Feasibility of Universal Screening for Preeclampsia Risk and Aspirin Recommendation in the Ultrasound Unit.

OBJECTIVE: To evaluate the feasibility and impact of using the first-trimester ultrasound visit to identify and counsel women at increased risk of preeclampsia about the benefits of low-dose aspirin (LDA) for preventing preeclampsia. We also assessed patient-reported utilization of LDA, perceived risk for preeclampsia, and clinical outcomes. STUDY DESIGN: Women presenting for routine first-trimester nuchal-translucency (NT) ultrasounds were screened for clinical preeclampsia risks using a self-administered risk assessment. Women at moderate or high risk for preeclampsia were counseled to take LDA, if not already taking it. LDA utilization and perceived risk for preeclampsia were assessed during the second-trimester ultrasound. Factors associated with LDA utilization were analyzed. Pregnancy outcomes were compared between those who used LDA and those who did not. RESULTS: Slightly more than 20% of patients (765/3,669) screened at increased risk for developing preeclampsia. Of those, 67.8% (519/765) had not received LDA recommendations from their referring obstetrician and 97 had not been taking LDA despite being advised to do so. Combined, 94.6% (583/616) of these patients eligible to start LDA prophylaxis received the indicated counseling during the ultrasound visit. A total of 61.4% (358/583) of women completed the follow-up form and of those 77.9% (279/358) reported taking LDA. Screening at increased risk for preeclampsia and perception of increased risk were positively associated with LDA utilization, whereas concerns for LDA safety were negatively associated with use. African American/Black patients and Medicaid recipients were less likely to use LDA. Pregnancy outcomes were similar between those who used LDA and those who did not. CONCLUSION: Assessing preeclampsia risk and counseling patients about LDA at the time of the NT ultrasound are feasible in the ultrasound unit and led to good LDA utilization among women at increased risk for preeclampsia. This intervention may standardize patient care and help close the disparity in maternal health. KEY POINTS: · A simple intervention captured 2/3 of eligible patients.. · Aspirin utilization rate was good after the intervention.. · Screening high risk for preeclampsia and self-perception of risk correlated with aspirin use..

Preterm prelabor rupture of membranes in singletons: maternal and neonatal outcomes.

OBJECTIVES: To determine the effect of gestational age at delivery on maternal and neonatal outcomes in preterm prelabor rupture of membranes (PPROM) and assess various predictors of neonatal and infant mortality in these pregnancies. METHODS: United States birth data from CDC-National Center for Health Statistics natality database for years 2004-2008 was used to identify singleton pregnancies with PPROM and delivery from 32 0/7 to 36 6/7 weeks. Controls were singletons at 37-40 weeks, without PPROM. Maternal and neonatal complications reported by all states were analyzed along with neonatal outcomes such as chorioamnionitis and hyaline membrane disease, reported by a subgroup of states. OR (95% CI) were calculated after adjusting for preeclampsia, diabetes, chronic hypertension, maternal race, and infant sex. RESULTS: There were 134,502 PPROM cases and similar number of controls. There was a significant decrease in need for prolonged ventilation, hyaline membrane disease, 5 min Apgar score <7, and NICU admission with advancing gestational age. Placental abruption decreased and chorioamnionitis and cord prolapse were not different between 34 and 37 weeks. We found reductions in early death, neonatal death, and infant mortality with advancing gestational age (p<0.001 for each). Gestational age at delivery was the strongest predictor for early death, neonatal death, and infant mortality in PPROM. These differences persisted after adjusting for antenatal steroid use. CONCLUSIONS: We provide population-based evidence showing a decrease in neonatal complications and death with advancing gestational age in PPROM. Gestational age at delivery in pregnancies with PPROM is the strongest predictor of mortality risk.

Improving fetal congenital heart disease screening using a checklist-based approach.

