[Physician-assisted suicide - two perspectives]. / Ärztlich assistierter Suizid - zwei Perspektiven.

In February 2020, the Federal Constitutional Court of Germany issued a landmark judgement on assisted suicide. It rejected as unconstitutional a law from 2015 that prohibited "assisted suicide services". It emphasized the freedom of people to shape their own lives and deaths and to seek help in doing so. In contrast, other practical problems arise when a doctor is confronted with a request for assisted suicide at the bedside in the current situation. The different perspectives and their tensions are contrasted.

The Declaration of Helsinki in bioethics literature since the last revision in 2013.

The World Medical Association has announced that a new revision process of the Declaration of Helsinki has been started. This article will identify the criticisms that have been made in the bioethics literature, particularly since the last revision. In addition, criticisms are discussed that were made in the literature even before the last revision and have not fallen silent. The plausibility of the recommendation for a change in the Declaration of Helsinki is examined.

Kairos in diagnostics.

Kairos has been a key concept in medicine for millennia and is frequently understood as "the right time" in relation to treatment. In this study we scrutinize kairos in the context of diagnostics. This has become highly topical as technological developments have caused diagnostics to be performed ever earlier in the disease development. Detecting risk factors, precursors, and predictors of disease (in biomarkers, pre-disease, and pre-pre-disease) has resulted in too early diagnoses, i.e., overdiagnoses. Nonetheless, despite vast advances in science and technology, diagnoses also come too late. Accordingly, timing diagnostics right is crucial. In this article we start with giving a brief overview of the etymology and general use of the concepts of kairos and diagnosis. Then we delimit kairos in diagnostics by analysing "too early" and "too late" diagnosis and by scrutinizing various phases of diagnostics. This leads us to define kairos of diagnostics as the time when there is potential for sufficient information for making a diagnosis that is most helpful for the person. It allows us to conclude that kairos is as important in diagnostics as in therapeutics.

"That's just Future Medicine" - a qualitative study on users' experiences of symptom checker apps.

BACKGROUND: Symptom checker apps (SCAs) are mobile or online applications for lay people that usually have two main functions: symptom analysis and recommendations. SCAs ask users questions about their symptoms via a chatbot, give a list with possible causes, and provide a recommendation, such as seeing a physician. However, it is unclear whether the actual performance of a SCA corresponds to the users' experiences. This qualitative study investigates the subjective perspectives of SCA users to close the empirical gap identified in the literature and answers the following main research question: How do individuals (healthy users and patients) experience the usage of SCA, including their attitudes, expectations, motivations, and concerns regarding their SCA use? METHODS: A qualitative interview study was chosen to clarify the relatively unknown experience of SCA use. Semi-structured qualitative interviews with SCA users were carried out by two researchers in tandem via video call. Qualitative content analysis was selected as methodology for the data analysis. RESULTS: Fifteen interviews with SCA users were conducted and seven main categories identified: (1) Attitudes towards findings and recommendations, (2) Communication, (3) Contact with physicians, (4) Expectations (prior to use), (5) Motivations, (6) Risks, and (7) SCA-use for others. CONCLUSIONS: The aspects identified in the analysis emphasise the specific perspective of SCA users and, at the same time, the immense scope of different experiences. Moreover, the study reveals ethical issues, such as relational aspects, that are often overlooked in debates on mHealth. Both empirical and ethical research is more needed, as the awareness of the subjective experience of those affected is an essential component in the responsible development and implementation of health apps such as SCA.

The revised International Code of Medical Ethics: an exercise in international professional ethical self-regulation.

The World Medical Association (WMA), the global representation of the medical profession, first adopted the International Code of Medical Ethics (ICoME) in 1949 to outline the professional duties of physicians to patients, other physicians and health professionals, themselves and society as a whole. The ICoME recently underwent a major 4-year revision process, culminating in its unanimous adoption by the WMA General Assembly in October 2022 in Berlin. This article describes and discusses the ICoME, its revision process, the controversial and uncontroversial issues, and the broad consensus achieved among WMA constituent members, representing over 10 million physicians worldwide. The authors analyse the ICoME, including its response to contemporary changes and challenges like ethical plurality and globalisation, in light of ethical theories and approaches, reaching the conclusion that the document is a good example of international ethical professional self-regulation.

Ethical, Legal, and Social Implications of Symptom Checker Apps in Primary Health Care (CHECK.APP): Protocol for an Interdisciplinary Mixed Methods Study.

