Anticoagulation Use prior to Common Dental Procedures: A Systematic Review. Currently, the number of patients on oral anticoagulation is increasing. There is a paucity of data regarding maintaining oral anticoagulation (especially novel oral anticoagulants) around the time of specific dental procedures. A dentist has three options: either to stop anticoagulation, to continue it, or to bridge with heparin. A systematic review of 10 clinical trials was conducted to address this issue (...) . It was found that continuing anticoagulation during dental procedures did not increase the risk of bleeding in most trials. Although none of the studies reported a thromboembolic event after interruption of anticoagulation, the follow-up periods were short and inconsistent, and the heightened thromboembolic risk when stopping anticoagulation is well known in the literature. Heparin bridging was associated with an increased bleeding incidence. We recommend maintaining oral anticoagulation with vitamin K
Calibrated Automated Thrombinography (CAT), a Tool to Identify Patients at Risk of Bleeding during Anticoagulant Therapy: A Systematic Review. Background Bleeding is a feared adverse event during anticoagulant treatment. In patients on vitamin K antagonists, most bleedings occur with the international normalized ratio (INR) in the therapeutic range. Currently, identification of high-risk patients via laboratory methods is not reliable. In this systematic review, we assessed the ability (...) of calibrated automated thrombin generation (CAT-TG) to predict bleeding in patients on anticoagulant treatment. Methods A systematic search was executed in three databases: Medline, Embase, and Cochrane. Results Seven studies were included; two were of good methodological quality. One study showed that patients on warfarin with INRs in range (2-3) admitted for hemorrhage ( n = 28), had lower CAT-TG levels (endogenous thrombin potential [ETP]: 333 ± 89 nM/min) than patients on warfarin admitted for other
Direct oral anticoagulants for treatment of deep vein thrombosis: overview of systematic reviews. A number of limitations of standard therapy with warfarin for deep vein thrombosis (DVT) have been established. This overview of systematic reviews presents the baseline results for efficacy and safety of the new direct oral anticoagulants (DOACs) thrombin inhibitors, and activated factor X (Xa) inhibitors in patients with DVT. Searches were run on PubMed and the Cochrane Database of Systematic
Anti-thrombotic therapy strategies with long-term anticoagulation after percutaneous coronary intervention - a systematic review and meta-analysis. Background: Long-term oral anticoagulants (OAC) increases bleeding risk after the percutaneous coronary intervention (PCI) with dual antiplatelet therapy (DAPT) with Aspirin and P2Y12 inhibitors. We hypothesize that dual anti-thrombotic therapy (DATT) reduces bleeding without increased cardiovascular events. Objectives: DATT does not increase
The safe and risk assessment of perioperative antiplatelet and anticoagulation therapy in inguinal hernia repair, a systematic review. There is a lack of consensus on the continuation or cessation of perioperative antiplatelet and anticoagulation therapies in inguinal hernia repair, therefore, the local hospital protocols dealing with these agents vary. The aim of this study is to investigate the risk and safety of perioperative antiplatelet and anticoagulation therapies in patients undergoing (...) elective inguinal hernia repair.The major databases (PubMed, Embase, Springer, and Cochrane Library) were searched, and all studies published through January 2019 were identified, using the keywords Aspirin, Clopidogrel, Warfarin, antiplatelet, anticoagulation, inguinal hernia repair, bleeding, hematoma, complications. All relevant articles and reference lists in these original studies were also obtained from the above databases.Thirteen articles were identified, ten studies reported the results
Comparison of the New Oral Anticoagulants and Warfarin in Patients with Atrial Fibrillation and Valvular Heart Disease: Systematic Review and Meta-Analysis. New oral anticoagulants (NOACs) are approved for use in nonvalvular atrial fibrillation (AF).This study aimed to evaluate the efficacy and safety of NOACs compared with warfarin in AF and valvular heart disease (VHD).We identified randomized controlled trials (RCTs) and post-hoc analyses comparing NOACs and warfarin in AF and VHD, including
Efficacy and safety of direct oral anticoagulants versus low-molecular-weight heparin in patients with cancer: a systematic review and meta-analysis. The efficacy and safety of direct oral anticoagulants (DOACs) versus low-molecular-weight heparin (LMWH) are still debated in the treatment of patients with cancer, and the optimal duration of therapy remains uncertain. Electronic databases (PubMed, Embase, and Cochrane Library) were searched to retrieve studies on the efficacy and safety of DOACs (...) . Patients with cancer who received DOACs exhibited a significant reduction in recurrent VTE with no increased risk of major bleeding compared with LMWH. DOACs may be an alternative choice for long-term anticoagulant therapy in patients with cancer.
