Predicting Efficacy of a Purified Inactivated Zika Virus Vaccine in Flavivirus-Naïve Humans Using an Immunological Correlate of Protection in Non-Human Primates.

A traditional phase 3 clinical efficacy study for a Zika vaccine may be unfeasible because of the current low transmission of Zika virus (ZIKV). An alternative clinical development approach to evaluate Zika vaccine efficacy (VE) is therefore required, delineated in the US FDA's Accelerated Approval Program for licensure, which utilizes an anti-Zika neutralizing antibody (Zika NAb) titer correlated with non-human primate (NHP) protection as a surrogate endpoint. In this accelerated approval approach, the estimation of VE would be inferred from the percentage of phase 3 trial participants achieving the established surrogate endpoint. We provide a statistical framework to predict the probability of protection for human participants vaccinated with a purified inactivated ZIKV vaccine (TAK-426), in the absence of VE measurements, using NHP data under a single-correlate model. Based on a logistic regression (LR) with bias-reduction model, a probability of 90% protection in humans is expected with a ZIKV NAb geometric mean titer (GMT) ≥ 3.38 log10 half-maximal effective concentration (EC50). The predicted probability of protection of TAK-426 against ZIKV infection was determined using the two-parameter LR model that fit the calculated VE in rhesus macaques and the flavivirus-naïve phase 1 trial participants' ZIKV NAb GMTs log10 EC50, measured by a ZIKV reporter virus particle assay, at 1 month post dose 2. The TAK-426 10 µg dose predicted a probability of protection from infection of 98% among flavivirus-naïve phase 1 trial participants.

Endometrial Thickness as Diagnostic Triage for Endometrial Cancer Among Black Individuals.

Importance: Poor performance of the transvaginal ultrasonography triage strategy has been suggested as a contributor to racial disparity between Black individuals and White individuals in endometrial cancer (EC) stage at diagnosis in population-level simulation analyses. Objectives: To examine the false-negative probability using ultrasonography-measured endometrial thickness (ET) thresholds as triage for EC diagnosis among Black individuals and assess whether known risk factors of EC modify ET triage performance. Design, Setting, and Participants: This retrospective diagnostic study of merged abstracted electronic health record data and secondary administrative data (January 1, 2014, to December 31, 2020) from the Guidelines for Transvaginal Ultrasound in the Detection of Early Endometrial Cancer sample assessed Black individuals who underwent hysterectomy in a 10-hospital academic-affiliated health care system and affiliated outpatient practices. Data analysis was performed from January 31, 2023, to November 30, 2023. Exposure: Pelvic ultrasonography within 24 months before hysterectomy. Main Outcome and Measures: Ultrasonography performed before hysterectomy as well as demographic and clinical data on symptom presentation, endometrial characterization, and final EC diagnosis were abstracted. Endometrial thickness thresholds were examined for accuracy in ruling out EC diagnosis by using sensitivity, specificity, and negative predictive value. False-negative probability was defined as 1 - sensitivity. Accuracy measures were stratified by risk factors for EC and by factors hypothesized to influence ET measurement quality. Results: A total of 1494 individuals with a uterus (median [IQR] age, 46.1 [41.1-54.0] years) comprised the sample, and 210 had EC. Fibroids (1167 [78.1%]), vaginal bleeding (1067 [71.4%]), and pelvic pain (857 [57.4%]) were the most common presenting diagnoses within 30 days of ultrasonography. Applying the less than 5-mm ET threshold, there was an 11.4% probability that someone with EC would be classified as not having EC (n = 24). At the 4-mm (cumulative) threshold, the probability was 9.5%, and at 3 mm, it was 3.8%. False-negative probability at the 5-mm threshold was similar among EC risk factor groups: postmenopausal bleeding (12.4%; 95% CI, 7.8%-18.5%), body mass index greater than 40 (9.3%; 95% CI, 3.1%-20.3%); and age 50 years or older (12.8%; 95% CI, 8.4%-18.5%). False-negative probability was also similar among those with fibroids on ultrasonography (11.8%; 95% CI, 6.9%-18.4%) but higher in the setting of reported partial ET visibility (26.1%; 95% CI, 10.2%-48.4%) and pelvic pain (14.5%; 95% CI, 7.7%-23.9%). Conclusion and Relevance: These findings suggest that the transvaginal ultrasonography triage strategy is not reliable among Black adults at risk for EC. In the presence of postmenopausal bleeding, tissue sampling is strongly recommended.

