Effectiveness Of Earthtec ® On Killing Invasive Quagga Mussels (Dreissena Rostriformis Bugenis) And Preventing Their Colonization In The Western U.S., Ashlie Watters

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dreissena rostriformis bugensis, an invasive species, also known as the quagga mussel, was discovered in Lake Mead, NV in January of 2007. In the four years since detection, quagga mussels have created tremendous economical, ecological, and human health impacts. The mussels clog pipes, ruin boat motors, and damage recreational equipment, and once established in the lake, routine maintenance is necessary to avoid further damage. Because of quagga mussels' high fecundity, planktonic veliger stage, and ability to attach to substrates with byssal threads, they have easily and swiftly spread to other lakes and reservoirs in the Lower Colorado River Basin. …

Exploring Geographic Proximity To Fast-Food Restaurants And Convenience Stores With Dental Caries In Patients At The University Of Nevada Las Vegas School Of Dental Medicine, Charles K. Hill

UNLV Theses, Dissertations, Professional Papers, and Capstones

Dental caries is present worldwide and has afflicted over 90% of all adults in the United States. Biological determinants of the disease are well understood but social determinants and how they interact with biological factors are not. Programs designed to reduce incidence and prevalence of caries often target certain individuals and involve behavioral change. Some programs are more successful when environmental and societal issues are also addressed (Watt, 2002). Biological and behavioral processes leading to caries should include the modification of social factors to enhance results of prevention programs designed to reduce caries in populations. Preventing disease comes not only …

Analysis Of Ghrelin Concentrations In Serum Samples Processed At One, Two, And Three Hours After Collection, Christine E. Prato

UNLV Theses, Dissertations, Professional Papers, and Capstones

Obesity is becoming an epidemic of modern society. While the health-related consequences of obesity have been well studied, scientists continue to search for biological risk factors associated with this disease. Since the 1999 discovery of an appetite-stimulating hormone, ghrelin, researchers have further questioned the physiological interactions that lead to obesity. The fundus of the stomach, as well as the intestines and kidneys produce ghrelin before it circulates throughout the body and attaches to its receptor sites located within the section of the brain responsible for appetite-regulation. The hormone increases and decreases in a circadian rhythm that may dictate the routine …

High-Risk Human Papillomavirus (Hpv): An Emerging Health Issue For Women And Minorities, Dierdre O. Turner

UNLV Theses, Dissertations, Professional Papers, and Capstones

The human papillomavirus (HPV) is the cause of nearly all cases of cervical cancers worldwide. HPV viral DNA is found in more than 99% of cervical cancers. In addition to cervical cancer, HPV is also associated with some breast and oral cancers. White women have been showing a decline in breast cancer rates while black women are continuously showing higher rates of mortality from both breast and cervical cancer. Minority women are also more likely to receive a late diagnosis and are showing increased incidence of oral cancer, which makes study of HPV in women and minorities significant.

The Development And Evaluation Of A Safety Skill Intervention For Child Victims Of Neglect, Heather H. Hill

UNLV Theses, Dissertations, Professional Papers, and Capstones

Child neglect is the least studied, yet most frequently indicated, type of child maltreatment. Still, there are few assessment and treatment methods specifically designed for victims of child neglect. Unintentional injuries have long remained the leading cause of death for children in the United States after the first year of life, and research suggests the majority of these child fatalities are actually the result of child neglect. Homes of neglectful families are often inundated with safety hazards but child-focused home safety skill interventions have yet to be developed. Thus, the present study focused on the development and initial evaluation of …

Lead Concentrations In Extracted Primary Teeth Among Clark County Pediatric Patients, Jennifer A. Berger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Childhood lead poisoning is a completely preventable condition, yet only a small portion of children in Nevada are screened for elevated blood lead levels. In 2009 only 6.11 percent of children in Nevada were screened for lead indicating that Nevada would benefit from an alternative method of screening for childhood lead exposure. Deciduous teeth are not currently recognized by the Centers for Disease Control and Prevention as diagnostic samples for the measurement for lead exposure. However, this unique and innovative detection method utilizes opportunistic samples that will contribute to the childhood lead poisoning prevention efforts in Nevada.

The purpose of this research project was to identify potential predictors of juvenile firesetting behavior by studying youth who were enrolled in a regional firesetting intervention program. Data collected from firesetting assessment instruments completed by parents or guardians of program participants were examined. In the analyses, special emphasis was placed on evaluating associations between juvenile firesetting behavior and the socioeconomic …

Identifying And Reducing Lead Exposure Associated With The Use Of Cultural Practices In Southern Nevada Hispanic Communities, Maria Castillo-Couch

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite large amounts of national data on lead and childhood lead poisoning, the status of childhood lead exposure in Nevada as a result of the use of cultural practices in the Hispanic population is unknown. The influx of immigrant Hispanic populations to Nevada, their low education level, the high number of them who are living in poverty present an increased risk for children to be exposed to lead through the use of imported consumables, home remedies and alternative medicine (i.e., healers/ sobadores).

