Biological Testing and Interpretation of Laboratory Results Associated with Detecting Newborns with Substance Exposure.

BACKGROUND: Substance use during pregnancy is common, as is biological testing that is intended to help identify prenatal exposures. However, there is no standardized requirement for biological testing with either maternal or newborn specimens, nor is there standardization related to when testing occurs, how frequently testing occurs, what specimen(s) to test, what substances to test for, or how to perform testing. CONTENT: We review common specimen types tested to detect maternal and newborn substance exposure with a focus on urine, meconium, and umbilical cord tissue. We also review common analytical methods used to perform testing, including immunoassay, and mass spectrometry platforms. Considerations regarding the utilization of testing relative to the purpose of testing, the drug analyte(s) of interest, the specific testing employed, and the interpretation of results are emphasized to help guide decisions about clinical utilization of testing. We also highlight specific examples of unexpected results that can be used to guide interpretation and appropriate next steps. SUMMARY: There are strengths and limitations associated with all approaches to detecting substance exposure in pregnant persons as well as biological testing to evaluate a newborn with possible substance exposure. Standardization is needed to better inform decisions surrounding evaluation of substance exposures in pregnant people and newborns. If biological sampling is pursued, testing options and results must be reviewed in clinical context, acknowledging that false-positive and -negative results can and do occur.

Maternal psychophysiology profiles: associations with prenatal opioid use, maternal emotion dysregulation, and newborn neurobehavior.

BACKGROUND: Opioid use among pregnant women has more than quadrupled over the past 20 years; however, comorbid risk factors such as emotion dysregulation confound the developmental consequences of prenatal opioid use. Maternal respiratory sinus arrhythmia (RSA) may help to disentangle the comorbid risk factors of prenatal emotion dysregulation and substance use and isolate their consequences on newborn neurobehavior. METHODS: We examined maternal RSA in response to a mild, infant-related stress task in pregnant people (N = 192; 30 on medications for opioid use disorder) recruited from hospitals and a specialty prenatal clinic for substance use disorder. RESULTS: Three latent profiles emerged based on maternal RSA reactivity. Mothers with RSA increasing (Profile 3; more nervous system dysregulation) had higher levels of emotion dysregulation than mothers with RSA decreasing (Profile 1; well-regulated nervous system responses) but were not more likely to use opioids. Additionally, RSA profiles were associated with newborn neurobehavior, including attention, regulation, handling, and arousal. CONCLUSIONS: Given the variability in opioid use across RSA profiles and profile associations with newborn neurodevelopment, future studies should examine protective factors in pregnant individuals using opioids who show more flexible RSA responses. IMPACT: Our study examined maternal psychophysiology and newborn outcomes in a unique population with high levels of emotion dysregulation and opioid use. Three profiles of maternal respiratory sinus arrythmia (RSA) reactivity were identified during pregnancy: decreasing, blunted, and increasing. The RSA increasing and blunted profiles were associated with higher emotion dysregulation than the decreasing profile. Most pregnant people on medications for opioid use disorder (65%) were grouped into the blunted profile, suggesting they might be more at risk for dysregulated RSA reactivity. Differences in RSA profiles were associated with newborn outcomes, with increasing and blunted RSA predicting more newborn neurobehavioral dysregulation.

Semiparametric sensitivity analysis: unmeasured confounding in observational studies.

Establishing cause-effect relationships from observational data often relies on untestable assumptions. It is crucial to know whether, and to what extent, the conclusions drawn from non-experimental studies are robust to potential unmeasured confounding. In this paper, we focus on the average causal effect (ACE) as our target of inference. We generalize the sensitivity analysis approach developed by Robins et al., Franks et al., and Zhou and Yao. We use semiparametric theory to derive the non-parametric efficient influence function of the ACE, for fixed sensitivity parameters. We use this influence function to construct a one-step, split sample, truncated estimator of the ACE. Our estimator depends on semiparametric models for the distribution of the observed data; importantly, these models do not impose any restrictions on the values of sensitivity analysis parameters. We establish sufficient conditions ensuring that our estimator has $\sqrt{n}$ asymptotics. We use our methodology to evaluate the causal effect of smoking during pregnancy on birth weight. We also evaluate the performance of estimation procedure in a simulation study.

Consensus pregnancy-related criteria for suicide and unintentional overdoses using a Delphi process.

