CDUHR AIDS Seminar – Typhanye Dyer – February 8, 2022
Tuesday, February 8, 2022, 10:30 am-11:30 am
Location: Zoom Webinar
Presented by: Typhanye V. Dyer, PhD, MPH
Presentation title: Utilizing Syndemics and Intersectional Frameworks in Substance Abuse Research for Marginalized, Priority Populations

This presentation will be on the history and use of syndemics in HIV research. Dr. Dyer will also cover the field of intersectionality research and how the two complement one another to provide context into the lived experiences of marginalized, high-risk, priority populations. Some foci will be on concepts and frameworks of both syndemics and intersectionality and slightly on measurement of syndemics via latent class analysis.

Typhane DyerTyphanye V. Dyer is an associate professor in the Epidemiology and Biostatistics Department at The University of Maryland School of Public Health, in College Park, MD. She received her doctorate from The UCLA Jonathan and Karen Fielding School of Public Health and completed her post-doctoral training at Johns Hopkins University. Her educational training is in infectious disease and social epidemiology, as well as community health, particularly focused on community-engaged research. Integrating theories and innovative methodologies from both disciplines, she strives to understand the broader social and structural processes that impact the health of the community.

Dr. Dyer is an epidemiologist and health disparities scholar whose research examines the influence of social, psychological, and behavioral factors on HIV/STI-risk in Black populations. She has over 20 years of experience conducting research exploring HIV and HIV-related outcomes among sexual minority men, as well as women. The majority of her research applies the concept of syndemics (complex, intersecting, synergistic psychosocial and structural barriers) to the lived experiences of Black sexual minority men (Black SMM), including exploring the intersections of trauma, poor mental health, criminal justice involvement and HIV/STI risk and acquisition for Black SMM. Regarding Black women, she uses a similar framework to develop an understanding of the impact of intersectional stigma on engagement in the HIV continuum of care for older cisgender Black women living with of at risk for HIV.

Presentation title: HIV Outbreak Among People Who Inject Drugs in Athens, Greece During an Era of Economic Hardship

Greece experienced an unprecedented fiscal crisis and economic downturn after 2009 that was soon followed by instability, political turbulence, and social struggles. Between 2011 and 2013, HIV spread quickly among people who inject drugs (PWID) in downtown Athens. The public health response included efforts by national public health authorities and drug use agencies but a major intervention was ARISTOTLE, a seek-test-treat-retain approach that consisted of multiple waves of respondent-driven sampling. In the same context, a US NIDA-funded project based on identifying risk networks of PWID recently infected with HIV was implemented (Transmission Reduction Intervention Project – TRIP; Sam Friedman, PI). This talk will summarize key aspects of the HIV outbreak among PWID in Athens, present the findings of ARISTOTLE and TRIP, and discuss future challenges for this population in Greece and beyond.

Presentation title: Principles and Metrics for Evaluating Oregon’s Drug Decriminalization Measure: Centering the Voices of People who Use Drugs

netherland-kral-2021-11-09Link to Video




In November 2020, Oregon voters passed an historic measure to decriminalize possession of small amounts of all drugs and invest substantially in healthcare, substance use disorder treatment, harm reduction, and social services for people who use drugs. Already, there is broad interest in evaluating the measure, and evaluations of the policy will be critical to the many jurisdictions that are seeking to replicate it. In an effort to improve evaluations of the measure and avoid some of the pitfalls of drug policy research, we convened a working group of experts and consulted with people who use drugs in Oregon to develop principles for an effective evaluation as well as metrics to measure the success of policy. This presentation will describe both the process we used as well as the principles and metrics derived from interviews with people who use drugs in Oregon.

CDUHR Methods Presentation – David Vanness – October 21, 2021 (Video)
Thursday, October 21, 2021, 1:00 pm-2:00 pm
Location: Zoom webinar
Presented by: David Vanness, PhD
Presentation title: An Introduction to Bayesian Statistics for Evaluation and Decision-Making


Link to Video




Uncertainty is the reason why we do evaluation research… and the reason why our research often fails to lead to change. When we use Bayesian principles to quantify uncertainty, we can help decision-makers to better understand the consequences of making decisions based on current knowledge and the potential benefits and costs of engaging in further research. In this talk, we will introduce the fundamental principles of Bayesian statistical inference and briefly talk about commonly-used statistical packages, including WinBUGS, JAGS and STAN. We will then briefly discuss applications of Bayesian inference to multi-level modeling, meta-analysis and clinical trial design. We will conclude with a preview of how Bayesian principles are being incorporated into the Multiphase Optimization Strategy (MOST) to provide a new platform for optimizing and evaluating multi-component behavioral and biobehavioral interventions.

