Fighting Microbial Drug Resistance: A Primer On The Role Of Evolutionary Biology In Public Health, Gabriel Perron, R. Inglis, Pleuni Pennings, Sarah Cobey

Biology Department Faculty Works

Although microbes have been evolving resistance to antimicrobials for millennia, the spread of resistance in pathogen populations calls for the development of new drugs and treatment strategies. We propose that successful, long-term resistance management requires a better understanding of how resistance evolves in the first place. This is an opportunity for evolutionary biologists to engage in public health, a collaboration that has substantial precedent. Resistance evolution has been an important tool for developing and testing evolutionary theory, especially theory related to the genetic basis of new traits and constraints on adaptation. The present era is no exception. The articles in …

Evaluation Of The Benefits And Risks Of Introducing Ebola Community Care Centers, Sierra Leone, Adam J. Kucharski, Anton Camacho, Francesco Checchi, Ronald J. Waldman, Rebecca F. Grais, Jean-Clement Cabrol, Sylvie Briand, Marc Baguelin, Stefan Flasche, Sebastian Funk, W. John Edmunds

Global Health Faculty Publications

In some parts of western Africa, Ebola treatment centers (ETCs) have reached capacity. Unless capacity is rapidly scaled up, the chance to avoid a generalized Ebola epidemic will soon diminish. The World Health Organization and partners are considering additional Ebola patient care options, including community care centers (CCCs), small, lightly staffed units that could be used to isolate patients outside the home and get them into care sooner than otherwise possible. Using a transmission model, we evaluated the benefits and risks of introducing CCCs into Sierra Leone’s Western Area, where most ETCs are at capacity. We found that use of …

Law, Ethics, And Public Health In The Vaccination Debates: Politics Of The Measles Outbreak, Lawrence O. Gostin

Georgetown Law Faculty Publications and Other Works

The measles outbreak of early 2015 is symptomatic of a larger societal problem–the growing number of parents who decide against vaccinating their children. This failure is causing the resurgence of childhood diseases once eliminated from the United States.

This article explores the legal and ethical landscape of vaccine exemptions. While all states require childhood vaccinations, they differ significantly in the types of religious and/or philosophical exemptions permitted, the rigor of the application process, and available review mechanisms. States with relaxed exemption policies disproportionately experience more outbreaks of vaccine-preventable disease.

Vaccine exemptions are an illustration of the “tragedy of the commons,” …

Impact Of Hiv Testing And Counseling (Htc) Knowledge On Hiv Prevention Practices Among Traditional Birth Attendants In Nigeria, Alice Osuji, Jennifer R. Pharr, Uche Nwokoro, Anulika Ike, Christiana Ali, Ogheneaga Ejiro, John Osuyali, Michael Obiefune, Kevin Fiscella, Echezona E. Ezeanolue

Environmental & Global Health Faculty Research

Nigeria is second in the world for the number of people with HIV and has a high rate of mother-to-child transmission (MTCT). Over 60% of births in Nigeria occur outside of health care facilities, and because of this, Traditional Birth Attendants (TBAs) play a significant role in maternal and child health. It is important that TBAs be knowledgeable about HIV prevention. The purpose of this study was to determine the impact of HIV testing and counseling (HTC) knowledge on the HIV prevention practices among TBAs in Nigeria. Five hundred TBAs were surveyed. Chi-square and logistic regression were used to assess …

Price Subsidies, Diagnostic Tests, And Targeting Of Malaria Treatment: Evidence From A Randomized Controlled Trial, Jessica Cohen, Pascaline Dupas, Simone Schaner

Dartmouth Scholarship

Both under- and over-treatment of communicable diseases are public bads. But efforts to decrease one run the risk of increasing the other. Using rich experimental data on household treatment- seeking behavior in Kenya, we study the implications of this trade-off for subsidizing life-saving antimalarials sold over-the-counter at retail drug outlets. We show that a very high subsidy (such as the one under consideration by the international community) dramatically increases access, but nearly one-half of subsidized pills go to patients without malaria. We study two ways to better target subsidized drugs: reducing the subsidy level, and introducing rapid malaria tests over-the-counter. …

