On December 26, the official website of Imperial College London published an article summarizing the review - researchers from this world-renowned university have continued to issue warnings about the truth about the new crown through professional research in 2022. Looking at this information that has been forewarned for a long time now, it can't help but make people feel even more emotional. Brother Sanshui specially edited it as follows for your friends to read.
1, Omicron infection does not boost immunity
A study published in the journal Science found that Omicron infection boosted immunity to previous variants, such as alpha, , delta, and the original strain, but to a lesser extent , Omicron , in people who received the triple vaccine for the first time. People who were previously infected with a different variant did not see any improvement at all. The Imperial College research team behind the paper attributed this to an effect called "hybrid immune damping." The study helps explain why so many people who received the triple vaccine became infected or reinfected during the Omicron epidemic earlier this year.
2, Blood oxygen monitoring helps spot warning signs
Researchers at Imperial College London have found that measuring blood oxygen levels can help identify early signs of deterioration in patients with COVID-19. Blood oxygen can be measured using a pulse oximeter, a widely available, inexpensive device that shines light through a person's finger to assess blood oxygen levels. Declining blood oxygen levels may indicate that a patient's health is deteriorating and that they require further intervention.
3 COVID-19's impact on the brain is equivalent to 20 years of aging
Researchers from Imperial College London and Cambridge University analyzed cognitive data from 46 people who had been hospitalized with COVID-19 and found that they performed worse on tests measuring memory, attention and reasoning skills. The researchers compared their results with population-level data and found that the decline in performance was comparable to the effects of 20 years of aging. Researchers say the body's own inflammatory response is likely the main cause of the damage.
4 COVID-19 and influenza can be a dangerous combination
Patients who have both COVID-19 and influenza are at a much greater risk of severe illness and death than patients who have COVID-19 alone. A team of researchers from the University of Edinburgh, the University of Liverpool, Leiden University and Imperial College London analyzed data from more than 305,000 COVID-19 patients. They found that hospitalized patients with both COVID-19 and influenza were more than four times more likely to need ventilation and 2.4 times more likely to die than patients with COVID-19 alone. This highlights the need for more influenza testing in COVID-19 patients, as well as the importance of comprehensive vaccination against both diseases.
5, COVID-19 may cause complications in children
In the early stages of the pandemic, researchers from the Department of Infectious Diseases at Imperial College London discovered a rare syndrome affecting children that they called pediatric inflammatory multisystem syndrome (PIMS). PIMS is similar to another rare inflammatory syndrome called Kawasaki disease. Through a study called PreVAIL, researchers were able to identify unique genetic signatures in children with PIMS. The researchers also confirmed the importance of close monitoring and early treatment in slowing the inflammatory process and reducing risk.
6 Genetic factors influence your likelihood of severe COVID-19
Researchers at Imperial College London have found that common genetic changes can reduce the risk of severe COVID-19. TMPRSS2 is a protein found on cells in many tissues throughout the body and is required to activate the SARS-Cov2 spike protein and allow virus to enter cells. About a quarter of the population has a variant of this protein, and research from Imperial College London published in Translational Medicine Research in February found that people with this variant were much less likely to be hospitalized with COVID-19.
7, COVID-19 vaccination may slightly affect menstrual cycle
html Two studies in early 2000 found that while the vaccine could have some impact on the menstrual cycle, the impact was small and faded quickly. The studies come from the United States and Norway, where vaccinations are administered three to four weeks apart, compared with eight weeks in the United Kingdom. The researchers described the results as "limited but reassuring."8, Vaccines may have prevented nearly 20 million deaths from COVID-19
Research modeling from Imperial College London found that vaccination could prevent 19.8 million COVID-19 deaths worldwide in the first year of vaccine rollout. Researchers at Imperial College London's MRC Center for Global Infectious Disease Analysis were able to arrive at the figure using excess death data from 185 countries and territories around the world. But anti-vaccination messages on social media are actually hindering the speed and uptake of vaccines.
