Ethical considerations in prenatal testing: Genomic testing and medical uncertainty

Exploring prenatal testing preferences among US pregnant individuals: A discrete choice experiment

Although there are numerous benefits to diagnostic prenatal testing, such as fetal exome sequencing, there are also consequences, including the possibility of receiving variants of uncertain significance or identifying secondary findings. In this study, we utilized a survey-based discrete choice experiment to elicit the preferences of pregnant people in Northern California for hypothetical prenatal genomic tests. Pregnant individuals were invited to complete the survey through advertisements on social media. Five test attributes were studied: likelihood of getting a result, time taken to receive results, who explains results, reporting of uncertain results, and reporting of secondary findings. The survey also gathered information about the participants' demographics, current and past pregnancies, and tolerance of uncertainty using the IUS-12 scale. Participants were eligible if they were female, currently 24 or more weeks pregnant, and able to read/write enough English or Spanish to complete an online survey. Overall, participants (n = 56) preferred the option of having a prenatal test over not having a prenatal test (p < 0.01) and had substantially higher preferences for tests with the highest likelihood of getting a result (p < 0.01). There were also positive preferences for tests that reported secondary findings (p = 0.01) and those where results were returned by a genetic specialist (vs. their prenatal provider) (p = 0.04). These findings can be used to guide conversations between pregnant individuals and genetics specialists, such as genetic counselors, as they weigh the pros and cons of diagnostic prenatal testing options.

'Something that helped the whole picture': Experiences of parents offered rapid prenatal exome sequencing in routine clinical care in the English National Health Service

OBJECTIVES

In October 2020, rapid prenatal exome sequencing (pES) was introduced into routine National Health Service (NHS) care in England. This study aimed to explore parent experiences and their information and support needs from the perspective of parents offered pES and of health professionals involved in its delivery.

METHODS

In this qualitative study, semi-structured interviews were conducted with 42 women and 6 male partners and 63 fetal medicine and genetic health professionals. Interviews were transcribed verbatim and analysed using thematic analysis.

RESULTS

Overall views about pES were positive and parents were grateful to be offered the test. Highlighted benefits of pES included the value of the additional information for pregnancy management and planning for future pregnancies. An anxious wait for results was common, often associated with the need to make decisions near to 24 weeks in pregnancy when there are legal restrictions for late termination. Descriptions of dealing with uncertainty were also common, even when results had been returned. Many parents described pES results as informing decision-making around whether or not to terminate pregnancy. Some professionals were concerned that a non-informative result could be overly reassuring and highlighted that careful counselling was needed to ensure parents have a good understanding of what the result means for their pregnancy. Emotional support from professionals was valued; however, some parents felt that post-test support was lacking.

CONCLUSION

Parents and professionals welcomed the introduction of pES. Results inform parents' decision-making around the termination of pregnancy. When there are no diagnostic findings or uncertain findings from pES, personalised counselling that considers scans and other tests are crucial. Directing parents to reliable online sources of information and providing emotional support throughout could improve their experiences of care.

Prenatal diagnosis by trio exome sequencing in fetuses with ultrasound anomalies: A powerful diagnostic tool

Introduction: Prenatal ultrasound (US) anomalies are detected in around 5%-10% of pregnancies. In prenatal diagnosis, exome sequencing (ES) diagnostic yield ranges from 6% to 80% depending on the inclusion criteria. We describe the first French national multicenter pilot study aiming to implement ES in prenatal diagnosis following the detection of anomalies on US. Patients and methods: We prospectively performed prenatal trio-ES in 150 fetuses with at least two US anomalies or one US anomaly known to be frequently linked to a genetic disorder. Trio-ES was only performed if the results could influence pregnancy management. Chromosomal microarray (CMA) was performed before or in parallel. Results: A causal diagnosis was identified in 52/150 fetuses (34%) with a median time to diagnosis of 28 days, which rose to 56/150 fetuses (37%) after additional investigation. Sporadic occurrences were identified in 34/56 (60%) fetuses and unfavorable vital and/or neurodevelopmental prognosis was made in 13/56 (24%) fetuses. The overall diagnostic yield was 41% (37/89) with first-line trio-ES versus 31% (19/61) after normal CMA. Trio-ES and CMA were systematically concordant for identification of pathogenic CNV. Conclusion: Trio-ES provided a substantial prenatal diagnostic yield, similar to postnatal diagnosis with a median turnaround of approximately 1 month, supporting its routine implementation during the detection of prenatal US anomalies.

