Potentiality switches and epistemic uncertainty: the Argument from Potential in times of human embryo-like structures.

Recent advancements in developmental biology enable the creation of embryo-like structures from human stem cells, which we refer to as human embryo-like structures (hELS). These structures provide promising tools to complement-and perhaps ultimately replace-the use of human embryos in clinical and fundamental research. But what if these hELS-when further improved-also have a claim to moral status? What would that imply for their research use? In this paper, we explore these questions in relation to the traditional answer as to why human embryos should be given greater protection than other (non-)human cells: the so-called Argument from Potential (AfP). According to the AfP, human embryos deserve special moral status because they have the unique potential to develop into persons. While some take the development of hELS to challenge the very foundations of the AfP, the ongoing debate suggests that its dismissal would be premature. Since the AfP is a spectrum of views with different moral implications, it does not need to imply that research with human embryos or hELS that (may) have 'active' potential should be completely off-limits. However, the problem with determining active potential in hELS is that this depends on development passing through 'potentiality switches' about the precise coordinates of which we are still in the dark. As long as this epistemic uncertainty persists, extending embryo research regulations to research with specific types of hELS would amount to a form of regulative precaution that as such would require further justification.

Uncertain futures and unsolicited findings in pediatric genomic sequencing: guidelines for return of results in cases of developmental delay.

BACKGROUND: Massively parallel sequencing techniques, such as whole exome sequencing (WES) and whole genome sequencing (WGS), may reveal unsolicited findings (UFs) unrelated to the diagnostic aim. Such techniques are frequently used for diagnostic purposes in pediatric cases of developmental delay (DD). Yet policy guidelines for informed consent and return of UFs are not well equipped to address specific moral challenges that may arise in these children's situations. DISCUSSION: In previous empirical studies conducted by our research group, we found that it is sometimes uncertain how children with a DD will develop and whether they could come to possess capacities for autonomous decision-making in the future. Parents sometimes felt this brought them into a Catch-22 like situation when confronted with choices about UFs before undergoing WES in trio-analysis (both the parents' and child's DNA are sequenced). An important reason for choosing to consent to WES was to gain more insight into how their child might develop. However, to make responsible choices about receiving or declining knowledge of UFs, some idea of their child's future development of autonomous capacities is needed. This undesirable Catch-22 situation was created by the specific policy configuration in which parents were required to make choices about UFs before being sequencing (trio-analysis). We argue that this finding is relevant for reconfiguring current policies for return of UFs for WES/WGS and propose guidelines that encompass two features. First, the informed consent process ought to be staged. Second, differing guidelines are required for withholding/disclosing a UF in cases of DD appropriate to the level of confidence there is about the child's future developmental of autonomous capacities. CONCLUSION: When combined with a dynamic consent procedure, these two features of our guidelines could help overcome significant moral challenges that present themselves in the situations of children undergoing genomic sequencing for clarifying a DD.

Consanguineous couples' experiences and views regarding expanded carrier screening: Barriers and facilitators in the decision-making process.

Expanded carrier screening (ECS) entails a screening offer for multiple recessive disorders at the same time, and allows testing of individuals or couples regardless of ancestry or geographic origin. Children of consanguineous couples have a higher-than-average risk of manifesting autosomal recessive disorders. This study aims to contribute to the responsible implementation of ECS for consanguineous couples. Seven semi-structured interviews were conducted with consanguineous couples who had recently participated in Whole Exome Sequencing (WES)-based ECS at Maastricht University Medical Center (MUMC+), the Netherlands. The test offered at MUMC+ covers a large number of disease-related genes (~2000), including severe, relatively mild, early- and late-onset disorders. Respondents were interviewed about their views on, and experiences with participation in WES-based ECS. Overall, participation was experienced as worthwhile: it enabled respondents to make informed choices with regard to family planning as well as to take on the presumed parental responsibility to deliver their children as healthy as possible. Furthermore, our findings suggest that (1) true consent for having this test requires timely information about the possible implications of a positive test result for specific categories of findings, as well as about the success rates of the available reproductive options; (2) the clinical geneticist can play a pivotal part in informing participants as well as providing clear information about autosomal recessive inheritance; (3) more research is needed to explore what type of genetic risk information is considered 'meaningful' by participants and actually contributes to reproductive decision-making.

