RESUMO
Currently, a prognostic biomarker-based model is being developed to predict the onset and disease progression of Huntington's Disease (HD) and Spinocerebellar Ataxia (SCA) types 1 and 3, both late-onset genetic neurodegenerative diseases lacking a disease-modifying treatment (DMT). The need for more accurate predictions of onset and disease progression arises in the context of clinical trials evaluating the effectiveness of potential DMTs and identifying the optimal time to initiate such a DMT. Moreover, such a prognostic model may provide mutation carriers with personal utility. The aim of this article is to anticipate the ethical issues raised by these new prognostic models and to formulate the ethical issues that need to be addressed to facilitate an ethically responsible development and implementation of such a model. Part one of this article describes the ethical issues raised by presymptomatic genetic testing for HD and evaluates whether and how these issues may also occur by predicting onset and disease progression. Part two presents the results of a critical interpretative review into the ethical issues raised by biomarker testing in other late-onset neurodegenerative diseases lacking a DMT. The review aims to identify new ethical issues related to biomarker testing for predicting the onset and disease progression of HD and SCA. Finally, based on parts one and two, part three proposes a research agenda for the near future regarding the most pressing ethical issues that need to be addressed to ensure an ethically responsible implementation of such a prognostic model in both research settings and clinical practice.
RESUMO
BACKGROUND: Counseling for whole-exome sequencing (WES) could benefit from aligning parents' pre- and post-disclosure attitudes. A few studies have qualitatively compared parents' pre- and post-disclosure attitudes toward receiving WES results for their child in a diagnostic setting. This study explored these attitudes in the context of children with a developmental delay. METHODS: Semi-structured interviews were conducted with parents (n = 27) of 16 children undergoing diagnostic WES in trio-analysis, both before and after receiving results. RESULTS: Three key insights emerged. First, the distinction between hoping and expecting was relevant for shaping parents' experiences with receiving results related to the primary indication. Second, parents of young children whose development of autonomous capacities was uncertain sometimes found themselves in a situation resembling a Catch-22 when confronted with decisions about unsolicited findings (UFs): an important reason for consenting to WES was to gain a better picture of how the child might develop, but in order to make responsible choices about UFs, some ideas of their child's development is needed. Third, default opt-ins and opt-outs helped parents fathom new kinds of considerations for accepting or declining UFs in different categories, thereby aiding decision-making. CONCLUSION: Results from this study are relevant for counseling and policy development.

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.

The next World Congress of Bioethics will be held in Doha, Qatar. Although this location provides opportunities to interact with a more culturally diverse audience, to advance dialogue between cultures and religions, offer opportunities for mutual learning, there are also huge moral concerns. Qatar is known for violations of human rights - including the treatment of migrant workers and the rights of women - corruption, criminalization of LGBTQI+ persons, and climate impact. Since these concerns are also key (bio)ethical concern we call for a broad debate within the bioethics community whether organizing and attending the World Congress in Qatar is ethically problematic and how ethical concerns should be dealt with.

