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 pregnancies14 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% (P0.0001). 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.

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.

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

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 κ =0.74 (p 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.

OBJECTIVE: To systematically review the prevalence of antenatal depression and anxiety in women hospitalized on an antepartum unit for obstetric complications. DATA SOURCES: We searched Pubmed, Embase, Cumulative Index to Nursing and Allied Health Literature (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, thirty-nine 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% confidence interval of depression or anxiety. Heterogeneity was examined with the I(2) 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 which 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: 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 ∼1:2 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 Hemophagocytic lymphohistiocytosis (HLH) is a rare and life-threatening disease. It is characterized by impaired natural killer cell and cytotoxic lymphocyte function leading to dysregulated macrophage phagocytosis of erythrocytes, leukocytes and platelets. Coupled with a massive release of cytokines this rapidly leads to multi-organ failure and mortality if not treated promptly. Case presentation We report a case of pregnancy-associated, treatment-resistant HLH with no identified risk factors. Conclusion It is likely that HLH is an unrecognized cause of intractable fever and disseminated intravascular coagulation (DIC) in young pregnant women and it should be included in the differential diagnosis when patients do not respond to typical therapies. High serum ferritin should further prompt consideration of this diagnosis. This rare disease is often not thought of and many gynecologist obstetricians have never heard of it, making this case report of essential importance to reignite the interest in HLH, particularly when it occurs during pregnancy.

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.

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.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.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 Results Of 724,723 delivery records, PTB rate was 7.9%. Women with PTB 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.
