Surg Oncol 2024; 55:102101. [PMID: 39018867 DOI: 10.1016/j.suronc.2024.102101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2024] [Revised: 05/05/2024] [Accepted: 05/27/2024] [Indexed: 07/19/2024]
Abstract
INTRODUCTION Giant cell tumors of the bone (GCTB) are aggressive neoplasms, with rare occurrences in the posterior pelvis and sacral area. Surgical challenges in this region include the inability to apply a tourniquet and limited cementation post-curettage due to proximity to neurovascular structures, leading to potential complications. This case-control study explores the impact of preoperative embolization on GCTB located in the iliosacral region. METHODS Five surgeries (January-December 2021) for pelvic GCTB (3 sacrum, 2 posterior ilium) were performed on four patients. Diagnosis was confirmed through preoperative CT-guided biopsies. One surgery involved curettage with PMMA cement filling, while four surgeries had curettage without cavity filling. Preoperative embolization of the tumor feeding vessel occurred approximately 16 h before surgery in two cases. Denosumab treatment was not administered. RESULTS Tumor volume, assessed by preoperative MRI, was comparable between patients with and without preoperative embolization (p = .14). Surgeries without embolization had a mean intraoperative blood loss of 3250 ml, erythrocyte transfusion volume of 1125 ml, and a mean surgical time of 114.5 min for two surgeries. Surgeries with preoperative embolization showed a mean intraoperative blood loss of 1850 ml, no erythrocyte transfusion requirement, and a mean surgical time of 68 min. CONCLUSION Curettage of GCTB in the posterior pelvis and sacrum presents challenges, with significant intraoperative blood loss impacting surgical time and transfusion needs. Preoperative embolization may be beneficial in reducing blood loss during surgery in these cases.

Acta Anaesthesiol Scand 2024. [PMID: 38986536 DOI: 10.1111/aas.14495] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 06/10/2024] [Accepted: 06/22/2024] [Indexed: 07/12/2024]
Abstract
BACKGROUND Pre-operative iron deficiency anaemia (IDA) is common in patients undergoing elective major abdominal surgery and is associated with increased risk of perioperative complications. However, widespread implementation of pre-operative anaemia management is lacking. Guidelines recommend investigation of anaemia preferably 4-6 weeks before surgery to allow time for correction. However, this is not always feasible in abdominal cancer surgery with short time to surgery and may be influenced by concomitant chemotherapy. The objective of this study was to assess the efficacy of implementing a pre-operative screening and treatment programme for IDA in elective abdominal cancer surgery patients, with short duration to surgery and concomitant use of chemotherapy. METHODS All patients scheduled for elective abdominal cancer surgery with IDA were included. Anaemia was defined according to the World Health Organization-criteria and iron deficiency as a transferrin saturation <0.20. The primary outcome was change in haemoglobin (Hb) between iron infusion and surgery in patients receiving pre-operative intravenous iron infusion. RESULTS Of 178 diagnosed IDA patients 134 (75%) received intravenous iron, 103 pre-operatively (58%) at median day 17 (interquartile range: 9-27) before surgery while 31 (17%) received post-operative intravenous iron treatment. The pre-operative Hb increased 0.89 g/dL (95% CI: 0.64-1.13, p < .001) compared to a decrease of 0.4 g/dL (95% CI: 0.19-0.58, p < .001) in 75 patients not treated pre-operatively. Patients diagnosed with severe anaemia had the largest pre-operative Hb increase. Iron infusion >2 weeks pre-operatively resulted in a greater Hb increment of 1.13 g/dL (95% CI: 0.81-1.45) compared to iron infusion ≤2 weeks before surgery 0.48 g/dL (95% CI: 0.16-0.81). Hb increased by 0.64 g/dL (95% CI 0.19-1.21) in patients receiving chemotherapy ≤31 days prior to surgery. CONCLUSION In patients scheduled for abdominal cancer surgery, including in patients with concomitant chemotherapy, pre-operative IDA management is feasible and results in a significant pre-operative Hb increase compared to patients not treated. On the day of surgery 25% patients treated pre-operatively were no longer anaemic.

Abstract
INTRODUCTION Preoperative anemia is an independent risk factor of complications after primary total hip arthroplasty (THA). Currently used hemoglobin thresholds are not developed for risk stratification of arthroplasty patients and do not provide surgery-specific information on postoperative complication risk. Thus, we aimed to calculate THA-specific preoperative hemoglobin strata that observe the likelihood of 90-day blood transfusion and determine whether these strata are associated with increased risk of 90-day complications and 2-year prosthetic joint infection (PJI). METHODS A retrospective cohort analysis identified 56,101 patients who underwent primary THA from 2013 to 2022. Using the lowest hemoglobin value for each patient one month before THA, stratum-specific likelihood ratio (SSLR) analysis calculated sex-based hemoglobin strata associated with the likelihood of 90-day postoperative blood transfusion. Propensity score matching was performed. Incidence rates and risk of 90-day major complications and 2-year PJI were observed for each identified preoperative hemoglobin stratum. RESULTS SSLR analysis identified five male (strata, likelihood ratio [<10.4 g/dL, 12.5; 10.5 to 11.4 g/dL, 8.0; 11.5 to 12.4 g/dL, 2.4; 12.5 to 13.4 g/dL, 1.3; 13.5 to 13.9 g/dL, 0.5]) and five female (<8.9 g/dL, 10.7; 9.0 to 10.9 g/dL, 4.0; 11.0 to 11.4 g/dL, 2.0; 12.0 to 12.9 g/dL, 1.0; 13.0 to 13.4 g/dL, 0.6) preoperative hemoglobin strata associated with varying likelihoods of 90-day blood transfusion after THA. After matching in both male and female cohorts, as the calculated preoperative hemoglobin strata decreased, the relative risk of overall 90-day major complications and 2-year PJI increased incrementally (all P < 0.05). CONCLUSION SSLR analysis established THA-specific sex-based preoperative hemoglobin strata that observe the likelihood of 90-day blood transfusion and predict the risk of 90-day medical complications and 2-year PJI. These strata are a first of their kind in THA research. While preoperatively optimizing patients, we recommend using these hemoglobin thresholds to help guide decisions on presurgery anemia optimization and to reduce the need for postoperative blood transfusion.

Abstract
BACKGROUND Angiosarcoma of the adrenal gland is a very rare malignant vascular neoplasm. The clinical symptoms are atypical or completely absent. Angiosarcomas of the adrenal gland are therefore often discovered incidentally, and the diagnosis is made histologically after resection. CASE PRESENTATION A 46-year-old white Spanish male who was a previous smoker and nondrinker and was slightly overweight (92 kg, 176 cm, body mass index 29.7 kg/m2) with no relevant medical history presented to the internal medicine emergency department of our hospital with an unclear 12 cm tumor of the right adrenal gland. Prior to the computed tomography scan, he had had persistent evening fevers for 4 months and unintentional weight loss of 5 kg. The laboratory results showed anemia and an elevated C-reactive protein, but no hormone production. We performed an open adrenalectomy of the right adrenal gland. Finally, the histologic findings revealed an angiosarcoma of the adrenal gland. CONCLUSION Even though angiosarcomas of the adrenal gland are rare, the differential diagnosis of an angiosarcoma should be considered if a malignant tumor of the adrenal gland is suspected. Treatment decisions should be made on an interdisciplinary basis and preferably in a specialized center. Owing to the rarity of angiosarcomas of the adrenal gland, it is necessary to continue to share clinical experience to gain a better understanding of this particular tumor entity.

Abstract
Iron deficiency anemia (IDA) continues to be a global public health problem. Oral iron is the universally accepted first-line therapy, and most children have a prompt and favorable response to oral formulations. In subsets of children who fail to respond due to intolerance, poor adherence, or inadequate intestinal absorption, parenteral iron is indicated. Despite numerous studies in adults with IDA of diverse etiologies, pediatric studies on parenteral iron use are very limited. Although mostly retrospective and small, these studies have documented the efficacy and safety profile of intravenous iron formulations. In this editorial the author comments on the most important published data and underscores the need to seriously consider parenteral iron use in children unresponsive to oral therapy.

