723-732AbstractIntervetions are urgently needed to reduce the trajectory of the US opioid overdose epidemic, yet implementation is often hampered by resistance or opposition from key community stakeholders. While businesses are economically and physically impacted by the opioid epidemic, they are rarely engaged in efforts to reduce its impact. The establishment of overdose prevention sites (OPS) is being discussed throughout many US jurisdictions with limited attention to the potential positive role of businesses in that process. We surveyed business owners and employees of businesses located in neighborhoods with concentrated drug markets. The study’s primary aim was to examine their attitudes to locally-placed OPS. An iterative, two-phase sampling strategy was used to identify recruitment zones. In person (December 2019–March 2020) and telephone-based (April–July 2020) surveys were administered to distinct business owners and employees (N = 149). Sixty-five percent of participants supported OPS in their neighborhood and 47% had recently witnessed an overdose in or around their workplace. While 70% had heard of naloxone, and 38% reported having it on the premises. Correlates of supporting an OPS locally included living in the same neighborhood as work (adjusted odds ratio (aOR) 1.99, 95% confidence intervals (CI): 1.30–3.05); having a more positive attitude towards people who use drugs (aOR 1.33, 95% CI: 1.13–1.58); and having recently seen an overdose in/around the workplace (aOR 2.86, 95% CI: 1.11–7.32). Lack of support being an owner (aOR 0.35, 95% CI: 0.15–0.83). These data indicate the extent to which businesses are directly impacted by the opioid epidemic and the power of personal experience in shaping OPS support in advocacy efforts.Agency in the fentanyl era : Exploring the utility of fentanyl test strips in an opaque drug market

84AbstractBackground: In Baltimore, the emergence of fentanyl and its analogues exacerbated an existing heroin crisis and increased uncertainty about drug composition and potency. In an effort to reduce overdoses, harm reduction organizations and health departments across the U.S. began distributing fentanyl test strips, a low barrier, inexpensive drug checking strategy. Studies show that people who use drugs (PWUD) frequently suspect that their drugs contain fentanyl and are interested in using fentanyl test strips to check their drugs; however, some people question their usefulness in regions where fentanyl presence is assumed. Understanding the utility of fentanyl test strips in fentanyl-saturated markets is a priority to best tailor interventions. Methods: In-depth interviews (N = 20) were conducted with individuals who reported recent (past 30 days) opioid use in Baltimore, MD. Results: Fentanyl was viewed as pervasive, dangerous, and difficult to avoid in the local drug supply. This dominant narrative characterized PWUD as disempowered by the heightened unpredictability of the drug market. While several strategies are used to navigate the drug market, respondents wanted more information about their drugs. In this context, fentanyl test strips were used in unique and unexpected ways to empower PWUD to be savvier market consumers, including avoiding fentanyl when there could be negative social or legal consequences, negotiating with dealers, and helping others in their social network navigate the opaque drug market. Conclusion: These findings add nuance and place fentanyl preference and use in the context of the drug market. When fentanyl presence is assumed, people used fentanyl test strips in unexpected ways to gain some control over their drug use. Novel uses for fentanyl test strips strengthen existing strategies used to navigate the drug market and mitigate overdose risk, and highlight their potential to quickly disseminate valuable information about the local drug supply.Alternative use of buprenorphine among people who use opioids in three U.S. Cities

364-370AbstractBackground: Buprenorphine is an effective treatment for opioid use disorder, yet some persons are concerned with its “alternative use” (i.e., any use unintended by the prescriber). There is limited evidence on the factors associated with alternative use of buprenorphine (AUB); in this study, we examined correlates of recent (past 6 months) AUB. Methods: Multivariable logistic regression was used to analyze survey data from a multi-site, cross-sectional study of people who use drugs (PWUD) (N = 334) in Baltimore, Maryland; Boston, Massachusetts; and Providence, Rhode Island. Results: One-fifth (20%) of the sample reported recent AUB. In adjusted analyses, significant negative correlates of AUB were female gender (adjusted odds ratio [aOR] 0.48, 95% confidence intervals [CI] 0.24–0.95), recent emergency room visit (aOR 0.45, 95% CI 0.23–0.89), and recent injection drug use (aOR 0.41, 95% CI 0.19–0.88). Significant positive correlates were alternative use of other prescription opioids (aOR 8.32, 95% CI 4.22–16.38), three or more overdoses in the past year (aOR 3.74, 95% CI 1.53–9.17), recent buprenorphine use as prescribed (aOR 2.50, 95% CI 1.12–5.55), and recent residential rehabilitation treatment (aOR 3.71, 95% CI 1.50–9.16). Conclusions: Structural and behavioral correlates of AUB may help identify PWUD at high risk of overdose with unmet treatment needs.Astrovirus infection and diarrhea in 8 countries

