Facing An Epidemic: An Analysis Of Hiv/Aids, Antiretroviral Drug, And International Response To The Aids Pandemic, Michael Tate

Annual Undergraduate Conference on Health and Society

More than 33 million people are living with HIV/AIDS around the globe with 68% of all cases occurring in sub-Saharan Africa. The global prevalence rate is shocking considering that the disease was relatively unknown just 30 years ago. After reviewing medical, health policy, and health statistical journals, I will argue in this paper that international aid to nations struggling with AIDS needs to be redirected and refocused on supplying antiretroviral therapy to afflicted nations because ARV has been proven to be effective in managing the disease in countries that can afford the costs of treatment. International aid to countries that …

Individual And Social Determinants Of Multiple Chronic Disease Behavioral Risk Factors Among Youth, Arsham Alamian, Gilles Paradis

ETSU Faculty Works

BACKGROUND: Behavioral risk factors are known to co-occur among youth, and to increase risks of chronic diseases morbidity and mortality later in life. However, little is known about determinants of multiple chronic disease behavioral risk factors, particularly among youth. Previous studies have been cross-sectional and carried out without a sound theoretical framework.

METHODS: Using longitudinal data (n = 1135) from Cycle 4 (2000-2001), Cycle 5 (2002-2003) and Cycle 6 (2004-2005) of the National Longitudinal Survey of Children and Youth, a nationally representative sample of Canadian children who are followed biennially, the present study examines the influence of a set of …

Epidemiology Faculty Publications

Background

Preterm birth is the principal factor contributing to adverse outcomes in multiple pregnancies. Randomized controlled trials of progestogens to prevent preterm birth in twin pregnancies have shown no clear benefits. However, individual studies have not had sufficient power to evaluate potential benefits in women at particular high risk of early delivery (for example, women with a previous preterm birth or short cervix) or to determine adverse effects for rare outcomes such as intrauterine death.

Methods/design

We propose an individual participant data meta-analysis of high quality randomized, double-blind, placebo-controlled trials of progestogen treatment in women with a twin pregnancy. The …

Does Secondary Inflammatory Breast Cancer Represent Post-Surgical Metastatic Disease?, Salman Hashmi, Ladan Zolfaghari, Paul H. Levine

Epidemiology Faculty Publications

The phenomenon of accelerated tumor growth following surgery has been observed repeatedly and merits further study. Inflammatory breast carcinoma (IBC) is widely recognized as an extremely aggressive malignancy characterized by micrometastasis at the time of diagnosis, with one interesting subgroup defined as secondary IBC where pathologically identifiable IBC appears after surgical treatment of a primary non-inflammatory breast cancer. One possible mechanism can be related to the stimulation of dormant micrometastasis through local angiogenesis occurring as part of posttraumatic healing. In this report, we review cases of secondary IBC and others where localized trauma was followed by the appearance of IBC …

Alternate Estrogen Receptors Promote Invasion Of Inflammatory Breast Cancer Cells Via Non-Genomic Signaling, Kazufumi Ohshiro, Arnold M. Schwartz, Paul H. Levine, Rakesh Kumar

Epidemiology Faculty Publications

Although Inflammatory Breast Cancer (IBC) is a rare and an aggressive type of locally advanced breast cancer with a generally worst prognosis, little work has been done in identifying the status of non-genomic signaling in the invasiveness of IBC. The present study was performed to explore the status of non-genomic signaling as affected by various estrogenic and anti-estrogenic agents in IBC cell lines SUM149 and SUM190. We have identified the presence of estrogen receptor α (ERα) variant, ERα36 in SUM149 and SUM190 cells. This variant as well as ERβ was present in a substantial concentration in IBC cells. The treatment …

A Spatial Cluster Analysis Of Tractor Overturns In Kentucky From 1960 To 2002, Daniel M. Saman, Henry P. Cole, Agricola Odoi, Melvin L. Myers, Daniel I. Carey, Susan C. Westneat

Epidemiology and Environmental Health Faculty Publications

BACKGROUND: Agricultural tractor overturns without rollover protective structures are the leading cause of farm fatalities in the United States. To our knowledge, no studies have incorporated the spatial scan statistic in identifying high-risk areas for tractor overturns. The aim of this study was to determine whether tractor overturns cluster in certain parts of Kentucky and identify factors associated with tractor overturns.

METHODS: A spatial statistical analysis using Kulldorff's spatial scan statistic was performed to identify county clusters at greatest risk for tractor overturns. A regression analysis was then performed to identify factors associated with tractor overturns.

