Objective Dispositional optimism (DO) is an understudied transdiagnostic resilience factor among peripartum individuals. Low DO is associated with increased fear and pain in labor and increased rates of emergent cesarean delivery, but it is unknown whether DO is associated with perceived control over the labor process. Study Design This a planned secondary analysis of a prospective observational cohort of term parturients (n = 164) who were recruited in July and August 2021 during their delivery hospitalization at a single, tertiary medical center. Participants completed a baseline demographic survey prior to delivery and then completed evaluations of DO (Revised Life-Orientation Test [LOT-R]) and control over the labor process (Labor Agentry Scale [LAS]) during their postpartum hospitalization. DO was dichotomized into low and high by score of ≤14 or >14 on LOT-R, respectively, and labor agentry scores were compared between groups. Maternal demographics, pregnancy, and delivery characteristics were compared by DO status. Multivariable regression was performed, adjusting for known confounders (induction, labor analgesia, and mode of delivery). Results Demographic, pregnancy, and neonatal characteristics were similar between those with low compared with high DO. People with low DO had significantly higher rates of cesarean section (44 vs. 24%, p = 0.02) and overall had lower LAS scores (139.4 vs. 159.4, p Conclusion People with low DO had significantly lower perceived control over their labor, even after controlling for differences in mode of delivery. Interventions to alter DO may be an innovative way to improve birth experience and its associated perinatal mental health morbidities. Key Points

Background Unplanned operative delivery is associated with postpartum depression (PPD), but the mechanism is unknown. We aimed to assess the sense of control over labor for those who had unplanned delivery (unplanned cesarean or operative vaginal delivery: uCD/OVD) versus spontaneous vaginal delivery (SVD).Methods Secondary analysis of a cross-sectional survey study of term patients admitted for delivery at a tertiary center. After delivery, patients completed the Labour Agentry Scale (LAS), a validated tool to assess perceived control over labor and birth. Demographics, obstetric and neonatal outcomes and LAS scores were compared between patients who underwent uCD/OVD versus SVD. Multivariable logistic regression to assess the relationship between uCD/OVD and LAS score controlling for confounders that differed in the bivariate analysis.Results Of the 149 patients, 50 (33.6%) underwent uCD/OVD. There were no differences in maternal age, race/ethnicity, insurance status or education level between those who had uCD/OVD versus SVD. Patients who had uCD/OVD had higher median body mass index (BMI) than those who had SVD (33.2 vs 30.1 kg/m2, p = 0.03). There were no differences in rate of medical or psychiatric morbidity between groups. Additionally, there were no differences in reason for admission, however those who had uCD/OVD had significantly longer times to delivery than those who underwent SVD (22 vs 14 hrs, p Conclusions Even after accounting for length of labor, uCD/OVD is associated with a reduction in perceived control over labor, which may mediate the known increased risk of PPD. Further qualitative research is needed to examine how to better support patients’ wellbeing after uCD/OVD.

Objectives During obstetric hemorrhage, peripheral vasoconstriction maintains heart rate and blood pressure until compensatory mechanisms are overwhelmed and patients deteriorate rapidly. Real-time perfusion measurements could quantify vasoconstriction, improving early recognition of hemorrhage and facilitating early intervention to reduce morbidity and mortality. The AccuFlow device makes rapid, non-invasive, quantitative measurements of perfusion, but has not been studied for hemorrhage detection or used in surgical settings. This study evaluated feasibility, tolerability, and preliminary efficacy of the AccuFlow for assessment of blood loss at cesarean delivery (CD). Methods In this pilot study, sensors were applied to the wrist, forearm, bicep, and chest wall of 25 patients undergoing scheduled CD. Postoperatively, sensors were removed and patients rated the AccuFlow and the standard anesthesia monitoring equipment on a validated comfort rating scale for wearable computers (CRS). Blood loss was estimated by the surgical team (EBL) and calculated from change in hematocrit, weight, and height (CBL). CRS scores were compared via Wilcoxon signed ranks tests. Coefficients of correlation between sensor readings and CBL, and between EBL and CBL, were compared using Fisher’s R-to-z transformation. Results There were no safety events; no participants requested device removal. CRS ratings of the AccuFlow and the standard monitoring equipment were similar (7.2 vs. 8.8, p=0.25). Change in wrist perfusion from delivery to dressing placement was more strongly correlated with CBL than was EBL (R=−0.48 vs. R=0.087, p=0.03). Conclusions The AccuFlow sensor is well-tolerated and shows promise in detecting intrapartum hemorrhage, though larger studies are needed.

