BACKGROUND: Venous thromboembolism (VTE) is a common complication that manifests during and/or after hospitalization, as well as postsurgeries including orthopedic surgeries. Edoxaban is a new oral direct factor Xa inhibitor that has been recently approved for treating VTE in patients who have already been treated with a parenteral anticoagulant and for the prevention of stroke and non-central nervous system systemic embolism in patients with nonvalvular atrial fibrillation. OBJECTIVES: The purpose of this systematic review was to evaluate the safety and efficacy of edoxaban for VTE prophylaxis after lower limb orthopedic surgery...

Drug fever caused by dalteparin-sodium (DS), a low-molecular-weight derivative of heparin, is neither listed in the official drug information and nor published as a case report until today. A preterm infant, born at 26 weeks of gestation, developed fever 2 days after starting a treatment with DS for an intracardial thrombus. The fever reverses soon after changing the treatment to unfractionated heparin and reappeared after reintroduction of DS. Once again, after discontinuing DS, the infant regained normothermia...

BACKGROUND: Venous thromboembolism (VTE) is a leading cause of death in obese patients undergoing bariatric surgery (BS), but there is neither consensus nor high-level guidelines yet on VTE prophylaxis in this specific population. OBJECTIVE: We aimed to evaluate patterns of BS perioperative thromboprophylaxis practices. SETTING: French obesity specialized care centers (CSO), which are tertiary care referral hospitals for the most severe cases of obesity METHODS: A detailed questionnaire survey (11 opened, 15 closed questions) investigating their prophylactic schemes of anticoagulation (molecule, dose, weight-adjustment, duration, associated measures, follow-up) was sent to the 37 CSO...

BACKGROUND: Dalteparin is often used for prophylaxis or treatment of venous thromboembolism during pregnancy, yet there is no laboratory test to accurately reflect its clinical activity. Thromboelastography is a point-of-care monitor of whole blood coagulation. The aim of this study was to determine if serial doses of dalteparin added in vitro to whole blood samples from term, pregnant women are detectable as changes in thromboelastography parameters. METHODS: Thirty healthy parturients presenting for elective caesarean section were recruited...

Background and purpose - Controversies exist regarding thromboprophylaxis in orthopedic surgery. Using data in the nationwide Norwegian Hip Fracture Register (NHFR) with postoperative death and reoperation in the first 6 months after surgery as endpoints in the analyses, we determined whether the thromboprophylaxis in patients who undergo hemiarthroplasty for femoral neck fracture should start preoperatively or postoperatively. Patients and methods - After each operation for hip fracture in Norway, the surgeon reports information on the patient, the fracture, and the operation to the NHFR...

BACKGROUND AND OBJECTIVES: Interdialytic lock solutions should maintain catheter patency and prevent catheter infections. We aimed to determine in which conditions injectable anticoagulant agents (IAAs) combined with ethanol are compatible and to assess the antibiofilm activity of the selected combination and its effects on dialysis catheters (DC). METHODS: The solubility and compatibility of unfractionated heparin (UFH), low molecular weight heparins (LMWHs), heparinoids and fondaparinux (50 to 2,500 U/mL) in 30 to 70% ethanol were determined by visual observation...

Placental mediated pregnancy complications such as preeclampsia and fetal growth restriction (FGR) are common, serious, and associated with increased morbidity and mortality. We conducted a systematic review and meta-analysis to determine the effect of treatment with low-molecular-weight heparins (LMWHs) for secondary prevention of these complications in non thrombophilic women. We searched the electronic databases PubMed, Scopus, and Cochrane Library for randomised controlled trials addressing this question...

BACKGROUND: In a randomized trial (ie, Comparison of Low-Molecular-Weight Heparin versus Oral Anticoagulant Therapy for the Prevention of Recurrent Venous Thromboembolism in Patients with Cancer [CLOT]) that evaluated secondary prophylaxis of recurrent venous thromboembolism (VTE) in patients with cancer, dalteparin reduced the relative risk by 52% compared to oral vitamin K antagonists (VKAs; hazard ratio = 0.48, P = .002). A recent subgroup analysis in patients with moderate to severe renal impairment also revealed lower absolute VTE rates with dalteparin (3% vs 17%; P = ...

Venous thromboembolism (VTE) is a common and serious complication in patients with cancer; treatment guidelines recommend extended therapy of ≥6 months with low-molecular-weight heparin (LMWH) for treatment and prevention of recurrent VTE (rVTE) in this population. This post hoc analysis used data from the CLOT study-a phase III, randomized, open-label, controlled study (N = 676)-to compare the efficacy and safety of dalteparin, a LMWH, versus vitamin K antagonist (VKA) for prevention of rVTE in patients with cancer and renal impairment (creatinine clearance <60 ml/min)...

Unfractionated heparin (UFH) has procoagulant activity in antithrombin/heparin cofactor II (HCII)-depleted plasma. UFH prevents tissue factor pathway inhibitor alpha (TFPIα) from inhibiting the procoagulant enzyme complex, prothrombinase, providing a possible mechanism for its procoagulant activity. The procoagulant potential of UFH and various low molecular weight heparins (LMWHs) were characterized for TFPIα dependence, using thrombin generation assays performed with antithrombin/HCII-depleted plasma. UFH, the LMWHs enoxaparin and dalteparin, and the low anticoagulant LMWH 2-O, 3-O desulphated heparin (ODSH) all promoted thrombin generation, but fondaparinux did not, and this activity was blocked by a TFPIα antibody...

PURPOSE: Although treatments for alopecia are in high demand, not all treatments are safe and reliable. Dalteparin/protamine nanoparticles (D/P NPs) can effectively carry growth factors (GFs) such as fibroblast GF (FGF)-2. The purpose of this study was to identify the effects of FGF-2-containing D/P NPs (FGF-2&D/P NPs) on hair growth. PATIENTS AND METHODS: In this study, the participants were 12 volunteers with thin hair. One milliliter of FGF-2 (100 ng/mL) and D/P NPs (56 μg/mL) was applied and massaged on the skin of the scalp by the participants twice a day...

INTRODUCTION: In contrast to unfractionated heparin (UFH), use of low-molecular weight heparin (LMWH) during pregnancy has not been reported to be associated with a significant decrease in bone mineral density (BMD). The aim of this study was to investigate whether long-term use of LMWH during pregnancy is associated with subsequent decrease in BMD or with increased number of osteoporotic fractures. MATERIALS AND METHODS: In this observational cohort study BMD was measured by dual energy X-ray absorptiometry (DEXA) 4-7years after the last delivery in 152 women...

INTRODUCTION: Venous thromboembolism (VTE) in cancer patients is an increasingly frequent clinical problem. The overall impact of VTE on cancer patients can be considerable. Targeted patient selection by identifying patients with clinically significant recurrent VTE may have wider health economic benefits whilst reducing patient risk through over-treatment. In the UK, dalteparin is one licensed anticoagulant for the extended treatment and prevention of recurrence of VTE in cancer patients...
