Racism, Adversity, and Child Health

Racial discrimination is a toxic psychosocial stressor that can affect individuals and communities of color.  This presentation will explore how common are perceptions of racism in minority children and explore the research on its effects on child health.  An overview of the development of the PRaCY—a psychometrically valid questionnaire to measure perceptions of racism in children will follow, followed by a model that describes how racism “gets under the skin” to contribute to poor health outcomes as well as racial and ethnic health disparities throughout the lifecourse. Finally, we’ll discuss the inclusion of racism into the expanded definition of “adverse childhood experiences” (ACEs).

Exploring the Human Pathome using Real-World Data

Pathome-wide association scans (PWAS) offer an alternative to the conventional one-disease-at-a-time paradigm. PWAS analysis displays negative, neutral, and positive associations across all diseases simultaneously without the filter of publication bias. Densely annotated displays allow for the visualization of large-scale associations, revealing how potential biomarkers are associated with disease clusters.  A practical example is presented using a massive insurance-claims database to explore how red-cell size variation is related to the presence, onset, and risk of diseases.

Living laboratories: Building Clinical Programs with Impact

There is a steady flow of patients with special health care needs aging with their conditions. The demand to create appropriate clinical programs has grown accordingly. Dr. Wright would like to discuss a framework for clinical program development and evaluation, from a community based participatory research outset with implementation science tenets. As case study, she will use the Center for Special Health Care Needs’ newest programs: Cerebral Palsy and Sickle Cell.

Leading multi-disciplinary teams has been a highlight of Dr. Charmaine Wright’s career. A dual-trained internal medicine and pediatric primary care physician, she attended Harvard for college, medical school, and residency. Following residency, she completed a Robert Wood Johnson Clinical Fellowship at the University of Pennsylvania and joined faculty. As a med-peds primary care physician caring for complex patients, medical educator mentoring residents, and health services and clinical researcher dedicated to improving health disparities, she is passionate about implementing teams and programs that work for our most vulnerable patients. She has implemented RCT’s in community based settings and disseminated intervention programs for young adults who have been incarcerated and who have chronic disease. She works to bridge the gap between pediatric and adult care for patients with childhood-acquired medical conditions as the medical director of the Center for Special Health Care Needs.

Behavioral Economic Insights into Physician Tobacco Treatment Decision Making

Physicians self-report high adherence rates for Ask and Advise behaviors of tobacco dependence treatment, but are much less likely to engage in “next steps” consistent with sophisticated management of chronic illness.  Important presuppositions regarding the potential “success” of tobacco-related patient interactions are likely limiting physician engagement by favoring the most secure visit outcome despite the limited potential for health gains.  Innovative approaches to counteracting the cognitive biases limiting estimations of success probabilities seem to effectively reverse this pattern and provide clues to improving the adoption of target clinical behaviors.  Given the enormous access the healthcare system has to dependent patients, re-thinking longstanding traditions may have a profound impact on the tobacco epidemic. 

Dr. Leone is an Associate Professor of Medicine at the University of Pennsylvania, and direct Penn’s Comprehensive Smoking Treatment Program.  He has been a PI, co-investigator and study physician on numerous studies of tobacco dependence treatment, with a focus on the social science of tobacco control and treatment decision-making.  He has been active in the publication of a number of treatment guidelines and policy position statements, and remains a strong advocate for adoption of novel, evidence-based approaches to increasing the effectiveness of provider-based care.


Social Media-Based Parenting Intervention for Postpartum Depression

Maternal depression is common among women following childbirth. Depression adversely impacts a mother’s ability to parent. Current psychosocial and pharmacological therapy are effective at reducing depressive symptoms but may not improve parenting practices. In addition, few affected women successfully seek or engage in treatment. Social media and internet-based interventions hold promise for treating postpartum depression and resulting parenting dysfunction while addressing barriers to engagement in treatment. At the conclusion of this talk, participants will be able to

1)       Describe the prevalence of postpartum depression and its effects on parenting practices

2)       Explain the effectiveness of current treatments for postpartum depression and barriers to treatment participation

3)       Understand the potential role of social media and internet-based interventions

As a researcher, he has been the principal investigator on a number of federal research grants in the field of early childhood.


Zeroing in on Ovarian Cancer

Nearly a quarter of a million new cases of ovarian cancer are diagnosed worldwide every year. Unfortunately, we still do not have an effective screening tool for early detection and current treatment options are not curative. As a result, the case-to-fatality ratio is 3-4 times higher than breast cancer and the five-year survival rates remain poor. However, new insights into the pathogenesis of ovarian cancer are having direct clinical impact on new and innovative prevention strategies and early detection approaches. In addition, new insights from genomic studies are opening up avenues for novel targeted approaches to attack unique vulnerabilities in this disease. This presentation will discuss the latest advances in ovarian cancer pathogenesis, genomics, and strategies to improve prevention, early detection, and treatment.

She is the principal investigator on an ACCEL Pilot Grant that has engaged stakeholders in the development of a family-based psychosocial care model for congenital heart disease using online crowdsourcing methods. Dr. Sood is also Co-Vice Chair of the Cardiac Neurodevelopmental Outcome Collaborative (CNOC), co-leads the Patient/Family Support learning lab within the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC), and is on the editorial board for Clinical Practice in Pediatric Psychology.



This presentation focuses on describing three randomized trials designed to identify intervention strategies that can  increase colorectal cancer screening in health system primary care patient populations. The studies, which were supported by the National Cancer Institute, American Cancer Society, and Patient Centered Outcomes Research Institute, were conducted in three different health systems and primary care practice patient populations: 1) general patients, 2) African American patients, and 3) Hispanic patients. The presentation also highlights the need to develop learning health care systems that can support and sustain implementation of evidence-based cancer prevention and control interventions in routine care. A collective impact learning community strategy that can be used to catalyze this process is described. Application of this strategy is discussed relative to interventions intended to increase health system colorectal cancer and lung cancer screening rates.

Bifactor Modeling of Multifaceted Constructs in HealthCare Research

Many constructs in social, behavioral, and health care research are measured by multiple related domains. However, there is a long-standing and unresolved debate on how to measure and test such multifaceted constructs. Researchers often have to choose between two problematic approaches for analyzing multifaceted constructs: the total score approach and the individual score approach. Both approaches can result in conceptual ambiguity. We recommend the bifactor model as a more advantageous approach for testing multifaceted constructs. The bifactor model is comprised of a general factor that accounts for the commonality shared by the domains, and multiple specific factors, each of which accounts for the unique influence of the domains over and above the general factor. The bifactor model combines the advantages but avoid the drawbacks of the two existing methods and can lead to greater conceptual clarity. We illustrate the bifactor approach by examining the relations of multifaceted well-being to biomarkers.
