Using data from the San Diego Birth Center Study that enrolled underserved women between 1994 and 1996, we examined demographic, sociobehavioral, and medical predictors of hospital transfer in a group of women who intended to deliver at a freestanding birth center. Of the 1808 women, 34.6% transferred to the hospital antenatally and 19.6% transferred during labor, while 45.7% delivered at the birth center. Compared with multiparous women who had never had a cesarean and never had a previous hospital delivery, nulliparous women were 2.0 times more likely (95% confidence interval [CI], 1.4-2.7), multiparous women with a previous cesarean were 2.6 times more likely (95% CI, 1.7-3.8), and women without a previous cesarean but who had a previous hospital delivery were 2.1 times more likely (95% CI, 1.5-3.0) to transfer after adjusting for other predictors of transfer. Nulliparity, cesarean history and having a previous hospital delivery were among the strongest predictors of a hospital transfer even after adjusting for demographic, sociobehavioral, and other medical conditions. Understanding predictors of transfer may assist practitioners, patients, and policy makers in considering the appropriateness of individuals for birth center delivery or to target further education to reduce nonmedical transfers.

Although vaginal delivery has long been assumed to be the preferred route of delivery in women who have not had a prior cesarean delivery, some have recently advocated that women be offered the option of elective, primary cesarean delivery in all pregnancies. Available outcome data, however, do not permit ready comparison of these alternate plans for delivery. Important maternal outcomes include short-term complications such as death, bleeding, infection, and damage to pelvic organs as well as long-term effects on future pregnancies, fecal and urinary incontinence, and pelvic organ prolapse. Important neonatal outcomes include asphyxic and traumatic birth injury, infection, respiratory complications, and stillbirth. To weigh the relative merits of elective primary cesarean delivery and a trial of labor, a randomized controlled trial is needed. Such a trial would be both ethical and feasible.

Objective: Increased leukocyte count is a marker of inflammation that has been associated with the development of type 2 diabetes in prospective studies. Although gestational diabetes mellitus (GDM) and type 2 diabetes share certain pathophysiological mechanisms, few studies have examined inflammation and risk of GDM.Research Design and Methods: We prospectively examined routine leukocyte counts collected at the first prenatal visit in a cohort of 2,753 nulliparous euglycemic women, 98 (3.6%) of whom were later diagnosed with GDM. Subjects were divided into quartiles of leukocyte count, and the results of third-trimester glucose screening tests and the incidence of GDM among these quartiles were compared. Logistic regression was used to calculate univariate and multivariable-adjusted relative risks (RRs) of GDM according to leukocyte quartiles.Results: Leukocyte counts were increased among women who subsequently developed GDM compared with those who remained free of GDM (10.5 +/- 2.2 vs. 9.2 +/- 2.2 x 10(3) cells/ml; P < 0.01). There was a linear increase in postloading mean glucose levels (P for trend <0.01), the area under the glucose tolerance test curves (P for trend <0.01), and the incidence of GDM (quartile 1, 1.1; quartile 2, 2.5; quartile 3, 4.2; and quartile 4, 6.4%; P for trend <0.01) with increasing leukocyte quartiles. In the multivariable-adjusted analysis, the linear trend in the RR of GDM with increasing leukocyte quartiles remained statistically significant (quartile 1, reference; quartile 2, RR 2.3 [95% CI 0.9-5.7]; quartile 3, 3.3 [1.4-7.8]; quartile 4, 4.9 [2.1-11.2]; P for trend <0.01).Conclusions: Increased leukocyte count early in pregnancy is independently and linearly associated with the results of GDM screening tests and the risk of GDM. Although overlap in the leukocyte count distributions precludes it from being a clinically useful biomarker, these data suggest that inflammation is associated with the development of GDM and may be another pathophysiological link between GDM and future type 2 diabetes.

The intrapartum assessment of fetal well-being presents a challenge to obstetricians, especially given contemporary concern for rising rates of both cesarean delivery and malpractice litigation.Several techniques may be used to evaluate the fetus during labor including direct analysis of fetal blood obtained from via scalp sampling.Although blood specimens may be safely obtained from the fetal scalp during labor, the need for such sampling has been dramatically reduced in recent years by the use of other non-invasive tests such as fetal scalp stimulation or vibroacoustic stimulation.

