BACKGROUND: Cannabis is a risk factor in the onset and persistence of psychotic disorders. There is concern that non-medical cannabis legalization in Canada may have population-level impacts on psychotic disorders. We sought to examine changes in health service use and incident cases of psychotic disorder following cannabis legalization, during a period of tight restrictions on retail stores and product types.

METHODS: We conducted a cross-sectional interrupted time-series analysis using linked population-based health administrative data from Ontario (Canada) from January 2014 to March 2020. We identified psychosis-related outpatient visits, emergency department visits, hospitalizations, and inpatient length of stay, as well as …

Clinical Characteristics And Outcomes Of Patients With Idiopathic Intracranial Hypertension In East Africa: A Retrospective Cross-Sectional Study, Zian Muikamba

Master of Internal Medicine

Introduction; Idiopathic intracranial hypertension (IIH) is a neurological condition characterized by elevated intracranial cerebrospinal fluid (CSF) pressure without demonstratable evident causes. The mechanisms leading to a particular predilection for women of childbearing age who are overweight and obese or who have recent rapid weight changes remain imprecisely described. The Modified Dandy criteria is used for diagnosis and includes-clinical symptoms, papilledema, lumbar puncture (LP) opening pressure, and neuroimaging. If undiagnosed, it can progress to disabling irreversible visual loss. Weight loss is useful in addition to medical therapy in treating the condition. Data in Sub-Saharan Africa is scarce.

Methods; This study described …

Impacts Of Climate Change On Vector-Borne Disease Burden In The United States: Exploring The Epidemiological Evidence, Leah V. Loetman

Honors Theses

Climate change models predict shifts in vector-borne diseases (VBDs) around the world, including in the United States. However, to my knowledge there has yet to be a comprehensive descriptive epidemiological study examining prevalence, geographic distribution, and trends for all tick- and mosquito-borne diseases in the United States. I compiled data from the U.S. Centers for Disease Control (CDC), which publishes yearly case numbers for 17 vector-borne diseases. However, these publications depend on a scattered framework of state regulations regarding disease reporting. I compiled data from the CDC to determine the current geographic distribution, prevalence, and trends of tick- and mosquito-borne …

Different Cohort, Disparate Results: Selection Bias Is A Key Factor In Autopsy Cohorts, Kathryn Gauthreaux, Walter A. Kukull, Karin B. Nelson, Charles Mock, Yen-Chi Chen, Kwun C. G. Chan, David W. Fardo, Yuriko Katsumata, Erin L. Abner, Peter T. Nelson

Neurology Faculty Publications

INTRODUCTION: Research-oriented autopsy cohorts provide critical insights into dementia pathobiology. However, different studies sometimes report disparate findings, partially because each study has its own recruitment biases. We hypothesized that a straightforward metric, related to the percentage of research volunteers cognitively normal at recruitment, would predict other inter-cohort differences.

METHODS: The National Alzheimer’s Coordinating Center (NACC) provided data on N = 7178 autopsied participants from 28 individual research centers. Research cohorts were grouped based on the proportion of participants with normal cognition at initial clinical visit.

RESULTS: Cohorts with more participants who were cognitively normal at recruitment contained more individuals who …

Applying Market Basket Analysis To Determine Complex Coassociations Among Food Allergens In Children With Food Protein-Induced Enterocolitis Syndrome (Fpies), Ankona Banerjee, Kenneth Nobleza, Cynthia Haddad, Joshua Eubanks, Ruchit Rana, Nicholas L Rider, Lisa Pompeii, Duc Nguyen, Sara Anvari

Faculty, Staff and Students Publications

BACKGROUND: Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy, characterized by delayed onset of repetitive vomiting occurring 1 to 4 h following ingestion of a food allergen. Managing FPIES requires strict avoidance of the food trigger. The concern with FPIES is determining the risk of another FPIES food trigger reaction due to potential coassociations with other foods or food groups. An effective statistical approach for analyzing FPIES-related data is essential to identify common coallergens and their associations.

