Decreasing body mass index is associated with cerebrospinal fluid markers of Alzheimer's pathology in MCI and mild dementia.

Background: Several studies have identified an association between body mass index (BMI) and the incidence and severity of Alzheimer's disease (AD) but this relationship is not fully understood.

Objective: The primary objective of this study was to assess the possible association between BMI and cerebrospinal fluid (CSF) biomarkers of AD pathology in subjects with normal cognition and cognitive impairment. The secondary objective was to test whether BMI may contribute to improve the accuracy of a clinical model to predict AD pathology in memory clinic patients with cognitive impairment.

Tacrolimus monotherapy in liver transplantation: one-year results of a prospective, randomized, double-blind, placebo-controlled study.

Background: Minimal immunosuppression (IS) is desirable in organ transplantation to reduce side effects and to promote the process of tolerance induction.

Material And Methods: Between February 2000 and September 2004, 156 adults (>15 years old) receiving a primary liver graft were enrolled in a prospective, randomized, double-blind, placebo-controlled, investigator-driven single-center study comparing tacrolimus (TAC)-placebo (PL) and TAC-low-dose, short-term (64 days) steroid (ST) IS. There were no exclusion criteria at moment of randomization.

Validation of a liquid chromatography-mass spectrometric assay for tacrolimus in liver biopsies after hepatic transplantation: correlation with histopathologic staging of rejection.

The aims of this work were both to validate a sensitive and specific method to quantify tacrolimus (TAC) in liver biopsies after hepatic transplantation and to evaluate the predictive value of either tissue or blood TAC concentrations for rejection in 146 adult patients under a TAC-based immunosuppression. Trough blood levels were monitored daily during the hospital stay by immunoassay. Liver biopsies were routinely performed at day 7 posttransplantation.

Extension of the adult hepatic allograft pool using split liver transplantation.

Background: The ever increasing number of, especially, adults waiting for a liver transplantation necessitates to develop techniques allowing to extend the available donor liver pool.

Materials And Methods: Between November 1988 and December 2004, 37 (6.6%) of 559 adults underwent split liver transplantation at Saint-Luc Hospitals.
