Emergency Medical Service Worker Knowledge Of And Compliance With Occupational Exposures To Infectious Diseases, Debra Ann Wrentz-Hudson

Walden Dissertations and Doctoral Studies

Firefighter Emergency Medical Service (EMS) responder personnel are at a high risk for occupational exposures to bloodborne and airborne infectious pathogens due to their unpredictable work duties in the pre-hospital environment. Not much is known about the compliance with Universal Precautions (UP) among firefighter EMS responders' personnel with regards to occupational exposures to infectious diseases. The purpose of this cross-sectional research study was to determine the relationship between compliance with UP, knowledge of UP, attitudes towards UP, occupational practices, and occupational exposures to bloodborne and airborne pathogens to prevent transmission of infectious disease among firefighter EMS responder personnel in the …

Food Security Status And Life Events Among Households With Children In The Midlands Of South Carolina, Erin Rebekah Drucker

Theses and Dissertations

Purpose: Food insecurity is a major public health problem in the United States (US) with 14.5% of US households having experienced some level of food insecurity in 2012. Among households with children, 20% experienced low food security in 2012, and in half of these households, both the children and adults were affected. Food insecurity among children can have lifelong negative health and mental effects. Life events are defined as self-­‐reported life changes, which create a strain on resources and an opportunity for food insecurity, Methods: The Midlands Family Study (MFS) was a cross-­‐ sectional study that surveyed households …

Evolution In Action: Climate Change, Biodiversity Dynamics And Emerging Infectious Disease, Eric P. Hoberg, Daniel R. Brooks

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Climatological variation and ecological perturbation have been pervasive drivers of faunal assembly, structure and diversification for parasites and pathogens through recurrent events of geographical and host colonization at varying spatial and temporal scales of Earth history. Episodic shifts in climate and environmental settings, in conjunction with ecological mechanisms and host switching, are often critical determinants of parasite diversification, a view counter to more than a century of coevolutionary thinking about the nature of complex host–parasite assemblages. Parasites are resource specialists with restricted host ranges, yet shifts onto relatively unrelated hosts are common during phylogenetic diversification of parasite lineages and directly …

Uric Acid Level Is Associated With Postprandial Lipemic Response To A High Saturated Fat Meal, Roy Gail Cutler

Walden Dissertations and Doctoral Studies

Hyperlipidemia caused by a diet high in saturated fat can lead to visceral fat weight gain, obesity, and metabolic syndrome. Being over-weight from visceral fat has been linked to increased risk of developing most age-related diseases and disability, along with a lower income potential and quality of life. However, researchers are just beginning to understand the biological mechanisms that regulate the conversion of excess calories into visceral fat storage rather than glycogen or muscle. Epidemiological studies have repeatedly shown a comorbid association between age-related diseases involving hyperlipemia and circulating levels of uric acid, but not a direct association. This study …

Walden Dissertations and Doctoral Studies

Catheter associated urinary tract infection (CAUTI) incidence continue to rise despite all prevention efforts. The state of Georgia incidence of CAUTI between 2012 and 2013 showed an increase by 350 cases. The challenge is translating CAUTI prevention knowledge into practice by all physicians. The purpose of this correlational study was to improve the epidemiological understanding of CAUTI. Looking at physicians’ perception and practice of CAUTI preventions was necessary. A total of 336 physicians from the state of Georgia completed a 26-item survey. Additionally, a pilot study was conducted on a small sample of participants. The result of the Cronbach alpha …

Effect Of Placard Grading On Food Safety In Retail Food Facilities, Christopher Ogbonna Ogbu

Walden Dissertations and Doctoral Studies

Most people have had an episode of foodborne illness at one time or another; however, the majority of those stricken with foodborne illness fails to associate ill health with something consumed within the past 72 hours. The World Health Organization (WHO) estimates that foodborne diseases affect 30% of the population in developed countries, and that in developing countries, about 2 million people die yearly due to foodborne illness. Previous researchers have indicated that food handlers with poor personal hygiene are potential sources of infection. Although public health agencies in many countries already regularly inspect food facilities to control potential foodborne …

U.S. Army Enlisted Soldiers' Adherence To Prescribed Malaria Chemoprophylaxis In Afghanistan, Michael Paul Brisson

