(KGTV) — Vista Unified School District is postponing the in-person reopening of two high schools after learning that hundreds of students attended at least two Halloween parties last month.A letter from district and school officials to parents said that students from Vista High School and Mission Vista High School attended two large parties over the weekend and didn't practice social distancing or mask requirements.Because of the reported parties, VUSD said it will reschedule the reopening of in-person classes at both schools until Monday, Nov. 16. Mission Vista High was scheduled to resume in-person classes on Nov. 9, and Vista High was set to do the same on Nov. 12.RELATED: Several Vista Unified schools back to online learning after positive COVID-19 cases reported"At this time, we have legitimate concerns about the health and safety of the students who attended these large Halloween gatherings and the safety of all students and staff members if they return to in-person learning as scheduled..." the district's letter read.Officials urged parents to have their children tested for COVID-19 if they attended either party.Since Sept. 8, the district has reported 25 coronavirus cases among students and staff at its schools, including three cases at Vista High and two cases at Mission Vista.Vista Unified Superintendent Dr. Matthew Doyle said in a community update that the county is working with officials to go over any concerns and progress to resume in-person learning: 1497

“Today I'm donating convalescent plasma,” Judy Lutkin said.“This will be my third time donating.” Lutkin had COVID-19 back in April. “I was pretty sick for about four or five days,” she said. Now she comes infrequently to donate plasma. “It doesn't hurt. It doesn't feel bad. It’s fairly easy.”Plasma is just one of the tools used in fighting coronavirus. As it gets donated, it goes to COVID patients.Since early April, when Vitalant started collecting these donations, they’ve collected more than 9,700 donations equaling more than 33,000 units.“You could help as many as five patients with one sitting,” Liz Lambert, Vitalant spokesperson, said.Vitalant is a nonprofit that collects blood for about 1,000 hospitals across the country.“Right now, there's an emergency need for convalescent plasma as we anticipate more patients will be getting that treatment, or hospitals will be wanting to use that treatment,” Lambert said.The FDA issued an emergency use authorization for convalescent plasma as a potential COVID-19 treatment in late August. Convalescent plasma is taken from the blood of someone who’s already contracted a particular illness, in this case, COVID-19.This isn’t the first time in history; it’s been used to treat a virus.“Convalescent plasma is a very historic and crude way of conferring so-called passive immunity to patients who have a viral or bacterial disease,” Doctor Phil Stahel, Chief Medical Officer at the Medical Center of Aurora, said.So far, this center has treated 100 COVID-19 patients using this method.“Studies have shown that convalescent plasma is very safe,” he said. “It has been recently used for Ebola and other viral diseases for which we do not have a vaccination.”Doctor Stahel said patients they treat who are significantly sick could recover within 24 to 48 hours.Here’s how it works.“Antibodies are proteins that we form in our blood that attack antigens once our immune system recognizes them. It takes weeks for these to develop,” Doctor Ralph Vassallo, Chief Medical & Scientific Officer for Vitalant, said.The antibodies are taken from a recovered patient and put in a patient who recently contracted the disease.“The idea of convalescent plasma is to give them, in that period, when the patient does not have their immune response, to help neutralize the virus and prevent it from infecting cells in the body,” Doctor Vassallo said. “Convalescent plasma has been used for over 100 years in respiratory infections, including influenza.”With more hospitals using convalescent plasma to help COVID-19 patients, blood donation centers hope to identify more plasma donors who have recovered from the virus.“Whether its blood or convalescent plasma, there is a constant need,” Lambert said.Vitalant checks every regular blood donor for the antibodies as well, in hopes of identifying more possible donors.“In the first couple of September, it’s been about 3.6% nationwide,” Dr. Vassallo said.Those interested in donating convalescent plasma need to meet the same requirements as a blood donor, like being 16 years old or older, and at least 110 pounds.However, they also need to have a doctor-referred case of COVID-19 or doctor-referred antibody test.“It is indeed the first line of defense, and we should treat those patients early. This is for the adult in patients who are severely sick and at risk of getting on a ventilator, which we try to avoid by all means,” Doctor Stahel said. 3450

(KGTV) — Several storms that have showered California with snow and rain have lifted the state out of drought for the first time since 2011.The U.S. Drought Monitor said Thursday that California was free of drought for the first time since Dec. 20, 2011. The state had seen some form of drought for at least 376 consecutive weeks.As of Thursday, the agency said more than 93 percent of the state was out of drought conditions. RELATED: Devastating 'ARk' storm envisioned for California by U.S. Geological SurveyAmong the areas still seeing "abnormally dry" conditions are a small patch along California's border with Oregon and parts of four Southern California counties, including San Diego County. San Diego County's drought conditions were due to abnormally dry years prior to this winter, according to the agency, and local reservoirs were not at capacity despite the heavy rains."The rest of the region in Southern California is still abnormally dry due to very dry previous years. Reservoirs in San Diego County are only at 65 [percent] capacity. Big Bear Lake was down 18 feet in early March, although expected to continue to rise," the agency says.RELATED: Recent rain not enough to bring San Diego out of droughtLocally, weather is expected to continue warming into next week, after the region saw more rain and snow last weekend. 1347

(KGTV) - While support for medical marijuana is speeding up on a state level and in nationwide opinion polls, federal advancement is slowing due to research and approval gridlock. There’s no denying the popularity of marijuana in the United States, with THC and cannabis products approved for medical use in 33 states. Recreational use is supported in 11 states, including California. The election results are echoed in a 2016 Quinnipiac University poll which showed 81 percent of Americans support medical marijuana legalization. California's support of medical marijuana started more than two decades ago when voters passed Proposition 215, the “Compassionate Use Act of 1996.” Laws calling for regulation of medical marijuana were passed in 2015 and 2016, with recreational marijuana becoming legal in 2018. While voters increasingly approve marijuana legalization in various states across the country, the federal government has been slower to grant permission for use. RELATED: Timeline: How marijuana laws have changed in California In 1970, the Drug Enforcement Agency rated marijuana as a Schedule I controlled substance, defined as having a high potential for abuse with no accepted medical use for treatment. Almost 50 years later, the Federal Drug Administration has not approved marketing cannabis for the treatment of any condition. However, four cannabis derived or related products have been approved for use with a prescription from a licensed healthcare provider. Epidiolex contains a purified form of CBD for treating seizures associated with Lennox-Gastaut or Dravet syndrome in patients as young as 2 years old, according to the FDA. Also approved by the agency are Marinol and Syndros, used for treating weight loss in AIDS patients. RELATED: Judge: California child can take cannabis drug to school In order to approve drugs, the FDA relies on applicants and scientific investigators to conduct research. “The FDA is aware that several states have either passed laws that remove state restrictions on the medical use of cannabis and its derivatives or are considering doing so. It is important to conduct medical research into the safety and effectiveness of cannabis products through adequate and well-controlled clinical trials,” FDA officials report. The agency said it supports medical marijuana research by providing information about the process to conduct the research and requirements needed to develop a cannabis-derived drug, supporting developers through meetings and regular interactions, and providing general support.

In 2017, the National Institutes of Health supported 330 projects focusing on therapeutic properties of cannabinoids and CBD. 2826
