Actividad física durante el embarazo y su relación con la ganancia de peso gestacional / Physical activity during pregnancy and its relationship with gestational weight gain / Atividade física durante a gestação e sua relação com o ganho de peso gestacional

Objetivo: describir los patrones de actividad física de una cohorte de gestantes de nuestro medio y explorar su asociación con la ganancia de peso en cada uno de los trimestres del embarazo. Método: estudio descriptivo longitudinal sobre una muestra de 151 mujeres. Se utilizó el Cuestionario Internacional de Actividad Física para evaluar la actividad física durante el embarazo en función del volumen, intensidad y ámbito de realización. Se llevaron a cabo diferentes modelos de regresión lineal múltiple para analizar la asociación entre actividad física y ganancia de peso gestacional. Resultados: la actividad física disminuyó durante el embarazo, tanto en tiempo como en intensidad. El índice de masa corporal pre-gestacional fue el principal factor asociado con una menor ganancia de peso a lo largo de todo el embarazo. La influencia de la actividad física sobre la ganancia de peso gestacional se limitó al tercer trimestre del embarazo en el que se observó una asociación inversa entre ambas variables. Conclusión: los resultados de este estudio muestran un importante descenso de la actividad física en la época del embarazo y sugieren una influencia limitada de ésta sobre la ganancia de peso gestacional.

Objective: to describe the physical activity patterns of a cohort comprised by pregnant women from our environment and to explore its association with weight gain in each of the trimesters of pregnancy. Methods: a descriptive and longitudinal study conducted with a sample of 151 women. The International Physical Activity Questionnaire was used to assess physical activity during pregnancy based on volume, intensity and setting where it is performed. Different multiple linear regression models were performed to analyze the association between physical activity and gestational weight gain Results: physical activity decreased during pregnancy, both in terms of time and intensity. Pre-gestational Body Mass Index was the main factor associated with lower weight gain throughout pregnancy. The influence of physical activity on gestational weight gain was limited to the third trimester of pregnancy, where an inverse association was observed between both variables. Conclusion: the results of this study show an important reduction in physical activity during pregnancy and suggest that it exerts a limited influence on gestational weight gain

O índice de massa corporal pré-gestacional foi o principal fator associado ao menor ganho de peso ao longo da gestação. A influência da atividade física no ganho de peso gestacional limitou-se ao terceiro trimestre de gestação, no qual foi observada associação inversa entre ambas as variáveis. Conclusão: os resultados deste estudo mostram uma diminuição significativa da atividade física no momento da gravidez e sugerem uma influência limitada desta no ganho de peso gestacional.

Capacidad del diámetro biparietal para predecir los recién nacidos grandes para edad gestacional. Estudio de cohorte retrospectivo / Ability of biparietal diameter to predict large for gestational age newborns. A retrospective cohort study

Fundamento: Predecir el recién nacido grande para la edad gestacional es una acción de salud que necesita de herramientas tecnológicas de probada eficiencia. Objetivo: Determinar la capacidad predictiva del diámetro biparietal en los recién nacidos grandes para la edad gestacional. Metodología: Estudio de cohorte retrospectivo que incluyó 1959 gestantes cubanas con embarazo simple con captación y término del embarazo entre enero del 2009 y diciembre de 2017. En cada trimestre de gestación se compararon las condiciones tróficas adecuado para la edad gestacional (AEG) y grandes para la edad gestacional (GEG) mediante estadígrafos de tendencia central (media) y de dispersión (rango, desviación estándar) correspondientes al diámetro biparietal. Se calculó además el intervalo de confianza (IC) de 95 % para la diferencia de medias del diámetro biparietal. Asimismo, se realizó un análisis de curvas ROC para determinar si el diámetro biparietal y el peso fetal predicen la condición trófica grande para la edad gestacional en el segundo y tercer trimestre de gestación. Los datos fueron recogidos del libro registro de genética del área de salud. Resultados: El diámetro biparietal en el segundo y tercer trimestre de gestación tuvo un área bajo curva de 0.60 (IC 95 %: 0.54-0.65) y 0.59 (IC 95 %: 0.54-0.64) respectivamente. Los puntos de corte establecidos (T2: 56.55 mm, T3: 81.55 mm) tienen una especificidad y exactitud superior al 78 %. Conclusiones: El diámetro biparietal y los modelos de regresión de Shepard y de Hadlock V mostraron capacidad para discriminar el nacimiento grande para la edad gestacional del adecuado para la edad gestacional, a partir del segundo trimestre de gestación siendo más eficaces en el tercero.

Background: Predicting large for gestational age newborns is a medical action that requires technological tools with proven efficiency. Objective: To determine the predictive ability of biparietal diameter in large newborns for gestational age. Methodology: Retrospective cohort study that included 1959 Cuban pregnant women with a singleton pregnancy, with recruitment and pregnancy term between January 2009 and December 2017. In each gestational trimester, trophic conditions appropriate for gestational age (GAW) were compared and large for gestational age (GA) using central tendency (mean) and dispersion (range, standard deviation) statistics corresponding to the biparietal diameter. The 95% confidence interval (CI) for mean biparietal diameter difference was also calculated. In addition, an analysis of ROC curves was performed to determine if biparietal diameter and fetal weight predict large trophic condition for gestational age in the second and third gestational trimester. Data were gathered from the health area genetics registry book. Results: Biparietal diameter in the second and third trimester of gestation had an area under curve of 0.60 (95% CI: 0.54-0.65) and 0.59 (95% CI: 0.54-0.64) respectively. The established cut-off points (T2: 56.55 mm, T3: 81.55 mm) have a specificity and accuracy greater than 78%. Conclusions: Biparietal diameter and the Shepard and Hadlock V regression models showed ability to discriminate large for gestational age birth from adequate for gestational age birth from the second trimester of gestation onward, being more effective in the third trimester.

The role of methylation of placental glucocorticoid response gene in the association between pregnancy-related anxiety in the third trimester and birth outcomes / 中华预防医学杂志

Objective: To investigate the role of methylation of placental glucocorticoid response gene in the association between pregnancy-related anxiety in the third trimester and birth outcomes. Methods: Based on a prospective cohort study, singleton live births and their mothers from the Ma'anshan Birth Cohort Study (MABC) were included as participants in this study. The maternal pregnancy-related anxiety symptoms in the third trimester of pregnancy were evaluated by using the Pregnancy-related Anxiety Questionnaire. The neonatal birth outcomes were collected from medical records. The placental tissues from 300 pregnant women with pregnancy-related anxiety and 300 without pregnancy-related anxiety were collected to detect the methylation of FKBP5, NR3C1 and HSD11B2 genes using the Methyl Target approach. The methylation factors were extracted by exploratory factor analysis. Linear regression or logistic regression models were used to analyze the association between pregnancy-related anxiety in the third trimester, methylation factor scores, and birth outcomes. The mediating role of methylation factors in the association between pregnancy-related anxiety in the third trimester and birth outcomes was analyzed by using the Process procedure. Results: The mean age of 2 833 pregnant women was (26.60±3.60) years old. After adjusting for confounding factors, pregnancy-related anxiety in the third trimester increased the risk of small-for-gestational-age (OR=1.32, 95%CI:1.00-1.74). A total of 5 methylation factors were extracted, and the factor 5 was loaded with FKBP5 CpGs 18-21. Pregnancy-related anxiety in the third trimester was negatively correlated with the factor 5 (β=-0.24,95%CI:-0.44--0.05). The factor 5 was positively correlated with the gestational age (β=0.17, 95%CI:0.06-0.27). In addition, the factor 2 (β=0.02,95%CI:0.00-0.04) and factor 3 (β=0.03,95%CI:0.01-0.05) were positively correlated with 5-min Apgar score after delivery. However, this study did not found the mediating role of the scores of the factor characterized by FKBP5 in the relationship between pregnancy-related anxiety and birth outcomes. Conclusion: Pregnancy-related anxiety in the third trimester may reduce the methylation level of FKBP5 CpGs 18-21 in placental tissues and is associated with the risk of small-for-gestational-age.

