Abstract
STUDY OBJECTIVE To evaluate the association between pretransfusion and posttransfusion hemoglobin concentrations and the outcomes of children undergoing noncardiac surgery. DESIGN Retrospective review of patient records. We focused on initial postoperative hemoglobin concentrations, which may provide a more useful representation of transfusion adequacy than pretransfusion hemoglobin triggers (the latter often cannot be obtained during acute surgical hemorrhage). SETTING Single-center, observational cohort study. PATIENTS We evaluated all pediatric patients undergoing noncardiac surgery who received intraoperative red blood cell transfusions from January 1, 2008, through December 31, 2018. INTERVENTIONS None. MEASUREMENTS Associations between pre- and posttransfusion hemoglobin concentrations (g/dL), hospital-free days, intensive care unit admission, postoperative mechanical ventilation, and infectious complications were evaluated with multivariable regression modeling. MAIN RESULTS In total, 113,713 unique noncardiac surgical procedures in pediatric patients were evaluated, and 741 procedures met inclusion criteria (median [range] age, 7 [1-14] years). Four hundred ninety-eight patients (68%) with a known preoperative hemoglobin level had anemia; of these, 14% had a preexisting diagnosis of anemia in their health record. Median (IQR) pretransfusion hemoglobin concentration was 8.1 (7.4-9.2) g/dL and median (IQR) initial postoperative hemoglobin concentration was 10.4 (9.3-11.6) g/dL. Each decrease of 1 g/dL in the initial postoperative hemoglobin concentration was associated with increased odds of transfusion within the first 24 postoperative hours (odds ratio [95% CI], 1.62 [1.37-1.93]; P < .001). No significant relationships were observed between postoperative hemoglobin concentrations and hospital-free days (P = .56), intensive care unit admission (P = .71), postoperative mechanical ventilation (P = .63), or infectious complications (P = .74). CONCLUSIONS In transfused patients, there was no association between postoperative hemoglobin values and clinical outcomes, except the need for subsequent transfusion. Most transfused patients presented to the operating room with anemia, which suggests a potential opportunity for perioperative optimization of health before surgery.

Abstract
PURPOSE OF REVIEW Postpartum anemia (PPA) is common in women after childbirth and affects about 50-80% of all women worldwide. Iron deficiency (ID) is the main cause for anemia and constitutes a potentially preventable condition with great impact on the mother's physical and mental condition after delivery. In most cases, PPA is associated with antenatal ID and peripartum blood losses. Numerous published studies confirmed the positive effect of PPA diagnosis and treatment. RECENT FINDINGS Iron deficiency as well as iron deficiency anemia (IDA) are common in the postpartum period and represent significant health problems in women of reproductive age. SUMMARY Important movements towards early detection and therapy of postpartum anemia have been observed. However, postpartum anemia management is not implemented on a large scale as many healthcare professionals are not aware of the most recent findings in the field. Diagnosis and therapy of PPA, particularly iron supplementation in ID and IDA, has proven to be highly effective with a tremendous effect on women's wellbeing and outcome.

Abstract
OBJECTIVE We aimed to describe hemoglobin (Hb) change after transfusion in the nonacute postpartum anemic population in order to provide clinicians with appropriate expectations regarding Hb rise posttransfusion. STUDY DESIGN We performed a secondary analysis of a randomized controlled trial comparing initial transfusion with 1 unit of packed red blood cells (pRBCs) to 2 units pRBCs for postpartum women requiring nonacute transfusion (n = 66). Inclusion criteria were: age 18 years and older, Hb level either <7 g/dL or >7 g/dL with signs or symptoms of anemia, and > 6 hours postpartum without contraindication to transfusion. Hb assessment was performed 4 to 6 hours after initial transfusion. Hb change (ΔHb) was calculated as posttransfusion Hb minus randomization Hb. Our primary goal was to describe mean ΔHb per pRBC transfused at the 4- to 6-hour posttransfusion blood count. We also compared ΔHb per pRBC transfused by number of units transfused, body mass index (BMI), and symptoms (dizziness and/or fatigue) at time of posttransfusion assessment. RESULTS Participants were mean age 29, mean BMI of 27, and over 70% self-identified as black, 12% identified as white, and 9% as Asian race. Mean Hb prior to transfusion was 6.9 ± 0.6 g/dL. Mean ΔHb per pRBC transfused was 0.9 ± 0.4g/dL. There was no difference in ΔHb per pRBC by BMI category (normal weight < 25 kg/m2: 1.1 ± 0.2 g/dL; overweight 25-29.9 kg/m2: 0.9 ± 0.5 g/dL; obese ≥ 30 kg/m2: 0.9 ± 0.5 g/dL; p = 0.12). Finally, there was also no significant difference in ΔHb per pRBC by whether or not symptoms of anemia persisted after initial transfusion (1.0 ± 0.7 vs. 0.9 ± 0.4 g/dL, p = 0.39). CONCLUSION Our data supports the classically accepted rise in Hb after pRBC of approximately 1 g/dL, regardless of BMI category or anemia symptomatology. The study population includes patients at highest risk of postpartum anemia. The results of our study provide important information for clinicians caring for postpartum patients with nonacute anemia. KEY POINTS · Postpartum anemia is a significant public health issue.. · Providers use hemoglobin change to assess response to blood transfusion.. · The established 1 g/dL change in Hb after transfusion is based on historic surgical populations.. · Our data suggests the 1 g/dL Hb change is applicable to postpartum patients..

Abstract
BACKGROUND Blood transfusion strategies in patients with acute myocardial infarction (AMI) and anemia are yet to be conclusively identified. Thus, we aim to assess the efficacy and safety of restrictive versus liberal blood transfusion strategies for AMI and anemia. METHODS A systematic review and meta-analysis of randomized controlled trials (RCTs) retrieved from PubMed, web of science, SCOPUS, EMBASE, and Cochrane Central Register of Controlled Trials were performed through November 2023. We used RevMan V. 5.4 to pool dichotomous data using risk ratio (RR) and continuous data using mean difference (MD) with a 95% confidence interval (CI). (PROSPERO): ID: CRD42023490692. RESULTS We included four RCTs with 4.325 patients. There was no significant difference between both groups regarding MACE whether at 30 days (RR: 0.93 with 95% CI [0.57-1.51], P = 0.76) or ≥ six months (RR: 1.17 with 95% CI [0.95-1.45], P = 0.14), all-cause mortality at 30 days (RR: 1.16 with 95% CI [0.95-1.40], P = 0.14) or ≥ six months (RR: 1.16 with 95% CI [0.88-1.53], P = 0.28). However, the liberal strategy was significantly associated with increased hemoglobin level change (MD: -1.44 with 95% CI [-1.68 to -1.20], P < 0.00001). However, the restrictive strategy was significantly associated with a lower incidence of acute lung injury (RR: 0.11 with 95% CI [0.02-0.60], P = 0.01). CONCLUSION There was no significant difference between the restrictive blood transfusion strategy and the liberal blood transfusion strategy regarding the clinical outcomes. However, restrictive blood transfusion strategy was significantly associated with a lower incidence of acute lung injury than liberal blood transfusion strategy.

Abstract
Anemia is a highly prevalent condition that may compromise oxygen delivery to vital organs, especially among the critically ill. Although current evidence supports the adoption of a restrictive transfusion strategy and threshold among the nonbleeding critically ill patient, it remains unclear whether this practice should apply to the brain-injured patient, given the predisposition to cerebral ischemia in this patient population, in which even nonprofound anemia may exert a detrimental effect on clinical outcomes. The purpose of this review is to provide an overview of the pathophysiological changes related to impaired cerebral oxygenation in the brain-injured patient and to present the available evidence on the effect of anemia and varying transfusion thresholds on the clinical outcomes of patients with acute brain injury.

