Fourty-four unrelated North American Blacks and one Black family were tested for B-cell specific antigens with 7th International Workshop antisera. DR specificities were clearly defined in this group, but were generally less frequent than reported for Black Americans in the 7th Workshop report and were most similar in frequency to those reported for African Blacks. Five new B-cell specificities (DuB40-43, 45) were identified. In contradistinction to Caucasians, Black Americans type for HLA-D with homozygous typing cells failed to exhibit strong linkage disequilibrium between D and DR types.

Although pandemic-era telemedicine flexibilities may have preserved access to care, concerns remain that telemedicine may have been inequitably distributed among older adults, especially those with mild cognitive impairment or dementia (MCID). As telemedicine flexibilities are set to fully expire on December 31, 2024, we aimed to examine pandemic-era and future-intended telemedicine use among older Americans to help inform post-pandemic telemedicine policy design. We hypothesized that telemedicine would be disproportionately underutilized among older adults with MCID or with racial and ethnic minority status.

Background: In Alabama, the undiagnosed HIV rate is over 20%; youth and young adults, particularly those who identify as sexual and gender minority individuals, are at elevated risk for HIV acquisition and are the only demographic group in the United States with rising rates of new infections. Adolescence is a period marked by exploration, risk taking, and learning, making comprehensive sexual health education a high-priority prevention strategy for HIV and sexually transmitted infections. However, in Alabama, school-based sexual health and HIV prevention education is strictly regulated and does not address the unique needs of sexual and gender minority teenagers.

Objective: The objective of this study was to assess the associations of WIC participant, caregiver, and household characteristics with WIC food benefit redemption.
This study explores the process of becoming-scientist-with, a dynamic and relational concept that redefines science identity development as a nonlinear, evolving journey. Focused on a Black male student, Travis, the study examines how his science identity was shaped through entanglements with various material and discursive forces across multiple science, technology, engineering, math, and medicine (STEMM) learning spaces. Becoming-scientist-with is conceptualized as a continual negotiation of identity within these environments, emphasizing the roles of power, systemic racism, and institutional practices in shaping students' experiences.
