Kiaa1549-Braf Expression Establishes A Permissive Tumor Microenvironment Through Nfκb-Mediated Ccl2 Production, Ran Chen, Chanel Keoni, Christopher A. Waker, Robert M. Lober, Robert M. Lober, Yihsien Chen, David H. Gutmann

Pediatrics Faculty Publications

KIAA1549-BRAF is the most frequently identified genetic mutation in sporadic pilocytic astrocytoma (PA), creating a fusion BRAF (f-BRAF) protein with increased BRAF activity. Fusion-BRAF-expressing neural stem cells (NSCs) exhibit increased cell growth and can generate glioma-like lesions following injection into the cerebella of naïve mice. Increased Iba1+ monocyte (microglia) infiltration is associated with murine f-BRAF-expressing NSC-induced glioma-like lesion formation, suggesting that f-BRAF-expressing NSCs attract microglia to establish a microenvironment supportive of tumorigenesis. Herein, we identify Ccl2 as the chemokine produced by f-BRAF-expressing NSCs, which is critical for creating a permissive stroma for gliomagenesis. In addition, f-BRAF regulation of Ccl2 production …

Consent For Emergency Treatment: Emergency Department Patient Recall And Understanding, Ashley Lafountain

Scholarship in Medicine - All Papers

Informed consent is an important ethical and legal requirement that underlies the concept of patient autonomy. This prospective survey study was conducted to assess patient recall and understanding of consent for treatment in adult emergency department (ED) patients at an urban level 1 trauma center with annual volume of 95,000, Miami Valley Hospital. Out of a total 293 patients, most individuals reported only receiving a verbal explanation of the consent document (45%) or not reading the document at all (36%). About half of the patients recalled consenting to treatment (N=144, 49%) and over one third of patients could not recall …

Health Literacy: Approach To Colon Cancer In African Americans, Judith Jefferson-Gordon

Doctor of Nursing Practice Program Projects

Health literacy is vitally important for African-Americans (AA), with higher incidence and mortality rates of colon cancer compared to Caucasians nationally and in Ohio. Larrabee's Model for Change to EBP and Self -Efficacy Middle range nursing theory guided this DNP project. A retrospective chart review of AA patients with colon cancer was completed to determine types of teaching methods used by nurses during the clinical encounter. A convenience sample (8%) of AA patients received colon cancer care in the ambulatory setting at the healthcare facility in the Midwest. More than half were female and the remainder were male (65% vs. …

New Functions For The Proprioceptive System In Skeletal Biology, Ronen Blecher, Lia Heinemann-Yerushalmi, Eran Assaraf, Nitzan Konstantin, Jens R. Chapman, Timothy C. Cope, Guy S. Bewick, Robert W. Banks, Elazar Zelzer

Neuroscience, Cell Biology & Physiology Faculty Publications

Muscle spindles and Golgi tendon organs (GTOs) are two types of sensory receptors that respond to changes in length or tension of skeletal muscles. These mechanosensors have long been known to participate in both proprioception and stretch reflex. Here, we present recent findings implicating these organs in maintenance of spine alignment as well as in realignment of fractured bones. These discoveries have been made in several mouse lines lacking functional mechanosensors in part or completely. In both studies, the absence of functional spindles and GTOs produced a more severe phenotype than that of spindles alone. Interestingly, the spinal curve phenotype, …

Travers, Ulas Sunar

Dermatology Faculty Publications

Ultraviolet light exposure is the major cause for photodamage. Pathologic effects of UVradiation include precancerous actinic keratosis which can progress into squamous cellcarcinoma. UV exposures commonly encountered include sunlight and indoor tanning bedexposure. Actinic neoplasia (precancerous actinic keratosis and non-melanoma skincancer) are highly prevalent in elderly patients with fair skin, and those with lower immunesystems. The impact on our healthcare system is substantial, as currently the averageannual cost to treat non-melanoma skin cancer is 5 billion dollars [1]. Though often asource of considerable morbidity due to extensive surgical procedures to remove the skincancers in the normal populations, squamous cell carcinomas …

Trpv4 Mediates Hypotonic Inhibition Of Central Osmosensory Neurons Via Taurine Gliotransmission, Sorana Ciura, Masha Prager-Khoutorsky, Zahra S. Thirouin, Joshua C. Wyrosdic, James E. Olson, Wolfgang Liedtke, Charles W. Bourque

Emergency Medicine Faculty Publications

The maintenance of hydromineral homeostasis requires bidirectional detection of changes in extracellular fluid osmolality by primary osmosensory neurons (ONs) in the organum vasculosum laminae terminalis (OVLT). Hypertonicity excites ONs in part through the mechanical activation of a variant transient receptor potential vanilloid-1 channel (dn-Trpv1). However, the mechanism by which local hypotonicity inhibits ONs in the OVLT remains unknown. Here, we show that hypotonicity can reduce the basal activity of dn-Trpv1 channels and hyperpolarize acutely isolated ONs. Surprisingly, we found that mice lacking dn-Trpv1 maintain normal inhibitory responses to hypotonicity when tested in situ. In the intact setting, hypotonicity inhibits ONs …

