Introduction: Granular cell tumors (GCTs) are of neuroectodermal origin and account for 0.5% of soft tissue tumors. They are most prevalent in African-Americans in the fourth to sixth decades, with a predilection for the head and neck regions. GCTs usually resemble more common lesions and hence are difficult to diagnose preoperatively. The tumor is readily identified on needle biopsy. Although usually benign with a malignancy rate of only 2-3%, the malignant form has a reported 3-yr mortality of 60%...

Compared with all other racial and ethnic groups in the U.S., African Americans are disproportionally affected by lung cancer, both in terms of incidence and survival. It is likely that smoking, as the main etiological factor associated with lung cancer, contributes to these disparities, but the precise mechanism is still unclear. This paper seeks to explore the history of lung cancer disparities and review to the literature regarding the various factors that contribute to them.

INTRODUCTION: Cardiovascular complications represent the leading cause of morbidity and mortality in patients with Marfan syndrome. Here, we describe a unique case where a total artificial heart was implanted in a young Marfan syndrome woman. METHODS: A 22-year-old postpartum African American female with Marfan syndrome developed multiple severe valve dysfunction and biventricular failure that was refractory to medical management. She previously had a Bentall procedure for Type A aortic dissection and repair of a Type B dissection...

Ethnic/racial self-labeling represents one's knowledge of and preference for ethnic/racial group membership, which is related to, but distinguishable from, ethnic/racial identity. This study examined the development of ethnic/racial self-labeling over time by including the concept of elaboration among a diverse sample of 297 adolescents (Time 1 mean age 14.75, 67% female, 37.4% Asian or Asian American, 10.4% Black, African American, or West Indian, 23.2% Hispanic or Latinx, 24.2% White, 4.4% other). Growth mixture modeling revealed two distinct patterns-low and high self-labeling elaboration from freshman to sophomore year of high school...

Context: Abnormal fatty acid (FA) metabolism contributes to diabetes and cardiovascular disease. The FA receptor CD36 has been linked to risk of metabolic syndrome. In rodents CD36 regulates various aspects of fat metabolism but whether it has similar actions in humans is unknown. We examined impact of a coding single-nucleotide polymorphism in CD36 on post-prandial hormone and bile acid (BA) responses. Objective: To examine if the minor allele (G) of coding CD36 variant rs3211938 (G/T) which reduces CD36 level by approximately 50% influences hormonal responses to a high-fat meal (HFM)...

Background: A high fructose intake has been shown to be associated with increased serum urate concentration, whereas ascorbate (vitamin C) may lower serum urate by competing with urate for renal reabsorption. Objective: We assessed the combined association, as the fructose:vitamin C intake ratio, and the separate associations of dietary fructose and vitamin C intakes on prevalent hyperuricemia. Methods: We conducted cross-sectional analyses of dietary intakes of fructose and vitamin C and serum urate concentrations among Jackson Heart Study participants, a cohort of African Americans in Jackson, Mississippi, aged 21-91 y...

Nearly half of African-American women have hypertension, which increases their risk for cardiovascular disease and stroke. A plethora of consumer health information products and services exist to inform people with hypertension and to promote self-management among them. Promotion of information sharing by African-American women represents a promising, culturally-applicable strategy for consumer health information services focused on hypertension self-management. Yet, how African-American women share hypertension information with others is unclear...

Breast cancer, a heterogeneous disease with variable pathophysiology and biology, is classified into four major subtypes. While hormonal- and antibody-targeted therapies are effective in the patients with luminal and HER-2 subtypes, the patients with triple-negative breast cancer (TNBC) subtype do not benefit from these therapies. The incidence rates of TNBC subtype are higher in African-American women, and the evidence indicates that these women have worse prognosis compared to women of European descent. The reasons for this disparity remain unclear but are often attributed to TNBC biology...

Importance: The Colorado Retinopathy of Prematurity (CO-ROP) model uses birth weight, gestational age, and weight gain at the first month of life (WG-28) to predict risk of severe retinopathy of prematurity (ROP). In previous validation studies, the model performed very well, predicting virtually all cases of severe ROP and potentially reducing the number of infants who need ROP examinations, warranting validation in a larger, more diverse population. Objective: To validate the performance of the CO-ROP model in a large multicenter cohort...

The purpose of the study was to examine the factor structure, measurement invariance, and psychometric properties of a commonly used measure of perceived career barriers (The Perception of Barriers Scale; Luzzo & McWhirter, 2001) with racially diverse college women. The results supported a 9-factor structure for the Perception of Barriers Scale; configural, metric, and scalar invariance for the 9-factors were found with Asian, African American, Latina, and White college women. All groups of women of color reported higher career barriers due to racism and higher educational barriers due to racial discrimination than White women...

