Perceptions Of Peer Sexual Behavior: Do Adolescents Believe In A Sexual Double Standard?, Michael Young, Susan Cardenas, Joseph Donnelly, Mark J. Kittleson

Department of Public Health Scholarship and Creative Works

BACKGROUND

The purpose of the study was to (1) examine attitudes of adolescents toward peer models having sex or choosing abstinence, and (2) determine whether a “double standard” in perception existed concerning adolescent abstinence and sexual behavior.

METHODS

Adolescents (N = 173) completed questionnaires that included 1 of 6 randomly assigned vignettes that described male and female peer models 3 ways: (1) no information about model's sexual behavior, (2) model in love but choosing abstinence, and (3) model in love and having sex. Participants read the vignette to which they had been assigned and responded to statements about the peer …

Creating Sustainable Models For Short-Term Volunteers Through The Global Health Service Partnership, James Scott, +Several Additional Authors

Emergency Medicine Faculty Posters and Presentations

Thirty-one countries in sub-Saharan Africa (SSA) have a critical shortage of health care professionals. Subsequently, African medical schools are increasing enrollment, thus increasing demand on limited faculty. Simultaneously, US medical residents’ interest in global health is increasing and training programs are seeking ways to provide high quality experiences while also contributing to the host country health system. Recently published guidelines outlined key factors in successful global health training partnerships: structured programs, mutual benefits, long-term relationships, on-site mentorship, and trainee preparation. Partnerships between US academic institutions, GHSP, and SSA institutions create meaningful and sustainable ways of enabling residents and faculty across …

Progress Toward Eliminating Mother To Child Transmission Of Hiv In Kenya: Review Of Treatment Guideline Uptake And Pediatric Transmission At Four Government Hospitals Between 2010 And 2012., Sarah Finocchario-Kessler, Kristine F. Clark, Samoel Khamadi, Brad J. Gautney, Vincent Okoth, Kathy Goggin, Hitsystem Study Team

Manuscripts, Articles, Book Chapters and Other Papers

We analyzed prevention of mother-to-child transmission (PMTCT) data from a retrospective cohort of n = 1365 HIV+ mothers who enrolled their HIV-exposed infants in early infant diagnosis services in four Kenyan government hospitals from 2010 to 2012. Less than 15 and 20 % of mother-infant pairs were provided with regimens that met WHO Option A and B/B+ guidelines, respectively. Annually, the gestational age at treatment initiation decreased, while uptake of Option B/B+ increased (all p's < 0.001). Pediatric HIV infection was halved (8.6-4.3 %), yet varied significantly by hospital. In multivariable analyses, HIV-exposed infants who received no PMTCT (AOR 4.6 [2.49, 8.62], p < 0.001), mixed foods (AOR 5.0 [2.77, 9.02], p < 0.001), and care at one of the four hospitals (AOR 3.0 [1.51, 5.92], p = 0.002) were more likely to be HIV-infected. While the administration and uptake of WHO PMTCT guidelines is improving, an expanded focus on retention and medication adherence will further reduce pediatric HIV transmission.

Testing Modeling Assumptions In The West Africa Ebola Outbreak, Matthew C. Ingram, Keith Burghardt, Christopher Verzijl, Junming Huang, Binyang Song, Marie-Pierre Hasne

Political Science Faculty Scholarship

The Ebola virus in West Africa has infected almost 30,000 and killed over 11,000 people. Recent models of Ebola Virus Disease (EVD) have often made assumptions about how the disease spreads, such as uniform transmissibility and homogeneous mixing within a population. In this paper, we test whether these assumptions are necessarily correct, and offer simple solutions that may improve disease model accuracy. First, we use data and models of West African migration to show that EVD does not homogeneously mix, but spreads in a predictable manner. Next, we estimate the initial growth rate of EVD within country administrative divisions and …

NYMC Faculty Publications

Background Non-fatal outcomes of disease and injury increasingly detract from the ability of the world's population to live in full health, a trend largely attributable to an epidemiological transition in many countries from causes affecting children, to non-communicable diseases (NCDs) more common in adults. For the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015), we estimated the incidence, prevalence, and years lived with disability for diseases and injuries at the global, regional, and national scale over the period of 1990 to 2015. Methods We estimated incidence and prevalence by age, sex, cause, year, and geography with …

