RESUMO
BACKGROUND: Intrapartum glucose management is critical to reducing neonatal hypoglycemia shortly after birth. Although it is known that insulin is required for all pregnant individuals with type 1 diabetes mellitus, the optimal mode of intrapartum glycemic control is not known. OBJECTIVE: This study aimed to compare the effect of intrapartum use of continuous subcutaneous insulin infusion with that of intravenous insulin infusion for glucose management among pregnant individuals with type 1 diabetes mellitus on neonatal blood glucose levels. STUDY DESIGN: This was a randomized controlled trial of pregnant participants with type 1 diabetes mellitus. After written informed consent, participants were randomly allocated to 1 of 2 intrapartum insulin administration strategies: continuation of their continuous subcutaneous insulin infusion or intravenous insulin infusion. The primary outcome was the first neonatal blood glucose level. RESULTS: Between March 2021 and April 2023, 76 participants were approached, and 70 participants were randomized (35 participants in the intravenous insulin infusion group and 35 participants in the continuous subcutaneous insulin infusion group). The groups were similar in terms of age, race/ethnicity, pregravid body mass index, nulliparity, and gestational age at delivery. There was no statistically significant difference in the first neonatal glucose measurement between the 2 groups (50.1±23.4 vs 49.2±22.6; P=.86). In addition, there were no statistically significant differences in any secondary neonatal outcomes. Approximately 57.1% of neonates in the continuous subcutaneous insulin infusion group required either oral, intravenous, or both treatments for hypoglycemia, whereas 51.4% of neonates in the intravenous infusion group required treatment. In both groups, 28.6% of neonates required intravenous treatment for hypoglycemia. CONCLUSION: Pregnant individuals with type 1 diabetes mellitus using either intravenous insulin infusion or continuation of their continuous subcutaneous insulin infusion for intrapartum insulin administration had no difference in the primary outcome of neonatal hypoglycemia. Patients should be given the option of both glycemic management strategies intrapartum.

This study sought to compare test characteristics of hemoglobin A1c, oral glucose tolerance test and fasting plasma glucose for the development of gestational diabetes among women with prediabetes. Diabetes outcomes were compared by screening test used for prediabetes diagnosis among a retrospective cohort of pregnant patients between 2017-2021. During the study, 8132 patients received diabetes screening and 14.0% met criteria for prediabetes. By screening test, 75.1% were screened with hemoglobin A1c, 10.0% with fasting plasma glucose and 14.9% with a 75-g oral glucose tolerance test. Hemoglobin A1c had the highest positive predictive value (67.2%). Use of hemoglobin A1c was significantly more likely to identify women with GDM than oral glucose tolerance test (aOR 3.94, 95% CI 2.30-6.73). In this study cohort, hemoglobin A1c was able to identify patients that were more likely to develop GDM in an at-risk population.IMPACT STATEMENTWhat is already known on this subject? Prediabetes is becoming more common in the general population; however little is known about prediabetes in pregnancy. Women with prediabetes in pregnancy appear to be at increased risk of developing gestational diabetes mellitus, however there is minimal information about various screening tests performance in pregnancy for detection of prediabetes and subsequent gestational diabetes.What do the results of this study add? The results of this study compare three commonly used screening tests for screening for diabetes. When identifying women with prediabetes, they are at increased risk for developing gestational diabetes mellitus if identified by hemoglobin A1c.What are the implications of these findings for clinical practice and/or further research? The clinical implication of this study is that women can be screened with hemoglobin A1c in early pregnancy for both overt diabetes, but also may be identified as high risk with prediabetes. Among women with prediabetes by hemoglobin A1c, they remain at high risk for developing gestational diabetes mellitus.

The prevalence of diabetes in reproductive age women has been reported to be as high as 6.8%, with pregestational diabetes affecting 2% of all pregnancies. As cases of diabetes in children and adolescents rise, more patients will be entering reproductive age and pregnancy with diagnoses of obesity, prediabetes, type 2 diabetes. Early interventions of diet modification and exercise to maintain healthy weights can delay or even prevent these complications. It is critical for health care providers to emphasize the importance of preconception counseling in this high-risk patient population to reduce the morbidities associated with obesity and diabetes in pregnancy.

