Metabolomic Profiling of Racial Disparity
Description

Tonsillectomy ± adenoidectomy (T\&A) is one of the most common surgical operations with over 500,000 pediatric T\&As performed annually in the United States. Unfortunately, despite advances in anesthetic and surgical techniques, moderate-severe post-tonsillectomy pain (PTP) remains a significant problem affecting up to 62% of children. PTP is thought to arise from pharyngeal mucosal inflammation, which produces local nerve irritation and pharyngeal muscle spasm. Patient factors and surgical techniques also play major roles. Race is an important phenotypic risk factor for moderately severe early PTP. The underlying molecular basis of this differential pain experience is presently unknown. This gap in knowledge means that therapies are poorly targeted and often unsuccessful. Indeed, treatment options for PTP have not advanced substantively for many years. Metabolomics provides novel opportunities to investigate common and unique "metabolic signature" of PTP through the analysis of low molecular weight compounds produced in response to tissue injury. Therefore, the central themes of this proposal are that (1) PTP is a complex process that may be determined by molecular level factors such as preoperative systemic inflammation and metabolic profile, and (2) these molecular level factors may explain the excess burden of PTP among minority children. Here the investigators seek to utilize a combined clinical, biological and untargeted metabolomics approach to identify candidate small and large serum molecules that may influence the frequency and severity of PTP in children across racial groups. This approach to exploring the molecular basis of PTP is novel and knowledge from the study should substantially enhance understanding of the mechanisms underlying pediatric PTP - and narrow the racial disparities in post-operative pain.

The Care Tracker Study: Using Patient-Reported Data to Address Racial Disparity in Cancer Treatment
Description

This study assesses the feasibility and acceptability of a brief electronic patient-reported outcome (ePRO) tool that allows patients to self-identify impending delays. The risk of treatment delays according to tumor type and race will be measured by both ePRO and electronic health record (EHR) tools. Data from this study and the association of social determinants of health could be useful to flag patients at risk of delay and due timely intervention for modifiable treatment barriers. The prediction of the risk of treatment delay will be helpful to design another study using electronic tracking systems to prevent cancer treatment delays. The long-term goal of this research is to alert care teams when patients may be at risk of treatment days and to help patients get treatment faster. It was planned to enroll a total of 240 subjects with newly diagnosed cancer. Sixty colorectal and 180 breast cancer patients will be included.

Treating Genital Herpes Infection to Reduce Racial Disparities in the Risk of Severe Maternal Morbidity
Description

Severe Maternal Morbidity (SMM) has been associated with maternal mortality, fetal risk, and long-term maternal risk. African American (AA) women are at consistently higher risk than White women. However, factors contributing to these racial disparities are largely unknown and commonly known factors have not been able to explain them, so strategies to reduce them are absent. CDC reports that the rate of GHSV infection is 4 times higher in AA than White women. Studies have shown that pregnant women with genital herpes simplex virus (GHSV) infection are at higher risk of SMM and that treating women with GHSV using existing anti-herpes medications could reduce SMM risk. To address the question of racial disparities in SMM and examine the comparative effectiveness of treating women with GHSV infection to reduce the risk of SMM, the investigators are conducting a large cohort study with a two-stage design, combining an EMR-based cohort (Stage I) with a sub-cohort interview (Stage II) to examine the impact of confounders not available from EMR data. Based on status of GHSV and treatment, 4 cohorts of women will be established: (1) those with GHSV infection receiving treatment early in pregnancy; (2) those with GHSV infection receiving treatment later in pregnancy; (3) those with GHSV infection untreated during pregnancy; and (4) those without GHSV. Given that racial disparities in SMM present serious challenges, the study will provide much needed data to address the effectiveness of treating GHSV on reducing racial disparities in SMM.

