Stanford's Biodesign Innovation program: Teaching opportunities for value-driven innovation in surgery.

The Stanford Biodesign Innovation process, which identifies meaningful clinical needs, develops solutions to meet those needs, and plans for subsequent implementation in clinical practice, is an effective training approach for new generations of healthcare innovators. Continued success of this process hinges on its evolution in response to changes in healthcare delivery and an ever-increasing demand for economically viable solutions. In this article, we provide perspective on opportunities for value-driven innovation in surgery and relate these to value-related teaching elements currently integrated in the Stanford Biodesign process.

The Impact of Postgraduate Health Technology Innovation Training: Outcomes of the Stanford Biodesign Fellowship.

Stanford Biodesign launched its Innovation Fellowship in 2001 as a first-of-its kind postgraduate training experience for teaching biomedical technology innovators a need-driven process for developing medical technologies and delivering them to patients. Since then, many design-oriented educational programs have been initiated, yet the impact of this type of training remains poorly understood. This study measures the career focus, leadership trajectory, and productivity of 114 Biodesign Innovation Fellowship alumni based on survey data and public career information.

DAP10 deficiency breaks the immune tolerance against transplantable syngeneic melanoma.

DAP10, an activating adaptor protein, associates with the NKG2D protein to form a multisubunit receptor complex that is expressed in lymphoid and myeloid cells. The ligands for NKG2D-DAP10 receptor are expressed in both normal and tumor cells, suggesting distinct roles for this receptor in autoimmunity and cancer. In this study, we report that constitutive DAP10 activating signaling is part of regulatory mechanisms that control immunity against tumors.

IL-23 stimulates epidermal hyperplasia via TNF and IL-20R2-dependent mechanisms with implications for psoriasis pathogenesis.

Aberrant cytokine expression has been proposed as an underlying cause of psoriasis, although it is unclear which cytokines play critical roles. Interleukin (IL)-23 is expressed in human psoriasis and may be a master regulator cytokine. Direct intradermal administration of IL-23 in mouse skin, but not IL-12, initiates a tumor necrosis factor-dependent, but IL-17A-independent, cascade of events resulting in erythema, mixed dermal infiltrate, and epidermal hyperplasia associated with parakeratosis.
