Acute kidney injury (AKI) is a common complication in critically ill patients with an incidence of up to 50% in intensive care patients. The mortality of patients with AKI requiring dialysis in the intensive care unit is up to 50%, especially in the context of sepsis. Different approaches have been undertaken to reduce this high mortality by changing modalities and techniques of renal replacement therapy: an early versus a late start of dialysis, high versus low dialysate flows, intermittent versus continuous dialysis, anticoagulation with citrate or heparin, the use of adsorber or special filters in case of sepsis. Although in smaller studies some of these approaches seemed to have a positive impact on the reduction of mortality, in larger studies these effects could not been reproduced. This raises the question of whether there exists any impact of renal replacement therapy on mortality in critically ill patients—beyond an undeniable impact on uremia, hyperkalemia and/or hypervolemia. Indeed, this is one of the essential challenges of a nephrologist within an interdisciplinary intensive care team: according to the individual situation of a critically ill patient the main indication of dialysis has to be identified and all parameters of dialysis have to be individually chosen with respect to the patient’s situation and targeting the main dialysis indication. Such an interdisciplinary and individual approach would probably be able to reduce mortality in critically ill patients with dialysis requiring AKI.

Commercial salmon farming in the Maritimes shows potential as a source of rural employment, growth, and foreign exchange. Canada lags behind most advanced countries in developing its aquaculture industry; Atlantic salmon (Salmo salar) might be one species in which Canada has a comparative advantage and in which Canada's late start might be overcome. This paper evaluates sea pen salmon culture by a number of criteria, including financial feasibility, and concludes that salmon farming can be profitable, contribute to growth, absorb labour, and earn foreign exchange. A final section explores policy options available to governments and to private sector producers.

Grottenolme Proteus anguinus (Laurenti, 1768) zeigen eine sehr geringe Fortpflanzungsrate, werden sehr alt und haben eine im Vergleich zum Menschen verzögerte Generationenfolge. Damit sind Olme Lebewesen für spannende evolutionsbiologische Fragestellungen, die sich um Populationswachstum drehen. Die vorliegende Arbeit zeigt auf, dass eine stabile Umwelt, wenig Krankheiten, das Fehlen von Fressfeinden und ausreichende Nahrungsressourcen evolutiv einen starken Einfluss auf das fehlende Populationswachstum beim Olm haben. Ein Vergleich mit dem Menschen eröffnet, neben der Bildung und dem Aufbrechen von Bräuchen, auch Wege naturgegebener Mechanismen, wie das Wachstum der Weltbevölkerung sich stabilisieren ließe. Der verzögerte Eintritt in die Reproduktion zeigt beim Grottenolm zudem einen positiven Effekt auf die Langlebigkeit. Human fish and human beings – European Cave Salamander Proteus anguinus (Laurenti, 1768) explains longevity and population growth Abstract: European Cave Salamanders, more specifically olms, show a low reproduction rate, reach methuselah ages and exhibit extended generation frequencies in comparison to humans. Olms are therefore considered an interesting study object for evolutionary questions about population growth. The paper discusses stable environment, good health, top predator position and continuous basic food supply as the key factors for stagnation of population growth in olms as well, if combined with education, as in humans. A late start of reproduction triggers in turn a positive impact on longevity.
