The Hopkins Verbal Learning Test (HVLT) is a brief verbal learning and memory test with six alternate forms. The HVLT is ideal in situations calling for repeated neuropsychological examinations, but it lacks a delayed recall trial which is essential for the assessment of abnormal forgetting. We present a revised version of the HVLT which includes a delayed recall trial, and therefore delays the yes/no recognition trial. The equivalence of test forms was examined in two separate studies using between-groups and within-subjects research designs. In both studies, the six forms of the revised HVLT (HVLT-R) were found to be equivalent with respect to the recall trials, but there were some modest differences in recognition. Recommendations for the use of the HVLT-R in serial neuropsychological examinations are provided, as well as normative data tables from a sample of 541 subjects, spanning ages 17 to 88 years. 相似文献

OBJECTIVE: Our objective was to investigate the effect of single nucleotide polymorphisms (SNPs) in the P-glycoprotein MDR1 gene on vincristine pharmacokinetics and side effects in childhood acute lymphoblastic leukemia. METHODS: From 52 of 70 children who participated in a previous study on vincristine pharmacokinetics, patient material was available for investigation of the MDR1 genetic variants. The SNPs C3435T and G2677T were determined by use of polymerase chain reaction-restriction fragment length polymorphism. Vincristine side effects were scored retrospectively from patient records. RESULTS: No association was observed between C3435T or G2677T and vincristine pharmacokinetic variables. When haplotypes were assigned, haplotype 1/1 carriers (3435C/2677G) showed a longer elimination half-life than noncarriers (1156 versus 805 minutes, P =.038). In contrast, haplotype 1/2 carriers (3435T/2677G) had a shorter elimination half-life than noncarriers (805 versus 1180 minutes, P =.044). However, this significance was lost after Bonferroni correction for multiple testing. The haplotypes did not affect the other pharmacokinetic parameters, such as clearance and area under the concentration-time curve, suggesting that the observed effect on elimination half-life is of very limited relevance. Moreover, SNPs in the MDR1 gene did not identify patients with an increased risk for vincristine-induced constipation. CONCLUSION: The genetic variants in the MDR1 gene alone cannot explain the large variability in vincristine pharmacokinetics. 相似文献
