State Space Analysis Of Dominant Structures In Dynamic Social Systems, Jeremy B. Sato

McKelvey School of Engineering Graduate Student Theses & Dissertations

Many systems involving human relationships are modeled as dynamic systems, as diverse as urban population growth, diffusion of innovations, spread of viruses, and supply chain management. A fundamental assumption is that these systems contain variables which accumulate and deplete over time (people, innovation adoptions, infections, and orders), and whose dynamics are determined by societal rules and human decision making processes. These assumptions allow the system to be formally expressed by ordinary differential equations which are often nonlinear and contain multiple state variables and feedback loops. Analytical methods have been developed to identify the dominant feedback loops which primarily influence the …

The Right For Autonomy, The Duty Of Disclosure And Public Health Considerations – The 2013 Polio Crisis In Israel As A Case Study, Dr. Nili Karako Eyal

Pace Law Review

Despite sharing the same theoretical framework of discussion with other papers, this paper addresses an ethical and legal issue that has received little attention in academic and public discourse: the duty of disclosure in the context of vaccinations. In particular, the paper addresses the question whether public health considerations provide a justification for restricting the duty of disclosure in the case of vaccination.

Delimitating the research question to the issue of disclosure has several implications. First, the decision to vaccinate the population with bOPV as describe above and the decision to adopt a voluntary vaccination policy are not the focus …

Detection Of Zoonotic Enteropathogens In Children And Domestic Animals In A Semirural Community In Ecuador., Karla Vasco, Jay P Graham, Gabriel Trueba

Environmental and Occupational Health Faculty Publications

UNLABELLED: Animals are important reservoirs of zoonotic enteropathogens, and transmission to humans occurs more frequently in low- and middle-income countries (LMICs), where small-scale livestock production is common. In this study, we investigated the presence of zoonotic enteropathogens in stool samples from 64 asymptomatic children and 203 domestic animals of 62 households in a semirural community in Ecuador between June and August 2014. Multilocus sequence typing (MLST) was used to assess zoonotic transmission of Campylobacter jejuni and atypical enteropathogenic Escherichia coli (aEPEC), which were the most prevalent bacterial pathogens in children and domestic animals (30.7% and 10.5%, respectively). Four sequence types …

Using The Theory Of Fundamental Causes To Show The Potential Effects Of Socioeconomic Status On Surgical Outcomes, Mehwish Qasim, A.B.D.

Bridging The Gap Between Local Public Health And The Healthcare Community: The Public Health Talk, Puja Bharucha, Rachel Franklin

Journal of the Georgia Public Health Association

Background: District epidemiologists often rely on healthcare providers for medical information regarding reportable diseases in order to properly investigate cases. It becomes difficult when providers do not share patient information due to apprehension and/or lack of knowledge of HIPAA exemption laws. It is also challenging when the provider staff is not knowledgeable regarding disease specific information. When information is withheld, there is a delay in completing investigations, and high priority cases and outbreaks such as emerging infectious diseases can be missed or lost to follow up.

Methods: The Public Health Talk (The Talk) initiative was established at Cobb and Douglas …

Journal of the Georgia Public Health Association

Background: Sustainability and mitigation in preparedness after grant money is gone has suddenly become a hot topic in the public health emergency preparedness world. By the same token, funding provided by the Federal Emergency Management Agency (FEMA) for individual preparedness initiatives has not had the desired mitigation impacts. The question becomes, are there alternative approaches that reach more individuals to build a culture of preparedness in communities? One solution involves the leveraging of academic and regional public health partnerships with their Medical Reserve Corps Units (MRC), to train college students in individual preparedness. The purpose of this study is to …

Will The Ebola Epidemic Serve To Make Reform Of The Broken Health Research And Development Framework Go Viral?, Jeremy Mcdonald

Indiana Journal of Global Legal Studies

The recent Ebola outbreak in West Africa has captured the public imagination as few other epidemics have, as its rapid spread and lethal effect demonstrated the devastating toll that infectious diseases can exact from a world unprepared to confront them. In light of the epidemic's tragic consequences, numerous experts have called for reform of the system of global health governance whose shortfalls allowed the epidemic to assume the horrifying dimensions it did. Among the many inadequacies that the outbreak uncovered is the insufficient amount of research into and development of treatments and vaccines for infectious diseases of poverty, among them …

Development Of A Rt-Pcr-Elisa Wuchereria Bancrofti Detection Assay For The Monitoring Of Mosquito Vector Infection And Infectivity, Nompumelelo Mzizi Mzizi

USF Tampa Graduate Theses and Dissertations

Lymphatic filariasis (LF) is an incapacitating disease caused by three filarial nematodes belonging to the family Onchocercidae, namely Brugia timori, Wuchereria bancrofti and Brugia timori. An estimated 90% of lymphatic filariasis cases globally are caused by Wuchereria bancrofti. To evaluate the success of the Global Program to eliminate Lymphatic Filariasis it is essential to monitor the frequency of larval infection in the mosquito vector. Molecular methods to detect Wuchereria bancrofti DNA in mosquitoes have been in existence since 1996. However these methods have not been widely adopted due to the high cost associated with them and the inability …

Molecular Cues Of Pattern-Recognition-Receptor Pathways In Redox-Toxicity-Driven Environmental Nafld, Suvarthi Das

Theses and Dissertations

With the pandemic proportions of obesity and a correlative increase in fatty liver disease, there was a dire need to explore the missing link between the changed environment and progression of NAFLD in obesity. My research implies that environmental toxin bromodichloromethane induces early liver lesions in obesity, and is mediated by the synchronous insult of oxidative stress and increased levels of the adipokine leptin. In a two-pronged approach to investigate the molecular cues, I looked at the role of Purinergic receptor X7 and Toll 4 receptor. Both rodent models and cell-based systems were used. Also, in order to validate my …