Suicide and unintentional overdose are leading manners of preventable death during and within a year of pregnancy. Recently, the Utah Maternal Mortality Review Committee (MMRC) developed 10 criteria to guide pregnancy-related classification of these deaths. Our objective was to (1) evaluate if consensus could be reached across experts in maternal mortality review when applying criteria to the determination of pregnancy-relatedness in mock MMRC case evaluation and (2) assess how additional case information shifted participants' determination of pregnancy-relatedness in these mock cases. We used a modified Delphi process to evaluate criteria for pregnancy-related suicides and unintentional overdose. The study team developed base case scenarios to reflect the 10 proposed criteria. Base scenarios varied in timing of death (prenatal or delivery, early postpartum (<6 months), late postpartum (6-12 months)) and level of additional information available (e.g., informant interviews, social media posts). Consensus in favor of a criterion was met when ≥75% of participants identified a case as pregnancy-related in at least 1 scenario. Fifty-eight participants, representing 48 MMRCs, reviewed scenarios. Of 10 proposed criteria, 8 reached consensus. Overall, participants classified 19.4% of base case scenarios as pregnancy-related, which increased to 56.8% with additional information. Pregnancy-related classification changed across timing of death and with availability of additional information (prenatal or delivery 27.7% versus 84.6%; early postpartum 30.0% versus 58.3%; late postpartum 0.0% versus 25.0%, respectively). We identified consensus supporting the application of 8 standardized criteria in MMRC determinations of pregnancy-relatedness among suicide and unintentional overdose deaths.

Indicated Opioids in Pregnancy: Guidance on Providing Comprehensive Care.

In modern obstetric practice, providers will encounter patients for whom opioid use in pregnancy is reasonable or even necessary. A "one-size-fits-all" approach to the counseling and management of such patients is misguided. Understanding indications for ongoing opioid use in pregnancy is essential to patient-centered care. Specifically, recognition of the nuanced differences between opioid dependence and opioid use disorder is crucial for appropriate diagnosis, screening for common concurrent conditions, adequately counseling about individualized maternal and perinatal risks, and accurate documentation of diagnoses and medical decision-making. In this paper, we explore the current typical scenarios in which opioid use in pregnancy may be encountered, ongoing opioid prescribing should be considered, and provide a guide for the obstetric provider to navigate the antepartum, intrapartum, and postpartum periods. KEY POINTS: · Opioid use in pregnant and postpartum individuals is not rare.. · Obstetric providers may elect to assume opioid prescribing.. · Obstetric providers are positioned to optimize outcomes for the mother-infant dyad..

Interpregnancy Body Mass Index Change and Offspring Mortality Risk following the Second Pregnancy.

OBJECTIVE: The aim of the study is to examine the impact of maternal interpregnancy body mass index (BMI) change on subsequent offspring mortality risk. STUDY DESIGN: This is a retrospective cohort study of women who had two consecutive live singleton deliveries of at least 20 weeks' gestation from the Utah Population Database. Our exposure was defined as interpregnancy BMI change from the date of first delivery to the conception date of subsequent pregnancy. We categorized BMI change as: < - 1, -1 to 0, 0 to <1 (reference), 1 to 2, 2 to 4, ≥4 kg/m2. Our primary outcome was all-cause age-specific mortality during four time periods: neonatal (≤28 days), infant (29 days to <1 year old), childhood ((≥1 to <5 years old), and late childhood (5 to <18 years old). We also examined mortality specifically attributed to congenital anomalies. Analyses used Cox proportional hazard models stratified by full term (≥37 weeks) and preterm (<37 weeks) deliveries. All models were adjusted for relevant confounders. RESULTS: Of 266,752 women, among full-term deliveries, women with a BMI increase of 4 kg/m2 or more had an increased risk of neonatal mortality in their subsequent pregnancy (hazard ratio or HR = 1.72, 95% confidence interval or CI: 1.23-2.41) Women who lost 1 kg/m2 or more between deliveries also had increased neonatal mortality (HR = 1.46, 95% CI: 1.04-2.05). There were no differences in infant, early, or late childhood mortality by interpregnancy BMI change. Maternal interpregnancy interval weight loss of 1 kg/m2 or more and weight gain of ≥4 kg/m2 also had increased risk of mortality associated with congenital anomalies or conditions arising during the neonatal period following their subsequent delivery. CONCLUSION: Women with significant interpregnancy weight gain and modest weight loss have a significant increased risk of neonatal mortality following their subsequent pregnancy. KEY POINTS: · Significant weight gain between deliveries increases the risk of neonatal death.. · Modest weight loss between deliveries increases the risk of neonatal death.. · This risk may be partially explained by increased risk of congenital malformations..

