Abstract
Venous thromboembolism (VTE) encompasses deep vein thrombosis and pulmonary embolism, both of which can present on a spectrum from subtle symptoms to life- and limb-threatening emergencies. Some risk factors for VTE overlap cardiovascular risk factors and statin therapy can somewhat reduce the VTE risk. When presentations are not life-threatening, clinical prediction scores using the Well's criteria are best used to determine diagnostic testing. The mainstay of VTE treatment is anticoagulant therapy, although life- and limb-threatening presentations can also require thrombolytic therapy.

Using machine learning in the prediction of symptomatic venous thromboembolism following ankle fracture. Foot Ankle Surg 2024; 30:110-116. [PMID: 38193887 DOI: 10.1016/j.fas.2023.10.003] [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: 07/05/2023] [Revised: 08/31/2023] [Accepted: 10/13/2023] [Indexed: 01/10/2024]
Abstract
BACKGROUND Venous thromboembolism (VTE) is a major cause of morbidity and mortality in the trauma setting, and both prediction and prevention of VTE have long been a concern for healthcare providers in orthopedic surgery. The purpose of this study was to evaluate the use of novel statistical analysis and machine-learning in predicting the risk of VTE and the usefulness of prophylaxis following ankle fractures. METHODS The medical profiles of 16,421 patients with ankle fractures were screened retrospectively for symptomatic VTE. In total, 238 patients sustaining either surgical or nonsurgical treatment for ankle fracture with subsequently confirmed VTE within 180 days following the injury were placed in the case group. Alternatively, 937 patients who sustained ankle fractures managed similarly but had no documented evidence of VTE were randomly chosen as the control group. Individuals from both the case and control populations were also divided into those who had received VTE prophylaxis and those who had not. Over 110 variables were included. Conventional statistics and machine learning methods were used for data analysis. RESULTS Patients who had a motor vehicle accident, surgical treatment, increased hospital stay, and were on warfarin were shown to have a higher incidence of VTE, whereas patients who were on statins had a lower incidence of VTE. The highest Area Under the Receiver Operating Characteristic Curves (AUROC) showing the performance of our machine learning approach was 0.88 with 0.94 sensitivity and 0.36 specificity. The most balanced performance was seen in a model that was trained using selected variables with 0.86 AUROC, 0.75 sensitivity, and 0.85 specificity. CONCLUSION By using machine learning, this study successfully pinpointed several predictive factors linked to the occurrence or absence of VTE in patients who experienced an ankle fracture. Training these algorithms using larger, more granular, and multicentric data will further increase their validity and reliability and should be considered the standard for the development of such algorithms. LEVEL OF EVIDENCE Case-Control study - 3.

Accelerated fixation is associated with fewer pulmonary embolism in patients with isolated and unilateral femoral shaft fractures: A TQIP analysis. Injury 2023; 54:111010. [PMID: 37729812 DOI: 10.1016/j.injury.2023.111010] [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: 06/01/2023] [Revised: 07/29/2023] [Accepted: 08/28/2023] [Indexed: 09/22/2023]
Abstract
INTRODUCTION The optimal time to intramedullary internal fixation for patients with isolated and unilateral femoral shaft fractures was investigated by the American College of Surgeons-Trauma Quality Improvement Program (ACS-TQIP). MATERIAL AND METHODS Adult patients from the TQIP between 2017 and 2019 were eligible for inclusion. The associations between time to fixation and target outcomes (pulmonary embolism [PE], deep vein thrombosis [DVT], acute respiratory distress syndrome [ARDS], and mortality) were assessed. Maximization of the sum of sensitivity and specificity was used to determine the optimal cut point. The patients were divided into three groups according to different time to fixation intervals. A multinomial propensity scores weighting using generalized boosted models was performed for all unbiased pre-treatment factors between the groups. Multivariate logistic regression was used to clarify the outcomes predictors. RESULTS The univariate and multivariate analysis before weighting showed that only PE was significantly associated with time to fixation (odds ratio [OR], 1.05; 95% confidence interval [CI], 1.01-1.09; p = 0.012). The optimal cut point of time to fixation was 13.88 h. The patients were divided into accelerated (≤ 13.88 h), standard (> 13.88 and ≤ 24 h), and delayed (> 24 and < 36 h) groups. After weighting for all unbiased pre-treatment factors between the groups, multivariate logistic regression showed that standard group significantly increased the risk of PE compared with accelerated group (OR, 4.436; 95% CI, 1.844-10.672; p = 0.001). CONCLUSION Accelerated intramedullary internal fixation within 13.88 h was associated with a significantly decreased risk of PE compared with standard fixation in patients with isolated and unilateral femoral shaft fractures without additional mortality risks.