A 61-question survey collected data from Hispanics over 18 years of age who have or take care …

Effects Of Environment On Children's Motor Scores, Eligibility Status, And Administration Times, Derrick Mittelstadt, Abigail Parker, Kirsten Pickett, Heather Temkin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Best practices for assessing developmental skills in young children focus on naturalistic observation in everyday settings, but the effects of environment on test scores, eligibility status and administration time have not been explored. The Peabody Developmental Motor Scales-Second Edition (PDMS-2) was administered to 34 children aged 18 to 59 months in natural and pull-out settings. PDMS-2 total, gross, and fine motor quotient (TMQ, GMQ, and FMQ) scores were significantly lower in the natural environment (p’s≤.014). Based on our results, more children would qualify for services when tested in natural environments using TMQ and GMQ scores. It also took significantly longer …

Self-Reported Exercise And Risk Of Osteoporosis In Prostate Cancer Patients Receiving Androgen Deprivation Therapy, Lori J. Mennen-Winchell

Loma Linda University Electronic Theses, Dissertations & Projects

Prostate cancer is stimulated to grow in response to testosterone. Androgen deprivation therapy (ADT) leads to chemical castration and suppression of prostate cancer cell production. Testosterone levels less then 300ng/ml decreases bone mineral density and could result in osteoporosis. Studies have shown that during the first year of ADT, fracture risk, mainly in hips and spine increases about 50%. In men, 40% of hip fractures result in death. Exercise may reduce the risk of osteoporosis and thus contribute to the prevention of hip and other fractures. There is limited data regarding whether exercise is associated with a reduced risk of …

Use Of Audit, And Measures Of Drinking Frequency And Patterns To Detect Associations Between Alcohol And Sexual Behaviour In Male Sex Workers In Kenya, Stanley Luchters, Scott Geibel, Masila Syengo, Daniel Lango, Nzioki King'ola, Marleen Temmerman, Matthew F. Chersich

Population Health, East Africa

Background: Previous research has linked alcohol use with an increased number of sexual partners, inconsistent condom use and a raised incidence of sexually transmitted infections (STIs). However, alcohol measures have been poorly standardised, with many ill-suited to eliciting, with adequate precision, the relationship between alcohol use and sexual risk behaviour. This study investigates which alcohol indicator - single-item measures of frequency and patterns of drinking ( > = 6 drinks on 1 occasion), or the Alcohol Use Disorders Identification Test (AUDIT) - can detect associations between alcohol use and unsafe sexual behaviour among male sex workers.

Methods: A cross-sectional …

Youth At The Nexus: Ideology In Hiv Prevention In Nairobi, Kenya, Zohra Ahmed

Scholarly Works

In the fight against HIV/AIDS, the Behavior Change Communication (BCC) model stands as international best practice in preventive education. Ideally, a BCC intervention aims to changes behaviors and attitudes by facilitating group negotiation and introspection, with a resultant improvement in health. However, introducing this best practice model to a group of youth in Nairobi resulted in suboptimal outcomes: they were unaccustomed to expressing themselves in the ways prescribed by the class. To explain this failure, I examine how local discourses produced by parents and teachers communicate agency, sexuality and health, and highlight the diverging practices invoked at home, school and …

Analysis Of Out-Of-Pocket Expenditures Of Oral Oncologics For Tennessee Recipients Of Medicare Part D, Eve Carolyn Elias

Theses and Dissertations (ETD)

Background: There are few studies that examine patients' costs of oral oncology drugs from Medicare Part D plan providers. These drugs can impose a financial burden to beneficiaries, and, due to their cost, place beneficiaries in the coverage gap in a short period of time. In addition to examining costs, there is little published concerning the potential impact of drug utilization management techniques on access to these drugs in Medicare Part D plans. This study examined the roles of prior authorization, step-therapy, and placement of drugs in higher formulary tiers on patients' out-of-pocket costs, and access to therapy.

