Is sleep quality , but not quantity , associated with self-perceived minor error rates among emergency department nurses?
Our study found that ED nurses' sleep quality, immediately prior to a working 12-hour shift, is more predictive of error than sleep quantity. These results present evidence that a "good night's sleep" prior to working a nursing shift in the ED is beneficial for reducing minor errors.
These results and our previous investigation in which 27.4% of IDC were positive for maspin suggest that the expression of maspin in epithelial cells could be up-regulated during the progression of ductal carcinoma, and that it could be correlated with the acquisition of an aggressive phenotype.
