Dr. Danielle Ompad is an epidemiologist whose work is focused in the areas of urban health, HIV, illicit drug use, and adult access to vaccines. With respect to illicit drug use, her work has spanned the entire natural history of addiction – from initiation to cessation, with particular attention paid to risk for infectious diseases such as HIV, hepatitis B and C, and STIs. She has primarily worked with people who use heroin, crack, cocaine, and/or club drugs.
In New York City, she has been examining heroin cessation among current, former, and relapsed heroin users. Working with Alliance for Public Health and the Ukrainian Institute on Public Health Policy, she analyzes harm reduction service utilization among people who inject drugs, in order to optimize service delivery in Ukraine. Since 2013, she has served as faculty for the Fogarty-funded New York State International Training and Research Program with the goal of building research capacity in Ukraine.
Dr. Ompad’s National Institute of Allergy and Infectious Diseases-funded study aims to determine if herpes simplex 1 and 2 infections explain racial disparities in HIV incidence among a cohort of young gay, bisexual, and other men who have sex with men (YMSM). In addition, Dr. Ompad and colleagues are assessing HPV infection prevalence, persistence, and clearance among this same cohort.

1AbstractThe Indian state of Odisha has a longstanding battle with forest malaria. Many remote and rural villages have poor access to health care, a problem that is exacerbated during the rainy season when malaria transmission is at its peak. Approximately 62% of the rural population consists of tribal groups who are among the communities most negatively impacted by malaria. To address the persistently high rates of malaria in these remote regions, the Odisha State Malaria Control Program introduced ‘malaria camps’ in 2017 where teams of health workers visit villages to educate the population, enhance vector control methods, and perform village-wide screening and treatment. Malaria rates declined statewide, particularly in forested areas, following the introduction of the malaria camps, but the impact of the intervention is yet to be externally evaluated. This study protocol describes a cluster-assigned quasi-experimental stepped-wedge study with a pretest-posttest control group design that evaluates if malaria camps reduce the prevalence of malaria, compared to control villages which receive the usual malaria control interventions (e.g. IRS, ITNs), as detected by PCR.The effectiveness of malaria camps as part of the malaria control program in Odisha, India

22998AbstractDurgama Anchalare Malaria Nirakaran (DAMaN) is a multi-component malaria intervention for hard-to-reach villages in Odisha, India. The main component, malaria camps (MCs), consists of mass screening, treatment, education, and intensified vector control. We evaluated MC effectiveness using a quasi-experimental cluster-assigned stepped-wedge study with a pretest-posttest control group in 15 villages: six immediate (Arm A), six delayed (Arm B), and three previous interventions (Arm C). The primary outcome was PCR + Plasmodium infection prevalence. The time (i.e., baseline vs. follow-up 3) x study arm interaction term shows that there were statistically significant lower odds of PCR + Plasmodium infection in Arm A (AOR = 0.36, 95% CI = 0.17, 0.74) but not Arm C as compared to Arm B at the third follow-up. The cost per person ranged between US$3-8, the cost per tested US$4-9, and the cost per treated US$82-1,614, per camp round. These results suggest that the DAMaN intervention is a promising and financially feasible approach for malaria control.The effectiveness of malaria camps as part of the malaria control program in Odisha, India

1117-1124AbstractThis article discusses ways in which randomized controlled trials do not accurately measure the impact of HIV behavioral interventions. This is because: 1. Such trials measure the wrong outcomes. Behavior change may have little to do with changes in HIV incidence since behavior change in events between HIV-concordant people have no impact on incidence. Even more important, the comparison of HIV incidence rates between study arms of individual-level RCTs does not measure the true outcome of interest-whether or not the intervention reduces HIV transmission at the community level. This is because this comparison cannot measure the extent to which the intervention stops transmission by HIV-infected people in the study to those outside it. (And this is made even worse if HIV-infected are excluded from the evaluation of the intervention.) 2. There are potential harms implicit in most cognitively oriented behavioral interventions that are not measured in current practice and may not be measurable using RCTs. Intervention trials often reinforce norms and values of individual self-protection. They rarely if ever measure whether doing this reduces community trust, solidarity, cohesion, organization, or activism in ways that might facilitate HIV transmission. 3. Many interventions are not best conceived of as interventions with individuals but rather with networks, cultures of risks, or communities. As such, randomizing individuals leads to effective interventions that diffuse protection through a community; but these are evaluated as ineffective because the changes diffuse to the control arm, which leads to systematic and erroneous reductions in the evaluated effectiveness as RCTs measure it. The paper ends by discussing research designs that are superior to individual-level RCTs at measuring whether an intervention reduces or increases new HIV transmission.The impact of the 2014 military conflict in the east of Ukraine and the Autonomous Republic of the Crimea among patients receiving opioid agonist therapies

