RESUMO

Introducción: En la actualidad, las alteraciones del neurodesarrollo son la complicación más frecuente en los pacientes con cardiopatía congénita (CC) en edad escolar. Analizamos la incidencia de eventos neurológicos agudos (ENA) en pacientes con CC sometidos a cirugía cardiaca y la utilidad de los neuromarcadores para predecir el neurodesarrollo. Métodos: Estudio prospectivo observacional en recién nacidos (RN) con CC diagnosticada prenatalmente, y sometidos a cirugía el primer año de vida. Se evaluaron: 1) biomarcadores sanguíneos de lesión cerebral (S100B, enolasa neuronal específica) en sangre de cordón y periquirúrgicos; 2) datos clínicos y analíticos perinatales y periquirúrgicos; 3) tratamientos y complicaciones, y 4) neurodesarrollo (escala de Bayley III) a los 2 años. Resultados: Se incluyeron 84 RN con CC de diagnóstico fetal, confirmada posnatalmente, sometidos a cirugía cardiaca en el primer año de vida. Diecisiete pacientes tenían corazón univentricular, 20 pacientes obstrucción izquierda y 10 síndromes genéticos. Fallecieron en el periodo posquirúrgico 5 pacientes (5,9%) y 9 pacientes presentaron ENA (10,7%). Las puntuaciones medias en el test de Bayley III fueron normales, pero el 31% tuvieron alteración cognitiva, motora o en el lenguaje. Los pacientes con síndromes genéticos, ENA y CC univentriculares tuvieron peor neurodesarrollo. La elevación de S100B en el postoperatorio inmediato se correlacionó con peores puntuaciones. Conclusiones: Los pacientes con CC sometidos a cirugía tienen mayor riesgo de sufrir alteraciones del neurodesarrollo. Los pacientes con síndromes genéticos o corazones univentriculares presentan peores resultados. Presentar ENA posquirúrgico puede contribuir a peores resultados. Niveles de S100B elevados en el postoperatorio se correlacionan con peores resultados en los test de neurodesarrollo a los 2 años...(AU)


Introduction: At present, neurodevelopmental abnormalities are the most frequent type of complication in school-aged children with congenital heart disease (CHD). We analysed the incidence of acute neurologic events (ANEs) in patients with operated CHD and the usefulness of neuromarkers for the prediction of neurodevelopment outcomes. Methods: Prospective observational study in infants with a prenatal diagnosis of CHD who underwent cardiac surgery in the first year of life. We assessed the following variables: (1) serum biomarkers of brain injury (S100B, neuron-specific enolase) in cord blood and preoperative blood samples; (2) clinical and laboratory data from the immediate postnatal and perioperative periods; (3) treatments and complications; (4) neurodevelopment (Bayley-III scale) at age 2 years. Results: The study included 84 infants with a prenatal diagnosis of CHD who underwent cardiac surgery in the first year of life. Seventeen had univentricular heart, 20 left ventricular outflow obstruction and 10 genetic syndromes. The postoperative mortality was 5.9% (5/84) and 10.7% (9/84) patients experienced ANEs. The mean overall Bayley-III scores were within the normal range, but 31% of patients had abnormal scores in the cognitive, motor or language domains. Patients with genetic syndromes, ANEs and univentricular heart had poorer neurodevelopmental outcomes. Elevation of S100B in the immediate postoperative period was associated with poorer scores. Conclusions: Children with a history of cardiac surgery for CHD in the first year of life are at risk of adverse neurodevelopmental outcomes. Patients with genetic syndromes, ANEs or univentricular heart had poorer outcomes. Postoperative ANEs may contribute to poorer outcomes. Elevation of S100B levels in the postoperative period was associated with poorer neurodevelopmental outcomes at 2 years...(AU)

Elevation of S100B levels in the postoperative period was associated with poorer neurodevelopmental outcomes at 2 years. Studies with larger samples and longer follow-ups are needed to define the role of these biomarkers of brain injury in the prediction of neurodevelopmental outcomes in patients who undergo surgery for management of CHD.

