Higher Level of RBC Transfusion may Not Have Efficacy for Anemia by Karishma Abhishek on January 3, 2021 at 5:13 AM
However it is shown that using a higher level (threshold) of red blood cells (within clinically accepted limits) when ordering a transfusion, offers no advantage in survival or reduction in neurological impairment over a lower threshold, as per a National Institutes of Health-funded large, multi-centre randomized clinical trial study to-date on comparison of thresholds for blood transfusions in premature babies, published in The New England Journal of Medicine.
Preterm infants born before 29 weeks of pregnancy with weight less than 1,000 grams (slightly more than 2 pounds) are at high risk for anemia because of their early stage of development, reduced ability to produce red blood cells, and need for blood sampling as part of their intensive medical care.
Print article LOS ANGELES The aim of the vaccination campaign against COVID-19 is herd immunity the point at which so few people are susceptible to infection that the virus runs out of places to go. In the early days of the pandemic, epidemiologists estimated that would require inoculating about two-thirds of the U.S. population. Now many of those same experts say that figure is almost certainly too low. “If you really want true herd immunity, where you get a blanket of protection over the country … you want about 75 to 85% of the country to get vaccinated,” Dr. Anthony Fauci, the nation’s top infectious-disease official, told a reporter last week. “I would say even closer to 85%.”