Parental Hopes and Understandings of the Value of Prenatal Diagnostic Genomic Sequencing: A Qualitative Analysis

Objective: To provide qualitative empirical data on parental expectations of diagnostic prenatal genomic sequencing and the value of the results to families.

Methods: We interviewed 15 families—mothers and/or fathers—who had had prenatal genomic sequencing about their expectations and their respective evaluations of the benefits of genomic sequencing.

Results: Families’ hopes for genetic sequencing clustered around three themes: hoping to identify the cause of the fetal anomaly in a terminated pregnancy; hopes for guidance as to the likely outcome of current pregnancy; and hopes for information to support future family planning. In addition, hopes were discussed in terms of the potential for results to be beneficial in acquiring greater knowledge, while at the same time recognizing that new knowledge may raise more questions. Assessment of the value of sequencing largely mirrored these expectations when positive results seen. Negative results can also be seen as valuable in ruling out a genetic cause and in providing certainty that families had done everything that they could to know about the cause of fetal demise.

Conclusion: It would appear that with guidance from genetic counsellors, families were largely able to navigate the many uncertainties of prenatal genomic sequencing and thus see themselves as benefitting from sequencing. However, support structures are essential to guide them through their expectations and interpretations of results to minimize possible harms. Engaging in the process of genomic sequencing was seen as beneficial in of itself to families who would otherwise be left without any options to seek diagnostic answers.

“Let’s Just Wait Until She’s Born”: Temporal Factors That Shape Decision-Making for Prenatal Genomic Sequencing Amongst Families Underrepresented in Genomic Research

Genomic sequencing has been increasingly utilized for prenatal diagnosis in recent years and this trend is likely to continue. However, decision-making for parents in the prenatal period is particularly fraught, and prenatal sequencing would significantly expand the complexity of managing health risk information, reproductive options, and healthcare access. This qualitative study investigates decision-making processes amongst parents who enrolled or declined to enroll in the prenatal arm of the California-based Program in Prenatal and Pediatric Genome Sequencing (P3EGS), a study in the Clinical Sequencing Evidence-Generating Research (CSER) consortium that offered whole exome sequencing for fetal anomalies with a focus on underrepresented groups in genomic research. Drawing on the views of 18 prenatal families who agreed to be interviewed after enrolling (n = 15) or declining to enroll (n = 3) in P3EGS, we observed that the timing of sequencing, coupled with unique considerations around experiences of time during pregnancy and prenatal testing, intersect with structural supports beyond the clinic to produce preferences for and against prenatal sequencing and to contain the threat of unwelcome, uncertain knowledge. Particularly for those without structural supports, finding out consequential information may be more palatable after the birth, when the first stage of the uncertain future has been revealed. Future research should examine the role of temporality in decision-making around prenatal genomic sequencing across diverse population cohorts, in order to observe more precisely the role that structural barriers play in patient preferences.

Assessing women’s preferences towards tests that may reveal uncertain results from prenatal genomic testing: Development of attributes for a discrete choice experiment, using a mixed-methods design

Prenatal DNA tests, such as chromosomal microarray analysis or exome sequencing, increase the likelihood of receiving a diagnosis when fetal structural anomalies are identified. However, some parents will receive uncertain results such as variants of uncertain significance and secondary findings. We aimed to develop a set of attributes and associated levels for a discrete-choice experiment (DCE) that will examine parents’ preferences for tests that may reveal uncertain test results. A two phase mixed-methods approach was used to develop attributes for the DCE. In Phase 1, a “long list” of candidate attributes were identified via two approaches: 1) a systematic review of the literature around parental experiences of uncertainty following prenatal testing; 2) 16 semi-structured interviews with parents who had experienced uncertainty during pregnancy and 25 health professionals who return uncertain prenatal results. In Phase 2, a quantitative scoring exercise with parents prioritised the candidate attributes. Clinically appropriate levels for each attribute were then developed. A final set of five attributes and levels were identified: likelihood of getting a result, reporting of variants of uncertain significance, reporting of secondary findings, time taken to receive results, and who tells you about your result. These attributes will be used in an international DCE study to investigate preferences and differences across countries. This research will inform best practice for professionals supporting parents to manage uncertainty in the prenatal setting.

