An Experimental Evaluation Of Stop-Plosive And Fricative Consonant Intelligibility By Tracheoesophageal Speakers In Quiet And Noise, Sebastiano Failla

Electronic Thesis and Dissertation Repository

Despite functional levels of postlaryngectomy communication, individuals who undergo total laryngectomy and tracheoesophageal (TE) puncture voice restoration continue to experience significant communication difficulties in noisy environments. In an effort to identify and further characterize TE speakers’ intelligibility in noise, the current auditory perceptual study investigated stop-plosive and fricative intelligibility of TE speech in quiet and in the presence of multi-talker noise. Eighteen listeners evaluated monosyllabic consonant-vowel-consonant words produced by 14 TE speakers using an open-response paradigm. Our findings indicate that overall intelligibility was significantly lower in noise. Further examination showed a differential effect of noise on intelligibility according to manner ...

Differences In Quadriceps Muscle Layer Thickness (Qmlt) And Contributing Risk Factors To Muscle Mass In Community-Dwelling And Institutionalized Older Adults, Nesrine Cheikh

Electronic Thesis and Dissertation Repository

Sarcopenia, a major concern in the older adult population, is defined as age-related loss of muscle mass and strength. Quadriceps muscle layer thickness (QMLT) measured using ultrasonography (US) is a newly-validated tool to measure muscle mass, which can be used to identify sarcopenic individuals. Our objective was to determine the association of factors such as handgrip strength (HGS), protein intake, nutritional status (via Subjective Global Assessment-SGA) and fat mass (FM) percentage with QMLT size (measured by US) in community-dwelling and institutionalized older adults. Additionally, we aimed to understand how perceived food intake of protein-rich foods could have an impact actual ...


An Exploration Of The Nursing Leaders’ Experiences Addressing Indigenous Health In University Undergraduate Nursing Programs In Ontario, Danae Coggins Dec 2018

An Exploration Of The Nursing Leaders’ Experiences Addressing Indigenous Health In University Undergraduate Nursing Programs In Ontario, Danae Coggins

Electronic Thesis and Dissertation Repository

Introduction. Although there are serious health inequities experienced by Indigenous people compared to non-Indigenous people in Canada and racism and discrimination continues to be rife in health care environments, there remains a general lack of attention to Indigenous health (IH) in health professional education programs. In response, the Truth and Reconciliation Commission (TRC) has recommended this be addressed within health profession education, including nursing (Truth and Reconciliation Canada, 2015). However, there is a paucity of evidence describing the challenges and facilitators to incorporating IH into nursing education.

Methodology and Methods. This qualitative study employs interpretive description approaches informed by post-colonial ...


Evaluation Of Perioperative Peripheral Nerve Injury In Cardiac Surgery Using A Novel Automated Ssep Monitoring Device, Satoru Fujii Dec 2018

Evaluation Of Perioperative Peripheral Nerve Injury In Cardiac Surgery Using A Novel Automated Ssep Monitoring Device, Satoru Fujii

Electronic Thesis and Dissertation Repository

INTRODUCTION: The high incidence of peripheral nerve injury (PNI) in conventional cardiac surgery (CCS) is believed to result from mechanical injury during sternotomy and/or retraction of the sternum. Minimally invasive cardiac surgery (MICS) is a newly developed type of cardiac surgery which does not require sternotomy or retraction of the sternum. Since surgery related PNI can lead to serious problems for both the patients and care providers, the incidence and details of PNI in cardiac surgery needs to be investigated. OBJECTIVE: To compare the degree of nerve injury in MICS and CCS using somatosensory evoked potential (SSEP) signals. METHODS ...

Retrospective Motion Correction In Magnetic Resonance Imaging Of The Brain, Patricia Johnson Dec 2018

Retrospective Motion Correction In Magnetic Resonance Imaging Of The Brain, Patricia Johnson

Electronic Thesis and Dissertation Repository

Magnetic Resonance Imaging (MRI) is a tremendously useful diagnostic imaging modality that provides outstanding soft tissue contrast. However, subject motion is a significant unsolved problem; motion during image acquisition can cause blurring and distortions in the image, limiting its diagnostic utility. Current techniques for addressing head motion include optical tracking which can be impractical in clinical settings due to challenges associated with camera cross-calibration and marker fixation. Another category of techniques is MRI navigators, which use specially acquired MRI data to track the motion of the head.

