- Abstract
Abstract: The past century has seen many advances in the field of resuscitation. This is particularly true in the subset of patients who sustain major injuries causing hemorrhagic shock (HS) and require massive transfusion of more than 10 U of blood within the first 24 hours. Controversies on how best to resuscitate these patients include the role of fresh whole blood, stored whole blood, fresh frozen plasma, platelets, colloid solutions, balanced electrolytes solution, vasopressors, and diuretics. This review summarizes the often-contradictory recommendations observed and studied by a single trauma surgeon working in a busy urban acute care center for 65 years., Level of Evidence: Level I., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Abstract: Whole blood can be ABO-type specific (type-specific whole blood (TSWB)) or low-titer O universal donor (low-titer O whole blood (LTOWB)). Having previously used LTOWB, the US Armed Forces Blood Program began using TSWB in 1965 as a method of increasing the donor pool. In contrast to military practice, the Association for the Advancement of Blood and Biotherapies formerly the American association of blood banks (AABB), from its first guidelines in 1958 until 2018, permitted only TSWB. Attempting to reduce time to transfusion, the US military reintroduced LTOWB in the deployed environment in 2015; this practice was endorsed by the AABB in 2018 and is progressively being implemented by military and civilian providers worldwide. Low-titer O whole blood is the only practical solution prehospital. However, there are several reasons to retain the option of TSWB in hospitals with a laboratory. These include (1) as-yet ill-defined risks of immunological complications from ABO-incompatible plasma (even when this has low titers of anti-A and -B), (2) risks of high volumes of LTOWB including published historical advice (based on clinical experience) not to transfuse type-specific blood for 2 to 3 weeks following a substantial LTOWB transfusion, (3) uncertainty as to the optimal definition of "low titer," and (4) expanding the potential donor pool by allowing type-specific transfusion. Several large randomized controlled trials currently underway are comparing LTOWB with component therapy, but none address the question of LTOWB versus TSWB. There are sufficient data to suggest that the additional risks of transfusing LTOWB to non-group O recipients should be avoided by using TSWB as soon as possible. Combined with the advantage of maintaining an adequate supply of blood products in times of high demand, this suggests that retaining TSWB within the civilian and military blood supply system is desirable. TSWB should be preferred when patient blood group is confirmed in facilities with a hematology laboratory, with LTOWB reserved for patients whose blood group is unknown., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
Objectives: The aims of this study were to assess the impact of the closed-loop sampling method on blood loss and the need for blood transfusion in pediatric patients following cardiac surgery., Design: Retrospective observational study., Setting: A single tertiary center., Participants: All pediatric patients younger than 4 years old who were admitted to the pediatric intensive care unit (PICU) after cardiac surgery were enrolled. The study included 100 pediatric patients in the conservative (postimplementation) group and 43 pediatric patients in the nonconservative group (preimplementation)., Interventions: Observational., Measurements: The primary outcome was the volume of blood loss during the PICU follow-up period. The secondary outcomes were the requirement for blood transfusion in each group, duration of mechanical ventilation, length of intensive care unit (ICU) stay, length of hospital stay, and mortality., Main Results: In the conservative (postimplementation) group, blood loss during the follow-up period was 0.67 (0.33-1.16) mL/kg/d, while it was 0.95 (0.50-2.30) mL/kg/d in the nonconservative (preimplementation) group, demonstrating a significant reduction in blood loss in the conservative group (p = 0.012). The groups showed no significant differences in terms of the required blood transfusion volume postoperatively during the first 24 hours, first 48 hours, or after 48 hours (p = 0.061, 0.536, 0.442, respectively). The frequency of blood transfusion was comparable between the groups during the first 24 hours, first 48 hours, or after 48 hours postoperatively (p = 0.277, 0.639, 0.075, respectively). In addition, the groups did not show significant differences in the duration of mechanical ventilation, length of ICU stay, length of hospital stay, or mortality., Conclusions: The closed-loop sampling method can be efficient in decreasing blood loss during postoperative PICU follow-up for pediatric patients after cardiac surgeries. However, its application did not reduce the frequency or the volume of blood transfusion in these patients., Competing Interests: Declaration of competing interest All authors confirm that this study was self-funded.

- Abstract
Few data describe pediatric patients who receive massive transfusion for life-threatening hemorrhage (LTH) while on extracorporeal membrane oxygenation (ECMO). We present a retrospective secondary analysis of a multicenter prospective observational study to describe resource utilization and mortality in pediatric patients with LTH while on ECMO. Children who were on ECMO during an LTH were compared to children with LTH who were not on ECMO. Primary outcomes were volumes of blood products administered and 28 day mortality. Comparisons were assessed by two-sided Fisher's exact test or Wilcoxon rank sum test. A total of 449 children, including 36 on ECMO, were included. Compared to those not on ECMO, children on ECMO received a higher volume of blood products (110 [50-223] vs . 59 [28-113]) ml/kg, p = 0.002) and were more likely to receive antifibrinolytic therapy (39% vs . 10%, p < 0.001). Blood product ratios were similar. Extracorporeal membrane oxygenation patients had higher 28 day mortality (64% vs. 35%, p = 0.001), although 24 hour mortality was similar (17% vs . 23%, p = 0.5). In conclusion, children on ECMO with LTH experience high resource utilization and 28 day mortality. Studies are needed to identify children at risk for LTH and to evaluate ECMO-specific treatment strategies., Competing Interests: Disclosure: M.E.S. is a consultant for Medtronic education services; P.C.S. is a consultant for Cerus, Hemanext, CSL Behring, and Haima and is founder and chief medical officer for Kalocyte.

- Abstract
Objectives: To estimate whether the association of transfusion and acute kidney injury (AKI) has a threshold of oxygen delivery below which transfusion is beneficial but above which it is harmful., Design: Retrospective study SETTING: Cardiovascular operating room and intensive care unit PARTICIPANTS: Patients undergoing cardiac surgery with continuous oxygen delivery monitoring during cardiopulmonary bypass INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: Logistic regression was used to estimate the associations between oxygen delivery (mean, cumulative deficit, and bands of oxygen delivery), transfusion, and their interaction and AKI. A subgroup analysis of transfused and nontransfused patients with exact matching on cumulative oxygen deficit and time on bypass with adjustment for propensity to receive a transfusion using logistic regression. Nine hundred ninety-one of 4,203 patients developed AKI within 7 days. After adjustment for confounders, lower mean oxygen delivery (odds ratio [OR], 0.968; 95% confidence interval [CI], 0.949-0.988; p = 0.002) and transfusions (OR, 1.442; 95% CI, 1.077, 1.932; p = 0.014) were associated with increased odds of AKI by 7 days. As oxygen delivery decreased, the risk of AKI increased, with the slope of the OR steeper at <160 mL/m
2 /min. In the subgroup analysis, matched transfused patients were more likely than matched nontransfused patients to develop AKI (45% [n = 145] v 31% [n = 101]; p < 0.001). However, after propensity score adjustment, the difference was nonsignificant (OR, 1.181; 95% CI, 0.796-1.752; p = 0.406)., Conclusions: We found a nonlinear relationship between oxygen delivery and AKI. We found no level of oxygen delivery at which transfusion was associated with a decreased risk of AKI., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