1AbstractBackground and Objectives: Astroviruses are important drivers of viral gastroenteritis but remain understudied in community settings and low- and middle-income countries. We present data from 8 countries with high prevalence of diarrhea and undernutrition to describe astrovirus epidemiology and assess evidence for protective immunity among children 0 to 2 years of age. Methods: We used 25 898 surveillance stools and 7077 diarrheal stools contributed by 2082 children for enteropathogen testing, and longitudinal statistical analysis to describe incidence, risk factors, and protective immunity. Results: Thirty-five percent of children experienced astrovirus infections. Prevalence in diarrheal stools was 5.6%, and severity exceeded all enteropathogens except rotavirus. Incidence of infection and diarrhea were 2.12 and 0.88 episodes per 100 child-months, respectively. Children with astrovirus infection had 2.30 times the odds of experiencing diarrhea after adjustment for covariates (95% confidence interval [CI], 2.01-2.62; P < .001). Undernutrition was a risk factor: odds of infection and diarrhea were reduced by 10% and 13%, respectively, per increase in length-for-age z score (infection: odds ratio, 0.90 [95% CI, 0.85-0.96]; P < .001; diarrhea: odds ratio, 0.87 [95% CI, 0.79-0.96]; P = .006). Some evidence of protective immunity to infection was detected (hazard ratio, 0.84 [95% CI, 0.71-1.00], P = .052), although this was heterogeneous between sites and significant in India and Peru. Conclusions: Astrovirus is an overlooked cause of diarrhea among vulnerable children worldwide. With the evidence presented here, we highlight the need for future research as well as the potential for astrovirus to be a target for vaccine development.Beliefs of US chiefs of police about substance use disorder, fentanyl exposure, overdose response, and use of discretion : results from a national survey

1AbstractBackground: To inform the feasibility and acceptability of evidence-informed police practices related to substance use, addiction, and overdose, we sought to better understand how US police chiefs perceive substance use and related policing practices. Methods: A national sample of randomly selected US police chiefs (N = 276) completed a 37-item survey about substance use and policing. Nine items assessed chiefs’ perceptions of: officers’ discretion in making arrests, effectiveness of overdose responses, risks of fentanyl exposure, de-escalation practices, harmful drugs in their community, and illicitly-obtained buprenorphine. Data were analyzed with descriptive statistics and exploratory ordinal logistic regressions. Results: Most chiefs (72.5%) agreed that arrest for any nonviolent misdemeanor was at the discretion of their officers, and they overwhelmingly (94.9%) trusted their officers to make the right arrest decision. The majority of chiefs (87.7%) felt their officers could effectively respond to an opioid overdose, and 83.7% reported their officers carried naloxone on patrol. Chiefs in the Northeast were significantly less likely to be confident in their officers’ ability to respond to a methamphetamine overdose than chiefs in the West. Most (90.0%) were receptive to implementing methamphetamine de-escalation strategies (i.e., techniques to resolve crises short of force). Almost all chiefs (91.2%) agreed with the inaccurate statement that fentanyl exposure at a drug overdose scene could harm officers. Conclusions: Police chiefs express interest in several types of evidence-based public health approaches to policing. Critically, there is a need to curtail fentanyl misinformation and to improve officer knowledge about medications for treating opioid use disorder.Businesses in high drug use areas as potential sources of naloxone during overdose emergencies

233AbstractIntroduction: Naloxone distribution remains a cornerstone of a public health approach to combating the ongoing opioid overdose crisis. Most distribution programs focus on providing naloxone to individuals who use drugs or those closely associated with them (e.g., family). Utilizing businesses as fixed location sources of naloxone could be a valuable supplemental strategy to preventing fatal overdoses that is underexplored in the literature. Methods: We surveyed business owners and employees (N = 149) located in neighborhoods characterized by high rates of drug use in Baltimore City. Participants reported their interactions with people who use drugs as well as if they had heard of naloxone, if the business had naloxone on the premises, and how many employees were trained to use naloxone. Results: Most participants reported seeing individuals under the influence of drugs (93%), public drug use (80%), and overdose (66%) while at work. 66% of participants had heard of naloxone. Among those who had heard of naloxone, only 39% reported that there was a naloxone kit in the business and 28% of businesses had multiple employees trained to use naloxone. Conclusions: Businesses are underutilized as potential reliable sources of naloxone. While study participants reported high levels of exposure to drug use and overdose in and around their businesses, their ability to intervene was limited. Efforts to train employees to respond to overdoses and to keep naloxone on site are warranted to supplement existing naloxone distribution efforts and can help empower business staff to help prevent overdose mortality in their communities.Confirmatory Factor Analysis and Construct Validity of the Internalized Sex Work Stigma Scale among a Cohort of Cisgender Female Sex Workers in Baltimore, Maryland, United States

