Factors That Influence Perception Of Hiv Risk And Willingness To Use Pre-Exposure Prophylaxis In People Who Inject Drugs, Daria Egorova, Anny Fenton, Kinna Thakarar
Journal of Maine Medical Center
Introduction: Sexual and injection behaviors increase the risk of HIV transmission in people who inject drugs (PWID). We aimed to determine the prevalence of sexual and drug behaviors that increase HIV risk in PWID hospitalized for infections related to injection drug use in Maine. We also examined factors that influenced their perception of HIV risk and willingness to take pre-exposure prophylaxis (PrEP).
Methods: We surveyed 101 PWID with infections related to injection drug use who were hospitalized at 4 hospitals in Maine. T-tests assessed differences in means of bacterial infection risk scores and willingness to take PrEP based on different …

Human APOBEC3 (apolipoprotein B mRNA-editing catalytic polypeptide-like 3) enzymes are capable of inhibiting a wide range of endogenous and exogenous viruses using deaminase and deaminase-independent mechanisms. These enzymes are essential components of our innate immune system, as evidenced by (a) their strong positive selection and expansion in primates, (b) the evolution of viral counter-defense mechanisms, such as proteasomal degradation mediated by HIV Vif, and (c) hypermutation and inactivation of a large number of integrated HIV-1 proviruses. Numerous APOBEC3 single nucleotide polymorphisms, haplotypes, and splice variants have been identified in humans. Several of these variants have been reported to be associated …
Neurocognitive Impairment In People Living With Human Immunodeficiency Virus (Hiv): Risk Factors And Mortality, Zaeema Naveed
Neurocognitive Impairment In People Living With Human Immunodeficiency Virus (Hiv): Risk Factors And Mortality, Zaeema Naveed
Theses & Dissertations
Despite the widespread use of combination antiretroviral therapy (cART), HIV-associated neurocognitive impairment (NCI) persists in people living with HIV (PLWH) with clinical and public health implications. Studies have generated inconsistent results regarding etiological factors for NCI in PLWH and a brief user-friendly predictive tool is desirable in clinical practice to assess the probability of having NCI in PLWH. Furthermore, factors associated with clinically meaningful decline in neurocognitive status and survival disadvantage for patients with NCI are understudied in the post-cART era. The goal of this dissertation was to investigate factors associated with baseline NCI and neurocognitive decline and the association …
Neural Oscillatory Activity Serving Sensorimotor Control Is Regulated By The Mitochondrial Redox Environment In Health And Disease, Rachel Spooner
Neural Oscillatory Activity Serving Sensorimotor Control Is Regulated By The Mitochondrial Redox Environment In Health And Disease, Rachel Spooner
Theses & Dissertations
Despite effective regimens of combination antiretroviral therapy, individuals with HIV are still at higher risk for developing forms of cognitive impairment, with one of the most common behavioral abnormalities to manifest being motor dysfunction. This is an important consideration, as deficits in motor control likely contribute to higher-order cognitive impairments, which together, lead to functional dependencies in the ever-growing aging population of HIV-infected adults. While the neuroanatomical bases of motor dysfunction have recently been illuminated in people living with HIV (PLWH), there remains an open question regarding the molecular processes supporting the circuit-level neuronal dynamics that potentially serve these behavioral …

Development Of Long-Acting Antiviral Drug Nanoformulations, Denise Cobb
Theses & Dissertations
Antiretroviral therapy (ART) has improved the quality and duration of life for people living with human immunodeficiency virus (HIV) infection. However, opportunities to improve its profile abound. ART is limited by putative viral reservoir penetrance, emergence of viral mutations, inherent toxicities, and regimen non-adherence. These highlight the need improved drug delivery schemes. Previously, our lab has demonstrated that targeting mononuclear phagocytes for antiretroviral drug delivery extends drug half-life and improves penetrance into viral reservoirs, addressing these limitations of ART. Herein, we developed synthetic and biologic antiretroviral (ARV) drug nanocarriers improve the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of ARVs through …
Multimodal Neuroimaging Of Hiv And Aging, Brandon Lew
Multimodal Neuroimaging Of Hiv And Aging, Brandon Lew
Theses & Dissertations
HIV infection remains a significant contributor to disease burden, and with the success of antiretroviral therapies, the population of people with HIV is aging. A growing literature suggests a relationship between HIV-infection and a profile of age advancement, most notably in molecular studies of epigenetics. However, despite the widely-known high prevalence of HIV-related brain atrophy, functional deficits, and HIV-associated neurocognitive disorder (HAND), epigenetic age advancement has not been linked to HIV-related changes in neuroimaging metrics.
We applied three neuroimaging methods, structural MRI, resting state functional MRI, and resting state MEG, to study the brain structure and function of 121 virally-suppressed …
Simian Varicella Virus Antibody Response In Recombinant Svv-Siv Immunized Primates, Kiser Horne
Simian Varicella Virus Antibody Response In Recombinant Svv-Siv Immunized Primates, Kiser Horne
Honors Theses
Since its emergence in the early 1980’s HIV has killed approximately 32 million people, and continues to kill over half a million people every year. Significant research into potential vaccines and cures for HIV has been ongoing for decades but has been largely unsuccessful. One of the more promising technologies that is being investigated to develop an HIV vaccine is recombinant vaccine technology. The study presented in this thesis aims to use simian varicella virus (SVV) and simian immunodeficiency virus (SIV) to act as a model for recombinant vaccine development. If a recombinant SVV-SIV vaccine can be proven safe and …

