The association of anatomical renal mass complexity with surgical approach, Hb drop, and the rate of blood transfusion.

INTRODUCTION: The third most prevalent malignant neoplasm involving the urinary tract is renal cell carcinoma (RCC), encompassing nearly 3.5% of the entire cancers afflicting the body. The aim of this research was to explore how the R.E.N.A.L. nephrometry score relates to the decisions made regarding surgery in individuals with localized RCC. METHODS: This prospective study, assessed patients with localized parenchymal renal masses (stages I and II) tentatively diagnosed as RCC. Utilizing preoperative multiphasic renal CT scans and MRI, the R.E.N.A.L. score categorized masses for nephrometry values. Inclusion criteria involved collecting patient data, and data collection utilizing a structured format focusing on the nephrometry grading system. RESULTS: The study included 64 patients aged (mean ± SD) 49.78 ± 12.35 yrs. Undergoing renal mass surgery, there were 17 (26.5%) low, 28 (43.8%) moderate and 19 (29.7%) high-complexity lesions. All patients with a low Nephrometry score (n = 17) underwent partial nephrectomy, and all cases with a high score (n = 19) underwent radical nephrectomy. For those with a moderate Nephrometry score (n = 28), 13 (46.4%) underwent partial nephrectomy, while the remaining 15 (53.6%) cases underwent radical nephrectomy. Morbidity was low, and no mortality occurred at 180 days. Patients who had lesions fully above or below polar lines were less likely to need blood transfusions. A trend towards higher Fuhrman grades in patients receiving transfusions suggests a potential link between tumor aggressiveness and bleeding risk. CONCLUSIONS: Our findings provide insight on the utilization of the R.E.N.A.L. nephrometry score in forecasting perioperative, post-surgical, and oncological results. Such data might help optimize surgical methods and pre-operative patient counseling.

Thyroid Status in Children with Transfusion Dependent Thalassemia in a Tertiary Level Hospital.

Most of the thalassemic children of Bangladesh are receiving repeated blood transfusion. But they do not receive chelation therapy due to financial constraints. As a result, iron overload occurs in various organs of these children. Extra iron that is loaded in thyroid gland causes thyroid dysfunction. This study was undertaken to evaluate thyroid status in children with transfusion dependent Thalassemia patient. This cross-sectional analytical study was conducted in the Department of Pediatrics, Mymensingh Medical College Hospital, Bangladesh from September 2016 to April 2018. Children having thalassemia diagnosed by Hb electrophoresis, aged 3-12 years of both sexes were included as study group. Children of same age and sex admitted in indoor of Mymensingh Medical College Hospital with minor illness and without thalassemia were taken as comparison group. Purposive Sampling technique was applied. Serum FT4, TSH and ferritin level were estimated in all children. Data analysis was done with Statistical Package for Social Science (SPSS) version 21.0. A total of 60 patients were enrolled as study group and another 60 patients were compared as comparison group. Mean ages of study group was 7.88±2.55 years and comparison group were 7.22±2.48 years. The mean pre-transfusion hemoglobin, serum ferritin, serum FT4 and serum TSH level were found 6.23±0.60 gm/dl, 2658.33±879.39 ng/ml, 15.14±4.40 fmol/mL, 4.29±4.60 µIU/mL respectively in study group. The mean serum FT4 was found significantly lower and mean serum TSH was significantly higher in thalassemic children in comparison to non-thalassemic children (p= <0.05). Frequency of subclinical hypothyroidism was found significantly higher in study group (25.0%) compared to comparison group (3.3%) (p=0.001). Mean serum ferritin level was found significantly higher in hypothyroid cases. Mean FT4 level was significantly lower and mean TSH level was significantly higher in hypothyroid thalassemic patients (p= <0.001). Significant positive correlation between serum ferritin level and serum TSH level was found. Higher serum ferritin level was found significantly associated with the development of hypothyroidism in thalassemic patients.

The effect of high-normal preoperative international normalized ratios on postoperative outcomes and complications following posterior cervical spine surgery.

