Clinical risk analysis with failure mode and effect analysis (FMEA) model in a dialysis unit.
The aim of clinical risk management is to improve the quality of care provided by health care organizations and to assure patients' safety. Failure mode and effect analysis (FMEA) is a tool employed for clinical risk reduction. We applied FMEA to chronic hemodialysis outpatients. ⋯ Employing FMEA, we worked on a few critical activities, and we reduced patients' clinical risk. A priority matrix also takes into account the weight of the control measures: we believe this evaluation is quick, because of simple priority selection, and that it decreases action times.

Biography Historical ArticleThe nature of water: Greek thought from Homer to Acusilaos.
Greek philosophy finds its roots in the myth of Homer's and Hesiod's poems and especially in Orphism which introduced the concept of a soul separated from the body with an independent principle, psiche (soul), to be rewarded or punished after death. Orphism was an important step in Greek culture. ⋯ From Orphism started the need of rituals capable of separating the spirit from the body. From Homer to Acusilaos, water was a very important element which connected humans and gods, long before Thales of Miletus defined it the arche.

Biography Historical ArticleThe nature of water: excerpts from Pythagoras, Xenophanes, Heraclitus and Parmenides.
Water was a prominent substance with Pythagoras, Xenophanes, Heraclitus and Parmenides, who flourished in the years 530-490 bc. The basic Pythagorean elements were earth and fire, and between them there were 2 intermediate entities (water and air), which were instrumental and indispensable components of specific solids. All things are a blend of different elements. ⋯ He built a dualist theory of the cosmos based on heat and cold, fire and earth - the former as a cause, the latter as substrate. The former unified, the latter separated. According to Aristotle, Parmenides considered air and water as mixtures of earth and fire.

Thales was born into a noble family of Phoenician origin at the time of the 25th Olympiad (floruit 585 bc; he was 40 in the year of the solar eclipse. He had no teachers but had occasion to learn from Egyptian priests. He developed into a scholar and politician very much appreciated by Heraclitus, Herodotus and Democritus, and was always considered a man of practical wisdom. ⋯ For Diogenes Laertius (Lives and Opinions of Eminent Philosophers), he was the instructor of Anaximander. Thales, the man who first discovered how to draw a right-angle triangle in a circle, was the first philosopher of nature (physis). "Philosophy begins with Thales," pointed out Bertrand Russell in 1961. This honor had been conceded also by Aristotle: "Anaximander, Thales' pupil, founded the Ionian tradition of philosophy." Many explanations may be given for the importance of water, including its importance for living processes, the economic role of the Nile, the importance of the port for Miletus and the fact that Ocean and Thetys were in Homer's tradition progenitors of the world.

The shortage of available deceased donors and the longer kidney transplant waiting lists in many countries around the world have placed greater emphasis on living donation (LD) as a means of meeting demand for transplantation in patients with end-stage kidney disease (ESKD). ⋯ If PKE were performed routinely using 2-way or 3-way PKE and altruistic donor chains, the rate of kidney transplants could increase by between 7% and 10%.
