Abstract
OBJECTIVES Monocyte distribution width (MDW) is a new biomarker used as an early indicator of sepsis (ESId). It is often aids in the identification of patients who may develop sepsis. This study aims to establish the MDW reference interval (RI) within the healthy population of blood donors using EDTA-K2 as anticoagulant. Many hospitals use this biomarker as a means of identifying patients who present to the hospital with sepsis. METHODS A total of 274 samples obtained from healthy donors were analyzed. MDW measurements were taken within 2 h post-extraction. The RI was estimated using various statistical methodologies, including the recommended CLSI EP28-A3c guideline, non-parametric and robust methods, along with the Harrell-Davis bootstrap method applied to the entire sample. RESULTS The RI estimated through non-parametric method was 14.77 CI90 % (14.36-14.97)-21.13 CI90 % (20.89-21.68); RI using the robust method was 15.64-19.05 and RI using the Harrell-Davis bootstrap method was 14.73 CI90 % (14.53-14.92)-21.14 CI90 % (20.88-21.40). CONCLUSIONS Based on clinical applicability, we recommend utilizing the RI derived from the non-parametric method, aligning with the CLSI recommendations. Furthermore, we consider that our results can be taken as a reference in other laboratories that serve a population similar to our study cohort.

Abstract
BACKGROUND Despite being the largest racial/ethnic minority group in the United States, Hispanic/Latinos (H/L) are significantly underrepresented among blood donors. A lack of proximal blood donation opportunities may be one factor contributing to these disparities. However, few studies have investigated this possibility. STUDY DESIGN AND METHODS Proprietary data on mobile blood collections in Maricopa County, Arizona, were gathered for the period of January 01, 2022 to April 30, 2022 and paired with census tract information using ArcGIS. Maricopa County encompasses the city of Phoenix with a total population of approximately 4.5 million people, including 1.5 million H/L residents. Blood drive count was regressed on H/L ethnic density and total population, and model estimates were exponentiated to obtain odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS During the specified period, approximately 27,000 red blood cell units were collected through mobile drives. Consistent with expectations, when controlling for total neighborhood population, each 10% increase in H/L ethnic density lowered the odds of having a blood drive in the corresponding neighborhood by 12% (OR = 0.88, 95% CI (0.83, 0.92), p < .001). DISCUSSION These findings provide initial evidence of fewer proximal donation opportunities in areas with greater H/L population density which may contribute to H/L underrepresentation in blood donation and the need for more inclusive collection efforts. Improved access to blood collection is modifiable and could help to increase the overall blood supply, enhance the ability to successfully match specific blood antigen needs of an increasingly diverse population, and bring about a more resilient blood system.

Abstract
BACKGROUND AND OBJECTIVES Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serosurveys are typically analysed by applying a fixed threshold for seropositivity ('conventional approach'). However, this approach underestimates the seroprevalence of anti-nucleocapsid (N) in vaccinated individuals-who often exhibit a difficult-to-detect anti-N response. This limitation is compounded by delays between the onset of infection and sample collection. To address this issue, we compared the performance of four immunoassays using a new analytical approach ('ratio-based approach'), which determines seropositivity based on an increase in anti-N levels. MATERIALS AND METHODS Two groups of plasma donors and four immunoassays (Elecsys total anti-N, VITROS total anti-N, Architect anti-N Immunoglobulin G (IgG) and in-house total anti-N) were evaluated. First-group donors (N = 145) had one positive SARS-CoV-2 polymerase chain reaction (PCR) test result and had made two plasma donations, including one before and one after the PCR test (median = 27 days post-PCR). Second-group donors (N = 100) had made two plasma donations early in the Omicron wave. RESULTS Among first-group donors (97.9% vaccinated), sensitivity estimates ranged from 60.0% to 89.0% with the conventional approach, compared with 94.5% to 98.6% with the ratio-based approach. Among second-group donors, Fleiss's κ ranged from 0.56 to 0.83 with the conventional approach, compared with 0.90 to 1.00 with the ratio-based approach. CONCLUSION With the conventional approach, the sensitivity of four immunoassays-measured in a predominantly vaccinated population based on samples collected ~1 month after a positive test result-fell below regulatory agencies requirement of ≥95%. The ratio-based approach significantly improved the sensitivities and qualitative agreement among immunoassays, to the point where all would meet this requirement.

Abstract
OBJECTIVES To evaluate the association between transfusion-transmitted infections (TTIs) and ABO, Rh-D, and Kell blood systems among blood donors. METHODS This was a retrospective study of 10,095 donors who visited the Blood Bank at Asir Hospital, Abha, Saudi Arabia. Data including demographic information, ABO, Rh-D, and Kell blood groups, and serological and molecular test results of TTIs (the TTIs were obtained from each donor's records). Chi-squared and Fisher's exact tests were employed to establish possible associations between blood groups and TTIs. RESULTS The prevalence rate of TTIs among donors was 6.3%, with HBcAb (70%) being the most prevalent biomarker among positive donors. Donors with the O blood group were at a higher risk of contracting TTIs. Significant associations were observed between HIV and blood group A (χ2=6.30, p=0.01), HBsAg and group AB (χ2=17.3193, p=0.00003), malaria and group A (χ2=5.0567, p=0.02), and HBV-DNA and group AB (χ2=12.3163, p=0.0004). Also, Kell blood group was significantly associated with HIV (χ2=14.5, p=0.0001), HBcAb (χ2=78.51, p<0.0001), and syphilis (χ2=25.225, p<0.00001). CONCLUSION ABO and Kell blood groups are associated with TTI markers. These findings highlight the need for improved strategies and approaches in screening and managing blood donations to minimize the risk of TTIs.

Abstract
INTRODUCTION Sanquin donor medicine department is informed when donations or their components are rejected. This can occur isolated or frequently. It is undesirable because the donations cannot be used and there may be an underlying medical cause. Based on regional approaches, a uniform procedure was developed. METHODS Information about whole blood, plasma- plateletpheresis donations from which one or more components were rejected for filtration time (>2 h), hemolysis or clots were extracted from blood bank information system. After rejection of two successive components or donations or total ≥3 the donor is contacted. Depending on the medical history and investigation by the family doctor, the donor carrier is re-evaluated. We looked for the causes of the discarded products and performed a survey among blood services regarding polices with discarded products. RESULTS One or more components from 1742 of about 2.2 million successful donations (0.08%) were rejected. The highest percentage of rejection was seen in plateletpheresis (1.5%), all for clots. No underlying medical causes were found. 24 whole blood donors were found to have sickle cell trait (SCT) and were permanently deferred. The policies for follow-up after discarded products or acceptance of SCT donors vary between the 16 blood banks. Six organizations do not follow-up donors and seven accept SCT for blood or plasma donation. CONCLUSION Informing donors with repeated discarded products avoids the non-use of donations. Causes of repeated discarded products can be found by follow-up of donors. The results of the survey indicate a large discrepancy in policies applied worldwide.

Abstract
Xenotransplantation offers the potential to meet the critical need for heart and lung transplantation presently constrained by the current human donor organ supply. Much was learned over the past decades regarding gene editing to prevent the immune activation and inflammation that cause early organ injury, and strategies for maintenance of immunosuppression to promote longer-term xenograft survival. However, many scientific questions remain regarding further requirements for genetic modification of donor organs, appropriate contexts for xenotransplantation research (including nonhuman primates, recently deceased humans, and living human recipients), and risk of xenozoonotic disease transmission. Related ethical questions include the appropriate selection of clinical trial participants, challenges with obtaining informed consent, animal rights and welfare considerations, and cost. Research involving recently deceased humans has also emerged as a potentially novel way to understand how xeno-organs will impact the human body. Clinical xenotransplantation and research involving decedents also raise ethical questions and will require consensus regarding regulatory oversight and protocol review. These considerations and the related opportunities for xenotransplantation research were discussed in a workshop sponsored by the National Heart, Lung, and Blood Institute, and are summarized in this meeting report.