4AbstractBackground: The COVID-19 pandemic has worsened the opioid overdose crisis in the US. Rural communities have been disproportionately affected by opioid use and people who use drugs in these settings may be acutely vulnerable to pandemic-related disruptions due to high rates of poverty, social isolation, and pervasive resource limitations. Methods: We performed a mixed-methods study to assess the impact of the pandemic in a convenience sample of people who use drugs in rural Illinois. We conducted 50 surveys capturing demographics, drug availability, drug use, sharing practices, and mental health symptoms. In total, 19 qualitative interviews were performed to further explore COVID-19 knowledge, impact on personal and community life, drug acquisition and use, overdose, and protective substance use adaptations. Results: Drug use increased during the pandemic, including the use of fentanyl products such as gel encapsulated “beans” and “buttons”. Disruptions in supply, including the decreased availability of heroin, increased methamphetamine costs and a concomitant rise in local methamphetamine production, and possible fentanyl contamination of methamphetamine was reported. Participants reported increased drug use alone, experience and/or witness of overdose, depression, anxiety, and loneliness. Consistent access to harm reduction services, including naloxone and fentanyl test strips, was highlighted as a source of hope and community resiliency. Conclusions: The COVID-19 pandemic period was characterized by changing drug availability, increased overdose risk, and other drug-related harms faced by people who use drugs in rural areas. Our findings emphasize the importance of ensuring access to harm reduction services, including overdose prevention and drug checking for this vulnerable population.The Impact of the Good Behavior Game, a Universal Classroom-Based Preventive Intervention in First and Second Grades, on High-Risk Sexual Behaviors and Drug Abuse and Dependence Disorders into Young Adulthood

6-18AbstractThe Good Behavior Game (GBG), a method of teacher classroom behavior management, was tested in first- and second-grade classrooms in 19 Baltimore City Public Schools beginning in the 1985-1986 school year. The intervention was directed at the classroom as a whole to socialize children to the student role and reduce aggressive, disruptive behaviors, confirmed antecedents of a profile of externalizing problem outcomes. This article reports on the GBG impact on the courses and interrelationships among aggressive, disruptive behavior through middle school, risky sexual behaviors, and drug abuse and dependence disorders through ages 19-21. In five poor to lower-middle class, mainly African American urban areas, classrooms within matched schools were assigned randomly to either the GBG intervention or the control condition. Balanced assignment of children to classrooms was made, and teachers were randomly assigned to intervention or control. Analyses involved multilevel growth mixture modeling. By young adulthood, significant GBG impact was found in terms of reduced high-risk sexual behaviors and drug abuse and dependence disorders among males who in first grade and through middle school were more aggressive, disruptive. A replication with the next cohort of first-grade children with the same teachers occurred during the following school year, but with minimal teacher mentoring and monitoring. Findings were not significant but generally in the predicted direction. A universal classroom-based prevention intervention in first- and second-grade classrooms can reduce drug abuse and dependence disorders and risky sexual behaviors.The Opioid/Overdose Crisis as a Dialectics of Pain, Despair, and One-Sided Struggle

