Long-term survival and prognostic indicators in small (

Objectives: In a matched analysis, we investigated clinical, histopathological, and survival characteristics of small (
Methods: From the Mayo pathology database, we identified 41 consecutive patients with small PaC and 94 matched controls with margin-negative PaC >2 cm. Two experienced pathologists, who were blinded to survival data, independently reviewed tumor stage and differentiation.

Learning and recall in subjects at genetic risk for Alzheimer's disease.

Deficits in delayed recall of learned information may be an early marker of Alzheimer's disease (AD). The apolipoprotein E E4 allele and a positive family history (FH) are both genetic risk factors for AD. The authors cross-sectionally compared performance on the California Verbal Learning Test (CVLT) in 153 prospectively recruited normal elderly subjects (mean age 67 years, mean MMSE=28) stratified by genetic risk into four groups (E4+/FH+, E4+/FH-, E4-/FH+, E4-/FH-).