Laboratories offering cell-free DNA often reserve the right to share prenatal genetic data for research or even commercial purposes, and obtain this permission on the patient consent form. Although it is known that nonpregnant patients are often reluctant to share their genetic data for research, pregnant patients' knowledge of, and opinions about, genetic data privacy are unknown.We investigated whether pregnant patients who had already undergone cell-free DNA screening were aware that genetic data derived from cell-free DNA may be shared for research. Furthermore, we examined whether pregnant patients exposed to video education about the Genetic Information Nondiscrimination Act-a federal law that mandates workplace and health insurance protections against genetic discrimination-were more willing to share cell-free DNA-related genetic data for research than pregnant patients who were unexposed.In this randomized controlled trial (ClinicalTrials.gov Identifier: NCT04420858), English-speaking patients with singleton pregnancies who underwent cell-free DNA and subsequently presented at 17 0/7 to 23 6/7 weeks of gestation for a detailed anatomy scan were randomized 1:1 to a control or intervention group. Both groups viewed an infographic about cell-free DNA. In addition, the intervention group viewed an educational video about the Genetic Information Nondiscrimination Act. The primary outcomes were knowledge about, and willingness to share, prenatal genetic data from cell-free DNA by commercial laboratories for nonclinical purposes, such as research. The secondary outcomes included knowledge about existing genetic privacy laws, knowledge about the potential for reidentification of anonymized genetic data, and acceptability of various use and sharing scenarios for prenatal genetic data. Eighty-one participants per group were required for 80% power to detect an increase in willingness to share data from 60% to 80% (α=0.05).A total of 747 pregnant patients were screened, and 213 patients were deemed eligible and approached for potential study participation. Of these patients, 163 (76.5%) consented and were randomized; one participant discontinued the intervention, and two participants were excluded from analysis after the intervention when it was discovered that they did not fulfill all eligibility criteria. Overall, 160 (75.1%) of those approached were included in the final analysis. Most patients in the control group (72 [90.0%]) and intervention (76 [97.4%]) group were either unsure about or incorrectly thought that cell-free DNA companies could not share prenatal genetic data for research. Participants in the intervention group were more likely to incorrectly believe that their prenatal genetic data would not be shared for nonclinical purposes than participants in the control group (28.8% in the control group vs 46.2% in the intervention; P=.03). However, video education did not increase participant willingness to share genetic data in multiple scenarios. Non-White participants were less willing than White participants to allow sharing of genetic data specifically for academic research (P.001).Most participants were unaware that their prenatal genetic data may be used for nonclinical purposes. Pregnant patients who were educated about the Genetic Information Nondiscrimination Act were not more willing to share genetic data than those who did not receive this education. Surprisingly, video education about the Genetic Information Nondiscrimination Act led patients to falsely believe that their data would not be shared for research, and participants who identified as racial minorities were less willing to share genetic data. New strategies are needed to improve pregnant patients' understanding of genetic privacy.

As induction of labor (IOL) becomes more common, hospitals must adjust to accommodate longer length of stays on labor and delivery. An alternative to reduce the length of time spent on labor and delivery during an IOL is to perform cervical ripening on an antepartum unit. However, this may affect patient satisfaction and knowledge about the birthing process. This study aimed to evaluate whether cervical ripening conducted in an antepartum unit, rather than on a labor and delivery unit, was associated with changes in patient satisfaction with birth experience and baseline knowledge about IOL. Additionally, the study aimed to understand how patients would prefer to receive education on the IOL process.This prospective observational study recruited English and Spanish-speaking patients at or after 39 weeks and 0 days gestation who were admitted for IOL. Consenting patients completed a preliminary survey containing sociodemographic and obstetric information as well as a previously validated survey on IOL knowledge on admission. Within 48 h of delivery, patients completed a follow-up survey including a validated birth satisfaction survey, the Birth Satisfaction Scale-Revised, and questions eliciting their preferred IOL education method. Data analyses compared patients who were admitted to antepartum for IOL to those admitted directly to labor and delivery. Multivariate analyses adjusted for sociodemographic and obstetric differences between the two groups. The primary outcomes were scores on the Birth Satisfaction Scale-Revised and on a test examining IOL knowledge. Secondary outcomes included preferred method of IOL education, obstetric outcomes, and neonatal outcomes.A total of 277 eligible patients were approached from October 2020 to March 2021. Of the 216 (78%) that consented, 159 (74%) completed the follow-up survey and were subsequently included in this analysis. Individuals admitted directly to antepartum (Unit of admission for IOL is not associated with satisfaction with birth experience but is associated with patient knowledge of IOL. This suggests that IOL may be initiated in less acute units than labor and delivery without altering birth experience and may potentially allow for increased patient knowledge. Additionally, IOL checklists or technology-based education may help to further increase patient knowledge about IOL.

