Purpose: To investigate the prevalence and type of clinical pharmacy services offered within South Carolina Federally Qualified Health Centers (SC FQHCs) and identify existing implementation barriers.

Methods: This study was a cross-sectional survey of pharmacists or Chief Medical Officers practicing in SC FQHCs. Organizations were identified utilizing the Health Resources and Services Administration (HRSA) database and were contacted to participate in a telephone survey.

Article Synopsis
  • HIV-exposed uninfected (HEU) infants show higher levels of pro-inflammatory biomarkers that continue after birth, potentially influenced by maternal immunity in pregnant women with HIV (PWH).
  • The study analyzed plasma samples from 46 HEU infants and their mothers, comparing results with pregnant women without HIV (PWOH) and their HIV unexposed uninfected (HUU) newborns.
  • Results indicated that both PWH and HEU infants have elevated immune biomarkers, but many of these levels normalized in HEU infants by 6 months, suggesting the short-term effects of maternal inflammation on their immune development.

Human cytomegalovirus (HCMV) encodes four viral Fc-gamma receptors (vFcγRs) that counteract antibody-mediated activation , but their role in infection and pathogenesis is unknown. To examine the function of vFcγRs in animal hosts closely related to humans, we identified and characterized vFcγRs encoded by rhesus CMV (RhCMV). We demonstrate that Rh05, Rh152/151 and Rh173 represent the complete set of RhCMV vFcγRs, each displaying functional similarities to their respective HCMV orthologs with respect to antagonizing host FcγR activation .

Keeping abreast of the antimicrobial stewardship-related articles published each year is challenging. The Southeastern Research Group Endeavor identified antimicrobial stewardship-related, peer-reviewed literature that detailed an actionable intervention during 2022. The top 13 publications were selected using a modified Delphi technique.

Human cytomegalovirus (HCMV) remains the most common congenital infection and infectious complication in immunocompromised patients. The most successful HCMV vaccine to date, an HCMV glycoprotein B (gB) subunit vaccine adjuvanted with MF59, achieved 50% efficacy against primary HCMV infection. A previous study demonstrated that gB/MF59 vaccinees were less frequently infected with HCMV gB genotype strains most similar to the vaccine strain than strains encoding genetically distinct gB genotypes, suggesting strain-specific immunity accounted for the limited efficacy.
