Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

Doctor of Nursing Practice

The purpose of this quality improvement project was to increase human papillomavirus vaccination series initiation rates among indigent women, ages 19-26, at a clinic in South Texas. The human papillomavirus is a sexually transmitted infection that has been associated with multiple types of cancers. Each year, approximately 6.2 million cases of the human papillomavirus infection are diagnosed; as many as 75% of all new infections occur among females 18-26 years of age. The human papillomavirus vaccination has a high efficacy in regards to cancer prevention, preventing as many as 76% of cancers with only one dose. The project included educating …

Behavioral Ecology And Associated Virology Of Mosquito-Host Interactions In Southern California, Oliver Eshun

Loma Linda University Electronic Theses, Dissertations & Projects

Elucidating characteristics of mosquito-host interactions are critical for understanding the ecology and epidemiology of mosquito-borne diseases. In this dissertation, I conducted three studies to explore potential mosquito-host interactions and associated virus infection rates. I first demonstrated that mosquito captures at CO2-baited traps decreased most markedly with height above ground, and also decreased with distance from water at a riparian area but not at an open water source lacking a vegetated border. Birds might therefore prefer elevated nests or roosts to avoid mosquitoes. The second study examined the anti-mosquito behaviors of budgerigars (Melopsittacus undulatus) in a laboratory study. The birds defended …

Pneumonia Vaccines: Current Recommendations And Advocacy Opportunities, Laressa Bethishou

Pharmacy Faculty Articles and Research

"Despite the demonstrated efficacy of these vaccines, only 66.9% of adults over age 65 years have ever received a pneumonia vaccine. Given the consequences of acquiring pneumonia, there is both a need and an opportunity to improve vaccination rates. The pharmacist can play a valuable role in identifying high-risk patients, providing education on benefits and risks, and advocating for pneumonia vaccination when indicated."

A Mirna Signature For Cognitive Deficits And Alcohol Use Disorder In Persons Living With Hiv/Aids, Dorota Wyczechowska, Hui-Yi Lin, Andrea Laplante, Duane Jeansonne, Adam Lassak, Christopher H. Parsons, Patricia E. Molina, Francesca Peruzzi

School of Medicine Faculty Publications

HIV-associated neurocognitive disorders (HAND) affects more than half of persons living with HIV-1/AIDS (PLWHA). Identification of biomarkers representing the cognitive status of PLWHA is a critical step for implementation of successful cognitive, behavioral and pharmacological strategies to prevent onset and progression of HAND. However, the presence of co-morbidity factors in PLWHA, the most common being substance abuse, can prevent the identification of such biomarkers. We have optimized a protocol to profile plasma miRNAs using quantitative RT-qPCR and found a miRNA signature with very good discriminatory ability to distinguish PLWHA with cognitive impairment from those without cognitive impairment. Here, we have …

Six-Year Experience Of Influenza Vaccination As A Condition Of Employment For A Large Regional Health Care System, John R. Brill, Mark Hermanoff, Angela Tonozzi, Mary Jo Capodice, Jennifer Farrar, Zarina Dawoodbhai

Journal of Patient-Centered Research and Reviews

Background: Influenza remains a significant contributor to morbidity and mortality in the United States. Health care workers (HCW) can be both victims and vectors of influenza. Influenza vaccination of HCW is protective for both caregivers and patients, but voluntary programs generally fail to achieve rates recommended by the Centers for Disease Control and Prevention. Despite a complex, multifaceted influenza program initiated in 1996 that included significant education and promotion as well as free on-site vaccination, annual Aurora Health Care caregiver immunization rates remained in the mid-70s until adoption of a “condition of employment” strategy in 2011.

Purpose: Discuss the annual …

Intrinsic And Innate Defenses Of Neurons: Détente With The Herpesviruses, Lynn Enquist, David A. Leib

Dartmouth Scholarship

Neuroinvasive herpesviruses have evolved to efficiently infect and establish latency in neurons. The nervous system has limited capability to regenerate, so immune responses therein are carefully regulated to be nondestructive, with dependence on atypical intrinsic and innate defenses. In this article we review studies of some of these noncanonical defense pathways and how herpesvirus gene products counter them, highlighting the contributions that primary neuronal in vitro models have made to our understanding of this field.

