“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

A 20-year-old Canadian is facing charges after he was allegedly asleep behind the wheel of a self-driving Tesla going more than 90 mph.The Royal Canadian Mounted Police were called on July 9 when witnesses saw a speeding Tesla electric car heading south of Edmonton, and what appeared to be no one behind the wheel.Both front seats were fully reclined and it appeared the driver and passenger were asleep, police told CBC.The car was going roughly 87 mph on a stretch of highway with a maximum speed of about 68 mph.A responding officer turned on their patrol car’s lights, as other cars on the highway pulled over, police say the Tesla automatically began to accelerate to more than 90 mph because the traffic in front of it was clearing."Nobody was looking out the windshield to see where the car was going," RCMP Sgt. Darrin Turnbull told CBC. "I've been in policing for over 23 years and the majority of that in traffic law enforcement, and I'm speechless. I've never, ever seen anything like this before, but of course the technology wasn't there."The driver was initially charged with speeding and had a temporary hold put on his license for sleeping behind the wheel. The RCMP decided recently to charge the driver with dangerous driving and set a December court date.Self-driving features usually require input from the driver every so often to ensure someone is paying attention while the car is in motion. However, CTV reports there are after-market products that can interfere with that system."Although manufacturers of new vehicles have built in safeguards to prevent drivers from taking advantage of the new safety systems in vehicles, those systems are just that — supplemental safety systems," said Superintendent Gary Graham of Alberta RCMP Traffic Services in a statement. "They are not self-driving systems, they still come with the responsibility of driving."Quebec and Ontario have approved pilot projects for autonomous cars on their roadways. 1973

A 19-year-old died after inhaling deodorant spray to get high, according to a new case report, and doctors who treated the man in the Netherlands are using the case to highlight the fatal consequences of inhaling chemicals.Such cases are "very rare," according to Dr. Kelvin Harvey Kramp of Maasstad Hospital's intensive care unit in Rotterdam.Kramp explained that because deaths from deodorant inhalation are not common among the general population, the "consequences aren't really known," causing people to continue this dangerous behavior.The patient, who had a history of psychotic symptoms, had been admitted to a rehabilitation center for cannabis and ketamine abuse and was taking antipsychotic drugs.During a relapse in July, he placed a towel over his head and inhaled deodorant spray to get high, according to the report, published Thursday in the BMJ. He became hyperactive, jumping up and down, before blood flow stopped suddenly, causing him to go into cardiac arrest and collapse, the report says. He was admitted to the hospital and placed in a medically induced coma when staff failed to revive him.The "patient did not had enough brain function to sustain life," Kramp said. Nine days after he was admitted, doctors withdrew care, and the man died.There are three theories about what caused the cardiac arrest, Kramp said: The inhalant could have oversensitized the patient's heart, which can make any subsequent stress, like getting caught by a parent, cause cardiac arrest. Also, inhalants decrease the strength of contraction of the heart muscle. Another possibility is that inhalants can cause spasm of the coronary arteries.The patient's hyperactivity could mean he was experiencing a "scary hallucination," Kramp said, adding that if that was the case, the first theory would be applicable.Solvent abuse is not a new phenomenon, the report points out, and is primarily found in "young and vulnerable people," according to Kramp.The group most affected by solvent abuse is 15- to 19-year-olds, studies show. People in rehabilitation centers or prisons are more likely to abuse household products, the report added, meaning there could be a greater risk of cardiac deaths in these environments.In these secure environments, people have less access to other substances, and household products are easily available, explained Roz Gittins, director of pharmacy at the British drug charity Addaction, who was not involved in the report.The toxic chemical butane, often used in sprayable household products, has a similar effect to alcohol, Kramp said. "The intention of abusers is to experience feelings of euphoria and disinhibition."Other health effects of inhalants include liver and kidney damage, hearing loss, delayed behavioral development and brain damage.Chemicals like butane have a very quick and short-acting effect, which can make people want to take more, Gittins said.The report's authors hope increased awareness will help reduce further inhalant-related deaths, through education in schools around the fatal consequences of solvent abuse."To stop the abuse, we can only try to increase awareness about the possible dramatic consequences of inhalant abuse among youngsters, parents, medical personnel," Kramp said.Up to 125 deaths are caused by inhalant abuse every year in the United States, according to the report.Stephen Ream, director of UK-based charity Re-solv, said that in 2016, "there were 64 deaths associated with these products," with butane gas accounting for at least a third of those."The breakdown by product is more difficult to establish, but we would suspect that about four or five deaths a year are associated with aerosol products," he said."Solvent abuse is also more of a problem in the northern regions of the UK, with rates particularly higher in Scotland and the North East of England."According UK drug advice organization Talk to Frank, more 10- to 15-year-olds were killed from abusing glues, gases and aerosols than from illegal drugs combined between 2000 and 2008. 4074