Efeitos do tratamento manipulativo osteopático na hemodinâmica e na qualidade de vida de gestantes no terceiro trimestre: coorte prospectiva / Effects of osteopathic manipulative treatment on the hemodynamics and quality of life of pregnant women in the third trimester: prospective cohort

Na gestação várias mudanças pelas quais as mulheres passam são capazes de intervir no seu estado de saúde. Estudos relatam que a incapacidade do corpo de algumas gestantes de acomodarem o crescimento uterino estaria na raiz de problemas na hemodinâmica materno-fetal. A busca por terapêuticas não medicamentosas vem crescendo dentro da área da saúde nos últimos anos. O tratamento manipulativo osteopático é uma terapêutica integrativa complementar de saúde reconhecida pela organização mundial de saúde e aceita pelo sistema único de saúde brasileiro. Método: Trata-se de uma coorte prospectiva realizada com 80 pacientes do ambulatório de pré-natal e da enfermaria de gestantes do Instituto Fernandes Figueira/Fiocruz entre julho de 2021 e setembro de 2022. Foram realizados dois estudos, um estudo transversal com 51 grávidas para avaliar os efeitos hemodinâmicos materno-fetais após o tratamento manipulativo osteopático através da dopplervelocimetria nas gestantes e um estudo prospectivo com 64 gestantes para avaliar a influência do tratamento manipulativo osteopático sobre a intensidade das dores lombar e pélvica, assim como mudanças na sua qualidade de vida. População: foram investigadas gestantes no terceiro trimestre de gestação, acima de 18 anos, e excluídas as gestantes com ruptura prematura de membrana, com malformações fetais, com fetos múltiplos e trabalho de parto ativo. Resultados: Os resultados do estudo transversal após o tratamento manipulativo não foram significantes estatisticamente. No estudo prospectivo, as gestantes foram divididas em dois grupos ≤ 3 e ≥ 4. Observou-se uma melhora significante estatisticamente na intensidade das dores lombar e pélvica em ambos os grupos. Houve melhora nos dois grupos nos índices de qualidade de vida, sendo que no grupo≥ 4 atendimentos todos os resultados foram estatisticamente significativos. Conclusão: a análise dos dados do estudo considerou que o tratamento manipulativo osteopático é seguro para o feto e para gestantes portadoras de comorbidades, não afetando os sinais vitais maternos e nem a circulação uteroplacentária e feto-placentária. Os dados também apontaram que o tratamento osteopático foi eficaz na redução da intensidade da dor lombar e pélvica e efetivo na melhora da qualidade de vida das gestantes.

During pregnancy, several changes women undergo can affect their health status. Studies related to the inability of the body of some pregnant women to accommodate uterine growth would be at the root of problems in maternal-fetal hemodynamics. The search for non-drug treatments has grown in the health area recently. Manipulative osteopathic treatment is a complementary, integrative health therapy recognized by the world health organization and accepted by the Brazilian single health system. Method: This prospective cohort study was carried out with 80 patients from the prenatal clinic and the pregnant women's ward of Instituto Fernandes Figueira/Fiocruz between July 2021 and September 2022. Two studies were carried out, a cross-sectional study with 51 pregnant women to evaluate the maternal-fetal hemodynamic effects after osteopathic manipulative treatment through Doppler velocimetry in pregnant women and a prospective study with 64 pregnant women to evaluate the influence of osteopathic manipulative treatment on the intensity of lumbar and pelvic pain, as well as changes in their quality of life. Population: pregnant women in the third trimester of pregnancy, over 18 years old, were investigated, and pregnant women with premature membrane rupture, fetal malformations, multiple fetuses, and active labor were excluded. Results: The results of the cross-sectional study after manipulative treatment were not statistically significant. Pregnant women were divided into two groups ≤ 3 and ≥ 4 in the prospective study. There was a statistically significant improvement in lumbar and pelvic pain intensity in both groups. There was an improvement in both groups in the quality-of-life indices, and in the group≥ four consultations, all results were statistically achieved. Conclusion: an analysis of the study data found that osteopathic manipulative treatment is safe for the fetus and pregnant women with comorbidities, not affecting maternal signs or uteroplacental and fetal-placental circulation. The data also showed that osteopathic treatment effectively reduced the intensity of lumbar and pelvic pain and improved the quality of life of pregnant women.

Transmisión vertical de Toxoplasma gondii asociado a la edad gestacional / Vertical transmission of Toxoplasma gondii associated with gestational age

Una de las principales consecuencias de la infección por Toxoplasma gondii en mujeres embarazadas es la transmisión vertical al feto. Aunque es poco frecuente, la toxoplasmosis congénita puede causar enfermedades neurológicas u oculares graves. La infección primaria por T. gondii durante el embarazo puede tener consecuencias peligrosas, como retinocoroiditis, hidrocefalia, calcificaciones cerebrales, encefalitis, esplenomegalia, pérdida de audición, ceguera y muerte. La atención prenatal debe incluir educación sobre la prevención de la toxoplasmosis. Se trata de un estudio observacional, analítico y transversal. Se evaluaron 209 mujeres gestantes e igual número de recién nacidos; 136 de las mujeres embarazadas resultaron con infección aguda positiva a IgM. De estas 51,20% y 64,71% resultaron primoinfectadas según la determinación de IgA e IgG avidez, respectivamente. 20 de los 35 neonatos provenientes de madres primoinfectadas, adquirieron la infección congénita en el tercer trimestre de la gestación. La conciencia sobre la prevención y el control de la toxoplasmosis es baja entre las poblaciones de alto riesgo. Es necesario fortalecer la educación en salud relacionada con la prevención y el control de la toxoplasmosis en las mujeres en edad reproductiva para prevenir la transmisión vertical a sus productos de gestación y evitar los efectos negativos y hasta mortales de la inefcción por el parásito(AU)

One of the main consequences of Toxoplasma gondii infection in pregnant women is vertical transmission to the fetus. Although rare, congenital toxoplasmosis can cause serious neurological or ocular disease. Primary T. gondii infection during pregnancy can have dangerous consequences, including retinochoroiditis, hydrocephalus, cerebral calcifications, encephalitis, splenomegaly, hearing loss, blindness, and death. Prenatal care should include education on the prevention of toxoplasmosis. This is an observational, analytical and cross-sectional study. 209 pregnant women and the same number of newborns were evaluated; 136 of the pregnant women were acutely infected with IgM. Of these, 51.20% and 64.71% were primary infected according to the determination of IgA and IgG avidity, respectively. 20 of the 35 neonates from mothers with primary infection acquired the congenital infection in the third trimester of pregnancy. Awareness of toxoplasmosis prevention and control is low among high-risk populations. It is necessary to strengthen health education related to the prevention and control of toxoplasmosis in women of reproductive age to prevent vertical transmission to their gestational products and avoid the negative and even fatal effects of infection by the parasite(AU)