Abstract
PURPOSE About 40% of pregnant women are anemic and at an increased risk for complications. We examined the efficacy of inpatient anemia workup and treatment in pregnant women diagnosed with moderate-severe anemia (hemoglobin < 10 mg/dL), during hospitalization in the late second-trimester and third-trimester. METHODS This retrospective study, conducted between March 2020 and November 2022, included women at ≥ 24 gestational weeks who were hospitalized due to various indications and diagnosed with anemia (hemoglobin < 10 mg/dL). The study group comprised women who underwent an inpatient anemia workup and initiation of anemia treatment. The comparison group comprised women who did not undergo an inpatient anemia investigation. The primary outcome was the rate of pre-delivery hemoglobin > 11 g/dL. RESULTS The most frequent etiology of anemia in the study group (n = 188) was iron-deficiency anemia (30.2%), followed by mixed anemia of iron, folate and vitamin-B12 deficiencies (20.7%). In the study vs. the comparison group (n = 179), the rate of pre-delivery hemoglobin > 11 g/dL was higher, and the increase in hemoglobin from intervention to delivery was greater. The ideal timing for anemia intervention for maximizing the increase in pre-delivery hemoglobin was 6-weeks or more prior to delivery. The rates of postpartum hemorrhage and blood transfusions were similar. The rate of postpartum hemoglobin < 10 g/dL was lower in the study than the comparison group. CONCLUSION Inpatient anemia investigation and treatment resulted in higher peri-delivery hemoglobin. In women randomly diagnosed with anemia at hospitalization, the rate of pre-delivery hemoglobin > 11 g/dL was increased among those who underwent a simple anemia investigation and treatment initiation.

Abstract
BACKGROUND Anemia is a hallmark of critical illness, which is largely inflammatory driven. We hypothesized that the use of anti-inflammatory agents limits the development of anemia and reduces the need for red blood cell (RBC) transfusions in patients with a hyper-inflammatory condition due to COVID-19. METHODS An observational cohort (n = 772) and a validation cohort (a subset of REMAP-CAP, n = 119) of critically ill patients with hypoxemic respiratory failure due to COVID-19 were analyzed, who either received no treatment, received steroids or received steroids plus IL-6 blocking agents. The trajectory of hemoglobin (Hb) decline and the need for RBC transfusions were compared using descriptive statistics as well as multivariate modeling. RESULTS In both cohorts, Hb level was higher in the treated groups compared to the untreated group at all time points. In the observational cohort, incidence and number of transfused patients were lower in the group receiving the combination treatment compared to the untreated groups. In a multivariate analysis controlling for baseline Hb imbalance and mechanical ventilation, receipt of steroids remained associated with a slower decline in Hb level and the combination treatment remained associated with a slower decline of Hb and with less transfusions. Results remained the same in the validation cohort. CONCLUSION Immunomodulatory treatment was associated with a slower decline in Hb level in critically ill patients with COVID-19 and with less transfusion. Findings point toward inflammation as an important cause for the occurrence of anemia in the critically ill.

Abstract
BACKGROUND The goal was to develop a risk assessment model for predicting red blood cell (RBC) transfusion in neonatal patients to assist hospital blood supply departments in providing small portions of RBCs to those requiring RBC transfusion on time. METHODS Clinical information was collected from 1,201 children admitted to the neonatal unit. Clinical factors associated with predicting RBC transfusion were screened, and prediction models were developed using stepwise and multifactorial logistic regression analyses, followed by the evaluation of prediction models using receiver operating characteristic curves, calibration curves, and decision curve analysis (DCA). RESULTS Overall, 81 neonatal patients were transfused with RBCs, and the variables of gestational age at birth, age < 1 month, receipt of mechanical ventilation, and infant anemia were included in the final prediction model. The area under the curve of the prediction model was 0.936 (0.921 - 0.949), which was significantly higher than that of the individual indicators of gestational age at birth, age at admission < 1 month, receipt of mechanical ventilation, and infant anemia (p < 0.001). DCA showed a standardized net benefit for the possible risk of infant RBC transfusion at 0.1 - 1.0. CONCLUSIONS We developed a risk assessment model to predict the risk of RBC transfusion in neonatal patients that can effectively assess the risk of RBC transfusion in children.

Abstract
BACKGROUND Transfusion of blood components has long been considered lifesaving therapy. While blood transfusion may be clinically indicated as a treatment option for some patients, the benefits of transfusion in asymptomatic, hemodynamically stable patients are questionable. PROBLEM Blood component transfusion is routinely used as a default therapy when not clinically indicated, increasing the risk of poor patient outcomes, adverse events, pressures on blood supply and availability, and increased health care costs. APPROACH Nurses have the responsibility to advocate for patients and reduce/avoid unnecessary blood transfusion through the implementation of patient blood management (PBM). The PBM paradigm includes treatment of anemia, minimizing blood loss and bleeding, optimization of coagulation, and employing true patient-centered decision making. CONCLUSIONS PBM should become the standard of care with the goal of improving health care quality and patient outcomes while using the multidisciplinary team for its implementation. As advocates for their patients, nurses can play a major role in the development, implementation, and promotion of PBM.

Abstract
BACKGROUND Despite the growing needs in nondialytic alternatives for conservative kidney management, few studies have examined the management of anemia in palliative care (PC) outpatient clinics, which represent the key point of entry for timely access to PC. OBJECTIVE A retrospective study to review for a patient-centered approach in anemia management and symptom control. RESULTS Over the study period from July 2020 to March 2023, a total of 158 patients were seen at our renal PC clinic, 47 were included in data analysis. Patients had a mean age and glomerular filtration rate of 81.3 (9.5) years and 8.6 (5.3) mL/min/1.73 m2, and 68.1% and 44.7% were receiving erythropoiesis-stimulating agents (ESAs) and iron supplements respectively, with only 4.3% of patients required transfusion over past six months. Mean hemoglobin was maintained at 9.8 (1.4) g/dL, with a mean POS-S renal score of 4.7 (3.2). Majority of patients (93.6%) had satisfactory rating on "weakness and lack of energy" item. CONCLUSION A patient-centered approach in anemia management at renal PC outpatient clinics may alleviate symptom burden and minimize transfusion requirement.

Abstract
BACKGROUND Middle uremic toxins (MUTs) can cause anemia and erythropoietin hyporesponsiveness. Theranova dialyzers may improve anemia management by removing MUTs. Hence, the impact of Theranova dialyzers on erythropoietin responsiveness was studied. METHODS This exploratory single-center prospective observational study, encompassing 50 patients undergoing dialysis with either the Theranova-400 or FX80 membrane for 6 months, involved monthly tracking of hemoglobin levels, weight-adjusted erythropoiesis-stimulating agent (w-ESA) dosing, and erythropoietin resistance index (ERI), with ESA treatment decisions guided by a proprietary algorithm. RESULTS The groups were similar in terms of demographics and baseline laboratory test results. The median hemoglobin levels, w-ESA and ERI, were found to be similar between FX80 and Theranova-400 groups at both baseline (11.06 vs 10.57, p = 0.808; 92.3 vs 105.2, p = 0.838; 8.1 vs 10.48, p = 0.876) and the end of the study (11.43 vs 11.03, p = 0.076; 48.7 vs 71.5; 4.48 vs 6.41, p = 0.310), respectively. There was a trend toward lower w-ESA and ERI at the end of the study compared to baseline in both groups, but the difference was non-significant. CONCLUSIONS Based on this study of 50 patients undergoing high-flux dialysis with near-target hemoglobin levels, switching to Theranova 400 dialyzers compared to FX80 dialyzers did not show statistically significant differences in maintaining hemoglobin levels, reducing ESA dose, or lowering ERI. The non-randomized design and small sample size limit the study's power to detect true differences. Larger, randomized trials are needed to confirm findings and definitively assess Theranova 400's benefits.

Abstract
Perioperative anemia is an independent risk factor for postoperative morbidity and mortality. However, conceptual, logistical and administrative barriers persist that hinder the widespread implementation of protocols for their management. The project coordinator convened a multidisciplinary group of 8 experienced professionals to develop perioperative anemia management algorithms, based on a series of key points (KPs) related to its prevalence, consequences, diagnosis and treatment. These KPs were assessed using a 5-point Likert scale, from "strongly disagree [1]" to "strongly agree [5]". For each KP, consensus was reached when receiving a score of 4 or 5 from at least 7 participants (>75%). Based on the 36 KPs agreed upon, diagnostic-therapeutic algorithms were developed that we believe can facilitate the implementation of programs for early identification and adequate management of perioperative anemia, adapted to the characteristics of the different institutions in our country.

