The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review.
Patients hospitalized with COVID-19 whose blood flows less freely than normal are at higher risk of death from complications, a U.S. study showed. The findings indicate that measurement of blood viscosity, or blood thickness, should be a regular part of these patients' medical work-up, the researchers said.High blood viscosity impairs flow to small vessels and increases the risk of blood clots, the researchers noted in the study published on Monday in the.
"This study demonstrates the importance of checking for blood viscosity in COVID-19 patients early in hospital admission, which is easily obtained through routine lab work," Dr. Robert Rosenson of the Mount Sinai Health System said in a statement. His team called for further studies to see whether measures to reduce blood viscosity, such as treatment with blood thinning drugs, would be helpful.
"Any child who experiences potential anaphylaxis following vaccination should absolutely be evaluated," study leader Dr. Joel Brooks of Children's National Hospital in Washington said in a news release. "The benefits and risks must be weighed carefully when it comes to a second dose.