RESUMO

N-terminal pro-brain natriuretic peptide (NT-proBNP) and uric acid are elevated in pregnancies with preeclampsia (PE). Short-term prediction of PE using angiogenic factors has many false-positive results. Our objective was to validate a machine-learning model (MLM) to predict PE in patients with clinical suspicion, and evaluate if the model performed better than the sFlt-1/PlGF ratio alone. A multicentric cohort study of pregnancies with suspected PE between 24+0 and 36+6 weeks was used. The MLM included six predictors: gestational age, chronic hypertension, sFlt-1, PlGF, NT-proBNP, and uric acid. A total of 936 serum samples from 597 women were included. The PPV of the MLM for PE following 6 weeks was 83.1% (95% CI 78.5−88.2) compared to 72.8% (95% CI 67.4−78.4) for the sFlt-1/PlGF ratio. The specificity of the model was better; 94.9% vs. 91%, respectively. The AUC was significantly improved compared to the ratio alone [0.941 (95% CI 0.926−0.956) vs. 0.901 (95% CI 0.880−0.921), p < 0.05]. For prediction of preterm PE within 1 week, the AUC of the MLM was 0.954 (95% CI 0.937−0.968); significantly greater than the ratio alone [0.914 (95% CI 0.890−0.934), p < 0.01]. To conclude, an MLM combining the sFlt-1/PlGF ratio, NT-proBNP, and uric acid performs better to predict preterm PE compared to the sFlt-1/PlGF ratio alone, potentially increasing clinical precision.

RESUMO

BACKGROUND: Cardiovascular diseases (CVD) are cause of increased morbidity and mortality in spite of advances for diagnosis and treatment. Changes during pregnancy affect importantly the maternal CV system. Pregnant women that develop preeclampsia (PE) have higher risk (up to 4 times) of clinical CVD in the short- and long-term. Predominance of an anti-angiogenic environment during pregnancy is known as main cause of PE, but its relationship with CV complications is still under research. We hypothesize that angiogenic factors are associated to maternal cardiac dysfunction/remodeling and that these may be detected by new cardiac biomarkers and maternal echocardiography. METHODS: Prospective cohort study of pregnant women with high-risk of PE in first trimester screening, established diagnosis of PE during gestation, and healthy pregnant women (total intended sample size n = 440). Placental biochemical and biophysical cardiovascular markers will be assessed in the first and third trimesters of pregnancy, along with maternal echocardiographic parameters. Fetal cardiac function at third trimester of pregnancy will be also evaluated and correlated with maternal variables. Maternal cardiac function assessment will be determined 12 months after delivery, and correlation with CV and PE risk variables obtained during pregnancy will be evaluated. DISCUSSION: The study will contribute to characterize the relationship between anti-angiogenic environment and maternal CV dysfunction/remodeling, during and after pregnancy, as well as its impact on future CVD risk in patients with PE. The ultimate goal is to improve CV health of women with high-risk or previous PE, and thus, reduce the burden of the disease. TRIAL REGISTRATION: NCT04162236.

RESUMO

Preeclampsia is caused by placental impairment with increased expression of sFlt-1 (soluble fms-like tyrosine kinase 1) and decreased PlGF (placental growth factor); it has been associated with cardiovascular morbidity and mortality later in life, but the underlying mechanism remains unknown. The aim of this study was to determine whether sFlt-1 and PlGF levels during preeclampsia are associated to long-term cardiovascular risk. We prospectively recruited 43 women with previous preeclampsia and 21 controls with uncomplicated pregnancies. Cardiovascular risk assessment ≈12 years later included maternal hemodynamic, cardiac function and structure, biomarker analysis, and carotid-intima thickness evaluation. Women with previous preeclampsia had higher prevalence of hypertensive disorders and dyslipidemia than controls. In addition, they had worse global longitudinal strain, thicker left ventricular septal and posterior walls, more myocardial mass and increased carotid intima-media thickness compared with controls. PlGF during pregnancy correlated positively with high-density lipoprotein (r=0.341; P=0.006), and negatively with global longitudinal strain (r=-0.581; P<0.001), carotid intima-media thickness (r=-0.251; P=0.045), and mean arterial blood pressure (r=-0.252; P=0.045), when adjusted by study group. sFlt correlated negatively with high-density lipoprotein (r=-0.372; P=0.002) and apolipoprotein A-1 (r=-0.257; P=0.040), and positively with carotid intima-media thickness (r=0.269; P=0.032) and left ventricular posterior wall thickness (r=0.368; P=0.003). The antiangiogenic state present in preeclampsia is related to greater prevalence of cardiovascular risk factors ≈12 years after delivery. The knowledge of altered angiogenic factors may help detect women with a higher risk for premature cardiovascular disease, who will require earlier follow-up after delivery.

