Birth Setting Related Outcomes Among Low-Risk, Midwife-Attended Births in Washington State

Community births attended by midwives have gained attention for their potential to support physiologic childbirth and reduce medical interventions compared to hospital births. However, outcomes comparing midwife-attended births following low-risk pregnancies in community and hospital settings remain understudied. Among midwife-attended births, we examined overall and parity-specific associations of birth setting with physiologic birth and hospital…

Investigating the influence of virus-virus interactions on susceptibility to subsequent infections

The co-circulation of multiple respiratory pathogens can lead to competitive or cooperative forms of pathogen–pathogen interactions through broad-acting innate or adaptive immunity leading to enhanced or reduced risk of subsequent infections. Methods: We retrospectively analyzed 6,396 unique individuals from the Seattle Flu Study to investigate viral interference among six respiratory pathogens. Using longitudinal data collected…


Modification of Firearm Law-Firearm Injury Association by Economic Disadvantage

To assess whether the association between firearm law restrictiveness and firearm-related events in the US is modified by community distress and economic connectedness (EC).Methods: National cross-sectional study of firearm incidents (interpersonal and unintentional firearm events) occurring between 1/2015-12/2021 using the Gun Violence Archive (GVA). Exposures were community distress (Distressed Communities Index, DCI), EC, and year-state-level…


Association Between Time of Day of Combination Immune Checkpoint Inhibitor Administration and Overall Survival in Advanced Melanoma Patients

Immune checkpoint inhibitor (ICI) therapy has significantly improved the median overall survival of melanoma patients; however, many patients do not have clinical benefit from ICI therapy. The prognostic role of modifiable factors, such as the time of ICI administration, in immunotherapy treatment outcomes has not been well examined. Recent studies suggest that administration of ICIs…


Characterizing Sociodemographic, Behavioral Correlates, and Trends of Non-binary/genderqueer Patients at Public Health Seattle and King County Sexual Health Clinic

We sought to characterize sociodemographic behaviors and STI outcomes for NB/GQ patients attending the Sexual Health Clinic (SHC) and examine how gender identity among SHC patients has evolved over time. Methods: We used Public Health Seattle-King County (PHSKC) SHC data from 2016-2023…
