Postprandial hyperglycemia due to paradoxical hyperglucagonemia is a major challenge of diabetes treatment despite the use of the artificial pancreas. We postulated that adjunctive therapy with pramlintide or exenatide would attenuate hyperglycemia in the postprandial phase through glucagon suppression, thereby optimizing the functioning of the closed-loop (CL) system. Subjects with type 1 diabetes (T1DM) on insulin pump therapy were recruited to participate in a 27-hour hospitalized admission on 3 occasions (2-4 weeks apart) and placed on the insulin delivery via CL system in random order to receive (1) insulin alone (control), (2) exenatide 2.

Background: Along with the rise in obesity, cardiovascular disease (CVD) has become the major cause of death in developed countries. Although overt coronary heart disease rarely manifests during childhood, atherosclerosis can begin by the second decade of life. Therefore, identifying reliable risk markers of early vascular disease in childhood could be important.

Hypoglycemia is a common complication of insulin treatment in type 1 diabetes mellitus and can occur in any patient with diabetes when glucose consumption exceeds supply. Many studies have been done to elucidate those factors that predict severe hypoglycemia: younger age, longer duration of diabetes, lower HgbA1c, higher insulin dose, lower Body Mass Index, male gender, Caucasian race, underinsurance or low socioeconomic status, and the presence of psychiatric disorders. Hypoglycemia can affect patients' relationships, occupation, and daily activities such as driving.

Objective: To assess the risk factors for developing hyperglycemia and diabetes mellitus (DM) in children with pancreatitis.

Study Design: Patients (from infants to age 21 years) hospitalized with acute pancreatitis (AP), acute recurrent pancreatitis (ARP), and chronic pancreatitis were studied retrospectively. Subjects with known DM or cystic fibrosis before presentation with pancreatitis were excluded.

The objective of this study was to evaluate the impact of short stature on generic health-related quality of life (HRQOL) and cognitive functioning in pediatric patients. Eighty-nine youth, 48 who were initially seen with short stature (SS group) and 41 with a history of short stature being treated with growth hormone (GHT group) and one of their legal guardians participated in the study. HRQOL and cognitive functioning were assessed using the PedsQL™ 4.

Objective: We hypothesized that insulin detemir mixed with aspart had equivalent effects on blood glucose as if being given as separate injections in pediatric type 1 diabetes patients.

Research Design And Methods: Fourteen children with type 1 diabetes were randomly assigned to either Study A (mixed insulins) or Study B (separate insulins) for the first 10 days and crossed over for the last 10 days. Each subject underwent continuous glucose monitoring on the last 72 h of each study.

Objective: The goal was to assess emergency preparedness among families caring for children with type 1 diabetes mellitus.

Methods: A total of 115 English-speaking families caring for children with type 1 diabetes mellitus who were attending the diabetes clinic at Texas Children's Hospital agreed to a questionnaire study designed to ascertain their level of preparedness for a disaster or emergency. The study was conducted from June through September 2008 and ended just before Hurricane Ike made landfall.
