Bibliography profiling of undergraduate theses in a professional psychology program

The bibliographic profile of 125 undergraduate (licentiate) theses was analyzed, describing absolute quantities of several bibliometric variables, as well as within-document indexes and average lags of the references. The results show a consistent pattern across the years in the 6 cohorts included in the sample (2001-2007), with variations, which fall within the robust confi dence intervals for the global central tendency. The median number of references per document was 52 (99% CI 47-55); the median  percentage of journal articles cited was 55%, with a median age for journal references of 9 years. Other highlights of the bibliographic profile were the use of foreign language references (median 61%), and low reliance on open web documents (median 2%). A cluster analysis of the bibliometric indexes resulted  in a typology of 2 main profiles, almost evenly distributed, one of them with the makeup of a natural science bibliographic profile and the second within the style of the humanities. In general, the number of references, proportion of papers, and age of the references are close to PhD dissertations and Master theses, setting a rather high standard for undergraduate theses.

Tissue- specific DNA methylation profiles in newborns

Experimental and epidemiological studies demonstrate that fetal growth restriction and low birth weight enhance the risk of chronic diseases in adulthood. Derangements in tissue-specific epigenetic programming of fetal and placental tissues are a suggested mechanism of which DNA methylation is best understood. DNA methylation profiles in human tissue are mostly performed in DNA from white blood cells. The objective of this study was to assess DNA methylation profiles of IGF2 DMR and H19 in DNA derived from four tissues of the newborn. We obtained from 6 newborns DNA from fetal placental tissue (n = 5), umbilical cord CD34+ hematopoietic stem cells (HSC) and CD34- mononuclear cells (MNC) (n = 6), and umbilical cord Wharton jelly (n = 5). HCS were isolated using magnetic-activated cell separation. DNA methylation of the imprinted fetal growth genes IGF2 DMR and H19 was measured in all tissues using quantitative mass spectrometry. ANOVA testing showed tissue-specific differences in DNA methylation of IGF2 DMR (p value 0.002) and H19 (p value 0.001) mainly due to a higher methylation of IGF2 DMR in Wharton jelly (mean 0.65, sd 0.14) and a lower methylation of H19 in placental tissue (mean 0.25, sd 0.02) compared to other tissues. This study demonstrates the feasibility of the assessment of differential tissue specific DNA methylation. Although the results have to be confirmed in larger sample sizes, our approach gives opportunities to investigate epigenetic profiles as underlying mechanism of associations between pregnancy exposures and outcome, and disease risks in later life.

Postgraduate Education for Physical Therapists at Cardiopulmonary Area in Colombia

This paper presents the supply of postdegree programs in the cardiopulmonary area in Colombia in orden to show its state and sufficiency. Plans of formation, objectives, curricular approach, methodology and profile of performance are analyzed in terms of costs, duration, supply, location and research capabilities. Our results show problems in regard to supply as well as unanimous criteria and strategic alliances. There are no Gremial associations that favor both discussion and analysis about epidemiologist aspects of respiratory and cardiovascular diseases in Colombia there is necessity of professionals in this area with experience. Knowledge and appropiated skills in management, administration, laws, agreements and public policies that cover the affected population. Also, it is exposed that the Universities whit this programs require support and pursuit for professionals positioning both in national and international context.Methodology A descriptive study was carried out with a data collection made in a period between April-December of 2006. Cards were done and they allowed to review different aspects such as costs, occupational profile, duration, modality, methodology, practical component and evaluation in the offering universities of programs of postdegree in the cardiopulmonary area for physiotherapists. Later an analysis was made on curriculum, profiles, objectives, contents, professional competitions the areas of research.

Reflections about physiotherapist professional performance in the field of physical activity

The physiotherapist professional activities, in the beginning were focused only in the clinical field, nowadays it has many different action fields including Physical Activity. Physical activity can be viewed from two dimensions: one biological, which is defined as any activity which requires energy expenditure involving the combined action of multiple systems; on the other side social, understood as a human activity concerning subjectivity conditions influenced by the environment where the individual and the community are developed. Given these dimensions as well as national and international benchmarks this paper’s objective is to present a series of reflections that the authors have done regarding the physiotherapist professional performance in the field of physical activity and the large possibilities derived from their practice in this field.