RESUMO

INTRODUCCIÓN: La restricción del crecimiento intrauterino (RCIU) y la prematuridad se han asociado con una mayor morbimortalidad perinatal, así como con una reprogramación fetal a nivel cardiovascular. Sin embargo, son escasos los estudios sobre el impacto de la RCIU de causa placentaria en los resultados perinatales y en biomarcadores cardiovasculares de recién nacidos prematuros. OBJETIVOS: Determinar las diferencias en morbimortalidad neonatal y biomarcadores de disfunción cardiovascular en sangre de cordón entre prematuros con RCIU de origen placentario y sin RCIU, así como estudiar su relación con la gravedad de la RCIU según el estudio Doppler fetal. MATERIAL Y MÉTODOS: Estudio prospectivo de cohortes: prematuros con RCIU de causa placentaria y prematuros sin RCIU adecuadamente apareados. Clasificación de la gravedad de la RCIU según el Doppler. Análisis comparativo de resultados perinatales, de morbimortalidad neonatal y de niveles en sangre de cordón de biomarcadores de disfunción cardiovascular. RESULTADOS: Los prematuros con RCIU presentan un menor peso, longitud, perímetro craneal y Apgar al nacimiento, así como un aumento de la morbilidad neonatal y de los niveles de biomarcadores de disfunción cardiovascular, comparado con los prematuros sin RCIU. Estas diferencias aumentan con la gravedad de la RCIU determinada por el estudio hemodinámico Doppler prenatal. CONCLUSIONES: Los prematuros afectados de RCIU de causa placentaria presentan un incremento de la morbimortalidad neonatal independiente de la prematuridad, que aumenta de forma estadísticamente significativa con la gravedad de la RCIU. La afectación placentaria y su gravedad también determinan la alteración de biomarcadores de disfunción cardiovascular al nacimiento


INTRODUCTION: Intrauterine growth restriction (IUGR) and prematurity have been associated with increased perinatal morbidity and mortality and also with cardiovascular foetal programming. However, there are few studies on the impact of placenta-related IUGR on perinatal outcomes and cardiovascular biomarkers in pre-term infants. OBJECTIVES: To determine differences in neonatal morbidity, mortality and cord blood biomarkers of cardiovascular dysfunction between pre-term placenta-related IUGR and non-IUGR new-borns, and to analyse their relationship with the severity of IUGR according to foetal Doppler evaluation. MATERIAL AND METHODS: Prospective cohort study: pre-term infants with placenta-related IUGR and matched pre-term infants without IUGR. A Doppler scan was performed, and placenta- IUGR was classified according to severity. Comparative analysis of perinatal outcomes, neonatal morbidity and mortality, and cord blood levels of biomarkers of cardiovascular dysfunction was performed. RESULTS: IUGR new-borns present lower weight, length, head circumference, and Apgar score at birth, as well as increased neonatal and cardiovascular dysfunction biomarker levels, compared with pre-term new-borns without IUGR. These differences increase with the severity of IUGR determined by prenatal umbilical artery Doppler scan. CONCLUSIONS: Placenta-related-IUGR pre-term infants, irrespective of gestational age, present increased neonatal morbidity and mortality that is significantly proportional to the severity of IUGR. Placental impairment and severity also determine levels of cardiovascular dysfunction biomarkers at birth