Breast Is Best: Determinants Of Breastfeeding In Bali, Leah Hardenbergh

Independent Study Project (ISP) Collection

Breastfeeding greatly benefits the health of newborns, providing them with needed antibodies and protection from numerous diseases, including some of the leading causes of infant mortality. This paper explores breastfeeding practices in Bali, and the wide array of factors that have led to these practices. After discussing how breastfeeding fits into the larger context of maternal and newborn health, I explain factors in Bali that affect a woman’s decision to breastfeed and experience while breastfeeding. Determinants include those related to health, financial position, and social status. I explore the history of formula companies and formula as an alternative to breastmilk, …

Characterizing The Reproduction Number Of Epidemics With Early Subexponential Growth Dynamics., Gerardo Chowell, Cécile Viboud, Lone Simonsen, Seyed M Moghadas

Global Health Faculty Publications

Early estimates of the transmission potential of emerging and re-emerging infections are increasingly used to inform public health authorities on the level of risk posed by outbreaks. Existing methods to estimate the reproduction number generally assume exponential growth in case incidence in the first few disease generations, before susceptible depletion sets in. In reality, outbreaks can display subexponential (i.e. polynomial) growth in the first few disease generations, owing to clustering in contact patterns, spatial effects, inhomogeneous mixing, reactive behaviour changes or other mechanisms. Here, we introduce the generalized growth model to characterize the early growth profile of outbreaks and estimate …

The Road Into The Future Of Health Care: The Importance Of Addressing Access To Health Facilities In Transportation Infrastructure Investment Decisions, Nicola (Nikki) Van Den Heever

Independent Study Project (ISP) Collection

Background: One school of thought argues that transportation infrastructure is not an ultimate end goal of development and therefore shouldn’t be addressed within development funding decisions while the other argues that transportation infrastructure is the crucial foundation from which all development efforts are based and therefore needs to be addressed within development funding decisions. Within this framework, there is a lack of academic and other research addressing how physical access to health care for pregnant women can better be addressed when making decisions regarding funding of transportation infrastructure projects.

Purpose: To demonstrate the importance of considering access to health care …

Zika Virus And Global Health Security, Lawrence O. Gostin, James G. Hodge Jr.

Georgetown Law Faculty Publications and Other Works

Americans are largely apathetic about the risks of Zika virus and Congress cannot agree on preparedness funding. Strategies to counter the spread of Zika by the World Health Organisation (WHO) grossly underestimate the disease’s impact. WHO and member countries lack sufficient resources to respond. Consequences of fiscal apathy can be measured in lives lost and long-term disabilities. Zika prevention is a matter of global health security.

The epidemiologic brunt of Zika in South America falls largely on vulnerable women at heightened risk of exposure through mosquitoes and sexual transmission. Resulting transmission to fetuses and infants will have generational impacts in …

The questions delineated different aspects of people’s disabilities and impairment, and asked a multitude of questions regarding social, economic, political, and other contexts, influenced by the conceptual framework of the International Classification of Functioning (ICF). The study analyzed all of the factors as specified by the questionnaire and found that many varying trends over all types of prosthetic users. The study also used the …

‘Because I Don’T Know’: Uncertainty And Ambiguity In Closed-Ended Reports Of Perceived Discrimination In Us Health Care, Chih-Yuan Lee, Amy Irby-Shasanmi

Department of Public Health Scholarship and Creative Works

Objective

Surveys often ask respondents to assess discrimination in health care. Yet, patients’ responses to one type of widely used measure of discrimination (single-item, personally mediated) tend to reveal prevalence rates lower than observational studies would suggest. This study examines the meaning behind respondents’ closed-ended self-reports on this specific type of measure, paying special attention to the frameworks and references used within the medical setting.

Design

Twenty-nine respondents participated in this study. They were asked the widely used question: ‘Within the past 12 months when seeking health care do you feel your experiences were worse than, the same as, or …

Sustainable Global Medical Mission Work: The Csb/Sju Global Medical Brigade, Tyler J. Bruinsma

Forum Lectures

International medical mission work, especially programs that include undergraduate students are under increasing fire as an unsustainable method for providing care to marginalized populations in developing countries. Medical mission work is often short-sighted and neglects to address the underlying causes of diseases. Annually, the CSB/SJU Global Health Affairs Club plans and executes a "Global Medical Brigade" to Honduras in conjunction with Global Brigades, a 501(c)3 non-profit organization. Global Brigades is different than most medical mission organizations in that it follows a holistic model to address health concerns. Through seven separate "brigades," Global Brigades addresses both immediate health concerns and their …

