Abstract
Tumors constantly shed cancer cells that are considered the mediators of metastasis via the blood stream. Analysis of circulating cells and circulating cell-free DNA (cfDNA) in liquid biopsies, mostly taken from peripheral blood, have emerged as powerful biomarkers in oncology, as they enable the detection of genomic aberrations. Similarly, liquid biopsies taken from pregnant women serve as prenatal screening test for an abnormal number of chromosomes in the fetus, e.g., via the analysis of microchimeric fetal cells and cfDNA circulating in maternal blood. Liquid biopsies are minimally invasive and, consequently, associated with reduced risks for the patients. However, different challenges arise in oncology and pregnancy-acquired liquid biopsies with regard to the analyte concentration and biological (background) noise among other factors. In this review, we highlight the unique biological properties of circulating tumor cells (CTC), summarize the various techniques that have been developed for the enrichment, detection and analysis of CTCs as well as for analysis of genetic and epigenetic aberrations in cfDNA and highlight the range of possible clinical applications. Lastly, the potential, but also the challenges of liquid biopsies in oncology as well as their translational value for the analysis of pregnancy-acquired microchimerism are discussed.

Abstract
The objective of this study was to conduct qualitative research by clarifying the thoughts of pregnant women undergoing non-invasive prenatal testing (NIPT) in Japan, to collect evidence to provide information and psychosocial support in genetic counseling (GC). We attempted to conduct qualitative research to provide support for GC and the society in relation to children with special needs, by clarifying the thoughts of pregnant women undergoing NIPT. Between January 2016 and December 2017, we administered an open-ended questionnaire to pregnant Japanese women undergoing NIPT to clarify their ethical views in relation to children with special needs. The target population included 754 pregnant women who described their feelings and thoughts about undergoing NIPT and about children with special needs. Pregnant women undergoing NIPT have a variety of various mixed feelings and concerns. We classified the feelings and thoughts of pregnant women who underwent NIPT into the following four primary categories (multiple classifications): (1) perception about people with special needs (18.0%); (2) relation between NIPT and life selection (22.3%); (3) attitudes towards undergoing NIPT (47.5%); and (4) negative feelings and thoughts about raising children with special needs (48.1%). Most pregnant women undergoing NIPT expressed negative feelings and raising children with special needs. These feelings and thoughts may be one of the reasons why pregnant women undergo NIPT. In GC, it is important to also provide wide information on the social support and the current situation in the actual life of children with special needs.

Mainstreaming genetics into Italian prenatal care: exploring the future implementation of non-invasive prenatal testing (NIPT) in the Italian National Healthcare System using stakeholder interviews. BMJ PUBLIC HEALTH 2024; 2:e001074. [PMID: 40018638 PMCID: PMC11816205 DOI: 10.1136/bmjph-2024-001074] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 07/24/2024] [Indexed: 03/01/2025]
Abstract
Introduction Non-invasive prenatal testing (NIPT) has revolutionised the way prenatal testing is performed globally. Italy is one of the European countries considering incorporating NIPT nationwide into the publicly funded healthcare system. Given the extensive autonomy granted to the private sector, that not all technological applications result in equal benefits, and that only a few Italian regions currently offer NIPT through the public healthcare system free of charge, it is crucial to consider how to implement such a technology in the Italian public healthcare sector. Methods A qualitative study consisting of 12 semistructured interviews was performed. The study population included gynaecologists, geneticists, bioethicists, health economists and public health professionals. Non-probability sampling techniques were used to recruit the study's participants. Content analysis was employed to analyse the data. Results From the interviews, it emerged that a contingent implementation of NIPT for major chromosomal aneuploidies screening seems the most cost-effective and logical in the Italian context. No consensus was reached on fetal sex and sex chromosome aneuploidies screening. Most interviewees disagreed with making whole-genome/whole-exome sequencing available through the public sector. The high appreciation of NIPT, its potential to advance fundamental objectives of healthcare systems and its compatibility with the Italian prenatal testing culture are among the factors that may facilitate the transition of NIPT from the private to the public sector. Mainstreaming NIPT in the public healthcare system is challenged by its high costs, current offer, lack of prioritisation and regional differences. Conclusions While transitions take time and are challenging to achieve, this study shows that the current prenatal testing structure and practice would only need modest adjustments to accommodate NIPT, offering hope for the future. Future studies could expand this research by involving a broad range of stakeholders and investigating the effects of various NIPT implementation strategies presently employed across Italian regions.

