Net protein utilization during total parenteral nutrition of injured critically ill patients: an original approach
No full textTraumatized critically ill patients with either a moderate or severe catabolic response were studied. Patients were randomly allocated to receive an intravenous solution which was either protein-free or contained protein and hypertonic glucose. The overall energy intake in both groups was equivalent to each patient's daily requirement. In both the moderately catabolic and severely catabolic patients the urinary nitrogen loss with the protein-free solution was negatively correlated to the energy intake/energy need ratio (p less than 0.01, moderate catabolism; p less than 0.001, severe catabolism). The ratio of energy intake/energy need was correlated with the nitrogen loss. From the resultant straight line, the obligatory nitrogen loss was determined for those patients receiving the protein containing solution (test diet). The net protein utilization was subsequently calculated using this value of the obligatory nitrogen loss. The net protein utilization was inversely correlated with the severity of trauma. It was significantly (p less than 0.005) greater in the patients with a moderate catabolic response. In the acute postinjury phase, the net protein utilization of infused amino acids was similar to that for protein fed orally to normal healthy subjects

Combined use of mask CPAP and minitracheotomy as an alternative to endotracheal intubation. Preliminary observation
No full textWe describe the combined use of mask CPAP (continuous positive airway pressure) and minitracheotomy as an alternative to conventional endotracheal intubation in 3 patients requiring CPAP, secretion removal and diagnostic procedures such as bronchoalveolar lavage and bronchial cultures. These requirements were fulfilled with the combined technique approach, thus preserving glottic function and avoiding the disadvantages of endotracheal intubation of tracheotomy. This approach seems particularly suitable in the treatment of immunocompromised patients because of its reduced invasiveness
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