Abstract
BACKGROUND Subcutaneous emphysema is a condition where air becomes trapped under the skin, typically resulting from surgery or skin trauma. It is mostly localized and its occurrence in blood donors is exceedingly rare. Phlebotomy poses minimal risk of subcutaneous emphysema, but procedural errors may lead to such complications. STUDY DESIGN AND METHOD This is a case report of 29-year-old repeat blood donor who experienced subcutaneous emphysema following blood donation. The donor was vigorously squeezing sponge ball during donation resulting in displacement of the needle which required readjustment. Post-donation, the donor reported a crackling sensation and mild swelling near phlebotomy site. Non-contrast computed tomography (NCCT) scans confirmed subcutaneous emphysema, attributing its development to air trapping in subcutaneous plane due to ball valve mechanism. RESULTS Computed tomography (CT) imaging revealed subcutaneous emphysematous changes in the right cubital region and no evidence of hematoma. The swelling spontaneously subsided in 10-12 days without any intervention. The case underscores the importance of differentiating subcutaneous emphysema from common complications like hematoma. DISCUSSION Subcutaneous emphysema in blood donors is exceptionally rare but should be managed with clear communication. Donors should be reassured that the condition, although rare, is benign and self-resolving. Healthcare providers should be equipped to handle such rare complications, offering appropriate care and documenting incidents for future prevention.

Abstract
OBJECTIVE The aim of our study was to assess if the addition of PRGF to healthy human sperm affects its motility and vitality. METHODS This was a prospective study, with 44 sperm donors on whom sperm analysis was performed. Nine mL of blood was collected and PRGF was obtained using PRGF-Endoret® technology. The influence of different dilutions of PRGF (5%, 10%, 20%, 40%) applied to 15 sperm donors was compared, and sperm motility was assessed after 30 minutes. In the second part of the study, 29 sperm donors were studied to analyze the influence of 20% dilution of PRGF at 15, 30 and 45 minutes in fresh and thawed sperm samples. Motility was assessed after the addition of PRGF and after analysis each aliquot was frozen. After thawing, concentration and motility were assessed at the same time periods. RESULTS There were no differences in sperm motility in fresh samples between dilutions of PRGF when assessed 30 minutes after administration, nor between them, nor when compared to the control group immediately prior to treatment. No trend was observed between motility and PRGF dilution in linear regression analysis. There were no significant differences in thawed samples. CONCLUSIONS The administration of 20% PRGF dilution had no effect on sperm motility compared to samples without PRGF. In addition, there was no change in sperm vitality when comparing samples with and without PRGF. More studies focusing on subnormal sperm samples, analyzing different PRGF concentrations and increasing the number of study variables are needed.

Abstract
BACKGROUND Mixed reality (MR), a form of virtual reality (VR), provides an immersive and interactive experience for the user. Given VR's benefits in patients undergoing needle insertion procedures, MR's usability, impact on anxiety, and safety were evaluated in the blood donation setting. STUDY DESIGN AND METHODS Whole blood donors ≥18 years old (yo) were enrolled at two blood centers and provided a MR headset with independently developed software to wear during blood donation. Pre- and post-donation questionnaires were conducted, and reaction data were reviewed. A post-study questionnaire was also completed by staff who assisted donors with MR. Descriptive statistics, bivariate analyses, and multinomial logistic regression were performed, and p values determined statistical significance between variables. RESULTS A total of 282 donors completed the study. 84% wanted to try MR because it seemed fun/different/cool/interesting, and most staff (69%) and donors (68%) found MR easy to use. Baseline subjective anxiety, reported by 50.3% (more often in females, first-time donors, and donors <20 yo), was reduced by MR in 68.4% of donors, and there was a 3.6 times higher odds of anxiety reduction with MR. 54% of donors with baseline anxiety would use MR again with the highest future interest in young donors. Donor reactions while using MR were mild and included pre-faint reactions and hematomas. CONCLUSION This study demonstrates the potential of MR in reducing donor anxiety, its feasibility during blood donation, and its safety in blood donors. MR is an innovative technology that holds promise to increase donor engagement, satisfaction, and retention.

Abstract
BACKGROUND The quality and quantity of hematopoietic stem cells in apheresis products are essential to the success of peripheral blood hematopoietic stem cell transplantation (PB-HSCT). While the flow cytometry measurement of CD34+ cells as a golden standard for stem cell count is labor and cost-intensive, hematopoietic progenitor cell number evaluated by XN Sysmex series automated hematology analyzers (XN-HPC) is suggested as a surrogate marker. MATERIALS AND METHODS We evaluated the correlation and consistency of XN-HPC and CD34+ cell count in apheresis samples from both allogeneic donors and autologous patients during PB-HSCT. RESULTS Good correlation and consistency were observed between XN-HPC and CD34+ cell counts in harvests collected from healthy donors (R = .852) rather than autologous patients (R = .375). Subgroup analysis showed that the correlation was especially poor when autologous patients used plerixafor as an additional mobilizer or were diagnosed with multiple myeloma (MM). In the setting of allogeneic transplantation, the correlation coefficients were even better in samples from non-first-round apheresis (R = .951), with high white blood cell (WBC) counts (R = .941), or having successful engraftment within 2 weeks (R = .895). ROC analysis suggested that an optimal XN-HPC count of 1127 × 106 /L best predicted a sufficient yield of CD34+ stem cells, with diagnostic sensitivity and specificity being 92% and 72%, respectively (AUC = 0.852). CONCLUSIONS XN-HPC is a sufficient quantitative marker for stem cell assessment of harvest yield in allogeneic but not autologous HSCT.

Abstract
Donor shortage is a major problem in lung transplantation (LTx), and the use of lungs from elderly donors is one of the possible solutions in a rapidly aging population. However, the utilization of organs from donors aged >65 years has remained infrequent and may be related to a poor outcome. To investigate the molecular events in grafts from elderly donors early after LTx, the left lungs of young and old mice were subjected to 1 hour of ischemia and subsequent reperfusion. The left lungs were collected at 1 hour, 1 day, and 3 days after reperfusion and subjected to wet-to-dry weight ratio measurement, histological analysis, and molecular biological analysis, including RNA sequencing. The lungs in old mice exhibited more severe and prolonged pulmonary edema than those in young mice after ischemia reperfusion, which was accompanied by upregulation of the genes associated with inflammation and impaired expression of cell cycle-related genes. Apoptotic cells increased and proliferating type 2 alveolar epithelial cells decreased in the lungs of old mice compared with young mice. These factors could become conceptual targets for developing interventions to ameliorate lung ischemia-reperfusion injury after LTx from elderly donors, which may serve to expand the old donor pool.

Abstract
BACKGROUND AND OBJECTIVES The efficacy of COVID-19 convalescent plasma (CP) associates with high titres of antibodies. ConPlas-19 clinical trial showed that CP reduces the risk of progression to severe COVID-19 at 28 days. Here, we aim to study ConPlas-19 donors and characteristics that associate with high anti-SARS-CoV-2 antibody levels. MATERIALS AND METHODS Four-hundred donors were enrolled in ConPlas-19. The presence and titres of anti-SARS-CoV-2 antibodies were evaluated by EUROIMMUN anti-SARS-CoV-2 S1 IgG ELISA. RESULTS A majority of 80.3% of ConPlas-19 donor candidates had positive EUROIMMUN test results (ratio ≥1.1), and of these, 51.4% had high antibody titres (ratio ≥3.5). Antibody levels decline over time, but nevertheless, out of 37 donors tested for an intended second CP donation, over 90% were still EUROIMMUN positive, and nearly 75% of those with high titres maintained high titres in the second sample. Donors with a greater probability of developing high titres of anti-SARS-CoV-2 antibodies include those older than 40 years of age (RR 2.06; 95% CI 1.24-3.42), with more than 7 days of COVID-19 symptoms (RR 1.89; 95% CI 1.05-3.43) and collected within 4 months from infection (RR 2.61; 95% CI 1.16-5.90). Male donors had a trend towards higher titres compared with women (RR 1.67; 95% CI 0.91-3.06). CONCLUSION SARS-CoV-2 CP candidate donors' age, duration of COVID-19 symptoms and time from infection to donation associate with the collection of CP with high antibody levels. Beyond COVID-19, these data are relevant to inform decisions to optimize the CP donor selection process in potential future outbreaks.

