The long-term goal of this project is to improve HIV and substance use outcomes and reduce recidivism for HIV+ substance users released from jail. The overall objective of the proposed R34 project is to develop and pilot test a multi-sector community-clinic collaborative intervention that can subsequently be implemented on a larger scale (as part of a future R01) to achieve this goal. Our central hypothesis is that HIV+ substance users released from jail can successfully overcome obstacles to re-entry and continuity of HIV care with individualized, culturally competent assistance in navigating both social and medical services. Aim 1: Develop and refine a collaborative CHW and re-entry program intervention that targets HIV outcomes, substance use and recidivism in HIV+ jail releasees. Aim 2: Conduct a pilot randomized controlled trial comparing the collaborative intervention (n=40) compared to treatment as usual (n=40) in HIV+ substance users released from jail.

OEF/OIF/OND war Veterans have unique post-deployment care needs that the VA is striving to understand and address. Unfortunately, there is a significant disparity in utilization of mental health (MH) care and VA access as most war Veterans don't seek needed care. New interventions are urgently needed to address disparities in post-deployment MH treatment engagement for war Veterans and to support VA's efforts to provide them with optimal access and care. Online health interventions have been shown to be preferred by OEF/OIF combat Veterans and have the potential to promote access to VA MH care. The investigators' research team has developed a web-based interface (WEB-ED) evolved by feedback from Veterans that screens for common post-deployment MH and readjustment concerns, provides tailored education about positive screens, and facilitates linkage to VA resources. Data from the investigators' prior studies demonstrate WEB-ED can be successfully implemented within VA and activate Veterans to seek needed care. Furthermore, emerging evidence indicates that when patients are educated about their health conditions and treatment alternatives using shared decision-making (SDM), increased treatment participation and adherence, and better health outcomes result. Next steps include: linking Veteran WEB-ED screening results to a VA secure network so that a provider can access the results; and integrating a SDM interface to promote Veteran-Provider partnerships in patient-centered care. This study will improve the investigators' understanding of the most effective methods to reduce barriers to enrollment in VA/MHV and transferring important medical information using My HealtheVet (MHV). Furthermore, it will provide important information regarding how WEB-ED results can enhance the capability of VA providers and transition patient advocates to use Veterans' screening results to triage and engage Veterans in patient-centered MH care and promote VA provider adoption of WEB-ED+ to facilitate patient engagement. Online screening, tailored education, and links to geographically accessible VA resources has been shown to be preferred by Veterans, providing recognition of treatable post-deployment MH concerns, and education that reduces stigma. This study builds upon and augments this prior work with research to understand and evaluate the processes needed to integrate WEB-ED+ into current VHA systems to support efficient care delivery, facilitate patient-centered care, and address unmet need for MH care while also resolving disparities in VA and VA MH care access and engagement for war Veterans. WEB-ED+'s use of shared decision making is a key component for promoting these benefits. WEB-ED+ represents a readily implementable and cost-effective intervention that, with partner collaboration, can be integrated into VA systems through MHV. Findings have important policy implications for several operational partners heavily invested in the improved access and delivery of evidence-based mental health care for war Veterans.

This study will assess the effects of acute low-dose opioid administration on functional neuroimaging measures in healthy individuals

Clomiphene (Clomid) is a drug FDA approved to treat female infertility, however, it is often used by men in an off-label setting to both treat male infertility and in a multitude of sports disciplines to increase performance. Study Objectives: Determine detection windows for clomiphene and its metabolites in urine following a medium-term administration Understand the effect of clomiphene administration on luteinizing hormone (LH), follicle-stimulating hormone (FSH), and serum testosterone (T) concentrations in a longitudinal manner Identify changes in current steroidal module of Athlete Biological Passport

This study will test the effects of the Leadership and Organizational Change for Implementation (LOCI) intervention in facilitating evidence-based practice (EBP) implementation in substance use disorder (SUD) and HIV services settings. LOCI improves implementation leadership and organizational support to develop strategic climate for EBP implementation. Greater efficiency and effectiveness of EBP implementation will improve the public health impact of evidence-based health and allied healthcare innovations and lead to greater effectiveness of SUD and HIV services.