8AbstractThe opioid/overdose crisis in the United States and Canada has claimed hundreds of thousands of lives and has become a major field for research and interventions. It has embroiled pharmaceutical companies in lawsuits and possible bankruptcy filings. Effective interventions and policies toward this and future drug-related outbreaks may be improved by understanding the sociostructural roots of this outbreak. Much of the literature on roots of the opioid/overdose outbreak focuses on (1) the actions of pharmaceutical companies in inappropriately promoting the use of prescription opioids; (2) “deaths of despair” based on the deindustrialization of much of rural and urban Canada and the United States, and on the related marginalization and demoralization of those facing lifetimes of joblessness or precarious employment in poorly paid, often dangerous work; and (3) increase in occupationally-induced pain and injuries in the population. All three of these roots of the crisis—pharmaceutical misconduct and unethical marketing practices, despair based on deindustrialization and increased occupational pain—can be traced back, in part, to what has been called the “one-sided class war” that became prominent in the 1970s, became institutionalized as neo-liberalism in and since the 1980s, and may now be beginning to be challenged. We describe this one-sided class war, and how processes it sparked enabled pharmaceutical corporations in their misconduct, nurtured individualistic ideologies that fed into despair and drug use, weakened institutions that created social support in communities, and reduced barriers against injuries and other occupational pain at workplaces by reducing unionization, weakening surviving unions, and weakening the enforcement of rules about workplace safety and health. We then briefly discuss the implications of this analysis for programs and policies to mitigate or reverse the opioid/overdose outbreak.The prevalence and types of gambling among undocumented mexican immigrants in New York City

49-65AbstractObjectives To examine the prevalence of gambling and types of gambling activities in a sample of undocumented Mexican immigrants. Design Non-probability cross-sectional design. Setting New York City. Sample The 431 respondents ranged in age from 18 to 80 (mean age 32), 69.7% were male. Results More than half (53.8%) reported gambling in their lifetime and of those most (43.9%) played scratch and win tickets or the lottery. In multivariate analyses men reported gambling more than women [2.13, 95% CI = (1.03, 4.38)]. The odds of gambling in their lifetime were higher among those reporting sending money to family or friends in the home country [2.65, 95% CI = 1.10, 6.38)], and those who reported 1-5 days as compared to no days of poor mental health in the past 30 days [2.44, 95% CI = 1.22, 4.89)]. Conversely, those who reported entering the U.S. to live after 1996 were less likely to report gambling [0.44, 95% CI = (0.22, 0.89)] as compared to those who had lived in the U.S. longer. Conclusion There is a need to further explore both the prevalence and the severity of gambling amongst the growing population of undocumented Mexican immigrants in the U.S.The role of access to integrated services at opioid agonist treatment sites in reaching 90-90-90 cascade in people who inject drugs in Ukraine : Country-level data

216AbstractINTRODUCTION: Opioid agonist treatment (OAT) is an effective means to prevent HIV transmission. Ukraine started integrating HIV services into OAT sites to improve people who inject drugs' (PWID) access to treatment.METHODS: Data from the national registry of OAT patients (n = 9,983) were analyzed. These data are collected from all 179 OAT sites countrywide. For the cascade, HIV-positive OAT patients (n = 4,084) were stratified into two categories: OAT alone (received OAT at one site and antiretroviral therapy (ART) at different location, n = 1,789) and integrated care (received OAT and ART at one location, n = 2,295) for comparison.RESULTS: Most HIV-positive OAT patients in Ukraine are male (85.6 %) and the mean age is 40.3 years old. The mean length of injecting before OAT is 17.2 years and the mean length on OAT is 4.2 years. All HIV-positive OAT clients are aware of their HIV status. The proportion of HIV-positive clients receiving ART was higher at integrated care sites compared to OAT alone sites (84.2 vs. 73.1 %, p- = 0.012); distribution of viral suppression among those receiving ART across the strata were 79.4 and 59.2 % for 'integrated care sites' vs. 'OAT only sites' respectively (p < 0.001).CONCLUSIONS: This analysis clearly demonstrates much better progress towards the 90-90-90 goals among those OAT patients who receive integrated care services (both OAT and ART) at one site at each stage of the HIV care cascade as compared to receiving OAT and ART at different sites. There is an urgent need to further expand the integration of OAT and HIV services in Ukraine."they look at us like junkies" : Influences of drug use stigma on the healthcare engagement of people who inject drugs in New York City

