After first episodes of venous thromboembolism (VTE), patients are at increased risk of recurrent VTE and arterial thrombotic events (ATE) compared with the general population, two disorders that are influenced by anticoagulation. However, risk factors of these conditions occurring during and after anticoagulation are little described. Using cause-specific hazard regression models, we aimed to determine risk factors of the composite outcome recurrent VTE/ATE, and separately recurrent VTE or ATE, during and after anticoagulation in patients with first episodes of VTE from a prospective cohort.
View Article and Find Full Text PDFBackground: There is an increased risk of arterial events including major adverse cardiovascular events (MACE) and major adverse limb events (MALE) after venous thromboembolism (VTE). However, their risk factors remain little explored.
Methods: We aimed to determine the risk factors for MACE (acute coronary syndrome/stroke/cardiovascular death) and MALE (limb ischemia/critical limb ischemia/non-traumatic amputation/any limb revascularization) after VTE.
Background: Cardiovascular deaths (CVDTs) are more frequent in patients with venous thromboembolism (VTE) than in the general population; however, risk factors associated with this increased risk of CVDT in patients with VTE are not described.
Methods: To determine the risk factors of CVDT in patients with VTE from a multicenter prospective cohort study, Fine and Gray subdistribution hazard models were conducted.
Results: Of the 3,988 included patients, 426 (10.
Background: It was recently established that patients who developed VTE are at increased risk of major adverse cardiovascular events (MACE) compared with the general population. However, whether the anticoagulation used for VTE influences the risk of MACE remains undescribed.
Research Question: Does the anticoagulant treatment for VTE affect the risk of subsequent MACE?
Study Design And Methods: This study included patients from a large prospective cohort who received only one family of anticoagulant treatment after the acute phase of VTE, including vitamin K antagonist (VKAs) and direct oral anticoagulants (DOACs).
Introduction: The increased risk of arterial thrombotic (ATE) after VTE, particularly when they are unprovoked or cancer-associated has been established. However, the risk factors of ATE after these VTE remain unclear.
Material And Methods: Using cause-specific hazard regression models, we determined risk factors of ATE (myocardial infarction, ischemic stroke, acute limb ischemia, digestive tract ischemia, or renal ischemia) in 2242 patients with unprovoked VTE and in 914 patients with cancer-associated VTE from a multi-center prospective cohort.
Background: Women with a previous venous thromboembolism (VTE) are at risk of recurrence during pregnancy.
Objectives: We aimed to assess the incidence rate of recurrent VTE during pregnancy, according to the period of pregnancy, and the clinical parameters associated with recurrence, in a prospective cohort of women of childbearing age after a first VTE.
Patients/methods: A total of 189 women aged 15-49 years with a first documented VTE were followed until a subsequent pregnancy of at least 20 weeks' gestation between 2000 and 2020.
Background: We aimed to assess whether high pulmonary vascular obstruction index (PVOI) measured at the time of pulmonary embolism (PE) diagnosis is associated with an increased risk of recurrent venous thromboembolism (VTE).
Study Design And Methods: French prospective cohort of patients with a symptomatic episode of PE diagnosed with spiral computerized tomography pulmonary angiography (CTPA) or ventilation-perfusion (V/Q) lung scan and a follow-up of at least 6 months after anticoagulation discontinuation. PVOI was assessed based on the available diagnostic exam (V/Q lung scan or CTPA).
Background: Data on long-term venous thromboembolism (VTE) recurrence risk according to gender are conflicting.
Objective: To evaluate long-term VTE recurrence risk after a first VTE in men and women under 50 years old.
Methods: Since May 2000, 875 consecutive patients (315 men, 560 women) with a first symptomatic VTE under 50 years old were enrolled in a French prospective multicentre cohort study and were followed up as long as possible.
Infants born preterm are at a higher risk of complications and hospitalization in cases of rotavirus diarrhea than children born at term. We evaluated the impact of a rotavirus vaccination campaign (May 2007 to May 2010) on hospitalizations for rotavirus gastroenteritis in a population of children under 3 years old born prematurely (before 37 weeks of gestation) in the Brest University Hospital birth zone. Active surveillance from 2002 to 2006 and a prospective collection of hospitalizations for rotavirus diarrhea were initiated in the pediatric units of Brest University Hospital until May 2010.

The role of these variants in fluindione response is unknown. Our aim was to assess whether genetic factors contribute to the variability in the response to fluindione.

A population-based prospective cohort study was conducted in Brest City and 7 suburban districts (CUB area), North-western Brittany, France (210,000 inhabitants; 5500 births per year). The vaccination program started in May 2007 for a 2-year period for all infants born in the Brest birth zone through pediatricians, public outpatient clinics and general practitioners.
