2D fetal echocardiography (ECHO) can be used for monitoring heart development in utero. This study’s purpose is to empirically model normal fetal heart growth and function changes during development by ECHO and compare these to fetuses diagnosed with and without cardiomyopathy with diabetic mothers. There are existing mathematical models describing fetal heart development but they warrant revalidation and adjustment. 377 normal fetuses with healthy mothers, 98 normal fetuses with diabetic mothers, and 37 fetuses with cardiomyopathy and diabetic mothers had their cardiac structural dimensions, cardiothoracic ratio, valve flow velocities, and heart rates measured by fetal ECHO in a retrospective chart review. Cardiac features were fitted to linear functions, with respect to gestational age, femur length, head circumference, and biparietal diameter and z-scores were created to model normal fetal growth for all parameters. These z-scores were used to assess what metrics had no difference in means between the normal fetuses of both healthy and diabetic mothers, but differed from those diagnosed with cardiomyopathy. It was found that functional metrics like mitral and tricuspid E wave and pulmonary velocity could be important predictors for cardiomyopathy when fitted by gestational age, femur length, head circumference, and biparietal diameter. Additionally, aortic and tricuspid annulus diameters when fitted to estimated gestational age showed potential to be predictors for fetal cardiomyopathy. While the metrics overlapped over their full range, combining them together may have the potential for predicting cardiomyopathy in utero. Future directions of this study will explore creating a classifier model that can predict cardiomyopathy using the metrics assessed in this study.

Participatory Budgeting (PB) can create changes within individuals and between them and their community. PB processes allow people to determine how to spend a portion of a particular budget (in the case of School PB, a portion of the school budget). These processes help address the underrepresentation of youth in the realm of civics.

I spent time with the steering committee and teacher coordinator of school PB in Carson Junior High to explore the impact of school PB on students’ knowledge, skills, attitudes and practices in relation to civic engagement. In the study I used quantitative and qualitative components. The participants were unique in that they all had prior experience in civic engagement programs in Carson Junior High that were organized by the teacher coordinator of school PB.

The main findings suggest that the participants reported a significant amount of learning in civic knowledge. In comparison, their overall perceived growth in attitudes, practices and skills were much lower. School PB helped the participants in the steering committee to grow in different ways than their other civic engagement programs by providing them with knowledge about budgets, their school’s mechanisms and other students within their school. They also became more familiar with the democratic process of voting and more comfortable with public speaking and presenting.

Recommendations for future research on this process include compiling quantitative and qualitative data from a larger sample consisting of students who had prior civic engagement experience and students who didn’t, and students with different ethnicities from different grades. Another recommendation for future research is to conduct a longitudinal study following school PB participants to high school and beyond to explore long-term impacts.