Abstract
PURPOSE There are limited data examining the impact of both donor and recipient race on outcomes following orthotopic heart transplant (OHT). The purpose of this study was to evaluate the relationship between donor and recipient race and OHT outcomes. METHODS The United Network for Organ Sharing (UNOS) database was retrospectively reviewed from January 2000 to March 2018 for donor hearts. A comparison was conducted based on donor and recipient race (White, Black, Hispanic, Other/Unknown). Races for which there were limited numbers were excluded from the analysis (Asian, n = 1292; American Indian, n = 132; Pacific Islander, n = 132, Multiple ethnicities, n = 225). The primary endpoint was survival at 30 days, 1 year survival, and post-transplant rejection. Logistic and Cox models were used to quantify survival endpoints. RESULTS A total of 41 841 OHT were included. Of the recipients, 29 894 (71%) were White, 8475 (20%) were Black, and 3472 (8%) were Hispanic. Of the donors 27 783 (66%) were White, 6277 (15%) were Black, 6576 (16%) were Hispanic, and 1205 (3%) were Unknown/Other race. In a comparison of recipient demographics, White recipients were older (54.09 ± 12.21 years) compared to Black (49.44 ± 12.83 years) and Hispanic (49.97 ± 13.27 years) recipients. All other differences between groups were not clinically significant. Black recipients were more likely to receive a heart with an "urgent" status (probability .80) compared to White (.73) and Hispanic (.75) recipients (p < .001). Hispanic recipients were more likely to receive a transplant when listed as "non-urgent" (Probability .47) compared to White (.37) and Black (.30) recipients (p < .001). In terms of outcomes, compared to White recipients, Hispanic patients experienced a decreased 30-day survival (OR 1.27; p = .011) and 1-year survival (OR 1.17; p = .016). In comparing Donor/Recipient combinations compared to a White Donor/White Recipient combination, overall survival was decreased in White donor/African American recipient (HR 1.36; p < .001), African American donor/African American recipient (HR 1.41; p < .001) and Hispanic donor/African American recipient (HR 1.30; p < .001) combinations (Table 1). CONCLUSIONS African American and Hispanic recipients have decreased survival compared to White recipients after heart transplant. The African American donor does not decrease survival. Racial differences still exist in donor and recipient characteristics and recipient outcomes after OHT. Increasing the donor pool for all races and ethnicities would potentially benefit all recipients. Continued study is warranted in order to minimize these differences among recipients and identify factors that could be contributing to decreased survival, in order to optimize outcomes for African American and Hispanic recipients post-transplant and eliminate disparities.

Abstract
Worldwide, there is increasing acknowledgment of the importance of getting access to ancestry information. More and more countries facilitate access to this information through law changes and voluntary contact-services. In the Netherlands, the state-funded Fiom KID-DNA database was established in 2010 to facilitate information and/or contact exchange between those people who are genetically related as a result of donor-assisted conception. By the end of 2021, 846 donors and 2355 donor-conceived people are registered in the database. For 25% of the donors a link was found with one or more donor-conceived people, and 39% of the donor-conceived people were linked to a donor-profile. Fiom offers support by professionally qualified staff throughout the entire process from registration to contact to donor-conceived people, donors and their relatives. During the period of more than 10 years several challenges emerged; how does a state-funded DNA database function in the area of commercial DNA databases?; what can be learned from the continuous growing donor-conceived half-siblings networks?; how to deal with malpractices from the past and how to cope with ageing donors?

Abstract
Blood donors and voluntary blood donations are essential for ensuring the blood supply that can be maintained by good patient blood management (PBM) practices. This review article explores the role of blood donation in PBM and highlights the importance of donor screening and selection processes in different regions worldwide. The donor health questionnaires and the focused physical examination guidelines have changed in the last decade to increase donor and recipient safety. This article also discusses the status of transfusion practices, including the challenges of ensuring a safe blood supply. Significant among these are the effects of the COVID-19 pandemic on the blood supply chain and the impact of an aging donor population, especially. Promoting autologous donations and other blood conservation strategies are suggested to mitigate these issues. The role of replacement donors and the upper age limit for voluntary blood donation may be decided based on the demography and donor pool. The involvement of C-suite executives is also critical in implementing and running a successful PBM program. The review highlights how these different aspects of blood donation are integral to a successful PBM program and the safety of patients who receive blood transfusions.

Abstract
BACKGROUND Severe T-cell lymphopenia of uncertain clinical significance has been observed in frequent apheresis platelet donors. Two commonly used plateletpheresis instruments are the Trima Accel, which uses a leukoreduction system (LRS) chamber to trap leukocytes and the Fenwal Amicus, which does not use an LRS chamber. STUDY DESIGN AND METHODS We performed an international, multicenter, observational study comparing T-cell populations in frequent platelet donors collected exclusively using the Trima instrument (n = 131) or the Amicus instrument (n = 77). Age- and sex-matched whole blood donors (n = 126) served as controls. RESULTS CD4+ T-cell counts <200 cells/μL were found in 9.9% of frequent Trima (LRS+) platelet donors, 4.4% of frequent Amicus (LRS-) platelet donors, and 0 whole blood donors (p < .0001). CD4+ T-cell counts <200 cells/μL were only seen in platelet donors with ≥200 lifetime donations. In multivariable analysis, age, lifetime donations, and instrument (Trima vs. Amicus) were independent risk factors for lymphopenia. In 40 Trima platelet donors, a plasma rinseback procedure was routinely performed following platelet collections. No Trima platelet donors receiving plasma rinseback had a CD4+ T-cell count <200 cells/μL versus 13/91 Trima platelet donors not receiving plasma rinseback (p = .01). DISCUSSION Recurrent bulk lymphocyte removal appears to contribute to the development of T-cell lymphopenia in frequent, long-term platelet donors. Lymphopenia is more common when an LRS chamber is used during platelet collection but can occur without an LRS chamber. Blood centers using LRS chambers can mitigate donor lymphopenia by performing plasma rinseback.

Abstract
BACKGROUND The utility of unrelated donor registries that support allogeneic hematopoietic cell transplantation could be optimized through greater understanding of redundancy and rareness of HLA phenotypes. METHODS HLA phenotype rareness was determined using known HLA haplotype frequencies. Donor redundancy was determined through pairwise comparison of donor HLA profiles within an inventory. RESULTS Among 61,730 registrants in the Canadian Blood Services (CBS) Stem Cell Registry (SCR) with high resolution HLA typing at 5 loci, 6.6% of HLA phenotypes were redundant with variation across ethnic groups (8.3% of Caucasian phenotypes; 8% of Native American/First Nations, 4.4% of Asia-Pacific Islanders (API), 2.1% of Hispanic, 0.7% of African-American (AFA), and 4.5% of other ethnicities). A total of 18.5% of registrants had redundant HLA phenotypes with variation across ethnic groups. All 3716 cord blood units in the CBS's cord blood bank (CBB) had high resolution HLA typing at 5 loci and 202 units were redundant (5.4%) comprising 78 HLA phenotypes, with varying rareness. Repeated HLA phenotypes were from Caucasian donors (77%), multiple ethnicity (13%), API (9%), and AFA (1%). Registrants and CBUs with AFA ethnicity had the rarest phenotypes while Caucasian ethnicity was associated with the most common HLA phenotypes. CONCLUSIONS Redundancy was greater in the SCR compared to the CBB and was most common with CAU ethnicity. Recruiting non-Caucasian registrants and continued cord blood banking should reduce redundancy. A sub-inventory of redundant donors and cord blood units could support new uses for donor-supported cellular therapies that do not require HLA matching.

