A Peer-Led Intervention to Improve Postpartum Retention in HIV Care

The purpose of this study is to test the efficacy of a theory-driven peer intervention for pregnant and postpartum women living HIV. The peer intervention is designed to increase self-efficacy, social support, self-regulatory behaviors, and outcome expectancy in order to improve retention in care and viral suppression postpartum. The intervention will consist of face-to-face prenatal educational sessions, starting in early third trimester, and postpartum sessions scheduled up to three months postpartum.

ORCHID: An Online Intervention for Persons With HIV (Miami)

The purpose of this research is to test ORCHID (Optimizing Resilience \& Coping with HIV through Internet Delivery), a skills-building intervention that improves mental health status for persons with HIV, who are at-risk for falling out of care.

A Pragmatic Trial of Two Strategies for Implementing an Effective eHealth HIV Prevention Program (Keep It Up! 3.0)

This study evaluates and compares two implementation strategies of an online HIV prevention intervention: Strategy 1 in which community-based organizations apply, and are selected, for funding to deliver Keep It Up! through current HIV testing programs; and Strategy 2 which is a "direct-to-consumer" model where centralized staff at Northwestern University recruit participants nationally through online advertising campaigns and manage engagement.

Effects of Semaglutide in HIV-Associated Lipohypertrophy

This is a randomized, double-blinded, placebo-controlled trial designed to assess the effect of the GLP-1 receptor agonist, semaglutide, on visceral and ectopic fat, insulin resistance, inflammation markers, and the downstream effect of cardiovascular risk in people with HIV. The primary endpoints will be visceral and ectopic fat changes over the study period. The secondary endpoints will include changes in markers of inflammation, immune activation, gut integrity, and cardiovascular disease risk assessment.

Appalachian Partnership to Reduce Disparities (Aim 2)

By combining two strategies (i.e., peer navigation and mHealth) into a complete, culturally compatible, bilingual intervention to increase the use of needed HIV, STI, and HCV prevention and care services among racially/ethnically diverse GBMSM and transgender women in rural Appalachia. Study Investigators anticipate that participants in the intervention group, relative to counterparts in the delayed-intervention group, will demonstrate increased HIV, STI, and HCV testing.

Prevent TB: Choice Architecture for TPT Delivery

Background: Clinical guidelines and policies often fail to achieve high levels of delivery of intended clinical interventions. The difference in what the investigators know works and what is actually delivered at the clinic-level to patients, is known as the "science-to-service gap." In the realm of tuberculosis (TB) prevention, this gap is reflected in \<20% of TB preventive therapy (TPT) -eligible persons living with HIV (PWH) being offered or initiated on isoniazid preventive therapy (IPT) in many settings. Recent innovation in TPT have brought new pharmacological options allowing for shorter courses, intermittent dosing, or both. The overarching goal of this study is to identify a generalizable approach to overcome current barriers to delivery of TPT in order to achieve high levels of TPT delivery during routine care in public clinics. Multiple approaches are in standard use to change prescribing behavior including in service training, audit and feedback, clinical mentoring, the use of clinical decision aids, and "academic detailing." However, the overall change is generally modest. To achieve a substantial increase in TPT delivery (from current approximately 20% to 60-80%) will require a fundamental change in the approach to selecting patients for TPT - a redesign of the choice architecture of TPT prescribing. Methods: The investigators are proposing a choice architecture that makes prescribing TPT the "default" or standard option and that for TPT not to be prescribed will require a choice by a clinician to "opt-out" of TPT for a specific patient. The investigators are proposing a cluster randomized design to test the choice architecture approach to increasing delivery of TPT. Clinics will be randomized to one of two strategies: (1) standard implementation and (2) choice architecture default TPT. Because of the clinic-level nature of the implementation strategies, all PWH receiving care at a clinic will be exposed to the standard implementation or TPT routinization implementation. Clinical process data will be used to assess the effectiveness of each strategy to determine the proportion of PWH (1) screened for TPT, (2) eligible for TPT, and (3) prescribed TPT. Significance: TB is the leading cause of death among PWH in South Africa and elsewhere on the continent. TPT is a proven intervention to reduce mortality among PWH but is not widely prescribed. This study seeks to identify an implementation strategy to reach optimal TPT prescribing.

