SAN DIEGO (KGTV) — Tourists and locals alike can enjoy one of San Diego's most famous landmarks Saturday for free in honor of National Public Lands Day.The National Park Service is offering free entry at Cabrillo National Monument, and other U.S. landmarks, as part of its "fee-free" days throughout the year. The last free admission day of the year is Nov. 11 in honor of Veterans Day.Not only that, but Saturday also marks the day when Cabrillo first sailed into San Diego Bay in 1542.RELATED: Six great San Diego spots where you can unwindOn Saturday, guests can also learn about how 16th century explorers navigated with such accurate results, or go inside the Fort Rosecrans bunkers at the site that date back to World War II. As part of the day, a volunteer event to clean up trails is also scheduled.Visitors will without a doubt enjoy the trek to the tip of Point Loma, where a monument to the Spanish explorer sits to mark his landing at the site. Living history re-enactors will be in attendance to walk guests through the Age of Exploration.Films are also shown daily at the monument covering Cabrillo, the lighthouse, and nearby aquatic life. And it's always a treat to walk inside the Old Point Loma Lighthouse, check out native plants, or trek down a trail to tide pools along the coast.RELATED: San Diego County park rangers recommend these trails in 2019And, of course, there's a magnificent view of the San Diego skyline to behold.National Parks Day was established in 1994 and is always held on the fourth Saturday in September. The holiday marks the largest single-day volunteer effort, as landmarks invite locals out to help maintain the site and enjoy its history during various events. 1715

SAN DIEGO (KGTV) — With hospital beds running short, healthcare workers are trying to care for COVID-19 patients as efficiently as possible, using everything they’ve learned over the last nine months.Improvements in medications and methods have helped shorten hospital stays, said Sharp Memorial Hospital chief medical officer Dr. Tom Lawrie.In March, Sharp said COVID-19 patients stayed 12 days in the hospital on average. In November, the average dropped to 5.3 days. Other institutions have reported similar drops in the length of patient stays.COVID-19 patients now receive a three drug regimen: Remdesivir to fight the virus, a powerful steroid called dexamethasone to prevent the immune system from going haywire, and medications like heparin to reduce blood clotting.On top of that, hospitals have improved techniques like when to use ventilators.“Initially, we were in this conundrum where we weren't sure whether we should intubate patients early or whether we should wait a little later,” Dr. Lawrie said. “Over the last several months we've figured out a really good progression.”The progression now starts with a surprisingly simple technique called proning. Doctors around the country discovered that turning COVID-19 patients onto their stomachs rapidly improved breathing.Early research suggests proning may keep COVID patients off ventilators.“By putting people on their stomach in these positions and by proning them, you allow blood to get where the air is and therefore you get better oxygenation,” Dr. Lawrie said. “It makes the oxygen levels better. It makes their work of breathing better. It makes them feel better generally.”Proning helps move blood from one area of the lung to another where it can receive more oxygen. These regions are called West’s zones of the lung, named after research in the 1960’s by UC San Diego Professor Emeritus John B. West.Proning has been used as a medical intervention since 1976, when a doctor and a nurse in central Michigan published a study showing it could benefit patients in respiratory distress.Dr. Lawrie said there are also two outside factors contributing to shorter hospital stays across the country. The patients that are showing up now tend to be younger than early in the pandemic. Younger patients are more likely to respond well to treatment.There’s also evidence the virus has mutated over time, possibly making it more contagious but slightly less severe, Dr. Lawrie said.However, patients lately have been showing up faster than hospitals can care for them, threatening to overwhelm already crowded facilities. "If that happens, they won't have access to an ICU bed or to the medications that they need," he said. 2699

