RESUMO
BACKGROUND: The 22q11.2 deletion syndrome is the most common microdeletion syndrome and is frequently associated with congenital heart disease. Prenatal diagnosis of 22q11.2 deletion syndrome is increasingly offered. It is unknown whether there is a clinical benefit to prenatal detection as compared with postnatal diagnosis. OBJECTIVE: This study aimed to determine differences in perinatal and infant outcomes between patients with prenatal and postnatal diagnosis of 22q11.2 deletion syndrome. STUDY DESIGN: This was a retrospective cohort study across multiple international centers (30 sites, 4 continents) from 2006 to 2019. Participants were fetuses, neonates, or infants with a genetic diagnosis of 22q11.2 deletion syndrome by 1 year of age with or without congenital heart disease; those with prenatal diagnosis or suspicion (suggestive ultrasound findings and/or high-risk cell-free fetal DNA screen for 22q11.2 deletion syndrome with postnatal confirmation) were compared with those with postnatal diagnosis. Perinatal management, cardiac and noncardiac morbidity, and mortality by 1 year were assessed. Outcomes were adjusted for presence of critical congenital heart disease, gestational age at birth, and site. RESULTS: A total of 625 fetuses, neonates, or infants with 22q11.2 deletion syndrome (53.4% male) were included: 259 fetuses were prenatally diagnosed (156 [60.2%] were live-born) and 122 neonates were prenatally suspected with postnatal confirmation, whereas 244 infants were postnatally diagnosed. In the live-born cohort (n=522), 1-year mortality was 5.9%, which did not differ between groups but differed by the presence of critical congenital heart disease (hazard ratio, 4.18; 95% confidence interval, 1.56-11.18; P<.001) and gestational age at birth (hazard ratio, 0.78 per week; 95% confidence interval, 0.69-0.89; P<.001). Adjusting for critical congenital heart disease and gestational age at birth, the prenatal cohort was less likely to deliver at a local community hospital (5.1% vs 38.2%; odds ratio, 0.11; 95% confidence interval, 0.06-0.23; P<.001), experience neonatal cardiac decompensation (1.3% vs 5.0%; odds ratio, 0.11; 95% confidence interval, 0.03-0.49; P=.004), or have failure to thrive by 1 year (43.4% vs 50.3%; odds ratio, 0.58; 95% confidence interval, 0.36-0.91; P=.019). CONCLUSION: Prenatal detection of 22q11.2 deletion syndrome was associated with improved delivery management and less cardiac and noncardiac morbidity, but not mortality, compared with postnatal detection.

BACKGROUND: Over half of all pregnancies in the United States are unintended, and 18% result in termination of pregnancy (TOP). Some women seek TOP, but ultimately continue their pregnancy. Data are limited about their utilization of prenatal care and their perinatal outcomes. Our primary outcome was to investigate differences in guideline-based prenatal care utilization in women who consider but do not have an abortion. METHODS: Retrospective cohort study of patients having obstetrical dating ultrasound (US) from 2011-2018 at a single academic medical center that offers TOP. Contemplators completed US with intention of TOP but instead continued the pregnancy to live birth. A 2:1 group of non-contemplators completed US and continued to live birth. A prenatal care utilization scoring system was used to compare groups. Secondary outcomes investigated differences in adverse pregnancy outcomes and postpartum care. RESULTS: There were 94 contemplators and 183 non-contemplators. Inadequate prenatal care utilization initially was more common in contemplators than non-contemplators (62.8% vs 85.8%, p < 0.01) but was not significant after adjustment (aOR 1.0, 95% CI 0.40 - 2.56). There were no differences in adverse obstetric or neonatal outcomes. Contemplators were significantly more likely to have a postpartum contraceptive method (PPCM) upon hospital discharge (aOR 4.8, 95% CI 1.16 - 20.0) and significantly more likely to use a highly-effective PPCM (aOR 6.4, 95% CI 2.34 - 17.4). CONCLUSIONS: Reversal of intention for TOP is not associated with differences in prenatal care utilization, but is associated with increased uptake of postpartum contraceptive method.

