a:4:{s:10:"Background";s:363:"The largest percentage of failed in vitro fertilization (IVF) cycles are due to lack of implantation. As hereditary thrombophilia can cause in placentation failure, it may have a role in recurrent IVF failure. The aim of this case-control study was to determine whether or not hereditary thrombophilia is more prevalent in women with recurrent IVF failures.";s:19:"Ma...

OBJECTIVES To study the prevalence of factor V Leiden mutation in patients with chronic venous insufficiency and venous leg ulcers, compared with a control group, and to find out whether factor V Leiden mutation is more frequent in patients with chronic venous insufficiency and a history of deep venous thrombosis. DESIGN A case control study. SETTING Three outpatient dermatological clinics....

AIM To determine the prevalence of factor V Leiden mutation in patients with different presentation of venous thromboembolic disease and healthy individuals in the Republic of Macedonia. METHODS The retrospective case control study involved 190 patients with venous thromboembolic disease and 200 healthy individuals, who were screened for the presence of factor V Leiden mutation, using a polym...

Oral contraceptive use in women with factor V Leiden is associated with increased rates of venous thromboembolic events (VTEs). However, the effects of hormone replacement therapy (HRT) in postmenopausal women with factor V Leiden are not known. A nested case-control study was conducted among women with established coronary disease enrolled in 2 randomized clinical trials of HRT, the Heart and ...

Background: Sickle cell disease occurs due to a mutation in β chains and the substitution of valine instead of glutamate in the sixth position of the ß-chain that causes polymerization and vascular blockage. The aim of this study was to compare the serum C, S proteins and factor V Leiden between sickle cell patients and the control group. Materials and Methods: In this case-control study, perf...

A nucleic acid photocross-linking technology was used in the development of a direct assay for factor V Leiden, a point mutation in the factor V gene (G1691A) that is the most common inherited risk factor for thrombosis. This cross-linking hybridization assay included two allele-specific capture probes and six signal-generating reporter probes; all were modified with a photoactivated cross-link...
