Associations Between Neighborhood Physical And Social Stressors During Sensitive Developmental Periods And Substance Use In Early Adulthood, Abigail M. Ulofoshio Jan 2026

Associations Between Neighborhood Physical And Social Stressors During Sensitive Developmental Periods And Substance Use In Early Adulthood, Abigail M. Ulofoshio

Electronic Theses & Dissertations (2024 - present)

Background

Substance use is a major public health problem. Neighborhood disadvantage and related stressors have been linked to increased substance use in adolescence and early adulthood, although findings are mixed. No studies have explored whether the timing or accumulation of neighborhood stressors in childhood and adolescence impact substance use in early adulthood. This study aims to investigate to what extent physical and social neighborhood stress during sensitive developmental periods influence substance use dependency and illicit substance use in early adulthood.

Methods

We analyzed an imputed sample (n = 7,494) from the Avon Longitudinal Study of Parents and Children (ALSPAC), a …

Assessing And Advancing Pandemic Emergency Preparedness In New York City's Hospitals: A Strategic Management Toolkit Integrating Policy Analysis, Risk Assessment, And Stakeholder Insight, Irrem Jamal

College of Graduate Studies: Theses & Dissertations

This dissertation examines pandemic emergency preparedness in New York City hospitals, which were severely strained during COVID-19, revealing critical gaps between documented plans and operational readiness. Using a multimethod approach combining a survey of 20 stakeholders across city hospitals, semi-structured interviews, and document analysis of policy frameworks and after-action reports, the study identifies a persistent "documentation-execution paradox": while 80% of respondents confirmed clear pandemic plans, only 45% expressed confidence in staffing adequacy, 55% in surge planning realism, and just 45% confirmed regular drills. Qualitative analysis revealed workforce as the single greatest yet most underinvested vulnerability, supply chain fragility rooted in …

Journal Articles: Epidemiology

While humoral responses to vaccination and infection have largely focused on IgG, there is an evolving literature on ways in which IgA may drive neutrophil activity in lung injury secondary to viral infections, including COVID-19. We evaluated 238 immune-naïve, critically ill patients in the first year of the COVID-19 pandemic. Employing a laboratory-developed, multiplexed antibody testing, clinical history, medical record, and machine learning, we pursued relationships between systemic IgA and disease severity. Individuals with elevated anti-N IgA had 4-fold odds of more severe disease. This work emphasizes the importance of continued work to understand how different elements of the immune …

Management-Driven Shifts In The Bison Fecal Microbiome And Its Relationship To Stec Prevalence, Ritesh Ray Jan 2026

Management-Driven Shifts In The Bison Fecal Microbiome And Its Relationship To Stec Prevalence, Ritesh Ray

Graduate Research Theses & Dissertations

Contamination of meat samples from pathogens such as Shiga toxin-producing E. coli (STEC), especially in ruminants, is an ever-growing issue for the safety of global meat production. Recent studies have reported STEC in the livestock and food industry with a limited focus on wildlife. Although cattle serve as the primary reservoir for STEC, American bison (Bison bison bison) is the largest ruminant inhabiting North America, sharing similar genetics, and grazing habits, making them an ideal alternative STEC reservoir. Re-introduction for prairie conservation and meat farming has brought bison herds closer to anthropic environments than before. Recently bison meat has become …


Rurality, Infant Feeding Practices, And Perinatal Cardiovascular Health Behaviors, Elly Marie Marshall Jan 2026

Rurality, Infant Feeding Practices, And Perinatal Cardiovascular Health Behaviors, Elly Marie Marshall

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: Cardiovascular diseases are a leading cause of pregnancy-related deaths in the United States, with higher rates in rural areas. While limited healthcare access contributes to this disparity, other factors remain unclear. Breastfeeding provides long-term protection against cardiovascular disease, but modern infant feeding practices are complex and may impact maternal cardiovascular health (CVH) in unexpected ways. Healthy CVH behaviors of sufficient sleep duration, adequate physical activity, a healthy diet, and nicotine avoidance can enhance protection against future cardiovascular disease risk. Therefore, the aims of this dissertation are to 1) assess associations between rurality and first trimester CVH behaviors; 2) synthesize …

Seasonal And Geographic Patterns Of Gastroschisis In Canada: Protective Effect Of Periconceptional Sunlight Exposure, Shiliang Liu, Shin Jie Yong, Dunjin Chen, Gavin C. Hughes, Claude L. Hughes

Department of Medicine Faculty Publications

Background: Gastroschisis is a right-sided, full-thickness defect with extra-amnionic herniation of abdominal contents directly into the amniotic cavity. The causes of gastroschisis remain obscure. We hypothesized that limited periconceptional sunlight exposure might lead to insufficient vitamin D during fetal development and play a role in gastroschisis etiology.