Abstract
PURPOSE In adults and fetuses, N-terminal pro-B-type natriuretic peptide (NT-proBNP) is a marker of cardiac failure and myocardial remodelling. We examined the effect of anemia and intrauterine transfusion (IUT) on NT-proBNP concentrations in fetuses with anemia and established gestational age-dependent reference values of a control group. METHODS We analyzed NT-proBNP levels in anemic fetuses that underwent serial intrauterine transfusions (IUT), focusing on different causes and severity of anemia and comparing the results to a non-anemic control group. RESULTS In the control group, the average NT-proBNP concentration was 1339 ± 639 pg/ml, decreasing significantly with increasing gestational age (R = - 74.04, T = - 3.65, p = 0.001). Subjects had significantly higher NT-proBNP concentrations before initiation of IUT therapy (p < 0.001), showing fetuses with parvovirus B19 (PVB19) infection having the highest concentrations. Hydropic fetuses also showed an increased NT-proBNP concentration compared to non-hydropic fetuses (p < 0.001). During the course of therapy, NT-proBNP concentration before subsequent IUT decreased significantly from pathologically high levels, while MoM-Hb and MoM-MCA-PSV remained pathological. CONCLUSION NT-pro BNP levels in non-anemic fetuses are higher than in postnatal life, decreasing with ongoing pregnancy. Anemia is a hyperdynamic state and its severity correlates with circulating NT-proBNP levels. Highest concentrations occur in fetuses with hydrops and with PVB19 infection, respectively. Treatment by IUT leads to a normalisation of NT-proBNP concentrations, so the measurement of its levels may be useful in therapy monitoring.

Abstract
ABSTRACT Postoperative visual loss (POVL) is an infrequent yet consequential complication that can follow cardiac surgical interventions. This systematic review aims to provide a comprehensive analysis of the incidence of POVL after cardiac surgery and to delineate the associated risk factors. A comprehensive search was conducted in major medical databases for relevant studies published up to September 2022. Eligible studies reporting on the incidence of POVL and identifying risk factors in patients undergoing cardiac surgery were included. Data extraction was performed independently by two reviewers. The pooled incidence rates and the identified risk factors were synthesized qualitatively. POVL after cardiac surgery has an overall incidence of 0.015%, that is, 15 cases per 100,000 cardiac surgical procedures. Risk factors for POVL include patient characteristics (advanced age, diabetes, hypertension, and preexisting ocular conditions), procedural factors (prolonged surgery duration, cardiopulmonary bypass time, and aortic cross-clamping), anesthetic considerations (hypotension, blood pressure fluctuations, and specific techniques), and postoperative complications (stroke, hypotension, and systemic hypoperfusion). Ischemic optic neuropathy (ION) is an uncommon complication, associated with factors like prolonged cardiopulmonary bypass, low hematocrit levels, excessive body weight gain, specific medications, hypothermia, anemia, raised intraocular pressure, and micro-embolization. Diabetic patients with severe postoperative anemia are at increased risk for anterior ischemic optic neuropathy (AION). Posterior ischemic optic neuropathy (PION) can occur with factors like hypertension, postoperative edema, prolonged mechanical ventilation, micro-embolization, inflammation, hemodilution, and hypothermia.While the overall incidence of POVL postcardiac surgery remains modest, its potential impact is substantial, necessitating meticulous consideration of modifiable risk factors. Notably, prolonged surgical duration, intraoperative hypotension, anemia, and reduced hematocrit levels remain salient contributors. Vigilance is indispensable to promptly detect this infrequent yet visually debilitating phenomenon in the context of postcardiac surgical care.

Abstract
BACKGROUND Anemia can lead to secondary brain damage by reducing arterial oxygen content and brain oxygen supply. Patients with acute brain injury have impaired self-regulation. Brain hypoxia may also occur even in mild anemia. Red blood cell (RBC) transfusion is associated with increased postoperative complications, poor neurological recovery, and mortality in critically ill neurologic patients. Balancing the risks of anemia and red blood cell transfusion-associated adverse effects is challenging in neurocritical settings. METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Embase, and MEDLINE (PubMed) from inception to January 31, 2024. We included all randomized controlled trials (RCTs) assessing liberal versus restrictive RBC transfusion strategies in neurocritical patients. We included all relevant studies published in English. The primary outcome was mortality at intensive care unit (ICU), discharge, and six months. RESULTS Of 5195 records retrieved, 84 full-text articles were reviewed, and five eligible studies were included. There was no significant difference between the restrictive and liberal transfusion groups in ICU mortality (RR: 2.53, 95% CI: 0.53 to 12.13), in-hospital mortality (RR: 2.34, 95% CI: 0.50 to 11.00), mortality at six months (RR: 1.42, 95% CI: 0.42 to 4.78) and long-term mortality (RR: 1.22, 95% CI: 0.64 to 2.33). The occurrence of neurological adverse events and most major non-neurological complications was similar in the two groups. The incidence of deep venous thrombosis was lower in the restrictive strategy group (RR: 0.41, 95% CI: 0.18 to 0.91). CONCLUSIONS Due to the small sample size of current studies, the evidence is insufficiently robust to confirm definitive conclusions for neurocritical patients. Therefore, further investigation is encouraged to define appropriate RBC transfusion thresholds in the neurocritical setting.

Abstract
Anemia is the most common modifiable risk factor for postoperative morbidity and mortality. Early identification and optimal management are key to restore iron stores and ensure its resolution before surgery. Several therapies have been proposed to treat anemia in the perioperative period, such as iron supplementation and erythropoiesis-stimulating agents, though it remains unclear which is the most optimal to improve clinical outcomes. This article summarizes the most updated evidence on perioperative management of anemia and denotes differences among the international guidelines to reflect the conflicting evidence in this field and the need for further research in specific areas.

Abstract
PURPOSE Anemia reduces the blood's ability to carry and deliver oxygen. Following cardiac surgery, anemia is very common and affects up to 90% of patients. Nevertheless, there is a paucity of data examining the prognostic value of postoperative anemia. In this narrative review, we present findings from the relevant literature on postoperative anemia in cardiac surgery patients, focusing on the incidence, risk factors, and prognostic value of postoperative anemia. We also explore the potential utility of postoperative anemia as a therapeutic target to improve clinical outcomes. SOURCE We conducted a targeted search of MEDLINE, Embase, and the Cochrane Database of Systematic Reviews up to September 2022, using a combination of search terms including postoperative (post-operative), perioperative (peri-operative), anemia (anaemia), and cardiac surgery. PRINCIPAL FINDINGS The reported incidence of postoperative anemia varied from 29% to 94% across the studies, likely because of variations in patient inclusion criteria and classification of postoperative anemia. Nonetheless, the weight of the evidence suggests that postoperative anemia is common and is an independent risk factor for adverse postoperative outcomes such as acute kidney injury, stroke, mortality, and functional outcomes. CONCLUSIONS In cardiac surgery patients, postoperative anemia is a common and prognostically important risk factor for postoperative morbidity and mortality. Nevertheless, there is a lack of data on whether active management of postoperative anemia is feasible or effective in improving patient outcomes.

Abstract
Anemia is a common problem in pediatrics. The most frequent cause is iron deficiency, but it can also be associated to a constitutional or acquired pathology of the bone marrow or red blood cells. We describe a practical approach for rapidly guiding the diagnosis and management of anemia in children. It is based on the history and clinical examination, mean corpuscular volume, ferritinemia, reticulocytosis and hemolytic profile.