Abstract
Objectives Anemia after surgery is common and is associated with adverse clinical outcomes. Understanding the incidence and risk factors for postoperative anemia is important to reduce anemia-related complications and blood transfusion. There is lack of data regarding postoperative anemia and its contributing factors in neurosurgery. This study evaluates the incidence and risk factors of postoperative anemia, and its impact on clinical outcomes. Methods This was a single centre, retrospective study of patients who underwent elective neurosurgery over seven months. Data regarding age, gender, body mass index, American Society of Anesthesiologists (ASA) physical status, diagnosis, surgery, preoperative hemoglobin, surgery duration, intraoperative blood loss and red blood cell (RBC) transfusion, dose of tranexamic acid, intraoperative fluid balance, years of surgeon's experience, postoperative hemoglobin, postoperative RBC transfusion, Glasgow Coma Scale (GCS) score at hospital discharge, and duration of postoperative intensive care unit and hospital stay were collected. Logistic regression was used to identify predictors of postoperative anemia. Results The incidence of postoperative anemia was 11.3% (116/1025). On univariate analysis; age, preoperative hemoglobin, surgery duration, gender, ASA grade, surgery type, and surgeon's experience were associated with postoperative anemia. Lower preoperative hemoglobin (p<0.001) and non-tumor surgery (p<0.001) were predictive of postoperative anemia on multivariate analysis. Postoperative anemia resulted in increased RBC transfusion (p<0.001) and lower GCS score at discharge (p=0.012). Conclusions Atleast one in ten patients undergoing elective neurosurgery develop postoperative anemia. Lower preoperative hemoglobin and non-tumor surgery predict anemia. Anemia results in increased RBC transfusion and lower discharge GCS score.

Abstract
The preoperative clinical and laboratory evaluations of the patient is an essential step to ensure the safety and success of any surgical procedure. This assessment aims to identify any underlying medical conditions and risk factors and determine suitability for surgery. With this step, the medical team can adapt the care plan to meet each patient's specific needs, increasing the chances of a successful procedure. Good clinical assessment and comprehensive laboratory testing, when integrated into a Patient Blood Management approach, are invaluable in promoting safety of care, reducing transfusion risks, improving surgical outcomes, and optimizing resource utilization. This approach not only elevates the quality of care, but is also aligned with evidence-based practice and patient-centered principles, making it an essential component of the perioperative process.

Abstract
Managing anemia before surgery is extremely important as it is a clinical condition that can significantly increase surgical risk and affect patient outcomes. Anemia is characterized by a reduction in the number of red blood cells or hemoglobin levels leading to a lower oxygen-carrying capacity of the blood. Proper treatment requires a multifaceted approach to ensure patients are in the best possible condition for surgery and to minimize potential complications. The challenge is recognizing anemia early and implementing a timely intervention to correct it. Anemic patients are more susceptible to surgical complications such as increased infection rates, slower wound healing and increased risk of cardiovascular events during and after surgery. Additionally, anemia can exacerbate existing medical conditions, causing greater strain on organs and organ systems. To correct anemia and optimize patient outcomes, several essential measures must be taken with the most common being identifying and correcting iron deficiency.

Abstract
BACKGROUND Anemia is extremely common among patients admitted to pediatric intensive care. Alternative treatments to transfusions such as intravenous iron must be considered. There are no published data for a prospective intravenous (IV) iron study focused in the critically ill children. The objective is to examine the safety and efficacy of intravenous iron sucrose infusion to manage anemia in pediatric critical care. A secondary objective is to examine the effect of different dose regimens of iron sucrose (3, 5, and 7 mg/kg dose). PROCEDURE Prospective investigation of intravenous iron sucrose utilization at a tertiary pediatric intensive care unit between October 2017 and November 2022. RESULTS In all 115 patients received a total of 616 infusions of IV iron. Transferrin saturation index (TSI) was the most common altered iron deficiency biomarker (91.8%). After IV iron treatment, hemoglobin showed a significant increase within a 30-day follow-up (9.2 vs. 11.6 g/dL, p < .001). There was also a significant improvement in TSI and serum iron (p < .001). Iron deficit replacement was higher in the 7 mg/kg dose group (94%) compared to 85.9% in the 5 mg/kg regimen and 77.5% in the lower dose group (p = .008), requiring less doses and a shorter time. Very few mild adverse reactions were reported (1.3% of infusions), with no differences between groups. The most frequent adverse effect was gastrointestinal in three cases. There were no anaphylaxis-like or other serious/life-threatening adverse effects. CONCLUSIONS This is the first study to evaluate intravenous iron therapy in pediatric critical care, providing preliminary evidence of safety and efficacy of IV iron sucrose. The 7 mg/kg dose regimen showed higher iron deficit replacement in a shorter time, which could be beneficial in critically ill children.

Abstract
With the aging of the population, an increasing number of elderly patients are opting for artificial joint replacement, leading to the exploration of various rapid rehabilitation programs in the perioperative period. In this study, we aimed to investigate the effectiveness of combining recombinant human erythropoietin and iron sucrose in altering the range and trend of postoperative hemoglobin in patients undergoing arthroplasty. Specifically, we will examine whether this combination can effectively alter the rise and fall of postoperative haemoglobin, identify the inflection point of haemoglobin change or recovery after arthroplasty, and assess the effect of treatment on serum iron in postoperative blood. We conducted a retrospective study of 138 patients who underwent unilateral total joint arthroplasty by the same surgeon in the same hospital before July 2022. The results of this study may provide valuable insights for the development of effective rehabilitation programs for patients undergoing arthroplasty.

Abstract
Iron deficiency anemia (IDA) is a major health burden among women in Asia. Key issues in IDA management in Asia are under-diagnosis and under-treatment. The lack of Asia-specific guidelines, and suboptimal utilization of treatment compounds the management of IDA. To address these gaps, a panel of 12 experts in obstetrics, gynecology, and hematology from six regions in Asia convened to review current practices and clinical evidence and provide practical guidance on IDA diagnosis and management in Asian women. The Delphi approach was used to obtain objective opinions and attain consensus on statements pertaining to awareness, diagnosis, and management of IDA. In total, 79 statements attained consensus and are summarized to provide guidance on raising awareness of IDA and approaches for improved diagnosis and treatment of IDA among women in various settings: pregnancy, postpartum, heavy menstrual bleeding, gynecologic cancers, and perioperative care. This clinician-led consensus integrates appropriate recommendations based on clinical evidence and best practices and is intended to guide decision making in the management of iron deficiency/IDA in women. The expert panel raises a call for timely diagnosis and utilization of appropriate treatment, including use of high-dose intravenous iron, stringent blood management, and interdisciplinary collaboration, for optimization of IDA management among women in Asia.

Effect of hemoglobin and oxygen saturation on adverse outcomes in children with tetralogy of fallot: a retrospective observational study. BMC Anesthesiol 2023; 23:346. [PMID: 37848817 PMCID: PMC10580598 DOI: 10.1186/s12871-023-02290-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 09/21/2023] [Indexed: 10/19/2023] Open
Abstract
BACKGROUND Tetralogy of Fallot (TOF) is a common cyanotic congenital heart malformation that carries a high risk of right-to-left shunting. Anemia is characterized by decreased hemoglobin (Hb) levels that can affect tissue oxygen delivery and impact postoperative recovery in patients. Chronic hypoxia caused by right-to-left shunting of TOF could lead to compensatory increases in Hb to maintain systemic oxygen balance. This study aims to investigate whether preoperative Hb and blood oxygen saturation (SpO2) can predict adverse outcomes in children undergoing corrective surgery for TOF. METHODS This retrospective study included patients under 18 years of age who underwent corrective surgery for TOF at Fuwai Hospital between January 2016 and December 2018. Adverse outcomes, including in-hospital death, extracorporeal membrane oxygenation implantation, ICU stay > 30 days, and severe complications, were considered as the primary outcome. Univariable and multivariable logistic analyses were performed to identify independent risk factors for adverse outcomes. Propensity score-matched (PSM) analysis was also conducted to minimize the confounding factors. RESULTS A total of 596 children were included in the study, of which 64 (10.7%) experienced adverse outcomes. Hb*SpO2 < aaHb was identified as an independent risk factor for adverse outcomes (OR = 2.241, 95% CI = 1.276-3.934, P = 0.005) after univariable and multivariable logistic analyses. PSM analysis further confirmed the association between Hb*SpO2 < aaHb and adverse outcomes. Patients with Hb*SpO2 < aaHb had a significantly higher incidence of postoperative adverse outcomes, longer time of mechanical ventilation, and hospital stay, as well as higher in-hospital costs. CONCLUSIONS Hb*SpO2 < aaHb is significantly associated with adverse outcomes in children undergoing corrective surgery for TOF. Clinicians can use this parameter to early identify high-risk children and optimize their postoperative management.