To determine if using a checklist of specific ultrasound image criteria to screen the fetal heart improves the cardiac exam completion rate, defined as the ability to classify the heart as normal or abnormal. This is a retrospective cohort study of patients with singleton pregnancies who underwent a fetal anatomy survey between 18 and 28 weeks' gestation. A checklist was used from 1 September 2015 to 31 March 2016 to categorize exams as complete-normal, complete-abnormal, or incomplete. Performance was compared with a 7-month period prior to checklist introduction (1 December 2014 to 30 June 2015). Checklist utilization improved the cardiac exam completion rate by 8.9%. With the checklist, 1083 of 1202 exams (90.1%) were completed compared to 987 of 1193 (82.7%) pre-checklist, P < .001. We did not detect a change in cases classified as abnormal and referred for echocardiography: 25 (2.1%) with the checklist and 16 (1.3%) pre-checklist, P = .16. We did not detect more congenital heart disease (CHD), 12 (1.0%) with checklist screening, 5 (0.4%) pre-checklist, P = .14. Critical CHD was not missed in either group. Using the checklist improved the cardiac exam completion rate. There was no change in congenital heart disease detection.

Isolated Single Umbilical Artery and Fetal Echocardiography: A 25-Year Experience at a Tertiary Care City Hospital.

OBJECTIVES: To review our 25-year experience with a single umbilical artery and fetal echocardiography to estimate the need for this test in cases of an isolated single umbilical artery. METHODS: We conducted a retrospective review of 436 patients with a diagnosis of a single umbilical artery at our institution between 1990 and 2015. Two hundred eighty-eight women had both an anatomic survey and a fetal echocardiogram. Pregnancies with concurrent extracardiac anomalies or aneuploidy were excluded. The study population was divided into 3 groups based on cardiac views on the anatomic survey: normal, incomplete, and suspicious. Echocardiographic results were compared among the 3 groups. The primary outcome measure was the incidence of cardiac anomalies in the normal group at fetal echocardiography. The data were analyzed by the χ2 test or Fisher exact test. RESULTS: The mean maternal age ± SD of the group was 29.2 ± 6.2 years; 44.1% were primiparas. The mean gestational age at diagnosis was 22.6 ± 5.2 weeks, and the mean gestational age at fetal echocardiography was 25.1 ± 3.6 weeks. In the normal group, 99.1% (230 of 232) of women had a normal fetal echocardiogram; the 2 abnormal cases were ventricular septal defects. Normal echocardiograms were obtained in 81.8% (36 of 44) and 25.0% (3 of 12) of the "incomplete" and "suspicious" groups, respectively. CONCLUSIONS: Fetuses with a single umbilical artery, in the absence of structural abnormalities, and with normal cardiac views at the time of the anatomic survey do not warrant an echocardiogram.

Characterization of a presymptomatic stage in a Drosophila Parkinson's disease model: Unveiling dopaminergic compensatory mechanisms.

Parkinson's disease (PD) is a degenerative disorder characterized by several motor symptoms including shaking, rigidity, slow movement and difficult walking, which has been associated to the death of nigro-striatal dopaminergic neurons. >90% of PD patients also present olfactory dysfunction. Although the molecular mechanisms responsible for this disease are not clear, hereditary PD is linked to mutations in specific genes, including the PTEN-induced putative kinase 1 (PINK1). In this work we provide for the first time a thorough temporal description of the behavioral effects induced by a mutation in the PINK1 gene in adult Drosophila, a previously described animal model for PD. Our data suggests that the motor deficits associated to PD are fully revealed only by the third week of age. However, olfactory dysfunction is detected as early as the first week of age. We also provide immunofluorescence and neurochemical data that let us propose for the first time the idea that compensatory changes occur in this Drosophila model for PD. These compensatory changes are associated to specific components of the dopaminergic system: the biosynthetic enzymes, Tyrosine hydroxylase and Dopa decarboxylase, and the Dopamine transporter, a plasma membrane protein involved in maintaining dopamine extracellular levels at physiologically relevant levels. Thus, our behavioral, immunofluorescence and neurochemical data help define for the first time presymptomatic and symptomatic phases in this PD animal model, and that compensatory changes occur in the dopaminergic neurons in the presymptomatic stage.

Effects of Endometrial Ablation on Treatment Planning in Women With Endometrial Cancer.

