Preparedness Of Nurses For Malignant Hyperthermia, Melissa Flemming

Nursing Student Class Projects (Formerly MSN)

Malignant hyperthermia (MH) is a potentially life threatening disorder that occurs following exposure to certain inhaled anesthetics such as halothane, isoflurane, sevoflurane, desflurane, enflurane, ether, and methoxyflurane alone or in combination with the depolarizing muscle relaxant, succinylcholine (Seifert,, Wahr, Pace, Cochrane, & Bagnola, 2014, p. 189). Patients experiencing malignant hyperthermia may progress to death if it is not recognized and treated early. Patient outcomes improve the earlier an intervention is given. Malignant hyperthermia is not a common condition and, therefore, nurses are frequently unfamiliar with the common signs, symptoms, and treatments. Malignant hyperthermia can occur in a variety of settings …

The Importance Of Evaluation And Management Of Sepsis, Severe Sepsis, And Septic Shock, Katherine Herda

Nursing Student Class Projects (Formerly MSN)

Sepsis is a life-threatening and complicated host response to the presence of infection that is affecting millions of individuals around the world each year (Dellinger et al., 2013, p. 583). According to Gray et al. (2013), sepsis is not only one of the primary causes of hospital admission but it is also a leading cause of morbidity and mortality worldwide (p. 397). Severe sepsis and septic shock are the more advanced and detrimental stages of sepsis, which are starting to increase in incidence and are killing one in four (and sometimes more) individuals infected (Dellinger et al., 2013, p. 583). …

Cationic Cell-Penetrating Peptides Are Potent Furin Inhibitors, Bruno Ramos-Molina, Adam N. Lick, Amir Nasrolahi Shirazi, Donghoon Oh, Rakesh Tiwari, Naglaa Salem El-Sayed, Keykavous Parang, Iris Lindberg

Pharmacy Faculty Articles and Research

Cationic cell-penetrating peptides have been widely used to enhance the intracellular delivery of various types of cargoes, such as drugs and proteins. These reagents are chemically similar to the multi-basic peptides that are known to be potent proprotein convertase inhibitors. Here, we report that both HIV-1 TAT47-57 peptide and the Chariot reagent are micromolar inhibitors of furin activity in vitro. In agreement, HIV-1 TAT47-57 reduced HT1080 cell migration, thought to be mediated by proprotein convertases, by 25%. In addition, cyclic polyarginine peptides containing hydrophobic moieties which have been previously used as transfection reagents also exhibited potent furin inhibition in vitro …

Connectivity Measures Are Robust Biomarkers Of Cortical Function And Plasticity After Stroke, Jennifer Wu, Erin Burke Quinlan, Lucy Dodakian, Alison Mckenzie, Nikhita Kathuria, Robert J. Zhou, Renee Augsburger, Jill See, Vu H. Lee, Ramesh Srinivasan, Steven C. Cramer

Physical Therapy Faculty Articles and Research

Valid biomarkers of motor system function after stroke could improve clinical decision-making. Electroencephalography-based measures are safe, inexpensive, and accessible in complex medical settings and so are attractive candidates. This study examined specific electroencephalography cortical connectivity measures as biomarkers by assessing their relationship with motor deficits across 28 days of intensive therapy. Resting-state connectivity measures were acquired four times using dense array (256 leads) electroencephalography in 12 hemiparetic patients (7.3 ± 4.0 months post-stroke, age 26–75 years, six male/six female) across 28 days of intensive therapy targeting arm motor deficits. Structural magnetic resonance imaging measured corticospinal tract injury and infarct volume. …

Tslp-Induced Mechanisms And Potential Therapies For Crlf2 B-Cell Acute Lymphoblastic Leukemia, Olivia L. Francis

Loma Linda University Electronic Theses, Dissertations & Projects

Childhood CRLF2 B-cell Acute Lymphoblastic Leukemia (CRLF2 B-ALL) is a high-risk form of leukemia that is associated with poor patient survival outcomes. CRLF2 B-ALL is five times more prevalent in Hispanic children than others and is associated with a higher rate of relapse, thus contributing significantly to childhood cancer health disparities. This disease occurs due to alterations of the CRLF2 gene, leading to overexpression of the CRLF2 protein- a component of the receptor signaling complex for the cytokine Thymic Stromal LymphoPoietin (TSLP) on the surface of B-ALL cells. TSLP has been shown to induce proliferation of human and mouse B-cell …

