Extending sleep to improve glycemia: The Family Routines Enhancing Adolescent Diabetes by Optimizing Management (FREADOM) randomized clinical trial protocol.

Sleep deficiencies amongst individuals with type 1 diabetes mellitus (T1DM) have been linked with dysregulated glycemic control and greater morbidities. Sleep extension (EXT) has been identified as a viable intervention target to improve adolescent outcomes. The intervention aims to emphasize collaborative work with families to engage in behaviors that increase the likelihood of the youth increasing their sleep duration consistently.

A Prolonged QTc Interval Leads to the Diagnosis of Hyperthyroidism in an Adolescent Boy.

Background: Syncope is a common cause of pediatric emergency department visits and carries a broad differential diagnosis, which includes a few rare but critical cardiac conditions.

Case Report: We review the case of an adolescent boy who presented to the emergency department after a syncopal event. He was found to have a prolonged QTc interval on electrocardiogram (ECG), without personal or family history or known risk factors.

Increased length of stay and hospital charges in adolescents with type 1 diabetes and psychiatric illness.

Objectives: Type I diabetes mellitus (T1DM) is one of the most common chronic diseases of childhood. Diabetic ketoacidosis (DKA) in this population contributes to significant healthcare utilization, including emergency room visits, hospitalizations, and ICU care. Comorbid psychiatric illnesses (CPI) are additional risks for increased healthcare utilization.

Differences in sleep architecture according to body mass index in children with type 1 diabetes.

Slow wave sleep (SWS), or deep sleep, is thought to be the most restorative stage of sleep and may be of a particular interest in the pathophysiology of obesity. The aim of this study was to investigate differences in sleep architecture based on body mass index (BMI) among a pediatric population with type 1 diabetes mellitus (T1DM). We hypothesized that children with T1DM who are obese would have less SWS than those who are not obese.

Acetylation of prostaglandin H2 synthases by aspirin is inhibited by redox cycling of the peroxidase.

Aspirin exerts its unique pharmacological effects by irreversibly acetylating a serine residue in the cyclooxygenase site of prostaglandin-H2-synthases (PGHSs). Despite the irreversibility of the inhibition, the potency of aspirin varies remarkably between cell types, suggesting that molecular determinants could contribute to cellular selectivity. Using purified enzymes, we found no evidence that aspirin is selective for either of the two PGHS isoforms, and we showed that hydroperoxide substrates of the PGHS peroxidase inhibited the rate of acetylation of PGHS-1 by 68%.
