Abstract

Background – There is a paucity of data describing the effects of COVID-19, especially in asymptomatic patients, on placental pathology. Although the pathophysiology of COVID-19 is not completely understood, there is emerging evidence that it causes a severe systemic inflammatory response and results in a hypercoagulable state with widespread microthrombi. We hypothesized that it is plausible that a similar disease process may occur in the fetal-maternal unit. Objective – The aim of this study was to determine whether COVID-19 in term patients admitted to Labor and Delivery, including women without COVID-19 symptomatology, is associated with increased placental injury compared to a cohort of COVID-19 negative controls. Study Design – This was a retrospective cohort study performed at NYU Winthrop Hospital between 3/31/2020 and 6/17/2020. During the study period all women admitted to Labor and Delivery were routinely tested for SARS-CoV-2 regardless of symptomatology. The placental histopathological findings of COVID-19 patients (n=77) who delivered a singleton gestation at term were compared to a control group of term patients without COVID-19 (n=56). Controls were excluded if they had obstetric or medical complications including fetal growth restriction, oligohydramnios, hypertension, diabetes, coagulopathy or thrombophilia. Multivariable logistic regression models were performed for variables that were significant in univariable analyses. A subgroup analysis was also performed comparing asymptomatic COVID-19 cases to negative controls. Results – In univariable analyses, COVID-19 cases were more likely to have evidence of fetal vascular malperfusion, i.e. presence of avascular villi and/or mural fibrin deposition (32.5% (25/77) vs. 3.6% (2/56), p

Abstract

The purpose of the study was to validate prospectively a previous retrospectively established nomogram for the prediction of gestational age using transcerebellar diameter, especially in the third trimester. This prospective study demonstrates that transcerebellar diameter measurement is an accurate predictor of gestational age, even in the third trimester of pregnancy.

Abstract

Objectives: To determine the feasibility in visualizing placental cord insertion (PCI) during second-trimester fetal anatomical survey and the association between marginal cord insertion (MCI) and preterm delivery (PTD) and low birth weight (LBW). Our secondary objectives were to evaluate the association of MCI with adverse composite obstetrical and neonatal outcomes. Methods: A prospective cohort study was performed over a 28-month period. Women with singleton pregnancies presenting for routine anatomical survey between 18 and 22 weeks' gestation were included. PCI site was visualized on 2D grayscale and color Doppler and the shortest distance from the sagittal and transverse planes to the placental edge were recorded. MCI was diagnosed when any of measured distances was ≤2 cm. Correlations were assessed via bivariate chi-squared, independent t-test analyses and Fisher's exact tests. Regression models evaluated associations between MCI and adverse composite outcomes. Results: Three hundred one women were included and PCI was feasible in all cases. The incidence of MCI was 11.3% (n = 34). Baseline characteristics between those with and without MCI were similar, except for story of prior PTD, which was greater among those with MCI (17.65 versus 7.17%, p = .04). MCI was associated with increased likelihood of LBW (RR four; 95%CI, 1.46-10.99) and PTD (RR 3.2; 95%CI, 1.53-6.68); in multivariate analysis, we found associations between MCI and composite adverse obstetrical (RR 2.33; 95%CI, 1.30-4.19) and neonatal (RR 2.46; 95%CI, 1.26-4.81) outcomes. Conclusions: Evaluation of PCI is feasible in all cases. Second-trimester MCI is associated with increased likelihood for LBW, PTD, and composite adverse obstetrical and neonatal outcomes.

Abstract

Objective: The prenatal detection rate of isolated fetal limb abnormalities ranges from 4 to 29.5%. Our aim was to determine the accuracy of a detailed ultrasound protocol in detecting isolated fetal limb abnormalities Methods: This is a retrospective study of infants born at our institution with isolated limb defects from 2009 to 2014. Antepartum and postpartum records were reviewed for genetic testing results. We routinely image both upper and lower extremities, including all long bones, hands, feet, fingers and toes. Posturing, muscular tone and movement are also noted.Results: During the study period, there were 52 neonates born with isolated fetal limb abnormalities who had received a fetal anatomic survey in our ultrasound unit and 15 930 sonograms performed with normal findings; 36 out of the 52 had been prenatally diagnosed (detection rate 69%). The specificity of the protocol was 100% as there were no false positive cases, the positive predictive value was 100% and negative predictive value 99.8%. Forty-three of 52 neonates had normal genetic testing either prenatally or postnatally; 9 neonates did not undergo genetic testing. The average additional time required for this detailed protocol was <5 min for second trimester sonogram.Conclusion: A minimal investment in time for detailed evaluation of fetal limbs more than doubles the previously reported prenatal detection rate.

Abstract

Martin Chavez was born in October 22, 1942 in Compton, California. He grew up in the Watts community. His mother was a homemaker and his father was a crane operator and was a union member. In 1964, after serving in the Air Force, he went to work for McDonnell Douglas and joined the UAW. After being transferred to Santa Monica following a layoff, he joined the IAM and became a shop steward. During that time, he was involved in a 62 day strike. He transferred to Huntington Beach where he was also a shop steward. He then went to Western Airlines as a mechanic. After Western was bought out by Delta he was hired by United Airlines, where he served as a trustee for local lodge 1932. He retired in 2003. He remains active with the union and is working to document the history of the local., Chavez begins the interview discussing his family background. His mother was a homemaker and his was a crane operator and a member of steelworkers union. He goes to work for McDonnell Douglas after serving in the Air Force and joins UAW. After a layoff, he is transferred to Santa Monica, and became shop steward for the IAM. He recalls being involved in the 62 day strike and eventually is transferred to Huntington Beach, where he also served as shop steward. Chavez talks about working at Western Airlines, and then being hired by United Airlines, where he served as a trustee. He recalls about working with Steve Cook and the negotiations they had with company. Chavez discusses retiring for medical reasons in 2003.

Abstract

Objective: To determine if a structured teaching module improves resident competency in transvaginal sonographic cervical length measurements. Methods: This was a prospective cohort study involving obstetrics and gynecology residents at a single institution. Residents collected 10 transvaginal cervical images from patients with threatened preterm labor presenting to Labor and Delivery. After initial image acquisition, residents participated in a lecture-based teaching module involving a pre- and post-intervention assessment. Following the didactic session, they collected 10 additional images. All the images were scored independently by two Maternal-Fetal Medicine attending physicians based on the quality and accuracy of the measured cervical length. Pre-and post- intervention test results were compared, as well as pre- and post- intervention image scores. Parametric and nonparametric tests were used as appropriate with p < 0.05 considered significant. Results: Ninety-three percent of the residents (14/15) improved their scores from pre-test to post-test or maintained an already perfect score (p < 0.01). Improvement was most significant with the junior residents. Seventy-nine percent of the residents (11/14) improved their cervical image scores after the educational session. Mean score for total residents was 73.7 + 12.6 pre-intervention and 90.2 + 9.9 post-intervention (p < 0.01) out of a total of 120. Conclusions: There is an improvement in the competence of resident measured cervical lengths via transvaginal ultrasound when a structured educational module is implemented for resident education.