INTRODUCTION: Current guidelines recommend that the International Normalized Ratio (INR) be less than 1.5 prior to spine intervention. Recent studies have shown that an INR > 1.25 is associated worse outcomes following anterior cervical surgery. We sought to determine the risk of complications associated with an INR > 1.25 following elective posterior cervical surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried. Patients undergoing elective posterior cervical surgery from 2012 to 2016 with an INR level within 24 h of surgery were included. Primary outcomes were hematoma requiring surgery, 30-day mortality, and transfusions within 72-hours. There were 815 patients in the INR ≤ 1 cohort (Cohort A), 410 patients in the 1 < INR ≤ 1.25 cohort (Cohort B), and 33 patients in the 1.25 < INR ≤ 1.5 cohort (Cohort C). RESULTS: Cohort C had a higher rate of transfusion (4% Cohort A; 6% Cohort B; 12% Cohort C; p = 0.028) and the rate of mortality within 30 days postoperatively trended toward significance (0.4% Cohort A; 0.5% Cohort B; 3% Cohort C; p = 0.094). There was no significant difference in the rate of postoperative hematoma formation requiring surgery (0.2% Cohort A; 0% Cohort B; 0% Cohort C; p = 0.58). On multivariate analysis, increasing INR was not associated with an increased risk of developing a major complication. CONCLUSION: An INR > 1.25 but ≤ 1.5 may be safe for posterior cervical surgery. An INR > 1.25 but ≤ 1.5 was associated with a significantly higher rate of transfusions. However, increasing INR was not significantly associated with increased risk of any of the major complications.

Prevalence and Factors Associated with transfusion-transmissible infections among blood donors in Arua regional blood bank, Uganda.

BACKGROUND: Blood transfusion services play a very key role in modern health care service delivery. About 118.5 million blood donations were collected globally in 2022. However, about 1.6 million units of blood are destroyed annually due to transfusion-transmissible infections (TTIs). There is a very high risk of TTIs through donated blood to recipients if safe transfusion practices are not observed. This study determined the prevalence and factors associated with TTIs among blood donors in Arua regional blood bank, Uganda. METHODS: This study was a retrospective cross-sectional design that involved a review of a random sample of 1370 blood donors registered between January 1st, 2018 and December 31st, 2019 at Arua regional blood bank, Uganda. Descriptive statistics were used to describe the characteristics of the blood donors. The binary logistic regression was used to determine the factors associated with TTIs. RESULTS: The majority of the blood donors were male (80.1%), and the median donor age was 23 years (IQR = 8 years). The overall prevalence of TTIs was found to be 13.8% (95%CI: 12.0-15.6%), with specific prevalences of 1.9% for HIV, 4.1% for HBV, 6.6% for HCV and 2.8% for treponema pallidum. Male sex (AOR = 2.10, 95%CI: 1.32-3.36, p-value = 0.002) and lapsed donor type compared to new donor type (AOR = 0.34, 95%CI: 0.13-0.87, p-value = 0.025) were found to be associated with TTIs. CONCLUSION: The prevalence of TTIs among blood donors of West Nile region, Uganda was found to be significantly high, which implies a high burden of TTIs in the general population. Hence, there is need to implement a more stringent donor screening process to ensure selection of risk-free donors, with extra emphasis on male and new blood donors. Additionally, sensitization of blood donors on risky behaviors and self-deferral will reduce the risk of donating infected blood to the recipients.

Evaluation of the efficacy of perioperative tranexamic acid in patients with pelvic and acetabular fractures: A systematic review and meta-analysis.

