Sexual transmission of HIV requires exposure to the virus and infection of activated mucosal immune cells, specifically CD4+ T cells or dendritic cells. The foreskin is a major site of viral entry in heterosexual transmission of HIV. Although the probability of acquiring HIV from a sexual encounter is low, the risk varies even after adjusting for known HIV risk factors. The genital microbiome may account for some of the variability in risk by interacting with the host immune system to trigger inflammatory responses that mediate the infection of mucosal immune cells. We conducted a case-control study of uncircumcised participants …
Syphilis In Men That Have Sex With Men, Nathaniel Helser
Syphilis In Men That Have Sex With Men, Nathaniel Helser
Nursing Student Class Projects (Formerly MSN)
Syphilis rates in the United States hit their nadir in the 1960’s and 1970’s with almost complete disappearance during the 1980’s in conjunction with the onset of the human immunodeficiency virus outbreak (Read et al, 2015). This dramatic fall was a direct consequence of the introduction of penicillin in the 1940’s, but since this decline a widely documented reemergence in endemic levels has been seen across the country (Petrosky et al, 2016). Recent rates in men have jumped from 3 per 100,000 to 9.8 per 100,000 (Petrosky et al, 2016) in a two year span, an alarming increase, which has …

Kingella Kingae: Emerging Outbreaks In Daycare Facilities, Kimberly Iracki
Nursing Student Class Projects (Formerly MSN)
In today’s Western countries, families are more likely than those of past decades to include two full-time working parents. This has led to an increase in he number of children attending daycare or some form of childcare outside the home. It is known that close quarters or semi-confined setting increase the risk of certain infections. Out of these infections, an emerging pediatric pathogen, that has also shown some prevalence in adults, is Kingella kingae.

Coliphage As An Indicator Of The Quality Of Beach Water To Protect The Health Of Swimmers In Coastal Georgia, Javier Gallard-Gongora, Kathryn Munck, Jeff Jones, Asli Aslan
Journal of the Georgia Public Health Association
Background: Gastrointestinal disease affects millions of people in the United States and places a substantial economic burden upon healthcare systems. Recreational waters polluted with fecal material are a main source for transmission of gastrointestinal disease. Georgia beaches are monitored for the presence of fecal indicator bacteria, but these bacteria are not well associated with enteric viruses. The United States Environmental Protection Agency (US EPA) has recently proposed coliphage (a virus of Escherichia coli) as an alternative indicator of fecal contamination in recreational waters. The present study compares fecal indicator bacteria and coliphage concentrations at two Georgia beaches with adjacent creeks …

Physician Attitudes Toward The Ethics Of Pre-Exposure Prophylaxis (Prep): Cost, Safety, And Resource Allocation, Jessica Grippo, Stacy W. Smallwood, Katherine Pincura, Tamara Wright, William A. Mase
Journal of the Georgia Public Health Association
Background: In the United States, human immunodeficiency virus (HIV) remains a substantial public health issue. There is evidence that the use of antiretroviral medications such as pre-exposure prophylaxis (PrEP) can be a safe and effective primary prevention strategy to reduce new cases of HIV infection. Provider practice behavior as it relates to prescribing PrEP and the potential impact on specific vulnerable populations needs increased attention. Few studies have evaluated the attitudes of physicians towards ethical issues related to prescribing PrEP.
Methods: The purpose of the present literature review was to evaluate provider attitudes toward the ethics of prescribing PrEP for …
Leveraging Partnerships In Order To Increase Notifiable Disease Reporting, Jessica Grippo, Amber Erickson
Leveraging Partnerships In Order To Increase Notifiable Disease Reporting, Jessica Grippo, Amber Erickson
Journal of the Georgia Public Health Association
Background: Notifiable disease reporting, although required by law, does not always occur. For this reason, it is crucial for local public health agencies to leverage new partnerships for reporting of notifiable diseases. Schools represent sites within communities that experience relatively high numbers of cases of notifiable disease and clusters of illness. By leveraging partnerships with schools, an increase in disease reporting can occur within communities.
Methods: DeKalb County Board of Health has developed an infectious disease protocol for the two major school systems in the county and one large private school: DeKalb County School District, City Schools of Decatur and …

