Differences in microenvironment of lung cancer and pleural effusions by single-cell RNA sequencing. Lung Cancer 2024; 193:107847. [PMID: 38889499 DOI: 10.1016/j.lungcan.2024.107847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2024] [Revised: 05/20/2024] [Accepted: 06/04/2024] [Indexed: 06/20/2024]
Abstract
BACKGROUND Direct comparison of tumor microenvironment of matched lung cancer biopsies and pleural effusions (PE) from the same patients is critical in understanding tumor biology but has not been performed. This is the first study to compare the lung cancer and PE microenvironment by single-cell RNA sequencing (scRNA-seq). METHODS Matched lung cancer biopsies and PE were obtained prospectively from ten patients. We isolated CD45+ cells and performed scRNA-seq to compare the biopsies and PE. RESULTS PE had a higher proportion of CD4+ T cells but lower proportion of CD8+ T cells (False detection rate, FDR = 0.0003) compared to biopsies. There was a higher proportion of naïve CD4+ T cells (FDR = 0.04) and naïve CD8+ T cells (FDR = 0.0008) in PE vs. biopsies. On the other hand, there was a higher proportion of Tregs (FDR = 0.04), effector CD8+ (FDR = 0.006), and exhausted CD8+ T cells (FDR = 0.01) in biopsies. The expression of inflammatory genes in T cells was increased in biopsies vs. PE, including TNF, IFN-ɣ, IL-1R1, IL-1R2, IL-2, IL-12RB2, IL-18R1, and IL-18RAP (FDR = 0.009, 0.013, 0.029, 0.043, 0.009, 0.013, 0.004, and 0.003, respectively). The gene expression of exhaustion markers in T cells was also increased in tumor biopsies including PDCD1, CTLA4, LAG 3, HAVCR2, TIGIT, and CD160 (FDR = 0.008, 0.003, 0.002, 0.011, 0.006, and 0.049, respectively). CONCLUSIONS There is a higher proportion of naïve T cells and lower proportion of exhausted T cells and Tregs in PE compared to lung cancer biopsies, which can be leveraged for prognostic and therapeutic applications.

Local manufacturing processes contribute to variability in human mesenchymal stromal cell expansion while growth media supplements contribute to variability in gene expression and cell function: a Biomedical Excellence for Safer Transfusion (BEST) collaborative study. Cytotherapy 2024; 26:531-539. [PMID: 38043052 DOI: 10.1016/j.jcyt.2023.11.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Accepted: 11/15/2023] [Indexed: 12/04/2023]
Abstract
BACKGROUND AIMS Culture-derived mesenchymal stromal cells (MSCs) exhibit variable characteristics when manufactured using different methods, source material and culture media. The purpose of this multicenter study was to assess the impact on MSC expansion, gene expression and other characteristics when different laboratories expanded MSCs from cultures initiated with bone marrow-MSC aliquots derived from the same donor source material yet with different growth media. METHODS Eight centers expanded MSCs using four human platelet lysate (HPL) and one fetal bovine serum (FBS) products as media supplements. The expanded cells were taken through two passages then assessed for cell count, viability, doubling time, immunophenotype, cell function, immunosuppression and gene expression. Results were analyzed by growth media and by center. RESULTS Center methodologies varied by their local seeding density, feeding regimen, inoculation density, base media and other growth media features (antibiotics, glutamine, serum). Doubling times were more dependent on center than on media supplements. Two centers had appropriate immunophenotyping showing all MSC cultures were positive for CD105, CD73, CD90 and negative for CD34, CD45, CD14, HLA-DR. MSCs cultured in media supplemented with FBS compared with HPL featured greater T-cell inhibition potential. Gene expression analysis showed greater impact of the type of media supplement (HPL versus FBS) than the manufacturing center. Specifically, nine genes were decreased in expression and six increased when combining the four HPL-grown MSCs versus FBS (false discovery rate [FDR] <0.01), however, without significant difference between different sources of HPL (FDR <0.01). CONCLUSIONS Local manufacturing process plays a critical role in MSC expansion while growth media may influence function and gene expression. All HPL and FBS products supported cell growth.