Informed decision-making (IDM) is considered an important ethical and legal requirement for population-based screening. Governments offering such screening have a duty to enable invitees to make informed decisions regarding participation. Various views exist on how to define and measure IDM in different screening programmes. In this paper we first address the question which components should be part of IDM in the context of cancer screening. Departing from two diverging interpretations of the value of autonomy-as a right and as an ideal-we describe how this value is operationalized in the practice of informed consent in medicine and translate this to IDM in population-based cancer screening. Next, we specify components of IDM, which is voluntariness and the requirements of disclosure and understanding. We argue that whereas disclosure should contain all information considered relevant in order to enable authentic IDM, understanding of basic information is sufficient for a valid IDM. In the second part of the paper we apply the capability approach in order to argue for the responsibility of the government to warrant equal and real opportunities for invitees for IDM. We argue that additional conditions beyond mere provision of information are needed in order to do so.
RESUMO
New epigenomics technologies are being developed and used for the detection and prediction of various types of cancer. By allowing for timely intervention or preventive measures, epigenomics technologies show promise for public health, notably in population screening. In order to assess whether implementation of epigenomics technologies in population screening may be morally acceptable, it is important to understand - in an early stage of development - ethical and societal issues that may arise. We held 3 focus groups with experts in science and technology studies (STS) (n = 13) in the Netherlands, on 3 potential future applications of epigenomic technologies in screening programmes of increasing scope: cervical cancer, female cancers and 'global' cancer. On the basis of these discussions, this paper identifies ethical issues pertinent to epigenomics-based population screening, such as risk communication, trust and public acceptance; personal responsibility, stigmatisation and societal pressure, and data protection and data governance. It also points out how features of epigenomics (eg, modifiability) and changing concepts (eg, of cancer) may challenge the existing evaluative framework for screening programmes. This paper aims to anticipate and prepare for future ethical challenges when epigenomics technologies can be tested and introduced in public health settings.
RESUMO
In a previous study we found that parents of children with developmental delay (DD) favoured acceptance of unsolicited findings (UFs) for medically actionable conditions in childhood, but that preferences diverged for UFs with no medical actionability, or only in adulthood, and regarding carrier status. Sometimes the child's future autonomy formed a reason for withholding UFs for the present, despite an unfavourable prognosis concerning the child's cognitive capabilities. This might be different for children undergoing whole exome sequencing (WES) for reasons other than DD and who are expected to exert future autonomy. This is the focus of the current study. We conducted nine qualitative, semi-structured interviews with parents of children, ages <1-15, after consenting to WES, but prior to feedback of results, and with three adolescent children. Several parents wished to receive any information that might in whatever way be relevant to the health and well-being of their child, and to a lesser extent wished the inclusion of information about non-actionable disorders and information concerning carrier status of autosomal recessive disorders. Although parents understood the rationale behind the centre's UFs disclosure policy, they also felt that they needed this information in order to be able to exert their parental responsibility and take good care of a child still dependent on them. Parents reason from their notion of parental responsibility but are also inclined to take adolescent children's preferences seriously and acknowledge the child's incipient autonomy as a ground for granting an increasing degree of self-determination on the road to adulthood.

