SAN DIEGO (KGTV) — Kensington's historic Ken Cinema, an institution in the San Diego neighborhood for nearly 75 years, is closing its doors for good this March.The theater will shut down after March 22, a spokesperson with owner Landmark Theaters told 10News.According to the spokesperson, "After long consideration and much effort, we regret that we are unable to continue operating the Ken Cinema ... The company recognizes what a cherished asset the Ken has been to the neighboring community. The changing theatrical landscape and challenges to independent exhibition are the major contributing factors."RELATED: Poway bowling alley to close in latest big change to busy corridorSince 1946, Ken Cinemas has operated in Kensington on Adams Avenue, bringing local theater-goers independent and foreign films, and restored classic movies. It was the first theater to specialize in the film genres in San Diego.According to Landmark Theaters, the 300-seat cinema is the last single-screen theater in San Diego.In 1975, Landmark Theaters became the theater's owner. The Ken had already faced closure under the Landmark brand in 2014, leading to outraged fans voicing their concerns on social media. The cinema was able to reach a new lease agreement with Landmark, according to San Diego Magazine.RELATED: Mostra Coffee goes from garage to world championsThe company said it will continue the theater's independent and foreign film programs at Hillcrest Cinemas, which it also owns.It's not clear what will become of the historic property after the cinema shuts down.When asked what will happen to the cinema's current staff, the company didn't immediately provide an answer. 1681

SAN DIEGO (KGTV) — In their push to reopen schools, some political supporters of President Donald Trump have cited COVID-19 research from a group of San Diego scientists, claiming it’s evidence we could be close to herd immunity from the virus.But one of the authors of that research says that conclusion is way off.One of the most prominent supporters of the herd immunity conjecture is Dr. Scott Atlas, a neuroradiologist and senior fellow at Stanford University’s Hoover Institution who became an adviser to President Trump this month.“There’s a pretty good chance that herd immunity requires way less infections because of existing immunity out there,” Atlas said in a livestream conversation with San Diego County Supervisor Jim Desmond. “It actually may have already been reached in places like New York. We don’t know, but it’s possible.”Herd immunity is the level of protection needed to effectively stop the virus from circulating, thought to be about 70 percent of the population. The “existing immunity” to which Atlas is referring has to do with T cells.“It's just a misunderstanding of the science,” said Dr. Shane Crotty, a virologist at the La Jolla Institute for Immunology who co-authored the groundbreaking research on T cells in June.Crotty and his colleagues found that 50 percent of people unexposed to the novel coronavirus had T cells that could recognize it. Scientists refer to this as cross-reactive T cells, and the study was replicated in other countries.Proponents of the herd immunity theory take the number of people infected with the coronavirus, add the number of people with T cells that can recognize the virus, and come up with a number around the herd immunity threshold of 70 percent. But the math doesn’t work that way, according to Crotty, in part because T cells only kick in once a virus has hijacked cells, meaning T cells alone can't stop a pathogen in its tracks.“We’re not saying those 50 percent of people have protection like they’ve already had the virus,” Crotty said. “We’re saying those 50 percent of people have a head start in responding to the virus, which is a good thing but doesn’t affect herd immunity.”Since the novel coronavirus is a new pathogen, scientists did not expect people would have tools in their immune system capable of recognizing it. Unexposed people do not have cross-reactive antibodies, Crotty said.But in a study published this month in Science, Dr. Crotty and his colleagues offered a potential explanation for the surprising T cell results: they found these cross-reactive T cells also recognized four other coronavirus strains that cause common colds.Their theory: the T cells were created in response to other coronaviruses but can recognize SARS-CoV-2 like a distant relative.“It's a memory of a cousin,” Dr. Crotty said.That memory may speed up the body’s immune response, which can normally take about a week for an unknown pathogen, Crotty said. But scientists aren’t sure yet what role T cells actually play in clinical outcomes.“We have no data and and neither does anybody else as to whether these T cells really help or not,” Crotty said.To answer that question, scientists would need blood samples for lots of healthy people and then they would have to closely study individuals who got infected.The La Jolla Institute for Immunology is raising money for that kind of research, Crotty said, but they’re not there yet. 3417

