A number of poorly characterized genetic modifiers contribute to the extensive variability of von Willebrand disease, the most prevalent bleeding disorder in humans. We find that a genetic lesion inactivating the murine ST3Gal-IV sialyltransferase causes a bleeding disorder associated with an autosomal dominant reduction in plasma von Willebrand factor (VWF) and an autosomal recessive thrombocy...

OBJECTIVE To systematically review the literature and to quantitatively evaluate the efficacy and safety of extended pharmacologic treatment of venous thromboembolism (VTE) through network meta-analysis (NMA). METHODS A systematic literature search (MEDLINE, Embase, Cochrane CENTRAL, through September 2014) and searching of reference lists of included studies and relevant reviews was conducte...

B ivalirudin and cangrelor are 2 intravenous drugs, 1 for anticoagulation and the other for antiplatelet therapy, with a rapid onset of action, thus in theory perfectly adapted to percutaneous coronary intervention (PCI) that requires simultaneous thrombin and platelet inhibition. These effects are especially needed for mechanical coronary reperfusion of acute patients such as those presenting ...

Electrocoagulation bronchoscopy biopsy forceps may prevent bleeding, but could also impair the quality of the specimens obtained. Patients with endobronchial lesions during bronchoscopy underwent six endobronchial biopsies each with a hot biopsy forceps, alternating between with electrocoagulation ("hot") and without ("cold"). Bleeding was quantified on a scale of 1-4, with 1 being no bleeding....

BACKGROUND AND OBJECTIVES Desmopressin is the treatment of choice for patients with von Willebrand's disease and mild hemophilia A. This compound is also useful in other congenital and acquired disorders of hemostasis, reducing the need for blood derivatives with the inherent risks of infections and alloimmunization. The following article presents a pilot study on the safety and efficacy of des...

Norplant, a systemic contraceptive, has been used extensively throughout the world. A major problem for consumers utilizing Norplant has been irregular, unpredictable uterine bleeding or spotting. This study seeks to determine whether or not an appropriate treatment could be found that will reduce the incidence of spotting and bleeding. Both a pilot study and an interim report of a multi-center...

OBJECTIVE Scoliosis surgery involves major blood loss and frequently requires blood transfusion. The cost and risks involved in using allogeneic blood have motivated investigation of methods capable of reducing patients' bleeding during operations. One of these methods is to use antifibrinolytic drugs, and tranexamic acid is among these. The aim of this study was to assess the use of this drug ...

Endothelium-derived relaxing factor, now identified as nitric oxide (NO), is a labile humoral agent formed by vascular endothelial cells from L-arginine. NO mediates the action of substances that induce endothelium-dependent relaxation and plays a role in regulating blood pressure. In this study we investigated whether NO is involved in the pathogenesis of the bleeding tendency associated with ...

Objective: To determine the prevalence of acute gastro-intestinal tract bleeding and factors associated with it in patients undergoing Primary PCI after myocardial infarction.
 Study Design: Analytical Cross sectional study.
 Place Duration Study: Department Interventional Cardiology, Tertiary Cardiac Care Center, Rawalpindi Pakistan, from May 2021 to April 2022.
 Methodology: Fi...

BACKGROUND Transradial percutaneous coronary intervention (PCI [TRI]) does not involve catheter manipulation in the descending aorta, whereas transfemoral PCI (TFI) does. Therefore, the risk of acute kidney injury (AKI) after PCI might be influenced by vascular access site. We compared risks of AKI and nephropathy requiring dialysis (NRD) among patients treated with TRI and TFI. METHODS AND R...
