RESUMO
OBJECTIVE: Pregnancy outcomes of individuals receiving cervical cerclage when the cervix is dilated are not well known. We sought to examine preterm birth rates after ultrasound or physical examination-indicated cerclage placement according to the degree of cervical dilation. STUDY DESIGN: This was a retrospective cohort study of individuals with singleton pregnancies undergoing ultrasound or physical examination-indicated cerclage before 240/7 weeks of gestation from 2004 to 2018. Individuals were categorized based on the degree of cervical dilation at the time of cerclage. Our primary outcome was preterm delivery at less than 37 weeks of gestation. Multivariable logistic regression was performed to calculate adjusted odds ratios (aOR) with 95th confidence intervals (95% CI), controlling for predefined covariates. RESULTS: Of 147 individuals undergoing ultrasound or physical examination-indicated cerclage, 90/147 (61%) had a closed or 0.5 cm dilated cervix at the time of cerclage placement, 45/147 (31%) had a cervical dilation of 1 to 2.5 cm, and 12/147 (8%) had a cervical dilation of 3 to 4 cm at the time of placement. Individuals with a cervical dilation of 1 to 2.5 cm compared with those who had a closed cervix did not have increased odds of preterm delivery (58 vs. 42%; aOR: 1.95; 95% CI: 0.93-4.07). However, individuals with a cervical dilation of 3 to 4 cm compared with individuals who had a closed cervix had significantly increased odds of preterm delivery (75 vs. 42%; aOR: 4.33; 95% CI: 1.05-17.77). CONCLUSION: The rate of preterm birth increases with increasing cervical dilation at the time of cerclage placement. However, individuals who have a cerclage placed when the cervix is 1 to 2.5 cm can achieve an outcome that is not significantly different from those who had a cerclage placed when the cervix is closed. KEY POINTS: · Time from cerclage placement to delivery decreases as cervical dilation increases.. · Individuals 1 to 2.5 cm dilated at the time of cerclage can achieve a favorable outcome.. · A cervical dilation of ≥3 cm at cerclage placement was associated with extreme prematurity..

OBJECTIVE: This study aimed to evaluate rates of superimposed preeclampsia in pregnant individuals with echocardiography-diagnosed cardiac geometric changes in the setting of chronic hypertension. STUDY DESIGN: This was a retrospective study of pregnant individuals with chronic hypertension who delivered singleton pregnancies at 20 weeks' gestation or greater at a tertiary care center. Analyses were limited to individuals who had an echocardiogram during any trimester. Cardiac changes were categorized as normal morphology, concentric remodeling, eccentric hypertrophy, and concentric hypertrophy according to the American Society of Echocardiography guidelines. Our primary outcome was early-onset superimposed preeclampsia defined as delivery at less than 34 weeks' gestation. Other secondary outcomes were also examined. Adjusted odds ratios (aORs) with 95% confidence intervals (95% CIs) were calculated, controlling for prespecified covariates. RESULTS: Of the 168 individuals who delivered from 2010 to 2020, 57 (33.9%) had normal morphology, 54 (32.1%) had concentric remodeling, 9 (5.4%) had eccentric hypertrophy, and 48 (28.6%) had concentric hypertrophy. Non-Hispanic black individuals presented over 76% of the cohort. Rates of the primary outcome in individuals with normal morphology, concentric remodeling, eccentric hypertrophy, and concentric hypertrophy were 15.8, 37.0, 22.2, and 41.7%, respectively (p = 0.01). Compared with individuals with normal morphology, individuals with concentric remodeling were more likely to have the primary outcome (aOR: 3.28; 95% CI: 1.28-8.39), fetal growth restriction (crude OR: 2.98; 95% CI: 1.05-8.43), and iatrogenic preterm delivery <34 weeks' gestation (aOR: 2.72; 95% CI: 1.15-6.40). Compared with individuals with normal morphology, individuals with concentric hypertrophy were more likely to have the primary outcome (aOR: 4.16; 95% CI: 1.57-10.97), superimposed preeclampsia with severe features at any gestational age (aOR: 4.75; 95% CI: 1.94-11.62), iatrogenic preterm delivery <34 weeks' gestation (aOR: 3.60; 95% CI: 1.47-8.81), and neonatal intensive care unit admission (aOR: 4.82; 95% CI: 1.90-12.21). CONCLUSION: Concentric remodeling and concentric hypertrophy were associated with increased odds of early-onset superimposed preeclampsia. KEY POINTS: · Concentric remodeling and concentric hypertrophy were associated with an increased risk of superimposed preeclampsia.. · Concentric hypertrophy was associated with an increased risk of delivery at less than 34 weeks.. · Two-thirds of the individuals in our study had concentric hypertrophy and concentric remodeling..

