Psychological impact of the detection of soft markers on routine ultrasound scanning: a pilot study investigating the modifying role of information

Isolated choroid plexus cysts and health and developmental outcomes in childhood and adolescence - A systematic review

OBJECTIVES

Choroid plexus cysts (CPCs) are incidental findings on ultrasound examination of the fetal brain. It is not known if isolated CPCs are associated with any adverse health or neurodevelopmental outcomes during the life course. This systematic review aimed to collate and synthesize the evidence on whether or not isolated choroid plexus cysts are associated with an increased risk of adverse health or developmental outcomes during childhood and adolescence.

METHODS

A search strategy was developed specifically for this study and applied to four electronic databases Medline (Ovid), Embase (Ovid), Web of Science, and Google Scholar. Studies were assessed and selected for inclusion if there was a measurement of CPC (including single or multiple; unilateral or bilateral; isolated or presenting alongside other markers) during the antenatal or early neonatal period (<7 days) with follow-up of children and adolescents for health and developmental outcomes measured at any time from age 1 month onwards. Study quality was assessed using the Newcastle-Ottawa Quality Assessment Scale. Due to heterogeneity in the types of outcome measures included and the timing of measurement of outcomes across the studies, it was not possible to pool data across studies and a narrative description of findings was presented.

RESULTS

Eight studies (three cohorts and five case series) met the inclusion criteria. Different methods were used for outcome assessment, such as in-person assessment, parent questionnaires, medical records, and telephone interviews with parents. Six studies measured outcomes only once during the specified duration of follow-up; two studies carried out paediatric reviews of the children several times during follow-up. There were no differences in developmental outcomes or physical health between babies with CPCs reported in the three cohort studies, and no abnormalities were detected in the children that were followed up in four of the five case series studies. Most of the included studies were graded as low quality due to the small sample size, high risk of selection bias, unclear definitions of CPC or lack of a comparison group.

CONCLUSIONS

The studies conducted to date do not provide evidence of adverse physical health outcomes or neurodevelopmental delays in babies with CPCs. However, most of these studies were small and included a narrow range of outcomes. Further research is needed to explore the relative incidence of outcomes such as ASD, ADHD, epilepsy and educational attainment in children with CPCs.

"Motherese" Prosody in Fetal-Directed Speech: An Exploratory Study Using Automatic Social Signal Processing

Introduction: Motherese, or emotional infant directed speech (IDS), is the specific form of speech used by parents to address their infants. The prosody of IDS has affective properties, expresses caregiver involvement, is a marker of caregiver-infant interaction quality. IDS prosodic characteristics can be detected with automatic analysis. We aimed to explore whether pregnant women “speak” to their unborn baby, whether they use motherese while speaking and whether anxio-depressive or obstetrical status impacts speaking to the fetus.

Participants and Methods: We conducted an observational study of pregnant women with gestational ages from 26 to 38 weeks. Women were recruited in a university hospital department of obstetrics. Thirty-five women agreed to participate in the study, and 26 audio records were exploitable. We collected obstetrical and sociodemographic data, pregnancy outcomes, anxiety and depressive status using the Covy and Raskin Scales, and life events using the Sensations During Pregnancy and Life Event Questionnaire. Each participant was left alone with an audio recorder with a recommendation to feel free to speak to her fetus as she would have done at home. The recording was stopped after 3 min. Audio recordings were analyzed by two methods: psycholinguist experts' annotation and computational objective automatic analyses.

Results: Most mothers (89%) reported speaking to their fetuses. We found a correlation between maternal first perceptions of fetal movements and the start of mother's speaking to fetus. Motherese prosody was detected with both annotation and automatic analysis with a significant correlation between the two methods. In this exploratory study, motherese use was not associated with maternal anxiodepressive or obstetrical status. However, the more future mothers were depressed, the less they spoke with their fetuses during the recording.

Conclusion: Fetal directed speech (FDS) can be detected during pregnancy, and it contains a period of prosody that shares the same characteristics of motherese that can be described as prenatal motherese or emotional fetal-directed speech (e-FDS). This means that pregnant women start using motherese much earlier than expected. FDS seems to be correlated with maternal first perceptions of fetal movements and depression scores. However, more research is needed to confirm these exploratory results.

Indeterminate Prenatal Ultrasounds and Maternal Anxiety: A Prospective Cohort Study

INTRODUCTION

Prenatal ultrasounds often yield indeterminate (incomplete or minor abnormality) findings with limited clinical utility. We evaluate impact of indeterminate findings on maternal anxiety.

