Crimean-Congo Hemorrhagic Fever, Reuben Ninan Feb 2015

Crimean-Congo Hemorrhagic Fever, Reuben Ninan

Infectious Diseases Project 2015

The Crimean-Congo Hemorrhagic Fever (CCHF) is a tick-borne infectious viral disease in the family Bunyaviridae. The disease was first characterized in the Crimea in 1944 and given the name Crimean hemorrhagic fever. CCHF was then later recognized in 1969 as the cause of illness in the Congo, thus resulting in the current name of the disease. CCHF causes severe viral hemorrhagic fever outbreaks (CDC, 2014).


The Bubonic Plague, Matthew Morin, Ashton Westbrook Feb 2015

The Bubonic Plague, Matthew Morin, Ashton Westbrook

Infectious Diseases Project 2015

The bubonic plague is a very serious infectious disease caused by the bacterium Yersinia pestis. The plague is a zoonotic disease, which means it is usually transmitted to humans by animals. It is commonly transmitted through the bites of infected fleas or coming in direct contact with infected animal tissue (Schoenstadt, 2006). The bacterium can be found in fleas or small rodents such as chipmunks, squirrels, rats, or prairie dogs. The symptoms, including fever, chills, headache, and hemorrhages under the skin causing discoloration, are very harsh and unpleasant. This disease is infectious and extremely severe, and it is deadly if …


Typhoid Fever, Christian Nicholas Feb 2015

Typhoid Fever, Christian Nicholas

Infectious Diseases Project 2015

Typhoid fever is a waterborne disease. There are a reported 16 million illnesses and 600,000 deaths annually (Crump, 2010). Most cases occur in developing countries; however, citizens of developed countries who visit developing ones are at risk of catching this disease (CDC, 2013). The disease is caused by Salmonella typhi, which infects the lymph nodes, necessary for immune response. Basic symptoms include a prolonged fever, interruptions in proper bowel function (constipation and diarrhea), severe cough, and in some cases, rose-colored spots on the patient. Salmonella typhi is a gram-negative bacteria that can only be carried by humans. There is also …

Dengue Fever, Ashley Hernandez, Chris Harkness

Infectious Diseases Project 2015

In recent years, the transmission of dengue fever has increased surprisingly fast and has become a major international public health concern. As of today this disease has mainly affected large countries and has become a leading cause of hospitalization and death among children in the certain areas. The amount of people that have got this infection has dramatically increase in recent decades. Over 40% of the world’s population are currently at risk of getting Dengue Fever. There is now an estimate of 50-100 million people that catch this disease every year (World Health Organization, 2002).


A Look Into Tuberculosis, Adrian Vega, Brennan Heath Feb 2015

A Look Into Tuberculosis, Adrian Vega, Brennan Heath

Infectious Diseases Project 2015

Tuberculosis is a Mycobacterium which is a genus classified in the phylum Actinobacteria. This genus is known to cause diseases in mammals. Tuberculosis' scientific name is Mycobacterium tuberculosis. Robert Koch discovered pathogenic bacterial species discovered in 1882 by. M. tuberculosis has a waxy coating on the cell's surface which makes it unable to be Gram stained.(Brennan, 2003). Gram staining is a method to differentiate bacterial species into two groups. This bacterium is Gram-negative because the waxy coating will not absorb the stain. When M. tuberculosis is in the lungs it is engulfed by macrophages trying to eradicate the disease, but …

Ebola Hemorrhagic Fever (Ebolavirus), Katie Mckee, Maria Hernandez

Infectious Diseases Project 2015

Without treatment, the Ebola Virus (also known as hemorrhagic fever) has up to a 90% fatality rate. Understanding this disease could help save a person’s life, especially if that person has recently traveled to Africa.


Cholera Research Poster, James Sowards, Mac Duffield Feb 2015

Cholera Research Poster, James Sowards, Mac Duffield

Infectious Diseases Project 2015

Cholera kills 142,000 on average a year, each of these lives being equally important. In Haiti a huge outbreak of cholera occurred. So many people died it made the population unable to recover from such an epidemic. Cholera might not be as important to people that do not live near the area affected but it has changed the lives of many people around the world (WebMD LLC, 1994-2015).

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 …

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 …

Evaluating The Effects Of An Interdisciplinary Practice Model With Pharmacist Collaboration On Hiv Patient Co-Morbidities, Rebecca Cope, Leonard Berkowitz, Rebecca Arcebido, Jun-Yen Yeh, Nathan Trustman, Agnes Cha

Touro College of Pharmacy (New York) Publications and Research

Treatment of HIV now occurs largely within the primary care setting, and the principal focus of most visits has become the management of chronic disease states. The clinical pharmacist’s potential role in improving chronic disease outcomes for HIV patients is unknown. A retrospective cohort study was performed for HIV-positive patients also diagnosed with diabetes, hypertension, or hyperlipidemia. Characteristics and outcomes in 96 patients treated by an interdisciplinary team which included a clinical pharmacist (i.e., the intervention group) were compared to those in 50 patients treated by an individual healthcare provider (i.e., the control group). Primary outcomes were changes from baseline …

Customized Order-Entry Sets Can Prevent Antiretroviral Prescribing Errors: A Novel Opportunity For Antimicrobial Stewardship, Yi Guo, Philip Chung, Caryn Weiss, Keith Veltri, Grace Y. Minamoto

Touro College of Pharmacy (New York) Publications and Research

Background: Patients with human immunodeficiency virus (HIV) infection on antiretroviral (ARV) therapy are at increased risk for medication errors during transitions of care between the outpatient and inpatient settings. This can lead to treatment failure or toxicity. Previous studies have emphasized the prevalence of medication errors in such patients, but few have reported initiatives to prevent errors from occurring.

