AIMS: To determine the success threshold at which a theoretical course of deep brain stimulation (DBS) would provide the same quality of life (QoL) and cost-effectiveness for heroin dependence as methadone maintenance treatment (MMT). DESIGN: We constructed a decision analysis model to calculate QoL after 6 months of MMT and compared it to a theoretical course of DBS. We also performed a cost-effectiveness analysis using societal costs of heroin dependence, MMT and DBS. SETTING: Systematic literature review and meta-analysis. PARTICIPANTS: Patients (n = 1191) from 15 trials administering 6 months of MMT and patients (n = 2937) from 45 trials of DBS for movement disorders. MEASUREMENTS: Data on QoL before and after MMT, retention in MMT at 6 months, as well as complications of DBS and their impact on QoL in movement disorders. FINDINGS: We found a QoL of 0.633 (perfect health = 1) in heroin addicts initiating MMT. Sixty-six per cent of patients completed MMT, but only 47% of them had opiate-free urine samples, resulting in an average QoL of 0.7148 (0.3574 quality-adjusted life years (QALYs) over 6 months). A trial of DBS is less expensive ($81,000) than untreated (or relapsed) heroin dependence ($100,000), but more expensive than MMT ($58,000). A theoretical course of DBS would need a success rate of 36.5% to match MMT, but a success rate of 49% to be cost-effective. CONCLUSIONS: The success rate, defined as the percentage of patients remaining heroin-free after 6 months of treatment, at which deep brain stimulation would be similarly cost-effective in treating opiate addiction to methadone maintenance treatment, is estimated at 49%.

Evidence-based decision making (EBDM) is a tool to assess the value of medical interventions by weighing costs and health outcomes that has increasingly been applied to vaccines. However, many of the ethical considerations that support EBDM when used to evaluate therapeutic care do not readily translate to prevention. This mismatch can result in policy decisions that produce unanticipated negative consequences, including public resistance. In its emphasis on quantifiable outcomes, EBDM invokes the ethical principle of rule-utilitarianism, which values the optimal long-run balance of benefit over harm. Vaccines raise a number of competing ethical concerns in ways that individual medical treatments do not. They rely on widespread compliance for effectiveness, which can limit individual autonomy, emphasize population over individual effects, which can obscure the imperative of beneficence to help the vulnerable, require a just allocation process within populations, and sometimes challenge strong social norms. For EBDM to effectively guide vaccine policy makers, such as the Advisory Committee on Immunization Practices (ACIP) in the United States, an ethical foundation is needed that systematically considers all relevant values and transparently places vaccination recommendations in the context of social norms and individual concerns.

Caplan recalls his experience while attending a very unusual conference inside the Vatican City. The Pontifical Academy for Culture had convened a meeting to examine "ethical" ways to do stem cell research. Church leaders have made it clear time and again that they oppose the destruction of embryos as a way to get stem cells. It does not matter where the embryos come from; even if they are obtained from unwanted embryos at fertility clinics. Here, he observes that the church wants to find cures for a long list of awful diseases, but prelates face the prospect of a possible cure coming from ongoing embryonic stem-cell research that is taking place in many nations and some states in the US. A major point of the meeting this past November was to make it clear to the world that the Vatican recognizes the need to find cures. The meeting was called to illustrate a possible way forward via what the church has been convinced is the promising path of adult stem cells

The practice of transplanting organs from executed prisoners in China appears to be widespread. We vigorously condemn this practice and, effective immediately, will not consider manuscripts on human organ transplantation for publication unless appropriate non-coerced consent of the donor is provided and substantiated.

The movement to try to close the ever-widening gap between demand and supply of organs has recently arrived at the prison gate. While there is enthusiasm for using executed prisoners as sources of organs, there are both practical barriers and moral concerns that make it unlikely that proposals to use prisoners will or should gain traction. Prisoners are generally not healthy enough to be a safe source of organs, execution makes the procurement of viable organs difficult, and organ donation post-execution ties the medical profession too closely to the act of execution.
