A 30 percent increase in chronic kidney disease over the past decade has prompted the US Renal Data System to issue for the first time a separate report documenting the magnitude of the disease, which affects an estimated 27 million Americans and accounts for more than 24 percent of Medicare costs. The USRDS is funded by the National Institute of Diabetes and Digestive and Kidney Diseases, part of the National Institutes of Health.

The number of adults with doctor-diagnosed arthritis is projected to increase to 67 million by 2030, and a large proportion of US adults will limit their activity as a result, according to the US Centers for Disease Control and Prevention. Now, in a new study, University of Missouri researchers found that adults with arthritis who received exercise interventions that included educational components significantly increased their physical activity levels and experienced improvements in pain and physical functioning.

A new study in the Journal of Agricultural and Food Chemistry measured the antioxidant content of cocoa powders and chocolate products. Natural cocoa powder was shown to have the highest content of flavanols — the main antioxidant in cocoa products. Further, alkalinization of cocoa products can deplete the antioxidant content, but that depletion depends on the degree of alkalinization. Light and moderately treated cocoa products can retain significant amounts of the antioxidants.

Scientists have deciphered the complete genetic sequence of the parasite Plasmodium vivax, the leading cause of relapsing malaria, and compared it with the genomes of other species of malaria parasites. The findings shed light on distinctive genetic features of P. vivax, and may lead to new tools to prevent and treat P. vivax malaria. Results of the study, funded by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, appear in the Oct. 9 issue of Nature.