Diabetic Prevention The Hard Way: Modified Diet And Increased Exercise, Torrie Reese St.Julien

Doctor of Nursing Practice Final Manuscripts

Background and Purpose: In the United States, 79 million people are pre-diabetic: most have no symptoms. If left untreated, 37% will develop diabetes within 4 years. Fourteen percent of United States health care expenditures are related to diabetic complications. This Evidenced Based Project (EBP) involved a behavioral lifestyle change with the purpose of 7% weight loss and a minimum of 150 minutes of physical activity a week. It was also designed to reduce risk factors and glycated hemoglobin A1c (HgA1c) levels.

Methods: The interventional approach was modeled after the Diabetes Prevention Program (DPP) and Group Lifestyle Balance Program. Participants were …

Novel Advances In Alzheimer's Disease, Jacob P. Naumann

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Alzheimer’s disease, the most common form of dementia in adults, is a progressive degenerative neurological disease that affects memory, cognition, and behavior. Dr. Alois Alzheimer discovered and diagnosed the irreversible disease in 1906 after documenting the famous case of Auguste Deter.¹ Since the discovery of the disease, numerous advances have made it possible to not only better understand the causal factors, but also to improve the medical diagnosis and preventative measures that healthcare providers can implement. For the first time since 1984, the National Institute on Aging (NIAA) and the Alzheimer’s Association (AA) proposed and published new diagnostic guideline …

Functional Analysis Of The Molluscum Contagiosum Virus Mc160 Death Effector Domain-Containing Protein Rxdl Motif, Sarah Weber

Seton Hall University Dissertations and Theses (ETDs)

The Molluscum contagiosum virus (MCV) is a member of the Poxviridae family that causes benign skin lesions. MCV lesions persist on average for 8-12 months in otherwise healthy individuals. MCV lesions are characterized by reduced inflammation. The persistence and reduction of inflammation at the site of MCV lesions have been attributed to MCV immune evasion genes. MCV encodes two death effector domain (DED) containing proteins, MC159 and MC160. DEDs are found in cellular proteins such as FADD and procaspase-8. These cellular proteins are involved in several innate immune responses such as apoptosis and activation of interferon (IFN). Presumably, MC159 and …

A Novel Caspase 8 Selective Small Molecule Potentiates Trail-Induced Cell Death, Octavian Bucur, Gabriel Gaidos, Achani Yatawara, Bodvael Pennarun, Chamila Rupasinghe, Jérémie Roux, Stefan Andrei, Bingqian Guo, Alexandra Panaitiu, Maria Pellegrini, Dale Mierke, Roya Khosravi-Far

Dartmouth Scholarship

Recombinant soluble TRAIL and agonistic antibodies against TRAIL receptors (DR4 and DR5) are currently being created for clinical cancer therapy, due to their selective killing of cancer cells and high safety characteristics. However, resistance to TRAIL and other targeted therapies is an important issue facing current cancer research field. An attractive strategy to sensitize resistant malignancies to TRAIL-induced cell death is the design of small molecules that target and promote caspase 8 activation. For the first time, we describe the discovery and characterization of a small molecule that directly binds caspase 8 and enhances its activation when combined with TRAIL, …

Structural Studies Of The Ig58 Domain Of The Giant Muscle Protein Obscurin, Matthew C. Oehler

Senior Honors Projects, 2010-2019

Obscurin (720-900 kD) is a giant sarcomeric signaling protein that is the only known link

between the cytoskeleton and the surrounding membrane structure. Mutations to obscurin

and to obscurin binding partners have been linked to human muscle diseases such as

hypertrophic cardiomyopathies and muscular dystrophy. These diseases likely occur due

to the abrogation of specific molecular interactions necessary for suitable function. To

more fully understand how specific mutations lead to disease, here we solve the highresolution

structure of obscurin Ig58. The literature shows that an Arg8Gln mutation to

the Ig58 domain of obscurin is associated with hypertrophic cardiomyopathy (HCM).

