Sarcopenia In Head And Neck Cancer: A Prognostic Analysis, Nedeljko Jovanovic
Sarcopenia In Head And Neck Cancer: A Prognostic Analysis, Nedeljko Jovanovic
Electronic Thesis and Dissertation Repository
Introduction: In head and neck cancer (HNC), loss of skeletal muscle mass (SMM), or sarcopenia, is a strong prognostic factor for outcomes. However, inconsistencies in its assessment limit our understanding of the relationship between sarcopenia and nutrition-related outcomes. This project evaluated the significance of sarcopenia as described in the literature and as demonstrated in a cohort of HNC patients.
Methods: A scoping review was first conducted followed by a retrospective cohort study with data collected from 194 oropharyngeal carcinoma patients treated with definitive radiation/chemoradiation. Sarcopenia was assessed from computed tomography (CT) imaging at the third cervical vertebra (C3) and the …
The Difference In A1c Of Children And Adolescents With Type 1 Diabetes Mellitus Using Carbohydrate Counting Compared To Those Using A Structured Meal Plan, Alia El Kubbe
Electronic Thesis and Dissertation Repository
Carbohydrate counting (CHO) is a nutrition education tool used by patients with type 1 diabetes mellitus (T1DM). The primary objective was to assess glycated hemoglobin (A1C) in participants with T1DM using CHO counting vs. those using a structured meal plan (SMP). The secondary objectives were to determine if BMI-for-age, parental income, parental involvement, and mothers’ educational level were associated with their children’s glycemic control. A cross sectional study was conducted, where participants aged 4-18 years, or their parents completed a survey. Total sample size was 88 participants (77 in the CHO counting group and 11 in the SMP group). There …
Impact Of Feeding Tube Status On Health Outcomes For Individuals With Oropharyngeal Cancer, Nedeljko Jovanovic
Impact Of Feeding Tube Status On Health Outcomes For Individuals With Oropharyngeal Cancer, Nedeljko Jovanovic
Electronic Thesis and Dissertation Repository
Abstract
This study investigated differences in outcomes related to health, swallowing, and quality of life (QoL) for individuals with oropharyngeal squamous cell carcinoma (OPSCC) receiving either radiotherapy (RT) alone, or concomitant chemoradiotherapy (CRT). Differences were assessed based on whether patients received a feeding tube (FT group) or not (NFT group). Measures including the Functional Oral Intake Scale (FOIS), Performance Status Scale for Head and Neck Cancer (PSS-HN), M.D. Anderson Dysphagia Inventory (MDADI), and weight were collected for 126 individuals at baseline, and at 3, 6, and 12 months post-treatment. Data were analyzed to identify potential prognostic differences between the groups, …
Nutrition Screening In The Adult Stroke Population Using The Canadian Nutrition Screening Tool In Comparison With The Subjective Global Assessment, Tess Coutu
Electronic Thesis and Dissertation Repository
Although the Canadian Best Practice Recommendations for Stroke Care recommend all acute stroke patients be screened for malnutrition within 48 hours of admission to hospital using a valid screening tool, none have been validated for use in adult acute stroke patients. The Canadian Nutrition Screening Tool (CNST) tool has been validated within medicine and surgery patients. The purpose of this study is to estimate the level of agreement between the CNST and the Subjective Global Assessment (SGA), a nutrition assessment tool, in a cohort of 58 acute adult stroke patients at the Southwestern Ontario Regional Stroke Centre in London. In …
Molecular Mechanisms Linking Amino Acid (Leucine) Deprivation To Igfbp-1 Hyperphosphorylation In Fetal Growth Restriction, Niyati M. Malkani
Molecular Mechanisms Linking Amino Acid (Leucine) Deprivation To Igfbp-1 Hyperphosphorylation In Fetal Growth Restriction, Niyati M. Malkani
Electronic Thesis and Dissertation Repository
In this study, we explore the molecular mechanisms linking amino acid (leucine) deprivation to IGFBP-1 hyperphosphorylation in vitro. During pregnancy, a maladaptive fetal response to in utero amino acid deprivation leads to Fetal Growth Restriction (FGR). FGR infants display elevated phosphorylated IGFBP-1, which is associated with decreased IGF-I bioavailability. Leucine deprivation inhibits mechanistic target of rapamycin (mTOR) signaling and stimulates the amino acid response (AAR). Using HepG2 cells, a model for fetal hepatocytes, we demonstrate that in leucine deprivation, the AAR modulates total and phosphorylated IGFBP-1 while mTOR mediates total IGFBP-1 secretion only. We also reveal that protein kinases …
Evaluating The Impact Of Two Different Methods Of Diabetes Self-Management Education On Knowledge, Attitude, And Behaviours Of Patients With Type 2 Diabetes Mellitus, Laura B. Briden
Electronic Thesis and Dissertation Repository
This study compared the effectiveness of diabetes self-management education (DSME) methods by examining changes in knowledge, attitude, and behaviour (KAB) after receiving education. Participants from a convenience sample were randomized into two groups, one receiving education through conversation maps and the other through traditional group education. Participants’ knowledge and attitude changes were measured by using a repeated measures pre-test/post-test design and changes in Hb A1c were observed. Focus groups were conducted after education was received to obtain perceptions and self-reported behaviour changes. Significant knowledge and attitude score changes were observed in the conversation map group after education. When comparing the …
