Sliding down along the slippery slope

April 11, 2017

Pär SegerdahlDebates on euthanasia, abortion or embryonic stem cell research frequently invoke slippery slope arguments. Here is an example of such reasoning:

Legalizing physician-assisted suicide (PAS) at the end of life pushes healthcare morality in a dangerous direction. Soon, PAS may be practiced even on people who are not at the end of life and who do not request it. Even if this does not happen, the general population’s trust in healthcare will erode. Therefore, PAS must be forbidden.

Reasoning about the future is important. We need to assess consequences of allowing new practices. However, how do we assess the future in a credible way?

In an article in Medicine, Health Care and Philosophy, Gert Helgesson, Niels Lynøe and Niklas Juth argue that many slippery slope arguments are not empirically substantiated, but are based on value-impregnated factual assumptions. Anyone who considers PAS absolutely wrong considers it as a fatal step in a dangerous direction. Therefore, it is assumed that taking such a step will be followed by further steps in the same dangerous direction. If you chose the wrong path, you end up further and further away in the wrong direction. It seems inevitable that a first step is followed by a second step…

The problem is that this prophesying is based on the original moral interpretation. Anyone who is not convinced of the fatality of a “first” step does not have a tendency to see it as a “first step” with an inherent tendency to lead to a “second step” and finally to disaster.

Thinking in terms of the slippery slope can sometimes be experienced as if you yourself were on the slippery slope. Your thoughts slide toward the daunting precipice. Perhaps the article by Helgesson, Lynøe and Juth contains an analysis of this phenomenon. The slippery slope has become a vicious circle where the prophesying of disastrous consequences is steered by the moral interpretation that one defends with reference to the slippery slope.

Slippery slope arguments are not wrong in themselves. Sometimes development is on a slippery slope. However, this form of reasoning requires caution, for sometimes it is our thoughts that slide down along the slippery slope.

And that can have consequences.

Stem cells: unique biobank material?

March 7, 2017

Pär SegerdahlStem cells are perhaps not what first springs to mind as biobank material. Yet, even stem cells can be biobank material and there are biobanks that focus on stem cells. The use of this biobank material, however, has some unique features.

Stem cell researchers process not only data from human material. The material itself is “processed” and sometimes transplanted to research participants. Commercializing stem cell research moreover implies that cells derived from donated human tissue appear in products on a market. This gives rise to ethical and legal questions.

Does the law allow patenting cell lines derived from human donated material? Is buying and selling such material lawful? Another issue concerns research participants’ right to withdraw their consent at any time. Human embryonic stem cell research uses stem cells from donated spare embryos from IVF treatment. How far does embryo donors’ right to withdraw consent stretch? Must transplanted devices with matured cells be removed from research participants, if the embryo donor withdraws consent? Moreover, assuming that researchers share stem cell lines with companies, are these companies willing to invest in the development of stem cell products if embryo donors may withdraw their consent at any time?

Another difficulty is the purpose to which embryo donors are asked to consent. According to the law, human embryos can be donated only for research purposes (or to other IVF patients). Yet, medical research loses its meaning if results cannot be commercialized. It cannot then reach patients. It is important to inform donors about this broader context of embryo donation. Does that information imply that the consent becomes broader than has support in the law? Or is there support since embryos are not used in product development, only derived material?

The answers to these questions probably depend on whether one can distinguish between donated embryos and cell material derived from embryos (using various inventions). This raises also more philosophical questions about how to view embryos, stem cell lines, matured cells, and human tissue.

Stem cell therapy remains a form of treatment

February 27, 2017

Pär SegerdahlThere is a picture of stem cell therapy: It is in harmony with the body’s own way of functioning. Damaged tissue is regenerated as the body always regenerates tissue: through stem cells maturing into new body cells.

Patients can then hope for a body without a trace of disease: a healed body that takes care of itself as a healthy body does. It is almost as if we were not dealing a treatment at all, for the body restores itself, as it always does.

Stem cell therapy is certainly an important step towards effective treatment of several currently incurable diseases. The methods can also be said to be based on the body’s own way to regenerate tissue.

Nevertheless, I think we should emphasize that stem cell therapies are treatments next to others, with risks and benefits. Cells are transplanted into patients whose immune system can react. The implants may need to be checked regularly, or even be replaced. The transplantation can go wrong. And so on.

Stem cell therapy does not “transcend” all disease treatment hitherto by supporting the body’s own way of healing itself. We are still dealing with treatments of patients, rather than with “salvation from disease.”

Rhetoric of salvation is dangerous. It invites magicians and our faith in them. It justifies sacrifices to the benefit of Mankind. It disturbs our judgement.

Commercialization, but not at any price

February 14, 2017

Pär SegerdahlIn a previous post, I tried to make the point that the pharmaceutical industry can support altruism between research participants and patients, despite the fact that the industry itself is not altruistic but is driven by profit. Medical research will not benefit patients, unless results are developed into commercially available treatments.