Elderly Bleeding Risk of Direct Oral Anticoagulants in Nonvalvular Atrial Fibrillation: A Systematic Review and Meta-Analysis of Cohort Studies. The 2014 American Heart Association (AHA)/American College of Cardiology (ACC)/Heart Rhythm Society (HRS) guidelines recommend anticoagulation to reduce clot formation and the risk of thromboembolic events in patients with atrial fibrillation but does not specify guidelines for the elderly population. Direct oral anticoagulants (DOACs) are newer US FDA
Meta-analysis of real-world evidence comparing non-vitamin K antagonist oral anticoagulants with vitamin K antagonists for the treatment of patients with non-valvular atrial fibrillation. Introduction: Numerous real-world studies have compared non-vitamin K antagonist oral anticoagulants (NOACs) with vitamin K antagonists (VKAs) in patients with non-valvular atrial fibrillation (NVAF). A meta-analysis was performed to synthesize the available evidence. Methods: Systematic searches were
Does Anticoagulation Improve Flap Outcomes in Hypercoagulable Patients? A Systematic Review. Despite improvements in microsurgical techniques, hypercoagulable patients remain a reconstructive challenge. Thrombophilias are a relatively common problem with potentially catastrophic results including free flap loss. The aim of this study was to assess the available literature on free tissue transfer in patients with known hypercoagulability to develop recommendations for management. A systematic (...) review of the PubMed, EBSCO, and Cochrane databases was performed in June 2018. Inclusion criteria were assessment of outcomes of free tissue transfer in patients with established hypercoagulability. Exclusion criteria were review articles, case reports, and studies lacking detailed discussion of anticoagulation regimens and surgical outcomes. Data collected included the number of hypercoagulable patients, anticoagulation regimens, thrombotic complications, flap success, and bleeding complications
Anticoagulation for the Treatment of Cancer-Associated Thrombosis: A Systematic Review and Network Meta-Analysis of Randomized Trials. To perform a systematic review and network meta-analysis evaluating the efficacy and safety of low-molecular-weight heparins (LMWHs), vitamin K antagonists (VKAs), and direct-acting oral anticoagulants (DOACs) for the treatment of cancer-associated thrombosis (CAT). We searched MEDLINE, Cochrane Central Register of Controlled Trials, and conference abstracts (...) through March 2018. Randomized controlled trials (RCTs) enrolling adults with CAT comparing 2 or more full-dose anticoagulants (LMWH, VKA, and DOAC) and evaluating recurrent venous thromboembolism (VTE), major bleeding, and/or all-cause mortality were included. Reviewers identified studies, extracted data, and assessed the quality of the evidence in duplicate. A frequentist network meta-analysis, which uses direct and indirect evidence to simultaneously compare multiple interventions, was performed
The Reversal of Bleeding Caused by New Oral Anticoagulants (NOACs): A Systematic Review and Meta-Analysis. New oral anticoagulants (NOACs; ie, direct thrombin inhibitor [DTI] and factor Xa [FXa] inhibitors) were used as alternatives to warfarin. Specific antidotes (idarucizumab for dabigatran and andexanet alfa for FXa inhibitors) and hemostatic reversal agents were used for lowering bleeding, but their efficacies were still uncertain. The objectives of this study were to estimate and compare
Anticoagulant chemoprophylaxis in patients with traumatic brain injuries: A systematic review. Traumatic brain injury (TBI) continues to be a deadly injury. Universally accepted guidelines regarding the use of venous thromboembolism (VTE) chemoprophylaxis in trauma patients presenting with TBI have not been established. The purpose of this review was to identify and review the current literature and present the evidence for anticoagulant chemoprophylaxis regimens in patients with TBI.A search
A systematic review on the effects of direct oral anticoagulants on cancer growth and metastasis in animal models. Direct oral anticoagulants (DOACs) are now the first choice thromboprophylaxis in cancer patients who do not have a high risk of bleeding. In addition to the anticoagulant effects, potential anti-tumor effects of DOACs have also been studied in animal cancer models. In this study, we summarize the effects of DOACs on cancer growth and metastasis in animal models through
