Polygenic risk scores (PRS) for type 2 diabetes (T2D) can improve risk prediction for gestational diabetes (GD), yet the strength of the association between genetic and lifestyle risk factors has not been quantified.To assess the association of PRS and physical activity in existing GD risk models and identify patient subgroups who may receive the most benefits from a PRS or physical activity intervention.The Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be cohort was established to study individuals without previous pregnancy lasting at least 20 weeks (nulliparous) and to elucidate factors associated with adverse pregnancy outcomes. A subcohort of 3533 participants with European ancestry was used for risk assessment and performance evaluation. Participants were enrolled from October 5, 2010, to December 3, 2013, and underwent genotyping between February 19, 2019, and February 28, 2020. Data were analyzed from September 15, 2020, to November 10, 2021.Self-reported total physical activity in early pregnancy was quantified as metabolic equivalents of task (METs). Polygenic risk scores were calculated for T2D using contributions of 84 single nucleotide variants, weighted by their association in the Diabetes Genetics Replication and Meta-analysis Consortium data.Estimation of the development of GD from clinical, genetic, and environmental variables collected in early pregnancy, assessed using measures of model discrimination. Odds ratios and positive likelihood ratios were used to evaluate the association of PRS and physical activity with GD risk.A total of 3533 women were included in this analysis (mean [SD] age, 28.6 [4.9] years). In high-risk population subgroups (body mass index ≥25 or aged ≥35 years), individuals with high PRS (top 25th percentile) or low activity levels (METs450) had increased odds of a GD diagnosis of 25% to 75%. Compared with the general population, participants with both high PRS and low activity levels had higher odds of a GD diagnosis (odds ratio, 3.4 [95% CI, 2.3-5.3]), whereas participants with low PRS and high METs had significantly reduced risk of a GD diagnosis (odds ratio, 0.5 [95% CI, 0.3-0.9]; P = .01).In this cohort study, the addition of PRS was associated with the stratified risk of GD diagnosis among high-risk patient subgroups, suggesting the benefits of targeted PRS ascertainment to encourage early intervention.

Objective The Illinois Perinatal HIV Prevention Act was passed to ensure universal HIV testing once during pregnancy and was extended in 2018 to add third trimester repeat HIV screening. The objectives of this analysis were to describe uptake of, and patient factors associated with, third trimester repeat HIV testing at a high-volume birthing center. Study Design This is a retrospective cohort study of people who delivered at a single tertiary care hospital in Illinois during 2018. Women who delivered before 27 weeks, had an intrauterine fetal demise, a known diagnosis of HIV, or no HIV test during pregnancy were excluded. Repeat testing was defined as an HIV test at or after 27 weeks' gestation after an earlier negative HIV test during the same pregnancy. The primary outcome was the proportion of people who received repeat testing prior to delivery. Bivariable analyses were performed to identify patient characteristics associated with documentation of repeat HIV testing. Results Of 12,053 people eligible for inclusion, 3.4% (n = 414) presented without a documented third trimester repeat HIV test. The proportion of people with repeat testing improved from 80 to >99% in the first year. Patient factors were largely not associated with testing performance although multiparous people were more likely to have documented repeat testing. Conclusion Rapid implementation of third trimester repeat HIV testing was achieved without disparity. Patient factors were largely not associated with testing performance which reinforces the goal of a universal screen to test all people equitably and effectively without bias. Key Points

Objective The experience of an unplanned cesarean birth may be a risk factor for mood disorders and other challenges in the postpartum period, yet qualitative data on the patient experience are limited. We sought to understand individuals' experiences of having an unplanned cesarean birth. Study Design This was a secondary analysis of a prospective qualitative investigation among low-income postpartum individuals at a single-, tertiary-care center in which the primary aim was to evaluate patients' postpartum pain experience after a cesarean birth. Participants completed a 60-minute face-to-face interview on postpartum days 2 to 3. Only participants who labored prior to their cesarean birth were included in this analysis. Transcripts were analyzed by two separate authors using the constant comparative method. Themes are illustrated using direct quotes. Results A total of 22 individuals were included in this analysis; the majority (n=16, 72.7%) experienced a primary cesarean birth. Over half (n=12, 54.5%) identified as Hispanic and one-third (n=7, 31.8%) identified as non-Hispanic Black race and ethnicity. Four themes regarding the experience of a cesarean birth after labor were identified, including feelings of anguish, belief that vaginal birth is “normal,” poor experiences with care teams, and feelings of self-efficacy. Subthemes were identified and outlined. Conclusion In this cohort, individuals who experienced an unplanned cesarean birth after labor expressed feelings of self-blame, failure, and mistrust. Given the association of unplanned cesarean birth with mood disorders in the postpartum period, efforts to enhance communication and support may offer a means of improving individual experiences.Key Points

