New Research: Finding kidney disease
Researchers found measuring creatinine and cystatin C — two markers for chronic kidney disease — more precisely estimates kidney function than either marker alone. Creatinine is a waste product from protein in the diet and the normal breakdown of muscle tissue. Cystatin C is released by cells throughout the body. The kidneys remove both creatinine and cystatin from the blood. As kidney function worsens, the creatinine and cystatin levels in the blood increase.

Health Tip: Know when to break
There's no absolute overtraining answer that applies to everyone, so it's important to stay in tune with your own body. If you have insomnia, headaches or muscle and joint fatigue that lingers, your body may be telling you to take a break. Remember, rest is the best way to cure overtraining.

Children’s Health: How many weeks are you?
Researchers found achievement scores for children born at 37 and 38 weeks' gestation were significantly lower than those of children born at 39, 40 or 41 weeks. Compared with children born at 41 weeks, children born at 37 weeks have a 23 percent increased risk of having a moderate reading impairment; children born at 38 weeks have a 13 percent increased risk. Math scores were also lower for children born at 37 or 38 weeks.
