One of the big items about supplements that has been trumpeted in the press of late is the Journal of the American Medical Association's (JAMA) long term study about vitamin E and vitamin C supplementation.

The study has been put forth as a claim that these two supplements are ineffectual for the risks present of major heart disease concerns for men.

In a study published in the Journal of the American Medical Association, 240 milligrams per day of the dietary supplement Ginkgo biloba was found to be ineffective in reducing the development of dementia and Alzheimer's disease in older people.

Researchers led by Steven T. DeKosky, M.D., conducted the trial known as the Ginkgo Evaluation of Memory (GEM) study at four clinical sites over the course of 8 years.

GEM is the largest clinical trial ever to evaluate ginkgo's effect on the occurrence of dementia.

In a recent study published in the Journal of the American Medical Association, men in the 71-93 year old age group who walked less than a quarter-mile per day were almost two times as likely to develop Alzheimer's Disease or other form of dementia than men who walked more than two miles daily.

In another study, also published in JAMA, female nurses, aged 70-81 years who walked 1.5 hours per week, at a leisurely pace, performed better than their less active peers on tests of ...

This week's Journal of the American Medical Association (3 September, the paper version of which seems to arrive early at my house) is notable for having three commentaries on relationships among physicians, academic medicine, and industry.

One, by David Rothman and Susan Chimonas, seemed rather optimistic, while two, by Dr Arnold Relman and by Dr Marcia Angell, were quite dark.

Daniel Fabricant, PhD, and vice president of scientific and regulatory affairs for the Natural Products Association is featured in a Nutra Ingredients post responding to a recent study released in the Journal of the American Medical Association.

The study in question concluded that taking vitamin B did nothing to reduce the risk of cardiovascular events or death caused by coronary heart disease.

“...the study’s exclusion criteria leave much to be desired,” Dr. Fabricant said. From the article:

(Washington University School of Medicine) People have long prized silver as a precious metal. Now, silver-coated endotracheal tubes are giving critically ill patients another reason to value the lustrous metal.

In a study published in the Aug. 20, 2008, issue of the Journal of the American Medical Association, researchers at Washington University School of Medicine in St.

Louis and the NASCENT Investigation Group, report that the silver-coated tubes led to a 36 percent reduction of ventilator-associated pneumonia.

(University of Washington) An infection due to a virus called cytomegalovirus, which most commonly affects people with compromised immune systems, can also affect hospital intensive-care patients who have no immune-system problems, University of Washington researchers have found.

CMV infection is also associated with longer hospital and intensive-care unit stays independent of other causes, according to the study, published July 23 in JAMA, the Journal of the American Medical Association.

When we hear about salmonella these days, we're more likely to think raw eggs than reptiles. But this article in the current issue of the Journal of the American Medical Association reminds us that your family's pet turtles (and other reptiles) can make people just as sick as an undercooked omelet...

(University of Texas M. D. Anderson Cancer Center) When administered before chemoradiation, the common anti-cancer drug cisplatin neither improved disease-free survival nor reduced the number of colostomies needed when compared to the standard treatment for patients with anal canal cancer, according to a study published in the April 23 issue of the Journal of the American Medical Association.

Two studies appearing in tomorrow’s Journal of the American Medical Association have prompted the journal’s editors to call for “drastic action” to prevent drug companies from misrepresenting data from clinical trials.