Abstract
Lipid droplets (LDs) are dynamic complex organelles involved in various physiological processes, and their number and activity are linked to multiple diseases, including cancer. In this study, we have developed LD-specific near-infrared (NIR) light-responsive nano-drug delivery systems (DDSs) based on chalcone derivatives for cancer treatment. The reported nano-DDSs localized inside the cancer microenvironment of LDs, and upon exposure to light, they delivered the anticancer drug valproic acid in a spatiotemporally controlled manner. The developed systems, namely, 2'-hydroxyacetophenone-dimethylaminobenzaldehyde-valproic (HA-DAB-VPA) and 2'-hydroxyacetophenone-diphenylaminobenzaldehyde-valproic (HA-DPB-VPA) ester conjugates, required only two simple synthetic steps. Our reported DDSs exhibited interesting properties such as excited-state intramolecular proton transfer (ESIPT) and aggregation-induced emission (AIE) phenomena, which provided advantages such as AIE-initiated photorelease and ESIPT-enhanced rate of photorelease upon exposure to one- or two-photon light. Further, colocalization studies of the nano-DDSs by employing two cancerous cell lines (MCF-7 cell line and CT-26 cell line) and one normal cell line (HEK cell line) revealed LD concentration-dependent enhanced fluorescence intensity. Furthermore, systematic investigations of both the nano-DDSs in the presence and absence of oleic acid inside the cells revealed that nano-DDS HA-DPB-VPA accumulated more selectively in the LDs. This unique selectivity by the nano-DDS HA-DPB-VPA toward the LDs is due to the hydrophobic nature of the diphenylaminobenzaldehyde (mimicking the LD core), which significantly leads to the aggregation and ESIPT (at 90% volume of fw, ΦF = 20.4% and in oleic acid ΦF = 24.6%), respectively. Significantly, we used this as a light-triggered anticancer drug delivery model to take advantage of the high selectivity and accumulation of the nano-DDS HA-DPB-VPA inside the LDs. Hence, these findings give a prototype for designing drug delivery models for monitoring LD-related intracellular activities and significantly triggering the release of LD-specific drugs in the biological field.

Abstract
Nitric oxide (NO) is a gaseous molecule that has a central role in signaling pathways involved in numerous physiological processes (e.g., vasodilation, neurotransmission, inflammation, apoptosis, and tumor growth). Due to its gaseous form, NO has a short half-life, and its physiology role is concentration dependent, often restricting its function to a target site. Providing NO from an external source is beneficial in promoting cellular functions and treatment of different pathological conditions. Hence, the multifaceted role of NO in physiology and pathology has garnered massive interest in developing strategies to deliver exogenous NO for the treatment of various regenerative and biomedical complexities. NO-releasing platforms or donors capable of delivering NO in a controlled and sustained manner to target tissues or organs have advanced in the past few decades. This review article discusses in detail the generation of NO via the enzymatic functions of NO synthase as well as from NO donors and the multiple biological and pathological processes that NO modulates. The methods for incorporating of NO donors into diverse biomaterials including physical, chemical, or supramolecular techniques are summarized. Then, these NO-releasing platforms are highlighted in terms of advancing treatment strategies for various medical problems.

Abstract
BACKGROUND The Department of Health and Human Services' National Blood Collection and Utilization Survey (NBCUS) has been conducted biennially since 1997. Data are used to estimate national blood collection and use. Supplemental data from the 2021 NBCUS not presented elsewhere are presented here. METHODS Data on survey participation, donor characteristics, blood component cost, transfusion-associated adverse reactions, and implementation of blood safety measures, including pathogen-reduction of platelets, during 2021, were analyzed. Comparisons are made to 2019 survey data where available (2013-2019 for survey participation). RESULTS During 2021, there were 11,507,000 successful blood donations in the United States, a 4.8% increase from 2019. Persons aged 45-64 years accounted for 42% of all successful blood donations. Donations by persons aged 65 years and older increased by 40.7%, while donations among minorities and donors aged <25 years decreased. From 2019 to 2021, the median price hospitals paid per unit of leukoreduced red blood cells, leukoreduced and pathogen-reduced apheresis platelets, and fresh frozen plasma increased. The largest increase in price per unit of blood component in 2021 was for leukoreduced apheresis platelets, which increased by ~$51. Between 2019 and 2021, the proportion of transfusing facilities reporting use of pathogen-reduced platelets increased, from 13% to 60%. Transfusion-related adverse reactions declined slightly between 2019 and 2021, although the rate of transfusion-transmitted bacterial infections remained unchanged. CONCLUSION During 2021, blood donations increased nationally, although donations from those aged <25 years and minorities declined. The prices hospitals paid for most blood products increased, as did the use of pathogen-reduced platelets.

Abstract
BACKGROUND AND OBJECTIVES Plasma has become an essential ingredient for various medical treatments. Many blood collection agencies rely on voluntary non-remunerated donation when collecting plasma, but at present many do not collect sufficient plasma to meet domestic demands. This rapid review sought to explore the factors that have been found to influence people's decisions to donate plasma to inform future research. METHODS Searches were conducted in PubMed, PsycINFO, Social Sciences Citation Index and CINAHL for peer-reviewed journal articles that discussed plasma donation and the factors associated with donor behaviour. Pertinent information from included articles was extracted and arranged in themes. RESULTS In total, 33 articles were included in this review. Three main themes were identified by the authors. The first focused on site-level factors related to blood collection agencies' engagement with plasma donors and their influence on plasma donation experiences. The second theme considered how individual characteristics and experiences influence willingness to donate plasma. The third theme examined social and cultural-level factors, such as how social networks and community shape perceptions and experiences with donation. CONCLUSION Our findings suggest that the current understanding of plasma donation is focused mainly on converting whole blood donors and also centres on individual-level factors to donation. Further research must examine what factors attract non-whole blood donors to become plasma donors, focusing on broader social-level influences. This review will inform policies and interventions for blood collection agencies to increase plasma donors.

Abstract
BACKGROUND Individual risk assessment allows donors to be evaluated based on their own behaviors. Study objectives were to assess human immunodeficiency virus (HIV) risk behaviors in men who have sex with men (MSM) and estimate the proportion of the study population who would not be deferred for higher risk HIV sexual behaviors. STUDY DESIGN AND METHODS Cross-sectional survey and biomarker assessment were conducted in eight U.S. cities. Participants were sexually active MSM interested in blood donation aged 18-39 years, assigned male sex at birth. Participants completed surveys during two study visits to define eligibility, and self-reported sexual and HIV prevention behaviors. Blood was drawn at study visit 1 and tested for HIV and the presence of tenofovir, one of the drugs in oral HIV pre-exposure prophylaxis (PrEP). Associations were assessed between HIV infection status or HIV PrEP use and behaviors, including sex partners, new partners, and anal sex. RESULTS A total of 1566 MSM completed the visit 1 questionnaire and blood draw and 1197 completed the visit 2 questionnaire. Among 1562 persons without HIV, 789 (50.4%) were not taking PrEP. Of those not taking PrEP, 66.2% reported one sexual partner or no anal sex and 69% reported no new sexual partners or no anal sex with a new partner in the past 3 months. CONCLUSION The study found that questions were able to identify sexually active, HIV-negative MSM who report lower risk sexual behaviors. About a quarter of enrolled study participants would be potentially eligible blood donors using individual risk assessment questions.

Abstract
Background Iran's health system is facing increasing costs and a lack of resources. Developing the financial participation of donors is one of the ways to strengthen the financial health system. Objective This research was done to explain the barriers to donors' participation in the field of health. Method This qualitative study was conducted in 2022 using semi-structured interviews with 22 experts, health donors, policymakers, and managers in Iran. The conventional content analysis method was also used for data analysis. Results The review and classification of the interviews showed that the participation of donors in the health system includes four main issues: the incompleteness of legal processes, the lack of continuous communication with the charity, management, and resources problems, and the insufficient awareness of the donors about the problems and needs of the health system and 18 subtopics. Conclusions Donors play an important role in financing, developing resources, providing health services, and financially supporting patients in Iran's health system. Therefore, by recognizing and removing obstacles to the participation of donors, policymakers and managers of the health system should target the participation of donors with proper planning, organization, guidance, and supervision, and avoid parallel work and waste of resources.