- Abstract
Introduction: Whole blood (WB) resuscitation has reemerged as a resuscitation strategy for injured patients. However, the effect of WB-based resuscitation on outcomes has not been established. The primary objective of this guideline was to develop evidence-based recommendations on whether WB should be considered in civilian trauma patients receiving blood transfusions., Methods: An Eastern Association for the Surgery of Trauma working group performed a systematic review and meta-analysis using the Grading of Recommendations Assessment, Development and Evaluation methodology. One Population, Intervention, Comparison, and Outcomes question was developed to analyze the effect of WB resuscitation in the acute phase on mortality, transfusion requirements, infectious complications, and intensive care unit length of stay. English language studies including adult civilian trauma patients comparing in-hospital WB to component therapy were included. Medline, Embase, Cochrane CENTRAL, CINAHL Plus, and Web of Science were queried. GRADEpro (McMaster University; Evidence Prime, Inc.; Ontario) was used to assess quality of evidence and risk of bias. The study was registered on International Prospective Register of Systematic Reviews (CRD42023451143)., Results: A total of 21 studies were included. Most patients were severely injured and required blood transfusion, massive transfusion protocol activation, and/or a hemorrhage control procedure in the early phase of resuscitation. Mortality was assessed separately at the following intervals: early (i.e., emergency department, 3 hours, or 6 hours), 24 hours, late (i.e., 28 days or 30 days), and in-hospital. On meta-analysis, WB was not associated with decreased mortality. Whole blood was associated with decreased 4-hour red blood cell (mean difference, -1.82; 95% confidence interval [CI], -3.12 to -0.52), 4-hour plasma (mean difference, -1.47; 95% CI, -2.94 to 0), and 24-hour red blood cell transfusions (mean difference, -1.22; 95% CI, -2.24 to -0.19) compared with component therapy. There were no differences in infectious complications or intensive care unit length of stay between groups., Conclusion: We conditionally recommend WB resuscitation in adult civilian trauma patients receiving blood transfusions, recognizing that data are limited for certain populations, including women of childbearing age, and therefore this guideline may not apply to these populations., Level of Evidence: Systematic Review/Meta-Analysis; Level III., (Copyright © 2024 Wolters Kluwer Health, Inc.

- Abstract
In expeditionary environments, the consistent availability of blood for casualty care is imperative yet challenging. Responding to evidence and the specific needs of its expeditionary context, the US Central Command (USCENTCOM) prioritized supplying stored low titer O whole blood (LTOWB) to its units from March, 2023 onward. A strategy was devised to set minimal LTOWB on-hand supply benchmarks, determined by the number of operating beds and point of injury teams. This transition led to a 54% reduction in orders for packed red blood cells. As a countermove, the Armed Services Blood Program (ASBP) enhanced LTOWB production at a conversion rate 2:1 from packed red blood cell to LTOWB. Consequently, there was a decline in expired blood products, and fulfillment rates for blood requests are projected to reach 100% consistently. This paper delves into the intricacies of the expeditionary blood supply, the rationale behind the LTOWB transition, the devised allocation strategy, and the subsequent impacts of this change., (Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2024.

- Abstract
Introduction: Providing resilient Damage Control Resuscitation capabilities as close to the point of injury as possible is paramount to reducing mortality and improving patient outcomes for our nation's warfighters. Emergency Fresh Whole Blood Transfusions (EFWBT) play a critical role in supporting this capability, especially in future large-scale combat operations against peer adversaries with expected large patient volumes, restrictive operating environments, and unreliable logistical supply lines. Although there are service-specific training programs for whole blood transfusion, there is currently no dedicated EFWBT training for future military medical officers. To address this gap, we developed, implemented, and evaluated a training program to enhance EFWBT proficiency in third-year military medical students at the F. Edward Hebert School of Medicine at the USU., Materials and Methods: After reviewing both the 75th Ranger Regiment Ranger O-Low Titer program and the Marine Corps' Valkyrie program, along with the relevant Joint Trauma System Clinical Practice Guidelines, we created a streamlined and abbreviated training curriculum. The training consisted of both online preparatory materials as well as a 2-hour in-person training that included didactic and experiential learning components. Participants were 165 active duty third-year medical students at USU. Participants were assessed using a pre- and post-assessment self-reported questionnaire on their confidence in the practical application and administrative oversight requirements of an EFWBT program. Participants' performance was also assessed using a pre/post knowledge assessment consisting of 10 multiple choice questions identified as critical to understanding of the academic principles of EFWBT along with the baseline questionnaire., Results: Differences in the mean scores of the pre- and post-assessment self-reported questionnaire (increased from 2.32 to 3.95) were statistically significant (P < .001). Similarly, there was a statistically significant improvement in student test scores, with the mean score increasing by approximately 3 points or 30%. There was no significant difference in student confidence assessment or test scores based on branch of service. Students who had previously deployed did not show a statistically significant difference in scores compared to students who had not previously deployed., Conclusions: Our results suggest that the implementation of streamlined EFWBT training into the undergraduate medical education of future military medical officers offers an efficient way to improve their baseline proficiency in EFWBTs. Future research is needed to assess the impact of this training on real-world applications in forward-deployed environments., (© The Association of Military Surgeons of the United States 2024.

- Abstract
The growing world population and increasing life expectancy are driving the need to improve the quality of blood transfusion, organ transplantation, and preservation. Here, to improve the ability of red blood cells (RBCs) for normothermic machine perfusion, a biocompatible blood silicification approach termed "shielding-augmenting RBC-in-nanoscale amorphous silica (SARNAS)" has been developed. The key to RBC surface engineering and structure augmentation is the precise control of the hydrolysis form of silicic acid to realize stabilization of RBC within conformal nanoscale silica-based exoskeletons. The formed silicified RBCs (Si-RBCs) maintain membrane/structural integrity, normal cellular functions (e.g., metabolism, oxygen-carrying capability), and enhance resistance to external stressors as well as tunable mechanical properties, resulting in nearly 100% RBC cryoprotection. In vivo experiments confirm their excellent biocompatibility. By shielding RBC surface antigens, the Si-RBCs provide universal blood compatibility, the ability for allogeneic mechanical perfusion, and more importantly, the possibility for cross-species transfusion. Being simple, reliable, and easily scalable, the SARNAS strategy holds great promise to revolutionize the use of engineered blood for future clinical applications., Competing Interests: Competing interests statement:The authors declare no competing interest.