The Effect Of Antigen Polymorphisms On Serological Antibody Detection Assays Based Upon The, Kristi M. Miley
USF Tampa Graduate Theses and Dissertations
Onchocerca volvulus is a filarial parasite transmitted to humans by female Simulium spp. black flies. Infection with this parasite can cause blindness and severe skin disease among humans in Africa and the Americas. Enzyme-linked Immunosorbent Assay serological testing of OV-16 antigen is a diagnostic tool for determining effective elimination of the parasite. Programs typically rely on OV–16 ELISA to evaluate the progress towards interruption and/or elimination of disease by mass drug distribution of ivermectin and vector larvicidal control efforts. As elimination grows closer, monoclonal antibody positive controls for OV-16 ELISA become important to develop for Onchocerca testing due to the …

Analysis Of A Potential A(H7n9) Influenza Pandemic Outbreak In The U.S., Walter A. Silva Sotillo
USF Tampa Graduate Theses and Dissertations
This dissertation presents a collection of manuscripts that describe development of models and model implementation to analyze impact of potential A(H7N9) pandemic influenza outbreak in the U.S. Though this virus is still only animal-to-human transmittable, it has potential to become human-to-human transmittable and trigger a pandemic. This work is motivated by the negative impact on human lives that this virus has already caused in China, and is intended to support public health officials in preparing to protect U.S. population from a potential outbreak of pandemic scale.
An agent-based (AB) simulation model is used to replicate the social dynamics of the …
Immunizations And Health Disparities: Immunizations Provided Across A Diverse Population, Jeffery A. Goad, Tania Gregorian
Immunizations And Health Disparities: Immunizations Provided Across A Diverse Population, Jeffery A. Goad, Tania Gregorian
Pharmacy Faculty Articles and Research
"Vaccines help contain the spread of diseases and reduce morbidity and mortality. For any vaccination effort to succeed, vaccine uptake must be widespread across the entire population. However, the US population is very diverse, and there are various groups with different attitudes and beliefs regarding vaccination; this leads to disparities in vaccination rates. The Healthy People initiative, a program managed by Office of Disease Prevention and Health Promotion at the US Department of Health and Human Services HHS that aims to provide Americans with evidence-based, 10-year national objectives for improving their health defines a disparity in health care as 'a …
Trafficking Victims In The Emergency Room Setting, Lisa M. Archer
Trafficking Victims In The Emergency Room Setting, Lisa M. Archer
Theses and Graduate Projects
Human trafficking, a form of modern-day slavery, is a violation of human rights and a public health issue. Affecting millions worldwide, a high prevalence of human trafficking exists in the United States (US). Traffickers target vulnerable victims in an effort, through coercion and exploitation, to benefit financially, perpetuating the issue of supply and demand. Lacking a specific demographic, traffickers opportunistically seek out victims, such as targeting runaway and homeless youth, those sold through poverty, or those surviving in conditions caused by natural disaster. Multidisciplinary health care staff are uniquely positioned to recognize, assess, and intervene when encountering victims who seek …

Microscopic Analysis And Quality Assessment Of Induced Sputum From Children With Pneumonia In The Perch Study., David R Murdoch, Susan C Morpeth, Laura L Hammitt, Amanda J Driscoll, Daniel E Park, +Several Additional Authors
Epidemiology Faculty Publications
Background.
It is standard practice for laboratories to assess the cellular quality of expectorated sputum specimens to check that they originated from the lower respiratory tract. The presence of low numbers of squamous epithelial cells (SECs) and high numbers of polymorphonuclear (PMN) cells are regarded as indicative of a lower respiratory tract specimen. However, these quality ratings have never been evaluated for induced sputum specimens from children with suspected pneumonia. Methods.
We evaluated induced sputum Gram stain smears and cultures from hospitalized children aged 1–59 months enrolled in a large study of community-acquired pneumonia. We hypothesized that a specimen representative …

