Active clinical trials for "Thrombosis"

The issue to be studied is the prevalence of venous thromboembolism (VTE) in hospitalized pediatric patients, and to identify if there are subgroups of patients who may be at higher risk. There are two hypotheses that will be looked at in this study. The first hypothesis is that individual risk factors for VTE in hospitalized pediatric patients are: age >14, obesity, black race, female sex, presence of a central venous line (CVL), traumatic mechanism of injury, orthopaedic surgery, and use of oral contraceptives. The second hypothesis is that risk factors have an additive effect such that risk stratification can be developed to identify those patients with the highest risk.

Deep vein thrombosis (DVT)is devastating disease which influencing the mortality and morbidity of patients at-risk like those undergoing orthopedic surgery. Recent publication suggested HMO-co-A reductase inhibitor (statin) may reduce the occurrence rate of venous thromboembolism in apparently healthy persons. The pleiotropic property of statin like antioxidant, antithrombotic, anti-inflammatory may have effect on the positive results. We are investigating whether rosuvastatin is associated with lower incidence of deep vein thrombosis (DVT) in patients undergoing total knee replacement arthroplasty(TKRA)who are at-high risk for developing DVT

The purpose of the study is to determine the Pharmacokinetics of Low Molecular Weight Heparin (LMWH) in Cancer patients, and compare it to the Pharmacokinetics of LMWH in Patients without cancer. We also intend to detect any correlation between heparanase blood and urine levels and the Pharmacokinetics of LMWH.

To determine the effect of an interventional campaign run by a dedicated "VTE Nurse Educator" over a 6-month period and the effect on prophylaxis rates. To determine the proportion of medically admitted patients with risk factors for VTE. To assess and compare the use of venous thromboembolism (VTE) prophylaxis in hospitalized medical patients versus recommendations and current guidelines. To determine the patient characteristics of those deemed to be at risk of VTE. To determine the proportion of patients receiving appropriate thromboprophylaxis for their risk. To determine the type and duration (where possible) of prophylaxis used.

Registry of Hospitalized patients at Brigham and Women's Hospital treated with Fondaparinux

To evaluate physician response to human alerts that inform the clinician that his/her patient may be eligible for thromboprophylaxis. Medical records are reviewed to evaluate prescribing decision and to evaluate rates of venous thromboembolism.

The purpose of this study is to determine the effectiveness of infrared thermal imaging in adjunctive diagnostic screening for lower limb deep venous thrombosis (DVT).

To use transcranial Doppler (TCD) ultrasound to detect stroke risk in children with sickle cell disease.

The goal of this study is to determine if early placement of a midline catheter in patients with a central venous catheter (CVC) will decrease the number of days the CVC is in place. Patients who are in the medical intensive care unit (MICU) and have a CVC may be approached to join the study. Those who meet study eligibility and provide written consent will be enrolled. The longer the CVC remains in place,the greater the chance of developing an infection or blood clot. Any IV line that is placed (CVC, midline, peripheral line) comes with the risk of infection or blood clots, although that risk is generally less with the midline and peripheral IV lines than a CVC. The treating team will make the decision when to remove the CVC. The timeline of removal will be compared to previous data collected on patients similar to the ones in this study. During their hospital stay, study patients will be monitored for how well the midline catheter is functioning as well as if they develop a catheter related blood clot or infection.

The purpose of the study is to find out whether MAA868, is able to prevent blood clots following your medical condition (surgery for knee replacement)