METHODS

A single-U.S.-center prospective cohort study administered the Perinatal Anxiety Screening Scale (PASS; control mean = 13.4; > 20 denotes clinically significant anxiety) before and after prenatal ultrasounds in February-May 2017. Ultrasound reports were coded as: normal; indeterminate; or major abnormality. Primary outcome was anxiety after indeterminate vs. normal ultrasounds. Secondary outcomes included anxiety change from pre-to-post-ultrasound and relative to women's characteristics. Linear regression adjusted for confounders.

RESULTS

Of 286 ultrasounds, 51.0% were normal, 40.5% indeterminate (22.0% incomplete; 18.5% minor abnormality), and 8.0% major abnormalities. Indeterminate findings were unrelated to age, race, parity, infertility, or psychiatric history, but associated with gestational age (26.6%/45.0%/52.5% for first/second/third trimesters; p < 0.001), and obesity (48.8 vs. 37.0%; p = 0.031). Pretest anxiety was highest in second/third trimesters (p = 0.029), and in subjects aged age ≤ 24 or younger(p < 0.001), with a history of anxiety (p < 0.001),) or with prior pregnancy loss (p = 0.011). Mean anxiety score decreased pre-to-posttest across all groups. Indeterminate findings were associated with higher PASS scores than normal findings: pretest 20.1 vs. 16.4 (p = 0.026) and posttest 16.9 vs. 12.2 (p = 0.009; adjusted-p = 0.01). Versus normal ultrasounds, incomplete findings were associated with higher post-ultrasound anxiety (p = 0.007; adjusted-p = 0.01) and smaller decreases from pre-to-posttest (adjusted-p = 0.03), whereas minor abnormalities had higher pretest anxiety (p = 0.029) with larger pre-to-posttest decreases (adjusted-p =0.010).

DISCUSSION

Indeterminate ultrasounds, especially incomplete findings, are associated with significantly higher anxiety than normal findings, suggesting need for evidence-based counseling, management and strategies for decreasing number of indeterminate results.

PRENATAL IDENTIFICATION OF ABERRANT RIGHT SUBCLAVIAN ARTERY IN ISOLATION: THE NEED FOR FURTHER GENETIC WORK-UP?

The objective of this study was to evaluate the association between aberrant right subclavian artery (ARSA) and chromosomal abnormalities. The study included 5211 women having attended our unit for fetal anatomic screening and fetal echocardiography from August 2016 until February 2019. After diagnosing ARSA, prenatal invasive testing was discussed with the patients. ARSA affected fetus was determined in 57 cases; of these, there were 38 cases of isolated ARSA and 19 cases of non-isolated ARSA but associated with soft markers and fetal anomalies. Nineteen patients underwent amniocentesis; Down syndrome was determined in two women, both of them from the non-isolated ARSA group, with fetal hydrops, atrioventricular septal defect and esophageal atresia. Fifteen of 38 patients who declined prenatal diagnostic testing, accepted karyotype analysis after delivery and none of these 15 cases had chromosomal abnormalities. Identification of ARSA should be followed by detailed ultrasound examination to ensure that there are no accompanying soft markers and/or structural defects. Isolated ARSA may not be an indication for karyotype analysis or 22q11.2 microdeletions. Non-ARSA implies a strong predictor of aneuploidy, and when additional findings are detected, invasive testing should be offered to the parents. The association between isolated ARSA and genetic disease should be evaluated in large powered prospective studies.

Use of noninvasive prenatal screening with cell-free DNA in late pregnancy with sonographic soft markers

OBJECTIVE

To report the experience on the clinical use of noninvasive cell-free (cf) DNA testing at late pregnancy.

STUDY DESIGN

A cohort of 1539 women with singleton gestations of ≥23 weeks receiving cfDNA testing in a 3-year period were included for this study. Maternal characteristics and data on cfDNA testing, confirming diagnostic testing and pregnancy outcome were reviewed.

RESULTS

During the study period, 1539 patients had cfDNA testing although they had a normal first-trimester screening. Of these, 7 cases had a positive result, including 5 for chromosome 21, one for chromosome 18, and one for chromosome 13. The most common indication was soft markers on ultrasound, followed by polyhydramnios. Cytogenetic testing was done for the 5 trisomy 21 positive cases, and confirmed the cfDNA results. Confirmative testing was declined in the two cases with positive cfDNA for trisomy 18/13, and postnatal placental investigation showed confined placental mosaicism with normal karyotype in the cord blood of newborns. There were no confirmed false negatives reported. The cfDNA screening achieved a positive predictive value of 71.4 % and a negative predictive value of 100 % in late pregnancy for common trisomies.

