New study shows intravenous glutamine reduces ischemia reperfusion injuries
2015-06-09
(Press-News.org) A single dose of intravenous glutamine (GLN) administered immediately after a non-lethal lower limb ischemia reduces the reperfusion inflammatory reaction locally and systemically according to a new study.
The study, published today in the OnlineFirst version of the Journal of Parenteral and Enteral Nutrition (JPEN), the research journal of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.), used a mice model to compare the effects of GLN on hind limb ischemia reperfusion (IR) injury.
The study subjected three groups of mice to 90 minutes of ischemia followed by a variable period of reperfusion. A fourth group was used as a control.
In summary, the study showed that GLN reduced the gene expressions of inflammatory mediator in muscle tissue and decreased blood macrophage percentage and plasma IL-6 concentrations at the early or late phase of reperfusion. Histological findings also found that remote lung injury was attenuated in IR injury. The results suggest that a single dose of GLN administration immediately after sub-lethal lower limb ischemia reduces the inflammatory reaction locally and systemically; this may offer local and distant organ protection in hind limb IR injury.

A new study finds that supplementing enteral nutrition with Lactobacillus reuteri (L. reuteri) DSM 17938 as a probiotic may reduce the risk of necrotizing enterocolitis (NEC) in premature infants. NEC is a condition where portions of the bowel undergo tissue death. It is the second most common cause of death among premature infants.
The study, published today in the OnlineFirst version of the Journal of Parenteral and Enteral Nutrition (JPEN), the research journal of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.), is a systematic review of randomized ...

Deficiency of vitamin D is a common problem for patients with severe burn injuries and can lead to further health compromise. However, there are no evidence-based guidelines for vitamin D replenishment in such patients.
A new clinical trial by researchers at Cincinnati's Shriners Hospital for Children compared the outcomes of vitamin D2 and D3 supplementation on pediatric burn patients. The results of that research was published today in the OnlineFirst version of the Journal of Parenteral and Enteral Nutrition (JPEN), the research journal of the American Society for ...

Food wasted means money wasted which can be an expensive problem especially in homes with financial constraints. A new study from the Cornell Food and Brand Lab and the Getulio Vargas Foundation, shows that the top causes of food waste in such homes include buying too much, preparing in abundance, unwillingness to consume leftovers, and improper food storage. "Fortunately," notes lead author Gustavo Porpino, PhD candidate at the Getulio Vargas Foundation and Visiting Scholar at the Cornell Food and Brand Lab, "most of the factors that lead to food waste, can be easily remedied ...

Breast cancer patients are four times less likely to have potentially lifesaving surgery if diagnosed as an emergency rather than through an urgent GP referral, according to a new data* published today (Monday).
This is the first study of its kind that looks at how treatment varies across cancers depending on the patients' route to diagnosis.
The report from Cancer Research UK and Public Health England's National Cancer Intelligence Network (NCIN) is being launched at the annual NCIN Cancer Outcomes Conference in Belfast.
It presents the proportion of patients having ...

Housing improvements could reduce malaria cases by half in some settings, according to research published in the open access Malaria Journal.
As mosquitoes become resistant to insecticides and malaria parasites become resistant to drugs, researchers looked at how making changes to houses might contribute to tackling the deadly disease.
Researchers reviewed 90 studies in Africa, Asia and South America comparing malaria cases in traditional houses (mud, stone, bamboo or wood walls; thatched, mud or wood roofs; earth or wood floors) and modern houses (closed eaves, ceilings, ...

CORAL GABLES, Fla. (June 8, 2015) - There are more boys than girls diagnosed with autism spectrum disorder (ASD). Now, a study led by a University of Miami (UM) researcher shows that behaviors relevant to autism are more frequently observed in boys than in girls, whether they're at risk of autism or not.
"The results imply that there may be an overrepresentation of boys with autism, based on sex differences that affect all children," said Daniel S. Messinger, professor of psychology in the UM College of Arts and Sciences and principal investigator of the study. "In other ...

DURHAM, N.C. - How most babies are protected from acquiring HIV from their infected mothers has been a matter of scientific controversy. Now researchers at Duke Medicine provide new data identifying an antibody response that had long been discounted as inadequate to confer protection.
Mother-to-child transmissions account for about 250,000 HIV infections per year worldwide, despite greatly expanded access to antiretroviral drug regimens that can interrupt transmission into low-resource settings. Ongoing problems with access to the drugs, late initiation of the drug regimens ...

At least two and a half million more workers will be needed to provide long-term care to older people in the United States between now and 2030, according to a study by UC San Francisco researchers published in the June 2015 issue of Health Affairs.
The study authors predict that there will be little effect on this demand for new workers even if long-term care use among different racial and ethnic groups changes significantly or if there is a major shift from institutional care to home-based care.
'Even if 20 percent of elderly patients move out of nursing homes into ...