Antenatal diagnosis of placenta accreta spectrum (PAS) improves maternal and neonatal outcomes by allowing for multidisciplinary planning and preparedness. Ultrasound is the primary imaging tool. Simplification and standardization of placental evaluation and reporting terminology allows improved communication and understanding between teams. Prior to 10 weeks of gestation, gestational sac position and least myometrial thickness surrounding the gestational sac help PAS diagnosis very early in pregnancy. Late first-, second-, and third-trimester evaluation includes comprehensive evaluation of the placenta, transabdominal and transvaginal with partially full maternal urinary bladder, and by color Doppler. Subsequently, the sonologist should indicate whether the evaluation was optimal or suboptimal; the level of suspicion as low, moderate, or high; and the extent as focal, global, or extending beyond the uterus. Other complementary imaging modalities such as 3D-power Doppler ultrasound, magnetic resonance imaging (MRI), and vascular topography mapping strive to improve antenatal placental evaluation but remain investigational at present. KEY POINTS: · Antenatal imaging, primarily using ultrasound with partially full maternal urinary bladder, is an essential means of evaluation of those at risk for PAS.. · Simplification and standardization of placental evaluation and reporting will allow improved communication between the multidisciplinary teams.. · Gestational sac location prior to 10 weeks of gestation and four markers after that (placental lacunae and echostructure, myometrial thinning, hypoechoic zone with or without bulging between placenta and myometrium, and increased flow on color Doppler)..

AIM: The objective of this study was to compare neonatal and maternal outcomes among women with two previous cesarean deliveries who undergo trial of labor after two cesarean section (TOLA2C) versus elective repeat cesarean delivery (ERCD). Our primary outcome was neonatal intensive care unit (NICU) admission. Secondary outcomes included APGAR score <7 at 5 min, TOLA2C success rate, uterine rupture, postpartum hemorrhage, maternal blood transfusion, maternal bowel and bladder injury, immediate postpartum infection, and maternal mortality. METHODS: This retrospective cohort study was undertaken at a community medical center from January 1, 2008 to December 31, 2018. Inclusion criteria were women with a vertex singleton gestation at term and a history of two prior cesarean sections. Exclusion criteria included a previous successful TOLA2C, prior classical uterine incision or abdominal myomectomy, placenta previa or invasive placentation, multiple gestation, nonvertex presentation, history of uterine rupture or known fetal anomaly. Maternal and neonatal outcomes were assessed using Fisher exact test and Wilcoxon rank sum test. RESULTS: A total of 793 patients fulfilled study criteria. There were no differences in neonatal intensive care unit admissions or 5-min APGAR scores <7 between the two groups. Sixty-eight percent of women who underwent TOLAC (N = 82) had a successful vaginal delivery. The uterine rupture rate was 1.16% (N = 1) in the TOLA2C group with no case of uterine rupture in the ERCD group. No difference in maternal morbidity was noted between the two groups. No maternal or neonatal mortalities occurred in either group. CONCLUSIONS: There was no difference in maternal or neonatal morbidity among patients in our study population with two previous cesarean sections who opted for TOLA2C versus ERCD.

BACKGROUND: Many cases of placenta accreta spectrum are not diagnosed antenatally, despite identified risk factors and improved imaging methods. Identification of plasma protein biomarkers could further improve the antenatal diagnosis of placenta accreta spectrum . OBJECTIVE: The purpose of this study was to determine if women with placenta accreta spectrum have a distinct plasma protein profile compared with control subjects. STUDY DESIGN: We obtained plasma samples before delivery from 16 participants with placenta accreta spectrum and 10 control subjects with similar gestational ages (35.1 vs 35.5 weeks gestation, respectively). We analyzed plasma samples with an aptamer-based proteomics platform for alterations in 1305 unique proteins. Heat maps of the most differentially expressed proteins (T test, P<.01) were generated with matrix visualization and analysis software. Principal component analysis was performed with the use of all 1305 proteins and the top 21 dysregulated proteins. We then confirmed dysregulated proteins using enzyme-linked immunosorbent assay and report significant differences between placenta accreta spectrum and control cases (Wilcoxon-rank sum test, P<.05). RESULTS: Many of the top 50 proteins that significantly dysregulated in participants with placenta accreta spectrum were inflammatory cytokines, factors that regulate vascular remodeling, and extracellular matrix proteins that regulate invasion. Placenta accreta spectrum, with the use of the top 21 proteins, distinctly separated the placenta accreta spectrum cases from control cases (P<.01). Using enzyme-linked immunosorbent assay, we confirmed 4 proteins that were dysregulated in placenta accreta spectrum compared with control cases: median antithrombin III concentrations (240.4 vs 150.3 mg/mL; P=.002), median plasminogen activator inhibitor 1 concentrations (4.1 vs 7.1 ng/mL; P<.001), soluble Tie2 (13.5 vs 10.4 ng/mL; P=.02), soluble vascular endothelial growth factor receptor 2 (9.0 vs 5.9 ng/mL; P=.003). CONCLUSION: Participants with placenta accreta spectrum had a unique and distinct plasma protein signature.

