Abstract
PURPOSE This study aimed to investigate the correlation between chromosomal abnormalities in spontaneous abortion with clinical features and seek copy number variations (CNVs) and genes that might be connected to spontaneous abortion. METHODS Over 7 years, we used CNV-seq and STR analysis to study POCs, comparing chromosomal abnormalities with clinical features and identifying critical CNVs and genes associated with spontaneous abortion. RESULTS Total chromosomal variants in the POCs were identified in 66.8% (2169/3247) of all cases, which included 45.2% (1467/3247) numerical abnormalities and 21.6% (702/3247) copy number variants (CNVs). Chromosome number abnormalities, especially aneuploidy abnormalities, were more pronounced in the group of mothers aged ≥ 35 years, the early miscarriage group, and the chorionic villi group. We further analyzed 212 pathogenic and likely pathogenic CNVs in 146 POCs as well as identified 8 statistically significant SORs through comparison with both a healthy population and a group of non-spontaneously aborted fetuses. Our analysis suggests that these CNVs may play a crucial role in spontaneous abortion. Furthermore, by utilizing the RVIS score and MGI database, we identified 86 genes associated with spontaneous abortion, with particular emphasis on PARP6, ISLR, ULK3, FGFRL1, TBC1D14, SCRIB, and PLEC. CONCLUSION We found variability in chromosomal abnormalities across clinical features, identifying eight crucial copy number variations (CNVs) and multiple key genes that may be linked to spontaneous abortion. This research enhances the comprehension of genetic factors contributing to spontaneous abortion.

Abstract
El objetivo del trabajo es analizar dos conductas médicas opuestas en la vida prenatal de los niños con trisomía 18: el aborto y los cuidados paliativos perinatales. Se realizó una búsqueda bibliográfica en PubMed a partir de los términos “trisomy 18”, “abortion” y “palliative care”. Actualmente, están cambiando las conductas médicas dirigidas a los niños nacidos con trisomía 18, debido a que ya no se la considera una enfermedad incompatible con la vida. Este cambio de paradigma en la conducta médica posnatal debería reflejarse en la conducta prenatal, para ofrecer a los padres alternativas distintas al aborto. Los cuidados paliativos fetales y perinatales constituyen una respuesta ética válida para el tratamiento de niños con trisomía 18.

Abstract
OBJECTIVES To identify factors associated with prenatal, perinatal, and postnatal outcomes, and determine medical care use for fetuses and infants with trisomy 13 (T13) and trisomy 18 (T18). STUDY DESIGN This population-based retrospective cohort study included all prenatal and postnatal diagnoses of T13 or T18 in the greater Cincinnati area from January 1, 2012, to December 31, 2018. Overall survival, survival to hospital discharge, medical management, and maternal, fetal, and neonatal characteristics are analyzed. RESULTS There were 124 pregnancies (125 fetuses) that were identified, which resulted in 72 liveborn infants. Male fetal sex and hydrops were associated with a higher rate of spontaneous loss. The median length of survival was 7 and 29 days, for infants with T13 and T18, respectively. Of the 27 infants alive at 1 month of age, 13 (48%) were alive at 1 year of age. Only trisomy type (T13), goals of care (comfort care), and extremely low birthweight were associated with a shorter length of survival. A high degree of variability existed in the use of medical services, with 28% of infants undergoing at least 1 surgical procedure and some children requiring repeated (≤29) or prolonged (>1 year) hospitalizations. CONCLUSIONS Although many infants with T13 or T18 did not survive past the first week of life, nearly 20% lived for more than 1 year with varying degrees of medical support. The length of survival for an infant cannot be easily predicted, and surviving infants have high health care use throughout their lifespans.

Abstract
OBJECTIVE This study aimed to examine maternal outcomes of ongoing pregnancies complicated by fetal life-limiting conditions. STUDY DESIGN This was a retrospective matched cohort study of women with a diagnosis of fetal life-limiting condition between 2010 and 2018 in a single academic center. Cases were matched to controls (women who had normal fetal anatomic survey) according to year of delivery, body mass index, and parity in a 1:4 ratio. Bivariable and multivariable analyses were performed to compare the prevalence of the primary composite outcome, which included any one of the following: preeclampsia, gestational diabetes, cesarean delivery, third and fourth degree laceration, postpartum hemorrhage, blood transfusion, endometritis or wound infection, maternal intensive care unit admission, hysterectomy and maternal death, between cases and controls. RESULTS During the study period, we found 101 cases that met inclusion criteria, matched to 404 controls. The rate of the composite maternal outcome did not differ between the two groups (39.6 vs. 38.9%, p = 0.948). For individual outcomes, women with diagnosis of fetal life-limiting condition had higher rates of blood transfusion (2.0 vs. 0%, p = 0.005) and longer length of the first stage of labor (median of 12 [6.8-22.0] hours vs. 6.6 [3.9-11.0] hours; p < 0.001). In a multivariable analysis, first stage of labor continued to be longer by an average of 6.48 hours among women with a diagnosis of fetal life-limiting condition compared with controls. CONCLUSION After controlling for confounding factors, except a longer first stage of labor, women diagnosed with fetal life-limiting conditions who continued the pregnancy did not have a higher rate of adverse maternal outcomes. KEY POINTS · The rates of ongoing pregnancies with fetal life-limiting conditions are increasing.. · Women with ongoing pregnancies with fetal life-limiting conditions had longer first stage of labor.. · The rest of the adverse maternal outcomes were not increased in this obstetric population..

Abstract
PURPOSE Describe practice patterns among obstetrician/gynecologists (OB/GYNs) when caring for women with pregnancy complicated by fetal trisomy 13 (T13) or 18 (T18) and compare these between maternal-fetal medicine (MFM) and non-MFM providers. MATERIALS AND METHODS We conducted an electronic survey using the American College of Obstetricians and Gynecologists database. Using simple statistics, we describe demographics and practice patterns among respondents and compare those of MFM practitioners with non-MFM providers. RESULTS The survey was sent to 300 individuals, 161 individuals verified email receipt, and 105 had complete response and were included. The median age was 58 (IQR 53,62). Sixty percent were female, 69% were private practice, and 38% were MFM. All providers were more likely to offer than to recommend antenatal and intrapartum interventions. MFMs were more likely to offer growth ultrasounds and neonatal hospice consults (53% vs. 29%, p = .02; 88% vs. 60%, p < .01). During labor, MFMs were more likely offer no fetal heart rate monitoring, (90% vs. 52%, p < .01), 60% of all providers offer breech vaginal delivery; 32% offer cesarean delivery for fetal distress. CONCLUSION Many providers offer antepartum and intrapartum interventions for pregnancies complicated by T13/18. We recommend that providers elicit each woman's goals for pregnancies complicated by T13/18 and tailor management options to meet these goals.
