Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente Mar 2019

Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente

Graduate Student Research Symposium

Usually not diagnosed until open laparotomy, aortoduodenalfistulas (ADF) are one of the rarest complications of intestinal transplant surgery. With an incidence rate of only 0.04% at autopsy and only 250 documented cases since the early 1800’s, aortoduodenal fistulas are the most deadly complications of intestinal transplantation with a mortality rate of 100% without surgical intervention. A 39 year old, two-time multi-visceral transplant African American female patient suffered from a primary aortoduodenal fistula formation in a primary modified multi-visceral transplant aortic stump graft site. With emergency open laparotomy repair, revascularization of the secondary multi-visceral transplant was performed, saving the life of …

Successful Extracorporeal Membrane Oxygenation In The Management Of Acute Respiratory Distress Syndrome And Cardiopulmonary Collapse Secondary To Amniotic Fluid Embolism, Sumon Roy, Nishit A. Biniwale, Venkata S. Pendela, Patricia Oates, Katrina Wojciechowski, Scott C. Feitell

The VAD Journal

Amniotic fluid embolism (AFE) is one of the most devastating complications of pregnancy that typically manifests as acute cardiopulmonary collapse during delivery or in the postpartum period. The potential role of extracorporeal membrane oxygenation (ECMO) as a management technique in severe cases of AFE remains largely unknown given the limited literature available. In this report, we present the first case, to our knowledge, of successful implementation of ECMO as a life-saving measure in a case of hemorrhagic shock due to postpartum bleeding complicated by severe AFE leading to acute respiratory distress syndrome (ARDS) ultimately requiring tracheostomy. Hemodynamic decompensation is often …

College of Osteopathic Medicine (TUN) Publications and Research

The diagnostic approach to thyroid cancer is one of the most challenging issues in oncology of the endocrine system because of its high incidence (3.8% of all new cancer cases in the US) and the difficulty to distinguish benign from malignant non-functional thyroid nodules and establish the cervical lymph node involvement during staging. Routine diagnosis of thyroid nodules usually relies on a fine-needle aspirate biopsy, which is invasive and often inaccurate. Therefore, there is an urgent need to identify novel, accurate, and non-invasive diagnostic procedures. Liquid biopsy, as a non-invasive approach for the detection of diagnostic biomarkers for early tumor …

Development Of A Novel Loop-Mediated Isothermal Amplification Method To Detect Guiana Extended-Spectrum (Ges) Β-Lactamase Genes In Pseudomonas Aeruginosa, Chika Takano, Mitsuko Seki, Dong Wook Kim, Humphrey Gardner, Robert E. Mclaughlin, Paul E. Kilgore, Kazunari Kumasaka, Satoshi Hayakawa

Department of Pharmacy Practice

Infections caused by multidrug-resistant Pseudomonas aeruginosa in hospitalized patients are often fatal, and nosocomial infections caused by Guiana extended-spectrum (GES) β-lactamase-producing strains are of growing concern. Several genotypes of the GES β-lactamase gene (blaGES) include a single missense mutation, a change from G to A at nucleotide position 493 (G493A) that changes glycine to serine; the mutant enzyme exhibits carbapenemase activity. Rapid and reliable identification of drug-resistance is important in clinical settings; however, culture methods remain the gold standard. Conventional and real-time PCR cannot identify carbapenemase-producing genotypes, and direct DNA sequencing is essential. We established …

Circulating tumor DNA (ctDNA) may serve as a surrogate to tissue biopsy for noninvasive identification of mutations across multiple genetic loci and for disease monitoring in melanoma. In this study, we compared the mutation profiles of tumor biopsies and plasma ctDNA from metastatic melanoma patients using custom sequencing panels targeting 30 melanoma-associated genes. Somatic mutations were identified in 20 of 24 melanoma biopsies, and 16 of 20 (70%) matched-patient plasmas had detectable ctDNA. In a subgroup of seven patients for whom matching tumor tissue and plasma were sequenced, 80% of the mutations found in tumor tissue were also detected in …

A 10-Year Review Of Opioid-Related Deaths At West Tennessee Regional Forensic Center: 2007-2017, Haley M. St John, Juliette Scantlebury Md

Longitudinal Scholar's Project

Prescription opioid deaths have tripled since 1999, and currently opioid overdose kills 115 Americans per day on average (1). Prior to 2014, prescription opioids have been the primary driver of opioid-related mortality. In recent years, the United States has seen a steady decline in the rate of opioid prescription. At the same time, there has been a significant increase in the number of deaths attributed to non-prescription opioids such as heroin, illicitly manufactured fentanyl, and fentanyl analogues. In 2017, among 70,237 drug overdose deaths nationally, 47,600 (67.8%) involved opioids, with increases across age groups, racial/ethnic groups, and county urbanization levels …


Can Nanotechnology Be The Leading Method In Detecting And Treating Cerebral Tumors?, Daniel D. Singh, Zuri Jules-Culver Jan 2019

Can Nanotechnology Be The Leading Method In Detecting And Treating Cerebral Tumors?, Daniel D. Singh, Zuri Jules-Culver

