Waiting 30 seconds to two minutes after birth to cut the umbilical cord of a premature baby appears to lessen chances of bleeding in the newborn’s brain and reduce the need for transfusions, according to a new review of research.
Standard practice for preterm babies is to cut the cord as soon as possible, often within 10 to 15 seconds. A systematic review finds that delaying the clamping rather than doing it immediately also reduces anemia and increases blood pressure and blood volume, helping preterm infants off to a healthier start in life, says lead study author Heike Rabe, M.D., Ph.D. of Brighton and Sussex University Hospitals in Brighton, England. "If the cord is left unclamped for a short time after the birth, some of the baby’s blood from the placenta passes to the baby to help the flow of blood to the baby’s lungs," Rabe explains. "Delaying cord clamping for just a very short time helped the babies to adjust to their new surroundings better."
The review appears in the October issue of the Cochrane Collaboration, an international organization that evaluates medical research. Systematic reviews draw evidence-based conclusions about medical practice after considering both the content and quality of existing medical trials on a topic.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
