Objective To estimate absolute risks of obstetric outcomes in the USA according to maternal age at first birth from age 15 to 45 separately by maternal race.Design and setting Population-based cohort study.Setting Vital statistics Birth Cohort-Linked Birth- Infant Death Data Files and Fetal Death Data Files in the USA.Participants 16 514 849 births to nulliparous women from 2004 to 2013.Outcome measures We estimated absolute risks of obstetric outcomes (multiple gestations, caesarean delivery, early and late preterm birth, small for gestational age birth, stillbirth, neonatal mortality, postneonatal infant mortality) at each year of maternal age from 15 to 45 years using logistic regression in the overall population and stratified by maternal race. We modelled maternal age flexibly to allow curvilinear shapes and plotted risk curves for each outcome.Results In the overall population, multiple gestations, caesarean delivery and stillbirth risks were lowest at young maternal ages with linear or quadratic increases with age. Curves for preterm birth, small for gestational age, neonatal mortality and postneonatal mortality were u or j shaped, with nadirs between 20 and 29 years, and elevated risks at both younger and older maternal ages. In race-stratified analyses, the shapes of the curves were generally similar across races. Risks increased for all women for all outcomes after age 30. However, increased risks at young maternal ages were most pronounced for white and Asian/Pacific Islander women, for whom young childbearing was least common. Conversely, risks at older ages were more pronounced for Black and American Indian/Alaska Native women, for whom delayed childbearing was least common.Conclusion Our findings confirm risks associated with first births to women younger than 20 and older than 30 years, provide easily interpretable risk curves and illuminate variability in these relationships across categories of maternal race in the USA.

The association between hospital volume and inpatient mortality for severe sepsis is unclear.To assess the effect of severe sepsis case volume and inpatient mortality.Retrospective cohort study from 646,988 patient discharges with severe sepsis from 3,487 hospitals in the Nationwide Inpatient Sample from 2002 to 2011.The exposure of interest was the mean yearly sepsis case volume per hospital divided into tertiles.Inpatient mortality.Compared with the highest tertile of severe sepsis volume (>60 cases per year), the odds ratio for inpatient mortality among persons admitted to hospitals in the lowest tertile (≤10 severe sepsis cases per year) was 1.188 (95% CI: 1.074-1.315), while the odds ratio was 1.090 (95% CI: 1.031-1.152) for patients admitted to hospitals in the middle tertile. Similarly, improved survival was seen across the tertiles with an adjusted inpatient mortality incidence of 35.81 (95% CI: 33.64-38.03) for hospitals with the lowest volume of severe sepsis cases and a drop to 32.07 (95% CI: 31.51-32.64) for hospitals with the highest volume.We demonstrate an association between a higher severe sepsis case volume and decreased mortality. The need for a systems-based approach for improved outcomes may require a high volume of severely septic patients.

Objective: To compare the impact of the coronavirus disease 2019 (COVID-19) pandemic on the psychological health of patients with infertility who have become pregnant with that of women who have not. Design: Prospective cohort study conducted from April 2020 to June 2020. The participants completed three questionnaires over this period. Setting: A single large, university-affiliated infertility practice. Patients: A total of 443 pregnant women and 1,476 women still experiencing infertility who completed all three questionnaires. Interventions: None. Main Outcome Measures: Patient-reported primary stressor over three months of the first major COVID-19 surge; further data on self-reported sadness, anxiety, loneliness, and the use of personal coping strategies. Results: Pregnant participants were significantly less likely to report taking an antidepressant or anxiolytic medication, were less likely to have a prior diagnosis of depression, were more likely to cite COVID-19 as a top stressor, and overall were less likely to practice stress-relieving activities during the first surge. Conclusions: Women who became pregnant after receiving treatment for infertility cited the pandemic as their top stressor and were more distressed about the pandemic than their nonpregnant counterparts but were less likely to be engaging in stress-relieving activities. Given the ongoing impact of the pandemic, patients with infertility who become pregnant after receiving treatment should be counseled and encouraged to practice specific stress-reduction strategies.

Abstract Background Exposure to ionizing radiation has been associated with insulin resistance and type 2 diabetes. In light of recent work showing an association between ambient particulate matter (PM) gross β-activity and gestational diabetes mellitus (GDM) among pregnant women, we examined pregnancy glucose levels in relation to PM gross β-activity to better understand this pathway. Methods Our study included 103 participants receiving prenatal care at Beth Israel Deaconess Medical Center in Boston, MA. PM gross β-activity was obtained from US Environmental Protection Agency’s RadNet program monitors, and blood glucose levels were obtained from the non-fasting glucose challenge test performed clinically as the first step of the 2-step GDM screening test. For each exposure window we examined (i.e., moving average same-day, one-week, first-trimester, and second-trimester PM gross β-activity), we fitted generalized additive models and adjusted for clinical characteristics, socio-demographic factors, temporal variables, and PM with an aerodynamic diameter ≤ 2.5 μm (PM2.5). Subgroup analyses by maternal age and by body mass index were also conducted. Results An interquartile range increase in average PM gross β-activity during the second trimester of pregnancy was associated with an increase of 17.5 (95% CI: 0.8, 34.3) mg/dL in glucose concentration. Associations were stronger among younger and overweight/obese participants. Our findings also suggest that the highest compared to the lowest quartile of one-week exposure was associated with 17.0 (95% CI: − 4.0, 38.0) mg/dL higher glucose levels. No associations of glucose were observed with PM gross β-activity during same-day and first-trimester exposure windows. PM2.5 was not associated with glucose levels during any exposure window in our data. Conclusions Exposure to higher levels of ambient PM gross β-activity was associated with higher blood glucose levels in pregnant patients, with implications for how this novel environmental factor could impact pregnancy health.

