In summary, physician managers have a bright future. They are working on one of the most exciting professional interfaces--medicine and management. The future of medicine is both high-tech and low-tech. It will challenge all physician executives. For a few years, health care organizations will experience turbulence and stress. The name of the game for physician managers will be organizational survival. The nation will then move into an era of abundance in medical care, and the management game will switch from survival to thrival. Managers are key players in the world of tomorrow. The physician executive is a manager and therefore a key player. One of the best things about the future of the physician is that he has one.

The physician executive in a changing world.

Physicians are losing their historic franchise as sole and primary providers of medical care. In addition to eroding moral and scientific authority, physicians are also losing income and status. It is no wonder that physicians are retrenching--confused and angry about the increasing marginalization of their profession and about society's changing expectations. Physicians are caught in a transition zone between the world that was and the one that will soon be. This is destabilizing and causes great anxiety. Rather than being buffeted by changing social and cultural definitions of health care, physicians must become proactively involved in the future of their profession. Physicians can only do this by offering a better mental model of health, medicine, and the community. This cannot be a defensive retreat from engagement. Rather, it must be an imaginative vision, vigorously set forth--a vision that will enlist the support of all constituencies involved in the effort to improve the health and well-being of all members of our society. The physician executive needs to work with physicians to orchestrate this effort to create a new vision of health in the 21st century.

Spirituality and the physician executive.

The "s" word can now be spoken without flinching in health care organizations. Spirituality is becoming a common topic in management conferences around the world. Many U.S. corporations are recognizing the role of spirituality in creating a new humanistic capitalism that manages beyond the bottom line. Spirituality refers to a broad set of principles that transcend all religions. It is the relationship between yourself and something larger, such as the good of your patient or the welfare of the community. Spirituality means being in right relationship to all that is and understanding the mutual interdependence of all living beings. Physician executives should be primary proponents of spirituality in their organizations by: Modeling the power of spirituality in their own lives; integrating spiritual methodologies into clinical practice; fostering an integrative approach to patient care; encouraging the organization to tithe its profits for unmet community health needs; supporting collaborative efforts to improve the health of the community; and creating healing environments.

The effect of promoter strength in adenoviral vectors containing herpes simplex virus thymidine kinase on cancer gene therapy in vitro and in vivo.

The use of adenoviral vectors to deliver the herpes simplex virus thymidine kinase (HSVtk) gene followed by treatment with the prodrug ganciclovir (GCV) has promise for a variety of applications where excess cell proliferation is detrimental such as treatment of tumors and vascular restenosis. Optimizing this system is thus an important goal. The purpose of this study was to determine if the induction of higher levels of HSVtk expression would augment the sensitivity to GCV. This was accomplished by generating adenoviral vectors that expressed HSVtk from promoters of different efficiencies (the CMV versus RSV promoters). Despite higher levels of HSVtk expression per cell with the CMV promoter, there was no significant enhancement of antitumor effects between RSV- and CMV-driven adenovirus vectors in in vitro and in vivo studies indicating that simply increasing HSVtk enzyme levels per cell above a minimal threshold level will not be effective in augmenting the HSVtk/GCV system. These results suggest that other strategies, e.g., the use of higher doses of GCV, augmentation of the "bystander effect," the generation of mutant HSVtk genes with higher substrate affinities, the discovery of improved vectors with increased transduction efficiencies, or the development of new prodrugs with higher affinities for HSVtk will therefore be needed to enhance therapeutic responses.