OBJECTIVE: We sought to characterize practices and attitudes of maternal-fetal medicine (MFM) and fetal care pediatric (FCP) specialists regarding fetal abnormalities. STUDY DESIGN: This was a self-administered survey of 434 MFMs and FCPs (response rate: MFM 60.9%; FCP 54.2%). RESULTS: For Down syndrome (DS), congenital diaphragmatic hernia (CDH), spina bifida: MFMs were more likely than FCPs to support termination (DS 52% vs 35%, P < .001; CDH 49% vs 36%, P < .001; spina bifida 54% vs 35%, P < .001), and consider offering termination options as highly important (DS 90% vs 70%, P < .001; CDH 88% vs 69%, P < .001; spina bifida 88% vs 70%, P < .001). For DS only, MFMs were less likely than FCPs to think that pediatric specialist consultation should be offered prior to a decision regarding termination (54% vs 75%, P < .001). MFMs reported report higher termination rates among patients only for DS (DS 51% vs 21%, P < .001). CONCLUSION: MFM and FCP specialists' counseling attitudes differ for fetal abnormalities.

Background: Toxicology testing is frequently used as a means of gathering objective data about substance use in pregnancy, but little is known about the clinical utility of testing in the peripartum setting., Objective: This study aimed to characterize the utility of obtaining maternal-neonatal dyad toxicology testing at the time of delivery., Study Design: We performed a retrospective chart review of all deliveries in a single healthcare system in Massachusetts between 2016 and 2020, and identified deliveries with either maternal or neonatal toxicology testing at delivery. An unexpected result was defined as a positive test for a nonprescribed substance that was not known on the basis of clinical history, self-report, or previous toxicology testing within a week of delivery, excluding results for cannabis. We evaluated the characteristics of maternal-infant dyads with unexpected positive results, unexpected positive results by rationale for testing, changes in clinical management after an unexpected positive test, and maternal outcomes in the year after delivery using descriptive statistics., Results: Of the 2036 maternal-infant dyads with toxicology tests performed during the study period, there were 80 (3.9%) with an unexpected positive result. Diagnosis of substance use disorder with active use in the last 2 years was the clinical rationale for testing that yielded the greatest number of unexpected positive results (10.7% of total tests ordered for this rationale). Inadequate prenatal care (5.8%), maternal use of medication for opioid use disorder (3.8%), maternal medical indications such as hypertension or placental abruption (2.3%), history of substance use disorder in remission (1.7%), or maternal cannabis use (1.6%) yielded lower rates of unexpected results compared with a recent substance use disorder (within the last 2 years). Solely on the basis of findings from unexpected test results, 42% of dyads were referred to child protective services, 30% of dyads had no documentation of maternal counseling during delivery hospitalization, and 31% did not receive breastfeeding counseling after an unexpected test; 22.8% had monitoring for neonatal opioid withdrawal syndrome. Postpartum, 26 (32.5%) were referred to substance use disorder treatment, 31 (38.8%) attended a postpartum mental health visit, and only 26 (32.5%) attended a postpartum visit. Fifteen individuals (18.8%) were readmitted in the year after delivery, all for substance-related medical complications., Conclusion: Unexpected positive toxicology results at delivery were uncommon, particularly when tests were sent for frequently used clinical rationales for testing, suggesting a need to revisit guidelines surrounding appropriateness of indications for toxicology testing. The poor maternal outcomes in this cohort highlight a missed opportunity for maternal connection to counseling and treatment in the peripartum period., (Copyright © 2023 Elsevier Inc.

Human herpesviruses 6A (HHV-6A) and human herpesvirus 6B (HHV-6B)-collectively, HHV-6A/B-are recently-discovered but ancient human viruses. The vast majority of people acquire one or both viruses, typically very early in life, producing an ineradicable lifelong infection. The viruses have been linked to several neurological, pulmonary and hematological diseases. In early human history, the viruses on multiple occasions infected a germ cell, and integrated their DNA into a human chromosome. As a result, about 1% of humans are born with the full viral genome present in every cell, with uncertain consequences for health. HHV-6A may play a role in 43% of cases of primary unexplained infertility. Both the inherited and acquired viruses may occasionally trigger several of the factors that are important in the pathogenesis of preeclampsia. Transplacental infection occurs in 1-2% of pregnancies, with some evidence suggesting adverse health consequences for the child. While emerging knowledge about these viruses in reproductive diseases is not sufficient to suggest any changes in current practice, we write this review to indicate the need for further research that could prove practice-changing., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Komaroff, Rizzo and Ecker.)

Background: Thrombotic thrombocytopenic purpura (TTP) is a rare but serious complication in pregnancy that places the mother and fetus at high risk for morbidity and mortality. This case illustrates novel pregnancy complications associated with this rare medical condition., Case Presentation: A 31-year-old G3P0020 at 28 weeks and 1 day was admitted with severe thrombocytopenia and was ultimately diagnosed with TTP. With therapeutic plasma exchange (TPE), maternal status improved. At 28 weeks 6 days, however, non-reassuring fetal testing prompted cesarean delivery with placental abruption noted intraoperatively. Pathology examination confirmed placental abruption and also revealed multiple placental infarcts., Conclusion: While medical management of TTP can significantly improve the health of the mother, this case highlights the potential role of TTP in abruption and other placental pathology and thus, the need for close fetal surveillance throughout an affected pregnancy.