Infants born preterm are at increased risk of multiple morbidities and mortality. Why some women deliver preterm remains poorly understood. Prior studies have shown that cervical microRNA expression and DNA methylation are associated with the length of gestation. However, no study has examined the role of long noncoding RNAs (lncRNAs) in the cervix during pregnancy. To determine whether expression of lncRNAs is associated with length of gestation at delivery, we analyzed RNA from cervical swabs obtained from 78 women during pregnancy (mean 15.5, SD 5.0, weeks of gestation) who were participating in the Spontaneous Prematurity and Epigenetics of the Cervix (SPEC) Study in Boston, MA, USA. We used a PCR-based platform and found that 9 lncRNAs were expressed in at least 50% of the participants. Of these, a doubling of the expression of TUG1, TINCR, and FALEC was associated with shorter lengths of gestation at delivery [2.8 (95% CI: 0.31, 5.2); 3.3 (0.22, 6.3); and 4.5 (7.3, 1.6) days shorter respectively]. Of the lncRNAs analyzed, none was statistically associated with preterm birth, but expression of FALEC was 2.6-fold higher in women who delivered preterm vs. term (P = 0.051). These findings demonstrate that lncRNAs can be measured in cervical samples obtained during pregnancy and are associated with subsequent length of gestation at delivery. Further, this study supports future work to replicate these findings in other cohorts and perform mechanistic studies to determine the role of lncRNAs in the cervix during pregnancy.

Evolving evidence links maternal stress exposure to changes in placental DNA methylation of specific genes regulating placental function that may have implications for the programming of a host of chronic disorders. Few studies have implemented an epigenome-wide approach. Using the Infinium HumanMethylation450 BeadChip (450K), we investigated epigenome-wide placental DNA methylation in relation to maternal experiences of traumatic and non-traumatic stressors over her lifetime assessed using the Life Stressor Checklist-Revised (LSC-R) survey (n = 207). We found differential DNA methylation at epigenome-wide statistical significance (FDR = 0.05) for 112 CpGs. Additionally, we observed three clusters that exhibited differential methylation in response to high maternal lifetime stress. Enrichment analyses, conducted at an FDR = 0.20, revealed lysine degradation to be the most significant pathway associated with maternal lifetimes stress exposure. Targeted enrichment analyses of the three largest clusters of probes, identified using the gap statistic, were enriched for genes associated with endocytosis (i.e., SMAP1, ANKFY1), tight junctions (i.e., EPB41L4B), and metabolic pathways (i.e., INPP5E, EEF1B2). These pathways, also identified in the top 10 KEGG pathways associated with maternal lifetime stress exposure, play important roles in multiple physiological functions necessary for proper fetal development. Further, two genes were identified to exhibit multiple probes associated with maternal lifetime stress (i.e., ANKFY1, TM6SF1). The methylation status of the probes belonging to each cluster and/or genes exhibiting multiple hits, may play a role in the pathogenesis of adverse health outcomes in children born to mothers with increased lifetime stress exposure.

Prior work shows that ads related to abortion services often feature crisis pregnancy centers instead of abortion providers. We investigated whether a change in Google's advertising policy that required advertisers to disclose whether they provided abortion services increased the proportion of ads facilitating abortion self-referral.We used a standardized protocol to search online for abortion services before, during, and after the policy change; we performed searches in August 2016 to June 2017, June 2019, and October 2019, respectively, using Google, Bing, and Yahoo search engines. We performed searches for the 25 most populous U.S. cities and the 43 state capitals not already included. We classified up to the first 5 ads as facilitating abortion referral, hindering abortion referral, or providing neutral content. We compared search engine results using a chi-square test.Among ads returned by Google, those shown after the policy change were significantly more likely to facilitate abortion self-referral (66.7% vs. 44.2%; p = 0.003) and slightly less likely to hinder abortion self-referral (33.3% vs. 40.6%; p = 0.33) compared to before the change. These findings were reversed for ads shown by Bing and Yahoo; ads returned after the change were significantly less likely to facilitate abortion self-referral (24.6% vs. 32.8%; p = 0.01) and significantly more likely to hinder self-referral (28.3% vs. 21.6%; p = 0.03) compared to before the change.A policy requiring advertisers to disclose whether they provide abortion services was associated with increasing the proportion of ads facilitating self-referral. Similar policies should be considered by all search engines.While the internet is a convenient source of information that individuals often use to locate abortion providers, the information may not actually lead searchers to services. Search engines should consider restricting abortion-related advertising to organizations that provide abortion services in order to ensure that individuals searching online for abortion services are able to locate services in a direct and timely manner.

Oncology ,Obstetrics and Gynecology - Abstract
ObjectiveTo understand how treatment-related financial burden affects patients with gynecologic cancer and to identify targets for interventions to reduce financial toxicity.MethodsPatients with gynecologic cancer were invited to participate in a qualitative focus group study. Each participant completed an online, secure survey that included questions regarding diagnosis, treatment, employment status, and income. The Comprehensive Score for Financial Toxicity (COST) tool was used to measure economic burden (COST score 0–44), with lower scores indicating worse toxicity. Each participant then took part in a virtual semistructured focus group with a social worker and a study staff member. Three investigators independently analyzed the transcripts for common themes and reconciled disagreements through consensus.ResultsOver 60% of participants had private insurance, and 54% had moderate to high financial toxicity (COST scores ConclusionsOur findings suggest that patient-centered interventions to optimize insurance coverage and enhance care coordination may reduce financial toxicity. Both targets are potentially immediately actionable and could have downstream effects on health outcomes. Meanwhile, advocacy efforts to improve work leave policies and reduce out-of-pocket health expenditure are system-level interventions that also should be considered to curtail financial toxicity.