Abstract
INTRODUCTION The purpose of this study was to determine whether it is safe to use a conservative packed red blood cell transfusion hemoglobin threshold (5.5 g/dL) compared with a liberal transfusion threshold (7.0 g/dL) for asymptomatic patients with musculoskeletal-injured trauma out of the initial resuscitative period. METHODS This was a multicenter, prospective, nonblinded, randomized study done at three level 1 trauma centers. One hundred patients were enrolled. One patient was inappropriately enrolled, withdrawn from the study, and excluded from analysis leaving 99 patients (49 liberal and 50 conservative) with 30-day follow-up. After initial resuscitation, patients were enrolled and randomized to either a liberal or a conservative transfusion strategy. This strategy was followed throughout the index hospitalization. The primary outcome of the study was infection. Superficial infection was defined as clinical diagnosis of cellulitis or other superficial infection treated with oral antibiotics only. Deep infection was defined as clinical diagnosis of fracture-related infection requiring IV antibiotics and/or surgical débridement. RESULTS Ninety-nine patients were successfully followed for 30 days with 100% follow-up during this time. Seven infections (14%) occurred in the liberal group and none in the conservative group ( P < 0.01). Five deep infections (10%) occurred in the liberal group and none in the conservative group ( P = 0.03). Three superficial infections (6%) occurred in the liberal and none in the conservative group, which was not a significant difference ( P = 0.1). No difference was observed in length of stay between groups. DISCUSSION Transfusing young healthy asymptomatic patients with orthopaedic trauma for hemoglobin <7.0 g/dL increases the risk of infection. No increased risk of anemia-related complications was identified with a conservative transfusion threshold of 5.5 g/dL. DATA AVAILABILITY AND TRIAL REGISTRATION NUMBERS Data are available on request. IRB protocol number is 1402557771. This study was registered with Clinicaltrials.gov identifier NCT02972593. LEVEL OF EVIDENCE Level 2, unblinded prospective randomized multicenter study.

Abstract
OBJECTIVES To compare the independent and combined effects of anaemia and red blood cell transfusion on late survival after isolated coronary artery bypass grafting. METHODS Retrospective analysis of 5243 consecutive patients undergoing primary isolated coronary artery bypass grafting, performed from 2000 to 2015, in a Portuguese Academic Hospital. We identified 1649 patients with preoperative anaemia (A+) and 1422 patients who received a perioperative transfusion (T+)-the 4 possible combinations allowed for the creation of 4 subgroups (A-/T-, A-/T+, A+/T- and A+/T+). The primary endpoint was all-cause mortality at 10 years. We employed inverse probability weighting to control for confounding variables. RESULTS Thirty-one percent of the patients had preoperative anaemia, and 27.0% had at least one packed red blood cell transfusion. Inverse probability weighting was effective in eliminating differences in all significant baseline characteristics. The primary endpoint of all-cause mortality at 10 years occurred in 568 patients (20.5%) in the A-/T- group, as compared with 204 (24.4%) in the A-/T+ group (hazard ratio, 1.14; 95% confidence interval, 1.00 to 1.31; P = 0.053), 358 (33.8%) in the A+/T- group (hazard ratio, 1.53; 95% confidence interval, 1.38 to 1.71; P < 0.001), 254 (43.6%) in the A+/T+ group (hazard ratio, 2.25; 95% confidence interval, 1.97 to 2.56; P < 0.001). CONCLUSIONS This longitudinal, population-level study emphasizes the adverse long-term outcomes of preoperative anaemia and perioperative red blood cell transfusion. It stresses the importance of an evidence-based, multimodal and multidisciplinary approach to conserving blood resources and optimizing outcomes in patients at high risk for transfusion.

Abstract
OBJECTIVE In patients undergoing plastic surgery, to identify specific risk factors for anaemia and use of blood products, and assess their impact on patient outcome. METHOD For this retrospective study, data were analysed from patients who attended the Plastic Surgery Department at our hospital over a three-year period (2018 to 2020). Adult patients who presented with traumatic injuries, oncologic patients who underwent reconstructive procedures, and patients with soft tissue infections (STIs) who required plastic surgery for tissue coverage were included. Demographic and injury data, hospital admission characteristics, surgical procedures, laboratory test results, transfusion events, and in-hospital complications were extracted from patient records. RESULTS Of the 350 patients included in the study, 228 (65%) presented with trauma, 76 (22%) underwent reconstructive surgery for cancers and 46 (13%) had STIs. In total, 175 (50%) patients developed anaemia, and 37 (11%) received blood transfusions; these were 20 (54%), 5 (14%), and 12 (32%) patients in the trauma, cancer and STI groups, respectively. Associated comorbidities and upper and lower limb surgery were the most significant risk factors for anaemia, while the number of surgeries and NSTIs were identified as risk factors for blood transfusions. Direct wound closure was consistently a protective factor for both anaemia and blood transfusions. Blood transfusions were independently associated with a high risk of sepsis, wound complications, and prolonged hospital stay. CONCLUSION While transfusions are necessary and even lifesaving in surgical patients, blood is a finite resource and its use may negatively impact patient outcome. Therefore, ongoing research must focus on providing safe and restrictive clinical practices while developing sustainable and accessible alternatives.

Abstract
Placenta accreta spectrum (PAS) has become a significant life-threatening issue due to its increased incidence and associated morbidity and mortality. Pregnancy is often associated with states of anaemia, and severe maternal haemorrhage represents a major risk factor for red blood cell (RBC) transfusion. The present study retrospectively analyzed the prevalence of anaemia, transfusion requirements and outcome in women with PAS. Using data from the German Statistical Office pregnant patients with deliveries hospitalized between January 2012 and December 2021 were included. Primary outcome was the prevalence of anemia and administration of RBCs. Secondary outcome were complications in women with PAS who received RBC transfusion. In total 6,493,606 pregnant women were analyzed, of which 38,060 (0.59%) were diagnosed with PAS. The rate of anaemia during pregnancy (60.36 vs. 23.25%; p < 0.0001), postpartum haemorrhage (47.08 vs. 4.41%; p < 0.0001) and RBC transfusion rate (14.68% vs. 0.72%; p < 0.0001) were higher in women with PAS compared to women without PAS. Women with PAS who had bleeding and transfusion experienced significantly more peripartum complications than those who did not. A multiple logistic regression revealed that the probability for RBC transfusion in all pregnant women was positively associated with anaemia (OR 21.96 (95% CI 21.36-22.58)). In women with PAS, RBC transfusion was positively associated with the presence of renal failure (OR 11.27 (95% CI 9.35-13.57)) and congestive heart failure (OR 6.02 (95% CI (5.2-7.07)). Early anaemia management prior to delivery as well as blood conservation strategies are crucial in women diagnosed with PAS.

Abstract
BACKGROUND Anemia, characterized by low hemoglobin levels, is a global public health concern. Anemia is an independent factor worsening outcomes in various patient groups. Blood transfusion has been the traditional treatment for anemia; its triggers, primarily based on hemoglobin levels; however, hemoglobin level is not always an ideal trigger for blood transfusion. Additionally, blood transfusion worsens clinical outcomes in certain patient groups. This narrative review explores alternative triggers for red blood cell transfusion and their physiological basis. MAIN TEXT The review delves into the physiology of oxygen transport and highlights the limitations of using hemoglobin levels alone as transfusion trigger. The main aim of blood transfusion is to optimize oxygen delivery, necessitating an individualized approach based on clinical signs of anemia and the balance between oxygen delivery and consumption, reflected by the oxygen extraction rate. The narrative review covers different alternative triggers. It presents insights into their diagnostic value and clinical applications, emphasizing the need for personalized transfusion strategies. CONCLUSION Anemia and blood transfusion are significant factors affecting patient outcomes. While restrictive transfusion strategies are widely recommended, they may not account for the nuances of specific patient populations. The search for alternative transfusion triggers is essential to tailor transfusion therapy effectively, especially in patients with comorbidities or unique clinical profiles. Investigating alternative triggers not only enhances patient care by identifying more precise indicators but also minimizes transfusion-related risks, optimizes blood product utilization, and ensures availability when needed. Personalized transfusion strategies based on alternative triggers hold the potential to improve outcomes in various clinical scenarios, addressing anemia's complex challenges in healthcare. Further research and evidence are needed to refine these alternative triggers and guide their implementation in clinical practice.

