Enjeux éthiques et légaux des applications du diagnostic préimplantatoire au Canada

Cousineau, Julie 01 1900 (has links)
Le diagnostic préimplantatoire (DPI), issu d'une alliance entre la procréation médicalement assistée et les techniques de diagnostic génétique, met à la disposition des êtres humains des conditions entièrement nouvelles pour le "contrôle de la qualité" des enfants. Sur la base d'un vaste ensemble de critères, telle choix du sexe ou l'élimination d'une maladie génétique, les parents peuvent désormais sélectionner leurs embryons créés par fécondation in vitro en fonction de leurs caractéristiques génétiques. Les applications du DPI suscitent toutefois de nombreuses questions. Pas surprenant que le DPI et ses différentes applications fassent l'objet d'un intense débat éthique; ils requièrent certes la mise en place d'un cadre normatif. En 2004, le Canada a finalement adopté la Loi concernant la procréation médicalement assistée et la recherche connexe (L.C. 2004, ch. 2). À titre de manipulation sur l'embryon, le DPI y est indirectement couvert. L'article 10 (2) établit en ce sens une condition générale concernant la modification, la manipulation, le traitement ou l'utilisation d'un embryon in vitro dont le régime de réglementation et d'autorisation en déterminera les limites. Nous pouvons à juste titre nous demander ce qu'il en sera dans le cas de chacune des applications du DPI. L'une d'entre elles, la sélection du sexe pour des raisons non médicales, est déjà prohibée en vertu du texte de loi. Que prévoiront les règlements pour les autres utilisations du DPI? Le gouverneur en conseil dispose du pouvoir pour désigner les catégories d'activités pouvant faire l'objet d'une autorisation ainsi que pour établir les modalités d'exercice de toute activité réglementée. De quelle nature seront ces règlements? Que doivent-ils ou peuvent-ils contenir? Je m'interroge sur le contrôle juridique des diverses applications de cette technique diagnostique. À cet égard, la France et le Royaume-Uni offrent des modèles normatifs fort intéressants pour le Canada. Au cours de cette analyse j'ai cherché à déterminer lequel de ces deux modèles est le plus adapté à la réalité canadienne en matière de procréation médicalement assistée et de DPI. J'ai d'autre part constaté que le choix d'un modèle dépend de notre position à l'égard de certaines questions éthiques telle l'importance de l'autonomie reproductive (i.e. la liberté de choix des embryons en fonction de critères établis par les individus). / Preimplantation genetic diagnosis (PGD), which results from an alliance between medically assisted reproduction and genetic diagnostic techniques, provides humans with an entirely new means of chiId "quality control." Based on a vast set of criteria, such as sex selection or the elimination of a genetic disorder, parents can now select embryos created via in vitro fertilization according to their genetic characteristics. These applications give rise to numerous questions. It is not surprising that PGD and its various applications are the subject of intense ethical debate; the implementation of a legislative framework is a definite necessity. ln 2004, Canada finally adopted the Act Respecting Assisted Human Reproduction and Related Research (S.C. 2004, ch. 2). PGD is indirectly covered under embryo manipulation. Section 10 (2) sets out general conditions concerning the modification, manipulation, treatment or use of an in vitro embryo-the limits of which are determined by the regulation and authorization framework. We may rightly ask what form this will take in each PGD application. One of them, sex selection for nonmedical reasons, is already prohibited in the text of the Act. What regulatory provisions will be made for other uses of PGD? The Governor-in-Council has the power to designate categories of activities that may be authorized and to establish conditions for the exercise of any regulated activity. What type of regulations will they be? What must they or should they contain? 1 have examined the judicial control of various applications of this diagnostic technique. Both France and the United Kingdom offer normative models of interest to Canada. During this analysis, 1 have endeavoured to determine which of these two models is most suited to the Canadian reality with respect to medically assisted reproduction and PGD. 1 thus noted that the choice of a model also depends on our position on certain ethical issues such as the importance of reproductive autonomy (i.e., freedom of choice of embryos according to criteria established by individuals). / "Mémoire présenté à la Faculté des études supérieures en vue de l'obtention du grade de LLM en maîtrise option recherche axe Droit, Biotechnologies et Société"

Preimplantation genetic diagnosis : new methods for the detection of genetic abnormalities in human preimplantation embryos

