How Can Single Mothers Care For Themselves And Their Children During The Covid-19 Pandemic?, Lisbeth Alexandra Pino Gavidia

Electronic Thesis and Dissertation Repository

This work investigates how single mothers maintain healthy behaviours for themselves and their children as they try to meet the evolving COVID-19 public recommendations. Everyone has had to adapt to changing public health rules. Single mothers may have unique challenges as they juggle to adapt to changing family responsibilities since they do not have another person helping in the home, and help outside the home may be restricted by public health rules. My research plan addressed these questions to learn more about the experiences of single mothers during the pandemic: 1) What are the changes in family responsibilities? 2) How …

Racial Inequalities In Booster Shot Uptake: Black Communities In The City Of Toronto, Anjali Bhaheeratha

Undergraduate Student Research Internships Conference

The unequal distribution of COVID-19 vaccines has posed a threat to the health and wellbeing of various marginalized communities, including Black communities. The booster shot in particular is not a mandatory vaccine, raising questions whether this would further vaccine inequity. I, along with Dr. Kate Choi of the Sociology Department at Western University, analyzed vaccination rates of the first booster shot across all 140 neighborhoods in the City of Toronto. Through stratifying neighborhoods based on the prevalence of Black residents and high/low socioeconomic status, it is clear to see that race, in tandem with similar socio-demographic characteristics, plays a significant …

A Collaborative Approach To Caring For Refugees In The Covid-19 Pandemic, Sara Mojdehi

Undergraduate Student Research Internships Conference

With higher cases rates, it is clear that newcomer and refugee populations in Ontario have been disproportionately affected by the COVID-19 pandemic. These vulnerable populations generally work in settings that increase their risk of infection and do not offer sick leave (ICES, 2021). In addition, overcrowded and multigenerational housing make it difficult for these individuals to adhere to self-isolation guidelines. Language and cultural barriers among refugee populations have also limited their access to information about the virus, making it challenging to follow public health measures (ICES, 2021).

The increased likelihood of an outbreak in these communities manifested itself in London, …

(Re) Evaluating Critical Care Nurse Support Program(S) In A Tertiary Care Hospital: Intersecting The Art And Science Of Nursing, C. Patricia Mazzotta

The Dissertation in Practice at Western University

There is a growing critical care nurse staffing shortage with increases in nurse vacancy rates. Moral distress has been exacerbated by the SARS-CoV-2 (COVID-19) pandemic and, in particular, impacting critical care nurses. COVID-19 is a significant contributor to staffing shortages and continued nursing crisis. Thus, the impetus for the Problem of Practice (PoP): the lack of support to address the psychological, emotional, and spiritual distress suffered by critical care registered nurses in a tertiary care hospital in Central Ontario. To comprehend the realities of working in the intensive care units, leaders must first understand nurses’ lived experiences, narratives, and what …

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 …

Characterizing And Predicting Canadian Adolescents’ Internalizing Symptoms In The First Year Of The Covid-19 Pandemic, Haley Elizabeth Green

Electronic Thesis and Dissertation Repository

Most studies of adolescents’ internalizing symptoms during the COVID-19 pandemic have included few data waves, limiting long-term conclusions about adolescents’ mental health during the pandemic. Collecting only a few waves of data precludes examination of intraindividual symptom variability, which may have implications for adjustment beyond mean symptoms. We characterized mean n = 192 adolescents’ internalizing symptoms from March 2020-April 2021 and used mixed effect location scale models to examine established risk factors as predictors of mean trends and intraindividual variability in adolescents’ internalizing symptoms. Adolescents’ symptoms were relatively stable and low over the first year of the pandemic; severity peaked …

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 …
