Development of a University-Government Partnership for Public Health Response and Workforce Development in the State of Oregon.

The COVID-19 pandemic exposed and exacerbated a public health workforce shortage and national strategies have called for the development of clear occupational pathways for students to enter the public health workforce and meaningful public health careers. In response to the immediate need for public health workers during the pandemic, several universities and academic hospitals rapidly mobilized students and employees and partnered with local or state health departments. However, many of those partnerships were based on short-term volunteer effort to support critical COVID-19 public health efforts. In this article, we document the development of Oregon's Public Health Practice Team, a student, staff, and faculty workforce developed at the Oregon Health & Science University-Portland State University (OHSU-PSU) School of Public Health in close collaboration with the Oregon Health Authority (OHA). This project contributed significant effort to several phases of Oregon's statewide public health response to COVID-19, and over time developed into a lasting, multi-purpose, inter-agency collaborative public health practice program. Health equity has been centered at every stage of this work. We describe the phases of the partnership development, the current team structure and operations, and highlight key challenges and lessons learned. This provides a case-study of how an innovative and flexible university-government partnership can contribute to immediate pandemic response needs, and also support ongoing public health responses to emerging needs, while contributing to the development of a skilled and diverse public health workforce.

Severe Perineal Lacerations in First Delivery: Association with Subsequent Reproductive Outcomes.

Background: Severe perineal lacerations (SPLs), common worldwide, are associated with short- and long-term complications: pelvic floor disorders, fecal incontinence, fistula, and profound psychological impacts. Limited research suggests that experiencing SPL may influence future reproductive intentions, but research on outcomes is lacking. Methods: We analyzed the effect of experiencing SPL during a first delivery among a large cohort of Swedish births between 1992 and 2013. We used linear and multinomial logistic regression to estimate the associations between SPL and four reproductive outcomes: subsequent total birth number, probability of a second birth, interpregnancy interval (IPI), and subsequent scheduled cesarean birth. Results: Among 947,035 singleton live-born first-births, we found that experiencing SPL was associated with slightly fewer overall births in fully adjusted models (a decrease of -0.020 births; 95% confidence interval [CI]: -0.028 to -0.012), but no difference in the probability of a second birth (risk ratio [RR]: 1.00; 95% CI: 0.99 to 1.00) or IPI. Scheduled cesarean was increased in births after SPL (adjusted RR: 4.57; 95% CI: 4.42 to 4.73). A secondary comparison of SPL to severe postpartum hemorrhage suggests that some of these observed differences may be related to experiencing any severe outcome, and some specifically to perineum disruption. Conclusion: This study provides a deeper understanding of the long-term impacts of SPL, which may be useful in informing best clinical practices for supporting women who have experienced SPL.

Pre-Pregnancy Health Risks by Presence and Extent of Disability, 2019-2020.

INTRODUCTION: Prior studies have shown that, compared to non-disabled women, women with disabilities have a higher burden of preconception mental and physical health risks that are associated with adverse pregnancy outcomes. This cross-sectional study assesses how the extent of disability relates to pre-pregnancy health risks. METHODS: This study used 2019-2020 PRAMS data from 22 sites that included the Washington Group Short Set of Questions on Disability (n=37,006). In 2023, associations between extent of disability (none [reference group], some difficulty, or a lot of difficulty) and preconception health risks were examined using multivariable Poisson regression with robust standard errors to calculate adjusted prevalence ratios (aPRs) and 95% CIs while controlling for sociodemographic characteristics. Preconception health risks included smoking, heavy drinking, high blood pressure, diabetes, no multivitamin use, and experiencing physical abuse, depression, or obesity. Individual risks were analyzed, as well as the total number of risks experienced. RESULTS: Of respondents, 33.6% had some difficulty and 6.3% had a lot of difficulty. The likelihood of experiencing preconception health risks increased with extent of disability. Compared to respondents with no difficulty, those with some or a lot of difficulty had a higher prevalence of experiencing 1-2 health risks (aPR=1.13, 95% CI 1.09, 1.18; aPR=1.20; 95% CI 1.53, 2.25) and 3+ health risks (aPR=1.86, 95% CI 1.53, 2.25; aPR=2.42, 95% CI 1.98, 2.97), respectively. CONCLUSIONS: Disabled women, especially those with more difficulty, are vulnerable to preconception health risks that could potentially be mitigated before conception. These findings highlight the need for enhanced efforts to support preconception health of disabled women.

Replication and validation of a statewide linkage method to estimate incidence proportion of child maltreatment.