Appropriateness of Hysterectomy as Treatment for Benign Gynecological Conditions.

Objective: To assess the appropriateness of hysterectomies performed at a large tertiary health system using the 1997 RAND appropriateness classification system and an updated algorithm. Design: We abstracted structured and unstructured data from electronic medical records on patient demographics, primary indication(s) for hysterectomy, diagnosis codes associated with the hysterectomy, previous treatments, and laboratory results. Subjects: Patients aged 18-44 years. Exposure: Receipt of hysterectomy for benign and nonobstetric conditions from October 2014 to December 2017. Main Outcome Measures: Using these data, we provided a RAND-based (dichotomous: inappropriate/appropriate) and Wright-based (3-level: inappropriate/ambiguous/appropriate) appropriateness rating and characterized missing information patterns associated with inappropriate ratings. Results: We analyzed 1,829 hysterectomies across 30 nonmutually exclusive primary indications for surgery. Nearly a third (32.8%) of surgeries had only one primary indication for surgery. Using the RAND-based classifier, 31.3% of hysterectomies were rated as appropriate and 68.7% as inappropriate. Using the Wright-based algorithm, 58.1% of hysterectomies were rated as appropriate, 15.7% as ambiguous, and 26.2% as inappropriate. Missing information on diagnostic procedures was the most common characteristic related to both RAND-based (46.1%) and Wright-based (51.2%) inappropriate ratings. Conclusions: The 1997 RAND classification lacked guidance for several contemporary indications, including gender-affirming care. RAND also has an outdated requirement for diagnostic surgeries such as laparoscopies, which have decreased in practice as diagnostic imaging has improved. Sensitivity analyses suggest that inappropriate surgeries cannot all be attributed to bias from missing electronic medical record data. Accurately documenting care delivery for benign gynecological conditions is key to ensuring quality and equity in gynecological care.

Oxytocin versus oral misoprostol for PROM induction in nulliparas with unfavorable cervix: A randomized trial.

BACKGROUND: Induction of labor (IOL) is recommended following prelabor rupture of membranes (PROM). The optimal method for IOL and need for cervical ripening in those with PROM and an unfavorable cervical examination is unclear. OBJECTIVE: To determine if oxytocin or oral misoprostol results in a shorter time to delivery among nulliparous patients with an unfavorable cervical examination and PROM diagnosis and to evaluate patient satisfaction with both methods. STUDY DESIGN: This is a randomized clinical trial conducted at an urban tertiary care center from 2019-2023. Subjects were nulliparas ≥ 36 weeks with an unfavorable starting cervical exam (≤ 2 cm and Bishop < 8). The primary outcome was time from IOL to delivery in hours compared between oxytocin versus oral misoprostol. Secondary outcomes included suspected intraamniotic infection, cesarean delivery, composite maternal and neonatal morbidity, and patient satisfaction (assessed by Birth Satisfaction Scale-Revised (BSS-R)). Sub-group analyses for those with BMI ≥ 30kg/m2 and cervical dilation ≥ 1cm were performed. We required 148 subjects to have 80% power to detect a 2-hour difference in time to delivery. The study was stopped early by the DSMB due to feasibility concerns in recruiting desired sample size Results: 108 subjects were randomized: 56 oxytocin; 52 oral miso. The median gestational age at induction was 39.5 weeks; the mean starting cervical dilation was 1.1 cm. There was no statistical difference in time to delivery between groups overall: 14.9 hours oxytocin v. 18.1 hours oral misoprostol (p=0.06). In sub-group analyses, there was a 5h shorter time to delivery with oxytocin for those with a BMI ≥ 30kg/m2 (16.6 hours oxytocin v. 21.8 hours oral misoprostol, p 0.04) and 4.5h shorter time to delivery with oxytocin for those with cervix ≥ 1cm (12.9 hours oxytocin v. 17.3 hours oral misoprostol, p 0.04). There were no differences in intraamniotic infection, cesarean delivery, maternal or neonatal morbidity between the groups. Patient satisfaction was higher for those receiving oxytocin compared to misoprostol (29.0 vs. 26.3, p=0.03). CONCLUSIONS: Among nulliparas with PROM and an unfavorable cervix, there was no difference in overall time to delivery between oxytocin and oral misoprostol. This result should be interpreted with caution given early study discontinuation and inadequate power. However, a shorter time to delivery with oxytocin was noted in obese patients and those with cervical dilation of at least 1 cm. Furthermore, patient satisfaction was higher in the oxytocin group, and there was no increased risk of neonatal or maternal morbidity with oxytocin.

