Six-minute walking test performance is associated with survival in cirrhotic patients.

Background: Patients with cirrhosis are at risk of cirrhotic cardiomyopathy, with resulting cardiac dysfunction and exercise limitations. Six minute walking test (6MWT) assesses functional status and predicts morbidity and mortality in cardiopulmonary diseases.

Aim: To determine if it associates with mortality by analyzing 6MWT performance in patients with liver cirrhosis.

Autonomic dysfunction is common in liver cirrhosis and is associated with cardiac dysfunction and mortality: prospective observational study.

Background: Although autonomic dysfunction has been shown to be associated with liver cirrhosis, the prevalence and prognostic implications are unclear. Abnormal heart rate variability (HRV), a measure of autonomic function, has not been well investigated in cirrhosis.

Objective: To evaluate the prevalence of high-risk HRV parameters in a cohort of cirrhotic patients and their association with cardiac dysfunction and mortality.

São Paulo State Liver Transplantation Supply Chain Study.

Background: The number of liver transplantations is increasing worldwide, and Brazil ranks in the second position. It has one of the biggest public health care systems, which is responsible for the coordination and financial funding of transplantation procedures. Meeting the demands of such a large system of transplantation has become a challenge, particularly when attempting to minimize costs of scarce and expensive resources.

Solid Organ Transplantation Activities Evolution in Brazil: Analysis of 20 Years.

Background: From 1968 until 1997, transplantation-related activities were not properly regulated and were informally practiced. During 20 years, many legal and political changes influenced it.

Objective: To provide a historical overview of the 20 years with a descriptive data analysis of a 20-year data set.
