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.
Through the use of Arizona State University’s Founders Lab, our group of four Barrett, the Honors College Students completed a research thesis regarding the interest of college students in a sleep light technology product. The National Aeronautics and Space Administration (NASA) pioneered a sleep light technology with the ability to regulate melatonin production and circadian rhythm, resulting in an improvement of sleep quality. The technology was originally invented for astronauts to improve their sleep while in space on a spacecraft. Utilizing this technology, our group performed extensive market research with the intention of determining if college students would be interested in purchasing a consumer product incorporating the sleep light technology. We created a brand called Rhythm Illumination and began by building a website and brand guide. Next, we utilized Google Forms to generate responses to a variety of questions regarding current sleep habits, current sleep problems, and whether or not there was interest in a product like this. After determining that college students have room for sleep quality improvement and there is interest in this kind of product, we worked towards our goal of gaining traction for the product. We decided to utilize both Google Analytics results and a Zoom event’s attendance as proof of interest in our product. Google Analytics revealed over one hundred unique users on our Rhythm Illumination website. We also had eleven event attendees. Between these two tools, our team was able to conclude that there is interest among college students for a consumer product utilizing NASA’s sleep light technology
