SAN DIEGO (KGTV) - Anyone touched by Alzheimer's knows how painful the disease is. "It's affected my family. It's affected most families. It's such a prevalent disease. As people get older, it becomes quite likely this will become an issue," said Paul Aisen, director of USC's Alzheimer's Therapeutic Research Clinic (ACTC).Aisen's team began their research in San Diego many years ago and teamed up with USC about four years ago. He's spent over 30 years trying to solve Alzheimer's mysteries and is leading the upcoming clinical trial.Aisen says the large-scale study is the culmination of decades of work from scientists worldwide."Our focus lately has been trying to alter the disease, prevent it, or significantly slow its progression. How should we do that? We think attacking amyloid early is the most promising approach," said Aisen. Researchers believe sticky amyloid deposits, which form on the brain later in life, start the Alzheimer's process. Aging, genetics, and lifestyle factors can all contribute to amyloid build-up.The worldwide clinical trial aims to target amyloid. A drug called BAN2401 will be delivered intravenously, designed to bind to the sticky amyloid. The binding neutralizes beta amyloid and helps "tag" it, so the immune system can recognize it and clear it from the brain. A previous phase 2 study showed that BAN2401 removes brain amyloid and possibly slows cognitive decline.They're seeking participants over 50 who are not yet showing symptoms of Alzheimer's but do have elevated amounts of amyloid on their brain. Researchers can determine that through a PET scan or spinal tap. "We think that the most promising approach of all is to take a vigorous attack on amyloid while the brain is still functioning normally. And we can see amyloid in people many years before they develop the symptoms of Alzheimer's."Investigators hope that by treating a patient with BAN2401 very early in the disease, before symptoms occur, it will significantly slow disease progression. "If we're successful, it will have a huge impact on human health," said Aisen. There will be 100 sites worldwide for the study, including major cities like San Diego and Los Angeles. Study participants will receive treatment for four years, given either the drug or a placebo. Results are expected in seven years, Aisen says.

SAN DIEGO (KGTV) — As California deals with its worst energy crisis in two decades and the threat of more rolling blackouts, a lot of people are wondering who -- or what -- is to blame.Energy experts say last weekend’s blackouts are raising new questions about the way the state manages its electrical grid. California is the only state in the west that uses an independent system operator, an entity known as Cal ISO.“This is really just a demonstration that the reliability of the grid is less reliable with [Cal ISO] than when we just had regular utilities,” said San Diego-based energy consultant Bill Powers.Cal ISO manages 80 percent of California’s power grid. It manages the flow of electricity for investor-owned utilities like an air traffic controller manages the flow of privately owned airplanes down a runway. City-owned utilities like the Los Angeles Department of Water and Power are not part of the Cal ISO system.Cal ISO, previously known as CAISO, was formed in 1998 after regulatory changes during the Clinton administration that were designed to make the energy market more competitive.Powers said the fundamental idea was simple: “instead of having these monopoly utilities controlling everything, let's open up the transmission systems.”But it didn’t take long for flaws in the system to emerge. In 2001, market manipulation from companies like Enron prompted dozens of rolling blackouts.In other states like Arizona, utilities are responsible for the electrical transmission within their service territory. Those utilities are able to rapidly respond if conditions prompt the need for additional power generation, Powers said.“[It’s] one-stop shopping. Here it’s two-stop shopping,” he said. “You've got another layer of fat in there. And if that layer of fat is playing the game a different way, simply making sure everyone is covered, then you have the potential to have a breakdown. And we're now experiencing a breakdown.”The most recent major breakdown was in 2011, when 1.4 million San Diegans suddenly found themselves in the dark.A federal investigation into the Great Blackout of 2011 cited “inadequate real-time situational awareness” -- basically bad grid management -- and faulted several entities, including Cal ISO.Edward Lopez, the executive director of the Utility Consumers’ Action Network, said last weekend’s rolling blackouts were another example of bad grid management.“This is an indication that, again, this statewide organization needs to be better prepared and ready to jump into action quicker,” he said.Cal ISO blames another state agency for the recent rolling blackouts, the California Public Utilities Commission, along with California’s evolving energy portfolio.About one-third of the energy California now generates in-state is from renewable sources like solar and wind. When clouds roll in and the winds subside, that can be a problem.“Lack of resources, the heat, those go into account,” Lopez said, “but on the other hand, this was not unpredictable.”Even though more Californians have been staying home due to the pandemic, last weekend’s conditions were not particularly remarkable, he said. With the impact of climate change, above normal temperatures are expected to become more common.One solution to California’s renewable energy problem, he said, is to invest in more energy storage.Cal ISO’s own data shows energy demand last weekend was lower than in previous peak years and there were reserves available, Powers said.“Why do we keep reserves if we’re not willing to use those reserves when conditions get tight?” Powers said.City-owned utilities like LADWP that are independent from Cal ISO did not experience rolling blackouts, one reason Powers thinks there’s a problem with California’s energy air traffic controller.“Maybe we need better rules. Maybe we need a different system,” he said. 3871

