Recent studies have shown that an artificial-pancreas system can improve glucose control and reduce nocturnal hypoglycemia. However, it is not known whether such results be replicated in settings outside the hospital.In this multicenter, multinational, randomized, crossover trial, we assessed short-term safety efficacy of artificial pancreas for levels patients (10 to 18 years age) with type 1 diabetes at a camp. In two consecutive overnight sessions, randomly assigned 56 receive treatment...

The 65-kD isoform of glutamic acid decarboxylase (GAD65) is a major autoantigen in type 1 diabetes. We hypothesized that alum-formulated GAD65 (GAD-alum) can preserve beta-cell function patients with recent-onset diabetes.We studied 334 patients, 10 to 20 years age, diabetes, fasting C-peptide levels more than 0.3 ng per milliliter (0.1 nmol liter), and detectable serum autoantibodies. Within 3 months after diagnosis, were randomly assigned receive one three study treatments: four doses...

Abstract The significant and growing global prevalence of diabetes continues to challenge people with (PwD), healthcare providers, payers. While maintaining near-normal glucose levels has been shown prevent or delay the progression long-term complications diabetes, a proportion PwD are not attaining their glycemic goals. During past 6 years, we have seen tremendous advances in automated insulin delivery (AID) technologies. Numerous randomized controlled trials real-world studies that use AID...

OBJECTIVE—To investigate thyroid autoimmunity in a very large nationwide cohort of children and adolescents with type 1 diabetes. RESEARCH DESIGN AND METHODS—Data were analyzed from 17,749 patients diabetes aged 0.1–20 years who treated 118 pediatric centers Germany Austria. Antibodies to thyroglobulin (anti-TG) thyroperoxidase (anti-TPO) measured documented at least once 7,097 patients. A total 49.5% these boys, the mean age was 12.4 (range 0.3–20.0 years), duration 4.5 0.0–19.5 years)....

OBJECTIVE—The aim of this data analysis was to ascertain the type and prevalence rate as well age sex distribution cardiovascular risk factors in 1 diabetic patients up 26 years age. RESEARCH DESIGN AND METHODS—Cardiovascular such obesity, hypertension, dyslipidemia, poor glycemic control, smoking were analyzed 27,358 who divided into three groups (prepubertal, pubertal, adult) using specifically designed diabetes software for prospective disease documentation. RESULTS—More than half per...

RESEARCH DESIGN AND METHODS—In 324 Caucasian women GDM, BMI before pregnancy, maternal glycemic values, measurements fetal abdominal circumference were recorded. The weight height infants measured at birth follow-up 5.4 years (range 2.5–8.5). In addition, somatic data routine examinations 6,...

We evaluated the effect of MD-Logic system on overnight glycemic control at patients' homes.Twenty-four patients (aged 12-43 years; average A1c 7.5 ± 0.8%, 58.1 8.4 mmol/mol) were randomly assigned to participate in two crossover periods, each including 6 weeks consecutive nights: one under closed loop and second sensor-augmented pump (SAP) therapy homes real-life conditions. The primary end point was time spent with sensor glucose levels below 70 mg/dL (3.9 mmol/L) overnight.Closed-loop...

Severe hypoglycemic episodes are a barrier for achieving optimal glycemic control. Sensor-augmented pump (SAP) therapy with insulin in combination novel mechanism of automatic shutoff (low glucose suspend [LGS]) can be used to prevent and reduce hypoglycemia. In prospective study, we investigated the effect LGS algorithm on frequency hypoglycemia children adolescents type 1 diabetes under real-life conditions.Twenty-one patients (10.8±3.8 years old, duration 5.9±3.0 years, 3.7±1.7 glycated...

A sensor-augmented insulin pump (SAP) using the MiniMed® 640G system with SmartGuard™ technology allows an automatic stop of delivery based on prediction low glucose levels. Since pediatric patients are particularly prone to hypoglycemia, this device may offer additional protection beyond conventional therapy.This prospective, multicenter user evaluation assessed 6 weeks SAP SmartGuard (threshold setting for hypoglycemia: 70 mg/dL) compared a preceding period 2 only. The primary outcome was...