Characterizing Stress Processes by Linking Big Five Personality States, Traits, and Day-to-Day Stressors.

The accumulation of day-to-day stressors can impact mental and physical health. How people respond to stressful events is a key mechanism responsible for the effects of stress, and individual differences in stress responses can either perpetuate or prevent negative consequences. Most research on daily stress processes has focused on affective responses to stressors, but stress responses can involve more than just affect (e.g., behavior, cognitions). Additionally, most research has studied the role of neuroticism in shaping those responses, but many other individual differences are associated with stress. In this study, we more broadly characterized daily stress processes by expanding the nomological networks of stress responses to include Big Five personality states. We also linked those stress responses to all Big Five traits, as well as individual differences in stress variety, severity, and controllability. We studied a sample of participants (N = 1,090) who reported on stressful events, their appraisal of events in terms of severity and controllability, and their Big Five personality states daily for 8-10 days (N = 8,870 observations). Multi-level structural equation models were used to separate how characteristics of the perceived stressful situation and characteristics of the person play into daily stress processes. Results showed that (1) all Big Five personality states shift in response to perceived stress, (2) all Big Five personality traits relate to average levels of perceived stress variety, severity, and controllability, (3) individual differences in personality and average perceived stress variety and perceived severity relate to the strength of personality state responses to daily stress, albeit in a more limited fashion. Our results point to new pathways by which stressors affect people in everyday life and begin to clarify processes that may explain individual differences in risk or resilience to the harmful effects of stress.

Comparing the Diagnostic and Statistical Manual of Mental Disorders, fifth edition, personality disorder models scored from the same interview.

The alternative model of personality disorders (AMPD) traits were designed to maintain continuity with the Section II personality disorder (PD) diagnoses by retaining the same clinical information. Whether the AMPD traits achieve this is not well established. Prior work testing incremental validity of AMPD traits and Section II diagnoses is limited by the fact each model was measured by a different instrument or rater, making it unclear whether discrepancies are due to the constructs or methods. Here, we compare the incremental validity of AMPD traits versus Section II PDs assessed by the same instrument and rater. Participants (N = 311, 50% received past-year mental health treatment) completed a clinical interview, baseline self-reports, and 14-day ambulatory assessment protocol. Interviewers rated AMPD domains, facets, and Section II criteria from the same interview (Structured Interview for DSM-IV Personality). We used hierarchical regression models to evaluate the variance predicted in 17 clinically relevant cross-sectional and momentary variables by the AMPD traits and Section II PDs. Incremental R² showed that Section II PDs account for little variance in outcomes over and above the AMPD domains/facets, whereas the AMPD facets were generally more predictive of outcomes than the Section II PDs. Results add novel evidence that dimensional PD traits-not a particular assessment method-are equivalent or superior to PD categories for predicting social, emotional, and behavioral functioning.

Cross-situational variability in childhood personality states.

Personality variability is an important individual difference construct that is the focus of major psychological theories and relates to socioemotional functioning. Although cross-situational personality variability has been studied extensively in adult populations, little is known about variability in children's personality. In this study, we aimed to address this gap in knowledge by evaluating whether cross-situational variability is a potentially meaningful individual difference in youth. We used a "thin slice" approach in which research assistants viewed videos of 324 children (Mage = 9.92) completing 15 standardized tasks and rated youth's Big Five personality states. Cross-situational variability in each personality state was estimated by calculating within-person standard deviations across tasks. Results showed that (a) there is substantial variability in children's personality states; (b) children who are variable in one personality domain tend to be variable in other domains; and (c) more variable children are described by their parents as being less competent, less agreeable, less conscientious, and more neurotic. However, associations with parent-rated external criterion were generally small in magnitude, and key psychometric properties of the thin slice personality variability index are not well-established. Our study adds tentative but promising evidence that individual differences in cross-situational personality variability are not only present in childhood but may be consequential.

