A 12-week course of aerobic exercise improved physical function and quality of life in patients with advanced chronic kidney disease.
The exercise program also decreased patients' pain.
More than 20 million people in the United States have chronic kidney disease.
Washington, DC (November 20, 2014) -- Simple yet structured exercise can significantly improve kidney disease patients' quality of life as well as decrease their pain, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). The findings suggest that kidney disease care can and should include exercise as part of an integrative medical approach that emphasizes living well even with chronic illnesses.
Many patients with chronic kidney disease (CKD) report that they have a decreased quality of life because of pain, depression, insomnia, and physical discomforts such as restless leg syndrome and neuropathy.
James Wasserman, MD (Maine Medical Center) and his colleagues looked to see whether a prescribed exercise program could improve physical function as well as quality of life for patients. A total of 107 patients with CKD stages 3 or 4 participated in the study, with 59 undergoing the exercise program and 48 receiving usual care. The overwhelming majority (73%) of those assigned to the exercise group completed the program, which consisted of guided aerobic exercise (treadmill walking and/or stationary cycling) and weight training with free weights, done twice weekly at local physical therapy or cardiac rehabilitation facilities. Additionally, exercise participants were given pedometers and encouraged to walk 5,000 to 10,000 steps per day.
The study showed that a 12-week course of exercise done in a monitored and supervised setting similar to a cardiac rehab center was effective in improving physical function and quality of life. Also, the exercise program decreased pain as assessed by patient questionnaires.
"Kidney specialists who take care of people with chronic kidney disease and end-stage renal disease have been thoroughly trained to use medicines and technology in a "disease-oriented" model of patient care, and we've been able to use these medicines and technologies like dialysis to help people live longer, but we've hit a wall of sorts in helping people live better with their chronic and incurable kidney disease," said Dr. Wasserman. "I think that is why leaders in academic nephrology and the nephrology community in general are now beginning to explore the limitations of this 'disease-oriented' approach, and consider applying a more 'patient-centered' approach to care that emphasizes additional ways to address patients' needs and the importance of living well with chronic disease."
In an accompanying editorial, Manisha Jhamb, MD, MPH (University of Pittsburgh School of Medicine) and Daniel Weiner, MD, MS (Tufts-New England Medical Center) noted that while several questions remain, "the results of this study add substantially to the current knowledge of the effects and efficacy of exercise in people with CKD and have important clinical and research implications." They added that the study highlights that "the time has come for the nephrology community to catch up to our cardiology and pulmonary colleagues by adding renal rehabilitation programs to the list of widely available and frequently accessed resources for patients with chronic medical conditions."

Pain, discomfort and magnet displacement were documented in a small medical records review study of patients with cochlear implants (CIs) who underwent magnetic resonance imaging (MRI), according to a report published online by JAMA Otolaryngology-Head & Neck Surgery.
A CI can help patients with severe to profound hearing loss and about 300,000 people worldwide have the device. However, undergoing MRI can pose concerns for patients with CI because of exposure of the internal magnet to a strong electromagnetic field. There have been previous reports of adverse events, ...
Philadelphia, PA--The control of certain childhood diseases is difficult, despite high vaccination coverage in many countries. One of the possible reasons for this is "imperfect vaccines," that is, vaccines that fail either due to "leakiness," lack of effectiveness on certain individuals in a population, or shorter duration of potency.
In a paper publishing today in the SIAM Journal on Applied Mathematics, authors Felicia Magpantay, Maria Riolo, Matthieu Domenech de Celles, Aaron King, and Pejman Rohani use a mathematical model to determine the consequences of vaccine ...
A new nationally representative survey of employers--the largest purchasers of health care in the country-- shows that most are unfamiliar with objective metrics of health plan quality information. The survey, conducted by The Associated Press-NORC Center for Public Affairs Research, also found that employers are looking to the Affordable Care Act (ACA) as they make significant decisions on the benefits they offer, with the costs of health plans as a key consideration. Funding for the survey was provided by the Robert Wood Johnson Foundation.
"There appears to be a serious ...
PROVIDENCE, R.I. [Brown University] -- In preparation for his upcoming fieldwork, Brown University research analyst Jay Dickson took 10,000 pictures of the inside of his freezer. He wasn't investigating disappearing food or making sure the light went off when he closed the door. Dickson was making sure his new camera and timer would function properly for long periods in sub-freezing temperatures.
"Everything worked great in the freezer for five weeks," Dickson said, "so hopefully it will all work in the field."
That camera's next stop: a remote Antarctic outpost, where ...
Chester, CA-- A study just published by Point Blue Conservation Science shows the benefits of an aggressive approach to restoring Sierra Nevada aspen stands (Populus tremuloides).
Most of the aspen stands that dotted the Sierra Nevada less than a century ago are gone or in poor health. Aspen stands can increase groundwater, enrich soils and support a higher diversity of plants and wildlife, relative to adjacent forest types. Keeping aspen stands as part of our forests is critical to maintaining a healthy Sierra Nevada forest ecosystem for people and wildlife.

Irvine, Calif., Nov. 20, 2014 -- Recent studies showing acid ceramidase (AC) to be upregulated in melanoma, lung and prostate cancers have made the enzyme a desired target for novel synthetic inhibitor compounds. This week in Angewandte Chemie, a top journal in chemistry, UC Irvine and Italian Institute of Technology scientists describe the very first class of AC inhibitors that may aid in the efficacy of chemotherapies.
AC, which is encoded by the ASAH1 gene, plays an important role in the regulation of cell fate, setting the balance between pro-aging/death and pro-life ...
A Washington family of four must spend 46 percent more on average to make ends meet today than 13 years ago, according to a new report from the University of Washington.
The Self-Sufficiency Standard for Washington State 2014, released Thursday (Nov. 20), provides a sobering look at how much it costs individuals and families statewide to meet basic needs -- and how far short they're falling.
The study found that Washington families with two adults, a preschooler and a school-aged child saw the costs of meeting their most basic requirements jump as much as 72 percent ...

Additionally, increased costs associated with prediabetes and undiagnosed diabetes highlight the growing importance of prevention and early intervention.
The study, which follows up on a similar report published ...
TAMPA, Fla. - Moffitt Cancer Center researchers are taking a unique approach to understanding and investigating cancer by utilizing evolutionary principles and computational modeling to examine the role of specific genetic mutations in the Darwinian struggle among tumor and normal cells during cancer growth.
Cells become malignant by acquiring genetic mutations that lead to increased survival and reproduction. Many researchers in the past have viewed cancer progression as the result of unlimited accumulation of these genetic mutations. However, Moffitt researchers ...