This thesis presents two techniques for motion correction in MRI: the first is ...


Social Inclusion For Women Experiencing Homelessness, Jenna Richards Dec 2018

Social Inclusion For Women Experiencing Homelessness, Jenna Richards

Electronic Thesis and Dissertation Repository

Background: People experiencing homelessness have been described as one of the most socially excluded groups in society due to their inequitable access to basic necessities (Everett 2009; Labonte, 2004). Particular consideration regarding social inclusion should be given to the unique vulnerabilities of sub-populations of those experiencing homelessness, such as women (Wesely & Wright, 2005) due to their increased rates of ‘hidden homelessness’ (Walsh et al., 2009) and experiences of violence and discrimination (Roschelle, 2017; Weiser et al., 2009). Community participation, particularly sports activities, have been cited as one method towards increasing social inclusion among people experiencing homelessness. However, differential access to sport activities have been found for women experiencing homelessness (Oudshoorn, Misener, Richards, unpublished). Exploring the barriers and facilitators to social inclusion for ...

Investigating The Practical And Clinical Effectiveness Of Applying Current Steering To Deep Brain Stimulation For Parkinsonian Gait Therapy, Daphne Hui Dec 2018

Investigating The Practical And Clinical Effectiveness Of Applying Current Steering To Deep Brain Stimulation For Parkinsonian Gait Therapy, Daphne Hui

Electronic Thesis and Dissertation Repository

Multiple neural network integration, influence of bradykinesia and rigidity, and bias of upper limb symptom improvement during deep brain stimulation implementation may attribute to the variable responsiveness of Parkinsonian gait therapy. Current steering (CS) addresses variability through fractionating current to fine-tune the stimulation field shape. It was hypothesized that CS would exhibit greater gait improvements and lower the total electrical energy delivered (TEED), which reduces power consumption and battery drainage. Divisions of 70/30 and 50/50 and single-contact stimulation modelled CS and conventions, respectively. Overall ambulation improved with TEED reduction; further, bilateral CS improved step time and length but ...

Exploring Social Cohesion Among Syrian Refugees In Canada: A Secondary Analysis, Sara Calvert

Electronic Thesis and Dissertation Repository

BACKGROUND: As a result of the ongoing crisis in Syria, more than 11 million people have been displaced or killed over the past seven years (Mercy Corps, 2018). Despite efforts by the Canadian government to increase refugee uptake and promote social cohesion, refugees may still face negative resettlement experiences (Galabuzi, 2006; McCoy, Kirova, & Knight, 2016). Exploring how Syrian refugees have experienced social cohesion within their first year in Canada may help to address resettlement needs.

METHODS: This study was a secondary analysis on data collected from the Housing Education for Syrian Refugees and their Landlords study, which evaluated the impact ...


Investigating The Role Of Endogenous Atf4 Upregulation On Neuronal Glutathione Level, Fatemeh Mirshafiei Dec 2018

Investigating The Role Of Endogenous Atf4 Upregulation On Neuronal Glutathione Level, Fatemeh Mirshafiei

Electronic Thesis and Dissertation Repository

ATF4 is a transcription factor that is activated in response to integrated stress response (ISR). In neurons specifically, ATF4 has been suggested to act as a pro-apoptotic transcription factor. The expression of ATF4, as well as its downstream gene targets have been implicated in both in vivo and in vitro models of Alzheimer’s and Parkinson’s Disease. However, the mechanism by which ATF4 promotes cell death remains unclear. It was previously shown that overexpression of ATF4 in primary cortical neurons caused a reduction in glutathione levels, resulting in oxidative stress-induced cell death. The aim of this project was to ...

Conceptual Disorganization And Redistribution Of Resting State Cortical Hubs In Drug-Naive First Episode Psychosis: A 7t Functional Magnetic Resonance Imaging Study, Avyarthana Dey

Electronic Thesis and Dissertation Repository

Network level dysconnectivity has been studied in positive and negative symptoms of schizophrenia. Conceptual disorganization (CD) is a symptom which predicts impaired real-world functioning. Systematic reviews have reported aberrant connectivity in formal thought disorder, a construct related to CD. However, no studies have investigated whole-brain functional correlates of CD in psychosis. We sought to investigate brain regions explaining the severity of CD in patients with first-episode psychosis (FEPs) compared with healthy controls (HCs). We computed whole-brain binarized degree centrality maps of 31 FEPs, 25 HCs and characterized the patterns of network connectivity in the two groups. In FEPs, we related ...