OBJECTIVE: To determine whether different modes of labor induction impact the success rate and perinatal morbidity in women undergoing trial of labor after cesarean (TOLAC). STUDY DESIGN: Retrospective review of the Consortium on Safe Labor electronic database from 2002�2008; women with a prior cesarean birth, desiring TOLAC, and requiring induction of labor were included. Oxytocin and Foley bulb induction methods were compared to amniotomy alone. Prostaglandin use was also reviewed but, given the small numbers, was not the focus of this study. RESULTS: Univariate analysis showed significantly greater incidence of hemorrhage >1,000 mL (p=0.0030) and transfusion (p=0.0076) with Foley bulb use. All methods of induction for TOLAC decreased repeat cesarean sections (OR 0.34, 95% CI 0.23�0.52, p<0.01). CONCLUSION: Induction of labor does not alter the success rate for TOLAC candidates, regardless of mode of induction. When choosing induction methods, one should be mindful of the apparent additional risk of increased blood loss and transfusion with intracervical Foley bulb usage.

OBJECTIVE: This study is designed to assess the effect of birth weight on the duration of labor. STUDY DESIGN: Retrospective review of the electronic database created by the Consortium on Safe Labor, reflecting labor and delivery information from 12 clinical centers from 2002 to 2008. Population included all laboring women in the 19 participating hospitals, excluding those with malpresentation, fetal anomalies, elective repeat cesarean, multiple gestations, gestational age less than 34 weeks, and delivery with less than two cervical examinations. Birth weight categories include less than 2,500 g, 2,500 to 3,000 g, 3,000 to 3,500 g, 3,500 to 4,000 g, and greater than 4,000 g. Interval censored regression analysis was used to determine distribution of times for cervical dilation progression in centimeters. RESULTS: A total of 146,904 maternal records were reviewed. In nulliparous, traverse times increased as birth weight increased, both in successful trial of labor and also those who ultimately required cesarean delivery (p < 0.01). In multiparous with successful trial of labor, traverse times increased as birth weight increased from 5 to 8 cm (p < 0.01). From 8 to 10 cm, traverse times increased by birth weight, though this was not statistically significant. CONCLUSION: We have shown that in a large cohort of contemporary laboring women, as birth weight increases, progression in labor is, in fact slower.

COVID-19 disproportionately affected minorities, while research barriers to engage underserved communities persist. Serological studies reveal infection and vaccination histories within these communities, however lack of consensus on downstream evaluation methods impede meta-analyses and dampen the broader public health impact. To reveal the impact of COVID-19 and vaccine uptake among diverse communities and to develop rigorous serological downstream evaluation methods, we engaged racial and ethnic minorities in Massachusetts in a cross-sectional study (April - July 2022), screened blood and saliva for SARS-CoV-2 and human endemic coronavirus (hCoV) antibodies by bead-based multiplex assay and point-of-care (POC) test and developed across-plate normalization and classification boundary methods for optimal qualitative serological assessments. Among 290 participants, 91.4 % reported receiving at least one dose of a COVID-19 vaccine, while 41.7 % reported past SARS-CoV-2 infections, which was confirmed by POC- and multiplex-based saliva and blood IgG seroprevalences. We found significant differences in antigen-specific IgA and IgG antibody outcomes and indication of cross-reactivity with hCoV OC43. Finally, 26.5 % of participants reported lingering COVID-19 symptoms, mostly middle-aged Latinas. Hence, prolonged COVID-19 symptoms were common among our underserved population and require public health attention, despite high COVID-19 vaccine uptake. Saliva served as a less-invasive sample-type for IgG-based serosurveys and hCoV cross-reactivity needed to be evaluated for reliable SARS-CoV-2 serosurvey results. Using the developed rigorous downstream qualitative serological assessment methods will help standardize serosurvey outcomes and meta-analyses for future serosurveys beyond SARS-CoV-2.