Epigenetic markers could potentially be used for risk assessment in risk-stratified population-based cancer screening programmes. Whereas current screening programmes generally aim to detect existing cancer, epigenetic markers could be used to provide risk estimates for not-yet-existing cancers. Epigenetic risk-predictive tests may thus allow for new opportunities for risk assessment for developing cancer in the future. Since epigenetic changes are presumed to be modifiable, preventive measures, such as lifestyle modification, could be used to reduce the risk of cancer. Moreover, epigenetic markers might be used to monitor the response to risk-reducing interventions. In this article, we address ethical concerns related to personal responsibility raised by epigenetic risk-predictive tests in cancer population screening. Will individuals increasingly be held responsible for their health, that is, will they be held accountable for bad health outcomes? Will they be blamed or subject to moral sanctions? We will illustrate these ethical concerns by means of a Europe-wide research programme that develops an epigenetic risk-predictive test for female cancers. Subsequently, we investigate when we can hold someone responsible for her actions. We argue that the standard conception of personal responsibility does not provide an appropriate framework to address these concerns. A different, prospective account of responsibility meets part of our concerns, that is, concerns about inequality of opportunities, but does not meet all our concerns about personal responsibility. We argue that even if someone is responsible on grounds of a negative and/or prospective account of responsibility, there may be moral and practical reasons to abstain from moral sanctions.
RESUMO
To date, few scholarly discussions on ethical implications of epigenetics and epigenomics technologies have focused on the current phase of research and development, in which researchers are confronted with real and practical ethical dilemmas. In this article, a responsible research and innovation approach, using interviews and an expert meeting, is applied to a case of epigenomic test development for cervical cancer screening. This article provides an overview of ethical issues presently facing epigenomics researchers and test developers, and discusses 3 sets of issues in depth: (1) informed consent; (2) communication with donors and/or research participants, and (3) privacy and publication of data and research results. Although these issues are familiar to research ethics, some aspects are new and most require reinterpretation in the context of epigenomics technologies. With this article, we aim to start a discussion of the practical ethical issues rising in research and development of epigenomic technologies and to offer guidance for researchers working in the field of epigenetic and epigenomic technology.
RESUMO
Information of an individual's epigenome can be useful in cancer screening to enable personalised decision making on participation, treatment options and further screening strategies. However, adding this information might result in complex risk predictions on multiple diseases, unsolicited findings and information on (past) environmental exposure and behaviour. This complicates informed consent procedures and may impede autonomous decision-making. In this article we investigate and identify the specific features of epigenetic risk-stratified cancer screening that challenge the current informed consent doctrine. Subsequently we describe current and new informed consent models and the principle of respect for autonomy and argue for a specific informed consent model for epigenetic risk-stratified screening programmes. Next, we propose a framework that guides the development of Patient Decision Aids (PDAs) to support informed consent and promote autonomous choices in the specific context of epigenetic cancer screening programmes.
RESUMO
BACKGROUND AND OBJECTIVE: Advances in omics open new opportunities for cancer risk prediction and risk-based screening interventions. However, implementation of risk prediction in clinical practice may impact the ethical, legal, and regulatory aspects of current cancer screening programs. In order to support decision-making, we analyzed the ethical, legal, and regulatory issues and developed a set of Points to Consider to support management of these issues. METHODS: We analyzed the legal and policy frameworks applicable to breast and cervical cancer screening programs in 7 European countries. We identified the most relevant issues to be considered, and we developed considerations for their management, based on the literature, the legal and policy frameworks, and our experience with similar issues. RESULTS: The considerations focus on five topics: (A) health services planning, (B) information and invitation, (C) consent and data/sample collection, (D) risk calculation and communication of results, and (E) storage of data and residual samples. CONCLUSION: Current frameworks might not be adequate to implement a risk prediction approach using omics factors due to the different characteristics of such approaches.

Research from behavioural sciences shows that people reach decisions in a much less rational and well-considered way than was often assumed. The doctrine of informed consent, which is an important ethical principle and legal requirement in medical practice, is being challenged by these insights into decision-making and real-world choice behaviour. This article discusses the implications of recent insights of research on decision-making behaviour for the informed consent doctrine. It concludes that there is a significant tension between the often non-rational choice behaviour and the traditional theory of informed consent. Responsible ways of dealing with or solving these problems are considered. To this end, patient decisions aids (PDAs) are discussed as suitable interventions to support autonomous decision-making. However, current PDAs demand certain improvements in order to protect and promote autonomous decision-making. Based on a conception of autonomy, we will argue which type of improvements are needed.

The incidence of cancer is continuing to rise and risk-tailored early diagnostic and/or primary prevention strategies are urgently required. The ideal risk-predictive test should: integrate the effects of both genetic and nongenetic factors and aim to capture these effects using an approach that is both biologically stable and technically reproducible; derive a score from easily accessible biological samples that acts as a surrogate for the organ in question; and enable the effectiveness of risk-reducing measures to be monitored. Substantial evidence has accumulated suggesting that the epigenome and, in particular, DNA methylation-based tests meet all of these requirements. However, the development and implementation of DNA methylation-based risk-prediction tests poses considerable challenges. In particular, the cell type specificity of DNA methylation and the extensive cellular heterogeneity of the easily accessible surrogate cells that might contain information relevant to less accessible tissues necessitates the use of novel methods in order to account for these confounding issues. Furthermore, the engagement of the scientific community with health-care professionals, policymakers and the public is required in order to identify and address the organizational, ethical, legal, social and economic challenges associated with the routine use of epigenetic testing.