Fetal information as shared information: using NIPT to test for adult-onset conditions

The possibilities of non-invasive prenatal testing (NIPT) are expanding, and the use of NIPT for adult-onset conditions may become widely available in the near future. If parents use NIPT to test for these conditions, and the pregnancy is continued, they will have information about the child's genetic predisposition from birth. In this paper, we argue that prospective parents should be able to access NIPT for an adult-onset condition, even when they have no intention to terminate the pregnancy. We begin by outlining the arguments against testing in such a situation, which generally apply the same considerations that apply in the predictive testing of a minor to the fetus in utero. We then contend, firstly, that there are important practical considerations that support availability of testing for prospective parents regardless of their stated intentions. Secondly, we object to the ethical equation of a fetus in utero with a minor. We base our analysis on a view of pregnancy that conceptualises the fetus as a part of the gestational parent, as opposed to the more common 'container' model of pregnancy. We suggest that fetal information is best conceptualised as shared information between the gestational parent and future child. Thus, it should be approached in similar ways as other kinds of shared information (such as genetic information with implications for family members), where a person has a claim over their own information, but should be encouraged to consider the interests of other relevant parties.

Parental experiences of rapid exome sequencing in cases with major ultrasound anomalies during pregnancy

BACKGROUND

Adding rapid exome sequencing (rES) to conventional genetic tests improves the diagnostic yield of pregnancies showing ultrasound abnormalities but also carries a higher chance of unsolicited findings. We evaluated how rES, including pre- and post-test counseling, was experienced by parents investigating its impact on decision-making and experienced levels of anxiety.

METHODS

A mixed-methods approach was adopted. Participating couples (n = 46) were asked to fill in two surveys (pre-test and post-test counseling) and 11 couples were approached for an additional interview.

RESULTS

All couples accepted the rES test-offer with the most important reason for testing emphasizing their hope of finding an underlying diagnosis that would aid decision-making. The actual impact on decision-making was low, however, since most parents decided to terminate the pregnancy based on the major and multiple fetal ultrasound anomalies and did not wait for their rES results. Anxiety was elevated for most participants and decreased over time.

CONCLUSION

Major congenital anomalies detected on ultrasound seem to have more impact on prenatal parental decision-making and anxiety then the offer and results of rES. However, the impact of rES on reproductive decision-making and experienced anxiety requires further investigation, especially in pregnancies where less (severe) fetal anomalies are detected on ultrasound.

The fetus in the age of the genome

Due to a number of recent achievements, the field of prenatal medicine is now on the verge of a profound transformation into prenatal genomic medicine. This transformation is expected to not only substantially expand the spectrum of prenatal diagnostic and screening possibilities, but finally also to advance fetal care and the prenatal management of certain fetal diseases and malformations. It will come along with new and profound challenges for the normative framework and clinical care pathways in prenatal (and reproductive) medicine. To adequately address the potential ethically challenging aspects without discarding the obvious benefits, several agents are required to engage in different debates. The permissibility of the sequencing of the whole fetal exome or genome will have to be examined from a philosophical and legal point of view, in particular with regard to conflicts with potential rights of future children. A second requirement is a societal debate on the question of priority setting and justice in relation to prenatal genomic testing. Third, a professional-ethical debate and positioning on the goal of prenatal genomic testing and a consequential re-structuring of clinical care pathways seems to be important. In all these efforts, it might be helpful to envisage the unborn rather not as a fetus, not as a separate moral subject and a second "patient", but in its unique physical connection with the pregnant woman, and to accept the moral quandaries implicitly given in this situation.

