Quality Of Life: Socio-Demographic And Genetic Determinants As Well As Links With Cancer Outcomes, Jeanne Pierzynski
Quality Of Life: Socio-Demographic And Genetic Determinants As Well As Links With Cancer Outcomes, Jeanne Pierzynski
Dissertations & Theses (Open Access)
Quality of life (QOL) is an independent prognostic factor for cancer. Lung cancer is the leading cause of cancer death. Breast cancer is the most diagnosed. Bladder cancer is the most expensive cancer to treat because of its high recurrence rate. We set to perform comprehensive analyses of predictors of QOL in these cancer sites with the future goal of improving QOL and outcomes.
In 6,456 newly diagnosed lung cancer patients, we investigated the relationship between baseline patient characteristics and QOL to identify determinants of QOL. A QOL questionnaire (SF-12v1) measured patients’ physical component summary (PCS) and mental component summary …
Quantitative Analysis Of Opioids And Cannabinoids In Wastewater Samples, Alethea Jacox
Quantitative Analysis Of Opioids And Cannabinoids In Wastewater Samples, Alethea Jacox
Student Theses
Wastewater-based epidemiology is an innovative approach that uses the analysis of human excretion products in wastewater to obtain information about exposure to drugs in defined population groups. We developed and validated an analytical method for the detection and quantification of opioids (morphine, oxycodone, hydrocodone, oxymorphone and hydromorphone), and cannabinoids (9-tetrahydrocannabinol, 11-nor 9-carboxy- tetrahydrocannabinol (THCCOOH) and THCCOOH-glucuronide) in raw influent wastewater samples by ultra-high performance liquid chromatography-tandem mass spectrometry. Method validation included linearity (5–1 000 ng/L for opioids, 10–1 000 ng/L for cannabinoids), imprecision (<21.2%), accuracy (83%–131%), matrix effect (from –35.1% to –14.7%) and extraction efficiency (25%–84%), limit of detection (1–5 ng/L) and quantification (5–10 ng/L) and auto-sampler stability (no loss detected). River, sewage overflow and wastewater samples were collected in triplicate from different locations in New York City and stored at -20 C until analysis. River water samples were negative for all the compounds. Water from sewage overflow location tested positive for morphine (10.7 ng/L), oxycodone (4.2–23.5 ng/L), oxymorphone (4.8 ng/L) and hydromorphone (4.2 ng/L). Wastewater samples tested positive for morphine (133.0– 258.3 ng/L), oxycodone (31.1– 63.6 ng/L), oxymorphone (16.0–56.8 ng/L), hydromorphone (6.8–18.0 ng/L), hydrocodone (4.0– 12.8 ng/L) and THCCOOH (168.2– 772.0 ng/L). This method is sensitive and specific for opioids and marijuana determination in wastewater samples.
Epigenetic Modifications Of Human Placenta Associated With Preterm Birth, Drissa Toure
Epigenetic Modifications Of Human Placenta Associated With Preterm Birth, Drissa Toure
Theses & Dissertations
Preterm birth is a complex multifactorial process. Despite the well-known role of the placenta in supporting the fetal development and maternal-fetal tolerance, the placental epigenetic modifications and preterm birth (PTB) remains poorly understood and under investigated. Various maternal and environment factors can influence epigenetic programming during fetal development to affect the functioning and structures of organs, including the placenta, which can lead to adverse pregnancy outcomes, including PTB. The understanding of the placental epigenetic alterations and maternal determinants associated with PTB are apparently indispensable for the development of actual diagnosis and methods of prevention and treatment of premature labor. The …
Determining The Effects Of Social Media Monitoring To Identify Potential Foodborne Illness In Southern Nevada, Lauren Diprete
Determining The Effects Of Social Media Monitoring To Identify Potential Foodborne Illness In Southern Nevada, Lauren Diprete
UNLV Theses, Dissertations, Professional Papers, and Capstones
Foodborne illness, commonly referred to as food poisoning, affects an estimated 1 in 6 Americans every year, despite the fact that it is entirely preventable. Many cases of foodborne illness go unreported; however, better reporting leads to faster health department response and containment. Social media monitoring, using software to identify trends in social media posts, is a novel new tool that has been tested in a variety of public health fields with promising preliminary results. The Southern Nevada Health District (SNHD) has employed social media monitoring software to identify potential foodborne illness within Southern Nevada. The purpose of this study …
Communicating Through A Brain-Computer Interface: Towards The Assessment Of Quality Of Life In Minimally Conscious And Covertly Aware Vegetative State Patients, Jasmine Tung
Electronic Thesis and Dissertation Repository
Neuroimaging has been utilized to establish communication, using a brain-computer interface, with select patients with severe brain injuries and profound communication impairments. Due to the severe injuries sustained by these patients, traditional techniques used to develop quality of life instruments cannot be used. The Aware Study used a novel approach to establish the key dimensions for assessing the quality of life of patients who can only communicate using this sophisticated technology. Consensus methodology was employed, with the assistance of a multidisciplinary panel of experts, to collectively decide which dimensions are essential for the inclusion in a quality of life instrument …
Physical Activity, Body Mass Index, And Clustered Metabolic Risk In U.S. Adolescents: 2007-2012 Nhanes., Bethany Dawn Williams
Physical Activity, Body Mass Index, And Clustered Metabolic Risk In U.S. Adolescents: 2007-2012 Nhanes., Bethany Dawn Williams
UNF Graduate Theses and Dissertations
Objectives: To examine variation in clustered metabolic risk (cMetS) in adolescents classified as not overweight/active (NOA), not overweight/not active (NONA), overweight/active (OA), and overweight/not active (ONA).
