New Publications

 

Dr. Mathew Tucker is a post-doc on the LIVEP research team. He is the first author on two new publications. Check out his work below. 
 
Blood flow regulation and oxidative stress during submaximal cycling exercise in patients with cystic fibrosis.
 

Matthew A. Tucker; Breana Berry; Nichole Seigler; Gareth W. Davison; John C. Quindry; Dabney Eidson; Kathleen T. McKie; & Ryan Harris
 
Background: The impact of blood flow regulation and oxidative stress during exercise in cystic fibrosis (CF) has yet to be investigated. Conclusion: These data suggest that patients with mild CF exhibit impaired blood flow regulation and an exaggerated oxidative stress response to submaximal exercise.

Spot Sample Urine Specific Gravity Does Not Accurately Represent Small Decreases in Plasma Volume in Resting Healthy Males.

Matthew A. Tucker; Cory L. Butts; Alf Z. Satterfield; Ashley Six; Evan C. Johnson; & Matthew S. Ganio

Background: Urine specific gravity is often used to assess hydration status, particularly around athletic competition, but it is unknown whether high urine specific gravity is indicative of plasma volume (PV) reduction (i.e., hypohydration). We tested the hypothesis that if high urine specific gravity is reflective of reduced PV, subsequent fluid ingestion would increase PV. Conclusions: Despite a high preintervention urine specific gravity and subsequent decrease after 24-hour fluid intake, measures of PV and BV were not indicative of this seemingly improved hydration status. This suggests that a highly concentrated spot sample urine specific gravity and subsequent changes are not accurately representative of PV or BV.

A whole brain volumetric approach in overweight/obese children: Examining the association with different physical fitness components and academic performance.
The Active Brains project.

Esteban-Cornejo, I; Cadenas-Sanchez, C; Contreras-Rodriguez, O; Verdejo-Roman, J; Mora-Gonzalez, J; Migueles, JH; Henriksson, P; Davis, CL; Verdejo-Garcia, A; Catena, A; Ortega, FB.

Objective: Obesity, as compared to normal weight, is associated with detectable structural differences in the brain. To the best of our knowledge, no previous study has examined the association of physical fitness with gray matter volume in overweight/obese children using whole brain analyses. Thus, the aim of this study was to examine the association between the key components of physical fitness (i.e. cardiorespiratory fitness, speed-agility and muscular fitness) and brain structural volume, and to assess whether fitness-related changes in brain volumes are related to academic performance in overweight/obese children. Conclusion: These findings suggest that increases in cardiorespiratory fitness and speed-agility may positively influence the development of distinctive brain regions and academic indicators, and thus counteract the harmful effect of overweight and obesity on brain structure during childhood.

A novel immunohistochemical score to predict early mortality in acute myeloid leukemia patients based on indoleamine 2,3 dioxygenase expression.
 

Mangaonkar, A; Mondal, A; Fulzule, S; Pundkar, C; Park, EJ; Jillela, A; Kota, V; Xu, H; Savage, NM; Shi, H; Munn, D. Kolhe, R.

Background: Indoleamine 2,3 dioxygenase-1 (IDO-1) is an enzyme in the kynurenine pathway which augments tumor-induced immune tolerance. Previous studies in childhood acute myeloid leukemia (AML) have shown a negative correlation of IDO-1 mRNA expression with outcomes. The aim of our study was to develop a practical and objective immunohistochemical technique to quantify IDO-1 expression on diagnostic bone marrow biopsies of AML patients in order to facilitate its use in routine clinical practice. Conclusion: In conclusion, ‘composite IDO-1 score’ is a prognostic tool that can help identify a certain subset of AML patients with ‘early mortality’. This unique subset of patients can potentially benefit from specific IDO-1 inhibitor therapy, currently in clinical trials.

Presentations

Addressing Weight and Weight-related Issues Using Mindfulness-Based
Services in Multi-Ethnic Contexts.

 
Jean L. Kristeller; Ruth Wolever; Vernon Barnes; Elissa Epel; Cassandra Vieten; & Barbara Laraia 

Will be presented at the Society of Behavior Medicine in April

Empirical support is rapidly growing for mindfulness-based interventions (MBI), yet the question remains whether such services are appropriate and acceptable to populations of minorities and lower SES. This is of particular concern with weight-related medical issues, including type II diabetes and cardiovascular problems, given the higher prevalence in these groups.  This paper provides an overview of MBIs for weight regulation and reviews evidence from randomized clinical trials (RCTs) enrolling individuals with varied racial and ethnic backgrounds.

Meet Amy Szoka!

Amy graduated in 2014 from Georgia Southern University with her Bachelors in Child & Family Development. After college, she took an internship position working in a alcohol and drug prevention program in Columbia County. Amy grew up in a small town on the outskirts of Savannah and planned to move back home after her internship. Well, here she is 4 years later, making Augusta her home. Amy was hired on as staff at the same place she did her internship and worked there for 3 and a half years. During that time she completed over 300 hours of prevention training and became a Certified Prevention Specialist for the state of Georgia. Two years ago she met the love of her life and got married in March of this year. Amy looks forward to this new stage in her life, both personally and professionally as a new employee of Augusta University.

Amy will be working with Dr. Tingen, and will be coordinating the new opioid misuse and abuse contract from the state of Georgia. Welcome Amy to the department of Population Health Sciences! 

Special Presentation
