¿Afecta la infección asintomática, leve y moderada por Covid-19 en el primer y segundo trimestre los resultados del embarazo?

Objetivo : Determinar los efectos de la infección Covid-19 asintomática, leve y moderada en el primer y segundo trimestres en los resultados del embarazo. Métodos : El estudio se realizó en las gestantes que acudieron al Departamento de Perinatología de la Universidad de Ciencias de la Salud de Izmir entre octubre de 2021 y julio de 2022. Se registraron las mujeres embarazadas que presentaban infección asintomática, leve y moderada por Covid-19 en el 1º y 2º trimestre y se siguió el desarrollo de la gestación. Resultados : Un total de 437 pacientes participaron en el estudio. El número de pacientes asintomáticos, leves y moderados de Covid-19 fue de 142, 157 y 138, respectivamente. Cada grupo se analizó como subgrupo del 1º y 2º trimestre según el momento de la infección por Covid-19. La edad media de las pacientes con Covid-19 moderado era superior a la de las pacientes con Covid-19 leve/asintomático (p=0,021). Se observó que el índice de masa corporal era mayor en las pacientes con Covid-19 moderado que en las pacientes con infección leve/asintomática (p=0,048). El parto pretérmino (entre las semanas 34 y 37) fue significativamente mayor en los casos con infección moderada por Covid-19 (p=0,041). Este aumento ocurrió principalmente en pacientes con infección por Covid-19 en el 2º trimestre. No hubo modificaciones significativas en las tasas de cesárea, trastornos hipertensivos del embarazo, pérdida fetal, retraso del crecimiento intrauterino, colestasis del embarazo y diabetes gestacional. Conclusiones : Los efectos de la infección por Covid-19 al inicio del embarazo (1º y 2º trimestres) siguen siendo objeto de investigación. La infección moderada por Covid-19, especialmente en el 2º trimestre, puede provocar un aumento de la tasa de partos prematuros.

Objectives: To evaluate the effects of asymptomatic, mild and moderate Covid-19 infection in the 1st and 2nd trimesters on pregnancy outcomes. Material and methods: The study was performed among patients who applied to the Perinatology Department of Izmir University of Health Sciences, between October 2021 and July 2022. Pregnant women who had asymptomatic, mild and moderate Covid-19 infection in the 1st and 2nd trimesters were registered and their pregnancy processes were followed. Results: A total of 437 patients participated in the study. The numbers of asymptomatic, mild and moderate Covid-19 patients were 142, 157 and 138, respectively. Each group was analyzed as 1st and 2nd trimester subgroups according to the time of Covid-19 infection. The mean age of patients with moderate Covid-19 was higher than with mild/asymptomatic Covid-19 (p=0.021). Body mass index was found to be higher in patients with moderate Covid-19 compared to patients with mild/asymptomatic infection (p=0.048). Preterm labor (between 34th and 37th weeks) was significantly higher with moderate Covid-19 infection (p=0.041). This significant increase was mainly due to the preterm birth rate in patients with previous Covid-19 infection in the 2nd trimester. There was no significant change in the rates of cesarean section, hypertensive disorders of pregnancy, fetal loss, intrauterine growth restriction, cholestasis of pregnancy and gestational diabetes. Conclusions: The effects of Covid-19 infection in early pregnancy (1st and 2nd trimester) are still the subject of research. Moderate Covid-19 infection, especially in the 2nd trimester, may lead to an increase in the rate of preterm birth.

Can Prenatal and Postnatal Cell Phone Exposure Increase Adverse Maternal, Infant and Child Outcomes? / A exposição pré-natal e pós-natal a telefones celulares pode aumentar os resultados adversos para mães, bebês e crianças?

Abstract Objective To determine the association between maternal mobile phone use and adverse outcomes in infants, children, and mothers. Method In March 202, we conducted a search on the MEDLINE, Embase, and Scopus databases. Data extraction and an assessment of the quality of the studies were performed by two authors. The quality of the studies was assessed using the checklist of the Newcastle-Ottawa scale. Results Studies assessing behavioral problems in infants aged 6 to 18 months reported null findings. However, an increased risk of emotional and behavioral disorders was observed in children aged between 7 and 11 years whose mothers had been exposed to cell phones. The findings regarding the association between maternal cell phone exposure and adverse outcomes in children aged 3 to 5 are controversial. A study found a significant association between the call time (p=0.002) or the history of mobile phone use (in months) and speech disorders in the children (p=0.003). However, another study found that maternal cell phone use during pregnancy was not significantly associated with child psychomotor and mental developments. Inconclusive results were observed about the adverse outcomes in fetuses, such as fetal growth restriction or t scores for birth weight in cell phone users as opposed to non-users. On the contrary, the children ofmothers who were cell phone users had a lower risk of scoring low on motor skills. Similar results were observed regarding the adverse outcomes of cell phone use in infants, such as fetal growth restriction or low birth weight, and the risk of preeclampsia was lower among subjects with medium and high cell phone exposure, as opposed to those with low exposure. Conclusion Studies on behavioral problems have reported different postnatal results, such as null findings among infants and a positive association in children.