Recent studies have suggested a possible benefit of valaciclovir prophylaxis to prevent vertical transmission after a positive serologic screen for primary maternal cytomegalovirus infection during pregnancy, although its cost-effectiveness remains uncertain.This study aimed to determine the circumstances under which universal first-trimester maternal serologic screening for maternal cytomegalovirus infection, with valaciclovir prophylaxis to prevent congenital cytomegalovirus, is cost-effective.This study was a decision analysis from the perspective of the pregnant person to assess whether universal maternal screening in the first trimester of pregnancy, with subsequent valaciclovir prophylaxis (8 g/day from the time of positive serologic screen for primary maternal cytomegalovirus infection to 21 weeks of gestation) for those who are acutely infected, is cost-effective compared with usual care (ie, no routine serologic screening but with amniocentesis if midtrimester sonographic findings suggest cytomegalovirus). For baseline estimates, this study assumed a 35% risk of congenital cytomegalovirus after primary maternal infection and a 71% risk reduction with valaciclovir. This study varied valaciclovir's efficacy to identify whether and at what threshold universal screening would be estimated to be cost-effective, compared with usual care. Monte Carlo analyses were performed. A willingness-to-pay threshold of $100,000/quality-adjusted life year was used to define cost-effectiveness.Under base case estimates, first-trimester universal screening and valaciclovir prophylaxis for seropositive pregnant persons with acute cytomegalovirus infection were not cost-effective, with a cost of $137,854 per maternal quality-adjusted life year but resulted in 14 fewer children affected with cytomegalovirus per 100,000 pregnancies compared with usual care. In 1-way sensitivity analysis, universal screening and treatment were estimated to be the cost-effective strategy if the incidence of primary maternal cytomegalovirus infection exceeds 2.6%, the baseline risk of vertical transmission of cytomegalovirus without prophylaxis is greater than 36.8%, and the risk reduction of vertical transmission of cytomegalovirus with valaciclovir prophylaxis exceeds 75.9%. In Monte Carlo analyses, first-trimester universal serologic screening with valaciclovir prophylaxis was estimated to be the cost-effective strategy in 46.8% of runs.Universal first-trimester serologic screening with valaciclovir prophylaxis is not the cost-effective strategy for antenatal management of cytomegalovirus under the base case estimates. Although universal screening is cost-effective in certain circumstances when the efficacy of valaciclovir exceeds the base case, that result was not robust to variation of estimates across their reasonable ranges. These data can inform future studies to evaluate screening and treatment to prevent congenital cytomegalovirus.

Objective The aim of the study is to examine clinical and demographic factors associated with trial of labor (TOL) among women with twin gestations eligible for a vaginal delivery. Study design This was a population-based cohort study of women giving birth to twin gestations in the United States (2012-2014). Inclusion criteria for the analysis included live births greater than 23 weeks' gestation and a cephalic presenting twin. Women with prior cesarean delivery were excluded. Women were categorized by whether they underwent a TOL. Clinical and demographic characteristics associated with TOL status were evaluated using multivariable logistic regression analyses. Secondary analyses with stratification by parity and by second twin presentation were performed. Results Of 90,000 women eligible for inclusion, a minority (39.3%) underwent TOL. Women who had a greater gestational age at delivery were more likely to have a TOL. In contrast, several demographic factors were associated with decreased likelihood of TOL, including maternal age >35 years and identifying as Hispanic or Asian compared with non-Hispanic White. No differences in odds of TOL were observed for women who were identified as non-Hispanic Black versus non-Hispanic White, nor were other demographic factors such as marital status, insurance status, or educational attainment associated with undergoing TOL. Clinical factors associated with decreased odds of TOL included nulliparity, obesity, and hypertensive disorders of pregnancy. Results did not substantively change when stratified by parity or second twin presentation, nor did findings differ in the subgroup who delivered at 32 weeks of gestation or greater. Conclusion In this large population of women with twins who were eligible for a TOL, a minority of individuals attempted a vaginal delivery. Demographic and clinical factors such as older maternal age, Asian or Hispanic racial or ethnic identification, nulliparity, and obesity are associated with decreased odds of undergoing TOL. Key points · Understanding disparities in trial of labor among patients with twins is key to promoting equity.. · Older maternal age and identifying as Hispanic or Asian were associated with lower odds of TOL.. · Nulliparity, obesity, and hypertension were associated with decreased odds of TOL..

Introduction Professional societies have urged providers to reduce opioid use for pain management. Accordingly, the objective of this study was to assess patient experiences related to postpartum pain management in an effort to better understand potential paths to achieve such a reduction. Methods This is a planned secondary analysis of a prospective observational study of opioid use following birth. In the primary study, women who received opioids as inpatients were queried about their pain management, including questions about pain experience, pain satisfaction, perceived areas for practice improvement, and the opportunity to leave additional comments. Participants who were prescribed opioids upon discharge completed postdischarge surveys with a similar opportunity for qualitative input. Data were analyzed using the constant comparative method to identify themes and subthemes. Results Of the 493 women enrolled in the primary analysis, 125 provided qualitative data. Three overarching themes regarding pain management were identified: positive experiences (n = 22), negative experiences (n = 19), and beliefs and preferences on opioid use and pain management (n = 28). Women with positive experiences reported satisfaction with timely pain medication administration and appreciation of open dialogue with their care team. In contrast, several negative experiences centered on tardy administration of pain medications, resulting in increased pain. Patients also perceived judgment, accusation, and excessive lecturing by staff when requesting opioid medications. Finally, participants expressed the necessity for opioids for postpartum pain management, as well as their desires for limiting opioid use, improved options for multimodal pain management, and increased communication with providers about pain regimens. Discussion Understanding women's perspectives and experiences regarding postpartum pain control is essential to improving care. Amid growing research on the role of maternity care providers in addressing the opioid crisis, women's voices are rarely solicited. These findings stress the importance of open and frequent dialogue between patients and providers and a need for multimodal pain management options.

This cross-sectional study examines whether perceived neighborhood safety is independently associated with adverse birth outcomes.