BACKGROUND: Ninety-four percent of all maternal deaths occur in low- and middle-income countries, and the majority are preventable. Access to quality Obstetric ultrasound can identify some complications leading to maternal and neonatal/perinatal mortality or morbidity and may allow timely referral to higher-resource centers. However, there are significant global inequalities in access to imaging and many challenges to deploying ultrasound to rural areas. In this study, we tested a novel, innovative Obstetric telediagnostic ultrasound system in which the imaging acquisitions are obtained by an operator without prior ultrasound experience using simple scan protocols based only on external body landmarks and uploaded using low-bandwidth internet for asynchronous remote interpretation by an off-site specialist. METHODS: This is a single-center pilot study. A nurse and care technician underwent 8 h of training on the telediagnostic system. Subsequently, 126 patients (68 second trimester and 58 third trimester) were recruited at a health center in Lima, Peru and scanned by these ultrasound-naïve operators. The imaging acquisitions were uploaded by the telemedicine platform and interpreted remotely in the United States. Comparison of telediagnostic imaging was made to a concurrently performed standard of care ultrasound obtained and interpreted by an experienced attending radiologist. Cohen's Kappa was used to test agreement between categorical variables. Intraclass correlation and Bland-Altman plots were used to test agreement between continuous variables. RESULTS: Obstetric ultrasound telediagnosis showed excellent agreement with standard of care ultrasound allowing the identification of number of fetuses (100% agreement), fetal presentation (95.8% agreement, κ =0.78 (p < 0.0001)), placental location (85.6% agreement, κ =0.74 (p < 0.0001)), and assessment of normal/abnormal amniotic fluid volume (99.2% agreement) with sensitivity and specificity > 95% for all variables. Intraclass correlation was good or excellent for all fetal biometric measurements (0.81-0.95). The majority (88.5%) of second trimester ultrasound exam biometry measurements produced dating within 14 days of standard of care ultrasound. CONCLUSION: This Obstetric ultrasound telediagnostic system is a promising means to increase access to diagnostic Obstetric ultrasound in low-resource settings. The telediagnostic system demonstrated excellent agreement with standard of care ultrasound. Fetal biometric measurements were acceptable for use in the detection of gross discrepancies in fetal size requiring further follow up.

Billions of people around the world lack access to diagnostic imaging. To address this issue, we piloted a comprehensive ultrasound telediagnostic system, which uses ultrasound volume sweep imaging (VSI) acquisitions capable of being performed by operators without prior traditional ultrasound training and new telemedicine software capable of sending imaging acquisitions asynchronously over low Internet bandwidth for remote interpretation. The telediagnostic system was tested with obstetric, right upper quadrant abdominal, and thyroid volume sweep imaging protocols in Peru. Scans obtained by operators without prior ultrasound experience were sent for remote interpretation by specialists using the telemedicine platform. Scans obtained allowed visualization of the target region in 96% of cases with diagnostic imaging quality. This telediagnostic system shows promise in improving health care disparities in the developing world.

OBJECTIVE: To determine whether prenatal ultrasound measurement of fetal stomach size, as a surrogate marker of fetal swallowing, is predictive of postnatal development of gastroesophageal reflux disease (GERD) in cases of isolated cleft lip and/or palate (CL/P). DESIGN: This is a retrospective case-control study. The outcome of interest is postnatal diagnosis of GERD in isolated CL/P. The exposure of interest is prenatal stomach size measurement by ultrasound. SETTING: The study population was selected from an academic, tertiary care center between 2003 and 2011. PATIENTS/PARTICIPANTS: Cases were neonates undergoing CL/P repair during the study period. Cases with other known structural or chromosomal abnormalities were excluded. Controls were contemporary, nondiabetic neonates that matched gestational age (within one week) to cases. Each case measurement was matched â¼1:2 with control measurement. INTERVENTIONS: None. MAIN OUTCOME MEASURE: The primary outcome was difference in mean prenatal ultrasound measurement of fetal stomach size between cases and controls. We hypothesized that patients with postnatal development of GERD would have smaller mean fetal stomach size. RESULTS: There were 32 cases including 19 patients with unilateral cleft lip and palate, 8 with unilateral cleft lip, and 4 with bilateral cleft lip and palate. Cases were noted to have smaller mean anterior-posterior and transverse fetal stomach measurements as compared to controls. This was statistically significant from 16 to 21 weeks, 25 to 27 weeks, and 28 to 36 weeks (P < .01 for all). CONCLUSIONS: Prenatal ultrasound measurement of fetal stomach size as a surrogate marker of fetal swallowing is predictive of postnatal development of GERD in isolated CL/P.

