Identifying Major Sources Of Leptospira Interrogans In San Juan Bay And Río Grande De Loíza Estuaries Of Puerto Rico, Logan Mccullers, Dave Bachoon

Biology Theses

This study evaluated the presence of pathogenic Leptospira interrogans, potential carriers, and environmental factors influencing their occurrence in the San Juan Bay Estuary (SJBE) and Río Grande de Loíza (RGDL) watersheds of Puerto Rico from 2024–2025. Detection of this pathogen from water samples was performed using the lipL32 PCR assay. The likely hosts of L. interrogans were determined using fecal source tracking (FST) assays for human (HF-183), canine (BacCan-UCD), equine (HoF597), and rat mitochondrial DNA NADH dehydrogenase subunit 2 gene (RatMt) markers. In 2024, 91 samples were collected (March: 50; June: 41), and in 2025, 124 samples were collected …

A Novel Approach To Hiv Testing: Group Harm Reduction And Testing For High Risk Women In Nj, Gabrianna A. Andrews

Rowan-Virtua Research Day

Outreach programs have been implemented aimed at providing healthcare to minority populations and those considered high-risk for acquiring HIV. Variables such as these cause hesitance in community members, preventing HIV screenings and adherence to follow-ups. This study provides and evaluates a new approach: group HIV testing. Data was collected from 6/2/2023 to 4/19/2024 by surveying participants at the end of the interaction. 87.5% of participants rated their care at the mobile clinic as ‘Excellent’, 8% as ‘Very Good’, and 4.5% as ‘Good’. 95.6% of participants ranked Group Harm Reduction Counseling as ‘Definitely’ helpful. 84.4% of participants did not find that …

School of Nursing & Midwifery, East Africa

Background

Adequate sexual and reproductive health literacy (SRHL) among young people has been linked to informed sexual behaviours. Studies on SRHL have largely been conducted among the general adolescent population. Little is known about youth aged 15-24 years living with human immunodeficiency virus (YLHIV). There is a possible lack of SRHL in this population, considering the high rate of teenage pregnancies and unprotected sex reported by YLHIV. This study aimed to assess the prevalence and associated personal and environmental factors for SRHL among YLHIV at a high-volume urban HIV Clinic in Uganda.

Methods

Through a cross-sectional survey, YLHIV receiving routine …

Food Insecurity And Dietary Restrictions, Courtney Williams, Savana Rodriguez, Tiffany Guerrero, Stephen Acheampong, Vanesa Pizutelli

Rowan-Virtua Research Day

According to the USDA Food Insecurity affects around 10.2 percent of the US population as of 2021. For families that have members with certain dietary restriction such as, but not limited to diabetes, hypertension, gluten intolerance, lactose intolerance, and food allergies, the challenge of securing food becomes an even greater burden with having to navigate food banks or discount stores that may not offer food items that meet their dietary requirements. Families with dietary restrictions often face greater food insecurity and less access to food. More research is needed to understand the challenges families with dietary restrictions face regarding food …

The Effect Of An Educational Handout On Knowledge, Awareness And Attitudes Of Pre-Exposure Prophylaxis (Prep) Among Participants At A Needle And Syringe Exchange Site, Mckenzie Buckel

DNP Projects

Background: In 2018, the total number of HIV cases in the United States was 1.2 million. Almost 186,500 of these cases were attributed to intravenous drug use. With the adherence to pre-exposure prophylaxis (PrEP) there is approximately a 49% decrease in the rates of HIV among people who inject drugs and the most significant barrier to PrEP among this population is a lack of awareness and knowledge.

Objective: The purpose of this study was to determine participants’ of a needle and syringe exchange site knowledge, awareness and attitudes of PrEP after reviewing an educational handout about PrEP.

