Abstract

Nonparametric tests of group differences and interaction across strata are developed in which the null hypotheses for these tests are expressed as functions of rho i = P(X > Y) + 1/2P(X = Y), where X refers to a random observation from one group and Y refers to a random observation from the other group within stratum i. The estimator r of the parameter rho is shown to be a useful way to summarize and examine data for ordinal and continuous data.

Pharmacogenetics place in modern medical science and practice.

Pharmacogenetic evidence-based treatment strategies will have major implications for all aspects of the product pipeline, including drug discovery, high throughput target screening protocols, lead optimization, and drug formulation to produce series of medicines for a particular disease which will meet the efficacy needs of the majority of patients. The initial proof of principle experiments involves whole genome screening for DNA variants and determination of specific patterns of variants associated with adverse events of marketed products [SNP Print(sm)]. Pharmacogenetics has the potential of changing the pipeline model of drug discovery, clinical development, and mass customization marketing.

Enhancing transplant patients' adherence to medication therapy.

Despite the importance of proper medication use, many transplant patients do not take their medications correctly. Non-adherence to medication therapy leads to adverse consequences, and practitioners should encourage adherence by transplant patients. This manuscript discusses several aspects of medication taking behavior including: (1) methods of identifying medication non-adherence; (2) models used to identify possible determinants of medication taking behavior; (3) strategies to educate patients concerning their therapy; (4) factors promoting adherence and non-adherence; and (5) practical interventions that we, as practitioners, can employ to enhance adult and pediatric transplant patients' adherence to therapy. By using the strategies suggested, transplant patients' adherence to medication therapy may be enhanced and patients' quality of life improved.