BACKGROUND: Point-of-care ultrasound (POC-US) is a diagnostic test conducted at the site of patient care with direct interpretation by the clinician, providing immediate results. POC-US for gynecologic application is not well characterized by current literature yet has the potential to increase access in limited resource settings. We compared the diagnostics of three POC-US devices for gynecologic (GYN) pathology and then performed evaluation of sensitivity and specificity of a single best POC-US device for intended use in a low resource setting. METHODS: This is prospective, pilot descriptive study of 60 subjects. In part 1, comparison of three POC-US devices was performed. Twenty subjects underwent POC-US with three test units [GE Vscan (Vscan), Sonosite Iviz (Iviz), Philips Lumify (Lumify)] followed by diagnostic ultrasound (Dx-US) for reference imaging. Image quality and correlation for devices was scored by blinded reviewers and quantitative measurements of GYN pathology were compared. In part 2, forty subjects underwent POC-US validation with the highest scoring device (Lumify) and Dx-US for reference imaging. Concordance of POC-US operator-interpreted diagnosis with reference imaging interpretation were assessed by Cohen's unweighted kappa coefficient. Accuracy and agreement of POC-US were assessed by linear regression and Bland-Altman plot analysis. Sensitivity and specificity of POC-US for gynecologic pathologies were calculated. RESULTS: In aggregate qualitative measurements, Lumify and Iviz units performed superiorly to Vscan. There was no statistically significant difference in quantitative measurements between devices, but a trend towards lower mean error was seen for Lumify and Iviz as compared to Vscan. Lumify device had highest overall scoring and was selected for further testing. In validation comparison of Lumify to Dx-US, no statistically significant differences were found for measurements of endometrium, uterus, ovaries, adnexal pathology, or leiomyomata, (P < 0.02) with excellent agreement in operator-interpreted diagnosis (Kappa > 0.7). Sensitivity and specificity of detecting pathology was 80-100% with PPV and NPV 76-100%. CONCLUSION: Among three POC-US devices, Lumify and Iviz devices show highest potential for successful application to clinical gynecologic ultrasound. Clinician-performed POC-US has high diagnostic accuracy, sensitivity, and specificity for basic GYN anatomy and pathology. POC-US is an acceptable and feasible diagnostic tool with potential for future application in a low resource setting to increase access to ultrasound.

PURPOSE OF REVIEW: To summarize recent research findings and current concepts related to care of neurologic diseases in pregnancy and the risks of pregnancy to the mother-infant dyad. Recent publications related to best practices for neurologic care, risks of pregnancy, rate of relapse during and after pregnancy, as well as medication safety in pregnancy and lactation for more commonly used neurologic medications are reviewed. RECENT FINDINGS: Data continues to grow that women with neurologic conditions can experience pregnancy with minimal risks. Additionally, as more data is being published on medication safety in pregnancy and lactation, most medical therapy is now thought to be compatible, improving symptoms and care for women with neurologic conditions who require pharmacologic treatment. However, data remains limited from clinical trials and from more objective studies. Researchers continue to clarify the impact of pregnancy on the course of chronic neurologic diseases such as multiple sclerosis, myasthenia gravis, epilepsy, migraine, and cerebral aneurysms as well as the impact of these diseases on antepartum, labor and delivery, and postpartum management and neonatal course. Acute neurological conditions with pregnancy-associated risk such as stroke, posterior reversible encephalopathy syndrome, and cerebral venous sinus thrombosis are increasingly studied to determine individuals who are most vulnerable to these serious complications. SUMMARY: Many neurological diseases coexist with pregnancy. Recent research indicates a good prognosis for both mother and neonate. Although research related to neurologic disease in pregnancy is growing, it remains an area that deserves further focus to guide evidence-based care. With advances in research on therapeutic options, some women can achieve a safe pregnancy in the setting of chronic neurological disease. VIDEO ABSTRACT: http://links.lww.com/COOG/A45.

