Common ICU practice may increase risk of patient death

Glutamine and Antioxidants in the Critically Ill Patient: A Post Hoc Analysis of a Large-Scale Randomized Trial

A common practice for patients with multiorgan failure in intensive care units (ICUs) may actually increase the risk of patient death, according to research published today in the online issue of the Journal of Parenteral and External Nutrition (JPEN), the flagship journal of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.).

Researchers with the Canadian Critical Care Trials Group found that patients who received glutamine supplements either alone or combined with antioxidants had a significantly higher mortality rate than those who did not receive supplements.

Study author Daren K. Heyland, MD, of Kingston General Hospital, Canada, reports that he and fellow researchers discovered that ICU patients with multiorgan failure who received the supplements had a four to eight percent higher mortality rate than those who received a placebo. It was also found that supplements were most harmful in patients with baseline renal dysfunction.

Glutamine supplements have been commonly given to ICU patients with multiorgan failure to replace key nutrients that are often lacking. These nutrients play a central role in the body's immune system reaction to infections, a common problem in ICUs. Patients infected in ICUs are twice as likely to die during treatment as compared with noninfected patients. Supplements are also used to combat muscle mass loss during prolonged ICU stays.

While it is vital to keep ICU patients strong enough to fight off infections, the current method may be too harmful to continue for patients with multiorgan failure based on this new study. Until more safety and efficacy data become available, the study's researchers suggest that glutamine and antioxidants not be administered to critically ill patients with multiorgan failure, particularly those with concomitant acute renal failure.

INFORMATION: Funding for the study was provided by the Canadian Institutes of Health Research; ClinicalTrials.gov number: NCT00133978. Fresenius Kabi provided the glutamine supplements and an unrestricted grant-in-aid. Biosyn provided the intravenous selenium to all participating European sites. The study involved more than 1,200 patients across 40 ICUs in North America and Europe.

A publication of the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.), the Journal of Parenteral and Enteral Nutrition (JPEN) is the premier scientific journal of nutrition and metabolic support. It publishes original, peer-reviewed studies that define the cutting edge of basic and clinical research in the field. It explores the science of optimizing the care of patients receiving enteral or intravenous therapies. All published JPEN articles are available online at http://pen.sagepub.com.

Gender may contribute to recovery time after concussion

2014-05-06

OAK BROOK, Ill. – A study of concussion patients using diffusion tensor imaging (DTI) found that males took longer to recover after concussion than females did. Results of the study, which show that DTI can be used as a bias-free way to predict concussion outcome, are published online in the journal Radiology. Each year, more than 17 million Americans suffer a mild traumatic brain injury (mTBI), more commonly known as a concussion, of which approximately 15 percent suffer persistent symptoms beyond three months. Assessing outcomes and recovery time after concussion ...

Distinct avian influenza viruses found in Antarctic penguins

2014-05-06

An international team of researchers has, for the first time, identified an avian influenza virus in a group of Adélie penguins from Antarctica. The virus, found to be unlike any other circulating avian flu, is described in a study published this week in mBio®, the online open-access journal of the American Society for Microbiology. While other research groups have taken blood samples from penguins before and detected influenza antibodies, no one had detected actual live influenza virus in penguins or other birds in Antarctica previously, says study author and Associate ...

Early obesity linked to increased probability of severe obesity later in life

2014-05-06

Ann Arbor, MI, May 6, 2014 – Exposure to long-term obesity has become more common with increases in obesity at younger ages. Researchers examined the relationship between BMI at age 25, obesity later in life, and biological indicators of health. They found that people who were obese by age 25 had a higher chance of more severe obesity later in life, but that current weight, rather than the duration of obesity, was a better indicator of cardiovascular and metabolic risk. Their findings are published in the June issue of the American Journal of Preventive Medicine. Investigators ...

Factors leading to diabetes may contribute to milk supply problems for new mothers

2014-05-06

New studies provide fresh evidence that the same factors that lead to diabetes contribute to low milk supply in some new mothers. In a study to be presented May 5, Cincinnati Children's Hospital Medical Center researchers discovered that problems with mothers' insulin metabolism may affect their milk production. The study found that women diagnosed with low milk supply were 2.5 times more likely to have experienced gestational diabetes compared to women seen at the clinic solely because their infants were having problems latching onto the breast. "We need to better ...

Having eczema may reduce your risk of skin cancer

2014-05-06

Eczema caused by defects in the skin could reduce the risk of developing skin cancer, according to new research by King's College London. The immune response triggered by eczema could help prevent tumour formation by shedding potentially cancerous cells from the skin. There is ongoing debate surrounding allergic diseases and their impact on the likelihood of developing cancer, with some studies suggesting that eczema is associated with a reduced risk of skin cancer. However, it is difficult to draw firm conclusions based on studies of human populations because eczema ...

Annals of Internal Medicine tip sheet for May 6, 2014

2014-05-06

1. Deaths decline after Massachusetts' health care reform Deaths declined significantly in Massachusetts four years after comprehensive health care reform, according to an article being published in Annals of Internal Medicine. In 2006, Massachusetts enacted a health care law that expanded Medicaid, offered subsidized private insurance, and created an individual mandate. As the model for the Affordable Care Act, effects of the Massachusetts' health care overhaul have important policy implications. Researchers wanted to find out if expanded insurance coverage affected ...

Significant decline in deaths after Massachusetts' health reform

2014-05-06

Boston, MA — In the first four years after Massachusetts instituted comprehensive health reform in 2006, mortality in the state decreased by 2.9% compared with similar populations in states that didn't expand health coverage, according to a new study led by Harvard School of Public Health (HSPH) researchers. They estimated that Massachusetts' health reform law, which provided near-universal coverage, has prevented approximately 320 deaths per year—one life saved for each 830 people gaining insurance. The study—which provides new scientifically rigorous analysis of whether ...