Objective The aim of the study is to investigate the association between intrapartum administration of magnesium sulfate in women with hypertensive disorders of pregnancy and postpartum hemorrhage. Study Design This was a retrospective cohort study of women diagnosed with a hypertensive disorder of pregnancy who delivered singleton gestations >32 weeks at a single, large volume tertiary care center between January 2006 and February 2015. Women who received intrapartum magnesium sulfate for seizure prophylaxis were compared with women who did not receive intrapartum magnesium sulfate. The primary outcome was frequency of postpartum hemorrhage. Secondary outcomes included estimated blood loss, uterine atony, and transfusion of packed red blood cells. Bivariable analyses were used to compare the frequencies of each outcome. Multivariable logistic regression models examined the independent associations of magnesium sulfate with outcomes. Results Of 2,970 women who met inclusion criteria, 1,072 (36%) received intrapartum magnesium sulfate. Women who received magnesium sulfate were more likely to be nulliparous, publicly insured, of minority race or ethnicity, earlier gestational age at delivery, and undergo labor induction. The frequency of postpartum hemorrhage was significantly higher among women who received magnesium sulfate compared with those who did not (12.4 vs. 9.3%, p = 0.008), which persisted after controlling for potential confounders. Of secondary outcomes, there was no difference in estimated blood loss between women who did and did not receive magnesium sulfate (250 mL [interquartile range 250–750] vs. 250 mL [interquartile range 250–750], p = 0.446). However, compared with women who did not receive magnesium sulfate, women who received magnesium sulfate had a greater frequency of uterine atony (8.9 vs 4.9%, p Conclusion Intrapartum magnesium sulfate administration to women with hypertensive disorders of pregnancy is associated with increased odds of postpartum hemorrhage, uterine atony, and red blood cell transfusion.

The aim of this study was to assess whether social vulnerability among foreign-born pregnant women living with HIV is associated with maternal viremia during pregnancy.This retrospective cohort study included all foreign-born pregnant women living with HIV who received prenatal care in a multidisciplinary prenatal clinic between 2009 and 2018. A licensed clinical social worker evaluated all women and kept detailed clinical records on immigration status and social support. Social vulnerability was defined as both living in the United States for less than 5 years and reporting no family or friends for support. The primary outcome was evidence of viral non-suppression after achievement of initial suppression. Secondary outcomes were the proportion of women who required 12 weeks after starting antiretroviral therapy to achieve viral suppression, median time to first viral suppression (in weeks) after initiation of antiretroviral therapy, and the proportion who missed ≥ 5 doses of antiretroviral therapy. Bivariable analyses were performed.A total of 111 foreign-born women were eligible for analysis, of whom 25 (23%) were classified as socially vulnerable. Social and clinical characteristics of women diverged by social vulnerability categorization but no differences reached statistical significance. On bivariable analysis, socially-vulnerable women were at increased risk for needing 12 weeks to achieve viral suppression (relative risk: 1.78, 95% confidence interval: 1.18-2.67), though there was no association with missing ≥ 5 doses of antiretroviral therapy or median time to viral suppression after initiation of antiretroviral therapy.Among foreign-born, pregnant women living with HIV, markers of virologic control during pregnancy were noted to be worse among socially-vulnerable women. Insofar as maternal viremia is the predominant driver of perinatal transmission, closer clinical surveillance and support may be indicated in this population.· 23% of foreign-born pregnant women living with HIV were identified as socially vulnerable.. · Socially-vulnerable women were at higher risk for re-emergent viremia (24 vs. 7%, RR 3.44).. · Socially-vulnerable women were at higher risk for needing12 weeks to become aviremic (64 vs. 36%, RR: 1.7)..

Obstetrical clinical trials are the foundation of evidence-based medicine during pregnancy. As more obstetrical trials are conducted, understanding the publication characteristics of these trials is of utmost importance to advance obstetrical health.This study aimed to characterize the frequency of publication and trial characteristics associated with publication among obstetrical clinical trials in the United States. We additionally sought to examine time from trial completion to publication.This was a cross-sectional analysis of completed obstetrical trials with an intervention design and at least 1 site in the United States registered to ClinicalTrials.gov from 2007 to 2019. Trial characteristics were cross-referenced with PubMed to determine publication status up to 2021 using the National Clinical Trial identification number. Bivariable analyses were conducted to determine trial characteristics associated with publication. Multivariable logistic regression models controlling for prespecified covariates were generated to estimate the relationship between funding, primary purpose, and therapeutic foci with publication. Additional exploratory analyses of other trial characteristics were conducted. Time to publication was analyzed using Kaplan-Meier curves and Cox regression models.Of the 1879 obstetrical trials with registered completion, a total of 575 (30.6%) had at least 1 site in the United States, were completed before October 1, 2019, and were included in this analysis. Between October 2007 and October 2019, fewer than two-thirds (N=348, 60.5%) of trials reached publication. Annual rates of publication ranged from 46.4% in 2018 to 70.0% in 2007. No difference was observed in publication by funding, primary purpose, or therapeutic foci (all P.05). Trials with characteristics indicating high trial quality-including randomized allocation scheme, ≥50 participants enrolled, ≥2 sites, and presence of a data safety monitoring committee-had increased odds of publication compared with those without such characteristics (all P.05). For example, studies with randomized allocation of intervention had 2-fold greater odds of publication than nonrandomized studies (adjusted odds ratio, 2.09; 95% confidence interval, 1.30-3.37). Studies with ≥150 participants had nearly 8-fold odds of publication (adjusted odds ratio, 7.90; 95% confidence interval, 3.78-17.49) relative to studies with50 participants. Temporal analysis demonstrated variability in time to publication among obstetrical trials, with a median time of 20.1 months after trial completion, and with most trials that reached publication having been published by 40 months. No difference was observed in time to publication by funding, primary purpose, or therapeutic foci (all P.05).Publication of obstetrical trials remains suboptimal, with significant differences observed between trials with indicators of high quality and those without. Most trials that reach publication are published within 2 years of registered completion on ClinicalTrials.gov.