SAN DIEGO (KGTV) — In Pacific Beach, it's common to see scooters in the flow of traffic.At night, it's the same story. Firefighters plagued with trauma patients from scooter crashes. Crews say they often see people using them to bar hop.A study released Thursday reveals data supporting exactly that. The study focuses on 103 patients and after tests it shows that half of them were drunk. Even more surprising, 52% were high on drugs.The study pulled data from UCSD Medical Center, Scripps Mercy Medical Center, and a hospital in Austin, Texas."We were concerned this would become the next big public health issue," says UC San Diego Health Dr. Leslie Kobayashi.The study looked at patients between September 1, 2017 to October 31, 2018."Spinal fractures and spinal chord injuries," Kobayashi says, recalling injuries. "I myself saw one patient who was not able to be salvaged because of a severe overwhelming devastating head injury."Kobayashi seeing the skyrocketing trend from the emergency room.New rules started in June to combat these stats, like limiting the speed of scooters in places like the boardwalk and forcing riders to park scooters in corrals.Firefighters in Pacific Beach say they're seeing less injuries in the last month.Kobayashi hopes it's just the beginning."Reducing the speeds, limiting the times of day it can be used, and whether or not protective gear, most importantly helmets are going to have an impact on injury prevention," Kobayashi added.The conclusion of the study reads, "eScooter-related trauma has significantly increased over time. Alcohol and illicit substance use among these patients was common, and helmet use was extremely rare. Significant injuries including intracranial hemorrhage and fractures requiring operative intervention were present in over half (51%) of patients. Interventions aimed at increasing helmet use and discouraging eScooter operation while intoxicated are necessary to reduce the burden of eScooter-related trauma."10News reached out to Bird and Lime for a response.Lime said they are "piloting a new function in the app - “Don’t drink and ride” - whereby those trying to rent a Lime after 10pm now have to confirm they are not attempting to rider under the influence."Both companies said safety is their priority.Bird sent us this statement, in part, "The rules of the road, apply to everyone — whether behind the wheel, walking, cycling or on a scooter. We go to great lengths to educate and inform riders about the dangers of distracted riding, including riding under the influence, as well as educating them on how to identify drivers who might be operating cars under the influence." They provide in-app messages and emails reminding riders not to drink and ride.The study acknowledges their information may be skewed, "Using patients only from Level 1 trauma centers may skew our data by excluding many of the less severely injured patients who were triaged to lower level trauma centers and non-trauma centers." 2995

SAN DIEGO (KGTV) — It has now been seven months since the pandemic began, and there are still a lot of questions about the best ways to treat patients with COVID-19.Researchers at UC San Diego are leading an effort to produce swift and reliable answers that could help doctors tailor treatments and hospitals plan bed space more efficiently.Doctors agree: the best way to fight any disease is to tailor the treatment for each individual based on their age, gender, race and other factors. But how does one doctor do that with a new disease like COVID-19, especially if their hospital has only seen a few hundred cases?“There might be some patterns you can get from 500 patients but there might be some others that you cannot,” said UCSD professor Dr. Lucila Ohno-Machado, chair of the Department of Biomedical Informatics.Dr. Ohno-Machado’s solution? Pool data.She’s leading the charge behind COVID19questions.org, a collaboration between 12 medical systems spanning more than 200 hospitals across the country.The collaboration includes several University of California health systems, the University of Texas Health Science Center at Houston, the University of Colorado Anschutz Medical Campus, and the largest organization in the cohort, the Veterans Affairs Healthcare System.