The Influence of Beetroot Juice on Racial Disparities in Vascular Health
Description

Black adults are 30% more likely to die from cardiovascular disease (CVD) compared to White adults, and more than half of this racial disparity in cardiovascular mortality may be attributed to the substantially greater prevalence of high blood pressure and vascular dysfunction in Black adults. Nitric oxide (NO) is a potent signaling molecule and key regular of vascular function that is suspected to be reduced in black individuals, but can be enriched by dietary nitrate (e.g., arugula, spinach, beets). The purpose of this study is to test the hypothesis that increasing NO bioavailability via nitrate-rich beetroot juice (BRJ) will lower blood pressure and improve vascular health in Black adults.

Shared Decision Making to Address Racial Disparities in Oral Anticoagulation in NVAF
Description

The study is a pilot analysis using a decision on the risk and benefits of oral anticoagulation for stroke reduction for patients with non-valvular atrial fibrillation. This study is a feasibility and acceptability analysis but will also measure preliminary effectiveness measures. The investigator hypothesizes that a patient decision support tool will increase decision quality and secondarily increase the use of oral anticoagulation in Black patients with non-valvular atrial fibrillation.

Reducing Racial Disparities in Severe Maternal Morbidity
Description

There is a paucity of research examining the intersection of race, ethnicity, maternal safety bundles, doulas, and maternal outcomes in Black women at increased risk of severe maternal morbidity and mortality. The proposed mixed-methods study is the first systematic investigation of pregnancy complications and outcomes among Black women with whom maternal safety bundles are being implemented including racial disparities, hemorrhage, and hypertension. Additionally, through the analysis of secondary state level data, this study will examine perinatal care, maternal outcomes, and healthcare utilization of Black women at increased risk of severe maternal morbidity and mortality compared with non-Latino white women. Finally, through individual interviews with Black women and focus groups with obstetric health providers and doulas, the study will examine disparities and improve care by creating and disseminating a set of practice recommendations for maternity care for Black women at increased risk of morbidity and mortality. Research has not yet examined the intersection of race/ethnicity, doulas, and quality improvement (QI) interventions, such as maternal safety bundles, on reducing SMM and mortality among non-Hispanic Black (NHB) women. The overall goal of this mixed-methods study is to use analysis of existing big data and the evaluation of two interventions to ultimately develop targeted recommendations for addressing these inequities. Our approach leverages multiple data sources to study maternal outcomes and access to care during the prenatal, birth, and postpartum periods in order to identify commonalities among women who experienced SMM and use those findings to create a risk profile of women who are more likely to experience SMM; examine the implementation of maternal safety bundles on SMM and MM outcomes for women up to 1 year postpartum (Intervention 1); gather in-depth data from obstetric care providers on factors that support or hinder safety bundle implementation (Intervention 1); and gather in-depth data from individual women and doulas on facilitators of barriers to the use of doulas to improve care and address inequities (Intervention 2).

Development of a New Early Detection Test to Reduce Racial Disparities in Endometrial Cancer (EC) Death Rates
Description

This phase I trial investigates the development of a new early detection test to reduce racial disparities in endometrial cancer death rates. DNA samples collected from a tampon may be able to be used to detect endometrial cancer. Studying information from focus groups and vaginal samples of African American and white women may help researchers develop a less invasive and painful test to detect endometrial cancer. The purpose of this trial is to perform a demonstration project of tampon self-collection, assess percentage of samples returned; total and endometrial derived DNA quantity and quality, preliminarily test previously validated DNA methylation markers that may discriminate endometrial cancer from normal endometrium in tampon specimens.

The Influence of Mitochondrial-Derived Reactive Oxygen Species on Racial Disparities in Neurovascular Function
Description

Black individuals are at increased cardiovascular disease risk. The central goal of the study is to determine if mitochondrial reactive oxygen species influence blood vessel function and nervous system regulation of blood pressure differentially in black, compared to white individuals. These findings may help to explain a potential mechanism that contributes to racial disparities in blood pressure and cardiovascular disease risk. A secondary goal is to determine if mitochondrial reactive oxygen species improves blood pressure and vascular function in individuals with elevated blood pressure and stage 1 hypertension.

