Nanotechnology is regarded as one of the key technologies of the future and associated with high expectations by politics, science and economy. Artificially produced nanosized particles and nanoscale system components have new properties which are of importance for the development of new products and applications. Such new properties of materials and substances result from the special properties of surfaces and interfaces and in part, from the geometric shape of the material. In theory nanoparticles (NPs) can be produced from nearly any chemical; however, most NPs that are currently in use today have been made from transition metals, silicon, carbon (single-walled …

Separation And Characterization Of Respirable Amphibole Fibers From Libby, Montana, James S. Webber, David J. Blake, Tony Ward, Jean C. Pfau

Public and Community Health Sciences Faculty Publications

The vermiculite mine in Libby, Montana, was in operation for over 70 yr and was contaminated with asbestos-like amphibole fibers. The mining, processing, and shipping of this vermiculite led to significant fiber inhalation exposure throughout the community, and residents of Libby have developed numerous pulmonary diseases such as lung cancer and mesothelioma. The present study describes the separation of Libby 6-mix into respirable and nonrespirable size fractions by means of aqueous elutriation. The elutriator, designed to separate fibers with aerodynamic diameters smaller than 2.5 μm (respirable) from larger fibers, used an upward flow rate of 3.4 × 10^{−4 …}

Nationwide secondary data was extracted from the 2002 Core Social Welfare Indicators Survey and the National Health Services Statistics databases obtained from National Statistics of Malawi. The National Health Facilities inventory obtained from the Malawi diffusion project was also geocoded to display the distribution of health care facilities in the country. Spatial autocorrelation and regression modeling techniques were applied on the national representative data set.

The spatial autocorrelation test revealed …

Hiv Risk Among Nursing Students In Rwanda : Self-Efficacy, Knowledge And Attitudes, Jacqueline Wosinski

Loma Linda University Electronic Theses, Dissertations & Projects

Acquired immune deficiency syndrome (AIDS) is the leading cause of death in sub-Saharan Africa. With a prevalence rate of 3.1% in 2006, Rwanda is one of the hardest hit countries. Nurses are often the leading health professionals in rural communities and at the forefront of the fight against the HIV pandemic. Little has been written on how nurses are prepared to intervene successfully along the continuum of HIV prevention and care. A mixed-methods sequential exploratory approach was used to explore this question.

In the first phase, cognitive, socio-psychological, and environmental factors of nursing education in Rwanda in regard to HIV …

Partner Communication And Factors Associated With The Decision To Obtain An Hiv Test Among Chinese/Chinese American Community College Students In Northern California, Sang Leng Trieu

Loma Linda University Electronic Theses, Dissertations & Projects

HIV testing and counseling is considered the cornerstone of a comprehensive approach to HIV prevention and education. Little is known, however, about HIV prevention, including HIV testing rates for Asian Pacific Islander (API) women, because data for this ethnic group is aggregated, thus limiting specific data for Chinese/Chinese American population or other API subgroups. This dissertation research examined factors associated with the decision to obtain an HIV test among Chinese/Chinese American community college women and explored the association among relationship status, partnership communication, and discussions of HIV testing.

Using constructs of the health belief model, an online and paper-pencil, crosssectional …

An overall health outcome was measured using height, weight, grip strength and BMI, and the speech acceptability was measured using a “Universal …

The Changing Role Of Physicians In Disaster Management And Hospital Incident Command, F. Matthew Mihelic, M. David Stockton, Stephen A. Cole, Gregory H. Blake

Faculty Publications

Recent changes in governmental policy toward disaster medicine and hospital incident command foreshadow a significant change in the role that physicians will play in disaster preparedness and response. The distinct discipline of Disaster Medicine has received authoritative recognition and promotion in the recent Homeland Security Presidential Directive 21, and recently established guidelines for incident command within hospitals have included a new position designated as “Medical/Technical Specialist(s)” that will assist the Incident Commander in disaster-related decision-making. This is a multidisciplinary position, and its functions can be filled by one or more individuals. As physician training and competency in Disaster Medicine increases, …

Socioeconomic Determinants Of Hiv Status In Kenya, Kimberly Fletcher

Masters Theses & Specialist Projects

The spread of Human Immunodeficiency Virus (HIV) is one of the greatest threats to stability and development in Kenya. The country's infection rate is estimated between seven and eight percent, making it one of the highest in the world. Several studies have been done that examine subpopulations such as truck drivers, sex workers, and migrants. However, to date there is little research that examines who, across the country, is contracting HIV. Kenya's 2003 Demographic and Health Survey includes data that make it possible to determine which groups have the highest odds of being infected. The question of who is contracting …

Self-Efficacy, Physical Activity, And Aerobic Fitness In Middle School Children: Examination Of A Pedometer Intervention Program, Dana M. Manley

Theses and Dissertations (ETD)

The purpose of this study was to examine the relationships among self-efficacy levels, physical activity, aerobic fitness, and body composition (relative body mass index; RBMI) and to determine whether a school-based pedometer intervention program would improve those variables and prevent weight gain in sixth and seventh graders in rural mid-South middle schools. Bandura’s Social Cognitive Theory served as the theoretical basis for the study.Methods: A quasi-experimental pre-test, post-test design was used. The sample, recruited from two rural middle schools in Kentucky, consisted of 116 sixth and seventh grade students (98% Caucasian, 51% male, age=11.65±0.71). Anthropometric assessment of height, weight, …

Sex Education In Amsterdam: What They Do And Why They Choose To Do It., Coral E. Hackler