Abstract
BACKGROUND Cord blood units (CBUs) that are ineligible for licensure due to incomplete compliance with FDA recommendations may be used for hematopoietic stem cell transplantation under urgent medical need and an Investigational Drug Application. The largest reason for CBU donor ineligibility is Zika virus (ZIKV) risk. The study's objective was to analyze the impact of current FDA recommendations for ZIKA risk on a large public cord blood bank and propose updated recommendations. METHODS We performed a retrospective analysis of Carolinas Cord Blood Bank (CCBB), an FDA licensed public CBB, using data from January 1, 2016 to November 21, 2023 and compared FDA recommendations for transfusion transmitted infections (TTI) for blood products and relevant communicable disease agents or diseases for human cell, tissue, or cellular or tissue-based products (HCT/Ps). RESULTS CCBB: 9057 (84.3% licensed) CBUs were banked. 984/1682 (58.5%) of unlicensed CBUs had ZIKV risk. 22.0% of CBUs with ZIKV risk were from Hispanic parents, compared to 16.1% of all units. 31 of IND CBUs (11 due to ZIKV risk without reported ZIKV transmission) were safely infused. FDA Guidance: HCT/P ZIKV, HIV, and vCJD recommendations have not been updated since 2018 in contrast to FDA removal of ZIKV as a relevant TTI in 2021 and updating HIV and vCJD guidance related to TTI in 2023 and 2022, respectively. DISCUSSION The FDA should consider new data to revise the HCT/P donor eligibility recommendations, which will increase the number of eligible HCT/P donors, and potentially improve access to therapies for a more diverse patient population.

Abstract
Haemorrhagic shock is frequent in critical care settings and responsible for a high mortality rate due to multiple organ dysfunction and coagulopathy. The management of critically ill patients with bleeding and shock is complex, and treatment of these patients must be rapid and definitive. The administration of large volumes of blood components leads to major physiological alterations which must be mitigated during and after bleeding. Early recognition of bleeding and coagulopathy, understanding the underlying pathophysiology related to specific disease states, and the development of individualised management protocols are important for optimal outcomes. This review describes the contemporary understanding of the pathophysiology of various types of coagulopathic bleeding; the diagnosis and management of critically ill bleeding patients, including major haemorrhage protocols and post-transfusion management; and finally highlights recent areas of opportunity to better understand optimal management strategies for managing bleeding in the intensive care unit (ICU).

Abstract
Abstract
Glioblastoma is the most prevalent primary brain malignancy, with a median survival of less than 21 months despite treatment with surgery, radiation, and chemotherapy. Significant intra-tumoral heterogeneity, combined with the immunosuppressive micro-environment and the limited immune population present within the privileged CNS has resulted in the failure of immunotherapy approaches. We seek to address these challenges by isolating Tumor Infiltrating Lymphocytes (TILs) which are already neoantigen specific and expanding them ex vivo before re-administering them to the patient. This allows us to greatly increase the available pool of T cells which are specific for a diversity of tumor neoantigens in the patient, while also reversing exhaustion by the addition of stimulatory co-culturing agents. We report the successful expansion of glioblastoma associated TILs from both surgically resected tumors (5 of 7 samples, 71%) and liquid aspirate from the surgical field collected in Lukens traps (4 of 6 samples, 66%). TILs were expanded with high-dose IL2 initially in the presence of tumor digest (PreREP) followed by activation and expansion with CD3/CD28 nanobeads (REP). Flow cytometry performed on PreREP TILs revealed that 50-90% of the population consisted of effector memory T cells (CCR7-CD45RA-) with 5-40% consisting of central memory T cells (CCR7+CD45RA-). The addition of stimulatory agents such as anti-4-1BB (Urelumab) during the PreREP phase increased cell yields, as well as skewing the population towards a non-exhausted CD8+ phenotype (reduced expression of PD1, LAG3, TIM3). These cells have demonstrated tumor antigen specific activation based on IFNγ and TNFα secretion following stimulation with autologous tumor digests and patient matched neurosphere cultures. TIL expansion with Urelumab doubled CD8% in the product (16% to 31%) and reduced CD4% (78% to 65%). Expanded TILs had more potent cytotoxic CD8+ T cells responses characterized by significantly increased numbers of tumor antigen specific IFNγ+ (std: 1000, Ure: 6000) and TNFα+ (std:2000, Ure:20,000))cells compared to traditionally expanded TILs. We have demonstrated that TIL isolation from resected clinical glioma is feasible and can generate large quantities of immune cells whose functional status can be altered by the addition of stimulatory agents. And most importantly these TILs are reactive and specific for tumor antigens. Following additional assessment of in vitro cytotoxicity against matched tumor neurospheres in vitro we will evaluate safety and feasibility of our novel TIL approach in patients with glioblastoma.