Towards understanding accountability for physicians practice in India.

The lack of accountability is considered to be a major cause of the crisis in health care in India. Physicians as key stakeholders in the health care delivery system have traditionally been accountable for health concerns at the doctor-patient interface. Following social and organizational dynamics, the interpretations of accountability have broadened and shifted in the recent literature, expanding accountability to the community, national and global levels and to social domains. The objective of this study is to provide a comprehensive framework of accountability in medical practice that can be used as a vehicle for further contextualized research and policy input. Through literature review, this paper is presented in two parts. First, a description of accountability of a physician inclusive of the social domains is extracted by posing three pertinent questions: who is accountable? accountability to whom? and accountability for what? which addresses the roles, relationships with other stakeholders and domains of accountability. Second, a framework of accountability of a physician is designed and presented to illustrate the professional and social domains. This study revealed a shift from individual physician's accountability to collective accountability involving multiple stakeholders through complex reciprocal and multi-layered mechanisms inclusive of the social dimensions. We propose a comprehensive framework of accountability of the physician to include the social domains that its multidimensional and integrative of all stakeholders. Furthermore, we discuss the utility of the framework in the Indian health care system and how this can facilitate further research in understanding the social dimensions of all stakeholders.

[Broadening NIPT needs more care]. / Zoeken naar 'nevenbevindingen'?

In a research setting (TRIDENT-2), Dutch pregnant women undergoing prenatal screening for trisomies 21, 18 and 13 with the Non-Invasive Prenatal Test (NIPT), are offered the choice to also receive information about incidental findings. In a recent report, the Health Council of the Netherlands has recommended to retain this option, but to only report those incidental findings that very probably will lead to serious health outcomes for the child. A working group has been appointed to draw up a guideline for this. In this article we argue that actively searching for desired 'incidental findings' in fact amounts to broadening the scope of the screening and that a justification of this choice is still lacking. A core issue is whether the benefits of such broader screening outweigh the drawback of inevitably also generating findings that do not fit in with the aim of the screening: providing meaningful reproductive choices.

Exome/Genome-Wide Testing in Newborn Screening: A Proportionate Path Forward.

Population-based newborn screening (NBS) is among the most effective public health programs ever launched, improving health outcomes for newborns who screen positive worldwide through early detection and clinical intervention for genetic disorders discovered in the earliest hours of life. Key to the success of newborn screening programs has been near universal accessibility and participation. Interest has been building to expand newborn screening programs to also include many rare genetic diseases that can now be identified by exome or genome sequencing (ES/GS). Significant declines in sequencing costs as well as improvements to sequencing technologies have enabled researchers to elucidate novel gene-disease associations that motivate possible expansion of newborn screening programs. In this paper we consider recommendations from professional genetic societies in Europe and North America in light of scientific advances in ES/GS and our current understanding of the limitations of ES/GS approaches in the NBS context. We invoke the principle of proportionality-that benefits clearly outweigh associated risks-and the human right to benefit from science to argue that rigorous evidence is still needed for ES/GS that demonstrates clinical utility, accurate genomic variant interpretation, cost effectiveness and universal accessibility of testing and necessary follow-up care and treatment. Confirmatory or second-tier testing using ES/GS may be appropriate as an adjunct to conventional newborn screening in some circumstances. Such cases could serve as important testbeds from which to gather data on relevant programmatic barriers and facilitators to wider ES/GS implementation.

[Is germ-line genome modification ethically justified?] / Is kiembaanmodificatie ethisch verantwoord?

As the normative objections to (human) germline genome editing cannot convincingly justify a categorical prohibition of such editing, its present prohibition should be replaced by a strict regulation, i.e. a conditional allowance. If safe and effective, germline genome editing may become a useful reproductive option.

Liquid biopsy: state of reproductive medicine and beyond.