Abstract
BACKGROUND Iron deficiency (ID), a known complication after metabolic surgery, is common among preoperative patients in the presence of inflammation. Evidence is now accumulating that preoperative ID may adversely affect perioperative outcomes. OBJECTIVES To investigate the relationship between preoperative iron status and the risk of postoperative severe anemia. In addition, this study investigates the relationship between preoperative iron status and length of surgical stay SETTING: A large regional tertiary health system. METHODS Among patients who underwent metabolic surgery between 2004 and 2020, 5171 patients had a full iron nutritional assessment prior to surgery. Study patients were divided into multiple smaller groups (10 female groups and 7 male groups) on the basis of levels of serum ferritin and Transferrin Saturation (T Sat) < or ≥20%. Study patients were followed after surgery and the time to the development of severe anemia (hemoglobin < 8 gm/dL) was recorded. Hospital length of stay (LOS) was analyzed in relation to preoperative iron status. RESULTS Lower ferritin levels were associated with older age in males (P = .0001) and younger age in females (P < .0001). For males, after adjustment for age, body mass index (BMI), and year of surgery, surgical LOS was prolonged in those with T Sat <20% (P = .0041). For females the time until the development of severe anemia was associated with baseline iron status (P < .0001). CONCLUSIONS Male preoperative patients for metabolic surgery with T Sat <20% are at risk for increased surgical LOS. Females with low ferritin levels consistent with ID are at increased risk for the development of postoperative severe anemia.

Abstract
BACKGROUND Postoperative anemia is a risk factor for adverse surgical outcomes. Our study aimed to assess the role of intravenous iron and erythropoietin therapy for the rapid correction of anemia following orthopedic surgery. METHODS Patients undergoing elective orthopedic surgery were prospectively enrolled and randomly divided into three groups: Control (placebo), Group 1 (IV iron monotherapy), and Group 2 [combined IV iron and recombinant human erythropoietin (rHuEPO) therapy]. Blood tests were performed preoperative (baseline) and on postoperative days (PODs) 1, 3, and 7. RESULTS All groups demonstrated significantly lower hemoglobin (Hb) concentrations compared to baseline, with no significant inter-group differences in postoperative Hb concentrations (p > 0.05). Serum erythropoietin, ferritin, and vitamin B12 levels, and reticulocyte count increased beyond normal ranges in all groups. Significantly lower serum iron levels were observed postoperatively in all groups (p < 0.05). No significant inter-group differences in hepcidin level were observed (p > 0.05). CONCLUSION Postoperative treatment with combined intravenous iron and rHuEPO was ineffective in correcting postoperative anemia among orthopedic surgery patients, besides achieving higher reticulocyte counts in the first week of surgery. No improvement in mobilization of storage iron was achieved with rHuEPO. We further suggest against vitamin B12 administration during the early postoperative period.

Abstract
Iron deficiency (ID) and iron deficiency anemia (IDA) are highly prevalent worldwide. Oral iron salts, especially ferrous sulfate, are commonly used for the treatment of iron deficiency (ID). However, its use is associated with gastrointestinal side effects, thus compromising treatment compliance. Intravenous iron administration is a more costly and logistically complex alternative and is not risk-free, as infusion and hypersensitivity reactions may occur. Sucrosomial® iron is an oral formulation consisting of ferric pyrophosphate conveyed by a phospholipid and sucrester matrix (sucrosome®). Intestinal Sucrosomial® iron absorption is mediated by enterocytes and M cells, through the paracellular and transcellular routes, and occurs mostly as intact particles. These pharmacokinetic properties of Sucrosomial® iron result in higher iron intestinal absorption and excellent gastrointestinal tolerance compared to oral iron salts. The evidence derived from clinical studies supports the use of Sucrosomial® iron as a valid first option for the treatment of ID and IDA, especially for subjects who are intolerant or refractory to conventional iron salts. Newer evidence also demonstrates the effectiveness of Sucrosomial® iron, with a lower cost and fewer side effects, in certain conditions usually treated with IV iron in current clinical practice.

Abstract
BACKGROUND Preoperative anemia is common and associated with adverse postoperative outcomes. Assessment of hemoglobin concentrations may facilitate optimization prior to surgery. However, phlebotomy-based hemoglobin measurement may contribute to patient discomfort and iatrogenic blood loss, which makes non-invasive hemoglobin estimation attractive in this setting. STUDY DESIGN AND METHODS This is a prospective study of adult patients presenting for preoperative evaluation before elective surgery at a tertiary care medical center. The Masimo Pronto Pulse CO-Oximeter was utilized to estimate blood hemoglobin concentrations (SpHb), which were then compared with hemoglobin concentrations obtained via complete blood count. Receiver operating curves were used to identify SpHb values maximizing specificity for anemia detection while meeting a minimum sensitivity of 80%. RESULTS A total of 122 patients were recruited with a median (interquartile range) age of 66 (58, 72) years. SpHb measurements were obtained in 112 patients (92%). SpHb generally overestimated hemoglobin with a mean (± 1.96 × standard deviation) difference of 0.8 (-2.2, 3.9) g/dL. Preoperative anemia, defined by hemoglobin <12.0 g/dL in accordance with institutional protocol, was present in 22 patients (20%). The optimal SpHb cut-point to identify anemia was 13.5 g/dL: sensitivity 86%, specificity 81%, negative predictive value 96%, and positive predictive value 53%. Utilizing this cut-point, 60% (73/122) of patients could have avoided phlebotomy-based hemoglobin assessment, while an anemia diagnosis would have been missed in <3% (3/122). CONCLUSION The use of SpHb devices for anemia screening in surgical patients is feasible with the potential to reliably rule-out anemia despite limited accuracy.

Abstract
PURPOSE OF REVIEW The purpose of this review is to evaluate the current recommendations for management of perioperative anaemia in patients undergoing thoracic surgery, present the impact of anaemia on outcomes in this patient population and suggest an algorithm for evaluating and treating anaemia preoperatively. RECENT FINDINGS Anaemia is a common medical issue noted preoperatively in patients presenting for thoracic surgery and carries significant morbidity. Preoperative anaemia increases the likelihood of receiving a perioperative transfusion, which represents a significant risk factor for morbidity and reduced disease-free survival in lung cancer patients presenting for thoracic surgery. It is also associated with longer hospital lengths of stay and increased risk for reoperation following lung transplantation. An algorithm-based approach to management of anaemia is beneficial and treatment with iron has been shown to reduce transfusions. SUMMARY Patients undergoing thoracic surgery have a high incidence of preoperative anaemia that increases the risk of transfusion and postoperative morbidity. Preoperative evaluation and tailored treatment based on the underlying cause of anaemia reduces the incidence of anaemia prior to surgery and decreases transfusion rates.