BACKGROUND: Tranexamic acid (TXA) is commonly used to reduce perioperative bleeding in various surgeries, including acetabular and pelvic fractures treated with open reduction and internal fixation (ORIF). However, research on TXA's effectiveness and safety in this context is conflicting. To address this, we conducted a systematic review and meta-analysis on TXA's efficacy and safety in patients with acetabular and pelvic fractures undergoing ORIF. METHODS: We systematically searched Cochrane, PubMed, and EMBASE databases until August 30, 2023. Our evaluation of TXA focused on 6 domains: estimated blood loss (EBL), blood transfusion units, transfusion rates, thromboembolic events, other complications, and surgery duration. Data from these studies were analyzed using RevMan Manager 5.4. RESULTS: This study included 4 randomized controlled trials with 179 patients with acetabular and pelvic fractures treated with TXA. The analysis showed that TXA did not significantly reduce EBL, packed red blood cell transfusion units, blood transfusion rates, or surgery duration. There was no significant difference in thromboembolic events or other postoperative complications, like surgical wound issues, pneumonia, heterotopic ossification, and sciatic nerve injuries, between the TXA and control groups. CONCLUSION: TXA did not demonstrate a significant benefit in reducing perioperative bleeding or complications in patients treated with ORIF for acetabular and pelvic fractures. The utilization of TXA in such clinical scenarios remains a topic necessitating further rigorous investigation to delineate its role in this clinical setting.

Impact of the COVID-19 Pandemic on Blood Transfusion among Hospitalized Patients with Chronic Kidney Disease.

Background and Objectives: Hematological disorders, especially chronic anemia and coagulation disorders, are common in patients with chronic kidney disease (CKD). Severe anemia is associated with increased cardiovascular morbidity and mortality in this special group of patients and is also responsible for decreased hope and quality of life. Despite the use of appropriate iron therapy and erythropoietin-stimulating agents, red blood cell transfusion is occasionally required, usually in the setting of acute bleeding or for correction of perioperative anemia. The COVID-19 pandemic has accelerated the progression of chronic diseases and worsened the outcomes for patients with nephrological conditions. As a precautionary measure against infections, patients' access to hospitalization for their procedures has been reduced and their chronic complications, including hematological abnormalities, have gotten out of control. Materials and Methods: Our retrospective observational study was designed to evaluate the impact of the COVID-19 pandemic on blood transfusion for the patients with chronic kidney disease hospitalized in our emergency county medical unit, over a period of four years (2019-2022) who were admitted or at least referred for evaluation to the Nephrology department. We also followed the measures adopted to ensure the necessary blood products during this time. Results: Between 2190-2022, a total of 24,096 hospitalized patients were transfused at the Emergency County Clinical Hospital in Constanta, Romania. Meanwhile, in the nephrology and other medical or surgical wards of our medical unit, 1590 CKD patients were transfused with different blood derivatives. During the pandemic years, as expected, the number of transfused patients and transfused blood units decreased by 4% and 7%, respectively, in comparison with the pre-pandemic year, 2019. Unlike the general trend of transfusion activity, more patients with CKD transfused in 2022 (580) than before the pandemic (414 in 2019), and the number of blood units was higher in 2022 than in 2019 for red blood products and plasma. Between 2020-2022, from the total number of transfused patients in our study, 254 with CKD patients (16%) and 798 non-CKD (4%) died in-hospital. Conclusions: The adaptive strategies implemented to ensure the necessary blood products in the hospital during the COVID-19 pandemic mainly included restrictive transfusion and limitation of elective surgical procedures. The subject matter of the article is important as blood shortages are a problem that healthcare workers may encounter in future pandemics.

Intraoperative Bleeding Complications Leading to Blood Transfusions (BloTs) in 17,412 Cholecystectomies in Finland: A Study With Special Reference to Elderly Patients.

