Studies and Analyses

UCLA investigators reviewed pharmaceutical ads in American medical journals and found that nearly one-third contained no references for medical claims; while the majority of references to published material were available, only a minority of company data-on-file documents were provided upon request; and the majority of original research cited in the ads was funded by or had authors affiliated with the product’s manufacturer.

In one of the largest studies of its kind, UCLA

Participants who quit had a 46% lower death rate

In a new study of 5,887 middle-aged smokers with mild lung disease, those who were randomly assigned to a quit-smoking program had a lower death rate than those assigned to usual care, even though only 21.7 percent of them actually quit smoking.
The annual death rates were 8.8 per 1000 participants in the quit-smoking program and 10.4 per 1000 in the usual care group. The annual death rates for those who actually quit was e

Geoffrey Loftus’ latest research reads more like a murder mystery than a scientific paper.

The University of Washington psychologist’s new study opens with a savage beating and murder on the streets of Fairbanks, Alaska. It features cameo appearances by Julia Roberts and other celebrities. It ends with the conviction of two men based on the eyewitness identification of the defendants from a distance of 450 feet. And, in a post-script, an appeals court orders a new trial

An herb used in traditional Indian medicine to treat diabetes seems to lower blood sugar and insulin levels in a manner similar to prescription drugs, a new study reports.

Researchers gave extracts of the herb Salacia oblonga to 39 healthy adults, and the results were promising. The largest dose of the herb extract – 1,000 milligrams – decreased insulin and blood glucose levels by 29 and 23 percent, respectively. “These kinds of reductions are similar to what we might see with p

Experts at the University of Sheffield have proven conclusively that the functions of language and mathematics are separate in the adult brain, meaning that it is not just linguistic ability that separates us from other animals. Academics and researchers had thought that language may enable higher cognitive functions, and that without it we would lose other high level skills. However, the study has shown that even when the brain is rendered incapable of using or understanding language, it can s

Improved patient outcomes and reduced costs highlight crucial link between electronic medical data and clinical practice guidelines

A new clinical study published today in this month’s American Journal of Managed Care demonstrated that a technology-driven clinical decision support system applying evidence-based clinical guidelines to patient’s electronic medical data helps flag potentially serious clinical errors or deviations from accepted best practices, while making a
