BACKGROUND Because of recent concerns about the safety of aprotinin, we updated our 2007 Cochrane review that compared the relative benefits and risks of aprotinin and the lysine analogues tranexamic acid and epsilon aminocaproic acid. METHODS We searched electronic databases, including CENTRAL, MEDLINE, EMBASE, Google and Google Scholar for trials of antifibrinolytic drugs used in adults sch...

BACKGROUND Although direct-acting antivirals can achieve sustained virological response rates greater than 90% in Hepatitis C Virus (HCV) infected persons, at present the majority of HCV-infected individuals remain undiagnosed and therefore untreated. While there are a wide range of HCV serological tests available, there is a lack of formal assessment of their diagnostic performance. We underto...

We aimed to investigate whether periconceptional maternal folate status affects human embryonic cerebellar size and growth trajectories. In a prospective periconceptional cohort participants filled out questionnaires and received weekly transvaginal 3D-ultrasounds between 7+0 and 12+6 weeks gestational age (GA). Viable non-malformed singleton pregnancies were selected for cerebellar measurement...

in this work, removal of c. i. acid red 14 was investigated by pumice stone as a low cost adsorbent. various parameters such as initial dye solution, contact time and ph were studied. removal of dye were increased by increasing of contact time and initial dye solution and deceased by increasing of ph. three isotherm models were studied. linear and non-linear regression analyses were used for de...

BACKGROUND Many patients do not maintain physical activity levels after completion of phase III exercise-based cardiac rehabilitation. DESIGN This study determined the effect of an exercise consultation on maintenance of physical activity and cardiorespiratory fitness 12 months after completion of a phase III exercise programme. Seventy cardiac patients were randomized to the experimental (ex...

OBJECTIVE Tranexamic acid has been suggested to be as effective as aprotinin in reducing blood loss and transfusion requirements after cardiac surgery. Previous studies directly comparing both antifibrinolytics focus on high-risk cardiac surgery patients only or suffer from methodological problems. We wanted to compare the effectiveness of tranexamic acid versus aprotinin in reducing postoperat...
