Anti-HIV Agents - administration & dosage
2025
Although people who inject drugs (PWID) are at high risk of acquiring HIV, knowledge and uptake of pre-exposure prophylaxis (PrEP) for HIV prevention among this population remain low due to numerous psychosocial and structural barriers. Multiple implementation strategies have been proposed to address this gap, notably providing long-acting injectable (LAI) formulations of PrEP and offering PrEP at syringe services programs (SSPs). This qualitative study explores the acceptability and feasibility of offering LAI-PrEP for PWID at risk for HIV at Florida’s first legal SSP. In-depth semi-structured interviews were conducted with PWID (
n
= 25) and healthcare providers (
n
= 5), and transcripts were analyzed using iterative thematic analysis. The provision of LAI-PrEP at the SSP was overwhelmingly acceptable to both PWID and providers, and specific advantages and disadvantages of LAI-PrEP compared to oral PrEP among this population were elucidated. Likewise, PWID and providers identified facilitators and barriers to offering LAI-PrEP at the SSP and proposed recommendations for implementation. Overall, this study adds to the growing evidence that provision of LAI-PrEP at SSPs is acceptable and feasible and holds promise in expanding access to and uptake of HIV prevention services among PWID.

Perspectives on hepatitis A and B screening and immunization at a syringe services program: a mixed-methods study
2026
Background
People who inject drugs (PWID) are at increased risk for viral hepatitis, yet hepatitis A virus (HAV) and hepatitis B virus (HBV) screening and immunization rates remain low. Although offering HAV and HBV services at syringe services programs (SSPs) is effective, few U.S. SSPs currently offer them. Limited qualitative research exists on the advantages and optimization of these services at SSPs. This study explored PWID and SSP staff perspectives regarding barriers to HAV and HBV prevention and care services in traditional healthcare, facilitators for SSP-based provision, and opportunities to improve service delivery.
Methods
This study was conducted at an SSP in Miami, Florida serving over 2500 PWID annually. Quantitative data on vaccine administration from August 2023 to May 2025 were abstracted from the SSP database. Prior to implementation, in May 2022, we conducted in-depth interviews with 15 PWID and 11 SSP staff. Transcripts were analyzed using codebook thematic analysis in Dedoose.
Results
From August 2023 to May 2025, the SSP administered 114 HAV and 176 HBV vaccine doses. Qualitative interviews from May 2022 revealed several key findings. Barriers included limited knowledge, stigma and discrimination, resource and transportation challenges, navigation difficulties, and limited prioritization. Facilitators for SSP-based services included the benefits of co-located, on-demand care, and non-stigmatizing and supportive environment. Opportunities for improvement included offering incentives, expanding outreach, and increasing communication.
Conclusion
PWID face significant barriers to HAV and HBV services in traditional healthcare, including stigma, logistical challenges, and limited awareness of viral hepatitis. Integrating these services into SSPs enhanced accessibility and uptake by leveraging trust, convenience, and harm reduction principles.

Improving access to HIV care among people who inject drugs through tele-harm reduction: a qualitative analysis of perceived discrimination and stigma
2024
Background
Tele-harm reduction (THR) is a telehealth-enhanced, peer-led, harm reduction intervention delivered within a trusted syringe services program (SSP) venue. The primary goal of THR is to facilitate linkage to care and rapid, enduring virologic suppression among people who inject drugs (PWID) with HIV. An SSP in Miami, Florida, developed THR to circumvent pervasive stigma within the traditional healthcare system.
Methods
During intervention development, we conducted in-depth interviews with PWID with HIV (
n
= 25) to identify barriers and facilitators to care via THR. We employed a general inductive approach to transcripts guided by iterative readings of the raw data to derive the concepts, themes, and interpretations of the THR intervention.
Results
Of the 25 PWID interviewed, 15 were in HIV care and adherent to medication; 4 were in HIV care but non-adherent; and 6 were not in care. Themes that emerged from the qualitative analysis included the trust and confidence PWID have with SSP clinicians as opposed to professionals within the traditional healthcare system. Several barriers to treatment were reported among PWID, including perceived and actual discrimination by friends and family, negative internalized behaviors, denial of HIV status, and fear of engaging in care. Facilitators to HIV care included empathy and respect by SSP staff, flexibility of telehealth location, and an overall destigmatizing approach.
Conclusion
PWID identified barriers and facilitators to receipt of HIV care through the THR intervention. Interviews helped inform THR intervention development, centered on PWID in the destigmatizing environment of an SSP.