Resumo Objetivo Determinar a associação entre o uso de telefone celular pela mãe e os resultados adversos em recém-nascidos crianças e mães. Método Em março de 2020 realizou-se uma pesquisa nas bases de dados MEDLINE, Embase e Scopus. A extração de dados e avaliação da qualidade dos estudos foram realizadas por dois autores. A qualidade dos estudos foi avaliada por meio da lista de verificação da escala Newcastle-Ottawa. Resultados Estudos que avaliavam problemas comportamentais em recém-nascidos de 6 a 18 meses relataram resultados nulos. No entanto um risco aumentado de transtornos emocionais e comportamentais foi observado em crianças de 7 a 11 anos de idade cujas mães foram expostas a telefones celulares. Os resultados relacionados à associação entre a exposição materna a celulares e resultados adversos em crianças de 3 a 5 anos são controversos. Um estudo encontrou associação significativa entre o tempo de ligação (p=0.002) ou o histórico de uso de celular (emmeses) e distúrbios de fala nas crianças (p=0.003). No entanto outro estudo descobriu que o uso de telefone celular pela mãe durante a gravidez não estava significativamente associado ao desenvolvimento psicomotor e mental da criança. Resultados inconclusivos foram observados com relação aos resultados adversos de fetos como restrição de crescimento intrauterino ou valores de t para peso ao nascer em usuárias de telefone celular em oposição a não usuárias. Pelo contrário os filhos de mães usuárias de telefone celular apresentaram menor risco de pontuação baixa em habilidades motoras. Resultados semelhantes foram observados com relação a resultados adversos em recém-nascidos como restrição de crescimento intrauterino ou valores de peso ao nascere o risco de pré-eclâmpsia foimenor em indivíduos comexposição média e alta a celulares em oposição àqueles com baixa exposição. Conclusão Estudos sobre problemas comportamentais relataram resultados diferentes no pós-natal como achados nulos em recém-nascidos e associação positiva emcrianças.

Desenlaces maternos y neonatales relacionados con edad materna avanzada / Maternal and neonatal outcomes in advanced maternal age

Resumen OBJETIVO: Describir los desenlaces maternos y perinatales en embarazadas de edad avanzada. MATERIALES Y MÉTODOS: Estudio de dos cohortes, prospectivo y retrospectivo efectuado con base en la información de expedientes clínicos de pacientes atendidas en el Complexo Hospitalario Universitario de Ourense entre 2017 y 2018. Se establecieron dos cohortes: la cohorte A con edad mayor o igual a 40 años y la cohorte B con edad menor de 40 años. Se realizaron pruebas paramétricas y no paramétricas para determinar la asociación potencial entre las variables de estudio (χ2, t de Student, U de Mann-Whitney). RESULTADOS: Las pacientes de la cohorte A (n = 207) tuvieron significación estadística: índice de masa corporal mayor al inicio del embarazo (p = 0.028), mayor cantidad de embarazos previos (p = 0.001), a expensas de mayor cantidad de abortos (p < 0.001), estados hipertensivos del embarazo (p = 0.03), prematurez (p = 0.009), retraso en el crecimiento intrauterino (p = 0.006), macrosomía fetal (p = 0.04), inducciones (p < 0.001), cesáreas programadas o intraparto y hemorragia posparto (p = 0.001). No se encontraron diferencias en la paridad, amenorrea al parto, diabetes pregestacional-gestacional, peso fetal medio, Apgar, pH de la arteria umbilical y cantidad de recién nacidos con requerimiento de ingreso a la unidad de Neonatología. CONCLUSIONES: La edad materna avanzada es un factor de riesgo importante de morbilidad materna y perinatal. La mayor tasa de complicaciones descritas refleja la importancia del control exhaustivo del embarazo y vigilancia periparto minuciosa.