713-723AbstractInternalized sex work stigma among cisgender female sex workers (FSW) is produced within contexts of social marginalization and associated with a range of ill-effects, including psychological distress, and lower rates of healthcare-seeking. This study seeks to uncover latent domains of the new Internalized Sex Work Stigma Scale (ISWSS) using data from 367 FSW in Baltimore, Maryland, USA. The sample was 56% white with high substance use (82% smoked crack cocaine, 58% injected any drug). The average ISWSS score was 34.8 (s.d. = 5.8, possible range: 12–48) and internal consistency was high (0.82). Confirmatory factor analysis revealed four subscales: worthlessness, guilt and shame, stigma acceptance, and sex work illegitimacy. Internal consistency of subscales was high (0.69–0.90); the scale also demonstrated construct validity with depression and agency. In bivariate logistic regressions, higher ISWSS, worthlessness, shame and guilt, and acceptance scores predicted higher odds of rushing client negotiations due to police. In unadjusted multinomial regressions, feeling respected by police predicted lower ISWSS, worthlessness, guilt and shame, acceptance, and illegitimacy scores. Identified factors are congruent with existing literature about how FSW manage sex work-specific stigma. Understanding the unique dimensions and impacts of internalized sex work stigma can inform interventions and policy to reduce morbidities experienced by FSW.Cost analysis of a school-based comprehensive malaria program in primary schools in Sikasso region, Mali

1AbstractBackground: The expansion of malaria prevention and control to school-aged children is receiving increasing attention, but there are still limited data on the costs of intervention. This paper analyses the costs of a comprehensive school-based intervention strategy, delivered by teachers, that included participatory malaria educational activities, distribution of long lasting insecticide-treated nets (LLIN), and Intermittent Parasite Clearance in schools (IPCs) in southern Mali. Methods: Costs were collected alongside a randomised controlled trial conducted in 80 primary schools in Sikasso Region in Mali in 2010-2012. Cost data were compiled between November 2011 and March 2012 for the 40 intervention schools (6413 children). A provider perspective was adopted. Using an ingredients approach, costs were classified by cost category and by activity. Total costs and cost per child were estimated for the actual intervention, as well as for a simpler version of the programme more suited for scale-up by the government. Univariate sensitivity analysis was performed. Results: The economic cost of the comprehensive intervention was estimated to $10.38 per child (financial cost $8.41) with malaria education, LLIN distribution and IPCs costing $2.13 (20.5%), $5.53 (53.3%) and $2.72 (26.2%) per child respectively. Human resources were found to be the key cost driver, and training costs were the greatest contributor to overall programme costs. Sensitivity analysis showed that an adapted intervention delivering one LLIN instead of two would lower the economic cost to $8.66 per child; and that excluding LLIN distribution in schools altogether, for example in settings where malaria control already includes universal distribution of LLINs at community-level, would reduce costs to $4.89 per child. Conclusions: A comprehensive school-based control strategy may be a feasible and affordable way to address the burden of malaria among schoolchildren in the Sahel.De Facto Decriminalization for Drug Possession and Sex Work in Baltimore, Maryland

989-999AbstractBackground. Detrimental effects of diarrhea on child growth and survival are well documented, but details of the underlying mechanisms remain poorly understood. Recent evidence demonstrates that perturbations to normal development of the gut microbiota in early life may contribute to growth faltering and susceptibility to related childhood diseases. We assessed associations between diarrhea, gut microbiota configuration, and childhood growth in the Peruvian Amazon. Methods. Growth, diarrhea incidence, illness, pathogen infection, and antibiotic exposure were assessed monthly in a birth cohort of 271 children aged 0-24 months. Gut bacterial diversity and abundances of specific bacterial taxa were quantified by sequencing 16S rRNA genes in fecal samples collected at 6, 12, 18, and 24 months. Linear and generalized linear models were used to determine whether diarrhea was associated with altered microbiota and, in turn, if features of the microbiota were associated with the subsequent risk of diarrhea. Results. Diarrheal frequency, duration, and severity were negatively associated with bacterial diversity and richness (P < .05). Children born stunted (length-for-age z-score [LAZ] ≤ -2) who were also severely stunted (LAZ ≤ -3) at the time of sampling exhibited the greatest degree of diarrhea-associated reductions in bacterial diversity and the slowest recovery of bacterial diversity after episodes of diarrhea. Increased bacterial diversity was predictive of reduced subsequent diarrhea from age 6 to 18 months. Conclusions. Persistent, severe growth faltering may reduce the gut microbiota's resistance and resilience to diarrhea, leading to greater losses of diversity and longer recovery times. This phenotype, in turn, denotes an increased risk of future diarrheal disease and growth faltering.Discordance between Self-reported and Biologically Tested Exposure to Fentanyl among People at Risk of Opioid Overdose

