Potential Health Impacts Of Heavy Metals On Hiv-Infected Population In Usa, Xiaohui Xu, Hui Hu, Amy B. Dailey, Greg Kearney, Evelyn O. Talbott, Robert L. Cook

Health Sciences Faculty Publications

Purpose: Noninfectious comorbidities such as cardiovascular diseases have become increasingly prevalent and occur earlier in life in persons with HIV infection. Despite the emerging body of literature linking environmental exposures to chronic disease outcomes in the general population, the impacts of environmental exposures have received little attention in HIV-infected population. The aim of this study is to investigate whether individuals living with HIV have elevated prevalence of heavy metals compared to non-HIV infected individuals in United States.

Methods: We used the National Health and Nutrition Examination Survey (NHANES) 2003-2010 to compare exposures to heavy metals including cadmium, lead, and total …

Bone: An Acute Buffer Of Plasma Sodium During Exhaustive Exercise?, Tamara Hew-Butler, Kristin J. Stuempfle, Martin D. Hoffman

Health Sciences Faculty Publications

Both hyponatremia and osteopenia separately have been well documented in endurance athletes. Although bone has been shown to act as a “sodium reservoir” to buffer severe plasma sodium derangements in animals, recent data have suggested a similar function in humans. We aimed to explore if acute changes in bone mineral content were associated with changes in plasma sodium concentration in runners participating in a 161 km mountain footrace. Eighteen runners were recruited. Runners were tested immediately pre- and post-race for the following main outcome measures: bone mineral content (BMC) and density (BMD) via dual-energy X-ray absorptiometry (DEXA); plasma sodium concentration …

Effects Of Prior Acute Exercise On Circulating Cytokine Concentration Responses To A High-Fat Meal, Josef Brandauer, Rian Q. Landers-Ramos, Nathan T. Jenkins, Espen E. Spangenburg, James M. Hagberg, Steven J. Prior

Health Sciences Faculty Publications

High-fat meal consumption alters the circulating cytokine profile and contributes to cardiometabolic diseases. A prior bout of exercise can ameliorate the triglyceride response to a high-fat meal, but the interactive effects of exercise and high-fat meals on cytokines that mediate cardiometabolic risk are not fully understood. We investigated the effects of prior exercise on the responses of circulating tumor necrosis factor-a (TNF-a), interleukin-6 (IL-6), IL-8, leptin, retinol-binding protein 4 (RBP4), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), placental growth factor (PlGF), and soluble fms-like tyrosine kinase-1 (sFlt-1) to a high-fat meal. Ten healthy men were studied before …

Association Of Gastrointestinal Distress In Ultramarathoners With Race Diet, Kristin J. Stuempfle, Martin D. Hoffman, Tamara Hew-Butler

Health Sciences Faculty Publications

Context: Gastrointestinal (GI) distress is common during ultrarunning.

Purpose: To determine if race diet is related to GI distress in a 161-km ultramarathon.

Methods: Fifteen (10 male, 5 female) consenting runners in the Javelina Jundred (6.5 loops on a desert trail) participated. Body mass was measured immediately pre-race and after each loop. Runners reported if they had nausea, vomiting, abdominal cramps, and/or diarrhea after each loop. Subjects were interviewed after each loop to record food, fluid, and electrolyte consumption. Race diets were analyzed using Nutritionist Pro.

Results: Nine (8 male, 1 female) of 15 runners experienced GI distress including nausea …