BACKGROUND/AIM: Cholelithiasis (Chole) is one of the most common diseases needing operative management worldwide. However, there are few studies assessing the intraoperative bleeding (IOB) complications leading to blood transfusions (BloTs) in elderly patients with cholecystectomy (Ccy). PATIENTS AND METHODS: Outcome after IOB complications and need for BloTs in a cohort of 17,412 patients with Ccys were assessed with special reference to elderly Ccy patients. RESULTS: A total of 17,412 patients underwent Ccy and 11% of Ccy patients (1,856/17,412) were aged ≥75 years. The Ccy patients ≥75 years underwent more often emergency/open Ccys. Red blood cell BloTs were administered five times more often to Ccy patients ≥75 years versus Ccy patients <75 years (13% versus 2.6%, p<0.001). In Ccys by emergency surgery indications, the need for BloTs was four times higher in Ccy patients ≥75 years versus Ccy patients <75 years (5.5% versus 1.3%, p<0.001). CONCLUSION: The elderly Chole patients have a higher risk than younger Chole patients for perioperative IOB complications and thus are more likely to need BloTs.

The effects of prophylactic administration of tranexamic acid on the operative time and the amount of blood transfused during open fixation of pelvis and acetabulum fractures.

BACKGROUND: Orthopedic surgeons face challenges regarding perioperative bleeding during the operations of pelvic and acetabular fracture cases. Although the recently popular tranexamic acid (TXA) has proven to be a useful tool, this study primarily aimed to conduct a retrospective comparative analysis of the results of the prophylactic administration of tranexamic acid during open fixation of pelvis and acetabulum fractures, especially regarding operative time and the amount of blood transfused; and in addition, share the results related to other findings including the management of the erythrocyte suspension use and overall cost as secondary aims and thus providing a comprehensive point of view. METHODS: The files of patients with pelvis or acetabulum fractures admitted to the Emergency Clinic of the Adana City Training and Research Hospital between January 1, 2020, and December 31, 2023, were analyzed retrospectively. The inclusion criteria were as follows: patients aged 18 years or older who had undergone open reduction for pelvis or acetabulum fractures. RESULTS: There were 78 files identified for analysis. Among the fractures, 27 were located at the pelvis (34.61%) and 51 at the acetabulum (65.38%). The pelvic fracture cases' age and preoperative hemoglobulin levels were significantly lower (p = 0.019 and p = 0.006, respectively). When all cases were dichotomized into two groups, ones requiring ICU monitoring and the remaining, there were statistically significant differences in terms of the preoperative hemoglobin levels (p = 0.0446), intraoperative bleeding (p = 0.0134), units of erythrocyte suspension used (p = 0.0066), drain output (p = 0.0301), hospitalization duration (p = 0.0008), and the overall cost (p = 0.0002). The comparison regarding TXA use showed that the use of blood products was significantly higher in the pelvic fractures not treated with TXA (6.44 ± 4.42 units, p = 0.0029). The duration of surgery was shorter for pelvic fractures treated with TXA (98.33 ± 21.76 min, p = 0.047). CONCLUSION: Among the variables, the amount of intraoperative bleeding emerged as the most correlated element, which strongly suggests that in managing open reduction internal fixation surgeries performed for pelvis and acetabulum fractures, intraoperative bleeding should be considered as the crucial factor. Therefore, the administration of TXA, by effectively reducing the amount of intraoperative bleeding, should be considered as an essential tool for orthopedic surgeons.

Tranexamic Acid Administered at Time of Hospital Admission Does Not Decrease Transfusion Rates or Blood Loss for Extracapsular Hip Fractures: A Double-Blinded Randomized Clinical Trial.

