To promote an understanding of the implications of current structures and processes for medical necessity determinations that affect everyone, directly or indirectly, the American Health Lawyers Association will devote its biannual Public Interest Colloquium (to be held in February 2005) to the topic. In preparation for the colloquium, the author summarizes the history and current importance of the topic, identifies stakeholders in the system and their interests, and sets forth a preliminary list of issues to be considered by the colloquium participants, focusing on potential elements of an ideal system for making medical necessity determinations. 相似文献

A simple method for analyzing nitrite in urine has been developed to confirm and quantify the amount of nitrite in potentially adulterated urine samples. The method involved separation of nitrite by capillary electrophoresis and direct UV detection at 214 nm. Separation was performed using a bare fused silica capillary and a 25 mM phosphate run buffer at a pH of 7.5. Sample preparation consisted of diluting the urine samples 1:20 with run buffer and internal standard, and centrifuging for 5 min at 2500 rpm. The sample was hydrodynamically injected, then separated using -25 kV with the column maintained at 35 degrees C. The method had upper and lower limits of linearity of 1500 and 80 microg/mL nitrite, respectively, and a limit of detection of 20 microg/mL. The method was evaluated using the National Committee for Clinical Laboratory Standards (NCCLS) protocol (Document EP10-A2), and validated using controls, standards, and authentic urine samples. Ten anions, ClO-, CrO4(-2), NO3-, HCO3-, I-, CH3COO-, F-, SO4-, S2O8(-2), and Cl-, were tested for potential interference with the assay. Interferences with quantitation were noted for only CrO4(-2) and S2O8(-2). High concentrations of Cl- interfered with the chromatography. The method had acceptable accuracy, precision, and specificity. 相似文献

Supraphysiologic doses of testosterone are associated with increased aggression that is hypothesized to be a function of testosterone serum concentrations, mood, and personality. The study attempted to characterize this relationship among weightlifters who were users (n = 10) and nonusers (n = 18) of anabolic steroids. Participants were interviewed using the Modified Mania Rating Scale and Hamilton Rating Scale for Depression to assess mood, the Buss-Durkee Hostility Inventory (BDHI) and Point Subtraction Aggression Paradigm (PSAP) to assess aggression, and the Personality Disorder Questionnaire (PDQ-R) to assess personality. Blood samples were obtained for the determination of total, free, and weakly bound testosterone. Comparisons of continuous variables between testosterone users and non-users were performed with a parametric (unpaired t-test) or non-parametric (Mann-Whitney) test where appropriate. Correlations with testosterone were examined separately for testosterone users and non-users, using Spearman rank correlation. The subjective (BDHI) and objective (PSAP) assessments of aggression found that supranormal testosterone concentrations were associated with increased aggression. However, the PDQ-R results suggest that this finding was confounded by the personality disorder profile of the steroid users, because steroid users demonstrated Cluster B personality disorder traits for antisocial, borderline, and histrionic personality disorder. 相似文献

This article explores the potential evisceration of the deterrence function of punitive damages, one of the only economic incentives that deters insurance companies from opportunistically breaching their insurance policies. Readers will gain an understanding of why large punitive damages awards are essential in the insurance coverage field and how such awards may implicate due process standards. The article explains the constitutional limitations set forth by the U.S. Supreme Court in imposing punitive damages, and provides a roadmap of how lower courts and practitioners are presently applying these rules. 相似文献

The BiDil story offers an ideal opportunity to explore the nature and tone of media representations of race and genetics. For example, was a biological view of race emphasized? Or was the notion of race presented in a critical fashion? 相似文献
