Abstract	Placenta accreta spectrum (PAS) defined by various degrees of abnormally invasive placentation is strongly associated with severe maternal morbidity and maternal mortality, mainly reflecting maternal hemorrhage. Predisposing factors for this condition include: multiparity, placenta previa, previous uterine surgeries (previous curettage, cesarean delivery, and myomectomy), smoking and previous PAS. Prenatal sonographic findings associated with PAS include the presence of placenta previa, loss of the hypoechoic retroplacental sonolucency, myometrial thinning, interruption of the irregularity of the bladder wall, excessive vascularity of the uterovesical plane, placental lacunae, increased placental vascularity, bridging vessels with vascularity extending from the placental bed across the uterine wall into the bladder or other pelvic organs. PAS is very rare among nulliparous patients, especially those without previous uterine surgery. We describe an unusual case of PAS in a nulliparous patient with an unscarred uterus and systemic lupus erythematosus in whom a fundal placenta with PAS and thinned and areas of absent myometrium suspected at midtrimester sonography, sustained uterine atony and severe hemorrhage at delivery, necessitated massive blood transfusion and subtotal hysterectomy. Both mother and infant did well. Pathology confirmed PAS and marked uterine thinning. Although PAS most commonly is associated with placenta previa and the presence of previous cesarean delivery, this case emphasizes the need for alertness of at times subtle prenatal sonographic findings of PAS irrespective of placental location even among nulliparous patients, especially those with systemic lupus erythematosus.

Abstract	Ectopic pregnancies, implantation of a fertilized ovum in any location other than within the endometrial cavity, occur in 1-2% of all pregnancies. Despite current enhanced early diagnosis enabled by serum beta-human choriogonadotropin (hCG) levels and high-resolution ultrasound, this clinical entity continues to account for between 2.7 and 6% of all maternal deaths. The most common site of ectopic implantation is the Fallopian tube (>90% of cases), and less commonly in previous Cesarean scar, ovary, cervix, or the abdomen. Complete tubal abortion refers to a tubal pregnancy having been expelled from the distal portion of the Fallopian tube into the peritoneal cavity and may be associated with either considerable hemorrhage, spontaneous resolution, or rarely serve as an initial nidus for an abdominal pregnancy. We present unusual sonographic findings of a complete tubal abortion in a patient with minimal symptomology.

Abstract	Etiologies underlying the relatively infrequent third-trimester sonographic depiction of dilated fetal bowel include (functional or mechanical) bowel obstruction, intestinal atresia, volvulus, annular pancreas, intestinal malrotation, intussusception, gastrointestinal duplications, cystic fibrosis-associated meconium ileus, congenital chloride diarrhea, microvillus inclusion disease, intestinal neuronal dysplasia, and meconium plug syndrome. Fetal bowel obstruction may be associated with aneuploidy (mostly Trisomy 21 in association with esophageal or duodenal atresia), and rarely select microduplications or deletions. We present unusual sonographic findings associated with transient marked proximal fetal bowel dilatation in association with concurrent development of oligohydramnios, in a growth-restricted fetus at 35 weeks' gestation. This case supports that upon observation of dilated loops of fetal bowel, while not negating the potential need for delivery secondary to potential bowel compromise, consideration should be given for observation in anticipation of potential spontaneous resolution of this condition, especially among growth-restricted fetuses with decreased amniotic fluid volume in prematurity.

Abstract	Lutein and its isomer zeaxanthin serve as antioxidants and preserve cognitive function during aging. However, whether lutein/zeaxanthin (L + Z) exposure early in life improves cognitive development of children is rarely explored. It is also unknown whether gestational diabetes mellitus (GDM), characterized by heightened oxidative stress, affects lutein metabolism. This prospective longitudinal cohort study examined the differences in L + Z intake and metabolism, as well as the association between maternal L + Z intake and children's cognitive development in GDM versus non-GDM pregnancies. Seventy-six pregnant women (

Abstract	Diagnosis of potential umbilical cord compromise, namely, true knots of the umbilical cord and nuchal cords has been enabled with increasing accuracy with current enhanced prenatal sonography. Often an incidental finding at delivery, the incidence of true knots of the umbilical cord has been estimated at between 0.04% and 3% of deliveries. This condition has been reported to account for a 4 to 10-fold increase of stillbirth and perinatal morbidity of 11% of cases. Nuchal cords, commonly observed at the delivery of uncompromised, non-hypoxic non-acidotic newborns occur more frequently with single nuchal cords noted in between 20% and 35% of all deliveries at term. Multiple nuchal cords are considerably less frequent, with decreasing frequencies inverse to the number of nuchal cord loops. While clearly single (and likely double) nuchal cords are almost uniformly associated with favorable neonatal outcomes, emerging data suggest that cases of ≥3 loops of nuchal cords are more likely to be associated with an increased risk of adverse perinatal outcome (either stillbirth or compromised neonatal condition at delivery). We define cases of a true knot of the umbilical cord, cases of ≥3 loops of nuchal cords, any combination of a true knot and nuchal cord, or any umbilical cord entanglement (nuchal or true knot) in the presence of a single umbilical artery, in singleton gestations as complex umbilical cord entanglement. Two concurrent developments, the increase in accuracy of prenatal sonographic diagnosis of complex umbilical cord entanglement and recent data confirming fatal compromise of the umbilical circulation in approximately 20% of cases of stillbirth, suggest that establishing governing body guidelines for reporting of potential umbilical cord compromise, and recommendation of consideration for early-term delivery of select cases, may be warranted. This commentary will address current perspectives of prenatal diagnosis and clinical management challenges of complex umbilical cord entanglement.