OBJECTIVES: To evaluate tranexamic acid (TXA) when administered immediately on hospital presentation in patients with extracapsular peritrochanteric hip fractures to determine its effect on (1) transfusion rates, (2) estimated blood loss, and (3) complications. DESIGN: Prospective, double-blinded, randomized clinical trial. SETTING: Single-center, Level 1 trauma center. PATIENT SELECTION CRITERIA: All patients with isolated OTA/AO 31-A fracture patterns from 2018 to 2022 were eligible for inclusion. Study drug was administered in the emergency department at the time of presentation-1-g bolus over 10 minutes followed by a 1-g infusion over 8 hours. OUTCOME MEASURES AND COMPARISONS: The primary outcome was the rate of red blood cell transfusion hospital days 1-4. Secondary outcomes included estimated blood loss and complications including venous thromboembolic events, stroke, myocardial infarction, all-cause 90-day readmissions, and all-cause mortality. RESULTS: One hundred twenty-eight patients were included-64 patients were randomized to intravenous TXA and 64 patients to intravenous normal saline (ie, placebo). There was no difference in the rate of red blood cell transfusion between treatment arms between hospital days 1-4 (27% in the TXA arm vs. 31% in the placebo arm, P = 0.65). Patients randomized to placebo who required transfusion received a mean of 2.30 units compared with 1.94 units in the TXA cohort (P = 0.55). There was no difference in the estimated blood loss between hospital days 1-4. There was no difference in the incidence of postoperative complications including venous thromboembolic events, stroke, myocardial infarction, 90-day readmission, or death. CONCLUSIONS: The results of this study do not support the use of preoperative TXA for reducing blood loss for geriatric patients with extracapsular hip fractures. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Whole Blood Program: Implementation in a Rural Trauma Center.

BACKGROUND: The balanced transfusion of blood components plays a leading role in traumatic hemostatic resuscitation. Yet, previous whole blood studies have only focused on urban trauma center settings. OBJECTIVE: To compare component vs whole blood therapy on wastage rates and mortality in the rural setting. METHODS: This study was a nonrandomized, retrospective, observational, single-center study on a cold-stored whole blood program implementation for adult massive transfusions from 2020 to 2022 at a Level II trauma center. Trauma registry data determined the facility's whole blood needs and facilitated sustainable blood supplies. Whole blood use protocols were established, and utilization and laboratory compliance for incompatible ABO antibody hemolysis was monitored and reviewed monthly at stakeholder and trauma services meetings. RESULTS: From 2018 to 2019, the facility initiated component therapy massive transfusions every 9 days (n = 41). Therefore, four units of low-titer, O-positive whole blood delivered fortnightly was determined to provide patient coverage and minimize wastage. Across the study time frame (2020-2022), there were n = 68 hemodynamically unstable patients, consisting of those receiving whole blood, n = 37, and patients receiving component therapy, n = 31. Mortality rates were significantly lower (p = .030) in the whole blood population (n = 3, 8%) compared to those solely receiving component therapy (n = 9, 29%). Wastage rates were constantly evaluated; in 2021, 43.4% was not utilized, and in 2022, this was reduced to 38.7%. Anecdotally, nurses appreciated the ease of administration and documentation of transfusing whole blood, as it negated ratio compliance. CONCLUSION: This evidence-based whole blood program provides vital care to severely injured trauma patients in a vast, rural region.

The role of prophylactic transfusion on the maternal and fetal outcomes in pregnant women with sickle cell disease: A systematic review and meta-analysis.

BACKGROUND: In the present review, we aimed to synthesize evidence from studies on the safety and effectiveness of prophylactic blood transfusion in pregnant women with sickle cell disease. MATERIAL AND METHODS: To gather relevant information, we conducted systematic electronic searches of databases such as SCOPUS, Medline via PubMed, Web of Science, and Cochrane Central Register of Controlled Trials. We included both retrospective and prospective studies that examined the impact of prophylactic blood transfusions during pregnancy. The collected data were analyzed using Review Manager, version 5.3. RESULTS: The review included 15 cohort studies. The overall findings indicated a preference for the prophylactic blood transfusion group over the control group across several key parameters. Specifically, the prophylactic group demonstrated lower rates of maternal mortality (odds ratio [OR] = 0.33; 95% confidence interval [CI] = 0.10-1.13; P = .08), reduced incidence of vaso-occlusive painful events (OR = 0.31; 95% CI = 0.14-0.73; P = .007), fewer pulmonary complications (OR = 0.21; 95% CI = 0.08-0.53; P = .001), decreased perinatal mortality (OR = 0.35; 95% CI = 0.17-0.75; P = .03), and lower likelihood of preterm birth (OR = 0.67; 95% CI = 0.47-0.96; P = .02). Notably, statistically significant heterogeneities were observed in the pooled effect estimates. CONCLUSION: The present meta-analysis indicated that prophylactic blood transfusion in pregnant women with sickle cell disease may improve maternal and fetal outcomes. However, substantial variations in the methodology and transfusion protocols among the included studies limited the credibility of the current evidence supporting the routine clinical use of prophylactic transfusion for SCD during pregnancy.

