What is PANDAS, the disorder some say can cause extreme behavioral changes in kids?

Health
Alexia Baier was an eager-to-learn, 4-year-old girl beginning pre-K in a suburb outside of Chicago. She thrived academically -- counting, painting and playing with other children. But five months after starting pre-K, she was infected with a bacteria that several millions of people get every year, according to the Centers for Disease Control and Prevention. The bacteria, group A strep, caused Alexia to get strep throat, a condition children usually recover from easily with treatment. After 10 days of antibiotics, the infection disappeared but so did Alexia's bubbly personality. Within two days after completing antibiotics, Alexia began showing behavioral changes at home and eventually at school. She suddenly became defiant and explosive. "It was a lot of screaming, a lot of hitting and...
Genetic changes in blood may predict leukemia diagnosis

Genetic changes in blood may predict leukemia diagnosis

Health
July 9 (UPI) -- Studying genetic changes in blood, researchers have found a way to identify people at high risk of developing acute myeloid leukemia several years before diagnosis. In the study, published Monday in the journal Nature, researchers from around the world found changes in DNA can reveal the roots of AML in healthy people an average of 6.3 years before symptoms. The researchers hope that methods of reducing the likelihood of developing the cancer will arise with earlier detection and monitoring of those at risk of AML. "Acute myeloid leukemia often appears very suddenly in patients, so we were surprised to discover that its origins are generally detectable more than five years before the disease develops," first author Dr Grace Collord, of the Wellcome Sanger Institute and Un...
Inbred animals struggle to adapt to environmental changes

Inbred animals struggle to adapt to environmental changes

Science
June 29 (UPI) -- Inbreeding makes animals more vulnerable to environmental changes, new research shows. When scientists inbred beetles, they found the insects made poorer decisions as environmental factors changed. In the lab, researchers observed the behavior of dozens of female burying beetles as they reared their young on the carcass of a dead mouse. In the middle of the experiment, scientists altered the beetles' food source, swapping out the first mouse carcass for a second smaller mouse carcass. Beetles that were inbred failed to adapt, raising too many young despite the smaller food source. The control group, non-inbred beetles, culled portions of their larvae clutch, as the beetles do in the wild, ensuring all of their young are sufficiently fed. The offspring of inbred beetles w...

Changes to tiny blood vessels may help diagnose traumatic brain injuries

Changes to tiny blood vessels may help diagnose traumatic brain injuries

Health
April 30 (UPI) -- By finding changes to tiny blood vessels in the brains of people with traumatic injuries, researchers believe medical personnel could be able to make more precise diagnosis and treatment decisions.Researchers found that changes in the blood vessels may be linked to a range of cognitive symptoms after a traumatic brain injury, or TBI. The research, which was led by the University of Pennsylvania, was presented Friday at the American Academy of Neurology Annual Meeting and has not yet been published."The relationship between microvascular and structural injury in chronic TBI has been recognized for years, but underappreciated," Dr. Ramon Diaz-Arrastia, director of the Traumatic Brain Injury Clinical Research Center at the Perelman School of Medicine at Pennsylvania, said in...
