The study assessed the adequacy of nutrition support in critically ill infants and children and identifies barriers impeding the delivery of estimated energy requirement (EER). ⋯ This study highlights the inadequacy of nutrition support in critically ill children in the PICU. Restriction of fluid intake was the main barrier to the delivery of adequate nutrition, particularly in infants undergoing cardiac surgery.

Comparative Study
Validity and accuracy of regional bioelectrical impedance devices to determine whole-body fatness.
Growing emphasis on obesity as a risk factor for chronic diseases and commercial availability of impedance devices for the at-home assessment of body fatness have stimulated the need for a critical evaluation of the validity of these instruments. This study determined the reproducibility and accuracy of two commercial impedance devices that use upper (hand-to-hand) or lower (foot-to-foot) body contact electrode placements in adults with a wide range of body fatness. ⋯ Use of regional impedance devices to assess body fatness is limited by a lack of precision and accuracy.

Comparative Study
Comparison of bioelectrical impedance prediction equations for fat-free mass in a population-based sample of 75 y olds: the NORA study.
We evaluated the performance of different prediction equations to estimate fat-free mass (FFM) from bioelectrical impedance analysis (BIA) in the elderly. ⋯ Different prediction equations produced different values for FFM. The age-specific equations developed in other populations underestimated FFM, whereas FFM(GEN) produced an unbiased estimate of FFM in males but not in females. Thus, the BIA prediction equation needs to be developed and validated in the population under study.

Chinese Beiqishen tea was studied in an in vitro test system. ⋯ The tea infusion contained some non-desirable trace elements and caffeine in addition to polyphenols and tannins in high concentrations. Therefore, the consumption of this tea may involve risks.

To evaluate the stability of emulsions under different temperatures simulating clinical conditions of storage and exposure during infusion, five total nutrient admixture formulas in this institution were analyzed: adult, patients with hepatic failure, infants, stressed patients, and patients with renal failure. ⋯ For the safety of total nutrient admixtures, special attention is required to keep the ambient temperature below 28 degrees C and completely exclude air from the container.