Abstract
PURPOSE Preoperative anemia is associated with adverse outcomes after cardiac and noncardiac surgeries, but outcomes after an endovascular peripheral vascular intervention (PVI) are not well established. We aimed to assess the association of preoperative anemia with 30 day death, hospital length of stay (LOS), and overall (long term) survival in patients undergoing an endovascular PVI for peripheral artery disease. MATERIALS AND METHODS In this retrospective, cohort study in the United States and Canada, we queried the national Vascular Quality Initiative database for all endovascular PVIs performed between 2010 and 2019, and outcomes were correlated with patients' hemoglobin (Hb) levels. Anemia was classified as mild (Hb=10-13 g/dL for men and 10-12 g/dL for women), moderate (Hb=8-9.9 g/dL), and severe (Hb<8 g/dL). RESULTS A total of 79 707 adult patients who met study criteria underwent endovascular PVI. The mean age was 68 years, and 59% of patients were male. Anemia was documented in 38 543 patients (48%) and was mild in 27 435 (71%), moderate in 9783 (25%), and severe in 1325 (4%). The median follow-up duration was 4 years (range, 1.25-5.78 years). On univariate analysis, 30 day mortality, total LOS, and overall survival were significantly associated with the level of preoperative anemia. These associations persisted in the multivariate models. Kaplan-Meier survival analysis demonstrated an association of death with degree of anemia (p<0.001). CONCLUSION The presence and degree of preoperative anemia were independently associated with increased 30 day mortality and LOS and decreased overall survival for patients with peripheral artery disease who had undergone endovascular PVI. CLINICAL IMPACT The findings from this study have many implications for how to approach vascular surgery in patients with variable hemoglobin levels. Our findings will strengthen our ability to conduct accurate preoperative risk stratification for patients undergoing peripheral vascular interventions. This may also mitigate healthcare expenditures if findings are applied in a way that can lower patient length of postoperative stay while also maintaining quality of care and patient safety. Our results will also serve as guidance for clinical trials, and future prospective trials should evaluate the effect of preoperative optimization of hemoglobin as a potentially modifiable risk factor for outcomes.

Abstract
Background Recent studies show an increase in the prevalence of iron deficiency anemia (IDA) worldwide and a concomitant rise in the number of revision total knee arthroplasty (RTKA). The literature evaluating the association between IDA and perioperative outcomes following RTKA are limited. Therefore, the purpose of this study was to determine whether IDA patients undergoing RTKA have higher rates of (1) in-hospital lengths of stay (LOS), (2) complications; and (3) costs. Methods Using International Classification of Disease, Ninth Revision (ICD-9) and Current Procedural Terminology (CPT), a retrospective query was performed from January 1st, 2005 to March 31st, 2014. The inclusion criteria consisted of those patients who have IDA undergoing RTKA. Study group patients were 1:5 ratio matched to a comparison cohort by age, sex, and various comorbidities: coronary artery disease, chronic obstructive pulmonary disease, diabetes mellitus, hyperlipidemia, hypertension, obesity, and tobacco use, yielding a total of 106,534 patients within the study (n = 17,784) and control (n = 88,750) cohorts. Outcomes assessed included: in-hospital LOS, costs of care, and medical complications. Multivariate Logistic regression analyses were used to calculate the odds-ratios (OR) and respective 95% confidence intervals (95%CI). Welch’s t-tests were used to compare in-hospital LOS and costs of care. Following Bonferroni-correction, a P-value less than 0.001 was considered statistically significant. Results IDA patients undergoing RTKA were found to have significantly higher in-hospital LOS (4-days vs. 3-days, P < 0.0001). Additionally, IDA patients were found to have significantly higher odds (OR) of medical complications (OR: 5.29, P < 0.0001) such as: pneumonia (OR: 6.86, P < 0.0001), respiratory failures (OR: 5.95, P < 0.0001), myocardial infarctions (OR: 4.31, P < 0.0001) and other complications. Furthermore, IDA patients incurred significantly higher day of surgery ($16,976.01 vs. $14,515.81, P < 0.0001) and 90-day costs ($22,548.71 vs. $16,819.15, P < 0.0001). Conclusion The study demonstrated IDA patients undergoing RTKA have higher rates of in-hospital LOS, costs of care, and medical complications. Orthopedic surgeons and other healthcare professionals can use this information to adequately educate these patients of the potential complications following their procedure.

Clinical, economical and safety impact of ferric carboxymaltose use in Patient Blood Management programme in Portuguese National Health Service hospitals. Sci Rep 2022; 12:19335. [PMID: 36369296 PMCID: PMC9652329 DOI: 10.1038/s41598-022-21929-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 10/06/2022] [Indexed: 11/13/2022] Open
Abstract
Ferric carboxymaltose (FCM) can be used in Patient Blood Management (PBM) to promote the optimization of preoperative haemoglobin (Hb), which aims to minimise the use of allogeneic blood components and improve clinical outcomes, with better cost-effectiveness. This was an observational study conducted in a retrospective and multicentre cohort with adults from elective orthopaedic, cardiac and colorectal surgeries, treated according to local standards of PBM with allogeneic blood product transfusions (ABTs) on demand and with FCM to correct iron deficiency with or without anaemia. In this work, only the first pillar of the PBM model issue by Directorate-General for Health (DGS) was evaluated, which involves optimising Hb in the preoperative period with iron treatment if it's necessary/indicated. Before the implementation of PBM in Portugal, most patients did not undergo preoperative laboratory evaluation with blood count and iron kinetics. Therefore, the existence of Iron Deficiency Anaemia (IDA) or Iron Deficiency (ID) without anaemia was not early detected, and there was no possibility of treating these patients with iron in order to optimise their Hb and/or iron stores. Those patients ended up being treated with ABTs on demand. A total of 405 patients from seven hospitals were included; 108 (26.7%) underwent FCM preoperatively and 197 (48.6%) were transfused with ABTs on demand. In the FCM preoperative cohort, there was an increase in patients with normal preoperative Hb, from 14.4 to 45.7%, before and after FCM, respectively, a decrease from 31.7 to 9.6% in moderate anaemia and no cases of severe anaemia after FCM administration, while 7.7% of patients were severely anaemic before FCM treatment. There were significant differences (p < 0.001) before and after correction of preoperative anaemia and/or iron deficiency with FCM in Hb, serum ferritin and transferrin saturation rate (TS). In the ABT group, there were significant differences between pre- and postoperative Hb levels (p < 0.001). Hb values tended to decrease, with 44.1% of patients moving from mild anaemia before transfusion to moderate anaemia in the postoperative period. Concerning the length of hospital stay, the group administered with ABTs had a longer hospital stay (p < 0.001). Regarding the clinical outcomes of nosocomial infection and mortality, there was no evidence that the rate of infection or mortality differed in each group (p = 0.075 and p = 0.243, respectively). However, there were fewer nosocomial infections in the FCM group (11.9% versus 21.2%) and mortality was higher in the transfusion group (21.2% versus 4.2%). Economic analysis showed that FCM could reduce allogenic blood products consumption and the associated costs. The economic impact of using FCM was around 19%. The preoperative Hb value improved when FMC was used. Patients who received ABTs appeared to have a longer hospital stay. The FCM group reported fewer infections during hospitalisation. The economic results showed savings of around €1000 for each patient with FCM administration. The use of FCM as part of the PBM program had a positive impact on patients' outcomes and on economic results. However, it will be essential to perform studies with a larger sample to obtain more robust and specific results.

Abstract
Autoimmune thyroid disease (AITD) is the most prevalent autoimmune disease all over the world and the most frequent cause of hypothyroidism in areas of iodine sufficiency. The pathogenesis of AITD is multifactorial and depends on complex interactions between genetic and environmental factors, with epigenetics being the crucial link. Iron deficiency (ID) can reduce the activities of thyroid peroxidase and 5′-deiodinase, inhibit binding of triiodothyronine to its nuclear receptor, and cause slower utilization of T3 from the serum pool. Moreover, ID can disturb the functioning of the immune system, increasing the risk of autoimmune disorders. ID can be responsible for residual symptoms that may persist in patients with AITD, even if their thyrometabolic status has been controlled. The human lifestyle in the 21st century is inevitably associated with exposure to chemical compounds, pathogens, and stress, which implies an increased risk of autoimmune disorders and thyroid dysfunction. To summarize, in our paper we discuss how iron deficiency can impair the functions of the immune system, cause epigenetic changes in human DNA, and potentiate tissue damage by chemicals acting as thyroid disruptors.

Abstract
Colorectal cancer is one of the most common cancers in Europe and the world. Cancer treatments have side effects and cause significant deterioration of the patient’s nutritional status. Patient malnutrition may worsen the health condition and prevent the deliberate effects of the therapy. The aim of this review was to describe the available data about clinical nutrition in colorectal cancer patients. A large proportion of colorectal cancer patients suffer from malnutrition, which negatively affects the survival prognosis, quality of life, and oncological therapy. Therefore, monitoring nutritional status during the treatment is essential and can be used to arrange proper nutritional therapy to enhance patient responses, prevent side effects, and shorten recovery time. The principles of nutrition during anticancer therapy should mainly consider light and low-fat foods, the exclusion of lactose and gluten-containing foods in certain cases, or the introduction of special dietary products such as oral nutrition supplements and it should be tailored to patients’ individual needs.

