Harm Reduction in HIV Primary Care for PLWH Who Use Drugs

People living with HIV (PLWH) who use drugs experience significant health disparities including lower rates of retention in HIV care and higher rates of unsuppressed viral load, resulting in secondary infections and increased mortality. The proposed study will used mixed methods to explore (a) the relationship between healthcare providers' attitudes towards working with PLWH who use drugs and providers' acceptance and practice of structural and relational harm reduction; (b) the degree to which relational harm reduction moderates the effect of intersectional stigma experienced in healthcare settings on patients' perceptions of their relationship with providers; (c) the degree to which structural HR moderates the relationship between the patient-provider relationship and clinical outcomes, and (d) whether patient-perceived HR approaches to care are directly associated with HIV clinical outcomes. The study will also use these findings to inform the development and pre-testing of an intervention to operationalize harm reduction in HIV clinical settings, using stakeholder-engaged and human-centered design approaches, presenting a novel path to reducing HIV health inequities for PLWH who use drugs.

Feasibility of Incorporating a Standardized Substance Use Measure With Linked-Brief Intervention Into Routine Psychosocial Care of Adult Childhood Cancer Survivors

The ASSIST Study is designed to explore whether a brief, evidence based substance use screening and counseling approach can be easily integrated into routine survivorship care at St. Jude Children's Research Hospital. During a regularly scheduled psychosocial visit, participants complete the World Health Organization's Alcohol, Smoking, and Substance Involvement Screening Test (ASSIST). This short questionnaire helps identify patterns of use related to tobacco, alcohol, cannabis, prescription medications, and other substances. Survivors whose results show possible risk receive a brief, supportive counseling session during the same appointment. This session uses motivational interviewing techniques to help individuals reflect on their use and consider steps to reduce potential harm. Primary Objective: \- Assess the feasibility and acceptability of integrating a standardized substance use screening and brief intervention protocol into routine psychosocial workflows within a survivorship clinic. Secondary Objective: \- Evaluate the fidelity of delivering a brief substance use intervention to reduce substance use behaviors among survivors.

The Development and Evaluation of a Culturally Grounded ENDS Intervention for Rural Hawaiian Youth

The purpose of this research proposal is to develop and evaluate a culturally grounded, ENDS prevention intervention for rural Hawaiian youth. This will be accomplished through two specific aims. AIM 1 (Years 1-3) are focused on pre-intervention and intervention development. In Year 1, youth focus groups will be conducted to assess the environmental demands related to ENDS use in rural Hawai'i. In Year 2, specific ENDS-related problem situations (i.e., situations that increase risk for ENDS use) will be extracted from the Year 1 focus groups and prioritized through survey methods with 200-250 predominately Native Hawaiian youth across 16 different middle/intermediate schools on Hawai'i Island. In Year 3, five situations found to be the most frequently experienced and/or difficult to manage by youth surveyed in Year 2 will serve as the foundation for the development of narrative scripts. Three of these scripts will be cast and filmed on location on Hawai'i Island by a professional film director, and will be edited into three short films, 6-8 video clips, and 6-8 professional photos or production stills. Similar to the investigators' prior drug prevention research in rural Hawai'i, classroom-based lessons will be created to support the short films. Additional lessons and videos from an evidence-based, culturally grounded substance abuse prevention curriculum for Hawaiian youth (Ho'ouna Pono) will be used to create a modular classroom curriculum. The video clips and professional photography/production stills will be embedded with prevention messaging, and will be used for a social and print media campaign to reinforce the classroom curriculum. AIM 2 (Years 4-5) is to evaluate the ENDS prevention intervention (classroom curriculum plus social/print media campaign) across all middle/intermediate public or public-charter schools (N = 16) and up to 11 different cultural immersion charter schools on Hawai'i Island using a dynamic wait-listed control group design.

Leveraging Social Networks to Increase COVID-19 Testing Uptake

This two-year project will adapt and conduct a trial examining the ability of two recruitment strategies, chain-referral and credible messenger, to reach those who use opioids and other substances in order to increase their uptake of onsite point of care COVID-19 testing that will be delivered in two community based organizations (CBOs): Alliance for Positive Change and Argus Health Inc. In Phase 1, Adapt two implementation strategies to support COVID-19 testing uptake and sustainability, adapting elements of existing efficacious social network-based interventions via a CBPR approach. In Phase 2, we will examine and compare the efficacy of two sets of implementation strategies on (i) reach, (ii) testing uptake, (iii) service delivery (i.e. quarantine, medical care, contact tracing) and (iv) sustainability for individuals who use opioids and other drugs. In Phase 3, Elucidate and compare the system/organizational-, staff-, and individual-level factors that influence implementation (i.e. fidelity, acceptability, feasibility, sustainability) of the strategies to develop a plan for dissemination and scale-up in other CBOs who serve opioid and other substance using individuals in NYC.

A Novel Intervention for Patients With Cancer

This research study is being done to develop an intervention for psychological symptoms that patients diagnosed with cancer may experience. Psychological symptoms may include thoughts, feelings, emotions, and memories The names of the study intervention and research activities involved in this study are/is: * Acceptance \& Commitment Therapy (ACT) for Cancer (involving 6 sessions with a licensed clinical psychologist) * Questionnaires * Post-study interview Consistent with the NIH Stage Model for Behavioral Intervention Development, the investigators have adapted an existing, empirically-validated intervention, Acceptance and Commitment Therapy (ACT), to address substance use disorder risk during cancer care. The core components of ACT are particularly well-suited to address the psychological processes underlying opioid misuse in individuals treated for cancer pain. The overarching aim is to assess the feasibility and acceptability of the intervention by conducting a randomized pilot trial of the revised intervention ("ACTION") for cancer patients on opioid therapy, and at risk for SUD.

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.