Exploring Racial Disparities in Sleep Health and Neurocognitive Function
Description

Despite longer life expectancies due to combination antiretroviral therapy (cART), the prevalence of HIV-associated neurocognitive disorders (HAND) persists thus affecting 52% of the HIV population. Poor sleep quality is commonly reported in older adults and has been related to neurocognitive impairments. This is concerning given studies have shown that up to 75% of adults with HIV experience poor sleep, and by 2020, 70% of adults with HIV will be age 50 and older. It is important to examine sleep quality as it relates to neurocognitive function and HAND in older adults with HIV given its negative impact on cART adherence. Compared to Whites with HIV, African Americans (AA) are disproportionately affected by HIV and are more likely to experience poor sleep quality. This primary goal of this 1-year cross-sectional study is to examine racial differences in sleep quality and neurocognitive function among 60 African Americans and Whites with HIV (age 50+).

Malnutrition, Diet and Racial Disparities in Chronic Kidney Disease (CKD)
Description

In the United States, African Americans are 3.6 time and Hispanics 1.5 times more likely to suffer from chronic kidney disease and need dialysis treatment for life, when compared to the non-Hispanic Whites. Unfortunately many dialysis patients die, so that after 5 years only less than 35% are still alive. Dialysis patients who appear malnourished or who have muscle and fat wasting are even more likely to die. Interestingly, among dialysis patients, minorities (African Americans, Hispanics and Asian Americans) usually survive longer than the non-Hispanic Whites. If the investigators can discover the reasons for these so-called "racial survival disparities" of dialysis patients, the investigators may be able to improve survival for all dialysis patients and maybe even for many other people who suffer from other chronic diseases. During this 5 year study the investigators would like to test if a different nutrition and diet can explain better survival of minority dialysis patients. The investigators will also test if in additional to nutrition there are 2 other reasons for better survival of minority dialysis patients, namely differences in bone and minerals and differences in social and psychological and mental health. The investigators plan to study 450 hemodialysis patients every 6 months in several dialysis clinics in Los Angeles South Bay area. These subjects will include 30% African Americans, 30% Hispanics, 30% non-Hispanic Whites and 10% Asians. Every 6 months the investigators will examine their nutritional conditions, dietary intake, psycho-social conditions and quality of life, and will recruit 75 new subjects to replace those who left our study as a result of kidney transplantation, death or other reasons. Hence, the investigators estimate studying a total of 1,050 hemodialysis patients over 5 years. Clinical events such as hospital admissions and survival will be followed. Blood samples will be obtained every 6 months for measurements of hormones and "biomarkers", and the remainder of the blood will be stored in freezers for future measurements. The investigators plan to design and develop race and ethnicity specific nutritional risk scores and food questionnaires and will test some of these scores in larger national databases of hemodialysis patients. Almost a year after the study starts, the investigators also plan to do additional tests of body composition and dietary intake in a smaller group of these patients at the GCRC.

Racial Disparity in Barrett's Esophagus
Description

The goal of the proposed research is to investigate the molecular mechanisms of racial disparity in Barrett's esophagus (BE), the premalignant lesion of esophageal adenocarcinoma. Specifically, the investigators hypothesize that environmental factors, genetic factors, and potentially gene environment interactions play crucial roles in the observed racial disparity in developing Barrett's esophagus. Patients are recruited through UNC hospitals prior to scheduled esophagogastroduodenoscopy (EGD). Participants complete a questionnaire, have body measurements obtained, and have blood, biopsies, and gastric aspirate collected. Participants also complete a 24 hour pH impedance test.

Factors Influencing the Racial Disparity in Sudden Infant Death Syndrome (SIDS)
Description

The overall purpose of this investigation is to better understand factors contributing to the high incidence of prone sleep positioning in African-American infants. In addition, the investigators are interested in investigating other races and ethinicities to understand their beliefs and perceptions and determine differences socioeconomically and socioculturally within and between groups. The investigators will address the following specific aims: (-) To compare knowledge, attitudes, and practices regarding infant sleep position in parents of higher and lower SES. (-) To identify risk factors for non-use of recommended supine sleep position in families with higher and lower SES (-) to develop a phenomenologic understanding of the decisions made by parents of higher SES and lower SES who do nt use recommended supine sleep position, using qualitative techniques.

