“Once I started going… I had this central wheel hub”
BACKGROUND: The United States' first state-sanctioned overdose prevention center (OPC) opened in Rhode Island in January 2025. In addition to OPC services, the site offers co-located basic needs services, case management, healthcare, and substance use treatment. We aimed to understand clients' initial engagement with the OPC as well as their consequent service patterns. METHODS: Between May and August 2025, semi-structured interviews were conduct…
The Mediating Role of Alcohol Use Between Adverse Childhood Experiences and Delinquency Among Youth in the Legal System
Rates of alcohol use and exposure to adverse childhood experiences (ACEs) are elevated among youth in the legal system (YILS) compared to their non-legally involved peers. Exposure to ACEs has been associated with later alcohol use and delinquency, and YILS often engage in delinquent behavior while under the influence of alcohol. The associations between ACEs, alcohol use, and delinquency among YILS are complex and multidirectional; research has …
Fentanyl test strip use and homelessness among people who use drugs in Rhode Island
We found that housing status was not independently and longitudinally associated with FTS use; however, people who used crystal methamphetamine were more than twice as likely to have used FTS in the past month. Future research exploring how differential housing situations may affect uptake of harm reduction services is needed to prevent fentanyl overdose

Risk and protective factors associated with posttraumatic stress disorder among layperson responders to opioid overdose incidents
Responding to opioid overdoses is traumatizing for many and results in a considerable burden of PTSD among layperson responders. As such, we call for trauma-informed interventions that cater to the unique experiences of layperson opioid overdose responders. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
Pain, Substance Use Disorders, Mental Health, and Buprenorphine Treatment among Patients With and Without HIV
Treatment of opioid use disorder (OUD) with buprenorphine improves outcomes and mortality among people with HIV (PWH). However, engagement is low and is influenced by comorbidities. We examined the impact of patterns of co-occurring pain, substance use disorders (SUDs), and mental health diagnoses on buprenorphine initiation and retention in PWH. The Veterans Aging Cohort Study contained 7,875 patients (2,702 PWH and 5,173 without HIV) with new O…

Early Identification of Suicide Risk Factors Among Justice-Involved Youth
Suicidal thoughts and behaviors among juvenile justice populations are elevated. However, the characteristics of justice-involved youth who consider and attempt suicide are not well understood. This study examined suicidal ideation and attempt with first-time, preadjudicated diverted youth, and the relationship with commonly associated risk factors. The sample included 135 youth (50% male, M age = 14.48) that provided complete responses to self-r…
Sociodemographic and clinical correlates of gabapentin receipt with and without opioids among a national cohort of patients with HIV
Gabapentin is commonly prescribed for chronic pain, including to patients with HIV (PWH). There is growing concern regarding gabapentin's potential for harm, particularly in combination with opioids. Among PWH, we examined factors associated with higher doses of gabapentin receipt and determined if receipt varied by opioid use. We examined data from the Veterans Aging Cohort Study, a national prospective cohort including PWH, from 2002 through 20…
Cannabis use, pain interference, and prescription opioid receipt among persons with HIV
Concomitant with expanded legalization, cannabis is increasingly used to treat chronic pain among persons with HIV (PWH), despite equivocal benefit in research limited by small sample sizes and short duration of follow-up. To address these limitations, among a sample of PWH with pain interference enrolled in the Veterans Aging Cohort Study, we performed a target trial emulation study to compare the impact of four cannabis use strategies on pain i…

Contextualizing Complexity
Development of a Statewide, Publicly Accessible Drug Overdose Surveillance and Information System
In response to Rhode Island’s overdose epidemic, we developed a collaborative, statewide online “dashboard” to provide the public with timely overdose surveillance data. The Web site— www.PreventOverdoseRI.org (PORI)—offers user-friendly data visualizations, plain language education, and interactive resource maps. Development of the site has improved overdose data sharing and transparency in Rhode Island. Preliminary results suggest a successful …
The contextual determinants of sexually transmissible infections among street‐involved youth in North America
Young people living on the urban street are at a significantly increased risk of HIV and other sexually transmitted infections (STIs). Much research examining the epidemiological basis for their heightened susceptibility has concentrated on the individual behaviours and characteristics associated with acquiring these infections. However, contextual factors, including the social, structural and environmental forces that influence sexual risk behav…
Structural factors associated with an increased risk of HIV and sexually transmitted infection transmission among street-involved youth
Although limited by its cross-sectional design, our study found several structural factors amenable to policy-level interventions independently associated with sexual risk behaviours. These findings imply that the criminalization and displacement of street-involved youth may increase the likelihood that youth will engage in sexual risk behaviours and exacerbate the negative impact of resultant health outcomes. Moreover, our findings indicate that…
Injection drug use among street-involved youth in a Canadian setting
These findings highlight an alarmingly high prevalence of injection drug use among street-involved youth and demonstrate its association with an array of risks and harms, including sex work involvement, overdose, and HCV infection. These findings point to the need for a broad set of policies and interventions to prevent the initiation of injection drug use and address the risks faced by street-involved youth who are actively injecting

Difficulty Accessing Syringes Mediates the Relationship Between Methamphetamine Use and Syringe Sharing Among Young Injection Drug Users
Injection drug users (IDU) who use methamphetamine (MA) are at an increased risk of HIV infection due to engagement in injection-related risk behavior including syringe sharing. In this cohort study of young IDU aged 18-30, we investigated the relationship between injection MA use and syringe sharing, and whether difficulty accessing sterile syringes mediated this association. Behavioral questionnaires were completed by 384 IDU in Vancouver, Cana…
Reduction in overdose mortality after the opening of North America's first medically supervised safer injecting facility
Pathways to HIV risk and vulnerability among lesbian, gay, bisexual, and transgendered methamphetamine users
Methamphetamine use was more prevalent among sexual minority males and females and was associated with different sets of HIV risks and vulnerabilities. Our findings suggest that interventions addressing MA-related harms may need to be informed by more nuanced understandings of the intersection between drug use patterns, social and structural HIV vulnerabilities, and gender/sexual identities. In particular, MA-focused prevention and treatment prog…

Longer duration of homelessness is associated with a lower likelihood of non-detectable plasma HIV-1 RNA viral load among people who use illicit drugs in a Canadian setting
Homelessness is common among people who use drugs (PWUD) and, for those living with HIV/AIDS, an important contributor to sub-optimal HIV treatment outcomes. This study aims to investigate the relationship between the duration of homelessness and the likelihood of plasma HIV-1 RNA viral load (VL) non-detectability among a cohort of HIV-positive PWUD. We used data from the ACCESS study, a long-running prospective cohort study of HIV-positive PWUD …
Protocol of the impact of alternative social assistance disbursement on drug-related harm (Tasa) study
NCT02457949 Registered 13 May 2015
Condom use and incarceration among STI clinic attendees in the Deep South
This study found a strong, independent relationship between condom use and multiple, long-term incarceration events among patients in an urban STI clinic in the Deep South. The results suggest that duration of incarceration and multiple incarcerations have significant effects on sexual risk behaviors, underscoring the deleterious impact of long prison or jail sentences on population health. Our findings also suggest that correctional health care …

Effectiveness of peer-led interventions to increase HIV testing among men who have sex with men
The risk of HIV transmission at each step of the HIV care continuum among people who inject drugs
Among PWID in NYC, more than half (53%) of transmissions were from those who were unaware of their infection status and more than 36% were due to PWID who knew their status, but were not on treatment. Our results indicate the importance of early diagnosis and interventions to engage diagnosed PWID on treatment to further suppress population-level HIV transmission. Future HIV prevention research should focus on the elimination of identified and po…
