Student engagement in Portuguese schools : A national project

The 31st International School Psychology Association (ISPA) Conference will be held in Malta from 7-11th July 2009. The conference theme is "School Psychology for Diversity".

Primary prevention of neural tube defects: data from the portuguese national registry of congenital anomalies (RENAC)

Background: In Portugal folic acid supplementation is recommended to start at least 2-3 months before conception for primary prevention of Neural Tube Defects. The aim of this study was to evaluate, within gestations with at least one congenital anomaly, possible association between maternal socio-demographic factors and the use of folic acid. Methods: Using data from the Portuguese national registry of congenital anomalies, for the 2004-2013 period, the association between folic acid use during pregnancy and maternal characteristics was studied using the chi-square test. Results: Considering all reported cases with congenital anomaly, the use of folic acid before conception was reported by 12.7% (n = 1233) of the women; 47.8% (n = 4623) started supplementation during the 1st trimester, 7% (n = 680) did not take folic acid and 32.5% (3143) of the records had no information on folic acid use. Women with professions that require higher academic differentiation started the use of supplements before pregnancy (p <0.001); women under 19 years old and with Arab ethnicity (p <0.001) did not take folic acid. Mothers with a previous pregnancy reported less use of folic acid (11.5% versus 14.7%) than mothers without a previous pregnancy (p <0.001). Conclusions: The results suggest some degree of association between maternal characteristics and use of folic acid. To increase the consumption of folic acid before pregnancy new measures are need to promote this primary prevention, among couples and health professionals. This study highlights some maternal characteristics and subgroups of mothers for who the measures should be reinforced.

USE OF STARTER CULTURES TO IMPROVE PORTUGUESE TRADITIONAL SAUSAGES

In Mediterranean countries, such as Portugal, traditional dry-fermented sausages are highly appreciated. They are often still being manufactured in small processing units, according to traditional procedures. The aims of the present study were to evaluate the effect of different starter cultures and their optimal concentration, to reduce the microbial load in end-products, with the purpose to improve the sausages’ safety, without deteriorating sensory acceptability. pH, aw, colour, texture and microbiological profile were assessed. On the other hand, a sensory panel evaluated the products. Based on the first results, S. xylosus and L. sakei were chosen to be inoculated together with a yeast strain. In the mixed starter culture experiment, a food safety issue arose probably related to the higher aw value (0.91). The presence of Salmonella spp. detected in a few end-products sausages did not allow a full sensory evaluation in the mixed starter culture experiment. However, in the two preliminary experiments, the use of starter cultures did not depreciate the panellists’ overall appreciation and products acceptability.

Absence of prenatal ultrasound surveillance: Data from the Portuguese congenital anomalies registry

In Portugal, prenatal care guidelines advocate two prenatal ultrasound scans for all pregnant women. Not following this recommendation is considered inadequate prenatal surveillance. The National Registry of Congenital Anomalies (RENAC in Portuguese) is an active population-based registry and an important instrument for the epidemiological surveillance of congenital anomalies (CA) in Portugal. Regarding pregnancies with CA, this study aims to describe the epidemiology of absent prenatal ultrasound scans and factors associated with this inadequate surveillance.
