A proposal to grade the severity of early allograft dysfunction after liver transplantation

Paolo Salvalaggio, Rogerio Carballo Afonso, Guilherme Felga, Ben-Hur Ferraz-Neto

DOI: 10.1590/S1679-45082013000100006

Objective:To propose a grading system for early hepatic graft dysfunction.METHODS:A retrospective study from a single transplant center. Recipients of liver transplants from deceased donors, transplanted under the MELD system were included. Early graft dysfunction was defined by Olthoff criteria. Multiple cut-off points of post-transplant laboratory tests were used to create a grading system for early graft dysfunction. The primary outcome was 6-months grafts survival.RESULTS:The peak of aminotransferases during the first postoperative week correlated with graft loss. The recipients were divided […]

The MELD system and liver transplant waiting-list mortality in developing countries: lessons learned from São Paulo, Brazil

Paolo Salvalaggio, Rogerio Carballo Afonso, Luiz Augusto Pereira, Ben-Hur Ferraz-Neto

DOI: 10.1590/S1679-45082012000300004

Objective:The MELD system has not yet been tested as an allocation tool for liver transplantation in the developing countries. In 2006, MELD (Model for End-stage Liver Disease) was launched as a new liver allocation system in São Paulo, Brazil. This study was designed to assess the results of the new allocation policy on waiting list mortality.METHODS:The State of São Paulo liver transplant database was retrospectively reviewed from July 2003 through July 2009. Patients were divided into those who were transplanted […]

Compliance and leadership: the susceptibility of leaders to the risk of corruption in organizations

Renato Almeida dos Santos, Arnoldo José de Hoyos Guevara, Maria Cristina Sanches Amorim, Ben-Hur Ferraz-Neto

In the field of organizational management, the term “compliance” designates the set of actions to mitigate risk and prevent corruption. Programs are composed by formal control systems, codes of ethics, educational actions, ombudsmen, and reporting channels – to mention the most recurrent, which vary according to the sector, the institutional culture, and the strategy. Leadership has a fundamental role in the process of compliance, not only due to its power to implement it, but precisely because it exercises this power, […]

Liver transplant outcome: a comparison between high and low MELD score recipients

Andre Ibrahim David, Maria Paula Villela Coelho, Ângela Tavares Paes, Ana Kober Leite, Bianca Della Guardia, Márcio Dias de Almeida, [...]

DOI: 10.1590/S1679-45082012000100012

Objective:To compare low and high MELD scores and investigate whether existing renal dysfunction has an effect on transplant outcome.METHODS:Data was prospectively collected among 237 liver transplants (216 patients) between March 2003 and March 2009. Patients with cirrhotic disease submitted to transplantation were divided into three groups: MELD > 30, MELD < 30, and hepatocellular carcinoma. Renal failure was defined as a ± 25% decline in estimated glomerular filtration rate as observed 1 week after the transplant. Median MELD scores were [...]

Pancreas transplantation: an overview

Andre Ibrahim David, Ben-Hur Ferraz-Neto, Fernando Levino, Roberto Ferreira Meirelles Junior, Álvaro Pacheco e Silva Filho

ABSTRACT Pancreas transplantation is the only treatment able to reestablish normal glucose and glycated hemoglobin levels in insulin-dependent diabetic patients without the use of exogenous insulin. The evolution of pancreas transplantation in treatment of diabetes was determined by advances in the fields of surgical technique, organ preservation and immunosuppressants. The main complication leading to graft loss is technical failure followed by acute or chronic rejection. Technical failure means graft loss within the first three months following transplantation due to vascular […]