Furmanek, Conner English, Mary Bishop, Cathy Spencer, Daniel Truelove, Julio A. Ramirez, Anupama Raghuram, Paula Peyrani

Faculty and Staff Scholarship

Background

Controversy still exists regarding gender differences in virologic response between treatment-na•ve HIV-infected individuals. The objective of this study was to evaluate gender difference in virologic and immunologic response to antiretroviral therapy in treatment-na•ve HIV-infected individuals. Methods

This was a retrospective, observational study of treatment-na•ve HIV-infected individuals managed at the 550 clinic who started antiretroviral therapy (ART) between January 1st, 2010 and December 31, 2015. Patients with available viral load and CD4 counts before and one year after initiating ART were included in this study. Virologic suppression was defined as < 48 HIV-1 RNA copies/mL, and mmunologic recovery was defined as a CD4 count increase of at least 150 cells/mm3. Dichotomous variables were reported in number and percentages and analyzed using Chi-squared tests and Fisher’s exact (whichever was appropriate). Continuous variables were reported as median and interquartile range (IQR) and analyzed using Wilcox rank-sum tests. Multivariate analyses performed were logistic regressions with adjustment for other covariates. P value <0.05 was considered statistically significant. R version 3.3.2 was used for the statistical analysis. Results

A total of 70 women and 90 men were included …

Natural History Of Hpv Infection Across The Lifespan: Role Of Viral Latency., Patti E Gravitt, Rachel L Winer

Global Health Faculty Publications

Large-scale epidemiologic studies have been invaluable for elaboration of the causal relationship between persistent detection of genital human papillomavirus (HPV) infection and the development of invasive cervical cancer. However, these studies provide limited data to adequately inform models of the individual-level natural history of HPV infection over the course of a lifetime, and particularly ignore the biological distinction between HPV-negative tests and lack of infection (i.e., the possibility of latent, undetectable HPV infection). Using data from more recent epidemiological studies, this review proposes an alternative model of the natural history of genital HPV across the life span. We argue that …

Cross-Reactive Immunity To Porcine Reproductive And Respiratory Syndrome Virus And Its Contribution To Protection, Ignacio Correas

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Due to the vast geographical distribution and significant economic losses generated, porcine reproductive and respiratory syndrome virus (PRRSV) can be considered the most important swine pathogen of contemporary times. Current control and eradication strategies against PRRSV have difficulty succeeding because of their complex nature and the absence of an effective vaccine. A major obstacle for PRRSV vaccine development is the broad heterogeneity of the virus, both at the genetic and antigenic level, its rapid evolution, and an incomplete knowledge of the immune responses responsible for clearing the virus from the host. Specifically, how known correlates of protection against PRRSV—neutralizing antibodies …

Anti-Herv-K (Hml-2) Capsid Antibody Responses In Hiv Elite Controllers., Miguel De Mulder, Devi Sengupta, Steven G Deeks, Jeffrey N Martin, Christopher D Pilcher, Frederick M Hecht, Jonah B Sacha, Douglas F Nixon, Henri-Alexandre Michaud

Microbiology, Immunology, and Tropical Medicine Faculty Publications

Background

Human endogenous retroviruses (HERVs) comprise approximately 8% of the human genome and while the majority are transcriptionally silent, the most recently integrated HERV, HERV-K (HML-2), remains active. During HIV infection, HERV-K (HML-2) specific mRNA transcripts and viral proteins can be detected. In this study, we aimed to understand the antibody response against HERV-K (HML-2) Gag in the context of HIV-1 infection.

Results

We developed an ELISA assay using either recombinant protein or 164 redundant “15mer” HERV-K (HML-2) Gag peptides to test sera for antibody reactivity. We identified a total of eight potential HERV-K (HML-2) Gag immunogenic domains: two on …

A Roundtable On Cross-Sector Collaboration And Resource Alignment For Health Equity: Meeting Summary, Onyemaechi Nweke

Journal of Health Disparities Research and Practice

Cross-sector collaboration is a highly recommended strategy to eliminate health inequities nationally and globally. In the federal sector, it is evolving into an important approach for solving complex social problems, as evidenced by its steady proliferation the past few decades. Despite the increased adoption of cross-sector collaboration, it is still not a default strategy or preeminent option for managing complex social problems. In September 2015, the Federal Interagency Health Equity Team (FIHET) hosted a Roundtable event to discuss opportunities and strategies to foster widespread adoption of cross-sector collaboration and resource alignment. The Roundtable featured several expert panelists and participants from …

Journal of Health Disparities Research and Practice

Background: Chronic diseases are an important contributor to morbidity and mortality among racial/ethnic minority, low-income, and other under-resourced populations. Given that state health departments (and their chronic disease programs) play a significant role in providing population and preventive health services, their capacity to promote health equity is an important consideration in national efforts to address chronic diseases. The purpose of this study was to examine capacity needs of state chronic disease programs with respect to promoting health equity.

