Munich: Young men who die suddenly after being arrested by the police may be victims of a new syndrome similar to one that kills some wild animals when they are captured, Spanish researchers said on Tuesday.
Manuel Martinez Selles of Madrid's Hospital Gregorio Maranon reached the conclusion after investigating 60 cases of sudden unexplained deaths in Spain following police detention.
In one third of the cases, death occurred at the point of arrest, while in the remainder death was within 24 hours, Selles told the annual meeting of the European Society of Cardiology.
All but one of the casualties were male and their average age was just 33 years, with no previous history of cardiovascular disease.
"Something unusual is going on," Sells said.
Comment: Taser syndrome?
Physical exercise may help improve memory in older people and delay the onset of dementia, a new study published in the Journal of the American Medical Association shows.
A University of Western Australia study has found that walking for 50 minutes three times a week can lessen memory problems for older people. The study involved 170 volunteers aged 50 and over who reported some memory trouble but who did not have dementia.
The number of people with Alzheimer's disease, the most common form of dementia, is predicted to quadruple worldwide over the next half century. Alzheimer's is a terminal and degenerative disease for which there is known no cure. In its common form, it affects people over 65 years old. The most commonly symptom is memory loss, as well as the difficulty to remember recently learned facts. Studies have shown that 700,000 in the UK live with dementia and the number may increase over the next two decades.
Think back to when you slipped on the ice or in the shower: the ground rushing up, your feet shooting out, terror building even as your mind is working a mile a second to plot a soft landing.
Hundreds of Belgian children underwent thyroid gland tests on their first day back at school after a radioactive leak in the vicinity of Charleroi city a week ago, the government said Monday.
Compared to mothers who don't spank their children, mothers who've spanked their child in the past year are three times more likely to use harsher forms of punishment.
That's the conclusion of a new study from the Injury Prevention Research Center at the University of North Carolina at Chapel Hill.
About one in five ayurvedic medicine products purchased on the Internet contain significant levels of lead, mercury or arsenic, a new study finds.
The researchers found that products manufactured in the United States were even more likely to contain the metals than those made in India, where the ayurvedic approach was first developed centuries ago. Furthermore, 75 percent of the products containing lead, mercury or arsenic advertised that they were manufactured using "Good Manufacturing Practices," which is a U.S. Food and Drug Administration (FDA) regulation meant to ensure quality.
Blockbusters are expiring, pipelines are emptying and watchdogs are growling
The pharmaceutical industry is under siege with the looming end of blockbuster drugs, imminent patent expiries on top-selling medicines and government pressure to lower prices amid accusations of profiteering.
GlaxoSmithKline's new boss, Andrew Witty, has likened discovering a blockbuster - with annual revenues of at least $1bn - to finding a needle in a haystack. Many of the big-selling medicines launched in the 1990s are about to come off patent, allowing generic drugmakers to make cheaper versions. Only four of the 10 major companies have enough products in their pipeline to plug the looming revenue shortfall.
Reducing levels of uric acid in blood lowered blood pressure to normal in most teens in a study designed to investigate a possible link between blood pressure and the chemical, a waste product of the body's normal metabolism, said researchers at Baylor College of Medicine in a report that appears in the current issue of the Journal of the American Medical Association.
"If you reduce uric acid, at least in some patients, you may be able to reduce blood pressure," said Dr. Daniel Feig, associate professor of pediatrics-renal at BCM and chief of the pediatric hypertension clinics at Texas Children's Hospital. "This could be one way people develop hypertension and may allow us to develop new therapies."
Understanding how people develop high blood pressure gives scientists new tools for understanding the disorder and developing drugs to prevent and treat it.
Finnish scientists have identified genes that may predispose to anxiety disorders. Research conducted under the supervision of Academy Research Fellow Iiris Hovatta have focused on genes that influence human behaviour, and some of the studied genes show a statistical association with specific anxiety disorders. The work is carried out as part of the Academy of Finland Research Programme on Neuroscience (NEURO).
You might call Maarten van der Weijden the anti-Lance Armstrong. Last week, the Dutch Olympic long-distance swimming champion and cancer survivor told the British newspaper The Telegraph that he didn't want to be compared to the American cycling star.
"Armstrong says that positive thinking and doing a lot of sports can save you. I don't agree," said van der Weijden. "I even think it's dangerous because it implies that if you are not a positive thinker all the time you lose ... The doctors saved me. I am just lucky."