Abstract
Iron deficiency (ID), with or without anemia, is commonly found worldwide and affects the health and wellbeing of pregnant and nonpregnant women. Symptoms of ID- which include fatigue, pica (ice craving), restless legs syndrome, poor concentration and work function, increased susceptibility to infection, and cardiovascular stress- can cause significant morbidity and reduced quality of life. The etiologies of iron deficiency in women are usually specific to each community. In the developing world, iron deficiency is usually associated with poor iron intake and parasitic infections, whereas in higher income regions, iron deficiency is typically the result of heavy, abnormal uterine bleeding, and pregnancy. Iron-poor diets and poor iron absorption resulting from gut disorders can also play a role. Diagnosis of iron deficiency is usually straightforward and characterized by a low ferritin level; however, the diagnosis can be challenging in women with concomitant inflammatory disorders, in which case a low percent transferrin saturation, performed after an overnight fast, can inform on the need for iron. Therapy is frequently initiated with oral iron salts; however, use of these oral regimens is commonly associated with adverse events, mostly gastrointestinal in nature, that have been shown to adversely impact compliance, continuation, and the achievement of therapeutic goals. A further impediment to the effectiveness of oral iron is its poor absorption because of comorbidity (i.e., celiac disease, gastritis, etc.), surgery (bariatric), or physiologic inhibitory mechanisms. As such, intravenous (IV) iron regimens are increasingly being used to treat ID, as such regimens have been shown to avoid the gastrointestinal adverse events commonly associated with oral regimens. Indeed, IV iron has been shown to provide adequate iron replacement in women with functional iron deficiencies as well as those with ID resulting from inflammatory disorders- patients often resistant to oral iron therapy. More recent IV iron regimens have been shown to provide iron replacement in a safe and effective manner, being associated with more salutary adverse event profiles than earlier IV iron regimens. In fact, these iron regimens can provide a complete replacement dose in a single 15-60-min visit.

Abstract
INTRODUCTION Postoperative anemia is associated with substantial morbidity and mortality in total joint arthroplasty (TJA). Our primary objective was to determine whether perioperative iron supplementation improves postoperative hemoglobin levels in TJA. Secondary objectives were to determine the effects of perioperative iron on adverse events, quality of life, and functional measures in TJA. METHODS We conducted a systematic review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using six databases. We included English-language, randomized controlled trials investigating intraoperative or postoperative iron supplementation in elective TJA that reported postoperative hemoglobin levels in patients aged 18 years or older. Seven eligible studies were identified, among which substantial heterogeneity was noted. Bias risk was low in four studies, unclear in two studies, and high in one study. Three studies assessed oral iron supplementation, three assessed intravenous iron supplementation, and one compared oral and intravenous iron supplementation. All intravenous iron was administered intraoperatively, except in the oral versus intravenous comparison. RESULTS Postoperative oral iron supplementation had no effect on postoperative hemoglobin levels. Intraoperative and postoperative intravenous iron supplementation was associated with higher postoperative hemoglobin levels and greater increases in hemoglobin levels. Two studies reported rates of anemia and found that intraoperative and postoperative intravenous iron supplementation reduced rates of postoperative anemia at postoperative day 30. No adverse events were associated with iron supplementation. One study found that intravenous iron improved quality of life in TJA patients with severe postoperative anemia compared with those treated with oral iron. Perioperative iron had no effects on functional outcomes. DISCUSSION We found no evidence that postoperative oral iron supplementation improves hemoglobin levels, quality of life, or functional outcomes in elective TJA patients. However, intraoperative and postoperative intravenous iron supplementation may accelerate recovery of hemoglobin levels in these patients.

Abstract
Complex surgery associated with major hemorrhage presents particular risks for Jehovah's Witnesses who do not accept transfusion of blood products. Intraoperative use of two cell saver machines simultaneously can maximize the yield of salvaged blood from both the operative field and from washed surgical swabs and can potentially be life-saving.

Abstract
The aim of this work was the synthesis of hybrid materials of iron (II)-based therapeutic systems via the sol-gel method. Increasing amounts of polyethylene glycol (PEG 6, 12, 24, 50 wt%) were added to SiO2/Fe20 wt% to modulate the release kinetics of the drug from the systems. Fourier-transform infrared (FTIR) spectroscopy was used to study the interactions between different components in the hybrid materials. The release kinetics in a simulated body fluid (SBF) were investigated, and the amount of Fe2+ released was detected via ultraviolet-visible spectroscopy (UV-Vis) after reaction with ortho-phenanthroline. Furthermore, biological characterization was carried out. The bioactivity of the synthesized hybrid materials was evaluated via the formation of a layer of hydroxyapatite on the surface of samples soaked in SBF using spectroscopy. Finally, the potential antibacterial properties of seven different materials against two different bacteria—E. coli and S. aureus—were investigated.

Abstract
Purpose Studies have shown the prevalence of iron deficiency anemia (IDA) increasing worldwide, and currently the literature is limited on the impact of IDA on outcomes following revision total hip arthroplasty (RTHA). Therefore, the purpose of this study was to determine whether IDA patients undergoing RTHA have longer: 1) in-hospital lengths of stay (LOS); 2) medical complications; and 3) costs of care. Materials and Methods A retrospective query of a nationwide administrative claims database was performed. Using Boolean command operations, the study group consisted of all patients in the database undergoing RTHA with IDA; whereas, patients without IDA served as controls. To reduce the effects of confounding, study group patients were matched to controls in a 1:5 ratio by age, sex, and medical comorbidities yielding 92,948 patients with (n=15,508) and without (n=77,440) IDA undergoing revision THA. A P-value less than 0.001 was considered statistically significant. Results IDA patients were found to have significantly longer in-hospital LOS (5 days vs. 4 days, P<0.0001). Additionally, the study showed IDA patients were found to higher incidence and odds of (73.84% vs. 11.77%, OR 5.04, P<0.0001) 90-day medical complications. IDA patients also incurred high 90-day episode of care costs ($25,597.51 vs. $20,085.70, P<0.0001). Conclusion After adjusting for age, sex, and medical comorbidities this study of over 92,000 patients demonstrated IDA is associated with longer in-hospital LOS, complications, and costs of care. Future studies should compare the duration and severity of IDA on outcomes.

Reticulocyte and Erythrocyte Hemoglobin Parameters for Iron Deficiency and Anemia Diagnostics in Patient Blood Management. A Narrative Review. J Clin Med 2021; 10:jcm10184250.

Abstract
Anemia, iron deficiency and other hematinic deficiencies are a major cause of perioperative transfusion needs and are associated with increased morbidity and mortality. Anemia can be caused either by decreased production of hemoglobin or red blood cells or by increased consumption and blood loss. Decreased production can involve anything from erythropoietin or vitamin B12 insufficiency to absolute or functional lack of iron. Thus, to achieve the goal of patient blood management, anemia must be addressed by addressing its causes. The traditional parameters to diagnose anemia, despite offering elaborate options, are not ideally suited to giving a simple overview of the causes of anemia, e.g., iron status for erythropoiesis, especially during the acute phase of inflammation, acute blood loss or iron deficiency. Reticulocyte hemoglobin can thus help to uncover the cause of the anemia and to identify the main factors inhibiting erythropoiesis. Regardless of the cause of anemia, reticulocyte hemoglobin can also quickly track the success of therapy and, together with the regular full blood count it is measured alongside, help in clearing the patient for surgery.

Abstract
This article analyzes the recommendations issued by the Emilia Romagna region in July 2020 on “Organizational strategies for the safe management of intravenous iron therapy in patients in non-hospitalized settings”. The objective of these recommendations is to set up safe intravenous iron administration sites outside the hospital environment across the national territory. The document facilitates the organization of methods for intravenous iron infusion that are safe for the patient and correct from a medico-legal perspective. In addition, it opens the way for the widespread use of iron infusion in the field, providing benefits to patient quality of life. This program prevents unnecessary transfusions, reduces costs, prevents overcrowding in hospitals in the event of a pandemic, and enables patient treatment in the field, thus, saving on the use of personnel.

