Foveal Avascular Zone development by OCTA: weighing the influence of Gestational Age and neonatal early growth independently of Retinopathy of Prematurity.

Purpose: Focusing the premature birth and its potential complications, this study analyzes Foveal Avascular Zone (FAZ) measured by Optical Coherence Tomography Angiography (OCTA) and its correlation with the severity of prematurity and neonatal growth.

Methods: A cross-sectional comparative study was performed, involving 71 children school-age with history of prematurity and a full-term children control group. Several variables from the neonatal period were collected, such as Gestational Age (GA), Birth Weight (BW), initial Weight Gain (WG) and Retinopathy of Prematurity (ROP).

SATB2 as a Marker of the Proximal Nephron: Expression in Nephrogenic Adenoma and Correlation With Other Renal Tubular Markers.

Nephrogenic adenoma (NA) is an infrequent reactive urothelial lesion. The expression of immunohistochemical renal tubular markers has been reported in NA, although a proximal or distal nephron phenotype has not been established. Special AT-rich sequence-binding protein 2 (SATB2) is a marker of a colorectal origin of adenocarcinomas, occasionally reported in renal samples.
