Four cases of squamous cell carcinoma arising from chronic pressure sores in paraplegic and tetraplegic patients are presented and the literature reviewed. These pressure-sore carcinomas are characterized by a shorter latency period and a fulminant clinical course with a very high metastatic rate. Very aggressive treatment including even hemicorporectomy must be considered if a cure is to be achieved. 相似文献

Testicular tissue cryopreservation (TTCP) aims to preserve the future option of genetic reproduction for prepubescent cancer patients who are at risk of infertility as a result of their cancer therapies. This technology is experimental and currently only offered in the research context. As TTCP moves towards becoming more widely available, it is imperative that healthcare providers recognize the complex ethical issues surrounding this technology. This scoping review study identifies and assesses the range and depth of ethical concerns related to this testicular tissue cryopreservation technology. At present, no such scoping review of ethical concerns exists in the TTCP literature. The forty-three full-text articles included in this study yielded twenty-two different ethical considerations discussed in relation to TTCP. It was observed that these ethical considerations fit within a mainstream Principlism approach to bioethics. Accordingly, there are ethical gaps in the TTCP literature that can be identified with alternative moral lenses. In particular, it was found that ethical concerns related to context and relational aspects of identity were absent in nearly all ethical examinations of TTCP. Furthermore, only 9 per cent of articles reviewed in this study focused primarily on the ethics of TTCP, thus demonstrating a need for further in depth ethical analyses of this technology. The results of this study are important for supporting the ethical provision of TTCP and can contribute to policy and guideline development. The findings of this study demonstrate the need for greater depth and diversity in analyses of ethical considerations related to this technology. 相似文献

How health care providers are paid affects how medicine is practiced. It is thus important to assess provider payment models not only from the economic perspective but also from the ethical perspective. China recently started to reform the provider payment model in the health care system from fee‐for‐service to case‐based payment. This paper aims to examine this transition from an ethical perspective. We collected empirical studies on the impact of case‐based payment in the Chinese health care system and applied a systematic ethical matrix that integrates clinical ethics and public health ethics to analyze the empirical findings. We identified eleven prominent ethical issues related to case‐based payment. Some ethical problems of case‐based payment in China are comparable to ethical problems of managed care and diagnosis related groups in high‐income countries. However, in this paper we discuss in greater detail four specific ethical issues in the Chinese context: professionalism, the patient‐physician relationship, access to care and patient autonomy. Based on the analysis, we cautiously infer that case‐based payment is currently more ethically acceptable than fee‐for‐service in the context of China, mainly because it seems to lower financial barriers to access care. Nonetheless, it will be difficult to justify the implementation of case‐based payment if no additional measures are taken to monitor and minimize its existing negative ethical implications. 相似文献

An American surgical team has announced its intention to perform the first human facial transplantation. The team has, however, invited further analysis of the ethical issues before it proceeds and in this paper we take up that challenge in seeking to frame the debate with a particular focus on the recipients of the transplant. We address seven related areas of concern and identify numerous questions that require answers or, perhaps, better answers. We start by examining the nature of the procedure and its intended benefits, why the procedure is being developed, and whether or not this should be viewed as experimental. Having concluded that this is experimental in nature, we then consider the broad question, who is the patient? Here we perceive difficulties in terms of the autonomy of the recipient, the unpredictable effects of receiving the transplant, and the role and influence of society. We conclude by asking whether the question should be 'whether or not?' rather than 'when?', particularly while the risks of losing face appear to far outweigh the likelihood of gaining face. 相似文献

We consider the implications for the ethical evaluation of research programs of two fundamental changes in the revised research ethical guideline of the Council for International Organizations of Medical Sciences. The first is the extension of scope that follows from exchanging “biomedical” for “health‐related” research, and the second is the new evaluative basis of “social value,” which implies new ethical requirements of research. We use the example of antibiotic resistance interventions to explore the need to consider the instances of what we term the pragmatic risks of such interventions to evaluate the social value of certain kinds of health‐related research. These (pragmatic) risks severely threaten the social value of interventions in every area where human and social responses significantly impact on their effectiveness. Thus, the social value of health‐related research needed to demonstrate its effectiveness depends on the extent and successful management of such risks. Research designed to take into account the management of pragmatic risks also gives rise to similar types of risks, and the potential for social value in light of those risks needs to be considered in ethical reviews based on the new guidelines. We argue that, to handle this new expanded task, the international system of research ethical review addressed by the guidelines needs institutional development. 相似文献