2023
Background
The resurgence of HIV outbreaks and rising prevalence among people who inject drugs (PWID) remain exigent obstacles to Ending the HIV Epidemic in the USA. Adapting a low threshold, comprehensive treatment model for PWID with HIV can leverage syringe services programs (SSPs) to increase availability and accessibility of antiretrovirals (ART), medications for opioid use disorder (MOUD), and hepatitis C cure. We developed
Tele-Harm Reduction
, a telehealth-enhanced, harm reduction intervention delivered within an SSP venue.
Methods
The T-SHARP trial is an open-label, multi-site, randomized controlled superiority trial with two parallel treatment arms. Participants (
n
=240) recruited from SSPs in Miami, Ft. Lauderdale, and Tampa, Florida, who are PWID with uncontrolled HIV (i.e., HIV RNA>200) will be randomized to
Tele-Harm Reduction
or off-site linkage to HIV care. The primary objective is to compare the efficacy of
Tele-Harm Reduction
for initiation of ART at SSPs vs. off-site linkage to an HIV clinic with respect to viral suppression across follow-up (suppression at 3, 6, and 12 months post randomization). Participants with HIV RNA<200 copies/ml will be considered virally suppressed. The primary trial outcome is time-averaged HIV viral suppression (HIV RNA <200 copies/ml) over 3-, 6-, and 12-month follow-up. Secondary outcomes include initiation of MOUD measured by urine drug screen and HCV cure, defined as achieving 12-week sustained virologic response (negative HCV RNA at 12 weeks post treatment completion). A cost-effectiveness analysis will be performed.
Discussion
The T-SHARP Trial will be the first to our knowledge to test the efficacy of an innovative telehealth intervention with PWID with uncontrolled HIV delivered via an SSP to support HIV viral suppression.
Tele-Harm Reduction
is further facilitated by a peer to support adherence and bridge the digital divide. This innovative, flipped healthcare model sets aside the traditional healthcare system, reduces multi-level barriers to care, and meets PWID where they are. The T-SHARP trial is a pragmatic clinical trial that seeks to transform the way that PWID access HIV care and improve HIV clinical outcomes.

Changes in spirituality partly explain health-related quality of life outcomes after Mindfulness-Based Stress Reduction
2011
Mindfulness-Based Stress Reduction is a secular behavioral medicine program that has roots in meditative spiritual practices. Thus, spirituality may partly explain Mindfulness-Based Stress Reduction outcomes. Participants (
N
= 279;
M
(SD) age = 45(12); 75% women) completed an online survey before and after an 8-week Mindfulness-Based Stress Reduction program. Structural equation modeling was used to test the hypothesis that, following Mindfulness-Based Stress Reduction, the relationship between enhanced mindfulness and improved health-related quality of life is mediated by increased daily spiritual experiences. Changes in both spirituality and mindfulness were significantly related to improvement in mental health. Although the initial mediation hypothesis was not supported, an alternate model suggested that enhanced mindfulness partly mediated the association between increased daily spiritual experiences and improved mental health-related quality of life (indirect effect: β = 0.07,
P
= 0.017). Effects on physical health-related quality of life were not significant. Findings suggest a novel mechanism by which increased daily spiritual experiences following Mindfulness-Based Stress Reduction may partially explain improved mental health as a function of greater mindfulness.