Abstract
Background The prevalence of anaemia in patients planned for total hip and knee arthroplasty is about 20%. Optimising pre-operative haemoglobin levels by iron supplementation has been shown to decrease transfusion rates, complications and associated morbidity. The need for universal screening with iron studies of all elective arthroplasty patients is not clearly defined at present. Methods Retrospective review of 2 sequential cohorts of patients undergoing primary hip or knee arthroplasty by a single surgeon at a single centre between January 2013 and December 2017. The first group of patients underwent pre-operative iron studies only if found to be anaemic, with a haemoglobin below 12g/dl. From January 2015, all patients irrespective of the presence of anaemia were screened with a complete iron profile before surgery. Patients with a confirmed iron deficiency were administered with intravenous iron prior to surgery. The 2 cohorts were compared with regard to blood transfusion rate post-operatively and cost efficiency for universal screening with iron studies. Results There was a net decrease in the allogenic blood transfusion rate from 4.76 to 2.92% when universal iron studies were introduced but the difference was not statistically significant. Obtaining universal pre-operative iron studies is cost neutral with the price of allogenic blood transfusion in a similar cohort. We also diagnosed 5 patients with occult malignancies. Conclusions Universal screening with pre-operative iron studies and iron infusion in elective arthroplasty patients may reduce allogenic blood requirements and is cost neutral. An additional benefit is the potential to diagnose asymptomatic malignancies. Further studies are required to show the true benefit of universal pre-operative iron screening.

Abstract
OBJECTIVES Guidelines recommend retrograde autologous priming (RAP) of the cardiopulmonary bypass circuit. However, the efficacy and safety of RAP is not well-established. We performed a systematic review and meta-analysis to determine the effects of RAP on transfusion requirements, morbidity and mortality. METHODS We searched Cochrane Central Register of Controlled Trials, Medline, ScienceDirect, Cumulative Index to Nursing and Allied Health Literature and Embase for randomized controlled trials (RCTs) and observational studies comparing RAP to no-RAP. We performed title and abstract review, full-text screening, data extraction and risk of bias assessment independently and in duplicate. We pooled data using a random effects model. RESULTS Twelve RCTs (n = 1206) and 17 observational studies (n = 3565) were included. Fewer patients required blood transfusions with RAP [RCTs; risk ratio 0.58 [95% confidence interval (CI): 0.51, 0.65], P < 0.001, and observational studies; risk ratio 0.65 [95% CI: 0.53, 0.80], P < 0.001]. The number of units transfused per patient was also lower among patients who underwent RAP (RCTs; mean difference -0.38 unit [95% CI: -0.72, -0.04], P = 0.03, and observational studies; mean difference -1.03 unit [95% CI: -1.76, -0.29], P < 0.006). CONCLUSIONS This meta-analysis supports the use of RAP as a blood conservation strategy since its use during cardiopulmonary bypass appears to reduce transfusion requirements.

Abstract
Bleeding is a consequence of insufficient hemostasis and excessive bleeding at a surgical site is associated with an increased risk of post-operative infection, transfusion and re-operation, in addition to increased hospital length of stay and costs. Surgeons employ a range of methods to achieve hemostasis, including topical hemostatic agents of differing composition and properties. Hemostatic powders are a sub-group of topical hemostats, which can be used in helping as adjuncts to manage troublesome bleeding in a variety of situations. As this technology is relatively new and potentially not well known by the broad surgical community, no specific guidelines or recommendations for the optimal use of hemostatic powders in surgery currently exist. A steering group throughout Europe of multidisciplinary surgeons, expert in hemostasis and hemostatics, identified from literature and from personal experience, five key topics. When to use hemostatic powder, the evidence for use, benefits of use, safety remarks and considerations in various surgical specialties. Thirty-seven statements were subsequently drawn from these five key topics. An online survey was sent to 128 high-volume surgeons working in breast surgery, gynaecological and obstetric surgery, general and emergency surgery, thoracic surgery and urological surgery in Europe to assess agreement (consensus) with these statements. Consensus was defined as high if ≥ 75% and very high if ≥ 90% of respondents agreed with a statement. A total of 79 responses were received and consensus among the surgical experts was very high in 27 (73%) statements, high in 8 (22%) statements and was not achieved in 2 (5%) statements. Based on the consensus scores, the steering group produced 16 key recommendations which they considered could improve patient outcomes by reducing post-operative bleeding and its associated complications using hemostatic powder.

Abstract
PURPOSE OF REVIEW In the past years, patient blood management (PBM) has evolved to improve patient's care and safety. Anemia is one of the most common medical diseases in the world and is an independent risk factor for morbidity and mortality. Iron deficiency is the main cause for anemia and constitutes a potentially preventable condition with a great impact on surgical outcome. However, preoperative anemia management is not yet established in most hospitals. Changing workflows and re-thinking is challenging. Numerous published studies confirmed the positive effect of preoperative anemia diagnosis and treatment recently. RECENT FINDINGS Iron supplementation in iron-deficient anemic (IDA) patients reduce the need for allogenic blood transfusion thereby improving perioperative outcome. SUMMARY Since the introduction of PBM programs, important movements towards early detection and therapy of preoperative anemia have been observed. However, preoperative anemia management is not implemented on a large scale as many healthcare professionals are not aware of the most recent findings in the field. Preoperative anemia management, particularly iron supplementation in IDA patients, has proven to be highly effective and has a tremendous effect on patient safety and outcome.

Abstract
The present article illustrates the green synthesis of novel carbon quantum dots (CQDs) from biomass viz. Tagetes erecta (TE), and subsequently fabrication of a metal ion probe for the sensing of Fe3+ in real samples. TE-derived CQDs (TE-CQDs) have been synthesized by a facile, eco-friendly, bottom-up hydrothermal approach using TE as a carbon source. The successful synthesis and proper phase formation of the envisaged material has been confirmed by various characterization techniques (Raman, XRD, XPS, TEM, and EDS). Notably, the green synthesized TE-CQDs show biocompatibility, good solubility in aqueous media, and non-toxicity. The as-synthesized TE-CQDs show an intense photoluminescence peak at 425 nm and exhibit excitation dependent photoluminescence behavior. The proposed TE-CQD-based probe offers a remarkable fluorescence (FL) quenching for Fe3+ with high selectivity (Kq ∼ 10.022 × 1013 M−1 s−1) and a sensitive/rapid response in a linear concentration range 0–90 μM (regression coefficient R2 ∼ 0.99) for the detection of Fe3+. The limit of detection (LOD) of the probe for Fe3+ has been found as 0.37 μM in the standard solution. It has further been applied for the detection of Fe3+ in real samples (human blood serum) and displays good performance with LOD ∼ 0.36 μM. The proposed TE-CQD-based ion sensing probe has potential prospects to be used effectively in biological studies and clinical diagnosis. TE-CQDs synthesized via the hydrothermal method for the detection of Fe3+ in HBS.![]()

Preoperative anemia and complications after surgery for pelvic organ prolapse: an analysis of the national surgical quality improvement program database. Int Urogynecol J 2021; 33:1827-1831. [PMID: 33893824 DOI: 10.1007/s00192-021-04800-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 04/09/2021] [Indexed: 10/21/2022]
Abstract
INTRODUCTION AND HYPOTHESIS Preoperative anemia is a well-established risk factor for adverse perioperative outcomes in major surgery, but studies exploring complications after pelvic reconstructive surgery are limited. The objective of this study is to examine the impact of preoperative anemia on 30-day adverse outcomes in patients undergoing pelvic organ prolapse surgery. METHODS A retrospective cohort of women undergoing pelvic organ prolapse surgery was captured from the National Surgery Quality Improvement Program database (2014-2019). The primary outcome was a composite of postoperative medical complications such as pulmonary embolism, acute renal failure, stroke, myocardial infarction, cardiac arrest, deep vein thrombosis, and sepsis. Secondary outcomes included surgical site infection, bleeding requiring blood transfusion, readmission within 7 days of surgery, and return to the operating room within 30 days. Multivariate logistic regression was used to adjust for important pre-specified potential confounders. RESULTS A total of 50,848 women were included in the analysis and 9.9% (4,579) met the criteria for anemia (hematocrit <36%). Potentially serious medical complications were rare, occurring in only 348 women (0.7%), and were more common among anemic patients (1.1% vs 0.6%, p < 0.001). On multivariate analysis, preoperative anemia was associated with higher odds of both potentially serious medical complications (OR 1.38, 95% CI 1.01-1.88) and returning to the operating room (OR 1.55, 95% CI 1.23-1.94). Anemic patients had a four-fold increase in the odds of requiring a blood transfusion (OR 4.47, 95% CI 3.60-5.56). CONCLUSIONS Preoperative anemia is associated with an increased risk of adverse postoperative outcomes in women having surgery for pelvic organ prolapse.