Experiences with use of technology and telehealth among women with perinatal depression.

BACKGROUND: Perinatal depression (PD) affects 10-20% of childbearing women. Telehealth is increasingly utilized for mental health services to increase access to care and overcome COVID-19 pandemic barriers. Women's perspectives on telehealth services for PD is unknown, however. This study's primary objective was to obtain the perspectives of women who participated in an 8-week group videoconference intervention for PD symptoms, including how technology impacted their experience. METHODS: We utilized theoretical sampling and included perinatal women who had completed the 8-week mindfulness-based cognitive-behavioral intervention group. Semi-structured focus groups with four to six women were conducted on a videoconference platform. Primary analysis used grounded theory and a secondary analysis used qualitative description and was conducted by two coding teams. The teams collaborated on the final themes across the analyses. RESULTS: Three groups, with a total of 17 participants were conducted. Composition consisted of seven postpartum and ten pregnant women from the 47 total participants. Identified core themes regarding their experiences of the videoconference intervention were: positive experiences, negative experiences, suggestions and ideas, and screening and communication. CONCLUSION: This study provides growing evidence informed by perinatal women of positive experiences with engagement in a videoconference intervention for PD. Telehealth may be a reasonable and acceptable platform to increase access and retention for mental health services in childbearing women. Further, this pilot work showcases videoconferencing delivery for a wide range of effective and affordable mental health services in low-resource communities.

Directly Measured Costs of Severe Maternal Morbidity Events during Delivery Admission Compared with Uncomplicated Deliveries.

OBJECTIVE: To estimate the actual excess costs of care for delivery admissions complicated by severe maternal morbidity (SMM) compared with uncomplicated deliveries. STUDY DESIGN: This is a retrospective cohort study of all deliveries between October 2015 and September 2018 at a single tertiary academic center. Pregnant individuals ≥ 20 weeks' gestation who delivered during a hospital admission (i.e., a "delivery admission") were included. The primary exposure was SMM, as defined by Centers for Disease Control and Prevention (CDC) criteria, CDC criteria excluding blood transfusion, or by validated hospital-defined criteria (intensive care unit admission or ≥ 4 units of blood products). Potential SMM events identified via administrative and blood bank data were reviewed to confirm SMM events had occurred. Primary outcome was total actual costs of delivery admission derived from time-based accounting and acquisition costs in the institutional Value Driven Outcomes database. Cost of delivery admissions with SMM events was compared with the cost of uncomplicated delivery using adjusted generalized linear models, with separate models for each of the SMM definitions. Relative cost differences are reported due to data restrictions. RESULTS: Of 12,367 eligible individuals, 12,361 had complete cost data. Two hundred and eighty individuals (2.3%) had confirmed SMM events meeting CDC criteria. CDC criteria excluding transfusion alone occurred in 1.0% (n = 121) and hospital-defined SMM in 0.6% (n = 76). In adjusted models, SMM events by CDC criteria were associated with a relative cost increase of 2.45 times (95% confidence interval [CI]: 2.29-2.61) the cost of an uncomplicated delivery. SMM by CDC criteria excluding transfusion alone was associated with a relative increase of 3.26 (95% CI: 2.95-3.60) and hospital-defined SMM with a 4.19-fold (95% CI: 3.64-4.83) increase. Each additional CDC subcategory of SMM diagnoses conferred a relative cost increase of 1.60 (95% CI: 1.43-1.79). CONCLUSION: SMM is associated with between 2.5- and 4-fold higher cost than uncomplicated deliveries. KEY POINTS: · Severe maternal morbidity as defined by CDC criteria confers a 2.5-fold increase in delivery hospitalization costs.. · Intensive care unit admission or ≥ 4 units of blood products confer a fourfold increase in cost.. · Costs of maternal morbidity may motivate SMM review..

Maternal Marijuana Exposure, Feto-Placental Weight Ratio, and Placental Histology.

