According to Norwegian law, an autonomous patient has the right to refuse life-prolonging treatment. If the patient is not defined as dying, however, health personnel are obliged to instigate life-saving treatment in an emergency situation even against the patient's wishes. The purpose of this study was to investigate how doctors' attitudes and knowledge agree with these legal provisions, and how the statutory provision on emergency situations influences the principle of patient autonomy for severely ill, but not dying, patients. ⋯ The answers indicate that the respondents include patients' refusal in an overall clinical judgement, and interpret patients' right to decline life-saving treatment in different ways. This may reflect the complex legal situation in Norway regarding patient autonomy with respect to the right of severely ill, but not dying, patients' right to decline acute life-saving treatment.

Infusion of bone marrow mesenchymal stem cells (MSCs) improves myocardial function following myocardial infarction (MI). The mechanisms, however, remain controversial. This study was to investigate changes of MSCs in vivo after administration into myocardial infarcted rats. Our hypothesis was that MSCs might differentiate into contractile myocytes and improve myocardial function in vivo. ⋯ MSCs can differentiate into beating cardiomyocytes in a rat model of MI and improve myocardial function.

Multicenter Study Comparative Study
Regional variations in early and late survival after out-of-hospital cardiac arrest.
While prior studies highlight regional variations in out-of-hospital cardiac arrest (OHCA) survival, the underlying reasons remain unknown. We sought to characterize regional variations early and later survival to hospital discharge after OHCA. ⋯ In this prospective multicenter North American series, there were regional disparities in early and later survival after OHCA, suggesting that there are underlying regional differences in out-of-hospital and post-arrest care beyond traditional Utstein predictors. Community efforts to improve OHCA survival must address both out-of-hospital and in-hospital care.
