Development and Validation of a Machine Learning Algorithm to Predict the Risk of Blood Transfusion after Total Hip Replacement in Patients with Femoral Neck Fractures: A Multicenter Retrospective Cohort Study. Orthop Surg 2024. [PMID: 38951965 DOI: 10.1111/os.14160] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 06/13/2024] [Accepted: 06/16/2024] [Indexed: 07/03/2024] Open
Abstract
OBJECTIVE Total hip arthroplasty (THA) remains the primary treatment option for femoral neck fractures in elderly patients. This study aims to explore the risk factors associated with allogeneic blood transfusion after surgery and to develop a dynamic prediction model to predict post-operative blood transfusion requirements. This will provide more accurate guidance for perioperative humoral management and rational allocation of medical resources. METHODS We retrospectively analyzed data from 829 patients who underwent total hip arthroplasty for femoral neck fractures at three third-class hospitals between January 2017 and August 2023. Patient data from one hospital were used for model development, whereas data from the other two hospitals were used for external validation. Logistic regression analysis was used to screen the characteristic subsets related to blood transfusion. Various machine learning algorithms, including logistic regression, SVA (support vector machine), K-NN (k-nearest neighbors), MLP (multilayer perceptron), naive Bayes, decision tree, random forest, and gradient boosting, were used to process the data and construct prediction models. A 10-fold cross-validation algorithm facilitated the comparison of the predictive performance of the models, resulting in the selection of the best-performing model for the development of an open-source computing program. RESULTS BMI (body mass index), surgical duration, IBL (intraoperative blood loss), anticoagulant history, utilization rate of tranexamic acid, Pre-Hb, and Pre-ALB were included in the model as well as independent risk factors. The average area under curve (AUC) values for each model were as follows: logistic regression (0.98); SVA (0.91); k-NN (0.87) MLP, (0.96); naive Bayes (0.97); decision tree (0.87); random forest (0.96); and gradient boosting (0.97). A web calculator based on the best model is available at: (https://nomo99.shinyapps.io/dynnomapp/). CONCLUSION Utilizing a computer algorithm, a prediction model with a high discrimination accuracy (AUC > 0.5) was developed. The logistic regression model demonstrated superior differentiation and reliability, thereby successfully passing external validation. The model's strong generalizability and applicability have significant implications for clinicians, aiding in the identification of patients at high risk for postoperative blood transfusion.

Arthroscopy 2023; 39:2529-2546.e1. [PMID: 37683831 DOI: 10.1016/j.arthro.2023.08.019] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Revised: 08/06/2023] [Accepted: 08/08/2023] [Indexed: 09/10/2023]
Abstract
PURPOSE To investigate whether tranexamic acid (TXA) is cytotoxic in chondrocyte and cartilage tissues, as well as explore the mechanisms behind the possible toxicity in detail. METHODS We detected the cell viability of chondrocytes in vitro and the change of morphology and specific in vivo contents of cartilage after TXA treatment. Furthermore, we detected apoptosis in cartilage. We used apoptosis-specific staining, reactive oxygen species detection, mitochondrial membrane potential detection, flow cytometry, and western blot for apoptosis detection. Finally, we detected the activation of endoplasmic reticulum stress (ERS) in TXA-treated chondrocytes to clarify the mechanism behind chondrocyte apoptosis. RESULTS TXA presented an increasing toxic effect with increasing concentrations, especially in the 100 mg/mL group. In addition, we found that 50 mg/mL and 100 mg/mL TXA significantly increased apoptosis in cartilage and subchondral bone. TXA could induce chondrocyte apoptosis in cell and protein levels with reactive oxygen species generation and mitochondrial membrane depolarization. An apoptosis inhibitor could inhibit the induced apoptosis. Next, TXA induced calcium overload in chondrocytes and increased ERS-specific protein expression, whereas ERS inhibitor blocked ERS activation and further inhibited chondrocyte apoptosis. CONCLUSIONS We concluded that TXA had a toxic effect on chondrocytes by inducing apoptosis through ERS activation, especially in 50 mg/mL and 100 mg/mL groups. We recommend TXA concentrations of less than 50 mg/mL in joint surgeries. CLINICAL RELEVANCE It is still unclear whether TXA has a toxic effect on cartilage when topically used in joint surgeries. The concentration also varies. This study provides additional evidence that TXA at high concentrations will cause cartilage damage, which will help to provide a new understanding of the clinical administration of TXA.