Longitudinal D-Dimer Trajectories and the Risk of Mortality in Abdominal Trauma Patients: A Group-Based Trajectory Modeling Analysis. J Clin Med 2023; 12:jcm12031091. [PMID: 36769738 PMCID: PMC9917395 DOI: 10.3390/jcm12031091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Revised: 01/03/2023] [Accepted: 01/28/2023] [Indexed: 01/31/2023] Open
Abstract
This study aimed to identify the long-term D-dimer trajectory patterns and their associations with in-hospital all-cause mortality in abdominal trauma patients. This is a retrospective cohort study of general adult abdominal trauma patients admitted to Jinling Hospital (Nanjing, China) between January 2010 and April 2020. Group-based trajectory modeling was applied to model D-dimer trajectories over the first 50 days post-trauma. A multivariable logistic regression was performed to estimate the associations between D-dimer trajectories and in-hospital all-cause mortality. A total of 309 patients were included. We identified four distinct D-dimer trajectories: group 1 (57.61%; "stable low"), group 2 (28.16%; "moderate-decline"), group 3 (8.41%; "high-rapid decline"), and group 4 (5.83%; "high-gradual decline"). The SOFA score (p = 0.005) and ISS (p = 0.001) were statistically higher in groups 3 and 4 than in groups 1 and 2. The LMWH and UFH did not differ between groups 3 and 4. Compared with the patients in group 1, only the patients in group 4 were at a higher risk of in-hospital all-cause mortality (OR = 6.94, 95% CI: 1.20-40.25). The long-term D-dimer trajectories post-trauma were heterogeneous and associated with mortality. An initially high and slowly-resolved D-dimer might function as the marker of disease deterioration, and specific interventions are needed.

Age-dependent thrombin generation predicts 30-day mortality and symptomatic thromboembolism after multiple trauma. Sci Rep 2023; 13:1681.

Abstract
Trauma-induced coagulopathy (TIC) is a risk factor for death and is associated with deviations in thrombin generation. TIC prevalence and thrombin levels increase with age. We assayed in vivo and ex vivo thrombin generation in injured patients (n = 418) to specifically investigate how age impacts thrombin generation in trauma and to address the prognostic ability of thrombin generation. Biomarkers of thrombin generation were elevated in young (< 40 years) and older (≥ 40 years) trauma patients. In vivo thrombin generation was associated with Injury Severity Score (ISS) and this association was stronger in young than older patients. In vivo thrombin generation decreased faster after trauma in the young than the older patients. Across age groups, in vivo thrombin generation separated patients dying/surviving within 30 days at a level comparable to the ISS score (AUC 0.80 vs. 0.82, p > 0.76). In vivo and ex vivo thrombin generation also predicted development of thromboembolic events within the first 30 days after the trauma (AUC 0.70-0.84). In conclusion, younger trauma patients mount a stronger and more dynamic in vivo thrombin response than older patients. Across age groups, in vivo thrombin generation has a strong ability to predict death and/or thromboembolic events 30 days after injury.

