Background: There is controversy over whether use of new oral anticoagulants (NOACs) associates with increased hemorrhage risk compared with non-NOAC. Meanwhile, determining which NOAC to use remains unclear. We aimed to summarize the evidence about NOACs in venous thromboembolism (VTE) prevention for patients with total hip and knee arthroplasty (THA and TKA).Methods: We searched RCTs assessing NOACs for VTE prophylaxis in adults undergoing THA and TKA in Medline, Embase, and Cochrane up to May 2021. Primary outcomes were VTE [included deep vein thrombosis (DVT) and pulmonary embolism (PE)], major VTE, and major bleeding. The rank probabilities of each treatment were summarized by the surface under the cumulative ranking curve area (SUCRA).Results: 25 RCTs with 42,994 patients were included. Compared with non-NOAC, NOACs were associated with a decreased risk of VTE (RR 0.68; 95% CI 0.55–0.84) and major VTE (RR = 0.52; 95% CI 0.35–0.76). Additionally, rivaroxaban, apixaban, and edoxaban but not dabigatran and betrixaban, did confer a higher efficacy compared with non-NOAC. None of the individual NOACs increased the risk of bleeding, while apixaban and betrixaban were even associated with a decreased risk of bleeding. In the comparison of different NOACs, rivaroxaban was associated with the greatest benefits in VTE (SUCRA = 79.6), DVT (SUCRA = 88.8), and major VTE (SUCRA = 89.9) prevention. Furthermore, subgroup analysis confirmed that NOACs associated with a higher efficacy tendency in patients with follow-up duration <60 days than follow-up duration ≥60 days.Conclusion: Evidence suggests that NOACs exert more benefits on VTE prophylaxis, and none of the individual NOACs increased hemorrhage compared with non-NOAC. Among various NOACs, rivaroxaban is recommended in patients with lower bleeding risk, and apixaban is recommended in patients with higher bleeding risk.Systematic Review Registration: [https://www.crd.york.ac.uk/prospero/], identifier [CRD42021266890].

Introduction. Current guidelines recommend dual antithrombotic therapy (DAT) for the majority of patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) and suggest a short course of triple antithrombotic therapy (TAT) for those at very high thrombotic risk (TR) but low bleeding risk (BR). Methods. We analyze if the PARIS ischemic-hemorrhagic scale could be useful for the choice of antithrombotic strategy in patients with acute coronary syndromes (ACS) and AF treated with coronary stenting enrolled in the prospective, observational, nationwide MATADOR-PCI study. Results. Among the 588 patients discharged alive, a TAT was prescribed in 381 (64.8%) and DAT in 52 (8.8%) patients. According to the PARIS scoring system, 142 (24.2%) were classified as low, 244 (41.5%) as intermediate and 292 (34.3%) as high TR. In parallel, 87 (14.8%) were categorized in the low, 260 (44.2%) in the intermediate and 241 (41.0%) in the high-risk stratum for major bleedings. Crossing the various strata of the two PARIS risk scores, the largest group of patients consisted of those at high TR and BR (n=130, 22%), followed by those at intermediate risk according to both scores (n=122, 21%). At discharge, TAT was mainly used in patients at intermediate to high BR, while DAT in those at intermediate to high TR but low BR, according to the PARIS score. Conclusion. Our data suggest that some variables associated with increased TR or BR are poorly considered in the daily practice while the use of PARIS scales could help in the implementation of guidelines' recommendations.