Abstract
BACKGROUND Treatment options for patients with COVID-19-related acute respiratory distress syndrome (ARDS) are desperately needed. Allogeneic human umbilical cord derived mesenchymal stromal cells (hCT-MSCs) have potential therapeutic benefits in these critically ill patients, but feasibility and safety data are lacking. MATERIALS AND METHODS In this phase I multisite study, 10 patients with COVID-19-related ARDS were treated with 3 daily intravenous infusions of hCT-MSCs (1 million cells/kg, maximum dose 100 million cells). The primary endpoint assessed safety. RESULTS Ten patients (7 females, 3 males; median age 62 years (range 39-79)) were enrolled at 2 sites and received a total of 30 doses of study product. The average cell dose was 0.93 cells/kg (range 0.56-1.45 cells/kg and total dose range 55-117 million cells) with 5/30 (17%) of doses lower than intended dose. Average cell viability was 85% (range 63%-99%) with all but one meeting the >70% release criteria. There were no infusion-related reactions or study-related adverse events, 28 non-serious adverse events in 3 unique patients, and 2 serious adverse events in 2 unique patients, which were expected and unrelated to the study product. Five patients died: 3 by day 28 and 5 by day 90 of the study (median 27 days, range 7-76 days). All deaths were determined to be unrelated to the hCT-MSCs. CONCLUSION We were able to collect relevant safety outcomes for the use of hCT-MSCs in patients with COVID-19-related ARDS. Future studies to explore their safety and efficacy are warranted.

Abstract
Although altruistic regular blood donors are vital for the blood supply, many become iron deficient from donation-induced iron loss. The effects of blood donation-induced iron deficiency on red cell transfusion quality or donor cognition are unknown. In this double-blind, randomized trial, adult iron-deficient blood donors (n = 79; ferritin < 15 μg/L and zinc protoporphyrin >60 μMol/mol heme) who met donation qualifications were enrolled. A first standard blood donation was followed by the gold-standard measure for red cell storage quality: a 51-chromium posttransfusion red cell recovery study. Donors were then randomized to intravenous iron repletion (1 g low-molecular-weight iron dextran) or placebo. A second donation ∼5 months later was followed by another recovery study. Primary outcome was the within-subject change in posttransfusion recovery. The primary outcome measure of an ancillary study reported here was the National Institutes of Health Toolbox-derived uncorrected standard Cognition Fluid Composite Score. Overall, 983 donors were screened; 110 were iron-deficient, and of these, 39 were randomized to iron repletion and 40 to placebo. Red cell storage quality was unchanged by iron repletion: mean change in posttransfusion recovery was 1.6% (95% confidence interval -0.5 to 3.8) and -0.4% (-2.0 to 1.2) with and without iron, respectively. Iron repletion did not affect any cognition or well-being measures. These data provide evidence that current criteria for blood donation preserve red cell transfusion quality for the recipient and protect adult donors from measurable effects of blood donation-induced iron deficiency on cognition. This trial was registered at www.clinicaltrials.gov as NCT02889133 and NCT02990559.

Abstract
The platelet collection and distribution system, based on volunteer nonremunerated donors, apheresis platelet collections, and primarily 1-directional distribution of platelets for up to 5-day room temperature storage at hospitals, typically performs well and provides therapeutic support for hundreds of thousands of patients annually. However, direct and indirect effects of the coronavirus disease 2019 pandemic, particularly during the Omicron wave, produced dramatic systemic failures and severe shortages. We propose 4 initiatives to reinforce the existing platelet pipeline and buffer the platelet supply against future unexpected disruptions.

Abstract
BACKGROUND A greater understanding of young, first-time donor motivators and barriers is needed to address the ongoing challenge of retaining these essential donors. STUDY DESIGN AND METHODS Structured interviews conducted with 508 young, first-time whole blood donors [66.1% female; Mean Age = 19.4 (SD = 2.5) years] were coded to identify reported motivators and barriers. Reported motivators and barriers were then examined for their association with attempted donation behavior over a 14-month follow-up, and for potential sex, race, and ethnic group differences in the frequency of endorsement. RESULTS Prosocial motivation (e.g., altruism) was the most commonly reported motivator and fear (e.g., fainting, needles) was the most commonly reported barrier. Donation behavior was unrelated to reported motivators, but was significantly related to four reported barriers including fear of fainting/dizziness, fear of needles/pain, having personal commitments that conflict with donating, and perceiving oneself as unsuited to donate for health reasons. Sex, racial, and ethnic differences were noted with respect to the percentages of donors reporting several donation-related motivators and barriers. CONCLUSION The present findings identify donation-related barriers that could be important targets to address in the effort to encourage new young donors and to retain these new donors for the long term. Importantly, these data also highlight the importance of considering individual differences in donor motivation as a function of sex, race, and ethnicity.