Objective: We sought to determine if hospital delivery volume was associated with a patient's risk for cesarean delivery in low-risk women., Study Design: This study retrospectively examines a cohort of 1 657 495 deliveries identified in the 2013 Nationwide Readmissions Database. Hospitals were stratified by delivery volume quartiles. Low-risk patients were identified using the Society for Maternal-Fetal Medicine definition (n=845 056). A multivariable logistic regression accounting for hospital-level clustering was constructed to assess the factors affecting a patient's odds for cesarean delivery., Results: The range of cesarean delivery rates was 2.4-51.2% among low-risk patients, and the median was 16.5% (IQR 12.8-20.5%). The cesarean delivery rate was higher in the top two-volume-quartile hospitals (17.4 and 18.2%) compared to the bottom quartiles (16.4 and 16.3%) (P<0.001). Hospital volume was not associated with a patient's odds for cesarean delivery after adjusting for patient and other hospital characteristics (P=0.188)., Conclusion: Hospital delivery volume is not an independent predictor of cesarean delivery in this population.

Background: Although many women with physical disabilities report poor quality reproductive health care, little research has addressed labor, delivery, and anesthesia experiences of these women. This study was conducted to explore these experiences in women with significant mobility disabilities., Methods: A qualitative descriptive study was conducted with 22 women from the United States who had delivered newborns within the prior 10 years. All had significant mobility disabilities. Two-hour, in-depth telephone interviews were conducted using a semistructured, open-ended interview protocol, which addressed many topics, including labor, delivery, and anesthesia experiences. We recruited most participants through social networks, interviewing women from 17 states. Conventional content analysis, facilitated by NVivo software, was used to identify major themes., Results: The mean age of women was 34.8 ± 5.3 years. Most women were white, college educated, and used wheeled mobility aids. Four key themes emerged from participants' narratives of laboring and giving birth with a disability. These included women's preferences for type of delivery, clinicians and some women expected no labor pain, fears prompting active advocacy, and positive experiences. As participants discussed their experiences with anesthesia, four additional themes were identified: importance of consultation with the anesthesia team, decisions about epidural/spinal vs general anesthesia, failed epidural with repeated efforts, and fear of injury related to anesthesia., Conclusions: The responses of women in this study suggest that there is need to make intrapartum care better for women with physical disabilities and to improve their experiences with labor, birth, and obstetric anesthesia care., (© 2017 Wiley Periodicals, Inc.)

Objective: To define the amount of opioid analgesics prescribed and consumed after discharge after cesarean delivery., Methods: We conducted a survey at six academic medical centers in the United States from September 2014 to March 2016. Women who had undergone a cesarean delivery were contacted by phone 2 weeks after discharge and participated in a structured interview about the opioid prescription they received on discharge and their oral opioid intake while at home., Results: A total of 720 women were enrolled; of these, 615 (85.4%) filled an opioid prescription. The median number of dispensed opioid tablets was 40 (interquartile range 30-40), the median number consumed was 20 (interquartile range 8-30), and leftover was 15 (interquartile range 3-26). Of those with leftover opioids, 95.3% had not disposed of the excess medication at the time of the interview. There was an association between a larger number of tablets dispensed and the number consumed independent of patient characteristics. The amount of opioids dispensed did not correlate with patient satisfaction, pain control, or the need to refill the opioid prescription., Conclusion: The amount of opioid prescribed after cesarean delivery generally exceeds the amount consumed by a significant margin, leading to substantial amounts of leftover opioid medication. Lower opioid prescription correlates with lower consumption without a concomitant increase in pain scores or satisfaction.

The visual system consists of two major subsystems, image-forming circuits that drive conscious vision and non-image-forming circuits for behaviors such as circadian photoentrainment. While historically considered non-overlapping, recent evidence has uncovered crosstalk between these subsystems. Here, we investigated shared developmental mechanisms. We revealed an unprecedented role for light in the maturation of the circadian clock and discovered that intrinsically photosensitive retinal ganglion cells (ipRGCs) are critical for this refinement process. In addition, ipRGCs regulate retinal waves independent of light, and developmental ablation of a subset of ipRGCs disrupts eye-specific segregation of retinogeniculate projections. Specifically, a subset of ipRGCs, comprising ~200 cells and which project intraretinally and to circadian centers in the brain, are sufficient to mediate both of these developmental processes. Thus, this subset of ipRGCs constitute a shared node in the neural networks that mediate light-dependent maturation of the circadian clock and light-independent refinement of retinogeniculate projections.