ImportancePolygenic risk scores (PRS) for Type II Diabetes Mellitus (T2DM) can improve risk prediction for Gestational Diabetes Mellitus (GDM), yet the strength of the relationship between genetic and lifestyle risk factors has not been quantified.ObjectiveTo assess the effects of PRS and physical activity on existing GDM risk models and identify patient subgroups who may receive the most benefits from receiving a PRS or activity intervention.Design, Settings, and ParticipantsThe Nulliparous Pregnancy Outcomes Study: Monitoring Mothers-to-Be (nuMoM2b) study was established to study individuals without previous pregnancy lasting 20 weeks or more (nulliparous) and to elucidate factors associated with adverse pregnancy outcomes. A sub-cohort of 3,533 participants with European ancestry were used for risk assessment and performance evaluation.ExposuresSelf-reported total physical activity in early pregnancy was quantified as metabolic equivalent of tasks (METs) in hours/week. Polygenic risk scores were calculated for T2DM using contributions of 85 single nucleotide variants, weighted by their association in the DIAbetes Genetics Replication And Meta-analysis (DIAGRAM) Consortium data.Main Outcomes and MeasuresPrediction of the development of GDM from clinical, genetic, and environmental variables collected in early pregnancy. The risk model is assessed using measures of model discrimination and calibration. Odds ratio and positive likelihood ratio were used for evaluating the effect of PRS and physical activity on GDM risk.ResultsIn high-risk population subgroups (body mass index ≥ 25 or age ≥ 35), individuals with PRS in the top 25th percentile or METs below 450 have significantly increased odds of GDM diagnosis. Participants with both high PRS and low METs have three times higher odds of GDM diagnosis than the population. Conversely, participants with high PRS and METs ≥ 450 do not exhibit increased odds of GDM diagnosis, and those with low METs and low PRS have reduced odds of GDM. The relationship between PRS and METs was found to be nonadditive.Conclusions and RelevanceIn high-risk patient subgroups the addition of PRS resulted in increased risk of GDM diagnosis, suggesting the benefits of targeted PRS ascertainment to encourage early intervention. Increased physical activity is associated with decreased risk of GDM, particularly among individuals genetically predisposed to T2DM.Key PointsQuestionDo genetic predisposition to diabetes and physical activity in early pregnancy cooperatively impact risk of Gestational Diabetes Mellitus (GDM) among nulliparas?FindingsRisk of GDM diagnosis increases significantly for nulliparas with high polygenic risk score (PRS) and with low physical activity. The odds ratio of developing GDM with high PRS was estimated to be 2.2, 1.6 with low physical activity, and 3.5 in combination.MeaningPhysical activity in early pregnancy is associated with reduced risk of GDM and reversal of excess risk in genetically predisposed individuals. The interaction between PRS and physical activity may identify subjects for targeted interventions.

Objective The objective was to assess temporal trends in postpartum opioid prescribing, opioid use, and pain control satisfaction. Study Design This is a prospective observational study of postpartum patients who delivered at a large tertiary care center (May 2017–July 2019). Inpatient patients were screened for eligibility; those meeting eligibility criteria who used inpatient opioids were approached for prospective survey participation which probed inpatient and outpatient postpartum pain control. The amount of opioids used during inpatient hospitalization and the amount of opioids prescribed at discharge were obtained from medical records. The primary outcome was the difference in opioid prescribing at discharge over time, measured by (1) the proportion of participants who received an opioid prescription at discharge and (2) for those who received an opioid prescription, the total morphine milligram equivalents of the prescription. Additional outcomes were inpatient and outpatient opioid use and patient-reported satisfaction with postpartum pain control. Trends over time were evaluated using nonparametric tests of trend. Results Of 2,503 postpartum patients screened for eligibility, a majority (N = 1,425; 60.8%) did not use an opioid as an inpatient. Over the study period, there was a significant decline in the proportion of patients who used an opioid while inpatient (z-score = − 11.8; p Conclusion In this population, both the frequency and amount of opioid use in the postpartum period declined from 2017 to 2019. This decrease in opioid prescribing was not associated with changes in patient-reported satisfaction with pain control. Key Points

BACKGROUND Birth rates among women living with HIV (WLHIV) have increased recently, with many experiencing multiple pregnancies. Yet, viral suppression is often not sustained between pregnancies. In addition, protease inhibitors (PIs) have been associated with preterm birth, but associations between integrase strand transfer inhibitors (INSTIs) and preterm birth are less well characterized. METHODS We studied WLHIV with ≥2 live-born infants enrolled into the Pediatric HIV/AIDS Cohort Study Surveillance Monitoring for Antiretroviral Treatment Toxicities (SMARTT) study between 2007 and 2018, comparing CD4 counts and viral loads (VLs) between 2 consecutive SMARTT pregnancies. We evaluated associations of covariates with CD4 and viral suppression and the association of PI/INSTI use during pregnancy with odds of preterm birth. RESULTS There were 736 women who had ≥2 live-born children enrolled in SMARTT (1695 pregnancies). Median CD4 counts remained stable over repeat pregnancies. Although >80% of women achieved VL suppression during pregnancy, more than half had a detectable VL early in their subsequent pregnancy. In adjusted models including all singleton pregnancies, an increased odds of preterm birth was observed for women with first trimester PI initiation (adjusted odds ratio: 1.97; 95% confidence interval: 1.27 to 3.07) compared with those not receiving PIs during pregnancy and for first trimester INSTI initiation (adjusted odds ratio: 2.39; 95% confidence interval: 1.04 to 5.46) compared with those never using INSTIs during pregnancy. CONCLUSIONS Most WLHIV achieved VL suppression by late pregnancy but many were viremic early in subsequent pregnancies. First trimester initiation of PIs or INSTIs was associated with a higher risk of preterm birth.

