Poor quality of life may contribute to kidney disease patients' health problems

Future studies should assess whether improving quality of life can protect patients' health

2014-04-04

(Press-News.org) Washington, DC (April 3, 2014) — Kidney disease patients with poor quality of life are at increased risk of experiencing progression of their disease and of developing heart problems, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The findings suggest that quality of life measurements may have important prognostic value in these individuals.

Approximately 60 million people globally have chronic kidney disease (CKD). Quality of life has been well-studied in patients with end-stage kidney disease, but not in patients with CKD who do not yet require dialysis. To gain a better understanding of quality of life among such patients, Anna Porter, MD (University of Illinois at Chicago) and her colleagues studied1091 African Americans with hypertensive CKD enrolled in the African American Study of Kidney Disease and Hypertension Trial and Cohort Studies. The researchers assessed health-related quality of life, including mental and physical health, through surveys.

During approximately 10 years of follow-up, lower physical and mental health scores were linked with increased risks of experiencing cardiovascular events or dying from heart-related causes as well as with experiencing progression of CKD or dying from kidney-related causes.

"Quality of life is extremely important to patients and is impacted by kidney disease," said Dr. Porter. "In order to better serve our patients, physicians need to gain a better understanding of the negative impact that kidney disease has on quality of life, and to recognize the association between quality of life and other outcomes."

INFORMATION: Highlight In African American patients with chronic kidney disease, poor quality of life was linked with increased risks of disease progression and heart problems. 60 million people globally have chronic kidney disease.

Walking may help protect kidney patients against heart disease and infections

2014-04-04

Washington, DC (April 3, 2014) — Just a modest amount of exercise may help reduce kidney disease patients' risks of developing heart disease and infections, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). Heart disease and infection are major complications and the leading causes of death in patients with chronic kidney disease. It is now well established that immune system dysfunction is involved in both of these pathological processes. Specifically, impaired immune function predisposes to infection, while ...

Insomnia may significantly increase stroke risk

2014-04-03

The risk of stroke may be much higher in people with insomnia compared to those who don't have trouble sleeping, according to new research in the American Heart Association journal Stroke. The risk also seems to be far greater when insomnia occurs as a young adult compared to those who are older, said researchers who reviewed the randomly-selected health records of more than 21,000 people with insomnia and 64,000 non-insomniacs in Taiwan. They found: Insomnia raised the likelihood of subsequent hospitalization for stroke by 54 percent over four years. The incidence ...

Higher total folate intake may be associated with lower risk of exfoliation glaucoma

2014-04-03

BOSTON (April 4, 2014) — Exfoliation glaucoma (EG), caused by exfoliation syndrome, a condition in which white clumps of fibrillar material form in the eye, is the most common cause of secondary open-angle glaucoma and a leading cause of blindness and visual impairment. Effective strategies for preventing this disease are lacking. Elevated homocysteine, which may enhance exfoliation material formation, is one possible risk factor that has received significant research attention. Research studies demonstrate that high intake of vitamin B6, vitamin B12 and folate ...

Off the shelf, on the skin: Stick-on electronic patches for health monitoring

2014-04-03

CHAMPAIGN, Ill. — Wearing a fitness tracker on your wrist or clipped to your belt is so 2013. Engineers at the University of Illinois at Urbana-Champaign and Northwestern University have demonstrated thin, soft stick-on patches that stretch and move with the skin and incorporate commercial, off-the-shelf chip-based electronics for sophisticated wireless health monitoring. The patches stick to the skin like a temporary tattoo and incorporate a unique microfluidic construction with wires folded like origami to allow the patch to bend and flex without being constrained ...

Calcium waves help the roots tell the shoots

2014-04-03

MADISON – For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer. Gilroy and colleagues, in a March 24, 2014 paper in the Proceedings of the National Academy of Sciences, showed what long had been suspected but long had eluded scientists: that calcium is involved in rapid plant cell communication. It's a finding that has implications for those interested in how plants adapt to and thrive in changing ...

Smoking may dull obese women's ability to taste fat and sugar

2014-04-03

Cigarette smoking among obese women appears to interfere with their ability to taste fats and sweets, a new study shows. Despite craving high-fat, sugary foods, these women were less likely than others to perceive these tastes, which may drive them to consume more calories. M. Yanina Pepino, PhD, assistant professor of medicine at Washington University School of Medicine in St. Louis, and Julie Mennella, PhD, a biopsychologist at the Monell Center in Philadelphia, where the research was conducted, studied four groups of women ages 21 to 41: obese smokers, obese nonsmokers, ...

Fences cause 'ecological meltdown'

2014-04-03

NEW YORK (Embargoed – Not for release until 14:00 EST 3 April 2014) Wildlife fences are constructed for a variety of reasons including to prevent the spread of diseases, protect wildlife from poachers, and to help manage small populations of threatened species. Human–wildlife conflict is another common reason for building fences: Wildlife can damage valuable livestock, crops, or infrastructure, some species carry diseases of agricultural concern, and a few threaten human lives. At the same time, people kill wild animals for food, trade, or to defend lives or property, and ...

Quantum photon properties revealed in another particle -- the plasmon

2014-04-03

For years, researchers have been interested in developing quantum computers—the theoretical next generation of technology that will outperform conventional computers. Instead of holding data in bits, the digital units used by computers today, quantum computers store information in units called "qubits." One approach for computing with qubits relies on the creation of two single photons that interfere with one another in a device called a waveguide. Results from a recent applied science study at Caltech support the idea that waveguides coupled with another quantum particle—the ...
