Filter by:Rivaroxaban has been developed in the various clinical settings, prevention of venous thromboembolism (VTE)after major orthopedic surgery, prevention of stroke in atrial fibrillation, and in the treatment of acute coronary syndromes. And, in the EINSTEIN-pulmonary embolism (PE) and EINSTEIN-deep venous thrombosis (DVT) programs, rivaroxaban showed non-inferior to standard therapy for the treatment of PE and DVT. However, there has been limited experience of rivaroxaban with secondary VTE prophylaxis in cancer patients. Although cancer-associated DVT or PE was included in previously mentioned EINSTEIN programs, only approximately 5% of the total populations were cancer patients in these studies. Thus, investigators could not automatically translate the results of these studies into the real practice management of cancer-associated VTE patients. Moreover, until now, new oral anticoagulants, including dabigatran and rivaroxaban, have been compared to long-term warfarin therapy, which were well-known inferior agent, but not low molecular weight heparin. In this sense, investigators feel that new oral anticoagulants, particularly rivaroxaban, should be re-investigated in this highly specific patients group. Therefore, investigators are planning to conduct a prospective study evaluating the efficacy and safety of rivaroxaban in Korean patients with cancer-associated VTE.
The purpose of the study is to test whether the health care provider access and training in CERTAIN (Checklist for Early Recognition and Treatment of Acute Illness), would facilitate timely and error free best-practice delivery and minimize preventable death and costly complications in critically ill patients.
The purpose of this study is to determine whether the fixed-dose (prasugrel 10 mg/d vs. 5 mg/d) vs. phenotype (platlet function test by VerifyNow P2Y12 assay)-based prasugrel dose adjustment can match therapeutic zone of platelet reactivity in PCI-treated Asians with acute coronary syndrome
The purpose of this study is to evaluate the safety and efficacy of the Rex Medical Closer™ Vascular Closure System to close the femoral arterial puncture site in subjects who have undergone diagnostic angiography procedures with early ambulation and discharge.
Endoscopic biliary sphincterotomy is a common and important procedure for biliary access and therapy during endoscopic retrograde cholangiopancreatography (ERCP). Bleeding is one of the important complications related to sphincterotomy. This study determines the role of proton pump inhibitor (PPI) in preventing post-sphincterotomy bleeding in patients undergoing ERCP and sphincterotomy.
The purpose of this study is to determine the effect on the (carbon 13 labelled(13C)-Methacetin Breath Test (MBT) of i.v. propranolol, a non-selective beta blocker (NSBB) following initial administration and after chronic use of each of these agents. The correlation of the MBT with Hepatic Venous Pressure Gradient (HVPG) measurement before and after treatment will be assessed. Additionally, the MBT measurements following 60 days of therapy will be compared to the first MBT measurement and to the second MBT measurement, post HVPG. Each patient's subsequent MBT measurement will be compared to his previous MBT results in order to determine his/her response to therapy.
Prolonged Collagen/Epinephrine - closure time (CEPI-CT) indicates platelet dysfunction in CKD patients taking antiplatelet agent. The synthetic vasopressin derivative, Desmopressin (DDAVP) shortens the prolonged bleeding time and improves platelet dysfunction measured by in vitro closure time: CEPI-CT in uremic patients. Desmopressin also antagonizes the in vitro platelet dysfunction induced by GPIIb/IIIa inhibitors, clopidogrel and aspirin. The investigators designed a prospective study to evaluate the effect of desmopressin on platelet function, as measured by in vitro collagen/epinephrine - closure time, in uremic patients who were taking antiplatelet drugs.
The purpose of this study is to determine that a new drug called "Rivaroxaban®" is effective in preventing patients from forming clots after their heart rhythm has been reset by the cardiologist with an electrical device.
Intrauterine devices (IUDs) are an effective form of contraception, but only about 3.4% of women in the US report using them. Women must often wait for their menses to start, or for results of screening for sexually transmitted infections (STIs), before their doctors will place IUDs for them. This is not the case with other birth control methods. Researchers know that it is safe to start oral contraceptive pills, transdermal patches or vaginal rings on the same day of a doctor's visit. In the investigators clinical practice, the investigators often place IUDs on the same day of a woman's visit, but outcomes have not been formally assessed. Currently, there are two kinds of IUDs available in the United States: the ParaGard T380A and the Mirena levonorgestrel intrauterine system (LNG-IUS). The investigators want to know if women who have IUDs placed at any time during their menstrual cycle have different experiences regarding the following, compared to those who have IUDS placed during the first 7 days of their cycle: bleeding or cramping patterns, active pelvic infections, becoming pregnant more often during that first cycle (window pregnancy). Women who come to their provider seeking an IUD for birth control will be asked to participate in this study. The investigators will ask them to keep track of their bleeding and cramping for three subsequent months to see if patterns differ according to the day in their menstrual cycle that the device was inserted. They will be randomly assigned either to record this information on paper, or to send in the information by responding to daily text messages. The investigators want to know if women who have an IUD placed at any time during the menstrual cycle have different outcomes compared to those who have IUDs placed during the first 7 days of their cycle. If the investigators have this information, the investigators can make recommendations to physicians, help counsel patients, and potentially expand access to IUDs.
Tranexamic acid has benn widely used to reduce perioperative bleeding in several operations such as cardiac surgery, liver transplant and joint arthroplasty with good results. Few studies in laminectomy had conflicting results and varying in doses. The objective is to compare perioperative bleeding in major laminectomy between patients receive doubles doses of tranexamic acids (15 mg/kg and 15 mg/kg) with who receive pacebo (0.9% NaCl).
