Background: The Assessing Donor Variability and New Concepts in Eligibility (ADVANCE) study was a multicenter cross-organizational collaboration to collect data to inform possible changes in blood donor selection criteria for men who have sex with men. Multiple recruitment approaches were used, and these may be applicable to current efforts in LGBTQ+ community engagement to recruit new blood donors.

Methods: Fieldwork for ADVANCE was a partnership between blood collection organizations (BCOs) and LGBTQ+ community organizations.

Background: For many years, there has been concern about the risk of transmission of classic forms of Creutzfeldt-Jakob disease (CJD) by blood transfusion, particularly after the recognition of such transmission of variant CJD (vCJD). We report on a 28-year lookback study of recipients of blood from donors who subsequently developed CJD.

Methods: Patients with diagnosed CJD and a history of blood donation were identified.

Introduction: The International Association of Dental Traumatology (IADT) guidelines include the use of decoronation for the management of complex crown-root fractures but do not outline how this technique is best employed. The aim of this review is to reach a consensus in the management of the root canal system in decoronated permanent teeth undergoing root submergence and to determine whether this has an impact on the success and survival of the retained root.

Materials And Methods: Search included databases MEDLINE via Ebsco, EMBASE via Ovid, Web of Science via Clarivate, PubMed via PubMed.

Article Synopsis
  • The study focused on assessing HIV risk behaviors in men who have sex with men (MSM) to evaluate their eligibility for blood donation based on individual risk assessments.
  • Conducted in eight U.S. cities, the research involved surveys and blood tests for HIV and tenofovir, a PrEP drug, among sexually active MSM aged 18-39.
  • Results showed that about 50% of the participants were not using PrEP, and many reported lower-risk sexual behaviors, suggesting that a significant portion could be eligible to donate blood based on their risk profiles.

We evaluated antibodies to the nucleocapsid protein of SARS-CoV-2 in a large cohort of blood donors in the United States who were recently infected with the virus. Antibodies to the nucleocapsid protein of SARS-CoV-2 indicate previous infection but are subject to waning, potentially affecting epidemiologic studies. We longitudinally evaluated a cohort of 19,323 blood donors who had evidence of recent infection by using a widely available serologic test to determine the dynamics of such waning.

Background: Early in the SARS-CoV-2 pandemic, many blood collection organizations (BCOs) were asked to collect and distribute COVID-19 convalescent plasma (CCP) as a potential treatment for this new virus and resulting disease. However, recruiting CCP donors presented unique challenges for BCOs, as there were few recovered patients at this time, and like the general population, most potential CCP donors had no blood donation experience. Thus, many CCP donors were new donors, and their donation motivations were unknown.

Background: Iron supplementation (IS) improves blood donors' iron stores and allows more frequent blood donation. Understanding the accuracy of self-reported IS is helpful for potential application of IS practices to donor eligibility or donation intervals.

Methods: Successful whole blood and red cell apheresis donors completed a survey at donation on the use of select dietary supplements.

Background And Objectives: Chagas disease, caused by Trypanosoma cruzi, is endemic to Mexico, Central and South America. While initially limited to the Americas, emigration of infected persons triggered geographically broader blood safety challenges. To mitigate transfusion-transmitted Chagas (TTC), transfusion services implemented approaches including risk factor questions and serologic testing.

Background: Severe blood donor adverse events are rare, but due to their rarity studying them can be difficult. To get an accurate estimate of their frequency and rate in the donor population it may be necessary to combine donation data across countries.

Study Design And Methods: International blood collection organizations (BCOs) provided data on rare/severe donor reactions as well as denominator information for their donor populations from 2015 to 2017.

Background: With coronavirus disease 2019 (COVID-19) convalescent plasma (CCP) offering an early treatment option for COVID-19, blood collectors needed to quickly overcome obstacles to recruiting and qualifying eligible donors. We provide attributes of CCP donors and products and compare to standard donors and products.

Study Design And Methods: Information on CCP donors was gathered from the American Red Cross qualification website through product collection.

Background And Objectives: Written materials are commonly used for blood donor education. While pre-donation materials are largely standardized across US blood collectors, the post-donation instruction sheet (PDIS) is variable and few have been evaluated to assess their effectiveness in conveying information as reflected by donors' attention, understanding and recall.

Methods: An online survey was sent to two independent randomly selected samples of repeat donors, before and after implementation of the enhanced PDIS.

Article Synopsis
  • Babesiosis, caused by the parasite Babesia microti, is a serious zoonotic infection transmitted mainly by ticks, with healthy people often being asymptomatic and unaware of their infection.
  • A study from 2004 to 2015 in New York identified 3,799 cases of babesiosis, with 55 (1.4%) linked to blood transfusions, and showed that both community-acquired and transfusion-transmitted babesiosis (TTB) cases significantly increased over the 12-year period.
  • The findings suggest a correlation between the rising incidence of TTB and community-acquired babesiosis, highlighting the need for better surveillance of ticks and cases to mitigate the risk of transmission.

Background: Transfusion transmission of human prion diseases has been observed for variant Creutzfeldt-Jakob disease (vCJD), but not for the classic forms of prion disease (CJD: sporadic, genetic, and iatrogenic). Although the presence of prions or misfolded prion proteins in blood has been documented in some patients with the most common form of CJD, sporadic CJD, no transfusion-transmitted cases of CJD have been recognized. Since 1995, the American Red Cross has conducted a lookback study of the recipients of blood products from donors who develop CJD to assess the risk of blood-borne CJD transmission in the United States.

Article Synopsis
  • HIV prevalence and incidence among blood donors in the Southeastern US were studied from 2009 to 2014, revealing an overall prevalence of 8.3 per 100,000 donations and a decrease in incidence from 7.1 to 3.5 per 100,000 person-years.
  • Among 236 HIV-positive donors, the most common risk factor for male incident donors was men who have sex with men; female donors did not report a predominant behavior.
  • Despite higher HIV rates in this region compared to others in the US, the residual risk of HIV transmission through blood donations is low, decreasing from 1 in 562,000 to 1 in 1,100,000, highlighting the importance of continuous