Is Higher Viral Load In The Upper Respiratory Tract Associated With Severe Pneumonia? Findings From The Perch Study., Daniel R Feikin, Wei Fu, Daniel E Park, Qiyuan Shi, Melissa M Higdon, Henry C Baggett, +Several Additional Authors
Epidemiology Faculty Publications
Background.
The etiologic inference of identifying a pathogen in the upper respiratory tract (URT) of children with pneumonia is unclear. To determine if viral load could provide evidence of causality of pneumonia, we compared viral load in the URT of children with World Health Organization–defined severe and very severe pneumonia and age-matched community controls.
Methods.
In the 9 developing country sites, nasopharyngeal/oropharyngeal swabs from children with and without pneumonia were tested using quantitative real-time polymerase chain reaction for 17 viruses. The association of viral load with case status was evaluated using logistic regression. Receiver operating characteristic (ROC) curves were constructed …

Association Of C-Reactive Protein With Bacterial And Respiratory Syncytial Virus-Associated Pneumonia Among Children Aged <5 Years In The Perch Study., Melissa M Higdon, Tham Le, Katherine L O'Brien, David R Murdoch, Christine Prosperi, Henry C Baggett, Daniel E Park, +Several Additional Authors
Epidemiology Faculty Publications
Background.
Lack of a gold standard for identifying bacterial and viral etiologies of pneumonia has limited evaluation of C-reactive protein (CRP) for identifying bacterial pneumonia. We evaluated the sensitivity and specificity of CRP for identifying bacterial vs respiratory syncytial virus (RSV) pneumonia in the Pneumonia Etiology Research for Child Health (PERCH) multicenter case-control study. Methods.
We measured serum CRP levels in cases with World Health Organization–defined severe or very severe pneumonia and a subset of community controls. We evaluated the sensitivity and specificity of elevated CRP for “confirmed” bacterial pneumonia (positive blood culture or positive lung aspirate or pleural fluid …

Background.
Sputum microscopy and culture are commonly used for diagnosing the cause of pneumonia in adults but are rarely performed in children due to difficulties in obtaining specimens. Induced sputum is occasionally used to investigate lower respiratory infections in children but has not been widely used in pneumonia etiology studies. Methods.
We evaluated the diagnostic utility of induced sputum microscopy and culture in patients enrolled in the Pneumonia Etiology Research for Child Health (PERCH) study, a large study of community-acquired pneumonia in children aged 1–59 months. Comparisons were made between induced sputum samples from hospitalized children with radiographically confirmed pneumonia …

The New York City Childcare Influenza Vaccine Mandate: A Case Study, Amy E. Metroka
Dissertations and Theses
Background. In 2014, New York City (NYC) became the third jurisdiction in the United States (US) to enact a childcare influenza vaccine mandate, after the states of New Jersey and Connecticut. The mandate was enacted by the NYC Board of Health by amending the NYC Health Code. The mandate’s goal was to increase vaccination rates among 6-59-month-olds attending city-regulated public and private childcare programs, including prekindergarten, to protect children, families, and the community against influenza. Children younger than 5 years are at high risk for severe illness and complications from influenza. Children are also known to be a major source …

The case-control methodology is frequently used to evaluate vaccine effectiveness post-licensure. The results of such studies provide important insight into the level of protection afforded by vaccines in a 'real world' context, and are commonly used to guide vaccine policy decisions. However, the potential for bias and confounding are important limitations to this method, and the results of a poorly conducted or incorrectly interpreted case-control study can mislead policies. In 2012, a group of experts met to review recent experience with case-control studies evaluating vaccine effectiveness; we summarize the recommendations of that group regarding best practices for data collection, analysis, …