In Vivo Tracking Of Tumour Associated Macrophages In Breast Cancer With Magnetic Resonance Imaging, Ashley V. Makela Nov 2018

In Vivo Tracking Of Tumour Associated Macrophages In Breast Cancer With Magnetic Resonance Imaging, Ashley V. Makela

Electronic Thesis and Dissertation Repository

Introduction: The environment in which a tumour exists and functions is called the tumour microenvironment (TME). In breast cancer, the presence of tumour associated macrophages (TAMs) in the TME is associated with tumour aggressiveness and poor outcomes. Despite evidence for a link between TAM content and outcome, there are few strategies to measure TAMs and no in vivo approach. Iron or fluorine-19 (19F)-based MRI can be used to detect macrophages post intravenous injection of either an iron or perfluorocarbon (PFC) agent. Iron-based MRI is sensitive but difficult to quantify. 19F MRI is specific and signal is proportional ...


Cognitive Impairment And The Mediterranean Diet: A Canadian Perspective, Ivan Culum Nov 2018

Cognitive Impairment And The Mediterranean Diet: A Canadian Perspective, Ivan Culum

Electronic Thesis and Dissertation Repository

Global life expectancy has increased steadily over the past century and is projected to continue increasing. Life expectancy increases are co-occurring with a reduction of fertility rates in many economically developed countries, which is resulting in an aging population, meaning that the proportion of older adults within the total world population will continue to increase. This is of particular concern as there is a rise of chronic neurodegenerative diseases among older adults, such as dementia, where the number of global deaths more than doubled since the turn of the century, making dementia the fifth leading cause of death worldwide. Dementia ...

The Use Of Current Steering During Subthalamic Deep Brain Stimulation To Alleviate Upper Limb Symptoms Of Parkinson's Disease, Shabna Iftikar Mohideen Nov 2018

The Use Of Current Steering During Subthalamic Deep Brain Stimulation To Alleviate Upper Limb Symptoms Of Parkinson's Disease, Shabna Iftikar Mohideen

Electronic Thesis and Dissertation Repository

Subthalamic (STN) deep brain stimulation (DBS) is an established treatment to alleviate the appendicular motor symptoms of Parkinson's Disease (PD). Current steering during DBS allows the unequal fractionation of current between two electrodes on the lead, resulting in a non-spherical electrical field. It is hypothesized that the way the electrical field is shaped will affect a patient’s upper limb symptom alleviation. Seven PD patients who underwent bilateral STN-DBS were tested over four weeks post-operation. 16 current fractionation settings were tested each week at an amplitude that increased weekly. Optimal setting was defined as the setting that provided the ...


Collared Vs. Collarless Total Hip Arthroplasty In Both Direct Anterior And Direct Lateral Approach Surgery: A Prospective Cohort Comparison Study, Seb Heaven Nov 2018

Collared Vs. Collarless Total Hip Arthroplasty In Both Direct Anterior And Direct Lateral Approach Surgery: A Prospective Cohort Comparison Study, Seb Heaven

Electronic Thesis and Dissertation Repository

Total hip arthroplasty (THA) is one of the most successful surgical procedures performed worldwide. Recent advances in implant technology and popularization of the muscle-sparing Direct Anterior (DA) approach to the hip has led to younger patients becoming candidates for hip arthroplasty surgery. Among the many considerations necessary for success in this patient population, implant design plays an important role in determining outcomes.

In this thesis, we prospectively evaluated patients who received a collared or collarless fully hydroxyapatite-coated femoral stem during THA with a standard RSA protocol to assess stem migration patterns following surgery.

Preliminary results indicate that collarless stems subside ...

