Comprehension and satisfaction are relevant criteria for evaluating the effectiveness of information provided to family members of intensive care unit (ICU) patients. We performed a prospective randomized trial in 34 French ICUs to compare comprehension of diagnosis, prognosis, treatment, and satisfaction with information provided by ICU caregivers, in ICU patient family representatives who did (n = 87) or did not (n = 88) receive a family information leaflet (FIL) in addition to standard information. An FIL designed specifically for this study was delivered at the first visit of the family representative: it provided general information on the ICU and hospital, the name of the ICU physician caring for the patient, a diagram of a typical ICU room with the names of all the devices, and a glossary of 12 terms commonly used in ICUs. Characteristics of the ICUs, patients, and family representatives were similar in the two groups. The FIL reduced the proportion of family members with poor comprehension from 40.9% to 11.5% (p < 0.0001). In the representatives with good comprehension, the FIL was associated with significantly better satisfaction (21 [18 to 24, quartiles] versus 27 [24 to 29, quartiles], p = 0.01). These results indicate that ICU caregivers should consider using an FIL to improve the effectiveness of the information they impart to families.

Hepatocyte transplantation might represent a potential therapeutic alternative to liver transplantation in the future; however, transplanted cells have a limited capacity to repopulate the liver, as they do not proliferate under normal conditions. Recently, studies in urokinase (uPA) transgenic mice and in fumarylacetoacetate hydrolase (FAH)-deficient mice have shown that the liver can be repopulated by genetically engineered hepatocytes harboring a selective advantage over resident hepatocytes. We have reported that transgenic mice expressing human Bcl-2 in their hepatocytes are protected from Fas/CD95-mediated liver apoptosis. We now show that Bcl-2 transplanted hepatocytes selectively repopulate the liver of mice treated with nonlethal doses of the anti-Fas antibody Jo2. FK 506 immunosuppressed mice were transplanted by splenic injection with Bcl-2 hepatocytes. The livers of female recipients were repopulated by male Bcl-2 transgenic hepatocytes, as much as 16%, after 8 to 12 administrations of Jo2. This only occurred after anti-Fas treatment, confirming that resistance to Fas-induced apoptosis constituted the selective advantage of these transplanted hepatocytes. Thus, we have demonstrated a method for increasing genetic reconstitution of the liver through selective repopulation with modified transgenic hepatocytes, which will allow optimization of cell and gene therapy in the liver.