Abstract OBJECTIVE: To describe the maternal and perinatal results in pregnant women with advanced age. MATERIALS AND METHODS: A cohort study was conducted with prospective follow-up and retrospective data collection of the Clinical History of the University Hospital Complex of Ourense between 2017 and 2018. Two cohorts were established, cohort A with age greater than and equal to 40 years and the cohort B with age under 40 years. Parametric and non-parametric tests were performed to determine the potential association between the study variables (Chi-Square, Student's T, Mann-Whitney U). RESULTS: The cohort A patients (n = 207) presented with statistical significance: body mass index higher at the beginning of pregnancy (p = 0.028), higher number of previous pregnancies (p = 0.001), but at the expense of a higher number of abortions (p <0.001), hypertensive states of pregnancy (p = 0.03), prematurity (p = 0.009), intrauterine growth retardation (p = 0.006), fetal macrosomia (p = 0.04), inductions (p < 0.001), of both scheduled and intrapartum caesarean sections and postpartum hemorrhage (p = 0.001). No differences were found in parity, amenorrhea at delivery, pregestational / gestational diabetes, mean fetal weight, Apgar score, umbilical artery pH and number of newborns who required admission to the Neonatal Unit. CONCLUSIONS: Advanced maternal age is an important risk factor for maternal and perinatal morbidity. The higher rate of complications described reflects the importance of thorough pregnancy control and careful peripartum surveillance.

Proteína plasmática A asociada al embarazo y fracción β de gonadotrofina coriónica humana en pacientes con resultados materno y perinatal adverso: informe preliminar / Plasma protein associated with pregnancy and β fraction human chorionic gonadotropin results in patients with adverse maternal and perinatal: preliminary report

Objetivo: Evaluar el comportamiento de marcadores bioquímicos: proteína plasmática asociada al embarazo (PAPP-A) y fracción β de la hormona gonadotrofina coriónica (β hCG) con resultado materno y perinatal adverso en el Hospital “Dr. Adolfo Prince Lara”. Métodos: Estudio prospectivo, comparativo en 35 gestantes con embarazos simples entre las 11 y 13 semanas + 6 días y resultado del embarazo conocido. Se realizó tamizaje combinado: traslucencia nucal, hueso nasal, ductus venoso, longitud craneocaudal y marcadores bioquímicos (PAPP-A y β -hCG). Se determinó la concentración de PAPP-A y β -hCG y sus resultados se expresaron en MoM. Variables cuantitativas fueron expresadas en media y desviación estándar (DE), cualitativas en porcentajes y se compararon estas variables entre el grupo de gestantes con resultado materno perinatal normal (RMPN) y adverso (RMPA) con la prueba U de Mann-Whitney. Resultados: 71 % tuvieron un RMPN y 29 % RMPA. No se encontraron diferencias entre los grupos respecto a edad materna, peso materno, IMC, paridad, presión arterial. La PAPP-A expresado en MoM presentan un valor más alto en las embarazadas que tuvieron un RMPA (1,07 vs 1,43) siendo estadísticamente significativo, los valores de β-HCG tuvieron valores más altos (0,60 vs 0,76) entre el grupo con RMPA en relación al grupo con RMPN sin llegar a la significancia estadística. Conclusión: Valores de la MoM PAPP-A difieren en las embarazadas con RMPA de aquellas con resultado normal, pero con valores mayores en las primeras, contrario a lo encontrado en la mayoría de las publicaciones estudiadas, iguales hallazgos con la β-hCG. Se debe profundizar en estos estudios para verificar los resultados encontrados.

Objective: To evaluate the behavior of biochemical markers PAPP-A and β hCG with adverse pregnancy and perinatal outcomes. Methods: Prospective, comparative study in 35 pregnant women with singleton pregnancies between 11 and 13 weeks + 6 days and outcome of pregnancy known. Nuchal translucency, nasal bone, ductus venosus, rump length and biochemical markers (PAPP-A and β-hCG) combined screening was performed. The concentration of PAPP-A and β-hCG was determined and the results were expressed in MoM. Quantitative variables were expressed as mean and standard deviation (SD), and these percentages qualitative variables between the group of pregnant women with a normal perinatal maternal outcome (NPMO) and adverse (AMPO) with the U Mann-Whitney test were compared. Setting: Hospital “Dr. Adolfo Prince Lara”. Results: 71 % had a NPMO and 29 % had an AMPO. No differences between the groups in respect of maternal age, maternal weight, BMI, parity, blood pressure were found. PAPP-A MoM have expressed a higher value in pregnant having an AMPO (1.07 vs 1.43) were statistically significant, the values of β-HCG had higher values (0.60 vs 0.76) between the group with AMPO relative to NMPO group without reaching statistical significance. Conclusion: MoM values of PAPP-A differ in pregnant with AMPO than in those with normal results, but with higher values in the first opposite to that found in most of the studied publications, the same findings with β-hCG. Thus, it should look into these studies to verify the results found.