SAN DIEGO (KGTV) — With another round of coronavirus closures set to begin Saturday, several San Diego County businesses are fighting back legally.Despite the change to California's most restrictive reopening tier, Pacers and Cheetah's adult entertainment clubs won't be shutting their doors. Last week, the businesses won a suit against the county and a judge granted a temporary restraining order allowing them to stay open.An attorney representing Pacers told ABC 10News their argument centered around first amendment rights, and adult entertainment is a protected form of expression. It's unclear if that argument could apply to other businesses, but he added that there are other legal paths to challenging the closures.Another suit has also been filed by a group of San Diego County gyms, but no decision has been made yet.San Diego County Supervisor Kristin Gaspar says the legal actions are understandable given the tough situation."Now we're threatening the workforce again we're threatening the closure of these businesses again and I think this is entirely unsustainable for our business community," Gaspar said. Gaspar added that the county has appealed to the state to avoid the tier change, asking them to take into account other factors, including where a majority of outbreaks are linked to and the county's hospitalization rate."At this point in time our hospitalizations for COVID-19 are at 6%, there's a lot of capacity left in our hospitals system," Gaspar said.On the heels of the successful adult entertainment lawsuit, Gaspar says it stands to reason other businesses could do the same."You could make the case as a restaurant owner as a gym owner that our data does not support this decision to close down and closing down will create undue financial harm to these businesses it has already I think they have a strong compelling case," she said.Although individual businesses are fighting back legally, Gaspar says at this point, it doesn't appear the county has plans to file suit against the state."So far there hasn't been anything that's come out of those closed sessions to suggest that the County of San Diego will proceed along that route," said Gaspar. 2192

SAN DIEGO (KGTV) - What looks like a fire zone on a busy Ocean Beach street is a fraud, the City of San Diego confirmed to 10News Wednesday. The red curb at Abbott Street and Santa Monica Avenue got the attention of neighbors. Diana Webster has lived in the community for 66 years and said people have been getting active with spray paint. “On Friday, five scooters were parked in there and on Saturday, somebody had painted black where all the scooters should be parked. Sounds like there is some suspicious activity with spray cans, I guess so,” Webster said. “I think it’s pretty crazy someone got away with it,” said a neighbor identified as Rodrigo. The city said illegal red curbing happens regularly in parking-dense areas and the best way to take care of it is to report it through their Get It Done app. If the paint looks different than a typical red curb, it’s likely illegal, the city said. 910

SAN DIEGO (KGTV) -- We’ve known for a while that COVID-19 hits people over 65 especially hard, but a study published Wednesday from researchers in San Diego offers new insight into why that happens.The numbers are staggering: if you’re 65 or older, your risk of winding up in the hospital from COVID-19 is five to 11 times higher than someone under 30. Your risk of death is at least 90 times higher, according to data from the Centers for Disease Control and Prevention.Researchers at the La Jolla Institute for Immunology say the reason why older people fare so much worse appears to be from a lack of T-cells, a type of white blood cell that can decline with age.“Some viruses get controlled by one part of the immune system. Some viruses get controlled by another. In this case it seems that T-cells really do a lot of the work,” said Dr. Shane Crotty, one of the authors of the study published Wednesday in the journal Cell.Dr. Crotty and his colleagues looked at 50 people infected with the virus, and they measured the three elements of the adaptive immune system in detail: antibodies, helper T-cells and killer T-cells.Then they compared the measurements to how people fared against the virus. Some patients in the study group had severe cases, others had mild infections.The researchers found that people with all three branches of the adaptive immune system tended to fully recover. People with severe cases of the virus often lacked one or more of the immune branches, and it was particularly evident in older people.“Our data indicated that of the older individuals, it was particularly the ones that had fewer T-cells to start that look like they really struggled to control this virus,” Dr. Crotty said.As we age, we have fewer T-cells to send after invading pathogens. “That collection of T-cells gets smaller. So it’s harder to recognize a new virus,” Crotty said.Among the 748 deaths in San Diego County reported as of Wednesday, 87% were people aged 60 and older.The findings from LJI may have implications in the search for a vaccine against COVID-19. The data suggests that vaccine-makers may want to target a drug that elicits all three branches of the immune response, Dr. Crotty said. Some vaccine approaches, such as inactivated virus vaccines, only elicit two of three branches, not killer T-cells. However, Crotty said it was too soon to rule any candidates. Two strong branches produced by a vaccine could potentially cover for the lack of a third, he said.Crotty said the findings could help vaccine-makers interpret results from the clinical trials and find the right dosing.“Is a given vaccine a good vaccine, and you just need a booster immunization?” he said. “Does it work well in one population but it doesn’t help in the elderly because it doesn’t generate a T-cell response, for example? Those are the scenarios when this type of knowledge will come into play.” 2906