Family Acceptance Project Online (Pilot RCT)
Description

Research shows that sexual and gender minority youth (SGMY) experience high rates of mental health problems and other challenges (e.g., social, academic). A major factor that leads to these challenges is family rejection (family behaviors and reactions that minimize, deny, ridicule and attempt to prevent or change a child's sexual orientation, gender identity and gender expression). Racial and ethnic minority youth experience the highest rates of family rejection and related health risks. The Family Acceptance Project (FAP) is a research, education, and intervention initiative that was founded more than 20 years ago to help diverse families learn to support and affirm their SGMY. FAP's Family Support Model is grounded in the lived experiences of diverse SGMY and families and uses a culture-based family support framework that enables parents and caregivers to change rejecting behaviors that FAP's research has shown contribute to health risks and increase supportive and accepting behaviors that promote well-being for SGMY. The overall goal of this research project is to evaluate a nine-week online version of FAP's Family Support Model (FAP-O). The investigators will specifically study how FAP-O: 1. Promotes parent/caregiver acceptance and support of their sexual and gender minority youth. 2. Increases family bonding and communication. 3. Increases SGMYs' feelings of pride in being LGBTQ+ and more hopeful about the future. 4. Leads to reductions in mental health problems reported by SGMY who experience family rejection. Before receiving FAP-O's family support services, racial and ethnic minority SGMY (ages 14 to 20) and their caregivers will complete an initial pre-test survey. After completing this initial (baseline) survey, half of the families will participate in program sessions. Following the first round of sessions, all participants will complete an immediate follow-up survey, with an additional survey conducted six months after this. These surveys help us learn if FAP-O impacts the project's goals above. After the final survey, the other half of the families will attend program sessions. The investigators will also ask SGMY and caregivers to share what they liked about the program and their guidance for enhancing it.

Effect of the HCC Liver-Link Intervention
Description

Mortality rates for hepatocellular carcinoma (HCC) have risen in the US over the past two decades, disproportionately impacting Black patients with chronic liver disease5,6. Black patients are 50% less likely than White patients to receive curative therapies for HCC even when presenting with early stage disease7,8. Reasons for disparities in mortality are in part related to failure to progress through the complex HCC care continuum to access curative therapies as a result of the unequal distribution of social and structural determinants of health (SSDOH)9,10. SSDOH are the social conditions that influence individual and group differences in health11. For example, investigators found that Black patients with early stage HCC were more likely than White patients to have ongoing alcohol and substance and as a result were not candidates for liver transplantation (LT)7. In addition, data from our prospective cohort study demonstrated that Black patients with HCC have a higher burden of poor SSDOH that than their White counterparts, including higher rates of poverty, educational achievement less than high school and lapses in subspecialty care. The downstream consequences of these inequities including poor health-related knowledge and social needs are being increasingly targeted for improvement by hospital systems and providers in cancer care. However, there are currently no interventions designed to target social determinants or downstream social needs and eliminate racial disparities in HCC care. Successful health disparities interventions have been culturally tailored and multi-level12. Therefore, an intervention that successfully reduces disparities in HCC outcomes should have these characteristics and address both patient- and system-level SSDOH. The HCC Liver-Link intervention investigators propose to develop is designed to: a) improve patients' HCC-related disease and treatment knowledge; b) screen patients for social needs and substance use and refer to social work for linkage to local services; and c) use our multidisciplinary HCC tumor board to facilitate linkage to subspecialty HCC cancer care. Earlier portions of this research project were devoted to developing the education program component of the HCC Liver-Link intervention. This intervention, a full multi-level intervention designed to address patient- and system-level SSDOH variables and facilitate access to curative HCC therapies (liver transplantation and resection) in a cohort of Black patients with Barcelona Clinic Liver Cancer prognosis stage 0, A and downstaged B disease underwent pilot testing in a previous project. The aims of this portion of the study are to estimate the effect of the HCC Liver-Link intervention on the time to receipt of curative therapies and HCC related knowledge in black patients with HCC. Toward that end, investigators will conduct a multi-center, pilot randomized controlled trial to test the multi-level intervention in 40 black BCLC 0, A or downstaged B disease patients who will be followed for 6 months or until waitlisted for liver transplant.