Cost Effectiveness Of Bilateral Prophylactic Mastectomy With And Without Different Breast Reconstruction Techniques Versus Screening In Women With High Risk Of Breast Cancer In The Canadian Province Of Ontario, Badria Aljohani

Electronic Thesis and Dissertation Repository

We aimed to investigate the cost-effectiveness of bilateral prophylactic mastectomy (BPM) with and without different reconstruction for the purpose of determining which strategies represent value for money. We developed a decision analytic model to project the lifetime clinical and economic consequences of different strategies. The decision model was parameterized using 10-year follow up and cost data from Ontario administrative health databases and Ontario Cancer registry. Compared to the organized screening-based strategy, surgical strategies ranged from being more effective and cost-saving and up to being associated with an incremental cost effectiveness ratio (ICER) of $63,010 per quality-adjusted life year (QALY ...


Multi-Scale Peripheral Vasculopathy With Metabolic Syndrome, Kent Lemaster Nov 2018

Multi-Scale Peripheral Vasculopathy With Metabolic Syndrome, Kent Lemaster

Electronic Thesis and Dissertation Repository

The combination of cardiovascular and metabolic risk factors including obesity, dyslipidemia, hypertension, and insulin resistance, in combination with a prothrombotic and proinflammatory state, is a condition termed Metabolic Syndrome (METS). Twenty percent of the adult population is afflicted with METS which increases the risk of type-2 diabetes mellitus and cardiovascular disease. Further, the presence of peripheral vascular disease (PVD) is tightly coupled with METS which is a perfusion-demand mismatch of blood supply to active skeletal muscle resulting in painful claudication and a late-stage potential for amputation. The underlying contributors of METS associated micro-vasculopathies in the skeletal muscle, their impact on ...


The Effect Of Function-Blocking Rhamm Peptides In A Mouse Model Of Bleomycin-Induced Systemic Sclerosis, Kitty Y. Wu Nov 2018

The Effect Of Function-Blocking Rhamm Peptides In A Mouse Model Of Bleomycin-Induced Systemic Sclerosis, Kitty Y. Wu

Electronic Thesis and Dissertation Repository

Systemic sclerosis is a chronic, fibrotic disorder associated with high disease-specific mortality and morbidity. Cutaneous manifestations include dermal thickening and obliteration of dermal adipose tissue. The efficacy of function-blocking Rhamm peptides, NPI-110 and NPI-106, were tested in reducing skin fibrosis and promoting adipogenesis in a bleomycin-induced mouse model of systemic sclerosis. NPI-110 reduced both visible measures of fibrosis (dermal thickness, collagen density, and fibril bundling) and mRNA expression of pro-fibrotic genes (Tgfb1, c-Myc, Col1a1, Col3a1). While there was no measurable change in dermal adipose thickness, NPI-110 treatment upregulated Perilipin mRNA and Adiponectin protein expression and is therefore hypothesized to create ...

The Work Of Self-Managing Attendant Services: A Reflexive Ethnographic Study, Erika Katzman Nov 2018

The Work Of Self-Managing Attendant Services: A Reflexive Ethnographic Study, Erika Katzman

Electronic Thesis and Dissertation Repository

In self-managed attendant services, disabled people organize and manage their own personal support services. ‘Self-managers’ take responsibility to recruit, hire, train and manage ‘attendants’ in order to have greater autonomy in attendant services, and in everyday life. Where the tasks associated with self-managing attendant services are often represented as responsibilities, this research begins with the assumption that these activities constitute work. Following critical disability studies and critical feminist scholarship, work is defined broadly as efforts made to organize and manage attendant services within self-managed models. The research presented adopts a reflexive ethnographic methodological approach to explore multiple perspectives on the ...


An Environmental Scan Of Settlement Services For The Integration Of Refugee Youth In Southwestern Ontario, Aparna Karky Nov 2018

An Environmental Scan Of Settlement Services For The Integration Of Refugee Youth In Southwestern Ontario, Aparna Karky

Electronic Thesis and Dissertation Repository

This environmental scan presents an overview of the settlement services and programs provided to refugee youth in Ontario for their integration and well-being. The settlement experiences of refugee youth, their needs and challenges, represent a burgeoning aspect of refugee integration studies. However, little attention has been paid to available settlement services within refugee integration studies. Since the facilitators and barriers pertaining to the integration of refugee youth are relatively well-documented, this environmental scan gathers and interprets information on the range of available settlement services and programs in respect to the indicators of integration for refugee youth in the cities of ...