Background: Although growing numbers of women with mobility disability are becoming pregnant and desiring motherhood, relatively little is known about their pregnancy experiences or what they might recommend to other women with mobility disability contemplating pregnancy., Methods: Using a semistructured, open-ended interview protocol, we conducted 2-hour telephone interviews with 22 women who had a significant mobility disability before becoming pregnant and had delivered babies within the prior 10 years. We recruited most interviewees through online social networks. We used NVivo software to sort interview transcript texts and performed conventional content analyses to identify major themes., Results: Participants' mean ± standard deviation age was 34.8 ± 5.3 years; most were White, well-educated, and middle income and 18 used wheeled mobility aids. Recommendations for other women with mobility disability coalesced around five themes: recognizing the possibility of giving birth, advocacy and support, being informed, approaches toward obstetrical practitioners, and managing fears about losing custody of their child. Lacking information about what to expect during their pregnancy was a significant problem. Women got information about pregnancy from diverse sources, but questions arose about accuracy and relevance of this information to individual circumstances. Women urged their peers to advocate for their preferences and needs with obstetrical practitioners., Conclusions: Women with mobility disability who had delivered babies offered constructive advice for their peers who desire pregnancy. Increasing availability of accurate and relevant information about pregnancy among women with mobility disability is critically important, as is training obstetrical practitioners to provide patient-centered care to these women during pregnancy., (Copyright © 2016 Jacobs Institute of Women's Health.

Importance: Induction of labor is a frequently performed obstetrical intervention. It would thus be of great concern if reported associations between labor induction and offspring risk of autism spectrum disorders (ASD) reflected causal influence., Objective: To assess the associations of labor induction with ASD, comparing differentially exposed relatives (siblings and cousins discordant for induction)., Design, Setting, and Participants: Follow-up of all live births in Sweden between 1992 and 2005, defined in the Medical Birth Register. The register was linked to population registers of familial relations, inpatient and outpatient visits, and education records. Diagnoses of ASD were from 2001 through 2013, and data were analyzed in the 2015-2016 year., Exposures: Induction of labor., Main Outcomes and Measures: Autism spectrum disorders identified by diagnoses from inpatient and outpatient records between 2001 and 2013. Hazard ratios (HRs) quantified the association between labor induction and offspring ASD. In addition to considering a wide range of measured confounders, comparison of exposure-discordant births to the same woman allowed additional control for all unmeasured factors shared by siblings., Results: The full cohort included 1 362 950 births, of which 22 077 offspring (1.6%) were diagnosed with ASD by ages 8 years through 21 years. In conventional models of the full cohort, associations between labor induction and offspring ASD were attenuated but remained statistically significant after adjustment for measured potential confounders (HR, 1.19; 95% CI, 1.13-1.24). When comparison was made within siblings whose births were discordant with respect to induction, thus accounting for all environmental and genetic factors shared by siblings, labor induction was no longer associated with offspring ASD (HR, 0.99; 95% CI, 0.88-1.10)., Conclusions and Relevance: In this nationwide sample of live births we observed no association between induction of labor and offspring ASD within sibling comparison. Our findings suggest that concern for ASD should not factor into the clinical decision about whether to induce labor., Competing Interests: Disclosures: None reported.

This document builds upon recommendations from peer organizations and outlines a process for identifying maternal cases that should be reviewed. Severe maternal morbidity is associated with a high rate of preventability, similar to that of maternal mortality. It also can be considered a near miss for maternal mortality because without identification and treatment, in some cases, these conditions would lead to maternal death. Identifying severe morbidity is, therefore, important for preventing such injuries that lead to mortality and for highlighting opportunities to avoid repeat injuries. The two-step screen and review process described in this document is intended to efficiently detect severe maternal morbidity in women and to ensure that each case undergoes a review to determine whether there were opportunities for improvement in care. Like cases of maternal mortality, cases of severe maternal morbidity merit quality review. In the absence of consensus on a comprehensive list of conditions that represent severe maternal morbidity, institutions and systems should either adopt an existing screening criteria or create their own list of outcomes that merit review., (Copyright © 2016 American College of Obstetricians and Gynecologists, 409 12th Street, SW, PO Box 96920, Washington, DC 20090-6920.

Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth. These include, but are not limited to, nonmodifiable factors (eg, fetal sex, weight, plurality), potentially modifiable antepartum and intrapartum factors (eg, location of delivery, intent to intervene by cesarean delivery or induction for delivery, administration of antenatal corticosteroids and magnesium sulfate), and postnatal management (eg, starting or withholding and continuing or withdrawing intensive care after birth). Antepartum and intrapartum management options vary depending upon the specific circumstances but may include short-term tocolytic therapy for preterm labor to allow time for administration of antenatal steroids, antibiotics to prolong latency after preterm premature rupture of membranes or for intrapartum group B streptococci prophylaxis, and delivery, including cesarean delivery, for concern regarding fetal well-being or fetal malpresentation. Whenever possible, periviable births for which maternal or neonatal intervention is planned should occur in centers that offer expertise in maternal and neonatal care and the needed infrastructure, including intensive care units, to support such services. This document describes newborn outcomes after periviable birth, provides current evidence and recommendations regarding interventions in this setting, and provides an outline for family counseling with the goal of incorporating informed patient preferences. Its intent is to provide support and guidance regarding decisions, including declining and accepting interventions and therapies, based on individual circumstances and patient values., (Copyright © 2016 American College of Obstetricians and Gynecologists, 409 12th Street, SW, PO Box 96920, Washington, DC 20090-6920.

Objective: To characterize physiologic subtypes of gestational diabetes mellitus (GDM)., Research Design and Methods: Insulin sensitivity and secretion were estimated in 809 women at 24-30 weeks' gestation, using oral glucose tolerance test-based indices. In women with GDM (8.3%), defects in insulin sensitivity or secretion were defined below the 25th percentile in women with normal glucose tolerance (NGT). GDM subtypes were defined based on the defect(s) present., Results: Relative to women with NGT, women with predominant insulin sensitivity defects (51% of GDM) had higher BMI and fasting glucose, larger infants (birth weight z score 0.57 [-0.01 to 1.37] vs. 0.03 [-0.53 to 0.52], P = 0.001), and greater risk of GDM-associated adverse outcomes (57.6 vs. 28.2%, P = 0.003); differences were independent of BMI. Women with predominant insulin secretion defects (30% of GDM) had BMI, fasting glucose, infant birth weights, and risk of adverse outcomes similar to those in women with NGT., Conclusions: Heterogeneity of physiologic processes underlying hyperglycemia exists among women with GDM. GDM with impaired insulin sensitivity confers a greater risk of adverse outcomes., (© 2016 by the American Diabetes Association.

Background: Hospital readmissions are costly, frequent, and increasingly under public scrutiny. With increased financial constraints on the medical environment, understanding the drivers of unscheduled readmissions following gynecologic surgery will become increasingly important to value-driven care., Objective: The current study was conducted to identify risk factors for 30-day readmission following hysterectomy for benign and malignant indications., Study Design: A retrospective cohort study was conducted from 2008 through 2010 of all nongravid hysterectomies at a single tertiary care academic medical center. Clinical, perioperative, and physician characteristics were collected. Multivariable logistic regression models were used to identify predictors of 30-day readmission, stratified by malignant and benign indications for hysterectomy., Results: Among 1649 women who underwent a hysterectomy (1009 for benign indications and 640 for malignancy), 6% were subsequently readmitted within 30 days (8.9% for malignancy vs 4.2% for benign; P < .0001). The mean time to readmission was 13 days (15 days for malignancy vs 10 days for benign; P = .004). The most common reasons for readmission were gastrointestinal (38%) and infectious (34%) etiologies, and 11.6% of readmitted patients experienced a perioperative complication. Among women undergoing hysterectomy for benign indications, a history of a laparotomy, including cesarean delivery (adjusted odds ratio [AOR], 2.12; 95% confidence interval [CI], 1.06-4.25; P = .03), as well as a perioperative complication (AOR, 2.41; 95% CI, 1.00-6.04; P = .05) were both associated with a >2-fold increased odds of readmission. Among women undergoing hysterectomy for malignancy, an American Society of Anesthesiologists Physical Status Classification of III or IV (AOR, 1.92; 95% CI, 1.05-3.50; P = .03), a longer length of initial hospitalization (3 days AOR, 7.83; 95% CI, 1.33-45.99; P = .02), and an estimated blood loss >500 mL (AOR, 3.29; 95% CI, 1.28-8.45; P = .01) were associated with a higher odds of readmission; however, women who underwent a laparoscopic hysterectomy (AOR, 0.32; 95% CI, 0.12-0.86; P = .02) and who were discharged on postoperative day 1 (AOR, 0.16; 95% CI, 0.03-0.82; P = .02) were at a decreased risk of readmission. Physician and operative characteristics were not significant predictors of readmission., Conclusion: This study found that malignancy, perioperative complications, and prior open abdominal surgery, including cesarean delivery, are significant risk factors for consequent 30-day readmission following index hysterectomy. It may be possible to identify patients at highest risk for readmission at the time of hysterectomy, which can assist in developing interventions to reduce such events., (Copyright © 2016 Elsevier Inc.

