Lack of Sleep Can Increase Stroke Risk

WASHINGTON: Habitually sleeping less than 6 hours a night significantly increases the risk of stroke symptoms among middle-age to older adults, according to a research presented at the SLEEP 2012 conference.

The study, which followed about 5,600 people for about three years, concluded that poor sleep can undermine all the other things we do, China’s Xinhua news agency said.

The participants had no history of stroke, transient ischemic attack, stroke symptoms or high risk for obstructive sleep apnea at the start of the study.

Researchers from the University of Alabama at Birmingham recorded the first stroke symptoms, along with demographic information, stroke risk factors, depression symptoms and various health behaviours.

After adjusting for body-mass index, they found a strong association with daily sleep periods of less than six hours and a greater incidence of stroke symptoms for middle-age to older adults, even beyond other risk factors.

“We speculate that short sleep duration is a precursor to other traditional stroke risk factors, and once these traditional stroke risk factors are present, then perhaps they become stronger risk factors than sleep duration alone,” lead author Megan Ruiter said in a statement.

Further research may support the results, providing a strong argument for increasing public awareness of the impact of sleep as a risk factor for stroke symptoms, especially among persons who appear to have few or no traditional risk factors for stroke, she said. – Bernama

Apple Founder Steve Jobs, 56, Dies of Pancreatic Cancer

The Apple chairman and former Chief Executive Officer Steve Jobs passed away on Wednesday after a long struggle with pancreatic cancer. He was 56 years old, reported China’s Xinhua news agency. Steve’s brilliance, passion and energy were the source of countless innovations that enrich and improve all of our lives,” Apple said in a statement.

He died just a day after Apple unveiled its latest bauble, the iPhone 4S, at an event that Jobs usually presided over with singular showmanship. It was the first such presentation in years where Jobs did not take the stage in his signature jeans and black turtleneck.

“Steve’s brilliance, passion and energy were the source of countless innovations that enrich and improve all of our lives,” Apple said in a statement. “His greatest love was for his wife, Laurene, and his family. Our hearts go out to them and to all who were touched by his extraordinary gifts.”

Jobs stepped away as CEO of the company he helped turn into a tech titan in August, citing his failing health. He was replaced by Tim Cook, but continued to serve as the company’s chairman.

Apple’s homepage currently bears an image of the company’s co-founder, top, and advised those wishing to send condolences to email them to

His former rival, Microsoft Chairman Bill Gates, paid tribute to Apple’s creative visionary, calling him a colleague, a competitor and a friend.

“The world rarely sees someone who has had the profound impact Steve has had, the effects of which will be felt for many generations to come,” Gates said in a statement. “For those of us lucky enough to get to work with him, it’s been an insanely great honor. I will miss Steve immensely.”

Apple has also put up the following website in memory. They’re asking for “thoughts, memories, and condolences” to be shared by way of this email address:

Jobs announced to his employees in 2004 that he had been diagnosed with a tumor in his pancreas, eventually undergoing a pancreaticoduodenectomy that seemed to have removed the tumor. Health concerns continued to plague him, though; in 2009, Jobs underwent a liver transplant, and took a medical leave of absence in January to focus on his heath.

In a 2005 commencement speech at Stanford, Jobs spoke movingly of his decision to drop out of college and his 1984 ouster from Apple, before delving into his cancer diagnosis. Although pancreatic cancer has a high mortality rate, Jobs said he took the news in stride.

Jobs is survived by his wife, Laurene Powell, their three children Reed Paul, Erin Sienna and Eve, and a daughter, Lisa Brennan-Jobs, from a previous relationship.