To evaluate effects of endometrial ablation on the staging and treatment planning of postablation endometrial cancer. After authorization from the institutional review board, we performed a retrospective chart review of patients with a history of endometrial ablation and a subsequent diagnosis of endometrial cancer from July 2006 to December 2013. The information obtained included patient's age at time of cancer diagnosis, pre-ablation endometrial biopsy histology, dilation and curettage histology at time of ablation, endometrial biopsy-to-ablation interval, ablation-to-hysterectomy interval, final pathologic diagnosis, Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) staging, and treatment recommendations for adjuvant therapy. The histopathology was examined by a gynecologic pathologist. The National Comprehensive Cancer Network guidelines were applied to determine need for adjuvant therapy. Six of 490 (1.2%) patients with endometrial cancer were identified to have an antecedent ablation. Mean patient age was 48.2 years (range: 40-53). The time interval from office pre-ablation endometrial sampling to ablation ranged from 1 to 17 months. Four patients (67%) had an undetected endometrial cancer at the time of ablation, despite having benign pre-ablation histology. Following surgical staging, 4 patients (67%) had no evidence of residual carcinoma, and 2 (33%) had evidence of endometrial adenocarcinoma grades 1 to 2. There was no evidence of myometrial invasion in all cases, and a FIGO stage of IA was assigned. No adjuvant therapies were indicated. There have been no documented cancer recurrences, with a follow-up range from 16 to 52 months (average 30.2). Endometrial ablation artifact does not appear to hinder evaluation and treatment planning in the presence of endometrial cancer.

Interstitial twin pregnancy: A unique case presentation.

Early recognition and timely treatment of an interstitial pregnancy is imperative to avoid the high morbidity and mortality of this type of ectopic pregnancy. We report a case of twin interstitial pregnancy that was initially missed on initial sonogram and was subsequently recognized at our institution by transvaginal sonography. The patient underwent open laparoscopic surgery with cornual wedge resection but suffered infundibulopelvic ligament hemorrhage and subsequently required ipsilateral salpingo-oophorectomy. She did well and was discharged home a day later.

Impact of noninvasive prenatal testing in regionally dispersed medical centers in the United States.

OBJECTIVE: Noninvasive prenatal testing using cell-free DNA is a new alternative to screen for common fetal aneuploidies. It is not known what impact regional location may play on noninvasive prenatal testing implementation and downstream invasive prenatal procedure use in the United States. STUDY DESIGN: Six different regionally based centers collected data on noninvasive prenatal testing indication and results between February and November 2012, as well as their invasive prenatal procedure rates before and after offering noninvasive prenatal testing. Statistical analyses were performed using the 2-proportion Z-test. RESULTS: Of 1477 patients who underwent noninvasive prenatal testing; 693 (47%) were from centers in the West; 522 (35.3%) from centers in the East; and 262 (17.7%) from 1 center in the Midwest. Statistically significant differences were observed between West Coast and nonWest Coast sites for gestational age (14.1 weeks; P ≤ .0001). Advanced maternal age (AMA-only) was the most frequent indication in 5 of 6 sites (range, 21.8-62.9%) A total of 98 invasive prenatal procedures performed on 94 (6.4%) patients of which 64 (65.3%) were performed at centers in the West. More invasive procedures were performed following negative noninvasive prenatal testing results (n = 61) than abnormal noninvasive prenatal testing results (n = 30). The overall rate of patients undergoing invasive procedure after an abnormal noninvasive prenatal testing result was 32.6% (30 of 92). All 6 centers reported a decrease in invasive procedure volume after noninvasive prenatal testing introduction. CONCLUSION: This study demonstrates differences in clinical implementation of noninvasive prenatal testing across regionally dispersed centers in the United States, suggesting patient demographics and views toward prenatal testing influence use as well as downstream management.

First-trimester sonographic prediction of obstetric and neonatal outcomes in monochorionic diamniotic twin pregnancies.

