Mealtime Insulin BOLUS Score More Strongly Predicts HbA Than the Self-Care Inventory in Youth With Type 1 Diabetes.

Background: To meet their glycated hemoglobin (HbA) goals, youth with type 1 diabetes (T1D) need to engage with their daily T1D treatment. The mealtime insulin Bolus score (BOLUS) is an objective measure of youth's T1D engagement which we have previously shown to be superior to other objective engagement measures in predicting youth's HbA. Here, to further assess the BOLUS score's validity, we compared the strengths of the associations between youth's HbA with their mean insulin BOLUS score and a valid, self-report measure of T1D engagement, the Self-Care Inventory (SCI).

International Guideline Adherence in Girls with Turner Syndrome: Multiple Subspecialty Clinics Versus Coordinated Multidisciplinary Clinic.

Objective: To evaluate the 2016 Cincinnati International Turner syndrome (TS) consensus guideline adherence within our pediatric tertiary referral center and determine if patients managed in our single-day, coordinated multidisciplinary clinic (MDC) format showed superior adherence rates when compared with those managed outside our MDC format.

Methods: We retrospectively reviewed the charts of patients with TS followed at our center from January 1, 2018, to April 30, 2020. The individual and overall adherence rates of 9 age-appropriate screening recommendations were evaluated along with rates of TS comorbidities within our cohort.

Accuracy of Three Commercial Home-Use Hemoglobin A1c Tests.

The COVID-19 pandemic and the rapid expansion of telemedicine have increased the need for accurate and reliable capillary hemoglobin A1c (HbA1c) testing. Nevertheless, validation studies of commercially available products suitable for home use have been in short supply. Three commercial home-use capillary blood sample HbA1c tests (Home Access, CoreMedica, and A1cNow+) were evaluated in 219 participants with type 1 or type 2 diabetes (4-80 years years of age, HbA1c 5.

Increased Prevalence of Beta-Cell Dysfunction despite Normal HbA1c in Youth and Young Adults with Turner Syndrome.

Introduction: Adult women with Turner syndrome (TS) have a high prevalence of diabetes and β-cell dysfunction that increases morbidity and mortality, but it is unknown if there is β-cell dysfunction present in youth with TS. This study aimed to determine the prevalence of β-cell dysfunction in youth with TS and the impact of traditional therapies on insulin sensitivity (SI) and insulin secretion.

Methods: Cross-sectional, observational study recruited 60 girls with TS and 60 healthy controls (HC) matched on pubertal status.

An Evaluation of Two Capillary Sample Collection Kits for Laboratory Measurement of HbA1c.

The COVID-19 pandemic has impacted the conduct of clinic visits. We conducted a study to evaluate two academic laboratories' fingerstick capillary blood collection kits suitable for home use for laboratory measurement of HbA1c. Four clinical sites recruited 240 participants (aged 4-80 years, HbA1c 5.

National Cooperative Growth Study: 25 Years of Growth Hormone Data, Insights, and Lessons for Future Registries.

Background: The National Cooperative Growth Study (NCGS) data are reviewed from 1985-2010 to report on final demographic, efficacy, and safety findings, and to illustrate the value of long-term, real-world follow-up to physicians and patients.

Methods: The NCGS was a multicenter, open-label, observational, postmarketing surveillance study of Genentech growth hormone (GH) products for the treatment of children with growth failure in North America.

Findings: Data from 65,205 patients representing 240,951 patient-years of experience were collected.

Employing a results-based algorithm to reduce laboratory utilization in ACTH stimulation testing.

Background: The High Dose Adrenocorticotropic Hormone (ACTH) Stimulation Test is the gold standard to diagnose adrenal insufficiency. Normal adrenal function is defined as a peak cortisol response to pharmacologic stimulation with cosyntropin of ≥18 μg/dL. Our practice was to obtain cortisol levels at 0, 30 and 60 min after cosyntropin administration.

Proceedings from the Turner Resource Network symposium: the crossroads of health care research and health care delivery.

Turner syndrome, a congenital condition that affects ∼1/2,500 births, results from absence or structural alteration of the second sex chromosome. There has been substantial effort by numerous clinical and genetic research groups to delineate the clinical, pathophysiological, cytogenetic, and molecular features of this multisystem condition. Questions about the molecular-genetic and biological basis of many of the clinical features remain unanswered, and health care providers and families seek improved care for affected individuals.

Use of aromatase inhibitors in children with short stature.

Estrogen has been shown to have an important role in skeletal maturation in both males and females. The use of aromatase inhibitors may provide a means to delay skeletal maturation and increase final height in children with short stature. These medications have been used primarily in women with breast carcinoma and also in children with autonomous estrogen production, such as patients with McCune-Albright Syndrome.
