Pain Management in Primary Care: A Randomized Controlled Trial of a Computerized Decision Support Tool.

Background: Primary care providers manage most patients with chronic pain. Pain is a complex problem, particularly in underserved populations. A technology-enabled, point-of-care decision support tool may improve pain management outcomes.

Race and Ethnicity Do Not Clinically Associate with Quality of Life Among Patients with Chronic Severe Pain in a Federally Qualified Health Center.

Objective: Previous research suggests that race/ethnicity predicts health-related quality of life (HRQL) in chronic pain populations but has not examined this in community settings. This study evaluated this association in 522 community-dwelling patients with chronic pain treated at a Federally Qualified Health Center (FQHC).

Design: Cross-sectional secondary analysis.

Solvated electron yields in liquid and supercritical ammonia--a statistical mechanical treatment.

Earlier the geminate recombination of ions and solvated electrons, produced by ionizing radiation or laser light, was theoretically treated by a model which consisted of a Rydberg atom interacting with the thermodynamic fluctuations of the medium [R. Schiller, J. Chem.

Family medicine: a specialty for all ages.

After a diminishing of its ranks following the post-World War II explosion of growth in medical discoveries, advanced medical technology, and the concomitant specialization of the physician workforce, family medicine is re-establishing itself as a leading medical specialty that has garnered growing interest among recent medical-school graduates. Family physicians provide care for patients of all ages, from newborns to the elderly. In addition to its wide scope of practice, family medicine is characterized by its emphasis on understanding of the whole person, its partnership approach with patients over many years, and its command of medical complexity.

Statistical mechanics of hydrated electron recombination in liquid and supercritical water.

The photochemical yield of hydrated electrons as a function of temperature in liquid and supercritical water is treated in terms of energy fluctuations of the medium. The geminate pair, consisting of a positive ion and a hydrated electron, is regarded as a H-like atom embedded in a completely relaxed dielectric continuum. If the local medium energy is larger than the ionization energy of this atom, the electron escapes its geminate partner.

Generalized Johnson-Nyquist noise: white noise of temperature and pressure at the nanoscale.

White noise is expected to show up in both pressure and temperature at the nanoscale if linear transport equations prevail. This prediction is based on the thermodynamic fluctuation theory in analogy to a new derivation of the Johnson-Nyquist voltage noise. The pressure noise in liquid filled nanotubes, and temperature noise in nanoslabs are estimated and experiments are proposed.

Glucosamine.

Glucosamine is one of the most popular dietary supplements sold in the United States. Most clinical trials have focused on its use in osteoarthritis of the knee. The reported adverse effects have been relatively well studied and are generally uncommon and minor.

Continuous-time random-walk theory of interfering diffusion and chemical reaction with an application to electrochemical impedance spectra of oxidized Zr-1%Nb.

A microscopic theory is developed for the interplay of diffusion and chemical reaction and the results are compared with electrode impedance measurements on an oxide electrode. The theory is based on the ideas of continuous-time random walk and accounts for the interference of diffusion and recombination of the charge carriers in the oxide. The treatment results in a dispersive diffusivity with two time constants, one of them corresponding to the random walk, the other to the reaction.
