LAKELAND, Fla. -- A Florida bus attendant has been arrested for child abuse, according to the Polk County Sheriff's Office. Deputies say Brenda Nelson, 65, of Polk City has been charged with one count of child abuse for reportedly striking a special needs child on a school bus. On Wednesday, November 8 at about 4:23 p.m. the Transportation Safety Specialist told deputies a citizen complaint was received from a witness who reported she saw a bus attendant strike a female student on the head. The witness was not riding the bus. The witness advised officials that the incident took place on Wednesday, November 8 at approximately 3:58 p.m. The bus transports special needs children from the Doris Sanders Learning Center in Lakeland to their homes throughout Polk County, according to the Sheriff's Office. Deputies reviewed video footage that shows Nelson attempting to help a special needs child off of the bus. In the video, deputies say the victim was strapped to her seat by a "Houdini Harness" which is designed to significantly restrict her movement and mobility. At about 3:58 p.m., Brenda Nelson is seen on video walking by the victim and hitting her on the top of her head with an open left hand and saying "I'm gonna slap that tongue out of your mouth when I get up there."Two minutes later, the video shows Nelson walk behind the victim's seat, grab the victim by her hair and violently shake the victim's head back and forth and to the side, approximately four times. Deputies say after shaking the victim's head, Nelson was seen pulling something behind the victim's seat in an effort to tighten her harness. The victim attempted to reach behind her seat in the direction of Nelson and Nelson slapped the victim on the hand twice, according to the affidavit. According to the arrest affidavit, Nelson told the bus driver, Bradley Mckean, to take the victim home first, changing the regular bus route. Nelson was seen sitting next to the victim for the remainder of the bus ride and it appeared as if she was attempting to push the victim down into the seat to further limit her mobility. Deputies interviewed Nelson the following day. Nelson told deputies she did not remember hitting the victim on the head. She told deputies she was trying to get another child off the school bus and the victim kept on beating on the window and trying to get up out of her seat. Deputies did not observe the victim beating on the window of the school bus or acting in a disruptive manner as described by Nelson. Brenda stated, "I guess I done it. I didn't remember hitting her." Brenda also stated, "I must have just lost it. I don't remember doing that. I would never hit one of those kids."Brenda Nelson was arrested and transported to Polk County Jail.Due to the Veterans Day holiday, the Sheriff's Office does not have access to the video mentioned in the affidavit. The Polk County School Board released the following statement:  3005

LA JOLLA, Calif. (KGTV) - Scientists at Stemson Therapeutics say they've found a way to create new hair cells that could become a cure for baldness."We're hoping this will be the breakthrough," says Chief Scientific Officer Alexey Terskikh.For a few years, they've been working on a two-part process that turns stem cells into hair follicles. It then implants the follicle cells into the scalp to grow new hair."We have the capability to generate brand new hair follicles," says Stemson CEO Geoff Hamilton.Using iPSC's, stem cells derived from a person's blood or existing cells, Terskikh's team can direct them to become folliculogenic cells, the building blocks of hair.They then put the cells into a microscopic scaffold-like mold made on a 3D printer. The molds are about 1/5 the size of a single strand of hair.RELATED: Here are some options if you start going baldThe scaffolds help keep the cells intact, while also telling the hair which direction to grow. That will help avoid in-grown hair or hair that grows in unnatural ways."Imagine transplanting thousands, or tens of thousands of those into a scalp," says Hamilton.Their technique is different from current hair restoration therapy because it grows new hair cells. Existing methods like Rogaine or Propecia try to revive dead cells or transplant existing cells from one area of the body to another."We're inventing as we go," says Hamilton. "We're making up the path ahead of us as we go."Eventually, they say the cost of the new cells will be similar to the cost of hair transplant surgery now, which can run upwards of ,000.In addition to being a cosmetic solution for people who have gone bald naturally, Hamilton says this could help people who have lost hair due to chemotherapy treatment or from severe burns or injuries.So far, testing has proven successful in mice. Human testing is still years away as the company works towards FDA approval.Stemson's lab is part of the Sanford Burnham Prebys Medical Discovery Institute. 2007

