There was a time when gluten, a mixture of proteins found in wheat, rye and barley, was something of a foreign term. Not many people had heard of it, and the few who needed to avoid it found meals to be extremely challenging.Today, I hear the word "gluten" on a daily basis, but mostly as a food component to be avoided at all costs. In fact, according to late-night host Jimmy Kimmel, it seems that "in Los Angeles, gluten is comparable to Satanism." But is banning gluten from your diet really a wise health decision?"That's the ,000 question that everyone is asking," said Shelley Case, a registered dietitian, expert on the gluten-free diet and author of "Gluten Free: The Definitive Resource Guide." "The answer is, not everyone benefits from going gluten-free, despite the fact that celebrities and athletes say it will cure anything that ails you." 871

TIJUANA, Mexico (AP) — More buses of exhausted people in a caravan of Central American asylum seekers reached the U.S. border Thursday as the city of Tijuana converted a municipal gymnasium into a temporary shelter and the migrants came to grips with the reality that they will be on the Mexican side of the frontier for an extended stay.With U.S. border inspectors at the main crossing into San Diego processing only about 100 asylum claims a day, it could take weeks if not months to process the thousands in the caravan that departed from San Pedro Sula, Honduras, more than a month ago.Tijuana's robust network of shelters was already stretched to the limit, having squeezed in double their capacity or more as families slept on the floor on mats, forcing the city to open the gymnasium for up to 360 people on Wednesday. A gated outdoor courtyard can accommodate hundreds more.The city's thriving factories are always looking for workers, and several thousand Haitian migrants who were turned away at the U.S. border have found jobs and settled here in the last two years, but the prospect of thousands more destitute Central Americans has posed new challenges.Delia Avila, director of Tijuana's family services department, who is helping spearhead the city's response, said migrants who can arrange legal status in Mexico are welcome to stay."Tijuana is a land of migrants. Tijuana is a land that has known what it is to embrace thousands of co-nationals and also people from other countries," Avila said.Mexican law enforcement was out in force in a city that is suffering an all-time-high homicide rate. A group of about 50 migrants, mostly women and children, walked through downtown streets Thursday from the city shelter to a breakfast hall under police escort.As buses from western and central Mexico trickled in overnight and into the morning, families camped inside the bus terminal and waited for word on where they could find a safe place to sleep. One shelter designed for 45 women and children was housing 100; another designed for 100 had nearly 200.Many endured the evening chill to sleep at an oceanfront park with a view of San Diego office towers and heavily armed U.S. Border Patrol agents on the other side of a steel-bollard fence.Oscar Zapata, 31, reached the Tijuana bus station at 2 a.m. from Guadalajara with his wife and their three children, ages 4, 5 and 12, and headed to the breakfast hall, where migrants were served free beef and potatoes.Back home in La Ceiba, Honduras, he had been selling pirated CDs and DVDs in the street when two gangs demanded "protection" money; he had already seen a colleague gunned down on a street corner because he couldn't pay. He said gangs called him and his wife on their cellphones and showed up at their house, threatening to kidnap his daughter and force her into prostitution if he didn't pay.When he heard about the caravan on the TV news last month, he didn't think twice."It was the opportunity to get out," Zapata said, waiting in line for breakfast.Zapata said he hopes to join a brother in Los Angeles but has not yet decided on his next move. Like many others, he planned to wait in Tijuana for others in the caravan to arrive and gather more information before seeking asylum in the United States.Byron Jose Blandino, a 27-year-old bricklayer from Nicaragua who slept in the converted gymnasium, said he wanted to request asylum but not until he could speak with someone well-versed in U.S. law and asylum procedures."The first thing is to wait," Blandino said. "I do not want to break the laws of any country. If I could enter in a peaceful manner, that would be good.To claim asylum in San Diego, migrants enter their names in a tattered notebook held together by duct tape and managed by the migrants in a plaza outside the entry to the main border crossing.On Thursday, migrants who registered six weeks ago were getting their names called. The waiting list has grown to more than 3,000 names and stands to become much longer with the caravans.Tijuana officials said there were about 800 migrants from the caravan in the city Wednesday. The latest arrivals appeared to push the total above 1,000.The migrants have met some resistance from local residents, about 100 of whom confronted a similar-size group of Central Americans who were camped out by the U.S. border fence Wednesday night."You're not welcome" and "Get out!" the locals said, marching up to the group.Police kept the two sides apart.Vladimir Cruz, a migrant from El Salvador, shook his head and said: "These people are the racists, because 95 percent of people here support us.""It is just this little group. ... They are uncomfortable because we're here," Cruz said.Playas de Tijuana, as the area is known, is an upper-middle-class enclave, and residents appeared worried about crime and sanitation. One protester shouted, "This isn't about discrimination, it is about safety!"There are real questions about how the city of more than 1.6 million will manage to handle the migrant caravans working their way through Mexico, which may total 10,000 people in all."No city in the world is prepared to receive this number of migrants," said Tijuana social development director Mario Osuna, adding that the city hopes Mexico's federal government "will start legalizing these people immediately" so they can get jobs and earn a living.Dozens of gay and transgender migrants in the caravan were already lining up Thursday to submit asylum claims, though it was unclear how soon they would be able to do so.The caravan has fragmented somewhat in recent days in a final push to the border, with some migrants moving rapidly in buses and others falling behind.On Thursday, hundreds were stranded for most of the day at a gas station in Navojoa, some 750 miles (1,200 kilometers) from Tijuana."We were dropped here at midnight ... in the middle of nowhere, where supposedly some buses were going to come pick us up, but nothing," Alejandra Grisel Rodriguez of Honduras told The Associated Press by phone. "We are without water, without food."After about 12 hours seven buses began arriving to collect the migrants, Rodriguez said, but they quickly filled up."We would need at least 40 or 50," she said.Jesus Edmundo Valdez, coordinator of firefighters and civil defense in Navojoa, said Wednesday that authorities were providing food, water and medical attention to migrants there. His phone rang unanswered Thursday.Mexico has offered refuge, asylum and work visas to the migrants, and its government said this week that 2,697 temporary visas had been issued to individuals and families to cover them during the 45-day application process for more permanent status. Some 533 migrants had requested a voluntary return to their countries, the government said.___Associated Press writer Maria Verza contributed from Culiacan, Mexico. 6880