When Donald Trump became president of the United States, I discovered that my clients who identified as Black saw me as a White clinician. With that came a host of nefarious attributions. To preserve therapeutic efficacy, and the genuine relationships with people about whom I cared, I had to distinguish myself from the president; thus, I learned not only how it feels to be seen through the bias of skin color but what I needed to do to identify as a person rather than a White person. "Welcome to my world," said one African American client...

Prior studies identified HLA class-II and 57 additional loci as contributors to genetic susceptibility for type 1 diabetes (T1D). We hypothesized that race and/or ethnicity would be contextually important for evaluating genetic risk markers previously identified from Caucasian/European cohorts. We determined the capacity for a combined genetic risk score (GRS) to discriminate disease-risk subgroups in a racially and ethnically diverse cohort from the southeastern U.S. including 637 T1D patients, 46 at-risk relatives having two or more T1D-related autoantibodies (≥2AAb+ ), 790 first-degree relatives (≤1AAb+ ), 68 second-degree relatives (≤1 AAb+ ), and 405 controls...

INTRODUCTION: Low-income caregiver perspectives on asthma management are understudied but may illuminate strategies to improve care delivery and child outcomes. METHOD: Purposive sampling methods were used to recruit 15 caregivers of children with frequent asthma emergency department visits. Interviews explored how poverty and stress affect asthma management. Grounded theory coding techniques were used to analyze the data. RESULTS: Participants were the biological mother (100%) and were poor (75% had mean annual income ≤ $30,000)...

The Diabetes Prevention Program (DPP) landmark randomized trial demonstrated that participants with prediabetes could reduce their risk for type 2 diabetes by 58% if they achieved 5%-7% weight loss through healthy eating and increasing physical activity. The National DPP (NDPP) is a group intervention based on the DPP and has been widely disseminated by the Centers for Disease Control and Prevention (CDC) and many healthcare institutions. While data show that the program is effective in diverse populations, enrollment among men from low-income and minority communities is low...

African Americans are perceived to be least likely of all racial and ethnic groups to prepare for the end of life. However, verbal plans for the end of life are of particular importance to this population and may help understand why they are less likely to possess a formal end-of-life care planning document. The purpose of this study was to determine the number of formal and/or informal end-of-life care plans that existed among a convenience sample of African American older adults with dementia. For this descriptive study, data were collected from African American family caregivers (N = 65) of older adults with dementia...

BACKGROUND: Several studies have been performed to evaluate surrogate markers of long-term allograft function in renal transplant recipients. These include serum creatinine, estimated glomerular filtration rate (eGFR), slope of eGFR, and more recently eGFR variability. The aim of this study was to measure eGFR slope while assessing the variability of this slope and if high variability occurring at any time post-transplant was predictive of poorer long-term outcomes in a large cohort of kidney transplant recipients...

Disparities in hepatocellular carcinoma (HCC) incidence and survival have been observed between ethnic groups including African-Americans (AA) and European-Americans (EA). The evaluation of the changes in the levels of metabolites in samples stratified by race could provide a snapshot of ethnically diverse disease related pathways and identify reliable biomarkers. In this study, we considered AA and EA to investigate metabolites that may be associated with HCC in a race-specific manner. The levels of 46 metabolites in plasma samples, collected from patients recruited at MedStar Georgetown University Hospital, were analyzed by Agilent GC-qMS in selected ion monitoring (SIM) mode...

OBJECTIVE: School readiness by kindergarten entry is associated with increased high school graduation, decreased juvenile arrest, and better long-term health. Inadequate early childhood learning (ECL) disproportionately affects low-income children. Pediatricians have near-universal access to children younger than 5 years but remain an underused ECL resource. This study examined caregivers' perceptions of ECL, the role of the pediatrician and pediatric office, and the use of community-based ECL resources among diverse, low-income caregivers whose children were not enrolled in preschool...

PURPOSE: Leisure-time physical activity (LTPA) is a well-established modifiable lifestyle determinant for multiple cardio-metabolic outcomes. However, current understanding of the genetic architecture that may determine LTPA remains very limited. Therefore, we aimed to examine the role of genetic factors in affecting LTPA, which has yet to be investigated comprehensively and in-depth. METHODS: We conducted a genome-wide analysis using 1000 Genomes Project imputed data from the Women's Health Initiative (n=11,865), the Jackson Heart Study (n=3,015) and the Framingham Heart Study (n=7,339)...