Do computerized clinical decision support systems improve the prescribing of oral anticoagulants? A systematic review. Serious adverse drug reactions have been associated with the underuse or the misuse of oral anticoagulant therapy. We systematically reviewed the impact of computerized clinical decision support systems (CDSS) on the prescribing of oral anticoagulants and we described CDSS features associated with success or failure.We searched Medline, Embase, CENTRAL, CINHAL, and PsycINFO (...) for studies that compared CDSS for the initiation or monitoring of oral anticoagulants with routine care. Two reviewers performed study selection, data collection, and risk-of-bias assessment. Disagreements were resolved with a third reviewer. Potentially important CDSS features, identified from previous literature, were evaluated.Sixteen studies were included in our qualitative synthesis. Most trials were performed in primary care (n = 7) or hospitals (n = 6) and included atrial fibrillation (AF
Prevention of venous thromboembolism in patients with cancer with direct oral anticoagulants: A systematic review and meta-analysis. Patients with cancer are of a high level risk of venous thromboembolism (VTE). Low molecular weight heparin (LMWH) is recommended as the normal treatment for cancer-associated venous thrombosis. Recently, some studies suggest that patients with cancer-associated venous thrombosis can get a good efficacy and safety profile from treating with direct oral (...) anticoagulants (DOACs) compared with other anticoagulants. However, when it comes to the efficacy of DAOCs in preventing VTE in patient with cancer, the data are limited. Thus, we performed such a meta-analysis to determine the efficacy and safety of DOACs in preventing VTE in patient with cancer compared with LMWHs.Medline/PubMed and CENTRAL (The Cochrane Central Register of Controlled Trials) were systematically searched for relevant studies. For each trial, data on VTE, major bleeding, or bleeding were
Risk of major bleeding during extended oral anticoagulation in patients with first unprovoked venous thromboembolism: a systematic review and meta-analysis protocol. The optimal duration of anticoagulation after a first unprovoked venous thromboembolism (VTE) remains controversial. Deciding to stop or continue anticoagulant therapy indefinitely after completing 3 to 6 months of initial treatment requires balancing the long-term risk of recurrent VTE if anticoagulation is stopped against (...) the long-term risk of major bleeding if anticoagulation is continued. However, knowledge of the long-term risk for major bleeding events during extended anticoagulation in this patient population is limited. We plan to conduct a systematic review and meta-analysis to quantify the risk for major bleeding events during extended oral anticoagulation in patients with first unprovoked VTE.Electronic databases including MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials
A meta-analysis of bridging anticoagulation between low molecular weight heparin and heparin. Patients with mechanical heart valves (MHV) have an increased risk of thromboembolic complications. Low molecular weight heparin (LMWH) and unfractionated heparin (UFH) are often recommended for bridging anticoagulation; however, it is not clear which strategy is more beneficial.The PubMed, EMBASE, and Cochrane databases were searched from January 1960 to March 2019. Randomized controlled trials (...) the difference was not statistically significant.Our meta-analysis suggests that LMWH not only reduces the risk of thromboembolism in patients with MHV but also does not increase the risk of major bleeding. LMWH may provide safer and more effective bridging anticoagulation than UFH in patients with MHV. It is still necessary to conduct future randomized studies to verify this conclusion.
A meta-analysis on anticoagulation after vascular trauma. There is much debate regarding the use of anticoagulation following vascular trauma. The aim of this meta-analysis was to compare the outcome of trauma following administration of anticoagulation medication.The literature search was carried out using Ovid MEDLINE and PubMed databases to search for keywords and MeSH terms including "Anticoagulation", "Vascular Surgery", "Vascular Trauma", "Vascular Repair", "Repair" and "Wounds (...) and Injuries".Use of anticoagulation was associated with a better prognosis for overall vascular trauma outcomes (weighted OR 0.46; 95% CI 0.34-0.64; P < 0.00001), as well as reduced risk of amputation for both lower and upper limb vascular trauma (weighted OR 0.42; 95% CI 0.22-0.78; P = 0.007), and reduced occurrence of reoperation events and amputations in isolated lower limb vascular trauma (weighted OR 0.27; 95% CI 0.14-0.52; P < 0.0001).There was a statistically significant correlation between the use