Preoperative low serum albumin increases the rate of perioperative blood transfusion in patients undergoing total joint arthroplasty: propensity score matching.

BACKGROUND: To investigate the relationship between preoperative low serum albumin and perioperative blood transfusion in patients undergoing total joint arthroplasty (TJA). METHODS: We enrolled 2,772 TJA patients from our hospital between January 1, 2017, and January 1, 2022. Clinical data were extracted from electronic medical records, including patient ID, sex, BMI (Body Mass Index), age, and diagnoses. Receiver operating characteristic curves were constructed to establish thresholds for serum albumin levels categorization. Propensity score matching (PSM) was developed with preoperative serum albumin as the dependent variable and perioperative blood transfusion-related factors as covariates, including BMI grade, age grade, sex, diagnosis, hypertension, diabetes, coronary heart disease, chronic obstructive pulmonary disease, chronic bronchitis, cerebral infarction, major surgeries within the last 12 months, renal failure, cancer, depression, corticosteroid use, smoking, drinking, and blood type. The low serum albumin group was matched with the normal albumin group at a 1:2 ratio, employing a caliper value of 0.2. Binary logistic regression was employed to analyze the outcomes. RESULTS: An under the curve of 0.601 was discovered, indicating a cutoff value of 37.3 g/L. Following PSM, 892 cases were successfully paired in the low serum (< 37.3 g/L) albumin group, and 1,401 cases were matched in the normal serum albumin (≥ 37.3 g/L) group. Binary logistic regression in TJA patients showed that the albumin OR was 0.911 with 95%CI 0.888-0.935, P < 0.001. Relative to the preoperative normal serum albumin group, TJA patients in the low serum albumin group experienced a 1.83-fold increase in perioperative blood transfusion rates (95% CI 1.50-2.23, P < 0.001). Compared to the normal serum albumin group, perioperative blood transfusion rates for TJA patients with serum albumin levels of 30-37.3 g/L, 25-30 g/L, and ≤ 25 g/L increased by 1.63 (95% CI 1.37-1.99, P < 0.001), 5.4 (95% CI 3.08-9.50, P < 0.001), and 6.43 times (95% CI 1.80-22.96, P = 0.004), respectively. CONCLUSION: In TJA patients, preoperative low serum albumin levels have been found to be associated with an increased risk of perioperative blood transfusion. Furthermore, it has been observed that the lower the preoperative serum albumin level is, the higher the risk of perioperative blood transfusion.

The global blood donation index: an imperfect measure of transfusion need.

The optimum number of units of blood and the associated number of blood donors required to meet a given population's needs remain undetermined globally. Typically, a whole blood donation rate of ten donations per 1000 population, at a minimum, is necessary to meet a country's blood needs. This rate is attributed to a WHO recommendation that 1% of a given country's population should donate blood to ensure a blood supply that is sufficient to meet clinical needs. This often cited metric was first referenced in a 1971 WHO report, yet neither supporting data or references were provided, suggesting that it was flawed at its founding. Regardless, this metric does not provide an accurate or contemporary determination of blood needs, which has ramifications for health service provision and planning, particularly in low-income and lower-middle-income countries. Modelling studies that account for geographical variability in disease burden, health-care infrastructure, and transfusion practices are needed to accurately estimate blood needs. A paucity of data to inform modelling remains a major obstacle in this regard. We discuss the history of the global blood donation index and highlight some factors that should be considered to better understand contemporary blood needs.

Safe to save blood in ovarian cancer surgery - time to change transfusion habits.

