Sickle cell trait (SCT) has been associated with alterations in various immune-related laboratory parameters including lower circulating lymphocyte counts. To further characterize the impact of SCT on the immune system, we performed flow cytometry of monocyte and lymphocyte immune cell subsets from peripheral blood mononuclear cells collected in a large, community-based cohort of SCT-positive (n = 68) and SCT-negative (n = 959) Black adults. SCT was significantly associated with lower proportions of CD8 and CD4 T cell subsets that include senescent-like markers of repeated immune system challenges.

The rapid advances in genomics over the last decade have come to fruition amid intense public discussions of justice in medicine and health care. While much emphasis has been placed on increasing diversity in genomics research participation, an overly narrow focus on recruitment eschews recognition of the disparities in health care that will ultimately shape access to the benefits of genomic medicine. In this essay, we suggest that achieving a just genomics, both now and in the future, requires an explicit ELSI of translation-normative and pragmatic scholarship that embraces the interconnectedness of research and clinical care and centers the obligations of researchers, institutions, and funders to mitigate inequities throughout the translational pipeline.

Unlabelled: Increasing demand for poultry has spurred poultry production in low- and middle-income countries like Mozambique. Poultry may be an important source of foodborne, antimicrobial-resistant bacteria to consumers in settings with limited water, sanitation, and hygiene infrastructure. The Chicken Exposures and Enteric Pathogens in Children Exposed through Environmental Pathways (ChEEP ChEEP) study was conducted in Maputo City, Mozambique from 2019 to 2021 to quantify enteric pathogen exposures along the supply chain for commercial and local (i.

Somatic mosaicism is an important cause of disease, but mosaic and somatic variants are often challenging to detect because they exist in only a fraction of cells. To address the need for benchmarking subclonal variants in normal cell populations, we developed a benchmark containing mosaic variants in the Genome in a Bottle Consortium (GIAB) HG002 reference material DNA from a large batch of a normal lymphoblastoid cell line. First, we used a somatic variant caller with high coverage (300x) Illumina whole genome sequencing data from the Ashkenazi Jewish trio to detect variants in HG002 not detected in at least 5% of cells from the combined parental data.