Abstract
Venous thromboembolism (VTE), which encompasses deep venous thrombosis (DVT) and pulmonary embolism (PE), is a major public health concern due to its high incidences of morbidity and mortality. Patients who have experienced trauma with prolonged immobilization are at an increased risk of developing VTE. Plasma D-dimer levels have been known to be elevated in trauma patients, and they were closely correlated with the number of fractures. In other words, plasma D-dimer levels cannot be used as the only indicator of VTE in trauma cases. Given the limitations, further study is needed to explore other potential biomarkers for diagnosing VTE. To date, various established and novel VTE biomarkers have been studied in terms of their potential for predicting VTE, diagnostic performance, and improving clinical therapy for VTE. Therefore, this review aims to provide information regarding classic and essential haemostasis (including prothrombin time (PT), activated partial thromboplastin time (aPTT), D-dimer, fibrinogen, thrombin generation, protein C, protein S, antithrombin, tissue factor pathway inhibitor, and platelet count) and inflammatory biomarkers (C-reactive protein, erythrocyte sedimentation rate, and soluble P-selectin) as potential diagnostic biomarkers that can predict the risk of VTE development among trauma patients with prolonged immobilization. Thus, further advancement in risk stratification using these biomarkers would allow for a better diagnosis of patients with VTE, especially in areas with limited resources.

Abstract
INTRODUCTION Orthopaedic trauma patients are at high risk of venous thromboembolism (VTE). As VTE prophylaxis has gradually raised public concerns, guidelines related to this topic have increased over time. However, the existing recommendations of thromboprophylaxis guidelines in orthopaedic trauma patients are still inconsistent, and the quality of the guidelines and recommendations for the topic still lacks comprehensive assessments. This review aims to critically appraise clinical practice guidelines for thromboprophylaxis in orthopaedic trauma patients. METHODS AND ANALYSIS We will conduct a comprehensive literature search up to 31 October 2022 in databases (PubMed, EMBASE, CINAHL, Web of Science, the Cochrane Library, etc), academic websites and guideline repositories. The quality of the guidelines and recommendations will be assessed by five reviewers independently using the Appraisal of Guidelines Research and Evaluation II instrument (AGREE-II) and the AGREE - Recommendation EXcellence (AGREE-REX). We will summarise the characteristics of the guidelines and compare the differences between these recommendations. ETHICS AND DISSEMINATION This study will follow the Declaration of Helsinki and has received approval from the Ethics Committee on Biomedical Research, West China Hospital, Sichuan University (ethics approval no. 2021-989). The results will be summarised as a paper, disseminated through peer-reviewed journals, and will help guide further research in the future. PROTOCOL REGISTRATION NUMBER CRD42021273405.

Abstract
OBJECTIVE Venous thromboembolism (VTE) is a life threating complication in intensive care units (ICUs). This study aimed to pool the prevalence of VTE and examined the risk factors of VTE in intensive care patients worldwide. METHODS A systematic search in PubMed, EMBASE and Web of Science databases was performed. Studies reported that the data on the prevalence of VTE or relevant information were synthesized using a random-effects model. RESULTS A total of 42 studies reporting on 27,344 patients were included. The pooled prevalence of VTE was 10.0% (95% CI: 7.0-14.0%). Subgroup and metaregression analyses found that thromboprophylaxis strategy, simplified acute physiology score (SAPS II), age, study quality, sample size, malignancy, sex, spinal cord injury and injury severity score (ISS) moderated the prevalence of VTE in intensive care patients. CONCLUSIONS The present meta-analysis revealed a high prevalence of VTE in critically ill patients. The risk factors of VTE included thromboprophylaxis strategy, SAPS II, age, malignancy, sex, spinal cord injury and ISS. Therefore, we need to pay more attention to high-risk populations of VTE in intensive care patients.