The substance use policy context continues to evolve. As tobacco control policies have become more restrictive, marijuana legalization has increased access to marijuana. Data suggest that prenatal conventional cigarette use is declining, while e-cigarette and marijuana use are increasing among persons preconception, prenatally, and postpartum. Policy evaluations have found that increasing cigarette taxes reduces prenatal smoking and improves birth outcomes; however, there have been few studies of e-cigarette policies or marijuana legalization on prenatal use or birth outcomes. It is important for clinicians to screen for prenatal substance use, as recommended by American College of Obstetricians and Gynecologists (ACOG), and understand how policies influence use among their patients.

OBJECTIVES: Lead exposure has devastating neurologic consequences for children and may begin in utero. The American College of Obstetricians and Gynecologists recommends prenatal lead screening using a risk factor-based approach rather than universal blood testing. The clinical utility of this approach has not been studied. We evaluated a risk-factor based questionnaire to detect elevated blood lead levels in pregnancy. METHODS: We performed a secondary analysis of a cohort of parturients enrolled to evaluate the association of lead with hypertensive disorders of pregnancy. We included participants in this analysis if they had a singleton pregnancy ≥34 weeks’ gestation with blood lead levels recorded. Participants completed a lead risk factor survey modified for pregnancy. We defined elevated blood lead as ≥2 μg/dL, as this was the clinically reportable level. RESULTS: Of 102 participants enrolled in the cohort, 92 had blood lead measured as part of the study. The vast majority (78%) had 1 or more risk factor for elevated lead using the questionnaire yet none had clinical blood lead testing during routine visits. Only two participants (2.2%) had elevated blood lead levels. The questionnaire had high sensitivity but poor specificity for predicting detectable lead levels (sensitivity 100%, specificity 22%). CONCLUSIONS FOR PRACTICE: Prenatal risk-factor based lead screening appears underutilized in practice and does not adequately discriminate between those with and without elevated blood levels. Given the complexity of the risk factor-based approach and underutilization, the benefit and cost-effectiveness of universal lead testing should be further explored.

Objectives. Little is known about the utility of simulation-based training in office gynaecology. The objective of this cross-sectional study was to evaluate the self-reported effectiveness and acceptability of the PelvicSim™ (VirtaMed), a high-fidelity mobile simulator, to train clinicians in intrauterine device (IUD) insertion. Methods. Clinicians at ambulatory healthcare centres participated in a PelvicSim IUD training programme and completed a self-administered survey. The survey assessed prior experience with IUD insertion, pre- and post-training competency and comfort and opinions regarding the acceptability of the PelvicSim. Results. The 237 participants were primarily female (97.5%) nurse practitioners (71.3%). Most had experience inserting the levonorgestrel LNG20 IUD and the copper T380A device, but only 4.1% had ever inserted the LNG14 IUD. For all three devices, participants felt more competent following training, with the most striking change reported for insertion of the LNG14 IUD. The majority of participants reported increased comfort with uterine sounding (57.7%), IUD insertion on a live patient (69.8%), and minimizing patient pain (72.8%) following training. Of the respondents, 89.6% reported the PelvicSim IUD insertion activities as “valuable” or “very valuable.” All participants would recommend the PelvicSim for IUD training, and nearly all (97.2%) reported that the PelvicSim was a better method to teach IUD insertion than the simple plastic models supplied by IUD manufacturers. Conclusions. These findings support the use of the PelvicSim for IUD training, though whether it is superior to traditional methods and improves patient outcomes requires evaluation.

Epidemiology - Abstract
Previous studies have examined the association between prenatal nitrogen dioxide (NO2)—a traffic emissions tracer—and fetal growth based on ultrasound measures. Yet, most have used exposure assessment methods with low temporal resolution, which limits the identification of critical exposure windows given that pregnancy is relatively short. Here, we used NO2 data from an ensemble model linked to residential addresses at birth to fit distributed lag models that estimated the association between NO2 exposure (resolved weekly) and ultrasound biometric parameters in a Massachusetts-based cohort of 9,446 singleton births from 2011–2016. Ultrasound biometric parameters examined included biparietal diameter (BPD), head circumference, femur length, and abdominal circumference. All models adjusted for sociodemographic characteristics, time trends, and temperature. We found that higher NO2 was negatively associated with all ultrasound parameters. The critical window differed depending on the parameter and when it was assessed. For example, for BPD measured after week 31, the critical exposure window appeared to be weeks 15–25; 10-parts-per-billion higher NO2 sustained from conception to the time of measurement was associated with a lower mean z score of −0.11 (95% CI: −0.17, −0.05). Our findings indicate that reducing traffic emissions is one potential avenue to improving fetal and offspring health.

Aim: We conducted a systematic review evaluating race/ethnicity representation in DNA methylomic studies of preterm birth. Data sources: PubMed, EMBASE, CINHAL, Scopus and relevant citations from 1 January 2000 to 30 June 2019. Study appraisal & synthesis methods: Two authors independently identified abstracts comparing DNA methylomic differences between term and preterm births that included race/ethnicity data. Results: 16 studies were included. Black and non-Hispanic Black deliveries were well represented (28%). However, large studies originating from more than 95% White populations were excluded due to unreported race/ethnicity data. Most studies were cross-sectional, allowing for reverse causation. Most studies were also racially/ethnically homogeneous, preventing direct comparison of DNA methylomic differences across race/ethnicities. Conclusion: In DNA methylomic studies, Black women and infants were well represented. However, the literature has limitations and precludes drawing definitive conclusions.