Last year's seasonal flu vaccine effectiveness was just 42%, the US Centers for Disease Control and Prevention estimated. Even if vaccinated, then, people had inadequate protection against the flu.This limited effectiveness was due to a mutation that occurred in the influenza A (H3N2) vaccine strain, according to a new study published Monday in the journal Proceedings of the National Academy of Sciences. This vaccine mutation resulted from an egg-based manufacturing process commonly used today.This year's flu vaccine may also be imperfect, said Scott Hensley, author of the new study and an associate professor at the University of Pennsylvania. Add to that, he said, "this could end up being a pretty bad flu season."Still, he said, "our best protection" against severe illness is getting vaccinated with the flu shot we have today.Finding answersEach year before flu season begins, a vaccine is made based on whichever virus strains are expected to circulate. The selected seed strains are distributed to vaccine manufacturers which then produce their formulations and make them available to health care professionals before the season begins.During the 2015-16 season, vaccine effectiveness was 47%, while for the previous 2014-15 season, effectiveness was just 19%, according to the CDC. While the overall effectiveness of last season's vaccine was 42%, it was only 34% effective against the H3N2 viruses that dominated the season.Vaccine effectiveness varies based on how well it matches the circulating virus strains. Sometimes, a vaccine corresponds to the predominant virus yet its effectiveness is still not what scientists would expect. Trying to understand which element of the vaccine failed is difficult.Hensley and his team began their investigation of last year's vaccine by looking at the seed strains that had been distributed to vaccine manufacturers. These seed strains had been propagated in chicken eggs, the common method used today."The sequences of these viruses are available and when we did an alignment to see what the sequence of these vaccines were compared to the viruses that were circulating, it became very obvious that there was this mutation," said Hensley.To see the effects of the mutation, the team next looked at how the immune systems of both animals and humans who'd been inoculated with an egg-based flu vaccine responded to the actual circulating viruses.The antibodies -- immune system proteins that fight invading pathogens -- elicited in both animals and humans failed to bind to and neutralize the flu viruses, Hensley and his colleagues found.While most vaccines in the United States are made in chicken eggs, a small fraction are produced in insects or mammalian cells, Hensley explained. (These are given to people with egg allergies.) He and his team compared immune responses in animals and humans who had received a cell-based vaccine -- in this case, Flublok made by Protein Sciences Corporation."And we found both animals and humans receiving that (cell-based) vaccine had superior antibody responses that could bind and neutralize these circulating H3N2 strains," said Hensley.Making a better vaccine"Most of the infrastructure to produce vaccines in the US is based on chicken eggs," said Hensley. There are good reasons for this, including the fact that egg-based propagation allows manufacturers to quickly produce large quantities of vaccine.While egg adaptations have always been a problem, beginning last year it had become a "huge problem," said Hensley. "As soon as you try to grow this virus in eggs, within a few hours, the virus will acquire this kind of mutation."This is not an easy problem to fix, he said. To produce vaccines in cells means "a very expensive process for companies to just change their overall manufacturing process," Hensley explained. "You can't really do that on the drop of a dime."Meanwhile, the same seed strains used last year are being used this year to make the current vaccine, said Hensley."This year may be especially difficult because, in addition to this egg adaptive mutation which was present last year, there's indication that the H3N2 viruses are actually evolving," said Hensley.Not only will the vaccine be a mismatch with the actual circulating viruses due to egg adaptation but the vaccine could also be a mismatch due to unexpected viral evolution.What kind of flu season is ahead?It's too early to speculate which viruses will become dominant in the United States over the course of the coming flu season, said Hensley, "but it's starting to look like it will be H3 viruses." H3 viruses are influenza A viruses."There are the A group of viruses and the B groups," said Dr. William Schaffner, an infectious disease specialist at Vanderbilt University. "The A groups are the ones that usually are responsible for large epidemics ... whereas the B flu strains usually smolder along. They always cause illness -- it can be just as severe as the A strains -- but they don't produce large outbreaks."Though last year's vaccine was mostly ineffective in thwarting the flu, it still prevented nearly 30% of hospitalizations that might have resulted, according to CDC calculations. For older adults, that rate was even higher, at 37%. Plus, the vaccine reduced outpatient visits by 42% last season.The CDC advises everyone 6 months and older to get a flu shot, as only injectable flu vaccines are recommended. More than 130 million doses of flu vaccine have been distributed so far this year and flu activity is still low across the nation.It's still early days, but experts believe we may be facing a tough season, and not only because of vaccine concerns.The reason?Australia had a tough flu season this year, with a total of 215,280 laboratory-confirmed cases and 504 flu-associated deaths reported to its National Notifiable Diseases Surveillance System as of October 13, government data