OBJECTIVE: To evaluate whether real-time continuous glucose monitoring improves glycemic control over intermittent self-monitoring of blood glucose in gestational diabetes. STUDY DESIGN: We performed a single-institution randomized controlled trial. Patients with gestational diabetes were randomized to use either real-time or blinded continuous glucose monitoring. The primary outcome was mean sensor glucose level during the fourth week of continuous glucose monitoring use. Secondary outcomes included glycemic control and a composite of obstetric and neonatal outcomes. RESULTS: Of the 40 enrolled patients, 12 (60%) patients in the blinded continuous glucose monitoring group and 11 (55%) in the real-time continuous glucose monitoring group completed 4 weeks of monitoring and were included in the final analysis. There was no significant difference in mean sensor glucose level between the blinded continuous glucose monitoring group (98.9 ± 8.9 mg/dL) and the real-time continuous glucose monitoring group (107.5 ± 11.4 mg/dL). There were also no significant differences in the time spent in glycemic target, maternal, or neonatal outcomes. CONCLUSION: Our study shows that the use of continuous glucose monitoring with real-time feedback did not significantly decrease mean glucose values compared with intermittent self-monitoring of blood glucose after 4 weeks of continuous glucose monitoring use.

The Beyond Ultrasound First Forum was conceived to increase awareness that the quality of obstetric and gynecologic ultrasound can be improved, and is inconsistent throughout the country, likely due to multiple factors, including the lack of a standardized curriculum and competency assessment in ultrasound teaching. The forum brought together representatives from many professional associations; the imaging community including radiology, obstetrics and gynecology, and emergency medicine among others; in addition to government agencies, insurers, industry, and others with common interest in obstetric and gynecologic ultrasound. This group worked together in focus sessions aimed at developing solutions on how to standardize and improve ultrasound training at the resident level and beyond. A new curriculum and competency assessment program for teaching residents (obstetrics and gynecology, radiology, and any other specialty doing obstetrics and gynecology ultrasound) was presented, and performance measures of ultrasound quality in clinical practice were discussed. The aim of this forum was to increase and unify the quality of ultrasound examinations in obstetrics and gynecology with the ultimate goal of improving patient safety and quality of clinical care. This report describes the proceedings of this conference including possible approaches to resident teaching and means to improve the inconsistent quality of ultrasound examinations performed today.

BACKGROUND: The association between small-for-gestational-age (birthweight <10th percentile for gestational age) and neonatal morbidity is well established. Yet, there is a paucity of data on the relationship between suspected small for gestational age (sonographic-estimated fetal weight <10th percentile) at 2 thresholds and subsequent neonatal morbidity. OBJECTIVE: The objective of this study was to determine the relationship between sonographic-estimated fetal weight <5th percentile vs 5-9th percentile and neonatal morbidity. STUDY DESIGN: This retrospective study involved 5 centers and included nonanomalous, singletons with sonographic-estimated fetal weight <10th percentile for gestational age who delivered from 2009-2012. Composite neonatal morbidity included respiratory distress syndrome, proven sepsis, intraventricular hemorrhage grade III or IV, necrotizing enterocolitis, thrombocytopenia, seizures, or death. Odd ratios were adjusted for center, maternal age, race, body mass index at first visit, smoking status, use of alcohol, use of drugs, and neonatal gender. RESULTS: Of 834 women with suspected small-for-gestational-age fetuses, 513 (62%) had sonographic-estimated fetal weight <5th percentile, and 321 (38%) had sonographic-estimated fetal weight of 5-9th percentile for gestational age. At delivery, 81% of women with a suspected small-for-gestational-age fetus had a confirmed small-for-gestational-age fetus. In the group with a sonographic-estimated fetal weight <5th percentile, 59% of neonates had birthweight <5th percentile; in the group with a sonographic-estimated fetal weight 5-9th percentile, 41% had birthweight <5th percentile, and 36% had birthweight at 5-9th percentile. Neonatal intensive care unit admission differed significantly for those fetuses at <5th percentile (29%) compared with those fetuses at 5-9th percentile (15%; P<.001). The composite neonatal morbidity among the sonographic-estimated fetal weight <5th percentile group was higher than the sonographic-estimated fetal weight of 5-9th percentile group (31% vs 13%; adjusted odds ratio, 2.41; 95% confidence interval, 1.53-3.80). Similar findings were noted when the analysis was limited to sonographic-estimated fetal weight within 28 days of delivery (adjusted odds ratio, 2.22; 95% confidence interval, 1.34-3.67). CONCLUSION: Eight of 10 suspected small-for-gestational-age fetuses had birthweight <10th percentile for gestational age; the prediction of actual birthweight was more accurate in the <5th percentile group. Neonates with sonographic-estimated fetal weight of <5th percentile were more likely to be admitted to the neonatal intensive care unit and have complications than were those neonates with sonographic-estimated fetal weight of 5-9th percentile.