722-724AbstractDrug overdose remains a leading cause of death in the US, and the majority of opioid overdose fatalities involve fentanyl. This study aims to measure the degree of concordance between self-reported and biologically tested exposure to fentanyl. We conducted a cross-sectional analysis using survey and urinalysis data collected between 2019 and 2020 from Anne Arundel County, Maryland. Among urinalysis participants (n =113), 30% reported daily fentanyl use, and among this group, only 54% had a fentanyl-positive result. Cohen Kappa between self-reported and biologically detected fentanyl use was 0.26, indicating minimal agreement between the 2 markers. Limitations to interpreting self-reported and urinalysis data are discussed in this report.Disruptions to naloxone training among lay and occupational responders in Maryland during the emergence of COVID-19: Early impacts, recovery, and lessons learned

100173AbstractBackground Opioid overdose death rates increased during the COVID-19 pandemic. Disruptions in community-based naloxone trainings could have reduced the likelihood of overdose reversal and increased the chances of a fatal overdose. We investigated changes in the number of people trained in naloxone administration and distribution in Maryland before, during, and after COVID-related stay-at-home orders. Methods Data on naloxone training are from the Maryland Department of Health. We used interrupted time series models to estimate changes in average monthly number of people trained: [1] pre-interruption (4/2019???3/2020), [2] 1-month post-interruption (4/2020???5/2020), and [3] 12-month post-interruption (4/2020???3/2021). Trainees were classified as lay (e.g., people who use drugs) or occupational (e.g., law enforcement officers and harm reduction workers) responders. Results There were 101,332 trainees; 54.1% lay, 21.5% occupational, and 23.4% unknown responder status. We observed a decrease in the average monthly number of trainees in the pre-interruption period (-235, pEducation, Income, Wealth, and Discrimination in Black-White Allostatic Load Disparities

American journal of preventive medicineAbstractIntroduction: Allostatic load (AL) is a significant marker of aging, associated with disease and mortality. Research has elucidated the impact of education and income on AL. However, the roles of wealth and discrimination in contributing to AL and shaping AL disparities remain underexplored. This study aimed to investigate the association between wealth and AL, while also examining the independent contributions of education, income, wealth, and everyday discrimination in shaping AL disparities. Methods: Using 2016 data from the nationally representative Health and Retirement Study (N=3,866), this study employed multilinear regression analysis to quantify the association between education and income, wealth (calculated as assets minus debts), and everyday discrimination with AL. Oaxaca-Blinder decomposition analysis was conducted to determine the proportion of AL disparities between Black and White participants attributed to education and income, wealth, and everyday discrimination. Analyses were performed in 2023. Results: Having a college degree or more (b = −0.32; 95% CI: −0.46, −0.17), higher income (b = −0.06; 95% CI: −0.11, −0.01), and greater wealth (b = −0.11; 95% CI: −0.16, −0.07) were linked to reduced AL. Conversely, increased experiences of everyday discrimination were associated with heightened AL (b = 0.07; 95% CI: 0.01, 0.16). Collectively, differences in possessing a college degree or more, wealth, and exposure to discrimination accounted for about 18% of the observed Black-White AL disparities. Conclusions: Education, income, wealth, and experiences of discrimination may independently contribute to AL and partially explain Black-White disparities in AL. There is a need to elucidate the underlying mechanisms governing these relationships, particularly wealth, and extend the research to additional social determinants of racial health disparities.Emerging models of de facto drug policy reforms in the United States

