Sleep disruption in patients with active and treated endogenous Cushing's syndrome.

Context: The hypothalamic-pituitary-adrenal axis is a critical regulator of circadian rhythm in humans. Impaired sleep adversely affects metabolic, emotional, and cognitive health.

Objective: To characterize sleep disturbances in patients with active and treated Cushing's syndrome (CS), and identify factors associated with impaired sleep in treated patients.

Voxelotor improves red blood cell functionality in children with sickle cell anaemia: An ancillary study of the HOPE-KIDS 1 trial.

Introduction: Sickle haemoglobin (HbS) polymerisation perturbs red blood cell (RBC) rheology and drives sickle cell disease (SCD) pathophysiology. Voxelotor is an HbS polymerisation inhibitor that increases haemoglobin (Hb)-oxygen affinity.

Methods/results: In this 48-week, prospective, single-centre translational study, 10 children aged 4-11 years with SCD were treated with voxelotor.

Suture Fixation to Reduce Graft Detachment in Descemet Stripping Endothelial Keratoplasty.

Purpose: The aim of this study was to report the outcomes of graft fixation using interrupted, full-thickness sutures on graft detachment after Descemet stripping endothelial keratoplasty (DSEK).

Methods: All DSEK procedures performed at Mayo Clinic, Rochester, MN, from 2015 through 2022 were retrospectively reviewed. Risk factors for graft detachment were defined as previous incisional glaucoma surgery, previous penetrating keratoplasty, or absence of the normal lens-capsule barrier.
