Results of trial to determine how to prevent future strokes encouraging
UCLA RESEARCH ALERT
FINDINGS:
The results of a major, multicenter clinical trial to determine the best treatment for younger patients who have strokes that are potentially due to a hole in the upper chambers of the heart has provided suggestive but not definitive evidence of the benefit of a new heart hole–closure device.
The trial sought to determine which was the best treatment to prevent further strokes: a combination of closing the hole with a "button" device and anti-clotting medicines, or anti-clotting medicines alone. UCLA was one of the 69 performance sites for the study, called the Recurre...

UCLA study shows promise, offers hope for brain hemorrhage patients
A new endoscopic surgical procedure has been shown to be safer and to result in better outcomes than the current standard medical treatment for patients who suffer strokes as a result of brain hemorrhages, UCLA neurosurgeons have announced.
The findings from their potentially groundbreaking, randomized, controlled phase 2 clinical trial, which was conducted at multiple medical centers, were presented last week at the International Stroke Conference in Honolulu.
"These exciting results offer a glimmer of hope for a condition that most doctors have traditionally considered hopeless," said principal investigator...

Brain rewires itself after damage or injury, life scientists discover
When the brain's primary "learning center" is damaged, complex new neural circuits arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways — often far from the damaged site.
The research, conducted by UCLA's Michael Fanselow and Moriel Zelikowsky in collaboration with Bryce Vissel, a group leader of the neuroscience research program at Sydney's Garvan Institute of Medical Research, appears this week in the early online edition of the journal Proceedings of the National Academy of Sciences.

UCLA researchers provide first evidence of how obstructive sleep apnea damages the brain

Brains with obstructive sleep apnea (left) and without
UCLA researchers have reported the first evidence that obstructive sleep apnea contributes to a breakdown of the blood–brain barrier, which plays an important role in protecting brain tissue.
The discovery, reported in the Sept. 1 issue of the Journal of Neuroimaging, could lead to new approaches for treating obstructive sleep apnea, which affects an estimated 22 million American adults. The disorder causes frequent interruptions in breathing during sleep because the airways narrow or become blocked.
The blood–brain barrier limits harmful...

For post-menopausal women, vaginal estrogens do not raise risk of cancer, other diseases
This study, the first to examine potential adverse health effects in users of vaginal estrogen compared with non-users, suggests that vaginal estrogen therapy is a safe treatment for genitourinary symptoms such as burning, discomfort, and pain during intercourse associated with menopause.AUTHORSThe paper ’s authors are Dr. Carolyn Crandall of UCLA; Kathleen Hovey of the State University of New York at Buffalo; Christopher Andrews of the University of Michigan; Dr. Rowan Chlebowski of City of Hope; Marcia Stefanick of Stanford University; Dr. Dorothy Lane of the State University of New York at Ston y Brook; Dr. Jan Shifre...

Under Affordable Care Act, Americans have had more preventive care for heart health, UCLA study finds
By reducing out-of-pocket costs for preventive treatment, the Affordable Care Act appears to have encouraged more people to have health screenings related to their cardiovascular health,a UCLA study found. Comparing figures from 2006 through 2013, researchers found that more people were screened for diabetes, high cholesterol, cigarette use and high blood pressure — all risk factors for heart disease — after the ACA was implemented than before.But the research, published in the peer-reviewed American Journal of Managed Care, also revealed a disparity between men and women in one key area. Although more men who are at r...

UCLA first on West Coast to perform new procedure to open blocked carotid arteries
Doctors at Ronald Reagan UCLA Medical Center have become the first on the West Coast to perform a new, less-invasive procedure to help clear plaque-ridden carotid arteries. The procedure, which is part of a clinical trial, took place on March 28.
Just as arteries to the heart can become clogged with plaque, causing a blockage, so can the two carotid arteries that supply blood to the brain. Every year, more than 300,000 people in the U.S. are diagnosed with such blockages, which, if left untreated, can reduce or even stop blood flow to the brain, causing a potentially disabling stroke.
Current treat...

In assessing risk of hormone therapy for menopause, dose — not form — matters
FINDINGSWhen it comes to assessing the risk of estrogen therapy for menopause, how the therapy is delivered — taking a pill versus wearing a patch on one’s skin — doesn’t affect risk or benefit, researchers at UCLA and elsewhere have found. But with the commonly used conjugated equine estrogen, plus progestogen, the dosage does. Higher doses, especially over time, are associated with greater risk of problems, including heart disease and some types of cancer, especially among obese women.BACKGROUNDThe Women ’s Health Initiative established the potential of estrogen therapy to increase or decrease the risk of strok...

Sleep biology discovery could lead to new insomnia treatments that don ’t target the brain
UCLA scientists report the first evidence that a gene outside the brain controls the ability to rebound from sleep deprivation — a surprising discovery that could eventually lead to greatly improved treatments for insomnia and other sleep disorders that do not involve getting a drug into the brain.The scientists report that increasing the level of Bmal1 — a critical master gene that regulates sleep patterns — in skeletal muscle makes mice resistant to sleep deprivation.“When we first saw the importance of the muscle, we were surprised,” said senior author Ketema Paul, UCLA associate professor of integrative biolo...

Spacing out after staying up late? Here ’s why
Ever sleep poorly and then walk out of the house without your keys? Or space out while driving to work and nearly hit a stalled car?A new study led by UCLA ’sDr. Itzhak Fried is the first to reveal how sleep deprivation disrupts brain cells ’ ability to communicate with each other. Fried and his colleagues believe that disruption leads to temporary mental lapses that affect memory and visual perception. Their findings are published online today by Nature Medicine.“We discovered that starving the body of sleep also robs neurons of the ability to function properly,” said Fried, the study’s senior author, a profess...

Hookah smoking raises cardiovascular risk comparable to traditional cigarette smoking, study finds
This study is believed to be the first to investigate the effects of hookah smoking on stiffening of the arteries. Studies have shown that as cigarette use continues to decline, hookah smoking is rising, especially among youth and particularly among college students.“We know that flavored tobacco products are frequently the first kind of tobacco product used by youth,” Rezk-Hanna said. “One of the major issues with hookah is the fact that the tobacco is flavored with fruit, candy and alcohol flavors, making hookah the most popular flavored tobacco produc t among this audience.”According to the Food and Drug Admini...
