INTERNATIONAL NORMALIZED RATIO AND ACTIVATED PARTIAL THROMBOPLASTIN TIME DO NOT PREDICT PLASMA TRANSFUSION IN LIVER TRANSPLANTATION.

Background: Blood loss during liver transplantation (LT) remains a major concern associated with increased morbidity and reduced patient and graft survival. The high complexity of the procedure associated with the multifaceted origin of the bleeding urges early identification of high-risk patients and proper monitoring of hemostasis disorders in order to improve results. The accuracy of international normalized ratio (INR) and activated partial thromboplastin time (aPTT) to evaluate coagulation status in cirrhotic patients has been doubted.

Analysis of two reperfusion techniques in uterine transplantation in an experimental model.

Introduction: Uterine transplantation was developed for the treatment of absolute uterine factor infertility. As it is a new modality of transplantation, there is still room for technical improvement. A factor that impacts graft survival in organ transplantation is the warm ischemia time.

Survival after liver transplantation from hepatitis B-core positive donors at a quaternary care hospital in Brazil.

Background: Liver transplantation is the treatment for many end-stage liver diseases and hepatocellular carcinoma but shortage of available organs poses significant challenge. Many centers have used grafts from donors with positive anti-HBc serology but concerns about potential hepatitis B virus reactivation and de novo hepatitis B infection have raised questions about the safety of this approach. This study aimed to evaluate the survival of liver transplant recipients from anti-HBc-positive-donors and assess the risk of hepatitis B reactivation and de novo hepatitis B.

Global perspectives on donor-derived infections: Brazil and Argentina.

Brazil and Argentina are two of the South American countries that perform the highest number of solid organ transplant procedures globally each year. These procedures are not exempt from risks for the recipient, and there is a risk of donor-derived infections. Risk mitigation measures for disease transmission from donor to recipient are essential, and biovigilance systems play a crucial role to inform authorities and provide data for the definition of screening procedures and prevention of donor-derived infections.

En Bloc Simultaneous Liver-Kidney Transplantation Compared to the Traditional Technique: Results From a Single Center.

Background: Simultaneous liver-kidney transplantation is indicated for patients with concomitant end-stage liver disease and end-stage renal disease. The traditional technique involves separate implantations of the liver and the kidney. In the en bloc approach, the liver is recovered en bloc with the right kidney and the donor renal artery is anastomosed to the donor splenic artery.
