The following is COVID- A summary of some recent studies on 19. They require further research to support the findings and include studies that have not yet been certified by peer review.
Epstein-Barr virus may play a role in some long COVID cases
COVID-19 reactivates a common virus not found in most people The effects may increase a patient's specific long-term risk-persistent symptoms, according to preliminary findings from the study. Over 90% of adults are infected with Epstein-Barr virus (EBV). Most remained asymptomatic, but some developed mononucleosis as adolescents or young adults.
Of the 280 patients with SARS-CoV-2 infection, researchers, including 208 with long COVIDs, had fatigue and thoughts four months after diagnosis. Participants with immune cells in the blood have shown signs of recent EBV reactivation that have found that the problem of reasoning is more common in the study. However, these signs of reactivation were not associated with other long COVID findings, such as gastrointestinal, heart, or lung problems. Also, EBV itself was not detected in the patient's blood. This suggests that reactivation is temporary and can occur during acute COVID-19. Dr. Timothy Henrich and colleagues at the University of California, San Francisco, medRxivhttps://www.medrxiv.org/content/10.1101/2022.06.21.22276660v1について報告しました。 before the peer review.
The findings do not prove that EBV reactivation caused the patient's symptoms, Henrich said. And even so, "many other long-term COVID symptoms, such as the long-term intra-tissue persistent SARS-CoV-2 virus and the dysregulated immune system that can result from the persistent virus. There is likely a cause, "he said. "Further research on various tissues is urgently needed, as well as studies that follow participants months or years after acute infection."
SARS-CoV-2 May impair the processing of blood glucose by the organs
Coronavirus infection impairs the activity of multiple genes involved in the body's chemical processes, including blood glucose metabolism. Researchers of the time have seen these effects not only in the patient's respiratory tract, but also elsewhere in the body.
Japanese researchers analyze blood and tissue samples from patients with mild or severe COVID-19 and healthy volunteers and "express" the genes that control them. Or the activity level was evaluated. Called the insulin / IGF signaling pathway, it affects many physical functions required for metabolism, growth and fertility. "The results were impressive," said Ichiro Shimomura, a research leader at Osaka University, in a statement. "SARS-CoV-2 infection affected the expression of insulin / IGF signaling pathway components in lung, liver, adipose tissue, and pancreatic cells." The resulting disruption of blood glucose metabolism is COVID to organs. The researchers said they were likely to contribute to the effects of -19.
Partially due to the inflammatory response of the immune system to the virus was more pronounced in patients with severe COVID-19, they journal Metabolismhttps://www.metabolismjournal.com/article/S0026-0495(22)00114-7/fulltext.で報告しました。試験管実験では、COVID-19の入院患者に利益をもたらすことが知られているデキサメタゾンが、遺伝子に対するウイルスの悪影響を和らげるのに役立ちました。.
New discoveries show that some patients develop metabolic complications such as insulin resistance, hyperglycemia, hyperlipidemia, and new onset of diabetes during or after COVID-19. Researchers said it could be a clue to the reason.
New data supports 5 days of quarantine and 5 days of masking
New studies now require a 5 day quarantine period for COVID-19 infection According to researchers, rigorous masking continued for five days to prevent infection from cases that remained culturally positive.
Researchers at the University of Boston School of Medicine have found at least 92 vaccinated college students and staff infected with the delta or omicron variant of coronavirus to analyze with PCR and certain rapid antigens. A home-use test that collected nasal swabs daily for 10 days. Only 17% of these young, healthy adults tested positive after 5 days, and no one was infected more than 12 days after the onset of symptoms, the researchers said. Reportedhttps://academic.oup.com/cid/advance-article/doi/10.1093/cid/ciac510/6614634.。報告書によると、ステータス、および陰性の迅速抗原検査は非常に信頼できました。
Rapid antigen testing "may provide reassurance for lack of infectivity ... Prevents infection from 17% of individuals who remain culture positive after quarantine. It takes a full 10 days to complete, "stated research leader Dr. Tara Bouton.