1AbstractBackground: People who inject drugs (PWID) are a medically and socially vulnerable population with a high incidence of overdose, mental illness, and infections like HIV and hepatitis C. Existing literature describes social and economic correlations to increased health risk, including stigma. Injection drug use stigma has been identified as a major contributor to healthcare disparities for PWID. However, data on this topic, particularly in terms of the interface between enacted, anticipated, and internalized stigma, is still limited. To fill this gap, we examined perspectives from PWID whose stigmatizing experiences impacted their views of the healthcare system and syringe service programs (SSPs) and influenced their decisions regarding future medical care. Methods: Semi-structured interviews conducted with 32 self-identified PWID in New York City. Interviews were audio recorded and transcribed. Interview transcripts were coded using a grounded theory approach by three trained coders and key themes were identified as they emerged. Results: A total of 25 participants (78.1%) reported at least one instance of stigma related to healthcare system engagement. Twenty-three participants (71.9%) reported some form of enacted stigma with healthcare, 19 participants (59.4%) described anticipated stigma with healthcare, and 20 participants (62.5%) reported positive experiences at SSPs. Participants attributed healthcare stigma to their drug injection use status and overwhelmingly felt distrustful of, and frustrated with, medical providers and other healthcare staff at hospitals and local clinics. PWID did not report internalized stigma, in part due to the availability of non-stigmatizing medical care at SSPs. Conclusions: Stigmatizing experiences of PWID in formal healthcare settings contributed to negative attitudes toward seeking healthcare in the future. Many participants describe SSPs as accessible sites to receive high-quality medical care, which may curb the manifestation of internalized stigma derived from negative experiences in the broader healthcare system. Our findings align with those reported in the literature and reveal the potentially important role of SSPs. With the goal of limiting stigmatizing interactions and their consequences on PWID health, we recommend that future research include explorations of mechanisms by which PWID make decisions in stigmatizing healthcare settings, as well as improving medical care availability at SSPs.Trends in Injection Risk Behaviors among People Who Inject Drugs and the Impact of Harm Reduction Programs in Ukraine, 2007–2013

104-114AbstractThe study examined trends in injection risk behaviors among people who inject drugs (PWIDs) and assessed the impact of harm reduction programs in Ukraine during 2007–2013. We performed a secondary analysis of the data collected in serial cross-sectional bio-behavioral surveillance surveys administered with PWIDs in Ukraine in 2007, 2008, 2011, and 2013. Using data from 14 Ukrainian cities, we assessed short-term trends in injection risk behaviors with the Cochran-Armitage test for trend and multivariable logistic regression models, adjusted for age, sex, region, marital status, education level, occupation, age at injection drug use initiation, experience of overdose, and self-reported HIV status. The overall test for trend indicated a statistically significant decrease over time for sharing needle/syringe during the last injection (p < 0.0001), sharing needle/syringe at least once in the last 30 days (p < 0.0001), and using a common container for drug preparation (p < 0.0001). The prevalence of injecting drugs from pre-loaded syringes was high (61.0%) and did not change over the study period. After adjusting for all significant confounders and comparing to 2007, the prevalence of sharing needle/syringe during the last injection was unchanged in 2008 (OR = 1.06, 95% CI = 0.92, 1.21), and declined in 2011 (OR = 0.18, 95% CI = 0.15, 0.22) and 2013 (OR = 0.17, 95% CI = 0.14, 0.21). Sharing needles/syringes in the last 30 days significantly decreased when compared to that in 2007 (2008: OR = 0.81, 95% CI = 0.74, 0.89; 2011: OR = 0.43, 95% CI = 0.38, 0.47; and 2013: OR = 0.31, 95% CI = 0.27, 0.35). The prevalence of using common instruments for drug preparation also decreased compared to that in 2007 (2008: OR = 0.88, 95% CI = 0.85, 0.91; 2011: OR = 0.85, 95% CI = 0.85, 0.90; and 2013: OR = 0.74, 95% CI = 0.71, 0.76). The observed reduction in the prevalence of injection risk behavior over time is encouraging. Our findings suggest that prevention programs in Ukraine have positive impact and provide support for governmental expansion of these programs.Understanding Prolonged Cessation from Heroin Use : Findings from a Community-Based Sample

123-132AbstractBackground: There is abundant literature describing heroin initiation, co-morbidities, and treatment. Few studies focus on cessation, examining the factors that motivate and facilitate it.Methods: The CHANGE study utilized mixed methods to investigate heroin cessation among low-income New York City participants. This paper describes findings from qualitative interviews with 20 former and 11 current heroin users. Interviews focused on background and current activities, supports, drug history, cessation attempts, and motivators and facilitators to cessation. Results: Participants found motivation for cessation in improved quality of life, relationships, and fear of illness, incarceration and/or death. Sustained cessation required some combination of treatment, strategic avoidance of triggers, and engagement in alternative activities, including support groups, exercise, and faith-based practice. Several reported that progress toward goals served as motivators that increased confidence and facilitated cessation. Ultimatums were key motivators for some participants. Beyond that, they could not articulate factors that distinguished successful from unsuccessful cessation attempts, although data suggest that those who were successful could describe more individualized and concrete-rather than general-motivators and strategies. Conclusions: Our findings indicate that cessation may be facilitated by multifaceted and individualized strategies, suggesting a need for personal and comprehensive approaches to treatment.Updating the Infection Risk Reduction Hierarchy : Preventing Transition into Injection

