Vascular Insulin Resistance May Contribute To Health Disparities In People From The Rio Grande Valley, Philippe J. Dentino, Ryan P. Bialaszewski, Yu Lun Tai, Ryan D. Russell Feb 2023

Vascular Insulin Resistance May Contribute To Health Disparities In People From The Rio Grande Valley, Philippe J. Dentino, Ryan P. Bialaszewski, Yu Lun Tai, Ryan D. Russell

International Journal of Exercise Science: Conference Proceedings

Microvascular blood flow (MBF) increases postprandially in skeletal muscle in response to insulin to aid in myocyte glucose delivery. This MBF response is considered a measure of vascular insulin resistance and can be impaired with altered meal composition, obesity, type 2 diabetes mellitus (T2DM), and insulin resistance. Current studies indicate this MBF response to a mixed meal challenge (MMC) may identify vascular insulin resistance before typically-presenting serum biomarkers of insulin resistance, as it displays more sensitivity than when using an oral glucose challenge (OGC). However, it is unknown if healthy adults residing in the Rio Grande Valley (RGV), an area …

Postprandial And Fasting Lipopolysaccharide Levels In Healthy Hispanic Residents Of Southeast Texas With Positive Family History Of Type 2 Diabetes, Amanda J. Wheeler, Yu Lun Tai, Smaran Marupudi, Ryan D. Russell

International Journal of Exercise Science: Conference Proceedings

PURPOSE: Healthy people with a family history (FH+) of type 2 diabetes (T2D) display impaired metabolic and microvascular function prior to glucose intolerance, and are at greater risk for developing T2D. While mechanisms to explain this disparity are lacking, it is possible that intestinal permeability plays a role, as it is also linked with insulin resistance, glucose intolerance, and chronic inflammation. Lipopolysaccharides (LPS) act as an outer membrane component of gram-negative bacteria in intestines and play a role in inflammation and chronic disease when in circulation, thus serving as a surrogate measure of intestinal permeability. However, the link between FH+ …

Body Fat Percentage And Hormonal Intrauterine Device Use Are Independently Associated With Self-Reported Menstrual Regularity In Young Adult Females, Gabrielle Dehaven, Madelin R. Siedler, Christian Rodriguez, Sarah White, Alex Brojanac, Ethan Tinoco, Grant M. Tinsley Feb 2023

Body Fat Percentage And Hormonal Intrauterine Device Use Are Independently Associated With Self-Reported Menstrual Regularity In Young Adult Females, Gabrielle Dehaven, Madelin R. Siedler, Christian Rodriguez, Sarah White, Alex Brojanac, Ethan Tinoco, Grant M. Tinsley

International Journal of Exercise Science: Conference Proceedings

Menstrual regularity is a key indicator of energy availability, long-term bone density, and other important health information in females. The occurrence of a regular menstrual cycle indicates that an individual’s level of estrogen is supportive of strong bones and that they are achieving the caloric intake required to support their activity level. In contrast, an irregular menstrual cycle can be indicative of insufficient energy availability which may, over time, result in low bone mineral density and thus a higher risk of bone stress injuries. However, hormonal contraceptive use, including the rising use of intrauterine devices (IUDs), may mask these changes …

Impaired Erythropoietin Response To A Single Session Of Intermittent Hypoxia In Patients With Type 2 Diabetes, Frank Wojan, Sten Stray-Gundersen, Jiahui Zhao, Sophie Lalande

International Journal of Exercise Science: Conference Proceedings

Patients with type 2 diabetes (T2D) exhibit, on average, a 20% decline in maximal oxygen consumption when compared to healthy adults. Hemoglobin mass strongly correlates to maximal oxygen consumption. A reduced total blood volume has been observed in patients with T2D, suggesting that a reduced hemoglobin mass contributes to the decreased maximal oxygen consumption in this population. Hypoxia stimulates the release of erythropoietin (EPO), the hormone regulating red blood cell production. We previously showed that intermittent hypoxia, consisting of alternating short bouts of breathing hypoxic and normoxic air, increases EPO levels. PURPOSE: To determine the effect of a single …
