Mrs. K is a thirty-one-year-old Russian-speaking mother of two, who was brought in by ambulance after attempting suicide by jumping in front of train. Probable depression x months. Stressor: lost custody battle over older child. Current status: deep coma, ventilator-dependent, and prognosis grim. Next of kin is estranged husband; he demands participation in medical decision making. Legal proxy is patient's boyfriend; forcibly removed from the intensive care unit (ICU) for agitated behavior and alcohol intoxication.

I magine the difficulty for the ICU staff as it tries to patch together the broken body of Mrs. K, described above. If, as appears likely, the physicians’ efforts begin to fail, who will speak for this patient, who can no longer speak for herself, and determine the appropriate goals and limits of intensive medical care?

The increase in the scope of international collaborative medical research involving human subjects is raising the problem of whether and how to maintain Western ethical standards when research is conducted in countries with very different social and ethical values. Existing international ethical guidelines for research largely reflect Western concepts of human rights, focusing on the bioethical principles of respect for persons, beneficence, and justice. However, in countries and societies where these values are understood differently or are not expressed in local cultures and institutions, it may be impossible or of no practical value to insert them into the research setting.

In the United States, individual informed consent is considered ethically imperative for research involving human subjects. However, this imperative may be difficult to instill in societies that define persons by their relations to others, and important decisions are commonly made by heads of households or group leaders rather than by individuals. The baseline economic and health care conditions in foreign communities may also create ethical conflicts.