BackgroundLeft unabated, rising temperatures pose an escalating threat to human health. The potential effects of hot temperatures on fetal health have been under-explored. Here, we examined the association between prenatal ambient temperature exposure and fetal growth measures in a Massachusetts-based pregnancy cohort.MethodsWe used ultrasound measurements of biparietal diameter (BPD), head circumference (HC), femur length and abdominal circumference (AC), in addition to birthweight (BW), from 9446 births at Beth Israel Deaconess Medical Center from 2011 to 2016. Ultrasound scans were classified into three distinct gestational periods: 16–23 weeks, 24–31 weeks, 32+ weeks; and z-scores were created for each fetal growth measure using the INTERGROWTH-21st standards. We fitted distributed lag models to estimate the time-varying association between weekly temperature and fetal growth, adjusting for sociodemographic characteristics, seasonal and long-term trends, humidity and particulate matter (PM2.5).ResultsHigher ambient temperature was associated with smaller fetal growth measures. The critical window of exposure appeared to be Weeks 1–20 for ultrasound parameters, and high temperatures throughout pregnancy were important for BW. Associations were strongest for head parameters (BPD and HC) in early to mid-pregnancy, AC late in pregnancy and BW. For example, a 5ºC higher cumulative temperature exposure was associated with a lower mean AC z-score of -0.26 (95% CI: -0.48, -0.04) among 24–31-Week scans, and a lower mean BW z-score of -0.32 (95% CI: -0.51, -0.12).ConclusionHigher temperatures were associated with impaired fetal growth. This has major health implications given that extreme temperatures are more common and escalating.

Preterm prelabor rupture of membranes (PPROM), defined as rupture of membranes before the onset of labor at37 weeks' gestation, affects approximately 3% of all pregnancies. For PPROM prior to 34 weeks' gestation, in the absence of contraindications to expectant management, antibiotics are administered to increase the latency period and reduce the incidence of maternal and neonatal infection. The latency period additionally provides an opportunity for fetal presentation to change, which impacts the mode of delivery. It is important to better understand the incidence of spontaneous version after PPROM to enhance patient counseling with regard to the mode of delivery.To determine the incidence of discordant fetal presentation, resulting from spontaneous version, between admission for PPROM and time of delivery for cephalic and non-cephalic fetuses among patients diagnosed with PPROM prior to 34 weeks' gestation and to compare characteristics of those with and without discordant fetal presentation.We performed a retrospective cohort study of singleton pregnancies diagnosed with PPROM identified using ICD-9/10-CM codes,34 weeks' gestation, admitted to a tertiary care center's antepartum service from 2011-2018. Patients were included if the fetal presentation was documented by ultrasound within 48 h of admission and PPROM, and delivery occurred24 h after PPROM. Data are presented as proportions, median (interquartile range) or risk ratio and 95% confidence interval.We included 209 patients. Patient age, body mass index, parity, and race/ethnicity were similar among patients with cephalic and non-cephalic fetal presentations at admission. Patients with cephalic presentation at time of PPROM presented at a later gestational age than patients with a non-cephalic presentation. Among patients with a cephalic presentation at admission, the incidence of non-cephalic presentation at delivery was 11.7% (19/162), whereas with non-cephalic presentation at admission, the incidence of cephalic presentation at delivery was 21.3% (10/47). While there was an increased risk of spontaneous version resulting in a discordant presentation at delivery with non-cephalic presentation, this relationship was attenuated and not significant when adjusted for gestational age at time of PPROM. Patients with discordant presentation presented with PPROM at an earlier gestational age and had a longer latency period compared to patients with a concordant presentation. Patient age, body mass index, amniotic fluid assessment at admission, and infant birth weight were similar in those with and without a change in fetal presentation.Discordant fetal presentation resulting from spontaneous version from cephalic to non-cephalic presentation after PPROM occurred in 11.7% (19/162) of patients, while discordant presentation from non-cephalic to cephalic presentation occurred in 21.3% (10/47) of patients. Given the limited published data on spontaneous version after PPROM these results may impact patient counseling.

OBJECTIVE Evaluate 1-year outcomes of cervical cancer screening and treatment using primary high-risk human papillomavirus (HPV) testing in women living with human immunodeficiency virus (HIV). DESIGN Prospective cohort study. SETTING HIV treatment centre in Botswana. POPULATION Women living with HIV. METHODS Participants underwent cervical cancer screening with high-risk HPV testing and triage evaluation at baseline and 1-year follow up. Excisional treatment was offered as indicated. Histopathology was the reference standard. MAIN OUTCOME MEASURES Persistence, clearance and incidence of high-risk HPV infection; and persistence, progression, regression, cure and incidence of cervical dysplasia. RESULTS Among 300 women screened at baseline, 237 attended follow up (79%). High-risk HPV positivity significantly decreased from 28% at baseline to 20% at 1 year (P = 0.02). High-risk HPV persistence was 46% and clearance was 54%; incidence was high at 9%. Prevalence of cervical intraepithelial neoplasia Grade 2 (CIN2) or higher was most common in participants with incident high-risk HPV (53%). CIN2 or higher was also common in those with persistent high-risk HPV (32%) and even in those who cleared high-risk HPV (30%). Of the high-risk HPV-positive participants at baseline with

Aims Women with gestational diabetes mellitus (GDM) require postpartum glucose screening, as they have a 70% lifetime risk of developing Type 2 diabetes mellitus. However, less than half complete postpartum screening. Methods We conducted a retrospective chart review of patients who delivered at our institution from 2001 to 2019. Inclusion criteria were patients with gestational diabetes who were at least 18 years old and had delivered an infant at >24 weeks of gestation. Our primary outcome was completion of postpartum gestational diabetes screening. Results The majority of patients (62%) did not complete screening. After adjusted risk ratio analyses, the only variables that remained significantly associated with an increased likelihood of completing screening were Asian race and having prenatal care at one particular community health center, which served a predominantly Asian population. Conclusions This community health center protocol for scheduling patients with GDM that complied with recommendations for postpartum care, indicating that evidence-based methods can improve maternal health.

