Repercusión psicológica de la hospitalización del neonato grave y crítico en la madre acompañante

Introducción: la hospitalización es una crisis no normativa en la vida familiar; tanto por la condición de salud que la genera, la gravedad que se asocia al hecho de requerir ser hospitalizado(a), como por la alteración de la rutina habitual del niño(a).Objetivo: describir la repercusión psicológica de la hospitalización de neonatos graves y críticos en la madre acompañante en la Unidad de Cuidados Intensivos Neonatal (UCIN) del Hospital General Docente Abel Santamaría Cuadrado de Pinar del Río durante el mes de febrero y la primera quincena de marzo del año 2015.Métodos: se realizó un estudio observacional, descriptivo y transversal. El universo estuvo conformado por las 19 madres acompañantes que ingresaron a la UCIN, la muestra fue de 13 madres acompañantes seleccionadas por muestreo no probabilístico intencional.Resultados: se mostró la diversidad de las repuestas psicológicas observadas en la madre acompañante donde se apreció predominio del miedo, la depresión y la ansiedad (28,9%, 22,2% y 20% respectivamente). Con menor frecuencia se observó la inculpación y la aprobación de la enfermedad con un 2,2%. Se debe señalar la existencia de un 8,9% que mostraron evasión y negación ante el acontecimiento absteniéndose de asistir en forma frecuente al servicio de UCIN y en ocasiones de visitar a los infantes.Conclusiones: muchos acontecimientos se observaron paralelos a los procesos de vivencia hospitalaria y de la propia gravedad del neonato como la escolaridad secundaria terminada, el bajo peso al nacer y la prematuridad. Las madres necesitan atención psicológica calificada con seguimiento e inclusión del resto de la familia como partícipe también del evento  hospitalización

Handedness for Unimanual Grasping in 564 Great Apes: The Effect on Grip Morphology and a Comparison with Hand Use for a Bimanual Coordinated Task

A number of factors have been proposed to influence within and between species variation in handedness in non-human primates. In the initial study, we assessed the influence of grip morphology on hand use for simple reaching in a sample of 564 great apes including 49 orangutans Pongo pygmaeus, 66 gorillas Gorilla gorilla, 354 chimpanzees Pan troglodytes and 95 bonobos Pan paniscus. Overall, we found a significant right hand bias for reaching. We also found a significant effect of the grip morphology of hand use. Grasping with the thumb and index finger was more prevalent in the right compared to left hand in all four species. There was no significant sex effect on the patterns of handedness. In a subsample of apes, we also compared consistency in hand use for simple reaching with previously published data on a task that measures handedness for bimanual actions. We found that the ratio of subjects with consistent right compared to left hand use was more prevalent in bonobos, chimpanzees and gorillas but not orangutans. However, for all species, the proportion of subjects with inconsistent hand preferences between the tasks was relatively high suggesting some measures may be more sensitive in assessing handedness than others

Human Rights and the War on Terror: Complete 2005 - 2007 Topical Research Digest

“9/11 changed everything.” Not really. In fact, there has been far more continuity than change over the past six years in both international and domestic politics. Nonetheless, human rights often have been harmed—although not by terrorism but by “the war on terror.

Cognitive evolution has been explained at the proximate level by shifts in absolute and relative brain volume and at the ultimate level by differences in social and dietary complexity. However, no study has integrated the experimental and phylogenetic approach at the scale required to rigorously test these explanations. Instead, previous research has largely relied on various measures of brain size as proxies for cognitive abilities. We experimentally evaluated these major evolutionary explanations by quantitatively comparing the cognitive performance of 567 individuals representing 36 species on two problem-solving tasks measuring self-control. Phylogenetic analysis revealed that absolute brain volume best predicted performance across species and accounted for considerably more variance than brain volume controlling for body mass. This result corroborates recent advances in evolutionary neurobiology and illustrates the cognitive consequences of cortical reorganization through increases in brain volume. Within primates, dietary breadth but not social group size was a strong predictor of species differences in self-control. Our results implicate robust evolutionary relationships between dietary breadth, absolute brain volume, and self-control. These findings provide a significant first step toward quantifying the primate cognitive phenome and explaining the process of cognitive evolution.PostprintPeer reviewe

Constructive and Deconstructive Tool Modification by Chimpanzees (Pan troglodytes)

Nine chimpanzees (Pan troglodytes) were tested for their ability to assemble or disassemble the appropriate tool to obtain a food reward from two different apparatus. In its deconstructed form, the tool functioned as a probe for one apparatus. In its constructed form, the tool functioned as a hook, appropriate for a second apparatus. Each subject completed four test trials with each apparatus type. Tool types were randomized and counter-balanced between the two forms. Results demonstrated that adult and juvenile chimpanzees (N = 7) were successful with both tool types, while two infant chimpanzees performed near chance. Off-line video analyses revealed that tool modifications followed by attempted solutions by the adults and juveniles were typically correct on the first attempt. Neither infant was successful in modifying tools correctly on the first attempt over all eight trials. The older chimpanzees’ ability to modify the appropriate tool consistently prior to use indicates an immediate recognition of the functional attributes necessary for the successful use of tool types on each apparatus, and represents a non-replication of a previously reported study by Povinelli