RESULTS: The spatial analysis …

Atrazine Exposure In Public Drinking Water And Preterm Birth, Jessica L. Rinsky, Claudia Hopenhayn, Vijay Golla, Steven R. Browning, Heather M. Bush

Epidemiology and Environmental Health Faculty Publications

Objectives

Approximately 13% of all births occur prior to 37 weeks gestation in the U.S. Some established risk factors exist for preterm birth, but the etiology remains largely unknown. Recent studies have suggested an association with environmental exposures. We examined the relationship between preterm birth and exposure to a commonly used herbicide, atrazine, in drinking water.

Methods

We reviewed Kentucky birth certificate data for 2004–2006 to collect duration of pregnancy and other individual-level covariates. We assessed existing data sources for atrazine levels in public drinking water for the years 2000–2008, classifying maternal county of residence into three atrazine exposure groups. …

Hiv/Aids In The Muslim-Majority Countries: Formula For Low Prevalence, Kaoru Yamaguchi

Political Science Theses and Capstones

The Muslim-majority countries long had been considered to be free of HIV/AIDS epidemic because of their strict religious and moral codes. However, the HIV prevalence rates are increasing in some Islamic states, and even more or so rapidly in a several cases that it is no longer valid to assume the Islamic religion protects its followers from the risks of contracting HIV. Contrary to the popular belief concerning the prevention of the HIV/AIDs epidemic, data collected from well-recognized international organizations such as the WHO and Freedom House indicate that democratization, strong government leadership, and wider and equal human rights for …

The Effects Of The Built Environment On Physical Activity In Rural Upstate New York, Kimberly Moore

Legacy Theses & Dissertations (2009 - 2024)

Background: Physical activity across the lifespan is associated with numerous health benefits. That the built environment can influence physical activity is a widely accepted hypothesis which has been examined extensively in urban/suburban and across urban-rural environments. Numerous census variables, such as housing density, percent renter, and others related to urbanity, are related to physical activity and built environment measures. However, the rural built environment's influence on adult physical activity is relatively unexplored.

The Burden Of Hepatitis C Virus In New York State, Rachel Hart Malloy

Legacy Theses & Dissertations (2009 - 2024)

Hepatitis C virus (HCV) infection is estimated to be the most common chronic blood-borne infection in the United States (US). Annual incidence of HCV in the US peaked in the late 1980's, declined steadily through the 1990's and has plateaued since 2003 with approximately 18,000 new cases in 2008. The morbidity and mortality associated with HCV is expected to rise until at least 2015. Due to the high rate of asymptomatic cases, inherent limitations with target screening recommendations, limitations with screening technologies and scarce resources for surveillance nationwide, quantification of the burden is difficult. US estimates of disease burden have …

The Association Of Summer Temperatures With Hospital Admissions For Renal Diseases In New York State : A Case-Crossover Study, Barbara A. Fletcher

Legacy Theses & Dissertations (2009 - 2024)

This study assessed the association between high temperatures and increased odds of hospitalization for renal diseases which, to date, has been examined in only a small number of studies. A case-crossover design was used to study 147,885 hospital admissions with renal diagnoses during July and August, 1991-2004 in New York State. Regional temperature, humidity and barometric pressure data from automated monitors were used as exposure indicators. Using time-stratified referent selection and conditional logistic regression analysis, an overall 9% increase in odds of hospitalization for acute renal failure per 5°F (2.78°C) was found for mean temperature at a one day lag …

Detection And Epidemiological Patterns Of Drug Resistance Mutations In Nys Plasmodium Falciparum Clinical Malaria Specimens, Jennifer L. Conaway

Legacy Theses & Dissertations (2009 - 2024)

Plasmodium falciparum is a human-infective parasite that causes the most severe form of malaria. Resistance to a wide spectrum of antimalarials has been documented in this species, and single strains may be resistant to several drugs. A new technology, pyrosequencing, has been shown to be useful for the rapid detection of SNPs involved in drug resistance. It can be used in a clinical setting and readily detects new mutants, which frequently appear in this species due to strong selection for antimalarial resistance. In this study, a pyrosequencing protocol was developed to identify mutations in the Plasmodium falciparum genes Pfcrt, Pfdhps, …

Occupational Exposure And Risk Of Skin Cancer In A Multinational European Study, Simona Surdu

Legacy Theses & Dissertations (2009 - 2024)

Non-melanoma skin cancers (NMSC) comprise more than one third of all cancers, and are increasing worldwide. The most common NMSC are Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC). Studies on humans and animals suggest that sunlight and arsenic play important roles in the pathogenesis of these skin malignancies. However, the number of epidemiological studies focusing on NMSC in workers exposed to ultraviolet (UV) radiation or airborne arsenic is limited, and the findings are contradictory.