Methods: We conducted a population-based cohort study of infants conceived in Canada between April 2006 and March 2020. We used winter months (i.e., November and December) and northern geographic latitudes as indicators of insufficient sunlight exposure, while summer months (July and August) and southern geographic latitudes were considered as reference. We examined the …

Dietary Acculturation, Dietary Inflammatory Potential, And Metabolic Syndrome Among Immigrants In The United States: A Mixed-Methods Approach Using Nhanes And Qualitative Data, Esse G. Foka Nzaha

Theses and Dissertations

Background and Objectives: Immigrants in the United States undergo acculturation — a process of sociocultural and behavioral adaptation to the host country. Increasingly, behavioral adaptations have been associated with cardiometabolic health and chronic disease risk. Metabolic syndrome (MetS), a cluster of conditions including abdominal obesity, elevated blood pressure, impaired fasting glucose, elevated triglycerides, and reduced HDL cholesterol, is a major risk factor for type 2 diabetes mellitus, cardiovascular diseases and other chronic diseases, including cancer. Despite the growing immigrant population in the U.S., the role of diet and dietary acculturation in MetS development remains poorly understood in this population. This …


24-H Circadian Rest-Activity Rhythms And Physical Frailty In Older Adults: A Biopsychosocial Perspective On Sex Differences And Social Capital, Jisu Kim Jan 2026

24-H Circadian Rest-Activity Rhythms And Physical Frailty In Older Adults: A Biopsychosocial Perspective On Sex Differences And Social Capital, Jisu Kim

Theses and Dissertations

Physical frailty is a prevalent geriatric syndrome characterized by age-related decline across multiple physiological systems. Physical frailty is associated with an elevated risk of adverse health outcomes, including chronic disease progression and all-cause mortality, representing a significant and growing public health concern. Disrupted circadian rest-activity rhythms (RARs) are increasingly recognized as clinically meaningful markers of physical frailty in older adults. However, the extent to which biological sex and social determinants of health (SDoH), particularly social capital, contribute to or modify the associations between RARs and physical frailty remains underexplored.

Therefore, this dissertation summarizes the existing literature on age-related changes in …

Department Dermatology Faculty Publications

Psoriasis is associated with an increased risk of major adverse cardiovascular events (MACE), and biologic therapy may reduce this risk by targeting systemic inflammation. However, limited data exist on whether long term MACE risk differs by biologic class or across racial groups. We conducted a retrospective cohort study to assess the risk of primary MACE in psoriasis patients receiving biological therapies, stratified by biological class, compared with biologic-naïve psoriasis patients. Whether MACE risk among biologic-treated patients varied by race was further examined. After 1:1 propensity score matching, 36 330 biologic-treated patients were compared with 36 330 non-biologic-treated patients. Incident MACE …

Access To Appropriate Care, Mortality, And Cost Of Inpatient Hospitalization In Infants With Omphalocele And Gastroschisis In The United States, Treeva A. Jaff

Electronic Theses & Dissertations (2024 - present)

Congenital abdominal wall defects (AWDs), including omphalocele (OM) and gastroschisis (GS), are rare but clinically significant conditions that require immediate surgical intervention and prolonged neonatal intensive care. OM is a midline defect in which abdominal organs protrude into the umbilical cord covered by a membranous sac, while GS is a full-thickness defect typically located to the right of the umbilicus through which organs protrude without protective coverage. OM is frequently associated with major co-occurring congenital anomalies and chromosomal abnormalities, while GS more commonly occurs as an isolated defect but requires more intensive surgical management. As survival rates have improved, research …


Hepatitis C Among Persons Who Inject Drugs In New York State: Progress Towards Elimination, Meredith A. Barranco Jan 2026

Hepatitis C Among Persons Who Inject Drugs In New York State: Progress Towards Elimination, Meredith A. Barranco

Electronic Theses & Dissertations (2024 - present)

Background: Hepatitis C virus (HCV) infection is one of the leading causes of liver disease in the United States (US) and worldwide. In the United States today, HCV is transmitted primarily through injection drug use (IDU) and therefore disproportionately impacts persons who inject drugs (PWID), a population with a range of complex social and health needs. HCV is not vaccine-preventable but can be cured in over 90% of cases with an 8–12-week course of daily direct-acting antiviral (DAA) medication. Since approval of curative medications in 2014, various jurisdictions have developed plans to eliminate HCV. In 2021, the New York State …