OBJECTIVE: To examine whether an insulin protocol for intrapartum glucose control among parturients with diabetes was associated with improved outcomes. METHODS: This is a retrospective cohort study of women with pregestational or gestational diabetes delivering a live-born neonate at Northwestern Memorial Hospital. Before 2011, women with diabetes were given intravenous insulin or glucose during labor at the discretion of the on-call endocrinologist. In 2011, a standardized protocol was designed to titrate insulin and glucose infusions. Outcomes were compared between two time periods: 1/2005–12/2010 (before implementation) and 1/2012–12/2017 (after implementation) with 2011 excluded to account for a phase-in period. Maternal outcomes included intrapartum hyperglycemia (blood glucose > 125 mg/dL) and hypoglycemia (blood glucose < 60 mg/dL). Neonatal outcomes included hypoglycemia (blood glucose < 50 mg/dL), intensive care admission, and intravenous dextrose therapy. T tests, Wilcoxon rank sum tests, and chi square tests were used for bivariable analyses. Linear and logistic multivariable regression were used to account for confounding factors. RESULTS: Of 3,689 women, 928 (25.2%) delivered prior to 2011. After protocol implementation, frequencies of both maternal intrapartum hyperglycemia (51.3% vs. 37.9%) and hypoglycemia decreased (6.1% vs. 2.5%), both p < 0.001; respective adjusted odds ratio [adj. OR] 0.64, 95% confidence interval [CI] 0.54–0.77 and 0.50, 95% CI 0.33–0.78. The frequency of neonatal hypoglycemia, however, increased (36.6% vs. 49.2%, p < 0.001; adj. OR 1.73, 95% CI 1.45–2.07). Admission to the neonatal intensive care unit and need for intravenous dextrose therapy were similar across time periods. CONCLUSIONS: A formal protocol to manage insulin and glucose infusions for parturients with diabetes was associated with improved intrapartum maternal glucose control, but an increased frequency of neonatal hypoglycemia.

With the coronavirus disease 2019 (COVID-19) pandemic in the United States, a majority of states have instituted "shelter-in-place" policies effectively quarantining individuals-including pregnant persons-in their homes. Given the concern for COVID-19 acquisition in health care settings, pregnant persons with high-risk pregnancies-such as persons living with HIV (PLHIV)-are increasingly investigating the option of a home birth. Although we strongly recommend hospital birth for PLHIV, we discuss our experience and recommendations for counseling and preparation of pregnant PLHIV who may be considering home birth or at risk for unintentional home birth due to the pandemic. We also discuss issues associated with implementing a risk mitigation strategy involving high-risk births occurring at home during a pandemic. KEY POINTS: · Coronavirus disease 2019 pandemic has increased interest in home birth.. · Women living with HIV are pursuing home birth.. · Safe planning is paramount for women living with HIV desiring home birth, despite recommending against the practice..

As gestational surrogacy (a process by which intended parents contract with a woman to carry a fetus that the intended parents will raise) increases across the United States, it is imperative that obstetrician/gynecologists understand the unique nuances of caring for patients who are gestational surrogates. Gestational surrogacy offers a route to parenthood for individuals and families who may otherwise have limited options. Understanding surrogacy requires multiple ethical considerations about the potential medical and psychosocial effects on gestational surrogates as well as the families built through surrogacy. There is a dearth of research on the subject, particularly in the United States and other countries that practice compensated surrogacy. Here we seek to review the process of gestational surrogacy in the United States, including the legal landscape, current trends in gestational surrogacy use, and what is known about the medical and social effects of this process on all participants. We also aim to highlight the limitations of available data and to identify topics for future research to provide optimal evidence-based and just care for these patients.

Objective The aim of this study is to determine the relationship between urban food deserts and frequency and obstetric outcomes related to gestational diabetes. Study Design We conducted a retrospective cohort study of singleton births in Chicago from 2010 to 2014. Birth certificate data were analyzed and geomapped by census tract. Census tracts were categorized as “food deserts” according to the USDA Food Access Research Atlas. The primary outcome was frequency of gestational diabetes. Secondary outcomes were assessed among women with gestational diabetes and their neonates. Results Of the 191,947 eligible women, 8,709 (4.5%) were diagnosed with gestational diabetes. Those in food deserts were more likely to be younger, obese, minority race/ethnicity, and multiparous. Women in food deserts were less likely to develop gestational diabetes (3.8 vs. 4.8%, p Conclusion In contrast to prior work, women in Chicago living within food deserts were less likely to develop gestational diabetes and did not experience poorer outcomes, suggesting environmental factors other than food access contribute to perinatal outcomes.

Objective This study aims to investigate neonatal outcomes of triplet gestations conceived via in vitro fertilization (IVF) compared with those not conceived by IVF. Study Design This is a retrospective cohort study of women who delivered a triplet gestation ≥24 weeks at a large academic center (2005–2016). Women with unknown mode of conception were excluded. Women who conceived via IVF were compared with those conceiving spontaneously or through non-IVF fertility treatments. The primary outcome was a composite severe neonatal morbidity (respiratory distress syndrome, necrotizing enterocolitis, severe intraventricular hemorrhage, retinopathy of prematurity, neonatal sepsis, or death). Bivariate comparisons were made by mode of conception and unadjusted generalized estimating equations were used to estimate odds ratios (OR) after accounting for the clustering of neonate by mother. Results Among 82 women included in this analysis, 51 (62%) conceived via IVF. Women who conceived via IVF were older (35.2 vs. 30.7, p Conclusion Neonatal outcomes among triplet gestations did not differ by IVF in this well-characterized, single-center cohort.