Independent Study Project (ISP) Collection

Sex education in the Netherlands has been regarded by many as exemplary. Around the world the phrase “Double Dutch” is known as the term of using both the condom and the pill. The actual effectiveness of sexuality education in the Netherlands has rarely been studied. The teachers themselves must decide what they believe will be the most effective methods of sexuality education. This begs one to question why a teacher chooses the methods they have chosen and what makes them believe that these methods are effective. Because there is no research on how sexuality education is directly influencing students, teachers …

The Complexity Of Re-Evaluating Antiretroviral Therapy Eligibility Guidelines For Hiv/Aids Patients In Uganda, Jennifer Klein

Independent Study Project (ISP) Collection

When I first learned that the eligibility criteria for Antiretroviral Drugs (ARVs) in Uganda is to have a CD4 cell count of 200 or below, I was shocked. Actually, I think my exact response was, “So patients must have full-blown AIDS, severely weakened immune systems, and may be on their deathbeds before they can receive the drugs?” I knew little of the subject, other than that in the United States HIV-positive patients who are on drugs may avoid many of the opportunistic infections and complications that come from delaying treatment until the CD4 count is low. My initial confusion over …

Give Life Without Losing Life: The Casa Materna Of Matagalpa And The Struggle To Prevent Maternal Death, Lily Emiko Friedman

Independent Study Project (ISP) Collection

Maternal mortality has a face. It is the health indicator with the greatest disparity between the developed and developing worlds, disproportionately affecting poor women with low levels of education, high levels of fertility, and inadequate access to health services. It is the health inequality that most clearly shows how poor health outcomes continue to be directly linked to poverty and socioeconomic disadvantage, while the right to safe pregnancy and motherhood comes with economic privilege. As it occupies such a critical position in community health, maternal mortality has been widely studied and the target of countless health interventions aimed at its …

Systems Biology: The Solution To Understanding Alcohol-Induced Disorders?, National Institute On Alcohol Abuse And Alcoholism

United States Public Health Resources

With the decoding of the human genome, researchers gained access to extensive information about the molecules in the body, how they function in the healthy organism, and how they may contribute to certain diseases. However, despite this wealth of information, many questions remain about the ways in which these molecules interact to control more complex phenomena, including the development of many common disorders. Systems biology offers scientists a promising tool with which to deal with such complexities and may revolutionize the prognosis, diagnosis, and treatment of alcohol use disorders and other multifaceted disorders. These new approaches provide researchers with new …

Methods: We studied a historical cohort of women who had a singleton live birth in the years 2000-2002, from a semirural area of Pakistan. Infant's birth weight was obtained from records, and prenatal records had data for …

An Overview Of Observational Sleep Research With Application To Sleep Stage Transitioning, Brian S. Caffo, B. Swihart, A. Laffan, C. Crainiceanu, N. Punjabi

Johns Hopkins University, Dept. of Biostatistics Working Papers

In this manuscript we give an overview of observational sleep research with a particular emphasis on sleep stage transitions. Sleep states represent a categorization of sleep electroencephalogram behavior over the night. We postulate that the rate of transitioning between sleep states is an important predictor of health. This claim is evaluated by comparing subjects with sleep disordered breathing to matched controls.

Targeted Methods For Biomarker Discovery, The Search For A Standard, Catherine Tuglus, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

More often than not biomarker studies analyze large quantities of variables with complicated and generally unknown correlation structure. There are numerous statistical methods which attempt to unravel these variables and determine the underlying mechanism through identification of causally related biomarkers. Results from these methods are generally difficult to interpret and nearly impossible to compare across studies. The FDA has currently called for a standardization of methods and protocol for biomarker detection. In response, we propose targeted variable importance (tVIM) as a standardized method for biomarker discovery. Through the use of targeted Maximum Likelihood, tVIM provides double robust estimates of variable …

In Vitro Toxicity Of Aluminum Nanoparticles In Human Keratinocytes, Stephanie Mccormack-Brown

Theses and Dissertations

Nanotechnology promises to be the defining technology of the 21st century. At an annual investment of $1B, it provides significant contributions to manufacturing, medicine, energy conservation, and the environment. Nanoparticles are structures with at least one dimension in the 1 to 100 nanometer (nm) range. DoD and US Air Force interest in aluminum nanoparticles (AL NPs) stems from its ability to enhance combustion jet fuel, thus increasing fuel efficiency. The addition of AL NPs to JP-8 may pose a unique dermal hazard to aircraft maintenance workers. There is no published data on AL NP toxicity effects on human skin. This …

Basis For Treatment Of Tuberculosis Among Hiv-Infected Patients In Tanzania: The Role Of Chest X-Ray And Sputum Culture, Muhammad Bakari, Robert D. Arbeit, Lillian Mtei, Johnson Lyimo, Richard Waddell, Mecky Matee, Bernard F. Cole, Susan Tvaroha

Dartmouth Scholarship

Active tuberculosis (TB) is common among HIV-infected persons living in tuberculosis endemic countries, and screening for tuberculosis (TB) is recommended routinely. We sought to determine the role of chest x-ray and sputum culture in the decision to treat for presumptive TB using active case finding in a large cohort of HIV-infected patients. Ambulatory HIV-positive subjects with CD4 counts ≥ 200/mm3 entering a Phase III TB vaccine study in Tanzania were screened for TB with a physical examination, standard interview, CD4 count, chest x-ray (CXR), blood culture for TB, and three sputum samples for acid fast bacillus (AFB) smear and culture.