OBJECTIVE: Marijuana use is associated with placenta-mediated adverse pregnancy outcomes including fetal growth restriction, but the mechanism remains uncertain. The objective was to evaluate the association between maternal marijuana use and the feto-placental weight ratio (FPR). Secondarily, we aimed to compare placental histology of women who used marijuana to those who did not. STUDY DESIGN: This was a secondary analysis of singleton pregnancies enrolled in a multicenter and case-control stillbirth study. Prior marijuana use was detected by electronic medical record abstraction or cord homogenate positive for 11-nor-delta-9-tetrahydrocannabinol-9-carboxylic acid. Prior tobacco use was detected by self-report or presence of maternal serum cotinine. Stillbirths and live births were considered separately. The primary outcome was FPR. Association of marijuana use with FPR was estimated with multivariable linear modeling adjusted for fetal sex, preterm birth, and tobacco use. Comparisons between groups for placental histology were made using Chi-square and stratified by live birth and stillbirth, term and preterm deliveries, and fetal sex. RESULTS: Of 1,027 participants, 224 were stillbirths and 803 were live births. Overall, 41 (4%) women used marijuana during the pregnancy. The FPR ratio was lower among exposed offspring but reached statistical significance only for term stillbirths (mean 6.84 with marijuana use vs. mean 7.8 without use, p < 0.001). In multivariable modeling, marijuana use was not significantly associated with FPR (p = 0.09). There were no differences in histologic placental features among those with and without marijuana use overall or in stratified analyses. CONCLUSION: Exposure to marijuana may not be associated with FPR. Similarly, there were no placental histologic features associated with marijuana exposure. Further study of the influence of maternal marijuana use on placental development and function is warranted to better understand the association between prenatal marijuana use and poor fetal growth. KEY POINTS: · Maternal marijuana exposure was not associated with the feto-placental weight ratio.. · Marijuana exposure was not associated with differences in placental histology.. · Concerning trend toward lower feto-placental weight ratios among marijuana-exposed stillbirths..

Attitudes, self-efficacy, and practices related to opioid risk assessment and mitigation: A comparison of health care professionals in rural communities.

Background: Health care professionals (HCPs) play an important role in opioid misuse and opioid use disorder (OUD) screening/identification, mitigation, and referral to treatment. This study compared attitudes, self-efficacy, and practices related to opioid risk assessment and mitigation among pregnancy and non-pregnancy HCPs in rural communities. Methods: We conducted a secondary analysis of cross-sectional, self-report survey data of HCPs in two rural counties in southern Utah. Pregnancy HCPs were identified by a question asking whether they provide care to pregnant patients. HCPs' attitudes toward their patients with opioid misuse/OUD were measured using the Survey of Attitudes and Perceptions questionnaire. Self-efficacy and practices related to opioid risk assessment and mitigation were captured with questions asking about assessment and screening of opioid use, advisement to change opioid use behavior, and referral to treatment for OUD. We used linear regression analyses to estimate associations between HCPs' attitudes toward patients with opioid misuse/OUD and their self-efficacy and use of opioid risk assessment and mitigation practices. Results: This sample included a total of 132 HCPs, including 82 pregnancy HCPs and 50 non-pregnancy HCPs. Attitudes domains were similar among pregnancy and non-pregnancy HCPs. Among pregnancy HCPs, role adequacy (ß = .48, 95% CI = .16-.80), role legitimacy (ß = .72, 95% CI = .21-1.22), motivation (ß = .68, 95% CI = .14-1.21), and positive task-specific self-esteem (ß = 1.52, 95% CI = .70-2.35) were positively associated with more frequent use of opioid risk assessment and mitigation practices, while attitudes were not associated with these practices among non-pregnancy HCPs. Conclusions: Training initiatives that lead to improved HCP attitudes could improve opioid care management among rural pregnancy HCPs. More research is needed to determine approaches to increase the use of opioid risk assessment and mitigation practices among rural non-pregnancy HCPs.

Trends in Opioid and Psychotropic Prescription in Pregnancy in the United States From 2001 to 2015 in a Privately Insured Population : A Cross-sectional Study.