Supresión de la visita de tercer trimestre en embarazo de bajo riesgo en la pandemia de SARS-CoV-2 / Third trimester suppression in low-risk pregnancy in the SARS-CoV-2 pandemic

Resumen Objetivo: La pandemia de SARS-CoV-2 ha obligado a una reorganización de las visitas presenciales, y por ese motivo se han minimizado hasta el punto de reconsiderar la realización de la visita del tercer trimestre. Nuestro centro suprimió dicha visita obstétrica y obtuvo datos propios para comparar los resultados perinatales logrados con dicho manejo. Método: Se realizó un estudio de cohortes retrospectivo, en marzo de 2020, con una cohorte con visita presencial única en la semana 40 de gestación (122 gestantes) frente a una cohorte con seguimiento convencional con visita presencial en la semana 36 de gestación (162 gestantes). Se evaluaron la restricción del crecimiento fetal, la edad gestacional al nacimiento, el peso neonatal y las tasas de inducciones, partos eutócicos y cesáreas urgentes en trabajo de parto. Resultados: Se encontraron diferencias leves en la tasa de nuliparidad (p < 0,04), sin hallarlas en el resto de las variables maternas. No hubo diferencias entre las dos cohortes en los resultados neonatales. Conclusiones: No hay diferencias entre los resultados materno-fetales obtenidos en gestantes con seguimiento gestacional con restricción de la visita del tercer trimestre respecto del seguimiento tradicional, excepto en el diagnóstico de las alteraciones de la estática fetal al término de la gestación.

Abstract Objective: The SARS-CoV-2 pandemic has forced a reorganization of face-to-face visits, for this reason they have been minimized to the point of reconsidering the completion of the third trimester visit. Our center eliminated the performance of this obstetric visit and obtained its own data to compare the perinatal results obtained with such management. Method: A retrospective cohort study was carried out in March 2020, with a cohort with a single face-to-face visit at 40th week of gestation (122 pregnant women), versus a cohort with conventional follow-up with face-to-face visit at 36th week of gestation (162 pregnant women). The following were evaluated fetal growth restriction, gestational age at birth, neonatal weight, rate of inductions, of eutocic deliveries, and of urgent cesarean sections in labor. Results: Slight differences were found in the nulliparity rate (p < 0.04), without finding them in the rest of the maternal variables. There were no differences between the two cohorts in neonatal outcomes. Conclusions: There were no differences between the maternal-fetal results obtained in pregnant women with gestational follow-up with restriction of the third trimester visit compared to traditional follow-up, except in the diagnosis of alterations in fetal statics at the end of pregnancy.

Analysis of antepartum cardiotocography based on S/k proportions and probability in 20 minutes / Análisis de la cardiotocografía anteparto mediante las relaciones S/k y la probabilidad en 20 minutos

Abstract Objectives: although mortality and perinatal asphyxia in newborns have been considerably reduced, there are still deficiencies in screening and diagnosis methods for intrapartum fetal well being that aim to detect its early alterations. Therefore, the purpose of this research was to apply a methodology based on probability and entropy and confirm its capacity to detect normal and abnormal fetal cardiac dynamics from 20-minute cardiotocographic tracings. Methods: 80 cardiotocographic tracings of pregnant women in the last trimester were collected, of which the minimum and maximum fetal heart rate were evaluated every 10 seconds, as well as its repetitions along with their probability and the diagnostic S/k ratio. Finally, the statistical analysis was carried out to establish the diagnostic capacity of the method concerning the clinical evaluation and interpretation of the cardiotocographic tracing, taken as the Gold Standard. Results: it was confirmed that S/k ratio values differentiated normal from abnormal fetal cardiac dynamics with sensitivity and specificity values of 100% and a Kappa coefficient of 1. Conclusion: the applicability of a diagnostic mathematical method of cardiotocography was confirmed, which suggests its implementation in the clinical context to detect alterations in fetal well-being in 20 minutes.

Resumo Objetivos: aunque se ha logrado reducir considerablemente la mortalidad y asfixia perinatal en neonatos, aún hay deficiencias en los métodos de tamizaje y diagnóstico del bienestar fetal intraparto que detecten sus alteraciones tempranas. Por lo anterior, el propósito de esta investigación fue aplicar una metodología basada en la probabilidad y la entropía y confirmar su capacidad para diagnosticar la dinámica cardíaca fetal normal de la anormal a partir de trazados cardiotocográficos de 20 minutos. Métodos: se recolectaron 80 trazados cardiotocográficos de gestantes en el último trimestre, de los cuales se evaluaron frecuencia cardíaca fetal mínima y máxima cada 10 segundos al igual que sus repeticiones, su probabilidad y la proporción S/k diagnóstica. Finalmente, se realizó un análisis estadístico para establecer la capacidad diagnóstica del método con respecto a la interpretación el trazado cardiotocográfico y la evaluación clínica, tomadas como Gold Standard. Resultados: se confirmó que los valores de la proporción S/k diferenciaron las dinámicas cardíacas fetales normales de las anormales con valores de sensibilidad y especificidad del 100% y un coeficiente Kappa de 1. Conclusión: se confirmó la aplicabilidad de un método matemático diagnóstico de la cardiotocografía, lo cual sugiere que su implementación en la clínica para detectar alteraciones del bienestar fetal en 20 minutos.

Conocimiento y conductas sexuales de las mujeres gestantes / Knowledge and sexual behaviors of pregnant women / Conhecimento e comportamentos sexuais de mulheres grávidas

Introducción: escasos son los estudios que investigan el conocimiento sexual y las conductas sexuales de las mujeres dentro de un periodo tan importante como lo es el embarazo. En esta etapa se producen una serie de cambios que repercuten en su vida y por lo tanto en su sexualidad, por tal motivo es que surge realizar este trabajo de investigación. Objetivo: evaluar el nivel de conocimiento y conducta sexual durante la gestación, en un grupo de gestantes que acuden al Centro de Atención Periférica Número 8 perteneciente a la Dirección General de Atención Periférica de la Dirección Nacional de Sanidad de la Fuerzas Armadas. Materiales y métodos: se realizó un análisis observacional, descriptivo y prospectivo de cohorte transversal de los datos obtenidos a través de entrevistas realizadas a embarazadas. Se entrevistan gestantes que cursan los tres trimestres de embarazo y concurren a sus controles obstétricos en el periodo comprendido entre el 22 de abril y 22 de julio de 2021 que cumplen con los criterios de inclusión y exclusión. Para alcanzar el objetivo se aplicó un cuestionario con respuestas cerradas que consta de 11 preguntas basadas en conocimientos y conductas sexuales en gestantes. Resultados: el 52% de nuestras pacientes gestantes encuestadas tienen más de 30 años, 52% cursa su primera gestación y 51% un embarazo no deseado, pero si aceptado. El 61% de ellas dicen que el estar embarazadas afectó su actividad sexual, 39% refiere que son más satisfactorias las relaciones sexuales en el segundo trimestre, 78% manifiesta que el mantener relaciones sexuales no adelanta el parto, el 83% expresa que la posición menos recomendada es boca arriba, el 9% no saben dónde se localiza el tapón mucoso y el 100% de las encuestadas no tuvo educación sobre sexualidad en los controles prenatales. Conclusiones: durante el embarazo se producen cambios anatómicos, psicológicos y emocionales que provocan cambios en la actividad sexual. La educación que tienen sobre sexualidad es nula por lo que es recomendable la implementación de programas formativos de educación sexual en gestantes y sus parejas para afrontar una salud sexual plena.

