D-Dimer Levels Before Hiv Seroconversion Remain Elevated Even After Viral Suppression And Are Associated With An Increased Risk Of Non-Aids Events, Matthew S Freiberg, Ionut Bebu, Russell Tracy, Kaku So-Armah, Jason Okulicz, Anuradha Ganesan, Adam Armstrong, Thomas O'Bryan, David Rimland, Amy C Justice, Brian K Agan

GW Biostatistics Center

The mechanism underlying the excess risk of non-AIDS diseases among HIV infected people is unclear. HIV associated inflammation/hypercoagulability likely plays a role. While antiretroviral therapy (ART) may return this process to pre-HIV levels, this has not been directly demonstrated. We analyzed data/specimens on 249 HIV+ participants from the US Military HIV Natural History Study, a prospective, multicenter observational cohort of >5600 active duty military personnel and beneficiaries living with HIV. We used stored blood specimens to measure D-dimer and Interleukin-6 (IL-6) at three time points: pre-HIV seroconversion, ≥6 months post-HIV seroconversion but prior to ART initiation, and ≥6 months post-ART …

Generalized Confidence Intervals And Fiducial Intervals For Some Epidemiological Measures., Ionut Bebu, G. Luta, T. Mathew, B. K. Agan

GW Biostatistics Center

For binary outcome data from epidemiological studies, this article investigates the interval estimation of several measures of interest in the absence or presence of categorical covariates. When covariates are present, the logistic regression model as well as the log-binomial model are investigated. The measures considered include the common odds ratio (OR) from several studies, the number needed to treat (NNT), and the prevalence ratio. For each parameter, confidence intervals are constructed using the concepts of generalized pivotal quantities and fiducial quantities. Numerical results show that the confidence intervals so obtained exhibit satisfactory performance in terms of maintaining the coverage probabilities …

Interruptions Of Antiretroviral Therapy In Children And Adolescents With Hiv Infection In Clinical Practice: A Retrospective Cohort Study In The Usa., Natella Rakhmanina, Kam S Lam, Jaclyn Hern, Heather A. Young, Alex Walters, Amanda D. Castel

Epidemiology Faculty Publications

INTRODUCTION: Changes in combination antiretroviral therapy (cART) throughout childhood challenge the continuity of paediatric HIV treatment. This study aimed to evaluate the prevalence of treatment interruption (TI), including lamivudine (3TC) monotherapy, and the relationship of TI to virologic and immunologic parameters in HIV-infected paediatric patients.

METHODS: Nested within a prospective observational study of a city-wide cohort of HIV-infected persons in the District of Columbia, this sub-study collected retrospective data on antiretroviral therapy, enrolment (endpoint) and historic (lifelong) CD4 counts and HIV RNA viral load (VL) of the paediatric cohort. TI was defined as interruption of cART ≥4 consecutive weeks. Data …

An Analysis Of Water Collection Labor Among Women And Children In 24 Sub-Saharan African Countries., Jay Graham, Mitsuaki Hirai, Seung-Sup Kim

Environmental and Occupational Health Faculty Publications

BACKGROUND: It is estimated that more than two-thirds of the population in sub-Saharan Africa (SSA) must leave their home to collect water, putting them at risk for a variety of negative health outcomes. There is little research, however, quantifying who is most affected by long water collection times.

OBJECTIVES: This study aims to a) describe gender differences in water collection labor among both adults and children (< 15 years of age) in the households (HHs) that report spending more than 30 minutes collecting water, disaggregated by urban and rural residence; and b) estimate the absolute number of adults and children affected by water collection times greater than 30 minutes in 24 SSA countries.

METHODS: We analyzed data from the Demographic Health Survey (DHS) and the Multiple Indicator Cluster Survey (MICS) (2005-2012) to describe water collection labor in 24 SSA countries.

