Questionnaires to evaluate pelvic floor dysfunction in the postpartum period: a systematic review.

Abstract: Background Pelvic floor dysfunctions (PFDs) affect the female population, and the postpartum period can be related to the onset or aggravation of the disease. Early identification of the symptoms and the impact on quality of life can be achieved through assessment instruments. Objective The purpose of this systematic review is to evaluate questionnaires used to assess PFD in the postpartum period. Methods A systematic review study was conducted, following Preferred Reporting Items for the Systematic Reviews and Meta-Analyses (PRISMA) criteria, using the databases: PubMed, Biblioteca Virtual de Saude (BVS), Web of Science, and Scopus, and the keywords PFD or pelvic floor disorders, postpartum or puerperium, and questionnaire. Articles published up till May 2018 were included, searching for articles using validated questionnaires for the evaluation of PFDs in postpartum women. The articles included were evaluated according to a checklist, and the validation studies and translated versions of the questionnaires were identified. Results The search of the databases resulted in 359 papers, and 33 were selected to compose this systematic review, using nine validated questionnaires to assess PFDs in the postpartum period: International Consultation on Incontinence Questionnaire - Vaginal Symptoms (ICIQ-VS), Pelvic Floor Distress Inventory 20 (PFDI-20), Pelvic Floor Impact Questionnaire (PFIQ-7), PFDI-46, Pelvic Floor Impact Questionnaire (PFIQ-31), Pelvic Floor Bother Questionnaire (PFBQ), Female Pelvic Floor Questionnaire, electronic Personal Assessment Questionnaire - Pelvic Floor, and PFD questionnaire specific for pregnancy and postpartum. The most frequently reported questionnaires included PFDI-20, PFIQ-7, and ICIQ-VS and are recommended by ICI. In addition, the review identified a specific questionnaire, recently developed, to access PFD during pregnancy and postpartum. Conclusion The questionnaires used to evaluate PFD during postpartum period are developed for general population or urology/gynecology patients with incontinence and reinforce the paucity of highly recommended questionnaires designed for postpartum, in order to improve early and specific approach for this period of life.

Investigating the affordances of a CAD enabled learning environment for promoting integrated STEM learning

Abstract: There has been an increased emphasis on designing integrated STEM learning environments for K-12 students that facilitate seamless learning of disciplinary concepts infused with science inquiry, engineering design, mathematical reasoning, and technological skills. However, there is limited prior research investigating how to facilitate such integrated STEM learning in formal classrooms that go beyond a simple combination of the different subject areas and instead enable teaching and learning of disciplinary concepts infused with scientific inquiry, engineering design, mathematical reasoning, and 21st century technological skills. In this paper, we investigate the affordances of using an educational Computer Aided Design tool, Energy 3D, and corresponding curricular materials to support such integrated STEM learning anchored in the engineering design process. We present an exploratory case study that was conducted in a middle school in the US, where a project-based learning approach was followed and students were asked to design a low-cost energy-efficient home within a given budget using the Energy3D CAD tool. Findings indicate that students learned to engage in the design process and demonstrated practices of idea fluency and systematic experimentation; practices usually representative of informed designers. During the design process while analyzing the problem space, generating ideas, and evaluating solutions, they developed better understanding of the relationships between variables and underlying science concepts, used various mathematical analysis tools and graphical representations embedded in the available technology to inform their engineering design decisions. The learning environment using Energy3D afforded formative feedback to help students understand relationship between variables, provided converging evidences using multiple analytical tools, and enabled visual problem decomposition using suboptimal model to engage students in integrated STEM learning. This study provides a platform for future research investigating the effectiveness of educational CAD tools and curricular scaffolds designed specifically for K-12 students for supporting integrated STEM learning anchored in the design process.

Communal Coping and Posttraumatic Growth in a Context of Natural Disasters in Spain, Chile, and Colombia:

Abstract: The aim of this study was to identify communal coping strategies that enhance posttraumatic growth of individuals, communities, and societies in the context of natural disasters. Participants were 540 people affected by floods in Colombia and by earthquakes in Spain and Chile. Posttraumatic growth was assessed at individual, community, and society levels. Direct and indirect relationships between trauma intensity and posttraumatic growth were analyzed to identify and evaluate the mediating role played by communal coping strategies. Growth and communal coping were reported in all nations, but means for posttraumatic growth at all three levels and communal coping were higher in the relatively more collectivistic countries, Colombia and Chile, than in the relatively more individualistic Spain. Spiritual coping was more frequent in the two Latin American nations, but it also predicted growth even in more secularized Spain. Social support was similar in Spain and Chile, and higher in Colombia, and played a mor...

Modelo teórico de aprendizaje organizacional

Abstract: Este articulo desarrolla una propuesta de modelo teorico del aprendizaje organizacional. Forma parte de un trabajo dentro de la linea de investigacion del conocimiento, y especificamente, del proyecto de investigacion en aprendizaje organizacional. Esta propuesta de modelo intenta predecir la incidencia de las variables independientes: fuentes de aprendizaje organizacional, sujetos del aprendizaje organizacional, cultura para el aprendizaje organizacional y condiciones para el aprendizaje organizacional. Por lo tanto fue necesario determinar como el aprendizaje organizacional es una variable de la perdurabilidad de las organizaciones a traves de ventajas competitivas; lo contrario acontecera para aquellas organizaciones que todavia arrastran caracteristicas estructurales anejas. Para ubicar las implicaciones administrativas del aprendizaje organizacional fue preciso caracterizar brevemente el contexto con el que se inicia este.

Sediment Transport and Geomorphological Change in a High-Discharge Tropical Delta (Magdalena River, Colombia): Insights from a Period of Intense Change and Human Intervention (1990–2010)

Abstract: Restrepo, J.C.; Schrottke, K.; Traini, C.; Ortiz, J.C.; Orejarena, A.; Otero, L.; Higgins, A., and Marriaga, L., 2016. Sediment transport and geomorphological change in a high-discharge tropical delta (Magdalena River, Colombia): Insights from a period of intense change and human intervention (1990–2010). There is strong indication that environmental changes and human interventions have affected freshwater discharge and sediment flux in the Magdalena River (northwestern South America) within the period from 1990 to 2010. Thus, stream flow, suspended sediment load (SSL), and riverbed dynamics were analysed in this study for estimating changes in the suspended sediment transport regime as well as of erosional/depositional patterns in different zones of the delta. It can be shown that stream flow increased at a higher rate than suspended sediment transport, promoting changes in the sediment transport regime. Erosion appeared at the mouth/frontal bar and the outlet zones and modified the sedimentary ...