• Truckers spend 3+ days waiting to be processed, providing a costumer base for prostitution
• In Kenya, 27.6% of female sex workers are HIV positive and only 26.8% use condoms with all of their partners (Morris, Morris, and Ferguson, 2009).
• The rampant spread of HIV and lack of contraception has led to rapid growth in the population in an area that has little ability to support any residents
• Development of Slums that now line the highway

Target Zero: Why States Choose To Eradicate Infectious Diseases And How They Succeed, Gifty Abraham

Dissertations, Theses, and Capstone Projects

Realism has remained the dominant paradigm within international relations for most of the modern era, emphasizing the competitive nature of the international arena and the unlikeliness of states to within it to cooperate. The attempts and further still, successes, by states to eradicate infectious diseases--which remain among the most cooperative enterprises--present a number of challenges to realism's assumptions, particularly with respect to the unlikely world historical-times during which the eradication campaigns took place. As such, a two-part puzzle arises. First, why would states, which are natural competitors, cooperate to eradicate infectious diseases given structural and situational incentives not to do …

Risk Factors And Costs Influencing Hospitalizations Due To Heat-Related Illnesses: Patterns Of Hospitalization, Michael T. Schmeltz

Dissertations, Theses, and Capstone Projects

The objective of this dissertation was to identify individual and environmental risk factors, investigate outcomes and hospital resource use, including costs, and document the pattern of heat-related illness hospitalizations in the United States. The main data source for the study population was the 2001-2010 Nationwide Inpatient Sample (NIS). The study population for heat-related illnesses (HRIs) consists of patients in the NIS with at least one diagnosis of a heat-related illness (ICD-9 codes 992.0 - 992.9) from 2001 to 2010. Outcome analysis included a study population of patients who had primary or secondary diagnoses of diabetes, cardiovascular diseases, respiratory illnesses, nephritic …

Validating Estimates Of Prevalence Of Non-Communicable Diseases Based On Household Surveys: The Symptomatic Diagnosis Study, Spencer L. James, Minerva Romero, Dolores Ramírez-Villalobos, Sara Gómez

Dartmouth Scholarship

Easy-to-collect epidemiological information is critical for the more accurate estimation of the prevalence and burden of different non-communicable diseases around the world. Current measurement is restricted by limitations in existing measurement systems in the developing world and the lack of biometry tests for non-communicable diseases. Diagnosis based on self-reported signs and symptoms (“Symptomatic Diagnosis,” or SD) analyzed with computer-based algorithms may be a promising method for collecting timely and reliable information on non-communicable disease prevalence. The objective of this study was to develop and assess the performance of a symptom-based questionnaire to estimate prevalence of non-communicable diseases in low-resource areas.

A Comparison Of Sexual Health And Sexual Pressure Among Young African American And Caucasian Women, Ann Gakumo

Journal of Health Disparities Research and Practice

Introduction. Condom self-efficacy, positive attitudes toward condom use, condom negotiation skills, HIV knowledge, and self-esteem have been associated with decreased HIV risk behavior among young women, but few studies have examined racial disparities that may exist in these social health indicators. Moreover, sexual pressure (inclusive of both coercive and non-coercive pressures to engage in unwanted or unprotected sex) has been understudied in women of different racial groups.

Study Purpose. The purpose of this study was to compare racial similarities and disparities in indicators of sexual health and sexual pressure in an urban sample of young African American and Caucasian women …

Journal of Health Disparities Research and Practice

HIV-positive individuals are living longer today as a result of continuing advances in treatment but are also facing an increased risk for chronic diseases such as diabetes, and hypertension. These conditions result in a larger burden of hospitalization, outpatient, and emergency room visits. Impoverished African American women may represent an especially high-risk group due to disparities in health care, racial discrimination, and limited resources. This article describes an intervention that is based on the conceptual framework of the socio-ecological model. Project THANKS uses a community-based participatory, and empowerment building approach to target the unique personal, social, and environmental needs of …

Sexual Decision Making In The Absence Of Choice: The African American Female Dating Experience., Michele Peake Andrasik, Hong V. Nguyen, William H. George, Kelly F. Kajumulo