Real-world Effectiveness of mRNA COVID-19 Vaccines Among US Nursing Home Residents Aged ≥65 Years in the Pre-Delta and High Delta Periods.

Background: Long-term care residents were among the most vulnerable during the COVID-19 pandemic. We estimated vaccine effectiveness of mRNA COVID-19 vaccines in Medicare nursing home residents aged ≥65 years during pre-Delta and high Delta periods. Methods: We conducted a retrospective cohort study from 13 December 2020 to 20 November 2021 using Medicare claims data. Exposures included 2 and 3 doses of Pfizer-BioNTech and Moderna COVID-19 vaccines. We used inverse probability weighting and Cox proportional hazards models to estimate absolute and relative vaccine effectiveness. Results: Two-dose vaccine effectiveness against COVID-19-related death was 69.8% (95% CI, 65.9%‒73.3%) during the pre-Delta period and 55.7% (49.5%‒61.1%) during the high Delta period, without adjusting for time since vaccination. We observed substantial waning of effectiveness from 65.1% (54.2%‒73.5%) within 6 months from second-dose vaccination to 45.2% (30.6%‒56.7%) ≥6 months after second-dose vaccination in the high Delta period. Three doses provided 88.7% (73.5%‒95.2%) vaccine effectiveness against death, and the incremental benefit of 3 vs 2 doses was 74.6% (40.4%‒89.2%) during high Delta. Among beneficiaries with a prior COVID-19 infection, 3-dose vaccine effectiveness for preventing death was 78.6% (50.0%‒90.8%), and the additional protection of 3 vs 2 doses was 70.0% (30.1%‒87.1%) during high Delta. Vaccine effectiveness estimates against less severe outcomes (eg, infection) were lower. Conclusions: This nationwide real-world study demonstrated that mRNA COVID-19 vaccines provided substantial protection against COVID-19-related death. Two-dose protection waned after 6 months. Third doses during the high Delta period provided significant additional protection for individuals with or without a prior COVID-19 infection.

Adolescent Healthcare Access: A Qualitative Study of Provider Perspectives.

INTRODUCTION: Adolescent access to quality healthcare is key to prevention and early intervention for health risk behaviors. This paper provides a healthcare provider perspective on barriers and facilitators to youth accessing care. METHODS: Five focus groups were conducted from November to December 2020 with providers from a variety of healthcare settings. Participants were asked to describe their respective adolescent patient populations, adolescent-specific health concerns, and organizational accommodations specific for youth services. Transcripts were analyzed using Inductive Thematic Analysis and themes were grouped using a social-ecological framework. RESULTS: At an individual level, providers noted that an adolescent's knowledge and ability to navigate services varied greatly across settings. Providers identified provider trust and parent/guardian support as key interpersonal factors that support adolescents' access to services. Organizational factors included bureaucratic barriers and the clinic's reputation among youth. Community factors centered on mistrust within healthcare systems and stigmatization of seeking certain types of services. Participants also described how state-level policies influence parent/guardian consent requirements, which can limit adolescents' access to care. CONCLUSION: Adolescent access to and utilization of healthcare in the United States is a complex problem requiring systems-level change. Healthcare organizations and providers have the opportunity and capacity to positively influence adolescents' healthcare access and experiences, however a lack of standardized, clinic-level priorities and guidelines can limit adolescent-centered care.

ROR2/Wnt5a Signaling Regulates Directional Cell Migration and Early Tumor Cell Invasion in Ovarian Cancer.

Adhesion to and clearance of the mesothelial monolayer are key early events in metastatic seeding of ovarian cancer. ROR2 is a receptor tyrosine kinase that interacts with Wnt5a ligand to activate noncanonical Wnt signaling and has been previously shown to be upregulated in ovarian cancer tissue. However, no prior study has evaluated the mechanistic role of ROR2 in ovarian cancer. Through a cellular high-throughput genetic screen, we independently identified ROR2 as a driver of ovarian tumor cell adhesion and invasion. ROR2 expression in ovarian tumor cells serves to drive directed cell migration preferentially toward areas of high Wnt5a ligand, such as the mesothelial lined omentum. In addition, ROR2 promotes ovarian tumor cell adhesion and clearance of a mesothelial monolayer. Depletion of ROR2, in tumor cells, reduces metastatic tumor burden in a syngeneic model of ovarian cancer. These findings support the role of ROR2 in ovarian tumor cells as a critical factor contributing to the early steps of metastasis. Therapeutic targeting of the ROR2/Wnt5a signaling axis could provide a means of improving treatment for patients with advanced ovarian cancer. IMPLICATIONS: This study demonstrates that ROR2 in ovarian cancer cells is important for directed migration to the metastatic niche and provides a potential signaling axis of interest for therapeutic targeting in ovarian cancer.

