Proa valdearinnoensis is a relatively large‐headed and stocky iguanodontian dinosaur from the latest Early Cretaceous of Spain. Its braincase is known from three specimens. Similar to that of other dinosaurs, it shows a mosaic ossification pattern in which most of the bones seem to have fused together indistinguishably while a few (frontoparietal, basioccipital) might have remained loosely attached. The endocasts of the three specimens are described based on CT data and digital reconstructions. They show unmistakable morphological similarities with the endocast of closely related taxa, such as Sirindhorna khoratensis (which is close in age but from Thailand). This supports a high conservatism of the endocranial cavity. The issue of volumetric correspondence between endocranial cavity and brain in dinosaurs is analyzed. Although a brain‐to‐endocranial cavity (BEC) index of 0.50 has been traditionally used, we employ instead 0.73. This is indeed the mid‐value between the situation in adults of Alligator mississippiensis and Gallus gallus, which are members of the extant bracketing taxa of dinosaurs (Crocodilia and Aves). We thence gauge the level of encephalization of P. valdearinnoensis through the calculation of the encephalization quotient (EQ), which remains valuable as a metric for assessing the degree of cognitive function in extinct taxa, especially those with fully ossified braincases like dinosaurs and other archosaurs. The EQ obtained for P. valdearinnoensis (3.611) suggests that this species was significantly more encephalized than most if not all extant nonavian, nonmammalian amniotes. Our work adds to the growing body of data concerning theoretical cognitive capabilities in dinosaurs and supports the idea that an increasing encephalization was fostered not only in theropods but also in parallel in the shorter‐lived lineage of ornithopods. P. valdearinnoensis was ill‐equipped to respond to theropod dinosaurs and possibly lived in groups as a strategy to mitigate the risk of being predated upon. We hypothesize that group‐living and protracted caring of juveniles in this and possibly many other iguanodontian ornithopods favored a degree of encephalization that was outstanding by reptile standards.
Because chronic pain patients "move" in and out of employment and for work capacity status after pain facility treatment, future outcome studies using these measures will have to consider carefully the impact of "movement" on their results.
Introduction: Disease related malnutrition (DRM) affects at least one in four inpatients, increasing both morbidity and mortality during admission and after discharge. Nevertheless, its repercussion on hospital activity is not properly quantified. Objective: To determine the impact of an adequate coding of DRM and procedures employed to reverse it in the hospital average weight and other hospital indicators. Methods: Comparative study carried out in every patients requiring nutritional support and followed up by the Clinical Nutrition and Dietetics Unit of the Endocrinology and Nutrition Department in Complejo Asistencial Universitario de León (Spain) in 2008 and 2013. A nutritional coding report at discharge including diagnosis, nutritional treatment and access was performed following ICD-9-MC.Average weight, average length of stay adjusted by case-mix and case-mix index were compared before and after coding. Results: Hospital average weight increased after coding, both in 2008 (+4.1%) and 2013 (+1.7%) and especially in those departments in which nutritional screening is performed (Hematology, +10.5%). Average length of stay adjusted by case-mix was reduced under 1 (-5.7% and -0.2% in 2008 y 2013), pointing out to better functioning, and functioning index also decreased (-5.6% y -0.4% in 2008 and 2013), what means a higher efficiency. Conclusion: Adequate coding of nutritional diagnosis and treatment of patients with DRM increases the average weight of our hospital and improves average length of stay adjusted by case-mix and functioning index.Impacto de una adecuada codificación de la desnutrición relacionada con la enfermedad en los índices hospitalarios Influence of an appropriate coding of disease-related malnutrition in clinical indexes
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