Abstract
Hydrogen sulfide (H2 S) is an important gaseous signalling molecule known to be critically involved in regulating cellular redox homeostasis. As the beneficial and therapeutic effects of H2 S in pathophysiology, such as in cardiovascular and neurodegenerative diseases, have emerged, so too has the drive for the development of H2 S-releasing compounds (aka donors) and their therapeutic applications. Most reported donor compounds singularly release H2 S through biocompatible triggers. An emerging area in the field is the development of compounds that can co-deliver H2 S with other drugs or biologically relevant species, such as reactive oxygen and nitrogen species (ROS and RNS, respectively). These H2 S-based dual donors and hybrid drugs are expected to offset negative side effects from individual treatments or achieve synergistic effects rendering them more clinically effective. Additionally, considering that molecules exist and interact physiologically, dual donors may more accurately mimic biological systems as compared to single donors and allow for the elucidation of fundamental chemistry and biology. This review focuses on the recent advances in the development of H2 S-based dual donors and hybrid drugs along with their design principles and synergistic effects.

Abstract
The influence of the diet and nutritional status of milk donors on the nutritional composition of donor human milk (DHM) is unknown. The present study aimed to determine the nutritional profile of DHM and the associations between donors' dietary intake and nutritional status and the micronutrient and lipid composition in DHM. For this purpose, 113 donors completed a food frequency questionnaire, provided a five-day weighed dietary record, and collected milk for five consecutive days. Nutrient determinations in donors' erythrocytes, plasma, urine, and milk were performed. Multiple linear regressions were conducted for the evaluation of the associations. We highlight the following results: DHM docosahexaenoic acid (DHA) was positively associated with donors' plasma DHA content and donors' DHA intake (R2 0.45, p < 0.001). For every 1 g/day DHA intake, an increase of 0.38% in DHA content and 0.78% in total omega-3 content was observed in DHM (R2 0.29, p < 0.001). DHM saturated fatty acids were positively associated with erythrocyte dimethyl acetals, plasma stearic acid, trans fatty acids intake, and breastfeeding duration and negatively associated with erythrocyte margaroleic acid (R2 0.34, p < 0.01). DHM cholecalciferol was associated with plasma cholecalciferol levels and dairy intake (R2 0.57, p < 0.01). Other weaker associations were found for free thiamin, free riboflavin, pyridoxal, dehydroascorbic acid, and the lipid profile in DHM. In conclusion, the diet and nutritional status of donors influence the fatty acid profile and micronutrient content of DHM.

Abstract
This article presents data from experiments to determine the cryoresistance of Charollais sheep embryos, depending on the stage of embryo development and the method of freezing, as well as the results of embryo transfer. The study design consisted of a study on the cryopreservation of ewe embryos at different developmental stages (early, 2-8 blastomeric and late, at the morula/blastocyst stage), two cryopreservation protocols (slow freezing and ultra-fast vitrification), and embryo transfer of cryo- and fresh embryos. Embryos from Charollais sheep donors (n = 12) were recovered after induction of superovulation. The embryos were recovered surgically (laparotomy) on days 2 and 6 after insemination. Before there was transfer to recipients, part of embryos was cryopreserved using standard slow freezing and ultra-fast vitrification methods. The average ovarian response was 7.54 ovulations per donor, and 5.83 embryos per donor were collected. No effect of the cryopreservation method and embryo development stage on the preservation of the morphological structure of embryos was found. There were no significant differences in the survival rate of cryoembryos at different development stages, frozen using different techniques, and after transfer to recipients. Differences in cryoresistance between embryonic developmental stages in favor of the morula/blastocyst stage were found (survival after thawing 86.4% vs. 75.0% in early embryos). At different stages of development, the survival rate of fresh embryos (45.8%) compared to cryopreserved ones (30.2%) was significantly higher (p < 0.05), while among fresh ones, the best survival rate (50.0%) was observed after the transfer of morules and blastocysts.

Abstract
Considering the important cytoprotective and signaling roles but relatively narrow therapeutic index of hydrogen sulfide (H2S), advanced H2S donors are required to achieve a therapeutic effect. In this study, we proposed glutathione dithiophosphates as new combination donors of H2S and glutathione. The kinetics of H2S formation in dithiophosphate solutions suggested a continuous H2S release by the donors, which was higher for the dithiophosphate of reduced glutathione than oxidized glutathione. The compounds, unlike NaHS, inhibited the proliferation of C2C12 myoblasts at submillimolar concentrations due to an efficient increase in intracellular H2S. The H2S donors more profoundly affected reactive oxygen species and reduced glutathione levels in C2C12 myocytes, in which these parameters were elevated compared to myoblasts. Oxidized glutathione dithiophosphate as well as control donors exerted antioxidant action toward myocytes, whereas the effect of reduced glutathione dithiophosphate at (sub-)micromolar concentrations was rather modulating. This dithiophosphate showed an enhanced negative inotropic effect mediated by H2S upon contraction of the atrial myocardium, furthermore, its activity was prolonged and reluctant for washing. These findings identify glutathione dithiophosphates as redox-modulating H2S donors with long-acting profile, which are of interest for further pharmacological investigation.

Abstract
BACKGROUND In 2021, Canada implemented a pilot plasma program allowing some sexually active men who have sex with men (including but not limited to gay and bisexual men; gbMSM) to donate plasma. Changes to plasma donation policy could help address inequities in access to plasma donation and increase Canada's domestically collected plasma supply if more gbMSM donate as a result. We aimed to (1) examine views regarding plasma donation and the pilot program prior to implementation and (2) identify modifiable theory-informed predictors of gbMSM's intention to donate plasma. METHODS We developed, piloted, and disseminated a questionnaire informed by the Theoretical Domains Framework (TDF). We recruited gbMSM in London (ON) and Calgary (AB) to an anonymous, online cross-sectional survey. RESULTS A total of 246 gbMSM completed the survey. On scales from 1 (strongly disagree) to 5 (strongly agree), general intention to donate was high (mean = 4.24; SD = 0.94). The pilot program itself was mostly acceptable (mean = 3.71, SD = 1.16), but the intention to donate under the unique requirements of the pilot program was lower than general intention (mean = 3.58; SD = 1.26). Two domains from the theoretical domains framework (TDF) (beliefs about consequences of donating plasma and social influences) were independently associated with general intention to donate. DISCUSSION The pilot plasma program as an incremental step toward more inclusive policies was mostly viewed as acceptable by the impacted communities. Historical and ongoing exclusions create unique barriers to donation. There are clear opportunities for developing theory-informed interventions to support gbMSM to donate plasma as policies continue to become more inclusive and more become eligible to donate.

Abstract
BACKGROUND Many blood operators around the world face the challenge of increasing the number of donors of African ancestry to meet the transfusion needs of people living with sickle cell disease. This article reports results of the barriers to blood donation for young adults (aged 19-35) in Canada who identify as African, Caribbean, or Black. STUDY DESIGN AND METHODS A community-based qualitative study was conducted by researchers from community organizations, blood operator, and universities. In-depth focus groups and interviews (n = 23) were conducted from Dec 2021 to Apr 2022 and thematic analysis was completed. RESULTS Applying a socio-ecological model, multiple levels of interacting barriers to blood donation were identified. These included macro-level barriers (e.g., systemic racism, mistrust of the healthcare system, sociocultural beliefs and views about blood and sickle cell disease), mezzo-level barriers (e.g., deferral criteria, minimum hemoglobin levels, donor questionnaire, access, parental concerns), and microlevel barriers (e.g., limited knowledge of blood needs for people with sickle cell disease, lacking information about blood donation process, fear of needles, personal health concerns). DISCUSSION This study is the first to focus on barriers to donation for African, Caribbean, and Black young adults across Canada. Parental concerns, informed by parents' experiences of inequitable healthcare and mistrust, emerged as a novel finding in our study population. Results suggest that higher order (macro-level) barriers influence and may reinforce lower order (mezzo- and microlevel) barriers. As such, interventions aimed at addressing barriers to donation should keep in view all levels with particular attention paid to higher order barriers.