BACKGROUND: Opioid and psychotropic prescriptions are common during pregnancy. Little is known about coprescriptions of both medications in this setting. OBJECTIVE: To describe opioid prescription among women who are prescribed psychotropics compared with women who are not. DESIGN: Cross-sectional study. SETTING: U.S. commercial insurance beneficiaries from MarketScan (2001 to 2015). PARTICIPANTS: Pregnant women at 22 weeks' gestation or greater who were insured continuously for 3 months or more before pregnancy through delivery. MEASUREMENTS: Opioid prescription, dosage thresholds (morphine milligram equivalents [MME] of ≥50/day and ≥90/day), number of opioid agents (≥2), and duration (≥30 days) among those with and without prescription of psychotropics, from 2011 to 2015. RESULTS: Among 958 980 pregnant women, 10% received opioids only, 6% psychotropics only, and 2% opioids with coprescription of psychotropics. Opioid prescription was higher among women prescribed psychotropics versus those who were not (26.5% vs. 10.7%). From 2001 to 2015, psychotropic prescription overall increased from 4.4% to 7.6%, opioid prescription without coprescription of psychotropics decreased from 11.9% to 8.4%, and opioids with coprescription decreased from 28.1% to 22.0%. Morphine milligram equivalents of 50 or greater per day decreased for women with and without coprescription (29.6% to 17.3% and 22.8% to 18.5%, respectively); MME of 90 or greater per day also decreased in both groups (15.0% to 4.7% and 11.5% to 4.2%, respectively). Women prescribed opioids only were more likely to have an antepartum hospitalization compared with those with neither prescription, as were women with coprescription versus those prescribed psychotropics only. Compared with those prescribed opioids only, women with coprescriptions were more likely to exceed MME of 90 or greater per day and to be prescribed 2 or more opioid agents and for 30 days or longer. Number and duration of opioids increased with benzodiazepine and gabapentin coprescription. LIMITATION: Inability to determine appropriateness of prescribing or overdose events. CONCLUSION: Opioids are frequently coprescribed with psychotropic medication during pregnancy and are associated with antepartum hospitalization. A substantial proportion of pregnant women are prescribed opioids at doses that increase overdose risk and exceed daily recommendations. PRIMARY FUNDING SOURCE: None.

Experiences of Nursing Professionals Working With Women Diagnosed With Opioid Use Disorder and Their Newborns: Burnout and the Need for Support.

BACKGROUND: As the rate of opioid use in pregnancy escalates, there are a growing number of women diagnosed with opioid use disorder (OUD) and their newborns being cared for in inpatient settings. PURPOSE: In this study, we sought to better understand the experiences of nurses and nursing assistants working with women diagnosed with OUD and their newborns. By identifying the needs of nurses and nursing assistants, the findings from this study may contribute to reductions in stigma and improved patient care. METHODS: Nurses and nursing assistants were recruited from a postpartum unit at a large urban hospital in Utah. Participants (n = 30) attended up to 4 semistructured focus groups. We utilized Braun and Clarke's 6-phase approach to thematic analysis to analyze transcribed interviews. FINDINGS/RESULTS: Themes identified during the data analysis process included negative feelings and reactions toward patients; preferential concern for the newborn over maternal well-being; and identification of organizational and training needs to overcome these challenges. IMPLICATIONS FOR PRACTICE: These findings identify strategies for addressing challenges faced by nurses and nursing assistants in caring for women diagnosed with OUD and their newborns. IMPLICATIONS FOR RESEARCH: Future research should examine the effectiveness of approaches to reduce behaviors influenced by stigma among nurses and nursing assistants working with women diagnosed with OUD and their newborns, as well as employee and patient satisfaction, and long-term health outcomes.

Intergenerational transmission of emotion dysregulation: Part I. Psychopathology, self-injury, and parasympathetic responsivity among pregnant women.

The World Health Organization recently reported that maternal mental health is a major public health concern. As many as one in four women suffer from psychiatric disorders at some point during pregnancy or the first postpartum year. Furthermore, self-injurious thoughts and behaviors (SITBs) represent one of the leading causes of death among women during this time. Thus, efforts to identify women at risk for serious forms of psychopathology and especially for SITBs are of utmost importance. Despite this urgency, current single-diagnostic approaches fail to recognize a significant subset of women who are vulnerable to perinatal stress and distress. The current study was among the first to investigate emotion dysregulation-a multilevel, transdiagnostic risk factor for psychopathology-and its associations with stress, distress, and SITBs in a sample of pregnant women (26-40 weeks gestation) recruited to reflect a range of emotion dysregulation. Both self-reported emotion dysregulation and respiratory sinus arrhythmia, a biomarker of emotion dysregulation, demonstrated expected associations with measures of mental health, including depression, anxiety, borderline personality pathology, and SITBs. In addition, self-reported emotion dysregulation was associated with blunted respiratory sinus arrhythmia responsivity to an ecologically valid infant cry task. Findings add to the literature considering transdiagnostic risk during pregnancy using a multiple-levels-of-analysis approach.