Impact of Metformin on Immuno-virologic Parameters in HIV

Non-diabetic, aviremic HIV-infected individuals on antiretroviral therapy (ART) will be randomized to metformin therapy or to observation for 72 weeks. Primary objective is to assess change over 72 weeks in CD4 T cell negative checkpoint receptors (PD-1 and TIGIT). The study will also explore the 72 week impact of metformin on change in carotid intima-media thickness (cIMT) as a surrogate marker of atherosclerosis, on neuropsychological (NP) performance, strength, and change in body composition.

Enhancing the Organizational Social Context to Improve Viral Suppression and Retention in HIV Care

Despite the widespread use of effective antiretroviral therapy (ART), the HIV epidemic continues to impact racial and ethnic minority populations disproportionately. Although Black/African American persons account for 13% of the U.S. population, they account for 41% of new HIV diagnoses and experience the lowest rates of retention in HIV care and viral suppression (VS) compared to other racial/ethnic groups. Structural racism and discrimination (SRD) likely contribute to racial disparities in HIV outcomes. Although the outpatient setting is a vitally important aspect of care provision for people living with HIV (PLWH), there are limited data on the impact of intra-organizational SRD on HIV outcomes. Longitudinal engagement in HIV care is needed for sustained VS and decreased community transmission of HIV. The organizational social context (OSC) includes organizational culture (organizational norms and values that drive quality of care), organizational climate (perception of the culture and how it impacts personal well-being), and workers' attitudes. Using a randomized controlled trial (RCT), we will implement ARC (Accessibility, Responsiveness, Continuity) to improve organizational behavior and reduce racial disparities in HIV outcomes for PLWH. ARC is an evidence-based intervention that uses three strategies (ARC principles, ARC component tools, and ARC mental models) to create OSCs that support the implementation of interventions to improve patient outcomes. Clinics will be randomized to ARC (n = 2) or standard of care (SOC; n= 2). Those assigned to ARC will address SRD occurring at the organizational level affecting care, including referral and treatment patterns for PLWH. A pre-implementation period will be followed by ARC and ARC-associated implementation strategies for 36 months and then a 12-month post-implementation period where we will continue to measure HIV outcomes in both arms. We will compare HIV outcomes, namely VS and retention in care, and intermediate outcomes, such as linkage to mental health treatment and staff turn-over in clinics assigned to ARC and SOC. We will also evaluate whether individual (self-efficacy, perceived discrimination) and organizational factors (OSC and cohesion of OSC measures) mediate the relationship between ARC, intermediate, and HIV outcomes. In preparation to the RCT, we will evaluate baseline OSC measures across 12 HIV clinics in Philadelphia and determine aspects of the OSC associated with VS and retention in care in a multi-level model adjusting for neighborhood SRD, patient-level factors, and clustering of patients nested in clinics and neighborhoods. We will then test the effectiveness of ARC in improving a primary outcome of VS and secondary outcome of retention in care at the end of the implementation period. We will examine the acceptability, sustainability, and cost of implementing ARC in outpatient HIV care. This research will advance understanding of the impact of SRD on HIV treatment outcomes and health services research and the implementation of a disseminable evidence-based practice aimed at reducing SRD.

The ENCHANTMENT HIV Study

Persons with HIV, even those well-treated, are at increased risk for heart disease when compared to the general population. Two hormones called aldosterone and brain natriuretic peptide (BNP), which have been shown to be abnormal in HIV, may be associated with inflammation as well as early changes in structure and function of the heart. This study is being conducted to evaluate whether therapies to block aldosterone and increase BNP levels may reduce the burden and progression of heart failure to improve cardiovascular health.

Peer-led Dynamic Choice HIV Prevention for Women: The Peer-led DCP Pilot Study

This study will refine and pilot test the Peer-led Dynamic Choice HIV Prevention (DCP) intervention in a single-arm pilot trial. The study will test the hypothesis that the Peer-led Dynamic Choice HIV Prevention intervention will be feasible and increase biomedical HIV prevention coverage in the 6 months after receipt of the Peer-led DCP intervention compared to the standard of care in the 6 months prior to intervention implementation.

Peer-led Dynamic Choice HIV Prevention for Women: The Peer-led DCP Randomized Trial

This Hybrid Type 1 cluster randomized trial will test the Peer-led Dynamic Choice HIV Prevention (DCP) intervention compared to standard of care.