- Abstract
Objectives: to investigate the influence of the leukoreduction moment (preor post-storage) of blood components on the clinical outcomes of patients transfused in the emergency department., Methods: retrospective cohort study of patients aged 18 years or older who received preor post-storage leukoreduced red blood cell or platelet concentrate in the emergency department and remained in the institution for more than 24 hours. A generalized mixed-effects model was applied in the analyses., Results: in a sample of 373 patients (63.27% male, mean age 54.83) and 643 transfusions (69.98% red blood cell), it was identified that the leukoreduction moment influenced the length of hospital stay (p<0.009), but was not dependent on the transfused blood component (p=0.124). The leukoreduction moment had no effect (p>0.050) on transfusion reactions, healthcare-associated infections, or mortality., Conclusions: patients who received pre-storage leukoreduced blood components in the emergency department had a shorter length of hospital stay.

- Abstract
An investigation was conducted to examine the impact of restrictive blood transfusion on the safety of early rebleeding following endoscopic variceal ligation (EVL) in patients with liver cirrhosis. Data were collected from patients with cirrhosis and esophageal varices who underwent EVL at the Affiliated Hospital of North Sichuan Medical College between September 2021 and March 2023. Clinical information, including serum albumin levels, hemoglobin (Hb) levels, liver function classification, and the occurrence of early rebleeding, was recorded. Patients were divided into 2 groups based on their Hb levels: 60 g/L to 90 g/L (restrictive blood transfusion) or Hb ≥ 90 g/L after EVL. The impact of restrictive transfusion on the post-ligation safety of EVL was observed. A total of 246 cirrhotic patients were included in the analysis. Significant differences were found in Hb levels, liver function classification, early rebleeding rates, length of hospital stay, and hospitalization expenses between the restrictive transfusion and Hb ≥ 90 g/L groups. The early rebleeding rate was significantly varied between the groups with different Hb levels after EVL. Multivariate logistic analysis revealed that restrictive blood transfusion (OR = 4.61, 95% CI: 1.06-19.99; P = .041), Hb (OR = 0.96, 95% CI: 0.95-0.97; P < .001), and Child-Pugh class C (OR = 6.37, 95% CI: 1.28-31.67; P = .024) were identified as independent factors influencing early rebleeding. Our findings suggest that the risk of early rebleeding in cirrhotic patients after EVL may be increased by restrictive blood transfusion, and this should be further investigated in future research., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

- Abstract
Objectives: The study aimed to establish a nomogram predictive model for blood transfusion after artificial femoral head replacement surgery in elderly patients with intertrochanteric fractures., Patients and Methods: Two hundred five elderly patients (55 males, 150 females; mean age: 82.1±6.6 years; range, 63 to 103 years) with intertrochanteric femoral fractures who underwent artificial femoral head replacement surgery between January 2015 and May 2023 were retrospectively analyzed. The patients were randomly divided into two groups: the training group (n=143) and the validation group (n=62). Within the training group, patients were further categorized into the nontransfused (n=86) and transfused (n=57) groups. Perioperative data were collected for logistic regression analysis to identify risk factors for postoperative blood transfusion. A nomogram model was developed to predict the need for blood transfusion, with assessments including the C-index, receiver operating characteristic curve, decision curve analysis, and clinical impact curve., Results: Logistic regression analysis showed that low preoperative hemoglobin levels, high intraoperative bleeding volume, high drainage volume, the use of wire reinforcement, and history of cerebral infarction were the independent risk factors for transfusion after femoral head replacement. Both decision curve analysis and clinical impact curves indicated that the prediction model could be used as a good prediction tool for blood transfusion after artificial femoral head replacement for intertrochanteric femoral fractures in the elderly., Conclusion: A nomogram prediction model that effectively assesses the risk of blood transfusion in elderly patients undergoing femoral head replacement for intertrochanteric femoral fractures was established in this study. This model demonstrated high predictive accuracy and consistency, providing a valuable tool for clinicians to identify high-risk patients and implement early interventions to reduce the need for postoperative blood transfusions.

- Abstract
Acute transfusion reaction is mainly related to the infusion of blood or blood products resulting at any time within a day of the intervention. It ranges from a non-specific febrile episode to a life-threatening intravascular hemolysis. The severity of the reaction and the degree of morbidity are usually related to the degree of ABO incompatibility and the volume of blood transfused. Therefore, this study aimed to determine the incidence of acute transfusion reactions and its associated factors in Jimma University Medical Center, southwest Ethiopia. Institution-based cross-sectional study was conducted from 1 October to December 30, 2020. A total of 384 transfused patients were followed in this study. Socio-demographic and clinical data were collected through a structured questionnaire. Baseline measurement and 24-hour periodic vital signs monitoring were conducted after each transfusion. Four milliliters of venous blood were drawn after transfusion intervention from each distrusted patient for complete blood count, blood group phenotype, direct antihuman globulin test (DAT), and crossmatching. Data were entered into Epi data version 3.1 and analyzed using Statistical Package for Social Science software (SPSS) version 20. Descriptive statistics, and bivariable and multivariable logistic regression were employed to test the association between independent and dependent variables. A P value ≤ .05 was considered to indicate statistical significance. Acute transfusion reactions were diagnosed in 5.7% of patients, with most of these reactions were febrile nonhemolytic reactions (63.6%) followed by allergic (36.4%) reactions with mild clinical manifestations (27.3%). Transfusion history, transfused blood that was kept for more than 13 days, abortion history, and number of transfused units (≥3 units of blood/blood component) have 3.3, 3.85, 4.2, and 3.9 times greater odds, respectively, besides their significant association with the incidence of acute transfusion reactions. Patients with a history of previous transfusion, abortion, multi-unit transfusion, and patients transfused with blood stored for ≥14 days should be closely monitored. Starting a hemovigilance system of monitoring, collecting, and evaluating data on adverse effects of blood transfusion locally and nationally will decrease the occurrence of acute transfusion reactions., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

- Abstract
This article highlights a case of high-dose ferric carboxymaltose (Ferinject
® ) for the treatment of perioperative iron deficiency anaemia in a 39-year-old patient with dysplastic coxarthrosis. The patient was admitted routinely for a total hip replacement of the left hip joint. She had been suffering from pain, lameness, and restriction of movement in her left hip joint for the past several years. The patient was admitted with initial iron deficiency anaemia of a medium severity (Hgb-96.5 g/L, RBC-3.97 × 1012 /L). Laboratory tests were taken to determine the iron deficiency, and transfusion readiness was submitted. The patient received ferric carboxymaltose infusion before surgery. The intraoperative blood loss was-100 mL with an operation duration of 50 min. On the first postoperative day, haemoglobin decreased to 86 g/L. No haemoglobin decrease was observed in the postoperative period, and 92 g/L was the amount of haemoglobin at the time of hospital discharge. The optimal dose for the treatment of perioperative anaemia has not been established; some studies recommend ferric carboxymaltose at a dose of 15 to 20 mg/kg and a maximum of 1000 mg once on the first day after surgery. The uniqueness of this case report is that a high dose of ferric carboxymaltose (1340 mg) during the preoperative period was applied. No side effects such as hypophosphatemia were reported. We believe that, in this clinical case, the patient managed to avoid large intraoperative blood loss and transfusions by using high doses of ferric carboxymaltose.- Published