Abstract
This study uses machine learning and population data to analyze major determinants of blood transfusion among patients with hip arthroplasty. Retrospective cohort data came from Korea National Health Insurance Service claims data for 19,110 patients aged 65 years or more with hip arthroplasty in 2019. The dependent variable was blood transfusion (yes vs no) in 2019 and its 31 predictors were included. Random forest variable importance and Shapley Additive Explanations were used for identifying major predictors and the directions of their associations with blood transfusion. The random forest registered the area under the curve of 73.6%. Based on random forest variable importance, the top-10 predictors were anemia (0.25), tranexamic acid (0.17), age (0.16), socioeconomic status (0.05), spinal anesthesia (0.05), general anesthesia (0.04), sex (female) (0.04), dementia (0.03), iron (0.02), and congestive heart failure (0.02). These predictors were followed by their top-20 counterparts including cardiovascular disease, statin, chronic obstructive pulmonary disease, diabetes mellitus, chronic kidney disease, peripheral vascular disease, liver disease, solid tumor, myocardial infarction and hypertension. In terms of max Shapley Additive Explanations values, these associations were positive, e.g., anemia (0.09), tranexamic acid (0.07), age (0.09), socioeconomic status (0.05), spinal anesthesia (0.05), general anesthesia (0.04), sex (female) (0.02), dementia (0.03), iron (0.04), and congestive heart failure (0.03). For example, the inclusion of anemia, age, tranexamic acid or spinal anesthesia into the random forest will increase the probability of blood transfusion among patients with hip arthroplasty by 9%, 7%, 9% or 5%. Machine learning is an effective prediction model for blood transfusion among patients with hip arthroplasty. The high-risk group with anemia, age and comorbid conditions need to be treated with tranexamic acid, iron and/or other appropriate interventions.

Abstract
OBJECTIVE To investigate the differences and similarities of parameters associated with anemia of inflammation between patients with stage Ⅲ periodontitis and periodontally healthy volunteers, and to explore the influence of periodontal initial therapy on those indicators. METHODS Patients with stage Ⅲ periodontitis and periodontally healthy volunteers seeking periodontal treatment or prophylaxis at Department of Periodontology, Peking University School and Hospital of Stomatology from February 2020 to February 2023 were enrolled. Their demographic characteristics, periodontal parameters (including probing depth, clinical attachment loss, bleeding index), and fasting blood were gathered before periodontal initial therapy. Three months after periodontal initial therapy, the periodontal parameters of the patients with stage Ⅲ periodontitis were re-evaluated and their fasting blood was collected again. Blood routine examinations (including white blood cells, red blood cells, hemoglobin, packed cell volume, mean corpuscular volume of erythrocytes, and mean corpuscular hemoglobin concentration) were performed. And ferritin, hepcidin, erythropoietin (EPO) were detected with enzyme-linked immunosorbent assay (ELISA). All data analysis was done with SPSS 21.0, independent sample t test, paired t test, and analysis of covariance were used for comparison between the groups. RESULTS A total of 25 patients with stage Ⅲ periodontitis and 25 periodontally healthy volunteers were included in this study. The patients with stage Ⅲ periodontitis were significantly older than those in periodontally healthy status [(36.72±7.64) years vs. (31.44±7.52) years, P=0.017]. The patients with stage Ⅲ periodontitis showed lower serum hemoglobin [(134.92±12.71) g/L vs. (146.52±12.51) g/L, P=0.002] and higher serum ferritin [(225.08±103.36) μg/L vs. (155.19±115.38) μg/L, P=0.029], EPO [(41.28±12.58) IU/L vs. (28.38±10.52) IU/L, P < 0.001], and hepcidin [(48.03±34.44) μg/L vs. (27.42±15.00) μg/L, P=0.009] compared with periodontally healthy volunteers. After adjusting the age with the covariance analysis, these parameters (hemoglobin, ferritin, EPO, and hepcidin) showed the same trends as independent-sample t test with statistical significance. Three months after periodontal initial therapy, all the periodontal parameters showed statistically significant improvement. The serum hemoglobin raised [(146.05±15.48) g/L vs. (133.77± 13.15) g/L, P < 0.001], while the serum ferritin [(128.52±90.95) μg/L vs. (221.22±102.15) μg/L, P < 0.001], EPO [(27.66±19.67) IU/L vs. (39.63± 12.48) IU/L, P=0.004], and hepcidin [(32.54±18.67) μg/L vs. (48.18±36.74) μg/L, P=0.033] decreased compared with baseline. CONCLUSION Tendency of iron metabolism disorder and anemia of inflammation was observed in patients with stage Ⅲ periodontitis, which can be attenuated by periodontal initial therapy.

Abstract
Extensive research in countries with high sociodemographic indices (SDIs) to date has shown that coronavirus disease 2019 (COVID-19) may be directly associated with more severe outcomes among patients living with haematological disorders and malignancies (HDMs). Because individuals with moderate to severe immunodeficiency are likely to undergo persistent infections, shed virus particles for prolonged periods, and lack an inflammatory or abortive phase, this represents an overall risk of morbidity and mortality from COVID-19. In cases suffering from HDMs, further investigation is needed to achieve a better understanding of triviruses and a group of related variants in patients with anemia and HDMs, as well as their treatment through vaccines, drugs, and other methods. Against this background, the present study aimed to delineate the relationship between HDMs and the novel COVID-19, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Besides, effective treatment options for HDM cases were further explored to address this epidemic and its variants. Therefore, learning about how COVID-19 manifests in these patients, along with exploiting the most appropriate treatments, may lead to the development of treatment and care strategies by clinicians and researchers to help patients recover faster.

Abstract
BACKGROUND Anaemia in pregnancy causes a significant burden of maternal morbidity and mortality in sub-Saharan Africa, with prevalence ranging from 25 to 45% in Nigeria. The main treatment, daily oral iron, is associated with suboptimal adherence and effectiveness. Among pregnant women with iron deficiency, which is a leading cause of anaemia (IDA), intravenous (IV) iron is an alternative treatment in moderate or severe cases. This qualitative study explored the acceptability of IV iron in the states of Kano and Lagos in Nigeria. METHODS We purposively sampled various stakeholders, including pregnant women, domestic decision-makers, and healthcare providers (HCPs) during the pre-intervention phase of a hybrid clinical trial (IVON trial) in 10 healthcare facilities across three levels of the health system. Semi-structured topic guides guided 12 focus group discussions (140 participants) and 29 key informant interviews. We used the theoretical framework of acceptability to conduct qualitative content analysis. RESULTS We identified three main themes and eight sub-themes that reflected the prospective acceptability of IV iron therapy. Generally, all stakeholders had a positive affective attitude towards IV iron based on its comparative advantages to oral iron. The HCPs noted the effectiveness of IV iron in its ability to evoke an immediate response and capacity to reduce anaemia-related complications. It was perceived as a suitable alternative to blood transfusion for specific individuals based on ethicality. However, to pregnant women and the HCPs, IV iron could present a higher opportunity cost than oral iron for the users and providers as it necessitates additional time to receive and administer it. To all stakeholder groups, leveraging the existing infrastructure to facilitate IV iron treatment will stimulate coherence and self-efficacy while strengthening the existing trust between pregnant women and HCPs can avert misconceptions. Finally, even though high out-of-pocket costs might make IV iron out of reach for poor women, the HCPs felt it can potentially prevent higher treatment fees from complications of IDA. CONCLUSIONS IV iron has a potential to become the preferred treatment for iron-deficiency anaemia in pregnancy in Nigeria if proven effective. HCP training, optimisation of information and clinical care delivery during antenatal visits, uninterrupted supply of IV iron, and subsidies to offset higher costs need to be considered to improve its acceptability.

Abstract
Total knee arthroplasty (TKA) is the most cost-effective, and potent method for the treatment of end-stage knee osteoarthritis. Acute normovolemic haemodilution (ANH) can effectively replace the need for allogeneic transfusions due to the high amount of bleeding during TKA. However, more studies are needed to prove the efficacy and safety of ANH and to clarify its indications in the field of knee replacement. Medical records from June 1, 2019 to June 1, 2021 were searched and grouped according to inclusion and exclusion criteria. PART I 58 patients with ANH during TKA were selected as the ANH group (n = 58), and 58 patients with allogeneic transfusion were chosen as the control group (n = 58). PART II Patients with anaemia were divided into the ANH group (n = 18) and the control group (n = 12). PART I The postoperative inflammatory index and serum albumin in the ANH group were significantly lower than those in the control group. No significant difference was observed in the theoretical loss of red blood cells, postoperative renal function, liver function, cardiac function and biochemical ion index between the two groups. The effective rate of ANH in the normal haemoglobin group was significantly lower than that in the anaemia group. PART II In patients with anaemia, the theoretical loss of red blood cells in patients with ANH was less than that in the control group. The postoperative inflammation, renal function, liver function and cardiac function in the ANH group were better than those in the control group, and no significant difference was noted in biochemical ions and nutritional status indicators. This paper shows that ANH not only can replace allogeneic transfusion in TKA, especially in patients with anaemia, but also has lower inflammatory indicators than allogeneic transfusion. From a security perspective, the body's tolerance to ANH is within the body's compensation range.

