Abstract Aim This study was designed to explore the prevalence condition and risk factors of preoperative deep venous thromboembolism (DVT) in Chinese elderly with hip fracture. Methods From January 1, 2012, to December 31, 2018, 273 elderly over 70 years old with elective hip surgery were collected from the electronic medical records. Collected Data included demographic characteristics, comorbidities, ASA classification, types of surgeries, types of anesthesia, operation time, fracture to operation time, perioperative blood transfusion, preoperative hemoglobin level, anemia, blood-gas analysis, cardiac function, electrocardiograph, lower limb venous ultrasound and hospitalization time. Results In all patients, 15 patients (5.6%) had venographic evidence of DVT in affected limbs before surgery. Three of all patients received an temporary inferior vena cave filter placement. Fracture to surgery time, preoperative hemoglobin level, anemia, pulmonary disease and hospitalization time were statistically different between DVT group and non-DVT group (P<0.05 for all). Moreover, preoperative anemia (OR: 0.144, 95%CI: 0.026-0.799, P=0.027) and hospitalization time (OR: 1.135; 95%CI: 1.023-1.259, P=0.017) were the two independent risk factors for preoperative DVT. Conclusion Preoperative anemia and hospitalization time were independent risk factors for venous DVT in Chinese elderly with hip fracture.

Background Splenectomy is sometimes indicated for portal hypertension caused by cirrhosis, which is a risk for hepatic carcinogenesis. This study aimed to identify risk factors for hepatocellular carcinoma (HCC) development after splenectomy. Methods This retrospective study included 65 patients who underwent splenectomy for portal hypertension between 2009 and 2017. Cox regression analyses were performed to identify factors related to HCC development after splenectomy. The predictive index for HCC development was constructed from the results of multivariate analysis, and 3 risk-dependent groups were defined. Discrimination among the groups was estimated using Kaplan-Meier curves and the log-rank test. Results Post-splenectomy, 36.9% of patients developed HCC. In the univariate analysis, the etiology of cirrhosis (hepatitis C virus antibody, P = .005, and hepatitis B surface antigen, P = .008, referring to non-B and non-C patients, respectively), presence of HCC history ( P < .001), and preoperative hemoglobin level ( P = .007) were related to HCC development, and the presence of HCC history ( P = .002) and preoperative hemoglobin level ( P = .022) were independent risk factors. The predictive index classified three groups at risk; the hazards in each group were significantly different (low vs middle risk, P = .035, and middle vs high risk, P = .011). Discussion The etiology of cirrhosis, presence of HCC history, and hemoglobin level were associated with HCC development after splenectomy. The predictive model may aid in HCC surveillance after splenectomy for patients with portal hypertension.

Objectives: The amount of blood transfusion after knee arthroplasty seem to vary in different reported study. We carried out a retrospective study to analysis pre-operative risk factors for blood transfusion in patient whom underwent knee arthroplasty in our institution. Methods: A retrospective study of 190 patients treated with 194 procedure (186 unilateral knee arthroplasty, 4 bilateral knee arthroplasty) from November 2014 to October 2015 was analyzed. A univariate analysis was performed to establish the relationship between all variables and the need for postoperative transfusion. Variables that were determined to have significant relationship were include in a multivariable analysis.. Results: The univariate analysis revealed a significant relationship between need for postoperative blood transfusion and preoperative hemoglobin levels, surgical technique, arthrotomy approach, DVT prophylaxis, operative blood loss, surgical technique and surgeon experience. The multivariate analysis identified a significant relationship between need for transfusion and preoperative hemoglobin level, surgical technique and operative blood loss. Patients with a preoperative hemoglobin less than 12 g/dL had a 5.1 times greater risk of having a transfusion than those with a hemoglobin level ≥ 12 g/dL. The surgical technique with computer assisted surgery had a 0.15 times lesser risk of having a transfusion than those with the conventional technique. Conclusion: The preoperative hemoglobin level < 12 g/dL was shown to increase risk of the need for blood transfusion after knee arthroplasty, while computer assist surgery total knee arthroplasty was shown to decrease risk of blood transfusion. We suggest that patients with preoperative hemoglobin < 12 g/dL need to be crossmatching PRC in pre-operative steps.