CONCLUSIONS

There is no gestational age upper limit for cfDNA use in the clinical practice. Most of the time, cfDNA was used in late gestation for reassurance in patients who is at low risk for aneuploidies but had second-trimester soft markers on ultrasound.

Effectiveness and cost-effectiveness of routine third trimester ultrasound screening for intrauterine growth restriction: study protocol of a nationwide stepped wedge cluster-randomized trial in The Netherlands (The IRIS Study)

Background

Intrauterine growth retardation (IUGR) is a major risk factor for perinatal mortality and morbidity. Thus, there is a compelling need to introduce sensitive measures to detect IUGR fetuses. Routine third trimester ultrasonography is increasingly used to detect IUGR. However, we lack evidence for its clinical effectiveness and cost-effectiveness and information on ethical considerations of additional third trimester ultrasonography. This nationwide stepped wedge cluster-randomized trial examines the (cost-)effectiveness of routine third trimester ultrasonography in reducing severe adverse perinatal outcome through subsequent protocolized management.

Methods

For this trial, 15,000 women with a singleton pregnancy receiving care in 60 participating primary care midwifery practices will be included at 22 weeks of gestation. In the intervention (n = 7,500) and control group (n = 7,500) fetal growth will be monitored by serial fundal height assessments. All practices will start offering the control condition (ultrasonography based on medical indication). Every three months, 20 practices will be randomized to the intervention condition, i.e. apart from ultrasonography if indicated, two routine ultrasound examinations will be performed (at 28–30 weeks and 34–36 weeks). If IUGR is suspected, both groups will receive subsequent clinical management as described in the IRIS study protocol that will be developed before the start of the trial.

The primary dichotomous clinical composite outcome is ‘severe adverse perinatal outcome’ up to 7 days after birth, including: perinatal death; Apgar score <4 at 5 minutes after birth; impaired consciousness; need for assisted ventilation for more than 24 h; asphyxia; septicemia; meningitis; bronchopulmonary dysplasia; intraventricular hemorrhage; cystic periventricular leukomalacia; neonatal seizures or necrotizing enterocolitis. For the economic evaluation, costs will be measured from a societal perspective. Quality of life will be measured using the EQ-5D-5 L to enable calculation of QALYs. Cost-effectiveness and cost-utility analyses will be performed. In a qualitative sub-study (using diary notes from 32 women for 9 months, at least 10 individual interviews and 2 focus group studies) we will explore ethical considerations of additional ultrasonography and how to deal with them.

Discussion

The results of this trial will assist healthcare providers and policymakers in making an evidence-based decision about whether or not introducing routine third trimester ultrasonography.

Prenatal ultrasound screening: false positive soft markers may alter maternal representations and mother-infant interaction

BACKGROUND

In up to 5% of pregnancies, ultrasound screening detects a "soft marker" (SM) that places the foetus at risk for a severe abnormality. In most cases, prenatal diagnostic work-up rules out a severe defect. We aimed to study the effects of false positive SM on maternal emotional status, maternal representations of the infant, and mother-infant interaction.

METHODOLOGY AND PRINCIPAL FINDINGS

Utilizing an extreme-case prospective case control design, we selected from a group of 244 women undergoing ultrasound, 19 pregnant women whose foetus had a positive SM screening and a reassuring diagnostic work up, and 19 controls without SM matched for age and education. In the third trimester of pregnancy, within one week after delivery, and 2 months postpartum, we assessed anxiety, depression, and maternal representations. Mother-infant interactions were videotaped during feeding within one week after delivery and again at 2 months postpartum and coded blindly using the Coding Interactive Behavior (CIB) scales. Anxiety and depression scores were significantly higher at all assessment points in the SM group. Maternal representations were also different between SM and control groups at all study time. Perturbations to early mother-infant interactions were observed in the SM group. These dyads showed greater dysregulation, lower maternal sensitivity, higher maternal intrusive behaviour and higher infant avoidance. Multivariate analysis showed that maternal representation and depression at third trimester predicted mother-infant interaction.

CONCLUSION

False positive ultrasound screenings for SM are not benign and negatively affect the developing maternal-infant attachment. Medical efforts should be directed to minimize as much as possible such false diagnoses, and to limit their psychological adverse consequences.

Sonographers' Complex Communication during the Obstetric Sonogram Exam: An Interview Study

A study of the oral communication experiences and training of obstetric sonographers can provide insight into the complex expectations these medical professionals face as they complete their technical tasks and communicate with patients. Unlike other diagnostic medical professionals, obstetric sonographers are expected to provide detailed information to patients during the exam, a practice not typically found in the work of other types of medical diagnostic professionals. This study presents the results of interviews with 23 obstetric sonographers who described their communication experiences and their views on sonographer training in communication. Results suggest that sonographers experience complex communication challenges in the workplace that are not typically addressed in their education, nor are they officially recognized in the official discourse of their profession.

