Research using human tissues--a crisis of supply?

Brain donation procedures in the Sudden Death Brain Bank in Edinburgh

Brain banks typically receive donations through premortem consent procedures, often through disease-specific patient cohorts, such as dementia. While some control cases can be obtained through this route, access to age-matched control tissues, and some chronic neurologic conditions, particularly psychiatric disorders, can be challenging. The Edinburgh Sudden Death Brain Bank was established to try and increase access to control cases across all ages, and also access to psychiatric disorders through suicides. This chapter outlines the processes for establishing donations through medicolegal postmortems, which, although often with a prolonged postmortem interval, can provide high-quality well-characterized postmortem brain tissue to the neuroscience research community.

Consent to Donate Surgical Biospecimens for Research: Perceptions of People With Colorectal Cancer

BACKGROUND

Biospecimens for cancer research are commonly sought from people who undergo surgery for a new diagnosis of cancer, and the demand for these biospecimens is increasing.

OBJECTIVE

The objective of this study was to explore the perceptions of people with colorectal cancer regarding the impact of an opt-in model of consent for biospecimen donation.

METHODS

The qualitative method of Grounded Theory was used, and data were gathered through digitally recorded semistructured interviews with 18 participants. Data were analyzed using the constant comparative method to the descriptive level.

RESULTS

Four major categories were identified describing the response to the consent process used for donating tissue for research purposes. These were as follows: consent is "no big deal" compared with the diagnosis of cancer; helping others; trusting the surgeon; and information related to donation of biospecimens.

CONCLUSIONS

Results from this study indicate that the achievement of ideal informed and voluntary consent is difficult when patients are confronted with the trauma of newly diagnosed illness. Innovative approaches are implicated to obtain consent while protecting the autonomy and dignity of patients.

IMPLICATIONS FOR PRACTICE

The results from this study can contribute to further development of processes for the donation of biospecimens for research purposes that respect the needs and views of patients.

Standard Operating Procedures, ethical and legal regulations in BTB (Brain/Tissue/Bio) banking: what is still missing?

The use of human biological specimens in scientific research is the focus of current international public and professional concern and a major issue in bioethics in general. Brain/Tissue/Bio banks (BTB-banks) are a rapid developing sector; each of these banks acts locally as a steering unit for the establishment of the local Standard Operating Procedures (SOPs) and the legal regulations and ethical guidelines to be followed in the procurement and dissemination of research specimens. An appropriat Code of Conduct is crucial to a successful operation of the banks and the research application they handle. What are we still missing ? (1) Adequate funding for research BTB-banks. (2) Standard evaluation protocls for audit of BTB-bank performance. (3) Internationally accepted SOP's which will facilitate exchange and sharing of specimens and data with the scientific community. (4) Internationally accepted Code of Conduct. In the present paper we review the most pressing organizational, methodological, medico-legal and ethical issues involved in BTB-banking; funding, auditing, procurement, management/handling, dissemination and sharing of specimens, confidentiality and data protection, genetic testing, "financial gain" and safety measures. Taking into consideration the huge variety of the specimens stored in different repositories and the enormous differences in medico-legal systems and ethics regulations in different countries it is strongly recommend that the health-care systems and institutions who host BTB-Banks will put more efforts in getting adequate funding for the infrastructure and daily activities. The BTB-banks should define evaluation protocols, SOPs and their Code of Conduct. This in turn will enable the banks to share the collected specimens and data with the largest possible number of researchers and aim at a maximal scientific spin-off and advance in public health research.

Using human samples in proteomics-based drug development: bioethical aspects

Human samples and related medical data are expected to play an elevated role in application-based biomedical proteomics research. Against this framework, some facts should be kept in mind by academic and industrial researchers: international framework conditions on the use of human samples for research purposes are heterogeneous. For example, the value added by the use of human samples for product development is significant and the patient's personal and property rights may be affected. The body of national laws is growing and these laws are binding; guidelines published by international organizations should be respected. The most important aspect regards the informed consent of the patient, which is addressed in detail.

The importance of cultural considerations in the promotion of ethical research with human biologic material

Although ethical consideration has been given to a wide variety of issues that arise in the collection and storage of human biologic material for research, little attention has been focused on the ethical implications of the diverse cultural meanings often associated with these materials. We explore the rich social meanings of the placenta across cultures and contrast these meanings with the assumption that the placenta is typically considered waste tissue that may find value in biomedical research. We suggest that the incorporation of sensitivity to the cultural meanings people give human biologic material and the use of empirical research, where necessary, to delineate these meanings should enhance the ability to craft and conduct ethically appropriate research.