Abstract
Background
To address the infectious disease (ID) and substance use disorder (SUD) syndemic, we developed an integrated ID/SUD clinical team rooted in harm reduction at a county hospital in Miami, Florida. The Severe Injection-Related Infection (SIRI) team treats people who inject drugs (PWID) and provides medical care, SUD treatment, and patient navigation during hospitalization and after hospital discharge. We assessed the impact of the SIRI team on ID and SUD treatment and healthcare utilization outcomes.
Methods
We prospectively collected data on patients seen by the SIRI team. A diagnostic code algorithm confirmed by chart review was used to identify a historical control group of patients with SIRI hospitalizations in the year preceding implementation of the SIRI team. The primary outcome was death or readmission within 90 days post–hospital discharge. Secondary outcomes included initiation of medications for opioid use disorder (MOUD) and antibiotic course completion.
Results
There were 129 patients included in the study: 59 in the SIRI team intervention and 70 in the pre-SIRI team control group. SIRI team patients had a 45% risk reduction (aRR, 0.55 [95% confidence interval CI, .32–.95]; 24% vs 44%) of being readmitted in 90 days or dying compared to pre-SIRI historical controls. SIRI team patients were more likely to initiate MOUD in the hospital (93% vs 33%, P < .01), complete antibiotic treatment (90% vs 60%, P < .01), and less likely to have patient-directed discharge (17% vs 37%, P = .02).
Conclusions
An integrated ID/SUD team was associated with improvements in healthcare utilization, MOUD initiation, and antibiotic completion for PWID with infections.
An integrated infectious disease/substance use disorder (SUD) team to treat injection-related bacterial and fungal infections was associated with a 45% decrease in readmission or death 90 days postdischarge. Additional benefits were demonstrated in antibiotic completion, SUD treatment, and patient-directed discharges.

Introduction
A recent surge in HIV outbreaks, driven by the opioid and stimulant use crises, has destabilized our progress toward targets set forth by
Ending the HIV Epidemic: A Plan for America
for the high-priority community of people who inject drugs (PWID), particularly Black PWID.
Methods
In order to ascertain the acceptability and feasibility of using a mobile syringe services program (SSP) for comprehensive HIV prevention via PrEP and medications for opioid use disorder (MOUD), our mixed methods approach included a quantitative assessment and semi-structured qualitative interviews with Black PWID (
n
= 30) in Miami-Dade County who were actively engaged in mobile syringe services.
Results
Participants felt that delivery of MOUD and PrEP at a mobile SSP would be both feasible and acceptable, helping to address transportation, cost, and stigma barriers common within traditional healthcare settings. Participants preferred staff who are compassionate and nonjudgmental and have lived experience.
Conclusions
A mobile harm reduction setting could be an effective venue for delivering comprehensive HIV prevention services to Black PWID, a community that experiences significant barriers to care via marginalization and racism in a fragmented healthcare system.

Background
People who inject drugs (PWID) remain a high priority population under the federal Ending the HIV Epidemic initiative with 11% of new HIV infections attributable to injection drug use. There is a critical need for innovative, efficacious, scalable, and community-driven models of healthcare in non-stigmatizing settings for PWID. We seek to test a
Comprehensive-TeleHarm Reduction (C-THR)
intervention for HIV prevention services delivered via a syringe services program (SSP).
Methods
The CHARIOT trial is a hybrid type I effectiveness-implementation study using a parallel two-arm randomized controlled trial design. Participants (i.e., PWID; n = 350) will be recruited from a syringe services program (SSP) in Miami, Florida. Participants will be randomized to receive either
C-THR
or non-SSP clinic referral and patient navigation. The objectives are: (1) to determine if the
C-THR
intervention increases engagement in HIV prevention (i.e., HIV pre-exposure prophylaxis; PrEP or medications for opioid use disorder; MOUD) compared to non-SSP clinic referral and patient navigation, (2) to examine the long-term effectiveness and cost-effectiveness of the
C-THR
intervention, and (3) to assess the barriers and facilitators to implementation and sustainment of the
C-THR
intervention. The co-primary outcomes are PrEP or MOUD engagement across follow-up at 3, 6, 9 and 12 months. For PrEP, engagement is confirmed by tenofovir on dried blood spot or cabotegravir injection within the previous 8 weeks. For MOUD, engagement is defined as screening positive for norbuprenorphine or methadone on urine drug screen; or naltrexone or buprenorphine injection within the previous 4 weeks. Secondary outcomes include PrEP adherence, engagement in HCV treatment and sustained virologic response, and treatment of sexually transmitted infections. The short and long term cost-effectiveness analyses and mixed-methods implementation evaluation will provide compelling data on the sustainability and possible impact of
C-THR
on comprehensive HIV prevention delivered via SSPs.
Discussion
The CHARIOT trial will be the first to our knowledge to test the efficacy of an innovative, peer-led telehealth intervention with PWID at risk for HIV delivered via an SSP. This innovative healthcare model seeks to transform the way PWID access care by bypassing the traditional healthcare system, reducing multi-level barriers to care, and meeting PWID where they are.

