Alzheimer’s risk gene undermines insulation of brain’s “wiring”

The APOE4 gene variant increases the risk of Alzheimer's disease by disrupting the insulation of brain wiring. Research found that oligodendrocytes mismanage cholesterol, failing to transport fat molecules to myelinate axons. This deficiency may contribute to the pathology and symptoms of Alzheimer's.

Treatment guidelines for children hospitalized with COVID-19 were rapidly but not completely followed

A study of 18,364 children hospitalized with COVID-19 found that pediatricians prescribed medications in accordance with guidelines in only 55-82% of cases. The use of recommended medications quickly increased after national guidelines were released in 2020, but compliance remained lower than expected.
