Etiological Approach to Characterization of Diabetes Type: The SEARCH for Diabetes in Youth Study

OBJECTIVE To describe an etiologic approach to classification of diabetes types in youth based on the 1997 American Diabetes Association (ADA) framework, using data from the SEARCH for Diabetes in Youth Study

Insulin Regimens and Clinical Outcomes in a Type 1 Diabetes Cohort: The SEARCH for Diabetes in Youth study

OBJECTIVE To examine the patterns and associations of insulin regimens and change in regimens with clinical outcomes in a diverse population of children with recently diagnosed type 1 diabetes

Adherence to Guidelines for Youths With Diabetes Mellitus

To describe demographic and clinical characteristics associated with self-reported receipt of tests and measurements recommended by the American Diabetes Association (ADA) for children and youths with diabetes

Development, validation and use of an insulin sensitivity score in youths with diabetes: the SEARCH for Diabetes in Youth study

The ability to measure insulin sensitivity across the phenotypic spectrum of diabetes may contribute to a more accurate characterisation of diabetes type. Our goal was to develop and validate an insulin sensitivity (IS) score using the euglycaemic–hyperinsulinaemic clamp in a subset (n=85) of 12– to 19-year-old youths with diabetes participating in the SEARCH study in Colorado, USA

Screen for Genetic Modifiers of stbm Reveals that Photoreceptor Fate and Rotation Can Be Genetically Uncoupled in the Drosophila Eye

BACKGROUND: Polarity of the Drosophila compound eye arises primarily as a consequence of two events that are tightly linked in time and space: fate specification of two photoreceptor cells, R3 and R4, and the subsequent directional movement of the unit eyes of the compound eye, or ommatidia. While it is thought that these fates dictate the direction of ommatidial rotation, the phenotype of mutants in the genes that set up this polarity led to the hypothesis that these two events could be uncoupled. METHODOLOGY/PRINCIPAL FINDINGS: To definitively demonstrate these events are genetically separable, we conducted a dominant modifier screen to determine if genes, when misexpressed, could selectively enhance subclasses of mutant ommatidia in which the direction of rotation does not follow the R3/R4 cell fates, yet not affect the number of ommatidia in which rotation follows the R3/R4 cell fates. We identified a subset of P element lines that exhibit this selective enhancement. We also identified lines that behave in the opposite manner: They enhance the number of ommatidia that rotate in the right direction, but do not alter the number of ommatidia that rotate incorrectly with respect to the R3/R4 fates. CONCLUSIONS/SIGNIFICANCE: These results indicate that fate and direction of rotation can be genetically separated, and that there are genes that act between R3/R4 fate specification and direction of ommatidial rotation. These data affirm what has been a long-standing assumption about the genetic control of ommatidial polarity

Correlates of Dietary Intake in Youth with Diabetes: Results from the SEARCH for Diabetes in Youth Study

AbstractObjectiveTo explore demographic, socioeconomic, diabetes-related, and behavioral correlates of dietary intake of dairy, fruit, vegetables, sweetened soda, fiber, calcium, and saturated fat in youth with diabetes.MethodsCross-sectional study of youth 10-22 years old with type 1 (T1DM, n=2,176) and type 2 diabetes (T2DM, n=365). Association of dietary intake, demographics, socioeconomic status, behavioral, and diabetes-related measures was explored with quantile regression.ResultsT1DM males had lower consumption of vegetables, fruit, and fiber, and higher consumption of soda and saturated fat than females (P < .01). African Americans had lower dairy and higher soda intake than non-Hispanic T1DM whites (P < .01). Soda consumption was higher in older T2DM youth than in younger participants (P < .01). Lifestyle and physical activity patterns were also significantly associated with dietary intake.Conclusions and ImplicationsIdentified demographic and behavioral correlates may help dietitians to focus on groups of youth with diabetes who have lower adherence to a healthful diet. Diet counseling groups may be tailored according to these major determinants
