Dr. Ann McKee, director of Boston University's CTE Center, stressed she could not "connect the dots" between the brain disease chronic traumatic encephalopathy and the behavior of the 27-year-old who hanged himself in April while serving life in prison for murder. But McKee said CTE had significantly impacted key parts of Hernandez's brain, including the hippocampus which is associated with memory and the frontal lobe, which is involved in impulse control, judgment and behavior. "We can say collectively, in our collective experience, that individuals with CTE and CTE of this severity have difficulty with impulse control, decision-making, inhibition of impulses or aggression, often emotional volatility and rage behaviors," said McKee, who has studied hundreds of brains from football players, college athletes and even younger players, donated after their deaths. Hernandez hanged himself in prison days after he was acquitted in the 2012 drive-by shootings of two men in Boston and just hours before his former teammates visited the White House to celebrate their latest Super Bowl victory. Prosecutors contended he gunned the two men down after one accidentally spilled a drink on him in a nightclub and then got a tattoo of a handgun and the words "God Forgives" to commemorate the crime. He had been serving a life sentence without parole in the 2013 killing of semi-professional football player Odin Lloyd when he killed himself. Hernandez, who said he was innocent, did not raise CTE in his defense at either trial. CTE, which can only be diagnosed in an autopsy, has been found in former members of the military, football players and boxers and others who suffered repeated head trauma. BU researchers confirmed in September that Hernandez was diagnosed with Stage 3, out of 4, of the disease. But McKee had not publicly discussed her findings until a conference at the university on Thursday. After Hernandez's CTE diagnosis, his attorneys filed a lawsuit against the NFL and football helmet maker Riddell, accusing them of failing to warn Hernandez about the dangers of football. The lawsuit, which seeks damages for Hernandez's young daughter, said he experienced a "chaotic and horrendous existence" because of his disease. While the outside of Hernandez's brain appeared normal, the inside was riddled with CTE, said McKee, who showed images of Hernandez's brain next to those of a typical 27-year-old. In Hernandez's brain, there was evidence of previous small hemorrhages, which is associated with head impacts, she said. Other parts, like the hippocampus, had begun to shrink and large holes were found in his brain's membrane, McKee said. Before Hernandez, the youngest brain they've examined that showed such severe CTE damage was 46 years old, McKee said. "These are very unusual findings to see in an individual of this age," McKee said. "We've never seen this in our 468 brains, except in individuals some 20 years older," she said. Hernandez inherited a genetic profile that may have made him more susceptible to the disease, McKee said. ___ Follow Alanna Durkin Richer @aedurkinricher . Read more of her work here .

Doctor: Hernandez's brain was severely damaged by disease.

question:
Since the vaccine is not available, a discussion of costs is not warranted. The piece does a nice job of presenting the results of the initial report in terms of absolute and relative risk reduction; however, absolute data is not provided for the secondary analyses. To its credit, the story clearly and effectively explained statistical significance as it relates to this research. As stated in previous coverage, the story reiterates that the benefits of the vaccine are modest and additional research is needed. Given that this is a follow-up report focused on newly released data, a discussion of the potential harms of the vaccine is not necessary. This story does an excellent job defining the different types of analyses used to evaluate the outcome data. The story also points out the results of the secondary analyses have been published in a peer-reviewed journal, suggesting the calculations have been checked for accuracy. This story does not engage in disease-mongering. This story does not provide commentary from any independent sources. In this case, a single comment from a biostatistical consultant would have provided helpful perspective. Given the nature of this follow-up story, a discussion on the existing alternatives to HIV prevention may not be warranted. This story makes it known that the vaccine is still in the testing phase and is not yet available. The story makes it clear that researchers have been working on an AIDS vaccine for decades. The story does not appear to be based on a press release.

