Stopping smoking shortly before surgery is not associated with increased postoperative complications
CHICAGO -- A meta-analysis of nine previous studies found that quitting smoking shortly before surgery was not associated with an increased risk of postoperative complications, according to a report published online today that will appear in the July 11 print issue of Archives of Internal Medicine, one of the JAMA/Archives journals.
CHICAGO – Patients with a recent onset of Parkinson disease have a high prevalence of vitamin D insufficiency, but vitamin D concentrations do not appear to decline during the progression of the disease, according to a report in the March issue of Archives of Neurology, one of the JAMA/Archives journals.
CHICAGO – Regular consumption of fish and omega-3 fatty acids found in fish is associated with a significantly reduced risk of developing age-related macular degeneration in women, according to a report posted online today that will appear in the June issue of Archives of Ophthalmology, one of the JAMA/Archives journals.

PITTSBURGH, March 14 – If all eligible patients filled their prescriptions through a $4 generic drug program, the societal savings could amount to nearly $6 billion, according to a University of Pittsburgh Graduate School of Public Health (GSPH) study. Published in the March 14 issue of Archives of Internal Medicine, the study is the first to evaluate the potential national savings from a broad use of discounted generic medication programs that are available at many retail stores' pharmacies.
The so-called cellular slime mold, a unicellular organism that may transition into a multicellular organism under stress, has just been found to have a tissue structure that was previously thought to exist only in more sophisticated animals. What's more, two proteins that are needed by the slime mold to form this structure are similar to those that perform the same function in more sophistical animals.
Providing clues into why the severity of a common parasitic infection can vary greatly from person to person, a new Johns Hopkins study shows that each one of three strains of the cat-borne parasite Toxoplasma gondii sets off a unique reaction in the nerve cells it invades.
Past research suggests that the parasite, estimated to infect 25 percent of people worldwide, can trigger or exacerbate psychotic symptoms and schizophrenia in genetically predisposed people.
New research by Chongsuk Ryou, researcher at the UK Sanders-Brown Center on Aging and professor of microbiology, immunology and molecular genetics in the UK College of Medicine, may shed light on possible treatments for prion diseases.
New Rochelle, NY, March 14, 2011–Adolescents and young adults are neither children nor adults and those affected by cancer require targeted care that crosses the boundaries between pediatric and adult oncology, according to several pioneers in this still-developing field of adolescent and young adult oncology. An illuminating roundtable discussion by these experts will be published in the premier issue of Journal of Adolescent and Young Adult Oncology, a multidisciplinary peer-reviewed publication of Mary Ann Liebert, Inc.
A variety of plant seedlings suffer most from competition when planted with close relatives, and grow best when planted alongside distant relatives in field soils, researchers from Case Western Reserve University and the University of California, Davis, have found.
And, when seeds of the same species are buried among relatives in the field, the seeds germinate at a higher rate and grow better early in life in close relatives' habitats than distant relatives' habitats.
The work will be published in the Proceedings of the National Academy of Sciences March 14.
According to classical ecology, when two species compete for the same resource, eventually the more successful species will win out while the other will go extinct. But that rule cannot explain systems such as the Amazon, where thousands of tree species occupy similar ecological niches.
