A Social And Ecological Approach To Mosquito Species Distribution Across Land Use In Bangor, Maine, Megan L. Schierer
A Social And Ecological Approach To Mosquito Species Distribution Across Land Use In Bangor, Maine, Megan L. Schierer
Electronic Theses and Dissertations
Mosquitoes are ubiquitous pests and infectious disease vectors. However, not all mosquito species bite humans, or are competent pathogen vectors between bloodmeal hosts. Along with climatic variables like temperature and rainfall, mosquito species distribution is determined by aquatic habitat availability for juvenile mosquito development, and terrestrial habitat and host availability for adult mosquitoes. There is variation in the preferred aquatic habitat for gravid female oviposition and subsequent larval development. Some mosquito species’ oviposition and development are associated with ephemeral water sources (e.g., floodplains), others prefer more permanent water sources (e.g., bogs or vernal pools). Other mosquitoes have evolved to occupy …
The Need For Racial And Ethnic Health Disparity Curriculum In Genetic Counseling Programs, Yusra Aziz
The Need For Racial And Ethnic Health Disparity Curriculum In Genetic Counseling Programs, Yusra Aziz
Dissertations & Theses (Open Access)
Racial and ethnic health disparities (REHD) exist across all organized medicine, including the spectrum of genetic counseling, particularly in genomic testing and access to care. While cultural competency and health disparities have been included as a part of the Standards of Accreditation for Genetic Counseling, there have not been previous efforts to define what topics related to REHD are most important to include in graduate program curriculum. Therefore, this study aimed to determine what topics related to REHD should be taught in genetic counseling program curriculum by assessing what topics genetic counselors (GCs) learned about and in what settings, …
Therapeutic Approaches To Working With Perinatal Loss Clients: A Grounded Theory Study, Heather H. Olivier
Therapeutic Approaches To Working With Perinatal Loss Clients: A Grounded Theory Study, Heather H. Olivier
University of New Orleans Theses and Dissertations
Perinatal loss (i.e., miscarriage, stillbirth, termination, and infant death) is commonly referred to in the literature as an invisible loss, non-loss, and even medical event. It is an ambiguous loss exhibiting the dialectical contradiction between the physical absence and psychological presence of the baby accompanied by disenfranchised grief, a reaction to a loss that is unacknowledged by society. Despite the likelihood of mental health clinicians working with clients who have experienced perinatal loss, there has yet to be a therapeutic model designed specifically for the unique grief and trauma reactions presented in this population. Existing grief models do not address …
Effect Of Temperature On The Microbiome Of A Laboratory-Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna L. Mitchell
Effect Of Temperature On The Microbiome Of A Laboratory-Reared Colony Of Haemaphysalis Longicornis Ticks, Brianna L. Mitchell
Honors Theses
Haemaphysalis longicornis ticks are invasive to the United States with potential to transmit several tick-borne pathogens that are native to the United States. Based on existing locations of H. longicornis in its native regions in Asia, as well as its invasive populations that are established in the United States, several geographic range prediction models have been produced to help understand future range expansion and distribution of this invasive tick in North America. Unfortunately, these models do not all agree and there is uncertainty associated with the potential geographic range expansion of H. longicornis ticks in North America. Climate can affect …

Children and adolescents spend the majority of their day engaged in sedentary behaviors (SB), while also not meeting physical activity (PA) recommendations. The failure to develop and maintain health enhancing behaviors from a young age may impact an individual throughout their life. With children and adolescents spending a large proportion of their waking hours in a school setting, the educational environment presents an opportunity in which children and adolescents’ PA and SB can be positively influenced. Therefore, the purpose of this dissertation was to explore how children and adolescent’s school time PA and SB are associated with the educational setting, …
An Investigation Of Resistance Training Behavior, Non-Specific Psychological Distress, And Perceived Barriers To Resistance Training In Self-Identifying Female Undergraduate Students, Jody Sobel
Master's Theses
The prevalence and severity of depression symptoms amongst college students, specifically female identifying undergraduate students, is worrisome. There is a great deal of research that suggests a relationship between exercise, specifically resistance training (RT), and mental health. That said, current literature suggests that many female identifying students are not engaging due to perceived barriers. This, perhaps because of the plethora of barriers one can perceive. The purpose of this study was multifold 1) to examine the prevalence and severity of non-specific psychological distress; 2) to determine if there were differences between Kessler 6 Non-Specific Psychological Distress Scale (K6) categories (i.e., …