Cytogenetic and molecular diagnostic testing associated with prenatal and postnatal birth defects

Genetic testing is beneficial for patients and providers when in search of answers to medical problems related to the prenatal or early postnatal period. It can help to identify the cause or confirm a diagnosis associated with developmental delay, intellectual disability, dysmorphic features, heart defects, multiple malformations, short stature, stillbirth, neonatal death, or fertility problems. Genetic testing can be used to rule out single‐gene or chromosome abnormalities. Different diagnostic cytogenetic and molecular genetic techniques are applied in clinical genetics laboratories, from conventional ones to the state of the art chromosomal microarrays and next‐generation sequencing. Each of the genetic techniques or methods has its strengths and limitations, however different methods complement each‐other in trying to identify the genetic variation(s) responsible for a medical condition, especially the ones related to birth defects.

Die Rechte zukünftiger Kinder im Kontext pränataler Diagnostik

Das Gendiagnostikgesetz (GenDG) verbietet seit 2010 die pränatale Diagnostik spätmanifestierender Erkrankungen (§ 15(2) GenDG). In seiner Begründung bezog sich der Gesetzgeber in Analogie zu internationalen Empfehlungen für den pädiatrischen Bereich vor allem auf das Recht des heranwachsenden Kindes bzw. des späteren Erwachsenen auf Nichtwissen. Mit diesem gesetzlichen Verbot hat Deutschland einen viel diskutierten Sonderweg in der Regulierung genetischer Pränataldiagnostik eingeschlagen. Seither jedoch hat sich nicht nur die Perspektive auf prädiktive Testungen im Kindesalter verändert. In zunehmendem Maße generieren auf das gesamte Genom abzielende Diagnostikangebote auch andere vorgeburtlich genetische Informationen, die – in ähnlicher Weise wie diejenigen zu spätmanifestierenden Erkrankungen eine potenzielle Gefahr für das Recht auf Nichtwissen der späteren Person darstellen. Es soll daher im Rahmen dieses Beitrages überprüft werden, inwiefern das deutsche Diagnostikverbot und dessen Bezug auf das Recht auf Nichtwissen des späteren Kindes eine tragfähige Basis zur Regulierung gendiagnostischer Untersuchungen in der Pränatalmedizin insgesamt darstellt bzw. zukünftig darstellen kann.

Untersucht wird der Argumentationsgang des Diagnostikverbotes im Hinblick auf spätmanifestierende Erkrankungen vor dem Hintergrund der Entwicklungen in der prädiktiven (genomischen) Diagnostik. Eine Analyse des normativen Begründungsrahmens zeigt, dass nach wie vor deutlicher Klärungsbedarf hinsichtlich der philosophisch-ethischen Fundierung wie auch hinsichtlich der Interpretation eines Rechts auf Nichtwissen eines (zukünftigen) Kindes im Kontext von genetischer Diagnostik besteht. Darüber hinaus müssen auch Interessen des (zukünftigen) Kindes an eventuell möglich werdender pränataler Behandlung oder Prävention von Erkrankungen in die Abwägung miteinbezogen werden.

Um zukünftigen Herausforderungen genomischer Pränataldiagnostik und -therapie begegnen zu können, müsste dringend geklärt werden, inwiefern Rechte zukünftiger Personen tatsächlich in der speziellen Situation der Schwangerschaft relevant sein können und mit welchen Pflichten diese für den Gesetzgeber, aber insbesondere auch für zukünftige Eltern und Ärzte einhergehen. Der Menschenrechtsdiskurs könnte hierfür eine tragfähige Basis und hilfreiche Strategien liefern.

The role of next-generation sequencing in the investigation of ultrasound-identified fetal structural anomalies

Fetal structural anomalies have an impact on fetal mortality and morbidity. Next-generation sequencing (NGS) may be incorporated into clinical pathways for investigation of paediatric morbidity but can also be used to delineate the prognosis of fetal anomalies. This paper reviews the role of NGS in the investigation of fetal malformations, the literature defining the clinical utility, the technique most commonly used and potential promise and challenges for implementation into clinical practice. Prospective case selection with informative pre-test counselling by multidisciplinary teams is imperative. Regulated laboratory sequencing, bioinformatic pathways with potential variant identification and conservative matching with the phenotype is important. TWEETABLE ABSTRACT: Prenatal exome sequencing in fetal structural anomalies yields diagnostic information in up to 20% of cases.

