Objectives To assess the prevalence of awareness and use of massive open online courses (MOOCs) among medical undergraduates in Egypt as a developing country, as well as identifying the limitations and satisfaction of using these courses. Design A multicentre, cross-sectional study using a web-based, pilot-tested and self-administered questionnaire...

Objectives Limited dose warfarin (LDW) throughout pregnancy was suggested to provide safe and effective anticoagulation in pregnant patients with mechanical heart valve prosthesis (MHVP). Our aim was to study its rate of failure in achieving the INR recommended for high-risk patients with mitral (±aortic) MHVP. Methods A clinical trial was designe...

The continuation of warfarin throughout pregnancy in patients with a mechanical valve prosthesis is a valid anticoagulation regimen, provided that warfarin dose does not exceed 5 mg/day. Two decades after being introduced, the efficacy and safety of this regimen merit evaluation. We performed a systematic review for cases published between January...

Low-dose Warfarin (LDW) throughout pregnancy was suggested to provide safe and effective anticoagulation in pregnant patients with mechanical heart valve prosthesis (MHVP). We aimed to study its rate of failure in achieving target INR of those patients. Methods: Group A: 100 pregnant patients with mitral (+aortic; 24%) MHVP were randomized in a 3:1...

Small dose of Warfarin (⩽5mg/day) was suggested as being safe in pregnant patients with mechanical heart valve prosthesis (MHVP) however; no other oral anticoagulant (OA) alternative has been proposed to cases failing to achieve their target INR. We aimed to suggest the alternative use/shift of those cases to our previously reported safe (OA) Pheni...
