Question: Does maternal metformin administration during pregnancy protect offspring auditory brainstem function after neonatal hypoxia-ischemia (HI)?
Finding: Maternal metformin prevented HI-induced hearing threshold elevation, preserved auditory brainstem response amplitudes, and partially rescued neuronal and oligodendrocyte lineage cells in the medial nucleus of the trapezoid body.
Meaning: Maternal metformin during gestation may serve as a prenatal neuroprotective strategy against neonatal hypoxic-ischemic brain injury. |