Abstract
DESCRIPTION Coronavirus disease 2019 convalescent plasma (CCP) has emerged as a potential treatment of COVID-19. However, meta-analysis data and recommendations are limited. The Association for the Advancement of Blood and Biotherapies (AABB) developed clinical practice guidelines for the appropriate use of CCP. METHODS These guidelines are based on 2 living systematic reviews of randomized controlled trials (RCTs) evaluating CCP from 1 January 2019 to 26 January 2022. There were 33 RCTs assessing 21 916 participants. The results were summarized using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) method. An expert panel reviewed the data using the GRADE framework to formulate recommendations. RECOMMENDATION 1 (OUTPATIENT) The AABB suggests CCP transfusion in addition to the usual standard of care for outpatients with COVID-19 who are at high risk for disease progression (weak recommendation, moderate-certainty evidence). RECOMMENDATION 2 (INPATIENT) The AABB recommends against CCP transfusion for unselected hospitalized persons with moderate or severe disease (strong recommendation, high-certainty evidence). This recommendation does not apply to immunosuppressed patients or those who lack antibodies against SARS-CoV-2. RECOMMENDATION 3 (INPATIENT) The AABB suggests CCP transfusion in addition to the usual standard of care for hospitalized patients with COVID-19 who do not have SARS-CoV-2 antibodies detected at admission (weak recommendation, low-certainty evidence). RECOMMENDATION 4 (INPATIENT) The AABB suggests CCP transfusion in addition to the usual standard of care for hospitalized patients with COVID-19 and preexisting immunosuppression (weak recommendation, low-certainty evidence). RECOMMENDATION 5 (PROPHYLAXIS) The AABB suggests against prophylactic CCP transfusion for uninfected persons with close contact exposure to a person with COVID-19 (weak recommendation, low-certainty evidence). GOOD CLINICAL PRACTICE STATEMENT CCP is most effective when transfused with high neutralizing titers to infected patients early after symptom onset.

Abstract
BACKGROUND The United States (US) Expanded Access Program (EAP) to coronavirus disease 2019 (COVID-19) convalescent plasma was initiated in response to the rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of COVID-19. While randomized clinical trials were in various stages of development and enrollment, there was an urgent need for widespread access to potential therapeutic agents. The objective of this study is to report on the demographic, geographical, and chronological characteristics of patients in the EAP, and key safety metrics following transfusion of COVID-19 convalescent plasma. METHODS AND FINDINGS Mayo Clinic served as the central institutional review board for all participating facilities, and any US physician could participate as a local physician-principal investigator. Eligible patients were hospitalized, were aged 18 years or older, and had-or were at risk of progression to-severe or life-threatening COVID-19; eligible patients were enrolled through the EAP central website. Blood collection facilities rapidly implemented programs to collect convalescent plasma for hospitalized patients with COVID-19. Demographic and clinical characteristics of all enrolled patients in the EAP were summarized. Temporal patterns in access to COVID-19 convalescent plasma were investigated by comparing daily and weekly changes in EAP enrollment in response to changes in infection rate at the state level. Geographical analyses on access to convalescent plasma included assessing EAP enrollment in all national hospital referral regions, as well as assessing enrollment in metropolitan areas and less populated areas that did not have access to COVID-19 clinical trials. From April 3 to August 23, 2020, 105,717 hospitalized patients with severe or life-threatening COVID-19 were enrolled in the EAP. The majority of patients were 60 years of age or older (57.8%), were male (58.4%), and had overweight or obesity (83.8%). There was substantial inclusion of minorities and underserved populations: 46.4% of patients were of a race other than white, and 37.2% of patients were of Hispanic ethnicity. Chronologically and geographically, increases in the number of both enrollments and transfusions in the EAP closely followed confirmed infections across all 50 states. Nearly all national hospital referral regions enrolled and transfused patients in the EAP, including both in metropolitan and in less populated areas. The incidence of serious adverse events was objectively low (<1%), and the overall crude 30-day mortality rate was 25.2% (95% CI, 25.0% to 25.5%). This registry study was limited by the observational and pragmatic study design that did not include a control or comparator group; thus, the data should not be used to infer definitive treatment effects. CONCLUSIONS These results suggest that the EAP provided widespread access to COVID-19 convalescent plasma in all 50 states, including for underserved racial and ethnic minority populations. The study design of the EAP may serve as a model for future efforts when broad access to a treatment is needed in response to an emerging infectious disease.