Exploring Determinants Of Handwashing With Soap In Indonesia: A Quantitative Analysis, Mitsuaki Hirai, Jay P. Graham, Kay Mattson, Andrea Kelsey, Supriya Mukherji, Aidan Cronin

Environmental and Occupational Health Faculty Publications

Handwashing with soap is recognized as a cost-effective intervention to reduce morbidity and mortality associated with enteric and respiratory infections. This study analyzes rural Indonesian households’ hygiene behaviors and attitudes to examine how motivations for handwashing, locations of handwashing space in the household, and handwashing moments are associated with handwashing with soap as potential determinants of the behavior. The analysis was conducted using results from a UNICEF cross-sectional study of 1700 households in six districts across three provinces of Indonesia. A composite measure of handwashing with soap was developed that included self-reported handwashing, a handwashing demonstration, and observed handwashing materials …

Predictors Of Infant Age At Enrollment In Early Infant Diagnosis Services In Kenya., Kathy Goggin, Catherine Wexler, Niaman Nazir, Vincent S. Staggs, Brad Gautney, Vincent Okoth, Samoel A Khamadi, Andrea Ruff, Michael Sweat, An-Lin Cheng, Sarah Finocchario-Kessler

Manuscripts, Articles, Book Chapters and Other Papers

Despite the importance of early detection to signal lifesaving treatment initiation for HIV+ infants, early infant diagnosis (EID) services have received considerably less attention than other aspects of prevention of mother to child transmission care. This study draws on baseline data from an on-going cluster randomized study of an intervention to improve EID services at six government hospitals across Kenya. Two logistic regressions examined potential predictors of "on time" (infant ≤6 weeks of age) vs. "late" (≥7 weeks) and "on time" versus "very late" (≥12 weeks) EID engagement among 756 mother-infant pairs. A quarter of the infants failed to get …

OHSU-PSU School of Public Health Faculty Publications and Presentations

HIV and poverty are inextricably intertwined in sub-Saharan Africa. Economic and livelihood intervention strategies have been suggested to help mitigate the adverse economic effects of HIV, but few intervention studies have focused specifically on HIV positive persons. We conducted three pilot studies to assess a livelihood intervention consisting of an initial orientation and loan package of chickens and associated implements to create poultry microenterprises. We enrolled 15 HIV-positive and 22 HIV-negative participants and followed them for up to 18 months. Over the course of follow-up, participants achieved high chicken survival and loan repayment rates. Median monthly income increased, and severe …

Stigmatization Fo Hiv/Aids: A Cross-Cultural Analysis, Jamie Doctrow

Mahurin Honors College Capstone Experience/Thesis Projects

The Human Immunodeficiency Virus (HIV) is the cause of a public health epidemic that has impacted millions of individuals worldwide. Though medical advances have decreased the number of AIDS related deaths by 42% since the peak year of 2004 (UNAIDS, 2015), many individuals with HIV/AIDS are unaware of their status and are not currently receiving antiretroviral treatment. Many experts have suggested that a significant barrier to HIV/AIDS prevention and treatment is the social stigma that has become attached to the disease. No single cause of this stigmatization has been identified, but a variety of influences may play a role. To …

Inequitable Chronic Lead Exposure: A Dual Legacy Of Social And Environmental Injustice, Tamara Leech, Elizabeth A. Adams, Tess D. Weathers, Lisa K. Staten, Gabriel M. Filippelli

Department of Public Health Scholarship and Creative Works

Both historic and contemporary factors contribute to the current unequal distribution of lead in urban environments and the disproportionate impact lead exposure has on the health and well-being of low-income minority communities. We consider the enduring impact of lead through the lens of environmental justice, taking into account well-documented geographic concentrations of lead, legacy sources that produce chronic exposures, and intergenerational transfers of risk. We discuss the most promising type of public health action to address inequitable lead exposure and uptake: primordial prevention efforts that address the most fundamental causes of diseases by intervening in structural and systemic inequalities.

Gauci, Elli Leontsini, Robert H. Gilman

OHSU-PSU School of Public Health Faculty Publications and Presentations

Background: Taeniasis and cysticercosis are major causes of seizures and epilepsy. Infection by the causative parasite Taenia solium requires transmission between humans and pigs. The disease is considered to be eradicable, but data on attempts at regional elimination are lacking. We conducted a three-phase control program in Tumbes, Peru, to determine whether regional elimination would be feasible.