Transgender people have among the highest rates of suicide attempts of any group in society, driven strongly by the perception that they do not belong in the sex of their physical body. Gender reassignment surgery (GRS) is a procedure that can change the transgender person’s physical body to accord with their gender identity. The procedure raises important ethical and distributive justice concerns, given the controversy of whether it is a cosmetic or medical procedure and the economic costs associated with performing the procedure. This paper argues that there is a strong case for funding GRS as a matter of clinical necessity and justice. This paper will be divided in four key sections: First, the state of transgender health will be outlined, including the role of GRS and common objections to it. Second, a number of common objections to GRS will be analysed at the outset and shown to be unconvincing. Third, a constructive argument will be advanced, arguing that publicly funded GRS is clinically necessary, cost-effective, and demanded by principles of justice. Fourth, the paper will briefly discuss moralistic biases and why we demand a higher burden of justification for funding GRS compared with other analogous procedures. 相似文献

Despite more than 50 years of genetic research on Sámi people in Sweden, there has been very little engagement with the ethical issues related to this research. My aim is to investigate the ethical challenges in biobank research on Sámi people, to identify ethical challenges that have been overlooked and to find ethical solutions. In my historical research inquiry of published material and interviews with people that have participated in this research, my research questions have been: How are blood samples from Sámi people collected, codified, governed and analyzed? What ethical strategies have been utilized? My main findings are: Sweden acquired biobank collections from Sámi people that are not registered or cannot be traced through the biobank register at the Swedish National Board of Health and Welfare. These collections entail ethical challenges concerning how the donors are identified, how the material is categorized, the regional ethical committees, governance and Sámi representation. My suggestions focus on transparency and traceability, competence and native peoples' rights and representation in biobank-related activities. 相似文献

Hemicorporectomy is typically performed with a circumferential truncal incision, and the wound is closed primarily. Wound disruption is a common complication, especially at the base of the wound closure and posteriorly at the lumbar vertebral level. We report a case of the use of bilateral subtotal thigh flaps for the closure of a hemicorporectomy wound in a patient with a defect extending up to the high lumbar region. The subtotal thigh flap is a well-vascularized thick flap that provides a firm support for the abdominal viscera and is a large flap that can be used to close even a high lumbar defect. 相似文献

Inequities in global health are increasingly of interest to health care providers in developed countries. In response, many academic healthcare programs have begun to offer international service learning programs. Participants in these programs are motivated by ethical principles, but this type of work presents significant ethical challenges, and no formalized ethical guidelines for these activities exist. In this paper the ethical issues presented by international service learning programs are described and recommendations are made for how academic healthcare programs can carry out international service learning programs in a way that minimizes ethical conflicts and maximizes benefits for all stakeholders. Issues related to project sustainability and community involvement are emphasized. 相似文献

Controlled human infection challenge studies (CHIs) involve intentionally exposing research participants to, and/or thereby infecting them with, micro-organisms. There have been increased calls for more CHIs to be conducted in low- and middle-income countries (LMICs) where many relevant diseases are endemic. This article is based on a research project that identified and analyzed ethical and regulatory issues related to endemic LMIC CHIs via (a) a review of relevant literature and (b) qualitative interviews involving 45 scientists and ethicists with relevant expertise. In this article we argue that though there is an especially strong case for conducting CHIs in endemic (LMIC) settings, certain ethical issues related to the design and conduct of such studies (in such settings) nonetheless warrant particularly careful attention. We focus on ethical implications of endemic LMIC CHIs regarding (a) potential direct benefits for participants, (b) risks to participants, (c) third-party risks, (d) informed consent, (e) payment of participants, and (f) community engagement. We conclude that there is a strong ethical rationale to conduct (well-designed) CHIs in endemic LMICs, that certain ethical issues warrant particularly careful consideration, and that ethical analyses of endemic LMIC CHIs can inform current debates in research ethics more broadly. 相似文献