Prenatal Exome Sequencing: Background, Current Practice and Future Perspectives-A Systematic Review

The introduction of Next Generation Sequencing (NGS) technologies has exerted a significant impact on prenatal diagnosis. Prenatal Exome Sequencing (pES) is performed with increasing frequency in fetuses with structural anomalies and negative chromosomal analysis. The actual diagnostic value varies extensively, and the role of incidental/secondary or inconclusive findings and negative results has not been fully ascertained. We performed a systematic literature review to evaluate the diagnostic yield, as well as inconclusive and negative-result rates of pES. Papers were divided in two groups. The former includes fetuses presenting structural anomalies, regardless the involved organ; the latter focuses on specific class anomalies. Available findings on non-informative or negative results were gathered as well. In the first group, the weighted average diagnostic yield resulted 19%, and inconclusive finding rate 12%. In the second group, the percentages were extremely variable due to differences in sample sizes and inclusion criteria, which constitute major determinants of pES efficiency. Diagnostic pES availability and its application have a pivotal role in prenatal diagnosis, though more homogeneity in access criteria and a consensus on clinical management of controversial information management is envisageable to reach widespread use in the near future.

Psychological measures of patient's decision-making for prenatal genetic testing

OBJECTIVE

To use a questionnaire to determine the levels of maternal decision-related distress, clarity of the pros and cons, and certainty when considering prenatal genetic diagnostic testing; and to assess the relationship between these constructs and patient characteristics.

METHOD

Cross-sectional study. Voluntary, anonymous questionnaires distributed 2017-2019 to women referred for invasive prenatal genetic testing. Excluded: English or Spanish illiterate. Maternal characteristics were collected. Questions evaluated distress, decisional certainty, and decisional clarity on a 5-point Likert scale (range: 0 = low/uncertain/unclear to 4 = high/certain/clear). Analysis: non-parametric Kruskal-Wallis, correlation statistics, and ANOVA.

RESULTS

Forty-four female patients completed it. Most were married, white, Catholic, and multiparous. 58% had already made a testing decision. Patients expressed low distress levels (mean 1.18 ± 0.80) and expressed high decisional certainty (mean 3.28 ± 0.76) and clarity (mean 3.30 ± 0.99). Decisional certainty and clarity were positively correlated (r = 0.47, p < .01), whereas distress was negatively correlated with decisional certainty (r = -0.8136, p < .0005) and decisional clarity (r = -0.49, p = .007). No significant differences by religion or parity. Greater distress (p < .05) and less decisional clarity (p = .07) occurred between those still debating testing vs those who had decided.

CONCLUSIONS

Higher maternal distress scores were associated with lower decisional certainty and decisional clarity in women considering prenatal genetic testing.

Parental experiences of uncertainty following an abnormal fetal anomaly scan: Insights using Han's taxonomy of uncertainty

For a number of prospective parents, uncertainty during pregnancy starts when an anomaly is found during a routine fetal anomaly scan. This may be followed by numerous tests to determine the etiology and nature of the anomaly. In this study, we aimed to understand how prospective parents perceive and manage uncertainty after being confronted with a structural anomaly during their routine ultrasound. Han's taxonomy of uncertainty was used as a framework to identify and understand the different types of uncertainty experienced. Interviews were held in the UK (n = 8 women and n = 1 male partner) and in the Netherlands (n = 7 women) with participants who had experienced uncertainty in their pregnancy after a fetal scan. Data were analyzed using thematic analysis, and the uncertainties experienced by parents were mapped against the dimensions of the Han taxonomy (sources, issues, and locus). Participants' experience of uncertainty was relevant to all dimensions and subcategories of the Han taxonomy, showing its applicability in the prenatal setting. Sources of uncertainty included receiving probabilistic or ambiguous information about the anomaly, or information that was complex and challenging to understand. Issues of uncertainty included were those that were scientific—such as a probable diagnosis with no further information, personal—such as the emotional impact of uncertainty, and practical—such as limited information about medical procedures and practical aspects of care. Additionally, participants described what helped them to manage uncertainty. This included active coping strategies such as searching for information on the Internet, external coping resources such as seeking social support, and internal coping resources such as using positivity and hope. Several recommendations for the healthcare professional to minimize uncertainty and help the patient deal with uncertainty have been proposed based on these findings.