Introduction: there are few studies that investigate the sexual knowledge and sexual behaviors of women in such an important period as pregnancy. During this stage, a series of changes take place that have repercussions in their lives and therefore in their sexuality, which is the reason why this research work has been carried out. Objective: to evaluate the level of knowledge and sexual behavior during pregnancy in a group of pregnant women attending the Peripheral Care Center Number 8 belonging to the General Directorate of Peripheral Care of the National Health Directorate of the Armed Forces. Materials and methods: an observational, descriptive and prospective cross-sectional cohort analysis of the data obtained through interviews with pregnant women was carried out. Pregnant women in the three trimesters of pregnancy and attending their obstetric check-ups between April 22 and July 22, 2021 who met the inclusion and exclusion criteria were interviewed. To achieve the objective, a questionnaire with closed answers consisting of 11 questions based on knowledge and sexual behaviors in pregnant women was applied. Results: 52% of our pregnant patients surveyed were over 30 years of age, 52% were in their first pregnancy and 51% had an unwanted pregnancy, but accepted it. 61% of them said that the pregnancy was unwanted. Sixty-one percent of them say that being pregnant affected their sexual activity, 39% say that sexual relations are more satisfactory in the second trimester, 78% say that having sexual relations does not advance labor, 83% say that the least recommended position is on the back, 9% do not know where the mucus plug is located and 100% of the respondents had no education on sexuality in prenatal checkups. Conclusions: During pregnancy there are anatomical, psychological and emotional changes that cause changes in sexual activity. The education they have about sexuality is null, so it is advisable to implement sex education programs for pregnant women and their partners in order to achieve full sexual health.

ntroduction: The information concerning the impact of COVID-19 infection in pregnant people (PP) continues to be established.Aim: to describe the evolution of the Sars-CoV-2 infection in pregnant people and to determine variables associated with clinical severity.Materials and Methods: Retrospective observational study. Period: 01-03-2020 to 31-07-2021. We included PP with diagnosis of COVID-19, assisted in a public maternity hospital. The cases were classified according to clinical severity based on the NIH guidelines. The patients were divided into 2 groups: Group 1: mild (ambulatory manage-ment). Group 2: moderate, severe and critical (requiring hospitalization). The relationship between variables and clinical severity was analyzed. Variables studied: obesity, DBT, gestational hypertension, gestational age, maternal age, influenza vaccination. Newborns of infected mothers were studied with PCR for Sars-CoV-2 24 to 48 hours af-ter birth. Statistical analysis: Chi-square or Fisher's exact test, significance = p <0.05. Study approved by the Institu-tional Ethics Committee.Results: 52 PP with diagnosis of COVID-19 were includ-ed. Median age 29.6 years. 23 patients (44%) required hospitalization and 2 (4%) MRA (mechanical respiratory assistance). 29 (55.5%) were mild, 19 (36.5%) moderate, 2 (4%) severe, and 2 (4%) critical. There were no mater-nal or fetal deaths. Gestational age ≥ 28 weeks was the only variable associated with more severe clinical forms, p = 0.0001. 48% of the pregnancies ended by cesarean section. 48/52 newborns were studied with PCR for Sars-CoV-2, with only 1 (2%) being positive. This was the only symptomatic newborn.Conclusions: In our study, Sars-CoV-2 infection during pregnancy was associated with more severe clinical pre-sentations when the infection occurred in the 3rd trimes-ter of pregnancy. COVID-19 was also associated with a higher incidence of ter

Histerectomia radical após parto cesáreo por adenocarcinoma de colo uterino: relato de caso / Radical hysterectomy after c-section in cervical adenocarcinoma: a case report

Mundialmente, o câncer de colo uterino ocupa o quarto lugar das neoplasias em mulheres, porém, nos países em desenvolvimento, as taxas de incidência superam de forma impactante os casos de países desenvolvidos. Apesar de ser um evento incomum durante a gestação, é cada vez mais observado, o que talvez possa ser atribuído às gestações programadas em idades mais avançadas. O caso descrito refere-se a uma paciente de 32 anos de idade, diagnosticada no terceiro trimestre da gestação com adenocarcinoma de origem endocervical com estadiamento anatomopatológico final (FIGO 2018) 1B2. Ela foi submetida à abordagem cirúrgica como tratamento inicial. Foi adotada como conduta a resolução da gestação, com boa vitalidade fetal, ao final da 34ª semana, após corticoterapia para maturação pulmonar fetal. Foi realizado parto cesariano seguido de histerectomia radical tipo C1 na classificação de Querleu e Morrow associado a linfadenectomia pélvica, no mesmo ato operatório.(AU)

Worldwide, cervical cancer ranks fourth in female cancers, but when assessing data from developing countries, incidence rates are significantly higher than in developed countries. Although it is an uncommon event during pregnancy, it is increasingly observed, which may perhaps be justified due to pregnancies postponed at older ages. The case described relates to a 32-year-old woman diagnosed in the third trimester of pregnancy with endocervical adenocarcinoma, whose final anatomopathological staging (FIGO 2018) was IB2. The same was submitted to the surgical approach as an initial treatment. It was adopted as a conduct, the resolution of pregnancy, with good fetal viability, at the end of the 34th week, after corticosteroid therapy for fetal lung maturation. The patient underwent cesarean section followed by radical type C1 hysterectomy in the classification of Querleu and Morrow associated with pelvic lymphadenectomy in the same surgery.(AU)

Prenatal pyrethroid pesticides exposure and neurodevelopment of 2-year-old children: a birth cohort study / 中华预防医学杂志

Objective: To investigate the influence and critical windows of prenatal exposure to pyrethroid pesticides (PYRs) on neurodevelopment of 2-year-old children. Methods: The subjects of this study were derived from the Xuanwei Birth Cohort. A total of 482 pregnant women who participated in the rural district of Xuanwei birth cohort from January 2016 to December 2018 were included. Maternal urinary concentrations of PYRs metabolites during 8-12 gestational weeks, 20-23 gestational weeks and 32-35 gestational weeks were measured with ultra high performance liquid chromatography system coupled with a tandem mass spectrometry detector. Child neurodevelopment was evaluated with the Bayley Scales of Infant and Toddler Development-Third Edition at 2 years of age. Multivariate linear regression models and binary logistic regression models were used to assess the association between PYRs exposure during pregnancy and children's neurodevelopment. Results: A total of 360 mother-child pairs had complete data on maternal urinary PYRs metabolites detection and children's neurodevelopment assessment. The detection rate of any one PYRs metabolites during the first, second and third trimester were 93.6% (337/360), 90.8% (327/360) and 94.2% (339/360), respectively. The neurodevelopmental scores of Cognitive, Language, Motor, Social-Emotional, and Adaptive Behavior of 2-year-old children were (102.3±18.9), (100.2±16.3), (102.0±20.3), (107.8±23.3) and (85.8±18.6) points, respectively. After controlling for confounding factors, 4-fluoro-3-phenoxybenzoic acid (4F3PBA, one of PYRs metabolites) exposure in the first trimester reduced Motor (β=-5.02, 95%CI: -9.08, -0.97) and Adaptive Behavior (β=-4.12, 95%CI:-7.92, -0.32) scores of 2-year-old children, and increased risk of developmental delay of adaptive behavior (OR=2.07, 95%CI:1.13-3.82). Conclusion: PYRs exposure during the first trimester of pregnancy may affect neurodevelopment of 2-year-old children, and the first trimester may be the critical window.

