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) - A San Diego mother and daughter who both have Type 1 Diabetes are navigating the disease together.Keary and Zola Chaney are among the first to use a new device which sends life-saving alerts to your smartwatch or cell phone.The Dexcom G6 is a small sensor that monitors blood sugar levels 24 hours a day and requires no finger-pricking. The FDA-approved sensor is easy to put on and can be worn for 10 days. "I feel like I have more control and diabetes has less control over me, which is the most freeing feeling in the world," said Keary, Zola's mom. Keary says Dexcom, a San Diego-based company, is not only simplifying their lives but also saving them, especially when their blood sugar levels get low. Keary can monitor both her and Zola's blood glucose levels on her smartphone, even if they're thousands of miles apart. The device will be readily available to consumers in June and is covered by most insurance companies.   1007

SAN DIEGO (KGTV) -- Boy Scouts and Girls Scouts from all over San Diego County honored our local veterans laid to rest at Greenwood Memorial Park on Saturday. They placed American flags at the gravesite of every fallen veteran at the cemetery. The event is done all over the country to teach the scouts about patriotism and community service. Also, teaching them about those who made the ultimate sacrifice.RELATED: Memorial Day services around San Diego this yearSince not all of the people laid to rest at Greenwood are veterans, the kids had to look at each gravesite before putting down their flags. The veterans remembered today were from different wars including WWII, the Korean War, and the Vietnam War.10News reporter Laura Acevedo was live on Facebook with the scouts as they placed flags on graves: 837

SAN DIEGO (KGTV) — UC San Diego researchers are testing a technology that's been in development for more than a decade to fight the coronavirus.In lab experiments, "nanosponges" covered in human lung cell membranes and immune cell membranes were found to attract and neutralize the SARS-CoV-2 virus in cell culture, according to a UCSD release. This caused the virus to lose about 90% of infectivity, or its ability to hijack cells and reproduce.The tiny sponges are designed to impersonate and protect healthy cells by soaking up harmful pathogens and toxins, according to Liangfang Zhang, a nanoengineering professor at the UC San Diego Jacobs School of Engineering. RELATED: San Diego company's COVID-19 test gets emergency approvalFor example, the nanoparticle covered in membranes from cell types the virus is known to invade latch on to the virus. This prevent the virus from then entering an actual human cell."Traditionally, drug developers for infectious diseases dive deep on the details of the pathogen in order to find druggable targets. Our approach is different. We only need to know what the target cells are. And then we aim to protect the targets by creating biomimetic decoys," said Zhang.While Zhang has spent the last 10 years developing the technology, his lab turned to using the nano-particle to fight the coronavirus when the pandemic hit.RELATED: Scripps Research's antibodies study shows signs of success against coronavirusNow, the first data on the technology's ability to battle the virus is being released after testing by researchers at Boston University."Another interesting aspect of our approach is that even as SARS-CoV-2 mutates, as long as the virus can still invade the cells we are mimicking, our nanosponge approach should still work. I’m not sure this can be said for some of the vaccines and therapeutics that are currently being developed," said Zhang.UCSD researchers will test the nanosponges’ effectiveness in animal models in the next few months and are moving as fast as possible to eventually test the technology in humans. RELATED: Startup creates mobile COVID-19 testing clinic on wheelsNanosponges have a massive amount of testing ahead before they make it to human tests, Zhang said."I see potential for a preventive treatment, for a therapeutic that could be given early because once the nanosponges get in the lung, they can stay in the lung for some time," Zhang said. "If a virus comes, it could be blocked if there are nanosponges waiting for it."(Read more about the study and nanosponges here.) 2562
