RESUMO
Beta-aminopropionaldehyde is one of the serum aldehydes whose level increases on treating serum with As2O3 and methanol. In animal tissues, beta-aminopropionaldehyde can arise directly from the oxidation of spermidine or diaminopropane. A pathway linking spermidine, b-aminopropionaldehyde and malondialdehyde to the control of RNA and DNA synthesis is proposed (AU)

The "Uroscreen" as a screening test for significant bacteriuria has been assessed and shown to have an accuracy of 88.3 percent: there is a false positive rate of 56.6 percent of positive tests, or 14.4 percent of all tests, when compared with single plate cultures. All cases of significant bacteriuria associated with E.coli were detected by the "Uroscreen". It is recommended that the routine described be used. A urine screening test for significant bacteriuria has for the second time been assessed against the standard of significant bacteriuria; which in this series has been shown to have a confidence of 96 percent. It has been confirmed that routine screening for significant bacteriuria post partum is necessary, and appears most important in the primigravida. Post partum infection offers an explanation for the increase in prevalence of significant bacteriuria with parity. The figures confirm those of the University of the West Indies and indicate the prevalence of significant bacteriuria in the general pregnant population of Jamaica and the Caribbean may be similar to or higher than that found in series from other countries (AU)