David VannessDavid J. Vanness, PhD, is a Professor of Health Policy and Administration in the College of Health and Human Development at Penn State University (University Park, Pennsylvania). He received his doctorate in economics from the University of Wisconsin-Madison and has served on the faculty of the Mayo Clinic in Rochester, Minnesota and the University of Wisconsin School of Medicine and Public Health. Professor Vanness has taught short courses in Bayesian statistics for the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) for over 15 years and was the founding Chair of ISPOR’s Statistical Methods in Health Economics and Outcomes Research Special Interest Group. He currently serves as methodological Associate Editor for the journal Value in Health.

Dr. Vanness’ research uses computational methods to translate statistical evidence into improved decision-making in the areas of health technology assessment, health care policy evaluation and intervention optimization. He is currently working with Professor Linda Collins to incorporate Bayesian statistical decision-making principles into the Multiphase Optimization Strategy (MOST) and serves as a methodological consultant to the Heart-to-Heart 2 project (Professors Gwadz and Collins).

CDUHR AIDS Seminar – Yusuf Ransome – October 12, 2021 (Video)
Tuesday, October 12, 2021, 10:30 am-11:30 am
Location: Zoom webinar
Presented by: Yusuf Ransome, DrPH
Presentation title: Social Cohesion and Social Capital: Their Role in HIV Prevention in the United States




Link to Video



In this presentation, Dr. Ransome will discuss social capital and social cohesion as a determinant of HIV infection risk for individuals, and HIV incidence at the population level, by providing a theoretical overview and empirical results from his work and others, as well as results from randomized controlled studies. He will conclude with paths forward and how researchers can integrate social cohesion and social capital into their current work and build modules to add to their existing behavioral or biomedical interventions.

At the end of this session, participants will be able to describe the differences between structural and cognitive forms of social capital, explain some of the limitations of current metrics to assess social capital in public health, and explain why alternate measures are being proposed and the reasons why social capital development is being recommended. They will be able to list some mechanisms through which social capital influences several HIV care continuum outcomes (e.g., diagnosis and ART adherence), and evaluate published studies on social capital and HIV with respect to theory and measurement, and the quality of the articles conclusion.


Yusuf RansomeYusuf Ransome, DrPH, completed a Bachelor of Science at Brooklyn College of the City University of New York, an MPH from the University of Michigan, a DrPH from Columbia University Mailman School of Public Health, and a postdoc at Harvard T.H. Chan School of Public Health. Currently, he is an Assistant Professor in the Department of Social and Behavioral Sciences at Yale School of Public Health.

Dr. Ransome investigates how social and cultural determinants (specifically, social capital & social cohesion, religion & spirituality) influence health and socioeconomic mobility, and can be leveraged to reduce disparities in HIV infection and alcohol use disorders. Dr. Ransome currently has a K01 Mentored Research Scientist Development Award from the National Institute of Mental Health to study the direct association and underlying mechanisms between social capital and late HIV diagnosis in the United States.

CDUHR Methods Presentation – John W. Jackson – September 29, 2021 (Video)
Wednesday, September 29, 2021, 11:00 am-12:00 pm
Location: Zoom webinar
Presented by: John W. Jackson, ScD
Presentation title: An Introduction to Causal Decomposition Analysis for Studying Disparities in Health



Link to Video




Brief Description: Two of the most popular tools to describe how factors contribute to disparities are mediation analysis (from epidemiology) and the Oaxaca-Blinder decomposition (from economics). In this talk, Dr. Jackson will review their different inferential goals and introduce a unifying perspective under the potential outcomes framework. He will also show how this unifying perspective builds upon both approaches by allowing us to separately consider how covariates are used to define disparities and adjust for confounding of explanatory factors.

John JacksonJohn W. Jackson is Assistant Professor in the Departments of Epidemiology and Mental Health at the Johns Hopkins Bloomberg School of Public Health. Dr. Jackson earned his ScD in epidemiology from the Harvard School of Public Health in 2013 with a concentration in psychiatric epidemiology. From 2011 to 2014, he trained in the Division of Pharmacoepidemiology and Pharmacoeconomics at Brigham and Women’s Hospital as a predoctoral trainee and postdoctoral research fellow, where his work focused on the safety and utilization of antipsychotic medications, as well as methods for comparative effectiveness research. Dr. Jackson’s current research focuses on understanding and reducing the excess morbidity and mortality in patients with mental illness, and uses state-of-the-art methods to provide insight about the effectiveness of potential interventions.

Presentation title: Drug Overdose Mortality in Different Hispanic Heritage Groups


Link to Video



Although Hispanics as an overall group experience lower rates of drug overdose mortality than their Non-Hispanic White or Black peers, the overall Hispanic category masks wide variation in risk of overdose mortality. In this presentation, we will compare recent US rates of drug overdose mortality between different Hispanic heritage groups, also examining variation by age, sex, nativity, and specific drugs involved in overdose. In addition to highlighting mortality data, the presentation will also discuss possible explanations and implications for the alarmingly high rates of drug overdose deaths in Hispanics of Puerto Rican heritage living stateside.