Existing data suggest that obstetric outcomes for individuals with twin gestations, who have gestational diabetes mellitus (GDM), may be comparable to those who do not have GDM, yet studies are limited by small sample sizes. The aim of this study was to examine differences in maternal and neonatal outcomes of individuals with twin gestations based on presence of GDM. This was a population-based retrospective cohort study of individuals giving birth to twins in the United States between 2012 and 2014. Inclusion criteria were live births (≥24 weeks) and available information on GDM status; individuals with pregestational diabetes were excluded. Participants were categorized as either having had or not had GDM. Multivariable logistic regression was utilized to assess the independent association of GDM with adverse maternal outcomes, whereas generalized estimating equation models were used to estimate associations with neonatal outcomes to account for clustering. Of 173,196 individuals meeting inclusion criteria, 13,194 (7.6%) had GDM. Individuals with GDM were more likely to be older, identify as Hispanic or Asian race and ethnicity, married, college educated, privately insured, and obese than those without GDM. After adjusting for potential confounding variables, those with GDM were more likely to have hypertensive disorders (18.0 vs. 10.2%) and undergo cesarean delivery (51.2 vs. 47.3%). Neonates born to individuals with GDM were more likely to require mechanical ventilation for greater than 6 hours (6.5 vs. 5.6%) and experience neonatal intensive care unit (NICU) admission (41.1 vs. 36.2%), but were less likely to be low birth weight or have small for gestational age status (16.2 vs. 19.5%). Findings were confirmed in a sensitivity analysis of neonates born at 32 weeks of gestation or greater. Odds of poor obstetric and neonatal outcomes are increased for individuals with twin gestations complicated by GDM.· Individuals with GDM and twin gestation have higher odds of developing hypertensive disorders during pregnancy and of undergoing cesarean delivery.. · Neonates of such pregnancies are less likely to be low birth weight or small for gestational age.. · Neonates of pregnancies complicated by GDM and twin gestation are more likely to require mechanical ventilation and experience NICU admission..

BACKGROUND Pregnant individuals often seek online information regarding health concerns on free and accessible platforms such as YouTube. Use of supplemental information may increase when pregnancy is complicated by diagnoses of sexually transmitted infections (STIs) such as herpes simplex virus (HSV) given the sensitive nature of these diagnoses. OBJECTIVE The objective of this study is to evaluate the quality and content of YouTube videos about HSV during pregnancy. METHODS A search of videos on YouTube was conducted using four ‘HSV and pregnancy’ terms. The first 60 videos from each keyword search were collected and reviewed. The quality and reliability of each video were assessed using the DISCERN instrument and the JAMA Benchmark tool. An expert-developed topic list was used to generate a content score, which assessed video comprehensiveness. Videos were further categorized as either “high” or “low” quality, with high quality videos having both a DISCERN score >3 and a content score >4. Descriptive statistical analyses and comparisons of videos by source, viewing rates, duration, and subscriber number were performed. RESULTS A total of 92 unique videos were evaluated; the median content score was 3 out of 7 (IQR 1,5) and median DISCERN score was 2.12 of 8 (IQR 1.75, 2.75), representing moderate video comprehensiveness and low reliability. Only 13 (14.1%) videos met criteria for high quality. Every video categorized as high quality came from medical or online education sources. Low-quality videos had 3.5-times more subscribers & 7-fold higher viewing rates than high-quality videos (p=0.002, p=0.001). Video duration was longer for high-quality videos (15min vs 7.7min; p CONCLUSIONS Few high-quality, reliable and comprehensive videos regarding HSV in pregnancy exist on YouTube. Low-quality videos generally have more subscribers and views, suggesting that individuals seeking information on YouTube may encounter incomplete resources.

Objective Our objective was to investigate the association between maternal outcomes and twin chorionicity in a large, contemporary obstetric population. Study Design Retrospective cohort study was conducted at a single, large tertiary care center. Prenatal and inpatient records for all individuals with twin gestations were reviewed from 2000 to 2016. Patients with monoamniotic twins, higher-order multiples reduced to twins, multiple sets of twins in the study period, or undetermined chorionicity were excluded. Patients with monochorionic twins were compared with those with dichorionic twins. The co-primary outcomes were gestational diabetes mellitus and hypertensive disorders of pregnancy. Secondary outcomes included cesarean delivery, preterm delivery, postpartum hemorrhage, and other maternal outcomes. Bivariate and multivariate analyses were performed to assess associations of chorionicity with maternal outcomes. Results Of the 2,979 patients eligible for inclusion, 2,627 (88.2%) had dichorionic twin gestations and 352 (11.8%) had monochorionic twin gestations. Patients with monochorionic twins were less likely to self-identify as non-Hispanic White and to have conceived via assisted reproductive technology but were more likely to be publicly insured, multiparous and have prenatal care with a maternal–fetal medicine provider. Neither gestational diabetes mellitus (6.8% monochorionic vs. 6.2% dichorionic, p = 0.74; adjusted odds ratio [OR] 1.06, 95% confidence interval (CI) 0.60–1.86) nor hypertensive disorders of pregnancy (21.9% monochorionic vs. 26.3% dichorionic, p = 0.09; adjusted OR 0.99, 95% CI, 0.71–1.38) differed by chorionicity. Of the secondary maternal outcomes, patients with monochorionic twins experienced a lower frequency of cesarean delivery (46.0 vs. 61.8%, p Conclusion The odds of gestational diabetes mellitus and hypertensive disorders of pregnancy do not appear to differ by twin chorionicity. Key Points