Liquid biopsy is the process of sampling and analyzing body fluids, which enables non-invasive monitoring of complex biological systems in vivo. Liquid biopsy has myriad applications in health and disease as a wide variety of components, ranging from circulating cells to cell-free nucleic acid molecules, can be analyzed. Here, we review different components of liquid biopsy, survey state-of-the-art, non-invasive methods for detecting those components, demonstrate their clinical applications and discuss ethical considerations. Furthermore, we emphasize the importance of artificial intelligence in analyzing liquid biopsy data with the aim of developing ethically-responsible non-invasive technologies that can enhance individualized healthcare. While previous reviews have mainly focused on cancer, this review primarily highlights applications of liquid biopsy in reproductive medicine.

Towards a Responsible Transition to Learning Healthcare Systems in Precision Medicine: Ethical Points to Consider.

Learning healthcare systems have recently emerged as a strategy to continuously use experiences and outcomes of clinical care for research purposes in precision medicine. Although it is known that learning healthcare transitions in general raise important ethical challenges, the ethical ramifications of such transitions in the specific context of precision medicine have not extensively been discussed. Here, we describe three levers that institutions can pull to advance learning healthcare systems in precision medicine: (1) changing testing of individual variability (such as genes); (2) changing prescription of treatments on the basis of (genomic) test results; and/or (3) changing the handling of data that link variability and treatment to clinical outcomes. Subsequently, we evaluate how patients can be affected if one of these levers are pulled: (1) patients are tested for different or more factors than before the transformation, (2) patients receive different treatments than before the transformation and/or (3) patients' data obtained through clinical care are used, or used more extensively, for research purposes. Based on an analysis of the aforementioned mechanisms and how these potentially affect patients, we analyze why learning healthcare systems in precision medicine need a different ethical approach and discuss crucial points to consider regarding this approach.

"I Wish I Had Help Earlier. We Could Have Been Happier Sooner." Overcoming the Bystander Effect in the Care for Alcohol-Dependent Parents.

Parental alcohol dependency is associated with risks for the well-being of their children. However, guiding these families to support is often complicated. We interviewed 10 alcohol dependent parents, and held 3 focus group interviews with child welfare social workers, and alcohol and other drug workers. We identified a reluctance to act among professional and non-professional bystanders. Family members, neighbours, teachers, and general practitioners are often aware of parental drinking problems, but are reluctant to discuss them with the parents or to alert services designed to support families. The aim of this paper is to share the experiences of parents and show that parents appreciate interventions if done in a certain manner. Although parents were reluctant to discuss their drinking problem, they considered these problems as symptoms of underlying severe distress. They were highly motivated to get help for these underlying problems and wondered why they were not questioned about their distress by those around them. The silence of others reinforced pre-existing feelings of worthlessness and hopelessness. In this paper we analyse other's hesitation to intervene as a form of the bystander effect, and make suggestions on how this bystander effect can be overcome.

Mainstreaming informed consent for genomic sequencing: A call for action.

The wider availability of genomic sequencing, notably gene panels, in cancer care allows for personalised medicine or the tailoring of clinical management to the genetic characteristics of tumours. While the primary aim of mainstream genomic sequencing of cancer patients is therapy-focussed, genomic testing may yield three types of results beyond the answer to the clinical question: suspected germline mutations, variants of uncertain significance (VUS), and unsolicited findings pertaining to other conditions. Ideally, patients should be prepared beforehand for the clinical and psychosocial consequences of such findings, for themselves and for their family members, and be given the opportunity to autonomously decide whether or not to receive such unsolicited genomic information. When genomic tests are mainstreamed into cancer care, so should accompanying informed consent practices. This paper outlines what mainstream oncologists may learn from the ethical tradition of informed consent for genomic sequencing, as developed within clinical genetics. It argues that mainstream informed consent practices should focus on preparing patients for three types of unsolicited outcomes, briefly and effectively. Also, it argues that when the chance of unsolicited findings is very low, opt-out options need not be actively offered. The use of a layered approach - integrated in information systems - should render informed consent feasible for non-geneticist clinicians in mainstream settings. (Inter) national guidelines for mainstreaming informed consent for genomic sequencing must be developed.