Background: Routine prenatal care includes physical examinations and weight measurement. Little is known about whether access barriers to medical diagnostic equipment, such as examination tables and weight scales, affect prenatal care among pregnant women with physical disabilities., Methods: We conducted 2-hour, in-depth telephone interviews with 22 women using a semistructured, open-ended interview protocol. All women had significant mobility difficulties before pregnancy and had delivered babies within the prior 10 years. We recruited most participants through social networks. We sorted interview transcript texts using used NVivo software and conducted conventional content analyses to identify major themes., Results: Interviewee's mean (standard deviation) age was 34.8 (5.3) years. Most were white, well-educated, and higher income; 8 women had spinal cord injuries, 4 cerebral palsy, and 10 had other conditions; 18 used wheeled mobility aids. Some women's obstetricians had height adjustable examination tables, which facilitated transfers for physical examinations. Other women had difficulty transferring onto fixed height examination tables and were examined while sitting in their wheelchairs. Family members and/or clinical staff sometimes assisted with transfers; some women reported concerns about transfer safety. No women reported being routinely weighed on an accessible weight scale by their prenatal care clinicians. A few were never weighed during their pregnancies., Conclusions: Inaccessible examination tables and weight scales impede some pregnant women with physical disabilities from getting routine prenatal physical examinations and weight measurement. This represents substandard care. Adjustable height examination tables and wheelchair accessible weight scales could significantly improve care and comfort for pregnant women with physical disabilities.

To develop a brief self-report assessment of the type and magnitude of stressors during the postpartum period. A cross-sectional study of a convenience sample of 138 women at Massachusetts General Hospital in Boston, MA completed a measure of postpartum stressors at their 6-week postpartum visit. Item analyses were conducted; items were eliminated based on low relevance, low endorsement, and cross-loadings, resulting in a 9-item measure. Items were summed to create a total postpartum stressors score. To establish concurrent validity with perceived stress, the total postpartum stressors score was correlated with the 4-item Perceived Stress Scale (PSS-4). The stressors score was tested for bivariate associations with depression (Patient Health Questionnaire-2) and with social support (three items adapted from the MOS Social Support Scale). The 9-item measure, which was comprised of three factors (baby care, well-being, and work) demonstrated good reliability (Cronbach's α = .74) and concurrent validity with the PSS-4 (r = .53; p < .001) in the current sample. The stressors total score was negatively associated with social support (p < .001) and was positively associated with depression symptoms (p < .001). The early psychometric results on this measure are promising and associated with postpartum social support and depressive symptoms. With additional research to enhance external validity, this measure could be used and tested in an intervention study at the 6-week postpartum visit to identify women at risk for distress.

Background: During pregnancy, upper airway resistance is increased, predisposing vulnerable women to pregnancy-related OSA. Elevation of the upper body increases upper airway cross-sectional area (CSA) and improves severity of OSA in a subgroup of nonpregnant patients (positional-dependent sleep apnea). We tested the hypothesis that elevated position of the upper body improves OSA early after delivery., Methods: Following institutional review board approval, we conducted a randomized, crossover study on two postpartum units of Massachusetts General Hospital. Women during the first 48 h after delivery were included. Polysomnography was performed in nonelevated and 45° elevated upper body position. Upper airway CSA was measured by acoustic pharyngometry in nonelevated, 45° elevated, and sitting body position., Results: Fifty-five patients were enrolled, and measurements of airway CSA obtained. Thirty patients completed polysomnography in both body positions. Elevation of the upper body significantly reduced apnea-hypopnea index (AHI) from 7.7 ± 2.2/h in nonelevated to 4.5 ± 1.4/h in 45° elevated upper body position (P = .031) during sleep. Moderate to severe OSA (AHI > 15/h) was diagnosed in 20% of postpartum patients and successfully treated by elevated body position in one-half of them. Total sleep time and sleep architecture were not affected by upper body elevation. Change from nonelevated to sitting position increased inspiratory upper airway CSA from 1.35 ± 0.1 cm2 to 1.54 ± 0.1 cm2 during wakefulness. Position-dependent increase in CSA and decrease in AHI were correlated (r = 0.42, P = .022)., Conclusions: Among early postpartum women, 45° upper body elevation increased upper airway CSA and mitigated sleep apnea. Elevated body position might improve respiratory safety in women early after delivery., Trial Registry: ClinicalTrials.gov; No.: NCT01719224; URL: www.clinicaltrials.gov.