Abstract
BACKGROUND Platelet demand continues to rise and US hospitals frequently face shortages. The peak median age of apheresis platelet donors (APD) is believed to have increased over the last decade, raising concerns that the APD base is not being adequately replenished with young donors. STUDY DESIGN/METHODS American Red Cross (ARC) apheresis platelet collections were evaluated from calendar years 2010 through 2019. APD, products per procedure/split rate (PPP) and donation frequencies were stratified into age groups. RESULTS/FINDINGS The number of unique APD from calendar year 2010 through 2019 in the ARC donor pool increased from 87,573 to 115,372 donors, representing a 31.7% overall growth. Donors in the 16-40 year-old (y) age group increased by 78.8% overall, with the largest absolute increases seen in the 26-30 y (4852 donors, 99.9% growth), followed by the 31-35 y (3991, 94.1%) group. Donors aged 56+ increased by 50.4% overall, with the largest increase seen in the 66-70 y (5988 donors, 108.1% growth) group. Middle-aged donors, aged 41-55 y, demonstrated a decrease of 16.5%. Over the last decade, the youngest age groups (16-40 y) comprised 61.3% of first-time donors (FTD). Annual donation frequency increased with increasing age and PPP. The highest donation frequencies were seen in the oldest age groups. CONCLUSION Although the peak median age of APD increased over the study period, relative contribution of the 16-40 y APD base also increased. Older donors exhibited the highest donation frequencies and thus contributed the largest volume of apheresis platelet units. Platelet donor activity declined in the middle age (41-55 y) group.

Abstract
At a time when transplantable organs are in a shortage, few cases have noted the reuse of donor hearts in a second recipient in an effort to expand the donor network. Here, we present a case in which an O Rh-positive donor heart was first transplanted into a B Rh-positive recipient and later successfully retransplanted into a second O Rh-positive recipient 10 days after the initial transplant at the same medical center. On postoperative day 1, the first recipient, a 21-year-old man with nonischemic cardiomyopathy, sustained a devastating cerebrovascular accident with progression to brain death. With preserved left ventricle and mildly depressed right ventricle function, the heart was allocated to the second recipient, a 63-year-old male patient with familial restrictive cardiomyopathy. The bicaval technique was used, and the total ischemic time was 100 minutes. His postoperative course was uncomplicated with no evidence of rejection on 3 endomyocardial biopsies. Follow-up transthoracic echocardiogram revealed a left ventricular ejection fraction of 60% to 70%. Seven months posttransplant, the second recipient was doing well with appropriate left and right ventricular function. With careful organ selection, short ischemic time, and proper postoperative care, retransplant of donor hearts may be an option for select patients in need of heart transplant.

Abstract
The objective of this study was to investigate the significance of portal vein reconstruction in segment IV of the liver on early postoperative liver function recovery in split liver transplantation. The clinical data of patients of right trilobe split liver transplantation in our center were analyzed and divided into two groups, including a group without portal vein reconstruction and a group with portal vein reconstruction. Clinical data of alanine aminotransferase (ALT), aspartate transaminase (AST), albumin (ALB), creatinine (Cr), total bilirubin (TB), alkaline phosphatase (ALP), gamma-glutamyl Transferase (GGT), lactic acid (Lac), and international normalized ratio (INR) levels were analyzed. The technique of segment IV portal vein reconstruction is beneficial to the early postoperative recovery of liver function. Statistically, there was no significant effect of portal vein reconstruction in the IV segment of the liver on the recovery of liver function within 1 week after split liver transplantation. There was no significant difference in survival rate between the control group and reconstruction group over the 6 months follow-up period after surgery.

Abstract
BACKGROUND Cord blood (CB) is a cell source for hematopoietic stem cell transplantation. In 2019, the percentage of births with CB collected for banking was only 3% nationally and 0.05% in our state. To increase CB donations, we need to understand pregnant women's awareness and knowledge of, plus barriers and facilitators to, CB banking (CBB). STUDY DESIGN AND METHODS We recruited 289 women in their third trimester from an academic obstetric clinic between October 2020 and May 2021. Women attending this clinic come from all parts of the state in addition to local city residents. After agreeing to participate, participants completed a survey using Research Electronic Data Capture (REDCap). Data were analyzed using SAS version 9.4. RESULTS Exactly 58.9% of participants had heard of CBB, but only 26.53% understood its purpose; 10.03% indicated someone had discussed CBB with them, and 61.3% were undecided about it. The preferred source of information was the clinic provider (82.1%), followed by CB bank staff (36.8%). The requested mode for receiving information was face-to-face with their provider, including written materials. Income, education, and marital status did not have a significant influence on information preferences. DISCUSSION Lack of knowledge continues to be a major barrier to CBB. Developing educational interventions based on womens' preferences may increase understanding of CBB. Study participants preferred that the healthcare provider deliver this information. This study was done in a primarily rural, southern state, while previous studies were in larger metropolitan areas, yet results are comparable.

Abstract
BACKGROUND Previous mixed findings on the associations between whole blood (WB) donation and risk of cardiovascular diseases (CVD) may in part reflect inadequate adjustment for the "healthy donor effect" (HDE). METHODS We used the Sax Institute's 45 and Up Study linked with blood donation history and other health-related databases to examine the association between regular, high-frequency WB donation and the risk of CVD. To mitigate the impact of HDE, we used a "5-years qualification period," in which donors must donate at least 1 WB donation in the 1st and 5th year of "qualification period." We then compared the risk of CVD in the years following the "qualification period" between the regular high-frequency WB donors (≥2 WB donation in each qualification year) and others using Cox proportional-hazards models. Analyses were adjusted for potential confounders, such as sociodemographic, lifestyle, and health-related variables, and results are reported separately for male and female donors. RESULTS A total of 2736 male and 2917 female donors were included in the analyses. The median years of follow-up per donor was 5.84 years (Q1-Q3, 5.47-6.23). The rate of CVD hospitalization was 11.20 and 4.50 per 1000 person-years for males and females, respectively. In fully adjusted models, the risk (hazard ratio) of CVD in regular high-frequency donors compared to other donors was 0.93 (95% Confidence Interval (CI), 0.68-1.29) for males and 0.79 (95% CI, 0.49-1.28) for females. CONCLUSIONS We did not observe a statistically significant reduction of CVD risk in regular, high-frequency WB donors when adjusted for potential confounders.

