Abstract
Postoperative anemia is a complex clinical issue that requires attention due to its ramifications on the patient's recovery and prognosis. Originating from multiple determinants, such as intraoperative blood loss, hemolysis, nutritional deficiencies, systemic inflammation and impact on the bone marrow, postoperative anemia has varied and often challenging presentations. Patients undergoing major surgical procedures, in particular, are susceptible to developing anemia due to the considerable associated blood loss. Accurate diagnosis plays a crucial role in the approach, requiring meticulous hematological analysis, including hemoglobin, hematocrit and reticulocyte count, as well as an in-depth investigation of the underlying causes. An additional challenge arises in the form of the excessive practice of phlebotomy during hospitalization for clinical monitoring. Although it is essential to assess the progression of anemia, frequent removal of blood may contribute to iatrogenic anemia, further delaying recovery and possibly increasing susceptibility to infection.

Abstract
Evidence-based medicine is considered 1 of the 15 great inventions in medicine. It aims to remove bias in medical decision-making as much as possible through a rigorous process. In this article, the principles of evidence-based medicine are illustrated using the case of patient blood management (PBM). Acute or chronic bleeding, iron deficiency, and renal and oncological diseases may lead to preoperative anemia. To compensate for severe and life-threatening blood loss during surgery, doctors transfuse red blood cells (RBCs). PBM is an approach to take care of patients at risk for anemia, which includes detecting and treating anemia before surgery. Alternative interventions to treat preoperative anemia are the use of iron supplementation with or without erythro-stimulating agents (ESAs). The best available scientific evidence today indicates that preoperative intravenous (IV) or oral iron monotherapy may not be effective to reduce RBC utilization (low-certainty evidence). Preoperative IV iron supplementation in addition to ESAs is probably effective to reduce RBC utilization (moderate-certainty evidence), whereas oral iron supplementation in addition to ESAs may be effective to reduce RBC utilization (low-certainty evidence). The adverse events of preoperative oral/IV iron and/or ESAs and their impact on patient-important outcomes (morbidity, mortality, quality of life) remain unclear (very low-certainty evidence). Since PBM is a patient-centered approach, emphasis on monitoring and evaluation of patient-important outcomes in future research is urgently needed. Finally, the cost-effectiveness of preoperative oral/IV iron monotherapy is unproven, whereas preoperative oral/IV iron in addition to ESAs is extremely cost-ineffective.

Abstract
Background Parenteral iron preparations, like ferric carboxymaltose (FCM), are commonly used to manage moderate-to-severe iron deficiency anemia (IDA). Real-world data on efficacy and safety of FCM is limited in India. Methods A retrospective, observational and real-world study was conducted to assess the efficacy and safety of FCM in adolescents and adults with IDA across 269 centers in India. Data was retrieved from medical records of patients who received FCM for management of IDA. Physicians’ clinical assessment of efficacy and safety of FCM was also assessed. Data were analyzed for hematological parameters at baseline and at 4 ± 1 week for study population, and for severity of anemia. Results In 1800 patients with IDA, intravenous FCM resulted in a significant increase in hemoglobin (Hb) of 2.76 g/dL, serum ferritin of 35.85 µg/L, red blood cell (RBC) count, hematocrit, mean corpuscular volume (MCV), and mean corpuscular hemoglobin (MCH) (P < 0.001 for all) at 4 ± 1 week as compared to baseline. In subjects with severe IDA, an increase in Hb was of 3.31 g/dL, serum ferritin increased of 35.84 µg/L, RBC count, hematocrit and MCH improved significantly (P < 0.001 for all). In subjects with moderate IDA, Hb (increase of 2.63 g/dL), serum ferritin (increase of 35.92 µg/L), RBC count, hematocrit, MCV, and MCH improved significantly (P < 0.001 for all). In subjects with mild IDA, only the mean Hb values at 4 weeks were significantly higher (P < 0.001; increased by 1.89 g/dL). Physicians rated efficacy of FCM as very good to good in 97.5% of patients. Similarly, safety of FCM was rated very good to good in 97.2% subjects. Conclusion FCM efficiently, safely and quickly corrects moderate-to-severe anemia in Indian patients in a short span of 4 weeks. Physicians’ positive clinical impression of efficacy and safety supports clinical usage of FCM in real-world scenario. ![]()

