(Press-News.org) While the health benefits of breast feeding baby are well known, a new study published in BioMed Central's open access journal BMC Pediatrics finds that, for very low birth weight (VLBW) babies, a small amount of fortification can improve growth rates without sacrificing the benefits associated with mother's milk.
Human milk provides babies with exactly the right nutrients for growth and also helps protect against infections and diseases. Breast fed babies are less likely to have diarrhea or vomiting, they have fewer chest and ear infections, and long term are less likely to become obese or develop eczema. However, in hospitals human milk is also associated with slower growth in the first few months of life compared to formula-fed infants.
Researchers from the University of Iowa looked at records of births between 2003 and 2005 in order to compare birth weights, diet, and weight when the baby was discharged from hospital. The majority of VLBW infants (less than 1250g), although small, were the appropriate size for their gestational age (an average of 27 weeks), and stayed in hospital for two to three months after birth. Babies were fed either mother's milk, donor (pasteurized human) milk, or formula, all of which were supplemented as required to improve protein levels and total calories.
The results showed that, while the growth of all the babies was within normal limits, the babies fed more than 75% human milk grew more slowly than babies fed with less than 75% human milk. This difference in growth was even more pronounced for babies fed on donor, rather than mother's, milk.
Dr Tarah Colaizy, who led this study, explained, "Human milk offers many benefits for VLBW infants, and should of course be the default diet for all such infants. However our babies on average became smaller for gestational age between birth and discharge from hospital. We recommend that special attention is given to ensure that the amount protein and calories consumed is necessary to provide the benefits of a human milk diet without sacrificing growth."
So, while breast milk is definitely still best, very small babies may need a little help.

Treatment for cervical disease is not linked to increased risk of preterm births
2012-08-17
Treatment for cervical disease does not appear to increase the risk of subsequently giving birth prematurely, according to a study of over 44,000 women in England. The study, published online in the British Medical Journal [1] today (Friday), is the largest in the UK to investigate this and contradicts previous research suggesting treatment could be linked to an increased risk.
Professor Peter Sasieni, professor of cancer epidemiology and biostatistics at the Wolfson Institute of Preventive Medicine, part of Queen Mary, University of London (UK), led the study. "This ...
Soft robots, in color
2012-08-17
A team of researchers led by George Whitesides, the Woodford L. and Ann A. Flowers University Professor, has already broken new engineering ground with the development of soft, silicone-based robots inspired by creatures like starfish and squid.
Now, they're working to give those robots the ability to disguise themselves.
As demonstrated in an August 16 paper published in Science, researchers have developed a system – again, inspired by nature – that allows the soft robots to either camouflage themselves against a background, or to make bold color displays. Such a ...
Report card shows Australia's oceans are changing
2012-08-17
The 2012 Marine Climate Change in Australia Report Card shows climate change is having significant impacts on Australia's marine ecosystems.
The report card provides information about the current and predicted-future state of Australia's marine climate and its impact on our marine biodiversity. The report card also outlines actions that are underway to help our marine ecosystems adapt to climate change.
"Australia has some of the world's most unique marine ecosystems," project leader CSIRO's Dr Elvira Poloczanska said.
"They are enjoyed recreationally, generate considerable ...
Earthworms soak up heavy metal
2012-08-17
Earthworms could be used to extract toxic heavy metals, including cadmium and lead, from solid waste from domestic refuse collection and waste from vegetable and flower markets, according to researchers writing in the International Journal of Environment and Waste Management.
Swati Pattnaik and M. Vikram Reddy of the Department of Ecology and Environmental Sciences, at Pondicherry University, in Puducherry, India, explain how three species of earthworm, Eudrilus eugeniae, Eisenia fetida and Perionyx excavates can be used to assist in the composting of urban waste and ...
Evolutionary increase in size of the human brain explained
2012-08-17
Researchers have found what they believe is the key to understanding why the human brain is larger and more complex than that of other animals.
The human brain, with its unequaled cognitive capacity, evolved rapidly and dramatically.
"We wanted to know why," says James Sikela, PhD, who headed the international research team that included researchers from the University of Colorado School of Medicine, Baylor College of Medicine and the National Institutes of Mental Health. "The size and cognitive capacity of the human brain sets us apart. But how did that happen?"
"This ...
Use of retail medical clinics continues to grow, study finds
2012-08-17
Fast-growing retail medical clinics are attracting more older patients and delivering more preventive care, particularly flu shots and other vaccinations, according to a new study from the RAND Corporation.
Researchers found that visits to retail medical clinics increased four-fold from 2007 to 2009, with the proportion of patients over age 65 growing from 8 percent to 19 percent of all visits during this period.
More than 44 percent of visits to the clinics occurred on the weekend or other hours when physician offices typically are closed, suggesting retail clinics ...
Will the real independents please stand up?
2012-08-17
As November draws near, many Americans are thinking about which political candidates will be receiving their support. For die-hard Democrats and Republicans, the decision may be a no-brainer. As the country grows increasingly divided between liberals and conservatives, however, many voters have rejected traditional partisan identities, choosing to call themselves Independents.
But new research suggests that Independents may not be as independent as they think.
Psychological scientists Carlee Beth Hawkins and Brian Nosek of the University of Virginia decided to use a ...
Molecular and protein markers discovered for liver transplant failure from hepatitis C
2012-08-17
Researchers have discovered molecular and protein signatures that predict rapid onset of liver damage in hepatitis C patients following a liver transplant. The markers appeared soon after transplant and well before clinical evidence of liver damage.
Such early detection of susceptibility to hepatitis C virus-induced liver injury could lead to more personalized monitoring and treatment options after a transplant. Also, because the markers stem from an underlying pathology occurring at a very basic level, they might reveal why hepatitis C is so clinically variable, and ...
Combination peptide therapies might offer more effective, less toxic cancer treatment
2012-08-17
COLUMBUS, Ohio – Two studies suggest that two peptide agents used either together or individually with a low-dose of a standard chemotherapy drug might offer more effective cancer therapy than current standard single-drug treatments.
The studies used animal models of breast cancer to show that the peptide combinations dramatically delay tumor onset and progression by both inhibiting tumor growth and blocking the formation of new tumor blood vessels, say the researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard ...
Common parasite may trigger suicide attempts
2012-08-17
EAST LANSING, Mich. — A parasite thought to be harmless and found in many people may actually be causing subtle changes in the brain, leading to suicide attempts.
New research appearing in the August issue of The Journal of Clinical Psychiatry adds to the growing work linking an infection caused by the Toxoplasma gondii parasite to suicide attempts. Michigan State University's Lena Brundin was one of the lead researchers on the team.
About 10-20 percent of people in the United States have Toxoplasma gondii, or T. gondii, in their bodies, but in most it was thought to ...