- Abstract
Background: Mortality reviews examine US military fatalities resulting from traumatic injuries during combat operations. These reviews are essential to the evolution of the military trauma system to improve individual, unit, and system-level trauma care delivery and inform trauma system protocols and guidelines. This study identifies specific prehospital and hospital interventions with the potential to provide survival benefits., Methods: US Special Operations Command fatalities with battle injuries deemed potentially survivable (2001-2021) were extracted from previous mortality reviews. A military trauma review panel consisting of trauma surgeons, forensic pathologists, and prehospital and emergency medicine specialists conducted a methodical review to identify prehospital, hospital, and resuscitation interventions (e.g., laparotomy, blood transfusion) with the potential to have provided a survival benefit., Results: Of 388 US Special Operations Command battle-injured fatalities, 100 were deemed potentially survivable. Of these (median age, 29 years; all male), 76.0% were injured in Afghanistan, and 75% died prehospital. Gunshot wounds were in 62.0%, followed by blast injury (37%), and blunt force injury (1.0%). Most had a Maximum Abbreviated Injury Scale severity classified as 4 (severe) (55.0%) and 5 (critical) (41.0%). The panel recommended 433 interventions (prehospital, 188; hospital, 315). The most recommended prehospital intervention was blood transfusion (95%), followed by finger/tube thoracostomy (47%). The most common hospital recommendations were thoracotomy and definitive vascular repair. Whole blood transfusion was assessed for each fatality: 74% would have required ≥10 U of blood, 20% would have required 5 to 10 U, 1% would have required 1 to 4 U, and 5% would not have required blood products to impact survival. Five may have benefited from a prehospital laparotomy., Conclusion: This study systematically identified capabilities needed to provide a survival benefit and examined interventions needed to inform trauma system efforts along the continuum of care. The determination was that blood transfusion and massive transfusion shortly after traumatic injury would impact survival the most., Level of Evidence: Prognostic and Epidemiological; Level V., (Copyright © 2024 Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a “work of the United States Government” for which copyright protection under Title 17 of the United States Code is not available.

Abstract: Battlefield lessons learned are forgotten; the current name for this is the Walker Dip. Blood transfusion and the need for a Department of Defense Blood Program are lessons that have cycled through being learned during wartime, forgotten, and then relearned during the next war. The military will always need a blood program to support combat and contingency operations. Also, blood supply to the battlefield has planning factors that have been consistent over a century. In 2024, it is imperative that we codify these lessons learned. The linchpins of modern combat casualty care are optimal prehospital care, early whole blood transfusion, and forward surgical care. This current opinion comprised of authors from all three military Services, the Joint Trauma System, the Armed Services Blood Program, blood SMEs and the CCC Research Program discuss two vital necessities for a successful military trauma system: (1) the need for an Armed Services Blood Program and (2) Planning factors for current and future deployed military ere is no effective care for wounded soldiers, and by extension there is no effective military medicine., (Copyright © 2024 Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a “work of the United States Government” for which copyright protection under Title 17 of the United States Code is not available.

- Abstract
Blood transfusion is a critical life-saving medical intervention, but it carries the risk of transfusion-transmitted infections (TTIs) that can lead to serious consequences. TTIs include viral, bacterial, parasitic, and prion infections, transmitted through asymptomatic donor blood, contamination of stored blood products, or transfusion-related immunosuppression. Recognized global agents posing challenges to blood safety include human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV), Syphilis, etc. Emerging pathogens like SARS-CoV-2, hepatitis E, and others present additional risks. The residual risk of TTIs, representing the likelihood of infected donations passing screening tests, varies globally. High-income countries generally show lower prevalence rates than low-income countries. In Egypt, the estimated prevalence rates for HIV, HBV, HCV, and syphilis markers among the donors are 0.23 %, 0.76 %, 2.33 %, and 0.24 %, respectively. In Egypt, specific residual risk estimates are scarce, but prevalence rates for key infections highlight existing challenges. The World Health Organization promotes a global blood safety strategy, advocating for national blood systems, voluntary non-remunerated donors, and quality-assured testing. Despite these measures, the establishment of a haemovigilance system which is critical for monitoring and preventing adverse events, including TTIs, is reported as lacking in Egypt. This highlights the importance of comprehensive surveillance and safety measures in the blood donation process to ensure universal access to safe blood. Primary health care can play a pivotal role in preventing TTIs., Competing Interests: Declaration of Competing Interest The authors declare that they have no competing interests., (Copyright © 2024 Elsevier Ltd.

- Abstract
Background and Objectives: E-learning programmes are increasingly offered in transfusion medicine (TM) education. The aim of this study was to explore facilitators and barriers to TM e-learning programmes, including assessment of learning outcomes and measures of effectiveness., Materials and Methods: Participants selected from a prior survey and representing a diverse number of international e-learning programmes were invited to participate. A mixed methodology was employed, combining a survey and individual semi-structured one-on-one interviews. Interview data were analysed inductively to explore programme development, evaluation, and facilitators and barriers to implementation., Results: Fourteen participants representing 13 institutions participated in the survey and 10 were interviewed. The e-learning programmes have been in use for a variable duration between 5 and 16 years. Funding sources varied, including government and institutional support. Learner assessment methods varied and encompassed multiple-choice-questions (n = 12), direct observation (n = 4) and competency assessment (n = 4). Most regional and national blood collection agencies rely on user feedback and short-term learning assessments to evaluate their programmes. Only one respondent indicated an attempt to correlate e-learning with clinical practices. Factors that facilitated programme implementation included support from management and external audits to ensure compliance with regulatory educational and training requirements. Barriers to programme implementation included the allocation of staff time for in-house development, enforcing compliance, keeping educational content up-to-date and gaining access to outcome data for educational providers., Conclusion: There is evidence of considerable diversity in the evaluation of e-learning programmes. Further work is needed to understand the ultimate impact of TM e-learning on transfusion practices and patient outcomes., (© 2024 International Society of Blood Transfusion.)

- Abstract
Background and Objectives: Blood safety measures used by blood establishments to increase blood component safety can be validated using Transfusion-Relevant Bacterial Reference Strains (TRBRS). Ultra-cold storage conditions and manual preparation of the current TRBRS may restrict their practical use. To address this issue, the ISBT Transfusion-Transmitted Infectious Diseases Working Party's Bacterial Subgroup organized an international study to validate TRBRS in a user-friendly, lyophilised format., Materials and Methods: Two bacterial strains Klebsiella pneumoniae PEI-B-P-08 and Staphylococcus aureus PEI-B-P-63 were manufactured as lyophilised material. The lyophilised bacteria were distributed to 11 different labs worldwide to assess the robustness for enumeration, identification and determination of growth kinetics in platelet concentrates (PCs)., Results: Production of lyophilised TRBRS had no impact on the growth properties compared with the traditional format. The new format allows a direct low-quantity spiking of approximately 30 bacteria in PCs for transfusion-relevant experiments. In addition, the lyophilised bacteria exhibit long-term stability across a broad temperature range and can even be directly rehydrated in PCs without losing viability. Interlaboratory comparative study demonstrated the robustness of the new format as 100% of spiked PC exhibited growth., Conclusion: Lyophilised TRBRS provide a user-friendly material for transfusion-related studies. TRBRS in the new format have improved features that may lead to a more frequent use in the quality control of transfusion-related safety measures in the future., (© 2024 The Authors.