Understanding what methods are optimal for diagnosing UTIs are critical to mitigate the marked impact and cost of these infections.
Chapter 1 and 2 in this work surveys the broad array of diagnostic modalities for UTIs and highlights their advantages and limitations in the context of the current standard of …
Bifidobacterial Metabolism Of Fucosylated Human Milk Oligosaccharides Influences Structure And Function Of The Infant Gut Microbiome, Liv R. Dedon
Doctoral Dissertations
Human milk contains human milk oligosaccharides (HMOs) that are indigestible and pass intact through the infant gastrointestinal tract where they are available for microbial metabolism. HMOs incorporate the same monosaccharide building blocks but vary structurally in primary sequence of monomeric components. Primary sequences are further diversified by degree of polymerization, branching, and secondary modifications such as fucosylation. Fucosylated HMOs (fHMOs) are highly abundant and can account for over 30% of total HMOs. Infant-colonizing Bifidobacterium longum subsp. infantis (B. infantis) possesses a specialized gene cluster conveying the ability to metabolize fHMOs. This study presents an in-depth analysis of B. …
Accuracy Of Therapeutic Drug Monitoring In Vancomycin And The Pharmacist Role: A Retrospective Case-Series, Kateryna Parkhomenko
Accuracy Of Therapeutic Drug Monitoring In Vancomycin And The Pharmacist Role: A Retrospective Case-Series, Kateryna Parkhomenko
Senior Theses
Vancomycin is a mainstay of therapy for treating virulent and resistant infections, especially methicillin-resistant Staphylococcus aureus (MRSA). However, vancomycin requires therapeutic drug monitoring (TDM) for optimal dosing and treatment. This requires pharmacists to calculate a dosing regimen that correlates to appropriate goal vancomycin concentrations in the blood. Dosing vancomycin can be difficult, as it varies on a patient’s weight, renal function, age, etc. Doses may have to be adjusted in response to out-of-range concentrations, which requires further pharmacy calculations. Inaccurate dosing poses a risk to patient safety and places a resource and time burden on pharmacists. If vancomycin dosing methods …
Diet And Salivary Microbiome On Cardiovascular Risk And Glycemic Control In Participants With And Without Type 1 Diabetes: The Cacti Study, Tiantian Pang
USF Tampa Graduate Theses and Dissertations
Introduction: The prevalence of type 1 diabetes mellitus (T1DM) has been increasing drastically in the United States. People with T1DM are at a higher risk of developing diabetes-related complications, including cardiovascular disease (CVD). Diet is one of the most modifiable factors and healthy eating could reduce CVD risk among individuals with T1DM. The current 2015-2020 Dietary Guidelines for Americans focus on overall healthy eating patterns rather than individual foods and nutrients. A healthy dietary pattern or high-quality diet can be measured by diet quality indexes, and generally contains minimal ultra-processed foods (UPF). Although substantial evidence has linked poor diet quality …
Using The Genetic Counseling Skills Checklist To Characterize Prenatal Genetic Counseling, David A. Cline
Using The Genetic Counseling Skills Checklist To Characterize Prenatal Genetic Counseling, David A. Cline
USF Tampa Graduate Theses and Dissertations
Genetic Counseling relies on communication skills to help patients understand and adapt to a genetic disease or risk. However, little is known about which skills are most commonly used or the extent to which genetic counseling sessions vary. A novel process measure titled the "Genetic Counseling Skills Checklist" (GCSC) was developed in a prior pilot study and includes 8 broad categories each consisting of 5-8 skills. This study is the first to apply the final GCSC to characterize 20 mock prenatal sessions conducted by 5 genetic counselors (GCs) for 2 prenatal indications using 3 trained actors as patients.