ADELANTE: A Randomized Controlled Trial to Improve Engagement in Care for Latinos With HIV

The goal of this study is to test the effectiveness of ADELANTE on viral suppression among Latinos with HIV and viral non-suppression. Participants will receive ADELANTE (5-session, community health worker-delivered, problem-solving intervention) or enhanced care condition (ECC, 5 reminder phone calls). We will evaluate the overall effectiveness of ADELANTE compared with ECC on rates of viral suppression and emergency room visits and hospitalizations. Our hypothesis is that ADELANTE participants will achieve higher rates of viral suppression and will have lower rates of emergency room visits and hospitalizations compared with ECC at 12 months post-randomization.

Observational Pharmaco-Epidemiology Research & Analysis

Greater advances are needed in two separate but related areas in healthcare: 1) the Clinical Decision Support Systems that complement the EHR use in support of routine patient care, population management and disease management; and 2) the use of the point-of-care observational data from the provider-patient encounter that support realworld medical research and healthcare quality measure assessment. Real-world evaluations of treatments of chronic diseases in the context of comorbid conditions and special populations (minorities, women, mentally ill, and those with addiction) are limited. The purpose of the OPERA database is to help address this unmet need in clinical research.

Characteristics and Outcomes of Patients Who Received Etravirine and/or Darunavir

The objectives of this data collection activity are to: 1. Describe the baseline demographics, clinical and laboratory profile of patients who ever received darunavir (DRV) and/or etravirine (ETR), at the time of initiation on DRV and/or ETR; 2. Describe the clinical and laboratory profile of patients who ever received DRV and/or ETR every 6 months from the first data collection point through 2021; 3. Describe dynamics in HIV drug resistance mutations among patients who fail treatment on new regimens including DRV and/or ETR; 4. Describe demographics, clinical and laboratory profile of young adults who transition out of the donation program after the age of 25 years at 12 months after their transition.

Optimizing Tobacco Use Treatment for PLWHA

The advent of anti-retroviral therapy (ART) for people living with HIV/AIDS (PLWHA) substantially improved life expectancy but has also led to the critical need to address modifiable risk factors associated with cancer and cardiovascular disease, such as tobacco smoking. HIV-infected smokers lose more life-years due to tobacco use than they do to their HIV infection. There have been relatively few studies of tobacco use treatments for PLWHA and systematic reviews show that there are insufficient data to conclude that tobacco dependence interventions that are efficacious in the general population are efficacious for PLWHA. Further, many studies in this area have lacked randomization and a control group, infrequently used an intent-to-treat (ITT) approach and biological verification of tobacco abstinence, and lacked post-treatment follow-up.10 What investigators do know thus far is that behavioral interventions and the nicotine patch yield moderate effects on cessation; and 2 recent placebo-controlled trials - one in France and one by this lab - found that varenicline is safe and effective for treating tobacco use among PLWHA, but yield quit rates that are substantially lower than those reported in the general population. Thus, there is a critical need to rigorously test novel ways to optimize tobacco cessation treatment for smokers with HIV.

Efficacy, Acceptability and Safety of Event-driven HIV PrEP Using TAF/FTC in MSM in Thailand and France.

The purpose of this study is to evaluate the efficacy, acceptability, and safety of a simplified event-driven pre-exposure prophylaxis of HIV based on oral TAF/FTC in HIV-uninfected cisgender men who have sex with men (MSM). Primary objective: To assess the efficacy of emtricitabine 200 mg + tenofovir alafenamide 25 mg (F/TAF), taken 2 to 24 hours before sexual intercourse followed by a second dose 24 hours after the first intake, in reducing the risk of HIV acquisition in MSM relative to the background HIV incidence rate.

Combinatorial Therapy to Induce an HIV Remission

Combination approaches will almost certainly be required to generate durable control of HIV in the absence of antiretroviral therapy (a "remission"). In this study, 20 individuals will receive a combination regimen administered during ART and then undergo an analytic treatment interruption (ATI).

An mHealth Intervention to Improve Outcomes for Women With HIV/AIDS

The purpose of this study is: 1. To develop a new mobile health (mHealth) system that will send text messages to remind both pregnant and non-pregnant women with HIV to adhere to their treatment plan (like keeping appointments, fillings prescriptions, and taking their medication) and address individual barriers to HIV care (like stigma, medical mistrust and resilience). 2. The intervention will also include patient navigation and motivational interviewing 2\) Investigators also want to see if the mHealth system is feasible, easily accepted and if it will impact patient health in a positive way.