Hemoglobina glucosilada en el diagnóstico de diabetes gestacional en mujeres mexicanas durante el tercer trimestre / Glycosylated hemoglobin in the diagnosis of gestational diabetes in Mexican women during the third trimester

Resumen El objetivo del trabajo fue analizar los valores de hemoglobina glucosilada en el tercer trimestre de embarazo como predictores alternativos de la diabetes gestacional en pacientes del Noreste de México. Se trata de un estudio retrospectivo de casos y controles a partir de 121 expedientes de pacientes embarazadas, divididos en dos grupos, pacientes con diabetes gestacional (casos) y gestantes con valores glucémicos normales (controles). Se analizaron los factores de riesgo asociados a la diabetes gestacional y se obtuvo un punto de corte para la hemoglobina glucosilada. Se encontró que la obesidad materna, la edad y el antecedente del padecimiento fueron asociados significativamente con la diabetes gestacional. Valores de hemoglobina glucosilada ≥5% incrementaron el riesgo de padecer diabetes mellitus gestacional 4 veces y, aunado a un factor de riesgo, la probabilidad se incrementó 7 veces. Se concluye que los valores de hemoglobina glucosilada en el tercer trimestre de embarazo podrían emplearse como prueba diagnóstica de la diabetes gestacional en pacientes del Noreste de México. Sin embargo, aunque las diferencias encontradas fueron estadísticamente significativas, los resultados se deben interpretar con cautela y requieren su confirmación con estudios que incluyan una muestra mayor.

Abstract The objective of this study was to analise glycosylated hemoglobin values in the third trimester of pregnancy as an alternative predictor of gestational diabetes in North East Mexican cohort patients. This is a retrospective case-control study based on 121 records of pregnant patients, divided into two groups, patients with gestational diabetes (cases) and pregnant women with normal glycemic values (control). The risk factors associated with gestational diabetes were analised and a cut-off point for glycosylated hemogestaglobin was obtained. It was found that maternal obesity, age and a history of the condition were significantly associated with gestational diabetes. Values of glycosylated hemoglobin ≥5% increased the risk of suffering from gestational diabetes 4 times, and coupled with a risk factor, the risk increased 7 times. It is concluded that glycosylated hemoglobin values in the third trimester of pregnancy could be used as a diagnostic test for gestational diabetes in patients from the North East of Mexico. Although the differences found were statistically significant, our results must be interpreted with caution and require confirmation by studies with a larger sample.

Resumo O objetivo deste estudo foi analisar os valores da hemoglobina glicada no terceiro trimestre de gestação como preditores alternativos do diabetes gestacional em pacientes na região nordeste do México. Trata-se de um estudo retrospectivo de casos e controles utilizando 121 prontuários de gestantes divididas em dois grupos; pacientes com diabetes gestacional (casos) e gestantes com valores de glicemia normais (controles). Foram analisados os fatores de risco associados a diabetes gestacional obtendo-se um ponto de corte para a hemoglobina glicada. Descobriu-se que a obesidade materna, idade e antecedentes da doença foram associados significativamente ao diabetes gestacional. Valores da hemoglobina glicada ≥ 5% aumentaram o risco de padecer diabetes mellitus gestacional 4 vezes, e juntamente a um fator de risco, a probabilidade aumentou 7 vezes. Conclui-se que os valores da hemoglobina glicada no terceiro trimestre de gestação poderiam ser usados como teste diagnóstico do diabetes gestacional em pacientes da região nordeste do México. Embora as diferenças encontradas tenham sido estatisticamente significativas, os resultados devem ser interpretados com cautela e requerem confirmação através de estudos que incluam uma amostra maior.

Relación entre el consumo materno de carne vacuna durante el embarazo y los niveles de ferritina en el cordón umbilical / Relationship between maternal beef consumption during pregnancy and umbilical cord ferritin concentration / Relação entre o consumo materno de carne bovina durante a gravidez e os níveis de ferritina no cordão umbilical

Antecedentes: la nutrición durante el embarazo impacta en la salud del recién nacido, con efectos a nivel epigenético determinando consecuencias neurológicas a largo plazo. Las necesidades de hierro durante el embarazo se estiman en 27 mg/día. El hierro hemo que se absorbe mejor se encuentra en la carne. La determinación de ferritina en sangre de cordón umbilical permite evaluar los depósitos de hierro alcanzados durante la etapa fetal. Sus niveles se asociaron con efectos a largo plazo sobre el desarrollo infantil. Objetivos: el objetivo de este estudio de carácter exploratorio es determinar la relación entre el consumo de carnes rojas durante el tercer trimestre de gestación y el nivel de ferritina en el cordón umbilical. Métodos: se realizó un estudio observacional descriptivo con datos recolectados prospectivamente durante un año en el Departamento de Neonatología del Centro Hospitalario Pereira Rossell (CHPR) en Montevideo, Uruguay. Un total de 188 pacientes cumplieron los criterios de inclusión. Se extrajo sangre del cordón umbilical después de un pinzamiento estricto del cordón pasado un minuto de vida. La ferritina se midió utilizando el método de quimioinmunofluorescencia. Se aplicó una encuesta nutricional materna (cualitativo-cuantitativa) que midió la frecuencia de consumo de alimentos con fuente de hierro y las cantidades aproximadas consumidas durante el último trimestre del embarazo. Esta encuesta se centró en el consumo materno de carne vacuna como principal fuente de hierro hemínico en Uruguay. Se analizó la relación entre estas variables. Resultados: el déficit latente de hierro (ferritina en el cordón umbilical <100 ng/ml) se asoció con un menor consumo de carne vacuna durante el embarazo. Valor p de Fisher: 0,0133, OR: 3,71, IC del 95% (1,25-11,05). Conclusiones: este estudio considera adecuada la evidencia que relaciona que los niveles bajos de consumo total de hierro y de carne vacuna durante el tercer trimestre de gestación determinarán un mayor riesgo de déficit latente de hierro y de ferritina medido en el cordón umbilical. Los niveles descendidos de ferritina en cordón umbilical se asocian con un mayor riesgo de efectos adversos a largo plazo sobre la mielinización y el desarrollo neurocognitivo.

Background: nutrition during pregnancy impacts the foetus and the newborn health, it has consequences at the epigenetic level and determines long-term neurological consequences. Iron requirements during pregnancy are estimated at 27 mg/day. Iron is blood absorption from is most efficient from beef. Umbilical cord blood ferritin levels can be used to assess iron deposits reached during the foetal stage. Ferritin levels are linked to the child's long-term development. Objective: this exploratory study's objective is to determine the relationship between beef consumption during the first quarter of pregnancy and ferritin levels in the umbilical cord. Methods: we carried out a descriptive, observational study with prospectively collected data for one-year at the Neonatology Department of the Pereira Rossell Hospital Center (CHPR) in Montevideo, Uruguay. A total of 188 patients met the inclusion criteria. We extracted umbilical cord blood after a strict cord clamping after one minute of life. Ferritin was measured using the chemoimmunofluorescence method. We carried out a maternal nutritional survey using a qualitative-quantitative method and measured the frequency and approximate quantity of iron source food consumption during the last quarter of pregnancy. This survey was focused on maternal beef consumption as the major heme iron source in Uruguay. We analyzed the relationship between these variables. Results: latent iron deficiency (ferritin in the umbilical cord <100 ng / ml) was associated with lower beef consumption during pregnancy. Fisher p-value: 0.0133, OR: 3.71, 95% CI (1.25 - 11.05). Conclusions: this study agrees with the evidence that shows that low levels of total iron and beef consumption during pregnancy determine an increased risk of latent iron deficiency and lower levels of ferritin in newborns, and therefore, greater risk of long-term adverse effects on myelination and neurocognitive development.