Benzodiazepines I: Upping The Care On Downers: The Evidence Of Risks, Benefits And Alternatives, Jeffrey Guina, Brian Merrill

Psychiatry Faculty Publications

Benzodiazepines are some of the most commonly prescribed medications in the world. These sedative-hypnotics can provide rapid relief for symptoms like anxiety and insomnia, but are also linked to a variety of adverse effects (whether used long-term, short-term, or as needed). Many patients take benzodiazepines long-term without ever receiving evidence-based first-line treatments (e.g., psychotherapy, relaxation techniques, sleep hygiene education, serotonergic agents). This review discusses the risks and benefits of, and alternatives to benzodiazepines. We discuss evidence-based indications and contraindications, and the theoretical biopsychosocial bases for effectiveness, ineffectiveness and harm. Potential adverse effects and drug-drug interactions are summarized. Finally, both fast-acting/acute …

Preclinical Pharmacokinetic Evaluation To Facilitate Repurposing Of Tyrosine Kinase Inhibitors Nilotinib And Imatinib As Antiviral Agents, Hari Krishna Ananthula, Scott Parker, Erin Touchette, R. Mark Buller, Gopi Patel, Daniel Kalman, Johanna S. Salzer, Nadia Gallardo-Romero, Victoria Olson, Inger K. Damon, Tessa Moir-Savitz, Larry Sallans, Milton H. Werner, Catherine M.T. Sherwin, Pankaj B. Dasai

Pediatrics Faculty Publications

Background

Several tyrosine kinase inhibitors (TKIs) developed as anti-cancer drugs, also have anti-viral activity due to their ability to disrupt productive replication and dissemination in infected cells. Consequently, such drugs are attractive candidates for “repurposing” as anti-viral agents. However, clinical evaluation of therapeutics against infectious agents associated with high mortality, but low or infrequent incidence, is often unfeasible. The United States Food and Drug Administration formulated the “Animal Rule” to facilitate use of validated animal models for conducting anti-viral efficacy studies.

Methods

To enable such efficacy studies of two clinically approved TKIs, nilotinib, and imatinib, we first conducted comprehensive pharmacokinetic …

Benzodiazepines Ii: Waking Up On Sedatives: Providing Optimal Care When Inheriting Benzodiazepine Prescriptions In Transfer Patients, Jeffrey Guina, Brian Merrill

Psychiatry Faculty Publications

This review discusses risks, benefits, and alternatives in patients already taking benzodiazepines when care transfers to a new clinician. Prescribers have the decision—sometimes mutually agreed-upon and sometimes unilateral—to continue, discontinue, or change treatment. This decision should be made based on evidence-based indications (conditions and timeframes), comorbidities, potential drug-drug interactions, and evidence of adverse effects, misuse, abuse, dependence, or diversion. We discuss management tools involved in continuation (e.g., monitoring symptoms, laboratory testing, prescribing contracts, state prescription databases, stages of change) and discontinuation (e.g., tapering, psychotherapeutic interventions, education, handouts, reassurance, medications to assist with discontinuation, and alternative treatments).

Characterization Of Different Molecular Markers For Identification Of Salmonella Enterica Serovar Typhi In Pakistani Population, Faizan Muttiullah, Fida Muhammad Khan, Fakhar-I- Abbas, Sabiha Shamim

Journal of Bioresource Management

Typhoid is caused by Salmonella enterica serovar Typhi that is usually diagnosed by using serologic and immuno-chromatographic techniques in developing counties including Pakistan, which is thought to be an unreliable diagnostic method. For accurate diagnosis we used molecular techniques to amplify 204 bp StyR-36 and 498 bp flagellin gene for the identification of Salmonella enterica serovar Typhi. This study was done on 58 individuals diagnosed positive of typhoid via serologic tests and 50 healthy individuals as a control group. Success rate of amplification for flagellin gene was 77.58% while that for StyR-36 gene was 68.97% showing that flagellin gene primer …

Staged Reconstruction Of The Inferior Vena Cava After Gunshot Injury, Nathan M. Droz, John K. Bini, Kamran A. Jafree, John H. Matsuura

Department of Surgery Faculty Publications

A 23-year-old man with a gunshot injury to the abdomen and cardiac arrest requiring emergency department thoracotomy had a transection of the distal inferior vena cava (IVC) and small bowel injury. Because of persistent hemorrhagic shock, the IVC was ligated. During the next 3 days, he developed worsening bilateral leg edema. He was taken back for reanastomosis of his small bowel and reconstruction of the IVC using autologous femoral vein harvested from the right leg. We think that patients requiring ligation of the vena cava with worsening leg edema can benefit from a staged reconstruction of the IVC.
