Disparities in Lupus and the Role of Social Determinants of Health: Current State of Knowledge and Directions for Future Research.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. The complex relationships between race and ethnicity and social determinants of health (SDOH) in influencing SLE and its course are increasingly appreciated. Multiple SDOH have been strongly associated with lupus incidence and outcomes and contribute to health disparities in lupus. Measures of socioeconomic status, including economic instability, poverty, unemployment, and food insecurity, as well as features of the neighborhood and built environment, including lack of safe and affordable housing, crime, stress, racial segregation, and discrimination, are associated with race and ethnicity in the US and are risk factors for poor outcomes in lupus. In this scientific statement, we aimed to summarize current evidence on the role of SDOH in relation to racial and ethnic disparities in SLE and SLE outcomes, primarily as experienced in the U.S. Lupus Foundation of America's Health Disparities Advisory Panel, comprising 10 health disparity experts, including academic researchers and patients, who met 12 times over the course of 18 months in assembling and reviewing the data for this study. Sources included articles published from 2011 to 2023 in PubMed, Centers for Disease Control and Prevention data, and bibliographies and recommendations. Search terms included lupus, race, ethnicity, and SDOH domains. Data were extracted and synthesized into this scientific statement. Poorer neighborhoods correlate with increased damage, reduced care, and stress-induced lupus flares. Large disparities in health care affordability, accessibility, and acceptability exist in the US, varying by region, insurance status, and racial and minority groups. Preliminary interventions targeted social support, depression, and shared-decision-making, but more research and intervention implementation and evaluation are needed. Disparities in lupus across racial and ethnic groups in the US are driven by SDOH, some of which are more easily remediable than others. A multidimensional and multidisciplinary approach involving various stakeholder groups is needed to address these complex challenges, address these diminish disparities, and improve outcomes.

Patient powered research: an approach to building capacity for a hardly reached patient population to engage in cancer research.

BACKGROUND: Participating in clinical trials is a metric of high-quality cancer care and improves survival. However, Black individuals with cancer are less likely to be enrolled in clinical trials and experience a disproportionate burden of cancer mortality compared to Whites. Patient-engaged research is one potential strategy to address racial inequities in clinical trials, but little is known about best practices for engaging Black individuals and communities impacted by cancer in research partnerships. METHODS: We used a community engaged research approach to establish a patient advisory council (PAC) representative of the patient population served by a safety net hospital cancer center. We outline the process of establishing the PAC and the lessons learned. RESULTS: The inaugural PAC included 7 members representative of the cancer center's patient demographics. PAC members developed a patient centered vision, mission and action plan. PAC and community-academic research partners experienced the transformative power of centering the lived experiences of patients of color to promote health equity in cancer research. CONCLUSION: Establishing a patient advisory council at a safety net hospital cancer care center provided a platform for engaging a hardly reached population in patient centered research.

Participating in clinical trials is an important measure of high-quality cancer care and improves survival. However, Black individuals with cancer are less likely to participate in clinical trials and are more likely to die from cancer compared to Whites. Including Black patients as research partners is one way to improve racial equity in clinical trial participation. We established a patient advisory council (PAC) including patients and caregivers with similar racial demographics as the patients receiving care at a safety net hospital cancer center. PAC members partnered with the research team to develop a vision, mission, and action plan to improve research participation among patients of color. PAC members used their lived experiences and training from the research team to help develop a strategy to improve representation of patients of color in cancer research. This paper is focused on the PAC development process.

Assessing cancer center researcher and provider perspectives on patient engagement.

Participatory research approaches can help ensure research is culturally relevant and aligned with stakeholder priorities, but barriers exist between researchers and community stakeholders, particularly in communities of color. We developed a measurement tool for assessing oncology researcher and provider readiness to undertake patient-engaged research, and piloted this measurement tool among oncology researchers and providers at the hospital's cancer care center. A survey was developed by drawing from existing PCORI assessments as well as creating original questions, in an effort to develop an evidence-based survey tailored to this project. A total of 23 researchers and providers responded to the survey. The majority of respondents indicated that they were moderately or very familiar with the concept of patient-centered outcomes research. Most respondents had little to no experience engaging in participatory research and endorsed several barriers to engaging patients in the research process, including lack of experience and time. A mechanism for preparing and supporting researchers and providers is needed if cancer centers are to implement patient-powered research agendas as recommended by PCORI.

Association between plasma IL-6 response to acute stress and early-life adversity in healthy adults.

Increased production of peripheral cytokines and other pro-inflammatory markers has been linked to psychiatric disorders such as major depressive disorder and post-traumatic stress disorder. Recent research has pointed to early-life stress, particularly childhood maltreatment, as an independent and preventable risk factor for systemic inflammation in adulthood. Some data suggest that adults with a history of childhood maltreatment exhibit a heightened inflammatory response to acute stress challenge. To further elucidate the relationship between childhood maltreatment and pro-inflammatory cytokine production, we examined plasma IL-6 response to the Trier Social Stress Test (TSST) in 69 healthy adult subjects without depression or post-traumatic stress disorder. Serial plasma IL-6 concentrations were measured during a standardized psychosocial stressor in n=19 subjects with moderate-severe childhood maltreatment (MAL), and n=50 controls without maltreatment (CTL), as indicated by self-ratings on the childhood trauma questionnaire (CTQ). CTQ total scores were positively correlated with overall change in IL-6 response, as well as the maximum IL-6 concentration during the TSST. Greater acute IL-6 release and higher IL-6 concentrations over time were observed for the MAL group relative to the CTL group. Inflammation may be an important developmental mediator linking adverse experiences in early life to poor adult physical and mental health. The results of this preliminary study warrant further investigation in a larger sample.

Brain imaging and brain privacy: a realistic concern?

Functional neuroimaging has been used to study a wide array of psychological traits, including aspects of personality and intelligence. Progress in identifying the neural correlates of individual differences in such traits, for the sake of basic science, has moved us closer to the applied science goal of measuring them and thereby raised ethical concerns about privacy. How realistic are such concerns given the current state of the art? In this article, we describe the statistical basis of the measurement of psychological traits using functional neuroimaging and examine the degree to which current functional neuroimaging protocols could be used for this purpose. By analyzing the published data from 16 studies, we demonstrate that the use of imaging to gather information about an individual's psychological traits is already possible, but to an extremely limited extent.