OBJECTIVE: To compare labor progression in twin vs singleton gestations. STUDY DESIGN: Retrospective review of electronic database created by Consortium on Safe Labor, reflecting labor and delivery information from 12 clinical centers 2002-2008. Women with twin gestations, cephalic presentation of presenting twin, gestational age ≥34 weeks, with ≥2 cervical examinations were included. Exclusion criteria were fetal anomalies or demise. Singleton controls were selected by the same criteria. Categorical variables were analyzed by χ(2); continuous by Student t test. Interval censored regression was used to determine distribution for time of cervical dilation in centimeters, or "traverse times," and controlled for confounding factors. Repeated-measures analysis constructed mean labor curves by parity and number of fetuses. RESULTS: A total of 891 twin gestations were compared with 100,513 singleton controls. Twin gestations were more often older, white or African American, earlier gestational age, increased prepregnancy body mass index, and with lower birthweight. There was no difference in number of prior cesarean deliveries, induction, or augmentation, or epidural use. Median traverse times increased at every centimeter interval in nulliparous twins, in both unadjusted and adjusted analysis (P < .01). A similar pattern was noted for multiparas in both analyses. Labor curves demonstrated a delayed inflection point in the labor pattern for nulliparous and multiparous twin gestations. CONCLUSION: Both nulliparous and multiparous women have slower progression of active phase labor with twins even when controlling for confounding factors.

OBJECTIVE: COVID-19 disease severely impacted pregnant persons, resulting in a significant increase in poor maternal health outcomes, with a disproportionate impact on minority populations and individuals with low socioeconomic status. We sought to determine demographic differences between birthing parents with SARS-CoV-2 infections who consented to research study participation versus those who declined. By analyzing demographic differences, we are able to ensure the generalizability of study outcomes and to aid in future prospective research design, with the ultimate goal of recognizing and ameliorating research disparities. METHODS: We conducted a secondary analysis to investigate demographic differences in patients who consented to versus declined study participation, in an effort to confirm the external validity of the study results and ensure minority populations most affected by SARS-CoV-2 infection were accurately represented. An IRB waiver was obtained to conduct retrospective chart review for demographic data collection of all patients approached for the COVID-19 Analysis on Perinatal Specimens Related to ExpoSure (CARES) research study. Pregnant patients with SARS-CoV-2 infection were identified at a single hospital center and approached either in person or via phone, with a translator if primary language listed as non-English. Demographic variables including race, ethnicity, primary language, and insurance type were obtained from the electronic medical record and analyzed via Chi-square to determine significant differences between individuals who consented to participation and those who declined participation. RESULTS: One hundred and fifty-eight pregnant patients with SARS-CoV-2 infection were approached for CARES study participation. Eighty-nine patients consented to study participation, while 69 declined study participation. A retrospective chart review was conducted on all 158 patients. Patients who identified as Black race or non-White race were more likely to decline participation (23.2%, p = .031, 68.1%, p = .026), compared to patients who identified as White (31.9%) (Table 1). Patients with public insurance were also more likely to decline study participation (72.5%, p = .049) compared to those with private insurance (27.5%). There was no significant difference between primary language spoken or ethnicity in patients who participated or declined. There was no difference in study participation between patients who identified as Asian race or Other race, compared to patients who identified as White race. CONCLUSIONS: We found significant differences in race and insurance type between pregnant patients with SARS-CoV-2 infection who consented versus declined research study participation. Our study showed that patients who identify as Black race or have public insurance are less likely to consent to research study participation. However, when demographics of consented patients are compared to county, state, and national demographics of female patients age 18-49 with confirmed SARS-CoV-2 infection obtained from a dataset collected by the Center for Disease Control and Prevention (CDC), there was no significant difference between race representation of patients who consented to study participation. This suggests that though the external validity of the CARES study is confirmed, more efforts need to be made to address racial and socioeconomic disparities in research participation.

