Elizabeth M. Cespedes Feliciano, ScD, SM, is a Research Scientist II at the Kaiser Permanente Northern California Division of Research. Her research focuses on identifying, understanding, and intervening on modifiable risk factors for obesity and cancer-related metabolic diseases. She holds a Bachelor of Arts from Brown University, a Masters in Social and Behavioral Sciences from the Harvard T.H. Chan School of Public Health, and a doctorate in Epidemiology and Nutrition, also from Harvard University. Dr. Cespedes Feliciano’s research focuses on two main content areas: (1) cancer survivorship, specifically assessing body composition and cancer outcomes including treatment-related toxicity, surgical complications, recurrence, and survival, and (2) cardiometabolic health, specifically assessing the role of sleep and diet.

Studies

Informatics approaches to assessing patient frailty in surgical care

Patient frailty increases the risk for surgical complications, which are common, costly, and deadly, especially for older Americans. To improve surgical care for older adults, we will investigate whether electronic measures of frailty can help reduce complications by identifying which patients are likely to be readmitted to the hospital or die soon after surgery.

Body Composition and Breast Cancer Survival: Immune and Metabolic Biomarkers in Breast Tumors

We previously found that one third of nonmetastatic breast cancer patients had sarcopenia (age-related loss of muscle tissue) at the time of their diagnosis and that having sarcopenia and obesity was associated with an 89% increased risk of death. This study will use 1,400 archived clinical tumor tissues from stage II-III breast cancer patients for whom we have data on body composition, metabolic syndrome, weight history, cancer therapy, and long-term follow-up for breast cancer outcomes. We will classify breast cancer molecular subtypes, measure gene expression levels in immune and metabolic pathways potentially influenced by body composition and the metabolic syndrome, and examine whether alterations in the breast cancer tumor microenvironment mediate the association of body composition and breast cancer survival.

D3-creatine dilution to assess skeletal muscle mass in colon cancer patients

Among colon cancer patients participating in a resistance training intervention during chemotherapy, this study will examine whether a new method to evaluate skeletal muscle mass (d3-creatine dilution) is associated with the key cancer outcomes of strength and physical function, chemotherapy toxicity, inflammation, cardiometabolic risk factors and markers of tumor recurrence.

Pediatric obstructive sleep apnea: predictive modeling to streamline care

To prioritize pediatric attended polysomnography and treatment for children most in need while reducing the unnecessary use of overnight sleep studies, we propose to build and rigorously evaluate a clinical risk prediction model. We will combine data from pediatric sleep questionnaires with other risk factors derived from the electronic medical record to predict obstructive sleep apnea severity among pediatric sleep patients and evaluate our model's performance in an independent sample.

Healthful dietary patterns, intermediate biomarkers and long-term breast cancer prognosis

To strengthen the dietary guidelines for breast cancer survivors, we examine whether at-diagnosis concordance with healthful dietary patterns is associated with recurrence or breast cancer death, or with prognostic biomarkers (i.e., body composition, inflammation or metabolic syndrome). Secondarily, we will examine whether improving diet quality (or maintaining high diet quality) after diagnosis reduces risk of recurrence or breast cancer death.

Beyond Body Mass Index: Bringing Body Composition into Oncology Practice

This project consists of development of electronic tools to rapidly assess body composition in colorectal cancer and breast cancer patients and present this information to clinicians. It leverages Kaiser Permanente Northern California’s electronic medical records and repository of CT images, including 6,000 images from colorectal cancer and breast cancer patients that were previously manually analyzed for body composition. This project has three major aims: validate software to automatically assess body composition from clinically-acquired imaging (Aim 1); improve the predictive performance of established colorectal cancer risk prediction models through the addition of body composition variables (Aim 2); and develop a prototype of an electronic decision support tool that presents personalized patient risk information to clinicians in an understandable and actionable format (Aim 3).