This week, more than 150 people, including author J.K. Rowling and other academics, journalists and writers, signed on to an open letter published in Harper’s Magazine calling for an end to the so-called cancel culture.The piece, “A Letter on Justice and Open Debate” argues that being quick to cancel someone or something could lead to a silencing of viewpoints and less reforms.“The free exchange of information and ideas, the lifeblood of a liberal society, is daily becoming more constricted. While we have come to expect this on the radical right, censoriousness is also spreading more widely in our culture: an intolerance of opposing views, a vogue for public shaming and ostracism, and the tendency to dissolve complex policy issues in a blinding moral certainty,” the letter reads.The letter is in response to a growing trend of canceling people and entities over past or present statements.What is cancel culture? It refers to removing support for a public figure or leader in response to that person’s objectionable behavior or opinions. Removing support can include boycotts, canceling appearances or performances, refusing to promote that person’s work, etc.The phrase cancel culture has come into being the last few years to talk about actions being taken during movements like #MeToo, #BlackLivesMatter and other social justice conversations that are demanding greater accountability from public figures and a reckoning with their past comments or behaviors. Examples include big names like Bill Cosby, Harvey Weinstein, and R Kelly.Last month, Ivanka Trump, President Trump’s daughter and presidential advisor, tweeted that she believed a canceling of a commencement speech at a school at Wichita State University was part of a cancel culture. 1767

Their youthful brains were developing normally, with no signs of developmental, psychological or neurological problems. None had ever had a concussion. But by the end of a single football season, 24 children between the ages of 9 and 18 who had more frequent impacts to the head showed signs of damage to brain development, new research says."Repetitive head impact exposure may have a cumulative effect in the rapidly developing brains of youth and high school football players," said study co-author Gowtham Krishnan Murugesan, a radiology research assistant at UT Southwestern Medical Center in Dallas, adding that the results mirror other recent findings.The study outfitted 60 youth and high school football players who had no history of head trauma or developmental issues with a head impact telemetry system that measures the magnitude, location and direction of impacts to the head. The researchers were not looking at whether the impact resulted in a concussion, only that impact occurred.The children were sorted into two categories: high cumulative head impact players (24) and low cumulative head impact players (36).Before beginning to play, each child had a resting state functional scan, known as an fMRI; the scans were repeated at the end of football season. The researchers were trying to see how exposure to repetitive hits affects the normal "pruning" process in the brain that occurs during adolescence."Pruning is an essential part of brain development," Murugesan said, comparing the process to how a tree needs to have dead or unneeded branches cut to keep it healthy and allow it to grow."Disruption in normal pruning has been shown to be related to weaker connections between different parts of the brain," he said.After comparing the functional MRI results to the player's level of impact, the researchers found that youth in the high-impact group had damage to their brains' pruning process after one season."Our study has found a significant decrease in gray matter pruning in the frontal default mode network, which is involved in higher cognitive functions, such as the planning and controlling of social behaviors, " Murugesan said.Although the "teenage years are a critical time for brain development, brain remodeling or synaptic pruning, this was a short-term study and did not follow the players longitudinally over several years. We don't really know the full application," said Dr. Julian Bailes, director of neurosurgery and co-director of the NorthShore University HealthSystem Neurological Institute, who was not involved in the research.Weill Cornell neurologist Dr. Richard Isaacson, who was also not involved in the study, called the research "early" and said the results don't necessarily "translate to a clinical or cognitive outcome." More research is needed to see whether the decline in brain pruning permanently affected the child's cognitive function or whether the brain's natural plasticity allowed it to repair itself."I would call this a pilot study," Isaacson said. "The call to action would be that we need more robust longitudinal studies with a pre- and a post-assessment of more than brain imaging. The study should also measure cognitive and neurological function and look for changes."As we learn more about the issue, Isaacson said, parents should do everything they can to limit contact in sports, "especially in practice before games, where studies show the majority of contact occurs." 3464

There are now 286 cases of possible and confirmed acute flaccid myelitis in the United States this year, according to the US Centers for Disease Control and Prevention.That includes 116 confirmed cases of the rare polio-like illness, also known as AFM, that leads to sudden onset of paralysis. That's 10 more confirmed cases than the agency reported a week ago. An additional 170 possible cases of AFM are under investigation.More than 90% of the 440 patients with AFM since 2014 have been children younger than age 4. Most of the children with confirmed cases experienced a viral illness with symptoms including fever and cough about three to 10 days before the onset of paralysis, the CDC said this month. 715
