Hispanic Agricultural Workers: The Nexus Of Demographics, Employment Characteristics, And Health, Ashley Michelle Bush

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Agriculture, which is home to elevated occupational injury and illness rates, has a substantial demographic makeup of Hispanic workers. Hispanic farmworkers are at increased risk of poor occupational health outcomes due to the precarious nature of work and other socio-ecological influences. These adverse occupational health outcome counts are inadequate and undercounted, failing to capture the true scope of agricultural work. To gain more knowledge about agriculture, this capstone will focus on the personal and work characteristics of agricultural workers to help further understand disparities within the agricultural sector by: providing a literature review of agricultural worker health; examining missed work …

Global Mortality Impact Of The 1957–1959 Influenza Pandemic, Cecile Viboud, Lone Simonsen, Rodrigo Fuentes, Jose Flores, Mark A. Miller, Gerardo Chowell

Global Health Faculty Publications

Background. Quantitative estimates of the global burden of the 1957 influenza pandemic are lacking. Here we fill this gap by modeling historical mortality statistics.

Methods. We used annual rates of age- and cause-specific deaths to estimate pandemic-related mortality in excess of background levels in 39 countries in Europe, the Asia-Pacific region, and the Americas. We modeled the relationship between excess mortality and development indicators to extrapolate the global burden of the pandemic.

Results. The pandemic-associated excess respiratory mortality rate was 1.9/10 000 population (95% confidence interval [CI], 1.2–2.6 cases/10 000 population) on average during 1957–1959. Excess mortality rates varied 70-fold …

Two sampling procedures were carried out in six selected classrooms with similar dimensions that were separated into two groups: (1) UVGI exposure group and (2) non-UVGI control group. Two-stage Tisch culturable impactors were utilized to collect airborne culturable bacteria and fungi. Monthly samples were collected during unoccupied period …

Measuring Quality Of Care: A Review Of Previously Used Methodologies And Indicators, Katherine Tumlinson

Reproductive Health

Despite successful efforts to increase financial and geographic access to family planning services in many parts of the developing world, large numbers of women with a desire to delay or limit future pregnancies are not using contraceptive methods. Several multi-country, large-scale facility surveys incorporate indicators for measuring the quality of family planning service delivery. These facility surveys use data collection tools such as facility audits, provider and client questionnaires, and third party observation guides. A limited body of research indicates that the validity of these tools is low, however, while large variations in analytical approaches inhibit use of existing literature …

Evaluation Of Education And Other Influential Factors On The Perceptions Of Influenza Vaccinations, S. D. Mills, S. R. Charlton, B. M. Rowley

Journal of the Arkansas Academy of Science

Influenza is a potentially deadly contagious viral infection that attacks the respiratory system. The 1918 influenza pandemic infected approximately 1/3 of the world’s population and resulted in an estimated 50 million deaths globally. Research has led to the production of influenza vaccinations. Unfortunately, there continues to be influenza epidemics that are responsible for killing numerous people annually. One reason for the continued death toll from influenza is the lack of people receiving a yearly flu vaccination. In order to gain more public acceptance for influenza vaccinations, it is important to understand the factors influencing the choice to be vaccinated. A …

Knowledge-Based Tweet Classification For Disease Sentiment Monitoring, Xiang Ji, Soon Ae Chun, James Geller

Publications and Research

Disease monitoring and tracking is of tremendous value, not only for containing the spread of contagious diseases but also for avoiding unnecessary public concerns and even panic. In this chapter, we present a near real-time sentiment analysis service of public health-related tweets. Traditionally, it is impossible for humans to effectively measure the degree of public health concerns due to limited resources and significant time delays. To solve this problem, we have developed a computational intelligence approach for Epidemic Sentiment Monitoring System (ESMOS) to automatically analyze the disease sentiments and gauge the Measure of Concern (MOC) expressed by Twitter users. More …

Enteric Fever: A Slow Response To An Old Plague, Carlos Franco- Paredes, M. Imran Khan, Esteban Gonzalez- Diaz, Jose I. Santos- Preciado, Alfonso J. Rodriguez Morales, Eduardo Gotuzzo

