Multi-faceted strategy improves nutritional support for ICU patients, but not outcomes

A strategy to change practice in intensive care units was effective in implementing earlier nutritional support for critically ill patients, but the change did not result in a reduced risk of death or reduced length of stay in the ICU, according to a study in the December 17 issue of JAMA, the Journal of the American Medical Association.

Low-glycemic foods better for glycemic control than high-fiber

Persons with type 2 diabetes who had a diet high in low-glycemic foods such as nuts, beans and lentils had greater improvement in glycemic control and risk factors for coronary heart disease than persons on a diet with an emphasis on high-cereal fiber, according to a study in the December 17 issue of JAMA, the Journal of the American Medical Association.

Evolutionary roots of ancient bacteria may open new line of attack on cystic fibrosis

The redox-active pigments responsible for the blue-green stain of the mucus that clogs the lungs of children and adults with cystic fibrosis (CF) are primarily signaling molecules that allow large clusters of the opportunistic infection agent, Pseudomonas aeruginosa, to organize themselves into structured communities.

Both theories about human cellular aging supported by new research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.
