Repercussão das Colheitas de Sangue sobre os Valores de Hemoglobina em Recém-Nascidos de Muito Baixo Peso (RNMBP) Submetidos a Terapia Intensiva

A perda iatrogénica de sangue constitui um problema comum nas unidades de cuidados intensivos neonatais. O objectivo deste trabalho foi quantificaras espoliações de sangue para estudos analíticos em 22 RNMBP durante as primeiras três semanas de hospitalização. O número médio de colheitas por criança e por dia foi IA e o número médio de colheitas por criança no período estudado foi 29.7. O valor cumulativo médio de sangue espoliado pelo 21." dia foi 18,7 ml/kg. Os valores médios de hemoglobina nas primeiras 12 horas de tida e no 21." dia foram respectivamente 16.4 e 12.9 gr/d1. Verificou-se uma relação estreita entre o volume de sangue extraído e o volume de sangue transfundido. sugerindo este facto que. em geral. as transfusões são efectuadas por necessidade de compensar as perdas sanguíneas relacionadas com as colheitas de sangue. Conclui-se que as espoliações repetidas de sangue para análises laboratoriais se repercutem significativamente nos valores de hemoglobina dos recém-nascidos pretermo e de MBP sendo portanto desejável que tais espoliações sejam rigorosamente quantificadas e reduzidas ao mínimo tendo em conta os riscos das transfusões de sangue

Tratamientos de consolidación aplicados en materiales cerámicos: ¿Son homogéneos?

The mass consolidation treatment of azulejos is necessary when ceramic biscuits show signs of disaggregation. Such treatment is often used as a complementary conservation technique to the reestablishment of weakened glaze-ceramic bonds. In this research, two commonly used consolidants (ethyl silicate and acrylic resin) were tested on artisanal ceramic tiles via mass consolidation and the resulting impregnation profiles were evaluated. The results indicated that after consolidation, hard zones frequently formed due to localized consolidant concentration after the polymerization and curing processes. These inhomogeneous hard zones subsequently influenced the results obtained through conventional mechanical strength testing (i.e. flexural and compression), creating a false impression of success. This research demonstrated that by using the Drilling Resistance Measuring System, impregnation characteristics such as penetration depth and distribution of consolidant could be observed that otherwise could not be discerned through the more common testing methods. As such, a more extensive evaluation of consolidation effects was achieved.En la conservación de los azulejos alterados se utilizan productos con acción consolidante a fin de recuperar la cohesión del cuerpo cerámico disgregado. En este trabajo se investiga el efecto de la consolidación de dos productos muy utilizados en la práctica de la conservación de los azulejos (un silicato de etilo comercial y una resina acrílica), aplicados en un material cerámico artesanal. Los resultados obtenidos indican que pueden producirse zonas con resistencias mayores debido a la concentración local del producto y, a la vez de un material consolidado homogéneo, resulta un material heterogéneo. Por otro lado, la existencia de estas zonas puede conducir a falsos resultados en los ensayos destructivos (resistencia mecánica a la flexión y compresión) utilizados frecuentemente en la evaluación de la acción de consolidación. Se demuestra que mediante el uso de la resistencia a la perforación (DRMS) es posible definir las características, la distribución y el patrón de impregnación, los cuales no pueden ser observadas por los métodos comúnmente utilizados

Use of granulocyte growth factors: recommendations of the Portuguese Society of Hematology

The administration of cytotoxic chemotherapy may be complicated by the emergence of neutropenia and febrile neutropenia, frequently determining hospital admission and intravenous treatment with broad spectrum antibiotics. Frequently, it is necessary to reduce the dose or to delay the administration of the cytotoxic drugs reducing the relative dose intensity of the chemotherapy regimen. Granulocyte growth factors stimulate the proliferation and differentiation of neutrophils and reduce the number of days of severe neutropenia and febrile neutropenia associated with cytotoxic chemotherapy. They are also indicated for the collection of hematopoietic progenitors for autologous and allogeneic transplantation, as well as in non malignant diseases associated with chronic neutropenia. This article reviews the evidence supporting the use of granulocyte growth factors in Hematology

An analysis of innovation in textile companies: an efficiency approach

[EN] The elimination of trade contingency measures in 2005 triggered a process of renewal in the textile sector, requiring major investments. The divide between efficiency and innovation has become an issue of major importance for decision-making in the Spanish textile sector. This study provides quantitative data on the efficiency levels of innovative Spanish textile companies. The aim is to identify their distinguishing features and establish a possible pattern to follow. In addition, truncated regression is used to estimate the determinants of efficiency, in order to check the significance of innovation processes for firms.Puertas Medina, RM.; Martí Selva, ML.; Calafat Marzal, MC.

ISC'2 experimental site - prediction & performance of instrumented axially loaded piles

This paper is part of a joint research project to study the behaviour of piles in residual soil. An experimental test site on residual (saprolitic) soil from granite was constructed at the Faculty of Engineering of the University of Porto. A very extensive site characterization has been held, including a large variety of in situ tests in order to develop an International Prediction Event (Class A) of Bored, CFA and Driven Piles. Researchers and designers were invited to deal with this investigation results in order to predict the real response of the pile foundations. Several in-situ testing techniques were used - Penetration tests: SPT and CPTU; Pressure-dilatometer tests: PMT and DMT; Seismic: Cross-Hole (CH) and Down-Hole (DH). Undisturbed samples were recovered and an extensive laboratory-testing program was carried out, including oedometric consolidation tests, CKOD triaxial tests using local strain measuring devices and bender-extender elements, as well as resonant column tests. This paper focuses on the axial pile load tests and a analysis of the predictions is presented