Abstract
OBJECTIVE Growing evidence suggests multiple pathophysiological mechanisms linking red blood cells (RBC) transfusions to thrombosis. This study examined blood donor, component, and recipient factors which may be associated with thromboembolic outcomes following RBC transfusion. METHODS We utilized the Recipient Epidemiology Donor Evaluation Study-III (REDS-III) database on patients transfused in 12 hospitals between 2013-2016. Stratified Cox proportional hazards regression models with time-dependent exposures were used to examine associations of donor and component modification characteristics on venous thromboembolism (VTE) in patients transfused RBC units. RESULTS 59,603 patients were transfused 229,500 RBC units during 79,298 hospitalizations with post-transfusion VTE occurring in 1869 (2.4%) of patients. In adjusted regression analyses, a per RBC-unit risk of VTE was present for gamma irradiation (HR = 1.03; 95% CI: 1.02-1.03), female donor sex (HR = 1.01; 95% CI: 1.00-1.01), storage duration greater than 5 weeks (HR = 1.01; 95% CI: 1.01-1.02), AS-1 storage solution (HR = 1.01; 95% CI: 1.00-1.01), and apheresis-derived collections (HR = 1.01; 95% CI: 1.01-1.02). Among recipient factors, male sex (HR = 1.03; 95% CI: 1.02-1.04), pre-transfusion hemoglobin level (HR = 0.94; 95% CI: 0.94-0.94), body mass index strata (HR = 1.11; 95% CI: 1.08-1.14), and principal diagnoses including malignancy (HR = 1.13; 95% CI: 1.10-1.16), cardiac arrest (HR = 1.38; 95% CI:1.07-1.77) and hip fracture (HR = 1.59; 95% CI:1.53-1.66) were associated with VTE in adjusted analyses. DISCUSSION We identified several donor, component, and recipient-specific factors associated with VTE in transfused hospitalized adult patients. In adjusted models, the dose-dependent associations of donor and component-specific factors with VTE were modest and unlikely to be clinically significant in the majority of transfused patients. Additional mechanistic and clinical studies linking blood donor and component factors with thrombotic outcomes are needed.

Abstract
BACKGROUND Genomic testing is already used by blood collection agencies (BCAs) to identify rare blood types and ensure the best possible matching of blood. With ongoing technological developments, broader applications, such as the identification of genetic markers relevant to blood donor health, will become feasible. However, the perspectives of blood donors (and potential blood donors) on routine genomic testing of donor blood are under-researched. STUDY DESIGN AND METHODS Eight online Focus Groups were conducted: four with donors and four with non-donors. Participants were presented with three hypothetical scenarios about the current and possible future applications of genomic testing: Performing rare blood type testing; identifying donors with genetic markers associated with iron metabolism; and identifying donors with genetic markers associated with bowel cancer. RESULTS Testing to identify rare blood types was perceived to be an appropriate application for the BCA to undertake, while identifying markers associated with iron metabolism and cancer genetic markers were only partially supported. Participants raised concerns about the boundaries of acceptable testing and the implications of testing for privacy, data security, and health insurance. Perspectives of donors and non-donors on all scenarios were similar. DISCUSSION The principles of who benefits from genomic testing and the perceived role of BCAs were key in shaping participants' perspectives. Participants generally agreed that testing should be directly related to blood donation or be of benefit to the recipient or donor. Findings indicate that consent and communication are key to the acceptability of current and expanded genomic testing.

Abstract
BACKGROUND AND OBJECTIVES Two years after implementing a new national donor vigilance system, the Danish Haemovigilance Committee conducted a nationwide survey to evaluate the implementation among different staff groups. We present the results here. MATERIALS AND METHODS The study was designed as an anonymous online survey to evaluate the satisfaction with the new registration, understanding of the parameters used and the user-friendliness. The REDCap platform was used. The questionnaire consisted of 22 questions. Ordinal variables were answered using five-point Likert scale (1 = strongly disagree to 5 = strongly agree). The data were analysed using descriptive statistics. Successful implementation was defined as mean overall satisfaction ≥4 and mean understanding of the individual components (adverse reaction category, severity and imputability) in the registration ≥4. RESULTS In all, 104 staff members (77.9% donation staff) participated. The mean (SD) overall satisfaction among all participants was 3.96 (0.94), highest among medical doctors (4.43 (0.78)) and lowest for administrative or other personnel (2.78 (1.09)). The mean scores for understanding the adverse reaction categories, severity and imputability were 3.92 (0.94), 3.92 (0.94) and 3.88 (1.00), respectively. Experience with a previous donor vigilance system was associated with lower scores. The most successful implementation programme included a medical doctor for introduction and a contact person. CONCLUSION The goal for successful implementation was not met. However, the overall attitude towards the new registration was positive and indicates that the system is suitable for different staff groups. Our results suggest that implementation could benefit from special attention to administrative staff and those accustomed to another donor vigilance system.

Abstract
BACKGROUND Minimizing the risk of vasovagal reactions (VVRs) can prevent donor harms and improve donor return. We report the results of a program to reduce VVR rates. STUDY DESIGN AND METHODS The program was implemented on June 11, 2017 and consisted in drinking water and eating a salty snack before donating blood, plasma, or platelets. All donations made during the "pre-program period" (October 11, 2015-June 10, 2017) and "post-program period" (June 11, 2017-May 11, 2019) were included. Study outcomes comprised VVRs (any severity) and syncopal VVRs, whether employee- or donor-reported. An interrupted time series (ITS) analysis proxied causality based on the "pre-program trend," the "immediate trend" (i.e., immediately before versus after the program), and the "post-program trend". The relative risk (RR) of VVR (along with confidence intervals [CIs]) was reported, overall and stratified by subgroups based on age, sex, donor type (i.e., first-time versus repeat), and donation type (i.e., whole blood versus apheresis). RESULTS The monthly VVR rate (any severity) dropped from 4.6% in the pre-program period to 4.3% in the post-program period, and never reached its pre-program level. The ITS analysis revealed a statistically significant and increasing pre-program trend (RR [95% CI] = 1.011 [1.002-1.020]), a statistically significant and decreasing immediate trend (RR [95% CI] = 0.848 [0.743-0.969]), and a non-statistically-significant and stable post-program trend (RR [95% CI] = 0.999 [0.993-1.006]). Similar trends were observed for nearly all high- and low-risk subgroups. No statistically significant trend was observed for syncopal VVRs. DISCUSSION These results suggest that the herein-described program durably reduced the incidence of VVRs (any severity) by ~15%.

Abstract
When the issue of donor assisted conception arises, two bioethical and legal issues have to be answered. Firstly, when can a donor be considered as a legal parent of a child who claims to have been born through his genetic material? Secondly, should anonymous sperm donation be allowed? In this article, these questions are answered according to Greek Law. Also, the author provides integrated solutions to legal problems.

Abstract
BACKGROUND AND OBJECTIVES Donor criteria for diabetes vary significantly. We describe our evolving policies for donors with diabetes, their contribution to the Canadian blood supply and their rate of syncopal reactions compared to other donors. MATERIALS AND METHODS All donors are asked if they have diabetes and have taken medications in the last 3 days. We assessed donors with diabetes on various medications, the number deferred over time, and syncopal reactions in donors with diabetes and other donors in our donor reaction database. RESULTS Policy changes allowing type 2 diabetic donors on oral hypoglycaemics alone, type 2 diabetic donors on oral medications and insulin and type 1 diabetic donors (all on insulin) to donate resulted in a decrease in deferrals from 450 to 22 donors annually. Of donors being treated with medication for diabetes, 11% are receiving insulin as part of their treatment. Syncopal reaction rates were low and not statistically different between diabetic and non-diabetic donors, although confidence intervals (CIs) are large. CONCLUSION Policies decreased deferrals while maintaining safety. A longer observation period would strengthen these observations.

Abstract
BACKGROUND AND OBJECTIVES Several blood services might eventually interview donors with gender-neutral questions on sexual behaviors to improve the inclusivity of blood donation. We tested two ways (i.e., "scenarios") of asking donors about their recent sexual behaviors. MATERIALS AND METHODS The study comprised 126 regular source plasma donors and 102 gay, bisexual, and other men who have sex with men (gbMSM), including 73 cis-gbMSM (i.e., the "cis-gbMSM subgroup," which excluded nonbinary, genderqueer, and trans individuals). In Scenario 1, participants were asked if, in the last 3 months, they "have […] had a new sexual partner or more than one sexual partner." In Scenario 2, they were asked "Have you had a new sexual partner?" and "have you had more than one sexual partner?". Validation questions included more specific questions on the type of partners and sexual activity. RESULTS Among plasma donors, sensitivity was 100.0% for both scenarios; specificity was 100.0% and 99.1% for Scenarios 1 and 2, respectively. Among gbMSM, sensitivity was 74.5% and 82.9% for Scenarios 1 and 2, respectively; specificity was 100.0% for both scenarios. Among cis-gbMSM, sensitivity was 88.6% and 100.0% for Scenarios 1 and 2, respectively; specificity was 100.0% for both scenarios. The area under the receiver operating characteristic curve of Scenario 2 was significantly higher than that of Scenario 1 among gbMSM and in the cis-gbMSM subgroup (all p < .05). CONCLUSION Scenario 2 questions performed well among plasma donors and cis-gbMSM, but less so in the broader gbMSM population.

