Understanding The Syphilis Resurgence Among Females Of Childbearing Age: Informing Prevention Efforts In New York State, Salvatore Currenti

Electronic Theses & Dissertations (2024 - present)

Syphilis is caused by Treponema pallidum and transmitted through direct contact with infected mucosal lesions and via vertical transmission during pregnancy (i.e., congenital). Transmission of syphilis to an infant during pregnancy (i.e., congenital syphilis [CS]) can lead to early fetal death, stillbirth, neonatal death, preterm birth, low birthweight, and congenital infection in infants. The United States (U.S.) is experiencing epidemic increases in both females of reproductive age with syphilis and infants with CS. In New York State (NYS), these trends have also occurred, especially after COVID-19 emergence, and increases in reported cases and incidence rates are comparable to national statistics. …

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 …

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 …

Journal Articles: Epidemiology

INTRODUCTION: To develop interventions to reduce neighborhood-level disparities in pediatric cancer outcomes, it is necessary to understand their underlying mechanisms. It has been suggested that individual-level health insurance is a mediator of neighborhood deprivation and pediatric cancer survival.

METHODS: This study was a population-based longitudinal study of children with cancer from 2000 to 2020 in the Iowa Cancer Registry and Louisiana Tumor Registry. Neighborhood deprivation was measured using the Area Deprivation Index. Log-binomial regression models were used to identify predictors of health insurance status at diagnosis. Cox regression models were used to assess the association between health insurance status at …

Climate And Other Environmental Factors Predict Tick Abundance And Lyme Cases In Minnesota One And Two Years In Advance, Kathleen E. Angell, Janet Jarnefeld, Elizabeth K. Schiffman, M. Jana Broadhurst, Jianghu James Dong, Abraham Degarege, Roberto Cortinas, David Brett-Major

Journal Articles: Epidemiology

BACKGROUND: Environmental factors, like weather and host abundance influence tick populations which in turn affect tickborne disease in endemic regions. It is important to understand how these factors are associated with tick abundance, and whether they can predict disease. We assessed associations between environmental factors, tick abundance, and human Lyme disease cases in the same year and with one- and two-year lags in Minnesota. In parallel, we compare conventional analytical methods with a novel machine learning approach to evaluate their relative strengths and potential for integration.

METHODS: Environmental and tick abundance relationships were examined using generalized linear mixed-effects models (GLMM), …

When Clades Collide: Genomic Admixture In Blacklegged Ticks (Ixodes Scapularis) From The Great Plains, Kaylee S. Herzog, Zach Pella, Halie Smith, Dayna Mccormick, Lily Nuss, Amanda Brinkworth, Sujata S. Chaudhari, Kathryn Duncan, Kellee Sundstrom, Sydney Stein, Holly Black, Jose E. Pietri, Ryan C. Smith, Jeff Hamik, Roberto Cortiñas, Joseph R. Fauver

Journal Articles: Epidemiology

Ixodes scapularis ticks transmit a number of pathogens important to human health, including Borrelia burgdorferi sensu stricto, the causative agent of Lyme disease. While I. scapularis is found across the Eastern United States, Lyme disease transmission is largely limited to the Northeast and Upper Midwest and is nearly absent in the South. This indicates that differences in northern versus southern clades of I. scapularis are associated with differences in Lyme disease transmission risk. Ixodes scapularis is undergoing range expansion, including into the Great Plains region of the United States. Determining where I. scapularis populations in the Great Plains originated can …

Prevalence Of Grip And Leg Strength Asymmetries In U.S. Youth, Elyse M. Deschryver

Theses and Dissertations

Early-life physical activity is important for building muscular strength, supporting healthy growth and disease prevention, and for establishing physical activity and strength habits that often track into adulthood. Although grip strength asymmetry is a well-documented risk factor in older adults, evidence in children and adolescents is limited and largely based on small, sport-specific samples. PURPOSE: To describe grip and leg extension strength asymmetries in a nationally representative sample of U.S. youth aged 6–15 years using the National Youth Fitness Survey (NNYFS). METHODS: The analysis included 1,214 participants (606 boys, 608 girls) with valid grip or leg extension data. Age, sex, …

Vaccination elicits systemic immune responses that extend beyond antibody and lymphocyte activation, engaging coordinated metabolic and lipid pathways that modulate immune function. Nevertheless, how systemic molecular responses differ across COVID-19 vaccine platforms, including closely related mRNA platforms, remains poorly understood. Here, we performed integrated plasma proteomic, lipidomic, and metabolomic profiling of 53 SARS-CoV-2–naïve adults vaccinated with Pfizer-BioNTech, Moderna, or AstraZeneca COVID-19 vaccines. Samples were analysed across multiple timepoints using differential analysis and DIABLO-based multi-omics integration. Our findings reveal distinct platform-associated multi-omic molecular signatures not captured by unsupervised analyses alone. Pfizer-BioNTech vaccination was associated with widespread increases in immunoglobulin and complement …