Endometriosis and Disability: Analysis of Federal Court Appeals of Social Security Disability Insurance and Supplemental Security Income Claims by Individuals Suffering From Endometriosis.

BACKGROUND: Endometriosis, a chronic noncancerous gynecologic condition commonly characterized by disruptive physical and psychosocial symptoms, can be disabling. Individuals in the United States with endometriosis who are unable to work before retirement age can apply for Social Security Disability Insurance (SSDI) and/or Supplemental Security Income (SSI). Given the multi-step process of disability review, it is important to better understand how disability decisions are made. This study aimed to examine approaches and rationales of U.S. federal appeals courts reviewing SSDI and/or SSI claims involving endometriosis-related issues of appeal. METHODS: We searched Westlaw and Nexis Uni records, available as of January 2021, for federal appeals of SSDI and SSI claims including endometriosis as an impairment. Two independent reviewers screened full-text cases and extracted data. Framework Analysis was applied to courts' rationales regarding endometriosis-related issues of appeal. RESULTS: Eighty-seven appeals addressed an endometriosis-related issue. Three themes-evidence, treatment, and time-were identified across the decisions. The courts' discussions across themes exposed rationales and evidentiary requirements that posed challenges for claimants with endometriosis. The courts found subjective reports of symptoms insufficient evidence of impairment and positive responses to treatments to indicate cures or prevent claimants from demonstrating the necessary continuous 12 months of impairment. Some courts expected claimants to use treatments such as contraception or hysterectomy without addressing the risks of such treatments or the fact that they might have been counter to claimants' needs and preferences. CONCLUSIONS: Individuals with endometriosis face evidentiary obstacles and common misconceptions about disease, diagnosis, and treatment in disability claims. SSDI and SSI endometriosis claims are systematically disadvantaged, particularly among those without access to care. The health care, policy, and legal systems can leverage the findings in this study to create a more equitable disability application and review system for those with chronic pain conditions such as endometriosis.

Characterizing pathways of seafood access in small island developing states.

Ensuring healthy and sustainable food systems in increasing social, economic, and ecological change is a key global priority to protect human and environmental health. Seafood is an essential component of these food systems and a critical source of nutrients, especially in coastal communities. However, despite rapid transformations in aquatic food systems, and our urgent need to understand them, there is a dearth of data connecting harvested food production to actualized food consumption. Many analyses suggest institutional, legal, or technological innovations to improve food systems, but few have analyzed the pathways through which people already gain access to nutritious food. Here, using a random forest model and cluster analysis of a nationally representative data set from Kiribati, we operationalize access theory to trace the flows of consumptive benefit in a fisheries-based food system. We demonstrate that the market access mechanism is the key mechanism mediating seafood access in Kiribati, but importantly, the highest seafood consumption households showed lower market access, pointing to the importance of non-market acquisition (e.g., home production and gifting). We reveal six distinct household strategies that employ different sets of access mechanisms to ensure high levels of local seafood consumption in different contexts. We demonstrate the impacts of these strategies on the composition of household seafoods consumed, stressing the need to support these existing successful strategies. Finally, we point to key policy and management insights (e.g., improved infrastructure, shifts in species management) that may be more effective in reinforcing these existing pathways than commonly proposed food system interventions.

Oral ß-Lactams, Fluoroquinolones, or Trimethoprim-Sulfamethoxazole for Definitive Treatment of Uncomplicated Escherichia coli or Klebsiella Species Bacteremia From a Urinary Tract Source.

