Return To Play: Impact Of Urbanicity And Socioeconomic Status On Parents’ Attitudes Regarding Their Children's Play And Sport During The Covid-19 Pandemic, Kendall Saravanamuttoo

Electronic Thesis and Dissertation Repository

The COVID-19 pandemic has had a profound impact on the daily routines of parents and children. The primary aim of this study was to explore the influence of socioeconomic status (SES) and urbanicity on parents’ attitudes toward their children’s active play opportunities 6 months and 1.5 years into COVID-19. The secondary objective was to explore how parents’ attitudes at 6 months related to the structured and unstructured play opportunities that children returned to 1 year later, while moderating the effects of SES and urbanicity. A sample of 239 Ontario parents of children (< 12) completed two online surveys (August – December 2020; 2021). In general, parents in communities with urban features (e.g., densely populated areas), single-parents, full-time employed parents, and parents of lower-income were more hesitant to return their children to active play during the pandemic. Findings from this work highlight SES and urbanicity disparities that continue to exist during COVID-19.

Electronic Thesis and Dissertation Repository

MAiD became legally accessible to Canadians with a grievous and irremediable illness in June of 2016. As I write in 2023, MAiD has been expanded to include patients who do not have a foreseeable death, with anticipated inclusion of those with mental illness as a sole underlying medical condition (MI-SUMC) in 2024. As MAiD now accounts for over 3% of all deaths annually in Canada, there is a growing impetus to explore ways by which MAiD practice can be improved and care can be extended to the family members following the death of a patient.

Regulation Of Mhc Ii Trafficking And Expression By Host And Viral Factors, Alex Lac

Electronic Thesis and Dissertation Repository

Antigen presentation by major histocompatibility complex class II (MHC II) to the adaptive immune system is crucial for mounting sterilizing immune responses. This central role has made antigen presentation a target for antagonism by many pathogens. Notably, infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) decrease MHC II expression in several immune cells. The mechanisms responsible for this suppression are unknown but involves either redirecting MHC II molecules away from the cell surface or inhibiting MHC II expression. To understand how pathogens manipulate intracellular MHC II trafficking, we first investigated the role of the Golgi trafficking regulator, ERC1, in …

In this thesis we evaluated cognitive and psychological changes approximately five weeks after a wide range of symptoms in COVID-19 illness and determined whether advanced diffusion magnetic resonance imaging measures within subcortical brain structures of the limbic system were related to neurological, respiratory, psychiatric, and gastric symptoms experienced during the acute phase of illness. Cognitive and neuropsychological evaluations were performed in 45 participants who experienced neurological symptoms during the acute phase of COVID-19 illness. Participants also underwent …

Automation Through Deep-Learning To Quantify Ventilation Defects In Lungs From High-Resolution Isotropic Hyperpolarized 129xe Magnetic Resonance Imaging, Tuneesh Kaur Ranota

Electronic Thesis and Dissertation Repository

Obstructive lung diseases are characterized by heterogenous ventilation. Hyperpolarized ¹²⁹Xe gas lung magnetic resonance imaging (MRI) can examine lung ventilation heterogeneity by acquiring high-resolution isotropic images. The current gold standard of semi-automated (SA) segmentation can be used to quantify non-isotropic ¹²⁹Xe lung images to generate ventilation defect percent (VDP), however, this method is not suitable for analysis of isotropic voxel ¹²⁹Xe images due to the large number of slices. Therefore, we used a fully automated deep learning-based (DL) lung algorithm to calculate VDP from isotropic images. SNR, SA and DL-based VDP were calculated, showing a strong positive …
