Got grapes? UCLA researchers have demonstrated how resveratrol, an antioxidant derived from grapes and found in wine, works to inhibit growth of the bacteria that causes acne.
The team also found that combining resveratrol with a common acne medication, benzoyl peroxide, may enhance the drug's ability to kill the bacteria and could translate into new treatments.
WASHINGTON D.C., September 30, 2014 – Applying a well-known optical phenomenon called thin-film interference, a group of researchers at Harvard University has demonstrated the ability to "paint" ultra-thin coatings onto a rough surface -- work that holds promise for making future, flexible electronic devices, creating advanced solar cells and detailing the sides of next-gen rocket ships and spacecraft with extremely lightweight decorative logos.
Because heart cells cannot multiply and cardiac muscles contain few stem cells, heart tissue is unable to repair itself after a heart attack. Now Tel Aviv University researchers are literally setting a new gold standard in cardiac tissue engineering.
A recent study completed at the University of Eastern Finland shows that dietary polyunsaturated fatty acids may reduce the risk of coronary heart disease. The sources of polyunsaturated fatty acids include fish, vegetable oils, and nuts. The findings were published in Arteriosclerosis, Thrombosis & Vascular Biology, an esteemed journal of the American Heart Association.
The authors analyzed data on 13,692 mechanically ventilated patients from 104 U.S. hospitals during the years 2003 – 2009. They found that overall ICU mortality was 19.7 percent in propofol treated patients as compared to 28.8 percent in midazolam treated patients, and 19.3 percent for propofol compared to 25.2 percent for lorazepam treated patients. Those treated with benzodiazepines also spent significantly more time on mechanical ventilation, and a longer time in the ICU.
ARLINGTON HEIGHTS, Ill. (September 30, 2014) – People who suffer from asthma may think there's not a lot they can do to control their asthma besides properly taking medications and avoiding allergic triggers.
Administration of high-dose vitamin D3 compared with placebo did not reduce hospital length of stay, intensive care unit (ICU) length of stay, hospital mortality, or the risk of death at 6 months among patients with vitamin D deficiency who were critically ill, according to a study published in JAMA. The study is being posted early online to coincide with its presentation at the European Society of Intensive Care Medicine annual congress.
WASHINGTON, DC (September 30, 2014)— A new national study finds that health professions schools report an overall positive impact from the use of holistic review – a university admissions process that assesses an applicant's unique experiences alongside traditional measures of academic achievement such as grades and test scores. The report, Holistic Admission in the Health Professions, released today is the first large-scale study to examine the prevalence and effectiveness of holistic review across multiple health disciplines at universities nationwide.
Genomic data could predict whether statins will benefit a patient or not, according to an article in the open access journal Genome Biology. The research suggests that genomic data alone can explain around 15% of patients' responses to a cholesterol-lowering statin, and further studies could increase the accuracy of these predictions.
A new California ballot initiative being touted as a patient safety measure may create more problems than it solves, according to two new commentaries being published in Annals of Internal Medicine. Proposition 46, the Medical Malpractice Lawsuits Cap and Drug Testing of Doctors Initiative, would mandate random drug and alcohol testing of physicians and quadruple the cap on medical malpractice awards to $1.1 million.
(SACRAMENTO, Calif.) —A 2004 California law mandating specific nurse-to-patient staffing standards in acute care hospitals significantly lowered job-related injuries and illnesses for both registered nurses and licensed practical nurses, according to UC Davis research published online in the International Archives of Occupational and Environmental Health. The study is believed to be the first to evaluate the effect of the law on occupational health.
(SACRAMENTO, Calif.) —Short questionnaires used to identify patients at risk for depression are linked with antidepressant medications being prescribed when they may not be needed, according to new research from UC Davis Health System published in the September-October issue of the Journal of the American Board of Family Medicine.
Before undergoing heart imaging procedures involving radiation, healthcare providers should help patients understand why the procedure is needed and its potential benefits and risks, including risks related to radiation exposure, according to a new scientific statement in the American Heart Association's journal Circulation.
Information is lacking on most implanted medical devices cleared by the U.S. Food and Drug Administration despite a legal requirement that companies submit scientific evidence about the devices' substantial equivalence to other devices already on the market.
MINNEAPOLIS – According to a new position statement from the American Academy of Neurology (AAN), the risk of death, overdose, addiction or serious side effects with prescription opioids outweigh the benefits in chronic, non-cancer conditions such as headache, fibromyalgia and chronic low back pain. The position paper is published in the September 30, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology.