260AbstractBackground: Health and human rights organizations have endorsed drug decriminalization to promote public health-oriented approaches to substance use. In the US, policymakers have begun to pursue this via prosecutorial discretion—or the decision by a prosecutor to decline criminal charges for drug possession in their jurisdiction. This study characterizes drivers of adoption, policy design and implementation processes, and barriers to impact and sustainability of this approach to inform evolving policy efforts promoting the health of people who use drugs (PWUD). Methods: We conducted n=22 key informant interviews with policymakers and national policy experts representing 13 jurisdictions implementing de facto drug policy reforms. Analyses were informed by the Exploration, Preparation, Implementation and Sustainment (EPIS) framework and analyzed using a hybrid inductive-deductive approach. Results: Drivers of policy adoption included racial inequities, perceived failures of criminalization, and desires to prioritize violent crime given resource constraints. Three distinct policy typologies are described with varying conditions for eligibility, linkage to services, and policy transparency and dissemination. Public misinformation, police resistance and political opposition were seen as threats to sustainability. Conclusions: Given evidence that criminalization amplifies drug-related harms, many policymakers are adopting de facto drug policy reforms in the absence of formal legislation. This is the first study to systematically describe relevant implementation processes and emerging policy models. Findings have implications for designing rigorous evaluations on health outcomes and informing sustainable evidence-based policies to promote health and racial equity of PWUD in the US.Epidemiology of drug arrests in the United States : Evidence from the national survey on drug use and health, 2015–2019

185AbstractObjective: Following changes to drug criminalization policies, we re-examine the epidemiology of drug arrests among people who use drugs (PWUD) in the U.S. Methods: Serial cross-sectional data from the National Survey on Drug Use and Health (2015–2019) were utilized. Past-year illicit drug use (excluding cannabis) and drug arrests were described by year, area of residence, drug use characteristics and participant demographics. Adjusted associations between race and drug arrest were estimated using multivariable logistic regression. Results: Past-year illicit drug use remained consistent over time and was highest among non-Hispanic (NH) white respondents. Of those reporting past-year illicit drug use (n = 25,429), prevalence of drug arrests remained stable over time overall and in metro areas while increasing in non-metro areas. Arrests were elevated among NH Black participants and those with lower income, unemployment, housing transience, non-metro area residence, polysubstance use, history of drug injection, substance use dependence and past-year drug selling. Adjusted odds of drug arrest remained significantly higher among NH Black individuals [aOR 1.92, 95% CI 1.30, 2.84]. Conclusion: Despite recent shifts away from punitive drug policies, we detected no reduction in drug arrests nationally and increasing prevalence in non-metro areas. Despite reporting the lowest level of illicit substance use and drug selling, NH Black individuals had significantly increased odds of arrest across years. Findings highlight the need for further examination of policy implementation and policing practices in different settings, with more research focused non-metro areas, to address enduring structural racism in drug enforcement and its consequences for health.Examining the association between psychological resilience and chronic versus discrete stressors among individuals who use opioids in Baltimore, Maryland

Drug and Alcohol ReviewAbstractIntroduction: Psychological resilience has emerged as a key construct of interest in the study of substance use. However, very few studies have examined resilience among individuals who are actively using drugs. Furthermore, many studies of psychological resilience have focused on individual-level factors. This study addresses the call for a more ‘ecological’ approach to the study of resilience by exploring how socio-structural vulnerabilities may shape individuals' assessment of their own ability to cope. Methods: The Peer Harm Reduction of Maryland Outreach Tiered Evaluation study conducted a cross-sectional survey of people who used opioids in Baltimore, Maryland, USA (n = 565). Resilience was measured using the 10-item Connor-Davidson Resilience Scale. We used linear regression to examine the association between resilience and stressors commonly encountered by individuals who use drugs, including both chronic, enduring stressors (e.g., homelessness, food insecurity) and discrete, event-based stressors (e.g., overdose, arrest). Results: We observed a negative relationship between self-reported resilience and chronic stressors. Specifically, individuals who reported experiencing three (β = −4.08; p = 0.002) or four (β = −4.67; p = 0.008) types of chronic stress had significantly lower resilience scores. Additionally, we found that an unmet need for mental health treatment was associated with reduced resilience (β = −1.74; p = 0.040) and greater educational attainment was associated with increased resilience (β = 2.13; p = 0.005). Discussion and Conclusions: Overlapping experiences of socio-structural vulnerability, as well as access to mental health care, may influence how individuals who use drugs evaluate their own resilience. Interventions that seek to promote the resilience of this population should focus on addressing structural drivers of marginalisation and barriers to mental health treatment.Factors associated with daily use of benzodiazepines/tranquilizers and opioids among people who use drugs

