OBJECTIVES Hyperhomocysteinaemia is a well-known risk factor for venous thromboembolic disease (VTD). However, it is not clear whether homocysteine (Hc) itself or a related metabolite or a cofactor is primarily responsible for VTD. We carried out a case-control study to investigate whether vitamin concentrations that are involved in the Hc metabolism are(More)
The natural history of patients with venous thromboembolism (VTE) who develop a major bleeding complication while on anticoagulant therapy is not well known. RIETE is a prospective registry of consecutive patients with symptomatic, objectively confirmed, acute VTE. The clinical characteristics, treatment decisions and outcome of all VTE patients who had(More)
Long-term therapy with low-molecular-weight heparin (LMWH) is the treatment of choice for cancer patients with venous thromboembolism (VTE). However, the ideal doses of LMWH have not been thoroughly studied. We used the RIETE Registry data to assess the influence of the daily LMWH dosage on outcome during the first three months after VTE. We used propensity(More)
BACKGROUND Patients who have experienced a recent major bleeding episode are usually excluded from clinical studies of venous thromboembolism (VTE) treatment. Therefore, recommendations based on evidence from clinical trials may not be suitable for these patients. The Registro Informatizado de la Enfermedad TromboEmbolica (RIETE) is a multicenter,(More)
Current guidelines of antithrombotic therapy suggest early initiation of vitamin K antagonists (VKA) in non-cancer patients with venous thromboembolism (VTE), and long-term therapy with low-molecular weight heparin (LMWH) for those with cancer. We used data from RIETE (international registry of patients with VTE) to report the use of long-term anticoagulant(More)
AIM To assess the prevalence and prognostic significance of additional intrathoracic findings (AIFs) in patients with cancer and pulmonary embolism (PE). AIFs were considered alterations other than the characteristic ones intrinsic to PE or changes in cardiovascular morphology. METHODS Subjects have been taken from a Spanish national multidisciplinary and(More)
Treatment of patients with cancer-associated venous thromboembolism (VTE) remains a major challenge. The modified Ottawa score is a clinical prediction rule evaluating the risk of VTE recurrences during the first six months of anticoagulant treatment in patients with cancer-related VTE. We aimed to validate the Ottawa score using data from the RIETE(More)
BACKGROUND Women presenting with uterine bleeding during the course of anticoagulant therapy for venous thromboembolism (VTE) present a difficult therapeutic dilemma due to the absence of evidence-based recommendations. METHODS We used the RIETE (Registro Informatizado Enfermedad TromboEmbólica) database to assess the clinical characteristics of women(More)
— Telemedicine 1etworks should meet specific Quality of Service (QoS) requirements to guarantee that the users can work with the supported applications in a reliable manner. Therefore it must be verified that network resources satisfy these requirements especially in wireless networks, due to their channel characteristics: Communication over a wireless link(More)
