An Upstream Reparative Justice Framework for Improving Diversity in Radiology.

Health care workforce diversity is vital in combating health disparities. Despite much recent attention to downstream strategies to improve diversity in radiology, such as increased recruitment efforts and holistic application review, workforce diversity has not tangibly improved in recent decades. Yet, little discussion has been devoted to defining the obstacles that might delay, complicate, or altogether prevent persons from groups that have been traditionally marginalized and minoritized from a career in radiology. Refocusing attention to upstream barriers to medical education is vital to develop sustainable workforce diversity efforts in radiology. The purpose of this article is to highlight the varied obstacles students and trainees from historically underrepresented communities may face along the radiology career pathway and to provide concrete corollary programmatic solutions. Using a reparative justice framework, which encourages race- and gender-conscious repair of historical injustices, and the socioecological model, which recognizes an individual's choices are informed by historical and ongoing systems of power, this article advocates for tailored programs to improve justice, equity, diversity, and inclusion in radiology.

Historically Black Schools of Medicine Radiology Residency Programs: Contributions and Lessons Learned.

INTRODUCTION: Black radiologists remain significantly underrepresented in the radiology workforce, despite a 1973 plea by Black radiologists of the National Medical Association to increase training programs for minority radiologists. OBJECTIVE: The authors provide a qualitative narrative that highlights the radiology residency programs of three historically Black schools of medicine (HBSOM) in the U.S., their contributions, and lessons learned from their closure. METHODS: Data from public repositories, interviews, and conversations were conflated to chronicle significant events and establish a timeline during these residency programs' existence. RESULTS: Radiology residencies at Howard University School of Medicine (1945), Meharry Medical College (1949), and Charles R. Drew University of Medicine and Science (1972) were established to train Black doctors to treat communities of color. These programs provided care to underserved and under-resourced areas of the country, where inequitable health care fueled a legacy of poor health outcomes. These radiology residency programs collapsed under the weight of suboptimal funding, strapped capital budgets, attrition of faculty, a declining hospital patient census, and failure to maintain other residency specialty programs.` CONCLUSION: Understanding the history and impact of these programs, and of their closure, can be leveraged to develop strategies to increase the representation of racial and ethnic minorities in radiology. Possible reinstatement, with appropriate allocation of resources and creation of intentional policies to ensure sustained success, merits further investigation and may be a pathway to achieve optimal representation.

Genomic Analyses Identify Novel Molecular Signatures Specific for the Caenorhabditis and other Nematode Taxa Providing Novel Means for Genetic and Biochemical Studies.

The phylum Nematoda encompasses numerous free-living as well as parasitic members, including the widely used animal model Caenorhabditis elegans, with significant impact on human health, agriculture, and environment. In view of the importance of nematodes, it is of much interest to identify novel molecular characteristics that are distinctive features of this phylum, or specific taxonomic groups/clades within it, thereby providing innovative means for diagnostics as well as genetic and biochemical studies. Using genome sequences for 52 available nematodes, a robust phylogenetic tree was constructed based on concatenated sequences of 17 conserved proteins. The branching of species in this tree provides important insights into the evolutionary relationships among the studied nematode species. In parallel, detailed comparative analyses on protein sequences from nematodes (Caenorhabditis) species reported here have identified 52 novel molecular signatures (or synapomorphies) consisting of conserved signature indels (CSIs) in different proteins, which are uniquely shared by the homologs from either all genome-sequenced Caenorhabditis species or a number of higher taxonomic clades of nematodes encompassing this genus. Of these molecular signatures, 39 CSIs in proteins involved in diverse functions are uniquely present in all Caenorhabditis species providing reliable means for distinguishing this group of nematodes in molecular terms. The remainder of the CSIs are specific for a number of higher clades of nematodes and offer important insights into the evolutionary relationships among these species. The structural locations of some of the nematodes-specific CSIs were also mapped in the structural models of the corresponding proteins. All of the studied CSIs are localized within the surface-exposed loops of the proteins suggesting that they may potentially be involved in mediating novel protein-protein or protein-ligand interactions, which are specific for these groups of nematodes. The identified CSIs, due to their exclusivity for the indicated groups, provide reliable means for the identification of species within these nematodes groups in molecular terms. Further, due to the predicted roles of these CSIs in cellular functions, they provide important tools for genetic and biochemical studies in Caenorhabditis and other nematodes.
