Le nouveau-né prématuré : un modèle pour l'étude du développement du comportement alimentaire
2008
La naissance prematuree est exemplaire pour comprendre les evenements les plus precoces de la formation des comportements alimentaires. La succession des modes d’alimentation pour subvenir aux besoins nutritifs de l’enfant (alimentation continue ou discontinue ; passive par sonde ou active au sein/biberon ; lait humain ou artificiel ; alimentation par mere ou soignants) ponctue en effet les etapes de la coordination succion-deglutition-respiration et sa capacite a reguler ces evenements. Le contexte particulier des prises alimentaires, peu propice a l’exposition a la variete sensorielle (en particulier chimiosensorielle), croise avec les singularites des pratiques parentales, compose la tra…

First-year blood pressure increase steepest in low birthweight newborns.
2006
The present research has been undertaken prospectively to study the impact of birthweight and growth pattern on blood pressure changes from birth through the first year of life.Parents of newborns born at term (gestational age37 weeks) after uncomplicated pregnancies and in the absence of perinatal illness were randomly invited to allow their children to participate in the study. One hundred and forty-nine (84 male and 65 female) newborns were included in the present analysis. The newborns were divided into four groups according to birthweight:2500 g (n = 23); 2500-2999 g (n = 39); 3000-3500 g (n = 48); and3500 g (n = 39).At birth systolic and diastolic blood pressure were significantly low…
Cry characteristics of 172 healthy 1-to 7-day-old infants.
2002
A total of 1,836 cry signals from 172 healthy babies, 1–7 days old, were analysed with sound spectrography. The mean values for the 8–15 cries from each infant were calculated and used for the statistical analyses. The mean duration of the cry signals was 1.4 ± 0.6 s. The mean fundamental frequency was 496 ± 95 cps (Hz). Fifty percent of the mean fundamental frequencies in the 8–15 cries analysed from each baby varied between 450 and 520 Hz. Of the children, 93% had cries with a mean fundamental frequency below 600 Hz. The mean value of the highest point of the fundamental frequency was 583 ± 151 Hz and of the lowest point 398 ± 75 Hz. The melody type had mainly a rising-falling contour, th…
ANALYSIS OF WHOLE BLOOD AND PLACENTA—A CASE STUDY OF MOTHERS AND THEIR BABIES
2002
In a previous report optimisation of ED-XRF and TXRF for whole blood analysis has been reported. In the present work the optimised technique has been applied to investigate possible influence on pregnancy outcome due to an environment characterised by high levels of pollutants. Two groups of maternal and neonate whole blood were analysed with TXRF and GFAAS. The material of the first group was taken from Zabrze (Upper Silesia, Poland), an industrial region with a high degree of pollution. The second group consisted of controls from the Goteborg region in Sweden, where the levels of toxic pollutants in the environment are not as high as those in Zabrze. The results show that as compared with…
D-dímeros en el recién nacido sano
2015
El sistema de coagulación neonatal es un sistema dinámico con valores de proteínas hemostáticas que cambian sobretodo en las primeras semanas y meses de vida para alcanzar valores de adulto alrededor de los seis meses de vida postnatal para la mayoría de ellas. En neonatos, la elevación de los D-dímeros se consideran como el biomarcador más sensible de la fibrinolisis secundaria a la activación previa de la coagulación ante la existencia de un trombo. Estudios en población adulta y niños mayores de un año han demostrado su aplicabilidad práctica debido a su elevada sensibilidad y valor predictivo negativo. Existen pocos estudios publicados de valores de D-dímeros en recién nacidos sanos. Hi…
Valores de referencia de saturación de oxígeno y frecuencia cardíaca en recién nacidos por parto vaginal con pinzamiento tardío del cordón umbilical …
2022
La transición fetal neonatal es una etapa de importantes cambios fisiológicos. La reciente incorporación del pinzamiento tardío de cordón umbilical (PTC) y el contacto piel con piel (CPP) como rutinas de cuidado en las unidades obstétricas justifica el objetivo principal de esta tesis. Este fue determinar los valores de referencia de saturación de oxígeno (SpO2) y frecuencia cardíaca (FC) mediante el uso de pulsioximetría (PO) en neonatos a término durante los primeros 10 minutos de vida, con la realización de pinzamiento tardío del cordón umbilical (PTC) durante ≥60 segundos y contacto piel con piel (CPP) inmediato desde el nacimiento. Para alcanzar los objetivos se registraron a través de…
Distribution of lymphocyte surface antigens in healthy neonates.
1994
Using flow cytometric analysis we investigated the distribution of major lymphocyte surface antigens in newborn infants. A total of 221 newborns entered the study, of whom 53 fullfilled our criteria of healthy mature neonates. Percentages of immunofluorescent-positive cells were as follows (median and range from 25th to 75th percentiles given): for CD1 3.8%; 2.3%–5.8%. CD2 60.9%; 52.4%–66.8%. CD3 57.5%; 50.5%–63.3%. TcRas 57.7%; 48.1%–60.0%. CD4 36.3%; 28.0%–42.6%. CD8 23.0%; 20.0%–27.4%. CD11a 56.3%; 46.3%–68.5%. CD19 12.1%; 8.6%–14.8%. CD20 10.9%; 8.4%–12.9%. CD25 2.6%; 2.1%–4.5%. CDw52 61.0%; 51.2%–76.1%. CD71 5.2%; 3.1%–9.3%. While the ranges for the percentage of immunofluorescent-posi…

Sonographische Darstellbarkeit und Größenbestimmung von Abdominalorganen bei gesunden Neugeborenen
1988
The determination of organ size is another important criterium in ultrasound examination. There are only few investigations in the neonatal group. Therefore in a prospective study the abdominal organs of 85 neonates were examined with a 7.5 MHz small part scanner. These organs were measured in standardized sections in order to establish normal values]