Stimulant Use in Pregnancy: An Under-recognized Epidemic Among Pregnant Women.

Stimulant use, including cocaine, methamphetamines, ecstasy, and prescription stimulants, in pregnancy is increasingly common. In the United States, stimulants are the second most widely used and abused substances during pregnancy and pregnant women using stimulants in pregnancy are at increased risk of adverse perinatal, neonatal, and childhood outcomes. In this review, we describe the pharmacology, pathophysiology, and epidemiology of stimulants, summarize the maternal and neonatal effects of perinatal stimulant use, and outline treatment options for stimulant use disorders among pregnant women. Development of effective treatment strategies for stimulant use disorders identified among pregnant women are urgently needed.

Factors Associated with Previable Delivery following Second Trimester Rupture of Membranes.

OBJECTIVE: To identify factors associated with previable delivery in second trimester preterm rupture of membranes (PROM). STUDY DESIGN: We conducted a single-center retrospective cohort study of women with pregnancies complicated by second trimester PROM (14.0-21.9 weeks' gestation) from 2000 to 2015 who elected expectant pregnancy management and achieved at least 24 hours latency. Maternal characteristics and clinical factors were compared among pregnancies that reached viability (≥ 23.0 weeks) and pregnancies delivered before viability (< 23.0 weeks) using appropriate statistical methods. RESULTS: Of 73 pregnancies complicated by second trimester PROM, 49 (67%) delivered before viability. Maternal race, history of preterm birth, and tobacco use were similar between women who delivered < 23 weeks versus ≥ 23 weeks. Gestational age at PROM, cervical dilation > 1cm, Group B streptococcus carrier status, bacterial vaginosis, and chlamydial infection during pregnancy were similar between groups. Median time to delivery was significantly shorter in women who delivered < 23 weeks compared with those who reached ≥ 23 weeks (6 vs. 46 days, p < 0.01). CONCLUSION: Previable delivery occurred in the majority of women with second trimester PROM. No maternal or clinical factors were associated with delivery prior to viability. Counseling women with second trimester PROM should include the inability to determine which pregnancies will reach viability.

The Effect of Blood Loss on Cefazolin Levels in Women Undergoing Cesarean Delivery.

OBJECTIVE: To quantify the effects of operative blood loss during cesarean on tissue and plasma cefazolin concentrations. STUDY DESIGN: This was a prospective observational study of singleton pregnancies undergoing scheduled cesarean between 34 and 40 weeks. Cefazolin administered prior to skin incision. Maternal plasma samples were obtained (Time 1[T1]: immediately, T2: 20 minutes, T3: 40 minutes, and T4: 60 minutes after cefazolin infusion). Subcutaneous adipose tissue sampled before and after fascia. Primary outcome was subcutaneous adipose cefazolin level after fascial closure. Formal quantitative blood loss (QBL) performed. Women with higher QBL, those at/above 75% of QBL in this population, were compared with those with lower QBL (QBL below 75%). Data analyzed using bivariable statistics. RESULTS: Ninety-two women were screened, 32 were eligible, and 20 enrolled. Median QBL was 630 mL (interquartile range [IQR]: 473-818) and 1,160 mL (IQR: 1,000-1,560) in the low and high QBL groups, respectively. Demographics and operative characteristics were similar. Median adipose cefazolin level after fascial closure did not differ between the groups (3.5 vs. 3.9 µg/g, p = 0.75). No differences in maternal plasma cefazolin concentrations between the groups at any time point or in pharmacokinetic parameters were seen. CONCLUSION: Intraoperative maternal plasma concentrations and adipose levels of cefazolin are similar between women with high and low blood loss at the time of cesarean delivery.

The Use of a Game-Based Decision Aid to Educate Pregnant Women about Prenatal Screening: A Randomized Controlled Study.