OBJECTIVE: To utilize a novel crowdsourcing method to measure financial toxicity and its effects amongst a national cohort of gynecologic cancer patients. METHODS: Crowdsourcing methods were used to administer an online survey to women in the United States with gynecologic cancers. We used the Comprehensive Score for Financial Toxicity (COST) tool to measure financial toxicity and the EQ-5D-3L to measure quality of life (QOL). Based on prior work, we defined high financial toxicity as a COST score ≤23. We assessed correlation of COST scores with QOL. We used log-binomial regression to examine associations between high financial toxicity and cost-coping strategies. RESULTS: Among the final study sample of 334 respondents, 87% were white, median age at diagnosis was 55 (interquartile range 47-63), 52% had stage III or IV disease and 90% had private insurance or Medicare. Median COST score was 24 (interquartile range 15-32) and 49% of respondents reported high financial toxicity. Greater financial toxicity was correlated with worse QOL (p

While some medical indications for cesarean delivery are clear, subjective provider and patient factors contribute to the rising cesarean delivery rates and marked disparities between racial/ethnic groups. We aimed to determine the association between language preference and risk of primary cesarean delivery. We conducted a retrospective cohort study of nulliparous, term, singleton, vertex (NTSV) deliveries of patients over 18 years old from 2011–2016 at an academic medical center, supplemented with data from the Massachusetts Department of Public Health. We used modified Poisson regression with robust error variance to calculate risk ratios for cesarean delivery between patients with English language preference and other language preference, with secondary outcomes of Apgar score, maternal readmission, blood transfusion, and NICU admission. Of the 11,298 patients included, 10.3% reported a preferred language other than English, including Mandarin and Cantonese (61.7%), Portuguese (9.7%), and Spanish (7.5%). The adjusted risk ratio for cesarean delivery among patients with a language preference other than English was 0.85 (95% CI 0.72–0.997; p = 0.046) compared to patients with English language preference. No significant differences in risk of secondary outcomes between English and other language preference were found. After adjusting for confounders, this analysis demonstrates a decreased risk of cesarean delivery among women who do not have an English language preference at one institution. This disparity in cesarean delivery rates in an NTSV population warrants future research, raising the question of what clinical and social factors may be contributing to these lower cesarean delivery rates.

ObjectiveThe Comprehensive Score for Financial Toxicity (COST) is a validated instrument measuring the economic burden experienced by patients with cancer. We evaluated the frequency of financial toxicity at different COST levels and stratified risk factors and associations with cost-coping strategies by financial toxicity severity.MethodsWe analyzed previously collected survey data of gynecologic oncology patients from two tertiary care institutions. Both surveys included the COST tool and questions assessing economic and behavioral cost-coping strategies. We adapted a proposed grading scale to define three groups: no/mild, moderate, and severe financial toxicity and used χ2, Fisher’s exact test, and Wilcoxon rank sum test to compare groups. We used Poisson regression to calculate crude and adjusted risk ratios for cost-coping strategies, comparing patients with moderate or severe to no/mild financial toxicity.ResultsAmong 308 patients, 14.9% had severe, 32.1% had moderate, and 52.9% had no/mild financial toxicity. Younger age, non-white race, lower education, unemployment, lower income, use of systemic therapy, and shorter time since diagnosis were associated with worse financial toxicity (all pConclusionsAmong a geographically diverse cohort of gynecologic oncology patients, nearly half reported financial toxicity (COST

General Engineering - Abstract
To evaluate whether an initial or two-day percent increase in serum beta-human chorionic gonadotropin (βhCG) is associated with ischemic placental disease (IPD) in singleton pregnancies after autologous or donor IVF.This was a secondary analysis of a retrospective cohort study of deliveries linked to IVF cycles at a single academic tertiary hospital and infertility treatment center. We included all patients (≥18 years old) who had a singleton live birth or intrauterine fetal demise (IUFD) resulting from either autologous fresh (n=1,347), autologous frozen (n=454), or donor (n=253) IVF cycles. Main outcome reassures: The primary outcome was a composite outcome of IPD or IUFD due to placental insufficiency. IPDs included preeclampsia, placental abruption, and small for gestational age (SGA).Neither initial βhCG nor two-day percent increases in βhCG were associated with an increased risk of IPD for any type of IVF cycle. Initial and two-day percent increases in βhCG were significantly higher when comparing frozen with fresh IVF and donor with autologous IVF (all P≤0.01).Among singleton autologous and donor IVF cycles, the initial and two-day percent increase in serum βhCG were not associated with IPD or its components. However, significant βhCG differences existed by cycle type and oocyte source.

