Beyond The Brain: A Study Of Α-Synuclein's Role In Bone And Adipose Tissue, Carolina A. Figueroa

Electronic Theses and Dissertations

α-Synuclein is a polypeptide encoded by the Snca gene, highly expressed in neurons, but it is also found in bones and adipose tissue. Co-expression analysis showed that Snca regulates skeletal homeostasis, and its deletion reduced estrogen deficiency-induced bone loss and weight gain. It is a major component of Lewy bodies (LB) in Parkinson’s disease (PD), leading to progressive immobilization and a range of nonmotor symptoms, including osteopenia, body composition alterations and insulin resistance. This thesis aimed to determine α-Synuclein’s intrinsic role in bone and adipose homeostasis. We discussed the PD pathophysiology emphasizing aspects of bone health and metabolism. By using …

Body Composition Assessment Results And Predicting Injury Patterns In Collegiate Musicians, Ellen Reinhold

Online Theses and Dissertations

Objective: It is known that a higher body mass index (BMI) is associated with increased risk of injury, but it is unknown whether there is an association between increased risk of injury and body composition. Currently the data comes from competitive sports, with little data in performing arts, specifically marching band. The primary aim of this study was to determine if body composition assessments can predict musculoskeletal injury (MSI) occurrence in marching band participants. Methods: Body composition was measured using a duel X-ray absorptiometry (DXA) scan at the beginning of both the fall 2018 and 2019 seasons. Data on injuries …

Nutrition, Body Composition And Physical Activity In Malignant Pleural Disease: Associations With Patient Outcomes And Response To An Exercise Intervention, Emily Jeffery

Theses: Doctorates and Masters

Background: Patients with malignant pleural disease (MPD) have advanced cancer and high symptom burden. Goals of patient care are to optimise health-related quality-of-life (HR-QoL) and participation in daily physical activities. Supportive care interventions such as nutrition and exercise could offer benefit to patients. However, there is a lack of information on the prevalence of low muscle mass (i.e., pre-sarcopenia), malnutrition, inactivity and poor physical functioning in patients with MPD. Additionally, little is known about the factors associated with development of pre-sarcopenia and malnutrition or their associations with patient outcomes.

Purpose: The objectives were to: 1) characterise physical activity levels and …