Objective This study aimed to evaluate whether transient fetal growth restriction (FGR) that resolves prior to delivery confers a similar risk of neonatal morbidity as uncomplicated FGR that persists at term. Study Design This is a secondary analysis of a medical record abstraction study of singleton live-born pregnancies delivered at a tertiary care center between 2002 and 2013. Patients with fetuses that had either persistent or transient FGR and delivered at 38 weeks or later were included. Patients with abnormal umbilical artery Doppler studies were excluded. Persistent FGR was defined as estimated fetal weight (EFW) Results Of 777 patients studied, 686 (88%) had persistent FGR and 91 (12%) had transient FGR. Patients with transient FGR were more likely to have a higher body mass index, gestational diabetes, diagnosed with FGR earlier in pregnancy, have spontaneous labor, and deliver at later gestational ages. There was no difference in the composite neonatal outcome (relative risk = 1.03, 95% confidence interval [CI] 0.72, 1.47) for transient versus persistent FGR after adjusting for confounders (adjusted relative risk = 0.79, 95% CI 0.54, 1.17). There were no differences in cesarean delivery or delivery complications between groups. Conclusion Neonates born at term after transient FGR do not appear to have differences in composite morbidity compared with those where uncomplicated FGR persists at term. Key Points

Objective Pregnancies complicated by perinatal mood disorders or a history of mental health disorder are at increased risk for complications including postpartum depression/anxiety. Patients' perceived control over childbirth is known to be an important factor for development of postpartum depression/anxiety. It is unclear whether women with preexisting and/or current depression and/or anxiety have different perceptions of control during childbirth compared with those without these comorbidities. This study aimed to evaluate the association between a current and/or prior diagnosis of depression and/or anxiety and scores on the Labour Agentry Scale (LAS), a validated tool evaluating patient's experience of control over their labor and delivery. Study Design This is a cross-sectional study of nulliparous patients admitted at term to a single center. Participants completed the LAS after delivery. A trained researcher performed detailed chart reviews for all participants. Participants were identified as having a current or historical diagnosis of depression/anxiety by self-report confirmed by chart review. Scores on the LAS were compared between those with versus without a diagnosis of depression/anxiety prior to admission for delivery. Results A total of 73 (44.8%) of the 149 participants held a current and/or prior diagnosis of depression and/or anxiety. Baseline demographics were similar between those with and without depression/anxiety. Mean scores on the LAS (range: 91–201) were significantly lower for those with depression/anxiety than those without a prior diagnosis (150.0 vs. 160.5, p Conclusion Participants with a current and/or prior diagnosis of depression and/or anxiety scored lower on the LAS as compared with those without psychiatric diagnoses. Patients with psychiatric diagnoses may benefit from increased education and support during childbirth. Key Points