BACKGROUND: Symptom checker apps (SCAs) are accessible tools that provide early symptom assessment for users. The ethical, legal, and social implications of SCAs and their impact on the patient-physician relationship, the health care providers, and the health care system have sparsely been examined. This study protocol describes an approach to investigate the possible impacts and implications of SCAs on different levels of health care provision. It considers the perspectives of the users, nonusers, general practitioners (GPs), and health care experts. OBJECTIVE: We aim to assess a comprehensive overview of the use of SCAs and address problematic issues, if any. The primary outcomes of this study are empirically informed multi-perspective recommendations for different stakeholders on the ethical, legal, and social implications of SCAs. METHODS: Quantitative and qualitative methods will be used in several overlapping and interconnected study phases. In study phase 1, a comprehensive literature review will be conducted to assess the ethical, legal, social, and systemic impacts of SCAs. Study phase 2 comprises a survey that will be analyzed with a logistic regression. It aims to assess the user degree of SCAs in Germany as well as the predictors for SCA usage. Study phase 3 will investigate self-observational diaries and user interviews, which will be analyzed as integrated cases to assess user perspectives, usage pattern, and arising problems. Study phase 4 will comprise GP interviews to assess their experiences, perspectives, self-image, and concepts and will be analyzed with the basic procedure by Kruse. Moreover, interviews with health care experts will be conducted in study phase 3 and will be analyzed by using the reflexive thematical analysis approach of Braun and Clark. RESULTS: Study phase 1 will be completed in November 2021. We expect the results of study phase 2 in December 2021 and February 2022. In study phase 3, interviews are currently being conducted. The final study endpoint will be in February 2023. CONCLUSIONS: The possible ethical, legal, social, and systemic impacts of a widespread use of SCAs that affect stakeholders and stakeholder groups on different levels of health care will be identified. The proposed methodological approach provides a multifaceted and diverse empirical basis for a broad discussion on these implications.

The Judgment of the German Federal Constitutional Court regarding assisted suicide: a template for pluralistic states?

The article presents the judgment of the German Federal Constitutional Court from 26 February 2020 on assisted suicide. The statements regarding human dignity, human rights and the relationship between citizens and the state are examined. Furthermore, the consequences resulting from this interpretation of human dignity for states that are pluralistic and based on human rights will be laid out. The court's judgment limits the power of parliaments and poses a challenge to many laws in states that see themselves as pluralistic, human rights-based states.

Climate change and the different roles of physicians: a critical response to "A Planetary Health Pledge for Health Professionals in the Anthropocene".

The article critically responds to "A Planetary Health Pledge for Health Professionals in the Anthropocene" which was published by Wabnitz et al. in The Lancet in November 2020. It focuses on the different roles and responsibilities of a physician. The pledge is criticised because it neglects the different roles, gives no answers in case of conflicting goals, and contains numerous inconsistencies. The relationship between the Planetary Health Pledge and the Declaration of Geneva is examined. It is argued that the Planetary Health Pledge should have supplemented the Declaration of Geneva instead of changing it.

[Twin research in Germany]. / Medizinische Zwillingsforschung in Deutschland.

The worldwide development of twin cohorts began after World War II. These cohorts now include around 1.5 million twins, and more than 2748 twin studies have been published between 1950 and 2012. Each year, the number of twin publications increases by another 500 to 1000. The underrepresentation of German twin studies cannot be solely explained by the abuse of medical research under National Socialism. Developing and expanding large twin cohorts is a challenge in terms of both ethics and data protection. However, twin cohorts enable long-term and real-time research on many medical issues and contribute to answer the question of predisposition or environment as possible disease triggers - even after the sequencing of the human genome.There are currently two German twin cohorts: the biomedical cohort HealthTwiSt, with around 1500 pairs of twins, and TwinLife, a sociological-psychological cohort with around 4000 pairs of twins. There are also disease-specific cohorts. The TwinHealth Consortium in the Faculty of Medicine at the University of Tübingen was established in 2016 with the aim of enabling open-ended and sustainable twin research in Tübingen to answer various scientific questions.With the help of systematic literature research and medical history, this article gives an overview of the worldwide development of twin studies and databases over the last 100 years. The example of the Tübingen TwinHealth Initiative illuminates the structure of a twin cohort and its legal, ethical, and data protection aspects.

