Roughly 40 million people are estimated to wear a fitness tracker of some kind. Now one of those brands, Fitbit, has teamed up with researchers to try and predict COVID-19 symptoms before they start."About seven years ago when these Fitbits and things were coming out as fitness trackers, we said, Well they're probably pretty good physiological markers, not just fitness markers," said Dr. Michael Snyder with Stanford University's School of Medicine.Dr. Snyder says they were first able to use the technology to help them catch early signs of Lyme disease. The current pandemic has prompted them to take their research a step further."They're mostly built around heart rate which we think is better than skin temperature because not everyone gets a fever with COVID," said Dr. Snyder.Stanford's study is taking place in two phases. In the first, researchers evaluated six months of data in a majority of patients who tested positive for COVID-19. Their research showed COVID-19 patients had an elevated resting heart rate up to nine days before showing any symptoms of the virus."I view these as health monitors in the current pandemic. If we start flagging people as early as possible we’re going to be way [ahead in reducing] the number of cases, probably help people in saying no you shouldn’t go to work today. So, it has broad implications for the economy, pandemic spread and personal health period," said Dr. Snyder.Senior Vice President and General Manager of Fitbit Health Solutions, Amy McDonough, agrees."In particular, resting heart rate, heart rate variability, breathing rate all might change as your body is fighting off illness. So the study is really to look at what are the expressed changes that might happen," said McDonough."I think your immune system engages pretty quickly when you get ill and the cells are probably consuming a lot of energy and your heart needs to pound away to create some of them," said Dr. Snyder.Stanford's second phase of the study starts soon. People who have a fitness tracker can sign up and anonymously share their fitness data. Then, they can get alerted when researchers detect an elevated resting heart rate and possible early signs of contracting a virus."To be able to do that earlier detection can help keep people safe and help understand their body and when they might be fighting off illness," said McDonough.Dr. Snyder is confident in the technology, which he says helped him detect his own case of Lyme disease. "In one case which was on me, it was pretty clear I was ill because of the bio marker but I didn’t feel symptoms and my watch even picked that up. So what that tells you is it can detect disease when you’re presymptomatic as well as in asymptomatic cases which is pretty powerful," said Dr. Snyder.People can sign up for Stanford's study by logging into their Fitbit app or heading to innovations.stanford.edu.As for what Dr. Snyder hopes to take away from this study, he said "I hope to plant a wearable device on every person on the planet. Sixty percent of people have a smartphone so it's totally scalable. These are not expensive devices. They could be a lot cheaper than they are and obviously the ones in the future will be much more health-oriented."Eventually they hope to be able to detect the severity of an illness, as well. 3320

SACRAMENTO, Calif. (AP) — California lawmakers are preparing to return to work after an extended summer recess because of the coronavirus. Lawmakers return to Sacramento on Monday and have about five weeks to pass bills. Assembly Speaker Anthony Rendon said many lawmakers want Gov. Gavin Newsom to call them back for a special session to give them more time to pass tough bills. Lawmakers are considering proposals that would prevent landlords from evicting tenants unable to pay their rent during the pandemic and making COVID-19 infections eligible for workers' compensation claims. They are also weighing bills about police brutality and health care. 662

SACRAMENTO, Calif. (AP) — A California appeals court says it's legal to have small amounts of marijuana in prison — so long as inmates don't inhale.The 3rd District Court of Appeal ruled that California voters legalized recreational possession of less than an ounce (28 grams) of cannabis in 2016, with no exception even for those behind bars.But the court says state law does prohibit smoking weed in prison. Prison officials can also still punish pot possession as a rules violation."According to the plain language of ... Proposition 64, possession of less than an ounce of cannabis in prison is no longer a felony," the court ruled Tuesday. "Smoking or ingesting cannabis in prison remains a felony."RELATED: City votes in favor of marijuana production site in Kearny MesaThe court overturned the Sacramento County convictions of five inmates who had been found with marijuana in their prison cells."The voters made quite clear their intention to avoid spending state and county funds prosecuting possession of less than an ounce of marijuana, and quite clear that they did not want to see adults suffer criminal convictions for possessing less than an ounce of marijuana," Sacramento County Assistant Public Defender Leonard Tauman said in an email. The appeals court "quite properly honored what the electorate passed."Attorney General Xavier Becerra's office said it is reviewing the ruling and did not say if he will appeal.RELATED: Nevada becomes first state to ban pre-employment marijuana tests"We want to be clear that drug use and sales within state prisons remains prohibited," said corrections department spokeswoman Vicky Waters. She said the department "is committed to providing a safe, accountable environment for prisoners and staff alike and we plan to evaluate this decision with an eye toward maintaining health and security within our institutions."The three-judge panel rejected the state's argument that guards will lose control over prisons if inmates are free to possess small quantities of marijuana, noting that possession can still be punished as a rules violation with longer prison terms or a reduction in privileges.While prison officials can still punish inmates for violating the rules, "this ruling will prevent inmates from having years added to their sentences for simple possession, reducing overcrowding and saving ,000-75,000 a year in unnecessary costs," said Assistant Public Defender David Lynch.RELATED: More than 100 illegal pot farms busted in Anza, tons of weed seizedThe judges scolded the attorney general's office for a counter-argument it said "uses arcane rules" and "twists the meaning of the words of the statute."Becerra's office argued that the court's reading of the law was absurd because it in effect allows controlled substances into prisons. But the court noted that it previously ruled that it's not illegal for inmates to have properly prescribed medications or medical marijuana behind bars — though it may be against the rules."The Attorney General raises the same hackneyed and losing arguments in each case involving contraband in jails or prisons," the judges wrote.Lawmakers held "an over abiding consensus" in the 1940s that drug use by inmates was "the ultimate evil," they wrote. But those old laws belie "a gradual change in attitude" first toward medical and eventually toward recreational marijuana."As a matter of public policy, his position may be sound," the judges wrote. "The fact that the Attorney General may not agree with the voters does not empower us to rewrite the initiative."They ultimately concluded that "a result is not absurd because the outcome may be unwise." 3667