RESUMO

OBJECTIVE: Intrauterine-growth restriction is associated with impaired neurodevelopment. However, studies on early childhood neurodevelopment of premature infants with placenta-related intrauterine-growth restriction (IUGR) are scarce and heterogeneous. We aimed to analyze the impact of placenta-related IUGR on preschool age neurodevelopment in preterm infants, and to ascertain which prenatal and postnatal factors influence neurodevelopment in these infants. METHODS: Prospective cohorts study: 48 placenta-related IUGR premature infants and 25 matched non-IUGR premature infants (mean gestational age: 31.4 and 31.6 weeks, respectively). Preschool neurodevelopment assessment with cognitive Bayley Scales III and with ASQ-III surveys (age interval: 34.07-42.50 months). Inter-cohort result comparison. Analysis of perinatal and environmental factors associated with impaired neurodevelopment in both cohorts. RESULTS: No statistically significant neurodevelopment differences were observed at preschool age between both preterm cohorts. Multivariate analysis of perinatal and environmental factors showed daycare, breastfeeding, higher parental educational level, and absence of severe neonatal morbidity to be associated with a lower risk of altered neurodevelopment at preschool age. CONCLUSIONS: Placenta-related IUGR does not have a significant impact on preschool neurodevelopment in our preterm patients. Instead, post-natal positive environmental factors such as parental educational level, breastfeeding, and daycare attendance make a difference towards an improvement in neurodevelopment in these infants.

RESUMO

Se presentan dos pacientes que no mostraban enfermedades sistémicas que pudieran afectar el proceso normal de crecimiento y desarrollo; sin embargo, en las radiografías simples de cráneo se constató el cierre prematuro de la sutura sagital media en el primer caso y de la coronal en el segundo, por lo que se decidió aplicar las medidas propuestas en el cefalograma craneofacial para niños de tres a 11 meses de edad con patrón de crecimiento y desarrollo normal. A partir de las radiografías tomadas se les realizó la predicción quirúrgica cefalométrica previa a la intervención quirúrgica y luego se corroboró, a los 15 días y a los tres meses de operados, si el crecimiento y el desarrollo craneofacial se correspondían con los intervalos de medidas propuestas en el cefalograma craneofacial para niños sin deformidades craneales con el objetivo de redirigir el crecimiento craneofacial y evitar displasias esqueléticas de los maxilares desde edades tempranas en los niños con estas deformidades craneales. Entre las medidas propuestas en el cefalograma para lograr la armonía en el crecimiento y el desarrollo craneofacial se encuentran el índice de Retzius, la longitud anteroposterior de la base del cráneo, la convexidad frontal respecto a los puntos F1, F2 y F3, la referencia del tercio medio facial y el ancho biparietal, bicigomático y maxilar. Aparecen fotos que permiten mostrar su evolución satisfactoria

RESUMO

El traumatismo en la dentición temporal, como causa de alteración del diente permanente en desarrollo, está ampliamente demostrado por la experiencia clínica e investigadora; existen pocas publicaciones acerca de qué factores más frecuentemente se asocian a la presencia de daños, como secuelas de un trauma en el predecesor temporal. En esta investigación, se determinaron los factores asociados a la presencia de complicaciones como consecuencia de un traumatismo en la dentición temporal, y para ello se realizó un estudio descriptivo retrospectivo entre los meses de enero de 2009 hasta febrero de 2010 en las escuelas primarias del área norte del municipio de Placetas, que estuvo integrado por 83 niños. La información se obtuvo mediante entrevistas y encuestas de conocimientos y fue procesada utilizando métodos de la estadística descriptiva diferencial. Se obtuvo como resultado que las edades tempranas en que sucedió el daño, el tipo de tratamiento, el nivel de información de los padres y el dominio sobre el tema que poseen los estomatólogos, fueron los factores asociados(AU)