BACKGROUND: Patients with advanced ovarian cancer (AOC) undergoing surgery are often subjected to red blood cell (RBC) transfusions. Both anemia and RBC transfusion are associated with increased morbidity. The aim was to evaluate patient recovery after the implementation of patient blood management (PBM) strategies. METHODS: This retrospective cohort study included 354 patients with AOC undergoing surgery at Skane University Hospital Lund, Sweden, between January 2016 and December 2021. The gradual implementation of PBM strategies included restrictive RBC transfusion, tranexamic acid as standard medication before laparotomies and intravenous iron administered to patients with iron deficiency. Severe complications were defined as Clavien-Dindo (CD) grade ≥ 3a. Logistic and linear regression analyses were used to evaluate the differences between three consecutive periods. RESULTS: After the implementation of new strategies, 52% of the patients had at least one transfusion compared to 83% at baseline (p < 0.001). There was no difference in the rate of severe complications (CD ≥ 3a) between the groups, adjusted odds ratio 0.55 (95% CI 0.26-1.17). The mean difference in hemoglobin before chemotherapy was -1.32 g/L (95% CI -3.04 to -0.22) when adjusted for blood loss and days from surgery to chemotherapy. The length of stay (LOS) decreased from 8.5 days to 7.5 days (p 0.002). INTERPRETATION: The number of patients transfused were reduced by 31%. Despite a slight increase in anemia rate, severe complications (CD ≥ 3a) remained stable. The LOS was reduced, and chemotherapy was given without delay, indicating that PBM is feasible and without causing major severe effects on short-term recovery.

Impact of perioperative hemoglobin-related parameters on clinical outcomes in patients with spinal metastases: identifying key markers for blood management.

PURPOSE: Patients with spinal metastases undergoing surgical treatment face challenges related to preoperative anemia, intraoperative blood loss, and frailty, emphasizing the significance of perioperative blood management. This retrospective analysis aimed to assess the correlation between hemoglobin-related parameters and outcomes, identifying key markers to aid in blood management. METHODS: A retrospective review was performed to identify patients who underwent surgical treatment for spinal metastases. Hb-related parameters, including baseline Hb, postoperative nadir Hb, predischarge Hb, postoperative nadir Hb drift, and predischarge Hb drift (both in absolute values and percentages) were subjected to univariate and multivariate analyses. These analyses were conducted in conjunction with other established variables to identify independent markers predicting patient outcomes. The outcomes of interest were postoperative short-term (6-week) mortality, long-term (1-year) mortality, and postoperative 30-day morbidity. RESULTS: A total of 289 patients were included. Our study demonstrated that predischarge Hb (OR 0.62, 95% CI 0.44-0.88, P = 0.007) was an independent prognostic factor of short-term mortality, while baseline Hb (OR 0.76, 95% CI 0.66-0.88, P < 0.001) was identified as an independent prognostic factor of long-term mortality. Additionally, nadir Hb drift (OR 0.82, 95% CI 0.70-0.97, P = 0.023) was found to be an independent prognostic factor for postoperative 30-day morbidity. CONCLUSIONS: This study demonstrated that predischarge Hb, baseline Hb, and nadir Hb drift are prognostic factors for outcomes. These findings provide a foundation for precise blood management strategies. It is crucial to consider Hb-related parameters appropriately, and prospective intervention studies addressing these markers should be conducted in the future.

An analysis of the effect of low titer O whole blood (LTOWB) proportions for resuscitation after trauma on 6-hour and 24-hour survival.

INTRODUCTION: Hemorrhage is a leading cause of death. Blood products are used for the treatment of hemorrhagic shock. The use of low titer group O whole blood (LTOWB) has become more common. METHODS: Data from patients ≥15 years of age in the Trauma Quality Improvement Program (TQIP) database that received ≥10 units of packed red cells and/or LTOWB within the first 4-h of hospital arrival were included. The proportion of LTWOB of total blood products administered was correlated to 6- and 24-h mortality. RESULTS: 12,763 met inclusion, 3827 (30 %) received LTOWB. On multivariable logistic regression (MVLR), there was no difference in survival at 6 h with a LTOWB. When assessing 24-h survival, there was improved survival with LTOWB ≥10 % (OR 1.18, 1.08-1.28). CONCLUSIONS: In this analysis of TQIP data, patients receiving ≥10 units of PRBC or LTOWB, we found that higher proportions of LTOWB transfusion relative to the total volume of blood products transfused during the first 4 h were associated with improved 24-h, but not 6-h survival.

