RESUMO

BACKGROUND AND OBJECTIVES: Recommendations in pediatrics call for general developmental screening of young children; however, research suggests social-emotional development, in particular, is important as an initial indicator of general well-being versus risk. We aim to describe a program designed to identify the social-emotional status of young children in the pediatric setting by using the Ages and Stages Questionnaires: Social-Emotional (ASQ:SE) as a universal screening tool, and to assess the effect of interventions by a colocated psychologist on changes in ASQ:SE scores over time. METHODS: In a prospective cohort design we analyzed scores on ASQ:SE surveys completed on children 6 to 36 months of age, to determine if children were at risk for problems in social-emotional development. The probability of remaining at risk over time was then compared between subjects receiving intervention by the psychologist, and those who declined intervention. Logit specifications were used in multivariate comparisons to control for a set of covariates. RESULTS: Three thousand one hundred and sixty-nine children were screened; 711 (22.4%) scored at or above the risk cutoff. Among the 711 at-risk children, 170 were rescreened. At the time of rescreening, those children who received intervention from the psychologist showed significant improvement on ASQ:SE scores compared with those who declined intervention (P = .01). CONCLUSIONS: Universal social-emotional screening in a busy pediatric practice is challenging. Significant percentages of children can be identified as being at risk for social-emotional problems, and colocation of a psychologist promotes the ability to effectively address young children's social-emotional development within their medical home.

RESUMO

The objective of this study was to examine the validity of the Child Behavior Checklist (CBCL) Posttraumatic Stress Disorder (PTSD) subscale to screen for PTSD in children attending an inner-city early childhood mental health center. Using various measures, we assessed 51 preschool-age children with high exposure to trauma receiving outpatient child-parent psychotherapy for PTSD. We compared 15 items on the CBCL, a proposed subscale indicative of PTSD, to the UCLA-PTSD Index and to clinical diagnosis based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) and the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (rev. ed.; DC:0-3; Zero to Three, 2005). Using the DC:0-3 criteria, 24% of the children were diagnosed with PTSD, but only 4% using the DSM-IV. The CBCL-PTSD subscale did not reach significant sensitivity or specificity to be a valuable screening tool for PTSD in this population.

RESUMO

Protein palmitoyltransferases (PATs) represent an exciting new target for anticancer drug design due to their pivotal roles in the subcellular localization of a number of oncogenes. We show that the Huntingtin interacting protein 14 (HIP14) is a PAT with a preference for the farnesyl-dependent palmitoylation motif found in H- and N-RAS. Characterization of HIP14 in mouse cells has revealed that it has the ability to induce colony formation in cell culture, anchorage-independent growth, and tumors in mice. Activity of the enzyme and its ability to transform cells is dependent on critical residues in the active site of the enzyme.

RESUMO

We demonstrated previously that alpha8beta1 integrin regulates the migration and survival of immature neurons during development of the chicken optic tectum; however, the potential extracellular ligand was unknown. We used immunohistochemistry to determine if several potential ligands (fibronectin, tenascin, vitronectin, and osteopontin) were expressed during neuronal migration along radial glia (RG). Fibronectin was localized in a pattern relevant to radial migration and survival of neurons; it was present before and during neuronal migration and appeared oriented along RG fibers by conventional fluorescence microscopy. Confocal microscopy confirmed that fibronectin was localized along RG cells during radial migration. It was more concentrated in some superficial laminae, which might support directional movement. Fibronectin was present after formation of definitive tectal laminae, but was diffuse and not aligned along RG, which persist. Flow cytometry analysis of dissociated optic tectum cells revealed that almost all RG were positive for fibronectin. Short-term cell culture experiments using an exocytosis inhibitor revealed that fibronectin accumulated in most RG cells. Thus, fibronectin is produced by RG and is aligned along their surfaces before and during migration. Fibronectin, therefore, is a potential ligand for general radial neuronal migration in the chick optic tectum. Its predominant source appears to be RG, in contrast with developing mammalian cortex, where fibronectin was not found in a pattern that could guide widespread radial migration and where neurons are the predominant producers of fibronectin during migration.