Mindfulness Meditation Targets Transdiagnostic Symptoms Implicated in Stress-Related Disorders: Understanding Relationships between Changes in Mindfulness, Sleep Quality, and Physical Symptoms
2018
Mindfulness-Based Stress Reduction (MBSR) is an 8-week meditation program known to improve anxiety, depression, and psychological well-being. Other health-related effects, such as sleep quality, are less well established, as are the psychological processes associated with therapeutic change. This prospective, observational study (n=213) aimed to determine whether perseverative cognition, indicated by rumination and intrusive thoughts, and emotion regulation, measured by avoidance, thought suppression, emotion suppression, and cognitive reappraisal, partly accounted for the hypothesized relationship between changes in mindfulness and two health-related outcomes: sleep quality and stress-related physical symptoms. As expected, increased mindfulness following the MBSR program was directly correlated with decreased sleep disturbance (r=-0.21, p=0.004) and decreased stress-related physical symptoms (r=-0.38, p<0.001). Partial correlations revealed that pre-post changes in rumination, unwanted intrusive thoughts, thought suppression, experiential avoidance, emotion suppression, and cognitive reappraisal each uniquely accounted for up to 32% of the correlation between the change in mindfulness and change in sleep disturbance and up to 30% of the correlation between the change in mindfulness and change in stress-related physical symptoms. Results suggest that the stress-reducing effects of MBSR are due, in part, to improvements in perseverative cognition and emotion regulation, two “transdiagnostic” mental processes that cut across stress-related disorders.

Introduction
Analyses of cerebrospinal fluid (CSF) metabolites in large, healthy samples have been limited and potential demographic moderators of brain metabolism are largely unknown.
Objective
Our objective in this study was to examine sex and race differences in 33 CSF metabolites within a sample of 129 healthy individuals (37 African American women, 29 white women, 38 African American men, and 25 white men).
Methods
CSF metabolites were measured with a targeted electrochemistry-based metabolomics platform. Sex and race differences were quantified with both univariate and multivariate analyses. Type I error was controlled for by using a Bonferroni adjustment (0.05/33 = .0015).
Results
Multivariate Canonical Variate Analysis (CVA) of the 33 metabolites showed correct classification of sex at an average rate of 80.6% and correct classification of race at an average rate of 88.4%. Univariate analyses revealed that men had significantly higher concentrations of cysteine (
p
< 0.0001), uric acid (
p
< 0.0001), and N-acetylserotonin (p = 0.049), while women had significantly higher concentrations of 5-hydroxyindoleacetic acid (5-HIAA) (
p
= 0.001). African American participants had significantly higher concentrations of 3-hydroxykynurenine (
p
= 0.018), while white participants had significantly higher concentrations of kynurenine (
p
< 0.0001), indoleacetic acid (
p
< 0.0001), xanthine (
p
= 0.001), alpha-tocopherol (
p
= 0.007), cysteine (
p
= 0.029), melatonin (
p
= 0.036), and 7-methylxanthine (
p
= 0.037). After the Bonferroni adjustment, the effects for cysteine, uric acid, and 5-HIAA were still significant from the analysis of sex differences and kynurenine and indoleacetic acid were still significant from the analysis of race differences.
Conclusion
Several of the metabolites assayed in this study have been associated with mental health disorders and neurological diseases. Our data provide some novel information regarding normal variations by sex and race in CSF metabolite levels within the tryptophan, tyrosine and purine pathways, which may help to enhance our understanding of mechanisms underlying sex and race differences and potentially prove useful in the future treatment of disease.