Background: While studies to date have shown that children and adolescents who meet the current physical activity (PA) recommendations and maintain a healthy body weight demonstrate significantly lower cardiometabolic risk, there are some studies that suggest the relationship between PA and metabolic risk may be mediated by adiposity.
Methods: The sample included adolescent participants (n=875; 12-17 years) of the 2007-2012 National Health and Nutrition Examination Survey (NHANES). The cMetS score included triglycerides, high-density lipoprotein …

Statistical Analyses To Detect And Refine Genetic Associations With Neurodegenerative Diseases, Yuriko Katsumata
Theses and Dissertations--Epidemiology and Biostatistics
Dementia is a clinical state caused by neurodegeneration and characterized by a loss of function in cognitive domains and behavior. Alzheimer’s disease (AD) is the most common form of dementia. Although the amyloid β (Aβ) protein and hyperphosphorylated tau aggregates in the brain are considered to be the key pathological hallmarks of AD, the exact cause of AD is yet to be identified. In addition, clinical diagnoses of AD can be error prone. Many previous studies have compared the clinical diagnosis of AD against the gold standard of autopsy confirmation and shown substantial AD misdiagnosis Hippocampal sclerosis of aging (HS-Aging) …
The Association Between Dietary Flavonoid Intake And Chronic Obstructive Pulmonary Disease, Systemic Inflammation, And Comorbidity Burden, Tennador Sanderson
The Association Between Dietary Flavonoid Intake And Chronic Obstructive Pulmonary Disease, Systemic Inflammation, And Comorbidity Burden, Tennador Sanderson
Walden Dissertations and Doctoral Studies
Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in the United States. Dietary habits may have an impact on COPD through anti-inflammatory mechanisms. For this cross-sectional secondary data analysis study, the advanced model of the epidemiology triangle was used as a guide to assess the association between total daily flavonoid intake and COPD diagnosis, COPD severity, systemic inflammation, and comorbidity burden. Data from over 5,100 male and female participants aged 30 and older were obtained from the 2007-2010 National Health and Nutrition Examination Survey. The prevalence of COPD was 5.2% according to spirometry data. Multiple …

The Cardiovascular Epidemiology And Genome-Wide Associations Of Biomarkers Of Innate And Adaptive Immunity: Scd163 And Sil2ra, Jon Peter Durda
Graduate College Dissertations and Theses
Cardiovascular disease (CVD) is a major cause of morbidity and mortality in the U.S. and worldwide. Atherosclerosis, the buildup of plaque in the arteries, is a common cause of CVD. For many years, research in atherosclerosis was focused on lipid metabolism and the accumulation of low-density lipoprotein in the arteries. While this research set public health guidelines for lipid management, lipid concentration was not the only factor influencing atherosclerosis and CVD events. Many scientists, as far back as the 1850’s recognized the role of inflammation in the progression of atherosclerotic disease. The continuous low levels of immune activation in the …
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Williams Honors College, Honors Research Projects
Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.
Objectives: To evaluate the use of biomarkers in children seen in the Emergency …
Drinking Motives Underlying Internalizing And Externalizing Pathways To Alcohol Misuse In College Students, Jeanne Savage
Drinking Motives Underlying Internalizing And Externalizing Pathways To Alcohol Misuse In College Students, Jeanne Savage
Theses and Dissertations
Alcohol misuse, including heavy episodic use and negative consequences, is a major public health concern and a particular problem among college students. The etiology of alcohol misuse is not well resolved, with multiple and often contradictory factors implicated in its development. Genetic factors influence alcohol misuse but few specific genes have been identified. A potential reason for these challenges is that alcohol misuse is phenotypically and genetically heterogeneous; that is, there are multiple causal pathways underlying its development. Previous typologies have suggested that distinct internalizing and externalizing pathways are involved, with corresponding differences in profiles of personality, temperament, and comorbid …