Abstract
Egg freezing can allow women to preserve their eggs to avoid age-related infertility. The UK's recent extension of elective egg freezing storage has been welcomed as a way of enhancing the reproductive choices of young women who wish to delay having children. In this paper, I explore the issue of enhancing women's reproductive choices, questioning whether there is a more significant aspect overlooked in egg freezing. While increasing storage limits expands reproductive choices for some women, focus on this extension alone, I argue, misses a fundamental issue with egg preservation that often remains ignored; the importance of effective information on egg freezing and the effect this has on women's reproductive choices. Ultimately, I highlight the crucial role of balanced information in enhancing women's choices regarding egg freezing and argue that focusing on extending and increasing provision may obscure this real opportunity to empower women and their authentic reproductive choices.

Abstract
Hereditary cancer syndromes (HCS) predispose individuals to a higher risk of developing multiple cancers. However, current screening strategies have limited ability to screen for all cancer risks. Circulating tumour DNA (ctDNA) detects DNA fragments shed by tumour cells in the bloodstream and can potentially detect cancers early. This study aimed to explore patients' perspectives on ctDNA's utility to help inform its clinical adoption and implementation. We conducted a qualitative interpretive description study using semi-structured phone interviews. Participants were purposively sampled adult HCS patients recruited from a Canadian HCS research consortium. Thirty HCS patients were interviewed (n = 19 women, age range 20s-70s, n = 25 were white). Participants were highly concerned about developing cancers, particularly those without reliable screening options for early detection. They "just wanted more" than their current screening strategies. Participants were enthusiastic about ctDNA's potential to be comprehensive (detect multiple cancers), predictive (detect cancers early) and tailored (lead to personalized clinical management). Participants also acknowledged ctDNA's potential limitations, including false positives/negatives risks and experiencing additional anxiety. However, they saw ctDNA's potential benefits outweighing its limitations. In conclusion, participants' belief in ctDNA's potential to improve their care overshadowed its limitations, indicating patients' support for using ctDNA in HCS care.

Abstract
BACKGROUND Prenatal genetic testing, in particular non-invasive prenatal testing (NIPT), as well as screening for risks associated with pregnancy, and counseling, play pivotal roles in reproductive healthcare, offering valuable information about the health of the fetus to expectant parents. This study aims to delve into the perspectives and experiences of women considering genetic testing and screening during pregnancy, focusing on their decision-making processes and the implications for informed consent. METHODS A nationwide qualitative study was conducted in Switzerland, involving in-depth interviews with women who were 1 to 2 years post-partum, covered by basic compulsory Swiss insurance, including women with a migration background. Thematic analysis was employed to identify key themes and patterns in the data. RESULTS The findings underscore the significance of effective communication during prenatal counseling, suggesting that healthcare providers could not only convey technical information but also support women in their decision-making processes. Women need comprehensive information about genetic testing and its implications, as well as the reasons for screening during pregnancy, as there might be a need to bridge knowledge gaps and clarify misconceptions. Furthermore, the study highlights the multifaceted nature of decision-making, with women considering factors such as uncertainty, values, emotional responses, and societal support systems. The concept of acceptance emerged as a crucial theme, with some women expressing their readiness to love and accept their child, regardless of genetic anomalies or disabilities. CONCLUSION This study offers valuable insights into the perspectives and needs of women regarding prenatal genetic testing, screening, and counseling in Switzerland. It underscores the importance of enhancing the clinical interaction and informed consent process by providing comprehensive information, addressing misconceptions, and supporting women in decision-making about pregnancy management and the management of the child's health, following prenatal genetic testing, including NIPT. These findings can inform healthcare providers and policymakers in improving the quality of prenatal counseling, ensuring informed consent, and supporting women in making well-informed and meaningful decisions about genetic testing, and on the use of screening during pregnancy.