OBJECTIVE: To compare rates of antepartum contraceptive counseling among women with preterm birth (PTB) and term birth. STUDY DESIGN: This is a retrospective cohort study of patients with completed delivery records in New York from January 1, 2004, to December 31, 2014. Exposure was determined based on the timing of delivery. Exposed women delivered at <37 weeks, and nonexposed women delivered at ≥37 weeks. Primary outcome was patient response to questions regarding receipt of prenatal contraceptive counseling (PCC) by a health care provider. Secondary outcome was receipt of interpregnancy interval counseling. Chi-square tests and multivariate logistic regression were used for analysis. RESULTS: Of 724,723 delivery records, PTB rate was 7.9%. Women with PTB < 37 weeks were significantly less likely to receive PCC (odds ratio [OR]: 0.9; 95% confidence interval [CI]: 0.89-0.93) or interpregnancy interval counseling (OR: 0.95; 95% CI: 0.94-0.97). The primary outcome remained significant after adjusting for confounders (adjusted OR: 0.91; 95% CI: 0.89-0.93). PTB < 34 weeks was associated with even lower odds of receiving contraceptive counseling (OR: 0.79; 95% CI: 0.76-0.83). CONCLUSION: Postpartum contraception is an important tool for the prevention of recurrent PTB. Antepartum contraception counseling increases postpartum contraceptive uptake. Women with PTB have less exposure to antepartum contraceptive counseling. Lack of adequate counseling and decreased uptake of postpartum contraception may impact future pregnancy outcomes.

Perinatal Mental Health Disorders (PMHDs) pose significant challenges to the well-being of perinatal individuals, infants, and families. Despite their prevalence and impact, PMHDs often go undetected and untreated due to gaps in clinician education and training. This manuscript reviews the current state of perinatal mental health training, identifies emerging initiatives, and discusses innovative models of care aimed at enhancing the clinical preparedness of healthcare providers. Key findings highlight disparities in PMHD detection and treatment, the need for standardized education across disciplines, and the role of interdisciplinary collaboration in improving care outcomes. The manuscript emphasizes the urgency of prioritizing reproductive psychiatry education to mitigate the adverse effects of PMHDs on maternal and infant health. By standardizing education and fostering interdisciplinary collaboration, we can ensure that all perinatal individuals receive the care they need to thrive.

