To examine the association between donor plasma cytokine levels and the development of primary graft dysfunction of organs transplanted from deceased donors.
Seventeen deceased donors and the respective 47 transplant recipients were prospectively included in the study. Recipients were divided into two groups: group 1, patients who developed primary graft dysfunction; and group 2, patients who did not develop primary graft dysfunction. Donor plasma levels of TNF, IL-6, IL-1β, and IFN-γ assessed by ELISA were compared between groups.
Sixty-nine organs were retrieved, and 48 transplants were performed. Donor plasma cytokine levels did not differ between groups (in pg/mL): TNF, group 1: 10.8 (4.3 - 30.8) versus group 2: 8.7 (4.1 - 33.1), p = 0.63; IL-6, group 1: 1617.8 (106.7 - 5361.7) versus group 2: 922.9 (161.7 - 5361.7), p = 0.56; IL-1β, group 1: 0.1 (0.1 - 126.1) versus group 2: 0.1 (0.1 - 243.6), p = 0.60; and IFN-γ, group 1: 0.03 (0.02 - 0.2) versus group 2: 0.03 (0.02 - 0.1), p = 0.93). Similar findings were obtained when kidney transplants were analyzed separately.
In this sample of transplant recipients, deceased donor plasma cytokines TNF, IL-6, IL-1β, and IFN-γ were not associated with the development of primary graft dysfunction.

To evaluate the knowledge and acceptance of the public and professionals working in intensive care units regarding organ donation after cardiac death.
The three hospitals with the most brain death notifications in Curitiba were selected, and two groups of respondents were established for application of the same questionnaire: the general public (i.e., visitors of patients in intensive care units) and health professionals working in the same intensive care unit. The questionnaire contained questions concerning demographics, intention to donate organs and knowledge of current legislation regarding brain death and donation after cardiac death.
In total, 543 questionnaires were collected, including 442 from family members and 101 from health professionals. There was a predominance of women and Catholics in both groups. More females intended to donate. Health professionals performed better in the knowledge comparison. The intention to donate organs was significantly higher in the health professionals group (p = 0.01). There was no significant difference in the intention to donate in terms of education level or income. There was a greater acceptance of donation after uncontrolled cardiac death among Catholics than among evangelicals (p < 0.001).
Most of the general population intended to donate, with greater intentions expressed by females. Education and income did not affect the decision. The type of transplant that used a donation after uncontrolled cardiac death was not well accepted in the study population, indicating the need for more clarification for its use in our setting.

The most important topics in fulminant hepatic failure are cerebral edema and intracranial hypertension. Among all therapeutic options, systemic induced hypothermia to 33 - 34ºC has been reported to reduce the high pressure and increase the time during which patients can tolerate a graft. This review discusses the indications and adverse effects of hypothermia.

BACKGROUND AND OBJECTIVES: Failure or delay to diagnose brain death leads to needless occupation of a hospital bed, emotional and financial losses, and unavailability of organs for transplants. The intensive care physician plays an essential role in this diagnosis. This study intended to evaluate intensivists' knowledge concerning brain death. METHODS: Cross-sectional study in 15 intensive care units (ICU) in eight hospitals in the city of Porto Alegre, Brazil. RESULTS: Two hundred forty-six intensivists were interviewed in a consecutive sample between April and December 2005. The prevalence of lack of knowledge regarding the concept was of 17%. Twenty per cent of the interviewees ignored the legal need for complementary confirmatory tests for their diagnosis. Forty-seven per cent considered themselves as having the highest level of assurance to explain the concept to a patient's family members. Twenty-nine per cent erroneously determined the legal time of death for brain dead patients. Pediatric intensivists had less knowledge about the concept, when compared to intensivists for adults (p < 0.001). CONCLUSIONS: Current knowledge of brain death is insufficient in Brazil, among the health care professionals who most often find patients in this situation. Education on the subject is needed to avoid unnecessary expenses, reduce family suffering and increase the offer of organs for transplant.

BACKGROUND AND OBJECTIVES: Since organ transplantation has become the treatment of choice for several end-stage diseases, organ shortage is the most important barrier for the procedures and waiting lists are increasing out of proportion. The objective of this study was to review the best practices concerning family referral and how these issues and others aspects of the donation process can influence consent rates. CONTENTS: Despite the growing number of live donors, the brain death donor continuous to be the major source of organs for transplantation and the only source of extra-renal organs. Many problems have been identified in the donation process, including non-identification of the brain death donor, inadequate care of the donors and family refusal to donation. Increasing the consent rate for donation seems to be a good alternative to reduce organ shortage. CONCLUSIONS: Family decision to donate organs is influenced by several aspects. Highly trained professionals in family referral can affect consent rates.