Assessment Of Prolonged Occupational Exposure To Heat Stress, Ximena Garzon-Villalba Garzon-Villalba

USF Tampa Graduate Theses and Dissertations

Heat stress is a recognized occupational hazard present in many work environments. Its effects increase with increasing environmental heat loads. There is good evidence that exertional heat illness is associated with ambient thermal conditions in outdoor environments. Further, there is reason to believe that risk of acute injury may also increase with the ambient environment. For these reasons, the assessment of heat stress, which can be done through the characterization of the wet bulb globe temperature (WBGT), is designed to limit exposures to those that could be sustained for an 8-h day. The ACGIH Threshold Limit Value (TLV) for heat …

Smoking Among Youth Living With Hiv: The Intersection Of Behavioral Health And Chronic Disease, Todd Wells

USF Tampa Graduate Theses and Dissertations

Smoking amongst youth living with HIV (YLWH) has major public health implications. When combined with the complications associated with smoking such as chronic obstructive pulmonary disorder (COPD) or heart disease, the impact of a HIV positive diagnosis increases morbidity exponentially (Nahvi & Cooperman, 2009). The purpose of this study was two-fold, to investigate the perceptions of smoking amongst YLWH aged 18-25 who received care at the CMS Clinic located at the University of South Florida and to determine factors related to cessation. A study design utilizing two components, a systematic literature review and primary qualitative data was used in this …

Developing A Video-Based Ehealth Intervention For Hiv-Positive Gay, Bisexual, And Other Men Who Have Sex With Men: Study Protocol For A Randomized Controlled Trial, Sabina Hirshfield, Martin J. Downing Jr., Jeffrey T. Parsons, Christina Grov, Rachel J. Gordon, Steven T. Houang, Roberta Scheinmann, Patrick S. Sullivan, Irene S. Yoon, Ian Anderson, Mary Ann Chiasson

Publications and Research

Background: Gay, bisexual, and other men who have sex with men (GBMSM) accounted for 67% of new US human immunodeficiency virus (HIV) infections in 2012; however, less than 40% of HIV-positive GBMSM are virally suppressed. Preventing transmission from virally unsuppressed men who have condomless anal sex (CAS) with serodiscordant partners is a public health imperative. New HIV infections in GBMSM are attributed in part to online access to sex partners; therefore, low-cost eHealth interventions are a unique opportunity to reach men where they meet partners.

Objective: To describe the protocol of a randomized controlled trial evaluating whether video-based messaging delivered …

Gauci, Elli Leontsini, Robert H. Gilman

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Taeniasis and cysticercosis are major causes of seizures and epilepsy. Infection by the causative parasite Taenia solium requires transmission between humans and pigs. The disease is considered to be eradicable, but data on attempts at regional elimination are lacking. We conducted a three-phase control program in Tumbes, Peru, to determine whether regional elimination would be feasible.

Methods: We systematically tested and compared elimination strategies to show the feasibility of interrupting the transmission of T. solium infection in a region of highly endemic disease in Peru. In phase 1, we assessed the effectiveness and feasibility of six intervention …

Identification Of Ecdysone Hormone Receptor Agonists As A Therapeutic Approach For Treating Filarial Infections, Amruta S. Mhashilkar, Sai L. Vankayala, Canhui Liu, Fiona Kearns, Priyanka Mehrotra, George Tzertzinis, Subba R. Palli, H. Lee Woodcock, Thomas R. Unnasch

Entomology Faculty Publications

Background A homologue of the ecdysone receptor has previously been identified in human filarial parasites. As the ecdysone receptor is not found in vertebrates, it and the regulatory pathways it controls represent attractive potential chemotherapeutic targets.

Methodology/ Principal Findings Administration of 20-hydroxyecdysone to gerbils infected with B. malayi infective larvae disrupted their development to adult stage parasites. A stable mammalian cell line was created incorporating the B. malayi ecdysone receptor ligand-binding domain, its heterodimer partner and a secreted luciferase reporter in HEK293 cells. This was employed to screen a series of ecdysone agonist, identifying seven agonists active at …

Lack Of An Association Or An Inverse Association Between Low-Density-Lipoprotein Cholesterol And Mortality In The Elderly: A Systematic Review, Uffe Ravnskov, Rokura Hama, Tomohito Hamazaki, Paul J. Rosch, Tore Schersten, Ralf Sundberg

NYMC Faculty Publications

OBJECTIVE: It is well known that total cholesterol becomes less of a risk factor or not at all for all-cause and cardiovascular (CV) mortality with increasing age, but as little is known as to whether low-density lipoprotein cholesterol (LDL-C), one component of total cholesterol, is associated with mortality in the elderly, we decided to investigate this issue.

SETTING, PARTICIPANTS AND OUTCOME MEASURES: We sought PubMed for cohort studies, where LDL-C had been investigated as a risk factor for all-cause and/or CV mortality in individuals ≥60 years from the general population.

RESULTS: We identified 19 cohort studies including 30 cohorts with …

Childhood Health Status And Adulthood Cardiovascular Disease Morbidity In Rural China: Are They Related?, Qing Wang, Jay Shen

School of Public Health Faculty Research

Cardiovascular diseases (CVDs) are among the top health problems of the Chinese population. Although mounting evidence suggests that early childhood health status has an enduring effect on late life chronic morbidity, no study so far has analyzed the issue in China. Using nationally representative data from the 2013 China Health and Retirement Longitudinal Study (CHARLS), a Probit model and Two-Stage Residual Inclusion estimation estimator were applied to analyze the relationship between childhood health status and adulthood cardiovascular disease in rural China. Good childhood health was associated with reduced risk of adult CVDs. Given the long-term effects of childhood health on …
