Does a comparative roentgenographic analysis of the lumbar spine in male army recruit with and without lower back pain?
Given that radiographic screening shows that LBP is more common in those with spinal deformity it may be a reasonable means of predicting which individuals are more likely to develop LBP.
In this study we were unable to demonstrate a relationship between predialysis serum sodium and the dialysate sodium prescribed and changes in extracellular or intracellular fluid volumes. However this study showed that using a negative sodium gradient, patients can be successfully ultrafiltrated without setting up intracompartmental fluid gradients. The caveat is that the prescribed dialysate to serum sodium gradient may differ from the actual gradient.
