Transfusion Medicine Reviews最新文献

Blood Banking/Transfusion Medicine (BB/TM) specialists oversee all aspects of blood component transfusions and are often involved with apheresis, coagulation, and cellular therapy services as well. 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. One hundred and 28 BB/TM specialists were included in the analysis. The majority of BB/TM specialists work in academia, are located in the Great Lakes and Mid-Atlantic regions, and have a rank of Assistant Professor. Since passing the board exam, 76.5% (98/128) of BB/TM specialists have published papers, with 4.0 (IQR = 1-8) total number of published papers per individual, and 791 total papers amongst the group. The median publications per individual per year since passing boards is 0.9 (IQR = 0.2-2.3) the number of publications per year since passing boards for BB/TM specialists in academia is significantly higher compared to other jobs at 1.33 (IQR, 0.5-2.89, Kruskal-Wallis P = .03) per individual Assistant Professors and Associate Professors (1.3, IQR= 0.4-2.7 and 1.4, IQR = 0.6-3.3, Mann-Whitney test P > .99). BB/TM specialists who passed the board exam between 2016 and 2018 are highly academically productive, especially those working in academia where publications are necessary for promotion. BB/TM physicians are an extensively trained and academically-minded group of practitioners.

Therapeutic apheresis refers to a diversity of procedures in which specific hematologic components (e.g., plasma, erythrocytes, leukocytes, etc.) with pathological associations are removed from circulation (with possible replacement) in order to treat a variety of disease processes. As pharmacologic agents also circulate with these components, their removal is sometimes incidental, or in the scenario of drug toxicity, a therapeutic goal. The corpus of published manuscripts on this subject has grown immensely over the past few decades; however, the breadth of diseases, methods, and drugs that co-exist in this space make it challenging to generate generalizable evidence regarding drug removal via apheresis. This review discusses factors worth considering when interpreting literature-reported data on drug removal by apheresis with examples from several notable studies and highlights topics in need of evidential improvement and growth as our palette of therapeutic agents continues to expand.

In May of 2022, a multinational outbreak of monkeypox was recognized. It expanded rapidly and over the following three-plus months, more than 50,000 cases were reported from 100 countries, largely among gay or bisexual men. The causative agent is a poxvirus, related to smallpox and vaccinia viruses. Available information implies that the virus might be transfusion-transmissible, although no cases had been reported by late August, 2022. Current data are reviewed, and the potential impacts of transfusion transmission are discussed, along with potential interventions.

Therapeutic plasma exchange (TPE) has traditionally been used to selectively remove pathologic contents including autoantibodies, abnormal proteins, immune complexes, or toxins from a patient's plasma. In addition to the removal of molecular contributors to disease, fluid replacement and infusion of beneficial plasma constituents including albumin can be tapered based on the pathophysiologic mechanisms of the offending disease. This treatment modality has shown efficacy in symptomatic relief and slowing of disease progression for various neurologic, immunologic, and hematologic diseases. This review outlines the rationale for TPE in the treatment of Alzheimer's Disease (AD) through a potential mechanism leveraging the concentration gradient of amyloid β peptides and the infusion of albumin, and critically reviews the clinical evidence for treatment of AD using TPE and albumin replacement. This review also highlights potential sources of bias that must be considered in conjunction with the evidence of efficacy for the use of TPE in AD.