Background: Fluoroquinolones (FQs) are effective for oral step-down therapy for gram-negative bloodstream infections but are associated with unfavorable toxic effects. Robust data are lacking for trimethoprim-sulfamethoxazole (TMP-SMX) and high-bioavailability ß-lactams (HBBLs). Methods: In this multicenter observational cohort study, we simulated a 3-arm registry trial using causal inference methods to compare the effectiveness of FQs, TMP-SMX, or HBBLs for gram-negative bloodstream infections oral step-down therapy. The study included adults treated between January 2016 and December 2022 for uncomplicated Escherichia coli or Klebsiella species bacteremia of urinary tract origin who were who were transitioned to an oral regimen after ≤4 days of effective intravenous antibiotics. Propensity weighting was used to balance characteristics between groups. 60-day recurrence was compared using a multinomial Cox proportional hazards model with probability of treatment weighting. Results: Of 2571 patients screened, 648 (25%) were included. Their median age (interquartile range) was 67 (45-78) years, and only 103 (16%) were male. Characteristics were well balanced between groups. Compared with FQs, TMP-SMX had similar effectiveness (adjusted hazard ratio, 0.91 [95% confidence interval, .30-2.78]), and HBBLs had a higher risk of recurrence (2.19 [.95-5.01]), although this difference was not statistically significant. Most HBBLs (70%) were not optimally dosed for bacteremia. A total antibiotic duration ≤8 days was associated with a higher recurrence rate in select patients with risk factors for failure. Conclusions: FQs and TMP-SMX had similar effectiveness in this real-world data set. HBBLs were associated with higher recurrence rates but suboptimal dosing may have contributed. Further studies are needed to define optimal BL dosing and duration to mitigate treatment failures.

Variability in prostate cancer detection among radiologists and urologists using MRI fusion biopsy.

Objectives: The aim of this study is to evaluate the impact of radiologist and urologist variability on detection of prostate cancer (PCa) and clinically significant prostate cancer (csPCa) with magnetic resonance imaging (MRI)-transrectal ultrasound (TRUS) fusion prostate biopsies. Patients and methods: The Prospective Loyola University MRI (PLUM) Prostate Biopsy Cohort (January 2015 to December 2020) was used to identify men receiving their first MRI and MRI/TRUS fusion biopsy for suspected PCa. Clinical, MRI and biopsy data were stratified by radiologist and urologist to evaluate variation in Prostate Imaging-Reporting and Data System (PI-RADS) grading, lesion number and cancer detection. Multivariable logistic regression (MVR) models and area under the curve (AUC) comparisons assessed the relative impact of individual radiologists and urologists. Results: A total of 865 patients (469 biopsy-naïve) were included across 5 urologists and 10 radiologists. Radiologists varied with grading 15.4% to 44.8% of patients with MRI lesions as PI-RADS 3. PCa detection varied significantly by radiologist, from 34.5% to 66.7% (p = 0.003) for PCa and 17.2% to 50% (p = 0.001) for csPCa. Urologists' PCa diagnosis rates varied between 29.2% and 55.8% (p = 0.013) and between 24.6% and 39.8% (p = 0.36) for csPCa. After adjustment for case-mix on MVR, a fourfold to fivefold difference in PCa detection was observed between the highest-performing and lowest-performing radiologist (OR 0.22, 95%CI 0.10-0.47, p < 0.001). MVR demonstrated improved AUC for any PCa and csPCa detection when controlling for radiologist variation (p = 0.017 and p = 0.038), but controlling for urologist was not significant (p = 0.22 and p = 0.086). Any PCa detection (OR 1.64, 95%CI 1.06-2.55, p = 0.03) and csPCa detection (OR 1.57, 95%CI 1.00-2.48, p = 0.05) improved over time (2018-2020 vs. 2015-2017). Conclusions: Variability among radiologists in PI-RADS grading is a key area for quality improvement significantly impacting the detection of PCa and csPCa. Variability for performance of MRI-TRUS fusion prostate biopsies exists by urologist but with less impact on overall detection of csPCa.

Insights From a Community-Based Strategy to Assess Tobacco and Vape Shop Retailers' Implementation of Tobacco 21 Law in El Paso, Texas.