Abstract
BACKGROUND In X-linked hypohidrotic ectodermal dysplasia (XLHED), ectodysplasin A1 (EDA1) deficiency results in malformation of hair, teeth, and sweat glands. Lack of sweating which can cause life-threatening hyperthermia is amenable to intrauterine therapy with recombinant EDA1. OBJECTIVES This study aimed at evaluating reproductive decision-making by women with XLHED and at clarifying the potential impact of a prenatal treatment option. METHODS In a retrospective cross-sectional analysis, a 75-item questionnaire filled in by 50 women with XLHED (age 19-49 years) was assessed. RESULTS 16 women (32%) prevented pregnancies because of the risk to pass on XLHED, 15 considered assisted reproduction for the same reason. Twelve women had a history of miscarriage, stillbirth or abortion, three women reported on previous abortion of affected fetuses. When imagining to be pregnant, all except one showed interest in prenatal diagnosis of XLHED and in the possibility of treatment before birth. In 13 out of 50 women (26%), XLHED if detected prenatally would have impact on the continuation of pregnancy. Among 35 mothers of at least one affected child, XLHED had rarely been diagnosed during the first pregnancy (17%) but regularly during subsequent pregnancies (77%). Becoming aware of the condition before birth had caused a moral conflict for 50% of these women. Subjects with an affected child less frequently considered assisted reproduction to prevent XLHED (p<0.05). In more than 66% of the women who reported an effect of XLHED on family planning, a prenatal treatment option for this disease would influence their decision-making. CONCLUSIONS Many pregnant XLHED carriers who seek prenatal diagnosis experience moral conflicts. A prenatal treatment option would have strong impact on reproductive decisions, underlining the importance of adequate professional counselling.

Abstract
Direct-to-consumer (DTC) genetic testing exists largely outside of any regulatory schemes, and studies providing a comprehensive overview of the ethical, social, legal, and technological considerations for regulating these types of technologies are lacking. This paper uses the 3-I framework for policy analysis to analyze the ideas, interests, and institutions relevant to policy development for DTC genetic testing in North America and internationally. A scoping review was conducted. Citation databases were searched for papers addressing the ethical, social, legal, and technological implications of DTC genetic testing; stakeholder perspectives on and experiences with DTC genetic testing; or the effect of such testing on the healthcare system. Ninety-nine publications, organizational reports, governmental documents, or pieces of legislation were included. The ideas included are autonomy, informed decision making, privacy, and clinical validity and utility. The interests discussed are those of the public and healthcare providers. The institutions included are regulatory organizations such as the Food and Drug Administration in the United States, laws governing the implementation or delivery of genetic testing in general, and legislation created to protect against genetic discrimination. This analysis clarifies the ethical, social, legal, and technological issues of DTC genetic testing regulation. This information can be used by policy makers to develop or strengthen regulations for DTC genetic testing such as requiring an assessment of the clinical validity of tests before they become publicly available, controlling how tests are marketed, and stipulating requirements for healthcare provider involvement and informed consent.

Abstract
Prenatal genetic testing is becoming available for an increasingly broad set of diseases, and it is only a matter of time before parents can choose to test for hundreds, if not thousands, of genetic conditions in their fetuses. Should access to certain kinds of fetal genetic information be limited, and if so, on what basis? We evaluate a range of considerations including reproductive autonomy, parental rights, disability rights, and the rights and interests of the fetus as a potential future child. We conclude that parents should be able to access information that could be useful during pregnancy, but that testing for non-medical information should be limited. Next, we argue that the government lacks a compelling state interest in regulating prenatal genetic testing and propose that regulation should occur through medical professional organizations. Finally, we present a framework for determining what testing physicians should recommend, offer neutrally, or not offer at all.

Abstract
Women's views on responsible motherhood influence decision-making regarding participation in prenatal screening. Previous studies showed that the probabilistic nature of the first-trimester combined test and the potential requirement for subsequent invasive diagnostics serve as legitimate reasons for women to exclude prenatal screening from their moral responsibilities. These moral barriers might now be less relevant with the introduction of the non-invasive prenatal test (NIPT) resulting in women feeling a moral duty to use NIPT screening as part of responsible motherhood. This qualitative study explores the impact of NIPT on women's moral beliefs about the meaning of prenatal screening in relation to responsible motherhood. We performed semi-structured interviews with 29 pregnant women who were offered NIPT as a first-tier screening test within a Dutch nationwide study (TRIDENT-2). Results show that the inherent uncertainty about the fetus's health despite improved accuracy and the lack of treatment for a detected disorder, combined with the possibility to obtain information about actionable anomalies through the fetal anomaly scan, support women's perspectives that NIPT is not an obligation of responsible motherhood. Acceptance of NIPT is considered to be a free decision related to the information each woman needs to be a good mother for her child and her family. Women's views may change when NIPT has expanded to include treatable or preventable conditions.