OBJECTIVES: The purpose of this study was to investigate whether discordant nuchal translucency and crown-rump length measurements in monochorionic diamniotic twins are predictive of adverse obstetric and neonatal outcomes. METHODS: We conducted a multicenter retrospective cohort study including all monochorionic diamniotic twin pregnancies with two live fetuses at the 11-week to 13-week 6-day sonographic examination who had serial follow-up sonography until delivery. Isolated nuchal translucency, crown-rump length, and combined discordances were correlated with adverse obstetric outcomes, individually and in composite, including the occurrence of 1 or more of the following in either fetus: intrauterine growth restriction (IUGR), twin-twin transfusion syndrome (TTTS), intrauterine fetal death (IUFD), growth discordance (≥ 20%), and preterm birth before 28 weeks' gestation. Correlations with adverse composite neonatal outcomes were also studied. A receiver operating characteristic curve analysis and a logistic regression analysis with a generalized estimating equation were conducted. RESULTS: Fifty-four of the 177 pregnancies included (31%) had an adverse composite obstetric outcome, with TTTS in 19 (11%), IUGR in 21 (12%), discordant growth in 14 (8%), IUFD in 14 (8%), and preterm birth before 28 weeks in 10 (6%). Of the 254 neonates included in the study, 69 (27%) were complicated by adverse composite neonatal outcomes, with respiratory distress syndrome being the most common (n = 59 [23%]). The areas under the curve for the combined discordances to predict composite obstetric and neonatal outcomes were 0.62 (95% confidence interval, 0.52-0.72), and 0.54 (95% confidence interval, 0.46-0.61), respectively. CONCLUSIONS: In our population, nuchal translucency, crown-rump length, and combined discordances in monochorionic diamniotic twin pregnancies were not predictive of adverse composite obstetric and neonatal outcomes.

Does early second-trimester sonography predict adverse perinatal outcomes in monochorionic diamniotic twin pregnancies?

OBJECTIVES: To determine whether intertwin discordant abdominal circumference, femur length, head circumference, and estimated fetal weight sonographic measurements in early second-trimester monochorionic diamniotic twins predict adverse obstetric and neonatal outcomes. METHODS: We conducted a multicenter retrospective cohort study involving 9 regional perinatal centers in the United States. We examined the records of all monochorionic diamniotic twin pregnancies with two live fetuses at the 16- to 18-week sonographic examination who had serial follow-up sonography until delivery. The intertwin discordance in abdominal circumference, femur length, head circumference, and estimated fetal weight was calculated as the difference between the two fetuses, expressed as a percentage of the larger using the 16- to 18-week sonographic measurements. An adverse composite obstetric outcome was defined as the occurrence of 1 or more of the following in either fetus: intrauterine growth restriction, twin-twin transfusion syndrome, intrauterine fetal death, abnormal growth discordance (≥20% difference), and very preterm birth at or before 28 weeks. An adverse composite neonatal outcome was defined as the occurrence of 1 or more of the following: respiratory distress syndrome, any stage of intraventricular hemorrhage, 5-minute Apgar score less than 7, necrotizing enterocolitis, culture-proven early-onset sepsis, and neonatal death. Receiver operating characteristic and logistic regression-with-generalized estimating equation analyses were constructed. RESULTS: Among the 177 monochorionic diamniotic twin pregnancies analyzed, intertwin abdominal circumference and estimated fetal weight discordances were only predictive of adverse composite obstetric outcomes (areas under the curve, 79% and 80%, respectively). Receiver operating characteristic curves showed that intertwin discordances in abdominal circumference, femur length, head circumference, and estimated fetal weight were not acceptable predictors of twin-twin transfusion syndrome or adverse neonatal outcomes. CONCLUSIONS: In our cohort, only second-trimester abdominal circumference and estimated fetal weight discordances in monochorionic diamniotic twin pregnancies were predictive of adverse composite obstetric outcomes. Twin-twin transfusion syndrome and adverse neonatal outcomes were not predicted by any of the intertwin discordances measured.

Severe skeletal dysplasia caused by a novel FLNB gene mutation.

A late adolescent primigravida was found to have a fetus with a cystic hygroma and significant shortening of the limbs on first-trimester ultrasound. She underwent chorionic villus sampling with normal microarray result. In the early second trimester, the fetus was found to have the absence of all four limbs and a thorough skeletal dysplasia workup was pursued, identifying a variant in the FLNB gene (c.62C>G). The patient underwent termination of pregnancy. The care of this patient was expedited by first-trimester sonographic evidence of limb abnormalities enabling timely clinical management.

Antenatal fetal surveillance of women with severe obesity.

