“Objective: The objective of the present study was to evaluate whether the outcomes of lung transplantation in patients aged 70 years or older have changed after implementation of the lung allocation score in May 2005.\n\nMethods: Patients aged 70 years or older undergoing primary lung transplantation from 1995 to 2009 were identified from the United Network for Organ Sharing registry. The primary stratification was the pre-lung allocation score era versus lung allocation score era. Risk-adjusted multivariate Cox regression and Kaplan-Meier analyses were

conducted to evaluate the effect SNX-5422 purchase of age 70 years or older on 1-year post-transplant mortality compared with a reference cohort of patients aged 60 to 69 years.\n\nResults: Of the overall 15,726 adult lung transplantation patients in the study period, 225 (1.4%) were 70 years old or

older and 4634 (29.5%) were 60 to 69 years old. The patients aged 70 years or older were a larger cohort of overall lung transplantation patients in the lung allocation score era compared with before the lung allocation score era (3.1% vs 0.3%, P<.001). In the risk-adjusted Cox analysis, age 70 years PD98059 MAPK inhibitor or older was a significant risk factor for 1-year post-lung transplantation mortality in the pre-lung allocation score era (hazard ratio, 2.00; 95% confidence interval, 1.10-3.62, P=.02) but not in the lung allocation score era (hazard ratio, 1.02; 95% confidence interval, 0.71-1.46; P=.92). Similarly,

Kaplan-Meier 1-year survival was significantly reduced in patients 70 years old or older versus 60 to 69 years old in the pre-lung allocation score era (56.7% vs 76.3%, P=.006) but not in the lung allocation score era (79.0% vs 80.0%, P=.72).\n\nConclusions: Recipients aged 70 years or older were a larger proportion of overall lung transplantation patients after implementation of the lung allocation score. Although associated with significantly increased post-lung transplantation mortality in the pre-lung allocation score era, age 70 years or older is currently associated with outcomes comparable to those of patients selleck products aged 60 to 69 years. Therefore, age 70 years or older should not serve as an absolute contraindication to lung transplantation in the lung allocation score era. (J Thorac Cardiovasc Surg 2012;144:1133-8)”
“In a retrospective study of archival diarrheal stool samples collected from 1974 to 1991 at Children’s Hospital National Medical Center, Washington, DC, we detected three genotype G9P[8] viruses in specimens collected in 1980, which represented the earliest human G9 viruses ever isolated. The VP7 genes of two culture-adapted 1980 G9 viruses were phylogenetically related closely to the lineage 2 G9 virus VP7 gene. Unexpectedly, however, the VP7s of the 1980 G9 viruses were more closely related serotypically to lineage 3 VP7s than to lineage 2 VP7, which may be supported by amino acid sequence analyses of the VP7 proteins.
