A systematic review of studies evaluating diffusion and dissemination of selected cancer control interventions.

With this review, the authors sought to determine what strategies have been evaluated (including the outcomes assessed) to disseminate cancer control interventions that promote the uptake of behavior change. Five topic areas along the cancer care continuum (smoking cessation, healthy diet, mammography, cervical cancer screening, and control of cancer pain) were selected to be representative. A systematic review was conducted of primary studies evaluating dissemination of a cancer control intervention. Thirty-one studies were identified that evaluated dissemination strategies in the 5 topic areas. No strong evidence currently exists to recommend any one dissemination strategy as effective in promoting the uptake of cancer control interventions. The authors conclude that there is a strong need for more research into dissemination of cancer control interventions. Future research should consider methodological issues such as the most appropriate study design and outcomes to be evaluated.     

Experience with Euthanasia is Associated with Fearlessness about Death in Veterinary Students

Veterinarians have an increased risk for suicide compared with the general population, yet there is little consensus regarding why this might be. We hypothesized that veterinarians become relatively fearless about death due to their repeated exposure to euthanasia. Accordingly, we predicted that there would be a positive relationship between experience with euthanasia and fearlessness about death, due to emotional habituation to the process of euthanasia. In a sample of 130 veterinary students, results conformed to expectation and indicated that the relationship with fearlessness about death was specific to euthanasia and did not generalize to experience with surgery or necropsy.