Placebo control in Covid-19 trials: A missed opportunity for international guidance.

Vaccines preventing Covid-19 have been approved in several countries. Is it still ethically acceptable to use placebo controls during the development of other vaccine options? If two of the most influential international guidelines of biomedical research are consulted, the Declaration of Helsinki and the CIOMS-guidelines, the answer is "no". We discuss the implications for ongoing vaccine research, and how placebo controls might be justified nevertheless. However, the ethical conflict remains highly problematic. We suggest that such ethical dilemmas should be avoided in the future by the introduction of a new system of global governance. Once vaccines are approved, a global regulation should oblige producers to provide the necessary amount of vaccine doses for the control groups of ongoing vaccine research.

Saving the most lives-A comparison of European triage guidelines in the context of the COVID-19 pandemic.

In March 2020, the rapid increase in severe COVID-19 cases overwhelmed the healthcare systems in several European countries. The capacities for artificial ventilation in intensive care units were too scarce to care for patients with acute respiratory disorder connected to the disease. Several professional associations published COVID-19 triage recommendations in an extremely short time: in 21 days between March 6 and March 27. In this article, we compare recommendations from five European countries, which combine medical and ethical reflections on this situation in some detail. Our aim is to provide a detailed overview on the ethical elements of the recommendations, the differences between them and their coherence. In more general terms we want to identify shortcomings in regard to a common European response to the current situation.

Short-term metreleptin treatment of patients with anorexia nervosa: rapid on-set of beneficial cognitive, emotional, and behavioral effects.

To examine the hypothesis that normalization of low circulating leptin levels in patients with anorexia nervosa ameliorates hyperactivity, three seriously ill females with hyperactivity were treated off-label with metreleptin (recombinant human leptin) for up to 14 days. Drive for activity, repetitive thoughts of food, inner restlessness, and weight phobia decreased in two patients. Surprisingly, depression improved rapidly in all patients. No serious adverse events occurred. Due to obvious limitations of uncontrolled case series, placebo-controlled clinical trials are mandatory to confirm the observed rapid onset of beneficial effects. Our findings suggest an important role of hypoleptinemia in the mental and behavioral phenotype of anorexia nervosa.

Living-Donor Uterus Transplantation: Pre-, Intra-, and Postoperative Parameters Relevant to Surgical Success, Pregnancy, and Obstetrics with Live Births.

Uterus transplantation (UTx) can provide a route to motherhood for women with Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS), a congenital disorder characterized by uterovaginal aplasia, but with functional ovaries. Based on our four successful living-donor transplantations and two resulting births, this analysis presents parameters relevant to standardizing recipient/donor selection, UTx surgery, and postoperative treatment, and their implementation in routine settings. We descriptively analyzed prospectively collected observational data from our four uterus recipients, all with MRKHS, their living donors, and the two newborns born to two recipients, including 1-year postnatal follow-ups. Analysis included only living-donor/recipient pairs with completed donor/recipient surgery. Two recipients, both requiring ovarian restimulation under immunosuppression after missed pregnancy loss in one case and no pregnancy in the other, each delivered a healthy boy by cesarean section. We conclude that parameters crucial to successful transplantation, pregnancy, and childbirth include careful selection of donor/recipient pairs, donor organ quality, meticulous surgical technique, a multidisciplinary team approach, and comprehensive follow-up. Surgery duration and blood vessel selection await further optimization, as do the choice and duration of immunosuppression, which are crucial to timing the first embryo transfer. Data need to be collected in an international registry due to the low prevalence of MRKHS.

The Hippocratic Oath and the Declaration of Geneva: legitimisation attempts of professional conduct.

The Hippocratic Oath and the Declaration of Geneva of the World Medical Association are compared in terms of content and origin. Their relevance for current medical practice is investigated. The status which is ascribed to these documents will be shown and the status which they can reasonably claim to have will be explored. Arguments in favor of the Hippocratic Oath that rely on historical stability or historical origin are being examined. It is demonstrated that they get caught up in paradoxes. Should doctors swear the Hippocratic Oath or the Declaration of Geneva? The Hippocratic Oath is a remarkable historic document, which contains important elements still relevant for medical ethics today. Its interpretation as a timeless, still valid medical code is unfounded. The historical arguments, that should justify its validity, are untenable. The Declaration of Geneva, and not the Hippocratic Oath, can legitimately claim to come close to representing the most important principles of professional medical conduct in today's globalised world.