Journal of Health Disparities Research and Practice

Although links between low mate availability and increased HIV and STI risk for African American women have been documented in the literature, we know little about the impact of limited mate choices on the quality of relationships between Black men and women and how these relationship dynamics impact risk for young Black women. We conducted a qualitative study with African American female young adults (N=12) to explore the perceived impact of structural forces on African American female young adults’ dating and sexual behavior. Participants reported (1) perceptions of Black men as untrustworthy and manipulative, (2) the limited and often negative …

Do Masculinity And Perceived Condom Barriers Predict Heterosexual Hiv Risk Behaviors Among Black Substance Abusing Men?, A, Kathleen Burlew, Jerika Wilson, Latrice Montgomery, Bridgette Peteet, Candace Johnson, Mary Hatch-Maillette

Journal of Health Disparities Research and Practice

Although HIV prevention during substance abuse treatment is ideal, existing HIV risk-reduction interventions are less effective among Black and other ethnic minority substance abusers. The Sexual Health Model (SHM) and the Person, Extended Family and Neighborhood-3 model (PEN-3) both highlight the importance of increasing our understanding of the relationship of sociocultural factors to sexual-decision making as a step towards developing more HIV prevention interventions for ethnic minorities. However, few studies examine sociocultural factors in the sexual decision-making process of Black substance abusing men. This secondary analysis of data collected in an evaluation of Real Men Are Safe (REMAS), a HIV …

A Case Of Cutaneous Larva Migrans Presenting In A Pregnant Patient., Kasie Kudrewicz, Kylee N Crittenden, Alison Himes

Women’s Health Articles

Cutaneous larva migrans (CLM) is a pruritic dermatitis caused by migration of animal hookworm larvae into the skin. We present a case of CLM in a 31-year-old pregnant woman. The treatment of CLM relies on antihelminthic agents, such as thiabendazole, albendazole, and ivermectin. This case was interesting in that the standard treatment options previously mentioned were contraindicated owing to the patient's pregnancy. Cryotherapy with liquid nitrogen resulted in complete resolution of her lesion and symptoms.

Mapping Of Networks To Detect Priority Zoonoses In Jordan, Erin M. Sorrell, Mohammad El Azhari, Nezar Maswdeh, Sarah Kornblet, Claire J. Standley, Rebecca L. Katz, Ibrahim Ablan, Julie E. Fischer

Health Policy and Management Faculty Publications

Early detection of emerging disease events is a priority focus area for cooperative bioengagement programs. Communication and coordination among national disease surveillance and response networks are essential for timely detection and control of a public health event. Although systematic information sharing between the human and animal health sectors can help stakeholders detect and respond to zoonotic diseases rapidly, resource constraints and other barriers often prevent efficient cross-sector reporting. The purpose of this research project was to map the laboratory and surveillance networks currently in place for detecting and reporting priority zoonotic diseases in Jordan in order to identify the nodes …

C. Ashish, Sayed Rubayet, Subrata Bhadra, Reuben Ligowe, Emmanuel Chimbalanga, Elizabeth Sewell, Kate Kerber, Allisyn Moran

Pediatrics Faculty Publications

Background: Nearly all newborn deaths occur in low- or middle-income countries. Many of these deaths could be prevented through promotion and provision of newborn care practices such as thermal care, early and exclusive breastfeeding, and hygienic cord care. Home visit programmes promoting these practices were piloted in Malawi, Nepal, Bangladesh, and Uganda.

Objective: This study assessed changes in selected newborn care practices over time in pilot programme areas in four countries and evaluated whether women who received home visits during pregnancy were more likely to report use of three key practices.

Design: Using data from cross-sectional surveys …

The Evidence Does Not Speak For Itself: The Role Of Research Evidence In Shaping Policy Change For The Implementation Of Publicly Funded Syringe Exchange Programs In Three Us Cities, Sean T. Allen, Monica S. Ruiz, Allison O'Rourke

Prevention and Community Health Faculty Publications

BACKGROUND:

A breadth of literature exists that explores the utilization of research evidence in policy change processes. From this work, a number of studies suggest research evidence is applied to change processes by policy change stakeholders primarily through instrumental, conceptual, and/or symbolic applications, or is not used at all. Despite the expansiveness of research on policy change processes, a deficit exists in understanding the role of research evidence during change processes related to the implementation of structural interventions for HIV prevention among injection drug users (IDU). This study examined the role of research evidence in policy change processes for the …

