Bridges2Scale: Testing Implementation Strategies
The goal of this clinical trial is to compare two multifaceted strategies (standard vs enhanced) for scaling Bridges in a two-arm Hybrid III effectiveness-implementation cluster randomized controlled trial (RCT) in adolescent and youths affected by AIDS \[AYaAIDS\] (ages 11-17 years) from 48 schools in the Greater Masaka region of Uganda. The main aims of the clinical trial are: Aim 1. Compare the implementation effectiveness of the standard implementation strategy vs. an enhanced implementation strategy. The investigators will assess fidelity to Bridges (primary implementation outcome) and sustainment of Bridges (exploratory implementation outcome). Aim 2. Determine the clinical effectiveness of Bridges implemented via a standard vs. enhanced implementation strategy. Aim 3: Explore implementation processes, mechanisms, and determinants. Aim 4. Compare the cost and cost-effectiveness of the two implementation strategies. Using an activity-based ingredients approach, the investigators will examine how much each strategy costs to achieve a unit of effect.

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.

Intervention for Virologic Suppression in Youth
The goal of this randomized clinical trial is to test the effect of a technology-based intervention with an Adaptive Treatment Strategy (ATS) among youth living with HIV (YLWH) (18-29 years old). This piloted and protocolized intervention combines: (1) brief weekly sessions with a counselor via a video-chat platform (video-counseling) to discuss mental health (MH), substance use (SU), HIV care engagement, and other barriers to care; and (2) a mobile health application (app) to address barriers such as ART forgetfulness and social isolation. Individuals who are not virologically suppressed will be randomized to video-counseling+app or standard of care (SOC). Through this study, the investigators will be able to: Aim 1: Test the efficacy of video-counseling+app vs SOC on virologic suppression in YLWH.The investigators will compare HIV virologic suppression of those randomized to the intervention vs control arms at 16 weeks via an RCT. Aim 2: Assess the impact of video-counseling+app vs SOC on MH and SU in YLWH. The investigators will evaluate the MH and SU differences between the intervention vs control arms at 16 weeks via an RCT. Aim 3: Explore an ATS to individualize the intervention by assigning the: 1. virologic "non-responders" in the intervention arm to intensified video-counseling+app for 16 more weeks, 2. virologic "responders" in the intervention arm to continue only app use for 16 more weeks. Researchers will compare the characteristics of virologic responders and non-responders to the intervention, individualization of the intervention based on these variables, and linkage to MH and SU treatment services among those in need to see if delivery of care is enhanced and impact on virologic suppression.

Pre- and Post-treatment Lung Microbiota, Metabolome and Immune Signatures at the Site of Disease in Patients With Active Pulmonary Tuberculosis
The diverse microbial communities in different parts of the human body (microbiome) are important for health but understudied in pulmonary tuberculosis (TB), which is the single biggest infectious cause of death in the world. The investigators will study the site-of-disease microbiome (in the lung bronchoalveolar space) in TB cases to investigate how, before TB treatment, metabolic compounds made by microbes affect host biomarkers important for TB control. The investigators will ask this question again at the end-of-treatment and one year later. Specifically, the investigators will sample the lung at the active TB hotspot identified by imaging and compare this to a non-involved lung segment usually in the opposite lung. The investigators will compare the lung microbiome to other sites in the body (i.e. oral cavity, nasopharynx, supraglottis, and gut). A small amount of blood (\~15 ml) will be collected to assess peripheral immunological correlates of the host microbiome. Protected specimen brushings of the lung will be used to explore transcriptomic signatures and how these relate to the lung microbiome. The investigators will also apply these questions to the same number of controls (healthy patients and patients with an alternative diagnoses). This will lay the foundation for clinical trials to evaluate if specific bacteria have diagnostic (e.g., PCR) or therapeutic potential (e.g., antibiotics, prebiotics, probiotics, vaccines) where targeting the microbiome could improve clinical outcomes.

