Medicolegal Death Investigation

Researchers often have a need to conduct human tissue research using postmortem specimens. Medicolegal death investigation organizations are untapped areas for obtaining postmortem human tissues. Because death investigation organizations are not required by law to conduct or support research, an ethical dilemma exists in whether or not researchers should use cadaver tissues for research purposes. This paper analyzes the ethical issues of using human tissues through discussion of principles of biomedical ethics, respect for autonomy, nonmaleficence, beneficence, and justice. Policy makers, organ and tissue procurement organizations, medicolegal death investigation organizations, and scientists should be aware of these principles when considering researchers requests. The authors conclude that with Institutional Review Board approval and next of kin consent, there are prevailing reasons for using postmortem tissue for research.

Tissue Procurement

Abstract Context.—Medical examiner cases are increasingly used as tissue donor referral sources to meet the ever-growing need for transplant tissues. The assumption is often made that traumatic and sudden deaths have minimal risk of unsuspected neoplasia. An autopsy of a registered tissue donor with strong preautopsy clinical assessment of a saddle pulmonary embolus revealed unsuspected acute lymphoblastic leukemia, prompting a review of the incidence of unsuspected neoplasia from a regional forensic autopsy practice. Objective.—To determine the incidence of (1) unsuspected neoplasia, (2) clinical concordance of known neoplasia, and (3) potential donor referral in a regional forensic autopsy service. Design.—A retrospective, 5-year review of 412 autopsies from a regional, primarily forensic, autopsy service to determine the incidence of unsuspected neoplasia, clinical concordance of known neoplasia, and the preautopsy assessment of potential donor referral suitability. Results.—Unsuspected neoplasia rate at autopsy was 7% (29 of 412 patients); cancer was the cause of death in 41% (12 of 29 patients) of these individuals. In patients with a history of cancer, the discordance of cancer diagnosis was 44% (4 of 9 patients [11 patients with known cancer, 2 who refused medical evaluation were excluded from the study]). Nearly 60% (17 of 29 patients) of the unsuspected cancer cases had no apparent reason for deferral of tissue procurement before the autopsy examination. Conclusions.—The 7% incidence of unsuspected cancer in a forensic autopsy practice raises concern for the potential introduction of neoplastic tissue in the donor pool. To ensure the safety of this vital resource, mandatory complete autopsies on deceased donors are advocated as well as a tissue-recipient registry to track donor-related neoplasia.

Bonding And Bridging

PurposeThe purpose of this paper is to examine the effect of social capital with bonding and bridging distinction in promoting higher participation in collective action in participatory irrigation management.Design/methodology/approachA sample of 304 farmers was surveyed using a structured questionnaire. A focus group discussion was also carried out with randomly selected water users, leaders and irrigation officers. A confirmatory factor analysis and structural equation modelling were used to test the hypothesised relationship of bonding and bridging social capital towards collective action.FindingsThe findings show that social capital has a significant direct effect on collective action and an indirect effect on joint irrigation management's perceived performance through collective action (mediator). It implies the need to complement the participatory irrigation management programme with an understanding of the social aspects for a higher farmer's participation over the shared resource.Originality/valueThe paper emphasises social capital's role in facilitating a real participatory engagement in shared resource management. Also, it is the first scholarly work linking social capital with bonding and bridging distinction towards collective action in a joint resource management context.
