Automation of Volumetric Analysis of Adiposity in Canines
Roughly 30-40% of all dogs and cats that are seen by a veterinarian can be classified as obese. Despite this, veterinary practices still utilize a 5 point or 9 point subjective classification system when classifying patients as obese, which can provide difficult when providing accurate nutritional consults to veterinary clients aiming to decrease their pet’s weight. Further, the obesity itself can lead to worsening of comorbid conditions. Thus, an automation of the process of assessing adiposity through CT scan was attempted, looking specifically at the thoracic region of the animal. First, the issues with the current BCS system were highlighted through the manual analysis of thoracic body fat in comparison to assigned BCS scores, with a focus on percent adiposity. Next, this process will be automated to analyze the adiposity of the thoracic region so it does not need to be done by hand for CT scans. To accommodate the average practitioner, this method will be applied en masse to radiographs through the comparison of animals who received radiographs and CT scans on the same day, and mathematically correlated to allow for x-ray utility for this tool. Finally, this will be applied to a variety of diseases to assess if there is a threshold adiposity level at which animals are at risk for a worsened prognosis.

Effects of Pain Management Clinical Decision Support in an Inpatient Setting for Patients Experiencing Abdominal Pain
Disorganization of pain-management-related information in an EMR may limit clinicians’ ability to consider clinical factors comprehensively. A clinical decision support (CDS) system for pain management was developed and deployed at University of Missouri Healthcare. CDS effects were examined for inpatients with diagnoses of diverticulitis, pancreatitis, and abdominal pain. Statistically significant differences were found in the average NRS-11 self-reported pain scores with a mean reduction of 0.7, and number of pain related medications prescribed, with a mean reduction of 1.2 pain medication orders per day. No statistical correlation was found between the use of the CDS and prescription of different classes of pain medications at discharge, nor with the use of naloxone for reversing overdose. Nurses were the primary user of the system, with 79.3% of all CDS views. Patients may benefit with overall reduced pain scores and improved medication management with the use of this CDS.

Use of Powerful Tools for Meaningful Conclusions from Sparse Data
At any given time, over 10 million women are pregnant or lactating in the United States, about 80% of these pregnancies result in a normal pregnancy and life birth. The remaining are associated with a wide range of pregnancy related diseases, an even lower percent of patients present with complications not related to the pregnancy itself. The size of the data is at first glance exciting for the informatics researcher however, the low incidence of positive cases of each type of disease results in sparse data difficult to analyze resulting in less than ideal models for data mining and knowledge extraction. During the seminar I will illustrate the relevance of pregnancy related research focusing then on the demonstration of how data manipulation, manual annotation, the use of publicly available tools make it possible to extract useful information and draw valid conclusions with well-known machine learning algorithms.

Using Social Network Analysis and Natural Language Processing to Describe Communication Practices of Interdisciplinary Teams in Primary Care
The Electronic Medical Record (EMR) serves different purposes including documentation of care and billing. One part of the EMR at the University of Missouri Hospital and Clinics is the Message Center. Many people, including healthcare providers, nurses, social workers, therapists, office staff, and nurse care managers (known as the interdisciplinary team, or IDT) work together to deliver healthcare.
This research examines how the Message Center is used in primary care by nurse care managers to document care coordination activities, including communication between patients, patient identified family or significant other, and the IDT. Care coordination activities, and the focus of those activities will be extracted and described. Social network analysis will be used to expose and map the communication between different users of message center. This research aims to describe communication practices across healthcare settings.

Seasonal Influenza Vaccine: Not easy shot to get
During the past nearly 50 years, antigenic variants of subtype H3N2 influenza A viruses have frequently emerged, causing significant public health challenges. The manner in which these variants emerge and their patterns of spread are not well understood. We identified 15 antigenic drift events with 16 antigenic variants during 1968–2016 by using a novel genomic sequence–based antigenicity inference method on ~40,000 H3N2 viruses. New antigenic variants were shown to emerge from certain locations in other continents rather than from Asia alone, and variants emerged year-round and took <2 months to spread across multiple continents. The uncertainty of the location of antigenic variant emergence and the rapidity of viral spread pose great challenges for influenza surveillance. Our findings suggest that a more robust H3N2 virus surveillance strategy, including sampling from unrepresented areas (e.g., tropical locations) and outside influenza seasons, would help identify the emergence of antigenic variants.