Parents' preferences for unsolicited findings (UFs) from diagnostic whole-exome sequencing (WES) for their children remain largely unexplored. Our aim was to gain insight into parental considerations favoring acceptance/decline of UFs pertaining to their child. We conducted 20 qualitative, semistructured interviews with parents (n=34) of children with a developmental delay, aged <1 to 17 years, after consenting to WES, but before feedback of results. Key findings from our study were that all parents favored acceptance of UFs for medically actionable conditions in childhood, but that preferences and considerations diverged for UFs with no medical actionability, or only in adulthood, and regarding carrier-status. Sometimes non-medical utility considerations (considerations of usefulness of knowing UFs, not rooted in (preventive) medical treatment or controls) were given in favor of disclosure of UFs. Sometimes the child's future autonomy formed a reason to withhold UFs at present, despite an unfavorable prognosis concerning the child's cognitive capabilities. Some parents only preferred receiving UFs if these findings were directly related to their reasons for seeking a diagnosis. These findings are essential for developing morally responsible policy and for counseling. Further research should focus on whether considerations of non-medical utility alone can justify disclosure of UFs and whether reasons for seeking a diagnosis place further constraints on what UFs may be returned/withheld. How parents can be aided in contemplating different scenarios regarding their child's future development also deserves further inquiry.

In daily practice, pharmacists are regularly confronted with moral problems in which deciding what to do is not always a straightforward decision. In this contribution we show how the use of a specific method for moral deliberation can (in retrospect or prospective) aid moral judgements. We use the case of dispensing isotretinoin to demonstrate one ethical reflection method, namely the Utrecht Method.

Clinicians have to assess children's competence frequently. In order to do justice to children who are competent to make decisions and to protect incompetent children, valid assessment is essential. We address this issue by using bariatric surgery for morbidly obese minors as a case study. Our previous research indicated that opponents of bariatric surgery tend to be sceptical of the competence of adolescents to consent and inclined to set more stringent standards than proponents. Furthermore, there is the concern that minors wanting surgery are less able to make an autonomous decision than minors who do not wish to undergo surgery. Hence, few patients may be qualified as eligible. We argue for a risk-related standard, so that concerns are met, while at the same time preventing to set the bar too high, excluding paediatric patients who are most likely to benefit from surgery. This standard is also applicable in gastroenterology practice.

Despite the reported limited success of conventional treatments and growing evidence of the effectiveness of adult bariatric surgery, weight loss operations for (morbidly) obese children and adolescents are still considered to be controversial by health care professionals and lay people alike. This paper describes an explorative, qualitative study involving obesity specialists, morbidly obese adolescents, and parents and identifies attitudes and normative beliefs regarding pediatric bariatric surgery. Views on the etiology of obesity-whether it should be considered primarily a medical condition or more a psychosocial problem-seem to affect the specialists' normative opinions concerning the acceptability of bariatric procedures as a treatment option, the parents' feelings regarding both being able to influence their child's health and their child being able to control their own condition, and the adolescents' sense of competence and motivation for treatment. Moreover, parents and adolescents who saw obesity as something that they could influence themselves were more in favor of non-surgical treatment and vice versa. Conflicting attitudes and normative views-e.g., with regard to concepts of disease, personal influence on health, motivation, and the possibility of a careful informed consent procedure-play an important role in the acceptability of bariatric surgery for childhood obesity.

The Dutch Termination of Life on Request and Assisted Suicide Act [Wet toetsing levensbeëindiging op verzoek en hulp bij zelfdoding (Wtl)] came into force in 2002. Its aim is to increase the degree of due care exercised by physicians when terminating a patient's life and to provide a legal framework within which physicians account for their actions in such cases. On the basis of the second evaluation of the Act, published in December 2012, this article provides an overview of the most recent legal developments regarding the Dutch Euthanasia Act. Special attention is given to patients with dementia, psychiatric patients and patient who are "weary of life".