Abstract
INTRODUCTION Anemia and transfusion of blood products are risk factors associated with poor patient outcomes across all elective surgeries. Patient blood management (PBM) is a patient-centered approach to optimize patient's endogenous red cell mass, to minimize blood loss in patients undergoing surgery, and to harness and optimize patient-specific physiological tolerance to anemia. This study aimed to assess (1) the impact of PBM on blood product usage in cardiovascular surgeries in a state hospital setting, (2) cost-effectiveness of PBM with a model based on transfusion of red blood cells (RBCs) in cardiovascular surgeries, and (3) the budget impact of PBM implementation based on transfusion of RBCs. METHODS Cost-effectiveness and budget impact models, based on the numbers of avoided transfusions and avoided complications after implementation of the PBM program, were compared between pre- and post-PBM periods at the cardiovascular surgery department of Ankara Bilkent City Hospital between February 11, 2019 and July 24, 2022. The probabilities of transfusions and complications with and without PBM were taken from recent meta-analyses. Data from the Ankara Bilkent City Hospital transfusion center informed the pre- and post-PBM calculations. Costs were calculated from the Social Security Institution's perspective. RESULTS There was a 21% decrease in the use of RBCs and a 23.7% decrease in use of all blood products after the implementation of PBM. The number of RBC packs per patient reduced by 0.88 packs (21%). The cost saving from reduction of RBC transfusions per patient was 518.68 Turkish lira (TRY) and for the hospital it was 1,635,948 TRY. Fewer complications and lower costs in favor of the post-PBM arm were demonstrated in the cost-effectiveness analysis. On the basis of the budget impact model, in 20 months, the hospital's cardiovascular surgery department saved 6,596,934 TRY (€342,302). CONCLUSION This hospital-based study demonstrated that PBM is a budget-saving and cost-effective option in Turkey.

Abstract
BACKGROUND A hemoglobin (Hb) level goal of 7-8 g/dL is a standard care threshold, prompting blood transfusion. The debate over whether acute myocardial infarction (MI) patients benefit from a more liberal transfusion strategy prompted a meta-analysis of relevant trials. METHODS We performed a meta-analysis of randomized controlled trials (RCTs) comparing liberal and restrictive transfusion strategies in anemic MI patients. Primary outcomes were recurrent MI and death/MI, while secondary outcomes included stroke, revascularization, heart failure, and all-cause mortality. Due to the limited trials, we utilized the Paul-Mendele method with Hartung Knapp adjustment. RESULTS Involving 2155 patients with liberal transfusion and 2170 with conservative transfusion across four RCTs, liberal transfusion did not significantly reduce MI (relative risk [RR] 0.85; 95 % CI 0.72 - 1.02, p = 0.07) or death/MI (RR 0.88; 95 % CI 0.45 - 1.71, p = 0.57). No significant differences were observed in all-cause mortality (RR 0.82; 95 % CI 0.25 - 2.68, p = 0.63), stroke (RR 0.89; 95 % CI 0.48 - 1.64, p = 0.50), revascularization (RR 0.93; 95 % CI 0.48 - 1.80, p = 0.68), or heart failure (RR 1.14; 95 % CI 0.04 - 28.84, p = 0.88). CONCLUSION Our meta-analysis supports current medical guidelines, reinforcing the practice of limiting transfusions in acute MI patients to those with an Hb level of 7 or 8 g/dL. Liberal transfusion strategies did not show improved clinical outcomes.

Abstract
BACKGROUND Evidence for the management of moderate-to-severe postpartum anemia is limited. A randomized trial is needed; recruitment may be challenging. STUDY DESIGN AND METHODS Randomized pilot trial with feasibility surveys. INCLUSION hemoglobin 65-79 g/L, ≤7 days of birth, hemodynamically stable. EXCLUSION ongoing heavy bleeding; already received, or contraindication to intravenous (IV)-iron or red blood cell transfusion (RBC-T). Intervention/control: IV-iron; RBC-T; or IV-iron and RBC-T. PRIMARY OUTCOME number of recruits; proportion of those approached; proportion considered potentially eligible. SECONDARY OUTCOMES fatigue, depression, baby-feeding, and hemoglobin at 1, 6 and 12 weeks; ferritin at 6 and 12 weeks. Surveys explored attitudes to trial participation. RESULTS Over 16 weeks and three sites, 26/34 (76%) women approached consented to trial participation, including eight (31%) Māori women. Of those potentially eligible, 26/167 (15.6%) consented to participate. Key participation enablers were altruism and study relevance. For clinicians and stakeholders the availability of research assistance was the key barrier/enabler. Between-group rates of fatigue and depression were similar. Although underpowered to address secondary outcomes, IV-iron and RBC-T compared with RBC-T were associated with higher hemoglobin concentrations at 6 (mean difference [MD] 11.7 g/L, 95% confidence interval [CI] 2.7-20.7) and 12 (MD 12.8 g/L, 95% CI 1.5-24.2) weeks, and higher ferritin concentrations at 6 weeks (MD 136.8 mcg/L, 95% CI 76.6-196.9). DISCUSSION Willingness to participate supports feasibility for a future trial assessing the effectiveness of IV-iron and RBC-T for postpartum anemia. Dedicated research assistance will be critical to the success of an appropriately powered trial including women-centered outcomes.

Abstract
Therapeutic plasma exchange is known to be an extracorporeal treatment procedure with few adverse effects. Anemia in chronically exchanged patients is not a well-recognized adverse effect. Our aim is to find if adult patients develop anemia while undergoing prolonged TPE treatments and to determine the time of onset of anemia. We retrospectively reviewed all outpatients that have undergone TPE at least once a week from July 2017 to March 2020. Kaplan-Meier time-to-event analysis was employed to calculate the time taken for development of anemia and time to reduction of hemoglobin by 1 g/dL from baseline in uncensored patients. A total of 14 patients met inclusion criteria receiving chronic TPE for neurological disorders including myasthenia gravis (MG). Eleven patients had once a week procedure. Study patients underwent a total of 113 (IQR, 84-227) TPE procedures and the duration of TPE was 4 (IQR, 2-6.5) years. Anemia was prevalent in 29% of this patient cohort before the initiation of TPE with a median hemoglobin of 9.4 (IQR, 8.1-11.0) g/dL. All patients regardless of hemoglobin levels prior to therapy had a decrease of 1 g/dL in hemoglobin in 6 (IQR, 3-8) weeks after initiation of chronic TPE. Anemia occurred in all non-anemic patients who underwent chronic TPE within a short period of ten weeks. Patients who were moderately anemic prior to initiation of TPE progressed to severe anemia within six weeks of TPE. Our results suggest that anemia is a consequence of chronic TPE. Baseline and follow-up laboratory studies are vital for early diagnosis.

Abstract
INTRODUCTION Maternal red blood cell alloimmunization during pregnancy can lead to hemolysis and various degrees of fetal anemia, which can be treated with intrauterine blood transfusion (IUT) to prevent adverse outcomes. Knowledge about fetal myocardial function and adaptation is limited. The aim of the present study was to measure fetal atrioventricular plane displacement before and after IUT and compare these measurements with previously established reference ranges. MATERIAL AND METHODS An observational study was conducted on pregnant women affected by red blood cell alloimmunization. Fetal echocardiography was performed before and after IUT. The atrioventricular plane displacement of the left and right ventricular walls and interventricular septum, described as mitral, septal, and tricuspid annular plane systolic excursion (MAPSE, SAPSE, and TAPSE, respectively), was assessed using color tissue Doppler imaging with automated analysis software. A Mann-Whitney U test was used to compare the z scores to the normal mean before and after IUT. RESULTS Twenty-seven fetuses were included. The mean z score for pre-IUT MAPSE was significantly increased compared with the reference ranges, +0.46 (95% confidence interval [CI] +0.17 to +0.75; p = 0.039), while the mean z scores for post-IUT SAPSE and TAPSE were significantly decreased, -0.65 (95% CI -1.11 to -0.19; p < 0.001) and -0.60 (95% CI -1.04 to -0.17; p = 0.003), respectively. The difference in atrioventricular plane displacement z scores before and after IUT was statistically significant in all three locations. The median difference between the pre-IUT and post-IUT z scores was -0.66 (95% CI -1.03 to -0.33, p < 0.001) for MAPSE, -1.05 (95% CI -1.43 to -0.61, p < 0.001) for SAPSE, and -0.60 (95% CI -1.19 to -0.01, p = 0.046) for TAPSE. CONCLUSIONS This study suggests that atrioventricular plane displacement, when determined using automated analysis software, may represent a quantitative parameter, describing fetal myocardial function and adaptation before and after IUT.