OBJECTIVE: To estimate the impact of body mass index (BMI) categories on duration of the nonstress test (NST), and the need for additional tests of fetal wellbeing or interventions. METHODS: We conducted a retrospective cohort study of women with singleton pregnancies who had an NST for the indications of severe obesity (BMI ≥40 kg/m2), diabetes (pre-gestational or gestational), hypertensive disorders (chronic, gestational, and preeclampsia), and others between 1 January 2015 until 31 December 2016. NST durations (<30 and ≥30 min) were compared between groups first based on BMI (kg/m2) categories (<30, 30-39, 40-49, and ≥50) and then based on BMI and comorbidities: (1) severe obesity alone, (2) severe obesity and comorbidities, and (3) comorbidities alone. We compared the results of the NSTs, any subsequent fetal testing or interventions, and pregnancy outcomes among groups. Demographic information was compared using t-tests for continuous data and χ2 analyses or Fisher's exact test, if the cells sizes were small, for categorical data. NST durations based on BMI groups, as well as BMI and comorbidities groups, were compared using linear mixed models and ANOVA. RESULTS: Three hundred and fifty-one women underwent 1665 NSTs during the study period. After excluding women <18 and >50 years, gestational age <30 weeks, fetal anomalies, and NSTs lasting longer than 60 min, the study population included 313 women and 1471 NSTs. The mean NST duration in minutes of the BMI ≥50 (32.2 ± 9.6) category was significantly longer than the NST duration of the other BMI categories (BMI <30: 29.4 ± 8.3; BMI 30-39: 29.7 ± 8.9; BMI 40-49: 29.9 ± 8.3) (p=.05). Additionally, there was an increased percentage of NSTs lasting ≥30 min as the BMI category increased (p=.005). Women in the severe obesity and comorbidities group (n = 79) were less likely to have a reactive NST than women with severe obesity alone (n = 56) or comorbidities alone (n = 178) (92% vs. 97% vs. 98%, p<.0001). They were also more likely to need a biophysical profile (BPP) (8% vs. 3% vs. 2%, p<.0001). Of the 25 women that were sent to the labor and delivery unit for evaluation, 20 (80%) were admitted and delivered. The reasons for delivery were hypertension (n = 9, 45%), an abnormal NST (n = 5, 25%), oligohydramnios (n = 4, 20%), and labor (n = 2, 10%). CONCLUSIONS: We found an increase in NST duration as the BMI increased. Women with severe obesity and a comorbidity were more likely to have a nonreactive NST and require a subsequent BPP. Of the 20 patients delivered due to NST surveillance, the most common indication for delivery was hypertension.

Perception of the impact of maternal weight on pregnancy outcomes in overweight and obese women.

OBJECTIVE: The purpose of this study was to assess and compare knowledge, self-awareness, and accuracy of perceived risks and weight status among overweight and obese women. METHODS: This study was a secondary analysis of a cross-sectional questionnaire study of overweight and obese pregnant women who sought a routine first-trimester screening ultrasound. Those with a pre-pregnancy body mass index (BMI) ≥25 kg/m2 (calculated using self-reported height and weight) were included. Perceived associations between estimated weight category and risk of pregnancy complications were assessed and compared in the overweight and obese groups. The perceived weight category was compared to an estimated weight category. A logistic regression identified the demographic and medical factors associated with correct identification of risk factors. RESULTS: A total of 169 participants (88 overweight; 81 obese) were included. Most participants believed their weight did not impact the ultrasound detection of a fetal malformation (92.1% overweight vs. 55.6% obese, p < .01). Few participants associated their weight with pregnancy-related problems (6.8% overweight vs. 24.7% obese, p < .01). Most participants did not associate their weight with specific maternal complications (72.7% overweight vs. 45.7% obese, p < .01) and fetal complications (83.0% overweight vs. 71.6% obese, p = .08). More obese than overweight women underestimated their weight category (64.4% vs 41.3% overweight, p = .01). Women who correctly estimated their weight status, non-Hispanic participants, and those with a history of depression or at least one maternal co-morbidity were more likely to associate their weight with increased risk for pregnancy-related problems. CONCLUSION: Although more obese than overweight women associated excess weight with pregnancy complications, both groups underestimated the impact on their pregnancies. Targeted educational programs are needed to improve the risk perception of these populations prior to pregnancy with the goal of improving their weight statuses and pregnancy outcomes.

