Filter by:The Venous thromboembolism (VTE) disease is very frequent, mainly as complications of medical diseases and surgical procedures. It has high prevalence and can lead to severe complications such as pulmonary embolism and postthrombotic syndrome. Although its incidence has been decreasing in recent years, the EP and DVT is still a major public health problem, especially in advanced age. The tracking of this disease through imaging tests in asymptomatic patients does not seem to be a cost-effective, further treatment of complications is expensive and subject to no satisfactory answers are not completely effective in regard to late complications. Therefore, according CAIAFA & BASTOS (2002), effective prophylaxis is the best strategy. The type of prevention to be used should be based on the risk of developing VTE, ie low, medium or high. Framework for a category of risk for the indication of prophylaxis, each patient should be evaluated individually and carefully to the risk of developing VTE. Maffei et al. (2005) describe the "Standards for Clinical Guideline for the prevention, diagnosis and treatment of deep vein thrombosis." According to the guide, the concentration of heparin in 5.000UI is indicated for cases of moderate-risk surgeries. Are classified as "moderate risk" to more surgery (general, gynecological and urological) in patients 40 to 60 years without additional risk factors, and the magnitude of any surgery in patients under 40 years of age who use estrogen ( Annex 01). The dosing schedule chosen in this study also follows the recommendation of the guide and is universally used . According to Maffei et al. (2005), the diagnosis of VTE must be initiated by the history and physical examination, and then must be performed ultrasound Doppler of lower limbs. Thus, the ultra-sonography/doppler examination will be done at the beginning and end of treatment and physical examination will be done periodically throughout the period of monitoring. Following the guidelines proposed by the literature consulted, was established to test this methodology, which aims to demonstrate the non inferiority clinical heparin sodium 5.000UI / 0.25 mL sodium heparin on 5.000UI / 1.0 mL, both produced by Blausiegel Industry and Trade Ltda. in reducing the incidence of VTE. The two formulations are produced from the same material, but have different drug concentrations. Thus, there is a need to scientifically prove that the therapeutic activity and safety of the product test is non-inferior to the comparator drug (APP heparina - 5.000 USP/mL), allowing the sponsoring company to obtain the registration of the product in the concentration of 5000UI /0.25 mL in ANVISA at the proposed therapeutic indication in the study.
Patients that are on total knee/hip replacement initiate prophylaxis treatment on the hospital ground. Once they leave the hospital, as outpatients they continue with the treatment at least during two consecutive weeks. Patients will be instructed to follow treatment recommendations (either LMWH or oral treatment, at physician discretion) and to come back to the surgeon after that period. At that visit, the Treatment Satisfaction Questionaire with Medication (TSQM) test as well as the Moriski-Green Questionaire (measures compliance with medication) will be answer by the patient. TSQM is an self administered validated scale (validated also in spanish) that measures in a generic way the treatment satisfaction to a treatment. Morinski-Green test will be used to measure the compliance degree on medication.
The purpose of this study is to evaluate the efficacy and safety of various doses of YM150 (the experimental drug) compared to enoxaparin in the prevention of venous thromboembolism in patients that are undergoing elective hip replacement surgery.
Enoxaparin is a type of low molecular weight heparin (LMWH), or anticoagulant, used to prevent and treat blood clots. Formation of blood clots, or venous thromboemboli (VTE) in pregnancy can have dangerous and even life-threatening effects on the mother and fetus. Enoxaparin is the preferred medicine to prevent clotting in pregnant patients who are at risk for VTE, because it has been studied to be safe and effective in pregnancy without any harms to the fetus. Although this medication is routinely used and is recommended by several prominent medical groups, the optimal dosing for prevention of VTE is still unclear. The range of standardly prescribed dosing regimens of Enoxaparin includes 40mg daily and 1mg/kg daily, but these two dosing strategies have never been compared in a head to head fashion.
Some cancer patients starting a new chemotherapy regimen are likely to develop blood clots, also known as venous thromboembolism (VTE). Blood clots can cause symptoms and can occasionally be life-threatening. The purpose of this study is to determine if a daily injection of a blood-thinner, dalteparin, for 12 weeks can safely and effectively reduce the frequency of blood clots. Dalteparin is currently approved for prevention of blood clots following surgery and in hospitalized patients but not specifically for cancer outpatients.
Currently standard of care for preventing blood clots in total knee replacement patients is the drug Fragmin which is a daily injection for 10 days after surgery. Patients are in hospital for 3 to 5 days after total knee replacement surgery and patients are taught in hospital to do their injections. The investigators would like to introduce the drug Pradax. Pradax is a Health Canada approved once a day, oral drug that may prevent blood clots in the patient's leg. In this study the patient will receive the standard of care injection drug Fragmin while in hospital but on discharge home the patient will take the oral drug Pradax daily (2 tablets 110mg) for 10 days.
The purpose of this study is to investigate clinical, biochemical and genetic risk factors for venous thromboembolism in pregnancy and pregnancy related vascular complications, and the long-term outcome of such complications including implications for quality of life.
Brigham and Women's Hospital will coordinate a Quality Improvement Initiative at other hospitals that focuses on whether physician notification prior to discharge of high risk VTE patients will reduce the incidence of VTE after hospital discharge.
The purpose of this study is to evaluate the safety and efficacy of therapeutic anticoagulation with tinzaparin during pregnancy via weight-based dosing.
An observational cohort study on safety and efficacy to generate additional data on the benefit/risk profile of the 150 mg dose of Pradaxa in patients with renal impairment
