SAN DIEGO (KGTV) — There are still many unknowns surrounding SARS-CoV-2, the official name of the new coronavirus, but almost from the beginning one thing has been clear: people with underlying health conditions are more at-risk.San Diego County Health officials released new data this month showing which underlying conditions pose the greatest risk of death from COVID-19, based on the number of times a condition was listed on death certificates and other medical records.Among the 626 COVID deaths recorded in San Diego County as of Tuesday, 96 percent of the victims had at least one underlying condition. Only 4 percent, or 27 people, died without evidence of an underlying condition.Hypertension (high blood pressure) -- listed in 50% of deathsDiabetes -- 35%Cardiac Disease -- 31%Dementia/Alzheimer’s -- 27%Chronic Kidney Disease -- 18%COPD/Asthma -- 13%Obesity -- 8%Immunocompromised -- 5%No underlying condition -- 4%So what makes these conditions more risky than others? It may have to do with the prevalence of these conditions in the population and the way SARS-CoV-2 attacks the body, according to Sharp Rees-Stealy physician Dr. Abisola Olulade.Scientists are still scrambling to understand exactly how SARS-CoV-2 attacks and kills patients, but emerging research offers some theories.It starts when virus particles enter a person’s nose or mouth. The coronavirus makes it way towards the lungs first, and the immune system tries to fight it, causing inflammation along the way that can lead to pneumonia.People with hypertension and diabetes, the top two underlying conditions in San Diego County’s data, often have existing damage to their blood vessels.Based on early studies, scientists theorize the virus may be causing more damage to the vessel through inflammation and clotting, or outright attacking the blood vessels themselves.On top of that, hypertension is common: “Almost half of all adults in the United States have hypertension,” Dr. Olulade said. “45 percent.”Patients with cardiac disease, like coronary heart disease and congestive heart failure, have existing damage to their heart.Early research shows the coronavirus can cause inflammation of the heart muscle. It might also damage the heart indirectly, as the fight with the immune system in the lungs lowers oxygen levels in the blood.“If your heart isn’t pumping enough oxygen out to the blood, that amplifies the risk and the threat of dying from COVID,” Dr. Olulade said.Patients with dementia, the fourth most common condition on the list, already have an elevated risk of dying from pneumonia, one of the calling cards of a severe COVID-19 infection. People with diabetes also have a risk of pneumonia. In fact, the risk is so high, the CDC recommends patients with diabetes get a pneumonia vaccination.For individuals with chronic kidney disease, scientists aren’t yet sure if the virus attacks the kidneys directly or the kidneys get hit with collateral damage from other body system failures.Regardless of the underlying condition, Dr. Olulade said taking steps to treat and keep it under control can greatly reduce your risk from the coronavirus.Individuals with mild or controlled asthma, for example, are not considered to be at higher risk of severe illness, she said.San Diego County’s list does not include two underlying conditions considered high risk by the Centers for Disease Control and Prevention: cancer and sickle cell disease.That might be because the 626 deaths are a small sample size, Dr. Olulade said. 3525

SAN DIEGO (KGTV) - There is a memorial of candles, notes, and flowers along 4th Avenue near Main Street in Chula Vista.They are in memory of 23-year-old Christina Garcia, who was found dead at a nearby field on Aug. 5th. Chula Vista police say they were called out to 3100 block of Main Street after someone found her body. They say she had an apparent gunshot wound and opened a homicide case.“That afternoon, she wanted to see her daughter and pick up the truck, so it was a brief encounter,” her mother, Lisa Garcia, said. “I expected her to come back, and I wish I took advantage of that situation longer.”Lisa says Christina leaves behind a two-year-old daughter.“I think the saddest thing for me is that her daughter is only going to know her through pictures because she’s so young,” She said. “She’s never going to remember her mom’s touch, her kiss, her voice.”Lisa says her daughter was very likable and smart.“She tested out in the 10th grade and started southwestern college and finished her classes there,” Lisa said. She was also a skilled welder and liked working with her hands. Most recently, they bought a home and worked on remodeling it.“She’s very hands-on, like her mom,” Lisa said, “you know, taking the popcorn ceiling down, remodeling the walls.”She says it’s been tough knowing Christina’s killer has not been caught. Lisa says she has many questions and is cannot find any closure without finding answers.“Was she dumped there? Was she shot there? So my brain is at 100 miles per hour trying to come up with all these scenarios,” she said.Police are asking for witnesses or anyone with information to come forward, saying they can even remain anonymous through Crime Stoppers.“There might be information out there that people think is irrelevant,” Lisa said. “But it could be very relevant to law enforcement.” 1845

SAN DIEGO (KGTV) - The San Diego Fertility Center will be the first in the nation to deploy new robotic technology that will help store, track and maintain frozen embryos for In-Vitro Fertilization.The TMRW Robot will be in use by next month at the center in Carmel Valley. It will take 17,000 measurements every day to make sure the embryos are kept in prime conditions.It also codes each embryo and egg with a specific Radio Frequency ID to make sure scientists can track each one."There needs to be this level of trust between the mother and father and the caretakers of their embryos," says Dr. Michael Kettel with the SDFC. "I think this goes one step further in building that trust."Since IVF treatment began, most of the storage and measurements taken on embryos has been done by hand, in tanks that hold up to 1,000 samples. The TMRW Robot will have room for nearly 20,000 embryos and make the process fully automatic. Doctors say that will remove any possibility of human error."We can't make a mistake," says SDFC Laboratory Director Bill Venier. "This machine will not let us make a mistake."IVF mistakes have been in the news recently as families have filed lawsuits over embryos being given to the wrong parents. Venier says the TMRW Robot will all but eliminate the chance of that happening."We'll have 24/7, 365 (monitoring of) 17,000 data points to let us know everything is safe and is not going to be affected whatsoever," he says. RELATED: Mother gives birth to other couples' babies because of IVF mix upThe technological leap forward was necessary as IVF pregnancies become more common. The CDC says 21 million people will use some kind of IVF method or storage by 2025. It also estimates that there will be 200-300 million babies born through IVF by the year 2100. RELATED: IVF births expected to skyrocket this century"I am certain you cannot go to a kindergarten class in San Diego where one of those children wasn't born through an IVF or some sort of fertility procedure," says Dr. Kettel.For the San Diego Fertility Center, the new robot means they'll be at the forefront of the future of the industry. 2138

SAN DIEGO (KGTV) - These days, it's hard to go a block in the East Village without seeing a restaurant that's out of business.Recently, the Tilted Kilt, Market Hall, Smashburger, and Sol Cal Cafe have all shuttered. "I just noticed constant, consistent places are closing around here," said Ed Korb, who was visiting the area Thursday.Alina Ahmed, who owns Cafe De L'Opera, on J Street, says it's ever-increasing rents, and higher costs like minimum wage and electricity that are squeezing her, and causing her colleagues to close. She's been in business for five years, and says it gets harder each time the calendar turns. "Everybody thinks that because you're close to Petco Park, which is a great location, you're going to make a lot of money," she said. Ahmed says she tried keeping her cafe open during Padre games, but even then the foot traffic couldn't justify it.The East Village Association, which keeps a directory businesses, said in a statement that this part of the evolution of the neighborhood."As the East Village community continues to grow, so to does the sophistication of our businesses housing and residents, which lends to a competitive higher end urban environment, offering a uniquely downtown San Diego experience," the association said. A spokeswoman for the Tilted Kilt, which also closed its Mission Valley location earlier this year, said the owner of the space near Petco Park wanted to go in a different direction.   1502