Radiation Therapy Treatment Plan Optimization Accounting For Random And Systematic Patient Setup Uncertainties, Joseph Moore

Theses and Dissertations

External-beam radiotherapy is one of the primary methods for treating cancer. Typically a radiotherapy treatment course consists of radiation delivered to the patient in multiple daily treatment fractions over 6-8 weeks. Each fraction requires the patient to be aligned with the image acquired before the treatment course used in treatment planning. Unfortunately, patient alignment is not perfect and results in residual errors in patient setup. The standard technique for dealing with errors in patient setup is to expand the volume of the target by some margin to ensure the target receives the planned dose in the presence of setup errors. …

Exploring Student Perceptions To Explain The Relationship Between Physical Activity And Academic Achievement In Adolescents: A Mixed Methods Study, Megan J. Hylok

College of Education and Human Sciences: Dissertations, Theses, and Student Research

A nationwide survey conducted by the Center for Disease Control in 2007 reported 65% of high school students did not meet the recommendation that youth participate in at least 60 minutes of physical activity most days of the week (CDC, 2008). While research has focused its attention primarily on bodily health, growing evidence supports the benefits of physical activity on brain health (Ratey & Hagerman, 2008). Physical activity is important and many adolescents are not meeting the recommendation, therefore, it is important to explore the adolescent perceptions to understand which factors influence physical activity participation. The significance of this study …

Effect Of Routine Iron Supplementation With Or Without Folic Acid On Anemia During Pregnancy, Mohammad Yawar Yakoob, Zulfiqar Ahmed Bhutta

Woman and Child Health

Introduction:Iron deficiency is the most prevalent nutrient deficiency in the world, particularly during pregnancy. According to the literature, anemia, particularly severe anemia, is associated with increased risk of maternal mortality. It also puts mothers at risk of multiple perinatal complications. Numerous studies in the past have evaluated the impact of supplementation with iron and iron-folate but data regarding the efficacy and quality of evidence of these interventions are lacking. This article aims to address the impact of iron with and without folate supplementation on maternal anemia and provides outcome specific quality according to the Child Health Epidemiology Reference Group …

Effect Of Multiple Micronutrient Supplementation During Pregnancy On Maternal And Birth Outcomes, Batool Azra Haider, Mohammad Yawar Yakoob, Zulfiqar Ahmed Bhutta

Woman and Child Health

Objectives/Background:Given the widespread prevalence of micronutrient deficiencies in developing countries, supplementation with multiple micronutrients rather than iron-folate alone, could be of potential benefit to the mother and the fetus. These benefits could relate to prevention of maternal complications and reduction in other adverse pregnancy outcomes such as small-for-gestational age (SGA) births, low birth weight, stillbirths, perinatal and neonatal mortality. This review evaluates the evidence of the impact of multiple micronutrient supplements during pregnancy, in comparison with standard iron-folate supplements, on specific maternal and pregnancy outcomes of relevance to the Lives Saved Tool (LiST). Data sources/review methods: A systematic review …

Background: Of 136 million babies born annually, around 10 million require assistance to breathe. Each year 814,000 neonatal deaths result from intrapartum-related events in term babies (previously "birth asphyxia") and 1.03 million from complications of prematurity. No systematic assessment of mortality reduction from tactile stimulation or resuscitation has been published. Objective:To estimate the mortality effect of immediate newborn assessment and stimulation, and basic resuscitation on neonatal deaths due to term intrapartum-related events or preterm birth, for facility and home births.

Methods:

We conducted systematic reviews for studies reporting relevant mortality or morbidity outcomes. Evidence was assessed using GRADE criteria …

The Effect Of Folic Acid, Protein Energy And Multiple Micronutrient Supplements In Pregnancy On Stillbirths, Aamer Imdad, Mohammad Yawar Yakoob, Zulfiqar Ahmed Bhutta

Woman and Child Health

Background:Pregnancy is a state of increased requirement of macro-and micronutrients, and malnourishment or inadequate dietary intake before and during pregnancy, can lead to adverse perinatal outcomes including stillbirths. Many nutritional interventions have been proposed during pregnancy according to the nutritional status of the mother and baseline risk factors for different gestational disorders. In this paper, we have reviewed three nutritional interventions including peri-conceptional folic acid supplementation, balanced protein energy supplementation and multiple micronutrients supplementation during pregnancy. This paper is a part of a series to estimate the effect of interventions on stillbirths for input to Live Saved Tool (LiST) …

Youth Dating Culture In Urban Vietnam: Attitudes, Behaviors, And Influences, Alexa Difiore

Independent Study Project (ISP) Collection

This paper attempts to research urban youth’s attitudes and behaviors concerning everything having to do with dating (the process, PDA, typical dating spots and behavior) and opinions towards “hot issues” in contemporary, Vietnam such as pre-marital sex and co-habitation. My research question focuses on what the term “dating” means among youth in urban Vietnam, and the various influences that affect youth’s dating and sexual lives. Through an extensive literature review, I learned that there is an overall lack of information and discussion about sex in Vietnam. There is also a general idea that from parents, the government, and school that …