Contexto: a nutrição durante a gravidez tem impacto sobre a saúde do recém-nascido, com efeitos no nível epigenético, determinando consequências neurológicas a longo prazo. As necessidades de ferro durante a gravidez são estimadas em 27 mg / dia. O ferro heme de melhor absorção e aquele encontrado na carne vacuna. A determinação da ferritina no sangue do cordão umbilical permite avaliar os depósitos de ferro atingidos na fase fetal. Seus níveis foram associados a efeitos de longo prazo no desenvolvimento das crianças. Objetivos: o objetivo deste estudo exploratório é determinar a relação entre o consumo de carne vermelha durante o terceiro trimestre de gestação e o nível de ferritina no cordão umbilical. Métodos: foi realizado um estudo observacional descritivo com dados coletados prospectivamente durante um ano no Departamento de Neonatologia do Centro Hospitalar Pereira Rossell (CHPR) em Montevidéu, Uruguai. Um total de 188 pacientes cumpriram os critérios de inclusão. O sangue do cordão umbilical foi coletado após clampeamento estrito do cordão após um minuto de vida da criança. A ferritina foi medida pelo método de quimioimunofluorescência. Aplicamos um inquérito nutricional materno (qualitativo-quantitativo) que mediu a frequência de consumo de alimentos com fonte de ferro e as quantidades aproximadas consumidas durante o último trimestre da gravidez. Esta pesquisa enfocou o consumo materno de carne bovina como principal fonte de ferro heme no Uruguai. A relação entre essas variáveis foi analisada. Resultados: a deficiência latente de ferro (ferritina no cordão umbilical <100 mg / ml) foi associada ao menor consumo de carne bovina durante a gestação. Valor de p de Fisher: 0,0133, OR: 3,71, IC 95% (1,25-11,05). Conclusões: este estudo concorda com as evidências que relacionam que os baixos níveis de ferro total e consumo de carne bovina durante o terceiro trimestre de gestação determinam um maior risco de déficit de ferro latente e ferritina mensurado no cordão umbilical. A redução dos níveis de ferritina no cordão umbilical está associada a um risco aumentado de efeitos adversos de longo prazo na mielinização e no desenvolvimento neurocognitivo.

Colecistectomía laparoscópica durante el embarazo, experiencia de un hospital universitario del noreste de México / Laparoscopic cholecystectomy during pregnancy, experience from a University Hospital in northeast Mexico

Resumen Objetivo: Evaluar la seguridad de la colecistectomía laparoscópica durante el embarazo, reportando complicaciones y desenlaces obstétricos y perinatales en nuestra institución. Materiales y Método: Estudio retrospectivo, observacional. Se incluyeron pacientes embarazadas, con diagnóstico de patología biliar sometidas a colecistectomía laparoscópica. Se describieron variables sociodemográficas, obstétricas, complicaciones o muerte posoperatoria. Resultados: Se realizaron 46 colecistectomías laparoscópicas, edad media de 25 años; 82,6% cursaban el segundo trimestre de embarazo; mostrando tasa de complicaciones de 4,4% directamente relacionadas con el procedimiento sin mortalidad materna. Discusión: Se asocia a la cirugía biliar a una tasa elevada de complicaciones durante el embarazo, sin embargo, existe mayor evidencia que apoya la idea de la intervención temprana en enfermedad biliar sintomática, con un mayor riesgo de muerte fetal bajo manejo conservador que bajo un abordaje quirúrgico, así como mayor tasa de recurrencia. Se ha demostrado que la cirugía no aumenta el riesgo de mortalidad para la madre y el feto y su retraso puede resultar en un incremento de morbilidad a corto y largo plazo. Conclusiones: Observamos una baja tasa de complicaciones asociadas al procedimiento quirúrgico, así como una nula mortalidad materna.

Aim: To evaluate the safety of laparoscopic cholecystectomy during pregnancy, reporting complications and obstetric and perinatal outcomes in our institution. Materials and Method: Retrospective, observational study. Pregnant patients with a diagnosis of biliary pathology undergoing laparoscopic cholecystectomy were included. Sociodemographic, obstetric variables, complications or postoperative death were described. Results: 46 laparoscopic cholecystectomies were performed, mean age 25 years; 82.6% were in the second trimester of pregnancy; showing a complication rate of 4.4% directly related to the procedure with zero maternal mortality. Discussion: Biliary surgery is associated with a high rate of complications during pregnancy, however, there is more evidence supporting the idea of early intervention in symptomatic biliary disease, with a higher risk of fetal death under conservative management than under a laparoscopic approach, 14 as well as a higher recurrence ratecd. Surgery has been shown not to increase the risk of mortality for the mother and the fetus and its delay may result in an increase in morbidity in the short and long term. Conclusión: We observed a low rate of complications associated with the surgical procedure, as well as no maternal mortality.

Severe polyhydramnios as neonatal presentation of Bartter's syndrome type IV / Polihidrâmnios grave como manifestação neonatal da síndrome de Bartter tipo IV

Abstract Introduction: Bartter's syndrome comprises a heterogeneous group of inherited salt-losing tubulopathies. There are two forms of clinical presentation: classical and neonatal, the most severe type. Types I and II account for most of the neonatal cases. Types III and V are usually less severe. Characteristically Bartter's syndrome type IV is a saltlosing nephropathy with mild to severe neonatal symptoms, with a specific feature - sensorineural deafness. Bartter's syndrome type IV is the least common of all recessive types of the disease. Description: the first reported case of a Portuguese child with neurosensorial deafness, polyuria, polydipsia and failure to thrive, born prematurely due to severe polyhydramnios, with the G47R mutation in the BSND gene that causes Bartter's syndrome type IV. Discussion: there are few published cases of BS type IV due to this mutation and those reported mostly have moderate clinical manifestations which begin later in life. The poor phenotype-genotype relationship combined with the rarity of this syndrome usually precludes an antenatal diagnosis. In the presence of a severe polyhydramnios case, with no fetal malformation detected, normal karyotype and after maternal disease exclusion, autosomal recessive diseases, including tubulopathies, should always be suspected.

