New Astrocytes Play Unexpected Role In Healing After Brain Injury
The production of a certain kind of brain cell that had been considered an impediment to healing may actually be needed to staunch bleeding and promote repair after a stroke or head trauma, researchers at Duke Medicine report. These cells, known as astrocytes, can be produced from stem cells in the brain after injury. They migrate to the site of damage where they are much more effective in promoting recovery than previously thought. This insight from studies in mice, reported online in the journal Nature, may help researchers develop treatments that foster brain repair...

Eggs, Also, May Raise Heart Risk Via Gut Bacteria
Yet another study, by the same US research team, links raised risk of heart attack and stroke to the action of gut bacteria on certain compounds contained in digested food. This time the link is to a compound found in eggs: lecithin. Earlier this month, researchers reported in Nature Medicine how they found L-carnitine, a compound found in red meat and added to energy drinks, can increase heart risk because gut bacteria digest it to produce trimethylamine-N-oxide (TMAO), a metabolite already suspected of helping to clog up arteries...

Association Between Demanding Physical Work And Increased Risk Of Cardiovascular Disease
Two studies presented at this year's EuroPRevent 2013 congress suggest that demanding physical work has a detrimental effect on an individual's risk of coronary heart disease. The first was a case-control study described by Dr Demosthenes Panagiotakos, Associate Professor of Biostatistics-Epidemiology at Harokopio University, Athens, which evaluated occupation in 250 consecutive patients with a first stroke, 250 with a first acute coronary event and 500 equally matched controls...

In Countries Of Varying Income Levels, Adoption Of Healthy Lifestyle Low By Individuals With Cardiovascular Disease
Among patients with a coronary heart disease or stroke event from countries with varying income levels, the prevalence of healthy lifestyle behaviors (such as regular physical activity, eating a healthy diet, and not smoking) was low, with even lower levels in poorer countries, according to a study in the April 17 issue of JAMA. "Observational data indicate that following an acute coronary syndrome, those who adhere to a healthier lifestyle have a lower risk of recurrent events...

Acorda's MS Drug Ampyra Helps Stroke Patients Walk
An Acorda Therapeutics drug, Ampyra (dalfampridine), which helps people with multiple sclerosis walk, also helps stroke patients who cannot walk, the company announced. In a proof-of- concept Phase II study, Ampyra (dalfampridine extended release 10mg tablets) significantly improved walking in patients with post-stroke deficits. Post-stroke deficits include impaired walking, motor and sensory function, as well as manual dexterity - collectively known as chronic neurological deficits. These deficits often persist in stroke victims. Ron Cohen, M.D...

Study Finds Post-Stroke Aphasia Recovery Impeded By Shift Of Language Function To Right Hemisphere
In a study designed to differentiate why some stroke patients recover from aphasia and others do not, investigators have found that a compensatory reorganization of language function to right hemispheric brain regions bodes poorly for language recovery. Patients who recovered from aphasia showed a return to normal left-hemispheric language activation patterns. These results, which may open up new rehabilitation strategies, are available in the current issue of Restorative Neurology and Neuroscience...

Less Salt and More Potassium Reduce Risk Of Stroke
Less salt and more potassium in a person's diet can lower blood pressure and the risk of stroke. Making these simple changes can save millions of lives each year, according to new studies published in the British Medical Journal (BMJ). Scientists have known that reducing the amount of salt people eat can lower their blood pressure, which ultimately reduces the risk of heart disease and stroke. A previous study in the same journal showed that high salt intake is linked to a significantly increased risk of stroke and cardiovascular disease...

Reducing Salt And Increasing Potassium Will Have Major Global Health Benefits
Results have helped develop first WHO guidelines on potassium intake Cutting down on salt and, at the same time, increasing levels of potassium in our diet will have major health and cost benefits across the world, according to studies published on bmj.com today. Such a strategy will save millions of lives every year from heart disease and stroke, say experts. Much evidence shows that reducing salt intake lowers blood pressure and thereby reduces the risk of stroke and heart disease...

For-Profit Hospitals Outscore Public/Non-Profit On Performance Measures
For-profit hospitals are outperforming other hospitals when treating stroke, heart attack and pneumonia patients in emergency departments and, thus, will be more likely to receive bonuses under Medicare's new payment rules, according to a new Northwestern Medicine® study. Though nonprofit and public hospitals are lagging behind in performance, many are making noticeable improvements and also many will be eligible for bonuses, too...

Heart And Stroke Risk Tests Can Predict Dementia Risk
Evaluating a person's future risk of heart disease and stroke may be a better predictor of mental decline than a dementia risk test. The finding came from new research published in the journal Neurology, the medical journal of the American Academy of Neurology. "This is the first study that compares these risk scores with a dementia risk score to study decline in cognitive abilities 10 years later," said Sara Kaffashian, PhD, with the French National Institute of Health and Medical Research (INSERM) in Paris, France...

Does Surgical Menopause Prime The Brain For Stroke, Alzheimer's?
Women who abruptly and prematurely lose estrogen from surgical menopause have a two-fold increase in cognitive decline and dementia. "This is what the clinical studies indicate and our animal studies looking at the underlying mechanisms back this up," said Brann, corresponding author of the study in the journal Brain. "We wanted to find out why that is occurring. We suspect it's due to the premature loss of estrogen...

In Certified Primary Stroke Centers, Acute Stroke Therapy Used 3 Times More Frequently
Certified Primary Stroke Centers are three times more likely to administer clot-busting treatment for strokes than non-certified centers, reports a new study by researchers in the Perelman School of Medicine at the University of Pennsylvania. The study, published in the Journal of the American Heart Association, looked at a wide sample of hospitals across the United States, and provides insight into practice across the US health care system as experts examine ways to increase the use of this important therapy...

Heart Defect Procedure Reduces Stroke By 73%
A procedure to close a heart defect that most people are born with can decrease the risk of recurrent stroke by 73 percent, according to new data published in the New England Journal of Medicine. The findings came from an eight year study called the RESPECT trial (Randomized Evaluation of recurrent Stroke comparing PFO closure to Established Current standard of care Treatment). It was made to test the superiority of the AMPLATZER PFO device in the treatment of cryptogenic stroke patients compared with current medical management...

Who Is Taking Aspirin To Prevent Heart Attack Or Stroke? First Of Its Kind Study In Canada
A new study out of the Faculty of Medicine & Dentistry shows a large population of healthy people are taking Aspirin to prevent cardiovascular disease, despite the fact that new literature shows it isn't as beneficial as once thought. Olga Szafran and Mike Kolber, in the Department of Family Medicine at the University of Alberta, surveyed patients over the age of 50 at two clinics in Alberta. They found that more than 40 per cent of people who don't suffer from cardiovascular disease are popping pills daily to prevent a heart attack or stroke - a practice called primary prevention...

Astrocyte Signaling Sheds Light On Stroke Research
New research published in The Journal of Neuroscience suggests that modifying signals sent by astrocytes, our star-shaped brain cells, may help to limit the spread of damage after an ischemic brain stroke. The study in mice, by neuroscientists at Tufts University School of Medicine, determined that astrocytes play a critical role in the spread of damage following stroke. The National Heart Foundation reports that ischemic strokes account for 87% of strokes in the United States...