Abstract
Objective The present study attempted to predict blood transfusion risk in spinal tuberculosis surgery by using a novel predictive nomogram. Methods The study was conducted on the clinical data of 495 patients (167 patients in the transfusion group and 328 patients in the non-transfusion group) who underwent spinal tuberculosis surgery in our hospital from June 2012 to June 2021. The least absolute shrinkage and selection operator (LASSO) and multivariable logistic regression analyses were used to screen out statistically significant parameters, which were included to establish a novel predictive nomogram model. The receiver operating characteristic (ROC) curve, calibration curves, C-index, and decision curve analysis (DCA) were used to evaluate the model. Finally, the nomogram was further assessed through internal validation. Results The C-index of the nomogram was 0.787 (95% confidence interval: 74.6%–.82.8%). The C-value calculated by internal validation was 0.763. The area under the curve (AUC) of the predictive nomogram was 0.785, and the DCA was 0.01–0.79. Conclusion A nomogram with high accuracy, clinical validity, and reliability was established to predict blood transfusion risk in spinal tuberculosis surgery. Surgeons must prepare preoperative surgical strategies and ensure adequate availability of blood before surgery.

Ikeda T, Terada R, Nagura Y, Okazaki H. High-dose intravenous iron supplementation after preoperative autologous blood donation is useful to prevent post-donation/preoperative anemia. Transfus Apher Sci 2021; 61:103348. [PMID: 35012842 DOI: 10.1016/j.transci.2021.103348] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 12/15/2021] [Accepted: 12/26/2021] [Indexed: 11/18/2022]
Abstract
To estimate the effectiveness of high-dose intravenous (IV) iron supplementation for iron deficiency anemia after preoperative autologous blood donation (PAD), 155 donors who visited the donation office of the University of Tokyo Hospital from December 2020 to June 2021 and showed suspected post-donation anemia were analyzed. The participants were treated with high-dose intravenous (IV) iron supplementation (high-dose group, n = 30) or a combination of low-dose IV iron and oral iron supplementation (low-dose group, n = 125). The preoperative hemoglobin (Hb) and Hb decreasing ratios during PAD (ΔHb) were compared between the two groups. Multivariate linear regression analyses were also performed to identify the confounding factors associated with preoperative Hb and ΔHb as well as high-dose IV iron supplementation. Preoperative Hb level was slightly higher in the high-dose group than in the low-dose group (12.1 ± 1.1 vs. 11.9 ± 1.1 g/dL, p = 0.27). ΔHb was significantly higher in the high-dose group than in the low-dose group (3.7 % ± 8.8 % vs. 7.7 % ± 6.5 %, p = 0.011). On the multivariate linear regression analyses, high-dose IV iron supplementation was significantly associated with higher preoperative Hb and lower ΔHb levels (p = 0.021 and 0.017, respectively) as well as the donation available period (period from the first visit to the donation office to the operation) and administration of erythropoiesis-stimulating agents. High-dose IV iron supplementation after PAD will be useful in the treatment of post-donation anemia.

Predictors for Perioperative Blood Transfusion in Patients Undergoing Open Cystectomy and Urinary Diversion and Development of a Nomogram: An Observational Cohort Study. J Clin Med 2021; 10:jcm10132797. [PMID: 34202030 PMCID: PMC8267645 DOI: 10.3390/jcm10132797] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 06/10/2021] [Accepted: 06/22/2021] [Indexed: 12/19/2022] Open
Abstract
Open radical cystectomy is associated with a substantial rate of perioperative blood transfusion. Early detection of potentially modifiable perioperative factors could reduce the need for perioperative blood transfusion and thus positively impact the outcome. We conducted an observational, single-center cohort study of 1168 patients undergoing cystectomy. Perioperative blood transfusion was defined as the need for packed red blood cells and/or fresh frozen plasma units within the first 24 h after the initiation of surgery. Multiple logistic regression analysis was performed to model the association between risk factors and blood transfusion, and a nomogram was developed. Blood transfusion occurred in 370/1168 patients (31.7%). Significant predictors were age (OR: 1.678, (95% CI: 1.379–2.042); p < 0.001), blood loss ratio (6.572, (4.878–8.853); p < 0.001), preoperative hemoglobin (0.316, (0.255–0.391); p < 0.001), tumor stage (2.067, (1.317–3.244); p = 0.002), use of oral anticoagulants (2.70, (1.163–6.270), p = 0.021), and interaction between female sex and blood loss ratio (1.344, (1.011–1.787); p = 0.042). Of the major predictors found to affect perioperative blood transfusion, two can be influenced: blood loss ratio by meticulous surgery and hemoglobin by preoperative optimization. Others such as age or advanced disease are not modifiable. This emphasizes the importance of optimal management of patients prior to surgery.