“Each hospital is a little small to answer the questions. So by having it all together, we get the answers quicker,” said Ohno-Machado.They’re going after answers on how long patients with diabetes or cancer stay in the hospital, and whether COVID-19 is deadlier for smokers or non-smokers.Their findings revealed that men are much more likely to wind up on a ventilator than women.And they quantified just how much better we’ve gotten at treating COVID-19 over time.Since May 1, hospital stays among surviving patients have shrunk more than 10 days on average. That’s important for hospital managers planning and predicting bed space.“We decided to open this to the public and to our colleagues, and then we pick which answers have not been answered before and seem to be of most general interest,” Dr. Ohno-Machado explained.If this sounds like a straightforward approach, it’s not. Patient confidentiality laws make it hard for hospitals to share data and the information released by the CDC is limited.Maintaining patient confidentiality while sharing granular data is the most groundbreaking feature of the collaboration, called Reliable Response Data Discovery or known by its Star Wars-inspired acronym, R2D2.UCSD said R2D2 differs from other patient databases and registries because each health system maintains control of data rather than sharing it in a central repository. Through advanced computer techniques, each partner agency shares aggregated data, not patient-level information.The collaboration’s research is based on what’s called “observational data,” so Dr. Ohno-Machado said it’s not a replacement for a randomized, controlled clinical trial, which takes time. She noted their data reflects lessons on hospitalized patients, not everyone infected with the virus.But she said at a time when fast answers can save lives, COVID19questions.org could help. 3161

SAN DIEGO (KGTV) – It's exploding in the wellness industry, but is CBD safe? 10News visited a San Diego lab that tested CBD products for ingredients like pesticides and heavy metals. The results were surprising to lab personnel. Shelby Huffaker is the lead cannabis educator at Torrey Holistics in Sorrento Valley. The licensed dispensary recently conducted its own CBD study to show customers just how unreliable the open market can be. "We collected about a dozen different products from various locations around San Diego and also on the internet," she tells 10News. Torrey Holistics collected samples from places like farmers' markets, grocery stores, and the internet. The company bought CBD products such as lip balms, caramels, creams, and bath bombs, then sent to San Diego's Infinite Chemical Analysis Labs. "It's pretty busy right now with it being harvest time," says David Marelius, Ph.D. He's the co-founder of Infinite Chemical Analysis Labs, which tests cannabis and related products. "People are definitely trying to take advantage of the CBD boom right now," he adds. Both CBD and THC come from the cannabis plant, but CBD does not have the psychoactive properties that give you the feeling of being high. CBD received praised for claims of health benefits like reducing anxiety and inflammation. According to Infinite Chemical Analysis Labs, none of the CBD samples purchased on the internet by Torrey Holistics had any CBD in them. Dr. Marelius tells 10News that the majority of the overall samples didn't meet their packaging claims. He adds that the products' potencies were off, and one product had almost 70% less CBD in it than what it advertised. Three of the products reportedly failed for pesticides, although the levels were so low that they likely weren't harmful. "It's kind of the wild west out there," says Sally Greenberg with the National Consumers League. Greenberg tells 10News that CBD sellers often exaggerate the benefits of CBD without having the science to back up the claims. "[They say] that they cure cancer or treat Alzheimer's or treat AIDS," she adds. The National Consumers League is advocating for federal oversight from the Food and Drug Administration, which currently doesn't regulate most CBD. In California, the Bureau of Cannabis Control tests CBD that's sold in licensed dispensaries, like Torrey Holistics. "You're going to want to look for a Batch number or UID number. That ensures that we're able to match the testing results with that specific product," says Huffaker. The dispensary is hoping that the lab results will highlight the importance of researching your CBD before buying. "Everything carried in a licensed cannabis store is going to have to be verified [and] vetted by the dispensary [to be sure] it has gone through the necessary testing," adds Huffaker. The state's Bureau of Cannabis Control has a search function on its website where you can see what licensed dispensaries are in your area, or you can search a dispensary to be sure its licensed.