Methods: In 2015, the National Association of Chronic Disease Directors (NACDD) conducted a survey of its members that work within a …

Achieving Health Equity For Indian Country, Jamie Ishcomer

Journal of Health Disparities Research and Practice

The essence of health equity is giving resources where they are needed most. American Indians and Alaska Natives (AI/AN) continue to have the worst health outcomes, live in some of the most desperate of conditions, and lack access to even basic amenities that many other Americans could not survive without. Although Tribes have been plagued with social, economic and political injustice for centuries, there is an opportunity to put a stop to the systematic oppression and build up the first peoples of this country. A partnership between the National Indian Health Board (NIHB) and the National Partnership for Action to …

Rhode Island’S Health Equity Zones: Addressing Local Problems With Local Solutions, Nicole Alexander-Scott, Md, Mph, Ana P. Novais, Ma, Carol Hall-Walker, Mpa, Angela B. Ankoma, Mph, Msw, John P. Fulton, Phd

Journal of Health Disparities Research and Practice

The Rhode Island Department of Health (RIDOH) describes the strategies and infrastructure it has developed to fund its placed-based initiatives to address the social determinants of health to eliminate health disparities. Using a data driven and community-led approach, RIDOH funded 10 local collaboratives, each with its own, geographically-defined “Health Equity Zone,” or “HEZ,” and, to support the collaboratives, created a new “Health Equity Institute,” a “HEZ Team” of 9 seasoned project managers, and direct lines of communications between these assets and the Office of the Director of Health.

Journal of Health Disparities Research and Practice

In April 2011, the U.S. Department of Health and Human Services’ (HHS) Office of Minority Health (OMH) launched the National Partnership for Action to End Health Disparities (NPA) to increase the effectiveness of efforts to eliminate health disparities by coordinating partners, leaders, and stakeholders committed to action. At its core, the NPA is an experiment in collaboration that relies heavily on those on the front line who are actively engaged in minority health work at multiple levels. It gives them the responsibility of identifying and helping to define core actions, new approaches, and new partnerships that ultimately will help to …

The Guide To Community Preventive Services Review Of Interventions To Promote Health Equity In The United States, Robert Hahn, Jonathan E. Fielding, M.D., M.P.H., M.A., M.B.A, Robert L. Johnson, M.D., Carles Muntaner, M.D., Ph.D., M.H.S., Benedict I. Truman, M.D., M.P.H., Tracy Orleans

Journal of Health Disparities Research and Practice

The optimal approach to eliminating health inequities is through evidence-based interventions. In 2009, the non-federal Community Preventive Services Task Force launched a series of systematic reviews of interventions to promote health equity. Topics to be considered include education, employment, housing, and transportation. Thus far, reviews have focused on educational interventions: center-based early childhood education, full-day kindergarten programs, out-of-school time academic programs, high school completion programs, and school-based health centers. These reviews demonstrate the benefits of diverse educational interventions in advancing health equity. Here, we summarize the strategy of Community Guide health equity reviews, first findings and challenges.

Extrafollicular Activities: Perspectives On Hiv Infection, Germinal Centerindependent Maturation Pathways, And Kshv-Mediated Lymphoproliferation, Jennifer Totonchy

Pharmacy Faculty Articles and Research

Early events in the pathogenesis of KSHV-associated lymphoproliferations in the context of HIV disease remain poorly understood. Recent research indicates that latent HIV infection causes persistent immune dysfunction in B cell follicles. Simultaneously, lack of T cell immune surveillance in the lymph nodes dysregulates the biology of EBV. In sum, these defects bias B lymphocyte maturation away from traditional T cell-dependent germinal center-mediated pathways and towards extrafollicular pathways. Recent advances in B lymphocyte immunology suggest that extrafollicular maturation pathways for antibody secreting cells are more flexible and robust than previously believed. These responses are now understood to be both durable …

Finding Human Proteins That Bind To A Lassa Virus Protein, Maria Alejandra Pardo Ruge, Veronica J. Heintz, Douglas J. Lacount

