The Microbiome Meets Nanotechnology: Opportunities and Challenges in Developing New Diagnostic Devices.

Monitoring of the human microbiome is an emerging area of diagnostics for personalized medicine. Here, the potential of different nanomaterials and nanobiosensing technologies is reviewed for the development of novel diagnostic devices for the detection and measurement of microbiome-related biomarkers. Moreover, the current and future landscape of microbiome-based diagnostics is defined by exploring the advantages and disadvantages of current nanotechnology-based approaches, especially in the context of developing point-of-care (PoC) devices that would meet the international guidelines known as REASSURED (Real-time connectivity; Ease of specimen collection; Affordability; Sensitivity; Specificity; User-friendliness; Rapid & robust operation; Equipment-free; and Deliverability). Finally, the strategies of the latest international scientific consortia working in this field are analyzed, the current microbiome diagnostics market are reported and the principal ethical, legal, and societal issues related to microbiome R&D and innovation are discussed.

European perspectives on big data applied to health: The case of biobanks and human databases.

INTRODUCTION: The paradigm shift to a knowledge-based economy has incremented the use of personal information applied to health-related activities, such as biomedical research, innovation, and commercial initiatives. The convergence of science, technology, communication and data technologies has given rise to the application of big data to health; for example through eHealth, human databases and biobanks. METHODS: In light of these changes, we enquire about the value of personal data and its appropriate use. In order to illustrate the complex ground on which big data applied to health develops, we analyse the current situation of the European Union and two cases: the Catalan VISC+/PADRIS and the UK Biobank, as perspectives. DISCUSSION AND CONCLUSIONS: Personal health-related data in the context of the European Union is being increasingly used for big data projects under diverse schemes. There, public and private sectors participate distinctively or jointly, pursuing very different goals which may conflict with individual rights, notably privacy. Given that, this paper advocates for stopping the unjustified accumulation and commercialisation of personal data, protecting the interests of citizens and building appropriate frameworks to govern big data projects for health. A core tool for achieving such goals is to develop consent mechanisms which allow truly informed but adaptable consent, conjugated with the engagement of donors, participants and society.

[Review of the methodological, ethical, legal and social issues of research projects in healthcare with big data]. / Evaluación de los aspectos metodológicos, éticos, legales y sociales de proyectos de investigación en salud con datos masivos (big data).

The current model for reviewing research with human beings basically depends on decision-making processes within research ethics committees. These committees must be aware of the importance of the new digital paradigm based on the large-scale exploitation of datasets, including personal data on health. This article offers guidelines, with the application of the EU's General Data Protection Regulation, for the appropriate evaluation of projects that are based on the use of big data analytics in healthcare. The processes for gathering and using this data constitute a niche where current research is developed. In this context, the existing protocols for obtaining informed consent from participants are outdated, as they are based not only on the assumption that personal data are anonymized, but that they will continue to be so in the future. As a result, it is essential that research ethics committees take on new capabilities and revisit values such as privacy and freedom, updating protocols, methodologies and working procedures. This change in the work culture will provide legal security to the personnel involved in research, will make it possible to guarantee the protection of the privacy of the subjects of the data, and will permit orienting the exploitation of data to avoid the commodification of personal data in this era of deidentification, so that research meets actual social needs and not spurious or opportunistic interests disguised as research.

Gene Editing in Humans: Towards a Global and Inclusive Debate for Responsible Research.

In December 2016, the Opinion Group of the Bioethics and Law Observatory (OBD) of the University of Barcelona launched a Declaration on Bioethics and Gene Editing in Humans analyzing the use of genome editing techniques and their social, ethical, and legal implications through a multidisciplinary approach. It focuses on CRISPR/Cas9, a genome modification technique that enables researchers to edit specific sections of the DNA sequence of humans and other living beings. This technique has generated expectations and worries that deserve an interdisciplinary analysis and an informed social debate. The research work developed by the OBD presents a set of recommendations addressed to different stakeholders and aims at being a tool to learn more about CRISPR/Cas9 while finding an appropriate ethical and legal framework for this new technology. This article gathers and compares reports that have been published in Europe and the USA since the OBD Declaration. It aims at being a tool to foster a global and interdisciplinary discussion of this new genome editing technology.

[International regulation of ethics committees on biomedical research as protection mechanisms for people: analysis of the Additional Protocol to the Convention on Human Rights and Biomedicine, concerning Biomedical Research of the Council of Europe]. / Regulación internacional de los comités de ética en investigación biomédica como mecanismos de protección de las personas: Análisis del Protocolo Adicional sobre Investigación Biomédica al Convenio sobre Derechos Humanos y Biomedicina del Consejo de Europa.

The article explores and analyses the content of the Council of Europe's Additional Protocol to the Convention on Human Rights and Biomedicine concerning Biomedical Research regarding the standard legal instrument in biomedical research, issued by an international organization with leadership in bioethics. This implies ethics committees are mechanisms of protection of humans in biomedical research and not mere bureaucratic agencies and that a sound inescapable international regulatory framework exists for States to regulate biomedical research. The methodology used focuses on the analysis of the background, the context in which it is made and the nature and scope of the Protocol. It also identifies and analyses the characteristics and functions of ethics committees in biomedical research and, in particular, the information that should be provided to this bodies to develop their functions previously, during and at the end of research projects. This analysis will provide guidelines, suggestions and conclusions for the awareness and training of members of these committees in order to influence the daily practice. This paper may also be of interest to legal practitioners who work in different areas of biomedical research. From this practical perspective, the article examines the legal treatment of the Protocol to meet new challenges and classic issues in research: the treatment of human biological samples, the use of placebos, avoiding double standards, human vulnerability, undue influence and conflicts of interest, among others. Also, from a critical view, this work links the legal responses to develop work procedures that are required for an effective performance of the functions assigned of ethics committees in biomedical research. An existing international legal response that lacks doctrinal standards and provides little support should, however, serve as a guide and standard to develop actions that allow ethics committees -as key bodies for States- to advance in the protection of humans in biomedical research.

[Unresolved issues in the evaluation of research projects involving induced pluripotent stem cells (iPS)]. / Cuestiones no resueltas en la evaluación de los proyectos de investigación que involucran células madre de pluripotencia inducida (iPS).

This paper identifies problems and analyzes those conflicts posed by the evaluation of research projects involving the collection and use of human induced pluripotent stem cells (iPS) in Spain. Current legislation is causing problems of interpretation, circular and unnecessary referrals, legal uncertainty and undue delays. Actually, this situation may cause a lack of control and monitoring, and even some paralysis in regenerative medicine and cell therapy research, that is a priority nowadays. The analysis of the current legislation and its bioethical implications, led us to conclude that the review of iPS research projects cannot be assimilated to the evaluation of research projects that involve human embryonic stem cell (hESC). In this context, our proposal is based on the review by the Research Ethics Committees and the checkout by the Spanish Comission of Guarantees for Donation and Use of Human Cells and Tissues (CGDUCTH) of human iPS cells research projects. Moreover, this article claims for a more transparent research system, by effectively articulating the Registry on Research Projects. Finally, a model of verification protocol (checklist) for checking out biomedical research projects involving human iPS cells is suggested.
