Abstract Controlled-flow ion chromatography has significantly improved the precision with which inorganic sulfate (SO4) can be measured in serum. In this study, we have shown that serum SO4 is increased in pregnancy. The increase appears to follow gestational age, resulting in a 39% higher value by the middle of the third trimester. We suggest that this increase is a natural physiological process, which enhances SO4 availability to the growing fetus and placenta.

Abstract Background Many efforts have been focused on the alternative glycemic marker glycated albumin (GlyA) and its application in pregnancy during which profound physiological changes take place. Our objective was to determine the reference intervals (RIs) of GlyA in healthy Chinese pregnant women and to assess the predictive value of serum GlyA in adverse pregnancy outcomes. Methods Totally 421 healthy subjects including 137 in the first trimester, 152 in the second trimester, and 132 in the third trimester were enrolled from March to July 2019, for the purpose of establishing the trimester-specific RIs of GlyA. In addition, 67 pregnant women diagnosed with GDM were enrolled at 24–28 weeks of gestation. The diagnostic value of GlyA for GDM patients was evaluated and compared with that of fasting plasma glucose (FPG) at 24–28 weeks of gestation. The association between GlyA in the late pregnancy and the adverse pregnancy outcomes was analyzed with the data collected from January to June 2018 at our hospital. Results The estimated RIs of GlyA in present study were 11.26–15.10%, 10.04–13.50%, and 9.76–13.09% in the first, second, and third trimesters respectively. The areas under receiver operating characteristic (ROC) curves were 0.503 for GlyA and 0.705 for FPG. More importantly, the GlyA level in the third trimester was not more elevated in the patients with adverse pregnancy outcomes including large for gestational age (LGA), preterm delivery, hypertension and preeclampsia (PE). The exception was made with the GDM patients who suffered from postpartum hemorrhage and had significantly higher GlyA levels than the control group. Conclusions Our results showed that the GlyA was continuously decreased as the gestational age went up. The GlyA testing has limited value in diagnosing GDM and predicting adverse pregnancy outcomes.

Objectives: to compare the accuracy of equations F.P. Hadlock and computer programs by V.N. Demidov in determining gestational age and fetal weight in the third trimester of gestation. Materials: 328 patients in terms 36–42 weeks of gestation are examined. Ultrasonography was performed in 0–5 days prior to childbirth. Results: it is established that the average mistake in determination of term of pregnancy when using the equation of F.P. Hadlock made 12,5 days, the computer program of V.N. Demidov – 4,4 days (distinction 2,8 times). The mistake within 4 days, when using the equation of F.P. Hadlock has met on average in 23,1 % of observations, the computer program of V.N. Demidov — 65,9 % (difference in 2,9 times). The mistake more than 10 days, took place respectively in 51,7 and 8,2 % (distinction by 6,3 times). At a comparative assessment of size of a mistake in determination of fetal mass it is established that when using the equation of F.P. Hadlock it has averaged 281,0 g, at application of the computer program of V.N. Demidov — 182,5 g (distinction of 54 %). The small mistake in the mass of a fetus which isn't exceeding 200 g at application of the equation of F.P. Hadlock has met in 48,1 % of cases and the computer program of V.N. Demidov — 64,0 % (distinction of 33,1 %). The mistake exceeding 500 g has been stated in 18 % (F.P. Hadlock) and 4,3 % (V.N. Demidov) respectively (distinction 4,2 times). Conclusions: the computer program of V.N. Demidov has high precision in determination of term of a gestation and mass of a fetus in the III pregnancy.

Abstract Objectives An elevated sFlt-1/PlGF-ratio has been validated as a significant predictor of preeclampsia, but has not been established in women with rheumatoid arthritis (RA). We explored whether the sFlt-1/PlGF-ratio could be altered due to disease activity in RA, and could be applied in this population to predict preeclampsia. Since sulfasalazine has been suggested to improve the angiogenic imbalance in preeclampsia, we also aimed to examine whether sulfasalazine could affect sFlt-1 or PlGF levels. Methods Making use of a nationwide, observational, prospective cohort study on pregnant women with RA, sFlt-1 and PlGF were measured in the third trimester. A total of 221 women, aged 21–42 years, were included, with a median gestational age of 30 + 3 weeks. Results No differences in sFlt-1 or PlGF were observed between women with high, intermediate or low disease activity (p= 0.07 and p= 0.41), whereas sFlt-1 and PlGF did not correlate with DAS28-CRP score (r=-0.01 and r=-0.05, respectively). Four (2%) women with a sFlt-1/PlGF-ratio ≤38 developed preeclampsia in comparison to three (43%) women with a ratio > 38, corresponding to a negative predictive value of 98.1%. Sulfasalazine users (n = 57) did not show altered levels of sFlt-1 or PlGF in comparison to non-sulfasalazine users (n = 164, p= 0.91 and p= 0.11). Conclusion Our study shows that in pregnant women with RA, the sFlt-1/PlGF-ratio is not altered due to disease activity and a cut-off ≤38 can be used to exclude preeclampsia. Additionally, sulfasalazine use did not affect sFlt-1 or PlGF levels in this population.

Ibuprofen-related renal tubular acidosis (RTA) has not been previously described in pregnancy but its occurrence outside of pregnancy is being increasingly described. In this case, a 34-year-old woman presented in the third trimester of pregnancy with Type 1 or distal RTA related to ibuprofen and codeine abuse. It was complicated by acute on chronic renal dysfunction and hypokalemia. Delivery at 37 weeks gestation due to concerns of evolving preeclampsia resulted in the birth of a healthy neonate. RTA and hypokalemia were remediated and ibuprofen and codeine abuse ceased. Some renal dysfunction however continued. Thorough and repeated history taking as well as vigilance for this condition is suggested.

Abstract. Plasma renin concentration (PRC), plasma aldosterone concentration (PAC), and blood pressure were determined in the third trimester in pregnancy, 5 days and 6 months after delivery in pre-eclampsia, essential and transient hypertension in pregnancy and in normotensive pregnant and non-pregnant control subjects. PRC and PAC were elevated several fold above non-pregnant level in all groups during pregnancy. In pre-eclampsia PRC and PAC were 220 and 160%, respectively, above the levels 6 months after delivery, and thus lower than the corresponding values, 360 and 402%, in normotensive pregnancy. In essential and transient hypertension PRC and PAC increased to the same degree as during normotensive pregnancy. Urinary sodium excretion, serum sodium and creatinine clearance were reduced in pre-eclampsia, but not in essential and transient hypertension when compared to normotensive pregnant controls. All the parameters determined were the same as in non-pregnant controls 6 months after delivery in all groups. There were no correlations between blood pressure and PRC or PAC in any of the groups neither in pregnancy nor after delivery. It is concluded that the renin-aldosterone system is stimulated in lesser degree in pre-eclampsia than in both essential hypertension, transient hypertension and normotensive pregnancy, and there was no evidence for a causal relationship between the renin-aldosterone system and blood pressure neither in normotensive nor hypertensive pregnancy.

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.
