“… 28 29 Araya et al reported that age >35 years, delivery of more than two fetuses and <8 years of education were risk factors for PTB. 29 Women aged >35 years had longer exposure times to chronic pathologies and unhealthy lifestyles 30 and higher prevalence of maternal obesity in older mothers, which were associated with risk factors for PTB. 31 Several studies demonstrated that the lower the socioeconomic and education level, the higher the probability of developing infection, and that was clearly associated with PTB before 30 weeks of gestation.…”

ObjectiveAlthough vomiting in the first trimester has been reported to be associated with preterm birth (PTB), findings supporting this association remain inconsistent. Our aim was to assess the association between vomiting and PTB, as well as evaluate if the association is modified by pre-pregnancy body mass index (BMI).DesignA retrospective cohort study.SettingWuhan, a central city of China.ParticipantsA total of 317 463 pregnant women who had a live, singleton newborn from 1 January 2010 to 23 May 2016 were enrolled in our study.Main outcome measurePTB was defined as gestational age <37 gestational weeks. Gestational age was calculated using reports from mothers based on the first day of their last menstrual period. An ultrasound was routinely used to determine gestational age before 12 gestational weeks.ResultsOf the 317 463 pregnant women, 29.88% (94 857) experienced vomiting in the first trimester and 5.00% (15 889) experienced a PTB. Vomiting in the first trimester increased the risk for PTB and the multivariable adjusted OR was 1.05 (95% CI 1.02 to 1.09). In the stratified analyses, the association of vomiting in the first trimester was significant among underweight women (adjusted OR=1.08, 95% CI 1.04 to 1.17) and normal pre-pregnancy BMI women (adjusted OR=1.06, 95% CI 1.02 to 1.11), but not in overweight women (adjusted OR=1.01, 95% CI 0.90 to 1.14) and obese women (adjusted OR=0.93, 95% CI 0.73 to 1.19).ConclusionsOur study indicates that vomiting in the first trimester was associated with PTB. Additionally, women with underweight and normal pre-pregnancy BMI who experienced vomiting are more likely to have a PTB.

“…In this case, the adjusted risk of PTB were 45% higher for UM-FDA among the entire group of pregnant mothers and this effect did not differ across parity strata (p for this particular interaction term was 0.95). Since it has been shown that the socio-economic status is an important predictor of birth outcome and also of antenatal anxiety [42,43,44,45,46,47,48,49,50], all our analyses were adjusted for maternal employment and education, as well as the mother’s age and the sex of the child. There are no empirical studies, to our knowledge, which show the association between marital status and risk of preterm birth with respect to parity.…”

Uncertainty and insecurity in the relationship between the mother and father of a child are responsible for heightened maternal stress, which can lead to preterm birth (PTB). Different intensities of prenatal stress (proxied by four levels of marital status linked with the presence or absence of paternal data on birth records) were defined as the Marital-Father Data index. We assessed the impact of those varying intensities of prenatal stress on PTB with respect to parity among a group of Polish mothers residing in Krakow (N = 87,916). We found a pattern across the adjusted risk ratios (RR) of preterm birth that ordered these estimates in an increasing trend towards higher risk, beginning with the group of married mothers with father data present (baseline), through the groups of legitimizing marriages—married after conception with father data present (RR = 1.1; 95% Confidence Intervals (CI) 1.0–1.2) and unmarried mothers with father data present (RR = 1.3; 95% CI 1.2–1.5) to the group of unmarried mothers with father data absent (RR = 1.9; 95% CI 1.7–2.2). The adjusted p for the linear trend between Marital-Father Data index and PTB was less than 0.001. The adjusted effect of perceived prenatal stress differed with respect to parity (confirmed by statistically significant interactions between Marital-Father Data index levels and parity), with a higher magnitude of this effect noted among multiparous versus primiparous women. Low paternal involvement and support during pregnancy may negatively affect PTB risk and this effect may differ in relation to parity status. More attention should be paid to maternal pregnancy stress, especially of multiparous mothers, to decrease the risk of unfavorable birth outcomes.

“…Generar evidencia respecto a este tema es de suma importancia, ya que la prevalencia de los prematuros en Chile ha ido incrementando en los últimos años. Según el Departamento de Estadísticas Nacional, el porcentaje de recién nacidos menores a 37 semanas ha variado del 2010 al 2016 de 7.2 % a 8.3 % 12,30,31 .…”

Uso de sulfato de magnesio relacionado con la reanimación neonatal en prematuros

2022

View full text Add to dashboard Cite

Introducción: La neuroprotección farmacológica es utilizada en el periodo antenatal para ayudar a disminuir el riesgo de parálisis cerebral o disfunciones motoras en el recién nacido (RN). El sulfato de magnesio (MgSO4) es de gran utilidad por los beneficios que aporta como tocolítico, neuroprotector fetal en prematuros menores a 32 semanas y en el manejo de la preeclampsia. Sin embargo, durante su uso se han registrado efectos adversos a dosis dependientes tanto para la madre como para el RN, lo que genera gran importancia para la labor del profesional de obstetricia y enfermería. Objetivo: Determinar la frecuencia de reanimación neonatal en prematuros menores de 32 semanas según el uso de neuroprotección con MgSO4. Métodos: Estudio retrospectivo, observacional, realizado en un hospital de Santiago de Chile. Se realizó un muestreo aleatorio simple. Se incluyeron prematuros menores a 32 semanas de edad gestacional con o sin tratamiento de MgSO4 que hayan requerido o no reanimación neonatal. Se recolectó información desde fichas clínicas con un instrumento propio. Análisis de los datos mediante determinación de frecuencias absolutas y relativas de las variables y su comparación directa. Resultados: Del total de los RN que recibieron MgSO4, 61.7 % requirió reanimación neonatal al nacer, de los que no recibieron este neuroprotector, 52.8 % necesitó reanimación neonatal. Conclusiones: La mayor frecuencia de reanimación neonatal se asocia al uso de la neuroprotección con MgSO4 y ocurre más probablemente en neonatos de edad gestacional menor a 32 semanas. Los resultados contribuyen en la toma de decisiones basadas en pruebas.