[PMID: 34605554 DOI: 10.1111/trf.16694] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 09/24/2021] [Accepted: 09/24/2021] [Indexed: 01/14/2023]
Abstract
BACKGROUND The potential for iron deficiency is a known blood donor health concern and suggests the need to inform donors about the potential risks of low iron levels as well as strategies to address these risks. STUDY DESIGN AND METHODS Frequent (n = 904) and young (n = 629) donors were randomly assigned within risk group to either a control (n = 548) or an intervention (n = 985) group. The control group answered questions at baseline and 6-month follow-up regarding their awareness of the risk of donation-related iron depletion and whether they were taking actions to address their iron status. The intervention group answered the same questions at baseline and follow-up, but after completing the baseline survey, they received information regarding their risk of iron depletion and behaviors they could adopt to mitigate this risk. Intervention group participants were also offered the opportunity to develop an action plan to help them supplement their iron intake. RESULTS The intervention enhanced overall awareness of donation-related iron loss (OR = 1.5, 95% CI 1.171-1.864, p = .001), with no negative impact on retention. Reported iron health behaviors (iron supplementation, speaking with a doctor) showed significant increases when action planning was paired with the educational information. CONCLUSION These findings suggest that it is possible to increase awareness of donation-related risk for iron depletion without negatively influencing retention, and combining education with encouragement to develop an action plan may increase the likelihood of both retention and behavioral changes to promote healthy iron levels.

Fear is associated with attrition of first-time whole blood donors: A longitudinal examination of donor confidence and attitude as potential mediators. Transfusion 2021; 61:3372-3380. [PMID: 34535897 DOI: 10.1111/trf.16671] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 09/10/2021] [Accepted: 09/10/2021] [Indexed: 01/02/2023]
Abstract
BACKGROUND Elevated fear and anxiety regarding donation-related stimuli (e.g., needles, pain, blood, fainting) has been associated with reduced blood donor recruitment and retention. The present longitudinal study tests the notion that this inverse relationship may be accounted for by lower donation confidence and more negative donation attitudes among fearful first-time donors. STUDY DESIGN AND METHODS In a sample of 1479 first-time whole blood donors [67.9% female; mean age = 19.3 (standard deviation (SD) = 2.5) years], path analyses were conducted to examine relationships among donor ratings of fear of blood draw and donation anxiety obtained approximately 1 week after donation, donation confidence and attitudes assessed approximately 6 weeks later, and donation attempts over the 14 months following the original donation. RESULTS Path analyses indicated that both fear of blood draws and donation anxiety were associated with fewer attempted donations, and that these effects were indirectly mediated by a combination of lower donor confidence and more negative donation attitudes. CONCLUSION Because retention of new blood donors is essential to maintain a healthy blood supply, the results of the present study suggest that first-time donors should be assessed for fear and anxiety so that appropriate strategies can be provided to address their concerns, bolster their confidence and attitudes, and ultimately promote their long-term retention.

Results from the blood donor competence, autonomy, and relatedness enhancement (blood donor CARE) randomized trial. Transfusion 2021; 61:2637-2649. [PMID: 34224590 DOI: 10.1111/trf.16577] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 06/17/2021] [Accepted: 06/17/2021] [Indexed: 12/22/2022]
Abstract
BACKGROUND This study aimed to promote competence, autonomy, and relatedness among first-time whole blood donors to enhance intrinsic motivation and increase retention. STUDY DESIGN AND METHODS Using a full factorial design, first-time donors (N = 2002) were randomly assigned to a no-treatment control condition or to one of seven intervention conditions designed to promote donation competence, autonomy, relatedness, a combination of two (e.g., competence and autonomy), or all three constructs. Participants completed donor motivation measures before the intervention and 6 weeks later, and subsequent donation attempts were assessed for 1 year. RESULTS There was no significant group difference in the frequency of donation attempts or in the number of days to return. Significant effects of group were observed for 10 of the 12 motivation measures, although follow-up analyses revealed significant differences from the control group were restricted to interventions that included an autonomy component. Path analyses confirmed direct associations between interventions involving autonomy and donor motivation, and indirect mediation of donation attempts via stronger donation intentions and lower donation anxiety. CONCLUSION Among young, first-time, whole blood donors, brief interventions that include support for donor autonomy were associated with direct effects on donor motivation and indirect, but small, effects on subsequent donation behavior.

