A number of studies in the West have shown that heavy bleeding following childbirth has become more common in recent years. In her thesis, midwife and researcher Elisabeth Jangsten decided to look at how heavily women bleed after giving birth in Angola and Sweden following active and expectant management.
The study in Angola covered 1,590 women, while the Swedish study included 1,802. The Swedish study was conducted at two of the delivery units at Sahlgrenska University Hospital, which make use of both active and expectant management.Active management means that the umbilical cord is clamped straight after the baby is delivered, the midwife gives the mother medication to stimulate uterine contractions, presses a hand on the lower part of the uterus, and pulls gently on the umbilical cord while the mother pushes, so delivering the placenta. With an expectant approach, the umbilical cord is also clamped straight after the baby is delivered, but the midwife then waits for signals that the placenta has separated from the wall of the uterus before encouraging the mother to bear down and push out the placenta. Uterine stimulants are always given if the need arises.
“In Angola, 7.5% of women lost more than a litre of blood in the expectantly managed group, and only 1% in the actively managed group,” says Jangsten, a midwife at Sahlgrenska University Hospital/Östra Hospital and researcher at the Institute of Health and Care Sciences at the Sahlgrenska Academy. “In Sweden, the difference was bigger: almost 17% of women lost more than a litre in the expectantly managed group, and only 10% in the actively managed group.”The researchers did not find any difference between the two methods in terms of perceived afterpains in either Sweden or Angola. However, afterpains were more common the more children the women had had. They also found that first-time mothers in Sweden lost more blood and were more likely to require a blood transfusion than those who had given birth before. More women bled heavily in the Swedish study, which can be explained partly by all blood being measured carefully during the course of the study, but may also be down to other factors, such as excess weight, big babies and greater intervention during childbirth.
The recommendation in Sweden has been to give mothers uterine stimulants immediately after delivery.
“In the light of our results in this thesis, I think that active management should be the first choice for hospital deliveries. However, women should be informed about the different methods available so that they can be involved in decisions about the management of the third stage of labour if they so wish.”POSTPARTUM HAEMORRHAGE

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.
According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