OUR Journal: ODU Undergraduate Research Journal

Nanotechnology refers to the manipulation or design of materials and structures with desired features in the 1nm–1000 nm size range. The blood brain barrier (BBB) is a major obstacle that drugs must overcome in order to reach tumor cells. The role of this barrier is to transport essential nutrients while protecting and regulating the internal environment. Nanoparticles have been shown to transport drugs through this barrier and accumulate in tumor cells. This is significant since nanoparticles are drug carriers allowing chemotherapeutic drugs to accumulate in target areas (Sun et al., 2017). This is possible because they are able to be …


Pharmacologic Profiling Of Novel Compounds Via Fluorometric Analyses Of Monoamine Transporter Responses, Ashkhan Hojati Jan 2019

Pharmacologic Profiling Of Novel Compounds Via Fluorometric Analyses Of Monoamine Transporter Responses, Ashkhan Hojati

Theses and Dissertations

In humans and other organisms, monoaminergic systems are crucial in neuronal function and behavior. The monoamine transporters (MATs), which can be found on the presynaptic plasma membrane of neurons in the central nervous system (CNS), are crucial in the regulation of neurotransmitter concentration in the synaptic cleft. As the duration and concentration of neurotransmitters in the cleft affect further downstream signaling responses, these proteins are important targets for both understanding neuronal physiology and compounds of interest. Multiple theories exist proponing the contribution of MATs to a variety of mental and neurological disorders, including depression. This theory establishes that depression is …

Études primaires

In-ear devices are used in a wide range of applications for which the device's usability and/or efficiency is strongly related to comfort aspects that are influenced by the mechanical interaction between the device and the walls of the earcanal. Although the displacement of the earcanal walls due to the insertion of the device is an important characteristic of this interaction, existing studies on this subject are very limited. This paper proposes a method to estimate this displacement in vivo using a registration technique on magnetic resonance images. The amplitude, the location and the direction of the earcanal wall displacement are …

Clinician-Administered Versus Self-Administered Suboccipital Release On Superficial Backline Function, Colin Wilhite, Kristin A. Paloncy, Karen Rawkowski, Todd Daniel

Clinical Practice in Athletic Training

The effectiveness of trigger point release in the suboccipital region to improve hamstring mobility has been established in the literature, but the research has not clarified whether self-administered soft tissue techniques produce the same improvements to mobility as when the clinician delivers the manual trigger point release. The purpose of the study was to assess whether the same increase in hamstring mobility within the superficial backline function that is achieved with a clinician-administered suboccipital trigger point release can also be obtained through a patient/self-administered method. The study employed a randomized, descriptive laboratory design in which 60 participants reported for a …

A 23-year-old male Division I distance runner presented with several years of exertional stridor (high-pitched inspiratory noise caused by airflow obstruction), previously diagnosed as exercised-induced laryngeal obstruction (EILO), a condition formerly known as vocal cord dysfunction and exercised-induced paradoxical vocal fold motion. Over the course of roughly 3 years, the patient had previously failed conventional and invasive respiratory therapies for EILO including respiratory retraining, inspiratory muscle training, reflux suppression, allergy suppression, amitriptyline, performance psychology, and injection of botulinum toxin to the larynx. At a referral center that specializes in the treatment of EILO, the patient's diagnosis was confirmed through the …


Illumination Of The Golgi Apparatus Of Pathogenic And Nonpathogenic Naegleria Species, Tyler M. Poe Jan 2019

Illumination Of The Golgi Apparatus Of Pathogenic And Nonpathogenic Naegleria Species, Tyler M. Poe

Theses and Dissertations

In this study, Naegleria fowleri, a pathogenic amoeba and the causative agent of Primary Amebic Meningoencephalitis (PAM), was utilized to determine the presence or absence of classically conserved Golgi molecules featured in the expression of a Golgi apparatus. Previous studies concluded no Golgi expression via light microscopy and transmission electron microscopy, but a recent report on Naegleria gruberi indicated the presence of dispersed Golgi tubules. Non-pathogenic species of the Naegleria genus such as Naegleria gruberi 30540 and Naegleria lovaniensis 30569 were utilized in Western immunoblot analysis compared to reduced whole-cell lysate proteins of two strains of N. fowleri and …

Treatment Of Scapular Dyskinesis With Reflexive Neuromuscular Stimulation: A Case Report, Alli Z. Powell, Russell T. Baker Jan 2019

Treatment Of Scapular Dyskinesis With Reflexive Neuromuscular Stimulation: A Case Report, Alli Z. Powell, Russell T. Baker

Clinical Practice in Athletic Training

Scapular dyskinesis is an abnormal movement of the scapula due to poor motor control of the surrounding musculature and can lead to other glenohumeral pathologies. The pathology results in the lateral tilting of the scapula during many glenohumeral joint movements and weight-bearing activities of the upper extremity (i.e., plank). The typical conservative treatment protocol focuses on strengthening surrounding musculature and is often a lengthy protocol. A weakness of strengthening protocols is the failure to address the motor function of targeted muscles at the level of the central nervous system (CNS) to restore dynamic stability and motor control. Reactive Neuromuscular Stabilization …