Resumo Introdução: a síndrome de Bartter inclui um grupo heterogéneo de tubulopatias hereditárias perdedoras de sal. Existem duas formas de apresentação clínica: clássica e neonatal, a forma mais grave. Os tipo I e II representam a maioria dos casos neonatais. Os tipos III e V são geralmente menos graves. Caracteristicamente, a síndrome de Bartter tipo IV é uma nefropatia perdedora de sal com sintomas neonatais ligeiros a graves, com um aspeto especí- fico - surdez neurossensorial. A síndrome de Bartter tipo IV é o tipo menos comum das formas recessivas da doença. Descrição: relatamos o primeiro caso de uma criança portuguesa, com surdez neurossensorial, poliúria, polidipsia e restrição de crescimento, nascida prematuramente devido a polihidrâmnios grave, homozigótica para a mutação G47R do gene BSND, responsável pela síndrome de Bartter tipo IV. Discussão: são raros os casos publicados sobre síndrome de Bartter tipo IV atribuída a esta mutação, e a maioria referem-se a diagnósticos mais tardios, com manifestações clínicas ligeiras. A fraca correlação fenótipo-genótipo combinada com a raridade desta síndrome tornam o diagnóstico pré-natal desafiante. Perante um caso de polihidrâmnios grave em um feto sem malformações aparentes, cariótipo normal e após exclusão de patologia materna, as doenças autossómicas recessivas, incluindo as tubulopatias, devem ser sempre consideradas.

Evaluation of prenatal care according to indicators for the Prenatal and Birth Humanization Program / Avaliação da assistência pré-natal segundo indicadores do Programa de Humanização no Pré-natal e Nascimento

Abstract Objectives: to evaluate prenatal care provided to low-risk pregnant women users of the Sistema Único de Saúde (SUS) (Public Health System) in the city of Joinville, SC. Methods: this is a cross-sectional observational study carried out from March 2018 to February 2019, through interview and analysis of the Pregnant Card of puerperal over 18 years old, from Joinville, who underwent prenatal care at SUS, excluding recent given up puerperal. Prenatal care was evaluated according to the recommended criteria by the Prenatal and Birth Humanization Program. Results: 683 mothers were interviewed. The criteria with the highest levels of adequacy were accessibility (99.6%), early initiation on prenatal care (92.7%) and 6 or more consultations (87.1%) and the criteria with the lowest rates of adequacy were the set of guidelines (17.7%) and the third and first trimester exams (42.5% and 63.5% respectively). Conclusion: it is concluded that the prenatal care provided by SUS in the city of Joinville, despite the almost universal accessibility, the early onset and the prevalence of puerperal women with more than 6 consultations, showed a sharp decline in the analysis of the recommended indicators.

Resumo Objetivos: avaliar a assistência pré-natal prestada a gestantes de baixo risco usuárias do Sistema Único de Saúde da cidade de Joinville - SC. Métodos: trata-se de um estudo observacional transversal realizado de março de 2018 a fevereiro de 2019, mediante entrevista e análise do Cartão da Gestante de puérperas maiores de 18 anos, procedentes de Joinville, que realizaram o pré-natal no SUS, sendo excluídas puérperas desistentes. Avaliou-se a assistência pré-natal mediante critérios preconizados pelo Programa de Humanização no Pré-natal e Nascimento. Resultados: foram entrevistadas 683 puérperas. Os critérios com maiores índices de adequação foram acessibilidade (99,6%), início precoce do pré-natal (92,7%) e realização de 6 ou mais consultas (87,1%) e os critérios que apresentaram as menores taxas de adequação foram o conjunto de orientações (17,7%) e os exames do terceiro e primeiro trimestre (42,5% e 63,5% respectivamente). Conclusão: conclui-se que a assistência pré-natal realizada pelo SUS da cidade de Joinville, não obstante da acessibilidade praticamente universal, do início precoce e da prevalência de puérperas com mais de 6 consultas, demonstrou declínio acentuado na análise dos indicadores preconizados.

Prevalence and clinical significance of fetal tricuspid regurgitation during the third trimester of pregnancy / Prevalência e significado clínico da regurgitação tricúspide em fetos no terceiro trimestre da gestação

Abstract Objectives: the aim of this study was to determine the prevalence of fetal tricuspid valve regurgitation (TR) during the third trimester of low-risk pregnancies and to assess its clinical significance on neonates. Methods: this is a cross-sectional study including 330 singleton fetuses referred for routine fetal echocardiography during 3rd trimester in a fetal medicine center in Recife, Brazil. The presence and degree of tricuspid regurgitation were analyzed. Whenever TR was identified on fetal echocardiography, postnatal data, including the results of postnatal echocardiography were reviewed. Results: the prevalence of tricuspid regurgitation was 10.0% (n=33) in the study population. Regarding regurgitation degree, 90.9% (n=30) presented mild regurgitation and none presented important TR. Postnatal data was obtained from 21 neonates. Twenty of them were discharged without any complications, and one presented respiratory distress due to prematurity. Transthoracic echocardiography was performed in 66.7% (n=14) of the neonates and it was normal in 92.9% (n=13) of them. One neonate, 7.1%, persisted with tricuspid regurgitation, but had no other findings. Conclusions: tricuspid regurgitation in fetuses with normal cardiac anatomy during the 3rd trimester is a common condition in low-risk pregnancies, and is not associated with cardiac abnormalities or need for neonatal intervention.

Resumo Objetivos: determinar a prevalência da regurgitação tricúspide (RT) em fetos no terceiro trimestre de gestações de baixo risco e investigar sua repercussão clínica nos recémnascidos. Métodos: trata-se de um estudo transversal incluindo 330 fetos encaminhados para realização de ecocardiograma fetal de rotina no terceiro trimestre da gestação num centro de medicina fetal em Recife, Brasil. A presença e o grau de insuficiência tricúspide foram estudados. Quando RT estava presente ao ecocardiograma fetal dados pós-natais, incluindo ecocardiograma, também foram analisados. Resultados: a prevalência de RT foi de 10,0% na população estudada, sendo que 90,9% (n=30) dos casos foram classificados como RT leve, e nenhum caso de RT importante foi identificado. Foram obtidos dados pós-natais de 21 recém-nascidos. Destes, 20 receberam alta hospitalar sem nenhuma complicação, enquanto 1 apresentou desconforto respiratório associado à prematuridade. Ecocardiograma transtorácico foi realizado em 66.7% (n=14) dos recém-nascidos avaliados, e foi normal em 92.9% (n=13) deles. Apenas 1 recém-nascido, 7.1%, persistiu com RT mas sem outros achados significativos. Conclusões: a RT em fetos com anatomia cardíaca normal é comum no terceiro trimestre de gestações de baixo risco e não parece associar-se a anomalias cardíacas ou necessidade de intervenção no período neonatal.

Third trimester HbA1c and the association with large-for-gestational-age neonates in women with gestational diabetes

ABSTRACT Objective: To evaluate the association between HbA1c levels measured in the third trimester and the risk for large for gestational age (LGA) in neonates of mothers affected by gestational diabetes mellitus (GDM). Secondarily, we aimed to identify an ideal cut-off for increased risk of LGA amongst pregnant women with GDM. Materials and methods: Observational retrospective review of singleton pregnant women with GDM evaluated in a diabetes and pregnancy clinic of a tertiary and academic hospital. From January/2011 to December/2017, 1,085 pregnant women underwent evaluation due to GDM, of which 665 had an HbA1c test in the third trimester. A logistic regression model was performed to evaluate predictors of LGA. A receiver-operating-characteristic (ROC) curve was used to evaluate the predictive ability of third trimester HbA1c for LGA identification. Results: A total of 1,085 singleton pregnant women were evaluated during the study period, with a mean age of 32.9 ± 5.3 years. In the multivariate analysis, OGTT at 0 minutes (OR: 1.040; CI 95% 1.006-1.076, p = 0.022) and third trimester HbA1c (OR: 4.680; CI 95% 1.210-18.107, p = 0.025) were associated with LGA newborns. Using a ROC curve to evaluate the predictive ability of third trimester HbA1c for LGA identification, the optimal HbA1c cut-off point was 5.4% where the sensitivity was 77.4% and the specificity was 71.7% (AUC 0.782; p < 0.001). Conclusions: Few studies in the Mediterranean population have evaluated the role of HbA1c in predicting neonatal complications in women with GDM. A third trimester HbA1c > 5.4% was found to have good sensitivity and specificity for identifying the risk of LGA.