Centre of Excellence in Women and Child Health

Man is irremediably embedded in nature with complex interactions with all living organisms. Historically, the establishment of contemporary human societies has been influenced by our coexistence with other microorganisms living in highly interconnected habitats and ecologies. As a result, with the progression from unicellular to multicellular life, bacteria have coexisted with humans. In this biological journey, while there are important benefits provided by bacterial guests to the human host living in complex relationships and becoming part of their microbiome, some organisms are able to cause a wide spectrum of diseases. Among the large Enterobacteriaceae family, the genus Salmonella, a …

Japanese Encephalitis: Assessing Disease Risk Due To Landscape Factors At Multiple Scales, Julia E. Metelka

Theses and Dissertations (Comprehensive)

Japanese Encephalitis is a mosquito-borne disease and is the leading cause of viral encephalitis in Asia. In many Asian countries, the geographical distribution of JE is dependent on a variety of human-environment interactions that can be conceptualized as a complex social-ecological system. The JE transmission cycle is influenced by a few primary human-landscape factors; the abundance and the spatial configuration of rice paddy fields (which provide habitat for the vector), the distribution of pig farms (which position the virus' amplifying host), and the location of a susceptible human population. Our models integrate population dynamics, landscape characteristics, and weather variables that …

Investigating Cholera Using An Sir Model With Age-Class Structure And Optimal Control, K. Renee Fister, Holly Gaff, Elsa Schaefer, Glenna Buford, Bryce C. Norris

Biological Sciences Faculty Publications

The use of systems of differential equations in mathematical modeling in conjunction with epidemiology continues to be an area of focused research. This paper briefly acquaints readers with epidemiology, cholera, and the need for effective control strategies; discusses cholera dynamics through a variation on the SIR epidemiological model in which two separate age classes exist in a population; finds the numeric value for R₀ to be approximately 1.54 using estimated parameters for Bangladesh; and employs an optimal control resulting in a suggestion that a protection control be implemented at the end of the monsoon season.

Political, Economic, And Health Determinants Of Tuberculosis Incidence, Ashley Rutherford

Electronic Theses and Dissertations

The epidemiologic transition has shifted major causes of mortality from infectious disease to chronic disease; however, infectious diseases are again re-emerging as a major global concern (Diamond, 1997; Karlen, 1995; McNeil, 1976). This research aimed to identify potential areas of infectious disease influence that are not health-related in order to help governments and policymakers establish new policies, correct current policies, or further address these issues in order to effectively prevent and combat infectious disease. This study employed a retrospective, cross-sectional, non-experimental design via structural equation modeling (SEM) and examined tuberculosis incidence rates at the country-level. Secondary data from open-source, international …

Best Practices For Controlling Tuberculosis - Training In Correctional Facilities: A Mixed Methods Evaluation, Ellen Reynolds Murray

Walden Dissertations and Doctoral Studies

According to the literature, identifying and treating tuberculosis (TB) in correctional facilities have been problematic for the inmates and also for the communities into which inmates are released. The importance of training those who can identify this disease early into incarceration is vital to halt the transmission. Although some training has been done by public health authorities for corrections, there is little to no evaluation of such training. The aim of this mixed methods retrospective study was to evaluate the effectiveness of a training to control TB in correctional facilities. The Southeastern National Tuberculosis Center (SNTC) conducted 12 trainings between …

Gender Differences In Risk Behaviors And Health Outcomes Due To Methamphetamine Use In A Mexico-U.S. Border City, Priscilla Guevara

Open Access Theses & Dissertations

BACKGROUND: Methamphetamine (meth) is a stimulant known to affect the central nervous system (CNS). When individuals are under the influence of meth, their judgment is impaired which can lead them to make irrational decisions and engage in high-risk behaviors, such as having unprotected sex and needle sharing. Thus the behaviors of meth users can place them at high risk of contracting infectious diseases such as human immunodeficiency virus (HIV) and other sexually transmitted diseases (STDs). Few studies highlight gender differences in meth use, fewer studies address high-risk behaviors and health outcomes attributed to meth use by gender. El Paso, TX …

Faculty, Staff and Student Publications

BACKGROUND: Studies show obesity decreases risk of tuberculosis (TB) disease. There is limited evidence on whether high body mass index also protects against TB infection; how very high body mass indices influence TB risk; or whether nutritional status predicts this risk in children. We assessed the impact of body mass index on incident TB infection and disease among adults and children.

METHODS AND FINDINGS: We conducted a prospective cohort study among household contacts of pulmonary TB cases in Lima, Peru. We determined body mass index at baseline and followed participants for one year for TB infection and disease. We used …