PURPOSE: To study familial factors associated with child maltreatment in a birth population, Alaska piloted a mixed-design method that linked child welfare data with the Pregnancy Risk Assessment Monitoring System (PRAMS). We replicated this approach in Oregon and validated it in both states. METHODS: We linked vital records, child welfare, and PRAMS data to create two 2009 birth cohorts for each state: one based on vital records (full birth cohort) and one on PRAMS (stratified random sample). For each cohort, we estimated the incidence proportions (IP) of child maltreatment before age 9 years and compared those estimated using PRAMS with those observed using the full birth cohort. RESULTS: The Oregon PRAMS cohort estimated that 28.7% (95% CI: 24.0, 33.4), 20.9% (17.1, 24.7), and 8.3% (6.0, 10.5) of children experienced an alleged, investigated, and substantiated maltreatment, respectively, versus 32.0%, 25.0%, and 9.9% from the birth cohort. The corresponding Alaska estimates were 29.1% (26.1, 32.0), 22.6% (19.9, 25.2), and 8.3% (6.7, 9.9) of children from the PRAMS cohort versus 29.1%, 23.5%, and 9.1% in the birth cohort. CONCLUSIONS: The IP of child maltreatment in two states was accurately estimated with PRAMS cohorts. Researchers can study a comprehensive set of factors that may influence child maltreatment by incorporating PRAMS into birth cohort linkages.

Healthy and Respectful Relationship Education: Differences by Disability Status and Associations With Sexual Abuse.

BACKGROUND: Education about healthy and respectful relationships (HRR) is a key component of comprehensive sexual health curricula and is supposed to be universally provided in Oregon. This study: (1) assesses the extent to which high school students with disabilities received HRR education, and (2) examines associations between HRR education and experiences of sexual abuse. METHODS: Using data from the 2019 Oregon Healthy Teens survey, we conducted multivariable Poisson regression to compare 11th grade students with and without disabilities on self-reported receipt of school based HRR instruction (N = 10,992), and to measure associations between HRR education and sexual abuse experiences among teens with (N = 3736) and without (N = 7256) disabilities. RESULTS: Students with disabilities were 41% more likely than students without disabilities to say they had never been taught in school about HRR (adjusted prevalence ratio 1.41, 95% confidence interval: 1.25-156). Experiences of sexual abuse victimization were more common for all students who did not receive HRR education (34.1% vs 21.6% among students with disabilities; 16.2% vs 7.5% among students without disabilities). CONCLUSIONS: Students with disabilities are less likely to have received school-based HRR education than their peers without disabilities. Providing inclusive HRR education may help reduce risk of sexual abuse and is essential for addressing health disparities affecting youth with disabilities.

Maternal Intimate Partner Violence Victimization Before and During Pregnancy and Postbirth Child Welfare Contact: A Population-Based Assessment.

We conducted a population-based prospective cohort study to help elucidate the predictive relationship between a maternal prebirth self-reported history of intimate partner violence (IPV) and any postbirth reported allegation to Child Protective Services (CPS) by age 2. We linked data from the 2009-2010 Alaska Pregnancy Risk Assessment Monitoring System with CPS data through 2012. Among this cohort, we found that 8.0%w self-reported experiencing IPV 12 months prior or during pregnancy, and 8.0%w of the offspring experienced at least one CPS report of alleged maltreatment during the study period. The predictive relationship varied by maternal educational attainment. Among mothers with 12+ years education completed, the odds of a CPS report were 3.9 times compared to those with no IPV, while among mothers with <12 years education completed, no association was noted. These results suggest that for a subset of Alaskan families, maternal history of IPV is a strong independent predictor of future CPS contact.

Characterization of lower molecular weight artifact bands of recombinant monoclonal IgG1 antibodies on non-reducing SDS-PAGE.

SDS-PAGE under non-reducing conditions is one of the most commonly used techniques for recombinant monoclonal antibody purity and stability indicating assay. On non-reducing SDS-PAGE, bands with a lower molecular weight than the intact antibody are routinely observed and is a common feature of IgG molecules. These fragments were analyzed by in-gel digestion followed by matrix-assisted-laser-desorption-ionization time-of-flight (MALDI-TOF) mass spectrometry, Western blot and by comparing the banding pattern of sample prepared in the presence of a reducing reagent. The fragments bands were identified as antibody lacking one light chain, two heavy chains, one light chain and one heavy chain, free heavy chain and free light chain. Sensitivity of fragmentation to sample buffer pH, incubation time, reducing reagent and alkylation reagents indicated that fragments were formed during sample preparation, but not present in the samples analyzed. Disulfide bond scrambling and beta-elimination are the two major mechanisms of the formation antibody fragments. Mass spectrometry analysis suggested that disulfide bond scrambling can be prevented by specifically modifying free sulhydryl using alkylation and thus reduced the amount of artifacts on non-reducing SDS-PAGE. Breakage of disulfide bonds by beta-elimination was evidenced by the detection of dehydroalanine using mass spectrometry.