Walden Dissertations and Doctoral Studies

Over the past 13 years, the United States Army has been engaged in armed conflict within Afghanistan. Unfortunately, the United States Army has been forced to evacuate soldiers from the battlefield because of malaria, a parasitic disease that is endemic in Afghanistan. Even though the U.S. Army has adopted an effective chemoprophylaxis protocol, soldiers' adherence to their prescribed medication has been historically low. This research addressed a gap in literature regarding the adherence rates of U.S. Army enlisted soldiers to their prescribed oral malaria chemoprophylaxis. In addition, this research investigated self-reported reasons for soldiers' nonadherence to this medication. The study …

Investigating The Effect Of Arsenic On Chromium(Vi)-Induced Genotoxicity In Human Lung Fibroblasts, Jason Stewart Ms

All Student Scholarship

Hexavalent chromium (Cr(VI)) compounds are well-established human lung carcinogens. Arsenic (As) is a well documented human carcinogen with long term exposure to AS in drinking water being linked to lung, kidney and liver cancer, among others. Co-exposure studies are now becoming more common as humans are not exposed to just one toxicant at a time. This is the first study to investigate the effects of co-exposure with arsenic and soluble or particulate Cr(Vi) compounds in human lung fibroblasts.

Social Determinants Of Health Inequality And Life Expectancy Among Women Of Edo State, Nigeria, Daniel Aromeh Odekina

Walden Dissertations and Doctoral Studies

Health inequality conflates a huge number of economic, social, and political issues. These issues, together described as social determinants, determine a population's health through influencing health status and life expectancy. The research purpose of this study was to examine how social determinants affected the life expectancy of the women of Edo State, based on secondary data from Nigeria's 2008 demographic and health survey (NDHS). The theories that guided the study were self-efficacy beliefs of the social cognitive theory and physical self-concept of the health belief model. This quantitative cross-sectional study examined the associations between socioeconomic status, nutritional status, literacy/educational attainment, …

Impact Of Goodwill Organizations And Community Collaboration On Aids-Orphans' Needs In Nyanza Province, Kenya, Anthonia Nwagbo

Walden Dissertations and Doctoral Studies

A number of researchers have explored the toll of AIDS on the children who have become orphans as a result of the disease; others have investigated the roles of aid-giving agencies on the alleviation of the orphans' situation. However, despite researchers' pointing to the germaneness of community and goodwill agency liaison, no study had examined the impact of such collaboration on the resources available to the orphans. To this end, the heads-of-household of 532 AIDS orphans under 18 years old in Kenya's Nyanza province were surveyed to investigate the impact of community-referral on the state of AIDS orphans with regard …

Mining And Hiv/Aids Transmission Among Marampa Mining Communities In Lunsar, Sierra Leone, Alphajoh Cham

Walden Dissertations and Doctoral Studies

Since the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) was first reported in Sierra Leone in 1987, its prevalence rate has stabilized at 1.5% in the nation's general population. However, concerns exist regarding the potential increase in high-risk populations, particularly among mineworkers and commercial sex workers. The potential spread of HIV/AIDS as a result of labor migration may threaten the mining sector, which has been identified as a critical driver of recent economic growth and development. A gap remains in the literature regarding the contextual factors in mining communities that lead to high rates of HIV/AIDS. Therefore, the purpose of …

Using a quantitative approach to examine a variety of social variables aligning with the ecological framework, …

Differentiating Demographic Factors In Latino Patients With Type 2 Diabetes, Carol Lynne Manning

Walden Dissertations and Doctoral Studies

The American Diabetes Association (ADA) data suggest that Latinos share a greater burden of disease than do non-Latino Whites with type 2 diabetes. As a result of poor glycemic control, Latinos also suffer consequences such as blindness, kidney disease, and limb amputation more often than do other ethnic groups. The purpose of this study was to compare demographic factors of Latinos with well-controlled type 2 diabetes, as measured by a HgbA1c of 7 or less (n = 118) to Latinos not well controlled (n = 105). This cross sectional study used a secondary data set with a sample selected from …

Albumin Levels In Hispanic Dialysis Patients With And Without Type Ii Diabetes, Hector Hernandez

Walden Dissertations and Doctoral Studies

Albumin provides the vital scaffolding for growth and tissue repair and supports oncotic blood pressure and hemodynamics. In hemodialysis patients, albumin aids with fluid removal by drawing excess fluid from edematous tissues back into the blood where it can then be removed by a dialyzer. The hyperglycemia seen in dialysis patients with Type II diabetes progressively damages kidney glomeruli, which permits albumin seepage into the urine, thus lowering serum albumin. The conceptual framework underpinning this research is the van't Hoff theory of osmotic pressure. Under this framework, the solute-solvent relationship largely contributes to the osmotic movement of fluid. The purpose …
