— Doctors have reversed brain damage in an Arkansas toddler, who was pulled from a swimming pool without a pulse in February 2016, in what is being described as a first-of-its kind reversal.
Eden Carlson, 2, was not breathing when her mother, Kristal Carlson, found her in the family’s swimming pool in 2016. Carlson said her daughter climbed through a baby gate, past a heavy door and into the pool while Kristal Carlson was showering, WDSU reported. At the time, Eden was supposed to be playing with her older siblings, the news station reported.
Family members said Eden was not breathing and had no pulse when she was found between 10 and 15 minutes after she first got into the water. Her mother immediately performed CPR, family member said, but Eden had gone into cardiac arrest and had no heartbeat for nearly two hours.
She was rushed to a hospital, where doctors were able to revive her. However, family members said her kidneys and liver weren’t working, and her blood pressure was alarmingly low. An MRI showed she had suffered a deep gray matter injury to her brain and cerebral atrophy with gray and white matter loss, according to officials at the Louisiana State University Health Sciences Center New Orleans.
Doctors gave her between two and 48 hours to live, but she survived and, 48 days later, was released from the hospital. At the time of her release, according to WDSU, Eden didn’t respond to commands, couldn’t speak and constantly squirmed.
Shortly after her release, doctors with the LSU Health Sciences Center New Orleans and the University of North Dakota School of Medicine started giving Eden oxygen therapy treatments in an effort to reverse the brain damage in the days before she could travel to New Orleans to undergo treatment in a hyperbaric chamber, according to Newsweek.
Dr. Paul Harch, clinical professor at Louisiana State University, started giving Eden normobaric oxygen therapy, in which patients are treated with oxygen levels that are the same as those found at sea level. For 45 minutes, twice a day, Eden underwent the treatments.
According to a case study published late last month in the journal Medical Gas Research, doctors said Eden became more alert and stopped squirming as a result of the treatment. She started to laugh and had more control over her arms and eyes. Her speech started to improve, although her vocabulary appeared to be diminished.
About 2 1/2 months after Eden nearly drowned, Harch began treating her using a hyperbaric chamber. Eden underwent the treatment for 45 minutes a day, five days a week, and showed “visually apparent” improvement of her symptoms.
After just 10 of the planned 40 hyperbaric chamber sessions, Eden’s mother told doctors that her daughter was “near normal,” according to officials with the LSU Health Sciences Center New Orleans.
Twenty-seven days after her last treatment session, doctors said she had only mild residual injuries. The brain damage seen in the immediate aftermath of her near drowning was nearly entirely reversed.
Harch said in a statement that the “startling” recovery was partially due to Eden’s age and the timing. Doctors were able to intervene “before long-term tissue degeneration,” he said.

Asteroid 2002 AJ129 – which at 0.7 miles is wider than the tallest building in the U.S. (New York's One World Trade Center) stacked on top of itself – is predicted to miss our planet, according to Metro. However, it will pass relatively close in terms of outer space.
NASA classifies any space object surpassing 459 feet wide and passing within 4,660,000 miles of Earth as "hazardous," according to a 2013 report on the space agency's website. There are about 1,000 such known space objects monitored by NASA.
This asteroid is more than eight times wider than the minimum (3,696 feet) and will pass within just over half the minimum distance (2,615,128 miles) to our planet.
For a reference point, the moon orbits Earth at a distance of about 238,855 miles.

BLOOMFIELD HILLS, Mich. — The fireball lit up the sky just after 8 p.m. Tuesday.
The dashboard cam video was shared by Mike Austin as he was driving north on I-75 near Bloomfield Hills, north of Detroit, Michigan.
The fireball also was seen from northwest Ohio and southwest Ontario, Canada.
It is not known whether the meteorite dissipated in the atmosphere or made it to the ground or into Lake Michigan.

— The holiday season is officially over, and many are now looking at their New Year’s resolutions, which may include maintaining a healthier lifestyle.
To get a head start, some are participating in Dry January, a month-long break from alcohol. But how effective is it?
Researchers from the University of Sussex conducted a study, published in Health Psychology, to find out.
They examined more than 850 individuals who gave Dry January a try. They then followed up with a questionnaire one month later and another six months later.
After analyzing the results, they found that after six months, participants said they drank less and were not getting drunk as much.
In fact, 72 percent of the subjects had maintained lower levels of harmful drinking and 4 percent were still not drinking after six months.
After just one month, about 62 percent reported having better sleep, 62 percent said they had more energy and 49 percent experienced weight loss.
The changes were also seen for those who did not make it to the end of the challenge. “Even if participants took part but didn’t successfully complete the 31 days, it generally led to a significant decrease across all the measures of alcohol intake,” Richard de Visser said in a statement.
The scientists believe their findings prove the challenge can be used to help reduce drinking long-term, added Emily Robinson, director of campaigns at Alcohol Concern, a U.K. charity to combat alcohol harm.
“This research,” she said, “is the proof of how, with the help, advice and support we offer throughout the month, our model can really change behaviour and reduce drinking.”

— Memory loss and confusion are common symptoms of dementia. Now scientists are linking canola oil to the disease in a new report.
Researchers from Temple University recently conducted an experiment, published in Scientific Reports, to determine how the common cooking oil may have an effect on the brain.
To do so, they examined mice that were six months old, dividing them into two groups. One was fed a normal diet, while the other had “a diet supplemented with the equivalent of about two tablespoons of canola oil,” the authors explained.
After observing the animals for 12 months, they weighed them. They found that the mice on the canola oil diet weighed significantly more than those on a regular diet.
They then assessed their working memory, short-term memory and learning ability by administering maze tests. They discovered the mice that had consumed canola oil suffered damage to their working memory. The canola oil-treated mice had reduced levels of amyloid beta 1-40, a protein that serves a beneficial role in the brain.
“As a result of decreased amyloid beta 1-40, animals on the canola oil diet further showed increased formation of amyloid plaques in the brain, with neurons engulfed in amyloid beta 1-42,” the authors said. “The damage was accompanied by a significant decrease in the number of contacts between neurons, indicative of extensive synapse injury. Synapses, the areas where neurons come into contact with one another, play a central role in memory formation and retrieval.”
Their findings suggest canola oil is not beneficial to the brain, especially when it is consumed over long periods of time. Researchers now hope to further their studies to find out exactly how much canola oil can produce changes in the brain and if it can be linked to Alzheimer’s disease.
“Even though canola oil is a vegetable oil, we need to be careful before we say that it is healthy,” lead researcher Domenico Pratico said. “Based on the evidence from this study, canola oil should not be thought of as being equivalent to oils with proven health benefits.”