Abstract Background This study aimed to explore the preoperative risk factors related to blood transfusion after hip fracture operations and to establish a nomogram prediction model. The application of this model will likely reduce unnecessary transfusions and avoid wasting blood products. Methods This was a retrospective analysis of all patients undergoing hip fracture surgery from January 2013 to January 2020. Univariate and multivariate logistic regression analyses were used to evaluate the association between preoperative risk factors and blood transfusion after hip fracture operations. Finally, the risk factors obtained from the multivariate regression analysis were used to establish the nomogram model. The validation of the nomogram was assessed by the concordance index (C-index), the receiver operating characteristic (ROC) curve, decision curve analysis (DCA), and calibration curves. Results A total of 820 patients were included in the present study for evaluation. Multivariate logistic regression analysis demonstrated that low preoperative hemoglobin (Hb), general anesthesia (GA), non-use of tranexamic acid (TXA), and older age were independent risk factors for blood transfusion after hip fracture operation. The C-index of this model was 0.86 (95% CI, 0.83–0.89). Internal validation proved the nomogram model’s adequacy and accuracy, and the results showed that the predicted value agreed well with the actual values. Conclusions A nomogram model was developed based on independent risk factors for blood transfusion after hip fracture surgery. Preoperative intervention can effectively reduce the incidence of blood transfusion after hip fracture operations.

Abstract Background Postoperative ischemic stroke is a devastating complication following total hip arthroplasty (THA). The purpose of the current study was to investigate the incidence of postoperative acute ischemic stroke (AIS) in patients ≥70 years old with THA for hip fracture after 90 days and independent risk factors associated with 90-day AIS. Methods A multicenter retrospective study was conducted, patients ≥70 years old with THA for hip fracture under general anesthesia were included from February 2017 to March 2020. Patients with AIS within 90 days after THA were identified as AIS group; patients with no AIS were identified as no AIS group. The baseline characteristics and risk factors were collected, multivariable logistic regression was used to identify independent risk factors of 90-dayAIS. Results: 2517 patients (mean age 76.18 ± 6.01) were eligible for inclusion in the study. 2.50% (63/2517) of patients had 90-day AIS. Compared with no AIS, older age, diabetes, hyperlipidemia, atrial fibrillation (AF) and higher D-dimer value were more likely in patients with AIS (P < 0.05), and anticoagulant use was fewer in patients with AIS. ROC curve analysis showed that the optimal cut point of D-dimer for AIS was D-dimer≥4.12 μg/ml. Multivariate logistic regression analysis showed that D-dimer≥4.12 μg/ml [adjusted odds ratio (aOR), 4.44; confidence interval (CI), 2.50–7.72; P < 0.001], older age (aOR, 1.08; 95%CI, 1.03–1.12; P < 0.001), hyperlipidemia (aOR, 2.28; 95%CI, 1.25–4.16; P = 0.007), atrial fibrillation (aOR, 5.84; 95% CI, 1.08–15.68; P = 0.001), and diabetes (aOR, 2.60; 95% CI, 1.56–4.39; P < 0.001) were associated with increased risk of 90-day AIS after THA. Conclusions In conclusion, we found that the incidence of 90-day AIS in patients≥70 years old with THA for hip fracture was 2.5%. Older age, diabetes, hyperlipidemia, AF and higher D-dimer value were independent risk factors for 90-day AIS in patients≥70 years old with THA for hip fracture.

Abstract Objective: Large sample investigations for risk factors for pneumonia in elderly patients after hip fracture surgeries are lacking. The purpose of this study is to determine the incidence and risk factors for postoperative pneumonia in geriatric patients following hip fracture operations.Methods: A retrospective study of incidence and risk factors in a tertiary referral center between 2016 and 2020 was conducted. Geriatric patients who developed postoperative pneumonia after surgeries of hip fracture during hospitalization stay were defined as cases and those without as controls. Multivariate logistic regression model was used to evaluate risk factors for postoperative pneumonia.Results: This study included 3147 patients, and 182 developed postoperative pneumonia, denoting the rate of 5.7%. In the multivariate analyses, age (OR, 1.04; 95% CI, 1.02–1.06), sex (males) (OR, 2.27; 95% CI, 1.64-3.13), respiratory disease (OR, 3.74; 95% CI, 2.32–6.04), heart disease (OR, 1.68; 95% CI, 1.14–2.47), cerebrovascular disease (OR, 1.58; 95% CI, 1.11–2.27), liver disease (OR, 2.61; 95% CI, 1.33–5.15), preoperative stay (OR, 1.08; 95% CI, 1.05–1.11) and general anesthesia (OR, 1.61; 95% CI, 1.15-2.27) were identified as independent risk factors for postoperative pneumonia.Conclusions: This study identified several risk factors for pneumonia in geriatric patients after hip fracture operations, providing a viable preventive strategy for optimizing clinical conditions for reductionof postoperative pneumonia.
