A Time-Friendly, Feasible Measure of Nutrition Knowledge in Type 1 Diabetes: The Electronic Nutrition and Carbohydrate Counting Quiz (eNCQ).

Background: Greater knowledge about nutrition and carbohydrate counting are associated with improved glycemic control and quality of life in youth with type 1 diabetes (T1D). However, limited assessments of nutrition and carbohydrate knowledge have been developed, and existing measures can be time-consuming, overly broad, or not conducive to routine clinical use. To fill this gap, we developed and examined the feasibility of administering the electronic Nutrition and Carbohydrate Counting Quiz (eNCQ).

Sociodemographic Factors Associated With Changes in Successful Aging in Spain: A Follow-Up Study.

Objective: Successful aging (SA) refers to maintaining well-being in old age. Several definitions or models of SA exist (biomedical, psychosocial, and mixed). We examined the longitudinal association between various SA models and sociodemographic factors, and analyzed the patterns of change within these models.

Sedentary Behavior and Cardiometabolic Health Associations in Obese 11-13-Year Olds.

Background: Improved understanding of sedentary time's impact on cardiometabolic health can help prioritize intervention targets.

Objective: We investigated cross-sectional and longitudinal relations of reported screen time and objectively measured total percent of time spent sedentary with cardiometabolic health in obese youth.

Methods: Participants were 106 obese adolescents age 11-13 (N = 106, 51% girls, and 82% Hispanic) recruited from primary care clinics in southern California.

Modeling the allocation system: principles for robust design before restructuring.

The United Network for Organ Sharing is poised to resolve geographic disparity in liver transplantation and promote allocation based on medical urgency. At the time of writing, United Network for Organ Sharing is considering redistricting the organ procurement and transplantation network so that patient model for end-stage liver disease scores at transplant is more uniform across regions.We review the proposal with a systems-engineering focus and find that although the proposal is promising, it currently lacks evidence that it would perform effectively under realistic departures from its underlying data and assumptions.