INTRODUCTION: Little is known about the care provided following positive depression screens in obstetrics and gynecology (Ob/Gyn) patients. METHOD: This study evaluated documented care plans and outcomes for 445 Ob/Gyn patients with positive depression screens between January 2018 and December 2020. Logistic regression models were estimated to identify predictors of changes in documented care plans and to test if a documented plan was associated with a reduction in depression severity in 6 months. RESULTS: The sample consisted of 445 patients who were on average 35.5 (SD = 12.8) years; 206 (46.3%) were White and 178 (40.0%) were Black. A total of 64 (14.4%) had a depression care plan documenting antidepressant initiation or change and/or psychotherapy referral. Relative to those aged 18-29, patients 40 or older had approximately 60% lower odds of a documented care plan change (OR = 0.394; p < .05). Relative to those seen by nurses, patients seen by physicians had approximately 70% lower odds of having treatment change (OR = 0.282; p < .05). Patients with a depression care plan documented had approximately 2.7 times higher odds of achieving 50% or more reduction in their Patient Health Questionnaire-9 depression severity score than those without a documented plan (OR = 2.685; p = .009). DISCUSSION: While most patients did not experience an initiation or change in their depression care plan on the same day as their positive screen, those patients with a plan documented showed significantly more improvement than those who did not. Standardized recommendations may improve depression outcomes among patients with positive depression screens. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
RESUMO
ABSTRACT: Obstetric volume sweep imaging (OB VSI) is a simple set of transducer movements guided by external body landmarks that can be taught to ultrasound-naive non-experts. This approach can increase access to ultrasound in rural/low-resources settings lacking trained sonographers. This study presents and evaluates a training program for OB VSI. Six trainees without previous formal ultrasound experience received a training program on the OB VSI protocol containing focused didactics and supervised live hands-on ultrasound scanning practice. Trainees then independently performed 194 OB VSI examinations on pregnancies >14 weeks with known prenatal ultrasound abnormalities. Images were reviewed by maternal-fetal medicine specialists for the primary outcome (protocol deviation rates) and secondary outcomes (examination quality and image quality). Protocol deviation was present in 25.8% of cases, but only 7.7% of these errors affected the diagnostic potential of the ultrasound. Error rate differences between trainees ranged from 8.6% to 53.8% ( P < 0.0001). Image quality was excellent or acceptable in 88.2%, and 96.4% had image quality capable of yielding a diagnostic interpretation. The frequency of protocol deviations decreased over time in the majority of trainees, demonstrating retention of training program over time. This brief OB VSI training program for ultrasound-naive non-experts yielded operators capable of producing high-quality images capable of diagnostic interpretation after 3 hours of training. This training program could be adapted for use by local community members in low-resource/rural settings to increase access to obstetric ultrasound.