Objective: The aim of this study was to characterize current diabetes screening practices in the first trimester of pregnancy in the United States, evaluate patient characteristics and risk factors associated with early diabetes screening, and compare perinatal outcomes by early diabetes screening. Methods: This was a retrospective cohort study of US medical claims data of persons diagnosed with a viable intrauterine pregnancy and who presented for care with private insurance before 14 weeks of gestation, without pre-existing pregestational diabetes, from the IBM MarketScan® database for the period January 1, 2016, to December 31, 2018. Univariate and multivariate analyses were used to evaluate perinatal outcomes. Results: A total of 400,588 pregnancies were identified as eligible for inclusion, with 18.0% of persons receiving early screening for diabetes. Of those with laboratory order claims, 53.1% underwent hemoglobin A1c testing, 30.0% underwent fasting glucose testing, and 16.9% underwent oral glucose tolerance testing. Compared with those who did not undergo early diabetes screening, those who did were more likely to be older; obese; having a history of gestational diabetes, chronic hypertension, polycystic ovarian syndrome, or hyperlipidemia; and having a family history of diabetes. In adjusted logistic regression, history of gestational diabetes (adjusted odds ratio 3.99; 95% confidence interval 3.73-4.26) had the strongest association with early diabetes screening. Adverse perinatal outcomes, including a higher rate of cesarean delivery, preterm delivery, preeclampsia, and gestational diabetes, occurred more frequently among women who underwent early diabetes screening. Conclusions: First-trimester early diabetes screening was mostly commonly performed by hemoglobin A1c evaluation, and persons who underwent early diabetes screening were more likely to experience adverse perinatal outcomes.

BACKGROUND: Infants receive their first bacteria from their birthing parent. This newly acquired microbiome plays a pivotal role in developing a robust immune system, the cornerstone of long-term health. RESULTS: We demonstrated that the gut, vaginal, and oral microbial diversity of pregnant women with SARS-CoV-2 infection is reduced, and women with early infections exhibit a different vaginal microbiota composition at the time of delivery compared to their healthy control counterparts. Accordingly, a low relative abundance of two Streptococcus sequence variants (SV) was predictive of infants born to pregnant women with SARS-CoV-2 infection. CONCLUSIONS: Our data suggest that SARS-CoV-2 infections during pregnancy, particularly early infections, are associated with lasting changes in the microbiome of pregnant women, compromising the initial microbial seed of their infant. Our results highlight the importance of further exploring the impact of SARS-CoV-2 on the infant's microbiome-dependent immune programming. Video Abstract.

OBJECTIVES: The ability to predict surgically relevant fetal renal hydronephrosis is limited. We sought to determine the most efficacious second- and third-trimester fetal renal pelvis anteroposterior diameter cutoffs to predict the need for postnatal surgery. METHODS: We retrospectively reviewed the medical records of mothers and neonates who had a prenatal sonographic examination in our Perinatal-Pediatric Urology Clinic and received follow-up care. Hydronephrosis was defined as a renal pelvis anteroposterior diameter of 5 mm or greater in the second trimester and 7 mm or greater in the third trimester. Hydronephrosis was subdivided into mild, moderate, and severe. RESULTS: Of 8453 fetuses, 96 met the criteria and were referred to our clinic. Isolated hydronephrosis was diagnosed in 74 fetuses, of which 53 received postnatal follow-up evaluations. The areas under the receiver operating characteristic curves for predicting postnatal surgery in the second and third trimesters were 0.770 and 0.899, respectively. The second-trimester renal anteroposterior diameter threshold that best predicted post-natal surgery was 9.5 mm (sensitivity, 71.4%; specificity, 81.1%). The third-trimester threshold that best predicted postnatal surgery was 15.0 mm (sensitivity, 85.7%; specificity, 94.6%). CONCLUSIONS: The fetal renal anteroposterior diameter on second- and third-trimester sonography is predictive of an increased risk for neonatal urologic surgery. Surgical risk is best predicted by a third-trimester renal anteroposterior diameter threshold of 15 mm.