Abstract Background A balloon occlusion technique is suggested for use in cryobiopsy for interstitial lung diseases because of the bleeding risk. However, it may interfere with selection of the involved bronchus for peripheral pulmonary lesions (PPLs). A two-scope technique, in which two scopes are prepared and hemostasis is started using the second scope immediately after cryobiopsy, has also been reported. This study aimed to evaluate the safety and diagnostic utility of transbronchial cryobiopsy using the two-scope technique for PPLs. Methods Data of patients who underwent conventional biopsy followed by cryobiopsy using the two-scope technique for PPLs from November 2019 to March 2021 were collected. The incidence of complications and risk factors for clinically significant bleeding (moderate to life-threatening) were investigated. Diagnostic yields were also compared among conventional biopsy, cryobiopsy, and the combination of them. Results A total of 139 patients were analyzed. Moderate bleeding occurred in 25 (18.0%) patients without severe/life-threatening bleeding. Although five cases required transbronchial instillation of thrombin, all bleeding was completely controlled using the two-scope technique. Other complications included two pneumothoraces and one asthmatic attack. On multivariable analysis, only ground-glass features (P < 0.001, odds ratio: 9.30) were associated with clinically significant bleeding. The diagnostic yields of conventional biopsy and cryobiopsy were 76.3% and 81.3%, respectively (P = 0.28). The total diagnostic yield was 89.9%, significantly higher than conventional biopsy alone (P < 0.001). Conclusions The two-scope technique provides useful hemostasis for safe cryobiopsy for PPLs, with a careful decision needed for ground-glass lesions.

Abstract Background: Taking thrombosis and bleeding risks into consideration, little real world study data is available to dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in elderly Chinese chronic total occlusion (CTO) patients. Methods: We assigned 504 CTO patients aged ≥75 years who successfully underwent PCI from December 2009 to May 2020. The patients were randomized to Clopidogrel and Ticagrelor group and received DAPT for up to 12 months. Efficacy endpoints were evaluated by major adverse cardiac events (MACE) consisting of all-cause death, nonfatal myocardial infarction (MI) and clinically driven revascularization. The safety endpoints were recorded as the incidence of Bleeding Academic Research Consortium (BARC) bleeding. Results: Patients in Clopidogrel group were older, they had a higher percentage of BMI, diastolic blood pressure and HDL-C than those in Ticagrelor group. Clopidogrel group had a lower percentage of hyperlipidemia, prior PCI, glucose, TG and LDL-C. No significant difference was found as to the Angiographic and procedural characteristics (P>0.05 for all). After 12 months' follow-up, the incidence of MACE (12.19% vs. 11.04%, P=0.763) and bleeding (9.38% vs. 13.64%, P=0.205) had no significant difference. After clinical characteristics balanced matching by IPTWs model, we found that Ticagrelor had an unfavorable effect on reducing the incidence of bleeding with the IPTWs model (IPTW-OR, 1.81, 95% CI: 1.18-2.76, P=0.006). Conclusions: This clinical study demonstrated that Clopidogrel should be recommended to elderly CTO patients after PCI, especially those with a high bleeding risk. Trial registration: The study protocol was approved by the Ethics Committee of Air Force Medical University (KY20172019-1).

Abstract Background For infants with severe congenital diaphragmatic hernia (CDH) stabilized with extracorporeal membrane oxygenation (ECMO), early repair on ECMO improves outcome; however when compared to operative repair after ECMO, repair on ECMO is associated with increase bleeding risk and need for blood product transfusions. Methods A retrospective review of 54 patients with CDH placed on ECMO prior to CDH repair was performed. For the subset of patients repaired on ECMO, analysis comparing those repaired early (within 48 h of cannulation) and late (beyond 48 h) on ECMO was performed. Outcomes of interest included survival to discharge, days on ECMO, and postoperative blood product utilization. Results When compared to those patients repaired prior to 48 h of ECMO initiation, 57.7% of patients survived versus 40.9% of late repair patients. For those repaired early, blood product utilization was significantly less. Early repair patients received a median of 72 mL/kg packed red blood cells (PRBC) and 75 mL/kg platelets compared to 151.9 mL/kg and 98.7 mL/kg, respectively (p < 0.05 respectively). There was no difference in median days on ECMO (p = 0.38). Conclusion Our data supports prior reports of improved outcome with repair with 48 h of ECMO initiation and suggests early repair on ECMO is associated with less bleeding and decreased blood product requirement in the postoperative period.