Chemical …

Structural And Functional Interactions Between Bro1 Domain Of Human Alix Protein And Nucleocapsid Packaging Rna Complex From Hiv, Scott Gross

Graduate School of Biomedical Sciences Theses and Dissertations

A virus is only as powerful as its ability to spread. Enveloped retroviruses, namely HIV-1, use exocytosis pathways that normal host cells use to release particles from the plasma membrane. The main pathways of interest in this study are the Endosomal Sorting Complex Required for Transport (ESCRT) and adjacent ALIX pathways. The ESCRT pathway is especially important for degradation of receptor/cargo complexes that form Multi-Vesicular Bodies (MVBs). Currently, there is no known therapy that targets this endosomal pathway, which would prevent the spread of the virus to other cells. The virus has adapted to jump from pathway to pathway when …

Identification Of Transcription Factors Gzf3, Rfx1, Orf19.3928 As Being Implicated In Candida-Bacterial Interactions., Joni Watson

Undergraduate Honors Theses

Candida albicans is an opportunistic pathogen that is present in the normal flora in a majority of individuals. One key factor in C. albicans virulence is the ability to change its morphology from yeast to an elongated or hyphal form. The regulation of this morphogenesis relies in part upon quorum sensing (QS) molecules. C. albicans often exists as part of a mixed culture alongside other microbes and is influenced by their presence as well as the presence of QS molecules that they produce. In this study, a library of diploid homozygous transcriptional regulator knockout (TRKO) mutants were screened to identify …

Oseltamivir-Warfarin Interaction In Hypoplastic Left Heart Syndrome: Case Report And Review., Jonathan B. Wagner, Susan M. Abdel-Rahman

Manuscripts, Articles, Book Chapters and Other Papers

An 8-year-old boy with hypoplastic left heart syndrome with a previous history of thrombosis within the inferior vena cava receiving stable warfarin dosing for anticoagulation was diagnosed with influenza B. He was subsequently placed on oseltamivir therapy according to the Centers for Disease Control and Prevention clinical practice guidelines. During the hospitalization, his international normalized ratio steadily increased to supratherapeutic levels and returned to baseline after discontinuation of oseltamivir therapy. This case represents a drug-drug interaction that has not been previously reported in children or adolescents. An extensive review of the pharmacokinetic and pharmacodynamic literature did not uncover a definitive …

Src Homology 2 Domain-Containing 5’-Inositol Phosphatase-2 (Ship2) Is An Effector Of Lymphatic Dysfunction, Germaine D. Agollah

Dissertations and Theses (Open Access)

The lymphatic system is essential for the transport of excess fluid, protein, and foreign materials from interstitial tissues to lymph nodes; for immune surveillance, and to maintain fluid homeostasis. Dysregulated lymphatics can be attributed to pathological conditions including tumor metastasis, inflammation, chronic wounds, obesity, blood vascular disorders, and lymphedema. Of these, lymphedema is the most extreme of lymphatic disorders and is represented by a spectrum of symptoms ranging from mild, subtle presentation to severe, disfiguring, overt presentation. Lymphedema is more manageable in the early stages of disease but severely reduces quality of life with progression. Due to lack of molecular …

Role Of Ataxia Telangiectasia Mutated Kinase In The Healing Process Of The Heart Following Myocardial Infarction, Laura L. Daniel

Electronic Theses and Dissertations

Ataxia telangiectasia (AT), caused by mutations in the gene encoding ataxia telangiectasia mutated kinase (ATM), is a rare autosomal recessive disorder. AT individuals exhibit neuronal degeneration and are predisposed to cancer. Carriers of this disorder are predisposed to cancer and ischemic heart disease. Heart disease, mostly due to myocardial infarction (MI), is a leading cause of death in the US. Following MI, release of catecholamines in the heart stimulates β- adrenergic receptors (β-AR). Our lab has shown that β-AR stimulation increases ATM expression in the heart and myocytes, and ATM plays an important role in β-AR-stimulated myocardial remodeling with effects …

