PURPOSE: Pulmonary embolism (PE) is a frequently occurring complication in critically ill patients. Simultaneous occurrence of PE and life-threatening bleeding, may render medical anticoagulation impossible. For these patients, inferior vena cava filters (IVCF) present a valuable therapeutic alternative. The Angel® catheter is a novel IVCF that provides temporary protection from PE and is implanted at bedside. The primary objective of the European Angel® catheter registry is to evaluate the safety and efficacy of this IVCF...

BACKGROUND: Glutaraldehyde (GLA) has been used to crosslink bioprosthetic heart valve (BHVs) tissues to enhance their stability, besides ensuring a satisfactory degree of immunological tolerance. Unfortunately, GLA fixation does not guarantee a complete tissue biocompatibility of BHVs in currently used devices. The interaction between preformed human anti-alpha-Gal antibody and alpha-Gal antigens promotes the calcification of GLA-treated alpha-Gal-positive tissue. Recently, an alarming correlation between the presence of the alpha-Gal epitope and a premature BHVs degeneracy was reported...

Acute cholecystitis (AC) is mainly caused by stones in the gall bladder. Although cholescintigraphy has the highest sensitivity (97%) and specificity (94%) for AC, ultrasound is the most commonly used technique in confirming the diagnosis. Laparoscopic cholecystectomy is the recom-mended treatment of choice; however, in high-risk patients percutaneous gall bladder drainage is an attractive alter-native approach to avoid lesions to the common bile duct. To avoid serious bleeding incidences, it is imperative to pause anticoagulation therapy prior to gall bladder drainage...

Cancer is a known hypercoagulable state that leads to an increased risk of venous thromboembolism (VTE). Low molecular weight heparin remains the preferred anticoagulant for VTE in patients with cancer over vitamin K antagonist. However, the preferred anticoagulant in prevention of stroke and systemic embolism in atrial fibrillation (AF) in patients with cancer has yet to be determined. The direct oral anticoagulants (DOACs) are increasingly being utilized; however their role in cancer has only recently been investigated...

In vitro analysis of mycobacterial pathogenicity or host susceptibility has traditionally relied on the infection of macrophages, the target cell of mycobacteria, despite difficulties reproducing their antimycobacterial activity. We have employed alternative models, namely whole blood and leukocytes in plasma, from QuantiFERON negative individuals, and performed infections with the pathogenic M. tuberculosis, the less pathogenic M. avium, M. kansasii and M. chelonae and the occasionally pathogenic M. gordonae and M...

AIM OF THE STUDY: Patient's knowledge about their treatment is poor, generally speaking. New oral anticoagulants are easier to use compared to antivitamin K, and they are going to increase. This simplification can underestimate their high potential risk. We have assessed patient's knowledge about their direct oral anticoagulants. METHODS: It was a quantitative, observational, multicentric, prospective study, on 50 patients on Direct Oral Anticoagulants. They have been included from November 2015 to February 2017, in Île-de-France...

Fucosylated chondroitin sulfate from sea cucumber Isostichopus badionotus (FCS-Ib) showed potent anticoagulant activities without selectivity. The present study focused on developing safe FCS-Ib oligomers showing selective inhibition of intrinsic factor Xase (anti-FXase) prepared through partial N-deacetylation-deaminative cleavage. The N-deacetylation degree was regulated by reaction time, controlling the resulting oligomer distribution. Structure analysis confirmed the selectivity of degradation, and 12 high purity fractions with trisaccharide-repeating units were separated...

The availability of direct oral anticoagulants has caused a paradigm shift in the management of thrombosis. Rivaroxaban and apixaban are 2 direct oral anticoagulants whose target specificity is activated factor X (FXa). However, it is still not fully understood if and how xabans impact platelet function. This observational study aimed to assess the in vitro platelet function in patients with atrial fibrillation receiving xabans. This was a single-center study quantifying platelet aggregation in 41 patients treated with apixaban or rivaroxaban by light transmission aggregometry...