In 2019, the United States Congress passed Tobacco 21 (T21) legislation that raised the minimum legal sales age for tobacco products from 18 to 21. However, although the federal legislation superseded weaker state laws that were already in place in some states, including Texas, local guidance for retailers was inconsistent. Given that retailers are ultimately responsible for policy implementation, the American Heart Association (AHA) initiated a process of assessing retailers knowledge and perceptions of the law through a survey targeting all tobacco retailers and accompanying ethnography of a subset of vape shops in El Paso, Texas. The process yielded lessons learned for assessment of community-based policy implementation including key considerations for personnel and process that are applicable to other community-based assessment processes. While AHA considered an in-person approach ideal, having an alternate online response option was necessary. In addition, a focused approach and in-depth understanding of the purpose was key to responsiveness of the retailers.

Development of Youth-Centered Health Messaging Posters for High School-Based Health Clinics in Hawaii.

BACKGROUND: Youth may be reluctant to seek health care from school health providers due to feeling embarrassed or stigmatized in the health office environment or worried about their confidentiality. The purpose of this project was to create a set of youth-centered health posters that promote youth engagement with nursing staff and to standardize health messaging across high schools in Hawaii school-based clinics. METHODS: Two community advisory boards, 1 composed of 10 youth stakeholders (mean age 17 years) and the other of 7 adult stakeholders, informed poster development utilizing web-based discussion groups. The discussions were transcribed, and additional data was collected using field notes and anonymous digital messages. Adult advisory board members also provided feedback on suggested poster text through an online survey. RESULTS: Youth and adult advisory board participants identified 4 key health concerns facing youth: confidentiality, sexual health, relationships, and mental health. Based on input from the 2 advisory boards, 4 posters were developed, each centered on 1 key health issue. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: School-based posters can convey important messages to help youth understand their health care rights and responsibilities, as well as identify important issues open for discussion with nurses. CONCLUSION: Posters are an underutilized tool for school health providers to create welcoming, inclusive health care environments and facilitate health-related conversations with youth. This paper describes participant feedback about the characteristics of a memorable poster and briefly outlines current knowledge and recommendations for school health providers regarding each of the 4 health issues.

The Relationship between Gestational Weight Gain and Cesarean Delivery among Patients undergoing Induction of Labor.

OBJECTIVE: This study aimed to determine the impact of pregnancy weight gain above National Academy of Medicine (NAM) guidelines on cesarean delivery rates following induction. STUDY DESIGN: This is a secondary analysis of a prospective cohort study of patients who underwent induction at a single tertiary care center between July 2017 and July 2019. Included in the primary study were patients undergoing term (≥37 weeks) labor induction with a singleton gestation, intact membranes, and unfavorable cervical examination (Bishop score of ≤6 and cervical dilation ≤ 2 cm). Eligibility for this analysis was limited to patients with a documented prenatal body mass index (BMI) < 20 weeks' gestation. The primary exposure was gestational weight gain greater than NAM guidelines (WGGG) for a patient's initial BMI category. The primary outcome was cesarean delivery for any indication. RESULTS: Of 1,610 patients included in the original cohort, 1,174 (72.9%) met inclusion criteria for this analysis and 517 (44.0%) of these had weight gain above NAM guidelines. Of the entire cohort, 60.0% were Black and 52.7% had private insurance. In total, 160 patients (31%) with WGGG underwent cesarean compared with 127 patients (19.3%) without WGGG (p < 0.001), which equates to a 59% increased odds of cesarean when controlling for initial BMI category, parity, gestational diabetes, and indication for induction (Adjusted Odds Ratio [aOR] 1.58, 95% confidence interval [CI] 1.17-2.12). Among only nulliparous patients, WGGG was associated with an increased odds of cesarean (26.4 vs. 38.2%, aOR 1.50, 95% CI 1.07-2.10). In multiparous patients, however, there was no difference in cesarean between those with and without WGGG (8.8 vs. 14.1%, aOR 1.85, 95% CI 0.96-3.58). CONCLUSION: This study demonstrates that weight gain above NAM guidelines is associated with more than a 50% increased odds of cesarean. Patients should be informed of this association as gestational weight gain may be a modifiable risk factor for cesarean delivery. KEY POINTS: · Weight gain above NAM guidelines was associated with a 59% increased odds of cesarean delivery.. · Nulliparous patients with weight gain above NAM guidelines are at higher risk of cesarean delivery.. · No difference in cesarean delivery among multiparous patients regardless of gestational weight gain..