Site-Specific Immunomodulator: A Novel Treatment For Crohn's Disease, Brian Bressler, Kevin P. Bethel, Ralf Kleef, Sophie L. Reynolds, Simon Sutcliffe, David W. Mullins, Hal Gunn

Dartmouth Scholarship

We investigated the mechanism of action, safety, and efficacy of the Site-Specific Immunomodulator (SSI) QBECO, a novel immunotherapy for Crohn’s disease (CD). Using human monocytic THP-1 cells, we demonstrate that SSI QBECO (derived from the common colon bacteria E. coli) activates macrophages to an M1 phenotype (associated with enhanced capacity to eliminate bacteria and activate innate immune responses). We assessed SSI QBECO in a compassionate use protocol of ten adult patients with active CD. Patients with moderate to severe clinical symptoms receiving conventional CD treatments and/or complementary therapies were included, except patients receiving anti-TNF medications. SSI QBECO was self-administered subcutaneously …

Background

Intrahepatic cholangiocarcinoma (ICC) is a highly aggressive tumor of the bile duct, and a significant public health problem in East Asia, where it is associated with infection by the parasiteOpisthorchis viverrini. ICC is often detected at an advanced stage and with a poor prognosis, making a biomarker for early detection a priority.

Methods

We have comprehensively profiled miRNA expression levels in ICC tumor tissue using small RNA-Seq and validated these profiles using quantitative PCR on matched plasma samples.

Results

Distinct miRNA profiles were associated with increasing histological differentiation of ICC tumor tissue. We also observed that histologically …

The Plight Of The Lucluc: Examining The Deadly Mystery Of Nodding Syndrome, Ethan K. Mcgann

Senior Honors Theses

Nodding syndrome (NS) is an emerging epidemic neurological disease that is shrouded in mystery. It is currently only found in the post-conflict regions of South Sudan, northern Uganda, and Tanzania. NS occurs in children from the ages of five to fifteen and is characterized by a loss of motor control in the neck muscles. Seizure episodes can range in intensity from atonic to tonic-clonic, and the onset of the first episode generally marks the beginning of a decline in the child’s physical and mental health. NS is a progressive disease that generally results in physical wasting, stunted growth, behavioral difficulties, …

The Therapeutic Role Of Turmeric In Treatment And Prevention Of Alzheimer’S Disease, Rylan M. Mcquade

Selected Honors Theses

As a devastating neurological condition that expends millions of lives each year, Alzheimer’s disease (AD) is a subject of intense investigation.¹ Although AD has been known for over a century, the precise mechanisms that underlie AD pathogenesis and development are still poorly understood. The Alzheimer phenotype is typified by extracellular amyloid-beta (Aβ) plaques and intracellular neurofibrillary tangles (NFTs), causing researchers to notice several key enzymes implicated in this process.¹ Most notable are β and γ secretases (which drive Aβ plaque production) and phospholipase

A₂ (which stimulates major cascade activation through the specific cleavage of fatty acyl esters). …

Guidelines For Pre-Clinical Assessment Of The Acetylcholine Receptor-Specific Passive Transfer Myasthenia Gravis Model - Recommendations For Methods And Experimental Designs., Linda L. Kusner, Mario Losen, Angela Vincent, Jon Lindstrom, Socrates Tzartos, Konstantinos Lazaridis, Pilar Martinez-Martinez

Pharmacology and Physiology Faculty Publications

Antibodies against the muscle acetylcholine receptor (AChR) are the most common cause of myasthenia gravis (MG). Passive transfer of AChR antibodies from MG patients into animals reproduces key features of human disease, including antigenic modulation of the AChR, complement-mediated damage of the neuromuscular junction, and muscle weakness. Similarly, AChR antibodies generated by active immunization in experimental autoimmune MG models can subsequently be passively transferred to other animals and induce weakness. The passive transfer model is useful to test therapeutic strategies aimed at the effector mechanism of the autoantibodies. Here we summarize published and unpublished experience using the AChR passive transfer …

Anti-Tumoral Effects Of Mir-3189-3p In Glioblastoma, Duane Jeansonne, Mariacristina Deluca, Luis Marrero, Adam Lassak, Marco Pacifici, Dorota Wyczechowska, Anna Wilk, Krzysztof Reiss, Francesca Peruzzi

