Uterine artery Doppler at 11–14 weeks of gestation to screen for hypertensive disorders and associated complications in an unselected population

To establish reference values for the first‐trimester uterine artery (UtA) pulsatility index (PI) and to investigate the role of UtA Doppler in the early prediction of hypertensive disorders and their associated complications in an unselected Mediterranean population.

Sequential changes in uterine artery blood flow pattern between the first and second trimesters of gestation in relation to pregnancy outcome.

To describe sequential changes in uterine artery waveform between the first and second trimesters of gestation and to analyze their association with the subsequent risk of hypertensive disorders and fetal growth restriction (IUGR).

Doppler assessment of the aortic isthmus and perinatal outcome in preterm fetuses with severe intrauterine growth restriction

To evaluate the characteristics and association with perinatal outcome of the aortic isthmus (AoI) circulation as assessed by Doppler imaging in preterm growth‐restricted fetuses with placental insufficiency.

Monitoring of fetuses with intrauterine growth restriction : longitudinal changes in ductus venosus and aortic isthmus flow

To explore in growth‐restricted fetuses the sequence of changes in aortic isthmus and ductus venosus blood flow in relation to other arterial Doppler parameters commonly used to evaluate fetal wellbeing.

Prenatal diagnosis and outcome for fetuses with congenital absence of the pulmonary valve.

To analyze fetal echocardiographic findings of absent pulmonary valve syndrome (APVS), its association with chromosomal and extracardiac anomalies including nuchal translucency (NT) and the outcome after diagnosis.

Reference ranges for Doppler parameters of the fetal aortic isthmus during the second half of pregnancy

To establish reference ranges for blood flow velocity waveforms (FVW) of the fetal aortic isthmus (AoI) during the second and third trimesters of pregnancy.

Doppler assessment of fetal aortic isthmus blood flow in two different sonographic planes during the second half of gestation.

To compare the reliability of Doppler blood flow measurements of the fetal aortic isthmus (AoI) according to whether the sampling plane is obtained from the traditional longitudinal aortic arch (LAA) view or the more recently described three vessels and trachea (3VT) view of the fetal upper mediastinum.

Feasibility and accuracy of fetal echocardiography using four‐dimensional spatiotemporal image correlation technology before 16 weeks' gestation

To evaluate the potential value of early fetal echocardiography (EFE) by means of four‐dimensional (4D) spatiotemporal image correlation (STIC) technology for either reassurance of normality or prenatal diagnosis of major congenital heart defects (CHDs).

Prenatal diagnosis of a right ventricular diverticulum complicated by pericardial effusion in the first trimester

A ventricular diverticulum associated with a large pericardial effusion was diagnosed at 13 weeks of gestation. The pericardial effusion resolved spontaneously by 20 weeks and the diverticular size remained the same during pregnancy. In the postnatal period the neonate underwent surgical correction of both the diverticulum and associated ventricular and atrial septal defects. Our case indicates that congenital ventricular diverticulum may be associated with a good perinatal outcome. Copyright

Consideraciones sobre el uso de los procedimientos naturalistas para la intervención en logopedia

Resumen En el presente trabajo se exponen algunas ideas sobre la aplicacion de los procedimientos naturalistas en logopedia. Despues de una breve presentacion de los fundamentos de este tipo de intervencion, en el articulo se comentan las ventajas e inconvenientes de su uso, comparandolos con los procedimientos tradicionales. Tambien se alerta sobre algunos usos erroneos y sus posibles causas sobre acabar con la aportacion de sugerencias sobre la formacion de logopedas que deseen emplear la intervencion naturalista con profesionalidad.