SACRAMENTO, Calif. (AP) -- California Gov. Gavin Newsom says the state has signed a contract worth up to .4 billion with a company that will more than double the state's daily coronavirus testing capacity.Right now, California averages about 100,000 tests per day, with the state paying 0 per test and results taking between five and seven business days.Newsom said the state's new contract with Massachusetts-based PerkinElmer will increase the state's testing capacity to 250,000 per day by March 1 with each test costing about . Results would come within two days.The contract will initially cost the state 0 million, with a maximum amount of .4 billion. 678

SACRAMENTO, Calif. (AP) — Chemicals used for carpets and anti-stain products have been found in water sources for 7.5 million people in California, detailing the extent of the problem as state regulators work to develop safety levels for the contaminants that have been linked to cancer.A report released Wednesday by the Environmental Working Group found variants of the chemicals known as PFAS in 74 community water systems between 2013 and 2019, according to data from state and federal regulators. More than 40 percent of the systems had at least one sample that exceeded the health advisory level set by the U.S. Environmental Protection Agency.Communities served by systems with the highest detections of PFAS include Corona, Camp Pendleton, Oroville, Rosemont and areas of Sacramento.PFAS chemicals are used to make products water and stain resistant, including carpets, clothing, furniture and cookware. Two of the most well-known chemicals, PFOS and PFOA, have been phased out in the United States. But they don't break down easily and linger in the environment, earning the nickname "forever chemicals."RELATED: EPA: California homelessness causing poor water qualityStudies have linked PFOS and PFOA to a variety of health problems, including cancer, immune system issues and liver and thyroid problems. But there are thousands of variants of PFAS chemicals."One of the biggest takeaways here is we're not just detecting just PFOA and PFOS in these systems, but it's a mixture of different PFAS chemicals," said Tasha Stoiber, a senior scientist at the Environmental Working Group.California does not set maximum contaminant levels for PFAS chemicals or require water agencies to test for them. It does encourage water systems to test for them and offers guidelines on when they should notify the public. If agencies do test, they must report any samples that exceed the guidelines.RELATED: San Diego leaders present 0 million plan to solve Mexican sewage problemEarlier this year, Democratic Gov. Gavin Newsom signed a law allowing state water regulators to order more systems to monitor for PFAS chemicals and to notify the public. The law takes effect Jan. 1.Meanwhile, the State Water Resources Control Board is developing maximum contaminant levels for PFOS and PFOA. But those are just two of the thousands of variants of PFAS chemicals. Andria Ventura, toxic program manager at the advocacy group Clean Water Action, said setting standards for only two of the chemicals "sends the wrong message to the public."Ventura said she knows it is difficult to regulate for a class of chemicals this large, but "we need to start investigating how to do that, or how to at least get bigger chunks of these chemicals regulated."RELATED: San Diego Surfriders send 2,200 letters calling for Tijuana River clean-upWater systems have responded to the PFAS problem by taking wells offline, blending the contaminated water with cleaner sources and installing treatment systems.One of the highest concentrations of PFAS chemicals was found earlier this year in a well run by the California Water Service Company in Oroville. For every trillion parts of water, the sample contained 451 parts of six PFAS chemicals. That's more than six times higher than the EPA guidelines.Spokeswoman Yvonne Kingman said the company does not use the well to supply drinking water to its customers, but the company keeps the well online in case it needs the well for firefighters or as a backup should the main plant go offline. Kingman said the company tests for 14 types of PFAS chemicals.RELATED: EPA set to end California's ability to regulate fuel economy"The protection of our customers' health and safety is our absolute highest priority, so we've been monitoring this for quite a while," Kingman said.PFAS chemicals have been a problem near military bases because it is an ingredient in a foam the military uses to fight liquid fuel fires. A 2017 sample at a well in Camp Pendleton, the Marine Corps base in San Diego, contained seven PFAS chemicals for a combined 820 parts per trillion, or 11 times higher than the EPA guidelines.Camp Pendleton officials stopped using that well after the test, spokesman Capt. David Mancilla said. The base only uses the foam for emergencies, he said."The drinking water at MCB Camp Pendleton is safe to drink and meets or exceeds all regulated standards," he said. 4402
