The device addresses safety concerns and size limitations associated with adult kidney dialysis equipment, which can lead to dehydration an...
African Americans are less likely to receive kidney/pancreas transplants than similar patients in other racial groups, despite increased Medicare coverage. Physician bias may be a contributing factor, with doctors assuming African Americans have type 2 diabetes when they may actually qualify for type 1 diabetes.
Declining kidney function increases the risk of heart failure and premature death. Treatments that slow kidney function decline may safeguard heart health by stabilizing it in the normal range before kidney disease develops.

A new study found that switching to a newer type of immunosuppressant drug, sirolimus, reduced the rate of skin cancer in kidney transplant patients by 25%. Nearly half of patients stopped treatment due to side effects. The researchers believe this could offer a new option for reducing skin cancer risk in transplant recipients.
Women with chronic kidney disease are more likely than men to be undiagnosed, according to a new study. The study found that primary care physicians need more education on diagnosing CKD, which could lead to improved patient outcomes and cost savings.
A new study published by the American Society of Nephrology suggests that having a history of lupus does not significantly increase the risk of developing lupus nephritis in recipients of a kidney transplant. The study found that lupus nephritis occurred in just 2.44% of patients, and was associated with only a 7% risk of organ loss.
Researchers found that oral activated charcoal lessens atherosclerotic lesions in experimental mice with kidney damage. This effect appears to be related to reduced inflammation in the blood vessels, regardless of treatment timing or changes in blood pressure or cholesterol levels.

This could lead to an additional 1,000 kidneys or more per year being made available to patients waiting for a transplant.
A Monash University study has identified the role of microscopic antennas in the kidney's repair process, shedding light on a potentially fatal disease. The research, led by Dr. James Deane, showed how hair-like structures called cilia change their length in response to injury, amplifying signals that turn off the repair process.
