However, the potential pathway from restricted work ability to ERI must also be considered. Therefore, the aim of our study was to analyse cross-sectional and longitudinal associations between ERI and work ability and vice versa. METHODS Data come from the Second German S...

Nutrition and fluid and electrolyte balance are inextricably linked through ingestion, digestion, absorption and intermediary metabolism. Studies are described showing that man's physiological capacity to excrete excess salt and water is limited under normal conditions; it is further reduced by starvation and injury, so that patients are easily overloaded, resulting in increased complications o...
