Characterizing the climate risks, social vulnerability, and neonatal transport burden on neonatal intensive care units in the United States under 2°C and 50cm sea level rise

Abstract IntroductionThe impacts of climate change are becoming more significant, leading to more extreme weather events across the United States, including extreme temperatures, flooding, and wildfires. Climate disasters can threaten healthcare access and induce hospital shut-downs, forcing relocation of patients, with the potential for serious health consequences for vulnerable populations like neonates in neonatal intensive…


Association Between Social Connection and Gender Identity Among Transgender and Gender-Diverse Veterans

Abstract BackgroundSocial connection plays an important health buffering role in the wellbeing of transgender and gender-diverse (TGD) people. It is not well understood whether social connection differs between binary (transgender men and women) and nonbinary (individuals who do not identity as men or women) TGD individuals. This study compared social connection among binary transgender and…


Exploring the Intersection Between Persistent Poverty and Rurality Status for Advanced Stage Diagnosis of Breast Cancer using the Surveillance, Epidemiology, and End Results (SEER) Program

Abstract Persistent poverty has been associated with disparities in cancer outcomes. Prior studies have described these disparities as most important for rural areas. This study seeks to provide insight into the roles of persistent poverty and rurality status, on receiving an advanced stage breast cancer diagnosis (stage II, III, and IV) relative to stage I….


Association of Medicaid Status with Patient Mental Health Diagnosis: Data from the WA State Perinatal Psychiatry Consultation Line

Abstract Background: Despite Medicaid’s critical role in covering perinatal and behavioral health care costs, many enrollees face barriers to timely mental health diagnosis and treatment. Understanding how insurance shapes access to mental health services and how this intersects with race and ethnicity is critical in addressing inequities in perinatal mental health care. The relationship between…


The severity and correlates of dysmenorrhea among women in Western Kenya

Abstract Dysmenorrhea is the most common menstrual disorder, bearing the highest disease burden of any gynecological issue in low- and middle-income countries. There is a lack of data on the frequency, severity, and correlates of dysmenorrhea among women in Kenya. This thesis utilized cross-sectional data from the n=277 women enrolled in the PrIMA-X study in…


Has the use of a digital hand hygiene monitoring tool been associated with a decreased prevalence of hospital acquired infections in Siem Reap Provincial Referral Hospital?

Abstract The practice of hand hygiene (HH) is a key intervention to decrease the rate of healthcare associated infections (HCAI). We performed a pre-post analysis to assess the association between the use of a digital monitoring tool for hand hygiene compliance and the prevalence of HCAI in the Siem Reap Provincial Referral hospital in Cambodia….


Disparities in Adverse Environmental Chemical Exposures among Women and their Association with Spontaneous Preterm Birth: NHANES 2015-2016 and CHAMACOS Cohorts

Abstract Background: Exposures to adverse environmental chemicals have been related to numerous adverse health outcomes including preterm birth (PTB). Populations who are disproportionately exposed to these adverse chemical exposures have not been fully described. Further, chemical risk factors for spontaneous preterm birth (sPTB), the most common subtype, remain insufficiently characterized. Methods: We used data from…


Associations of Serum Neurofilament Light Chain Concentration with Able Life and Healthy Life in Older Adults: The Cardiovascular Health Study

Abstract Serum neurofilament light chain (NfL) is a sensitive biomarker of brain injury, which has been increasingly used to prognosticate and monitor disease activity and treatment response in neurological diseases. Neural injury impacts the ability to live independently and maintain long-term health. These analyses aimed to examine the association of serum NfL concentrations with able…


Disordered Eating Behavior, Diabetes-Related Distress, and HbA1c among Adolescents and Young Adults with Type 1 Diabetes

Abstract Background: Adolescents and young adults (AYA) with type 1 diabetes (T1D) face elevated risk for poor glycemic control due to both psychosocial and social determinants related factors. Disordered eating behaviors (DEBs) and diabetes distress (DD) are two key psychosocial factors linked to worse outcomes. While DEBs and DD are well-documented contributors to poor glycemic…


Epidemiology of Symptomatic Respiratory Viral Codetections Among Children and Adults in the Cascadia Community-Based Cohort, 2022-2024

Abstract Background: Respiratory virus codetection, or the concurrent presence of multiple viruses in a single host, can complicate diagnoses and may influence clinical severity. This study examined the burden and clinical impact of viral codetections in a community-based U.S. cohort, focusing on eight common respiratory pathogens, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), influenza…
