Are extremely preterm infants who small for gestational age have a high risk of early hypophosphatemia and hypokalemia?
Extremely preterm infants born SGA who were managed with currently recommended early parenteral nutrition had a high risk of early hypokalemia and hypophosphatemia. Potassium and phosphorus intakes should be set at sufficient levels from birth onwards, especially in SGA infants.
Mean protein intake to reach a neutral nitrogen balance in elderly hospitalized patients is 1.06+/-0.28 g/kg per day, which is higher than current recommendations for healthy elderly people. Safe protein intake (that would be adequate to ensure that 95% of patients remain in positive nitrogen balance) is difficult to establish.
