(Reuters) – The following is a summary of recent studies on COVID-19. They include studies that require further study to confirm the findings and have not yet been confirmed by examination.
Diabetes increases the risk of chronic COVID
A new analysis of seven previous studies has shown that diabetes increases the risk of long-term COVID.
The researchers reviewed studies that monitored people for at least four weeks after recovery from COVID-19, in which people developed persistent COVID-related symptoms such as cerebral palsy, skin diseases, depression, and shortness of breath. According to the presentation https://eppro02.ativ.me/web/page.php?page=IntHtml&project=, in three studies, people with diabetes were four times more likely to develop long-lasting COVID than people without diabetes. ADA22 & id = 1683 At the annual scientific sessions of the American Diabetes Association on Sunday. According to the researchers, diabetes appears to be a “strong risk factor” for long-term COVID, but their findings are predictive because patients used different methods, longer COVID definitions and follow-ups, while some were hospitalized and others focused on people. with easier COVID-19 cases.
“More qualitative research on multiple populations and conditions is needed to determine if diabetes is indeed a risk factor,” the researchers said. “At the same time, careful monitoring of people with diabetes … may be recommended” after COVID-19.
COVID-19 during pregnancy is associated with infant learning skills
Researchers have found that babies born to mothers infected with COVID-19 during pregnancy may have a higher risk of developing brain problems than the average.
They studied 7,772 babies born in Massachusetts between March and September 2020 and followed them for up to 12 months. During this time, neuronal developmental disorders were detected in 14.4% of infants born to 222 women who tested positive for coronavirus during pregnancy, and in 8.7% of infants whose mothers escaped the virus during pregnancy. Taking into account other risk factors for neurodevelopment, including preterm birth, SARS-CoV-2 infection during pregnancy was 86% higher in the diagnosis of hereditary neuronal developmental disorders, the researchers said Thursday at the JAMA Network Open https: // jamanetwork .com / journals / jamanetworkopen / fullarticle / 2793178. When an infection occurs in the third trimester, the risk doubles.
Researchers say that their research is short-lived and does not rule out the possibility that additional neurodevelopmental effects may become apparent as children grow older. On the other hand, they point out that greater and more rigorous research is needed to rule out other potential causes and prove the coronavirus is to blame.
COVID-19 syndrome, which is rare in children, is now less common
According to a new study, a rare but life-threatening inflammatory syndrome observed in some children after coronavirus infection has become even rarer with the Omicron variant, which causes most infections and children are vaccinated.
Researchers examined more than half a million children and adolescents from Denmark who became infected after Omicron dominated, about half of whom became infected after vaccination. Overall, only one vaccinated child and 11 unvaccinated children developed Multisystemic Inflammatory Syndrome (MIS-C), which causes inflammation of the heart, lungs, kidneys, and brain after a mild or asymptomatic SARS-CoV-2 infection. This represents 34.9 MIS-C cases per million children unvaccinated with COVID-19 and 3.7 cases per million young COVID-19 patients vaccinated, the researchers said at JAMA Pediatrics on Wednesday https://jamanetwork.com/journals/jamapediatrics/ fullarticle / 2793024 . For comparison, the level of Delta-dominated MIS-C cases was 290.7 per million uninfected infected children and 101.5 per million vaccinated with COVID, they said.
According to the researchers, the risk of MIS-C in vaccinated children is much lower, and this vaccine helps to protect the immune system from developing a fatal inflammatory reaction, which is a sign of MIS-C.
