Achieving health equity requires data systems that recognize and reflect provider diversity. The National Provider Identifier (NPI) system underpins United States health care administration, yet its gender data standards remain outdated, conflating sex and gender and lacking inclusive options. These deficiencies undermine research, equity initiatives, and the visibility of transgender and nonbinary providers.

Mixed autoimmune hemolytic anemia (AIHA) is a rare and clinically complex hematologic disorder defined by the simultaneous presence of both warm and cold autoantibodies, resulting in severe and often treatment-resistant hemolysis. Due to variability in diagnostic criteria and limited data, a comprehensive understanding of its epidemiology, clinical characteristics, and management remains incomplete. To address these gaps, we performed a systematic literature review employing stringent diagnostic criteria to evaluate epidemiologic patterns, clinical features, and therapeutic outcomes.

In the United States and other high-income countries, blood donation primarily relies on anonymous, voluntary donors. However, directed blood donation-where people donate for a specific recipient-has resurged, particularly due to misinformation surrounding COVID-19 vaccination. Requests for "nonvaccinated" blood, driven by misconceptions about vaccine safety, have led to legislative attempts to mandate compliance.

Immune thrombotic thrombocytopenic purpura (iTTP) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and microvascular occlusion secondary to acquired ADAMTS13 deficiency. Contemporary data regarding iTTP treatment practices in the US, including the use of caplacizumab, are lacking. We aimed to characterize the demographics and therapies, including medications and apheresis practices, in patients with iTTP in the US.

Disparities persist throughout medicine, including among conference speakership invitations. The National Institutes of Health have highlighted the importance of diversity at academic conferences. We assessed the gender composition of speakers at the American Society for Apheresis (ASFA) annual meeting.

Introduction/background: Platelet membrane glycoproteins (GPs) serve several functions, the most significant of which is their role in primary hemostasis. Among these, GP IIb/IIIa is the primary fibrinogen receptor and is essential for platelet aggregation. Its deficiency or dysfunction impairs platelet aggregation, leading to Glanzmann thrombasthenia, a rare autosomal recessive bleeding disorder.

Article processing charges are increasingly being levied on authors via publication fees to provide open access to readers. These charges may impose challenges to early career physicians seeking to publish research but pathology journal article processing charges have not been investigated to date. We aimed to quantify pathology journal article processing charges and investigate the potential associated factors.

Article Synopsis
  • The ASFA Attending Physician Subcommittee reviewed 2023 apheresis literature and selected the top 10 seminal articles in the field.
  • They focused on four main topics: donor apheresis, therapeutic apheresis, education, and cellular therapy, using PubMed and OVID for research.
  • The chosen articles met key criteria such as novel findings, practice-changing results, and relevance to current clinical practice, while excluding case reports, reviews, and meta-analyses.

Article Synopsis
  • Hemolytic disease of the fetus and newborn (HDFN) results from maternal antibodies attacking the fetal red blood cells, but current clinical monitoring practices for it are inconsistent across institutions.
  • A survey of 103 US institutions revealed that while most conduct maternal antibody testing, methods and follow-up practices vary significantly, with only 27% employing cell-free fetal DNA testing to assess fetal risk.
  • The findings indicate a need for standardization in laboratory testing and improved cooperation between blood banks and maternal-fetal medicine services to better manage HDFN risk.

Background: Normothermic regional perfusion (NRP) and normothermic machine perfusion (NMP) are organ procurement and transport techniques that can improve organ quality, facilitate longer transport, and reduce postoperative complications, increasing organ availability and improving outcomes. NRP and NMP often require allogeneic red blood cells (RBCs). Our academic transfusion service began providing RBCs to support NRP and NMP for adult heart transplant (HT), orthotopic liver transplant (OLT), and multiorgan transplant (MOT) in August 2020.

Prior studies have suggested that immune thrombotic thrombocytopenic purpura (iTTP) may display seasonal variation; however, methodologic limitations and sample sizes have diminished the ability to perform a rigorous assessment. This 5-year retrospective study assessed the epidemiology of iTTP and determined whether it displays a seasonal pattern. Patients with both initial and relapsed iTTP (defined as a disintegrin and metalloprotease with thrombospondin type motifs 13 activity <10%) from 24 tertiary centers in Australia, Canada, France, Greece, Italy, Spain, and the US were included.

The actual risk of providing RhD-positive units to RhD-negative recipients remains debatable. There is no standard of care in the United States (US) to guide transfusion decisions regarding RhD type for patients with an unknown blood type, except for women of childbearing age and neonates. The risk of alloantibody formation by an RhD-negative patient exposed to RhD-positive blood is reported to be from 3% to 70%.

Article Synopsis
  • A study evaluated apheresis practices in the US through a national survey involving 22 academic medical institutions to identify trends and challenges.
  • The survey revealed that therapeutic plasma exchange (TPE) is the most common procedure, with issues in staffing exacerbated by COVID-19 affecting service delivery.
  • Findings emphasized the importance of apheresis in cellular therapies and the need for innovative staffing solutions in the context of ongoing medical advancements and challenges.

Hematopoietic stem cell transplantation (HSCT) is a cornerstone of modern medical practice, and can only be performed safely and effectively with appropriate transfusion medicine support. Patients undergoing HSCT often develop therapy-related cytopenia, necessitating differing blood product requirements in the pre-, peri-, and post-transplant periods. Moreover, ensuring optimal management for patients alloimmunized to human leukocyte antigens (HLA) and/or red blood cell (RBC) antigens, as well as for patients receiving ABO-incompatible transplants, requires close collaboration with transfusion medicine and blood bank professionals.

Background: The COVID-19 pandemic affected healthcare delivery across all specialties including apheresis. 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: Current Association for the Advancement of Blood & Biotherapies (AABB) standards require transfusion services to have a policy on Rh immune globulin (RhIG) immunoprophylaxis for when RhD-negative patients are exposed to RhD-positive red cells. This is a survey of AABB-accredited transfusion services in the United States (US) regarding institutional policies and practices on RhIG immunoprophylaxis after RhD-negative patients receive RhD-positive (i.e.

Objectives: Gender equity studies have shown that women are underrepresented in journal editor in chief positions, which confer major professional opportunities and influence. We sought to systematically investigate editor in chief gender and journal attributes within pathology.

Methods: We constructed a journal data set using the Scimago Journal & Country Rank and Clarivate Journal Citation Reports databases.
