Alternative Vaccination Schedules (Avs) : Detection Of Avs In New York State Using Immunization Registry Data, Jessica A. Nadeau

Legacy Theses & Dissertations (2009 - 2024)

Intentional deviation from the recommended childhood vaccine schedule (RVS), referred to as an alternative vaccination schedule (AVS) is becoming increasingly prevalent in the United States. Physicians may accommodate vaccine-hesitant parents with an AVS as a compromise position to allow some vaccinations to be given, but in doing so children remain vulnerable to vaccine-preventable disease for a longer period of time. This research expands upon the nascent literature by proposing a unified definition of AVS, quantifying the prevalence of infants following an AVS in New York State (NYS) (exclusive of New York City) by geographic area and community and medical practice …

Exposure To Persistent Organic Pollutants And Metabolic Diseases, Zafar Zayirovich Aminov

Legacy Theses & Dissertations (2009 - 2024)

Background: The metabolic syndrome (MetS) is a group of diseases that tend to occur together, including diabetes, hypertension, central obesity, cardiovascular disease and hyperlipidemia. Exposure to persistent organic pollutants (POPs) such as polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) have been associated with increased risk of development of several of the components of the MetS.

Quantitative Evaluation Of Antibiotic Exposure-Response Relationships Among Patients With Serious Staphylococcal Infections, Thomas Patrick Lodise

Legacy Theses & Dissertations (2009 - 2024)

This dissertation advances our understanding of antimicrobial exposure-response relationships among patients with serious infections due to Staphylococcus aureus. The need is pressing as treatment of this invasive pathogen has been complicated by the development of antibiotic resistance. One antibiotic resistant phenotype of particular concern is methicillin-resistant S. aureus (MRSA). Due to the multi-drug resistant nature of most MRSA strains, vancomycin emerged as the cornerstone of therapy. Although widely used for serious MRSA infections, many clinicians now question its continued utility due to the emergence of MRSA strains with reduced vancomycin susceptibility phenotypes (rVSPs). The literature is developing rapidly, but characterization …

Legacy Theses & Dissertations (2009 - 2024)

Infection with Chlamydia trachomatis is of public health concern because of its adverse effects on reproduction. Women infected with Chlamydia can develop pelvic inflammatory disease, which can lead to serious reproductive system morbidity including ectopic pregnancy and infertility.

Does Intimate Partner Violence Affect The Acceptability Of Expedited Partner Therapy?, Suzanne Elizabeth Beck

Legacy Theses & Dissertations (2009 - 2024)

Background: Studies have identified associations between intimate partner violence (IPV) and elevated risk of sexually transmitted infections (STI). An estimated 6% of women in the United States have experienced physical and/or sexual assault inflicted by an intimate partner in the previous year. Of those with an STI, chlamydia is disproportionately reported for women. In 2009, New York State legalized Expedited Partner Therapy (EPT) for chlamydial infections; however clinicians are lacking guidance with respect to appropriate use of EPT when IPV is a concern.

30-Day Readmission And Emergency Department Visits : Experience Of Diabetes And Abdominal Surgery Patients, Andrea Jane Mathis

Legacy Theses & Dissertations (2009 - 2024)

Nearly one-fifth of Medicare beneficiaries are readmitted within 30 days of a hospital stay. Readmissions contribute to the rising health care costs and they serve as a proxy for overall inpatient quality of care. Policy makers and payers interested in the efficacy of strategies to improve care coordination have scrutinized readmission rates for some time, yet this analysis attends to several remaining gaps in the literature. First, the rising prevalence of diabetes may be an underappreciated driver for readmissions. Second, many abdominal surgery patients require post-operative care, yet the point of care delivery and level of care needed has not …

Effect Of Data Aggregation At Two Geographic Levels On The Association Between Absms And Gonorrhea Rates In Nys, 1999-2001, Christina Michelle Gray

Legacy Theses & Dissertations (2009 - 2024)

This study compared the association between residential area factors and gonorrhea, aggregated at both the census tract versus ZIP code levels. Prior research has found that census block groupings are most optimal in neighborhood-level studies, followed by census tracts and ZIP codes. Because several healthcare databases currently only provide ZIP code level data, the aim of this study was to examine whether there exists a meaningful difference between the interpretation of census tract and ZIP code aggregate data. Our study measured the association between socioeconomic factors and gonorrhea in New York State, exclusive of New York City (NYC), census tracts …

Augmenting Program Data With Secondary Data Sources To Improve The Quality Of Existing Statistics : Four Examples From The New York State Department Of Health Hospital-Acquired Infection Reporting Program, Valerie Benson Haley

Legacy Theses & Dissertations (2009 - 2024)

The objective of this dissertation is to illustrate the novel application of methods that can be used to improve the accuracy of hospital-acquired infection (HAI) rates. Public reporting of HAI rates is relatively new. New York was one of the first states to mandate reporting in acute care hospitals (2007), followed by national pay-for-reporting in 2011, and national value-based purchasing in 2013. Given the financial ramifications of public reporting, it is critical that the data are validated and adjusted for differences in underlying risk among patient populations so that hospital performance can be fairly compared. However, limited information on the …

Using Geospatial Technologies To Characterize Relationships Between Travel Behavior, Food Availability, And Health, Warren J. Christian