Intrahepatic cholestasis of pregnancy: dilemma in diagnosis and management.

OBJECTIVE: To determine the obstetrical outcomes of women delivered for the diagnosis of intrahepatic cholestasis of pregnancy (ICP). METHODS: Retrospective study of singleton pregnancies diagnosed with ICP between 1 May 2014 and 31 December 2017. Population was analyzed based on bile acids: normal (<10 µmol/L), mild (10 to 40 µmol/L), moderate-severe (>40 µmol/L), and not obtained. Receiver operating characteristic curves established critical values for aspartate aminotransferase (AST) and alanine aminotransferase (ALT) to predict elevated bile acids. Statistical analyses included χ2 for categorical variables and ANOVA for continuous variables. All tests used a 2-sided α level of significance of .05. RESULTS: Bile acids were normal in 39 (45.9%) women, 30 (35.3%) had mild cholestasis, 10 (11.8%) had moderate-severe cholestasis and not obtained for six (7%) women. Gestational diabetes was more common in mild cholestasis (p = .03). There were no differences in demographics, clinical presentation, obstetric interventions and neonatal outcomes. Bile acids took 5-6 days to result. Rate of labor inductions was high in all groups. Postpartum complications occurred in four women in the normal group and in one woman in the mild cholestasis group. Five (12.8%) neonates in the normal group, six (20%) in the mild group, and one (10%) in the severe group were admitted to the NICU. There was no fetal asphyxia, no 5-minute Apgar score <7, and no perinatal deaths. An AST of 27.5 IU/L (p = .002) with sensitivity of 81% and specificity of 76%, and an ALT of 26.7 IU/L (p = .004) with sensitivity of 78% and specificity of 68% predicted elevated bile acids. Improving the sensitivity of AST and ALT to 95%, the ROC curve identified an AST of 62 IU/L with a specificity, positive and negative predictive values of 32, 58 and 86%, respectively; and an ALT of 106 IU/L with a specificity, positive and negative predictive values of 27, 57 and 83%, respectively. CONCLUSIONS: ICP should not be presumed in patients with pruritus. This practice may lead to early term delivery and associated complications.

Abnormal distribution of inositol 1,4,5-trisphosphate receptors in human muscle can be related to altered calcium signals and gene expression in Duchenne dystrophy-derived cells.

Inositol 1,4,5-trisphosphate (IP(3)) receptors (IP(3)Rs) drive calcium signals involved in skeletal muscle excitation-transcription coupling and plasticity; IP(3)R subtype distribution and downstream events evoked by their activation have not been studied in human muscle nor has their possible alteration in Duchenne muscular dystrophy (DMD). We studied the expression and localization of IP(3)R subtypes in normal and DMD human muscle and in normal (RCMH) and dystrophic (RCDMD) human muscle cell lines. In normal muscle, both type 1 IP(3)Rs (IP(3)R1) and type 2 IP(3)Rs (IP(3)R2) show a higher expression in type II fibers, whereas type 3 IP(3)Rs (IP(3)R3) show uniform distribution. In DMD biopsies, all fibers display a homogeneous IP(3)R2 label, whereas 24 +/- 7% of type II fibers have lost the IP(3)R1 label. RCDMD cells show 5-fold overexpression of IP(3)R2 and down-regulation of IP(3)R3 compared with RCMH cells. A tetanic stimulus induces IP(3)-dependent slow Ca(2+) transients significantly larger and faster in RCDMD cells than in RCMH cells as well as significant ERK1/2 phosphorylation in normal but not in dystrophic cells. Excitation-driven gene expression was different among cell lines; 44 common genes were repressed in RCMH cells and expressed in RCDMD cells or vice versa. IP(3)-dependent Ca(2+) release may play a significant role in DMD pathophysiology.

How much free fluid can a pregnant patient have? Assessment of pelvic free fluid in pregnant patients without antecedent trauma.