Abstract
BACKGROUND PBM metrics play a crucial role in assessing and monitoring the effectiveness of PBM programs in healthcare settings. The present study aimed to assess the indicators to achieve effective enforcement of PBM at a tertiary care referral hospital. SUBJECTS AND METHOD A prospective observational study was conducted on patients admitted for elective surgery at a tertiary care referral centre. PBM metrics were developed and assessed for various parameters, including documentation, patient evaluation, blood ordering schedule, and appropriateness. Experts in transfusion medicine and haematology checked content validity. Eleven different parameters were analysed, and a score was assigned based on the performance. The outcome was categorized as poor, satisfactory, or good. RESULTS The study included 612 patients meeting the inclusion criteria and recruited from Orthopaedics, General Surgery, OBG, Urology, and ENT departments. All departments completed pre-operative anaemia tests, with General Surgery and Orthopaedics conducting the most red cell transfusions. During the study, all of the blood units were used, and there was no waste. The C/T ratio was greater in the Departments of General Surgery, Urology, and Otorhinolaryngology. Pre-operative anaemia was found in 44.12% of patients, 44 patients had red cell transfusions, with 65% getting single-unit PRBC transfusions. All departments received a PBM score between 17-19, showing adequate PBM but with room for improvement. CONCLUSION The current study utilized Patient Blood Management (PBM) metrics to critically assess the existing practices and identify the key gaps and areas for improvement in a tertiary care centre.

Abstract
BACKGROUND Anemia in myelodysplastic syndromes (MDS) is associated with poorer health-related quality of life (HRQoL) and physical function, and is frequently treated with transfusions. The current common practice of transfusing multiple red blood cells (RBC) units every 2-4 weeks may result in peaks/troughs in hemoglobin (Hb) level, yet maintaining a stable Hb may better improve HRQoL. We describe a study protocol aiming to investigate the feasibility of weekly low-dose RBC transfusion in MDS patients, including assessing HRQoL and physical function outcomes. STUDY DESIGN AND METHODS In this n-of-1 pilot study, patients receive two treatment arms, with randomly allocated treatment sequence: arm A (patient's usual transfusion schedule) and arm B (weekly transfusion, individualized per patient). To facilitate timely delivery of weekly transfusion, extended-matched RBCs are provided, with transfusion based upon the previous week's Hb/pre-transfusion testing results to eliminate delays of awaiting contemporaneous cross-matching. Primary outcome is the feasibility of delivering weekly transfusion. Secondary outcomes include HRQoL, functional activity measurements, RBC usage, and alloimmunization rates. A qualitative substudy explores patient and staff experiences. RESULTS The trial is open in Australia, Netherlands, and UK. The first patient was recruited in 2020. Inter-country differences in providing RBCs are observed, including patient genotyping versus serological phenotyping to select compatible units. DISCUSSION This pilot trial evaluates a novel personalized transfusion approach of weekly matched RBC transfusion and challenges the dogma of current routine pre-transfusion matching practice. Findings on study feasibility, HRQoL, and physical functional outcomes and the qualitative substudy will inform the design of a larger definitive trial powered for clinical outcomes.

Abstract
AIM Paediatric-preoperative anaemia management is challenging in settings where clinical judgment is used to diagnose anaemia owing to a lack of timely, affordable preoperative haemoglobin testing. We analysed anaemia management in such a setting after the introduction of point-of-care bedside haemoglobin testers. METHOD 1033 children who underwent surgery at a hospital in Bangladesh were included in this study. 569 underwent major surgery, and 464 underwent minor surgery and belonged to predominantly ASA category 1 or 2. RESULTS 940/1033 children underwent preoperative anaemia testing. Average haemoglobin was 11.7 g/dL. 103/1033 children were deemed clinically anaemic. However, 285 children were found to have anaemia based on bedside testing. Sensitivity of clinical judgement was 33.68% (95 % CI 28.22%-39.49%), and the specificity was 99.08% (95 % CI 98.02%-99.66%). 63/1033 had preoperative anaemia treatment, of whom 60 underwent transfusion. Subgroup analysis of children with haemoglobin <10 g/dL (n = 124) was done to compare conservative vs liberal transfusion strategy. 43/124 of this subset was transfused. Average length of stay for those transfused was 11.7 days, and those who weren't was 9.9 days (p = 0.087). 4 patients in the transfused subgroup required post-op ICU, and only 1 patient in the conservatively managed arm required ICU (p = 0.048). CONCLUSION This study demonstrates the positive impact of bedside haemoglobin testers as they have resulted in a significantly higher proportion of children diagnosed with anaemia at a fraction of the cost and logistics involved in laboratory testing. Further research on haemoglobin thresholds is required to understand the safety and long-term impact of restrictive transfusion in the surgical context. LEVEL OF EVIDENCE 2c (Grading as per the Oxford Centre for Evidence Based Medicine).

Abstract
BACKGROUND The appropriate use of obstetric blood transfusion is crucial for patients with placenta previa and prenatal anemia. This retrospective study aims to explore the correlation between prenatal anemia and blood transfusion-related parameters in this population. METHODS We retrieved the medical records of consecutive participants who were diagnosed with placenta previa and underwent cesarean section in our hospital. We compared the baseline demographics and clinical characteristics of patients with and without anemia. The correlation between prenatal anemia and obstetric blood transfusion-related parameters was evaluated using multivariate regression analysis. RESULTS A total of 749 patients were enrolled, with a mean prenatal hemoglobin level of 10.87 ± 1.37 g/dL. Among them, 54.87% (391/749) were diagnosed with anemia. The rate of obstetric blood transfusion was significantly higher in the anemia group (79.54%) compared to the normal group (44.41%). The median allogeneic red blood cell transfusion volume in the anemia group was 4.00 U (IQR 2.00-6.00), while in the normal group, it was 0.00 U (IQR 0.00-4.00). The prenatal hemoglobin levels had a non-linear relationship with intraoperative allogeneic blood transfusion rate, massive blood transfusion rate, red blood cell transfusion units, and fresh plasma transfusion volume in patients with placenta previa, with a threshold of 12 g/dL. CONCLUSIONS Our findings suggest that prenatal anemia is associated with a higher rate of blood transfusion-related parameters in women with placenta previa when the hemoglobin level is < 12 g/dL. These results highlight the importance of promoting prenatal care in placenta previa patients with a high requirement for blood transfusion.

Abstract
ABSTRACT With the global growing older adult population, clinicians face the common, yet complex challenge of how to evaluate and manage anemia in this population. Older age predisposes to common causes of anemia such as nutritional deficiencies, inflammatory disorders, chronic kidney disease, and hematologic malignancies. Failure to diagnose and appropriately manage anemia may result in decreased quality of life, impaired cognition, impaired mobility, and increased mortality. Anemia diagnosis in older adults presents a diagnostic conundrum because anemia may have a single cause, may be multifactorial, or may have no apparent cause even after an extensive evaluation. We believe a systematic approach to diagnosis ensures appropriate testing and avoids the pitfall of undertreatment and overtreatment. In this article we present our recommended approach through common scenarios for the management of anemia in the older adult.