Vascular Effects of Acute Sodium (VEAS) Study
Description

This IRB will cover a current clinical trial (NCT04244604) that was started at Auburn University (AU IRB#19-390), the Principal Investigator's prior institution, and is supported by his NIH Career Development Award (NHLBI K01HL147998). About nine out of ten Americans overconsume dietary salt. Compared to other racial groups, Black individuals are more prone to salt-sensitive hypertension and negative cardiovascular conditions associated with high salt intake. However, there is a critical need to determine the reasons behind and mechanisms that contribute to these racial disparities. Both acute (single meal) and chronic high-dietary sodium cause small but important increases in blood sodium concentration that are associated with altered blood pressure regulation and blood vessel dysfunction. However, racial differences in these measures have not been examined. This is important because Black individuals generally exhibit lower circulating concentrations of hormones (e.g., renin, aldosterone, angiotensin 2) that buffer changes in body sodium to regulate blood pressure, and this could make them more vulnerable to the negative effects of a high-sodium meal. Therefore, the purpose of this study is to determine whether there are racial differences in blood pressure regulation and blood flow after a high-sodium meal. The investigators will assess blood pressure regulation, blood vessel stiffness, and the blood vessel's ability to dilate before and after a high-salt meal and a low-salt control meal (both meals are low-salt tomato soup with varied added salt). The investigators will also collect blood and urine to measure sodium and determine biochemical changes that may be contributing to racial differences in cardiovascular function.

The Influence of Race and MitoQ Supplementation on Skin Blood Flow in the Cold
Description

Individuals who operate in cold weather are at risk of developing cold injuries, for example, frostbite. They also often experience a loss of hand function and joint mobility due to a decrease in skin temperature and blood flow. In addition, the risk of getting a cold injury is higher in the Black population compared to other racial and ethnic groups. Increases in oxidant compounds can cause the blood vessels in the skin to narrow and decrease skin temperature in the cold. However, it is unknown whether the higher risk of cold injury in Black individuals is because of a greater amount of oxidant compounds in the blood vessels. The purpose of this research is to see if an antioxidant supplement called MitoQ can help to improve skin temperature and blood flow in the cold and if the improvement is greater in Black individuals.

Potassium, Hydration, Cardiovascular, and Kidney Study
Description

Compared with White Adults, Non-Hispanic Black Adults are at an elevated risk of developing cardiovascular disease (CVD) and end stage chronic-kidney disease (CKD), two of the leading causes of death in the United States. Inadequate hydration status is associated with risk factors for both CVD and CKD. Prior data show that Black individuals are less likely to be adequately hydrated when compared with their White counterparts. Further, socioeconomic factors have been shown to influence hydration practices. Inadequate hydration influences certain hormones that regulate blood volume and impact blood pressure, but increasing potassium intake may provide some positive effects on normalizing these hormones and blood pressure. Black adults, in particular, are more likely to consume less potassium, have inadequate hydration, and tend to have higher blood pressure. As such, there is a critical need for effective strategies to address racial disparities in hydration and resultant health consequences; as well as establish the role of socioeconomic factors contributing to hydration. Therefore, the investigators are seeking to test the investigators' central hypothesis that water with a potassium supplement will improve hydration and cardiovascular health in young White adults (n = 20, 10 females, 10 males), and to a greater extent in young Black Adults (n = 20, 10 females, 10 males. The investigators will assess measures of blood pressure, arterial stiffness, and biomarkers in the urine and blood samples prior to and following a 14-day hydration intervention of 1) bottled water and 2) bottled water with potassium supplementation (2000mg potassium/day).