Abstract
BACKGROUND Posttraumatic venous thromboembolism (VTE) remains prevalent in severely injured patients despite chemoprophylaxis. Importantly, although platelets are central to thrombosis, they are not routinely targeted in prevention of posttraumatic VTE. Furthermore, platelets from injured patients show ex vivo evidence of increased activation yet impaired aggregation, consistent with functional exhaustion. However, the relationship of this platelet functional phenotype with development of posttraumatic VTE is unknown. We hypothesized that, following injury, impaired ex vivo platelet aggregation (PA) is associated with the development of posttraumatic VTE. METHODS We performed a secondary analysis of 133 severely injured patients from a prospective observational study investigating coagulation and inflammation (2011-2019). Platelet aggregation in response to stimulation with adenosine diphosphate (ADP), collagen, and thrombin was measured at presentation (preresuscitation) and 24 hours (postresuscitation). Viscoelastic clot strength and lysis were measured in parallel by thromboelastography. Multivariable regression examined relationships between PA at presentation, 24 hours, and the change (δ) in PA between presentation and 24 hours with development of VTE. RESULTS The 133 patients were severely injured (median Injury Severity Score, 25), and 14% developed VTE (all >48 hours after admission). At presentation, platelet count and PA were not significantly different between those with and without incident VTE. However, at 24 hours, those who subsequently developed VTE had significantly lower platelet counts (126 × 10 9 /L vs. 164 × 10 9 /L, p = 0.01) and lower PA in response to ADP ( p < 0.05), collagen ( p < 0.05), and thrombin ( p = 0.06). Importantly, the magnitude of decrease in PA (δ) from presentation to 24 hours was independently associated with development of VTE (adjusted odds ratios per 10 aggregation unit decrease: δ-ADP, 1.31 [ p = 0.03]; δ-collagen, 1.36 [ p = 0.01]; δ-thrombin, 1.41 [ p < 0.01]). CONCLUSION Severely injured patients with decreasing ex vivo measures of PA despite resuscitation have an increased risk of developing VTE. This may have implications for predicting development of VTE and for studying platelet targeted chemoprophylaxis regimens. LEVEL OF EVIDENCE Prognostic/Epidemiological; Level III.

Abstract
Purpose: The aim of this study was to investigate the epidemiology of trauma inpatients with venous thromboembolism (VTE) symptoms diagnosed using computed tomographic angiography (CTA) in KoreaMethods: In total, 7,634 patients admitted to the emergency department of Gachon University Gil Medical Center, a tertiary hospital, and hospitalized between July 1, 2018 and December 31, 2020 were registered for this study. Of these patients, 278 patients who underwent CTA were enrolled in our study. Results: VTE was found in 120 of the 7,634 patients (1.57%), and the positive diagnosis rate of the 278 patients who underwent CTA was 43.2% (120 of 278). The incidence of VTE was statistically significantly higher among those with severe head and neck injuries (Abbreviated Injury Scale, 3–5) than among those with nonsevere head and neck injuries (Abbreviated Injury Scale, 0–2; P=0.038). In a subgroup analysis, the severe and nonsevere head and neck injury groups showed statistically significant differences in known independent risk factors for VTE. In logistic regression analysis, the adjusted odds ratio of severe head and neck injury (Abbreviated Injury Scale, 3–5) for VTE was 1.891 (95% confidence interval, 1.043–3.430). Conclusions: Trauma patients with severe head and neck injuries are more susceptible to VTE than those with nonsevere head and neck injuries. Thus, physicians must consider CTA as a priority for the diagnosis of VTE in trauma patients with severe head and neck injuries who show VTE-associated symptoms.

Abstract
BACKGROUND Venous thromboembolism (VTE) in severely injured patients with severe traumatic brain injury (TBI) is a risk during the clinical course. Data on the safety of an early initiation of pharmacological VTE prophylaxis in severely injured patients with concomitant severe TBI is sparse. METHODS Admissions to our level-1-trauma center between January 2015 and December 2018 were screened. Patients suffering from severe TBI (Abbreviated Injury Scale (AIS) of the head ≥3) and at least one further AIS ≥ 3 in any other body region were included. Demographic data, thromboembolic events, and progression of the intracranial hemorrhage were extracted from the patient's charts. According to the first application of pharmacological thromboprophylaxis (VTEp), patients were categorized either to the early, the late (later than 24 h) or the no therapy group. RESULTS In 79 patients (early: n = 35, late: n = 29, no therapy: n = 15) the Injury Severity Score (ISS) was 36.7 ± 12.7 points (AIShead 4.1 ± 0.8). No differences were found regarding the progression of the intracranial hemorrhage after initiation of the VTE prophylaxis (adj. p = 0.8). The VTE rate was low (n = 1, 1.6%). CONCLUSION In severely injured patients with severe TBI, the early administration of pharmacological thromboprophylaxis did not result in a higher rate of intracranial hematoma progression.