Access to PrEP for MSM: Acceptability and Feasibility in Community-based Clinics in West Africa (CohMSM-PrEP)
This demonstration project will assess the acceptability and feasibility of pre-exposure prophylaxis (PrEP) for men who have sex with men (MSM) as part of a comprehensive HIV prevention package in community-based clinics in West Africa. An interventional, open label, multidisciplinary and multicentre cohort study will be performed in Burkina Faso, Côte d'Ivoire, Mali, and Togo. All MSM enrolled will benefit from a comprehensive HIV prevention package including quarterly clinical examinations, screening and treatment of STIs, screening of HIV, PrEP (daily or on-demand, according the participant's choice), immunisation against hepatitis B, individualised peer-led support (for adherence and prevention), group discussions, condoms, and lubricants.

PrEP My Way: A Hybrid Type 1 Clinical Effectiveness-implementation Trial to Promote PrEP Persistence Among Young Kenyan Women
PrEP My Way is a novel PrEP delivery system consisting of clinic-based PrEP initiation, followed by peer-delivered kits for HIV self-testing, PrEP refills, vaginal swabs for gonorrhea and chlamydia self-sampling, pregnancy tests, and contraception refills, if desired. Based on Social Cognitive Theory, the overall hypothesis is that PrEP My Way will overcome critical stigma and structural barriers that currently limit PrEP use and thus empower young women to promote their sexual health. Preliminary testing of PrEP My Way in Kisumu, Kenya found it to be highly feasible and acceptable, but PrEP use as an oral medication was lower than expected. Now that newer PrEP formulations are becoming available, the team is adding choice of PrEP formulation (i.e., oral tenofovir/emtricitabine, injectable cabotegravir-long acting \[CAB-LA\], or dapivirine ring) as well as choice of adherence support from peers (e.g., SMS \[short message service\], routine check-ins and/or WhatsApp groups) to the intervention. The study team will then test the effectiveness of the augmented PrEP My Way intervention (with and without testing for gonorrhea and chlamydia due to cost concerns) on PrEP persistence in women with ongoing HIV prevention needs (i.e., self-reported desire for PrEP, self-reported HIV risk, condomless sex, and/or multiple sexual partners). The team will also track implementation, service, and client metrics per Proctor's framework and determine cost-effectiveness of the intervention

Video-Intervention to Inspire Treatment Adherence for Life for Adolescents
This a two-arm randomized controlled trial whose objective is to explore the impact of VITAL Start for Adolescents (VS4A), a video-based antiretroviral treatment (ART) adherence intervention, on a range of implementation and effectiveness outcomes. The study will be conducted in health facilities which provide HIV care to teens/adolescents in the Machinga and Balaka districts of Malawi with approximately 900 teens living with HIV and their treatment supporters (dyads). Dyads will be individually randomized on a 1:1 ratio to receive either the intervention or the standard of care. The VS4A intervention is designed to support Information, Motivation, and Behavioral skills (IMB) around adolescent ART adherence as well as strategies for enhancing treatment supporter social support. The intervention consists of: 1) a two-session video package with associated activities that both the adolescent and their treatment supporter will be asked to watch and participate in; 2) ART refill for the adolescent; 3) and intensive adherence counselling for those with a high viral load. The primary outcomes are adoption of the intervention and adolescent viral load suppression. The overall hypothesis is that VS4A will achieve high adoption and improve adolescent viral suppression.