Ultrasound technology has evolved dramatically in recent years and now includes applications such as 3-dimensional volume imaging, real-time evaluation of pelvic organs (simultaneous with the physical examination), and Doppler blood flow mapping without the need for contrast, which makes ultrasound imaging unique for imaging the female pelvis. Among the many cross-sectional imaging techniques, we should use the most informative, less invasive, and less expensive modality to avoid radiation when possible. Hence, ultrasound imaging should be the first imaging modality used in women with pelvic symptoms.

Placenta accreta spectrum is one of the most morbid conditions obstetricians will encounter. The incidence has dramatically increased in the last 20 years. The major contributing factor to this is believed to be the increase in the rate of cesarean delivery. Despite the increased incidence of placenta accreta, most obstetricians have personally managed only a small number of women with placenta accreta. The condition poses dramatic risk for massive hemorrhage and associated complication such as consumption coagulopathy, multisystem organ failure, and death. In addition, there is an increased risk for surgical complications such as injury to bladder, ureters, and bowel and the need for reoperation. Most women require blood transfusion, often in large quantities, and many require admission to an intensive care unit. As a result of indicated, often emergent preterm delivery, many babies require admission to a neonatal care intensive care unit. Outcomes are improved when delivery is accomplished in centers with multidisciplinary expertise and experience in the care of placenta accreta. Such expertise may include maternal-fetal medicine, gynecologic surgery, gynecologic oncology, vascular, trauma and urologic surgery, transfusion medicine, intensivists, neonatologists, interventional radiologists, anesthesiologists, specialized nursing staff, and ancillary personnel. This article highlights the desired features for a center of excellence in placenta accreta, and which patients should be referred for evaluation and/or delivery in such centers.

Noninvasive prenatal testing (NIPT) has had a profound influence in the field of prenatal diagnosis since the 1997 discovery of cell-free fetal DNA in maternal blood. Research has progressed rapidly, with clinical data supporting laboratory studies showing that NIPT is highly sensitive and specific for fetal aneuploidy, resulting in marked uptake in the high-risk patient population. The superior accuracy of NIPT compared with conventional screening methods has led to significant decreases in the number of invasive diagnostic procedures, in addition to a concomitant decrease in the number of procedure-related fetal losses. Yet, NIPT has been described as a 'disruptive innovation' due to the considerable changes the technology has commanded on current prenatal screening and diagnostic practices. This review summarizes both institutional and global experience with NIPT uptake, its effect on reducing diagnostic invasive procedures, and the unique challenges that reduced procedural volume may have on physician and trainee proficiency, cytogenetic laboratories, and neonatal outcome.

OBJECTIVES: To report changes in the use of the combined first-trimester screen (FTS) in patients classified as high and low risk for fetal aneuploidy, including after introduction of noninvasive prenatal testing (NIPT). METHODS: A prospectively collected database was reviewed to investigate changes in FTS use before and after American College of Obstetricians and Gynecologists (ACOG) Practice Bulletin No. 77 (Obstet Gynecol 2007; 109:217-227), which recommended that all patients be offered aneuploidy screening, and after NIPT introduction. High-risk patients were classified as 35 years or older at the estimated time of delivery or those with an abnormal prior screen, abnormal ultrasound findings, or family history of aneuploidy. Data were normalized per 100 morphologic ultrasound examinations to account for changes in patient number over time. Statistical significance was defined as P < .05. RESULTS: A total of 10,125 FTSs were recorded during the 88-month study period, including 2962 in high-risk patients and 7163 in low-risk patients. The total number of FTSs performed per 100 morphologic ultrasound examinations significantly increased after ACOG Practice Bulletin No. 77 and significantly decreased after NIPT introduction. In high-risk patients, the total number of FTSs performed per 100 morphologic ultrasound examinations significantly increased after ACOG Practice Bulletin No. 77 but significantly decreased after NIPT introduction. In contrast, in low-risk patients, the total number of FTSs performed per 100 morphologic ultrasound examinations significantly increased after ACOG Practice Bulletin No.77 but was not statistically different after NIPT introduction. CONCLUSIONS: American College of Obstetricians and Gynecologists Practice Bulletin No. 77 significantly increased patient use of FTS. The introduction of NIPT significantly decreased FTS use in the high-risk population but not in the low-risk population.