OBJECTIVE: To investigate whether sonographic fetal head circumference (sfHC) size assessed by ultrasound prenatally could help predict OASIS. METHODS: This study is a retrospective cohort study between 2005 and 2016. Antenatal sfHC assessment, maternal demographics, and labor and delivery data were abstracted and compared in women with and without OASIS. RESULTS: Of 2057 pregnant women that had sfHC assessment, 121 (5.8%) had OASIS. In the unadjusted analysis, sfHC above the 90th centile was associated with OASIS (odds ratio [OR] 1.12; 95% confidence interval [CI] 1.02-1.23; P = 0.015). When adjusted for gestational age at delivery, maternal age, race, prolonged second stage, body mass index, infant gender, and intrapartum oxytocin use, sfHC above the 90th centile remained significantly associated with OASIS (OR 1.13, 95% CI 1.00-1.27, P = 0.050). CONCLUSION: In our cohort, sfHC above the 90th centile was associated with a greater risk of OASIS. As OASIS significantly impacts both short-term and long-term health outcomes, such as perineal pain, dyspareunia, and urinary and fecal incontinence, sfHC could be an additional prenatal marker to help clinicians counsel pregnant women about the risk of OASIS.

OBJECTIVES: Obesity is increasingly prevalent in the obstetric patient population, becoming one of the most commonly occurring risk factors in obstetric practice. Obesity has implications for maternal and fetal morbidity; in fact, some data suggest it is associated with higher rates of fetal anomaly. Coincident with this, maternal obesity poses an inherent challenge for ultrasound quality. The objective of this study is to investigate the relationship between ultrasound completion rates and advancing gestational age in obese gravidas, and to help identify an ideal gestational age to perform the second trimester ultrasound for fetal evaluation in the obese patient population. We hypothesized that in the obese patient, the odds of a completed scan would increase with each gestational age week, as fetal size increases. METHODS: This is a retrospective cohort study at a single tertiary care center. Inclusion criteria were pregnant women with BMI greater than 30 who had second trimester fetal ultrasound and delivery at our institution. Exclusion criteria were pregnancies without documented BMI, ultrasound not performed between 18 0/6 and 21 6/7 weeks, multiple gestations, or ultrasound performed for indication other than fetal anatomic assessment. Ultrasound reports were considered incomplete if they indicated suboptimal or non-visualization of any anatomic structures included in the comprehensive anatomic survey. Demographic data was compared using Student's t test and chi-square analysis where appropriate. Chi-square analysis was used to compare rates of completed surveys. p < .05 was considered significant. RESULTS: After application of eligibility criteria, our cohort included 1,954 subjects. When comparing subjects with a completed scan to those with an incomplete scan, there were more white subjects in the incomplete group (p = .012), but other analyzed demographics were similar between groups. When using 18 weeks as a referent group, with each additional completed week of gestation, subjects were more likely to have a completed scan, at 19 weeks (OR 1.29, CI 1.05-1.58); at 20 weeks (OR 1.46, CI 1.1-1.95); at 21 weeks (OR 2.12, CI 1.42-3.17) (p < .05 for each). This association persisted when adjusting for demographic factors. To identify the optimal timing for the second trimester ultrasound for fetal evaluation, we re-analyzed the data using each completed week of gestational age as the referent group. When using 19 weeks as the referent group, the odds of a complete scan were lower at 18 weeks, and higher at 21 weeks, but not different at 20 weeks. When using 20 weeks as the referent group, the odds of a complete scan were lower at 18 weeks, but not different at 19 or 21 weeks. Finally, when using 21 weeks as the referent group, the odds of a complete scan were lower at 18 and 19 weeks, but not different at 20 weeks. CONCLUSIONS: In this cohort of obese gravidas, the odds of having a completed anatomic survey continued to improve until 21 weeks gestational age. When comparing completed scans between each week, 18 weeks demonstrated consistently lower odds of a complete scan, however 20 weeks did not differ significantly from 19 weeks. Therefore, consideration should be made to perform the initial second trimester ultrasound for fetal evaluation in obese patients at 19 weeks gestational age to optimize completion rates while minimizing scans performed at advancing gestational ages.