Short-term Steroid Therapy in Patients With P. Jirovecii Pneumonia Due to HIV / AIDS
The treatment guidelines for Pneumocystis pneumonia (PCP) suggest adding 40mg of prednisone (or its equivalent in methylprednisolone) twice per day on days 1 through 5, 40 mg days 6 through 10, and 20 mg daily on days 11 through 21 in subjects with moderate and serious PCP. Steroids have shown to improve clinical outcome and reduction in mortality in HIV-infected patients the effectiveness of adjuvant steroid treatment for PCP has been observed if it starts within the first 24 to 48 hours. Possibly, there is a long-term benefit with their use in the recovery of function and limitation of chronic pulmonary complications; recently, benefits have been observed in decreasing the incidence of Inflammatory Immune Reconstitution Syndrome (IRIS) due to Mycobacterium tuberculosis. On the other hand, steroids could increase the morbidity related to adverse reactions as well as paradoxical worsening of associated herpes virus infection, which are attributed to IRIS or as a result of immunosuppression generated by their use. Recently, it has been shown that gradually steroids withdrawal is not necessary in patients who have received less than 21 days of treatment. This non-inferiority work aims to confirm the null hypothesis that a reduced steroid scheme in patients with moderate PCP (8 days) and severe pneumonia (14 days) is sufficient to limit long-term ventilatory complications and acute postinflammatory syndrome, compared to the conventional 21-day scheme. It also has been hypothesized that it could be associated with fewer cases of IRIS due to herpes virus type 1,2,3 and 8.

Evaluation of a Multi-Component Intervention to Support HIV Testing and Linkage to Services Among MSM in Peru
This study is testing a new program designed to improve access to HIV testing and help connect people with available treatment or prevention services, based on their test result. The version of the program being tested in this study was designed for men who have sex with men (MSM) in Lima, Peru. The program has two main parts: 1) offering HIV testing at venues where people go for sex (called "sex-on-premises venues" or SOPVs), and 2) a text messaging app that shares useful information about HIV treatment/prevention; users can also message back to get support from a healthcare worker. Before doing this study, the researchers worked with community members and healthcare providers in the area to make sure that the HIV testing approach and mobile app were designed in a way that would be engaging and meet their needs. Every Thursday, Friday, and Saturday night during recruitment, the researchers will go to SOPVs popular among the MSM community in Lima and invite people to take an HIV test. On each recruitment date, they will offer one of the following HIV testing options: 1. A rapid HIV test done on-site (participants will get their result right away) 2. An HIV self-testing kit to take home 3. A coupon for a free HIV test at a participating health center 4. Their choice of any one of the previous three options Only one of these options will be offered at a time, depending on the date. The specific HIV testing option offered on each date will be randomly assigned. All participants will receive the mobile app, which will send weekly messages with links to different types of online content (infographics, maps, videos) over the next 3 months. The specific sequence of messages and content will be different depending on the type of HIV test the person received and their HIV test result, once it is known. The study will measure two main outcomes related to the acceptability and feasibility of the program: * The number and percentage of people who accept the program when offered * The number and percentage of participants who continue to engage with the mobile app after 3 months The study will also measure: * overall satisfaction with the app (based on a questionnaire sent at 3 months) * the number and percentage of participants who completed any form of HIV testing after 3 months * the number and percentage of participants who started HIV treatment (out of those with a positive HIV test) * the number and percentage of participants who started HIV pre-exposure prophylaxis, or "PrEP" (out of those with a negative HIV test) All follow-up will be done remotely. Participants will have the app for 3 months. After 3 months, they will get a follow-up questionnaire asking about their experiences with the program. The researchers will keep tracking results related to the HIV treatment/prevention services that people receive for up to 6 months.

Leveraging mHealth to Enable and Adapt CHW Strategies to Improve TB/HIV Patient Outcomes in SA
mHealth solutions designed to support affordable human resources for health, such as community health workers (CHWs), offer the opportunity to reimagine a patient-centered, system-level solution that may radically change care models in low resource settings. The 'leap' of m-health is most potent and practical in settings where desktop-based infrastructure is lacking and hard-wired internet connectivity is unavailable. Investigators have demonstrated the feasibility of mHealth and human resource solutions in South Africa and shown marked improvements in screening, linkage and treatment initiation as well as supporting patient adherence through video DOT (vDOT) and early identification of treatment related toxicity. Investigators' strategies have evaluated solutions for individual cascade steps through TB and HIV smartphone and tablet-based m-health applications implemented by a CHW. This study combines these individual cascade step approaches into an innovative TB/HIV cascade intervention study entitled, "Leveraging mHealth to enable and adapt community health worker strategies to improve TB/HIV patient outcomes in South Africa (LEAP-TB-SA) Trial."

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.