American Journal on AddictionsAbstractBackground: Co-use of benzodiazepines and opioids significantly increases fatal overdose risk, yet few studies have examined co-use of these drugs when obtained both with and without a prescription. We examined associations of daily co-use of prescribed benzodiazepines/tranquilizers (BZD/TRQ) and prescribed and nonprescribed opioids among people who use street opioids (PWUO). Methods: PWUO (N = 417) were recruited from Baltimore City and neighboring Anne Arundel County, Maryland, and surveyed on sociodemographic characteristics, structural vulnerabilities, healthcare access and utilization, substance use, and overdose experiences. Multivariable logistic regression was used to identify factors associated with self-reported co-use. Results: Participants were 46 years old on average, and predominantly Black (74%) males (62%). Daily co-use was reported by 22%. In multivariable analyses, odds of co-use were significantly higher among participants who did not have a high school degree/GED (adjusted odds ratio [aOR]: 1.71, 95% confidence interval [CI]: 1.02–2.88), endorsed receiving mental health treatment in the past 6 months (aOR: 2.13, 95% CI: 1.28–3.56), reported daily use of powdered cocaine (aOR: 3.57, 95% CI: 1.98–6.45), and synthetic cannabinoids (aOR: 3.11, 95% CI: 1.40–6.93). Odds of co-use were significantly lower among Black participants compared to white participants (aOR: 0.39, 95% CI: 0.19–0.82). Conclusions and Scientific Significance: Clinicians working with PWUO or who prescribe BZDs or opioids should screen patients who use cocaine or synthetic cannabinoids, have low level of educational attainment, or recently accessed mental health services, as these patients may be at higher risk for daily co-use of BZD/TRQ and opioids, and therefore lethal overdose.Factors associated with receptive injection equipment sharing among people who inject drugs : findings from a multistate study at the start of the COVID-19 pandemic

1AbstractBackground: Receptive injection equipment sharing (i.e., injecting with syringes, cookers, rinse water previously used by another person) plays a central role in the transmission of infectious diseases (e.g., HIV, viral hepatitis) among people who inject drugs. Better understanding these behaviors in the context of COVID-19 may afford insights about potential intervention opportunities in future health crises. Objective: This study examines factors associated with receptive injection equipment sharing among people who inject drugs in the context of COVID-19. Methods: From August 2020 to January 2021, people who inject drugs were recruited from 22 substance use disorder treatment programs and harm reduction service providers in nine states and the District of Columbia to complete a survey that ascertained how the COVID-19 pandemic affected substance use behaviors. We used logistic regression to identify factors associated with people who inject drugs having recently engaged in receptive injection equipment sharing. Results: One in four people who inject drugs in our sample reported having engaged in receptive injection equipment sharing in the past month. Factors associated with greater odds of receptive injection equipment sharing included: having a high school education or equivalent (adjusted odds ratio [aOR] = 2.14, 95% confidence interval [95% CI] 1.24, 3.69), experiencing hunger at least weekly (aOR = 1.89, 95% CI 1.01, 3.56), and number of drugs injected (aOR = 1.15, 95% CI 1.02, 1.30). Older age (aOR = 0.97, 95% CI 0.94, 1.00) and living in a non-metropolitan area (aOR = 0.43, 95% CI 0.18, 1.02) were marginally associated with decreased odds of receptive injection equipment sharing. Conclusions: Receptive injection equipment sharing was relatively common among our sample during the early months of the COVID-19 pandemic. Our findings contribute to existing literature that examines receptive injection equipment sharing by demonstrating that this behavior was associated with factors identified in similar research that occurred before COVID. Eliminating high-risk injection practices among people who inject drugs requires investments in low-threshold and evidence-based services that ensure persons have access to sterile injection equipment.Food access among people who inject drugs in West Virginia

1AbstractBackground: The substance use epidemic in the United States continues to drive high levels of morbidity and mortality, particularly among people who inject drugs (PWID). Poor access to food often co-occurs with drug use and contributes to associated sequelae, such as risks for HIV and diabetes. The objective of this study was to examine factors associated with adequate food access among PWID in a rural Appalachian community. Methods: Cross-sectional surveys were used to collect data among PWID aged 18 and older in Cabell County, West Virginia. Frequency of hunger and sociodemographic, structural and drug use characteristics were measured. Adequate food access was defined as reporting ‘never’ going to bed hungry at night in the past six months. Pearson’s χ2 and t-tests and multivariable logistic regression were used to identify factors associated with food access. Results: Only 71 individuals (17%) reported never going to bed hungry at night in the past six months. Adjusted odds of having adequate food access were higher among PWID who completed high school (aOR 2.94; P = 0.010) and usually used drugs alone (aOR 1.97; P = 0.025), and lower among PWID who were female (aOR 0.51; P = 0.037), experienced homelessness (aOR 0.23, P < 0.001), were recently arrested (aOR 0.50 P = 0.047), and engaged in receptive sharing of injection equipment (aOR 0.52, P = 0.035). Conclusions: We found extremely low food access in a population of PWID in Appalachia who are vulnerable to overdose and infectious disease transmission. Integrated interventions promoting food access are needed to improve the public health and wellbeing of people who inject drugs in Appalachia.Gut microbiota features associated with campylobacter burden and postnatal linear growth deficits in a peruvian birth cohort