Couples experiences of receiving uncertain results following prenatal microarray or exome sequencing: A mixed-methods systematic review

Background

Tests in pregnancy such as chromosomal microarray analysis and exome sequencing are increasing diagnostic yield for fetal structural anomalies, but have greater potential to result in uncertain findings. This systematic review investigated the experiences of prospective parents about receiving uncertain results from these tests.

Methods

A systematic search of three electronic databases was conducted. Data extraction was performed for studies that met the eligibility and quality criteria. Results were synthesised following the principles of thematic analysis.

Results

Fourteen studies (10 qualitative, 4 quantitative) were included. Findings were grouped into three overarching themes. Sources of uncertainty included the testing procedure, the diagnosis and prognosis, and health professionals' own uncertainty. The clinical impact of the uncertainty included parents struggling to make clinical decisions with the information available, the emotional impact included decisional‐regret, shock, worry and feeling overwhelmed. To manage the uncertainty, parents sought support from healthcare professionals, friends, family, the internet and other parents as well as remaining hopeful.

Conclusions

Prospective parents experience a myriad of uncertainties in the prenatal setting, which must be handled sensitively. Future research should explore optimal ways of managing uncertainty to minimise harm. Recommendations are made for discussing uncertainty during pre‐ and post‐test counseling.

Noninvasive prenatal screening for patients with high body mass index: Evaluating the impact of a customized whole genome sequencing workflow on sensitivity and residual risk

Objective

Women with high body mass index (BMI) tend to have reduced fetal fraction (FF) during cell‐free DNA‐based noninvasive prenatal screening (NIPS), causing test failure rates up to 24.3% and prompting guidelines that recommend aneuploidy screening other than NIPS for patients with significant obesity. Because alternatives to NIPS are only preferable if they perform better, we compared the respective sensitivities at different BMI levels of traditional aneuploidy screening and a customized whole‐genome sequencing NIPS.

Method

The relationship between FF, aneuploidy, and BMI was quantified from 58 105 patients screened with a customized NIPS that does not fail samples because of low FF alone. Expected analytical sensitivity as a function of aneuploidy and BMI (eg, trisomy 18 sensitivity when BMI = 35) was determined by scaling the BMI‐ and aneuploidy‐specific FF distribution by the FF‐ and aneuploidy‐specific sensitivity calculated from empirically informed simulations.

Results

Across all classes of obesity and assuming zero FF‐related test failures, analytical sensitivity for the investigated NIPS exceeded that of traditional aneuploidy screening for trisomies 13, 18, and 21.

Conclusion

Relative to traditional aneuploidy screening, a customized NIPS with high accuracy at low FF and a low test‐failure rate is a superior screening option for women with high BMI.

What's already known about this topic?

Women with high body mass index (BMI) often receive a test failure on noninvasive prenatal screening (NIPS) because of low fetal fraction (FF).

The American College of Medical Genetics and Genomics recommends offering traditional aneuploidy screening to patients with “significant obesity.”

NIPS offerings differ in their efficacy at low FF.

What does this study add?

Irrespective of BMI and without FF‐based test failures, it is possible for a customized NIPS to provide all women with accurate prenatal screening.

From diagnostic yield to clinical impact: a pilot study on the implementation of prenatal exome sequencing in routine care

PURPOSE

Exome sequencing (ES) is an efficient tool to diagnose genetic disorders postnatally. Recent studies show that it may have a considerable diagnostic yield in fetuses with structural anomalies on ultrasound. We report on the clinical impact of the implementation of prenatal ES (pES) for ongoing pregnancies in routine care.