Abstract
BACKGROUND The United States (US) leads all high-income countries in gunshot wound (GSW) deaths. However, previous US studies have not evaluated the national blood transfusion utilization patterns in hospitalized GSW patients. METHODS Data from 2016 to 2017 were analyzed from the Nationwide Emergency Department Sample (NEDS) and Nationwide Inpatient Sample (NIS), the largest all-payer emergency department (ED) and inpatient databases, respectively. Using stratified probability sampling, weights were applied to generate nationally representative estimates. Multivariable Poisson-regression models were used to estimate prevalence ratios (PR) of blood transfusion. RESULTS There were 168,315 ED visits and 58,815 hospitalizations (age = 18-90 years) following a GSW. The majority of hospitalizations were men (88.5%), age 18-24 years (31.8%), and assault-related GSW (51.3%). Blacks had the largest proportion (48.7%) overall of all GSW hospitalizations; Whites accounted for the highest proportion of intentional self-harm injuries (72.4%). Blood transfusions occurred in 12.7% of hospitalizations (12.0% red blood cell [RBC], 4.9% plasma, and 2.5% platelet transfusions). Only 1.9% of cases were associated with transfusion of all three blood components. Hospitalizations with major/extreme severity of illness had significantly higher prevalence of transfusion versus those with mild/moderate severity [crude PR = 4.79 (95%CI:4.15-5.33, p < .001)]. Overall, 8.2% of hospitalizations with GSW died, of whom 26.8% required blood transfusions, which was significantly higher than survivors [crude PR = 2.34 (95%CI:2.10-2.61, p < .001)]. The vast majority (95%) of the transfusions among those who died were within 48 h since admission. CONCLUSIONS Gun-related violence is a public health emergency in the US, and GSWs are a source of significant mortality, blood utilization, and health care costs.

Abstract
BACKGROUND Convalescent plasma (CP) for treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has shown preliminary signs of effectiveness in moderate to severely ill patients in reducing mortality. While studies have demonstrated a low risk of serious adverse events, the comprehensive incidence and nature of the spectrum of transfusion reactions to CP is unknown. We retrospectively examined 427 adult inpatient CP transfusions to determine incidence and types of reactions, as well as clinical parameters and risk factors associated with transfusion reactions. STUDY DESIGN AND METHODS Retrospective analysis was performed for 427 transfusions to 215 adult patients with coronavirus 2019 (COVID-19) within the Mount Sinai Health System, through the US Food and Drug Administration emergency investigational new drug and the Mayo Clinic Expanded Access Protocol to Convalescent Plasma approval pathways. Transfusions were blindly evaluated by two reviewers and adjudicated by a third reviewer in discordant cases. Patient demographics and clinical and laboratory parameters were compared and analyzed. RESULTS Fifty-five reactions from 427 transfusions were identified (12.9% incidence), and 13 were attributed to transfusion (3.1% incidence). Reactions were classified as underlying COVID-19 (76%), febrile nonhemolytic (10.9%), transfusion-associated circulatory overload (9.1%), and allergic (1.8%) and hypotensive (1.8%) reactions. Statistical analysis identified increased transfusion reaction risk for ABO blood group B or Sequential Organ Failure Assessment scores of 12 to 13, and decreased risk within the age group of 80 to 89 years. CONCLUSION Our findings support the use of CP as a safe, therapeutic option from a transfusion reaction perspective, in the setting of COVID-19. Further studies are needed to confirm the clinical significance of ABO group B, age, and predisposing disease severity in the incidence of transfusion reaction events.

Examination of the relationship between iron status and cognitive function among healthy young women with and without a recent history of blood donation. Transfusion 2020; 60:2886-2895.