Abstract
D-dimer level is often used to assess the severity of trauma as well as the risk of thrombosis. This study investigated the risk factors for high postoperative D-dimer level. This study included a total of 2706 patients undergoing breast cancer surgery to examine the associations between various clinicopathological factors and variation in D-dimer levels. After adjusting for other factors, T stage, neoadjuvant chemotherapy, blood loss, surgery type, diabetes, and elevated leukocyte and neutrophil counts were found to be significant risk factors for D-dimer variation. This study identified several factors associated with elevated D-dimer levels and consequent thrombosis after breast cancer surgery, which may aid in the development of more precise preventive measures and interventions as well as serve as a reference for future research.

Chemoprophylaxis for venous thromboembolism in pelvic and/or acetabular fractures: A systematic review. Injury 2022; 53:1449-1454. [PMID: 35148902 DOI: 10.1016/j.injury.2022.01.045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 01/24/2022] [Accepted: 01/29/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND It is unclear which pharmacological agents, and at what dosage and timing, are most effective for venous thromboembolism (VTE) prophylaxis in patients with pelvic/acetabular fractures. METHODS We searched the Cochrane Database of Systematic Reviews, Embase, Web of Science, EBSCO, and PubMed on October 3, 2020, for English-language studies of VTE prophylaxis in patients with pelvic/acetabular fractures. We applied no date limits. We included studies that compared efficacy of pharmacological agents for VTE prophylaxis, timing of administration of such agents, and/or dosage of such agents. We recorded interventions, sample sizes, and VTE incidence, including deep vein thrombosis (DVT) and pulmonary embolism. RESULTS Two studies (3604 patients) compared pharmacological agents, reporting that patients who received direct oral anticoagulants (DOACs) were less likely to develop DVT than those who received low molecular weight heparin (LMWH) (p < 0.01). Compared with unfractionated heparin (UH), LMWH was associated with lower odds of VTE (odds ratio [OR] = 0.37, 95% confidence interval [CI]: 0.22-0.63) and death (OR = 0.27, 95% CI: 0.10-0.72). Three studies (3107 patients) compared timing of VTE prophylaxis, reporting that late prophylaxis was associated with higher odds of VTE (OR = 1.9, 95% CI: 1.2-3.2) and death (OR = 4.0, 95% CI: 1.5-11) and higher rates of symptomatic DVT (9.2% vs. 2.5%, p = 0.03; and 22% vs. 3.1%, p = 0.01). One study (31 patients) investigated dosage of VTE prophylaxis, reporting that a higher proportion of patients with acetabular fractures were underdosed (23% of patients below range of anti-Factor Xa [aFXa] had acetabular fractures vs. 4.8% of patients within adequate range of aFXa, p<0.01). CONCLUSIONS Early VTE chemoprophylaxis (within 24 or 48 h after injury) was better than late administration in terms of VTE and death. Many patients with acetabular fractures are underdosed with LMWH, with inadequate aFXa levels. Compared with UH, LMWH was associated with lower odds of VTE and death. DOACs were associated with lower risk of DVT compared with LMWH. LEVEL OF EVIDENCE III, systematic review of retrospective cohort studies.

Abstract
BACKGROUND We aimed to identify risk factors and risk scoring models to help identify post-traumatic pulmonary embolisms (PE). METHODS We performed a retrospective review (2014-2019) of all adult trauma patients admitted to our Level I trauma center that received a CT pulmonary angiogram (CTPA) for a suspected PE. A systematic literature search found eleven risk scoring models, all of which were applied to these patients. Scores of patients with and without PE were compared. RESULTS Of the 235 trauma patients that received CTPA, 31 (13%) showed a PE. No risk scoring model had both a sensitivity and specificity above 90%. The Wells Score had the highest area under the curve (0.65). After logistic regression, no risk scoring model variables were independently associated with PE. CONCLUSIONS In trauma patients with clinically suspected PE, clinical variables and current risk scoring models do not adequately differentiate patients with and without PE.

