Preparing To Break Barriers: A Mixed Methods Exploration Of The Knowledge, Attitudes, And Perceptions Of Hiv, Prep, And Hiv Risk Behaviors Among Women Of Color In Miami, Florida, Amanda C. Ichite

FIU Electronic Theses and Dissertations

The U.S. HIV epidemic is characterized by regional, racial, and ethnic disparities. HIV rates are disproportionately higher in the South and Black and Hispanic populations are most impacted. Moreover, the intersectional identity of being a Black or Hispanic woman living in the South has been associated with profound disparities in HIV impact. Prior to the advent of the biomedical HIV prevention tool pre-exposure prophylaxis (PrEP) in 2012, women were limited in their options for female-controlled HIV prevention strategies. Despite the proven efficacy of PrEP, utilization in women is significantly lower than other at-risk groups. In the present study, secondary analysis …

Impact Of The Covid-19 Pandemic On The Care Continuum Of Youth Living With Hiv: Qualitative Study Of The Scale It Up Program Clinical Sites, Tyra Dark, Sitaji Gurung, Mary Dooley, Kit N. Simpson, Seyram A. Butame, Sylvie Naar

Publications and Research

The study objective was to explore the impact of COVID-19 pandemic restrictions on the clinics’ ability to provide continuous healthcare services to youth (15–24 years) living with HIV (YLWH). One focused semi-structured interview was conducted with each HIV clinic site—resulting in ten interviews. Data were analyzed using thematic analysis techniques assisted by NVIVO coding software and themes indicating barriers and facilitators to providing uninterrupted healthcare were elicited. Six themes were identified that affected the care continuum of YLWH: Timeframe of clinic preparation to address COVID-19 restrictions; impact on treatment cascade monitoring data; impact on patient care; impact on staff and …

Emerging Viral Diseases: Generation Z'S Outlook, Ian Mcwhorter

Honors Projects

Generation Z differs notably from previous generations like Baby Boomers or Generation X. In recent years, young adults have been persisting through the COVID-19 pandemic, though not unscathed. This paper seeks to answer the following question: How does Generation Z differ in its outlook on Viral diseases compared to previous generations? Using a series of three surveys conducted on three seperate Viral diseases (HIV, Zika, and COVID 19), it was found that while Generation Z has improved in its ability to combat Viral outbreaks due to factors like high digital literacy, other factors such as poorer mental health show that …

Feasibility Of Using Electronic Health Records For Cascade Monitoring And Cost Estimates In Implementation Science Studies In The Adolescent Trials Network For Hiv/Aids Interventions, Tyra Dark, Kit N. Simpson, Sitaji Gurung, Amy L. Pennar, Marshall Chew, Sylvie Naar

Publications and Research

Background:One of the most difficult areas in the fight against HIV/AIDS is reaching out to youth aged 13 to 24 years. The proportion of youth living with HIV/AIDS on antiretroviral therapy (ART) and who are virally undetectable is low, highlighting significant challenges for reaching the Joint United Nations Program on HIV targets.

Objective:This study aimed to assess the feasibility of obtaining key clinical indicators and monitoring treatment, viral suppression, and retention components of the youth HIV treatment cascade in Adolescent Trials Network for HIV/AIDS Interventions clinics using electronic health record (EHR) downloads and to provide baseline characteristics for the study …

Examining The Effects Of Individual And Neighborhood Factors On Hiv Transmission Risk Potential Among People With Hiv, Semiu Olatunde Gbadamosi

FIU Electronic Theses and Dissertations

HIV transmission risk significantly increases in late-diagnosed HIV and at HIV viral load (VL) >1500 copies/mL. The objective of this dissertation was to examine factors associated with HIV transmission risk potential for persons with HIV (PWH) using measures of time from HIV infection to diagnosis and trajectories of VL suppression. Additionally, we sought to determine whether a single yearly VL measure—the current standard to track the HIV epidemic in the United States—is reliable in assessing viral suppression for PWH. The first study estimated the distribution of time from HIV infection to diagnosis in Florida using a CD4 depletion model and …

Decision-Analytic Models Using Reinforcement Learning To Inform Dynamic Sequential Decisions In Public Policy, Seyedeh Nazanin Khatami

Doctoral Dissertations

We developed decision-analytic models specifically suited for long-term sequential decision-making in the context of large-scale dynamic stochastic systems, focusing on public policy investment decisions. We found that while machine learning and artificial intelligence algorithms provide the most suitable frameworks for such analyses, multiple challenges arise in its successful adaptation. We address three specific challenges in two public sectors, public health and climate policy, through the following three essays. In Essay I, we developed a reinforcement learning (RL) model to identify optimal sequence of testing and retention-in-care interventions to inform the national strategic plan “Ending the HIV Epidemic in the US”. …

Age-Associated Gut Dysbiosis, Marked By Loss Of Butyrogenic Potential, Correlates With Altered Plasma Tryptophan Metabolites In Older People Living With Hiv., Smita Ghare, Richa Singhal, Vaughn Bryant, Sabina Gautam, Chanakya Charan Tirumala, Praneet Kumar Srisailam, Andrea Reyes-Vega, Dushan Ghooray, Craig J. Mcclain, Kristi Hoffman, Joseph Petrosino, Kendall Bryant, Varand Govind, Ronald Cohen, Robert L. Cook, Shirish Barve

Faculty Scholarship

Background:

Imbalance in tryptophan (TRP) metabolism and its neuroactive metabolites, serotonin and kynurenine (KYN), is a known pathogenic mechanism underlying neurocognitive impairment. Gut microbiota plays an important role in TRP metabolism, and the production of these neuroactive molecules affects neurocognitive function. Although both HIV infection and normal aging independently induce gut dysbiosis and influence TRP metabolism, their interactive effects on compositional/functional changes in gut microbiota and consequent alterations in TRP metabolites remain largely undetermined.

Methods:

Older people living with HIV infection (PLWH, aged 50–70 years, n = 22) were enrolled in this cross-sectional pilot study. Metagenomic analysis of fecal microbiome …