Objective: To assess whether maternal calcium channel blocker exposure during late pregnancy is independently associated with neonatal seizures after carefully controlling for confounding factors., Methods: Data were derived from the Medicaid Analytic eXtract for the years 2000-2007 and included 2,529,636 completed pregnancies. We compared the risk of neonatal seizures among neonates who were born to women who took calcium channel blockers in the final month of pregnancy to the risk in neonates born to women who did not use calcium channel blockers. Confounding was addressed through the use of propensity score matching., Results: A total of 22,908 (0.91%) pregnancies included exposure to calcium channel blockers during the final month of pregnancy. Neonatal seizures occurred in 53 (0.23%) neonates born to mothers exposed to calcium channel blockers and in 4,609 (0.18%) neonates of unexposed women (unadjusted odds ratio [OR] 1.26, 95% confidence interval [CI] 0.96-1.65). After accounting for confounders, there was no increase in risk of neonatal seizures associated with calcium channel blocker exposure (OR 0.95, 95% CI 0.70-1.30). This null finding was robust across multiple sensitivity analysis., Conclusion: In this large, carefully controlled, population-based cohort study, there was no significant increase in the risk of neonatal seizures in neonates attributable to maternal calcium channel blocker exposure in late pregnancy. The results suggest that calcium channel blockers can be used by obstetricians in late pregnancy without excess concern about this neonatal complication., Level of Evidence: II.

Background: Little is known about current societal attitudes toward women with significant mobility disability who are visibly pregnant., Objective: To use qualitative descriptive analysis methods to examine perceptions of women with significant mobility disability about how strangers reacted to their visible pregnancies., Methods: In late 2013, we conducted 2-h telephone interviews with 22 women with significant mobility difficulties who had delivered babies within the prior 10 years. The semi-structured, open-ended interview protocol addressed wide-ranging pregnancy-related topics, including statements from strangers. Most participants were recruited through social networks, coming from 17 states nationwide. We used NVivo to sort the texts for content analysis., Results: The women's mean (standard deviation) age was 34.8 (5.3) years; most were white, well-educated, and higher income, although half had Medicaid during their pregnancies; and 18 used wheeled mobility aids. Eighteen women described memorable interactions with strangers relating to their pregnancies or newborn babies. Strangers' statements fell into six categories: (1) curious; (2) intrusively and persistently curious; (3) hostile, including concerns that taxpayers would end up supporting the mother and child; (4) questioning woman's competence as a potential parent; (5) oblivious, not recognizing visible pregnancy or motherhood; and (6) positive. Many women reported strangers asking how their pregnancy had happened. The women doubted that visibly pregnant women without disabilities evoke the same reactions from strangers., Conclusions: Women with mobility disability who are visibly pregnant may perceive reactions from strangers that appear intrusive. Planning ahead for handling such encounters could reduce the stresses of these interactions., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Objective: To evaluate whether an electronic health record (EHR) reminder improves rates of screening for type 2 diabetes in women with prior gestational diabetes., Methods: We randomly allocated primary care providers (by clinic site) to a reminder for type 2 diabetes screening within the EHR or to usual care. Women with previous gestational diabetes mellitus were identified through an automated search of laboratory results and the problem list. We compared rates of screening during the study period (2010-2012) in women at intervention sites with those at control sites. With a sample size of 850 participants, we had 80% power to detect a 15% difference in screening rates., Results: We included 847 individuals seen at a participating clinic during the study period, of whom 471 were at a reminder clinic and 376 were at a control clinic. A similar proportion of women were screened for type 2 diabetes in both groups (n=265, 56.3% of the reminder group compared with n=206, 54.8% of the control group, P=.67; adjusted odds ratio [OR] 1.04, 95% confidence interval [CI] 0.79-1.38). Patient characteristics associated with risk for diabetes including body mass index (adjusted OR per kg/m 1.05, 95% CI 1.01-1.08) and race (adjusted OR for nonwhite race 2.14, 95% CI 1.57-2.92) were significantly associated with screening., Conclusion: A simple EHR reminder did not increase the rate of diabetes screening in women with prior gestational diabetes mellitus., Clinical Trial Registration: ClinicalTrials.gov, www.clinicaltrials.gov, NCT01288144., Level of Evidence: I.

Growing numbers of reproductive-age US women with chronic physical disabilities (CPD) raise questions about their pregnancy experiences. Little is known about the health risks of women with versus without CPD by current pregnancy status. We analyzed cross-sectional, nationally-representative National Health Interview Survey data from 2006 to 2011, which includes 47,629 civilian, noninstitutionalized women ages 18-49. NHIS asks about specified movement difficulties, current pregnancy, and various health and health risk indicators, including tobacco use and body mass index (BMI). We used responses from eight movement difficulty and other questions to identify women with mobility difficulties caused by chronic physical health conditions. Across all women regardless of CPD, women reporting current pregnancy are significantly less likely to currently smoke tobacco and report certain mental health problems. Among currently pregnant women only, women with CPD are more likely to smoke cigarettes every day (12.2 %) versus 6.3 % for pregnant women without CPD (p ≤ 0.001). Among currently pregnant women, 17.7 % of women with CPD have BMIs in the non-overweight range, compared with 40.1 % of women without CPD (p ≤ 0.0001). Currently pregnant women with CPD are significantly more likely to report having any mental health problems, 66.6 % compared with 29.7 % among women without CPD (p ≤ 0.0001). For all women, currently pregnant women appear to have fewer health risks and mental health concerns than nonpregnant women. Among pregnant women, women with CPD have higher rates than other women of health risk factors that could affect maternal and infant outcomes.