Abstract
BACKGROUND AND OBJECTIVES The COVID-19 pandemic has brought to the fore how blood services can partner with public health (PH) authorities to inform decisions. Yet the scope of partnerships between blood services and PH authorities is inadequately documented. We explored how blood services partner with PH authorities outside the scope of COVID-19. MATERIALS AND METHODS On 19 January 2022, survey was sent to employees of blood services located throughout the world. Survey questions mainly pertained to partnerships with PH authorities, including how blood specimens are used and collected. RESULTS Twenty-seven recipients-4 (14.8%) in Africa, 3 (11.1%) in Asia, 9 (33.3%) in Europe, 6 (22.2%) in North America, 2 (7.4%) in Oceania and 3 (11.1%) in South America-completed the survey. Fifteen recipients (55.6%) indicated their blood service was directly or indirectly supervised by PH authorities. Twenty-four recipients (88.9%) indicated currently using or planning to use blood donor data or samples for PH research or pathogen surveillance. A substantial proportion of respondents reported using samples or results from non-routine tests for the surveillance of non-transfusion-transmitted infectious disease pathogens (n = 13 [48.1%]); samples or results of non-routine tests for PH research unrelated to pathogens (n = 10 [37.0%]); donor data for PH research unrelated to pathogens (n = 12 [44.4%]) and donor data for PH research unrelated to transfusion safety (n = 11 [40.7%]). Fourteen (51.9%) had established (or planned to establish) longitudinal cohorts and 19 (70.4%) biobanks. CONCLUSION The majority of responding blood services were already involved in or planned to be involved in PH research or pathogen surveillance.

Abstract
Public health crises alter political landscapes. This article investigates social movement strategies during and between the HIV and COVID-19 pandemics. We conducted a set of eighteen in-depth interviews with eleven leaders of organisations working with sex workers, sexual minorities, and transgender people around India, all of whom had been actively involved in HIV prevention programs, before and after the arrival of COVID-19 in India. First HIV, and then COVID-19, altered the political landscape for these groups in relation to three types of institutions: (1) donors (by creating dramatic increases and decreases in the amount, type, and conditions of global funding and deepening inequalities among organisations) (2) the state (by shifting the balance of advocacy and human rights work toward immediate relief); and (3) other social movements (by expanding solidarities across groups but also placing them in competition for limited resources). We argue that, to weather these dramatic shifts, organisations relied on internal alliances and resources built in and after periods of crisis. In this way, despite the differences between the two pandemics, the legacies of HIV shaped the response to COVID-19. Though responses to COVID-19 seem improvised and temporary, they build on a longer-term social movement infrastructure.

Abstract
BACKGROUND Platelets (PLTs) differ in glycolytic activity, resulting in rapid acidification of 'poor' storing PLT concentrates (PCs) in plasma, or depletion of glucose when stored in PLT additive solution (PAS). We aimed to understand why PLT glycolysis rates vary between donors and how this affects storage performance. STUDY DESIGN AND METHODS Buffy coats from donors <45, 45-70 and >70 years were selected and single-donor PCs in plasma or PAS-E were prepared. PCs were stored for 8 days at 22 ± 2°C and sampled regularly for analysis. Mitochondrial activity was analyzed with an Oroboros oxygraph. Age groups, or subgroups divided into quartiles based on glucose consumption, were analyzed with ANOVA. RESULTS In each comparison, PCs of the different groups were not different in volume and cellular composition. PLTs with the highest glucose consumption had a higher initial mean platelet volume (MPV) and developed higher CD62P expression and Annexin A5 binding during storage. Higher glycolytic activity in these PLTs was not a compensation for lower mitochondrial ATP production, because mitochondrial ATP-linked respiration of fresh PLTs correlated positively with MPV (R2 = 0.71). Donors of high glucose-consuming PLTs had more health-related issues. Storage properties of PCs from donors over 70 were not significantly different compared to PCs from donors younger than 45 years. CONCLUSIONS High glucose-consuming PCs developing higher activation levels, not only displayed enhanced mitochondrial activity but were also found to contain larger PLTs, as determined by MPV. Storage performance of PLTs was found to be associated with donor health, but not with donor age.

Abstract
Background The COVID-19 pandemic has affected blood inventory and donation worldwide. The Islamic Republic of Iran was among the first countries to report the COVID-19 pandemic and it faced a significant blood shortage during the first weeks of the pandemic. Aims We aimed to evaluate the impact of COVID-19 pandemic on the number, type, and safety of blood donations, comparing the periods before and during the pandemic. Methods This retrospective study evaluated data from all volunteers who attended the blood transfusion centres in the Islamic Republic of Iran from March to December 2020 (during the COVID-19 pandemic) and during the same period in 2019, i.e. pre-pandemic. Data on the number of blood collections, confirmed transfusion transmissible infection marker test results, and donor demographic information were collected from the Iranian Blood Transfusion Organization integrated donor database. Results Total blood donations decreased by 8.38%. The number of first-time, lapsed, and female blood donors increased by 4.41%, 0.17%, and 0.90% respectively. Regular blood donation decreased by 4.58%. The distribution of the 3 main blood products, red cell concentrate, frozen fresh plasma and platelets, decreased by 7.86%. All changes were statistically significant. The prevalence rates of hepatitis C virus and hepatitis B surface antigen increased significantly during the pandemic. Conclusion COVID-19 had a negative effect on blood safety and availability in the Islamic Republic of Iran. To improve blood supply and enhance regular blood donation, the Iranian Blood Transfusion Organization needs to reassure blood donors of the safety and hygiene measures being observed at blood collection sites.

Philanthropic donor perspectives about providing harm reduction services for people living with HIV/AIDS in a hospital setting. Harm Reduct J 2022; 19:124.

Abstract
BACKGROUND Hospital-based harm reduction services are needed to reduce drug-related harms, facilitate retention in care, and increase medical treatment adherence for people who use drugs. Philanthropic donor support plays a key role in delivering such innovative services which might fall outside current funding streams. However, little is known about how the principles, implementation, and practice of harm reduction services, which are often highly stigmatized, may impact donor behaviours. We explored this issue within Casey House, a speciality hospital in Toronto, Canada. METHODS Our mixed methods study utilized an explanatory sequential design. A convenience sample of n = 106 philanthropic individual donors, recruited via email, completed an anonymous web-based survey, between July and October 2020, which assessed their knowledge of harm reduction services and the potential impact of implementing new hospital-based harm reduction services on donors' future support. Following this, we conducted semi-structured qualitative interviews with n = 12 of the donors who completed a survey and volunteered to be interviewed. Interviews examined donors' perspectives about harm reduction and their hopes/concerns for such programming at Casey House. Data were analysed using descriptive statistics and participatory-based thematic analysis. RESULTS Survey data show a high level of support for hospital-based harm reduction services, with participants reporting that they "strongly agree/agree" with providing harm reduction equipment (85%), supervised consumption services (82%), and prescription opioid treatment (76%) at Casey House. A majority of participants (66%) claimed that implementing new harm reduction services at the hospital would not impact their future donation, while 6% said they would be less inclined to donate. Interview participants were supportive of harm reduction services at Casey House, recognizing the benefits of providing such services for hospital clients and the wider community. However, some spoke of the potential impact that implementing hospital-based harm reduction services may have on "other" donors who might be opposed. Although some believed harm reduction services should be fully funded by the government, most saw a role for donors in supporting such services. CONCLUSIONS Our findings show support of hospital-based harm reduction services among philanthropic donors and provide insight into how donor support may be affected when such services are introduced.