Methods: A quasi …

Lgbtq+ Health Disparities: Healthcare Intervention, Kara Steinbrecher

The Eleanor Mann School of Nursing Undergraduate Honors Theses

The lesbian, gay, bisexual, transgender, and queer (LGBTQ+) community has carried the burden of countless health disparities throughout its history tied to discrimination, bias, prejudice, and stigma. LGBTQ+ individuals are disproportionately at higher risk for substance abuse, sexually transmitted diseases, cardiovascular disease, mental illness, suicide, and unequal access to healthcare, related to social stigma and bias that exists in healthcare itself. The purpose of this systematic literature review is to analyze existing health disparities among the LGBTQ+ population in the United States and the efficacy of various interventions of health care professionals to reduce them. Twenty-one articles from multiple online …

Anti-Vaxxers: Parents Fighting Science, Katie West

Symposium of Student Scholars

Immunizing children helps protect the health of our community, especially those people who cannot be immunized. Yet, since 1996 after a study was released that linked autism to vaccinations, there has been a trend of parents refusing to vaccinate their children. What are the demographics of the parents who believe their children are better off without vaccines? By knowing where these parents live and what decisions they make for their children’s education, counties and medical professionals can provide education and address their concerns.

My research involves data on 116,141 kindergarten classes from 2000-2015 in California. The two vaccine exemption options …

The Role Of Nutrition In Promoting Gut Health And Treating Chronic Illness Through The Attenuation Of Inflammation, Allison Dalton

HCA Healthcare Journal of Medicine

Over the millennia, the human body and microorganisms such as bacteria, viruses, archaea, protozoa and parasites have coevolved together forming an intimate relationship. These microorganisms are found on the skin, in the mouth, genitourinary tract and most abundantly in the large intestine of the digestive tract. States of microbial dysbiosis contribute to chronic inflammation, which can lead to the pathogenesis and progression of numerous diseases. Micro- and macro-nutrients as well as dietary patterns like the Mediterranean diet can help improve health outcomes.

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Multiple Myeloma Baseline Immunoglobulin G Level And Pneumococcal Vaccination Antibody Response, Michael A. Thompson, Martin K. Oaks, Maharaj Singh, Karen M. Michel, Michael P. Mullane, Husam S. Tarawneh, Angi Kraut, Kayla J. Hamm

Journal of Patient-Centered Research and Reviews

Infections are a major cause of morbidity and mortality in multiple myeloma (MM), a cancer of the immune system. Vaccination clinical efficacy endpoints have not been demonstrated, and there are limited data on surrogate markers of efficacy. This pilot study evaluated sequential immunologic markers after standard pneumococcal vaccination (PV) in patients with MM and non-MM controls. Vaccination was standard for PV (PCV13 or PPV23), with laboratory testing at baseline and at 2, 4, 12 and 24 weeks after vaccination. Immunoglobulin G (IgG) antibodies to pneumococcal antigens were detected by ELISA. Prevaccination total IgG levels and IgG subclass levels were also …

Trinidad & Tobago : Hiv Epidemic, Madison Caldwell

Global Public Health

Trinidad and Tobago are twin islands located in the Caribbean off the coast of Venezuela. In the recent years since about 1990, citizens of this country have been greatly affected by the HIV epidemic. HIV stands for human immunodeficiency virus and is spread through infected seman, blood, or vaginal fluids usually through sexual intercourse. As this virus continues to progress in the body, it will eventually turn into AIDS, which stands for acquired immunodeficiency syndrome. Once HIV progresses to AIDS, the outcome is ultimately fatal, hence why there is a dire need to promote awareness and methods of intervention to …

Namibia : Hiv As A National Issue, Elisabeth Vlasak

Global Public Health

Namibia is located on the southwestern coast of Africa, bordering Angola, Botswana, Zambia, South Africa, and the Atlantic Ocean. Namibia has a population of 2,265,000, as of 2016. Namibia has many challenges, including food insecurity and malnutrition, access to health services, unequal distribution of wealth, but HIV/AIDS is one of the country’s leading challenges. It is estimated that the overall adult infection rate of HIV/AIDS is 15.4% and it is the leading cause of death in Namibia. Adults ages 18-24 are the most at-risk for the disease. Some of the major risk factors are declining condom use, misinformation, social stigma, …

A Model For Hiv Disclosure Of A Parent's And/Or A Child's Illness, Gary J. Burkholder Jr, Grace Gachanja

Walden Faculty and Staff Publications

HIV prevalence in Kenya remains steady at 5.6% for adults 15 years and older, and 0.9% among children aged below 14 years. Parents and children are known to practice unprotected sex, which has implications for continued HIV spread within the country. Additionally, due to increased accessibility of antiretroviral therapy, more HIV-positive persons are living longer. Therefore, the need for HIV disclosure of a parent's and/or a child's HIV status within the country will continue for years to come. We conducted a qualitative phenomenological study to understand the entire process of disclosure from the time of initial HIV diagnosis of an …