PURPOSE: This project developed and evaluated the efficacy of a game decision aid among pregnant women about prenatal screening in a randomized controlled study. STUDY DESIGN: Participants were recruited from an obstetric clinic of an academic urban medical center and randomized (n = 73) to one of two study groups: the control group (n = 39) that used a brochure or the intervention group (n = 34) that also used a game decision aid. RESULT: Participants who played the game had higher knowledge scores (m = 21.41, standard deviation [SD] = 1.74) than participants in the control group (m = 19.59; SD = 3.31), p = 0.004. The median time of game playing was 6:43 minutes (range: 2:17-16:44). The groups were similar in frequency of completing screening after the study, control = 6 (15%) versus intervention = 11 (32%), p = 0.087. However, the more interaction with the game resulted in more positive attitudes toward screening. CONCLUSION: The addition of a game decision aid was effective in educating pregnant women about prenatal screening. As other genetic testing decisions continue to increase within clinical care, game-based decision tools may be a constructive method of informed decision-making.

Perioperative Antibiotic Choice in Labored versus Unlabored Cesareans and Risk of Postcesarean Infectious Morbidity.

OBJECTIVE: This study aims to estimate postcesarean infectious morbidity in women receiving perioperative ß-lactam versus non-ß-lactam antibiotics. METHODS: We conducted a retrospective cohort analysis of the Maternal-Fetal Medicine Unit Cesarean Registry. The exposure was ß-lactam perioperative antibiotics versus non-ß-lactam regimens at cesarean delivery (CD). We stratified by labored versus unlabored CD. The primary composite outcome included wound infection, seroma, hematoma, endometritis, readmission due to wound complication, or debridement. Multivariable logistic regression estimated odds of wound complication by antibiotic regimen after adjusting for relevant confounders. RESULTS: Our analysis included 43,735 women who delivered via CD, 48% following labor. In both groups, 95% of women received ß-lactam antibiotics. In the labored CD group (n = 20,860), there was no significant difference in primary outcome by ß-lactam versus non-ß-lactam antibiotics (10.5 vs. 9.9%, p = 0.53). In the unlabored CD group (n = 22,875), women receiving non-ß-lactam antibiotics were more likely to experience a wound complication compared with those in the ß-lactam group (6.2 vs. 4.7%, p = 0.02, adjusted odds ratio: 1.39, 95% confidence interval: 1.08-1.80) after adjustment for clinical confounders. CONCLUSION: In unlabored CD, non-ß-lactam antibiotics have a higher risk of wound complications compared with ß-lactam regimens. Further study to optimize antibiotic prophylaxis for ß-lactam allergic women undergoing unlabored CD is warranted.

Maternal Gut Microbiome Biodiversity in Pregnancy.

OBJECTIVE: To measure maternal gut microbiome biodiversity in pregnancy. MATERIALS AND METHODS: In phase 1, maternal fecal samples were collected by rectal swab in 20 healthy pregnant women (14-28 weeks gestation) to measure bacterial abundance. In phase 2, fecal samples were collected from 31 women at enrollment (<20 weeks gestation, baseline) and at 36 to 39 weeks of gestation (follow-up). We assessed cluster analysis to assess bacterial community profiles at the phylum level longitudinally through pregnancy. DNA was extracted from swabs, followed by PCR of the bacterial 16s rRNA gene and multiplex high-throughput sequencing (Ion Torrent). RESULTS: In phase 1, 16 of 20 samples yielded usable data. White women (n = 10) had greater abundance of Firmicutes (23 ± 0.15 vs. 16% ± 0.75, p = 0.007) and Bacteroidetes (24 ± 0.14 vs. 19% ± 0.68, p = 0.015) compared with non-White women (n = 6). In the 11 paired specimens, Bacteroidetes increased in abundance from baseline to follow-up. Compared with women who gained weight below the median gestational weight gain (GWG, <15.4 kg), those who gained above the median GWG had increased abundance of Bacteroidetes (p = 0.02) and other phyla (p = 0.04). CONCLUSION: Maternal microbiome biodiversity changes as pregnancy progresses and correlates with GWG.

Reproductive rights advocacy: not just for the family-planning community.

Women and families benefit from access to the full spectrum of reproductive care, including family-planning services. We commend our family-planning colleagues on their tireless dedication to preserve the rights of women through advocacy. While several of our perinatology peers have also set an example by dedication to these issues, advocacy for patient access to reproductive care options has not been a focus of the larger perinatology community. The time has come for individual perinatologists, as well as the overall perinatology community, to join them and do the work needed to preserve access to safe care, including contraception and abortion services. In this call to action, we detail several ways that individuals and the community can become more involved in working for reproductive rights.
