These are the conclusions of a study conducted by University of Granada scientists and the San Cecilio Clinical Hospital (Granada), published in the prestigious journal Pediatrics
Late clamping of the umbilical cord increases the anti-oxidant capacity of mature newborns, and the moderation of inflammatory effects in the case of those born from induced labour
A study conducted by University of Granada scientists (from the Physiology, Obstetrics and Gynaecology Departments) and from the San Cecilio Clinical Hospital (Granada) has demonstrated that delaying the cutting of the umbilical cord in newborns by two minutes leads to a better development of the baby during the first days of life.
This multidisciplinary work, published in the prestigious journal Pediatrics reveals that the time in cutting the umbilical cord (also called umbilical cord clampling) influences the resistance to oxidative stress in newborns.
For this research, scientists worked with a group of 64 healthy pregnant women who went into labour in the San Cecilio Clinical Hospital in Granada. They all had a normal pregnancy and spontaneous vaginal delivery. Half of the newborns had their umbilical cord cut 10 seconds after delivery, whereas the other half had it cut after two minutes.
Beneficial effect
The results of this research suggest that there are beneficial effects in the late clampling of the umbilical cord: there was an increase in the antioxidant capacity of mature newborns and there was moderation of inflammatory effects in the case of induced delivery.
According to the PI in this project, University of Granada professor Julio José Ochoa Herrera, umbilical cord clamping is one of the most frequent surgical interventions practiced upon humans, and we have had proof of such practice for centuries. However, the right timing for clamping is controversial, and it involves important differences both for the mother and for the newborn.
This research led by the University of Granada compares for the first time the impact of the moment of clamping upon the oxidative stress and the inflammatory signal produced during delivery in both the mother and the newborn. “Our study demonstrates that late clamping of the umbilical cord has a beneficial effect upon the antioxidant capacity and reduces the inflammatory signal induced during labour, which could improve the development of the newborn during his or her first days of life”, Ochoa concluded.

74018 According to a new study, delaying umbilical cord cutting by 2 minutes after birth may result in better development in a newborn’s first days of life.
When to cut the umbilical cord has been debated and changed over a long period of time. Before studies began in the mid-1950s, cord clamping within 1 minute of birth was defined as «early clamping,» and «late clamping» was defined as more than 5 minutes after birth. And the American Congress of Obstetricians and Gynecologists (ACOG) have stated, «the ideal timing for umbilical cord clamping has yet to be established.»
To provide further evidence in the debate of early versus late cord clamping, researchers led by Professor Julio José Ochoa Herrera of the University of Granada, assessed newborn outcomes for infants born to 64 healthy pregnant women to determine the impact of clamping timing on oxidative stress and the inflammatory signal produced during delivery.
All of these women had a normal pregnancy and spontaneous vaginal delivery. However, half of the women’s newborns had their umbilical cord cut 10 seconds after delivery and half had it cut after 2 minutes.
Results showed that with late cord clamping there was an increase in antioxidant volume and moderation of inflammatory effects in newborns.
Other studies have shown that delaying clamping allows more time for blood to move from the placenta through the cord, improving iron and hemoglobin levels in newborns.
If delaying cord clamping is beneficial for newborns, then why do many doctors perform a quick cut? Apparently there are several reasons.
According to ACOG, a previous series of studies into blood volume changes after birth concluded that in healthy term infants, more than 90% of blood volume was attained within the first few breaths he or she took after birth.
As a result of these findings, as well as a lack of other recommendations regarding optimal timing, the amount of time between birth and umbilical cord clamping was widely shortened; in most cases, cord clamping occurs within 15-20 seconds after birth.
The World Health Organization (WHO) believes waiting longer is better. WHO supports late cord clamping (1-3 minutes) because it «allows blood flow between the placenta and neonate to continue, which may improve iron status in the infant for up to 6 months after birth.»
ACOG states on their website that «Concerns exist regarding universally adopting delayed umbilical cord clamping. Delay in umbilical cord clamping may jeopardize timely resuscitation efforts, if needed, especially in preterm infants. However, because the placenta continues to perform gas exchange after delivery, sick and preterm infants are likely to benefit most from additional blood volume derived from a delay in umbilical cord clamping.»
WHO states clearly that that early cord clamping – less than 1 minute after birth – is not advised unless the newborn is asphyxiated and needs to be moved for resuscitation.
Simply holding a wet, crying and wiggling baby for 2 minutes may also prove difficult for physicians whose hands are gloved. The better option may be to place the baby on the mother’s stomach, wait the 2 minutes and then cut the cord.
More and more studies are finding that in certain circumstances, waiting a couple of minutes longer to cut the umbilical cord may be best for baby.
According to this study, there’s really no reason why newborns from a normal pregnancy and vaginal delivery should not be allowed at least 2 minutes before the cord is clamped after birth.
Mothers and fathers-to-be should discuss cord cutting timing with their doctor before the baby is born. If your preference is to allow more time before cutting the cord when your baby arrives, let your physician know ahead of time. He or she can then advise you on when early clamping may be necessary and when it can wait a couple of extra minutes.

