Technical considerations of cardiac computed tomography in children.

Cardiac computed tomography angiography (CTA) is a valuable tool in the assessment of congenital and acquired cardiac disease in children. The goal of cardiac CTA is to produce images that are free of motion and provide sufficient characterization of the anatomy in question. Given the complexity of pediatric patient characteristics, including patient size, heart rate, breath-holding capability, and variant anatomy, cardiac CTA technique must be individualized to the patient as well as the indication to answer the clinical question while also minimizing radiation exposure.

A Scale-Out Study of an Evidence-Based Family Meals Program Delivered in the Head Start Setting: Results, Challenges, and Opportunities.

There is need to identify evidence-based early childhood obesity prevention programs that are feasible and demonstrate cost-effectiveness for a broader health impact. This scale-out study leveraged community-engaged principles to compare the feasibility and cost-effectiveness of three delivery modes of a childhood obesity prevention family meals program (Simple Suppers) that demonstrated positive impacts on child and caregiver diet/nutritional health-related outcomes in a previous experimental trial tested among elementary-aged children. This three-arm (in-person, online, hybrid) pre-(T0) and post-(T1)-test study included families recruited from Head Start.

Achieving 3-D Structural Uniformity in Cellulose Gel Beads via Salt Screening.

Cellulose microgel beads fabricated using the dropping technique suffer from structural irregularity and mechanical variability. This limits their translation to biomedical applications that are sensitive to variations in material properties. Ionic salts are often uncontrolled by-products of this technique, despite the known effects of ionic salts on cellulose assembly.

Evaluating bias in electronic health record data: using agent-based models to examine whether geographic disparities in community-acquired Methicillin-resistant Staphylococcus aureus are due to differential healthcare-seeking behaviors.

Electronic health records (EHR) are increasingly used in public health research. However, biases may exist when using EHR due to whether someone is captured in the data. Assessing the impact of bias in generating disparities identified with EHR data is difficult because information about healthcare-seeking behaviors is not included in the record.

Maternal resistance exercise increases infant energy expenditure.

Maternal obesity decreases infant energy expenditure, subsequently predisposing infants to greater adiposity and weight gain. Conversely, some findings suggest that maternal exercise may increase infant energy expenditure; however, the impact of maternal exercise mode (i.e.