METHODS

We retrospectively analyzed the impact of pES on pregnancy outcome and pre- or perinatal management in the first 22 patients counseled for pES because of one or more structural anomalies on fetal ultrasound.

RESULTS

In two cases, a diagnosis was made by chromosomal microarray analysis after ES counseling. The remaining 20 cases were divided in three groups: (1) pES to aid parental decision making (n = 12), (2) pES in the context of late pregnancy termination requests (n = 5), and (3) pES to guide pre- or perinatal management (n = 3). pES had a clinical impact in 75% (9/12), 40% (2/5), and 100% (3/3) respectively, showing an overall clinical impact of pES of 70% (14/20).

CONCLUSION

We show that clinical implementation of pES is feasible and affects parental decision making or pre- and perinatal management supporting further implementation of ES in the prenatal setting.

Knowledge about Neonatal Screening among Postpartum Women and Complexity Level of Birthing Facilities

BACKGROUND

To ascertain the degree of knowledge of postpartum women about important aspects related to the neonatal screening process and whether differences of opinion exist between those who deliver in low-complexity versus high-complexity health facilities (low-risk versus high-risk pregnancies, respectively).

METHODS

This was a prospective, cross-sectional, questionnaire-based study. The sample consisted of postpartum women recruited from 2013 to 2015 at public maternity hospitals in the city of Niterói, Brazil. Participants were divided into two groups and completed a questionnaire consisting of Likert-scored items. Continuous variables were analyzed with the Mann-Whitney test, and categorical variables, with Fisher's test. A confirmatory factor analysis of participants' answers was performed.

RESULTS

Of 188 women enrolled, 54 (28.7%) had incomplete elementary education; 119 (62.2%) had attended more than six antenatal care visits. The mean age was 25.57 years. Nearly all women (n = 179, 95.2%) were roomed-in with their infants. Knowledge of neonatal screening was very similar in the high-complexity and low-complexity groups. Divergences were limited to items regarding the risks of neonatal screening.

CONCLUSIONS

The degree of knowledge among postpartum women was similar among high- and low-complexity facilities. Those who attended high-complexity facilities had longer hospital stays and greater adherence to ethical issues regarding neonatal screening.

[France and Great-Britain at the age of genomic medicine: new ethical challenges in reproductive medicine]

The announcement of the French Plan 'France Médecine Génomique 2015' demonstrates the will of the public authorities to make genomic medicine one of the flagships of public health and scientific research. It is against this backdrop that France announced its cooperation with Great Britain, one of the global leaders in genomics. The cooperation at an international level requires a common normative framework that addresses the new ethical challenges presented by genomic medicine. In order for such a framework to be adapted to different national contexts, it is important to identify and analyse the emerging ethical questions in general as well as within their specific national contexts. This article discusses the international implications of genomic medicine, and more precisely, the rise of international competitiveness in France. In a next step, the article explores the ethical implications of genomic medicine by taking the prenatal context as a case study. Finally, the article reflects on the way national contexts impact on the emerging ethical questions in France, as compared to Great Britain.

Neonatologists' Attitudes About Diagnostic Whole-Genome Sequencing in the NICU

Using focus group methodology, we studied the attitudes of neonatologists regarding diagnostic rapid genome sequencing for newborns who were critically ill in a NICU. One focus group took place within the first year after whole-genome sequencing testing became available, and another focus group took place 3 years later. Focus groups were audiotaped, transcribed, and analyzed by using standard techniques of grounded theory. Different analysts coded them for themes. The analysts then discussed differences and agreed on major themes. Twelve doctors participated in the first focus group, and 9 doctors participated in the second; 62% were attending physicians, and the rest were fellows. There were 14 women and 7 men. We did not collect any other demographic information on participants. Surprisingly, we found few differences between the earlier focus group and the later one. Comments were categorized as falling into 4 domains: (1) uncertainty about the interpretation of results, (2) issues about parental consent and limits on their right to know genomic information, (3) different opinions about whether and how genomic results could be clinically useful, and (4) potential harms of genomic testing.
