Robustness Of A Newly Proposed Risk Schema For Lymphatic Dissemination In Endometrioid Endometrial Cancer, Danielle M. Greer, Jessica J.F. Kram, Callie M. Cox Bauer, Scott A. Kamelle Jul 2019

Robustness Of A Newly Proposed Risk Schema For Lymphatic Dissemination In Endometrioid Endometrial Cancer, Danielle M. Greer, Jessica J.F. Kram, Callie M. Cox Bauer, Scott A. Kamelle

Aurora Ob/Gyn Faculty

Background: Surgical management for endometrioid endometrial cancer (EEC) includes complete lymph node dissection for all patients at risk of lymphatic dissemination. The standard risk schema, defined by Mayo Clinic, identifies low-risk patients as those with grade 1/2 EEC, myometrial invasion (MI) ≤ 50%, and tumor diameter (TD) ≤ 2 cm. We recently proposed (and published) a risk schema containing modified forms of grade, MI and TD that suggests a significant decrease in false-negative rate and need for lymphadenectomy in low-risk women.

Purpose: Evaluate robustness of our proposed schema for lymphatic dissemination risk stratification in a subsequent EEC patient cohort.

Segmental Distribution Of Hepatocellular Carcinoma Correlates With Microvascular Invasion In Liver Explants Undergoing Transplantation, Yasir Al-Azzawai, Eva Rouanet, Ryan J. Hendrix, Lidia Spaho, Hesham Malik, Deepika Devuni, Gyongyi Szabo, Graham Barnard

Gyongyi Szabo

Introduction: Microvascular invasion (MVI) in hepatocellular carcinoma (HCC) patients is a poor prognostic factor after liver transplantation and/or resection. Any correlation between MVI and segmental location of HCC has yet to be studied. Our aim is to evaluate the segmental location of HCC and any correlation with the presence of MVI, portal vein thrombosis (PVT) in explanted livers, and the recurrence of HCC after transplantation. Another objective of the study is to assess the treatment history (ablation or transarterial chemoembolization (TACE)) and size of the tumor with respect to the risk of MVI.

Methods: A single center, retrospective chart review, …

Barriers And Facilitators To Deaf Trauma Survivors’ Help-Seeking Behavior: Lessons For Behavioral Clinical Trials Research: A Master’S Thesis, Melissa L. Anderson Aug 2016

Barriers And Facilitators To Deaf Trauma Survivors’ Help-Seeking Behavior: Lessons For Behavioral Clinical Trials Research: A Master’S Thesis, Melissa L. Anderson

Melissa L. Anderson

Deaf individuals experience significant obstacles to participating in behavioral health research when careful consideration is not given to accessibility in the design of study methodology. To inform such considerations, we conducted a secondary analysis of a mixed-methods study that explored 16 Deaf trauma survivors’ help-seeking experiences. Our objective was to identify key findings and qualitative themes from consumers' own words that can be applied to the design of behavioral clinical trials methodology. In many ways, the themes that emerged are what we would expect of any research participant, Deaf or hearing – a need for communication access, empathy, respect, strict …

The objective of this study was to identify similarities and differences between college women and men with respect to their eating and body image concerns, weight fluctuation and level of motivation to resolve these concerns. 101 University of Dayton students participated in this study. Students completed an eating and body concern survey online.

Body image concerns were significantly greater for females compared to males (p=0.007) and significantly greater as motivation level to resolve the concerns increased (p=0.019). Eating concerns followed the same trends but did not reach statistical significance. Weight fluctuation in both genders increased significantly as motivation level increased …


The Mind-Body Connection: The Association Between Adolescent Locus Of Control And Indicators Of Physical Health, C. Brahler, James Cropper Dec 2015

The Mind-Body Connection: The Association Between Adolescent Locus Of Control And Indicators Of Physical Health, C. Brahler, James Cropper