Medicine (Baltimore) 2023; 102:e33876. [PMID: 38013364 PMCID: PMC10681596 DOI: 10.1097/md.0000000000033876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Accepted: 05/08/2023] [Indexed: 11/29/2023] Open
Abstract
BACKGROUND Tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA) have been demonstrated to reduce blood loss following total knee arthroplasty (TKA). This meta-analysis aimed to compare the efficacy and safety of TXA and EACA in reducing blood loss in primary TKA patients. METHODS A search of the PubMed, Embase, and Cochrane Library databases identified all relevant studies published until December 2022. Randomized controlled trials (RCTs) reporting a comparison of TXA and EACA for TKA patients were selected. The main outcomes were total blood loss (TBL), hemoglobin (Hb) drop on postoperative day 3, intraoperative blood loss, operation time and the transfusion rate were evaluated. The weighted mean differences (WMD) and risk ratio (RR) with 95% confidence intervals (CI) were calculated using a fixed-effects or random-effects model. Stata 12.0 software was used for meta-analysis. RESULTS Six studies involving 739 (TXA:372; EACA:367) patients were included in this meta-analysis. There was no significant difference in terms of intraoperative blood loss, Hb drop on postoperative day 3, operation time, tourniquet time (TT), transfusion rate and the occurrence of deep venous thrombosis (DVT) between the 2 treatments groups. However, compared with EACA, TXA significant reduced TBL (WMD, 174.60; 95% CI, -244.09 to -105.11). CONCLUSION Our research did not demonstrate TXA to be superior to EACA in reducing need for transfusion and Hb drop. TXA was superior than EACA in reducing TBL in TKA patients. More RCTs with identical inclusion criteria and dose and duration of treatment, are required to confirm these findings.

Tranexamic acid is safe with respect to the risk of deep venous thrombosis in patients with hemophilic arthritis undergoing total knee arthroplasty without chemoprophylaxis: A prospective study. Knee 2023; 44:165-171. [PMID: 37672907 DOI: 10.1016/j.knee.2023.08.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 06/11/2023] [Accepted: 08/06/2023] [Indexed: 09/08/2023]
Abstract
BACKGROUND Pharmacologic thromboprophylaxis is controversial for hemophiliacs who undergo total joint replacements. The purpose of this study was to assess the safety of tranexamic acid (TXA) utilization with respect to the incidence of deep venous thrombosis (DVT) in hemophiliacs undergoing total knee arthroplasty (TKA). METHODS A total of 104 patients with hemophilic arthritis were included in the study. The patients were randomly divided into two groups of 52 subjects. All patients received a modified coagulation factor substitution regimen. In the TXA group, 1 g of TXA was injected intravenously 15 min before incision and 2 g of TXA was intra-articularly injected in the surgical area. A routine mechanical prophylaxis was administered to all patients under a standardized postoperative protocol. Thromboembolic complications in both groups were followed up for 2 years. RESULTS All patients were male and underwent 146 arthroplasties. There was a mean age of 33.2 ± 8.8 years and a mean body mass index of 22.2 ± 5.1 kg/m2. A 100% compliance rate was observed with mechanical prophylaxis. No asymptomatic DVT was detected on postoperative ultrasound in all patients. We also failed to find any proof of clinical venous thromboembolism in our patients during a 2-year follow up. Only two cases in the TXA group underwent blood transfusions (4.0%), while 29.2% of the patients in the non-TXA group needed transfusion. CONCLUSIONS This prospective study showed that TXA could be safely utilized in patients with hemophilic arthritis who underwent TKA without increasing the incidence of DVT and routine chemoprophylaxis may not be necessary.

