Gene for Increased Calcium Absorption Raises PCa Risk

Schwartz, PhD, and colleagues found that men in the highest quartile of calcium intake had a 2.2 times increased risk of localized and advanced PCa compared with men in the lowest quartile.

Estimated glomerular filtration rate (eGFR) is linked just as tightly to chronic kidney disease (CKD) complications as the more invasive and cumbersome iothalamate GFR (iGFR) test in a recent study, results that challenges the conventional view that iGFR is the gold-standard measure of kidney function.