Abstract	The umbilical cord constitutes a continuation of the fetal cardiovascular system anatomically bridging between the placenta and the fetus. This structure, critical in human development, enables mobility of the developing fetus within the gestational sac in contrast to the placenta, which is anchored to the uterine wall. The umbilical cord is protected by unique, robust anatomical features, which include: length of the umbilical cord, Wharton's jelly, two umbilical arteries, coiling, and suspension in amniotic fluid. These features all contribute to protect and buffer this essential structure from potential detrimental twisting, shearing, torsion, and compression forces throughout gestation, and specifically during labor and delivery. The arterial components of the umbilical cord are further protected by the presence of Hyrtl's anastomosis between the two respective umbilical arteries. Abnormalities of the umbilical cord are uncommon yet include excessively long or short cords, hyper or hypocoiling, cysts, single umbilical artery, supernumerary vessels, rarely an absent umbilical cord, stricture, furcate and velamentous insertions (including vasa previa), umbilical vein and arterial thrombosis, umbilical artery aneurysm, hematomas, and tumors (including hemangioma angiomyxoma and teratoma). This commentary will address current perspectives of prenatal sonography of the umbilical cord, including structural anomalies and the potential impact of future imaging technologies.

Abstract	Prenatal sonographic depiction of congenital vertical talus (rocker bottom feet), describing a prominent calcaneus and rounded convex appearance of the ventral aspect of the foot, has been reported with fetal Trisomies 18, 13, 9 HOXD10 mutations and recently 2q13 microdeletion. We present a 24 year old in whom mid-trimester sonographic finding of isolated bilateral rocker bottom feet led to diagnosis of 7q11.23 microdeletion-Williams syndrome. This association has not been reported previously. This case emphasizes the critical assessment of detail microarray upon prenatal sonographic notation of abnormal structural fetal features.

Abstract	COVID-19 is a novel coronavirus with data suggesting a more serious clinical course in pregnancy. We aimed to assess changes in knowledge, behaviors, and intentions of pregnant women regarding COVID-19. This was a cross-sectional survey study of 58 and 77 predominantly African-American and Afro-Caribbean pregnant patients presenting for prenatal care in Brooklyn, NY in 2020 (during the first surge of the pandemic) and 2021, respectively. Descriptive and inferential statistics were performed. Many beliefs and intentions were unchanged between 2020 and 2021 (e.g. believing pregnant women were at higher risk of COVID-19 infection and subsequent ICU admission due to pregnancy, having the desire to breastfeed, among others). Other beliefs and behaviors changed between 2020 and 2021 (fewer women believed they received information from their provider regarding COVID-19 and fewer would miss a prenatal visit for fear of COVID-19 contagion). Patients' behaviors and intended behaviors in both 2020 and 2021 were directly influenced by their beliefs, many of which were based on unsupported data regarding COVID-19 and pregnancy (ie: babies were at increased risk of being born with congenital malformation following a mother's COVID-19 infection). Patients who held these beliefs were more likely to say that they did not attend prenatal visits and did not receive information from their provider regarding COVID-19. Knowledge of patient beliefs is useful for structuring care as the pandemic evolves. This study demonstrates that pregnant patients make decisions regarding behaviors based on beliefs grounded in misinformation. Accordingly, it is the provider's responsibility to ensure that beliefs regarding COVID-19 are based in fact, so patients can make informed decisions.

Abstract	Small bowel atresia constitutes congenital obstruction of the lumen of the duodenum, jejunum or ileum, and is one of the most common causes of neonatal bowel obstruction with a reported incidence of between 1.3 and 2.8 per 10,1000 live births. Complete absence of the small bowel, or near total jejuno-ileal atresia (in the absence of malrotation or gastroschisis), are extremely rare. Mid-trimester prenatal sonographic finding of dilated fetal bowel led to the finding of interstitial 8q21.13q21.2 duplication. Following delivery at 32 weeks' gestation, at laparotomy almost complete small bowel atresia was noted. Anastomosis between the existing small bowel and colon was performed. At 7 months of age, the infant continued to receive total parenteral nutrition supplemented by gastrostomy and oral-spoon formula feeding, and weighed 7 kg (50th centile). This is the first report of the association interstitial 8q21.13q21.2 duplication, which includes OMIM genes (

Abstract	An interstitial pregnancy is an ectopic pregnancy located within the proximal intramural segment of the Fallopian tube traversing the myometrium. This type of ectopic pregnancy is relatively rare, occurring in approximately 1%-3% of all ectopic pregnancies. Given the myometrial mantle surrounding the gestational sac, which is considerably thicker than in other tubal pregnancies, patients with interstitial pregnancies classically manifest symptoms later in gestation. Thus, there is an increased risk of life-threatening intraperitoneal hemorrhage upon rupture of the myometrium encompassing the pregnancy. We present an unusual case of early sonographic diagnosis of an interstitial pregnancy in an asymptomatic patient at 7 and 3/7 weeks' gestation, discuss predisposing factors, hallmarks of sonographic diagnosis, and review the literature regarding available clinical management modalities. With the increasing application of point of care ultrasound (POCUS) by emergency room physicians and other providers in outpatient facilities, our case emphasizes both the importance of correct sonographic identification of interstitial pregnancy and the clinical importance of uniform early first-trimester sonography, preferably no later than 7-8 weeks' gestation.
