Question: Is low caregiver health literacy associated with higher pediatric emergency department use and nonurgent visits?
Answer: Over half of caregivers presenting with their children to the ED have low health literacy. Low caregiver health literacy is an independent predictor of higher ED use and use of the ED for nonurgent conditions. In children without a chronic illness, low health literate caregivers had more than 3 times greater odds of presenting for a nonurgent condition than those with adequate health literacy.
yes

Question: Is fractional urinary excretion of IgG the most powerful predictor of renoprotection by ACE inhibitors in IgA nephropathy?
Answer: Renoprotection by ACEi is a multifactorial phenomenon: the best predictor of renoprotection is FEIgG, a marker of disruption of glomerular barrier to proteins; renoprotection depends not only on ability to reduce proteinuria, but probably also on antiinflammatory and antifibrotic activity.
yes