Obstetrics and Gynecology - Abstract
Preeclampsia is a pregnancy complication that contributes substantially to perinatal morbidity and mortality worldwide. Existing approaches to modeling and prediction of preeclampsia typically focus either on predicting preeclampsia risk alone, or on the timing of delivery following a diagnosis of preeclampsia. As such, they are misaligned with typical healthcare interactions during which the 2 events are generally considered simultaneously.This study aimed to describe the "semicompeting risks" framework as an innovative approach for jointly modeling the risk and timing of preeclampsia and the timing of delivery simultaneously. Through this approach, one can obtain, at any point during the pregnancy, clinically relevant summaries of an individual's predicted outcome trajectories in 4 risk categories: not developing preeclampsia and not having delivered, not developing preeclampsia but having delivered because of other causes, developing preeclampsia but not having delivered, and developing preeclampsia and having delivered.To illustrate the semicompeting risks methodology, we presented an example analysis of a pregnancy cohort from the electronic health record of an urban, academic medical center in Boston, Massachusetts (n=9161 pregnancies). We fit an illness-death model with proportional-hazards regression specifications describing 3 hazards for timings of preeclampsia, delivery in the absence of preeclampsia, and delivery following preeclampsia diagnosis.The results indicated nuanced relationships between a variety of risk factors and the timings of preeclampsia diagnosis and delivery, including maternal age, race/ethnicity, parity, body mass index, diabetes mellitus, chronic hypertension, cigarette use, and proteinuria at 20 weeks' gestation. Sample predictions for a diverse set of individuals highlighted differences in projected outcome trajectories with regard to preeclampsia risk and timing, and timing of delivery either before or after preeclampsia diagnosis.The semicompeting risks framework enables characterization of the joint risk and timing of preeclampsia and delivery, providing enhanced, meaningful information regarding clinical decision-making throughout the pregnancy.

Oncology ,Obstetrics and Gynecology - Abstract
ObjectivesThe goal of our study was to identify preoperative factors in patients with endometrial intraepithelial neoplasia that are associated with concurrent endometrial cancer to select patients who may benefit from sentinel lymph node (SLN) assessment at the time of hysterectomy.MethodsRetrospective single institution cohort study of patients with a preoperative diagnosis of endometrial intraepithelial neoplasia who underwent hysterectomy with or without staging from January 2010 to July 2020. Modified Poisson regression was used to calculate risk ratios (RR) and 95% confidence intervals (CI).ResultsOf 378 patients with a preoperative diagnosis of endometrial intraepithelial neoplasia, 275 (73%) had endometrial intraepithelial neoplasia and 103 (27%) had invasive cancer on final pathology. Age (p=0.003), race (p=0.02), and hypertension (p=0.02) were significantly associated with concurrent endometrial cancer. The median preoperative endometrial stripe was significantly greater in the endometrial cancer group (14 mm (range 10–19)) than in the endometrial intraepithelial neoplasia group (11 mm (range 8–16); p=0.002). A preoperative endometrial stripe ≥20 mm was associated with double the risk of endometrial cancer on final pathology (crude RR 2.0, 95% CI 1.3 to 2.9) and preoperative endometrial stripe ≥15 mm was 2.5 times more likely to be associated with high risk Mayo criteria on final pathology (crude RR 2.5, 95% CI 1.2 to 5.2). Of those with concurrent endometrial cancer, 5% were stage IB, 29% had tumors >2 cm, and 1% had grade 3 histology. Only 3% of all patients underwent lymph node evaluation.ConclusionsIn a large cohort of patients with a preoperative diagnosis of endometrial intraepithelial neoplasia, less than a third had invasive cancer and even fewer had pathologic features considered high risk for nodal metastasis, arguing against the use of routine SLN dissection in these patients. Endometrial stripe ≥15 mm may be a useful preoperative marker to identify patients at higher risk for concurrent endometrial cancer and may be an important criterion for use of selective SLN dissection in carefully selected patients with endometrial intraepithelial neoplasia.

General Engineering - Abstract
We assessed understanding of the obstetric consent form between patients with English and Spanish language preference.This observational study included pregnant patients who identified as Hispanic/Latinx with English or Spanish language preference (defined as what language the patient prefers to receive healthcare information) and prenatal care providers at a large academic medical center from 2018 to 2021. Patient demographics, language preference, literacy, numeracy, acculturation, comprehension of the obstetric consent, and provider explanations were collected.We report descriptive statistics and thematic analysis with an inductive approach from 30 patients with English preference, 10 with Spanish preference, and 23 providers. The English group demonstrated 72% median correct responses about the consent form; the Spanish group demonstrated 61% median correct responses. Regardless of language, the participants demonstrated limited understanding of certain topics, such as risks of cesarean birth.Overall comprehension of key information in an obstetric consent form was low, with differences in language groups, which highlights opportunities for improvements in communication across language barriers. Innovations in the communication of critical pregnancy information for patients with limited English proficiency need to be developed and tested.

