Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

Inter‐eye microvascular asymmetry across stages of diabetic retinopathy: An OCT angiography study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate inter‐eye asymmetry in macular microvascular parameters across different stages of diabetic retinopathy (DR) using OCT angiography, and to explore the associations with clinical factors. Methods This cross sectional study included 442 eyes of 221 patients with diabetes mellitus type 2. Central subfield thickness (CST), area

Longitudinal progression of retinal nonperfusion in clinically stable diabetic retinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To longitudinally assess and quantify changes in retinal nonperfusion (NP) in clinically stable diabetic retinopathy (DR) using ultra‐widefield fluorescein angiography (UWF‐FA) and optical coherence tomography angiography (OCTA). Methods Fifty‐one eyes from thirty‐three patients were followed for a mean of 15.9 ± 11.4 months.