AIDS Vaccine Is of Modest Help, Fuller Research Says

question:
There's a good reason for that. A devastating 1964 Alaska earthquake the most powerful on record in the United States led to stricter building codes that helped structures withstand the shifting earth Friday. "Congratulations to the people of Alaska for being really prepared for this earthquake," U.S. Geological Survey Geophysicist Paul Caruso said Saturday. "Because a magnitude 7.0 in a city like that, you know, it could have been significantly worse." Gov. Bill Walker said sometimes people, including himself, grouse about stringent building codes. But he's "really glad" they were in place as he only had minor water damage at his home. "Building codes mean something," he said Friday. The quake was centered about 7 miles (12 kilometers) north of Anchorage, which has a population of about 300,000. People ran from their offices or took cover under desks. A 5.7 aftershock arrived within minutes, followed by a series of smaller quakes. The two big back-to-back quakes knocked items off shelves, disrupted power, broke store windows and briefly triggered a tsunami warning for islands and coastal areas south of the city. Walker issued a disaster declaration, and President Donald Trump declared an emergency, allowing the Federal Emergency Management Agency to coordinate disaster relief. There were no reports of deaths or serious injuries. Still, aftershocks Saturday continued to fray nerves, with people worrying about being caught in more massive shakers. "They're disturbing, and I'm not putting anything away that could fall until they calm down," Randall Cavanugh, an Anchorage attorney, said following a restless night at home. "I kept waking up." By mid-morning, there had been about 550 aftershocks, including 11 with magnitudes of 4.5 or greater, Caruso said. The aftershocks should be weaker and less frequent in the coming days, but officials can't say for sure when they'll stop, he said. Anchorage Mayor Ethan Berkowitz said the extent of damage was "relatively small" considering the scale of Friday's earthquake. He also credited building codes for minimizing structure damage. "In terms of a disaster, I think it says more about who we are than what we suffered," he said Saturday at a press briefing, adding that Anchorage was prepared for such an emergency. "People pulled together. We followed the plans that were in place. We looked after one another. And when people around the country and around the world look at this, they're going to say, 'We want to do things in the Anchorage way because Anchorage did this right," Berkowitz said. After the first earthquake, Alaska's largest hospital activated its incident command center, but the trickle of patients into the emergency room at Providence Alaska Medical Center in Anchorage was more like a normal workday and not a mass casualty event. The injuries were described as minor, and there were no patients with life-threatening conditions. "The flow of patients into the emergency department was similar to a typical Monday," hospital spokesman Mikal Canfield said Saturday. "It wasn't a situation where there was a mass rush of people." Roads didn't fare so well, as reports of extensive damage came in. The Alaska Department of Transportation counted about 50 sites with damage, including eight considered major. Most of the damage was to highways north of Anchorage. The agency also was planning to conduct bridge inspections Saturday. Transportation officials said in a release that the aftershocks continue to contribute to settling and additional cracking. Rock falls exacerbated by the aftershocks were causing some problems on the Seward Highway south of Anchorage. Normal operations resumed at Ted Stevens Anchorage International Airport after flight operations were suspended Friday, Transportation Department spokesman Meadow Bailey told The Associated Press. The 800-mile (1,287-kilometer) trans Alaska oil pipeline was shut down for hours while crews were sent to inspect it for damage. Michelle Egan with Alyeska Pipeline Service Co., the pipeline operator, said the line was restarted at 3:30 p.m. Friday. She said there are no obvious signs of damage and no operational impact on the pipeline, whose closest section is 120 miles (193 kilometers) from the epicenter. Anchorage's school system canceled classes through Tuesday while it examined buildings for damage. Alaska's 1964 earthquake, with a 9.2 magnitude, was centered about 75 miles (120 kilometers) east of Anchorage. It and the tsunami it triggered claimed about 130 lives. The state averages 40,000 earthquakes a year, with more large quakes than the 49 other states combined. Southern Alaska has a high risk of earthquakes because the Earth's plates slide past each other under the region, but it is rare for major quakes to strike so close heavily populated areas. ___ Associated Press writers Becky Bohrer in Juneau, Alaska; Dan Joling in Anchorage; Gillian Flaccus in Portland, Oregon; Gene Johnson in Seattle; Jennifer Kelleher, Audrey McAvoy and Caleb Jones in Honolulu; Rachel La Corte in Olympia, Washington; and John Antczak in Los Angeles contributed to this report. ___ Follow Rachel D'Oro at https://twitter.com/rdoro
