Question: Renal dysfunction is common after liver transplantation (LT). The aim of our study was to assess the prevalence of renal dysfunction 5 yr after LT and to identify risk factors for the development of this complication.', 'A total of 134 adult patients underwent LT from 1987 to 1998 and 74.6% of them were alive 5 yr after. Pre-LT, 1 and 5 yr post-LT renal function were calculated by Cockroft and modification of diet in renal disease (MDRD) formula. Since 1987 glomerular filtration rate (GFR) has been measured by radiolabeled tracers clearance (RTC). Risk factors for GFR < 50 mL/min were analyzed using a multivariate logistic regression model.', 'Mean pre-LT GFR was 79 and 85 mL/min with Cockroft and MDRD respectively; 11% of the patients had a GFR <or= 50 mL/min. 5 yr after LT, mean GFR was 63, 61 and 70 mL/min with MDRD, Cockroft and RTC respectively, GFR decreased by 26%, and 25% of the patients had a GFR < 50 mL/min. Independent risk factors associated with impaired renal function were: trough levels of cyclosporin A (CyA) >or= 150 microg/L or tacrolimus (FK) >or= 10 microg/L at 1 yr and CyA >or= 100 microg/L or FK >or= 8 microg/L at 5 yr.

Question: Treatment of rheumatoid arthritis (RA) with tumor necrosis factor (TNF)-blocking agents, including etanercept and infliximab, has resulted in reductions in the radiographic progression of RA. However, the exact mechanism by which this protection occurs has not been determined. In order to add to such knowledge, we investigated the effect of anti-TNF therapy on the expression of osteoprotegerin (OPG) and receptor activator of NF-kappaB ligand (RANKL) in synovial tissue.', "The expression of OPG and RANKL in synovial biopsy specimens was evaluated by immunohistochemistry. Serial synovial biopsy specimens were obtained from 18 patients with RA, before and after treatment with etanercept (9 patients) or infliximab (9 patients). Biopsy specimens were evaluated by double-blind semiquantitative analysis and image analysis. The in vitro effect of TNF antagonists on the RANKL/OPG expression in osteoblasts and endothelial cells was evaluated by Western blotting. Statistical analysis was performed using Wilcoxon's signed rank test, followed by the Bonferroni correction for multiple comparisons of paired samples. The results of in vitro experiments were evaluated by one-way analysis of variance, with Tukey's post hoc test.", 'Treatment with both infliximab and etanercept increased the expression of OPG in synovial tissue. After 8 weeks of treatment, neither infliximab nor etanercept influenced RANKL expression. In both groups of patients, the RANKL:OPG ratio decreased following therapy. In vitro, both of the TNF antagonists mimicked the in vivo effect, inducing a decrease in the RANKL:OPG ratio in TNF-primed osteoblasts and endothelial cells.

Question: Substance use and crime/recidivism are irrevocably linked. We explore the nuances of this association by highlighting the prevalence, trends, and correlates of substance use dsorders in a large group of probationers/parolees.', 'We examined SUDs among probationers and parolees in the United States using data from the National Study on Drug Use and Health (NSDUH). Logistic regression models were computed to examine eight distinct outcomes: alcohol abuse, illicit drug abuse, marijuana/hashish abuse, comorbid alcohol and illicit drug abuse, alcohol dependence, illicit drug dependence, marijuana/hashish dependence, and comorbid alcohol and illicit drug dependence.', 'Probationers/parolees have high prevalence rates across all SUDs categories and these trends have been relatively constant. Prevalence rates for alcohol abuse and dependence are two to six times higher than for marijuana and other illicit drug abuse and dependence. Key correlates of substance abuse for probationers/parolees include: age, gender, race/ethnicity, education, income, risk propensity, crime/violence measures, and comorbid substance abuse. Similar correlates were found for substance dependence, in addition to employment and mental health treatment.