RESULTS: Among households spending more than …

Legal Space For Syringe Exchange Programs In Hot Spots Of Injection Drug Use-Related Crime., Sean T Allen, Monica S. Ruiz, Jeff Jones, Monique M Turner

Prevention and Community Health Faculty Publications

BACKGROUND: Copious evidence indicates that syringe exchange programs (SEPs) are effective structural interventions for HIV prevention among persons who inject drugs (PWID). The efficacy of SEPs in supporting the public health needs of PWID populations is partially dependent on their accessibility and consistent utilization among injectors. Research has shown that SEP access is an important predictor of PWID retention at SEPs, yet policies exist that may limit the geographic areas where SEP operations may legally occur. Since 2000 in the District of Columbia (DC), SEP operations have been subject to the 1000 Foot Rule (§48-1121), a policy that prohibits the …

The Impact Of An Ambulatory Clinical Intervention On Viral Load Suppression And Retention In Care For Newly Diagnosed Hiv Persons, Latasha R. Jones

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Ambulatory clinical healthcare settings that serve patients infected with the human immunodeficiency virus (HIV) are critical in improving access to quality HIV care and treatment, in part due to their ability to streamline patient care along the HIV care continuum. Barriers to HIV care are significant among newly diagnosed HIV patients and in order to engage and retain these individuals in care and treatment, specific interventions must be in place to link these individuals to care. In this study, the difference in differences method was used for data analysis to measure the impact of an ambulatory clinics intervention on their …

Analysis Of Policy Changes Aimed At Breastfeeding Promotion As Part Of The Special Supplemental Nutrition Program For Women, Infants, And Children (Wic): Making It Work For Michigan, Elizabeth L. Macquillan

Michigan Journal of Public Health

In 2011, changes to the specific type, timing, and amount of food benefits to mothers in the WIC program were rolled out nationwide. These were the first substantive changes since 1980 and were designed to increase breastfeeding initiation rates and extend breastfeeding duration among WIC program participants. Effectiveness of the program changes have been mixed and variable by geographic area of the U.S., however. In Michigan, breastfeeding duration has not increased. This analysis examines the implementation of the national policy change at the state level for Michigan and suggests additions to program to specifically target duration breastfeeding by Michigan mothers.

Antibody-Mediated Immunity To Vibrio Cholerae At Epithelial Surfaces, Kara Jeanette Levinson

Legacy Theses & Dissertations (2009 - 2024)

Vibrio cholerae, the causative agent of the severe diarrheal disease cholera, has an estimated worldwide disease burden in the millions and remains a significant public health threat. Immunity to V. cholerae is primarily antibody-mediated and though V. cholerae colonization evokes a mucosal immune response, it is the secretory IgA (SIgA) antibodies produced against bacterial surface antigens, specifically lipopolysaccharide (LPS) that confer protective immunity. SIgA antibodies are thought to function by inhibiting colonization by cross-linking and agglutination of pathogens, thereby limiting access to the epithelium, a process known as immune exclusion. Recent studies in other enteric pathogens have demonstrated that SIgA …

Establishing Methodology For Occupational Injury Surveillance In Agriculture And Logging, Erika Elisabeth Scott

Legacy Theses & Dissertations (2009 - 2024)

Developing a low-cost surveillance system for occupational injury in agriculture and logging has long been a challenge. These data are needed to prioritize public health interventions in the agriculture and logging industries, and are crucial to evaluating changes in injury rates, as well as the effectiveness of safety interventions. Recently, the transition to electronic data reporting created new opportunities for the development of sustainable, low-cost surveillance systems. Pre-hospital care reports (PCR) and hospital data (emergency department, inpatient, and outpatient) are datasets of particular interest.

The Relationship Of Sexual Health Education And Sexual Health Risk Behavioral Outcomes Among Florida Teens, Brandon Moton, Rima Tawk

Florida Public Health Review

We examined the relationship between sexual health education and sexual health risk behavioral outcomes among adolescents in Florida using Youth Risk Behavior Survey data from 2001 to 2013. Sexual health risk behavioral outcomes (reported condom use and alcohol and/or drug use during last intercourse) were first examined as a function of sexual health education. Multiple logistic regression analysis was then used to adjust for individual characteristics and behavioral risk factors when associating sexual health education with sexual health risk behavioral outcomes. Reported condom use was strongly associated with sexual education. However, the impact of sexual education was attenuated after adjusting …

Climate Change And Malaria Control: The Importance Of Mitigation And A Call To Action, Emmanuel O. Adewuyi, Kazeem Adefemi