14-19AbstractCurrent approaches to prevention of blood-borne infections in injection drug users include referral to drug abuse treatment, access to sterile syringes, bleach disinfection of injection equipment, and education about not sharing equipment. However, rates of some blood-borne infections (e.g., hepatitis C virus) remain elevated among injection drug users, especially early after initiation into injection drug use. With lower infection rates in noninjectors and transition into injection drug use occurring most commonly among these noninjectors, prevention of transition into injection drug use as an additional step to reduce risk for acquisition and transmission of blood-borne infections merits closer attention.Urban as a determinant of health

i16-i26AbstractCities are the predominant mode of living, and the growth in cities is related to the expansion of areas that have concentrated disadvantage. The foreseeable trend is for rising inequities across a wide range of social and health dimensions. Although qualitatively different, this trend exists in both the developed and developing worlds. Improving the health of people in slums will require new analytic frameworks. The social-determinants approach emphasizes the role of factors that operate at multiple levels, including global, national, municipal, and neighborhood levels, in shaping health. This approach suggests that improving living conditions in such arenas as housing, employment, education, equality, quality of living environment, social support, and health services is central to improving the health of urban populations. While social determinant and multilevel perspectives are not uniquely urban, they are transformed when viewed through the characteristics of cities such as size, density, diversity, and complexity. Ameliorating the immediate living conditions in the cities in which people live offers the greatest promise for reducing morbidity, mortality, and disparities in health and for improving quality of life and well being.Urban health issues

53-69AbstractWe live in an increasingly interconnected world, as some like to say, a "global village." As in any village, social, economic and biophysical environments shape individual action and interaction, which, in turn, influence the quality of life and the health of inhabitants. Technology, information, media, food, goods and services, as well as environmental pollution and diseases are shared among villages, cities, countries and continents. Not only are these exchanges great in scope, but the magnitude and speed of interaction among individuals and populations is also increasing. For example, international trade grew 8.6% per year during the decade 1990-1999 (World Trade Organization, 2000a, b), with an estimated US$1.7 trillion in daily global trading (Lee, 2000). An estimated 760 million people traveled to international destinations in 2004 (World Trade Organization, 2005), and circumnavigation of the globe is now possible in a mere 36 hours (Smolinski, Hamburg, & Lederberg, 2003). Immigration contributes to global exchanges, with an estimated 175 million individuals spending at least one year in another country (United Nations, 2002). Additionally, approximately 17 million refugees and internally displaced persons migrate from their homes every year (United Nations High Commissioner for Refugees, 2004). These trends of growing interactions on the global scale shape the environments in which we live and which influence our well-being and our health.Vaccinating high-risk patients against influenza: Doing more to protect patients with asthma

We illustrate how PWID can be active agents promoting HIV, HCV, and overdose prevention. Recent Findings: We assessed drug users’ connections and interactions with others at risk for HIV/HCV in three cities: New York City (NYC), USA (n = 539); Pereira, Colombia (n = 50); and St. Petersburg, Russia (n = 49). In all three cities, the majority of participants’ network members were of a similar age as themselves, yet connections across age groups were also present. In NYC, knowing any opioid user(s) older than 29 was associated with testing HCV-positive. In NYC and St. Petersburg, a large proportion of PWID engaged in intravention activities to support safer injection and overdose prevention; in Pereira, PWID injected, had sex, and interacted with other key groups at risk. Summary: People who use drugs can be active players in HIV/HCV and overdose risk- reduction; their networks provide them with ample opportunities to disseminate harm reduction knowledge, strategies, and norms to others at risk. Local communities could augment prevention programming by empowering drug users to be allies in the fight against HIV and facilitating their pre-existing health-protective actions.