Purpose of review: Obesity is a chronic disease that is becoming increasingly prevalent, and more individuals of reproductive age have obesity prior to becoming pregnant. Obesity in pregnancy is associated with short- and long-term adverse consequences for both the birthing person and their offspring which have been associated with increased long-term cardiovascular morbidity and mortality. The goal of this review is to discuss what is currently understood about the relationship between maternal obesity and adverse pregnancy outcomes (APOs), the association between APOs and future cardiovascular disease (CVD) risk, and what evidence-based interventions can be implemented to prevent adverse outcomes in this population. Recent findings: Maternal obesity has been associated with an increased risk of APOs such as gestational diabetes, hypertensive disorders of pregnancy, and preterm birth as well as an increased risk of future CVD, such as metabolic syndrome, chronic hypertension, coronary heart disease, and stroke. The impact of maternal obesity also extends beyond the pregnant individual to the offspring, increasing the risk of fetal, neonatal, and infant mortality, as well as of congenital malformations, prematurity, and long-term health problems such as insulin resistance and childhood obesity. Prevention guidelines are incorporating the increased risk of adverse outcomes from maternal obesity into formalized risk assessments to guide both prenatal and postpartum care. It is becoming evident that a multidisciplinary cardio-obstetrics team is an important part of providing comprehensive care for pregnant individuals with obesity and other cardiovascular risk factors, including preexisting CVD and a history of prior APOs. There remains a need for further studies to better understand the mechanisms underlying the relationship between maternal obesity and APOs, as well as the racial and ethnic disparities that have been noted in the prevalence of APOs and associated CVD risk and mortality. Summary: There is increasing awareness that obesity in pregnancy is associated with various short- and long-term adverse maternal and offspring outcomes. There are multiple screening and prevention strategies that may be implemented before, during, and after pregnancy to prevent these adverse outcomes.
RESUMO
OBJECTIVE: To estimate the diagnostic accuracy of blind ultrasound sweeps performed with a low-cost, portable ultrasound system by individuals with no prior formal ultrasound training to diagnose common pregnancy complications. METHODS: This is a single-center, prospective cohort study conducted from October 2020 to January 2022 among people with second- and third-trimester pregnancies. Nonspecialists with no prior formal ultrasound training underwent a brief training on a simple eight-step approach to performing a limited obstetric ultrasound examination that uses blind sweeps of a portable ultrasound probe based on external body landmarks. The sweeps were interpreted by five blinded maternal-fetal medicine subspecialists. Sensitivity, specificity, and positive and negative predictive values for blinded ultrasound sweep identification of pregnancy complications (fetal malpresentation, multiple gestations, placenta previa, and abnormal amniotic fluid volume) were compared with a reference standard ultrasonogram as the primary analysis. Kappa for agreement was also assessed. RESULTS: Trainees performed 194 blinded ultrasound examinations on 168 unique pregnant people (248 fetuses) at a mean of 28±5.85 weeks of gestation for a total of 1,552 blinded sweep cine clips. There were 49 ultrasonograms with normal results (control group) and 145 ultrasonograms with abnormal results with known pregnancy complications. In this cohort, the sensitivity for detecting a prespecified pregnancy complication was 91.7% (95% CI 87.2-96.2%) overall, with the highest detection rate for multiple gestations (100%, 95% CI 100-100%) and noncephalic presentation (91.8%, 95% CI 86.4-97.3%). There was high negative predictive value for placenta previa (96.1%, 95% CI 93.5-98.8%) and abnormal amniotic fluid volume (89.5%, 95% CI 85.3-93.6%). There was also substantial to perfect mean agreement for these same outcomes (range 87-99.6% agreement, Cohen κ range 0.59-0.91, P<.001 for all). CONCLUSION: Blind ultrasound sweeps of the gravid abdomen guided by an eight-step protocol using only external anatomic landmarks and performed by previously untrained operators with a low-cost, portable, battery-powered device had excellent sensitivity and specificity for high-risk pregnancy complications such as malpresentation, placenta previa, multiple gestations, and abnormal amniotic fluid volume, similar to results of a diagnostic ultrasound examination using a trained ultrasonographer and standard-of-care ultrasound machine. This approach has the potential to improve access to obstetric ultrasonography globally.

Ultrasound imaging is a vital component of high-quality Obstetric care. In rural and under-resourced communities, the scarcity of ultrasound imaging results in a considerable gap in the healthcare of pregnant mothers. To increase access to ultrasound in these communities, we developed a new automated diagnostic framework operated without an experienced sonographer or interpreting provider for assessment of fetal biometric measurements, fetal presentation, and placental position. This approach involves the use of a standardized volume sweep imaging (VSI) protocol based solely on external body landmarks to obtain imaging without an experienced sonographer and application of a deep learning algorithm (U-Net) for diagnostic assessment without a radiologist. Obstetric VSI ultrasound examinations were performed in Peru by an ultrasound operator with no previous ultrasound experience who underwent 8 hours of training on a standard protocol. The U-Net was trained to automatically segment the fetal head and placental location from the VSI ultrasound acquisitions to subsequently evaluate fetal biometry, fetal presentation, and placental position. In comparison to diagnostic interpretation of VSI acquisitions by a specialist, the U-Net model showed 100% agreement for fetal presentation (Cohen's κ 1 (p<0.0001)) and 76.7% agreement for placental location (Cohen's κ 0.59 (p<0.0001)). This corresponded to 100% sensitivity and specificity for fetal presentation and 87.5% sensitivity and 85.7% specificity for anterior placental location. The method also achieved a low relative error of 5.6% for biparietal diameter and 7.9% for head circumference. Biometry measurements corresponded to estimated gestational age within 2 weeks of those assigned by standard of care examination with up to 89% accuracy. This system could be deployed in rural and underserved areas to provide vital information about a pregnancy without a trained sonographer or interpreting provider. The resulting increased access to ultrasound imaging and diagnosis could improve disparities in healthcare delivery in under-resourced areas.