C. Jayne Brahler

Locus of control (LOC) describes an individual’s generalized beliefs or expectancies that their reinforcements are under internal versus external control (1). An individual exhibits either an internal or external LOC. This study examines the link between LOC and selected health risk factors in adolescents. A convenience sample of 167 high school physical education students completed a 13-item LOC questionnaire based on Rotter’s 1966 instrument. Various anthropometric measurements, blood pressure, body mass index (BMI), and body fat were recorded on all subjects. A subsample of 61 female students received blood chemistry analysis that included a lipid profile, hemoglobin A1c (HbA1c), Apo …


Numerous Test Items In The Complete And Short Forms Of The Bot-2 Do Not Contribute Substantially To Motor Performance Assessments In Typically Developing Children Six To Ten Years Old, C. Brahler, Betsy Donahoe-Fillmore, Sara Mrowzinski, Susan Aebker, Megan Kreill Dec 2015

Numerous Test Items In The Complete And Short Forms Of The Bot-2 Do Not Contribute Substantially To Motor Performance Assessments In Typically Developing Children Six To Ten Years Old, C. Brahler, Betsy Donahoe-Fillmore, Sara Mrowzinski, Susan Aebker, Megan Kreill

C. Jayne Brahler

The purposes of the current study were (1) to determine the magnitude of association between individual subtest items and the respective total subtest scores on the four subtests in the Bruininks-Oseretsky Test of Motor Proficiency, second edition (BOT-2) and (2) to review items on the BOT-2 Short Form. The correlation coefficients (r) between ranged from .865 to .071. Several items suffered from a ceiling effect, and four of the eight items on the Short Form for these four subtests had very low associations with their subtest total score. These results raise several issues with the BOT-2 that warrant further investigation.

Vaccine-Preventable Diseases In Travelers, Edith Mirzaian, Jeffery Goad, Ani Amloian, Fady Makar Jan 2015

Vaccine-Preventable Diseases In Travelers, Edith Mirzaian, Jeffery Goad, Ani Amloian, Fady Makar

Jeff Goad

Travel to the developing world is increasing among those from developed countries, placing them at risk for vaccine preventable and non-vaccine preventable diseases. From 2007-2011, the GeoSentinel Network reported 737 returned travelers with a vaccine preventable disease. While it is essential that clinicians use vaccines when available for a disease of risk, they should also be aware that the vast majority of diseases acquired by travelers are non-vaccine preventable. The vaccine preventable diseases can be divided into routine travel vaccines, special travel vaccines and routine vaccines used for travel. The routine travel vaccines include Hepatitis A and B, typhoid; special …

Methods For Evaluating Prediction Performance Of Biomarkers And Tests, Margaret S. Pepe Phd, Holly Janes Phd Dec 2012

Methods For Evaluating Prediction Performance Of Biomarkers And Tests, Margaret S. Pepe Phd, Holly Janes Phd

Margaret S Pepe PhD

This chapter describes and critiques methods for evaluating the performance of markers to predict risk of a current or future clinical outcome. We consider three criteria that are important for evaluating a risk model: calibration, benefit for decision making and accurate classification. We also describe and discuss a variety of summary measures in common use for quantifying predictive information such as the area under the ROC curve and R-squared. The roles and problems with recently proposed risk reclassification approaches are discussed in detail.


Challenges And Opportunities For Developing Countries From Medical Tourism, Avinash M. Waikar, Samuel D. Cappel, Uday S. Tate Aug 2012

Challenges And Opportunities For Developing Countries From Medical Tourism, Avinash M. Waikar, Samuel D. Cappel, Uday S. Tate

Uday S. Tate

Wikipedia defines “Medical Tourism” as the act of traveling to other countries to obtain medical, dental and surgical care. Rapid expansion of facilities for patients abroad has helped to spur this industry’s growth. Regardless of the destination, U.S. citizens are increasingly embracing the benefits of medical tourism due to dramatically rising U.S. healthcare costs. Medical care in countries such as India, Mexico, Thailand and Singapore can cost as little as ten percent of the cost of comparable care in the U.S. for some procedures. Statistical analysis revealed the costs to be significantly lower for many of these countries. Currently, patients …