The Summer Undergraduate Research Fellowship (SURF) Symposium

Viral hemorrhagic fevers are severe illnesses caused by many different viruses. Lassa Virus is one of these important pathogens in Western Africa, causing hemorrhagic fever and eventually death without early medical treatment. There is no vaccine and there is little information on host-pathogen interactions. Therefore, the interaction between viral proteins and host targets is useful to understand Lassa virus’s lifecycle and pathology, and to develop ways to prevent infection. In this project, we study the nucleoprotein of Lassa virus (NP), which has been reported to have anti-interferon (IFN) activity through elimination of double stranded RNA (dsRNA). These features could be …

Molecular Mechanisms Of Dna Replication Initiation In Hpvs With Genetic Variations Leading To Cellular Carcinogenesis, Gulden Yilmaz

Graduate School of Biomedical Sciences Theses and Dissertations

Human papillomaviruses are a vast family of double-stranded DNA viruses containing non-carcinogenic and carcinogenic types, whose crucial differences remain unknown, except for the difference in the frequency of DNA replication. The human papillomavirus (HPV) E2 protein regulates the initiation of viral DNA replication and transcription. Its recognition and binding to four 12 bp palindromic sequences in the viral origin is essential for its function. Little is known about the DNA binding mechanism of the E2 protein found in HPV types that have low risk for oncogenicity (low-risk) as well as the roles of various elements of the individual binding sites. …

Zika virus (ZIKV) remained largely quiescent for nearly six decades after its first appearance in 1947. ZIKV reappeared after 2007, resulting in a declaration of an international “public health emergency” in 2016 by the World Health Organization (WHO). Until this time, ZIKV was considered to induce only mild illness, but it has now been established as the cause of severe clinical manifestations, including fetal anomalies, neurological problems, and autoimmune disorders. Infection during pregnancy can cause congenital brain abnormalities, including microcephaly and neurological degeneration, and in other cases, Guillain-Barré syndrome, making infections with ZIKV a substantial public health concern. Genomic and …

Comparison Of Chikungunya Virus Strains In Disease Severity And Susceptibility To T-705 (Favipiravir), In Vitro And In Vivo, Makda Gebre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chikungunya is a mosquito-transmitted disease caused by Chikungunya virus (CHIKV). Symptoms of Chikungunya include debilitating joint pain and swelling, fever and rash. CHIKV was first discovered in 1953 in Tanzania, and has since caused periodic outbreaks of disease. The virus reemerged recently in 2004 and has since spread around the world affecting more than 3 million people. The different strains of CHIKV have been grouped into three phylogenetic clades: West African, Asian and East/Central/South African (ECSA). There are no FDA approved medicines or vaccines used to treat or prevent CHIKV infection. The antiviral drug, T-705 (commercially known as Favipiravir), has …

Vorinostat Renders The Replication-Competent Latent Reservoir Of Human Immunodeficiency Virus (Hiv) Vulnerable To Clearance By Cd8 T Cells., Julia A Sung, Katherine Sholtis, Jennifer Kirchherr, Joann D Kuruc, Cynthia L Gay, Jeffrey L Nordstrom, Catherine M Bollard, Nancie M Archin, David M Margolis

Pediatrics Faculty Publications

Latently human immunodeficiency virus (HIV)-infected cells are transcriptionally quiescent and invisible to clearance by the immune system. To demonstrate that the latency reversing agent vorinostat (VOR) induces a window of vulnerability in the latent HIV reservoir, defined as the triggering of viral antigen production sufficient in quantity and duration to allow for recognition and clearance of persisting infection, we developed a latency clearance assay (LCA). The LCA is a quantitative viral outgrowth assay (QVOA) that includes the addition of immune effectors capable of clearing cells expressing viral antigen. Here we show a reduction in the recovery of replication-competent virus from …

Pixuna Virus Modifies Host Cell Cytoskeleton To Secure Infection, Pedro Ignacio Gil, Guillermo Albrieu-Llinás, Estela Cecilia Mlewski, Marina Monetti, Laura Fozzatti, Cecilia Cuffini, José Fernández-Romero, Patricia Kunda, María Gabriela Paglini

Publications and Research

Pixuna virus (PIXV) is an enzootic member of the Venezuelan Equine Encephalitis Virus complex and belongs to the New World cluster of alphaviruses. Herein we explore the role of the cellular cytoskeleton during PIXV replication. We first identified that PIXV undergoes an eclipse phase consisting of 4 h followed by 20 h of an exponential phase in Vero cells. The infected cells showed morphological changes due to structural modifications in actin microfilaments (MFs) and microtubules (MTs). Cytoskeletonbinding agents, that alter the architecture and dynamics of MFs and MTs, were used to study the role of cytoskeleton on PIXV replication. The …
