NASA’s Mars Rover Curiosity to study Sandstones at next waypoint

NASA - National Aeronautics and Space AdministrationPasadena, CA – Variations in the stuff that cements grains together in sandstone have shaped the landscape surrounding NASA’s Curiosity Mars rover and could be a study topic at the mission’s next science waypoint.

On a journey with many months yet to go toward prime destinations on the lower slope of Mount Sharp, Curiosity is approaching a site called “the Kimberley.” Scientists on the team picked this location last year as a likely place to pause for investigation.

American Heart Association says Stroke Patients fare better in Hospitals speeding care

 

American Heart AssociationSan Diego, CA – Hospitals that used key strategies, tools and approaches from the Target: Stroke initiative sped up treatment times, which was associated with fewer stroke patients having complications or dying, according to a science report presented at the American Stroke Association’s International Stroke Conference 2014.

American Stroke Association reports Blood Clot risk remains higher than normal for at least 12 weeks after Women deliver Babies

 

American Stroke Association - American Heart AssociationSan Diego, CAWomen’s blood clot risk remains elevated for at least 12 weeks after delivering a baby — twice as long as previously recognized, according to a large study presented at the American Stroke Association’s International Stroke Conference 2014.

The chance of a blood clot rises during pregnancy, when platelets and other blood-clotting factors increase. «Read the rest of this article»

American Stroke Association says common Infections may increase risk for Memory Decline

 

American Stroke Association - American Heart AssociationSan Diego, CA – Exposure to common infections is linked to memory and brain function — even if the infections never made you ill, according to research presented at the American Stroke Association’s International Stroke Conference 2014.

Researchers found an index of antibody levels caused by exposure to Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus, and herpes simplex viruses 1 and 2 was associated with worse cognitive performance, including memory, speed of mental processing, abstract thinking, planning and reasoning ability. «Read the rest of this article»

American Stroke Association says Moderate Exercise cuts Women’s Stroke Risk

 

American Stroke Association - American Heart AssociationSan Diego, CA – Women don’t need to run marathons or do intense aerobics to reduce their stroke risk. Moderate-intensity exercise — such as brisk walking or playing tennis — may do the trick, according to research presented at the American Stroke Association’s International Stroke Conference 2014.

The study found that moderate exercise also helps offset the increased stroke risk seen with postmenopausal women taking menopausal hormones, but not completely. «Read the rest of this article»

American Stroke Association says there’s an alternative test better at finding potentially dangerous holes in the Heart

 

American Stroke Association - American Heart AssociationSan Diego, CA – An alternative test for measuring blood flow to the brain detected a potentially dangerous hole within the heart of some patients with an unexplained stroke better than a standard test, according to late-breaking science presented at the American Stroke Association’s International Stroke Conference 2014.

In addition, the transcranial Doppler test could differentiate the risk of future stroke or transient ischemic attack as related to the severity of the defect. «Read the rest of this article»

American Stroke Association says Implanted Cardiac Monitor identifies Stroke risk better than traditional methods

 

American Stroke Association - American Heart AssociationSan Diego, CA – A cardiac monitor about the size of a USB flash drive that’s implanted under the skin was six to seven times more likely to detect atrial fibrillation, an abnormal heart rhythm that’s a risk factor for stroke, according to a science report presented at the American Stroke Association’s International Stroke Conference 2014.

The monitor could help identify the 30 percent of ischemic strokes with no apparent cause.  Ischemic strokes are caused by a clot in a blood vessel in or near the brain. «Read the rest of this article»

American Stroke Association says new stroke outcome measures don’t consider stroke severity

 

American Stroke Association - American Heart AssociationSan Diego, CA - New measures that look at the quality of care provided by hospitals to stroke patients may wind up negatively affecting stroke care, the American Heart Association/American Stroke Association said in a statement.

The stroke outcome measures, which profile hospital performance for Medicare and Medicaid beneficiaries, look at whether patients die or were readmitted to the hospital within 30 days. But they do not consider the stroke’s severity, even though that determination is essential to outcomes, said the AHA.

Hospitals caring for stroke patients should use a consistent standardized risk adjustment model.  (American Heart Association)

American Stroke Association says Cocaine greatly increases Stroke Risk within 24 hours of use

 

American Stroke Association - American Heart AssociationSan Diego, CACocaine greatly increases stroke risk in young adults within 24 hours of use, much more than other risk factors according to research presented at the American Stroke Association’s International Stroke Conference 2014.

Cocaine users were six to seven times more likely to suffer an ischemic stroke within 24 hours of using the drug, and the effect existed across different ethnicities, researchers wrote.