Abstract
BACKGROUND With the help of ART, an advanced parental age is not considered to be a serious obstacle for reproduction anymore. However, significant health risks for future offspring hide behind the success of reproductive medicine for the treatment of reduced fertility associated with late parenthood. Although an advanced maternal age is a well-known risk factor for poor reproductive outcomes, understanding the impact of an advanced paternal age on offspring is yet to be elucidated. De novo monogenic disorders (MDs) are highly associated with late fatherhood. MDs are one of the major sources of paediatric morbidity and mortality, causing significant socioeconomic and psychological burdens to society. Although individually rare, the combined prevalence of these disorders is as high as that of chromosomal aneuploidies, indicating the increasing need for prenatal screening. With the help of advanced reproductive technologies, families with late paternity have the option of non-invasive prenatal testing (NIPT) for multiple MDs (MD-NIPT), which has a sensitivity and specificity of almost 100%. OBJECTIVE AND RATIONALE The main aims of the current review were to examine the effect of late paternity on the origin and nature of MDs, to highlight the role of NIPT for the detection of a variety of paternal age-associated MDs, to describe clinical experiences and to reflect on the ethical concerns surrounding the topic of late paternity and MD-NIPT. SEARCH METHODS An extensive search of peer-reviewed publications (1980-2021) in English from the PubMed and Google Scholar databases was based on key words in different combinations: late paternity, paternal age, spermatogenesis, selfish spermatogonial selection, paternal age effect, de novo mutations (DNMs), MDs, NIPT, ethics of late fatherhood, prenatal testing and paternal rights. OUTCOMES An advanced paternal age provokes the accumulation of DNMs, which arise in continuously dividing germline cells. A subset of DNMs, owing to their effect on the rat sarcoma virus protein-mitogen-activated protein kinase signalling pathway, becomes beneficial for spermatogonia, causing selfish spermatogonial selection and outgrowth, and in some rare cases may lead to spermatocytic seminoma later in life. In the offspring, these selfish DNMs cause paternal age effect (PAE) disorders with a severe and even life-threatening phenotype. The increasing tendency for late paternity and the subsequent high risk of PAE disorders indicate an increased need for a safe and reliable detection procedure, such as MD-NIPT. The MD-NIPT approach has the capacity to provide safe screening for pregnancies at risk of PAE disorders and MDs, which constitute up to 20% of all pregnancies. The primary risks include pregnancies with a paternal age over 40 years, a previous history of an affected pregnancy/child, and/or congenital anomalies detected by routine ultrasonography. The implementation of NIPT-based screening would support the early diagnosis and management needed in cases of affected pregnancy. However, the benefits of MD-NIPT need to be balanced with the ethical challenges associated with the introduction of such an approach into routine clinical practice, namely concerns regarding reproductive autonomy, informed consent, potential disability discrimination, paternal rights and PAE-associated issues, equity and justice in accessing services, and counselling. WIDER IMPLICATIONS Considering the increasing parental age and risks of MDs, combined NIPT for chromosomal aneuploidies and microdeletion syndromes as well as tests for MDs might become a part of routine pregnancy management in the near future. Moreover, the ethical challenges associated with the introduction of MD-NIPT into routine clinical practice need to be carefully evaluated. Furthermore, more focus and attention should be directed towards the ethics of late paternity, paternal rights and paternal genetic guilt associated with pregnancies affected with PAE MDs.

Abstract
Since its introduction in 2011, noninvasive prenatal testing (NIPT) has spread rapidly around the world. It carries numerous benefits but also raises challenges, often related to sociocultural, legal, and economic contexts. This article describes the implementation of NIPT in nine countries, each with its own unique characteristics: Australia, Canada, China and Hong Kong, India, Israel, Lebanon, the Netherlands, the United Kingdom, and the United States. Themes covered for each country include the structure of the healthcare system, how NIPT is offered, counseling needs and resources, and cultural and legal context regarding disability and pregnancytermination. Some common issues emerge, including cost as a barrier to equitable access, the complexity of decision-making about public funding, and a shortage of appropriate resources that promote informed choice. Conversely, sociocultural values that underlie the use of NIPT vary greatly among countries. The issues described will become even more challenging as NIPT evolves from a second-tier to a first-tier screening test with expanded use.