- Abstract
Prior studies reveal adverse effects of transfusion on cardiac surgery, but little is known of transfusion impact on heart transplantation. First-time, single-organ adult heart transplant recipients between January 1, 2010, and December 31, 2020, were included, stratified above or below a model for end-stage liver disease excluding international normalized ratio (MELD-XI) score of 9.4, and propensity score matched to their nearest neighbor. A 90 day landmark analysis within each cohort was also performed. Unadjusted analysis showed transfusion recipients, MELD-XI ≥9.4, were more likely to experience post-heart transplantation mortality (Hazard Ratio (HR), 1.352 [95% Confidence Interval (CI), 1.239-1.477], p < 0.001), persisting after adjustment for potential confounders (adjusted HR, 1.211 [95% CI, 1.100-1.335], p < 0.001) and after propensity-score matching (HR, 1.174 [95% CI, 1.045-1.319], p = 0.007). Post-transplant length of stay was longer (25.9 vs. 23.2 days, p < 0.001). Post-transplant dialysis was more common (18.7 vs. 15.9%, p = 0.009). There was no survival difference on 90 day landmarked analysis ( p = 0.108). With MELD-XI <9.4, there was slight survival detriment among transfusion recipients on univariable analysis (HR, 1.111 [95% CI, 1.001-1.234], p = 0.049) but not on multivariable analysis (adjusted HR, 1.061 [95% CI, 0.952-1.181], p = 0.285). There was similar survival after propensity-score matching (HR, 1.032 [95% CI, 0.903-1.180], p = 0.642) and on landmark analysis ( p = 0.581). Ultimately, transfusion was associated with worse post-heart transplantation outcomes among recipients with a MELD-XI ≥9.4., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © ASAIO 2024.)

Abstract: This review describes the necessity, evolution, and current state of prehospital blood programs in the United States. Less than 1% of 9-1-1 ground emergency medical service agencies have been able to successfully implement prehospital blood transfusions as part of a resuscitation strategy for patients in hemorrhagic shock despite estimates that annually between 54,000 and 900,000 patients may benefit from its use. The use of prehospital blood transfusions as a tool for managing hemorrhagic shock has barriers to overcome to ensure it becomes widely available to patients throughout the United States. Barriers include (1) current state Emergency Medical Services clinicians' scope of practice limitations; (2) program costs and reimbursement of blood products; (3) no centralized data collection process for prehospital hemorrhagic shock and patient outcomes; (4) collaboration between prehospital agencies, blood suppliers, and hospital clinicians and transfusion service activities. The following article identifies barriers and a proposed roadmap to reduce death due to prehospital hemorrhage., (Copyright © 2024 The Author(s).

- Abstract
Blood transfusions save lives and improve health every day. Despite the matching of blood types being stricter than it ever has been, emergency transfusions among incompatible blood types are still inevitable in the clinic when there is a lack of acceptable blood types for recipients. Here to overcome this, a counter measure nanoplatform consisting of a polymeric core coated by a red blood cell (RBC) membrane is developed. With A-type or B-type RBC membrane camouflaging, the nanoplatform is capable of specifically capturing anti-A or anti-B IgM antibodies within B-type or A-type whole blood, thereby decreasing the corresponding IgM antibody levels and then allowing the incompatible blood transfusions. In addition to IgM, the anti-RBC IgG antibody in a passive immunization murine model can likewise be neutralized by this nanoplatform, leading to prolonged circulation time of incompatible donor RBCs. Noteworthily, nanoplatform made by expired RBCs (>42 days stored hypothermically) and then subjected to lyophilization does not impair their effect on antibody neutralization. Most importantly, antibody-captured RBC-NP do not exacerbate the risk of inflammation, complement activation, and coagulopathy in an acute hemorrhagic shock murine model. Overall, this biomimetic nanoplatform can safely neutralize the antibody to enable incompatible blood transfusion., (© 2024 The Author(s). Advanced Science published by Wiley‐VCH GmbH.)

- Abstract
Background: Viscoelastometric haemostatic assays (VHA) give rapid information on coagulation status, allowing individualised resuscitation., Methods: This paper compares outcomes from two observational studies of postpartum haemorrhage (PPH) in the same institution, before and after practice changed from fixed ratio empirical transfusion of coagulation products with laboratory coagulation testing to VHA-guided fibrinogen replacement incorporated into an enhanced PPH care bundle. In both studies, all blood samples were taken near 1000 mL qualitative blood loss (QBL). In Study One, QBL started once PPH was identified, and resuscitation with coagulation blood products was empirical or based on laboratory tests of coagulation. In Study Two, QBL started at delivery and VHA was used to guide fibrinogen replacement if FIBTEM A5 was <12 mm (Claus fibrinogen ≤2 g/L) or to withhold coagulation products if FIBTEM A5 was >12 mm., Results: Improved PPH outcomes were observed in Study Two, with rates of measured blood loss ≥2500 mL, ≥4 units red blood cell (RBC) transfusion, fresh frozen plasma transfusion and ≥8 units of any blood product transfusion all reduced (P < 0.01). Clinically significant improvements occurred in women with fibrinogen ≤2 g/L at study entry, where the proportion of women who received ≥4 units RBC transfusion fell from 67% in Study One to 0% in Study Two (P = 0.0007)., Conclusions: These results suggest that use of VHA as part of an early bundle of PPH care targeting fibrinogen ≤2 g/L with fibrinogen concentrate reduces PPH progression. The greatest benefit was seen when fibrinogen levels were ≤2 g/L at first testing., (Crown Copyright © 2024. Published by Elsevier Ltd. All rights reserved.)

- Abstract
Early resuscitation using blood products is critical for patients with severe hemorrhagic shock. We aimed to develop and validate a new scoring system, hemorrhagic shock transfusion prediction (HSTP) score, to predict the need for massive transfusion (MT) in these patients, compared to the widely used Assessment of Blood Consumption (ABC) score. Trauma patients admitted to Emtiaz Hospital in Iran from 2017 to 2021 were retrospectively included. Patients assigned a code 1 or 2 according to the Emergency severity index (ESI) triage system have been divided into MT and non-MT groups. MT was defined as receiving ≥ 10 units of packed cells (PCs) in 24 h. Demographic information, admission vital signs, and lab results available within 15 min were compared between the groups. A new predictive score was developed using logistic regression of statistically significant parameters. Out of 1029 patients, 651 (63.3%) required MT. An arrival, diastolic blood pressure < 79.5 mm Hg, absolute lymphocyte count > 1850/μL, base excess < - 4.25, and blood glucose > 156 mg/dL were independent predictors included in the HSTP score. The sensitivity and specificity were 74.36% and 53.87% for the HSTP score, compared to 31.03% and 76.16% for the ABC score. Moreover, the positive and negative predictive values were 77.88% and 49.03% for the HSTP score, versus 74.15% and 33.66% for ABC. The new scoring system demonstrated higher sensitivity and improved positive and negative predictive values compared to the ABC score. This score can assist physicians in making accurate transfusion decisions quickly, but further prospective studies are warranted to validate its clinical utility., (© 2024.