However, this presupposes, of course, that pricing is reasonable, so that we can actually afford the drugs. Otherwise, research and research participation become meaningless.

Today, I just want to recommend an article in the journal Cell, where the authors argue that the prices of new cancer drugs have become indefensibly high. They propose new collaborations between academic researchers and small companies, to offer cancer drugs at more reasonable prices. Researchers should ensure that the companies they work together with are willing to sell the drugs with smaller profit margins.

You can find a summary of these ideas in The Guardian.

Not just facts, ideas are also needed

February 8, 2017

Pär SegerdahlWhen fraudulent “academic” journals publish articles without proper peer review. When websites online spread fake information. When politicians talk about alternative facts. Then undeniably, one feels a need for a general tightening up.

A possible problem in this reaction is that we castrate ourselves. That we don’t dare to propose and discuss ideas about the situation we are in. That we don’t dare to think, interpret and analyze. Because we fear being found guilty of error and of contributing to the scandalous inflation of facts and truths.

We hide ourselves in a gray armor of objectivity. In order not to resemble what we react to.

But why do these tendencies occur now? Is it about the internet? Is it about neglected groups of citizens? Is it about economic and political shifts in power?

In order to understand this complex situation and act wisely, we need not just facts but also good questions, thoughts, interpretations and analyses of the situation. If we take that task seriously, we also take relevant facts seriously when we discuss the ideas.

If we react with hypercorrection, with an armor of correctness, we risk repressing our questions about how we should think about our situation. We repress our uncertainty: the motive for thinking, interpreting and analyzing.

Ethics and law of stem cell treatment of diabetes

December 21, 2016

Pär SegerdahlMany people support in various ways medical research, which they perceive as urgent in view of the needs of various patient groups. But patients typically won’t benefit from research unless the results are translated into development of medical products.

Type 1 diabetes is an incurable disease that requires daily life-sustaining treatment and strict dietary rules. Disease onset usually occurs at an early age.

In Sweden, about 50 000 people have this form of diabetes and of these around 8 000 are children. In type 1 diabetes, the immune system attacks the insulin-producing cells. Without insulin the body cells cannot use glucose for energy, and the sugar level in the blood rises. Energy is recovered instead from fat and protein, which causes waste products that can cause diabetic coma and attacks on vital organs.

Today, diabetes is treated with daily insulin injections, or by using an insulin pump. This requires continuous measurement of blood sugar levels, as incorrect doses of insulin entails risks and can be life-threatening. It is not easy to live with diabetes.

An alternative treatment, which is still at the research stage, is to generate new insulin-producing cells using human embryonic stem cells. The insulin-producing cells detect blood sugar levels and regulate the secretion of insulin. In order not to be attacked by the immune system, the transplanted cells are encapsulated in a protective material. It may become easier to live with diabetes.

But research alone doesn’t treat diabetes. Encapsulated insulin-producing cells need to be produced and made available also to patients; not only to research participants. But this is a big step and a host of ethical and legal issues, including embryo donation, patentability and consent, need to be examined and discussed.

The Swedish Research Council recently granted funding for a project to examine these issues. The project is led by Mats G. Hansson at CRB and is a collaboration with Olle Korsgren, professor of transplantation immunology, as well as with lawyers Anna-Sara Lind and Bengt Domeij, and philosophers and ethicists Jessica Nihlén Fahlquist and Pär Segerdahl.

The step from stem cell research to available treatments requires reflection. I look forward to start thinking about the ethical and philosophical questions.

Research data, health cyberspace and direct-to-consumer genetic testing

December 14, 2016

josepine-fernow2We live in a global society, which means there are several actors that regulate both research and services directed at consumers. It is time again for our newsletter on current issues in biobank ethics and law. This time, Biobank Perspectives  lets you read about the legal aspects of direct-to-consumer genetic testing. Santa Slokenberga writes about her doctoral dissertation in law from Uppsala University and how the Council of Europe and the EU interact with each other and the legal systems in the member states. She believes direct-to-consumer genetic testing can be seen as a “test” of the European legal orders, showing us that there is need for formal cooperation and convergence as seemingly small matters can lead to large consequences.

We also follow up from a previous report on the General Data Protection Regulation in a Swedish perspective with more information about the Swedish Research Data Inquiry. We are also happy to announce that a group of researchers from the University of Oxford, University of Iceland, University of Oslo and the Centre for Research Ethics & Bioethics at Uppsala University received a Nordforsk grant to find solutions for governance of the “health cyberspace” that is emerging from assembling and using existing data for new purposes. To read more, download a pdf of the latest issue (4:2016), or visit the Biobank Perspectives site for more ethical and legal perspectives on biobank and registry research.
