Device used to close small hole in heart may protect against recurrent stroke
A device used to close a small hole in the heart may benefit certain stroke patients by providing an extra layer of protection for those facing years of ongoing stroke risk, according to the results of a large clinical trial led by UCLA researchers.“It is a major new treatment option for some people,” said Dr. Jeffrey Saver, director of theUCLA Comprehensive Stroke Center and lead author of the study. However, he added, “Using the device is going to have to be a considered clinical decision between the doctor and the patient about who’s the right person to get it.”Thefindings appear in the Sept. 14 New England Jo...

UCLA brain-imaging tool and stroke risk test help identify cognitive decline early
UCLA researchers have used a brain-imaging tool and stroke risk assessment to identify signs of cognitive decline early on in individuals who don't yet show symptoms of dementia.
The connection between stroke risk and cognitive decline has been well established by previous research. Individuals with higher stroke risk, as measured by factors like high blood pressure, have traditionally performed worse on tests of memory, attention and abstract reasoning.
The current small study demonstrated that not only stroke risk, but also the burden of plaques and tangles, as measured by a UCLA brain scan, may influence c...

Blood test identifies risk of disease linked to stroke and dementia
A UCLA-led study has found that levels of six proteins in the blood can be used to gauge a person ’s risk for cerebral small vessel disease, or CSVD, a brain disease that affects an estimated 11 million older adults in the U.S. CSVD can lead to dementia and stroke, but currently it can only be diagnosed with an MRI scan of the brain.“The hope is that this will spawn a novel diagnostic test that clinicians can start to use as a quantitative measure of brain health in people who are at risk of developing cerebral small vessel disease,” said Dr. Jason Hinman, a UCLA assistant professor of neurology and lead author of t...

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...

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...

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...

Today's statin users consume more calories and fat, and weigh more, than their predecessors
People who take statin drugs to lower their cholesterol appear to have developed a false sense of security that could lead to heart disease and other obesity-related illnesses.
A new UCLA-led study suggests that people who took statins in the 2009–10 year were consuming more calories and fat than those who used statins 10 years earlier. There was no similar increase in caloric and fat intake among non–stain users during that decade, researchers said.
In 1999–2000, statin users were consuming fewer calories and less fat than individuals who didn't take these medications, but that is no longer the case. Increase...

Study provides more evidence that sleep apnea is hurting your brain
This study brings us closer to understanding what causes the problems in the brain of people with sleep apnea,” concluded Macey.
The study also found the problem is greater in women with sleep apnea, which may explain the worse apnea-related outcomes in females than males. Studies recently published by the UCLA School of Nursing have shown that brain injury from sleep apnea is much worse in women than men.
The researchers are now looking at whether treatment for obstructive sleep apnea can reverse the damaging effects.
The study was funded by the National Institute of Nursing Research. Other authors of the study were Raj...

UCLA volunteers at free clinic solve small problems for poor that could become catastrophic
It was a typical misunderstanding that could have led to disastrous consequences. The man had run out of medication to control his hypertension. But he couldn’t afford to get it refilled, or so he thought.
So instead of picking up a simple, generic medication at Wal-Mart or Target for $4, the man decided to go without it and unknowingly put himself at risk for a stroke. All because he didn’t realize he could obtain the medication cheaply.
Fortunately, he was one of hundreds who were treated by UCLA health care workers volunteering at the Care Harbor’s annual health clinic held Sept. 11-14 at the Los Angeles Sports Ar...

Has Brazil found the way to better health care?
Under Brazil’s family health program, when a woman learns that she is pregnant, she contacts her local community health agent, who often is a neighbor.
Typically, the agent visits her home to arrange an appointment with the neighborhood’s family health team, and the woman visits the health center for an assessment by a nurse assistant and a physician. During the pregnancy, if she misses a prenatal care appointment, the agent checks in on her at home and helps her reschedule her visit. Any prenatal medications she needs are provided free of charge.
Brazil — home to the world’s fifth-largest population and seventh-l...

UCLA researchers discover method to measure stiffness of arteries in the brain
UCLA researchers have discovered a noninvasive method to measure vascular compliance — that is, the stiffness of arteries — in the human brain, a finding that may have implications for preventing stroke and diagnosing Alzheimer’s disease earlier.
The UCLA team measured the volume of cerebral arteries using a technique called arterial spin labeling. They measured once at the systolic phase of the cardiac cycle, when the heart is pumping blood into the brain, and again at the diastolic phase, when the heart is relaxing.
The stiffer the arteries they tested, the smaller the change in the arterial blood volume between th...

Computational tools could change the way sleep apnea is treated
Imagine that before performing surgery, doctors could consult software that would determine the actual effectiveness of the procedure before even lifting a scalpel.
With the use of a computational model of the human airway being developed by Jeff Eldredge, a professor at the Henry Samueli School of Engineering and Applied Sciences at UCLA, people who suffer from sleep apnea may one day benefit from such a scenario.
Previously, Eldredge, a professor of mechanical and aerospace engineering, had been working on creating models that simulated the interactions between blood and vessel walls with Shao-Ching Huang, an expert in h...

Simply moving 30 minutes a day can lower your health risks
If you spend hours commuting to work and sitting at your desk all day, recent studies about the health hazards of too much sitting probably have hit home.
“Humans are not biologically designed to be sedentary,” says Elisa Terry, program director of the UCLA Recreation Fitwell program. “The more you sit, the unhealthier it is for your body.”
Being sedentary increases risks for diabetes, high blood pressure and poor circulation.