Theses and Dissertations--Geography

Epidemic obesity in the U.S. has prompted exploration of causal factors related to the built environment. Recent research has noted statistical associations between the spatial accessibility of retail food sources, such as supermarkets, convenience stores, and restaurants, and individual characteristics such as weight, socioeconomic status, and race/ethnicity. These studies typically use residential proximity or neighborhood density to food sources as the measure of accessibility. Assessing food environments in this manner, however, is very limiting. Since most people travel outside of their neighborhood on a daily basis, the retail food sources available to individuals residing in the same area could vary …

Data Mining And Pattern Discovery Using Exploratory And Visualization Methods For Large Multidimensional Datasets, Hsin-Fang Li

Theses and Dissertations--Epidemiology and Biostatistics

Oral health problems have been a major public health concern profoundly affecting people’s general health and quality of life. Given that oral health data is composed of several measurable dimensions including clinical measurements, socio-behavioral factors, genetic predispositions, self-reported assessments, and quality of life measures, strategies for analyzing multidimensional data are neither computationally straightforward nor efficient. Researchers face major challenges to identify tools that circumvent the processes of manually probing the data.

The purpose of this dissertation is to provide applications of the proposed methodology on oral health-related data that go beyond identifying risk factors from a single dimension, and to …

Associations Between The Perceived And Built Food Environment, Timothy L. Barnes

Theses and Dissertations

Neighborhood food environments have been associated with dietary intake and obesity. Measures of the food environment have typically been characterized with geographic information systems (GIS)-based measures, however, the use of perception-based measures of the food environment have increased in frequency. Few studies have fully examined the relationship between perceptions and GIS-based measures of the food environment, especially considering the congruency between perceived and GIS-based presence of specific retail food outlets, nor the relationship between food outlets and perceived availability of healthy foods or fast food opportunities.

Telephone survey data from 705 residents in an eight-county region of South Carolina were …

Food Environment And Birth Outcomes In South Carolina, Xiaoguang Ma

Theses and Dissertations

An increasing number of studies examined the association between neighborhood characteristics and birth outcomes. However, the results can be difficult to compare because of the variety of indicators used to characterize the neighborhood. As an important neighborhood characteristic, the food environment is associated with residents' nutrition status, diet quality, and related health outcomes. In addition, the food environment has been found to influence women's diet quality during pregnancy, which is a key factor in predicting birth outcomes. However to date, studies on food environment and birth outcomes are extremely limited.

This study examined the association between food environment (evaluated by …

Geographical Proximity To Health Facilities And Breast Cancer Morbidity And Mortality Among Women In South Carolina's Best Chance Network, Leepao Khang

Theses and Dissertations

Death rates for breast cancer have steadily decreased in women due to early detection, such as mammography, and improved treatments. Despite the benefit of mammography, many women are not up-to-date on screening and do not receive timely follow-up after abnormal mammogram finding. Breast cancer is a major contributor to morbidity and mortality among women in South Carolina. To reduce the disproportionate burden of breast cancer and cervical cancer among women in South Carolina, the South Carolina Best Chance Network (BCN) was established to provide service delivery and ensures timely and complete diagnostic follow-up and treatment initiation for underserved women.

The …

Association Between Breastfeeding And Infant Growth: A Probable Reverse Causality, Shraddha Vyas

Theses and Dissertations

Background: Much conflicting results exist in the association between breastfeeding and infant growth. One of these confusions is related to the temporal sequence between breastfeeding practice and infant growth.

Objective: This study aimed at examining the association and investigating a possible reverse causality between breastfeeding and infant growth.

Method: Infant Feeding Practices Survey II, a national longitudinal database with repeated measurements, following women prenatally and until one year postpartum (N=2914) was used. Mixed linear model assessed the impact of breastfeeding from the 2nd, 4th, 6th and 9th months on infant growth at the 3rd, 5th, 7th and 12th months, respectively. …

Cattle-Related Injuries And Farm Management Practices On Kentucky Beef Cattle Farms, Steven R. Browning, Susan C. Westneat, Wayne T. Sanderson, Deborah B. Reed

Epidemiology and Environmental Health Faculty Publications

While working on farms with livestock increases the risk of injury among farm workers in comparison to other commodity farms, few studies have examined the role offarm management practices in association with the risk of cattle-related injury. We examined the farm management practices of Kentucky beef cattle farms in association with self-reported rates of cattle-related injuries among workers. We conducted a mail survey of a random sample of 2,500 members of the Kentucky Cattlemen's Association. Results from 1,149 farm operators who were currently raising beef cattle and provided complete survey response are reported. During the busy season, the principal operator …

Exploring Potential Risk Factors Of Fetal Origins Of Diabetes: Maternal Stressors During Pregnancy And Birth Outcomes Among Women In A Hospital In The Municipality Of Caguas, Puerto Rico, Juan Pablo Arroyo

USF Tampa Graduate Theses and Dissertations

Puerto Rico has the highest prevalence of type 2 diabetes, low birth-weight, and the second highest prevalence of preterm-birth in all the U.S. and its non-incorporated territories. These conditions are related. Birth-weight at both ends of the spectrum and preterm-birth are associated with an increased risk for developing type 2 diabetes and immune-inflammatory dysregulations. Maternal psychosocial stressors during pregnancy have also been recognized as potential risk factors for type 2 diabetes, and have been consistently associated with preterm-birth and low birth-weight across populations. Current evidence points toward epigenetic fetal metabolic-programming as the mechanism that underlies the increased risk for the …