First-trimester screening: dealing with the fall-out

The articles collected together in this issue describe first-trimester screening for a variety of complications. With the advance of both technology and research, early pregnancy screening is becoming ever more sophisticated and complex. While there are clear benefits to most women receiving early reassurance that their baby is developing as expected, there is no evidence to suggest that an earlier prenatal diagnosis has less long-term emotional impact than at later gestations. The poignancy of ultrasound images for many parents means that it can be especially difficult to manage the anxiety when an ultrasound marker is highlighted as potential cause for concern. They can then face a journey of anxiety-laden uncertainty, which can extend through much of the pregnancy, and even beyond. Professionals involved in screening need to recognise and acknowledge such adverse side-effects and develop the skills necessary to help parents understand and cope with the uncertainties inherent in the process.

Did I really want to know this? Pregnant women's reaction to detection of a soft marker during ultrasound screening

OBJECTIVE

To investigate women's expectations of routine ultrasound and experiences when soft markers were discovered: what the disclosure meant, how it affected them, how they experienced the information given and why they did or did not choose amniocentesis.

DESIGN

Semi-structured, in-depth interviews were conducted with 11 women 25-30 weeks into the pregnancy, 7-13 weeks after the discovery of a soft marker.

FINDINGS

Women lacked knowledge about the potential of the scan and detection of soft markers created strong emotional reactions that women thought could have been alleviated by prior information about potential findings. Information in connection with the scan was perceived as insufficient. Decision about amniocentesis was affected by attitudes to disability, anxiety about fetal loss due to the procedure, need for certainty by a diagnostic test, and partner's opinion.

CONCLUSIONS

Women were shocked by the unexpected and sometimes unwanted information on elevated risk for a chromosomal aberration for which they lacked any preparation. Because this event often has long-lasting effects on the pregnancy, models of information that are efficient in promoting informed decisions are imperative.

PRACTICE IMPLICATIONS

Both women and their partners need relevant information before and in connection with ultrasound scan to be able to make informed choices.

Parental level of anxiety, sense of coherence and state of mind when choroid plexus cysts have been identified at a routine ultrasound examination in the second trimester of pregnancy: a case control study

The aim of the study was to compare parents' experience of a routine ultrasound examination in the second trimester, when a choroid plexus cyst/cysts (CPC) were found (Study group; n = 22), with matched controls where no fetal deviations were identified (Control group, n = 66). All the parents had participated in a larger cohort study. The instruments used for measuring anxiety were STAI-state/trait, sense of coherence (SOC) and Parents' Expectations, Experiences, Reactions to an Ultrasound examination during pregnancy (PEER-U, State of Mind Index). Regarding the SOC and STAI-state/trait no significant differences were found between the cases and controls or within the respective group before and after the ultrasound examination. The cases had an increase in anxiety (more anxious) as measured by the instrument PEER-U after the examination, while the controls showed a significant better level of State of Mind Index (less anxious) after the examination, compared to before. Therefore PEER-U can be a more reliable instrument when studying state of mind (anxiety) in connection with ultrasound examinations, and as it is specific for this situation it does not appear to be time dependent.

Information for better or for worse: interviews with parents when their foetus was found to have choroid plexus cysts at a routine second trimester ultrasound

The aim of the study was to gain a theoretical understanding of parents' experiences and handling of the situation, when their foetus was diagnosed as having choroid plexus cysts, at a routine second trimester ultrasound examination. Nine couples and one mother were interviewed using one open question. Analysis method was Grounded Theory. The main concern was anxiety and the core category became need for knowledge. The other categories were frightening and confusing, judging risk and making a choice and comforting. The parents felt information during the ultrasound examination was insufficient. The time delay between the diagnosis and the doctor's appointment was also often criticized. Most of the parents in this study wanted to know what can be diagnosed by ultrasound, even if there is a small risk that the child will have a malformation or chromosome abnormality. However, when the diagnosis is made, they need adequate information, otherwise unnecessary anxiety arises. By giving sufficient information without days of delay, anxiety can hopefully be minimized. Some written information was also requested. It is of utmost importance that the staff use the same terminology and the correct name of the soft marker to the parents.

Towards understanding the concept of risk for pregnant women: some nursing and midwifery implications

AIMS AND OBJECTIVES

This paper aims to explore the concept of risk in pregnancy.

