Comparing Bedside Methods of Determining Placement of Gastric Tubes in Children
Purpose
The purpose of this study was to compare the accuracy and predictive validity of pH, bilirubin, and CO2 in identifying gastric tube placement errors in children.
Design and Methods
After the tube was inserted into 276 children, the CO2 monitor reading was obtained. Fluid was then aspirated to test pH and bilirubin.
Results
Lack of ability to obtain tube aspirate was the best predictor of NG/OG placement errors with a sensitivity of 34.9% and a positive predictive value of 66.7%. Measuring pH, bilirubin, and CO2 of tube aspirate was less helpful.
Practice Implications
Health care providers should suspect NG/OG tube misplacement when no fluid is aspirated

The bii4africa dataset of faunal and floral population intactness estimates across Africaâs major land uses
Sub-Saharan Africa is under-represented in global biodiversity datasets, particularly regarding the impact of land use on speciesâ population abundances. Drawing on recent advances in expert elicitation to ensure data consistency, 200 experts were convened using a modified-Delphi process to estimate âintactness scoresâ: the remaining proportion of an âintactâ reference population of a species group in a particular land use, on a scale from 0 (no remaining individuals) to 1 (same abundance as the reference) and, in rare cases, to 2 (populations that thrive in human-modified landscapes). The resulting bii4africa dataset contains intactness scores representing terrestrial vertebrates (tetrapods: ±5,400 amphibians, reptiles, birds, mammals) and vascular plants (±45,000 forbs, graminoids, trees, shrubs) in sub-Saharan Africa across the regionâs major land uses (urban, cropland, rangeland, plantation, protected, etc.) and intensities (e.g., large-scale vs smallholder cropland). This dataset was co-produced as part of the Biodiversity Intactness Index for Africa Project. Additional uses include assessing ecosystem condition; rectifying geographic/ taxonomic biases in global biodiversity indicators and maps; and informing the Red List of Ecosystems
Assumption without representation: the unacknowledged abstraction from communities and social goods
We have not clearly acknowledged the abstraction from unpriceable âsocial goodsâ (derived from
communities) which, different from private and public goods, simply disappear if it is attempted to
market them. Separability from markets and economics has not been argued, much less established.
Acknowledging communities would reinforce rather than undermine them, and thus facilitate
the production of social goods. But it would also help economics by facilitating our understanding
of â and response to â financial crises as well as environmental destruction and many social problems,
and by reducing the alienation from economics often felt by students and the public