Methods: The study was conducted in a 1,400-bed health care center with a state-designated Acquired Immunodeficiency Syndrome (AIDS) Center in the Bronx, New York. The antimicrobial stewardship team and HIV specialists developed customized order-entry sets (COES) to guide ARV …

Majority Of Hiv/Hcv Patients Need To Switch Antiretroviral Therapy To Accommodate Direct Acting Antivirals, Rebecca Cope, Aaron Pickering, Thomas Glowa, Samantha Faulds, Peter Veldkamp, Ramakrishna Prasad

Touro College of Pharmacy (New York) Publications and Research

The impact of drug–drug interactions (DDIs) between interferon-free direct acting antiviral (DAA) regimens and antiretrovirals (ART) among HIV/HCV co-infected individuals in clinical practice settings is unknown. A singlecenter, retrospective chart review of co-infected patients was conducted from June 2014 to February 2015. Significant interactions between simeprevir (SMV), ledipasvir (LDV), and paritaprevir/ritonavir/ombitasvir plus dasabuvir (3D regimen) with ART were identified based on available literature. SMV had the largest number of DDIs and was further investigated to determine the feasibility of ART switch to allow for DAA use. Of 127 subjects, 23% had advanced liver disease; 86% of those with known HCV …

Treatment Outcomes For Infections Caused By “Spice” (S–Serratia, P–Pseudomonas Aeruginosa, I–Indole Positive Proteus, C–Citrobacter, E– Enterobacter) Organisms: Carbapenem Versus Non-Carbapenem Regimens, Stanley Moy, Roopali Sharma

Touro College of Pharmacy (New York) Publications and Research

Background. Techniques to identify AmpC β-lactamases in SPICE organisms are not yet optimized for the clinical laboratory and are not routinely done. Clinicians are often left with an uncertainty on the choice of antibiotic when a SPICE organism is isolated. The purpose of this study is to evaluate the outcomes of carbapenem versus non-carbapenem regimens in treating bacteremia or urinary tract infection (UTI) from a SPICE organism in a “real-world” setting.

Methods. This was a single-center, retrospective, case-cohort study consisting of adult patients who had clinical infection with a SPICE organism isolated from blood or urine cultures. Patients …

An Improved Method For Generating Axenic Entomopathogenic Nematodes., Shruti Yadav, Upasana Shokal, Steven Forst, Ioannis Eleftherianos

Microbiology, Immunology, and Tropical Medicine Faculty Publications

BACKGROUND: Steinernema carpocapsae are parasitic nematodes that invade and kill insects. The nematodes are mutualistically associated with the bacteria Xenorhabdus nematophila and together form an excellent model to study pathogen infection processes and host anti-nematode/antibacterial immune responses. To determine the contribution of S. carpocapsae and their associated X. nematophila to the successful infection of insects as well as to investigate the interaction of each mutualistic partner with the insect immune system, it is important to develop and establish robust methods for generating nematodes devoid of their bacteria.

FINDINGS: To produce S. carpocapsae nematodes without their associated X. nematophila bacteria, we …


Creutzfeldt-Jakob Disease And Alzheimer’S Disease: Does Overlap Of Mechanism Mean Overlap Of Treatment Methods?, David Rotblat Jan 2015

Creutzfeldt-Jakob Disease And Alzheimer’S Disease: Does Overlap Of Mechanism Mean Overlap Of Treatment Methods?, David Rotblat

The Science Journal of the Lander College of Arts and Sciences

Alzheimer’s disease is a neurodegenerative disorder that is the 6th leading cause of death in the United States. More than 5.5 million People over the age of 65 are currently diagnosed with Alzheimer’s disease with predictions of 13.8 million to be diagnosed by the year 2050 (Sultana, et al., 2013) (Hebert, Weuve, Scherr, & Evans, 2013). With few treatments available, scientists are desperately looking for a solution to this growing epidemic. Creutzfeldt-Jakob disease is also a neurodegenerative disorder, but with a far less prevalence of only 4.6 persons per million per year. It was discovered that Alzheimer’s and Creutzfeldt-Jakob disease …

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background. Schistosomiasis is a chronic disease caused by infection with parasitic worms of the genus Schistosoma. In sub-Saharan Africa, infections with S. haematobium are most common. Cystoscopic examination (CE) has been accepted as the gold-standard test for detecting the late manifestations of schistosomiasis, including urothelial cancer of the bladder. However, this procedure is invasive and 10 - 40% of tumours may remain undetected. A non-invasive examination and a new generation of biomarkers are needed for better monitoring of the disease.

