Many popular diet plans are based on changing the proportion of carbohydrates, proteins, and fats in the diet. There has been some controversy regarding the effectiveness of these diets. A new study accepted for publication in the Journal of Clinical Endocrinology & Metabolism (JCEM) examines the relative ability of different nutrient types to suppress ghrelin, which is secreted by the stomach and is the only known appetite-stimulating hormone. Circulating ghrelin levels increase shortly before meals and then decrease promptly after ingestion of food.

One in four Americans in the hospital right now has a urinary catheter. One percent of them will get a urinary tract infection from that catheter. All of those will require antibiotics. A few may suffer life-threatening complications. And with every new case, UTIs will retain their title of “most common hospital-acquired infection,” responsible for 40 percent of infections related to hospitalization.
But despite all this, a new study finds, American hospitals don’t seem to have a consistent strategy for preventing catheter-related UTIs. In fact, the study shows, most hospitals aren’t using basic tactics that have been proven to keep patients from getting catheter-related UTIs in the first place.
