Cellular therapy (CT) involving the transplantation of hematopoietic progenitor cells (HPC) is a treatment modality for both benign and malignant disorders. All autologous products require cryopreservation while allogeneic product cryopreservation became more common during the Coronavirus disease 2019 pandemic. Cells are stored in liquid nitrogen (LN) freezers which can malfunction and products may have to be temporarily stored in a mechanical -80 °C freezer if additional LN freezer space is not available.

To describe the changes in apheresis service practices that occurred during the pandemic, the American Society for Apheresis (ASFA) Apheresis Medicine Attending Physician Subcommittee conducted a survey study.
Study Design And Methods: A 32-question survey was designed and distributed to 400 ASFA physician members on September 7, 2022.
Background And Objectives: Promotion in academic medicine requires evidence of the creation and dissemination of scholarly output, primarily through peer-reviewed publications. Studies demonstrate that scholarly activity and impact are lower for women physicians than for men physicians, especially during the early stages of their academic careers. This report reviewed physicians' academic productivity after passing their Blood Banking/Transfusion Medicine (BBTM) subspecialty exam to determine if gender discrepancies exist.

RCE provided similar leukoreduction to standard therapeutic leukoreduction and could be superior in patients with severe anemia or monocytic leukemias or when requiring rapid treatment.

Blood product inventories are dependent upon the availability of donors, supplies and reagents, and collection staff. During prolonged extreme shortages, blood centers and transfusion services must alter practices to meet the needs of patients.
View Article and Find Full Text PDFBackground: Transfusion services and blood banks in the United States have struggled with staffing shortages for decades. Unfortunately, the COVID-19 pandemic and other factors have exacerbated these challenges to the point of crisis for many. Meanwhile, providing quality patient care continues to demand accurate test results and safe blood products delivered in a timely fashion.

In this study, we report findings from a survey conducted among American Society for Apheresis Physician Committee (ASFA-PC) members to describe the impact of the COVID-19 pandemic on AM education practices.
Study Design And Methods: A voluntary, anonymous, 24-question, institutional review board-approved survey regarding AM teaching during the pandemic was distributed to ASFA-PC members in the United States between December 1, 2020, and December 15, 2020.
Recent advances in managing Sickle Cell Disease (SCD) significantly improved patient survival and quality of life. Disease-modifying drug therapies such as hydroxyurea, L-glutamine, voxelotor, and crizanlizumab reduce pain crises and severe complications. Allogeneic hematopoietic stem cell transplantation using matched-sibling donors is currently the only standard curative option; however, only a small proportion of patients have such donors.

This study characterizes the BB/TM workforce to determine the scholarly productivity in the first 3 to 5 years after obtaining board certification and the impact of job type, job location, and academic rank on scholarly productivity. Academic productivity was assessed among individuals passing the American Board of Pathology BB/TM board exam between 2016 and 2018 using the National Institutes of Health (NIH) Office of Portfolio Analysis tool, iCite.

Gene therapy will soon become the dominant modality for treating of sickle cell disease (SCD). Currently, three technologies are the most promising: expression of transgenic globin genes via a lentiviral vector, controlled mutation of the β-globin control cluster by transgenic CRISPR-based ribonucleoprotein, and suppression of BCL11a mRNA by shRNA. In this review, we discuss the mechanism of each technology and how they correct the SCD pathology at the molecular level.

We performed an inter-laboratory evaluation of the performance of this new assay.
Study Design And Methods: This Biomedical Excellence for Safer Transfusion (BEST) Collaborative multicenter, international study included 15 participants from public cord blood banks (CBBs), CBB-supporting research laboratories, and stem cell laboratories.
Red blood cell (RBC) transfusions are necessary to increase a patient's oxygen carrying capacity. The optimal transfusion trigger remains elusive, but a restrictive transfusion trigger of 7 g/dL has been shown in studies to reduce RBC transfusions without adversely affecting patient outcomes. Patient blood management programs have been shown effective at reducing RBC transfusions.

In this study, we report findings from a survey conducted among attending physician (AP) members of the American Society for Apheresis (ASFA) to elucidate the status of their well-being during the COVID-19 pandemic as well as resources provided or actions taken by their institutions and themselves personally to maintain or improve their well-being.
Study Design And Methods: A 17-question, voluntary, IRB-approved survey regarding well-being was distributed to the ASFA AP members between August 26, 2020 and September 16, 2020.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has led to a major pandemic. While vaccine development moves forward, optimal treatment continues to be explored. Efforts include an ever-expanding number of clinical trials along with newly proposed experimental and off-label investigational therapies; one of which is therapeutic plasma exchange (TPE).

Both diseases are associated with significant morbidity and mortality. Because patients require lifelong follow-up and care, it also poses a serious burden in health services.

The purpose of this study is to develop EPAs specific for the practice of apheresis medicine (AM).
Methods: Members of the American Society for Apheresis Graduate Medical Education subcommittee developed a list of 28 apheresis medical activities linked to Accreditation Council for Graduate Medical Education milestones and competencies in five areas: (a) consultation, (b) clinical care for therapeutic apheresis, (c) clinical care for donor collections, (d) test optimization, and (e) vascular access.
