RESUMEN
BACKGROUND: Gastroschisis is often complicated by fetal growth restriction, preterm delivery, and prolonged neonatal hospitalization. Prenatal management and delivery decisions are often based on estimated fetal weight and interval growth; however, appropriate interval growth from week to week across gestation for these fetuses is poorly understood. OBJECTIVE: This study aimed to determine the median increase in overall estimated fetal weight and individual biometric measurements across each week of gestation in pregnancies with fetal gastroschisis and to assess whether lower in utero fetal weight gain is predictive of postnatal growth or adverse neonatal outcomes. STUDY DESIGN: This was a retrospective cohort study of pregnancies with gastroschisis evaluated at 5 institutions of the University of California Fetal-Maternal Consortium from December 2014 to December 2019. The inclusion criteria were prenatally diagnosed gastroschisis with at least 1 ultrasound performed at a University of California Fetal-Maternal Consortium institution. Estimated fetal weight and individual biometric measurements were recorded for each ultrasound performed at a University of California Fetal-Maternal Consortium institution from the time of gastroschisis diagnosis to delivery. Median estimated fetal weight and biometric measurements were calculated for each gestational age in 1-week increments. Neonatal outcomes collected were birthweight, length of stay, complications of gastroschisis (bowel atresia, bowel stricture, ischemic bowel before closure, or severe pulmonary hypoplasia), and growth failure at discharge. RESULTS: We identified 95 pregnancies with fetal gastroschisis who, in aggregate, had 360 growth ultrasounds at a University of California Fetal-Maternal Consortium institution. The median interval growth was 130 g/wk. The median estimated fetal weight and abdominal circumference in fetal gastroschisis cases were approximately the tenth percentile on the Hadlock growth curve across gestation. Moreover, the median biparietal diameter, head circumference, and femur length measurements remained below the 50th percentile on the Hadlock growth curve across gestation. The median birthweight for neonates with less than the median weekly prenatal weight gain was less than for those with greater than the median weekly prenatal weight gain (2185 g vs 2780 g; P<.01). There was no difference in prenatal weight gain trajectory when comparing neonates who had or did not have bowel complications of gastroschisis. CONCLUSION: In this multicenter cohort of pregnancies with fetal gastroschisis, the median interval growth was 130 g/wk, and overall, in utero growth closely followed the tenth percentile on the Hadlock curve. Poor prenatal growth in cases of fetal gastroschisis correlates with lower neonatal weights but did not predict a more complicated course.

PURPOSE: Chromosomal microarray (CMA) is recommended in the diagnostic evaluation of cases with fetal structural anomalies when invasive testing is pursued. However, the utility of CMA for nonimmune hydrops fetalis (NIHF) specifically is not well known. Our objective was to describe the overall yield of CMA in the diagnostic evaluation of NIHF, comparing isolated cases to those with concurrent structural anomalies. METHODS: This was a retrospective cohort study of all prenatally diagnosed NIHF cases evaluated at the University of California, San Francisco from 2008 to 2018. NIHF due to twin-twin transfusion syndrome was excluded. RESULTS: There were 131 cases of prenatally diagnosed NIHF. In 43/44 cases with a CMA performed, results were categorized as normal or likely benign. One case was found on CMA to have a large pathogenic duplication of 21p11.2q22.3, which could have been detected by karyotype and was consistent with a diagnosis of Down syndrome. There was no incremental yield demonstrated for CMA over karyotype. CONCLUSIONS: Among a cohort of prenatally diagnosed NIHF cases, CMA did not identify any copy number variants beyond those detectable by karyotype, and the vast majority of CMAs were normal. These results suggest that CMA has low diagnostic utility for NIHF.

Women physicians have a long history of advocacy, dating to the 19th century women's suffrage movement. As history recounts the work of the suffragists, many women physicians bear mention. Some were leaders on the national scene, and others led suffrage efforts in their own state. In this article, we provide a snapshot of 7 prominent suffragists who were also physicians: Mary Edwards Walker, Mary Putnam Jacobi, Esther Pohl Lovejoy, Marie Equi, Mattie E. Coleman, Cora Smith Eaton, and Caroline E. Spencer. In sharing their stories, we hope to better understand some of the challenges and struggles of the suffrage movement and how their advocacy paved the way not only for women's voting rights but also the role of women physicians as advocates for change.

PURPOSE: Numerous etiologies may lead to nonimmune hydrops fetalis (NIHF), and the underlying cause often remains unclear. We aimed to determine the proportion of NIHF cases in which the etiology was clearly determined in a large, contemporary, and diverse cohort, as well as to describe the etiologies with a focus on genetic causes. METHODS: Retrospective review of NIHF cases between 2015 and 2017 from the five University of California Fetal-Maternal Consortium sites. Singleton pregnancies with prenatally diagnosed NIHF were included, and cases with maternal alloimmunization were excluded. Cases were categorized as being of confirmed, suspected, or unknown etiology. RESULTS: Sixty-five NIHF cases were identified. Forty-six percent (30/65) remained of unknown etiology, while 9.2% (6/65) had a suspected etiology and 44.6% (29/65) were of confirmed etiology. Among confirmed cases, 11 resulted from aneuploidy; 7 from fetal structural anomalies; 2 each from fetal arrhythmia, Noonan syndrome, and generalized lymphatic dysplasia; and 1 each from arthrogryposis, parvovirus, neonatal alloimmune thrombocytopenia, fetal goiter, and Kasabach-Merritt syndrome. CONCLUSION: In this contemporary, multicenter study, the cause of prenatally diagnosed NIHF was confirmed in only 44% of cases, and a genetic etiology was found in only 25% of those that received standard of care genetic testing.