Hepatic resections for pediatric hepatoblastoma: analysis of 30-day outcomes using the National Surgical Quality Improvement Program-Pediatric database.

BACKGROUND: Surgical resection remains the cornerstone of treatment for hepatoblastoma in children and offers the best chance of disease-free survival. We aimed to analyze the 30 day outcomes of hepatic resection for hepatoblastoma stratified by extent using the National Surgical Quality Improvement Program-Pediatric (NSQIP-P). METHODS: We queried NSQIP-P for children undergoing resection of Hepatoblastoma from 2012 to 2021. Relevant clinical characteristics and outcomes were extracted for multivariate logistic regression to identify predictors of common adverse outcomes. RESULTS: We included 458 children with a median age of 1.90 years. Overall complications were rare, and perioperative blood transfusion (64.2%) and postoperative ventilation > 48 h (10.0%) were the only adverse events prevalent in more than 5% of patients. Median transfusion volume was 15.7 ml/kg. On multivariate regression, only patients undergoing Trisectionectomy (aOR = 3.387, 95% C.I. = 1.348-8.510) had higher odds of receiving > 75th percentile blood transfusion. Furthermore, only perioperative transfusion and postoperative ventilation > 48 h were statistically more common in patients undergoing extended versus standard resections. CONCLUSIONS: Outcomes following resection of hepatoblastoma are excellent, with low rates of postoperative adverse events. Although children undergoing trisectionectomy likely require greater transfusion volume, extended hepatic resections do not appear to have worse 30 day outcomes despite greater operative complexity and duration.

Influence of the leukoreduction moment of blood components on the clinical outcomes of transfused patients in the emergency department.

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

The anterior-based muscle-sparing approach is cost-effective when compared with posterolateral and direct anterior approaches for total hip arthroplasty.

PURPOSE: Research relating to Total Hip Arthroplasty (THA) has found the anterior-based muscle-sparing (ABMS) approach improves both intraoperative and postoperative outcomes when compared to other THA approaches. This study compares the costs and outcomes of the ABMS approach and standard of care (SOC) to determine the relative cost-effectiveness. METHODS: A decision-analytic model was utilized to estimate intraoperative outcomes (i.e. length of procedure, length of stay (LOS), and transfusion rates) and 90-day postoperative complications (deep infection, periprosthetic fracture, and dislocation). Data relating to postoperative complications, intraoperative outcomes, and costs (adjusted to 2023 USD) were obtained from the literature. Model results were presented as incremental costs and complications avoided using a willingness-to-pay threshold of $100,000. We conducted both one-way sensitivity analysis (OWSA), varying each parameter individually within a specific range, and probabilistic sensitivity analysis (PSA) where parameters were varied simultaneously. In scenario analysis, ABMS was also compared to the posterior approach (PA) and direct anterior approach (DAA) individually. RESULTS: ABMS THA was found to have superior results compared to SOC THA over a 90-day time horizon since it decreased major complications by 0.00186 per patient and cost by $3,851 per patient. The PSA found the ABMS approach dominates SOC and is cost-effective in approximately 98.29% and 100% of 10,000 iterations, respectively. Comparing ABMS with only PA procedures increased cost savings per patient to $4,766 while it decreased to $3,242 when comparing ABMS to only DAA procedures. Length of procedure, LOS, and discharge disposition were the main cost drivers. CONCLUSIONS: This analysis demonstrates the ABMS approach for THA is a cost-effective technique when compared to PA and DAA, which may provide an opportunity for cost savings to the healthcare system.
