Research Question: What are the qualitative insights and perspectives about the implementation of a mindfulness and yoga-based program from elementary youth and teachers?
Context: A mindfulness and yoga-based curriculum was implemented in 15 schools. The curriculum was taught to students during a physical education or dance class by instructors who were within each school and received training on the curriculum.
Sample Selection: Volunteer focus group elementary students who participated for one year and teachers who did not implement the program were qualitatively interviewed, by three trained University researchers.
Background: Glycemic index and glycemic load are used to facilitate glucose control among adults with type 2 diabetes, with a low glycemic index diet associated with improved glycemic control.
Objective: To examine long-term longitudinal associations between changes in glycemic index and glycemic load with glycemic and metabolic control among Latino adults with diabetes.
Design: Secondary data from intervention and comparison participants in the Latinos en Control trial (2006 to 2008) were analyzed.
Objective: Social influences play an important role in shaping adolescents' dietary and physical activity behaviors. We examined the role of perceived modeling and perceived social support from family and friends on diet and physical activity behaviors among overweight and obese adolescents participating in a weight management trial.
Methods: Six high schools were randomized to a school-nurse delivered behavioral weight management intervention or an information attention-control.
Background: Models are needed for implementing weight management interventions for adolescents through readily accessible venues. This study evaluated the feasibility and efficacy of a school nurse-delivered intervention in improving diet and activity and reducing body mass index (BMI) among overweight and obese adolescents.
Methods: Six high schools were randomized to either a 6-session school nurse-delivered counseling intervention utilizing cognitive-behavioral techniques or nurse contact with provision of information.
Objective: In preparation for a pilot study to evaluate the efficacy of a school nurse-delivered intervention, focus groups were conducted to gain insight into the perceptions of stakeholders regarding the design and implementation of the intervention.
Setting And Participants: Fifteen focus groups at participating schools. One hundred subjects, including overweight and obese high school students, parents, high school nurses, and staff.
Background: Lipids accumulate during the storage of red blood cells (RBCs), prime neutrophils (PMNs), and have been implicated in transfusion-related acute lung injury (TRALI). These lipids are composed of two classes: nonpolar lipids and lysophosphatidylcholines based on their retention time on separation by high-pressure liquid chromatography. Prestorage leukoreduction significantly decreases white blood cell and platelet contamination of RBCs; therefore, it is hypothesized that prestorage leukoreduction changes the classes of lipids that accumulate during storage, and these lipids prime PMNs and induce acute lung injury (ALI) as the second event in a two-event in vivo model.

Participants demonstrated significantly lower mean daytime blood glucose and a trend toward lower variability, suggesting a clinically relevant impact of reducing glycemic index.

Methods: Youths with type 1 diabetes (7.0 to 16.
A low-glycemic index (GI) diet may lower postprandial hyperglycemia and decrease the risk for postabsorptive hypoglycemia in people with type 1 diabetes. However, insufficient evidence exists on the efficacy of a low-GI diet to support practice recommendations. The goal of this study was to examine the blood glucose response to and the macronutrient composition of low-GI meals vs usual meals consumed ad libitum at home in children with type 1 diabetes.

Research Design And Methods: A total of 20 youths on basal-bolus regimens consumed macronutrient-matched HGI and LGI meals 1 day each in a controlled setting in varying order following consumption of a standardized evening meal. Medtronic MiniMed Continuous Glucose Monitoring Systems were used to assess blood glucose (BG) profiles.
Purpose: The purpose of this study was to explore the perceptions of healthy eating by youth with diabetes as well as facilitators of and barriers to healthy eating behavior.
Methods: One hundred forty youth aged 7 to 16 years with diabetes participated in 18 focus groups. Sample race/ethnicity was 71% white, 18% African American, 6% Hispanic, and 5% other; 69% of the participants were female.

Objective: To determine the acceptability of lower glycemic index (GI) foods served at diabetes camp.
Design: Crossover design of standard and lower GI menus.
Setting: Three consecutive 5-day diabetes camp sessions.