BACKGROUND

Notions of risk and 'not knowing' have always surrounded pregnant women, although in the last two decades trends of increased consumer confidence and midwifery activism have together promoted a greater appreciation of pregnancy as a normal life event. At the same time, advances in pregnancy-related technologies have contributed new levels of concern related to an increasing ability to detect minor abnormalities by ultrasound. This, in turn, causes a concordant rise in the number of women referred to high-risk pregnancy care to monitor suspect findings. Overall, it seems likely that this increasing emphasis on abnormality detection and risk may have serious implications for women.

DESIGN

Concept analysis.

METHOD

In this paper, I undertake an exploration of the concept of risk as understood by health professionals and pregnant women. Then, using Deborah Lupton's understanding of a 'discourse of risk', I discuss the ways pregnant women both contribute to and are enmeshed in, this discourse. In the final section, I consider how nurses act informally to shield vulnerable women.

CONCLUSIONS

Health professionals and pregnant women understand risk differently. Women employ a subjective appraisal of risk, measuring it against their personal values and prior experience, while health professionals evaluate risk in an objective manner.

RELEVANCE TO CLINICAL PRACTICE

As increasing numbers of women are referred to 'at risk' care, it is important that health professionals understand and respond to maternal understandings of risk. Nurses and midwives particularly, have a role to play in assisting women to make sense of risk calculations. In this way, they can act to ameliorate the growing concept of risk for pregnant women.

Exploring general practitioners' experience of informing women about prenatal screening tests for foetal abnormalities: a qualitative focus group study

Background

Recent developments have made screening tests for foetal abnormalities available earlier in pregnancy and women have a range of testing options accessible to them. It is now recommended that all women, regardless of their age, are provided with information on prenatal screening tests. General Practitioners (GPs) are often the first health professionals a woman consults in pregnancy. As such, GPs are well positioned to inform women of the increasing range of prenatal screening tests available. The aim of this study was to explore GPs experience of informing women of prenatal genetic screening tests for foetal abnormality.

Methods

A qualitative study consisting of four focus groups was conducted in metropolitan and rural Victoria, Australia. A discussion guide was used and the audio-taped transcripts were independently coded by two researchers using thematic analysis. Multiple coders and analysts and informant feedback were employed to reduce the potential for researcher bias and increase the validity of the findings.

Results

Six themes were identified and classified as 'intrinsic' if they occurred within the context of the consultation or 'extrinsic' if they consisted of elements that impacted on the GP beyond the scope of the consultation. The three intrinsic themes were the way GPs explained the limitations of screening, the extent to which GPs provided information selectively and the time pressures at play. The three extrinsic factors were GPs' attitudes and values towards screening, the conflict they experienced in offering screening information and the sense of powerlessness within the screening test process and the health care system generally. Extrinsic themes reveal GPs' attitudes and values to screening and to disability, as well as raising questions about the fundamental premise of testing.

Conclusion

The increasing availability and utilisation of screening tests, in particular first trimester tests, has expanded GPs' role in facilitating women's informed decision-making. Recognition of the importance of providing this complex information warrants longer consultations to respond to the time pressures that GPs experience. Understanding the intrinsic and extrinsic factors that impact on GPs may serve to shape educational resources to be more appropriate, relevant and supportive.

Anxiety and prenatal testing: do women with soft ultrasound findings have increased anxiety compared to women with other indications for testing?

OBJECTIVE

To determine whether there is a difference in anxiety levels in women referred for soft ultrasound findings, AMA, and abnormal serum marker screens, all of whom have a similar risk for chromosome abnormalities, in order to provide an understanding of patients' anxiety, which may enhance the genetic counseling process.

METHODS

Two self-administered questionnaires were completed after the genetic counseling session. Participants were recruited from multiple prenatal clinics throughout Houston, Texas. The State-Trait Anxiety Inventory Form Y was used to measure anxiety in study participants. Both state and trait anxiety were assessed. Differences between groups were examined using one-way analysis of variance, crosstabulation, chi-square, and Tukey multiple comparisons analysis. A p-value of < 0.05 was considered significant.

RESULTS

Two hundred fifteen women participated in the study: 124 AMA, 55 abnormal maternal serum screens, and 36 soft ultrasound findings. Our findings revealed that women with soft ultrasound findings and abnormal maternal serum screens had significantly higher state anxiety than women who are AMA. State anxiety in women with soft ultrasound findings was not significantly different from women with abnormal maternal serum screens. No significant difference was found between the three groups for trait anxiety. Perceived risk, decision to undergo amniocentesis, education level, and income were factors that significantly affected the women's anxiety scores. However, none of these factors proved to be successful indicators of state or trait anxiety.

CONCLUSION

A woman's referral indication is associated with different levels of anxiety as compared to the actual numerical risk for chromosome abnormalities presented during a genetic counseling session.