Research outputs 2014 to 2021

Malaria has remained an important target for global disease control efforts for decades. The streams of funds and, consequently, availability of effective interventions for the disease have resulted in considerable reduction in its burden, globally. Despite the relative success of such global efforts, malaria remains a significant threat in over a hundred countries, worldwide, leading to about one million deaths and hundreds of millions of hospital visits, annually. Many researchers and health commentators have argued that global warming, a consequence of climate change, could be linked – directly or indirectly – to the persistence as well as the re-emergence of …

Epidemiology Of Plasmodium And Helminth Coinfection And Possible Reasons For Heterogeneity, Abraham Degarege, Berhanu Erko

Journal Articles: Epidemiology

Understanding the impact of helminth infections on clinical malaria is useful for designing effective malaria control strategies. Plenty of epidemiological studies have been conducted to unravel the nature of interactions between Plasmodium and helminth infection. Careful broad summarization of the existing literature suggests that Schistosoma mansoni and hookworm infections may increase the risk of clinical malaria and associated morbidities, but Trichuris trichiura infection is not associated with the occurrence of clinical malaria and related outcomes. However, findings about effect of Ascaris lumbricoides and Schistosoma haematobium infection on clinical malaria are contradictory. Furthermore, the nature of relationship of helminth infection with …

Are You Pepped And Prepped For Travel? Risk Mitigation Of Hiv Infection For Travelers, David Brett-Major, P. T. Scott, T A. Crowell, C. S. Polyak, K. Modjarrad, M. L. Robb, D. L. Blazes

Journal Articles: Epidemiology

The HIV pandemic persists globally and travelers are at risk for infection by the Human Immunodeficiency Virus (HIV). While HIV-focused guidelines delineate risk stratification and mitigation strategies for people in their home communities, travel issues are not addressed. In this review, direct and indirect evidence on HIV risk among travelers is explored. The burgeoning practice of employing pre-exposure prophylaxis (PrEP) with anti-retroviral therapy in the non-travel setting is introduced, as well as the more established use of post-exposure prophylaxis (PEP). Challenges in applying these lessons to travelers are discussed, and a new guidelines process is scoped and recommended.

The Evolution Of The Intersection Of Hiv And Breastfeeding In Global Policy, Kristin M. Sinning

Master of Public Health Program Student Publications

Increasing breastfeeding rates and reducing HIV/AIDS are two important global health priorities, and their intersection has led to policies that meet mutual goals of supporting, protecting and promoting breastfeeding and reducing the risk of HIV/AIDS. The World Health Organization has developed and released recommendations, policies, and guidance on infant feeding and the risk of transmission through breastfeeding. This analysis provides a historical, chronological perspective on the global policies for infant feeding in the case of an HIV-positive mother, an analysis of changes, and recommendations for the future. The policies evaluated demonstrate the evolution in knowledge and recommendations for infant feeding …

Strengths And Challenges Of A Rural Ohio Public Health Department: Considerations For Effective Service Delivery And Emergency Preparedness, Cindy L. Harris Graessle

Master of Public Health Program Student Publications

The local public health department is the main entity in cities and counties established to ensure the safety, health, and well-being of its community members. In many cases, particularly in rural areas, the health department may be the community’s closest access to health care, providing not only clinical care, but preventive services as well. These rural health departments have additional challenges that may not be experienced in the larger, more populated metropolitan areas. These challenges include lack of resources and funding that impact daily operations, expanded registered sanitarian responsibilities, and emergency preparedness difficulties with resource allocation and communication. Despite these …

Comparison Of The Difference In Nephrotoxicity Between Nafcillin And Piperacillin-Tazobactam, Sonali Kishor Patel

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Objective

To evaluate whether nephrotoxicity differs between nafcillin and piperacillin-tazobactam in adult hospitalized patients.

Introduction

Acute kidney injury (AKI) is a significant cause of morbidity and mortality in the inpatient setting, with antibiotics being a significant contributor. There is evidence of an increased risk of nephrotoxicity with the combination of vancomycin and piperacillin-tazobactam compared to vancomycin and cefepime or vancomycin alone. It is unknown whether this effect is exclusive for piperacillin-tazobactam. Therefore, in order to promote optimal medication therapy for inpatient bacterial infections, there is a need to assess the persistence of this difference in other beta-lactam antibiotics.

Methods