BACKGROUND: The amount of free fluid that can normally be present in a pregnant patient is unknown. Evaluation of pelvic free fluid in a population of pregnant patients without early history of trauma would help determine what amount of free fluid should raise suspicion of intra-abdominal injury in those who have suffered trauma. METHODS: Patients presenting for routine obstetric ultrasound without an early history of trauma were offered participation in the study. Routine imaging of the cul de sac and ovaries was used for assessment of presence or absence of free fluid, with accompanying digitally recorded images. Depth of the fluid pocket was measured in millimeters. RESULTS: Six of 89 patients successfully scanned were found to have free fluid in to the cul de sac for an occurrence of 6.7%. Four patients had free fluid present during the first trimester with subsequent resolution by the late first trimester or early second trimester. Two of these patients had an identifiable cause for free fluid, one with right ovarian hyperstimulation and the second with idiopathic theca lutein cysts. Two patients had isolated free fluid appearing in the third trimester. CONCLUSIONS: These results suggest that the presence of pelvic free fluid in pregnant patients without antecedent trauma is very low. After blunt abdominal trauma, the presence of free fluid in the pelvis of a pregnant patient may not be physiologic, especially if there is >2 mm to 4 mm, and there is no history of ovarian hyperstimulation syndrome or other known associations.

HSV serologic testing for pregnant women: willingness to be tested and factors affecting testing.

OBJECTIVE: This prospective study was undertaken to evaluate pregnant women's willingness to undergo HSV type-specific serologic testing and factors affecting willingness in an obstetrics/gynecology ambulatory unit. METHODS: At prenatal Visit 1, pregnant women (n = 303) with no history of HSV-2 were tested for HSV-1/HSV-2 before and after they received counseling on genital and neonatal herpes. RESULTS: In both the Unwilling Subgroup and the group that changed from being willing to being unwilling, the most common reasons for choosing not to be tested were not being at risk for genital herpes, being tested is too personal, and concern about what will be done with the results. Of the 134 participants in the Willing/Tested Subgroup, 27 (20%) were HSV-2 seropositive and 81 (60%) were HSV-1 seropositive. Conclusions. These results support the feasibility of HSV serologic testing and counseling in pregnant women.

Ethnic Disparities in Coronavirus Disease 2019 after the Implementation of Universal Screening in Hartford, Connecticut.

Objective The aim of this article was to estimate the prevalence of coronavirus disease 2019 (COVID-19) in Connecticut, examine racial/ethnic disparities, and assess pregnancy outcomes in pregnant women following the implementation of universal screening for the virus. Materials and methods This is a retrospective cohort study of all obstetric patients admitted to our labor and delivery unit during the first 4 weeks of implementation of universal screening of COVID-19. Viral studies were performed in all neonates born to mothers with severe acute respiratory syndrome coronavirus 2. We calculated the prevalence of COVID-19, compared the baseline characteristics and pregnancy outcomes between those who tested positive and negative for the virus, and determined the factors associated with COVID-19. Results A total of 10 (4.6%) of 220 women screened positive for the virus. All were asymptomatic. Week 1 had the highest prevalence of infection, nearing 8%. No neonates were infected. Hispanics were more likely to test positive (odds ratio: 10.23; confidence interval: [2.71-49.1], p = 0.001). Obstetric and neonatal outcomes were similar between the groups ( p > 0.05). Conclusion Although the rate of asymptomatic COVID-19 was low, ethnic disparities were present with Hispanics being more likely to have the infection. Key Points 4.6% of pregnant women in labor and delivery tested positive for COVID-19 while being asymptomatic.Hispanic women were more likely to test positive for severe acute respiratory syndrome coronavirus 2.Pregnancy outcomes were similar between COVID-19 positive and negative women.No vertical transmission was detected.

Romiplostim for management of refractory immune thrombocytopenic purpura in the immediate postpartum period.

We present a case of a pregnant woman with chronic immune thrombocytopenic purpura and chronic hypertension who developed pre-eclampsia with severe features warranting delivery. Her overall clinical picture and liver enzymes improved in the immediate postpartum period, however, aggressively progressing thrombocytopenia posed a diagnostic dilemma to the interdisciplinary care team. After failing to respond to first-line therapies including high-dose corticosteroids and intravenous immunoglobulin, she was successfully managed with a trial of the thrombopoietin receptor agonist, Romiplostim.