Cryopreservation of human embryos from the 2-cell stage up to the morula stage is a safe procedure which has been carried
out for the last 25 years. Experience with blastocyst cryopreservation is still limited and pregnancy rates after the use
of frozen, thawed blastocysts vary extremely. Vitrification has improved the success of embryo cryopreservation. However,
this technique cannot yet be considered as a routine procedure. Despite all of the advantages for infertile couples, cryopreservation
of human embryos creates severe ethical problems, because of surplus frozen embryos which either have to be destroyed or perhaps
used for research. Embryo adoption may provide a solution to solve imminent medical, ethical and social problems. 相似文献

Paternity testing in Italy is usually performed by private laboratories and universities having direct contacts with the applicants. Recently, the number of paternity tests offered through laboratory websites has increased in Italy and Europe. The execution of genetic tests, including paternity testing based on DNA analysis, represents a complex act, which contains three main steps. Paternity analyses carried out by laboratories via Internet are performed on samples collected by the applicants and then mailed back to the laboratories without any patient-physician relationship. Information is given to the subjects through the laboratory's website or mailed with the test order form. The execution of "household" DNA analysis without technical precautions may provide an incorrect response with severe consequences on the individual who has undergone testing, on the family involved, and on society in general. The problems connected with this kind of analysis are not technical, but ethical and deontological. In this work, we will discuss the problems related to information and consent by way of outlining the relevant Italian laws and codes of medical ethics. The Italian Privacy's Guarantor is assessing the ethical and legal implications, but regulations are not yet in place. We believe that adequate information related to this practice cannot be given via Internet, and, consequently, the validity of the consent expressed during this kind of procedure can be uncertain. Further, we will analyze issues regarding the importance of minors' protection when a paternity test is performed via Internet. In our opinion, the complexity of the situations and expectations linked to paternity investigations require a special sensitivity in dealing with each case, based on a patient-physician relationship in the decision-making process especially referring to the defense of the minors' well-being. 相似文献

Because the number of organs available for transplantation does not meet the needs of potential recipients, some have proposed that a potentially effective way to increase registration is to offer a self-benefit incentive that grants a 'preferred status' or some degree of prioritization to those who register as potential donors, in case they might need organs. This proposal has elicited an ethical debate on the appropriateness of such a benefit in the context of a life-saving medical procedure. In this paper we review arguments and ethical concerns raised by scholars, and studies of views of members of the public regarding the prioritization incentive system. We also report on our study of the views of those involved in organ transplant and of other medical professionals in Israel, as over half a decade ago Israel implemented a prioritization incentive system. Bioethicists propose that key stakeholders' views can provide additional arguments and perspectives on controversial issues. Proponents justify the prioritization incentive drawing mainly on arguments related to its potential effectiveness, reciprocity and fairness. Opponents point to the fact that registering is not binding and not an actual donation, and raise concerns regarding equity, autonomy and gaming the system. Ethical concerns raised by the practitioners in the study were examined in light of scholars' arguments and actual registration and donation data. Practitioners involved in transplantation raised ethical concerns corresponding to those raised by scholars as well as additional concerns. They also challenged proponents' assumptions regarding the utility of the incentive system from their own experience and argued that proponents obscure the meaning of reciprocity. 相似文献

Research with embryos and foetuses raise moral problems. In this article the origins of these moral intuitions are analyzed and discussed at four levels: moral problems regarding the treatment of the foetus and the mother animal; ethical problems experienced by the moral actor (researcher); ethical problems related to a justification based upon a balance between means and goals; and ethical problems raised by society. 相似文献

Totipotency, defined as the ability of a single cell to generate an entire individual, has traditionally served as a cornerstone to frame the moral relevance of nascent human life. This "potentiality principle" has served as an ethical reference point for shaping legal regulations for stem cell research in most Western countries. Based on heterogeneous ethical, religious, and political views, different countries cope with recent advances in mammalian cloning and reprogramming in a remarkably diverse manner. This and related issues were key topics at a recent meeting held in Berlin, Germany, on ethical aspects of stem cell research in Europe. An emerging view from this event is that international heterogeneity in stem cell politics and legislation must be overcome in order to develop this field toward biomedical application. 相似文献