Discovery of soft markers on fetal ultrasound: maternal implications

OBJECTIVE

to explore women's experiences of referral to tertiary care on the basis of uncertain ultrasound findings.

DESIGN

a qualitative method using Rice and Ezzy's thematic analysis approach. Data were gathered through two in-depth interviews over a six to eight-month period.

PARTICIPANTS

a total of 20 interviews were conducted among pregnant women, purposively recruited at a tertiary facility. Inclusion criteria were based on detection of an isolated soft marker in an otherwise normal pregnancy.

DATA ANALYSIS

interview data were transcribed and data were subjected to thematic analysis.

FINDINGS

mothers journeyed through a temporal sequence of adjustment following referral to specialist services. Four distinct phases were identified: realisation; making sense of events; anxious waiting; and having no clear resolution.

CONCLUSION

trends of increasing prenatal surveillance together with advancing technology make this study timely and of global interest. Findings suggest that women identified as 'at risk' before being discharged uneventfully may be prone to attachment issues and a host of other difficulties. The complexities inherent in this experience should be of interest to a broad range of health professionals. An appreciation of this experience may assist midwives and other health professionals to provide more meaningful maternal support to women identified as 'at risk'.

Management options for echogenic intracardiac focus and choroid plexus cysts: A review including Australian Association of Obstetrical and Gynaecological Ultrasonologists consensus statement

Echogenic intracardiac focus and choroid plexus cysts are common findings at the midtrimester ultrasound. These findings have been linked with an increased risk of Down syndrome and trisomy 18. Most fetuses with these findings will, however, not have chromosomal abnormalities, especially when these findings are isolated. Patients experience considerable anxiety when informed of these findings and require extensive counselling in order to minimize anxiety not only about aneuploidy but also about the structure and development of the heart and brain. Although early studies showed an association with aneuploidies, several recent studies have cast doubt on this association. Many of the early studies were carried out in high-risk populations or in populations that had not had the benefit of other screening tests. Many Australian and New Zealand patients will access screening tests designed to detect these aneuploidies before presenting for a midtrimester ultrasound. Patients who have been screened by nuchal translucency, maternal serum screening or some combination of the two will already have had most cases of Down syndrome and trisomy 18 detected, and any soft marker found will almost certainly be a false positive. It is time to rethink the management of these markers. Recent evidence indicates that if these markers are found in isolation in an otherwise low-risk pregnancy, then there is minimal or no increase in the risk of Down syndrome or trisomy 18: these markers should be considered normal variants. The Australian Association of Obstetrical and Gynaecological Ultrasonologists consensus statement on these markers is included.

First Mothering Over 35 Years: Questioning the Association of Maternal Age and Pregnancy Risk

Women having a first baby at 35+ years are commonly considered to be "at risk" for pregnancy complications. This understanding appears to be based primarily on age, and curerntly many healthy women are included in this category. There is clear evidence to suggest that, for these women, being considered "at risk" is anxiety provoking. In this Australian qualitative study of first mothering over 35 years, we found four risk-related themes, "realizing I was at risk," "hoping for reassurance," "dealing with uncertainty," and "getting through it/negotiating risk." We concluded that successful adjustment to motherhood related principally to participants negotiating risk and also to the infant growing and becoming more responsive. Attitudes of health professionals were found to contribute to rather than ameliorate participant dilemmas. Understanding how healthy women over 35 years engage with and negotiate notions of risk may assist health professionals in the provision of more meaningful maternal support for this growing group of women.

Detection of malformations in chromosomally normal fetuses by routine ultrasound at 12 or 18 weeks of gestation-a randomised controlled trial in 39,572 pregnancies

OBJECTIVE

To compare the antenatal detection rate of malformations in chromosomally normal fetuses between a strategy of offering one routine ultrasound examination at 12 gestational weeks (gws) and a strategy of offering one routine examination at 18 gws.

DESIGN

Randomised controlled trial.

SETTING

Multicentre trial including eight hospitals.

POPULATION

A total of 39,572 unselected pregnant women.

METHODS

Women were randomised either to one routine ultrasound scan at 12 (12-14) gws including nuchal translucency (NT) measurement or to one routine scan at 18 (15-22) gws. Anomaly screening was performed in both groups following a check-list. A repeat scan was offered in the 12-week scan group if the fetal anatomy could not be adequately seen at 12-14 gws or if NT was >or=3.5 mm in a fetus with normal or unknown chromosomes.

MAIN OUTCOME MEASURES

Antenatal detection rate of malformed fetuses.