Abstract
An enduring ethical dispute accompanies prenatal screening and testing (PST) technologies. This ethical debate focuses on notions of reproductive choice. On one side of the dispute are those who have supported PST as a way to empower women's reproductive choice, while on the other side are those who argue that PST, particularly when made a routine part of prenatal care, limits deliberate choice. Empirical research does not resolve this ethical debate with evidence both of women for whom PST enhances their choices but also persistent evidence of recurrent problems between PST and women's autonomous decision-making. While there have been attempts to remove challenges to reproductive choice, it has been argued that these challenges cannot be removed entirely. In this paper I provide a historical review of PST technologies' development and in doing so provide a detailed insight into the root causes of this tension between the opposing sides of this debate. This historical account provides evidence that those who championed the early use of these technologies did so in order to achieve a number of wholly different goals other than women's choice and empowerment. These different aims focus on scientific discovery and eugenic goals and, I argue, are irreconcilable with women's choice and empowerment. It thus may not be surprising that the resulting practice of PST continues to resist compatibility with women's choice and empowerment. Ultimately, by understanding the historical foundations of PST we can more effectively assess how to reconcile women's reproductive autonomy with routine prenatal screening.

Abstract
Non-invasive prenatal testing (NIPT) is a genomic technology used to predict the chance of a foetus having a genetic condition. Despite the immediacy of this technology’s integration into clinical practice, there is a dearth of evidence outlining how both patients and professionals experience NIPT on the ground. In this article, we draw upon our collective empirical research—specifically on earlier screening technologies (BKR), Down syndrome screening (GT), genetic screening/testing (JL) and NIPT (HS)—to outline the most pressing and often controversial issues which, we argue, remain unresolved and vital to consider regarding NIPT. We begin with a brief introduction to NIPT as a prenatal technology and the bodies of literature which unpack its ‘social life’. In what follows, BKR discusses NIPT within the context of her research on ‘the tentative pregnancy’ and diagnostic testing in the USA. In the following sections, GT, HS and JL identify different, but related, concerns with respect to NIPT, particularly around routinisation, commercialisation, choice, abortion, and configurations of disability and ‘normalcy’.

Abstract
This review examines the factors that affect the decision-making process of parental couples evaluating prenatal screening and diagnostic tests. A systematic search was performed using PubMed and PsycInfo databases. The 46 included studies had to: investigate the decision-making process about prenatal testing; focus on tests detecting trisomy 21, 18, 13, and abnormalities of sex chromosomes; be published in English peer-reviewed journals. The decision-making process seems composed of different levels: an individual level with demographic, clinical, and psychological aspects; a contextual level related to the technical features of the test and the information received; a relational level involving family and society.

Abstract
Background Egg freezing has emerged as a technology of assisted reproductive medicine that allows women to plan for the anticipated loss of fertility and hence to preserve the option to conceive with their own eggs. The technology is surrounded by value-conflicts and is subject to ongoing discussions. This study aims at contributing to the empirical-ethical debate by exploring women’s viewpoints on egg freezing in Austria,
where egg freezing for social reasons is currently not allowed. Methods Q-methodology was used to identify prevailing viewpoints on egg freezing. 46 female participants ranked a set of 40 statements onto a 9-column forced choice ranking grid according to the level of agreement. Participants were asked to explain their ranking in a follow-up survey. By-person factor analysis was used to identify distinct viewpoints which were interpreted using both the quantitative and the qualitative data. Results Three distinct viewpoints were identified: (1) “women should decide for themselves”, (2) “we should accept nature but change policy”, and (3) “we need an informed societal debate”. These viewpoints provide insights into how biomedical innovations such as egg freezing are perceived by women in Austria and illustrate the normative tensions regarding such innovations. Conclusions Acknowledging the different prioritizations of values regarding assisted reproductive technologies is important to better understand the underlying normative tensions in a country where egg freezing for social reasons is currently not allowed. The study adds new empirical insights to the ongoing debate by outlining and discussing viewpoints of those directly affected: women. Following up on the lay persons perspective is particularly important in the context of future biomedical innovations that may challenge established norms and create new tensions. It therefore also adds to the societal debate and supports evidence-informed policy making in that regard.

