Necrotising enterocolitis is an infection which attacks and kills the lining of the bowel and affects mainly premature infants.
Dr Sanjay Patole, King Edward Memorial Hospital for Women, Perth, Western Australia, Australia, and colleagues studied the results of seven trials involving babies born at 33 weeks or earlier and less than 1.5kg in body weight.
In a meta-analysis (a study which combines the results of previous trials) the researchers found the risk of contacting necrotising enterocolitis was reduced by 64% and the risk of death reduced by 53% in groups of premature babies given probiotics compared to the control groups. The risk of sepsis occurring in babies was not significantly different between the groups given probiotics and the control groups.
And the time taken for the premature babies to achieve full feeds was less when they were given probiotic supplements, by an average of nearly three days.
The authors say: “The remarkably consistent results, despite the distinct differences in dose, timing, and types of organism used, suggest that substantial latitude might be available in the choice of an effective probiotic regimen in the design of further trials.”
They conclude: “If a large, well designed-trial confirms our results, it could make a very strong case for the routine use of probiotics in preterm neonates.”
In an accompanying comment, Dr Carlo Caffarelli, Paediatric Clinic, University of Parma, Italy, said: “The usual measures for the prevention of necrotising enterocolitis are feeding with human milk and delaying preterm delivery. The overview by Patole and colleagues is an important step towards an evidence-based use of probiotics.
“However, further large trials are needed before recommending these promising agents.”

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