RESULTS

The antenatal detection rate of fetuses with a major malformation was 38% (66/176) in the 12-week scan group and 47% (72/152) in the 18-week scan group (P= 0.06). The corresponding figures for detection at <22 gws were 30% (53/176) and 40% (61/152) (P= 0.07). In the 12-week scan group, 69% of fetuses with a lethal anomaly were detected at a scan at 12-14 gws.

CONCLUSIONS

None of the two strategies for prenatal diagnosis is clearly superior to the other. The 12-week strategy has the advantage that most lethal malformations will be detected at <15 gws, enabling earlier pregnancy termination. The 18-week strategy seems to be associated with a slightly higher detection rate of major malformations, although the difference was not statistically significant.

Women's response to fetal choroid plexus cysts detected by prenatal ultrasound

OBJECTIVES

To determine maternal responses to detection of a minor structural variant, the choroid plexus cyst (CPC), in their fetus on prenatal ultrasound.

STUDY DESIGN

We interviewed 34 pregnant women with an isolated CPC detected on mid-pregnancy ultrasound about their objective experience at diagnosis, emotional response and subsequent reactions. Audiotaped, transcribed responses were evaluated by two independent raters and analyzed qualitatively and quantitatively.

RESULTS

All women reported negative emotional responses including shock, distress, fear and decreased attachment, despite counseling by 82% of providers that the CPC was probably benign. Three women underwent amniocentesis purely for reassurance after CPC detection. Most (79%) sought information beyond what their physician provided, frequently on the internet. One half of women reported that intense negative responses were temporary. However, weeks after diagnosis, 62% continued to believe that the CPC presented some danger to their baby.

CONCLUSIONS

Detection of CPC prenatally can evoke profound, negative maternal emotional responses despite accurate provider counseling. Practitioners should consider these responses when counseling parents about these and other structural variants of unclear functional significance.

False-positive rate in prenatal diagnosis of surgical anomalies

BACKGROUND/PURPOSE

Technical refinements and increasingly sophisticated equipment have led to higher sensitivity in prenatal diagnosis of congenital malformations; however, such progress may be accompanied by decreased specificity. The aim of this study is to evaluate evolution of prenatal diagnosis from the first sonographic suspicion of fetal anomaly until after delivery (diagnosis confirmed, resolution before birth, healthy baby, or affected with different disorder) to document rate of false-positive (FP) results.

METHODS

Retrospective review of prenatal ultrasound examinations performed at our institution between 2000 and 2002 was conducted. The series includes pregnancies referred to our department after detection of thoracic and abdominal anomalies at routine obstetrical sonography and with a follow-up comprising at least the first 6 months of life. Urologic malformations were excluded. Those fetuses who proved healthy at birth were considered FP results.

RESULTS

One hundred fifty-seven fetuses/neonates underwent complete follow-up. Prenatal diagnosis of esophageal atresia resulted in 3 (27%) of 11 FPs. Finding of dilated bowel, isolated or associated with hyperechogenicity or ascites, was not predictive of small bowel obstruction in 7 (41%) of 17 fetuses. No FPs were found with regard to abdominal wall defects (8 gastroschisis and 26 omphaloceles, all confirmed at birth). Concerning thoracic malformations, no FPs were seen among the 28 cases of congenital diaphragmatic hernia, whereas diagnosis of lung malformation presented a specificity of 97% (1/28 FP). Ovarian cysts accounted for an FP rate of 17% (4/23 FPs). Overall, a percentage of FP of 12% (6/50) was seen in 2000, of 11% (5/44) in 2001, and 9% (6/63) in 2002, with no statistically significant difference.

CONCLUSIONS

Because of the high FP rate regarding some particular anomalies, unnecessary psychological burden to prospective parents may ensue. This issue should be dealt with in future prospective studies.

Pregnant women's responses to information about an increased risk of carrying a baby with Down syndrome

BACKGROUND

Fetal screening for Down syndrome by an ultrasound examination, including measurement of fetal nuchal translucency, at 12 to14 weeks' gestation is presently being evaluated in a Swedish randomized controlled trial. Women at high risk were offered an amniocentesis to obtain a definite diagnosis. The aim of this study was to explore women's reactions and responses to information about being at high risk after the scan, with a special focus on reactions to a false positive test.

METHOD

Interviews were conducted with 24 women within 1 week after the scan, in midpregnancy, and 2 months after the birth. The interviews were analyzed qualitatively. Down syndrome was confirmed in 4 women, who chose to terminate the pregnancy. The remaining 20 women had a false positive test.