Abstract
Non-invasive prenatal testing (NIPT) using cell-free DNA (cfDNA) offers numerous benefits to pregnant women and their families. It also raises ethical, legal and social concerns regarding, for instance, the possible effects of a routinization of prenatal genetic testing on free and informed decision-making by prospective parents, and the role of the state in governing its use. Technological advances are allowing cfDNA analyses to detect an increasing number of genetic risks and conditions in the fetus, potentially further exacerbating such concerns. From May 2015 to December 2016, we conducted a three-round Policy Delphi study (NR1 = 61, NR2 = 58, NR3 = 47; overall retention rate = 77.0%) to explore the social acceptability (SA) of current and potential future uses of NIPT in Canada according to participants with relevant professional, research or advocacy expertise. Participants came from four groups: healthcare professionals (NR3 = 14), social sciences and humanities researchers (NR3 = 13), patients/disability rights advocates (NR3 = 14), and cultural/religious communities advocates (NR3 = 6). This paper presents SA criteria and contextual contingencies relevant to the assessment of NIPT's SA according to the group. It also reports what uses (conditions or motives) participants thought should be banned, permitted, publicly funded, or promoted as a public health strategy. According to them, conditions resulting in severe pain or early death, as well as trisomies (13, 18, 21) and sex chromosome abnormalities, should be covered by Canadian public health insurance. However, there was wide agreement that direct-to-consumer NIPT should be legally banned, and that testing for fetal sex for non-medical reasons using NIPT should be either proscribed or discouraged. In addition to identifying areas of consensus, our results point to disagreement regarding, for instance, the required level of governance of whole-genome sequencing and testing for late onset conditions with low penetrance. This study also provides a model for exploring the SA of emerging technologies using the Policy Delphi method.

Abstract
Background The clinical introduction of non-invasive prenatal testing for fetal aneuploidies is currently transforming the landscape of prenatal screening in many countries. Since it is noninvasive, safe and allows the early detection of abnormalities, NIPT expanded rapidly and the test is currently commercially available in most of the world. As NIPT is being introduced globally, its clinical implementation should consider various challenges, including the role of the surrounding social and cultural contexts. We conducted a qualitative study with healthcare professionals in Lebanon and Quebec as case studies, to highlight the relevance of cultural contexts and to explore the concerns that should be taken into account for an ethical implementation of NIPT. Methods We conducted semi-structured interviews with 20 healthcare professionals (HCPs), 10 from each country, practicing in the field of prenatal screening and follow up diagnostic testing, including obstetricians and gynecologists, nurses, medical geneticists and, genetic counselors. We aimed to 1) explore HCPs’ perceptions and views regarding issues raised by NIPT and 2) to shed light on ways in which the introduction of the same technology (NIPT) in two different contexts (Lebanon and Quebec) raises common and different challenges that are influenced by the cultural norms and legal policies in place. Results We identified challenges to the ethical implementation of NIPT. Some are common to both contexts, including financial/economic, social, and organizational/ educational challenges. Others are specific to each context. For example, challenges for Lebanon include abortion policy and financial profit, and in Quebec challenges include lobbying by Disability rights associations and geographical access to NIPT. Conclusions Our findings highlight the need to consider specific issues related to various cultural contexts when developing frameworks that can guide an ethically sound implementation of NIPT. Further, they show that healthcare professional education and training remain paramount in order to provide NIPT counseling in a way that supports pregnant women and couples’ choice.

Abstract
OBJECTIVE To explore informed decision making for prenatal aneuploidy screening (PAS) by investigating the relationships among women's understanding of PAS, their health literacy, and their satisfaction with their decisions regarding PAS. DESIGN A descriptive, cross-sectional, correlational study. SETTING Southeastern United States. PARTICIPANTS Ninety-five adult women who were at least 18 weeks pregnant; most were White non-Hispanic (n = 75, 78.9%) and college educated (n = 56, 59.0%). METHODS Potential participants were invited to complete an online survey that was distributed via e-mail to recipients of an electronic pregnancy and parenting newsletter. The survey included questions about women's understanding of PAS, their health literacy, and their satisfaction with their decisions regarding PAS based on three validated instruments. I used descriptive statistics, bivariate correlational analysis, and multiple linear regression to analyze the data. RESULTS Higher level of education (β =.225, p = .038) and higher scores from the Health Literacy Questionnaire's scale Ability to Actively Engage With Health Care Providers (β =.317, p = .004) were significantly associated with increased understanding of PAS. Higher scores on two scales from the Health Literacy Questionnaire, Feeling Understood andSupportedby Health Care Providers (β =.329 , p = .004) and Ability to Find Good Health Information (β = .402, p = .013), were significantly associated with greater satisfaction with decisions regarding prenatal aneuploidy screening. Forty-two percent (n = 40) of participants did not report satisfaction with PAS. CONCLUSION A woman's health literacy and her ability to actively engage with health care providers are critical for informed decision making about PAS. Findings highlight the need for woman-centered strategies to promote open and intentional communication about PAS.