Objective This study aimed to evaluate the association of induction method on delivery mode in pregnancies complicated by oligohydramnios with and without fetal growth restriction (FGR). Study Design This was a secondary analysis of a National Institutes of Health funded retrospective cohort study of singleton deliveries at a tertiary-care hospital between 2002 and 2013 with diabetes, mild hypertension, and/or FGR. Chart abstraction was performed by trained research nurses. Patients with a diagnosis of fetal oligohydramnios with and without FGR were identified. Our analytic cohort was further stratified into three groups per initial induction agent: prostaglandins (PGEs) alone, PGE plus mechanical ripening, or oxytocin only. Primary outcome was mode of delivery. Secondary outcomes included indications for cesarean delivery and neonatal morbidity. Results Out of 4,929 patients in the original database, 546 subjects with fetal oligohydramnios were identified; of these, 270 were induced and included for analysis. Outcomes were compared between 171 patients who had fetuses with isolated oligohydramnios and 99 patients who had fetuses with oligohydramnios and FGR. There were no significant differences in demographic characteristics between the groups. Patients with fetuses with isolated oligohydramnios had similar rates of spontaneous vaginal delivery (SVD) when PGEs were used (n = 44/79, 55.7% PGE alone, n = 44/76, 57.9% PGE with mechanical ripening) and when they were not used (n = 5/13, 38.5% oxytocin alone; p = 0.43). Similarly, the majority of patients in both cohorts underwent SVD regardless of induction method (n = 30/44, 68.2% PGE alone, n = 30/44, 68.2% PGE with mechanical ripening, and n = 6/10, 60% oxytocin alone; p = 0.90). There was no significant difference in composite neonatal morbidity. Conclusion In patients with fetuses with oligohydramnios with and without FGR, most patients delivered by SVD regardless of induction method. In this population, PGE use was associated with a high chance of SVD in patients with fetuses with suspected placental insufficiency regardless of the presence of absence of FGR. Key Points

Although successful trial of labor after cesarean (TOLAC) resulting in vaginal birth after cesarean (VBAC) can lead to improved maternal and neonatal outcomes, an unsuccessful TOLAC is associated with increased risk of uterine rupture, higher blood loss, and increased risk of infection. Data remain limited in terms of whether differences in gestational age of patients who attempt TOLAC affect maternal morbidity. Out objective was to examine the association between gestational age and maternal adverse outcomes in women undergoing trial of labor after cesarean.This population-based cross-sectional study used birth data from the U.S. National Vital Statistics from 2014 to 2018. Women with liveborn singleton gestation who underwent TOLAC at 23 - 41 weeks' gestation were included in the analytic population. The primary outcome was a composite of maternal adverse outcomes: admission to the intensive care unit, blood transfusion, uterine rupture, or unplanned hysterectomy. Secondary outcomes were individual measures within the primary composite outcome. Outcomes were compared between patients who underwent TOLAC at term (37-41 weeks gestational age) and those who underwent TOLAC at preterm (23-36 weeks gestational age). Multivariable analyses adjusted for demographic and obstetric differences between the two groups.455,284 patients met inclusion criteria for the study; 39,589 (8.7%) were at a preterm gestational age (GA) and 415,695 (91.3%) were at a term GA. The overall composite maternal adverse outcome was significantly higher for patients undergoing TOLAC at preterm GA (12.0 per 1,000 live births) compared to term GA (8.0 per 1,000 live births; aRR1.42; 95% CI 1.29-1.56). Among individual conditions within the primary composite outcome, preterm gestational age was associated with increased risk of admission to the intensive care unit, blood transfusion, and unplanned hysterectomy.In patients who underwent TOLAC, preterm gestational age was associated with increased risk of adverse maternal outcomes.

To identify whether risk factors for respiratory distress syndrome (RDS) differ between early-term and full-term births.This is a secondary analysis of a large NIH-funded retrospective cohort study including patients who delivered at a tertiary-care obstetric hospital between January 2002 and March 2013 with comorbid diabetes, hypertensive disorders, and/or fetal growth restriction (FGR). Pregnancies complicated by severe preeclampsia and multifetal gestations were excluded. Maternal characteristics, delivery information, and neonatal information were abstracted by trained clinicians blinded to the comorbidity leading to study inclusion. In this secondary analysis of the infant health outcomes of pregnancies with one or more of the qualifying conditions, risk factors for RDS among neonates born early term (37w0d-38w6d gestation) were compared to risk factors for RDS among full-term neonates (39w0d-40w6d).Among 10,532 singleton newborns, there were 99 cases of early-term RDS (0.94%) and 95 cases of full-term RDS (0.90%). Maternal demographics were similar between those with and without RDS in both groups. Among early-term infants, lower gestational age, presence of meconium, non-spontaneous labor, and cesarean delivery were positively associated with RDS, whereas hypertensive disorders, diabetes, FGR, and many other comorbid delivery conditions were not. The strongest risk factor for RDS among early-term infants was delivery via cesarean (RR 1.98, 95% CI 1.31, 3.01). Among full-term neonates, cesarean delivery was also positively associated with RDS, although presence of meconium, chorioamnionitis, and endometritis were all stronger risk factors with RRs2.0.In this cohort of high-risk term deliveries, maternal demographics and comorbidities were found not to be associated with increased risk for RDS, but novel risk factors for RDS after 37 weeks' gestation - chorioamnionitis and endometritis - were identified. A focus on preventing infectious comorbidities may help reduce incidence of RDS at full-term.Key PointsRDS risk factors vary by gestational age.Novel risk factors for RDS at full-term identified.Intrauterine inflammation associated with RDS at term.