1000-1007AbstractBackground. Campylobacter infection is associated with impaired growth of children, even in the absence of symptoms. To examine the underlying mechanisms, we evaluated associations between Campylobacter infection, linear growth, and fecal microbial community features in a prospective birth cohort of 271 children with a high burden of diarrhea and stunting in the Amazonian lowlands of Peru. Methods. Campylobacter was identified using a broadly reactive, genus-specific enzyme-linked immunosorbent assay. 16S rRNAbased analyses were used to identify bacterial taxa in fecal samples at ages 6, 12, 18, and 24 months (N = 928). Associations between infection, growth, and gut microbial community composition were investigated using multiple linear regression adjusting for withinchild correlations, age, and breastfeeding. Indicator species analyses identified taxa specifically associated with Campylobacter burden. Results. Ninety-three percent (251) of children had Campylobacter present in asymptomatic fecal samples during the follow-up period. A 10% increase in the proportion of stools infected was associated with mean reductions of 0.02 length-for-age z scores (LAZ) at 3, 6, and 9 months thereafter (P < .01). We identified 13 bacterial taxa indicative of cumulative Campylobacter burden and 14 taxa significantly associated with high or low burden of enteroaggregative Escherichia coli, norovirus, or Giardia. Conclusions. Campylobacter infection is common in this cohort and associated with changes in microbial community composition. These results support the notion that disruptions to the fecal microbiota may help explain the observed effects of asymptomatic infections on growth in early life.Harm reduction measures employed by people using opioids with suspected fentanyl exposure in Boston, Baltimore, and Providence

1AbstractBackground: Exposure to potent synthetic opioids such as illicitly manufactured fentanyl (IMF) has fueled the escalating overdose crisis in the USA, particularly in the east coast. Drug checking services, which allow people who use drugs (PWUD) to learn about the contents of their drugs, remain limited and even criminalized in many states. Further, there is a persistent belief that PWUD are not willing or able to change their behaviors despite being aware of their potential exposure to fentanyl through drug use. Methods: We conducted a multi-site cross-sectional study among PWUD to assess what behaviors, if any, were employed in the case of suspected fentanyl exposure, and the correlates of engaging in harm reduction behaviors (HRB). PWUD (N = 334) were recruited in Boston (n = 80), Providence (n = 79), and in Baltimore (n = 175). At the time of the survey, no legal drug checking services were available in these cities. Results: The majority of PWUD (84%) expressed concern about fentanyl. Among those who suspected fentanyl exposure prior to using their drugs (n = 196), 39% reported employing HRB including using less of the drug (12%) or abstaining altogether (10%), using more slowly (5%), and doing a tester shot (5%). In adjusted logistic regression models, the odds (aOR) of practicing HRB after suspecting fentanyl exposure were increased among PWUD who were non-White (aOR 2.1; p = 0.004) and older (aOR 1.52 per decade of age; p < 0.001). Daily injection (aOR 0.50; p < 0.001), using drugs in public (aOR 0.58; p = 0.001), using drugs alone (aOR 0.68; p < 0.001), and experiencing multiple recent overdoses (aOR 0.55; p < 0.001) were associated with decreased odds of practicing HRB. Conclusions: These data illustrate that PWUD employ a number of practices to reduce overdose risk in a context of unknown drug purity and content. Results may also guide efforts to identify early adopters of drug checking services and engage them in peer-outreach to target the most socially and structurally vulnerable PWUD, who are not reporting behavior change, with harm reduction messaging.Harms associated with injecting in public spaces : a global systematic review and meta-analysis