SAN DIEGO (KGTV) - As the Valley Fire raged across parts of eastern San Diego County, emergency assistance workers put into action plans they'd been working on for months to handle the dual disaster of a wildfire during a pandemic."It completely changed our approach," says Red Cross Regional CEO Sean Mahoney.The Red Cross has been planning and training for months, knowing this situation would likely arise this fall.Mahoney says their plan included Temporary Evacuation Points instead of group shelters, hotel rooms for people who needed somewhere to stay, grab and go or delivery meals, and an emphasis on sanitation and health screenings to keep volunteers and evacuees safe."We planned for this as much as we possibly could, but exercise is just an exercise. Doing the real thing is where you have those real lessons learned," Mahoney says.During the Valley Fire, the Red Cross assisted 440 people in 174 families. They served around 9,000 meals and snacks.Mahoney says his staff's dedication, along with 107 volunteers who worked 12-hour shifts, helped things go smoothly.But not everything went according to plan. On the first night of evacuations, the Red Cross ran out of hotel rooms, especially for people who had pets. Some evacuees without RVs had to sleep in their cars.Mahoney says the busy Labor Day Weekend, combined with hotel capacity restrictions because of the coronavirus, leads to fewer available rooms.To make sure it doesn't happen again, Mahoney says the Red Cross is already working on backup plans to open limited group shelters, with social distancing put in place to keep people apart. He told 10News they've already scouted hundreds of locations around San Diego.Meanwhile, the San Diego Humane Society also put in new protocols for safety during the pandemic. They helped hundreds of animals during the Valley Fire, and say the most significant challenges were limiting contact with owners and making sure their field teams followed the rules about distancing and wearing masks."The more people you interact with, the more likely you are to come in contact with somebody who is transmitting coronavirus," says Lt. John Peaveler. "So, we've had our biggest safety precautions on that side."Both groups say they'll take all the Valley Fire experience and put it to use in the next disaster. Since wildfire season is just beginning, they're sure it will come in handy. 2405

SAN DIEGO (KGTV) -- California is the worst state for military retirees when it comes to the cost of housing, according to WalletHub. Overall, California ranked 21st on the list of best and worst states for military retirees. The Golden State ranked 9th for quality of life, 3rd for number of VA health facilities per number of veterans and 5th for number of VA benefits-administration facilities per number of veterans. Dragging California down to the 21st spot however, is the cost of living. The state ranked 51st for housing affordability and 49th for percent of veteran-owned businesses. California also ranked 48th for its percentage of homeless veterans and 12th for veteran job opportunities. The report also found that red states are friendlier to military retirees than blue states. 802

SAN DIEGO (KGTV) — As people continue to wipe out store shelves and stock up on essential items, a new app called Markk is helping users locate where products like water, eggs, and toilet paper are actually in stock."I think the main thing that makes us happy, is it's helping people out there," said co-founder, Shachin Bharadwaj.What started off as a visual, real-time review app in late August, quickly pivoted to an emergency supply finder amid the coronavirus pandemic.RELATED: San Diego grocery stores hiring to address demand amid virus"You can take photos and videos of the store with items you want to focus on," said Bharadwaj.Markk gives users the ability to take pictures or videos of the in stock essential items, in real-time, then tag their location and post."It's like an Instagram story basically," said Bharadwaj.RELATED: Will you qualify for a ,200 COVID-19 stimulus check?Your location must be enabled while using the app, but it only shows up to other users when posting from a store.The pictures or videos get marked on a map and may stay there for up to 24 hours."If you see new users coming into the same place and giving a better marking, the older marking automatically expires," explained Bharadwaj.RELATED: Grocery stores with hours for seniors amid coronavirus pandemicYou can also let users know what's out of stock, saving your neighbors a trip and reducing crowding in grocery stores."If you can help people in the community report essentials, when you are out buying stuff for yourself, then I think you are helping the greater cause," he said.This is only the third week the emergency supply finder has been in use, it is available worldwide but have mostly been used in Los Angeles.RELATED: 3.3 million seek US jobless aid, nearly 5 times earlier highBharadwak is hoping to get the word out so neighbors can begin helping each other during this unusual time."It will really help the community kind of be stronger and bring something for each other," he said.Markk is available in the Apple App Store as well as the Google Play Store. 2078