This study investigated what information about brain death was available from Google searches for five major religions. A substantial body of supporting research examining online behaviors shows that information seekers use Google as their preferred search engine and usually limit their search to entries on the first page. For each of the five religions in this study, Google listings reveal ethical controversy about organ donation in the context of brain death. These results suggest that family members who go online to find information about organ donation in the context of brain death would find information about ethical controversy in the first page of Google listings. Organ procurement agencies claim that all major world religions approve of organ donation and do not address the ethical controversy about organ donation in the context of brain death that is readily available online. 相似文献

ObjectivesThe rapid development of cerebral organoid technology and the gradual maturity of cerebral organoids highlight the necessity of foresighted research on relevant ethical concerns. We employed knowledge graphs and conducted statistical analysis with CiteSpace for a comprehensive analysis of the status quo of the research on the ethical concerns of cerebral organoids from a bibliometric perspective.Materials and MethodsWe performed a statistical analysis of published papers on cerebral organoid ethics, keyword co‐occurrence graph, literature co‐citation and knowledge clustering graph to examine the status of the ethics research, internal relationship between technological development and ethical research, and ethical concerns of the academia. Finally, we used a keyword time zone graph and related statistics to analyze and predict the trends and popular topics of future cerebral organoids ethics research.ResultsWe demonstrated that although the ethical concerns of cerebral organoids have long been discussed, it was not until 2017 that the ethical issues began to receive more attention, when cerebral organoids were gradually mimicking the human brain more closely and increasingly being combined with chimera research. The recent key ethical concerns are primarily divided into three categories: concerns that are common in life sciences, specific to cerebral organoids, and present in cross‐fields. These increasing ethical concerns are inherently related to the continual development of technology. The analysis pointed out that future research should focus on the ethical concerns of consciousness that are unique to cerebral organoids, ethical concerns of cross‐fields, and construction and improvement of legislative and regulatory systems.ConclusionsAlthough research on cerebral organoids can benefit the biomedicine field, the relevant ethical concerns are significant and have received increasing attention, which are inherently related to the continual development of technology.

The introduction of novel diagnostic techniques in clinical domains such as genomics and radiology has led to a rich ethical debate on how to handle unsolicited findings that result from these innovations. Yet while unsolicited findings arise in both genomics and radiology, most of the relevant literature to date has tended to focus on only one of these domains. In this article, we synthesize and critically assess similarities and differences between “scanning the body” and “sequencing the genome” from an ethical perspective. After briefly describing the novel diagnostic contexts leading to unsolicited findings, we synthesize and reflect on six core ethical issues that relate to both specialties: terminology; benefits and risks; autonomy; disclosure of unsolicited findings to children; uncertainty; and filters and routine screening. We identify ethical rationales that pertain to both fields and may contribute to more ethically sound policies. Considerations of preserving public trust and ensuring that people perceive healthcare policies as fair also support the need for a combined debate. 相似文献

Human uterus transplantation (UTx) is currently under investigation as a treatment for uterine infertility. Without a uterus transplant, the options available to women with uterine infertility are adoption or surrogacy; only the latter has the potential for a genetically related child. UTx will offer recipients the chance of having their own pregnancy. This procedure occurs at the intersection of two ethically contentious areas: assisted reproductive technologies (ART) and organ transplantation. In relation to organ transplantation, UTx lies with composite tissue transplants such as face and limb grafts, and shares some of the ethical concerns raised by these non‐life saving procedures. In relation to ART, UTx represents one more avenue by which a woman may seek to meet her reproductive goals, and as with other ART procedures, raises questions about the limits of reproductive autonomy. This paper explores the ethical issues raised by UTx with a focus on the potential gap between women's desires and aspirations about pregnancy and the likely functional outcomes of successful UTx. 相似文献