OBJECTIVES: Hypertension during pregnancy is a leading cause of birthing parent mortality and adverse pregnancy outcomes. Since non-metropolitan communities face higher rates of several risk factors for hypertension in pregnancy and shortages in obstetrical services, persons residing in non-metropolitan areas may be at increased risk for adverse events compared to those living in metropolitan areas. Our study objectives were to examine by non-metropolitan vs. metropolitan birthing parent residence (1) the prevalence of chronic hypertension (cHTN) and hypertensive disorders of pregnancy (HDP), and (2) the prevalence of cesarean delivery, preterm birth, low birth weight, APGAR <7 at 5 min, NICU admission, and stillbirth/neonatal death among the group of birthing parents with cHTN and among the group of birthing parents with HDP. METHODS: Using U.S. Natality data from 2016 to 2018, we described the prevalence of cHTN and HDP and the association of each with several birthing parent and neonatal outcomes, stratified by non-metropolitan versus metropolitan county of birthing parent residence. Multivariable Poisson regression models were used to calculate adjusted prevalence ratios for these adverse outcomes. RESULTS: The prevalence of cHTN among pregnant individuals was 2.2% in non-metropolitan areas and 1.8% in metropolitan areas. For HDP, the prevalence was 7.4% in non-metropolitan areas and 6.6% in metropolitan areas. After adjusting for several sociodemographic characteristics among those with HDP, the prevalence ratio for an APGAR score < 7 at 5 min (aPR 1.34, 95% CI 1.29-1.38) and stillbirth/neonatal death (aPR 1.36, 95% CI 1.15-1.62) was increased among offspring born to birthing parents who resided in non-metropolitan counties. Similar results were seen among those with cHTN. CONCLUSIONS: The prevalence of cHTN and HDP is elevated among birthing parents residing in non-metropolitan areas. Also, the prevalence of APGAR <7 and stillbirth//neonatal death following pregnancies complicated by hypertension were higher among neonates born to birthing parents residing in non-metropolitan areas. Further research should investigate the robustness of these findings using alternate definitions of rural and urban areas and the possible link between low APGAR score, low NICU admission, and stillbirth/neonatal death among birthing parents residing in non-metropolitan counties.

OBJECTIVE: We evaluated the morbidity of Foley balloon for cervical ripening in comparison to oxytocin alone in women with a prior cesarean delivery. STUDY DESIGN: A four-hospital retrospective review of all women with viable singleton pregnancies and history of a single prior cesarean delivery presenting for cervical ripening between 1994 and 2015. Exposure groups were either Foley balloon or oxytocin, at the treating physician's discretion. The primary outcome was defined as maternal morbidity, evaluated by a composite that included hemorrhage, and/or uterine infection, and/or uterine rupture. We defined two secondary outcomes: neonatal morbidity, and vaginal delivery rate. Neonatal morbidity was evaluated by a composite that included five-minute APGAR score <7 and/or NICU admission. We adjusted results for potential confounding variables, including hospital site, maternal age and race, initial cervical dilation, and gestational age at delivery. RESULTS: We identified 688 patients who received ripening, 276 by Foley balloon and 412 by oxytocin. There was no significant difference in the primary outcome of maternal morbidity between groups: 38 (13.8%) in the Foley balloon group and 79 (19.2%) in the oxytocin group (aOR 1.43; 95% CI, 0.90-2.27). There was no significant difference in the secondary outcome of neonatal morbidity: 31 (11.3%) in the Foley balloon group and 51 (12.4%) in the oxytocin group (aOR 1.02; 95% CI, 0.57-1.80). The rate of vaginal delivery was significantly less in the Foley balloon group compared to the oxytocin group: 56.2% vs 64.1%, p = .037. CONCLUSION: When cervical ripening with either Foley balloon or oxytocin was utilized at the physician's discretion in women with prior cesarean, there was no identified difference in maternal and neonatal morbidity, but the rate of successful vaginal delivery was lower.

The risk of potential SARS-CoV-2 transmission by infected mothers during labor and delivery has not been investigated in-depth. This work collected air samples close to (respiratory droplets) and more distant from (aerosol generation) unvaccinated patients who had previously tested positive for SARS-CoV-2 during labor within 5 days of a positive test. All but one of the patients wore masks during the delivery, and delivery was carried out in either birthing or negative pressure isolation rooms. Our work failed to detect SARS-CoV-2 RNA in any air samples for all of the six patients who gave birth vaginally, despite validation of the limit of detection of the samplers. In sum, this brief report provides initial evidence that the risk of airborne transmission of SARS-CoV-2 during labor may be mitigated by the use of masks and high ventilation rates common in many modern U.S. medical facilities; however more work is needed to fully evaluate the risk of SARS-CoV-2 transmission during labor and maternal pushing.