Background Hypertensive disorders of pregnancy are growing public health problems that contribute to maternal morbidity, mortality, and future risk of cardiovascular disease. Given established rural‐urban differences in maternal cardiovascular health, we described contemporary trends in new‐onset hypertensive disorders of pregnancy in the United States. Methods and Results We conducted a serial, cross‐sectional analysis of 51 685 525 live births to individuals aged 15 to 44 years from 2007 to 2019 using the Centers for Disease Control and Prevention Natality Database. We included gestational hypertension and preeclampsia/eclampsia in individuals without chronic hypertension and calculated the age‐adjusted incidence (95% CI) per 1000 live births overall and by urbanization status (rural or urban). We used Joinpoint software to identify inflection points and calculate rate of change. We quantified rate ratios to compare the relative incidence in rural compared with urban areas. Incidence (95% CI) of new‐onset hypertensive disorders of pregnancy increased from 2007 to 2019 in both rural (48.6 [48.0–49.2] to 83.9 [83.1–84.7]) and urban (37.0 [36.8–37.2] to 77.2 [76.8–77.6]) areas. The rate of annual increase in new‐onset hypertensive disorders of pregnancy was more rapid after 2014 with greater acceleration in urban compared with rural areas. Rate ratios (95% CI) comparing incidence of new‐onset hypertensive disorders of pregnancy in rural and urban areas decreased from 1.31 (1.30–1.33) in 2007 to 1.09 (1.08–1.10) in 2019. Conclusions Incidence of new‐onset hypertensive disorders of pregnancy doubled from 2007 to 2019 with persistent rural‐urban differences highlighting the need for targeted interventions to improve the health of pregnant individuals and their offspring.

ImportanceClinical trials guide evidence-based obstetrics and gynecology (OB-GYN) but often enroll nonrepresentative participants.ObjectiveTo characterize race and ethnicity reporting and representation in US OB-GYN clinical trials and their subsequent publications and to analyze the association of subspecialty and funding with diverse representation.Design and SettingCross-sectional analysis of all OB-GYN studies registered on ClinicalTrials.gov (2007-2020) and publications from PubMed and Google Scholar (2007-2021). Analyses included logistic regression controlling for year, subspecialty, phase, funding, and site number. Data from 332 417 studies were downloaded. Studies with a noninterventional design, with a registration date before October 1, 2007, without relevance to OB-GYN, with no reported results, and with no US-based study site were excluded.ExposuresOB-GYN subspecialty and funder.Main Outcomes and MeasuresReporting of race and ethnicity data and racial and ethnic representation (the proportion of enrollees of American Indian or Alaskan Native, Asian, Black, Latinx, or White identity and odds of representation above US Census estimates by race and ethnicity).ResultsAmong trials with ClinicalTrials.gov results (1287 trials with 591 196 participants) and publications (1147 trials with 821 111 participants), 662 (50.9%) and 856 (74.6%) reported race and ethnicity data, respectively. Among publications, gynecology studies were significantly less likely to report race and ethnicity than obstetrics (adjusted odds ratio [aOR], 0.54; 95% CI, 0.38-0.75). Reproductive endocrinology and infertility trials had the lowest odds of reporting race and ethnicity (aOR, 0.14; 95% CI, 0.07-0.27; reference category, obstetrics). Obstetrics and family planning demonstrated the most diverse clinical trial cohorts. Compared with obstetric trials, gynecologic oncology had the lowest odds of Black representation (ClinicalTrials.gov: aOR, 0.04; 95% CI, 0.02-0.09; publications: aOR, 0.06; 95% CI, 0.03-0.11) and Latinx representation (ClinicalTrials.gov: aOR, 0.05; 95% CI, 0.02-0.14; publications: aOR, 0.23; 95% CI, 0.10-0.48), followed by urogynecology and reproductive endocrinology and infertility. Urogynecology (ClinicalTrials.gov: aOR, 0.15; 95% CI, 0.05-0.39; publications: aOR, 0.24; 95% CI, 0.09-0.58) had the lowest odds of Asian representation.Conclusions and RelevanceRace and ethnicity reporting and representation in OB-GYN trials are suboptimal. Obstetrics and family planning trials demonstrate improved representation is achievable. Nonetheless, all subspecialties should strive for more equitably representative research.

There is variation in postpartum opioid use by prescriber characteristics that cannot be explained by patient or birth factors. Thus, our objective was to evaluate nursing training, clinical practices, and perspectives on opioid use for postpartum pain management.In this survey study, postpartum bedside nurses at a single, large academic center were asked about training, factors influencing clinical decisions, and viewpoints regarding pain management and opioid use. Findings were summarized using descriptive analyses.A total of 92 nurses completed the survey. A majority (77%) reported having received some formal training on opioid use for pain management. About a quarter (25.7%) felt their training was not adequate. Regarding clinical practices, the majority (71% and 70%, respectively) reported that "routine habit" and "patient preference" most influenced the type and amount of pain medication they administered. Finally, nurses' perspectives on pain management demonstrated a wide range of beliefs. Most nurses strongly agreed with the importance of maximizing nonopioid pain medication before opioid administration. The majority agreed that patient-reported pain score is important to consider when deciding to administer opioids. Conversely, most nurses disagreed that patients should be encouraged to endure as much pain as possible before using an opioid. Similarly, beliefs about the reliability of use of vital signs in assessing pain intensity varied widely.Bedside nurses rely on routine habits, patient preference, and patient-reported pain score when administering opioids for postpartum pain management. Increased training opportunities to improve consistency and standardization of opioid administration may be beneficial.

BACKGROUND: We describe trends in prevalence and identify factors associated with Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), syphilis, and Trichomonas vaginalis (TV) diagnosed in pregnancy among US people with human immunodeficiency virus (PWH) and evaluate associations of sexually transmitted infections (STIs) with preterm birth (PTB). METHODS: We included pregnant PWH enrolled in the Surveillance Monitoring for ART Toxicities dynamic cohort of the Pediatric HIV/AIDS Cohort Study network who delivered between 2010 and 2019. Multivariable log-binomial or Poisson generalized estimating equation models were used to estimate the association of calendar year with each STI, controlling for confounders; the association of demographic and clinical factors with each STI; and the association of each STI with PTB. RESULTS: The sample included 2241 pregnancies among 1821 PWH. Median age at delivery was 29.2 years; 71% of participants identified as Black or African American. STI prevalence was: CT 7.7%, NG 2.3%, syphilis 2.4%, and TV 14.5%; 30% had unknown TV status. There were no temporal changes in STI prevalence. Younger age and initial HIV viral load ≥400 copies/mL were associated with increased risk of CT, NG, and TV. Recreational substance use was a risk factor for NG, syphilis, and TV. No STI was associated with PTB. CONCLUSIONS: Unlike nationwide trends, no changes in STI prevalence during the study period were observed. The large proportion with unknown TV status underscores the need for increased adherence to screening guidelines. STIs diagnosed during pregnancy in PWH were not associated with risk of PTB.

