Resumo.Introdução: Esta comunicação pretende descrever um estudo longitudinal acerca da aplicação da Escala do Desenho da Gravidez e da Escala da Sensibilidade Sonora-Musical na Gravidez, ambas construídas e validadas para este estudo, numa amostra de 211 mulheres grávidas aguardando a realização das ecografias do II e do III trimestres de gestação. Objectivos: 1) avaliar a evolução das variáveis do desenho da gravidez e das variáveis sonoro-musicais na passagem do II para o III trimestre e 2) analisar a contribuição de cada uma de estas variáveis para o estudo da psicologia da gravidez. Método: 1) estudo longitudinal comparando as variáveis do desenho da gravidez e a sensibilidade sonoro-musical observadas nos dois momentos de avaliação; 2) estudo correlacional entre cada uma destas variáveis e as variáveis de vinculação materna pré-natal e de orientação materna pré-natal. Instrumentos: Escala do Desenho da Gravidez (Carvalho, 2011), Escala da Sensibilidade Sonora-Musical na Gravidez (Carvalho & Justo, 2013), Escala de Vinculação Materna Pré-natal (versão Portuguesa, Camarneiro & Justo, 2010) e Questionário do Paradigma Placentário (versão portuguesa, Carvalho, 2011). Resultados: Os resultados revelam a existência de diferenças significativas, entre o II e o III trimestres nas variáveis estudadas, apontando para: a) um aumento da sensibilidade sonoro-musical no terceiro trimestre, b) uma evolução da auto-representação da imagem materna no terceiro trimestre e c) um aumento da frequência de representação gráfica da posição de apresentação fetal cefálica da imagem do bebé na passagem para o terceiro trimestre. Observaram-se correlações significativas entre, por um lado, as variáveis da sensibilidade sonoro-musical e as variáveis do desenho da gravidez e, por outro lado, as variáveis de orientação materna pré-natal. Registaram-se correlações significativas entre sensibilidade sonoro-musical, por um lado, e vinculação materna pré-natal e a orientação maternal pré-natal, por outro. Conclusão: Será importante investigar a dialética entre a representação do bebé imaginado através de medidas projectivas maternas e a percepção do comportamento fetal recorrendo à observação ecográfica e a medidas biofísicas e hemodinâmicas.Palavras chave: Gravidez, Escala do Desenho da Gravidez, Escala das Representações Sonoro-Musicais na Gravidez, Escala de Vinculação Materna Pré-Natal, Questionário do Paradigma Placentário.Abstract.Background: This paper aims to describe a longitudinal study about the use of the Drawing Pregnancy Scale and of the Sound-Music Representations in Pregnancy Scale, both of it created and validated in a sample of 211 pregnant women while waiting for sonograms of the II and III trimesters of pregnancy. Aims: 1) to assess, the evolution of variables in drawings of pregnancy and also of sound-music variables, by the transition of the II to the III trimester of gestation and 2) to analyze the contribution of each one of these variables for the psychological study of pregnancy. Method: 1) longitudinal study comparing variables in drawings of pregnancy and sound-music variables at the two moments of assessment; 2) correlational study between each one of these variables and variables of maternal pre-natal attachment and also of maternal pre-natal orientation. Instruments: Drawing Pregnancy Scale (Carvalho, 2011), Sound-Music Representations in Pregnancy Scale (Carvalho & Justo, 2013), Maternal Pre-natal Attachment Scale (Portuguese version, Camarneiro & Justo, 2010) and Placental Paradigm Questionnaire (Portuguese version, Carvalho, 2011). Results: Results show the existence of significant diferences between the II and the III trimestres in some of the variables under analysis, suggesting: a) a increase of the sound-music sensibility by the third trimester, b) an evolution of the maternal image at the third trimester and c) an increase of the frequency of the graphical representation of the cephalic fetal presentation of the baby’s image at the third trimester. Significant correlations were observed between, on one side, the variables of soundmusic sensibility and the variables of the pregnancy drawings and, on another side, variables of prenatal maternal orientation. Significant correlations between sound-music sensibility, on one side, and prenatal maternal attachment and prenatal maternal orientation, on the other side, were found. Conclusion: It will be important to investigate about the representation of the imagined baby through maternal projective measures and the perception of fetal behaviour using sonograms as well as biophysical and hemodynamic measures.Keywords: Pregnancy, Drawing Pregnancy Scale, Sound-Music Representations in Pregnancy Scale, Maternal Pre-natal Attachment Scale, Placental Paradigm Questionnaire.

1. Platelet angiotensin II binding, circulating angiotensin II levels, plasma renin substrate and plasma renin concentration were measured in a longitudinal study of 30 women during pregnancy and the puerperium. 2. There was a significant fall in platelet angiotensin II binding from 11 weeks gestation to 18 weeks gestation (P < 0.01). There were no further significant changes in platelet angiotensin II binding until after delivery, a significant rise in platelet angiotensin II binding being found at 6 weeks post partum as compared with at 36 weeks gestation (P < 0.01). There was no further significant change from 6 to 12 weeks post partum, and platelet angiotensin II binding at 6 and 12 weeks post partum in the pregnant cohort approximated to that in non-pregnant women. These changes parallel those known to occur in pressor responsiveness to angiotensin II in pregnancy. 3. Plasma angiotensin II concentration, plasma renin substrate and plasma renin concentration were all significantly higher during pregnancy than in the puerperium (P < 0.001). There were no significant changes during pregnancy in plasma angiotensin II concentration or plasma renin concentration, although plasma renin substrate rose throughout. 4. Significant inverse correlations between platelet angiotensin II binding and plasma angiotensin II concentration (P < 0.01), plasma renin substrate (P < 0.01) and plasma renin concentration (P 0>001) were found during pregnancy. These data suggest that down-regulation of platelet angiotensin II binding by the components of the renin-angiotensin system pertains in pregnancy. 5. We are currently investigating parallelism between platelet and vascular angiotensin-binding sites. If such is confirmed, studies of platelet angiotensin II binding in pregnancy may be of both basic physiological and clinical interest in relation to the hypertensive diseases of pregnancy.

Abstract We undertook a prospective longitudinal study of thyroid function in 36 pregnant women. There were significant increases in thyroxin-binding globulin, thyrotropin, and triiodothyronine. Albumin, free thyroxin (measured by an analog and a nonanalog method), and the free thyroxin index were significantly decreased. Results for the free thyroxin methods were correlated with each other in each trimester. We could find no evidence for artifacts related to albumin or thyroxin-binding globulin with either method for free thyroxin.