Mitral valve prolapse (MVP) is the most common valvular heart disease in women of reproductive age. Whether MVP increases the likelihood of adverse outcomes in pregnancy is unknown. The study objective was to examine the cardiac and obstetric outcomes associated with MVP in pregnant women. This retrospective cohort study, using the Healthcare Cost and Utilization Project National Readmission Sample database between 2010 and 2017, identified all pregnant women with MVP using the International Classification of Disease, Ninth and Tenth Revisions codes. The maternal cardiac and obstetric outcomes in pregnant women diagnosed with MVP were compared with women without MVP using multivariable logistic and Cox proportional hazard regression models adjusted for baseline demographic characteristics. There were 23,000 pregnancy admissions with MVP with an overall incidence of 16.9 cases per 10,000 pregnancy admissions. Pregnant women with MVP were more likely to die during pregnancy (adjusted hazard ratio 5.13, 95% confidence interval [CI] 1.09 to 24.16), develop cardiac arrest (adjusted odds ratio [aOR] 4.44, 95% CI 1.04 to 18.89), arrhythmia (aOR 10.96, 95% CI 9.17 to 13.12), stroke (aOR 6.90, 95% CI 1.26 to 37.58), heart failure (aOR 5.81, 95% CI 3.84 to 8.79), or suffer a coronary artery dissection (aOR 25.22, 95% CI 3.42 to 186.07) compared with women without MVP. Pregnancies with MVP were also associated with increased risks of preterm delivery (aOR 1.21, 95% CI 1.02 to 1.44) and preeclampsia/hemolysis, elevated liver enzymes, and low platelets syndrome (aOR 1.22, 95% CI 1.05 to 1.41). In conclusion, MVP in pregnancy is associated with adverse maternal cardiac outcomes and higher obstetric risks.

PURPOSE: Examine risks of intrauterine growth restriction (IUGR) and composite perinatal outcomes with estimated fetal weights (EFW) 10-20th%, and compare outcomes using umbilical artery Doppler (UAD). MATERIALS AND METHODS: Retrospective, cohort evaluating ultrasound (US) EFW 10-20th%, between 2002 and 2012. Cases were identified with EFW % 10-20. Controls, EFW >20th% were obtained for each case, matched by gestational age, and US date. Unadjusted and adjusted logistic regression was used for outcomes. RESULTS: Seven hundred and sixty-seven cases met criteria with matched controls. Fetuses having EFW 10-20th% (GA 33.6 ± 3.7 weeks) had increased IUGR on follow up ultrasound (OR 26.5[10.2-68.7], p < .01), small for gestational age (SGA) (OR 9.2 [6.9-12.3], p < .01), neonatal intensive care unit (NICU) admissions (OR 2.4 [1.6-3.6], p < .01), and composite perinatal morbidity (OR 7.8 [6.0-10.1], p < .01) on adjusted analyses. Abnormal UAD in cases had greater rates of 5 min Apgar <7, NICU admission and composite morbidity (p < .05). CONCLUSIONS: Pregnancies with EFW 10-20th% at the time of initial US are at increased risk for developing IUGR and being SGA at birth, with more NICU admissions and composite perinatal outcomes; abnormal UAD evaluation in cases conveyed further increase in outcomes.

Adolescent pregnancy, although on the decline, represents a significant public health concern. Often adolescents present late to prenatal care, either from lack of knowledge, fear of consequences, limited access, stigma, or all of the above. Although multifaceted, there are many risks both to mother and child that are increased in adolescent pregnancy. Many are unintended and are at risk for repeat adolescent pregnancy, especially within the first 2 years. Risks include but are not limited to: low birth weight, preterm delivery, stillbirth, and preeclampsia, as well as feelings of social isolation, delayed or neglected educational goals, and maternal depression.
