Benefit and occupational health managers need information on whether new treatments, such as sumatriptan, for migraine headache improve organizational or individual performance. A work productivity outcomes assessment was conducted among sumatriptan-using employees of an Independent Practice Association-health maintenance organization population. Of the 164(More)
We combine ab initio density functional theory with transport calculations to provide a microscopic basis for distinguishing between good and poor metal contacts to nanotubes. Comparing Ti and Pd as examples of different contact metals, we trace back the observed superiority of Pd to the nature of the metal-nanotube hybridization. Based on large scale(More)
Herein we describe a retrospective intent-to-treat evaluation designed to compare the natural course of antidepressant utilization and direct health service expenditures for the treatment of a single episode of major depression among patients enrolled in a multistate network-model health maintenance organization and initially prescribed either a tricyclic(More)
Recent pharmacotherapeutic advances in the treatment of depression have included the development of selective serotonin re-uptake inhibitors (SSRIs). The present study was designed to contrast direct health service expenditures for the treatment of depression among patients enrolled in a health maintenance organization (HMO) and prescribed either the SSRI(More)
The present study was designed to compare direct health service expenditures, for the treatment of depression, among patients enrolled in a health maintenance organization, and prescribed one of three selective serotonin reuptake inhibitors, fluoxetine, paroxetine or sertraline. Information regarding depression-related health service use was derived from(More)

We conducted an open-labeled study to determine whether sumatriptan is more cost-effective than other therapies used to treat migraine headache. We contacted by phone 220 sumatriptan users enrolled in QualMed, a health maintenance organization (HMO) in Spokane, Washington. Of these, 203 met the inclusion criteria and 164 (81%) completed our telephone(More)
We study transport length scales in carbon nanotubes and graphene ribbons under the influence of Anderson disorder. We present generalized analytical expressions for the density of states, the elastic mean free path and the localization length in arbitrarily structured quantum wires. These allow us to analyze the electrical response over the full energy(More)