Konstantinidis, Michalis January 2013 (has links)
Preimplantation genetic diagnosis (PGD) refers to the testing of embryos produced through in vitro fertilization (IVF) in order to identify those unaffected by a specific genetic disorder or chromosomal abnormality. In this study, different methodologies were examined and developed for performance of PGD. Investigation of various whole genome amplification (WGA) methods identified multiple displacement amplification as a reliable method for genotyping single cells. Furthermore, this technology was shown to be compatible with subsequent analysis using single nucleotide polymorphism (SNP) microarrays. Compared to conventional methods used in this study to perform single cell diagnosis (e.g. multiplex PCR), WGA techniques were found to be advantageous since they streamline the development of PGD protocols for couples at high risk of transmitting an inherited disorder and simultaneously offer the possibility of comprehensive chromosome screening (CCS). This study also aimed to develop a widely applicable protocol for accurate typing of the human leukocyte antigen (HLA) region with the purpose of identifying embryos that will be HLA-identical to an existing sibling affected by a disorder that requires haematopoietic stem cell transplantation. Additionally, a novel microarray platform was developed that, apart from accurate CCS, was capable of reliably determining the relative quantity of mitochondrial DNA in polar bodies removed from oocytes and single cells biopsied from embryos. Mitochondria are known to play an important role in oogenesis and preimplantation embryogenesis and their measurement may therefore be of clinical relevance. Moreover, real-time PCR was used for development of protocols for CCS, DNA fingerprinting of sperm samples and embryos and the relative quantitation of telomere length in embryos (since shortened telomeres might be associated with reduced viability). As well as considering the role of genetics in terms of oocyte and embryo viability assessment and the diagnosis of inherited genetic disorders, attention was given to a specific gene (Phospholipase C zeta) of relevance to male infertility. A novel mutation affecting the function of the resulting protein was discovered highlighting the growing importance of DNA sequence variants in the diagnosis and treatment of infertility.

Kvalita života dětí s onemocněním spinální svalové atrofie / The quality of life of children suffering with spinal muscular atrophy

KOČOVÁ, Helena January 2014 (has links)
The scope of this dissertation focuses on issues related to the quality of life of children suffering with spinal muscular atrophy (SMA) and their carers and the associated social impact on families affected by this progressive and incurable disease. It describes ethical aspects of help to families with SMA and serious decisions in relation to the need to connect to artificial ventilation. Spinal Muscular Atrophy - SMA is a motoneuron disease i.e. disease of neurons, which are responsible for conscious movements of muscles e.g. running, head movement and swallowing. The prevalence is approximately 1 newborn for 6000 live births and approximately 1 person of 40 people is the carrier of the disease. SMA affects all the bone muscles i.e. proximal muscles are often affected the most. Everyone affected is in some point in life, depending on stage and type, reliant on mechanical or electrical wheelchair, in many cases also on artificial ventilation and permanent 24hr care. Families affected by this illness accept the fact of this progressive and incurable illness differently, this dissertation reflects upon such different perceptions on quality of life of the affected children, the carers. It forms a contribution in building a foundation for organising multi-discipline teams of experts with sole purpose of therapeutical interventions, to support the child and his/hers family. The World Health Organization (WHO) defines palliative care as "improving quality of life of patients facing life-threatening illnesses, and their families, through the prevention and relief of suffering by early identification and treatment of pain and other problems, whether physical, psychological, social or spiritual." Palliative care prepares families for these situations and should be provided along with whatever treatment options families choose. This dissertation is a comprehensive information base to support children affected by SMA and their families in early care in Czech Republic and in the process of inclusive educational integration into mainstream society.

Exorcising Intersex and Cripping Compulsory Dyadism

Orr, Celeste E. 08 May 2018 (has links)
Using hauntology as a linchpin, this dissertation explores the undertheorized connection between intersex and disability. Building on important feminist research in the fields of intersex, queer, disability, crip, and hauntology studies, I ask, how do we understand and reconcile the contested meanings, responses to, and effects of intersex? Intersex is “a perpetually shifting phantasm” (Holmes 2002: 175), yet intersex is typically represented and treated as innate disorder, disability, or disease by medical professionals. That said, many intersex people appear to distance from disability. By engaging intersex studies with feminist disability and crip theories, however, I demonstrate that an intersex politic and intersex studies must be rooted in a disability politic and disability studies. Through a feminist disability and crip lens, I conduct a textual and critical discourse analysis of three case studies of interphobic violence or, what I term, “compulsory dyadism,” meaning the instituted cultural mandate that people cannot have intersex traits or house the “spectre of intersex” (Sparrow 2013: 29); such a spectre must be exorcised. The three case studies include nonconsensual medical interventions, sport sex testing, and employing reproductive technologies to select against intersex variations. My analyses of these case studies produce three important observations. First, intersex is presently and effectively being integrated into conventional notions of disability; second, ableist logics underpin interphobic violence; and third, compulsory dyadism is intertwined with, or is an iteration of, compulsory able-bodiedness. In recognizing this interconnection, theorizing intersex and disability together is not merely beneficial, doing so is necessary. Ultimately, my dissertation interrogates and extends questions of the ever-shifting categorization of body-minds, culturally mandated ways of being, and (the haunting effects of) pathologization. I apply pressure to the academic field of intersex studies as well as intersex activist and advocate communities to center disability in discussions concerning intersex human rights and interphobia.