RESULTS

For the majority, the risk information caused strong reactions of anxiety and worries about the future. A typical way for women to cope was to "withhold" the pregnancy, to take a "timeout," and try to live as if they were not pregnant any longer. Some weeks later, when the women received normal results from the chromosome analysis, they resumed being pregnant. Six women ages more than 35 years who had a risk score lower than their age-related risk did not express similarly strong reactions. Two months after the birth of a healthy baby, most stated they would undergo the same procedure in a subsequent pregnancy. One woman still suffered from the experience when interviewed at 2 months after the birth, and another said she regretted participating in the fetal screening program.

CONCLUSIONS

A false positive test of fetal screening for Down syndrome by ultrasound examination may cause strong reactions of anxiety and even rejection of the pregnancy. The prevalence of such reactions and possible long-term effects need further investigation.

Maternal anxiety and ultrasound markers for aneuploidy in a multiethnic population

OBJECTIVE

Discussion of isolated ultrasound (US) markers for fetal aneuploidy can provoke significant patient anxiety. The objective of this study is to quantify maternal anxiety associated with the detection of these markers.

METHODS

All patients undergoing routine second-trimester US examination for fetal anatomical survey over a one-year period were administered the State-Trait Anxiety Inventory (STAI) for Adults before and after the procedure. Women with isolated fetal markers for aneuploidy were notified of the findings but discouraged from pursuing amniocentesis. Rates of normal US examination, aneuploidy markers, anomalies, amniocentesis, and pregnancy outcomes were assessed across the ethnic groups. Pre- and post-ultrasound STAI surveys were scored and standardized with previously established norms. Student t-tests, Chi-square, and analysis of variance (ANOVA) were used where appropriate.

RESULTS

Among the 798 patients tested, 57% were Hispanic, 30% were Asian, 6% were Black, and 7% were White. Maternal anxiety level was decreased in women after a normal US. The anxiety level increased with aneuploidy markers and was the highest with anomalies. Aneuploidy markers were more common among Hispanic and Asian fetuses, without any associated aneuploidy. Women with isolated aneuploidy markers underwent amniocentesis as often as women with advanced maternal age.

CONCLUSION

The detection and communication of isolated aneuploidy markers is associated with increased maternal anxiety and unnecessary amniocentesis.

Developmental outcome of children who had choroid plexus cysts detected prenatally

OBJECTIVE

The purpose of this study was to evaluate cognitive, motor, language and adaptive behavior development in children who had isolated choroid plexus cysts (CPC) detected prenatally.

METHODS

A retrospective double cohort design and standardized psychometric measures were used to compare the development of children who had isolated CPCs identified prenatally with a control group of children who had normal prenatal ultrasounds.

RESULTS

Our study cohort (n = 37) had a mean age of 3.88 years (SD = 0.83) and the control cohort (n = 48) had a mean age of 4.62 years (SD = 1.03). The age difference between our cohorts was significant. There were no differences between cohorts in socioeconomic status, sex, birth weight or gestational age. Cognitive data showed no clinically significant difference in Full Scale IQ using the WISC-III or WPPSI-R (CPC = 113.97, control = 116.69). Scores on standardized measures of motor and adaptive functioning also did not show any significant group differences. Children with CPCs did score significantly lower than controls on some of the measures of verbal functioning; however, this difference was not associated with clinically significant delays.

CONCLUSION

We conclude that the presence of isolated CPCs on midtrimester ultrasound are unlikely to be associated with any significant neurocognitive delays in early childhood.

Echogenic intracardiac focus: potential for misdiagnosis

OBJECTIVE

To assess the potential rate of specular reflectors within the fetal heart producing reflections of sufficient amplitude to be mistaken for echogenic intracardiac foci.

METHODS

Between July 1999 and December 2000, 200 patients were randomly selected from the University of California, San Francisco, perinatal database who met the following criteria: (1) had singleton pregnancy, (2) delivered at University of California, San Francisco, and (3) had obstetric sonography at University of California, San Francisco, between 18 and 22 weeks' gestation. Bright focal reflections within the heart were judged to be either "true" or "false" echogenic intracardiac foci.

RESULTS

In this population of patients who underwent routine obstetric sonography at a tertiary care hospital, the rate of true echogenic intracardiac focus cases was 11 per 200 (5.5%). The rate of false echogenic intracardiac focus cases was 34 per 200 (17%). The most common locations for identification of a spurious echogenic intracardiac focus were the endocardial cushion, the moderator band, and the tricuspid valve annulus.

CONCLUSIONS

A specular reflection from the moderator band was judged the false echogenic intracardiac focus most likely to fool examiners. The rate of specular reflection from the moderator band was 11 per 200 (5.5%). Because it is possible to generate a specular reflection from an interface in the fetal heart in virtually any patient, it is important to exercise caution before diagnosing an echogenic intracardiac focus.
