How to detect malnutrition in patients effectively?
|
Malnutrition is a common problem in patients with cancer and is associated with a poor outcome. The assessment of nutritional status and its evaluation plays an important role in tailoring nutritional support. A study from South Korea evaluates the relationships between objective and subjective nutritional assessment of gastric cancer patients and suggests that a specific tailored nutritional assessment is needed for accurate measurement of the nutritional status of gastric cancer patients.

Why fad diets work well for some, but not others
|
Using fruit flies, researchers have found that genes interacting with diet, rather than diet alone, are the main cause of variation in metabolic traits, such as body weight. This helps explain why some diets work better for some people than others, and suggests that future diets should be tailored to an individual's genes rather than to physical appearance.

Inhibiting fatty acids in immune cells decreases atherosclerosis risk
|
Scientists have found a way to significantly reduce atherosclerosis in mice that does not involve lowering cholesterol levels or eliminating other obesity-related problems. They did it by interfering with production of a substance called fatty acid synthase, an enzyme that converts dietary sugars into fatty acids in the liver.

Chronic excess of linoleic acid (omega 6), coupled with a deficiency in alpha-linoleic acid (omega 3), can increase obesity down the generations. Researchers exposed several generations of male and female adult and young mice to a "Western-like" diet of this type, and then assessed the consequences of such a lipid environment in the human diet.

Hungry cells, on a binge, know their own limits

Cells that consume parts of themselves can stop this process autonomously as well, according to new research. The self-cannibalism is part of the normal digestive process of the cell, but also a survival mechanism in times of famine. This is what makes it difficult for doctors to 'starve out' cancer cells, for instance.

Insight into why low calorie diet can extend lifespan -- even if adopted later in life
|
Research is providing new insight into why a restricted diet can lead to a longer lifespan and reduced incidence of age-related diseases for a wide variety of animals. Scientists have known for some time that a restricted diet can extend the lifespan of certain animals but this work shows how it affects aging mechanisms - and significantly has also shown that the effects occur even if the restricted diet is adopted later in life.

Adiposity hormone, leptin, regulates food intake by influencing learning and memory
|
The hormone leptin reduces food intake, in part, by activating the hippocampus, an area of the brain that controls learning and memory function, according to new research. Researchers found that when leptin was delivered directly to the hippocampus in rats, the animals consumed less food and lost body weight. Leptin delivered to this region of the brain also impaired the ability of the animals to learn about the spatial location of food.
