Metabolomic profiling in blood from umbilical cords of low birth weight newborns
2012
AbstractBackgroundLow birth weight has been linked to an increased risk to develop obesity, type 2 diabetes, and hypertension in adult life, although the mechanisms underlying the association are not well understood. The objective was to determine whether the metabolomic profile of plasma from umbilical cord differs between low and normal birth weight newborns.MethodsFifty healthy pregnant women and their infants were selected. The eligibility criteria were being born at term and having a normal pregnancy. Pairs were grouped according to their birth weight: low birth weight (LBW, birth weight < 10thpercentile, n = 20) and control (control, birth weight between the 75th-90thpercentiles, n…
Human breast areolae as scent organs: morphological data and possible involvement in maternal-neonatal coadaptation.
2006
In humans, areolar skin glands (AG) enlarge during pregnancy and lactation. Their role in mother-infant interactions may pertain to protective, mechanical, and communicative functions. It was questioned here whether more profuse AG could be related to more optimal adaptation to breastfeeding. A morphological study of the areolae was undertaken between birth and day 3 to assess the number, secretory status, and spatial distribution of AG. These data were related to infants' weight variation, mothers' perception of their infant's behavior at breast, and time between delivery and onset of lactation. AG were seen in virtually all women but with great interindividual variations; their areolar di…
Health literacy and its relation to continuing with breastfeeding at six months post-partum in a sample of Spanish women
2021
Aim To explore the relation between health literacy (HL) and continuing breastfeeding (BF) at 6 months post-partum. Design Observational, longitudinal and prospective study between December 2018–May 2019. The STROBE checklist was used. Methods 114 mother/baby pairings from a Spanish Hospital were included. Mothers’ health literacy was studied with the Newest Vital Sign and Short Assessment of Health Literacy for Spanish Adults 50 (SAHLSA-50). Before hospital discharge, BF efficiency was studied using the LATCH BF score and BF continuity was followed for 6 months. Survival analysis and Cox regression were done. Results Health literacy levels and BF effectiveness were adequate before hospital…
The role of noninvasive brain oximetry in adult critically ill patients without primary non-anoxic brain injury.
2021
A primary objective in intensive care and perioperative settings is to promote an adequate supply and delivery of oxygen to tissues and organs, particularly to the brain. Cerebral near infrared spectroscopy (NIRS) is a noninvasive, continuous monitoring technique, that can be used to assess cerebral oxygenation. Using NIRS to monitor cerebral oximetry is not new and has been in widespread use in neonates and cardiac surgery for decades. In addition, it has become common to see NIRS being used in adult and pediatric cardiac surgery, acute neurological diseases, neurosurgical procedures, vascular surgery, severe trauma and other acute medical diseases. Furthermore, recent evidence suggests a …
Experts' assessment of probability and level of pesticide exposure in agricultural workers.
2000
The occupational history of the parents of 261 infants with congenital malformations and 261 matched controls was collected. During the relevant time period before the birth of their child, 183 parents were involved in agricultural activities, 49% of them having directly applied pesticides. Two experts assessed the probability and the level of exposure to each quoted pesticide (582 observations) by using 4-point scales. Interrater agreement was estimated. Kappa-weighted values for probability and level of exposure were, respectively, kappa = 0.36 and kappa = 0.39. In the analysis of some categories of exposure (non-applicators, herbicides) very low interrater agreement was observed. In epid…
Foetal erythrocytes exhibit an increased ability to scavenge for nitric oxide
1998
The presence of adult human whole blood inhibited in vitro relaxations of rat aortic rings by the nitric oxide (NO) donor S-nitroso-N-acetyl-DL-penicillamine (SNAP). Incubation with foetal blood containing the same concentration of haemoglobin produced a shift to the right of the relaxation curve. SNAP-induced vasorelaxations were more inhibited by dialysed solutions of haemoglobin than by the presence of erythrocytes in the organ bath, but there were no differences between the effect of adult or foetal haemoglobins. The presence of plasma from adult or foetal blood did not modify the effects of SNAP. Relaxations induced by endogenous, endothelium-derived, NO were more inhibited by foetal t…
Bile salt-stimulated lipase activity in human colostrum from mothers of infants of different gestational age and birthweight.
1987
. The bile salt-stimulated lipase (BSSL) activity was measured in milk collected at 3–4 days postpartum (colostrum) from 36 mothers divided into three groups according to gestational age and birthweight of their infants. BSSL activity changed with the length of gestation. Preterm colostrum presented a mean activity significantly higher than the term groups (small-for-gestational age and appropriate-for-gestational age) which had similar values. The ratio of BSSL activity to the estimated fat content was 6.33 in colostrum of mothers who delivered preterm and 4.20 in colostrum of both groups of term mothers. These data suggest that preterm colostrum has a higher fat digesting potential than t…

Prenatal Exposure to Polybrominated Flame Retardants and Fetal Growth in the INMA Cohort (Spain)
2015
Our aim was to investigate the relation between PBDEs and fetal growth or newborn anthropometry in a Spanish cohort (2003-2008). PBDE congeners (BDE-47, -99, -153, -154, and -209) were determined in serum of 670 mothers at gestational week 12 and in 534 umbilical cord samples. Abdominal circumference (AC), estimated fetal weight (EFW), femur length (FL), and biparietal diameter (BPD) during gestation were measured by ultrasounds. At birth, weight (BW), head circumference (HC), and length (BL) were also measured. We assessed growth in the intervals between 12-20 and 20-34 weeks of gestation and size at birth by standard deviation (SD)-scores adjusted for constitutional characteristics. We co…
Obstetric significance of anti-Jr(a) antibody.
2001
Abstract The first case in the English-language medical literature of anti-Jr a antibody during pregnancy in a Spanish woman is described. The few reported cases to date about this issue are reviewed, with advice as to an obstetric guideline to follow for pregnant women with this antibody. (Am J Obstet Gynecol 2001;184:75-6.)
