Current advances in transfusion medicine 2020: A critical review of selected topics by the AABB Clinical Transfusion Medicine Committee.

BACKGROUND: The AABB Clinical Transfusion Medicine Committee (CTMC) compiles an annual synopsis of the published literature covering important developments in the field of transfusion medicine (TM), which has been made available as a manuscript published in Transfusion since 2018. METHODS: CTMC committee members reviewed original manuscripts including TM-related topics published electronically (ahead) or in print from December 2019 to December 2020. The selection of topics and manuscripts was discussed at committee meetings and chosen based on relevance and originality. Next, committee members worked in pairs to create a synopsis of each topic, which was then reviewed by two additional committee members. The first and senior authors of this manuscript assembled the final manuscript. Although this synopsis is extensive, it is not exhaustive, and some papers may have been excluded or missed. RESULTS: The following topics are included: COVID-19 effects on the blood supply and regulatory landscape, COVID convalescent plasma, adult transfusion practices, whole blood, molecular immunohematology, pediatric TM, cellular therapy, and apheresis medicine. CONCLUSIONS: This synopsis provides easy access to relevant topics and may be useful as an educational tool.

The impact of COVID-19 on academic productivity by female physicians and researchers in transfusion medicine.

BACKGROUND: Several studies have highlighted the disparities in gender equity that exist in different medical specialties. The COVID-19 pandemic has further heightened the inequity faced by female physicians as they are challenged by increasing household and childcare duties in addition to their professional responsibilities. Given these hurdles, fewer women than men have published in various medical disciplines. In this brief report, we wanted to determine the impact of the COVID-19 pandemic on the academic output of female physicians and researchers in transfusion medicine. STUDY DESIGN AND METHODS: We compared all articles in four transfusion medicine journals published from January 1 to July 31, 2019 with the same time period in 2020. Overall, 1024 articles were reviewed for whether they included women as first or senior authors. RESULTS: Overall, women were first authors in 45.9% (n = 458) of all publications and senior authors in 35% (n = 356) of all publications. There was a statistically significant decrease in the percentage of women as first authors between 2019 (49.1%) and 2020 (42.7%) (p = .04). There was no significant change in the percentage of women as senior authors between 2019 (35.4%) and 2020 (35.5%) (p = 0.99). CONCLUSIONS: Similar to other medical specialties, the COVID-19 pandemic has further increased the disparities faced by female researchers in transfusion medicine as evidenced by a decrease in publications with women as first authors.

Hospital-Based Donor Recruitment and Predonation Serologic Testing for COVID-19 Convalescent Plasma.

OBJECTIVES: Serologic testing for antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in potential donors of coronavirus disease 2019 (COVID-19) convalescent plasma (CCP) may not be performed until after blood donation. A hospital-based recruitment program for CCP may be an efficient way to identify potential donors prospectively. METHODS: Patients who recovered from known or suspected COVID-19 were identified and recruited through medical record searches and public appeals in March and April 2020. Participants were screened with a modified donor history questionnaire and, if eligible, were asked for consent and tested for SARS-CoV-2 antibodies (IgG and IgM). Participants positive for SARS-CoV-2 IgG were referred for CCP collection. RESULTS: Of 179 patients screened, 128 completed serologic testing and 89 were referred for CCP donation. IgG antibodies to SARS-CoV-2 were detected in 23 of 51 participants with suspected COVID-19 and 66 of 77 participants with self-reported COVID-19 confirmed by polymerase chain reaction (PCR). The anti-SARS-CoV-2 IgG level met the US Food and Drug Administration criteria for "high-titer" CCP in 39% of participants confirmed by PCR, as measured by the Ortho VITROS IgG assay. A wide range of SARS-CoV-2 IgG levels were observed. CONCLUSIONS: A hospital-based CCP donor recruitment program can prospectively identify potential CCP donors. Variability in SARS-CoV-2 IgG levels has implications for the selection of CCP units for transfusion.