The pilot test of Centervention-ATOD, a customizable suite of online tools specifically designed to support quality implementation and sustainability of any ATOD-EBP within real-world service settings, will evaluate whether the product awards additive benefits in provider implementation proficiency and efficacy, quality of implementation delivery, and EBP (i.e., Free Talk or CHOICE) outcomes compared to traditional implementation methods. Additionally, a cost-effectiveness study will be conducted to assess whether the implementation support strategy (i.e., Centervention-ATOD) is more cost-effective than traditional implementation methods.

The investigators seek to develop and assess the effectiveness of Substance Use Programming for Person-Oriented Recovery and Treatment (SUPPORT), a community-driven recovery-oriented system of care for individuals recently released from prison. SUPPORT is modeled after Indiana Access to Recovery (ATR), a program that operated between October 2007 and December 2014. ATR, a national initiative funded by the Substance Abuse and Mental Health Services Administration (SAMHSA), provided comprehensive, flexible, recovery-oriented services for substance use disorder (SUD). The investigators' local evaluation of this program demonstrated significant improvement in a number of recovery-related outcomes (e.g., substance use, employment, income, involvement in the criminal justice system, and emotional well-being) for clients between intake and discharge. Additionally, qualitative findings from this evaluation demonstrated ATR was well liked among clients and providers. While Indiana ATR did serve a wider range of clients, the investigators have focused SUPPORT on returning inmates because (a) this was the largest group served by the program and (b) there is significant need for evidence-based SUD interventions for this population. The investigators' primary long-term goal is to establish an effective and scalable recovery-oriented system of care for SUD within the reentry population. The investigators will conduct a pilot test comparing SUPPORT clients to clients receiving usual treatment. The investigators will collect quantitative data for both groups at multiple time points to understand the intervention's impact on recovery capital and outcomes and will collect qualitative data from SUPPORT clients to better understand their program and post-discharge experiences.

Opioid use disorder (OUD) is among the costliest and deadliest substance use disorders (SUDs) in the US and world-wide. Opioids were involved in 42,249 deaths in the US in 2016, which were more than deaths due to road accidents and gun violence combined. Opioid overdose deaths were five times higher in 2016 than 1999. Meanwhile, the treatment options for OUD are limited and long-term efficacy is poor. There is a hope that recent advances in understanding of the cognitive neuroscience underlying addictive behavior, like drug craving and its regulatory processes, can bring new opportunities for more effective and personalized treatment options for OUD. Drug craving is the signature aspect of OUD as well as other SUDs which has been associated with continued drug use and relapse. In previous studies, the investigators have shown significant response to drug related cues in both frontoparietal and limbic areas including amygdala and ventral striatum. In a recent pilot study, the investigators showed significant lower connectivity between amygdala and frontoparietal areas, including dorsolateral prefrontal cortex (DLPFC) and inferior parietal cortex (IPC), major nodes of the executive control network (ECN), in patients with OUD compared with healthy controls. The central role of the ECN is to perform top down regulation of subcortical limbic areas during self-control, emotion-regulation, and response- inhibition tasks. These processes are well known to be affected in different psychopathologies including SUDs. There is a growing body of evidence that external frontoparietal synchronization (FPS) with transcranial alternating current stimulation (tACS) can potentially modulate connectivity within ECN and between ECN and limbic areas. This may improve some aspects of executive function and top down regulation. tACS is a low-cost and scalable non-invasive brain stimulation technology without any serious side effects. The procedure involves the transcranial delivery of low levels of alternating current (0.1-2 mAmp) in different frequencies through the skull into the brain with both online and long-term offline effects. This trial is the first combined tACS/fMRI study to examine the acute offline effects of FPS on neural substrates underlying drug induced craving. We hypothesize that FPS amplifies the ECN top-down modulatory role via its connectivity to other cortical-subcortical areas. In this experimental design, the investigators will recruit 60 people with OUD during the early abstinence phase in a residential setting divided into two parallel arms with active and sham FPS tACS. Each subject will undergo resting state and task based (drug cue exposure paradigm) functional MRI pre and post FPS. The investigators will also conduct individual difference analyses to explore the potential predictors for FPS response, including pre-FPS top-down connectivity measures of ECN and other subjective, clinical, behavioral, structural, and functional variables. The results of this study will provide mechanistic neuroscience-based evidence for the efficacy of FPS and will advance the field towards precision addiction medicine.