Predictors and complications of blood transfusion in rheumatoid arthritis patients undergoing total joint arthroplasty. Clin Rheumatol 2023; 42:67-73. [PMID: 36121576 DOI: 10.1007/s10067-022-06376-9] [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: 04/20/2022] [Revised: 08/30/2022] [Accepted: 09/12/2022] [Indexed: 01/28/2023]
Abstract
PURPOSE Our research investigated predictors of postoperative blood transfusion rate following total joint arthroplasty (TJA) in patients with rheumatoid arthritis (RA) and evaluated the incidence of complications in the transfusion group and non-transfusion group. METHODS The authors retrospectively analyzed risk factors among 320 RA patients who underwent elective total hip arthroplasty (THA) or total knee arthroplasty (TKA) from January 2010 to December 2018. Demographic characteristics, laboratory results, medication history, and surgical protocol were gathered from electronic medical records. Univariable and multivariable logistic regression analyses were conducted to measure the impact of relevant variables on the need for transfusions. In addition, we compared the incidence of complications associated with transfusion. RESULTS The cohort comprised 320 RA patients, aged 57.4 ± 12.0 years, of whom 137 required postoperative blood transfusions and 183 did not. BMI, type of surgery, duration of surgery, disease activity score 28 (DAS28-CRP), tranexamic acid (TXA) administration, and preoperative hemoglobin (Hb) were all risk factors for transfusion after adjusting for the planned procedure. CONCLUSION Previously published predictors, such as BMI, low preoperative hemoglobin, duration of surgery, procedure type (THA), were also identified in our analysis. Moreover, TXA administration and the DAS28-CRP showed the potential to influence risk. The incidence of postoperative complications was increased in patients who received blood transfusions compared to non-transfusion group. Our findings could help to identify RA patient population requiring blood transfusions, to ensure the necessary steps are adopted to limit blood loss and improve blood management strategies. Key Points • The risk factors for blood transfusion in rheumatoid arthritis patients undergoing total joint arthroplasty were BMI, the type of surgery, duration of surgery, TXA administration, DAS28-CRP, and preoperative hemoglobin. • The incidence of postoperative complications was increased in patients who received blood transfusions compared to non-transfusion group.

Efficacy and safety of tranexamic acid for patients with intertrochanteric fractures treated with intramedullary fixation: A systematic review and meta-analysis of current evidence in randomized controlled trials. Front Pharmacol 2022; 13:945971. [PMID: 36199695 PMCID: PMC9528975 DOI: 10.3389/fphar.2022.945971] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 09/05/2022] [Indexed: 11/13/2022] Open
Abstract
Background: Tranexamic acid (TXA) has been widely applied to reduce perioperative bleeding. Recently, several studies focused on the administration of TXA in the treatment for with intertrochanteric fracture patients treated with intramedullary fixation. However, the efficacy and safety of TXA in these studies remain controversial. Therefore, we performed this systematic review and meta-analysis to investigate the efficacy and safety of TXA in intertrochanteric fracture patients treated with intramedullary fixation.Methods: We systematically searched electronic databases, including Cochrane, PubMed, and EMBASE, up to 16 May 2022. The efficacy and safety of TXA was evaluated in four aspects, which were bleeding-related outcomes, non-bleeding-related outcomes, thromboembolic events, and other complications. The outcomes of these studies were extracted and analyzed by RevMan Manager 5.4.Results: Finally, nine randomized controlled trials, involving nine hundred and seventy-two intertrochanteric fracture patients treated with TXA, were enrolled in this study. In the bleeding-related outcomes, TXA group was significantly lower than the control group in terms of total blood loss (MD = −219.42; 95% CI, −299.80 to −139.03; p < 0.001), intraoperative blood loss (MD = −36.81; 95% CI, −54.21 to −19.41; p < 0.001), hidden blood loss (MD = −189.23; 95% CI, −274.92 to −103.54; p < 0.001), and transfusion rate (RR = 0.64; 95% CI, 0.49 to 0.85; p = 0.002). Moreover, the postoperative hemoglobin on day 3 of the TXA group was significantly higher than that of the control group (MD = 5.75; 95% CI, 1.26 to 10.23; p = 0.01). In the non-bleeding-related outcomes, the length of hospital stays was significantly shorter in the TXA group (MD = −0.67; 95% CI, −1.12 to −0.23; p = 0.003). In terms of thromboembolic events, there was no significant differences between the TXA group and control group in deep vein thrombosis, pulmonary embolism, myocardial infarction, and ischemic stroke. As for complications and mortality, there was no significant differences between the TXA group and control group in respiratory infection, renal failure, and postoperative mortality within 1 year.Conclusion: TXA is an effective and safe drug for perioperative bleeding control in intertrochanteric fracture patients treated with intramedullary fixation. However, the long-term efficacy of TXA still needs to be investigated by large-scale multicenter randomized controlled trials.Level of evidence: II, Systematic review and Meta-analysis.Systematic Review Registration:https://inplasy.com/, identifier [INPLASY202280027]