Objective. To assess the usefulness of ultrasound (US) scans for monitoring of structural urinary tract disease by local public health …

Predictors Of Non-­Adherence To Medical Follow-­Up Care Among African Americans With Hiv/Aids, Phyllis D. Morgan, Cynthia B. Banks, Joshua Fogel

2010-2016 Archived Posters

Persons living with Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) who do not adhere to their medical follow-­ up appointments tend to have poorer health outcomes compared to HIV/AIDS patients who adhere to their medical follow-­up appointments (Lima et al., 2009). This study examined factors that influence non-­adherence of African-­Americans with HIV/AIDS to medical follow-­up appointments.


Multiplexed Loop-Mediated Isothermal Amplification Of The 16s Rrna Gene For The Diagnosis Of Neonatal Sepsis In Resource-Limited Environments, Griffin T. Sonaty Jan 2015

Multiplexed Loop-Mediated Isothermal Amplification Of The 16s Rrna Gene For The Diagnosis Of Neonatal Sepsis In Resource-Limited Environments, Griffin T. Sonaty

Inquiry: The University of Arkansas Undergraduate Research Journal

Sepsis, or dysregulated inflammation caused by bacterial infection, places a disproportionately high burden on newborns in developing countries. This is due in part to a lack of diagnostic tools suitable for sustainable use in resource-limited nurseries. One potential vehicle for a new diagnostic assay is loop-mediated isothermal amplification (LAMP), a high-yield DNA amplification method. LAMP has previously been used to detect genes from single species of bacteria in blood serum samples to aid in sepsis diagnosis. LAMP could be adapted to detect a broad set of bacteria, while retaining a degree of specificity that allows clinicians to begin directed antimicrobial …

Polio Eradication And Health Systems In Karachi: Vaccine Refusals In Context, Svea Closser, Rashid Jooma, Emma Varley, Naina Qayyum, Sonia Rodrigues, Akasha Sarwar, Patricia Omidian

Section of Neurosurgery

Community and health worker engagement will be key to polio eradication in Karachi, Pakistan. In this study, the authors conducted participant observation, interviews, and a document review in SITE Town, Karachi, an area that in recent years has harbored poliovirus. SITE’s diverse population includes large numbers of internally displaced persons who are disproportionately affected by polio and are more likely than other populations to refuse the polio vaccine. Vaccine acceptance and worker motivation in SITE Town were shaped by the discrepancy in funding and attention for polio eradication campaigns as compared with routine services. Parental vaccine refusals stemmed from a …

The Effect Of Optogenetic Manipulation Of Ss Interneurons Within Malformed, Epileptogenic Cortex, Nicole Ekanem Jan 2015

The Effect Of Optogenetic Manipulation Of Ss Interneurons Within Malformed, Epileptogenic Cortex, Nicole Ekanem

Theses and Dissertations

A large percentage of individuals with intractable epilepsies have an accompanying cortical malformation, the underlying cellular mechanisms of which are poorly understood. It is known however that in an animal model for one such malformation, polymicrogyria, epileptogenesis occurs most easily from an adjacent area termed the paramicrogyral region (PMR). Previous studies implicate SS interneurons as a potential contributor to this pathology, which lead to our hypothesis: in PMR, SS interneurons exert a higher modulatory influence on excitatory pyramidal cells, as compared to the same by SS interneurons within homologous control cortex.

Using a freeze-lesion model for polymicrogyria in transgenic mice …


Characterization Of A Novel Protease In Staphylococcus Aureus, Adam L. Johnson Jan 2015

Characterization Of A Novel Protease In Staphylococcus Aureus, Adam L. Johnson

Theses and Dissertations

A newly discovered cysteine protease, Prp, has been shown to perform an essential, site-specific cleavage of ribosomal protein L27 in Staphylococcus aureus. In Firmicutes and related bacteria, ribosomal protein L27 is encoded with a conserved N-terminal extension that must be removed to expose residues critical for ribosome function. Uncleavable and pre-cleaved variants were unable to complement an L27 deletion in S. aureus, indicating that this N-terminal processing event is essential and likely plays an important regulatory role. The gene encoding the responsible protease (prp) has been shown to be essential, and is found in all organisms …

The Genesis And Emergence Of Community-Associated Methicillin-Resistant Staphylococcus Aureus (Ca-Mrsa): An Example Of Evolution In Action?, Alan L. Gillen, Jason Conrad, Michael Cargill

Faculty Publications and Presentations

Staphylococcus aureus infections are a common cause of disease, particularly in colonized persons. Recently, a series of published articles have reported that community-acquired methicillin-resistant S. aureus (CA-MRSA) strains are evolving and increasingly becoming prevalent in households while health care acquired MRSA (HA-MRSA) is declining in the USA. The changing superbugs have often been used as an example of evolution in action. Although MRSA infections have become increasingly reported in the community, population-based studies of students preparing for the health professions having S. aureus and MRSA colonization are lacking. During the 2014–2015 school year 544 students were tested for MRSA carriage …