Our objective was to assess the association between the nurse providing bedside care and women's postpartum opioid use.Retrospective study of all women who birthed at a single center (December 2015 to November 2016). Patient, prescriber, and clinical data were abstracted. The postpartum nurse and total opioid use during the first 12-hour postpartum shift after birth were determined. A high amount of opioid use was defined as morphine milligram equivalents greater than or equal to 90% for this population (stratified by vaginal and cesarean births). A logistic regression model was fit with covariates entered in a step-wise manner to identify the extent to which individual nurses were associated with a greater likelihood of high opioid use by establishing one model in which the only covariate was nurse (model 1) and assessing whether the addition of patient (model 2), birth (model 3), and prescriber factors (model 4) altered the association. Kendall rank correlation assessed rank changes between models.Of the 8376 and 2957 women who had vaginal and cesarean births, 17.9% and 10.2%, respectively, had high opioid use. In the vaginal cohort, women cared for by 46 of 200 nurses were significantly less likely to have high opioid use. Following adjustment, patients cared for by 53 of 200 bedside nurses (model 4) had significantly lower odds of having high opioid use. The rank order of nurses, with respect to the likelihood of opioid use, remained similar after adjustment for patient, birth, and prescriber factors (Τ = 0.84). Findings were similar for the cesarean cohort: 35 of 113 nurses were associated with a significantly lower likelihood of their patients having high opioid use, and the rank order remained similar after covariate adjustment (Τ = 0.78).There is significant variation in postpartum women's opioid use based on the nurse that is not explained by patient, birth, or prescriber factors.

Women who experience adverse pregnancy outcomes (APO) are at increased risk for cardiovascular disease (CVD); however, their knowledge of CVD risk is not well characterized. We aimed to evaluate knowledge and perception of CVD risk in young women and to determine whether these factors differ based on experience of an APO.We conducted a cross-sectional study among women with a recent live birth at an urban medical center. Knowledge and perception of CVD risk were assessed through a self-administered online survey adapted from the American Heart Association Survey of Women's CVD Awareness.Of 5612 individuals contacted between 3/1/21 and 4/18/21, 714 completed the survey; the mean (SD) age was 34 (4) years and 25% reported an APO. While 62% of respondents identified CVD as the leading cause of death in women, there was no significant difference in CVD knowledge scores between participants who reported experiencing an APO and those who did not (6.9 vs 6.8 out of 10;Gaps remain in knowledge of CVD risk among young women, particularly after an APO. The peripartum period may represent a unique opportunity for targeted education when healthcare engagement is high.

Background: Mobile health (mHealth) technology that addresses diabetes mellitus in pregnancy has the potential to improve maternal and child health while diminishing socioeconomic and racial disparities. Little is known about health literacy, electronic health literacy, or patient characteristics that contribute to increased mHealth use. In this pilot study, we aimed to examine patient factors associated with user engagement with a novel app for diabetes support during pregnancy. Method: Low-income pregnant individuals with gestational or type 2 diabetes mellitus were recruited for a 2-week usability assessment of a novel mHealth smartphone application, “SweetMama,” designed to improve diabetes care. This analysis of user characteristics was a pilot assessment of data from the usability study phase. Participants completed assessments of patient health literacy, electronic health literacy, diabetes self-efficacy, and activation. User metrics (eg, sessions and total duration of use) were evaluated by participant characteristics. Descriptive analyses were conducted to assess outcomes with respect to patient’s clinical history, health literacy, electronic health literacy, diabetes self-efficacy, and activation. Results: Twenty-two diverse, low-income pregnant patients with either gestational or type 2 diabetes engaged with SweetMama for 14 days. Participants with gestational diabetes had greater mean minutes of use per session and mean total duration of use than those with type 2 diabetes. Participants with greater electronic health literacy, lower patient activation, and greater self-efficacy demonstrated greater total duration of use. No user metrics differed significantly by participant general health literacy. Conclusions: Findings of this pilot study suggest engagement with a novel mHealth app for diabetes support during pregnancy varied by baseline behavioral and clinical characteristics. Results could indicate that digital health literacy better differentiates engagement patterns than general health literacy.

To establish whether administration of antenatal late preterm steroids to pregnant people with diabetes resulted in higher risk of neonatal hypoglycemia.This is a retrospective cohort study of individuals with pre-gestational or gestational diabetes admitted between 34 0/7-36 6/7 weeks' gestation before and after introduction of an antenatal late preterm steroids protocol. The primary outcome was any neonatal blood glucose ≤ 60 mg/dL in the first 24 h of life.Of 123 mother-neonate pairs, 52.8% (N = 65) delivered during the post-protocol period; 75.4% of those (N = 49) received late preterm steroids. 59.7% (N = 34) of the pre-protocol neonates and 81.5% (N = 53) of the post-protocol neonates had hypoglycemia (p = 0.008). After controlling for gestational age at delivery and mode of delivery, neonates in the post-protocol group had increased odds of hypoglycemia (adjusted odds ratio 2.96, 95% confidence interval 1.29-6.82).Neonates born to mothers with diabetes who received late preterm corticosteroids experienced greater odds of hypoglycemia.