Methods: We systematically tested and compared elimination strategies to show the feasibility of interrupting the transmission of T. solium infection in a region of highly endemic disease in Peru. In phase 1, we assessed the effectiveness and feasibility of six intervention …

Delinking Investment In Antibiotic Research And Development From Sales Revenues: The Challenges Of Transforming A Promising Idea Into Reality, Kevin Outterson, Unni Gopinathan, Charles Clift, Anthony So, Chantal Morel, John-Arne Røttingen

Faculty Scholarship

1. The current business model for antibiotics is plagued by market failures and perverse incentives that both work against conservation efforts and provide insufficient rewards to drive the development of much-needed new treatments for resistant infection.

2. Many new incentive mechanisms have been proposed to realign incentives and support innovation and conservation over the long term. The most promising of these are based on the idea of delinking rewards from sales volume of the antibiotic — the notion of “delinkage.”

3. Some critical design issues for delinkage remain, such as how to secure access to badly needed new products when …

A Generalized-Growth Model To Characterize The Early Ascending Phase Of Infectious Disease Outbreaks, Cecile Viboud, Lone Simonsen, Gerardo Chowell

Global Health Faculty Publications

Background

A better characterization of the early growth dynamics of an epidemic is needed to dissect the important drivers of disease transmission, refine existing transmission models, and improve disease forecasts.

Materials and methods

We introduce a 2-parameter generalized-growth model to characterize the ascending phase of an outbreak and capture epidemic profiles ranging from sub-exponential to exponential growth. We test the model against empirical outbreak data representing a variety of viral pathogens in historic and contemporary populations, and provide simulations highlighting the importance of sub-exponential growth for forecasting purposes.

Results

We applied the generalized-growth model to 20 infectious disease outbreaks representing …

Hiv Vaccines: Progress, Limitations And A Crispr/Cas9 Vaccine, Omar A. Garcia Martinez

Biology: Student Scholarship & Creative Works

ABSTRACT: The HIV-1 pandemic continues to thrive due to ineffective HIV-1 vaccines. Historically, the world’s most infectious diseases, such as polio and smallpox, have been eradicated or have come close to eradication due to the advent of effective vaccines. Highly active antiretroviral therapy is able to delay the onset of AIDS but can neither rid the body of HIV-1 proviral DNA nor prevent further transmission. A prophylactic vaccine that prevents the various mechanisms HIV-1 has to evade and attack our immune system is needed to end the HIV-1 pandemic. Recent advances in engineered nuclease systems, like the CRISPR/Cas9 system, have …

Maternal, Environmental, And Social Context Predicts Diarrheal Infection Incidence In Young Children In Sundarbans, India, Sohini Mukherjee, Laura M. Glynn

Student Scholar Symposium Abstracts and Posters

Diarrheal infection is the third leading cause of childhood mortality in India and is responsible for 13% of all deaths per year in children under 5 years of age (Lakshaminarayan & Jayalakshmy, 2015). The Sundarbans in West Bengal is amongst the poorest regions of India and is the epitome of abject deprivation and the acute struggle against geographical and socioeconomic challenges. The incidence of diarrhea in this region is considerably high; about 42,000 reported cases occur per month, and one in five diarrhea cases are reported as severe (with blood in stool). In addition, 37% of children hospitalized for ailments …

As no vaccine currently exists for the Chikungunya virus (CHKV), mosquito control and efficient public health campaigns are crucial for the prevention of disease propagation. The purpose of this research project is to identify populations particularly at-risk for acquiring Chikungunya, and to explore the role that cultural attitudes may play in impacting mosquito-borne disease. Due to its geographical structure and climate, Guatemala is an ideal territory for the spread of emerging and re-emerging mosquito-borne diseases. This project was developed by collaborating with the public governmental health clinic in the municipal town of Teculután, in the department of Zacapa in Guatemala. …

Is The United States Prepared For A Major Zika Virus Outbreak?, Lawrence O. Gostin, James G. Hodge Jr.

Georgetown Law Faculty Publications and Other Works

Zika virus has emerged as a global public health crisis with active transmission in the Americas and Caribbean. The World Health Organization (WHO) declared a Public Health Emergency of International Concern (PHEIC), and recently WHO reported there is a scientific consensus that Zika is a cause of microcephaly and Guillain-Barré syndrome (GBS). In the U.S. the Centers for Disease Control and Prevention (CDC) activated its emergency operations center at its highest capacity. President Obama requested $1.86 billion in emergency funding. Shamefully, Congress has yet to appropriate the funding needed for Zika preparedness, and the President has had to reallocate Ebola …
