Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry
Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry
Senior Honors Theses
Low energy availability (LEA) is a state in which energy intake is insufficient to support energy expenditure while maintaining energy balance, which has been shown to result in gastrointestinal distress, immunosuppression, reduced metabolic rate, menstrual dysfunction, diminished bone health, and impaired cardiovascular function in females. Alterations to the microbiome and mucosal lining may propagate gastrointestinal complaints and compromised immune function associated with LEA. The pathophysiology of LEA is otherwise largely driven by hormonal adaptations. Diminished production of thyroid hormones is known to contribute to reduced metabolic rate. Decreases in leptin and insulin and increases in ghrelin disrupt reproductive function through …
A Muscle Cell-Macrophage Axis Involving Matrix Metalloproteinase 14 Facilitates Extracellular Matrix Remodeling With Mechanical Loading, Bailey D. Peck, Kevin A. Murach, R. Grace Walton, Alexander J.

The extracellular matrix (ECM) in skeletal muscle plays an integral role in tissue development, structural support, and force transmission. For successful adaptation to mechanical loading, remodeling processes must occur. In a large cohort of older adults, transcriptomics revealed that genes involved in ECM remodeling, including matrix metalloproteinase 14 (MMP14), were the most upregulated following 14 weeks of progressive resistance exercise training (PRT). Using single-cell RNA-seq, we identified macrophages as a source of Mmp14 in muscle following a hypertrophic exercise stimulus in mice. In vitro contractile activity in myotubes revealed that the gene encoding cytokine leukemia inhibitory factor ( …

Integration Of Consumer-Based Activity Monitors Into Clinical Practice For Children With Type 1 Diabetes: A Feasibility Study, Jason R. Jaggers, Timothy Mckay, Kristi M. King, Bradly J. Thrasher, Kupper A. Wintergerst

Current technology commonly utilized in diabetes care includes continuous glucose monitors (CGMs) and insulin pumps. One often overlooked critical component to the human glucose response is daily physical activity habits. Consumer-based activity monitors may be a valid way for clinics to collect physical activity data, but whether or not children with type 1 diabetes (T1D) would wear them or use the associated mobile application is unknown. Therefore, the purpose of this study was to test the feasibility of implementing a consumer-based accelerometer directly into ongoing care for adolescents managing T1D. Methods: Adolescents with T1D were invited to participate in this …
Rising Rural Body-Mass Index Is The Main Driver Of The Global Obesity Epidemic In Adults, Con Burns, Tara Coppinger, Janette Walton, Et Al
Rising Rural Body-Mass Index Is The Main Driver Of The Global Obesity Epidemic In Adults, Con Burns, Tara Coppinger, Janette Walton, Et Al

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity3,4,5,6. Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to …

Background—Metabolic syndrome (MetS) has been linked with an increased risk of developing cancer; however the association between MetS and cancer mortality remains less clear. Little research has focused on pre-cancer risk factors that may affect the outcome of treatment. The purpose of this study was to examine the association between MetS and all-cancer mortality in men. Methods—The participants included 33,230 men aged 20-88 years who were enrolled in the Aerobics Center Longitudinal Study and free of known cancer at baseline. Results—At baseline 28% of all the participants had MetS. During an average of 14 years followup there were a total …

The inclusion of regular physical activity is critical for optimal insulin action and glycemic control in individuals with diabetes. Current research suggests that Type II diabetes mellitus can be prevented and that all types of diabetes can be controlled with physical activity, largely through improvements in muscular sensitivity to insulin. This article discusses diabetes prevention and the acute and chronic benefits of exercise for individuals with diabetes, along with the importance and impact of aerobic, resistance, or combined training upon glycemic control. To undertake physical activity safely, individuals also must learn optimal management of glycemia.

By the late 1960s, the increasing number of type 2 diabetic cases in children and adolescents rapidly presented a signifi cant public health issue recognized by the American Diabetes Association (2000). Since then, the prevalence of pediatric type 2 diabetes appears to be on the rise not only in the United States but all around the world (Gungor et al., 2005). In the United States, an increase from fewer than four percent to more than 50 percent of new cases of type 2 diabetes in the pediatric population was reported between the years of 1982 and 1998 (American Diabetes Association, …

In diabetic individuals, increased shunting of circulation away from the skin may exist, contributing to their greater risk for ulcerations and poor cutaneous healing. In a prospective study (1), we previously found a lower skin perfusion during local heating in the foot dorsum of sedentary type 2 diabetic individuals compared with active people without diabetes. This defect was present despite normal increases in skin interstitial nitric oxide (NO), suggesting that NO is either ineffective or not involved (2). A prior bout of maximal exercise also lessened the impaired responsiveness to local heating of the dorsal foot in active type 2 …
