U.S. nursing homes still face delays in COVID-19 testing; you can wash Halloween candy



(Reuters)-The following is a summary of the latest scientific research on the new coronavirus, as well as efforts to find a cure and vaccine for the disease COVID-19 caused by the virus.

U.S. nursing homes cannot get a timely COVID-1

9 diagnosis

Researchers reported in the Journal of the American Medical Association (JAMA Internal Medicine) on Friday that most nursing homes in the United States are still unable to obtain timely COVID-19 test results from employees and residents. They received answers to the following questions from more than 15,000 skilled nursing agencies: In the past two weeks, how long did you spend on average getting COVID-19 test results? Only 14% said they got the most reliable virus test result in less than a day, while 40% said it would take at least three days to get the result. The co-author of the study, Dr. Michael Barnett of Harvard University’s Chenhe School of Public Health, said “this is an unacceptably slow transition.” He said, “Even in hotspot counties where the federal government provides rapid testing machines, this is true. This means that these machines cannot help nursing homes achieve the required rapid turnover.” He pointed out that nursing homes accounted for the US COVID-19 deaths More than 40% of the number. “Our results show that although this vulnerability has been known for a long time, nursing homes still lack the basic ability to effectively screen personnel to prevent a new COVID-19 outbreak.” (bit.ly/2HLYFMQ)

You can wash Halloween candy to reduce the risk of infection

Researchers reported on mSystems on Thursday that the risk of catching COVID-19 on Halloween can be reduced to a certain extent by simply washing hands with candies. In the accompanying press statement, they recommend mixing three ounces (85 grams) of dish soap containing sodium lauryl sulfate or SLS (sometimes called sodium lauryl sulfate or SDS) per gallon of water (3.8 liters) , And then submerge the candy to cover all surfaces of the wrapping paper. After immersing in water for at least one minute, rinse the candy with clean water. To test this method, they asked 10 recently diagnosed COVID-19 patients to use typical individually packaged Halloween candy. When the candies were not washed later, the researchers found that 60% of the candies without washing their hands or deliberately coughing contained the virus. They found that washing the candy with dish soap can reduce the virus load by 62%. Rodolfo Salido of the University of California, San Diego said in a news article that although cleaning Halloween candy “is reasonable if someone wants to be extra careful… the main risk of treating COVID-19 during trick-or-treating is airborne”, released.

When COVID-19 changes from mild to moderate, the immune response changes

Researchers reported in Cell on Wednesday that the immune response to the new coronavirus has changed dramatically as patients transition from mild to moderate illness, which has an impact on patient care. James Heath, a co-author of the Seattle Institute for Systems Biology, said: “Moderate disease (hospitalized but not intubated) is very different from mild disease… but very similar to severe disease,” the team’s researchers studied The level of 139 patients with poor severity of COVID-19 was determined. Heath explained that once a COVID-19 patient suffers from a moderate illness, “a strong inflammatory signal will prompt the body to produce a strong response.” “However, the severe consumption of nutrients in the blood provides the raw material for establishing this response,” And “abnormal and dysfunctional immune responses began to appear, increasing with increasing severity.” He said that this is also true in severe diseases, but even more so. The results of the study indicate that new drugs should be tested in patients with chronic illnesses. Heath said: “It is easier to treat patients at that stage because they are more likely to respond.” In addition, he said, the consumption of nutrients in the blood suggests that non-drugs, such as dietary supplements, may help these patients. reaction.

Wearable sensors may improve recognition of COVID-19

A new study shows that wearable fitness equipment can one day help detect early or mild cases of COVID-19. More than 30,000 people from all over the United States voluntarily use the smartphone app, which collects smartwatch and activity tracker data on heart rate, sleep and activity levels, as well as self-reported symptoms and diagnostic test results. Overall, there were 3,811 reported symptoms. Most people were not tested for coronavirus, but 54 of them tested positive and 279 tested negative. Co-author Giorgio Quer, author of Scripps Research Translational, said: “The team was able to determine with approximately 80% prediction accuracy whether a person reporting symptoms may have COVID-19.” California La Jolla Institute. Participants can use Fitbit devices, Apple HealthKit or Google Fit to connect to their data. The researchers said in a report on Thursday in Natural Medicine: “As the depth and diversity of data types from personal sensors continue to expand, the ability to detect subtle changes in early (infection) responses will potentially improve.” Quer added: “Early identification of those who are symptomatic or even asymptomatic is particularly valuable because people may be contagious during this period.” “That is the ultimate goal.” (go.nature.com/3kKVVxP)