Hiv Tat Protein Activates Plasma Kallikrein-Kinin System In Hiv-1 Tat Transgenic Mice, Logan Sneed
Honors Theses
Human Immunodeficiency Viruses are a group of lentiviruses that have seen a lot of study ever since their discovery. HIV-1, the most common and virulent form of the virus, has proven to be quite deadly when untreated, so any research into the mechanisms of HIV pathogenesis and replication could have major medical applications all over the world. HIV-1 is a sexually transmitted virus that compromises the hosts immune system and eventually leads to the patient developing AIDS, a life-threatening condition that nearly half of people infected with HIV will develop within ten years. Our study sets out to determine exactly …
Intimate Partner Violence Is A Barrier To Antiretroviral Therapy Adherence Among Hiv - Positive Women: Evidence From Government Facilities In Kenya, Bornice C. Biomndo, Alexander Bergmann, Nils Lahmann, Lukoye Atwoli
Intimate Partner Violence Is A Barrier To Antiretroviral Therapy Adherence Among Hiv - Positive Women: Evidence From Government Facilities In Kenya, Bornice C. Biomndo, Alexander Bergmann, Nils Lahmann, Lukoye Atwoli
Internal Medicine, East Africa
Introduction: Intimate Partner Violence (IPV) is linked to low engagement with HIV management services and adverse clinical outcomes, including poor ART adherence. In sub-Saharan Africa, studies on pregnant/postpartum women and transactional sex workers have produced divergent evidence regarding IPV’s association with poor ART adherence. We investigate this association among a broad group of women.
Methods: We sampled 408 HIV-positive women receiving free ART from different types of HIV clinics at government health facilities, assessing for IPV exposure by a current partner, ART adherence rate, and other factors that affect ART adherence (e.g. education, disclosure). ART adherence rates were measured using …
Food Insecurity Is Associated With Nonalcoholic Fatty Liver Disease, Cognitive Impairment, And Immune Activation In People Living With Hiv, Javier A. Tamargo
Food Insecurity Is Associated With Nonalcoholic Fatty Liver Disease, Cognitive Impairment, And Immune Activation In People Living With Hiv, Javier A. Tamargo
FIU Electronic Theses and Dissertations
Food insecurity (FI) is a socioeconomic condition characterized by inadequate access to enough food and nutrition to sustain health and wellbeing. Food insecurity is a risk factor for chronic and age-related conditions, raising concerns for the aging population of people living with HIV (PLWH), in whom food insecurity is disproportionately prevalent. PLWH are at increased risk of nutrition-related complications and chronic co-morbidities, thus food insecurity may exacerbate adverse health outcomes in this population. This study investigated whether food insecurity was associated with nonalcoholic fatty liver disease (NAFLD), cognitive impairment, and immune activation among socioeconomically disadvantaged adults living with and without …

Evaluating Racial And Ethnic Disparities In Access To Primary Care Among Gay And Bisexual Men In The Us, A Population At High-Risk Of Hiv Infection, Jessica S. Kiernan, April D. Kimmel
Graduate Research Posters
BACKGROUND: 69% of new HIV diagnoses in the US are among gay and bisexual men, with disparities by race and ethnicity. Primary care providers increasingly provide HIV prevention. Racial and ethnic disparities in primary care access are well-documented, but their persistence among gay and bisexual men is unknown. We examined racial and ethnic disparities in access to primary care among this population.
METHODS: We used nationally representative person-level sociodemographic, health status and utilization data, and data on organizational- and socially determinant barriers to care, from the National Health Interview Survey, 2013-2018. Outcomes were: 1) general physician visit
RESULTS: The sample …