OBJECTIVE: The purpose of this review was to determine the likelihood of malignancy or complications with ultrasonographic diagnosis of adnexal masses in pregnancy and to evaluate the obstetrical outcomes. Materials and METHODS: A review of literature was performed using keywords "adnexal mass and pregnancy" or "ovarian mass and pregnancy." RESULTS: Out of the 340 abstracts reviewed, 313 were excluded. The incidence of adnexal mass in pregnancy varied from 0.1 to 2.4%, with an average of 0.02%. Regarding the likelihood of malignancy, in seven publications, there were 557 women with 563 adnexal masses. Of these 563 masses, 48% were classified as simple and 52% as complex. Among the simple masses, 1% were malignant. Among the complex masses, 9% were malignant. When comparing laparoscopy and laparotomy, the rate of preterm contractions was found to be higher in patients undergoing laparotomy and this was statistically significant. Other measures, such as spontaneous abortion, vaginal bleeding, < 37 week delivery, and intrauterine fetal demise, were not found to have a significant difference. CONCLUSION: Adnexal masses in pregnancy occur infrequently and depending on whether the surgery was performed emergently or electively, via laparoscopy or laparotomy, the outcomes will vary.

OBJECTIVE: Noninvasive prenatal testing (NIPT) is a recently developed risk-assessment technique with high sensitivity and specificity for fetal aneuploidy. The effect NIPT has had on traditional screening and diagnostic testing has not been clearly demonstrated. In this study, NIPT uptake and subsequent changes in the utilization of first-trimester screen (FTS), chorionic villus sampling (CVS), and amniocentesis in a single referral center is reported. STUDY DESIGN: Monthly numbers of NIPT (in high-risk patients), FTS, CVS, and amniocentesis were compared between a 35-month baseline period (April 2009 through February 2012) before introduction of NIPT, and the initial 16 months following NIPT introduction divided in 4-month quarters beginning in March 2012 through June 2013. RESULTS: A total of 1265 NIPT, 6637 FTS, 251 CVS, and 1134 amniocentesis were recorded over the 51-month study period in singleton pregnancies of women who desired prenatal screening and diagnostic testing. NIPT became the predominant FTS method by the second quarter following its introduction, increasing by 55.0% over the course of the study period. Total first-trimester risk assessments (NIPT+FTS) were not statistically different following NIPT (P = .312), but average monthly FTS procedures significantly decreased following NIPT introduction, decreasing by 48.7% over the course of the study period. Average monthly CVS and amniocentesis procedures significantly decreased following NIPT introduction, representing a 77.2% and 52.5% decrease in testing, respectively. Screening and testing per 100 morphological ultrasounds followed a similar trend. CONCLUSION: NIPT was quickly adopted by our high-risk patient population, and significantly decreased alternate prenatal screening and diagnostic testing in a short period of time.

OBJECTIVES: The aim of this pilot study was to measure the angle of rotation of the uterus at the fundus from horizontal using 3-dimensional sonography in women presenting for annual gynecologic examinations. METHODS: A total of 51 patients participated in the study. All patients underwent transvaginal sonography, and 3-dimensional volumes were acquired. The cervicouterine angle and the angle of rotation at the fundus were measured. RESULTS: The uteri were noted to be anteverted in 64.7%, retroverted in 25.5%, and euverted in 9.8%. They were noted to be pointing toward the right side of the pelvis in 49.0%, to the left side in 39.2%, and at the midline in 11.8%. The median cervicouterine angle was 122° (interquartile range [IQR], 105°-137°). The median angle of rotation at the fundus away from horizontal in either a clockwise or counterclockwise direction on the transverse B-plane was 10.4° (IQR, 7.1°-19.0°), with a maximal angle of 43°, and on the coronal C-plane, it was 10.0° (IQR, 3.0°-20.0°), with a maximal angle of 43°. Noneuverted uteri were more likely to be rotated at the fundus. CONCLUSIONS: Our study reveals that, contrary to traditional thinking, the uterus can be rotated at the fundus in relation to the body (z-axis) along the longitudinal axis of the cervical canal.
