Do pupil damage after periorbital laser treatment of a port-wine stain?
We recommend that both patients and operators use protective eyewear with every laser procedure. When treatment is administered near the eye, eye shields should be placed behind the eyelid or a safe distance should be maintained between the laser and the eyeball by treating up to the orbital rim only.
These findings provide the first evidence of racial differences in placental telomere length. Telomere length was significantly shorter in placental samples from black mothers compared with white mothers. Given previous studies that have reported that telomere length, cellular senescence, and telomere dynamics are molecular factors that contribute to the rupture of the amniotic sac, onset of labor, and parturition, our findings of shorter telomere length in placentas from black mothers suggest that accelerated cellular aging across placental tissues may be relevant to the increased risk of preterm delivery in black pregnancies. Our results suggest that racial differences in cellular aging in the placenta contribute to the earliest roots of health disparities.