Objective Placenta accreta spectrum (PAS) is an obstetric diagnosis that carries significant risks. However, little is known about patient perceptions of care. This study was conducted to describe the patient experience, reported outcomes, and assess geographical variation in PAS care in the United States. Study Design Partnering with a PAS patient advocacy organization, we conducted an online survey of PAS patients. Perceptions of care and outcomes, and geographic variation were described. Results We received 108 responses (69% response rate); 103 respondents delivered in the United States. Demographic characteristics were similar across each region. Most (67%) reported at least one prior cesarean delivery and 53% reported placenta previa in the PAS pregnancy. Over half (63%) reported an antenatal suspicion of PAS and 66% of those respondents reported changing their delivery hospital as a result of their antenatal diagnosis. Though not statistically significant, both showed variability across regions (both p ≥0.60). Seventy-five percent of respondents with antenatal diagnosis reported their pregnancy was managed by a dedicated PAS care team, which did not differ by region (p = 0.80). A majority of respondents (75%) felt their PAS care team was prepared for their delivery; this too did not vary across regions (p = 0.97). Many respondents reported at least one physical (63%) or mental health (17%) adverse outcome as a result of their PAS pregnancy. Conclusion As reported by prior PAS patients, perception of care and outcomes are overall favorable. There are long-term physical and mental adverse consequences reported. Geographical variation is mixed, however, national guidelines are predominately followed. Key Points

Comparing one-year surgical outcomes of two widely used surgical procedures for apical suspension.The objective of this study is to compare anatomic outcomes after minimally invasive sacrocolpopexy (MISC) and vaginal uterosacral ligament suspension (vUSLS).This was a multicenter, retrospective cohort study through the Fellows' Pelvic Research Network. Patients with ≥ stage II pelvic organ prolapse (POP) who underwent MISC or vUSLS from January 2013 to January 2016, identified through the Current Procedural Terminology codes, with 1 year or longer postoperative data were included. Patients with prior POP surgery or history of connective tissue disorders were excluded. Anatomic success was defined as Pelvic Organ Prolapse Quantification System measurements: Ba/Bp ≤ 0 or C ≤ -TVL/2. Data were compared using χ 2 or Fisher exact tests. Continuous data were compared using Wilcoxon rank sum test.Three hundred thirty-seven patients underwent MISC (171 laparoscopic, 166 robotic) and 165 underwent vUSLS. The MISC group had longer operative time (205.9 minutes vs 187.5 minutes, P = 0.006) and lower blood loss (77.8 mL vs 187.4 mL; P0.001). Two patients (0.6%) in the MISC group had mesh exposure requiring surgical excision. Permanent suture exposure was higher after vUSLS (6.1%). At 1 year, anatomic success was comparable in the apical (322 [97%] MISC vs 160 [97%] vUSLS, P = 0.99) and posterior compartments (326 [97.6%] MISC vs 164 [99.4%] vUSLS; P = 0.28). Anterior compartment success was higher in the MISC group (328 [97.9%] vs 156 [94.9%], P = 0.04) along with longer total vaginal length (9.2 ± 1.8 vs 8.4 ± 1.5, P0.001).At 1 year, patients who underwent MISC or vUSLS had similar apical support. Low rates of mesh and suture exposures, less anterior recurrence, and longer TVL were noted after MISC.

Vaping is the act of inhaling an aerosol generated by an electronic cigarette (e-cigarette), a battery-powered device that heats a reservoir of liquid, typically nicotine-containing, to deliver contents to the user. E-cigarettes were initially introduced as a means of smoking cessation, although evidence of their effectiveness is limited. There is a widespread perception that these products are a safer alternative to conventional cigarettes, driven in large part by marketing efforts by e-cigarette manufacturers. Yet to achieve vaporization, temperatures are so high that components of the device hardware, such as metals, plastics, rubber and foam, are aerosolized and inhaled along with the vaporized e-liquid containing nicotine, flavoring and solvents. We do not fully understand the health consequences of such aerosol exposure, particularly long-term effects, but short-term negative cardiovascular and respiratory effects have been demonstrated. Very few studies have evaluated the reproductive effect of e-cigarette use. We do not know whether vaping during pregnancy affects birth outcomes or the lifelong health of the fetus. There has been an exponential rise in the use of e-cigarettes in the United States since their introduction, particularly among youths, while concurrently there has been a laudable reduction in conventional cigarette use. It is imperative that obstetrician-gynecologists have a basic understanding of e-cigarettes, screen all patients as is consistently done for conventional smoking, and provide resources to patients about potential negative consequences of use.

Objectives Lead exposure has been associated with hypertensive disorders of pregnancy. Angiogenic factors, including soluble fms-like tyrosine kinase 1 (sFlt1) and placental growth factor (PlGF), are aberrant in preeclampsia, but have not been correlated with lead levels. We evaluated the association of lead exposure with angiogenic factors. Study design This cross sectional study utilized a convenience sample of singleton pregnancies ≥34 weeks’ gestation. Blood lead and angiogenic factors were measured before delivery; bone lead was measured postpartum. We dichotomized bone and blood lead into the top tertile versus the bottom tertiles and used log-binomial regression to assess the association between lead and a high angiogenic ratio. Main outcome measures The outcomes were high sFlt1 to PlGF ratio and development of a hypertensive disorder of pregnancy. Results We enrolled 102 participants, of whom 98 had at least one lead measurement and an angiogenic factor result. Median bone lead was 3.8 ug/g (2.0 – 6.6) and median blood lead was 0.2 ug/dL (0.2 – 0.4). Incidence of hypertensive disorders of pregnancy was 31%. When comparing the highest tertile of bone lead to the bottom two tertiles, there was no association with a high sFlt1/PlGF ratio or hypertensive disorders of pregnancy. Similar results were observed for the exposure of blood lead. Conclusions Lead exposure was not an important contributor to an elevated angiogenic factor ratio or hypertensive disorders of pregnancy in our U.S. population. However, lead exposure was modest in our population and we cannot exclude a relationship with hypertensive disorders of pregnancy.