Sit Less, Move More: A National Study Of Physical-Activity Behavior And Cancer, Stella O. Nwogugu
Dissertations, Theses, and Capstone Projects
Background: Physical activity is associated with lower risks of cancer, the second leading cause of death among Americans. Yet, sedentary behavior is the prevailing lifestyle for about 80% of American adults. Additionally, cancer survivors remain significantly inactive, even though physical activity has been shown to decrease risk of cancer and cancer recurrence, improve tolerance of cancer therapy, and reduce mortality. This research explores the relative impact of personal agency, social support, and key demographic variables on physical-activity behavior for a national sample of adults as well as how these relationships differ for cancer survivors and their counterparts.
Methods: Using the …

Promoting Healthier Treatment Outcomes In Obese Cancer Patients Taking High Dose Methotrexate, Carly Dell'ova
Walden Dissertations and Doctoral Studies
Cancer and obesity rates continue to rise, creating enormous public heath burdens to the individual and at the national and global levels, reducing quality of life, and increasing spending. Moreover, the relationships between cancer and obesity are not well understood. A commonly used chemotherapy for several types of cancer is high dose methotrexate (HDMTX). Along with chemotherapy, especially at high doses, comes toxicity to specific organs and the entire body. However, limited research has been conducted on obese cancer patients as they are often excluded from clinical studies. Practitioners need to better understand how to dose these patients to provide …
An Analysis Of Water Quality At Orange County, California Beaches, Naomi Meurice
An Analysis Of Water Quality At Orange County, California Beaches, Naomi Meurice
Pomona Senior Theses
Beaches in Southern California are highly recreated by residents and visitors, making beaches socially and economically important. Public health departments in coastal communities are in charge of measuring water quality and ensuring it is safe for users. Research in the past has indicated that beach water quality gets worse after storms, with bacteria levels jumping on the day of a storm and staying high for up to five days. Studies have shown these spikes in bacteria to be associated with storm runoff, with beaches closer to runoff discharge locations experiencing more impact. However, prior research has not considered the period …

Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder
Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder
Undergraduate Honors Theses
The following project involves a systematic review of the scientific literature on neural and biological changes of mothers and fathers in parenthood. Until very recently, little scientific research was devoted to studying how bearing children affects a man or woman’s long-term biology. Over the last twenty years, studies of neuroplastic changes in new mothers show specific neural mechanisms responsible for altering the behaviors of mothers during and after pregnancy. These changes in neuroplasticity alter behavior in such a way that led to mothers requiring less sleep and being more prone to hearing the cries of their children. In addition to …

Cultivating Carrots, Community, And Health-Conscious Children: Investigating The Effects Of Community Garden Implementation On Nutrition Attitudes Of Elementary Students In The Los Angeles Unified School District, Hannah Michele Tiedemann
Scripps Senior Theses
Growing up in an urban food desert can significantly affect children's development, health, and well-being (Jencks et al., 1990; Leventhal et al., 2000). Compared to their more affluent peers, youth living in low-socioeconomic urban neighborhoods are at greater risk of experiencing poor-quality diets, food insecurity, unhealthy body weights, and mental health problems (Duncan et al., 1997; Sampson et al., 1997). Moreover, children living in food-insecure households are more likely to consume calorically dense diets high in trans fat and added sugar, putting them at risk for poor health, childhood obesity, and chronic, diet-related diseases as adults (Nielsen et al., 2002). …

Statistical Methods For Gwas And The Impact Of Diabetic Medication Adherence On Healthcare Costs, Meida Wang
Dissertations, Master's Theses and Master's Reports
This dissertation includes three Chapters. In Chapter One, we develop a computationally efficient clustering linear combination approach to jointly analyze multiple phenotypes for GWAS. In this paper, based on the existing CLC method and ACAT strategy, we develop the ceCLC method to test association between multiple phenotypes and a genetic variant. In Chapter Two, we develop a novel method called sCLC for association studies of multiple phenotypes and a genetic variant based on GWAS summary statistics. Simulation results show that sCLC can control Type I error rates well and has the highest power in most scenarios. In Chapter Three, we …
Surveillance For Ticks And Tick-Borne Pathogens In Kentucky, Anna Rosalee Pasternak
Surveillance For Ticks And Tick-Borne Pathogens In Kentucky, Anna Rosalee Pasternak
Theses and Dissertations--Entomology
Tick-borne diseases are an emerging threat to human and animal health. In Kentucky, tick-borne disease surveillance has identified rising incidences of spotted fever rickettsiosis, ehrlichiosis, and Lyme disease. Since these diseases occur through the bites of infected ticks, effective prevention efforts are reliant upon knowing where the risk of exposure to tick bites exists. Historical data on tick distribution in Kentucky is variable, with very little reported on a statewide scale, leaving vector control workers, public health personnel, physicians, veterinarians, and others to rely on outdated, intermittent, or out-of-state information. In my dissertation, I surveyed ticks and select tick-borne pathogens …