School of Medicine Faculty Publications

Glioblastoma is one of the most aggressive brain tumors. We have previously found up-regulation of growth differentiation factor 15 (GDF15) in glioblastoma cells treated with the anticancer agent fenofibrate. Sequence analysis of GDF15 revealed the presence of a microRNA, miR-3189, in the single intron. We then asked whether miR-3189 was expressed in clinical samples and whether it was functional in glioblastoma cells. We found that expression of miR-3189-3p was down-regulated in astrocytoma and glioblastoma clinical samples compared with control brain tissue. In vitro, the functionality of miR-3189-3p was tested by RNA-binding protein immunoprecipitation, and miR-3189-3p coimmunoprecipitated with Argonaute 2 together …

Association Between Body Surface Area And Outcomes After Percutaneous Coronary Intervention, Kambiz Shetabi, Tonga Nfor, Fengyi Shen, Anjan Gupta, Tanvir Bajwa, Suhail Allaqaband

Journal of Patient-Centered Research and Reviews

Purpose

Obesity is a well-known risk factor for adverse cardiovascular events, but some studies suggest higher body mass index (BMI) is associated with better outcomes after ST-segment elevation myocardial infarction (STEMI). We sought to determine the effect of body surface area (BSA) on adverse events after primary percutaneous coronary intervention (PCI) for STEMI and how this relates to the reported obesity paradox theory.

Methods

We analyzed a prospective registry of patients with STEMI who underwent primary PCI at a tertiary care hospital from 2003 to 2009. Post-PCI complications and 1-year all-cause mortality were compared across BSA quartiles. Relationship with 1-year …

The Cell's Antenna And Bending With The Flow, Surya M. Nauli, Kimberly F. Atkinson, Sarmed H. Kathem

Pharmacy Faculty Articles and Research

Polycystic kidney disease (PKD) is the most common life-threatening genetic disease worldwide – affecting about 12.5 million people. Patients with the condition have multiple fluid-filled cysts in their kidneys that lead to a massive enlargement of the organ and gradual worsening of its function, as well as complete failure in many cases. The lack of available treatment means patients may eventually require regular dialysis or a kidney transplant.

Two Potential Hookworm Daf-16 Target Genes, Snr-3 And Lpp-1: Gene Structure, Expression Profile, And Implications Of A Cis-Regulatory Element In The Regulation Of Gene Expression, Xin Gao, Kevin Goggin, Camille Dowling, Jason Qian, John Hawdon

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Hookworms infect nearly 700 million people, causing anemia and developmental stunting in heavy infections. Little is known about the genomic structure or gene regulation in hookworms, although recent publication of draft genome assemblies has allowed the first investigations of these topics to be undertaken. The transcription factor DAF-16 mediates multiple developmental pathways in the free living nematode Caenorhabditis elegans, and is involved in the recovery from the developmentally arrested L3 in hookworms. Identification of downstream targets of DAF-16 will provide a better understanding of the molecular mechanism of hookworm infection.

Methods

Genomic Fragment 2.23 containing a DAF-16 binding …

Systems Level Analysis Of Systemic Sclerosis Shows A Network Of Immune And Profibrotic Pathways Connected With Genetic Polymorphisms, J. Matthew Mahoney, Jaclyn Taroni, Viktor Martyanov, Tammara A. A. Wood, Casey S. Greene, Patricia A. Pioli, Monique E. Hinchcliff, Michael L. Whitfield

Dartmouth Scholarship

Systemic sclerosis (SSc) is a rare systemic autoimmune disease characterized by skin and organ fibrosis. The pathogenesis of SSc and its progression are poorly understood. The SSc intrinsic gene expression subsets (inflammatory, fibroproliferative, normal-like, and limited) are observed in multiple clinical cohorts of patients with SSc. Analysis of longitudinal skin biopsies suggests that a patient's subset assignment is stable over 6-12 months. Genetically, SSc is multi-factorial with many genetic risk loci for SSc generally and for specific clinical manifestations. Here we identify the genes consistently associated with the intrinsic subsets across three independent cohorts, show the relationship between these genes …
