Ohio Man Declared Dead, Then Revived
An Ohio man who was declared dead but came back to life is
resting at home and plans to return to work on Monday.
On Aug. 5, doctors at Kettering Medical Center spent 45 minutes
trying to revive Anthony Yale after the 37-year-old diesel
mechanic's heart stopping beating, but then decided to declare him
But moments after the man's 17-year-old son Lawrence shouted at
his father, "Dad, you're not going to die today," Anthony's heart
monitor started showing some activity. It wasn't a regular heart
beat, but tiny electrical signals that appeared on the heart
monitor once or twice a minute.
"When I looked at the electrical activity, I was surprised," cardiologist Dr. Raja Nazir told ABC News. "I thought we'd better make another effort to revive him."
As the medical team worked on him, Yahle's heart rate slowly
began to increase. Nazir isn't sure exactly how long Yahle was
"dead," before his son told his father he couldn't die that
"I'm calling it a miracle because I've never seen anything like it," Nazir told ABC News.
Yahle was later transferred to Ohio State University and
returned home on Aug. 10 with a heart defibrillator. Doctors may do
a heart biopsy to try to determine what happened to him.
'Super-Agers' May Provide Clues About Healthy Brain Aging
Researchers are studying so-called "super agers" in the hope of
findings ways to protect others from age-related memory loss.
Super-agers are people in their 80s and 90s who have brains and
memories that seem far younger. Only 10 percent of 400 people
who've applied to take part in the research have met the criteria
for being a super-ager, the
So far, researchers have found that the brains of super-agers
have unusually low amounts of age-related plaques and more mass
related to attention and memory.
"We're living long but we're not necessarily living well in our older years and so we hope that the SuperAging study can find factors that are modifiable and that we'll be able to use those to help people live long and live well," study leader Emily Rogalski, a neuroscientist at Northwestern University's cognitive neurology and Alzheimer's disease center in Chicago, told the AP.
Another H7 Bird Flu Virus Found in Chickens in China
Another potentially dangerous H7-type virus has been detected in
chickens in China, say scientists studying the H7N9 bird flu virus
that's killed more than 40 people since March.
The researchers said the virus, called H7N7, was able to infect
mammals in a lab experiment and warned that H7 viruses "may pose
threats beyond the current outbreak,"
"The continuing prevalence of H7 viruses in poultry could lead to the generation of highly pathogenic variants and further sporadic human infections," the team wrote in a study published in the journal Nature.
H7N7 spreads easily in birds. It killed one person and caused
more than 80 cases of mild disease during a 2003 outbreak in the
"If (we) let this H7N7 continue circulating in chickens, I am sure that human infection cases will occur," study co-author Yi Guan, from the University of Hong Kong, told AFPby email. "This virus could cause more severe infection than... H7N9, based on our animal experiment."
Middle East Respiratory Virus Found in Bat
A deadly respiratory virus responsible for an ongoing outbreak
in the Middle East has been found in a bat in Saudi Arabia,
The Middle East respiratory syndrome coronavirus (MERS-CoV) was
found in an Egyptian tomb bat captured close to the home of the
first known human victim of the virus,
But the scientists don't believe that bats are responsible for
passing the virus to people. Instead, they believe the virus
spreads from bats to other animals before being transmitted to
people, according to a paper in the journal
Emerging Infectious Diseases.
Another recently published paper suggests that this intermediary
animal could be the dromedary camel,
MERS-CoV first appear in the Middle East last year. So far,
there have been 94 confirmed human cases and 47 deaths.
Americans Warned About Cholera Risk in Cuba
American travelers to Cuba should avoid street food and under-
or uncooked dishes such as ceviche to reduce their risk of
contracting cholera, says a U.S. government advisory issued
Several foreigners -- an Italian, two Venezuelans and two
Chileans -- who visited Cuba were sickened by cholera in late July
and early August, according to the Pan American Health
Last summer, Cuban officials acknowledged a rare outbreak of the
waterborne disease. This January, authorities announced 51 new
cases of cholera in Havana, but have provided no updates since
Cholera can cause death from severe dehydration but is treatable
if detected in time, the
