Development and Validation of an Anion Exchange High-Performance Liquid Chromatography Method for Analysis of Empty Capsids and Capsids Encapsidating Genetic Material in a Purified Preparation of Recombinant Adeno-Associated Virus Serotype 5

The development of various manufacturing platforms and analytical technologies has substantially contributed to successfully translating the recombinant adeno-associated viral vector from the laboratory to the clinic. The active deployment of these analytical technologies for process and product cha... More

Predictive Low-Glucose Suspend Necessitates Less Carbohydrate Supplementation to Rescue Hypoglycemia: Need to Revisit Current Hypoglycemia Treatment Guidelines

Current guidelines recommend 15–20 g of carbohydrate (CHO) for treatment of mild to moderate hypoglycemia. However, these guidelines do not account for reduced insulin during suspensions with predictive low-glucose suspend (PLGS). We assessed insulin suspensions, hypoglycemic events, and CHO treatme...

Insulin Metrics: Need for Development of Consensus Standards for Reporting of Insulin Dosing Data

The advent of connected insulin pens will generate an avalanche of digital insulin data, especially in the context of prandial- and multiple daily injection-insulin regimens. There is a need for the diabetes community to develop standards for such data, analogous to what has been achieved using the ... More

Continuous Glucose Monitoring Time-in-Range and HbA1c Targets in Pregnant Women with Type 1 Diabetes

The CONCEPTT trial compared real-time Continuous Glucose Monitoring (RT-CGM) to capillary glucose monitoring in pregnant women with type 1 diabetes. We analyzed CGM and glycated hemoglobin (HbA1c) measures in first (n = 221), second (n = 197), and third (n = 172) trimesters, aiming to examine target... More


Protocol

Correlates of Continuous Glucose Monitoring Use Trajectories in Children and Adolescents with Type 1 Diabetes

The goal of this study was to characterize trajectories of continuous glucose monitoring (CGM) use in youth 5–12 weeks after starting CGM and examine what factors differentiate between the trajectory groups. Parent–youth dyads completed assessments before starting CGM. Days of CGM use between weeks ... More

Sustainable Use of a Real-Time Continuous Glucose Monitoring System from 2018 to 2020

We aimed to describe patterns of continuous glucose monitoring (CGM) system use and glycemic outcomes from 2018 to 2020 in a large real-world cohort by analyzing anonymized data from US-based CGM users who transitioned from the G5 to the G6 System (Dexcom) in 2018. The main end points were persisten... More

School Nurse Perspectives on Do-It-Yourself Automated Pancreas Systems in the School Setting

Do-it-yourself (DIY) artificial pancreas systems (APSs) are gaining popularity among children with type 1 diabetes. Little is known about how school systems provide care for children who use DIY APSs, and available guidance for schools is limited. This study explored school staff perspectives on DIY... More


Protocol

Prevalence of SARS-CoV-2 Antibodies in Children and Adults with Type 1 Diabetes

Objective: As diabetes is a risk factor for severe symptoms, hospitalization, and death with COVID-19 disease, we aimed to assess the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in children and adults with and without type 1 diabetes in Colorado during 2020....

Continuous Glucose Monitoring and Glycemic Control in Young Adults with Type 1 Diabetes: Benefit for Even the Simplest Insulin Administration Methods

The impact of continuous glucose monitoring (CGM) on glycemic control in young adults with type 1 diabetes (T1D) is controversial. Data from 888 young adults with T1D were reviewed (ages 18–30 years, 52% female, glycated hemoglobin [HbA1c] 8.1% ± 1.5%). Prescription of CGM was recorded for 54% of yo... More

Locus-Specific Genomic DNA Purification Using the CRISPR System: Methods and Applications

A multitude of molecular interactions with chromatin governs various chromosomal functions in cells. Insights into the molecular compositions at specific genomic regions are pivotal to deepen our understanding of regulatory mechanisms and the pathogenesis of disorders caused by the abnormal regulati...