75057 La naranja puede revivir sus momentos más dulces. Porque según dicen, es más saludable de lo que se tenía en el imaginario colectivo. Y los que lo dicen son investigadores de la Universidad de Granada, que han desarrollado una nueva técnica para medir el nivel de antioxidantes presentes en el zumo de naranja y sus resultados dicen que son diez veces superior en esa faceta de lo que se creía.
Al parecer el jugo con su pulpa es mucho más beneficioso de lo que se suponía, aunque parece que en Valencia haya que ponerse las pilas para concienciar a la gente, al menos eso se desprende después de preguntar a algunos ciudadanos por las calles de la ciudad. No suelo tomar zumo ni fruta o me sienta mal, son algunas de las respuestas con las que nos hemos encontrado.
En cualquier caso, como apunta Vicente Lladró en LAS PROVINCIAS, en el estudio no se concretan diferencias entre zumo natural e industrial, pero si dan importancia a la presencia de la fibra en la pulpa.

C’est ce qui s’ensuit d’une étude réalisée par des scientifiques de l’Université de Grenade et de l’Hôpital Clinique San Cecilio de Grenade, publiée par la prestigieuse revue Pediatrics.
Retarder la coupure du cordon ombilical produit une augmentation de la capacité antioxydante des nouveau-nés à terme et une modération des effets inflammatoires dans le cas des accouchements induits.
Une étude réalisée par des scientifiques de l’Université de Grenade (départements de Physiologie et d’Obstétrique) et l’Hôpital Clinique San Cecilio de Grenade a démontré que retarder de deux minutes la coupure du cordon ombilical produit un meilleur développement du nouveau-né pendant ses premiers jours de vie.
Ce travail multidisciplinaire, publié dans la prestigieuse revue Pediatrics, révèle que le moment de la coupure du cordon ombilical (aussi appelé clampage du cordon) influe sur la résistance au stress oxydant des nouveau-nés.
Dans cette recherche, les scientifiques ont travaillé sur un échantillonnage de 64 femmes saines enceintes ayant accouché à l’Hôpital Clinique San Cecilio de Grenade et toutes eu une grossesse normale et un accouchement spontané vaginal. La coupure du cordon ombilical a été effectuée, chez la moitié des nouveau-nés, dix secondes après la naissance alors que cette opération s’est faite chez l’autre moitié deux minutes après.
Effet bénéfique
Les résultats obtenus suggèrent un effet bénéfique de la coupure tardive du cordon ombilical vu qu’il s’est produit une augmentation de la capacité antioxydante des nouveau-nés à terme et une modération des effets inflammatoires dans le cas des accouchements induits.
Tel que l’explique l’auteur principal de cette étude, le professeur Julio José Ochoa Herrera, de l’Université de Grenade, la coupure du cordon ombilical est une des interventions les plus pratiquées chez les humains, et dont on connaît la pratique depuis des siècles. Cependant, le moment de la coupure ou clampage du cordon ombilical est un sujet controversé qui présente des différences aussi bien pour la mère que pour le nouveau-né.
La recherche dirigée par l’Université de Grenade compare pour la première fois l’influence du moment de la coupure du cordon ombilical dans le stress oxydant et l’effet inflammatoire produit lors de l’accouchement aussi bien pour la mère que pour le nouveau-né. « Notre étude démontre que la coupure tardive du cordon ombilical produit un effet bénéfique pour la capacité oxydative et réduit l’effet inflammatoire induit lors de l’accouchement, ce qui pourrait améliorer le développement postnatal du nouveau-né pendant ses premiers jours de vie », conclut Ochoa.