Abstract
Background We aimed to assess the clinical characteristics, management practices, and inhospital outcomes of venous thromboembolism (VTE) among trauma patients. Methods A retrospective analysis of all trauma patients with documented venous thromboembolic events in a level 1 trauma center was conducted. Patients were categorized into two groups based on the primary initial presentation postinjury (deep-vein thrombosis [DVT] or pulmonary embolism [PE]). Results Across the study period, a total of 662 patients were confirmed to have DVT and 258 patients were diagnosed with acute PE. Among them, 84 patients were identified to have trauma-associated VTE; 56 (8.5%) had DVT and 28 (10.9%) had PE. Two patients who initially presented with DVT developed PE on follow-up. There were 38 females and 46 males with a mean age of 46 ± 18 years. Abnormal coagulation profile was reported as 7 protein C deficiencies, 5 protein S deficiencies, 6 homocystinemia, 4 antithrombin III deficiency, 4 lupus anticoagulant, and 2 Factor V Leiden. Age, sex, obesity, D-dimer level, and treatment (except for heparin) were comparable between the two groups; whereas protein S deficiency, prior history of PE, bedridden status, congestive heart failure, and history of recent surgery, were more evident in the PE group. The incidence of postthrombotic syndrome was significantly higher in the DVT group. Overall mortality rate was 8.3% (DVT; 8.9% vs. PE; 7.1%, respectively = 0.78). Conclusion Coagulation profile plays an important role in posttraumatic thromboembolic disease. A thorough assessment for features of thromboembolic disorders is warranted in polytrauma patients to avoid missing this potentially life-threatening diagnosis. Larger studies are needed for better understanding and management of VTE in trauma.

Does preoperative pharmacologic prophylaxis reduce the rate of venous thromboembolism in pancreatectomy patients? HPB (Oxford) 2020; 22:1020-1024. [PMID: 31732463 DOI: 10.1016/j.hpb.2019.10.2437] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2019] [Revised: 10/05/2019] [Accepted: 10/16/2019] [Indexed: 12/12/2022]
Abstract
BACKGROUND Whether the risk of venous thromboembolism (VTE) may be reduced by preoperative administration of prophylactic heparin is unknown. We hypothesized that timing of heparin administration does not significantly alter the incidence of VTE in pancreatic surgery. METHODS An analysis was conducted using data from Massachusetts General Hospital's National Surgical Quality Improvement Program from 2012 to 2017. All patients admitted for elective pancreatic resection were included. The primary outcome was development of VTE. Multivariable regression was performed, adjusting for patient demographics and various clinical factors. RESULTS In total, 1448 patients were analyzed, of whom 1062 received preoperative heparin (73.3%). Overall, 36 (2.5%) patients developed VTE. On unadjusted analysis, there was no statistically significant difference between patients who received preoperative heparin compared with those who did not (2.6% vs. 1.3%, respectively; p = 0.079). On adjusted analysis, there was an association with increased VTE rates among patients who received preoperative heparin (OR 2.93, 95% CI 1.10-7.81; p = 0.031). CONCLUSION There was an association between preoperative heparin administration and increased incidence of VTE on adjusted analysis, possibly reflecting appropriate surgical judgment in patient selection for prophylaxis. These data question the inclusion of preoperative VTE pharmacologic prophylaxis as a reliable quality indicator.

Abstract
BACKGROUND As an elevated D-dimer level is directly proportional to the degrees of trauma and coagulation, it is often used to assess the severity of the trauma as well as the risk of thrombosis. This study aimed to investigate the risk factors for a high postoperative D-dimer level. METHODS A total of 623 patients undergoing radical mastectomy were included. The association between various clinicopathological factors and D-dimer variation was examined. RESULTS Age, neoadjuvant chemotherapy, diabetes, and elevated neutrophil count were significant risk factors for D-dimer variation, after adjusting for other factors. CONCLUSIONS This study has identified the characteristics of patients who are likely to experience considerable postoperative increases in the D-dimer level. The development of effective nursing interventions for these patients is the focus of future studies.

