Jolani, S. (author), Debray, T.P.A. (author), Koffijberg, H. (author), van Buuren, S. (author), Moons, K.G.M. (author)Individual participant data meta-analyses (IPD-MA) are increasingly used for developing and validating multivariable (diagnostic or prognostic) risk prediction models. Unfortunately, some predictors or even outcomes may not have been measured in each study and are thus systematically missing in some individual studies of the IPD-MA. As a...article 2015

Haas, F.J.L.M. (author), Kluft, C. (author), Biesma, D.H. (author), Schutgens, R.E.G. (author)The objective of the present study was to evaluate the influence of thrombophilia risk factors on variables of a chromogenic thrombin generation assay (ETP) in a setting with acute deep venous thrombosis (DVT) and non-DVT patients. In 152 outpatients suspected for DVT, the results of thrombophilia investigations were known. In all patients,...article 2011

Haas, F.J.L.M. (author), Schutgens, R.E.G. (author), Kluft, C. (author), Biesma, D.H. (author)Introduction. The exclusion of deep venous thrombosis (DVT) by pre-test probability (PTP) and D-dimer in the elderly is safe, but has a low specificity. There is increasing interest in the diagnostic role of thrombin generation in patients with thrombosis. We evaluated the value of thrombin generation in the exclusion of DVT, especially in...article 2011

(author), TNO Defensie en Veiligheid (author)The mechanism of air travel-related venous thrombosis is unclear. Although immobility plays a pivotal role, other factors such as fluid loss may contribute. We investigated whether fluid loss occurred more in individuals with coagulation activation after air travel than in subjects without. As a secondary aim, we investigated whether fluid loss...article 2008

(author), TNO Kwaliteit van Leven (author)Epidemiological studies have shown that hormone therapy (HT) increases the risk of venous thromboembolism in post menopausal women. The mechanism of this increased risk is unknown; however, activation of the haemostatic system is known to contribute to the pathogenesis of venous thromboembolism. In post-menopausal women the estrogen /progestogen...article 2008

(author), TNO Preventie en Gezondheid (author)Murine blood coagulation factors and function are quite similar to those of humans. Because of this similarity and the adaptability of mice to genetic manipulation, murine coagulation factors and inhibitors have been extensively studied. These studies have provided significant insights into human hemostasis. They have also provided useful...article 2007

(author), TNO Kwaliteit van Leven (author)In 2001, the first human study with drug-eluting stents (DES) was published showing a nearly complete abolition of restenosis by using a sirolimus-eluting stent. This success was very encouraging to test new compounds in combination with the DES platform. Nevertheless, several other anti-restenotic compounds have been used in human clinical...article 2006

(author), Jespersen, J. (author)Background: Administration of oral contraceptives (OCs) has profound effects on the plasma levels of haemostasis and inflammation variables, resulting in an increased thrombosis risk. Individuals show large differences in the response of these variables to OCs. Polymorphism in the estrogen receptor-1 (ER1) gene may explain part of this inter...article 2006
