Keynote: Medicaid beneficiaries who continue to use the ED: A focus on the Illinois medical home network
Time : 09:00-09:35
Biography:
Yanina Purim-Shem-Tov graduated from the University of Chicago, Pritzker School of Medicine in 1998; completed emergency medicine residency at Cook County Hospital, in 2002, and began full-time employment at Rush University Medical Center (RUMC). She has completed Master’s Program in Clinical Research in 2006. Her Master Thesis focused on patients with chest pain, whom were admitted to the Emergency Department Observation Unit, a published manuscript. Presently, she is a Senior Medical Director of the Department of Emergency Medicine at RUMC. She is an NIH-supported researcher, clinician, and an educator. I have numerous publications in the areas of Emergency Medicine.
Abstract:
Objectives: Frequent, non-urgent emergency department use continues to plague the American healthcare system through ineffective disease management and unnecessary costs. In 2012, the Illinois Medical Home Network (MHN) was implemented, in part, to reduce an overreliance on already stressed emergency departments through better care coordination and access to primary care. The purpose of this study is to characterize MHN patients and compare them to non-MHN patients for a preliminary understanding of MHN patients who visit the emergency department. Variables of interest include: 1) frequency of emergency department use during the previous twelve months; 2) demographic characteristics; 3) acuity; 4) disposition; and 5) comorbidities. rnrnMethods: We performed a retrospective data analysis of all emergency department visits at a large, urban academic medical center in 2013. Binary logistic regression analyses and analysis of variance were used to analyze data. rnrnResults: MHN patients visited the emergency department more often than non-MHN patients. MHN patients were more likely to be African American, Hispanic/Latino, female, and minors when compared with non-MHN patients. Greater proportions of MHN patients visiting the emergency department had asthma diagnoses. MHN patients possessed higher acuity but were more likely to be discharged from the emergency department compared with non-MHN patients. rnrnConclusions: This research may assist with developing and evaluating intervention strategies targeting the reduction of health disparities through decreased use of emergency department services in these traditionally underserved populations.rn

Jara Pérez-Jiménez
Institute of Food Science, Technology and Nutrition, Spain
Keynote: Antioxidant capacity of the Spanish Mediterranean diet: A whole approach including macromolecular antioxidants
Time : 09:35-10:10
Biography:
Jara Pérez-Jiménez completed her PhD in 2007. She has worked in several research centers and universities in Spain and France focused on the study of food bioactive compounds, in particular polyphenols, using a multidisciplinary approach. These research activities have given place to more than 45 papers in international scientific journals (>1,600 citations, h-index: 21), as well as to more than 50 works presented in scientific meetings and invited conferences in different universities. She is a member of the Editorial Board of Food Research International, as well as Academic Editor of PeerJ.
Abstract:
Epidemiological and clinical studies show that diets with a high antioxidant capacity (AC) reduce the overall risk of cardiovascular diseases, neurodegenerative diseases or certain kinds of cancer. However, these studies focus exclusively on low molecular weight or soluble antioxidants (vitamins C and E, phenolic compounds and carotenoids), ignoring macromolecular antioxidants. These are polymeric phenolic compounds or polyphenols and carotenoids linked to plant food macromolecules that yield bio-available metabolites by the action of the micro-biota, with beneficial effects either local and/or systemic after absorption. The aim of this work was to estimate the AC of a whole diet -the Spanish Mediterranean Diet (MD) considering for the first time both soluble and macromolecular antioxidants. Plant food and beverage consumptions in the Spanish diet were based on national 2013 data obtained from 12,000 daily household spending questionnaires. From this, 54 food and beverages were selected and soluble and macromolecular antioxidants were obtained. Antioxidant capacity was measured in both fractions by two complementary methods and expressed in Trolox equivalents- the standard units for AC. From these data, it was obtained that total AC of the Spanish MD was 8,000 µmol Trolox/p/day with the 61% provided by macromolecular antioxidants. Therefore, the first determination of Antioxidant Capacity in a diet (Spanish MD) including macromolecular antioxidants shows that these commonly ignored compounds are major contributors to total AC. Including macromolecular antioxidants in mechanistic, intervention and observational studies on dietary antioxidants may contribute to a better understanding of the role of antioxidants in nutrition and health.rnrn