Abstract
The noninvasive prenatal test (NIPT) as the first trimester prenatal screening (FTS) for trisomies 21, 18, and 13 is offered to all pregnant women in the Netherlands. NIPT using genome sequencing allows for an expansion of the scope of FTS and the introduction of NIPT gives rise to ethical and societal concerns about deliberated decision‐making, pressure to engage in screening, and possible lack of equal access due to the financial contribution (€175) to NIPT. We explored the opinions and experiences of pregnant women, who were offered FTS, about these concerns, and the possibility of a broadened scope. Nineteen pregnant women representing a diversity of backgrounds were interviewed using a semi‐structured interview guide. Eight women did not opt for prenatal screening while 11 did (NIPT = 4, combined test = 7). Women experienced a free choice to accept or decline prenatal screening, despite sometimes receiving advice from others. Prior to pretest counseling, some women had already deliberated about what an abnormal test result would mean to them. Others accepted or declined FTS without deliberation. The current Dutch policy of requiring a co‐payment was acceptable to some, who believed that it functioned as a threshold to think carefully about FTS. Others were concerned that a financial threshold would lead to unequal access to screening. Finally, pregnant women found it difficult to formulate opinions on the scope of FTS, because of lack of knowledge. Life expectancy, severity, and treatability were considered important criteria for the inclusion of a condition in NIPT.

Abstract
Background Pregnant people have a risk of carrying a fetus affected by a chromosomal anomaly. Prenatal screening is offered to pregnant people to assess their risk. In recent years, noninvasive prenatal testing (NIPT) has been introduced clinically, which uses the presence of circulating cell-free fetal DNA in the maternal blood to quantify the risk of a chromosomal anomaly. At present, NIPT is publicly funded for pregnancies at high risk of a chromosomal anomaly, and available to pregnant people at average risk if they choose to pay out of pocket. Methods We performed a systematic review of primary, empirical qualitative research that describes the experiences and perspectives of pregnant people, their families, clinicians, and others with lived experience relevant to NIPT. We were interested in the beliefs, experiences, preferences, and perspectives of these groups. We analyzed the evidence available in 36 qualitative and mixed-methods studies using the integrative technique of qualitative meta-synthesis. Results Most people (pregnant people, clinicians, and others with relevant lived experience) said that NIPT offered important information to pregnant people and their partners. Most people were very enthusiastic about widening access to NIPT because it can provide information about chromosomal anomalies quite early in pregnancy, with relatively high accuracy, and without risk of procedure-related pregnancy loss. However, many groups cautioned that widening access to NIPT may result in routinization of this test, causing potential harm to pregnant people, their families, the health care system, people living with disabilities, and society as a whole. Widened logistical, financial, emotional, and informational access may be perceived as a benefit, but it can also confer harm on various groups. Many of these challenges echo historical critiques of other forms of prenatal testing, with some issues mitigated or exacerbated by the particular features of NIPT. Conclusions Noninvasive prenatal testing offers significant benefit for pregnant people but may also be associated with potential harms related to informed decision-making, inequitable use, social pressure to test, and reduced support for people with disabilities.

Facilitating informed choice about non-invasive prenatal testing (NIPT): a systematic review and qualitative meta-synthesis of women's experiences. BMC Pregnancy Childbirth 2019; 19:27.