Abstract
Deep vein thrombosis (DVT) is a common complication after trauma. The development of markers to predict DVT in trauma patients is needed, and circulating microparticles (MPs) and their contents are possible candidates. In this study, we aimed to identify platelet factor 4 (PF4) and β-thromboglobulin (β-TG) mRNAs in circulating MPs as potential markers for DVT diagnosis in trauma patients. Fifteen trauma patients diagnosed with DVT and fifteen matched patients without DVT were included in this study. Fifteen healthy volunteers also were included as controls. Circulating MPs were obtained from the plasma of all study subjects. Annexin V+ MPs and platelet-derived MPs (PMPs) were quantified using flow cytometry. PF4 and β-TG mRNAs in MPs were determined by qPCR, and the common logarithm of relative quantitation (RQ) was calculated using the comparative Ct method. Receiver-operating characteristic (ROC) curves were performed to analyze the diagnostic value of PF4 and β-TG mRNAs. No significant differences were found in Annexin V+ MPs and PMPs levels between trauma patients with and without DVT. However, both PF4 and β-TG mRNAs in MPs from the DVT group were significantly higher than the non-DVT group and healthy controls (P = 0.014 for PF4, P = 0.010 for β-TG). The ROC curve analysis showed that both the PF4 mRNA (area-under curve (AUC) 0.756, P = 0.017) and the β-TG mRNA (AUC 0.751, P = 0.019) had a positive predictive value for DVT. This finding indicates that the PF4 and β-TG mRNAs in MPs may be used as potential biomarkers for DVT diagnosis in trauma patients.

Abstract
PURPOSE OF REVIEW Deep vein thrombosis (DVT) and pulmonary embolus are major causes of hospital-related morbidity and mortality, and are recognized as complications in patients with traumatic injury. Despite the significant morbidity and mortality associated with DVTs, prophylaxis and treatment are still not well understood and remain the subject of research and debate. RECENT FINDINGS Elements of the patient's history and physical examination, along with thromboelastography, can be used to predict patients who are at greatest risk of DVT and venous thromboembolism (VTE). Novel assays and biomarkers hold promise for more accurate evaluation of coagulation status. Patients with traumatic injury are routinely treated with either mechanical or pharmacological treatments to prevent DVT, and a growing body of evidence suggests that DVT prophylaxis should be initiated as early as possible in a patient's hospital course. SUMMARY In trauma patients with traumatic injury, early identification and targeted VTE prophylaxis in trauma patients may prevent this life-threatening complication.

Abstract
Our objective was to evaluate the efficacy and safety of natural hirudin and low molecular weight heparin (LMWH) in the prevention of perioperative deep venous thrombosis (DVT) in elderly patients with intertrochanteric fracture. From June 2014 to June 2017, 96 patients with intertrochanteric fractures were treated with proximal femoral nail antirotation (PFNA) were randomly divided into two groups. For DVT prevention, 45 patients were treated with oral natural hirudin and subcutaneous LMWH-calcium (test group) and 51 patients were treated with subcutaneous LMWH-calcium (control group). The mean intraoperative bleeding, wound drainage and incisional hematoma were higher in the test group, with no significant differences between the groups. There were significant differences in distal intramuscular venous thrombosis (P = 0.043). Both activated partial thromboplastin time (APTT), thrombin time (TT), and prothrombin time (PT) lengthened in both groups postoperatively, and there was a significant difference between the two groups two weeks postoperatively. D-dimer were significantly different and platelet count (PLT) did not differ between groups two weeks postoperatively. In elderly patients with unilateral intertrochanteric fracture after PFNA on anticoagulant therapy, the combination of natural hirudin and LMWH was more effective than that of LMWH-calcium alone, with no significant difference with regard to safety.