Cus M! Let’S Go!: The Flourishing Of Bali’S Komunitas Gay In The Hiv/Aids Crisis, Ikaika Ramonès

Independent Study Project (ISP) Collection

This paper draws on approximately one month of field research with two Indonesian Non-Governmental Organisations (NGOs), exploring how Bali’s komunitas gay has been affected by, reacted to, proactively combated, and even transcended the ongoing HIV/AIDS epidemic. This paper first situates the argument by explaining the uniqueness of Bali as a site of HIV/AIDS resurgence and centre of gay life in Indonesia. In this context, the paper discusses the observed phenomena, testimony of experiences from collaborators, and the role one of these NGOs plays in the community. This paper argues against the commonly-held static and victimizing notion that the HIV/AIDS crisis …

The Effects Of Vitamin D Supplementation On Influenza, Jonah M. Spoerndle

Williams Honors College, Honors Research Projects

Recently the role of vitamin D in other non-classical capacities has been evaluated. One of these non-classical vitamin D roles is assisting in maintaining proper immune system health. One disease that has a great effect on the immune system is influenza. Vitamin D helps to prevent and limit influenza by moderating the inflammatory cytokines as well as promoting the production of monocytes that help destroy the invading materials. Through the use of vitamin D supplementation the recommended daily amount of vitamin D can be assured and optimal health could be achieved. The purpose of this project was to design a …

A Rhetorical Analysis Of The Rethinking Aids Website, Jennifer Dettmann

Journal of Undergraduate Research at Minnesota State University, Mankato

A group of scientists known as the Group for Scientific Reappraisal of the HIV-AIDS hypothesis created a web site title, Rethinking AIDS. The group behind the web site argues that AIDS is not a sexually transmitted disease. They even question the existence of the virus entity. My analysis is driven by the critical question: Does the web site construct a reality that affectively alters our perception of HIV-AIDS? In order to answer this question, Goodnight and Poulakos 1981 article, Conspiracy rhetoric: from pragmatism to fantasy to public discourse (Western Journal of Speech), will be utilized.

Gender Disparities In Access To Hiv Testing And Antiretroviral Treatment Services, Wyatt Lombard Smith

Independent Study Project (ISP) Collection

Throughout a six-week practicum period at TASO Mulago in Kampala, Uganda and St. Francis Naggalama Hospital in Naggalama, Uganda, the researcher aimed to find methods to increase male engagement in all facets of comprehensive HIV/AIDS care. Women and children generally receive most global attention on the issue of HIV/AIDS in Uganda but men are beginning to demand more attention. Antiretroviral treatment has been critical in allowing countless people to live functionally with HIV but many research projects have hypothesized that delayed access to HIV/AIDS treatment and prevention methods has resulted in men exhibiting higher mortality rates upon initiation of this …

Implementing Incentive-Based Hiv Interventions In Zambia: The Compact Model, Sam Kalibala, Waimar Tun, Chabu Kangale, Jill Keesbury, Ray Handema, Mwaka Monze

HIV and AIDS

The Population Council received a cooperative agreement from USAID to implement the Community Mobilization for Preventive Action (COMPACT) project, to develop and determine the feasibility of “community compacts” as an innovative approach to prevent HIV in Zambian communities. The aim is to mobilize the communities through a capacity-building process that enables them to identify HIV prevention targets, develop interventions to achieve those targets, and measure the results. This study determined baseline levels of key indicators related to HIV, sexual behaviors, gender-based violence, alcohol abuse, and reproductive health. These baseline measures will be compared with midline and endline levels to assess …

Motivations For Entering Volunteer Service And Factors Affecting Productivity: A Mixed Method Survey Of Steps-Ovc Volunteer Hiv Caregivers In Zambia, Jessica Price, Tina Moyo, Stephanie Topp, Drosin Mulenga, Mardieh Dennis, Mathew Ngunga