Abstract
BACKGROUND Non-invasive prenatal testing (NIPT) can be used to accurately detect fetal chromosomal anomalies early in pregnancy by assessing cell-free fetal DNA present in maternal blood. The rapid diffusion of NIPT, as well as the ease and simplicity of the test raises concerns around informed decision-making and the potential for routinization. Introducing NIPT in a way that facilitates informed and autonomous decisions is imperative to the ethical application of this technology. We approach this imperative by systematically reviewing and synthesizing primary qualitative research on women's experiences with and preferences for informed decision-making around NIPT. METHODS We searched multiple bibliographic databases including Ovid MEDLINE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), and ISI Web of Science Social Sciences Citation Index (SSCI). Our review was guided by integrative qualitative meta-synthesis, and we used a staged coding process similar to that of grounded theory to conduct our analysis. RESULTS Thirty empirical primary qualitative research studies were eligible for inclusion. Women preferred to learn about NIPT from their clinicians, but they expressed dissatisfaction with the quality and quantity of information provided during counselling and often sought information from a variety of other sources. Women generally had a good understanding of test characteristics, and the factors of accuracy, physical risk, and test timing were the critical information elements that they used to make informed decisions around NIPT. Women often described NIPT as easy or just another blood test, highlighting threats to informed decision-making such as routinization or a pressure to test. CONCLUSIONS Women's unique circumstances modulate the information that they value and require most in the context of making an informed decision. Widened availability of trustworthy information about NIPT as well as careful attention to the facilitation of counselling may help facilitate informed decision-making.

Abstract
BACKGROUND Noninvasive prenatal testing is a recent technology that provides some genetic information about the fetus through the analysis of cell-free fetal DNA circulating in maternal blood. We aimed to identify the benefits, challenges and guiding ethical principles most relevant to the clinical integration of noninvasive prenatal testing in Canada, according to experts throughout the country. METHODS We conducted a 3-round Delphi study involving Canadian experts of contemporary discussions about the ethical and societal implications of prenatal testing and genomic technologies. In round 1, we asked participants to identify clinical benefits and challenges related to the implementation of noninvasive prenatal testing in Canada, and the ethical principles they think should guide it. In round 2, we asked participants to select the most important elements stated by their peers. In round 3, participants were informed of the aggregated results from round 2, and invited to revise or confirm their selection. RESULTS Round 1 had a participation rate of 20.2%, and involved 61 participants. Subsequent rounds 2 and 3 had retention rates of 95.1% (n = 58) and 84.5% (n = 49), respectively. Through these discussions, we identified 3 lists of benefits (n = 10), challenges (n = 27), and ethical principles (n = 16) prioritized by Canadian experts as being most relevant to the implementation of noninvasive prenatal testing in Canada. INTERPRETATION Although multiple and diverse potential issues were identified, Canadian experts agreed on 2 sets of requirements for the responsible implementation of noninvasive prenatal testing in Canada. Interdisciplinary appraisals may be instrumental to responsible policy-making related to the implementation of noninvasive prenatal testing in Canada.

Ngan OMY, Yi H, Ahmed S. Service provision of non-invasive prenatal testing for Down syndrome in public and private healthcare sectors: a qualitative study with obstetric providers. BMC Health Serv Res 2018; 18:731. [PMID: 30241520 PMCID: PMC6150999 DOI: 10.1186/s12913-018-3540-9] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2017] [Accepted: 09/14/2018] [Indexed: 01/09/2023] Open
Abstract
Background Cell-free fetal DNA sequencing based non-invasive prenatal testing (NIPT) for Down syndrome (DS) has become widely available. In Hong Kong, obstetric providers in the public sector refer women identified at high risk of having a child with Down syndrome to obstetric providers in the private sector for NIPT. Little is known about how the NIPT has been adopted in the public sector where DS screening is provided for free of charge. The study aimed to identify the factors influencing providers’ role enactment, such as consultation and referral, in the service provision of NIPT for DS in public and private healthcare sectors. Methods In-depth interviews were conducted with 20 obstetric providers offering NIPT in Hong Kong. Thematic narrative analysis was used to identify (i) the factors considered by participants when referring women for NIPT for Down syndrome in public and private healthcare sectors and (ii) their perceptions of the need to integrate NIPT into the current public antenatal service. Results Participants raised concerns about the lack of transparent referral guideline between public and private sectors for NIPT. Public obstetric providers reported little obligation to provide women with much information about risks and benefits of NIPT as it was not provided by public sectors. Some private providers assumed that women referred from the public sector had already received sufficient information about NIPT. The providers were also concerned about potential application of NIPT for further detection without regulation. Conclusions Although the providers had good knowledge of clinical advantages of NIPT over conventional screening, they were uncertain about how to introduce NIPT to women. Guidelines are necessary to enable better coordination of public and private sectors services to enable women to make informed choices about the uptake of NIPT.
