This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.
Chromosomal aneuploidies are linked with spontaneous miscarriages and abnormal offspring in human pregnancies. In addition, some types of aneuploidies are reported to prevent implantation. Thus, there is a need to identify the embryos with highest implantation potential on in vitro fertilization (IVF) programs. Since embryo morphology and kinetics have a weak association with embryo ploidy, trophectoderm biopsy plus Next-Generation Sequencing (NGS) is becoming a very popular approach to determine the embryo chromosomal status. This technique is called Preimplantation Genetic Testing for Aneuploidy (PGT-A). Although shown to be efficient, it is invasive for the embryo, requires specific technical skills and it remains expensive. Therefore, the development of a non-invasive, rapid and cheaper method for assessing embryo ploidy status would represent a progress in the field of IVF. The non-invasive approach has been explored by some groups that analyzed the Spent Blastocyst Medium (SBM) where the embryo was incubated up to the time of transfer or freezing. In daily routine, this media is discarded after finishing the culture of the embryo. Importantly, though, this media reportedly contains traces of embryonic cell-free DNA (cfDNA) that can represent the genetic load of the embryo. On the basis of that, the hypothesis of this study is that embryo prioritization according to the analysis of the embryonic cfDNA in the SBM could improve ongoing pregnancy rate in 10 percentual points compared to standard blastocyst transfer based on morphology.
Randomized Controlled Clinical Study to Assess the Benefit of Non-invasive PGT-A, by the Analysis of Spent Blastocyst Media, as a Tool for Embryo Prioritization in Infertile Patients Undergoing Assisted Reproduction.
Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.
