Multicenter Study
Predictors of long-term survival after liver transplantation for metastatic endocrine tumors: an 85-case French multicentric report.
Liver transplantation (LTx) for metastatic endocrine tumors (MET) remains controversial due to the lack of clear selection criteria. From 1989 to 2005, 85 patients underwent LTx for MET. The primary tumor was located in the pancreas or duodenum in 40 cases, digestive tract in 26 and bronchial tree in five. ⋯ Five-year survival rate was 12% for the 23 patients presenting both unfavorable prognostic factors versus 68% for the 55 patients presenting one or neither factor (p < 10(-7)). LTx can benefit selected patients with nonresectable MET. Patients presenting duodeno-pancreatic MET in association with hepatomegaly are poor indications for LTx.

The survival benefit of deceased donor liver transplantation as a function of candidate disease severity and donor quality.
The survival benefit of liver transplantation depends on candidate disease severity, as measured by MELD score. However, donor liver quality may also affect survival benefit. Using US data from the SRTR on 28 165 adult liver transplant candidates wait-listed between 2001 and 2005, we estimated survival benefit according to cross-classifications of candidate MELD score and deceased donor risk index (DRI) using sequential stratification. ⋯ All recipients with MELD > or =20 had a significant survival benefit from transplantation, regardless of DRI. Transplantation of high-DRI organs is effective for high but not low-MELD candidates. Pairing of high-DRI livers with lower-MELD candidates fails to maximize survival benefit and may deny lifesaving organs to high-MELD candidates who are at high risk of death without transplantation.

Donors after cardiac death: validation of identification criteria (DVIC) study for predictors of rapid death.
Donation after cardiac death (DCD) is uncommon in part because clinicians cannot prospectively identify patients who are likely to die within 60 min of withdrawal of life-sustaining treatments (LST). UNOS criteria exist but have not been validated. Consecutive patients electively withdrawn from LST at five university-affiliated hospitals were prospectively enrolled. ⋯ The data validate the UNOS criteria. Patients with no criteria might be excluded from consideration for DCD. Those with more than one criterion are reasonable candidates, while those with a single criterion should be considered if a 50% failure rate for DCD is acceptable.

Plasma intercellular adhesion molecule-1 and von Willebrand factor in primary graft dysfunction after lung transplantation.
Primary graft dysfunction (PGD), a form of acute lung injury occurring within 72 h following lung transplantation, is characterized by pulmonary edema and diffuse alveolar damage. We hypothesized that higher concentrations of intercellular adhesion molecule-1 (ICAM-1) and von Willebrand factor (vWF) would be associated with the occurrence of PGD. A total of 128 lung transplant recipients among 7 lung transplant centers were enrolled in a multicenter, prospective, cohort study. ⋯ In the multivariate analyses, this finding was independent of all clinical variables except pulmonary artery pressures prior to transplant. There was no association between plasma vWF levels and PGD. We conclude that higher levels of plasma ICAM-1 are associated with PGD following lung transplantation.

Traumatic memories of relatives regarding brain death, request for organ donation and interactions with professionals in the ICU.
Little is known about the memories of relatives after they have been confronted with the brain death of a loved one and the request for organ donation. We conducted this study, guided by Grounded Theory, to explore relatives' experiences, their interactions with health care providers and what influenced their memories. ⋯ Long-term memories of bereaved relatives were influenced by the characteristics of their decision-making style (clear vs. ambivalent) and the perceived quality of the interaction with professionals on the intensive care unit. Organ-focused behavior of professionals and an ambivalent decision-making style of relatives appear to be risk factors for traumatic memories.