Objective: To examine the teratogenic potential of statins., Design: Cohort study., Setting: United States., Participants: A cohort of 886,996 completed pregnancies linked to liveborn infants of women enrolled in Medicaid from 2000 to 2007., Methods: We examined the risk of major congenital malformations and organ specific malformations in offspring associated with maternal use of a statin in the first trimester. Propensity score based methods were used to control for potential confounders, including maternal demographic characteristics, obstetric and medical conditions, and use of other drugs., Results: 1152 (0.13%) women used a statin during the first trimester. In unadjusted analyses, the prevalence of malformations in the offspring of these women was 6.34% compared with 3.55% in those of women who did not use a statin in the first trimester (relative risk 1.79, 95% confidence interval 1.43 to 2.23). Controlling for confounders, particularly pre-existing diabetes, accounted for this increase in risk (1.07, 0.85 to 1.37). There were also no statistically significant increases in any of the organ specific malformations assessed after accounting for confounders. Results were similar across a range of sensitivity analyses., Conclusions: Our analysis did not find a significant teratogenic effect from maternal use of statins in the first trimester. However, these findings need to be replicated in other large studies, and the long term effects of in utero exposure to statins needs to be assessed, before use of statins in pregnancy can be considered safe., (© Bateman et al 2015.)

Objective: Chronic hypertension is a common medical condition in pregnancy. The purpose of the study was to examine the association between maternal chronic hypertension and the risk of congenital malformations in the offspring., Study Design: We defined a cohort of 878,126 completed pregnancies linked to infant medical records using the Medicaid Analytic Extract. The risk of congenital malformations was compared between normotensive controls and those with treated and untreated chronic hypertension. Confounding was addressed using propensity score matching., Results: After matching, compared with normotensive controls, pregnancies complicated by treated chronic hypertension were at increased risk of congenital malformations (odds ratio [OR], 1.3; 95% confidence interval [CI], 1.2-1.5), as were pregnancies with untreated chronic hypertension (OR 1.2; 95% CI, 1.1-1.3). In our analysis of organ-specific malformations, both treated and untreated chronic hypertension was associated with a significant increase in the risk of cardiac malformations (OR, 1.6; 95% CI, 1.4-1.9 and OR, 1.5; 95% CI, 1.3-1.7, respectively). These associations persisted across a range of sensitivity analyses., Conclusion: There is a similar increase in the risk of congenital malformations (particularly cardiac malformations) associated with treated and untreated chronic hypertension that is independent of measured confounders. Studies evaluating the teratogenic potential of antihypertensive medications must control for confounding by indication. Fetuses and neonates of mothers with chronic hypertension should be carefully evaluated for potential malformations, particularly cardiac defects., (Copyright © 2015 Elsevier Inc.

Objective: Little is known about how functional impairments might affect the pregnancies of women with mobility disability. We aimed to explore complications that arise during pregnancy that are specifically related to physical functional impairments of women with significant mobility disabilities., Design: Qualitative descriptive analysis., Setting: Telephone interviews with women from 17 USA states., Sample: 22 women with significant mobility difficulties who had delivered babies within the prior 10 years; most participants were recruited through social networks., Methods: We conducted 2-h, in-depth telephone interviews using a semi-structured, open-ended interview protocol. We used NVIVO software to sort interview transcript texts for conventional content analyses., Main Outcome Measures: Functional impairment-related complications during pregnancy., Results: The women's mean (standard deviation) age was 34.8 (5.3) years. Most were white, well-educated, and higher income; eight women had spinal cord injuries, four cerebral palsy, and 10 had other conditions; 18 used wheeled mobility aids; and 14 had cesarean deliveries (eight elective). Impairment-related complications during pregnancy included: falls; urinary tract and bladder problems; wheelchair fit and stability problems that reduced mobility and compromised safety; significant shortness of breath, sometimes requiring respiratory support; increased spasticity; bowel management difficulties; and skin integrity problems (this was rare, but many women greatly increased skin monitoring during pregnancy to prevent pressure ulcers)., Conclusions: In addition to other pregnancy-associated health risks, women with mobility disabilities appear to experience problems relating to their functional impairments. Pre-conception planning and in-depth discussions during early pregnancy could potentially assist women with mobility disabilities to anticipate and address these difficulties., (© 2014 Nordic Federation of Societies of Obstetrics and Gynecology.)
