MedicalResearch.com: What is the background for this study? What are the main findings?
Dr. Sorli: GLP-1 receptor agonists (GLP-1 RAs) have been found to be useful in the treatment of Type 2 diabetes with potent effects on blood glucose lowering while minimizing the risk of hypoglycemia and weight gain often seen with other classes of hypoglycemic agents.
Semaglutide is a novel GLP-1RA that is currently in clinical development. The molecule shares 94% amino acid homology with native GLP-1 and has a half-life of approximately one week allowing for once weekly dosing.
SUSTAIN 1 was designed to demonstrate superiority of semaglutide 0.5 mg and 1.0 mg once weekly over placebo in lowering HbA1c after 30 weeks of treatment. Additional secondary endpoints included weight loss versus placebo, percent of patients achieving HbA1c goals, percent of patients achieving 5% and 10% weight loss, and safety and tolerability.

Medical Research: What is the background for this study?
Dr. Correll: Antipsychotics have been used increasingly for psychotic, but also for many non-psychotic conditions, including for disorders and conditions for which they have not received regulatory approval. Moreover, antipsychotics have been associated with weight gain and abnormalities in blood fat and blood glucose levels. Although data in youth have been less available than in children and adolescents, youth appear to be more sensitive to the cardiometabolic adverse effects of antipsychotics than adults in whom significant weight gain might have already occurred due to long-term prior antipsychotic treatment. Nevertheless, type 2 diabetes, which is related to weight gain, overweight and obesity, seemed to be more common in adults than youth, likely due to the fact that it takes a long time for the body to develop diabetes. Recently, several individual epidemiologic or database studies with sufficient long-term follow-up durations suggested that the type 2 diabetes risk was higher in youth exposed to antipsychotics than healthy control youth and, possibly, even compared to psychiatrically ill patients treated with non-antipsychotic medications. However, a meta-analytic pooling of all available data has not been available to estimate the absolute and relative risk of type 2 diabetes in youth receiving antipsychotic treatment.
Medical Research: What are the main findings?
Dr. Correll: The main findings of the study that meta-analyzed data from 13 studies with 185,105 youth exposed to antipsychotics (average age 14.1 and 59.5 percent male) are that the absolute rates of type 2 diabetes are fortunately still relatively low, i.e. a cumulative type 2 diabetes risk of 5.7/1,000 patients and an exposure adjusted incidence rate of 3.1/1,000 patient-years. Nevertheless, the cumulative risk of

Medical Research: What is the background for this study? What are the main findings?
Dr. Zhang: Potatoes are the third most commonly consumed food crop in the world. In the United States, about 35% of women of reproductive age consume potatoes daily, accounting for 8% of daily total energy intake. Gestational diabetes mellitus (GDM) is a common complication of pregnancy characterized by glucose intolerance with onset or first recognition during pregnancy.

Medical Research: What is the background for this study?
Dr. Rowan: Clinicians are interested in screening during early pregnancy to identify women with previously unrecognised diabetes, as these women have increased risks of adverse pregnancy outcomes. HbA1c is a simple and reproducible measure of glucose elevations, but its usefulness as an early pregnancy screening test is not clear. The aim of this study was to examine whether pregnant women with an HbA1c of 41-49mmol/mol (5.9-6.6%) are a high risk subgroup and whether treating these women from early pregnancy improves outcomes compared with identifying them during routine screening for gestational diabetes (GDM) from 24 weeks’ gestation.
This observational study compared women referred to the diabetes clinic <24 weeks’ who had an early pregnancy