140AbstractBackground: Despite increasing backlash against harm reduction efforts and the need to understand the risk environments encountered by people who inject drugs (PWID), a quantitative systematic review on public injecting and associated health and drug-related outcomes is lacking. We aimed to summarize the global evidence on the prevalence and harms associated with injecting in public spaces. Methods: We searched MEDLINE, Embase, PsycINFO, CINAHL, Scopus, Global Health, and Web of Science from inception to March 21, 2024. We pooled data from included studies using random-effects meta-analyses to quantify the associations between recent (i.e., current or within the last year) public injecting and associated outcomes. Public injecting was defined as injecting in public or semi-public spaces, including streets, parks, and abandoned buildings. Risk of bias was assessed using the Joanna Briggs Institute's critical appraisal tool. Results: Of the 6144 initial records, 84 studies were eligible for inclusion. The pooled prevalence of recent public injecting was 48.85 % (95 % confidence intervals [CI] 43.87, 53.85). Public injecting was associated with increased odds of recent non-fatal overdose (odds ratio [OR] 2.51, 95 % CI 2.01, 3.13), HCV infection (OR 1.55, 95 % CI 1.18, 2.02), recent needle/syringe sharing (OR 2.41, 95 % CI 1.97, 2.94), recent sex work (OR 1.75, 95 % CI 1.03, 2.97), recent incarceration (OR 2.10, 95 % CI 1.78, 2.47), and recent unstable housing/homelessness (OR 4.23, 95 % CI 3.17, 5.65). Public injecting showed a statistically non-significant association with HIV infection (OR 1.41, 95 % CI 0.80, 2.46). Public injecting was also associated with a higher willingness to use supervised injection facilities (OR 2.66, 95 % CI 1.86, 3.80). Conclusion: Public injecting is prevalent among PWID and associated with various adverse drug- and health-related outcomes, highlighting the need for increased access to safe injection spaces. Findings support developing interventions to reduce harms from public injecting, such as addressing structural risks from law enforcement, expanding naloxone programs, and establishing overdose prevention centers. Housing interventions, in particular, could serve as an effective upstream strategy to reduce public injecting and related harms.High willingness to use overdose prevention sites among female sex workers in Baltimore, Maryland

212AbstractBackground: Overdose Prevention Sites (OPS) operate worldwide as spaces where people can consume previously purchased drugs under supervision, and are linked to reductions in HIV/HCV transmission and fatal overdoses. As the United States weighs their merits and legality, research is needed to estimate acceptability and use among populations at high risk for overdose. We examine willingness to use OPS among street-based female sex workers (FSW) with prevalent drug use and associated morbidities. Methods: We describe self-reported willingness, barriers and conditions around use of a hypothetical OPS among 141 FSW engaged in active drug use in Baltimore City, and describe trends using Pearson's χ2 and Fisher's exact tests. Results: Most women had history of overdose (55 %) and were likely to use OPS (77 %). Willingness was higher among women who: were sexual minorities (97 %;P=0.002),experienced homelessness (82 %;P=0.019), injected drugs (82 %;P=0.013), shared syringes (82 %;P=0.007), experienced sexual violence (92 %;P=0.045) or reported heroin use (83 %;P=0.039) in the past 3 months. Common anticipated barriers included transportation (45 %) and fear of arrest (41 %). Conclusions: This study highlights a population of uniquely high-risk women who would benefit from an OPS integrated with other services. Conditions and barriers discussed are informative for planning and implementation.High willingness to use overdose prevention sites among suburban people who use drugs who do not inject

1AbstractIntroduction: Overdose prevention sites (OPS) are evidence-based interventions to improve public health, yet implementation has been limited in the USA due to a variety of legal impediments. Studies in various US settings have shown a high willingness to use OPS among urban and rural people who inject drugs, but data among people who use drugs (PWUD) via non-injection routes of administration in suburban areas are lacking. Methods: We utilized cross-sectional data from a sample of suburban PWUD who have not injected drugs in the past 3 months (N = 126) in Anne Arundel County, Maryland. We assessed PWUDs’ likelihood of using a hypothetical OPS and perceived potential barriers to accessing OPS. We tested for associations between sociodemographic characteristics, drug use, service access, and overdose experiences with willingness to utilize OPS. Findings: Participants’ median age was 42, and the majority were men (67%) and non-Hispanic Black (79%). Sixty-six percent reported willingness to use an OPS. Concerns about confidentiality (29%), arrest (20%), and transportation costs (22%) were the most anticipated barriers to using OPS. Men (75% vs 55%, p = 0.015), participants who used heroin (53% vs 32%, p = 0.017), and participants who used multiple overdose prevention behaviors (e.g., using fentanyl test strips) (36% vs 19%, p = 0.006) were more likely to report willingness to use OPS. Conclusion: Most suburban non-injecting PWUD in the sample were willing to use an OPS. OPS implementation strategies in suburban settings should be tailored to reach PWUD via non-injection routes of administration while meeting the unique needs of suburban contexts.
