnosed as a cause for acute coronary syndrome (ACS) with limited insight into its pathophysiology and treatment. Lack of randomized trials and consensus guidelines make this a unique and challenging disease to manage. We describe a complex case of recurrent idiopathic SCAD with prior history of NSTE-ACS (Non-ST elevation Acute Coronary Syndrome) and discuss its management based on current clinical practices.

A Case Of Congenital Coronary Sinus Ostial Atresia With Persistent Left Superior Vena Cava, Laura Onderko, Thomas A. Miller, Sean Novak, Jeffrey Rosenblatt

Journal of Maine Medical Center

Introduction: The coronary sinus is responsible for venous drainage of the heart. Congenital anomalies of the coronary sinus are rare and typically associated with other anomalies, such as atrial septal defects or other congenital heart malformations.

Clinical Findings: We present a case of incidentally found atresia of the coronary sinus ostium with associated persistent left superior vena cava. This case involved a 52-year-old patient who initially presented with a supraventricular tachycardia and elevated troponin.

Clinical Course: The patient underwent cardiac workup with a coronary computed tomographic angiography scan. This scan showed no obstructive coronary artery disease, but did show congenital …

Fluid Management In Septic Patients With Pulmonary Hypertension, Review Of The Literature, Blerina Asllanaj, Elizabeth Benge, Jieun Bae, Yi Mcwhorter

School of Medicine Faculty Research

The management of sepsis in patients with pulmonary hypertension (PH) is challenging due to significant conflicting goals of management and complex hemodynamics. As PH progresses, the ability of right heart to perfuse lungs at a normal central venous pressure (CVP) is impaired. Elevated pulmonary vascular pressure, due to pulmonary vasoconstriction and vascular remodeling, opposes blood flow through lungs thus limiting the ability of right ventricle (RV) to increase cardiac output (CO) and maintain adequate oxygen delivery to tissue. In sepsis without PH, avoidance of volume depletion with intravascular volume replacement, followed by vasopressor therapy if hypoperfusion persists, remains the cornerstone …

H2s, Sg-1002, Protects Against Myocardial Oxidative Damage And Hypertrophy In Vitro Via Induction Of Cystathionine Β-Synthase And Antioxidant Proteins, Rahib K. Islam, Erinn Donnelly, Erminia Donnarumma, Fokhrul Hossain, Jason D. Gardner, Kazi N. Islam

School of Medicine Faculty Publications

Endogenously produced hydrogen sulfide (H2S) is critical for cardiovascular homeostasis. Therapeutic strategies aimed at increasing H2S levels have proven cardioprotective in models of acute myocardial infarction (MI) and heart failure (HF). The present study was undertaken to investigate the effects of a novel H2S prodrug, SG-1002, on stress induced hypertrophic signaling in murine HL-1 cardiac muscle cells. Treatment of HL-1 cells with SG-1002 under serum starvation without or with H2O2 increased the levels of H2S, H2S producing enzyme, and cystathionine β-synthase (CBS), as well as antioxidant protein levels, such as super oxide dismutase1 (SOD1) and catalase, and additionally decreased oxidative …

What Did We Learn About Vads In 2022?, Maya Guglin

The VAD Journal

This is our 9^th annual literature review on mechanical circulatory support devices. Our previous reports were well received by the readers.

In this paper, we summarized the most interesting and important, from our standpoint, publications from 2022. There may be some slight overlap with the end of 2021 because some papers were published online first, and the year of the publication changed when they became available in print.

For the sixth time, we wrote a section on extracorporeal membrane oxygenation (ECMO) which primarily addresses new developments in veno-arterial ECMO.

Readers who wish to supplement this review, argue with the …

Medical Professionals’ Perspective On Safety And Efficacy Of Early Mobilization In Acute Heart Failure Patients, Kevin Triangto, Febrian M. Santausa, Basuni Radi, Bambang Budi Siswanto

Journal of the Hong Kong College of Cardiology

Acute heart failure (HF) patients most of the time presents with hemodynamic instability, which often leads to prolonged bedrest. Newer studies had shown that early mobilization for HF patients would lead to better outcomes. However, the early mobilization practice has not always been done due to several barriers in the medical professionals’ perspective, especially regarding safety and efficacy. Prior studies had shown that medical professionals’ views would greatly affect patients’ perspectives, especially in HF rehabilitation. This study is aimed to describe medical professionals’ views on the safety of early mobilization for HF. It was then revealed that General Practitioners’ (GP) …

Short-Term Removal Of Exercise Impairs Glycemic Control In Older Adults: A Randomized Trial, Leryn J. Reynolds, Troy M. Williams, Joel E. Harden, Hannah M. Twiddy, Monica L. Kearney

Human Movement Studies & Special Education Faculty Publications

Postprandial glycemia (PPG) predicts cardiovascular disease, and short-term physical inactivity increases PPG in young, active adults. Whether this occurs in older, active adults who may be more prone to bouts of inactivity is unknown. This study determined if postprandial interstitial glucose (PPIG) was impaired in active older adults following the removal of exercise for 3 days (NOEX) compared to active young adults. In this randomized, crossover study, 11 older (69.1 ± 1.9 years) and 9 young (32.8 ± 1.8 years) habitually active (≥90 min/week of exercise) adults completed 3-days of NOEX and 3-days of normal habitual exercise (EX), separated by …

Training Specificity And Functional Performance In Collegiate Cheerleaders, Carly Routman

College of Graduate Studies: Theses & Dissertations

INTRODUCTION: Competitive collegiate cheerleading requires participants to be conditioned for explosive powerful movements. Studies have shown cheerleading is associated with a high incidence of catastrophic injury (Mueller, 2009; Boden, 2005; Xu et al., 2021). In response to high injury rates, studies have recommended strength and conditioning requirements to decrease the likelihood of injury due to the lack of cheer-specific training (Jacobson et al., 2004). Although it has been recommended for cheerleaders to receive formal strength training, many schools do not provide these resources to their cheerleading teams. PURPOSE: The purpose of this study was to determine if there are differences …

Exploring The Efficacy Of Mir-33 Antagonism In Promoting Regression Of Intracranial Atherosclerosis In A Nonhuman Primate Model, Peter Hecker

Theses and Dissertations--Pharmacology and Nutritional Sciences

Atherosclerosis, characterized by lipid accumulation and arterial inflammation, is a major contributor to global morbidity and mortality. Despite significant progress in understanding atherosclerosis in extracranial arteries, the study of intracranial atherosclerosis (ICAS) has been relatively neglected, despite its crucial role in stroke and vascular cognitive impairment. Challenges related to ICAS, including its location within the cranium and limited availability of suitable animal models, have hindered research progress in this area. Although nonhuman primates (NHPs) are commonly used for studying extracranial atherosclerosis, a comprehensive understanding of ICAS pathophysiology in these animals is lacking. By subjecting NHPs to a high-fat/cholesterol diet, we …
