Ética y muerte digna

This book is an study about the bill of Death with Dignity Act, written by the Andalusian Commission on Healthcare Ethics and Research. The aim of the Act would be to “establish the criteria and conditions to be adopted by the health system to guarantee adequate healthcare during life’s final process based on the prevention of suffering and respect for each person’s dignity and free choice”.

Ética y muerte digna, historia de una ley : El proceso de regulación jurídica de la atención sanitaria al final de la vida en Andalucía (España)

End-of-life healthcare in any part of the world is always rife with ethical conflicts and legal challenges. In this matter, the opinions and preferences of patients, family members, healthcare professionals, society as a whole and politicians may differ or diverge entirely1. Nevertheless, death comes to all eventually; it is part of human life itself. The fact remains that we will all die. Therefore, it is natural for all societies to seek the necessary consensus for guaranteeing that individuals can live, and die, in a way befitting their nature, i.e., humanely and with full dignity. This article tells the story of how the citizens of Andalusia, in the south of Spain, reached this majority consensus during the process of drafting and approving a law regulating this issue: Law 2/2010, of 8 April, on personal rights and guarantees to die in dignity.

Role of fibronectin in the adhesion of Acinetobacter baumannii to host cells.

Adhesion to host cells is an initial and important step in Acinetobacter baumannii pathogenesis. However, there is relatively little information on the mechanisms by which A. baumannii binds to and interacts with host cells. Adherence to extracellular matrix proteins, such as fibronectin, affords pathogens with a mechanism to invade epithelial cells. Here, we found that A. baumannii adheres more avidly to immobilized fibronectin than to control protein. Free fibronectin used as a competitor resulted in dose-dependent decreased binding of A. baumannii to fibronectin. Three outer membrane preparations (OMPs) were identified as fibronectin binding proteins (FBPs): OMPA, TonB-dependent copper receptor, and 34 kDa OMP. Moreover, we demonstrated that fibronectin inhibition and neutralization by specific antibody prevented significantly the adhesion of A. baumannii to human lung epithelial cells (A549 cells). Similarly, A. baumannii OMPA neutralization by specific antibody decreased significantly the adhesion of A. baumannii to A549 cells. These data indicate that FBPs are key adhesins that mediate binding of A. baumannii to human lung epithelial cells through interaction with fibronectin on the surface of these host cells.
