CHILDHOOD BLINDNESS FROM SURGE OF ADVANCED STAGE RETINOPATHY OF PREMATURITY IN PREMATURE INFANTS DURING THE COVID-19 PANDEMIC: A CASE SERIES

Childhood blindness from surge of advanced stage retinopathy of prematurity in premature infants during the COVID-19 pandemic: a case series

Background Retinopathy of prematurity (ROP) is a proliferative disease of the ocular retinal vasculature in premature infants, being a leading cause of preventable childhood blindness.The COVID-19 pandemic serves as an additional barrier to access to care and referral, potentially leading to more cases of advanced stage ROP.Although surgery can be

Crossing beyond scattering amplitudes

Abstract We find that different asymptotic measurements in quantum field theory can be related to one another through new versions of crossing symmetry.Assuming analyticity, we conjecture generalized crossing relations for Breast Pump multi-particle processes and the corresponding paths of analytic continuation.We prove them to all multiplicity at