METHODS: This study employed Market Basket Analysis, a data-mining technique, to examine correlations and patterns among allergens in FPIES patients at …

Genetic Risk Scores For Hypertension And Chronic Kidney Disease In African Americans., Aastha Kakar

Electronic Theses and Dissertations

Hypertension (HT) and chronic kidney diseases (CKD) are complex conditions, disproportionally prevalent among African Americans (AA) and are influenced by multiple genetic as well as environmental factors. Genetic risk scores (GRS) enable the analysis of the combined effects of multiple single nucleotide polymorphisms (SNPs). This study investigates the association of blood pressure (BP) and CKD GRS with BP, hypertension (HT) and CKD; early-onset HT and CKD; and investigates interactions of the GRSs with environmental measures in AA. We observed a significant association between the BP-GRS with HT, SBP and DBP. The odds of HT for one standard deviation (s.d.) increase …

BACKGROUND: There are few assessments evaluating associations between birth defects with neural crest cell developmental origins (BDNCOs) and embryonal tumors, which are characterized by undifferentiated cells having a molecular profile similar to neural crest cells. The effect of BDNCOs on embryonal tumors was estimated to explore potential shared etiologic pathways and genetic origins.

METHODS: With the use of a multistate, registry-linkage cohort study, BDNCO-embryonal tumor associations were evaluated by generating hazard ratios (HRs) and 95% confidence intervals (CIs) with Cox regression models. BDNCOs consisted of ear, face, and neck defects, Hirschsprung disease, and a selection of congenital heart defects. Embryonal …

Building Up A Genomic Surveillance Platform For Sars-Cov-2 In The Middle Of A Pandemic: A True North-South Collaboration, Waqasuddin Khan, Furqan Kabir, Samiah Kanwar, Fatima Aziz, Sahrish Muneer, Adil Kalam, Mehdia Ali, Nadia Ansari, Fyezah Jehan, Muhammad Imran Nisar

Department of Paediatrics and Child Health

Next-generation sequencing technology has revolutionised pathogen surveillance over the last two decades. However, the benefits are not equitably distributed, with developing countries lagging far behind in acquiring the required technology and analytical capacity. Recent declines in the cost associated with sequencing-equipment and running consumables have created an opportunity for broader adoption. During the COVID-19 pandemic, rapid diagnostics development and DNA sequencing revolutionised the ability to diagnose and sequence SARS-CoV-2 rapidly. Socioeconomic inequalities substantially impact the ability to sequence SARS-CoV-2 strains and undermine a developing country's pandemic preparedness. Low- and middle-income countries face additional challenges in establishing, maintaining and expanding genomic …

BACKGROUND: Toxocariasis, caused the by dog and cat roundworm, is one of the most common zoonotic helminth infections in the United States and can lead to severe lifelong morbidity in children. Although historical seroprevalence studies have identified a high frequency of toxocariasis regionally in the United States, there are few studies linking epidemiology and clinical disease in children. The study objective was to examine the contemporary epidemiology of pediatric toxocariasis within an endemic US region.

METHODS: We conducted an epidemiologic study analyzing children diagnosed with toxocariasis presenting to a tertiary pediatric hospital in Texas from 2010 to 2021. We examined …

The Genetic Associations Of Circadian Rhythm And Sleep Disorder Traits With Risk Of Monoclonal Gammopathy Of Undetermined Significance And Multiple Myeloma, Brittany Crawford

Theses and Dissertations

Background: Circadian rhythm disruption and sleep have been widely studied for their roles in immunity and cancer development. Evidence for an association of circadian rhythm and sleep traits with multiple myeloma (MM) risk is inconclusive. No studies have investigated these traits in relation to monoclonal gammopathy of undetermined significance (MGUS). Given that MGUS precedes almost all MM cases, investigating sleep and circadian rhythm in relation to both MM and MGUS is necessary. The purpose of this dissertation was to explore the genetic influences of circadian rhythm and sleep traits on the risk of MGUS and MM. Methods: Data were leveraged …

The kidneys operate at the interface of plasma and urine by clearing molecular waste products while retaining valuable solutes. Genetic studies of paired plasma and urine metabolomes may identify underlying processes. We conducted genome-wide studies of 1,916 plasma and urine metabolites and detected 1,299 significant associations. Associations with 40% of implicated metabolites would have been missed by studying plasma alone. We detected urine-specific findings that provide information about metabolite reabsorption in the kidney, such as aquaporin (AQP)-7-mediated glycerol transport, and different metabolomic footprints of kidney-expressed proteins in plasma and urine that are consistent with their localization and function, including the …