show. According to a surveillance system report, adults over the age of 80 and children between 5 and 9 years old have been most affected."In general, we get in our season what the Southern Hemisphere got in the season immediately preceding us," Dr. Anthony Fauci, director of the United States' National Institute of Allergy and Infectious Diseases, said in an interview last month.An "intelligent guess," therefore, is that the Northern Hemisphere, like the Southern Hemisphere, will likely battle more cases of the viral infection, he said, though "with influenza, it is never 100%.""If H3N2 viruses dominate the US flu season again this year, vaccine effectiveness will likely be moderate to low again," said Hensley.Still, he said, everyone should get their annual flu shot."The other components of the vaccine, like H1N1 and influenza B, will likely provide excellent protection," said Hensley. "The vaccine will also likely prevent severe disease and death caused by H3N2 viruses, even though this component of the vaccine is mismatched."  6969

LA MESA, Calif. (KGTV) -- Local cannabis shops are sounding the alarm, saying higher state tax rates set to take effect next year will drive more customers to the black market.Starting January 1, the state will change the way it calculates the excise tax on all marijuana products, effectively raising the rate by 12.5 percent. The state will also adjust a fee charged to growers by the rate of inflation, raising it to .65 per ounce of flower from .25 per ounce.Marijuana is also subject to sales tax and local taxes, which at the Reserve dispensary in La Mesa is an extra 8.5 percent and 4 percent respectively.RELATED: Exclusive: Police raid illegal Chula Vista pot shop, as prosecution efforts ramp up“What we have here is a clean, safe product, but those extra taxes push people away because they don’t want to spend the extra money,” said Reserve budtender Owen Horsman. “And when that happens, they go and find their product at an unlicensed or illegal spot.”Industry analysts estimate the illegal market still overshadows California’s legal industry, capturing dollars for every spent at a licensed shop.Reserve owner Gregg Holda said the higher taxes will only widen the price gap between the two markets, and further incentivize customers to buy unlicensed cannabis products, which may be counterfeit or untested.“Unfortunately you could be consuming pesticides, molds, stuff that’s really bad,” he said.RELATED: 6 arrested at Chula Vista pot dispensaryIn a statement, the California Department of Tax and Fee Administration said the changes were required by the language of Proposition 64. The agency said it analyzed thousands of transactions and determined the state excise tax wasn’t capturing 15 percent of gross receipts of all cannabis sales, as the law requires. The CDTFA is required to analyze cannabis transactions and set the tax rate every six months. The agency said the changes are designed to capture the appropriate amount of tax revenue that voters approved.The explanation has not reassured marijuana industry leaders.“We believe that the CDTFA’s decision to increase tax burdens on compliant operators is counter to developing a safe industry,” said the California Cannabis Industry in a statement. 2246

La Mesa (KGTV)- It’s being called one of the most progressive marijuana ordinances in the county. The city of La Mesa plans to unveil its proposed rules this week. City leaders believe lifting limits is the key to defeating illegal pot shops. If passed, the City of La Mesa would be the first in the county to put forth an ordinance without a hard cap on the number of dispensaries within city limits. “We didn’t play that game,” says La Mesa City Council Member Bill Baber. “We’re basically saying they’re in our commercial areas, they have to be regulated, and the market itself will flush out how many get to exist.” Councilmember Bill Baber says the proposed ordinance would weed out illegal pot shops by operating a path to run a legitimate business. It’s a different approach than the one in Chula Vista. City leaders hope a limited number of legal dispensaries will drive customers away from illegal pot shops. Currently, there is only one legally operating dispensary within La Mesa city limits. “We’re proposing our dispensaries that have legally been selling medicinal marijuana to also move one step forward and to sell recreational. It’s the same product.”Under the new laws, the dispensaries will be taxed. The money will go to the city’s general fund. It will help with putting more officers on the street and shutting down illegal operations. Councilman Baber says the city estimates the new ordinance will bring in nearly million a year in city taxes. The funds will also be used to clean up old run-down buildings that once housed illegal dispensaries. “In 4 years our city attorney and our police have shut down 26 of these,” says Baber. West La Mesa Resident, Erik Egelko, says the boarded-up businesses are now bringing in squatters. Behind an old, illegal pot shop on El Cajon Boulevard sits old furniture, trash and the rancid smell of urine. “It just really turned into a slum,” says Egelko. “I see west la Mesa as having this incredible potential.” The La Mesa City Council will be reviewing the ordinance during tomorrow’s city council meeting. There will be public comments for residents to weight in. 2139