Abstract
BACKGROUND The prevalence of anemia is high, especially in obstetrics. There is large evidence, that anemia during pregnancy is associated with increased maternal morbidity and mortality. Anemia and peripartum hemorrhage remain the main causes for transfusion of red blood cells (RBC). Patient Blood Management (PBM) reduces the need for RBC transfusion significantly. The present study retrospectively analyzed the impact and prevalence of anemia and RBC transfusion on pregnant women. MATERIALS AND METHODS Data were retrieved from the German Statistical Office on pregnant women who delivered in hospital between January 1st 2011 and December 31st 2020. The prevalence of anemia, peripartum hemorrhage, comorbidities, administration of blood products and complications were analyzed. RESULTS A total of 6,356,046 pregnant women were analyzed of whom 78,257 (1.23%) received RBC transfusion (RBC transfusion group) and 6,277,789 (98.77%) did not receive RBC transfusion (non-RBC transfusion group). In all women analyzed anemia rate was 23.74%. The rates of anemia during pregnancy (70.39 vs 23.15%; p<0.0001), postpartum hemorrhage (41.42 vs 4.35%; p<0.0001), hospital length of stay (127.5 vs 87.08 hours; p<0.0001) and single complications were higher in women with RBC transfusion compared to women without RBC transfusion. DISCUSSION The prevalence of anemia and the increased risk for RBC transfusion show that there is great potential for effective implementation of PBM in obstetrics. The treatment of anemia during pregnancy and reduction of RBC transfusions will decrease maternal morbidity and mortality.

Abstract
Anaemia is common in end-stage heart failure patients supported with continuous flow left ventricular assist device (CF-LVAD) and is associated with adverse outcomes such as heart failure readmission. This study evaluates the haemodynamic effects of anaemia on cardiac function and cerebral blood flow in heart failure patients supported with CF-LVAD using computational simulations. A dynamic model simulating cardiac function, systemic, pulmonary and cerebral circulations, cerebral flow autoregulatory mechanisms and gas contents in blood was used to evaluate the effects of anaemia and iron deficiency in heart failure and during CF-LVAD support. CF-LVAD therapy was simulated by a model describing HeartMate 3. Anaemia and iron deficiency were simulated by reducing the haemoglobin level from 15 to 9 g/dL and modifying scaling coefficients in the models simulating heart chamber volumes. Reduced haemoglobin levels decreased the arterial O2 content, which increased cerebral blood flow rate by more than 50% in heart failure and during CF-LVAD assistance. Reduced haemoglobin levels simulating anaemia had minimal effect on the arterial and atrial blood pressures and ventricular volumes. In contrast, iron deficiency increased end-diastolic left and right ventricular diameters in heart failure from 6.6 cm to 7 cm and 2.9 cm to 3.1 cm and during CF-LVAD support from 6.1 to 6.4 cm and 3.1 to 3.3 cm. The developed numerical model simulates the effects of anaemia in failing heart and during CF-LVAD therapy. It is in good agreement with clinical data and can be utilised to assess CF-LVAD therapy.

Abstract
Red blood cell (RBC) transfusion therapy is often performed in patients with acute heart failure (AHF) and anemia; however, its impact on subsequent cardiovascular events is unclear. We examined whether RBC transfusion influences major adverse cardiovascular events (MACE) after discharge in patients with AHF and anemia.We classified patients with AHF and anemia (nadir hemoglobin level < 10 g/dL) according to whether they received RBC transfusion during hospitalization. The endpoint was MACE (composite of all-cause death, non-fatal acute coronary syndrome/stroke, or heart failure readmission) 180 days after discharge. For survival analysis, we used propensity score matching analysis with the log-rank test. As sensitivity analysis, we performed inverse probability weighting analysis and multivariable Cox regression analysis.Among 448 patients with AHF and anemia (median age, 81 years; male, 55%), 155 received RBC transfusion and 293 did not. The transfused patients had worse clinical features than the non-transfused patients, with lower levels of nadir hemoglobin and serum albumin and a lower estimated glomerular filtration rate. In the propensity-matched cohort of 87 pairs, there was no significant difference in the MACE-free survival rate between the 2 groups (transfused, 73.8% vs. non-transfused, 65.3%; P = 0.317). This result was consistent in the inverse probability weighting analysis (transfused, 76.0% vs. non-transfused, 68.7%; P = 0.512), and RBC transfusion was not significantly associated with post-discharge MACE in the multivariable Cox regression analysis (adjusted hazard ratio: 1.468, 95% confidence interval: 0.976-2.207; P = 0.065).In conclusion, this study suggests that RBC transfusions for anemia may not improve clinical outcomes in patients with AHF.

Abstract
BACKGROUND Noninvasive mechanical ventilation (NIV) is recommended as the initial mode of ventilation to treat acute respiratory failure in patients with AECOPD. The Noninvasive Ventilation Outcomes (NIVO) score has been proposed to evaluate the prognosis in patients with AECOPD requiring assisted NIV. However, it is not validated in Chinese patients. METHODS We used data from the MAGNET AECOPD Registry study, which is a prospective, noninterventional, multicenter, real-world study conducted between September 2017 and July 2021 in China. Data for the potential risk factors of mortality were collected and the NIVO score was calculated, and the in-hospital mortality was evaluated using the NIVO risk score. RESULTS A total of 1164 patients were included in the study, and 57 patients (4.9%) died during their hospital stay. Multiple logistic regression analysis revealed that age ≥75 years, DBP <60 mmHg, Glasgow Coma Scale ≤14, anemia and BUN >7 mmol/L were independent predictors of in-hospital mortality. The in-hospital mortality was associated with an increase in the risk level of NIVO score and the difference was statistically significant (p < .001). The NIVO risk score showed an acceptable accuracy for predicting the in-hospital mortality in AECOPD requiring assisted NIV (AUC: 0.657, 95% CI: 0.584-0.729, p < .001). CONCLUSION Our findings identified predictors of mortality in patients with AECOPD receiving NIV, providing useful information to identify severe patients and guide the management of AECOPD. The NIVO score showed an acceptable predictive value for AECOPD receiving NIV in Chinese patients, and additional studies are needed to develop and validate predictive scores based on specific populations.

Abstract
OBJECTIVE Preoperative anemia has been identified as a modifiable risk factor for multiple adverse outcomes. In real clinical practice, considering treatment of anemia would increase costs and delay surgery. Patients undergoing total hip arthroplasty (THA) with mild anemia are usually neglected and still underdiagnosed or inadequately treated. This study investigated the effects of preoperative borderline anemia and anemia intervention before THA on perioperative outcomes. METHODS We screened 706 patients from those receiving THA at our hospital from January 2020 to January 2022, with 112 in the borderline anemia group and 594 in the non-anemia group. The cohort for this retrospective study was created by using propensity score matching (PSM) and subgroup analysis. The primary outcome was perioperative blood loss, while secondary outcomes were the rate of allogeneic blood transfusion and human serum albumin transfusion, perioperative laboratory indicators, postoperative length of stay, and complications. The independent sample t-test and the Mann-Whitney U-test were used to analyze continuous data, and the Pearson χ2 -test or the Fisher exact test was used to analyze categorical variables. RESULTS After PSM, there was no significant difference in perioperative blood loss between patients in the borderline anemia group and the non-anemia group. The primary outcomes of hidden (p = 0.004) and total (p = 0.005) blood loss were significantly lower in the intervention group than in the control group. No statistical differences were found in allogeneic blood transfusion, human serum albumin transfusion, postoperative length of stay, or complications (p > 0.05). CONCLUSIONS Anemia treatments for patients with borderline anemia before THA significantly reduced hidden blood loss and total blood loss in the perioperative period and decreased the drop of hemoglobin and hematocrit without increasing postoperative complications.

Abstract
Jehovah's Witnesses is a Christian denomination widely recognized for their steadfast refusal of blood transfusions, even when facing severe anemia. We describe a unique case of a 42-year-old Jehovah's Witness woman with severe iron deficiency anemia. She necessitated surgical correction of a malpositioned gastric band within the context of a complex necrotizing aspiration pneumonia secondary to esophageal obstruction. Medical management of this severe anemia has been a challenge as traditional approaches, like a blood transfusion, are not possible. Instead, a multifaceted approach has been described with intravenous iron infusions, recombinant human erythropoietin, vitamin B12, folate, and vitamin C administration. We emphasize the lack of consensus on guideline protocols regarding management of severe anemia for Jehovah's Witness patients and the subsequent need for more investigation into that matter. It also underscores the significance of respecting patient autonomy through close collaboration between patients and their health care providers to ensure effective patient-centered care.