OBJECTIVE: To systematically review the prevalence of antenatal depression and anxiety in women hospitalized in an antepartum unit for obstetric complications. DATA SOURCES: We searched PubMed, EMBASE, CINAHL, PsycINFO, and ClinicalTrials.gov for English-language articles published from database inception through March 2020. METHODS OF STUDY SELECTION: We included cross-sectional, cohort, case-control, quasi-experimental, and randomized controlled studies from any country that reported the proportion of pregnant women with an elevated depression or anxiety screening scale or diagnostic interview during antepartum hospitalization of any duration and at any gestational age. TABULATION, INTEGRATION, AND RESULTS: We identified 8,799 articles and reviewed 79, 39 of which were included in a systematic review and 18 in meta-analysis of the primary outcome. Two raters independently assessed quality of individual studies using a 14-question tool. A random effects meta-analysis model was used to estimate prevalence and 95% CI of depression or anxiety. Heterogeneity was examined with the I2 test, and funnel plots were used to assess publication bias. After meta-analysis, the estimated prevalence of depression was 34% (95% CI 27-41%) and of anxiety 29% (95% CI 16-43%). There was expected substantial clinical and methodologic heterogeneity between studies that persisted even after planned a priori subgroup analyses and meta-regression. Even so, the direction of effect was consistent across studies. No publication bias was found. CONCLUSION: The current meta-analysis suggests that one in three women hospitalized during pregnancy for obstetric complications report clinical levels of depression or anxiety symptoms, twice the reported prevalence of antenatal depression or anxiety in the general obstetric population.

Objective: Obesity increases the difficulty of completing the fetal anatomic survey. This is of added concern in obese gravidas who are at higher risk of congenital fetal anomalies. We hypothesized that incorporation of an early transvaginal assessment could improve the completion rate of the fetal anatomic survey in obese women.Methods: We performed a prospective, longitudinal, blinded study of obese gravidas (BMI ≥ 35 kg/m2) comparing the use of a single early second trimester transvaginal ultrasound in addition to midtrimester transabdominal ultrasound versus traditional serial midtrimester ultrasound alone for completion of the anatomic survey. Transvaginal ultrasound for anatomy was performed between 13 0/7 and 15 6/7 week followed by midtrimester anatomic ultrasound, with each patient serving as her own control. Structures were marked as optimally or suboptimally viewed after each ultrasound. Sonographers and reviewers were blinded to images from the transvaginal ultrasound. Completion rates and gestational age at completion were compared between groups.Results: Fifty subjects were included. Fetal anatomic survey was completed in 62% using standard midtrimester assessment versus 78% with the addition of early transvaginal assessment (p = .04). The survey was completed at an earlier gestational age utilizing the transvaginal approach (22 0/7 ± 6 3/7) compared to traditional midtrimester transabdominal ultrasound approach (25 2/7 ± 5 3/7) p < .0005.Conclusions: Incorporation of an early transvaginal assessment of anatomy in obese women improved the rate of completion and led to earlier gestational age at completion of the fetal anatomic survey. Consideration should be given to including an early transvaginal sonogram as part of routine assessment of women with a BMI ≥ 35.

Mental health disorders are common and have a significantly negative impact on the health and well-being of women. For example, perinatal mental health disorders such as anxiety and depression are widely understood to be the most common complications of pregnancy and childbirth. Untreated mental health disorders are associated with significant obstetrical and psychiatric sequelae and have a long-lasting impact on neonatal and childhood outcomes. As front-line providers for women during times of elevated risk of psychiatric morbidity, such as pregnancy and postpartum, obstetricians and gynecologists are compelled to have familiarity with such disorders. Yet, a wide gap exists between the level of education in mental health disorders that obstetrician and gynecologist providers receive and the clinical need thereof. The objectives of this commentary are to describe the urgent need for mental health education for obstetricians and gynecologists providers and to introduce our vision for a concise, evidence-based and accessible set of digital educational materials designed to convey core concepts in women's reproductive mental health.