- Abstract
Background: Transfusion-dependent thalassemia (TDT) is a severe form of beta-thalassemia, characterized by defective-globin production, resulting in a buildup of unpaired alpha globin chains. Patients with TDT can only survive if they receive safe blood transfusions regularly, which causes iron overload in their blood, which causes a variety of disorders. Cations and trace elements in TDT patients as a drug target deserve more studies., Objectives: In the present study, the cations and some trace elements were studied in TDT patients as a tool to adjust their level in the case of any disturbances., Methods: Serum calcium, magnesium, zinc, copper, and iron were measured spectrophotometrically while manganese and cobalt were measured by flameless atomic absorption spectroscopy in 100 TDT patients and compared with 35 healthy control children., Results: Patients with TDT exhibit a notable elevation in blood levels of iron, copper, copper/zinc ratio, and manganese, with a substantial reduction in serum levels of zinc, magnesium, calcium, and cobalt, as compared to the control group. These minerals have diverse associations with clinical data and transfusion frequencies. The receiver operating characteristic (ROC) analysis revealed that the elevated levels of iron, manganese, and calcium exhibit the greatest diagnostic capability, with a sensitivity and specificity of over 80 %, and a Youdin's J value of more than 0.6., Conclusion: The levels of cations and trace elements are disturbed in TDT patients. Hence, the monitoring and adjustment of the level of these minerals are important to prevent further consequences., Competing Interests: Conflict of interest The authors declare no conflicts of interest with any commercial or other affiliation on the submitted paper., (Copyright © 2024 Elsevier Ltd.

- Abstract
Blood transfusion is a common therapeutic intervention in hospitalized patients. There are numerous indications for transfusion, including anemia and coagulopathy with deficiency of single or multiple coagulation components such as platelets or coagulation factors. Nevertheless, the practice of transfusion in critically ill patients has been controversial mainly due to a lack of evidence and the need to consider the appropriate clinical context for transfusion. Further, transfusion carries many risk factors that must be balanced with benefits. Therefore, transfusion practice in ICU patients has constantly evolved, and we endeavor to present a contemporary review of transfusion practices in this population guided by clinical trials and expert guidelines.

- Abstract
Background and Objectives: Total knee arthroplasty (TKA) is sometimes associated with significant perioperative bleeding. The aim of this study was to determine the efficacy of tranexamic acid (TXA) in reducing perioperative blood loss in patients undergoing primary TKA. The secondary objectives were to assess the efficacy of TXA in reducing the need for blood transfusion in these patients and to determine its effect on verticalization and ambulation after TKA. Materials and Methods: This study included 96 patients who were randomly assigned to two groups, each containing 48 patients. The study group received intravenous TXA at two time points: immediately after the induction with doses of 15 mg/kg and 10 mg/kg 15 min before the release of the pneumatic tourniquet. The control group received an equivalent volume of 0.9% saline solution via the same route. Results: TXA markedly reduced (Z = -6.512, p < 0.001) the total perioperative blood loss from 892.56 ± 324.46 mL, median 800 mL, interquartile range (IQR) 530 mL in the control group, to 411.96 ± 172.74 mL, median 375 mL, IQR 200 mL, in the TXA group. In the TXA group, only 5 (10.4%) patients received a transfusion, while in the control group, 22 (45.83%) received it (χ2 = 15.536, p = 0.001). Patients in the study group stood (χ2 = 21.162, p < 0.001) and ambulated earlier postoperatively, compared to the control group (χ2 = 26.274, p < 0.001). Patients who received TXA had a better overall postoperative functional recovery. There was a statistically significant difference in all the above results. Conclusions: TXA is an effective drug for reducing the incidence of perioperative bleeding, decreasing transfusion rates, and indirectly improving postoperative functional recovery in patients undergoing primary TKA.

- Abstract
Background: Although whole blood (WB) transfusion was reported to improve survival in trauma patients with hemorrhagic shock, little is known whether a higher proportion of WB is associated with an improved survival. This study aimed to evaluate the association between whole blood ratio (WBR) and the risk of mortality in trauma patients requiring massive blood transfusion., Methods: We performed a retrospective cohort study from the ACS-TQIP between 2020 and 2021. Patients were aged ≥ 18 years and received WB within 4 h of hospital arrival as a part of massive blood transfusion. Study patients were categorized into four groups based on the quartiles of WBR. Primary outcome was 24-h mortality and secondary outcome was 30-day mortality. Multivariable logistic regression analysis, fitted with generalized estimating equations, was performed to adjust for confounding factors and accounted for within-hospital clustering., Results: A total of 4087 patients were eligible for analysis. The median age was 37 years (interquartile range [IQR]: 27-53 years), and 85.0% of patients were male. The median number of WB transfusions was 2.3 units (IQR 2.0-4.0 units), and the total transfusion volume was 4940 ml (IQR 3350-8504). When compared to the lowest WBR quartile, the highest WBR quartile had lower adjusted 24-h mortality (adjusted odds ratio [AOR]: 0.61, 95% confidence interval [CI]: 0.46-0.81) and 30-day mortality (AOR 0.58; 95% CI 0.45-0.75)., Conclusion: The probability of mortality consistently decreased with higher WBR in trauma patients requiring massive blood transfusion., (© 2024.

- Abstract
Emergency general surgeons often provide care to severely ill patients requiring surgical interventions and intensive support. One of the primary drivers of morbidity and mortality is perioperative bleeding. In general, when addressing life threatening haemorrhage, blood transfusion can become an essential part of overall resuscitation. However, under all circumstances, indications for blood transfusion must be accurately evaluated. When patients decline blood transfusions, regardless of the reason, surgeons should aim to provide optimal care and respect and accommodate each patient's values and target the best outcome possible given the patient's desires and his/her clinical condition. The aim of this position paper was to perform a review of the existing literature and to provide comprehensive recommendations on organizational, surgical, anaesthetic, and haemostatic strategies that can be used to provide optimal peri-operative blood management, reduce, or avoid blood transfusions and ultimately improve patient outcomes., (© 2024.