Abstract
BACKGROUND With growing awareness of the prevalence of nonanemic iron deficiency among blood donors, there is a need to explore the extent of potential negative consequences. This study examined the relationship between various measures of iron status, blood donation history, and neuropsychological and psychosocial functioning in healthy young women. STUDY DESIGN AND METHODS Using a cross-sectional design, 160 female undergraduates completed neuropsychology tests and measures of sleep, fatigue, quality of life, and depression before providing a blood sample. Correlational analyses examined the relationship between iron status (ferritin, iron, hemoglobin, and zinc protoporphyrin) and cognitive and psychosocial functioning. Performance on these measures was also examined as a function of recent blood donation history (zero, one, more than one donation in the past year). RESULTS Iron status (low ferritin, iron, or hemoglobin or high zinc protoporphyrin) was not associated with poorer performance on the cognitive tasks. Further, participants who reported donating once in the previous year performed better, rather than worse, than those with no recent donation history on several measures of executive function, even when controlling for ferritin levels. Although there was some evidence of greater fatigue among those who had donated more than once in the past year, this effect was not accounted for by ferritin levels. CONCLUSION The present findings are consistent with prior evidence that nonanemic iron deficiency is not associated with cognitive impairment or psychosocial dysfunction in healthy young females. Because these results are based on cross-sectional evidence, further study using longitudinal research is needed to confirm these findings.

Abstract
Objective COVID19 has caused a global and ongoing pandemic. The need for population seroconversion data is apparent to monitor and respond to the pandemic. Using a lateral flow assay (LFA) testing platform, the seropositivity in 63 New York Blood Center (NYBC) Convelescent Plasma (CP) donor samples were evaluated for the presence of COVID19 specific IgG and IgM. Results CP donors showed diverse antibody result. Convalescent donor plasma contains SARS-CoV-2 specific antibodies. Weak antibody bands may identify low titer CP donors. LFA tests can identify antibody positive individuals that have recovered from COVID19. Confirming suspected cases using antibody detection could help inform the patient and the community as to the relative risk to future exposure and a better understanding of disease exposure.

Use of a rapid electronic survey methodology to estimate blood donors' potential exposure to emerging infectious diseases: Application of a statistically representative sampling methodology to assess risk in US blood centers. Transfusion 2020; 60:1987-1997.

Abstract
Risk assessments of transfusion-transmitted emerging infectious diseases (EIDs) are complicated by the fact that blood donors' demographics and behaviors can be different from the general population. Therefore, when assessing potential blood donor exposure to EIDs, the use of general population characteristics, such as U.S. travel statistics, may invoke uncertainties that result in inaccurate estimates of blood donor exposure. This may, in turn, lead to the creation of donor deferral policies that do not match actual risk. STUDY DESIGN AND METHODS This article reports on the development of a system to rapidly assess EID risks for a nationally representative portion of the U.S. blood donor population. To assess the effectiveness of this system, a test survey was developed and deployed to a statistically representative sample frame of blood donors from five blood collecting organizations. Donors were directed to an online survey to ascertain their recent travel and potential exposure to Middle East respiratory syndrome coronavirus (MERS-CoV). RESULTS A total of 7128 responses were received from 54 256 invitations. The age-adjusted estimated total number of blood donors potentially exposed to MERS-CoV was approximately 15 640 blood donors compared to a lower U.S. general population-based estimate of 9610 blood donors. CONCLUSION The structured donor demographic sample-based data provided an assessment of blood donors' potential exposure to an emerging pathogen that was 63% larger than the U.S. population-based estimate. This illustrates the need for tailored blood donor-based EID risk assessments that provide more specific demographic risk intelligence and can inform appropriate regulatory decision making.

Abstract
Since the beginning of the COVID-19 pandemic, the use of convalescent plasma as a possible treatment has been explored. Here we describe our experience as the first U.S. organization creating a COVID-19 convalescent plasma program to support its use through the single-patient emergency investigational new drug, the National Expanded Access Program, and multiple randomized controlled trials. Within weeks, we were able to distribute more than 8000 products, scale up collections to more than 4000 units per week, meet hospital demand, and support randomized controlled trials to evaluate the efficacy of convalescent plasma treatment. This was through strategic planning; redeployment of staff; and active engagement of hospital, community, and public health partners. Our partners helped with donor recruitment, testing, patient advocacy, and patient availability. The program will continue to evolve as we learn more about optimizing the product. Remaining issues to be resolved are antibody titers, dose, and at what stage of disease to transfuse.