Intravenous iron supplementation after liver surgery: Impact on anemia, iron, and hepcidin levels-a randomized controlled trial. Surgery 2021; 170:813-821. [PMID: 33888314 DOI: 10.1016/j.surg.2021.03.020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2020] [Revised: 02/11/2021] [Accepted: 03/06/2021] [Indexed: 01/28/2023]
Abstract
BACKGROUND Anemia is a recognized risk factor for perioperative related morbidity and mortality and is frequently reported in liver surgeries with an estimated incidence of 32%. We aim to assess the impact of intravenous iron administration in the immediate postoperative period on anemia and iron status as well as to determine the kinetics of hepcidin after liver surgery. METHODS The HepciFer trial, a randomized controlled trial, included 50 patients undergoing liver surgery. In accordance with the randomization process, patients received either ferric carboxymaltose (15 mg/kg, maximum 1 g) or placebo 4 hours after surgery. RESULTS The mean hemoglobin level, 7 days after surgery, did not differ significantly between the intervention and control group (11.1 ± 1.8 g/dL and 10.4 ± 1.6 g/dL, respectively) with a mean difference of +0.7 g/dL ([95% confidence interval, -0.3 to +1.7], P = .173). Within patients receiving intravenous iron supplementation, none presented biological signs of functional iron deficiency. Hepcidin levels remained significantly higher during the observation period in the intervention group. Inflammatory biomarkers, red blood cells transfusion rate and hospital duration of stay were similar between groups. CONCLUSION Intravenous ferric carboxymaltose administration did not result in a significant increase of hemoglobin levels 7 days after surgery. However, this study suggests that intravenous iron supplementation in the immediate postoperative settings prevents functional iron deficiency. Intravenous iron supplementation overcame the hepcidin-mediated blockade of iron absorption and should be considered as the preferred route of administration in the postoperative period.

Transfus Apher Sci 2021; 60:103139.

Abstract
BACKGROUND Iron deficiency anaemia is a public health problem. In case oral iron treatment is ineffective, poorly tolerated or contraindicated, the intravenous route becomes the first choice. The aim of the study was to evaluate the shift between ferrous gluconate (FG) and ferric carboxymaltose (FCM) usage at our hospitals over the years. We also performed a cost comparison between pre and post-FCM availability periods, taking into account the acquisition costs of both intravenous iron and red blood cell units (PRBC). STUDY DESIGN AND METHODS The amount and costs of FG and FCM released by hospital Pharmacy Services from 2010 to 2019 were analysed, along with the number of transfused PRBC units in the same timeframe. RESULTS Overall, the proportion of FCM usage rose from 8.6 % in 2014 to 71.9 % in 2019, as percentage of total intravenous iron released. After exclusion of haemodialysis, where FG is still widely used, the FCM use in the last four years raised from 12.9% to 92.5%. Despite the higher FCM cost, the mean yearly expenditure for intravenous iron plus PRBC units did not differ between pre- and post-FCM eras (2010-2013, € 2,396,876 € versus 2014-2019, € 2,307,875 - p = 0.234), as a result of a net decrease of PRBC usage, namely from 15,083 to 12,654 (-16.1 %), respectively. DISCUSSION Intravenous iron has a major role in treating iron deficiency anaemia in several settings. Third generation compounds are paving the way to more updated and safer treatments.

Abstract
Anemia is a common finding in the perioperative setting with significant untoward consequences including worsening of outcomes and diminished quality of life as well as increased risk of allogeneic blood transfusions. Here, we present 3 cases that illustrate how anemia can be perioperatively managed in patients undergoing cardiac, orthopedic, and oncology surgeries. Timely detection of anemia prior to high-blood loss surgeries can allow clinicians to manage it and optimize hemoglobin level, making patients better prepared for the surgery. Treatment of anemia should be guided by the etiology and may include erythropoietic agents, folic acid, B12, and iron preparations. Other blood management strategies geared toward reducing surgical blood loss such as autologous transfusion techniques and agents to optimize hemostasis are used during surgery and in the immediate postoperative period. Patients should be closely monitored following surgery for signs of ongoing bleeding in need of control. Finally, screening for and management of anemia should continue in the postoperative and postdischarge period, as persistence and recurrence of anemia can further undermine patient's outcomes.

Abstract
Anemia, characterized by a decrease of the hemoglobin level in the blood and a reduction in carrying capacity of oxygen, is a major public health problem which affects people of all ages. The methods used to treat anemia are blood transfusion and oral administration of iron-based supplements, but these treatments are associated with a number of side effects, such as nausea, vomiting, constipation, and stomach pain, which limit its long-term use. In addition, oral iron supplements are poorly absorbed in the intestinal tract, due to overexpression of hepcidin, a peptide hormone that plays a central role in iron homeostasis. In this review, we conducted an analysis of the literature on biologically active compounds and plant extracts used in the treatment of various types of anemia. The purpose of this review is to provide up-to-date information on the use of these compounds and plant extracts, in order to explore their therapeutic potential. The advantage of using them is that they are available from natural resources and can be used as main, alternative, or adjuvant therapies in many diseases, such as various types of anemia.

Abstract
BACKGROUND AND AIM OF THE STUDY: Iron deficiency (ID), a common malnutrition, has been linked to impaired prognosis in patients with congestive heart failure. It remains unclear whether ID also affects the outcome after elective cardiac surgery. METHODS A total of 378 consecutive patients undergoing either coronary artery bypass grafting (CABG) or surgical aortic valve replacement (SAVR) were prospectively enrolled, and blood samples were taken before surgery for analysis of iron metabolism. Incidence of major adverse cardiovascular and cerebrovascular events (MACCE) was defined as the primary endpoint of the study. RESULTS ID (ferritin < 100 ng/ml or ferritin = 100-299 ng/ml and transferrin saturation < 20%) was common in cardiac surgery patients (ID, n = 265, 70%) and related to significant decreased preoperative hemoglobin values (ID: 13.6 ± 1.6 g/dl, Non-ID: 14.3 ± 1.5 g/dl, p < 0.01). We did not observe any differences in the postoperative outcome of the two groups. The incidence of MACCE was 4.9% in patients with ID and 8.8% in Non-ID (p = 0.16). In-hospital mortality (ID: 1.9%, Non-ID: 4.4%, p = 0.17) and stroke (ID: 1.1%, Non-ID: 1.8%, p = 0.64) were also not altered by ID. In addition, intensive care unit and hospital stay, perioperative blood transfusions as well as perioperative morbidities, such as acute kidney injury, low cardiac output syndrome, major bleeding complication, and sternal wound infections were comparable in patients with and without ID. CONCLUSIONS The majority of patients undergoing elective CABG or SAVR suffer from ID; however, we found no significant differences in regard to MACCE and postoperative morbidity between ID and non-ID patients.

Abstract
BACKGROUND Over the last decade, preoperative anemia has become recognized as a clinical condition in need of management. Although the etiology of preoperative anemia can be multifactorial, two-thirds of anemic elective surgical patients have iron deficiency anemia. At the same time, one-third of non-anemic elective surgical patients are also iron deficient. METHODS Modified-RAND Delphi methodology was employed to identify areas of consensus among an expert panel regarding the management of iron deficiency in patients undergoing cardiac surgery. A list of statements was sent to panel members to respond to using a five-point Likert Scale. All panel members subsequently attended a face-to-face meeting. The initial survey was presented and discussed, and panel members responded to each statement on the Likert scale again. Based on the second survey, the panel came to a consensus on recommendations. RESULTS The panel recommended all patients undergoing cardiac surgery be evaluated for iron deficiency, whether or not anemia is present. Evaluation should include iron studies and reticulocyte hemoglobin content. If iron deficiency is present, with or without anemia, patients should receive parenteral iron. Erythropoietin stimulating agents may be appropriate for some patients. CONCLUSIONS Consensus of an expert panel resulted in a standardized approach to diagnosing and managing iron deficiency in patients undergoing cardiac surgery.

