The Stanford Prison Experiment

The Stanford Prison Experiment

The famous and controversial Stanford Prison Experiment, conducted by social psychologist Philip Zimbardo and his colleagues at Stanford University, demonstrated the power of social roles, social norms, and scripts.

Robbers Cave

Robbers Cave

During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension could be...

Summary

This summary is machine-generated.

The Ross operation shows excellent long-term survival and low reoperation rates up to 13 years. Pulmonary autograft dilatation is a risk factor, while SDS-decellularized allografts offer promising RVOT reconstruction.

Background:

The Ross operation involves pulmonary autograft (PA) and right ventricular outflow tract (RVOT) allograft.
Long-term functional outcomes and risk factors for these components require evaluation.

Purpose of the Study:

To assess 13-year outcomes of the Ross operation.
Identify risk factors influencing late PA and RVOT allograft performance.

Main Methods:

Retrospective analysis of 272 patients undergoing the Ross operation (May 1995-March 2006).
Evaluation of PA root replacement and various RVOT allograft reconstructions (conventional, pericardial extension, deoxycholic acid, SDS decellularized).
Mean follow-up of 67 months (1,525 patient-years).

Main Results:

Hospital mortality 2.9%, 12-year late survival 93%.
12-year freedom from reoperation for PA and allograft was 97% and 95%, respectively.
PA dilatation risk factors: degenerative disease, large aortic annulus. SDS-decellularized RVOT allografts showed lower gradients.

Conclusions:

The Ross operation demonstrates excellent long-term survival and low reoperation rates up to 13 years.
Late PA dilatation and valvar insufficiency may necessitate future reoperations.
SDS-decellularized allografts represent a viable option for RVOT reconstruction.