The first class of virtually interviewed maternal-fetal medicine fellows has matriculated into their training programs.This study aimed to evaluate the impact of virtual interviews on the outcomes of the National Resident Matching Program within our subspecialty. We assessed maternal-fetal medicine fellowship program directors' experience with their fellows who interviewed virtually as compared with experience with the previous year's fellows who interviewed in-person. In addition, we evaluated program directors' satisfaction with the virtual interview process and their preferred mode of interviewing for future cycles.A cross-sectional online survey was distributed through the Society for Maternal-Fetal Medicine to all maternal-fetal medicine fellowship program directors on October 26, 2021, approximately 4 months after the first virtually interviewed fellow matriculated into the training program. Program directors were asked to provide information about their National Resident Matching Program rank list between their final in-person and first virtual years. Program directors were asked to evaluate their experience with their fellow 4 months into the first year of fellowship compared with their expectations based on their virtual interview, and their experience at that same point in fellowship of their last fellow who interviewed in-person. For all questions, in programs with1 fellow per year, program directors were asked to answer the questions for the fellow ranked highest on their National Resident Matching Program rank list for each year. Survey data were collected anonymously and stored securely. Descriptive statistics and bivariate analyses were performed to compare groups, all tests were 2-sided, and the significance level was set at P.05.A total of 80 of 98 (81.6%) program directors responded. There was no difference in the position of the matched fellow on the program's National Resident Matching Program rank list between candidates interviewed in-person and candidates interviewed virtually. There was also no difference in the number of programs that took an internal or external candidate outside of the National Resident Matching Program match process or that did not fill their fellowship positions. Program directors reported no difference between fellows interviewed virtually and those interviewed in-person in meeting interview-based performance expectations with regard to clinical capabilities (P=.67), technical skills (P=.96), research potential or experience (P=.54), professionalism and ability to be a team player (P=.72), and compatibility with the division and fellowship program (P=.67). Program directors' overall experience with virtual interviews was favorable: 70 (95.8%) program directors reported that the virtual interview experience was better than expected, slightly better than expected, or as expected. In future years, most program directors favored ongoing exclusively virtual interviewing (n=41; 56.2%) or a hybrid of virtual and in-person interviews (n=27; 37.0%). Only 5 (6.9%) reported a desire to return to exclusively in-person interviewing.Maternal-fetal medicine fellowship program directors did not identify a difference in National Resident Matching Program results between fellows interviewed virtually and those interviewed in-person. Furthermore, there was no difference between these fellows in meeting interview-based expectations in the first year of the training program. Most program directors found the virtual interview process to be effective and support ongoing virtual interviews.

OBJECTIVE: Antenatal depression (AD) is frequently cited as a risk factor for cesarean delivery (CD) with limited supporting data. STUDY DESIGN: We utilized 2016–2018 data from the Pregnancy Risk Assessment Monitoring System (PRAMS) survey for the state of Rhode Island. Nulliparous women who reported AD (n=242) were compared to women who did not (n=1,081). Maternal demographics, pregnancy and delivery characteristics were compared by AD status using population-weighted bivariable analyses and multivariable logistic regression. RESULTS: 17.7% reported AD, and 34% underwent CD. There was no difference in CD based on reported AD status (aOR 1.04; 95% CI 0.69, 1.56). However, there were significant differences between those reporting AD compared to those who did not: less education, more public insurance, use of Women, Infants and Children (WIC) benefits, tobacco use, and pre-gestational hypertension/diabetes. CONCLUSION: In this large, population-based, state representative sample, we found no difference in CD among recently delivered nulliparous women with and without AD.