Resultados perinatales tras la suplementación de una cohorte de gestantes con vitamina D / Perinatal results after vitamin D supplementation in a pregnant women cohort

INTRODUCCIÓN Y OBJETIVOS: La deficiencia de vitamina D es muy prevalente durante la gestación, siendo cada vez más numerosos los estudios que relacionan esta condición con peores resultados perinatales. El objetivo del presente trabajo es describir los resultados perinatales y el curso del embarazo de una cohorte de gestantes deficitarias en vitamina D durante el primer trimestre del embarazo, suplementándolas con colecalciferol, así como establecer una comparación entre los resultados perinatales de aquellas pacientes con déficit o insuficiencia que lograron niveles normales de vitamina D en el tercer trimestre frente a aquellas que no lo lograron. Como objetivo secundario se describe el curso del embarazo de una cohorte de pacientes que durante el mismo periodo de tiempo del estudio presentaban normovitaminosis al inicio de la gestación. MÉTODOS: La cohorte de 190 pacientes analizada procede de casos consecutivos en la primera consulta de embarazo. Se determinaron los niveles de 25-hidroxivitamina D (25-OH-D) en la analítica del primer trimestre de 190 gestantes diferenciando entre valores normales (>30ng/mL), insuficiencia (30-15 ng/mL) y deficiencia (<15 ng/mL). Las pacientes con insuficiencia se suplementaron con 1000 UI/día de colecalciferol y las pacientes con deficiencia con 2000 UI/día. En el tercer trimestre se determinaron de nuevo los niveles de 25-OH-D en las pacientes suplementadas, suspendiendo la prescripción en caso de haberse normalizado los valores. Se comparan estadísticamente los resultados perinatales entre aquellas pacientes que mejoraron con la suplementación frente a aquellas que no lo hicieron. RESULTADOS: De las 190 pacientes analizadas, un 45% presentaban insuficiencia; un 27,5% deficiencia; y un 27,5% valores normales. De forma global, un 61% de las pacientes suplementadas habían normalizado sus niveles de vitamina D en la analítica del tercer trimestre, suspendiéndose la prescripción. De ese 61% normalizado, un 63% pertenecían al grupo de insuficiencia y un 37% al de deficiencia. Dentro del grupo suplementado con colecalciferol, un 1,4% de las pacientes desarrollaron hipertensión arterial, mientras que un 33% desarrollaron diabetes en el embarazo, de las cuales un 87% la controlaron exclusivamente con dieta y un 13% precisaron insulina. Un 3,6% de las gestaciones cursaron con retraso del crecimiento y la tasa de prematuridad fue igualmente del 3,6%. La tasa de cesáreas fue del 23%, de las cuales un 77% fueron indicadas intraparto y un 23% cesáreas programadas. El peso medio al nacimiento fue 3205g. Dentro del grupo con valores normales de 25-OH-D en el primer trimestre de la gestación, ninguna paciente desarrolló hipertensión arterial, mientras que un 15% presentaron diabetes gestacional controlada con dieta. Un 3,8% de dichas gestaciones cursaron con retrasos del crecimiento y la tasa de prematuridad fue del 1,9%. La tasa de cesáreas fue del 23%, de las cuales un 50% fueron indicadas intraparto y el 50% restante programadas. El peso medio al nacimiento fue de 3280g. En el análisis comparativo de los resultados perinatales entre el grupo de pacientes suplementadas que normalizaron sus cifras de vitamina D y aquellas que no lo hicieron, no se hallan diferencias estadísticamente significativas para ninguno de los parámetros analizados. CONCLUSIONES: La elevada tasa de hipovitaminosis D en la muestra analizada apoya la extensión del cribado y suplementación a todas las embarazadas y no solamente a aquellas con factores de riesgo. Dado que no se observaron diferencias estadísticamente significativas entre los niveles de vitamina D en el tercer trimestre y las variables perinatales estudiadas, podemos concluir que en nuestro estudio la suplementación con vitamina D no se ha comportado como factor protector de eventos obstétricos adversos.

INTRODUCTION AND OBJECTIVES: Vitamin D deficiency is highly prevalent during pregnancy, with an increasing number of studies linking this condition with worse perinatal outcomes. The objective of this present work is to describe the perinatal results and the course of pregnancy in a cohort of pregnant women deficient in vitamin D during the first trimester of pregnancy, supplementing them with cholecalciferol, as well as to establish a comparison between perinatal results of those patients with deficiencnieve or insufficiency who achieved normal levels of vitamin D in the third trimester compared to those who did not. As a secondary objective, the course of pregnancy is described in a cohort of patients who presented normal levels at the beginning of gestation during the same period of time of the study. METHODS: The cohort of 190 patients analyzed comes from consecutive cases in the first pregnancy visit. The levels of 25-hydroxyvitamin D (25-OH-D) were determined in the analysis of the first trimester of 190 pregnant women, differentiating between normal values (> 30ng / mL), insufficiency (30-15 ng / mL) and deficiency (<15 ng / mL). Patients with insufficiency were supplemented with 1000 IU/day of cholecalciferol and patients with deficiency with 2000 IU/day. In the third trimester, the 25-OH-D levels were determined again in the supplemented patients, suspending the prescription if the values had normalized. Perinatal outcomes are statistically compared between those patients who improved with supplementation versus those who did not. RESULTS: Of the 190 patients analyzed, 45% had insufficiency; 27.5% deficiency; and 27.5% normal values. Overall, 61% of the supplemented patients had normalized their vitamin D levels in the third trimester analysis, suspending the prescription. Within that 61% normalized, 63% belonged to the insufficiency group and 37% to the deficiency group. In the group supplemented with cholecalciferol, 1.4% of the patients developed arterial hypertension, while 33% developed diabetes in pregnancy, of which 87% controlled it exclusively with diet and 13% required insulin. 3.6% of pregnancies had intrauterine growth restriction and the prematurity rate was also 3.6%. The caesarean section rate was 23%, of which 77% were indicated intrapartum and 23% scheduled caesarean sections. The mean weight at birth was 3205g. Within the group with normal 25-OH-D values in the first trimester of pregnancy, no patient developed hypertension, while 15% had diet-controlled gestational diabetes. 3.8% of these pregnancies had intrauterine growth restriction and the prematurity rate was 1.9%. The cesarean section rate was 23%, of which 50% were indicated intrapartum and the remaining 50% scheduled. The mean weight at birth was 3280g. In the comparative analysis of the perinatal results between the group of supplemented patients who normalized their vitamin D levels and those who did not, no statistically significant differences were found for any of the parameters analyzed. CONCLUSIONS: The high rate of hypovitaminosis D in the analyzed sample supports the extension of screening and supplementation to all pregnant women and not only to those with risk factors. Since no statistically significant differences were observed between vitamin D levels in the third trimester and the perinatal outcomes studied, we can conclude that in our study vitamin D supplementation has not behaved as a protective factor against adverse obstetric events.