Patient-Portal vs Text-based Hypertension Monitoring Among Black Medicaid/Medicare Patients
Description

The coronavirus disease 2019 (COVID-19) pandemic has uprooted conventional health care delivery for routine ambulatory care, requiring health systems to rapidly adopt telemedicine capabilities. The digital divide, has been well documented with lower rates of technology and broadband adoption among racial/ethnic minorities. Additionally, Black patients suffer a disproportionate burden of hypertension and cardiovascular disease. This study will implement a text-based home hypertension monitoring program among Black Medicaid patients with hypertension and cardiovascular disease (CVD) and compare its uptake to the currently available blood pressure monitoring program using the patient portal that is integrated into the electronic health record (EHR).

Metformin Use to Reduce Disparities in Newly Diagnosed Breast Cancer
Description

Breast cancer is one of the most common malignancies in women globally, with \~1.4 million new cases diagnosed annually Breast cancer is one of the leading causes of cancer-related morbidity and mortality among women worldwide. While diabetes/insulin-resistance and breast cancer are distinct diseases, insulin-signaling plays a central role in both illnesses. Insulin activates key cancer processes including epithelial-mesenchymal transition (EMT), tissue inflammation, motility, and angiogenesis. There are key opportunities to impact and prevent hyperinsulinemia during breast cancer prevention, surgical assessment, and chemotherapy. Given the high prevalence of undiagnosed pre-diabetes and diabetes in the United States and worldwide, preoperative screening to identify such patients prior to surgical intervention is warranted. While it is not standard of care to test for insulin-resistance during the course of breast cancer screening and treatment, it is standard of care to screen and test high risk women for insulin-resistance as part of whole woman care. Given the important role insulin signaling plays in driving signaling pathways that promote aggressive cancer biology, more attention should be paid by cancer physicians to screening and treating insulin resistance. Several studies have reinforced a link between breast cancer risk and diabetes. Moreover, metformin significantly reduces breast cancer risk, compared to patients who are not using metformin and is independent of diabetes status. As metformin has an association with decreased breast cancer recurrence, as well as potentially improved survival, disparities in insulin resistance between black and white women with breast cancer is important to investigate. It is hypothesized that metformin decreases the development of resistance in breast cancer cells, thereby allowing current chemotherapy agents to work synergistically with metformin. Our objective is to elucidate whether or not metformin is efficacious in improving insulin resistance in black and white women with breast cancer and if racial disparities in breast cancer prognosis can be partially explained by differences in pre-diagnosis insulin resistance which are improved with metformin therapy.

Defining the Role of Management Factors in Outcome Disparity in Pediatric T1D
Description

Type 1 diabetes (T1D), is associated with considerable risk of morbidity and mortality due to chronic hyperglycemia. Despite innovations in management, pediatric patients of African ancestry (AA) have been found to have persistently higher mean blood glucose (MBG) than European ancestry (EA) patients. The investigators hypothesize that an intervention using advanced insulin delivery technology together with home management will sustainably improve MBG to levels comparable to EA patients without increasing hypoglycemia. The investigators will first perform a small "field trial" of the intervention in African American patients having T1D, with 8.5\<HbA1c\<12% aged 10-17 years. The primary intervention approach will use a combination of an advanced hybrid closed loop (AHCL) pump + enhanced home video management conferencing with study CDE nurse coordinator. Information gained in the "field trial" will be used to more specifically tailor the intervention in a randomized trial. In the second part , the investigators will conduct a randomized trial of the study intervention in participants with the same clinical features as the field trial for a six month pilot period. Participants will be randomized into one of four groups. The special intervention group (AHCL+conferencing) group will be compared with a group using patient's current insulin management+followup, vs AHCL+without conferencing, vs patient's standard insulin management+conferencing. The investigators will compare HbA1c, MBG, time in glycemic range, ability to adhere with home management, satisfaction with management procedures between the groups.