Abstract
BACKGROUND Preoperative anemia (POA) in elective surgery is associated with worse outcome. In this retrospective study, in elective hip and knee arthroplasties, the prevalence of POA and its associations with outcome were analyzed, followed by a model estimating the budget impact of screening and treatment of POA. METHODS All elective hip/knee arthroplasties performed during the period 2016-2018 were included. Patients with normal hemoglobin and patients with POA (hemoglobin < 13.0 g/dL in men and <12.0 g/dL in women) were compared. Outcome measures were allogeneic blood transfusion (ABT), length of stay (LOS), complications, mortality, and costs. The budget impact of screening for POA and treatment with intravenous iron when relevant was modeled based on the results of the costs related to POA. RESULTS In 881 procedures, the prevalence of POA was 21.5%. POA independently predicted increased risks of ABT (odds ratio [OR]adj, 9.5 [confidence interval-CI, 6.4-13.9]), prolonged LOS (ORadj, 2.8 [CI, 1.8-4.2]), and was associated with increased complications (ORadj, 1.9 [CI, 0.7-4.9]) and mortality (ORadj, 3.2 [CI, 0.8-13.5]). POA resulted in increased costs per patient (P < .001). The budget impact model showed a cost reduction of 254 euros per patient based on the assumption that patients screened and treated for iron-deficient anemia would have the same outcome as non-POA. CONCLUSION The prevalence of POA in elective orthopedic surgery in Sweden is at the same level as previously reported by others. Screening and treatment of POA would reduce costs based on less ABT and decreased LOS and may reduce complications in elective major orthopedic surgery.

Abstract
Iron deficiency is a major problem in worldwide populations, being more alarming in surgical patients. In the presence of absolute iron deficiency (depletion of body iron), functional iron deficiency (during intense bone marrow stimulation by endogenous or exogenous factors), or iron sequestration (acute or chronic inflammatory conditions), iron-restricted erythropoiesis can develop. This systemic review was conducted to draw attention to the delicate problem of perioperative anemia, and to provide solutions to optimize the management of anemic surgical patients. Systemic reviews and meta-analyses, clinical studies and trials, case reports and international guidelines were studied, from a database of 50 articles. Bone marrow biopsy, serum ferritin levels, transferrin saturation, the mean corpuscular volume, and mean corpuscular hemoglobin concentration were used in the diagnosis of iron deficiency. There are various intravenous iron formulations, with different pharmacological profiles used for restoring iron. In surgical patients, anemia is an independent risk factor for morbidity and mortality. Therefore, anemia correction should be rapid, with parenteral iron formulations—the oral ones—being inefficient. Various studies showed the safety and efficacy of parenteral iron formulations in correcting hemoglobin levels and decreasing the blood transfusion rate, the overall mortality, the postoperative infections incidence, hospitalization days, and the general costs.

Abstract
Anemia is the most common hematological disease, and is defined by the World Health Organization as a condition in which the number of red blood cells and consequently oxygen-carrying capacity is insufficient to meet the physiological needs of the body. Anemia can occur throughout the perioperative period and has important clinical consequences. Preoperative anemia is usually regarded as no more than a surrogate marker of a patient's physical status, and it is not always adequately addressed before surgery. Postoperative anemia is a common event and occurs in 80-90% of patients who have undergone major surgery. This manuscript discusses the detection and management of preoperative anemia, the three pillars of patient blood management, perioperative anemia management, and risk stratification for anemia in the surgical setting.

Effect of the application of the "Patient blood management" programme on the approach to elective hip and knee arthroplasties. Med Clin (Barc) 2020; 155:425-433. [PMID: 32475617 DOI: 10.1016/j.medcli.2020.01.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2019] [Revised: 01/16/2020] [Accepted: 01/23/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND AND OBJECTIVES The "Patient Blood Management" (PBM) programmes have demonstrated their value in the continuous improvement of care practice, due to continuous systematic reviewing of results and their dynamic and multidisciplinary updating in accordance with new clinical evidence. Our goal is to demonstrate the effectiveness of simple protocols, applicable in second level hospitals. PATIENTS AND METHODS 702 patients undergoing scheduled arthroplasty from 2011 to 2018 were retrospectively analysed. During this period, the evolution of transfusion rates and anaemia and bleeding management were recorded in the patients' computerised clinical histories. RESULTS Stages and transfusion rates were: Year 2011-2012, "Universal self-donation programme": 62.4%; year 2013, "Optimization of preoperative haemoglobin and universal self-donation withdrawal", 22.5%; year 2015, "Stopping the use of cell-savers and drains", 13.2%; and year 2017, "Introduction of routine tranexamic acid", 3.6%. A significant reduction in the transfusion rate and volume (P<.001) and the average hospital stay (8 to 6 days) (P<.001) was achieved. In multivariate models, transfused patients have a .5-day stay and there is a trend towards a reduction in complications, being fewer in patients receiving tranexamic acid (OR .44). CONCLUSION A simple progressive and multidisciplinary PBM programme, with continued re-evaluation, has allowed a reduction in transfusion rates and average hospital stay.

Abstract
The perioperative period poses a risk for anemia due to the high prevalence of pre-existing anemia secondary to underlying pathologies in patients who are candidates for surgery, and as a result of the increased blood loss caused by surgery. Pre-operative anemia is an independent risk factor associated with higher risk of blood transfusion and negative surgery outcomes. Anemia and iron deficiency (ID), the main causes of pre-operative anemia, can be easily diagnosed with blood testing and are readily treated before elective surgery. However, pre-surgical screening and treatment of anemia and ID are frequently overlooked. These topics were presented and discussed at the symposium entitled "Recovery after Surgery: Don't Forget to Check Iron Status Before", held at the 11th Annual Meeting of the European Urogynaecological Association (EUGA) in October 2018 in Milan. The objectives of the symposium were to stress the high prevalence and the consequences of pre-operative anemia, illustrated with three clinical cases of women undergoing surgery, and to choose the best option for iron supplementation. In conclusion, it is essential to take time to diagnose and treat iron deficiency anemia (IDA) before surgery. The first-line treatment is oral iron when surgery can be delayed and when there is no intolerance to oral treatment or inefficient uptake, as in the case of iron sequestration or absorption disorders. Among iron preparations, ferrous sulfate in a polymeric complex (FSPC) was found to be one of the treatments of choice to improve hemoglobin iron stores and quality of life in IDA patients.

Anemia of Inflammation with An Emphasis on Chronic Kidney Disease. Nutrients 2019; 11:nu11102424.

Abstract
Iron is vital for a vast variety of cellular processes and its homeostasis is strictly controlled and regulated. Nevertheless, disorders of iron metabolism are diverse and can be caused by insufficiency, overload or iron mal-distribution in tissues. Iron deficiency (ID) progresses to iron-deficiency anemia (IDA) after iron stores are depleted. Inflammation is of diverse etiology in anemia of chronic disease (ACD). It results in serum hypoferremia and tissue hyperferritinemia, which are caused by elevated serum hepcidin levels, and this underlies the onset of functional iron-deficiency anemia. Inflammation is also inhibitory to erythropoietin function and may directly increase hepcidin level, which influences iron metabolism. Consequently, immune responses orchestrate iron metabolism, aggravate iron sequestration and, ultimately, impair the processes of erythropoiesis. Hence, functional iron-deficiency anemia is a risk factor for several ailments, disorders and diseases. Therefore, therapeutic strategies depend on the symptoms, severity, comorbidities and the associated risk factors of anemia. Oral iron supplements can be employed to treat ID and mild anemia particularly, when gastrointestinal intolerance is minimal. Intravenous (IV) iron is the option in moderate and severe anemic conditions, for patients with compromised intestinal integrity, or when oral iron is refractory. Erythropoietin (EPO) is used to treat functional iron deficiency, and blood transfusion is restricted to refractory patients or in life-threatening emergency situations. Despite these interventions, many patients remain anemic and do not respond to conventional treatment approaches. However, various novel therapies are being developed to treat persistent anemia in patients.