HIV and AIDS

This study by the Population Council and the Zambia-Led Prevention Initiative was designed to examine the motivations of individuals volunteering as STEPS-OVC caregivers; to explore their experiences in service, including perceived barriers to carrying out their volunteer work and if, and how, their expectations for volunteering had been met or not; to assess individuals’ intent to continue caregiving; and to ascertain factors associated with volunteer productivity. Two main findings stand out from this study: that communitarian and religious helping values were virtually universal in the study population, and that a majority of the volunteers indicated economic and material interests and …

The Community Mobilization For Preventive Action (Compact) Project In Zambia: A Midline Evaluation, Waimar Tun, Chabu Kangale, Scott Geibel, Meredith Sheehy, Ray Handema, Mwaka Monze

HIV and AIDS

The Population Council and its partner, Project Concern International, implemented the Community Mobilization for Preventive Action (COMPACT) HIV-prevention program in Zambia. The program works with communities to develop “compacts” through a participatory, community-led process, and assists them in working toward reaching HIV-related “benchmarks,” intended to result in a reduction in HIV-related risk behaviors and harmful norms and ultimately contribute over time to the reduction of HIV incidence. This mid-term evaluation in four of six COMPACT communities indicates that COMPACT is improving some HIV-related behaviors and attitudes, particularly those related to gender norms, multiple sex partnerships, and alcohol abuse. The report …

Kalkidan ('Promise'): Addressing Marital Transmission Of Hiv In Ethiopia, Banchiamlack Dessalegn, Annabel Erulkar

Poverty, Gender, and Youth

This program brief describes a Population Council initiative in three low-income areas of Ethiopia. Kalkidan (Amharic for “Promise”) is a three-year program designed to increase discussion and information-sharing on HIV and related topics between marital partners; to promote HIV prevention and health service utilization within marriage, including prevention of mother-to-child transmission (PMTCT) of HIV; and to build husbands’ support of their wives, as well as investment in their health and that of their children. Kalkidan recruits and trains community-based mentors to lead parallel discussion groups of husbands and wives, who periodically come together for joint sessions. The Population Council is …

Developing A Preference Assessment Tool For Use Among Minority And Low Literacy Primary Care Patients, Sarah T. Hawley, Maria Jibaja-Weiss, Partha Krishnamurthy, Sally W. Vernon, Natoshia Hebert, Robert Volk

Journal of Health Disparities Research and Practice

Incorporating patients’ preferences into healthcare decisions has been identified as one mechanism for reducing health disparities. Some research suggests that providers need to tailor medical recommendations to the preferences of their patients. Yet there are few tools to facilitate clarification of preferences for health services. This paper reports the process of testing an innovative preference elicitation technique—conjoint analysis—among minorities and low literacy patients using the example of colorectal cancer (CRC) screening. CRC screening exemplifies preference-sensitive healthcare as there exist several screening options. However, screening rates among minorities are low. Better methods for preference assessment could improve patient-provider communication and increase …

Health Literacy As A Contributor To Immigrant Health Disparities, Jennifer B. Kimbrough

Journal of Health Disparities Research and Practice

The ability to obtain, understand and use the information needed to make wise health choices is known as health literacy. Low health literacy among members of populations with poor reading skills, limited mastery of the English language, members of ethnic or cultural minorities, and immigrants is likely a major contributor to health disparities in the US (Agency for Health Care Policy and Research 1997). A series of focus groups with East-Asian, African, Central and South American immigrants was conducted to better understand the perceptions of immigrants seeking health care services in an urban North Carolina county. Participants’ responses are reported …

A Geospatial Analysis Of Cdc-Funded Hiv Prevention Programs For African Americans In The United States, G. A. Gilliam, Carol L. Hanchette, Kieran J. Fogarty, Deborah A. Gibbs

Journal of Health Disparities Research and Practice

Given the increase in HIV/AIDS infection rates among racial and ethnic minorities, particularly African Americans, this study was undertaken as part of a larger research effort to examine the distribution of HIV prevention services focusing on African American populations within the United States. Data were gathered via a national survey of community-based organizations (CBOs) funded by the Centers for Disease Control and Prevention (CDC). A geocoded national database was constructed to identify, locate, and map these HIV prevention programs. A total of 1,020 CBOs responded to the survey, yielding a response rate of 70.3%. These CBOs administered a total of …