- Abstract
Periodic blood transfusion is a need in cancer patients in which the disease process as well as the chemotherapy can disrupt the natural production of blood cells. However, there are concerns about blood transfusion side effects, the cost, and the availability of donated blood. Therefore, predicting the timely requirement for blood transfusion considering patient variability is a need, and here for the first-time deal with this issue in blood cancer using in vivo data. First, a data set of 98 samples of blood cancer patients including 61 features of demographic, clinical, and laboratory data are collected. After performing multivariate analysis and the approval of an expert, effective parameters are derived. Then using a deep recurrent neural network, a system is presented to predict a need for packed red blood cell transfusion. Here, we use a Long Short-Term Memory (LSTM) neural network for modeling and the cross-validation technique with 5 layers for validation of the model along with comparing the result with networking and non-networking machine learning algorithms including bidirectional LSTM, AdaBoost, bagging decision tree based, bagging KNeighbors, and Multi-Layer Perceptron (MLP). Results show the LSTM outperforms the other methods. Then, using the swarm of fuzzy bioinspired nanomachines and the most effective parameters of Hgb, PaO
2 , and pH, we propose a feasibility study on nano fuzzy alarming system (NFABT) for blood transfusion requirements. Alarming decisions using the Internet of Things (IoT) gateway are delivered to the physician for performing medical actions. Also, NFABT is considered a real-time non-invasive AI-based hemoglobin monitoring and alarming method. Results show the merits of the proposed method., (© 2024. The Author(s).)- Published

- Abstract
Introduction: Traumatically injured combat casualties urgently need both blood and surgery. Forward Surgical Teams (FSTs) or Role 2 (R2) surgical teams were created to minimize the time-space distance from point of injury to damage control surgery. Our goal is to describe the use of blood products from a Split FST deployed to Green Village from July 2018 to April 2019., Materials and Methods: A retrospective review of a collection of patients treated by a single R2 was conducted following institutional regulatory approval. De-identified data were input into the study database and were then retrospectively reviewed for patients who presented to and received treatment at the R2 facility., Results: Of the 470 total patients treated in 10 months: 226 (48%) received blood products and 132 (28%) underwent operative procedures. The patients were 98% male; 74% Host Nationals (HN), 24% North American Treaty Organization members. Mechanism of injury was 75% explosive and 98% penetrating. Documented Injury Severity Scores (n = 214) were: <9 (n = 57/27%), 9 to 15 (n = 34/16%), 16 to 25 (n = 64/30%), and >25 (n = 59/28%). In total 1,052 units of blood products were administered: whole blood (n = 495), red blood cells (n = 200), fresh frozen plasma (n = 109), and liquid plasma (n = 248). HN whole blood used was 337/495 (68%) units for 78 patients; walking blood bank was mobilized six times for HN patients. Of the patients seen, >99% who arrived with a pulse survived to be discharged to a higher level of care., Conclusions: This analysis describes blood usage associated with one high volume forward deployed operative team and demonstrates the vital importance of the R2 split FST to provide coalition forces with surgical care in proximity to the point of injury. Over time, the supply chain has improved with more component therapy available at R2s; however, the need for walking blood bank and innovative solutions to care for all casualties must be part of small team capabilities. Liquid plasma use should be expanded as soon as it is feasible., (© The Association of Military Surgeons of the United States 2023. All rights reserved.

- Abstract
Surgical patients are often transfused to manage bleeding and anemia. Best practices for red blood cell (RBC) transfusion administration in patient having noncardiac surgery remains controversial and a robust evaluation and description of perioperative transfusion practices is lacking. We characterized perioperative hemoglobin concentrations and transfusion practices from the prospective VISION cohort which included 39,222 patients aged ≥45 years who had inpatient noncardiac surgery. Variations in transfusion practices were analyzed using hierarchical mixed models, and associations with mortality and complications were evaluated using a nested frailty survival model. Within the cohort, 16.1% (n = 6296) were given perioperative RBC transfusions, with the fraction declining from 20% to 13% over the 6-year study period. The proportion of patients transfused varied by surgery type from 6.4% for low-risk operations (i.e., minor surgery) to 31.5% for orthopedic surgeries. Variations were largely associated with patient hemoglobin concentrations, but also with center (range: 3.7%-27.3%) and country (0.4%-25.3%). Even after adjusting for baseline hemoglobin, comorbidities and type of surgery, both center and country were significant sources of variation in transfusion practices. Among transfused participants, 60.4% (n = 3728/6170) had at least 1 hemoglobin concentration ≤80g/L and 86.0% (n = 5305/6170) had at least 1 hemoglobin concentration ≤90g/L, suggesting that relatively restrictive transfusion strategies were used in most. The proportion of patients receiving at least 1 RBC transfusion declined from 20% to 13% over 6 years. However, there was considerable unexplained variation in transfusion practices., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

- Abstract
Objectives: To derive systematic-review informed, modified Delphi consensus regarding prophylactic transfusions in neonates and children supported with extracorporeal membrane oxygenation (ECMO) from the Pediatric ECMO Anticoagulation CollaborativE., Data Sources: A structured literature search was performed using PubMed, EMBASE, and Cochrane Library (CENTRAL) databases from January 1988 to May 2020, with an update in May 2021., Study Selection: Included studies assessed use of prophylactic blood product transfusion in pediatric ECMO., Data Extraction: Two authors reviewed all citations independently, with a third independent reviewer resolving conflicts. Thirty-three references were used for data extraction and informed recommendations. Evidence tables were constructed using a standardized data extraction form., Measurements and Main Results: The evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation system. Forty-eight experts met over 2 years to develop evidence-informed recommendations and, when evidence was lacking, expert-based consensus statements or good practice statements for prophylactic transfusion strategies for children supported with ECMO. A web-based modified Delphi process was used to build consensus via the Research And Development/University of California Appropriateness Method. Consensus was based on a modified Delphi process with agreement defined as greater than 80%. We developed two good practice statements, 4 weak recommendations, and three expert consensus statements., Conclusions: Despite the frequency with which pediatric ECMO patients are transfused, there is insufficient evidence to formulate evidence-based prophylactic transfusion strategies., Competing Interests: The Executive Committee (Drs. Alexander, Muszynski, Bembea, Cheifetz, Steiner, and Barbaro) served as arbitrators for conflict of interest management. Dr. Alexander’s institution received funding from Novartis (consultant on the end-point adjudication committee for Prospective Trial to Assess the Angiotensin Receptor Blocker Neprilysin Inhibitor LCZ696 Versus Angiotensin-Converting Enzyme Inhibitor for the Medical Treatment of Pediatric HF [PANORAMA-HF] clinical trial). Dr. Sloan commenced employment with CSL Behring after the consensus process was complete. Dr. Kneyber received funding from Metran. Drs. Alexander and Muszynski’s institutions received funding from the National Institutes of Health (NIH); they received support for article research from the NIH.

- Abstract
Abstract: Peri-operative management of cyanotic congenital heart disease in a patient of sickle cell disease (SCD) can be challenging. We report a case of Tetralogy of Fallot and homozygous SCD with history of multiple blood transfusions and sickle cell crises who underwent intracardiac repair. Hemoglobin S level was reduced from 75% pre-operative to 21.8% postoperative with a combination of pre-operative blood transfusion, intraoperative exchange transfusion, and normothermic cardiopulmonary bypass (CPB). Pre-operative optimization and safe intraoperative conduct were essential to avoid sickling crises., (Copyright © 2024 Copyright: © 2024 Annals of Cardiac Anaesthesia.)

