Diagnostic abnormalities, disease severity and immunotherapy responsiveness in individuals with Down syndrome regression disorder.

Introduction: Down Syndrome Regression Disorder (DSRD) is a neuropsychiatric condition causing insomnia, catatonia, encephalopathy, and obsessive-compulsive behavior in otherwise healthy individuals with Down syndrome (DS). Smaller cohorts have identified heterogenous diagnostic abnormalities which have predicted immunotherapy responsiveness although pattern analysis in a large cohort has never been performed.

Methods: A multi-center, retrospective study of individuals with DSRD was performed.

Safety and Tolerability of Home Infusions in Down Syndrome Regression Disorder.

Purpose: Down syndrome regression disorder (DSRD) is a rare neuropsychiatric condition affecting otherwise healthy individuals with Down syndrome. Multiple studies on DSRD have revealed that immunotherapy with intravenous immunoglobulin (IVIg) is both safe and effective, although site of infusion has never been studied. This study sought to evaluate the safety and tolerability of IVIg in individuals with DSRD receiving home-based infusions.

Intraoperative Parathyroid Hormone Kinetics are Variable: An In-Vivo Analysis.

Objectives: Intraoperative parathyroid hormone (IOPTH) monitoring has become routine in parathyroid surgery to facilitate less invasive techniques to treat hyperparathyroidism. Despite this, little is known about in vivo IOPTH kinetics, which can greatly affect the reliability of its interpretation.

Methods: A prospective cohort of patients undergoing routine parathyroidectomy was studied.

Exercise-stimulated Resolvin Biosynthesis in Adipose Tissue is Abrogated by High Fat Diet-induced Adrenergic Deficiency.

Objective: Diet-induced white adipose tissue inflammation is associated with insulin resistance and metabolic perturbations. Conversely, exercise (Exe) protects against the development of chronic inflammation and insulin resistance independent of changes in weight; however, the mechanisms remain largely unknown. We have recently shown that, through adrenergic stimulation of macrophages, exercise promotes resolution of acute peritoneal inflammation by enhancing the biosynthesis of specialized pro-resolving lipid mediators (SPMs).