Effectiveness Of Fecal-Derived Microbiota Transfer Using Orally Administered Capsules For Recurrent Clostridium Difficile Infection, B. E. Hirsch, N. Saraiya, K. Poeth, R. M. Schwartz, M. E. Epstein, G. Honig

Journal Articles

BACKGROUND: Clostridium difficile infection (CDI), a complication of antibiotic-induced injury to the gut microbiome, is a prevalent and dangerous cause of infectious diarrhea. Antimicrobial therapy for CDI is typically effective for acute symptoms, but up to one third of patients later experience recurrent CDI. Fecal-derived microbiota transplantation (FMT) can ameliorate the underlying dysbiosis and is highly effective for recurrent CDI. Traditional methods of FMT are limited by patient discomfort, risk and inefficient procedures. Many individuals with recurrent CDI have extensive comorbidities and advanced age. Widespread use of FMT requires strategies that are non-invasive, scalable and applicable across healthcare settings. METHODS: …

Seasonal Variations Of Complete Blood Count And Inflammatory Biomarkers In The Us Population - Analysis Of Nhanes Data, B. Liu, E. Taioli

Journal Articles

BACKGROUND: Recent studies reported seasonal differences in gene expression in white blood cells, adipose tissue, and inflammatory biomarkers of the immune system. There is no data on the seasonal variations of these biomarkers in the US general population of both children and adults. Then aim of this study is to explore the seasonal trends in complete blood count (CBC), and C-reactive protein (CRP) in a large non-institutionalized US population. METHODS: Seven cross-sectional data collected in the National Health and Nutrition Examination Survey (NHANES) during 1999-2012 were aggregated; participants reporting recent use of prescribed steroids, chemotherapy, immunomodulators and antibiotics were excluded. …

Detecting Signals Of Seasonal Influenza Severity Through Age Dynamics, Elizabeth C Lee, Cécile Viboud, Lone Simonsen, Farid Khan, Shweta Bansal

Global Health Faculty Publications

BACKGROUND: Measures of population-level influenza severity are important for public health planning, but estimates are often based on case-fatality and case-hospitalization risks, which require multiple data sources, are prone to surveillance biases, and are typically unavailable in the early stages of an outbreak. To address the limitations of traditional indicators, we propose a novel severity index based on influenza age dynamics estimated from routine physician diagnosis data that can be used retrospectively and for early warning.

METHODS: We developed a quantitative 'ground truth' severity benchmark that synthesizes multiple traditional severity indicators from publicly available influenza surveillance data in the United …

The Inclusion Of Women’S Health In Sustainable Medical Mission Trip Models: A Pa Student’S Perspective, Jillian G. Goles

VA Engage Journal

Like many disadvantaged countries around the world, Nicaragua is visited by numerous medical missions each year. The efficacy of these missions relies on the organization’s relationship with the communities they serve. Although the general goal of all medical missions is to ultimately help underserved populations, many missions inadvertently do harm. Two critical causes of such inadvertent harm are lack of sustainable practices and failure to form a long-term relationship with the communities. Shenandoah University’s Physician Assistant Program has worked tirelessly to form an ideal medical mission model and relationship with El Ayudante, a local non-government humanitarian organization, and the local …

Association Between Respiratory Syncytial Virus Activity And Pneumococcal Disease In Infants: A Time Series Analysis Of Us Hospitalization Data., Daniel M. Weinberger, Keith P. Klugman, Claudia A. Steiner, Lone Simonsen, Cécile Viboud

Epidemiology Faculty Publications

BACKGROUND:

The importance of bacterial infections following respiratory syncytial virus (RSV) remains unclear. We evaluated whether variations in RSV epidemic timing and magnitude are associated with variations in pneumococcal disease epidemics and whether changes in pneumococcal disease following the introduction of seven-valent pneumococcal conjugate vaccine (PCV7) were associated with changes in the rate of hospitalizations coded as RSV.

METHODS AND FINDINGS:

We used data from the State Inpatient Databases (Agency for Healthcare Research and Quality), including >700,000 RSV hospitalizations and >16,000 pneumococcal pneumonia hospitalizations in 36 states (1992/1993-2008/2009). Harmonic regression was used to estimate the timing of the average seasonal …
