Objectives: To summarize image quality variables for alloimmunized women at risk for fetal anemia. To investigate the association between image quality with the highest and median middle cerebral artery peak systolic velocity (MCA-PSV) at the last visit and fetal anemia based on hemoglobin.
Study Design: This study was a qualitative retrospective analysis of 192 Doppler ultrasound images used in the detection of fetal anemia in 26 alloimmunized women seen in a Minneapolis hospital over the past 3 years.

Background: The optimal timing of induction for those undergoing a trial of labor after cesarean section has not been established. The little data which supports the consideration of induction at 39 weeks gestation excludes those with a history of prior cesarean section.
Objective: To determine the risks and benefits of elective induction of labor (IOL) at 39 weeks compared with expectant management (EM) until 42 weeks in pregnancies complicated by one previous cesarean delivery.
Background: Accurate assessment of fetal size is essential in providing optimal prenatal care. National Institute of Child Health and Human Development (NICHD) study from 2015 demonstrated that estimated fetal weight (EFW) differed significantly by race/ethnicity after 20 weeks. There is a large Somali population residing in Minnesota, many of whom are cared for at our maternal fetal medicine practice at the University of Minnesota.

Methods: Fetal exposure was estimated based on transfusion volume and metal concentration in donor packed red blood cell (PRBCs).

Down syndrome (DS) is associated with significant risk of perinatal mortality. We hypothesize that this association is primarily mediated through the effects of fetal growth restriction (FGR). This was a retrospective cohort analysis using the US Natality Database from 2011 to 2013.

Therefore, we sought to determine if trial of labor after cesarean section (TOLAC) will lead to higher maternal and neonatal complications compared to repeat cesarean section (RCD).
Methods: This was a retrospective cohort analysis of singleton nonanomalous births between 37 and 42 weeks GA complicated by maternal obesity (body mass index (BMI) ≥ 30 kg/m) and history of one or two previous cesarean deliveries.
Objective: Ventriculomegaly is the most common fetal brain anomaly identified during prenatal anatomy ultrasound. The aim of our study was to characterize cases of mild ventriculomegaly and investigate the utility of ancillary tests.
Method: We reviewed 121 cases of mild ventriculomegaly, defined as lateral ventricle diameter of 10 to 15 mm.
Objective: To describe the risk of adverse outcomes associated with uterine rupture in the setting of maternal obesity.
Methods: This was a retrospective cohort analysis of singleton nonanomalous neonates born after uterine rupture between 34 and 42 weeks of gestation. We derived data from the U.
Objectives: To determine reference values for sonography-based estimated fetal weight (EFW) in twin gestations in one single tertiary medical center in the United States.
Methods: A retrospective longitudinal analysis of EFW evaluations of fetuses of twin gestations between November 2006 and June 2016. Fetuses with major congenital anomalies or chromosomal abnormalities were excluded.

Objective: To determine whether a reinforcing cerclage (RC) for a short cervix measured after the primary cerclage procedure prolonged pregnancy.
Methods: We conducted a retrospective cohort study of 157 women with singleton gestations who underwent cerclage for standard indications. Women were grouped according to cervical length (CL) at the time of follow-up 1-2 weeks after the initial cerclage placement: ≥25 mm (106 women) and <25 mm with (20 women) or without RC (31 women).

Prenatal glucocorticoid administration in clinically relevant doses reduces nephron number and renal function in adulthood and is associated with hypertension. Nephron loss in early life may predispose the kidney to other insults later but whether sex influences increases in renal susceptibility is unclear. Therefore, we determined, in male and female adult sheep, whether antenatal glucocorticoid (betamethasone) exposure increased 8-isoprostane (marker of oxidative stress) and protein excretion after acute nephron reduction and intrarenal infusions of angiotensin peptides.

Antenatal corticosteroid exposure reduces renal function and alters the intrarenal renin-angiotensin system to favor angiotensin activation of angiotensin type 1 receptor (AT1R) mediated responses in ovine offspring. This study aimed to assess whether antenatal steroid exposure would affect renal responses to the direct intrarenal infusion of angiotensin-(1-7) in rams and the angiotensin receptors involved in mediating responses to the peptide. Adult, uninephrectomized rams exposed to either betamethasone or vehicle before birth received intrarenal angiotensin-(1-7) infusions (1 ng/kg/min) alone or in combination with antagonists to angiotensin receptors for 3 h.

Purpose Of Review: Migraine is a frequent event among women of reproductive age. It is difficult to predict the course and severity of disease that migraineurs will endure during pregnancy. Treatment is often compromised during pregnancy because of concerns regarding pharmacotherapy and fetal well being.

This is a secondary analysis of a randomized trial in laboring, low-risk, nulliparous women at >or=36 weeks' gestation. Neonatal outcomes after use of forceps, vacuum, and cesarean were compared among women in the second stage of labor at station +1 or below (thirds scale) for failure of descent or nonreassuring fetal status.

Antenatal corticosteroids may have long-term effects on renal development which have not been clearly defined. Our objective was to compare the responses to intrarenal infusions of ANG II in two groups of year-old, male sheep: one group exposed to a clinically relevant dose of betamethasone before birth and one not exposed. We wished to test the hypothesis that antenatal steroid exposure would enhance renal responses to ANG II in adult life.

Women of reproductive age are liable to develop their first migraine while pregnant or exhibit changes in the character, frequency or severity of their headaches during pregnancy and the puerperium. The purpose of this Review is to examine the pathophysiology underlying the development of migraine headaches and the association of this pathophysiology with pregnancy-related complications.

We evaluated triploid pregnancy to determine whether there are clinically important differences between the three karyotypes: 69,XXX, 69,XXY, and 69,XYY. Prospectively maintained cytogenetic databases at five tertiary care centers were retrospectively reviewed over a 10-year period to identify all triploid pregnancies. Targeted ultrasounds were reviewed to identify fetal and placental findings.

Methods: A retrospective review of all cases of trisomy 9 at 5 participating institutions over a 15-year interval was conducted. Indications for referral and sonographic findings in each case were reviewed to identify characteristic fetal structural anomalies.
We sought to identify the characteristic sonographic findings of fetal trisomy 22 by performing a retrospective review of nine cases of fetal trisomy 22. All cases of chromosomal mosaicism were excluded, as were first-trimester losses. Indications for sonography, gestational age, and sonographically detected fetal anomalies were analyzed.

We question the application of array findings across the major categories of cervical cancer. We sought to identify differences between normal squamous epithelium (NSQ) and glandular epithelium (NGL) of the uterine cervix and their malignant variants: squamous cell cancer (SCC) and adenocarcinoma (ACA).