OBJECTIVES: To compare subjective and objective failure following posterior colporrhaphy with and without biologic graft augmentation. METHODS: We conducted a retrospective chart review and telephone survey of patients who underwent a posterior colporrhaphy with and without biologic graft augmentation from 2005-2019. Patients who underwent a sacrocolpopexy, uterosacral ligament suspensions, or anterior sacrospinous ligament fixation were excluded. Objective failure was defined as the need for retreatment as reported by the patient or identified in review of the medical records, or clinical exam with POPQ point Ap or Bp to the level of the hymen or beyond. Subjective failure was defined as a symptomatic vaginal bulge. RESULTS: There were 137 patients who met eligibility criteria for inclusion in the study. A total of 56 did not have valid contact information and therefore were excluded from the study. Of the 81 we were able to reach by telephone, 67 (83%) agreed to participate. There were 24 (36%) who had a native tissue repair and 43 (64%) who had biologic graft augmentation. Median telephone follow-up was 73 months (IQR 36 to 117). Objective failure rates were similar for the biologic graft (37%) and the native tissue (42%) groups (p=0.72). Subjective failure was twice as likely among the biologic graft group (60%) compared with the native tissue group (33%, p=0.03). Patients with a biologic graft reported a median PFDI-20 improvement of 31 (IQR 8 to 33), while those with a native tissue repair reported a median improvement of 45 (IQR 4 to 46). Overall, 78% were satisfied, 85% would recommend the procedure and 84% reported symptomatic improvement. Reoperation occurred for 15% of patients. CONCLUSION(S): While biologic graft-augmented posterior colporrhaphy may be a safe and effective treatment option, the use of biologic grafts in the posterior compartment does not appear to confer a significant long-term benefit to traditional posterior colporrhaphy.

The similar socioeconomic position of black and Hispanic women coupled with better birth outcomes among Hispanic women is termed the "Hispanic Paradox." However, birth outcome disparities among Hispanic women exist by maternal nativity. Persistent unequal exposure over time to stressors contributes to these disparities. We hypothesized that variation in maternal resilience to stressors also exists by race, ethnicity, and nativity. We utilized data from the Spontaneous Prematurity and Epigenetics of the Cervix study in Boston, MA (n = 771) where resilience was measured mid-pregnancy using the Connor Davidson Resilience Scale 25. We assessed resilience differences by race/ethnicity, by nativity then by race, ethnicity, and nativity together. We also assessed the risk of low resilience among foreign-born women by region of origin. We used Poisson regression to calculate risk ratios for low resilience, adjusting for maternal age, education, and insurance. Resilience did not differ significantly across race/ethnicity or by foreign-born status in the overall cohort. US-born Hispanic women were more likely to be in the low resilience tertile compared with their foreign-born Hispanic counterparts (adjusted RR 3.52, 95% CI 1.18-10.49). Foreign-born Hispanic women also had the lowest risk of being in the low resilience tertile compared with US-born non-Hispanic white women (aRR 0.33, 95% CI 0.11-0.98). Resilience did not differ significantly among immigrant women by continent of birth. Overall, foreign-born Hispanic women appear to possess a resilience advantage. Given that this group often exhibits the lowest rates of adverse birth outcomes, our findings suggest a deeper exploration of resilience among immigrant Hispanic women.

Background We previously reported an association between team training in the ambulatory setting and improvements in team climate at 6 and 12 months, but it is unknown whether improvements persist at 2 years. Study design From 2014 to 2015, we enrolled 20 organizations, each operating a varying number of health centers, into a teamwork training initiative. We evaluated teamwork outcomes at baseline and 2 years using a communication behaviors assessment, the TeamSTEPPS® Teamwork Perceptions Questionnaire (T-TPQ), and the Patients' Insights and Views of Teamwork (PIVOT) survey. Results At 2 years, use of TeamSTEPPS® tools and strategies remained increased compared to baseline at many health centers; results ranged from 32% of centers reporting increased use of pauses to identify the patient to 91% reporting increased use of standardized language. Staff T-TPQ responses indicated that TeamSTEPPS® implementation was associated with improved perceptions of teamwork in approximately half (49%) of statements at 2 years. Significant improvements occurred in over half of PIVOT survey statements, and patient satisfaction was significantly greater at 2 years compared to baseline. Conclusions Patient and staff views of teamwork were significantly improved 2 years after TeamSTEPPS® implementation in ambulatory reproductive health care centers, demonstrating positive long-term effects of teamwork training.

Objective To understand the compensation differences between male and female academic urogynecologists at public institutions. Methods Urogynecologists at public universities with publicly available salary data as of June 2019 were eligible for the study. We collected characteristics, including sex, additional advanced degrees, years of training, board certification, leadership roles, number of authored scientific publications, and total National Institutes of Health funding projects and number of registered clinical trials for which the physician was a principal or co-investigator. We also collected total number of Medicare beneficiaries treated and total Medicare reimbursement as reported by the Centers for Medicare & Medicaid Services. We used linear regression to adjust for potential confounders. Results We identified 85 academic urogynecologists at 29 public state academic institutions with available salary data eligible for inclusion in the study. Males were more likely to be an associate or a full professor (81%) compared with females (55%) and were more likely to serve as department chair, vice chair, or division director (59%) compared with females (30%). The mean annual salary was significantly higher among males ($323,227 ± $97,338) than females ($268,990 ± $72,311, P = 0.004). After adjusting for academic rank and leadership roles and years since residency, the discrepancy persisted, with females compensated on average $37,955 less annually. Conclusions Salaries are higher for male urogynecologists than female urogynecologists, even when accounting for variables such as academic rank and leadership roles. Physician compensation is complex; the differences observed may be due to variables that are not captured in this study. Nevertheless, the magnitude of disparity found in our study warrants further critical assessment of potential biases within the field.