- Abstract
Objectives: To develop a pre-operative tool to estimate the risk of peri-operative packed red blood cell transfusion in primary debulking surgery., Methods: We retrospectively reviewed an institutional database to identify patients who underwent primary debulking surgery for ovarian cancer at a single center between January 1, 2001 and May 31, 2019. Receiver operating characteristic curve and area under the receiver operating characteristic curve (AUC) were calculated. Five-fold cross-validation was applied to the multivariate model. Significant variables were assigned a 'BLOODS' (BLood transfusion Over an Ovarian cancer Debulking Surgery) score of +1 if present. A total BLOODS score was calculated for each patient, and the odds of receiving a transfusion was determined for each score., Results: Overall, 1566 patients met eligibility criteria; 800 (51%) underwent a peri-operative blood transfusion. Odds ratios (OR) were statistically significant for American Society of Anesthesiologists scores of 3 and 4 (OR 1.34, 95% confidence interval (95% CI) 1.09 to 1.63), pre-operative levels of cancer antigen 125 (CA125) (OR 2.43, 95% CI 1.98 to 2.99), platelets (OR 1.59, 95% CI 1.45 to 1.74), obesity (OR 0.76, 95% CI 0.60 to 0.96), presence of carcinomatosis (OR 2.45, 95% CI 1.93 to 3.11), bulky upper abdominal disease (OR 2.86, 95% CI 2.32 to 3.54), pre-operative serum albumin level (OR 0.31, 95% CI 0.24 to 0.40), and pre-operative hemoglobin level (OR 0.56, 95% CI 0.51 to 0.61). The corrected AUC was 0.748 (95% CI 0.693 to 0.804). BLOODS scores of 0 and 5 corresponded to 11% and 73% odds, respectively, of receiving a peri-operative blood transfusion., Conclusions: We developed a universal pre-operative scoring system, the BLOODS score, to help identify patients with ovarian cancer who would benefit from surgical planning and blood-saving techniques. The BLOODS score was directly proportional to the American Society of Anesthesiologists score, presence of upper abdominal disease, carcinomatosis, CA125 level, and platelets level. We believe this model can help physicians with surgical planning and can benefit patient outcomes., Competing Interests: Competing interests: NR Abu-Rustum reports grant funding from GRAIL paid to the institution.

- Abstract
Purpose: This study investigates baseline patient demographics and predictors of vascular injury, blood transfusion, and compartment syndrome in patients with orthopaedic fractures secondary to GSWs at two high-volume Level I trauma centres., Methods: A retrospective chart review of all GSW-related trauma patients at two Level I trauma centres between July 2019 and September 2021 was conducted. Chi-squared and two-tailed independent t tests were used for data analysis, and logistic regression with odds ratios (OR) determined predictors of primary outcomes., Results: Among 478 GSW patients, 94 (19.7%) sustained 130 orthopaedic fractures, most commonly at the lower extremity (77.7%). Orthopaedic fracture patients showed significantly higher rates of vascular injury (29.8 vs. 4.7%, p < 0.001), transfusion (27.7 vs. 12.8%, p = 0.006), and compartment syndrome (3.2 vs. 0.3%, p = 0.011) compared to non-orthopaedic injury patients. Univariable analysis identified ankle (OR = 47.50, p < 0.001) and hip/femur fractures (OR = 5.31, p < 0.001) as predictors of vascular injury. Multivariable logistic regression revealed lower extremity vascular injury (OR = 54.69, p = 0.006) and anatomic fracture sites of the humerus (OR = 15.17, p = 0.008), clavicle/scapula (OR = 11.30, p = 0.009), and acetabulum/pelvis (OR = 7.17, p = 0.025) as predictors of blood transfusion. Univariable analysis showed lower extremity vascular injury (OR = 30.14, p = 0.007) as a predictor of compartment syndrome., Conclusion: These findings underscore the importance of diagnosing and managing vascular injuries and compartment syndrome in GSW-related orthopaedic fractures, emphasizing the necessity for targeted transfusion strategies in such cases., (© 2024.

- Abstract
Race and ethnicity are sociopolitical and not biological constructs, and assertions that these population descriptors have scientific meaning has caused significant harm. A critical assessment of the transfusion medicine literature is an important aspect of promoting race-conscious as opposed to race-based medicine. Utilizing current definitions and health equity frameworks, this review will provide a critical appraisal of transfusion medicine studies at the intersection of race and healthcare disparities, with a focus on larger methodological challenges facing the transfusion medicine community. Moving forward, risk modelling accounting for upstream factors, patient input, as well as an expert consensus on how to critically conduct and evaluate this type of literature are needed. Further, when using race and ethnicity in research contexts, investigators must be aware of existing guidelines for such reporting., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

- Abstract
Objectives: To assess if transfusion with low-titer group O whole blood (LTOWB) is associated with improved early and/or late survival compared with component blood product therapy (CT) in bleeding trauma patients., Data Sources: A systematic search of PubMed, CINAHL, and Web of Science was performed from their inception through December 1, 2023. Key terms included injury, hemorrhage, bleeding, blood transfusion, and whole blood., Study Selection: All studies comparing outcomes in injured civilian adults and children who received LTOWB versus CT were included., Data Extraction: Data including author, publication year, sample size, total blood volumes, and clinical outcomes were extracted from each article and reported following the Meta-analysis Of Observational Studies in Epidemiology guidelines. Main outcomes were 24-hour (early) and combined 28-day, 30-day, and in-hospital (late) mortality rates between recipients of LTOWB versus CT, which were pooled using random-effects models., Data Synthesis: Of 1297 studies reviewed, 24 were appropriate for analysis. Total subjects numbered 58,717 of whom 5,164 received LTOWB. Eleven studies included adults-only, seven included both adults and adolescents, and six only included children. The median (interquartile range) age for patients who received LTOWB and CT was 35 years (24-39) and 35.5 years (23-39), respectively. Overall, 14 studies reported early mortality and 22 studies reported late mortality. LTOWB was associated with improved 24-hour survival (risk ratios [RRs] [95% CI] = 1.07 [1.03-1.12]) and late (RR [95% CI] = 1.05 [1.01-1.09]) survival compared with component therapy. There was no evidence of small study bias and all studies were graded as a moderate level of bias., Conclusions: These data suggest hemostatic resuscitation with LTOWB compared with CT improves early and late survival outcomes in bleeding civilian trauma patients. The majority of subjects were injured adults; multicenter randomized controlled studies in injured adults and children are underway to confirm these findings., Competing Interests: Dr. Spinella is a consultant for Cerus and Hemanext, on the advisory board for Haima and Octapharma, and is a Co-Founder and Chief Medical Officer of Kalocyte. He also has funding from Biomedical Advanced Research and Development Authority to perform a trial examining the safety and efficacy of whole blood.
