Folic acid won’t cut heart, stroke risk, study says
Taking a folic acid supplement does not cut the risk of heart disease or stroke in people with a history of cardiovascular ailments, according to a study published on Tuesday.
Folic acid, also called folate, is a B vitamin. The body uses it to make new cells. Some doctors have recommended the vitamin to ward off cardiovascular disease, the leading cause of death in the United States.
Alcohol in moderation may extend life
Moderate drinking may lengthen your life, while too much may shorten it, researchers from Italy report. Their conclusion is based on pooled data from 34 large studies involving more than one million people and 94,000 deaths.
According to the data, drinking a moderate amount of alcohol—up to four drinks per day in men and two drinks per day in women—reduces the risk of death from any cause by roughly 18 percent, the team reports in the Archives of Internal Medicine.
Older men treated for early prostate cancer live longer than those who are not
Recent findings from an observational study by researchers at the University of Pennsylvania School of Medicine suggest that men between 65 and 80 years of age who received treatment for early stage, localized prostate cancer lived significantly longer than men who did not receive treatment. The study will be published in the December 13th issue of the Journal of the American Medical Association.
Thanks to better cancer prevention education and the resulting wide-spread increase in using prostate-specific antigen (PSA) screenings, more men are being diagnosed with early-stage and low-or intermediate-grade prostate cancer. Studies have shown that the slow-developing nature of prostate cancer during its earliest stages makes treatment options, such as a radical prostatectomy (surgical removal of the prostate) and radiation therapy, controversial with unpredictable outcomes. Often, recently diagnosed men of this group were advised to just “watch and wait” to see how their situation progressed.
Study helps explain why botulinum toxin is so deadly
A pilot without a map can locate an airport by first finding a nearby landmark, like a big river, and then searching for the airport.
New research from the University of Wisconsin School of Medicine and Public Health (SMPH) and Scripps Research Institute shows how the astonishingly powerful botulinum toxin uses a similar strategy to latch onto nerve cells, the first step in inactivating them.
Antibiotic ear drops favored over popular oral antibiotics for ear infections
A multicenter study on treating common ear infections in children with ear tubes adds to a growing body of evidence that favors antibiotic ear drops over antibiotics swallowed in pill or liquid form in such cases, a UT Southwestern Medical Center researcher reports.
The latest study, involving 80 children, showed that antibiotic ear drops performed better and faster in treating middle ear infections in children with ear tubes than merely taking oral antibiotics such as swallowing a pill or liquid. The findings are available online in the journal Pediatrics.