Measuring Adverse Pregnancy and Newborn Congenital Outcomes

The purpose of this study is to develop a pharmacovigilance (PV) surveillance program to monitor adverse pregnancy and infant outcomes, including the presence of congenital abnormalities, among HIV-positive and HIV-negative women and their infants at clinical sites affiliated with the International Epidemiology Databases to Evaluate consortium (IeDEA).

Robot-Assisted Rehabilitation After HIV-Associated Stroke: Botswana

Today, nearly 37 million people are living with HIV (PLHIV) worldwide and 30 to 40% of them will have neurologic complications leading to disability. Our long-term working hypothesis is that an effective solution for increasing rehabilitation access in Botswana and improving functional outcomes of PLHIV having experienced a stroke with or without HIV uses an affordable robot and mobile health technologies to create a cost-effective intervention strategy. For this project, we test the feasibility of affordable robot therapy.

Sustaining Innovative Tools to Expand Youth-Friendly HIV Self-Testing

Sustaining Innovative Tools to Expand Youth-Friendly HIV Self-Testing (S-ITEST), locally known as 4 Youth by Youth (4YBY) in Nigeria, builds on the investigator's previous efforts, which are detailed in ClinicalTrial ID#: NCT04070287, NCT03874663, and NCT04710784. Many adolescents and young adults (AYA, 14-24 years old) in Nigeria have a substantial HIV risk but do not receive adequate HIV prevention services. While pre-exposure prophylaxis (PrEP), HIV self-testing, sexually transmitted infection (STI) testing, and linkage to AYA-friendly clinical services are essential, they have not been widely implemented or sustained in Nigeria. In this study, the investigators aim to 1) use participatory approaches (i.e., crowdsourcing, designathons, and participatory learning communities (PLC)) to develop sustainability strategies that sustain 4YBY in participating community sites served by recruited community-based organizations; 2) test the effects of the standard 4YBY implementation versus standard with enhanced sustainability strategy on site-level adoption and sustainability of the 4YBY intervention across 24 months in participating community sites (n=40) and community-based organizations (n=20); and 3) characterize and estimate the impact and cost-effectiveness of sustaining 4YBY over time. Guided by youth participatory action research (YPAR), the PEN-3 cultural model, Proctor's Implementation Outcomes Framework, and the Consolidated Framework for Implementation Research (CFIR), this study intends to support community-based organizations in implementing and sustaining the 4YBY intervention to increase the uptake of HIV prevention services while optimizing resource allocation to achieve sustainability in collaboration between the Washington University School of Medicine, the University of North Carolina at Chapel Hill, Georgia State University, George Washington University, Monash University, Wake Forest University School of Medicine, and the Nigerian Institute of Medical Research (NIMR).

Project I Test: Implementing HIV Testing in Opioid Treatment Programs

This study will test two active evidence-based "practice coaching" (PC) interventions to improve opioid treatment programs' (OTPs') provision and sustained implementation of on-site 1) HIV testing and linkage to care and 2) HIV/Hepatitis C virus (HCV) testing and linkage to care among patients seeking/receiving substance use disorder treatment. Aims are: Aim 1: To evaluate the effectiveness of the PC interventions on improving patient uptake of HIV testing in OTPs including the incremental impact of the HIV/HCV intervention on HIV testing. Aim 2: To examine, using mixed-methods, the impact of the PC interventions on the initiation and sustained provision of HIV testing and timely linkage to care. Aim 3: To evaluate the health outcomes, health care utilization, and cost-effectiveness of the PC interventions compared incrementally to one another and to the control condition. Primary Hypothesis: 1. The two PC interventions will result in significantly higher proportions of patients tested for HIV than the information control condition during the "initial impact" period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Primary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary). 2. The HIV/HCV PC intervention will result in significantly higher proportions of patients tested for HIV than the HIV PC intervention during the initial impact period (7-12 months post-randomization or T3), controlling for the proportion of patients tested during the baseline period, T1 (Secondary) and during the "sustained impact" period, 13-18 months post-randomization or T4 (Secondary).
