Narrative Identity in Third Party Reproduction: Normative Aspects and Ethical Challenges

The legally charged issue of cross-border surrogacy: Current regulatory challenges and future prospects

The article aims to shed a light on the unique complexities inherent in surrogacy and the legal-ethical challenges that currently exists even in many advanced democracies, which frequently result in uneven and ill-defined standards and processes. The recent proposal of making surrogacy a "universal crime", meant to prevent cross-border surrogacy, i.e. travels by citizens from countries where it is illegal to countries where it is legal, has also been weighed, by exploring the current legislative state of affairs, trends and future horizons. Recent case-law has been analyzed and interpreted, with a close focus on Italian Supreme Court ruling n. 38162, issued on 30th December 2022 and European Court of Human Rights (ECtHR) rulings issued over the past decade. Uncertainty and ill-defined norms and court rulings risk harming the rights of children, surrogate mothers and intended parents. So far, court decisions have somehow filled the legal vacuum, considering that cross-border surrogacy is not specifically regulated in many countries and the status of children born abroad is still controversial. The views and judgments of supranational courts on the issue need to be accounted for when drafting new specific legislation. It is of utmost importance to uphold the rights of children born through surrogacy abroad, whose best interests risk being damaged. Legislative harmonization at the international level is essential to prevent the cross-border surrogacy trend. The "universal crime" draft bills appear to be difficult to enforce and too vague to be credible at the moment.

Role of Gut Microbiome in Cancer Treatment

The gut microbiota influences the effectiveness and side effects of cancer treatments, particularly immunotherapy and associated immune-related complications. This important involvement of the microbiome is supported by the patients receiving antibiotics responding poorly to immunotherapy. Relatively few research has examined the underlying processes, and until recently, data regarding the detection of the microbial organisms that trigger these effects were inconsistent. Since then, a deeper comprehension of the processes of action and taxonomic classification of the relevant species has been attained. It's been demonstrated that certain bacterial species can enhance the body's reaction to immune checkpoint inhibitors through the release of distinct metabolites or products. Nonetheless, in certain patients who are not responding, Gram-negative bacteria may have a dominating suppressive impact. Patients' propensity to react to immunotherapy can be somewhat accurately predicted by machine learning techniques based on their microbiome makeup. Consequently, there has been an increase in interest in modifying the microbiome makeup to enhance patient reaction to medication. Clinical proof-of-concept studies demonstrate that dietary modifications or fecal microbiota transplantation (FMT) might be used therapeutically to increase the efficacy of immunotherapy in cancer patients. Current developments and new approaches for microbiota-based cancer treatments have been emphasized. In conclusion, preclinical research on animals and human clinical trials has made tremendous progress in our understanding of the function of the gut microbiome in health and illness. These investigations have shed light on the effects of food, FMT, probiotics, prebiotics, and microbiome-disease connections. However, there are still a lot of issues and restrictions that must be resolved before this research can be used in real-world clinical settings.

Mapping Ethical, Legal, and Social Implications (ELSI) of gamete donation

RESEARCH QUESTION

This scoping review investigates the Ethical, Legal, and Social Implications (ELSI) of gamete donation, a critical facet of Assisted Reproductive Technologies, by analyzing the evolving research scope, methodological approaches, and the geographical skew in the literature. Despite the increased global uptake of donor gametes, current scholarship predominantly emanates from Western contexts and focuses on majoritized groups. This bias constrains the universality of research findings and limits their applicability across varied legal, cultural, and social contexts, underscoring a need for broader inclusivity.

DESIGN

We addressed 867 pivotal articles published between 1999 and 2019.

RESULTS

Our analysis reveals a discernible escalation in research volume, with 62% based on empirical research. The intellectual landscape unfolds into four dominant clusters: Regulatory Frameworks, Incentives, and Access; Family Dynamics and Genetic Linkages; Identity and Privacy in Donor Conception; and Cultural and Societal Attitudes towards GD. Each cluster highlights nuanced dimensions of gamete donation, from regulatory intricacies and psychological welfare to identity ethics and cultural perceptions.

CONCLUSION

Our findings advocate for a shift towards more globally representative and methodologically inclusive research. By integrating diverse cultural narratives and expanding geographical breadth, future research can offer holistic understandings of gamete donation, fostering equitable and culturally resonant practices and policies worldwide.

Circulating miRNAs as a Tool for Early Diagnosis of Endometrial Cancer-Implications for the Fertility-Sparing Process: Clinical, Biological, and Legal Aspects

This review article explores the possibility of developing an integrated approach to the management of the different needs of endometrial cancer (EC) patients seeking to become pregnant. Life preservation of the woman, health preservation of the baby, a precocious and-as much as possible-minimally invasive characterization of the health and fertility parameters of the patient, together with the concerns regarding the obstetric, neonatal, and adult health risks of the children conceived via assisted reproductive techniques (ART) are all essential aspects of the problem to be taken into consideration, yet the possibility to harmonize such needs through a concerted and integrated approach is still very challenging. This review aims to illustrate the main features of EC and how it affects the normal physiology of pre-menopausal women. We also focus on the prospect of a miR-based, molecular evaluation of patient health status, including both EC early diagnosis and staging and, similarly, the receptivity of the woman, discussing the possible evaluation of both aspects using a single specific panel of circulating miRs in the patient, thus allowing a relatively fast, non-invasive testing with a significantly reduced margin of error. Finally, the ethical and legal/regulatory aspects of such innovative techniques require not only a risk-benefit analysis; respect for patient autonomy and equitable health care access allocation are fundamental issues as well.

Shifting to a model of donor conception that entails a communication agreement among the parents, donor, and offspring

Background

Some persons conceived with donor gametes react negatively when they found their birth via donor conception. They request access to information about and seek to communicate with the donor. However, some countries mandate donor anonymity. Other countries allow donor-conceived persons to access donor information, but they can only use this access if their parents have disclosed donor conception to them. We investigated a thorny issue of donor conception: whether donor conception should be shifted from an anonymous basis to a non-anonymous basis.

Methods

We review the issues and concerns regarding donor conception. We then consider the impact of direct-to-consumer genetic testing on donor conception, as well as the influence of donor conception on offspring’s identity and the potential of different types of donors. To discuss the future policy of donor conception, the policies on the anonymity of gamete donors were investigated using publicly-available documents in 15 countries.

Results

The aim of mandating donor anonymity is to protect the privacy of the donor and intended parents. However, the diffusion of direct-to-consumer genetic testing may make it impossible to maintain anonymity. Birth via donor conception shapes the offspring’s identity, and the donor may further influence the development of offspring’s identity through communications. It remains important to disclose donor conception to donor-conceived offspring and to provide them with donor information. However, that information might be insufficient for some donor-conceived persons. Here are benefits to having open-identity donors and known donors. Such donors can make an agreement with the parents regarding future communication with the offspring, although both sides should respect privacy. Subsequent counseling for all parties involved can result in better tripartite communication agreements.

Conclusions

In sum, ethical and practical issues that complicate donor anonymity are driving a shift to non-anonymous donor conception, in which all parties come to a communication agreement. To pave the way for such a donor conception system, transitional measures can be put into place. For countries that already adopted non-anonymous donor conception, ensuring the communication agreements is important to protect the rights of parents, donor, and offspring.
