Derivation And Validation Of A General Predictive Model For Long Term Risks For Mortality And Invasive Cardiovascular Interventions In Congenital Heart Disease, David A. Danford Dec 2021

Derivation And Validation Of A General Predictive Model For Long Term Risks For Mortality And Invasive Cardiovascular Interventions In Congenital Heart Disease, David A. Danford

Capstone Experience

Introduction. Accurate assessment of prognosis is a key driver of clinical decision making in congenital heart disease (CHD), but is complicated because CHD represents such a diverse collection of conditions. The aim of this investigation is to derive, validate, and calibrate multivariable predictive models for time to surgical or catheter-mediated intervention (INT) in CHD and for time to death in CHD. Methods. 4108 unique subjects were prospectively and consecutively enrolled, and randomized to derivation and validation cohorts. Total follow up was 26,578 patient-years, with 102 deaths and 868 INTs. Accelerated failure time multivariable predictive models for the outcomes, based on …


Glycemic Variability In Patients With Stage Ii-Iii Colon Cancer, Natalie Mandolfo Dec 2020

Glycemic Variability In Patients With Stage Ii-Iii Colon Cancer, Natalie Mandolfo

Theses & Dissertations

Patients with cancer experience metabolic changes such as hypoglycemia, hyperglycemia, and glycemic variability; collectively termed malglycemia. Glycemic variability, defined as fluctuations in glucose, is a marker of metabolic instability. Higher glycemic variability is associated with adverse health outcomes in the general population and in those with diabetes. Little is known about glycemic variability in patients with cancer, especially those with solid tumor malignancies. Glycemic variability is associated with increased infection, shorter periods of remission, and higher mortality in patients with hematological cancer. This body of work describes the concept and measurement of glycemic variability to assess glycemic control in patients …


Surgical Care Perspectives: Exploring Barriers And Facilitators To Surgery In Rural Nebraska, Sarah Stanislav May 2020

Surgical Care Perspectives: Exploring Barriers And Facilitators To Surgery In Rural Nebraska, Sarah Stanislav

Capstone Experience

Background: Minimally invasive surgery (MIS) is associated with less pain, faster recovery, and lower complication rates. Despite being the standard of care, it remains underutilized in rural Nebraska. Surgeon shortages and limited studies describing patient and provider factors influencing treatment gaps contribute to unnecessary complications and healthcare expenditure. Our study aimed to understand rural surgical care barriers and facilitators encountered by patients, providers, and stakeholders in Nebraska. Methods: This exploratory mixed methods study involved 17 semi-structured interviews using a snowball sampling of eligible participants affiliated with an MIS Advisory Committee. Two coders analyzed data using NVivo12. A follow-up review of …
