Evaluating reliability and validity of the modified radiographic union scale for tibia (mRUST) among North American and Tanzanian surgeons.

Objectives: To determine the international reliability and validity of the modified Radiographic Union Scale for Tibial fracture (mRUST) scoring method for open tibial shaft fractures based on ratings of radiographs by separate groups of North American and Tanzanian surgeons.

Methods: Seven North American and 9 Tanzanian surgeons viewed 100 pairs of AP and lateral radiographs of open tibial shaft fractures obtained in Dar Es Salaam, Tanzania. The radiographs showed 25 patients' fractures at 4 time points postfracture after treatment with either external fixation or intramedullary nailing.

Psychological and neural responses to architectural interiors.

People spend considerable time within built environments. In this study, we tested two hypotheses about the relationship between people and built environments. First, aesthetic responses to architectural interiors reduce to a few key psychological dimensions that are sensitive to design features.
