Major geographic disparities in access to kidney transplantation

Major geographic disparities in access to kidney transplantation

There is substantial geographic variation in access to kidney transplantation among the more than 4000 US dialysis facilities that treat patients with kidney failure, with a disproportionate lack of access to those in the Southeast. Certain factors, which are described in several papers published in the American Journal of Transplantation , seem to explain these differences, and they underscore the need for political, financial, and health systems changes to reduce transplant inequities across the country Continue reading

Blacks with financial worries have lower health scores

Feeling stress about finances leads some Black adults to rate their health more poorly, finds a new study in the American Journal of Health Behavior . While lower income and education among minorities have been linked to poor health for decades, this study focused just on the connection between financial worries and poor health. “Because the study was cross-sectional, we cannot say that one caused the other, but we know that financial strain is associated with poorer self-rated health among black adults,” said the study’s lead author Lorraine R.

Nanoparticles cause cancer cells to self-destruct

Using magnetically controlled nanoparticles to force tumor cells to ‘self-destruct’ sounds like science fiction, but could be a future part of cancer treatment, according to research from Lund University in Sweden.

Experts challenge super food claims: Healthy-giving properties of broccoli, blueberries, may not make it past the gut

Experts challenge super food claims: Healthy-giving properties of broccoli, blueberries, may not make it past the gut

ScienceDaily (Oct. 5, 2012) — They have been the mainstay of the health industry for the best part of a decade, but now researchers at London’s Kingston University are using an approach that allows them to delve deeper into the effectiveness of health-promoting ‘super foods’ and their elixir-giving ilk. While there’s no doubt foods such as broccoli, blueberries and whole grains contain polyphenols – compounds that have antioxidant and anti-inflammatory properties – the academic experts contend that little of these health-giving properties actually make it past the gut Continue reading
